Description

Technical Field

[0001] This invention belongs to the field of road surface pollutant treatment technology, and particularly relates to a high-efficiency collection device and method for highway road surface pollutants. Background Technology

[0002] Highway road surface pollutants are diverse, mainly including mud, oil stains, total suspended particulate matter (TSP), and vehicle exhaust emissions. These pollutants come from a wide range of sources and can have adverse effects on road structure and the environment.

[0003] Currently, existing technologies for collecting pollutants from highway pavements have the following drawbacks: (1) Low cleaning and collection efficiency: Traditional devices mostly use a single mechanical cleaning or negative pressure adsorption method, which makes it difficult to simultaneously and efficiently clean large particles of garbage and fine dust. Dust is easily generated during the cleaning process, and garbage is easily left behind or scattered, leading to secondary pollution.

[0004] (2) Complex equipment maintenance and repair: The existing equipment's garbage collection containers are mostly fixed, making disassembly and cleaning difficult. The collection cylinder and key filter components are inconvenient to disassemble and assemble, lacking a quick connection and separation mechanism. The steps for cleaning or replacing the filter element are cumbersome, increasing maintenance time and labor costs, affecting the equipment's continuous operation capability and operational convenience.

[0005] In summary, existing technologies for efficient collection devices of pollutants on highway pavements suffer from low cleaning and collection efficiency as well as complex equipment maintenance and repair. Summary of the Invention

[0006] This invention provides a high-efficiency collection device and method for highway pavement pollutants, which can solve the problems of low cleaning and collection efficiency and complex equipment maintenance and repair in existing high-efficiency collection devices for highway pavement pollutants.

The power suction pump provides negative pressure to the collection cylinder through the power connection pipe so as to suck up the cleaned garbage through the garbage suction pipe and the adsorption hood. And a connection and separation component, located in the equipment installation area, for assembling and disassembling the collection cylinder.

[0008] A further improvement is that the roller brush assembly includes a frame fixedly connected to the front end of the cleaning chamber, a pair of oblique sweeping brushes rotatably mounted on the frame, and a pair of synchronous motors fixedly connected to the frame, the output main shaft of which is respectively connected to each of the oblique sweeping brushes; and a straight brush roller rotatably mounted inside the cleaning chamber.

[0009] A further improvement is that the self-propelled assembly includes rotatable wheels on both sides of the outside of the cleaning chamber, a synchronous gear fixedly sleeved on the shaft of the rotatable wheels, a power gear rotatably disposed on one side of the outside of the cleaning chamber and connected to the straight brush roller, and a DC servo motor fixedly connected to the outside of the cleaning chamber and connected to the output main shaft and the straight brush roller. The power gear and the synchronous gear are meshed together.

[0010] A further improvement is that a fixing seat is fixedly connected to the bottom inner wall of the equipment installation area, and the fixing seat is provided with a slot for accommodating the bottom of the collection cylinder; The connection and separation assembly includes a main magnet fixedly embedded in the slot, a magnetic suction plate fixedly connected to the bottom of the collection tube for adsorption and engagement with the main magnet, and a rubber retainer ring sleeved on the lower part of the outside of the collection tube. The outer diameter of the rubber retainer ring is larger than the width of the slot so as to engage with the side wall of the slot when the collection tube is inserted.

[0011] A further improvement is that the connection separation assembly also includes a limiting structure for laterally limiting the collection cylinder; The limiting structure includes two limiting frames and a locking screw. The two limiting frames are slidably disposed on both sides of the surface of the fixed base. Each limiting frame is L-shaped, and its vertical rod is used to abut against the side wall of the collecting cylinder. Each limiting frame has an elongated adjustment groove along its length on its horizontal rod. The locking screw passes through the adjustment groove and is threadedly connected to the fixed base to lock the limiting frame onto the fixed base.

[0012] A further improvement is that the collection cylinder is provided with a waste barrier chamber, and a filter element structure is provided in the waste barrier chamber. The filter element structure includes a mounting rod, an air filter element fixedly connected in the mounting rod, and a rubber ring sleeved on the outside of the mounting rod. Several arrays of fixing bolts are provided on the outside of the collection cylinder at the positions corresponding to the filter element structure. The collection cylinder is fixedly connected by the fixing bolts, the rubber ring, and the mounting rod.

