[0002] A coal storage yard is a designated area for storing coal, typically located near coal-fired power plants, steel mills, or other industrial facilities that require large quantities of coal. The primary function of a coal storage yard is to store coal for loading and transportation when needed.

[0003] A search revealed a Chinese patent (CN205199195U) disclosing a dust suppression spraying device for open-air coal storage yards. The device includes a base, a control cabinet, and power distribution cables. A traction device is located on the right side of the base. A water tank is mounted on top of the base, connected to a booster pump, which is connected to a generator via power distribution cables. This utility model's dust suppression spraying device for open-air coal storage yards can be mounted on a mobile vehicle or manually pushed; it can be manually controlled or wirelessly remote controlled. It is convenient to use and simple to operate, enabling dust suppression through water spraying in coal storage yards, reducing investment costs, and ensuring clean production at ports.

[0004] While the above solutions can achieve dust suppression by watering coal stockpiles, reduce investment costs, and ensure clean production at ports, the spray dust suppression devices in the aforementioned patents have limited spray range. Even when placed on mobile locomotives or manually pushed, repeated movement is still required to spray the entire stockpile area, making the operation complex and the dust suppression efficiency low. Therefore, we provide a rapid dust suppression watering device for coal stockpiles to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid dust suppression and water spraying device for coal stockpiles, comprising a water supply system body and a protective shell. The inner wall of the protective shell is rotatably connected to a planar worm gear via a positioning shaft. One side of the planar worm gear is rotatably connected to a force-applying linkage rod. One end of the force-applying linkage rod is rotatably connected to a power swing rod. One end of the power swing rod is fixedly connected to the outer circumferential surface of a drive rod. The outer circumferential surface of the drive rod is rotatably connected to the inner wall of the protective shell. One end of the drive rod is fixedly connected to a U-shaped mounting frame. The U-shaped mounting frame is fitted with a mounting column via locking bolts. One end of the mounting column is fitted with a spray nozzle.

[0007] Preferably, the nozzle is connected to the main body of the water supply system via a telescopic hose.

[0022] 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.

[0023] This utility model provides a technical solution for a rapid dust suppression and water spraying device for coal stockpiles.

[0024] Please see Figure 1 , Figure 4 and Figure 5 The system includes a main water supply system 1 and a protective outer shell 2. The main water supply system 1 is constructed in the coal storage yard. Water supply pipelines are laid underground. Four to six water spray gun stations and control systems are installed on both sides of each coal stack. A 2-cubic-meter water storage tank is installed below each spray gun station. The water tank is equipped with a float level gauge and an inlet valve. When the water tank is full, the inlet valve closes to stop water supply. The water tank provides water to the spray gun stations above. An environmental monitoring system is installed near each stack to provide information support for the start and stop of the spray gun stations. The water supply pipeline supplies water to the water storage tank of the spray gun station. A high-pressure submersible pump is installed in the water storage tank to provide pressure for the sprinklers, so that water is sprayed out from the nozzles 11.

[0025] Please see Figure 1 , Figure 4 and Figure 5 The existing centralized water supply and pressure supply mode will be modified from the original 4-6 spray guns to the ability to open a large number or even all of the spray guns in the stockyard. When there is a lot of dust in the stockyard, opening all the spray guns can quickly achieve the dust reduction effect. An environmental monitoring system will be added near each stack. When there is a lot of coal dust in this area, the environmental monitoring system will send a signal. When the control system receives the signal, it will open the spray gun station near this stack to spray water and reduce dust point by point.

[0026] Please see Figure 1 , Figure 4 and Figure 5The spray gun station consists of a spray gun station insulation box, pressure relief valve, small water storage tank, level gauge, electric valve, water inlet pipe, spray gun station foundation, sprinkler water supply pipe, high-pressure centrifugal pump and other related equipment. Three water supply centrifugal pumps are installed, with two in use and one as a backup. Each pump has a power of 132KW. Each spray gun station is equipped with one high-pressure centrifugal pump with a power of 30KW. The small water storage tank is made of reinforced concrete and buried underground to prevent the water storage tank from freezing in winter.

[0027] Please see Figure 1 , Figure 4 and Figure 5 The total water storage tank has a capacity of approximately 3000 cubic meters. It is equipped with corresponding auxiliary equipment, including filters, overflow pipes, ventilation holes, level gauges, electric valves, a water inlet pipe, and butterfly valves. When the small on-site water tank needs water supply, a centrifugal pump is activated. The electric valve automatically closes when the water level in the tank reaches a high level. The water storage tank is equipped with an overflow outlet and a drain pipe. When the water level is high, water overflows from the overflow outlet; when the tank needs to be emptied, water is drained from the drain pipe. The water storage tank is equipped with a level gauge. When the water level is low, a signal is transmitted to the PLC, which controls the electric valve to open; when the water level is high, the PLC controls the electric valve to close.

