Description

Technical Field

[0001] The present invention relates to the technical field of high-altitude cable measurement, and particularly relates to an environment-friendly high-altitude cable measurement device. Background Art

[0002] After being erected, high-altitude cables will gradually age over time, temperature, meteorological conditions, etc., and grid personnel need to perform regular maintenance. Measuring their curvature, surface damage degree, deformation degree, and temperature of each part has always been a difficult problem in the electrical technology field. At present, the measurement of high-altitude cables usually adopts manual methods, and grid personnel usually walk along long-distance cables to achieve meticulous measurement and inspection; there is also a method of using drones for line patrol, but this method is not only affected by high-altitude temperature and light, resulting in inaccurate measurement, but also affected by meteorological conditions, resulting in inability to measure.

[0003] The Chinese patent document with the application publication number CN 111929537 A discloses a self-propelled high-altitude cable damage detection device and detection method. However, the overall structure of this device is a long cylindrical structure. When walking on a high-altitude cable, since the front and rear wheels are in a straight line, it will inevitably cause the effect of "passively straightening" the bent cable. At least, the measurement (detection) result will have an error, and at worst, it will get stuck at the bent part of the high-altitude cable and unable to move forward. Moreover, its belt drive assembly method is only limited to a single cable. When there is a large area and thick dust and stains on cables with different diameters, the rollers are very likely to get stuck; and for the added existing sensor devices, due to the unreasonable layout, the detection types are not rich enough.

[0004] For the immature designs and problems to be solved in the prior art, there is an urgent need for an environment-friendly device that can adapt to different diameters of high-altitude cables and will not affect the curvature of the cables, and can also monitor parameters such as temperature, curvature, and wind direction of each part of the high-altitude cable in real time.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] As Figures 1 to 9 shown, the present invention includes two main bodies 1 connected by a front and rear link mechanism 10. The main body 1 is composed of an upper main body 2 and a lower main body 3 which are fitted together to facilitate the operator to safely fasten the device to the cable at high altitude. A "pin" - shaped channel is provided in the middle of the upper main body 2, and a channel in the shape of an inverted "pin" of the same size is provided at the corresponding position of the lower main body 3. The two channels penetrate through the front and rear to jointly form a cable channel 4. A transverse transmission mechanism 7 and a longitudinal transmission mechanism 8 capable of clamping the high - altitude cable 20 are installed in the cable channel 4.

[0035] The outer shape of the upper main body 2 is a symmetric figure with two upper corners of a cuboid cut off. Solar panels 17 are provided on the three outer side surfaces above, which can supply solar power to the device in all directions. Two inclination sensors 15 and a control module 16 are installed in the inverted "concave" - shaped groove above the cable channel 4 of the upper main body 2. The inclination sensors 15 can monitor the horizontal and vertical degrees of the device in real time. The control module 16 is connected to all the electrical components of the device. It is a conventional processor device that controls the operation of the entire device. At the same time, a wireless module is built into the control module 16, which can communicate with a remote host computer.

[0036] An energy storage mechanism 9 is installed in the lower main body 3. The energy storage mechanism 9 includes a cavity that runs through the left and right inside the lower main body. A lead - acid battery 901 is fixed at the middle position inside the cavity. The lead - acid battery 901 is less likely to catch fire and is heavier than a conventional lithium battery. Located in the lower half of the main body 1, the counterweight block can be omitted and the overall center of gravity of the device can be moved down to the exact bottom. The lead - acid battery 901 is fixed by two fixing blocks 902 on the left and right. Concave - shaped doors 903 are provided at the left and right openings of the cavity to reduce wind resistance and facilitate the operator to open and close for replacing the lead - acid battery 901.

[0037] Turbofans 5 are symmetrically installed at positions of the upper main body 2 and the lower main body 3 near the cable channel 4, and the turbofans 5 are connected to the motor inside the main body 1; each turbofan 5 is located inside the main body 1 and fixed on the rotating shaft of a conventional motor, and a motor is arranged between the front and rear turbofans 5, which can be used to charge the device by driving the rotation of the motor shaft when the device is descending, and can also provide partial power for lifting when the device is ascending; an insect-proof filter is arranged on the outside of the turbofan 5; a baffle b19 is arranged on the outer edge of the inverted "concave" shaped groove to protect the control module 16.

