Description

Technical Field

[0001] This utility model relates to the field of flood control gate technology, specifically an automatic flood control gate for reservoir scheduling. Background Technology

[0002] Reservoir management utilizes the reservoir's storage capacity to systematically store and release inflows based on actual water levels and hydrological forecasts. While ensuring engineering safety, management is conducted according to the reservoir's primary and secondary functions, adhering to the principle of comprehensive water resource utilization, to achieve flood control and water resource benefits, and to maximize the satisfaction of the needs of various sectors of the national economy.

[0003] Automatic floodgates are needed for reservoir operation. Existing floodgates are generally low-head hydraulic structures built on rivers and canals to control flow and regulate water levels. Closing the gates can impound floodwaters, block tides, or raise upstream water levels to meet the needs of irrigation, power generation, navigation, aquaculture, environmental protection, industry, and domestic water use. Opening the gates can release floodwaters, waterlogged water, wastewater, or polluted water, and can also supply water to downstream rivers or canals. In water conservancy projects, floodgates are widely used as structures for impounding, releasing, or drawing water. Because floodgates are installed on rivers and canals, when the gate is open, silt and impurities from the river and canal can easily enter the groove of the gate base. When the gate is closed, these silt and impurities come into contact with the groove of the base, thus affecting the seal between the gate and the overall frame. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic flood control gate for reservoir scheduling to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic flood control gate for reservoir scheduling, comprising a frame, a positioning sealing groove opened inside the frame, and a gate plate located in the cavity of the positioning sealing groove.

[0020] 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.

[0021] Please see Figures 1-3 This utility model provides an automatic flood control gate for reservoir scheduling, including a frame 1, a positioning sealing groove 2 opened inside the frame 1, and a gate plate 3 located inside the positioning sealing groove 2. The lower part of the frame 1 is provided with a silt cleaning component 4, which includes an installation groove 41. The installation groove 41 is opened at the lower front side of the frame 1. A telescopic rod 42 is fixedly installed on the rear side of the inner cavity of the installation groove 41. A circular plate 43 is fixedly installed on the front side of the telescopic rod 42. A spring 44 is movably sleeved on the outer side of the telescopic rod 42. The two ends of the spring 44 are respectively fixedly installed on the rear side of the inner cavity of the installation groove 41 and the rear side of the circular plate 43. A connecting rod 45 is fixedly installed on the front side of the circular plate 43. A cleaning plate 46 located inside the positioning sealing groove 2 is fixedly installed on the rear side of the connecting rod 45. The bottom of the gate plate 3 and the top of the cleaning plate 46 are both inclined surfaces. A cleaning plate 46 is provided below the gate plate 3. When the gate plate 3 moves downward, it moves to a position that contacts the top of the cleaning plate 46, pushing the cleaning plate 46 towards the front of the frame 1. This facilitates the removal of impurities and sludge accumulated at the bottom of the positioning sealing groove 2 from the front of the positioning sealing groove 2, thus preventing impurities and sludge at the bottom of the positioning sealing groove 2 from affecting the sealing performance between the gate plate 3 and the frame 1.

[0022] The cleaning plate 46 is equipped with symmetrically distributed connecting rods 45, circular plates 43, springs 44, and telescopic rods 42 on both sides. This allows the cleaning plate 46 to move stably within the positioning and sealing groove 2.

[0023] In its free state, the rear side of the cleaning plate 46 is in contact with the rear side of the inner cavity of the positioning sealing groove 2. This facilitates the squeezing of the cleaning plate 46 when the gate plate 3 moves downward, and at the same time, it can clean impurities and silt from the bottom of the inner cavity of the positioning sealing groove 2.

[0024] The gate plate 3 is equipped with a height adjustment component 5 at its top. The height adjustment component 5 includes a moving groove 51, a square groove 52, a float plate 53, and a connecting plate 54. The moving groove 51 and the square groove 52 are respectively opened on the front and rear sides of the top of the gate plate 3. The float plate 53 and the lifting plate 55 are movably fitted into the inner cavity of the moving groove 51 and the inner cavity of the square groove 52, respectively. The float plate 53 and the lifting plate 55 are connected by the connecting plate 54. With the height adjustment component 5 on the gate plate 3, when the water level rises, the float plate 53 will move upward with the water level, and the connecting plate 54 will drive the lifting plate 55 to move upward. This makes it easier to raise the gate plate 3 when the water level rises, thus facilitating the isolation of rivers with different water levels.

[0025] Both sides of the front of the lifting plate 55 are equipped with float plates 53 and connecting plates 54. These provide sufficient buoyancy for the lifting plate 55 to move upward.

[0026] A grid 6 is fixedly installed on the front side of the moving tank 51, located in front of the float 53. By setting the grid 6, impurities in the water are prevented from entering the moving tank 51 and affecting the movement of the float 53.

[0027] The top of the gate plate 3 is provided with a threaded groove 9, and a motor 7 is fixedly installed on the top of the frame 1. The output end of the motor 7 is fixedly installed with a lead screw 8 that is threadedly connected to the threaded groove 9. The motor 7 drives the lead screw 8 to rotate. Due to the threaded connection between the gate plate 3 and the lead screw 8, the gate plate 3 moves along the inner cavity of the positioning sealing groove 2, which facilitates automatic control of the opening and closing of the gate plate 3.

[0028] Working principle: When using this device, the motor 7 drives the lead screw 8 to rotate. Due to the threaded connection between the gate plate 3 and the lead screw 8, the gate plate 3 moves along the inner cavity of the positioning sealing groove 2, and the opening and closing of the gate plate 3 is automatically controlled.

[0029] When the motor 7 drives the gate plate 3 to move downward, the bottom of the gate plate 3 moves to a position that contacts the top of the cleaning plate 46. Utilizing the shape characteristics between the bottom of the gate plate 3 and the top of the cleaning plate 46, the cleaning plate 46 is pushed towards the front of the frame 1, pushing out the impurities and sludge accumulated at the bottom of the positioning sealing groove 2 from the front of the positioning sealing groove 2. This prevents the impurities and sludge at the bottom of the positioning sealing groove 2 from affecting the sealing performance between the gate plate 3 and the frame 1. The cleaning plate 46 is pushed to the front of the gate plate 3, thereby sealing the connection between the gate plate 3 and the positioning sealing groove 2.

[0030] When the water level rises, the float plate 53 will move upward with the water level, and the connecting plate 54 will drive the lifting plate 55 to move upward, thereby raising the gate plate 3 when the water level rises.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
