Description

Technical Field

[0001] This application relates to the field of environmental sanitation technology, and in particular to a sanitation vehicle. Background Technology

[0002] Currently, water trucks are frequently used for road cleaning during environmental sanitation operations. This involves spraying water to wash the road surface for cleaning. However, after washing, some water remains on the road surface because the ground is not completely flat and the drainage outlets are spaced far apart in some areas. This can cause water accumulation or secondary pollution.

[0003] Regarding the aforementioned technologies, existing sanitation vehicles typically only have a water spraying system for washing or a sweeping system for cleaning road garbage, and cannot absorb and clean up the water that accumulates on the ground after washing, thus having poor applicability. Summary of the Invention

[0004] In order to facilitate the cleaning and collection of some of the water that accumulates on the ground after rinsing and reduce secondary pollution caused by the water, this application provides a sanitation vehicle.

[0005] The sanitation vehicle provided in this application adopts the following technical solution:

[0006] A sanitation vehicle includes: a vehicle body; an absorption roller rotatably disposed at the rear of the vehicle body, with multiple absorption rollers spaced apart along the width direction of the vehicle body, the rotation axis of the absorption rollers being arranged along the width direction of the vehicle body, and a flexible water-absorbing element wrapped around the outer side of the absorption rollers, the flexible water-absorbing element making rolling contact with the ground; a mounting part rotatably disposed at the rear of the vehicle body, the rotation axis of the mounting part being arranged along the width direction of the vehicle body, a first driving member disposed on the vehicle body for driving the mounting part to rotate and adjust, and the absorption rollers rotatably disposed at the mounting part; a water-squeezing assembly disposed at the rear of the vehicle body, the water-squeezing assembly for squeezing and dewatering the flexible water-absorbing element; and a collection assembly disposed on the vehicle body, the collection assembly for collecting the water squeezed out by the flexible water-absorbing element.

[0007] By adopting the above technical solution, when the sanitation vehicle moves slowly and washes the ground, some water will accumulate on the ground. When the sanitation vehicle is moving, the absorption roller at the rear of the vehicle body can roll and rub against the ground. Since the flexible water-absorbing component is wrapped around the outside of the absorption roller, it can absorb the water remaining on the ground after washing, reducing the water accumulation on the ground after washing. After the flexible water-absorbing component has absorbed water for a period of time, the first drive component can drive the mounting part to rotate upward, causing all the absorption rollers to lift upward and leave the ground. Then, the squeezing component squeezes and dehydrates the flexible water-absorbing component, ensuring the water absorption function of the flexible water-absorbing component. The water is then collected by the collection component, making it easy to clean and collect the water that has accumulated on the ground after washing, reducing secondary pollution caused by water accumulation.

[0008] In addition, when the absorption roller is raised, a gap is created between the absorption roller and the ground. This allows some of the debris that was blocked on the side of the absorption roller facing the front of the vehicle body to remain in place. At the same time, it reduces the impact of some ground protrusions on the passage of the absorption roller, ensuring that the absorption roller can pass normally over some road surfaces with protrusions when the vehicle is moving.

[0009] Preferably, the dewatering assembly includes an upper pressure part, a lower pressure part, and a second driving member. One side of the upper pressure part and the lower pressure part are rotatably connected to the vehicle body. The upper pressure part and the lower pressure part are arranged opposite each other and their rotating sides are close to each other. The upper pressure part and the lower pressure part rotate synchronously in a direction that moves closer to each other or further away from each other. The second driving member is used to drive the upper pressure part and the lower pressure part to rotate synchronously. When the upper pressure part and the lower pressure part gradually approach each other, a squeezing chamber is formed between the upper pressure part and the lower pressure part. The opposing sides of the upper pressure part and the lower pressure part squeeze the flexible absorbent.

[0010] By adopting the above technical solution, when it is necessary to squeeze the flexible absorbent, the mounting part is rotated upward, which drives each absorbent roller to rotate upward and leave the ground. Then, the second driving part drives the upper and lower pressing parts to rotate and approach each other to form a squeezing chamber, and gradually squeezes the flexible absorbent to achieve squeezing and dehydration of the flexible absorbent. Finally, the upper and lower pressing parts are rotated in a direction away from each other, and the mounting part drives the absorbent rollers back to the position in contact with the ground.

[0011] Preferably, both the upper pressing part and the lower pressing part have grooves on their opposing sides, and the bottom of the grooves is arc-shaped. When the upper pressing part and the lower pressing part approach each other and squeeze water out of the flexible absorbent, a squeezing cavity is formed between the opposing grooves on the upper pressing part and the lower pressing part, and the absorbent roller is located in the squeezing cavity. When the upper pressing part and the lower pressing part rotate in a direction away from each other, the upper pressing part and the lower pressing part leave the path of the absorbent roller as the mounting part rotates.

