Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting platform technology, and specifically relates to a net clothing lifting system. Background Technology
[0002] Traditional platform systems, such as ballast tanks and pontoon systems, may suffer from slow response, complex structure, and difficult maintenance. While winch systems only raise and lower the netting, the platform itself is unstable, and the ropes are prone to wear. Therefore, existing technologies typically employ four-point lifting systems (especially winch-traction systems). During lifting, due to ocean current impacts, uneven loads, or asynchronous motors, inconsistent lifting heights at the four corners of the platform are highly likely. Furthermore, the separate design of the traction mechanism, support structure, and limiting structure results in insufficient structural rigidity and unclear force transmission paths, leading to unstable lifting paths, increased structural stress and wear, and a high risk of platform tilting or even capsizing. To address these issues, we propose a photovoltaic energy storage system for the netting lifting system. Utility Model Content
[0003] This invention provides a mesh garment lifting system to solve the problems mentioned in the background art.
[0004] This utility model provides the following technical solution: a netting lifting system, including a netting rack end face, with traction execution modules provided at the four corners of the netting rack end face, and traction limiting guide rails, transmission end connecting units and opposing limiting pillars provided inside the traction execution modules. The traction limiting guide rails are used to slide and limit the traction execution modules when they are vertically lifted and lowered. The netting rack support module is connected to the aquaculture platform.
[0005] The transmission end connection unit is connected to the platform traction end and is used to provide the transmission power when the traction execution module is vertically raised and lowered.
[0006] The opposing limiting support is equipped with a lifting execution point processing unit, which is arranged in the same direction at equal intervals. The opposing limiting support is symmetrically arranged with the traction limiting guide rail. The opposing limiting support is used to assist the traction execution module in vertical lifting limit. The lifting execution point processing unit is used to determine the current vertical lifting height of the platform based on the sliding adjustment position of the directional roller transmission component.
[0007] A further improvement of this utility model is that the traction execution module includes a directional roller transmission component, a linkage slot seat, and a central shaft transmission pin component. The linkage slot seat is fixedly connected to the net clothes rack support module, the directional roller transmission component is fixedly connected to the central shaft transmission pin component, and the central shaft transmission pin component is rotatably connected to the linkage slot seat.
[0008] A further improvement of this utility model is that both sides of the directional roller transmission component are provided with fitting guide cavities that fit into the traction limiting guide rail and the opposing limiting support column. The fitting guide cavities are used to trigger the receiving signal of the lifting execution point processing unit.
[0009] A further improvement of this utility model is that the transmission end connection unit includes a transmission sleeve rope and an end face external hanging buckle. The end face external hanging buckle is fixedly connected to the platform traction end, and the transmission sleeve rope is sleeved on the outside of the directional roller transmission component.
[0010] A further improvement of this utility model is that the lifting execution point processing unit is signal-connected to an external control terminal, and the lifting execution point processing unit is provided with a number of sensing contacts, which are arranged in an arc-shaped, equally spaced array.
[0011] A further improvement of this utility model is that an extension end adjustment bracket is fixedly connected to one end of the mesh clothes rack support module, a mesh clothes support hanging ring is fixedly connected to one end of the extension end adjustment bracket, and a nylon reinforcing rope is tied between the mesh clothes support hanging ring and the end face of the mesh clothes rack.
[0012] A further improvement of this utility model is that the method of using the aforementioned mesh garment lifting system includes the following steps:
[0013] Step S1: The drive system sends an execution signal to the platform traction end, and the platform traction end synchronously pulls the directional roller transmission component with the traction transmission rope, and drives the platform to perform longitudinal lifting and lowering through the net frame support module.
[0014] Step S2: Under traction conditions, the traction limiting guide rail and the opposing limiting support column limit the movement direction of the traction execution module, so that the net clothes rack support module can stably reach the vertical lifting path, change the lifting height of the net clothes rack support module, and realize the platform lifting operation.
[0015] Step S3: During the lifting and lowering operation of the platform driven by the mesh rack support module, the lifting execution point processing unit, which is arranged at the longitudinal position of the opposing limiting support column, measures the overall lifting height of the directional roller transmission component. That is, the lifting execution point processing unit measures the trigger signal of the directional roller transmission component along the arc-shaped arrangement surface, determines whether the deviation of its signal response parameter exceeds the set threshold, and sends a switching signal to the platform traction end through the lifting execution point processing unit according to the parameter exceeding the threshold. The platform traction end then makes a longitudinal fine adjustment to the position of the directional roller transmission component, that is, further corrects the height of the four sets of mesh rack support modules, so that the platform maintains stability in a horizontal state.
