Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy projects, and specifically relates to a water storage gate valve assembly for agricultural irrigation in a water conservancy project. Background Technique

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. When diverting water resources in a water conservancy project, irrigation canals are generally used. An irrigation canal is a waterway connecting an irrigation water source and irrigated land, and can transport and distribute the water volume drawn from the water source to various parts of the irrigation area. When irrigating, it is necessary to intercept and cut off the water in the canal according to actual needs, so a water storage gate valve has become an indispensable device in the irrigation canal; when it is closed, it can intercept the upstream water source for water storage, and when agricultural irrigation is needed, the gate valve can be opened to discharge the accumulated water body for agricultural irrigation use.

[0003] There are often a large number of pollutants such as weeds and leaves in agricultural irrigation canals. These sundries will enter the water inlet gap of the farmland when flowing with the water flow, resulting in the blockage of the water inlet gap, which will block the speed of water entering the farmland and affect the irrigation efficiency. Traditional gate valves can only control the flow of water when in use, and cannot salvage pollutants in the water during irrigation, which increases the risk of blockage of the water inlet gap of the farmland. Summary of the Invention

[0004] In order to make up for the deficiencies of the prior art, the present invention provides a water storage gate valve assembly for agricultural irrigation in a water conservancy project. The present invention mainly solves the problem that existing gate valves can only control the flow of water when in use, and cannot salvage pollutants in the water during irrigation, which leads to the blockage of the water inlet gap of the farmland.

[0005] The technical solution adopted by the present invention to solve its technical problems is: The present invention provides a water storage gate valve assembly for agricultural irrigation in a water conservancy project, including a gate valve frame, a gate plate, a threaded rod, an adjusting disc, a pulley, a pulling rope and a filter basket; sliding grooves are vertically arranged on both sides of the gate valve frame; the sides of the gate plate and the filter basket are slidably connected in the sliding grooves; pulleys are symmetrically arranged at the top of the gate valve frame; the upper end of the gate plate and the upper end of the filter basket are connected by a pulling rope that bypasses the pulley; one end of the threaded rod is fixedly connected to the middle of the upper end of the gate plate; the threaded rod is threadedly connected to an adjusting disc rotatably connected to the upper end of the gate valve frame.

[0006] When it is necessary to raise the filter basket, the regulating disc is rotated, and then the gate plate is driven to descend by the transmission of the threaded rod. During the descent of the gate plate, the filter basket is pulled up by the action of the pulling rope and the pulley. Then, weeds and other sundries in the agricultural irrigation canal are filtered and removed by the filter basket, thereby improving the cleanliness of the water quality and being more conducive to farmland irrigation. Moreover, the removal of weeds and other sundries can prevent the agricultural irrigation canal from being blocked, thus avoiding water overflow caused by the blockage and resulting in water resource waste, and playing a role in saving water. In this solution, the automatic alternating work of the gate plate and the filter basket is realized by connecting the gate plate and the filter basket through a pulling rope and a pulley. The structure is simple and the operation is convenient. Moreover, the gate plate and the filter basket are counterweights to each other, thereby reducing the force required for manually rotating the regulating disc and reducing the labor intensity. Moreover, when removing the weeds in the filter basket, the gate plate automatically falls to block the flow of water in the agricultural irrigation canal, thus preventing weeds from passing through the water flow at this time and further ensuring the cleaning effect of the weeds. Moreover, during the long-term water storage process, since the filter basket is raised and separated from the water flow, the filter basket is not easily rusted and corroded after being air-dried, thereby increasing the service life of the filter basket.

[0007] Preferably, driving wheels are evenly spaced vertically in the sliding groove of the gate valve frame; the driving wheels are rotatably connected to the gate valve frame through rotating shafts; both sides of the driving wheels are in contact with the gate plate and the filter basket respectively.

[0008] By arranging a row of freely rotatable driving wheels between the gate plate and the filter basket, and the cylindrical surface of the driving wheel is in contact with both of them, during the upward movement of the gate plate, the driving wheel is driven to rotate by friction. The rotation of the driving wheel will drive the filter basket to move downward, thereby preventing the filter basket from being unable to freely fall when it is unloaded, without the need for manual intervention, and improving the stability of the operation of the gate valve assembly and the convenience of use.

[0009] Preferably, the surface of the driving wheel is completely covered with wear-resistant rubber.

