Description

Technical Field

[0001] The utility model relates to the technical field of generator vibration reduction, in particular to a generator base vibration reduction device. Background Art

[0002] Generators are important equipment in modern industry and power systems. Their function is to generate electricity for use. However, generators often generate vibrations during operation, which not only reduces the performance of the generator, but may also have a negative impact on the surrounding environment and other equipment. Existing generator bases often lack shock absorption functions, or their shock absorption effects are not ideal. When the generator vibrates, the base is prone to slip, which seriously affects the stability and work efficiency of the generator. Since the staff cannot monitor, if the generator itself fails and causes a large vibration during operation, it is difficult for the staff to detect it in time, which is easy to induce safety accidents.

[0003] Therefore, it is necessary to provide a new generator base shock absorbing device to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a generator base shock absorbing device.

[0005] The generator base shock absorbing device provided by the utility model comprises an air storage cylinder, both ends of the air storage cylinder are inserted with compression rods which are slidably connected, and the two compression rods are both installed with a reduction assembly, and the reduction assembly comprises a sleeve, a sliding rod which is slidably connected is inserted on the sleeve, and a side pressure piece for pushing the compression rod to compress the gas inside the air storage cylinder is also installed on the sleeve;

[0006] An early warning component is installed on the gas cylinder, and the early warning component includes a vertical pipe, which is fixedly installed in the middle of the gas cylinder and connected to the gas cylinder, and a voice alarm is fixedly installed on the outer tube wall of the vertical pipe, a contact switch is fixedly installed at the pipe opening at the top of the vertical pipe, and a top rod for opening the contact switch is installed in the vertical pipe.

[0007] Preferably, a slidably connected conical piston is installed in the vertical tube, the push rod is fixedly installed on the upper surface of the conical piston and is coaxially arranged with the conical piston, a spring A is fixedly installed on the upper surface of the conical piston, and the other end of the spring A is fixedly connected to the inner top wall of the vertical tube.

[0008] Preferably, the bottom tube body of the vertical tube is funnel-shaped, and the conical piston is adapted to the funnel-shaped tube body of the vertical tube.

[0009] Preferably, the side pressure member includes a rotating seat, on which are mounted two rotatably connected rotating plates, and both of the rotating plates pass through waist-shaped holes formed in the side walls of the sleeve and extend into the sleeve, and both ends of the two rotating plates extending into the sleeve are mounted with rotatably connected rotating frames, and the two rotating frames are respectively fixedly mounted on the insertion end of the sliding rod and the inner bottom wall of the sleeve, and a spring B is fixedly mounted between the two rotating frames.

[0010] Preferably, a connecting head is fixedly mounted on the rotating seat, and the connecting head is fixedly connected to the compression rod.

[0011] Preferably, the compression rod is inserted into the air storage cylinder and a piston disc is fixedly mounted on the rod head.

[0012] Compared with the related art, the generator base shock absorbing device provided by the utility model has the following beneficial effects:

[0013] 1. In the utility model, when the generator base vibrates, the sliding rod slides down along the sleeve, so the spring B between the two rotating frames is compressed. At the same time, the two rotating plates extend to the outside of the sleeve and drive the gas in the gas reservoir to be compressed. The compressed gas in the gas reservoir has a damping effect on the spring B, so it effectively has a buffering and shock-absorbing effect on the generator base. The compressed gas in the gas reservoir also slides upward along the vertical pipe against the conical piston. At this time, the spring A is also compressed. The compressed spring A cooperates with the compressed gas to effectively enhance the damping effect on the spring B, thereby further alleviating the amplitude of the generator base.

[0014] 2. When the generator base vibrates strongly, the utility model drives the piston disk to compress the gas in the air storage cylinder. At this time, the compressed air drives the conical piston to slide upward along the vertical pipe and compress the spring A until the push rod on the conical piston contacts the contact switch. At this time, the voice alarm gives a voice alarm, so the staff can stop in time and check whether the generator needs maintenance, reducing the risk of accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] See also Figures 1 to 4 An embodiment of the utility model provides a generator base shock absorbing device, which includes an air storage cylinder 1, an early warning component 2 and an amplitude reduction component 3.

[0023] In the embodiments of the present invention, please refer to Figures 1 to 4 Both ends of the gas cylinder 1 are inserted with a slidably connected compression rod 11, and the compression rod 11 is inserted into the gas cylinder 1 and a piston disc 12 is fixedly installed on the rod head, and the two compression rods 11 are installed with a reduction assembly 3;

[0024] The reduction component 3 includes a sleeve 31, a sliding rod 32 slidably connected to the sleeve 31 is inserted on the sleeve 31, and a side pressure piece 33 for pushing the compression rod 11 to compress the internal gas of the air storage cylinder 1 is also installed on the sleeve 31, and the side pressure piece 33 includes a rotating seat 331, and two rotating plates 332 rotatably connected are installed on the rotating seat 331, and the two rotating plates 332 both pass through the waist-shaped hole 31a opened on the side wall of the sleeve 31 and extend into the sleeve 31, and the ends of the two rotating plates 332 extending into the sleeve 31 are both installed with a rotating frame 333 rotatably connected, and the two rotating frames 333 are respectively fixedly installed on the inserted end of the sliding rod 32 and the inner bottom wall of the sleeve 31, and a spring B334 is fixedly installed between the two rotating frames 333, and a connecting head 335 is also fixedly installed on the rotating seat 331, and the connecting head 335 is fixedly connected to the compression rod 11.

