Description
Technical Field
[0001] The utility model relates to a large-volume ocean water sampler, which is applied to the technical field of seabed sampling. Background Art
[0002] In recent years, with the continuous expansion of business areas, the monitoring center has developed monitoring and evaluation technology as the basis, monitoring business as the core, and meeting the national marine environmental management needs as the orientation, forming the ability to comprehensively monitor marine ecology, sea area use, and environment. The various monitoring products compiled by the monitoring center provide strong technical support for the formulation of national or regional marine economic development plans, marine functional zoning, key sea area environmental protection plans, the proposal of marine environmental disaster mitigation measures, and the decision-making of global climate change actions. Traditional marine environmental monitoring requires the water sampler to be carried deep into the seabed through a cable for sampling. The defects of this sampling method are:
[0003] (1) Existing ocean water samplers have limited storage capacity, and often the amount of samples collected at one time is insufficient, which may result in a small number of data sets, resulting in large errors, or the equipment needs to be deployed again for collection, resulting in increased costs and low efficiency.
[0004] (2) It is difficult for existing ocean water samplers to collect seawater from the seabed because when the water sampler sinks to the seabed, the seawater on the seabed becomes turbid, making it difficult to collect pure seawater.
[0005] Therefore, in order to facilitate the sampling of the near-bottom seawater, the utility model designs a large-volume ocean water sampler to address one or more of the above problems. Utility Model Content
[0006] The utility model provides a large-volume ocean water sampler, which can effectively solve the above problems.
[0007] The utility model is achieved in this way:
[0008] A large-volume ocean water sampler, comprising:
[0009] A float mechanism, comprising a plurality of floats connected in sequence;
[0010] The sampling mechanism is arranged below the float mechanism, and comprises a large-volume sampling barrel body, water inlets are arranged at both ends of the sampling barrel body, a sealing assembly for blocking the water inlet is arranged in the sampling barrel body, and a limit assembly for limiting the movement of the sealing assembly is arranged in the sealing assembly;
[0011] A release mechanism is arranged below the sampling mechanism, comprising a releaser and a counterweight block arranged below the releaser and connected to the releaser, the releaser is communicatively connected to the control unit, and a displacement sensor is arranged on the releaser;
[0012] When the release mechanism sinks to the bottom and the displacement sensor detects that the position of the releaser is no longer moving, the sealing assembly seals the water inlet to complete the water sample collection. The control unit controls the releaser to release the counterweight block, and the float device drives the sampling mechanism to float to achieve the recovery of the sampling barrel.
[0013] As a further improvement, the sealing assembly includes a fixed bracket arranged on the inner wall of the sampling barrel body, the fixed bracket is equidistant from the water inlets at both ends, the fixed bracket is provided with mounting columns symmetrically centered at both ends along the axial direction of the sampling barrel body, the upper end surface of the mounting column is provided with a first accommodating hole, the lower end surface of the mounting column is provided with a second accommodating hole, the first accommodating hole contains a first sliding rod, the first sliding rod is connected to the bottom of the first accommodating hole through a first spring, the second accommodating hole contains a second sliding rod, the second sliding rod is connected to the bottom of the second accommodating hole through a second spring, and the first sliding rod and the second sliding rod are connected to the sealing plate at one end away from the fixed bracket.
[0014] As a further improvement, the limit assembly includes a sliding groove arranged on the lower surface of the fixed bracket and symmetrical with the axis of the sampling barrel body as the center, the sliding groove passes through the mounting post and is connected to the first accommodating hole, and a slidable locking block is arranged in the sliding groove, and the locking block is connected to the sliding groove away from the mounting post through a third spring, and the locking block extends upwardly near the end of the mounting post and is provided with a first convex edge, and the first sliding rod is provided with a through hole connected to the sliding groove near one end of the fixed bracket and the first sliding rod is provided at the through hole, and the release buckle is communicatively connected with the displacement sensor, the locking block passes through the through hole away from the third spring and makes the first convex edge abut against the release buckle, the second sliding rod is a solid structure, the second sliding rod is connected to the release rod near one end of the fixed bracket, and the release rod is provided with a second convex edge at one end away from the second sliding rod, when the first convex edge abuts against the release buckle, the second convex edge abuts against the lower end surface of the locking block to fix the cover assembly.
[0015] As a further improvement, the sampling mechanism further includes an annular slot cover plate arranged at both axial ends of the sampling barrel body, one end of the annular slot cover plate is provided with a plurality of fixed slots along its axis, the sampling barrel body includes a multi-layer pressure-resistant shell, the pressure-resistant shell is arranged in the fixed slot, the other end of the annular slot cover plate is provided with a fixed cover plate rotatably connected to the slot cover plate, the fixed cover plate is provided with a first magnetic attraction portion, a limiting baffle plate is provided on one side of the annular slot cover plate, a second magnetic attraction portion is provided on the limiting baffle plate, and the first magnetic attraction portion and the second magnetic attraction portion are magnetically fixed.
[0016] As a further improvement, the outer side wall of the outermost pressure-resistant shell is axially provided with symmetrical support columns, and a depth sensing module is arranged in the middle of the support columns.
[0017] The beneficial effects of the utility model are:
[0018] (1) The sampling barrel of the utility model is large enough and can be selected according to actual usage, so as to facilitate the collection of large-volume samples for testing at one time, prevent the small size of the sampling device and the insufficient amount of collected samples, resulting in large experimental errors, or prevent the need for re-sampling, thereby reducing costs and improving efficiency.
[0019] (2) The release mechanism of the utility model sinks to the bottom. When the displacement sensor detects that the position of the releaser is no longer moving, the sealing assembly seals the water inlet to complete the water sample collection. The sealing assembly can be quickly sealed to collect pure water samples, which is convenient for obtaining accurate water sample information. The control unit controls the releaser to release the counterweight block, and the float device drives the sampling mechanism to float up to realize the recovery of the sampling barrel, which solves the problem of length limitation and difficulty in recovery when traditional sampling is recovered by using cables.
[0020] (3) The working principle of the limit assembly of the utility model is as follows: when the release mechanism sinks to the bottom and the displacement sensor detects that the position of the releaser is no longer moving, the release buckle communicated with the displacement sensor is released, so that the locking block is reset under the action of the third spring, so that the two sliding rods move downward under the elastic force of the second spring, thereby blocking the water inlet below the sampling barrel body; when the locking block is reset, the second convex edge on the release rod is disengaged from the limiting effect of the lower end surface of the locking block, so that the first sliding rod moves upward under the elastic force of the first spring, and the sealing plate installed on the first sliding rod blocks the water inlet above the sampling barrel body; because when the counterweight block sinks to the bottom, the seawater below first gradually becomes turbid upward, the limit assembly can block the water inlet below first, thereby preventing the dirty seawater from entering the sampling barrel body; therefore, the utility model can collect clean seawater, improve the purity of the sample, and improve the accuracy of the experiment.
