Description

Technical Field

[0001] This utility model belongs to the field of marine engineering, and in particular relates to a seawater sampling device with a float. Background Technology

[0002] A floating seawater sampling device is a device used for marine research, environmental monitoring, or seawater sampling. Its design typically includes a float and one or more sampling containers. The float allows the entire device to float on the water surface and remain stable. The float is generally made of lightweight materials to ensure that the device can float on the water surface, while the sampling device is used to collect seawater samples from different depths.

[0003] Traditional sampling devices may allow suspended particles, plankton, sediments, and impurities to enter the sampling device when sampling seawater, resulting in impure seawater samples that affect the accuracy of subsequent analysis. Therefore, we propose a seawater sampling device with a float. Utility Model Content

[0004] The purpose of this invention is to provide a seawater sampling device with a float. A motor rotates a threaded rod, which in turn drives a threaded cylinder to move downwards. The connecting frame is then completely immersed in seawater for sampling, thus solving the problem of filtering seawater during sampling.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A seawater sampling device with a float includes a base, a support frame fixedly connected to the top of the base, a sampling mechanism on the support frame, and a stabilizing mechanism on the base.

[0007] The sampling mechanism includes a motor frame, a motor fixedly connected to the inner wall of the motor frame, a threaded rod fixedly connected to the output shaft of the motor via a coupling, a threaded cylinder threadedly connected to the outer surface of the threaded rod, a sliding groove provided inside the support frame, a limit strip slidably connected to the inner wall of the sliding groove, a connecting frame fixedly connected to the bottom of the threaded cylinder, a filter box fixedly connected to the outer surface of the connecting frame, a collection box slidably connected to the inner wall of the connecting frame, a rotating door rotatably connected to the inner wall of the connecting frame, a fixing plate fixedly connected to the outer surface of the rotating door, and bolts threadedly connected to the inner wall of the fixing plate.

[0008] Furthermore, the bottom of the motor frame is fixedly connected to the top of the support frame, the outer surface of the threaded rod is rotatably connected to the inner wall of the support frame, two sliding grooves are provided, and the side of the limiting strip that is close to each other is fixedly connected to the outer surface of the threaded cylinder.

[0009] Furthermore, the inner wall of the filter box is fixedly connected to the outer surface of the threaded cylinder, the outer surface of the fixing plate is slidably connected to the outer surface of the filter box, and the outer surface of the bolt is threadedly connected to the inner wall of the filter box.

[0010] Furthermore, the stabilizing mechanism includes two floats fixedly connected to the inner wall of the base. A connecting platform is fixedly connected to the top of the base, and a rotating plate is rotatably connected to the inner wall of the connecting platform. Several rotating plates are provided.

[0011] Furthermore, the outer surface of the rotating plate contains the same parts, a connecting block one is fixedly connected to the top of the rotating plate, a moving rod is rotatably connected to the inner wall of the connecting block one, and a connecting block two is rotatably connected to the end of the moving rod away from the connecting block one.

[0012] Furthermore, a connecting box is fixedly connected to the top of the connecting platform. Several connecting boxes are provided. The connecting boxes contain identical internal parts. A slider is slidably connected to the inner wall of the connecting box. The outer surface of the slider is fixedly connected to the outer surface of the connecting block.

[0013] Furthermore, a slider is fixedly connected to the outer surface of the slider, and two sliders are provided in total. The outer surface of the slider is slidably connected to the inner wall of the connecting box. A fixing block is fixedly connected to the outer surface of the connecting box, and a plurality of fixing blocks are provided in total. A fixing rod is fixedly connected to one side of the fixing blocks that are close to each other.

[0014] Furthermore, the outer surface of the fixing rod is slidably connected to the inner wall of the slide bar, a spring is fixedly connected to the top of the slide bar, the end of the spring away from the slide bar is fixedly connected to the outer surface of the fixing block, and the inner side of the spring is sleeved with the outer surface of the fixing rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a filter box. The motor drives the threaded rod to rotate, which in turn causes the threaded cylinder to move downwards. The threaded cylinder then moves the limiting strip within the sliding groove, which in turn moves the connecting frame downwards. This, in turn, causes the filter box to move downwards. By using a filter box capable of filtering seawater, the system achieves the effect of filtering seawater before collection, removing suspended particles, plankton, sediment, and impurities from the seawater. This ensures a purer water sample and avoids the impact of pollution sources on the accuracy of subsequent analysis.

