Abstract
The utility model relates to a wave detector for marshes, which is provided with a casing body, a top cover, a core body of the wave detector, a transmission cable, and a tail cone, wherein, the core body of the wave detector is fixed in the casing body, and the tail cone is fixed under a base of the casing body. The upper part of the core body of the wave detector is also provided with a wire winding frame, a seal gasket, and a fixing ring. A cable wire penetrates through the wire winding frame and the seal gasket, and the contacts of the cable wire are arranged in a sealing cavity of the casing body. The wave detector, the contacts between the core body of the wave detector and the cable wire, and the fixation of the cable wire are all arranged in one casing body. The utility model has the advantages of simple structure, reliable connection, high tensile strength, favorable sealing performance, and low cost. The utility model is an ideal wave detector for marshes.
Description
The utility model relates to a kind of earthquake detector arrangement, specifically a kind of marsh wave detector.
We know, oil, when coal industry carries out geologic prospecting, seismoreceiver is indispensable instrument, have land with wave detector, under water with wave detector, marsh with wave detector or the like.Its many forms with the combination string are applied.Existing marsh geophone combination string generally is made up of wave detector, protective case, threeway, cable enters threeway inside by three terminations of threeway respectively, be connected on the weld holder of threeway inside, wave detector protective case set of systems synthesized various forms of combination strings by threeway.This version is because protective case system and threeway all need sealing, and between cable and the protective case system, need to have good tensile property between cable and the threeway, makes combination string structure complexity, installs and bothers cost height, constructional difficulties.Receiver pattern string problem such as still occur easily leaking, come off between the cable influences operate as normal during use.
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure compact, rationally, and sealing is reliable, and assembling is easy, good manufacturability, marsh wave detector that cost is low.
For achieving the above object, a kind of marsh of the utility model wave detector, it is provided with housing, top cover, detector core body, transmission cable, tail cone, detector core body is fixed in the housing, tail cone is fixed on below the housing base, housing is provided with the cable through hole, it is characterized in that detector core body top also is provided with dish coil holder, sealing gasket, set collar in the housing, sealing gasket bottom set collar inner chamber forms cable contact annular seal space, cable passes dish coil holder and sealing gasket, and its contact is sealed in the housing seal chamber.
The utility model dish coil holder is provided with several serpentine cable through holes, and it plays fastening cable.
The utility model is owing to adopt said structure, and the fixing of the contact between detector core body, detector core body and the cable, cable all places in the housing, saved traditional threeway, cost is reduced, simple in structure, connect reliably, increased the reliability of sealing simultaneously.Coil the tensile strength that has improved between the cable that is provided with of coil holder.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
As can be seen from Figure 1, a kind of marsh of the utility model wave detector, it is provided with housing 7, top cover 1, detector core body 6, transmission cable 2, tail cone 8, detector core body 6 is fixed in the housing 7, tail cone 8 is fixed on below the housing base, housing is provided with the cable through hole, and above-mentioned composition structure and annexation and prior art are basic identical, is not describing in detail.
Characteristics of the present utility model are that detector core body 6 tops also are provided with dish coil holder 3, sealing gasket 4, set collar 5 in the housing, and detector core body 6 is fixing by top cover 1 extruding by above-mentioned each parts.Sealing gasket 4 bottom set collars 5 inner chambers form cable contact annular seal space 9, and cable passes dish coil holder 3 and sealing gasket 4, and its contact is sealed in the housing seal chamber 9.The concrete connection of cable is carried out as required.
The utility model dish coil holder is provided with several serpentine cable through holes, and it plays fastening cable.Cable 2 passes the cable through hole on the housing, passes the serpentine through hole of dish on the coil holder 3 again, passes from the other end, then passes sealing gasket 4, cable and detector core body be connected and cable between tie point be arranged in the annular seal space 9 of housing.
The fixing of contact between the utility model detector core body, detector core body and the cable, cable all places in the housing, saved traditional threeway, and cost is reduced, and increased the reliability of sealing simultaneously.Cable has been fixed in the setting of dish coil holder preferably, has improved the tensile strength between the cable.The utility model is simple in structure, connection is reliable, good airproof performance, cost are low, is a kind of desirable marsh wave detector, is suitable for the connection of various receiver pattern strings.
Claims (2)
1, a kind of marsh wave detector, it is provided with housing, top cover, detector core body, transmission cable, tail cone, detector core body is fixed in the housing, tail cone is fixed on below the housing base, housing is provided with the cable through hole, it is characterized in that detector core body top also is provided with dish coil holder, sealing gasket, set collar in the housing, and sealing gasket bottom set collar inner chamber forms cable contact annular seal space, cable passes dish coil holder and sealing gasket, and its contact is sealed in the housing seal chamber.
