Description
Technical Field
[0001] The utility model relates to the technical field of signal base stations, in particular to a intrinsically safe base station for mines. Background Technique
[0002] The intrinsically safe base station is a communication device designed specifically for flammable and explosive environments such as coal mines. It has explosion-proof characteristics and can provide communication services while ensuring safety. The popularization and application of the intrinsically safe base station are of great significance for improving the communication quality and safety in special environments such as mines.
[0003] For the current intrinsically safe base, there is an important operating specification during operation, which prohibits staff from opening the cover and operating while the power is on to avoid generating electric sparks in the mine tunnel. However, due to the actual distance of the power switch, the reasons of the staff themselves, etc., there are still some staff who violate the regulations, posing certain potential safety hazards. Content of the Utility Model
[0004] The purpose of the utility model is to provide an intrinsically safe base station for mines to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution:
[0006] An intrinsically safe base station for mines includes a base station main body. At both ends of the upper surface of the base station main body, enhanced antennas are movably installed. At the four side edges of the front opening of the base station main body, electromagnetic lock catches are buried and installed. The base station main body includes a base station housing. At the edge of the front opening of the base station housing, a cover clamping groove is opened. A cover clamping edge is clamped at the cover clamping groove. The cover clamping edge is fixedly installed on the rear surface of the base station cover. The electromagnetic lock catch includes a lock catch sliding groove. A lock catch main body is slidably installed in the lock catch sliding groove. A metal sheet is embedded in the middle of the lock catch main body. An electromagnet is embedded at a position corresponding to the metal sheet in the lock catch sliding groove.
[0007] Furthermore: At the four corners of the rear surface of the base station housing, installation screw plates are fixedly installed. At both ends of the upper surface of the base station housing, antenna storage grooves are opened. In the middle of the upper surface of the base station housing, a lifting handle is fixedly installed.
[0008] Furthermore: A number of groups of external connection channels are fixedly inserted and installed on both sides of the base station housing. At one end side surface of the external connection channel, a screw sleeve sliding groove is opened. A sliding screw sleeve is slidably sleeved in the screw sleeve sliding groove. The inner side of the sliding screw sleeve is screwed with a connecting screw port. The connecting screw port is fixedly installed at one end of a wire pipe.
[0009] Furthermore, the enhanced antenna includes a hinged end, on the upper side of which an antenna body is fixedly installed. Four blade storage grooves are equiangularly formed in a circular shape on the side surface of the antenna body. The upper end, lower end and middle of the blade storage groove are all provided with sliding sleeve storage grooves. A telescopic sliding sleeve is slidably clamped in the sliding sleeve storage groove. One end of the telescopic sliding sleeve is slidably sleeved with one end of a telescopic sliding rod, and the other end of the telescopic sliding rod is slidably sleeved with a sliding rod storage groove. The sliding rod storage groove is formed at the upper end, lower end and middle of the inner side surface of the extended blade.
[0010] Furthermore, return springs are fixedly installed between both ends of the latch body and the latch chute.
[0011] Furthermore, the hinged end is hinged to one end of the antenna storage groove.
[0012] Furthermore, the latch chute is formed inside the four side surfaces of the cover card slot.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. The cover card edge and the cover card slot are mutually clamped. The base station cover is installed at the front opening of the base station housing. At the same time, the electromagnet is energized to generate a magnetic force to adsorb the metal sheet. Then, the latch body slides in the latch chute, and both ends of the latch body are buckled into the inner wall of the cover card edge to lock the cover card edge and the base station cover, so that the base station housing and the base station cover can be relatively fixedly connected. The traditional bolt structure for fixing the base station cover is abandoned. At the same time, the electromagnet is directly connected to the power supply of the entire base station, so that the base station cover can only be opened when the entire base station is completely powered off, completely eliminating the risk of the base station cover being opened by staff's illegal operation with electricity.
[0015] 2. In some special mine tunnels, such as iron ore mines with a relatively high iron content, when a structure similar to a Faraday cage is formed in the mine tunnel and the signal is suppressed, the folded enhanced antenna is pulled out from the antenna storage groove, and each extended blade is pulled out from the sliding rod storage groove. The telescopic sliding sleeve and telescopic sliding rod in the extended state are used to maintain the support connection of the antenna body to the extended blade, so as to enhance the signal transceiver ability of the base station.

