Description

A cleaning device and its application in drones Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning device and its application in drones. Background Technology

[0002] Existing cleaning devices typically consist of a spray nozzle connected to the water inlet. The spray force of the nozzle can be adjusted by changing the water pressure of the spray gun, and the spray range can be adjusted by changing the water flow control outlet at the nozzle nozzle.

[0003] However, the existing cleaning device is limited by the structure of a single nozzle, which restricts its spraying range and affects cleaning efficiency. In certain working conditions, such as working at height, it is inconvenient to adjust the water flow control outlet and lacks flexibility in adjusting the spraying range. In addition, when it is necessary to replace the nozzle, the existing cleaning device can only be lowered to the ground for replacement, which further affects cleaning efficiency.

[0004] Utility Model Content

[0005] This utility model provides a cleaning device and its application to drones, which solves the problems of existing cleaning devices with a single nozzle having a limited spray range, lack of flexibility in adjusting the spray range, inconvenience in replacing nozzles, and reduced work efficiency.

[0006] One embodiment of this utility model provides a cleaning device, including a diversion adapter and a multi-channel spray pipe assembly. The diversion adapter is connected to the end of the water inlet pipe, and each spray pipe assembly is connected to a branch connector of the diversion adapter. One or more spray pipe assemblies are provided with a switch device, which is used to control the on / off state of the corresponding spray pipe assembly.

[0007] Furthermore, each spraying pipeline assembly includes a front-end adapter, a spray pipe, an end adapter, and a nozzle. The front-end adapter is connected between the branch joint of the diversion adapter and the front end of the spray pipe, and the end adapter is connected between the end of the spray pipe and the nozzle.

[0008] Furthermore, the switching device is connected between the flow divider and the nozzle, or the switching device is connected between the nozzle and the spray head.

[0009] Furthermore, the cleaning device also includes a water inlet pipe, the cross-sectional area of ​​which is greater than or equal to the cross-sectional area of ​​each spray pipe.

[0010] Furthermore, the number of spray pipe assemblies is two or more, and the cleaning device also includes a fixing component. The fixing component includes a support rod and a pipe connector. The support rod is disposed between multiple spray pipe assemblies, and the pipe connector is connected between the support rod and the spray pipe.

[0011] Furthermore, the spraying pipeline assemblies are arranged in parallel relative to each other.

[0012] Furthermore, the pipeline connector includes a sliding collar and a support rod unit. The sliding collar is sleeved on the surface of the support rod and slides relative to the support rod. One end of the support rod unit is hinged to the outer wall of the sliding collar, and the other end is hinged to the spray pipe of the corresponding spray pipeline assembly. The cleaning device also includes a power device for driving the sliding collar to slide. When the sliding collar slides on the support rod, each spray pipeline assembly expands or converges radially along the support rod under the drive of the sliding collar and the corresponding support rod unit.

[0013] Furthermore, the fixing assembly also includes a root connector located at the root of the support rod, the root connector also includes a fixing groove into which the support rod extends, and a mounting unit located on one or more sides of the fixing groove, the mounting unit including a switch mounting surface or a front adapter mounting surface;

[0014] The switching device is a solenoid valve or a pneumatic valve.

[0015] Furthermore, the cleaning device also includes a housing with a fixed arm for connecting to the drone.

[0016] Another embodiment of this utility model provides a drone, including the drone body and the cleaning device described in any of the above claims. The cleaning device is directly connected to a water inlet pipe or is connected to a water inlet pipe through a water inlet pipe interface.

[0017] This embodiment of the invention connects the inlet pipe to the cleaning device via a diversion adapter. Spray pipe assemblies are installed at each diversion joint of the adapter. These spray pipe assemblies can be arranged in parallel or at an angle relative to a specific point. A switching device on one or more spray pipe assemblies controls their on / off state. This allows the user to control the number of spray pipe assemblies connected to the cleaning device as needed. Each spray pipe assembly is equivalent to a traditional spray pipe, offering a large spray range and high flexibility in adjusting the spray range. Furthermore, when different nozzles are required for special working conditions, the cleaning device of this embodiment can equip different spray pipe assemblies with corresponding nozzles. By controlling the on / off state of the spray pipe assemblies with different nozzles, rapid nozzle switching is achieved without descending to the ground to change nozzles, greatly improving the efficiency of high-altitude operations. Additionally, when using a relatively small number of spray pipe assemblies for cleaning, the spray force of the cleaning device can be significantly enhanced. Compared to existing cleaning devices, this increases the upper limit of spray force, meeting the operational needs of more working conditions or scenarios. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of this utility model, unless they actually express the meaning of order according to the context, they should be understood as being used only for differentiation.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] First embodiment:

