Description

Liquid storage device with cleaning device

The present invention relates to a liquid storage device, and more particularly to a liquid storage device having a cleaning device.

Many buildings install liquid storage equipment for storing water, such as water towers. Most of these liquid storage equipment are installed on the top floor of buildings, so it is usually inconvenient to clean. Even when cleaning, most of the cleaning personnel can only stand in the liquid storage equipment. In addition, the inside of the liquid storage device is brushed with a long-handled brush. This cleaning method is not only inefficient, but also difficult to clean the water tower. Although some cleaning personnel can enter the inside of the liquid storage device for cleaning, it may contaminate the water storage equipment due to the personal hygiene problems of the cleaning personnel, for example, contamination of unclean clothes, contamination of bacteria in the body and skin, and water storage. The inside of the equipment is a closed and humid environment. These wet environments are easy for the cleaning staff to feel urinary. People with poor moral abilities tend to be convenient under the urgency, resulting in hidden human pollution.

In order to solve the inconvenience and trouble caused by the manual cleaning of the water storage equipment, some people try to use the automatic equipment instead of the manual to clean the water tower. For example, the TW 207134 patent discloses the design of using the motor to drive the rotating of the brush set to clean the inner wall of the water tower, CN 201962734U patent Also disclosed is a water tower automatic cleaning device dedicated to cleaning the bottom wall of the water tower, which is also realized by means of a motor motor driving the cleaning brush to rotate.

However, the conventional water tower cleaning equipment generally has the drawback that the bristles of the cleaning brush always abut against the wall surface of the water tower, causing the bristles to be elastically fatigued very quickly, and since the cleaning of the water tower is often performed at intervals, it is usually only In the first two cleaning operations, the bristles are in good condition, and then the cleaning effect is greatly reduced due to the fatigue fatigue.

Therefore, how to improve the deficiencies of the water tower cleaning equipment is indeed worthy of consideration by those skilled in the art.

The main object of the present invention is to provide a liquid storage device having a cleaning device which can delay the elastic fatigue of the bristles.

In order to achieve the foregoing and other objects, the present invention provides a liquid storage device having a cleaning device, comprising a cylinder and a cleaning device, the cylinder comprising a peripheral wall and a bottom wall disposed at a bottom edge of the peripheral wall, the peripheral wall and the bottom Between the walls, a storage space is defined, the cleaning device has a main shaft, a driving device, a bracket fixed to the main shaft, and at least one cleaning component, the main shaft extends in an axial direction into the liquid storage space, The driving device is configured to drive the spindle to rotate, the cleaning component is pivotally disposed on the bracket, and the pivoting axis of the cleaning component is parallel to the spindle, the cleaning component has a first-class resistance plate, a cleaning brush and a a connecting unit is connected to the flow resistance plate and the cleaning brush; when the main shaft is rotated by the driving device, the fluid in the liquid storage space applies the first resistance F1 of the flow resistance plate, and the fluid in the liquid storage space applies the The second resistance F2, F1 and F2 of the cleaning brush satisfy the following relationship, whereby the cleaning element is rotated about its pivot axis to cause the cleaning brush to abut against the peripheral wall: wherein, the direction of the first resistance is the first The angle between the force arms is the angle between the direction of the force of F2 and a second force arm, the length of the first force arm, the length of the second force arm, and the first force arm is the first resistance The force applying point on the flow resistance plate is the shortest connection with the pivot axis, and the second force arm is the shortest connection of the second resistance to the application point on the cleaning brush and the pivot axis.

With the foregoing design, the cleaning brush will be in close contact with the wall only when the driving device is operated, and the cleaning brush does not continuously adhere to the wall when the driving device is not operated, thereby preventing the cleaning brush from being generated during non-operation. Elasticity is tired.

