Description

Technical Field

[0001] This utility model relates to the technical field of gate opening and closing equipment, specifically a water conservancy gate opening and closing device widely used in water conservancy irrigation. Background Technology

[0002] During irrigation, a handwheel is used to rotate a threaded rod to control the opening and closing of the gate, so as to control the obstruction and connection of water flow. However, when the handwheel is not in use, dust will accumulate on its surface, making it easy to slip when rotating it.

[0003] A search revealed that patent application number 202322508284.2 discloses a novel water gate opening and closing device widely used in water conservancy irrigation, comprising a support base, a rotating frame, and an adjusting handwheel. The adjusting handwheel is movably mounted on the upper surface of the support base, and the rotating frame is movably sleeved on the surface of the support base near its upper end. An adjusting rod is movably mounted on the lower surface of one end of the rotating frame, and a brush plate is movably mounted on the front surface of the rear end of the rotating frame, above and below the adjusting handwheel.

[0004] Although this new type of water gate opening and closing device, widely used in water conservancy irrigation, uses a rotating frame, the rotating frame uses a brush plate to conveniently brush the upper and lower surfaces of the adjusting handwheel, allowing the adjusting handwheel to be used directly, the brush plate of this new type of water gate opening and closing device can only brush the upper and lower surfaces of the handwheel, and cannot brush the inner and outer curved surfaces of the handwheel, resulting in poor cleaning effect.

[0005] Therefore, we propose a hydraulic gate opening and closing device that can be widely used in water conservancy and irrigation. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a water gate opening and closing device that can be widely used in water conservancy irrigation. It solves the problem that the brush plate of the existing device can only brush the upper and lower surfaces of the handwheel, but cannot brush the inner and outer curved surfaces of the handwheel, resulting in poor cleaning effect.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a water conservancy gate opening and closing device widely used in water conservancy irrigation, including a support base, wherein a handwheel that drives the threaded rod to rotate is rotatably installed in the middle of the top surface of the support base;

[0008] The handwheel includes a rim, a connecting plate, and a center disc. The rim and the center disc are connected by the connecting plate, which has a rhomboid cross-section. A cleaning head is provided on the rim, and a drive assembly for driving the cleaning head to rotate along the outer surface of the rim is provided on the support base.

[0009] The cleaning head includes a U-shaped plate, a sliding groove, a clearance groove, a movable plate, a limiting plate, a spring, bristles, and an inclined surface. The upper and lower ends of the U-shaped plate are located on the upper and lower sides of the wheel rim, respectively. The upper and lower ends of the U-shaped plate have symmetrically distributed sliding grooves on the side of the wheel rim closer to the inner ring of the wheel rim. The movable plate is slidably fitted inside the sliding groove. The limiting plate is fixedly installed on the side of the movable plate away from the U-shaped plate. One end of the spring is fixedly welded to the four corners of the limiting plate near the U-shaped plate. The other end of the spring is respectively welded to the surface of the upper and lower ends of the U-shaped plate. The side of the U-shaped plate and the movable plate facing the wheel rim are both fixedly installed with evenly distributed bristles. The adjacent surfaces of the movable plates at the upper and lower ends of the U-shaped plate are in contact with each other in their natural state.

[0010] Preferably, both the upper and lower ends of the U-shaped plate are provided with clearance grooves that communicate with the slide groove. The bristles on the side wall of the movable plate can move in the clearance groove. By setting the clearance groove, the movable plate on the side wall of the spring can pass through, thereby allowing the spring to move up and down inside the slide groove.

[0011] Preferably, the movable plate has symmetrical inclined surfaces on both the front and rear sides facing one end of the wheel rim, and the inclination angle of the inclined surfaces is 30°. With the setting of the inclined surfaces and the connecting plate, when the cleaning head rotates along the wheel rim, the left and right sides of the connecting plate will contact the inclined surfaces, thereby moving the spring away from the wheel rim. At this time, the spring is stretched. When the cleaning head passes the connecting plate, the movable plate will return to its original position under the action of the spring force.

[0012] Preferably, the drive assembly includes a motor, a gear disk, a ring gear, and a connecting rod. The connecting rod is rotatably mounted on the outer surface of the top of the support base via a bearing ring. The motor is fixedly mounted on the support base, and the output end of the motor is fixedly mounted with a gear disk that meshes with the ring gear. The motor can drive the gear disk to rotate, thereby driving the ring gear to rotate as well.

[0013] Preferably, one end of a connecting rod is fixedly mounted on the top surface of the ring gear, and the other end of the connecting rod is fixedly mounted on the side wall of the U-shaped plate. When the ring gear rotates, it can drive the connecting rod to rotate together, and then the connecting rod drives the cleaning head to rotate along the outer surface of the wheel rim.

[0014] This utility model provides a hydraulic gate opening and closing device widely used in water conservancy and irrigation. It has the following beneficial effects:

[0015] This widely used water gate opening and closing device for irrigation uses a drive assembly to rotate a cleaning head along the outer surface of a wheel rim. During this process, bristles on the inner wall of the U-shaped plate clean the upper and lower surfaces and the outer arc surface of the wheel rim, while bristles on the side wall of the movable plate clean the inner arc surface of the wheel rim. When the cleaning head passes the connecting plate, the rhomboid and inclined cross-section of the connecting plate causes the inclined surface to contact the upper and lower sides of the connecting plate. Subsequently, the movable plates on the upper and lower sides are pushed to their sides by the connecting plate, at which point the spring is compressed to facilitate the smooth passage of the movable plates through the connecting plate. After the movable plates pass the connecting plate, the upper and lower movable plates will contact each other again under the action of the spring force, thus cleaning the inner arc surface of the wheel rim. This achieves the purpose of thoroughly cleaning the outer surface of the wheel rim, improving the cleaning effect of the wheel rim and solving the problem that the brushes of existing devices can only brush the upper and lower surfaces of the wheel, but cannot brush the inner and outer arc surfaces of the wheel, resulting in poor cleaning effect.

