[0043] In the embodiments of the present application, the operating rod component 100, the driving component and the barrier clearing component 200 are arranged to realize the daily operation and maintenance barrier clearing operation, on this basis, the vibration energy during work is amplified by the cantilever component 420, the kinetic energy of the cantilever component 420 is collected by the energy collection assembly 410 and converted into electric energy, the generated electric energy is collected by the electric energy module 500 and supplied to the driving component, so that an external power supply is not needed, the portability is provided, and the barrier clearing efficiency and the use convenience are improved.

[0044] It can be understood that, in some embodiments, the operating rod component 100 is used as a base carrier, the clearing component 200 and the driving component are carried, the driving component drives the clearing component 200 to move, the obstacle cleaning in daily operation and maintenance is completed, the cantilever component 420 amplifies the vibration of the operating rod and the clearing component 200, sufficient kinetic energy is provided for the energy collection component 410, the collection efficiency is improved, the amount of electrical energy conversion is guaranteed, the energy collection component 410 and the electrical energy module 500 form a self-powered system, an external power supply or a battery is not needed, the weight of the device is reduced, and the use is limited, the driving component continuously obtains electricity to guarantee the continuity of the clearing, and all components are integrated through the operating rod component 100, and portability and operation coordination are considered.

[0045] In some embodiments, the clearing component 200 can include various clearing tools, different types of tools are selected and used according to different application scenarios, on this basis, the clearing tools can be directly arranged on the operating rod component 100, or can be indirectly arranged on the operating rod component 100 by using an intermediate connecting structure. In some embodiments, the driving component is used to drive the clearing component 200, when the clearing component 200 includes various clearing tools, the driving component correspondingly includes a plurality of driving members, each driving member is used to drive each clearing tool, at this time, the driving member can be directly arranged on the operating rod component 100, or can be indirectly arranged on the operating rod component 100 by using an intermediate connecting structure.

[0046] In some embodiments, the driving component driving the clearing component 200 to move can include linear reciprocating motion or rotation, vibration and the like, so as to realize the obstacle cleaning operation in daily operation and maintenance. Specifically, corresponding transmission members can be designed according to actual use requirements to realize corresponding transmission effects, and when the clearing component 200 is designed to be detachably connected, the driving component can drive the intermediate transmission member to move through the transmission member, and the clearing component 200 is detachably arranged on the intermediate transmission member, so as to realize the effect of the driving component driving the clearing component 200 to work.

[0047] Exemplarily, in some embodiments, the electrical energy module 500 includes functions such as collection, conversion, storage, output and the like, so that after the generated electrical energy is collected, the electrical energy is converted into a usable or storable state, and the electrical energy is output to the driving component.

[0048] The clearing device disclosed in the embodiments of the present application will be explained and described in detail. Figures 1 to 4 The clearing device disclosed in the embodiments of the present application will be explained and described in detail.

[0049] In some embodiments of the present application, the energy collection assembly 410 includes a first permanent magnet 411 and a coil component 412, and the energy collection mechanism 400 further includes a fixed frame 430; the other end of the cantilever component 420 is movably connected to the fixed frame 430; the first permanent magnet 411 is arranged near the other end of the cantilever component 420 and is used to generate a magnetic field around the fixed frame 430; the coil component 412 is arranged on the fixed frame 430, and the coil component 412 is used to cut the magnetic field when the cantilever component 420 swings and relatively displaces with the fixed frame 430; and the electric energy module 500 is connected to the coil component 412 and collects the generated electric energy.

[0050] It can be understood that the movement and vibration of the operating rod component 100, the driving component and the obstacle removing component 200 swing the cantilever component 420 and drive the fixed frame 430 to move, and the relative movement occurs based on the inertia of the swing, thereby driving the first permanent magnet 411 to relatively displace with the coil component 412 on the fixed frame 430; according to the electromagnetic induction law, when the coil component 412 cuts the magnetic field of the first permanent magnet 411, the induced current is generated in the coil, and the kinetic energy of the cantilever swing is converted into electric energy; the electric energy module 500 is connected to the coil component 412, collects the induced current and supplies the driving component.

