Description

Technical Field

[0001] The invention relates to the technical field of electric appliances, in particular to an anti-vibration hammer which can obtain energy autonomously and can be actively reset. Background Art

[0002] Anti-vibration hammers are one of the main means to reduce breeze vibration or dancing of transmission lines, but there are many problems with the installation location and subsequent maintenance of anti-vibration hammers.

[0003] Since the anti-vibration hammer should be installed near the anti-node of the vibration wave, it can increase the amplitude of the up and down hysteresis vibration of the anti-vibration hammer, thereby maximizing the consumption of the vibration energy of the wire. However, the frequency of the transmission line resonance varies within a frequency band, and the anti-vibration hammer with a fixed position cannot take into account all frequencies or always be in the best anti-vibration position. In addition, the length, quality, connection method and operating environment of the wire all affect the result to varying degrees.

[0004] The patent application number CN201721127495.X is called a transmission line anti-vibration hammer position adjustment device. It uses a walking obstacle crossing mechanism, a back-resting fixing mechanism, and a loose nut mechanism to reset the anti-vibration hammer, thereby adjusting the position of the anti-vibration hammer. However, this method can only work after the patrol personnel observe the deviation of the anti-vibration hammer. It cannot automatically adjust the position of the anti-vibration hammer on the transmission line in real time according to the current vibration situation. It does not have real-time performance, so it needs to be solved urgently. Summary of the invention

[0005] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides an anti-vibration hammer that can autonomously obtain energy and actively reset, and can adjust the position of the anti-vibration hammer on the transmission line in real time according to the current vibration conditions.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A vibration damper capable of autonomous energy extraction and active reset comprises two frames arranged at intervals along the length direction of a power transmission line and a travel clamping mechanism installed on the two frames, wherein the travel clamping mechanism can travel along the length direction of the power transmission line and can form a clamping fit with the power transmission line; acceleration sensors are arranged at both frames; an annular cavity is also arranged at both frames, the axis of the annular cavity is parallel to the axis of the power transmission line, a flow meter is installed inside the annular cavity and a detection fluid flows; the acceleration sensor and the flow meter are both connected to a PLC controller, and the PLC controller controls the movement of the travel clamping mechanism according to a prediction strategy; wherein the prediction strategy is specifically:

[0009] The feedback value of the acceleration sensor at end A or end B and the feedback value of the flow meter are analyzed.

[0015] As a further solution of the present invention: the first V-shaped folding frame is in an inverted V-shaped structure with an opening facing downward, and a second V-shaped folding frame with an inverted V-shaped structure and an opening facing downward in the same direction is arranged directly above the first V-shaped folding frame, and both ends of the second V-shaped folding frame are respectively hinged to the two upper side edges of the first V-shaped folding frame through a third hinge shaft, and the axis of the third hinge shaft is distributed parallel to the axis of the first hinge seat, and the two third hinge shafts are symmetrically distributed on both sides of the first hinge seat; a vertically arranged positioning slide bar is fixed to the fixed part of the first hinge seat, and a roller that can roll along the upper surface of the transmission line is installed at the bottom of the positioning slide bar, and the top of the positioning slide bar slides through the fixed part of the second hinge seat in the middle of the second V-shaped folding frame.

[0016] As a further solution of the present invention: the power mechanism includes a power screw rotatably engaged on two frames, a third motor for driving the power screw to rotate is installed on one of the frames, the fixed guide rail and the power screw are arranged along the length direction of the transmission line, and a sliding seat is slidably engaged with the power screw to form a screw slider mechanism, and the power part is constituted by the sliding seat.

[0017] As a further solution of the present invention: the second clamping mechanism includes a fixed column fixed on the upper part of the sliding seat, the fixed column is arranged vertically, and a sliding sleeve is provided with a ring on the fixed column, and a driving part for driving the ring to perform lifting movement is installed on the sliding seat; the top of the fixed column is hinged with two second clamping arms through a fourth hinge axis, and two hinged connecting rods are hinged on both sides of the two rings, which are respectively hinged to the two second clamping arms, and the axis of the fourth hinge axis and the axis of the hinged part of the hinged connecting rod are parallel to the length direction of the transmission line. When the ring rises or falls, the two second clamping arms are driven to clamp or relax relative to the transmission line respectively.