[0013] A further improvement is that the surface of the cleaning chamber is provided with an inspection cover, several hooks are fixedly connected in the item placement area, and the collection cylinder is located in the equipment installation area.

[0014] A method for using a high-efficiency collection device for highway pavement pollutants, characterized by comprising the following steps: Step 1: On-site personnel transport the device to the section of the highway to be cleaned. By activating the self-propelled assembly, the wheels begin to rotate. The power gear transmits power through meshing with the synchronous gear, driving the wheels to propel the entire device forward at a constant speed along the road surface. Simultaneously, the DC servo motor and synchronous motor of the drive roller brush assembly start, causing the straight brush roller and a pair of oblique sweeping brushes to rotate synchronously, ready for cleaning operations; Step 2: During the movement of the device, the roller brush assembly works close to the road surface. The angled sweeping brushes are arranged at an angle to sweep the garbage inward from the shoulder and edge areas; the straight brush rollers are responsible for pushing the garbage in the central area of ​​the road surface backward, allowing various pollutants to gather in the area directly in front of the adsorption hood behind the sweeping chamber; Step 3: Start the power suction pump to establish a stable negative pressure inside the collection cylinder through the power connection pipe. The garbage suction pipe connects the adsorption hood to the collection cylinder. Under the action of negative pressure, the garbage collected by the roller brush assembly is sucked into the adsorption hood and transported through the garbage suction pipe to the garbage barrier chamber inside the collection cylinder, where it falls onto the filter structure. Step 4: When the waste in the collection cylinder reaches its maximum capacity or needs to be emptied, first turn off the power suction pump and stop the device from operating. Open the inspection cover and enter the equipment installation area. Loosen the locking screws on the two limit brackets, allowing the limit brackets to slide along the adjustment grooves. After releasing the lateral limit on the collection cylinder, disconnect the power to the main magnet. Pull the collection cylinder upwards; the magnetic suction plate and the main magnet will attract each other, and the rubber retainer will disengage from the side wall of the slot, allowing the entire collection cylinder to be removed. Then, open the collection cylinder to empty the waste, or remove the fixing bolts to remove the filter element for cleaning or replacement. Step 4: After cleaning or replacing the filter element, align the bottom of the collection cylinder with the slot on the mounting base and place it downwards. Ensure the rubber retaining ring fits tightly against the side wall of the slot, and the magnetic plate will automatically attract and fix the cylinder to the main magnet. Next, slide the two limit brackets to make the vertical rod press against the side wall of the collection cylinder, tighten the locking screw to complete the lateral locking, and restart the device to continue operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention allows the roller brush assembly to effectively gather garbage from different areas of the road surface by cooperating with the oblique sweeping brush and the straight brush roller; the negative pressure suction mechanism establishes negative pressure for the collection cylinder through a power suction pump, and quickly sucks the gathered garbage into the collection system through the adsorption hood and garbage suction pipe. This structure avoids the dust and garbage residue problems that are easily generated by traditional single sweeping methods, and significantly improves the comprehensiveness and cleanliness of garbage collection.

[0016] (2) The present invention uses a main magnet installed in the slot of the fixed seat and a magnetic suction plate installed at the bottom of the collection tube to achieve rapid alignment and adsorption fixation by using magnetic force; at the same time, the interference fit between the rubber retaining ring and the side wall of the slot further enhances the installation stability. This structure makes the collection tube less prone to loosening during operation and easy to separate during maintenance, which greatly improves loading and unloading efficiency and reduces the intensity of manual operation.

[0017] (3) The solution of the present invention can slide and lock along the surface of the fixed seat through the cooperation of the limiting frame, the adjusting groove and the locking screw, which can adapt to the collection tubes of different diameters. The L-shaped design can provide lateral support and is easy to adjust and fix, effectively preventing the collection tube from shifting during vehicle movement or vibration, thus enhancing the reliability and adaptability of the system.

