Waterproof cable well

Abstract

The invention discloses a waterproof cable well, which comprises a well body, wherein the low-lying area at the well bottom of the well body is provided with a sump; the top face of the well body is provided with a fan heater; the fan heater comprises a humidity sensor; the sump is internally provided with an ultrasonic atomization device; a mist collecting hood is arranged above the sump; a suction pipe and an exit pipe of the mist collecting hood are communicated; repellent paint is painted on the inner surface of the well body; the components and the weight parts of the repellent paint is as follows: 50-100 parts of polyether, 5-8 parts of epoxy resin, 5-15 parts of polytetrafluoroethylene, 5-15 parts of polyether ether ketone, 0.5-1.5 parts of plasticizer, 10-15 parts of polyurethane, 1-5 parts of simethicone, 5-10 parts of nanometer silicon dioxide and 30-50 parts of ethanol. The waterproof cable well has the advantages that the waterproof cable well is capable of draining water continuously and timely in a rainy humid environment, and the waterproof and dehumidification performances are realized.

Description

technical field [0001] The invention relates to the technical field of cable matching devices, in particular to a waterproof cable well. Background technique [0002] When the cable line is laid, a cable well must be set at a certain distance. The importance of the cable line does not need to be repeated, and the waterproof of the cable well has a great influence on the stability of the cable line. Since the cable well is often set under the ground , the surface temperature inside the well is lower than the ambient temperature. In the case of excessive humidity, it will cause severe condensation water corrosion and seriously affect the power cable; in addition, in a rainy and humid environment, the cable well is continuously intruded by water. , although the amount is not much, the water in the cable well cannot be drained in time and continuously, and the cable well is prone to high humidity. [0003] Existing patent documents, for example, the Chinese patent application w...

Problems solved by technology

[0006] The technical solutions disclosed above all only use structural improvement to strengthen the waterproofing of the cable well, but none of them drain the water in time and continuously, and all of them need to manually drain the water after detecting the accumulated water, which increases labor costs and reduces Therefore, at present, it is difficult to achieve the effect of waterproofing and dehumidification inside the cable shaft at the same time only by improving the structure