[0018] As a further solution of the present invention: the driving part includes a worm wheel rotatably engaged on both sides of the fixed column, and the rotation axis of the worm wheel is parallel to the length direction of the transmission line, a worm screwed with both worm wheels is arranged between the two worm wheels, and a second motor driving the worm screw to rotate is installed on the slide seat; both sides of the worm wheel are connected to the slide seat through a crank connecting rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. During the vibration of the transmission line, the acceleration sensor and flow meter detect and transmit the detected feedback value to the PLC controller. The feedback values ​​measured by the acceleration sensor and the flow meter are used to check each other, and the position and direction of the anti-node relative to the anti-vibration hammer are determined in real time and accurately. After that, the PLC controller can control the walking clamping mechanism to gradually move the anti-vibration hammer to the anti-node in the determined direction and then clamp it, thereby realizing the automatic real-time adjustment of the anti-vibration hammer in the position of different vibration conditions of the transmission line.

[0021] 2. The structural arrangement of the power supply mechanism enables the magnetic fluid to not only cooperate with the flow meter to determine the position and direction of the anti-node relative to the anti-vibration hammer, but also the magnetic fluid can cut the magnetic flux lines during the flow process, thereby charging the battery and improving the endurance of the anti-vibration hammer.

[0022] 3. The arrangement of at least two groups of annular cavities not only improves the efficiency of charging the battery, but also the instantaneous flow values ​​measured by the flowmeter in the annular cavity in the same annular shell can be mutually verified, further improving the accuracy of determining the position and direction of the antinode relative to the anti-vibration hammer.

[0023] 4. The dual charging design of the battery formed by the solar film absorbing solar energy and the magnetic fluid cutting the magnetic flux lines makes it possible to charge the battery in cloudy and windy weather as well as in sunny and windless weather. The two charging methods complement each other and effectively avoid power failure of the anti-vibration hammer.

[0024] 5. The first clamping mechanism and the second clamping mechanism are used to clamp the transmission line alternately, and when the first clamping mechanism clamps the transmission line, the power unit is used to drive the second clamping mechanism to reciprocate, thereby realizing crawling walking on the transmission line. Since at least the first clamping mechanism or the second clamping mechanism maintains a clamping state with the transmission line during the crawling walking process, the movement of the walking clamping mechanism is not affected by the vibration of the transmission line, thereby ensuring the walking stability of the walking clamping mechanism.

[0025] 6. In the first clamping mechanism, one end of the first V-shaped folding frame is disassembled by a detachable buckle, and the power transmission line can be slid between the two first clamping arms. Thereafter, the first V-shaped folding frame is reset. At this time, the power transmission line is in a closed space formed by the two first clamping arms and the first V-shaped folding frame, which can effectively prevent the anti-vibration hammer from falling from the power transmission line.

[0026] 7. During the crawling process of the walking clamping mechanism, the second clamping mechanism is required to drive the entire frame to move as the clamping support point after the first clamping mechanism is unlocked and relaxed. When the first clamping mechanism is relaxed, the roller on the first clamping mechanism still maintains rolling contact with the upper part of the transmission line, which can assist the second clamping mechanism to maintain a stable clamping action, and further ensure the stability of the walking clamping mechanism during the crawling process.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0033] The specific structure of the present invention refers to Figure 1-3 As shown, its main structure includes two frames 20 arranged at intervals along the length direction of the transmission line a and a traveling clamping mechanism installed on the two frames 20. The traveling clamping mechanism can travel along the length direction of the transmission line a and can form a clamping fit with the transmission line a, thereby realizing the position adjustment of the anti-vibration hammer of the present invention on the transmission line a.

