Description

Technical Field

[0001] This utility model relates to the field of hydropower equipment technology, specifically a decontamination device for a hydropower turbine. Background Technology

[0002] Hydropower generation utilizes the potential energy of water flowing from high places like rivers and lakes to low places, converting the potential energy into the kinetic energy of a turbine. The turbine then powers a generator to produce electricity. The water power drives the turbine, converting water energy into mechanical energy. If another machine (generator) is connected to the turbine, it generates electricity as the turbine rotates, thus converting mechanical energy back into electrical energy. In a sense, hydropower generation is the process of converting the potential energy of water into mechanical energy, and then into electrical energy.

[0003] After prolonged operation, existing water turbines accumulate dirt carried by the water flow. This long-term accumulation increases the weight of the turbine, increases the resistance to its rotation, and consequently reduces its power generation efficiency. Currently, cleaning and decontamination of water turbines is still done manually, which is time-consuming and labor-intensive. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A decontamination device for a hydroelectric turbine includes: a turbine body and a cleaning assembly; the cleaning assembly is disposed on the turbine body; the cleaning assembly includes a lifting rod mounted on the turbine body, a mounting frame fixed to the drive end of the lifting rod, a cleaning mechanism disposed on the mounting frame, a baffle detachably inserted into the cleaning mechanism and located on the turbine body, and an adjustment mechanism disposed on the cleaning mechanism; the cleaning mechanism includes a motor mounted on the mounting frame, a rotating shaft fixed to the drive end of the motor, and a cleaning brush disposed on the rotating shaft.

[0007] In a preferred embodiment, the present invention can be further configured such that the adjusting mechanism includes a telescopic rod mounted on the mounting frame, an adjusting ring fixed to the end of the telescopic rod and fitted on the rotating shaft, and a corrugated telescopic sleeve connected to the bottom of the telescopic rod and fitted on the rotating shaft for the distribution of the cleaning brush.

[0008] In a preferred embodiment, the present invention can be further configured such that: guide rods connected to the turbine body and the regulating ring are respectively inserted into the mounting frame.

[0009] In a preferred embodiment, the present invention can be further configured such that: a cleaning port for placing the baffle is provided on the turbine body, and a sealing ring is provided at the bottom of the baffle on the side of the cleaning port.

[0010] In a preferred embodiment, the present invention can be further configured such that: a locking block is fixed to the end of the rotating shaft, and a slot for inserting the locking block is provided on the baffle.

[0011] In a preferred embodiment, the present invention can be further configured such that the rotating shaft is a rubber rod structure.

[0012] In a preferred embodiment, the present invention can be further configured such that a storage groove located below the baffle is provided inside the turbine body.

[0013] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] 1. This utility model uses a cleaning component that can drive the mounting frame to rise and fall using a lifting rod. This allows the cleaning brush to be moved down between the water turbines when cleaning the water turbine body. Then, the motor drives the cleaning brush to clean both sides of the slowly adjusting impeller. After one cleaning cycle, the cleaning brush can be lifted up. This process can be repeated. This solution eliminates the need for manual cleaning, has a good cleaning effect, and is easy to promote and use.

[0015] 2. This utility model, through its cleaning component, utilizes a rubber-structured rotating shaft. By cooperating with the rotating shaft to drive the rotating shaft to rotate appropriately, the locking block is disengaged from the slot. When continuously cleaning the water wheel, there is no need to raise the cleaning brush. Under the pressure of the water wheel, the rotating shaft will deform. After the cleaned water wheel rotates away, it resets and repeats the cleaning process. This provides two operating methods for the solution, which is quite reasonable.

[0016] 3. This utility model, through the cleaning component, allows the adjustment ring on the rotating shaft to be adjusted by the telescopic rod, thereby compressing the corrugated telescopic sleeve. This results in different densities of the cleaning brushes required for cleaning. When there is a lot of dirt, pressing down the corrugated telescopic sleeve compresses the cleaning brushes together, making them more robust and improving the cleaning effect. This allows for the adjustment of the cleaning force. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of a water turbine cleaning device for hydroelectric power generation.

[0025] Combination Figure 1-3 As shown, the present invention provides a water turbine cleaning device for hydropower generation, comprising: a turbine body 100 and a cleaning component 200; the cleaning component 200 is disposed on the turbine body 100.

