Problems solved by technology

[0003] Most of the water sample collection devices currently used are uncontrollable in the depth of water sample collection in ponds, and the depth of the collected water samples cannot be flexibly adjusted according to the site conditions. Therefore, it is necessary to develop a water sample collection device with adjustable sampling depth, and the structure of the collector is simple. , easy to operate

Embodiment 1

[0020] Such as figure 1 As shown, the pond water sample collection device with adjustable collection depth of the present invention includes a floating plate structure 1, a rope 2 and a water sample collector 3, wherein:

[0021] The middle part of the floating plate structure 1 is provided with a through hole that runs through its top surface and bottom surface. The column 12, the second winding column 13 and the third winding column 14, the first winding column 12, the second winding column 13 and the third winding column 14 are arranged in sequence along the direction from the through hole to the rope fixing column 11, The distance between the first winding post 12 and the second winding post 13 is smaller than the distance between the second winding post 13 and the third winding post 14 .

[0022] There is a scale on the rope 2, the rope 2 passes through the through hole of the floating plate structure, one end is fixedly connected with the rope fixing column 11, and the ...

Embodiment 2

[0027] Such as Figure 1-Figure 2 As shown, the pond water sample collection device with adjustable collection depth of the present invention includes a floating plate structure 1, a rope 2 and a water sample collector 3, wherein:

[0028] The floating plate structure 1 includes an upper floating plate 15, a lower floating plate 16 and a surrounding plate 17. The upper floating plate 15 and the lower floating plate 16 are parallel to each other and there is a gap. and the lower floating plate 16 are fixed; by being provided with the upper floating plate 15 and the lower floating plate 16, the floating plate structure 1 is more stable, avoiding its large shaking and affecting the collection of water samples.

[0029] The middle part of the floating plate structure 1 is provided with a through hole that runs through its top surface and bottom surface. The column 12, the second winding column 13 and the third winding column 14, the first winding column 12, the second winding col...

Abstract

The invention discloses a sampling depth-adjustable pond water sampling device. The device comprises a floating plate structure, a rope and a water sampler, wherein a through hole penetrating the topsurface and the bottom surface of the floating plate structure is formed in the middle part of the floating plate structure; a rope fixing column is arranged on the top surface of the floating plate structure; a first winding column, a second winding column and a third winding column are arranged at a linear position between the rope fixing column and the through hole; the first winding column, the second winding column and the third winding column are sequentially arranged along the direction from the through hole to the rope fixing column; a scale is arranged on the rope; the rope passes through the through hole of the floating plate structure; one end of the rope is fixedly connected with the rope fixing column; the other end of the rope is fixedly connected with the water sampler; andthe buoyancy of the floating plate structure is greater than the gravity of the water sampler full of water. The sampling depth-adjustable pond water sampling device has the advantages that the watersampling with different water depths can be realized by adjusting the length of the rope between the floating plate and the water sampler; and the device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a pond water sample collection device with adjustable collection depth. Background technique [0002] Since 1949, fish farming in ponds has gradually developed to areas other than the Yangtze River and the Pearl River Delta where fish farming is well developed. After 1958, China successfully researched the fully artificial breeding technology of silver carp, bighead carp, grass carp, herring, dace, and round bream, which changed the long-term situation of relying on Zhang to catch natural fry in short supply. In addition, the popularization of advanced fish farming experience, the prevention and control of major fish diseases, and the development and promotion of compound bait have also promoted the expansion of the breeding area and the increase of the output per unit area. China's pond fish farming now ranks first in the world in terms of total output, aquaculture area, and average yield per unit of concentrated contiguous f...
