The height of the operation scene is usually within 20 meters, the length of a conventional operation rod is insufficient, and if a spider man lifting rope is used for cleaning operation, the efficiency is low and the cost is high; if mechanical elevating devices such as scaling ladders are adopted, then manual operation is carried out, the purchasing cost of equipment is high, and heavy equipment is troublesome to transport in different operation places. Both of these solutions are costly, making cleaning of these sites difficult to implement.

In addition, municipal facilities such as lamp posts, lighting fixtures, road sign boards, tunnel inner walls, ceilings, subway station outer vertical surfaces, wall surfaces and ceilings of underground stations and the like; in the application occasions of agriculture, municipal greening and the like, branches are trimmed at high altitude, fruits are picked up and the like; in the photovoltaic power generation case, the cleaning equivalent of large-scale photovoltaic panels requires a low-cost extended cleaning solution.

At present, in all application scenes, only one method is available at home and abroad, namely, the lifting or the extension in the ground direction is realized through sleeving an extension rod. The simple method for sleeving and extending the operation rod faces the situation that the gravity center of the rod is far away from the operator, and the outer end of the rod body forms a basic mechanical model with extremely large moment relative to one end of the operator, so that even if the outer end has small weight or small operation external force, the moment at one end of the operator is far beyond the limit of the body strength of the operator through the moment amplification of the long rod. In popular terms, the long rod cannot be lifted up, and is not hard to use. In practice, the rod body which can be actually operated extends far, usually within 7 meters, if the rod body is too long, the outer end of the rod body is seriously deformed or even broken, and effective operation cannot be performed, so that the length can not meet the requirements of the operation scene.

Example 1:

referring to fig. 1, the present embodiment discloses a vector thrust auxiliary extension apparatus, which includes a stick unit 100, a working unit 600, a vector thrust unit 200, a pivoting unit 300, and a control unit 400.

Specifically, the rod unit 100 is formed of a carbon fiber tube with a length of 10 meters, one end of which is used for a user to grasp and operate, and the other end of which is used for connecting the operation unit 600 to operate the operation area, and in this embodiment, the operation unit 600 adopts a detachable brush for cleaning the scene such as the exterior wall of a building.

The vector thrust unit 200 is movably connected to the rod body unit 100, the vector thrust unit 200 is provided with 2 controllable-sized thrust driving mechanisms, and thrust generated by the thrust driving mechanisms can overcome the weight of the vector thrust unit 200 and part of the weight of the rod body unit 100.

Specifically, as shown in fig. 2, the vector thrust unit 200 includes two thrust driving mechanisms disposed in groups, each of which includes a cross member 201 and a driving member. The beam 201 is used for connecting two driving members arranged at intervals, and plays a role of connecting and bearing. The driving member adopts an electric propeller, the output direction of a propeller blade of the propeller is downward, the propeller provides an upward thrust for the vector thrust unit 200 after rotating at a high speed, and the thrust can at least overcome part of the weight of the vector thrust unit 200 and the rod body unit 100.

Further, the beam 201 is fixedly connected to the rod unit 100 and is in transmission connection with the pivoting unit 300 to perform a pivoting movement, which causes the driving member to swing on an axial plane of the rod unit 100, that is, the pivoting movement of the beam causes the driving member to swing longitudinally (in a pitch angle direction of the rod unit 100).

In this embodiment, as shown in fig. 2, the driving member is composed of a propeller motor 202, a propeller blade 203, a protection frame 205, and a propeller electric power unit 206. Wherein, 2 screw motors 202 are fixed in both ends about crossbeam 201 through first mounting 204, and first mounting 204 is locking external member structure. The 2 propeller motors 206 are fixedly arranged on the beam 201 near the first fixing piece 204 and connected with a power line of the propeller motor 202 to control the driving speed of the propeller motor 202.

Two centrally symmetrical propeller blades 203 are disposed at the output end of each propeller motor 202, and the propeller motors 202 can drive the propeller blades 203 to rotate at a high speed in a directional manner, so that the propeller blades 203 generate downward blowing to form a reverse upward thrust, namely a vector thrust (supporting force), during the rotation process, and the thrust is used for overcoming the self weight of the vector thrust unit 200 and part of the weight of the rod body unit 100.

Further, in order to improve the safety of the product, unnecessary extra contact is avoided in the high-speed rotation state during the operation of the helical blade, the outer periphery of the helical blade 203 is provided with a protecting frame 205, the protecting frame 205 is fixedly connected with the tail end of the cross beam 201 through a supporting rod 207 and a second fixing piece 209, and the supporting rod 207 enables the structure of the protecting frame 205 to be always kept fixed. In order to enable the vector thrust unit 200 to be placed stably in the idle state, a support structure is arranged at the bottom of the protection frame 205, the support structure is specifically a support column 208 arranged at the bottom of the support column 207, the support column 208 is arranged vertically, and the bottom end of the support column 208 can be abutted against the ground to play a supporting effect in the idle state or after the vector thrust unit 200 is disassembled, so that the whole vector thrust unit 200 can be placed stably on the ground.

