Description

Technical Field

[0001] This utility model relates to the field of dust suppression equipment in mines, specifically a two-way control device for a dust suppression water curtain in a filling branch roadway, which is applied to the tunneling branch roadway in the integrated mechanized unit compact filling coal mining process. Background Technology

[0002] In coal mine tunnels, dust-proof and cooling water curtain devices are installed according to coal mine regulations. Workers need to operate the water curtain themselves to pass through it, sometimes using a screen to shield themselves from the water. After passing through, their clothes get wet, causing them to catch colds or contract other diseases. This not only affects the comfort of workers' clothing but also has a greater impact on their health. Currently, the water curtain's operation is generally controlled by a dual-control mechanical rotation valve. However, the manual operation of the mechanical valve, due to frequent and varying degrees of force and method of operation, can easily damage or even malfunction the valve, preventing the water curtain from closing completely and affecting both pedestrian passage and production.

[0003] Designing a device that can automatically close the water curtain when people pass through and automatically restart it after people leave will undoubtedly bring a better experience to workers and ensure their comfort and safety when entering and exiting tunnels. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a bidirectional control device for a dust suppression water curtain in a filling branch roadway. When workers enter or exit the roadway, the working status of the water curtain is automatically controlled by the illumination of their miner's lamps, eliminating the need for manual operation and ensuring comfort and safety when passing through the water curtain.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bidirectional control device for a dust suppression water curtain in a filling tunnel includes a water supply pipe, a connecting pipe, and a spraying mechanism. The water supply pipe is located on the top of the pedestrian side of the tunnel entrance and is connected to the spraying mechanism via the connecting pipe. The spraying mechanism consists of multiple water curtains spaced at intervals, each controlled by a corresponding water curtain switch. The bidirectional control device includes a water curtain solenoid valve, a control circuit, and two photosensitive controllers. Two photosensitive controllers are located on the front and rear sides of the spraying mechanism, respectively. The control circuit is connected in series with the water curtain solenoid valve. The water curtain solenoid valve is connected in series with multiple water curtain switches. The control circuit consists of switches S1 and S2. Switch S1 is located in front of the first water curtain, and switch S2 is located behind the last water curtain. Switches S1 and S2 are connected in series. The two photosensitive controllers are connected to switches S1 and S2, respectively.

[0007] The opening and closing of switch S1 in the control circuit is controlled by a photosensitive controller one on the front side of the first water curtain. When the miner's lamp shines on the photosensitive controller one, the photosensitive controller one controls switch S1 to open, the water curtain solenoid valve to close, and multiple water curtain switches controlling multiple water curtains to close, the water spraying mechanism to stop working. After personnel pass through, switch S1 automatically closes, and multiple water curtains continue to work. When personnel pass through the water curtain in the opposite direction, the photosensitive controller two on the back side of the last water curtain receives the miner's lamp light and controls switch S2 to open, the water spraying mechanism to stop working, and after personnel pass through, switch S2 automatically closes, the water curtain solenoid valve to open, and multiple water curtains continue to work.

[0008] The switches S1 and S2 meet the MA requirements, with the specifications set as rated input AC100-240V, output AC100-240V, and current 10A / 20A.

[0009] The water curtain solenoid valve meets MA requirements, adopts an explosion-proof structure, has a protection level of not less than IP65, can operate stably in medium temperatures ranging from -20℃ to 70℃, is made of corrosion-resistant materials, supports mechanical, hydraulic or pneumatic control, and can fully open / fully close the pipeline fluid.

