Description

Technical Field

[0001] This utility model relates to the field of communication device technology, and in particular to an explosion-proof antenna for use in oil storage caverns. Background Technology

[0002] With the widespread use of communication and monitoring equipment in the industrial sector, higher requirements have been placed on the monitoring quality in actual use, especially for communication and monitoring equipment products used in hazardous locations with flammable and explosive gas environments and dusty environments. Wireless mobile has become an indispensable part of industry, and ordinary AP devices are widely used. When communication equipment is in a flammable and explosive working environment, it is usually necessary to seal and explosion-proof the communication tools. Traditional explosion-proof antennas include a base and an antenna mounted on the base. The base is equipped with a cover, and the antenna is encased inside the cover. Due to the relatively high resistance of the existing cover, the penetration of electromagnetic waves into the cover is greatly reduced, resulting in a decrease in the signal emitted by the antenna. At the same time, static electricity will be generated on the cover over a long period of time, which greatly increases the significant safety hazard of the antenna in flammable and explosive environments.

[0003] Meanwhile, the internal structure of oil storage caverns is generally different. When using them, the antenna angle needs to be adjusted according to the actual shape and corners of the cavern to achieve full signal coverage inside the cavern. Existing antenna devices have a fixed angle after the antenna base is fixedly installed, which makes it inconvenient for users to adjust the antenna angle according to the actual terrain and makes it difficult to adapt to the signal coverage requirements in complex environments.

A protective sleeve is provided on the outside of the antenna, and epoxy resin is filled between the protective sleeve and the antenna to form an epoxy resin layer. The antenna is mounted on the base. The base includes a mounting plate and two connecting frames. Both connecting frames are located at the bottom of the mounting plate. A rotating shaft is provided between the connecting frames. The rotating shaft is fixedly connected to the connecting frames. The adjustment frame includes two support plates, an adjusting gear, and an adjusting screw. The adjusting gear and the adjusting screw mesh with each other. Both the adjusting gear and the adjusting screw are installed in an adjustment box. The adjustment box is fixed to the side of a support plate. Both support plates have connecting holes on their tops. The rotating shaft passes through the connecting holes and is rotatably connected to the connecting holes. One end of the rotating shaft is fixed to the adjusting gear.

[0006] Furthermore, the antenna has a connection end at its bottom; the connection end has a filling hole; the filling hole is connected to the epoxy resin layer.

[0007] Furthermore, the protective sleeve is provided with multiple heat dissipation holes; the heat dissipation holes pass through the epoxy resin layer and communicate with the antenna surface.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3The diagram shows an explosion-proof antenna for use in an oil storage cavern, comprising an antenna body and an adjustment frame. The antenna body includes a base and an antenna 1. A protective sleeve 3 is provided on the outside of the antenna 1, and epoxy resin is filled between the protective sleeve 3 and the antenna 1 to form an epoxy resin layer 2. The antenna 1 is mounted on the base. The base includes a mounting plate 6 and two connecting frames 7. Both connecting frames 7 are located at the bottom of the mounting plate 6. A rotating shaft 8 is provided between the connecting frames 7. The rotating shaft 8 is fixedly connected to the connecting frames 7. The adjustment frame includes two support plates 9, an adjusting gear 93, and an adjusting screw 92. The adjusting gear 93 meshes with the adjusting screw 92. Both the adjusting gear 93 and the adjusting screw 92 are installed in an adjustment box 91. The adjusting gear 93 meshes with... The adjusting screw 92 is equivalent to a worm gear transmission structure. The meshing point of the two can be positioned by a conventional positioning bolt block, and there is a self-locking function between them. After the angle adjustment is completed, it can be locked automatically for convenient use. The adjusting box 91 is fixed to the side of a support plate. The top of both support plates 9 is provided with a connecting hole 90. The height of the support plate 9 is adjusted according to the length of the mounting plate 6 so that when the mounting plate 6 rotates, the end of the mounting plate 6 is not blocked by the bottom connecting plate 10. This is a conventional adjustment method. The entire antenna 1 can swing at least 90° left and right under the drive of the adjusting gear 93. The rotating shaft 8 passes through the connecting hole 90 and is rotatably connected to the connecting hole 90. One end of the rotating shaft 8 is fixed to the adjusting gear 93.

[0019] The antenna 1 has a connecting end 5 at its bottom; the connecting end 5 has a filling hole 51; the filling hole 51 is connected to the epoxy resin layer 2, and the connecting end 5 is located at the junction of the antenna 1 and the mounting plate 6, through which epoxy resin is poured into the epoxy resin layer 2.

[0020] The protective sleeve 3 is provided with multiple heat dissipation holes 4; the heat dissipation holes 4 pass through the epoxy resin layer 2 and communicate with the surface of the antenna 1. The heat dissipation holes 4 are used to dissipate heat from the antenna 1 and prevent explosion due to uneven heat dissipation of the antenna 1.

[0021] The protective sleeve 3 is made of PMMA or PC material. The protective sleeve 3 is made of explosion-proof material, preferably polymethyl methacrylate (PMMA) or polycarbonate (PC). Both materials have flame-retardant properties and good antistatic effects, making them suitable for explosion-proof locations.

[0022] The adjusting screw 92 is provided with a rotating handle 921 at its end. By rotating the adjusting screw 92 by rotating the handle 921, the adjusting gear 93 is rotated.

[0023] The support plate 9 is fixed on the bottom connecting plate 10; the connecting plate 10 is provided with bolt holes 101, and the connecting plate 10 is fixed to the ground or wall by bolts to realize the fixation of the entire antenna device.

[0024] In use, first fix the connecting plate 10 in the designed position of the antenna, then rotate the rotating handle 921 to drive the adjusting screw 92 and the adjusting gear 93. Under the rotation of the adjusting gear 93, the rotating shaft 8 rotates, and the antenna 1 body fixedly connected to the rotating shaft 8 will rotate synchronously to realize the adjustment of the angle of the antenna 1.
