Description

Technical Field

[0001] The invention relates to a lifting device, in particular to a lifting device for intercepting a floating marine organism net, and belongs to the technical field of marine engineering. Background Art

[0002] When the plankton interception net is in use, the net sinks into the sea water, and the top of the net is limited by buoys to ensure that the net can form a barrier on the vertical plane. However, after a long period of use, plankton will accumulate on the surface of the net, causing the net to be blocked. The water-passing capacity of the net will gradually decrease, resulting in water not being able to pass normally. In this way, the net will not be able to effectively intercept subsequent plankton, thus losing its original function. When too much plankton accumulates on the net, it will also increase the weight of the net, which may cause the interception net to deform and be damaged. Therefore, the net needs to be cleaned regularly.

[0003] At present, in the process of cleaning the net, people take a cleaning boat to move along the length direction of the net, and use the winch system on the bracket to lift the net for cleaning. However, in the process of cleaning, the position of the hook and the lifting position need to be changed frequently, which seriously affects the cleaning rate. In addition, after the net is lifted, the weight on one side of the hull increases, affecting the stability of the hull.

[0004] Therefore, a lifting device for intercepting floating marine organisms is designed to optimize the above-mentioned problem. Summary of the invention

[0005] The main object of the present invention is to provide a lifting device for intercepting planktonic marine organisms net body.

During the process of lifting the net body, the rotation of the cylinder is actively controlled, and it is used in cooperation with the guide ring and the convex block on the side of the C-shaped plate. During the rotation of the cylinder, the active telescoping of the slide rod on the cylinder can be sequentially controlled, and the insertion position of the slide rod and the net body can be changed along the length direction of the net body, so that the device can move uniformly along the length direction of the net body, without reciprocally controlling the lifting of the net body and manually adjusting the position of the support point, which is more convenient to use and improves the cleaning rate of the net body. By providing a fixing mechanism composed of an inverted L-shaped plate, a first cross bar, a first positioning bolt, and a second cross bar on the rectangular bracket, when the device is in use, the bracket can be inserted and fixed on the guardrail on the side of the ship hull, which is more convenient for installation and use.

[0019] To make the technical solutions of the present invention clearer and more definite to those skilled in the art, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present invention are not limited thereto.

[0020] As Figure 1-Figure 8As shown in the figure, this embodiment provides a lifting device for intercepting planktonic marine organisms net body, including a rectangular bracket 1. The rectangular bracket 1 is vertically arranged on the side of the hull, and the bottom end of the rectangular bracket 1 is located below the sea level. A fixing mechanism 12 connected to the hull guardrail is provided at the bottom of the side of the rectangular bracket 1. A U-shaped plate 2 is vertically slidably arranged on the side of the rectangular bracket 1 away from the fixing mechanism 12. A rotating motor 3 is installed on the side of the U-shaped plate 2 close to the fixing mechanism 12. A guide ring 4 is fixed on the side of the U-shaped plate 2 away from the rotating motor 3. A convex block 5 is fixed on the outer side of the guide ring 4, and both ends of the convex block 5 are bevel edges. The output end of the rotating motor 3 passes through the U-shaped plate 2 and passes through the middle position of the guide ring 4. A first shaft rod 6 is installed at the output end of the rotating motor 3. A cylinder 7 is fixed at the end of the first shaft rod 6. Slide holes 8 are evenly arranged along the circumference of the cylinder 7. The slide holes 8 conduct both ends of the cylinder 7. Slide rods 9 are slidably installed inside the slide holes 8. First springs 10 are arranged between the ends of the slide holes 8 close to the U-shaped plate 2 and the slide rods 9. The slide rods 9 pass through the inside of the first springs 10 and extend to the outside of the cylinder 7. The ends of multiple groups of slide rods 9 are respectively in contact with the surfaces of the guide ring 4 and the convex block 5. Limit mechanisms 11 are arranged at the ends of the slide rods 9 away from the U-shaped plate 2. A stabilizing mechanism 13 is arranged at the middle position of the side of the rectangular bracket 1 away from the U-shaped plate 2. A lifting mechanism 14 for controlling the lifting of the U-shaped plate 2 and the flipping of the stabilizing mechanism 13 is arranged at the top of the rectangular bracket 1. A battery pack 15 is arranged outside the rectangular bracket 1.

