Description

Technical Field

[0001] The present invention relates to the technical field of hydropower station gates, and particularly to a locking device for a hydropower station gate. Background Art

[0002] In order to accelerate the development of western water resources and realize the transmission of electricity from west to east, a hydropower plant, also known as a hydroelectric power plant, is a factory that converts the potential energy and kinetic energy of water into electrical energy. Its basic production process is to divert water from a high place in a river or other reservoirs, use the pressure or flow rate of water to impulse the rotation of a water turbine, convert the gravitational potential energy and kinetic energy into mechanical energy, and then the water turbine drives the generator to rotate to convert the mechanical energy into electrical energy. The hydropower station gate is one of the important equipment of the hydropower station, mainly used for controlling water flow, regulating water level, preventing water flow backflow and closing emergently in case of accidents. The hydropower station gate can be divided into valve types such as flat gates and arc gates;

[0003] An arc gate is a gate with a part of the arc surface of the cylinder as the water retaining surface. The supporting hinge of its supporting arm is located at the center of the circle. When opening and closing, the gate rotates around the supporting hinge. The arc gate is composed of a rotating gate body, embedded components and opening and closing equipment. Before opening the valve, it is necessary to pay attention to the changes in the water levels upstream and downstream and the water flow pattern, and at the same time pay attention to whether there are ships or other floating objects approaching in front of the gate to prevent possible gate impact events. However, when the gate is just opened, the water flow impact is large. During the operation of the gate, the water flow impact causes the gate to vibrate, resulting in the gate cracking. For this reason, we propose a locking device for a hydropower station gate. Summary of the Invention

[0004] The purpose of the present invention is to provide a locking device for a hydropower station gate to solve the problem that during the operation of the gate, the water flow impact causes the gate to vibrate, resulting in the gate cracking.

The dam is arranged between the walls, the water gate is arranged between the walls, the torsion column is connected to the wall, the cylinder is connected to the torsion column, and the cylinder is connected to the water gate. The torsion column and the cylinder cooperate to drive the water gate to rotate;

[0008] A buffer component, which is connected to the dam. When the water level difference between the inside and outside of the water gate is large, the buffer component reduces the water level difference between the inside and outside of the water gate;

[0009] The shock-absorbing component is connected to the water gate. When there is a large difference in water level inside and outside the water gate, the shock-absorbing component weakens the pressure of the water flow on the water gate.

[0010] Among them, the induction component includes two sliding grooves. The two sliding grooves are opened on the wall, and the two sliding grooves are respectively arranged at the inner and outer ends of the water gate.

The rotation of the rotating plate drives the support plate to move vertically, and the rotating shaft and the support rod cooperate to support the support plate.

[0013] Among them, a rotating wheel is connected to the support plate. When the rotating plate rotates, the rotating wheel rotates around the rotating plate.

[0014] Among them, the moving piece includes a moving groove.

Specific implementation mode

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a locking device for a water turbine gate, including: wall 1, dam 2, water gate 3, torsion column 5 and cylinder 6. The dam 2 is arranged between the walls 1, the water gate 3 is arranged between the walls 1, the torsion column 5 is rotatably connected to the wall 1, the cylinder 6 is fixedly connected to the torsion column 5, and the cylinder 6 is connected to the water gate 3. The torsion column 5 and the cylinder 6 cooperate to drive the water gate 3 to rotate. When water needs to be released, the torsion column 5 drives the cylinder 6 to rotate, and the cylinder 6 expands and contracts. The torsion column 5 and the cylinder 6 cooperate to drive the water gate 3 to rotate, thereby opening and closing the water gate 3 to store and release water;

[0033] It also includes:

[0034] Induction component 4, which is connected to the wall 1. The induction component 4 senses and monitors the water levels inside and outside the water gate 3, senses the water level difference inside and outside the water gate 3, and can effectively control the water flow for releasing water according to the water level difference, and observe the water level in real time to prevent backflow when the water level is too high;

[0035] Buffer component 7, which is connected to the dam 2. When the water level difference inside and outside the water gate 3 is large and water is released, the buffer component 7 reduces the water level difference inside and outside the water gate, and thus the buffer component 7 can slow down the impact of water release on the water gate 3;

[0036] The shock-absorbing component 10 is connected to the water gate 3. When the water level difference inside and outside the water gate 3 is large, the shock-absorbing component 10 weakens the pressure of the water flow on the water gate 3, thereby preventing the large water flow impact from damaging the water gate 3.

[0037] The sensing component 4 includes two sliding grooves 42. The two sliding grooves 42 are opened on the wall 1 and are respectively arranged at the inner and outer ends of the water gate 3. A water level sensor 41 and a water level sensor 43 are connected to the two sliding grooves 42. The water level sensor 41 and the water level sensor 43 monitor the water levels on both sides of the water gate 3. The water level sensor 41 can sense the water-accumulating end of the water gate 3, and the water level sensor 43 can sense the water-discharging end of the water gate 3. The water level sensor 41 and the water level sensor 43 can move vertically on the sliding groove 42 according to the water volume. Thus, according to the positions of the water level sensor 41 and the water level sensor 43, the water level difference on both sides of the water gate 3 can be known in time, and then the water gate 3 can be started to drain water, preventing the water level difference at both ends from being too large and squeezing the water gate 3, thereby preventing the water gate 3 from cracking.

