Description

Technical Field

[0001] The utility model belongs to the technical field of ocean measurement tools, and in particular relates to a plankton collector. Background Art

[0002] Plankton occupies an important position in the aquatic biological world. It is not only an important bait for fish, but its community structure and species composition are also often used to evaluate the ecological environment of water bodies. Usually, individual plankton are very small, but because they are large in number and widely distributed, special equipment is needed to collect plankton when detecting the ecological environment of water bodies. Currently, when collecting plankton, the tools used are generally simple plankton collection nets. For example, Patent 1 (CN106358584A) discloses a plankton collection net, which is composed of a hand-held rod, a ring body, and a collection net fixed on the ring body, and the plankton is collected manually; Patent 2 (CN217850194U) discloses another plankton collection net, which also includes a collection ring and a net cover fixed on the collection ring. By dragging the collection net, plankton enters the collection net through the collection ring mouth.

[0003] The aforementioned patents all require external force to control the collection net in order to collect plankton. Furthermore, due to the length of the collection net, a large amount of running water is required to completely collect the plankton on the collection net, which takes a long time and affects collection efficiency. Furthermore, when using the collection net, impurities and garbage can easily enter the net, causing poor water filtration and affecting collection quality. Utility Model Content

[0015] Compared with the prior art, the present invention has the following advantages: the collector of the present invention features a simple structure, easy manufacture, low cost, and wide applicability. By providing a float on the collection hopper, the collector can float on the water surface, making it suitable for both shallow and deep waters. By configuring the collection hopper, outlet, and extension tube, plankton can be collected by utilizing the flow of water in the collection area without external force. The extension tube also increases the pressure differential between the external water source and the collection hopper, further improving the collection efficiency of the collector. By providing a filter in the extension tube to filter the water source, the collection quality is improved while also effectively preventing impurities and debris from clogging the outlet pipe and / or collection hopper. Finally, the present invention only requires emptying the collection hopper to complete the plankton collection, significantly reducing the collection process and time. Furthermore, since the outlet is a detachable component, the time required to collect residual plankton and clean the screen is significantly reduced, further improving the efficiency of plankton collection.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] A plankton collector, such as Figure 1-2 As shown, the apparatus comprises a collecting hopper 1, a float 2, a drain outlet 3, and an outlet pipe 4. The collecting hopper 1 comprises a side surface and a bottom surface. The float 2 is provided at the upper end of the side surface of the collecting hopper 1 so that the biological collector can float on the water surface. The drain outlet 3 is provided in the middle of the side surface of the collecting hopper 1 so that water flowing into the collecting hopper 4 can be discharged from the collector. The outlet pipe 4 is provided at the bottom surface of the collecting hopper 1 and passes through the bottom surface of the collecting hopper 1, so that external water can flow into the collecting hopper 1 through the outlet pipe 4.

[0025] Specifically, the side of the collection hopper 1 is provided with a first mounting hole and a second mounting hole. The first mounting hole is provided on the side of the collection hopper 1 for mounting the drain outlet 3. The second mounting hole is provided at the upper end of the side of the collection hopper 2 for mounting the float 2. The float 2 is connected to the collection hopper 1 via threads through the second mounting hole. Preferably, at least one float 2 is provided on each side of the collection hopper 1 to ensure that the collector can float stably on the water surface.

[0026] The drain outlet 3 includes a screen frame 31 and a screen, the screen is fixed in the screen frame 31, the screen frame 31 is arranged in the first mounting hole, and is connected to the side of the collection bucket 1 through a fixing member, such as Figure 2 As shown. The size of the mesh in the screen can be set according to the size of the plankton to be collected. At the same time, in order to facilitate the collection of plankton and the cleaning of the screen, the screen frame 31 is detachably connected to the side.

[0027] The water outlet pipe 4 includes an inlet and a water outlet 41. The water outlet 41 is provided in the collecting bucket 1. The inlet passes through the bottom surface and is provided outside the collecting bucket 1 to allow external water to flow in from the inlet.

[0028] Furthermore, the collecting hopper 1 is a fan-shaped structure, which includes two straight side surfaces and one arc-shaped side surface, and the first mounting hole is provided on the arc-shaped side surface. Figure 1 As shown. Two first mounting holes are provided in the arcuate side surface, and correspondingly, two drainage holes 3 are provided in the collector, and the screen frame 31 in the drainage holes 3 is also arcuate, so that water flowing into the collection hopper 1 can flow out quickly. At the same time, the other adjacent side surface of the collection hopper 1 is set as a straight side surface to facilitate the dumping of the collected plankton and further improve the collection efficiency of the plankton.

