Abstract

The utility model discloses a portable marsh detector, the shell body of the main body of which is provided with an upper and a lower shell bodies, and the upper and the lower shell bodies are connected with each other through a clamping spring; the space of the junction plane of the upper and the lower shell bodies is provided with a sealing ring; a regulating ring is arranged between the detector arranged in the lower shell body and the welding wire plate arranged in the right cavity of the upper shell body; the cable welded on the welding wire plate penetrates through the upper shell body, a lens-shaped water-proof sleeve, a pressing cap, wire clamp, and a tail sleeve, wherein, the water-proof sleeve is arranged in the left cavity of the upper shell body and closely pressed by the pressing cap; the wire clamp is provided with an outer taper face and matched with a taper hole of the tail sleeve; the wire clamp can be driven to closely clamp the cable by rotating the tail sleeve. The utility model has the advantages of reliable sealing ability and small welding point force bearing, which is suitable for the petroleum exploration in coastal or marshy districts.

Description

Light marsh geophone

The utility model relates to a kind of light marsh geophone.

Current, all use marsh geophone in the petroleum prospecting of coastal and marsh land, shallow sea by external import, the cable of this marsh geophone directly is welded on the solder joint after passing seal, cable tension is born by solder joint entirely in the use, stressed unreasonable, dangerous, structure is complicated, and is whole big and heavy.

The purpose of this utility model is to overcome above-mentioned weak point and the light marsh geophone that can carry out geologic prospecting reliably under wet condition that the three-way connection that designs a kind of main body of being made up of main part such as waterproof jacket that comprises ply-yarn drill, tail cap, lens shaped and upper and lower casing and comprise seal, compact heap and upper and lower casing is formed.

The utility model content:

A kind of light marsh geophone, comprise housing, wave detector, tail nail and sealing, it is characterized in that: the housing of main body is made as, lower house also connects through jump ring, on, be provided with O-ring seal between the faying face of lower house, be loaded on the wave detector in the lower house and be loaded between the bonding wire plate in the right chamber of upper shell and be provided with adjusting ring, the cable that is welded on the bonding wire plate passes upper shell, the waterproof jacket of lens shaped, clamping cap, ply-yarn drill and tail cover are drawn, waterproof jacket is loaded on the left chamber of upper shell and is compressed by clamping cap, ply-yarn drill is provided with male cone (strobilus masculinus) and matches with the taper hole of tail cover, drives the ply-yarn drill clamping cables but rotate the tail cover; The three-way connection that links to each other with the cable of main body is made up of the bonding wire plate of upper and lower casing, compact heap, seal and attached cable line, seal is that the conical surface combines with lower house, compact heap is a stepped appearance, through being threaded, screwing upper shell can clamp cable by compact heap, seal between upper and lower casing; The waterproof jacket two ends all are made as sphere; The upper shell inner end, chamber, a left side and the clamping cap end that match with the waterproof jacket two ends respectively are equipped with inner conical surface; The conical surface of seal is made up of two conical surfaces of different taperings; The upper and lower casing of main body and three-way connection, tail cover, ply-yarn drill are all with the low engineering plastics manufacturing of moisture absorption.

The utility model advantage:

1. owing to the card line mechanism clamping cables of tail cover, ply-yarn drill composition, its resistance to tension reaches more than the 80kg, has increased substantially intensity, has guaranteed wave detector energy operate as normal;

2. owing to be provided with the waterproof jacket and the clamping cap of lens shaped between the upper shell of main body and cable, screw clamping cap, waterproof jacket is squeezed to deform to make radially and obtains sealing with end face, is provided with twice " O " shape O-ring seal in addition between upper and lower casing, forms a reliable sealing system; Three-way connection reaches reliable sealing by compact heap, seal, so the utility model is water-tight under the pressure of 0.1Mpa, insulation resistance can reach more than the 500M Ω;

3. because the body of main body is made as upper and lower casing, be convenient to process and assemble;

4. adjusting ring is the adjustment link of upper and lower casing and wave detector axial dimension, wave detector and housing is connected as a single entity closely, so that seismic signal is accurately spread out of.

5. main body of the present utility model and three-way connection all pass through computing machine and carry out the design of structure and optimized dimensions, so volume is little and have enough characteristics such as intensity.

Fig. 4 is the waterproof jacket cut-open view of lens shaped;

Fig. 5 is a three-way connection seal synoptic diagram.

Further specify the utility model below in conjunction with drawings and Examples.

Please referring to Fig. 1, Fig. 3, light marsh geophone is made up of main body and three-way connection, connects through cable between the two; The lower house of main body is equipped with wave detector 13 for 1 li, the extension line of wave detector is connected on the bonding wire plate 8, the bonding wire plate is loaded in the right chamber of upper shell 2, link together through jump ring 7 between upper and lower casing, between wave detector and bonding wire plate, adjusting ring 12 is housed, adjusting ring is used for adjusting the gap that axial size produces in the upper and lower casing manufacturing, and wave detector and housing are fixed as one.Be provided with support set 9 between upper shell and wave detector end face, establish twice " O " shape O-ring seal 11 up and down between casing joint surface; Be connected in waterproof jacket 6 (Fig. 4), clamping cap 5, ply-yarn drill 4 and the tail cover 3 of cable 14 on the bonding wire plate and draw by upper shell, lens shaped; Rotate clamping cap, the waterproof jacket of pushing lens shaped makes cable and bonding wire plate axially and radially obtain sealing; Rotate the tail cover,, cable is clamped because tail cover and upper shell through being threaded, push ply-yarn drill; Improved cable solder joint stressing conditions, made wave detector be able to operate as normal, the lower house afterbody is equipped with tail nail 10; Compact heap 17, seal 19 that cable of being drawn by main body and cable 18 pass three-way connection (Fig. 2) are connected on the bonding wire plate 20; Upper and

lower casing

16,15 is sleeved on outside compact heap, the seal, upper and lower casing is through being threaded, seal is that the conical surface combines with lower house, seal outside (Fig. 5) is provided with the tapering of 1: 10.5 and 1: 2.625 along total length, when rotating upper shell, compact heap pushing seal is sealed the faying face of cable and seal faying face, upper shell and lower house reliably.In the utility model, wave detector is loaded in the airtight body shell and constitutes a vibration body; The seismic signal that the earth's crust produces is converted into electric signal and can accurately passes to data acquisition system (DAS) by wave detector.
