Description

Technical Field

[0001] This utility model relates to the field of hydro-generators, specifically a single-cylinder double-piston hydro-generator brake with a dust collection device. Background Technology

[0002] A hydro-generator is a power generation device that converts water energy into electrical energy. Existing hydro-generator brakes are all single-cylinder, single-piston brakes, with high-pressure oil and brake air mixed in one working chamber. When braking, dust from the brake plate falls onto the lower frame of the turbine. When the unit starts to rotate, the dust rises and causes damage to the generator's stator and rotor. To address this, we have proposed a single-cylinder, double-piston hydro-generator brake with a dust collection device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a single-cylinder double-piston water turbine generator brake with a dust collection device, which solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a single-cylinder double-piston water turbine generator brake with a dust collection device, comprising a base, wherein a lower piston is fixedly installed inside the base near the bottom, and a dust brush is rotatably installed on the top of the base near one end, and further comprising:

[0005] Dust collection assembly, which is mounted on the base.

[0006] Preferably, the dust collection assembly includes a dust brush and a dust collection device. The dust brush is fixedly installed on the top of the base, and a dust collection device for collecting dust is fixedly installed at one end of the bottom of the dust brush.

[0007] Preferably, a pneumatic brake port is provided on one side of the base, and a pneumatic return port is provided on the other side of the base corresponding to the pneumatic brake port.

[0008] Preferably, the base has an oil top opening near the bottom on its front side.

[0009] Preferably, a brake block is fixedly provided on the top inner wall of the base, a brake plate is slidably installed on the bottom of the brake block, and a pressure ring is fixedly installed on the bottom of the brake plate.

[0010] Preferably, a bushing is fixedly connected to the bottom of the pressure ring, and a semi-circular key is fixedly connected to one side of the bushing corresponding to the lower part of the brake plate.

[0011] Preferably, an upper piston is slidably mounted on the inner wall of the brake block, a round nut is fixed on the inner wall of the base corresponding to the side of the upper piston, a handle is fixed on the side of the round nut, and a limit switch is fixed on the side of the base.

[0012] Compared with the prior art, this utility model provides a single-cylinder double-piston water turbine generator brake with a dust collection device, which has the following beneficial effects:

[0013] 1. The single-cylinder double-piston hydro-generator brake with dust collection device separates the oil and gas working chambers, preventing high-pressure oil from entering the air brake integrated valve and increasing the service life of the brake integrated valve.

[0014] 2. The single-cylinder double-piston hydro-generator brake with dust collection device can collect dust after braking by adding a dust collector. The dust collection device can reduce the wear and corrosion of the generator brake by dust, thereby extending the service life of the equipment and reducing maintenance and replacement costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 A single-cylinder double-piston hydro turbine generator brake with a dust collection device includes a base 11, a lower piston 12 fixedly installed inside the base 11 near the bottom, and a dust brush 6 rotatably installed on the top of the base 11 near one end. It also includes:

[0021] A dust collection assembly is mounted on the base 11.

[0022] The dust collection assembly includes a dust brush 6 and a dust collection device 7. The dust brush 6 is fixedly installed on the top of the base 11. The dust collection device 7 for collecting dust is fixedly installed at one end of the bottom of the dust brush 6. When the dust collection device 7 is powered on, it starts to generate vacuum suction and collects the dust generated by the brake into the dust collection box of the dust collection device 7.

[0023] A pneumatic brake port is provided on one side of the base 11, and a pneumatic return port is provided on the other side of the base 11 corresponding to the pneumatic brake port. When the braking ends, the compressed air in the pneumatic brake port exits; the compressed air enters from the pneumatic return port and pushes the upper piston 8 to move back, the brake plate 2 of the brake disengages from the brake block of the water turbine, and at the same time the dust collection device 7 is de-energized and shuts down.

[0024] The base 11 has an oil jack opening near the bottom on the front. When the unit needs to be lifted, high-pressure oil is introduced into the oil jack opening of the brake, pushing the lower piston 12 forward, causing the piston of the overall brake to move forward, and the brake plate 2 to contact the water turbine brake block, thus raising the entire unit.

[0025] A brake block 1 is fixedly installed on the top inner wall of the base 11. A brake plate 2 is slidably installed on the bottom of the brake block 1. A pressure ring 3 is fixedly installed on the bottom of the brake plate 2. When the unit needs to brake, compressed air is introduced into the air brake port of the brake, pushing the upper piston 8 to move forward. The brake plate 2 on the brake block 1 rubs against the brake block of the water turbine, causing it to stop.

[0026] A bushing 5 is fixed to the bottom of the pressure ring 3, and a semi-circular key 4 is fixed to one side of the bushing 5 corresponding to the lower part of the brake plate 2.

[0027] The inner wall of the brake block 1 is slidably fitted with an upper piston 8. The inner wall of the base 11 is fixed with a round nut 9 corresponding to the side of the upper piston 8. The side of the round nut 9 is fixed with a handle 10. The side of the base 11 is fixed with a limit switch 13. Compressed air enters from the air reset port and pushes the upper piston 8 to move back.

[0028] Working Principle: Braking: When the unit needs to brake, compressed air is introduced into the air brake port of the brake, pushing the upper piston 8 forward. The brake plate 2 on the brake block 1 rubs against the brake block of the turbine, stopping the machine. At the same time, the dust collection device 7 is energized and starts to generate vacuum suction, collecting the dust generated by braking into the dust collection box of the dust collection device 7; Reset: When braking ends, the compressed air in the air brake port is released; compressed air enters from the air reset port, pushing the upper piston 8 back. The brake plate 2 of the brake disengages from the brake block of the turbine, and the dust collection device 7 is de-energized and shuts down; Oil Lifting: When the unit needs to be lifted, high-pressure oil is introduced into the oil lifting port of the brake, pushing the lower piston 12 forward, causing the piston of the entire brake to move forward. The brake plate 2 contacts the turbine brake block, raising the entire unit.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