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a mine intrinsically safe base station includes a base station main body 1. An enhanced antenna 2 is movably installed at both ends of the upper surface of the base station main body 1. An electromagnetic lock 3 is buried and installed at the four side edges of the front opening of the base station main body 1. The base station main body 1 includes a base station housing 101. A cover clamping groove 105 is provided at the edge of the front opening of the base station housing 101. A cover clamping edge 106 is clamped at the cover clamping groove 105. The cover clamping edge 106 is fixedly installed on the rear surface of the base station cover 107. The electromagnetic lock 3 includes a locking chute 301. A locking body 302 is slidably installed in the locking chute 301. A metal sheet 303 is embedded in the middle of the locking body 302. An electromagnet 304 is embedded at a position corresponding to the metal sheet 303 in the locking chute 301; Return springs 305 are fixedly installed between both ends of the locking body 302 and the locking chute 301; The locking chute 301 is provided inside the four side surfaces of the cover clamping groove 105.
[0024] Specifically, the cover card edge 106 and the cover card slot 105 are engaged with each other, and the base station cover 107 is installed at the front opening of the base station housing 101. At the same time, the electromagnet 304 is energized to generate a magnetic force, which adsorbs the metal sheet 303, so that the lock body 302 slides in the lock chute 301, and both ends of the lock body 302 are buckled into the inner wall of the cover card edge 106 to lock the cover card edge 106 and the base station cover 107, enabling the base station housing 101 and the base station cover 107 to be relatively fixedly connected, abandoning the traditional fixing method of bolts for the base station cover 107. At the same time, the electromagnet 304 is directly connected to the power supply of the entire base station, so that the base station cover 107 can only be opened when the entire base station is completely powered off, completely eliminating the risk of the base station cover 107 being opened with electricity due to the illegal operation of the staff.
[0025] Embodiment 1
[0026] As Figure 2 shown, in this embodiment, mounting screw plates 102 are fixedly installed at the four corners of the rear surface of the base station housing 101. Antenna storage grooves 103 are opened at both ends of the upper surface of the base station housing 101, and a lifting handle 104 is fixedly installed in the middle of the upper surface of the base station housing 101.
[0027] In this embodiment, the base station main body 1 can be lifted and moved through the lifting handle 104. During installation, bolts are passed through each mounting screw plate 102 and screwed into the side wall of the mine tunnel for installation.
[0028] As Figure 2-3 shown, in this embodiment, several groups of external channels 108 are fixedly inserted and installed on both sides of the base station housing 101.

[0032] As Figure 1-2, as shown in Fig. 4, in this embodiment, the enhanced antenna 2 includes a hinged end 201. An antenna body 202 is fixedly installed on the upper side of the hinged end 201. Four blade storage grooves 203 are equiangularly formed on the side surface of the antenna body 202 in a circular shape. The upper, lower, and middle parts of the blade storage groove 203 are provided with sliding sleeve storage grooves 204. A telescopic sliding sleeve 205 is slidably clamped in the sliding sleeve storage groove 204. One end of the telescopic sliding sleeve 205 is slidably sleeved with one end of a telescopic sliding rod 206. The other end of the telescopic sliding rod 206 is slidably sleeved with a sliding rod storage groove 207. The sliding rod storage groove 207 is formed at the upper, lower, and middle parts of the inner side surface of the extended blade 208. The hinged end 201 is hinged to one end of the antenna storage groove 103.
[0033] During specific implementation, in some special mine tunnels, such as in iron ore mines with a relatively high iron content, when a structure similar to a Faraday cage is formed in the mine tunnel and the signal is suppressed, the folded enhanced antenna 2 is pulled out from the antenna storage groove 103, and each extended blade 208 is pulled out from the sliding rod storage groove 207. The telescopic sliding sleeve 205 and the telescopic sliding rod 206 in the extended state are used to maintain the support connection of the antenna body 202 to the extended blade 208, so as to enhance the signal transceiver ability of the base station.
