[0036] Embodiment
[0037] As shown in Figure 1 、 Figure 2 、 Figure 3 , a building outer wall cleaning equipment, including sling mechanism 1, cleaning mechanism 2 and push mechanism 3.
[0038] As shown in Figure 3 , the sling mechanism 1 is used for fixing at the top of the building outer wall, and the sling mechanism 1 has a sling rope 10, which is used for ascending and descending along the building outer wall. The cleaning mechanism 2 includes a hanging part 21 and a rolling brush piece: the hanging part 21 is hung on the sling rope 10; the rolling brush piece is arranged on the hanging part 21 and is used for cleaning the building outer wall. The push mechanism 3 includes at least one wind pressure piece 30, which is arranged on the hanging part 21 and is used for applying wind pressure to the hanging part 21 so that the hanging part 21 moves to the direction close to the building outer wall. Wherein, the wind pressure piece 30 of the embodiment adopts a commercially available fan.
[0039] Preferably, as shown in Figure 3 , the hanging part 21 includes a main beam 211 and a side plate 212. The main beam 211 is connected with the suspension end of the sling rope 10. The side plate 212 has two, and the two side plates 212 are arranged at the two ends of the main beam 211 respectively; the rolling brush piece is arranged between the two side plates 212 and located at the side of the side plate 212 close to the building outer wall; the wind pressure piece 30 is arranged between the two side plates 212 and located at the side of the side plate 212 away from the building outer wall.
[0040] Preferably, as shown in Figure 1 ,Figure 2 , Figure 3 As shown, the side plate 212 has an inverted T-shaped or inverted Y-shaped structure, with the long side of the inverted T-shaped or inverted Y-shaped structure connected to the main beam 211. The roller brush is fixed to the short side of the side plate 212 closest to the building's exterior wall; an auxiliary beam 213 is provided between the other short sides of the two side plates 212, and the wind pressure component 30 is mounted on the auxiliary beam 213. This inverted T-shaped or inverted Y-shaped structure has two main effects: first, the center of gravity is lowered, allowing for horizontal stability by suspending it at the center of the upper end of the main beam 211 with the sling rope 10; second, the roller brush is the only point of contact with the wall, making it easier to overcome obstacles as it will not come into contact with any other components besides the roller brush. In this embodiment, the side plate 212 adopts an inverted T-shaped structure.
[0041] Preferred, such as Figure 3 As shown, the roller brush assembly includes a roller brush 22 and a roller brush motor 23. The roller brush 22 is rotatably mounted between two side plates 212 for brushing the exterior walls of a building. The roller brush motor 23 is fixed to either side plate 212 and connected to the roller brush 22 to drive its rotation. It should be noted that in this embodiment, the outer layer of the roller brush 22 is a plush layer made of plush material. Due to the elasticity of the material, the plush layer also has a certain amount of compressibility. The roller brush motor 23 is a commercially available motor.
[0042] Preferably, a drain pipe is embedded in the side wall of the main beam 211 near the building's exterior wall. A booster pump is installed at the inlet end of the drain pipe, connecting to an external water source. A nozzle is installed on the drain pipe to spray water onto the building's exterior wall. By using the drain pipe, nozzle, and booster pump in conjunction with an external water source, the exterior wall can be sprayed and washed. Combined with the brushing function of the roller brush, the cleaning effect can be effectively improved. In this embodiment, when using an external water source to spray and wash the wall, it is recommended to clean from top to bottom to avoid the possibility that cleaning from bottom to top will result in the upper exterior walls being washed later, causing the dirty water to affect the cleanliness of the lower exterior walls.
[0043] Preferably, the booster pump is connected to an external water source via a hose, the length of which corresponds to the length of the sling rope 10. Since the sling mechanism 1 suspends the cleaning mechanism 2 and the pushing mechanism 3 via the sling rope 10, during the cleaning of the external wall, the length of the sling rope 10 is changed to position the cleaning mechanism 2 and the pushing mechanism 3 at different heights on the external wall. Therefore, the length of the hose needs to correspond to the length of the sling rope 10 to ensure that the hose maintains the connection between the booster pump and the external water source during the raising and lowering of the cleaning mechanism 2 and the pushing mechanism 3.
