Description

Technical Field

[0001] The invention relates to the technical field of road engineering, and in particular to an automatic spray dust reduction and environmental protection system for highway construction. Background Art

[0002] Highway construction generates a large amount of dust, which diffuses in the air. When inhaled by humans, it can cause respiratory diseases and cause great harm to the environment. At present, in order to reduce the dust content in the air, improve the air quality at the construction site, and protect the environment, dust suppression vehicles are used to spray liquid into the air, or fog piles are deployed to spray water mist into the air at high pressure.

[0003] Dust suppression vehicles are large in size and require a certain amount of on-site space for activities. When the construction road is narrow and the space is insufficient, it is difficult for the dust suppression vehicle to reach the designated location. Fog piles solve this problem better, but the existing fog piles are relatively high and large in size. When the construction of a certain section of road is completed, the fog piles need to be disassembled and transferred to the next construction section. Due to the height of the fog piles, it is not convenient to disassemble and carry them. When the fog piles fail and need to be repaired, it may also be necessary to disassemble the fog piles or climb up to repair them. In addition, depending on the dust situation on site, the fog piles may need to spray the surrounding environment 360° without dead angles, or they may only spray back and forth within a certain range. Therefore, in order to save water resources, the spraying range of the fog piles needs to have higher flexibility and adjustability. Summary of the invention

When the nozzle 17 rotates clockwise toward the turntable 8, the water sprayed from the nozzle 17 can impact and rotate to the impact plate 9 directly facing the nozzle 17. When the nozzle 2 19 rotates counterclockwise toward the turntable 8, the water sprayed from the nozzle 2 19 can impact and rotate to the impact plate 9 directly facing the nozzle 2 19.

[0034] See attached Figure 1 and attached Figure 2 The outer wall of the bottom end of the fixed pile 1 is provided with a water pump 20, and the water outlet of the water pump 20 is provided with a water outlet pipe 1 21 that passes through the side wall of the fixed pile 1 and extends into the floating chamber 3. The end of the water outlet pipe 1 21 away from the water pump 2 20 penetrates the movable pile 5 from the bottom and then extends to the top of the movable pile 5. The end of the water outlet pipe 1 21 away from the water pump 2 20 is provided with a water inlet pipe 3 22 and a water inlet pipe 4 23 that are connected to the annular channel 1 14 and the annular channel 2 15 respectively. The water inlet pipe 3 22 and the water inlet pipe 4 23 extend from the movable pile 5 into the spray block 6. The water inlet pipe 3 22 and the water inlet pipe 4 23 are respectively provided with a solenoid valve 2 24 and a solenoid valve 3 25, and the water inlet of the water pump 2 20 is provided with a water inlet pipe 5 26. The water inlet pipe 5 26 of this embodiment is provided with a water inlet pipe 6 40 connected with the water inlet pipe 5 26, the water inlet pipe 6 40 is provided with a solenoid valve 4 41, the end of the water inlet pipe 6 40 away from the water inlet pipe 5 26 passes through the side wall of the bottom end of the fixed pile 1 and is connected with the floating chamber 3, and the end of the water inlet pipe 5 26 away from the water inlet pipe 6 40 and the water pump 2 20 is provided with a solenoid valve 5 42. The function of the water inlet pipe 6 40 is to pump the water in the floating chamber 3 out of the spray block 6 through the water inlet pipe 6 40, thereby lowering the water level in the floating chamber 3 and lowering the height of the movable pile 5.

[0035] See attached Figure 3 and attached Figure 6 , a plurality of nozzles 3 27 equidistantly arranged along the circumferential direction of the spray block 6 are provided in the spray block 6, and the nozzles 3 27 are arranged on the outer side of the annular pressure plate 13, and the spray ports of the nozzles 3 27 pass through the outer wall of the spray block 6. A drainage assembly is provided on the bottom surface of the driving chamber 7, and a connecting hose 30 is provided between the bottom end of the drainage assembly and each nozzle 3 27. The drainage assembly includes a water outlet pipe 28 which is arranged at the center of the bottom surface of the driving chamber 7 and extends toward the ground, and the water outlet pipe 28 is connected to the driving chamber 7. The water outlet pipe 1 21 is provided with a water outlet pipe 3 29 which is connected to the water outlet pipe 1 21 and extends into the spray block 6 after passing through the top of the movable pile 5, and the end of the water outlet pipe 3 29 away from the water outlet pipe 1 21 is connected to the water outlet pipe 2 28, and the end of the water outlet pipe 3 29 close to the water outlet pipe 2 28 is inclined toward the flow direction of water in the water outlet pipe 2 28. See attached Figure 3 The water outlet pipe 28 of this embodiment is bent multiple times, and each time the water outlet pipe 28 is bent, it is inclined toward the direction of the movable pile 5. The effect of this arrangement is to increase the acceleration of the water flowing from the driving chamber 7 through the water outlet pipe 28 and increase the water pressure.

