Description

Technical Field

[0001] The utility model relates to the technical field of washing and sweeping vehicle parts, in particular to a high-pressure spray washing device for washing and sweeping vehicles. Background Art

[0002] The high-pressure spray washing device for washing and sweeping vehicles is a kind of equipment commonly used for cleaning urban roads, parks, squares and other places. It uses a high-pressure water gun to generate high-pressure water flow to wash away stains, dirt, fallen leaves and other debris on the ground. The device is generally installed on a washing and sweeping vehicle or a sweeping vehicle, which can improve cleaning efficiency and reduce the labor intensity of cleaners. In short, the high-pressure spray washing device for washing and sweeping vehicles is an efficient and convenient cleaning equipment, which is suitable for ground cleaning work in various places. It uses high-pressure water flow to wash away stains, which not only ensures environmental hygiene, but also reduces the labor intensity of cleaners and improves work efficiency.

[0003] According to the retrieval of China Utility Model Publication No.: CN219280590U, a high-pressure spray washing device for a washing and sweeping vehicle is disclosed. 1. The utility model discloses a high-pressure spray washing device for a washing and sweeping vehicle, one end of the swing arm is hinged to the fixed seat, and the fixed seat is fixed to the body of the washing and sweeping vehicle, so that the swing arm rotates around the connecting pin shaft, thereby driving the nozzle connected to the other end of the swing arm to move forward and backward, and the fixed seat and the swing arm are connected by the obstacle avoidance stretching spring in the obstacle avoidance stretching mechanism. Under the limiting action of the fixed seat and the obstacle avoidance stretching spring, the swing arm is tightened, so that the nozzle will not shake during normal spray washing work, and the work is more stable. When the swing arm or the nozzle encounters an obstacle when the washing and sweeping vehicle moves forward or backward, the obstacle avoidance stretching spring is deformed through the transmission of force, so that the swing arm can be rotated, thereby adjusting the position of the nozzle and the swing arm, realizing the obstacle avoidance function, and preventing the spray washing device from being damaged by collision.

[0004] However, there are some issues that need to be considered when implementing the above technical solution: first, the device cannot switch between different nozzles and cannot cope with more types of cleaning tasks, and has certain limitations; second, the device does not have a structure for mixing additives, and the cleaning ability of clean water is limited. If additives are mixed in the water tank in advance, it is easy to cause waste. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides an embodiment: a high-pressure spraying device for a washing and sweeping vehicle, comprising a clean water tank 1 and a spraying mechanism 3, a water tank cover 2 is arranged on the top of the clean water tank 1, the spraying mechanism 3 is arranged on the right side of the clean water tank 1, an additive barrel 301 is arranged on the right side of the clean water tank 1, and a barrel cover 302 is arranged on the top of the additive barrel 301.

[0026] Specifically, the additive barrel 301 is made of fiberglass, and the additive barrel 301 is threadedly connected to the barrel cover 302. A liquid level window 303 is provided on the surface of the additive barrel 301. Adding additives into the additive barrel 301 can enhance the cleaning ability of the high-pressure water flow, especially for oil stains, stubborn stains, etc., the additives can play a better role in decomposition and removal. The additive barrel 301 made of fiberglass has good resistance to most chemicals, including acids, alkalis, salts, etc.

[0027] Specifically, the right pipe of the additive barrel 301 is connected to the additive pump 304, and a water pump 305 is arranged on the front of the additive pump 304. The water pump 305 is connected to the clean water tank 1 by a pipe, and the right pipe of the water pump 305 is connected to the mixing barrel 306. The mixing barrel 306 and the additive pump 304 are connected by a pipe. The additive pump 304 and the water pump 305 work to send the additive and water into the mixing barrel 306 for mixing, thereby improving the cleaning efficiency.

[0028] Specifically, an impeller frame 307 is sleeved on the inner side of the mixing barrel 306, and a mixing impeller 308 is rotatably connected to the inner side of the impeller frame 307. Multiple groups of mixing impellers 308 are arranged, and adjacent mixing impellers 308 are in opposite directions. Water flows through the mixing impellers 308 to drive the mixing impellers 308 to rotate, mix the clean water and the additives, and play a good cleaning role. The opposite mixing impellers 308 can make the clean water and the additives mix more evenly.

[0029] Specifically, a rotating seat 309 is provided on the outside of the mixing barrel 306, and a rotating telescopic rod 310 is provided on the left side of the rotating seat 309. The rotating telescopic rod 310 is rotatably connected to the mixing barrel 306.

When light flushing is required, the first solenoid valve 314 is closed, the second solenoid valve 315 is opened, and the mixed liquid is sprayed from the spray head 317 for uniform coverage and light cleaning, or in situations where wetting is required but not strong flushing. The two nozzles can be used together to cope with more types of cleaning tasks.

[0032] Working principle: First, rotate the telescopic rod 310 to drive the left side of the mixing barrel 306 to change its position, so that the mixing barrel 306 rotates on the rotating seat 309 to adjust the vertical angle of the nozzle. At the same time, the motor 312 drives the turntable 311 to rotate to adjust the horizontal direction of the nozzle. Then the additive pump 304 and the water pump 305 work to send the additive and water into the mixing barrel 306 for mixing to improve the cleaning efficiency. The water flows through the mixing impeller 308 to drive the mixing impeller 308 to rotate, mix the clean water and the additive, and play a good cleaning role. The opposite mixing impeller Wheel 308 can make the clean water and additive mix more evenly. When heavy flushing is required, the first solenoid valve 314 is opened, the second solenoid valve 315 is closed, and the mixed liquid is sprayed out from the DC nozzle 316, which can quickly remove stubborn stains and loose objects. When light flushing is required, the first solenoid valve 314 is closed, the second solenoid valve 315 is opened, and the mixed liquid is sprayed out from the spray head 317 for uniform coverage and light cleaning, or in situations where moistening is required but not strong flushing. The two nozzles can be used together to cope with more types of cleaning tasks.
