Description

Technical Field

[0001] This utility model relates to the field of cleaning vehicle technology, and more specifically to a circulating cleaning structure for a street cleaning vehicle. Background Technology

[0002] To create a comfortable and beautiful urban life, municipal companies provide beautification services to citizens, ranging from small tasks such as urban greening, road sweeping, and garbage collection to large-scale projects such as renovation and road construction. During the beautification, cleaning, and maintenance of roads, road cleaning trucks are needed to sweep the road surface. The cleaning method involves spraying high-speed water directly onto the ground, and using rotating brushes in conjunction with a vacuum cleaner to clean the road surface. The purpose of spraying high-speed water during the cleaning process is to soften stubborn stains and reduce dust during cleaning. However, during use, the high-speed water spray can easily cause water splashing, and too much water remains on the ground, which can lead to water waste. Therefore, there is an urgent need to design a circulating cleaning structure for street cleaning trucks. Utility Model Content

[0003] To overcome the aforementioned deficiencies in the prior art, this utility model provides a circulating cleaning structure for a street cleaning vehicle. This addresses the problem in the background art where, during road beautification, cleaning, and maintenance, a road cleaning vehicle is needed to sweep the road surface. The sweeping method involves directly spraying high-speed water onto the ground, and using rotating brushes in conjunction with a vacuum cleaner to clean the road surface. While the purpose of spraying high-speed water during cleaning is to soften stubborn stains and reduce dust, the high-speed water spray can easily cause splashing and excessive water residue, leading to water waste.

[0004] This utility model provides the following technical solution: a circulating cleaning structure for a street cleaning vehicle, comprising a device body, the device body including a cleaning vehicle body and a frame body, a water spraying assembly installed on one side of the bottom of the frame body via a connecting component, the water spraying assembly including a water storage tank, the water storage tank being located at the bottom of the frame body, a water pump fixedly installed on the outside of the water storage tank, a water suction pipe fixedly installed at the water inlet end of the water pump, the water suction pipe extending through into the interior of the water storage tank, a water outlet pipe fixedly installed at the water outlet end of the water pump, a first T-connector pipe connected to the bottom end of the water outlet pipe, a first corrugated pipe connected to both ends of the first T-connector pipe, a water injection pipe connected to the top of the water storage tank, a plug threaded on the outside of the water injection pipe, a self-priming centrifugal pump fixedly installed at the top of the water storage tank, and a discharge end of the self-priming centrifugal pump... A liquid outlet pipe is fixedly installed, extending through the interior of the water storage tank. An inlet pipe is fixedly installed at the suction end of the self-priming centrifugal pump. A second three-way pipe is connected to the end of the inlet pipe furthest from the self-priming centrifugal pump. Second corrugated pipes are connected to both ends of the second three-way pipe, located in front of the first three-way pipe. An exhaust pipe is connected to the top of the water storage tank. Agitators are installed at the bottom of each of the second corrugated pipes. During the movement of the cleaning vehicle, the pump operates, causing a high-speed water jet to spray from the bottom of the first corrugated pipe. The splashed water is drawn into the self-priming centrifugal pump by the pump's operation, mixing water with air. The liquid then enters the water storage tank through the liquid outlet pipe for recycling. This design allows water splashed into the air during ground spraying to be collected and recycled back into the water storage tank.

[0005] Furthermore, a filter screen is installed inside the water storage tank, and the end of the liquid outlet pipe away from the self-priming centrifugal pump is located at the top of the filter screen plate, which can filter the liquid recovered by the liquid outlet pipe.

[0006] Furthermore, an inspection port is provided through the outer side of the water storage tank, and a lockable door is hinged to the outer side of the water storage tank. The door is located outside the inspection port. The filter screen is inclined. After opening the support rod, the dust and other debris on the top of the filter screen can be cleaned through the inspection port.

[0007] Furthermore, the exhaust pipe is spring-shaped, allowing gas inside the water tank to escape through it. The spring-shaped exhaust pipe prevents liquid inside the water tank from overflowing through the exhaust pipe when walking.

[0008] Furthermore, a first motor is fixedly installed on the outside of the water storage tank. A double-ended lead screw is fixedly installed at the output end of the first motor. A movable frame is threaded onto the outer sides of both ends of the double-ended lead screw. A connecting rod is fixedly installed on the outer side of each movable frame. A first collar is fixedly installed on the end of each connecting rod away from the movable frame. The first collar is sleeved on the outside of the first corrugated pipe. A connecting frame is fixedly installed on the outer side of each first corrugated pipe. A second collar is fixedly installed on the end of each connecting frame away from the first corrugated pipe. The second collar is sleeved on the outside of the second corrugated pipe, which allows adjustment of the distance between the first and second corrugated pipes.

