Abstract
The invention discloses an automatic drainage system for a cable trench of a transformer substation. The automatic drainage system comprises a cable trench structure, a cover board structure and a control mechanism, wherein the cover board structure is arranged on the upper part of the cable trench structure, the control mechanism is connected with the cable trench structure, the cable trench structure comprises an upper tunnel and a lower tunnel, a partitioning board is arranged between the upper tunnel and the lower tunnel, and a cable holder is arranged in the cable holder. According to the automatic drainage system, the double-layer tunnel structure is adopted, so that humus and water can be separated; the inclined partitioning board is adopted, so that water can flow into the lower tunnel as much as possible, and the contact between the humus and water is avoided; a single-chip microcomputer controller is adopted for controlling, so that the functions of draining water and absorbing moisture for the cable trench are automatically realized; meanwhile, a water-proof belt and a bulged cover board are arranged on the upper tunnel, so that the water inlet amount can be reduced, the water inlet amount of the cable trench is reduced by 50% or above, the service life of a cable is prolonged by 30% or above, and thus the automatic drainage system is worthy of being popularized and applied.
Description
Technical field
The invention belongs to cable duct technical field of drainage, be specifically related to a kind of cable duct of substation automatic drain system。
Background technology
In the last few years, continuous expansion along with city size, the capital construction in city continues to increase input, all trades and professions all present the flourish impetus, power consumption is ever-increasing while, the stability of power supply needs further stable, and in the important step as supply, cable in cable duct of substation is often due to be in underground, it is chronically in the environment of humid and wire is easily corroded, thus causing that circuit corrosion causes the generation of power-off, and existing technology adopts artificial drainage more, or open cable channel cover plate and carry out the mode of dry in the sun, not only waste time and energy but also poor effect, a kind of automatic drainage system for cable tunnel disclosed in CN101725369A, belong to draining field；It includes cable tunnel, sump, main drainage pipeline, immersible pump A, immersible pump B, and high water level is popped one's head in, and low water level is popped one's head in, zero level probe etc.；When low water level, start immersible pump A draining, when high water level, start immersible pump B draining simultaneously；But cable can not be separated by it with wet environment, cable is made to be in wet environment, and can not be dried and prevent moisture from entering, this immersion making to cannot be avoided sewage, and owing to water making to fill the air various gas and humus liquid in cable duct containing humus, accelerate the damage to cable on the contrary, it is therefore desirable to a kind of solid-liquid separation can either be can guarantee that again cable duct air drying and prevent the drainage system into water。
Summary of the invention
The technical problem to be solved is can not to carry out solid-liquid separation for existing cable ditch and there was dampness in the air, and impeded drainage makes the phenomenon that cable is immersed in humus liquid, and provides a kind of safe and simple cable duct drainage system。
Problem by solving the present invention be the technical scheme is that a kind of cable duct of substation automatic drain system, including cable duct structure, covering plate structure and controlling organization, described cable duct structure upper arranges covering plate structure, described controlling organization is connected with cable duct structure, described cable duct structure includes tunnel and lower tunnel, between described upper tunnel and lower tunnel, division board is set, described upper tunnel arranges cable bearer, described upper tunnel sidewall arranges ventilating fan and drimeter, in described lower tunnel, water-level gauge and suction pump are set, described water-level gauge is connected with controlling organization with suction pump, described controlling organization is singlechip controller。
Described covering plate structure is protruding cover plate, and described protruding cover plate bottom arranges V-groove, and top, described upper tunnel arranges triangle track。
Described ventilating fan are connected with controlling organization with drimeter。
Described division board is the notch plate that centre arranges flowing water seam。
The present invention adopts the design of double-deck tunnel and is arranging flowing water seam in-between, make moisture can pass through gap and flow into lower tunnel, also so that it can play the effect of filter plate, and can only can not say that humus flows into bottom by drainage owing to gap is less, thus humus is separated with moisture, so that it can prevent humus from fermenting in water, produce corrosive liquid and gas, accelerated corrosion；Two side, upper tunnel arranges cable bearer so that cable can be disposed thereon by it, form the cable floor of stratiform so that cable is arranged and unsettled wherein in order, and arranges humidity sensor at sidewall so that it can detect the humidity change in tunnel；Lower tunnel arranges water-level gauge and water pump so that it is able to detect that the change of water level, and feeds back information to controlling organization so that it can control the folding of suction pump so that water can will be taken away by it when water level is too high, thus keeping the dry of cable duct；At the humidity sensor that upper tunnel sidewall is arranged so that the information of monitoring can be passed to controlling organization by it so that controlling organization is controlled according to the threshold value set, thus realizing the folding of ventilating fan, is aerated；Arranging triangle slideway on top, upper tunnel so that it can play the effect of isolation water, protruding cover plate makes cover plate it can be avoided that moisture on the cover board stockpiles simultaneously, thus decreasing the water accumulating volume entered in tunnel；Reduce inflow thus reducing soak time and the water yield of pump-out and humus。
The present invention adopts double-deck tunnel, so that it can humus is separated with water, and adopt the division board of inclination, make the moisture can under inflow as much as possible in tunnel, avoid humus and contact with moisture, adopt singlechip controller can control so that it can be automatically obtained the draining removal function to cable duct, adopt simultaneously and the water blocking tape mode with projection cover plate is set in upper tunnel so that it can reduce and enter the water yield, make cable duct decreased influent flow more than 50%, extend cable service life more than 30% simultaneously, be worthy to be popularized and application。
