Description

Technical Field

[0001] This application relates to the technical field of building walls, and in particular to a cleaning device for green building walls. Background Art

[0002] With the enhancement of the national environmental protection awareness and the scarcity of urban land resources, in order to further improve the urban greening rate, each region will adjust measures to local conditions, combine the climate, environment, resources, economy, culture and other characteristics of the building location, make full use of the building space, and provide people with a high-quality green building that is healthy, applicable and maximally realizes the harmonious coexistence of man and nature.

[0003] Common green buildings, in order to embody the environmental protection concept of reducing pollution, will choose to set planting grooves on the outer wall of the building wall. The bottom of the planting groove is provided with filter holes, and then green plants are planted in the planting groove. Multiple layers of planting grooves are arranged on the building wall, so that the traditional building wall can be effectively transformed into a green building wall with the concept of green environmental protection.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when green plants are planted in layers on the building wall, the green plants can adsorb the dust flying in the air or attract some mosquitoes and flies between the stems and leaves of the green plants. Affected by the long-term planting of green plants, dust or mosquitoes may also adhere to the building wall; during the rainy season, although the rainwater can wash the planting groove and wash away the dust or mosquitoes, due to the blockage of the planting groove, the wall between adjacent planting grooves cannot be washed, and when the planting groove is washed by the rainwater, muddy water may flow out from the bottom of the planting groove and then flow down along the wall, further polluting the wall, which greatly affects the beauty. Therefore, further improvement is needed. Summary of the Invention

[0005] In order to improve the problem that the wall is polluted and affects the beauty of the building, this application provides a cleaning device for green building walls.

Detailed implementation manners

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] An embodiment of the present application discloses a cleaning device for the wall 1 of a green building. Referring to Figure 1 and Figure 2 , in this embodiment, in order to clean the wall surface of the wall 1 between two adjacent planting troughs 10 on the wall 1 of the green building and reduce the situation that more dust and mosquitoes on the wall 1 affect the appearance, therefore, a cleaning brush 2 is slidably connected between two adjacent planting troughs 10 on the wall 1, and a spray head 3 for spraying the wall surface of the wall 1 is provided on the wall 1; during use, the wall surface can be cleaned by the cleaning brush 2, and then the wall surface of the wall 1 is sprayed by the spray head 3, so that the dirt adhered to the wall 1 between the adjacent planting troughs 10 can be effectively cleaned, improving the appearance of the wall 1;

[0037] In addition, a driving component for driving the cleaning brush 2 to horizontally slide along the wall 1 is further provided on the wall 1. Driving the cleaning brush 2 to slide by the driving component can increase the cleaning range of the cleaning brush 2, so that the entire horizontal wall surface of the wall 1 between the adjacent planting troughs 10 can be cleaned. And a water supply component for supplying water to the spray head 3 and a water storage component for providing water source for the water supply component are provided on the wall 1. The water storage component can store water source and then supply it to the water supply component, and then the water supply component transfers it to the spray head 3 to ensure that the wall surface can always be sprayed during the cleaning of the wall 1, improving the cleaning effect of the wall 1;

[0038] Referring to Figure 1 and Figure 3, in this embodiment, a drainage assembly for draining sewage is further provided on the wall 1 near the top of the planting groove 10. The drainage assembly includes a water receiving groove 9 which is arranged on the wall 1 near the top of the planting groove 10, and the cross-section of the water receiving groove 9 is U-shaped. A drainage pipe 90 communicating with the water receiving groove 9 is arranged at any end of the wall 1 where the water receiving groove 9 is located, and the water receiving groove 9 is inclined towards the drainage pipe 90. The sewage generated when cleaning the wall 1 can be received by the water receiving groove 9, and then the sewage is discharged by the drainage pipe 90. The length extension direction of the drainage pipe 90 is the same as the height extension direction of the wall 1. Using the water receiving groove 9 and the drainage pipe 90 can effectively reduce the situation that sewage drops into the planting groove 10 and affects the growth of green plants. A bracket 100 is also connected between the planting groove 10 and the wall 1. Through the connection of the bracket 100, a certain gap can be reserved between the planting groove 10 and the wall 1, which can not only reduce the situation that the wall 1 gets damp due to the long-term use of the planting groove 10, but also reduce the situation that the sewage drops into the planting groove 10 during cleaning.

