Description

Technical Field

[0001] The present invention relates to the field of hydropower station equipment, and specifically to an emergency switch device for valves used in hydropower stations. Background Art

[0002] Valves are important components indispensable for ensuring the smooth operation of hydropower stations. They control the operation of each pipeline in the hydropower station. During the normal operation of the hydropower station, valves can control the flow rate of water and the pressure generated by the water on the overall structure of the hydropower station during the flowing process, and at the same time can prevent water from flowing back in the pipeline. They are key components indispensable in the operation of hydropower stations;

[0003] Between the connected and closed states between the valve and the pipeline, according to the water hammer effect, water will generate pressure on the pipelines and valves of the hydropower station, which is extremely likely to cause wear and damage to the valves and pipelines in the hydropower station, resulting in failures of the hydropower station and huge economic losses. When the valve in the hydropower station regulates the connected and closed states of the pipeline, when the valve fails, it is extremely likely to cause problems associated with the change of the pipeline state, thereby causing the power generation of the hydropower station to be interrupted. Summary of the Invention

[0004] The purpose of the present invention is to provide an emergency switch device for valves used in hydropower stations, which can improve the molding speed of injection-molded products in the injection molding process.

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0006] An emergency switch device for valves used in hydropower stations includes a housing. One end of an inlet pipe and one end of an outlet pipe are coaxially connected to two ends of the housing respectively. A carrier pipe with both ends docked with the inlet pipe and the outlet pipe respectively is arranged at the center of the housing. The other end of the outlet pipe is connected to a water valve housing. A first connection port and a second connection port are symmetrically arranged on the outer side of the water valve housing. A spherical water valve is movably connected inside the water valve housing;

[0007] Two symmetrically arranged transfer grooves are arranged on the outer side surface of the carrier pipe. One end of a number of telescopic pistons is connected inside the transfer grooves. The telescopic pistons are arranged in a circular array around the axis of the carrier pipe. A number of carrier through holes are arranged on the inner side surface of the carrier pipe. Each carrier through hole corresponds to a telescopic piston. The other end of the telescopic piston controls the distance from the carrier through hole through telescopic control;

[0008] A connecting piece is arranged inside the housing. The connecting piece is sleeved on the outer side surface of the carrier pipe. One end of the connecting piece is docked with one transfer groove respectively. The water inside the transfer groove is guided through the connecting piece. The connecting piece provides electrical energy for a storage battery through the flow of water inside the connecting piece.

[0009] Optionally, a connecting member is arranged inside the housing. The connecting member includes two connecting disks, a blade runner, and a transmission ratchet. Both of the two connecting disks are sleeved on the outer side of the bearing pipe. A number of evenly distributed blade holes are arranged on the surfaces of both connecting disks. A blade runner is arranged between the two connecting disks. Both ends of the blade runner are respectively embedded in the blade holes in the two connecting disks. A transmission ratchet is coaxially sleeved at the middle position of the blade runner. The blade rotation directions on both sides of the transmission ratchet of the blade runner are opposite. One end of the blade runner passes through the housing and is externally connected to a storage battery. The blade runner drives itself and the transmission ratchet to rotate along with the flow of water in the blade holes.

[0010] Optionally, a transmission ratchet is arranged between the blade holes corresponding to both ends of each blade runner. The transmission ratchet is sleeved on the outer side of the blade runner. The blade runner controls the synchronous transmission of the transmission ratchet through rotation; a composite disk is arranged on the outer sides of the two connecting disks. The inner side surface of the composite disk is connected to the outer side surfaces of the two connecting disks. One-way teeth meshing with the outer shape of the one-way teeth of the transmission ratchet are arranged on the inner side surface of the composite disk. The rotation of the transmission ratchet will control the rotation of the composite disk accordingly.

[0011] Optionally, a number of protrusions are arranged on the outer side surface of the composite disk. A number of swing rods are arranged on the inner side surface of the housing. The swing rods are arranged in a circular array around the axis of the housing. One end of the swing rod is hinged to the inner side surface of the housing. The other end of the swing rod is movably connected to the outer side surface of the composite disk. The end of the swing rod hinged to the inner side surface of the housing passes through the housing and is connected to a storage battery. The composite disk drives the protrusions to rotate through rotation. The protrusions contact the swing rods outside the composite disk through rotation, thereby pushing the swing of the swing rods.

[0012] Optionally, a number of turbine water inlets communicating the inner side surface and the outer side surface of the composite disk are arranged at the composite disk. The turbine water inlets are arranged in a circular array around the axis of the composite disk.

[0013] Optionally, the outer shape of the turbine water inlet is arc-shaped. When the water in the composite disk overflows through the turbine water inlet, the composite disk is guided to generate relative rotation through contact with the turbine water inlet.

[0014] Optionally, drain ports are arranged at both ends of the housing. The drain ports are symmetrically arranged.

[0015] Optionally, the outer shape of the drain port is arc-shaped.

