It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0035] As Figures 1 to 2 shown, a multi-level water level water sample detection and sampling device for a reservoir of the present invention includes:

[0036] A pumping cylinder 1 is vertically installed with four groups of water outlet pipes 2. A water inlet pipe 3 is also provided on the pumping cylinder 1 corresponding to each group of water outlet pipes 2. A driving box 6 is fixedly installed on the pumping cylinder 1, and the driving box 6 is used to control the corresponding water outlet pipe 2 and water inlet pipe 3 to perform pumping operations respectively;

[0037] Among them, each group of water inlet pipes 3 is connected with a hose 8. The input ends of the four hoses 8 are all installed on an adjustment box 7, and the adjustment box 7 is used to adjust the relative height of the input ends of the four hoses 8. Each group of water outlet pipes 2 is respectively communicated with a water sample collection bucket at different water layers;

[0038] Specifically, in this embodiment, the water outlet pipe 2 and the water inlet pipe 3 at the same height are coaxial, and the axis is perpendicular to the axis of the pumping cylinder 1. The driving box 6 is a waterproof and sealed box, and underwater operation will not affect the use of the transmission mechanism. The branch pipe 5 and the water outlet pipe 2, and the water inlet pipe 3 and the hose 8 are all connected by flange plates or threads, which can effectively ensure the sealing performance of the equipment. The devices such as the pumping cylinder 1 and the adjustment box 7 are sunk into the reservoir. According to the water layer requirements to be collected, the input ends of the four hoses 8 are adjusted to the corresponding water layer heights through the adjustment box 7. Then, the driving box 6 is started, and the water outlet pipe 2 and the water inlet pipe 3 at the same water layer are connected in sequence to automatically sample the water samples in the reservoir from top to bottom, which can effectively reduce the cross of water samples and the situation of affecting the water sample detection results, and improve the accuracy of water sample analysis.

[0039] When the influence of water sample cross on the detection accuracy is not significant, the water samples can be transported in sequence through the conveying pipeline 4. Four branch pipes 5 are arranged on the conveying pipeline 4 corresponding to the four water outlet pipes 2, and the four branch pipes 5 are respectively communicated with the four water outlet pipes 2. The output end of the conveying pipeline 4 is communicated with an external water sample bucket. To facilitate the overall lifting or lowering of structures such as the pumping cylinder 1, the conveying pipeline 4, and the adjustment box 7, the pumping cylinder 1, the conveying pipeline 4, and the adjustment box 7 are all fixedly installed on the base, and a lifting ring 35 is also fixedly installed on the driving box 6, as Figure 2 shown, where the lifting ring 35 is threadedly connected to the driving box 6.

[0040] The specific structure inside the pumping cylinder 1 is as Figures 3 to 7 shown. An inner cylinder 9 is coaxially and fixedly installed inside the pumping cylinder 1. Four pumping chambers 10 are uniformly arranged inside the inner cylinder 9. A through hole 11 is penetrated through the outer wall of each pumping chamber 10, and the through hole 11 is communicated with the coaxial water outlet pipe 2 and water inlet pipe 3. A main shaft 12 is coaxially and rotatably installed inside the inner cylinder 9. Four turbines 13 are fixedly sleeved on the main shaft 12, and the four turbines 13 are respectively located in the four pumping chambers 10. A first motor 14 is fixedly installed on the inner cylinder 9 to drive the main shaft 12 to rotate along its own axis;

[0041] Further, a middle cylinder 15 is rotatably installed between the pumping cylinder 1 and the inner cylinder 9. The outer wall of the middle cylinder 15 fits with the inner wall of the pumping cylinder 1, and the inner wall of the middle cylinder 15 fits with the outer wall of the inner cylinder 9. A first radial hole 16, a second radial hole 17, a third radial hole 18, and a fourth radial hole 19 are penetrated through the middle cylinder 15. The first radial hole 16, the second radial hole 17, the third radial hole 18, and the fourth radial hole 19 respectively correspond to the through holes 11 at different heights. Among them, the axes of the first radial hole 16, the second radial hole 17, the third radial hole 18, and the fourth radial hole 19 are in a circular array in the top view, and the included angle between adjacent two axes is 45°;

