Description

Double-path double-vision monitoring equipment with lifting device

Technical Field

The utility model relates to the technical field of monitoring equipment, in particular to double-path double-vision monitoring equipment with a lifting device.

Background

The monitoring equipment is widely applied in the field of industrial equipment and is used for monitoring and inspection work of sites, equipment and the like. The method is ideal for ensuring the site safety and effectively guaranteeing the personal safety of the patrol personnel. Because the monitoring equipment can have basic characteristics of perception, execution and the like, the dangerous, heavy and complex work of inspection can be assisted or even replaced by human beings, and the working efficiency and quality are improved.

However, existing monitoring devices are not capable of conveniently adjusting their height in real time, i.e., they are not capable of adjusting the monitoring height in a real-time, flexible, controllable, convenient and reliable manner to achieve more flexible monitoring. And, there is generally no flexible multiple monitoring measure in the industry.

However, in some application occasions, for example, in a belt conveyor monitoring occasion, if only one path of double vision module is adopted, the lifting device is required to lift from the upper part of the belt to the lower belt carrier roller, the lifting stroke is larger, the inspection efficiency is lower, the monitoring of the upper belt and the upper belt carrier roller or the lower belt carrier roller can be simultaneously completed by adopting double paths of double vision, the monitoring efficiency is greatly improved, the stroke requirement on the lifting device is greatly reduced, and only the lifting device is required to lift from the upper belt carrier roller to the lower belt carrier roller.

The information included in this background section of the specification of the present utility model, including any references cited herein and any descriptions or discussions thereof, is included solely for the purpose of technical reference and is not to be construed as a subject matter that would limit the scope of the present utility model.

The utility model is described and illustrated in further detail below with reference to the drawings and specific embodiments.

Fig. 3 is a schematic view of the unidirectional power driven lifting device 100 and the linear guide lifting mechanism 140 thereof shown in fig. 2 in a fully extended state, wherein the linear guide lifting mechanism 140 can drive the sliding blocks of each linear guide lifting mechanism 140 to slide downwards by self gravity from the retracted state shown in fig. 2, so as to achieve a partially extended state or the fully extended state shown in fig. 3.

Fig. 4 is an enlarged partial schematic view of the unidirectional power driven lift apparatus 100 and its linear guide lift mechanism 140 shown in fig. 3, schematically illustrating the construction and configuration of the linear slide-block module of the linear guide lift mechanism 140, the arrangement of the hoist ropes and cables, etc.

As shown in fig. 1-6, a unidirectional power driven lifting device 100 for a monitoring apparatus and its components, as well as associated parts of a monitoring apparatus, according to an embodiment of the utility model are schematically illustrated. The lifting device 100 may include an upper platform 110, the upper platform 110 being configured to be directly or indirectly mounted on a rail 500 on which the monitoring apparatus operates and may be driven to travel along the rail 500. As shown in fig. 1-2, the lifting device 100 is mounted and connected to the upper platform 110, and the upper platform 110 is fixedly mounted on the roller assembly 400 rolling on the rail 500. When the roller assembly 400 runs along the rail 500, the monitoring module 300 together with the elevating device 100 thereof also runs along the rail 500 for inspection. As shown in fig. 1-2, one example of the roller assembly 400 may include 4 pairs of rollers, and a mounting bracket operable for mounting the 4 pairs of rollers on the rail 500, which includes left and right saddles (not identified in fig. 1) on which are mounted 1 pair of upper rollers rolling on left and right sides of the top surface of the square rail 500, and 1 pair of lower rollers rolling on left and right sides of the bottom surface of the square rail 500. Similarly, 1 pair of upper rollers rolling on the left and right sides of the top surface of the square rail 500 and 1 pair of lower rollers rolling on the left and right sides of the bottom surface of the square rail 500 are mounted on the left saddle. A wheel assembly driving motor (not shown) may be further installed on the left saddle of the wheel assembly 400 as shown in fig. 1, for driving the wheel assembly 400 to operate.

The monitoring module 300 may be any device, functional module, or any combination thereof, such as a video or picture camera, a thermal imaging device such as an infrared camera, a gas detector, a temperature sensing device, etc., as may be desired for an application, which may be used for inspection, monitoring, detection, measurement, sensing, etc.

