In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their description will be omitted.

[0037] Combined with Figures 1 to 4 As shown, according to a specific embodiment of the present application, a sanitation vehicle is provided.

[0038] Specifically, the sanitation vehicle includes a tank body 10 and a pipeline system. The tank body 10 is connected to the chassis 20. A part of the pipeline system is connected to the chassis 20. The pipeline system includes an operation pipeline 30 and a circulation pipeline. The circulation pipeline includes a liquid inlet pipeline 41, a liquid outlet pipeline 42 and a driving part 43. The first end of the liquid inlet pipeline 41 is communicated with the tank body 10. The second end of the liquid inlet pipeline 41 is communicated with the operation pipeline 30. The first end of the liquid outlet pipeline 42 is communicated with the operation pipeline 30. The second end of the liquid outlet pipeline 42 is communicated with the tank body 10. The driving part 43 is located on the liquid inlet pipeline 41. Wherein, the driving part 43 drives the liquid in the tank body 10 to circulate through the liquid inlet pipeline 41, the liquid outlet pipeline 42 and the operation pipeline 30 for a preset time, and then drives the circulated liquid to be discharged through the operation pipeline 30 for operation.

[0039] Applying the technical solution of the present invention, the liquid in the tank body 10 is driven to circulate through the circulation pipeline by the driving part 43, so that the concentration of the liquid in the tank body 10 is uniform, reducing the corrosion ability of the liquid to the inner wall of the pipeline. Then, the driving part 43 drives the liquid to perform operations through the operation pipeline 30, effectively protecting the pipelines of the sanitation vehicle and extending the service life of the sanitation vehicle. Adopting the technical solution of this application, the structure of the sanitation vehicle is simple and reliable, solving the problem that the pipelines of the sanitation vehicle in the prior art are not corrosion-resistant.

[0040] As Figure 1 shown, the liquid inlet pipeline 41 includes a first pipe section 411 and a second pipe section 412. The first end of the first pipe section 411 is communicated with the tank body 10. The second end of the first pipe section 411 is communicated with the water inlet of the driving part 43. The first end of the second pipe section 412 is communicated with the water outlet of the driving part 43. The second end of the second pipe section 412 is communicated with the operation pipeline 30. Such a setting enables the liquid entering from the liquid inlet pipeline 41 to return to the tank body 10 after being pressurized by the driving part 43, thereby promoting the continuous dissolution of the medium and making the concentration of the liquid in the tank body 10 more uniform.

[0041] Furthermore, the operation pipeline 30 includes a third pipe section 35. The first end of the third pipe section 35 is communicated with the second end of the second pipe section 412. Such a setting extends the path of the liquid circulating through the circulation system, making the mixing of the solvent and the medium more uniform.

[0042] As Figure 1 shown, the liquid outlet pipeline 42 includes a fourth pipe section 422. The first end of the fourth pipe section 422 is communicated with the second end of the third pipe section 35. The second end of the fourth pipe section 422 extends upward into the tank body 10. The fourth pipe section 422 has a first valve. Such a setting enables the liquid pressurized by the driving part 43 to return to the tank body 10, and the closing of the circulation pipeline is controlled by the first valve, further improving the practicability of the sanitation vehicle.

[0043] The operation pipeline 30 further includes a fifth pipe section 31 and a sixth pipe section 32. The first end of the fifth pipe section 31 is communicated with the first end of the third pipe section 35. The first end of the sixth pipe section 32 is communicated with the second end of the fifth pipe section 31. The second end of the sixth pipe section 32 has a first spraying device 321. The second end of the sixth pipe section 32 has a second valve. Such a setting enables the liquid after circulation to be discharged along the sixth pipe section 32 for operation. Among them, the first spraying device 321 can be set as a handheld type or fixed at the rear end of the chassis 20. The fifth pipe section 31 can be integrally formed with the third pipe section 35.

[0044] As Figure 1 and Figure 2As shown in the figure, the operation pipeline 30 further includes a seventh pipe section 33 and an eighth pipe section 34. The first end of the seventh pipe section 33 communicates with the second end of the fifth pipe section 31. The middle part of the eighth pipe section 34 communicates with the second end of the seventh pipe section 33. A first nozzle 341 and a third valve are provided at the first end of the eighth pipe section 34. A second nozzle 342 and a fourth valve are provided at the second end of the eighth pipe section 34. Such a setting enables the liquid after circulation to be discharged along the pipelines at both ends of the eighth pipe section 34 for operation, increasing the operation range of the sanitation vehicle.