[0009] Furthermore, the connecting assembly includes two connecting seats, which are located on both sides of the top of the water tank. The connecting seats are connected to the vehicle frame body by bolts. Each connecting seat has a support column fixedly installed at its bottom end. The bottom end of each support column is open. A support rod is slidably installed at the bottom end of each support column. The bottom end of each support rod is fixedly connected to the top of the water tank. A through hole is opened on the outer side of each support column. Threaded grooves are opened at equal intervals on the front side of each support rod to facilitate the connection between the water tank and the cleaning vehicle body. After connection, the distance between the water tank and the ground can be adjusted for adaptability.

[0010] Furthermore, a groove is provided through the outer side of the support column, and a slider is slidably installed inside the groove. The slider is fixedly connected to the support rod. During the up-and-down movement of the support rod, the slider slides downward inside the groove, which can prevent the support rod and the support column from separating.

[0011] Furthermore, an opening is provided through the outer side of the tank door, and an observation window is embedded in the opening on the front side of the tank door to facilitate observation of the liquid level inside the water storage tank.

[0012] Furthermore, the agitation assembly includes a connecting pipe, which is fixedly installed at the bottom end of the second corrugated pipe. A bracket is fixedly installed on the outside of the connecting pipe, and a second motor is fixedly installed at the bottom end of the bracket. A gear is fixedly installed on the outside of the output end of the second motor. A sleeve ring is rotatably installed on the outside of the connecting pipe via a bearing. An external gear ring is fixedly installed on the outside of the sleeve ring, and the external gear ring meshes with the gear. A connecting ring is provided at the bottom end of the sleeve ring, and the connecting ring is sleeved on the outside of the connecting pipe. Hard brush strips are equidistantly installed on the outside of the connecting ring. When the second motor operates, the connecting ring rotates. By rotating and adhering to the ground through the brush strips outside the connecting ring, the ground can be cleaned. Furthermore, the brush strips on the connecting ring can agitate water on the ground into the air, increasing the capacity of the recovered liquid.

[0013] Furthermore, the connecting ring and the sleeve ring are detachably connected by a flange, which facilitates disassembly and replacement.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model, by incorporating a water spray component, achieves a high-speed water flow by operating the water pump during the movement of the cleaning vehicle body. The splashed water source is drawn into the self-priming centrifugal pump by the operation of the self-priming centrifugal pump, and the liquid enters the water storage tank through the liquid outlet pipe for recycling. With this design, water splashed into the air can be collected and recycled into the water storage tank during the water spraying process on the ground.

[0016] 2. This utility model incorporates an agitation component. This design allows the second motor to rotate during the cleaning process of the device body. Due to the meshing between the gear and the external gear ring, the connecting ring rotates outside the connecting pipe, thereby causing the brush strips outside the connecting ring to rotate and adhere to the ground. The brush strips on the connecting ring can agitate the water on the ground, causing excess water to float in the air. This water then mixes with air and enters the second corrugated pipe for recycling.

[0017] 3. This utility model, by providing a connecting component, adopts a design that connects the connecting seat and the bottom of the vehicle frame body by bolts passing through the connecting seat. By rotating and removing the screws that pass through the through hole and the threaded groove, the water tank body can be adjusted up and down. After adjustment, the screws are locked after passing through the through hole and the threaded groove. With this design, the distance between the water spray component and the vehicle frame body can be adjusted during installation, thereby adjusting the height between the first corrugated pipe, the second corrugated pipe and the ground.

A water outlet pipe 213 is fixedly installed at the water outlet end of the water pump 211, and a first three-way pipe is connected to the bottom end of the water outlet pipe 213. 214, the other two ends of the first three-way pipe 214 are connected to and installed with a first corrugated pipe 215. The top of the water storage tank 210 is connected to and installed with a water injection pipe 228. A plug 229 is threaded on the outside of the water injection pipe 228. A self-priming centrifugal pump 221 is fixedly installed at the top of the water storage tank 210. A liquid outlet pipe 222 is fixedly installed at the discharge end of the self-priming centrifugal pump 221. The liquid outlet pipe 222 extends through into the interior of the water storage tank 210. A liquid inlet pipe 223 is fixedly installed at the suction end of the self-priming centrifugal pump 221. The end of the liquid inlet pipe 223 away from the self-priming centrifugal pump 221 is connected to and installed with a second three-way pipe 224. The other two ends of the second three-way pipe 224 are connected to and installed with a second corrugated pipe 225. 225 is located in front of the first three-way pipe 214. An exhaust pipe 233 is connected to the top of the water storage tank 210. Agitators 400 are provided at the bottom of the second corrugated pipe 225. A filter screen 232 is installed inside the water storage tank 210. The end of the outlet pipe 222 away from the self-priming centrifugal pump 221 is located at the top of the filter screen 232. An inspection port 230 is provided through the outside of the water storage tank 210. A lockable door 231 is hinged to the outside of the water storage tank 210. The door 231 is located outside the inspection port 230. The filter screen 232 is inclined. The exhaust pipe 233 is spring-shaped. A first motor 216 is fixedly installed on the outside of the water storage tank 210. A double-ended lead screw 217 is fixedly installed at the output end of the 6. A movable frame 218 is threadedly installed on the outer side of both ends of the double-ended lead screw 217. A connecting rod 219 is fixedly installed on the outer side of the movable frame 218. A first collar 220 is fixedly installed on the end of the connecting rod 219 away from the movable frame 218. The first collar 220 is sleeved on the outside of the first bellows 215. A connecting frame 226 is fixedly installed on the outer side of the first bellows 215. A second collar 227 is fixedly installed on the end of the connecting frame 226 away from the first bellows 215. The second collar 227 is sleeved on the outside of the second bellows 225.

