Description

Technical Field

[0001] The utility model relates to the technical field of chimney blasting protection, and more particularly to a dust reduction type chimney blasting protection net structure. Background Art

[0002] With the development of urban scale and industry, many factories have relocated out of urban areas, and the chimneys originally attached to the factories have also been abandoned. When demolishing abandoned chimneys, directional blasting is generally used. During blasting, a cut is blasted at the root of the chimney, causing the chimney to lose support on one side and collapse in a predetermined direction, achieving rapid demolition. However, during demolition, the collapse of the chimney will cause a large amount of dust to be raised, affecting the lives of surrounding buildings and people. Therefore, people have designed an artificial water pool dust reduction device for chimney blasting, such as the one disclosed in Chinese patent application number 201620266418.1, or a dust reduction device for chimney folding blasting demolition, such as the one disclosed in Chinese patent application number 202120549034.1. To improve the dust reduction effect, the dust reduction device should be as close as possible to the area where the chimney collapses. However, during blasting, the direction of chimney collapse is also affected by multiple factors such as wind load and the chimney's own structure. The direction of chimney collapse can generally only be controlled within a certain range. If the dust reduction device is too close to the chimney collapse area, it is easily damaged by the chimney.

A branch pipe 12 connected to the water bag 4 located below it is provided at the bottom of each water tank 10, and a relay pump 13 is provided between the water tank 10 and the intermediate connecting pipe 11; a protective net 14 is provided, and a protective net 14 arranged around the chimney is provided between two adjacent guard rings 1, and the protective net 14 is fastened to the guard ring 1 with wire.

[0034] In this dust suppression chimney blasting protection net structure, multiple guard rings 1 are installed on the periphery of the chimney 30, and multiple water bags 4 are arranged between two adjacent guard rings 1 to form a multi-layer water bag 4. The water bags 4 between two adjacent layers are arranged in a staggered manner. When the chimney 30 is blasted and collapses to the ground, the water bags 4 will burst under the impact force, causing the water in the water bags 4 to splash out, and the dust generated by the collapse of the chimney 30 will be wetted and dust removed, thereby reducing the amount of dust and narrowing the diffusion range, achieving a very good dust suppression effect.

[0035] A protective net 14 is provided on the plurality of retaining rings 1. When the bottom of the chimney 30 is subjected to gunpowder blasting, the protective net 14 can block the blasted rubble and bricks, reduce the speed and height of the rubble and bricks flying, and reduce the distance the rubble and bricks are blown away, thereby avoiding damage to buildings and residents around the chimney and ensuring the safety of the chimney 30 blasting operation. At the same time, the water bag 4 near the bottom of the chimney 30 is ruptured by the impact of the explosion, and the water in the water bag 4 splashes out to reduce dust at the blasted location at the bottom of the chimney 30.

[0036] In this dust reduction chimney blasting protection net structure, the water supply device 7 supplies water to the water tank 10 through the water supply pipe 8 and the water supply pump 9. Since the height of the chimney 30 is several tens of meters, multiple water tanks 10 and relay pumps 13 are required to be used in conjunction to transport water to the top of the chimney 30. The water in the water tank 10 is supplied to the water bag 4 located below through the branch pipe 12; after the water bag 4 and the water tank 10 are filled with water, the relay pump 13 can be removed to avoid damage to the relay pump 13 during the blasting operation.

[0037] In a preferred embodiment of the present invention, the retainer 1 includes two semicircular rings 21, each of which is provided with a splicing sleeve 15 and a splicing rod 16 at its two ends. The two semicircular rings cooperate with the splicing sleeve 15 and the splicing rod 16 to form a circular ring. In this embodiment, the retainer 1 is formed by splicing the two semicircular rings 21, each of which is provided with a splicing sleeve 15 and a splicing rod 16 at its two ends. The splicing sleeve 15 and the splicing rod 16 cooperate to form the two semicircular rings 21 into a circular retainer 1, which is convenient for assembly and disassembly, simple to operate, and quick to assemble.

[0038] A preferred embodiment of the present utility model is that a locking sleeve 17 is rotatably sleeved on the plug rod 16 and threadedly connected to the outer wall of the plug sleeve 15, and one end of the inner wall of the locking sleeve 17 is provided with a limiting step, and the plug rod 16 is threadedly connected with a limiting nut 18 adapted to the limiting step; in this embodiment, the locking sleeve 17 is rotatably sleeved on the plug rod 16, and the locking sleeve 17 is limited by the limiting nut 18 to prevent the locking sleeve 17 from sliding on the plug rod 16. After the plug rod 16 is inserted into the plug sleeve 15, the plug rod 16 and the plug sleeve 15 are threadedly connected by the locking sleeve 17.