[0017] 2. This utility model incorporates a rotating plate. When seawater hits the device, it first contacts the rotating plate, which then rotates upwards. This rotation causes connecting block one to rotate, which in turn pushes the moving rod. The moving rod then pushes connecting block two upwards, causing the connecting block two to slide within the connecting box. By using a rotating plate that can rotate within the connecting platform, the device can float more stably on the sea surface, helping to maintain a horizontal position and preventing it from tilting or overturning due to wind, waves, or currents.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please refer to Figures 1-7 In one embodiment of this utility model, a seawater sampling device with a floating body is provided, including a base 101, a support frame 102 fixedly connected to the top of the base 101, a sampling mechanism 2 provided on the support frame 102, and a stabilizing mechanism 3 provided on the base 101. When the device floats on the sea surface, the stabilizing mechanism 3 will improve the stability of the device and prevent the device from tipping over. Then the sampling mechanism 2 will filter and sample the seawater.

[0030] Furthermore, in this embodiment of the present invention, the sampling mechanism 2 includes a motor frame 201, a motor 202 is fixedly connected to the inner wall of the motor frame 201, a threaded rod 203 is fixedly connected to the output shaft of the motor 202 through a coupling, and a threaded cylinder 204 is threadedly connected to the outer surface of the threaded rod 203. The motor frame 201 fixes the motor 202 to prevent the motor 202 from rotating due to rotation, and ensures that the motor 202 can work normally to complete the sampling.

[0031] Furthermore, the support frame 102 has a sliding groove 205 inside, and a limit strip 206 is slidably connected to the inner wall of the sliding groove 205. A connecting frame 207 is fixedly connected to the bottom of the threaded cylinder 204, and a filter box 208 is fixedly connected to the outer surface of the connecting frame 207. The connecting frame 207 will drive the filter box 208 to move downward together. When the filter box 208 is immersed in seawater, the filter box 208 will filter the seawater and then enter the connecting frame 207 for sampling.

[0032] Furthermore, in this embodiment of the present invention, a collection box 209 is slidably connected to the inner wall of the connecting frame 207, and a rotating door 210 is rotatably connected to the inner wall of the connecting frame 207. A fixing plate 211 is fixedly connected to the outer surface of the rotating door 210, and a bolt 212 is threadedly connected to the inner wall of the fixing plate 211. The bolt 212 can be tightened in the filter box 208 and the fixing plate 211 to fix the rotating door 210 and prevent the collection box 209 from falling out of the device during movement.

[0033] The bottom of the motor frame 201 is fixedly connected to the top of the support frame 102, the outer surface of the threaded rod 203 is rotatably connected to the inner wall of the support frame 102, two slide grooves 205 are provided, and the side of the limiting strips 206 that are close to each other is fixedly connected to the outer surface of the threaded cylinder 204. The limiting strips 206 restrict the movement of the threaded cylinder 204 to prevent the threaded cylinder 204 from rotating during the movement, so as to ensure that the device can complete the sampling normally.

[0034] In one implementation, the inner wall of the filter box 208 is fixedly connected to the outer surface of the threaded cylinder 204, the outer surface of the fixing plate 211 is slidably connected to the outer surface of the filter box 208, the outer surface of the bolt 212 is threadedly connected to the inner wall of the filter box 208, and the threaded cylinder 204 fixes the filter box 208 to prevent the filter box 208 from shifting during sampling, thus ensuring that the filter box 208 can stably sample seawater.

[0035] Furthermore, in this embodiment of the present invention, the stabilizing mechanism 3 includes a float 301 fixedly connected to the inner wall of the base 101. Two floats 301 are provided. A connecting platform 302 is fixedly connected to the top of the base 101. A rotating plate 303 is rotatably connected to the inner wall of the connecting platform 302. The connecting platform 302 fixes the position of the rotating plate 303, so that the rotating plate 303 can only rotate within the connecting platform 302, ensuring that the device can remain stable on the sea surface.

