DETAILED DESCRIPTION

[0030] The following description is provided to enable any person skilled in the art to practice the application. The preferred embodiments described below are only examples of the application and other obvious variants can be conceived by those skilled in the art.

[0031] As Figures 1 to 9 ​The anti-corrosion water pump with anti-blocking function for pumping irrigation water shown comprises a bottom shell 1, the top of the bottom shell 1 is fixedly connected with a servo motor 3 and a water pump body 2 at both ends respectively, the inside of the bottom shell 1 is provided with a water bin 33, the water bin 33 is slidably connected with a blocking slide plate 18, the top of one end of the bottom shell 1 is further provided with a fixed ring 4 for blowing air to the servo motor 3, the air inlet end of the fixed ring 4 in the process of blowing air to the servo motor 3 is in communication with the space above the blocking slide plate 18, one side of the bottom of the water bin 33 is communicated with a communication pipe 9 for flushing the water pump body 2, the water inlet end and the water outlet end of the water pump body 2 are respectively communicated with a water inlet pipe 7 and a water outlet pipe 6, the communication pipe 9 is communicated with the water outlet pipe 6, and the end of the water inlet pipe 7 away from the water pump body 2 is provided with an anti-blocking assembly.

[0032] The inside of the water pump body 2, the water outlet pipe 6 and the water inlet pipe 7 is provided with an anti-corrosion coating.

[0033] The output shaft of the servo motor 3 is fixedly connected with the rotating shaft of the water pump body 2, and the servo motor 3 is used for providing power to the water pump body 2. This technology is well known to those skilled in the pump field, and will not be disclosed here.

[0034] In specific implementation, first, before pumping irrigation water, water is supplied to the water bin 33, and the water pressure makes the blocking slide plate 18 in the water bin 33 be lifted up, which can increase the weight of the bottom shell 1, reduce the vibration amplitude of the servo motor 3 and the water pump body 2 in the working process by increasing the weight, so as to achieve the purpose of shock absorption, and also can pump out the water in the water bin 33 through the communication pipe 9 after the irrigation is completed, so as to clean the water pump body 2 and the water inlet pipe 7, which is beneficial to avoid the case that the water pumped by the water pump body 2 contains impurities or microorganisms to corrode the water pump body 2 and the water inlet pipe 7.

[0035] It should be noted that if the water pump body 2 contains microorganisms, the microorganisms will corrode the water pump body 2 after breeding in the water pump body 2, and the microorganisms mainly live in dead water, so if there is residual irrigation water in the water pump body 2, the microorganisms will breed in the water pump body 2.

[0036] In the process of working of the servo motor 3, the fixed ring 4 is used to blow air to the servo motor 3, so as to reduce the heat generated by the servo motor 3 in the working process, realize the cooling of the servo motor 3, and avoid the overheat of the servo motor 3 due to long time working during the irrigation. In the process of heat dissipation, the gas flowing out of the fixed ring 4 will first pass through the space above the blocking slide plate 18, and then flow out through the fixed ring 4, and the heat generated at the bottom of the servo motor 3 will be conducted to the top wall plate of the bottom shell 1, and through the circulation of air flow, the bottom of the servo motor 3 can also be assisted to a certain extent.

[0037] After the servo motor 3 is started, the water pump body 2 is driven by the output shaft of the servo motor 3 to pump water for irrigation, and the water flow enters the water pump body 2 through the water inlet pipe 7 and then flows out through the water outlet pipe 6, so that the water flow is delivered to the water channel by the water pump body 2, thereby facilitating irrigation of crops.

[0038] During the water pumping process of the water pump body 2, the anti-blocking assembly can filter the weeds and other impurities in the water to prevent the weeds and other impurities from entering the water pump body 2 and causing blockage.

[0039] After the water pump body 2 finishes working, the blocking slide plate 18 is lowered to press the water in the water tank 33 into the connecting pipe 9, and then the water pump body 2 and the water inlet pipe 7 are flushed to prevent a large amount of microorganisms from remaining in the water pump body 2, and the anti-blocking assembly is also flushed to prevent weeds from existing around the anti-blocking assembly.

