Description

Technical Field

[0001] This utility model relates to the field of biological collection device technology, and more specifically, to a planktonic collection structure that is easy to rinse. Background Technology

[0002] Plankton are small in size and numerous in water. They not only serve as food for fish, but their abundance also indicates the level of aquatic productivity and can be used to assess the current state of the aquatic ecosystem. Therefore, it is necessary to regularly collect plankton from water for ecological surveys.

[0003] Currently, plankton collection is primarily conducted using plankton collection nets. These nets consist of a conical mesh and a collection bottle. The collection bottle is located at the smaller diameter end of the conical mesh and is connected to the inside of the mesh. During collection, the conical mesh and collection bottle are placed in the corresponding water area. The collection bottle causes the conical mesh to sink below the surface. After a period of time, the plankton adhere to the inner wall of the conical mesh.

[0004] After collection, staff will retrieve the plankton collection net and then use a water hose to rinse the inner wall of the cone-shaped net. This serves two purposes: firstly, it causes the plankton adhering to the inner wall of the net to fall into the collection bottle for easy removal; secondly, it ensures the cleanliness of the net and prevents cross-contamination during subsequent use. However, since there is usually only one water hose for rinsing, staff need to constantly rotate the net to rinse in all directions, which is inconvenient and reduces rinsing efficiency. Utility Model Content

[0005] To address at least one of the aforementioned problems, this utility model provides a plankton collection structure that facilitates rinsing, comprising a collection net, a collection bottle, and a rinsing assembly. The collection net is cylindrical with openings at both its top and bottom ends. The collection bottle is connected to the bottom of the collection net to collect plankton inside the net. A support ring is provided at the top of the collection net. The rinsing assembly includes an annular pipe and multiple rinsing nozzles. The annular pipe is plugged into the support ring and has an inlet pipe connected to a water source. The multiple rinsing nozzles are connected to and communicate with the annular pipe, and are arranged circumferentially around the annular pipe to facilitate multi-directional rinsing of the collection net.

[0006] Optionally, the collecting net is conical, and the collecting bottle is located at the end of the collecting net with the smaller inner diameter.

[0007] Optionally, the collection bottle is made of metal.

[0008] Optionally, the flushing nozzle has a water outlet, which is flat and extends in the circumferential direction of the collection net.

[0009] Optionally, the support ring includes a support ring plate, an outer ring plate, and a blocking arc plate. The outer ring plate and the blocking arc plate are both located on top of the support ring plate and are arranged at intervals. Multiple blocking arc plates are arranged at intervals around the support ring plate. The annular pipe is located on the support ring plate and between the outer ring plate and the blocking arc plate.

[0010] Optionally, the annular pipe includes multiple arc-shaped pipes and multiple four-way connectors. Two adjacent arc-shaped pipes are connected by one of the four-way connectors. The number of four-way connectors is the same as the number of flushing nozzles and corresponds one-to-one. The flushing nozzles are located inside the collection network and are connected to and communicate with the four-way connectors. A rubber plug is inserted into one opening of the four-way connector that is not connected to the arc-shaped pipes or the flushing nozzles.

[0011] Optionally, the end of the four-way connector away from the flush nozzle passes through the outer ring plate and is suspended outside the outer ring plate.

[0012] Optionally, the flushing assembly further includes a bellows, one end of which is connected to the four-way connector and the other end of which is connected to the flushing nozzle.

[0013] Optionally, the corrugated pipe is sleeved on the four-way connector, and the corrugated pipe is provided with a cable tie, and the corrugated pipe is fixedly connected to the four-way connector through the cable tie.

[0014] Optionally, the four-way connector has an annular groove, and a rubber sealing ring is fitted inside the annular groove. The rubber sealing ring is interference-fitted into the corrugated pipe, and the cable tie is located at the rubber sealing ring.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] 1. After the collection net is retrieved from the water, the ring pipe is placed directly onto the support ring, and then the water inlet pipe is connected to the water source. Water can be sprayed out through multiple flushing nozzles to flush the collection net from multiple directions at once, which improves the convenience of rinsing the collection net.

[0017] 2. The water outlet of the flushing nozzle is designed to be flat, which increases the flushing range after the water comes out, thus improving the flushing efficiency.

[0018] 3. With the four-way connector, users can remove the rubber plug and install a flushing nozzle as needed to flush the outer wall of the collection net, thereby removing impurities and sediments adhering to the outer wall of the collection net.

