[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a building exterior window water spraying experimental device, such as Figure 1 and 2 As shown, it includes a hoisting assembly 2, a mounting frame 3, a spray assembly 4 and a positioning mechanism 5. The hoisting assembly 2 is used to hoist the mounting frame 3 and move the mounting frame 3 vertically along the outer wall of the building 1. The spray assembly 4 is used to supply water to the mounting frame 3 so that the mounting frame 3 can spray the outer windows of the building 1. The positioning mechanism 5 is used to position the mounting frame 3 and a single window opening 11 of the building 1 relative to each other before the spraying starts, and to improve the position stability of the mounting frame 3 and the window opening 11 during the spraying process.

[0023] like Figure 1 and 2 As shown, the spray assembly 4 includes a water pump, a water supply pipe 41 and a water spray pipe head 42. There are multiple water spray pipe heads 42 and they are installed on the side of the installation frame 3 facing the building 1. One end of the water supply pipe 41 is connected to the water spray pipe head 42, and the other end is connected to the water pump. The water pump is located on the top of the building 1, which is not shown in the figure. The installation position of the water spray pipe head 42 needs to be adjusted according to the size adaptability of the window opening 11 and the window frame. When the positioning mechanism 5 completes the positioning of the installation frame 3 relative to the window opening 11, the water spray pipe head 42 is just aligned with the gap between the window and the window frame.

[0024] like Figure 1 and 2As shown, the hoisting assembly 2 includes a main hoisting rope 22, one end of which is pulled and fixed by a winch 21 located on the roof, and the other end is fixedly connected to the mounting frame 3. The positioning mechanism 5 includes a detection sensor 51, an abutment member 52 and a driving source 53. The detection sensor 51 is connected to the mounting frame 3 and is used to detect the relative position of the mounting frame 3 relative to the upper edge of the window opening 11. In this embodiment, the detection sensor 51 can be a distance sensor, and its signal emission direction is perpendicular to the outer wall surface of the building 1. During the vertical movement of the mounting frame 3, if the distance measured by the distance sensor changes suddenly, it can indicate the relative position of the mounting frame 3 and the window opening 11. The abutment member 52 is movably connected to the mounting frame 3, and the driving source 53 is used to control the movement of the abutment member 52; there are two abutment members 52, and the detection sensor 51 is electrically connected to the driving source 53. When it is detected that the detection sensor 51 itself is located at the same height as the upper edge of the window opening 11, the detection sensor 51 sends a start signal to the driving source 53, so that the two abutment members 52 are respectively abutted against a single inner wall of the window opening 11.

[0025] like Figure 2 and 3 As shown, the abutment 52 is hinged to the mounting frame 3, the driving source 53 is a driving cylinder, the driving cylinder is hinged to the mounting frame 3, the piston rod of the driving cylinder is hinged to the abutment 52, the hinge axes among the three are all in the vertical direction, and the axis of the driving cylinder is in the horizontal direction. When the piston rod of the driving cylinder is extended, it pushes the abutment 52 to swing toward the building 1. The abutment member 52 includes a support frame 521 and an abutment channel steel 522, the hinge axis of the abutment member 52 is located at one end of the support frame 521, the abutment channel steel 522 is located at the end of the support frame 521 away from the mounting frame 3 and the two are slidably connected; the length direction and the relative sliding direction of the abutment channel steel 522 are both vertical directions. After the abutment member 52 is flipped into the window hole 11, the side of the abutment channel steel 522 facing the inner wall of the window hole 11 is fixedly connected with a first friction pad 523, the first friction pad 523 is in direct contact with the inner wall of the window hole 11, and the propulsion force of the driving cylinder finally makes the first friction pad 523 and the inner wall of the window hole 11 tightly abut. A second friction pad 524 is fixedly connected to the lower end of the support frame 521 near the side abutting the channel steel 522. After the first friction pad 523 maintains contact with the inner wall of the window opening 11, the lower end of the support frame 521 is still 3-5 cm away from the bottom wall of the window opening 11. At this time, the winch 21 continues to lower the installation frame 3 until the second friction pad 524 contacts the lower side wall of the window opening 11. Therefore, when the oil pressure of the two driving cylinders is equal, the relative position certainty and position stability of the installation frame 3 and the window opening 11 are relatively high.

