[0033] 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.
[0034] Reference Figures 1-2 This utility model provides an embodiment of a gate for water supply and drainage engineering, including a support 1, a lifting device 2 at the upper end of the support 1, and a gate body 3 at the bottom end of the lifting device 2. The gate body 3 is slidably connected to the inside of the support 1, which can guide and limit the movement of the gate body 3, so that the gate body 3 can only perform linear movement in the up and down direction. The lifting device 2 includes a motor and a lead screw. When the motor is started, the lead screw can drive the gate body 3 to perform linear movement in the up and down direction under the limitation of the inner wall of the support 1, thereby controlling the water flow discharge.
[0035] Reference Figures 3-5 An L-shaped fixing bracket 4 is fixedly connected to the front surface of the gate body 3. The left and right sides of the L-shaped fixing bracket 4 are in contact with the inner surfaces of the left and right sides of the bracket 1. An elastic element 5 is fixedly connected to the top surface inside the L-shaped fixing bracket 4. A connecting plate 6 is fixedly connected to the bottom end of the elastic element 5. When the connecting plate 6 moves upward, it can squeeze the elastic element 5, causing the elastic element 5 to compress and generate elastic potential energy. A protective plate 7 is detachably connected to the bottom end of the connecting plate 6. When the protective plate 7 moves, it can drive the connecting plate 6 to move synchronously. The inner wall of the protective plate 7 is in contact with the inner wall of the L-shaped fixing bracket 4. The protective plate 7 and the L-shaped fixing bracket 4 can seal and protect the elastic element 5, preventing impurities in the water flow from entering the elastic element 5 and affecting its use. The back of plate 7 is in contact with the front surface of gate body 3. In the initial state, gate body 3 is at the bottom of support 1 to cut off the water flow. At this time, the bottom of support 1 can squeeze the protective plate 7 and squeeze the elastic element 5. When gate body 3 moves upward to open the flow channel, the protective plate 7 can move downward relative to gate body 3 under the elastic potential energy of elastic element 5, thereby blocking the bottom of gate body 3. This prevents the water flow from flowing to the rear along the bottom front of gate body 3 during the upward movement of gate body 3, which would cause the water flow to contact and wear the bottom front of gate body 3. As a result, the bottom front of gate body 3 will become thinner and thinner during long-term use, thus affecting the service life of gate body 3.
[0036] A protective unit is provided at the bottom of the protective plate 7. The protective unit includes a rounded corner 71, which is located at the front end of the bottom surface of the protective plate 7. The water flow can flow along the arc surface of the rounded corner 71, reducing the impact of the water flow on the bottom of the protective plate 7 and thus extending the service life of the protective plate 7. A rectangular groove 72 is provided at the rear end of the bottom surface of the protective plate 7. Through the cooperation of the rectangular groove 72 and the rounded corner 71, the bottom end of the protective plate 7 is set with a pointed structure. When the gate body 3 moves downward, the protective plate 7 can first contact the inner bottom surface of the support 1. The pointed structure at the bottom end of the protective plate 7 can prevent impurities from accumulating below the protective plate 7. A protective unit is provided at the bottom end of the front surface of the protective plate 7. The L-shaped channel 73 runs through the protective plate 7. The front side of the protective plate 7 and the inner wall of the rectangular channel 72 are connected through the L-shaped channel 73. When impurities accumulate inside the rectangular channel 72 or below the gate body 3, affecting the tight fit of the gate body 3, the water flow can flow through the L-shaped channel 73 into the interior of the rectangular channel 72 to flush away the impurities, thus preventing the accumulation of impurities from affecting the complete closure of the gate body 3. A filter cloth 74 is provided on the front surface of the protective plate 7. The filter cloth 74 is located at the front end of the L-shaped channel 73. The filter cloth 74 can filter the water flow to prevent impurities in the water flow from entering the L-shaped channel 73 and causing blockage.
[0037] A guide unit is provided on the back of the protective plate 7. The guide unit includes a reinforcing rib 81, which is fixedly connected to the front surface of the gate body 3. The reinforcing rib 81 can enhance the overall strength of the gate body 3. A guide groove 82 is provided on the back of the protective plate 7. The outer wall of the reinforcing rib 81 fits against the inner wall of the guide groove 82. The reinforcing rib 81 and the guide groove 82 are slidably connected. The movement of the protective plate 7 can be guided and limited by the cooperation of the reinforcing rib 81 and the guide groove 82, so as to prevent the protective plate 7 from deflecting under the scouring of water flow and affecting its movement.
[0038] Reference Figures 6-7 The upper surface of the protective plate 7 has a slot 9, and the inner front wall of the slot 9 has a groove 10. The bottom end of the connecting plate 6 is fixedly connected to the plug 11, which is inserted into the slot 9. The plug 11 can be directly pulled out of the slot 9. The front surface of the plug 11 has a groove 12, and the back of the groove 12 is fixedly connected to the inside. The front end of the spring 13 is fixedly connected to the plug 14. When the plug 14 moves toward the spring 13, it can squeeze the spring 13, causing the spring 13 to compress and generate elastic potential energy. The front end of the plug 14 engages with the inside of the groove 10, and the outer wall of the plug 14 fits against the inner wall of the groove 12. When the protective plate 7 is worn after long-term use and needs to be replaced, the operator can push the plug 14 into the groove 12 to engage and fix the protective plate 7, and then move the protective plate 7 downward to remove it for replacement. The operation is simple and the replacement is quick.
[0039] Working principle: When the gate body 3 moves upward to open, the protective plate 7 can move downward relative to the gate body 3 under the elastic potential energy of the elastic element 5. This allows the protective plate 7 to protect the bottom of the gate body 3, preventing direct contact between the water flow and the gate body 3, which would cause the bottom of the gate body 3 to be eroded by the water flow and become thin, affecting the service life of the gate body 3. When the gate body 3 moves downward to close, the protective plate 7 can first filter the water flow and allow the water flow to flush away the impurities accumulated at the bottom of the gate body 3, preventing the accumulation of impurities from affecting the complete closure of the gate body 3.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