[0039] In this embodiment, the connection assembly 2 includes a bracket 19 connected to the chimney via expansion screws. A clamp structure 20 for fixing the retaining ring 1 is provided on the bracket 19. The bracket 19 is an L-shaped plate structure.

[0040] In a preferred embodiment of the present invention, the retainer 1 is provided with a plurality of screw holes evenly spaced, and the sliding sleeve 5 is provided with locking screws 22 adapted to the screw holes. The locking screws 22 secure the sliding sleeve 5 on the retainer 1, preventing the water bladders 4 from shifting and maintaining an even arrangement of the plurality of water bladders 4 on the retainer 1.

[0041] In a preferred embodiment of the present invention, the retainer 1 is provided with a plurality of evenly spaced connecting sleeves 23, which are arranged vertically. A partition is provided within the connecting sleeves 23. The upper and lower ends of the support rods 3 are adapted to fit within the connecting sleeves 23. A pin is threadedly connected to the outer wall of the connecting sleeves 23 and is provided through a pin hole at the end of the support rod 3. The support rods 3 can be quickly plugged into the connecting sleeves 23 and then positioned with the pin. The multiple support rods 3 provide reliable support for two adjacent retainers 1.

[0042] In a preferred embodiment of the present invention, the bottom end of the water tank 10 is connected to a spray pipe 24, which extends spirally around the chimney 30. The spray pipe 24 is fixedly connected to the outer wall of the chimney 30 via a support. The spray pipe 24 is provided with a nozzle 25. The top of the spray pipe 24 is provided with a solenoid valve 26, which is electrically connected to a controller. The solenoid valve 26 can be controlled by the controller to open, causing the water tank 10 to supply water to the nozzle 25 on the spray pipe 24. The water tank 10 is positioned at a high position, and the water pressure within the water tank 10 can cause the nozzle 25 to spray water mist. In this embodiment, when the chimney 30 is blasted, the spray pipe 24 can be used to wet the area around the chimney 30, including the protective net 14, to increase the humidity in the air, thereby effectively suppressing the spread of dust when the chimney 30 collapses.

[0043] In this embodiment, a stop valve 27 is provided on the branch pipe 12, and a one-way valve 28 is provided at the water inlet joint 6. Opening the stop valve 27 allows the water in the water tank 10 to flow from the branch pipe 12 into the water bag 4 to fill the water bag 4. The one-way valve 28 is provided to prevent the water in the water bag 4 from flowing out.

[0044] In this embodiment, a liquid level sensor 29 is provided in the water tank 10. The liquid level sensor 29 is electrically connected to the power supply switch of the relay pump 13 and the water supply pump 9, and can automatically control the power supply switch to be disconnected or turned off, thereby controlling whether the relay pump 13 is working; in actual use, each water tank 10 is filled with water in turn through the relay pump 13 and the intermediate connecting pipe 11 until the liquid level in the water tank 10 reaches the set value.

[0045] Working principle:

[0046] During operation, the water bag 4 is installed on two adjacent retaining rings 1, and water is supplied to the water tank 10 through the water supply pipe 8 and the water supply pump 9. The water is then transported to each water tank 10 in sequence through the intermediate pipe 11 by the relay pump 13. The top of the intermediate pipe 11 is connected to the top inner cavity of the water tank 10. At the same time, the stop valve 27 is opened to inject water into the water bag 4 from the water tank 10. The spray pipe 24 is arranged in a spiral extending around the chimney 30. The protective net 14 is installed on the retaining ring 1 outside the chimney 30 and is tied tightly with wire. The protective net 14 is a wire mesh structure.

[0047] Before the chimney is blasted, the solenoid valve 26 is opened by the controller, so that the water tank 10 is connected with the spray pipe 24 and the nozzle 25, and water is supplied to the nozzle 25, so that the nozzle 25 sprays water mist to wet the surrounding area;

[0048] After the chimney 30 collapses, the water bag 4 and the water tank 10 burst due to the impact force, and the water in the water bag 4 and the water tank 10 splashes out to reduce the dust raised by the collapse of the chimney 30.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
