Description

Well head theftproof well lid

Technical Field

The invention relates to a wellhead anti-theft device, in particular to a wellhead anti-theft well lid.

Background

In the continuous development process of oil and gas fields, partial oil and gas wells are shut down for a long time (more than one year) because the normal production needs cannot be met, more and more abandoned wells are generated due to geology, engineering or other reasons, some well heads are located in remote areas, oil recovery teams and groups are neglected in management, permanent sealing and injection are not performed, theft is not prevented, once crude oil overflows, the environment is polluted, accidents are caused, irrecoverable loss is caused, and the image of an enterprise is also adversely affected.

At present, an anti-theft device is formed by pouring an anti-theft cement cap and reinforced cement, and is extremely heavy, hoisting equipment such as a crane and the like must be used during moving, pressure measuring and pressure releasing, a large amount of manpower and equipment are required in the implementation process, and the construction is complicated; sometimes even the well mouth is welded to be dead, so that the work of recording pressure, sealing packing tightly and the like can be finished only by cutting off the packing through electric welding.

Disclosure of Invention

Aiming at the problems, the invention provides the wellhead anti-theft cover which is simple in structure, convenient to install, convenient and fast to operate and safe in anti-theft.

The invention is realized by the following technical scheme:

a well mouth theft-proof well lid, including well lid 1, fixed hole 2, stationary part 3, inserted bar stationary part 4, inserted bar 5, lock seat 6, the first handle 7, the second handle 8, the third handle 9; a plurality of fixing holes 2 are arranged at positions of the well cover 1, which are at a certain distance from the edge; the fixing pieces 3 respectively penetrate through the fixing holes 2 and are connected with a wellhead; the inserted bar fixing pieces 4 are respectively arranged on one side of the top surface of the well lid 1 where any two opposite fixing holes 2 are connected, and the lock seat 6 is arranged on the other side of the connecting line of the fixing holes 2; the inserted link 5 is fixed by an inserted link fixing part 4, a first handle is arranged on the inserted link 5, and a through hole which is suitable for the lock seat 6 is arranged on the handle at a certain distance from the inserted link 5; the second handle 8 and the third handle 9 are respectively arranged on two sides of the inserted rod 5, are far away from the inserted rod 5 and are connected with the jacks parallel to the inserted rod 5.

Preferably, the plurality of fixing holes 2 are arranged in a hexagonal shape on the well lid.

Preferably, inserted bar mounting 4 sets up in the inboard certain distance department of circle of fixed orifices 2 place, and 5 both ends of inserted bar set up the visor that is adapted to mounting 4 respectively, and inserted bar 5 length surpasss well lid 1 length certain distance.

Preferably, the first handle on the inserted link 5 is buckled on the lock seat 6, and locked.

The invention has the advantages that:

1) the anti-theft well lid assembly comprises a well lid body, a fixing device and an anti-theft lock device, and the well lid body, the fixing device and the anti-theft lock device are matched to jointly protect a well mouth;

2) the fixing holes are arranged in a hexagon shape, so that the function of the shackle device is easy to realize, meanwhile, multi-point fixing can be realized, and the anti-theft capacity is improved.

3) The inserted bar mounting 4 sets up in the inboard certain distance department of the circle of fixed orifices 2 place, and 5 both ends of inserted bar set up the visor 10 that is adapted to mounting 3 respectively, and inserted bar 5 length surpasss well lid 1 length certain distance, can't open mounting 2 under the condition of not opening the lock, open well lid 1, steal crude oil.

4) The length of setting for of inserted bar 5 is greater than well lid 1, can make inserted bar 5 embedded in the well head correspond the draw-in groove of position department setting for, increases the theftproof effect.

5) The invention has simple structure, convenient installation, convenient operation and strong anti-theft capability.

Detailed Description

The invention is described in detail below with reference to specific embodiments.

Example one

The invention provides a well mouth anti-theft well lid, which comprises a well lid 1, a fixing hole 2, a fixing piece 3, an inserted bar fixing piece 4, an inserted bar 5, a lock seat 6, a first handle 7, a second handle 8 and a third handle 9; a plurality of fixing holes 2 are arranged on the top surface of the well lid 1 at a certain distance from the edge, and the fixing pieces 3 respectively penetrate through the fixing holes 2 to be connected with a well mouth; the inserted bar fixing parts 4 are respectively arranged on one side of the connecting line of any two opposite fixing holes 2; the lock seat 6 is arranged at the other side of the connecting line of the fixed hole 2; the inserted link 5 is fixed by an inserted link fixing part 4, a first handle 7 is arranged on the inserted link 5, and a through hole which is suitable for the lock seat 6 is arranged on the handle at a position away from the inserted link 5; the second handle 8 and the third handle 9 are respectively arranged on two sides of the inserted rod 5 and are far away from the inserted rod 5, and the two sides of the inserted rod are connected with the jacks parallel to the inserted rod 5.

Preferably, a plurality of fixing holes 2 are arranged in a hexagonal shape on the well cover

The beneficial effect of this embodiment is: the hexagon has three opposite sides which are parallel to each other, and after any two fixing holes 2 in the opposite angle direction are connected, two sides which are parallel to the hexagon are inevitably arranged, so that the arrangement of the second handle 8 and the third handle 9 and the combination of the protective cover 10 on the inserted link 5 and the fixing piece 3 in the anti-theft lock structure are convenient.

Example two

Preferably, the inserted bar fixing piece 4 is arranged at a certain distance on the inner side of the circle where the fixing hole 2 is located, the two ends of the inserted bar 5 are respectively provided with a protective cover 10 adapted to the fixing piece 3, and the length of the inserted bar 5 exceeds the length of the well lid 1 by a certain distance.
