[0001] The present invention belongs to the technical field of environmental sanitation cleaning, and more specifically, relates to a rotary road cleaning unit and a road cleaning device. Background Art

[0002] In places such as urban roads, community streets, parks, etc., it is necessary to use environmental sanitation cleaning vehicles to clean the roads and recycle the dust on the road surface. For example, cement roads, asphalt roads, etc. Since it is easy for sediment, miscellaneous dust, etc. to accumulate on the road surface, simply using a brush to clean or a vacuum cleaner to suck is difficult to achieve a high cleaning effect, and it is easy to cause problems such as road surface environmental dust.

[0003] Based on this, a cleaning method of spraying water on the road surface to recycle sediment and miscellaneous dust has emerged to reduce road surface environmental dust. The traditional road cleaning mechanism uses a water spray head arranged in the traveling direction to spray water on the road surface, and uses the rebound impact force of the water sprayed on the road surface to recover the water flow carrying dust into the recovery water tank through a diversion plate, thereby realizing the dual recovery of water and dust.

[0004] The inventor found during the research process that the traditional road cleaning mechanism has a relatively good recovery effect during the traveling process, but when staying in place, it is easy to leave more water stains in place and the recovery effect is relatively poor.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0043] Please refer to Figures 1 to 7 , and now the rotary road cleaning unit 1 and the road cleaning device provided by the embodiments of the present invention will be described.

[0044] Please refer to Figures 1 to 3 , the embodiments of the present invention provide a rotary road cleaning unit 1, including: a mounting bracket 100; a rotating assembly 200 disposed on the mounting bracket 100; a plurality of water spraying assemblies 300, each water spraying assembly 300 includes a recovery water tank 320 having a flow guide plate 310 and connected to the rotating assembly 200, and a water spraying head group 330 connected to the recovery water tank 320. The water spraying direction of the water spraying head group 330 and the plane where the flow guide plate 310 is located are both arranged at an angle with the road surface; a water supply pipeline 400 communicated with a plurality of water spraying head groups 330; and a water collection pipeline 500 communicated with a plurality of recovery water tanks 320; when cleaning the road surface, the rotating assembly 200 can drive the recovery water tank 320, the water spraying head group 330, the water supply pipeline 400 and the water collection pipeline 500 to rotate together.

[0045] It should be noted that the rotary road cleaning unit 1 provided in the embodiments of the present invention can be applied to road cleaning devices such as municipal sanitation vehicles for urban roads, community streets, parks and other places, and can also be applied to road cleaning devices for factory roads, airport runways and other places. In addition, the rotary road cleaning unit 1 is not limited to cleaning the road surface, and can also be the structural surface of other equipment, and its scope of use and protection scope are not limited by the name. In the description herein, the traveling direction refers to the moving direction of the road cleaning device. In the description herein, the road surface is taken as an example for illustration.

[0046] Specifically, the cleaning working principle in the embodiments of the present invention is as follows: the water spraying direction of the water spraying head group 330 and the plane where the guide plate 310 is located are both arranged at an angle with the road surface. The water spraying head group 330 sprays water on the road surface, and uses the rebound impact force of the water flow to return the water flow carrying dust to the recovery water tank 320 through the guide plate 310, which can not only clean the dust but also recover the water flow. As Figure 5 shown, the water spraying head group 330 includes a plurality of sub-water spraying heads and a water spraying main pipe. The water spraying head group 330 is connected to the recovery water tank 320 through the connection structure 340 provided at both ends of the water spraying main pipe, and angle rotation mechanisms are provided at both ends of the water spraying main pipe to enable the water spraying main pipe to adjust its angle relative to the connection structure 340, and further adjust the included angle between the sub-water spraying heads and the ground.

[0047] The mounting seat 100 is used to carry the rotating assembly 200, the water spraying assembly 300, the water supply pipeline 400 and the water collection pipeline 500, and can be hoisted on the moving vehicle body of the road cleaning device. The water supply pipeline 400 is used to connect to the high-pressure water supply tank to provide the required water for the water spraying head group 330. The high-pressure water supply tank can be arranged on the moving vehicle body of the road cleaning device, can also be fixed at the cleaning site, or can be a portable mobile water tank. The water collection pipeline 500 is used to connect to the high-pressure water extraction tank to collect water from the recovery water tank 320. The high-pressure water extraction tank can be arranged on the moving vehicle body of the road cleaning device, can also be fixed at the cleaning site, or can be a portable mobile water tank. It can be understood that in order to realize the water circulation, the high-pressure water supply tank and the high-pressure water extraction tank are in a connected relationship.

