Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic generators, in particular to a hydraulic generator with an anti-winding function. Background Art

[0002] A hydroelectric generator is a generator that converts water energy into electrical energy. Its principle is to use the impact force of the water flow to drive the turbine or waterwheel blades to rotate, thereby converting water energy into mechanical energy. The turbine shaft in turn drives the rotor of the generator, converting mechanical energy into electrical energy for output. It is the main power equipment for producing electricity in hydropower stations.

[0003] During the operation of a hydroelectric generator, the impact force of the water flow drives the turbine to rotate and generate electricity. However, since hydroelectric generators are generally used outdoors, there may be debris such as sinks and filamentous garbage in the water, which can easily cause the turbine to be entangled with water plants, affecting the rotation of the turbine and increasing the workload for manual cleaning operations. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a hydroelectric generator with an anti-winding function, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a hydroelectric generator with anti-winding function, including a generator rotor, a support, an outer shell and turbine blades, the top of the turbine blades is connected to a rotating shaft, the outside of the rotating shaft is connected to a connecting rod, and the outside of the connecting rod is sleeved with an interception sleeve.

[0006] Optionally, the turbine blades are fixedly connected to the rotating shaft, and the rotation of the turbine blades can drive the rotation of the rotating shaft, so that the rotating shaft drives the generator rotor to rotate, thereby achieving the effect of power generation.

[0007] Optionally, the connecting rods are staggeredly distributed on the outside of the rotating shaft, which will not affect the flow rate of the water flow, and the outside of the connecting rods is provided with threads, and there are multiple connecting rods.

[0008] Optionally, the interception sleeve is provided with a thread corresponding to the connecting rod, and the interception sleeve is movably sleeved on the outside of the connecting rod, so as to realize the movable sleeve connection of the interception sleeve on the outside of the connecting rod, facilitate the disassembly and assembly of the interception sleeve, and provide convenience for the later cleaning of the interception sleeve. The outer end of the interception sleeve is connected with a flat plate, and the flat plate has a flat structure, which is convenient for people to disassemble the interception sleeve. The outside of the interception sleeve is connected with multiple conical structures, which can improve the interception sleeve's ability to intercept and retain filamentous debris such as aquatic plants.

[0009] The utility model provides a hydroelectric generator with an anti-winding function, which has the following beneficial effects:

[0010] 1. The hydroelectric generator with anti-entanglement function can block and collect filamentous impurities such as water plants by arranging an interception sleeve on the front side of the turbine, thereby preventing such debris from being entangled on the turbine blades and causing difficulty in cleaning. A plurality of burrs are arranged on the outside of the interception sleeve to improve the interception efficiency. At the same time, the interception sleeve can be disassembled through the cooperation of the connecting rod and the interception sleeve, thereby providing convenience for its cleaning and facilitating manual operation.

[0011] 2. The hydroelectric generator with anti-entanglement function can block and collect debris such as aquatic plants by setting an interception sleeve on the front side of the turbine blade, thereby avoiding the problem of debris entangled on the turbine blade and being difficult to clean, and facilitating the daily maintenance and inspection of the hydroelectric generator.

[0012] 3. The hydroelectric generator with anti-winding function can realize the movable connection of the interception sleeve by using threads through the cooperation of the connecting rod and the interception sleeve, thereby facilitating the disassembly of the interception sleeve, providing convenience for the later cleaning of the interception sleeve and facilitating the operation of workers.

[0013] 4. In short, the hydroelectric generator with anti-entanglement function can achieve the effect of blocking and collecting debris such as water plants by arranging an interception sleeve on the front side of the turbine of the hydroelectric generator. At the same time, a plurality of spikes are arranged on the outside of the interception sleeve, which can improve the collection efficiency and greatly reduce the phenomenon of filamentous debris such as water plants adhering to the turbine blades, which is convenient for manual regular maintenance. Moreover, through the cooperation of the connecting rod and the interception sleeve, the interception sleeve can be easily disassembled and assembled, which provides convenience for manual cleaning.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-4 The utility model provides a technical solution: the hydroelectric generator includes a generator rotor, a support, an outer shell and a turbine blade 1, etc. The turbine blade 1 is connected to the engine rotor through a rotating shaft 2. The impact force of the external water flow causes the turbine blade 1 to rotate, thereby causing the rotating shaft 2 to drive the engine rotor to rotate to achieve the purpose of power generation. An interception sleeve 4 is arranged on the outside of the rotating shaft 2. The interception sleeve 4 has multiple staggered distributions, which will not affect the passage of water flow, and can also play the effect of intercepting water plants and other debris. The outside of the interception sleeve 4 is connected with multiple burr structures, which can improve the interception effect of the interception sleeve 4 on filamentary debris such as water plants, thereby greatly reducing the water plants and other debris entangled on the turbine blades 1, which is convenient for manual later cleaning.

[0021] See also Figure 1-4 The outer side of the rotating shaft 2 is connected with a plurality of staggeredly distributed connecting rods 3, the outer side of the connecting rod 3 is provided with threads, and the inner side of the intercepting sleeve 4 is also provided with corresponding threads, so that the intercepting sleeve 4 is movably connected to the outside of the connecting rod 3 through threads, and the outer side of the intercepting sleeve 4 is connected with a flat plate 41, which can facilitate the rotation of the intercepting sleeve 4 outside the connecting rod 3, providing convenience for manual operation, and also can facilitate the disassembly and assembly of the intercepting sleeve 4, provide convenience for the cleaning of the intercepting sleeve 4, and save the energy and time of workers.

[0022] To sum up, when the hydroelectric generator with anti-winding function is used, the hydroelectric generator is installed in the corresponding position and the corresponding lines are connected. The impact force of the water flow drives the turbine blades 1 to rotate, converting water energy into mechanical energy. The shaft 2 drives the rotor of the generator to convert mechanical energy into electrical energy for output. The output electrical energy is transmitted to the corresponding energy storage device or conversion device. When the shaft 2 rotates, the connecting rod 3 also rotates. The filamentous debris such as water plants in the water are blocked by the interception sleeve 4 and the burrs on the interception sleeve 4. When the hydroelectric generator is regularly inspected and maintained, the turbine blades 1 are stopped first, and then the interception sleeve 4 is rotated down and cleaned. After cleaning, the interception sleeve 4 is rotated back on the connecting rod 3.