In order to achieve the above and other objects, the present invention also provides a liquid storage device having a cleaning device, comprising a cylinder and a cleaning device, the cylinder comprising a peripheral wall and a bottom wall disposed at a bottom edge of the peripheral wall, the peripheral wall and a storage space is defined between the bottom walls, the cleaning device has a main shaft, a driving device, a baffle unit and a plurality of ball brushes dispersed in the liquid storage space, wherein the driving device is used to drive the main shaft to rotate, The baffle unit is disposed at a position adjacent to the bottom wall, and the baffle unit and the main shaft are in a synchronous rotating relationship.

With the aforementioned design, the ball brush does not act on the wall surface when it is not working, and can avoid elastic fatigue.

Referring to Figures 1 to 4, the first embodiment of the present invention is illustrated. The liquid storage device 1 includes a cylinder 10 and a cleaning device 20, and the liquid storage device 1 is adapted to store water or other liquids. One of the most common aspects of the liquid storage device 1 is a water tower.

The cylindrical body 10 includes a peripheral wall 11 and a bottom wall 12 disposed at a bottom edge of the peripheral wall 11. A liquid storage space 13 is defined between the peripheral wall 11 and the bottom wall 12. The peripheral wall 11 is preferably a cylindrical shape. However, the actual change can still be made according to the requirements, and the bottom wall 12 can be a curved surface, a plane or other irregular surface. In the preferred embodiment, the cylinder 10 further includes a top wall 14 disposed on the top edge of the peripheral wall 11, a top cover 15 disposed at the center of the top wall 14 and a carrier 16 disposed below the bottom wall 12.

The cleaning device 20 has a main shaft 21, a driving device 22, a bracket 23 fixed to the main shaft 21, two cleaning elements 24, a baffle unit 25, and a plurality of ball brushes 26 dispersed in the liquid storage space 13. Wherein, the main shaft 21 extends in the axial direction into the liquid storage space 13, and the main shaft 21 is preferably located at the geometric center of the liquid storage space 13, and the main shaft 21 and other components that are in contact with each other are relatively rotatable. With bearings. The driving device 22 is configured to drive the spindle 21 to rotate. The driving device 22 is preferably a motor or a combination of a motor and a speed reducing mechanism. The driving device 22 can be fixed to the cylinder 10, for example, to the top cover 15 of the cylinder 10 or Other suitable locations. The cleaning element 24 is pivotally disposed on the bracket 23. In this embodiment, the bracket 23 has a pair of radially extending upper brackets 231 and another pair of radially extending lower brackets 232, and the cleaning elements are pivoted The manner in which the shank is disposed on the bracket 23 includes, but is not limited to, the bracket 23 has a pair of rotating shafts 233 fixed between the upper and lower brackets 231 and 232, and the cleaning component 24 is rotatably sleeved on the rotating shaft 233. Bushing 244; or, in other possible embodiments, the bracket does not have a rotating shaft, and each cleaning element has a rotating shaft rotatably disposed between the upper and lower brackets, but this embodiment is not depicted. The pivot axis X of each cleaning element 24 is parallel to the main shaft 21, and each cleaning element 24 has a first-class resistance plate 241, a cleaning brush 242, and a connecting unit 243 connected to the flow resistance plate 241 and the cleaning brush 242. The unit 243 is configured to allow the flow resistance plate 241 and the cleaning brush 242 to interlock with each other, so that the flow resistance plate 241 and the cleaning brush 242 can be pivoted in synchronization. In this embodiment, the connecting unit 243 has a first segment 2431 connected between the flow resistance plate 241 and the sleeve 244, and a second segment 2432 connected between the cleaning brush 242 and the sleeve 244, but the connecting unit 243 The appearance is not limited to this. The baffle unit 25 is disposed at a position adjacent to the bottom wall 12, and the baffle unit 25 and the main shaft 21 are in a synchronous rotational relationship. The baffle unit 25 is directly or indirectly connected to the main shaft 21, in this embodiment, The baffle unit has two baffles 251 located on the side of the main shaft 21, and the baffle 251 is connected to the lower bracket 232 and indirectly connected to the main shaft 21, but the baffle 251 can also be changed as shown in FIG. The second embodiment is directly connected to the main shaft 21. The ball brush 26 refers to a spherical body or a spheroidal body having bristles on the surface, such as an elliptical body. The ball brush 26 preferably has a specific gravity close to or smaller than that of water (or a liquid stored in other liquid storage devices), so that the ball brush 26 is easy to follow. The water floats on the liquid surface.

