[0018] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0020] Figure 2 In this utility model Figure 1 A sectional view. Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1

[0025] Reference Figures 1-2 This is the first embodiment of the present utility model. This embodiment provides a water-stopping sleeve for drilling water exploration and drainage, wherein the first locking member 102 and the second locking member 103 can prevent the connector 101 from falling off.

[0026] Specifically, the socket assembly 100 includes a connector 101, a first locking member 102, and a second locking member 103. The connector 101 is used to be installed on the drilled borehole for grouting and pressure testing, while the first locking member 102 and the second locking member 103 are used to prevent the connector 101 from falling off.

[0027] It should be noted that this anti-fall-off sleeve is assembled from inside the coal mine tunnel upwards. During assembly, all connecting parts 101 need to be connected together and then pushed upwards. Before pushing, the first locking part 102 and the second locking part 103 need to be bent outwards by 60°. In this way, the first locking part 102 and the second locking part 103 can act as barbs inside the borehole, thereby preventing the connecting parts 101 from falling downwards.

[0028] Example 2

[0029] Reference Figures 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that it specifically describes how the various connectors 101 are connected to each other.

[0030] The connector 101 includes a sleeve 101a, an externally threaded pipe 101b connected to one side of the sleeve 101a, and an internally threaded pipe 101c connected to the other side of the sleeve 101a. The inner wall of the sleeve 101a is provided with a grouting channel 101d, and the inner wall of the externally threaded pipe 101b is provided with a feed inlet 101e. The sleeve 101a is made of iron. The thickness of the internally threaded pipe 101c is less than the thickness of the sleeve 101a, and the diameter of the sleeve 101a is less than the diameter of the internally threaded pipe 101c. When it is necessary to connect the sleeves 101a together, the externally threaded pipe 101b at the top of the second sleeve 101a needs to be connected to the internally threaded pipe 101c at the bottom of the first sleeve 101a. This allows the two sleeves 101a to be connected together quickly.

[0031] It should be noted that when the two casings 101a are connected together, the various grouting channels 101d are interconnected, thus forming a complete pipeline.

[0032] Example 3

[0033] Reference Figures 1-2 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that it specifically explains how the first locking member 102 and the second locking member 103 prevent the connector 101 from falling downward.

[0034] Specifically, the first locking component 102 includes a first spike 102a, a first connecting end 102b disposed on one side of the first spike 102a, and a first abutting end 102c disposed on the other side of the first spike 102a. The first connecting end 102b is connected to the outer wall of the sleeve 101a. The first spike 102a is made of iron and is inclined. The second locking component 103 includes a second spike 103a, a second connecting end 103b disposed on one side of the second spike 103a, and a second abutting end 103c disposed on the other side of the second spike 103a. The second connecting end 103b is connected to the outer wall of the sleeve 101a. Next, the second spike rod 103a is made of iron and is inclined. The first connecting end 102b and the second connecting end 103b are welded to the sleeve 101a. Therefore, the first spike rod 102a and the second spike rod 103a can be directly bent by other instruments to make the first spike rod 102a and the second spike rod 103a fit more closely to the inner wall of the drilled pipe. In this way, when the sleeve 101a falls downward, the first contact end 102c and the second contact end 103c on the first spike rod 102a and the second spike rod 103a will abut against the inner wall of the drilled pipe, thereby preventing the sleeve 101a from falling.
