Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a wireless automatic water curtain sprayer to solve the problems of poor adaptability, insufficient protection performance and poor electrical connection stability of existing wireless automatic water curtain sprayers mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wireless automatic water curtain spray frame, including an arc-shaped streamlined main frame body, the surface of which is coated with an epoxy resin coating after being treated with chromate, and a multi-port connector is fixedly provided in the middle of the inner side of the arc-shaped streamlined main frame body.

[0009] The multi-port connector has a main water pipe interface and a main air duct interface at its two ends, and an electrical equipment interface, which is a multi-core aviation plug, is provided in the middle of the outer surface of the multi-port connector.

[0010] As a further improvement to the above solution, four branch water pipe interfaces are symmetrically distributed on the outer surface of the multi-port connector near the main water pipe interface, and four branch air pipe interfaces are symmetrically distributed on the outer surface of the multi-port connector near the main air pipe interface.

[0011] As a further improvement to the above solution, a controller is installed inside the curved streamlined main frame, and four spherical hinge bases are symmetrically distributed inside the curved streamlined main frame with the multi-port joint as the center.

[0012] As a further improvement to the above solution, a spherical connecting shaft is provided on the spherical hinge base, and a spray head is connected to the end of the spherical connecting shaft away from the spherical hinge base. The outer surface of the spherical hinge base is equipped with a fastening handle for locking the spherical connecting shaft.

[0013] As a further improvement to the above solution, the outer surface of the spray head is symmetrically provided with two connecting interfaces, and each branch pipe interface is connected to one of the connecting interfaces of the corresponding spray head through a high-pressure hose.

[0014] As a further improvement to the above solution, each of the branch duct interfaces is connected to another connecting interface of the corresponding spray head through a high-pressure hose. Both ends of the high-pressure hose are equipped with quick-connect fittings that are compatible with the branch water pipe interface, the branch air pipe interface and the connecting interface, and the hose body adopts a high-pressure resistant steel wire braided layer structure.

[0015] As a further improvement to the above solution, the sides of the arc-shaped streamlined main frame are symmetrically provided with fixed support plates, and the fixed support plates are provided with elastic pipe clamps.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This wireless automatic water curtain sprayer, with its curved streamlined main frame, not only adapts to the installation needs of different spaces, but its smooth shape also reduces airflow resistance and improves the stability of the equipment in complex environments. The epoxy resin coating applied after chromate treatment forms a tight protective barrier, significantly enhancing the corrosion resistance and wear resistance of the main frame, effectively extending the service life of the equipment in harsh environments such as humid and dusty conditions. The multi-connector integrates the main water pipe interface, the main air duct interface, and the multi-core aviation plug-type electrical equipment interface, consolidating the water, air, and electrical circuits. This simplifies the overall structural layout, reduces the clutter of pipes and lines, and facilitates installation and subsequent maintenance. The multi-core aviation plug also ensures the stability and safety of the electrical connection, providing reliable signal transmission for the automated control of the equipment.

[0018] 2. This wireless automatic water curtain sprayer features a spherical hinge base and a fastening handle, facilitating flexible adjustment of the spray head. The cooperation between the spherical connecting shaft and the spherical hinge base allows the spray head to rotate freely within a 0-90° range, enabling precise adjustment of the spray angle according to actual spraying needs. This ensures that the water curtain covers every corner of the target area, avoiding blind spots. The fastening handle locks the spherical connecting shaft after the spray head angle is adjusted, preventing the spray head angle from shifting due to vibration or other factors during equipment operation, thus ensuring the stability and consistency of the spraying effect.

[0019] 3. This wireless automatic water curtain sprayer enhances the practicality and reliability of the equipment by incorporating high-pressure hoses and flexible hose clamps. The high-pressure hoses, with their high-pressure resistant steel wire braided structure, possess excellent pressure resistance, meeting the high-pressure transmission requirements of both water and air circuits and ensuring safety during media transport. The quick-connect fittings at each pipe joint make connecting the high-pressure hoses to branch water pipes, branch air pipes, and connecting interfaces more convenient and efficient, significantly reducing installation and component replacement time and improving maintenance efficiency. The flexible hose clamps on the fixed support plate firmly secure the high-pressure hoses, preventing friction or collisions with other components due to shaking during equipment operation, reducing the risk of hose wear and loose connections, and also making the pipeline layout more organized and orderly.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 The present invention provides a technical solution: a wireless automatic water curtain spray frame, including an arc-shaped streamlined main frame 1, the surface of the arc-shaped streamlined main frame 1 is coated with an epoxy resin coating 2 after being treated with chromate, and a multi-port connector 3 is fixedly provided in the middle of the inner side of the arc-shaped streamlined main frame 1.

[0027] The two ends of the multi-port connector 3 are respectively provided with a main water pipe interface 4 and a main air duct interface 5. An electrical equipment interface 6 is provided in the middle of the outer surface of the multi-port connector 3. The electrical equipment interface 6 is a multi-core aviation plug.

[0028] When used in a mine working environment, the wireless automatic water curtain sprayer can be installed on the side or top of the main frame 1, depending on the space of the mine roadway. This effectively reduces the occupation of limited space in the mine and leaves more passage for mine operations. The external high-pressure water source enters the multi-connector 3 through the main water pipe interface 4, while the high-pressure air source enters the multi-connector 3 through the main air pipe interface 5. The quick-connect type ensures the sealing and convenience of the connection in the narrow space of the mine. The sealing structure of the multi-core aviation plug ensures the stability of the electrical connection in the humid and dusty environment of the mine, providing reliable protection for signal transmission. The epoxy resin coating 2 (treated with chromate as a base) on the surface of the curved streamlined main frame 1 forms a protective barrier to resist the erosion of moisture and dust in the mine. Combined with the streamlined design of the overall structure, it reduces airflow resistance in the mine roadway and ensures long-term stable operation of the equipment in the complex environment of the mine.