[0012] By adopting the above technical solution, when the upper pressing part and the lower pressing part approach each other, the grooves of the upper pressing part and the lower pressing part can form a squeezing chamber, and the bottom of the groove can better squeeze the flexible water-absorbing part; and when the upper pressing part and the lower pressing part rotate in a direction away from each other, the upper pressing part and the lower pressing part leave the path of the absorption roller as the mounting part rotates, which can ensure that the absorption roller is not affected by the lower pressing part and the upper pressing part when rotating into or leaving the squeezing chamber.

[0013] Preferably, the pressing part and the side facing each other are provided with a surrounding plate. The pressing part and the pressing part are hollow shells. Water guide holes are provided on the side facing each other and at the bottom of the groove. The water guide holes communicate with the interior of the pressing part or the pressing part. The collection assembly includes a flexible pipe connected to the bottom of the pressing part and a water collection tank on the vehicle body. The flexible pipe communicates with the water collection tank. Water in the pressing part flows freely to the water collection tank through the flexible pipe.

[0014] By adopting the above technical solution, when the upper pressure section and the lower pressure section are close to each other, some water is directly squeezed from the water guide hole into the upper pressure section, and then flows from the upper pressure section into the lower pressure section under the action of gravity. Finally, the water in the lower pressure section is transported to the water collection tank by the flexible pipe. The enclosure can restrict water from flowing out of the surfaces of the upper and lower pressure sections to the ground.

[0015] Preferably, when the upper pressing part and the lower pressing part are rotated to their closest positions, the upper pressing part is located directly above the lower pressing part, and there is a gap between the opposing sides of the upper pressing part and the lower pressing part.

[0016] By adopting the above technical solution, when the upper and lower pressure parts gradually approach and squeeze the flexible water-absorbing component, the lower pressure part can better receive and collect the squeezed water. At the same time, it ensures that there is a gap when the upper and lower pressure parts rotate to the closest point, which can avoid the complete squeezing of the outer area of ​​the flexible water-absorbing component, making it easier for the water in the flexible water-absorbing component to drain. Moreover, this gap can ensure that the hinge seat, along with the absorption tube, extends between the upper and lower pressure parts.

[0017] Preferably, both the upper pressing part and the lower pressing part have gears fixed to their rotating shaft ends, the gears meshing with each other, and the second driving member is connected to the rotating shaft of the upper pressing part or the lower pressing part for transmission.

[0018] By adopting the above technical solution, when the second driving member drives the shaft of the upper or lower pressing part to rotate, the upper and lower pressing parts can be driven to rotate synchronously in a direction that moves closer to or further away from each other through the meshing transmission between gears.

[0019] Preferably, the vehicle body is equipped with a water storage tank and a sedimentation tank. The water storage tank is used for supplying water for road cleaning, and the vehicle body is equipped with a water pump for pumping water from the water storage tank to the sedimentation tank. A connecting pipe is provided between the upper ends of the water storage tank and the sedimentation tank.

[0020] By adopting the above technical solution, the water storage tank can supply water for road cleaning by sanitation vehicles. Since the water in the lower pressure section flows naturally into the water collection tank, and the position of the lower pressure section is not far from the ground, the position of the water collection tank will not be too high off the ground and the volume will not be too large. Therefore, the water in the water collection tank can be pumped to the sedimentation tank by a water pump, and after a certain sedimentation, it can flow from the connecting pipe to the water storage tank for reuse.

[0021] Preferably, the water storage tank is equipped with a filter element, and the water in the water collection tank enters the water storage tank after passing through the filter element.

[0022] By adopting the above technical solution and setting up filter components, the water entering the sedimentation tank can be filtered, thereby improving the cleanliness of the water entering the sedimentation tank and the water storage tank.

[0023] Preferably, the lower surface of the mounting portion is provided with a plurality of hinge seats at intervals, each hinge seat being spaced apart and rotatably disposed along the length direction of the mounting portion, the rotation axis of the hinge seat being disposed along the width direction of the vehicle body, the absorption roller being rotatably disposed on each of the hinge seats, and an elastic element being disposed on the hinge seat, the other end of the elastic element being connected to the mounting portion; when the hinge seat rotates, the elastic element is subjected to stretching or compression.

