Description

Technical Field

[0001] The present invention relates to the technical field of earthwork engineering construction, and in particular to a dust reduction device and method for earthwork engineering construction. Background Art

[0002] During earthwork construction, water is sprayed on the construction site and surrounding areas through a sprinkler truck or a spray system, so that dust particles in the air absorb moisture, increase weight and settle. The frequency and amount of watering can be adjusted according to the actual situation of the construction site. Generally, the number of watering should be increased in dry and windy weather. During the excavation and transportation of earth, a sprinkler truck can be arranged to follow the operation and continuously sprinkle water on the excavation surface and transportation roads.

[0003] However, during the construction of earthwork projects, the sprinkler trucks used for spraying cannot extract wastewater for filtering, which easily causes waste of resources and reduces the efficiency of water resource utilization. At the same time, too much dust affects the normal operation and measurement accuracy of construction equipment, and the smooth progress of construction cannot be guaranteed. At the same time, the filter plate is easily blocked due to excessive dust on the surface. When the filter element fails, it cannot be replaced in time, the wastewater cannot be effectively purified, and the workload of the staff is increased. Summary of the invention

[0034] Reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a dust reduction method for earthwork engineering construction. Through the dust reduction device and method for earthwork engineering construction, wastewater utilization, switching water gun flushing and filter cleaning effects are achieved.

[0035] The dust suppression device is started during the construction of earthwork engineering, and the first filter plate 502 is used to filter groundwater or wastewater, thereby avoiding waste of water resources and improving the utilization efficiency of water resources. The water inlet is controlled by the switching component 505 to pump water from other water resources. The water delivery direction is changed through the S-shaped water tank 202c. The rotating assembly 202 operates the S-shaped water tank 202c to switch the water to the channel leading to the water gun mechanism 600. The water gun mechanism 600 flushes the loading machinery or measuring instruments during the construction process to prevent excessive dust from affecting the construction. When the switching component 505 is working, it also drives the cleaning component 505h to move. The movement of the first plug plate 505c and the second plug plate 505d can also drive the cleaning brush plate 505h-1 to move to clean the mud and dust on the surface of the first filter plate 502 and the second filter plate 503 to avoid clogging of the filter plates due to excessive impurities. At the same time, the filter element plate 504 is disassembled and fixed to facilitate the replacement of the filter element plate 504 to avoid the inability of the failed filter element to purify the wastewater to a certain extent.

[0036] Reference Figures 4 to 6 , which is the second embodiment of the present invention, provides an extrusion mechanism, through which the effect of adjusting the spraying range of the spray by using water pressure is achieved.

[0037] The spray mechanism 200 includes a protective cylinder 201, the bottom of the protective cylinder 201 is fixedly connected to the top of the working cylinder 103, the right side of the inner wall of the protective cylinder 201 is fixedly connected to a rotating component 202, the top of the rotating component 202 is fixedly connected to a hollow rod 203, the inner cavity of the hollow rod 203 is provided with a hose 204, the surface of the hollow rod 203 is movably connected to a movable rod 205, the left and right sides of the movable rod 205 are provided with water ports 206, four water ports 206 are provided and are equidistantly distributed, the right side of the water port 206 is fixedly connected to a water plate 207, the front end and back end of the right side of the water plate 207 are fixedly connected to a spray dust suppression device 208.

[0038] The extrusion mechanism 300 includes a first fixed plate 301, the left side of the first fixed plate 301 is fixedly connected to the bottom of the right side of the movable rod 205, the right side of the right side of the first fixed plate 301 is fixedly connected to the second fixed plate 302, the bottom of the left side of the second fixed plate 302 is movably connected to the first rotating gear 303 through a rotating shaft, the left side of the first rotating gear 303 is fixedly connected to the threaded rod 304, the surface of the threaded rod 304 is movably sleeved with a threaded sleeve 305, the left side of the threaded sleeve 305 is fixedly connected to a pressure block 306, the top and bottom of the inner cavity of the threaded sleeve 305 are both provided with a limiting rod 307, the right side of the limiting rod 307 passes through the right side of the threaded sleeve 305 and is fixedly connected to the left side of the second fixed plate 302, the inner cavity of the first fixed plate 301 is movably connected to the electric mechanism 400, the front end of the three-port pipe 104 is fixedly connected to the filter plate mechanism 500, and the top of the rotating component 202 is fixedly connected to the water gun mechanism 600.

