Description

Technical Field

[0001] The invention belongs to the technical field of gate opening and closing devices, and in particular relates to a gate opening and closing device for a hydropower station. Background Art

[0002] A hydropower station draws water from a high place in a river or other reservoir, and uses the pressure or flow rate of water to drive a turbine to rotate, converting gravitational potential energy and kinetic energy into mechanical energy. The turbine then drives the generator to rotate, converting mechanical energy into electrical energy. A power station is generally composed of four major parts: a water retaining structure (dam), a flood discharge structure (spillway or gate), a water diversion structure (water diversion channel or tunnel, including a surge tank), and a power plant building (including a tailwater channel and a booster station). A hydropower station generally draws water through a gate, which needs to be opened and closed by an opening and closing device.

[0003] After repeated water diversion, the existing hydropower station gate opening and closing device will cause garbage in the water to easily accumulate in the chute of the hydropower station gate base, that is, in the gap between the gate and the gate base. These accumulated garbage need to be manually cleaned, but manual cleaning has great safety issues and is not convenient. Summary of the invention

[0004] The purpose of the present invention is to provide a hydropower station gate opening and closing device to solve the problem that garbage in the chute of the existing hydropower station gate opening and closing device needs to be manually cleaned.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

The water inlet end of the water pump is connected to a water source, the water outlet end of the water pump is connected to the water inlet end of the water supply pipeline, and the multiple water outlet ends of the water supply pipeline are respectively connected to one of the flushing holes to flush the inside of the chute.

[0008] In a possible implementation, the gate flushing assembly also includes an outer shell respectively fixed on both sides of the gate base, a pipeline installation cavity is formed between the outer shell and the gate base, and the water supply pipeline is arranged in the pipeline installation cavity, and the water inlet end of the water supply pipeline passes through the outer shell and is connected to the water outlet end of the water pump.

[0009] In a possible implementation, the water pump is disposed on the top of the gate base.

[0010] In a possible implementation, a one-way valve is provided on each water outlet end of the water supply pipeline.

[0011] In a possible implementation, the flushing hole is provided with a flared portion at one end adjacent to the gate plate;

[0012] A plurality of mounting holes corresponding to the flushing holes are provided along the height direction on one side of the gate plate adjacent to the slide groove, wherein the axial direction of each mounting hole is parallel to the axial direction of the flushing hole, and a constricted portion is provided at one end of the mounting hole adjacent to the flushing hole; a spherical seal and a spring are provided in the mounting hole, and the spherical seal is partially protruded out of the mounting hole by the spring, and the portion of the spherical seal protruding out of the mounting hole abuts against the flared portion for sealing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The hydropower station gate opening and closing device of the present invention is provided with a gate flushing component that can flush the chute between the gate and the gate base. When garbage is accumulated in the chute, water with a certain water pressure can be used through the component to impact the garbage accumulated inside the chute, so that the garbage is separated from the chute, thereby flushing the chute, solving the problem of manual cleaning. It is practical and convenient.

[0020] Moreover, by arranging a steel ball and a spring in the mounting hole on the gate plate, the spring can make part of the steel ball protrude out of the mounting hole and abut against and embed into the flared part, so that the flushing hole can be blocked and sealed to prevent garbage or impurities from entering the flushing hole.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Please refer to Figure 1-3 As shown, an embodiment of the present application provides a hydropower station gate opening and closing device, including a gate plate base 1 with a gate 2, a gate plate 3 arranged in the gate 2, and a driving component for driving the gate plate 3 to rise and fall in the gate 2, and also includes a gate flushing assembly 5, the gate plate 3 is slidably fitted in the gate 2 through a slide groove 6 arranged in the gate 2, and a plurality of flushing holes 55 are provided in the slide groove 6 and along its length direction, and the flushing holes 55 pass through the gate plate base 1 horizontally; the gate is arranged in the gate 2 of the gate base, and can be lifted and lowered along the slide groove 6 under the drive of the driving component. Since garbage or impurities are easily accumulated in the slide groove 6, the garbage in the slide groove 6 can be flushed and removed through the gate flushing assembly 5 in conjunction with the flushing holes 55, thereby solving the problem of manual cleaning.