In order to improve the operation efficiency and stability of the vector thrust unit 200, the cross beam 201 is vertically disposed with the rod unit 100, that is, the cross beam 201 is in a horizontal state after being assembled, and forms an operation plane together with the single unit 100, and the two driving members are symmetrically disposed at the left and right ends of the cross beam 201, the cross beam 201 can connect the two driving members to form a whole, and the cross beam 201 extends in a transverse layout, so that the operation areas of the two driving members can be separated by extending outwards, and the balance controllability of the operation plane is improved.

In order to reduce the weight load, the cross beam 201 and the protection frame 205 are hollow tube structures.

The pivoting unit 300 is disposed between the vector thrust unit 200 and the stick unit 100 to enable the vector thrust unit 200 to perform an assembly angle change with respect to the stick unit 100.

As shown in fig. 3, in order to increase the accuracy and controllability of the vector thrust output direction, the pivot unit 300 includes a rotating shaft 303, and the rotating shaft 303 is fixedly connected to the rod unit 100 through a third fixing member 301. The axial one end transmission of pivot 303 is connected with the pivot driving piece, and in this embodiment, this pivot driving piece adopts pivot motor 304, and pivot motor 304 can direct drive pivot 303 rotatory, the radial one end of pivot 303 passes through fourth mounting 302 and connects crossbeam 201, and after the assembly, crossbeam 201 perpendicular to body of rod unit 100, pivot motor 304 can drive pivot 303 and drive crossbeam 201 and carry out the rotation on the transverse plane for vector thrust direction swings in the pitch angle direction of monomer unit 100.

Further, in order to prevent the cross beam 201 from over rotating, which results in interference between the structures, the pivoting unit is further provided with a limiting structure for limiting the rotation stroke of the rotating shaft 303, and in this embodiment, the limiting structure is specifically a limiting claw 306 disposed on one radial side of the third fixing member 301.

And an attitude sensor 305 is arranged on one side of the third fixing frame, so that the working condition of the vector thrust unit 200 is accurately detected in real time, and the parameter information of the transverse rotation, the pitching and the heading angle of the transverse beam 201 is actually monitored. The gesture sensor 305 is in signal connection with the control unit 400.

The control unit 400 comprises a communication module, a power module and a data processing module, wherein the communication module is used for receiving a remote control signal and feeding back an operation state; the power supply module is specifically a dry battery or a liquid storage battery and is used for supplying power, and the data processing module is used for receiving and calculating and processing the sensing signals and the remote control signals, generating corresponding running instructions and feeding back the corresponding running instructions to corresponding components. The above modules are integrated in the case and are fixedly mounted on the rod unit 100, and the above modules are all of the prior art, and the specific structure and the working principle according to which the structure is operated are not described herein.

In this embodiment, in order to prevent the cables from being messy, the distribution paths of the cables on the rod unit 100 are all provided with fixing clips.

In order to facilitate the operation and flexibly control the components of the device, the device further comprises a remote control unit 500, wherein the remote control unit 500 is arranged at one end of the rod unit 100 far away from the operation unit 600, the remote control unit 500 is used for a user to operate and control the driving components, and the remote control unit 500 comprises a display screen and buttons for man-machine interaction.

The driving members located at both sides of the cross member 201 are a first propeller a1 and a second propeller a2, respectively.

In operation, referring to fig. 4, the first propeller a1 generates downward wind force F1, the reaction force of F1 is upward F1', the second propeller a2 generates downward wind force F2, and the reaction force of F2 is upward F2', when the directions of F1 and F2 are equal, the resultant force of F1 and F2 is vertical downward F, so that the vector thrust unit 200 obtains a vertical upward reaction force F, opposite to the direction of F, in this state, only generates a vertical upward auxiliary thrust, which can help the vector thrust unit 200 and the rod unit 100 to perform longitudinal support and keep the longitudinal posture stable or perform the longitudinal (pitch angle direction of the rod unit 100) movement actively, and realize the movement control of the rod unit 100 in the pitch angle.

In operation in conjunction with fig. 5, when the wind force F2 generated by the second propeller a2 is greater than the wind force F1 generated by the first propeller a1, that is, the reaction force F2 'of F2 is greater than the reaction force F1' of F1, the resultant force of F1 and F2 generated by the second propeller a2 is F-sum (the F-sum direction in the drawing is toward the right lower direction), which is offset to one side in the horizontal direction, so that the vector thrust unit 200 obtains a reaction force F-sum '(the F-sum direction in the drawing is toward the left upper direction) which is opposite to the F-sum direction, in which not only a longitudinal upward assist thrust is generated, but also a horizontal deflection force is generated because of the restriction of the connection point of the cross beam 201 to the rod body unit 11 (the connection point is located at the middle position of the cross beam 201 in the present embodiment), and the reaction force F2' generated by the second propeller a2 is decomposed into F2'x and F2' y in the horizontal direction, respectively, and the reaction force F1 'generated by the first propeller a1 is decomposed into F1' x and F1'y in the horizontal direction respectively in the horizontal direction, which is greater than the horizontal deflection force x 1' x. Therefore, the reaction force fclose' corresponding to fclose can not only help the body unit 100 obtain the control capability of lifting/lowering, but also make the body unit 100 obtain the control capability of shaft pointing, that is, can synchronously perform the active control of pitch angle and heading angle on the body unit 100. In the specific implementation process, through the driving force of the first propeller a1 and the second propeller a2 and the active control of the pivoting unit 300, the pitch angle and the course angle of the rod unit 100 can be synchronously and actively controlled, and the movement control of the rod unit 100 in the roll angle direction (the axial rotation direction of the rod unit 100) can be easily handled through the holding and matching of operators. Thereby, when the rod body unit 100 is lifted far, the operation plane has the capacity of resisting transverse crosswind, and the rod body unit cannot be toppled by the transverse crosswind, so that the safety of lifting operation is ensured.

