Description

Technical Field

[0001] The utility model relates to the field of production technology of electric wires and cables, in particular to an automatic drying device used for a high-frequency spark tester. Background Art

[0002] The high-frequency spark tester is an online detection device placed on the wire and cable take-up part during the production of wires and cables. Its main function is to load a periodic voltage of a certain frequency onto the wire and cable to be tested to detect whether the wire and cable have copper leakage, broken skin, surface impurities, or unqualified insulation withstand voltage. Since the wires and cables need to be cooled in a water tank, there will be water on the surface. Excessive water will accumulate on the detection bead chain of the high-frequency spark tester, which will cause the spark tester to falsely alarm and cause the equipment to automatically shut down, resulting in economic losses. The need for manual drying and dehumidification of the detection bead chain on a regular basis will result in labor cost losses. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a device with a simple structure and convenient operation, which can avoid the economic losses of scrapped wires and repeated inspections caused by automatic shutdown of the equipment due to false alarms, as well as the labor cost losses caused by manual drying and dehumidification of the detection bead chain.

[0004] The utility model is implemented as follows: an automatic drying device for a high-frequency spark tester, comprising:

[0005] A bead chain cover, the bottom wall of which is a double-layer structure with a cavity, the upper layer of which is provided with a plurality of through holes, the middle of the lower layer of which is provided with an air inlet, and a plurality of detection bead chains are installed in the bead chain cover;

[0006] a hot air blower connected to the air inlet of the bead chain cover through an air duct;

[0007] a humidity sensor, disposed on a side wall of the bead chain cover;

[0008] A control device is communicatively connected to the humidity sensor and the hot air blower.

[0009] Furthermore, the bottom wall of the bead chain cover is an arc-shaped structure.

[0010] The advantage of the utility model is that by setting the bottom wall of the bead chain cover into a double-layer hollow structure and connecting a hot air blower and a humidity sensor, the humidity in the bead chain cover can be automatically detected, and the hot air drying function can be automatically started according to the humidity detection. By adding an automatic drying device, the utility model can avoid false alarms of the equipment, causing the equipment to automatically shut down, resulting in economic losses such as scrapping of wires and repeated inspections, as well as labor cost losses caused by manual drying and dehumidification of the detection bead chain.

[0014] Description of the accompanying figures: bead chain cover 1, bottom wall 11, through hole 111, air inlet 112, cavity 12, side wall 13, hot air blower 2, air duct 21, humidity sensor 3, control device 4, detection bead chain 100. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 and Figure 2 As shown, the utility model is an automatic drying device for a high-frequency spark tester, comprising: a bead chain cover 1, a hot air blower 2, a humidity sensor 3 and a control device 4.

[0017] The bottom wall 11 of the bead chain cover 1 is a double-layer structure with a cavity 12, and the upper layer is provided with a plurality of through holes 111, and the middle part of the lower layer is provided with an air inlet 112, and a plurality of detection bead chains 100 are installed in the bead chain cover 1; the bottom wall 11 of the bead chain cover 1 is an arc-shaped structure, and the arc-shaped structure allows the height of the wires to be better adjusted when the wires pass through the bead chain cover 1. The hot air blower 2 is connected to the air inlet 121 of the bead chain cover 1 through an air duct 21, and the hot air blower 2 passes the hot air into the cavity 12 of the bottom wall 11 of the bead chain cover through the air duct 21, and then blows the hot air to the detection bead chains 100 through the through holes 111 for drying; the humidity sensor 3 is arranged on the side wall 13 of the bead chain cover 1, and is used to detect the humidity in the bead chain cover 1; the control device 4 is communicatively connected to the humidity sensor 3 and the hot air blower 2, and the control device 4 is used to receive the detection value of the humidity sensor 3 and control the switch of the hot air blower 2.

[0018] Working principle: When the humidity sensor 3 detects that the humidity in the bead chain cover 1 exceeds a certain value and transmits it back to the control device 4, the control device 4 starts the hot air blower 2 to generate hot air and blows and dries the inside of the bead chain cover 1 through the air inlet 112 and the through hole 111. When the humidity sensor 3 detects that the humidity in the bead chain cover 1 drops to a certain value, the control device 4 turns off the hot air blower 2 and stops blowing hot air, and the automatic drying is carried out in this cycle.

[0019] The advantage of the utility model is that by setting the bottom wall 11 of the bead chain cover 1 into a double-layer hollow structure and connecting the hot air blower 2 and the humidity sensor 3, the humidity in the bead chain cover 1 can be automatically detected, and the hot air 2 drying function can be automatically started according to the humidity detection. By adding an automatic drying device, the utility model can avoid false alarms of the equipment, causing the equipment to automatically shut down, resulting in economic losses such as scrapping of wires and repeated inspections, as well as labor cost losses caused by manual drying and dehumidification of the detection bead chain.

[0020] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
