Description

Technical Field

[0001] This utility model relates to the field of aquaculture racks, and more particularly to a climbing rack for snail farming. Background Technology

[0002] Snails (such as river snails, rock snails, and golden apple snails) have become an important species in freshwater aquaculture due to their short growth cycle, high feed conversion rate, and strong market demand. In recent years, with the continuous growth of consumer demand for snail products, snails, with their climbing and attachment biological characteristics, need to use hard surfaces to complete activities such as feeding and molting. However, current aquaculture relies heavily on natural waters or simple earthen ponds, lacking targeted attachment structures, resulting in limited activity space, low feeding efficiency, and prolonged growth cycles for snail populations. In existing improvement attempts, some farmers use simple materials such as netting and bamboo tubes as attachment substrates, but these structures suffer from uneven distribution and insufficient three-dimensional space development, making it difficult to meet the attachment needs of snails at different growth stages. Utility Model Content

[0003] In order to solve the problems in the background art, this utility model adopts the following technical solution:

[0004] A climbing frame for snail farming includes multiple sets of support columns fixedly installed in a pond. Multiple through holes communicating with the inner cavity are provided through the outer side of each support column. A fixed sleeve is fixedly fitted onto the outer side of the upper end of each support column, and a movable sleeve is slidably fitted onto the outer side of each support column. Positioning holes for positioning the movable sleeve are evenly arranged from top to bottom on the outer side of each support column. Multiple sets of symmetrical mounting plates are fixedly installed on the outer sides of the fixed and movable sleeves. Horizontal climbing rods are installed between the mounting plates on the outer side of the fixed sleeves, and inclined climbing rods are installed between the mounting plates on the outer side of the movable sleeves. Limiting pins are provided at the connection ends of the horizontal and inclined climbing rods with the mounting plates, and limiting holes are provided through the outer side of the mounting plates to engage with the limiting pins.

[0005] Preferably, the bottom of the support column is fixedly connected to a base, and the base is fixed in the pond by fasteners.

[0006] Preferably, a positioning pin is movably provided through the outer side of the movable sleeve and engages with the positioning hole. A handle is fixedly connected to the outer end of the positioning pin, and the inner side of the handle is connected to the outer side of the movable sleeve by a spring.

[0007] Preferably, the spring is in a contracted state by default.

[0008] Preferably, a counterweight is provided at the bottom of the inclined climbing pole.

[0009] Preferably, the limiting pin includes a spring telescopic pin fixedly connected to the outside of the horizontal climbing rod and the inclined climbing rod, an abutment plate fixedly connected to the outside of the spring telescopic pin and a limiting block fixedly connected to the outer end of the abutment plate and a limiting hole.

[0010] Compared with the prior art, the present invention has the following beneficial effects;

[0011] This invention features multiple sets of aquaculture climbing frames evenly distributed in a pond. Each climbing frame consists of support columns and horizontal and inclined climbing rods evenly arranged on the outer side. The through holes on the outer side of the support columns allow snails to crawl and move freely in the water. The height of the inclined climbing frames can be adjusted to adapt to the environment. This design not only achieves even distribution but also significantly enhances the three-dimensional spatial effect, effectively meeting the attachment needs of snails at different growth stages.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A snail farming climbing frame includes multiple sets of support columns 1 fixedly installed in a pond. Multiple sets of through holes 2 are provided through the outer side of the support columns 1, communicating with the inner cavity. A fixed sleeve 3 is fixedly sleeved on the outer side of the upper end of the support column 1. A movable sleeve 4 is also slidably sleeved on the outer side of the support column 1. Positioning holes 5 for positioning the movable sleeve 4 are evenly arranged from top to bottom on the outer side of the support column 1. Multiple sets of symmetrical mounting plates 6 are fixedly installed on the outer side of the fixed sleeve 3 and the movable sleeve 4. Horizontal climbing rods 8 are installed between the mounting plates 6 on the outer side of the fixed sleeve 3. Inclined climbing rods 9 are installed between the mounting plates 6 on the outer side of the movable sleeve 4. Limiting pins 10 are provided at the connection end of the horizontal climbing rods 8 and the inclined climbing rods 9 on the mounting plates 6. Limiting holes 7 are provided through the outer side of the mounting plates 6 to engage with the limiting pins 10.

