Description

Technical Field

[0001] The utility model relates to a field water inlet gate for automatic irrigation. Background Art

[0002] In the irrigation of farmland, canals built in the fields are generally used to transport irrigation water. The canals should be higher than the rice fields, and diversion equipment is installed on the canals. The diversion equipment is controlled by valves. When irrigation is needed, the corresponding valves are opened manually to divert the water in the canals to the area that needs irrigation.

[0003] Most of the valves on the canal are opened and closed manually. Because the area of ​​the rice field is large and some rice fields are not concentrated in the area, the opening and closing of the valve requires more labor costs. However, if the valve is set to mechanical control, the cost is increased. In order to avoid this situation, valves that can be opened automatically are set in some field irrigation. In the authorized Chinese invention patent [Announcement No. CN110438954B, Patent Name: A Field Automatic Control Water Inlet Gate], the lever principle is used as the basis to control the valve through the liquid level of the rice field. However, the buoyancy of the float changes the counterweight on both sides of the lever to achieve the rise or fall of the valve plate on the valve. However, most traditional valve plates are made of metal, which is heavy and requires a large pulling force when rising. Therefore, the valve plate on the valve used in general field irrigation is raised by the rotation of the threaded rod. The weight ratio on both sides of the lever is changed by the buoyancy of the float to achieve the rise and fall of the valve plate. The uncertainty is large and the reliability is low. If the weight on the valve plate is reduced, the valve will be unstable and may float up by itself under the impact of the canal water flow.

[0004] Therefore, in order to solve the above problems, an automatic irrigation field water inlet gate is provided. Utility Model Content

[0038] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0039] like Figure 1 and Figure 2 As shown, the automatic irrigation field water inlet gate comprises a water channel 1 and a water guide shell 2 connected to one side of the water channel 1, wherein the water guide shell 2 is in communication with the water channel 1;

[0040] A U-shaped water pipe 3 for siphoning water, one end of which is placed in the water guide shell 2, and the other end of which is placed in the rice field to be irrigated;

[0041] A liftable water inlet assembly is connected to the end of the U-shaped water delivery pipe 3 located inside the water guide shell 2, and the water inlet assembly is connected to a driving assembly that drives the water inlet assembly to rise and fall;

[0042] The trigger component 9 is connected to the driving component through the transmission component 8. The trigger component 9 determines whether to drive the water inlet component to descend through the transmission component 8 for water delivery and irrigation according to the water level of the rice field.

[0043] This technical solution is applicable to the situation where there is a large height difference between the canal 1 and the rice field.

[0044] The U-shaped water pipe 3 utilizes the height difference between the canal 1 and the rice field to form a siphon effect, so that the water in the canal 1 is transported to the rice field. The liftable water inlet component is used as the valve plate in the valve, which reduces the weight of the valve plate and facilitates the opening and closing of the valve. At the same time, there is no need to consider the sealing shape of the traditional valve during use, thereby reducing the construction cost.

[0045] The water inlet assembly rises and falls under the drive of the trigger assembly 9 and the transmission assembly 8. When the water level in the rice field drops, the trigger part is activated, and the trigger part drives the water inlet assembly to drop through the transmission assembly 8. The water inlet 51 of the water inlet assembly extends below the liquid level of the canal 1 to complete the siphon structure, and the water is transported to the rice field through the U-shaped water pipe 3.

[0046] The bottom side wall of the water guide shell 2 is recessed downward to form a water inlet groove, and the water inlet groove is located directly below the water inlet pipe 5 to facilitate the water in the water guide shell 2 to enter the water inlet assembly.

[0047] Embodiment 1

[0048] As one of the embodiments of this technical solution, Figure 2 As shown in or 3, the water inlet assembly includes a telescopic tube 4, the top end of the telescopic tube 4 is connected to the U-shaped water pipe 3, the bottom end of the telescopic tube 4 is connected to the water inlet pipe 5, the bottom end of the water inlet pipe 5 is provided with a water inlet 51, the surface of the water inlet pipe 5 is fixed with a fixing frame 6, the top end of the fixing frame 6 is fixedly connected to a transmission rod 7 arranged in a horizontal direction, and the transmission rod 7 is connected to the trigger assembly 9 through a transmission assembly 8.

[0049] The surface of the water inlet 51 is covered with a protective cover 53 . The surface of the protective cover 53 is provided with a plurality of evenly distributed through holes. The protective cover 53 is connected to the water inlet pipe 5 via a connecting frame 52 .

[0050] Specifically, a plurality of annular pre-folding grooves are provided on the surface of the telescopic tube 4. When the telescopic tube 4 is extended or retracted, the pre-folding grooves shrink or stretch.

[0051] In this embodiment, when the transmission rod 7 descends driven by the transmission assembly 8, the fixed frame 6 at the bottom of the transmission rod 7 drives the water inlet pipe 5 to descend. At this time, the telescopic tube 4 is extended, and the water inlet 51 on the end of the water inlet pipe 5 extends below the water surface in the guide shell during the descent process. At this time, the construction of the siphon structure is completed. Due to the height difference between the canal 1 and the rice field, the water in the canal 1 is sucked into the water inlet pipe 5 at this time, and then transported to the rice field by the U-shaped water pipe 3.

[0052] Embodiment 2

[0053] This embodiment is derived on the basis of the first embodiment. Figure 3 and 5 As shown, the transmission assembly 8 includes an outer cover shell 81, and a rotatable transmission gear 82 is arranged in the inner cavity of the outer cover shell 81, and a driving rack 83 and a driven rack 84 are respectively arranged on both sides of the transmission gear 82, and the driving rack 83 and the driven rack 84 are both meshed and connected with the transmission gear 82, and the driving rack 83 and the driven rack 84 are both slidably connected with the inner wall of the outer cover shell 81, the driven rack 84 is connected to the transmission rod 7, and the driving rack 83 is connected to the trigger assembly 9.

