Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of line maintenance tools, and is an automatic tree barrier cleaning device. BACKGROUND

[0002] A power transmission network transports electricity from a power plant to various substations and solves the problem of long-distance power transmission. A distribution network connects power consumers to the power transmission network or directly to a power plant. Each year, power companies need to send special personnel to regularly patrol the power transmission and distribution networks to monitor the operation of the lines, promptly identify defects and potential hazards along the lines that threaten the safe operation of the lines, and reduce the occurrence of line accidents.

[0003] For different voltages, there is a corresponding minimum safety distance. For example, for voltages of 10 kV and below, the safety distance is 0.7 meters, and for voltages of 20-35 kV, the safety distance is 1 meter. If the distance is less than this distance, there is a risk of discharge, which can cause a series of hazards, such as equipment tripping, equipment burning, widespread power outages, and personnel electrocution and injury.

[0004] For line maintenance, tree barrier cleaning is the most common and frequent safety hazard for power companies. The tree barrier hazard problem of a general power company refers to the trees on both sides of the transmission and distribution lines that are naturally growing and have a distance from the lines that is less than the safety distance. Cleaning these tree barriers requires sending special personnel to prune the trees near the lines to meet the safety distance requirement. Currently, tree barrier cleaning operations are performed by workers holding electric saws or oil saws and standing on a boom truck to perform the operation. There are two risks in the operation process. One is the risk of falling for workers due to accidental operation or shaking of the support during the operation. The second is that during the operation process, due to insufficient safety distance of the branches, there is a high probability of sharp discharge between the branches and the lines, and the risk of electric shock for personnel due to electrified branches is much higher. For these problems, a tree barrier cleaning device is needed to meet the requirements of high tree barrier cutting operations and to replace manual operations to reduce the occurrence of personal injury accidents. SUMMARY

[0005] The present application provides an automatic tree barrier cleaning device that overcomes the shortcomings of the prior art and effectively solves the problem of high safety risk in existing tree barrier cleaning operations.

[0006] The technical solution of the present invention is achieved through the following measures: an automatic tree clearing device includes a base, a fixed frame, a power frame, an electric saw, a rotating component, and a control unit. The fixed frame has an arc-shaped clamping groove with an opening facing downwards. Several fixed clamps are fixedly installed at intervals on the inner side of the left part of the arc-shaped clamping groove. The right part of the fixed frame is provided with a movable clamp that can be located on the inner side of the right part of the arc-shaped clamping groove after moving to the left, and a driving mechanism that can make the movable clamp move left and right. The lower right part of the fixed frame is fixedly installed together with the upper front part of the base. The lower side of the base is provided with an installation groove that matches the operating head. The power frame is fixedly installed on the upper rear part of the base. An electric saw is provided on the upper side of the power frame. A rotating component that can make the lower part of the drive motor of the electric saw rotate is provided on the base. A control unit and a battery unit are provided at intervals inside the base. The control unit is electrically connected to the battery unit, the drive motor of the electric saw, the rotating component, and the driving mechanism, respectively.

[0007] The following are further optimizations and / or improvements to the above-mentioned technical solution: Two fixed clamps can be fixedly installed at intervals on the inner left side of the aforementioned arc-shaped clamping groove. The driving mechanism includes an electric push rod fixedly installed on the inner right side of the fixed frame. The inner right side of the fixed frame is provided with a sliding groove that connects the inside and outside. The movable clamp is slidably installed in the sliding groove. The right end of the movable clamp is detachably and fixedly installed together with the left end of the push rod of the electric push rod. The electric push rod is electrically connected to the control unit.

[0008] The aforementioned rotating assembly may include a geared motor and a rotating shaft. A forward-backward rotating shaft is fixedly mounted on the upper part of the power frame. The upper left side of the drive motor of the electric saw is fixedly mounted on the outside of the rotating shaft. The geared motor is fixedly mounted on the rear side of the power frame. The front end of the output shaft of the geared motor is driven together with the rear end of the rotating shaft. The geared motor is electrically connected to the control unit.