[0016] Compared with existing technologies, this invention utilizes a lifting execution point processing unit arranged at equal intervals on the opposing limiting pillars and its arc-shaped array of sensing contacts to detect the precise height position of the directional roller transmission components in real time. Specifically, when the height signal deviation at the four corners exceeds a set threshold, the system automatically sends a switching signal to the platform traction end to finely adjust the position of the corresponding directional roller transmission components longitudinally. This achieves dynamic synchronous correction of the platform's four corner heights, significantly improving the platform's horizontal stability during lifting and when stationary, and reducing the risk of tilting. Simultaneously, the symmetrical arrangement of the traction limiting guide rail and the opposing limiting pillars forms a rigid track, allowing the directional roller transmission components to have fitting guide cavities on both sides that are strictly fitted with the pillars. This forces them to slide only in the vertical direction, greatly limiting the horizontal degree of freedom and ensuring that the lifting process strictly follows the vertical path, reducing swaying and deviation, and improving the overall stability after lifting and adjusting.

Detailed Implementation
[0020] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-2A netting lifting system includes a netting frame end face 1, with traction execution modules 2 at each of the four corners of the netting frame end face 1. The traction execution modules 2 are equipped with traction limiting guide rails 3, transmission end connecting units 4, and opposing limiting pillars 5 on their inner sides. The traction limiting guide rails 3 are used to slide and limit the traction execution modules 2 when they are vertically raised and lowered. The netting frame support module 6 is connected to the aquaculture platform.
[0022] In this embodiment, to address the problems of existing four-point lifting systems where inconsistent lifting heights at the four corners of the platform are easily caused by ocean current impact, uneven load, or asynchronous motors during the lifting process, and where the separate design of the traction mechanism, support structure, and limiting structure results in insufficient structural rigidity and unclear force transmission paths, leading to unstable lifting paths, increased structural stress and wear, and a risk of platform tilting or even overturning, this utility model proposes a netting lifting system. By setting up a traction execution module 2, a traction limiting guide rail 3, a transmission end connection unit 4, opposing limiting pillars 5, and a netting rack support module 6, dynamic synchronous correction of the height at the four corners of the platform is achieved, significantly improving the horizontal stability of the platform during lifting and when stationary. At the same time, the horizontal degree of freedom is restricted, ensuring that the lifting process strictly follows the vertical path, reducing swaying and deviation, and improving the overall stability after lifting and debugging.
[0023] In this embodiment, the transmission end connection unit 4 is connected to the platform traction end and is used to provide the transmission power when the traction execution module 2 is vertically raised and lowered.
[0024] In this embodiment, the opposing limiting pillar 5 is equipped with a lifting execution point processing unit 51. The lifting execution point processing unit 51 is arranged in the same direction with equal spacing. The opposing limiting pillar 5 is symmetrically arranged with the traction limiting guide rail 3. The opposing limiting pillar 5 is used to assist the vertical lifting limit of the traction execution module 2. The lifting execution point processing unit 51 is used to determine the current vertical lifting height of the platform according to the sliding adjustment position of the directional roller transmission component 21.
[0025] In this embodiment, due to the impact of ocean currents, uneven load, or asynchronous motors during the lifting process, the traditional four-point lifting system is prone to inconsistent lifting heights at the four corners of the platform, which may lead to the risk of platform tilting or even overturning. This utility model uses lifting execution point processing units 51 arranged at equal intervals on the opposing limiting support columns 5 to detect the precise height position of the directional roller transmission component 21 in real time. When the deviation of the four corner height signals exceeds the set threshold, the system automatically sends a switching signal to the platform traction end to finely adjust the position of the corresponding directional roller transmission component in the longitudinal direction, thereby achieving dynamic synchronous correction of the height of the four corners of the platform.
[0026] In this embodiment, the traditional winch / sweeper lifting system relies on rope traction. Under the action of wind, waves and currents, the net or platform is prone to swaying, rotating or deviating, resulting in unstable lifting path, increased structural stress and wear. To solve the above technical problems, this solution forms a rigid track by symmetrically arranging the traction limiting guide rail 3 and the opposing limiting support column 5, which completes the rigid vertical guidance of 21. The directional roller transmission component 21 is provided with fitting guide cavities 24 on both sides that are strictly fitted with the support column, which forcibly restricts it to slide only in the vertical direction, ensuring that the lifting process is strictly carried out along the vertical path and reducing swaying and deviation.
