Description

Technical Field

[0001] The present invention relates to the technology of roadway dust reduction, and particularly to a retractable roadway dust-proof water curtain generating device. Background Art

[0002] Coal dust is solid particles that fly into the ambient air during the processes of coal mining, transportation, transfer, storage, and processing. It is one of the five major natural disasters in mines (gas, coal dust, water, fire, roof). The main hazards of coal dust are in three aspects: First, the harm to the human body. If a person inhales a large amount of coal dust into the lungs for a long time, he may suffer from pneumoconiosis, which is a relatively harmful miner occupational disease at present. Second, the hazard of coal dust explosion. Coal dust explosion is one of the serious disasters in coal mines, which seriously threatens the safety of mine shafts. Third, environmental pollution. Currently, coal dust pollution has become the main factor of air pollution in the main coal-producing areas of our country. To minimize the coal dust concentration in the mining face and other working places and ensure the physical and mental health of all underground workers in the mine and the safe production of the mine, comprehensive dust prevention measures must be taken, that is, effective dust prevention measures must be implemented for each link. Moreover, the "Coal Mine Safety Regulations" stipulate the coal mine dust concentration: Coal mining enterprises must strengthen the prevention and management of occupational hazards, do a good job in the occupational health and labor protection work of the working places. Take effective measures to control the hazards of dust and poison, ensure that the working places meet the national occupational health standards. In order to prevent the diffusion of coal dust in the coal mining, tunneling and other working faces, the coal mine operation regulations stipulate that a dust-proof water curtain should be set up in the roadway.

[0003] Chinese Patent with the application number 201621324436.7 discloses a dust-proof water curtain device for coal mine roadways. The frame is in an inverted U shape. The cross bar of the frame is formed by a first stainless steel pipe and a second stainless steel pipe. The first stainless steel pipe and the second stainless steel pipe are connected and communicated through a high-pressure hose. The high-pressure hose is connected and communicated with a static pressure water pipe through a three-way piece. One end of the cross bar is provided with a vertically arranged third stainless steel pipe, and the other end of the cross bar is provided with a vertically arranged fourth stainless steel pipe. Both the third stainless steel pipe and the fourth stainless steel pipe are connected and communicated with the cross bar. Three sector nozzles are evenly arranged on the cross bar, and two sector nozzles are respectively arranged on the third stainless steel pipe and the fourth stainless steel pipe. The sector nozzles spray water mist to form a water curtain covering the cross section of the coal mine roadway. By arranging 7 sector nozzles and arranging them at 30° against the wind, while reducing the water consumption, the whole cross section of the coal mine roadway can be covered, and the spray dust reduction effect is significantly enhanced. However, when implementing this patent, during the process of the water mist nozzle spraying water mist, as the distance increases, the intensity of the water mist gradually weakens, resulting in a lower density of the water mist in the middle position, so that part of the dust escapes from the center position of the water curtain. At the same time, when there is wind in the roadway, at this time the dust has a certain wind speed, and the dust with a certain speed will break through the water curtain and escape, resulting in a poor blocking effect of the water curtain on the dust.

[0017] Compared with the prior art, a retractable roadway dust-proof water curtain generating device provided by the present invention has the following beneficial effects:

[0018] (1) By supplying water into the water inlet arched pipe and the arched hose, then the water is supplied through the first water mist nozzles on the water inlet arched pipe and the arched hose, and then the first water mist nozzles spray out water mist. At this time, a circular water mist water curtain is generated, so that the water mist sprayed out by each first water mist nozzle gathers at the center position of the circle when it decays at the end. At this time, because the area of the center position is small, the generated water curtain has a large blocking force, which is beneficial to blocking dust.

[0019] (2) When the wind speed in the roadway increases, by monitoring the wind speed in real time, a water curtain is generated at the central position of the water curtain by activating the water curtain strengthening mechanism, thereby enhancing the weak water curtain in the center of the roadway and further improving the dust blocking effect of the water curtain.

