The accompanying drawings are used to describe the embodiments of the present disclosure for illustrative purposes only. Those skilled in the art will easily recognize from the following description that, without departing from the principles of the present disclosure, alternative embodiments of the structures and methods shown in the present invention can be adopted.

[0039] An energy-saving building glass curtain wall intelligent cleaning device according to an embodiment of the present invention is as follows: Figure 1-2As shown, the device includes a support platform 6, a guide mechanism 3, a suspension mechanism, a cleaning unit 9, an adjustment mechanism and a control unit; wherein,

[0040] The support platform 6 is provided with a water supply mechanism 7 and a sewage collection mechanism 8. The water supply mechanism 7 includes a water supply pump, a water supply pipe and a water supply tank, and the sewage collection mechanism 8 includes a water collection tank 81 and a water storage tank 83. The support platform 6 can be a box structure or a frame structure, which is not specifically limited here. The main function of the support platform 6 is to fix and install other parts of the device. Rollers can be set at the bottom of the support platform 6 for easy dragging.

[0041] The guide mechanism 3 is arranged on the support platform 6 and faces the glass curtain wall 1. The guide mechanism 3 is connected to the vertical track 2 arranged on the outside of the glass curtain wall 1 and slides along the vertical track 2. Through the cooperation of the guide mechanism 3 and the vertical track, the displacement of the support platform 6 in a direction perpendicular to the glass curtain wall 1 can be limited, and the displacement of the support platform 6 in a lateral direction can also be limited. The lateral direction is a direction perpendicular to the vertical track 2 and parallel to the glass curtain wall 1.

[0042] The suspension mechanism includes a hoist 4 and a sling 5. The hoist 4 is arranged on the top of the building. The hoist 4 and the supporting platform 6 are connected through the sling 5, and the supporting platform 6 is driven by the hoist 4 to move up and down along the vertical track 2. Relying on the suspension mechanism and the device's own gravity, the cleaning unit 9 is driven to complete the scraping action on the surface of the glass curtain wall 1 while moving downward, thereby cleaning the glass curtain wall 1. The hoist 4 is the main energy-consuming component of the device.

[0043] The cleaning unit 9 is used to clean the glass curtain wall 1. The cleaning unit 9 includes a wetting mechanism, a wiping mechanism and a pressure sensor. The wetting mechanism and the wiping mechanism are both arranged toward the glass curtain wall 1. The wetting mechanism is located below the wiping mechanism. When the cleaning unit 9 moves downward, the cleaning steps of wetting first and then wiping are implemented; the pressure sensor is used to collect the pressure value between the cleaning unit 9 and the glass curtain wall 1, and the pressure value collected by the pressure sensor is compared with the preset pressure value to ensure the fit between the cleaning unit 9 and the glass curtain wall 1, thereby ensuring the cleaning effect; the wetting mechanism is connected to the water supply tank through a water supply pipe, and the water collection tank 81 is arranged below the cleaning mechanism to collect sewage flowing down from above.

[0044] The adjustment mechanism is fixed on the support platform 6 and connected to the cleaning mechanism. The adjustment mechanism is used to adjust the position of the cleaning structure so that the cleaning unit 9 is close to or away from the glass curtain wall 1. When cleaning the glass curtain wall 1, the position of the cleaning mechanism will be adjusted according to the size and position of the grid of the glass curtain wall 1. The adjustment mechanism can, for example, use multiple sets of electric push rods to achieve position adjustment in multiple directions. The control unit compares the pressure value collected by the pressure sensor with the preset pressure value. If the collected pressure value is equal to the preset pressure value, the control unit stops working so that the cleaning unit 9 is firmly attached to the surface of the glass curtain wall 1.

[0045] The control unit controls the suspension mechanism to drive the support platform 6 to move up and down along the vertical track 2, controls the adjustment mechanism to adjust the cleaning unit 9 to be close to or away from the glass curtain wall 1, and controls the water supply pump to supply water to the wetting mechanism. The control unit sequentially controls the adjustment mechanism to adjust the cleaning unit 9 to be close to the glass curtain wall 1, controls the water supply pump to start working to wet the glass curtain wall 1, controls the hoist 4 to work to make the support platform 6 move downward, drives the cleaning unit 9 to move downward, and completes a cleaning action. When repeated cleaning actions are required, the control unit can control the hoist 4 to pull the sling 5 upward and then downward, or control the adjustment mechanism to adjust the position of the cleaning unit 9 to complete repeated cleaning actions.

