The outer side of the explosion-proof control box body is connected with a buffer plate through a shock-absorbing spring, and a water tank is installed at the top of the explosion-proof control box body, and a water pump is installed in the water tank. The end of the water pump is connected with a heat dissipation water pipe, and the heat dissipation water pipe is installed on the inner wall of the explosion-proof control box body, and the end of the heat dissipation water pipe is connected to the water tank; the heat dissipation holes are equally spaced at the bottom of the explosion-proof control box body, and the heat dissipation holes and the fan form a ventilation structure; the shock-absorbing spring and the buffer plate form a buffer structure, and the positions of the shock-absorbing spring and the buffer plate correspond one by one; a connecting rod is hinged on the end face of the buffer plate, and the end of the connecting rod is hinged with a slider, and the slider is connected in the vertical groove, and the vertical groove is opened on the outer side wall of the explosion-proof control box body; the slider is made of a permanent magnet, and the polarities between adjacent sliders are opposite, and both the slider and the vertical groove are designed as dovetail-shaped structures; the heat dissipation water pipe is laid in a winding shape on the inner wall of the explosion-proof control box body, and the heat dissipation water pipe forms a water circulation structure through the water tank and the water pump.

[0004] The following deficiencies exist in the above patent:

[0005] 1) The explosion-proof control box body is an integral structure. When the explosion-proof control box body explodes, the explosion-proof control box body bursts open, and there is a risk of debris flying.

[0006] 2) Springs are used for buffering. However, when the explosion-proof control box body explodes, the springs cannot restrict the flying of debris.

[0007] 3) When an explosion occurs in the explosion-proof control body, it will cause the explosion-proof control box body to deform and become unusable. Therefore, the damage frequency after the explosion is high. Utility Model Content

[0008] In view of the problems existing in an existing explosion-proof control box with a temperature detection function, the present utility model is proposed.

[0009] Therefore, the purpose of the present utility model is to provide an explosion-proof control box with a temperature detection function, which solves the problems existing in the above-mentioned patent. The explosion-proof control box body is of an integral structure. When the explosion-proof control box body explodes, the explosion-proof control box body bursts open, and there is a danger of debris flying. The buffer is carried out by a spring. However, when the explosion-proof control box body explodes, the spring cannot limit the flying of debris. When the explosion-proof control body explodes, it will cause the explosion-proof control box body to deform and become unusable. Therefore, the frequency of damage after explosion is high.

DETAILED DESCRIPTION OF THE INVENTION

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The present invention provides an explosion-proof control box with a temperature detection function. Please refer to Figures 1-4, including a control box composed of a rear plate body 1, a left plate body 2 and a right plate body 3. A temperature sensor is installed on the inner wall of the control box. For example, the temperature sensor is installed on the rear plate body 1. The top of the rear plate body 1 is integrally provided with a top plate body 11, and the bottom of the rear plate body 1 is integrally provided with a bottom plate body 12; a door panel 6 is hinged on the top plate body 11 through a hinge 4, and a docking structure is arranged between the door panel 6 and the bottom plate body 12. The docking structure includes a first docking block 61 welded to the bottom end of the door panel 6, and a second docking block 121 is welded to the top end of the bottom plate body 12. Internal threaded holes are opened at the corresponding positions of the first docking block 61 and the second docking block 121, and the first docking block 61 and the second docking block 121 are fixed by bolts;

[0029] The bottom of the left plate body 2 is hinged to the bottom plate body 12 through a pivot, and the bottom of the right plate body 3 is hinged to the bottom plate body 12 through a pivot;

[0030] Thin sheets 111 are arranged on both sides of the bottom of the top plate body 11, and the left plate body 2 and the right plate body 3 are respectively fixed to the two thin sheets 111 through bolts 5.

[0031] An articulated block 122 is welded to the bottom of the bottom plate body 12. The bottom of the left plate body 2 is integrally provided with a first thickening strip 21, and the first thickening strip 21 and the articulated block 122 on the left side of the bottom of the left plate body 2 are hinged through a pivot;

[0032] The bottom of the right plate body 3 is integrally provided with a second thickening strip 31, and the second thickening strip 31 and the articulated block 122 on the right side of the bottom of the left plate body 2 are hinged through a pivot.

[0033] The left plate body 2 and the right plate body 3 have the same thickness, and the thickness of the thin sheet 111 is less than the thickness of the left plate body 2. At this time, the thin sheet 111 is integrally formed or welded to the rear plate body 1. At this time, the connection strength between the tops of the left plate body 2 and the right plate body 3 and the rear plate body 1 is weaker than that of the control box formed on one side.

[0034] During specific use, since the connection strength between the top of the left plate body 2, the top of the right plate body 3 and the rear plate body 1 is weak, when an explosion occurs, the connection between the top of the left plate body 2, the right plate body 3 and the rear plate body 1 will burst first, thereby reducing the probability of the left plate body 2 and the right plate body 3 being blown away.

[0035] Embodiment 2:

[0036] Different from Embodiment 1: The thin sheet 111 is made of plastic. At this time, the connection strength at the joints between the top of the left plate body 2, the right plate body 3 and the rear plate body 1 is relatively weaker, so that the thin sheet 111 is more likely to break, thereby reducing the probability of the left plate body 2 and the right plate body 3 being blown off.

[0037] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way, and the exhaustive description of these combinations is omitted in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