[0039] Refer to Figure 1 and Figure 2 and Figure 3 , in this embodiment, the driving assembly is arranged as follows: a lead screw 4 rotatably connected between two adjacent planting grooves 10 on the wall 1 and a driving member for driving the lead screw 4 to rotate; the driving member includes a rotating rod 5 arranged on the wall 1 and a servo motor 50 for driving the rotating rod 5 to rotate. The servo motor 50 is connected to the top of the wall 1, and the output shaft of the servo motor 50 is fixedly connected to the top end of the rotating rod 5. The rotating rod 5 extends along the height direction of the wall 1. When the servo motor 50 rotates, it can effectively drive the rotating rod 5 to rotate;

[0040] Therefore, a first bevel gear 51 is further connected to one end of the lead screw 4 close to the rotating rod 5. A second bevel gear 52 meshing with the first bevel gear 51 is fixedly arranged on the rotating rod 5. A plurality of second bevel gears 52 are correspondingly connected to a plurality of lead screws 4 on the wall 1. A slider 40 is also threadedly connected to the lead screw 4. The cleaning brush 2 is rotatably connected to the slider 40. Thus, the cleaning brush 2 can be connected to the lead screw 4 through the slider 40 and can be in threaded cooperation with the lead screw 4;

[0041] In addition, in order to rotatably connect the cleaning brush 2 to the slider 40, a power member for driving the cleaning brush 2 to rotate is further arranged on the wall 1 near the slider 40. The power member includes a gear 41 rotatably connected to the slider 40 through a rotating shaft and a rack 42 connected to the wall 1 close to the lead screw 4. The gear 41 is connected to the side of the slider 40 close to the wall 1. The length extension direction of the rack 42 is the same as the length extension direction of the lead screw 4. The teeth of the gear 41 mesh with the rack 42, and the cleaning brush 2 is fixedly connected to the gear 41.

[0042] When cleaning the wall 1, by starting the servo motor 50, the rotating rod 5 can be driven to rotate. Subsequently, the second bevel gear 52 connected to the rotating rod 5 can rotate accordingly. At this time, the first bevel gear 51 rotates relatively under the action of meshing with the second bevel gear 52, and multiple first bevel gears 51 can drive the lead screw 4 on the wall 1 to rotate synchronously; thereby enabling the slider 40 connected to the lead screw 4 to move relatively. And the gear 41 rotates along the rack 42 under the action of meshing with the rack 42. When the slider 40 moves, the rotation of the slider 40 is restricted by the gear 41 and the rack 42, so that the slider 40 can only slide horizontally along the wall 1. The cleaning brush 2 can not only slide horizontally along the wall 1 following the slider 40, but also rotate following the gear 41. Effectively, the edge of the cleaning brush 2 slides and rotates along the wall 1, and the center of the cleaning brush 2 is fixedly connected to the axis of the gear 41, making the cleaning brush 2 more stable during rotation. The structure is simple and easy to implement, improving the cleaning effect of the cleaning brush 2 on the wall 1 and increasing the aesthetic degree of the wall 1.

[0043] Refer to Figure 3 , in this embodiment, further to avoid damage to the servo motor 50, the first bevel gear 51 and the second bevel gear 52 due to long-term exposure, protective covers 53 are provided on the servo motor 50, the first bevel gear 51 and the second bevel gear 52, and the protective covers 53 can be connected to the wall 1.

[0044] Refer to Figure 2 and Figure 3 , in this embodiment, further to effectively supply water to the spray head 3 by the water supply component. Therefore, the water supply component is arranged at the bottom of the planting tank 10, including a water storage tank 7. The water storage tank 7 is communicated with the planting tank 10, and the length extension direction of the water storage tank 7 is the same as that of the planting tank 10. A water delivery hose 6 is connected between the spray head 3 and the water storage tank 7, and one end of the water delivery hose 6 connected to the spray head 3 is fixedly connected to the slider 40. The spraying direction of the spray head 3 is directly opposite to the wall surface of the wall 1. One end of the water delivery hose 6 close to the water storage tank 7 is connected with a switch valve 60, and a controller 11 electrically connected to the switch valve 60 is provided on the wall 1;