[0040] As a further embodiment of the present application, the top four corners of the water tank 33 are fixedly connected with rectangular limiting columns 26, the rectangular limiting columns 26 are movably abutted with the wall plates at the top four corners of the blocking slide plate 18, the servo motor 3 and the water pump body 2 are fixedly connected with bases, the two bases are fixedly connected to the top wall plate of the bottom shell 1, the bottoms of the two bases are fixedly connected with a first vibration transmission column 16 and a second vibration transmission column 17, respectively, and the first vibration transmission column 16 and the second vibration transmission column 17 are used for transmitting the vibration of the water pump body 2 and the servo motor 3, respectively.

[0041] In specific implementation, during the rising of the blocking slide plate 18, as the blocking slide plate 18 rises, the top wall plate of the blocking slide plate 18 abuts against the rectangular limiting columns 26, so that there is a space above the blocking slide plate 18 for allowing the airflow flowing to the fixed ring 4 to pass through.

[0042] During the working of the servo motor 3 and the water pump body 2, the first vibration transmission column 16 and the second vibration transmission column 17 can respectively transmit the vibration generated by the water pump body 2 and the servo motor 3 during the working to the water in the water tank 33, so that the vibration force of the water pump body 2 and the servo motor 3 is transmitted to the water, and then the vibration is transmitted to all directions by the water, and the energy is attenuated, lost, and finally absorbed during the transmission process, thereby achieving the damping effect and further enhancing the damping effect of the water pump body 2 and the servo motor 3.

[0043] In the process of the operation of the servo motor 3 and the water pump body 2, a small amount of water will be leached out due to vibration, and a small amount of water will appear above the blocking slide plate 18. In this process, because there is airflow passing above the blocking slide plate 18, the airflow will accelerate the evaporation of the water, so as to achieve the purpose of cooling. At the same time, the water vapor formed after the evaporation of the water will be blown to the servo motor 3 through the fixing ring 4, which can further improve the heat dissipation effect of the servo motor 3.

[0044] As a further embodiment of the present application, the first vibration transmission column 16 and the second vibration transmission column 17 both penetrate the top wall plate of the bottom shell 1 and extend to the bottom wall plate of the water tank 33. The bottom of the first vibration transmission column 16 and the second vibration transmission column 17 is fixedly connected with the bottom wall plate of the water tank 33. The first vibration transmission column 16 and the second vibration transmission column 17 are both slidably sleeved with the blocking slide plate 18.

[0045] In the specific implementation, in the process of the rising of the blocking slide plate 18, the blocking slide plate 18 will slide relative to the first vibration transmission column 16 and the second vibration transmission column 17.

[0046] As a further embodiment of the present application, the top of the bottom shell 1 is communicated with the first air pipe 10. The end of the first air pipe 10 away from the bottom shell 1 is communicated with the air pump 5. The end of the air pump 5 away from the first air pipe 10 is communicated with the second air pipe 11. The end of the second air pipe 11 away from the air pump 5 is communicated with a plurality of communication air pipes 21. The inside of the fixing ring 4 is provided with a ring groove 20. The end of the plurality of communication air pipes 21 away from the second air pipe 11 is communicated with the ring groove 20. The fixing ring 4 is located on the side of the servo motor 3 away from the water pump body 2. The side of the fixing ring 4 close to the servo motor 3 is provided with a plurality of air holes. The air holes are communicated with the ring groove 20. The side of the air holes away from the ring groove 20 is provided with a dustproof filter screen 22. The air pump 5 can also supply air to the space above the blocking slide plate 18 in the water tank 33 in the reverse direction. The air inlet end and the air outlet end of the air pump 5 can be converted with each other. The forward and reverse rotation of the air pump 5 can be switched to achieve this. This technology is the prior art, and will not be disclosed in detail here.

[0047] In the specific implementation, in the process of the operation of the servo motor 3, the air pump 5 is turned on. The air pump 5 is rotated in the forward direction. The air pump 5 extracts air from the space above the blocking slide plate 18 in the bottom shell 1. The airflow enters the air pump 5 through the first air pipe 10, then enters the second air pipe 11, then enters the communication air pipe 21 after leaving the second air pipe 11, then enters the ring groove 20, and finally blows on the outside of the servo motor 3 through the dustproof filter screen 22. The air around the servo motor 3 is circulated to achieve the purpose of heat dissipation of the servo motor 3.

