Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and specifically to a dust reduction device for building construction. Background Art

[0002] Building construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. During building construction, there will be excessive dust on the construction site. In order to prevent the dust from escaping and affecting the surrounding workers, dust reduction equipment is usually set up on the construction site, and the water mist sprayed by the dust reduction equipment is used to inhibit the diffusion of dust.

[0003] Chinese invention patent with the publication number CN116550076A discloses a building construction dust reduction device and a dust reduction method, including a moving bottom plate. The middle of the upper end of the moving bottom plate is fixedly connected with a protective barrel, and a water tank is installed inside the protective barrel. A water injection pipe is installed at the upper end of the water tank; it also includes: a support frame fixedly installed in the middle of the upper end of the protective barrel. The left and right sides of the support frame are penetrated and installed with diversion pipes, and the upper ends of the diversion pipes are communicated with a spray plate. The lower ends of the diversion pipes are connected with a drainage swing structure through a water delivery pipe; a water suction pipe for connecting the drainage swing structure and the water tank, and one-way valves are installed on both the water suction pipe and the diversion pipe. This patent can improve the spraying range of the water mist during use, and at the same time, in summer or winter, it can cool or heat the sprayed water source to avoid the evaporation or condensation of the sprayed water mist and improve the overall dust reduction effect.

[0004] However, the above patent still has the following deficiencies in actual use: In cold weather, the patent uses the heat generated by the extrusion and friction of adjacent friction balls to heat the diversion pipe. However, the effect of heating the diversion pipe only by the heat generated by the friction balls is very small, and the water source in the heat conduction pipe itself has a relatively fast flow rate, and the heat exchange time when passing through the diversion pipe is also very short. This results in the fact that the sprayed water source is not heated at all, and the water source will still condense after spraying out for a short distance. Summary of the Invention

[0005] In order to make up for the above deficiencies, the present invention provides a dust reduction device for building construction to solve the problem of how to avoid the condensation of the water source after spraying out for a short distance in cold weather as mentioned in the above background art.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] First, the present invention introduces the water source inside the inner ring partition into the flow conversion box through the lifting and guiding mechanism. The first one-way valve can prevent the water source inside the inner ring partition from flowing back into the water tank.

[0019] Second, the present invention drives the linkage cylinder to rotate self - clockwise through the cooperation of the first motor and the first reduction gearbox. The concave ring groove on the linkage cylinder will guide the suspension rod to rise and fall. The suspension rod drives the synchronous rod and the extraction plate to rise and fall synchronously. When the extraction plate rises and falls, it can transfer a fixed amount of water source through the first one - way valve and the second one - way valve.

[0020] Third, the present invention can drive the chassis to rotate reciprocally clockwise and counter - clockwise through the driving mechanism, so that all the atomizing nozzles also rotate synchronously. The atomizing nozzles can generate centrifugal force, and the sprayed water source can be sprayed farther, so that the sprayed water source can act on a larger range for dust reduction.

[0021] Fourth, the present invention drives the screw rod to rotate through the cooperation of the second motor and the second reduction gearbox. The screw rod drives the lifting block to move up and down on it. The lifting block can drive one end of the linkage rod to rotate around the hinge point of the second hinge seat. The other end of the linkage rod can drive the first hinge seat and the hinge rod to rotate around the hinge point of the first hinge seat. In this way, the action area of all the atomizing nozzles can be changed, with strong flexibility and applicability. Description of the Drawings

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention

[0034] Please refer to Figure 1-9 , and the present invention will detail the above technical solutions through the following embodiments

[0035] A dust reduction device for building construction, comprising a moving vehicle body 1 and a power supply box body 2. A protective housing 3 is provided on the top of the moving vehicle body 1. A heating device 4 for continuously heating water source and a water tank 5 are provided in the protective housing 3. A water pipe 6 is provided between the heating device 4 and the water tank 5. The heating device 4 includes a flow-through box body 41, an inner ring partition 42, a water pump 43 and a lifting and guiding mechanism 44 for guiding the water source in the inner ring partition 42 into the flow-through box body 41. A heating mechanism 45 is provided in the lifting and guiding mechanism 44. The flow-through box body 41 is arranged on the top of the moving vehicle body 1. The inner ring partition 42 is arranged in the flow-through box body 41. One end of the water pipe 6 is communicated with the water tank 5, and the other end of the water pipe 6 sequentially penetrates through the flow-through box body 41 and the inner ring partition 42. A first one-way valve 61 is provided in the water pipe 6. The water pump 43 is located between the inner wall of the flow-through box body 41 and the outer wall of the inner ring partition 42. The lifting and guiding mechanism 44 is arranged in the inner ring partition 42. A sealing plate 31 is provided on the top of the protective housing 3. A water spraying device 7 is provided on the sealing plate 31. The water pump 43 is communicated with the water spraying device 7 through a hose. The power supply box body 2 is arranged beside the protective housing 3.