[0045] Furthermore, the pipeline system further includes an anti-overflow pipeline, which includes a collection tank 51, an anti-backflow device 52, and a water-blocking elbow 53. The collection tank 51 is installed on the chassis 20. The anti-backflow device 52 is fixedly connected to the tank body 10. The first end of the water-blocking elbow 53 communicates with the anti-backflow device 52. The second end of the water-blocking elbow 53 communicates with the collection tank 51. Such a setting enables part of the liquid entering from the anti-backflow device 52 to be blocked by the water-blocking elbow 53 and temporarily stored in the anti-backflow device 52, and a small amount of liquid that crosses the water-blocking elbow 53 will also be stored in the collection tank 51, effectively preventing the liquid in the tank body 10 from overflowing outside the tank body 10.

[0046] As Figure 1 shown, the anti-backflow device 52 includes an anti-backflow elbow 521 and a ninth pipe section 522. The first end of the anti-backflow elbow 521 is arranged towards the top of the tank body 10. The first end of the ninth pipe section 522 communicates with the second end of the anti-backflow elbow 521. The second end of the ninth pipe section 522 communicates with the first end of the water-blocking elbow 53. Such a setting enables part of the liquid about to overflow in the tank body 10 to enter the ninth pipe section 522 from the anti-backflow elbow 521 for temporary storage. Among them, when the sanitation vehicle is braking, part of the liquid temporarily stored in the ninth pipe section 522 will return to the tank body 10 under the action of inertia.

[0047] Specifically, the pipeline system further includes an anti-freezing pipeline 60. The first end of the anti-freezing pipeline 60 communicates with the ninth pipe section 522, and the second end of the anti-freezing pipeline 60 communicates with the collection tank 51. The anti-freezing pipeline 60 also has a fifth valve 61. Such a setting enables the artificial discharge of the liquid temporarily stored in the ninth pipe section 522, and the temporarily stored liquid will not freeze due to too low external temperature, thus effectively preventing the normal use of the sanitation vehicle from being affected by the external low-temperature environment.

[0048] As Figure 1As shown, the sanitation vehicle further includes a liquid discharge pipeline 70. The first end of the liquid discharge pipeline 70 is communicated with the tank body 10. The first end of the liquid discharge pipeline 70 is provided with a sixth valve 71. The second end of the liquid discharge pipeline 70 is provided with a seventh valve 72. The seventh valve 72 is used to connect docking devices of different models. Such a setting enables the sanitation vehicle to select docking devices of different models according to different working environments when discharging the liquid in the tank body 10, increasing the applicable occasions of the sanitation vehicle and improving the practicability of the sanitation vehicle.

[0049] As Figure 3 shown, the collection box 51 further includes a collection box body 511, a detection device, and a tenth pipe section 515. The collection box body 511 is connected to the chassis 20. The detection device is arranged on the collection box body 511. The detection device includes a liquid level gauge 512, a liquid level sensor 513, and a ventilation device 514. The first end of the tenth pipe section 515 is communicated with the collection box body 511. The second end of the tenth pipe section 515 is communicated with the liquid discharge pipeline 70, and the tenth pipe section 515 is provided with an eighth valve 516. Such a setting enables the ventilation device 514 to balance the pressure in the collection box 51. At the same time, the liquid level gauge 512 and the liquid level sensor 513 can monitor and record the liquid level height of the collection box 51. When the liquid level height of the collection box 51 is about to approach the preset maximum height, the staff can be reminded to perform liquid discharge treatment on the collection box 51.

[0050] In order to further improve the corrosion resistance of the pipeline of the sanitation vehicle, the pipeline of the sanitation vehicle is made of metal materials or engineering plastics. Among them, the metal material can be 304 stainless steel, and the engineering plastic can be PE plastic.

[0051] As Figure 4 shown, the anti-backflow elbow 521 includes an eleventh pipe section 5211 and a twelfth pipe section 5212. The eleventh pipe section 5211 is arranged vertically. The eleventh pipe section 5211 is arranged towards the top of the tank body 10. The twelfth pipe section 5212 is an arc-shaped pipe. The first end of the twelfth pipe section 5212 is communicated with the second end of the eleventh pipe section 5211. The twelfth pipe section 5212 is located below the eleventh pipe section 5211. The height of the first end of the twelfth pipe section 5212 in the vertical direction is greater than the height of the second end of the twelfth pipe section 5212 in the vertical direction. Such a setting can prevent the liquid in the tank body 10 from overflowing and a large amount of liquid from flowing back into the anti-backflow elbow 521 to the greatest extent.

[0052] The water-blocking elbow 53 includes a thirteenth pipe section 531, a fourteenth pipe section 532, and a fifteenth pipe section 533. The first end of the thirteenth pipe section 531 communicates with the second end of the ninth pipe section 522. The thirteenth pipe section 531 is an arc-shaped pipe. The second end of the thirteenth pipe section 531 extends toward the top side of the tank body 10. The first end of the fourteenth pipe section 532 communicates with the second end of the thirteenth pipe section 531. The fourteenth pipe section 532 is a U-shaped pipe. The middle part of the fourteenth pipe section 532 is bent toward the top side of the tank body 10. The first end of the fifteenth pipe section 533 communicates with the second end of the fourteenth pipe section 532, and the second end of the fifteenth pipe section 533 is arranged toward the bottom side of the tank body 10 and communicates with the collection box 51. Such a setting makes the structure of the water-blocking elbow 53 simple, and at the same time, not all the liquid entering the ninth pipe section 522 will enter the collection box 51, playing a role in preventing the liquid from flowing back into the collection box 51.