Fig. 2 is another perspective view of the linear guide rail elevating mechanism 140 of the one-way power driven elevating device 100 shown in fig. 1, with the housing removed to show its internal configuration, and with the elevating device 100 and its linear guide rail elevating mechanism 140 in a fully retracted state, the linear guide rail elevating mechanism 140 needs to be driven by the electric power of the motor 170 to retract to a folded state when retracted.

The lifting device 100 may include a lower platform 120 and the monitoring module 300 may be mounted on the lower platform 120 as shown in fig. 1-2. The linear guide elevating mechanism 140 is installed at the lower platform 120, is connected between the upper and lower platforms 110 and 120, and extends in an elevating direction. Specifically, the linear guide lift mechanism 140 may include n (n is an integer of 2 or more, such as 3 or more or 4 or more) linear slide-and-slider modules (linear slide-and-slider modules are sometimes referred to in the industry as linear guides, linear guide modules, etc.) operatively connected in sequence extending along the lift direction. The 1 st linear rail-slider module of the n linear rail-slider modules is fixedly connected to the upper platform 110, and the nth (the lowest, i.e., the last, in fig. 3) linear rail-slider module of the linear rail-lifting mechanism 140 is mounted and connected to the lower platform 120.

According to one example, n.gtoreq.5, so that, for example, in the case where n is equal to 5, there are also 3 linear-slide-block modules connected slidably relative to one another between the 1 st and 5 th linear-slide-block modules.

Fig. 6 is a schematic diagram illustrating one embodiment of a linear slide-block module of linear guide lift mechanism 140. Each linear rail-slider module has a rail 141 and a slider 143 combined with the rail 141 and linearly slidable along the rail 141. Such linear slide-and-slider modules are standard mechanical parts that are commercially available, and an example thereof may be, for example, MGW12H1R400 zfcm+u8 linear guide. All linear rail-slide modules of linear rail lift mechanism 140 are preferably of the same type, which facilitates installation and stowing of the stack. According to one example, the linear slide-block module may incorporate balls to facilitate reliable and smooth linear sliding of the block on the slide rail.

However, the individual rails or blocks may be slightly different or modified based on the needs, for example, the rails of the first linear rail-block module shown in fig. 3 may have a reinforcement 145 added thereto for reinforcement and for facilitating the installation/folding of other parts, and the rails of the last linear rail-block module may be similarly modified, but these are optional and have no essential effect on the practice of the present utility model and are within the scope of the present utility model.

Fig. 5 is a further enlarged partial schematic view of the linear guide elevating mechanism 140 shown in fig. 4. An upper stop 142 in the form of an upper stop may be provided on the upper end of the linear rail-slide block module of the linear rail lifting mechanism 140, and a lower stop 144 in the form of a lower stop may be provided on the lower end thereof. Thus, when the previous slider 143 fixedly connected to the next rail 141 is lowered into place by gravity, it is stopped by the lower stopper 144 provided at the lower end of the previous rail 141 to further slide down. When the last slider 143 fixedly connected to the next rail 141 is driven to travel upward by the motor, the next linear slide 151 rail-slider module travels upward to gradually overlap the last linear rail-slider module, and at this time, the upper end thereof (preferably, the upper stopper 142 in the form of its upper stopper) is pushed against the upper stopper 142 of the last linear rail-slider module and thereby pushes the upper stopper 142 of the last linear rail-slider module to continue traveling upward until it is pushed against the next upper stopper 142 again. This retraction action begins with the lowermost one, i.e., the linear rail-slide module attached to the lower platform 120, retracting and jacking, and so on and progressively pushing until the linear rail lift mechanism 140 is fully retracted, as further described below.

According to one embodiment, the lower end of the 1 st linear rail-slider module is provided with a lower stopper, and the upper and lower ends of each of the 2 nd to nth linear rail-slider modules are provided with upper and lower stoppers, respectively. Preferably, an upper stop portion may also be provided at the upper end of the 1 st (i.e., the uppermost one fixed to the upper platform 110) linear slide-block module, so that when the lifting device is fully retracted, the upward stroke or trend thereof is restrained by the upper stop portion, thereby further improving the safety and reliability of the entire lifting mechanism.

