Description

Technical Field

[0001] This invention relates to the field of multi-channel water sampler technology, specifically a seawater sampling device for marine forecasting services. Background Technology

[0002] Multichannel water samplers are the core equipment for marine stratified water sampling. They can simultaneously collect seawater samples from multiple depths at one time. They are widely used in seawater sampling for marine forecasting services, providing raw samples for monitoring key parameters such as seawater quality, temperature, and salinity. They are important equipment to ensure the accuracy and reliability of marine environmental observation and forecasting data.

[0003] Chinese patent application CN117848771A discloses a multi-channel water sampler and sampling method. The device uses a drive mechanism to tighten the upper and lower caps of the sampling bottle via a connecting rope. When the device is retrieved, the drive mechanism will loosen the connecting rope, so that the upper and lower caps are tightly sealed at the water inlet by rubber bands, thus preventing seawater from being exposed.

[0004] Multi-channel water samplers rely on solenoid valves to control the opening and closing of the sampling bottle caps. When the device is lowered to a preset depth, the electromagnetic trigger unlocks the cap, allowing for stratified water sample collection at different depths. However, marine conditions are complex and variable, often resulting in electromagnetic malfunctions that cause the sampling bottles to close prematurely before reaching the designated depth. This leads to sample collection failures and distorted stratification data, severely impacting the accuracy of marine monitoring and scientific research data. Therefore, we propose a seawater sampling device for marine forecasting services. Summary of the Invention

[0005] The purpose of this invention is to provide a seawater sampling device for marine forecasting services to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A seawater sampling device for marine forecasting services includes a mounting frame. Several water sampling bottles are fixedly connected to the surface of the mounting frame. Each water sampling bottle has two sealing caps inside, located at the upper and lower ends of the bottle respectively. A traction rope is fixedly connected to the surface of both sealing caps. A collar is fixedly connected to the surface of the upper sealing cap. Two mounting plates are fixedly connected to the inner wall of each water sampling bottle. An elastic band connects each mounting plate to its corresponding sealing cap. An electromagnetic release body is fixedly connected to the inner wall of the mounting frame. The collar is fitted onto the outside of the electromagnetic release body when the sealing cap is in the open state. The mounting frame is equipped with an anti-mis-closing mechanism to ensure accurate water sampling depth and improve sampling reliability. The anti-misclosing mechanism includes several mounting frames, several ropes, several airbags, several guide blocks, several transmission plates, several spring return shafts, several limit plates, and several irregular shafts. Each rope consists of two sections of rope with different diameters, and the junction of the two sections is covered with sheet metal.

[0007] Preferably, each rope is located inside the mounting frame, with its top end passing through the mounting frame and the guide block and extending above the guide block. The top end of the rope is fixedly connected to the bottom surface of the airbag. Each guide block has a through hole on its surface, the diameter of which is larger than the small diameter section of the rope and smaller than the large diameter section of the rope. Each guide block is located on one side of the transmission plate. Each spring return shaft is rotatably connected to the inner wall of the transmission plate. Each limiting plate is fixedly connected to the surface of the spring return shaft. The surface of each limiting plate abuts against the surface of the irregular shaft. The irregular shaft can rotate as the sealing cover is opened.

[0008] Preferably, the surface of each mounting frame is fixedly connected to the surface of the water collection bottle, and the surface of each water collection bottle is fixedly connected to two fixing blocks, which are located at the upper and lower ends of the water collection bottle, respectively. The inner wall of each fixing block is rotatably connected to a drive shaft, and one end of the upper drive shaft passes through the mounting frame and is rotatably connected to the inner wall of the mounting frame. The inner wall of each irregular shaft is fixedly connected to the surface of the upper drive shaft, and the surface of each sealing cap is fixedly connected to two connecting plates, and the surface of each connecting plate is fixedly connected to the surface of the drive shaft.

[0009] Preferably, each mounting frame has a rotating shaft rotatably connected to its inner wall, two partitions are fixedly connected to the surface of each rotating shaft, the surface of each rope is wound around the surface of the rotating shaft, a drive motor is fixedly connected to the inner wall of each mounting frame, and the output end of each drive motor is fixedly connected to one end of the rotating shaft.

