Description

A sewage recovery device for a road cleaning vehicle and a guardrail cleaning vehicle

technical field

The utility model relates to sewage recovery of cleaning vehicles, in particular to a sewage recovery device for road cleaning vehicles and a guardrail cleaning vehicle.

Background technique

The guardrail cleaning vehicle is a kind of road cleaning vehicle used to clean the guardrail of urban highways. The guardrail cleaning vehicles on the market mainly clamp the guardrail through pairs of roller brushes, and use several fan-shaped nozzles installed on high and low pressure waterways to spray the roller brushes. Water is sprayed, and at the same time, the driving device drives each pair of rolling brushes to rotate, and the bristles installed on the rolling brushes are used to clean the guardrails on urban roads. However, during the guardrail cleaning process, the roller brush needs to be sprayed with water, and the water flow will flow to the road on both sides of the guardrail at the root of the guardrail with dirt, debris and the like on the guardrail, causing secondary pollution on the road.

In order to solve the above-mentioned technical problems, the Chinese patent application whose publication number is CN106284138A discloses a guardrail cleaning vehicle containing a purification device. Tank 103, the interior of water storage tank 103 is divided into clean water tank 104 and sewage tank 105, is provided with filtering device 106 between clean water tank 104 and sewage tank 105, and the top of water storage tank 103 is provided with liquid inlet 107, and liquid inlet 107 communicates with the clean water tank 104, the water storage tank 103 is provided with a support frame 108, the support frame 108 is provided with a connecting rod 109, the connecting rod 109 is provided with a liquid outlet, and the inside is provided with a passage, and the connecting rod 109 is connected to the clean water tank 109. The water tanks 104 are connected, the two sides of the connecting rod 109 are bent downwards, and both ends are provided with a vertical roller brush 110, the lower end of the roller brush 110 is provided with a water tank 111, and one side of the water tank 111 is provided with an infusion tube 112 , the infusion pipe 112 is provided with a water pump 113, and the infusion pipe communicates with the sewage tank 105. The bottom of the water receiving tank 111 is inclined, and the side of the water receiving tank 111 close to the infusion tube 112 is relatively low in level. When in use, the cleaning liquid in the clean water tank 104 flows out from the liquid outlet on the connecting rod 109, and flows onto the roller brush 110, and the roller brush 110 cleans the guardrail under the action of the cleaning liquid, and then the used cleaning The liquid drop falls in the water receiving tank 111. Since the bottom of the water receiving tank 111 is inclined, the cleaning liquid flows to a lower place and all flows into the infusion pipe 112, and the cleaning liquid is transported to the sewage tank 105 by the action of the water pump 113. Then the cleaning liquid is filtered through the filtering device 106 and finally flows into the water purification tank again.

The above-mentioned cleaning vehicle can recycle the used cleaning solution and reuse it, thus greatly prolonging the cleaning distance of the cleaning vehicle and greatly reducing the waste of cleaning solution. However, during the rotation of the roller brush, the water droplets on it will be thrown out, which will still cause sewage to flow onto the road surface, and the water receiving tank needs to avoid interference with the guardrail during work. The water receiving tank cannot be very close to the guardrail. The distance between the guardrails needs to be greater than the distance between the roller brush and the guardrail, so that part of the water on the roller brush cannot fall into the water receiving tank, and the sewage recovery effect is not ideal.

The Chinese patent application publication number CN 103696388 A discloses a sewage filtration system and a cleaning vehicle, which is provided with a sewage recovery device at the bottom of the vehicle body. The sewage recovery device includes a device frame and a suction nozzle assembly arranged on the device frame. The suction nozzle The component is connected with the first chamber through the suction pipe, and the first chamber is connected with the blower. When in use, the suction nozzle assembly sucks garbage and sewage into the first chamber under the action of the fan, and the first chamber serves as a sewage tank to collect sewage, and the collected sewage can be reused after being filtered by the filter device.

However, the sewage recovery device on the above-mentioned cleaning vehicle is suspended and arranged on the vehicle body. If the road surface is uneven, the distance between the suction nozzle assembly and the road surface will change. If the distance is too large, the sewage on the road surface cannot be collected. Effective recycling, but if the spacing is too small, it is easy to bump and cause damage to the nozzle assembly, and the use effect is poor, and it is difficult to meet the use requirements of undulating road surfaces.