[0024] By adopting the above technical solution, since some parts of the ground may have protrusions when the vehicle is in motion, the flexible sponge block can undergo a certain elastic deformation when it hits the absorption roller, but it will cause a large impact on the absorption roller. However, by using the rotating hinge seat, when the absorption roller hits the protrusion, the hinge seat and the absorption roller can rotate synchronously, which further ensures that the absorption roller can pass through the ground with protrusions normally. The restoring force of the elastic element can drive the hinge seat to return to the position where the absorption roller contacts the ground.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] (1) By setting up the cooperation between the vehicle body, absorption roller, mounting part, flexible absorption component, water collection component and collection component, it is possible to absorb the water accumulated on the ground after washing, and squeeze and collect the water absorbed by the flexible water absorption component, so as to ensure the water absorption effect of the flexible water absorption component, and realize the easy cleaning and collection of some water accumulated on the ground after washing, and reduce the secondary pollution caused by water accumulation.

[0027] (2) By setting an upper pressure part, a lower pressure part and a second driving member, the flexible water-absorbing part can be squeezed and dehydrated; and by setting a groove and a water guide hole, it is convenient to temporarily collect the squeezed water.

[0028] (3) By setting the fit between the hinge seat and the elastic element, when the absorption roller touches some protrusions on the ground, it can rotate and reset, so that the absorption roller can pass through different road conditions more smoothly. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a sanitation vehicle. (Refer to...) Figure 1 and Figure 2 The sanitation vehicle includes a vehicle body 1, a water storage tank 2, an absorption roller 3, a mounting part 4, a first drive component 5, a water squeezing assembly 6, and a collection assembly 7.

[0037] The part of the vehicle body 1 closest to the front is the head, and the part of the vehicle body 1 furthest from the front is the tail. The water tank 2 is installed on the vehicle body 1 and located on the back side of the front. The water tank 2 is used to supply water to the road cleaning system.

[0038] A strip-shaped mounting plate 8 is horizontally fixed at the rear of the vehicle body 1. The mounting part 4 is also rectangular strip-shaped and is horizontally arranged along the width direction of the vehicle body 1. One long side of the mounting part 4 is rotatably connected to the long side of the mounting plate 8. When the mounting part 4 is in a horizontal position, the mounting part 4 and the mounting plate 8 are located on the same plane. The first driving component 5 is disposed on the mounting plate 8. The first driving component 5 is a servo motor. The first driving component 5 is used to drive the mounting part 4 to rotate and adjust, so as to realize the indirect rotation control between the mounting part 4 and the rear of the vehicle body 1.

[0039] Reference Figure 1 and Figure 3 A plurality of hinge seats 9 are spaced apart on the lower surface of the mounting part 4, with each hinge seat 9 spaced apart along the length direction of the mounting part 4. Each absorbent roller 3 is rotatably connected to each hinge seat 9. In this embodiment, the number of hinge seats 9 and absorbent rollers 3 is the same, and there are four of them. The rotation axis of the absorbent roller 3 is arranged along the width direction of the vehicle body 1, and each absorbent roller 3 is on the same straight line. A flexible water-absorbing element 10 is wrapped around and detachably fixed to the outside of the absorbent roller 3. The flexible water-absorbing element 10 is in the shape of a ring and is made of water-absorbing sponge or water-absorbing fabric, which has good water absorption. When the vehicle body 1 is driving and washing the ground, the absorbent roller 3 rotates due to the friction contact between the flexible water-absorbing element 10 and the ground, and the flexible water-absorbing element 10 directly rolls in contact with the ground. Therefore, the flexible water-absorbing element 10 can absorb the water accumulated on the ground, reducing the accumulation of water on the road surface after washing and preventing secondary pollution.

[0040] Reference Figure 2 and Figure 4 The water-squeezing assembly 6 is located at the rear of the vehicle body 1. Extension plates 11 are fixed at both ends of the mounting plate 8 on the vehicle body 1. The extension plates 11 are arranged along the length of the vehicle body 1, and the two extension plates 11 are arranged opposite to each other and parallel to each other. The water-squeezing assembly 6 is located at the end of the extension plate 11 away from the vehicle body 1, and the mounting part 4 is located between the water-squeezing assembly 6 and the mounting plate 8. The water-squeezing assembly 6 is used to squeeze and dehydrate the flexible water-absorbing component 10. Since the water absorption of the flexible water-absorbing component 10 becomes worse after absorbing water, the water absorption function of the flexible water-absorbing component 10 can be maintained after squeezing.