[0045] Refer to Figure 3 and Figure 4, during the rainfall period, if there is a large amount of rainwater collected in the planting trough 10, the excess rainwater can be discharged from the bottom of the planting trough 10 into the water storage tank 7. In order to prevent the planting soil layer 101 in the planting trough 10 from flowing away, a geotextile 102 is laid at the bottom of the planting trough 10. The rainwater drained into the water storage tank 7 can be stored in the water storage tank 7. The controller 11 controls the opening of the on-off valve 60, and the accumulated water in the water storage tank 7 can be effectively supplied to the spray head 3 through the water delivery hose 6 to spray the wall surface. An overflow port 70 is also provided on the side wall of the water storage tank 7, and the excess rainwater in the water storage tank 7 can be discharged through the overflow port 70; and during the process of supplying water to the spray head 3 by the water delivery pipe, the spray head 3 can move along with the sliding of the slider 40, so that when the cleaning brush 2 cleans the wall 1, the wall 1 can be sprayed with water at any time, improving the cleaning effect of the wall 1.

[0046] Refer to Figure 3 , in this embodiment, if the water accumulated in the planting trough 10 and the water storage tank 7 cannot meet the usage requirements, in order to continuously supply water to the spray head 3, therefore, the provided water storage assembly includes a water storage tank 8. The water storage tank 8 is arranged on the top of the wall 1, and the water storage tank 8 is open at the top. A water supply pipe 80 is connected to the water storage tank 8, and the water supply pipe 80 is communicated with a plurality of water storage tanks 7. A control valve 81 is provided at one end of the water supply pipe 80 close to the water storage tank 8, and the control valve 81 is electrically connected to the controller 11;

[0047] The water storage tank 8 can store part of the rainwater during the rainfall period. In order to prevent garbage and leaves from falling into the water storage tank 8, a filter screen 82 is connected to the open mouth of the water storage tank 8. An overflow pipe 83 is also connected to the side wall of the water storage tank 8, and the excess water in the water storage tank 8 can be discharged through the overflow pipe 83; when the water accumulated in the water storage tank 7 does not meet the usage requirements, the controller 11 controls the control valve 81 to open, and the water supply pipe 80 transports the rainwater in the water storage tank 8 into the water storage tank 7 to timely supplement the water for spraying of the spray head 3. A plurality of absorbent cotton ropes 103 are connected between the planting trough 10 and the water storage tank 7, and the water can be transferred to the planting trough 10 through the absorbent cotton ropes 103 to maintain the water demand in the planting trough 10, so that the green plants in the planting trough 10 do not only rely on the rainfall period to supplement water, effectively improving the survival rate of the green plants. An inlet pipe 84 can also be connected to the water storage tank 8, and the inlet pipe 84 can be connected to the water supply network of the building to increase the water storage channels and ensure the water usage requirements even in the non-rainy period.

[0048] The implementation principle of a cleaning device for the wall 1 of a green building in an embodiment of the present application is as follows: When there is a lot of dirt adhering to the wall surface of the wall 1 between adjacent planting grooves 10 of the green building wall 1, which affects the aesthetics of the building, the servo motor 50 is started to drive the rotating rod 5 to rotate. Subsequently, the first bevel gear 51 and the second bevel gear 52 move relative to each other, and the second bevel gear 52 effectively drives the first bevel gear 51 to rotate. The lead screw 4 also rotates under the drive of the first bevel gear 51, so that the slider 40 on the lead screw 4 has a tendency to move, and drives the cleaning brush 2 to slide horizontally along the wall 1 under the restriction of the chute. At the same time, when the slider 40 slides, the gear 41 can rotate along the rack 42, so that the cleaning brush 2 can rotate while rotating along the wall 1, effectively increasing the cleaning effect on the wall 1. And when the cleaning brush 2 cleans the wall 1, the controller 11 can control the water supply hose 6 to open, and the water in the water storage tank 7 can be supplied to the spray head 3, so that the spray head 3 can spray water when the cleaning brush 2 cleans the wall 1, further improving the cleaning effect on the wall 1 and increasing the aesthetics of the wall 1.

[0049] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
