Moreover, it is an important technical means to monitor runoff/leaching water in the ecological technical fields of non-point source pollution, water and soil conservation and vegetation restoration.
[003] Minerals and trace elements in soil may dissolve in runoff/leaching water. The runoff/leaching water collected unceasingly during a period of time may be split into water samples of any same quantity for testing by way of differentiation and integration, so that a dynamic distribution curve of minerals and trace elements in the local runoff/leaching water can be accurately obtained, thus providing theoretical basis for improving the local ecological system.

[023] S6, the step S5 is repeated until collection of the runoff/leaching water into all the sampling bottles is completed or predetermined collection time expires, and therefore, the sampling of the runoff/leaching water is completed.
[024] The disclosure achieves the following technical effects as compared with the prior art:
[025] The integrating sampling apparatus provided in the disclosure includes a flow concentrating device, a support frame, a tipping box and a rotary collecting device. A partition plate is arranged in the middle of the tipping box to divide the tipping box into two water storage tanks which are exactly the same, thereby ensuring that the water storage capacity of each water storage tank is the same and of a rated value. Water outlets are formed in ends, far away from the partition plate, of the two water storage tanks. At least one water storage tank is provided with a splitting orifice at the center line of the end far away from the partition plate. The flow concentrating device allows the collected runoff/leaching water to flow into any one water storage tank through the diverting orifice. The middle position of the bottom of the tipping box is rotatably connected to the support frame. When the water in the water storage tank reaches the rated value, the tipping box rotates toward the water storage tank. The weight of the water in the water storage tank has a fixed value, and the force acting on the tipping box is the same in magnetite and direction, so that the tipping box rotates at a same speed each time. The angle at which the tipping box rotates each time can be limited by the limiting piece. The bottom plate of the water storage tank is a flat plate, and the lowest portion of the water outlet is not above the inner bottom surface of the bottom plate of the water storage tank with no obstruction effect on the water in the water storage tank flowing out of the water storage tank, so that the water in the water storage tank can be split proportionally each time by the splitting orifice with the same water quantity. The lower end of the splitting orifice is connected to a splitting pipe which can be inserted into a sampling bottle along with the rotation of the tipping box. The water in the water storage tank may not pass through the splitting orifice before the splitting pipe is inserted into the sampling bottle, thereby ensuring that the same quantity of water flows from the splitting pipe into the sampling bottle each time, with the water quantity being denoted as a unit water quantity. The water quantity of one sample is denoted as a standard water quantity. The required number of rotations of the tipping box can be calculated based on the unit water quantity and the standard water quantity, which is denoted as a rated number of rotations. When the tipping box rotates for the rated number of rotations, the rotating disc rotates, thus allowing water samples split by the splitting orifice to be collected into the sampling bottles in sequence. As a result, it is realized that the runoff/leaching water is collected unceasingly during a period of time and split into water samples of any same quantity.
[026] Each of the two water storage tanks is provided with one splitting orifice and the splitting orifice is fixedly connected to one splitting pipe, so that the runoff/leaching water can be split no matter whether the tipping box rotates clockwise or anticlockwise. The splitting pipes on two sides are inserted into the sampling bottles after passing through splitting collecting orifices and then water inlets, so that the split runoff/leaching water is collected into the sampling bottles, thereby ensuring the accuracy of metering and improving the working efficiency of the integrating sampling apparatus.
[027] The integrating sampling method provided in the disclosure can accurately obtain the dynamic distribution curve of minerals and trace elements in the local runoff/leaching water, thus realizing that the runoff/leaching water is collected unceasingly during a period of time and split into water samples of any same quantity.
[028] To explain the technical solution in an example of the disclosure or in the prior art, the accompanying drawings required in the example will be described below in brief.
[029] FIG. 1 is a schematic diagram of an integrating sampling apparatus according to an example of the disclosure.
