DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] As Figures 1 to 7 shown, an improved direct-buried waterproof well includes a wellhead part 1 and a well body part 2 which are sequentially and sealingly arranged from top to bottom. An openable and closable exhaust passage 11 is arranged on the outside of the wellhead part 1, and the exhaust passage 11 is in communication with the inside of the wellhead part 1. Correspondingly, the passage opening of the exhaust passage 11 is provided with a sealing plug (not shown in the figure). The exhaust passage 11 is arranged so that the sealing plug can be taken out regularly by an operator to discharge the deposited marsh gas in the waterproof well, and the sealing plug can also be taken out when necessary to connect external wires or antennas into the waterproof well through the exhaust passage 11, so as to facilitate the electrical connection between the electronic instruments in the waterproof well and external equipment and to meet the need of data transmission.

[0031] In actual use, the bottom of the well body part 2 can be sealed to serve as the well bottom of the waterproof well, or a well bottom can be additionally arranged below the well body part 2 to increase the stability. In the embodiment, the lower part of the well body part 2 is sealingly connected with a well bottom part 3. Specifically, the well bottom part 3 is installed on the ground at the bottom, the well body part 2 is installed on the top of the well bottom part 3, and the wellhead part 1 is installed on the top of the well body part 2. A connecting part 4 is sealingly arranged between the bottom surface of the wellhead part 1 and the top surface of the well body part 2. The cross-sectional area of the bottom of the connecting part 4 is larger than that of the top of the connecting part 4. Specifically, the connecting part 4 is in the shape of a tapering mouth from bottom to top, and the longitudinal cross section of the connecting part 4 is in the shape of a trapezoid. The well body part 2 and the wellhead part 1 are connected through the connecting part 4, and the size of the top of the connecting part 4 is adapted to the size of the bottom of the wellhead part 1. In this way, the size of the wellhead part 1 can be relatively small according to actual needs after the well body part 2 reaches the pre-designed size, which not only can adapt to the design needs of different users, but also can save the material of the wellhead part 1.

[0032] The well body part 2 comprises at least one connecting section 21, in practical application, the number of the connecting section 21 is determined according to the height of the pit, and is not limited in number, when there are more than two connecting sections 21, the connecting sections 21 are connected in sequence, it should be noted that in practical application, some pipelines are provided with electronic instruments, the waterproof well of the application needs to be installed at the position of the electronic instruments to protect the electronic instruments from being corroded by rainwater or waterlogging, therefore, at least one reserved hole 201 for installing the pipeline is arranged on one of the connecting sections 21, and the size of the reserved hole 201 is matched with the size of the corresponding pipeline.

[0033] The buried waterproof well of the application is integrally cast by using conventional metal corrosion-resistant materials, compared with the traditional well body made of bricks, cement and reinforced concrete, the overall weight is light, transportation is convenient, and since the well body and the connecting pipe 22 are not connected by using cement, the problem that the cement is corroded and water seeps, resulting in damage of the electronic instruments in the well body, does not occur.

[0034] The waterproof well of the application is divided into two installation modes of new installation and additional installation according to actual installation conditions, the new installation mode is that when the waterproof well needs to be newly installed, the well head part 1, the connecting part 4, the connecting section 21 and the well bottom part 3 are sequentially spliced into an integral waterproof well (if the number of the connecting sections 21 is more than one, the multiple connecting sections 21 are sequentially spliced to form the well body part 2) in advance in the factory, after the ground is excavated at the construction site, the spliced integral part is inserted into the ground, and then the gap is filled with mud to be flat, which greatly reduces the time of sealing the construction section, shortens the installation time, is more convenient for traffic, and the overall height can be adjusted by adjusting the number of the connecting sections 21 or replacing the connecting sections 21 of different heights, so as to adapt to the setting requirements of different depths.

