Technical Field
[0001] This utility model belongs to the technical field of hydrological monitoring equipment, specifically relating to a hand-cranked winch for marine environmental monitoring. Background Technology
[0002] Hydrological winches are used for hydrological surveys and underwater scientific research activities. Specifically, they carry various instruments and equipment to a certain depth underwater to collect data such as flow velocity, flow direction, water temperature, water depth, salinity, and sediment content. The instruments and equipment include hydrological survey instruments and water sampling equipment.
[0003] A prior art patent, CN218403448U, describes a hand-cranked winch. This patent includes a base, a winch disc, a first rotating shaft, and a second rotating shaft. Both the first and second rotating shafts are directly or indirectly rotatably mounted on the base. The winch disc is mounted on the first rotating shaft. The winch also includes a bushing, a handle, an adjusting block, and a locking nut. The bushing is mounted on the second rotating shaft, and the adjusting block is located on the bushing. The adjusting block has a sliding groove, and the handle slides into the groove on the adjusting block. The locking nut is located on the adjusting block and is used to lock the handle. The handle's position is adjustable, allowing operators to adjust it according to their needs, making it easier and more convenient to use. However, in practical use, it still has the following shortcomings: From a practical standpoint, when placing instruments and equipment, it is not convenient to use a hand crank for stable placement, reducing placement efficiency. The hand cranking process cannot quickly place instruments and equipment, thus reducing the device's practicality.
[0004] Therefore, a hand-cranked winch for marine environmental monitoring is needed to solve the problem of the inconvenience of quickly and conveniently placing and using instruments and equipment in existing technologies. Utility Model Content
[0005] The purpose of this invention is to provide a hand-cranked winch for marine environmental monitoring to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine environmental monitoring hydrological hand-cranked winch, comprising a base, a mounting base, and a cantilever. The mounting base is rotatably mounted on the top of the base, and the cantilever is fixedly mounted on the left side of the mounting base. A fixed pulley is rotatably mounted on the top of the cantilever, and a cable is provided on the fixed pulley. A winch is provided at the other end of the cable, and the winch is rotatably mounted on the mounting base. A hand-cranking mechanism is provided on the mounting base, and the winch is rotatably mounted on the mounting base via the hand-cranking mechanism.
[0007] The hand-crank mechanism is equipped with a positioning component, which is used to cooperate with the hand-crank mechanism to rotate the winch.
[0008] The solution specifies that the hand-cranked mechanism includes a base plate fixedly connected to the upper part of the mounting base.

[0022] The present invention will be further described below with reference to the embodiments.
[0023] Please see Figure 1-4 This utility model provides a marine environmental monitoring hydrological hand-cranked winch, including a base 1, a mounting base 2, and a cantilever 3. The mounting base 2 is rotatably mounted on the top of the base 1, and the cantilever 3 is fixedly mounted on the left side of the mounting base 2. A fixed pulley 4 is rotatably mounted on the top of the cantilever 3, and a cable 5 is provided on the fixed pulley 4. A winch 6 is provided at the other end of the cable 5. The winch 6 is rotatably mounted on the mounting base 2, and a hand-cranking mechanism 7 is provided on the mounting base 2. The winch 6 is rotatably mounted on the mounting base 2 through the hand-cranking mechanism 7.
[0024] The hand crank mechanism 7 is equipped with a positioning component 71, which is used to cooperate with the hand crank mechanism 7 to rotate the winch 6.
[0025] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the hand-cranked mechanism 7 includes a base plate 701, which is fixedly connected to the upper part of the mounting base 2. Support plates 702 are fixedly connected to the front and rear sides of the base plate 701. A rotating shaft 703 is rotatably mounted on the front support plate 702, and the rotating shaft 703 is rotatably mounted on the mounting base 2. A rocker arm 704 is fixedly connected to the front end of the rotating shaft 703, and a first disc gear 705 is fixedly connected to the rear end of the rotating shaft 703. A connecting gear 706 is meshed at the bottom rear side of the first disc gear 705, and the connecting gear 706 is rotatably mounted on the base plate 701. A second disc gear 707 is meshed at the rear side of the connecting gear 706, and a connecting cylinder 708 is fixedly connected to the rear side of the second disc gear 707. The connecting cylinder 708 is rotatably mounted on the rear support plate 702. Gear 707 is rotatably mounted on support plate 702 via connecting cylinder 708. Drive shaft 709 is rotatably mounted inside connecting cylinder 708 and mounted on mounting base 2. Ratchet 7010 is fixedly connected to drive shaft 709. Positioning rod 7011 is fixedly connected to the front end of drive shaft 709. Positioning rod 7011 has a matching positioning groove 7014 on the rear surface of the first disc gear 705. Drive gear 7012 is fixedly connected to the rear end of drive shaft 709. Driven gear 7013 is meshed on the left side of drive gear 7012. Driven gear 7013 is fixedly connected to the rear end of winch 6. Two ratchet 7010s are mounted on drive shaft 709, and the two ratchet 7010s are respectively positioned close to the first disc gear 705 and the second disc gear 707.
