Description

Technical Field

[0001] This utility model relates to the field of aquaculture cages for marine engineering, and in particular to a corrosion-resistant rack and pinion lifting unit and a truss cage containing the lifting unit. Background Technology

[0002] In recent years, nearshore aquaculture in my country has approached saturation, making the promotion of deep-sea cage aquaculture imperative. To achieve modular and standardized production of aquaculture cages, existing modular aquaculture cages (such as patent numbers ZL202410973141.5, ZL202410972984.3, ZL202421728072.3, ZL202421736120.3, ZL202421727018.7, ZL202421727276.5, and ZL202421727298.1) are designed with modular and standardized components, including legs, cage body, and lifting installation units. This results in a high degree of component standardization, fast installation, high transshipment capability, and low transportation costs, effectively meeting the needs of the developing deep-sea aquaculture industry.

[0003] However, existing modular cages (such as patent ZL202421727298.1, a rack and pinion lifting unit for a modular cage and a modular cage) disclose a rack and pinion lifting unit 100', such as Figure 1 As shown, the drive unit 1' is indirectly fixedly mounted on the lifting mounting unit 3' via the mounting base 2', and moves freely up and down on the pile leg 200' along with the lifting mounting unit 3'. However, the drive unit 1' is frequently immersed in seawater, inevitably leading to seawater corrosion, reducing the service life of parts, and increasing subsequent maintenance costs. In addition, the existing single mounting base 2' is indirectly fixedly mounted on the lifting mounting unit 3'. This mounting method results in a certain meshing gap when the climbing gear on the drive unit 1' meshes with the rack on the pile leg 200', reducing the stability of the meshing transmission. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a corrosion-resistant rack and pinion lifting unit and a truss cage containing the lifting unit.

[0005] One of the objectives of this utility model is achieved through the following technical solution: a corrosion-resistant rack and gear lifting unit, comprising a drive device, a climbing gear, an annular mounting base, a lug extension connection structure, and a lifting mounting unit. The annular mounting base includes an annular seat and limiting mounting boxes symmetrically arranged on both sides of the outer diameter of the annular seat.

The drive device is mounted on the limiting mounting box, and the power output shaft of the drive device passes through the gear cavity and is connected to the climbing gear inside the gear cavity. One end of the lug extension connection structure is connected to the bottom of the limiting mounting box, and the other end is connected to the lifting mounting unit.

[0006] The climbing gear meshes with the rack on the pile leg to drive the lifting installation unit to move up and down along the pile leg.

[0007] Furthermore, the ear extension connection structure includes a first ear portion, a second ear portion, and a connecting piece connecting the first ear portion and the second ear portion; the first ear portion is fixedly installed on the limiting mounting box, the second ear portion is fixedly installed on the lifting mounting unit, and the two ends of the connecting piece are respectively hinged to the first ear portion and the second ear portion.

[0008] Furthermore, both the first and second hanging ears include two parallel hanging ear pieces, each of which is integrally formed with respect to the annular mounting base and the lifting mounting unit.

[0009] Furthermore, the outer periphery of the annular seat is provided with a plurality of first reinforcing ribs arranged in a crisscross pattern, and the connection between the limiting mounting box and the annular seat is provided with a plurality of second reinforcing ribs.

[0010] Furthermore, the number of driving devices is four, with two driving devices installed on each limiting mounting box, and each driving device is arranged in a vertical direction.

[0011] Furthermore, the drive device includes a lifting motor, a coupling, a gearbox, and a brake; the lifting motor is connected to the gearbox via the coupling, and the climbing gear is fixedly mounted on the drive shaft of the gearbox; the brake is mounted on one side of the lifting motor and is used to stop the lifting motor in an emergency.

[0012] Furthermore, the lifting and mounting unit has an inner ring portion, which is recessed with a third cavity for accommodating the rack on the pile leg; the third cavity corresponds one-to-one with the second cavity on the annular seat; the inner ring portion of the lifting and mounting unit is sleeved on the pile leg, and the outer periphery of the lifting and mounting unit is provided with an installation component for installing the mesh cage surface module, and the mesh cage surface module of the modular mesh cage is detachably installed on the installation component; the hanging ear extension connection structure is connected to the top surface of the lifting and mounting unit.

