TECHNICAL FIELD

[0001] The present application belongs to the field of cleaning machines, and particularly relates to a cleaning machine for building outer walls or glass curtain walls. BACKGROUND

[0002] The appearance of high-rise buildings directly affects the beauty of a city. In order to keep high-rise buildings clean and beautiful, the owners need to hire professional cleaning companies to clean the outer walls or glass curtain walls, which costs a lot of money every year. At present, the outer walls of high-rise buildings at home and abroad are mostly cleaned by manual labor, that is, cleaning workers are hung by ropes to clean the walls by hand. This method not only has high labor intensity, low efficiency and high labor cost, but also is extremely unsafe, and personnel casualties are likely to occur in high-altitude operations. There have been reports in the media of accidents in which cleaning workers have fallen from high altitudes and died.

[0003] At present, there are some glass curtain wall cleaning machine products or designs, mainly full-automatic robot cleaning machines and semi-automatic (manual remote control) cleaning machines. The problems are: the full-automatic robot cleaning machine has high intelligence, but is expensive, has limited power supply and water supply capacity, and has slow crawling speed, which affects its continuous working capacity and efficiency, making it difficult to bear the cleaning of large-area outer walls of high-rise buildings; the existing semi-automatic (manual remote control) cleaning machine has complex structure, heavy weight, imperfect crawling and adsorption functions, and still has the disadvantages of high power consumption, slow working speed and low efficiency; at present, these two types of cleaning machines are not widely used and promoted in the market, except for a small amount of application of full-automatic robot cleaning machines, others are still in the design test stage.

[0004] The following problems still need to be solved urgently for the current glass curtain wall cleaning machine:

[0005] (1) lightness;

[0006] (2) fast crawling and fast cleaning ability;

[0007] (3) good wall adsorption ability;

[0008] (4) continuous water supply and high-efficiency cleaning ability;

[0009] (5) continuous power supply and large-area working ability.

[0010] Some product designs have good crawling and adsorption ability, but have complex structure, heavy weight, high power consumption, which directly affects the continuous power supply working ability and working efficiency. SUMMARY

[0020] Hanger is installed on both sides of box, and the roller A at the end of hanger is hung on guide rail A, can roll along guide rail A, and pulls main machine to wall surface, so that the part of brush roll and scraper protruding from box tightly adheres to wall surface.

[0021] Water jet pipe is horizontally installed near brush roll position and is communicated with water supply pipe, and water jet hole is arranged on water jet pipe.Valve is installed on water supply pipe, water supply end is connected with water source, and the valve can be electromagnetic valve or other electric valve.

[0022] The main controller is connected with the power supply by a wire, and is used for controlling the main machine to work, including controlling the motors, valves and other electrical devices on the main machine.

[0023] The lower end of the box body is provided with a water collecting pool, and the bottom of the box body is provided with a drain pipe.

[0024] During operation, the rope winding machine A is started to release the rope, the main machine is moved downward along the guide rail A from the top of the wall surface, water supply is opened, water is sprayed by the water spraying pipe, the brush roller is rotated by starting the motor B, the wall surface is washed, the water on the wall surface is scraped by the scraper, the washed sewage flows along the surface of the scraper below the brush roller to the water collecting pool at the lower end of the box body, and when the main machine moves to the bottom of the wall surface, the cleaning of the wall surface in the region between the two guide rails A is completed.

[0025] In the above technical solution:

[0026] A drying brush can be installed above the uppermost group of brush rollers and scrapers in the box body, contacts the wall surface, and is used for wiping the residual water on the cleaned wall surface. The drying brush can be a brush roller structure of water-absorbing cotton fabric or sponge material, or a strip-shaped block structure.

[0027] The above rope winding machine A can adopt an integrated structure provided with two winding reels, that is, the two winding reels winding two hanging ropes are installed on an axle, and one motor A is arranged to drive the axle and the two winding reels on the axle to rotate synchronously, or two motors A are arranged to control and drive the two winding reels to rotate respectively; or two separate split type rope winding machines A are arranged to control the winding and unwinding of the two hanging ropes.