[0035] The additional installation mode is that in actual use, the waterproof well of the application needs to be additionally installed on some pipelines provided with electronic instruments, so as to protect the electronic instruments from being corroded by rainwater or waterlogging, in order to facilitate the additional installation, the connecting section 21 is designed to be detachable, and the connecting section 21 is connected to the well head part 1 and the well bottom part 3 by bolts, and the connecting section 21 can be removed and replaced with a connecting section 21 of different height. Figure 6As shown, two connecting segments 21 can be arranged above and below, and corresponding positions between the two connecting segments 21 are respectively provided with semicircular mounting holes 202 matched with the pipeline, when the two connecting segments 21 are spliced together, the two semicircular mounting holes 202 are enclosed to form a complete reserved hole 201, and the inside of the connecting segment 21 is provided with a mounting seat for mounting the pipeline at the position corresponding to the reserved hole 201; during installation, the well bottom 3 is installed first, then the lower connecting segment 21 is installed below the pipeline, and the lower semicircular mounting hole 202 covers the lower part of the pipeline, then the upper connecting segment 21 is spliced with the lower connecting segment 21, so that the two semicircular mounting holes 202 are enclosed to form a complete reserved hole 201 to cover the pipeline, the two connecting segments 21 form the well body part 2, then the connection part 4 and the wellhead part 1 are spliced in turn to complete the installation of the waterproof well. In this way, the waterproof well can be installed without damaging the original pipeline, and installation is convenient.

[0036] It should be noted that in the conventional new installation method, a connecting pipe 22 is usually assembled at the position of the reserved hole of the connecting segment 21 according to actual needs to connect the existing pipeline, and the inside of the connecting segment 21 is provided with a mounting seat for mounting the pipeline at the position corresponding to the reserved hole. In this way, there is still a gap between the connecting pipe 22 and the connecting segment 21, and since they are two separate components assembled together, they may become loose and unstable after a long period of use. Preferably, in the present embodiment, the connecting pipe 22 and the connecting segment 21 are integrally formed, and the connecting pipe 22 is provided with an adapter at the end away from the connecting segment 21. The connecting segment 21 and the connecting pipe 22 are integrally formed by casting, which has high structural strength and good stability, and can effectively avoid the problem of loose connection between the connecting pipe 22 and the connecting segment 21 in the traditional assembly method, effectively improving the sealing degree of the waterproof well.

[0037] Preferably, as shown in FIG. 6, the waterproof well of the present embodiment is provided with a waterproof layer 5, and the waterproof layer 5 is arranged on the outer wall of the well body part 2 and the connection part 4.

Specifically, the side of the connecting pipe 22 away from the connecting section 21 is a spherical interface 221, and the side of the spherical flange connection port 23 opposite the connecting pipe 22 has a spherical connecting part 231 that can be clamped in the interface 221 and rotate with the interface 221. After the connecting part 231 of the spherical flange connection port 23 is clamped in the interface 221 of the connecting pipe 22, the spherical flange connection port 23 can rotate axially relative to the interface 221. Correspondingly, the position of the connecting part 231 of the spherical flange connection port 23 is also provided with a limiting buckle 232 for preventing the connecting part 231 from coming out of the interface, and the limiting buckle 232 is fixedly connected with the interface 221. Preferably, the position of the spherical flange connection port 23 close to the connecting part 231 is also provided with an annular limiting boss 233, which can limit the rotation angle of the spherical flange connection port 23 to avoid the case that the rotation angle is too large to cause the spherical flange connection port 23 to separate from the connecting pipe 22. The spherical flange connection port 23 can be flexibly adjusted to connect the angle, which is convenient for connecting the connecting pipe 22 with the external pipeline. In actual use, a flange connector can be arranged between the two connecting pipes 22 in the connecting section 21, and then the electronic instrument or flow meter can be installed between the two connecting pipes 22 through the flange connector.

[0039] Preferably, a plurality of third fixed convex rings 41 are arranged on the outer side of the connecting part 4, and the positions of the third fixed convex rings 41 correspond to the positions of the first fixed convex rings 20. After the well body part 2 and the well bottom part 3 are fixed by the bolt, the third fixed convex rings 41 can be passed through and wound on the bolt by using iron wire or steel wire or other conventional wire with certain hardness, so as to tightly fix the connecting part 4 with the well body part 2 and enhance the fixing effect between the connecting part 4 and the well body part 2. It should be noted that in addition to the above-mentioned fixing connection effect, the first fixed convex ring 20, the second fixed convex ring 31 and the third fixed convex ring 41 can also be used for hoisting and binding during the installation of the waterproof well, which is convenient for hoisting operation.
