Description

Technical Field

[0001] The utility model relates to the technical field of strain clamp detection, and specifically relates to a detection device for a strain clamp on a multi-split conductor. Background Art

[0002] A strain clamp is a fitting used to fix the conductor or lightning protection wire in a transmission line to a non-linear tower (such as a strain tower). Its main function is to bear the tension of the conductor and fix the position of the conductor. Its quality and performance are crucial to the safety and stability of the power system. It is essential to conduct strict detection on the strain clamp.

[0003] A multi-split conductor, also known as a complex conductor or a split conductor bundle, refers to dividing each phase conductor into several smaller-diameter sub-conductors. These sub-conductors maintain a certain distance from each other and are arranged in a symmetric polygon, usually at the vertices of a regular polygon.

[0004] Currently, during the inspection of multi-split conductors, it is necessary to detect the internal structural integrity and potential defects of the strain clamp to ensure the safe operation of the transmission line. In specific implementation, the detection device is carried onto the conductor by a drone, and then the strain clamp is detected by the detection device.

[0005] However, the conductor spacing of multi-split conductors is affected by various factors such as voltage level, conductor specifications, and transmission requirements. Different voltage-level transmission lines adopt different split conductor configurations. The existing transmission line inspection scheme cannot meet the detection requirements of strain clamps on various different specifications of split conductors, and multiple devices are required, resulting in a high cost.

[0006] Based on this, how to improve the adaptability of the existing detection device for strain clamps on multi-split conductors is of great significance to the development of transmission line detection. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a detection device for a strain clamp on a multi-split conductor, which can detect the strain clamps on split conductors with multiple different conductor spacings simultaneously.

[0008] The purpose of the utility model is mainly achieved through the following technical solutions:

[0009] A detection device for a strain clamp on a multi-split conductor includes a frame. The frame is provided with traveling wheels for supporting the frame. The frame is also installed with a ray machine and an imaging plate. There is a space between the ray machine and the imaging plate that can accommodate the strain clamp, and the horizontal distance between the ray machine and the imaging plate is adjustable.

[0010] The traveling wheels are used to move along the conductor, driving the detection device to reach or leave the detection position.

[0011] The frame is used to provide installation positions for the ray machine and the imaging plate.

[0012] The frame covers the outer side surface of the wire. The ray machine and the imaging plate installed on the frame are respectively located on two side surfaces of the frame, so that the ray machine and the imaging plate are respectively located on two opposite outer side surfaces of the wire. The ray machine can emit rays to irradiate the tension clamp in the middle and project onto the imaging plate, which is used to detect the tension clamp on the transmission wire.

[0013] Since the line spacing of multi-split conductors varies with different voltage levels, conductor specifications, and transmission requirements, in the prior art, the horizontal spacing between the ray machine and the imaging plate in the detection device cannot be adjusted, resulting in poor applicability of some detection devices and causing waste of costs to a certain extent. For some detection devices to adapt to more types of split conductors, the spacing between the ray machine and the imaging plate may be large, but this setting also increases the spacing between the ray machine, the imaging plate, and the wire. Under extreme conditions, the imaging plate also needs to be larger, otherwise it cannot fully form an image. However, the detection device itself is heavy, and an overly large imaging plate will increase the overall mass, bringing risks to the hoisting of the unmanned aerial vehicle.

[0014] The horizontal spacing between the ray machine and the imaging plate of the present utility model is adjustable, and it can adapt to various types of split conductors.

[0015] Furthermore, the frame includes a cross frame and longitudinal frames A and B respectively connected to both ends of the cross frame. The cross frame is connected to the walking wheels;

[0016] The ray machine is installed on the longitudinal frame A, and the imaging plate is installed on the longitudinal frame B.

[0017] The frame of this embodiment is divided into a cross frame and two longitudinal frames. Both ends of the cross frame protrude beyond the transmission wire. The two longitudinal frames are respectively connected to the two ends of the cross frame, so that the ray machine and the imaging plate located on the longitudinal frames are also located on the outer side surface of the wire, facilitating the detection of the tension clamps on each wire.

[0018] Furthermore, the ray machine is rotatably connected to the longitudinal frame A, and the imaging plate can longitudinally slide on the longitudinal frame B. The rays emitted by the emitting end of the ray machine penetrate the tension clamp and project onto the imaging plate.

[0019] The ray machine is rotatably connected to the longitudinal frame A, so that the ray machine can rotate relative to the longitudinal frame in the vertical plane, which is used to detect the tension clamps on transmission lines at different heights.