[0010] Preferably, each mounting frame has two sets of positioning blocks fixedly connected to its inner wall, with two positioning blocks in each set. The inner walls of each pair of positioning blocks are rotatably connected to a positioning shaft. The surface of each positioning shaft is covered with a rubber layer. Each rope passes between the two sets of positioning shafts. Each mounting frame has two first limiting shafts fixedly connected to its inner wall. Each guide block is slidably connected to the surfaces of the two first limiting shafts. Each first limiting shaft consists of two columns of different diameters, with the lower column having a larger diameter to provide support for the guide block.

[0011] Preferably, each of the transmission plates has a roller rotatably connected to its inner wall, and the surface of each roller is in contact with the inclined surface of the guide block. Each of the mounting frames has two sets of second limiting shafts and two sets of force springs fixedly connected to its inner wall. Each set of second limiting shafts and force springs consists of two shafts. Each second limiting shaft is located in the inner cavity of the force spring. Each transmission plate is slidably connected to the surface of the two sets of second limiting shafts. Each of the mounting frames has a lip-shaped sliding seal fixedly connected to its inner wall. One end of each rope passes through the lip-shaped sliding seal and extends above it. The mounting frame is equipped with a rope anti-sway limiting mechanism.

[0012] Preferably, the rope anti-sway limiting mechanism includes several fixed rings and several swing rings. The bottom end of each fixed ring is fixedly connected to the upper surface of the mounting frame. Several positioning springs are fixedly connected to the inner ring of each fixed ring and the inner wall of the swing ring. One end of each rope passes through the swing ring and extends above the swing ring. The inner ring of each fixed ring, the inner ring of the swing ring, and the outer ring of each swing ring are covered with a rubber layer.

[0013] Preferably, the rope does not contact the inner ring of the swing ring when it is in a normal vertical state, but abuts against the inner ring of the swing ring when the rope is tilted, and a warning mechanism is provided inside the mounting frame.

[0014] Preferably, the warning mechanism includes several return springs, several push-button timers, several extrusion shafts, and several force-bearing plates. Each mounting frame has a side mounting cavity inside one side wall. Each return spring and push-button timer is disposed in the side mounting cavity. The top ends of every two return springs are fixedly connected to the inner wall of the mounting frame. The surface of each limiting plate is in contact with the inner wall of the force-bearing plate and cannot rotate significantly around the axis of the spring return shaft. The bottom end of each extrusion shaft is fixedly connected to the upper surface of the force-bearing plate. Each push-button timer has a push-button switch on its bottom surface. The top end of each extrusion shaft is in contact with the bottom end of the push-button switch.

[0015] Preferably, each of the push-button timers has two reset switches on its bottom surface, and two rubber sleeves are fixedly connected to the inner wall of the mounting frame. One end of each rubber sleeve is located below the corresponding reset switch. A transparent glass is fixedly connected to the inner wall of each mounting frame, and each transparent glass corresponds to the display screen of the push-button timer.

[0016] The beneficial effects are: 1. This invention allows the length of the small-diameter section of the rope to be set in advance according to the preset sampling depth of the water sampling bottle; the sealing cover is opened in advance so that the collar is fitted onto the electromagnetic release body. When the sealing cover is opened, the transmission shaft drives the irregular shaft to rotate, so that the limiting plate is in a limited state, thereby locking the closing action of the sealing cover. During the lowering of the equipment, the rope can pass smoothly through the guide block; when the water sampling bottle reaches the specified sampling depth, the large-diameter section of the rope and the guide block cooperate to trigger the mechanism to release the limiting constraint of the limiting plate, and the sealing cover can close normally.

[0017] 2. In this invention, the swing ring and the positioning spring are configured in conjunction. The positioning spring is fixedly connected to the fixed ring, providing installation support for the swing ring. When the water flow is large enough that the rope cannot remain vertical, the rope will tilt inside the swing ring and come into contact with the rubber layer of the inner ring of the swing ring. The friction between the rubber layer and the rope slows down the continuous upward movement of the rope, keeping the rope taut. The greater the water flow intensity, the larger the contact area between the rope and the swing ring, and the greater the friction between them, effectively avoiding the problem of the limit plate prematurely releasing the limit due to the rope tilting in the water flow.

