The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Fig. 1 is the utility model discloses an embodiment of the adjustable protection well lid of setting in the well is the intention, as shown in fig. 1, this adjustable protection well lid of setting in the well is including setting up the fence body 1 in the well, fence body 1 includes pull inner tube 2, and the cover is established on the pull inner tube 2 and can along the pull outer tube 3 that the pull inner tube 2 removed, be provided with a plurality of carrier tubes 4 on the pull outer tube 3, preferably vertically set up carrier tube 4, also can incline and set up carrier tube 4. Offer on the carrier tube 4 and supply a hole 6 that branch pipe 5 passed, can be a plurality of branch pipe 5 parallel arrangement passes a hole 6 will be a plurality of carrier tube 4 couples together the free end of pull inner tube 2 is provided with articulated body T1, through the articulated body can with adjustable protection well lid is installed at the well inner wall the tip of pull outer tube 3 is provided with the locking the tool to lock 9 of adjustable protection well lid.

The equipment can increase the protection scope of this well lid through the sheathed tube of multiple sheathed tube to the fence body 1, adapts to the well of multiple different specification diameters, has strengthened the adjustable performance of this well lid, makes it nimble changeable, and the form is no longer single, and the assembly and disassembly is simple, convenient to carry.

Through set up protection well lid in the well, can still can carry out safety protection to the interior facility of well in the impaired back of ground well lid at the well head. And this kind of protection well lid of pull formula can be according to well bore size and rationally set up the length of pull inner tube and pull outer tube to and set up length, compound mode, combination shape and density of bearing pipe and branch pipe, these pipe fittings are put together through the concatenation, therefore the flexibility of adjustment size is stronger, does not just fix the shaping at the well lid of one shot forming back structure like the disposable casting.

Preferably, the pull inner tube 2 with the cooperation is established to the radial cross sectional shape looks adaptation of pull outer tube 3, the two cover of being convenient for, in this embodiment, the two cross sectional shape is square, can be multiple shape in the reality, like circular, trapezoidal, rhombus etc. not only the utility model discloses. Adopt this square shape, can strengthen the pull inner tube 2 is in the stability in the pull outer tube 3 for the two can not take place relative position and rotate, has further guaranteed the cover and has established the stability of bearing tube 4 on the pull outer tube 3, wear to establish branch pipe 5 on the bearing tube 4 is the pipe, can increase the torsional strength of branch pipe 5, in actual conditions, if need increase the bending strength of branch pipe 5, can change branch pipe 5 into square pipe, branch pipe 5 shape can have multiple selection, like rhombus, trapezoidal, oval etc. is not limited to this embodiment. And set up to square pipe be favorable to in the inside slide rail that sets up of pull inner tube 2, be convenient for pull relative motion between pull inner tube 2 and the pull outer tube 3.

Preferably, the diameter of the outer drawing tube 3 is slightly larger than that of the inner drawing tube 2, so that the outer drawing tube 3 can move along the inner drawing tube 2 conveniently.

Preferably, as shown in fig. 2, a plurality of first fixing holes 11 are formed on the drawn outer tube 3 and the carrier tube 4, which correspond to each other in position and are used for fixedly combining the drawn outer tube 3 and the carrier tube 4.

The distance between the first fixing holes 11 determines the density of the carrier tube 4 along the outer drawn tube 3. Preferably, the first fixing holes 11 are arranged at equal intervals, which is beneficial to balancing the whole adjustable well lid, so that the whole adjustable well lid is not prone to gravity center shift and inclination.

The bearing pipe 4 and the branch pipe 5 are provided with a plurality of second fixing holes 12 which correspond to each other in position and are used for fixedly combining the bearing pipe 4 and the branch pipe 5.

The spacing distance of the second fixing holes 12 determines the density of the branch pipes 5, and preferably, the second fixing holes 12 are equally spaced and have similar functions to the first fixing holes 11, which is not described herein again.

The pipe body of the drawing outer pipe 3 is provided with a plurality of spacing distances between the first fixing holes 11 can be adjusted according to the actual well size, so that the bearing pipes 4 with proper quantity are arranged, the range of the radiation protection of the well cover can be adjusted by arranging the bearing pipes 4 with different spacing distances, and better safety interception and protection effects are achieved.
