Description

Technical Field

[0001] The present invention relates to the technical field of marine and inland water survey equipment, in particular to a marine winch based on hydrological and geological surveys. Background Art

[0002] In hydrological and geological surveys, ship winches are one of the important equipment, used to lower various survey instruments and samplers to specified water depths to obtain hydrological data such as water temperature, salinity, flow rate, etc. and geological samples such as sediments and rocks.

[0003] However, when the winch lowers the equipment, the water flow creates a continuous impact on the equipment, and the equipment will also be displaced and shake under the action of the water flow. Turbulence is easily formed near river bends and obstacles, such as reefs and bridge piers. The direction and speed of the water flow are constantly changing. After the equipment enters the turbulent area, it will be subjected to forces in multiple directions and sizes, resulting in increased shaking. The existing winch is difficult to achieve the effect of resisting the impact of water flow during and after lowering the hydrological equipment, resulting in the water flow impact causing the hydrological equipment to displace and shake, thereby reducing the monitoring accuracy of the hydrological equipment and increasing the difficulty of monitoring.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing marine winches on the market, and even if they can be solved, they need to be solved with the help of external tools, which makes it impossible to achieve the desired effect.

[0040] A plurality of sliding grooves 2113 are provided on one side of the rotating ring 2111. The inner wall of the sliding groove 2113 is slidably connected to a sliding block 2114. The inner cavity of one of the sliding grooves 2113 is rotatably connected to a rotating column 2115. A torque sensor 2121 is provided at one end of the rotating column 2115. One end of the torque sensor 2121 is fixedly connected to the inner wall of the sliding groove 2113. The measuring axis of the torque sensor 2121 is fixedly connected to the rotating column 2115. The torque sensor 2121 is electrically connected to the controller 17. The surface of the rotating column 2115 is fixedly connected to a gear. The push rod 2117 is fixedly connected to the wheel 2116, and one end of one of the sliding blocks 2114 is fixedly connected to the push rod 2117. The surface of the push rod 2117 is provided with a plurality of tooth grooves 2118, which mesh with the surface of the gear 2116. One end of the plurality of sliding blocks 2114 is fixedly connected to the push ring 2119. By setting the sliding groove 2113, the sliding block 2114, the rotating column 2115, the gear 2116, the push rod 2117 and the tooth groove 2118 and the torque sensor 2121, when the water flow impact is generated, the water flow impact force acts on the push rod 2117 immediately. On the dynamic ring 2119, by moving the push ring 2119 horizontally, the sliding block 2114 is pushed to move in the inner cavity of the sliding groove 2113. The movement of the sliding block 2114 pushes the push rod 2117 to move. The movement of the push rod 2117, through the engagement of the tooth groove 2118 with the gear 2116, realizes the rotation of the gear 2116. The rotation of the gear 2116 drives the rotating column 2115 to rotate. The rotation of the rotating column 2115 causes the measuring axis of the torque sensor 2121 to rotate, thereby realizing the monitoring of the rotation of the rotating column 2115. The torque sensor 2121 It usually includes an elastic body. When the measuring shaft rotates, torque is applied to the elastic body. A strain gauge torque sensor is used here. The strain gauge torque sensor detects strain by means of a strain gauge attached to the elastic body. When the elastic body is deformed by the torque, the strain gauge is deformed accordingly, causing its resistance value to change. The strain gauges are formed into a Wheatstone bridge circuit. The change in resistance will cause the bridge to lose balance, thereby outputting an electrical signal proportional to the strain. Subsequently, the signal is converted into a signal that is easier to measure and process through signal processing circuits such as amplification and filtering, and is transmitted to the controller 17.

[0041] A first torsion spring 2120 is sleeved on the surface of the rotating column 2115, one end of the first torsion spring 2120 is fixedly connected to the surface of the rotating column 2115, and the other end of the first torsion spring 2120 is fixedly connected to the inner wall of the sliding groove 2113; by setting the first torsion spring 2120, the rotation of the rotating column 2115 drives the first torsion spring 2120 to deform, and when the impact of the water flow weakens, the reaction force of the first torsion spring 2120 can realize the reset of the rotation angle of the rotating column 2115.

[0042] Two limiting grooves 2122 are relatively opened on the inner side of the sliding groove 2113, and the inner cavity of the limiting groove 2122 is slidingly connected to the limiting block 2123, and one side of the limiting block 2123 is fixedly connected to one side of the sliding block 2114; by setting the limiting groove 2122 and the limiting block 2123, the moving trajectory of the sliding block 2114 can be guided to ensure the stability of the sliding block 2114 during movement, and the displacement distance of the sliding block 2114 is limited by the limiting groove 2122.

[0043] A placement slot 2124 is provided on the top of the positioning frame 2104 , and a gyro sensor 2125 is fixedly connected to the inner cavity of the placement slot 2124 . The gyro sensor 2125 is electrically connected to the controller 17 , and the gyro sensor 2125 is used to monitor the angular velocity of the hydrological monitoring component 2105 in water.

