Description

Technical Field

[0001] The utility model relates to the technical field of collection devices, in particular to a buoy-type plankton collection device. Background Art

[0002] Plankton is an important part of the marine ecosystem. The research on its species, quantity, distribution, etc. is the basis of disciplines such as marine biology and ecology. When conducting research, scientific researchers need to use collection devices to collect plankton and provide a large number of biological samples for it.

[0003] When the existing collection devices are in use, the net bags used for collecting plankton are mostly fixed structures. When it is necessary to replace net bags with different mesh numbers or clean the net bags, they cannot be quickly disassembled, and it is also not easy to take out the collected samples, which increases the operation complexity of the staff and results in poor flexibility in use.

[0004] Therefore, it is urgently necessary to set up a structure that can quickly disassemble the collection net bag, so that it can replace net bags with different mesh numbers as needed or can be quickly disassembled for cleaning when the net bag is blocked, reducing the operation difficulty and solving the problem that most collection devices are fixed structures and are not convenient for quick disassembly. Summary of the Utility Model

[0005] In order to overcome the problem that when the collection device is in use, the net bags used for collecting plankton are mostly fixed structures, when it is necessary to replace net bags with different mesh numbers or clean the net bags, they cannot be quickly disassembled, and it is also not easy to take out the collected samples, which increases the operation complexity of the staff and results in poor flexibility in use.

[0006] The technical solution of the utility model is as follows: a buoy-type plankton collection device, including a buoy floating bottom plate; further including a floating airbag, a support suspension, a collection depth adjustment component, an installation ring plate, a counterweight ball and a quick-disassembly net bag collection component; a floating airbag is installed at the side end of the buoy floating bottom plate; a support suspension is fixedly connected to the upper end of the buoy floating bottom plate; a collection depth adjustment component is installed at the lower end of the support suspension; an installation ring plate is arranged below the buoy floating bottom plate; a counterweight ball is installed at the side end of the installation ring plate; a quick-disassembly net bag collection component is arranged inside the installation ring plate; the quick-disassembly net bag collection component includes an insertion cylinder, a clamping insertion block and a net bag fixing ring plate; the insertion cylinder is fixedly connected to the inner side end of the installation ring plate; the clamping insertion block is slidably connected inside the insertion cylinder; the upper end of the clamping insertion block is fixedly connected to the net bag fixing ring plate.

[0007] Preferably, during the use of the acquisition device, the net fixing ring plate in the quick-release net collection assembly is quickly fixed in the insertion cylinder inside the installation ring plate through the clamping insertion block below, and is reinforced by the fixing screw, so that the collection net body below the net fixing ring plate can be quickly fixed inside the installation ring plate, and can be disassembled when it is necessary to replace nets of other meshes or clean the sundries in the net. The collection sleeve can be quickly detached from the collection net body. At the same time, the elastic anti-backflow plate inside the collection sleeve can be opened under the impact of water flow when the collection net body is lifted upward, so that the plankton in the collection net body can enter the collection sleeve. When it is about to emerge from the water surface, due to the slower water flow, the elastic anti-backflow plate clings to the lower part of the feed through plate, and at this time, the collected plankton can be prevented from falling back into the water again. The motor in the collection depth adjustment assembly can drive the wire winding roller to rotate, so as to control the release length of the first pull rope according to the collection requirements at different water depth positions. At the same time, the tension spring below the first pull rope can reduce the initial traction force in the lifting installation ring plate, avoiding the first pull rope from breaking due to excessive tension caused by sudden traction. The second pull rope and the pivot plate can enable the installation ring plate to be stably lifted out of the water.

[0008] Preferably, the quick-release net collection assembly further includes a fixing screw, a shielding wire mesh, a collection net body, a threaded groove insertion block, a collection sleeve, a discharge pipe, a valve, a feed through plate and an elastic anti-backflow plate; the fixing screw is internally threaded in the insertion cylinder and the clamping insertion block; a shielding wire mesh is installed at the upper end of the net fixing ring plate; a collection net body is installed at the lower end of the net fixing ring plate.

[0009] Preferably, a threaded groove insertion block is installed at the lower end of the collection net body; the outer end of the threaded groove insertion block is threadedly connected to the collection sleeve; the lower end of the collection sleeve is fixedly connected to the discharge pipe.

[0010] Preferably, a valve is arranged at the outer end of the discharge pipe; a feed through plate is arranged inside the collection sleeve; an elastic anti-backflow plate is arranged at the lower end of the feed through plate.

[0011] Preferably, the collection depth adjustment assembly includes a top extension block, a motor, a wire winding roller, a first pull rope, a tension spring, a pivot plate and a second pull rope; the top extension block is fixedly connected to the top end of the support suspension; a motor is installed at the side end of the top extension block; the output shaft of the motor passes through the top extension block and is fixedly connected to the central shaft of the wire winding roller.

[0012] Preferably, the first pull rope is slidably connected to the outer end of the wire winding roller; the lower end of the first pull rope is fixedly connected to the tension spring.

[0013] Preferably, the lower end of the tension spring is fixedly connected to the pivot plate; the side end of the pivot plate is hinged to the second pull rope; the lower end of the second pull rope is hinged to the upper end of the installation ring plate.

[0014] Advantages of the utility model:

[0015] During the use of the collection device, the mesh bag fixing ring plate is quickly fixed in the insertion cylinder inside the installation ring plate through the clamping insertion block below, and is reinforced by the fixing screw, so that the collection mesh bag body below the mesh bag fixing ring plate can be quickly fixed inside the installation ring plate, and can be disassembled when it is necessary to replace the mesh bag with other mesh numbers or clean the sundries in the mesh bag. The shielding wire mesh can block the relatively large sundries in the water from mixing into the inside of the collection mesh bag body. The collection sleeve can be quickly detached from the collection mesh bag body. At the same time, the elastic anti-backflow plate inside the collection sleeve can be opened under the impact of the water flow when the collection mesh bag body is lifted upward, so that the plankton in the collection mesh bag body can enter the collection sleeve. When it is about to emerge from the water surface, due to the slow water flow, the elastic anti-backflow plate clings to the lower part of the feed through plate, and at this time, it can prevent the collected plankton from falling back into the water again.
