Technical Field

[0001] This utility model belongs to the field of mining equipment technology and relates to a water-proof device for observation holes in sealed walls. Background Technology

[0002] In coal mining operations, sealing off roadways that are not in use for a long time or temporarily is a key measure to ensure underground safety. The sealed walls need to be inspected regularly to address potential safety hazards caused by changes in gas and water accumulation and coal oxidation within the roadway. The traditional inspection method is drilling.

[0003] However, traditional sealed-wall observation wells have significant problems: they are prone to water accumulation. This not only directly causes inconvenience in observation operations and greatly hinders drainage work during observation, but also affects the accuracy of observation data and may even damage the detection equipment, thereby increasing equipment maintenance costs. Therefore, the problem of observation inconvenience caused by water accumulation in the observation wells is an urgent issue that needs to be addressed in existing technologies. Utility Model Content

The return water pipe is embedded in the observation hole of the sealed wall. One end of the return water pipe is connected to the inner space of the sealed wall, and the other end of the return water pipe is connected to a drainage and gas collection device located on the outside of the sealed wall. A return water pipe valve is provided at the end of the return water pipe near the drainage and gas collection device.

[0006] The present invention is further characterized in that: The drainage and gas collection device includes a water guide pipe, which is set vertically. A water inlet pipe is vertically connected to the middle of the water guide pipe. The inlet end of the water inlet pipe is connected to the return water pipe. Straight-through valves are installed at both ends of the water guide pipe. A drainage device is installed near the bottom of the water guide pipe.

[0007] The inlet end of the water inlet pipe is connected to the return water pipe via a quick connector.

[0008] There are two water inlet pipes, which are symmetrically arranged on both sides of the water guide pipe.

[0009] The water pipe has a vertical hollow structure. The upper part of the water pipe is a vertical straight pipe section, and the lower part of the water pipe is bent to form a U-shaped pipe section. The bottom of the U-shaped pipe section is connected to the drainage device.

[0010] The drainage device includes a drain pipe that is connected to the bottom of a U-shaped pipe section, and a shut-off valve is installed on the drain pipe.

[0012] The surface of the transparent scale window is engraved with scale lines, and the length of the transparent scale window is adapted to the length of the vertical straight section of the water pipe.

[0013] The beneficial effects of this utility model are: This utility model relates to a water-proof device for observation holes in sealed walls. The device connects to a drainage and gas collection device via a return water pipe, allowing water from the observation hole to flow into the drainage and gas collection device, preventing water accumulation in the observation hole and backflow. Simultaneously, the water guide pipe in the drainage and gas collection device uses gravity to achieve gas-water separation.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] This utility model relates to a water-proof device for observation holes in sealed walls, such as... Figure 1 and Figure 2 As shown, it includes a return water pipe 2, which is embedded in the observation hole of the sealed wall 1. One end of the return water pipe 2 is connected to the inner space of the sealed wall 1, and the other end of the return water pipe 2 is connected to the drainage and gas collection device located on the outside of the sealed wall 1. A return water pipe valve is provided at the end of the return water pipe 2 near the drainage and gas collection device. The function of the return water pipe 2 is to guide the water flow into the drainage and gas collection device, prevent water from accumulating in the observation hole and causing backflow, and effectively solve the problem that the observation hole of the sealed wall is often inconvenient to observe due to water accumulation.

[0018] The drainage and gas collection device includes a water guide pipe 5, which is vertically installed. A water inlet pipe 3 is vertically connected to the middle of the water guide pipe 5. The inlet end of the water inlet pipe 3 is connected to the return water pipe 2, allowing water from the return water pipe 2 to be introduced into the water guide pipe 5 through the water inlet pipe 3. Straight-through valves 6 are installed at both ends of the water guide pipe 5, and a drainage device is installed near the bottom of the water guide pipe 5. The straight-through valve 6 on the straight section of the water guide pipe 5 is used to release gas from the upper part of the straight section for detection purposes, while the straight-through valve 6 on the U-shaped section of the water guide pipe 5 discharges water accumulated in the U-shaped pipe.

[0019] The inlet end of the inlet pipe 3 is connected to the return pipe 2 via a quick connector 4, which allows for quick connection or disconnection of the inlet pipe 3 and the return pipe 2, simplifying the pipeline installation and maintenance process, reducing operational complexity, and shortening maintenance time; it also reduces the damage to the seal caused by frequent disassembly and assembly, ensures the system's sealing performance, and improves maintenance convenience.

[0020] There are two water inlet pipes 3, which are symmetrically arranged on both sides of the water guide pipe 5, providing two water inlet paths, namely left and right interface forms. Depending on the actual site conditions, a single pipe connection can be selected, such as the interface position of the sealed wall, the space of the alley, and the pipeline route, to avoid installation obstruction due to environmental restrictions.

[0021] The water guide pipe 5 has a vertical hollow structure. The upper part of the water guide pipe 5 is a vertical straight pipe section, and the lower part of the water guide pipe 5 is bent to form a U-shaped pipe section. The bottom of the U-shaped pipe section is connected to a drainage device. The upper vertical straight pipe section of the water guide pipe 5 is a gas separation zone, and the lower U-shaped pipe section of the water guide pipe 5 is a water storage zone. Gas-water separation is achieved by using gravity. The water sinks to the U-shaped pipe, and the gas floats to the straight pipe section. The U-shaped pipe section stores water to prevent overflow, and the straight pipe section accumulates gas for easy detection.

[0022] The drainage device includes a drainage pipe 7, which is connected to the bottom of the U-shaped pipe section. A shut-off valve 8 is installed on the drainage pipe 7. The drainage volume is adjusted by the shut-off valve 8, and the separated water is discharged through the drainage pipe 7 to remove excess water in a timely manner, maintain the effectiveness of gas-water separation, prevent water from accumulating in the U-shaped pipe, ensure that there is no liquid water interference in the gas detection area of ​​the straight pipe section, and ensure a stable observation environment.

[0023] A transparent scale window 9 is provided on the side wall of the vertical straight pipe section of the water guide pipe 5. The connection edge between the transparent scale window 9 and the inside of the water guide pipe 5 is filled with sealant.

[0024] The surface of the transparent scale window 9 is engraved with scale lines. The length of the transparent scale window 9 is adapted to the length of the vertical straight section of the water pipe 5. The water level in the water pipe can be monitored visually through the transparent scale window 9. The scale lines quantify the water level and record the trend of change, providing data support for mine safety decisions.

[0025] The specific working process of this utility model's sealed wall observation hole anti-water ingress device is as follows: When conducting observations, open the straight-through valve 6 at the bottom of the water pipe 5 to drain water in advance. If the water volume is too large, the shut-off valve 8 can be opened for rapid drainage. The gas undergoes vapor-water separation in the water pipe 5. Due to gravity, water enters the lower U-shaped section of the water pipe 5, while the gas to be detected is stored in the upper vertical pipe of the water pipe 5. During inspection, open the straight-through valve 6 at the top of the water pipe 5 for inspection.