[0028] The hanger installed on the two sides of the box body includes a support and a pull rod, the support is fixedly installed on the side surface of the box body, the pull rod is sleeved in the hole on the support and can slide in the hole, the end of the pull rod is provided with a roller A, the roller A is hung on the guide rail A, a spring is arranged between the pull rod and the support, and the pull rod pulls the main machine to the wall surface by overcoming the elastic force of the spring.

The cross section of the strip-shaped guide rail is in a concave groove structure, and the roller A at the end of the hanger is hung in the concave groove and can roll in the concave groove. In order not to affect the appearance of the outer wall, the strip-shaped guide rail can adopt transparent plastic material, or can be made of a material consistent with the color of the outer wall or paint. If the steel wire is used as the guide rail, the upper and lower ends of the steel wire are fixed on the wall surface, the steel wire is pulled tight, the steel wire is fixed on the wall surface at intervals by a clamping seat, and a groove is arranged on the circumferential surface of the roller A at the end of the hanger, and the hanger is hung on the steel wire through the groove.

[0030] The host water supply can be directly connected to a pressure water source such as tap water through a hose, so that the host can obtain continuous water supply. Another method is to provide a water tank on the host, and a water supply pipe is connected to the water tank, and a water pump and a valve are connected to the water supply pipe, and the water supply pipe is connected to the water spraying pipe in the host. The water pump provides water pressure during operation. The advantage is that the long water supply pipe and the drain pipe are omitted, which is beneficial to the appearance, but the weight and volume of the host are increased. When the water in the water tank is used up, the host can continue to work only after the water is added and the sewage is discharged.

[0031] The host power supply can be directly connected to a power source through a wire, so that the host can obtain continuous power supply. Another method is to provide a rechargeable battery on the host, and the battery supplies power to the host. The long wire can be omitted, which is beneficial to the appearance. The disadvantage is that the weight and volume of the host are increased. When the battery is used up, the host can continue to work only after being charged.

[0032] To realize the horizontal transverse movement of the host, a horizontal walking mechanism can be provided on the top of the wall. That is, a horizontal guide rail B is installed on the wall by a fixing frame. A hanging rod is provided on the rope winding machine A, and a roller B is provided on the upper end of the hanging rod. The roller B is hung on the horizontal guide rail B and can roll left and right. In this way, the rope winding machine A and the host are hung on the horizontal guide rail B. Rope winding machines B are provided on the left and right ends of the horizontal guide rail B. The structure of the rope winding machines B is the same as that of the aforementioned split type rope winding machine A. The ends of the pull ropes drawn by the left and right rope winding machines B are connected to the machine body of the rope winding machine A or the hanging rod. During operation, the rope winding machine A on the left or right side is started to wind the rope, which can pull the rope winding machine A and the host to move left or right along the horizontal guide rail B, realizing the horizontal walking of the cleaning machine.

[0033] To facilitate operation, a remote control device can be added. That is, a handheld remote controller is provided, a remote control receiver A is provided on the rope winding machine A, and a remote control receiver B is provided on the host. The operator controls the operation of the rope winding machine A and the host through the handheld remote controller. Similarly, a remote control receiver C can be provided on the rope winding machine B, and the operator controls the left and right walking of the cleaning machine through the handheld remote controller.

[0034] To enhance the cleaning effect, a cleaning agent adding device can be added. A cleaning agent container is provided on the host. The cleaning agent is added to the container and diluted with water. The diluted liquid is then introduced to the brush roller through a hose. Or a water tank is provided on the water source to directly add cleaning agent to the water source.

[0035] The above-mentioned drying brush, water tank, battery, horizontal walking mechanism, remote control device, and cleaning agent adding device can be selected and configured according to the site conditions of the wall and the actual needs of the user. Appropriate wall arrangement methods are selected. The cleaning machine configuration and arrangement method is more typical.

[0036] (1) Multiple cleaning machines arranged horizontally in parallel: For low-rise exterior walls or glass curtain walls with a height of 1 to 3 floors, there is a lot of dust at the lower floors and they need to maintain a clean appearance. They need to be cleaned multiple times a day or a week. Multiple cleaning machines can be arranged horizontally in parallel to cover the entire width of the wall. In this way, there is no need to configure a horizontal walking mechanism, and the entire wall can be cleaned in one operation, which is convenient for frequent cleaning.

[0037] Optional remote control device for easy operation.

[0038] Optional water tanks or batteries can save water pipes or wires, which helps to keep the exterior wall neat and beautiful.