[0033] This embodiment provides a cleaning device, including a diversion adapter and a multi-way spray pipe assembly. The diversion adapter is connected to the end of the water inlet pipe, and each spray pipe assembly is connected to a branch connector of the diversion adapter. One or more spray pipe assemblies are provided with a switching device, which is used to control the on / off state of the corresponding spray pipe assembly.

[0034] In this embodiment, the number of the above-mentioned spraying pipeline assemblies can be two or more, and the spraying pipeline assemblies can be arranged in parallel or at a fixed angle relative to a specific point. Each spraying pipeline assembly is equipped with a switch device for independent on / off control, and the nozzles of each spraying pipeline assembly can be of different types.

[0035] The switching device in this embodiment can be a pneumatic valve, which can be remotely controlled via a communication module.

[0036] This embodiment of the invention connects the inlet pipe to the cleaning device via a diversion adapter. Spray pipe assemblies are installed at each diversion joint of the adapter. These spray pipe assemblies can be arranged in parallel or at an angle relative to a specific point. A switching device on one or more spray pipe assemblies controls their on / off state. This allows the user to control the number of spray pipe assemblies connected to the cleaning device as needed. Each spray pipe assembly is equivalent to a traditional spray pipe, offering a large spray range and high flexibility in adjusting the spray range. Furthermore, when different nozzles are required for special working conditions, the cleaning device of this embodiment can equip different spray pipe assemblies with corresponding nozzles. By controlling the on / off state of the spray pipe assemblies with different nozzles, rapid nozzle switching is achieved without descending to the ground to change nozzles, greatly improving the efficiency of high-altitude operations. Additionally, when using a relatively small number of spray pipe assemblies for cleaning, the spray force of the cleaning device can be significantly enhanced. Compared to existing cleaning devices, this increases the upper limit of spray force, meeting the operational needs of more working conditions or scenarios.

[0037] Second embodiment:

[0038] Referring to Figures 1 to 5, this embodiment provides a cleaning device, including a water inlet interface 12, a diversion adapter 1, and two spray pipe assemblies. The diversion adapter 1 is a T-shaped pipe connected to the end of the water inlet interface 12. Each spray pipe assembly is connected to a branch connector of the diversion adapter 1. One of the spray pipe assemblies is equipped with a switch device, which is a solenoid valve 2, used to control the on / off state of the corresponding spray pipe assembly.

[0039] Each spraying pipeline assembly includes a front-end adapter 3, a spray pipe 4, an end adapter 5, and a nozzle 6. The front-end adapter 3 is connected between the branch joint of the diversion adapter 1 and the front end of the spray pipe 4, and the end adapter 5 is connected between the end of the spray pipe 4 and the nozzle 6.

[0040] The solenoid valve is connected between the diversion adapter 1 and the spray pipe 4. Specifically, in this embodiment, the three-way pipe is arranged laterally. The water inlet pipe interface 12 and the front end adapter of one spray pipe assembly are respectively connected to the two ends of the long pipe of the three-way pipe. The front end connector of the other spray pipe assembly is connected to the solenoid valve 2. One end of the solenoid valve 2 is connected to the spray pipe of the other spray pipe assembly, and the other end is connected to the short pipe of the three-way pipe through a bend.

[0041] It should be noted that, as can be understood from the above description, when connecting different pipelines, switching devices and nozzles, due to the different corresponding interface specifications, those skilled in the art can select different types of front-end adapters or end-end adapters as needed, so that the front-end adapters, end-end adapters and nozzles corresponding to different spray pipeline components are different. All substitutions or evolutions based on the concept of this utility model are within the protection scope of this utility model.