According to one embodiment, the slide 143 of the 1 st linear-slide-block module is fixedly connected with the slide 141 of the 2 nd linear-slide-block module, the slide 143 of the 2 nd linear-slide-block module is fixedly connected with the slide 141 of the 3 rd linear-slide-block module, and so on … until the slide 143 of the n-1 st linear-slide-block module is fixedly connected with the slide 141 of the n-th linear-slide-block module.

The position of the fixed connection of the slider 143 with the slide rail 147 of the next linear slide-slider module is not particularly limited, and basically, the extended and retracted states of the lifting device of the present utility model can be realized. However, as a preferred embodiment, in the fully extended state, the slider 143 of the 1 st linear-slide-and-slide module is fixedly connected to the substantially upper end position of the slide rail 141 of the 2 nd linear-slide-and-slide module at the substantially lower end position of the 1 st linear-slide-and-slide module, the slider 143 of the 2 nd linear-slide-and-slide module is fixedly connected to the substantially upper end position of the slide rail 141 of the 3 rd linear-slide-and-slide module at the substantially lower end position of the n-1 st linear-slide-and-slide module, and so on … until the slider 143 of the n-1 st linear-slide-and-slide module is fixedly connected to the substantially upper end position of the slide rail 141 of the n-th linear-slide-and-slide module at the substantially lower end position of the n-1 st linear-slide-and-slide module. This has the advantage that the extension length of each linear rail-slide module can be utilized to a maximum extent and with maximum efficiency.

As shown in fig. 2-5, the lifting device 100 may further comprise a retractable power cable 150, for which purpose a cable mount 151 is mounted on the slide 143 of the one or more linear slide-slide modules, for example on the side of the slide, the power cable 150 being fixed in position at the one or more cable mounts 151. Accordingly, with the unfolding and folding movement of the linear guide elevating mechanism 140, the power supply cable 150 can be correspondingly folded and unfolded along with the sliding block by means of one or more cable mounting pieces 151 in a linkage manner, thereby facilitating the orderly and safe and reliable wiring of the cable, avoiding the fault caused by winding, and saving the space.

Fig. 7 shows a schematic view of the upper platform 120 of the lifting device 100 and the motor mounted thereon, as well as the reel mechanism 130, etc. according to one embodiment. Fig. 8 is a schematic cross-sectional view taken along the rotational longitudinal center axis of the motor, reel mechanism 130, and the like, showing the configuration of the motor, reel mechanism 130, and the like, of fig. 7, schematically showing, among other things, how the screw sleeve-lead screw assembly cooperates with the capstan 132, and the like. Fig. 9 is a diagram illustrating the construction and configuration of the associated limit switches of the lifting device 100 and the reel mechanism 130 according to one embodiment. Fig. 10 is a schematic diagram showing the arrangement and assembly of the motor 170 of the lifting device 100 and its reduction mechanism 171, the reel mechanism 130 and its capstan and wire sleeve-screw assembly, etc. according to one embodiment.

As described above, the unidirectional power driven lift 100 also has a motor 170 mountable on the upper platform 110 configured to provide power to drive the lift 100. The unidirectional power driven lift apparatus 100 requires the motor 170 and the lifting rope of the reel mechanism 130 to retract the linear guide rail lift mechanism 140 step by step from the lowest linear guide rail-slider module upwards during the lifting of the linear guide rail lift mechanism 140, i.e. the lifting and lifting of all the linear guide rail-slider modules thereof.

The reel mechanism 130 is coaxially rotatably mounted with the motor 170, such as by a shaft coupling. The reel mechanism 130 includes a winch 132 and a hoist rope 131 wound around the winch 132, wherein the hoist rope 131 is operatively connected, i.e., secured, to the nth, i.e., lowermost, linear slide-and-slide module and the entire linear guide elevating mechanism 140 are pulled up by the hoist rope 131 when retracted, and the lower platform 120, the monitoring module 300, which is fixedly connected to the lowermost linear slide-and-slide module, are retracted up together. As shown in fig. 3, the nth, i.e., the lowermost, linear rail-slide module, which may be provided with reinforcement members 146, is fastened to the lower platform 120 by means of the support 160, and the monitoring module 300 is also fastened to the lower platform 120, for example, to its bottom surface. The support 160 may be in the form of a reinforcing plate/baffle (only one reinforcing plate/baffle is shown on each side of the linear rail-slide module) such that the support 160 not only serves to assist in mounting and strength of the structure, but the support 160, lower platform 120 and nth linear rail-slide module together form a "dock" like seat for receiving the linear rail lift mechanism 140, serving as a linear rail-slide module for helping to retain and receive the collapsed linear rail lift mechanism 140 in the collapsed condition.

