Description

Technical Field

[0001] This utility model relates to the field of broadcast substation technology, specifically to an intrinsically safe broadcast communication substation for mining applications. Background Technology

[0002] A mine-use intrinsically safe broadcasting substation is a communication device specifically designed for use in coal mines or other mining environments. This device is designed to meet intrinsically safe standards, meaning that under normal operating conditions and specified fault conditions, any electrical sparks or thermal effects generated cannot ignite the specified explosive gases, ensuring safety in flammable and explosive environments.

[0003] The main body of a broadcast communication substation is its casing, which is usually equipped with ventilation holes to dissipate heat inside the substation. However, the high dust levels in mines allow dust to easily enter the casing through the ventilation holes, affecting the operation of the communication substation and causing malfunctions. Currently, communication substations lack adequate dustproof components and cannot quickly handle dust or replace filters, resulting in certain defects and deficiencies that require improvement.

[0025] Example

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present invention proposes a mine-use intrinsically safe broadcast communication substation, including a housing 1 with a communication interface 4 on one side, a ventilation hole 3 on one side of the housing 1, and a dustproof component 2 on the side of the housing 1 with the ventilation hole 3. The dustproof component 2 includes: a protective cylinder 201, fixedly connected to the outer wall of the housing 1; a sealing plate 203, adapted to the corresponding cavity 202 of the protective cylinder 201, and two clamping seats 204 fixedly connected to one side of the sealing plate 203, a filter plate 205 is arranged between the two clamping seats 204, the filter plate 205 is adapted to the inner side of the protective cylinder 201; and a locking mechanism 208, fixed to the protective cylinder 201.

[0027] It should be noted that the ventilation hole 3 enables ventilation of the shell 1. By setting a dustproof component 2 on one side of the shell 1 located at the ventilation hole 3, dust protection of the shell 1 can be achieved, preventing dust from the mine from entering the shell 1. The main body of the dustproof component 2 is a protective cylinder 201. By setting a cavity 202 on the protective cylinder 201, the sealing plate 203 can be adapted to the cavity 202 of the protective cylinder 201. By fixing a clamping seat 204 on one side of the sealing plate 203, the filter plate 205 can be clamped between the two clamping seats 204, realizing the assembly and fixation of the filter plate 205. The outline of the filter plate 205 is adapted to the inner wall of the protective cylinder 201, thereby achieving dust protection. By setting a locking mechanism 208 on the protective cylinder 201, the sealing plate 203 can be locked and positioned, controlling the placement and removal of the sealing plate 203 and the filter plate 205, thereby facilitating the replacement of the filter plate 205.

[0028] like Figure 2 As shown, in some embodiments, a control handle 206 is fixedly connected to one side of the sealing plate 203, and a positioning hole 207 is provided on the control handle 206.

[0029] It should be noted that by fixing the control handle 206 on one side of the sealing plate 203, it is convenient to control the placement and removal of the sealing plate 203. By opening the positioning hole 207 on the control handle 206, it is convenient to lock and fix the control handle 206, thereby controlling the locking state of the sealing plate 203 and the filter plate 205, and realizing the control of the replacement of the filter plate 205.

[0030] like Figure 2 and Figure 3 As shown, in some embodiments, the locking mechanism 208 includes a support 2081, which is fixedly connected to the protective cylinder 201; a locking rod 2084, which is slidably connected to the support 2081, and one end of the locking rod 2084 is integrally formed with an arc-shaped protrusion 2085, which is adapted to the positioning hole 207; a protective cap 2083, which is fixedly connected to the other end of the locking rod 2084; and a tension spring 2082, which is sleeved on the locking rod 2084, and both ends of the tension spring 2082 are respectively connected and fixed to the support 2081 and the protective cap 2083.

[0031] It should be noted that the locking mechanism 208 cooperates with the positioning hole 207 on the control handle 206 to control the locking state of the sealing plate 203. The locking mechanism 208 consists of a support 2081, a tension spring 2082, a protective cap 2083, and a locking rod 2084. The locking rod 2084 can move under the action of the tension spring 2082 and close to the positioning hole 207 of the control handle 206 to lock and fix the sealing plate 203. When the locking rod 2084 leaves the positioning hole 207 of the control handle 206, the sealing plate 203 can be removed, and the filter plate 205 can be removed and replaced.

[0032] like Figure 2 and Figure 4 As shown, in some embodiments, a pretreatment mechanism 209 for treating dust is provided on one side of the protective cylinder 201. The pretreatment mechanism 209 includes an annular body 2091, which is fixedly connected to the inner wall of the protective cylinder 201; and multiple grid plates 2092, which are fixed to the inner wall of the annular body 2091 at equal intervals. The grid plates 2092 are inclined, and a dust-absorbing cotton 2093 is provided on one side of each grid plate 2092.

[0033] It should be noted that external gas can enter the housing 1 through the internal area of ​​the annular body 2091. The grid plates 2092 are arranged at equal intervals, and the dust-absorbing cotton 2093 is glued to one side of the grid plate 2092. When the air comes into contact with the dust-absorbing cotton 2093, the dust can be adsorbed on the dust-absorbing cotton 2093, achieving the purpose of initial dust prevention. The dust-absorbing cotton 2093 is fixed to the grid plate 2092 by adhesive, which facilitates the replacement of the dust-absorbing cotton 2093.

[0034] like Figure 2 As shown, in some embodiments, the cavity 202 and the sealing plate 203 are both semi-annular designs, which facilitates the assembly and adaptation of the sealing plate 203 and the filter plate 205, so that the filter plate 205 can be quickly closed inside the protective cylinder 201.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
