Description

Butt joint device for underground measuring and adjusting device and water distributor
Technical Field
The invention relates to a docking mechanism applied to the technical field of underground docking measurement and adjustment.
Background
Currently, each oil field well needs to adopt an underground measuring and adjusting instrument to adjust the injection amount of water distributors of each layer. During adjustment, the underground measuring and adjusting instrument is firstly in butt joint with a water distributor in a well, then the water distributor is adjusted, and the water injection amount of each layer is controlled. The existing butt joint mode and the driving mode of the measuring and regulating instrument and the water distributor are complex, and the problem is an important problem needing to be improved in the prior art. The traditional docking mode has certain limitations, and the following problems exist in the traditional instrument: the driving movement mode of the butt joint device is troublesome and complex, the structure of the butt joint device is not simple and understandable, and meanwhile, when some parts break down, the butt joint device cannot be retracted, so that the butt joint device is blocked with a water distributor and cannot move.
Disclosure of Invention
In order to solve the technical problems mentioned in the background art, the invention provides a docking device for a downhole modulator and a water distributor, which can be retracted through manual operation of a user, and has a simple docking structure and a simple driving mode and is easy to operate.
The technical scheme of the invention is as follows: the butt joint device for the underground measuring and adjusting device and the water distributor comprises a left butt joint claw, a right butt joint claw, a U-shaped spring, a claw seat, a claw outer sleeve rear cover, a claw outer sleeve front cover, a cam shaft and a motor.
U-shaped springs are arranged in the inner grooves of the butt-joint claws, and the U-shaped springs are connected with the left butt-joint claw and the right butt-joint claw through claw holes by spring cylindrical pins; the left side and the right side of the upper end of the claw seat are connected with the inner through holes of the left butt-joint claw and the right butt-joint claw through claw seat cylindrical pins, so that the left butt-joint claw and the right butt-joint claw can rotate for a certain angle on the plane where the claw seat is located.
The lower ends of the butt-joint claws of the left butt-joint claw and the right butt-joint claw are both of inclined surface structures.
The peripheries of the claw outer sleeve rear cover and the claw outer sleeve front cover are fixedly connected through four cover screw threads to form an internal cabin, the left butt joint claw and the right butt joint claw and the claw seat are located in the internal cabin, and cover seat screws penetrate through the rear cover hole and the claw seat hole to fix the claw seat in the internal cabin.
The cam shaft penetrates through an inner hole in the claw outer sleeve rear cover and is connected with the cam, and the cam is an elliptic cylinder; the middle of the cam is provided with a cam inner hole, the upper end and the lower end of the cam shaft are identical in structure and arc-shaped, the structural shape of the cam inner hole is identical to that of the lower end of the cam shaft, and the lower end of the cam shaft is inserted into the cam inner hole to realize the fixed connection of the cam inner hole and the cam lower end.
The structural shape of the inner groove of the motor is the same as that of the upper end of the cam shaft, and the upper end of the cam shaft is inserted into the inner groove of the motor to be fixedly connected with the inner groove of the motor, so that the motor, the cam shaft and the cam can rotate synchronously.
The inner sides of the upper ends of the left butt joint claw and the right butt joint claw and the upper end of the claw seat form a left claw inner groove and a right claw inner groove, the cam is located in the left claw inner groove and the right claw inner groove above the claw seat in the inner cabin, the width of the upper end of the left claw inner groove and the width of the upper end of the right claw inner groove change along with the rotation of the cam, and in the rotating process of the cam, the two sides of the cam are always in contact with the upper end.
The invention has the following beneficial effects:
when the invention is used, the ground controller sends control signals through the claw opening button and the claw retracting button and transmits the control signals to the motor, and the motor drives the left butt-jointed claw and the right butt-jointed claw to open and retract. When the left and right butt-joint claws are not opened, the U-shaped springs in the inner grooves of the left and right butt-joint claws are in a compressed state and have elasticity, at the moment, the left end of the cam is in contact with the inner side surface of the left butt-joint claw, the right end of the cam is in contact with the inner side surface of the right butt-joint claw, and the position of the cam at the moment enables the width of the upper end of the inner groove of the left and right claws to reach the maximum length; when the ground controller sends a claw opening signal, the motor drives the cam shaft and the cam to synchronously rotate, and when the cam is to rotate, the contact between the left end of the cam and the inner side surface of the left butt-joint claw and the contact between the right end of the cam and the inner side surface of the right butt-joint claw are to be separated simultaneously. The width of the upper end of the inner grooves of the left claw and the right claw reaches the maximum length, namely the maximum radius length of the oval shape of the cam, and the upper ends of the left claw and the right claw are always in contact with the cam, so that the width of the upper ends of the inner grooves of the left claw and the right claw is continuously reduced along with the rotation of the cam in the cam rotating process, the U-shaped spring is in a compressed state and has elasticity, the lower ends of the left claw and the right claw are outwards opened under the elasticity of the U-shaped spring, in addition, the inner side surface of the left claw is always in contact with the left end of the cam and the inner side surface of the right claw is always in contact with the right end of the cam in the cam rotating process until the cam rotates to enable the width of the upper ends of the inner grooves of; when the ground controller sends a claw receiving signal, the motor drives the cam shaft and the cam to synchronously rotate, at the moment, the cam is about to rotate, the left end of the cam gives a transverse force in the opening direction of the left butt-joint claw to the inner side surface of the left butt-joint claw, the right end of the cam gives a transverse force in the opening direction of the right butt-joint claw to the inner side surface of the right butt-joint claw, under the action of 2 transverse forces, the left butt-joint claw and the right butt-joint claw start to retract and compress the U-shaped spring until the left butt-joint claw and the right butt-joint claw are completely retracted into the inner cabin, and at the moment, the cam rotation is stopped at the position when the.
In conclusion, the butt joint device provided by the invention has the advantages of simple structure, low manufacturing cost, simplicity in operation and almost no loss of the butt joint device in the using process. The driving motion mode of the butt joint claw structure is simple, understandable and unique, the butt joint claws are driven to move through synchronous rotation of the motor, the cam shaft and the cam, and a signal is sent at any time through the ground controller to drive the butt joint claws to open and retract; when the part breaks down and leads to the butt joint claw can't withdraw, unique inclined plane structure can let operating personnel manually carry out the instrument and withdraw the butt joint claw, has prevented to block with the water injection mandrel and can't continue the experiment.
