Description

Technical Field

[0001] The present application relates to the technical field of ground dust removal devices, and in particular to a ground dust removal device for an underground parking lot. Background Art

[0002] With the rapid development of my country's economy, the vehicle ownership rate continues to rise, and the number of underground parking lots has also increased accordingly. If there is a lot of dust on the underground parking lot, the dust raised by vehicles driving by will seriously affect the vision of the following vehicles and pose a safety hazard. Therefore, it is necessary to remove the dust on the road surface in a timely manner.

[0003] Common dust removal systems include road sweepers, wash-sweepers, and vacuum trucks. When a road sweeper is in operation, side brushes located under the vehicle sweep debris from corners from the outside inward toward the main brush's cleaning area. The main brush sweeps the debris toward the suction cup, which continuously draws it into a trash bin. A filtration system filters the dust-laden airflow and exhausts the clean air into the atmosphere. A road sweeper uses high-pressure spray equipment to clean the road surface, then uses high-speed rotary brushes to sweep the washed surface. Finally, a center-mounted or rear-mounted negative pressure suction cup draws the collected debris into the trash bin. Vacuum trucks operate on the same principle as vacuum cleaners, using a centrifugal fan to generate negative pressure inside the enclosure, creating a pressure differential with the outside. This pressure differential generates suction, which is then transmitted along a duct to a dust hood. The hood draws dust from the ground. The collected dust-laden airflow is filtered through a filtration system, leaving the dust inside the enclosure, and clean air is discharged into the atmosphere.

[0004] Specifically for underground parking lots, if a traditional road sweeper is used, the rotating brushes under the vehicle will lift the dust on the ground to the surroundings during operation, which will increase the dust content in the air and is not suitable for underground parking lots. If a washing and sweeping vehicle is used, the high-pressure water flow sprayed by the washing and sweeping vehicle will wet the dust on the ground and flow to low-lying areas under the action of the water flow, which will increase the drainage burden of the underground parking lot. If a traditional pure suction vacuum cleaner is used, the closed environment of the underground parking lot during the vacuuming operation will cause serious noise pollution. At the same time, the space limitations of underground parking lots are not suitable for the use of traditional road sweepers, washing and sweeping vehicles, and vacuum trucks. Therefore, it is necessary to develop a dust removal device for underground parking lots. Summary of the Invention

[0030] Reference Figure 1 The embodiment of the present application provides an underground parking lot ground dust removal device, comprising a dust removal turntable 1, a receiving and processing vehicle 2, a dust receiving soft bag 3, and a flushing water receiving soft bag 4. The dust removal turntable 1 is capable of absorbing dust from the underground parking lot ground and performing self-cleaning. The dust removal turntable 1 is connected to the top of the receiving and processing vehicle 2 via a support portion, and the dust removal turntable 1 can rotate around the fulcrum of the support portion. The receiving and processing vehicle 2 is provided with a dust box 5 and a sewage treatment box 6. The dust box 5 is connected to the dust removal turntable 1 via the dust receiving soft bag 3, and the sewage treatment box 6 is connected to the dust removal turntable 1 via the flushing water receiving soft bag 4.

[0031] Reference Figure 1 and Figure 2 The dust removal turntable 1 includes a mounting frame 11 and two redirecting rollers 12 arranged on the mounting frame 11, a dust removal belt 13, a driving roller 14, a motor 15, a dust brush 16, a high-pressure water spray head 17, a squeezing roller 18 and a dust removal belt guard (not shown in the figure).

[0032] Reference Figure 2 The mounting frame 11 includes two longitudinal bars 118, seven transverse bars, and an arc-shaped operating rod 119. A first transverse bar 111, a second transverse bar 112, a third transverse bar 113, a fourth transverse bar 114, a fifth transverse bar 115, a sixth transverse bar 116, and a seventh transverse bar 117 are sequentially arranged between the two longitudinal bars 118. The first transverse bar 111 is located at the leading end of the longitudinal bars 118, and the arc-shaped operating rod 119 is located at the trailing end of the longitudinal bars 118. The lengths of the first transverse bar 111, the second transverse bar 112, the third transverse bar 113, the fourth transverse bar 114, the fifth transverse bar 115, the sixth transverse bar 116, and the seventh transverse bar 117 can all be 800 mm.