[0044] Preferably, the axis of the rolling brush 22 is on the same horizontal line as the installation position of the air pressure device 30. This structure can satisfy the use of a single sling rope 10 to achieve stable hanging of the cleaning mechanism 2 and the pushing mechanism 3, and in actual use, the air pressure provided by the air pressure device 30 can make the rolling brush 22 bear force on the same height horizontal line, thereby closely contacting the external wall.
[0045] Preferably, the air pressure device 30 has 2-5, and the air pressure device 30 in the embodiment has 2.
[0046] Preferably, a smart control module is further included, which includes a controller and a sensing device. The controller is electrically connected with the sling mechanism 1, the rolling brush motor 23, the booster pump, and the air pressure device 30. The controller in the embodiment adopts a commercially available controller with human-computer interaction, which is connected with a remote controller through a wireless module or connected with a mobile terminal through an APP. The sensing device is electrically connected with the controller and arranged on the hanging part 21, and is used for detecting whether there is an obstacle on the external wall of the building. The sensing device is installed on the side plate 212 without the motor 23, and the direction of the detection distance is vertically downward. The sensing device in the embodiment adopts a commercially available distance sensor. It should be noted that the sensing device can also adopt a contact type switch, ultrasonic wave, and infrared sensor, and the main function is to maintain the contact degree of the rolling brush with the upper surface of the obstacle
[0047] The working method of the above embodiment is as follows:
[0048] The sling mechanism 1 is fixed on the top of the external wall of the building. After the equipment is in place, the air pressure device 30 is started to generate a positive pressure facing the wall surface, so as to make the rolling brush 22 closely contact the external wall of the building. The rolling brush motor 23 is started, and the rolling brush 22 is used to sweep the external wall of the building. In use, the booster pump can also be used to introduce the external water source into the drain pipe, and the nozzle is used to wash the external wall of the building, so as to improve the cleaning effect. The tightening or releasing of the sling rope 10 by the sling mechanism 1 can realize the up and down movement of the sling rope 10 along the external wall of the building, so as to complete the cleaning of the flat wall surface part.
[0049] As shown in Figure 4 , Figure 5 , Figure 6 When the sensing device detects that the rolling brush 22 contacts the obstacle on the external wall of the building, the controller controls the sling mechanism 1 to stop releasing the sling rope 10, and then continuously releases the sling rope 10 after the air pressure device 30 is closed. When the sensing device detects that the rolling brush 22 moves beyond the upper edge of the obstacle, the air pressure device 30 is opened. When the operation reaches the lower edge of the obstacle, the rolling brush 22 reapproaches the wall surface and continues the cleaning operation due to the action of the air pressure device 30, and the obstacle crossing operation is completed.
[0050] It should be noted that when the external wall of the building is cleaned from bottom to top, the working method is similar to the above working method.
[0051] In addition, the rotation direction of the rolling brush 22 is clockwise rotation, and in actual use, a bidirectional rotation circuit of the motor can be additionally provided to satisfy the forward and reverse rotation of the rolling brush motor 23, when the equipment moves downward, the rolling brush 22 rotates clockwise to correspond to the downward movement of the equipment, when the equipment moves upward, the rolling brush 22 rotates counterclockwise to correspond to the upward movement of the equipment.
[0052] The specific models of the above-mentioned electronic components are not specially specified, and common products on the market can be selected as long as they can meet the use requirements of the utility model.
[0053] The above-described specific embodiments further specifically describe the purpose, technical solutions and beneficial effects of the utility model, and it should be understood that the above-described specific embodiments are only specific embodiments of the utility model, and do not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model are included in the protection scope of the utility model.
