[0003] Generally, transport vehicles will pass through the gantry type car washing machine, and the top spray device will spray the transport vehicles passing below. However, this method is prone to cause a lot of water waste. During the spraying process, most of the water mist is not sprayed on the vehicle body. The water mist spreads around into the air or on the ground, resulting in unnecessary waste of water resources and is difficult to recycle. Utility Model Content

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The embodiment of the present application discloses a closed type spray car washing device.

[0030] refer to Figure 1 and Figure 2 The closed spray car washing device includes a spray box 1, a spray device 2 and a closing component 4. The spray box 1 is a box structure with openings only at both ends, and the interior is large enough for a transport vehicle to enter and stay. The spray device 2 is installed on the top wall and the inner side wall of the spray box 1, and the water tank of the spray device 2 is located on the top of the spray box 1. A collecting water tank 11 is installed at the bottom of the spray box 1, and a drainage board 111 is provided on the top of the collecting water tank 11. The drainage board 111 can support the weight of the transport vehicle, and the transport vehicle enters the spray box 1 and is also located on the drainage board 111. Closing components 4 that can close the spray box 1 are provided at the openings at both ends of the spray box 1.

[0031] After the transport vehicle enters the spray box 1, the openings at both ends of the spray box 1 are closed by the closing component 4, and then the transport vehicle is sprayed by the spray device 2. The water mist that does not fall on the transport vehicle will fall on the inner wall of the spray box 1, and then fall into the collection tank 11, so as to recycle water resources and reduce the waste of water resources.

[0032] refer to Figure 2 and Figure 3 The closing assembly 4 includes a driving rod 41, a driving block 42 and a folding curtain 43. The driving rod 41 is rotatably mounted on the top of the two openings on the inner wall of the spray box 1, and opposite threads are distributed from the middle to both sides. A driving motor 3 is installed on the outer wall of the spray box 1 to drive the driving rod 41 to rotate. Two driving blocks 42 are in a group, which are installed on the threads of different rotation directions of the driving rod 41, and the positions are symmetrically set with respect to the midpoint of the driving rod 41. The driving blocks 42 are threadedly connected with the threads on the driving rod 41. The top of the driving block 42 is in close contact with the inner top wall of the spray box 1. Two folding curtains 43 are hung on the driving rod 41 in a group, and the folding curtains 43 can slide on the driving rod 41. One end of the folding curtain 43 is fixedly connected to the inner wall of the spray box 1, and the other end is fixedly connected to the driving block 42. The folds of the folding curtain 43 are arranged vertically, and the main body of the folding curtain 43 is a waterproof material, which is a transparent PVC material in this embodiment. A plurality of support blocks 431 are fixedly arranged on one side of the folding curtain 43 facing the spray box 1 near the fold. A plurality of air holes 432 are provided on the folding curtain 43, and the air holes 432 are arranged upwardly inclined from the side close to the inside of the spray box 1. An interception groove 12 is provided at the bottom of the spray box 1 opposite to the folding curtain 43, and the bottom of the folding curtain 43 is located in the interception groove 12. The bottom of the interception groove 12 is connected to the collection water tank 11, and the inner bottom wall of the interception groove 12 is arranged downwardly inclined toward the collection water tank 11.

[0033] After the transport vehicle enters the spray box 1, the driving motor 3 drives the driving rod 41 to rotate, thereby driving the two driving blocks 42 to approach each other, and the driving block 42 drives the folding curtain 43 to unfold, and then the openings at both ends of the spray box 1 are closed by the folding curtain 43. Due to the material of the folding curtain 43, the water mist falling on the folding curtain 43 is intercepted by the folding curtain 43. The folding curtain 43 can also allow light to pass through, thereby increasing the brightness in the spray water tank. The setting of the support block 431 can reduce the situation where the wet parts of the folding curtain 43 stick together after being folded, and can also increase the area of ​​the space where air circulates after folding, which is convenient for unfolding. The setting of the air vent 432 can improve the efficiency of air circulation between the spray box 1 and the outside world, and can also improve the efficiency of water evaporation on the folding curtain 43, reduce the probability of the folding curtain 43 getting moldy, and at the same time, it can also reduce the probability of the water mist in the spray box 1 flowing to the outside world by setting the opening direction, while maintaining ventilation and reducing the waste of water resources.

[0034] The interception groove 12 can effectively stabilize the movement of the bottom of the folding curtain 43 and reduce the probability of being blown by the wind. At the same time, it can also make the water flowing down from the folding curtain 43 flow to the interception groove 12 and flow into the collection water tank 11, thereby improving the efficiency of water recovery on the folding curtain 43.

[0035] The implementation principle of a closed spray car washing device in the embodiment of the present application is as follows: after the transport vehicle enters the spray box 1, the driving motor 3 drives the driving rod 41 to rotate, thereby driving the driving block 42 to move, unfolding the folding curtain 43, and then closing the openings on both sides of the spray box 1. In the subsequent spraying process, the water sprayed on the transport vehicle falls on the spray box 1 and the folding curtain 43, and flows downward to the collection tank 11 for collection, thereby reducing the waste of water resources and improving the utilization rate of water resources.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