[0027] In this embodiment, the traction execution module 2 includes a directional roller transmission component 21, a linkage slot seat 22, and a central shaft transmission pin 23. The linkage slot seat 22 is fixedly connected to the net clothes rack support module 6, the directional roller transmission component 21 is fixedly connected to the central shaft transmission pin 23, and the central shaft transmission pin 23 is rotatably connected to the linkage slot seat 22.
[0028] In this embodiment, both sides of the directional roller transmission component 21 are provided with fitting guide cavities 24 that fit into the traction limiting guide rail 3 and the opposing limiting support column 5. The fitting guide cavities 24 are used to trigger the receiving signal of the lifting execution point processing unit 51.
[0029] In this embodiment, the drive system sends an execution signal to the platform traction end, and the platform traction end synchronously pulls the directional roller transmission component 21 with the traction transmission sleeve rope 41 to lift it. The platform is then driven to perform longitudinal lifting and lowering through the net frame support module 6. Compared with the separate design of the traction mechanism, support structure and limiting device in the prior art, this utility model highly integrates the traction directional roller transmission component 21, the limiting fitting guide cavity 24, the support connecting net frame support module 6 and the power transmission transmission end connecting unit 4 on the traction execution module 2. The linkage slot seat 22 is fixedly connected to the net frame support module 6, and the directional roller transmission component 21 is fixedly connected to the central shaft transmission pin 23 to form a stable force transmission chain, improve the overall structural rigidity and force transmission efficiency, and reduce deformation and failure caused by structural looseness.
[0030] In this embodiment, the transmission end connection unit 4 includes a transmission sleeve rope 41 and an end face external hanging buckle 42. The end face external hanging buckle 42 is fixedly connected to the platform traction end, and the transmission sleeve rope 41 is sleeved on the outside of the directional roller transmission component 21.
[0031] In this embodiment, the lifting execution point processing unit 51 is signal-connected to an external control terminal. The lifting execution point processing unit 51 is equipped with several sensing contacts, which are arranged in an arc-shaped, equally spaced array. The lifting execution point processing unit 51 is arranged in the same direction with equal spacing along the longitudinal direction of the support column, forming a high-density detection array. By triggering or approaching these arc-shaped sensing contacts through the fitting guide cavity 24 on the directional roller transmission component 21, its physical position is directly measured, providing multi-point, direct, and high-precision height position feedback, thus providing a reliable data foundation for levelness control.
[0032] In this embodiment, an extension end adjustment bracket 61 is fixedly connected to one end of the mesh hanger support module 6, and a mesh support hanging ring 62 is fixedly connected to one end of the extension end adjustment bracket 61. A nylon reinforcing rope is tied between the mesh support hanging ring 62 and the end face 1 of the mesh hanger. The mesh support hanging ring 62 extends from the end of the mesh hanger support module 6 and is fixed to the end face 1 of the mesh hanger by the nylon reinforcing rope. This serves to suspend and maintain the tension of the mesh system, ensuring the stability of the mesh shape and its synchronous lifting and lowering with the platform.
[0033] The working principle of this utility model is as follows: the drive system sends an execution signal to the platform traction end, and the platform traction end synchronously pulls and lifts the directional roller transmission component 21 by the traction transmission rope 41. The net clothes rack support module 6 drives the platform to perform longitudinal lifting and lowering. In the traction state, the traction limiting guide rail 3 and the opposing limiting column 5 limit the movement direction of the traction execution module 2, so that the net clothes rack support module 6 stably reaches the vertical lifting path, changes the lifting height of the net clothes rack support module 6, and realizes the platform lifting operation. During the lifting and lowering operation of the platform driven by the mesh rack support module 6, the lifting execution point processing unit 51, which is arranged in the longitudinal position of the opposing limiting support column 5, measures the overall lifting height of the directional roller transmission component 21. That is, the lifting execution point processing unit 51 measures the trigger signal of the directional roller transmission component 21 along the arc-shaped arrangement surface, determines whether the deviation of its signal response parameter exceeds the set threshold, and sends a switching signal to the platform traction end through the lifting execution point processing unit 51 according to the parameter exceeding the threshold. The platform traction end then makes a longitudinal fine adjustment to the position of the directional roller transmission component 21, that is, further corrects the height of the four sets of mesh rack support modules 6, so that the platform maintains stability in a horizontal state.