[0039] The electric mechanism 400 includes a rotating block 401, which is arranged in the inner cavity of the first fixed plate 301. The front end and the back end of the rotating block 401 both penetrate the front end and the back end of the first fixed plate 301. The back end of the rotating block 401 is fixedly connected with the second rotating gear 402. The right side of the second rotating gear 402 is meshed with the front end of the first rotating gear 303. The front end of the rotating block 401 is fixedly connected with the first transmission gear 403. The front end of the first transmission gear 403 is fixedly connected with the first connecting block 404. The front end of the first connecting block 404 is fixedly connected with a rotating rod assembly 405. The rotating rod assembly 405 is fixedly connected with a second connecting block 406 at a position away from the first connecting block 404. The back end of the second connecting block 406 is fixedly connected with a transmission motor 407. The transmission motor 407 is fixed on the inner wall of the protective tube 201.

[0040] Specifically, multiple water openings 206 are distributed at equal distances, so that the spray dust reduction device 208 can perform dust removal work over a large area and improve the dust reduction effect. At the same time, the hose 204 can adapt to a certain degree of bending and deformation, and will not easily break or get blocked during the movement of the hollow rod 203 and the movable rod 205.

[0041] Specifically, the pressure block 306 can move to the left by the rotation of the threaded rod 304 to squeeze the hose 204 to increase the internal water pressure. At the same time, the limit rod 307 is fixed to the threaded sleeve 305 to ensure the directional accuracy and stability of the threaded sleeve 305 during movement.

[0042] Specifically, the threaded rod 304 can be rotationally controlled by the transmission motor 407. When the electric mechanism is working, the position of the pressure block in the extrusion mechanism can be accurately controlled to adjust the water pressure. At the same time, the transmission motor 407 can control the extrusion mechanism 300 and the rotating component 202 at the same time.

[0043] Furthermore, the bottom of the protective cylinder 201 is fixedly connected to the top of the working cylinder 103, providing support and fixation for the entire spray mechanism. The liquid can enter the movable rod 205 through the hose 204 and the hollow rod 203, and flow to the water plate 207 through four equidistantly distributed water openings 206. The front end and the back end of the right side of the water plate 207 are fixedly connected to the spray dust reduction device 208, which is converted into a spray spray under the action of the spray dust reduction device 208 to achieve dust reduction and other functions.

[0044] Furthermore, when the first rotating gear 303 rotates, the threaded rod 304 fixedly connected to the left side of the first rotating gear 303 rotates accordingly. When the threaded rod 304 rotates, the threaded sleeve 305 movably sleeved on the surface is restricted by the limiting rod 307 and moves to the left along the axis of the threaded rod 304. The pressure block 306 also moves accordingly to squeeze and pressurize the hose 204.

[0045] Furthermore, the transmission motor 407 drives the second connecting block 406 to rotate through the rotating rod assembly 405, and the rotation of the first connecting block 404 drives the first transmission gear 403, the rotating block 401 and the second rotating gear 402 to follow the rotation, and the first rotating gear 303 follows the rotation and drives the threaded rod 304 to rotate at the same time, so as to accurately control the extrusion mechanism 300.

[0046] Reference Figure 2 and 3 , which is the third embodiment of the present invention, provides a cleaning piece, through which the filter screen can be cleaned.

[0047] The switching assembly 505 includes a mechanical gear 505a, a small slow motor 505b is fixedly connected to the right side of the mechanical gear 505a, and the small slow motor 505b is arranged in the inner cavity of the control board 501. The top and bottom of the inner cavity of the control board 501 and the left sides corresponding to the first filter plate 502 and the second filter plate 503 are movably connected with the first plug plate 505c and the second plug plate 505d, the bottom of the first plug plate 505c and the top of the second plug plate 505d are both provided with a first rack 505e and a second rack 505f, the top and bottom of the mechanical gear 505a are meshed with the bottom of the first rack 505e and the top of the second rack 505f, the inner cavities of the first plug plate 505c and the second plug plate 505d and the positions corresponding to the first filter plate 502 and the second filter plate 503 are provided with control ports 505g, and a cleaning piece 505h is provided on the right side of the first plug plate 505c.

[0048] The cleaning part 505h includes a cleaning brush plate 505h-1, the left side of the cleaning brush plate 505h-1 is fixedly connected to the right side of the first plug plate 505c, the top of the first plug plate 505c is fixedly connected with an arc-shaped baffle plate 505h-2, and the bottom of the arc-shaped baffle plate 505h-2 is in contact with the top of the control board 501 and the filter element board 504.

[0049] Specifically, the small slow motor 505b drives the mechanical gear 505a to rotate. Since the top and bottom of the mechanical gear 505a are meshed with the bottom of the first rack 505e and the top of the second rack 505f, when the mechanical gear 505a rotates, it will drive the first plug plate 505c and the second plug plate 505d to move in opposite directions.