[0019] 4. The corrugated pipe design allows for arbitrary adjustment of the orientation and extension length of the flushing nozzle, and keeps the adjusted nozzle in its adjusted state without the need for manual support, further improving the convenience of rinsing. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0026] This utility model provides a plankton collection structure that is easy to rinse. Example 1, see reference. Figure 1 The plankton collection structure, designed for easy rinsing, includes a collection net 1, a collection bottle 11, and a rinsing assembly 2. The collection net 1 is cylindrical, with openings at both the top and bottom. The collection bottle 11 is attached to the bottom of the collection net 1 to facilitate the collection of plankton inside. The rinsing assembly 2 is located on top of the collection net 1 and is detachably connected to it. After the collection net 1 is retrieved from the water, the rinsing assembly 2 can be placed on top of it and connected to a water source. The rinsing assembly 2 allows for multi-directional rinsing of the collection net 1, improving the convenience and efficiency of rinsing.

[0027] In this embodiment, the collection net 1 is preferably conical, with the smaller inner diameter end of the collection net 1 facing downwards. The collection bottle 11 is located at the smaller inner diameter end of the collection net 1. The collection net 1 is connected to the collection bottle 11 by a rope or strap, and the collection bottle 11 is in communication with the inside of the collection net 1, allowing plankton inside the collection net 1 to enter the collection bottle 11. The bottom of the collection bottle 11 is threaded with a screw cap; opening the screw cap allows the plankton inside the collection bottle 11 to be poured out for easy detection.

[0028] In this embodiment, the collection bottle 11 is preferably made of metal, so that the collection bottle 11 can be used as a counterweight, and there is no need to set an additional counterweight at the bottom of the collection net 1 so that the collection net 1 can sink below the water surface.

[0029] Reference Figure 1 and Figure 2 The collection net 1 has a support ring 12 connected to its top, which keeps the top opening of the collection net 1 open to allow plankton to enter. The support ring 12 includes a support ring plate 13, an outer ring plate 14, and a blocking arc plate 15, all of which are integrally formed. The support ring plate 13 has a through hole 131 at its top, which penetrates the support ring plate 13. At least two through holes 131 are provided radially along the support ring plate 13, and multiple through holes 131 are spaced apart circumferentially along the support ring plate 13. Thus, the collection net 1 can be fixedly connected to the support ring 12 by sewing thread through and wrapping around the through holes 131. The outer ring plate 14 and the blocking arc plate 15 are both located on top of the support ring plate 13 and are arranged at intervals radially along the support ring plate 13. The blocking arc plate 15 is located on the inner wall of the support ring plate 13, and multiple blocking arc plates 15 are spaced apart circumferentially along the support ring plate 13. The rinsing assembly 2 is placed on the support ring plate 13 and is located between the outer ring plate 14 and the blocking arc plate 15, which not only limits the placement of the rinsing assembly 2, but also makes the placement and removal of the rinsing assembly 2 more convenient and quick.

[0030] Combination Figure 1 Reference Figure 2 and Figure 3The flushing assembly 2 includes an annular pipe 21, flushing nozzles 22, and corrugated pipes 23. The annular pipe 21 is placed on the supporting ring plate 13 and is located between the outer ring plate 14 and the blocking arc plate 15. Multiple flushing nozzles 22 and corrugated pipes 23 are provided, with the number of flushing nozzles 22 and corrugated pipes 23 being the same and corresponding one-to-one. Multiple flushing nozzles 22 are arranged circumferentially at intervals on the annular pipe 21. One end of the corrugated pipe 23 is connected to the annular pipe 21; the other end is connected to the flushing nozzle 22. The corrugated pipe 23 can maintain its deformed or extended state after deformation or extension, thus allowing arbitrary adjustment of the orientation and extension length of the flushing nozzle 22 to achieve flushing at different positions; and maintaining the adjusted flushing nozzle 22 in its adjusted state without the need for manual support, improving the convenience of flushing. Furthermore, the length specification of the corrugated pipe 23 can be replaced, allowing for the replacement of corrugated pipes 23 with corresponding specifications for collection nets 1 of different lengths or diameters.

[0031] Combination Figure 1 Reference Figure 2 and Figure 3 The annular pipe 21 includes multiple arc-shaped pipes 24 and multiple four-way connectors 25. Two adjacent arc-shaped pipes 24 are connected by a four-way connector 25. The number of four-way connectors 25 is the same as the number of corrugated pipes 23 and they correspond one-to-one.

[0032] A tee connector 26 connects the two arc-shaped pipes 24. A water inlet pipe 27 is installed at the interface of the tee connector 26 that is not connected to the two arc-shaped pipes 24. The water inlet pipe 27 can be connected to the water source through a soft water pipe, so that water can enter the annular pipe 21.