[0018] 3. The warning mechanism of this invention can determine whether the electromagnetic release device body has malfunctioned, causing the sealing cover to close prematurely. The prematurely closed sealing cover will leave a compression record on the press-type timer through the compression of the corresponding irregular shaft. The staff can then observe the press-type timer to know that the electromagnetic release device body has malfunctioned, which will facilitate subsequent maintenance work.

[0019] 4. The present invention can prevent seawater from entering the installation frame when the rope slides upward, thus avoiding severe corrosion of the internal structure of the installation frame. In conjunction with the positioning shaft, the rope inside the installation frame can be kept in a vertical state, preventing it from tilting and rubbing against the inner wall of the guide block, which would cause the guide block to fail to move downward with the whole equipment in advance.

[0020] 5. The present invention can drive the rotating shaft to rotate by a drive motor. After the device completes the sampling work, the released rope can be rewound onto the rotating shaft to realize the automatic retrieval and winding of the rope, which facilitates the subsequent sampling operations.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figure 1 - Figure 10As shown, this invention provides a seawater sampling device for marine forecasting services, including a mounting frame 1. A plurality of water sampling bottles 5 are fixedly connected to the surface of the mounting frame 1. Each water sampling bottle 5 has two sealing caps 8 inside, located at the upper and lower ends of the bottle. A traction rope 9 is fixedly connected to the surface of both sealing caps 8. A collar 7 is fixedly connected to the surface of the upper sealing cap 8. Two mounting plates 11 are fixedly connected to the inner wall of each water sampling bottle 5. An elastic band 10 connects each mounting plate 11 to its corresponding sealing cap 8. An electromagnetic release body 6 is fixedly connected to the inner wall of the mounting frame 1. The collar 7 is fitted onto the outside of the electromagnetic release body 6 when the sealing cap 8 is in the open state. The device needs to be adjusted in advance according to the different conditions of each water sampling bottle 5. The small-diameter section of the rope 205 is limited according to the sampling depth. The length of the small-diameter rope 205 is determined by the required water depth for sampling by the water sampling bottle 5. The sealing cap 8 needs to be opened beforehand. Two adjacent sealing caps 8 are connected by a traction rope 9. Therefore, when the upper sealing cap 8 is opened, the lower sealing cap 8 can be opened by pulling the traction rope 9, allowing the collar 7 to be fitted onto the electromagnetic release body 6. The mounting frame 1 has an anti-misclosing mechanism inside to ensure accurate water sampling depth and improve sampling reliability. The anti-misclosing mechanism includes several mounting frames 202, several ropes 205, several airbags 201, several guide blocks 210, several transmission plates 213, and several spring return shafts. 219. Several limiting plates 206 and several irregularly shaped shafts 216. Each rope 205 consists of two sections of rope with different diameters. The junction of the two sections of rope 205 is covered with sheet metal. The sheet metal prevents the rope 205 from being forcibly squeezed into the through hole on the surface of the guide block 210 due to deformation. Each rope 205 is located inside the mounting frame 202, and its top end passes through the mounting frame 202 and the guide block 210 and extends above the guide block 210. The top end of the rope 205 is fixedly connected to the bottom surface of the airbag 201. Each guide block 210 has a through hole on its surface. The diameter of the through hole is larger than the small diameter section of the rope 205 and smaller than the large diameter section of the rope 205. Each guide block 210 is located on one side of the transmission plate 213. Each spring return shaft... All 219 are rotatably connected to the inner wall of the transmission plate 213. Each limiting plate 206 is fixedly connected to the surface of the spring return shaft 219. The surface of each limiting plate 206 abuts against the surface of the irregular shaft 216. The irregular shaft 216 can rotate as the sealing cover 8 is opened. The anti-misclosing mechanism can ensure accurate water sampling depth and improve sampling reliability. When the sealing cover 8 is opened, it will drive the irregular shaft 216 to rotate through the transmission shaft 217. The rotation of the irregular shaft 216 will gradually squeeze the limiting plate 206, causing the limiting plate 206 to push the transmission plate 213 and stretch the force spring 215 until the recess of the irregular shaft 216 rotates to the limiting plate 206. At this time, the limiting plate 206 will move to the recess of the irregular shaft 216 under the action of the elastic force of the force spring 215.At this time, the sealing cap 8 is fixed to one side of the electromagnetic release body 6 by the collar 7, so the irregular shaft 216 is also in a fixed state and will not contact the limiting plate 206. In addition, the limiting plate 206 is in contact with the transmission plate 213 at this time, and the limiting plate 206 cannot rotate significantly. Therefore, even if the electromagnetic release body 6 malfunctions and releases the sealing cap 8 in advance, the sealing cap 8 cannot close smoothly. In addition, during the downward movement of the entire equipment, the airbag 201 will float on the sea surface, so the rope 205 will be pulled. The small diameter section of the rope 205 can pass smoothly through the opening on the surface of the guide block 210 under the combined action of the positioning shaft 209 and the lip-shaped sliding seal ring 212. However, when the water sampling bottle 5 moves to the designated water sampling depth, the large diameter section of the rope 205 inside will be pulled. The bottom surface of the guide block 210 contacts the small-diameter section of rope 205. Because the connection between the large-diameter section and the small-diameter section of rope 205 is covered with sheet metal, the large-diameter section of rope 205 limits the guide block 210, preventing it from moving downwards with the entire device. The downward movement of the entire device causes the transmission plate 213 and other structures to move synchronously downwards. Combined with the inclined design of the guide block 210, this pushes the transmission plate 213 and the limiting plate 206, preventing the limiting plate 206 from contacting the force plate 406. At this point, the limiting plate 206 can rotate significantly around the axis of the spring reset shaft 219. Therefore, regardless of whether the electromagnetic release device 6 releases prematurely due to a malfunction, the anti-mis-closing mechanism ensures that the water sampling bottle 5 closes at the appropriate depth, completing the sampling process.