[0036] In the present invention, the water source in the inner ring partition 42 is guided into the flow-through box body 41 through the lifting and guiding mechanism 44. The first one-way valve 61 can prevent the water source in the inner ring partition 42 from flowing back into the water tank 5. The lifting and guiding mechanism 44 includes a pumping plate 441, a synchronous rod 442, a first reduction box 443, a first motor 444 and a linkage cylinder 445. A plurality of second one-way valves 4411 are provided on the pumping plate 441. A suspension rod 446 is provided at the top of the synchronous rod 442. An inner concave ring groove 4451 capable of guiding the suspension rod 446 to lift and lower as the linkage cylinder 445 rotates is provided on the inner wall of the linkage cylinder 445. The pumping plate 441 is hermetically and slidably arranged in the inner ring partition 42. The synchronous rod 442 is arranged on the top of the pumping plate 441. The head end of the suspension rod 446 is slidably arranged in the inner concave ring groove 4451. The first reduction box 443 is arranged on the top of the flow-through box body 41. The first motor 444 is arranged on the first reduction box 443. The linkage cylinder 445 is rotatably arranged in the flow-through box body 41. The top of the linkage cylinder 445 is connected to the output end of the first reduction box 443. The heating mechanism 45 is arranged on the top of the pumping plate 441.

[0037] The first motor 444 and the first reduction box 443 cooperate to drive the linkage cylinder 445 to rotate. The inner concave ring groove 4451 on the linkage cylinder 445 will guide the suspension rod 446 to lift and lower. The suspension rod 446 drives the synchronous rod 442 and the pumping plate 441 to lift and lower synchronously. When the pumping plate 441 rises, the pumping plate 441 pumps the water source in the water tank 5 into the inner ring partition 42 through the water pipe 6 and the first one-way valve 61. When the pumping plate 441 moves down, the water source in the inner ring partition 42 can flow to the upper end of the pumping plate 441 through all the second one-way valves 4411, so that the water source can be quantitatively transferred.

[0038] Further, the suspension rod member 446 includes a connecting plate 4461, a tail sleeve 4462, and a telescopic sleeve 4463. A spring 4464 is provided inside the tail sleeve 4462. The connecting plate 4461 is fixed to the top of the synchronizing rod 442. The tail sleeve 4462 is horizontally arranged on the side wall of the connecting plate 4461. The telescopic sleeve 4463 is slidably arranged on the tail sleeve 4462. One end of the spring 4464 abuts against the inner wall of the telescopic sleeve 4463. The elastic force of the spring 4464 can make the telescopic sleeve 4463 tightly abut against the inner concave annular groove 4451, thereby improving the stability of the lifting of the telescopic sleeve 4463, that is, improving the stability of the lifting of the extraction plate 441.

[0039] Furthermore, an arc surface 4465 is provided at the head end of the telescopic sleeve 4463, which can make the telescopic sleeve 4463 slide more smoothly in the inner concave annular groove 4451.

[0040] It should be noted that the heating mechanism 45 continuously heats the water source. The heating mechanism 45 includes a heating ring 451 and a heat conducting plate 452. An embedded groove is provided at the top of the extraction plate 441. The heating ring 451 is arranged in the embedded groove. The heat conducting plate 452 is arranged on the top of the extraction plate 441, and the heating ring 451 is connected to the heat conducting plate 452.

[0041] When the extraction plate 441 is at the lowest end of the inner ring partition plate 42, the heating ring 451 and the heat conducting plate 452 can heat the water source in the inner ring partition plate 42. Since the amount of water source in the inner ring partition plate 42 is limited and the heating ring 451 and the heat conducting plate 452 have sufficient heating efficiency, after the extraction plate 441 rises, the extraction plate 441 guides the heated water source between the flow - turning box body 41 and the inner ring partition plate 42. The water pump 43 can extract the heated water source to the spraying device 7 for spraying. The lifting of the extraction plate 441 can continuously transport the heated water source between the flow - turning box body 41 and the inner ring partition plate 42, which can ensure that the sprayed water source has a certain temperature, avoid condensation when the water source is sprayed at a short distance, extend the condensation time of the water source, that is, ensure that the water source can float in the air for a sufficient distance for dust reduction.

[0042] Of course, using a condensation ring to replace the heating ring 451 can also achieve cooling the water source in the inner ring partition plate 42. This can be applied in summer and can also extend the evaporation time.

[0043] A plurality of guiding blocks 4412 are provided on the side wall of the extraction plate 441. A plurality of guiding grooves 421 that are guidingly matched with the guiding blocks 4412 are provided on the inner wall of the inner ring partition plate 42. The cooperation between the guiding blocks 4412 and the guiding grooves 421 can prevent the extraction plate 441 from deflecting during lifting, ensuring the stability of the extraction plate 441 during lifting.