[0010] By completely covering the surface of the driving wheel with wear-resistant rubber, not only the friction between the driving wheel and the gate plate and the filter basket is increased, thereby improving the stability of the transmission; but also the anti-corrosion property of the wear-resistant rubber can well protect the driving wheel, thereby preventing it from being eroded by the water flow and increasing the service life of the driving wheel.

[0011] Preferably, a row of elastic bristles is arranged horizontally on the side surface of the lower end of the gate plate close to the filter basket; the ends of the elastic bristles are in contact with the filter mesh surface of the filter basket.

[0012] By horizontally arranging a row of elastic bristles on the side of the lower end of the gate plate close to the filter basket, when it is necessary to lift the filter basket, the gate plate moves downward relative to the filter basket. During the relative movement of the two, the elastic bristles on the gate plate wash the filter mesh surface on the back of the filter basket, thereby brushing off the weeds adhering to the filter mesh surface of the filter basket, facilitating the subsequent removal of weeds in the filter basket, and improving the effect of removing weeds in the agricultural irrigation canal. The elastic bristles in this solution utilize the relative movement between the gate plate and the filter basket to achieve automatic cleaning of the filter basket, and can well realize this function without adding a driving structure, thus having the characteristics of simple structure and outstanding effect.

[0013] Preferably, the elastic bristles are made of elastic metal wires.

[0014] The elastic bristles made of elastic metal wires have good toughness, so they have a good effect on brushing off the weeds adhering to the filter mesh surface of the filter basket and have a long service life.

[0015] Preferably, the filter basket includes a frame, a filter mesh surface, a salvage basket, a rotating rod, and a support rod; both sides of the frame are slidably connected in the sliding grooves on both sides of the gate valve frame; the filter mesh surface is connected to the frame; the support rods are horizontally arranged at intervals near the edge of the lower end of the frame; one end of the support rod is fixedly connected to the frame; one side of the frame is rotatably connected to the lower corner of one end of the salvage basket through the rotating rod; one end of the rotating rod is fixedly connected to the frame.

[0016] By arranging a salvage basket on one side of the filter mesh surface, the filter mesh surface filters the floating weeds in the agricultural irrigation canal and then collects them through the salvage basket arranged on one side. When the filter basket is lifted, the filtered weeds can be separated; and one end lower corner of the salvage basket is hinged to the frame through a rotating rod. After the whole filter basket is lifted, the salvage basket can be flipped around the rotating rod to pour out the weeds collected inside, making it convenient and fast to remove the weeds from the salvage basket and thus more convenient to use.

[0017] Preferably, the salvage basket includes a U-shaped frame, a bottom net plate, a connecting band, and side net plates; leakage holes are provided on the bottom surface of the U-shaped frame; one end of the bottom net plate is hinged to the lower corner of the U-shaped frame through a hinge seat embedded in the U-shaped frame; the other side of the bottom net plate is connected to the U-shaped frame through a connecting band; side net plates are fixedly connected to both sides of the U-shaped frame; a first pull ring is provided at one end of the U-shaped frame far from the hinge point.

[0018] By hinging one end of the bottom net plate at the lower corner of the U-shaped frame and connecting the other end to the U-shaped frame through a connecting belt, when the salvage basket is rotated around the rotating rod, during the process of pouring out the weeds in the salvage basket, the bottom net plate at the bottom of the salvage basket will also be turned out from the salvage basket, thus realizing the turning out of the weeds at the bottom of the salvage basket, improving the efficiency and convenience of turning out the weeds in the salvage basket. Moreover, since the connecting belt restricts the bottom net plate from completely turning out of the salvage basket, when the salvage basket is turned back to the side of the filter screen surface, the bottom net plate turns back to the bottom of the salvage basket under the action of its own gravity, thus eliminating the need for manual turning and resetting, and improving the convenience of use. The first pull ring provided on the U-shaped frame is provided to facilitate pulling one end of the salvage basket for turning.

[0019] Preferably, L-shaped guide bars are symmetrically arranged on one end face of the U-shaped frame; an extension plate is slidably connected between the two L-shaped guide bars; a second pull ring is arranged at one end of the extension plate.

[0020] By slidably connecting the extension plate on one end face of the U-shaped frame, when the salvage basket is rotated around the rotating rod, by pulling the second pull ring to draw out the extension plate from the L-shaped guide bar, the weeds poured out of the salvage basket can be conveyed outward through the extension plate, so that the weeds poured out of the salvage basket can directly enter the collection vehicle beside the agricultural irrigation canal, thus saving the workload of secondary loading of the weeds, improving the cleaning efficiency of the weeds in the agricultural irrigation canal, and reducing the cleaning difficulty at the same time.

