DETAILED DESCRIPTION

[0026] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0027] Example 1: A portable cable detection device, such as Figures 1-8 As shown, it includes a holding frame 1, an arc-shaped plate 2, a spring telescopic plate 3, a moving wheel 4 and a latch 10; a storage battery is provided on the holding frame 1; two symmetrically arranged arc-shaped plates 2 are rotatably connected to the holding frame 1; two symmetrically arranged spring telescopic plates 3 are respectively fixed to the two arc-shaped plates 2, and the spring telescopic plates 3 are composed of a storage portion and a telescopic end, and a telescopic spring is provided between the storage portion and the telescopic end; each telescopic end of the spring telescopic plate 3 is respectively fixed to a moving wheel 4; a latch 10 is inserted between the two arc-shaped plates 2;

[0028] It also includes a wireless camera 5, an arc-shaped electric slide rail 6, an arc-shaped electric slider 7, an electric push rod 8 and an extrusion plate 9; each of the two arc-shaped plates 2 is fixed with an arc-shaped electric slide rail 6; each of the arc-shaped electric slide rails 6 is fixed with two wireless cameras 5; each of the arc-shaped electric slide rails 6 is slidably connected with an arc-shaped electric slider 7; each of the two arc-shaped electric sliders 7 is fixed with an electric push rod 8; each of the electric push rods 8 is fixed with an extrusion plate 9 at its telescopic end; a pressure sensor is provided between the telescopic end of each electric push rod 8 and the extrusion plate 9.

[0029] In order to facilitate insertion into the mounting hole of the arc-shaped plate 2, the lower portion of the latch 10 is configured to be conical.

[0030] It also includes an arc-shaped plate 21; an arc-shaped plate 21 is welded to each of the two arc-shaped plates 2 on one side away from the arc-shaped electric slide rail 6.

[0031] It also includes an arc-shaped baffle 22; each arc-shaped plate 21 and each arc-shaped electric slide rail 6 are respectively welded with an arc-shaped baffle 22.

[0032] It also includes an arc-shaped flexible plate 23 ; each arc-shaped baffle 22 is fixed with an arc-shaped flexible plate 23 .

[0033] It also includes an electrically controlled heating plate 24 ; each arc-shaped baffle 22 is fixedly connected with an electrically controlled heating plate 24 .

[0034] It also includes elastic rods 25 ; a plurality of three elastic rods 25 are fixedly connected to each arc-shaped baffle 22 ; each elastic rod 25 is located inside the arc-shaped flexible plate 23 .

[0035] When in use, clean the cable sheath to be tested in advance, then flip one of the arc plates 2 upwards, and place the two moving wheels 4 on the lower arc plate 2 under the cable, as shown in FIG. Figure 3 As shown, the upper arc plate 2 is then folded downward and combined with the lower arc plate 2 to enclose the cable. At this time, the moving wheels 4 on the two arc plates 2 are in contact with the cable, so that the device is put on the cable; the corresponding spring telescopic plate 3 is compressed, allowing the moving wheel 4 to fit tightly against cables of various diameters, which is widely applicable; then the two arc plates 2 are locked together using the latch 10, as shown. Figure 1 and Figure 2As shown, the holding frame 1 is manually held and slowly moved along the cable. During the movement, the wireless camera 5 continuously collects the cable sheath image, and the wireless camera 5 transmits the image data to the external control center, which analyzes and determines the degree of damage to the sheath (such as whether there are defects such as cracks) as a basis for subsequent maintenance and inspection; after the two arc plates 1 2 are put together, the corresponding arc-shaped electric slide rails 6 are also put together to form a ring slide rail. When the control center determines that there is a dispute about the level of damage at a certain point, the position of the equipment is manually adjusted to make the wireless camera 5 aim at the target area, and then the control center The two arc-shaped electric sliders 7 are controlled to slide on the annular slide rail composed of the two arc-shaped electric slide rails 6, so that the damaged area is located between the two arc-shaped electric sliders 7. Then the two electric push rods 8 are controlled to drive the corresponding extrusion plates 9 to move toward the cable. The extrusion plates 9 squeeze both sides of the damaged area of ​​the cable to make potential fine cracks appear or slightly expand, so as to facilitate clearer observation and confirmation of the degree of damage by the wireless camera 5; a pressure sensor is provided between the telescopic end of each electric push rod 8 and the extrusion plate 9, and the extrusion force is monitored and controlled by the pressure sensor to prevent damage to the cable due to excessive extrusion.

[0036] In order to make the center of gravity of the entire equipment located at the center line of the cable, thereby facilitating the movement of the equipment, an arc plate 2 21 is provided on the side of the arc plate 1 2 away from the arc electric slide rail 6, and the arc plate 2 21 balances the weight of the arc electric slide rail 6 and its connected components.

[0037] During the inspection of outdoor cables, the extrusion plate 9 squeezes both sides of the damaged area of ​​the cable, causing potential fine cracks to appear or slightly expand. Outdoor dust can easily enter the cracks, which will subsequently aggravate the wear of the sheath. Therefore, an arc-shaped baffle 22 is welded on each arc-shaped plate 21 and each arc-shaped electric slide rail 6. After the arc-shaped plates 1 2 are put together, the two arc-shaped plates 1 2, the two arc-shaped electric slide rails 6 and the two arc-shaped plates 21 together form a cylinder, and the arc-shaped baffle 22 blocks the opening of the cylinder. Figure 1 As shown, the detection area is enclosed to prevent outdoor dust from entering the cracks; in addition, an arc-shaped flexible plate 23 is provided on the arc-shaped baffle 22, and the arc-shaped flexible plate 23 is in contact with the cable. When the equipment moves to the bend of the cable, the cable can force the arc-shaped flexible plate 23 to deform, and the equipment can move smoothly at the bend of the cable to perform detection operations.