[0025] In this embodiment, please refer to Figures 1-4 , Figure 11 and Figure 12 Each mounting frame 202 is fixedly connected to the surface of the water collection bottle 5. Each water collection bottle 5 is fixedly connected to two fixing blocks 13, which are located at the upper and lower ends of the water collection bottle 5 respectively. The inner wall of each fixing block 13 is rotatably connected to a drive shaft 217. One end of the drive shaft 217 located at the upper end passes through the mounting frame 202 and is rotatably connected to the inner wall of the mounting frame 202. The inner wall of each irregular shaft 216 is fixedly connected to the surface of the upper drive shaft 217. Each sealing cover 8 is fixedly connected to two connecting plates 12, and the surface of each connecting plate 12 is fixedly connected to the surface of the drive shaft 217. By utilizing the connection relationship between the fixing blocks 13, the drive shaft 217 and the connecting plates 12, the closed state of the sealing cover 8 can be associated with the state of the irregular shaft 216, thereby limiting the irregular shaft 216 and preventing the sealing cover 8 from closing.

[0026] Furthermore, please refer to Figure 5Each mounting frame 202 has a rotating shaft 203 rotatably connected to its inner wall. Each rotating shaft 203 has two partitions 204 fixedly connected to its surface. Each rope 205 is wrapped around the surface of the rotating shaft 203. Each mounting frame 202 has a drive motor 207 fixedly connected to its inner wall. The output end of each drive motor 207 is fixedly connected to one end of the rotating shaft 203. With the drive motor 207, the rotation of the drive motor 207 will drive the rotating shaft 203 to rotate synchronously. The rotation of the rotating shaft 203 can rewrap the unfolded rope 205 onto the rotating shaft 203 for easy use next time. When the drive motor 207 stops, it will not self-lock the rotating shaft 203. Therefore, the rope 205 can be freely unfolded from the rotating shaft 203 under the action of the airbag 201.

