Description

Technical Field

[0001] The utility model relates to the technical field of power cabinets, in particular to a vibration-proof power cabinet. Background Art

[0002] The power cabinet refers to a combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters, high-voltage cabinets, transformers, etc. The main functions of the power cabinet are: to supply power to electrical equipment (provide power to equipment), start and stop electrical equipment (with start and stop buttons), detect the operation of equipment (set signal indicator lights, ammeters and voltmeters), and protect electrical equipment (circuit breakers); the power cabinet is a distribution cabinet; it is a distribution cabinet dedicated to providing power and control to power equipment (generally referring to electric motors).

[0003] At the construction site, for the installed power cabinet, due to the frequent vibrations generated during the construction process, the vibrations generated during the construction directly affect the electrical components installed inside the power cabinet. If the power cabinet itself does not have a good shockproof structure, it is used in an area with frequent vibrations. The electrical components inside the power cabinet are prone to damage. For example, a shockproof power cabinet with a Chinese publication number of CN214069293U includes a power cabinet part and a shock-absorbing installation part. The power cabinet part includes a cabinet body and a cabinet door. The cabinet door is installed on the front of the cabinet body. The shock-absorbing installation part includes a back plate, a bottom plate, a flexible connection component, a limit support component, a shock-absorbing support component and an elastic connection component. The back plate and the bottom plate are both arranged inside the cabinet body, and the bottom plate is fixedly connected to the bottom of the back plate;

[0004] This technical solution utilizes a first spring to provide shock absorption and support functions for the upper back panel and the electrical components on the front of the back panel. Although the spring can filter the vibration of the power cabinet, the spring itself will reciprocate when releasing energy. This movement will act on the power cabinet and aggravate the vibration of the power cabinet. Therefore, the shock absorption effect is relatively low. Utility Model Content

[0005] In order to solve the problem that the use of the first spring in the technical solution cited in the above background technology will aggravate the vibration of the power cabinet, the utility model provides a vibration-proof power cabinet.

[0006] The utility model is achieved in this way:

At the same time, the power cabinet is installed on the construction site to supply power to the electrical equipment on the construction site. When the vibration generated by the construction on the construction site acts on the outer cabinet, the vibration will compress the spring, thereby absorbing the ability generated by the vibration, thereby reducing the vibration amplitude of the inner cabinet. At this time, a relative displacement occurs between the piston and the connecting inner seat. This displacement will cause the damping oil in the connecting inner seat to flow from the first through hole into the connecting outer seat, and the damping oil in the connecting outer seat to flow from the second through hole into the connecting inner seat. Because the vibration is transmitted in the form of waves, when the vibration is not When it is transmitted to the outer cabinet, the compressed spring will reset and cause relative displacement between the piston and the connecting inner seat again. The displacement will cause the damping oil in the connecting inner seat to flow from the second through hole into the connecting outer seat, and the damping oil in the connecting outer seat to flow from the first through hole into the connecting inner seat. The flowing damping oil will rub against the first through hole, the second through hole, the piston, the inner and outer walls of the connecting inner seat, and the inner wall of the connecting outer seat, thereby converting the energy released by the spring due to reset into heat energy, so that the spring will not reciprocate, avoiding the continuous vibration of the inner cabinet due to the reciprocating motion of the spring, thereby improving the seismic resistance of the power cabinet.

[0009] Furthermore, a pair of rubber columns are connected between the two ends of the limiting block and the two sides of the limiting groove.

[0010] The beneficial effect of adopting the above further scheme is that the inner cabinet body is kept stable by the limit grooves and the limit blocks, and the inner cabinet body will not shake during vibration. At the same time, the rubber columns are used to prevent the limit blocks from directly contacting the limit grooves, and the rubber columns are used to further absorb the energy generated by the vibration.

[0011] Furthermore, a sealing bellows is connected between the top of the piston and the top surface of the second installation cavity, and the sealing bellows is sleeved on the outside of the plug rod.

[0012] The beneficial effect of adopting the above further solution is that the gap between the plug rod and the second mounting cavity is covered by the sealing bellows, thereby preventing the damping oil from flowing out of the gap.

[0013] Furthermore, a pair of connecting grooves are provided on one side of the front of the outer cabinet body, a rotating shaft is installed inside the connecting grooves, a connecting block rotating in the connecting groove is installed outside the rotating shaft, and cabinet doors are connected between the connecting blocks.

