Description

Technical Field

[0001] The utility model relates to the technical field of gates, in particular to a water diversion gate for water resources scheduling in irrigation areas. Background Technique

[0002] An irrigation area refers to an irrigation area with reliable water sources and diversion, transportation, and distribution channel systems and corresponding drainage channels. It is the product of human economic activities and develops with the development of social economy. Among them, the water diversion gate is a commonly used device for water resources scheduling in irrigation areas. The water diversion gate is often set at the intersection of the main channel and the branch channel to control the diversion of water resources. Opening the water diversion gate can enable the diverted water resources to flow into the farmland along the small water conservancy channels in the fields, thereby achieving the purpose of irrigation.

[0003] The water diversion gate mainly includes a gate frame, a gate, and a lifting mechanism. The lifting mechanism is used to lift and lower the gate. The gate frame is buried at the intersection of the main channel and the branch channel. The inner wall of the gate frame is provided with a chute for connecting the gate. In order to ensure the sealing performance of the water diversion gate, some gates usually also have a groove communicated with the chute on the inner wall of the gate frame at the bottom of the gate frame. When the gate falls, the bottom can fall into the groove at the bottom, thereby realizing the sealing of the bottom of the gate. However, setting a groove at the bottom of the gate frame has the following defects while solving problems:

[0004] Since the water in the channel usually contains sediment, when the water passes through the gate, the sediment will accumulate in the groove at the bottom of the gate frame. When the gate descends, the sediment will prevent the gate from entering the groove below the gate frame, resulting in a poor sealing effect. Content of the Utility Model

[0005] The purpose of the utility model aims to solve at least one of the technical defects described in the background technique.

[0006] Therefore, an object of the utility model is to provide a water diversion gate for water resources scheduling in irrigation areas, aiming to solve the problem that sediment is easily deposited in the groove at the bottom of the gate frame of the existing water diversion gate, resulting in a poor sealing effect.

[0007] To achieve the above object, an embodiment of one aspect of the utility model provides a water diversion gate for water resources scheduling in irrigation areas, including a gate frame and a gate. Chutes are opened on both sides of the inner wall of the gate frame. A groove is opened at the bottom inside the gate frame. A lifting platform is slidably connected inside the groove. Two sides of the top of the lifting platform are fixedly connected with pulling plates. The pulling plates and the gate are slidably connected in the chutes. A plurality of positioning holes are opened on the side surfaces of the pulling plates. Two sides of the top of the gate are fixedly connected with positioning frames. Plug rods are slidably connected inside the positioning frames.

[0008] Preferably, according to any of the above solutions, limiting grooves are provided on both sides of the inner wall of the groove, and limiting plates are fixedly connected to both sides of the lifting table.

[0009] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0010] 1. Push the two insertion rods to insert them into the corresponding positioning holes on the pull plate, and then raise the gate by a certain distance. The pull plate drives the lifting table to rise a certain distance, and then stop raising the gate. At this time, the lifting table can block the groove, so that sediment will not accumulate in the groove. When lowering the gate, lower the lifting table, and the gate can be lowered into the groove without being affected by sediment, thus ensuring the sealing effect.

[0011] 2. After the lifting table rises to a certain height, the top of the limiting plate abuts against the top of the limiting groove, and the lifting table cannot continue to rise, which plays a role in limiting the rising height of the lifting table, thus avoiding the problem that the lifting table rises too high, resulting in sediment accumulation on one side of the lifting table, and when the lifting table is lowered, the sediment enters the groove again, thereby improving the reliability.

[0012] The additional aspects and advantages of the present utility model will be partially given in the following description, partially will become obvious from the following description, or will be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present utility model provides a water diversion gate for water resource scheduling in an irrigation area.

[0022] Embodiment 1:

[0023] As Figures 1-4 shown, it includes a gate frame 1 and a gate 2. Sliding grooves 11 are provided on both sides of the inner wall of the gate frame 1, and a groove 12 is provided at the bottom inside the gate frame 1. A lifting platform 3 is slidably connected inside the groove 12, and the lifting platform 3 can slide up and down in the groove 12. Pulling plates 31 are fixedly connected to both sides of the top of the lifting platform 3. The pulling plates 31 and the gate 2 are slidably connected in the sliding grooves 11, and the pulling plates 31 and the gate 2 can slide up and down in the sliding grooves 11. A plurality of positioning holes 32 are provided on the side surfaces of the pulling plates 31. Positioning frames 21 are fixedly connected to both sides of the top of the gate 2. A plug rod 22 is slidably connected inside the positioning frames 21. Slide the plug rod 22 to insert it into the positioning holes 32. At this time, when the gate 2 is lifted upward again, the pulling plates 31 can be driven to slide upward, and thus the lifting platform 3 at the bottom of the pulling plates 31 can be driven to rise.