[0036] There are several rotating plates 303. The parts contained on the outer surface of the rotating plates 303 are the same. A connecting block 304 is fixedly connected to the top of the rotating plate 303. A moving rod 305 is rotatably connected to the inner wall of the connecting block 304. When the rotating plate 303 rotates, it will drive the connecting block 304 to move. Then the connecting block 304 will drive the moving rod 305 to move, so that the device can carry out the next transmission step.

[0037] The end of the moving rod 305 away from the first connecting block 304 is rotatably connected to the second connecting block 306. The top of the connecting platform 302 is fixedly connected to the connecting box 307. There are several connecting boxes 307. The moving rod 305 will drive the second connecting block 306 to move upward, so that the second connecting block 306 can perform transmission and play a role in the stability of the device.

[0038] Furthermore, the internal components of the connecting box 307 are identical. A slider 308 is slidably connected to the inner wall of the connecting box 307. The outer surface of the slider 308 is fixedly connected to the outer surface of the connecting block 306. The connecting box 307 restricts the slider 308 so that the slider 308 will not deviate during movement, ensuring that the stabilizing mechanism 3 can function stably.

[0039] Optionally, a slider 309 is fixedly connected to the outer surface of the slider 308. Two sliders 309 are provided. The outer surface of the slider 309 is slidably connected to the inner wall of the connecting box 307. A fixing block 310 is fixedly connected to the outer surface of the connecting box 307. The slider 308 will drive the slider 309 to slide within the connecting box 307. The connecting box 307 restricts the movement of the slider 309 to prevent the slider 309 from deviating.

[0040] Furthermore, a number of fixing blocks 310 are provided. A fixing rod 311 is fixedly connected to one side of the fixing blocks 310 that is close to each other. The outer surface of the fixing rod 311 is slidably connected to the inner wall of the slide bar 309. The fixing blocks 310 fix the fixing rod 311 to prevent the fixing rod 311 from falling off the device due to movement, thus ensuring that the device can work normally.

[0041] A spring 312 is fixedly connected to the top of the slide bar 309. The end of the spring 312 away from the slide bar 309 is fixedly connected to the outer surface of the fixing block 310. The inner side of the spring 312 is sleeved with the outer surface of the fixing rod 311. The fixing rod 311 restricts the movement of the spring 312 to prevent the spring 312 from tilting or shifting during the movement, ensuring that the device can work normally and stably.

[0042] When the staff needs to use the equipment, the float 301 provides a certain buoyancy for the device, enabling it to float on the seawater. When the seawater hits the device, it will first contact the rotating plate 303, which will then rotate upward. At this time, the rotating plate 303 will drive the connecting block 1 304 to rotate, and then the connecting block 1 304 will push the moving rod 305. At this time, the moving rod 305 will push the connecting block 2 306 upward, and then the connecting block 2 306 will drive the slider 308 to slide in the connecting box 307. Then the slider 308 will drive the slide bar 309 to slide on the fixed rod 311. At the same time, the slide bar 309 will also compress the spring 312 to buffer the impact of the seawater, thus making the device float more stably on the sea surface and helping the device maintain a horizontal state, avoiding tilting or capsizing under the influence of wind, waves or currents.

[0043] Then the spring 312 will quickly rebound to reset the rotating plate 303. During sampling, the motor 202 can be started. At this time, the motor 202 will drive the threaded rod 203 to rotate. Then the rotation of the threaded rod 203 will cause the threaded cylinder 204 to move downward. At this time, the threaded cylinder 204 will drive the limit bar 206 to slide in the slide groove 205. Then the threaded cylinder 204 will drive the connecting frame 207 to move downward. At this time, the connecting frame 207 will also drive the filter box 208 to move downward. When the filter box 208 is immersed in seawater, the filter box 208 will filter the seawater.

[0044] Then the seawater enters the collection box 209 on the connecting frame 207, achieving the effect of filtering the seawater before collection. This removes suspended particles, plankton, sediment and impurities from the seawater, ensuring that the collected water sample is purer and avoiding the influence of pollution sources on the accuracy of subsequent analysis. When it is necessary to remove the seawater sample, the bolt 212 can be unscrewed from the filter box 208 and the fixing plate 211, and then the door 210 can be rotated away from the filter box 208 to open the connecting frame 207. Then the collection box 209 can be taken out to collect the sample.
