Description

Technical Field

[0001] This utility model relates to the field of drone cleaning technology, and more specifically to a cleaning fluid supply device for curtain wall cleaning drones. Background Technology

[0002] Traditional glass exterior wall cleaning methods usually require manual operation, which is not only time-consuming and labor-intensive but also inefficient. However, using drones for cleaning can greatly improve cleaning efficiency. Drones can cover a larger area in a short time, and due to their precise control and stable flight performance, they can ensure consistent cleaning results.

[0003] Typically, drone cleaning of glass facades requires non-contact high-pressure cleaning equipment, such as a water tank equipped with a high-pressure water pump. High-pressure water is used to wash away dirt and dust from the glass facade surface. In addition, appropriate cleaning fluid and nozzles are also required to ensure cleaning effectiveness.

[0004] The water tanks currently configured typically contain a fixed ratio of cleaning fluid. However, the amount of dirt on the glass exterior varies. For areas with more dirt, the cleaning effect can only be ensured by increasing the rinsing time, which wastes the cleaning fluid and obviously does not improve the drone's flight time. Utility Model Content

[0010] The barrel has an internal partition that creates two independent spaces: a first space for holding a cleaning solution of a first concentration and a second space for holding a cleaning solution of a second concentration. A three-way valve is connected to the partition. The first inlet of the three-way valve is connected to the first space, the second inlet is connected to the second space, and the outlet is connected to the inlet of the water pump.

In the drawings, each identical or nearly identical component shown in the various figures may be denoted by the same reference numeral. For clarity, not every component is labeled in each figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:

[0021] Figure 1This is a schematic diagram of the cleaning fluid supply device for curtain wall cleaning drones shown in this utility model;

[0022] Figure 2 This is a schematic diagram of the internal structure of the barrel shown in this utility model. Detailed Implementation

[0023] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0024] Combination Figure 1 and Figure 2 As shown, this utility model proposes a cleaning fluid supply device for curtain wall cleaning drones, including a support frame 10, a barrel 20, a cover 30 and a water pump 40. The support frame 10 includes a base and multiple limiting rods connected to the base, forming a limiting space between the multiple limiting rods. The barrel 20 is set in the limiting space, and the cover 30 is detachably connected to the top of the support frame 10.

[0025] Before the cover 30 is installed in the limiting space, the upper part of the limiting space is in an open state, and the barrel 20 can be placed into the limiting space from the upper part of the limiting space. When the cover 30 is installed above the support frame 10, the limiting space is closed, and the barrel 20 is constrained within the limiting space.

[0026] In an optional embodiment, a plurality of rotatable threaded connectors 32 are provided below the cover 30, and a screw hole 11 is provided at the top of the limiting rod, with the threaded connectors 32 threadedly connected to the screw hole 11.

[0027] The threaded connector 32 includes a nut and a screw that are fixed to each other. The nut is rotatably connected to the bottom of the cover 30. By rotating the nut, the screw is connected to the screw hole 11, thus completing the fixation of the cover 30 and the support frame 10.

[0028] The cover 30 can be quickly attached to the drone, allowing the drone to quickly replace the barrel 20 and the battery.

[0029] Furthermore, the cover 30 is provided with multiple connecting seats 31 on its upper part. The connecting seats 31 are provided with insertion holes, which can be connected to the pin structure under the drone to achieve quick assembly.

[0030] Furthermore, the water pump 40 is connected to the side wall of the tank 20, and the tank 20 is provided with a partition 21, so that a first space 201 and a second space 202 are formed inside the tank 20. The first space 201 is used to contain a first concentration of cleaning liquid, and the second space 202 is used to contain a second concentration of cleaning liquid.

[0031] By setting two concentrations of cleaning solution, the concentration of the sprayed cleaning solution can be changed by extracting the first concentration of cleaning solution from the first space 201 or the second concentration of cleaning solution from the second space 202. Therefore, different concentrations of cleaning solution can be used flexibly to clean different curtain walls to achieve better cleaning results.

[0032] The top of the barrel 20 is provided with a first cover 23 and a second cover 24. The first cover 23 is used to close the first space 201, and the second cover 24 is used to close the second space 202.

[0033] A predetermined concentration of cleaning solution can be added to the first space 201 and the second space 202 after the first cover 23 and the second cover 24 are opened.