[0046] By wetting and wiping the glass curtain wall to simulate manual cleaning actions, the automatic cleaning of the glass curtain wall is achieved. The intelligent cleaning device replaces manual operations, reduces the labor intensity of workers, and eliminates safety hazards. The intelligent cleaning device of the embodiment of the present invention has simple operating conditions and low costs while meeting high cleanliness requirements. The manual cleaning action is mechanized and automated to form a stable, reliable and energy-efficient intelligent cleaning device for glass curtain walls, with fewer energy-consuming parts, low energy consumption, energy saving and environmental protection; and the device is novel in conception, ingenious in structure, and has strong practicality and economic value.

[0047] In an optional embodiment, the guide mechanism 3 can be provided in one or more groups; if there is one group of guide mechanisms 3, the guide mechanism 3 is provided in the middle of the device, and the cleaning unit 9 can be provided along both sides of the guide mechanism 3; if there are two groups of guide mechanisms 3, such as Figure 3 As shown, two groups of guide mechanisms 3 are respectively arranged on both sides of the device, and the cleaning unit 9 is arranged between the two groups of guide mechanisms 3, and multiple cleaning units 9 are arranged between the two groups of guide mechanisms 3 to increase the width of one cleaning and improve the cleaning efficiency. The guide mechanism 3, for example, includes a guide wheel and a support rod, one end of the support rod is fixed on the support platform 6, and the other end is fixed to the guide wheel, and the guide wheel is limited in the vertical track 2. The support rod is a telescopic rod with adjustable length, and the distance between the glass curtain wall 1 and the support platform 6 can be adjusted according to different working conditions. The setting method of the guide mechanism 3 includes but is not limited to the above method.

[0048] An optional implementation method, such as Figure 2 As shown, the wetting mechanism includes a wetting roller 93, a roller bracket and a spray head. The roller bracket is an elastic bracket. The elastic bracket allows elastic force between the wetting roller 93 and the glass curtain wall 1 to ensure that the wetting roller 93 is firmly attached to the glass curtain wall 1. The rotational power of the wetting roller 93 comes from the conversion of the gravitational potential energy of the device without the need for an additional power supply. The width of the wetting roller 93 is matched with the width of the wiper mechanism, and the two widths are usually the same. The elastic bracket, for example, adopts a spring combined with a support rod structure. The spray head is connected to a water supply pipeline, and the number of the spray heads is multiple, and multiple spray heads are arranged around the wetting roller 93. The surface of the wetting roller 93 is made of flexible material, such as sponge, non-woven fabric, cotton cloth or plastic material, etc. The specific material used is not specifically limited here. The wetting roller 93 is replaceable, and the flexible wetting roller 93 can better fit the surface of the glass curtain wall 1. The water spraying direction of the nozzle is toward the glass curtain wall 1. Optionally, the water spraying direction of the nozzle has an angle less than 90° with the glass curtain wall 1. The nozzle can be a nozzle with adjustable water spraying volume. A small battery or solar cell can also be used to provide power for the water supply pump.

[0049] In an optional embodiment, multiple nozzles are arranged on the upper and lower sides of the wetting roller 93, that is, a row of nozzles is arranged on the upper side of the wetting roller 93, and a row of nozzles is arranged on the lower side of the wetting roller 93. The upper and lower rows of nozzles can use the same type of nozzles or nozzles of different types. The lower row of nozzles is mainly used to spray water on the glass curtain wall to be cleaned to moisten the surface of the glass curtain wall 1, and the upper row of nozzles is mainly used to moisten the wetting roller 93 and rinse the glass curtain wall 1 after wiping. Optionally, the nozzles include an atomized water nozzle 95 and a high-pressure water nozzle 94. The atomized water nozzle 95 is arranged on the lower side of the wetting roller 93 and faces the glass curtain wall 1. The atomized water nozzle 95 has a large water spraying area and quickly wets the surface of the glass curtain wall 1; the high-pressure water nozzle 94 is arranged on the upper side of the wetting roller 93. The water spraying pressure of the high-pressure water nozzle 94 is relatively large. The water spraying angle of the high-pressure water nozzle can be adjusted to different angles according to needs. On the one hand, the high-pressure water nozzle 94 can rinse the glass curtain wall after the wetting roller is wetted and wiped. On the other hand, the high-pressure water nozzle 94 can rinse the wetting roller 93 to keep the wetting roller 93 clean and moist. The angle between the water spraying direction of the high-pressure water nozzle 94 and the glass curtain wall 1 is an acute angle, that is, there is an oblique downward flushing force, and the flushing effect is better.