[0020] (3) When the wind speed in the roadway gradually increases, it can drive the adjustment pipe in the water curtain strengthening mechanism to move. The adjustment pipe drives the third water mist nozzle to move, increasing the range of the enhanced water curtain at the central position of the roadway. Thus, as the wind speed increases, the generation range of the enhanced water curtain at the central position is gradually enhanced, further improving the blocking of dust in the roadway.

[0021] (4) The dust blocked and settled by the water curtain is collected by the collecting plate, and then discharged into the collecting box through the discharge chute for collection. When a trolley or pedestrian passes through the roadway, at the same time, the first electric telescopic rod drives the arched hose to move, opening the passage. At the same time, the arched hose drives the cleaning plate to move through the connecting block and the connecting rod. The cleaning plate clears the settled dust on the collecting plate into the discharge chute, and then enters the collecting box through the discharge chute for collection. Thus, the settled dust soluble in water on the collecting plate is cleared into the discharge chute for collection, realizing the collection and cleaning of the dust blocked by the water curtain and preventing the pollution of the roadway caused by the dust soluble in water.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] Please refer to Figures 1 - 7 , a retractable roadway dust-proof water curtain generating device, including an arch frame 1, an inlet arch pipe 2 fixedly connected inside the arch frame 1, both ends of the inlet arch pipe 2 are fixedly connected with arch-shaped hoses 3 through hoses, the outer surfaces of the inlet arch pipe 2 and the arch-shaped hoses 3 are both fixedly connected with first water mist nozzles 4, the outer surface of the arch-shaped hose 3 is fixedly connected with a first electric telescopic rod 5 fixedly connected with the arch frame 1 through a connecting block, the outer surface of the arch-shaped hose 3 is fixedly connected with a soft cloth 6 fixedly connected with the arch frame 1, a water curtain strengthening mechanism connected to the inlet arch pipe 2 is arranged inside the arch frame 1, and a cleaning mechanism is arranged on the arch frame 1.

[0035] By digging an installation pit in the coal mine and then installing the arch frame 1 in the installation pit, and at the same time leveling the cleaning mechanism with the roadway ground. When the wind speed in the coal mine roadway is small, water is supplied to the water inlet arch pipe 2 through an external water pipe at this time. Then, the water inlet arch pipe 2 supplies water to the arch hose 3 through a hose. Subsequently, water is supplied to the first water mist nozzle 4 on the water inlet arch pipe 2 and the arch hose 3. Then, the first water mist nozzle 4 sprays water mist outwards. At this time, a circular water mist curtain is generated, so that the water mist sprayed by each first water mist nozzle 4 gathers at the center position of the circle when it attenuates at the end. At this time, since the area of the center position is small, the generated water curtain has a large blocking force, which is beneficial to blocking dust. When a vehicle passes through the roadway, at this time, the first electric telescopic rod 5 drives the arch hose 3 to move and contract to both sides. At this time, the soft cloth 6 folds, opening the bottom passage to facilitate the vehicle to pass through the roadway. At the same time, during the opening process, the first water mist nozzle 4 on the arch hose 3 continues to spray water mist to form a water curtain, improving the blocking of dust. At the same time, when the wind speed in the roadway is large, at this time, the dust has a certain speed. Since the water curtain generated at the center position attenuates during the spraying process, the dust with a certain speed will escape from the center position of the water curtain on the water curtain. At this time, it enters the center position of the circle through the water curtain strengthening mechanism to form a water curtain, so that a stronger water curtain is formed at the center position, enhancing the water curtain and further improving the blocking effect of the water curtain on the dust in the roadway.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, please refer to Figures 2 - 7 As shown, the water curtain strengthening mechanism includes a second electric telescopic rod 11 fixedly connected to the arch frame 1. The bottom end of the second electric telescopic rod 11 is fixedly connected with a mounting plate 12. A wind speed sensor 13 is fixedly connected to the bottom of the mounting plate 12. The wind speed sensor 13 is a prior art, so no more details will be described here. A first mounting pipe 14 is rotatably connected to the mounting plate 12. One end of the first mounting pipe 14 is fixedly connected with a mounting box 15. A plurality of second mounting pipes 16 are fixedly connected to the mounting box 15. A first water supply pipe 17 fixedly connected to the second mounting pipe 16 is fixedly connected to the first mounting pipe 14. The outer surface of the first water supply pipe 17 is fixedly connected with a second water supply pipe 18 fixedly connected to the first mounting pipe 14 through a pipe. A plurality of second water mist nozzles 19 fixedly connected to the first mounting pipe 14 are fixedly connected to the outer surface of the second water supply pipe 18. A plurality of the second water mist nozzles 19 located on both sides of the first mounting pipe 14 are both inclined and symmetrically arranged, so that when the second water mist nozzles 19 spray water mist, the second water mist nozzles 19 on both sides spray water mist forward and backward respectively. A transmission mechanism is arranged on the outer surface of the first mounting pipe 14;