[0016] Optionally, a drain cover is hinged on the side of the drain port away from the housing. The drain cover can be pushed by the water on the side close to the drain port to swing. The drain cover is limited by the drain port, and the swing area of the drain cover is limited outside the drain port.

[0017] Optionally, the outer shape of the drainage cover is an arc shape consistent with the drainage opening.

[0018] Beneficial effects: 1. The blade runner of the present invention can utilize the additional pressure generated by the water hammer effect, convert the pressure into additional electrical energy, and collect the electrical energy. When the valve has problems, it can provide additional emergency power.

[0019] 2. The composite disk of the present invention rotates under the rotation of the transmission ratchet. At the same time, when water flows out of the blade wheel, it will finally flow to the drainage opening through the turbine water inlet on the side of the composite disk. During the process of water flowing out, a force that assists the rotation of the composite disk is generated synchronously, and then this part of the force can be used to drive the swing of the swing rod, thereby generating electricity.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] As Figures 1 - 4As shown, a valve emergency switch device for a hydropower station mainly includes a shell 1, both ends of the shell 1 are provided with drain ports 54, the drain ports 54 are symmetrically arranged, and a drain cover 55 is hingedly connected to the drain port 54 on the side away from the shell 1, and one end of a water inlet pipe 11 and one end of a water outlet pipe 12 are coaxially connected at both ends of the shell 1, and a bearing pipe 3 whose two ends are respectively connected to the water inlet pipe 11 and the water outlet pipe 12 is provided at the center of the shell 1. Water flows to the bearing pipe 3 through the water inlet pipe 11, and then flows from the bearing pipe 3 to the water outlet pipe 12 until it reaches the water valve shell 2. The other end of the water outlet pipe 12 is connected to the water valve shell 2, and the outer side of the water valve shell 2 is symmetrically provided with a first docking port 22 and a second docking port 23. Two pairs of interfaces 23, the first pair of interfaces 22 is connected to the water outlet pipe 12, and the second pair of interfaces 23 is communicated with the outside. The ball water valve 21 is movably connected inside the water valve housing 2. The ball water valve 21 is provided with a water valve through hole 211 that coincides with the axis of the first pair of interfaces 22 and the axis of the second pair of interfaces 23. The outer side of the ball water valve 21 passes through the water valve housing 2 and is connected with a water valve runner 24. The axis of the water valve runner 24 is arranged perpendicular to the axis of the ball water valve 21. The water valve runner 24 controls the coincidence and stagger between the axis of the ball water valve 21 and the axis of the first pair of interfaces 22 and the axis of the second pair of interfaces 23 by rotating, thereby controlling the flow of water in the water outlet pipe 12;

[0028] Two symmetrically arranged transfer grooves 31 are provided on the outer side of the supporting tube 3, and one end of a plurality of telescopic pistons 32 is connected to the transfer groove 31. The telescopic pistons 32 are arranged in a circular array around the axis of the supporting tube 3. A plurality of bearing through holes 33 are provided on the inner side of the supporting tube 3, and each bearing through hole 33 corresponds to the telescopic piston 32. The other end of the telescopic piston 32 is controlled by telescopic movement to adjust the distance from the bearing through hole 33. After the spherical water valve 21 rotates, when the water in the water outlet pipe 12 switches between the flowing and blocked states, a certain pressure will be generated on the water inlet pipe 11, the supporting tube 3, the water outlet pipe 12 and the spherical water valve 21. At this time, the pressure will be transmitted to the telescopic piston 32, generating a force that makes the telescopic piston 32 move away from the axis of the supporting tube 3, thereby allowing the water to flow to the transfer groove 31 and even the structure connected thereto, thereby consuming the pressure released by accidental touch in the water, and reducing the damage to the water inlet pipe 11, the supporting tube 3, the water outlet pipe 12 and the spherical water valve 21.

[0029] A connecting member 4 is arranged inside the housing 1. The connecting member 4 includes two connecting disks 41, a blade runner 43 and a transmission ratchet 44. Both of the two connecting disks 41 are sleeved on the outer side surface of the bearing pipe 3. A number of uniformly distributed blade holes 42 are arranged on the surfaces of both connecting disks 41. A blade runner 43 is arranged between the two connecting disks 41. The two ends of the blade runner 43 are respectively embedded in the blade holes 42 in the two connecting disks 41. A transmission ratchet 44 is coaxially sleeved at the middle position of the blade runner 43. The blade rotations on both sides of the transmission ratchet 44 of the blade runner 43 are opposite. One end of the blade runner 43 passes through the housing 1 and is externally connected to a storage battery;

[0030] The spherical water valve 21 controls the connection and disconnection of the water outlet pipe 12 through rotation. When the water outlet pipe 12 switches between connection and disconnection, it will control the contraction of the telescopic piston 32, thereby controlling the water to enter the transfer tank 31. The water contacts the connecting disk 41 at the transfer tank 31 and flows through the blade holes 42 on the surface of the connecting disk 41. During the flow through the blade holes 42, it pushes the blade runner 43 to rotate. Therefore, the rotating blade runner 43 can charge the externally connected storage battery;