[0044] The specific implementation of this embodiment is as follows: when the hydrological monitoring component 2105 needs to be placed in the water area, the rotation angle locking between the rotating rod 2107 and the mounting block 2106 is canceled, and the threaded connection between the bolt 2108 and the nut 2109 is canceled to achieve the rotation between the rotating rod 2107 and the mounting block 2106. A gasket can be set between the nut 2109 and the mounting block 2106 to increase stability. The user positions the hydrological monitoring component 2105 at the bottom of the positioning frame 2104 through the external connecting piece, and then repositions the rotating rod 2107 and the mounting block 2106 through the bolt 2108 and the nut 2109 to ensure that the rotating rod 2107 is vertically downward. One side of the rotating rod 2107 is fixedly connected to the angle limit block 212 3. When the top of the angle limit block 2123 contacts the bottom of the positioning frame 2104, the rotating rod 2107 is in a vertical state. Then, the positioning unit 22 is used to clamp and position the hydrological monitoring component 2105 in multiple directions. Then, the center of gravity adjustment unit 23 is installed. Then, the hydraulic rod 12 is started by the controller 17. The telescopic end of the hydraulic rod 12 is extended until it moves above the target water area. The first motor 13 is started by the controller 17. The rotation of the output shaft of the first motor 13 drives the winding roller 14 to unwind the cable 15. Through the gravity of the hydrological monitoring component 2105 and the self-adjusting unit 21, the positioning unit 22 and the center of gravity adjustment unit 23, the cable 15 enters the water area vertically downward. After entering the water area, when it encounters the impact of the horizontal water flow, The water flow impact causes the push ring 2119 to move laterally, pushing the sliding block 2114 to move in the inner cavity of the sliding groove 2113. When moving, the sliding block 2114 is guided and the displacement distance is limited by the limit block 2123 and the limit groove 2122. The movement of the sliding block 2114 drives the push rod 2117 to move. The movement of the push rod 2117 realizes the rotation of the gear 2116 through the engagement of the tooth groove 2118 with the gear 2116. The rotation of the gear 2116 drives the rotating column 2115 to rotate. The rotation of the rotating column 2115 causes the measuring shaft of the torque sensor 2121 to rotate, thereby realizing the monitoring of the rotation of the rotating column 2115. The torque sensor 2121 usually includes an elastomer. When the measuring shaft rotates, it will press the elastic body. Torsion is applied to the body, and a strain gauge torque sensor is used here. The strain gauge torque sensor detects strain by pasting a strain gauge on the elastic body. When the elastic body is deformed by the torque, the strain gauge is deformed accordingly, causing its resistance value to change. The strain gauges are combined into a Wheatstone bridge circuit. The change in resistance will cause the bridge to lose balance, thereby outputting an electrical signal proportional to the strain. Subsequently, after amplification, filtering and other signal processing circuits, the signal is converted into a signal that is easier to measure and process, and transmitted to the controller 17. The controller 17 starts the shaftless motor 2101, and the shaftless motor 2101 drives the fan blades 2112 to rotate, forming a booster effect, thereby achieving the adjustment of the lateral displacement of the hydrological monitoring component 2105 and achieving resistance to the impact force of the water flow.When the water flow in the water area is complex, the gyro sensor 2125 detects that the positioning frame 2104 is shaking. At this time, the controller 17 simultaneously starts the four shaftless motors 2101 to resist the complex water flow and maximize the balance of the hydrological monitoring unit 2105.

[0045] Example 2: Please refer to Figures 1-10 The present invention provides a technical solution: a marine winch based on hydrological and geological surveys. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0046] As a further limitation of the stabilizing mechanism 2 of the present invention, the positioning unit 22 includes a waterproof electric telescopic rod 2201 fixedly connected to the surface of the positioning ring 2110, the telescopic end of the waterproof electric telescopic rod 2201 is fixedly connected to a clamping block 2202, and the surface of the clamping block 2202 is fixedly connected to an anti-slip pad 2203; by setting the positioning unit 22, the positioning of the hydrological monitoring component 2105 can be achieved, the shaking of the hydrological monitoring component 2105 can be reduced, and the accuracy of the hydrological monitoring component 2105 during monitoring can be increased.

[0047] The specific implementation method of this embodiment is: when positioning the hydrological monitoring component 2105, the waterproof electric telescopic rod 2201 is started by the controller 17, and the clamping block 2202 is pushed by the extension of the telescopic end of the waterproof electric telescopic rod 2201. The movement of the clamping block 2202 drives the anti-slip pad 2203 to be in close contact with the surface of the hydrological monitoring component 2105. The anti-slip pad 2203 is made of soft silicone material, which increases the friction between the clamping block 2202 and the hydrological monitoring component 2105, thereby realizing the positioning of the hydrological monitoring component 2105, greatly avoiding the shaking of the hydrological monitoring component 2105, and improving the accuracy of monitoring.

