Referring to fig. 3-7, a bi-directional motor 11 (bi-directional motor 11 is a motor capable of achieving forward and reverse rotation, and is an existing driving device) is fixedly installed in a housing 1, a rotating shaft (not shown in the drawing, but seen in fig. 7) is fixedly installed at a driving end of bi-directional motor 11, the rotating shaft penetrates through and is rotatably installed on housing 1, a plunger 19 is fixedly installed on the rotating shaft, a protruding block 20 is fixedly installed on plunger 19, a connecting shaft 21 is fixedly installed on protruding block 20, a connecting head 16 is rotatably installed on connecting shaft 21, and a pressing wheel 22 is fixedly installed on connecting head 16, when bi-directional motor 11 starts to operate, through cooperation of the rotating shaft, plunger 19, protruding block 20 and connecting shaft 21, the pressing wheel 22 is driven by connecting head 16 to perform eccentric motion (relative to the rotating shaft).
Referring to fig. 1, 2, and 4-10, a cover 2 is fixedly mounted on a housing 1, a limiting ring 18 is fixedly mounted in the cover 2, a plurality of fixed cylinders 23 are fixedly mounted on the limiting ring 18, springs 25 are fixedly mounted in the fixed cylinders 23, an arc pressing plate 24 is fixedly mounted between the springs 25, an extrusion hose 17 is fixedly mounted on the arc pressing plate 24, two input heads 5 are penetrated and fixedly mounted on the cover 2, one ends of the two input heads 5 penetrate and are fixedly mounted on the limiting ring 18 and the arc pressing plate 24, one end of the extrusion hose 17 is fixedly communicated with the input head 5 located above, and the other end of the extrusion hose 17 is fixedly communicated with the input head 5 located below (as shown in the direction of fig. 7, the extrusion hose 17 is communicated with the input head 5 above and is a water inlet end, and the other end is communicated with the input head 5 below).
When the device is placed at the sampling point, the input tube 9 can be taken out from the housing 1, the filter rod 10 is inserted into the input head 5 above, and the outer diameter of the filter rod 10 is slightly smaller than the inner diameter of the water inlet of the input head 5 above, so that the filter rod 10 can be tightly inserted into the input head 5 above (in the direction shown in fig. 5), and the connection stability of the filter rod 10 and the corresponding input head 5 in the subsequent water delivery process can be effectively improved.
When the filter rod 10 is stably placed in the corresponding input head 5, the bidirectional motor 11 is started, so that the extrusion wheel 22 performs eccentric motion to extrude the extrusion hose 17, the hose at the position is compressed at this time, water at the front of the rotation direction of the extrusion wheel 22 is pushed (as the extrusion hose 17 is a reference object in fig. 7, the rotation direction of the extrusion wheel 22 is clockwise rotation under force), and after the extrusion wheel 22 continuously rotates to release extrusion of the part of hose, negative pressure is generated in the part of hose at this time, and water outside the extrusion hose 17 is sucked into the part of hose, so that the pumping effect is achieved (similar to the pumping principle of the existing peristaltic pump).
The two ends of the extrusion hose 17, which are communicated with the two input heads 5, are made of hard materials, the rest is made of soft materials (and pipe body parts made of hard materials are all installed inside the corresponding input heads 5 so as to prevent the extrusion wheel 22 from eccentrically moving to press the extrusion hose 17, and the pipe body of the hard part is used for obstructing the rotation of the extrusion wheel 22), and the extrusion hose 17 is integrally a spiral pipe, when the hard pipe bodies at the two ends of the extrusion hose 17 are removed, the two ends of the extrusion hose 17 are combined at the moment, so that a closed-loop annular pipe is formed, the closed-loop annular pipe coincides with the rotating path of the extrusion wheel 22, and the effect that the extrusion wheel 22 continuously presses the extrusion hose 17 in the rotating process can be realized.
Meanwhile, as the extrusion wheel 22 performs eccentric motion to continuously extrude the extrusion hose 17, the continuity and stability of pumping water of the device can be effectively improved, namely when the extrusion wheel 22 rotates to extrude the water inlet end of the extrusion hose 17, water in front of the extrusion hose 17 in the rotation direction of the extrusion wheel 22 can be extruded from the water outlet end of the extrusion hose 17 through clockwise continuous rotation of the extrusion wheel 22, when the extrusion wheel 22 rotates to the water inlet end of the extrusion hose 17 again, water in the rear side of the extrusion wheel 22 in the rotation direction can be extruded at the moment, namely, the continuous and stable water delivery effect of the extrusion hose is realized (a plurality of indirect distribution rollers are usually arranged in the conventional peristaltic pump, the rollers push the water delivery pipe forwards at one moment, and release the pipe at the other moment, so that the water delivery pipe is restored to the original state, intermittent pressure fluctuation is easy to generate in the process, thereby generating pulse flow, the stability of the water is reduced, the pulse can generate larger vibration, the activity of substances in the water is influenced, and the follow-up detection result is reduced.
