Description

Technical Field

[0001] The utility model relates to the technical field of coal mine safety equipment, in particular to a water discharger for a gas extraction pipe in a high-gas mine. Background Art

[0002] During the mining process of high-gas mines, gas extraction is one of the important measures to ensure safe production in mines. However, due to the complex geological conditions of mines, the long gas extraction pipelines and the easy accumulation of water, the efficiency and safety of gas extraction are seriously affected. Although the water dischargers in the existing technology can solve the problem of water accumulation to a certain extent, there are certain problems. Most of the water dischargers in the existing technology only have a simple water discharge function, and lack an effective filtering mechanism for impurities and particles in the gas. This design deficiency results in the inability to effectively intercept the tiny particles, dust and other impurities in the gas when it passes through the water discharger, and then enters the extraction system together with the gas. These impurities will not only accelerate the wear of the extraction equipment and reduce its service life, but may also clog the pipeline and cause safety accidents. At the same time, its water discharge process mostly relies on manual operation or simple mechanical structure, which is difficult to achieve precise control and automation. Utility Model Content

[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] Combined with attachment Figure 1 -Attached Figure 3 A water discharger for a gas extraction pipe in a high-gas mine comprises a water discharger shell 1, a height-adjustable support leg assembly being provided on the side of the water discharger shell 1, an upper cover 2 being provided on the water discharger shell 1, a negative pressure balancing valve 3 and a vent valve 4 being provided on both sides of the negative pressure balancing valve 3, a float 5 which can slide up and down being provided inside the water discharger shell 1, a water supply pipe 6 being provided on one side of the water discharger shell 1, a filter box 7 being provided on the water supply pipe 6 and a filter screen 8 being provided in the filter box 7, a water outlet pipe 9 being provided at the bottom of the water discharger shell 1, and a sealing member 10 for sealing the water outlet of the water outlet pipe 9 being provided at the bottom of the float 5.

[0021] In one embodiment, a lower end cap 11 is screwed to the bottom of the filter box 7, with a sealing gasket installed between the lower end cap 11 and the bottom of the filter box 7. The front and rear side panels of the filter box 7 each have through-holes for the water supply pipe 6 to pass through. Guide seats 12 are located on either side of the through-holes in the rear side panel of the filter box 7. Guide slots are located on opposite sides of the guide seats 12, and the filter screen 8 is retractable within the guide slots of the guide seats 12. In this embodiment, the design of the filter box 7 takes maintenance convenience into account. The lower end cap 11 is screwed to the bottom and is equipped with a sealing gasket. This not only ensures the tightness of the filter box 7 but also facilitates removal of the lower end cap 11 for internal cleaning or maintenance when necessary. The front and rear side panels of the filter box 7 have through-holes for the water supply pipe 6 to pass through, while the guide seats 12 and their guide slots on either side of the through-holes in the rear side panel provide a secure and easily replaceable mounting for the filter screen 8. This retractable design makes cleaning or replacing the filter screen 8 simple and quick, effectively extending the life of the water dispenser and ensuring water quality.

[0022] In one embodiment, the upper end of the float 5 is connected to a transverse plate 14 via a mounting rod 13. A sealing gasket 15 is installed on the transverse plate 14, corresponding to the position of the negative pressure balance valve 3. The transverse plate 14 also has a guide rod 16 extending into the vent valve 4, with a piston 17 installed at its upper end. This embodiment achieves precise control of the water level within the drain through the linkage mechanism formed by the float 5, mounting rod 13, transverse plate 14, guide rod 16, and piston 17. As the float 5 rises with the water level, the mounting rod 13 pushes the transverse plate 14 upward, which in turn drives the piston 17 on the guide rod 16 to move within the vent valve 4, opening the vent valve 4 and closing the negative pressure balance valve 3. This design cleverly utilizes the buoyancy of water as a power source, achieving automatic draining without the need for external energy. Simultaneously, the sealing gasket 15 on the transverse plate 14 ensures the tightness of the negative pressure balance valve 3 when closed, preventing gas leakage.

[0023] In one embodiment, a plurality of mounting posts 18 are provided on the circumference below the upper cover 2, and a retaining nut 19 is provided at the lower end of the mounting posts 18. The cross plate 14 is slidably mounted on the mounting posts 18. This embodiment provides a stable and flexible sliding track for the cross plate 14 by providing a plurality of mounting posts 18 below the upper cover 2 and installing a retaining nut 19 at the lower end of the mounting posts 18. The cross plate 14 can slide up and down smoothly along the mounting posts 18, thereby accurately responding to changes in the water level. This design not only improves the structural stability of the water discharger, but also ensures the stability and accuracy of the cross plate 14 during movement, further enhancing the reliability and service life of the water discharger.