[0027] Furthermore, please refer to Figure 5 and Figure 6 Each mounting frame 202 has two sets of positioning blocks 208 fixedly connected to its inner wall. Each set of positioning blocks 208 contains two blocks. A positioning shaft 209 is rotatably connected to the inner wall of each pair of positioning blocks 208. The surface of each positioning shaft 209 is covered with a rubber layer. Each rope 205 passes between the two sets of positioning shafts 209. Each mounting frame 202 has two first limiting shafts 211 fixedly connected to its inner wall. Each guide block 210 is slidably connected to the surface of the two first limiting shafts 211. Each first limiting shaft 211 consists of two columns of different diameters. The lower column with the larger diameter provides support for the guide block 210. Each mounting frame 202 has a lip-shaped sliding seal ring 212 fixedly connected to its inner wall. The lip-shaped sliding seal ring 212 is a contact-type sliding seal with a lip-shaped elastic structure. Its core function is to rely on the elasticity of the seal ring's lip to tightly fit the rope 205, forming a sealing gap. It does not obstruct the up-and-down sliding of the rope 205, and can effectively isolate seawater, preventing seawater from entering the interior of the mounting frame 202 through the gap between the rope 205 and the mounting frame 202. One end of each rope 205 passes through the lip-shaped sliding seal ring 212 and extends above the lip-shaped sliding seal ring 212. The mounting frame 1 is equipped with a rope anti-sway limiting mechanism. By setting the positioning shaft 209 and the lip-shaped sliding seal ring 212, the rope 205 can be limited, so that the rope 205 can pass through the opening of the guide block 210 in a vertical state. The surface of the positioning shaft 209 is covered with a layer of rubber. When the larger diameter section of the rope 205 passes through the positioning shaft 209, the larger section of the rope 205 can still pass smoothly under the action of the rubber. In addition, the lip-shaped sliding seal ring 212 can prevent seawater from entering the interior of the mounting frame 202, and the first limiting shaft 211 can limit the movement path of the guide block 210.

[0028] In addition, please see Figure 6 and Figure 7Each transmission plate 213 has a roller 218 rotatably connected to its inner wall. The surface of each roller 218 is in contact with the inclined surface of the guide block 210. Each mounting frame 202 has two sets of second limiting shafts 214 and two sets of force springs 215 fixedly connected to its inner wall. Each set of second limiting shafts 214 and force springs 215 consists of two parts. Each second limiting shaft 214 is located in the inner cavity of the force spring 215. Each transmission plate 213 is slidably connected to the surface of the two sets of second limiting shafts 214. By providing rollers 218, the rollers 218 can reduce the friction between the guide block 210 and the transmission plate 213. The second limiting shafts 214 can limit the movement position of the transmission plate 213. The force springs 215 can make the transmission plate 213 automatically reset without external force.

[0029] It is worth noting that, please refer to Figure 4 The rope anti-sway limiting mechanism includes several fixed rings 301 and several swing rings 303. The bottom end of each fixed ring 301 is fixedly connected to the upper surface of the mounting frame 202. Several positioning springs 302 are fixedly connected to the inner ring of each fixed ring 301 and the inner wall of the swing ring 303. One end of each rope 205 passes through the swing ring 303 and extends above the swing ring 303. The inner ring of each fixed ring 301, the inner ring of the swing ring 303, and the outer ring are all covered with a rubber layer. The rope 205 does not contact the inner ring of the swing ring 303 in a normal vertical state. When the rope 205 tilts, it abuts against the inner ring of the swing ring 303. A warning mechanism is provided inside the mounting frame 1. The rope anti-sway limiting mechanism can keep the rope 205 in a vertical state. When the current in the sea is strong, the rope 205 will... Due to the tilting of the water flow, the tilted rope 205 will contact the inner ring of the swing ring 303 and push the swing ring 303 to contact the fixed ring 301. The outer ring, inner ring of the swing ring 303, and inner ring of the fixed ring 301 are all covered with a rubber layer. Therefore, the rope 205 will contact the surface of the rubber layer. Under the action of friction, the speed at which the rope 205 unfolds from the rotating shaft 203 can be slowed down. This can straighten the tilted rope 205. Furthermore, the greater the speed of the water flow in the sea, the greater the tilt angle of the rope 205, the larger the contact surface between the rope 205 and the inner ring rubber of the swing ring 303, and the greater the resistance. The friction force on the rope 205 when unfolding can be automatically adjusted according to the speed of the water flow in the sea, thereby avoiding the problem of the limit plate 206 prematurely releasing its limit state due to the tilting of the rope 205 caused by the water flow.