[0020] After the ray machine rotates to detect the strain clamps of transmission lines at different heights, in order to enable the detection results to be completely displayed on the imaging plate, the imaging plate can slide longitudinally, so that this detection device can adapt to the strain clamps of cables at various heights without overly increasing the area of the imaging plate, and to ensure the overall volume and mass of the device to the greatest extent.

[0021] Furthermore, both ends of the cross frame are provided with telescopic parts, and the telescopic parts can be telescoped along the extending direction of the cross frame.

[0022] Both ends of the cross frame are telescopic, so that the horizontal distance between the longitudinal frames connected to the ends of the cross frame changes, and the distance between the imaging plate on the longitudinal frame and the ray machine can be variable, which is used to adapt to different conductor widths.

[0023] Furthermore, the telescopic part is slidably connected to the cross frame, and the telescopic part can slide relative to the end of the cross frame and adjust the length of the telescopic part extending out of the cross frame;

[0024] The traveling wheels are installed on the telescopic part and can move along with the telescopic part.

[0025] To ensure that the traveling wheels can still be on the cable after the cross frame is telescoped, the traveling wheels are connected to the telescopic parts of the cross frame and change their positions along with the telescoping of the cross frame.

[0026] Furthermore, a connecting piece is provided between the traveling wheel and the telescopic part, the traveling wheel is rotatably connected to the connecting piece, and the connecting piece is hingedly connected to the telescopic part.

[0027] Since the strain clamp is clamped and fixed outside the cable, during the process of the traveling wheel moving from the cable to the strain clamp, the height of the traveling wheel changes. At this time, the connecting piece is hinged to the telescopic part to adapt to the position change of the traveling wheel and maintain the stability of the detection device relative to the cable during this process.

[0028] During the process of the traveling wheel entering the strain clamp, there is a height change. If the traveling wheel is directly connected to the cross frame, the overall stability of the device is poor and it is easy to lose balance and fall. In this solution, the traveling wheel is connected to the cross frame through a connecting piece, so that when the traveling wheel bumps, the main structure of the detection device will not be significantly affected.

[0029] The traveling wheel is rotatably connected to the connecting piece, so that the traveling wheel is not affected by the connecting piece during the process of rotating and shifting, ensuring that this detection device can walk normally.

[0030] Furthermore, a shock-absorbing rod is also connected between the connecting piece and the telescopic part;

[0031] The shock-absorbing rod includes a telescopic rod and a spring. The spring is sleeved on the telescopic rod, and both ends of the spring are respectively connected to both ends of the telescopic rod. One end of the telescopic rod is connected to the telescopic part, and the other end of the telescopic rod is connected to the connecting piece.

[0032] To prevent the walking wheels from jolting due to sudden height changes, a shock-absorbing rod is provided between the connecting piece and the telescopic part for shock absorption to enhance the stability of the device during walking.

[0033] In this embodiment, the shock-absorbing rod adopts a combined design of a telescopic rod and a spring for shock absorption, which can effectively absorb and buffer external impact or vibration energy, and improve the stability and adaptability of the structure.

[0034] In summary, the present utility model has the following beneficial effects compared with the prior art:

[0035] 1. The horizontal distance between the ray machine and the imaging plate is adjustable to adapt to different wire widths;

[0036] 2. The walking wheels are connected to the cross frame through the connecting piece, and a shock-absorbing rod is provided between the cross frame and the connecting piece, so that when the walking wheels encounter uneven cables or enter and exit the strain clamp, the overall structure is relatively stable and smooth.

[0042] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments and descriptions thereof of the present utility model are only used to explain the present utility model and do not constitute a limitation to the present utility model.

[0043] Embodiment:

[0044] As Figures 1 - 3 shown, this embodiment relates to a tension clamp detection device for multi - split conductors in the technical field of tension clamp detection, including a frame. A traveling wheel 1 for supporting the frame is provided on the frame. An X - ray machine 6 and an imaging plate 4 are also installed on the frame. There is a space between the X - ray machine 6 and the imaging plate 4 that can accommodate the tension clamp, and the horizontal distance between the X - ray machine 6 and the imaging plate 4 is adjustable.

[0045] The traveling wheel 1 is used to walk along the conductor, driving this detection device to reach or leave the detection position.

[0046] The frame is used to provide installation positions for the X - ray machine 6 and the imaging plate 4.

