Technical Field

The utility model belongs to the field of inclinometry systems, and relates to the field of single-point inclinometry instrument components for wire coring, in particular to a joint of an inclinometry probe tube and the inclinometry probe tube.

Background

At present, the self-floating type electronic single-point inclinometer and the fixed type electronic single-point inclinometer sold and used in the market can only be suitable for conventional drilling and used in a drill rod with a drill bit or a tray, and the inclinometer is rarely used for drilling and inclinometry in small-bore drilling, especially, the application of the self-floating type electronic single-point inclinometer and the fixed type electronic single-point inclinometer in small-bore rope coring drilling is less, the inner diameter size of the drill bit is large in rope coring, the outer diameter of the drill bit and the outer diameter of the drill rod are in tight contact with a well wall (usually 2 to 4 mm of movable space), so that the inclinometer is easy to exceed the drill bit when the common inclinometer is used for inclinometry in the drilling process, inclination data distortion is caused in sediment inserted into the bottom of the hole, or a small winch of the inclinometer inserted into the sediment cannot be pulled out, the connection position of the top of the inclinometer and a steel wire rope is easy to be clamped at the position of the drill bit when the instrument exceeding the drill bit is lifted, the drill rod cannot enter into an inner annular space to cause upward blockage, drilling accidents are formed or the well inclination exceeds the technical requirements, and the construction difficulty is increased, and even drilling is caused. One of the fatal defects of the rope core drilling technology in China is that the well inclination is too large, the friction resistance between a drill rod in the hole and a side wall is greatly increased, the mechanical rotation speed is reduced, the drill rod is reversely driven, a drill bit cannot effectively contact rock to cause low core taking rate or no core, and even the drill bit is twisted off, so that the drilling is scrapped, the construction period is prolonged, the cost is increased and the like. The primary reason for forming the technical problem is that the inclinometer is immature, so that people cannot well measure the inclination in the drilling process.

Because the inner diameter of the drill bit is large in size, a common single-point inclinometer is easy to pass through the drill bit in the process of lowering, so that certain operation difficulty is brought, the lowering instrument is easy to exceed the drill bit in operation, so that the lowering instrument can not be lifted up in the naked eye at the drill bit to cause an in-hole accident, an operator is required to carefully and carefully judge the length of the lowering steel wire rope, or the defect that the inclinometer can not be used when the lowering steel wire rope is marked when the coring barrel is salvaged is overcome, therefore, a new process and a new method are urgently needed to effectively solve the problem of difficult inclinometry in the process of coring the rope, improve the drilling construction depth and the hole forming rate, finally realize the efficient utilization of coring of the rope, reduce the limitation of coring construction of the rope by the hole and realize the better development of coring of the rope.

Disclosure of Invention

In order to solve the problems, the utility model provides a new technical scheme: the utility model provides a survey probe card connects, includes connecting portion and the joint body of interconnect, and connecting portion are circular barrel, and the joint body is the tubular structure that the tip expands outward.

Further, the outward expansion end part of the clamping connector body is provided with a through groove along the axial direction of the clamping connector body, and the through groove is arranged on the outer surface of the clamping connector body. The resistance of mud is reduced when the mud is lifted and lowered.

Further, a plurality of through holes are formed in the side wall of the clamping connector body, and the directions of the through holes are parallel to the axial direction of the clamping connector body. Can further reduce the resistance of mud during lifting and lowering

Further, the lower end of the clamping connector body is provided with a round angle. Wear is reduced when the inside of the drill bit is in contact.

Further, the connecting part and the clamping connector body are axially connected into a whole.

The lower end of the inclinometer probe tube is connected with the connecting part of the clamping connector.

The utility model has the beneficial effects that (1) the risk of drilling or salvaging the instrument caused by the fact that the inclinometer device is stuck in the naked eye at the drill bit after passing through the drill bit is avoided.

(2) The wire rope that can put down in place when salvaging the core section of thick bamboo does not make the survey that just can be relieved, need not worry to put down the wire rope too much.

(3) The accessory solves the problem that the instrument passes through the drill bit to cause the accident in the hole in the process of inclinometry, improves the success rate and the accuracy of inclinometry, effectively prevents and weakens the bending of the drilled hole, and timely adjusts the corresponding drilling parameters.

(4) The auxiliary time is reduced, the drilling cost is reduced, the service life of the drill rod is prolonged, the consumption of the pipe is reduced, and the like.