[0028] The gate flushing assembly 5 includes a water pump 51 and a water supply pipe 52 having a water inlet and multiple water outlets. The water inlet of the water pump 51 is connected to a water source, and the water outlet of the water pump 51 is connected to the water inlet of the water supply pipe 52. The multiple water outlets of the water supply pipe 52 are respectively connected to one of the flushing holes 55 to flush the inside of the chute 6. The water pump 51 can deliver the flushing water source into the flushing hole 55 through the water supply pipe 52, and flush and remove some parts docked in and near the chute 6 through the flushing hole 55, thereby effectively cleaning the accumulated garbage and making the gate opening and closing smoother.

[0029] In one embodiment, the gate flushing assembly 5 also includes a shell 53 respectively fixed on both sides of the gate base 1, a pipeline installation cavity is formed between the shell 53 and the gate base 1, and the water supply pipeline 52 is arranged in the pipeline installation cavity, and the water inlet end of the water supply pipeline 52 passes through the shell 53 and is connected to the water outlet end of the water pump 51.

[0030] In this way, the water supply pipeline 52 can be installed in the shell 53, so that the water supply pipeline 52 is protected and the flushing water source is better transported.

[0031] Specifically, the water pump 51 is disposed on the top of the gate base 1 .

[0032] In order to prevent water near the gate 2 from entering the water supply pipeline 52 through the flushing hole 55, a one-way valve 54 is provided on each water outlet of the water supply pipeline 52. The one-way valve 54 can effectively prevent water near the gate 2 from entering the water supply pipeline 52, thereby affecting normal flushing and cleaning.

[0033] In an embodiment of the present application, a flared portion 56 is provided at one end of the flushing hole 55 adjacent to the gate plate; the diameter of the flared portion 56 is larger than the diameter of the flushing hole 55, and the diameter of the end adjacent to the flushing hole 55 gradually increases toward the diameter of the end adjacent to the gate plate 3. Such a structure can better cooperate with the spherical seal to seal the flushing hole 55.

[0034] In coordination therewith, a plurality of mounting holes 31 corresponding to the flushing holes 55 are provided on one side of the gate plate 3 adjacent to the slide groove 6 along the height direction, and the axial direction of each mounting hole 31 is parallel to the axial direction of the flushing hole 55, and a constricted portion is provided at one end of the mounting hole 31 adjacent to the flushing hole 55; a spherical seal and a spring 32 are provided in the mounting hole 31, and the spherical seal is partially protruded out of the mounting hole 31 by the spring 32, and the portion of the spherical seal protruding from the mounting hole 31 abuts against the flared portion for sealing. In this way, when the gate plate 3 is not in a moving state, the spherical seal can protrude out of the mounting hole 31 through the spring 32, and abut against the flared portion 56 of the flushing hole 55, so as to achieve a blocked seal for the flushing hole 55. This can prevent the flushing water from flowing out through the flushing hole 55 during flushing, and prevent garbage and impurities from entering the flushing hole 55. The spherical seal can also enhance the structural connectivity between the gate plate 3 and the gate plate base 1, thereby improving its lateral impact resistance. When the gate plate 3 is raised and lowered by the driving component, it has basically no effect on it.

[0035] Furthermore, in order to improve the sealing performance between the spherical seal and the expanded portion 56 of the flushing hole 55, a matching sealing ring is provided in the expanded portion 56, and the sealing ring abuts and seals against the portion of the spherical seal protruding from the mounting hole 31. In this way, the spherical seal and the expanded portion 56 of the flushing hole 55 can achieve a better sealing effect.

[0036] Specifically, the spherical sealing element is a steel ball 33; and the sealing ring is a rubber sealing ring.

[0037] In a specific implementation of the embodiment of the present application, the driving component is a hydraulic cylinder 4.

[0038] In a specific implementation of the embodiment of the present application, the water pump 51 is a high-pressure water pump 51.

[0039] In order to improve the corrosion resistance of the shell, the outer surface of the shell 53 is coated with an anti-corrosion layer.