[0038] In a cold environment, the cable sheath becomes brittle, making it inconvenient for the extrusion plate 9 to extrude the damaged area of ​​the cable, and forced extrusion can easily cause damage to the cable sheath; therefore, an electrically controlled heating plate 24 is provided on the arc-shaped baffle 22 to control the electrically controlled heating plate 24 to generate heat to heat the air in the cylinder, thereby heating the area to be detected of the cable sheath, so that the cable sheath softens, thereby facilitating extrusion detection by the extrusion plate 9; it is explained here that a temperature sensor is provided in the electrically controlled heating plate 24 to control the heating temperature so that the heating temperature is always lower than the melting temperature of the sheath, thereby avoiding melting and failure of the sheath, and all electric components in the equipment are high-temperature resistant.

[0039] When the two extrusion plates 9 extrudes the cable, the two extrusion plates 9 are in a V shape. Figure 8 As shown, since one end of the extrusion point is supported by the arc-shaped flexible plate 23, the supporting force is small. When the two extrusion plates 9 squeeze the cable, the cable may move and squeeze the arc-shaped flexible plate 23, resulting in extrusion failure, that is, the microcracks cannot be revealed; therefore, an elastic rod 25 is provided in the arc-shaped flexible plate 23, and the elastic rod 25 maintains rigidity in the longitudinal direction. When the two extrusion plates 9 squeeze the cable, the elastic rod 25 supports the cable to prevent the cable from moving and ensure the extrusion effect; it is explained here that the elastic rod 25 maintains flexibility in the transverse direction and can be forced to deform by the cable, that is, it does not affect the device passing through the cable bend.

[0040] It is explained here that each electronic control component in the device is powered by the storage battery on the grip frame 1.

[0041] Example 2: Based on Example 1, Figures 1-8 As shown, it also includes an insertion rod 31; a drainage port is respectively provided on the arc-shaped plate 2, the arc-shaped electric slide rail 6 and the arc-shaped plate 2 21 below; and an insertion rod 31 is inserted into each drainage port.

[0042] In order to facilitate manual insertion and removal of the insertion rod 31, a protective cover is provided on the insertion rod 31.

[0043] It also includes an L-shaped plate 32 and a second insertion rod 33; each extrusion plate 9 is respectively provided with a plurality of grooves 901; each extrusion plate 9 is respectively plugged with an L-shaped plate 32; each L-shaped plate 32 is respectively welded with a plurality of second insertion rods 33; each second insertion rod 33 is respectively located in a groove 901.

[0044] The present invention can also be used to de-ice cables: when in use, first pull out the plug rod 31 from the lower arc plate 2, the arc-shaped electric slide rail 6 and the arc plate 21 to expose the drainage holes, then pull out the L-shaped plate 32 and the plug rod 2 33 from the extrusion plate 9 to expose the groove 901. At this time, the side of the extrusion plate 9 facing the cable sheath presents an uneven shape, which significantly increases the friction with the ice layer and is conducive to scraping the ice layer; then, put the device on the cable, and then move the device to the iced area to control the ice layer. The electric heating plate 24 is controlled to generate heat to heat the air in the cylinder, thereby heating the ice layer on the surface of the cable sheath, heating the ice layer on the surface of the cable sheath to soften it, and facilitating subsequent scraping. Then the electric push rod 8 is controlled to drive the extrusion plate 9 to move toward the cable, so that the extrusion plate 9 contacts the ice on the cable, and the arc-shaped electric slider 7, the electric push rod 8 and the extrusion plate 9 are controlled to rotate on the annular slide rail composed of two arc-shaped electric slide rails 6. The extrusion plate 9 rotates around the ice layer, and the extrusion plate 9 scrapes the ice layer off. The ice chips melt into water and flow out from the drain port, and the device is controlled to move back and forth on the cable, so that the extrusion plate 9 scrapes off the heated ice layer; it is explained here that the elongation of the extrusion plate 9 is controlled by the wireless camera 5, so that the extrusion plate 9 is always in contact with the ice layer, ensuring the scraping effect, and avoiding the extrusion plate 9 from contacting the cable and wearing the cable; it is explained here that when the cable is squeezed, the second insertion rod 33 is filled in the groove 901, so that the contact surface between the extrusion plate 9 and the cable remains flat, avoiding the cable from sinking into the groove 901 when the cable is squeezed, resulting in the microcracks between the two extrusion plates 9 cannot be shown and expanded; in addition, the arc-shaped flexible plate 23 is set to a sponge material. After the ice layer is scraped off, when the device moves on the cable, the arc-shaped flexible plate 23 of sponge material can absorb the moisture remaining on the cable to prevent the residual moisture from freezing again; compared with traditional deicing equipment (pure mechanical scraping), this solution can significantly reduce scraping resistance, greatly improve deicing efficiency, reduce energy consumption, and reduce the risk of mechanical impact on the sheath.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
