Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Example 1
As shown in fig. 1-5, the utility model provides a technical solution: the utility model provides an outdoor explosion-proof resistance to compression type switch board of using, including switch board main part 1, switch board main part 1 includes shell 11, the inside of shell 11 is equipped with rock wool layer 13, one side that shell 11 was kept away from on rock wool layer 13 is equipped with steel keel layer 14, one side that rock wool layer 13 was kept away from on steel keel layer 14 is equipped with fiber cement composite steel plate layer 15, one side surface on rock wool layer 13 is equipped with damping ring 16, one side inner wall of damping ring 16 is equipped with spring 17, one side inner wall fixedly connected with blotter 18 that spring 17 was kept away from to damping ring 16, one side surface through connection that damping ring 16 was kept away from to blotter 18 has go-between 19, spring 17 keeps away from the fixed ring 111 of one end fixedly connected with of damping ring 16, one side surface of shell 11 is equipped with handle 12.
In this embodiment, because the inside of shell 11 comprises rock wool layer 13 and steel keel layer 14 and the compound steel sheet layer of fiber cement 15, when the switch board outside received the striking, the compound steel sheet layer of fiber cement 15 can at first receive the power, then with the even shock attenuation ring 16 who distributes one side surface connection of power, the inside of shock attenuation ring 16 is equipped with spring 17, spring 17 can at first cushion a part of impact force, remaining impact force can transmit to in blotter 18, blotter 18 comprises the polyurethane material, the polyurethane material has shock attenuation nature, shock attenuation ring 16 has digested external impact force, thereby constitute the bearing structure of resistance to deformation, can avoid the deformation of shell 11, if the inside of switch board appears great heat, can contact rock wool layer 13 at first, because the characteristic of rock wool layer 13, can play fire-retardant effect, and is practical.
Example 2
As shown in fig. 1-5, a pressure relief structure 2 is arranged on the outer surface of one side of the rock wool layer 13, the pressure relief structure 2 comprises a pressure relief piece main body 21, a circular groove 22 is formed in the pressure relief piece main body 21, a square groove 23 is formed in the outer surface of one side, away from the circular groove 22, of the pressure relief piece main body 21, a pressure relief membrane 24 is arranged at one end of the pressure relief piece main body 21, a mounting groove 25 is formed in the outer surface of one side of the rock wool layer 13, a rubber cushion ring 26 is arranged on the inner wall of one side of the mounting groove 25, and a dismounting convex block 27 is arranged at one end, away from the pressure relief membrane 24, of the pressure relief piece main body 21.
In this embodiment, rock wool layer 13's one side surface is equipped with a plurality of mounting groove 25, the user can install pressure release main part 21 to the inside of mounting groove 25, because rubber backing ring 26's elasticity is lower, put into mounting groove 25 at pressure release main part 21 after, rubber backing ring 26 can play the effect that blocks, avoid pressure release main part 21 from the mounting groove 25 internal slipping, when the switch board is inside to appear very big pressure, a large amount of gas at first can pass through circular recess 22 and square groove 23, strike the pressure release diaphragm 24 of pressure release main part 21 one end, be carved with on the pressure release diaphragm 24 and be favorable to torn nick, because critical pressure is great, when pressure release diaphragm 24 receives the interior high pressure draught extrusion of switch board or when assaulting, nick can split fast on the pressure release diaphragm 24, reach the mesh of leaking the explosion pressure.
The working principle is as follows:
as shown in fig. 1-5, since the interior of the housing 11 is composed of the rock wool layer 13, the steel keel layer 14 and the fiber cement composite steel plate layer 15, when the outside of the power distribution cabinet is impacted, the fiber cement composite steel plate layer 15 is firstly stressed and then evenly distributes the stress to the shock absorption ring 16 connected with the outer surface of one side, the spring 17 is arranged inside the shock absorption ring 16, the spring 17 firstly buffers a part of impact force, the rest impact force is transmitted to the shock absorption pad 18, the shock absorption pad 18 is composed of polyurethane material, the polyurethane material has shock absorption property, the shock absorption ring 16 digests the external impact force, thereby forming the deformation-resistant support structure, which can avoid the deformation of the housing 11, if the inside of the power distribution cabinet generates larger heat, the rock wool layer 13 is firstly contacted, due to the characteristics of the rock wool layer 13, the flame retardant effect can be achieved, and it is practical, the outer surface of one side of the rock wool layer 13 is provided with a plurality of mounting grooves 25, the user can install pressure relief piece main part 21 to the inside of mounting groove 25, because the elasticity of rubber backing ring 26 is lower, after pressure relief piece main part 21 is put into mounting groove 25, rubber backing ring 26 can play the effect of stopping, avoid pressure relief piece main part 21 from the landing in mounting groove 25, when the inside of switch board appears very big pressure, a large amount of gas can pass through circular recess 22 and square recess 23 at first, impact pressure relief piece 24 of pressure relief piece main part 21 one end, be carved with the nick that is favorable to tearing on pressure relief piece 24, because critical pressure is great, when pressure relief piece 24 receives the extrusion of high pressure draught in the switch board or assaults, nick on pressure relief piece 24 can split fast, reach the purpose of letting out explosion pressure, the one end of mounting groove 25 far away from pressure relief piece 24 is equipped with the lug simultaneously, when pressure relief piece 24 receives high pressure draught in the switch board and leads to its fracture, the lug structure at one end of the mounting groove 25 can prevent the pressure relief diaphragm 24 assembly from sliding out of the mounting groove 25 integrally to damage objects outside the power distribution cabinet, and when the pressure relief diaphragm 24 at one end of the pressure relief piece main body 21 is broken by air impact, a user can pry the groove of the dismounting lug 27 at one end of the pressure relief piece main body 21 to help the user to take out the broken pressure relief piece main body 21 and replace the pressure relief piece main body 21 with a new one, so that the purpose of protecting the shell 11 is achieved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may apply the equivalent embodiments modified or modified by the above technical contents disclosed as equivalent variations to other fields, but any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention will still fall within the protection scope of the technical solution of the present invention.