[0038] The buffer component 7 includes a driving cavity 75 and a buffer plate 71. The driving cavity 75 is arranged on the wall 1, and the buffer plate 71 is connected to the dam 2. A motor 11 is connected in the driving cavity 75. The motor 11 drives the torsion column 5 to rotate. A rotating plate 72 is connected to the output shaft of the motor 11. A connecting piece 73 is connected to the rotating plate 72, and a moving piece 74 is connected to the connecting piece 73. The buffer plate 71 is driven to move vertically by the moving piece 74. The connecting piece 73 and the moving piece 74 are arranged in the driving cavity 75. The driving cavity 75 can protect the connecting piece 73, preventing the connecting piece 73 and the moving piece 74 from contacting water and extending the service life of the connecting piece 73 and the moving piece 74. When the water level difference inside and outside the water gate 3 is large, the motor 11 drives the connecting piece 73 to work, and then drives the moving piece 74. The moving piece 74 can drive the buffer plate 71 to move vertically. Thus, when the buffer plate 71 moves upward, the water level difference inside and outside the water gate 3 can be reduced.

[0039] The connecting piece 73 includes a support plate 731. The support plate 731 is arranged on the rotating plate 72. A support rod 733 is fixedly connected to the support plate 731. A rotating shaft 732 is rotatably connected to the support rod 733, and the rotating shaft 732 is connected in the driving cavity 75. The rotation of the rotating plate 72 drives the support plate 731 to move vertically. The rotating shaft 732 and the support rod 733 cooperate to support the support plate 731. The motor 11 drives the rotating plate 72 to rotate. Thus, the support plate 731 can move according to the shape of the rotating plate 72, and then the support plate 731 can move vertically. The support rod 733 rotates on the rotating shaft 732. Thus, the rotating shaft 732 and the support rod 733 can be used in cooperation to support and fix the support plate 731, and then drive the moving piece 74 to move, facilitating driving the moving piece 74 to move vertically.

[0040] A rotating wheel 734 is rotatably connected to the support plate 731. When the rotating plate 72 rotates, the rotating wheel 734 rotates around the rotating plate 72. Thus, the rotating wheel 734 can move the support plate 731 on the rotating plate 72, thereby ensuring the vertical movement of the support plate 731.

[0041] The moving member 74 includes a moving groove 741 provided on the wall 1. A moving rod 742 is connected to the support plate 731, and the moving rod 742 is slidably connected to the moving groove 741. One end of the moving rod 742 extends out of the moving groove 741 and is connected to a lifting rod 743. A groove 744 is formed on the dam 2, and the lifting rod 743 is slidably connected to the groove 744. When the water levels at both ends of the water gate 3 differ greatly, while the water gate 3 is being opened, the motor 11 drives the rotating plate 72 to rotate. The rotating plate 72 drives the support plate 731 to move vertically. The vertical movement of the support plate 731 can drive the moving rod 742 to move vertically, and thus the lifting rod 743 can move up and down in the groove 744, causing the buffer plate 71 to move vertically, thereby reducing the water level difference between the two sides of the water gate 3, reducing the impact force of the water flow on the water gate 3, protecting the water gate 3, and preventing the water gate 3 from cracking.

[0042] Embodiment 2

[0043] The damping assembly 10 includes an energy absorption member 8 and a damping member 9. The energy absorption member 8 is connected to the water gate 3, and the damping member 9 is connected to the cylinder 6. The energy absorption member 8 and the damping member 9 are used in cooperation to reduce the vibration of the water gate 3. By using the energy absorption member 8 in cooperation, the impact force of the water on the water gate 3 can be converted into heat energy, and the damping member 9 can reduce the vibration of the water gate 3.

[0044] The energy absorption member 8 includes a support frame 81. The support rod is arranged between the cylinder 6 and the water gate 3. A pin slot 82 is provided on the support member, and a pin post 83 is connected to the water gate 3. The pin post 83 is engaged with the pin slot 82. When discharging water with a large water level difference, the water flow impacts the energy absorber 12 on the water gate 3 to generate kinetic energy, causing the pin post 83 to engage with the pin slot 82. Thus, the impact force of the water flow on the water valve can be converted into heat energy, and the impact force of the water flow on the water gate 3 can be reduced.

[0045] The damping member 9 includes a damping plate 96. The damping plate 96 is connected to the cylinder 6. A placement groove 95 is formed in the damping plate 96. A damping column 92 is arranged in the placement groove 95, and the damping column 92 is slidably connected to the placement groove 95. A first fixing plate 91 is connected to the damping column 92. A second fixing plate 94 is connected in the placement groove 95. A spring 93 is arranged between the first fixing plate 91 and the second fixing plate 94. When draining water with a large water level difference, the elastic force of the spring 93 will buffer the damping column 92, thereby reducing the vibration of the water gate 3. When the water level difference is small, the vibration force of the water valve decreases, and it cannot move the damping column 92 to one end in the damping groove. Thus, the repeated use of the damping column 92 and the spring 93 can be prevented, protecting the damping column 92 and the spring 93 and extending their service life.

[0046] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
