[0002] In order to reduce weight, low-altitude curtain wall cleaning robots in the prior art generally adopt a water return circulation operation mode, that is, a circulating water circuit is formed between the water filtration system in the machine body and the cleaning scraper unit, but this water return circulation mode is limited to a certain angle range. For example, the robot body can only return water in the forward and horizontal states. When it is not in these two states, the robot cannot achieve water return circulation. Therefore, when the cleaning robot performs tilt rotation and reversing, it can only perform trajectory motion and cannot perform the cleaning function, which seriously affects the cleaning operation efficiency of the curtain wall cleaning robot.

[0003] Therefore, there is an urgent need on the market for a curtain wall cleaning robot that can realize omnidirectional and all-angle return water circulation operations, so as to better solve the problem in the prior art that the curtain wall cleaning robot can only perform trajectory motion when rotating and reversing and cannot perform circulating return water cleaning.

[0049] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0050] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0051] Combination Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides an omnidirectional water-gas separation device, which includes a water-gas separator 1, a water inlet pipe 2 and a water outlet pipe 3; a cyclone centrifugal component 11 for centrifugal separation of water and gas is arranged inside the water-gas separator 1; the water inlet pipe 2 is conductively connected to the water inlet of the water-gas separator 1; the water outlet pipe 3 is conductively connected to the water outlet of the water-gas separator 1; wherein, the cyclone centrifugal component 11 separates the water-gas separator 1 into a water inlet chamber 12 and a water outlet chamber 13 surrounding and wrapping the outside of the water inlet chamber 12; one end of the water outlet pipe 3 is movably installed at the center of the water outlet chamber 13 through a bearing 31, and the other end is bent and extended to form a water suction head 32 facing the inner wall of the water outlet chamber 13; the water outlet pipe 3 can rotate with the bearing 31 under the action of its own gravity, so that the water suction head 32 is always at the bottom of the water outlet chamber 13.

[0052] The omnidirectional water-gas separation device can be specifically but not limitedly applied to water-gas separation in a circulating water circuit of a curtain wall cleaning robot, and this example is used to illustrate the use process.

[0053] When the omnidirectional water-gas separation device is used, the water supply pump can guide the water gas to be separated to the water inlet of the water-gas separator 1 through the water inlet pipe 2. The cyclone centrifugal element 11 in the water-gas separator 1 can produce a centrifugal effect on the water gas during its rotation, and the water droplets are thrown into the inner wall of the water outlet chamber 13 through the generated cyclone force, and the water droplets will accumulate on the inner wall of the water outlet chamber 13 and be guided to the bottom of the water outlet chamber 13 under the action of gravity.

[0054] At the same time, the water outlet pipe 3 in the water-gas separator 1 is movably installed at the center of the water outlet chamber 13 through the bearing 31, and is bent and extended to form a water suction head 32 facing the inner wall of the water outlet chamber 13, so that the water outlet pipe 3 as a whole is eccentrically arranged with respect to the center of the water outlet chamber 13, that is, the water outlet pipe 3 can rotate with the bearing 31 under the action of its own gravity, ensuring that the water suction head 32 can always be at the bottom of the water outlet chamber 13 under the action of gravity, so that no matter what the tilt position of the omnidirectional water-gas separation device is in, the water flow accumulated in the water outlet chamber 13 and the water suction head 32 in the water outlet pipe 3 can be at the bottom of the water outlet chamber 13 under the action of gravity, thereby ensuring that the water outlet pipe 3 can pump out the water flow in the water outlet chamber 13 in real time and uninterruptedly.

[0055] To sum up, the omnidirectional water-gas separation device provided in the embodiment of the present disclosure can make the water suction head 32 in the water outlet pipe 3 rotate eccentrically downward and maintain self-stability under the action of gravity no matter how large the inclination angle is, thereby ensuring that the water in the water-gas separator 1 can be pumped out by the water outlet pipe 3 in real time and continuously.

[0056] The omnidirectional water-gas separation device is applied to the curtain wall cleaning robot. Even if the curtain wall cleaning machine rotates and changes direction at any angle during the cleaning track, the return water circulation system therein can still supply cleaning water to the cleaning scraper unit normally, greatly improving the cleaning operation efficiency of the curtain wall cleaning robot.

