Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a river bank protection and repairing device. Background Art

[0002] In today's water conservancy projects and ecological environment maintenance, the stability and health of river slope protection are of vital importance. River slope protection not only bears the heavy responsibility of protecting the river bank soil from erosion by water flow, but also is the key line of defense to maintain the balance of the river ecosystem and ensure the water quality of the river. However, for a long time, many factors have caused river slope protection to face severe challenges and damage, and efficient repair methods are urgently needed.

[0003] On the one hand, the continuous action of natural factors has caused significant damage to the river bank protection. Seasonal rainstorms and floods, with their powerful impact force, repeatedly impact the surface of the bank protection, taking away a large amount of bank protection soil and vegetation roots, and weakening the overall structural strength of the bank protection. At the same time, the frequent fluctuations in the river water level have caused the bank protection to be in a harsh environment of alternating dry and wet conditions for a long time, accelerating the weathering and peeling process of the bank protection materials, resulting in cracks and collapse of the bank protection.

[0004] On the other hand, the interference of human activities has also brought heavy pressure to the river bank protection. The illegal discharge of industrial wastewater and domestic sewage has caused the water quality of the river to deteriorate, and the harmful substances in the water have corroded the bank protection materials and reduced their durability. In addition, unreasonable construction and development along the river and navigation disturbances by shipping vessels have damaged the integrity of the bank protection to varying degrees.

[0005] In order to deal with these problems, river slope protection and repair devices came into being. Among the many repair processes, the irrigation and maintenance of slope protection vegetation is the core link to ensure the repair effect and promote vegetation growth. Traditional irrigation devices often take water directly from the river, but due to the complex water body of the river, it contains a large amount of floating objects, silt and other impurities, which can easily cause the pumping port to be blocked during the pumping process. In particular, the grille plate set at the front end of the pumping port is used to initially filter out larger impurities to prevent them from entering the pumping system and damaging equipment such as water pumps, but it is often blocked due to the accumulation of impurities. Once the grille plate is blocked, not only will the pumping efficiency drop sharply, but it may even cause the entire irrigation mechanism to fail to operate normally, delaying the slope protection repair process and increasing the repair cost.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example, see Figure 1-Figure 8 A river slope protection repair device includes an irrigation mechanism 100, the irrigation mechanism 100 includes a water pump 140, the water pump 140 is connected to a T-tube and a water outlet pipe 110, the water outlet pipe 110 is provided with a plurality of branch pipes 120, the branch pipes 120 are placed on the river slope, a plurality of nozzles 130 are provided on the branch pipes 120, the plurality of nozzles 130 are all provided with solenoid valves 131, and a plurality of humidity sensors corresponding to the plurality of solenoid valves 131 are provided on the river slope; the two sections of the T-tube away from the water pump 140 are respectively a first pumping pipe 210 and a second pumping pipe 440, the first pumping pipe 210 is connected to a first pumping cylinder 230 through a vertical pipe 220, and is connected to a second pumping cylinder 260 through a connecting pipe 211 and an L-shaped pipe 212, and the second pumping pipe 440 is connected to a neutralizing cylinder 420 is connected, and a first pH value meter 431 is provided at the water inlet of the neutralization mechanism 400; a first three-way valve is provided at the connection between the vertical section and the horizontal section of the T-tube, and the first pumping pipe 210 and the second pumping pipe 440 are located on both sides of the first three-way valve on the horizontal section respectively. When the first pH value meter 431 detects that the river water is not neutral, the first three-way valve operates to connect the neutralization mechanism 400 with the water pump 140, and, when the first pH value meter 431 detects that the river water is neutral, the first three-way valve operates to connect the water diversion mechanism 200 with the water pump 140; when any humidity sensor detects that the soil moisture decreases, the corresponding solenoid valve 131 is opened, and the water pump 140 is operated, and when the number of solenoid valves 131 opened increases, the operating speed of the water pump 140 increases.

[0032] The outlet pipe 110 is placed at the bottom of the river slope, and the multiple branch pipes 120 are placed on the river slope protection. The spacing between the multiple branch pipes 120 is adjusted so that the multiple nozzles 130 can fully cover the river slope protection. Humidity sensors are installed on the slope protection near the nozzles 130. The number of humidity sensors can be adaptively set according to their detection range. One humidity sensor can correspond to a solenoid valve 131 on one nozzle 130, or one humidity sensor can control multiple solenoid valves 131 close to each other. The maximum number of humidity sensors is equal to the number of solenoid valves 131.