[0034] Preferably, the top of the barrel 20 is also provided with a handle, which is located between the first cover 23 and the second cover 24. This makes it easier for the user to pull the barrel 20 out of the limiting space.

[0035] Specifically, a three-way valve 22 is connected to the partition 21. The first inlet end of the three-way valve 22 is connected to the first space 201, the second inlet end of the three-way valve 22 is connected to the second space 202, and the outlet end of the three-way valve 22 is connected to the inlet end of the water pump 40. The three-way valve 22 is used to control the connection status between the first inlet end or the second inlet end and the inlet end of the water pump 40.

[0036] In a specific embodiment, the first concentration is less than the second concentration. Video data of the area to be cleaned is acquired by a drone to evaluate the degree of staining in the current area. Depending on the degree of staining, the cleaning agent is selected to be drawn from the first or second inlet. When the staining degree is high, the second inlet is opened and the first inlet is closed, and the cleaning liquid of the second concentration is drawn. When the staining degree is low, the first inlet is opened and the second inlet is closed, and the cleaning liquid of the first concentration is drawn, so as to achieve a better stain removal effect.

[0037] In an optional embodiment, a three-way valve 22 is disposed at the lower part of the barrel 20. The first liquid inlet end of the three-way valve 22 is connected to the first liquid inlet pipe 221, and the second liquid inlet end of the three-way valve 22 is connected to the second liquid inlet pipe 222. The first liquid inlet pipe 221 extends to the bottom of the first space 201, and the second liquid inlet pipe 222 is connected to the bottom of the second space 202.

[0038] Furthermore, the first liquid inlet pipe 221 and the second liquid inlet pipe 222 are preferably flexible hoses, and the ends of the first liquid inlet pipe 221 and the second liquid inlet pipe 222 are provided with counterweight structures.

[0039] Thus, when the drone tilts during its movement, the ends of the first liquid inlet pipe 221 and the second liquid inlet pipe 222 can remain at the lowest position of the first space 201 or the second space 202, so that the first liquid inlet pipe 221 and the second liquid inlet pipe 222 can draw cleaning fluid from the bottom of the first space 201 and the second space 202.

[0040] Furthermore, an air pump 50 is connected to the drain pipe 41 of the water pump 40. The input end of the air pump 50 is connected to the atmosphere, and the output end is connected to the drain pipe 41.

[0041] In this way, by intermittently controlling the operation of the air pump 50, air segments can be injected into the drain pipe 41. The air segments are compressed during transportation, and through these intermittent air segments, a pulsed water flow is formed, which has a stronger impact on the curtain wall surface and can achieve a better cleaning and decontamination effect.

[0042] The drain pipe 41 includes an upwardly extending straight pipe section. The output end of the air pump 50 is connected to the straight pipe section of the drain pipe 41, and its direction is perpendicular to or at an acute angle to the straight pipe section. For example, the air pump 50 may be inclined upward or horizontal in the pipeline delivery direction. When the air pump 50 is turned on, it draws in external air and forms an air section in the drain pipe 41.

[0043] In conjunction with the above embodiments, the water supply tank proposed in this utility model is equipped with two cavities, which can hold two concentrations of cleaning solution. The delivery status of the two concentration solutions is controlled by a three-way valve, which allows for the flexible use of different concentrations of cleaning solution for different stains, achieving higher cleaning efficiency. In addition, by installing an air pump on the water supply pipe, air can be injected into the water supply pipe to form a pulsed water spray effect, which creates multiple impacts on the wall surface during cleaning, achieving better cleaning results.

[0044] In this embodiment of the utility model, the three-way valve used above adopts a conventionally designed selectable three-way valve, that is, a two-way selection to complete the liquid supply.

[0045] In another optional embodiment, the three-way valve can also be a three-way valve with proportional adjustment function, i.e., a three-way regulating valve. In this utility model, a confluence-type three-way regulating valve is used, which has two inlets. After the confluence, the liquid flows out from one outlet to complete the liquid supply. This allows the liquid ratio of two concentrations of cleaning liquid to be adjusted, and the concentration of the sprayed cleaning liquid to be adjusted. Therefore, different concentrations of cleaning liquid can be used flexibly for cleaning according to different curtain wall cleaning difficulties.

[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