[0057] Moreover, in addition to being able to perform 360° rotation and reversing in a vertical glass surface with an angle of 90°, the omnidirectional water vapor separation device can also perform 360° rotation and reversing in an inclined glass surface with an angle greater than or less than 90°. Therefore, the omnidirectional water vapor separation device can also be additionally used for return water circulation cleaning of domes, awnings or large curved buildings.

[0058] In one embodiment, the water outlet pipe 3 further includes an eccentric weight block 33 ; the eccentric weight block 33 is eccentrically arranged on the water outlet pipe 3 , and can make its own gravity act on the bearing 31 to form an eccentric torque.

[0059] Specific, combined Figure 1 To further explain in detail, an eccentric counterweight 33 is additionally provided in the water outlet pipe 3, and the eccentric counterweight 33 can make its own gravity act on the bearing 31 to form an eccentric torque, so that the eccentric counterweight 33 can be but not limited to being set as a counterweight lead block, a counterweight iron block, etc., so that the eccentric torque acting on the bearing 31 by the water outlet pipe 3 as a whole under the action of gravity will be greater, even if the omnidirectional water vapor separation device performs a small angle rotation and reversing, the water outlet pipe 3 can quickly and sensitively perform an adaptive downward rotation, and can quickly maintain self-stabilization.

[0060] Moreover, the above-mentioned eccentric counterweight block 33 can be specifically arranged on the outer pipe wall of the water outlet pipe 3, or in the pipe wall of the water outlet pipe 3, or on the inner pipe wall of the water outlet pipe 3, so as to realize the function of making the gravity of the eccentric counterweight block 33 act on the bearing 31 to form an eccentric torque.

[0061] In one embodiment, the water outlet pipe 3 includes a first pipe section and a second pipe section that are connected to each other; one end of the first pipe section is inserted into the bearing 31 and is installed correspondingly at the center of the water outlet chamber 13; one end of the second pipe section is vertically connected to the other end of the first pipe section, and the other end of the second pipe section is connected to the water suction head 32; the water suction head 32 is arranged as a whole in an inclined direction away from the second pipe section; the eccentric counterweight block 33 is arranged at the end of the second pipe section close to the water suction head 32.

[0062] Specific, combined Figure 1 and Figure 3 To further explain in detail, the water outlet pipe 3 is configured to include a first pipe section and a second pipe section that are connected to each other, and one end of the first pipe section is inserted into the bearing 31 and correspondingly installed at the center of the water outlet chamber 13, and the other end is vertically connected to the second pipe section, and the suction head 32 is connected to the other end of the second pipe section, and the whole is inclined and extends in a direction away from the second pipe section, so that the water outlet pipe 3 as a whole is similar to a "Z" shape, and only the second pipe section and the suction head can generate a large eccentric torque acting on the bearing 31 under the action of gravity, and the eccentric counterweight block 33 can be correspondingly arranged at the pipe wall of the second pipe section or the pipe wall of the suction head 32, so that the water outlet pipe 3 can form a very large gravity eccentric torque, which fully ensures that the water outlet pipe 3 can quickly, sensitively and adaptively rotate downward when rotating with the water-gas separator 1, and can quickly maintain self-stability.

[0063] In one embodiment, an exhaust duct 15 is also opened at the center of the water inlet chamber 12; one end of the exhaust duct 15 is connected to the exhaust port 152 of the water-gas separator 1, and the other end is correspondingly connected to the water outlet chamber 13 through an exhaust head 151; the exhaust head 151 is installed and connected to the outer pipe wall of the second pipe segment, and extends in the opposite direction to the second pipe segment; and the exhaust head 151 can rotate synchronously when the water outlet pipe 3 rotates.

[0064] Specific, combined Figure 1 and Figure 2 To further explain in detail, an exhaust duct 15 is also opened at the center of the water inlet chamber 12, and one end of the exhaust duct 15 is connected to the exhaust port 152 of the water-gas separator 1, and the other end is correspondingly connected to the water outlet chamber 13 through the exhaust head 151. In this way, the exhaust duct 15 will not affect the normal activity and installation of the cyclone centrifugal component 11 in the water inlet chamber 12 on the one hand, and the exhaust duct 15 can timely discharge the air in the water outlet chamber 13 through the exhaust port 152 to the outside, so as to avoid excessive accumulation of air in the water outlet chamber 13 to generate high pressure, and avoid hindering the normal centrifugal delivery of water droplets by the cyclone centrifugal component 11 to the water outlet chamber 13.