[0026] like Figure 1 , 2As shown in Figure 3, since the abutment 52 cooperates with the inner wall of the window opening 11, before the positioning mechanism 5 is started, determining the relative distance between the mounting frame 3 and the side wall of the building 1 is a prerequisite for the successful flipping and positioning of the abutment 52. The experimental device also includes an auxiliary component 6, which includes an air pump, an air supply pipe 61 and an air jet pipe 62. The air jet pipe 62 is rotatably connected to the mounting frame 3. An air jet hole 621 is provided on the side wall of the air jet pipe 62. One end of the air supply pipe 61 is connected to the air pump, and the other end is connected to the mounting frame 3. The air supply pipe 61 is connected to the air jet pipe 62. The length direction and the rotation axis of the air jet pipe 62 are both vertical. The air pump is located at the top of the building 1, which is not shown in the figure. Before the positioning mechanism 5 is started, the air jet hole 621 on the air jet pipe 62 faces the side away from the building 1. A plurality of adjusting balls 31 are embedded on the side of the mounting frame 3 facing the building 1. After the air pump is started, the air jet pipe 62 ejects gas toward the side away from the building 1, and the mounting frame 3 is subjected to a reaction force and leans against the side wall of the building 1. At this time, the relative position of the mounting frame 3 and the side wall of the building 1, i.e., the edge of the window opening 11, is also determined.

[0027] like Figure 2 , 3 As shown in 4, the controlled rotation angle of the jet pipe 62 is 180°, and a control assembly 7 for controlling the rotation of the jet pipe 62 is provided on the mounting frame 3. The control assembly 7 includes a control gear 72, a control rack 71 and a plurality of reversing gear sets 73. The control rack 71 is slidably connected to the mounting frame 3, and the sliding direction is vertical. The control gear 72 is rotatably connected to the mounting frame 3, and the control rack 71 is meshed with the control gear 72. The number of the reversing gear sets 73 and the jet pipes 62 is consistent and the two correspond one to one. In this embodiment, the number of the jet pipes 62 is two, and the two jet pipes 62 are respectively located on both sides of the control gear 72. The control gear 72 transmits torque to the jet pipe 62 through the reversing gear set 73. The lifting assembly 2 also includes an auxiliary lifting rope 23. One end of the auxiliary lifting rope 23 is pulled and fixed by another winch 21 located on the roof, and the other end is fixedly connected to the upper end of the control rack 71. The lower end of the control rack 71 is fixedly connected to a counterweight block 711, that is, an upward pulling force is applied to the control rack 71 through the auxiliary lifting rope 23 to move the control rack 71 relative to the mounting frame 3. An auxiliary tension spring 74 is connected between the control rack 71 and the mounting frame 3, and the extension and contraction direction of the auxiliary tension spring 74 is parallel to the length direction of the control rack 71; when the jet hole 621 is facing the side away from the building 1, the control rack 71 applies an upward pulling force to the mounting frame 3 through the auxiliary tension spring 74, and the counterweight block 711 abuts against the bottom edge of the mounting frame 3, that is, at this time, the auxiliary suspension rope 23 and the main suspension rope 22 together suspend the mounting frame 3; when the jet hole 621 is facing the building 1, the tension of the auxiliary suspension rope 23 on the control rack 71 is zero, that is, at this time, the gravity of the control rack 71 and the counterweight block 711 is all borne by the mounting frame 3.

[0028] The implementation principle of the building exterior window water spraying experimental device in the embodiment of the present application is: When the installation frame 3 is moving vertically, the abutment 52 is against the installation frame 3, the water supply pipe 41 is closed, the jet pipe 62 sprays air to the side away from the building 1, and the installation frame 3 moves close to the wall of the building 1. When the detection sensor 51 detects that it is located at the upper edge of the window hole 11, the vertical movement of the installation frame 3 stops, the abutment 52 is turned over, and the two abutment members 52 abut against the side wall of the window hole 11. At this time, the lateral position of the installation frame 3 is determined, and then the installation frame 3 is lowered until the support frame 521 contacts the bottom wall of the window hole 11. At this time, the relative position of the installation frame 3 and the window hole 11 is determined, and the spraying experiment can be carried out. Due to the abutment and friction between the abutment 52 and the inner wall of the window opening 11, the mounting frame 3 and the building 1 remain relatively stable. The control rack 71 is moved by the auxiliary suspension rope 23, so that the weight of the control rack 71 and the counterweight block 711 falls on the mounting frame 3, further improving the stability of the mounting frame 3. At the same time, the jet hole 621 of the jet pipe 62 jets air toward the window, thereby understanding the impact of windy weather on the sealing of the window.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