[0018] (4) The present invention, by using a mounting bracket, air filter and rubber ring to install the filter element structure in the waste barrier chamber of the collection cylinder, can effectively intercept the sucked fine dust, prevent it from entering the power suction pump, and extend the service life of the equipment. At the same time, the filter element is connected to the collection cylinder by fixing bolts, which is convenient for individual disassembly, cleaning or replacement, and maintenance is convenient and does not affect other components.

[0019] (5) In the present invention, the collection chamber is divided into an item placement area and an equipment installation area by a partition. The former is equipped with hooks for storing maintenance tools and spare filter cartridges, while the latter is specifically used for installing core components such as collection cylinders and power suction pumps. This structure makes the device layout reasonable and the operating space clear, improving the systematic nature of equipment management and the orderliness of the work site.

[0026] In this embodiment, it should also be noted that the actual dimensions of each component in the application document will be selected and installed according to the actual needs on site. Furthermore, it should be noted that this application document only addresses the shortcomings of existing high-efficiency collection devices for highway pavement pollutants, such as low cleaning and collection efficiency and complex equipment maintenance and repair; it does not involve improvements in other aspects.

[0027] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: When the solution of this invention is used in actual field: A method for using a high-efficiency collection device for highway pavement pollutants includes the following steps: Step 1: On-site personnel transport the device to the section of the highway to be cleaned. By activating the self-propelled assembly 12, the walking wheels 123 begin to rotate. The power gear 122 transmits power through meshing with the synchronous gear 121, driving the walking wheels 123 to propel the entire device forward at a constant speed along the road surface. Simultaneously, the DC servo motor 124 and synchronous motor 113 of the drive roller brush assembly 11 are started, causing the straight brush roller 114 and a pair of oblique sweeping brushes 111 to rotate synchronously, ready for cleaning operations. Step 2: During the movement of the device, the roller brush assembly 11 operates close to the road surface. The oblique sweeping brush 111 is arranged at an angle to sweep the garbage inward from the shoulder and edge areas; the straight brush roller 114 is responsible for pushing the garbage in the central area of ​​the road surface backward. The two work together to effectively gather various pollutants (including large particles and fine dust) to the area directly in front of the adsorption hood 43 behind the sweeping chamber 2; Step 3: Start the power suction pump 42 to establish a stable negative pressure inside the collection cylinder 41 through the power connection pipe 45. The garbage suction pipe 44 connects the adsorption hood 43 to the collection cylinder 41. Under the action of negative pressure, the garbage collected by the roller brush assembly 11 is sucked into the adsorption hood 43 and transported to the garbage barrier chamber 401 inside the collection cylinder 41 through the garbage suction pipe 44. The filter structure 6 set in the garbage barrier chamber 401 can effectively filter fine dust and prevent it from entering the power suction pump 42, while ensuring air circulation and maintaining the continuous and efficient operation of negative pressure adsorption. Step 4: When the waste in the collection cylinder 41 reaches its maximum capacity or needs to be cleaned, first turn off the power suction pump 42 and stop the device from operating. Open the inspection cover 21 and enter the equipment installation area 302. Loosen the locking screws 55 on the two limit brackets 54, allowing the limit brackets 54 to slide along the adjustment groove 501. After releasing the lateral limit on the collection cylinder 41, disconnect the power to the main magnet 51. Pull the collection cylinder 41 upwards; the magnetic suction plate 52 and the main magnet 51 will attract each other, and at the same time, the rubber retainer 53 will disengage from the side wall of the slot 304, allowing the collection cylinder 41 to be removed as a whole. The collection cylinder 41 can then be opened to empty the waste, or the fixing bolts 64 can be removed to remove the filter element structure 6 for cleaning or replacement. Step 4: After cleaning or replacing the filter element, align the bottom of the collection cylinder 41 with the slot 304 on the fixing base 303 and place it downwards. Ensure the rubber retaining ring 53 fits tightly against the side wall of the slot 304; the magnetic plate 52 will automatically attract the main magnet 51, securing the bottom. Next, slide the two limiting brackets 54 so that their vertical rods are flush against the side wall of the collection cylinder 41, tighten the locking screw 55 to complete the lateral locking, and restart the device to continue operation.

[0028] The above-disclosed embodiments are only a few specific examples of the present invention.