Detailed Implementation

[0021] 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.

[0022] Example 1:

[0023] like Figures 1-4As shown: The system includes a support base 1. A handwheel 4, which drives a threaded rod to rotate, is rotatably mounted on the center of the top surface of the support base 1. The handwheel 4 includes a rim 41, a connecting plate 42, and a central disc 43. The rim 41 and the central disc 43 are connected by the connecting plate 42, which has a rhomboid cross-section. A cleaning head 3 is mounted on the rim 41. A drive assembly 2, which drives the cleaning head 3 to rotate along the outer surface of the rim 41, is mounted on the support base 1. The cleaning head 3 includes a U-shaped plate 31, a sliding groove 32, a clearance groove 33, a movable plate 34, a limiting plate 35, a spring 36, bristles 37, and an inclined surface 38. The upper and lower ends of the U-shaped plate 31 are respectively located on the rim 41. On the upper and lower sides of the rim 41, symmetrically distributed grooves 32 are provided on the upper and lower ends of the U-shaped plate 31 near the inner ring of the rim 41. Movable plates 34 are slidably fitted inside the grooves 32. Limiting plates 35 are fixedly installed on the side of the movable plate 34 away from the U-shaped plate 31. One end of a spring 36 is fixedly welded to the four corners of the limiting plate 35 near the U-shaped plate 31. The other ends of the springs 36 are respectively welded to the surfaces of the upper and lower ends of the U-shaped plate 31. Evenly distributed bristles 37 are fixedly installed on the side of the U-shaped plate 31 and the movable plate 34 facing the rim 41. The movable plates 34 at the upper and lower ends of the U-shaped plate 31 are adjacent in their natural state. The surfaces are in contact with each other. Both the upper and lower ends of the U-shaped plate 31 are provided with clearance grooves 33 that communicate with the sliding groove 32. The bristles 37 on the side wall of the movable plate 34 can move within the clearance grooves 33. The movable plate 34 has symmetrically provided inclined surfaces 38 on its front and rear sides facing the wheel rim 41, with an inclination angle of 30°. The cleaning head 3 is driven by the drive assembly 2 to rotate along the outer surface of the wheel rim 41. During this process, the bristles 37 on the inner wall of the U-shaped plate 31 clean the upper and lower surfaces and the outer arc surface of the wheel rim 41, while the bristles 37 on the side wall of the movable plate 34 clean the inner arc surface of the wheel rim 41. When the cleaning head 3 passes through the connecting plate 42, the rhomboid cross-section and inclined surface 38 of the connecting plate 42 cause the inclined surface 38 to contact the upper and lower sides of the connecting plate 42. Subsequently, the movable plates 34 on the upper and lower sides are pushed to their sides by the connecting plate 42. At this time, the spring 36 is compressed so that the movable plates 34 can pass through the connecting plate 42 smoothly. After the movable plates 34 pass through the connecting plate 42, under the action of the spring force of the spring 36, the upper and lower movable plates 34 will contact each other again, and then clean the arc surface of the inner side of the wheel rim 41, achieving the purpose of thoroughly cleaning the outer surface of the wheel rim 41 and improving the cleaning effect of the wheel rim 41.

[0024] Example 2:

[0025] like Figures 1-2As shown: The drive assembly 2 includes a motor 21, a gear disk 22, a ring gear 23, and a connecting rod 24. The connecting rod 24 is rotatably mounted on the outer surface of the top of the support base 1 via a bearing ring. The motor 21 is fixedly mounted on the support base 1. The output end of the motor 21 is fixedly mounted with a gear disk 22 that meshes with the ring gear 23. One end of the connecting rod 24 is fixedly mounted on the top surface of the ring gear 23. The other end of the connecting rod 24 is fixedly mounted on the side wall of the U-shaped plate 31. The motor 21 can drive the gear disk 22 to rotate, which in turn drives the ring gear 23 to rotate together. When the ring gear 23 rotates, it can drive the connecting rod 24 to rotate together. Then, the connecting rod 24 drives the cleaning head 3 to rotate along the outer surface of the wheel rim 41.

[0026] The working principle and usage process of this utility model: This water conservancy gate opening and closing device, widely used in water conservancy irrigation, is used by first starting the motor 21 to drive the gear disk 22 to rotate. Through the meshing of the gear disk 22 and the ring gear 23, the ring gear 23 and its top connecting rod 24 can be driven to rotate together. Then, the connecting rod 24 drives the cleaning head 3 to rotate along the outer surface of the wheel rim 41. During this process, the brush bristles 37 on the inner wall of the U-shaped plate 31 clean the upper and lower surfaces and the outer arc surface of the wheel rim 41, and the brush bristles 37 on the side wall of the movable plate 34 clean the wheel rim 41. The inner arc surface of the wheel rim 41 is cleaned. When the cleaning head 3 passes the connecting plate 42, the diamond-shaped cross section and inclined surface 38 of the connecting plate 42 cause the inclined surface 38 to contact the upper and lower sides of the connecting plate 42. Then, the upper and lower movable plates 34 are pushed to their sides by the connecting plate 42. At this time, the spring 36 is compressed so that the movable plate 34 can pass smoothly through the connecting plate 42. After the movable plate 34 passes the connecting plate 42, the upper and lower movable plates 34 will contact each other again under the action of the spring force of the spring 36, and then the inner arc surface of the wheel rim 41 will be cleaned.
