Abstract
The utility model discloses a vertical matching structure of a well body and a deepening pipe, which comprises a well head, wherein the well head is in an annular convex shape; the deepening pipe is provided with a columnar cavity, and the bottom end of the deepening pipe is nested on a well head; the outer wall of the well mouth is a slope surface, and the opening at the bottom end of the deepening pipe is an inclined surface matched with the slope surface of the well mouth. Through the embedded type folding structure of the wellhead and the deepening pipe, the manufacturing cost is low, the realization is easy, and the sealing effect is good.
Description
Technical Field
The utility model belongs to the field of reinforced structures, and particularly relates to a vertical matching structure of a well body and a deepening pipe.
Background
Along with the construction process of electric devices and automation devices in China, the construction and protection of the automation devices in the industries of electric power, communication, water conservancy and the like become a working key point.
The depth of a pre-embedded well body in the existing industry is deep, so that how to ensure that an operator can smoothly go into the well during maintenance is difficult, and a circuit led out from the well body can obtain an effective protective environment.
SUMMERY OF THE UTILITY MODEL
The utility model provides a vertical matching structure of a well body and a deepened pipe, which at least solves the problem that the prior art can not provide an effective closed environment for the deepened pipe.
The technical scheme is as follows:
a vertical matching structure of a well body and a deepening pipe comprises
The well head is in an annular convex shape;
the deepening pipe is provided with a columnar cavity, and the bottom end of the deepening pipe is nested on a well head;
the outer wall of the well mouth is a slope surface, and the opening at the bottom end of the deepening pipe is an inclined surface matched with the slope surface of the well mouth.
Furthermore, the deepening pipe is a cylinder formed by splitting the diameter into two petals.
Furthermore, the top of the deepening pipe is provided with a convex ring for butt joint, and the convex ring is consistent with the shape of the wellhead.
Furthermore, the outer diameter of the convex ring is smaller than the inner diameter of the opening at the bottom end of the deepened pipe.
Furthermore, a climbing ladder communicated to the wellhead is inserted into the deepened pipe.
Furthermore, a sealing groove 2a is formed in the position where the bottom end of the deepening pipe is matched with the wellhead along the inner wall of the deepening pipe, and a sealing ring is embedded in the sealing groove 2 a.
Furthermore, a plurality of deepening pipes are coaxially and sequentially assembled above the deepening pipe.
Furthermore, the number of the deepening pipes is a plurality of and is butted along the vertical direction in sequence.
Drawings
The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the utility model and together with the description serve to explain the utility model without limiting the utility model.
Fig. 1 is an example of an axial view structural diagram for achieving the object of the present invention.
Fig. 2 is an enlarged view of the sealing groove 2a of the present invention.
FIG. 3 is a view showing the structure of the convex ring of the present invention.
Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1, as shown in FIGS. 1-2, there is provided a vertical mating structure of a well body and a deepened pipe, comprising
The wellhead 1 is in an annular convex shape;
the deepening pipe 2 is provided with a columnar cavity, and the bottom end of the deepening pipe is nested on the wellhead 1;
the outer wall of the wellhead 1 is a slope surface, the bottom opening of the deepening pipe is an inclined plane matched with the slope surface of the wellhead, and the joint of the wellhead and the deepening pipe is combined with the slope surface through sealing glue.
The main improvements of the utility model are as follows:
by providing the embedded closure structure of the wellhead and the deepening pipe and combining the sealant with the inclined surface of the closure structure, the sealing performance of the interface can be effectively guaranteed, the manufacturing cost is low, the construction method is easy to realize, and the workload of operators can be reduced.
As shown in fig. 1, the plurality of the deepening pipes are sequentially butted in the vertical direction.
Through will deepening the pipe and cut apart to use the rubber gasket to carry out auxiliary work in the junction, the rubber gasket can guarantee the anti leakage effect of fine junction under the extrusion, its effectual life that has improved.
As shown in figure 3, the top of the deepened pipe is provided with a convex ring 4 for butt joint, the convex ring 4 is in accordance with the shape of the wellhead, and the outer diameter of the convex ring 4 is smaller than the inner diameter of the opening at the bottom end of the deepened pipe. And a climbing ladder communicated to the wellhead is inserted into the deepened pipe.
As shown in figure 2, a sealing groove 2a is formed in the position, matched with a wellhead, of the bottom end of the deepened pipe along the inner wall of the deepened pipe, a sealing ring is embedded in the sealing groove 2a, and a plurality of deepened pipes are coaxially and sequentially assembled above the deepened pipes.
The main improvements of the utility model are as follows:
the sealing solution can be freely assembled by an operator, and the sealing ring is limited and is extruded on a wellhead by self in the process of pressing the deepening pipe, so that the structure is simple and efficient.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
