Description

Technical Field

[0001] The invention relates to the technical field of marine scientific exploration equipment, and in particular to a cable climbing device driven by wave energy. Background Art

[0002] In marine scientific research, it is often necessary to conduct scientific observations on the vertical surface of the ocean, that is, to observe the various water layers on the profile of the ocean from top to bottom, and observe the hydrological parameters and hydrological phenomena of each water layer at different heights. If observation equipment is set up at different heights, it is obviously costly and unnecessary. If manual or electric-driven lifting observation equipment is used, manual supervision is required, or the battery needs to be replaced frequently because it consumes a lot of electricity to drive the observation equipment up and down. Summary of the invention

[0003] The present invention is aimed at equipment that needs to be placed underwater to observe the vertical profile of the ocean, and provides a cable climbing device with a simple structure, which can be driven by wave energy to complete climbing and can be automatically raised and lowered.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A wave energy driven cable climbing device comprises a buoy and a cable connected to the bottom of the buoy. The cable is provided with an upper baffle, a lower baffle and an automatic lifting device located between the upper baffle and the lower baffle. The automatic lifting device comprises two panels connected to each other. A lifting space is provided between the two panels. The cable passes through the lifting space. A one-way cable clamping device fixed to the panel and a reversing device linked to the one-way cable clamping device are also provided in the lifting space. The reversing device comprises a reversing rod with both ends extending out of the panel range. The reversing rod is arranged in cooperation with the upper baffle and the lower baffle. Observation equipment is respectively provided on the two panels.

[0006] Preferably, the one-way cable clamping device of the automatic lifting device includes two groups of climbing hands, and the two groups of climbing hands are respectively provided with left-turning hooks and right-turning hooks located on both sides of the cable, and the left-turning hooks and right-turning hooks are rotatably connected to the panel through pins and torsion springs, and the left-turning hooks and right-turning hooks are L-shaped, and the reversing rod of the reversing device is provided with left reversing rods and right reversing rods, and the left reversing rods are linked with the left-turning hooks of the two groups of climbing hands, and the right reversing rods are linked with the right-turning hooks of the two groups of climbing hands. In this scheme, there are torsion springs on the climbing hands, but the force is not strong, which is used to reset the climbing hands instead of clamping the cable. If the cable moves upward, it will drive the climbing hands to rotate upward, and the climbing hands just clamp the cable; in addition, when the cable moves downward, the reason why the device does not move with the cable is that the cable rises and falls quickly, and the device has only a slight negative buoyancy, so the cable will move downward relative to the device.

[0007] Preferably, the reversing device comprises a tension spring, a guide shaft fixed on the panel, and a tension spring fixing column. The reversing rod is provided with a reversing block, a tension spring pin column, and a long hole matched with the guide shaft. The reversing block is matched with the left rotating hook and the right rotating hook of the one-way cable clamping device. The two ends of the tension spring are respectively connected with the tension spring fixing column and the tension spring pin column. The tension spring in this scheme plays the role of positioning the reversing rod. It can ensure that the reversing rod will move only after it touches the upper and lower baffles, and the reversing rod will not move during other lifting processes.

[0008] Preferably, the left and right rotating hooks of the two groups of climbing hands are provided with chamfered surfaces on the sides close to the cables, and the chamfered surfaces are in contact with the cables. The chamfered surfaces of this solution ensure that the left and right rotating hooks are in surface contact with the cables, ensuring that the cables will not slide when they are stuck.

[0009] Preferably, the contact points between the left-turning hook and the right-turning hook and the cable are inclined toward the bottom of the cable, and the automatic lifting device is a negative buoyancy device.

[0010] Preferably, the contact points between the left-turning hook and the right-turning hook and the cable are inclined toward the top of the cable, and the automatic lifting device is a positive buoyancy device.

[0011] When the one-way cable clamping device of this scheme is installed properly, the automatic lifting device is set to have a slight negative buoyancy. The adjustment block installed on the reversing frame will not interfere with the one-way climbing hand. The automatic lifting device will climb up along the rope step by step. When it climbs to the top of the cable, the reversing frame hits the baffle and switches position. At this time, the adjustment block installed on the reversing frame will interfere with the one-way climbing hand, open the one-way climbing hand, and the one-way climbing hand will fail. The automatic lifting device moves downward along the rope due to negative buoyancy. After moving to the bottom of the cable, the reversing frame hits the baffle and switches to the other side. The one-way climbing hand is no longer interfered with, and the automatic lifting device begins to climb up along the rope step by step. The main power of this scheme is the waves. The waves drive the buoy up and down, and the buoy drives the cable up and down. When the cable moves downward, the one-way climbing hand can also rotate downward, and the cable can move downward through the one-way climbing hand. When the cable moves upward, the one-way climbing hand cannot rotate upward, so the cable cannot pass through the one-way climbing hand. At this time, the performance of the entire automatic lifting device is that it will move upward with the cable.

