Abstract

The present invention relates to an essential safety explosion protection antenna casing of an explosion protection geological radar, which is composed of an upper cover and a base, wherein the upper cover is provided with a cell box and a power supply interface; the upper cover is fixed with the base by rivets; the interface is boned by a sealing adhesive, and the inner part of the casing is completely isolated with outside; the bottom surface of the base uses a concave-convex model to strengthen the compression resistance and beating strength of the whole casing. The present invention can be used as a single placing type antenna, and can also be used as a double-placing type antenna. The double-placing type antenna is connected by screws of a side baffle plate. In the antenna casing, a cell is fixed in the inner part of the casing, and an antenna circuit board in the casing can be directly supplied with power. The present invention is suitable for ground environment, and is likewise suitable for severe environment of gas and coal dust.

Description

Explosion-resistant antenna casing for geological radar

1, the technical field geological radar is a kind of high-resolution subsurface investigation and the non-destructive detecting device that just grows up nearly more than ten years, and explosion-resistant antenna casing for geological radar is a shell of placing geological radar antenna.Departments such as explosion-resistant antenna casing for geological radar can be in the colliery, railway, highway, water conservancy use.Have characteristics such as resistance to compression, anti-collision, explosion-proof, dustproof, protection against the tide, can under adverse circumstances, guarantee the antenna operate as normal.

2, the background technology antenna is geological radar " transducer ", and it is launching electromagnetic wave both, receives electromagnetic wave again.Antenna volume accounts for about 80% of complete equipment volume, and antenna casing directly determines antenna inner core and open-air adaptive capacity, convenience, even has influence on its scope of application.From the beginning of the eighties, China begins to introduce geological radar.The domestic overseas equipment that is using mainly contains at present: the RAMAC series that the YL series that the Pulse EKKO series that SIR series produced in USA, Canada produce, Japan produce, Sweden produce.Having of domestic-developed and use: the highway detection special radar set of the underground geological radar of Chongqing coal science research institute exploitation, the exploitation of ADEL company, the dual-purpose geological radar in integrated water route that Chinese Academy of Sciences's Guangzhou geochemical investigation is developed.In use all there is following shortcoming in the shell of above-mentioned radar antenna: (1) can not use under mine, mainly is not have explosion prevention function; (2) power supply is external, and electric power system does not have and shell forms an integral body; (3) accessory of antenna looses, and integration is poor; (4) antenna volume is big, the operation of improper adverse circumstances.

3, summary of the invention the present invention has realized the explosion prevention function of radar antenna, mainly antenna is placed on explosion-resistant enclosure inside, portion's power supply in the enclosure simultaneously, and, avoided the direct interference of internal electric source to antenna by the screened shielded antanna device.The present invention compares with existing geological radar antenna shell following effective effect: (1) installs skid at base, has avoided the direct friction of antenna casing bottom with ground, has prolonged the useful life of shell; (2) base end face is designed to uneven, has strengthened housing compression strength; (3) loam cake and base are fixed by rivet at vertical bonding strip of loam cake and base side shield place, use fluid sealant to be bonded together, and make whole casing body one integrated mass, have strengthened the resistance to compression and the anti-collision ability of whole housing; (4) whole enclosure interior is as the casing that is isolated from the outside, can be under extraneous adverse circumstances operate as normal; (5) battery is built in enclosure interior, has made things convenient for on-the-spot real work; (6) the swash plate shape is made on the vertical limit of loam cake, promptly reduces volume, has strengthened compression strength again; (7) design volume reduces, and has strengthened the ability of the different external environments of antenna adaptation; (8) the present invention can be used as the formula of singly putting (sending and receiving one) use, also can be used as two formulas (transmitting-receiving separately) of putting and uses.

4, the overall structure schematic diagram of description of drawings explosion-resistant antenna casing for geological radar as shown in Figure 1, it is made up of loam cake (I) and base (II), (III) is the potted line of loam cake and base.The explosion-resistant antenna casing upper cover top view as shown in Figure 2, on Fig. 2 as seen: left and right sides battery case (6) (6 '), left and right sides battery case sealing gasket (7) (7 '), left and right sides handle (19) (19 '), last lid top panel (3), loam cake limit platform (4), control circuit board plate socket (1), wiring board sealing strip (2), loam cake slanting baffle (5).The vertical end view of loam cake as shown in Figure 3, on Fig. 3 as seen: loam cake slanting baffle (5), longitudinal side are to baffle plate (8), and loam cake vertically glueds joint bar (9), left and right sides battery case (6) (6 ').The loam cake transverse side view as shown in Figure 4, on Fig. 4 as seen: the horizontal side board of loam cake (10), battery case (6), loam cake laterally glued joint bar (11).The base upward view as shown in Figure 5, on Fig. 5 as seen: base slanting baffle (15), concave bottom plate (17) and sunken bottom plate (16).The vertical end view of base as shown in Figure 6, on Fig. 6 as seen: rivet (18), base longitudinal side baffle plate (12), base slanting baffle (13).The base transverse side view as shown in Figure 7.On Fig. 7 as seen: rivet (18), screw (20), skid (19), the horizontal side board of base (14).Battery case of the present invention can be opened the replacing battery at any time.Can change control circuit board at any time by the control circuit board socket.Entire antenna comes shell to become handshaking with external circuits by the control circuit board socket.

5, the embodiment specific embodiment of the invention is as follows: the loam cake of (1) explosion-resistant antenna casing for geological radar and base use good insulation preformance, resistance to wear good, and the material of certain intensity is arranged---as high-strength polyethylene by injection molded; (2) loam cake and base are fixed by rivet, and fluid sealant is bonding; (3) select the big dry sheet material of good insulating, intensity as side board at the medial surface of housing; (4) skid selects for use wear-resisting material to become strip, and two upwarps into arcuation,, can load and unload at any time in the horizontal side of antenna casing by screw; (5) battery and control circuit are hedged off from the outer world by sealing gasket, and the wiring board power supply obtains from the battery of enclosure interior.
