Description

Technical Field

[0001] This application relates to the field of wire detection equipment, and in particular to a detection device for damaged outer skin of transmission wires. Background Art

[0002] Transmission wires usually include an insulating outer skin and a conductive wire core. The insulating outer skin is coated on the conductive wire core so that the conductive wire core is not prone to leakage. Generally, before transporting the transmission wire to the operation site, the operator will use a detection device to perform an integrity detection on the insulating outer skin of the transmission wire.

[0003] In the existing related technology, the above detection device can be seen in the utility model patent with the publication number CN 218496815 U and the publication date of February 17, 2023. This utility model patent discloses a detection device for damaged outer skin of electric wires. It passes a transmission wire through the conductive liquid in an electro-hydraulic barrel through a wire pay-off wheel and a wire take-up wheel, and forms a circuit with an indicator light, a battery, a conductive wire core and the conductive liquid. Then, when the insulating outer skin is damaged and the conductive wire core contacts the conductive liquid, a circuit is formed, so that the indicator light lights up when the insulating outer skin is damaged. This application can realize the detection of slightly damaged insulating outer skin, and the recognition effect is good.

[0004] Regarding the above related technology, the detection device is relatively large in size, which is not convenient for the operator to perform a secondary inspection on the integrity of the insulating outer skin at the operation site. The operator still needs to check by visual inspection or touch, which is relatively inconvenient to use. Utility Model Content

[0005] In order to facilitate the operator to detect the outer skin of the transmission wire at the operation site, this application provides a detection device for damaged outer skin of transmission wires.

[0006] The detection device for damaged outer skin of transmission wires provided by this application adopts the following technical solution:

[0007] A detection device for damaged outer skin of transmission wires includes a liquid storage plate and an indicating component. The liquid storage plate has elasticity and water absorption, and a conductive grid is arranged in the liquid storage plate;

[0008] The indicating component includes a battery, an indicator light and a conductive electrode piece, and the battery, the indicator light, the conductive electrode piece and the conductive grid are electrically connected.

[0009] By adopting the above technical solution, after connecting the conductive wire core at one end of the transmission wire to the conductive electrode piece and storing conductive liquid in the liquid storage plate, the liquid storage plate is covered on the transmission wire, and then the liquid storage plate is moved along the length direction of the transmission wire.

[0010] After the liquid storage plate reaches the damaged part of the insulating outer skin, the conductive liquid seeps into the insulating outer skin and contacts the conductive wire core. As a result, the battery, the indicator light, the conductive electrode piece, and the conductive grid form a circuit with the conductive wire core through the conductive liquid, and the indicator light lights up, thus facilitating the operator to detect the outer skin of the transmission wire at the operation site.

[0011] Optionally, it further includes a hook-and-loop fastener and a fuzzy fastener, and the hook-and-loop fastener and the fuzzy fastener are respectively connected to both ends of the liquid storage plate.

[0012] By adopting the above technical solution, after the liquid storage plate is covered on the transmission wire, by bonding the hook-and-loop fastener to the fuzzy fastener, it is beneficial for the liquid storage plate to be stably covered on the transmission wire.

[0013] Optionally, the liquid storage plate is provided with holes, and the inner wall of the holes is provided with a conductive layer.

[0014] By adopting the above technical solution, the conductive layer is beneficial to ensure that the battery, the indicator light, the conductive electrode piece, and the conductive grid stably form a circuit with the conductive wire core through the conductive liquid, thereby reducing the occurrence of missed detection.

[0015] Optionally, the material of the liquid storage plate is sponge.

[0016] By adopting the above technical solution, the sponge has good elasticity and water absorption, and low cost, which is convenient for production.

[0017] Optionally, it further includes a waterproof insulating substrate, and the liquid storage plate, the battery, the indicator light, and the conductive electrode piece are all arranged on the waterproof insulating substrate.

[0018] By adopting the above technical solution, the waterproof insulating substrate makes it difficult for the operator to be electrocuted by the current when the battery, the indicator light, the conductive electrode piece, and the conductive grid form a circuit with the conductive wire core through the conductive liquid.

[0019] Optionally, the indicating component further includes a buzzer, and the buzzer is electrically connected to the battery.

[0020] By adopting the above technical solution, when the battery, the indicator light, the conductive electrode piece, the buzzer, and the conductive grid form a circuit with the conductive wire core through the conductive liquid, the buzzer sounds, thus facilitating the operator to detect the outer skin of the transmission wire at the operation site.

[0021] Optionally, the indicating component further includes an indicating housing, and the battery, the indicator light, the conductive electrode piece, and the buzzer are all located inside the housing.

[0022] By adopting the above technical solution, the housing makes it difficult for the battery, the indicator light, the conductive electrode piece, and the buzzer to be damaged due to collision during use.

[0023] Optionally, the housing is provided with a buzzer hole which is disposed close to the buzzer.

