Description

Technical Field

[0001] The invention belongs to the technical field of marine equipment, and in particular relates to a cable releasing device for a marine seawater sampler. Background Art

[0002] In order to monitor the changes in various components of the environment, it is necessary to sample the environment, especially for the sampling of seawater. Since the air above the ocean has a higher salt content than other areas, conventional parts will wear out faster when working in the marine environment. When sampling seawater, the seawater sampler needs to be fixed on the cable, and then the cable release device is used to determine the depth of the seawater sampler. When multiple or large-scale sampling is performed at the same sampling point, the cable release device needs to be locked to reduce the pressure on the motor. The existing locking methods are all locked by clamping friction, and this method relies on the static friction between two or more parts to stabilize the release device. However, due to the influence of the working environment, high-salt air will accelerate the wear between the parts, making the force required for the friction between the parts greater, and when the locking force remains unchanged, the locking effect will be poor, and the friction parts need to be replaced frequently, increasing the work intensity of the staff. Summary of the invention

[0003] The purpose of the present invention is to provide a cable release device for a marine seawater sampler to solve the problem that the wear rate between the parts of the existing cable release device is higher than the normal value during operation and the locking effect is poor.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] A cable releasing device for a marine seawater sampler comprises a frame, the frame is rotatably connected to a rotating shaft, a control module is installed on the frame, the rotating shaft is fixedly connected to a rotating drum, a cable is wound around the rotating drum, a first fixed frame is fixedly connected to a side of the frame, a first gear is fixedly connected to a first rotating member on a side of the first gear away from the rotating drum, the first rotating member is rotatably connected to the first fixed frame, the first fixed frame is fixedly connected to a fixing member, the first rotating member is sealingly rotatably connected to the fixing member, a cavity is provided between the first rotating member and the fixing member, a transmission medium is provided in the cavity, a first plate is fixedly connected to a side of the first rotating member close to the fixing member, the first plate is in contact and cooperate with the fixing member, the fixing member is sealingly slidably connected to the second plate, the second plate is in contact and cooperate with the first rotating member, a power mechanism for rotating the rotating drum is provided on a side of the frame close to the first fixed frame, and an arrangement mechanism for limiting the position of the cable is provided on one side of the frame.

[0006] The present invention has the following advantages:

[0007] As described above, the present invention relates to a cable release device for a marine seawater sampler. The device blocks the cavity between the first rotating part and the fixed part through the second plate, thereby locking the drum, and the sampler starts to work in the sea area of ​​the target depth, preventing wear and poor locking effect caused by conventional friction locking, while avoiding unnecessary losses, increasing the service life of parts, and reducing the frequency of parts replacement; the permanent magnet is used to generate an induced current in the coil when it moves, and the induced current is transmitted to the control module to control the rotation of the output shaft of the drive motor, thereby releasing or reeling the cable to compensate for the height change caused by the deflection of the sampler due to the impact of the undercurrent, thereby stabilizing the height of the sampler. The position of the sample taken by the sampler is relatively fixed, thereby improving the representativeness of the sample; the guide block is moved left and right by rotating the reciprocating screw, so that the cable is gradually released or reeled in on the outside of the drum, and the arrangement of the cable is regulated to prevent the cable from getting tangled during the reeling process, thereby affecting normal work; the rotating ring is used to drive the fourth plate arranged symmetrically with the center to rotate, and the air in the adjacent area of ​​the first cavity is squeezed, and finally the air is blown toward the cable from the adjacent air outlet, so as to remove the residual seawater on the cable, avoid the accumulation of seawater on the cable, and cause the cable to be corroded during the subsequent storage process, thereby reducing the service life of the cable.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Existing cable release devices usually use friction when locking, but due to the influence of the working environment, high-salt air will accelerate the wear between the parts, resulting in poor locking effect. At the same time, friction parts need to be replaced frequently, increasing the work intensity of the staff. In view of this problem, the present invention proposes a cable release device for a marine seawater sampler.

