Description
Technical field
The present invention relates to the portable sheet flow sampler of a kind of drawer type and the method for sampling thereof, belong to slope runoff Sampling techniques field.
Background technology
At present, manual artificial sample is mainly taked for the sampling of slope runoff in Chinese most of area, and condition of work is poor, inefficiency, and error is comparatively large, can not realize the information such as the water yield size of real time record slope runoff, speed speed.Although some company has been proposed part water-quality sampler both at home and abroad at present, but existing water-quality sampler can not meet the sampling request of slope runoff, and ubiquity heaviness is not portable, manufacturing cost is high, sampling pattern is single and the shortcoming such as the built-in and inconvenient extraction of sampling bottle and placement.Major part sampling thief adopts peristaltic pump to connect rotating head and feeds water, and they exist some sealing problems and corrosion problems.In addition, existing collector only has collecting part, and function singleness is not suitable for intellegent sampling.
Summary of the invention
In order to overcome the drawback of existing water-quality sampler, the object of the present invention is to provide one to be convenient for carrying, automatically, sampling pattern can according to the portable sheet flow sampler of the self-adjusting drawer type of actual flow size and the method for sampling thereof, save manpower to reach, gather effect that is convenient, Real-Time Monitoring, ensure reliability and the accuracy of water sampling, be convenient to correctly judge water quality condition.
To achieve these goals, the technical solution used in the present invention one is: the portable sheet flow sampler of a kind of drawer type, be made up of water-storing device and harvester, described water-storing device comprises installation tank on the support frame and is arranged on the stirrer in tank, what described support frame is also provided with driving tank rotary dumping topples over motor, the water inlet of described tank is provided with flow sensor, is also provided with level sensor in described tank; Described harvester comprises block and is positioned at the case lid directly over block, electronic screw mandrel guide rail is installed in described case lid, described electronic screw mandrel guide rail is provided with square crossing and the distributing pipe valve sets be slidably matched, be provided with the drawer of built-in many row's sampling bottles in described block, row's water filling mouth of pipe of described distributing pipe valve sets aims at the arbitrary mining sample bottleneck in drawer; The water delivering orifice of described tank through external water delivery tubes connection to the import of peristaltic pump, described wriggling delivery side of pump to the import of distributing pipe valve sets through built-in water delivery tubes connection, described flow sensor, level sensor, is toppled over motor, the stirring motor of stirrer, the drive motor of electronic screw mandrel guide rail, the solenoid valve of distributing pipe valve sets and the drive motor of peristaltic pump and is all electrically connected to control device.
Further, described in topple over motor, stirring motor and peristaltic pump drive motor be all furnished with the power source being controlled break-make by control device, described power source is battery or external power supply.
Further, described control device is the single-chip microcomputer be arranged in control box, and described control box is arranged in case lid.
Further, described control device is electrically connected with IO interface, memory cards, wireless communication module, switch governor module, power module and display module.
Further, described peristaltic pump is arranged on case lid.
Further, described case lid and the upper and lower releasable connection of block, described support frame and the releasable connection of block left and right.
Further, described block is provided with the fair water fin be positioned at above drawer, described fair water fin is distributed with multiple funnel hole leading to corresponding sampling bottle respectively.
Further, described block bottom side is provided with universal wheel, is provided with pumping rod on front side of described block.
Further, before and after described drawer, side is provided with handle.
To achieve these goals, the technical solution used in the present invention two is: a kind of slope runoff method of sampling, adopts the portable sheet flow sampler of drawer type as above, and carries out according to the following steps:
(1), after the rainwater on domatic flows down, introduce in tank with a drainage catheter, flow sensor detects rainwater flow, and sends flow signal to control device;
(2) after rainwater enters tank, control device starts stirrer, stirring motor drive impeller, and make the rainwater containing silt obtain uniform stirring, the rainwater be evenly distributed for follow-up peristaltic pump pumps is prepared;
(3) when the water in tank reaches set amount, control device starts peristaltic pump, peristaltic pump draws the water in tank by external water delivery conduit, distributing pipe valve sets is sent gathering the water come into by built-in water delivery conduit, water suction is just stopped after being drawn onto the water yield filling a sampling bottle, start and topple over motor, remaining rainwater is outwelled, avoid remaining the sampling precision that rainwater affects next sampling bottle;
(4) distributing pipe valve sets is moved to the top of first row sampling bottleneck by control device by electronic screw mandrel guide rail, waits for water filling; The solenoid valve of distributing pipe valve sets opened successively singly by control device, carries out water filling successively to each sampling bottle; After upper row's water filling terminates, distributing pipe valve sets is moved to the top of next row sampling bottleneck by electronic screw mandrel guide rail, again carries out water filling; By that analogy, until after all sampling bottles collections of drawer, by drawer pull out, sampling bottle is all taken out, change sky sampling bottle, continue sampling.
Compared with prior art, the present invention has following remarkable advantage: the portable sheet flow sampler of this drawer type can realize the function of water level detecting in rainwater flow detection and tank by flow sensor and level sensor, by stirrer and topple over motor can realize silt in rainwater be uniformly distributed and topple over residue ponding function, by by drawer, the drawer type portable device of block and case lid composition realizes convenient carrying, block is separated is convenient to the taking-up of sampling bottle and the function of placement, overcome region and the time restriction of artificial sample, round-the-clock full-automatic sampling is carried out in the place being movable to required sampling, highly versatile, and reach saving manpower, gather convenient, that acquisition water sample is convenient, guarantee gathers water sample accuracy object, whole compact equipment, coordinate closely, good airproof performance, contributes to the carrying out of rainfall detection and research soil and water conservation work.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
