In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited to the basic implementation disclosed below.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 A rectangular shielding shell 1 is provided, which opens to the right. A water storage tank 2 with an upward opening is provided at the lower end of the shielding shell 1. A rectangular main flow pipe 3 is provided on the left side of the shielding shell 1. The right end of the main flow pipe 3 is connected with horizontal spray pipes 4 in four directions of up, down, front and back, and the left side of the main flow pipe 3 is connected with a front spray pipe 5 in the vertical direction. A rear spray pipe 6 located on the right side of the horizontal spray pipe 4 and in the vertical direction is provided in the shielding shell 1. The rear spray pipe 6 is rotatable. A plurality of spray heads 7 are provided on the horizontal spray pipe 4, the front spray pipe 5 and the rear spray pipe 6. The right end of the upper horizontal spray pipe 4 is connected with the upper end of the rear spray pipe 6 through a hose 8. A water pump 9 is provided on the left end of the water storage tank 2. A water inlet pipe 10 inserted into the main flow pipe 3 is provided on the right end of the water pump 9. A water suction pipe 11 inserted into the water storage tank 2 is provided on the left end of the water pump 9.

[0016] In order to facilitate the spraying test on the lower end of the motor vehicle, a rectangular spraying slot 12 is provided at the lower end of the shielding shell 1.

[0017] In order to make the rear spray pipe 6 rotatable, an L-shaped rotating plate 13 is provided at the front end of the rear spray pipe 6, and a rotating shaft 14 rotatable in a front-to-rear axial direction is provided at the front end of the rotating plate 13.

[0018] In order to rotate the rotating shaft 14 , a motor 15 is provided at the front end of the shielding shell 1 , and the output shaft of the motor 15 is coaxially fixedly connected with the rotating shaft 14 .

[0019] For ease of use, the lower end of the shielding shell 1 is flush with the ground, and the water tank 2 is located below the ground.

[0020] In order to prevent interference when the rear spray pipe 6 rotates, the center of the rotating shaft 14 is the intersection point of the axis of the upper lateral spray pipe 4 and the axis of the rear spray pipe 6.

[0021] When the utility model is used, the vehicle to be detected is first driven into the shielding shell 1. In order to prevent the rear spraying pipe 6 from blocking the vehicle from entering the shielding shell 1, the operator starts the motor 15 to rotate forward, and the motor 15 drives the rotating shaft 14 to rotate counterclockwise. The rotating shaft 14 drives the rear spraying pipe 6 to rotate counterclockwise through the rotating plate 13. After rotating 90 degrees, the motor 15 is turned off. At this time, the rear spraying pipe 6 changes from the state of the upper and lower axial direction to the state of the left and right axial direction, and the shielding of the right opening of the shielding shell 1 is released. At this time, the vehicle can be driven into the shielding shell 1, and the wheels on both sides are located on both sides of the spraying slot 12;

[0022] When the car enters the shielding shell 1, the motor 15 is turned on to reverse, and the motor 15 drives the rotating shaft 14 to rotate clockwise, and the rotating shaft 14 drives the rear spray pipe 6 to rotate clockwise. After rotating 90 degrees, the motor 15 is turned off. At this time, the rear spray pipe 6 rotates from the left and right axial state to the initial state of the upper and lower axial state. At this time, the water pump 9 can be turned on. The water pump 9 absorbs water from the water storage tank 2 through the water suction pipe 11 and injects it into the main flow pipe 3 through the water inlet pipe 10. The water in the main flow pipe 3 enters into multiple horizontal spray pipes 4 and the front spray pipe 5 due to pressure, and at the same time enters into the rear spray pipe 6 through the hose 8, and then sprays out through the spray head 7, so as to realize the comprehensive spraying test of the six surfaces of the motor vehicle;

[0023] The sprayed water flows back into the water storage tank 2 through the spraying trough 12, and is sucked and sprayed again by the water pump 9. This process is repeated to achieve recycling and save water resources. After the test is completed, the motor 15 is turned on again to rotate forward, so that the rear spraying pipe 6 rotates to the left and right axial directions to remove the obstruction to the exit, and then the test vehicle is driven out of the shielding shell 1.

[0024] Compared with the prior art, the beneficial effects of the utility model are: the horizontal spray pipe, spray head, etc. can realize the all-round spraying and rain simulation of the test vehicle, making the test data more accurate and comprehensive, and at the same time the waste water can be collected and reused to save water resources. The structure is simple, the concept is novel, the use is convenient and the practicability is strong.

[0025] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0026] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