[0021] Overall working principle: Before use, the device is installed on the guardrail on the side of the hull using the fixing mechanism 12. During use, it is powered by the battery pack 15. Using the lifting mechanism 14, the U-shaped plate 2 is moved downward. The slide rod 9 at the end of the cylinder 7 protrudes from the outer end of the cylinder 7 at the top position. The slide rod 9 at the top of the cylinder 7 is lowered below the sea level and inserted into the mesh holes of the net body. Then, the net body is lifted upward using the lifting mechanism 14. During the process of lifting the net body, the lifting mechanism 14 will control the deployment of the stabilizing mechanism 13 to adjust the center of gravity of the device to be close to the inside of the hull, ensuring the stability of the hull. After lifting the net body to the highest position, the net body is cleaned. The net body is conical, and the position supported by the slide rod 9 is at the highest point. The two sides of the net body corresponding to the position of the slide rod 9 on the side of the cylinder 7 are higher than the horizontal plane where the slide rod 9 is located. After partially cleaning the net body, the rotating motor 3 is started to drive the cylinder 7 to rotate. The height of the cylinder 7 is fixed. As the cylinder 7 rotates, the height of the net body will decrease to a certain extent. At this time, the slide rod 9 supporting the net body still contacts the horizontal end of the convex block 5, and the protruding length of the slide rod 9 remains unchanged. When the cylinder 7 rotates, the other slide rod 9 will slide along the surface of the convex block 5 and extend outward. When the cylinder 7 rotates to the top and the two slide rods 9 are at the same horizontal plane, at this time, the two slide rods 9 are simultaneously inserted into the inside of the net body. When the cylinder 7 is continuously controlled to rotate again, the slide rod 9 that previously supported the net body will lose the supporting effect on the net body until it slides off the convex block 5 and retracts into the slide hole 8 under the reset action of the first spring 10, while the net body is supported upward by the other slide rod 9 and returns to the highest position again. Repeating the above steps can continuously lift and clean the net body along the length direction of the net body. In addition, through the rotation of the rotating motor 3, not only can the contact point during the lifting of the net body be changed, but also a forward movement power can be applied to the hull, making it more convenient to use.

[0022] In this embodiment, the guide ring 4 and the convex block 5 are integrally formed, and arc chamfers are provided at the corners of the end of the convex block 5. One end of the slide rod 9 close to the guide ring 4 is arc-shaped.

[0023] Local working principle: During the rotation of the cylinder 7, the end of the slide rod 9 always slides along the outside of the guide ring 4 and the convex block 5. The arc chamfer at the end of the convex block 5 avoids the phenomenon of jamming, and the arc-shaped setting of the slide rod 9 can reduce the frictional resistance.

[0024] In this embodiment, the limiting mechanism 11 includes a collar 1101 and a second spring 1102. The collar 1101 is evenly sleeved on the end of the slide rod 9. The inner diameter of the collar 1101 is larger than the outer diameter of the slide rod 9, and second springs 1102 are evenly provided between the inner side of the collar 1101 and the outer side of the slide rod 9.

[0025] Local working principle: when the end of the sliding rod 9 extends out to support the net body, the net rope on the net body will contact the ring 1101, and pressure will be applied to the ring 1101. The ring 1101 at the contact part with the net rope will be concave, and the ring 1101 that is not squeezed will limit the net rope on the net body, thereby effectively preventing the net body from slipping and providing higher lifting stability for the net body.

[0026] In this embodiment, the fixing mechanism 12 includes an inverted L-shaped plate 1201, a first cross bar 1202 and a first positioning bolt 1203. The inverted L-shaped plate 1201 is symmetrically fixed on the side of the rectangular bracket 1. The first cross bar 1202 is fixed between the bottom ends of the two groups of inverted L-shaped plates 1201. The top end of the outer side of the inverted L-shaped plate 1201 is threadedly installed with a first positioning bolt 1203.

[0027] Local working principle: When installing and using the device, lift the device vertically to the top of the hull guardrail, align the inverted L-shaped plate 1201 and the rectangular bracket 1 with the guardrail, then move the rectangular bracket 1 vertically downward, the inverted L-shaped plate 1201 is stuck on the guardrail, and tighten the first positioning bolt 1203 to reinforce the position of the device.

