Most of the existing devices for detecting the water quality environment can only detect one underwater position point simultaneously. When the water quality environment under different water depths needs to be known, the water quality environment can be measured repeatedly, and the efficiency is low. In order to solve the problem that the existing device can only detect one underwater position point and has low detection efficiency, the embodiment provides a device for rapidly measuring the water quality environments of different water depths of a water body in a culture pond, as shown in the accompanying drawings 1 and 2. The device comprises a sampler 1, a detection unit 2 and an air pump 3. Wherein, the sampler 1 can simultaneously collect water samples of different water depths of the water body. The detection unit 2 automatically detects a plurality of water samples in the sampler 1 to obtain water quality environmental parameters of different water depths, thereby greatly improving the detection efficiency. Air pump 3 is used for injecting into gas in sampler 1, increases the pressure in sampler 1, realizes quick water sample discharge and washes carrying out the bubble in sampler 1, reduces impurity deposition in sampler 1.

Specifically, the sampler 1 is hollow cylindrical as a whole, has two closed ends, and is formed by combining and processing plastics such as a transparent PMMA sheet/pipe, a transparent PC sheet/pipe, and the like. The height of the sampler 1 should be greater than the depth of the water body in the culture pond so that the upper end of the sampler 1 is exposed outside the water body. Along the height direction of sampler 1, the internal space of sampler 1 may be divided into N independent sampling chambers 11 (N is an integer of 1 or more) and a buffer chamber 12 from bottom to top. The volumes of the N sampling chambers 11 are the same or different, i.e., the heights of the N sampling chambers 11 are the same or different. Each of the sampling chambers 11 communicates with the buffer chamber 12 through a communicating pipe 13, wherein the communicating pipe 13 between the buffer chamber 12 and the adjacent sampling chamber 11 is replaced by a communicating hole. Therefore, the N sampling cavities 11 are independent from each other after the structure is adopted, but each sampling cavity 11 is communicated with the buffer cavity 12, so that the internal pressure and the external pressure are balanced. As shown in fig. 2 and 3, taking the water depth of 160cm as an example, 5 sampling cavities 11 with the same volume are provided in the present embodiment, and the height of each sampling cavity is 30cm. A sampling hole 14 is arranged on the arc-shaped side wall of each sampling cavity 11 along the radial direction of the sampler 1. The sampling hole 14 is a round hole or a square hole, the size is phi 3mm to 5mm or 3 to 5mm x 3 to 5mm, and the lower edge of the inner wall of the sampling hole 14 is tangent to or flush with the bottom surface of the corresponding sampling cavity 11, so that the water sample collected in the sampling cavity 11 can be discharged basically and completely. Meanwhile, a rubber plug 15 is fittingly mounted on each sampling hole 14. Each rubber stopper 15 is fixed by a separate cord 16, or N rubber stoppers 15 are fixed on a cord 16, and one end of cord 16 is fixed on the top of sampler 1. As shown in the attached drawing 1, 5 rubber stoppers 15 are all fixed on one rope 16, and the rope 16 is pulled forcibly, so that the rubber stoppers 15 can be pulled out from the sampling holes 14, the sampling cavity 11 is communicated with the outside, and a water sample is collected. An exhaust pipe 17 and an intake pipe 18 are arranged near the top of the arc-shaped side wall of the buffer cavity 12, and valves (not shown in the figure) are arranged on the exhaust pipe 17 and the intake pipe 18. The vent tube 17 may allow each sampling cavity 11 to be vented to the outside atmosphere so as not to interfere with water sample collection. The air intake pipe 18 is connected to the air pump 3.

Further, in order to enable the sampler 1 to rapidly extend into the water body and maintain the vertical state, a counterweight (not shown in the figure) is arranged at the lower end of the sampler 1.

In this embodiment, when collecting the water sample of different water depths, open the valve on the blast pipe 17, earlier with sampler 1 vertical insertion breed the pond in, the lower extreme of sampler 1 supports and breeds the bottom of the pond. Pulling the cord 16 and pulling out the rubber stopper 15. Water of different water depths enters the corresponding sampling cavity 11 from the sampling hole 14. Because each sampling cavity 11 is independent and is communicated with the buffer cavity 12 and the external atmosphere, the water sample collection cannot be influenced by the gas retained in the sampling cavity 11. After the test is accomplished, if want the visual observation water sample, close the valve on the blast pipe 17, take out fast or vertical quick taking out after 1 slope of sampler, then cover rubber buffer 15 fast, then can carry out the visual observation.

Meanwhile, the leads between the dissolved oxygen sensor 24, the pH sensor 25, the temperature sensor 26, the inorganic phosphorus detector 27 and/or the inorganic nitrogen detector 28 and the corresponding N probes are arranged via the corresponding communicating tubes 13, i.e., the communicating tubes 13 play a role of balancing the sampling chamber 11 with the atmospheric pressure on the one hand and a role of lead guiding on the other hand.
