Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage cable detection, and particularly relates to a suspension protection device for surface detection of high-voltage cables. Background Art

[0002] A high-voltage cable is a cable used to transmit a relatively high voltage, and the erection of high-voltage cables is used to meet the power consumption needs of the user side.

[0003] During the use of high-voltage cables, it is often necessary to detect and maintain the high-voltage cables to ensure that the high-voltage cables maintain normal power transmission during operation through regular detection and maintenance. During the overhaul process, the operator needs to climb from the cable tower pole to the relatively high cable and detect along the cable to troubleshoot.

[0004] However, in the actual working process, due to the very high erection height of the cable, the risk is very high for the operator during the process of crawling and detecting along the cable, especially for the cables spanning above rivers and canyons.

[0005] At the same time, during the overhaul process, the environment has a great impact on the overhaul and detection. For example, during rainy days, the high-voltage cable discharges with the air, resulting in a very high risk during the detection process. At the same time, the wind also has a great impact on the detection. When the wind is strong, the cable sways violently under the action of the wind, causing the detection personnel walking on the cable to be unable to move stably on the cable. Once the operator falls from the cable, although the operator is hung on the cable by a hook, the suspended operator is still very dangerous. Content of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a suspension protection device for surface detection of high-voltage cables.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A suspension protection device for surface detection of high-voltage cables includes a walking and detecting mechanism that suspends and walks on the high-voltage cable;

[0009] The walking and detecting mechanism includes a walking frame, and clamping and walking components are respectively assembled and connected at both ends of the walking frame;

[0010] The clamping and walking components include an upper clamping wheel and a lower clamping wheel that clamp on the cable;

[0015] After the detection is completed, the upper clamping wheel and the lower clamping wheel move away from each other and disengage from the cable;

[0016] A detection mechanism is assembled and connected to the top of the traveling frame.

[0017] Preferably, a hinge interface is provided on the wheel frame, the telescopic seat includes hinge parts that are arranged at intervals up and down at the inner end, and the hinge parts are respectively hinged in the hinge interfaces of the corresponding wheel frames;

[0018] The output shaft of the rotating motor is fixedly assembled at the inner end position of the side wall of the wheel frame, and the rotating motor is fixedly assembled on the outer side wall of the telescopic seat through a motor connection seat.

[0019] Preferably, a clamping groove for clamping the cable is provided on the clamping wheel.

[0030] The utility model has the following beneficial effects:

[0031] 1. During the working process, under normal circumstances, the rotating motor keeps the upper clamping wheel and the lower clamping wheel in an open posture. When it is necessary to hang and walk on the cable for detection, driven by the rotating motor, the upper clamping wheel and the lower clamping wheel close until the clamping wheel is locked onto the cable.

[0033] 2. During the working process, when walking and detecting, first, the electric push rod pushes the telescopic seat to carry the above-mentioned wheel frame and the clamping wheel close to the cable, and clamps the cable in the above-mentioned manner. By this method, the extension distance of the wheel frame and the clamping wheel can be adjusted according to the distance between the two sides of the cable, so as to facilitate clamping the cable. After inspection, with the cooperation of the return spring, the wheel frame is quickly retracted, which is convenient for carrying. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiment 1

[0045] As Figures 1-5 shown, a suspension protection device for surface detection of high-voltage cables includes a walking detection mechanism that walks and detects on the high-voltage cable. The walking detection mechanism is used to replace manual detection.

[0046] The specific structure of the walking detection mechanism is as follows:

[0047] The walking detection mechanism includes a walking frame 1, and clamping and walking components are respectively assembled and connected at both ends of the walking frame 1; specifically, the clamping and walking components include an upper clamping wheel and a lower clamping wheel that clamp on the cable.

[0048] Specifically, both the upper clamping wheel and the lower clamping wheel include a wheel frame 51, and the wheel frame 51 is equipped with a clamping wheel 53. Specifically, the clamping wheel 53 is rotatably connected to the wheel frame 51, and a travel motor 52 for driving the clamping wheel 53 to rotate is installed on the wheel frame 51. Specifically, the motor body of the travel motor 52 is fixedly installed on the wheel frame 51, and its output shaft is installed on the clamping wheel 53. Driven by the travel motor 52, the clamping wheel 53 is clamped on the cable to form a friction driving force, so that walking detection in a suspended manner on the cable is realized in this way, thereby replacing the transmission of human climbing walking detection, and protecting maintenance personnel in a highly safe manner.

[0049] Specifically, the upper clamping wheel 53 and the lower clamping wheel 53 are respectively hinged with a telescopic seat 2; the telescopic seat 2 is installed on the walking frame 1. The hinge method is: a hinge port is provided on the wheel frame 51, and the telescopic seat 2 includes a hinge portion 21 with an inner end spaced up and down, and the hinge portion 21 is respectively hinged in the hinge port of the corresponding wheel frame 51. The specific hinge method is: a hinge shaft is fixedly connected to the hinge portion 21, and the hinge shaft is hinged in the hinge port.