Referring to fig. 4 to 7 and 9, the outer ring gear 14 is fixedly installed on the pressing wheel 22, and the inner gear ring 13 engaged with the outer ring gear 14 is fixedly installed on the limiting ring 18.
When the extrusion wheel 22 drives the outer toothed ring 14 to rotate together, the force generated by the engagement of the rotation of the outer toothed ring 14 and the inner toothed ring 13 can cause the extrusion wheel 22 to do circular motion with the connector 16 as a central shaft (the extrusion wheel 22 does circular motion on the surface of the extrusion hose 17, namely the extrusion wheel 22 rotates to extrude the extrusion hose 17), so that the friction force generated when the extrusion hose 17 continuously contacts and breaks away from the extrusion wheel 22 in the extrusion process can be effectively reduced, the abrasion of the surface of the extrusion hose 17 in the use process (the force required by the circular motion of the roller on the axis of the roller in the conventional peristaltic pump is partially provided by the friction force generated when the roller is separated from the water delivery pipe with the extrusion hose 17), the service life of the extrusion hose 17 can be prolonged, and the service life of the extrusion hose 17 can be prolonged.
Meanwhile, the filter rod 10 can only filter the extracted water to a certain extent, the condition that the water pipe body is blocked can be effectively prevented, but the extracted water cannot be completely filtered, when the extracted water contains hard impurities such as small stones and the like and flows into the extrusion hose 17 along the input pipe 9 and the upper input head 5 (in the direction shown in fig. 6), when the extrusion wheel 22 extrudes the part of the extrusion hose 17 containing the small stones and the hard impurities, the extrusion force suffered by the small stones and the hard impurities can be transmitted to the arc-shaped pressing plate 24 through the extrusion hose 17 (when the inside of the extrusion hose 17 is free of impurities or has no obvious impurities, at the moment, the extrusion wheel 22 can deform when the extrusion hose 17 is pressed by the extrusion wheel 22, the corresponding springs 25 are extruded by the arc-shaped pressing plate 24, so that an effective buffer effect can be achieved, and after the extrusion wheel 22 rotates away from the point, the small stones and the hard impurities in the extrusion hose 17 can flow out of the extrusion hose 17 along with the hard impurities, and continue to flow from the extrusion hose 17.
Referring to fig. 1, a protection cover (drawn in the figure but not marked, and seen from fig. 1) is mounted on the cover body 2 in a clamping manner, so that a protection effect can be achieved to a certain extent on components mounted inside the cover body 2 through the protection cover, the damage to each component inside the cover body 2 caused by dust in air and human factors can be effectively reduced, and meanwhile, maintenance and replacement of each component inside the cover body 2 can be facilitated by a connection mode between the protection cover and the cover body 2, which is convenient for maintenance personnel.
Meanwhile, the protective cover is made of transparent materials, such as Polyethylene (PE) materials, and the operation condition of each component in the cover body 2 can be conveniently observed in real time by the aid of good transparency and durability of the PE materials.
Referring to fig. 1-4, a radiator 6 is fixedly installed on a housing 1 (the working principle of the radiator 6 is that heat is transferred from an object generating heat to the surrounding environment by using heat conduction and convection so as to reduce the temperature of the object), a dust cover (not shown in the figure) is fixedly installed on the radiator 6, when the device starts pumping water, the radiator 6 is started, the radiator 6 can realize heat dissipation treatment on the heat generated when an electric appliance (namely, a bidirectional motor 11) in the housing 1 runs, the service performance of the electric appliance after continuous use can be improved, meanwhile, dust and other impurities in the air can be effectively reduced to enter the radiator 6 through the dust cover, and damage to internal components of the radiator 6 occurs.
Referring to fig. 1,3 and 4, a display screen (not shown) is fixedly installed on the casing 1, a control knob 4 is installed on the casing 1, starting and closing of the bi-directional motor 11 can be achieved by rotating the control knob 4 (when the control knob 4 is driven by manpower to start rotating, signals for rotating the control knob 4 are transmitted through existing middleware such as a sensor, and the bi-directional motor 11 is controlled to operate, which is the prior art and is not further described herein), so that a inspector can conveniently operate according to a required control device.