[0041] In some embodiments, the dewatering assembly 6 includes an upper pressing part 61, a lower pressing part 62, and a second driving member 63. The ends of the upper pressing part 61 and the lower pressing part 62 are rotatably connected to the vehicle body 1. The rotation shafts of the upper pressing part 61 and the lower pressing part 62 are both located on their long sides. The upper pressing part 61 and the lower pressing part 62 are arranged vertically opposite each other and their rotating sides are close to each other. The upper pressing part 61 and the lower pressing part 62 rotate synchronously in a direction that moves closer to each other or further away from each other. The second driving member 63 is disposed on the extension plate 11 and is used to drive the upper pressing part 61 and the lower pressing part 62 to rotate synchronously. In this embodiment, the second driving member 63 is selected as a servo motor mounted on the extension plate 11. When the upper pressing part 61 and the lower pressing part 62 gradually rotate closer, a squeezing chamber is formed between the upper pressing part 61 and the lower pressing part 62, and the opposing side of the upper pressing part 61 and the lower pressing part 62 squeezes the outer side of the flexible absorbent 10.

[0042] Reference Figure 4 and Figure 5 Before the flexible absorbent 10 needs to be squeezed, the upper pressing part 61 and the lower pressing part 62 rotate in opposite directions, with the side of the upper pressing part 61 and the lower pressing part 62 away from the rotating side in an open state. At this time, the upper pressing part 61 and the lower pressing part 62 can leave the path of the absorbent roller 3 rotating with the mounting part 4, ensuring that the absorbent roller 3 can rotate normally with the mounting part 4. Then, the first driving part 5 drives the mounting part 4 to rotate upward 90 degrees, so that the mounting part 4 rotates from a horizontal state to a vertical state, and drives the absorbent roller 3 and the flexible absorbent 10 to lift off the ground. At this time, the position of the absorbent roller 3 is the position of the squeezing chamber. Finally, the second driving part 63 drives the upper pressing part 61 and the lower pressing part 62 to rotate closer to squeeze the water out of the flexible absorbent 10.

[0043] The upper pressing part 61 and the lower pressing part 62 are provided with grooves 12 on their opposite sides. The bottom of the grooves 12 is arc-shaped and is adapted to the outer side of the flexible absorbent 10. When the upper pressing part 61 and the lower pressing part 62 approach each other and squeeze water out of the flexible absorbent 10, a squeezing cavity is formed between the opposite grooves 12 on the upper pressing part 61 and the lower pressing part 62, and the absorbent roller 3 is located in the squeezing cavity when squeezing.

[0044] When the upper pressing part 61 and the lower pressing part 62 rotate to their closest positions, the upper pressing part 61 is directly above the lower pressing part 62, and there is a gap between the facing sides of the upper pressing part 61 and the lower pressing part 62. Therefore, the lower pressing part 62 can better collect the squeezed water, and this gap can ensure that the hinge seat 9, along with the absorption tube, extends between the upper pressing part 61 and the lower pressing part 62 without being affected by the hinge seat 9 during squeezing; at the same time, it can avoid the complete squeezing of the outer area of ​​the flexible water-absorbing member 10, which facilitates the drainage of water inside the flexible water-absorbing member 10.

[0045] In some embodiments, gears 13 are fixed at one end of the rotating shafts of the upper pressing part 61 and the lower pressing part 62, and the two gears 13 mesh with each other. The second driving member 63 is connected to the rotating shaft of the upper pressing part 61 or the lower pressing part 62. By driving one of the rotating shafts of the upper pressing part 61 and the lower pressing part 62 to rotate through the second driving member 63, the upper pressing part 61 and the lower pressing part 62 can be driven to rotate synchronously in the direction of approaching or moving away, so that the clamps of the upper pressing part 61 and the lower pressing part 62 away from the rotating side open or close, and the position of the clamps opened by the upper pressing part 61 and the lower pressing part 62 is sufficient to ensure that the absorption roller 3 can rotate normally to the extrusion chamber.

[0046] A collection component 7 is installed on the vehicle body 1 and is used to collect the water squeezed by the flexible water-absorbing component 10. A surrounding plate 14 is fixed to the periphery of the opposing sides of the lower pressing part 62 and the upper pressing part 61. The lower pressing part 62 and the upper pressing part 61 are hollow shells. Water guide holes 15 are provided on the opposing sides of the lower pressing part 62 and at the bottom of the groove 12. The water guide holes 15 communicate with the interior of the upper pressing part 61 or the lower pressing part 62. The collection component 7 includes a flexible pipe 71 connected to the bottom of the lower pressing part 62 and a water collection tank 72 fixed to the vehicle body 1. The water collection tank 72 is located below the mounting plate 8. The flexible pipe 71 communicates with the upper end of the water collection tank 72. The lowest point where the flexible pipe 71 connects to the lower pressing part 62 is higher than the point where the flexible pipe 71 connects to the water collection tank 72. Therefore, water in the lower pressing part 62 can flow freely to the water collection tank 72 through the flexible pipe 71.