[0033] When the humidity sensor detects that the soil humidity has dropped, the control system controls the corresponding solenoid valve 131 to open according to the signal of the humidity sensor, and at the same time the water pump 140 runs, extracting water from the river channel and spraying it through the opened nozzle 130 to irrigate and repair the slope protection in the dry part;

[0034] Before the water pump 140 extracts river water, the first pH value measuring instrument 431 is always in operation, and the control system always receives the acidity and alkalinity of the river water detected by the first pH value measuring instrument 431. When the river water is close to neutral, the river water at this time can be used to irrigate and repair the slope protection without neutralization operation. In this case, the control system controls the operation of the first three-way valve to connect the water diversion mechanism 200 with the water pump 140. At this time, the water pump 140 extracts river water through the water diversion mechanism 200 and uses it to irrigate the slope protection;

[0035] When the control system receives the river water detected by the first pH value measuring instrument 431, which is not neutral and has a high pH value, the river water at this time needs to be neutralized before being used to irrigate the slope protection. In this state, the control system controls the operation of the first three-way valve to connect the neutralization mechanism 400 with the water pump 140. The river water at this time is first adjusted to a pH value by the neutralization mechanism 400 before being used to irrigate the slope protection, thereby avoiding the situation where the slope protection is irrigated with acidic or alkaline river water and causes a large amount of damage to vegetation;

[0036] The first three-way valve is electromagnetically controlled, and its operating principle is the same as that of the electromagnetic valve 131. In addition, if the number of electromagnetic valves 131 opened increases, it means that the slope protection needs more water for irrigation. At this time, the control system controls the operation speed of the water pump 140 to increase, thereby increasing the pumping and discharge volume of the river water, so that when the required irrigation range increases, there will be enough water to irrigate and repair the slope protection;

[0037] It should also be noted that the neutralization mechanism 400 can be determined whether to be installed according to the river conditions. If the probability of pH imbalance in river water is low or will not occur, only the irrigation mechanism 100, water diversion mechanism 200 and first dredging mechanism 300 provided in this embodiment are required.

[0038] The water diversion mechanism 200 includes a vertical pipe 220, one end of which is connected to the first water pumping pipe 210, and the other end is connected to the first water pumping cylinder 230. The port of the first water pumping cylinder 230 is connected to a grid plate 240. The first water pumping cylinder 230 floats on the water surface, and the grid plate 240 is immersed under the water surface.

[0039] The density of the first pumping cylinder 230 is less than that of the river water, and the density of the grid plate 240 is greater than that of the river water, so that one end of the first pumping cylinder 230 that is located on the grid plate 240 can be immersed below the surface of the river water. Since the grid plate 240 is located at the water suction port of the first pumping cylinder 230, the water suction port of the first pumping cylinder 230 is immersed below the surface of the river water, thereby preventing floating objects on the surface of the river water from gathering at the grid plate 240.

[0040] The first dredging mechanism 300 is connected to the water diversion mechanism 200. The first dredging mechanism 300 includes a first piston cylinder 310. The first piston cylinder 310 is connected to the end of the first water pumping pipe 210. A piston plate 320 is slidably connected in the first piston cylinder 310. A first piston rod 330 is connected to the piston plate 320. The first piston rod 330 is slidably connected to the first water pumping pipe 210, and the side wall of the first piston rod 330 is in contact with the inner wall of the first water pumping pipe 210. The first piston cylinder 310 is connected to an extraction pipe 311 and a discharge pipe 312. Both the pipe 311 and the discharge pipe 312 are provided with a one-way valve. The end of the extraction pipe 311 is immersed under the water surface, and the end of the discharge pipe 312 passes through the first pumping cylinder 230 and the end faces the upper surface of the grid plate 240. The river water enters the first pumping cylinder 230 from the lower surface of the grid plate 240. When the grid plate 240 is blocked, the negative pressure generated by the water pump 140 attracts the first piston rod 330 to slide into the first pumping pipe 210, so that the piston plate 320 slides, so that the water in the first piston cylinder 310 is rebounded to the grid plate 240 through the discharge pipe 312.

