Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction, in particular to a road dust reduction device. Background Art

[0002] During material transportation operations at construction sites, cleaning vehicles frequently cross the interface between clean and contaminated areas. The existing traffic flow still has two major technical flaws when vehicles enter contaminated areas after primary cleaning in a car wash:

[0003] Secondary pollution residue: Mud carried in tire grooves and dirt left in the gaps between vehicles form a continuous dust source during driving;

[0004] Dust diffusion chain reaction: Scattered soil is compacted by subsequent vehicles to form inhalable particulate matter (PM10) with a particle size of ≤100μm, which produces continuous dust pollution under the action of wind.

[0005] Existing construction site dust suppression devices, such as CN119771095A, "A Road Dust Suppression Device for Green Building Construction," and CN119701529A, "A Road Dust Suppression Device for Highway Construction," have the following limitations: The dust suppression principle utilizes wide-area atomization, resulting in high water consumption and reduced visibility, impacting operational safety. They are unable to address tire-induced pollutants in real time, and fail to address dust reduction from the perspective of reducing road dust accumulation and, consequently, raising dust. Existing technologies lack a coordinated control system that blocks pollution sources, collects accumulated dust, and actively suppresses raised dust. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide a road dust reduction device to solve the problems that the existing dust reduction principle adopts wide-area atomization dust reduction, consumes a lot of water resources, reduces visibility and affects work safety, and cannot handle pollutants dynamically shed by tires. It does not consider the dust reduction problem from the perspective of reducing road dust accumulation to reduce dust.

[0007] The technical solution to achieve the above-mentioned purpose is: a road dust reduction device, comprising: a base, which is paved along the road and has a groove on the top of the base; a grille cover, which is arranged above the groove on the base, and a dust storage space is formed between the grille cover and the groove, which can collect attachments dropped from the tires when the vehicle is driving; a support assembly, which is supported between the groove and the grille cover; two ramps, which are respectively arranged at the two ends of the road near the base, and can allow the vehicle to drive to or leave the base through the corresponding ramps; a cleaning assembly, which is arranged in the base and the ramp, and is used to clean and discharge the attachments collected in the base.

[0008] The road dust suppression device of the present invention utilizes a tiered driving platform formed by a base and a grille cover. The upper layer of the grille cover allows vehicles to travel, while the lower layer, supported by a support assembly, provides a dust storage space that collects debris dropped from vehicle tires, effectively reducing dust on the road surface. Periodic flushing of the cleaning assembly clears and removes debris from the dust storage space, effectively preventing accumulation. This creates a three-in-one dust control system combining dynamic separation, directional diversion, and intelligent flushing.

[0009] A further improvement of the road dust reduction device of the present invention is that the bottom wall of the groove forms a V-shaped slope structure, and the V-shaped slope structure can receive the attached object.

[0010] A further improvement of the road dust reduction device of the present invention is that the support assembly includes: multiple groups of arched support bodies, multiple groups of arched support bodies are arranged in rows and at intervals on the slope surface of the V-shaped slope structure; multiple groups of support columns, multiple groups of support columns are arranged on the slope surface of the V-shaped slope structure, and are arranged in rows between adjacent groups of arched supports.

[0011] A further improvement of the road dust reduction device of the present invention is that the cleaning component includes: two groups of first water spray outlets, which are respectively arranged along the top of the slope on both sides of the V-shaped slope structure, and can flush the slope surface of the V-shaped slope structure; a first drainage trough, which is arranged along the bottom of the V-shaped slope structure, and can collect the water flow and attachments flushed on the V-shaped slope structure; a second water spray outlet, which is arranged at a side port of the first drainage trough, and the second water spray outlet can flush the first drainage trough.

[0012] A further improvement of the road dust reduction device of the present invention is that one side port of the first drainage trough is a water inlet, and the other side port is a water outlet.

[0013] A further improvement of the road dust reduction device of the present invention is that the cleaning component further includes: a second drainage trough, which is arranged in the ramp near the water outlet of the first drainage trough.

[0014] A further improvement of the road dust reduction device of the present invention is that a drainage ditch is provided on one side of the road; and an outer notch of the second drainage ditch is connected to the drainage ditch.