[0029] During operation, with the help of the flow of the water source itself, the external water source flows into the water outlet pipe 4 from the inlet, then flows out through the outlet 41 and enters the collection bucket 1; then, after the plankton is filtered through the screen, it flows out through the drain port 3; at this time, the plankton is intercepted in the collection bucket 1 or on the screen; after the plankton is collected, the collector is salvaged and the collection bucket 1 is dumped so that the plankton is poured out of the collection bucket 1 from the straight side, thereby completing the collection of the plankton; finally, the drain port 3 is removed, and the plankton on the screen is further collected and cleaned for next use.

[0030] The plankton collector in this embodiment has the characteristics of simple structure, easy production and low cost due to the readily available materials required; and the collection of plankton can be completed without external force; at the same time, by designing the collecting bucket 1 as a fan-shaped structure, the plankton can be easily poured out from the right-angled side, thereby improving the collection efficiency; at the same time, the detachable drain port makes the collection and cleaning of plankton on the screen more convenient and quick.

[0031] Example 2:

[0032] The difference between this embodiment and embodiment 1 is that the plankton collector further includes an extension tube 5, such as Figure 3-6The extension tube 5 includes a threaded end 51 and a water inlet end 52, and the threaded end 51 and the water inlet end 52 are respectively provided at both ends of the extension tube 5. Figure 5 As shown. The threaded end 51 is connected to the inlet of the water inlet pipe 4. The water inlet end 52 is provided with a first water inlet 53 and a second water inlet 54, which are arranged opposite each other. Furthermore, a third water inlet 55 is provided at the bottom of the water inlet end 52 to make the collector more sensitive to water flow. The extension tube 5 is detachably connected to the water inlet pipe 4 to reduce the maintenance cost of the collector.

[0033] Furthermore, to prevent debris, garbage, and other items in the water from entering the collection hopper 1, the collector is further provided with a filter to filter the water, thereby preventing clogging of the outlet pipe 4 and reducing impurities in the collected material. The filter is disposed between the threaded end 51 and the water inlet end 52. Furthermore, the filter is disposed above the water inlet end 52 to prevent unfiltered water from flowing into the outlet pipe 4.

[0034] In addition, the collector further comprises a holder 6, through which the filter screen is fixed to the middle of the extension tube 5, as shown in FIG. Figure 3 and Figure 6 The fixing device 6 comprises a buckle 61 and a fastener 60. The two buckles 61 are sleeved on the buckle 61 on the extension tube 5 by the fastener 60 to connect them, and the fixing device 6 is clamped on the extension tube 5.

[0035] Specifically, the retaining ring 61 includes a ring body 62 and a connecting block 63. The connecting blocks 63 are provided at both ends of the ring body 62 and have fixing holes 64 therein. The fastener 60 passes through the fixing holes 64 on the two retaining rings 61, then connects the two retaining rings 61 and secures the holder 6 to the extension tube 5. The fastener 60 can be a bolt and a nut, and the retaining ring 61 is preferably integrally formed.

[0036] In this technical solution, a filter is added to filter the external water source to prevent impurities from entering the collection bucket 4; and an extension pipe 5 is provided to provide installation space for the filter and to increase the water pressure difference between the water inlet and the water outlet 41, making it easier for the external water source to flow into the collection bucket 1.

[0037] During assembly, first connect the threaded end of the extension tube 5 to the water inlet pipe 4. Then, install a filter screen above the water inlet end 52. Next, snap two retaining rings 61 onto the extension tube 5 and secure the filter screen with fasteners 60, completing the assembly of the collector. During operation, external water flows into the extension tube 5 through the first and second water inlets 53, 54. The filter screen located above the water inlet end 52 filters the incoming water before flowing into the water inlet pipe 4.

[0038] Example 3:

[0039] When the surface of the external water source is relatively calm, the external water source cannot flow smoothly from the water inlet end 52 into the water inlet pipe 4 and the collecting bucket 1. Therefore, the difference between this embodiment and embodiment 1 or 2 is that, Figure 3-5 As shown, an air pipe 7 is further provided in the extension pipe 5 , and the air pipe 7 is provided above the fixer 6 ; and the air pipe 7 is communicated with the extension pipe 5 .

[0040] When the external water source is relatively calm, the external air source is connected to the air pipe 7. By intermittently injecting air into the air pipe 7, the water flow in the extension pipe 5 fluctuates, and then the external water source can flow smoothly from the water inlet pipe 4 into the collection bucket 1, thereby completing the collection of plankton in the external water source.

[0041] It should be noted that the technical features in the above-mentioned embodiments 1 to 3 can be combined in any way, and the technical solutions formed by the combination all fall within the scope of protection of this application.