[0013] The second objective of this utility model is achieved by the following technical solution: a self-elevating truss gabion, comprising pile legs, gabion surface modules, and the anti-corrosion rack and gear lifting unit as described above; the anti-corrosion rack and gear lifting unit is installed on the pile legs, and the gabion surface modules are installed between the pile legs through the rack and gear lifting unit.

[0014] Furthermore, in the self-elevating truss gabion, the gabion surface module includes a side module, a top module, and a bottom module. The self-elevating truss gabion is a cage-shaped spatial truss structure, constructed from multiple modular side modules, top modules, and bottom modules.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This application improves the installation method of the drive device by adding a hanging ear extension connection structure and optimizing the installation structure of the drive device.

On the other hand, the two-piece hanging ear pieces are integrally formed with the annular mounting base and the lifting mounting unit, which can improve the firmness of the entire hanging ear extension connection structure and improve the overall transmission stability.

[0020] 4. This application further optimizes the structure of the annular mounting base by designing a variety of different reinforcing ribs on the annular mounting base, so that it can not only meet the strength requirements of the annular mounting base itself, but also meet the load-bearing capacity and ocean current impact force required during lifting and lowering movements.

[0021] 5. Compared with the existing single mounting base structure, this mounting base is improved into a ring mounting base. The ring mounting base is directly fitted onto the pile leg, which further optimizes the meshing space between the rack and the climbing gear. There is no meshing gap, and the transmission stability between the two is better. Attached Figure Description

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0045] like Figure 2-8As shown, the present invention provides a corrosion-resistant rack and pinion lifting unit 100, including a drive device 1, a climbing gear 2, an annular mounting base 3, a lug extension connection structure 4, and a lifting mounting unit 5. The annular mounting base 3 includes an annular seat 31 and limiting mounting boxes 32 symmetrically arranged on both sides of the outer diameter of the annular seat 31. The annular seat 31 has a first cavity 311 for mounting a pile leg 200. The corrosion-resistant rack and pinion lifting unit 100 is sleeved on the pile leg 200 through the first cavity 311. The first cavity 311 is recessed to accommodate the pile. The second cavity 312 of the rack 201 on the leg 200; the limiting mounting box 32 is provided with a gear cavity 321 for mounting the climbing gear 2 on the side away from the outer diameter, the gear cavity 321 is connected to the second cavity 312, the drive device 1 is mounted on the limiting mounting box 32, the power output shaft of the drive device 1 passes through the gear cavity 321 and is connected to the climbing gear 2 in the gear cavity 321; one end of the hanging ear extension connection structure 4 is connected to the bottom of the limiting mounting box 32, and the other end is connected to the lifting mounting unit 5;

[0046] The climbing gear 2 meshes with the rack 201 on the pile leg 200 to drive the drive device 1 to drive the lifting installation unit 5 to move up and down along the pile leg 200.

[0047] This application improves the installation method of the drive device 1 by adding a hook extension connection structure 4 and optimizing the installation structure of the drive device 1. Specifically, the added hook extension connection structure 4 can increase the distance between the drive device 1 and the lifting installation unit 5, reducing the probability of seawater corrosion and immersion.

[0048] As a further preferred embodiment, the ear extension connection structure 4 includes a first ear portion 41, a second ear portion 42, and a connecting piece 43 connecting the first ear portion 41 and the second ear portion 42; the first ear portion 41 is fixedly installed on the limiting mounting box 32, the second ear portion 42 is fixedly installed on the lifting mounting unit 5, and the two ends of the connecting piece 43 are respectively hinged to the first ear portion 41 and the second ear portion 42.

[0049] This application further improves the structure of the ear extension connection structure 4 by adding a connecting piece 43 and installing it by hinge, forming a floating connection structure between the lifting installation unit 5 and the limiting installation box 32, so that the load on the left and right sides of the cage is evenly distributed during typhoons and normal operation.

[0051] This application designs the first ear portion 41 and the second ear portion 42 as two-piece ear pieces 411 / 421. On the one hand, by installing the connecting piece 43 between the two ear pieces 411 / 421, the contact area between the connecting piece 43 and the connecting piece 43 can be increased, thereby improving assembly stability. On the other hand, the two-piece ear pieces 411 / 421 are integrally formed with the annular mounting base 3 and the lifting mounting unit 5, respectively, which can improve the firmness of the entire ear extension connection structure 4 and improve the overall transmission stability.