[0053] According to another embodiment of the present application, the sanitation vehicle utilizes the principle that the liquid levels in the connected pipelines always remain at the same horizontal plane when the liquid is not flowing, effectively preventing the liquid in the tank body 10 of the sanitation vehicle from spilling. At the same time, the sanitation vehicle is provided with a circulation system, so that complex media such as disinfectant and snow melting agent in the tank body 10 can be fully dissolved with the solvent in the tank body 10, preventing the complex media with a relatively high concentration still existing in the tank body 10 or the pipeline from damaging the pipeline. The sanitation vehicle is also equipped with a collection box 51, an operation pipeline 30, an anti-freezing pipeline 60, and a multi-connected liquid discharge pipeline, which can realize operations such as spraying, disinfection, and transportation.

[0054] Specifically, an anti-overflow pipeline is installed inside the tank body 10 of the sanitation vehicle. Fixing brackets for the anti-overflow pipeline can be provided to fix part of the anti-overflow pipeline inside the tank body 10. At the same time, a plurality of anti-wave plates can be arranged in parallel inside the tank body 10. The anti-wave plates play a role in reducing the sloshing of the liquid inside the tank body 10 and supporting the anti-overflow pipeline. By providing an anti-backflow device 52 at the front end of the anti-overflow pipeline, it effectively prevents a large amount of liquid from pouring into the ninth pipe section 522 when the sanitation vehicle is moving forward and braking. Similarly, a water-blocking elbow 53 is provided at the rear end of the anti-overflow pipeline, so that a small amount of liquid that enters the anti-backflow elbow 521 when the sanitation vehicle starts or brakes can be stored in the ninth pipe section 522 and will not flow backward into the collection tank 51. The collection tank 51 is arranged behind the chassis 20 of the sanitation vehicle. When the sanitation vehicle is driving on a slope with an angle higher than a certain degree, a small amount of liquid temporarily stored in the ninth pipe section 522 will cross the water-blocking elbow 53 and enter the collection tank 51. A liquid level gauge 512, a liquid level sensor 513, and a ventilation device 514 are provided on the collection tank 51. The ventilation device 514 can adjust the air pressure balance inside the tank body 10, and the liquid level gauge 512 can timely monitor the liquid level height on the collection tank 51. When the sanitation vehicle discharges the liquid inside the tank body 10, the sixth valve 71 is closed, and at the same time, the eighth valve 516 is opened. The liquid inside the collection tank 51 enters the liquid discharge pipeline 70 and flows out through the seventh valve 72.

[0055] Furthermore, when the sanitation vehicle is driving on an uphill section, the height of the pipe orifice of the eleventh pipe section 5211 is higher than the liquid level inside the tank body 10, which plays a role in preventing the liquid inside the tank body 10 from flowing back into the anti-backflow elbow 521. When the sanitation vehicle is driving on a downhill section, a small amount of liquid will pour into the anti-backflow elbow 521, but due to the limited space inside the ninth pipe section 522, the liquid level height inside the ninth pipe section 522 will not exceed the height of the water-blocking elbow 53, which also plays a role in preventing liquid overflow and backflow. When the sanitation vehicle is in a starting state, a small amount of liquid inside the ninth pipe section 522 will enter the collection tank 51 under the influence of inertia and be stored, which also plays a role in preventing overflow.

[0056] When the sanitation vehicle is in a low-temperature environment, the residual liquid inside the ninth pipe section 522 can flow into the collection tank 51 by opening the fifth valve 61, preventing the liquid inside the pipeline from freezing and affecting the normal use of the sanitation vehicle. When the sanitation vehicle needs to continuously dissolve or stir complex media, opening the drive part 43 and the first valve can perform dissolution and stirring operations through the circulation pipeline. And when the first valve is closed, the complex liquid inside the tank body 10 can be sprayed, atomized, irrigated, disinfected, snow-melted, etc. through the operation pipeline 30.

[0057] In this application, the sanitation vehicle can achieve multiple complex operations through a variety of connecting pipelines, effectively solving the problems of liquid spillage and frequent pipeline damage during the transportation, spraying, irrigation, etc. of complex liquids or corrosive liquids in the existing sanitation vehicle pipelines, improving the service life of the sanitation vehicle, and saving unnecessary labor time and labor costs.

[0058] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures.