As shown in fig. 7-10, the motor may include a worm gear-worm reduction mechanism 171 or other form of reduction mechanism such as in the form of gears. The worm wheel-worm reduction mechanism 171 has a self-locking function, and thus can also serve as a braking device for the motor.

The motor 170 and the reel mechanism 130 are both installed on the bottom surface of the upper stage 110, and the driving shaft of the motor 170 forms a shaft connection and a shaft transmission with the reel mechanism 130, thereby transmitting power from the motor 170 to the reel mechanism 130. The reel mechanism 130 may further include a spline feature 1332 that may extend in an axial direction of the drive shaft 133, such as shown in fig. 10, such that the drive shaft 133 may be rotatably and laterally horizontally shiftably keyed to the capstan 132, the drive shaft 133 being coupled to and drivable in rotation by a drive shaft of the worm-gear reduction mechanism 171, such that the capstan 132 may be axially laterally shifted laterally relative to the spline 1332 while being rotatable by the drive shaft 133 via the spline feature 1332 of the drive shaft 133, such as by a screw-and-lead screw assembly, as described in more detail below. Winch 132 is provided with a spiral groove 1321 for receiving a hoist rope 131 wound around winch 132, one example of hoist rope 131 being a wire hoist rope to ensure sufficient strength and life to raise and release linear guide elevating mechanism 140 and lower platform 120 and monitoring module 300 connected thereto. Thus, when the motor-driven capstan 132 rotates in the winding direction, the hoist rope 131 is wound up to retract the linear rail elevating mechanism 140. When the motor-driven capstan 132 rotates in the opposite unwinding direction, the hoist rope 131 is unwound and the linear rail-slider module of the linear rail elevating mechanism 140 slides down by gravity until it is in a fully extended state. Of course, depending on the required inspection height, the hoist rope 131 may also be partially unwound and lowered so that the linear guide elevating mechanism 140 reaches only a partially extended state, which is also possible, at which time a portion of the linear guide elevating mechanism 140, but not the entire linear slide-block module, is extended downward.

To ensure that the lifting rope 131 remains substantially non-displaced in its horizontal position during winding and unwinding, i.e., it is desirable to keep the lifting rope 131 substantially free of horizontal movement relative to the upper platform 110 and motor 170, i.e., always in alignment with respect to the linear guide lift mechanism 140 without substantially horizontal displacement.

7-8, if the lead screw-screw bushing assembly of the present utility model is not provided, the hoist rope 131 will be displaced rightward relative to the linear rail lifting mechanism 140 while being wound up when the motor-driven capstan 132 rotates in the winding direction. This may result in the linear guide elevating mechanism 140 and the entire elevating device 100 not functioning properly. For this reason, it is necessary that the entire winch 132 is displaced to the left in the same extent together with the hoist rope 131 to cancel the rightward displacement of the hoist rope 131 while the hoist rope 131 is wound up. And vice versa, i.e. the entire winch 132 is displaced to the right with the lifting rope 131 at unwinding to counteract the leftward displacement of the lifting rope 131. This ensures that the hoist rope 131 is not substantially horizontally displaced relative to the linear guide lift mechanism 140 during winding and unwinding.

To this end, as shown in fig. 8-10, on the transmission shaft 133 which is keyed to rotate with the capstan 132, on the left side shown in fig. 8, there is provided a screw 133A (as shown) which is preferably integrally formed with the transmission shaft 133 or is mounted, for example, coaxially, on the screw 133A, there is provided a screw thread 1331, on a screw sleeve 135 which is mated with the screw 133A, there is provided a screw thread 1351 which is engaged therewith, and the screw sleeve 135 is connected to the left side of the capstan 132 via a bearing 1352. The left end 133B of the threaded spindle 133A can be rotatably fixed to the left bearing bracket 180 by means of a bearing, for example. The stopper pin 182 fixed to the wire sleeve 135 is fitted into the groove-shaped hole 111, and the diameter of the stopper pin 182 is substantially equivalent to the hole width of the groove-shaped hole 111, and the stopper pin 182 functions not only to assist the reverse rotation of the wire sleeve 135 with respect to the screw rod 133A, but also to function as a stopper and a limit in cooperation with a travel switch, as described below.