[0034] Further, such as Figure 1 As shown, acceleration sensors 50 are arranged at both frames 20; annular cavities 61 are also arranged at both frames 20, the axis of the annular cavity 61 is parallel to the axis of the power transmission line a, and a flow meter 65 and a detection fluid flow are installed inside the annular cavity 61. When the power transmission line a vibrates, the acceleration sensor 50 is driven to move and detect the acceleration value; at the same time, the detection fluid in the annular cavity 61 flows, and the flow meter 65 detects the instantaneous flow value.

[0035] When the transmission line a vibrates, the vibration amplitude at the antinode of its vibration waveform is the largest. If the anti-vibration hammer is not at the antinode, the acceleration value detected by the acceleration sensor 50 on the anti-vibration hammer closer to the antinode will be greater than the acceleration value detected by the acceleration sensor 50 far from the antinode; similarly, the instantaneous flow value detected by the flow meter 65 on the anti-vibration hammer closer to the antinode will be greater than the instantaneous flow value detected by the flow meter 65 far from the antinode. Based on the above principle, the acceleration sensor 50 and the flow meter 65 are both connected to the PLC controller 68, and the PLC controller 68 controls the movement of the walking clamping mechanism according to the following prediction strategy; wherein the prediction strategy is specifically:

[0036] The two frames 20 are defined as the A end and the B end of the anti-vibration hammer, respectively, and the feedback values ​​of the acceleration sensor 50 at the A end and the B end are compared; the feedback values ​​of the flow meter 65 at the A end and the B end are compared;

[0037] Analyze the feedback value of the acceleration sensor 50 and the feedback value of the flow meter 65 at the A end or the B end. When the two feedback values ​​at either end are relatively large values, the walking clamping mechanism generates a walking action toward that end. The relatively large value is the larger of the same type of values ​​at both ends. For example, the feedback value of the acceleration sensor 50 at the A end is greater than the feedback value of the acceleration sensor 50 at the B end. At the same time, the feedback value of the flow meter 65 at the A end is greater than the feedback value of the flow meter 65 at the B end. This means that the A end is closer to the antinode, so the walking clamping mechanism moves toward the A end. Of course, in actual implementation, the relatively large value may not be the absolute maximum value. In the comparison process of the above feedback values, an interval threshold can be set. When the difference between the two values ​​is within the threshold interval, the two values ​​can be considered to be equal, that is, there is no relatively large value.

[0038] Otherwise, other feedback situations indicate that the anti-vibration hammer is located at the antinode or that the detection result may have an error. At this time, the travel clamping mechanism remains stationary. In this embodiment, during the vibration of the transmission line a, the acceleration sensor 50 and the flow meter 65 detect and transmit feedback values ​​to the PLC controller 68, and the feedback values ​​measured by the acceleration sensor 50 and the flow meter 65 are mutually checked to determine the position direction of the antinode relative to the anti-vibration hammer in real time and accurately. After that, the travel clamping mechanism can be controlled by the PLC controller 68 to gradually move the anti-vibration hammer to the antinode in the determined direction and then clamp it, thereby realizing the automatic real-time adjustment of the anti-vibration hammer at the position of the transmission line a under different vibration conditions.

[0039] On the basis of the above, if Figure 1As shown, a power supply mechanism 60 is fixed at the bottom of the two frames 20, and the power supply mechanism 60 includes an annular housing 66 with an annular cavity 61. A one-way valve 64 is also installed inside the annular cavity 61, and a flow meter 65 is arranged at the outlet end of the one-way valve 64; the detection fluid is a magnetic fluid 63, and permanent magnets 62 are installed on both sides of the cavity inside and outside the annular cavity 61 located at the outlet end of the flow meter 65, and a uniform magnetic field is formed on the flow path of the magnetic fluid 63 through the two permanent magnets 62. When the transmission line a vibrates, the magnetic fluid 63 will circulate in the annular cavity 61, and under the action of the one-way valve 64, the magnetic fluid 63 can only pass through the uniform magnetic field formed by the above-mentioned permanent magnet 62 in one direction, so that the magnetic fluid 63 performs a one-way cutting magnetic flux line movement when flowing through the uniform magnetic field provided by the permanent magnet 62, thereby generating an induced current to charge the battery of the power supply mechanism 60. The structural arrangement of the power supply mechanism 60 enables the magnetic fluid 63 to not only cooperate with the flow meter 65 to determine the position and direction of the antinode relative to the anti-vibration hammer, but also be used to charge the battery to improve the endurance of the anti-vibration hammer.

