The rotating rod is arranged at the top of the dustproof housing, and the bottom of the rotating rod is connected to the limiting plate. A rectangular groove is opened on the front side of the dustproof housing. For this mine flameproof switch convenient for heat dissipation, a liquid pump is provided. Under the action of the liquid pump, the water in the water tank will enter the heat exchange pipe network to absorb the heat dissipated when the mine flameproof switch body works, and the water that absorbs the heat will flow back to the water tank through the drainage pipe, so that the heat dissipated by the mine flameproof switch body can be taken away by the flowing water, and further facilitate the heat dissipation of the mine flameproof switch body.

[0005] Although the above-mentioned mine flameproof switch convenient for heat dissipation dissipates heat from the switch body through the heat dissipation mechanism, when fixing the switch body, the switch body is directly limited and fixed through the limiting plate. However, this fixing method cannot provide seismic protection for the switch body, and the switch is prone to damage due to vibration, and there are still deficiencies in the protection of the switch. Summary of the Utility Model

[0006] In order to solve the problem that the above-mentioned mine flameproof switch convenient for heat dissipation cannot provide seismic protection for the switch body and there are still deficiencies in the protection of the switch, the utility model proposes a protection device for a mine switch.

An outer shell is arranged outside the switch body. And on both the upper and lower sides of the switch body inside the outer shell, there are support frames elastically pressed on the switch body. The upper end of the outer shell is open, and a cover is installed at the opening. At both the left and right ends of the cover, there are locking screws threadedly installed on the outer shell. A fan is installed at the right end of the outer shell, and a net plate is installed at the port facing the outside of the fan. The left end face of the outer shell is provided with evenly distributed air outlet holes.

[0008] As a preferred solution, a bottom plate is arranged on the lower side of the outer shell, and the lower side of the outer shell and the bottom plate are fixedly connected by a plurality of support plates.

[0009] As a preferred solution, at both the left and right sides of the cover, there are lock edges through which the locking screws are inserted, and a clamping ring is fixed on the lower side of the cover. A second installation groove is opened at the top inside the clamping ring.

[0010] As a preferred solution, a pressing block is fixed at the upper end of the locking screw, and a rotating handle is fixed at the upper end of the pressing block.

[0011] As a preferred solution, the support frame includes a fixing plate. On the side of the fixing plate facing the switch body, there are a plurality of evenly distributed support columns fixed, and the fixing plate and the support columns are integrally formed rubber products.

[0012] As a preferred solution, a first installation groove is opened at the bottom inside the outer shell, and connection plates are fixed at positions near the upper ends on both the left and right sides of the outer shell.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] By blowing air into the outer shell through the fan, the heat generated by the switch body is taken away and discharged through the air outlet holes, so as to dissipate heat from a larger area of the switch body, thereby realizing heat dissipation protection for the switch body. At the same time, the support frames on both the upper and lower sides are elastically pressed on the switch body under the extrusion of the cover, thereby realizing anti-seismic protection for the switch body, having a better protection effect, and greatly extending the service life of the switch body.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] It should be noted that the terms used here are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0023] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in the subsequent drawings.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0025] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features.

Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0026] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0027] Such as Figure 1As shown in the figure, a protection device for a mine switch includes a switch body 4. An outer shell 1 is arranged outside the switch body 4. A bottom plate 7 is arranged on the lower side of the outer shell 1, and the lower side of the outer shell 1 and the bottom plate 7 are fixedly connected by a plurality of support plates 6. The bottom plate 7 and the support plates 6 are used for fixedly supporting the outer shell 1. On the upper and lower sides of the switch body 4 inside the outer shell 1, there are installed support frames 5 that are elastically pressed against the switch body 4. The upper end of the outer shell 1 is open, and a cover 3 is installed at the opening. Locking screws 2 are inserted through the left and right ends of the cover 3 and are threadedly installed on the outer shell 1. A fan 12 is installed at the right end of the outer shell 1, and a net plate is installed at the outer port facing the fan 12. Air outlet holes 11 are evenly distributed on the left end face of the outer shell 1. By blowing air into the outer shell 1 through the fan 12, the heat generated by the switch body 4 is taken away and discharged through the air outlet holes 11, so as to dissipate heat from a larger area of the switch body 4, thereby realizing heat dissipation protection for the switch body 4. At the same time, the support frames 5 on the upper and lower sides are elastically pressed against the switch body 4 under the extrusion of the cover 3, thereby realizing anti-seismic protection for the switch body 4, having a good protection effect, and greatly extending the service life of the switch body 4.

[0028] As Figure 2 shown, on both the left and right sides of the cover 3, there are fixed edge locks 32 through which the locking screws 2 are inserted, and a clamping ring 33 is fixed on the lower side of the cover 3 for being inserted into the inner side of the upper port of the outer shell 1 to achieve installation cooperation. A second installation groove 31 is opened at the inner top of the clamping ring 33 for clamping and fixing the upper support frame 5.

[0029] As Figure 3 shown, a pressing block 22 is fixed at the upper end of the locking screw 2, and a rotating handle 21 is fixed at the upper end of the pressing block 22. By rotating the rotating handle 21, the locking screw 2 is screwed so that the pressing block 22 presses down on the cover 3.

[0030] As Figure 4 shown, the support frame 5 includes a fixing plate 51. On the side of the fixing plate 51 facing the switch body 4, a plurality of uniformly distributed support columns 52 are fixed. The fixing plate 51 and the support columns 52 are integrally formed rubber products. The fixing plate 51 fixes the support columns 52, and the plurality of support columns 52 suspend and support the switch body 4 to facilitate air circulation. At the same time, the support columns 52 made of rubber elastically press the switch body 4.

[0031] As Figure 5 shown, a first installation groove 14 is opened at the inner bottom of the outer shell 1 for fixedly clamping the lower support frame 5, and connecting plates 13 are fixed at the upper positions near the left and right sides of the outer shell 1 for threaded connection with the locking screws 2.

[0032] In this embodiment, the lower support frame 5 suspends and holds up the switch body 4, while the upper support frame 5 presses on the upper side of the switch body 4. At this time, the installation cover 3 is installed and the support frame 5 is squeezed under the pressing of the locking screw 2, so that the upper and lower support frames 5 suspend and clamp the switch body 4 inside the housing 1. When the housing 1 is collided, the support column 52 on the support frame 5 performs elastic buffering to complete the anti-seismic protection of the switch body 4.

[0033] The above is the preferred embodiment of the present utility model. Those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiment. Therefore, the present utility model is not limited to the above specific embodiments, and any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present utility model all fall within the protection scope of the present utility model.
