Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gates for water conservancy projects, and in particular to a lifting gate for water conservancy project design. Background Technology
[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and underground water resources and the environment. Among water conservancy facilities, gates can play a role in intercepting water flow, controlling water level, regulating flow, and discharging sediment and floating debris.
[0003] In the prior art, CN218175776U discloses a lifting hydraulic gate for water conservancy engineering design, which includes a frame. Both sides of the frame have sliding grooves, and a gate panel is slidably connected inside the sliding grooves. Support rods are fixedly connected to both sides of the upper end of the frame, and a top plate is fixedly connected to the upper ends of the two support rods. A lifting mechanism is provided at the lower end of the top plate. A sealing mechanism is provided inside the frame to prevent water leakage from the gate panel. The sealing mechanism includes a moving rod. Moving grooves are provided on both sides of the frame at the rear end of the sliding grooves, and cavities are provided on both sides of the frame at the upper and lower ends. In this solution, when the gate panel descends, the L-shaped rod contacts a protrusion, causing the protrusion to move the moving rod, which in turn moves the sealing plate, ensuring a precise fit between the sealing plate and the gate panel. This method reduces the friction distance between the gate panel and the sealing gasket, improving the sealing effect.
[0004] When in use, the motor drives the screw to raise or lower the door panel. Combined with the sealing mechanism, this reduces the friction distance between the door panel and the sealing gasket, thereby improving the sealing effect. However, when the door panel moves, it slides in the groove and rubs against the groove, which can easily lead to friction with the groove. Over time, this can increase the wear and tear on the door panel and reduce its service life. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lifting hydraulic gate for water conservancy engineering design, so as to solve the technical problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A lifting gate for water conservancy engineering design includes a frame, a lifting gate is provided between two opposite inner side walls of the frame via a lifting component, side grooves are provided on the two opposite inner side walls of the frame, a bottom groove is provided on the bottom side wall of the frame, and sealing components are provided in both side grooves.
[0008] The sealing element includes two side stops, a rubber bladder, a sealing gasket, and a hydraulic chamber. The two side stops are fixedly connected to two opposite side walls within the side groove. The rubber bladder is fixedly connected between the two side stops, with its side connected to the inner side wall of the side groove. The sealing gasket is connected to the side of the rubber bladder near the lifting gate, with a gap between the sealing gasket and the lifting gate. A gap is also left between the side stops and the lifting gate. The hydraulic chamber is fixedly installed within the bottom groove, with the bottom end of the rubber bladder extending into the bottom groove. The end of the hydraulic chamber is connected to the side of the rubber bladder, and the rubber bladder and the hydraulic chamber are interconnected. A pressure-bearing component is provided within the hydraulic chamber.
[0009] In a preferred embodiment, the present invention can be further configured as follows: the lifting component includes two uprights, which are respectively fixedly installed at two ends on the top side of the frame. An installation plate is connected between the top ends of the two uprights. A hydraulic cylinder is connected to the top side of the installation plate. The output end of the hydraulic cylinder passes through the installation plate and is inserted into the lifting gate. A pressing component is provided on the bottom side of the lifting gate.
[0010] In a preferred embodiment, the present invention can be further configured as follows: the pressure-bearing component includes a spring, the spring is fixedly installed on the bottom side wall of the hydraulic chamber, a sliding plate is connected to the top side of the spring, the sliding plate is slidably connected in the hydraulic chamber and is dynamically sealed, a pressure hole is opened on the top side of the hydraulic chamber, a pressure block is slidably connected in the pressure hole, and the bottom side of the pressure block is connected to the sliding plate.
[0011] In a preferred embodiment, the present invention can be further configured such that: the pressing member includes an inner groove, the inner groove is opened in the middle of the bottom side of the lifting gate, a support block is slidably connected in the inner groove, the output end of the hydraulic cylinder extends downward and is fixedly connected to the support block, the position of the support block corresponds to the position of the pressing block, and the shape of the support block is the same as the shape of the pressing block.
[0012] In a preferred embodiment, the present invention can be further configured as follows: two bottom pads are connected to the bottom side wall of the frame, the hydraulic chamber is located between the two bottom pads, the top of the side of the two bottom pads that are close to each other is inclined, and the bottom two opposite sides of the lifting gate are inclined.
[0013] In a preferred embodiment, the present invention can be further configured such that the base pad is made of rubber or silicone, and the side stop is made of rubber or silicone.
[0014] In summary, this utility model has at least one of the following beneficial technical effects:
[0015] 1. The lifting gate for water conservancy engineering design avoids friction with the sealing gaskets on both sides when the lifting gate rises or falls, and also avoids friction between the lifting gate and the side wall of the frame. Only after the lifting gate is closed does its two opposite sides come into contact with the corresponding sealing gaskets to seal, thereby reducing the wear of the sealing gaskets and the lifting gate, and thus improving the service life of the lifting gate.
