DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Existing dust suppression devices for construction projects use track-based installations to achieve mobile large-area spray dust suppression. This arrangement increases the burden on the traction mechanism, especially for traction of long power supply and water supply lines, which is difficult to achieve once the track is too long. In addition, the overall arrangement is too complicated, and it is not convenient to lay and disassemble and maintain later.

[0040] Embodiment 1

[0041] See attached Figure 1-9 As shown, in order to solve the above technical problems, a dust suppression device for construction engineering is provided, including: a support assembly 100, a track-type water supply assembly 200, a track-type power supply assembly 300, and a spray assembly 400.

[0042] In this solution, there are several support assemblies 100, and the several support assemblies 100 constitute a longer moving channel. Since the spray assembly 400 can move along the moving channel, the longer the moving channel is, the larger the area where the spray assembly 400 can reduce dust is.

[0043] The track-type water supply assembly 200 is arranged following the support assembly 100, and when the spray assembly 400 moves along the channel, there is no need to drag the water supply pipeline, but to absorb liquid during its movement. The track-type water supply assembly 200 does not need to move following the movement of the spray assembly 400. For the spray assembly 400, not only is its load greatly reduced, but water supply is no longer a problem no matter how long the channel is.

[0044] Similarly, the rail-type power supply assembly 300 also adopts a wireless power supply method to maintain power supply during the movement of the spray assembly 400, avoiding the use of a drag chain type wiring harness and a spring type wiring harness, which require the spray assembly 400 to drag and pull itself, thereby avoiding the problem of the traction mechanism being affected and causing limited movement.

[0045] Embodiment 2

[0046] Further improvements are made on the basis of the first embodiment, and a specific implementation of the support assembly 100 is provided.

[0047] See attached Figure 1 , 3 As shown in FIG. 4 , the support assembly 100 includes: a fixed bracket 110 , a U-shaped groove 120 , a C-shaped track member 130 , and a mounting plate 140 .

[0048] Among them, one side of the U-shaped groove 120 is connected to the outer wall of the C-shaped track member 130 through a reinforcing rib structure, the top of the fixed bracket 110 has a U-shaped groove 150 that cooperates with the outer wall of the U-shaped groove 120, and the U-shaped groove 120 is adapted to at least one fixed bracket 110, and the upper part of the fixed bracket 110 corresponds to one side of the C-shaped track member 130 and has a mounting plate 140.

[0049] Specifically, the U-shaped groove 120 is fixed to the outer wall of the C-shaped track member 130 by welding or clamping, so that the connection strength between the U-shaped groove 120 and the C-shaped track member 130 is sufficient, and the additional support structure for the C-shaped track member 130 is reduced, thereby achieving structural simplification.

[0050] The C-shaped structure can simplify the track required for the movement of the spray assembly 400, making the construction and disassembly of the track easier and more convenient.

[0051] In order to facilitate the cooperation between the fixed support frame 110 and the U-shaped groove 120, a U-shaped groove 150 is provided at the top of the fixed support frame 110. When the fixed support frame 110 is connected with the U-shaped groove 120, it is only necessary to insert the U-shaped groove 120 into the U-shaped groove 150.

[0052] Preferably, the fixed support frame 110 adopts an I-beam structure to ensure the structural support strength while simplifying the structure of the fixed support frame 110, and the connecting plate welded at the bottom is fixed by bolts. Preferably, the U-shaped groove 120 and the C-shaped track member 130 are both stamped parts. The mounting plate 140 is mainly used for the installation of the track-type power supply assembly 300 to provide it with sufficient support.

[0053] Preferably, in order to facilitate the connection of the U-shaped groove 120, connecting flanges 160 are provided at both ends of the U-shaped groove 120. When adjacent U-shaped grooves 120 are connected, the adjacent U-shaped grooves 120 can be fixed by bolting the butted connecting flanges 160.

[0054] The connected U-shaped groove 120 forms a longer U-shaped placement groove, and the track-type water supply component 200 can be laid in the U-shaped placement groove to construct a stable water supply pipeline.

[0055] Embodiment 3

[0056] Further improvements are made on the basis of the first embodiment, and a specific implementation of the track type water supply assembly 200 is provided.

