[0019] In order to design a cleaning roller 4 with a simple structure and ensure that the cleaning roller 4 can pass through the glass plate 3, the cleaning roller 4 includes: a rod body 41 and two mounting shafts 40. Two mounting shafts 40 extend from both ends of the rod body 41, and each mounting shaft 40 extends into a slide rail 20. The cooperation between the slide rail 20 and the mounting shaft 40 ensures that the cleaning roller 4 moves on the specified path and that the cleaning roller 4 can pass through the glass plate 3, thereby ensuring a good cleaning effect.

[0020] In order to design a connecting mechanism 5 with a simple structure, the second elastic movable component 53 can be driven by driving a first elastic movable component 51. The connecting mechanism 5 includes: a first elastic movable component 51, a first elastic limiting component 52, a second elastic movable component 53 and a second elastic limiting component 54. The first elastic movable component 51 and the first elastic limiting component 52 are installed at the connection between a mounting shaft 40 and a stick body 41. A first elastic member is arranged in the first elastic movable component 51. The elastic force of the first elastic member can keep the first elastic movable component 51 inserted into the base 1. The first elastic limiting component 52 is used to keep the first elastic movable component 51 located in the mounting shaft 40 and the stick body 41; the second elastic movable component 53 and the second elastic limiting component 54 are installed at the top of the window. A second elastic member is arranged in the second elastic movable component 53. The elastic force of the second elastic member can keep the second elastic movable component 53 inserted into another mounting shaft 40. The second elastic limiting component 54 is used to keep the second elastic movable component 53 away from the mounting shaft 40.

[0021] The first elastic limiting assembly 52 and the second elastic limiting assembly 54 both include: a limiting pin 521 and a first spring 522, one end of the limiting pin 521 is used to act with the corresponding first elastic movable assembly 51 or second elastic movable assembly 53, the other end of the limiting pin 521 is fixed to one end of the first spring 522, and the other end of the first spring 522 is fixed to the window frame 2 or the base 1.

[0022] The first elastic movable component 51 includes: a toggle block 511, a first movable rod 512 and a second spring 513. The first movable rod 512 is installed in a mounting shaft 40 and a stick body 41. The first movable rod 512 can move relative to the stick body 41 and the mounting shaft 40 in a direction parallel to the stick body 41. The first movable rod 512 is fixed to one end of the second spring 513, and the other end of the second spring 513 is fixed to the inner wall of the stick body 41. The first movable rod 512 is fixed with a toggle block 511 extending out of the window frame 2. The first movable rod 512 is provided with a first limiting hole. The first limiting hole is used for inserting a limiting pin 521 in the first elastic limiting component 52. The second spring 513 is a first elastic member.

[0023] The second elastic moving component 53 includes: a second moving rod 531 and a third spring 532. Moving holes for the first moving rod 512 and the second moving rod 531 to move are opened in the stick body 41 and the two installation shafts 40. The base 1 is provided with a mounting cavity connected to the window. One end of the second moving rod 531 is used to extend into the moving hole to act with the first moving rod 512. The other end of the second moving rod 531 is located in the mounting cavity and fixed to one end of the third spring 532. The other end of the third spring 532 is fixed to the inner wall of the mounting cavity. The third spring 532 is a second elastic member. The second moving rod 531 is provided with a second limiting hole for the second elastic limiting component 54 to be inserted.

[0024] In order to design an elastic convolution mechanism 7 with a simple structure, the elastic convolution mechanism 7 includes: a convolution shell 71, a convolution cylinder 72, a central axis 73 and a coil spring 74. The convolution shell 71 is installed at the lower end of the window frame 2, and an inner cavity is installed in the convolution shell 71. The central axis 73 extends on the inner wall of the inner cavity. The convolution cylinder 72 is surrounded by the central axis 73. The convolution cylinder 72 rotates around the central axis 73 under the guidance of the inner wall of the convolution shell 71. A coil spring 74 is convoluted between the convolution cylinder 72 and the central axis 73. The inner end of the coil spring 74 is fixed to the central axis 73, and the outer end of the coil spring 74 is fixed to the convolution cylinder 72. The convolution cylinder 72 is used for convolution pull rope 6.

