Description

Technical Field

[0001] The invention belongs to the technical field of cable retracting and releasing equipment, and in particular relates to a flexible cable arranging and releasing mechanism. Background Art

[0002] The towed temperature-salinity-depth profiler (UCTD) is an instrument that can quickly measure multiple parameters of seawater. Its operation process is to use a cable to tie the probe. When released, the probe falls freely in the seawater, and the drum wrapped with the cable rotates freely; after the probe falls to the predetermined depth, the winch brakes (the motor and the drum are usually connected by a clutch), and the drum stops rotating. After the detection is completed, the winch motor drives the drum to rotate in the opposite direction to retract the cable.

[0003] Affected by the impact of water flow and the drag of the survey ship, the stress condition of the cable is relatively complicated, causing the cables to be squeezed, entangled, and misaligned when they are recovered and wound on the drum. This leads to problems such as disordered cable arrangement after recovery and the cables piling up to form rope bundles, which seriously affects subsequent use.

[0004] Existing cable arrangement equipment, such as the underwater cable retracting and releasing mechanism disclosed in Chinese patent CN200610045772.2, can achieve regular cable arrangement. However, such equipment can only be applied to cables with high rigidity, such as steel wire ropes. The cables used in the UCTD system are made of synthetic fiber, with a small diameter and certain elasticity and compressibility. If such equipment is used, the taut cables will be squeezed into the gaps between the cables arranged on the drum, resulting in cable disorder and bulging of ropes.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0006] The technical problem solved by the present invention is the regular retraction and release of the flexible cable. When the cable is wound around the cable winding shaft, a high cable layer structure is formed on the longitudinal section of the receiving ring groove, so that the cable wound later will not be squeezed into the gap between the cables wound earlier, so that the regular discharge of the cable is achieved and the problems of disordered discharge and bulging of the cable are avoided.

[0007] In order to solve the above problems, the present invention provides a flexible cable arrangement mechanism, including a cable winding assembly; the cable winding assembly has a cable winding shaft; the cable winding shaft is fixedly sleeved with a first baffle plate and a second baffle plate; a plurality of accommodating annular grooves are sequentially formed along the axial direction of the cable winding shaft between the first baffle plate and the second baffle plate;

[0008] The width of each accommodating annular groove is equal to or slightly larger than the diameter of the cable. The cable is wound around the cable winding shaft, forming a structure in which the cable layers are stacked high on the longitudinal section of the accommodating annular groove.

[0009] According to the flexible cable evacuation mechanism of the present invention, a plurality of partition plates sleeved on the cable winding shaft are provided between the first baffle plate and the second baffle plate; the first baffle plate and the second baffle plate respectively form the accommodating annular groove with the closest partition plate and between two adjacent partition plates; the diameter of each partition plate is smaller than the diameter of the first baffle plate and the second baffle plate.

[0010] According to the flexible cable evacuation mechanism of the present invention, the periphery of the separation plate has an inclined surface facing the second baffle.

[0011] According to the flexible cable arranging mechanism of the present invention, the diameter of each partition plate decreases successively from the first baffle plate to the second baffle plate.

[0012] According to the flexible cable arranging mechanism of the present invention, the thickness of the separation plate is smaller than the width of the accommodating annular groove.

[0013] According to the flexible cable arranging mechanism of the present invention, the thickness of the separation plate is 1 / 2 of the width of the accommodating annular groove.

[0014] According to the flexible cable arranging mechanism of the present invention, the periphery of the separation plate is an arc-shaped transition structure.

[0015] The flexible cable arrangement mechanism according to the present invention also has a magnetic coupling for connecting the motor and the rope winding assembly;

[0016] The rope winding assembly includes an outer magnet connected to the motor shaft and an inner magnet connected to the cable winding shaft; the outer magnet is provided with an outer magnetic pole, and the inner magnet is provided with an inner magnetic pole opposite to the outer magnetic pole; an isolation cover is provided between the outer magnetic pole and the inner magnetic pole.

