Description

Technical Field

[0001] The utility model relates to the technical field related to electrical equipment, in particular to a protection mechanism for high and low voltage electrical equipment. Background Art

[0002] High and low voltage electrical equipment refers to generators, transformers, power lines, circuit breakers and other equipment in different voltage environments.

Although the electrical equipment can be isolated and protected, when an accident such as a collision between an external object and the cabinet occurs, the electrical equipment inside the cabinet will be affected, which may cause the electrical equipment to be installed loose or damaged, affecting the normal use of the electrical equipment, and reducing the practicality of the existing high and low voltage electrical equipment. The utility model patent includes an installation cabinet, a main body component is installed on the outside of the installation cabinet, a protection component is installed on the bottom of the installation cabinet, the main body component includes a protection cover fixedly connected to the top of the installation cabinet, a mounting frame is fixedly connected to the inside of the installation cabinet, and a cabinet door is hinged on the front of the installation cabinet through a hinge. The protection component includes two buffer plates respectively slidably connected to the left and right sides of the installation cabinet, and two No. 1 telescopic rods are fixedly connected to the opposite sides of the two buffer plates. A protection frame is fixedly connected between the opposite sides of the No. 1 telescopic rods on the left and right sides, and two L-shaped blocks are fixedly connected to the bottom of the installation cabinet.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 6 The utility model describes the above technical solution in detail through the following embodiments:

[0027] A protection mechanism for high and low voltage electrical equipment, comprising: a protection box 1; a lifting block 2 is fixedly connected to the bottom of the protection box 1, a buffer box 3 is slidably connected to the bottom outer surface of the lifting block 2, a mounting plate 4 is fixedly connected to the bottom of the buffer box 3, two first fixing plates 5 are fixedly connected to the bottom of the lifting block 2, a cylinder 6 is arranged at the bottom of the first fixing plate 5, a second fixing plate 7 is arranged at the bottom of the cylinder 6, the second fixing plate 7 is fixedly connected to the mounting plate 4, and matching buffer plugs 8 are arranged at both ends of the cylinder 6, and the two buffer plugs 8 are fixedly connected to the first fixing plate 5 and the second fixing plate 7 respectively; auxiliary mechanisms 9 for improving the buffering performance of the protection box 1 are arranged on both sides of the cylinder 6; and the inner sides of the protection box 1 are provided with a plurality of means for improving the heat dissipation of the electrical equipment. The air cooling mechanism 10 has high performance. When the protection box 1 is hit by an external object, it will control the internal part of the buffer box 3 to move downward by its own weight. The protection box 1 moves and drives the lifting block 2. The lifting block 2 drives the first fixed plate 5. The first fixed plate 5 moves downward and squeezes the gas inside the cylinder 6 with the second fixed plate 7. The gas generates elastic buffering by compressing itself. At the same time, the downward movement of the first fixed plate 5 further improves the buffering effect of the protection box 1 through the auxiliary mechanism 9, and the protection box 1 is buffered by the cooperation of the auxiliary mechanism 9 and the gas buffer, which improves the buffering and force release function of the protection box 1 when it is hit by an external object, and reduces the probability of the internal electrical equipment being loosened or damaged when the protection box 1 is hit.

[0028] like Figure 2 , Figure 4 and Figure 5As shown, the auxiliary mechanism 9 includes: guide rails 11 are fixedly connected on both sides of the cylinder 6, and moving blocks 12 are slidably connected inside the guide rails 11, and damping pads 13 are fixedly connected to the moving blocks 12 near the guide rails 11, and first rotating shafts 14 are fixedly connected on both sides of the moving blocks 12, and the first connecting rods 15 are rotatably connected to the outer surface of the first rotating shaft 14 away from the moving blocks 12, and second connecting rods 16 are arranged between the first connecting rod 15 and the moving blocks 12, and the second connecting rods 16 are rotatably connected to the first rotating shaft 14 respectively; the bottom ends of the first connecting rods 15 are rotatably connected to the first connecting blocks 18 through the second rotating shaft 17, and the first connecting blocks 18 are fixedly connected to the second fixed plate 7, and the top ends of the second connecting rods 16 are rotatably connected to the second connecting blocks 20 through the third rotating shaft 19, and the second connecting blocks 20 are fixedly connected to the first fixed plate 5; the moving block 12 The interior is provided with an elastic mechanism 21 for improving the buffering performance. When the protection box 1 drives the lifting block 2 to move downward, the lifting block 2 drives the first fixed plate 5, and the first fixed plate 5 drives the second connecting block 20. The second connecting block 20 squeezes the top of the second linkage rod 16 through the third rotating shaft 19, so that the bottom end of the second linkage rod 16 pushes the moving block 12 to slide inside the guide rail 11 through the first rotating shaft 14. The moving block 12 drives the first linkage rod 15 through the first rotating shaft 14 during movement. The first linkage rod 15 rotates slightly through the cooperation of the second rotating shaft 17 and the first connecting block 18, so that the first fixed plate 5 and the second fixed plate 7 drive the buffer plug 8 to compress the gas inside the cylinder 6. The gas generates elastic buffering through compression itself. While the moving block 12 moves, it is also buffered by the elastic mechanism 21.