[0025] The working principle of this embodiment:

[0026] Generally, when the window door is in the state of closing the window, one end of the first moving rod 512 extends into the base 1 under the elastic force of the second spring 513, the limiting pin 521 of the first elastic limiting assembly 52 is pressed into the stick body 41, and the first limiting hole is located on the side of the first elastic limiting assembly 52 away from the second moving rod 531; under the elastic force of the third spring 532, one end of the second moving rod 531 extends into the moving hole, and the limiting pin 521 of the second elastic limiting assembly 54 is pressed into the base 1. At this time, the second limiting hole is located on the side of the second elastic limiting assembly 54 close to the first moving rod 512. At this time, the first moving rod 512 and the second moving rod 531 respectively hang the two mounting shafts 40 on the inner wall of the top of the window, thereby stabilizing the position of the cleaning roller 4.

[0027] When the window needs to be opened, the toggle block 511 is moved so that the first moving rod 512 moves into the stick body 41, and the second spring 513 is compressed. Since the second spring 513 hinders the movement of the first moving rod 512, the first moving rod 512 moves slowly. When the first limiting hole is aligned with the limiting pin 521 of the first elastic limiting assembly 52, there is enough time to realize that the elastic force of the first spring 522 decreases and the limiting pin 521 is inserted into the first limiting hole, thereby keeping the first moving rod 512 between the mounting shaft 40 and the fixing shaft 41. At the same time, the first moving rod 512 pushes the second moving rod 531 to move, and the third spring 532 is compressed. Since the third spring 532 hinders the movement of the second moving rod 531, the second moving rod 531 moves slowly. When the second limiting hole is aligned with the limiting pin 521 of the second elastic limiting assembly 54, there is enough time to achieve the elastic force of the first spring 522 to reduce the limiting pin 521 and insert it into the second limiting hole, thereby keeping the second moving rod 531 away from the mounting shaft 40 and the stick body 41. Subsequently, under the elastic force of the coil spring 74, the pull rope 6 is coiled, and at the same time, the cleaning roller 4 sweeps across the glass plate 3 to achieve cleaning.

[0028] When closing the window, first, rotate the window to the position of closing the window; then, pull the cleaning roller 4 to the top of the window, and the window frame 2 is provided with an L-shaped slide groove for the sliding block 511 to slide; then, by toggling the toggle block 511, the first moving rod 512 continues to move toward the second moving rod 531, the second spring 513 and the third spring 532 are both compressed, the first limiting hole and the second limiting hole are both disengaged from the limiting pin 521, and the second spring 513 and the third spring 532 both store a large elastic potential energy; finally, release the toggle block 511, and the second spring 513 and the third spring 532 are in the state of being opened. Under the elastic force of the spring 513, the first moving rod 512 is inserted into the base 1, and under the elastic force of the third spring 532, the second moving rod 531 is inserted into the moving hole in the stick body 41. Since the movement of the first moving rod 512 and the second moving rod 531 is not hindered at this time, the first moving rod 512 and the second moving rod 531 move at a faster speed, so the limit pin 521 does not have time to be inserted into the first limit hole and the second limit hole. The first limit hole and the second limit hole both pass over the corresponding limit pin 521, thereby supporting the two mounting shafts 40, thereby stabilizing the window door in a closed state.

[0029] First, in order to facilitate observation of the situation in the pit, a window door with a glass plate 3 is designed. The window door is set at the top of the pit and does not hinder the water accumulation at the bottom of the pit; then, when the water in the pit needs to be cleared after the water accumulation test, a window door with an openable window is designed; then, because the water is not clean after passing through the car, etc., splashing on the glass plate 3 will block the line of sight, so a cleaning roller 4 is designed; then, in order to facilitate cleaning of the glass plate 3, an elastic convolution mechanism 7 and a connecting mechanism 5 are designed. The connecting mechanism 5 connects the window door to the base 1 and at the same time, the cleaning roller 4 is designed. The sweeping roller 4 is hung on the top. When the window door is opened, the elastic convolution mechanism 7 can sweep the glass plate 3. When the window door is closed, the sweeping roller 4 needs to be pulled to the top of the window door so that the connecting mechanism 5 can be connected to the base 1. Then, in order to stably hang the sweeping roller 4 on the top of the window, a first elastic movable component 51 and a second elastic movable component 53 are designed to support both mounting shafts 40. Finally, by adjusting the first elastic movable component 51, the second elastic movable component 53 can be adjusted, which facilitates the adjustment.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