[0031] A transmission ratchet 44 is arranged between the blade holes 42 corresponding to the two ends of each blade runner 43. The transmission ratchet 44 is sleeved on the outside of the blade runner 43. The blade runner 43 controls the synchronous transmission of the transmission ratchet 44 through rotation. A composite disk 5 is arranged on the outer sides of the two connecting disks 41. The inner side surface of the composite disk 5 is connected to the outer side surfaces of the two connecting disks 41. One-way teeth meshing with the outer shape of the one-way teeth of the transmission ratchet 44 are arranged on the inner side surface of the composite disk 5. The rotation of the transmission ratchet 44 will control the rotation of the composite disk 5 accordingly;

[0032] The water flows from both ends of the blade runner 43 towards the transmission ratchet 44 respectively, and the flow directions of the water are opposite. The rotations on both ends of the blade runner 43 are opposite, thereby realizing the rotation of the blade runner 43 driving the transmission ratchet 44 to rotate. The transmission ratchet 44 meshes with the one-way teeth on the inner side of the composite disk 5, and the transmission ratchet 44 drives the composite disk 5 to rotate in the same direction.

[0033] As Figure 5 shown, a number of protrusions 51 are arranged on the outer side surface of the composite disk 5, and a number of swing rods 52 are arranged on the inner side surface of the housing 1. The swing rods 52 are arranged in a circular array around the axis of the housing 1. One end of the swing rod 52 is hinged to the inner side surface of the housing 1, and the other end of the swing rod 52 is movably connected to the outer side surface of the composite disk 5. The end of the swing rod 52 hinged to the inner side surface of the housing 1 passes through the housing 1 and is connected to a storage battery. The composite disk 5 drives the protrusions 51 to rotate through rotation. The protrusions 51 contact the swing rods 52 outside the composite disk 5 through rotation, thereby pushing the swing of the swing rods 52;

[0034] The composite disk 5 is provided with a plurality of turbine water inlets 53 connecting the inner side and the outer side of the composite disk 5. The turbine water inlets 53 are arranged in a circular array around the axis of the composite disk 5. The outer shape of the turbine water inlets 53 is an arc shape. When the water in the composite disk 5 overflows through the turbine water inlets 53, it contacts the turbine water inlets 53, thereby guiding the composite disk 5 to generate relative rotation.

[0035] The composite disk 5 rotates under the rotation of the transmission ratchet 44. At the same time, when water flows out of the blade wheel, it will finally flow to the drain port 54 through the turbine water inlet 53 on the side of the composite disk 5. The drain port 54 is hinged with a drain cover 55 on the side away from the outer shell 1. The water flows through the drain cover 55 to the outside. When the drain cover 55 is pushed by the water outside the device, the drain cover 55 will not swing toward the direction inside the drain port 54. In the process of water flowing out, a force is simultaneously generated to assist the rotation of the composite disk 5, and this part of the force can be used to drive the swing rod 52 to swing, thereby generating electricity.

[0036] First, the water valve wheel 24 is rotated to drive the spherical water valve 21 to rotate. The water in the water outlet pipe 12 flows or is blocked as the axis of the water valve through hole 211 coincides with or staggers with the axis of the water outlet pipe 12. The change in the state of the water will generate pressure on the water inlet pipe 11, the supporting pipe 3, the water outlet pipe 12 and the spherical water valve 21. At this time, the telescopic piston 32 is affected by the pressure and shrinks in a direction away from the axis of the supporting pipe 3 until the supporting pipe 3 and the transfer tank 31 begin to communicate, and water enters the transfer tank 31. When the water fills the transfer tank 31, it will flow to the blade hole 42 and until it passes through the blade hole 42. In the process of passing through the blade hole 42, the flow of water will drive the blade wheel 43 to rotate with its own rotation direction. At this time, the blade wheel 43 can provide power for the external battery.

[0037] When the blade wheel 43 rotates, it will drive the transmission ratchet 44 to rotate, and multiple transmission ratchets 44 will rotate together, and then the composite disk 5 that matches and meshes with all the transmission ratchets 44 will rotate accordingly. When the composite disk 5 rotates, the protrusion 51 on its outer side will push the swing rod 52 to swing, thereby providing electrical energy for the battery connected to the swing rod 52. At the same time, the water flowing out of the connecting disk 41 will flow downward until it contacts the turbine guide hole on the surface of the composite disk 5. Under the action of gravity, the water applies force to the turbine guide hole from top to bottom, thereby providing auxiliary effect for the rotation of the composite disk 5, and can further drive the swing of the swing rod 52 to provide more electrical energy for the battery. After that, excess water can flow out through the drain port 54, and the drain cover 55 can prevent external substances from flowing into the device.