[0048] After the irrigation work is finished, the servo motor 3 is controlled to stop working, and after the water in the water outlet pipe 6 is backflowed, the air pump 5 is controlled to reverse rotation, so that the air pump 5 extracts air from one end of the dust filter screen 22 and sucks the air into the bottom shell 1, so as to push the blocking slide plate 18 to descend. After the blocking slide plate 18 descends, the water in the water tank 33 is squeezed, so that the water in the water tank 33 can enter the water outlet pipe 6 through the communication pipe 9, and then the reverse flushing of the water pump body 2 and the water inlet pipe 7 is realized.

[0049] As a further embodiment of the application, a plurality of transverse holes are arranged on one side of the top of the bottom shell 1, and an electromagnetic one-way valve 25 is arranged in each of the transverse holes. A contact switch 23 is fixedly connected to the center of the inner top of the bottom shell 1, and the contact switch 23 is electrically connected with the electromagnetic one-way valve 25. An abutting block 24 is fixedly connected to the center of the top of the blocking slide plate 18, and the abutting block 24 is in movable abutment with the contact switch 23. When the rectangular limiting column 26 abuts against the blocking slide plate 18, the transverse hole is in communication with the first air pipe 10 above the side edge of the blocking slide plate 18. The electromagnetic one-way valve 25 can only allow external air to enter the bottom shell 1.

[0050] In the specific implementation, during the ascending of the blocking slide plate 18, the contact switch 23 abuts against the abutting block 24 as the blocking slide plate 18 ascends. After the contact switch 23 is abutted, the electromagnetic one-way valve 25 is controlled to open, so that the air pump 5 can extract air from above the blocking slide plate 18 after being opened, and external air enters the space above the blocking slide plate 18 through the electromagnetic one-way valve 25.

[0051] After the irrigation work is finished, the air pump 5 is controlled to reverse, and the air pump 5 blows air into the space above the blocking slide plate 18 in the bottom shell 1. After the airflow enters the space above the blocking slide plate 18, it cannot leave from the electromagnetic one-way valve 25, so that the air pressure in the space above the blocking slide plate 18 increases, so as to press the blocking slide plate 18 downward.

[0052] As a further embodiment of the application, an electromagnetic valve 15 is arranged at the end of the water outlet pipe 6 away from the water pump body 2. The communication pipe 9 is in communication with the water tank 33 at the end away from the water outlet pipe 6, and the communication position is located at the bottom of one side of the water tank 33. An electromagnetic three-way valve 14 is arranged at the communication position of the water outlet pipe 6 and the communication pipe 9. The inner diameter of the pipeline close to the water tank 33 at one end of the communication pipe 9 is smaller than the height of the blocking slide plate 18. An electric control valve is arranged at the communication position of the communication pipe 9 and the water tank 33. The electric control valve is in a closed state during the upward sliding of the blocking slide plate 18, and is in an open state during the downward sliding of the blocking slide plate 18.

[0053] In the specific implementation, during the operation of the servo motor 3, the electromagnetic valve 15 is in the open state, and the electromagnetic three-way valve 14 is connected between the one end of the water outlet pipe 6 close to the water pump body 2 and the one end of the electromagnetic valve 15, so that the water flow can flow out through the water outlet pipe 6.

[0054] After the irrigation work is completed, the electromagnetic valve 15 is in the closed state, and the electromagnetic three-way valve 14 is connected between the one end of the communication pipe 9 away from the water tank 33, so that the communication pipe 9 can guide the water in the water tank 33 to the water outlet pipe 6, and then flow away from the electromagnetic valve 15, thereby washing the water pump body 2 and the water inlet pipe 7.

[0055] The inner diameter of the pipe close to the one end of the communication pipe 9 is smaller than the height of the blocking slide plate 18, so that the space above and below the blocking slide plate 18 does not cross the communication pipe 9 at the position where the blocking slide plate 18 contacts the communication pipe 9.

[0056] As a further embodiment of the present application, a drain hole is formed in the center of the bottom of the bottom shell 1, a valve 13 is arranged in the drain hole, and an external water pipe 12 is connected to the bottom of the bottom shell 1, the external water pipe 12 is used to supply water to the water tank 33, and a block valve is arranged at the connection between the external water pipe 12 and the water tank 33.