[0051] In some embodiments, the sliding connection between the fixed frame 430 and the other end of the cantilever component 420 can be achieved by a sliding groove, a sliding block limiting and the like, so as to improve the energy conversion efficiency. In some embodiments, a spring is arranged between the fixed frame 430 and the other end of the cantilever component 420, so as to improve the frequency of the relative movement and the stability of the overall structure.

[0052] It should be understood that, in order to improve the efficiency of converting vibration energy into electrical energy, in some embodiments, the energy harvesting assembly 410 includes a second permanent magnet 413 and a base 414; the base 414 is arranged in the fixed frame 430 and used to place the coil component 412; the second permanent magnet 413 is arranged on the base 414 and located in the coil component 412, and the second permanent magnet 413 repels the first permanent magnet 411 in polarity, so as to increase the magnetic flux change rate. It can be understood that the base 414 is used to position the coil component 412 to ensure the stability of the coil position, while carrying the second permanent magnet 413 and placing it inside the coil component 412 to construct a basic magnetic field structure. When the cantilever swings to drive the first permanent magnet 411 to approach or move away from the second permanent magnet 413, the repulsive force will intensify the interaction between the magnetic fields of the two, thereby greatly improving the change amplitude and rate of the magnetic flux in the coil component 412. According to the electromagnetic induction law, the induced current size is positively correlated with the magnetic flux change rate, so as to further amplify the electrical energy conversion efficiency of the energy harvesting assembly 410. By repelling the polarity to enhance the magnetic flux change rate, the induced current generated by the coil is stronger, providing more sufficient electrical energy for the driving component, and ensuring the continuous and efficient operation of the obstacle removing component 200.

[0053] It should be noted that, based on the high gradient and bidirectional symmetry of the repulsive magnetic field, the peak value of the induced electromotive force can be greatly improved, the magnetic field focusing effect is stronger, the leakage is reduced, the reciprocating motion is adapted, the high-frequency response is good, and the energy storage efficiency is high. In the initial state, the magnetic field of the second permanent magnet 413 stably passes through the coil. Then when the first permanent magnet 411 approaches, the two like-pole magnets generate a strong repulsive force. The magnetic field of the first permanent magnet 411 counteracts and suppresses the magnetic field of the second permanent magnet 413. Then the result is that the upward magnetic induction lines generated by the second permanent magnet 413 in the coil are largely canceled by the downward magnetic induction lines of the first permanent magnet 411. The net magnetic flux passing through the coil is sharply reduced. A strong induced electromotive force will be generated in the coil during this rapid magnetic flux reduction. In addition, the strong repulsive force can even push the first permanent magnet 411 and the second permanent magnet 413 to move relatively further, thereby generating additional and stronger electromotive force.

[0054] In some embodiments, the center of the coil component 412, the second permanent magnet 413 and the first permanent magnet 411 are on the same vertical line, so as to further improve the magnetic flux change rate.

[0055] In some embodiments, the energy collection mechanism 400 comprises an elastic component 440, and the other end of the cantilever component 420 is connected to the first permanent magnet 411 through the elastic component 440. It can be understood that, by using the elastic deformation characteristics of the elastic component 440, when the cantilever swings due to the vibration of the operating rod and / or the clearing component 200, the elastic component 440 is stretched or compressed synchronously with the swing of the cantilever component 420, thereby prolonging the swing time of the first permanent magnet 411, stabilizing the swing amplitude, and further improving the frequency and stability of the first permanent magnet 411 cutting the coil magnetic field, and improving the energy conversion efficiency.

[0056] In some embodiments, the elastic component 440 can be a spring, one end of the spring is connected to the cantilever component 420, and the other end is connected to the first permanent magnet 411.

[0057] In some embodiments, the cantilever component 420 is provided at least two, one end of each cantilever component 420 is arranged on the operating rod component 100 in a spaced manner, and the other end of each cantilever component 420 is slidably connected to the fixed frame 430. It can be understood that, the spaced distribution of the multiple cantilever components 420 can uniformly disperse the vibration load of the operating rod component 100, and can synchronously capture the vibration energy at different positions of the operating rod component 100. At the same time, based on the sliding connection of the multiple cantilever components 420 and the fixed frame 430, the swing stability of the cantilever component 420 is ensured, the structural stress is balanced, the motion stability is improved, and the conversion accuracy is guaranteed.