[0028] In this embodiment, a second cross bar 1204 is provided between the tops of the inner sides of the two sets of inverted L-shaped plates 1201, the ends of the first positioning bolts 1203 are rotatably connected to the ends of the second cross bar 1204, and an arc groove is provided on one side of the second cross bar 1204 close to the rectangular bracket 1.

[0029] Partial working principle: Tightening of the first positioning bolt 1203 will control the second cross bar 1204 to move toward the guardrail and fit with the guardrail, thereby increasing the contact area with the guardrail and improving the stability of the fixation.

[0030] In this embodiment, the stabilizing mechanism 13 includes a rotating rod 1301, a support rod 1302, a third cross rod 1303 and a counterweight 1304. The rotating rod 1301 is rotatably installed at the middle position of the rectangular bracket 1. Support rods 1302 are fixed at both ends of the rotating rod 1301. A third cross rod 1303 is fixed between the two groups of support rods 1302. A counterweight 1304 is slidably arranged between the ends of the two groups of support rods 1302, and the battery pack 15 is fixed on the surface of the counterweight 1304.

[0031] Local working principle: After the net is lifted, the rotating rod 1301 will be controlled to rotate in the direction away from the rectangular bracket 1, and the counterweight block 1304 on the support rod 1302 will swing toward the inside of the hull, placing the center of gravity of the device inside the hull to ensure the stability of the hull. In addition, the battery pack 15 has a large weight, and the effect is better when used with the counterweight block 1304.

[0032] In this embodiment, chutes 1305 adapted to cooperate with the support rods 1302 are symmetrically formed at the ends of the counterweight 1304. The ends of the support rods 1302 are located inside the chutes 1305. Second positioning bolts 1306 are threadedly installed on both sides of the counterweight 1304, and the ends of the second positioning bolts 1306 extend into the chutes 1305 and contact the surfaces of the support rods 1302.

[0033] Local working principle: If the weight of the net body is large, the counterweight 1304 can be controlled to slide along the length direction of the support rod 1302, and the counterweight 1304 is moved away from the rectangular bracket 1 to ensure the stability of the hull.

[0034] In this embodiment, a buckle groove is formed at one end of the counterweight 1304 away from the support rod 1302.

[0035] Local working principle: When moving the position of the counterweight 1304, the buckle groove can be used to facilitate pulling the counterweight 1304.

[0036] In this embodiment, the lifting mechanism 14 includes a mounting plate 1401, a lifting motor 1402, a second shaft 1403, sprockets 1404, a chain 1405, and a through opening 1406. The mounting plate 1401 is fixed to the top of the rectangular bracket 1. A lifting motor 1402 is installed at one end of the mounting plate 1401. The output end of the lifting motor 1402 is installed with a second shaft 1403. Sprockets 1404 are fixed to both ends of the second shaft 1403. Chains 1405 are provided on the sprockets 1404. A through opening 1406 adapted to cooperate with the chain 1405 is formed on the mounting plate 1401. One end at the bottom of the sprocket 1404 is fixedly connected to the top of the U-shaped plate 2, and the other end of the sprocket 1404 is fixedly connected to the third cross bar 1303.

[0037] Local working principle: When the U-shaped plate 2 is at the lowermost position of the rectangular bracket 1 and the counterweight 1304 is in contact with the surface of the rectangular bracket 1, when controlling the U-shaped plate 2 to rise and the counterweight 1304 to expand outward, the lifting motor 1402 is started to drive the two groups of sprockets 1404 on the second shaft 1403 to rotate. One end of the chain 1405 rises while the other end descends. When the U-shaped plate 2 rises, the counterweight 1304 will automatically expand outward and be controlled synchronously.

[0038] In this embodiment, a protective cover 1407 is fixed to the top of the mounting plate 1401. A brush rod 1408 is fixed between the two ends inside the protective cover 1407. The outer side of the brush rod 1408 is in contact with the surface of the chain 1405.

[0039] Local working principle: When the chain 1405 moves, it will slide along the outer side of the brush rod 1408, and the brush rod 1408 automatically cleans the chain 1405.