[0050] Specifically, the left side of the cleaning brush plate 505h-1 is fixedly connected to the right side of the first plug plate 505c. When the first plug plate 505c moves, the cleaning brush plate 505h-1 moves accordingly. During the movement, the cleaning brush plate 505h-1 can directly contact the surface of the filter plate and remove impurities and dirt on the filter plate by brushing.

[0051] Furthermore, the small slow-speed motor 505b is started to drive the mechanical gear 505a to rotate. The rotation of the mechanical gear 505a will drive the first plug plate 505c and the second plug plate 505d to move toward each other through the first rack 505e and the second rack 505f, closing the top water inlet pipe 506 while opening the water inlet of the bottom water inlet pipe 506 to pump water from other water resources.

[0052] Furthermore, the movement of the first plug plate 505c and the second plug plate 505d can also drive the cleaning brush plate 505h-1 to move to clean the mud and dust on the surface of the first filter plate 502 and the second filter plate 503, avoiding clogging of the filter plates due to excessive impurities, while improving automation efficiency and reducing manual operations.

[0053] The remaining structure is the same as that of Example 2.

[0054] Reference Figures 1 to 9 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a dust suppression device for earthwork engineering construction.

[0055] During the construction of earthwork engineering, the dust suppression device is started, and groundwater or sewage is extracted through the top water inlet pipe 506. Then the water source is filtered through the first filter plate 502 to filter out some impurities and larger waste materials, and then purified through the filter element plate 504 to avoid waste of water resources and improve the utilization efficiency of water resources. If there is no need to extract groundwater or sewage, the small slow motor 505b is started to drive the mechanical gear 505a to rotate. The rotation of the mechanical gear 505a will drive the first plug plate 505c and the second plug plate 505d to move toward each other through the first rack 505e and the second rack 505f, close the top water inlet pipe 506 and open the water inlet of the bottom water inlet pipe 506 to pump other water resources. The movement of the first plug plate 505c and the second plug plate 505d can also drive the cleaning brush plate 505h-1 to move to clean the mud and dust on the surface of the first filter plate 502 and the second filter plate 503 to avoid clogging of the filter plates due to excessive impurities.

[0056] The water is sent to the inside of the water block 202b through the water pump 105, and then the water is transmitted to the hose 204 through the S-shaped water tank 202c. The water pressure will slowly push the movable rod 205 upward until the water outlet 206 at the bottom leaks out. Then the spray dust reduction device 208 starts to spray and reduce dust, and at the same time, it will drive the first fixed plate 301, the second fixed plate 302, the first rotating gear 303, the threaded rod 304, the threaded sleeve 305, the pressure block 306 and the limit rod 307 to follow the movement through the rotating rod assembly 405. If a larger spraying range is required, the transmission motor 407 is started to spray through the second small The gear 405h drives the first small gear 405f, the hollow long rod 405d and the cross limiting long rod 405e to rotate, and the first connecting block 404 rotates accordingly, driving the first transmission gear 403, the rotating block 401, the second rotating gear 402, the first rotating gear 303 and the threaded rod 304 to rotate, and at the same time, the threaded sleeve 305 and the pressure block 306 move to the left through the limiting rod 307 to squeeze the hose 204. After the hose 204 becomes thinner, the pressure in the tube increases to make the movable rod 205 continue to move upward. According to the needs, the spray dust reduction device 208 can be completely exposed to the outside to carry out a large range of dust reduction work.

[0057] When the spraying is turned off, the movable rod 205 slowly moves downward to the initial state. At this time, the first transmission gear 403 and the second transmission gear 202f are in a meshing state. The transmission motor 407 can simultaneously control the rotation of the second transmission gear 202f, so that the second control gear 202g drives the first control gear 202d and the water block 202b to rotate through the hollow box 202a, thereby changing the water flow direction of the S-shaped water tank 202c and aligning the water hole of the S-shaped water tank 202c with the water gun tube 601. The water flow can enter the rubber tube 602 through the water gun tube 601 and be sprayed out from the water gun head 603 to flush the loading machinery or measuring instruments during the construction process to avoid excessive dust affecting the construction.

[0058] In summary, the filter plate mechanism 500 can be used to filter groundwater or wastewater, thereby improving the utilization efficiency of water resources. The water inlet is controlled by the switching component 505 to facilitate the switching of water resources. The spray mechanism 200 is used to reduce dust at the construction site. The water gun mechanism 600 is used to flush the loading machinery or measuring instruments during the construction process to prevent excessive dust from affecting the construction.