[0057] See attached Figure 5 , 6 As shown, the track-type water supply assembly 200 at least includes: a water supply hose 210 , a self-sealing tape 220 , a pull head 230 , and a protective sleeve 240 .

[0058] Among them, the cross-section of the water supply hose 210 is U-shaped, one side of the self-sealing tape 220 is located at the opening edge of the water supply hose 210, and the other side of the self-sealing tape 220 cooperates with two pull heads 230, and the closing or opening of the corresponding side of the self-sealing tape 220 is realized during the movement of the pull head 230. The protective tube sleeve 240 is located between the two pull heads 230 and forms a whole with the pull head 230.

[0059] Specifically, the water supply hose 210 is used to facilitate its laying. Even if the U-shaped placement groove formed by the U-shaped groove 120 is irregular, it does not affect the laying of the water supply hose 210, and the adaptability is stronger. The U-shaped cross section is based on the working principle of the track water supply assembly 200.

[0060] When the track-type water supply assembly 200 is working, at least one end is connected to the water supply pipeline, and the water supply pipe continuously supplies water to the water supply hose 210, and the water in the water supply hose 210 is sucked by the spray assembly 400. Due to the continuous injection of water flow, the water inside the water supply hose 210 is relatively flowing. In order to ensure that the spray assembly 400 can fully absorb, the cross section of the water supply hose 210 is set to be U-shaped, that is, a flow channel with a certain depth. Even if the spray assembly 400 absorbs faster, the water can be kept at the absorption position for a longer time without affecting the operation of the spray assembly 400.

[0061] In addition, when in use, the water supply hose 210 is in an open state only at the protective sleeve 240, and the opening position moves on the water supply hose 210 following the movement of the spray assembly 400, ensuring that other positions of the water supply hose 210 always remain closed and are not polluted by external dust.

[0062] The pull head 230 can open or close the edge of the self-sealing belt 220 to form a structure similar to a self-sealing keel.

[0063] Preferably, the end of the water supply hose 210 is a closed structure and has a connection port 250 that is connected to an external waterway. That is, when the water supply hose 210 is connected to the water supply pipeline, it is achieved through the connection port 250. In addition, the water supply hose 210 has a connection port 250 on both ends of the closed structure. When in use, it is arranged as needed that one connection port 250 is connected to the water supply pipeline and the other connection port 250 is connected to the water outlet pipeline; both connection ports 250 are connected to the water supply pipeline; one connection port 250 is connected to the water supply pipeline and the other connection port 250 is closed. The selection method is mainly based on the suction speed of the spray assembly 400.

[0064] Embodiment 4

[0065] Further improvements are made on the basis of the first embodiment, and a specific implementation of the track-type power supply assembly 300 is provided.

[0066] See attached Figure 1 , 4 As shown in FIGS. 8 and 9 , the track-type power supply assembly 300 includes: a wireless power transmission track 310 and a water guide 320 .

[0067] The wireless power transmission track 310 is fixed to the fixed bracket 110 one by one through the mounting plate 140, the contact surface of the wireless power transmission track 310 is located on the bottom surface, and the water guide 320 is located on both sides of the bottom surface of the wireless power transmission track 310, so that the bottom surface of the wireless power transmission track 310 forms a W shape.

[0068] Specifically, the wireless power transmission track 310 draws on the existing wireless charging technology and is set as a long strip track structure. In order to avoid interference from rain, the contact surface of the wireless power transmission track 310 is set on the bottom surface, and water guide edges 320 are set on both sides of the bottom surface. The setting of the water guide edge 320 reduces the effect of rain on the contact surface of the wireless power transmission track 310, ensuring that it can provide stable power supply.

[0069] Embodiment 5

[0070] Further improvements are made on the basis of the first embodiment, and a specific implementation of the support assembly 100 is provided.

[0071] See attached Figure 1 , 7 As shown, the spray assembly 400 includes: a box assembly 410, a multi-angle spray head 420, a water intake pipe 430, a driving wheel 440, and a driven wheel 450.

[0072] Among them, the driven wheel 450 is distributed above one side of the box assembly 410, and the driving wheel 440 is distributed below the same side of the box assembly 410, and the driven wheel 450 rolls with the inner top wall of the C-shaped track member 130, and the driving wheel 440 rolls with the inner bottom wall of the C-shaped track member 130. One end of the water intake pipe 430 passes through the protective sleeve 240 and extends to the inside of the water supply hose 210, and the other end of the water intake pipe 430 is connected to the multi-angle nozzle 420 arranged in the box assembly 410 through the box assembly 410.

