Description
Technical field
The utility model relates to a kind of block terminal, particularly relates to a kind of explosion-proof type block terminal.
Background technology
Explosion-proof type block terminal is equipment very important in modern industry, such as in factory, ore deposit underground work, electric energy is provided for giving each plant equipment, especially in mine operation, explosion-proof type block terminal is one of critical facility of safety in production, but there is following weak point in existing block terminal: first, due in ore deposit underground work, damp is there is in mine, such as gas, the mixture of dust and gas, existing block terminal is due to its poor sealing, these damps still easily enter into block terminal, because the equipment in block terminal is as circuit breaker etc., although all adopt explosion-proof type element, but its joint is owing to can produce electric spark in the course of work, thus light the explosivity that enters other, thus cause security incident, secondly, the heat dispersion of existing block terminal is not good, thus causes the components and parts work extremely unstable in block terminal, affects production operation.
Therefore, need to propose a kind of explosion-proof type block terminal be applicable under the hazardous environments such as mine newly, block terminal inner space can be made to keep good isolation performance with outside, thus effectively prevent outside gas or moisture from entering into block terminal inside, prevent from causing security incident and steam to cause damage to the components and parts in block terminal.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of explosion-proof type block terminal, block terminal inner space can be made to keep good isolation performance with outside, thus effectively prevent outside gas or moisture from entering into block terminal inside, prevent from causing security incident and steam to cause damage to the components and parts in block terminal.
A kind of explosion-proof type block terminal that the utility model provides, comprise the box body and lid that adopt explosion-proof lamp to make, described tray interior is provided with dividing plate and tray interior is separated into multiple cavity volume, the sidewall of described lid is provided with embedded groove, described embedded groove is arranged in the mode perpendicular to caping, and the opening part of the sidewall of described box body is embedded in described embedded groove.
Further, sealing gasket is provided with in described embedded groove.
Further, the cross section of described sealing gasket is U-shaped structure, and the opening of sealing gasket is towards the contrary direction of the caping of lid, is provided with projection inside the opening part of sealing gasket.
Further, the ventilation duct of through box body is provided with bottom described box body.
Further, the arranged outside of described ventilation duct has fin, and the inner side of described ventilation duct is provided with helical fin.
The beneficial effects of the utility model: explosion-proof type block terminal of the present utility model, block terminal inner space can be made to keep good isolation performance with outside, thus effectively prevent outside gas or moisture from entering into block terminal inside, prevent from causing security incident and steam to cause damage to the components and parts in block terminal; And the radiating effect of block terminal can be ensured, the work that the element in guarantee block terminal is continual and steady.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, a kind of explosion-proof type block terminal that the utility model provides, comprise the box body 1 and lid 7 that adopt explosion-proof lamp to make, described box body 1 inside is provided with dividing plate 2 and box body 1 interior separation is become multiple cavity volume 4, the number of cavity volume sets according to actual needs, Fig. 1 merely illustrates wherein two, the sidewall of described lid 1 is provided with embedded groove 4, described embedded groove 4 is arranged in the mode perpendicular to caping, namely the opening direction of embedded groove is towards the contrary direction of caping, the opening part of the sidewall of described box body 1 is embedded in described embedded groove 4, described cavity volume is for holding circuit breaker, the operation elements such as electric energy meter, the cavity volume of isolation can ensure operationally can not produce mutual interference between each element, explosion-proof type block terminal of the present utility model, block terminal inner space can be made to keep good isolation performance with outside, thus effectively prevent outside gas or moisture from entering into block terminal inside, prevent from causing security incident and steam to cause damage to the components and parts in block terminal, wherein, explosion-proof lamp is that alkyd resin is closed in glass fiber reinforcement insatiable hunger.
In the present embodiment, be provided with sealing gasket 5 in described embedded groove 4, by the effect of sealing gasket, after the sidewall of the opening part of box body is embedded into embedded groove, sealing gasket effectively can ensure the isolation performance inside and outside box body.
In the present embodiment, the cross section of described sealing gasket is U-shaped structure, and the opening of sealing gasket 5 is towards the contrary direction of the caping of lid, protruding 6 are provided with, by this structure, when the sidewall of the opening part of box body is embedded in the sealing gasket of U-shaped structure inside the opening part of sealing gasket 5, the extruding of some strength can be formed to the bottom of sealing gasket, thus increase sealing property, and sidewall that is protruding and box body fits tightly, and further enhancing the sealing property of tray interior.
In the present embodiment, the ventilation duct 8 of through box body 1 is provided with bottom described box body 1, the layout of ventilation duct 8, while ensureing the sealing property in box body, air flows through ventilation duct, can take away the heat that in box body, emergency electric supply unit produces, and ensures the heat dispersion of block terminal, wherein the outside of ventilation duct and box body are tightly connected, and prevent from occurring gap inside and outside box body.
In the present embodiment, the arranged outside of described ventilation duct 8 has fin 10, the inner side of described ventilation duct 8 is provided with helical fin 9, by this structure, fin can increase the contact area of the hot-air of tray interior, and the helical fin in outside can increase and the cold air contact area flow through, the radiating effect greatly strengthened, and effectively avoid the convection current of the air inside and outside box body to cause interference to element in box body, play good explosion-proof effect, wherein fin is semicircular configuration, as shown in Figure 1, ventilation duct is provided with the position of fin and fin is exposed to tray interior, fit tightly bottom other positions of ventilation duct and box body, to ensure the air-tightness of tray interior.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