[0054] Specifically, the outer cover shell 81 is fixed to the support rod 97 or the ground through a rod.

[0055] In this embodiment, when the trigger assembly 9 is started, the driving rack 83 located inside the outer cover shell 81 rises, and the driving rack 83 drives the transmission gear 82 to rotate during the rising process. The transmission gear 82 drives the driven rack 84 to descend during the rotation process, and the transmission rack drives the transmission rod 7 to descend, thereby driving the water inlet assembly to descend, thereby realizing the transportation of irrigation water.

[0056] Embodiment 3

[0057] This embodiment is derived on the basis of the first and second embodiments. Figure 2 and 3 As shown, the trigger assembly 9 includes a horizontal rod 96, on which a fixed portion is provided. Both ends of the horizontal rod 96 are respectively connected to a counterweight block 99 and a trigger portion, and the trigger portion detects the water level of the rice field. The bottom end of the fixed portion is rotatably connected to a support rod 97, and the support rod 97 is fixed on the ground. A connecting telescopic rod 96a is connected to the end of the horizontal rod 96 on the same side as the counterweight block 99, and the connecting telescopic rod 96a is rotatably connected to the driving rack 83.

[0058] The counterweight block 99 is connected to the horizontal rod 96 via a connecting member 98, which is a rope.

[0059] The fixing part includes a fixing sleeve 95, which is slidably sleeved on the surface of a horizontal rod 96. A fixing screw 95a is threadedly connected to the fixing sleeve 95. The fixing screw 95a passes through the side wall of the fixing sleeve 95 and abuts against the surface of the horizontal rod 96. By sliding the fixing sleeve 95 on the surface of the horizontal rod 96, the position of the fulcrum of the balance structure can be adjusted to facilitate installation.

[0060] Furthermore, the trigger part includes a connecting rod 91, which is rotatably connected to the end of a horizontal rod 96. The connecting rod 91 is connected to a floating platform 93 through a connecting shaft 92. The floating platform 93 is placed inside a protective cover 94. The protective cover 94 is inserted in a rice field. A plurality of evenly distributed through holes are provided on the surface of the protective cover 94. The connecting rod 91 and the connecting shaft 92 are rotatably connected. The protective cover 94 can prevent impurities in the rice field from affecting the floating or descending of the floating platform 93. The protective cover 94 is vertically inserted into the rice field.

[0061] In this embodiment, the counterweight block 99, the trigger part and the horizontal rod 96 constitute a balance structure. When the liquid level in the rice field is normal, the floating platform 93 floats on the liquid surface. Under the balancing of the counterweight block 99, the horizontal rod 96 is distributed in the horizontal direction. When the water level in the rice field drops, the floating platform 93 drops along with the liquid level in the rice field. The descent of the floating platform 93 drives one side of the horizontal rod 96 connected to it to move downward. At this time, the horizontal rod 96 rotates along the center of the circle at the rotating connection between the fixed sleeve 95 and the support rod 97, and one end of the horizontal rod 96 connected to the telescopic rod 96a rises, thereby driving the driving rack 83 connected to the telescopic rod 96a to move upward, so that the driven rack 84 drives the water inlet assembly to move downward, completing the construction of the siphon structure.

[0062] Embodiment 4

[0063] This embodiment is derived on the basis of the first embodiment, the second embodiment and the third embodiment. Figure 1 As shown, it also includes a guide part, which is arranged at the connection point between the water channel 1 and the water guide shell 2. The guide part is composed of a guide telescopic rod 12 and a guide plate 11. The guide plate 11 is rotatably connected to the inner wall of the water channel 1. One end of the guide telescopic rod 12 is rotatably connected to the guide plate 11, and the other end of the guide telescopic rod 12 is rotatably connected to the side wall of the water channel 1. An elastic member is connected to the surface of the guide telescopic rod 12.

[0064] The guide telescopic rod 12 is composed of two tubes with different diameters that are sleeved together, and the two ends of the elastic member are respectively fixed on the two tubes, and the guide plate 11 is tilted in the opposite direction of the water flow.

[0065] In this embodiment, when the water in the canal 1 flows, a part of the water is guided into the water guide shell 2 through the guide plate 11. When the water flow is large, the water pressure on the guide plate 11 is large, and the guide plate 11 rotates toward the side of the water flow. The elastic member is in a stretched and expanded state. At this time, the water interception area of ​​the guide plate 11 in the canal 1 increases, and more water is intercepted into the water guide shell 2. When the water flow becomes smaller, the pressure on the guide plate 11 becomes smaller. At this time, the elastic member begins to recover its deformation and shrink, driving the water guide plate to rotate toward one side of the water guide shell 2. At this time, the water interception area of ​​the guide plate 11 in the canal 1 is reduced, and the amount of water intercepted is reduced.

[0066] The diversion part can adjust the water interception amount according to the size of the water flow, and cooperate with the water inlet component that can be raised and lowered to balance the water volume of each diversion channel of the water channel 1.

[0067] By adjusting the length of the telescopic rod, the rotation angle range of the guide plate 11 is adjusted, and the inclination angle of the guide plate 11 at the upstream of the water channel 1 is smaller than the inclination angle of the guide plate 11 at the downstream of the water channel 1 .

[0068] The elastic member is an elastic spring or spring sheet or other components that can play the same or similar role.

[0069] The utility model is not limited to the above-mentioned embodiments. Any changes in shape or structure are within the protection scope of the utility model. The protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the utility model, but these changes and modifications are within the protection scope of the utility model.
