Description

A kind of river flood control monitoring device and its construction method
Technical field
The present invention relates to a kind of river flood control monitoring device and its construction methods.
Background technique
Flood control works are for control, defending flood to reduce or remit the engineering that flood loss is built.
Flood control works in the prior art mainly have water blocking, flood discharge and retain three categories, although these flood control measures are most Direct flood control means, but require to put into a large amount of human and material resources and financial resources, and effect might not be fine, simultaneously Due to cannot quickly reduce the water level in river, it is affected caused by urban waterlogging, influence time is long.
Summary of the invention
Present invention aims at provided for deficiency of the prior art a kind of river flood control monitoring device and its The design of the technical solution of construction method, sealing mechanism can be beaten in the case where flood occurring or river water level goes up too fast It opens, so that river water is entered water storage system after solid-liquid separation device separates, so that river water is rapidly entered water storage system and shunted, mitigate Granule foreign in river water can be separated, be prevented by water level rise pressure caused by flood control barricade, solid-liquid separation device Granule foreign results in blockage to flood control monitoring device, improves flood control effect, while the river water shunted through water storage system can follow Ring utilizes, and it is simple to reduce the waste of the water resource construction method step, practical, not only can satisfy different in width river Flood control monitoring, and quick shunting processing directly can be carried out to river water, the water level in river is reduced, prevents from causing urban waterlogging.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme:
A kind of river flood control monitoring device, it is characterised in that: including flood control barricade, sealing mechanism, solid-liquid separation device and Water storage system, flood control barricade are located at the upstream face top on riverbank, and sealing mechanism is connected on flood control barricade, set on the top surface on riverbank It is equipped with water-flowing trough, solid-liquid separation device is provided with below water-flowing trough, solid-liquid separation device connects water storage system by water inlet pipe, Water storage system is located at the inside on riverbank;By the design of flood control barricade, can when flood occurs by river water barrier in river In road, prevent river water reverse irrigation from causing urban waterlogging, the design of sealing mechanism can go up too fast in generation flood or river water level In the case where open, make river water after solid-liquid separation device separates enter water storage system, make river water rapidly enter water storage system into Row shunt, mitigate water level go up the pressure caused by flood control barricade, solid-liquid separation device can by the granule foreign in river water into Row separation, prevents granule foreign from resulting in blockage to flood control monitoring device, improves flood control effect, while being shunted through water storage system River water can recycle, and reduce the waste of water resource.
Further, flood control barricade includes baffle, stiffening plate and guide plate, and stiffening plate is vertically set in qually spaced in the outer of baffle On side, spaced set has at least three guide plates from top to bottom between two neighboring stiffening plate, and baffle can play blocking The effect of river water, stiffening plate improve the installation strength of baffle, can resist bigger flood impact, and guide plate can incite somebody to action on quickly The river water to rise is guided to water-flowing trough, improves the shunting efficiency of river water.
Further, first sensor and second sensor are provided on the lateral surface of baffle, first sensor is located at second The lower section of sensor, first sensor and second sensor are and control room, first sensor are used for the effect of monitoring and warning, the Two sensors then play alarm function, convenient for opening sealing mechanism at the first time, the shunting of river water are realized, to reduce in river Water level.
Further, guide plate side directed downwardly is provided with arc guide groove, and arc guide groove can play the role of water conservancy diversion, make river Water rapidly enters solid-liquid separation device, while after river water and baffle collide, and prevents river water from entering road surface, and then influence city The drainage system in city.
Further, sealing mechanism includes hydraulic cylinder, water fender and telescopic rod, and hydraulic cylinder is set in qually spaced in baffle On medial surface, it is equidistantly provided with positioning box on the lateral surface of baffle, is arranged fluted on riverbank, groove is connected to water-flowing trough, Water fender limits in groove, and water fender connects hydraulic cylinder by telescopic rod, and telescopic rod runs through positioning box, passes through hydraulic oil It is mobile that cylinder can drive telescopic rod, and then water fender can be driven mobile, makes the river water higher than sealing mechanism directly through solid-liquid point Structure of disembarking enters water storage system, and groove can play position-limiting action to water fender, move horizontally water fender.
Further, solid-liquid separation device includes being separated by solid-liquid separation bucket and training for sediment pipe, is separated by solid-liquid separation bucket and is uniformly arranged on water-flowing trough Bottom surface on, and be connected to water-flowing trough, be separated by solid-liquid separation that bucket is tilted to be arranged in parallel at least two filter screens, the connection of training for sediment pipe is met The water surface and separation of solid and liquid bucket, and training for sediment pipe is located at the height of upstream face lower than the height for being separated by solid-liquid separation bucket junction, separation of solid and liquid Bucket can converge river water, improve the speed of water flow, and the solid particle polluter in river water can be filtered by filter screen, And be discharged by training for sediment pipe, improve the shunting efficiency of river water.
Further, be separated by solid-liquid separation the bottom end connection water inlet pipe of bucket, be horizontally disposed between the two neighboring water inlet pipe in left and right have it is auxiliary Assistant director of a film or play's flow tube is provided with third valve on auxiliary draft tube, by the design of auxiliary draft tube can by adjacent water inlet pipe into Row shunts, and reduces the water delivery pressure of single water inlet pipe, extends the physical life of water-supply-pipe, third valve can control water inlet pipe it Between water flow distribution.
Further, the side that training for sediment pipe is located at upstream face is rotatably connected to capping, capping can solid-liquid separation device not Stopped when work, since the pressure of river water realizes the sealing of training for sediment pipe, when solid-liquid separation device work, due to solid-liquid point Pressure from water in struggling against is greater than the pressure of water in external river, therefore capping is opened, and training for sediment pipe is discharged in solid particle polluter.
Further, water storage system includes water tank, and water tank horizontal homogeneous is arranged in riverbank, two neighboring water tank it Between be provided with major flow duct, water inlet pipe is connected to above the trailing flank of water tank, is provided with municipal administration below the leading flank of water tank Drainpipe, municipal drain are connected to city planting ductwork, and the first valve is provided on municipal drain, is arranged on the bottom surface of water tank There is groundwater drain, groundwater drain is connected to ground water regime, and the second valve, water storage are provided on groundwater drain Case can store river water, and be allocated by major flow duct, improve the processing capacity of entire flood control monitoring device, storage River water after depositing can be shunted by municipal drain and groundwater drain, convenient for the recycling of river water, reduce water The waste of resource.