[0016] 2. In this type of hydraulic engineering design, after the bottom side of the lifting gate is attached to the hydraulic chamber, the hydraulic cylinder continues to extend, thereby pushing the pressure block down. The pressure block causes the sliding plate to slide in the hydraulic chamber, thus compressing the spring. At this time, the hydraulic oil in the hydraulic chamber will be squeezed into the two rubber bladders by the sliding plate. Subsequently, the expansion of the rubber bladders causes the sealing gasket to adhere and contact with the side of the lifting gate, thereby avoiding friction on the lifting gate and the sealing gasket, which would increase wear and reduce service life.
[0017] 3. In this type of hydraulic engineering design, when the hydraulic cylinder extends, it drives the support block to descend. At the same time, the lifting gate will descend due to its own weight. When the lifting gate touches the hydraulic chamber, the hydraulic cylinder continues to extend, causing the support block to touch and push the pressure block. This causes the pressure block to press down the sliding plate, which facilitates the injection of hydraulic oil into the rubber bladder. This allows the rubber bladder to expand and drive the sealing gasket to seal the two opposite sides of the lifting gate.
[0018] 4. In this type of hydraulic engineering design, a lifting hydraulic gate has two bottom pads for fitting against the two opposite sides of the bottom of the lifting gate, so that the corresponding inclined surfaces fit together, thereby sealing the bottom of the lifting gate and preventing impurities or mud in the water from entering the hydraulic chamber, affecting the reset of the sliding plate, and consequently affecting the subsequent extraction of hydraulic oil from the rubber bladder and the reset of the sealing gasket.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example:
[0027] Reference Figures 1-4 The present invention discloses a lifting gate for water conservancy engineering design, including a frame 22. A lifting gate 2 is provided between two opposing inner side walls of the frame 22 through a lifting component 1. Side grooves 3 are provided on the two opposing inner side walls of the frame 22, and bottom grooves 4 are provided on the bottom side wall of the frame 22. Sealing components 5 are provided in both side grooves 3.
[0028] The sealing element 5 includes two side stops 6, a rubber bladder 7, a sealing gasket 8, and a hydraulic chamber 9. The two side stops 6 are fixedly connected to two opposite side walls of the side groove 3, respectively. The rubber bladder 7 is fixedly connected between the two side stops 6, and the side of the rubber bladder 7 is connected to the inner side wall of the side groove 3. The sealing gasket 8 is connected to the side of the rubber bladder 7 near the lifting gate 2, and a gap is left between the sealing gasket 8 and the lifting gate 2. A gap is left between the side stops 6 and the lifting gate 2. The hydraulic chamber 9 is fixedly installed in the bottom groove 4. The bottom end of the rubber bladder 7 extends into the bottom groove 4, and the end of the hydraulic chamber 9 is connected to the side of the rubber bladder 7. The rubber bladder 7 and the hydraulic chamber 9 are interconnected. A pressure-bearing element 10 is provided inside the hydraulic chamber 9.
[0029] In this embodiment, when in use, the frame 22 is embedded in the designated position, and the bottom sidewall inside the frame is exposed; in addition, hydraulic oil needs to be injected into the hydraulic chamber 9 and the rubber bladder 7.
[0030] When it is necessary to close the lifting gate 2, the lifting component 1 drives the lifting gate 2 to descend. After the lifting gate 2 is in contact with the hydraulic chamber 9, the lifting component 1 squeezes the pressure receiving component 10, so that the hydraulic oil in the hydraulic chamber 9 is squeezed and injected into the rubber bladders 7 on both sides. At this time, the hydraulic pressure in the rubber bladder 7 increases, which causes the rubber bladder 7 to expand. When the rubber bladder 7 expands, it pushes the sealing gasket 8 to move towards the side of the lifting gate 2. After the sealing gasket 8 on both sides of the lifting gate 2 comes into contact with it, the squeezing of the pressure receiving component 10 stops, thereby achieving the effect of sealing the side of the lifting gate 2.
[0031] When the lifting gate 2 rises, the lifting component 1 drives the pressure-bearing component 10, causing the hydraulic oil in the rubber bladder 7 to be extracted, thereby restoring the rubber bladder 7 to its original position. At the same time, the sealing gasket 8 is also restored to its original position. Then, the lifting component 1 drives the lifting gate 2 to rise again, achieving the effect of opening the lifting gate 2.
[0032] The gap between the sealing gasket 8 and the lifting gate 2 prevents friction between the lifting gate 2 and the sealing gaskets 8 on both sides when the lifting gate 2 rises or falls, and also prevents friction between the lifting gate 2 and the side wall of the frame 22. Only after the lifting gate 2 is closed does its two sides come into contact with the corresponding sealing gaskets 8 to seal, thereby reducing the wear of the sealing gaskets 8 and the lifting gate 2, and thus improving the service life of the lifting gate 2.
[0033] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, the lifting component 1 includes two uprights 11, which are fixedly installed at the two ends of the top side of the frame 22. A mounting plate 12 is connected between the top ends of the two uprights 11. A hydraulic cylinder 13 is connected to the top side of the mounting plate 12. The output end of the hydraulic cylinder 13 passes through the mounting plate 12 and is inserted into the lifting gate 2. A pressing component 14 is provided on the bottom side of the lifting gate 2.