[0015] A further improvement of the road dust reduction device of the present invention is that the cleaning component also includes: a water inlet pipe, which is arranged in the ramp near the water inlet of the first drainage trough, and the water inlet pipe is connected to the second water spray port.

[0016] A further improvement of the road dust reduction device of the present invention is that the first water spray port is arranged between adjacent arched support bodies.

[0017] A further improvement of the road dust reduction device of the present invention is that a plurality of through holes are provided on the grille cover, and the through holes can allow the attachments to pass through. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] See Figure 1 and Figure 2 , Figure 1 A side view of a road dust suppression device according to the present invention is shown. Figure 2 The figure shows a transverse cross-sectional view of a road dust reduction device according to the present invention. The present invention provides a road dust reduction device, comprising: a base 1 , the base 1 is laid along a road 6 , and a groove 11 is provided on the top of the base 1 .

[0024] Among them, the base 1 can be made of steel with strong supporting force, which can support and maintain stability when the vehicle is driving. The width of the base 1 is set according to the size of the road 6, and the length of the base 1 and the size of the groove 11 are set according to actual needs, and no specific restrictions are made here.

[0025] The grille cover 2 is arranged above the groove 11 on the base 1, and a dust storage space is formed between the grille cover 2 and the groove 11, which can collect attachments that fall from the tires when the vehicle is driving.

[0026] Grille cover 2 is made of the same steel material as base 1, forming a high-strength support panel above base 1. The dimensions of grille cover 2 correspond to the dimensions of recess 11, and are not specifically limited herein. Adherent matter may be dust from vehicle tires or other fine particles, and are not specifically limited herein.

[0027] In other embodiments, the grille cover 2 may be made of aluminum or alloy materials, which is not specifically limited here.

[0028] The support assembly 3 is supported between the groove 11 and the grille cover 2 .

[0029] The supporting assembly 3 is described in detail below and will not be elaborated here.

[0030] Two ramps 4 are respectively arranged on the road 6 at both ends close to the base 1, and vehicles can drive onto the base 1 or leave the base 1 through the corresponding ramps 4.

[0031] The two ramps 4 are arranged in opposite directions, corresponding to the uphill and downhill directions of the vehicle respectively.

[0032] In this embodiment, the slopes of the two ramps 4 are set to be consistent. The slope of the ramp 4 is set according to actual construction requirements, and there is no specific restriction on the slope of the ramp 4.

[0033] The cleaning component 5 is arranged in the base 1 and the ramp 4. The cleaning component 5 is used to clean and discharge the attachments collected in the base 1.

[0034] The cleaning component 5 is described in detail below and will not be elaborated here.

[0035] See Figure 3 , showing a side cross-sectional view of a road dust suppression device of the present invention. The present invention provides a road dust suppression device, wherein the bottom wall of the groove 11 forms a V-shaped slope structure 12, and the V-shaped slope structure 12 can receive attached objects.

[0036] The attached objects pass through the grid cover and fall onto the slope of the V-shaped slope structure 12. When the vehicle is moving, the base 1 and the V-shaped slope structure 12 vibrate, allowing the attached objects to slide along the slope to the bottom and collect at the bottom. The length of the V-shaped slope structure 12 is consistent with the direction of vehicle travel.

[0037] In this embodiment, the slopes on both sides of the V-shaped slope structure 12 are opposite and symmetrically arranged. The slope and size of the V-shaped slope structure 12 are set according to the inner wall size of the base 1 and specific actual needs, and are not specifically limited here.

[0038] See Figure 2 and Figure 3 , Figure 2 A transverse cross-sectional view of a road dust suppression device according to the present invention is shown. Figure 3 The present invention provides a road dust reduction device, wherein the support assembly 3 comprises a plurality of arch support bodies 31 arranged in rows and spaced apart on the slope surface of the V-shaped slope structure 12 .

[0039] The arched supports 31 are vertically arranged on the slope of the V-shaped slope structure 12, and the arched supports 31 in each group are spaced apart. The size of the arched supports 31 is set according to the height difference between the slope of the V-shaped slope structure 12 and the grille cover 2, and is not specifically limited here.