As shown in FIGS. 6 and 6A, when the cylinder 10 is to be cleaned, the driving device 22 is activated to rotate the main shaft 21, and the main shaft 21, that is, the driving bracket 23 and the cleaning member 24 are rotated together, and the fluid of the liquid storage space 13 at this time (for example) Water or air) will generate a flow resistance, thereby applying a first resistance F1 of the flow resistance plate 241, and applying a cleaning brush 242 and a second resistance F2, F1 and F2 satisfy the following relationship, thereby causing the cleaning element 24 to pivot around it. The axis rotates to cause the cleaning brush 242 to abut against the peripheral wall 11 to clean the surface thereof: F1 × sin θ1 × r1 > F2 × sin θ 2 × r2; Where θ1 is the angle between the direction of application of the first resistance and a first force arm, θ2 is the angle between the direction of force of F2 and a second force arm, and r1 is the length of the first force arm, r2 Is the length of the second force arm, the first force arm is the shortest connection between the first resistance on the flow resistance plate and the pivot axis, and the second force arm is the second resistance on the cleaning brush The shortest connection between the point and the pivot axis; it can be understood that the first resistance and the second resistance are both composed of air resistance and liquid resistance. When the liquid level in the liquid storage space 13 is higher, the liquid resistance is larger, and the air resistance is The smaller, conversely, the lower the liquid level in the liquid storage space 13, the smaller the liquid resistance, the greater the air resistance, and the liquid resistance is generally much larger than the air resistance, so when the cleaning brush 242 is to be used for cleaning, the liquid storage space 13 It is preferred to maintain a high liquid level. In addition, as can be seen from the foregoing relationship, when θ1 is closer to 90° and r1 is longer, the first resistance F1 can be converted into a larger torque to drive the cleaning element 24 to rotate, and the cleaning brush 242 is pressed against the peripheral wall 11 Strengthen the cleaning effect. In addition to the cleaning brush 242, the ball brush 26 can also be used to scrub the wall surface when the spindle 21 is rotated; as shown in Fig. 6, when the liquid storage space 13 stores water or other liquid, the ball brush 26 can rotate along the water flow. The centrifugal force is applied to the peripheral wall 11 to cause the ball brush 26 to continuously rub the peripheral wall 11 to achieve a cleaning effect; as shown in FIG. 7, when the water or other liquid has been discharged from the liquid storage space 13, the ball brush 26 can be changed into a baffle plate. The unit 25 pushes and scrapes the bottom wall 12, thereby achieving the effect of cleaning the bottom wall 12.

Thereafter, as shown in Fig. 8, when the cleaning is completed and the driving device 22 stops acting, the fluid in the liquid storage space 13 continues to flow for a period of time due to inertia, so the flow resistance plate 241 is subjected to a reverse third resistance. F3, thereby causing the cleaning member 24 to be subjected to the opposite torsion to return to a state where the cleaning brush 242 is not in contact or not in contact with the peripheral wall 11, so that the cleaning brush 242 does not cause elastic fatigue due to continuous close contact with the peripheral wall 11. In other words, in the present invention, the cleaning brush 242 does not continue to abut against the peripheral wall 11 when the driving device 22 stops functioning. It will be appreciated that if the drive unit 22 ceases to function and there is still water in the reservoir space 13, the flow of water that has not stopped the vortex can cause a flushing action on the cleaning brush 242.

As shown in the first and second embodiments, in the first embodiment, in order to reduce the output load of the driving device 22, the baffle 251 may be provided with a plurality of perforations for allowing water such as water and air to pass but not for the ball brush 26 to pass. 252, thereby reducing the flow resistance of the baffle 251 when it is rotated, and reducing the workload of the driving device 22.