[0026] Example 1

[0027] like Figures 1 to 5 As shown, the cable release device of the marine seawater sampler in this embodiment 1 includes a frame 1, the upper side of the frame 1 is rotatably connected to a rotating shaft 2, the frame 1 is installed with a control module (not shown in the drawings), the rotating shaft 2 is fixedly connected to a rotating drum 3, a cable 4 is wound around the rotating drum 3, a guide groove is arranged on the outer side of the rotating drum 3, and the guide groove is spirally provided for guiding the wound cable 4 to prevent the cable 4 from being knotted during the winding process, a first fixed frame 5 is fixedly connected to the upper part of the right side of the frame 1, a first gear 6 is fixedly connected to the right side of the rotating shaft 2, a first rotating member 7 rotatably connected to the first fixed frame 5 is fixedly connected to the right side of the first gear 6, the first fixed frame 5 is fixedly connected to a fixing member 8 that is sealingly rotatably connected to the first rotating member 7, there is a cavity between the first rotating member 7 and the fixing member 8, and the cavity A transmission medium is provided, and the transmission medium is hydraulic oil. A first plate 9 contacting and cooperating with a fixed part 8 is fixedly connected to the upper part of the right side of the first rotating part 7. The first plate 9 is always in close contact with the fixed part 8 during the movement. A second plate 10 contacting and cooperating with the first rotating part 7 is sealingly and slidably connected to the lower part of the fixed part 8. The second plate 10 is always in close contact with the first rotating part 7 during the movement. The cavity between the first rotating part 7 and the fixed part 8 is blocked by the second plate 10, so that the first rotating part 7 cannot rotate, thereby hydraulically locking the rotating drum 3, so as to prevent the conventional friction locking method from wearing and causing poor locking effect. A power mechanism for rotating the rotating drum 3 is provided at the lower part of the right side of the frame 1, and an arrangement mechanism for limiting the position of the cable 4 is provided on the front side of the frame 1.

[0028] like Figures 2 to 4 and Figure 6As shown, the power mechanism includes a second fixed frame 1101, which is fixedly connected to the lower part of the right side of the frame body 1, and a driving motor 1102 electrically connected to the control module is installed on the upper part of the second fixed frame 1101. The output shaft of the driving motor 1102 is fixedly connected to a rotating shell 1103 rotatably connected to the second fixed frame 1101, and the left side of the rotating shell 1103 is slidably connected to a first sliding rod 1104, and the right end of the first sliding rod 1104 is fixedly connected to a sliding plate 1105 splined to the rotating shell 1103, and the left end of the first sliding rod 1104 is fixedly connected to a second gear 1106 that cooperates with the first gear 6 in transmission, and the middle part of the first sliding rod 1104 is rotatably connected to a moving frame 1107 fixedly connected to the second plate 10, and a trigger component for moving the sliding plate 1105 is arranged in the rotating shell 1103.

[0029] like Figure 4 and Figure 6 As shown, the trigger assembly includes a first electromagnet 1201, which is installed on the right side of the sliding plate 1105. A second electromagnet 1202 is installed in the rotating shell 1103. The magnetic poles of the first electromagnet 1201 and the second electromagnet 1202 are opposite. The first electromagnet 1201 and the second electromagnet 1202 are moved to the right by utilizing the magnetic force (suction force) generated by electricity passing through the first electromagnet 1201 and the second electromagnet 1202. The first electromagnet 1201 and the second electromagnet 1202 are both electrically connected to the control module. A first elastic element 1203 is fixedly connected between the first electromagnet 1201 and the second electromagnet 1202. The first elastic element 1203 is a spring for resetting the first electromagnet 1201.

[0030] like Figure 7 and Figure 8 As shown, the arrangement mechanism includes a guide frame 1301, which is fixedly connected to the lower part of the front side of the frame body 1, and the guide frame 1301 is slidably connected to a guide block 1302 that cooperates with the cable 4 to limit the position, and the rear part of the upper side of the guide block 1302 is rotatably connected to a roller that cooperates with the cable 4 to limit the position, and the front side of the guide frame 1301 is rotatably connected to a reciprocating screw 1303 that is threadedly connected to the guide block 1302, and the reciprocating screw 1303 is connected to the rotating shaft 2 through a pulley and belt transmission. The guide block 1302 that moves left and right is used to make the cables 4 in adjacent areas move left and right synchronously, so that the cables 4 are gradually wound around the rotating drum 3, so as to avoid the cables 4 from being knotted during the winding process, thereby affecting the normal operation, and the lower part of the front side of the guide frame 1301 is provided with a detection component for identifying the deflection of the cable 4.

