Description

Technical Field

[0001] This utility model relates to the field of fencing technology, specifically a steel structure fence for aquaculture that is easy to set up. Background Technology

[0002] Livestock fencing, also known as wire mesh fencing, Dutch mesh fencing, enclosure fencing, and enclosure iron wire mesh, is mainly made of high-quality iron wire welded together. PVC, PE, or PP powder is coated onto its surface after vulcanization treatment, resulting in strong adhesion, good corrosion resistance, and a bright color.

[0003] Chinese patent CN216438251U discloses a convenient steel structure fence for aquaculture, comprising three base plates. From left to right, a wire reel, a height limit bar, and a wire guide are fixedly connected to the top of each base plate. A stabilizing device is located at the bottom of each base plate, and a fixing device is located inside the wire reel. This convenient steel structure fence for aquaculture offers advantages such as ease of installation, solving the problem that most existing aquaculture fences rely on numerous steel nails or bolts for ground fixing, requiring significant time for installation and disassembly, resulting in inconvenient setup. Furthermore, the extensive removal and installation of steel nails and bolts increases the workload for aquaculture workers.

[0004] However, fixed-height fences cannot adapt to different types and growth stages of farmed animals. Furthermore, when multiple fences are assembled, they can only be extended in a straight line at the same level and cannot be bent or adjusted according to different sites and farming needs. Therefore, a steel structure fence that is easy to set up for farming is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a convenient steel structure fence for aquaculture, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conveniently arranged steel structure fence for aquaculture, comprising support rods, each support rod having a first telescopic groove; an extension rod slidably disposed within the first telescopic groove, the extension rod having multiple positioning holes; a fixing hole communicating with the first telescopic groove on the support rod, a bolt inserted into the fixing hole, a nut at one end of the bolt, the bolt passing through the positioning hole corresponding to the fixing hole and being screwed to the nut; a concave block and a convex block are respectively fixedly installed on one side of two support rods, the concave block having a locking hole, the convex block having a telescopic cavity and a movable cavity, a slider slidably disposed within the telescopic cavity, a locking rod adapted to the locking hole fixedly connected to one side of the slider, a spring connected between the other side of the slider and the telescopic cavity, a hand-twisting rod rotatably disposed on the convex block and rotatably connected to the movable cavity, a rope wheel fixedly sleeved on the hand-twisting rod, a steel wire rope wound on the rope wheel, the free end of the steel wire rope passing through the movable cavity and extending into the telescopic cavity to connect with the slider.

[0007] Preferably, there are two support rods, and a support plate is fixedly connected between the two support rods. Multiple guardrails are installed on the support plate.

[0008] Preferably, the guardrail has a second telescopic groove, a telescopic rod is slidably disposed in the second telescopic groove, and a top plate is fixedly disposed on the top of the extension rod and the telescopic rod.

[0009] Preferably, a base plate is installed at the bottom of the support rod, and an installation hole is provided on the base plate, into which an anchor nail for fixing the support rod is inserted.

[0010] Preferably, the concave block and the convex block are interlocked, and there are two telescopic cavities, which are located at the upper and lower ends of the movable cavity, respectively.

[0011] Preferably, the end of the locking rod away from the slider slides through the telescopic cavity and engages in the lock hole, and the locking rod is rotatably connected to the lock hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This convenient steel structure fence for aquaculture can extend the fence height by removing bolts and nuts, lifting the top plate upwards, and allowing the extension rod to slide along the first expansion groove and the second expansion groove. After adjustment, the bolts are inserted into the fixing holes and passed through the corresponding positioning holes before being screwed into the nuts, thus locking the extension rod in the position and fixing the adjusted fence. This allows for flexible adjustment of the fence height according to different types and growth stages of aquaculture animals, improving the fence's flexibility and versatility.

[0014] 2) This conveniently arranged steel structure fence for aquaculture uses a hand-operated lever to wind up the wire rope. The slider is pulled by the tension of the wire rope, compressing the spring and causing the locking rod to retract into the telescopic cavity. Then, the concave and convex blocks on adjacent fences are aligned, and the locking holes on the concave blocks are aligned with the locking rods on the convex blocks. Then, the hand-operated lever is released, and the locking rod automatically engages in the locking hole under the spring's rebound, completing the connection between the two fences. The locking rod can rotate within the locking hole, allowing the fence to be bent and adjusted to adapt to different sites and aquaculture needs, effectively improving the fence's flexibility and expandability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figures 1-4A convenient steel structure fence for aquaculture includes two support rods 1. A support plate 2 is fixedly connected between the two support rods 1. Multiple guardrails 3 are installed on the support plate 2. A base plate 4 is installed at the bottom of the support rod 1. The base plate 4 has mounting holes, and anchor nails 5 for fixing the support rod 1 are inserted into the mounting holes.