[0021] Preferably, the inside of the gate plate is a hollow structure, and transverse reinforcing plates are evenly spaced in the hollow structure of the gate plate.

[0022] By setting the inside of the gate plate as a hollow structure, the self-weight of the gate plate can be reduced, the difficulty of rotating the adjusting disc can be reduced, and the labor intensity can be reduced; evenly spacing the transverse reinforcing plates in the hollow structure of the gate plate is to ensure its structural strength.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. When it is necessary to raise the filter basket in the present invention, by rotating the adjustment disk and then driving the gate plate to descend through the transmission of the threaded rod, during the process of the gate plate descending, the filter basket is pulled up by the action of the tension rope and the pulley. Then, weeds and other sundries in the agricultural irrigation canal are filtered and removed through the filter basket, thereby improving the cleanliness of the water quality, and further being more conducive to the irrigation of farmland. Moreover, the removal of weeds and other sundries can prevent the agricultural irrigation canal from being blocked, thereby avoiding water overflow caused by the blockage and resulting in water resource waste, and thus playing a role in saving water. In this solution, the automatic alternating work of the gate plate and the filter basket is realized by connecting the gate plate and the filter basket through a tension rope and a pulley. The structure is simple and the operation is convenient. Moreover, the gate plate and the filter basket are counterweights to each other, thereby reducing the force for manually rotating the adjustment disk and reducing the labor intensity. Moreover, when removing the weeds in the filter basket, the gate plate automatically falls to block the flow of water in the agricultural irrigation canal, thereby preventing weeds from passing through the water flow at this time and further ensuring the cleaning effect of the weeds. Moreover, during the process of long-term water storage, since the filter basket is raised and separated from the water flow, the filter basket is not easily rusted and corroded after being air-dried, thereby improving the service life of the filter basket.

[0025] 2. The present invention is provided with a row of freely rotatable transmission wheels between the gate plate and the filter basket, and the cylindrical surface of the transmission wheel abuts against both of them. Then, during the process of the gate plate moving upward, the transmission wheel is driven to rotate through friction, and the rotation of the transmission wheel will drive the filter basket to move downward, thereby preventing the filter basket from being unable to freely fall when it is unloaded, without the need for manual intervention, and thus improving the stability of the operation of the gate valve assembly and the convenience of use.

[0026] 3. The present invention is provided with a row of elastic bristles horizontally along the side surface of the lower end of the gate plate close to the filter basket. Then, when it is necessary to raise the filter basket, the gate plate moves downward relative to the filter basket. Then, during the relative movement of the two, the elastic bristles on the gate plate wash the filter mesh surface on the back of the filter basket, thereby brushing off the weeds adhered to the filter mesh surface of the filter basket, facilitating the subsequent removal of weeds in the filter basket, and thus improving the removal effect of weeds in the agricultural irrigation canal. The elastic bristles in this solution realize the automatic cleaning of the filter basket by using the relative movement between the gate plate and the filter basket, and can well realize this function without the need to increase the driving structure, and thus has the characteristics of simple structure and outstanding effect.

[0027] 4. The present invention sets a salvage basket on one side of the filter screen surface. Then, after the filter screen surface filters the floating weeds in the agricultural irrigation canal, the weeds are collected through the salvage basket set on one side. When the filter basket is lifted, the filtered weeds can be separated; one lower corner of one end of the salvage basket is hinged to the frame through a rotating rod. After the whole filter basket is lifted, the salvage basket can be flipped around the rotating rod to pour out the weeds collected inside it, making it convenient and fast to remove the weeds from the salvage basket, and thus making it more convenient to use.

Specific implementation manner

[0041] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0042] As Figures 1 to 4 Shown in the figure, a water storage gate valve assembly for agricultural irrigation water conservancy projects includes a gate valve frame 1, a gate plate 2, a threaded rod 3, an adjusting disk 4, a pulley 5, a tension rope 6 and a filter basket 7; sliding grooves are vertically arranged on both sides of the gate valve frame 1; the sides of the gate plate 2 and the filter basket 7 are slidably connected in the sliding grooves; pulleys 5 are symmetrically arranged at the top of the gate valve frame 1; the upper end of the gate plate 2 and the upper end of the filter basket 7 are connected by a tension rope 6 that bypasses the pulley 5; one end of a threaded rod 3 is fixedly connected to the middle of the upper end of the gate plate 2; the threaded rod 3 is threadedly connected to an adjusting disk 4 rotatably connected to the upper end of the gate valve frame 1.