[0036] See attached Figure 6 The bottom end of the water outlet pipe 28 is connected to each connecting hose 30, and the connecting hose 30 extends toward the bottom end of the annular cavity 12 until it passes through the bottom end of the annular cavity 12 and is connected to the corresponding nozzle 3 27. Figure 7The bottom of the annular pressing plate 13 is provided with a notch 31, the top surface of the notch 31 is a plane, the height of the notch 31 is greater than or equal to the diameter of the connecting hose 30, that is, the connecting hose 30 can pass through the notch 31, and the side walls on both sides of the notch 31 are arc surfaces protruding toward the inner side of the notch 31, and the side walls of the arc surface can make the annular pressing plate 13 at the notch 31 slowly flatten the connecting hose 30. The width of the notch 31 is preferably such that when one connecting hose 30 is just cut off by the bottom surface of the annular pressing plate 13, another connecting hose 30 adjacent to the connecting hose 30 just enters the notch 31. In order to prevent the connecting hose 30 from sliding, the part of the connecting hose 30 located in the annular cavity 12 can be pasted on the bottom surface of the annular cavity 12. The control panel 2 of this embodiment is used to set relevant parameters and control the water pump 1 32, the water pump 2 20, the solenoid valve 1 34, the solenoid valve 2 24, the solenoid valve 3 25, the solenoid valve 4 41 and the solenoid valve 5 42 to be opened or closed.

[0037] The use principle of this embodiment is as follows: when installing the device, the water inlet pipe 23 and the water inlet pipe 5 26 are connected to the external water source to supply water to the device, and the water inlet pipe 6 40 is connected to the floating chamber 3. When dust reduction is required, the water pump 1 32 and the electromagnetic valve 1 34 are turned on first, and the water pump 1 32 pumps water into the floating chamber 3. Due to the buoyancy of the water, the movable pile 5 gradually floats out of the floating chamber 3 until the limit block 38 reaches the top of the limit groove 37, or the top of the movable pile 5 rises to a specified height, and then the water pump 1 32 and the electromagnetic valve 1 34 are turned off;

[0038] When 360° spray dust suppression is required, the electromagnetic valve 24 and the electromagnetic valve 5 42 are opened, the electromagnetic valve 3 25 and the electromagnetic valve 4 41 are closed, and the water pump 20 is turned on. The water pump 20 pumps water into the annular channel 14 through the outlet pipe 1 21 and the inlet pipe 3 22. The water is sprayed from the nozzle 17 of the annular channel 14 through the perforation 16 and sprayed toward the impact plate 9. The impact plate 9 is affected by the impact force of the water, which will drive the turntable 8 to rotate, thereby driving the connecting plate 11 and the annular pressure plate 13 to rotate. The part of the bottom of the annular pressure plate 13 without the notch 31 will flatten the connecting plate 11. The position where the notch 31 is provided at the bottom of the annular pressing plate 13 will not flatten the corresponding connecting hose 30, so when a certain connecting hose 30 is in the notch 31, the water flowing into the bottom end of the outlet pipe 2 28 through the outlet pipe 1 21 and the outlet pipe 3 29 and the water flowing into the outlet pipe 2 28 from the driving chamber 7 will flow into the corresponding connecting hose 30, and then sprayed out from the nozzle 3 27 connected to the connecting hose 30. As the annular pressing plate 13 rotates, the nozzle 3 27 in the spray block 6 will spray water mist in sequence, thereby achieving the purpose of 360° water spraying;

[0039] When only one nozzle 3 27 is needed to spray water mist, water is still directed toward the impact plate 9 in the aforementioned manner to drive the turntable 8 to rotate. When the turntable 8 drives the notch 31 of the annular pressure plate 13 to rotate to the connection hose 30 connected to the corresponding nozzle 3 27, the solenoid valve 24 is closed, the turntable 8 stops rotating, and water mist is sprayed out from the corresponding nozzle 3 27.

[0040] When only a few nozzles 3 27 within a certain angle range need to be opened, the solenoid valve 3 25 and the solenoid valve 2 24 are opened and closed alternately. When the solenoid valve 2 24 is opened, the water flows toward the impact plate 9, driving the turntable 8 to rotate in the clockwise direction; when the solenoid valve 24 is closed, the solenoid valve 3 25 is opened, the water flows toward the impact plate 9, driving the turntable 8 to rotate in the counterclockwise direction, and then driving the annular pressure plate 13 to rotate alternately in the clockwise and counterclockwise directions, so that the connecting hoses 30 connected to the corresponding nozzles 3 27 appear alternately in the notch 31, and then the corresponding nozzles 3 27 spray water mist back and forth.

[0041] The above is an embodiment of the present invention. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly describing the invention verification process, and are not intended to limit the protection scope of the present invention.