[0030] It is worth emphasizing that you should refer to [link / reference]. Figure 9 and Figure 10The warning mechanism includes several return springs 405, several push-button timers 403, several squeeze shafts 408, and several force plates 406. Each mounting frame 202 has a side mounting cavity inside one side wall. Each return spring 405 and push-button timer 403 is located within the side mounting cavity. The top ends of every two return springs 405 are fixedly connected to the inner wall of the mounting frame 202. The surface of each limiting plate 206 contacts the inner wall of the force plate 406 and cannot rotate significantly around the axis of the spring return shaft 219. The bottom end of each squeeze shaft 408 is fixedly connected to the upper surface of the force plate 406. Each push-button timer 403 has a push-button switch 404 on its bottom surface, and the top end of each squeeze shaft 408 contacts the bottom end of the push-button switch 404. The warning mechanism can detect abnormal movements of the electromagnetic release body 6. The system monitors and records the normal release state. When the electromagnetic release device body 6 malfunctions and prematurely releases the collar 7, the limiting plate 206 and the spring return shaft 219 are directly below the force plate 406 and in contact with the bottom surface of the force plate 406. Therefore, the limiting plate 206 cannot rotate significantly. The irregular shaft 216 will continuously exert a pushing force on the limiting plate 206 under the action of the elastic band 10. When the limiting plate 206 is pushed, it will squeeze the force plate 406 to move upward a certain distance until the surface of the force plate 406 contacts the inner wall of the mounting frame 202. Therefore, the limiting plate 206 can only rotate slightly. At this time, the irregular shaft 216 is still limited by the limiting plate 206. When the force plate 406 moves upward, it can push the pressing shaft 408 to press the pressing switch 404 at the bottom of the pressing timer 403. At this time, the pressing timer 403 will record once.

[0031] It should be noted that, please refer to Figures 7-10 Each push-button timer 403 has two reset switches 407 on its bottom surface. Two rubber sleeves 402 are fixedly connected to the inner wall of the mounting frame 202. One end of each rubber sleeve 402 is located below the corresponding reset switch 407. A transparent glass 401 is fixedly connected to the inner wall of each mounting frame 202. Each transparent glass 401 corresponds to the display screen of the push-button timer 403. The rubber sleeves 402 can be used to reset the push-button timer 403. By inserting a thin tool into the rubber sleeve 402 and then pressing down on the end of the tool, the end of the tool inside the rubber sleeve 402 will move upward under the action of the lever principle, thereby pushing the reset switch 407 and resetting the push-button timer 403.