[0065] Moreover, in order to prevent water in the water outlet chamber 13 from entering the exhaust head 151 and being discharged outward through the exhaust duct 15, the exhaust head 151 is also installed and connected to the outer pipe wall of the second pipe section, and the exhaust head 151 is arranged to extend in the opposite direction to the second pipe section, so that the exhaust head 151 can rotate upward synchronously when the water outlet pipe 3 rotates downward, ensuring that the exhaust head 151 can always adapt to the top of the water outlet chamber 13.

[0066] The specific arrangement of the exhaust duct 15 and the exhaust head 151 has the beneficial effects of simple structure, being able to discharge the air in the water outlet chamber 13 and avoiding the generation of high pressure in the water outlet chamber 13, being able to adaptively rotate upward under the action of gravity and preventing the water flow from being accidentally discharged from the exhaust duct 15.

[0067] In one embodiment, an inclined cut surface is formed at one end of the exhaust head 151, and an annular docking edge 151a is formed at the other end; the exhaust head 151 is movably docked with the exhaust duct 15 via the annular docking edge 151a, and a sealing ring is also provided at the docking point.

[0068] Specific, combined Figure 1 and Figure 3 To further explain in detail, one end of the exhaust head 151 is specifically configured as an inclined cut surface, which can increase the air intake area of ​​the exhaust head 151 and improve the exhaust pressure relief efficiency of the exhaust head 151.

[0069] In addition, the exhaust head 151 is movably docked with the exhaust duct 15 via the annular docking edge 151a, and a sealing ring is provided at the docking point. In this way, when the water outlet pipe 3 rotates under the action of the eccentric torque generated by gravity, the annular docking edge 151a in the exhaust head 151 can be rotated relative to the exhaust duct 15, so that the exhaust head 151 can automatically rotate upward without hindering the automatic downward rotation of the water outlet pipe 3, and the annular docking edge 151a is sealed and connected to the exhaust duct 15 through the sealing ring, which can effectively prevent the water flow in the water outlet chamber 13 from entering the exhaust duct 15.

[0070] The specific arrangement of the exhaust head 151 has the beneficial effects of being simple in structure, being able to automatically rotate along with the water outlet pipe 3 and improving the exhaust sealing performance of the exhaust duct 15 .

[0071] In one possible implementation manner, the water-gas separator 1 further comprises an adapter 4 sealed and docked with the water outlet end of the water outlet pipe 3; and the adapter 4 is movably docked with the water outlet pipe 3 via a universal adapter.

[0072] Specific, combined Figure 1 and Figure 2 To further explain in detail, the water-gas separator 1 also includes an adapter 4 that is sealingly docked with the water outlet end of the water outlet pipe 3, and the adapter 4 is movably docked with the water outlet pipe 3 through a universal adapter. On the one hand, this can improve the docking seal between the adapter 4 and the water outlet pipe 3. On the other hand, since the water outlet end of the water outlet pipe 3 is movably sleeved with a bearing 31, and the water outlet pipe 3 needs to rotate with the bearing 31, a universal adapter is set when the adapter 4 is docked for connection. In this way, the adapter 4 can be fixedly set in the water-gas separator 1, and the rotation of the water outlet pipe 3 will be offset by the universal adapter.

[0073] Moreover, the adapter 4 can be used to connect with the pipeline in the circulating water circuit, so as to realize the water flow separated by the water-gas separator 1 to be led out and continue to enter the cleaning scraper unit for use.

[0074] In one possible implementation manner, the water-gas separator 1 further includes a filter element 14 ; the filter element 14 is sleeved on the outer periphery of the cyclone centrifugal element 11 .

[0075] Specific, combined Figure 1 To further explain in detail, the water-gas separator 1 is also provided with a filter element 14 on the outer periphery of the cyclone centrifugal element 11, so that the filter element 14 can, on the one hand, remove impurities from the water flow centrifuged by the water-gas separator 1, and on the other hand, the filter element 14 can also improve the water-gas separation efficiency of the water-gas separator 1 to a certain extent.