[0012] When the one-way cable clamping device of this scheme is reversed, the automatic lifting device is adjusted to have a slightly positive buoyancy. The lifting principle of the automatic lifting device is opposite to that when the device is installed upright, and the automatic lifting device can also be realized to reciprocate along the cable.

[0013] Compared with the prior art, the beneficial effects of the present invention are: it is easy to retract and can solve the problem of automatic lifting of the device when observing the vertical profile of the ocean, and the use of wave energy to drive the device is better than the automatic lifting of the electric energy drive device, which greatly reduces the battery consumption.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , the present invention provides a technical solution:

[0023] A wave energy driven cable climbing device, comprising a buoy 1, a cable 2 connected to the bottom of the buoy 1, an upper baffle 3, a lower baffle 4, and an automatic lifting device 5 located between the upper baffle 3 and the lower baffle 4, the automatic lifting device 5 comprising two panels 6 connected to each other, a lifting space being provided between the two panels 6, the cable 2 passing through the lifting space, a one-way cable clamping device fixed on the panel 6, and a reversing device linked to the one-way cable clamping device being provided in the lifting space, the reversing device comprising a reversing rod 7 with both ends extending out of the range of the panel 6, the reversing rod 7 being provided in cooperation with the upper baffle 3 and the lower baffle 4, and observation equipment being provided on the two panels 6 respectively;

[0024] The one-way cable clamping device of the automatic lifting device 5 includes two groups of climbing hands, and the two groups of climbing hands are respectively provided with a left rotating hook 8 and a right rotating hook 9 located on both sides of the cable 2. The left rotating hook 8 and the right rotating hook 9 are rotatably connected to the panel 6 through a pin shaft and a torsion spring, respectively. The left rotating hook 8 and the right rotating hook 9 are L-shaped. The reversing rod 7 of the reversing device is provided with a left reversing rod and a right reversing rod. The left reversing rod is linked to the left rotating hook 8 of the two groups of climbing hands, and the right reversing rod is linked to the right rotating hook 9 of the two groups of climbing hands;

[0025] The reversing device includes a tension spring 10, a guide shaft fixed on the panel 6, and a tension spring fixing column. The reversing rod 7 is provided with a reversing block 11, a tension spring pin column, and a long hole matched with the guide shaft. The reversing block 11 is matched with the left rotating hook 8 and the right rotating hook 9 of the one-way cable clamping device. The two ends of the tension spring are respectively connected with the tension spring fixing column and the tension spring pin column;

[0026] The left rotating hook 8 and the right rotating hook 9 of the two sets of climbing hands are provided with chamfered surfaces on the sides close to the cable 2, and the chamfered surfaces are in contact with the cable 2;

[0027] The contact points between the left rotating hook 8 and the right rotating hook 9 and the cable 2 are inclined toward the bottom of the cable 2, that is, the one-way cable clamping device is installed upright, and the automatic lifting device 5 is a negative buoyancy device.

[0028] In addition, the contact points between the left rotating hook 8 and the right rotating hook 9 and the cable 2 are inclined toward the top of the cable, that is, the one-way cable clamping device is reversely installed, and the automatic lifting device 5 is a positive buoyancy device.

[0029] The specific use process is: when the one-way cable clamping device is installed properly, the waves drive the buoy 1 up and down, and the buoy 1 drives the cable 2 up and down. When the cable 2 moves downward with the buoy 1, the one-way climbing hand can also rotate downward, and the cable 2 can move downward through the one-way climbing hand. When the cable 2 moves upward with the buoy 1, the one-way climbing hand cannot rotate upward, so the cable 2 cannot pass through the one-way climbing hand. At this time, the performance of the entire automatic lifting device 5 is that it moves upward with the cable 2; after the automatic lifting device 5 rises to the reversing rod 7 and contacts the upper baffle 3, it is blocked by the upper baffle 3. The block moves downward, the reversing block 11 drives the left rotating hook 8 and the right rotating hook 9 to rotate downward, and then the reversing rod 7 is positioned under the action of the tension spring 10. When the entire automatic lifting device 5 is negatively buoyant and the left rotating hook 8 and the right rotating hook 9 no longer clamp the cable 2, the automatic lifting device 5 sinks until the reversing rod 7 contacts the lower baffle 4 and then moves upward, the reversing block 11 drives the left rotating hook 8 and the right rotating hook 9 to rotate upward, and then the reversing rod 7 is positioned under the action of the tension spring 10, the left rotating hook 8 and the right rotating hook 9 clamp the cable 2 again, and the entire automatic lifting device 5 restarts the cable climbing process.

[0030] In addition, when the one-way cable clamping device is installed upright, the automatic lifting device 5 is a positive buoyancy device, and its lifting principle is opposite to that when the one-way cable clamping device is installed upright, and the automatic lifting device 5 can also achieve reciprocating motion along the cable 2.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