[0050] In an optional embodiment, the wiper mechanism includes one or more wiper units 92, and the wiper unit 92 includes multiple wiper blades and a pressure adjustment mechanism 91. The multiple wiper blades are arranged side by side, and the width of the wiper blades matches the width of the glass curtain wall. The pressure adjustment mechanism 91 is used to adjust the pressure value between the wiper blade and the glass curtain wall 1, so that the wiper blade and the glass curtain wall 1 are firmly attached to each other to ensure the wiping effect. The pressure adjustment mechanism 91 adopts a spring structure, for example, and the spring is arranged at a fixed position of the wiper blade. The width of the wiper blade matches the distance between two adjacent vertical rails 2; the distance between two adjacent vertical rails 2 is generally the size of the glass curtain wall grid. As a cleaning cell, the width of the wiper blade matches the width of the cleaning cell, and the width of the wiper blade is equivalent to the width of the wet roller 93. The entire cleaning unit 9 can clean one cleaning cell when it runs downward once. If the width of the glass curtain wall grid is wide, multiple wiper mechanisms can be arranged side by side to increase the width of one cleaning.

[0051] If the wiping mechanism includes multiple wiping units 92, the total width of the multiple wiping units 92 matches the distance between two adjacent vertical tracks 2, or multiple wiping units 92 are set according to the width of the glass curtain wall grid, and the multiple wiping units 92 are arranged side by side in the horizontal direction (i.e., the width direction of the glass curtain wall) and staggered and overlapped in the vertical direction (the direction in which the vertical tracks extend), ensuring that the wiping width of the multiple wiping units 92 can cover the cleaning cells once, there is overlap between two adjacent wiping units 92, and there is no omission when the wiping unit moves downward to wipe, thereby ensuring the wiping and cleaning effect.

[0052] Optionally, one wiper unit 92 includes 2-5 wiper blades, preferably one wiper unit 92 has 4 wiper blades, such as Figure 3 As shown, four wipers are arranged vertically side by side, and one cleaning action is repeated four times to ensure that the surface of the glass curtain wall to be cleaned is not missed. The wiper is preferably made of rubber or silicone.

[0053] In an optional embodiment, the adjustment mechanism includes a vertical adjustment mechanism 11 and a vertical adjustment mechanism 12. One end of the vertical adjustment mechanism 11 is fixedly connected to the support platform 6, and the other end of the vertical adjustment mechanism 11 is connected to the vertical adjustment mechanism 12. The vertical adjustment mechanism 12 is also connected to the cleaning unit 9. The vertical adjustment mechanism 11 is used to adjust the vertical movement of the cleaning unit 9, and the vertical adjustment mechanism 12 is used to adjust the cleaning unit 9 to be close to or away from the glass curtain wall 1. Both the vertical adjustment mechanism 11 and the vertical adjustment mechanism 12 can use an electric telescopic rod or a hydraulic rod. The control unit controls the extension and contraction of the lateral telescopic rod so that the wetting mechanism and the wiper mechanism are close to or away from the glass curtain wall 1. The wetting mechanism and the wiper mechanism can use a vertical adjustment mechanism 12 to adjust the movement of the wetting mechanism and the wiper mechanism at the same time, or different vertical adjustment mechanisms 12 can be used to adjust the movement of the wetting mechanism and the wiper mechanism respectively. When a cleaning action is completed, the control unit controls the vertical adjustment mechanism 12 to retract (away from the glass curtain wall 1), and the wiper leaves the surface of the glass curtain wall 1. When reaching the next cleaning cell, the control unit controls the vertical adjustment mechanism 12 to extend, and the wiper blade at the front end of the wiper mechanism is close to the glass curtain wall 1. When the pressure value collected by the pressure sensor is equal to the preset pressure value, the vertical adjustment mechanism 12 stops moving.

