Detailed Description
The present invention will be described in further detail with reference to specific embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.
As shown in fig. 1, the flood water sample collection device of the present invention includes a temporary reservoir 1, a water sample storage box 17, a control unit 9 and an outer box 10; the temporary water reservoir 1 consists of a stainless steel grid 2, a float switch A4, a float switch B5, an electric butterfly valve A14 and an electric butterfly valve B6, wherein the stainless steel grid 2 is a coarse mesh grid and is mainly used for isolating large-volume foreign matters and preventing the temporary water reservoir from being damaged and blocking pipelines; two float switches are used for detecting high, low water level for the water yield is judged, and float switch has corresponding protection network 3 to provide the protection simultaneously, prevents that the stone from destroying or disturbing the detection. The water sample storage box 17 is detachable and fixed by a limit seat 20 inside the outer box 10, and a water tank induction switch 21 is arranged at the bottom of the outer box 10 and used for sensing whether the water sample storage box 17 is installed or not. The water sample storage box 17 is connected with the electric butterfly valve A14 through the large-caliber connecting hose 15, and only the hose locking ring 16 needs to be loosened during disassembly. The water sample storage box 17 is provided with a pressure type water level gauge 19 which is also detachable, and a protective sleeve 18 is arranged on the pressure gauge.
The outer box body is provided with an operating door right above the water sample storage box, and a box door inductive switch is arranged on the operating door, so that an operator can take away the water sample storage box conveniently. The bottom of the temporary reservoir is connected with a waste water pipeline for draining waste water, and the waste water pipeline is provided with a check valve for preventing the waste water from flowing backwards.
The control unit is connected with a battery pack, is a control center of the whole collector and is used for equipment control and alarm in the collector. The control unit is respectively connected with the float switch, the electric butterfly valve, the water sample storage box, the water tank inductive switch and the box door inductive switch.
The working principle of the device is as follows:
in general, the collector is in a standby state, the electric butterfly valve A is in a closed state, and the electric butterfly valve B is in a certain opening degree. When water flows over the collector, the water enters the temporary reservoir firstly, and as the electric butterfly valve B is in an open state, part of the water flows to the waste water pipeline through the valve and is discharged to the outside. At the moment, if the rainwater is common rainwater, the water entering the temporary water storage tank can be emptied after a period of time, and the next water sample collection is not influenced. If the amount of the instantaneous water entering the temporary water reservoir is larger than the amount of the drained water, the water level in the temporary water reservoir is in a rising state. By detecting the two float switches, the control unit calculates the time from the float switch B to the float switch a of the water level, and judges the speed at which the water level rises. And judging whether the water entering the temporary reservoir is common rainwater or flood according to the water level rising speed.
If the judgement is that the flood collector gets into the water sample collection state, automatically open electric butterfly valve A through the control unit, close electric butterfly valve B, make the water sample of interim cistern enter into water sample storage box, detect the water level of water sample storage box, after the water level reaches the anticipated water level, the collector gets into warning and drainage state, close electric butterfly valve A, open electric butterfly valve B to the maximum aperture, water sample storage box and outside isolated, remaining water is discharged from the waste water pipeline, produce alarm signal, through radio communication, send alarm signal to platform or central station, after the staff received alarm signal, treat that the flood retreats the back, open the operating door, the collector gets into manual operation state. At this time, the operator can select to open the electric butterfly valve A to drain away the redundant water in the connecting hose. Then the soft locking ring is loosened, and the water sample storage box can be taken away after the water level gauge is removed. After the water sample storage box is taken away to the collector, get into no water tank state, can close electric butterfly valve A immediately, electric butterfly valve B is opened to full opening, until the water sample storage box is examined again, just can get into standby state. And when the float switch of the temporary reservoir does not detect the water level, the normal state is recovered, and the temporary reservoir enters a standby state.
The foregoing is a more detailed description of the invention in connection with specific/preferred embodiments and is not intended to limit the practice of the invention to those descriptions. It will be apparent to those skilled in the art that various substitutions and modifications can be made to the described embodiments without departing from the spirit of the invention, and such substitutions and modifications are to be considered as within the scope of the invention.