[0040] Furthermore, the annular cavities 61 in the two annular shells 66 are arranged in at least two groups in sequence along the length direction of the power transmission line a. The arrangement of at least two groups of annular cavities 61 not only improves the efficiency of charging the battery, but also the instantaneous flow values ​​measured by the flowmeter 65 in the annular cavity 61 in the same annular shell 66 can be mutually verified, further improving the accuracy of determining the position and direction of the antinode relative to the anti-vibration hammer.

[0041] On the basis of the above, in order to further improve the endurance of the anti-vibration hammer, such as Figure 1 As shown, a solar film 67 for charging the battery is also installed on the annular shell 66. The dual charging design of the battery formed by the solar film 67 absorbing solar energy and the magnetic fluid 63 cutting the magnetic flux lines enables the battery to be charged in cloudy and windy weather as well as sunny and windless weather. The two charging methods complement each other and effectively avoid power failure of the anti-vibration hammer.

[0042] On the basis of the above, if Figure 1As shown, the traveling clamping mechanism includes a power mechanism 40 and a first clamping mechanism 10 mounted on a frame 20 and capable of clamping with the transmission line a; the power mechanism 40 includes a fixed guide rail 43 connecting two frames 20 and a power unit that can reciprocate along the length direction of the transmission line a, and a second clamping mechanism 30 that can clamp with the transmission line a is mounted on the power unit. In the initial state where the anti-vibration hammer is fixed on the transmission line a, both the first clamping mechanism 10 and the second clamping mechanism 30 are clamped with the transmission line a to ensure the stability of the anti-vibration hammer fixed on the transmission line a. Still taking the two ends of the walking direction of the walking mechanism as end A and end B, when the walking clamping mechanism needs to move toward end A, step one: the first clamping mechanism 10 maintains the clamping state, and the second clamping mechanism 30 is in a relaxed state after being unlocked; step two: the power unit drives the second clamping mechanism 30 to move to the A end to the extreme position relative to the frame 20; step three: the second clamping mechanism 30 clamps the transmission line a again, and the first clamping mechanism 10 is in a relaxed state after being unlocked, with the second clamping mechanism 30 as the force node, the power unit drives the second clamping mechanism 30 to move toward the B end relative to the frame 20, that is, drives the frame 20 to move toward the A end as a whole; if the walking clamping mechanism moves to the desired position at this time, the first clamping mechanism 10 and the second clamping mechanism 30 both restore the initial clamping state, if the walking clamping mechanism has not moved to the desired position at this time, steps one to three are repeated until the walking clamping mechanism moves to the desired position. In the present invention, the first clamping mechanism 10 and the second clamping mechanism 30 are alternately clamped to the transmission line a, and when the first clamping mechanism 10 clamps the transmission line a, the power unit is used to drive the second clamping mechanism 30 to reciprocate, thereby realizing crawling walking on the transmission line a. Since at least the first clamping mechanism 10 or the second clamping mechanism 30 maintains a clamping state with the transmission line a during the crawling walking process, the movement of the walking clamping mechanism is not affected by the vibration of the transmission line a, thereby ensuring the walking stability of the walking clamping mechanism.

[0043] Of course, in actual implementation, the traveling clamping mechanism can also adopt a clamping wheel to clamp the power transmission line a, and drive the clamping wheel to rotate through a motor to achieve a rolling traveling mode on the power transmission line a.