[0038] The transmission mechanism includes a transmission motor 31 fixedly connected to the mounting plate 12. The transmission motor 31 is controlled by a PLC programming program to control the transmission motor 31 to rotate forward and backward and to rotate at an angle. The output end of the transmission motor 31 is fixedly connected to a transmission shaft 32 through a coupling. A first gear 33 is fixedly sleeved on the outer surface of the transmission shaft 32. A second gear 34 fixedly sleeved on the outer surface of the first gear 33 is meshedly connected to the first mounting tube 14. The transmission motor 31 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the first mounting tube 14 to rotate through the first gear 33 and the second gear 34.

[0039] The outer surface of the first installation pipe 14 is provided with a water supply mechanism connected to the water inlet arch pipe 2, and the water supply mechanism includes a connecting pipe 41 rotatably connected to the first installation pipe 14, one end of the connecting pipe 41 is fixedly connected to a water inlet hose 42 fixedly connected to the water inlet arch pipe 2, and an electromagnetic valve is provided on the water inlet hose 42. By opening the electromagnetic valve on the water inlet hose 42, water is then supplied to the water inlet hose 42 through the water inlet arch pipe 2, and the water inlet hose 42 supplies water to the first installation pipe 14 through the connecting pipe 41;

[0040] The mounting plate 12 is driven downward by the second electric telescopic rod 11, and the mounting plate 12 drives the wind speed sensor 13 to monitor the wind speed at the center position. When the wind speed sensor 13 detects that the wind speed at the center position reaches a certain level, the level is set by the staff according to the actual situation. At this time, the first mounting pipe 14 is driven to rotate by the transmission mechanism, and the first mounting pipe 14 drives the mounting box 15 and the second mounting pipe 16. At the same time, the water supply mechanism supplies water to the first mounting pipe 14, and the first mounting pipe 14 supplies water to the second water supply pipe 18 through the first water supply pipe 17 and the pipeline. The second water supply pipe 18 supplies water to the second water mist nozzle 19, and the second water mist nozzle 19 sprays water mist. At the same time, the transmission mechanism drives the first mounting pipe 14 and the mounting box 15 to rotate, and the mounting box 15 drives multiple second mounting pipes 16 and second water mist nozzles 19 to rotate, and the second water mist nozzles 19 spray water mist outward, thereby forming a water curtain at the center position, further enhancing the strength of the water curtain to block dust.

[0041] A spray adjustment mechanism connected to the first water supply pipe 17 is arranged inside the first installation pipe 14. The spray adjustment mechanism includes a third electric telescopic rod 21 fixedly connected to the second installation pipe 16. One end of the third electric telescopic rod 21 is fixedly connected with an adjustment pipe 22 through a connecting block. A sealing rubber ring 23 slidably connected to the adjustment pipe 22 is fixedly connected to the outer surface of the first water supply pipe 17. A plurality of third water mist nozzles 24 are fixedly connected to the outer surface of the adjustment pipe 22. The plurality of third water mist nozzles 24 on both sides of the adjustment pipe 22 are inclined. At the same time, it satisfies the opposite inclination design of the third water mist nozzles 24 on both sides, so that when the third water mist nozzles 24 spray water mist, the third water mist nozzles 24 on both sides spray water mist forward and backward respectively;