[0057] In the specific implementation, after the blocking slide plate 18 is slid downward to the position where the bottom wall plate is lower than the minimum diameter of the communication pipe 9, the valve 13 is opened to drain the excess water in the water tank 33, the one end of the external water pipe 12 away from the water tank 33 is connected to a high-pressure water pump, the one end of the high-pressure water pump away from the external water pipe 12 is connected to a tap water, the tap water is used to wash the water pump body 2, and the high-pressure water pump is used to supply water to the water tank 33, after the water tank 33 is filled with water, the high-pressure water pump and the block valve are closed.

[0058] As a further embodiment of the present application, the anti-blocking assembly comprises a ring plate 8 fixedly connected to the one end of the water inlet pipe 7 away from the water pump body 2, the ring plate 8 is fixedly connected to the outer wall of the end of the water inlet pipe 7, a plurality of filter columns 34 are fixedly connected to the bottom of the ring plate 8, a blocking plate 28 is fixedly connected to the one end of the filter column 34 away from the ring plate 8, and a filter screen 31 is fixedly connected to the one end of the water inlet pipe 7 away from the water pump body 2.

[0059] In the specific implementation, during the operation of the water pump body 2, the water flow flows into the water inlet pipe 7 through the plurality of filter columns 34, and the filter columns 34 and the filter screen 31 are arranged to effectively prevent the water grass or fish in the water from being sucked into the water inlet pipe 7, avoid the water pump body 2 being blocked by the water grass or fish, and prevent the fish from being killed by the impeller in the water pump body 2, thereby protecting the ecological environment of the fish in the pond.

[0060] As a further embodiment of the present application, a rotating shaft 29 is rotatably connected at the bottom center of the blocking plate 28, the top of the rotating shaft 29 is fixedly connected with a scraping strip 30, the scraping strip 30 abuts against a filter screen 31, and a plurality of helical blades 32 are fixedly connected to the outer wall of the rotating shaft 29. A waterproof bearing is arranged at the connection between the rotating shaft 29 and the blocking plate 28, and the rotation of the rotating shaft 29 is realized by the waterproof bearing.

[0061] In specific implementation, in the process of water pumping by the water pump body 2, the flow of water will wash the helical blades 32, so that the helical blades 32 will also rotate, and in the process of rotation of the helical blades 32, the scraping strip 30 will be driven to rotate, thereby cleaning the filter screen 31, which can effectively prevent the filter screen 31 from being blocked.

[0062] As a further embodiment of the present application, a plurality of supporting rods are fixedly connected to the side of the blocking plate 28 away from the ring plate 8, the end of the supporting rod away from the blocking plate 28 is fixedly connected with a bottom plate 27, the top of the bottom plate 27 is fixedly connected with a plurality of helical rods 19, the helical rods 19 extend above the ring plate 8, and the helical rods 19 are located outside the ring plate 8, the plurality of filter columns 34 and the blocking plate 28. The specific material of the helical rod 19 is spring, which can sway in water.

[0063] In specific implementation, in the process of water pumping by the water pump body 2, the flow of water will also drive the helical rods 19 to sway, and by the swaying of the helical rods 19, fish flowing around the ring plate 8 along with the water flow can be hit in the process of water pumping by the water pump body 2, which can drive the fish away, and secondly, the helical rods 19 can also filter the waterweeds flowing to this place along with the water flow, so as to avoid the waterweeds entering the filter screen 31 and causing the filter screen 31 to be blocked.

[0064] Working principle of the present application:

[0065] In use, the present application first supplies water to the external water pipe 12 by the high-pressure water pump, and then the water flow enters the water tank 33 through the external water pipe 12 to push the blocking slide plate 18 to rise, in this process, the electric control valve at the communication between the connecting pipe 9 and the water tank 33 and the valve 13 at the bottom of the water tank 33 are both in the closed state, while the blocking valve at the communication between the external water pipe 12 and the water tank 33 is opened, and after the water supply is completed, the blocking valve is closed.