[0031] like Figures 7 to 9As shown, the detection assembly includes two sliding blocks 1401 arranged in a left and right mirror image, the two sliding blocks 1401 are both slidably connected to the guide frame 1301, a second elastic element 1402 is fixedly connected between the sliding block 1401 and the guide frame 1301, the second elastic element 1402 is a spring, and is used to reset the adjacent sliding blocks 1401, an L-shaped rod 1403 is fixedly connected to the lower side of the sliding block 1401, and the two L-shaped rods 1403 are commonly fixedly connected to a moving rod 1404 that is squeezed and matched with the cable 4, and the right The L-shaped rod 1403 on the side is fixedly connected to the connecting rod 1405, and the lower part of the right side of the frame 1 is fixedly connected to the first shell 1406 through a fixed plate. A buffer medium is arranged in the first shell 1406, and the buffer medium is hydraulic oil. The first shell 1406 is sealed and slidably connected to the second sliding rod 1407 fixedly connected to the connecting rod 1405. A coil 1408 electrically connected to the control module is wound in the first shell 1406, and an induction component for adjusting the rotating drum 3 is arranged in the first shell 1406.

[0032] like Fig.10 As shown, the induction component includes a permanent magnet 1501, which is sealed and slidably connected in the first shell 1406. A through hole is set on the upper part of the permanent magnet 1501, and the diameter of the through hole is much smaller than the inner diameter of the first shell 1406. The rear side of the second sliding rod 1407 is slidably connected with a third sliding rod 1502 fixedly connected to the permanent magnet 1501. A third elastic element 1503 is fixedly connected between the third sliding rod 1502 and the second sliding rod 1407. The third elastic element 1503 is a spring, which is used to apply elastic force to the third sliding rod 1502. Through the resistance of the hydraulic oil in the first shell 1406 to the permanent magnet 1501 and the elastic force of the third elastic element 1503 on the third sliding rod 1502, the permanent magnet 1501 continues to move forward slowly, so that the coil 1408 generates an induced current, thereby transmitting an electrical signal to the control module and controlling the rotation of the output shaft of the drive motor 1102, releasing and winding the cable 4, thereby stabilizing the working height of the sampler and improving the sampling effect.

[0033] The device is installed on the hull by bolts. When the device needs to be used to release the seawater sampler (for the sake of ease of description, the sampler is used instead below), the staff first drives the sampling hull to the sea area to be sampled, then moors the ship, fixes the seawater sampler to the lower end of the cable 4, and then starts the drive motor 1102, the first electromagnet 1201 and the second electromagnet 1202 through the control module. The output shaft of the drive motor 1102 starts to rotate counterclockwise (left viewing direction), and the output shaft of the drive motor 1102 drives the rotating shell 1103 to rotate counterclockwise, and the rotating shell 1103 drives the sliding plate 1105 to rotate counterclockwise. 1104 rotates clockwise, and the sliding plate 1105 drives the second gear 1106 to rotate counterclockwise through the first sliding rod 1104. During the process, the first electromagnet 1201 and the second electromagnet 1202 both generate magnetic force, and the magnetic poles of the two are opposite. At this time, the first electromagnet 1201 moves to the right under the action of the magnetic force (suction) of the second electromagnet 1202, and the first elastic element 1203 is compressed. The first electromagnet 1201 drives the first sliding rod 1104 to move to the right through the sliding plate 1105, and the first sliding rod 1104 drives the second gear 1106 and the moving frame 1107 to move to the right together, and the moving frame 1107 drives the second plate 10 moves to the right together, the second plate 10 loses the blocking of the cavity between the first rotating member 7 and the fixing member 8, the second gear 1106 meshes with the first gear 6, then the first gear 6 starts to rotate clockwise, the first gear 6 drives the drum 3 to rotate clockwise through the rotating shaft 2, the drum 3 releases the sampler, after the seawater sampler moves downward to the target area, the staff turns off the drive motor 1102, the first electromagnet 1201 and the second electromagnet 1202, the output shaft of the drive motor 1102 stops rotating, the magnetic force of the first electromagnet 1201 and the second electromagnet 1202 disappears, then the first electromagnet 1201 is in the first elastic Element 1203 begins to move to the left under the action of the elastic force, and the first electromagnet 1201 drives the first sliding rod 1104 and the parts thereon to move to the left together, and the second plate 10 gradually blocks the cavity between the first rotating part 7 and the fixed part 8. Since the hydraulic oil in the cavity cannot be compressed, the first rotating part 7 and the parts thereon stop rotating, thereby locking the drum 3. The sampler starts to work in the sea area at the target depth, preventing poor locking effect caused by wear when using conventional friction locking methods, and avoiding unnecessary losses, thereby increasing the service life of parts, reducing the frequency of parts replacement, and reducing the workload of staff.

