Description

Technical Field

[0001] The utility model relates to the technical field of permeable concrete paving, in particular to a permeable hole anti-clogging cleaning device. Background Art

[0002] Permeable concrete is different from traditional concrete. It is mainly composed of a mixture of aggregate, cement, permeable concrete enhancer and water. Its pores are large and evenly distributed, and water can flow through the pores, thereby achieving water infiltration and collection. This type of concrete can increase the city's permeable and breathable space, and has a good effect on regulating urban climate and maintaining ecological balance.

[0003] It is normal for the permeable holes of permeable concrete pavement to be clogged, and the blockages are shallowly distributed in the permeable concrete pavement, with a depth of no more than 1 cm. In order to ensure the permeability of the pavement, the permeable holes need to be cleaned regularly. The commonly used method now is to use a high-pressure water gun (5MPa-20MPa) to flush the pores to remove the blockages, but this method has a serious problem of water resource waste. Utility Model Content

[0004] The utility model aims to provide a water permeable hole anti-clogging cleaning device, which can avoid a large amount of water resource waste under the premise of cleaning out the blockages in the pores by combining high-pressure water with a vacuum cleaner with water absorption function.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a water-permeable hole anti-clogging cleaning device, including a cart, on which a vacuum cleaner with a water suction function and a water tank are fixedly installed, a cleaning device is fixed to the front end of the cart, the cleaning device includes a suction head, a dust suction chamber is arranged at the bottom of the suction head, the bottom cover of the dust suction chamber is arranged on the ground, and a wear-resistant absorbent cloth is clamped between the bottom and the ground, an air suction port is arranged at the top, the air suction port is connected to the vacuum cleaner through a pipeline, a water spray pipe is arranged around the periphery of the dust suction chamber, high-pressure water spray holes are evenly arranged at the bottom of the water spray pipe, the high-pressure water spray holes face the ground, and the high-pressure water spray holes are connected to the water tank through a high-pressure pump.

[0006] After adopting the above structure, high-pressure water is transported to the high-pressure water spray hole through the high-pressure water spray hole, and then evenly sprayed to the periphery of the dust suction chamber through the high-pressure water spray hole. A wear-resistant absorbent cloth is fixed to the bottom of the dust suction chamber. The wear-resistant absorbent cloth has a certain blocking effect after absorbing water. Therefore, when the vacuum cleaner is started, a certain suction force is formed between the dust suction chamber and the ground. After the shallow layer of the permeable concrete absorbs water, a dynamic temporary water retention zone is formed between the pores of the permeable concrete. When the dust suction chamber generates suction upward, a certain sealing is formed in the pores, so the suction force of the dust suction chamber is increased to ensure that the blockage in the pores is smoothly sucked out; and the fine dust is infiltrated by water, and the suction force between it and the side wall of the pore will also become smaller, thereby facilitating its suction out; and when the high-pressure water is sprayed on the road surface, it infiltrates into the shallow layer of the permeable concrete road surface, and is quickly sucked into the vacuum cleaner by the dust suction chamber, and then re-filtered and used, thereby avoiding the loss of a large amount of water.

[0007] In order to reduce the wear of the wear-resistant absorbent cloth and ensure that the cleaning device reduces friction during the forward movement, the front and rear ends of the dust suction chamber are replaced by rubber rollers instead of the wear-resistant absorbent cloth, and the rolling direction of the rubber rollers is consistent with the forward direction of the cart.

[0008] In order to expand the dust suction effect of the dust suction chamber and allow water and blockages to smoothly enter the air suction port at the top, the dust suction chamber has a trapezoidal structure.

[0009] In order to ensure the stability of suction force at each position of the dust suction chamber, a plurality of suction ports are evenly arranged on the top of the suction head. The plurality of suction ports are connected in parallel to the suction pipe, and the suction pipe is connected to the vacuum cleaner.

[0010] In order to realize backwashing of the suction pipe, a water inlet is provided at one end of the suction pipe, and the water inlet is fixedly connected to the high-pressure pump through a three-way valve.

