Technical Field
[0001] The present invention relates to the technical field of water conservancy projects, and more specifically, to a lifting water conservancy gate used in water conservancy project design. Background Art
[0002] Water conservancy project design is the work of formulating engineering plans, buildings, implementation methods, and budgets to achieve certain water conservancy goals. Lifting water conservancy gates are the most common facilities in water conservancy project design. The main functions of water conservancy gates include regulating upstream water levels, controlling downstream flow, and protecting the safety of downstream buildings and channels. However, existing lifting water conservancy gates have the following shortcomings: when the gate intercepts the water flow, impurities in the water flow will settle and accumulate at the lower end of the gate, causing the gate to jam when it is raised and lowered, reducing the effectiveness of the gate. In addition, the gate needs to be opened and lowered manually, and the water level upstream of the interception cannot be monitored. When the water level upstream of the interception is high, the flow cannot be automatically discharged in time, causing the gate to be damaged by a large water pressure shock.

At this time, the control box remotely sends the water level data to the management end, reminding the management personnel to pay attention to the water level to prevent the water level from rising suddenly. When the water level sensor above detects the water level, it means that the water level is about to exceed the highest point of the gate. While reminding the management personnel, the control box starts the micro water pump to extract the water source in front of the gate to lower the water level in front of the gate, and automatically discharge the water in time to prevent the gate from being damaged by large water pressure impact.

DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the accompanying drawings: Example

When the pull rope 514 is tightened, it drives the front end of the filter plate 51 to tilt upward to filter and collect the garbage accumulated at the lower end of the gate 5. The surface of the rope roller 515 is also embedded with an anti-slip ring 5154 to increase the friction between it and the pull rope 514. The rear end of the gate 5 is also equipped with a guide mechanism 5152, and the guide mechanism 5152 consists of a guide ring 1621, a roller 1622 and a brake pad 1623. The connecting rod 5151 is inserted into the guide ring 1621 by a clearance fit, and the roller 1622 provided on the inner side of the guide ring 1621 assists the connecting rod 5151 in rotating, and the brake pad 1623 provided on the inner side of the guide ring 1621 brakes the connecting rod 5151. The middle part of the outer side of the brake pad 1623 is connected to the linkage support rod 6231, and the outer end of the linkage support rod 6231 is provided with an adsorption wheel 6232. The outer side of the adsorption wheel 6232 is provided with an inner side of a guide frame 6233, and the adsorption wheel 6232 slides along the inner side of the guide frame 6233 under the magnetic adsorption of the electromagnetic sheet 6235 provided inside the guide frame 6233. A compression spring 6234 is provided between the electromagnetic sheet 6235 and the adsorption wheel 6232 for the adsorption wheel 6232 to be clamped. 232 provides a reset elastic force, the side of the gate 5 is also provided with a scraper plate 54, and the upper end of the scraper plate 54 is provided with a torsion shaft 541 elastically connected to the inside of the gate 5, the inner side of the lower end of the scraper plate 54 is welded with a top spring 542, and the other end of the top spring 542 is elastically squeezed inside the side of the gate 5, the upper end of the gate 5 is also provided with a control box 52, and the power box 6 provides power to the control box 52, the control box 52 is electrically connected to the water level sensor 521 above the front end of the gate 5, the front end of the gate 5 is also provided with an extraction pipe 53, and the upper end of the extraction pipe 53 is installed with a micro water pump 531, and the micro water pump 531 is controlled and connected through the control box 52, the rear end of the extraction pipe 53 is provided with a drainage head 532, and the drainage head 532 is installed at an inclined angle. In the present invention,The power box 6 is used to provide power to the gate hoist 3 so that the gate hoist 3 can be started to drive the screw 4 to rotate and lift. Under the connection of the connecting frame 41, the gate 5 is driven to lift and lower inside the gate frame 1 to adjust the upstream water level and control the downstream flow. Before the gate 5 rises, the two connecting rods 5151 are synchronously driven by starting the dual-axis motor 5153 to drive the two rope rollers 515 to rotate and reel in the pull rope 514. At this time, the front end of the pull rope 514 pulls the front end of the filter plate 51 to tilt upward to filter the impurities that have settled and accumulated at the lower end of the gate 5. After the front end of the filter plate 51 tilts upward, the side baffles 512 on both sides are attached to the front end of the gate 5 to block the impurities and prevent the impurities from falling into the water flow again during the rising process of the gate 5. During the process, the scraper plates 54 on both sides elastically swing around the torsion shaft 541 to scrape the inner wall of the gate frame 1. When the gate 5 descends to intercept the upstream water level, if the water level rises to the water level sensor 521 below, the lower water level sensor 521 detects the water level. At this time, the control box 52 remotely sends the water level data to the management end, reminding the management staff to pay attention to the water level situation to prevent a sudden rise in the water level. When the upper water level sensor 521 detects the water level, it means that the water level is about to exceed the highest point of the gate 5. At the same time, the control box 52 starts the micro water pump 531 to pump water from the water source in front of the gate 5 to lower the water level in front of the gate 5, and automatically releases water in time to prevent the gate 5 from being damaged by the large water pressure impact.
[0018] A preferred technical solution is that two rope winding rollers 515 and two connecting rods 5151 are provided. The two rope winding rollers 515 are synchronously driven by a dual-axis motor 5153 to rotate and synchronously tighten the pull ropes 514 on both sides, ensuring that the front ends of the filter plates 51 are stably tilted upwards, and cooperate with the side baffles 512 on both sides of the upper end of the filter plates 51 to block impurities and prevent them from falling into the water flow again. In a preferred technical solution, two linkage rods 6231, adsorption wheels 6232, guide frames 6233, compression springs 6234, and electromagnetic plates 6235 are each provided and symmetrically installed in an upper and lower direction. When the pull rope 514 tightens the front end of the filter plate 51 and tilts it upward to filter impurities, the two electromagnetic plates 6235 are energized synchronously to generate magnetic attraction on the two adsorption wheels 6232, driving the two linkage rods 6231 to move in conjunction, thereby pushing the brake pads 1623 to squeeze and frictionally brake the connecting rod 5151, preventing the rope roller 515 from reversing after tightening the pull rope 514, causing the filter plate 51 to flip down and causing impurities to fall into the water flow again. A preferred technical solution is that the scraper plates 54 are provided with six, and three in a group, respectively provided on the left and right sides of the gate 5. Under the elastic force applied by the torsion shaft 541 and the top spring 542, the scraper plates 54 are ensured to be able to elastically swing around the torsion shaft 541, thereby scraping the inner wall of the gate frame 1 during the lifting and lowering process of the gate 5, scraping off impurities on the inner wall of the gate frame 1, improving the smoothness of the lifting and lowering of the gate 5 inside the gate frame 1, thereby improving the effect of the gate frame 1 and the gate 5 cooperating to intercept the water flow; A better technical solution is that there are two water level sensors 521, and they are installed at high and low positions on the same vertical line on the front surface of the gate 5. When the water level sensor 521 below detects the water level, the control box 52 remotely sends the water level data to the management end, reminding the management personnel to pay attention to the water level to prevent the water level from rising suddenly; there are two extraction pipes 53 and two micro water pumps 531, and the two micro water pumps 531 are controlled and connected by the control box 52. When the water level sensor 521 above detects the water level, it means that the water level is about to exceed the highest point of the gate 5. At this time, the control box 52 starts the micro water pump 531, extracts the water source in front of the gate 5 to lower the water level at the front end of the gate 5, and automatically discharges the water in time to prevent the gate 5 from being damaged by a large water pressure shock.