[0047] Reference Figure 2 and Figure 5 When the flexible absorbent 10 contacts the bottom of the groove 12 and is squeezed, the water in the flexible absorbent 10 is squeezed out and enters the upper pressure part 61 or the lower pressure part 62 from the water guide hole 15. The water in the upper pressure part 61 will then fall freely from the water guide hole 15 to the lower pressure part 62. Finally, the water enters the water collection tank 72 from the lower pressure part 62 through the flexible pipe 71. The enclosure 14 can reduce the direct flow of water from the edges of the upper pressure part 61 and the lower pressure part 62 to the ground.

[0048] In some embodiments, a sedimentation tank 16 is fixed to the rear of the vehicle body 1. The sedimentation tank 16 is located on the side of the water storage tank 2 facing the rear of the vehicle body 1. The height of the upper end of the sedimentation tank 16 is close to the height of the upper end of the water storage tank 2. A water pump 17 is provided on the vehicle body 1 for pumping water from the water collection tank 72 to the sedimentation tank 16. A connecting pipe 18 is provided between the upper ends of the water storage tank 2 and the sedimentation tank 16. Since the water in the pressure section 62 flows naturally into the water collection tank 72, and the position of the pressure section 62 is not far from the ground, the water collection tank 72 is not high above the ground and its volume is not large. The water collection tank 72 cannot collect too much water. Therefore, the water in the water collection tank 72 can be pumped to the sedimentation tank 16 by the water pump 17. After a certain amount is collected and settled in the sedimentation tank 16, the water can flow through the connecting pipe 18 to the water storage tank 2 for reuse.

[0049] In some embodiments, a filter element 19 is installed on the water storage tank 2. Water in the water collection tank 72 enters the water storage tank 2 after passing through the filter element 19. In this embodiment, the filter element 19 is an activated carbon box installed on the upper end of the sedimentation tank 16.

[0050] In some embodiments, the upper end of each hinge seat 9 is rotatably connected to the lower surface of the mounting part 4. The rotation axis of the hinge seat 9 is along the width direction of the vehicle body 1. An elastic element 20 is fixed on one side of the hinge seat 9, and the other end of the elastic element 20 is connected to the lower surface of the mounting part 4. The elastic element 20 is selected as a spring or an elastic column. In this embodiment, the elastic element 20 is selected as a spring, and the elastic element 20 is connected to the side of the hinge seat 9 away from the vehicle body 1. When the hinge seat 9 rotates, the elastic element 20 is stretched or compressed.

[0051] When the vehicle body 1 is in motion, there are some raised parts on the ground. When the raised parts hit the absorbent roller 3, although the flexible sponge absorbent block can undergo a certain elastic deformation, it will cause a large impact on the absorbent roller 3. However, by rotating the hinge seat 9, when the absorbent roller 3 hits the raised part, the hinge seat 9 and the absorbent roller 3 can rotate synchronously, further ensuring that the absorbent roller 3 can pass through the ground with raised parts normally. Finally, the restoring force of the elastic element 20 can drive the hinge seat 9 to reset, so that the flexible absorbent element 10 remains in contact with the ground.

[0052] The implementation principle of a sanitation vehicle in this application embodiment is as follows: when the sanitation vehicle is slowly driving and washing the ground, the absorption roller 3 at the rear of the vehicle body 1 can rotate and drive the flexible water-absorbing component 10 to contact and absorb water from the water-filled ground. Therefore, the flexible water-absorbing component 10 can absorb the water remaining on the ground after washing, reducing the water left on the ground during washing.

[0053] After the flexible absorbent 10 has been absorbing water for a period of time, the first driving member 5 can drive the mounting part 4, the hinge seat 9 and the absorbent roller 3 to rotate upward 90 degrees synchronously, causing all the absorbent rollers 3 to lift upward and leave the ground. At this time, some debris pushed away by the absorbent rollers 3 can be left on the ground. The second driving member 63 will rotate the upper pressure part 61 and the lower pressure part 62, which are in the open position on one side, closer to each other. The bottom of the groove 12 on the upper pressure part 61 and the lower pressure part 62 will squeeze and dehydrate the outside of the flexible absorbent 10. The squeezed water flows from the upper pressure part 61 to the lower pressure part 62, and then from the lower pressure part 62 to the water collection tank 72, ensuring the water absorption function of the flexible absorbent 10 and collecting the squeezed water. This makes it easier to clean and collect the water that has accumulated on the ground after rinsing, reducing secondary pollution caused by water accumulation.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