[0039] (2) Arrangement of a single cleaning machine equipped with a horizontal travel mechanism: For medium and high-rise walls with a height of about 3 to 15 floors, the cleaning frequency is low, for example, only a few times per quarter or per year. A cleaning machine can be arranged on a single wall and equipped with a horizontal travel mechanism. The wall is divided into multiple vertical areas of equal width, such as a1, a2, a3, a4, etc. Each area is equipped with a vertical guide rail A, and a cleaning machine of the corresponding length is customized to cover the entire wall. Due to the high wall and large area, it is not suitable to configure a water tank or battery. A remote control device is optional.

[0040] During cleaning, operate the cleaning machine to clean area a1 first, then operate the horizontal travel mechanism to move the cleaning machine to area a2 for cleaning, and complete the cleaning of areas a3, a4, etc. in sequence.

[0041] (3) Arrange multiple cleaning machines in an array of wall sections: For large-area high-rise walls with a height of 10 to 30 floors or a wide width, the wall can be divided into multiple sections. Each section is equipped with a cleaning machine equipped with a horizontal walking mechanism, that is, the above-mentioned (2) configuration. Each cleaning machine is responsible for cleaning the wall of its own section.

[0042] In specific applications, it is not limited to the above three typical configurations and arrangements. For example, for a wall with a height of about 10 floors, the above configuration and arrangement method (1) or the above configuration and arrangement method (2) can be adopted.

[0043] Beneficial effects:

[0044] The present invention utilizes a unique electric rope suspension mechanism, a track-type automatic crawling mechanism, a continuous automatic water and power supply mechanism, a multi-stage flushing mechanism, an electric horizontal travel mechanism, and a remote control device, comprehensively resolving many of the problems existing in existing semi-automatic or fully automatic glass curtain wall cleaning machines. Compared with existing semi-automatic or fully automatic glass curtain wall cleaning machines, the present invention has the following advantages:

[0045] (1) Simple structure, small size, light weight, low manufacturing cost, low power consumption, low operation and maintenance cost;

[0046] (2) The wall surface guide rail type crawling structure has good rapid crawling and wall surface adsorption capacity, high running speed and high safety reliability;

[0047] (3) The multi-stage flushing structure can continuously supply water, has high cleaning capacity and high efficiency;

[0048] (4) It can continuously supply power and has large-area continuous working capacity;

[0049] (5) The horizontal walking mechanism and remote control device are provided, so that semi-automatic operation is realized, and operation is simple;

[0050] (6) The application range is wide, and the cleaning machine can be used for cleaning the wall surface or glass curtain wall of various low-rise and high-rise buildings;

[0051] (7) The cleaning machine has high practicability and can be actually applied.

[0052] The cleaning machine solves the problems that the existing semi-automatic (manual remote control) glass curtain wall cleaning machine has complex structure, heavy weight, imperfect crawling and adsorption functions, large power consumption, slow working speed, low efficiency and is difficult to be actually applied; and the existing fully automatic robot glass curtain wall cleaning machine has complex structure, heavy weight, high price, high running energy consumption, limited continuous power supply and water supply capacity, slow crawling speed, low continuous working capacity and efficiency, is difficult to clean large-area outer wall of high-rise buildings, and is difficult to be widely promoted, so the cleaning machine has good practicability and application prospect.

[0053] The cleaning machine can replace the current widely used manual high-altitude scrubbing operation (high labor intensity, low efficiency, high cost and poor safety), saves a large amount of cleaning cost for users, prevents personal safety risks caused by manual high-altitude operation, and has the advantages of high efficiency, energy saving and safety.

[0099] The reel machine A13 is selected as Figure 7 an integral structure, which is fixedly installed at the top of the wall, and the power supply of the motor A15 is directly connected to the power supply, so that sufficient power supply can be obtained.

[0100] Because the wall is not high, the water supply pipe 8 can be connected to the tap water from the top of the wall by using a quick connector, or the tap water can be connected from the ground.

[0101] As shown in Figure 19 , the water supply pipes of the cleaning machines C1, C2, C3, C4, etc. can be horizontally connected and then connected to the water source by a water supply pipe 8, and the wires of the cleaning machines can be horizontally connected and then connected to the power supply by a wire 9, and the drain pipes of the cleaning machines can be horizontally connected and then drained by a floor drain pipe 12.