[0042] In this embodiment, by driving the middle cylinder 15 to rotate along its own axis, the first radial hole 16 is aligned with the through hole 11 at the same height. As a result, the second radial hole 17, the third radial hole 18, and the fourth radial hole 19 cannot be aligned with the through hole 11 at the same height. That is to say, only the pumping chamber 10 at the first radial hole 16 can perform the pumping operation at this time. Then, start the first motor 14 to drive the main shaft 12 and the turbine 13 to rotate. Under the connection effect of the first radial hole 16, the water sample of this water layer is conveyed to the water sample collection bucket via the water inlet pipe 3 and the water outlet pipe 2 by using the turbine 13 rotating at high speed. After collecting the water sample of this water layer, drive the middle cylinder 15 to rotate 45° along its own axis to align the second radial hole 17 with the through hole 11 at the same height. At this time, the pumping chambers 10 where the other three groups of radial holes are located cannot perform the pumping operation, so that the pumping chamber 10 where the second radial hole 17 is located performs the pumping and sampling. Repeating the above process can perform the sampling operation on different water layers. The structure is simple and the operation is stable, which can effectively avoid the situation of water sample cross between different water layers.

[0043] Specifically, as to how to drive the middle cylinder 15 to rotate along its own axis, as Figure 3 and Figure 7 shown, a mounting disk 20 is fixedly installed on the inner cylinder 9, a gear 21 is coaxially and fixedly sleeved on the middle cylinder 15, a second motor 22 is fixedly installed on the mounting disk 20, a driving gear is arranged at the output end of the second motor 22, and the driving gear is meshed and connected with the gear 21. In this embodiment, by starting the second motor 22, the middle cylinder 15 is driven to rotate along its own axis under the transmission effect of the driving gear and the gear 21. Among them, the second motor 22 adopts a servo motor.

[0044] In order to facilitate the assembly of the inner cylinder 9 and its internal mechanism during the equipment production process, as Figure 6 shown, the inner cylinder 9 adopts a split structure for splicing and fixing.

[0045] As a specific embodiment of the above technical solution, as Figures 8 to 10 shown, the adjustment box 7 includes a box body 23 and four groups of mounting seats 25. A strip-shaped groove 24 is vertically penetrated through the box body 23. The four groups of mounting seats 25 are all slidably installed in the box body 23. Four groups of hoses 8 are respectively fixedly installed on the four groups of mounting seats 25, and the four groups of hoses 8 are all slidably installed in the strip-shaped groove 24;

[0046] Specifically, a slider 33 is fixedly installed on the inner wall of the box body 23, and a slide rail 34 is fixedly arranged on each mounting seat 25. The slide rail 34 is slidably installed on the slider 33. At the same time, a guide roller 26 is rotatably installed inside the box body 23. The outer wall of the guide roller 26 is provided with a first guide groove 27, a second guide groove 28, a third guide groove 29 and a fourth guide groove 30. The first guide groove 27 and the fourth guide groove 30 are symmetrical, the second guide groove 28 and the third guide groove 29 are symmetrical, and the four guide grooves are distributed in a fan shape. The first guide groove 27, the second guide groove 28, the third guide groove 29 and the fourth guide groove 30 are all spiral structures, and the starting and ending points of the above four guide grooves have the same included arc angle corresponding to the horizontal plane. A waterproof motor is arranged inside the box body 23 for driving the guide roller 26 to rotate along its own axis. And a guide post 31 is fixedly arranged on each mounting seat 25. The four guide posts 31 are respectively slidably installed in the first guide groove 27, the second guide groove 28, the third guide groove 29 and the fourth guide groove 30;

[0047] In this embodiment, by starting the waterproof motor to drive the guide roller 26 to rotate along its own axis, under the action of the four guide grooves, the four mounting seats 25 are respectively driven to move synchronously relatively closer or relatively farther away, so as to realize the adjustment of the height of the input end of the hose 8 and achieve the purpose of sampling different water layers. A filter tip 32 is installed at the input end of each hose 8.

[0048] For a multi-level water level water sample detection and sampling device for a reservoir and its use method of the present invention, the installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0049] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