[0042] As a specific solution and not a limitation, the cleaning device also includes a water inlet pipe connected to the front end of the water inlet pipe interface 12, wherein the cross-sectional area of ​​the water inlet pipe is greater than or equal to the cross-sectional area of ​​each spray nozzle. Preferably, in this embodiment, the cross-sectional area of ​​the water inlet pipe is approximately twice the cross-sectional area of ​​each spray nozzle, in order to further increase the upper limit of the spray force and enable the cleaning device to meet the operational needs of more working conditions or scenarios.

[0043] In this embodiment, the cleaning device further includes a fixing component, which includes a support rod 7 and a pipe connector 8. The support rod 7 is disposed between two spray pipe assemblies, and the pipe connector 8 is connected between the support rod 8 and the spray pipe 4.

[0044] Specifically, in this embodiment, the spray pipe assemblies are arranged in parallel relative to each other. The pipe connector 8 includes a pipe connector body, a support rod positioning hole in the middle of the pipe connector body, and spray pipe positioning holes on both sides of the support rod positioning hole corresponding to the spray pipe.

[0045] The fixing assembly also includes a root connector 9 located at the base of the support rod 7. The root connector 9 also includes a fixing groove into which the support rod extends, and an installation unit located on one or more sides of the fixing groove. The installation unit includes a switch mounting surface or a front adapter mounting surface.

[0046] Specifically in this embodiment, the fixing groove of the root connector 9 is formed in the middle of the fixing sleeve 91, and the fixing sleeve has an installation unit on one side. The installation unit includes a groove 92, and the surface of the groove 92 has a front end adapter mounting surface. The installation unit also has an arc-shaped notch 93 at the front end for the nozzle to extend out.

[0047] As a preferred option and not a limitation, the cleaning device in this embodiment is further provided with a diamond-shaped bracket 13 on the other side of the root connector 9 relative to the mounting unit.

[0048] The cleaning device also includes a housing 10, on which a fixed arm 11 for connecting to a drone is provided.

[0049] This embodiment simplifies the structure of the cleaning device by setting up two spray pipe assemblies, which are arranged in parallel relative to each other, and a switching device is installed on one of the spray pipe assemblies. This reduces the weight of the cleaning device, ensures the drone's endurance, and facilitates long-term cleaning operations. Furthermore, because the T-junction is positioned laterally, the arrangement of the two spray pipe assemblies is more compact, saving space and volume. This cleaning device is typically used when using the same cleaning solution (water or foaming agent). One spray pipe assembly without a switching device is normally open. When the spray intensity needs to be increased, the switching device keeps the other spray pipe assembly closed; when the spray range needs to be expanded, the switching device controls the other spray pipe assembly to operate, thus meeting the operational needs of various working conditions or scenarios.

[0050] Third embodiment:

[0051] Referring to Figures 6 to 10, this embodiment provides a cleaning device, including a diversion adapter 1' and two spray pipe assemblies. The diversion adapter 1' is a three-way pipe connected to the end of the water inlet pipe. Each spray pipe assembly is connected to a branch connector of the diversion adapter 1'. Unlike the second embodiment described above, both spray pipe assemblies in this embodiment are equipped with a switch device, which is a solenoid valve 2', used to control the on / off state of the corresponding spray pipe assembly.

[0052] Furthermore, unlike the second embodiment described above, since both spray pipe assemblies in this embodiment are equipped with solenoid valves 2', the three-way pipe in this embodiment can be arranged in the forward direction. The front end adapters of the two spray pipe assemblies are respectively connected to the two ends of the long pipe of the three-way pipe through bends 15', and the short pipe of the three-way pipe is used to connect to the end of the external water inlet pipe.

[0053] Furthermore, unlike the second embodiment described above, the fixing groove of the root connector 9' is formed in the semi-enclosed groove 91' in the middle of the root connector 9'. The semi-enclosed groove 91' has mounting units on both sides, and the mounting units on both sides are arranged in opposite directions. The mounting unit includes a solenoid valve 2' mounting plate 92' which serves as the mounting surface of the switch device, and an arc-shaped mounting surface 93' located at the front of the mounting plate 92' which serves as the mounting surface of the front end adapter. The front end of the arc-shaped mounting surface 93' is also provided with an arc-shaped notch 94' for the nozzle to extend out.

[0054] As a preferred option rather than a limitation, in this embodiment, the arc-shaped notches 94' on both sides of the root connector 9' are semi-circular notches, and the axes of the arc-shaped notches 94' on both sides are coplanar with the bottom surface of the semi-enclosed groove 91'.