Thus, when capstan 132 is rotated in the winding direction such that hoist rope 131 is displaced horizontally, for example, to the right, since stop pin 182 remains in slotted hole 111 to tend to prevent wire sleeve 135 from rotating with capstan 132, wire sleeve 135 will in turn be counter-rotated relative to engaged lead screw 133A, whereby counter-rotation of wire sleeve 135 will cause simultaneous horizontal displacement to the left, thereby simultaneously effecting substantially the same magnitude of horizontal displacement to the left of stop pin 182 and capstan 132 associated therewith, as the engagement between stop pin 182 and length of slotted hole 111 causes stop pin 182 to be displaced horizontally to a degree, and capstan 132, by virtue of the complementary engagement feature with spline feature 1332, to be also caused to be displaced horizontally to the right and left in the axial direction relative to drive shaft 133 (and spline feature 1332) while being rotated by drive shaft 133, such that capstan 132-for example, as a result of the wire sleeve-lead screw assembly, as detailed below, will counteract horizontal displacement to the right of hoist rope 131, thereby maintaining hoist rope 131 substantially free of horizontal displacement to the right.

Vice versa, when the winch 132 rotates in the unwinding direction and the lifting rope 131 thereon is displaced horizontally, for example to the left, the wire sleeve 135 simultaneously brings the winch 132 to counteract the horizontal displacement to the right substantially by the same extent, so that the lifting rope 131 is kept substantially free from axial displacement in the horizontal direction.

For further safety reasons, a stop device may be provided for horizontal displacement of the winch 132 and related components. To this end, the lifting device 100 may be provided with a travel switch defining a starting position and an ending position of the reel mechanism 130. Specifically, as shown in fig. 8 to 9, a slotted hole 111, for example, in the form of an oblong hole or a waist hole, is provided on the upper stage 110, a travel switch 134 is correspondingly arranged at one end (right end as viewed in fig. 9) of the slotted hole 111, and a travel switch 181 is correspondingly arranged at the other end (left end as viewed in fig. 9) of the elongated slot. The limiting device can also comprise a stop pin 182 which is linked with the wire sleeve 135 and the winch 132, the stop pin 182 is matched with the groove-shaped hole 111, when the stop pin 182 moves horizontally to the right along with the winch 132 until the stop pin 134 contacts with the travel switch 134 at the right end, the travel switch 134 sends a stop signal to stop the driving of the motor, and the whole lifting device including the reel mechanism stops moving; when the stopper pin 182 is horizontally displaced to the left along with the winch 132 to hit the travel switch 182 at the right end, the travel switch 134 issues a stop signal to stop the driving of the motor, and the entire lifting device 100 including the reel mechanism 133 is also stopped from moving, thereby achieving the functions of limiting and safe operation. The travel switch 134 may be a mechanical or electromechanical switch, although other suitable types are possible.

In order to ensure smooth winding and unwinding of the hoist rope 131 on the winch 132 at all times without problems such as misalignment and arching, a fixing mechanism 1311 may be provided to fit the hoist rope 131 into and press-fix it with a screw 1312.

The lifting operation of the lifting device 100 according to one embodiment is further described below. Generally, the lifting device 100 is configured to assume two states: (1) A retracted state in which the 2 nd to nth linear rail-slider modules are configured such that the hoist rope is retracted in the ascending direction by the motor-driven reel mechanism 130 and can be stacked in a side-by-side manner, for example; and (2) an extended state in which at least one of the 2 nd to nth linear rail-slider modules is slidingly lowered in the lowering direction by means of gravity, thereby at least partially or fully extending the linear rail elevating mechanism 140 in place in the lowering direction; wherein the lifting device 100 is only driven by unidirectional power of the motor during the transition from the extended state to the stowed state and is extended downwardly by gravity, in particular by the gravity of the slider and the components connected thereto, such as the lower platform and the monitoring module connected to the lowermost one of the sliders, when switching from the stowed state to the extended state, without the power of the motor providing a downward driving force, the motor may be required to provide a braking force to ensure that the lifting device 100 is stopped and stays at the desired extended height. Preferably, the motor is therefore provided with a braking mechanism (if a self-locking worm gear reduction mechanism is provided, no additional braking means are required) so that in the desired partially extended state the motor can also be held in place in the partially extended state by the motor braking mechanism.