[0023] See Figure 2 and Figure 3 Furthermore, the support rod 1 has a first telescopic groove 6, an extension rod 11 is slidably arranged in the first telescopic groove 6, the extension rod 11 has multiple positioning holes 12, the support rod 1 has a fixing hole 8 communicating with the first telescopic groove 6, a bolt 9 is inserted in the fixing hole 8, a nut 10 is provided at one end of the bolt 9, the bolt 9 passes through the positioning hole 12 corresponding to the fixing hole 8 and is screwed to the nut 10; the guardrail 3 has a second telescopic groove 7, a telescopic rod 13 is slidably arranged in the second telescopic groove 7, and a top plate 14 is fixedly provided on the top of the extension rod 11 and the telescopic rod 13.

[0024] Specifically, by removing bolt 9 and nut 10, the top plate 14 is pulled upwards, causing the extension rod 11 to slide along the first telescopic groove 6 and the telescopic rod 13 to slide along the second telescopic groove 7, thus extending the height of the fence. After adjustment, bolt 9 is inserted into the fixing hole 8 and passed through the corresponding positioning hole 12 before being screwed to nut 10, thereby locking the extension rod 11 in that position and fixing the adjusted fence. This allows for flexible adjustment of the fence height according to different types and growth stages of farmed animals, improving the flexibility and versatility of the fence.

[0025] See Figure 2 and Figure 4 Furthermore, it is found that a concave block 15 and a convex block 17 are fixedly installed on one side of each of the two support rods 1. A locking hole 16 is provided on the concave block 15, and a telescopic cavity 18 and a movable cavity 19 are provided in the convex block 17. The concave block 15 and the convex block 17 are interlocked. There are two telescopic cavities 18, which are located at the upper and lower ends of the movable cavity 19, respectively. A slider 20 is slidably arranged in the telescopic cavity 18. A locking rod 21 that matches the locking hole 16 is fixedly connected to one side of the slider 20. The end of the slider 20 away from the slider 20 slides through the telescopic cavity 18 and is locked into the lock hole 16. The locking rod 21 is rotatably connected to the lock hole 16. A spring 22 is connected between the other side of the slider 20 and the telescopic cavity 18. A hand-twisting rod 23 is rotatably mounted on the protrusion 17 and is rotatably connected to the movable cavity 19. A rope wheel 24 is fixedly mounted on the hand-twisting rod 23. A steel wire rope 25 is wound on the rope wheel 24. The free end of the steel wire rope 25 passes through the movable cavity 19 and extends into the telescopic cavity 18 to connect with the slider 20.

[0026] Specifically, by rotating the hand-tightening lever 23, the rope wheel 24 winds up the wire rope 25. The slider 20 is pulled by the tension of the wire rope 25, compressing the spring 22 and causing the locking lever 21 to retract into the telescopic cavity 18. Then, the concave block 15 and the protrusion 17 on the adjacent fence are aligned, and the locking hole 16 on the concave block 15 is aligned with the locking lever 21 on the protrusion 17. Then, the hand-tightening lever 23 is released, and the locking lever 21 automatically engages in the locking hole 16 under the rebound of the spring 22, completing the connection between the two fences. The locking lever 21 can rotate in the locking hole 16, thereby allowing the fence to be bent and adjusted to adapt to different sites and breeding needs, effectively improving the flexibility and expandability of the fence.

[0027] In actual operation, the fence is fixed to the ground using anchor nails 5 and base plate 4. By removing bolts 9 and nuts 10, the top plate 14 is pulled upward, so that the extension rod 11 slides in the first telescopic groove 6 and the telescopic rod 13 slides in the second telescopic groove 7, thereby extending the height of the fence. This allows for flexible adjustment of the fence height according to different types and growth stages of farmed animals. After adjustment, the bolts 9 are inserted into the fixing holes 8 and passed through the corresponding positioning holes 12 and screwed into the nuts 10, so that the extension rod 11 can be locked in the position, thereby fixing the adjusted fence.

[0028] When assembling multiple fences, turn the hand-tightening lever 23 to wind the rope wheel 24 around the wire rope 25. The slider 20 is pulled by the tension of the wire rope 25, which compresses the spring 22 and drives the locking rod 21 to retract into the telescopic cavity 18. Then, align the concave block 15 and the protrusion 17 on the adjacent fences, and align the locking hole 16 on the concave block 15 with the locking rod 21 on the protrusion 17. Then, release the hand-tightening lever 23, so that the locking rod 21 automatically engages in the locking hole 16 under the rebound of the spring 22, completing the connection between the two fences. The locking rod 21 can rotate in the locking hole 16, which makes it easy to bend and adjust the fence according to the site or breeding needs.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