[0017] In summary, after the cable of the present invention is wound around the cable winding shaft, a structure in which the cable layers are stacked high is formed on the longitudinal section of the accommodating ring groove, and the situation in which the later wound cable is squeezed into the gaps between the earlier wound cables will not occur. Regular arrangement of the cables is achieved, and problems such as disordered arrangement and rope bulging are avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1 The present invention provides a flexible cable arrangement mechanism, including a cable winding assembly; the cable winding assembly has a cable winding shaft 11; the cable winding shaft 11 is fixedly sleeved with a first baffle plate 1 and a second baffle plate 2; a plurality of accommodating annular grooves 13 are sequentially formed along the axial direction of the cable winding shaft 11 between the first baffle plate 1 and the second baffle plate;

[0024] Combination Figure 2 The width of each receiving annular groove 13 is equal to or slightly larger than the diameter of the cable. As the cable winding shaft 11 rotates, the cable is wound on the cable winding shaft 11 and stacked up layer by layer in the receiving annular groove 13. That is, the cable is wound on the cable winding shaft 11, and a structure of stacked cables is formed on the longitudinal section of the receiving annular groove 13. Therefore, the situation that the cable wound later is squeezed into the gap between the cable wound earlier will not occur. When the cable is stacked on the top of the receiving annular groove 13, the cable automatically slides into the adjacent receiving annular groove 13.

[0025] The cable winding starts from the accommodating annular groove 13 closest to the first baffle 1, and is wound into each accommodating annular groove 13 in sequence along the cable winding shaft 11, thereby achieving regular discharge of the cable and avoiding problems such as disordered discharge and rope bulging.

[0026] As an embodiment, a plurality of partition plates 12 sleeved on the cable winding shaft 11 are provided between the first baffle plate 1 and the second baffle plate 2 ; the accommodating annular groove 13 is formed between the first baffle plate 1 and the second baffle plate 2 and the closest partition plates 12 as well as between two adjacent partition plates 12 .

[0027] More preferably, the periphery of the separation plate 12 has an inclined surface facing the second baffle 2 , and after the cable is stacked on the top of the accommodating annular groove 13 , it can smoothly slide into the next accommodating annular groove 13 along the inclined surface.

[0028] To prevent the cable from overflowing, the diameter of each separation plate 12 is smaller than the diameter of the first baffle plate 1 and the second baffle plate 2 .

[0029] Combination Figure 3 As an embodiment, the diameter of each partition plate 12 decreases from the first baffle plate 1 to the second baffle plate 2. When the cable is stacked on the top of the receiving annular groove 13, it automatically slides to the side of the partition plate 12 with a smaller diameter, thereby entering the adjacent receiving annular groove 13.

[0030] Better yet, the thickness of the separator plate 12 is smaller than the width of the accommodating annular groove 13; in the present invention, the thickness of the separator plate 12 is preferably 1 / 2 of the width of the accommodating annular groove 13; since the thickness of the separator plate 12 is significantly smaller than the diameter of the cable, the cable can smoothly slide into the next accommodating annular groove 13.

[0031] Furthermore, the periphery of the separation plate 12 is an arc-shaped transition structure, which enables the cable to slide smoothly.

[0032] The connection between the drum and the motor of the existing winch is in the form of a clutch. When the probe is in free fall, the winch drum needs to be in a free state so that the cable can be released freely. This requires the friction force on the drum to be as small as possible. However, due to the existence of the clutch, the winch drum and the motor shaft cannot be completely physically separated. In fact, the drum is still restricted by the motor and cannot be completely free, thus affecting the release of the cable. Moreover, the cable is subjected to a certain impact force when the brake is suddenly stopped, and there is a risk of being broken.

[0033] To address this problem, the flexible cable arrangement mechanism of the present invention also has a magnetic coupling for connecting the motor and the rope winding assembly;

[0034] See also Figure 4 The rope winding assembly includes an outer magnet 3 connected to the motor shaft 4 and an inner magnet 32 ​​connected to the cable winding shaft 11; the outer magnet 3 is provided with an outer magnetic pole 31, and the inner magnet 32 ​​is provided with an inner magnetic pole 33 opposite to the outer magnetic pole 31; an isolation cover 34 is provided between the outer magnetic pole 31 and the inner magnetic pole 33;

[0035] When the probe is released, the magnetic coupling is powered off and the rope assembly rotates freely; when braking, the magnetic coupling is powered on, and the force between the inner and outer magnets is controlled by controlling the magnitude of the current, thereby achieving flexible braking, reducing the impact force on the cable and avoiding breakage.

[0036] In summary, the present invention provides a flexible cable arranging mechanism. When the cable is wound around the cable winding shaft, a structure with high cable layers is formed on the longitudinal section of the accommodating ring groove. The situation in which the later wound cable is squeezed into the gaps of the earlier wound cables will not occur, thereby achieving regular cable arrangement and avoiding problems such as disordered arrangement and rope bulging.

[0037] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
