Description

Technical Field

[0001] This utility model relates to the field of hydraulic gate technology, specifically to a gate with a filtering function for hydraulic engineering. Background Technology

[0002] In the field of water conservancy engineering, traditional sluice gates, as core facilities for water flow control, are mainly used for interception, flood discharge, or water level regulation, but their function is mostly limited to simple water flow obstruction. With the increasing demands for refined river ecological management and irrigation systems, water conservancy facilities often face the problem of suspended solids, aquatic plants, and garbage clogging the flow channels. In existing technologies, some improved sluice gates achieve impurity interception by adding fixed grilles or pre-filters, but under high flow velocities or conditions with abundant debris, filter pores are prone to clogging, leading to increased hydraulic losses and even structural deformation due to local pressure surges. Furthermore, manual dredging and maintenance require frequent opening and closing of the gates, severely impacting the efficiency of project operation. Therefore, there is an urgent need for an intelligent sluice gate structure with self-cleaning capabilities, dynamic filtration, and low resistance characteristics, which can ensure the accuracy of water flow control while reducing operation and maintenance costs and adapting to complex hydrological environments.

[0003] Utility model patent application number CN202421093409.8 and publication number CN222525311 U (hereinafter referred to as "Prior Art 1") discloses a gate structure for water conservancy projects. It includes a mounting frame, within which a gate is mounted. A first lead screw is threaded onto the mounting frame, with its bottom end rotatably connected to the top of the gate. The gate has multiple first rectangular through holes arranged in a rectangular array. A rectangular mounting hole is also provided on the gate, communicating with all the first rectangular through holes. A partition is slidably mounted within the rectangular mounting hole, and multiple second rectangular through holes are passed through the partition, communicating with their corresponding first rectangular through holes.

In use, the simple water passage structure facilitates slow water release, thereby effectively reducing soil erosion on the canal banks. However, in practical applications, it cannot filter out debris in the water, resulting in the gate being covered with garbage, which affects the use of the gate. Summary of the Invention

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0027] Please see Figures 1-4 As shown in the figure, this embodiment discloses a gate with a filtration function for water conservancy projects, including a support base 101, a gate device, and a filtering device; the support base 101 is used to be installed on a dam 102; the gate device is used to be installed on the support base 101 and to intercept water inside the dam 102; the filtering device is installed on both sides of the gate structure and is used to filter debris inside the dam 102.

[0028] The filtration device includes a mounting frame 103, a filter screen 104, and a lifting structure. The mounting frame 103 is located on the front and rear sides of the gate device and is fixedly connected to the inner wall of the dam 102. The filter screen 104 is located on the mounting frame 103, and the lifting structure is located on the support base 101. The lifting structure is used to lift the debris blocked by the filter screen 104.

[0029] This utility model mainly includes a support base 101, a gate device, and a filter device. In actual use, the gate device is in the closed state. When it is necessary to open the gate to release water, the gate device needs to be opened. After the gate device is opened, the water is no longer blocked by the gate device and flows to the other side of the gate device. During this process, the impurities in the water are blocked by the filter screen 104 and remain on the lifting structure. The staff can use the lifting structure to lift the impurities blocked by the filter screen 104, thereby completing the cleaning of the impurities. After closing the gate device, the water flow is blocked. During this process, the operation of the gate device and the removal of impurities by the lifting structure do not affect each other. The filtration of the filter screen 104 and the lifting structure work together to make the gate device more effective in use.

[0030] In some embodiments, the gate device includes channel steel 105, gate body 106, and drive structure. The two channel steels 105 are disposed on the inner wall of the dam 102. The left and right ends of the gate body 106 are slidably mounted on the two channel steels 105. The drive structure is mounted on the support base 101 and is used to drive the gate body 106 to move up and down reciprocally in the channel steels 105. The mounting frame 103 is used to be mounted on the channel steel 105 body.

[0031] In actual use, when the gate device is in use, the gate body 106 is first driven to rise by the drive structure. After the gate body 106 rises, the water flows through both sides of the gate body 106. The channel steel 105 is fixedly installed on the inner wall of the dam 102, and the gate body 106 and the channel steel 105 are slidably sealed together.

