Description

Technical Field

[0001] The invention belongs to the technical field of traffic environmental protection, and specifically relates to a road cleaning device and a use method thereof. Background Art

[0003] The traditional greening tool, the sprinkler truck, is widely used on urban roads. Although it can reduce environmental pollution to a certain extent, it still has some defects: First, the sprinkler truck uses fossil fuels as a power source, and its combustion produces a large amount of greenhouse gases such as carbon dioxide, which will also have a negative impact on the environment. Secondly, the sprinkler truck uses a single spraying method, the water mist particles are large, and the spraying range is relatively small. During the spraying process, it is easy to splash pedestrians and cause a waste of water resources. Finally, the labor cost required for the sprinkler truck is too high.

[0004] Therefore, in order to solve the above-mentioned problems, a road cleaning device and a method of use are provided, which can replace the spraying trucks on urban roads and reduce carbon emissions. Summary of the invention

[0005] The purpose of the invention is to solve the technical defects of the existing spraying vehicles.

[0006] The technical solution for achieving the purpose of the present invention is:

[0007] A road cleaning device and a use method thereof include a mist spray head, a water flow purifier, a water pipe, a water storage tank, a timer, an electromagnetic control valve, a water pump, a sewer, a green belt, and a curbstone.

[0008] The above-mentioned road cleaning device and use method, the size of the mist spray head is set according to the area of ​​the curb, occupying approximately two-thirds of the surface of the curb. According to the common curb specifications, it can be set as follows: when the curb surface is 100cm×30cm, the spray head size is 80cm×15cm, when the curb surface is 50cm×30cm, the spray head size is 30cm×15cm, and so on. Its installation position is centrally embedded in the curb. The spray head spray mask has a porous structure, and the spray head is installed parallel to the ground. It can produce fine water mist particles when spraying, so that the sprayed water flow can be evenly sprayed on the road. This installation method can achieve a large coverage effect, and can also reduce water resource waste, reduce dust and reduce carbon emissions.

[0009] The aforementioned road cleaning device and method of use, the water purifier contains an activated carbon filter element and a small amount of 84 disinfectant. The activated carbon filter element in the purification substance can be used to remove impurities and particulate matter in the water flow, and the 84 disinfectant can eliminate harmful bacteria in the water to a certain extent, minimizing damage to vehicles and pedestrians.

[0010] In the aforementioned road cleaning device and method of use, a flow meter is installed inside the water pipe at the front interface of the water storage tank. The presence of the flow meter can control the water flow rate to ensure that the same amount of water is sprayed each time.

[0011] The aforementioned road cleaning device and method of use, the water storage tank is shaped as an elliptical cylinder with a capacity of 5L. Since the plastic water storage tank is simple and flexible and can be formed in one step, in the present invention, the water storage tank is made of linear low-density polyethylene, which has the advantages of being odorless, non-toxic, light in weight, and heat-resistant, thereby reducing the project cost.

[0012] The aforementioned road cleaning device and method of use, wherein a water pump is provided between the water storage tank and the sewer for extracting sewage from the city sewer.

[0013] In the aforementioned road cleaning device and method of use, an electromagnetic control valve is provided outside the water pump outlet to control the flow of water and realize a timed spraying function.

[0014] In the above-mentioned road cleaning device and method of use, a timer is arranged above the electromagnetic control valve, and the switch of the electromagnetic control valve is controlled by a set time interval, thereby controlling the spraying time and frequency.

[0015] The aforementioned road cleaning device and method of use, the water purifier is composed of a water inlet, a gravel filter, a filter, activated carbon, a disinfectant injection port, a reaction tank and a water outlet. Before the activated carbon layer, a gravel filter is set to remove larger particles in the water to protect the activated carbon from being saturated too quickly; the 84 disinfectant delivery device is provided with an independent disinfectant storage container, which cooperates with a micro pump or an injection pump to accurately inject an appropriate amount of 84 disinfectant into the water flow. The device can automatically adjust the amount of disinfectant added according to the water flow to achieve the best disinfection effect.

[0016] In the aforementioned road cleaning device and method of use, the water purifier reaction tank is a mixing zone: the disinfectant input point is set after the water flow and the activated carbon to form a mixing zone, ensuring that the disinfectant can be fully mixed with the water flow and exert a disinfection effect.

[0017] The above-mentioned road cleaning device and method of use, the overall process of the water purifier is: the sewage is first preliminarily filtered through sand and gravel to remove larger particles; the filtered water flows into the activated carbon layer for physical and chemical purification; after activated carbon purification, the water flow and the injected 84 disinfectant are fully mixed and reacted in the reaction tank; finally, the reacted water flows out of the water filter to ensure that the clean and disinfected water flow is sprayed in a mist through the spray head.

[0018] The road cleaning device and the use method provided by the present invention have the following advantages compared with the traditional sprinkler truck:

[0019] 1. The road cleaning device and the method of use provided by the present invention replace part of the traditional sprinkler trucks, reducing the emission of greenhouse gases such as carbon dioxide.

[0020] 2. The road cleaning device and use method provided by the present invention adopts spraying technology, and the sprayed water mist particles are small and cover a large area, thereby reducing the waste of water resources.

[0021] 3. The road cleaning device and the method of use provided by the present invention are installed on the curbstone of the green belt, avoiding the need for new paving equipment, greatly reducing the floor space, and lowering the construction cost. In addition, it is installed parallel to the ground so that the spraying height is not high, which can prevent water from being sprayed onto the windshield of a motor vehicle during driving, affecting the driver's line of sight and reducing driving safety hazards.

[0022] 4. The water source of the road cleaning device and the method of use provided by the present invention is purified to ensure that the sprayed water mist is of good quality and reduces pollution to the environment.

[0023] 5. The road cleaning device and the method of use provided by the present invention are installed in parallel on both sides of the motor vehicle lane to avoid spraying pedestrians. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example

[0038] When the size of a single curb 91 of the urban road green belt is 100cm×30cm, according to the above introduction, a mist spray head 1 with a size of 80cm×15cm is selected to be embedded in the center of the curb 91 and installed parallel to the ground. The interval between the two mist spray heads 1 is set to 3m. When the spray heads 1 are arranged on the green belts 9 on both sides of the motor vehicle lane 12, relative balance and coordination are ensured. When the mist spray heads 1 on both sides are arranged, they are cross-installed on the curb 91. The water pump 7 is driven by a motor. When the water pump 7 is started, negative pressure is created to draw sewage from the sewer 8 and transport it to the water storage tank 4, and then it is pushed to the spray head 1 by the water pipe 3 through the water source purifier 2. The electromagnetic The control valve 6 consists of an electromagnetic coil and a valve body. When the electromagnetic coil is energized, the electromagnetic force generated will cause the valve body to open or close, thereby controlling the flow of water source 7 in the water pump. The timer 5 includes a clock circuit and a timing circuit, which triggers the switch action according to the set time parameters. The spraying is set to be performed once every 30 minutes.
