Description

Collection station shell

Technical Field

The utility model belongs to the technical field of the collection station, especially, relate to a collection station casing.

Background

Currently, seismic surveys employ instrument systems of 408XL and 428XL, and these two acquisition devices have been in use for over a decade since the beginning. With the increase of exploration strength, more and more acquisition equipment is invested, and the receiving of hundreds of channels of the original single cannon is increased to the receiving of tens of thousands of channels of the existing single cannon. After the equipment is used for a long time, the acquisition equipment is continuously aged, the maintenance times of the acquisition station are relatively increased, and the more maintenance times, the higher the frequency of the acquisition station to be dismounted from the data transmission cable is. From 408XL collection station and 428XL collection station that use at present maintenance, the not good condition of seal situation is more and more between the wiring board on the data transmission cable and the collection station casing, the water-proof effects of collection station in carrying out field construction in-process is also more and more poor, get into collection station inside through not sealing up the gap when rainwater or dew, will corrode collection station circuit board original paper, give birth to the halogen rust, make its collection station work unstable, the index can't reach the qualification state, serious will make collection station unable the restoration and scrap, the accuracy of field construction efficiency and seismic data collection has seriously been influenced, make its manufacturing cost greatly increased.

How to solve the problem that the collection station can not work normally because of the water inflow of the collection station due to rain and dew or pond ditches in field construction becomes a problem to be continuously solved by the collection station.

From the 408XL and 428XL collection stations currently in use, the main reasons for water ingress in a collection station are as follows:

1. and a sealing ring is not arranged between the shell and the cable wiring board, and a sealing ring groove is not coated with waterproof grease.

2. The fastening screw between the shell and the cable wiring board is not installed in place or not installed in place;

3. the shell of the acquisition station and the wiring board on the cable wire cannot be fastened due to the hole sliding buckle, and the sealing effect cannot be achieved.

The 1 st and 2 nd reasons can artificially achieve the purpose of making the most of the responsibility, and the maintenance work attitude is serious and can be solved. The reason for the No. 3 is mainly caused by the fact that the fastening screw and the screw hole of the shell of the collecting station slide to cause that the connecting line plate and the shell of the collecting station cannot be fastened.

The problem of slipknot between screw and the screw is promptly analyzed to the unable fastening reason of gathering station metal screw and plastic housing. After long-term experience accumulation and experimental analysis, the following results are obtained: the reason for the slider is as follows:

1. the structure plastic products of collection station casing, what the connecting plate on casing and the cable conductor adopted is that stainless steel screw connects, among the prior art, in eight screw holes through eight stainless steel screws wrench-in casing to reach fastening cable conductor connecting plate and the sealed effect of collection station casing. The effect is very poor by only relying on stainless steel screws for sealing.

2. The collection equipment will remove the bad and non-qualified 408 or 428 collection stations from the cable patch panel during inspection and maintenance and then reinstall the qualified collection stations on the data transfer cable patch panel.

In order to save the labor of manually dismounting eight screws and improve the maintenance efficiency for maintenance personnel, a commonly adopted electric wrench is used for dismounting screws. The electric wrenches of the original squad are different in model and brand, and the torque power designed by the electric wrenches is relatively different, so that gears marked on the electric wrenches are all provided with multiple gears such as 1, 2, 3 and 4, but the electric wrenches produced by various manufacturers have gears, but the power and the torque output by the same gear are different. The instrument is in the use, and maintenance person differs to electric wrench's control strength, consequently when carrying out many times dismantlement screw to its collection station, is difficult to avoid giving the destruction because the too big screw hole's on will gathering the station casing screw of moment. The collection station is unloaded to turn round (fastening torsion 1Nm (Nm) +/-20% @ 600 rpm), along with equipment life cycle's continuous extension, the corresponding continuous increase of maintenance's number of times, it is more frequent to unload the collection station frequency of going on installing again from the cable wire, make collection station casing screw hole smooth silk more serious, and more, there is the screw hole's on the collection station casing screw thread just not at all, it can't reach encapsulated situation to make collection station casing and cable junction board, make its casing scrap and can't continue to use, thereby the collection station casing that must only renew.

For this reason, in the prior art, the following solutions are adopted:

1. if two screw holes are found on the shell of the collecting station to be screwed, a small section of single copper wire is simply adopted and clamped in the screw hole of the sliding buckle to be filled, and then a stainless steel metal fixing screw is twisted.

The method can only play a certain fastening role in a short time, and once the equipment is moved to the vibration of getting on or off the bus or is carried for a long time, the screw will loosen, so that the fastening role cannot be played. The circuit cover plate on the cable conductor will have a gap with the shell. The waterproof function is lost. Particularly, in summer, the collection equipment is exposed to the sun and suddenly encounters rainstorm or plum rain, so that the collection equipment is unqualified in large area, has electric leakage and is dead, frequent line breakage occurs in the whole arrangement, collection chains are continuously replaced, the construction progress is delayed, and the cost of a construction team is correspondingly increased.

2. Firstly, the new shell of the acquisition station is compared with the slide fastener shell for measurement: the diameter of the screw hole of the shell of the new acquisition station is found to be 4mm, and when the stainless steel screw is screwed into the hole of the shell of the acquisition station from the top, the stainless steel screw enters the hole through self tapping of the original acquisition station, so that the cover plate is tightly connected with the shell. The screw size of the stainless steel metal screw is measured to be about 2mm, the thread diameter is 4mm, and the thread pitch is 2 mm.

Scheme 1, the thread diameter of the screw is increased to 4.5mm, namely the stainless steel screw is replaced.

If the first self-tapping stainless steel screw is directly used, two different screws are invisibly generated on the same equipment, the cost is increased, and meanwhile, the first self-tapping stainless steel screw is wrongly screwed into the unsliding screw hole due to human error, so that a good screw hole is invisibly enlarged; if the slide fastener appears again, the diameter of the screw must be increased continuously, so that the aperture of the shell of the collection station is larger and cannot be expanded, and finally the shell is scrapped. This method excludes this.

Scheme 2:

various colloidal glues are filled into the holes of the slide fastener, and the problem of screwing at the time can only be solved when the holes are punched and the screws are screwed.

Scheme 3:

the flange type sleeve with the same diameter as the hole is added with strong glue to be embedded into the slide fastener hole, and after tests, the torque of the electric wrench is slightly larger, the sleeve immediately rotates with the screw, and cannot be fixed.

Therefore, how to solve the above-mentioned drawbacks of the prior art becomes the direction of efforts of those skilled in the art.