[0032] In some embodiments, the drive structure includes a screw 107, a bushing 108, and a connecting rod 109. The connecting rod 109 is fixedly mounted on the end face of the gate body 106, the bushing 108 is fixedly mounted on the connecting rod 109, one end of the screw 107 is rotatably connected to the bushing 108, and the other end is threadedly connected to the support seat 101.

[0033] In actual use, the operator rotates the screw 107 to make the screw 107 threadedly connected to the support base 101. Since the bushing 108 is rotatably connected at the end of the screw 107, when the screw 107 is raised, it pulls the gate body 106 to move between the channel steel 105, thereby completing the control of the rise and fall of the gate body 106.

[0034] In some embodiments, a mounting base 110 is provided on the support base 101, and a threaded sleeve 111 is fixedly provided on the mounting base 110. The screw 107 is threadedly connected to the threaded sleeve 111.

[0035] In actual use, the purpose of setting the mounting base 110 is to facilitate increasing the lifting distance of the screw 107 and to install the threaded sleeve 111, so that the screw 107 can better lift the gate body 106.

[0036] In some embodiments, a handwheel 112 is fixedly provided on the screw 107.

[0037] In actual use, the purpose of setting the handwheel 112 is to increase the torque and make it easier for the operator to turn the screw 107.

[0038] In some embodiments, the lifting structure includes a motor 113, a cable reel 114, a steel cable 115, and a sliding plate 116. The sliding plate 116 is used to slide horizontally on the inner wall of the dam 102. A guide plate 117 is inclinedly arranged on the sliding plate 116, and the sliding plate 116 is used to carry debris. A fixing plate 118 is provided on the dam 102. The motor 113 is fixedly installed on the fixing plate 118. The fixing plate 118 is fixedly connected to the support frame. A through hole 119 is provided on the fixing plate 118. The cable reel 114 is fixedly installed on the output shaft of the motor 113. One end of the steel cable 115 is wound on the cable reel 114 and fixedly connected to the cable reel 114. The other end passes through the through hole 119 and is fixedly connected to the sliding plate 116.

[0039] In actual use, when the gate body 106 is opened, the water flow carries debris and garbage along the guide plate 117 onto the slide plate 116. The filter screen 104 blocks the debris. When lifting debris and garbage, the operator drives the motor 113 to rotate. The motor 113 then drives the reel 114 to rotate. The reel 114 then winds the steel cable 115, thereby pulling the slide plate 116. After the slide plate 116 is lifted between the dams 102, the operator removes the debris inside the slide plate 116 and then drives the motor 113 to reverse. The reverse rotation of the motor 113 then drives the reel 114 to release the slide plate 116, thus resetting the slide plate 116. The advantage of this setup is that a storage area can be formed by the guide plate 117, the slide plate 116, the inner wall of the dam 102, and the filter screen 104, allowing the debris to be temporarily stored and then cleaned up after lifting.

[0040] In some embodiments, the slide plate 116 is slidably connected to the inner wall of the dam 102 via a sliding component.

[0041] In actual use, the purpose of setting up the sliding component is to make the sliding plate 116 slide more smoothly against the inner wall of the dam 102.

[0042] In some embodiments, the sliding assembly includes a mounting plate 120 and a sliding track 121. The mounting plate 120 is fixedly installed on the inner wall of the dam 102, and the sliding track 121 is fixedly installed on the mounting plate 120. Sliding recesses are provided on both sides of the sliding plate 116, and the sliding recesses slide in cooperation with the sliding track 121.

[0043] In actual use, the mounting plate 120 is fixedly installed on the inner wall of the dam 102 to facilitate the installation of the sliding rail 121. The sliding recess and the sliding rail 121 also make the sliding between the slide plate 116 and the mounting plate 120 more stable.

[0044] In some embodiments, a guide rod 122 is provided on the bottom surface of the mounting plate 120, and the other end of the guide rod 122 is fixedly connected to the bottom surface of the dam 102. There are several guide rods 122, and the sliding plate 116 is slidably connected to the guide rod 122.

[0045] In actual use, the purpose of setting the guide rod 122 is to further increase the stability of the slide plate 116 when sliding.

[0046] In some embodiments, a railing 123 is provided on the support base 101.

[0047] In actual use, the purpose of setting up the fence 123 is to prevent workers from falling from above the support 101, effectively protecting the personal safety of the workers.