[030] FIG. 2 is a schematic diagram of a tipping box-support frame connection structure of an integrating sampling apparatus according to an example of the disclosure.
[031] In the drawings, what reference numerals represent are: 1-tipping box, 2-support frame, 3-flow concentrating device, 4-partition plate, 5-splitting orifice, 6-splitting pipe, 7-diverting orifice, 8-flow concentrating orifice, 9-bottom plate of water storage tank, 10-rotating shaft, 11-annular stopper, 12-water inlet, 13-support pillar, 14-split liquid collecting container, -support plate, 16-splitting collecting orifice, 17-water storage tank, 18-water outlet, 19-level ball, 20-bottle holder, 21-sampling bottle, and 22-rotating disc.
[032] All other examples obtained by a person of ordinary skill in the art based on the examples of the disclosure without creative efforts shall fall within the protection scope of the disclosure.
[033] To solve the problems in the prior art, an objective of the disclosure is to provide an integrating sampling apparatus which can split runoff/leaching water collected unceasingly during a period of time into water samples of any same quantity.
[034] The disclosure provides an integrating sampling apparatus. In a specific example of the disclosure, as shown in FIG. 1 and FIG. 2, a flow concentrating device 3 serves to collect runoff/leaching water, and the runoff/leaching water flows into a water storage tank 17 through a diverting orifice 7. A tipping box 1, a support frame 2, a splitting pipe 6 and an annular stopper 11 are symmetric about a rotating shaft 10. The tipping box 1 rotates so that the splitting pipe 6 is inserted into a splitting collecting orifice 16. The runoff/leaching water in the water storage tank 17 flows out of a water outlet 18. An angle of rotation of the tipping box 1 is limited by a limiting piece, so that the tipping box 1 rotates clockwise and anticlockwise at a same and fixed angle. Two water storage tanks 17 of the tipping box 1 are the same in shape and structure, and thus have the same rated value of water storage capacity. When the runoff/leaching water in one water storage tank 17 reaches the rated value, the tipping box 1 tips toward the water storage tank 17. Since the weight of the runoff/leaching water in the water storage tank 17 has a fixed value, the force acting on the tipping box 1 is the same and fixed in magnetite and direction, and therefore, the tipping box 1 rotates clockwise and anticlockwise at a same and fixed speed. When the tipping box 1 tips, the runoff/leaching water in the water storage tank 17 is split proportionally by a splitting orifice 5. Before the splitting pipe 6 is inserted into a sampling bottle 21, the water in the water storage tank 17 may not pass through the splitting orifice 5. Since the tipping box 1 rotates at a fixed angle and a fixed speed and the water storage capacity of the water storage tank 17 is of a rated value, the same quantity of water flows into the sampling bottle 21 through the splitting pipe 6 every time the tipping box 1 rotates. The quantity of water flowing into the sampling bottle 21 through the splitting orifice 5 when the tipping box 1 tips once is measured by a pre-experiment and denoted as a unit water quantity. The water quantity of one sample is denoted as a standard water quantity. The number of rotations of the tipping box 1 when the water collected in one sampling bottle 21 reaches the standard water quantity can be calculated based on the unit water quantity and the standard water quantity and denoted as a standard number of rotations. When the tipping box 1 rotates for the standard number of rotations, a rotating disc 22 rotates, so that water samples split by the splitting orifice 5 can be sequentially collected into the sampling bottles 21 in sequence. The collected water samples are subjected to experiment separately so as to accurately obtain a dynamic distribution curve of minerals and trace elements in the local runoff/leaching water. Thus, it is realized that the runoff/leaching water is collected unceasingly during a period of time and split into water samples of any same quantity.
[035] Specific examples are used herein for illustration of the principles and implementations of the disclosure. A person of ordinary skill in the art can make various modifications to specific implementations and scope of application in accordance with the ideas of the disclosure. In conclusion, the content of the specification shall not be construed as a limitation to the disclosure.