[0032] Working principle: When using the equipment, the small diameter section of the rope 205 needs to be limited in advance according to the different sampling depths of each water sampling bottle 5. The length of the small diameter rope 205 is set according to the water depth at which the water sampling bottle 5 needs to be sampled. The sealing cover 8 needs to be opened in advance so that the collar 7 is fitted onto the electromagnetic release device body 6. When the sealing cover 8 is opened, it drives the irregular shaft 216 to rotate via the transmission shaft 217. The rotation of the irregular shaft 216 gradually squeezes the limiting plate 206, causing the limiting plate 206 to push the transmission plate 213 and stretch the force spring 215 until the recess of the irregular shaft 216 rotates to the limiting plate 206. At this point, the limiting plate 206 stops being squeezed by the irregular shaft 216, and therefore the limiting plate 206 will... Under the force of the spring 215, the shaft moves to the recess of the irregular shaft 216. At this time, the sealing cover 8 is fixed to one side of the electromagnetic release body 6 by the collar 7. Therefore, the irregular shaft 216 is also in a fixed state and will not contact the limiting plate 206. In addition, at this time, the limiting plate 206 is in contact with the force plate 406, and the spring return shaft 219 is below the force plate 406. Therefore, the limiting plate 206 cannot rotate significantly around the axis of the spring return shaft 219, but can only rotate slightly. The reason why the limiting plate 206 can rotate slightly is because the force plate 406, under the action of the two return springs 405, does not contact the surface of the mounting frame 202. Therefore, when the limiting plate 206 rotates slightly, it is due to the force of the spring return shaft 215. Figure 10As can be seen, the raised structure on the surface of the limiting plate 206 can push the force plate 406 upward until the force plate 406 contacts the surface of the mounting frame 202. At this point, the force plate 406 reaches its movement limit, so the limiting plate 206 can no longer rotate around the spring return shaft 219. Therefore, the limiting plate 206 cannot rotate significantly. So even if the electromagnetic release device 6 malfunctions and releases the sealing cover 8 in advance, the transition point between the recess and the protrusion of the irregular shaft 216 will contact the upper surface of the limiting plate 206, thus squeezing the limiting plate 206 to rotate around the axis of the spring return shaft 219. However, at this time, the limiting plate 206 is limited by the force plate 406 and cannot rotate significantly. Therefore, the limiting plate 206 will exert pressure on the irregular shaft 216. The 16-position limit prevents the irregular shaft 216, drive shaft 217, and sealing cover 8 from resetting prematurely. Therefore, even if the electromagnetic release device 6 malfunctions and releases the sealing cover 8 prematurely, the sealing cover 8 cannot close smoothly during use. Furthermore, during the downward movement of the entire device, the airbag 201 floats on the surface, causing the rope 205 to be pulled. The smaller diameter section of the rope 205, under the combined action of the positioning shaft 209 and the lip-shaped sliding seal ring 212, can smoothly pass through the opening on the surface of the guide block 210. When the water sampling bottle 5 moves to the designated sampling depth, the larger diameter section of the rope 205 inside will contact the bottom surface of the guide block 210. Since the connection between the larger and smaller diameter sections of the rope 205 is covered with sheet metal... Therefore, the large-diameter section of rope 205 limits the guide block 210, preventing it from continuing to move downwards with the equipment as it moves downwards. The downward movement of the equipment causes the transmission plate 213 and other structures to move synchronously downwards. Combined with the inclined design of the guide block 210, this pushes the transmission plate 213 and the limiting plate 206, causing the limiting plate 206 and the spring return shaft 219 to move towards the irregular shaft 216 until the protruding position of the limiting plate 206 and the spring return shaft 219 are within the installation space of the irregular shaft 216. At this point, the limiting plate 206 is no longer in contact with the force plate 406, and can rotate significantly around the axis of the spring return shaft 219. Therefore, the irregular shaft 216 can... Under the action of force, the limiting plate 206 rotates significantly until the irregular shaft 216 is reset, ultimately allowing the sealing cover 8 to complete the sampling work at the specified depth. Therefore, if the electromagnetic release device 6 malfunctions and prematurely releases the sealing cover 8, the anti-mis-closing mechanism can also prevent the sealing cover 8 from prematurely sealing the water collection bottle 5. So, regardless of whether the electromagnetic release device 6 malfunctions and prematurely releases the sealing cover 8, the anti-mis-closing mechanism will ensure that the water collection bottle 5 is sealed at the appropriate depth, completing the sampling work. Furthermore, when the guide block 210 is limited by the large-diameter section of the rope 205 and contacts the inner top wall of the mounting frame 202, it means that the rope 205 can no longer be stretched. Since the other water collection bottles 5 have not yet completed the water collection work, the airbag 201 that has already completed sampling will be pulled into the seawater.However, because there is a sufficiently long rope 205 connecting the airbag 201 to the overall equipment, the airbag 201 will not be pulled into the high-pressure area, and there is no need to worry about damage to the airbag 201.