[0048] When cleaning the road surface, the rotating assembly 200 drives the water spraying assembly 300, the water supply pipeline 400 and the water collection pipeline 500 to move together, avoiding the situation that the water flow leaks and accumulates in place due to continuous impact on the same location, improving the recovery effect and reducing the waste of water resources.

[0049] The rotary road cleaning unit 1 provided by the embodiment of the present invention has at least the following technical effects: Compared with the traditional technology, the rotary road cleaning unit 1 provided by the embodiment of the present invention can install the rotary assembly 200 and multiple water spraying assemblies 300 together through the installation support 100 to play a bearing role. In the water spraying assembly 300, the water carrying dust is recycled from the diversion plate 310 to the recycling water tank 320 by the water spraying and rebounding force of the water spraying head group 330. The required water is provided for the water spraying head group 330 through the water supply pipeline 400, and the water in the recycling water tank 320 is recycled through the water collection pipeline 500. When cleaning the road surface, the rotary assembly 200 can drive the water spraying assembly 300, the water supply pipeline 400 and the water collection pipeline 500 to rotate together, avoiding the situation that when staying in place, the water spraying head group 330 continuously impacts the same location, causing water leakage and accumulation in place to form more water stains. And multiple water spraying assemblies 300 increase the cleaning range and comprehensiveness, and improve the recycling effect.

[0050] There is no limitation on the specific composition of the installation support 100. The following is an example. Please refer to Figures 1 to 3 , in some possible embodiments, multiple water spraying assemblies 300 are arranged around the rotary assembly 200 at intervals. The installation support 100 includes: a circumferential protection cover 110, which is disposed outside the contour formed by the multiple water spraying assemblies 300; an installation bearing plate 120, both ends of which are connected to the inner wall of the circumferential protection cover 110, and the rotary assembly 200 is disposed on the installation bearing plate 120; and an end face protection cover 130, which is stacked on the installation bearing plate 120 and covers the edge of the circumferential protection cover 110.

[0051] Specifically, the multiple water spraying assemblies 300 are rotationally arranged at equal intervals, which can improve the stability during rotation. On this basis, the installation support 100 includes a circumferential protection cover 110, an installation bearing plate 120 and an end face protection cover 130. Among them, the circumferential protection cover 110 can protect the outer circle contour formed by the multiple water spraying assemblies 300 to prevent mechanical damage caused by other obstacles. The end face protection cover 130 can protect the radial contour formed by the multiple water spraying assemblies 300 to prevent mechanical damage caused by other obstacles. The installation bearing plate 120 can be fixed to the inner wall of the circumferential protection cover 110 by welding, clamping, etc., and play a bearing role for the rotary assembly 200, the water spraying assembly 300, the water supply pipeline 400 and the water collection pipeline 500.

[0052] Of course, in other possible embodiments, the installation support 100 may not be provided with the circumferential protection cover 110 and may not be provided with the end face protection cover 130.

[0053] In order to realize the diversity of the use of the rotary road cleaning unit 1, please refer to Figure 2, in some possible embodiments, the mounting support 100 further includes: a hanging lug 140 connected to the side of the mounting carrier plate 120 facing away from the water spraying assembly 300 and passing through the end face protection cover 130; a hand-pushing wheel 150 mounted on the circumferential protection cover 110; and a hand-pushing armrest 160 detachably connected to the circumferential protection cover 110.

[0054] Specifically, multiple hanging lugs 140 can be provided, for example, two, three, four, etc. in number, to achieve force balance. The hanging lugs 140 can be integrally formed by the mounting carrier plate 120 or fixed to the mounting carrier plate 120 by welding. The hanging lugs 140 can hang the rotary road cleaning unit 1 under the frame of the moving vehicle body. It can be understood that when the end face protection cover 130 is fixed to the mounting carrier plate 120, the hanging lugs 140 can also be directly provided on the end face protection cover 130.

[0055] Multiple hand-pushing wheels 150 can be provided, for example, two, three, four, etc. in number, to achieve smooth movement when pushing the rotary road cleaning unit 1. The hand-pushing wheels 150 can be one-way wheels, universal wheels, etc. The rotary road cleaning unit 1 can be removed from the moving vehicle body, and by pushing it to move on the road surface, cleaning operations can be carried out in some areas with small spaces, making the cleaning range more comprehensive and avoiding the situation where it is difficult to clean due to the too large moving vehicle body.

[0056] The hand-pushing armrest 160 is connected to the circumferential contour of the circumferential protection cover 110 by means of plugging, threaded connection, clamping, etc. After the rotary road cleaning unit 1 is removed from the moving vehicle body, it is convenient to move and change the position of the rotary road cleaning unit 1, making it more convenient to use. With such a setting, the multi-functional use mode of the rotary road cleaning unit 1 can be realized, improving the convenience in practical applications.