Referring to fig. 1, 3-6, an output tube 3 (direction shown in fig. 6) is fixedly connected to the lower input head 5, the output tube 3 penetrates through and is fixedly mounted on the housing 1, a telescopic hose 12 is fixedly connected to the output tube 3, a cannula 15 is fixedly connected to the telescopic hose 12, before pumping water starts, after the collection bottle 8 is placed inside the housing 1, one end of the cannula 15 can be manually inserted into the anti-overflow cover (direction shown in fig. 6, through tip design below the cannula 15, the cannula 15 can be conveniently and better inserted into the anti-overflow cover, meanwhile, a through hole matched with the cannula 15 is formed in the anti-overflow cover, the shape of the through hole is small and large, and is matched with the shape of the cannula 15, so that stability of the cannula 15 and the relative position of the cannula 15 after the cannula 15 is inserted into the anti-overflow cover can be effectively improved, and meanwhile, the upper end of the cannula 15 is required to be ensured to be positioned outside the anti-overflow cover (shown in fig. 3), so that the cannula 15 can be conveniently and better pulled out.
Meanwhile, after sampling is finished, the operation of the bidirectional motor 11 can be stopped through the control knob 4, then an upward pulling force (in the direction shown in fig. 3) is manually applied to the cannula 15, and the cannula 15 compresses the telescopic hose 12 until the cannula 15 is taken out of the anti-overflow cover, so that the collection bottle 8 can be taken out of the shell 1 later.
The specific working principle of the invention is as follows:
Firstly, the collecting bottle 8 is placed stably in the shell 1, after the insertion tube 15 is inserted into the anti-overflow cover, the input tube 9 and the filter rod 10 are taken out from the shell 1, the filter rod 10 is inserted into the water inlet end of the input head 5, after the filter rod 10 is installed in the input head 5, one end of the input tube 9 can be placed in water, the bidirectional motor 11 is started through the control knob 4 to start extracting water at the position where the detection point is located, in the operation process of the bidirectional motor 11, the connector 16 drives the extrusion wheel 22 to perform eccentric motion through the cooperation of the insertion rod 19, the convex block 20 and the connecting shaft 21, the extrusion wheel 22 presses the extrusion hose 17 in the operation process, and the effect that water is input into the collecting bottle 8 through the cooperation of the input tube 9, the input head 5 and the extrusion hose 17 can be realized through the output tube 3 and the insertion tube 15 is realized.
Meanwhile, in the process that the extrusion wheel 22 eccentrically moves to press the extrusion hose 17, the continuous extrusion effect of the extrusion hose 17 can be achieved, namely when the extrusion wheel 22 rotates to press the water inlet end of the extrusion hose 17, the hose at the position can be extruded, the extrusion wheel 22 continuously rotates to push water in the front of the rotation direction of the extrusion wheel 22 and the extrusion hose 17 until the water is extruded from the extrusion hose 17, when the extrusion wheel 22 rotates the water inlet end of the extrusion hose 17 again, the extrusion wheel 22 can push water at the rear side of the original rotation direction of the extrusion wheel 22 at the moment, the effect that the extrusion wheel 22 continuously presses the extrusion hose 17 can be achieved, the phenomenon that the device pulses in the water taking process can be effectively reduced, and the continuity and stability of the device are improved.
Meanwhile, in the process of rotating the extrusion wheel 22, the outer toothed ring 14 can rotate on the inner toothed ring 13, and at the moment, the force generated by the meshing between the outer toothed ring 14 and the inner toothed ring 13 can indirectly provide kinetic energy for the extrusion wheel 22 to do circular motion with the axis of the extrusion wheel, so that the extrusion wheel 22 can roll on the surface of the extrusion hose 17 to extrude the extrusion hose 17, the friction force generated between the extrusion wheel 22 and the extrusion hose 17 is effectively reduced, and the service life of the extrusion hose 17 is prolonged.
And because filter rod 10 can filter the extraction water, but can not realize the complete filtration to impurity, when less stone and hard impurity in rivers get into extrusion hose 17 inside along input tube 9 and top input head 5 (as shown in the direction of fig. 6), extrusion wheel 22 rotates and extrudes the hard impurity position department such as containing less stone to extrusion hose 17, and less hard impurity such as stone can apply the extrusion force to arc butt clamp 24 through extrusion hose 17 this moment, and arc butt clamp 24 can extrude corresponding spring 25 this moment, produces the buffering effect to extrusion hose 17, can further improve extrusion hose 17's life.
Finally, after the sampling is completed, the bidirectional motor 11 is closed through the control knob 4, then the insertion tube 15 is pulled out of the collecting bottle 8 through the rotation door body 7, the collecting bottle 8 can be taken out of the shell 1, and the obtained sample is detected by the existing detection device.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
