Description

Technical Field

[0001] This utility model relates to the field of water conservancy and irrigation technology, and in particular to a water conservancy irrigation device for water conservancy projects. Background Technology

[0002] Water conservancy irrigation devices used in water conservancy projects mainly include water-saving irrigation equipment and irrigation and drainage equipment, such as sprinkler irrigation, micro-irrigation, all-plastic water-saving irrigation systems and pump bodies, canal seepage prevention projects, etc., which aim to make efficient use of water resources and meet the irrigation needs of farmland. Water conservancy irrigation devices used in water conservancy projects are an indispensable and important part of agricultural production. They meet the growth needs of crops and increase agricultural output by making efficient use of water resources. These devices mainly include two categories: water-saving irrigation equipment and irrigation and drainage equipment.

[0003] Traditional irrigation methods include flood irrigation and furrow irrigation. Flood irrigation is simple to operate but wastes a lot of water resources and can easily lead to soil compaction and secondary salinization. It is suitable for areas with abundant water resources and flat terrain. Furrow irrigation draws water through ditches and reduces surface contact. It is suitable for sloping land or soils with good permeability, but it still wastes water resources. Modern water-saving irrigation technologies include sprinkler irrigation, drip irrigation and micro-sprinkler belts. Innovation and efficient management of water conservancy irrigation technologies are gradually realizing the transformation from "extensive flood irrigation" to "precision water saving", providing core support for food security and sustainable development.

[0004] In existing technologies, water is usually pumped from inside the ditch during furrow irrigation. The aquatic plants or dead aquatic plants growing in the ditch, as well as garbage in the ditch, are all drawn into the pipe by the strong suction of the pump. If these impurities enter the pump, the pump is usually equipped with a metal mesh cover for filtration. However, when removing impurities, the pumping end and the metal mesh cover need to be pulled out of the water, which affects the efficiency of pumping irrigation. Summary of the Invention

[0005] The purpose of this utility model is to provide a water conservancy irrigation device for water conservancy projects, which can remove impurities from the outside of the net cover by a scraping ring after the net cover is blocked by impurities in the water, so as to avoid the impurities affecting the speed at which the water source enters the inside of the net cover, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy irrigation device for water conservancy projects, including a base and a pump body disposed on the upper side of the base, wherein conveying pipes are provided on both the left and right sides of the pump body, and a cleanup component is provided on the right side of the pump body;

[0007] The impurity removal component includes an external thread located on the right side of the outer surface of the right-side conveying pipe. An installation sleeve is threaded to the outer side of the external thread. A mesh cover is fixedly connected to the right side of the installation sleeve. A scraper ring is slidably connected to the outer side of the mesh cover. A connecting frame is slidably connected to the outer side of the right-side conveying pipe. Connecting rods are fixedly connected to the right side of the connecting frame in a circular array. Connecting ropes are fixedly connected to the front and rear sides of the left side of the connecting frame. A support base is fixedly connected to the upper side of the base. A take-up reel is rotatably connected inside the support base. A rotating rod is fixedly connected to the front side of the take-up reel. The rotating rod passes through the front side of the support base. The other end of the connecting rope is wound around the outer side of the take-up reel.

[0008] Preferably, the right side of the mounting sleeve is connected to the left side of the mesh cover, the connecting frame is cross-shaped, and the connecting rod passes through the scraper ring.

[0009] Preferably, the conveying pipe located on the right side passes through the support base, the center of the connecting frame is annular, and the shape of the inner cavity of the connecting frame is adapted to the shape of the conveying pipe.

[0010] Preferably, the base has a positioning component on both its inner and outer sides, and the positioning component includes a positioning disc fixedly connected to the right end of the connecting rod.

[0011] Preferably, the right extension rod of the positioning disk is conical, and the left sides of the outer surface of the mesh cover are arranged in a ring array and fixedly connected to the limiting rings. The connecting rod is slidably connected inside the limiting rings.

[0012] Preferably, the shape of the inner cavity of the limiting ring is adapted to the shape of the connecting rod, and the scraper ring is located between the left and right corresponding limiting rings.