[0029] like Figure 4 and Figure 5 As shown, the elastic mechanism 21 includes: two slide rods 22 are slidably connected inside the moving block 12, and both ends of the slide rods 22 are fixedly connected to the guide rail 11; two springs 23 are arranged on the side of the moving block 12 away from the cylinder 6, and the springs 23 are respectively sleeved on the outer surface of the slide rod 22. When the moving block 12 slides on the surface of the slide rod 22 inside the guide rail 11, the spring 23 is squeezed by the cooperation of the guide rail 11, and the spring 23 buffers the moving block 12 through its own elastic force, thereby achieving the purpose of buffering the protection box 1.

[0030] like Figure 5 As shown, a matching sealing gasket 24 is provided at one end of the buffer plug 8 located inside the cylinder 6, and the sealing gasket 24 is fixedly connected to the buffer plug 8, respectively, thereby improving the sealing performance between the buffer plug 8 and the cylinder 6 and avoiding the situation in which the buffering performance of the device is weakened due to air leakage.

[0031] like Figure 3As shown, both sides of the bottom of the lifting block 2 are fixedly connected with limit sliders 25, and the buffer box 3 is provided with corresponding sliding grooves 26 near the limit sliders 25. The limit sliders 25 are slidably connected with the sliding grooves 26. The lifting block 2 slides in the sliding grooves 26 inside the buffer box 3 through the limit sliders 25, so that the moving stroke of the lifting block 2 can be limited.

[0032] like Figure 1 and Figure 6 As shown, the air cooling mechanism 10 includes: exhaust ports 27 are provided on both sides of the protection box 1, and dustproof nets 33 are fixedly connected inside the exhaust ports 27; motors 28 are provided near the dustproof nets 33 of the protection box 1, and the output ends of the motors 28 are fixedly connected to heat dissipation blades 29, and the four corners of the motors 28 are fixedly connected to the protection box 1 through L-shaped rods 30. When the motor 28 is started, the output ends of the motors 28 drive the heat dissipation blades 29. The heat dissipation blades 29 rotate to blow the high temperature generated by the operation of the electrical equipment inside the protection box 1 from the exhaust ports 27 to the outside of the protection box 1, so as to quickly dissipate the heat of the electrical equipment inside the protection box 1, thereby reducing the probability of the electrical equipment inside the protection box 1 being burned due to the high temperature generated during operation.

[0033] like Figure 6 As shown, a plurality of drainage holes 31 with air intake function are evenly provided at the bottom of the protection box 1, and a plurality of through holes 32 are provided on both sides of the bottom of the buffer box 3. The through holes 32 cooperate with the drainage holes 31, and the water entering the protection box 1 can flow into the interior of the buffer box 3 through the drainage holes 31, and then be discharged to the outside of the device through the through holes 32. When the air cooling mechanism 10 is running, the outside air can enter the interior of the protection box 1 through the through holes 32 and the drainage holes 31 in turn, thereby achieving the effect of air intake.

[0034] Working principle: When the protection box 1 is hit by an external object, it controls the interior of the buffer box 3 to move downward by its own weight. When the protection box 1 moves, it drives the lifting block 2, the lifting block 2 drives the first fixed plate 5, the first fixed plate 5 drives the second connecting block 20, the second connecting block 20 squeezes the top of the second linkage rod 16 through the third rotating shaft 19, so that the bottom end of the second linkage rod 16 pushes the moving block 12 to slide inside the guide rail 11 through the first rotating shaft 14, and the moving block 12 drives the first connecting rod 16 through the first rotating shaft 14. The linkage rod 15, the first linkage rod 15 rotates slightly through the cooperation of the second rotating shaft 17 and the first connecting block 18, so that the first fixed plate 5 and the second fixed plate 7 drive the buffer plug 8 to compress the gas inside the cylinder 6. The gas generates elastic buffering through compression itself, and while the moving block 12 slides on the surface of the sliding rod 22 inside the guide rail 11, the spring 23 is squeezed through the cooperation of the guide rail 11. The spring 23 buffers the moving block 12 through its own elastic force, thereby achieving the purpose of buffering the protection box 1.

[0035] When the electrical equipment inside the protection box 1 is running, the motor 28 is started, and the output end of the motor 28 drives the heat dissipation fan blades 29. The heat dissipation fan blades 29 rotate to blow the high temperature generated by the operation of the electrical equipment inside the protection box 1 through the exhaust port 27 to the outside of the protection box 1, so as to quickly dissipate the heat of the electrical equipment inside the protection box 1 and reduce the probability of the electrical equipment inside the protection box 1 being burned due to the high temperature generated during operation.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