[0041] The first piston cylinder 310 and the second piston cylinder 380 are connected to the two limit frames 250 through two L-shaped frames 251 respectively. The setting of the first dredging mechanism 300 clears the blockage of the grid plate 240. When the water diversion mechanism 200 pumps water from the river, debris below the river surface, such as water plants or objects with a density not less than that of the river water, blocks the grid plate 240. At this time, the negative pressure in the first pumping pipe 210 increases, so that the negative pressure adsorbs the first piston rod 330, so that the first piston rod 330 drives the active The plug plate 320 slides, so that the piston plate 320 pushes the water in the first piston cylinder 310 to the upper part of the grid plate 240 through the discharge pipe 312, and recoils the grid plate 240, thereby clearing the grid plate 240. It should also be noted that when the first piston rod 330 slides to its maximum stroke, it will not move to the connection between the vertical pipe 220 and the first pumping pipe 210, thereby ensuring that the river water can continue to flow through the vertical pipe 220 into the first pumping pipe 210 after the subsequent grid plate 240 is cleared.

[0042] The first dredging mechanism 300 also includes a first tension spring 340 connected between the piston plate 320 and the first piston cylinder 310. The piston plate 320 and the first piston cylinder 310 are magnetically attracted to each other at their ends near the first tension spring 340. After the negative pressure in the first pumping pipe 210 increases to exceed the magnetic attraction between the piston plate 320 and the first piston cylinder 310, the first piston rod 330 slides quickly to allow water discharged from the discharge pipe 312 to impact the grille plate 240; after the grille plate 240 is restored from a blocked state to a transparent state, the first tension spring 340 pulls the piston plate 320 to reset, so that the first piston cylinder 310 extracts river water through the extraction pipe 311.

[0043] There is a magnetic attraction between the piston plate 320 and the end of the first piston cylinder 310, and the two are connected by the first tension spring 340, so that the piston plate 320 can resist the negative pressure in the first pumping pipe 210, so that the piston plate 320 will not slide when the grid plate 240 is not blocked or the blockage is not serious. When the grid plate 240 is seriously blocked, the negative pressure in the first pumping pipe 210 increases. When the pressure of the negative pressure exceeds the magnetic attraction and the tension of the first tension spring 340, the negative pressure can be quickly released, so that the sliding speed of the piston plate 320 in the first piston cylinder 310 is accelerated, and the water discharged from the discharge pipe 312 can impact the grid plate 240, so that The grille plate 240 can be better unblocked. When the grille plate 240 is unblocked, the negative pressure in the first pumping pipe 210 is reduced. At this time, the first tension spring 340 pulls the piston plate 320 to reset, so that the first piston cylinder 310 slowly extracts the river water through the extraction pipe 311 to complete the replenishment. In addition, due to the slow extraction speed, the water at the end of the extraction pipe 311 is less disturbed, which reduces the probability of the extraction pipe 311 being blocked. In addition, the port of the extraction pipe 311 is far from the grille plate 240 in the horizontal and vertical directions, thereby preventing the debris cleaned on the grille plate 240 from flowing to the port of the extraction pipe 311 and causing the extraction pipe 311 to be blocked.

[0044] The water diversion mechanism 200 also includes a second water pumping cylinder 260. The first water pumping pipe 210 is connected to a connecting pipe 211, and the connecting pipe 211 is connected to an L-shaped tube 212. The second water pumping cylinder 260 is connected to one of the ports of the L-shaped tube 212. After the first piston cylinder 310 discharges water into the first water pumping cylinder 230 and the negative pressure in the first water pumping pipe 210 is not reduced, the first water pumping pipe 210 is connected to the second water pumping cylinder 260.

[0045] In order to prevent the first water pump 230 from being seriously blocked and unable to be unblocked, a second water pump 260 is provided. When the first piston cylinder 310 drains water into the first water pump 230, unblocking work is performed. After drainage, if unblocking is completed, the negative pressure in the first water pump pipe 210 is reduced. At this time, the first water pump 230 continues to operate. Otherwise, the first water pump 230 stops operating and the second water pump 260 starts operating.

[0046] The first dredging mechanism 300 also includes a reversing pipe 350, a reversing hole 351 is opened on the side wall of the reversing pipe 350, and the reversing pipe 350 rotates within a range of ninety degrees on the first pumping pipe 210, and when the reversing pipe 350 rotates, it can be connected to the vertical pipe 220 or the connecting pipe 211.