[0040] In this embodiment, a plurality of arched support bodies 31 are arranged around the grille cover 2 along the slope of the V-shaped slope structure 12 at intervals, and the arched support bodies 31 on both sides of the slope of the V-shaped slope structure 12 are symmetrically arranged.

[0041] Multiple groups of support columns 32 are arranged on the slope surface of the V-shaped slope structure 12 and are arranged in rows between adjacent groups of arch supports.

[0042] The upper and lower rows of support columns 32 are staggered to provide multi-point support for the grille cover 2, thereby providing a stable supporting force and ensuring the stability of the vehicle.

[0043] In this embodiment, the support columns 32 on both sides of the V-shaped slope structure 12 are also vertically symmetrically arranged. The size of the support columns 32 is set according to the height difference between the slope of the V-shaped slope structure 12 and the grille cover 2, and is not specifically limited here.

[0044] See Figure 2 and Figure 3 , Figure 2 A transverse cross-sectional view of a road dust suppression device according to the present invention is shown. Figure 3 A side cross-sectional view of a road dust suppression device according to the present invention is shown. The present invention provides a road dust suppression device, wherein a cleaning assembly 5 includes two sets of first water spraying ports 51 , which are disposed opposite each other along the tops of two sides of a V-shaped slope structure 12 , respectively, for flushing the slope surface of the V-shaped slope structure 12 .

[0045] The two groups of first water spraying ports 51 are arranged in rows and at intervals along the tops of the slopes on both sides of the V-shaped slope structure 12 .

[0046] In this embodiment, the first water spray outlet 51 is a fan-shaped water spray outlet, and the spraying directions of the two groups of first water spray outlets 51 are arranged along the slope surfaces on both sides of the V-shaped slope structure 12, so that the sprayed water body flushes the slope surfaces on both sides of the V-shaped slope structure 12, and can allow the attachments on the slope surface to flow with the water body, and the water flow can carry the attachments toward the bottom of the slope, thereby achieving the cleaning of the slope surface.

[0047] In this embodiment, the first water jet 51 can be periodically flushed, with a 2-hour interval and a duration of 120 seconds. During the period when the first water jet 51 is closed, the residual water on the slope of the V-shaped slope structure 12 acts as a moisture-retaining layer, which can form a cohesive dust layer with any attached objects. This dust can then be moved down the slope by the vibrations of the vehicle during driving, rather than being emitted outside the device as dust. This eliminates the need for continuous spraying to suppress dust in the air, thus conserving water resources.

[0048] In other embodiments, the spraying interval and duration can be set according to specific needs, and are not specifically limited here.

[0049] The first drainage trough 52 is provided along the bottom of the V-shaped slope structure 12 , and can collect the flushing water and attachments on the V-shaped slope structure 12 .

[0051] The second water spray port 53 is provided at a side port of the first drainage trough 52 . The second water spray port 53 can flush the first drainage trough 52 .

[0052] Among them, the second water spray port 53 is a pulsed high-pressure nozzle with strong cleaning power.

[0053] In this embodiment, the second water jet port 53 is used to perform high-pressure flushing to prevent accumulation of attachments in the first drain groove 52 and blockage.

[0054] In this embodiment, the second water spray port 53 is provided to implement periodic flushing, with an interval of 3 minutes per time and a duration of 30 seconds.

[0055] In other embodiments, the interval time and duration of the spraying of the second water spray port 53 can be set according to specific needs, and are not specifically limited here.

[0063] The drainage ditch 61 is provided outside the two ramps 4 , and the drainage ditch 61 receives the water and attachments discharged from the second drainage groove 54 .

[0064] In this embodiment, the first drainage groove 52 and the drainage ditch 61 are provided to avoid water accumulation on the road surface that would affect pedestrians, while also preventing water from splashing when vehicles pass by.

[0065] See Figure 2 , showing a transverse cross-sectional view of a road dust suppression device according to the present invention. The present invention provides a road dust suppression device, wherein the cleaning assembly 5 further comprises: a water inlet pipe 55 , which is disposed within the ramp 4 at the water inlet near the first drain trough 52 , and is connected to the second water spray port 53 .

[0066] Among them, a channel is provided in the ramp 4 arranged near the water inlet of the first drainage trough 52, which facilitates the laying of the water inlet pipe 55 along the channel.