[0024] In one embodiment, an upper magnet 20 is sleeved on the lower end of the vent valves 4 on both sides, and a lower magnet 21 corresponding to the position of the upper magnet 20 is provided on the horizontal plate 14. In this embodiment, an upper magnet 20 is sleeved on the lower end of the vent valve 4, and a lower magnet 21 corresponding thereto is provided on the horizontal plate 14. When the horizontal plate 14 descends to drive the piston 17 on the guide rod 16 to close the vent valve 4, the upper magnet 20 and the lower magnet 21 will attract each other, generating additional magnetic force to help stabilize the position of the piston 17 and prevent the piston 17 from accidentally moving due to factors such as vibration or airflow. This magnet-assisted design enhances the reliability of the closure of the vent valve 4 and ensures the sealing performance of the drainer under negative pressure.

[0025] In one embodiment, the upper cover 2 is removably mounted to the drain housing 1 via screws, with a sealing gasket positioned between the upper cover 2 and the housing 1. This design facilitates opening the upper cover 2 for internal inspection, repair, or component replacement when necessary. Furthermore, the presence of the sealing gasket ensures a tight seal between the upper cover 2 and the housing 1, preventing gas or moisture leakage. This detachable design improves the maintainability and flexibility of the drain, reducing maintenance costs.

[0026] In one embodiment, the leg assembly includes a mounting tube 22, within which a leg 23 slides. A support plate 24 is provided at the lower end of the leg 23. A locking screw 25 is threadedly connected to the side of the mounting tube 22 for securing the leg 23. By adjusting the position of the leg 23 within the mounting tube 22 and securing it with the locking screw 25, the height of the drain can be easily adjusted. This design allows the drain to adapt to various working environments and terrain conditions, enhancing its applicability and flexibility. Furthermore, the stable support plate 24 ensures the stability of the drain during use.

[0027] Working principle: In the specific implementation process of this application, an inlet check valve and an outlet check valve are respectively provided on the water supply pipe 6 and the water outlet pipe 9. The water supply pipe 6 and the negative pressure balance valve 3 are respectively connected to the bottom and the upper part of the gas pipeline. The water inlet check valve and the negative pressure balance valve 3 of the water supply pipe 6 are opened, and the vent valve 4 is closed. Under the action of the negative pressure of the gas pipeline, the water outlet check valve is in a closed state. At this time, the water in the gas pipeline enters the inside of the water discharger housing 1 through the water supply pipe 6 due to the action of gravity. When the float 5 rises, the blocking member 10 for blocking the outlet pipe 9 rises and detaches from the outlet pipe. 9 is blocked, and when the float 5 rises, it drives the cross plate 14 to rise. The cross plate 14 drives the piston 17 on the guide rod 16 to move upward in the vent valve 4, and the vent valve 4 is opened. The negative pressure balance valve 3 is sealed by the sealing gasket 15. At this time, the drain housing 1 is in a positive pressure state and the water outlet one-way valve is opened, thereby draining water. When the water in the drain housing 1 is gradually discharged, the float 5 will move downward as the water level drops. As the float 5 drops, the sealing member 10 connected to its bottom will also move downward, and eventually re-block the water outlet of the outlet pipe 9, preventing further drainage. This ensures that when the water level drops to a certain level, the water discharge process will automatically stop, avoiding excessive drainage. As the piston 17 on the guide rod 16 moves downward in the vent valve 4, the piston 17 will gradually block the passage of the vent valve 4, causing the vent valve 4 to close. At this point, due to the presence of a sealing gasket 15 beneath the negative pressure balancing valve 3, the downward movement of the horizontal plate 14 disengages the sealing gasket 15 from the lower port of the negative pressure balancing valve 3. This allows the gas line to reconnect to the interior of the drain housing 1 through the negative pressure balancing valve 3, restoring normal negative pressure. A height-adjustable leg assembly is mounted on the side of the drain housing 1, comprising a mounting tube 22, legs 23, a support plate 24, and locking screws 25. By adjusting the position of the legs 23 within the mounting tube 22 and securing them with the locking screws 25, the drain height can be easily adjusted to suit varying working environments and terrain conditions.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