[0047] The reversing pipe 350 is arranged at the connection position of the first pumping pipe 210, the vertical pipe 220 and the connecting pipe 211, and the axes of the three pipes intersect at one point. When the first pumping cylinder 230 can be unblocked, the reversing hole 351 is connected with the vertical pipe 220. At this time, the suction force generated by the water pump 140 is transmitted to the first pumping cylinder 230. If the first pumping cylinder 230 cannot be unblocked, the reversing pipe 350 rotates ninety degrees so that the reversing hole 351 is connected with the connecting pipe 211, so that the suction force generated by the water pump 140 is transmitted to the second pumping cylinder 260 through the first pumping pipe 210, the connecting pipe 211 and the L-shaped pipe 212. Therefore, when the first pumping cylinder 230 cannot be unblocked, it can still ensure that irrigation water is provided for the repair of the river bank slope.

[0048] The first dredging mechanism 300 also includes an insert rod 360 connected to the end of the first piston rod 330, and a slider 361 is connected to the insert rod 360. A spiral groove 362 is provided on the inner wall of the reversing tube 350. After the first piston rod 330 slides toward the reversing tube 350, the slider 361 can slide into the spiral groove 362 to rotate the reversing tube 350.

[0049] The diameter of the plug rod 360 is smaller than the inner diameter of the reversing tube 350, thereby preventing the plug rod 360 from being easily moved away from the reversing tube 350 due to the negative pressure. When the first pumping cylinder 230 can be unblocked, the first piston cylinder 310 drains water into the first pumping cylinder 230, which can quickly restore the grid plate 240 to be transparent. At this time, the negative pressure state in the first pumping tube 210 is quickly restored, so that the first piston rod 330 can be quickly reset. At this time, the first piston rod 330 will not slide to the reversing tube 350, or although the reversing tube 350 slides to the reversing tube 350, the resetting of the first piston rod 330 restores the reversing tube 350 to its original state.

[0050] In addition, if the first water pumping cylinder 230 cannot be unblocked, the grille plate 240 will not become transparent again after the first piston cylinder 310 drains water to the grille plate 240. At this time, the negative pressure state in the first water pumping pipe 210 will not disappear, so that the first piston rod 330 can move toward the reversing tube 350 to the maximum stroke distance. At this time, the slider 361 slides to its end in the spiral groove 362, driving the reversing tube 350 to rotate ninety degrees, thereby switching the working state of the first water pumping cylinder 230 and the second water pumping cylinder 260.

[0051] A magnetic ring 352 is connected to the side wall of the reversing tube 350 , and the magnetic ring 352 rotates on the inner wall of the first pumping pipe 210 . A plurality of magnetic blocks 353 are connected to the outer wall of the first pumping pipe 210 . When the reversing tube 350 rotates to an angle close to ninety degrees, the magnetic blocks 353 are magnetically attracted to the magnetic ring 352 .

[0052] The setting of the magnetic ring 352 enables the reversing tube 350 to complete positioning after rotating ninety degrees by relying on the magnetic attraction between it and the magnetic block 353, ensuring that the reversing tube 350 can maintain its state after rotating ninety degrees, thereby ensuring stable connection between the first pumping cylinder 230 and the water pump 140.

[0053] A latch 370 is inserted into the side wall of the first water pumping pipe 210, and a second tension spring is connected between the latch 370 and the outer wall of the first water pumping pipe 210. A positioning hole 371 that cooperates with the latch 370 is opened on the first piston rod 330. When the first piston rod 330 slides so that the slider 361 slides to the end of the spiral groove 362, the positioning hole 371 is located directly below the latch 370.

[0054] When the first piston rod 330 slides toward the reversing tube 350, so that the insertion rod 360 is inserted into the reversing tube 350, and the slider 361 slides to the end of the travel of the spiral groove 362, the positioning hole 371 on the side wall of the first piston rod 330 can be directly below the latch 370, so that the tension of the second tension spring can make the latch 370 inserted into the positioning hole 371, so that the first piston rod 330 cannot slide in the opposite direction at this time. At this time, the reversing tube 350 rotates ninety degrees and maintains its state, so that the water pump 140 and the second pumping cylinder 260 are stably connected. In addition, in order to ensure that the first piston rod 330 does not rotate on its own, a key and a keyway sliding fit can be set between the piston plate 320 and the first piston cylinder 310 for limiting.

[0055] The first dredging mechanism 300 also includes a second piston cylinder 380, which is connected to one end of the L-shaped tube 212 away from the second pumping cylinder 260. A piston plate 320 slides inside the second piston cylinder 380. The piston plate 320 located in the second piston cylinder 380 is connected to a second piston rod 381, and the second piston rod 381 slides inside the L-shaped tube 212.