[0044] By cooperating the water spraying device 7 and the water pump 43, the water source located between the flow - turning box body 41 and the inner ring partition plate 42 can be pumped and sprayed. The water spraying device 7 includes a chassis 71, a second motor 72, a second speed reducer 73, a mounting plate 74, a screw rod 75 and a driving mechanism 76 for driving the chassis 71 to rotate reciprocally clockwise and counter - clockwise. A plurality of hinged rods 741 arranged at equal angles along its circumferential direction are hingedly mounted on the mounting plate 74. One end of the hinged rod 741 is provided with a flow - turning groove. One end of the flow - turning groove is provided with a water inlet 742, and the other end of the flow - turning groove is provided with a water outlet. An atomizing nozzle 743 is installed on the water outlet. A first hinge seat 744 is provided on the side wall of the hinged rod 741. A plurality of connecting columns 745 are provided at the bottom of the mounting plate 74. An avoidance hole is formed in the middle of the mounting plate 74. A lifting block 751 matched with the screw rod 75 is provided on the screw rod 75. A plurality of second hinge seats 752 arranged at equal angles along its circumferential direction are provided on the outer wall of the lifting block 751. A linkage rod 753 is hinged on the second hinge seat 752. The second motor 72 is vertically arranged on the top of the chassis 71. The second speed reducer 73 is arranged on the output end of the second motor 72. The screw rod 75 is vertically installed on the second speed reducer 73. The mounting plate 74 is fixedly connected to the top of the second speed reducer 73 through all the connecting columns 745. The screw rod 75 is located in the avoidance hole. The other ends of all the linkage rods 753 are respectively hinged to all the first hinge seats 744. The driving mechanism 76 is arranged on the top of the sealing plate 31. The chassis 71 is fixedly connected to the driving mechanism 76. The water inlet 742 is communicated with the water pump 43 through a hose.

[0045] By cooperating the second motor 72 and the second speed reducer 73 to drive the screw rod 75 to rotate, the screw rod 75 drives the lifting block 751 to move up and down on it. After the lifting block 751 moves down, it can drive one end of the linkage rod 753 to rotate around the hinge point of the second hinge seat 752, and the other end of the linkage rod 753 can drive the first hinge seat 744 and the hinged rod 741 to rotate around the hinge point of the first hinge seat 744. In this way, the action area of all the atomizing nozzles 743 can be changed, and the flexibility and applicability are relatively strong.

[0046] The chassis 71 can be driven by the driving mechanism 76 to rotate clockwise and counterclockwise reciprocally, so that all the atomizing nozzles 743 also rotate synchronously. The atomizing nozzles 743 can generate centrifugal force, and the sprayed water source can be sprayed farther, so that the sprayed water source can act on a larger range for dust reduction. The driving mechanism 76 includes a gear ring 761, an L-shaped bracket 762, a third motor 763, a half gear 764 and a sprocket 765. There are two L-shaped brackets 762, two half gears 764 and two sprockets 765. An inverted first rotating seat 766 is installed on one of the L-shaped brackets 762. A first rotating shaft 767 is provided on the first rotating seat 766. A second rotating shaft 711 is provided at the bottom of the chassis 71. A second rotating seat 311 is provided at the top of the sealing plate 31. The chassis 71 is rotatably arranged on the second rotating seat 311 through the second rotating shaft 711. The gear ring 761 is arranged on the chassis 71. The two L-shaped brackets 762 are symmetrically arranged on both sides of the second rotating seat 311. The third motor 763 is vertically arranged on the top of the other L-shaped bracket 762. A half gear 764 and a sprocket 765 are arranged on the output end of the third motor 763. The other half gear 764 and the other sprocket 765 are arranged on the second rotating shaft 711. The two sprockets 765 are connected by a chain drive. Both of the two half gears 764 are meshed with the gear ring 761.

[0047] The third motor 763 drives the half gear 764 and the sprocket 765 connected to the output end of the third motor 763 to rotate. The sprocket 765 drives the other sprocket 765 to rotate through the chain. The other sprocket 765 drives the first rotating shaft 767 to rotate. The first rotating shaft 767 drives the other half gear 764 to rotate. After one half gear 764 is meshed with the gear ring 761, the half gear 764 can drive the gear ring 761 to rotate clockwise. After the half gear 764 disengages from the gear ring 761, the other half gear 764 just meshes with the gear ring 761, and the other half gear 764 drives the gear ring 761 to rotate counterclockwise. In this way, the gear ring 761 can rotate reciprocally clockwise and counterclockwise, and the gear ring 761 drives the chassis 71 and all the atomizing nozzles 743 to rotate synchronously.

A plurality of water leakage holes 315 for communicating the collection hood 312 and the collection hopper 313 are also provided on the sealing plate 31. A filter screen is provided in the water leakage holes 315. Some of the water droplets sprayed by the atomizing nozzles 743 will fall on the top of the sealing plate 31. More water droplets can be collected through the collection hood 312. The water can be drained into the collection hopper 313 through the water leakage holes 315. The filter screen can filter the impurities in the water droplets. The water droplets enter the corrugated pipe 314 through the collection hopper 313, and then the water droplets can enter the water tank 5, so as to achieve the effect of saving water resources.

[0049] A plurality of vertically arranged lifting electric push rods 316 are provided inside the protection housing 3. The bottom of the sealing plate 31 is fixedly connected to the output ends of all the lifting electric push rods 316. The lifting electric push rods 316 can drive the sealing plate 31 to lift and lower, and the sealing plate 31 can drive all the atomizing nozzles 743 to lift and lower synchronously, thereby further increasing the action range of the atomizing nozzles 743.