[0048] Example 3: Please refer to Figures 1-10 The present invention provides a technical solution: a marine winch based on hydrological and geological surveys. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0049] As a further limitation of the stabilizing mechanism 2 of the present invention, the surface of the telescopic end of the hydraulic rod 12 is fixedly connected to the second motor 2303. It should be noted that the top of the extension rod 2301 is fixedly connected to the surface of the positioning ring 2110, and the output shaft of the second motor 2303 is fixedly connected to the rotating roller 2304. The surface of the rotating roller 2304 is fixedly connected to two main ropes 2313. One end of the two main ropes 2313 is fixedly connected to the positioning block 2305. The bottom of the positioning block 2305 is fixedly connected to four secondary ropes 2306. One end of the four secondary ropes 2306 is commonly fixedly connected to a conical ring 2307. The inner cavity of the conical ring 2307 is provided with a counterweight cone 2308. The counterweight cone 2308 is connected to the outer connector. It is fixedly connected to the bottom of the hydrological monitoring component 2105, one side of the four counterweight bars 2302 is in contact with the inner side of the conical ring 2307, the surface of the telescopic end of the hydraulic rod 12 is fixedly connected to the guide rod 2314, and the surface of the cable 15 and the surface of the main rope 2313 are both slidingly connected to the inner wall of the guide rod 2314; by setting up the center of gravity adjustment unit 23, the rotating roller 2304 can be rotated by the second motor 2303 to tighten the main rope 2313, so that the secondary rope 2306 and the conical ring 2307 are moved upward, and the conical ring 2307 can make the counterweight bar 2302 and the counterweight cone 2308 move closer to the center, thereby improving the stability of the center of gravity of the hydrological monitoring component 2105 and reducing the shaking of the hydrological monitoring component 2105.

[0050] A sliding rod 2309 is fixedly connected to one side of the counterweight bar 2302, and a sliding hole 2310 is provided on the surface of the conical ring 2307. The surface of the sliding rod 2309 is slidably connected to the inner cavity of the sliding hole 2310; by setting the sliding rod 2309 and the sliding hole 2310 for use in conjunction, the sliding hole 2310 can guide the sliding rod 2309, thereby ensuring the stability of the sliding connection between the conical ring 2307 and the counterweight bar 2302.

[0051] The inner wall of the counterweight bar 2302 is rotatably connected to a rotating shaft 2311, and the surface of the rotating shaft 2311 is fixedly connected to the inner wall of the extension rod 2301. The surface of the rotating shaft 2311 is movably sleeved with a second torsion spring 2312, and one end of the second torsion spring 2312 is fixedly connected to the surface of the rotating shaft 2311, and the other end of the second torsion spring 2312 is fixedly connected to one side of the counterweight bar 2302; by setting the rotating shaft 2311 and the second torsion spring 2312, the rotation of the counterweight bar 2302 is achieved. When the conical ring 2307 is not added to restrain it, the second torsion spring 2312 drives the counterweight bar 2302 to flip outward. After the conical ring 2307 is put on, the reaction force of the second torsion spring 2312 makes the counterweight bar 2302 fit tightly against the conical ring 2307.

[0052] The specific implementation of this embodiment is as follows: during the initial installation, the conical ring 2307 and the counterweight bar 2302 are separated. After the positioning of the hydrological monitoring component 2105 is completed, the four sliding rods 2309 are sequentially inserted into the four sliding holes 2310 by rotating the counterweight bar 2302 to achieve the engagement of the conical ring 2307 with the counterweight bar 2302. When encountering shaking, the second motor 2303 is started by the controller 17, and the output shaft of the second motor 2303 rotates, driving the rotating roller 2304 to rotate, thereby winding the main rope 2313. The tightening of the main rope 2313 drives the positioning block 2305 to move upward, and the upward movement of the positioning block 2305 drives the secondary rope 2306 to move upward, and the upward movement of the secondary rope 2306 drives the conical ring 2307 to move upward. The upward movement of the conical ring 2307 is driven by the sliding The engagement of the rod 2309 with the sliding hole 2310 causes the four counterweight bars 2302 to flip toward the counterweight cone 2308. The counterweight bars 2302 are adjusted in rotation angle through the rotating shaft 2311 and the second torsion spring 2312 until the sliding rod 2309 contacts the lowest end of the sliding hole 2310. At this time, the four counterweight bars 2302 cooperate with the shape of the conical ring 2307 and flip to contact the surface of the counterweight cone 2308. The flipping of the counterweight bars 2302 increases the center of gravity mass of the counterweight cone 2308, and the contact between the counterweight bars 2302 and the counterweight cone 2308 ensures the stability of the counterweight cone 2308, thereby ensuring the stability of the center of gravity of the hydrological monitoring component 2105. As for the orderliness of the cable 15 when winding, there is now a mature structure that can achieve it, which will not be elaborated here.