[0033] Combination Figure 1 Reference Figure 2 and Figure 3 Two opposing interfaces of the four-way connector 25 are arranged radially along the collecting mesh 1; the other two opposing interfaces are arranged circumferentially along the collecting mesh 1 to facilitate welding connection with the arc-shaped pipe 24. The interface end of the four-way connector 25 closest to the center of the collecting mesh 1 is located between two adjacent blocking arc plates 15 and protrudes from the support ring plate 13 in a cantilevered state to facilitate connection with the bellows 23, while also placing the flushing nozzle 22 inside the collecting mesh 1. The outer ring plate 14 has multiple notches, the number of which is the same as the number of four-way connectors 25 and corresponds one-to-one. The end of the four-way connector 25 furthest from the blocking arc plate 15 is inserted into the notch and cantilevered outside the outer ring plate 14.

[0034] Since the four-way connector 25 has three interfaces that connect to two arc-shaped pipes 24 and one corrugated pipe 23 respectively, a rubber plug 251 is interference-fitted into the fourth interface of the four-way connector 25 (the interface of the four-way connector 25 that passes through the notch of the outer ring plate 14). The user can remove the rubber plug 251 and install the corrugated pipe 23 and the flushing nozzle 22 as needed to flush the outer peripheral wall of the collection net 1.

[0035] Combination Figure 1 Reference Figure 2 and Figure 3 One end of the bellows 23 is fitted onto the four-way connector 25; the other end is fitted onto the flushing nozzle 22. The four-way connector 25 has an annular groove, within which a rubber sealing ring 252 is fitted, interference-fitted into the bellows 23. A cable tie is attached to the bellows 23, securing it to the four-way connector 25. The cable tie is located at the rubber sealing ring 252. When the cable tie is tightened, it constricts the rubber sealing ring 252, causing it to deform and improving the seal at the connection between the bellows 23 and the four-way connector 25, preventing water leakage. Furthermore, in outdoor operations where tools like wrenches or wires are inconvenient to carry, even if the bellows 23 becomes loose, it can be easily and cost-effectively re-secured with the cable tie. Correspondingly, the flushing nozzle 22 is also connected to the bellows 23 via another cable tie.

[0036] The flushing nozzle 22 is equipped with a water outlet, which is flat and extends in the circumferential direction of the collection net 1 and is larger than the inner diameter of the corrugated pipe 23. This increases the flushing range after water is discharged, thereby improving the flushing efficiency.

[0037] The implementation principle of the plankton collection structure for easy rinsing in this application embodiment is as follows: When collecting plankton, the collection structure is placed on a boat and then sailed to a designated water area. After the plankton collection is completed, the collection net 1 is hoisted by the hoisting device on the boat and located outside the hull. The support ring 12 keeps the top opening of the collection net 1 in a supported state to facilitate the entry of plankton into the collection net 1. After the collection net 1 is hoisted from below the water surface, the annular pipe 21 can be directly placed on the support ring plate 13, and the annular pipe 21 is limited between the outer ring plate 14 and the blocking arc plate 15. Then, the water inlet pipe 27 is connected to the water source carried on the boat to inject water into the annular pipe 21. The water in the annular pipe 21 will flow out from the outlet of multiple flushing nozzles 22 to achieve multi-directional rinsing of the collection net 1. Because the plankton is particularly small, the mesh of the collection net 1 is also relatively small. During rinsing, some water can flow along the inner wall of the collection net 1. After rinsing the collection net 1, simply remove the rinsing component 2 from the support ring 12.

[0038] Furthermore, the corrugated pipe 23 allows for arbitrary adjustment of the orientation and extension length of the flushing nozzle 22, ensuring that the adjusted nozzle 22 remains in its adjusted state without requiring manual support. The length of the corrugated pipe 23 can be adjusted according to the length of the collection net 1 to ensure that when the corrugated pipe 23 is fully extended, the water flowing from the flushing nozzle 22 can flow to the side of the collection net 1 closest to the collection bottle 11, thereby...

[0039] With the four-way connector 25 in place, the user can remove the rubber plug 251 and install the corrugated pipe 23 and the flushing nozzle 22 as needed, thereby flushing the outer wall of the collection net 1.

[0040] Reference Figure 4 Example 2 differs from Example 1 in that: after the collection net 1 is retrieved from underwater, a conical plastic shell 3 is fitted onto it, with the larger diameter end of the shell 3 facing upwards. Two symmetrically spaced through holes are formed on the outer wall of the top of the plastic shell 3, and a connecting rope 31 is threaded through each hole. Correspondingly, two hooks 32 are welded to the outer wall of the outer ring plate 14, each hook corresponding to one of the two connecting ropes 31. The connecting ropes 31 are hung on the hooks 32, thus allowing the plastic shell 3 to hang on the support ring 12. The inner diameter of the bottom of the plastic shell 3 is larger than the outer diameter of the collection bottle 11, allowing the collection bottle 11 to pass through smoothly during installation. The conical plastic shell 3 allows more water to flow to the bottom of the collection net 1 during flushing, conserving water and improving the flushing effect.