[0047] The frame is covered on the outer side of the conductor. The X - ray machine 6 and the imaging plate 4 installed on the frame are respectively located on two sides of the frame, so the X - ray machine 6 and the imaging plate 4 are respectively located on two opposite outer sides of the conductor. The X - ray machine 6 can emit rays to irradiate the tension clamp in the middle and project onto the imaging plate 4, which is used to detect the tension clamp on the transmission conductor.

[0048] When this utility model is specifically implemented, the detection device is lifted to the transmission conductor by a drone. Then, the traveling wheel 1 is placed on the transmission conductor. The frame is driven by the traveling wheel 1 to carry the X - ray machine 6 and the imaging plate 4 to move to the position of the tension clamp to detect the tension clamp.

[0049] Since the conductor spacing of multi - split conductors varies with different voltage levels, conductor specifications, and transmission requirements. In the prior art, the horizontal distance between the X - ray machine 6 and the imaging plate 4 in the detection device cannot be adjusted, resulting in poor applicability of some detection devices and causing a certain degree of waste of costs. And for some detection devices to adapt to more types of split conductors, the distance between the X - ray machine 6 and the imaging plate 4 may be large. However, this setting also increases the distance between the X - ray machine 6, the imaging plate 4 and the conductor. Then, under extreme conditions, the imaging plate 4 also needs to be larger, otherwise complete imaging cannot be achieved. But the detection device itself is heavy, and an overly large imaging plate 4 will increase the overall mass, bringing risks to the lifting by the drone.

[0050] The horizontal distance between the X - ray machine 6 and the imaging plate 4 of this utility model is adjustable, which can adapt to the ray detection of tension clamps of various different types of split conductors. And in terms of imaging quality, ray detection can be completed in a better way. Specifically:

[0051] Regarding the adjustable horizontal spacing, it can be used to address the following: In the prior art, common bundled conductors include, for example, four-bundle conductors and six-bundle conductors. The spacing between the conductors may be 450 mm, 500 mm or other distance dimensions. To enable this device to be applicable to the width requirements of different detection positions and at the same time make the ray machine 6 and the imaging plate 4 have a relatively close distance relative to the tension clamp to be detected for the sake of imaging quality, it is necessary to adjust the horizontal spacing to match the relative positions of the ray machine 6, the imaging plate 4, and the tension clamp. For example, when the ray machine 6 and the imaging plate 4 are carried by the corresponding longitudinal frames on the frame, the frame formed by the cross frame 2, the longitudinal frame B3, and the longitudinal frame A5 straddles the bundled conductors as a whole, that is, each conductor is accommodated within the space. At this time, the horizontal spacing is adjusted to adapt to the width of the bundled conductors in the transverse direction, so that the horizontal spacing meets the requirements of high-quality detection.

[0052] Furthermore, especially for six-bundle conductors, after this device is supported on the top two conductors by the walking wheels 1, the tension clamps to be detected on one side are distributed in different spatial positions. To adapt to the detection requirements of tension clamps in different positions, a preferred implementation method is that the imaging plate completes height adjustment through a hoisting mechanism (if the height adjustment method is not adopted, a larger area of imaging plate needs to be set, which will increase the weight of this device and affect the stability of this device under wind load). The ray machine 6 realizes the adjustment of the emission end orientation by rotating the drive motor. For the tension clamps to be detected on each side of the six-bundle conductors, the ray machine 6 should be set on the opposite side of this side. To avoid the outermost conductor of the bundled conductors affecting the rotation of the ray machine 6 and at the same time make the ray machine 6 have a relatively close position to the tension clamp to be detected. If the conductors on one side of the six-bundle conductors are defined as conductor No. 1, conductor No. 2, and conductor No. 3 from top to bottom respectively, generally conductor No. 1 is directly above conductor No. 3, and conductor No. 2 is outside conductor No. 1 or conductor No. 3. At this time, the longitudinal frame can pass through the space between conductor No. 1 and conductor No. 2. Under such application, the width between the longitudinal frames and the spacing of the walking wheels can be adjusted by sliding the corresponding longitudinal frames along the width direction of the cross frame: The upper ends of each longitudinal frame are slidably connected to the cross frame. After sliding in place, the longitudinal frame and the cross frame are locked to each other. The walking wheels 1 are fixed on the longitudinal frame, and the imaging plate 4 and the ray machine 6 are also fixed on the corresponding longitudinal frames. The above horizontal spacing adjustment is achieved by the longitudinal frame sliding along the cross frame. When detecting the tension clamps on conductor No. 1 and conductor No. 3, the walking wheels 1 are supported on conductor No. 1, the longitudinal frame where the imaging plate 4 is set is located in the space between conductor No. 1 and conductor No. 2, and the longitudinal frame where the ray machine 6 is set is located in the space between conductor No. 1 and conductor No. 2 on the opposite side. When detecting conductor No. 2, the walking wheels 1 are supported on conductor No. 1, the longitudinal frame where the imaging plate 4 is set is located outside conductor No. 2, and the longitudinal frame where the ray machine 6 is set is located in the space between conductor No. 1 and conductor No. 2 on the opposite side.