[0076] Of course, when the omnidirectional water-gas separation device is applied to a curtain wall cleaning robot, a filtering device is also correspondingly provided in the return water circulation system of the curtain wall cleaning robot, and the filtering device is mainly used to remove impurities from the sewage after the use of the cleaning scraper unit, and after filtering by the filtering device, it is guided to the water-gas separator 1 of the omnidirectional water-gas separation device for water-gas separation.

[0077] In one embodiment, the water-gas separator 1 also includes a fixed base 18, a cavity shell 17 and a cavity cover 16; the cavity cover 16 is correspondingly mounted on the cavity shell 17 through a sealing snap-fit ​​structure, and together with the cavity shell 17, it encloses a water inlet chamber 12 and a water outlet chamber 13; the installation side of the fixed base 18 is respectively provided with a snap edge for sealing and clamping the cavity shell 17, and a fitting edge for sealing and clamping the water-gas separator 1.

[0078] Specific, combined Figure 1 , Figure 2 and Figure 4 To further explain in detail, the water vapor separator 1 also includes a fixed base 18, a cavity shell 17 detachably installed in the fixed base 18, and a cavity cover 16 detachably covered in the cavity shell 17, so that the cavity cover 16 is correspondingly covered on the cavity shell 17 through a sealing snap-fit ​​structure, and forms an inlet chamber 12 and a water outlet chamber 13 in the water vapor separator 1; the installation side of the fixed base 18 can seal and clamp the cavity shell 17 through a snap-fit ​​edge, and can seal and clamp the water vapor separator 1 through a set edge, so that a sealed and stable connection of the overall frame structure of the water vapor separator 1 can be achieved.

[0079] The specific arrangement of the fixed base 18, the cavity shell 17 and the cavity cover 16 has the beneficial effects of simple structure, easy processing and manufacturing, convenient disassembly and firm assembly.

[0080] In addition, the embodiment of the present disclosure also provides a curtain wall cleaning robot, which includes a cleaning machine body 5 and the above-mentioned omnidirectional water-gas separation device; a filter 51, a water tank 52 and a cleaning scraper 53 are provided in the cleaning machine body 5, and are respectively connected to the water-gas separator 1 through connecting pipes to form a return water circulation system.

[0081] Specific, combined Figure 5 To further explain in detail, the cleaning machine body 5 in the curtain wall cleaning robot has a filter 51, a water tank 52 and a cleaning scraper 53, and is connected to the water vapor separator 1 in the omnidirectional water vapor separation device through a connecting pipe to form a return water circulation system, so that automatic cleaning of the curtain wall can be achieved, and the curtain wall cleaning robot rotates and reverses along the curtain wall in the cleaning trajectory, and the return water circulation system can still normally supply cleaning water to the cleaning scraper 53, which greatly improves the cleaning operation efficiency of the curtain wall cleaning robot.

[0082] In addition, in addition to being able to perform 360° rotation and reversing on a 90° vertical glass surface, the curtain wall cleaning robot can also perform 360° rotation and reversing on an inclined glass surface greater than or less than 90°. Therefore, the curtain wall cleaning robot can also be additionally used for return water circulation cleaning of domes, awnings or large curved buildings.

[0083] In addition, the curtain wall cleaning robot includes the above-mentioned omnidirectional water-gas separation device, which can achieve all the beneficial effects thereof, and no additional explanation will be given here.

[0084] In one possible implementation manner, the cleaning machine body 5 further includes a negative pressure fan 54 ; the negative pressure fan 54 is correspondingly connected to the exhaust port 152 in the water-gas separator 1 .

[0085] Specific, combined Figure 5 To further explain in detail, a negative pressure fan 54 is also provided in the cleaning machine body 5, and the negative pressure fan 54 is correspondingly connected to the exhaust port 152 in the water vapor separator 1, so that the negative pressure fan 54 can generate a negative pressure suction effect, so that the air in the water outlet chamber 13 in the water vapor separator 1 can be effectively and quickly discharged through the exhaust port 152.
