[0002] Water conservancy engineering is an engineering discipline involving the planning, design, construction, management and maintenance of water resources. Its purpose is to effectively utilize water resources to ensure the needs of human life and economic activities, while preventing floods and protecting the environment. Water conservancy projects include various projects and facilities involving water collection, storage, distribution, transportation, and discharge. During the operation of water conservancy projects, in order to accurately adjust the water level according to different needs, it is necessary to use lifting gates to achieve flexible adjustment of reservoir water levels and rational allocation of water resources.

[0003] In the existing technology, there are the following defects; traditional lifting water conservancy project gates often face some problems during use. For example, the gap between the side water stop of the gate and the side wall of the gate slot is easily blocked by foreign objects such as branches, weeds, and plastic garbage. After these foreign objects enter the gap with the water flow, they will hinder the normal lifting of the gate. At the same time, the contact between the bottom of the gate and the bottom of the gate slot may also be accumulated by stones, mud and sand, making it impossible for the gate to fall completely or encounter greater resistance when rising. These problems not only affect the normal operation of the water conservancy project, but also increase maintenance costs and safety risks. For this reason, a lifting water conservancy project gate for water conservancy projects is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment of a lifting type water conservancy project gate, comprising a gate frame 1, the top of the gate frame 1 is fixedly connected to a top frame 15, the top frame 15 mainly supports and connects the hydraulic telescopic rod 2, the bottom end of the top frame 15 is provided with a hydraulic telescopic rod 2, the hydraulic telescopic rod 2 uses the hydraulic principle to realize a mechanical device of linear motion, which is a prior art, and the gate 3 can be opened or closed by the hydraulic telescopic rod 2. The movable end of the hydraulic telescopic rod 2 is fixedly connected to the gate 3, the inner wall of the right end of the gate frame 1 is elastically connected to the movable rod 5 by a return spring 4, and the left end of the movable rod 5 is fixedly connected to the L frame 6, the L frame 6, the movable rod 5, the extrusion rod 9 and the wedge 8 are all made of steel and have a strong bearing capacity. The end of the L frame 6 is fixedly connected to a filter plate 7, and a filter screen is provided on the filter plate 7, which can prevent impurities from entering the gate slot of the gate frame 1. The outer wall of the gate 3 is provided with a squeezing mechanism, and the inner wall of the top of the gate frame 1 is provided with a buffer component.

[0031] Reference Figure 2-Figure 4The buffer assembly includes a sleeve 10, which contains liquid, and the liquid is almost full of the sleeve 10. There is a certain space to meet the flow of liquid. The top of the sleeve 10 is elastically connected to the piston tube 12 through a positioning spring 11. The bottom end of the piston tube 12 is provided with a circular hole 13. During the movement of the piston tube 12, the liquid can pass through the circular hole 13. The top of the piston tube 12 is fixedly connected to a buffer plate 14. The top of the buffer plate 14 is made of anti-corrosion rubber material, which can alleviate the impact through the rubber material. The top of the sleeve 10 is fixedly connected to one end of the positioning spring 11. At this time, the positioning spring 11 is in a compressed state. When resetting, the positioning spring 11 will bring the piston tube 12 back to normal. The other end of the positioning spring 11 is fixedly connected to the inner side wall of the piston tube 12. The piston tube 12 passes through and the piston is connected to the inner wall of the sleeve 10. The top of the buffer plate 14 contacts the bottom end of the gate 3.

[0032] Reference Figure 1-Figure 3 The inner wall of the right end of the gate frame 1 is fixedly connected to one end of the return spring 4. At this time, the return spring 4 is in a stretched state. When resetting, the elastic force of the return spring 4 is used to reset the movable rod 5. The other end of the return spring 4 is fixedly connected to the right end of the movable rod 5. The movable rod 5 is slidably connected to the inner wall of the gate frame 1. The extrusion mechanism includes an extrusion rod 9, which is fixedly connected to the outer wall of the gate 3. The bottom end of the extrusion rod 9 contacts a wedge 8, which is inclined. At this time, the extrusion rod 9 is located at the lowest point of the inclined surface of the wedge 8. When the extrusion rod 9 no longer contacts the wedge 8, the extrusion rod 9 is located at the highest point of the inclined surface of the wedge 8. The wedge 8 is fixedly connected to the top of the L frame 6, and the side wall of the filter plate 7 contacts the inner side wall of the gate frame 1.

[0033] Working principle: First, when the gate 3 is opened, the hydraulic telescopic rod 2 will be driven by electric control to move the gate 3 and the squeezing rod 9 upward. When the squeezing rod 9 is no longer in contact with the inclined surface of the wedge block 8, the impact force of the water and the reverse elastic force of the return spring 4 will be used to allow the movable rod 5 to move the L frame 6, the wedge block 8 and the filter plate 7 to the right, so that the filter plate 7 is located above the gate slot of the gate frame 1, and the filter plate 7 is used to block impurities to prevent impurities from entering the gate slot and affecting the closing of the gate 3. When the gate 3 is closed, the hydraulic telescopic rod 2 will move the gate 3 and the squeezing rod 9 downward, so that the squeezing rod 9 squeezes the inclined surface of the wedge block 8, and the wedge block 8 moves the L frame 6, the movable rod 5 and the filter plate 7 to the left and stretch the return spring 4, so that the filter plate 7 returns to its initial state and no longer blocks the filtration of the gate slot.

[0034] When the gate 3 rises and slowly leaves the gate slot of the gate frame 1, the reverse elastic force of the positioning spring 11 will slowly restore the piston tube 12 and the buffer plate 14 to their original position in the gate slot. When the gate 3 is closed, the buffer plate 14 will contact the bottom end of the gate 3 to relieve part of the impact. The gate 3 will squeeze the buffer plate 14 to allow the piston tube 12 to move downward. Since the aperture of the circular hole 13 is small, the bottom end of the piston tube 12 will continuously squeeze the water in the sleeve 10 to produce a buffering effect. During the compression process, the buffer plate 14 will also relieve part of the impact due to its own elastic force, thereby reducing the impact of the rapid descent of the gate 3 on the gate 3.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
