The utility model provides an automatic drainage system of a cable tunnel, which has low cost, and can timely and effectively solve the problem of seeper in a cable trench.
Description
(1) technical field
The utility model relates to a kind of automatic drain system, particularly, relates to a kind of system that is applied to the cable tunnel draining.
(2) background technology
Urban sewerage and drainage system links to each other because it is got along well with the cable tunnel in roadside in the cable tunnel of transformer station, seepage or the water that flows to can't be discharged, and form long-term ponding, and rainwater may be full of sewage season, even if the dry season, generally also there is the dark sewage of 1.5-1.8 rice the inside., the line fault or the inspection of line checks that the existence of sewage can influence workman's construction, therefore, has to the sewage emptying is constructed again because often needing to enter described cable tunnel.Often need quick maintenance for line fault, and the tens of at least sides of sewage in the cable trench, hundreds of side adds the time of calling drainage plant at most, has delayed the repair time greatly, may cause great economic loss thus.In addition, cable may cause puncture, to such an extent as to produce electric leakage in the medium-term and long-term insulating properties that can influence cable of soaking of water; On the other hand, in case cable leakage contains a large amount of electrolyte in the sewage, electric conductivity is very good, may damage formation.In addition, the cable tunnel directly leads to transformer station, and some transformer station's physical features is lower, is easy to cause backing up of sewage, and the operate as normal of transformer station can be subjected to very big influence.
(3) summary of the invention
Therefore, the utility model provides a kind of cost low at the problem that will solve ponding in the cable tunnel at present, can solve the automatic drainage system for cable tunnel of the problem of cable trench water collecting timely and effectively.
In order to realize goal of the invention of the present utility model, the technical solution adopted in the utility model is:
The utility model automatic drainage system for cable tunnel, it comprises:
Drainage plant is arranged in cable shaft or the cable tunnel, is used to extract the ponding in the cable tunnel;
The liquid level deriving means is used to obtain the liquid level data in the above-mentioned cable tunnel; And
Controller is used for according to said liquid level data and sets high liquid level comparing, and sets high liquid level if be higher than, and starts described drainage plant, and compares the real-time level data and set low liquid level, as if being lower than low liquid level, stops described drainage plant.
Above-mentioned automatic drainage system for cable tunnel, it further comprises human-computer interaction device, to be used for manually controlling described drainage plant.
Above-mentioned automatic drainage system for cable tunnel, described controller input terminal comprise that one is used for the input point of manual mode and automatic mode conversion.
Described human-computer interaction device is a touch-screen, also can set said high liquid level and low liquid level by this touch-screen.
Adopt fluid level transmitter for said liquid level deriving means.
Above-mentioned automatic drainage system for cable tunnel, the lifting pipe outlet of described drainage plant is positioned at the sink hole adjacent with described cable shaft.
Above-mentioned automatic drainage system for cable tunnel, it comprises that further one is positioned at the electrical control cabinet on ground, described drainage plant top, described lifting pipe is positioned at below the face of land.
Described cable tunnel is provided with a groove that is lower than its bottom surface, and the water inlet pipe of described drainage plant is positioned at this groove.
Above-mentioned automatic drainage system for cable tunnel, it further comprises the leakage detector of a device on cable, its signal is reported to the police by a warning device that is connected to controller output end after described controller is handled.
Above-mentioned automatic drainage system for cable tunnel, described dewatering installation is provided with the overcurrent no-voltage protection device, and hot overload protection device.
According to the technical solution of the utility model as can be known, owing to adopted special drainage system, make that the cable tunnel seeping phenomenon is solved.So, consider energy consumption, this programme employing liquid level deriving means comes the liquid level in the detection streamer tunnel, when liquid level is higher than the high liquid level of setting, just start drainage system, when liquid level was lower than described high liquid level at ordinary times, drainage system was in holding state, simple liquid level deriving means, no matter be the liquid level sensor of using always, still emerging fluid level transmitter, power consumption all seldom, less energy intensive when just whole system is in the real-time monitor state of high liquid level.But then, if cable breaks down or needs to call under the maintenance situation that pumping equipment draws water is not only the energy consumption aspect temporarily, the situation that also has the social benefit aspect to be subjected to greatly influence is compared, and the social benefit of this programme is better.
In addition, as saying in the background technology, as long as effectively got rid of the ponding in the cable tunnel, will reduce the dangerous and possible personnel's injury of electric leakage of cable, society and economic benefit are ensured.
