As shown in fig. 1 to fig. 3, the utility model provides an internal expanding type casing pipe anti-theft oil device, include:

special key 1, special key 1 can be dismantled with lock core 3 and be connected, lock core 3 can be dismantled with lock body 4 and be connected, lock body 4 is equipped with main part 5, be equipped with three outer ejector pin 8 in the main part 5, the distance between the adjacent outer ejector pin 8 equals, clamping ring 6 is connected to the top of outer ejector pin 8, pressure spring 7 is connected to outer ejector pin 8, the jackscrew is constituteed to clamping ring 6, pressure spring 7, outer ejector pin 8, lock body 4 can be dismantled and connect and right cover 2, special key 1, lock core 3, lock body 4 constitute theftproof oil lock jointly.

In practical application, the oil theft preventing device is provided with a matched wrench, namely an auxiliary tool specially applied to connection of the oil theft preventing device.

In the oil theft preventing device, a special key 1 is connected with a lock cylinder 3 through a matched wrench, and the special key 1 is in reverse-buckling connection with the lock cylinder 3; the lock core 3 is connected with the lock body 4 through a matched wrench, and the lock core 3 is in right-handed connection with the lock body 4.

In practical application, the centering sleeve 2 is used for fixing the whole anti-theft oil lock, and the centering sleeve 2 is connected with the lock body 4 through threads.

In the oil theft preventing device, three sets of jackscrews are arranged on a lock body 4, and each jackscrew consists of a pressing ring 6, a pressure spring 7 and an outer ejector rod 8.

It should be noted that, in practical application, the lock body 4 is provided with the main body 5, three sets of jackscrews are uniformly distributed on the main body 5, the outer ejector rod 8 is a combined structure of a cylinder and a hemisphere, the pressing ring 6 covers the cylinder of the outer ejector rod 8, and as the pressing ring 6 is a circular ring structure, the inner diameter of the pressing ring 6 is adapted to the diameter of the outer ejector rod 8; the pressure spring 7 is composed of a support ring and an effective ring, and the pressure spring 7 is sleeved on the outer side of the outer ejector rod 8.

In practical application, the oil theft preventing device is installed at the emptying valve of the sleeve, and a special key of the device is screwed in, so that the device is expanded in the inner diameter of the sleeve, the flow of an oil outlet is effectively reduced, and the aim of preventing oil theft is fulfilled.

In the oil theft preventing device, each set of device corresponds to the respective lock cylinder and key, so that the keys of all wells are different, and all devices cannot be invalid due to the fact that one key is lost in actual production.

The working principle of the internal expansion type sleeve oil stealing prevention device is described in detail as follows:

in the embodiment, firstly, the lock cylinder 3 and the special key 1 are forcibly connected through a matched wrench, wherein a connecting buckle of the lock cylinder 3 and the special key 1 is a left-hand buckle; secondly, the key 1 and the lock cylinder 3 are connected into an integral part and connected with the lock body 4 through a matched wrench, wherein the lock cylinder 3 and the lock body 4 are connected into a right buckle.

In practical application, firstly, a worker needs to rotate the special key 1, the special key 1 moves to drive the lock cylinder 3 to screw into the lock body 4, the lock cylinder 3 jacks up three jack screws of the lock body 4 in the screwing-in process, the anti-theft oil device can be tightly tensioned in the inner diameter of a vent of a sleeve, and when the rotation of the anti-theft oil device reaches a certain torque force, the special key 1 naturally falls off, and the anti-theft oil device is installed.

In actual production, the oil pumping unit is required to be stopped before oil drainage, the oil pumping unit is required to be stopped for 4 hours each time averagely, the average influence on the yield is between 0.5 and 1 ton, and in actual application, 15 sets of oil anti-theft devices are installed in our factory, so that the yield caused by oil drainage due to stopping is effectively reduced, and the economic loss is greatly reduced.

It should be noted that in the practical application of this embodiment, some auxiliary tools need to be manufactured to cooperate with the operation of the oil theft preventing device, which is specifically as follows: firstly, a bush with internal threads and a jackscrew is required to be manufactured and is inlaid in a hollow opening; secondly, a matched plug with positive and negative threads is required to be manufactured and screwed into the lining; thirdly, special sleeves with different thread sizes need to be made; fourthly, the reverse-threaded plug and the positive plug are connected in a threaded mode, and the built-in jackscrew is expanded and tightened while the plug is screwed in.

In the embodiment, the oil stealing prevention device is simple in structure, can be quickly installed in practical application, and blocks the opening of the emptying gate through the conical lock cylinder, so that the oil stealing prevention effect is achieved, and the environmental pollution caused by oil stealing and draining can be effectively avoided.

In practical application, the oil theft preventing device is arranged outside the gate from the outside, belongs to an external device, does not influence the integral structure of the gate, and does not have potential safety hazard in the installation and disassembly processes; in addition, because the oil theft preventing device is arranged at the emptying port of the sleeve, the exposed part of the device has no stress point of a disassembling tool, so that an oil thief cannot randomly disassemble the oil theft preventing device; simultaneously, this theftproof oily device can form annular space with the internal diameter of emptying gate, through the clearance of reserving, effectively avoids because the phenomenon is suppressed to pressure that too sealed caused.

It should be noted that, for the convenience of production, aiming at the conditions of low-pressure testing, well washing, operation and the like in practical application, an oil extraction worker can take out the device at any time through a special key so as to match with related construction, and in practical application, any construction progress cannot be influenced by the installation of the oil theft prevention device, so that the oil theft prevention device can be taken at any time in any purpose.

The utility model provides a pair of internal expanding sleeve pipe theftproof oil device installs the theftproof oil lock at sheathed tube atmospheric valve, and the oil outlet well head of effective prevention beam-pumping unit is destroyed by lawless persons, stops theftproof oil incident from the root, has not only reduced the output loss of crude oil, can also avoid peripheral environment to receive the pollution.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