[0054] The vertical adjustment mechanism 11 adjusts the movement of the cleaning unit 9 in the vertical direction. For example, when a small range of the glass curtain wall 1 needs to be repeatedly cleaned, the control unit controls the vertical adjustment mechanism 11 to extend and retract, and at the same time cooperates with the vertical adjustment mechanism 12 to move away from and close to the glass curtain wall 1, so as to complete the repeated scraping of the glass curtain wall 1 in a small range from top to bottom. The adjustment mechanism can be powered by a battery or a solar cell. Through the linkage control of each adjustment mechanism, the position of the cleaning unit 9 can be flexibly adjusted to achieve different cleaning purposes.

[0055] In an optional embodiment, the adjustment mechanism includes a vertical adjustment mechanism 11, a vertical adjustment mechanism 12 and an amplitude adjustment mechanism 13. The vertical adjustment mechanism 11 is used to adjust the vertical movement of the cleaning unit 9, and the vertical adjustment mechanism 12 is used to adjust the cleaning unit 9 to be close to or away from the glass curtain wall 1; the amplitude adjustment mechanism 13 is used to adjust the single cleaning width of the wiper mechanism. The vertical adjustment mechanism 11, the vertical adjustment mechanism 12 and the amplitude adjustment mechanism 13 can all use electric telescopic rods or hydraulic rods. The amplitude adjustment mechanism 13 can be arranged between the vertical adjustment mechanism 12 and the cleaning unit 9, or between the vertical adjustment mechanism 12 and the vertical adjustment mechanism 11, or between the vertical adjustment mechanism 11 and the supporting platform 6. If the wiper mechanism includes multiple wiper units 92, different wiper units 92 need to adjust their positions separately, and different wiper units 92 are connected to different adjustment mechanisms. The adjustment structure can adjust the wiper unit 92 to move in the vertical direction, close to or away from the glass curtain wall 1, or move along the width direction of the wiper unit 92. The positions of the plurality of wiper units 92 are adjusted by the amplitude adjustment mechanism 13 so that the width of the plurality of wiper units 92 can cover the width of a cleaning cell at a time. Figure 3 As shown, the two wiper units 92 are arranged diagonally. After cleaning once, the upper and lower positions of the two wiper units 92 are adjusted to clean again, completely covering all corners of the cleaning cells once, thereby ensuring the cleaning effect of the glass curtain wall.

[0056] In an optional embodiment, the sewage collection mechanism 8 also includes a close mechanism 82, which is used to adjust the distance between the water collection tank 81 and the glass curtain wall 1 so that the upper edge of the water collection tank 81 is close to the glass curtain wall 1. The water collection tank 81 is movably connected to the water reservoir 83 or the support platform 6, and the close mechanism 82 is arranged between the water collection tank 81 and the water reservoir 83 / support platform 6. The close mechanism 82 adopts, for example, an electric telescopic rod or a spring. The position of the water collection tank 81 relative to the glass curtain wall 1 is adjusted by the close mechanism 82 so that the front end of the water collection tank 81 is close to the surface of the glass curtain wall 1. A spring is preferably used, which has a simple structure and does not require redundant control programs. The front end of the water collection tank 81 is preferably made of silicone material to ensure the fit between the two and prevent water from floating.

[0057] An optional implementation manner, the energy-saving building glass curtain wall intelligent cleaning device described in the embodiment also includes a filtering mechanism 10, which is used to filter the sewage collected by the sewage collection mechanism 8 and store the filtered water into a water supply tank; the filtering mechanism 10 includes a filter box, a filter plate and a water storage tank; the bottom of the filter box is a gradient structure, and the sewage flows from the top to the bottom of the gradient structure, and the layer-by-layer filtration is automatically completed by the gravity of the water. The inner wall of the filter box is provided with a filter plate mounting groove, and the filter plate is installed in the filter plate mounting groove. The filter box includes a water inlet and a water outlet, the water inlet is connected to the water reservoir 83, and the water outlet is connected to the water storage tank. The sewage in the water reservoir 83 flows through the water inlet, the filter plate and the water outlet in turn into the water storage tank, and the water storage tank and the water supply tank are connected by a connecting pipe. The sewage is recycled by the filtering mechanism 10. After entering the water reservoir 83, the sewage is first precipitated and then filtered through the filter plate and stored in the water tank. When the water in the water supply tank is insufficient, the water in the water storage tank can be pumped into the water supply tank as a supplement. The water pump can be powered by a small battery or a solar cell.