[0013] Preferably, the base has a slot on the right side inside, the slot is T-shaped, and the front and rear sides of the inner wall of the horizontal part of the slot have movable slots. A baffle is slidably connected inside the movable slot. After the baffle moves, it is inserted into the horizontal plate of the slot. A pressure spring is fixedly connected between the baffle and the inside of the movable slot.

[0014] Preferably, the baffle is trapezoidal, and the shape of the baffle is adapted to the shape of the moving groove. After the connecting frame and the connecting rod are moved, they are both inserted into the slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting a scraper ring to move outside the screen and scrape away the impurities on the outside of the screen, the impurities on the outside of the screen can be removed by the scraper ring after the screen inside the water channel is blocked by impurities in the water, so as to avoid the impurities affecting the speed at which the water source enters the screen, thereby ensuring the pumping efficiency of the pump body.

[0017] 2. The connecting frame and connecting rod are locked by setting a slot, allowing them to move with the base. At the same time, the positioning plate at one end of the connecting rod can support the net in the water. Since the positioning plate is always below the net when the metal net is dropped into the water channel, it can prevent the metal net from contacting the silt at the bottom of the water, further reducing the possibility of silt clogging the net. After the water is pumped out, the net is locked to the right side of the base by the connecting frame, which facilitates the storage and transportation of the net. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 5 A water conservancy irrigation device for water conservancy projects includes a base 1 and a pump body 11 disposed on the upper side of the base 1. Both the left and right sides of the pump body 11 are provided with conveying pipes 12, and the right side of the pump body 11 is provided with a cleaning component 2.

[0029] The impurity removal component 2 includes an external thread 21 located on the right side of the outer surface of the right conveying pipe 12. An installation sleeve 22 is threaded to the outer side of the external thread 21. A mesh cover 23 is fixedly connected to the right side of the installation sleeve 22. A scraper ring 24 is slidably connected to the outer side of the mesh cover 23. A connecting frame 25 is slidably connected to the outer side of the right conveying pipe 12. A connecting rod 251 is fixedly connected to the right side of the connecting frame 25 in a circular array. A connecting rope 26 is fixedly connected to both the front and rear sides of the left side of the connecting frame 25. A support base 27 is fixedly connected to the upper side of the base 1. A take-up reel 28 is rotatably connected inside the support base 27. A rotating rod 29 is fixedly connected to the front side of the take-up reel 28. The rotating rod 29 passes through the front side of the support base 27. The other end of the connecting rope 26 is wound around the outer side of the take-up reel 28.

[0030] The right side of the mounting sleeve 22 is connected to the left side of the mesh cover 23. The connecting frame 25 is cross-shaped, and the connecting rod 251 passes through the scraper ring 24.

[0031] The right-side conveying pipe 12 passes through the support base 27, and the center of the connecting frame 25 is circular. The shape of the inner cavity of the connecting frame 25 is adapted to the shape of the conveying pipe 12.

[0032] By adopting the above technical solution, after the pump body 11 is installed above the base 1, the delivery pipes 12 are respectively installed on both sides of the pump body 11. Before dropping the end of the delivery pipe 12 with the external thread 21 into the water channel, the mesh cover 23 is installed on the outside of the external thread 21 through the mounting sleeve 22, so that the mesh cover 23 is connected to the delivery pipe 12. After the mesh cover 23 is installed, it is dropped into the water channel together with the delivery pipe 12. After the pump body 11 is started, it will draw water from the inside of the water channel. When the amount of water drawn out decreases, the rotating rod 29 can be rotated to drive the take-up reel 28 inside the support base 27 to move the connecting rope 26. As the connecting rope 26 is wound, it pulls the connecting frame 25, causing it to slide on the outside of the conveying pipe 12. After the connecting frame 25 is pulled, the connecting rod 251 fixed to the connecting frame 25 will drive the scraper ring 24 to slide on the outside of the screen 23, so that the scraper ring 24 can scrape away the impurities accumulated on the outside of the screen 23. Since the screen 23 inside the water channel is blocked by impurities in the water, the scraper ring 24 can remove the impurities on the outside of the screen 23 to avoid the impurities affecting the speed at which the water source enters the screen 23, thereby ensuring the pumping efficiency of the pump body 11.