[0024] As Figure 3 shown, a limiting block 23 is fixedly connected to one side of the plug rod 22, and a dial rod 24 is fixedly connected to one side of the end of the plug rod 22. The limiting block 23 and the dial rod 24 can limit the plug rod 22 so that it cannot slide out of the positioning frame 21, and the setting of the dial rod 24 facilitates pushing and pulling the plug rod 22 to slide.

[0025] As Figures 1-2As shown in the figure, a through hole 14 is opened at the top of the gate frame 1. A screw rod 25 is fixedly connected to the top of the gate 2. The screw rod 25 passes through the through hole 14 to the upper side of the gate frame 1. A housing 4 is fixedly connected to the top of the gate frame 1. Through holes corresponding to the through hole 14 are opened at the top and bottom of the housing 4. A worm gear 41 is rotatably connected inside the housing 4. A threaded hole 42 is opened in the middle of the worm gear 41. The threaded hole 42 corresponds to the through hole 14. The screw rod 25 passes through the housing 4, and the screw rod 25 is threadedly connected inside the threaded hole 42. By rotating the worm gear 41 to rotate on the outer surface of the screw rod 25, the screw rod 25 can be lifted and lowered, so as to achieve the purpose of lifting and lowering the gate 2. A worm 43 is rotatably connected to one side inside the housing 4. The worm 43 meshes with the worm gear 41. Rotating the worm 43 can drive the worm gear 41 to rotate, and this structure has a self-locking function, which can lock the height of the gate 2. One end of the worm gear 41 is fixedly connected with a connecting head 44 for connecting a wrench. By connecting the wrench with the connecting head 44, the worm 43 can be rotated to drive the worm gear 41 to rotate.

[0026] Embodiment 2:

[0027] As Figure 2 and Figure 4 shown in the figure, on the basis of Embodiment 1, limiting grooves 13 are opened on both sides of the inner wall of the groove 12. Limiting plates 33 are fixedly connected to both sides of the lifting platform 3. The limiting plates 33 can slide up and down in the limiting grooves 13. When the limiting plates 33 rise to a certain height, the top of the limiting plates 33 abuts against the top of the limiting grooves 13, and the lifting platform 3 can no longer rise, playing a role in restricting the rising height of the lifting platform 3. And at this time, the top surface of the lifting platform 3 is flush with the top surface of the groove 12.

[0028] The working principle of the present utility model is as follows: When in use, connect the wrench with the connecting head 44, and then rotate the worm 43 to drive the worm gear 41 to rotate, thereby driving the gate 2 to rise. The water in the main channel flows into the branch channel through the lower part of the gate 2. When the gate 2 rises a certain distance so that the water flow in the branch channel reaches an appropriate flow rate, push the two insertion rods 22 to insert them into the corresponding positioning holes 32 on the pull plate 31, and then raise the gate 2 by a certain distance, so that the pull plate 31 drives the lifting platform 3 to rise. When the limiting plate 33 abuts against the top of the limiting groove 13 and the gate 2 can no longer be raised, stop rotating the worm 43.

[0029] Compared with the prior art, the present utility model has the following beneficial effects compared with the prior art:

[0030] 1. When opening the gate, when the gate 2 rises a certain distance so that the water flow in the branch channel reaches an appropriate flow rate, two inserting rods 22 are pushed to insert into the corresponding positioning holes 32 on the pull plate 31. Then the gate 2 rises a certain distance further, causing the pull plate 31 to drive the lifting platform 3 to rise a certain distance. Then stop raising the gate 2. At this time, the lifting platform 3 can block the groove 12, so that sediment will not accumulate in the groove 12. When lowering the gate 2, the lifting platform 3 is lowered, and the gate 2 can be lowered into the groove 12 without being affected by sediment, thus ensuring the sealing effect.

[0031] 2. By setting the limit groove 13 and the limit plate 33, after the lifting platform 3 rises to a certain height, the top of the limit plate 33 abuts against the top of the limit groove 13, and the lifting platform 3 cannot continue to rise, which plays a role in restricting the rising height of the lifting platform 3. And at this time, the top surface of the lifting platform 3 is flush with the top surface of the groove 12, thus avoiding the problem that the lifting platform 3 rises too high, resulting in sediment accumulating on one side of the lifting platform 3, and when the lifting platform 3 is lowered, the sediment enters the groove 12 again, thereby improving the reliability.