[0026] The cleaning assembly 200 includes a lifting rod 210 mounted on the turbine body 100, a mounting frame 220 fixed to the drive end of the lifting rod 210, a cleaning mechanism mounted on the mounting frame 220, a baffle 230 detachably inserted into the cleaning mechanism and located on the turbine body 100, and an adjustment mechanism mounted on the cleaning mechanism. The cleaning mechanism includes a motor 240 mounted on the mounting frame 220, a rotating shaft 250 fixed to the drive end of the motor 240, and a cleaning brush 260 mounted on the rotating shaft 250. Through the cleaning assembly 200, the lifting rod 210 can drive the mounting frame 220 to rise and fall, thereby moving the cleaning brush 260 between the impellers when cleaning the impellers inside the turbine body 100. Then, the motor 240 drives the cleaning brush 260 to clean both sides of the slowly adjusting impeller. After one cleaning is completed, the cleaning brush 260 can be lifted. This process can be repeated. This solution does not require manual cleaning, has a good cleaning effect, and is easy to promote and use.

[0027] Specifically, the adjustment mechanism includes a telescopic rod 270 mounted on the mounting bracket 220, an adjustment ring 280 fixed to the end of the telescopic rod 270 and fitted on the rotating shaft 250, and a corrugated telescopic sleeve 290 connected to the bottom of the telescopic rod 270 and fitted on the rotating shaft 250 for distributing the cleaning brushes 260. The position of the adjustment ring 280 on the rotating shaft 250 can be adjusted by using the telescopic rod 270, thereby compressing the corrugated telescopic sleeve 290, so that the density of the cleaning brushes 260 required for cleaning is different. When there is a lot of dirt, pressing down the corrugated telescopic sleeve 290 compresses the cleaning brushes 260 together, making them more robust and improving the cleaning effect, thus realizing the adjustment of the cleaning force.

[0028] Furthermore, guide rods 221 connected to the turbine body 100 and the adjusting ring 280 are respectively inserted into the mounting frame 220. The guide rods 221 can improve the stability of the mounting frame 220 and the adjusting ring 280 during displacement, ensuring stable operation.

[0029] On the other hand, the turbine body 100 is provided with a cleaning port 110 for placing the baffle 230, and the bottom of the baffle 230 is provided with a sealing ring 231 located on the side of the cleaning port 110. The sealing ring 231 can seal the cleaning port 110. When cleaning is not being carried out, the baffle 230 does not affect the normal operation of the turbine body 100, which is quite reasonable.

[0030] It should be noted that a locking block 251 is fixed to the end of the rotating shaft 250, and a slot 232 for the locking block 251 to be inserted is provided on the baffle 230. The rotating shaft 250 is a rubber rod structure, the locking block 251 is a strip structure, and the slot 232 is a common structure with a strip-shaped opening and a disc-shaped inner cavity. After the locking block 251 is rotated, it can be pulled out of the slot 232. Conversely, the locking block 251 can be inserted into the slot 232 and then rotated to lock it. That is, the rotating shaft 250 can lift the baffle 230. This makes it convenient for the rotating shaft 250 to be unaffected by the baffle 230 when it is deformed by pressure. When cleaning with the other method of multiple lifting and lowering cleaning brush 260, it is not necessary to disengage the baffle 230, which is more practical.

[0031] Furthermore, the turbine body 100 is provided with a storage groove 120 located below the baffle 230. The storage groove 120 can hold the detached baffle 230, which is quite practical.

[0032] The working principle and usage process of this utility model are as follows: When cleaning the turbine body 100 is required, the machine is first stopped appropriately. Then, the lifting rod 210 drives the mounting frame 220 to rise and fall, thereby moving the cleaning brush 260 between the water wheels inside the turbine body 100. Then, the motor 240 drives the cleaning brush 260 to clean both sides of the slowly adjusting impeller. After one cleaning is completed, the cleaning brush 260 can be lifted. This process is repeated. Water is then introduced into the turbine body 100 as appropriate, or the water wheel is rotated appropriately using a relevant motor. This cleaning process is repeated. When it is necessary to adjust the cleaning force, the position of the adjusting ring 280 on the rotating shaft 250 is adjusted using the telescopic rod 270, thereby compressing the corrugated telescopic sleeve 290. This results in different densities of the cleaning brush 260 required for cleaning. When there is a lot of dirt, the corrugated telescopic sleeve 290 is pressed down to compress the cleaning brush 260 together, making it more durable, thus achieving the adjustment of the force.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