[0058] In an optional embodiment, there are multiple filter plates, including at least a primary filter plate and a secondary filter plate. The sewage from the water reservoir 83 flows through the primary filter plate and the secondary filter plate in turn for filtration. After two filtrations, the cleanliness of the water can be ensured. Optionally, the primary filter plate is a sand filter plate to filter larger impurities; the secondary filter plate is an activated carbon filter plate to filter smaller impurities. It is understandable that three or more filter plates can be selected, and the same type or different types of filter plates can be selected, as long as sewage filtration can be achieved and the use standard is met.

[0059] In an optional implementation, the energy-saving building glass curtain wall intelligent cleaning device described in the embodiment further includes a monitoring unit, which includes a monitoring camera, a liquid level sensor and a monitor; the monitoring camera is arranged on the supporting platform 6, and is used to capture the image of the cleaned glass curtain wall 1 and the position image of the cleaning unit 9, and sends the captured image to the monitor for analysis; the liquid level sensor is arranged in the water supply tank, and is used to monitor the real-time liquid level value in the water supply tank, and sends the monitored liquid level value to the monitor. The monitoring data transmission can be wired or wireless, preferably wireless.

[0060] The monitor performs image analysis by monitoring the image of the cleaned glass curtain wall taken by the monitoring camera. If stains are identified, the monitor sends a control instruction to the control unit to perform repeated cleaning actions. This repeated cleaning action can achieve repeated cleaning in a small range by controlling the vertical adjustment mechanism 11. The monitor identifies whether the cleaning width of the cleaning unit 9 covers the width of the glass curtain wall 1 between the adjacent vertical tracks 2 by monitoring the position image of the cleaning unit 9 taken by the camera. If it is identified that the cleaning unit 9 does not cover the width of the glass curtain wall 1 between the adjacent vertical tracks 2, a control instruction is sent to control the adjustment mechanism through the control unit to adjust; usually when there is only one cleaning unit 9, the width of the wiper blade matches the width of the cleaning cell at one time, and no width adjustment is required. However, when there are multiple cleaning units 9, the width of the wiper blades of all cleaning units 9 needs to be greater than the width of the cleaning cell at one time to ensure that the cleaning cell is fully covered at one time, so the control unit needs to control the adjustment mechanism for adjustment, and the adjustment here can be adjusted by controlling the width of the amplitude adjustment mechanism 13. The cleaning process is monitored in real time by the monitoring unit to avoid the problem of inadequate cleaning, thereby avoiding rework. It is understandable that the image recognition program can use existing edge recognition algorithms to recognize the outline of the stain, the outline of the cleaning unit and the outline of the glass curtain wall, and perform analysis based on the recognized image.

[0061] In an optional embodiment, the monitoring unit also includes a remote monitoring terminal and an alarm; when the monitor detects that the liquid level in the water supply tank is lower than a preset value, an alarm signal is sent through the alarm to remind the staff to replenish water in time or complete automatic water supply. When the monitor recognizes that there are still stains on the glass curtain wall 1 after cleaning, an alarm signal is sent through the alarm, and an abnormal image is displayed through the remote monitoring terminal; for example, if there is a difference in brightness in the image, it can be determined that there are stains, and the staff can also manually judge whether there are stains based on the abnormal image. When the monitor recognizes that the cleaning unit 9 does not cover the width of the glass curtain wall 1 between adjacent vertical tracks 2, an alarm signal is sent through the alarm, and an abnormal image is displayed through the remote monitoring terminal; if there is a gap in the horizontal projection between two adjacent cleaning units 9, or there is a gap in the horizontal projection between the cleaning unit 9 and the edge of the first cleaning unit of the glass curtain wall, it can be determined that the cleaning unit 9 does not cover the glass curtain wall 1, and the staff can also make a manual judgment based on the abnormal image.

[0062] The remote monitoring terminal also includes a human-computer interaction interface, which displays abnormal images and manually sends control commands to achieve semi-supervisory operation and improve efficiency.