[0033] Specifically, such as Figure 3 and Figure 4 As shown, the base 1 has a positioning component 3 on both the inner and outer sides. The positioning component 3 includes a positioning disk 32 that is fixedly connected to the right end of the connecting rod 251.

[0034] The right extension rod of the positioning disc 32 is conical, and the left sides of the outer surface of the mesh cover 23 are arranged in a ring array and fixedly connected to the limiting ring 31. The connecting rod 251 is slidably connected inside the limiting ring 31.

[0035] The shape of the inner cavity of the limiting ring 31 is adapted to the shape of the connecting rod 251, and the scraping ring 24 is located between the left and right corresponding limiting rings 31.

[0036] The base 1 has a slot 33 on the right side inside. The slot 33 is T-shaped. The front and rear sides of the inner side wall of the horizontal part of the slot 33 are provided with moving slots 34. A baffle 35 is slidably connected inside the moving slot 34. After the baffle 35 moves, it is inserted into the horizontal plate of the slot 33. A pressure spring 36 is fixedly connected between the baffle 35 and the moving slot 34.

[0037] The baffle 35 is trapezoidal, and its shape is compatible with the shape of the moving groove 34. After the connecting frame 25 and the connecting rod 251 are moved, they are both inserted into the slot 33.

[0038] By adopting the above technical solution, the connecting rod 251 will always slide inside the limiting ring 31 during the movement of the mesh cover 23, while driving the positioning plate 32 to move. After the positioning plate 32 enters the water channel, it will support the mesh cover 23. After the water pumping is completed, the connecting frame 25 together with the connecting rod 251 can be inserted into the slot 33 above the base 1. When the connecting rod 251 contacts the baffle 35 inside the slot 33, the baffle 35 will be pushed into the moving groove 34 and squeeze the pressure spring 36 inside the moving groove 34. After the connecting rod 251 has completely passed through... After the baffle 35 enters the depth of the slot 33, the pressure spring 36 pushes the baffle 35, causing the two baffles 35 to reconnect. The connecting plate and connecting frame 25 remain inside the slot 33 due to the weight of the mesh cover 23. Since the positioning plate 32 is always below the mesh cover 23 when the metal mesh cover 23 is dropped into the water channel, the metal mesh cover 23 can avoid contact with the silt at the bottom of the water, further reducing the possibility of silt clogging the mesh cover 23. After the water is pumped out, the mesh cover 23 is locked to the right side of the base 1 by the connecting frame 25, which facilitates the storage and transportation of the mesh cover 23.

[0039] Working principle: The mesh cover 23 is installed on the outside of the conveying pipe 12 through the mounting sleeve 22, and then it is dropped into the water channel along with the conveying pipe 12. When the water pumped out by the pump body 11 decreases, the rotating rod 29 can be rotated to drive the take-up wheel 28 inside the support base 27 to wind the connecting rope 26. The connecting rope 26 will pull the connecting frame 25. After the connecting frame 25 is pulled, the connecting rod 251 fixed to the connecting frame 25 will drive the scraper ring 24 to slide on the outside of the mesh cover 23, so that the scraper ring 24 scrapes the water accumulated on the mesh cover 23. The impurities on the outside are scraped off, which in turn moves the positioning plate 32. After the positioning plate 32 enters the water channel, it will support the net cover 23. After the water is pumped out, the connecting frame 25 and the connecting rod 251 can be inserted into the slot 33 above the base 1. When the connecting rod 251 contacts the baffle 35 inside the slot 33, the baffle 35 will be pushed into the moving groove 34. If the connecting rod 251 completely passes through the baffle 35, the pressure spring 36 will push the baffle 35, so that the two baffles 35 reconnect.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
