Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to a special ladder suitable for factory-scale aquaculture ponds. Background Technology

[0002] In modern factory-style aquaculture, aquaculture ponds typically have specific structural and environmental characteristics. These ponds are mostly rectangular or circular, made of cement or fiberglass, with a depth generally ranging from 1.5 to 2.5 meters. The pond walls are vertical and smooth, and the edges are often constantly damp due to splashing water, sometimes even harboring algae, making the surface slippery. Workers need to frequently enter and exit the ponds for equipment maintenance, disease control, sorting and transferring fish, and harvesting and selling them. However, factory-style aquaculture ponds usually have limited width, and ladders often lack reliable anchoring, posing a risk of tipping over. In particular, the walls of common materials like PP, fiberglass, and galvanized corrugated sheets are typically only about 1 cm thick, making it difficult to enter and exit the pond due to the limited stress points.

[0003] Traditional ladders are prone to wobbling and uneven stress distribution, posing safety hazards. Furthermore, the variety of pond sizes means that traditional fixed-height ladders are difficult to adapt to different pond depths, forcing operators to frequently climb over them by hand. This makes it inconvenient for farmers to enter and exit the ponds. In addition, the above methods increase the labor intensity and safety risks for farmers when entering and exiting the ponds.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0035] Example 1.

[0036] like Figure 1-9 As shown, the present invention provides a special ladder suitable for factory-scale aquaculture ponds, including a fixed base 1 and climbing mechanisms slidably disposed at both ends of the fixed base 1.

[0037] The climbing mechanism includes a sliding plate 2 slidably mounted on a fixed base 1, a fixed ladder frame 3 hinged to the bottom of the sliding plate 2, a telescopic ladder frame 4 located at the bottom of the sliding plate 2, two sets of reinforcing mechanisms located between the fixed ladder frame 3 and the telescopic ladder frame 4, and an anti-slip mechanism located at the bottom of the fixed ladder frame 3 and the telescopic ladder frame 4.

[0038] In this invention, two climbing mechanisms are slidably mounted at both ends of the fixed base 1. The distance between the two climbing mechanisms can be adjusted by sliding the climbing mechanisms, so that one climbing mechanism is located inside the breeding pond and the other climbing mechanism is located outside the breeding pond, thereby facilitating the entry and exit of the breeding pond by the breeding personnel through the two climbing mechanisms.

[0039] In this invention, the sliding plate 2 is slidably mounted on the fixed base 1. By sliding the sliding plate 2, the distance between the two climbing mechanisms can be adjusted, so that the special ladder can be used in aquaculture ponds with different wall thicknesses.

[0040] In this invention, the fixed ladder frame 3 is hinged to the bottom of the sliding plate 2, and the telescopic ladder frame 4 is located at the bottom of the sliding plate 2. In use, the height of the special ladder can be adjusted by adjusting the angle between the fixed ladder frame 3 and the sliding plate 2, as well as the height of the telescopic ladder frame 4, so that the special ladder can be used in aquaculture ponds of different heights.

[0041] In this invention, two sets of reinforcing mechanisms can fix the fixed ladder frame 3 and the telescopic ladder frame 4, thereby preventing the fixed ladder frame 3 from sliding during use. At the same time, the anti-slip mechanism at the bottom of the fixed ladder frame 3 and the telescopic ladder frame 4 can effectively increase the friction of the climbing mechanism, thereby further reducing the probability of the fixed ladder frame 3 and the telescopic ladder frame 4 sliding during use.

In use, rotating adjusting rod 8 causes it to move within adjusting sleeve 7. After adjustment, adjusting rod 8 is connected to hinge seat A5 to fix the fixed ladder frame 3, thereby preventing the fixed ladder frame 3 from moving during use.

[0047] In this embodiment 2, the adjusting rod 8 is provided with an external thread, and the inner wall of the adjusting sleeve 7 is provided with an internal thread that matches the external thread. The adjusting rod 8 is threadedly connected inside the adjusting sleeve 7, so that the reinforcing mechanism can fix the fixed ladder frame 3 at different angles.

[0052] The hinge seat A5 is provided with a through connection hole A9, and the adjusting rod 8 is provided with a connection hole B10. The connection hole A9 and the connection hole B10 are connected by a pin 11.

[0053] In this embodiment 3, during use, the connecting hole B10 on the adjusting rod 8 is aligned with the connecting hole A9, and the pin 11 is inserted into the connecting hole A9 and the connecting hole B10 to fix the adjusting rod 8 on the hinge seat A5, thereby facilitating the fixing of the angle between the fixed ladder frame 3 and the sliding plate 2, thus facilitating the adjustment of the height of the special ladder.

[0069] In this embodiment 6, one end of each of the two vertical rods 16 is hinged to a corresponding hinge seat C15, and the other end is connected to the top of the connecting plate 12. Several horizontal bars 17 are equidistantly arranged between the two vertical rods 16. Aquaculture personnel can enter and exit the aquaculture pond by climbing the horizontal bars 17. In use, rotating the vertical rods 16 causes the two vertical rods 16 to rotate synchronously with the horizontal bars 17, thereby adjusting the distance between the fixed seat 1 and the top of the aquaculture pond, thus facilitating the adjustment of the height of the special ladder.

This allows for easy adjustment of the position of the climbing mechanism, making the special ladder suitable for aquaculture ponds with different wall thicknesses.

[0093] Working principle

[0094] When using this utility model, the special body is moved to the side of the breeding pond, and the sliding plate 2 is slid to make the distance between the two climbing mechanisms greater than the wall thickness of the breeding pond. After adjustment, it is fixed by bolts 25.

[0095] Next, slide the support rod 19 so that the height of the support rod 19 plus the sliding sleeve 20 is higher than the height of the breeding pond. Tighten the locking bolt 23 to fix the support rod 19. Rotate the vertical rod 16 so that the anti-slip pad 13 at the bottom of the vertical rod 16 can contact the top of the breeding pond. At the same time, by rotating the adjusting rod 8, adjust the length of the adjusting rod 8 so that the adjusting rod 8 can be connected to the hinge seat A5, thereby completing the adjustment of the special ladder. Place one climbing mechanism inside the breeding pond and the other climbing mechanism outside the breeding pond, so that the breeding personnel can enter and exit the breeding pond through the horizontal bar 17.