[0025] Furthermore, two sets of the shock absorbing devices are installed on the generator base, and the two sets of shock absorbing devices are kept symmetrically distributed, so that the sleeve 31 and the sliding rod 32 constitute the supporting leg structure of the generator base, and the air storage cylinder 1 cooperates with the compression rod 11 arranged on both sides to form a connecting cross frame structure of the two supporting leg structures.

[0026] It should be noted that: when the generator base vibrates, the sliding rod 32 slides down along the sleeve 31, so the sliding rod 32 pushes the rotating frame 333 connected to it to slide toward the bottom of the sleeve 31, so that the spring B334 between the two rotating frames 333 is compressed, and at the same time, the two rotating plates 332 extend toward the outside of the sleeve 31, so that the compression rod 11 slides toward the middle cylinder of the air cylinder 1, so that the piston disk 12 compresses the gas in the air cylinder 1, and the compressed gas in the air cylinder 1 has a damping effect on the spring B334, thereby effectively buffering and reducing shock on the generator base.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 4 An early warning component 2 is installed on the gas cylinder 1, and the early warning component 2 includes a vertical tube 21, which is fixedly installed in the middle of the gas cylinder 1 and communicated with the gas cylinder 1, and a voice alarm 26 is fixedly installed on the outer tube wall of the vertical tube 21, a contact switch 25 is fixedly installed at the pipe mouth at the top of the vertical tube 21, and a push rod 23 for opening the contact switch 25 is installed in the vertical tube 21, a slidingly connected conical piston 22 is installed in the vertical tube 21, the push rod 23 is fixedly installed on the upper surface of the conical piston 22 and is coaxially arranged with the conical piston 22, a spring A24 is fixedly installed on the upper surface of the conical piston 22, and the other end of the spring A24 is fixedly connected to the inner top wall of the vertical tube 21.

[0028] It should be noted that: when the generator base vibrates, the compressed gas in the gas reservoir 1 also presses against the conical piston 22 to slide upward along the vertical pipe 21, and the spring A24 is also compressed at this time. The compressed spring A24 cooperates with the compressed gas to effectively enhance the damping effect of the spring B334, thereby further alleviating the amplitude of the generator base;

[0029] When the generator base vibrates strongly, the piston disc 12 is driven to compress the gas in the air storage cylinder 1. At this time, the compressed air drives the conical piston 22 to slide upward along the vertical pipe 21 and compress the spring A24 until the push rod 23 on the conical piston 22 abuts against the contact switch 25. At this time, the voice alarm 26 gives a voice alarm, so the staff can stop the generator in time and check whether it needs maintenance, thereby reducing the risk of accidents.

[0030] Furthermore, the bottom tube body of the vertical tube 21 is funnel-shaped, and the conical piston 22 is adapted to the funnel-shaped tube body of the vertical tube 21 , thereby preventing the conical piston 22 from falling from the bottom of the vertical tube 21 into the air storage cylinder 1 .

[0031] The gas stored in the gas storage cylinder 1 can be nitrogen or an inert gas that is harmless and pollution-free, and is not limited here.

[0032] The working principle of the generator base shock absorbing device provided by the utility model is as follows:

[0033] Two sets of the shock absorbing devices are installed on the generator base, and the two sets of shock absorbing devices are kept symmetrically distributed, so that the sleeve 31 and the sliding rod 32 constitute the supporting leg structure of the generator base, and the air reservoir 1 cooperates with the compression rods 11 arranged on both sides to form a connecting cross frame structure of the two supporting leg structures;

[0034] When the generator base vibrates, the sliding rod 32 slides down along the sleeve 31, so the sliding rod 32 pushes the rotating frame 333 connected thereto to slide toward the bottom of the sleeve 31, so that the spring B334 between the two rotating frames 333 is compressed, and at the same time, the two rotating plates 332 extend toward the outside of the sleeve 31, so that the compression rod 11 slides toward the middle cylinder of the gas cylinder 1, so that the piston plate 12 compresses the gas in the gas cylinder 1, and the compressed gas in the gas cylinder 1 has a damping effect on the spring B334, thereby effectively buffering and reducing shock on the generator base, and the compressed gas in the gas cylinder 1 also presses against the conical piston 22 to slide upward along the vertical pipe 21, at this time, the spring A24 is also compressed, and the compressed spring A24 cooperates with the compressed gas to effectively enhance the damping effect on the spring B334, thereby further alleviating the amplitude of the generator base;

[0035] When the generator base vibrates strongly, the piston disc 12 is driven to compress the gas in the air storage cylinder 1. At this time, the compressed air drives the conical piston 22 to slide upward along the vertical pipe 21 and compress the spring A24 until the push rod 23 on the conical piston 22 abuts against the contact switch 25. At this time, the voice alarm 26 gives a voice alarm, so the staff can stop the generator in time and check whether it needs maintenance, thereby reducing the risk of accidents.