[0053] Further, the frame includes a cross frame 2, and longitudinal frames A5 and B3 respectively connected to both ends of the cross frame 2. The cross frame 2 is connected to the traveling wheels 1;

[0054] The ray machine 6 is installed on the longitudinal frame A5, and the imaging plate 4 is installed on the longitudinal frame B3.

[0055] The frame of this embodiment is divided into a cross frame and two longitudinal frames, and both ends of the cross frame protrude from the transmission wires. By connecting the two longitudinal frames to the two ends of the cross frame 2 respectively, the ray machine 6 and the imaging plate 4 located on the longitudinal frames are also on the outer side of the wires, facilitating the detection of the strain clamps on each wire.

[0056] As an implementable solution of the above solution, gaps are left between both longitudinal frames and the wires, which will not damage the wires due to the displacement of the monitoring device and avoid short circuits caused by accidental contact.

[0057] Further, the ray machine 6 is rotatably connected to the longitudinal frame A5, the imaging plate 4 can slide longitudinally on the longitudinal frame B3, and the rays emitted from the emitting end of the ray machine 6 penetrate through the strain clamp and are projected onto the imaging plate 4.

[0058] The ray machine 6 is rotatably connected to the longitudinal frame A5, so the ray machine 6 can rotate relative to the longitudinal frame in the vertical plane for detecting the strain clamps on transmission lines at different heights.

[0059] After the ray machine 6 rotates to detect the strain clamps of transmission lines at different heights, in order to make the detection results fully displayed on the imaging plate 4, the imaging plate 4 can slide longitudinally, enabling this detection device to adapt to the strain clamps of cables at various heights without excessively increasing the area of the imaging plate 4, and ensuring the overall volume and mass of the device to the greatest extent.

[0060] As an implementable solution of the above solution, in order to enable the orientation of the ray machine 6 to adapt to the strain clamps at different positions, the ray machine 6 is rotatably connected to the longitudinal frame A5, and a driving motor is also installed on the longitudinal frame A5. The axis of the rotor of this driving motor is parallel to the width direction of the side frame, and the housing of the ray machine 6 is fixed to the end of the rotor. This driving motor is used to rotate the ray machine 6 to emit rays onto the strain clamp.

[0061] As an alternative to the implementable solution of the above solution, the ray machine 6 is rotated by using a joint servo motor or other motors that can feedback specific positions.

[0062] As an alternative to the implementable solution of the above solution, the ray machine 6 is rotated by the cooperation of a general motor and a sensor.

[0063] As an implementable solution of the above solution, the imaging plate 4 is fixed on the connecting frame, the connecting frame is longitudinally slidably connected to the longitudinal frame B3, the connecting frame can carry the imaging plate 4 and slide up and down relative to the longitudinal frame B3, and a hoisting mechanism is provided on the longitudinal frame B3. A pulling rope is wound around the drum of the hoisting mechanism, and the lower end of the pulling rope is connected to the connecting frame. When the drum of the hoisting mechanism rotates, the pulling rope on the drum drives the connecting plate and carries the imaging plate 4 to move longitudinally. The structure of this embodiment is simple, beneficial to reducing the weight of the device, and has high reliability.

[0064] As an alternative solution of the above solution, the ray machine 6 can move horizontally and longitudinally relative to the longitudinal frame A5, and the imaging plate 4 can move horizontally and longitudinally relative to the longitudinal frame B3. Make the connecting lines between the ray machine 6, the imaging plate 4 and the strain clamps on each cable all be horizontal line segments. After the walking wheels 1 are installed on the wire, the detection of the strain clamps on all the wires in this part can be completed.

[0065] As an implementation manner of the alternative solution, the size of the imaging plate 4 is just enough to completely display the detection result. Further, telescopic parts 7 are provided at both ends of the cross frame 2, and the telescopic parts 7 can all telescope along the extending direction of the cross frame 2.