[0033] When the entire device moves into the sea, the rope 205 will unfold from the rotating shaft 203 under the action of the airbag 201 and move into the sea. When the current in the sea is strong, the rope 205 will tilt due to the current. The tilted rope 205 will contact the inner ring of the swing ring 303 and push the swing ring 303 to contact the fixed ring 301. The outer ring, inner ring of the swing ring 303 and the inner ring of the fixed ring 301 are all covered with a rubber layer. Therefore, the rope 205 will contact the surface of the rubber layer. Under the action of friction, the speed at which the rope 205 unfolds from the rotating shaft 203 can be slowed down. This can straighten the tilted rope 205. Moreover, the greater the speed of the current in the sea, the greater the angle of the rope 205 tilt, the larger the contact surface between the rope 205 and the inner ring rubber of the swing ring 303, and the greater the resistance. The friction force on the rope 205 when unfolding can be automatically adjusted according to the speed of the current in the sea, thereby avoiding the problem of the limit plate 206 being released prematurely due to the tilt of the rope 205 caused by the current.

[0034] When the electromagnetic release body 6 is in normal working condition, it will release the collar 7 at a specified depth. At this time, the limiting plate 206 and the spring return shaft 219, under the action of the anti-misclosing mechanism, have moved into the space inside the mounting frame 202 where the irregular shaft 216 is located. At this time, the limiting plate 206 can rotate significantly around the spring return shaft 219, so the limiting plate 206 has automatically released its limiting state. Therefore, when the sealing cover 8 automatically closes under the action of the elastic band 10, it will drive the irregular shaft 216 to contact the surface of the limiting plate 206. At this time, since the limiting plate 206 and the spring return shaft 219 are already in the cavity of the mounting frame 202, and the surface of the limiting plate 206 is no longer in contact with the surface of the force plate 406, the limiting plate 206... The limit plate 206 can rotate freely around the axis of the spring return shaft 219. Therefore, under the pressure of the irregular shaft 216, the limit plate 206 can rotate downwards, allowing the irregular shaft 216 to return to its original position. At this time, the sealing cover 8 will automatically complete the sealing work. Therefore, when the electromagnetic release body 6 releases the sealing cover 8 normally, the limit plate 206 cannot push the force plate 406 upwards, so the press-type timer 403 will not be triggered, and the warning mechanism will not be triggered either. Conversely, when the entire device has not moved to the specified depth but the electromagnetic release body 6 abnormally releases the collar 7, the limit plate 206, the spring return shaft 219, and the transmission plate 213 have not yet moved under the action of the guide block 210. Therefore, the limit plate 206 is still in contact with the surface of the force plate 406. Therefore, the limiting plate 206 cannot rotate freely, so the irregular shaft 216 will be limited by the limiting plate 206 and cannot reset normally. This further limits the sealing cover 8 from sealing normally. When the irregular shaft 216 applies pressure to the limiting plate 206, the limiting plate 206 can rotate slightly around the axis of the spring reset shaft 219 below the force plate 406. When the limiting plate 206 rotates, it can push the force plate 406 upward until the surface of the force plate 406 is in close contact with the surface of the mounting frame 202. At this time, although the limiting plate 206 has rotated slightly, it can still limit the irregular shaft 216. Furthermore, when the limiting plate 206 rotates, it will push the force plate 406 upward, and the force plate 406 can push the extrusion shaft 4. 08. Press the push switch 404 at the bottom of the press-type timer 403. At this time, the press-type timer 403 will record a fault information of premature release of the electromagnetic release body 6. Only when the entire equipment reaches the specified depth, the larger diameter section of the rope 205 corresponding to the water sampling bottle 5 pushes the guide block 210 to move, and further drives the transmission plate 213, the limit plate 206 and the spring return shaft 219 to move, can the limit plate 206 be released. At this time, the irregular shaft 216 can drive the limit plate 206 to rotate under the action of the elastic band 10 to complete the reset work. When the irregular shaft 216 completes the reset, the spring reset structure inside the spring return shaft 219 can also drive the limit plate 206 to reset, and at the same time complete the seawater sampling work at the specified depth.While completing the data collection, the push-button timer 403 can send a message to the outside world indicating that the electromagnetic release device 6 has been released in advance. When it is necessary to reset the push-button timer 403, a thin tool is inserted into the rubber sleeve 402, and then the end of the tool is pressed down. The end of the tool inside the rubber sleeve 402 will move upward under the action of the lever principle, thereby pushing the reset switch 407 and resetting the push-button timer 403.