[0026] In use, when the rocker arm 704 rotates counterclockwise, the positioning block 712 on the first disc gear 705 presses against the ratchet 7010, thereby causing the positioning block 712 to press against the spring 713. This allows the first disc gear 705 to rotate outside the ratchet 7010. At this time, the first disc gear 705 drives the connecting gear 706 to rotate, which in turn causes the second disc gear 707 to rotate. The rotation of the second disc gear 707 causes the positioning component 71 on the second disc gear 707 to limit the ratchet 7010. This causes the second disc gear 707 to rotate, driving the ratchet 7010 and the drive shaft 709 to rotate inside the connecting cylinder 708. This causes the driving gear 7012 to rotate, driving the driven gear 7013 to rotate, thereby causing the winch 6 to rotate and release the cable 5, thus realizing the placement of the instrument and equipment.
[0027] When the rocker arm 704 is rotated clockwise, the positioning component 71 on the first disc gear 705 limits the ratchet 7010, which drives the drive shaft 709 to rotate. This causes the drive gear 7012 to drive the driven gear 7013 to rotate, thereby causing the winch 6 to continuously release the cable. Through the above operations, the winch 6 will rotate to release the cable 5 regardless of which direction it is rotated, thus improving the placement efficiency of the instrument and equipment.
[0028] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the positioning components 71 are respectively set on the first disc gear 705 and the second disc gear 707. The two positioning components 71 are centrally symmetrically arranged on the first disc gear 705 and the second disc gear 707. The positioning component 71 includes a fixing frame 711, which is fixedly connected to the first disc gear 705 or the second disc gear 707. A positioning block 712 is slidably arranged inside the fixing frame 711. A spring 713 is fixedly installed on one side of the positioning block 712 inside the fixing frame 711. The positioning block 712 is matched with the ratchet teeth of the ratchet 7010.
[0029] This solution has the following working process: When this device is in use, the entire device is positioned and installed using the base 1. The instrument is connected to the end of the cable 5, and the instrument is placed in the ocean for use by rotating the mounting base 2. At this time, by rotating the rocker arm 704, the rotating shaft 703 rotates on the support plate 702, thereby driving the first disc gear 705 to rotate through the rotating shaft 703. The positioning component 71 is set on the first disc gear 705. When the rocker arm 704 rotates counterclockwise, the positioning block 712 on the first disc gear 705 presses against the ratchet 7010, thereby causing the positioning block 712 to compress the spring 713, so that the first disc gear 705 can rotate outside the ratchet 7010. At this time, the first disc gear 705 drives the connecting gear 706 to rotate, which in turn causes the second disc gear 707 to rotate. The rotation of the second gear 707 causes the positioning component 71 on the second gear 707 to limit the ratchet 7010, thereby causing the second gear 707 to rotate and drive the ratchet 7010 and drive shaft 709 to rotate within the connecting cylinder 708. This, in turn, causes the drive gear 7012 to rotate and drive the driven gear 7013 to rotate, thus causing the winch 6 to rotate and release the cable 5, enabling the placement of the instrument. When the rocker arm 704 is rotated clockwise, the positioning component 71 on the first gear 705 limits the ratchet 7010, which drives the drive shaft 709 to rotate. This, in turn, causes the drive gear 7012 to drive the driven gear 7013 to rotate, thus causing the winch 6 to continuously release the cable. Through the above operations, the winch 6 will rotate and release the cable 5 regardless of the direction of rotation, thereby improving the placement efficiency of the instrument.
[0030] In summary: By using the hand crank mechanism 7, the winch 6 can be rotated by turning the rocker arm 704. During this process, the winch 6 can always be unloaded in the direction of the rocker arm 704, thereby improving the efficiency of placing and using the equipment. Furthermore, the equipment can be locked at any time during placement to effectively prevent it from falling quickly, thus improving the practicality of the device.
