With the popularization of sanitation trucks, China has a large number of sanitation trucks working on the road every day, and as a watering cart, the length of time that the sanitation truck can continuously work after being added with water once is an important index for measuring the performance of the sanitation truck. At present, the main idea of increasing the working time of the sanitation vehicle after water is added once in the industry is to increase the volume of a water storage tank so that the sanitation vehicle can store more water, namely, the working time of the sanitation vehicle after water is added once is prolonged by enabling the sanitation vehicle to carry more water. However, the water storage tank of the sanitation vehicle cannot be infinitely enlarged due to the restrictions of relevant policies and standards, and the way of lengthening the working time of single water adding by enlarging the water storage tank has certain limitations. In addition, in the process of enlarging the water storage tank, a problem is always accompanied, namely after the water storage tank is enlarged, the extension amount of the working time of the sanitation truck after single water adding does not reach the expectation, a certain difference always exists between the extension amount and the expectation, and the difference is increased along with the increase of the volume of the water storage tank. After repeated research and analysis, the applicant of the present invention finds that the main reason for the above problem is that a large vortex is formed at the water outlet of the water storage tank in the water outlet process, and when the generation of the vortex directly causes a large amount of water in the water storage tank, the water pump connected to the water outlet enters air, and thus the water pump cannot normally continue to work. Based on the discovery, the vortex preventing device is arranged at the water outlet in the tank body of the water storage tank, so that the problem of low water discharge rate of the water storage tank of the sanitation vehicle is solved, and the working time of the sanitation vehicle after single water adding is prolonged.
The features and properties of the water storage tank for sanitation vehicle according to the present invention will be described in further detail with reference to the following embodiments.

When a conventional sanitation truck works, clear water in the tank body 101 flows to a pipeline and a water pump through the water outlet 19 of the tank body, the flow rate of the clear water flowing through the pipeline and the water pump is basically 600-1000L/min, at the moment, huge vortexes are formed above the water outlet 19 in the tank body, when the water level in the tank body is reduced to a certain degree, air in the middles of the vortexes starts to be sucked into the pipeline and enters the water pump, the sucked air is mixed with the clear water to cause cavitation erosion to the water pump, so that faults are caused, and the watering and dust-settling effects of the sanitation truck are poor; by using the water storage tank for the sanitation vehicle, as the barrel body 12 of the tank body 101 is of an ellipse-like structure, the water level height of the tank body 101 is continuously reduced during the operation of the sanitation vehicle, and the area of clear water corresponding to the height is smaller and smaller, so that the height of the clear water in the tank body can be reduced when a water pump of the sanitation vehicle starts to suck air, the residual water quantity of the tank body can be obviously reduced, the shaking of the water level during the running operation of the sanitation vehicle is considered, the shaking of the clear water in the tank can be reduced by adding the wave-preventing plate 14, and the influence of the braking or starting of the vehicle on the water level height is reduced. Round holes with the diameter of 6mm are distributed on the peripheral side plate 21 of the vortex prevention device, and the round holes can filter out welding slag and other solid impurities at the bottom of the tank body, so that the water filter is prevented from being blocked by larger impurities and even the water pump is prevented from being damaged; the flat top plate 22 and the guide plate 23 can reduce the intensity of the swirl, reduce the height of the formed swirl, improve the effective utilization rate of clear water in the tank body 101, prolong the single water adding operation time and improve the operation efficiency of the sanitation truck. After the vortex-preventing filtering device is added above the water outlet of the tank body 101, the utilization degree of clean water in the tank body 101 is increased, the daily water adding frequency can be reduced to a certain degree, more water discharging time can be saved when a user drains water in winter, and the using efficiency of the sanitation truck is improved.
In other embodiments of the water storage tank for the sanitation vehicle, the tank body front sealing plate and the tank body rear sealing plate can also be flat plates or circular arc plates formed by stamping. The tank body can be provided with water filling ports on the left side and the right side respectively, so that water can be added to the left side and the right side of the tank body simultaneously, and convenience is improved. The tank body top cover can be omitted, and when a user has a demand, the corresponding tank body top cover can be additionally arranged by self. The peripheral side plate of the vortex preventing device can be round or in other shapes besides the square shape in the above embodiment, and the guide plate in the vortex preventing device can be a plate with a part of curved surface characteristics besides the flat plate in the above embodiment.