[0044] Specifically, Figure 2As shown, the first clamping mechanism 10 includes two first clamping arms 11 hinged on a first hinge axis at the upper portion of the frame 20, and a first V-shaped folding frame 14 is arranged between the cantilever ends of the two first clamping arms 11; both ends of the first V-shaped folding frame 14 are respectively hinged to the two first clamping arms 11 through a second hinge axis, and the axes of the first hinge axis, the second hinge axis and the first hinge seat in the middle of the first V-shaped folding frame 14 are all parallel to the length direction of the transmission line a, so that when the first V-shaped folding frame 14 is folded or unfolded, the two first clamping arms 11 are driven to clamp or relax relative to the transmission line a respectively. Furthermore, a first motor 15 for driving the first V-shaped folding frame 14 to fold and unfold is installed on one of the first clamping arms 11, and the other first clamping arm 11 is detachably connected to the first V-shaped folding frame 14 via a detachable buckle 17; when in use, one end of the first V-shaped folding frame 14 is disassembled via the detachable buckle 17, and the power transmission line a can be slid between the two first clamping arms 11, and then the first V-shaped folding frame 14 is reset. At this time, the power transmission line a is in a closed space formed by the two first clamping arms 11 and the first V-shaped folding frame 14, which can effectively prevent the anti-vibration hammer from falling from the power transmission line a.

[0045] In actual implementation, in order to ensure the stability of clamping between the first clamping arm 11 and the transmission line a, several first clamps 12 can be fixed on the adjacent sides of the two first clamping arms 11, and the friction pad 13 can be fixed on the inner side of the first clamp 12 to achieve stable clamping with the transmission line a in the largest possible range.

[0046] Further, such as Figure 2As shown, the first V-shaped folding frame 14 is in an inverted V-shaped structure with its opening facing in the same direction, and a second V-shaped folding frame 18 with its opening facing in the same direction is arranged directly above the first V-shaped folding frame 14; the two ends of the second V-shaped folding frame 18 are respectively hinged to the two upper sides of the first V-shaped folding frame 14 through a third hinge shaft, and the axis of the third hinge shaft is parallel to the axis of the first hinge seat, and the two third hinge shafts are symmetrically distributed on both sides of the first hinge seat. A vertically arranged positioning slide bar 161 is fixed to the fixed part of the first hinge seat, and a roller 16 that can roll along the upper surface of the transmission line a is installed at the bottom of the positioning slide bar 161, and the top of the positioning slide bar 161 slides through the fixed part of the second hinge seat in the middle of the second V-shaped folding frame 18. Since the first V-shaped folding frame 14 and the second V-shaped folding frame 18 are folded synchronously, the first hinge seat and the second hinge seat are always located on the same vertical plane. Therefore, the positioning slide bar 161 is fixed to the first hinge seat and slidably cooperates with the second hinge seat, so that the positioning slide bar 161 is always in a vertical state, and the roller 16 is always located on the upper part of the transmission line a. In addition, the first V-shaped folding frame 14 is an inverted V-shaped structure. When the first V-shaped folding frame 14 is unfolded and drives the two first clamping arms 11 to relax, it will drive the roller 16 to move downward to abut against the transmission line a; similarly, when the first V-shaped folding frame 14 is folded and drives the two first clamping arms 11 to clamp, it will drive the roller 16 to move upward to separate from the transmission line a. During the crawling process of the walking clamping mechanism, after the first clamping mechanism 10 is unlocked and relaxed, the second clamping mechanism 30 is used as the clamping support point to drive the entire frame 20 to move. When the first clamping mechanism 10 is relaxed, the roller 16 on the first clamping mechanism 10 still maintains rolling contact with the upper part of the transmission line a, which can assist the second clamping mechanism 30 to maintain a stable clamping action, and further ensure the stability of the walking clamping mechanism during the crawling process.

[0047] It is worth mentioning that Figure 1 As shown, in order to prevent the connecting wires between the motors and the batteries on the two frames 20 from getting tangled, a wire corridor 21 can be fixed between the frames 20 to organize the connecting wires.

[0048] On the basis of the above, if Figure 1-3 As shown, the power mechanism 40 includes a power screw 42 rotatably matched on two frames 20, a third motor 41 driving the power screw 42 to rotate is installed on one of the frames 20, the fixed guide rail 43 and the power screw 42 are arranged along the length direction of the transmission line a, and a slide 31 that forms a screw slider mechanism with the power screw 42 is slidably matched on the fixed guide rail 43, and the slide 31 constitutes the power part. In this solution, the screw slider mechanism is used as the power structure for driving the walking clamping mechanism, which has the advantages of stable transmission and large transmission stroke under the same occupied space compared with other transmission structures such as cylinders.