Further, referring to fig. 7, when the pivoting unit 300 actively adjusts the angle of the cross beam 201, the cross beam 201 drives the entire vector thrust unit 200 to swing longitudinally, and the swing change affects the direction of the wind force F generated by the propeller, so that the obtained direction of the F pushing can also be actively adjusted. This structure can achieve lifting and lowering of the stick unit 100 according to the intention of the operator, and additionally provide working force of the distal end of the stick unit 100.

Therefore, by synchronously adjusting the rotation speeds of the two propellers, differentially adjusting the rotation speeds of the two propellers, and actively adjusting the angles of the cross beam 201 and the vector thrust unit 200 by the pivot unit 300, thrust changes with different effects can be obtained, and operation and control can be performed independently or cooperatively to obtain different expected effects.

As shown in fig. 8, it is preferable that the angle between the rotation planes of the two blades of the first and second propellers a1 and a2 is 120-170 degrees through experimental tests.

In the implementation, if the vector thrust is output in the radial direction of the rod (as shown in fig. 4), if the vector thrust is perpendicular to the ground, the vector thrust can bear the weight of the rod together with the operator and independently bear the weight of the working unit 600. The shaft can be lifted or lowered by increasing or decreasing the radial thrust according to the control command of the operator. The vector thrust loads a part or most of the weight of the rod body, so that the moment amplification effect formed by the fact that the center of gravity of the rod body is far away from an operator is relieved, the long rod lengthened to twenty-three meters can be lifted off the ground easily by the operator, meanwhile, the long rod is always output in the operation process, and the weight of the rod body is loaded, so that the labor intensity of the operator is greatly reduced.

The vector thrust is positioned on the radial output plane of the rod body, when the vector thrust rotates around the radial axis direction of the rod body, an included angle is formed between the vector thrust and the gravity direction, a horizontal component perpendicular to the gravity direction is generated, when the component faces the working surface, the expected working force during extension operation, such as the downward pressure to the wall surface, can be realized, and when the component faces the left side and the right side, the component can be used for resisting transverse wind, so that the working plane is kept stable.

The vector thrust unit 200 cooperates with the extension operation of the rod adding unit 100, solves the problem that the traditional rod body cannot be lifted up and cannot be forced up after extension and extension, and enables low-cost covering low-altitude operation to be possible.

Example 2:

on the basis of embodiment 1, when the length of the stick body unit 100 exceeds 15 meters, the single vector thrust unit 200 may not match the stick body weight support, and thus, as shown in fig. 9, two sets of vector thrust units 200 are provided for adaptation so as to meet the operation requirement.

In other embodiments, the drive may also employ an electrically powered ducted fan.

In other embodiments, the work unit 600 may be configured as a saw, a pair of electric scissors, a pair of electric saw blades, a pair of wipers, or the like.

In other embodiments, the stick unit 100 has a stick structure with an adjustable length in order to flexibly adapt to the height requirements in different working scenarios. Specifically, the rod unit 100 may adopt a structure in which a plurality of rods are inserted into each other or a telescopic rod structure.

In other embodiments, an image capturing module may be further disposed on the operation unit 600, for performing real-time observation or image capturing recording on a specific scene of the operation area.

In other embodiments, the remote control unit 500 may also be configured to be detachable from the rod unit 100, and then be worn on the arm of the fixed operator by using the wearing structure, or may even be provided with an intelligent sensing system for identifying the operation intention of the operator, such as lifting, lowering, rotating direction, etc., or may be manually controlled by the operator to output the operation instruction through the entity crank, and the remote control device transmits the control instruction to the target driving component for running through a wireless or signal line.

In other embodiments, the power supply may be connected to an external utility power by a cable and a transformer, providing a basic energy guarantee for long-term operation.

In other embodiments, the third fixing member 301 may also adopt a hinge structure, so that the beam 201 and the rod unit 100 can rotate relatively, and the rotation direction is located on a radial plane of the rod unit 100. A rotation driving structure adapted to the third fixing member 301 may be further added for active rotation control.

In other embodiments, the propeller may be further connected to the beam 201 by adopting a universal connection structure and a wind direction control system, so that the controllability of the rod unit 100 is more diversified and high-precision.