[0028] Please see Figure 4 and Figure 5 The butterfly valve is a manual maintenance valve. A filter is installed before the water supply centrifugal pump to prevent large foreign objects from entering the pump system and damaging the pump. A flow meter is installed on the pump outlet pipe to measure the water volume. The outlet pipe is connected to the underground water supply pipeline on site. The pipeline diameter is DN300 and a dual-line water supply mode is adopted.

[0029] Please see Figure 1 , Figure 4 and Figure 5 The main body of the water supply system 1 is a known technology, and this application will not elaborate on its appearance or components.

[0030] Please see Figure 1 and Figure 2 The inner wall of the protective housing 2 is rotatably connected to a one-way worm gear 14. The protective housing 2 can effectively support the one-way worm gear 14 and apply a control effect to ensure that the one-way worm gear 14 can rotate in place. A DC motor 13 is fixedly connected to one side of the protective housing 2. The output shaft of the DC motor 13 is fixedly connected to the one-way worm gear 14. The purpose of setting the DC motor 13 is to effectively provide sufficient power support for the rotation of the one-way worm gear 14. The DC motor 13 is existing known technology, and will not be described in detail.

[0031] Please see Figure 2The thread on the outer circumferential surface of the one-way worm 14 meshes with the teeth on the outer circumferential surface of the planar worm wheel 4. The tight fit between the one-way worm 14 and the planar worm wheel 4 can effectively achieve the force transmission effect and has a self-locking effect, ensuring the stability of subsequent components after movement.

[0032] Please see Figure 2 The top of the main body 1 of the water supply system is fixedly connected to a protective shell 2. The inner wall of the protective shell 2 is rotatably connected to a planar worm gear 4 through a positioning shaft 3. The purpose of setting the positioning shaft 3 is to make the planar worm gear 4 rotate around the positioning shaft 3.

[0033] Please see Figure 2 One side of the planar worm gear 4 is rotatably connected to a force-applying linkage rod 5, and one end of the force-applying linkage rod 5 is rotatably connected to a power swing rod 6. The close cooperation between the planar worm gear 4, the force-applying linkage rod 5 and the power swing rod 6 allows the planar worm gear 4 to drive the power swing rod 6 to move through the force-applying linkage rod 5 when the power swing rod 6 remains stable.

[0034] Please see Figure 2 and Figure 3 One end of the power swing arm 6 is fixedly connected to the outer circumferential surface of the drive rod 7. The power swing arm 6 and the drive rod 7 maintain a linkage effect. The outer circumferential surface of the drive rod 7 is rotatably connected to the inner wall of the protective shell 2. The drive rod 7 is controlled by the protective shell 2, so that the drive rod 7 can only rotate in place, thus ensuring the stability of the power swing arm 6.

[0035] Please see Figure 2 and Figure 3 One end of the drive rod 7 is fixedly connected to a U-shaped mounting bracket 8. The drive rod 7 and the U-shaped mounting bracket 8 maintain a linkage effect. The U-shaped mounting bracket 8 is equipped with a mounting column 10 by locking bolts 9. The purpose of setting locking bolts 9 is to adjust the tilt angle of the mounting column 10 and to facilitate operation by the staff.

[0036] Please see Figure 1 and Figure 3 A nozzle 11 is installed at one end of the mounting column 10. The mounting column 10 can drive the nozzle 11 to swing. The nozzle 11 is connected to the main body of the water supply system 1 through the telescopic hose 12. The purpose of setting the telescopic hose 12 is to allow the water in the main body of the water supply system 1 to smoothly enter the nozzle 11, so as to achieve the purpose of water spraying and dust suppression.

[0037] Working principle: During use, the water in the main body 1 of the water supply system is conveyed through the telescopic hose 12 into the nozzle 11, and then sprayed out from the nozzle 11 to achieve the purpose of rapid dust suppression and watering. During the watering process of the nozzle 11, the DC motor 13 can be started according to the usage situation, so that the one-way worm gear 14 rotates in place in the protective shell 2, thereby driving the planar worm wheel 4 to rotate around the positioning shaft 3. At this time, the power swing rod 6 connected with the force linkage rod 5 will be restricted by the protective shell 2 through the drive rod 7. Therefore, the planar worm wheel 4 can drive the power swing rod 6 to swing through the force linkage rod 5, so that the drive rod 7 moves synchronously, thereby driving the U-shaped mounting frame 8 to move. Then, through the locking bolt 9, the nozzle 11 connected with the mounting column 10 swings synchronously, thereby effectively increasing the dust suppression range and improving the on-site use effect.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