[0038] The cable channel 4 is the inner wall portion of the main body 1, and a pair of transverse transmission mechanisms 7 are installed on both sides of the left and right inner walls of the cable channel 4 of the upper main body 2 and the lower main body 3; Figure 3 The horizontal transmission mechanism 7 is relatively set up on the left and right, including a horizontal wheel 702 in contact with the aerial cable 20, the horizontal wheel 702 is a concave surface from the outer edge to the center, and a circular arc convex head 703 is installed in the center. This layout and shape can adapt to aerial cables of different specifications (i.e. diameters). The horizontal wheel 702 is fixed on the horizontal controller 701 through a rotating shaft. A motor is installed inside the horizontal controller 701. A distance sensor 704 is installed in a groove set in the center of the bottom of the shell. Circular grooves are set at the four corners of the bottom of the shell, and a horizontal spring 708 is installed in the circular groove. The horizontal controller 701 is connected to the horizontal controller 701 through a rotating shaft. Four transverse springs 708 are sleeved in the circular grooves corresponding to the transverse square tubes 707, and a temperature sensor 14 is also installed at the top center position of the two left and right transverse square tubes 707 below. When the device moves on the aerial cable 20, it can monitor the temperature of the cable surface in real time; the transverse slide rail 705 installed on the shell of the transverse controller 701 cooperates with the transverse slider 706 installed in the transverse square tube 707 to ensure that the transverse controller 701 can slide within a certain range; all the transverse springs 708 are always in a compressed state regardless of whether they are in contact with the aerial cable 20 to ensure that they can be tightly attached to the aerial cable 20 on the left and right.

[0039] Likewise, see Figure 4The longitudinal transmission mechanism 8 has a pair and is relatively installed at the top and bottom of the cable channel 4. The longitudinal transmission mechanism 8 includes longitudinal wheels 802 installed on the longitudinal controllers 801 on both sides through a rotating shaft. Each longitudinal controller 801 is connected to the bottom of the longitudinal square tube 805 through a longitudinal spring 806 in two circular grooves at the bottom of its shell. The longitudinal controller 801 cooperates with the longitudinal slide rail 804 on the inner wall of the longitudinal square tube 805 through a longitudinal slider 803 installed on the side. A motor is installed inside the longitudinal controller 801, and a distance sensor 704 is also installed in the groove set in the center of the bottom of its shell. When encountering pits or protrusions on the cable, the change in distance can cause the sensor to change; the longitudinal spring 806 is always in a compressed state to ensure that the longitudinal wheel 802 can be tightly attached to the upper and lower sides of the aerial cable 20.

[0040] The above-mentioned two transverse transmission mechanisms 7 and four longitudinal transmission mechanisms 8, when the device slides freely on the aerial cable 20, the transverse wheels 702 and the longitudinal wheels 802 rotate, and the kinetic energy is recovered by the motor to supply power to the lead-acid battery 901 in the device; when the device falls to the lowest point of the aerial cable 20, reverse energy is supplied to drive the rotation of the transverse wheels 702 and the longitudinal wheels 802 for its ascending movement.

[0041] like Figure 5 , Figure 6 As shown, the front and rear connecting rod mechanism 10 includes a rear fixed block 1006 fixed on the front end surface of the rear main body 1 and a front fixed block 1007 fixed on the rear end surface of the front main body 1, an angle sensor a1003 arranged on the rear fixed block 1006 is rotationally connected to the connecting rod a1001, and an angle sensor c1005 arranged on the front fixed block 1007 is rotationally connected to the connecting rod b1002, and an angle sensor b1004 is fixed to the other end of the connecting rod a1001, and the other end of the connecting rod b1002 is rotationally connected to the angle sensor b1004, and the three angle sensors are all connected to the control module 16 and the lead-acid battery 901 in the main body 1 through conventional wires, and the three angle sensors and the two freely rotating connecting rods can determine the positional relationship between the front and rear main bodies through the included angle calculated by the control module 16, and then measure the bending degree of each part of the aerial cable 20, that is, the curvature.

[0042] The length of the connecting rod a1001 is longer than that of the connecting rod b1002 to avoid mutual collision between the front and rear bodies as much as possible; anti-collision sponges 11 are installed on the top of the rear fixing block 1006 and the front fixing block 1007, which will play a buffering role even if a collision occurs.

[0043] like Figure 8 , Fig. 9As shown, the connecting surfaces at both ends of the bottom of the upper main body 2 are provided with wire plugs 12, and the connecting surfaces at both ends of the top of the lower main body 3 are provided with wire jacks 13 that match the wire plugs 12, and the upper main body 2 and the lower main body 3 are fixed together by bolt fixing blocks on the side; this design can not only perfectly fit the upper main body 2 and the lower main body 3, but also only after the two are combined with each other can they be connected into a pathway, and the lead-acid battery 901 will supply or store energy.

[0044] A wind direction sensor 6 is inverted at the bottom of the lower body 3. The signal after the wind direction sensor 6 needs to be corrected after the control module 16 inverts the signal to obtain an accurate result; the upper body 2 and the lower body 3 are fixed by bolt fixing blocks on the side.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