[0066] With the rising of the blocking slide plate 18, the abutting block 24 contacts the contact switch 23, thereby opening the electromagnetic one-way valve 25, and then the air pump 5 is opened to inflate the servo motor 3, and in the process of working of the air pump 5, the airflow can also clean the floating dust falling on the servo motor 3, which is conducive to avoiding the situation that the heat dissipation efficiency of the servo motor 3 itself is reduced due to the existence of floating dust on the servo motor 3.

[0067] After the blocking slide 18 rises to the point where it abuts the rectangular limit column 26, the high-pressure water pump stops supplying water, and then the servo motor 3 is turned on, so that the servo motor 3 drives the water pump body 2 to perform the irrigation work. During the irrigation work, the solenoid valve 15 is in the open state, and the solenoid three-way valve 14 connects the water outlet end of the water pump body 2 with the end of the water outlet pipe 6 away from the water pump body 2, so that the water flow extracted by the water pump body 2 can smoothly flow out through the end of the water outlet pipe 6 away from the water pump body 2.

[0068] It should be noted that the end of the outlet pipe 6 away from the pump body 2 can be connected to an external pipe to pump the pumped water into the canal. In the prior art, pumping water for agricultural irrigation is usually carried out in river tributaries, ponds, or small reservoirs near farmland. In such environments, especially ponds, ponds are often used for fish farming. This is prior art and will not be disclosed in detail here.

[0069] After the irrigation operation is completed, the air pump 5 is controlled to supply air in the reverse direction, so that the air flow enters the space above the blocking slide 18 in the bottom shell 1, causing the air pressure in the space above the blocking slide 18 to increase, thereby forcing the blocking slide 18 to slide downward. Subsequently, the blocking slide 18 squeezes the water in the water tank 33, causing the water in the water tank 33 to enter the water outlet pipe 6 through the connecting pipe 9, then flow into the water pump body 2, and finally flow out through the water inlet pipe 7 and the anti-blocking component. During the reverse rotation of the air pump 5, the electric control valve opens, the solenoid valve 15 closes, and the solenoid three-way valve 14 connects the connecting pipe 9 and the water outlet pipe 6.

[0070] As the blocking slide 18 descends, when the bottom wall plate of the blocking slide 18 moves below the connecting pipe 9, the valve 13 opens to discharge excess water in the water tank 33. As the blocking slide 18 moves, the blocking slide 18 will finally move below the connection point between the connecting pipe 9 and the water tank 33, and the gas pumped into the space above the blocking slide 18 in the bottom shell 1 by the air pump 5 will flow into the water outlet pipe 6 through the connecting pipe 9, and then flow into the water through the water pump body 2 and the water inlet pipe 7.

[0071] After the anti-blocking component is flushed with water, the gas pumped into the space above the blocking slide 18 in the bottom shell 1 by the air pump 5 is in a high-pressure state at this time. After the connecting pipe 9, the space above the blocking slide 18 in the bottom shell 1 form a passage with the air pump 5, the high-pressure gas will enter the water pump body 2 through the outlet pipe 6, and then impact the anti-blocking component through the water inlet pipe 7. The high-pressure gas is used to backwash the anti-blocking component again to avoid impurities on the anti-blocking component. At the same time, the high-pressure gas will also push the aquatic plants and fish gathered around the anti-blocking component due to the water flow to a farther distance, to prevent fish from building nests around the anti-blocking component and to prevent aquatic plants from taking root and growing around the anti-blocking component.

[0072] With the continuous reverse rotation of the air pump 5, the flow of the air flow can accelerate the evaporation of the residual water stains in the water pump body 2, the water outlet pipe 6 and the water inlet pipe 7, thereby avoiding the case that the residual water stains rust the water inlet pipe 7, the water outlet pipe 6 and the water pump body 2. In addition, the air pumped out by the air pump 5 will finally flow into the water through the anti-blocking assembly, and can also play the purpose of oxygenating the water pond, river tributary or small reservoir, so as to increase the oxygen content in the water and facilitate the fish to live in the water.

[0073] In the process of the fixed ring 4 blowing air to the servo motor 3, the flow of the air flow can also accelerate the evaporation of the water vapor, thereby reducing the water vapor outside the servo motor 3 and the water pump body 2, and being beneficial to inhibit the case that the servo motor 3 and the water pump body 2 outside are rusted due to the existence of a large amount of water vapor.

[0074] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
