Background technology
In mine stope production process, the fragmentation of various geologic anomaly bodies such as tomography, karst collapse col umn, fold, Coal Seam Thickness Change and coal rock layer etc. often have a negative impact to stope ordinary production and Safety Control of Roof; Use electromagnetic wave and cheat technology, can be qualitative to sxemiquantitative detect, analyze various structures, and in order to the safety in production of guiding work face; The tunnel radio wave penetration method is called for short the saturating method in hole.
When electromagnetic wave is propagated in subterranean strata, because moving different of the electrical resistivity p of various rocks, ore and dielectric constant, they absorb different to electromagnetic wave energy, the low-resistance rock stratum has stronger absorption to electromagnetic wave, when wavefront advances direction and runs into the interface that rift structure occurs, electromagnetic wave will produce reflection and refraction action at the interface, also cause the loss of energy, cause the electromagnetic wave signal that receives in the tunnel very faint even do not receive transmission signal, it is unusual to form so-called transmission; Research coal seam, exploiting field, various structure and geologic body are unusual to the various radio wave perspectives that electromagnetic influence causes, thereby carry out the geology deduction and explain the basic principle of the saturating method in hole that Here it is.
It is big inadequately to receive the signal strength signal intensity that the radio signal from transmitter receives with general in the market loop aerial, and receiving ability is poor, and tuning difficulty is installed difficulty; The structure heaviness, the frequent conductively-closed of signal, material and the structural design of employing all do not meet " GB3836-2010 the 4th part explosive atmosphere is by the equipment of essential safe type " i " protection " requirement.
The utility model content
The purpose of this utility model is to provide that a kind of can to satisfy the signal strength signal intensity that radio signal receives big, receiving ability is strong, install simple, be coated with fluid sealant, realize hermetically sealed and waterproof, prevent that electromagnetic wave signal from being masked by steel pipe, and meet the mining radio wave penetration system signal reception loop aerial that the peace mark requires.
For realizing that the technical scheme that the purpose of this utility model adopts is: a kind of mining radio wave penetration system signal receives uses loop aerial, comprising: antenna casing, multiturn coil and antenna base; It is characterized in that: described antenna casing is wrapped in multiturn coil, and antenna casing and multiturn coil are connected on the antenna base; Described antenna base adopts the nylon terminal box.
The interface of described nylon terminal box is to adopt the angle groove, is provided with location hole.
The inside of described nylon terminal box is equipped with the circuit board that resonant capacitance is installed.
Described antenna casing adopts non-closed loop stainless steel round tube, and described stainless steel annular pipe adopts interconnecting of steady pin and nylon terminal box steady pin trepanning fixing.
Described stainless steel annular Guan Weifei closed loop adopts stainless steel, and extended distance is 20mm-150mm.
The diameter of described antenna is 0.5m-0.6m.
The utlity model has following advantage: the utility model adopts this design can effectively increase the reception signal, simultaneously the stainless steel opening is connected with the nylon terminal box, and the shielding of the signal of avoiding, and meet the requirement of peace mark; Adopt the design of angle and location hole can make the installation of product simple, realize hermetically sealed and waterproof effect; Under the condition that satisfies coil optimum resonance, the number of turn is more many, and the receiving ability of antenna is more strong, and simultaneously when satisfying coil optimum resonance and construction under the condition easy to carry, diameter is more big, and receiving ability is more strong.