[0034] In this embodiment, two uprights 11 are used to support the mounting plate 12 and the hydraulic cylinder 13. When the hydraulic cylinder 13 descends, it will drive the lowering member 14 to descend. The output end of the hydraulic cylinder 13 is inserted into the lifting gate 2. Therefore, the output end of the hydraulic cylinder 13 is slidably connected to the lifting gate 2. The lifting gate 2 will descend by its own gravity to facilitate the closing of the lifting gate 2.
[0035] In a further preferred embodiment of this utility model, such as Figure 2-3As shown, the pressure-bearing component 10 includes a spring 15, which is fixedly installed on the bottom side wall of the hydraulic chamber 9. A sliding plate 16 is connected to the top side of the spring 15. The sliding plate 16 is slidably connected within the hydraulic chamber 9 and is dynamically sealed. A pressure hole 17 is provided on the top side of the hydraulic chamber 9. A pressure block 18 is slidably connected within the pressure hole 17. The bottom side of the pressure block 18 is connected to the sliding plate 16.
[0036] In this embodiment, after the bottom side of the lifting gate 2 is attached to the hydraulic chamber 9, the hydraulic cylinder 13 continues to extend, thereby pushing the pressure block 18 down. The pressure block 18 causes the sliding plate 16 to slide in the hydraulic chamber 9, thereby squeezing the spring 15. At this time, the hydraulic oil in the hydraulic chamber 9 will be squeezed by the sliding plate 16 and enter the two rubber bladders 7. Subsequently, the expansion of the rubber bladders 7 causes the sealing gasket 8 to adhere and contact with the side of the lifting gate 2, thereby avoiding friction between the lifting gate 2 and the sealing gasket 8, which would increase wear and reduce service life.
[0037] Additionally, when the lifting gate 2 rises, the lower pressure member 14 is pulled out from the pressure hole 17, and the spring 15 will return to its original shape due to its own elasticity, thereby driving the slide plate 16 and the pressure block 18 back to their original positions. At the same time, the rise of the slide plate 16 will create a negative pressure in the hydraulic chamber 9, thereby drawing the hydraulic oil originally injected into the rubber bladder 7 back into the hydraulic chamber 9, achieving the effect of detaching the sealing gasket 8 from the lifting gate 2.
[0038] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the lower pressing member 14 includes an inner groove 19, which is opened in the middle of the bottom side of the lifting gate 2. A support block 20 is slidably connected in the inner groove 19. The output end of the hydraulic cylinder 13 extends downward and is fixedly connected to the support block 20. The position of the support block 20 corresponds to the position of the pressing block 18, and the shape of the support block 20 is the same as the shape of the pressing block 18.
[0039] In this embodiment, the support block 20 is rectangular, so that when the support block 20 is in the inner groove 19, it can limit the lifting gate 2 and prevent the lifting gate 2 from rotating when it rises or falls, thereby causing it to collide with the side stop bar 6 and thus affecting the fixation of the rubber bladder 7.
[0040] When the hydraulic cylinder 13 extends, it drives the support block 20 to descend. At the same time, the lifting gate 2 will descend due to its own weight. When the lifting gate 2 touches the hydraulic chamber 9, the hydraulic cylinder 13 continues to extend, causing the support block 20 to touch and push the pressure block 18, causing the pressure block 18 to press down the sliding plate 16, thereby facilitating the injection of hydraulic oil into the rubber bladder 7. This allows the rubber bladder 7 to expand and drive the sealing gasket 8 to seal the two opposite sides of the lifting gate 2.
[0041] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, two bottom pads 21 are connected to the inner bottom side wall of the frame 22. The hydraulic chamber 9 is located between the two bottom pads 21. The top of the side of the two bottom pads 21 that are close to each other is inclined. The bottom two opposite sides of the lifting gate 2 are also inclined.
[0042] In this embodiment, two bottom pads 21 are used to fit against the two opposite sides of the bottom of the lifting gate 2, so that the corresponding inclined surfaces fit together, thereby sealing the bottom side of the lifting gate 2 and preventing impurities or mud in the water from entering the hydraulic chamber 9, affecting the reset of the slide plate 16, and thus affecting the subsequent extraction of hydraulic oil from the rubber bladder 7 and the reset of the sealing gasket 8.
[0043] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the bottom pad 21 is made of rubber or silicone, and the side stop bar 6 is made of rubber or silicone.
[0044] In this embodiment, the bottom pad 21 is made of rubber, which has a certain degree of toughness, so that when the lifting gate 2 descends, the bottom pad 21 can fully fit with the lifting gate 2, thereby improving the sealing performance. The side baffle 6 is made of rubber or silicone to prevent the rubber bladder 7 from deforming and thinning when it expands, which could lead to it being punctured when it comes into contact with other debris, thus damaging the rubber bladder 7 and affecting its subsequent use.
[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