[0022] The support column 1 is fixedly connected to a base 101 at its bottom, and the base 101 is fixed in the pond by fasteners 102, which facilitates the installation of the whole in the pond. In addition, multiple sets of support columns 1 are set so that they can be used relatively evenly in the pond.

[0023] The movable sleeve 4 has a locating pin 501 that engages with the locating hole 5 on its outer side. A handle 502 is fixedly connected to the outer end of the locating pin 501. The inner side of the handle 502 is connected to the outer side of the movable sleeve 4 via a spring 503, which is in a retracted state by default. The installation height of the movable sleeve 4 can be adjusted during use.

[0024] The inclined climbing pole 9 is equipped with a counterweight 901 at its bottom. The counterweight 901 tilts the angle of the inclined climbing pole 9 and increases the counterweight to prevent the inclined climbing pole 9 from being unable to maintain its tilt due to the impact of water flow.

[0025] The limiting pin 10 includes a spring telescopic pin 1001 fixedly connected to the outside of the horizontal climbing rod 8 and the inclined climbing rod 9. An abutment plate 1002 is fixedly connected to the outside of the spring telescopic pin 1001, abutting against the inner wall of the mounting plate 6. A limiting block 1003, which engages with the limiting hole 7, is fixedly connected to the outer end of the abutment plate 1002. The spring telescopic pin 1001 is in a spring-extended state by default. In use, the spring telescopic pin 1001 extends, causing the outer limiting block 1003 to engage in the limiting hole 7. Subsequently, the abutment plate 1002 abuts against the inner wall of the mounting plate 6 for support, completing the installation of the horizontal climbing rod 8 and the inclined climbing rod 9.

[0026] It should be added that the longitudinal section of the limiting block 1003 on the outer side of the horizontal climbing rod 8 is a regular polygon, preferably a regular octagon. The limiting hole 7 on the outer side of the mounting plate 6, which connects to the outer end of the horizontal climbing rod 8, is also a regular octagon. This ensures the relative stability of the horizontal climbing rod 8 during engagement, preventing rotation. However, the longitudinal section of the limiting block 1003 on the outer side of the inclined climbing rod 9 is circular. In this case, the limiting hole 7 on the outer side of the mounting plate 6, corresponding to the outer end of the inclined climbing rod 9, is also a circular hole design. After engaging the limiting hole 7, rotation is possible, facilitating the rotation and tilting of the inclined climbing rod 9.

[0027] Based on the above structural design, when using this device, the operator supports the support column 1 on the ground via the base 101, and fixes the support column 1 by using the fastener 102 to penetrate the ground. The height and tilt angle of the inclined climbing rod 9 can be adjusted by sliding the movable sleeve 4 on the outside of the support column 1 to meet the attachment requirements of snails at different growth stages. In specific operation, the operator pulls the handle 502 and stretches the spring 503, causing the positioning pin 501 to disengage from the positioning hole 5 on the outer end of the support column 1. Then, the height of the movable sleeve 4 can be adjusted by sliding it up and down. After the adjustment is completed, the operator releases the handle 502, and the positioning pin 501 is engaged in the corresponding positioning hole 5 under the elastic contraction of the spring 503, thus locking the height of the movable sleeve 4. At this time, the inclined climbing pole 9 is tilted and supported at the bottom of the pond by the weight of the bottom counterweight 901 and the rotation adjustment of the cylindrical limiting block 1003. The snails can climb up along the inclined climbing pole 9 and continue to rise through the through hole 2 on the outside of the support column 1 to the horizontal climbing pole 8 set horizontally for movement. The climbing frame can be evenly set in the pond, and the climbing poles themselves can enhance the overall three-dimensional space effect and meet the needs of snail farming.

[0028] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