[0014] Furthermore, a plurality of heat dissipation slots are provided on both sides of the outer cabinet, and a plurality of heat dissipation holes are provided on both sides of the inner cabinet.

[0015] The beneficial effect of adopting the above further solution is that the heat generated by the operation of the electrical components and the heat generated by the flowing damping oil are dissipated by using the heat dissipation grooves and the heat dissipation holes.

[0016] Furthermore, a first inspection cover is provided on the top of the outer cabinet, a pair of fixing plates are installed on both sides of the first inspection cover, connecting holes are provided on the tops of the pair of fixing plates, four groups of threaded holes are provided on the top of the outer cabinet, and screws are connected between the connecting holes and the threaded holes.

[0017] Furthermore, a second inspection cover is provided on the top of the inner cabinet body, and fixing blocks are installed on both sides of the second inspection cover, and a first fixing hole is provided on one side of the fixing block, four groups of fixing grooves are provided on the top of the inner cabinet body, and a pair of second fixing holes penetrating the fixing grooves are provided on the side of the inner cabinet body, the fixing block and the fixing groove are engaged with each other, a fixing rod is slidably connected between the first fixing hole and the second fixing hole, and an anti-slip sleeve is provided on the outer side of the fixing rod.

A sliding hole is opened on the top of the connecting sleeve, and the connecting rods slide in the sliding hole, and the limiting plate slides in the connecting sleeve and is pressed against the inner top of the connecting sleeve.

[0019] The beneficial effect of adopting the above further scheme is that the internal space of the outer cabinet and the inner cabinet is expanded by using the openable first inspection cover and the second inspection cover, so that more electrical components or more areas of electrical components are exposed, so that users can inspect them. At the same time, the inner cabinet is lifted by squeezing the inner top of the limit plate and the connecting sleeve to prevent the entire weight of the inner cabinet from pressing on the rubber pad and preventing the spring from being completely compressed, so that the spring has a certain expansion and contraction space, and the piston is suspended inside the connecting inner seat.

[0020] The beneficial effects of the utility model are as follows: the utility model obtains an anti-vibration power cabinet through the above design, and the technical scheme causes relative displacement between the piston and the connecting inner seat through the expansion and contraction of the spring, so that the damping oil in the connecting inner seat flows from the second through hole into the connecting outer seat, and the damping oil in the connecting outer seat flows from the first through hole into the connecting inner seat; or the damping oil in the connecting inner seat flows from the first through hole into the connecting outer seat, and the damping oil in the connecting outer seat flows from the second through hole into the connecting inner seat, so that the flowing damping oil rubs against the first through hole, the second through hole, the piston, the inner and outer walls of the connecting inner seat, and the inner wall of the connecting outer seat, so as to convert the energy released by the spring due to resetting into heat energy, so that the spring will not reciprocate, and the situation that the inner cabinet body vibrates continuously due to the reciprocating motion of the spring is avoided, thereby improving the anti-vibration ability of the power cabinet.

The fixing block 1015 is engaged with the fixing grooves 1019, and a fixing rod 1010 is slidably connected between the first fixing hole 1016 and the second fixing hole 1020. The outer side of the fixing rod 1010 is covered with an anti-slip sleeve.

At the same time, the power cabinet is installed on the construction site to supply power to the electrical equipment on the construction site. When the vibration generated by the construction on the construction site acts on the outer cabinet 1001, the vibration will compress the spring 2012. Because the vibration is transmitted in the form of waves, when the vibration is not transmitted to the outer cabinet 1001, the compressed spring 2012 will reset. The compression and extension process of the spring 2012 will cause a relative displacement between the piston 2009 and the connecting inner seat 2006. This displacement will cause the damping oil in the connecting inner seat 2006 to flow from the first through hole 2007 into the connecting outer seat 2004. The damping oil in the connecting outer seat 2004 flows into the connecting inner seat 2006 from the second through hole 2008; or the damping oil in the connecting inner seat 2006 flows into the connecting outer seat 2004 from the second through hole 2008, and the damping oil in the connecting outer seat 2004 flows into the connecting inner seat 2006 from the first through hole 2007. The flowing damping oil rubs against the first through hole 2007, the second through hole 2008, the piston 2009, the inner and outer walls of the connecting inner seat 2006, and the inner wall of the connecting outer seat 2004, thereby converting the energy released by the spring 2012 due to the resetting into heat energy, so that the spring 2012 will not reciprocate, thereby avoiding the situation where the inner cabinet 1006 vibrates continuously due to the reciprocating motion of the spring 2012.