[0066] Both ends of the cross frame are telescopic, so that the horizontal distance between the longitudinal frames connected to the ends of the cross frame changes, and the distance between the imaging plate 4 and the ray machine 6 located on the longitudinal frame is variable, which is used to adapt to different wire widths.

[0067] As an implementable solution of the above solution, the telescopic part 7 can be telescoped by means of electric, manual, hydraulic push, etc.

[0068] As an implementable solution of the above solution, a number of stable nodes are provided at the end of the cross frame 2 along the extending direction of the cross frame 2. The telescopic part 7 is connected to the cross frame 2 through one of the stable nodes. If it is a side four-split, the telescopic part 7 is retracted to a stable node far from the end of the cross frame 2 to adapt to the wire width. If it is a side six-split, it extends to a stable node close to the end of the cross frame 2, and then the detection device is hoisted onto the wire by a drone for detection.

[0069] Further, the telescopic part 7 is slidably connected to the cross frame 2, and the telescopic part 7 can slide relative to the end of the cross frame 2 and adjust the length of the telescopic part 7 extending out of the cross frame 2;

[0070] The walking wheels 1 are installed on the telescopic part 7 and can move along with the telescopic part 7.

[0071] To ensure that the walking wheels 1 can still be on the cable after the cross frame is telescoped, the walking wheels 1 are connected to the telescopic part 7 of the cross frame and change their positions together with the telescoping of the cross frame 2.

[0072] Further, a connecting member 9 is provided between the traveling wheel 1 and the telescopic portion 7. The traveling wheel 1 is rotatably connected to the connecting member 9, and the connecting member 9 is hinged to the telescopic portion 7.

[0073] Since the strain clamp is clamped and fixed outside the cable, during the process of the traveling wheel 1 moving from the cable to the strain clamp, there is a change in the height of the traveling wheel 1. At this time, the connecting member 9 is hinged to the telescopic portion 7 to adapt to the position change of the traveling wheel 1 and maintain the stability of the detection device relative to the cable during this process.

[0074] During the process of the traveling wheel 1 entering the strain clamp, there is a change in height. If the traveling wheel 1 is directly connected to the cross frame 2, the overall stability of the device is poor and it is easy to lose balance and fall. In this solution, the traveling wheel 1 is connected to the cross frame 2 through the connecting member 9, so when the traveling wheel 1 bumps, the main structure of the detection device will not be significantly affected.

[0075] The traveling wheel 1 is rotatably connected to the connecting member 9, so the traveling wheel 1 is not affected by the connecting member 9 during the process of rotating and shifting, ensuring that the detection device can walk normally.

[0076] Further, a shock-absorbing rod 8 is also connected between the connecting member 9 and the telescopic portion 7;

[0077] The shock-absorbing rod 8 includes a telescopic rod and a spring. The spring is sleeved on the telescopic rod, and both ends of the spring are respectively connected to both ends of the telescopic rod. One end of the telescopic rod is connected to the telescopic portion 7, and the other end of the telescopic rod is connected to the connecting member 9.

[0078] In order to prevent the traveling wheel 1 from bumping due to a sudden change in height, a shock-absorbing rod 8 is provided between the connecting member 9 and the telescopic portion 7 for shock absorption to enhance the stability during the walking process of the device.

[0079] In this embodiment, the shock-absorbing rod 8 adopts a combined design of a telescopic rod and a spring for shock absorption, which can effectively absorb and buffer external impact or vibration energy, and improve the stability and adaptability of the structure.

[0080] As an alternative to the above solution, the surface of the traveling wheel 1 is wrapped with a buffer cushion layer.

[0081] As an alternative to the above solution, other shock-absorbing structures can be used to replace the shock-absorbing rod 8 in the above embodiment.

[0082] As an alternative to the above solution, the driving wheel 1 is built-in with a power device and can move autonomously without continuous external force pushing. In this embodiment, the driving wheel 1 is a drive wheel that can provide traction force. Compared with other methods of moving the device from the cable into the strain clamp, this embodiment enables the driving wheel 1 to enter the strain clamp easily and stably. At the same time, the drive wheel can respond to the braking instruction faster, which is convenient for accurately controlling the detection position of this detection device.

[0083] When the above solution is used for the strain clamps on four-conductor or six-conductor split conductors, the detection device is hoisted onto the conductor. First, the strain clamps on one side conductor with longitudinal distribution are detected. Then, the detection device is re-hoisted by the unmanned aerial vehicle. After turning the detection device around, it is re-hoisted onto the conductor to detect the strain clamps on the other side conductor.

[0084] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
