Description

Technical Field

[0001] This invention relates to the field of glass curtain wall cleaning technology, and more particularly to a self-cleaning device for the exterior of building glass in rainy weather. Background Technology

[0002] With economic development and increasingly modernized urbanization, glass curtain walls are commonly used in office buildings and high-rises. These exterior windows can effectively ensure the interior view.

[0003] However, cleaning a large number of exterior windows is also a very dangerous job. It usually involves using ropes in conjunction with manual cleaning, which is costly, dangerous, and affected by the weather. It cannot meet the higher actual cleaning needs, so there is a need for improvement. Summary of the Invention

[0004] This invention provides a self-cleaning device for the exterior of building windows in rainy weather that can utilize natural resources for cleaning, is energy-saving and environmentally friendly, reduces cleaning costs and risks, and provides excellent cleaning results, thus meeting higher cleaning requirements for exterior windows. It solves the technical problems of existing technologies where the cleaning of exterior windows of high-rise buildings mainly relies on manual labor, resulting in high cleaning costs, high risk factors, and high susceptibility to weather conditions, failing to meet the higher cleaning requirements for exterior windows.

[0005] The above-mentioned technical problem of the present invention is solved by the following technical solution: a self-cleaning device for the exterior of a house window in rainy weather, comprising an exterior wall, with a plurality of window panes spaced apart on the exterior wall, and a set of self-cleaning devices on the exterior wall on both sides of each window pane, the self-cleaning device comprising two water-storing cylinders installed on both sides of the window panes, with water entering from the top and exiting from the bottom of the water-storing cylinders; each water-storing cylinder contains a float that can float up and down, with an upwardly extending vertical rod fixed on the float, and a cleaning brush attached to the surface of the window pane between two adjacent vertical rods; a sealing component for controlling water flow is provided at the outlet at the bottom of the water-storing cylinder; when rainwater accumulates in the water-storing cylinder, the float drives the vertical rod and the cleaning brush to rise to achieve cleaning; when the float rises to a preset high point, it triggers the sealing component to open the drain outlet, the rainwater in the water-storing cylinder is quickly discharged, and the float drives the cleaning brush to descend; when the float descends to a preset low point, the sealing component resets and closes the drain outlet. This invention utilizes rainwater and a float to achieve mechanical reciprocating lifting and lowering, which drives the cleaning brush to reciprocate and lower to clean the window glass. It can clean multiple times and repeatedly during a single rainfall, improving the cleaning effect, eliminating the need for manual cleaning, reducing cleaning costs and cleaning safety hazards.

[0006] Preferably, the sealing assembly includes a float switch at the bottom of the water storage cylinder, with a pull rope connecting the float switch to the float cylinder; a ring-shaped magnetic block is located at the bottom of the float switch, and the magnetic block is attached to the inner wall surrounding the outlet at the bottom of the water storage cylinder. The float switch and the magnetic block ensure a seal on the outlet. When the float cylinder rises to the top, the pull rope pulls up and detaches the float switch and magnetic block at the bottom, opening the outlet and allowing rainwater to be transported to the next layer.

[0007] Preferably, the float switch has a hollow internal structure, and several through-holes are provided around its perimeter. The center of the float switch cooperates with a magnetic block to ensure a seal. The hollow structure of the float switch ensures its own buoyancy. After being pulled away from the bottom under the action of tension, the float switch can continue to float until it fits against the bottom of the float, and finally descends with the float. The surrounding water-permeable holes ensure that rainwater can drain downwards without affecting the seal and buoyancy of the float switch.

[0008] Preferably, a sealing ring is embedded on the sealing surface of the magnetic block and the water storage cylinder. The sealing ring is also embedded on the sealing surface at the bottom of the water storage cylinder, cooperating with the magnetic block to achieve a seal.

[0009] Preferably, the water storage cylinder is equipped with an inlet pipe at the top, and the inlet pipe of the lower water storage cylinder is connected to the outlet of the upper water storage cylinder. The inlet pipe of the top water storage cylinder is connected to the roof drain pipe. During rainy weather, rainwater enters the water storage cylinder from the roof drain pipe along the inlet pipe; rainwater can also flow down from the bottom outlet into the water storage cylinder of the next floor.

[0010] Preferably, two connecting pipes are installed between the two adjacent water storage cylinders. One connecting pipe connects the bottom of the two adjacent water storage cylinders, and the other connecting pipe connects the outlets of the two adjacent water storage cylinders, ensuring synchronous water inflow and outflow. A cap is installed at the outlet of the water storage cylinder not connected to the inflow pipe. During rainy weather, rainwater enters the water storage cylinder from the roof drain pipe along the inflow pipe, and simultaneously flows into the water storage cylinder on the other side through the connecting pipe. As the amount of rainwater in the two water storage cylinders increases, the two floats rise slowly and synchronously, driving the cleaning brushes upwards to perform the first cleaning of the window glass in conjunction with the rainwater. When the magnetic block detaches, the rainwater in the two water storage cylinders is simultaneously discharged from the bottom outlet due to the connection effect of the connecting pipe, flowing along the inflow pipe to the water storage cylinder on the next floor. As the rainwater is discharged, the floats descend as a whole.

[0011] Preferably, the water storage cylinder has a split structure, with sealing caps at both the top and bottom. The top sealing cap has mounting holes corresponding to the vertical rod and the water inlet pipe, while the bottom sealing cap has a water outlet. The bottom sealing cap is made of metal or has embedded magnetic metal parts for use with a magnetic block. The split design of the water storage cylinder facilitates assembly and adjustment.