[0055] The cleaning device includes an outer shell 10'. It also includes an inner shell 14' located below the root connector 9'. The root connector 9' extends downward from the right-side mounting unit to form several mounting columns 95'. The mounting columns 95' are used to fix the inner shell 13'. The inner shell 14' is used to house at least the circuit components for controlling the solenoid valve 2', so as to further improve the waterproofness of the circuit components and ensure the working stability of the cleaning device.

[0056] This embodiment incorporates switching devices on both spray pipe assemblies, enabling each assembly to operate independently. While one assembly sprays water, the other can spray foam, accommodating situations where the same cleaning device sprays water and foam sequentially. Furthermore, the reversed mounting units on both sides of the root connector maximize space efficiency while ensuring adequate space for the switching devices, thus extending the drone's flight time and facilitating extended cleaning operations.

[0057] Fourth embodiment:

[0058] This embodiment provides a cleaning device. Unlike the second or third embodiment described above, the number of spray pipe assemblies in this embodiment can be three or more. The pipe connector includes a sliding collar and a support rod unit. The sliding collar is sleeved on the surface of the support rod and slides relative to the support rod. One end of the support rod unit is hinged to the outer wall of the sliding collar, and the other end is hinged to the spray pipe of the corresponding spray pipe assembly. The cleaning device also includes a power device for driving the sliding collar to slide. When the sliding collar slides on the support rod, each spray pipe assembly expands or converges radially along the support rod under the drive of the sliding collar and the corresponding support rod unit.

[0059] As a specific embodiment and not a limitation, the aforementioned power unit can be a cylinder or an electric actuator, which can be remotely controlled via a communication module. In this embodiment, the nozzle is made of metal or hard plastic.

[0060] As a specific solution rather than a limitation, the number of sliding collars in this embodiment is one, the support rod unit corresponds one-to-one with the spray pipe assembly, all support rod units are evenly distributed in the circumferential direction centered on the support rod axis, and all spray pipe assemblies are also evenly distributed in the circumferential direction centered on the support rod axis.

[0061] This embodiment further defines the pipeline connector as a sliding collar and a support rod unit. The sliding collar is sleeved on the surface of the support rod and slides relative to the support rod. One end of the support rod unit is hinged to the outer wall of the sliding collar, and the other end is hinged to the nozzle of the corresponding spray pipeline assembly. The cleaning device also includes a power device for driving the sliding collar to slide. When the sliding collar slides on the support rod, each spray pipeline assembly expands or converges radially along the support rod under the drive of the sliding collar and the corresponding support rod unit. This allows the user to adjust the expansion angle of the spray pipeline assembly as needed. When large-area cleaning is required, by controlling the sliding collar to slide towards the nozzle, the support rod unit drives each spray pipeline assembly to expand radially along the support rod, achieving a larger spray area and further increasing the adjustment flexibility of the cleaning device of this utility model.

[0062] Fifth embodiment:

[0063] This embodiment provides a drone, including the drone body and the cleaning device described in any of the above-mentioned claims. The cleaning device is directly connected to the water inlet pipe or is connected to the water inlet pipe through the water inlet pipe interface.

[0064] This embodiment of the invention connects the inlet pipe to the cleaning device via a diversion adapter. Spray pipe assemblies are installed at each diversion joint of the adapter. These spray pipe assemblies can be arranged in parallel or at an angle relative to a specific point. A switching device on one or more spray pipe assemblies controls their on / off state. This allows the user to control the number of spray pipe assemblies connected to the cleaning device as needed. Each spray pipe assembly is equivalent to a traditional spray pipe, offering a large spray range and high flexibility in adjusting the spray range. Furthermore, when different nozzles are required for special working conditions, the cleaning device of this embodiment can equip different spray pipe assemblies with corresponding nozzles. By controlling the on / off state of the spray pipe assemblies with different nozzles, rapid nozzle switching is achieved without descending to the ground to change nozzles, greatly improving the efficiency of high-altitude operations. Additionally, when using a relatively small number of spray pipe assemblies for cleaning, the spray force of the cleaning device can be significantly enhanced. Compared to existing cleaning devices, this increases the upper limit of spray force, meeting the operational needs of more working conditions or scenarios.

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