As shown in the first and second embodiments, in the first embodiment, in order to facilitate the discharge of the clean waste water, the bottom wall 12 may have a drain passage 121, and the inside of the main shaft 21 defines a drain passage 211 communicating with the drain passage 121. The main shaft 21 is adjacent to the bottom wall 12 and can be provided with at least one drainage hole 212 to communicate with the drainage channel 211 and the liquid storage space 13, so that the cleaning wastewater in the liquid storage space 13 can be sequentially drained through the drainage hole 212. The water flow path 211 and the water discharge channel 121 are discharged to the outside. In order to control the drainage action, the cylinder 10 may further have a drain valve 121 provided in the bottom wall 12 of the drain valve 17, which can be drained when the drain valve 17 is opened, and not drained when the drain valve 17 is closed. .

As shown in the first and second embodiments, in the first embodiment, water or cleaning liquid may be replenished into the liquid storage space 13 during cleaning. At this time, the cleaning member 24 further has a pipe joint 27 pivoted to the main shaft 21 The pipe joint 27 is connected to a water supply pipe 271. The inside of the main shaft 21 further defines a flushing flow path 213. The flushing flow path 213 and the water discharge flow path 211 are not in communication with each other, and the main shaft 21 has a corresponding one. The water supply hole 214 of the water supply port 214 is connected to the flushing flow path 213, so that the water or cleaning liquid supplied from the water supply hole 214 can enter the flushing flow path 213; in addition, the support 23 can have at least one flushing pipe connected to the flushing flow path 213. The flushing tube may be the upper bracket 231 itself (as shown in the embodiment), or may be an additional tube body, the flushing tube has a water outlet 2311 adjacent to the peripheral wall 11, thereby the cleaning brush 242 and the ball brush. 26 When the cylinder 10 is cleaned, water or cleaning liquid can be continuously supplied through the water supply pipe 271, the pipe joint 27, the water supply hole 214, the flushing flow path 213, the flushing pipe and the water outlet 2311, thereby rinsing the cleaning brush 242 and the ball brush 26 And take away the impurities scraped by both.

It should be noted that since the cleaning element 24 and the ball brush 26 can independently function independently, as long as any one of them can be used for cleaning purposes, in the third embodiment shown in FIG. The cleaning device 20 includes only the cleaning member 24 and does not include the shutter unit 25 and the ball brush 26, and the peripheral wall 11 can be cleaned by the cleaning brush 242 alone. In addition, the number of cleaning elements 24 can be increased or decreased as needed, for example, using one or More cleaning elements 24; or, in the fourth embodiment shown in Fig. 10, the cleaning device 20 includes only the shutter unit 25 and the ball brush 26 without including the cleaning member 24, and thus can be separately provided by the ball brush 26 The peripheral wall 11 and the bottom wall 12 are cleaned.

It should be noted that the design of the cleaning element 24 can be changed according to requirements. For example, in the fifth embodiment shown in FIG. 11, a plurality of axially adjacent axial axes are provided on the same pivot axis X. The cleaning elements 24a, 24b, and 24c, each of which can independently rotate. In addition, the shape of the flow resistance plate 241 can also be changed. For example, in the sixth embodiment shown in FIG. 12, the flow resistance plate 241 has an upper end 2411, and the flow resistance plate 241 is closer to the upper end 2411. The shorter the distance from the peripheral wall 11 is, the more the liquid in the liquid storage space 13 is vortexed in the cylinder, and a water gap is easily generated in the center of the liquid storage space 13 (the dotted line in the figure indicates The liquid level when the fluid vortex is high, so the moderate arcing design of the flow resistance plate 241 can increase the draft area, thereby increasing the torsion generated by the flow resistance.

In view of the above, the liquid storage device with the cleaning device of the present invention can not only facilitate the automatic cleaning operation, but also can greatly delay the elastic fatigue of the cleaning brush or the ball brush, and increase the service life of the cleaning device, thereby realizing the purpose of the novel. .

Finally, it must be stated that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the novel, and other equivalent substitutes or variations should also be applied for the present invention.