[0011] In order to realize the lifting function of the cleaning device, when not cleaning, the cleaning device can be lifted and installed on the trolley.

[0012] In order to facilitate mobility, the cart is also equipped with batteries and a trash can.

[0013] In order to prevent the reflection of water, the high-pressure water spray hole is inclined toward the ground, and the inclined direction is toward the direction of the dust suction chamber.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The utility model discloses a device for cleaning water holes to prevent blockage, which solves the technical problem of large amount of water waste when cleaning the blocked water holes of permeable concrete in the prior art. The utility model uses high-pressure water combined with a vacuum cleaner with water absorption function to clean out the blockages in the pores, thus avoiding large amount of water waste.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] The orientations mentioned in this specification are based on the orientations of the water hole anti-clogging cleaning device of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0023] Embodiment 1:

[0024] like Figure 1 and Figure 2 As shown in the figure, a water hole anti-clogging cleaning device includes a cart 1, on which a vacuum cleaner 2 with a water absorption function and a water tank are fixedly installed. The cart 1 includes a base frame 11 and casters installed at the bottom of the base frame 11, and a push handle 12 is provided on one side of the cart 1. By pushing the push handle 12, the cart 1 can be pushed forward. A push box 13 is fixed on the cart 1, and the water tank is fixed in the push box 13.

[0025] like Figure 2 and Figure 3As shown together, a cleaning device 3 is fixed at the front end of the cart 1. The cleaning device 3 includes a suction head 31. A dust suction chamber 311 is provided at the bottom of the suction head 31. The bottom cover of the dust suction chamber 311 is provided on the ground. The dust suction chamber 311 can be circular or rectangular. In this embodiment, in order to increase the coverage area of ​​the dust suction chamber 311 and reduce the volume of the dust suction chamber 311, ensure sufficient suction force, and improve the dust suction effect of the dust suction chamber, the dust suction chamber 311 is a trapezoidal structure. A wear-resistant absorbent cloth 312 is sandwiched between the bottom of the dust suction chamber 311 and the ground. By providing the wear-resistant absorbent cloth 312, when the wear-resistant absorbent cloth 312 absorbs a certain amount of water, it forms a dynamic water film between the wear-resistant absorbent cloth 312 and the ground under the action of water spraying, thereby forming a certain blocking effect, thereby preventing the gas in the dust suction chamber 311 from excessively losing from the gap between the bottom of the dust suction chamber 311 and the ground, thereby causing a reduction in suction force.

[0026] The top of the dust suction chamber 311 is provided with an air inlet 313. In order to ensure the suction force of the air inlet 313 and prevent dust and the like falling into the water permeable hole from smoothly entering the air inlet 313, the height of the air inlet 313 should be reasonably set, preferably 1 to 3 cm, and the air inlet 313 is connected to the vacuum cleaner 2 through a pipe. In this embodiment, in order to ensure the stability of the suction force at each position of the dust suction chamber 311, a plurality of air inlets 313 are evenly arranged on the top of the suction head 31, and the plurality of air inlets 313 are connected in parallel to the suction pipe 34, which is fixed on the top of the suction head 31, and the middle of the suction pipe 34 is connected to the vacuum cleaner 2.

[0027] The dust suction chamber 311 is surrounded by a water spray pipe 32, and high-pressure water spray holes 321 are evenly arranged at the bottom of the water spray pipe 32. The high-pressure water spray holes 321 face the ground. In order to prevent vertical spraying and water flow reflection impact, the high-pressure water spray holes 321 are tilted toward the ground. In order to prevent water from being too far away from the dust suction chamber 311 and causing serious water infiltration, the tilt direction is toward the dust suction chamber 311. The water spray pipe 32 is connected to the water tank through a high-pressure pump.

[0028] In order to regularly clean the air intake pipe 34 and prevent sludge accumulation, a water inlet 341 is provided at one end of the air intake pipe 34 , and the water inlet 341 is fixedly connected to the high-pressure pump through a three-way valve 342 .

