Description

Technical Field

[0001] This invention relates to the field of hydropower technology, and more specifically to a hydropower turbine protection device. Background Technology

[0002] The basic principle of hydropower is to use the difference in water level to generate electricity in conjunction with a turbine generator. That is, the potential energy of water is converted into the mechanical energy of the turbine, and then the mechanical energy drives the generator to obtain electricity. Scientists have used this natural condition of water level difference to effectively utilize fluid dynamics engineering and mechanical physics to achieve the highest power generation, providing people with cheap and pollution-free electricity.

[0003] Hydropower generation utilizes the potential energy of water level to impact an impeller and generate electricity. However, some problems still exist in the operation of hydropower impellers: the water flowing from a height generates a large impact force, and if floating debris such as driftwood, aquatic plants, and leaves are mixed in with the water, it may directly damage the impeller. However, filtering the water flow with a filter will cause a loss of the water's potential energy, reducing the efficiency of hydropower generation. At the same time, some microorganisms in the water will adhere to the surface of the impeller, increasing the burden on the impeller's rotation and thus reducing the impeller's power generation efficiency. During hydropower generation, different water flow rates result in different efficiencies. When the water flow rate is too large and the water velocity is too fast, it is easy to damage the hydropower impeller. In order to avoid impeller damage, the water flow speed needs to be properly controlled. However, existing hydropower impeller protection devices cannot control the water flow speed and cannot protect the impeller, making them impractical. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the present invention aims to provide a hydroelectric turbine protection device, which protects the hydroelectric turbine by setting a diversion protection mechanism, cleans the water surface by setting a cleaning mechanism, and replaces and cleans the turbine by setting a turbine mechanism, thereby preventing aquatic organisms from adhering to the turbine surface, increasing the burden on turbine rotation, and reducing power generation efficiency.

[0005] To achieve the above objectives, the present invention provides a hydroelectric turbine protection device, comprising a diversion protection mechanism, a cleaning mechanism, an impeller mechanism, a diversion motor, and a cleaning motor. The diversion protection mechanism includes a diverter, wherein a power generation channel and a diversion channel are symmetrically arranged inside the diverter, and a channel partition is fixedly installed between the power generation channel and the diversion channel. An outlet and an inlet are fixedly installed at both ends of the diverter, respectively. A diversion rotating shaft is rotatably connected to the end of the channel partition away from the outlet. The output end of the diversion motor is fixedly connected to the diversion rotating shaft, and a diversion control plate is fixedly installed on the outer side of the diversion rotating shaft.

[0006] The aforementioned hydroelectric turbine protection device includes a cleaning mechanism comprising a cleaning drive gear, a cleaning transmission belt meshing with the outer side of the cleaning drive gear, cleaning driven gears symmetrically meshing with both ends of the cleaning transmission belt, a plurality of belt rotating rods fixedly installed on the outer side of the cleaning transmission belt, and a cleaning hook fixedly installed at the end of the belt rotating rod away from the cleaning transmission belt.

[0007] The aforementioned hydroelectric turbine protection device includes a cleaning motor whose output end is fixedly connected to a cleaning drive gear, and the cleaning motor is fixedly installed on the outside of the power generation channel.

[0008] The aforementioned hydroelectric turbine protection device includes a turbine mechanism comprising a turbine rotating shaft, a plurality of turbine sliding grooves being formed on the outer side of the turbine rotating shaft, and a rotating turbine being slidably connected to the surface of the turbine sliding grooves.

[0009] The aforementioned hydroelectric turbine protection device comprises at least six rotating impellers, and the impeller shafts are fixedly installed inside the distributor.

[0010] The aforementioned hydroelectric turbine protection device includes a waste collection bin on one side of the cleaning transmission belt, which is fixedly installed on the top of the power generation channel.

[0011] The aforementioned hydroelectric turbine protection device includes a shunt motor fixedly installed on the top of a channel partition, with the inlet and outlet connected via a power generation channel and a shunt channel. Beneficial effects

[0012] 1. This invention protects the impeller of a hydroelectric generator by setting up a diversion protection mechanism. The diversion control board is controlled by a diversion motor to divert the water flow. When the water flow velocity is too fast, in order to avoid the water flow directly impacting the rotating impeller and causing damage to the rotating impeller, the diversion channel is opened to slow down the water flow velocity and protect the rotating impeller.

[0013] 2. This invention cleans the water surface by setting up a cleaning mechanism. The cleaning motor drives the cleaning transmission belt to rotate, so that the cleaning hook can clean up the leaves, aquatic plants and floating wood on the water surface in a timely manner, avoiding damage to the rotating impeller caused by the leaves, aquatic plants and floating wood.

[0014] 3. This invention uses an impeller mechanism to replace and clean the impeller, preventing aquatic organisms from adhering to the impeller surface, increasing the burden on the impeller rotation, and reducing power generation efficiency. At the same time, when cleaning and replacing the impeller, the rotating impellers can be disassembled one by one from the impeller sliding groove, which is convenient and quick, improves the replacement and maintenance rate, and thus improves the efficiency of hydropower generation.

A channel partition 109 is fixedly installed between the power generation channel 102 and the diversion channel 103. An outlet 104 and an inlet 105 are fixedly installed at both ends of the diverter 101, respectively. A diversion rotating shaft 108 is rotatably connected to the end of the channel partition 109 away from the outlet 104. The output end of the diversion motor 106 is fixedly connected to the diversion rotating shaft 108. A diversion control plate 107 is fixedly installed on the outside of the diversion rotating shaft 108. The diversion motor 106 is fixedly installed on the top of the channel partition 109. The inlet 105 and outlet 104 are connected through the power generation channel 102 and the diversion channel 103. The rotating impeller 303 of the hydroelectric generator is protected by a diversion protection mechanism 1. The diversion motor 106 controls the diversion control plate 107 to control the water flow. When the water flow velocity is too fast, in order to avoid the water flow directly impacting the rotating impeller 303 and causing damage to the rotating impeller 303, the diversion channel 103 is opened to slow down the water flow velocity and protect the rotating impeller 303.

[0018] The cleaning mechanism 2 includes a cleaning drive gear 201, a cleaning transmission belt 203 meshing with the outer side of the cleaning drive gear 201, and cleaning driven gears 202 symmetrically meshing with both ends of the cleaning transmission belt 203.

By setting up the cleaning mechanism 2, the water surface is cleaned. The cleaning motor 206 drives the cleaning transmission belt 203 to rotate, so that the cleaning hook 205 can clean the leaves, aquatic plants and floating wood on the water surface in a timely manner, avoiding damage to the rotating impeller 303 caused by the leaves, aquatic plants and floating wood.

[0019] The impeller mechanism 3 includes an impeller rotating shaft 301. Several impeller sliding grooves 302 are provided on the outer side of the impeller rotating shaft 301.