[0034] In order to improve the representativeness of the samples taken by the sampler, the movement of the permanent magnet 1501 is used to make the coil 1408 generate an induced current, and then the induced current is transmitted to the control module to control the rotation of the output shaft of the drive motor 1102, and the cable 4 is released and reeled up, so as to stabilize the working height of the sampler and improve the sampling effect. The specific steps are as follows: during the operation of the sampler, when an undercurrent is encountered (taking the undercurrent in the forward direction as an example), the seawater impacts the sampler in the forward direction, and then the cable 4 starts to move with the guide block 1302 as the guide block. The rotation center deflects counterclockwise (left viewing direction), the cable 4 begins to squeeze the moving rod 1404 forward, the moving rod 1404 begins to move forward, the moving rod 1404 drives the two L-shaped rods 1403 to move forward together, the L-shaped rod 1403 drives the adjacent sliding block 1401 to move forward together, the sliding block 1401 compresses the adjacent second elastic element 1402, the L-shaped rod 1403 on the right drives the connecting rod 1405 to move forward together, the connecting rod 1405 drives the second sliding rod 1407 to move forward together, and the second sliding rod 1407 moves forward together. The second sliding rod 1407 drives the third sliding rod 1502 to move forward together through the third elastic element 1503. Since the diameter of the through hole on the permanent magnet 1501 is much smaller than the inner diameter of the first shell 1406, the hydraulic oil in the first shell 1406 produces continuous resistance to the permanent magnet 1501, that is, the speed of the permanent magnet 1501 moving forward is lower than the speed of the second sliding rod 1407 moving forward. During the process, the third elastic element 1503 is continuously compressed. When the sampler deflects counterclockwise to a balanced state, the second sliding rod 1407 stops moving forward, and the third sliding rod 1502 continues to move forward under the action of the elastic force of the third elastic element 1503. During the process, an induced current is generated on the coil 1408 and transmitted to the control module. Subsequently, the control module starts the output shaft of the drive motor 1102 to rotate counterclockwise again (left viewing direction), that is, the cable 4 is released again to compensate for the height change caused by the deflection of the sampler due to the impact of the undercurrent, thereby stabilizing the height of the sampler and preventing the sample taken from being unrepresentative due to the change in the position of the sampler.

[0035] When the undercurrent disappears, the cable 4 is gradually reset under the action of the gravity of the sampler (it deflects clockwise with the guide block 1302 as the rotation center), the cable 4 gradually loses the squeeze on the moving rod 1404, and the sliding block 1401 begins to move backward under the action of the elastic force of the adjacent second elastic element 1402, the sliding block 1401 drives the adjacent L-shaped rod 1403 to move backward together, the two L-shaped rods 1403 jointly drive the moving rod 1404 to move backward together, the L-shaped rod 1403 on the right side drives the connecting rod 1405 to move backward together, the connecting rod 1405 drives the second sliding rod 1407 to move backward together, and the second sliding rod 14 07 drives the third sliding rod 1502 to move backward together, and the third sliding rod 1502 drives the permanent magnet 1501 to move backward together, and a reverse induced current is generated on the coil 1408, and the induced current is transmitted to the control module, and then the control module starts the output shaft of the drive motor 1102 to rotate clockwise, and reels the cable 4 to maintain the height of the sampler. After the sampler completes the sampling work, the staff starts the drive motor 1102 through the control module, and the output shaft of the drive motor 1102 starts to rotate clockwise, and the rotating drum 3 starts to rotate counterclockwise and reels the cable 4 until the sampler is removed and the drive motor 1102 is turned off.

[0036] In order to improve the arrangement effect of the cable 4, the guide block 1302 is moved left and right by rotating the reciprocating screw 1303, so that the cable 4 is gradually released or reeled in on the outside of the drum 3, and the arrangement of the cable 4 is regulated to prevent the cable 4 from being tangled during the reeling process, thereby affecting normal work. The specific steps are as follows: during the clockwise rotation of the shaft 2 (left viewing direction), the shaft 2 transmits power to the reciprocating screw 1303 through the pulley belt, and then the reciprocating screw 1303 starts to rotate clockwise, and then the guide block 1302 starts to rotate along The guide frame 1301 slides back and forth left and right, and the cable 4 always moves on the roller during the process. During the counterclockwise rotation of the rotating shaft 2, the reciprocating screw 1303 also rotates counterclockwise, and the guide block 1302 also moves back and forth left and right, so that the cable 4 is wound along the guide groove on the rotating drum 3, avoiding the cable 4 from getting tangled during the winding process, thereby affecting the normal winding work and even causing damage to the entire device. When the sampling work is completed, the staff removes the sampler from the cable 4 and resets the parts of the device and drives away from the ship.