[0033] Support wheels 19 are provided on the outside of the longitudinal bar 118. These wheels prevent the dust belt 13 from being pressed against the parking lot floor after the dust removal turntable 1 is tilted. Specifically, the ends of the first crossbar 111 can extend outward and pass through the longitudinal bar 118. The two support wheels 19 are mounted on each end of the first crossbar 111. For ease of installation, the two end extensions of the first crossbar 111 are rectangular parallelepiped structures, and the two support wheels 19 are mounted on the rectangular parallelepiped structures. When the embodiment of the present application is in operation, the two support wheels 19 are in contact with the ground.

[0034] Reference Figure 1 and Figure 2The bottom of the second crossbar 112 is provided with a support rod 110, which is rotatably connected to the receiving and processing vehicle 2 via a bearing (not shown). The ends of the seventh crossbar 117 are connected to arc-shaped operating rods 119, and the end of the arc-shaped operating rod 119 away from the longitudinal rod 118 is tilted downward and abuts against the receiving and processing vehicle 2.

[0035] One of the bend rollers 12 is connected to the first crossbar 111, and the other bend roller 12 is connected to the seventh crossbar 117. A dust removal belt 13 is tensioned between the two bend rollers 12. The dust removal belt 13 is an annular structure and is placed in close contact with the surfaces of the two bend rollers 12. The other side of the dust removal belt 13 that does not contact the bend rollers 12 is provided with plush. When the embodiment of the present application is in operation, the plush on the surface of the dust removal belt 13 contacts the ground. When the dust removal belt 13 rotates, the plush on the surface of the dust removal belt 13 absorbs and wipes dust from the ground.

[0036] The driving roller 14 is connected to the third crossbar 113, and the driving roller 14 contacts the dust removal belt 13 and drives the dust removal belt 13 to rotate. The motor 15 is connected to the fourth crossbar 114, and the motor 15 drives the driving roller 14 to rotate through a chain.

[0037] The dust brush 16 is suspended from the third crossbar 113, the high-pressure water spray head 17 is suspended from the fifth crossbar 115, and the squeezing roller 18 is suspended from the sixth crossbar 116. Thus, the dust brush 16, high-pressure water spray head 17, and squeezing roller 18 are all located below the dust removal belt 13, and are arranged sequentially along the direction of travel of the dust removal belt 13. As the dust removal belt 13 rotates, the dust brush 16 first removes dust particles from the fleece and transfers them to the dust collecting bag 3. Then, the high-pressure water spray head 17 sprays water onto the fleece on the dust removal belt 13, removing the dust from the fleece as the belt 13 rotates. Finally, the squeezing roller 18 squeezes the fleece on the dust removal belt 13, removing the sprayed water. This completes the self-cleaning of the dust removal belt 13.

[0038] In addition, the dust removal belt shield is fixed on the second cross bar 112 and the seventh cross bar 117 and covers the dust removal belt 13 to protect the dust removal belt 13 and intercept water thrown out when the dust removal belt 13 rotates.

[0039] Reference Figure 3The receiving and processing vehicle 2 includes a frame 21, two front wheels 22 and a steering rear wheel 23. In addition to the dust box 5 and the sewage treatment tank 6, the frame 21 is also provided with a high-pressure water pump (not shown in the figure) and a battery (not shown in the figure). The inlet of the high-pressure water pump is connected to the sewage treatment tank 6, and the outlet is connected to the high-pressure water spray head 17. The battery supplies power to electrical equipment such as the motor 15. The frame 21 includes an operating shaft 211, a handle 212, a fixed horizontal shaft 213, a connecting horizontal shaft 214, a support shaft 215 and a connecting longitudinal shaft 216. The support shaft 215 is located at the head of the frame 21, and the operating shaft 211 is located at the tail of the frame 21, and the two are arranged in parallel. The connecting longitudinal shaft 216 is an identical double shaft with a length of 1000 to 2500 mm, preferably 2000 mm. The rear ends of the two connecting longitudinal shafts 216 are welded to the operating shaft 211, and the front ends are welded to the support shaft 215. The fixed transverse axis 213 and the connecting transverse axis 214 are respectively welded between the two connecting longitudinal axes 216 .