[0058] In some embodiments, each cantilever component 420 is provided with a piezoelectric material component 415, and the fixed frame 430 is also provided with a corresponding coil component 412, a first permanent magnet 411 and a second permanent magnet 413, so that each cantilever component 420 can realize composite power generation through piezoelectric material and induced electromotive force.

[0059] In some embodiments of the present application, the clearing component 200 comprises a first clearing tool 210 and a second clearing tool 220, and the driving component comprises a first driving member 310 and a second driving member 320; the first driving member 310 is used to drive the first clearing tool 210 to act, and the second driving member 320 is used to drive the second clearing tool 220 to act; the first clearing tool 210 is arranged at the end of the operating rod component 100, and the second clearing tool 220 is arranged on the fixed frame 430. It can be understood that, the first clearing tool 210 is arranged at the end of the operating rod as the main working end, and the second clearing tool 220 is arranged on the fixed frame 430 as the auxiliary working end, forming a position complement, and the first driving member 310 and the second driving member 320 are correspondingly configured to provide independent power for the two clearing tools, thereby guaranteeing the independent operation of the double clearing tools and adapting to complex and various types of obstacles in operation and maintenance.

[0060] In some embodiments, the first clearing tool 210 can be configured as a positioning cone, a remote control electric claw, a main knife, a saw, a clearing screw cone, a rope cutting knife, a clearing hook, or a horizontal wheel according to the use requirements. The second clearing tool 220 can be provided as a blade or other tool matched with the first clearing tool 210.

[0061] It can be understood that the clearing device in the related art has a single function and cannot realize multi-dimensional clearing actions such as rubbing, poking, and cutting. In some embodiments, the operating rod component 100 includes a rod body 110 and a connecting seat 120, the connecting seat 120 is detachably arranged at the end of the rod body 110, the first clearing tool 210 is detachably arranged on the connecting seat 120, and the first driving member 310 is arranged in the rod body 110 and used to drive the first clearing tool 210 to act;

[0062] It can be understood that the rod body 110 serves as a basic bearing frame of the operating rod component 100, provides holding support and internal space, the connecting seat 120 is connected to the end of the rod body 110 through detachable design such as buckling and threaded connection, the first clearing tool 210 is then detachably arranged on the connecting seat 120, and the first driving member 310 is built in the rod body 110, drives the first clearing tool 210 or drives the connecting seat 120 to drive the first clearing tool 210 to move synchronously through the transmission structure, transmission shaft, and cable inside the rod body 110. For different obstacles, only the old tool needs to be disassembled and the new tool needs to be arranged, without the need to replace the entire operating rod component 100. The standardized interface of the connecting seat 120 can be compatible with a plurality of specifications of the first clearing tool 210, solves the poor adaptability problem, and greatly improves the coverage capability of the device for complex operation and maintenance scenes.

[0063] In some embodiments, the connecting seat 120 can be connected to the rod body 110 or the first clearing tool 210 through threaded connection. In some embodiments, the connecting seat 120 can be connected to the rod body 110 or the first clearing tool 210 through plug-in connection, which can be specifically provided as a quick-release connector or a plug-in connecting seat 120 and other commonly used and convenient disassembly structures.

[0064] It can be understood that the clearing device in the related art is mostly designed without folding storage, resulting in poor portability and large storage space occupation. In some embodiments, the second driving member 320 is arranged on the fixing frame 430, and the second clearing tool 220 is arranged in or out of the fixing frame 430. It can be understood that the second clearing tool 220 is completely embedded in the fixing frame 430 when it is stored, without protruding outward, which greatly reduces the overall volume of the device, adapts to outdoor backpack carrying and narrow space operation scenes, and can be normally used when it is extended, thereby optimizing the space occupation and strengthening the portability.

[0065] In some embodiments, the second obstacle removing tool 220 is movably arranged on the fixing frame 430, a spring acts on the second obstacle removing tool 220, the fixing frame 430 is provided with a limiting structure and an unlocking button, the second obstacle removing tool 220 is limited by the limiting structure when moving to the limiting structure to achieve storage, the limiting of the second obstacle removing tool 220 by the limiting structure is released by pressing the unlocking button, and the spring drives the second obstacle removing tool 220 to reset, so that the second obstacle removing tool 220 extends and can work.