[0043] When it is necessary to raise the filter basket 7, by rotating the adjusting disk 4, the threaded rod 3 is used to drive the gate plate 2 to descend. During the descending process of the gate plate 2, the filter basket 7 is pulled up through the action of the tension rope 6 and the pulley 5. Then, weeds and other sundries in the agricultural irrigation water channel are filtered and taken out through the filter basket 7, thereby improving the cleanliness of the water quality, and further being more beneficial to the irrigation of farmland; moreover, the removal of weeds and other sundries can prevent the agricultural irrigation water channel from being blocked, thereby avoiding water overflow caused by blockage and resulting in waste of water resources, and thus playing a role in saving water. In this solution, the automatic alternating work of the gate plate 2 and the filter basket 7 is realized by connecting the gate plate 2 and the filter basket 7 through the tension rope 6 and the pulley 5. The structure is simple and the operation is convenient. Moreover, the gate plate 2 and the filter basket 7 are counterweights to each other, thereby reducing the force for manually rotating the adjusting disk 4 and reducing the labor intensity; and when removing the weeds in the filter basket 7, the gate plate 2 automatically falls to block the flow of water in the agricultural irrigation water channel, thereby preventing weeds from passing through the water flow at this time and further ensuring the cleaning effect of the weeds; and during the long-term water storage process, since the filter basket 7 is raised out of the water flow, the filter basket 7 is not easy to rust and corrode after being air-dried, thereby improving the service life of the filter basket 7.

[0044] As Figures 4 to 5As shown, drive wheels 8 are evenly spaced vertically along the sliding groove of the gate valve frame 1; the drive wheels 8 are rotatably connected to the gate valve frame 1 through rotating shafts; both sides of the drive wheels 8 are in contact with the gate plate 2 and the filter basket 7 respectively.

[0045] By arranging a row of freely rotating drive wheels 8 between the gate plate 2 and the filter basket 7, and the cylindrical surface of the drive wheels 8 is in contact with both of them, thus when the gate plate 2 moves upward, the drive wheels 8 are driven to rotate through friction, and the rotation of the drive wheels 8 will drive the filter basket 7 to move downward, thereby preventing the filter basket 7 from being unable to fall freely when unloaded, and thus eliminating the need for manual intervention, and improving the stability of the operation of the gate valve assembly and the convenience of use.

[0046] The surface of the drive wheel 8 is entirely covered with wear-resistant rubber.

[0047] By entirely covering the surface of the drive wheel 8 with wear-resistant rubber, not only does the friction between the drive wheel 8 and the gate plate 2 and the filter basket 7 increase, thus improving the stability of transmission; but also the corrosion resistance of the wear-resistant rubber can well protect the drive wheel 8, thereby preventing it from being eroded by water flow, and improving the service life of the drive wheel 8.

[0048] As Figures 6 to 7 shown, a row of elastic brush hairs 9 are arranged horizontally along the side surface of the lower end of the gate plate 2 on the side close to the filter basket 7; the ends of the elastic brush hairs 9 are in contact with the filter mesh surface 72 of the filter basket 7.

[0049] By arranging a row of elastic brush hairs 9 horizontally along the side surface of the lower end of the gate plate 2 on the side close to the filter basket 7, thus when the filter basket 7 needs to be lifted, the gate plate 2 moves downward relative to the filter basket 7, and during the relative movement of the two, the elastic brush hairs 9 on the gate plate 2 wash the filter mesh surface 72 on the back of the filter basket 7, thus brushing off the weeds adhering to the filter mesh surface 72 of the filter basket 7, thus facilitating the subsequent removal of weeds in the filter basket 7, and improving the effect of removing weeds in the agricultural irrigation canal. The elastic brush hairs 9 in this solution utilize the relative movement between the gate plate 2 and the filter basket 7 to achieve automatic cleaning of the filter basket 7, and can well achieve this function without adding a driving structure, thus having the characteristics of simple structure and outstanding effect.

[0050] The elastic brush hairs 9 are made of elastic metal wires.

[0051] The elastic brush hairs 9 made of elastic metal wires have good toughness, thus having a good effect on brushing off the weeds adhering to the filter mesh surface 72 of the filter basket 7 and a long service life.

