Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to an adjustable cable fault tester with heat dissipation components. Background Technology

[0002] The adjustable cable fault tester integrates multiple detection technologies such as low-voltage pulse method and high-voltage flashover method, which can quickly and accurately test various cable faults, including flashover and high resistance faults, and can be tested directly without burning through. In addition, the tester also has waveform and parameter storage and retrieval functions, dual-trace display function, and waveform expansion ratio function, which facilitates users to further analyze and judge the fault.

[0003] However, existing cable fault testers often struggle to dissipate internal heat effectively during prolonged operation, leading to overheating and impacting their performance and lifespan. While some testers incorporate heat dissipation structures, these often suffer from low efficiency and inadequate dust protection. When the instrument is idle, it cannot effectively prevent dust intrusion, which accumulates over time. This accumulated dust inevitably interferes with the instrument's normal operation, ultimately affecting its accuracy and reliability in cable fault detection. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable cable fault tester with a heat dissipation component that combines dust protection and heat dissipation to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An adjustable cable fault tester with heat dissipation components includes a tri-proof box and a control panel installed in the tri-proof box, with installation ports on both sides of the tri-proof box;

[0007] It also includes:

[0008] Cooling fans are installed on both sides of the inner surface of the tri-proof box;

[0009] A heat sink, wherein the heat sink is disposed on the mounting port;

[0010] A shielding leaf is rotatably mounted on the heat sink to shield the heat sink.

[0011] An electromagnet is mounted on a heat sink and connected in series with a cooling fan. The electromagnet causes the shielding blades to deflect.

[0012] As a further optimization of this utility model, the heat sink plate is provided with multiple heat dissipation holes, which are arranged in a ring array. Each heat dissipation hole is provided with a dust cover, and a limiting ridge is provided on one side of each heat dissipation hole.

[0013] As a further optimization of this utility model, a crossbar is provided on the heat dissipation plate, the shielding leaf is rotatably mounted on the crossbar, a torsion spring is sleeved on the crossbar, the two ends of the torsion spring are respectively connected to the shielding leaf and the heat dissipation plate, and a magnetic sheet is provided on the shielding leaf.

[0014] As a further optimization of this utility model, the electromagnet is provided with an extension plate, which is located on the limiting ridge, and the electromagnet can attract the magnetic sheet.

[0015] As a further optimization of this utility model, multiple mounting pads are provided between the cooling fan and the tri-proof box.

[0016] As a further optimization of this utility model, the two cooling fans rotate in the same direction.

[0017] The beneficial effects of this utility model are as follows:

[0018] Unlike existing technologies, in actual use, the rotating shielding blades on the heat sink can shield the heat sink when it is not dissipating heat, further preventing dust. When the tester is working, the cooling fan is connected in series with the electromagnet. When the electromagnet is energized, it generates magnetism, attracting the magnetic sheet on the shielding blade. This causes the shielding blade to deflect against the elastic force of the torsion spring, thereby opening the heat sink for heat dissipation. This achieves automatic switching between heat dissipation and dust prevention. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 - Figure 4 As shown, the adjustable cable fault tester with heat dissipation components includes a tri-proof box 1 and a control panel 2 installed in the tri-proof box 1. The tri-proof box 1 has installation ports 3 on both sides.

[0027] It also includes:

[0028] Cooling fan 4 is installed on both sides of the inner surface of the tri-proof box 1;

[0029] Heat sink 5 is mounted on mounting port 3;

[0030] The shielding leaf 6 is rotatably mounted on the heat sink 5 to shield the heat sink 5.

[0031] Electromagnet 7 is mounted on heat sink 5 and connected in series with cooling fan 4. Electromagnet 7 causes the shielding blades 6 to deflect.

[0032] The heat sink 5 has multiple heat dissipation vents 51 arranged in a ring array. Each heat dissipation vent 51 is equipped with a dust cover 52, which can effectively prevent dust from entering the instrument and ensure the normal operation environment of the instrument. A limiting ridge 53 is provided on one side of the heat dissipation vent 51, which restricts the initial position of the blocking leaf 6.

[0033] A crossbar 61 is provided on the heat sink 5, and a shielding leaf 6 is rotatably mounted on the crossbar 61. A torsion spring 63 is sleeved on the crossbar 61. When the electromagnet 7 is not energized, the shielding leaf 6 keeps shielding the heat sink 5, thus preventing dust. When the electromagnet 7 is energized, the shielding leaf 6 deflects against the elastic force of the torsion spring 63, thereby achieving heat dissipation. The two ends of the torsion spring 63 are connected to the shielding leaf 6 and the heat sink 5, respectively. A magnetic sheet 62 is provided on the shielding leaf 6.

[0034] An extension plate 71 is provided on the electromagnet 7, which is located on the limiting ridge 53. The electromagnet 7 can attract the magnetic sheet 62. The electromagnet 7 is connected in series with the cooling fan 4. When energized, it generates magnetism and attracts the magnetic sheet 62 on the blocking leaf 6, causing the blocking leaf 6 to deflect. The extension plate 71 reduces the distance between the electromagnet 7 and the magnetic sheet 62, ensuring the relative position of the electromagnet 7 and the magnetic sheet 62, and ensuring that the electromagnet 7 can effectively attract the magnetic sheet 62.

[0035] Multiple mounting pads 41 are installed between the cooling fan 4 and the tri-proof box 1 to buffer and reduce vibration, thereby reducing the impact of vibration generated by the cooling fan 4 during operation on the instrument and improving the reliability of the instrument.

[0036] The two cooling fans 4 rotate in the same direction, which can better promote air circulation in the tri-proof box 1, accelerate heat dissipation, effectively prevent the instrument from degrading due to overheating, and improve the stability and service life of the instrument.

[0037] It should be noted that the working principle of the adjustable cable fault tester with heat dissipation components is as follows: The tester includes a tri-proof box 1 and a control panel 2 inside it. The tri-proof box 1 has mounting ports 3 on both sides. When the tester is working, the cooling fan 4 starts. The cooling fan 4 is located on both sides of the inner surface of the tri-proof box 1 and is connected in series with the electromagnet 7. At this time, the electromagnet 7 is energized and generates magnetism. The energized electromagnet 7 can attract the magnetic plate 62, so that the shielding leaf 6 overcomes the elastic force of the torsion spring 63 and deflects, thereby opening the heat dissipation plate 5 to facilitate air circulation and heat dissipation through the heat dissipation port 51. Multiple mounting pads 41 are set between the cooling fan 4 and the tri-proof box 1 to play a role in buffering and shock absorption. In addition, the two cooling fans 4 rotate in the same direction, which helps to better promote air circulation in the tri-proof box 1 and achieve better heat dissipation effect.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