[0102] The forced drainage device described in embodiment 1 can also be selected.

[0103] A remote control device can be selected for convenient operation.

[0104] The operation method of the above arrangement is as follows: first, connect the water supply pipe 8 to the water supply pipe connection interface, and connect the wire 9 and the drain pipe 12 to the respective connection interfaces, turn on the power switch and the water source valve, and then turn on the main control 10 switch and the reel machine A13 rope release switch, or control through the handheld remote control, the main machine 1 of the cleaning machines C1, C2, C3, C4, etc. automatically moves downward along the respective tracks A2 and brushes the wall from top to bottom, and then closes the main control 10 and the reel machine A13 to complete the cleaning of the entire wall. At this time, if necessary, only the main control 10 can be turned on for about one minute to clean the brush roller 4 in the main machine 1.

[0105] If the wall needs to be cleaned again, the reel machine A13 rope release switch (or operated through the remote control) is turned on, the main machine 1 is moved upward to the top of the wall, and the above cleaning operation is repeated.

[0106] After cleaning is completed, the main machine 1 is reset to the top of the wall, and the water supply pipe 8, the wire 9, and the drain pipe 12 (all three are main pipes) are pulled out and stacked in the warehouse or equipment room.

[0107] If there are more cleaning machines arranged horizontally, such as 12 cleaning machines, 4 adjacent cleaning machines can be grouped into 3 groups, and the water supply pipes, wires, and drain pipes of each group are connected, and each group can be operated separately during cleaning.

[0108] If the user needs, host 1 can be equipped with Figure 11 The water tank 23 and battery 19 shown eliminate the need for water supply pipe 8 and electrical wiring 9 connecting the main unit 1. The water tank 23 facilitates the addition of cleaning agents. In this case, the battery 19 only powers the low-power water pump 20, electric valve 7, and brush roller motor B4, resulting in low power consumption. This allows for a smaller battery 19, which, once fully charged, can handle multiple cleaning cycles. Aside from the need to charge the battery 19 and add water to the water tank 23 (which can be connected in parallel), the rest of the cleaning process is identical to the above-described one.

[0109] Example 3:

[0110] like Figure 20 The figure shows an example of a single cleaning machine equipped with a horizontal travel mechanism. This is suitable for walls 3 to 15 stories high and with low cleaning frequency. A single wall can be equipped with a cleaning machine C1 and a horizontal travel mechanism. The wall can be divided into multiple vertical zones of equal width, a1, a2, a3, a4, etc., each equipped with a vertical guide rail A2. Due to the high and large wall surface, a water tank or battery is not suitable. A remote control is optional.

[0111] During cleaning, the cleaning machine C1 is operated to clean area a1 first, and then the horizontal travel mechanism is operated to move the cleaning machine to clean area a2, and then to clean areas a3, a4, etc. As in Example 2, after cleaning, the connected water supply pipe 8, electrical wires 9, and drain pipe 12 are removed and stored for reconnection during the next cleaning.

[0112] When the cleaning machine C1 moves horizontally, the roller 27 at the end of the hanger 5 can be manually removed from the guide rail A2 and then connected to the guide rail A2 of the next area. Alternatively, a horizontal parallel rail can be set at the top or bottom of the wall to move the roller 27 along the horizontal rail to the guide rail A2 of the next area.

[0113] Example 4:

[0114] like Figure 21 The figure shows an application embodiment in which multiple cleaning machines are arranged in an array of partitioned walls. This embodiment is suitable for high-rise walls 10 to 30 stories high or wide. The wall can be divided into multiple partitions A1, A2, A3, A4, etc., each equipped with a cleaning machine C1, C2, C3, C4, etc. equipped with a horizontal travel mechanism. The cleaning machines are configured as in Example 3 above, with each cleaning machine responsible for cleaning its own partitioned wall surface. The operation method is the same as in Example 3.

[0115] In specific applications, the present application is not limited to the above four typical configurations and arrangements. For example, for a wall surface with a height of about 10 floors, the configuration and arrangement of Embodiment 3 can be used, or the configuration and arrangement of Embodiment 2 can be used, and a suitable scheme can be selected according to the site conditions and actual needs of the user.