To meet the safety, reliability, durability, and moisture protection requirements, the lift apparatus 100 may include an outer shroud 200 that is stowed and extended accordingly as the linear guide lift mechanism 140 is raised and lowered, the outer shroud 200 being sealingly connected between the upper and lower platforms 110, 120. According to an example, the outer shroud 200 may be, for example, an accordion-structured outer shroud.

According to one example, the motor may be of any suitable type, such as a stepper motor, but this example is not intended to be limiting. In general, it is preferable that the motor is arranged so that the lifting speed of the lifting device 100 is 20 cm/sec or more, for example 50 cm/sec or more.

The dual-path dual-vision monitoring device 1000A of the first embodiment is particularly suitable for some applications, such as the belt conveyor 600, where multiple monitoring devices are required, and can be used for real-time and simultaneous multiple monitoring, so as to achieve more comprehensive monitoring, obtain more comprehensive required monitoring parameters, and/or overcome the monitoring blind area.

The lifting device 100 shown in fig. 1-10, which is driven by unidirectional power, such as a motor, that can be operated on the rail 500 by means of the roller assembly 400, can be used in the dual-path dual-vision monitoring apparatus 1000A of the present utility model, although it will be understood by those skilled in the art that other suitable types of lifting devices can be used in the dual-path dual-vision monitoring apparatus 1000A of the present utility model, such as lifting devices that can be driven bi-directionally by motors as well.

As shown in fig. 11 to 15, the dual-path dual-view monitoring apparatus 1000A with the lifting device 100 according to the first embodiment of the present utility model is mainly characterized in that the dual-path dual-view monitoring apparatus 1000A has at least two monitoring modules, wherein one second monitoring module 300A which can be lifted can be mounted on the lower platform 120 of the lifting device 100, and thus can be lifted up and down to flexibly monitor different height portions of the belt conveyor 600, including the lower carrier roller 620; another stationary monitoring module 300B may be mounted to a stationary location of the lifting device 100, such as the upper platform 110, to monitor the position of the belt conveyor 600, particularly in the upper half, including the upper idler rollers 610. The two-way double vision monitoring device 1000A runs on the track 500 by means of the roller assembly 400, whereby other positions of the monitoring belt conveyor can also be patrolled.

Each of the liftable second monitoring module 300A and the fixed first monitoring module 300B is integrated with both a thermal imaging camera and an optical imaging camera. Of course, the second monitoring module 300A and the first monitoring module 300B may further include monitoring devices such as a gas sensor, a temperature sensor, and the like.

Those skilled in the art will thus appreciate that the two-way dual vision monitoring device 1000A allows for higher monitoring efficiency, shorter lifting travel of the lifting arm, provides for more reliable and stable data storage, and provides for more flexible, multiplexed, comprehensive monitoring.

Second embodiment of the two-way Dual-view monitoring device

Fig. 16-17 schematically illustrate a two-way double vision monitoring device 1000B with a lifting apparatus usable in a belt conveyor situation according to a second embodiment of the present utility model, which differs from the two-way double vision monitoring device 1000A of the first embodiment in that the fixed first monitoring module 300B is mounted in a different manner.

As shown in fig. 16 to 17, in the dual-path dual-vision monitoring apparatus 1000B of the second embodiment of the present utility model, the fixed first monitoring module 300B may be fixed to another roller assembly 400 running on the rail 500 instead of being fixed to the upper platform 110 as in the first embodiment. The other roller assembly 400 is connected in series with the roller assembly 400 where the second monitoring module 300A of the lifting device 100 is located, for example, by a connection 700 such as a steel rod. The fixed first monitoring module 300B can thus run on the rail 500 together with the lifting device 100 and the lifting second monitoring module 300A, functioning as a double monitoring.

As another embodiment, the other roller assembly 400 and the roller assembly 400 where the second monitoring module 300A is located may be separated from each other, but may be linked to each other by, for example, wireless communication.

The basic idea of the present utility model is described above in connection with the embodiments. It will be understood by those skilled in the art that the present utility model is not limited to the particular embodiments described herein, and that various obvious changes, rearrangements, combinations, and substitutions can be made by those skilled in the art without departing from the scope of the utility model.