[0040] The length of the operating shaft 211 is 500 to 1500 mm, preferably 1200 mm. When the embodiment of the application itself is in the transport state, the arc-shaped operating rod 119 abuts against the operating shaft 211. The operating shaft 211, the fixed horizontal shaft 213, the connecting horizontal shaft 214, the support shaft 215 and the connecting longitudinal shaft 216 are all made of stainless steel pipes. The handle 212 is cylindrical with a hole at one end and a thickness of 2 to 4 mm, preferably 4 mm. The length is 100 to 180 mm, preferably 100 mm, and is divided into two left and right parts, which are respectively sleeved on the two ends of the operating shaft 211, and there is no relative rotation between the handle 212 and the operating shaft 211. The handle 212 is made of black rubber.

[0041] Two rolling bearings (not shown) are mounted on support shaft 215, which is fixedly connected to the inner races of both rolling bearings. The lower ends of the two support rods 110 on dust removal turntable 1 are welded to the outer races of their respective rolling bearings, allowing dust removal turntable 1 to rotate around the rolling bearings.

[0042] The support shaft 215 also has several fixing holes at both ends. The front wheels 22 are tire-type and are mounted on the fixing holes at both ends of the support shaft 215. This allows for an adjustable distance between the two front wheels 22. The mounting holes can be selected based on the size of the underground parking space and the location of the front wheels 22.

[0043] The rear wheel 23 is steered to a tire-type universal wheel structure, and the central rotating shaft of the rear wheel 23 is welded to the middle position of the connecting transverse axis 214 by an upright steel bar. Thus, the rear wheel 23 is steered to support and turn to.

[0044] The dust box 5 is installed between the support shaft 215 and the fixed horizontal shaft 213, and the dust box 5 is located below the dust brush 16. The upper end of the dust receiving soft bag 3 is connected to the third horizontal bar 113, and the lower end is connected to the entrance of the dust box 5.

[0045] The sewage treatment tank 6, high-pressure water pump, and battery are all installed between the fixed horizontal axis 213 and the connecting horizontal axis 214, and the sewage treatment tank 6 is located below the squeezing roller 18. The upper end of the flushing water receiving soft bag 4 is connected to the sixth horizontal bar 116, and the lower end is connected to the inlet of the sewage treatment tank 6.

[0046] Reference Figure 4 The sewage treatment tank 6 is divided into a flotation chamber 61, a sedimentation chamber 62, a filter chamber 63 and a clean water chamber 64 which are connected in sequence. The sedimentation chamber 62 is located between the flotation chamber 61 and the filter chamber 63, and the clean water chamber 64 is located below the filter chamber 63.

[0047] Specifically, a water inlet pipe 65 is provided on the side wall of the flotation chamber 61. A flotation plate 66 is located in the middle of the chamber 61, positioned below the water inlet pipe 65. The flotation plate 66 is connected to a flotation blower 67 outside the chamber 61 via a pipe. Several scum troughs 68 are arranged from top to bottom along the walls of the flotation chamber 61. Filter bags (not shown) are installed in the scum troughs 68. The lower portion of the flotation chamber 61 is provided with an inclined bottom plate 611. Wastewater treated by flotation flows along the inclined bottom plate 611 into the lower middle portion of the sedimentation chamber 62.

[0048] A baffle 69 is provided between the flotation chamber 61 and the sedimentation chamber 62. The lower portion of the baffle 69 is provided with a 45-degree corner, which turns toward the side of the flotation chamber 61. The bottom of the sedimentation chamber 62 is designed as a conical structure, and a sediment discharge valve 610 is provided at the lower portion of the conical structure.

[0049] A partition 612 is provided between the sedimentation chamber 62 and the filter chamber 63 . A filter material 613 is provided in the middle of the filter chamber 63 . The filter material 613 is made of quartz sand and is placed on a filter material rack.