[0052] As Figures 8 to 9As shown in the figure, the filtering basket 7 includes a frame 71, a filter screen surface 72, a salvage basket 73, a rotating rod 74, and a support rod 75; both sides of the frame 71 are slidably connected in the sliding grooves on both sides of the gate valve frame 1; the filter screen surface 72 is connected to the frame 71; the support rods 75 are arranged at intervals in the horizontal direction near the edge at the lower end of the frame 71; one end of the support rod 75 is fixedly connected to the frame 71; one side of the frame 71 is rotatably connected to the lower corner at one end of the salvage basket 73 through the rotating rod 74; one end of the rotating rod 74 is fixedly connected to the frame 71.

[0053] By arranging the salvage basket 73 on one side of the filter screen surface 72, the filter screen surface 72 filters the floating weeds in the agricultural irrigation canal and then collects them through the salvage basket 73 arranged on one side. Thus, when the filtering basket 7 is lifted, the filtered weeds can be separated; and one lower corner at one end of the salvage basket 73 is hinged to the frame 71 through the rotating rod 74. After the whole filtering basket 7 is lifted, by flipping the salvage basket 73 around the rotating rod 74, the weeds collected inside it can be poured out, making it convenient and fast to remove the weeds from the salvage basket 73 and thus more convenient to use.

[0054] As Figure 8 , Figure 10 and Figure 11 As shown in the figure, the salvage basket 73 includes a U-shaped frame 731, a bottom net plate 732, a connecting band 733, and side net plates 734; leakage holes are arranged on the bottom surface of the U-shaped frame 731; one end of the bottom net plate 732 is hinged to the lower corner of the U-shaped frame 731 through a hinge seat embedded in the U-shaped frame 731; the other side of the bottom net plate 732 is connected to the U-shaped frame 731 through the connecting band 733; the side net plates 734 are fixedly connected to both sides of the U-shaped frame 731; a first pull ring 735 is arranged at one end of the U-shaped frame 731 away from the hinge point.

[0055] By hinging one end of the bottom net plate 732 to the lower corner of the U-shaped frame 731 and connecting its other end to the U-shaped frame 731 through the connecting band 733, when the salvage basket 73 is flipped around the rotating rod 74 and the weeds in the salvage basket 73 are poured out, the bottom net plate 732 at the bottom of the salvage basket 73 will also be flipped out of the salvage basket 73, thus realizing the dumping of the weeds at the bottom of the salvage basket 73, improving the efficiency and convenience of dumping the weeds in the salvage basket 73. And because the connecting band 733 restricts the bottom net plate 732 from completely turning out of the salvage basket 73, when the salvage basket 73 is flipped back to the side of the filter screen surface 72, the bottom net plate 732 flips back to the bottom of the salvage basket 73 under its own gravity, thus eliminating the need for manual flipping and resetting and improving the convenience of use. The first pull ring 735 arranged on the U-shaped frame is provided to facilitate pulling one end of the salvage basket 73 for flipping.

[0056] As Figure 8 , Figure 10 and Figure 11 shown, on one end face of the U-shaped frame 731, L-shaped guide bars 736 are symmetrically arranged; an extension plate 737 is slidably connected between the two L-shaped guide bars 736; a second pull ring 738 is arranged at one end of the extension plate 737.

[0057] By slidably connecting the extension plate 737 on one end face of the U-shaped frame 731, when the salvage basket 73 rotates around the rotating rod 74, by pulling the second pull ring 738, the extension plate 737 is pulled out from the L-shaped guide bar 736, so that the weeds poured out of the salvage basket 73 can be conveyed outward through the extension plate 737, so that the weeds poured out of the salvage basket 73 can directly enter the collection vehicle beside the agricultural irrigation canal, thus saving the workload of secondary loading of the weeds, improving the removal efficiency of the weeds in the agricultural irrigation canal, and at the same time reducing the difficulty of removal.

[0058] As Figure 7 shown, the inside of the gate plate 2 is a hollow structure, and transverse reinforcing plates 21 are evenly spaced in the hollow structure of the gate plate 2.

[0059] By setting the inside of the gate plate 2 as a hollow structure, the self-weight of the gate plate 2 can be reduced, the difficulty of rotating the adjustment disc 4 can be reduced, and the labor intensity can be reduced; evenly spacing and arranging the transverse reinforcing plates 21 in the hollow structure of the gate plate 2 is to ensure its structural strength.

[0060] The embodiments of the present invention have been described above in conjunction with the accompanying drawings, but the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the purpose of the present invention and the scope protected by the claims. These all belong to the protection scope of the present invention.