[0056] The second piston cylinder 380 is provided to dredge the grid plate 240 on the second pumping cylinder 260. The dredging principle is the same as that of the first piston cylinder 310 for dredging the first pumping cylinder 230. In addition, the first dredging mechanism 300 of the device needs to be cleaned regularly to avoid blockage of both the first pumping cylinder 230 and the second pumping cylinder 260.

[0057] The coordinated arrangement of the water diversion mechanism 200 and the first dredging mechanism 300 greatly improves the stability of river water extraction and reduces the occurrence of poor irrigation effects due to blockage.

[0058] The neutralization mechanism 400 includes a mounting frame 410 , to which two limiting frames 250 are connected, and the first pumping cylinder 230 and the second pumping cylinder 260 vertically slide on the two limiting frames 250 , respectively.

[0059] The limiting frame 250 limits the positions of the first pumping cylinder 230 and the second pumping cylinder 260 to prevent them from floating to other positions in the river channel, thereby reducing the probability of the grid plate 240 being blocked. At the same time, the first pumping cylinder 230 and the second pumping cylinder 260 can slide vertically on the corresponding limiting frame 250, thereby preventing the first pumping cylinder 230 and the second pumping cylinder 260 from being separated from the river water due to the rise and fall of the water level in the river channel.

[0060] The neutralization mechanism 400 also includes a neutralization cylinder 420 connected to the mounting frame 410 , a second water pumping pipe 440 is connected to the neutralization cylinder 420 , a water inlet pipe 430 is connected to the neutralization cylinder 420 , a one-way valve is provided on the water inlet pipe 430 , and a first pH value meter 431 is connected to the water inlet pipe 430 .

[0061] When the river water needs to be neutralized and then irrigated, the water pump 140 is connected to the neutralization cylinder 420. At this time, the water pump 140 applies negative pressure to the inside of the neutralization cylinder 420, and the negative pressure is transmitted to the water inlet pipe 430, so that the river water enters the neutralization cylinder 420 through the water inlet pipe 430. Then the water pump 140 pumps the water in the neutralization cylinder 420 out, and a one-way valve is provided on the water inlet pipe 430, so that the river water can only flow into the neutralization cylinder 420 through the water inlet pipe 430, and the water in the neutralization cylinder 420 will not flow out into the river through the water inlet pipe 430, thereby preventing the neutralizing agent in the neutralization cylinder 420 from entering the river and causing a negative impact on the river environment.

[0062] The neutralization mechanism 400 also includes a stirring frame 460 rotating in the neutralization cylinder 420, a dual-axis motor 450 is connected to the mounting frame 410, one of the output ends of the dual-axis motor 450 is connected to a driving wheel 451, the rotating shaft of the stirring frame 460 passes through the neutralization cylinder 420 and the mounting frame 410 and is connected to a driven wheel 452, and a belt 453 is connected between the driving wheel 451 and the driven wheel 452; the other output end of the dual-axis motor 450 is connected to a filling pump 470, and the filling pump 470 is connected to a first pipeline 471 and a second pipeline 472, the first pipeline 471 is connected to an external liquid neutralization agent supply, the second pipeline 472 is connected to the neutralization cylinder 420, and a one-way valve is provided on the second pipeline 472, when the first pH value meter 431 detects that the pH value of the river water is high, the speed of the dual-axis motor 450 increases, thereby increasing the speed of the stirring frame 460 and increasing the speed of the filling pump 470 filling the liquid neutralization agent into the neutralization cylinder 420.

[0063] When the control system detects that the neutralization mechanism 400 is connected to the water pump 140, the dual-axis motor 450 operates synchronously. At this time, the dual-axis motor 450 drives the filling pump 470 to operate, extracts the external neutralizing agent and injects it into the neutralization cylinder 420. The dual-axis motor 450 also drives the stirring rack 460 to operate, so that the river water and the liquid neutralizing agent are quickly mixed. Moreover, when the first pH value measuring instrument 431 detects that the pH value is high, the speed of the dual-axis motor 450 increases, so that the addition flow of the neutralizing agent increases. At the same time, the speed of the stirring rack 460 increases, so that a large amount of neutralizing agent can be quickly mixed with the river water. A one-way valve can also be set on the second pipeline 472, so that the river water in the neutralization cylinder 420 will not flow back to the external supply place;

[0064] The neutralizing agent can be made of flash-soluble potassium dihydrogen phosphate powder and water. Potassium dihydrogen phosphate can neutralize both acidic and alkaline river water, and can also form a buffer between acidity and alkalinity to avoid excessive pH adjustment. Potassium dihydrogen phosphate contains phosphorus and potassium elements, and is suitable for slope protection plants that have a certain tolerance to phosphorus and potassium fertilizers, such as Bermuda grass and tall fescue.