[0029] Four branch water pipe interfaces 7 are symmetrically distributed on the outer surface of the multi-port connector 3 near the main water pipe interface 4. Four branch air pipe interfaces 8 are symmetrically distributed on the outer surface of the multi-port connector 3 near the main air pipe interface 5. A controller 9 is installed inside the curved streamlined main frame 1. Four spherical hinge bases 10 are symmetrically distributed on the inner side of the curved streamlined main frame 1 with the multi-port connector 3 as the center. A spherical connecting shaft 11 is provided on the spherical hinge base 10. A spray head 12 is connected to the end of the spherical connecting shaft 11 away from the spherical hinge base 10. A fastening handle for locking the spherical connecting shaft 11 is provided on the outer surface of the spherical hinge base 10. 13. Two connecting interfaces 14 are symmetrically arranged on the outer surface of the spray head 12. Each branch water pipe interface 7 is connected to one of the connecting interfaces 14 of the corresponding spray head 12 through a high-pressure hose 15. Each branch air pipe interface 8 is connected to the other connecting interface 14 of the corresponding spray head 12 through a high-pressure hose 15. Both ends of the high-pressure hose 15 are equipped with quick-connect connectors that are compatible with the branch water pipe interface 7, the branch air pipe interface 8 and the connecting interface 14. The hose body adopts a high-pressure resistant steel wire braided layer structure. Fixed support plates 16 are symmetrically arranged on the side of the arc-shaped streamlined main frame 1. Elastic pipe clamps 17 are provided on the fixed support plates 16.

[0030] The water is distributed through the internal flow channel to four branch water pipe interfaces 7, and then the high-pressure hose 15 delivers the water flow to one of the corresponding connecting interfaces 14 of the spray head 12. After diversion, the water is sent through the four branch air pipe interfaces 8 to the other connecting interface 14 of the spray head 12 via the high-pressure hose 15. The high-pressure resistant steel wire braided layer structure of the high-pressure hose 15 ensures leak-free media transmission in the complex pipeline environment of the mine. The operator can adjust the spray direction of the spray head 12 according to the specific layout of the mine roadway by adjusting the ball connecting shaft 11 on the ball hinge base 10. The rotation range covers 0-90° to adapt to the dust suppression spray requirements of different mine areas. After adjustment, tighten the rotating handle 1. The ball connecting shaft 11 can be locked to prevent the spray head 12 from shifting angle due to vibration in the mine equipment environment, ensuring stable coverage of dust in the mine roadway. The controller 9 is connected to the dust sensor and control system in the mine through the electrical equipment interface 6 (multi-core aviation plug), receiving spray trigger signals such as dust concentration in the mine in real time, and controlling the on / off of the water / air circuit corresponding to the spray head 12 through the circuit according to the signal instructions, realizing automatic spray dust suppression or stopping. In addition, the elastic pipe clamp 17 fixes the high-pressure hose 15 in an orderly manner through the fixed support plate 16, preventing the pipeline from shaking and rubbing against other components due to equipment operation and personnel movement in the mine, thus preventing damage.

[0031] Working Principle: When used in a mine working environment, the curved, streamlined main frame 1 can be installed on the side or top depending on the space conditions of the mine roadway, effectively reducing the occupation of limited mine space and leaving more passage for mine operations. External high-pressure water enters the multi-way connector 3 through the main water pipe interface 4, and is distributed to four branch water pipe interfaces 7 via internal channels. The high-pressure hose 15 then delivers the water flow to one of the connecting interfaces 14 of the corresponding spray head 12. Simultaneously, high-pressure air enters the multi-way connector 3 through the main air duct interface 5, and then... After diversion, the fluid is delivered from four branch duct interfaces 8 to another connecting interface 14 of the spray head 12 via high-pressure hoses 15. The high-pressure resistant steel wire braided layer structure of the high-pressure hose 15 ensures leak-free media transmission in the complex pipeline environment of the mine. The quick-connect fittings ensure sealing and convenience of connection in the narrow space of the mine. Operators can adjust the spray direction of the spray head 12 according to the specific layout of the mine roadway by adjusting the ball connecting shaft 11 on the spherical hinge base 10. The rotation range covers 0-90° to adapt to the dust suppression spraying needs of different mine areas. After completion, tightening the locking handle 13 will lock the ball connecting shaft 11, preventing the spray head 12 from shifting angle due to vibration in the mine equipment environment, ensuring stable coverage of dust in the mine roadway. The controller 9 connects to the dust sensor and control system in the mine via the electrical equipment interface 6 (multi-core aviation plug), receiving spray trigger signals such as dust concentration in the mine in real time, and controlling the on / off of the water / air path corresponding to the spray head 12 through the circuit according to the signal instructions, realizing automatic spray dust suppression or stopping. The sealed structure of the multi-core aviation plug ensures that it can withstand the dampness in the mine. The stability of electrical connections in humid and dusty environments provides a reliable guarantee for signal transmission. In addition, the flexible pipe clamps 17 fix the high-pressure hoses 15 in an orderly manner through the fixed support plates 16, preventing the pipeline from shaking and rubbing against other components due to equipment operation and personnel movement in the mine. The epoxy resin coating 2 (treated with chromate as a base) on the surface of the arc-shaped streamlined main frame 1 forms a protective barrier to resist the erosion of moisture and dust in the mine. Combined with the streamlined design of the overall structure, it reduces airflow resistance in the mine roadway, ensuring long-term stable operation of the equipment in the complex environment of the mine.