[0057] For the convenience of installing the hand-pushing wheels 150 and the hand-pushing armrest 160, please refer to Figure 2 , in some possible embodiments, the mounting support 100 further includes a fixing rod 170 surrounding and connected to the outside of the circumferential protection cover 110. Both the hand-pushing wheels 150 and the hand-pushing armrest 160 are provided on the fixing rod 170. Specifically, the fixing rod 170 is arc-shaped, surrounds the circumferential contour of the circumferential protection cover 110, and is fixed to the circumferential protection cover 110 by means of welding, threaded connection, clamping, sleeving, etc. With such a setting, it is convenient to install the hand-pushing wheels 150 and the hand-pushing armrest 160. The hand-pushing wheels 150 can be connected to the wheel seat through fixing rings sleeved on the fixing rod 170. For example, three fixing rings are provided at intervals on the fixing rod 170, and correspondingly three hand-pushing wheels 150 are provided.

[0058] The specific composition of the rotating assembly 200 is not limited, and is described below by way of example. Figure 1 , Figure 3 and Figure 4 In some possible embodiments, the rotating assembly 200 includes: a rotating motor 210, which is disposed on the mounting support 100; a driving gear 220, which is connected to the rotating motor 210; a driven gear 230, which is meshed with the driving gear 220; and a rotating bearing structure 240, which is penetrated and limited to the mounting support 100, is sleeved with the driven gear 230, and is connected to multiple recovery water tanks 320.

[0059] Specifically, the rotary motor 210 can be a pneumatic motor or a hydraulic motor. Compared with the electric motor, the rotary motor 210 has better rotation stability and can make the rotation process of the water spray assembly 300 more stable. The rotary motor 210 is specifically arranged on the side of the mounting plate 120 away from the water spray assembly 300, and its output shaft passes through the mounting plate 120, is connected to the driving gear 220, and drives the rotation of the driving gear 220. The driven gear 230 is sleeved on the rotating bearing structure 240. When the driving gear 220 drives the driven gear 230 to rotate, the driven gear 230 drives the rotating bearing structure 240 to rotate together. The rotating bearing structure 240 is specifically penetrated and limited to the mounting plate 120, and is connected to multiple recovery water tanks 320, and is used to carry the water spray assembly 300, the water supply pipeline 400 and the water collection pipeline 500.

[0060] The specific composition of the rotating bearing structure 240 is not limited, and is described below by way of example. Figure 6 and Figure 7 In one embodiment, the rotating bearing structure 240 includes: a bearing sleeve 241, which is inserted into the mounting support 100, is sleeved with a driven gear 230, and is connected to multiple recovery water tanks 320; a first retaining ring 242, which is sleeved on the bearing sleeve 241 and is limited to the side of the mounting support 100 away from the water spraying assembly 300; a second retaining ring 243, which is sleeved on the bearing sleeve 241 and is limited to the side of the mounting support 100 adjacent to the water spraying assembly 300; and a double-headed rotating joint 244, which is accommodated in the bearing sleeve 241, wherein the water supply pipeline 400 and the water receiving pipeline 500 respectively have a water supply joint 410 and a water receiving joint 510 that are inserted into the bearing sleeve 241 and extend through the double-headed rotating joint 244.

[0061] Specifically, the bearing sleeve 241 and the driven gear 230 may be connected indirectly or directly, and the bearing sleeve 241 and the recovery water tank 320 may be connected indirectly or directly, and there is no limitation on this.

[0062] The first clamping ring 242 and the second clamping ring 243 are respectively located on the upper and lower sides of the mounting support 100, specifically on the upper and lower sides of the mounting carrier plate 120, and can axially limit the bearing sleeve 241. Moreover, the first clamping ring 242 has a bearing effect on other components of the rotating bearing structure 240, and thus has a bearing effect on the water spraying assembly 300, the water supply pipeline 400, and the water collection pipeline 500.

[0063] The first clamping ring 242 can specifically be a combination of a round nut and a lock washer. During use, the inner tongue of the lock washer is inserted into the bearing sleeve 241, and the outer tongue of the lock washer is inserted into the round nut, thereby realizing the fixed connection between the round nut and the bearing sleeve 241. The round nut and the lock washer are beneficial for bearing a large axial force. Similarly, the second clamping ring 243 can specifically be a combination of a round nut and a lock washer, and the usage mode is the same as that of the first clamping ring 242, which will not be elaborated here. Of course, the first clamping ring 242 and the second clamping ring 243 can also adopt other structures. For example, they can be ordinary ring-shaped structures with inner and outer edges, etc.