[0042] When the wind speed sensor 13 monitors an increase in the wind speed in the roadway, at this time, according to the increased intensity, the third electric telescopic rod 21 drives the adjustment pipe 22 to move outwards from the second installation pipe 16. During the outward movement of the adjustment pipe 22, at this time, the sealing rubber ring 23 on the first water supply pipe 17 moves to one side of the adjustment pipe 22. At this time, water begins to enter the adjustment pipe 22 from one end of the first water supply pipe 17, and then water supply is carried out inside the adjustment pipe 22. The adjustment pipe 22 ejects through a plurality of third water mist nozzles 24 on its surface to form a water curtain, thereby realizing that as the wind speed increases, the generation range of the enhanced water curtain at the central position is gradually enhanced, and further improving the blocking of dust in the roadway.

[0043] Embodiment Three

[0044] On the basis of Embodiment One, please refer to Figure 1 and Figure 2 As shown, the cleaning mechanism includes a collecting plate 51 fixedly connected to the arch frame 1. A retaining strip 52 is fixedly connected to the top of the collecting plate 51. A cleaning plate 53 is slidably connected to the top of the collecting plate 51. The cleaning plate 53 is fixedly connected to the arch-shaped hose 3 through a connecting rod and a connecting block. A discharge slot 54 is formed on the collecting plate 51. A collecting box 55 is fixedly connected to the bottom of the collecting plate 51. A collecting pipe is fixedly connected to the collecting box 55;

[0045] The collecting plate 51 collects the dust blocked and settled by the water curtain, and then discharges it into the collecting box 55 through the discharge slot 54 for collection. When a trolley or pedestrian passes through the roadway, at this time, the first electric telescopic rod 5 drives the arch-shaped hose 3 to move simultaneously to open the passage. At the same time, the arch-shaped hose 3 drives the cleaning plate 53 to move through the connecting block and the connecting rod. The cleaning plate 53 cleans the dust settled on the collecting plate into the discharge slot 54, and then enters the collecting box 55 through the discharge slot 54 for collection, thereby cleaning the dust dissolved in water on the collecting plate 51 into the discharge slot 54 for collection, realizing the collection and cleaning of the dust blocked by the water curtain, and preventing the dust dissolved in water from polluting the roadway.

[0046] Working principle: An installation pit is dug in the coal mine, and then the arched frame 1 is installed in the installation pit. At the same time, the cleaning mechanism is level with the roadway ground. When the wind speed in the coal mine roadway is relatively low, water is supplied to the water inlet arched pipe 2 through an external water pipe at this time. Then, the water inlet arched pipe 2 supplies water to the arched hose 3 through a hose. Subsequently, water is supplied to the first water mist nozzles 4 on the water inlet arched pipe 2 and the arched hose 3. Then, the first water mist nozzles 4 spray water mist outwards. At this time, a circular water mist curtain is generated, so that the water mist sprayed by each first water mist nozzle 4 gathers at the center position of the circle when it attenuates at the end. At this time, because the area of the center position is small, the generated water curtain has a large blocking force, which is beneficial to blocking dust. When a vehicle passes through the roadway, at this time, the first electric telescopic rod 5 drives the arched hose 3 to move and contract to both sides. At this time, the soft cloth 6 is folded, and the bottom passage is opened to facilitate the vehicle to pass through the roadway. At the same time, during the opening process, the first water mist nozzles 4 on the arched hose 3 continue to spray water mist to form a water curtain, further improving the blocking of dust. At the same time, when the wind speed in the roadway is relatively high, at this time, the dust has a certain speed. Because the water curtain formed at the center position attenuates during the spraying process, the dust with a certain speed will escape from the water curtain at the center position of the water curtain. At this time, it enters the center position of the circle through the water curtain strengthening mechanism to form a water curtain, so that a stronger water curtain is formed at the center position, enhancing the water curtain and further improving the blocking effect of the water curtain on the roadway dust.

[0047] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
