[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example
[0023] like Figures 1 to 5 As shown, this utility model provides a reservoir gate slot anti-clogging device with automatic dredging, including a base 11, which is placed on the gate body 12. An installation slot 13 is pre-cut on the gate body 12, and the base 11 is inserted into the installation slot 13 to achieve initial installation, providing a reliable support foundation for the entire anti-clogging device. A suction hood 14 is provided on the base 11. The suction hood 14 is the key starting point for dredging work, responsible for collecting silt. A crushing component is installed inside the suction hood 14, which crushes larger clumps of silt and various impurities, facilitating subsequent extraction and transportation. The suction hood 14 has two sets of suction columns 15, and two sets of vertical slots are correspondingly cut inside the gate body 12. The two sets of suction columns 15 are respectively inserted into these two sets of vertical slots, and the suction hood 14 and the two sets of suction columns 15 are interconnected, forming a continuous channel to facilitate the flow of silt from the suction hood 14 to the suction columns 15. A sludge pump 16 is installed inside the suction column 15. The sludge pump 16 generates suction to extract the sludge processed by the crushing component. The suction column 15 is also equipped with a top cover 17, which protects the internal components of the suction column 15 and prevents debris from entering. A trolley trough 18 is provided on the gate body 12, and a mobile water tank 19 is placed inside the trolley trough 18 to store the extracted sludge and water.
[0024] like Figures 2 to 3 , Figure 5As shown, the crushing assembly includes a crushing column 21 that penetrates the interior of the suction hood 14. Bidirectional helical blades surround the outer wall of the crushing column 21. When the crushing column 21 rotates, the bidirectional helical blades transport the surrounding sludge to the suction pumps 16 on both sides, simultaneously agitating and crushing it. One end of the crushing column 21 extends out of the suction hood 14, and a driven sprocket is fitted onto this end. A transmission groove 22 is formed on the gate body 12, and the driven sprocket is disposed within the transmission groove 22. Through this arrangement, the driven sprocket can receive externally transmitted power, driving the crushing column 21 to rotate.
[0025] The crushing assembly also includes a support block 23 and a crushing motor 24. The support block 23 is located above the transmission groove 22 and has a through slot that communicates with the transmission groove 22. The crushing motor 24 is mounted on the support block 23, providing power to the crushing assembly. A drive sprocket is fitted onto the shaft end of the crushing motor 24, and the drive sprocket is connected to a driven sprocket located in the transmission groove 22 via a chain drive. When the crushing motor 24 starts, the drive sprocket rotates, driving the driven sprocket through the chain, thereby causing the crushing column 21 to rotate. To protect the crushing motor 24, a protective cover 25 is installed on it. The protective cover 25 prevents the motor from being damaged by external factors and also prevents rainwater from entering the transmission groove 22.
[0026] like Figure 2 , Figure 4 As shown, the mobile water tank 19 is equipped with a filter screen 26, which performs preliminary filtration of the sludge transported from the sludge pump 16, separating out larger impurities. A cover 27 is installed on top of the filter screen 26, which seals the mobile water tank 19 to prevent the sludge and water inside from overflowing. The cover 27 has two sets of connection ports, which are connected to the sludge pump 16 via pipes, allowing the sludge and water pumped out by the sludge pump 16 to flow smoothly into the mobile water tank 19.
[0027] Multiple sets of casters are installed at the bottom of the mobile water tank 19, and a pusher is also provided on one side of the mobile water tank 19, which makes it easy to transport silt. A drain outlet 28 is provided on one side of the mobile water tank 19, and a filter block 29 is installed inside the drain outlet 28. The filter block 29 can further filter the discharged water and reduce impurities in the water. A guide plate is provided on one side of the drain outlet 28, which can guide the discharged water flow towards the reservoir water body and prevent water from splashing everywhere.
[0028] The trolley trough 18 is U-shaped, which provides good accommodation and guidance for the mobile water tank 19. A limiting block 33 is provided at the U-shaped opening of the trolley trough 18. The limiting block 33 is trapezoidal, and the mobile water tank 19 is locked on one side of the limiting block 33. The limiting block 33 can restrict the movement range of the mobile water tank 19 in the trolley trough 18 and prevent it from falling out of the trolley trough 18.
[0029] like Figures 2 to 3 As shown, the suction hood 14 is equipped with a suction grid 31, which can block larger debris from entering the suction hood 14, and also helps to guide water flow and silt into the suction hood 14. Multiple sets of pressure blocks 32 are set below the gate 34. The pressure blocks 32 are inserted into the suction grid 31. The weight of the gate 34 can squeeze and break the strip-shaped debris such as tree branches stuck on the suction grid 31, making it easier to suck into the suction hood 14 and improving the suction effect.
[0030] The specific usage and function of this embodiment are as follows:
[0031] When using the reservoir gate slot anti-clogging device with automatic sludge removal, the crushing motor 24 is started, and the crushing column 21 is rotated through the chain drive between the driving and driven sprockets. The bidirectional spiral blades on its outer wall crush and agitate the sludge in the suction hood 14. At the same time, the sludge pump 16 is started to generate suction, and the crushed sludge is transported through the pipeline to the mobile water tank 19, where the filter screen 26 performs preliminary filtration.
[0032] The casters beneath the mobile water tank 19 allow it to move in various environments, facilitating better transport of silt. The filter block 29 at the drain outlet 28 further filters the discharged water, and the guide plate directs the water flow. The suction grille 31 blocks large debris. The limiting block 33 prevents the mobile water tank 19 from detaching from the trolley trough 18. The entire device works in concert to achieve automatic silt removal from the reservoir gate slot, preventing blockages and ensuring the normal operation of the gate.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