[0050] Thus, the sewage to be treated enters the sedimentation chamber 62 after suspended matter is removed from the flotation chamber 61 , enters the filtration chamber 63 after sediment is removed from the sedimentation chamber 62 , and enters the clean water chamber 64 after being filtered in the filtration chamber 63 .

[0051] A motor switch button, a high-pressure water pump switch button and an air flotation blower switch button are also provided on the operating shaft 211 of the vehicle frame 21. The battery is connected to the motor 15, the high-pressure water pump, the air flotation blower 67 and each switch button via a cable.

[0052] The water inlet of the high-pressure water pump is connected to the clean water chamber 64, and the water outlet of the high-pressure water pump is connected to the high-pressure water spray head 17. Therefore, the purified sewage is sucked by the high-pressure water pump and then cleans the dust removal belt 13 again, thereby realizing the recycling of sewage.

[0053] The dust collecting bag 3 is a rectangular parallelepiped structure with upper and lower openings. The upper portion of the dust collecting bag 3 is suspended on the third crossbar 113 to receive dust particles brushed off by the dust brush 16. The lower portion of the dust collecting bag 3 is embedded in the upper opening of the dust box 5. The dust collecting bag 3 is made of rubber.

[0054] The flushing water receiving bag 4 is also a rectangular parallelepiped structure with openings at the top and bottom. The upper portion of the flushing water receiving bag 4 is suspended from the fifth and sixth crossbars 115, 116 to receive the spray water from the plush. The lower portion of the flushing water receiving bag 4 is connected to the water inlet pipe 65 of the flotation chamber 61. The flushing water receiving bag 4 is made of rubber.

[0055] The operation process of the underground parking lot ground dust removal device in the embodiment of the present application is as follows:

[0056] 1. Select different fixing holes according to the size of the operating space in the underground parking lot and adjust the distance between the two front wheels 22.

[0057] 2. Start the motor 15 , the high-pressure water pump and the flotation blower 67 . The motor 15 drives the driving roller 14 and the dust removal belt 13 to rotate, and the high-pressure water spray head 17 sprays the dust removal belt 13 .

[0058] 3. Lift the arc-shaped operating lever 119 to make the support wheel 19 contact the ground. The support wheel 19 plays a supporting role to prevent the dust removal belt 13 from being crushed. The plush on the surface of the dust removal belt 13 contacts the ground. As the dust removal belt 13 rotates, the plush on the surface of the dust removal belt 13 absorbs and wipes the dust on the ground.

[0059] 4. The dust brush 16 intercepts and brushes the dust particles on the plush, which fall into the dust box 5 through the dust receiving soft bag 3. The dust on the plush of the dust removal belt 13 is sprayed and removed by high-pressure water. The spray water and the dirty water squeezed out by the squeezing roller 18 enter the flotation chamber 61 through the flushing water receiving soft bag 4 and the water inlet pipe 65.

[0060] 5. The flotation disc 66 generates a large number of tiny bubbles that adhere to the suspended matter to form a mixture. Under the action of buoyancy, the bubbles rise to the water surface and enter the scum tank 68. As the water level drops, they are intercepted by the filter bag. Then the wastewater enters the sedimentation chamber 62. The sediment sinks to the lower part of the sedimentation chamber 62 under the action of gravity and is discharged through the sediment discharge valve 610 at the bottom. The wastewater enters the filter chamber 63, is filtered by the filter material 612, and then enters the clean water chamber 64.

[0061] 6. The water in the clean water chamber 64 is pumped into the high-pressure water spray head 17 through the water pipe by the high-pressure water pump for recycling.

[0062] 7. Push the receiving and processing vehicle 2 to change the dust removal position.

[0063] 8. When the water level in the sewage treatment tank 6 is lower than the set height, water needs to be added and the scum in the scum tank 68 needs to be cleared.

[0064] 9. When the operation is completed, stop the motor 15, the high-pressure water pump and the flotation blower 67, pull the arc-shaped operating rod 119 to disengage the support wheel 19 from the ground, and place the arc-shaped operating rod 119 on the operating shaft 211. The dust removal turntable 1 is placed flat on the receiving and processing vehicle 2 through the support of the support rod 110 and the arc-shaped operating rod 119.

[0065] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
