Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, in particular to a control cabinet for watertight detection of inclined cables. Background Art

[0002] In order to improve the safety of bridge structures, it is necessary to study the dynamic watertightness of the cable system, which is conducive to evaluating the watertightness performance of the cable system under actual working conditions, identifying and solving possible watertightness problems, and reducing human resource investment in the test process. The control cabinet used for watertight detection of inclined cables is used to carry computer-side software automatic control hardware equipment.

[0003] In the prior art, for example, a PLC control cabinet with patent publication number CN207692279U that can safely dissipate heat has a detachable dust-proof net assembly on the vent to prevent dust from entering while dissipating heat. However, the control cabinet used for the watertightness detection of the inclined cable is connected to a large number of transmission wires, and an additional dust-proof mechanism is required at the wire outlet. For example, an elastic inlet and outlet of an electrical control cabinet with patent number CN203491511U achieves dust-proof effect by filling the outlet with sponge. However, the sponge dust-proofing not only increases the complexity of the operation when arranging the cables, but the frequent movement of the wires during the watertightness detection of the inclined cable will also affect the sealing of the sponge. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a control cabinet for watertight detection of inclined cables, which has the advantages of strong heat dissipation and dust prevention effects while improving the convenience of cable arrangement, and solves the problem of high complexity of cable arrangement operation and poor ventilation effect resulting in low heat dissipation effect when sponge filling is used at the cable outlet in the prior art.
