Description

Technical Field

[0001] This utility model relates to the field of gate technology, specifically a water conservancy engineering gate with a filter function. Background Technology

[0002] In water conservancy projects, sluice gates are mainly used to control water levels, regulate flow, and prevent floods and remove sediment. For example, in reservoirs, sluice gates can adjust water levels as needed to ensure reservoir safety and optimize water resource utilization; in rivers, sluice gates help regulate river flow and prevent natural disasters such as floods. The sluice gates are raised and lowered via screws and actuators.

[0003] Currently, although water can flow after the gate is opened, the water flowing through the gate in water conservancy projects carries certain impurities, resulting in serious water pollution. Although the filter screen installed at the gate can filter impurities in the water flow, the impurities remain on one side of the filter surface, causing blockage of the gate's flow and reducing the gate's flow capacity. Moreover, cleaning the filter screen in the water is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic engineering gate with a filtration function to solve the problems mentioned in the background art.

[0023] Specifically, the cleaning mechanism 7 includes a cleaning frame 71, a scraper 72, a first filter plate 73, and a second filter plate 74. The bottom of the connecting plate 6 below the brush 8 is equipped with a cleaning frame 71. The side of the cleaning frame 71 closest to the filter screen 3 is equipped with a scraper 72. The side of the cleaning frame 71 away from the filter screen 3 is equipped with a first filter plate 73. The side of the cleaning frame 71 away from the first filter plate 73 is equipped with a second filter plate 74. The end of the scraper 72 away from the first filter plate 73 is in contact with the filter surface of the filter screen 3. The scraper 72 moves from bottom to top to clean the filter surface. The impurities generated by the filtration and removal of impurities on one side of the filter surface of the filter screen 3 are cleaned onto the first filter plate 73 and the second filter plate 74.

[0024] Furthermore, an mounting plate 51 is provided on the upper end of one side of the gate body 4 above the filter screen 3. The connecting bracket 5 is fixedly installed to the mounting plate 51 by bolts. The connecting plate 6, which carries the brush 8 and the cleaning mechanism 7, is easy to disassemble and install on the gate body 4 and is firmly installed.

[0025] Furthermore, limit seats 10 are provided on the gate frame 1 on both sides inside the gate opening 2, and limit grooves 11 are provided on both sides of the gate body 4. The limit seats 10 are slidably disposed inside the limit grooves 11.

[0026] Furthermore, the scraper 72 is configured with a triangular prism structure, and the end of the scraper 72 near the filter screen 3 is inclined upwards.

[0027] Furthermore, both the No. 1 filter plate 73 and the No. 2 filter plate 74 are provided with evenly distributed filter holes. The No. 1 filter plate 73 is set in a horizontal structure, and the end of the No. 2 filter plate 74 away from the No. 1 filter plate 73 is set at an angle upward. The No. 2 filter plate 74 can block the outward diffusion of impurities.

[0028] Furthermore, there are two filter screens 3, which are installed on the gate frame 1 of the gate openings 2 on opposite sides of the gate body 4. The upper ends of the gate body 4 on opposite sides are provided with mounting plates 5, which can filter impurities at the gate openings 2 on both sides of the gate body 4.

[0029] The usage method of this embodiment is as follows: The screw 9 on the gate body 4 cooperates with the gate actuator, and the gate body 4 rises and falls within the gate opening 2 of the gate frame 1. The limit seat 10 slides within the limit groove 11, which is used for controlling water level and regulating flow in water conservancy projects. A filter screen 3 is set on the gate frame 1 of the gate opening 2. The filter screen 3 filters and removes impurities from the flowing water. Impurities in the water are blocked and retained on one side of the filter surface by the filter screen 3. When cleaning the filter screen 3, the gate body 4 is first moved down to a low position, and the gate opening 2 is closed. The connecting frame 5 is fixed to the mounting plate 51 at the upper end of the gate body 4 by bolts. That is, the connecting plate 6 carrying the brush 8 and the cleaning mechanism 7 is fixedly installed on the gate body 4. Then, the gate actuator drives the gate body 4 to move within the gate through the screw 9. The inlet 2 moves upward, and the connecting plate 6 drives the brush 8 and cleaning mechanism 7 to move from bottom to top on the filter surface of the filter screen 3. The brush 8 and scraper 72 clean the filter surface of the filter screen 3, and clean the impurities generated by the filtration of the filter screen 3 to the first filter plate 73 and the second filter plate 74. Since the second filter plate 74 is tilted upward, it can prevent the impurities from spreading outward. The first filter plate 73 and the second filter plate 74 move upward and are exposed above the water surface. The impurities on the first filter plate 73 and the second filter plate 74 are cleaned at a higher position. The cleaning mechanism 7 and the brush 8 move up and down synchronously with the gate body 4 to facilitate the cleaning of the filter surface of the filter screen 3 and ensure smooth water flow at the gate. The first filter plate 73 and the second filter plate 74 are easy to clean and collect.