[0024] By adopting the above technical solution, the buzzer hole facilitates the sound of the buzzer to be transmitted, thereby ensuring the reminder effect of the buzzer on the operator.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. After connecting the conductive wire core at one end of the transmission wire to the conductive electrode plate and storing the conductive liquid in the liquid storage plate, the liquid storage plate is covered on the transmission wire, and then the liquid storage plate is moved along the length direction of the transmission wire;

[0027] When the liquid storage plate reaches the damaged part of the insulating outer skin, the conductive liquid penetrates into the insulating outer skin and contacts the conductive wire core. Furthermore, the battery, the indicator light, the conductive electrode plate, and the conductive grid form a circuit with the conductive wire core through the conductive liquid, and the indicator light lights up, thereby facilitating the operator to detect the outer skin of the transmission wire at the work site;

[0028] 2. After covering the liquid storage plate on the transmission wire, by bonding the hook surface magic tape to the loop surface magic tape, it is beneficial for the liquid storage plate to be stably covered on the transmission wire;

[0029] 3. The waterproof insulating substrate prevents the operator from being electrocuted when the battery, the indicator light, the conductive electrode plate, and the conductive grid form a circuit with the conductive wire core through the conductive liquid. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0036] An embodiment of the present application discloses a device for detecting damage to the outer skin of a transmission wire. Refer to Figure 1 and Figure 2 , the device for detecting damage to the outer skin of a transmission wire includes a waterproof insulating substrate 1, a liquid storage plate 2, a hook surface magic tape 3, a loop surface magic tape 4, and an indicating component 5. In the embodiment of the present application, the material of the waterproof insulating substrate 1 is selected as dense rubber.

[0037] Refer to Figure 1 and Figure 2 , the liquid storage plate 2 is fixedly installed on one side of the waterproof insulating substrate 1, and the liquid storage plate 2 has elasticity and water absorption, and the liquid storage plate 2 is provided with holes (not shown in the figure). In the present embodiment, the material of the liquid storage plate 2 is sponge. The inner wall of the holes of the liquid storage plate 2 is covered with a conductive layer (not shown in the figure) to ensure that the liquid storage plate 2 has good conductivity. Specifically, in the embodiment of the present application, the formation method of the conductive layer is: immersing the liquid storage plate 2 in a conductive solution and then taking it out, and the conductive solution solidifies on the inner wall of the holes of the liquid storage plate 2 to form a conductive layer.

[0038] Refer to Figure 1 and Figure 2 , the hook surface magic tape 3 and the loop surface magic tape 4 are both fixedly installed on the waterproof insulating substrate 1, and the hook surface magic tape 3 and the loop surface magic tape 4 are respectively located at both ends of the liquid storage plate 2. In addition, the hook surface magic tape 3 is arranged close to the liquid storage plate 2, while the loop surface magic tape 4 is arranged far from the liquid storage plate 2, so that after the liquid storage plate 2 is covered on the transmission wire, by bonding the hook surface magic tape 3 to the loop surface magic tape 4, the liquid storage plate 2 can be stably covered on the transmission wire.

[0039] Refer to Figure 2 and Figure 3 , the indicating component 5 includes a housing 51, a battery 52, an indicator light 53, a buzzer 54, and a conductive electrode plate 55. The housing 51 is fixedly installed on the waterproof insulating substrate 1, and the housing 51 is arranged far from the liquid storage plate 2. The battery 52, the indicator light 53, the buzzer 54, and the conductive electrode plate 55 are all fixedly installed in the housing 51, so that the battery 52, the indicator light 53, the buzzer 54, and the conductive electrode plate 55 are not easily damaged due to collision. In addition, the housing 51 is provided with a buzzer hole 511 penetrating through it, and the buzzer hole 511 is arranged close to the buzzer 54, so that the sound of the buzzer 54 can be transmitted out from the buzzer hole 511.

[0040] Refer to Figure 3 and Figure 4, a conductive net 21 is fixedly padded inside the liquid storage plate 2. The conductive net 21 is elastic, and in the embodiment of the present application, the material of the conductive net 21 is copper wire. The conductive net 21, the indicator light 53, the buzzer 54, the battery 52, and the conductive electrode plate 55 are electrically connected in sequence, so that when the conductive net 21 is connected to the conductive electrode plate 55, the indicator light 53 lights up and the buzzer 54 sounds. In addition, a protection resistor R is also connected between the battery 52 and the conductive electrode plate to protect the power supply 52.

[0041] The implementation principle of a transmission wire outer skin damage detection device in the embodiment of the present application is as follows:

[0042] S1. Connect the conductive wire core at one end of the transmission wire to the conductive electrode plate 55, and then add the conductive liquid into the liquid storage plate 2, so that the conductive liquid is temporarily stored in the liquid storage plate 2;

[0043] S2. Cover the liquid storage plate 2 on the transmission wire, and bond the hook surface magic tape 3 to the loop surface magic tape 4, so that the liquid storage plate 2 is tightly fitted against the insulating outer skin of the transmission wire, so that the conductive liquid temporarily stored in the liquid storage plate 2 seeps out;

[0044] S3. Push the liquid storage plate 2 to move along the length direction of the transmission wire through the waterproof insulating substrate 1;

[0045] When the liquid storage plate 2 is at the intact part of the insulating outer skin, the insulating outer skin cuts off between the conductive electrode plate 55 and the conductive net 21, the indicator light 53 goes out and the buzzer 54 is silent.

[0046] When the liquid storage plate 2 reaches the damaged part of the insulating outer skin, the conductive liquid penetrates into the insulating outer skin and contacts the conductive wire core. Furthermore, the battery 52, the indicator light 53, the buzzer 54, the conductive electrode plate 55, and the conductive net 21 form a loop through the conductive liquid and the conductive wire core, the indicator light 53 lights up and the buzzer 54 sounds, so that it is convenient for the operator to detect the outer skin of the transmission wire at the operation site.

[0047] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