[0028] The working principle of Embodiment 1 of this utility model is as follows: During use, water is injected into the water storage tank 210 through the water injection pipe 228 by rotating the plug 229. While the device body 100 is moving, the water pump 211 pumps the water from the water storage tank 210 to the first three-way pipe 214 through the water extraction pipe 212, and then sprays it onto the ground through the first corrugated pipe 215. During this process, the operation of the self-priming centrifugal pump 221 creates a negative pressure at the bottom of the second corrugated pipe 225, allowing the splashed water to mix with air and be drawn into the self-priming centrifugal pump 221 through the second three-way pipe 224 and the liquid inlet pipe 223. The self-priming centrifugal pump 221 separates the gas and liquid, and the liquid is returned to the water storage tank 210 through the liquid outlet pipe 222. Inside, the liquid passes through the filter screen 232 and falls back into the water storage tank 210 for recycling. The filter screen 232 can filter dust and impurities in the liquid. After the device body 100 is used, the door 231 can be opened and the surface of the filter screen 232 can be cleaned through the inspection port 230. During use, the first motor 216 causes the double-headed screw 217 to rotate. At this time, the moving frame 218 moves closer or further away from each other outside the double-headed screw 217, thereby adjusting the distance between the first bellows 215 and the second bellows 225. During the movement of the moving frame 218, the characteristics of the first bellows 215 and the second bellows 225 can be deformed and adapted accordingly.

[0029] Example 2:

[0030] The difference between Embodiment 2 and Embodiment 1 is that: the connecting assembly 300 includes two connecting seats 310, which are located on both sides of the top of the water tank 210. The connecting seats 310 and the frame body 111 are connected by bolts. A support column 311 is fixedly installed at the bottom of each connecting seat 310. The bottom of each support column 311 is open. A support rod 312 is slidably installed at the bottom of each support column 311. The bottom of each support rod 312 is fixedly connected to the top of the water tank 210. A through hole 314 is provided on the outer side of the support column 311. Threaded grooves 31 are provided at equal intervals on the front side of the support rod 312. 3. A groove 315 is provided through the outer side of the support column 311. A slider 316 is slidably installed inside the groove 315. The slider 316 and the support rod 312 are fixedly connected. The agitator assembly 400 includes a connecting pipe 410, which is fixedly installed at the bottom end of the second corrugated pipe 225. A bracket 411 is fixedly installed on the outer side of the connecting pipe 410. A second motor 412 is fixedly installed at the bottom end of the bracket 411. A gear 413 is fixedly installed on the outer side of the output end of the second motor 412. A sleeve ring 414 is rotatably installed on the outer side of the connecting pipe 410 through a bearing. An external gear ring 415 is fixedly installed on the outer side of the sleeve ring 414. The external gear ring 415 and the gear... The wheels 413 mesh with each other, and the bottom end of the sleeve ring 414 is provided with a connecting ring 416. The connecting ring 416 is sleeved on the outside of the connecting pipe 410. Hard brush strips are installed at equal intervals on the outer side of the connecting ring 416. The connecting ring 416 and the sleeve ring 414 are detachably connected by a flange. The connecting seat 310 is connected to the bottom of the frame body 111 by bolts passing through the connecting seat 310. The screws passing through the through hole 314 and the threaded groove 313 are removed by rotating, and the water tank 210 is adjusted up and down. After the adjustment is completed, the screws are locked after passing through the through hole 314 and the threaded groove 313. With this design, the water spray assembly 200 and the connecting ring 416 can be adjusted during installation. The distance between the main body 111 of the frame is adjusted to adjust the height between the first corrugated pipe 215, the second corrugated pipe 225 and the ground. During the cleaning process of the device body 100, the second motor 412 rotates. Due to the meshing between the gear 413 and the external gear ring 415, the sleeve ring 414 rotates outside the connecting pipe 410, which in turn drives the brush strip outside the connecting ring 416 to rotate and adhere to the ground. The brush strip on the connecting ring 416 can cause the water on the ground to agitate, which can agitate the excess water on the ground to float in the air, thereby mixing with the air and entering the second corrugated pipe 225 through the connecting pipe 410 for recycling.