[0029] like Figure 4 As shown, the working process of a water hole anti-clogging cleaning device of the utility model is as follows:

[0030] First, use a sanitation sweeper to clean the dust and debris on the permeable concrete pavement, and then use this equipment to clean the permeable holes.

[0031] The high-pressure water is delivered to the water spray pipe 32 by a high-pressure pump, and then evenly sprayed to the periphery of the dust suction chamber 311 through the high-pressure water spray hole 321. The wear-resistant absorbent cloth 312 absorbs water to form a water film, thereby avoiding excessive loss of air pressure in the dust suction chamber 311; the wear-resistant absorbent cloth 312 has good wear resistance, so proper friction will not cause damage during the ground advancement process. When the vacuum cleaner 2 is started, a certain suction force is formed between the vacuum chamber 311 and the ground, and after the shallow layer of the permeable concrete absorbs water, a dynamic temporary water retention zone is formed between the pores of the permeable concrete. When the vacuum chamber 311 generates suction upward, a certain sealing is formed in the pores, thereby increasing the suction force of the vacuum chamber 311 and ensuring that the blockages in the pores are smoothly sucked out; and when the fine dust is infiltrated by water, the suction force between the wet objects and the side walls of the pores will also become smaller, thereby facilitating its suction out; and when the high-pressure water is sprayed onto the road surface, after it infiltrates into the shallow layer of the permeable concrete road surface, it combines with the blockages in the shallow layer of the permeable concrete to form a wet mass, and then the mass is pulled out of the permeable concrete by the rising airflow, forms mud with water, and is quickly sucked into the vacuum cleaner 2 by the vacuum chamber 311, and then is re-filtered and used, thereby avoiding the loss of a large amount of water.

[0032] According to the blockage state of the water permeable hole, the suction pipe 34 is cleaned regularly. When cleaning, the vacuum cleaner 2 is turned off, the water channel connected to the water inlet 341 by the three-way valve 342 is opened, the high-pressure pump is started, and high-pressure water is passed into the suction pipe 34. The high-pressure water is sprayed out from the suction port 313, thereby flushing the suction pipe 34.

[0033] Embodiment 2:

[0034] like Figure 3 and Figure 4 As shown together, the front and rear ends of the dust suction chamber 311 are replaced by rubber rollers 33 instead of the wear-resistant absorbent cloth 312, and the rolling direction of the rubber rollers 33 is consistent with the forward direction of the cart 1. The sliding friction in the first embodiment is changed to rolling friction through the rubber rollers 33, thereby ensuring that the friction of the cleaning device 3 is reduced during the forward process, and when the rubber rollers 33 contact the ground, a certain sealing effect can also be formed.

[0035] Embodiment three:

[0036] like Figure 1 , Figure 2 and Figure 3 As shown together, in order to improve the functionality of the device, when not in use, the cleaning device 3 is raised to avoid constant friction with the ground, so the cleaning device 3 can be installed on the trolley 1 in a liftable manner.

[0037] A plurality of guide rods 35 are fixed to the top of the suction head 31. In this embodiment, four guide rods 35 are provided, which are respectively located at the four corners of the suction head 31. The front end of the trolley 1 is provided with a sliding hole for the guide rods 35 to slide up and down. A push plate 351 is fixed to the top of the guide rods 35. An electric cylinder is fixed to the trolley 1. The output shaft of the electric cylinder fixes the push plate 351. The push plate 351 is pushed up and down by the electric cylinder, thereby realizing the up and down movement of the suction head 31 and the lifting and lowering of the cleaning device 3. In order to avoid interference between the vacuum cleaner 2 and the cleaning device 3, and between the water tank and the water spray pipe 32, the connecting pipes therebetween are flexible pipes.

[0038] In order to facilitate the advancement, no additional energy vehicle is needed to follow, so the cart 1 is also provided with a battery and a trash can.

[0039] The utility model discloses a device for cleaning water holes to prevent blockage, which solves the technical problem of large amount of water waste when cleaning the blocked water holes of permeable concrete in the prior art. The utility model uses high-pressure water combined with a vacuum cleaner with water absorption function to clean out the blockages in the pores, thus avoiding large amount of water waste.

[0040] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