The air holes 16023 and the first cavity 16021 are both connected to the second cavity 16022. The upper side of the second shell 1602 is sealed and rotatably connected with a rotating ring 1603. The second shell 1602 is fixedly connected with two third plates 1604 arranged symmetrically in the front and rear centers. The rotating ring 1603 is fixedly connected with two fourth plates 1605 arranged symmetrically in the front and rear centers. The fourth plate 1605 squeezes the air in the adjacent area of ​​the first cavity 16021 when rotating, so that the air enters the second cavity 16022 and is finally discharged through the air outlet 16023, and the cable 4 in the adjacent area is cleaned. The third plate 1604 and the fourth plate 1605 are both located in the first cavity 16021. The rotating ring 1603 is equipped with two groups of first one-way valves 1606 arranged symmetrically in the front and rear centers, each group contains two first one-way valves 1606 arranged in a mirror image on the left and right. The flow direction of the first one-way valve 1606 is from top to bottom.

The flow direction of the second one-way valve 1607 and the third one-way valve 1608 is from top to bottom. The second one-way valve 1607 and the third one-way valve 1608 are respectively located at the connecting parts adjacent to the first cavity 16021 and the second cavity 16022, and a transmission assembly for moving the rotating ring 1603 is provided at the lower part of the front side of the frame 1.

[0041] In order to extend the service life of the cable 4, the rotating second rotating member 1702 drives the rotating ring 1603 to rotate reciprocatingly, and the fourth plate 1605 squeezes the air in the first cavity 16021, so that the air is discharged from the air outlet 16023 and the cable 4 in the adjacent area is cleaned, so as to remove the residual seawater on the cable 4, prevent the seawater from corroding the cable 4 during the subsequent storage of the device, thereby reducing the service life of the cable 4. The specific steps are as follows: during the counterclockwise rotation of the rotating drum 3 and the movement of the guide block 1302 to the left, the guide block 1302 drives the fixed rod 1601 to move to the left together, the fixed rod 1601 drives the second shell 1602 to move to the left together, the second shell 1602 drives the connecting member 1701 to move to the left together, and the connecting member 1701 drives the second rotating member 1702 and the third gear 1703 to move to the left together. During the process, the third gear 1703 rolls along the rack 1706, that is, The third gear 1703 rotates clockwise (looking down), the third gear 1703 drives the second rotating member 1702 to rotate clockwise together, the second rotating member 1702 drives the connecting rod 1705 to rotate clockwise together, the connecting rod 1705 drives the intermediate tube 1704 to start rotating counterclockwise, the intermediate tube 1704 drives the rotating ring 1603 to rotate counterclockwise together, the rotating ring 1603 drives the two fourth plates 1605 to rotate counterclockwise together, the two fourth plates 1605 start to squeeze the air in the adjacent area of ​​the first cavity 16021, the squeezed air enters the second cavity 16022 through the adjacent second one-way valve 1607, and then the air is blown to the cable 4 through the adjacent air outlet 16023, so as to remove the residual seawater on the cable 4 and avoid the accumulation of seawater on the cable 4, which will cause the cable 4 to be corroded during the subsequent storage process, thereby reducing the service life of the cable 4, and even causing the cable 4 to break during the subsequent use.

[0042] During the counterclockwise rotation of the rotating ring 1603, the air also enters the adjacent area of ​​the first cavity 16021 through the first one-way valve 1606 on the left front side and the right rear side. As the third gear 1703 continues to roll leftward along the rack 1706, the intermediate cylinder 1704 moves counterclockwise to the limit position, and then the intermediate cylinder 1704 starts to move clockwise, and the intermediate cylinder 1704 drives the rotating ring 1603 and the parts thereon to rotate clockwise together, and the two fourth plates 1605 begin to squeeze the air that previously entered the first cavity 16021 through the first one-way valve 1606. At the same time, the outside air enters the adjacent areas in the first cavity 16021 through the first one-way valve 1606 on the right front side and the left rear side, and the squeezed air enters the second cavity 16022 through the adjacent third one-way valve 1608, so as to continuously blow air on the cable 4 and improve the effect of removing seawater on the cable 4. During the counterclockwise rotation of the drum 3, the cleaning member 18 continuously scrapes the outside of the cable 4 to clean the impurities (seaweed, etc.) adhering to the outside of the cable 4, so as to prevent the impurities from accumulating on the cable 4 and increasing its surface roughness and reducing the tensile strength.
