[0002] Plankton is aquatic organisms suspended in water bodies, mainly composed of phytoplankton and zooplankton. It is an important component of aquatic ecosystems and the main component of aquatic ecosystem productivity. It plays an important role in maintaining the balance of aquatic ecosystems and the normal progress of ecological processes.

[0003] Therefore, the study of plankton can help us understand the situation of aquatic ecology. In order to obtain plankton in the corresponding waters, a plankton collection device is used to sample the corresponding waters. However, the existing plankton collection device does not have the function of measuring the depth of the water body during sampling; therefore, when sampling, the depth of the collection device is usually lowered based on experience, which makes it impossible to accurately know the depth of the water body where the sample is located, resulting in errors in the research results.

[0025] In order to enable those skilled in the art to better understand the technical solution in the present application, the technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present application.

[0026] Embodiment 1:

[0027] like Figure 1-4 As shown, a water ecology monitoring sampling device can be used to collect plankton in water bodies. The sampling water depth can be more than 1 meter. The structure used includes a sampling bucket 1, a support rod 9, a sampling bottle 3, a drain valve 4, an ultrasonic sensor 6 and a controller 2. The sampling bucket 1 is provided with an inlet end at the top, an outlet end at the bottom, and a water filter on the side. The support rod 9 is connected to the sampling bucket 1 through at least three pull ropes 8. One end of the sampling bottle 3 is connected to the outlet end of the sampling bucket 1; one end of the drain valve 4 is connected to the other end of the sampling bottle 3. The ultrasonic sensor 6 is detachably connected to the other end of the drain valve 4; the controller 2 has a display screen and is connected to the ultrasonic sensor 6 for communication.

[0028] The ultrasonic sensor 6 is used to measure the depth of the water body. When in use, when the ultrasonic sensor contacts the surface of the water body, the ultrasonic sensor is started, and the ultrasonic sensor transmits the monitored water body depth information to the controller, which is displayed on the display screen after being analyzed and processed by the controller. The display screen may be provided with an initial module for displaying the water body depth obtained by initial ultrasonic monitoring and a display change module for displaying the change in water body depth when the ultrasonic wave moves in the water body. It is understandable that the depth difference is obtained by subtracting the value displayed on the display change module from the initial water body depth on the display initial module. It should be noted that the height of the sampling structure of the utility model can be from the top surface of the sampling bucket to the measuring surface on the ultrasonic sensor for measuring the water body depth. The water body depth where the top surface of the sampling bucket is located is the depth difference minus the height of the sampling structure of the utility model.

[0029] The sampling bottle can be a transparent structure, which makes it easy to check the collected plankton.

[0030] One connection between the sampling bottle and the drain valve is: an external thread is provided on one end of the sampling bottle connected to the drain valve, and correspondingly, the drain valve is provided with an internal thread. When connecting, a raw tape can be wrapped around the external thread of the sampling bottle to improve the airtightness of the connection between the sampling bottle and the drain valve.

[0031] It should be noted that the sampling bucket is immersed in the water body. During the upward pulling process, the water body and the floating microorganisms contained in the water body enter the sampling bucket from the inlet end. The side of the sampling bucket can filter water, and the plankton is retained in the sampling bucket. During the rising process of the sampling bucket emerging from the water surface, the plankton in the sampling bucket gradually concentrates on the sampling bottle. When the sampling bottle emerges from the water surface, the plankton in the sampling bucket concentrates on the sampling bottle, completing the collection of plankton in the water body.

[0032] It is understandable that the sampling bucket is connected to the support rod through a plurality of pull ropes, and the support rod can support the sampling bucket to be suspended vertically.

[0033] Collection working method:

[0034] Sampling work: The holding support rod 9 slowly lowers the sampling bucket 1, and when it descends until the ultrasonic sensor 6 touches the water surface, the controller 2 controls the ultrasonic sensor 6 to start, and the ultrasonic sensor 6 starts to monitor the depth of the water body. At this time, the total depth of the water body monitored by the ultrasonic sensor 6 is displayed on the display initial module of the display screen, and then the sampling bucket 1 is slowly released while observing the change of the water body depth displayed on the display change module on the display screen. When the value on the display initial module minus the value on the display change module minus the height of the sampling structure is equal to the required sampling depth, stop lowering the sampling bucket 1, and stay for a while (such as 5, 10 minutes, etc.), and then slowly extract the sampling bucket 1 upwards. When the sampling bucket 1 is exposed to the water surface, the side of the sampling bucket 1 can filter water. Therefore, the water in the sampling bucket is discharged, and the plankton is retained in the sampling bucket. As the sampling bucket continues to rise, the sampling bottle gradually approaches the water surface, and the plankton in the sampling bucket continues to gather toward the sampling bottle. When the sampling bottle is exposed to the water surface, the plankton in the sampling bucket falls into the sampling bottle.

[0035] Collection work: remove the ultrasonic sensor 6 from the drain valve 4, then open the drain valve 4, unload the sample in the sampling bottle into the sample collection bottle, and store it properly, thus completing the collection of plankton in the water body.

The number of the fixing members can be 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or 13, etc. The fixing members can fix the partition net on the top of the sampling bucket, so that the partition net effectively blocks branches, leaves, weeds and other debris from entering the sampling bucket.

When the partition net and the sampling bucket are connected by a pin, the partition net and the sampling bucket can be detachably connected. When the partition net needs to be installed, the partition net is covered on the top of the sampling bucket, and then the partition net and the sampling bucket are connected by the pin, so that it is easy to install and remove.
