Operating principle of the present invention is, the bridge floor spilled water hole of directly flowing through flows in the gutter that lays along the bridge outside, flows into the U-shaped detector tube then; Liquid level raises gradually and floods second sensor in the U-shaped detector tube; After the liquid and second sensor satisfied detection requirement time of contact, second sensor sends the water quality detection signal respectively to controller, after controller is resolved the sensor electrical signal; Water quality criterion identification water quality according to preset in the controller is normal flow or accident leakage thing; And, make water to flow into sedimentation basin or inflow collecting pit according to the electromagnetic valve action changing flow direction on the recognition result control subordinate pipeline, the bridge floor runoff is carried out selective collection by water quality; Bridge floor comes water when detecting to accident leakage, flows into collecting pit; When detecting, get into sedimentation basin to normal flow.Sedimentation basin has retaining and deposition double action concurrently; The bridge floor runoff comes water behind preliminary sedimentation, to flow into the clarifier of subordinate certainly; The combination filtering layer that clarifier is made up of cobble, zeolite and coarse sand has crown_interception preferably to suspension contained in the bridge floor runoff, and the clarifier water outlet enters gutter.
Can know that by said structure controller is encoded the sensor detection signal and afterwards is sent to the watch-dog of Surveillance center through optical fiber or GPRS router synchronization, shows after being resolved by watch-dog, supplies staff's decision references.Controller is except transmitting control signal, parsing, processes sensor detection signal and processing, the transmission camera video signal, also undertaking and be power devices functions such as sensor, and the power supply of controller can be by civil power behind transformer rectifier circuit; Be output as and demand correspondent voltage, electric current; Also can be equipped with power supply, like battery, battery pack etc.; For avoiding influencing the stability of controller operation, equipment that some driving powers are bigger such as electromagnetic valve adopt the independent current source power supply.Watch-dog is an industrial computer, realizes functions such as real-time demonstration, the equipment state of bridge floor equipment running status are consulted, the equipment operational factor is provided with by computer software.Categories of sensors among the present invention has: pH sensor, conductivity sensor, turbidity transducer, combustible gas sensor; The sensor detected object covers acidic liquid, akaline liquid, conducting liquid, volatile inflammable liquid, various salt, has covered the kind that speedway transports common dangerous material basically.Nonetheless, to some classification dangerous material, for example edible oil still can't be realized instant identification, and the camera of bridge floor monitoring usefulness is set for this reason, through video mode identification bridge floor accident, to remedy the deficiency of sensor detectability.The underlying parameter that provides according to electromagnetic valve supplier; Watch-dog possesses the valve core of the electromagnetic valve closure state and detects recognition function; This state transfers to watch-dog and is presented on the screen behind coding, each position electromagnetic valve valve state comes into plain view, and makes things convenient for staff's manual operation.After solenoid-driven refers to that specifically sensor detects the exception water quality signal; Compare with the accident discrimination standard that predefined is good in the watch-dog storage system; Meet accident water quality characteristic conducting driving circuit for electromagnetic valve immediately; Control two-bit triplet electromagnetic valve valve switches to the dump state from normal emissions status, and collecting pit is gone in the logistics of guiding accident leakage.The U-shaped detector tube be one section U-bend, bend pipe inflow direction height is a little more than the direction of anhydrating (press hydraulic slope nature the discrepancy in elevation get final product), the second interior sensor of U-shaped detector tube is installed in the arbitrary vertical pipeline section of U-bend all can; But be installed in leftward position than the right side more help coming water mix (such as Fig. 2 mark), vertically the pipeline section height depends in the sensor combination height of long pass sensor, can be short slightly when not receiving the size sensor restriction; But unsuitable too short, the one, reserve external labeling type ultrasonic flowmeter paster installation site, the 2nd, the flow meter detection needs stable full packages current; Vertical tube is too short; Current are prone to fluctuation, a sensor combination are arranged, i.e. second sensor in the U-shaped detector tube; After adopting sensor combination, electrochromic substance behind monitoring target covering acid, alkali, salt, volatile combustible gases, the molten water.Ageing and the reliability for the raising system; In conjunction with existing sensors classification and speedway dangerous material classification, system is detected the period divide into the two kinds of weather conditions in sleet sky and non-sleet sky, for the bridge floor main frame weather conditions information is provided by the sleet sensor; At non-sleety weather; The electromagnetic valve acquiescence is positioned at the dump state, and detected any flow all is identified as dangerous material and leaks the collecting pit of inflow accident leakage in the U-shaped detector tube; Under the sleety weather situation, judge whether dump,, otherwise flow into sedimentation basin if dump flows into the accident leakage collecting pit according to the sensor combination testing result.After monitoring was optimized the period, all flows on non-rainy day no matter whether detect, all got into the Ji Chi that accident leakage is received, and have significantly improved the accident leakage recall rate.