[0066] In order to further improve the collection efficiency of vibration energy, a composite vibration energy collection mode can be used, and in some embodiments of the present application, the energy collection assembly 410 includes a piezoelectric material component 415 arranged on the cantilever component 420 and connected with the electric energy module 500, which is used to convert vibration energy into electric energy. It can be understood that the piezoelectric material component 415 such as piezoelectric ceramic or piezoelectric film generates polarization charge inside the material under the action of mechanical stress to form induced current to realize energy conversion. After being fixed on the cantilever component 420, it can directly capture the mechanical vibration when the cantilever swings. The bending and stretching of the cantilever will produce continuous extrusion or tensile stress on the piezoelectric material, which will promote the material to generate stable induced electric energy. The electric energy is collected together with the electric energy generated by the electromagnetic induction of the permanent magnet and the coil, and is transmitted to the electric energy module 500 for storage, forming a double-path energy conversion system of electromagnetic collection and piezoelectric collection. Without changing the cantilever structure and without occupying additional space, the vibration energy during operation is maximized, and the self-power supply capability is strengthened.

[0067] In some embodiments, the piezoelectric material component 415 is arranged on the upper and lower surfaces of the cantilever component 420 respectively, thereby improving the energy collection efficiency. The direct mounting of the piezoelectric material and the cantilever can reduce the transmission loss of vibration energy.

[0068] In some embodiments, the circumferential side wall of the operating rod component 100 is provided with a clamping groove 130, one end of the cantilever component 420 is provided with an insert 421, and the cantilever component 420 is arranged on the operating rod component 100 by inserting the insert 421 into the clamping groove 130. It can be understood that the clamping groove 130 of the operating rod circumferential side wall and the insert 421 at the end of the cantilever component 420 form precise shape matching, realizing quick fixing of the two, the circumferential layout of the clamping groove 130 can flexibly adjust the installation angle and interval of the cantilever component 420, and the fitting constraint of the insert 421 and the clamping groove 130 limits the displacement of the cantilever component 420, ensuring that the vibration energy of the operating rod is efficiently transmitted to the cantilever component 420.

[0069] In some embodiments, the connecting seat 120 of the operating rod component 100 is provided with the clamping groove 130 on the circumferential side wall, and the cantilever component 420 is indirectly arranged on the rod body 110 of the operating rod component 100 by being connected to the connecting seat 120. Further, according to the number of cantilever components 420, the connecting seat 120 with a corresponding number of clamping grooves 130 can be used for connection, thereby improving the convenience of use through modular design.

[0070] In some embodiments, the connecting seat 120 is provided with a groove space on the circumferential side wall, and the clamping groove 130 is located in the groove space, so that after the cantilever component 420 is inserted into the clamping groove 130 through the insert 421, the groove space can provide sufficient space for the swing of the cantilever component 420.

[0071] It can be understood that the obstacle removing device in the related art lacks modular assembly function, and it is difficult to adapt to different positions and different types of obstacles, and the whole set of equipment needs to be frequently replaced, which increases cost and reduces work efficiency. For this problem, in some embodiments, the energy collection mechanism 400 is provided in multiple numbers, and each energy collection mechanism 400 is arranged on the circumferential side wall of the operating rod component 100 at intervals.

[0072] It can be understood that each energy collection mechanism 400 includes a cantilever component 420 and an energy collection assembly 410 (combination of electromagnetic and piezoelectric), which is arranged at intervals through the clamping groove 130 of the operating rod circumferential side wall, can capture vibration energy in different directions of the operating rod at 360°, each mechanism independently converts vibration kinetic energy in the corresponding direction into electrical energy, all electrical energy is collected to the electrical energy module 500 for unified storage and distribution, forming a multi-directional and multi-unit composite energy collection system, which maximizes the available energy of the operation vibration without increasing the size of the device.

[0073] In some embodiments, the energy collection mechanisms 400 are evenly arranged at intervals on the circumferential side wall of the operating rod component 100.