[0009] The above may also include a remote control unit, which includes a remote control module, a receiving module, and a transmitting module. The remote control module and the transmitting module are electrically connected, the transmitting module and the receiving module are communicatively connected, and the receiving module is electrically connected to the control unit.

[0010] This invention features a reasonable and compact structure. In use, the operator installs the operating head at the top of the insulating rod into the mounting slot, then uses the insulating rod to move the automatic tree-clearing device to the branch that needs cutting. The fixing frame is located on the side closer to the trunk, and the electric saw is located on the side farther from the trunk. The control unit then sends a signal to the drive mechanism, which causes the movable clamp to extend to the left and be fixed to the outside of the branch together with the fixed clamp. The operator then moves away from the work area to avoid being scratched or injured by falling branches. The rotating component then causes the upper end of the electric saw blade to swing downwards, while the electric saw's drive motor moves the blade. The rotating component continuously causes the blade to swing downwards, thus cutting the branch and clearing obstacles formed by trees on both sides of the power transmission line. This method is convenient to operate and highly efficient. Attached Figure Description

Detailed Implementation

[0014] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0015] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0016] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1 , 2 As shown, the automatic tree clearing device includes a base 1, a fixed frame 2, a power frame 3, an electric saw 4, a rotating component, and a control unit. The fixed frame 2 has an arc-shaped clamping groove 6 with an opening facing downwards. Several fixed clamps 5 are fixedly installed at intervals on the inner side of the left part of the arc-shaped clamping groove 6. The right part of the fixed frame 2 is provided with a movable clamp 7 that can be located on the inner side of the right part of the arc-shaped clamping groove 6 after moving to the left, and a drive mechanism that can make the movable clamp 7 move left and right. The lower right part of the fixed frame 2 is fixedly installed together with the upper front part of the base 1. The lower side of the base 1 is provided with a mounting groove 8 that matches the operating head. The power frame 3 is fixedly installed on the upper rear part of the base 1. The electric saw 4 is provided on the upper side of the power frame 3. The base 1 is provided with a rotating component that can make the lower part of the drive motor of the electric saw 4 rotate. The control unit and the battery unit are spaced apart inside the base 1. The control unit is electrically connected to the battery unit, the drive motor of the electric saw 4, the rotating component, and the drive mechanism, respectively.

[0017] Depending on the requirements, the mounting slot 8 can be a threaded slot, with the operating head of the insulating rod screwed into it. Alternatively, the mounting slot 8 can be H-shaped, with the operating head of the insulating rod inserted into it. In use, the operator installs the operating head at the top of the insulating rod into the mounting slot 8, then uses the insulating rod to move the automatic tree-clearing device to the branch that needs cutting. The fixing frame 2 is located on the side closer to the trunk, and the electric saw 4 is located on the side farther from the trunk. The control unit then sends a signal to the drive mechanism, which causes the movable chuck 7 to extend to the left and be fixed to the outside of the branch together with the fixing chuck 5. The operator then moves away from the work area (or the insulating rod can be removed) to prevent being scratched or injured by falling branches. The rotating component then rotates, causing the upper end of the saw blade of the electric saw 4 to swing downwards. Simultaneously, the drive motor of the electric saw 4 drives the saw blade, and the rotating component continuously causes the saw blade of the electric saw 4 to swing downwards. This allows the saw blade of the electric saw 4 to cut the branch, thus clearing obstacles formed by trees on both sides of the power transmission line. The operation is convenient and the work efficiency is high.