[0012] As a preferred embodiment, during rainy days, rainwater enters the water storage cylinder through the eaves drain pipe and inlet pipe, and simultaneously enters the other water storage cylinder through the connecting pipe. As the amount of rainwater in the two water storage cylinders increases, the two floats rise slowly and synchronously, driving the cleaning brush to move upward, which, together with the rainwater, can clean the window glass.

[0013] Preferably, when the float rises to the top, the bottom float switch and magnetic block are pulled up and detached by the pull rope. The float switch continues to float upward under its own buoyancy. After the magnetic block is detached, rainwater is discharged from the bottom outlet into the water storage cylinder on the next floor. As the rainwater is discharged, the float descends as a whole, and the cleaning brush descends simultaneously to clean the window glass. When the rainwater is completely drained, the magnetic block seals the outlet under the action of magnetism. The above steps are repeated continuously, so that the cleaning brush cleans the window glass repeatedly until the rain stops.

[0014] Therefore, the self-cleaning device for the exterior of house windows in rainy weather according to the present invention has the following advantages: it can use natural resources to clean the exterior windows, is energy-saving and environmentally friendly, can reduce cleaning costs and cleaning risks, and has excellent cleaning effect, which can meet the higher cleaning requirements of exterior windows.

Detailed Implementation

[0022] The technical solution of the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: like Figure 1 and 2 As shown in Figures 3, 4, 5, and 6, a self-cleaning device for the exterior of a building glass in rainy weather includes an exterior wall 1, on which a number of window glass panes 2 are installed at intervals. A set of self-cleaning devices is installed on the exterior wall 1 on both sides of each window glass pane 2. The self-cleaning device includes two water storage cylinders 3 installed on both sides of the window glass pane 2.

[0024] The water storage cylinder 3 has a top inlet and a bottom outlet. The water storage cylinder 3 has a split structure. The top and bottom ends of the water storage cylinder 3 are equipped with sealing caps 4. The top sealing cap 4 has two installation holes, and the bottom sealing cap 4 has one water outlet 5.

[0025] A water inlet pipe 6 is installed on the top of one of the water storage cylinders 3, and the water inlet pipe 6 of the lower water storage cylinder 3 is connected to the water outlet 5 of the upper water storage cylinder 3.

[0026] Two connecting pipes 7 are provided between the left and right adjacent water storage cylinders 3; one connecting pipe 7 connects the bottom of the cavity of the left and right adjacent water storage cylinders 3, and the other connecting pipe 7 connects the outlet 5 of the left and right adjacent water storage cylinders 3, forming a flow loop.

[0027] A cap 8 is provided at the outlet 5 of the water storage cylinder 3 that is not connected to the water inlet pipe 6, so that the water inlet and outlet of the water storage cylinder 3 in the same group are carried out simultaneously.

[0028] Each water storage cylinder 3 is equipped with a float 9 that can float up and down. A vertical rod 10 is installed on the float 9. The vertical rod 10 extends upward through the mounting hole. Two adjacent vertical rods 10 on the left and right are directly fitted with cleaning brushes 11 that are attached to the surface of the window glass 2.

[0029] The cleaning brush 11 is a cleaning structure consisting of a silicone scraper or silicone brush, an absorbent sponge, etc.

[0030] A sealing component for controlling water flow is installed at the water outlet 5 at the bottom of the water storage cylinder 3. The sealing component includes a float switch 12 installed at the water outlet 5 at the bottom of the water storage cylinder 3. The float switch 12 has an internal hollow structure, and several through-holes 13 are spaced apart on the periphery of the float switch 12.

[0031] A pull rope 15 is installed between the float switch 12 and the float 9; a ring-shaped magnetic block 14 is fixedly installed at the bottom of the float switch 12, and the magnetic block 14 is attracted to the inner wall of the outlet 5. The middle part of the float switch 12 cooperates with the magnetic block 14 to ensure a seal.

[0032] A sealing ring 16 is embedded in the sealing surface between the magnetic block 14 and the water storage tank.

[0033] The inlet pipe 6 of the top water storage cylinder 3 is connected to the drain pipe on the roof. During rainy weather, rainwater enters the water storage cylinder 3 from the drain pipe on the roof along the inlet pipe 6. The rainwater also enters the water storage cylinder 3 on the other side through the connecting pipe. As the amount of rainwater in the two water storage cylinders 3 increases, the two floats 9 rise slowly and synchronously, driving the cleaning brush 11 to move upward. With the help of the rainwater, the window glass 2 can be cleaned for the first time.

[0034] When the float 9 rises to the top, the bottom float switch 12 and magnetic block 14 are pulled up and detached by the pull rope 15. The float switch 12 continues to float up under its own buoyancy until it is in contact with the bottom surface of the float 9.

[0035] After the magnetic block 14 is released, rainwater is discharged from the outlet 5 at the bottom and flows along the inlet pipe 6 to the water storage cylinder 3 on the next floor. As the rainwater is discharged, the float 9 descends as a whole, and the cleaning brush 11 descends simultaneously to clean the window glass 2 for the second time.

[0036] When the rainwater is completely drained, the magnetic block 14 seals the outlet 5 under the action of magnetism, continuously repeating the above steps, so that the cleaning brush 11 cleans the window glass 2 repeatedly until the rain stops.

[0037] The specific embodiments described herein are merely illustrative of the concept of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