[0053] This application further optimizes the structure of the annular mounting base 3 by designing various reinforcing ribs on the annular mounting base 3, so that it can meet the strength requirements of the annular mounting base 3 itself, as well as the load-bearing capacity and ocean current impact force required during lifting and lowering movements.

[0054] As a further preferred embodiment, the number of driving devices 1 is four, with two driving devices 1 installed on each limiting mounting box 32, and each driving device 1 arranged along the vertical direction.

[0055] Compared to the existing single mounting base structure, this mounting base is improved into a ring mounting base 3, which is directly fitted onto the pile leg 200, thereby further optimizing the meshing space between the rack 201 and the climbing gear 2. There is no meshing gap, resulting in better transmission stability between the two.

[0056] As a further preferred embodiment, the drive device 1 includes a lifting motor 11, a coupling 12, a reduction gearbox 13, and a brake 14. The lifting motor is connected to the reduction gearbox via the coupling, and the climbing gear 2 is fixedly mounted on the drive shaft of the reduction gearbox. The brake is mounted on one side of the lifting motor for emergency stopping. When the lifting motor suddenly loses power, the brake is triggered to stop the motor, reducing the risk to the entire cage during lifting operations. Optionally, the brake is selected from PRECIMA brakes from Germany and is a spring-loaded dry friction electromagnetic brake. The reduction gearbox of this application is equipped with a swivel reducer and a planetary reducer, which are sequentially arranged at the output end of the lifting motor. The climbing gear 2 is mounted on the drive shaft of the planetary reducer, so that the entire cage body can be driven to lift and lower stably via wired or wireless control.

[0057] As a further preferred embodiment, the lifting and mounting unit 5 has an inner ring portion 51, which is recessed with a third cavity 52 for accommodating the rack 201 on the pile leg 200; the third cavity 52 corresponds one-to-one with the second cavity 312 on the annular seat 31; the inner ring portion 51 of the lifting and mounting unit 5 is sleeved on the pile leg 200, and the outer periphery of the lifting and mounting unit 5 is provided with a mounting component 53 for mounting the mesh cage surface module 300, and the mesh cage surface module 300 of the modular mesh cage is detachably mounted on the mounting component 53; the hanging ear extension connection structure 4 is connected to the top surface of the lifting and mounting unit 5.

[0058] This solution also provides a self-elevating truss gabion, including pile legs 200, gabion surface module 300, and corrosion-resistant rack and gear lifting unit 100 as described above; the corrosion-resistant rack and gear lifting unit 100 is installed on the pile legs 200, and the gabion surface module 300 is installed between the pile legs 200 through the rack and gear lifting unit.

[0059] As a further preferred embodiment, in the self-elevating truss gabion, the gabion surface module 300 includes a side module 301, a top module 302, and a bottom module 303. The self-elevating truss gabion is a cage-shaped spatial truss structure, constructed from multiple modular side modules 301, top modules 302, and bottom modules 303. Each gabion surface module 300 is detachably mounted on the pile leg 200 via a lifting and mounting unit 5. The side module 301 is located on the side of the modular gabion body and forms the side of the cage-shaped spatial truss structure. The top module 302 is located on the top surface of the modular gabion body and forms the top of the cage-shaped spatial truss structure. The bottom module 303 is located on the bottom surface of the modular gabion body and forms the bottom of the cage-shaped spatial truss structure.

[0060] The standardization of each side module 301, top module 302, and bottom module 303 in this application is high. Each side module can be assembled, maintained, and repaired independently, resulting in a short construction time. This reduces the difficulty of overall assembly and maintenance required for integrally welded cages in the prior art, while simplifying maintenance and expansion and extending the service life of aquaculture cages.

The horizontal cross-sectional shape of the net cage body can be various, such as triangular, square, rectangular, grid-shaped, quadrilateral, pentagonal, hexagonal, octagonal, etc., or it can be assembled sequentially from multiple individual "square" modular net cages, such as double-square, triple-square, multi-square, etc., or assembled sequentially from multiple individual "rectangular" modular net cages, such as quadrilateral, hexagonal, octagonal, etc., to increase the aquaculture volume, achieve rapid modular expansion of the aquaculture area, and improve the applicability of the aquaculture net cage.

[0063] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model.