[0018] The above-mentioned automatic tree clearing device can be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2 As shown, two fixed clamps 5 are fixedly installed at intervals on the inner left side of the arc-shaped clamping groove 6. The driving mechanism includes an electric push rod 9 fixedly installed on the inner right side of the fixed frame 2. The inner right side of the fixed frame 2 is provided with a sliding groove that connects the inside and outside. The movable clamp 7 is slidably installed in the sliding groove. The right end of the movable clamp 7 is detachably and fixedly installed together with the left end of the push rod of the electric push rod 9. The electric push rod 9 is electrically connected to the control unit.

[0019] Depending on the requirements, the right end of the fixed chuck 5 can be spherical. The movable chuck 7 has the same structure as the fixed chuck 5. The electric push rod 9 is a known technology, such as the SLEL small DC electric telescopic rod. The right end of the movable chuck 7 and the left end of the push rod of the electric push rod 9 are detachably and fixedly installed together by means of a threaded connection. During use, with this setting, after the electric push rod 9 is working, the push rod of the electric push rod 9 extends to the left, driving the movable chuck 7 to move to the left. In this way, the movable chuck 7 and the two fixed chucks 5 press against the surface of the branch, thereby fixing the fixing frame 2 and the branch together. In this way, when the chainsaw 4 is working, it can quickly cut off the branch behind the movable chuck 7. After the cut branch falls to the ground, it can be quickly cleaned up. The fixing frame 2 fixed to the branch can improve the stability of the chainsaw 4 during operation and prevent the automatic tree clearing device from malfunctioning after the cut branch falls.

[0020] Example 3: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2As shown, the rotating assembly includes a geared motor 10 and a rotating shaft 11. The rotating shaft 11 is fixedly mounted on the upper part of the power frame 3 in a front-to-back direction. The upper left side of the drive motor of the electric saw 4 is fixedly mounted on the outside of the rotating shaft 11. The geared motor 10 is fixedly mounted on the rear side of the power frame 3. The front end of the output shaft of the geared motor 10 is connected to the rear end of the rotating shaft 11 in a transmission manner. The geared motor 10 is electrically connected to the control unit.

[0021] According to the requirements, the geared motor 10 is a known technology, such as a stepper motor, a DT series micro rotary platform, or a direct drive motor rotary table. To prevent the saw blade of the chainsaw 4 from jamming, the front end of the output shaft of the geared motor 10 and the rear end of the rotating shaft 11 are connected by a known torque sensor. The torque sensor is electrically connected to the control unit and is a known NT series shaft torque sensor. Thus, when the torque value is within the set range, such as between 20 N•m and 50 N•m, the geared motor 10 and the chainsaw 4 work normally. When the torque value is less than 20 N•m, the saw blade of the chainsaw 4 is above the branch, the chainsaw 4 is not started, and the saw blade of the chainsaw 4 will not cut the branch. When the torque value is greater than 50 N•m, the saw blade of the chainsaw 4 is jammed in the branch. At this time, the control unit causes the drive motor of the chainsaw 4 to stop working, and the geared motor 10 stops rotating forward. After reversing, it resumes cutting the branch when the torque value decreases to the set range. The control unit is a known programmable controller.

[0022] During use, the geared motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 then drives the lower part of the drive motor of the electric saw 4 to rotate upward. In this way, the saw blade of the electric saw 4 can quickly cut branches that pose a hazard to power transmission lines under the combined action of the drive motor and the geared motor 10. When sawing branches, the operators can stay away from the construction area to ensure their safety.

[0023] Example 4: As an optimization of the above examples, as shown in the appendix. Figure 2 As shown, it also includes a remote control unit, which includes a remote control module, a receiving module, and a transmitting module. The remote control module and the transmitting module are electrically connected, the transmitting module and the receiving module are communicatively connected, and the receiving module is electrically connected to the control unit.

[0024] Depending on the requirements, the remote control module, receiver module, transmitter module, and control unit constitute existing known technologies, such as a multi-functional control remote control switch or a TAD series four-way wireless remote control switch. During use, this setup allows operators to remotely operate the automatic tree-clearing device from a safe area, making operation more convenient.

[0025] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