[0073] The driving wheel 440 is driven by a motor, and preferably, the motor is disposed inside the box assembly 410. When the driving wheel 440 rolls along the channel formed by the C-shaped track member 130 under the drive of the motor, the driven wheel 450 also rolls along the channel formed by the C-shaped track member 130. The main function of the driven wheel 450 is to cooperate with the movement of the driving wheel 440 to ensure that it moves stably on the C-shaped track member 130.

[0074] In this embodiment, the multi-angle nozzle 420 is arranged at the top of the box assembly 410, and the water intake end of the water intake pipe 430 is passed through the top of the box assembly 410 and then extended into the water supply hose 210 from the protective tube sleeve 240 to take water. The water intake pipe 430 is provided with a water pump for pressurizing water and then spraying it out from the multi-angle nozzle 420.

[0075] The multi-angle nozzle 420 is an existing structure, and this solution does not make much improvement to the existing structure, so it will not be described in detail.

[0076] Embodiment 6

[0077] Further improvements are made on the basis of the fifth embodiment, and a specific implementation of the conductive component 460 is provided.

[0078] See attached Figure 4 , 8 As shown in FIG. 9 , the conductive component 460 includes: a hollow guide rod 461 , a conductive slip ring 462 , and a conductive contact 463 .

[0079] Among them, the hollow structure inside the guide rod 461 is used to arrange the line. One end of the guide rod 461 is fixed to the box assembly 410, and a conductive slip ring 462 is installed on the other end of the guide rod 461. The conductive contact 463 is a cylindrical structure and is sleeved on the conductive slip ring 462. The conductive contact 463 always maintains contact with the transmission area of ​​the wireless power transmission track 310, and the wire inside the guide rod 461 is electrically connected to the conductive contact 463 through the conductive slip ring 462.

[0080] Specifically, the hollow structure inside the guide rod 461 is arranged with a circuit for supplying power to the components inside the box assembly 410. During operation, the conductive contact 463 is always in contact with the transmission area of ​​the wireless power transmission track 310. When the box assembly 410 moves along the track formed by the C-shaped track member 130, the conductive contact 463 rolls in the transmission area of ​​the wireless power transmission track 310, and the conductive slip ring 462 maintains a stable connection between the wire and the conductive contact 463 during the rolling process of the conductive contact 463.

[0081] Embodiment 7

[0082] According to another aspect of the present invention, there is also provided a dust reduction method of a dust reduction device, comprising the following steps:

[0083] S10, assembling the dust suppression device.

[0084] Specifically, before assembly, the area where dust needs to be suppressed is measured, and the fixing points of the fixed support frame 110 and the placement of the U-shaped groove 120 are planned. Then, the fixed support frame 110 is fixed, and then the U-shaped groove 120, the track water supply assembly 200, the track power supply assembly 300, and the spray assembly 400 are assembled one by one.

[0085] During actual assembly, one group of dust suppression devices and multiple groups of dust suppression devices are arranged according to the width of the area.

[0086] S20 , connecting the connection port 250 to an external waterway, and connecting the wireless power transmission track 310 to a power supply network.

[0087] After the assembly is completed, the track type water supply assembly 200 is connected to the external water supply pipeline through the connection port 250 to ensure water supply. The wireless power transmission track 310 is connected to the power supply network to realize power supply. Before starting work, it is also necessary to test the machine to ensure that the assembly and connection are fault-free.

[0088] S30, the box assembly 410 moves based on the control signal received by the transceiver 470, and the driving wheel 440 rolls along the channel formed by the C-shaped track member 130 to drive the box assembly 410 to move. At the same time, the water intake pipe 430 moves with the box assembly 410, draws water from the water supply hose 210, and sprays it out through the multi-angle nozzle 420.

[0089] The box assembly 410 moves back and forth or cyclically on the track formed by the C-shaped track member 130 according to a preset program, and the transceiver 470 is used to realize information exchange.

[0090] S40, completing dust reduction in the predetermined area.

[0091] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
