Description

Technical Field

[0001] This utility model relates to the field of water ecological environmental protection, and in particular to an automated plankton collection device. Background Technology

[0002] Plankton is an important component of aquatic ecological monitoring, but current plankton nets primarily rely on manual harvesting. Invention patent publication number CN 108174829 A discloses a plankton collection device, which includes a suspension device, a collection net, and a sample collection device. The suspension device and the collection net are detachably connected, and the collection net and the sample collection device are connected by a snap-fit ​​mechanism. Here, the suspension device is a telescopic rod, with a nut welded to a specific position on the collection net. The telescopic rod is threadedly connected to the collection net. Using a telescopic rod makes operation more stable, reduces disturbance to bottom sediment, and results in samples with lower sediment content.

[0003] Using telescopic poles to suspend collection nets allows for convenient collection of plankton from a designated area. However, in the environmental field, the collection of these plankton is not based on the amount collected, but rather on a set time, such as 5 minutes. Because it takes 5 minutes to collect them, manual harvesting may cause people to forget the time, resulting in the collected plankton samples not objectively reflecting the state of plankton in the water, and causing discrepancies between the monitoring results and actual practice. Utility Model Content

[0004] This invention addresses the shortcomings of current plankton collection devices, which only focus on collecting plankton and cannot control the time of plankton collection, thus causing deviations in environmental monitoring results. It provides an automated plankton collection device that stops collecting plankton according to a set time during the collection process.

[0005] The technical solution of this utility model is: an automated plankton collection device, comprising a plankton net and an automatic net casting mechanism. The automatic net casting mechanism includes a support rod and a net casting track. The net casting track is supported by the support rod and extends towards the target water surface for plankton collection. The plankton net is suspended in the water below the net casting track by a slider. An electric trolley is provided on the net casting track to drive the slider to slide along the net casting track. The electric trolley drives the plankton net to collect plankton in the target water surface according to a set time.

[0006] Furthermore, in the aforementioned automated plankton collection device: the net-casting track is in the shape of an "∞", and the time taken for the electric trolley to drive the slider to complete one revolution along the net-casting track is the required set time.

[0007] Furthermore, in the aforementioned automated plankton collection device, the required setting time is 5 minutes.

[0008] Furthermore, in the aforementioned automated plankton collection device, the support rod is a telescopic rod.

[0009] Furthermore, in the aforementioned automated plankton collection device, a timer and a buzzer are also installed on the support rod. The timer is connected to the buzzer, and once the timer expires, it controls the buzzer to sound.

[0010] Furthermore, in the aforementioned automated plankton collection device: the support rod and the net-casting track are connected by a connecting rod; the connecting rod is a 1-3m long metal rod with a built-in battery; the battery supplies power to the electric trolley through wires.

[0011] Furthermore, in the aforementioned automated plankton collection device, a plankton recovery device is provided in the plankton net for recovering plankton.

[0012] This invention employs an automatic net-casting device that stops casting once the allotted time is up. This overcomes the shortcomings of current plankton collection devices, which only focus on collecting plankton and cannot control the timing of plankton harvesting, thus causing deviations in environmental monitoring results.

[0013] In addition, the main advantage of this invention is that it saves labor. Originally, it required manual labor to draw an "∞" shape in the water with a plankton net for 5 minutes to concentrate and capture plankton in the water. This process was very laborious and tiring. Now, an electric slider is used to replace manual drawing of the "∞" shape, which saves labor.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0016] Figure 2 This is a schematic diagram of the automated planktonic collection device according to Embodiment 2 of this utility model. Detailed Implementation

[0017] This embodiment is an automated plankton collection device, such as... Figure 1As shown, in practical applications, it is generally used to catch plankton along the shore of water bodies. It can also be placed on a boat, which can be rowed to a suitable location in a lake or reservoir to catch plankton in the middle of the lake or reservoir. In this embodiment, an automated plankton collection device includes a plankton net 1 and an automatic net casting mechanism. The automatic net casting mechanism includes a support rod 2 and a net casting track 3. The net casting track 3 is supported by the support rod 2 and extends towards the target water surface for plankton collection. The plankton net 1 is suspended in the water below the net casting track 3 by a slider 4. An electric trolley 5 is mounted on the net casting track 3, which drives the slider 4 to slide along the net casting track 3. The electric trolley 5 drives the plankton net 1 to catch plankton in the target water surface according to a set time. In this embodiment, the electric trolley 5 can be equipped with a battery. It drives the slider 4 to slide along the net casting track 3. At this time, the slider 4 drives the plankton net 1 to catch plankton in the water.

