Technical Field
[0001] The utility model relates to the technical field of water body sampling, and particularly relates to a plankton sampler. Background Technique
[0002] While remarkable achievements have been made in water pollution prevention and control work, more and more researchers have noticed that the problem of water ecosystem imbalance still exists. Aquatic organisms are the main body of the water ecosystem, and a healthy and complete water ecosystem is a state where organisms and various environmental elements that maintain their survival reach harmonious coexistence and stable development. The existing methods for collecting plankton in water mainly use plankton collection nets. Although plankton collection nets can collect a large number of plankton at one time, due to the certain differences in the types and sizes of plankton existing in the water body, the collected plankton mixed in the same plankton collection net still need to be classified and processed later in order to accurately understand and master the types and quantities of plankton in the water body, and the sampling is relatively cumbersome. Content of the Utility Model

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.
[0020] As Figures 1-4 shown, a plankton sampler includes a sampling box 1. A liquid inlet pipe 2 and a liquid outlet pipe 3 are respectively arranged on the side wall of the sampling box 1 from top to bottom. A controller 4 for controlling the operation of the liquid inlet pipe 2 and the liquid outlet pipe 3 is arranged at the top of the sampling box 1. A liquid storage cavity 5 communicating with the liquid inlet pipe 2 and the liquid outlet pipe 3 respectively is opened in the inner cavity of the sampling box 1. A collection net 6 is successively connected in the inner cavity of the liquid storage cavity 5 between the liquid inlet pipe 2 and the liquid outlet pipe 3 from top to bottom;
[0021] Among them, the apertures of the collection nets 6 arranged from top to bottom decrease in sequence to collect plankton of different sizes.
[0022] In this device, plankton of different types in the sampled water body are collected through collection nets with different apertures, which is convenient for classifying plankton during one sampling, so as to accurately analyze the types of plankton in the water body, and further contribute to evaluating the biodiversity and ecological health of the water body.
[0023] A fixing point for fixing a rope is also arranged at the top of the sampling box of this device. During use, it can be directly fixed on the fixing point through a telescopic device and then put into the water, or carried on a floating object. Among them, the length of the rope dropped can be used to sample water bodies at different depths.
[0024] The controller 4 can be wirelessly controlled, and the control program has been set in advance.
[0025] Specifically, as Figures 1-4 shown, several sockets 7 are successively opened on the surface of the sampling box 1 from top to bottom. Each socket 7 communicates with the liquid storage cavity 5. A frame 8 is inserted into each socket 7. The collection net 6 is arranged in the inner cavity of the frame 8.
[0026] This can facilitate taking out the plankton collected in the collection net 6. After drying the collected plankton, it is possible to better analyze the types and distribution of plankton in the sampled water body.
[0027] Since the collection net 6 is adopted in a pulling manner, it is necessary to seal between the frame 8 and the liquid storage cavity 5, and the collection net 6 can also be kept stable during installation.
[0028] Specifically, as Figures 1-4As shown, guide bars 9 are provided on both side walls of the frame-shaped rack 8 along their own length directions, and guide grooves 10 for inserting the guide bars 9 are formed in both the inner cavities of the socket 7 and the liquid storage cavity 5.
[0029] Through the cooperative connection of the guide bars 9 and the guide grooves 10, it can ensure that the frame-shaped rack 8 moves along a straight line, thereby ensuring the tightness between the frame-shaped rack 8 and the liquid storage cavity 5, and at the same time, it can also play a supporting role for the frame-shaped rack 8.
[0030] The main function of the collection net 6 is to collect plankton, and the collection net 6 should also be able to be taken out of the socket 7 smoothly.
[0031] Furthermore, as Figures 1-4 shown, a support rod 11 is horizontally arranged at the middle position of the frame-shaped rack 8, and the middle area of the collection net 6 is connected to the support rod 11 to form a V-shaped shape of the collection net 6.
[0032] This can make the collected plankton concentrate in the middle area of the collection net 6, thus facilitating subsequent centralized treatment.
[0033] During the process of liquid inlet and outlet, the inlet pipe 2 and the outlet pipe cannot work simultaneously, and they can release or absorb liquid under the action of external force.
[0034] Specifically, as Figures 1-4 shown, one end of each of the inlet pipe 2 and the outlet pipe 3 extending into the liquid storage cavity 5 is connected with a pump body 12, the other end of each pump body 12 extends into the liquid storage cavity 5 through a pipeline, and the pump body 12 is electrically connected to the controller 4.
[0035] The pump body 12 located in the inlet pipe 2 is used to introduce the external water body into the liquid storage cavity 5, and the pump body 12 located in the outlet pipe 3 is used to discharge the liquid in the liquid storage cavity 5 to the outside. The discharged liquid is subjected to centralized treatment, and finally, the health condition of the sampled water body is analyzed based on the volume of plankton and the discharged water body through the collection net 6.
[0036] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