[0064] The bearing sleeve 241, the first clamping ring 242, the second clamping ring 243, and the double-headed rotary joint 244 rotate together under the action of the driven gear 230, the water supply pipeline 400, and the water collection pipeline 500. The water supply pipeline 400 and the water collection pipeline 500 respectively have a water supply joint 410 and a water collection joint 510 that are arranged through the bearing sleeve 241 and extend out through the double-headed rotary joint 244, with higher structural compactness and less messy pipelines. It can be understood that there is no friction or less friction between the bearing sleeve 241 and the mounting carrier plate 120; there is less friction between the first clamping ring 242 and the mounting carrier plate 120; there is no friction or less friction between the second clamping ring 243 and the mounting carrier plate 120, so the influence on the rotation process is small. Of course, lubricating oil can also be applied between the bearing sleeve 241, the first clamping ring 242, the second clamping ring 243, and the mounting carrier plate 120.

[0065] To facilitate the installation and fixation of the recovery water tank 320, please refer to Figure 6 and Figure 7 , in some possible embodiments, the rotating bearing structure 240 further includes: a connecting sleeve 245, sleeved on a part of the bearing sleeve 241 adjacent to the water spraying assembly 300, and the driven gear 230 is sleeved thereon; a first ring plate 246, sleeved on the connecting sleeve 245; and a second ring plate 247, arranged at an interval from the first ring plate 246 and sleeved on the connecting sleeve 245. The first ring plate 246 and the second ring plate 247 together form a receiving space for clamping the recovery water tank 320.

[0066] Specifically, the connecting sleeve 245 can be directly sleeved and connected to the bearing sleeve 241, or can be sleeved and connected to the bearing sleeve 241 through the bearing 248. The connecting sleeve 245 can better match the driven gear 230 to ensure rotational stability. There is an interference fit between the connecting sleeve 245 and the driven gear 230, and relative rotation between the two is not allowed.

[0067] The first ring plate 246 can be fixed to the connecting sleeve 245 by means such as welding or integral formation to improve the reliability of nesting. Similarly, the second ring plate 247 can also be fixed to the connecting sleeve 245 by means such as welding or integral formation to improve the reliability of nesting, so that the first ring plate 246, the second ring plate 247 and the connecting sleeve 245 rotate together.

[0068] The axial height of the accommodation space formed by the first ring plate 246 and the second ring plate 247 is consistent with the outer shape thickness of the recovery water tank 320 in this space. The first ring plate 246 and the second ring plate 247 are respectively fixed to the top edge and the bottom edge of the recovery water tank 320 by means such as welding or threaded connection. During rotation, the driven gear 230 drives the connecting sleeve 245, the first ring plate 246, the second ring plate 247 and the recovery water tank 320 to rotate together. And since the water supply pipeline 400 and the water collection pipeline 500 are passed through the bearing sleeve 241 and extended through the double-headed rotary joint 244, therefore, the water supply pipeline 400, the water collection pipeline 500, the bearing sleeve 241, the first clamping ring 242, the second clamping ring 243 and the double-headed rotary joint 244 also rotate together.

[0069] Please refer to Figure 1 、 Figure 3 and Figure 4 In some possible embodiments, a plurality of water spraying assemblies 300 are arranged around the rotating assembly 200 at intervals. Both the water supply pipeline 400 and the water collection pipeline 500 are arranged in a ring shape and are located between the mounting support 100 and the water spraying assemblies 300. The water supply pipeline 400 has a plurality of water supply branch pipes communicating with the corresponding water spray head groups 330, and the water collection pipeline 500 has a plurality of water collection branch pipes communicating with the corresponding recovery water tanks 320. And the water supply pipeline 400 and the water collection pipeline 500 respectively have a water supply joint 410 and a water collection joint 510 extending from the rotating assembly 200.

[0070] In this embodiment, the water supply pipeline 400 and the water collection pipeline 500 are nested and arranged at intervals in the direction outward from the rotation center in the same plane or different planes to avoid spatial interference, making the overall structure more compact and coordinated, and uniformly supplying water required for a plurality of water spray head groups 330 and uniformly collecting water from a plurality of recovery water tanks 320.

[0071] Specifically, the water supply pipeline 400 has a water supply branch corresponding to each sprinkler head group 330, and the water collection pipeline 500 has a water collection branch corresponding to each water collection tank 320, so as to uniformly supply and collect water correspondingly. To improve the compactness and integrity of the overall structure and reduce complicated cross pipelines, the water supply pipeline 400 and the water collection pipeline 500 also respectively have a water supply joint 410 and a water collection joint 510 extending from the rotating assembly 200. The water supply joint 410 and the water collection joint 510 rotate together with the rotating assembly 200 and directly extend from the rotating assembly 200, without the need to open or design other passing structures on the installation support 100. The specific passing method is the same as the content of the rotating assembly 200 in the above embodiment, which will not be elaborated here.