[0018] In this embodiment, the net-casting track 3 is in the shape of an "∞" shaped infinity symbol. The time taken for the electric trolley 5 to drive the slider 4 to complete one revolution along the net-casting track 3 is the required set time. This required set time is 5 minutes. The net-casting track 3 is also the movement track for the plankton net 1, used for the "∞" shaped movement of the plankton net 1. A rectangular movement module is attached to the movement track to connect the plankton net and to complete the movement function on the track. The speed of the electric trolley 5 is controlled so that when the electric trolley 5 completes one revolution in the "∞" shaped movement, it is the set time for collecting plankton. This prevents inaccurate collection time due to forgetting, thus ensuring that there is a certain time error in the quantitative sample.

[0019] In this embodiment, support rod 2 is a telescopic rod. Support rod 2 is a grippable or fixed telescopic rod used for holding or placing during use, increasing the stability of the device. A data cable is placed inside the rod to obtain power from the netting track 3; a small timer and a motion module switch are also placed there. The timer is used to set the sampling duration of the device and control the sampling time; sampling automatically stops when the time is up. The timer is powered by a built-in battery in the netting track 3. The motion module switch controls the start and stop of the motion module on the motion track. Support rod 2 also has a timer and a buzzer. The timer is connected to the buzzer, and the buzzer sounds when the timer expires.

[0020] In some other embodiments, the support rod 2 is connected to the net-casting track 3 by a connecting rod 6; the connecting rod 6 is a 1-3m long metal rod with a built-in battery; the battery supplies power to the electric trolley 5 through wires. Additionally, a plankton recovery device 7 is provided on the plankton net 1 to recover plankton.

[0021] In this embodiment, support rod 2 is a telescopic rod that can be gripped or fixed, used for gripping or placing during use to increase the stability of the device. In other embodiments, two support rods may also be used, such as... Figure 2 As shown, the two support rods 2 are connected to two symmetrical points on the "∞"-shaped net-casting track 3 via connecting rods 6. This makes the net-casting track 3 more stable, allowing the electric trolley 5 to slide more smoothly on the "∞"-shaped track 3. The plankton net 1, submerged in water, moves in an "∞" shape under the drive of the electric trolley 5. In this embodiment, the plankton net 1 is designed with a replaceable structure to easily adapt to different types of nets to meet different sampling needs. The net has metal rings that can connect with the metal rings on the upper slider 4 of the "∞"-shaped net-casting track 3. In other embodiments, a timing device can be installed on the electric trolley 5. The support rod 2 extends the "∞"-shaped net-casting track 3 towards the target water surface. When the plankton net 1 is immersed in the water, the electric trolley 5 is started. The electric trolley 5 drives the slider 4 to slide on the "∞"-shaped net-casting track 3, causing the plankton net 1 to move in an "∞" shape in the water. When the set time is up, the electric trolley 5 stops, and the "∞"-shaped net-casting track 3 carries the plankton net 1 ashore. The captured plankton is then recovered from the plankton recovery device 7 installed on the plankton net 1. The electric trolley 5 can be controlled remotely, and the start time can be set when using the remote control.

[0022] Compared to current plankton collection devices, the automated plankton collection device in this embodiment is primarily labor-saving. Previously, it required manual labor to draw an "∞" shape with a plankton net in the water for 5 minutes to concentrate and collect plankton. This process was very strenuous and tiring. Now, an electric slider replaces the manual "∞" drawing, saving considerable effort. It can also simultaneously complete the "∞" drawing and collection of plankton.