[0010] This invention presents a bidirectional automatic control device for traditional two-stage dust removal and cooling water curtains in roadways. It eliminates the need for manual valve operation; workers simply illuminate one side of the water curtain with their miner's lamp to automatically close it, and the water curtain automatically resumes operation after passage. The device is simple in structure and low in cost, avoiding the wear and tear on mechanical valves caused by manual operation and the potential for workers to get their clothes wet. It provides a barrier to ensure the comfort and health of workers when passing through the water curtain, and the automated design reflects a human-centered approach. The use of light sensors avoids sparks from circuit switches, ensuring worker safety and making it suitable for large-scale application in the industry. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1-3As shown, this bidirectional control device for dust suppression water curtain in a filling branch tunnel includes a water supply pipe 5, a connecting pipe 6, and a water spraying mechanism 7. The water supply pipe 5 is located on the top of the pedestrian side of the tunnel 8 and is connected to the water spraying mechanism 7 via the connecting pipe 6. The water spraying mechanism 7 is configured as multiple water curtains with spacing between them, each controlled by a corresponding water curtain switch 9. The bidirectional control device includes a water curtain solenoid valve 3, a control circuit 2, and two photosensitive controllers 4. The two photosensitive controllers are located on the front and rear sides of the water spraying mechanism 7, respectively. The control circuit 2 is connected in series with the water curtain solenoid valve 3. The water curtain solenoid valve 3 is connected in series with multiple water curtain switches 9. The control circuit 2 consists of switches S1 and S2. Switch S1 is located in front of the first water curtain, and switch S2 is located behind the last water curtain. Switches S1 and S2 are connected in series. The two photosensitive controllers 4 are connected to switches S1 and S2, respectively.

[0016] As a preferred embodiment, in this embodiment, the switches S1 and S2 meet the MA requirements, with the specifications set as rated input AC100-240V, output AC100-240V, and current 10A / 20A.

[0017] As a preferred embodiment, the water curtain solenoid valve 3 meets MA requirements and is suitable for explosive gas environments such as methane and coal dust. The valve adopts an explosion-proof structure with a protection level of not less than IP65, and can operate stably in media temperatures ranging from -20℃ to 70℃. The valve body is made of corrosion-resistant materials such as aluminum alloy or 316L stainless steel, and the sealing material is NBR / FKM, which has strong corrosion resistance. It meets DC 24V or AC 220V power supply requirements, has a power consumption as low as 16.5W, supports mechanical, hydraulic, or pneumatic control, and can fully open / fully close the pipeline fluid.

[0018] Due to the special application scenario of this utility model, all switches and solenoid valves in this solution should meet the relevant requirements of MT 113-1995 "General Test Methods and Judgment Rules for Flame Retardancy and Antistatic Properties of Polymer Products Used in Coal Mines". The light sensor controller is a waterproof, discharge-proof, and gas-proof light sensor element that can avoid sparks generated by circuit switches and provide protection for personnel safety.

[0019] In the specific application of this utility model, the opening and closing of switch S1 in the control circuit 2 is controlled by the light sensor controller 41 on the front side of the first water curtain. When the miner's lamp shines on the light sensor controller 41, the light sensor controller 41 controls switch S1 to open, the water curtain solenoid valve 3 to close, the multiple water curtain switches 9 controlling the multiple water curtains to close, the water spraying mechanism 7 to stop working, and after personnel pass through, switch S1 automatically closes, and the multiple water curtains continue to work; when personnel pass through the water curtain in the opposite direction, the light sensor controller 42 on the back side of the last water curtain receives the miner's lamp illumination and controls switch S2 to open, the water spraying mechanism 7 to stop working, and after personnel pass through, switch S2 automatically closes, the water curtain solenoid valve 3 is turned on, and the multiple water curtains continue to work.

[0020] By designing such a two-way control device, personnel can pass through the water curtain in the tunnel without manually operating the water curtain switch. They simply need to shine a light sensor on the controller using their worn miner's lamp. The light sensor then controls the control circuit switch on that side to disconnect, indirectly controlling the water curtain solenoid valve and the water curtain switch to disconnect, stopping the water curtain from working. This allows personnel to pass safely without getting their clothes wet. The directional operation is the same, making it safe and convenient. It avoids the wear and tear on the valves caused by frequent manual operation of the water curtain switch, which could affect its opening and closing function. The control circuit design is simple, low-cost, and easy to implement, saving costs while ensuring the comfort and safety of personnel passing through.

[0021] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
