[0002] In water conservancy engineering systems, control gates play an indispensable role as key facilities for regulating water flow, ensuring the rational allocation of water resources, and safeguarding flood control. With the intensification of global climate change and the increasing frequency of extreme rainfall events, the pressure on river flood control has significantly increased. At the same time, the rapid pace of urbanization has led to numerous problems for the ecological environment surrounding rivers, such as industrial wastewater discharge and domestic sewage pollution. Therefore, the need for scientific management of river water resources and ecological protection is becoming increasingly urgent.

[0003] Traditional hydraulic control gates have revealed a series of problems in practical applications. The gate raising and lowering control of some control gates is not precise enough, making it difficult to achieve refined flow regulation according to different hydrological conditions and engineering needs, resulting in low water resource utilization efficiency. Furthermore, due to complex water flow conditions and long-term operation, traditional control gates suffer from insufficient structural stability, severe component wear, high maintenance frequency, and high maintenance costs, making them unsuitable for the long-term stable operation requirements of modern hydraulic engineering projects.

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a hydraulic engineering control gate structure, including,

[0027] The support assembly 100 includes a base 101, a column 102 fixedly connected to the side wall of the base 101, a housing 103 fixedly connected to the end of the column 102, and a base plate 104 fixedly connected to the side wall of the housing 103.

[0028] The gate assembly 200 includes a gate plate 201 inserted into the middle of the housing 103, a guide post 202 fixedly connected to the upper end of the gate plate 201, a motor 203 fixedly connected to the side wall of the housing 103, and a main shaft 204 rotatably installed inside the housing 103. The gear on the side wall of the main shaft 204 meshes with the rack on the side wall of the guide post 202. The output end of the motor 203 is connected to the main shaft 204 via a reducer.

[0029] The base 101 provides stable support and a mounting platform for the entire gate body. The column 102 provides reliable support for components such as the housing 103. The side wall of the housing 103 is connected to the base plate 104, further enhancing the stability and structural strength of the entire support assembly, and also providing a reference plane for the operation of the gate assembly. The gate plate 201, as a component directly controlling water flow, is rectangular and typically made of corrosion-resistant, high-strength materials. It is precisely inserted into a groove in the middle of the housing 103, allowing it to move up and down along the groove to open and close the water flow channel. The guide column 202 meshes with the gears on the side wall of the main shaft 204, providing precise guidance and power transmission for the raising and lowering of the gate plate 201. When the motor 203 operates, it drives the main shaft 204 to rotate, and through the meshing of the gear and rack, the rotational motion is converted into the linear raising and lowering motion of the guide column 202 and the gate plate 201.

[0030] Specifically, the gate assembly 200 also includes a rubber pad 205 inserted into the side wall of the base 101, the end of the rubber pad 205 being inserted into the side wall of the column 102, the inside of the column 102 having a slot for use with the gate plate 201, and the upper end of the rubber pad 205 having a beveled structure for use with the bottom edge strip of the gate plate 201. The gate assembly 200 also includes a first spring 206 fixedly connected to the side wall of the base 101, the end of the first spring 206 being fixedly connected to the side wall of the rubber pad 205.

[0031] The inclined structure designed at the upper end of the rubber pad 205 is adapted to the bottom edge strip of the gate 201. When the gate 201 is closed, it can form a good sealing effect and effectively prevent water leakage. When the gate 201 is pressed down, the first spring 206 is compressed and generates elastic force, which further enhances the tightness of the seal. When the gate 201 is raised, the first spring 206 will release the previously stored elastic force and return the rubber pad 205 to its original position, protecting the area below the gate 201 and reducing sludge accumulation.

[0032] Furthermore, the gate assembly 200 also includes a frame 207 fixedly connected inside the housing 103, and a connecting rod 208 slidably installed on the side wall of the frame 207. The connecting rod 208 is fixedly connected to the end of the guide post 202 by bolts. The gate assembly 200 also includes a support rod 209 movably inserted into the end of the frame 207, and a pull rod 210 hinged to the end of the support rod 209. The end of the pull rod 210 is hinged to the end of the connecting rod 208. The gate assembly 200 also includes a second spring 211 sleeved on the side wall of the end of the support rod 209, and a nut 212 threadedly connected to the top of the support rod 209. The lower end of the second spring 211 is in elastic contact with the side wall of the frame 207, and the nut 212 is engaged with the upper end of the second spring 211.

[0033] The connecting rod 208 is bolted to the end of the guide column 202 and can move as the guide column 202 rises and falls. A support rod 209 is movably inserted into the end of the frame 207, with a tie rod 210 hinged to its end. The other end of the tie rod 210 is hinged to the end of the connecting rod 208, forming a movable linkage mechanism. A second spring 211 is sleeved on the side wall of the end of the support rod 209, with its lower end in elastic contact with the side wall of the frame 207 and its upper end limited by a threaded nut 212. This spring provides buffering and stabilization during the raising and lowering of the gate, and the preload of the second spring 211 can be adjusted by adjusting the nut 212 to adapt to different operating conditions.

[0034] Preferably, the support assembly 100 further includes a baffle 105 fixedly connected to the side wall of the housing 103, and a cover plate 106 fixedly connected to the middle of the housing 103. The cover plate 106 is snapped onto the outside of the motor 203, and the baffle 105 is snapped onto the outside of the frame 207.

[0035] Among them, the baffle 105 can prevent debris from entering the gate body and affecting the operation of the components; the cover plate 106 is used to tightly wrap the motor 203, which can not only prevent dust and water, but also reduce the external interference to the motor 203 during operation and ensure its stable operation.

[0036] In use, when the control gate needs to be opened, the motor 203 is started. The power of the motor 203 is reduced and amplified by the reducer and then transmitted to the main shaft 204, causing the main shaft 204 to start rotating. The gear on the side wall of the main shaft 204 meshes with the rack on the side wall of the guide column 202. As the main shaft 204 rotates, the gear drives the guide column 202 to move upward, which in turn drives the gate plate 201 to slowly rise along the channel in the middle of the housing 103. The water flow channel gradually opens, and the water can flow smoothly through the control gate.

[0037] During the upward movement of the gate 201, the connecting rod 208 moves upward along with the guide column 202, driving the support rod 209 to slide within the frame 207 via the pull rod 210. The second spring 211 acts as a buffer during this process, preventing the gate from rising too quickly and causing impact. When it is necessary to close the control gate, the motor 203 rotates in reverse, and the main shaft 204 reverses accordingly. The guide column 202 and the gate 201 gradually descend under the action of gravity and gear and rack transmission. When the gate 201 descends to contact the rubber pad 205, as the gate continues to press down, the first spring 206 is compressed, and the rubber pad 205 undergoes elastic deformation, tightly fitting the bottom edge strip of the gate 201 to achieve a good seal, preventing water flow and completing the closing operation of the control gate.

[0038] In summary, the precise coordination of the motor, reducer, and rack and pinion transmission system enables smooth and accurate raising and lowering of the gate, thereby allowing for precise control of river flow and meeting the operational needs of water conservancy projects under various conditions. The gate exhibits excellent sealing performance when closed, effectively reducing water leakage and improving water resource utilization efficiency. It also avoids water waste and environmental problems caused by leakage. The gate can buffer the impact force during raising and lowering and can absorb the force of the water flow on the gate to a certain extent, reducing component wear, extending the service life of the gate, and lowering maintenance costs. It can adapt to different river flow conditions and operating requirements, ensuring stable and reliable operation.