[0050] Meanwhile, the wheel frame 51 is equipped with a rotary motor 54 for driving the wheel frame 51 to flip. Specifically, the output shaft of the rotary motor 54 is fixedly assembled at the inner end position of the wheel frame 51 side wall, and the rotary motor 54 is fixedly assembled on the outer side wall of the telescopic seat 2 through a motor connecting seat 541.

[0051] Under normal circumstances during operation, the rotating motor 54 puts the upper clamping wheel 53 and the lower clamping wheel 53 into an open position. When it is necessary to suspend and walk on the cable for inspection, the upper clamping wheel 53 and the lower clamping wheel 53 are driven by the rotating motor 54 to close until the clamping wheel 53 is locked to the cable. During this process, the cable is locked in the clamping groove opened on the clamping wheel 53.

[0052] After clamping, the walking motor 52 works, and with the cooperation of the upper and lower clamping wheels 53, the cable can be walked on the cable by relying on friction power. During the walking process, the cable can be inspected. The above method can suspend the walking cable in a protective manner, solving the defects of high risk factor of manual cable climbing and operation affected by weather. This method can realize long-distance walking inspection on the cable.

[0053] After the detection is completed, the upper clamping wheel 53 and the lower clamping wheel 53 move away from each other and detach from the cable.

[0054] Example 2

[0055] like Figures 1-5As shown in the figure, in this embodiment, based on the structure of Embodiment 1, the telescopic seat 2 further includes a U-shaped connecting portion integrally formed between the hinge portions 21. End seats 11 are integrally formed at both ends of the walking frame 1. The end seats 11 and the telescopic seat 2 are assembled and connected through a telescopic structure.

[0056] Specifically, the telescopic structure includes several sliding rods 3 fixedly connected to the U-shaped connecting portion; the sliding rods 3 are slidably connected to the end seats 11 (a retaining cap is fixedly connected to the inner end of the sliding rod 3), and the telescopic structure further includes an electric push rod 4 fixedly assembled on the end seats 11 (where the electric push rod 4 is a conventional electric telescopic rod disclosed in the prior art), and the pushing end of the electric push rod 4 is fixedly installed on the U-shaped connecting portion.

[0057] A return spring 31 is sleeved on the sliding rod 3, and both ends of the return spring 31 are fixedly connected to the U-shaped connecting portion and the end seat 11 respectively. Specifically, the return spring 31 is sleeved on some of the sliding rods 3 to reduce the pushing resistance of the electric push rod 4 for pushing the telescopic seat 2.

[0058] During the working process, when detecting the walking, first, the electric push rod 4 pushes the telescopic seat 2 to carry the wheel frame 51 and the clamping wheel 53 close to the cable, and clamps the cable in the above-mentioned manner. By this method, the extension distance of the wheel frame 51 and the clamping wheel 53 can be adjusted according to the distance between the cables on both sides, so as to facilitate clamping the cable.

[0059] Embodiment 3

[0060] As Figures 1-5 shown, based on the structure of Embodiment 2, a detection mechanism is assembled and connected to the top of the walking frame 1 in this embodiment. Specifically, the detection mechanism includes a rotating arm 61 rotatably connected to the walking frame 1; specifically, a driving motor 64 for driving the rotating arm 61 is installed at the bottom of the walking frame 1, the output shaft of the driving motor 64 is rotatably connected to the walking frame 1 and fixed on the rotating arm 61. The motor is fastened to the bottom of the walking frame 1 by means of bolts.

[0061] Detection probes 62 are respectively assembled and connected to both ends of the rotating arm 61 (the detection probes 62 are fixedly installed on the rotating arm 61 through probe connecting rods 62); the detection probes 62 are detection sensors often used in the existing power detection process, such as the detection probe 62 is an infrared temperature measurement probe. The temperature of the cable is detected through the infrared temperature measurement probe, such as for finding the cable parts with abnormal temperature.

[0062] Embodiment 4

[0063] As Figures 1-5As shown, on the basis of the structure of Embodiment 3, in order to improve the safety during walking detection, the above-mentioned walking detection mechanism, including the walking frame 1, the clamping wheel 53, the wheel frame 51, the telescopic seat 2, etc., are all made of materials with high insulation, such as insulating plastic materials.

[0064] At the same time, in the conventional manner, motor insulation sleeves (not shown in the figure) are installed on all motors to protect the motors.

[0065] In the same way as the existing method, a mobile power source (not shown in the figure) is installed at the bottom of the walking frame 1, and in the same existing electrical connection relationship, the motor and the sensor are powered by the mobile power source to work.

[0066] In the same way as the existing method, the detection probe 62 uses a detection sensor commonly used in the power detection process, such as an infrared temperature measurement probe. In order to transmit the detection data to the background, the detection sensor uses a sensor that can wirelessly transmit detection signals as disclosed in the prior art.

[0067] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