[0049] On the basis of the above, if Figure 3 As shown, the second clamping mechanism 30 includes a fixed column 32 fixed on the upper part of the slide 31, the fixed column 32 is arranged vertically, and a ring 33 is slidably sleeved on the fixed column 32, and a driving part for driving the ring 33 to perform lifting movement is installed on the slide 31; the top of the fixed column 32 is hinged with two second clamping arms 38 through a fourth hinge axis; two hinged connecting rods 39 are hinged on both sides of the two rings 33, which are respectively hinged to the two second clamping arms 38, and the axis of the fourth hinge axis and the axis of the hinged part of the hinged connecting rod 39 are parallel to the length direction of the transmission line a. When the ring 33 rises or falls, the two second clamping arms 38 are driven to perform clamping or loosening relative to the transmission line a respectively. Since the two first clamping arms 11 and the first V-shaped folding frame 14 in the first clamping mechanism 10 enclose a closed space of the transmission line a, the anti-vibration hammer can be effectively prevented from falling from the transmission line a. Therefore, the second clamping mechanism 30 does not need to set a closed structure at the open end formed by the two second clamping arms 38, thereby ensuring the convenience of installing the anti-vibration hammer. When in use, when the driving unit drives the ring 33 to rise or fall, the hinged connecting rods 39 on both sides of the ring 33 are used to push the two second clamping arms 38 to clamp or loosen the transmission line a synchronously, so as to achieve the clamping and fixing or loosening and unlocking of the second clamping mechanism 30 and the transmission line a. In this embodiment, the lifting force of the ring 33 is converted into a rotational force that drives the two second clamping arms 38 to rotate synchronously, and the two second clamping arms 38 are evenly stressed, so as to achieve stable clamping and fixing of the transmission line a.

[0050] In actual implementation, in order to ensure the stability of the clamping between the second clamping arms 38 and the power transmission line a, a plurality of second clamping heads 381 may be fixed to adjacent sides of the two second clamping arms 38 to achieve stable clamping with the power transmission line a in the largest possible range.

[0051] Further, such as Figure 3 As shown, the driving part includes a worm wheel 36 that rotates and fits on both sides of the fixed column 32, and the rotation axis of the worm wheel 36 is parallel to the length direction of the transmission line a. A worm 35 that meshes with both worm wheels 36 is arranged between the two worm wheels 36, and a second motor 37 that drives the worm 35 to rotate is installed on the slide 31; both sides of the worm wheel 36 are connected to the slide 31 through a crank connecting rod 34. The worm 35 is used to drive the two worm wheels 36 to rotate, and then the two crank connecting rods 34 are used to evenly apply driving force to both sides of the slide 31, ensuring the stable sliding of the slide 31. At the same time, the one-way locking of the worm wheel 36 by the worm 35 can prevent the second clamping arm 38 from self-unlocking when the power is off, and further prevent the anti-vibration hammer from falling after the power is off. Of course, in actual implementation, the driving part can also adopt a linear travel transmission mechanism such as a screw slider mechanism or a cylinder to achieve the lifting movement of the slide 31.

[0052] The first clamping mechanism 10 and the second clamping mechanism 30 may adopt conventional clamping mechanisms in the prior art, such as a cylinder driving two clamping blocks to move closer and farther, so as to achieve clamping and loosening and unlocking between the power transmission line a.

[0053] It is worth mentioning that in order to realize remote control of the anti-vibration hammer, a wireless transmitter 69 can be installed on the anti-vibration hammer and connected to the background computer. If the anti-vibration hammer is in the same position for a long time, the anti-vibration hammer can be controlled by the background computer to slightly adjust its position to avoid the transmission line a being clamped for a long time to form a turning point, which will cause fatigue wear, broken strands and broken wires on the transmission line a.
