Description

Expressway greening rainwater water-saving spray device based on PLC
Technical field
The present invention relates to a kind of expressway greening rainer, particularly, belong to the automatic irrigation technical field based on the expressway greening rainwater water-saving spray device of PLC.
Background technology
Highway is far away from place, water source, urban district, manually sprays rainwater, and in the summer of sweltering heat, the greening work personnel labor intensity is big, is not suitable for the work of long-term spray water.Artificial spray water cost is higher, sprays the machinery water spray and adopt, and needs the expenditure cost of labor on the one hand, and the cost that sprays machinery on the other hand is also very high.
Though water resources in china is more, quantity per capita is not abundant, and in the time of arid weather, the lack of water situation often appears in some area.And highway is far from the water source, urban district, the water resource allocation and transportation are inconvenient, therefore need be in the drilling well of highway correct position, replace the urban district water resource with well water, the rainwater utilization facility is set simultaneously, adopt the complementation of rainwater and well water water supply installation, can solve the problem of expressway greening water preferably.But expressway greening also needs to be equipped with the water-saving spray device, to solve the problem of water saving in specific implementation process, investment and various aspects such as easy to use.
Summary of the invention
Technical problem to be solved by this invention provides the expressway greening rainwater water-saving spray device based on PLC, and intelligent degree height is easy to use, small investment.
Solving the technical scheme that technical problem of the present invention adopts is: the roadside is provided with the retaining water source, the water source connects water pump, the husky separator of water, sandstone filter, lamination filter and shower nozzle successively by pipeline, inserted the contactor normally opened contact of PLC controller in the motor incoming line of water pump, the signal input part of PLC controller connects rain sensor.
Concrete technical scheme of the present invention also comprises:
In the motor incoming line of water pump, also inserted the contactor normally opened contact of personal control; and be provided with the contactor normally-closed contact of the protection of reciprocal interlocking in the two the current loop of PLC controller and personal control, the contactor normally opened contact that PLC controller and personal control are located in the motor incoming line of water pump is in parallel.
Be provided with time-delay relay turn-off time in the personal control; its contact is located in the personal control current path; when the personal control control of pump is sprayed, can when arriving, the delay time of setting quit work automatically, play the effect of water receiving and protection water pump.
On the hydraulic pipeline of water pump output, be connected with check valve, can prevent the aqueous reflux of extracting out.On hydraulic pipeline, also be connected with air bleeding valve, can bleed off ducted air, prevent vapour lock.Hydraulic pipeline before the magnetic valve of sandstone filter, lamination filter and shower nozzle is provided with manometer, and is excessive when demonstrating pipeline pressure, then can turn off pipeline, shields.
The water pump operation of this device is divided into manually and automatic control circuit, and rain sensor is connected to the digital module interface of PLC.PLC is connected to by contactor coil on the AC power of 220V, when PLC detect continuous three it does not have the signal that rains, PLC just exports an instruction, contactor coil gets electric, moves the contactor normally opened contact of major loop automatically, water pump operation.Water pump brings into operation, and PLC just picks up counting, if water pump operation 30 minutes, then PLC exports an instruction again, stops water pump operation.When PLC moved, manually the contact of control loop disconnected, and manually control of pump can not moved, and plays the interlock protection effect.Manually control loop is by the state of opening Yu stopping of stop button decision control loop.When manually moving, after time arrival that its time-delay relay turn-off time is set, the disconnection of control contact makes personal control disconnected, and water pump quits work, and the PLC automatically controlled water pump can not move when same personal control moved, and played the interlock protection effect.In the time of water pump operation, the water that water pump is extracted out need pass through check valve, sandstone filter, air bleeding valve, manometer, flange, lamination filter, pressure sensor, detection and control device such as magnetic valve.Behind the water process master control magnetic valve that water pump is extracted out, divide three road discharge pipes, enter ejecting device, each cartridge nozzle is equipped with 6 shower nozzles and 6 ball valves are formed, and shower nozzle is to be controlled by ball valve separately.The length of expressway greening band is 40 meters, and wide is 20 meters, and the effective diameter of shower nozzle is 3.6 meters.Two shower nozzles of each discharge pipe are at a distance of 7.2 meters, and effective range is that 60% diameter according to sprinkler pattern range calculates.Distance between the adjacent shower nozzle of every discharge pipe is 7.2 meters.Can guarantee effectively that the expressway greening band all irrigates no dead angle.In the drilling well of highway correct position, 10 meters of well depth, water pump, suction hose and stem equipment, arm etc. and be 4.8 meters.14.8 meters of total (pumping) heads, the flow of water are 79m 3/ h, the match power of water pump are 5.5kw, the optional 4BA-25 of its model.
The beneficial effects of the utility model:
1, the greenbelt plant can fully absorb moisture, keeps expressway greening U.S..If highway continuous three does not rain more than it, PLC will detect does not have the rainfall signal, and sends an instruction, and water pump operation makes greenbelt keep fully absorbing moisture always.
2, alleviate the greening work personnel labor intensity.During the broiling summer, highway ground is awfully hot, adopts traditional sprinkling waterwheel, and intensity of workers is big.At the hottest weather, adopt the intelligence controlling device of PLC, machinery replaces people's work, can alleviate staff's labour intensity, brings glad tidings for the greening work personnel.
3, save cost.The plant equipment of spraying waterwheel is very expensive, can adopt the Based Intelligent Control electronic apparatus of PLC to replace plant equipment, and cost is very low.
4, the conserve water resource.With the area, Kunming is example, and major part is the weather that does not rain in Kunming 1 year, and water resource is valuable especially.The flow of water is 79m 3/ h, each automatically controlled water pump operation 30 minutes is because the water source is to obtain from highway end hole water, 39.5 tons of then each automatically controlled water pump operation conserve water, 3.5 yuan/ton of water rates, in 1 year continuous three it does not rain and have 30 times, then control the method for operation automatically: conserve water was 1185 tons in 1 year.Manually the control method of operation had 100 times in 1 year, then 1 year conserve water of manual control mode: 3950 tons.Dual mode 1 year altogether can conserve water 5135 tons, and 1 year saves cost is 17972.5 yuan
5, the water source supply abundance.Water supply system is made up of two parts.In the time of rainy day, the rainwater that high mountain flows down flows to the cistern storage through zanjon, in fine day, if well water is not enough, just starts rainwater cistern device.Have abundant water resources, can not cut off the water supply.