[0065] A second pH value meter is also provided on the second pumping pipe 440, and the second pH value meter can re-detect the pH value of the river water in the neutralization cylinder 420. At the same time, a pipeline (not shown in the figure) can also be provided between the water pump 140 and the neutralization cylinder 420. An electric control valve is provided on the pipeline and the outlet pipe 110. If the second pH value meter detects that the river water flowing through the second pumping pipe 440 has not reached neutrality after treatment, the control system controls the electric control valve on the outlet pipe 110 to close, and the electric control valve on the pipeline to open, so that the river water in the neutralization cylinder 420 flows back to the neutralization cylinder 420 through the second pumping pipe 440, the water pump 140 and the pipeline, and the pH value thereof is continuously adjusted until the second pH value meter detects that the treated river water is neutral, and then the control system controls the electric control valve on the outlet pipe 110 to open, and the electric control valve on the pipeline to close, and the treated river water is used for irrigating the slope protection;

[0066] In addition, the dual-axis motor 450 does not run continuously. When the second pH value measuring instrument detects that the river water is close to neutral, the dual-axis motor 450 stops running. Otherwise, the dual-axis motor 450 continues to run.

[0067] An alarm 480 is also provided on the mounting frame 410. When the dual-axis motor 450 is running, the control system controls the alarm 480 to operate and sound an alarm, informing personnel that the river water is not suitable for watering crops or other purposes. The alarm 480 can also be connected to the network. When the alarm 480 is running, it transmits a signal to the remote terminal to remind the staff that the river water is polluted and that subsequent remedial measures need to be taken.

[0068] A second dredging mechanism 500 is provided on the neutralization mechanism 400, and the second dredging mechanism 500 includes a semicircular seat 510 rotated on the mounting frame 410, and an L-shaped rod 520 is connected to the semicircular seat 510. When the driven wheel 452 rotates, the semicircular seat 510 is driven to slide back and forth, so that the L-shaped rod 520 sweeps across the port of the water inlet pipe 430.

[0069] The second clearing mechanism 500 cleans the port of the water inlet pipe 430 to prevent the water inlet pipe 430 from being blocked. When the stirring frame 460 rotates, the driven wheel 452 drives the L-shaped rod 520 to swing back and forth, so that the L-shaped rod 520 repeatedly sweeps the port of the water inlet pipe 430, so that the debris that may accumulate at the port of the water inlet pipe 430 is cleaned.

[0070] The second dredging mechanism 500 also includes a mounting rod 540 coaxially connected to the driven wheel 452, a connecting rod 550 is connected to the side wall of the mounting rod 540, a lever 560 is hinged at the end of the connecting rod 550, a torsion spring 580 is sleeved on the hinge shaft 570 of the lever 560, and the two ends of the torsion spring 580 are respectively connected to the hinge shaft 570 and the connecting rod 550, a blocking rod 530 is connected to the semicircular seat 510, and when the driven wheel 452 rotates, the lever 560 pushes the semicircular seat 510 to slide through the blocking rod 530.

[0071] When the driven wheel 452 rotates, it drives the connecting rod 550 to swing synchronously. At this time, the connecting rod 550 drives the lever 560 to push the blocking rod 530 to make the semicircular seat 510 slide. When the semicircular seat 510 slides to the end of the stroke, the blocking rod 530 no longer moves. At this time, the lever 560 overcomes the torsion force of the torsion spring 580 and swings relative to the connecting rod 550, so that the lever 560 passes the position of the blocking rod 530 to avoid interference with the rotation of the driven wheel 452.

[0072] Two cross bars 590 are symmetrically connected to the mounting frame 410 on both sides of the semicircular seat 510 , and elastic ropes 591 are connected to both ends of the two cross bars 590 and the semicircular seat 510 .

[0073] The two elastic ropes 591 pull the two sides of the semicircular seat 510, so that the semicircular seat 510 is quickly reset, and after the semicircular seat 510 is reset, the L-shaped rod 520 is on one side of the water inlet pipe 430, so that when the semicircular seat 510 is pushed subsequently, the L-shaped rod 520 can completely sweep the lower part of the water inlet pipe 430.

[0074] The device as a whole can be powered by solar energy or mains electricity.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