Clarifier of the present invention is after the initial stage runoff gets into, and carries out water distribution through " rich " font distribution pipe, and distribution pipe is located at the clarifier bottom; End openings is used the pipe plug shutoff, and 5～10cm evenly gets out circular hole in water pipe lateral separation, pipeline section upper edge, is staggered; Do not stop up, do not fall into circular hole and be as the criterion with cobble, when cobble particle diameter difference is big, should take measures to prevent that cobble from stopping up, falling into circular hole; The boring purpose is a uniform water distribution on the distribution pipe, when upland water is flowed through the filter material gap, can subdue certain degree because of its tortuous rotating obstruct and upwelling water outlet and come water potential energy; Help to form the mild upwelling that is evenly distributed, water changes laminar flow into by turbulent flow and is evenly distributed on the filter material layer cross section in the future, makes full use of the filter capacity of filtrate on the one hand; The stable upwelling that forms on the other hand prevents to filter the high concentration of sediment overflow of carrying under one's arms of back flow-shape shakiness, cobble, zeolite, the coarse sand of laying depth 40cm according to this on distribution pipe top; Particle diameter diminishes from down to up step by step; Lay filter between each filter material layer, prevent the mixing of filtrate excessive convergence, reduce the gap rate of lower floor's filtrate.The filter material layer top also has 50cm highly not fill filtrate to the overflow weir top, and this highly is the sediment settlement layer, in order to the sand grain of carrying under one's arms in the further removal water outlet.Because runoff is extremely slow through flow velocity behind the filtration beds, in filter process, stopped and fine particle that runoff is carried under one's arms during through the coarse sand filtration beds, because of going up more greatly behind certain altitude, density settles down gradually.Current are successively through behind cobble, zeolite, the coarse sand filtration beds; Hold back most of particulate pollutant,, be full of the pond body gradually along with coming water to continue; After the fine particle that the sedimentation of filtrate space segment falls to carry was not filled on clarifier top, the outlet pipe that flows into right part pond body through overflow weir entered gutter.And, obtained good effect through the repetition test test, concrete condition is following:
For solving initial stage runoff pollution problem, to the water quality characteristics of bridge floor runoff, introduce clarifier in the present invention, be used for holding back the major pollutants SS (suspended particle in the water) of initial stage runoff, and COD (COD) is also had certain removal effect.With SS, COD, BOD in the initial stage runoff pollution thing of gathering
5Test result plots curve, finds SS, COD, BOD
5Concentration curve be substantially parastate, combine the water quality characteristics deduction of initial stage runoff, the COD in the water sample, BOD
5Concentration quite a few is arranged is by the SS in water sample contribution; It is same water sample; Behind filtering SS, test COD and do not filter SS test COD; The result who obtains is inconsistent, gathers the native simulated experiment result who is done in urban transportation main line roadside and shows that COD and SS concentration correlation reach 87.2%, show that above-mentioned deduction is correct.
The filtrate that clarifier adopted is a cobble, basalt, and quartz sand, the flowing velocity of current in these materials depends on the transmission coefficient of filtrate, the disposal ability of device then depends on transmission coefficient and filtering ponds discharge area.
Transmission coefficient is a composite target of reflection soil or other granular material water permeability, depends primarily on characteristics such as coating of particles, size, uniformity coefficient and space.The transmission coefficient of different medium is different.Transmission coefficient is a physical quantity that dimension is arranged, and dimension is the same with flow velocity.
