Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for cable deviation measuring instruments, and in particular to a high-efficiency heat dissipation device for cable deviation measuring instruments. Background Technology

[0002] In cable structure, the degree of misalignment between the middle metal core conductor and the insulation layer is called cable eccentricity. Cable eccentricity is an important technical indicator of cable quality. If the eccentricity is too large, the thin-walled side of the insulation layer may be burned through, posing a safety hazard.

[0003] A search revealed a cable deviation meter calibration device (authorization announcement number: CN 218646274 U), which "includes a pushing component, a self-centering clamp, and a calibration cylindrical core. The self-centering clamp includes a base, jaws, and a tension ring. Both the base and the tension ring have through holes for the calibration cylindrical core to pass through. At least three jaws are provided, mounted on the base, and each jaw has a toothed groove. The tension ring has a spiral thread that inserts into the toothed groove. The calibration cylindrical core passes through the through holes. The pushing component connects to the calibration cylindrical core. This structure eliminates the need for additional tools to fix the self-centering clamp, reducing operation steps and greatly improving detection efficiency. The self-centering clamp and the cable deviation meter calibration cylindrical core are fitted together using a sliding fit. The self-centering clamp is automatically centered and installed at the detection interface of the cable deviation meter by rotating the tension ring. The calibration cylindrical core is automatically pushed to the detection position by a cylinder, ensuring detection accuracy."

[0004] Based on the aforementioned related technologies, the applicant believes that the outer casing of the aforementioned polarization meter lacks a heat dissipation mechanism for the telescopic components, which may cause damage due to excessive temperature after prolonged use. In response to the above problem, we have introduced a high-efficiency cable polarization meter heat dissipation device. Utility Model Content

[0005] This utility model discloses a high-efficiency cable deviation measuring instrument heat dissipation device, which aims to solve the technical problem that the deviation measuring instrument is covered by an outer cover but lacks a heat dissipation mechanism for the telescopic parts, which may be damaged due to excessive temperature after long-term use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency cable deviation meter heat dissipation device includes a protective cover. The protective cover has a heat dissipation mechanism inside. The heat dissipation mechanism includes a first heat dissipation component and a second heat dissipation component. The first heat dissipation component and the second heat dissipation component work together. The first heat dissipation component includes ventilation slots. The ventilation slots are arranged in a circumferential array inside the mounting cover. Heat dissipation fins are fixedly connected in a circumferential array on the outer side of the mounting cover. The heat dissipation fins are fixedly connected to the inner wall of the protective cover.

[0008] In a preferred embodiment, the second heat dissipation component includes a heat dissipation shroud, which is fixedly connected to the bottom of the protective cover. The outer side of the heat dissipation shroud has two ventilation slots arranged in a circular array. A dust cover is fixedly connected to the bottom of the heat dissipation shroud, and a dustproof net is fixedly connected to the bottom of the dustproof cover. Mounting bases are symmetrically fixedly connected to both sides of the top of the dustproof net. A motor is fixedly connected inside the dustproof net, and a cooling fan is fixedly connected to the output end of the motor.

[0009] In a preferred embodiment, an L-shaped mounting plate is fixedly connected to the outer side of the mounting cover in a circumferential array, and the interior of the L-shaped mounting plate is provided with threaded holes for installation.

[0010] In a preferred embodiment, the protective cover is made of high-strength, high-thermal-conductivity aluminum alloy or copper alloy.

[0011] In a preferred embodiment, a first ventilation slot is symmetrically formed inside the heat dissipation fins, and the ventilation slots, the first ventilation slot, and the second ventilation slot are used in combination.

[0012] In a preferred embodiment, the motor is electrically connected to an external controller.

[0013] The high-efficiency cable deviation meter heat dissipation device provided by this utility model has the following advantages:

[0014] Firstly, the heat dissipation mechanism can quickly dissipate heat from the heat dissipation fins, allowing for rapid air circulation and replacement. This results in good heat dissipation, ensuring that the temperature inside the protective cover does not continue to rise, thus guaranteeing the safety of the telescopic components. The structure is simple and highly practical.

[0015] Secondly, the expansion joint is fixed inside the mounting cover by bolts and L-shaped mounting plates.

[0022] Reference Figure 1 - Figure 4 A high-efficiency cable polarization meter heat dissipation device includes a protective cover 1. The protective cover 1 has a heat dissipation mechanism inside, comprising a primary heat dissipation component and a secondary heat dissipation component. The primary and secondary heat dissipation components work together. The primary heat dissipation component includes ventilation slots 3 arranged in a circular array inside the mounting cover 2. Heat dissipation fins 4 are fixedly connected in a circular array to the outer side of the mounting cover 2, and the heat dissipation fins 4 are fixedly connected to the inner wall of the protective cover 1. The secondary heat dissipation component includes a heat dissipation cover 6 fixedly connected to the bottom of the protective cover 1. Secondary ventilation slots 7 are arranged in a circular array on the outer side of the heat dissipation cover 6.

A motor 11 is fixedly connected inside the dustproof net 9, and a cooling fan 12 is fixedly connected to the output end of the motor 11.

[0023] In the above technical solution, considering that the outer casing of the polarization meter lacks a heat dissipation mechanism for the telescopic components, it may be damaged due to excessive temperature after prolonged use. To solve this problem, the specific operation is as follows:

[0024] Reference Figure 1 - Figure 4In a preferred embodiment, during actual use, the telescopic component is placed inside the mounting cover 2. During the use of the telescopic component, a large amount of heat is generated. The heat is dissipated through the mounting cover 2 to the heat dissipation fins 4. The heat dissipation fins 4 absorb and dissipate the heat. Then, the operator starts the motor 11. The output end of the motor 11 drives the cooling fan 12 to rotate. The cooling fan 12 rotates and begins to dissipate heat from the inside of the protective cover 1. Through the set heat dissipation mechanism, the heat on the heat dissipation fins 4 can be quickly discharged, and the air can be quickly circulated and replaced. The heat dissipation effect is good, ensuring that the temperature inside the protective cover 1 will not continue to rise, ensuring the safety of the telescopic component. The structure is simple and the practicality is strong.

[0025] Reference Figure 1 - Figure 4 In a preferred embodiment, L-shaped mounting plates 13 are fixedly connected in a circumferential array on the outer side of the mounting cover 2. The L-shaped mounting plates 13 have threaded holes for installation inside. The protective cover 1 is made of high-strength, high-thermal-conductivity aluminum alloy or copper alloy. A first ventilation slot 5 is symmetrically formed inside the heat dissipation fins 4. Ventilation slots 3, 5, and 7 work together. The motor 11 is electrically connected to an external controller. The telescopic component is fixed inside the mounting cover 2 by bolts and the L-shaped mounting plates 13. The first ventilation slot 5, 3, 5, and 7 increase airflow speed and improve heat dissipation efficiency. The controller allows for convenient operation of the motor 11, making operation simpler.

[0026] Working principle: In actual use, the telescopic component is placed inside the mounting cover 2, and then fixed inside the mounting cover 2 by bolts and L-shaped mounting plate 13. Then the telescopic component is put into use. During the use of the telescopic component, a large amount of heat is generated. The heat is dissipated to the heat dissipation fins 4 through the mounting cover 2. The heat dissipation fins 4 absorb and dissipate the heat. Then the operator starts the motor 11. The output end of the motor 11 drives the cooling fan 12 to rotate. The cooling fan 12 rotates to dissipate heat inside the protective cover 1, quickly expelling the heat on the heat dissipation fins 4 and achieving rapid air circulation and replacement.
