Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an escape-proof structure for an adult crab breeding pond. Background Art

[0002] As my country's aquaculture industry develops towards refinement and efficiency, adult crab farming has gradually become an important part of aquaculture in various places due to its high economic benefits and market demand. However, in the actual farming process, how to effectively solve the problem of adult crab escape has always been a key problem that troubles the majority of farmers. Although there are many types of anti-escape facilities on the market, a series of problems have been exposed in actual application, which seriously restricts the development of adult crab farming.

[0003] Most of the existing anti-escape facilities use anti-escape boards to block the breeding of adult crabs. In actual use, there is a problem of incomplete anti-escape effect. For large-sized river crabs that are mature and strong, their strong climbing ability makes conventional anti-escape structures easily damaged, resulting in a large number of adult crabs escaping and being lost. In addition, many anti-escape structures did not fully consider the use scenarios under extreme climatic conditions in the early design. For example, in heavy rain weather, due to poor material permeability or insufficient structural bearing capacity, the anti-escape board cannot effectively drain water, and collapse will occur when there is too much water in the pool. Most adult crab breeding sites are located along lakes and rivers and are greatly affected by wind. Some of the current anti-escape facilities are obviously lacking in wind resistance and ventilation performance. In a strong wind environment, anti-escape facilities made of lightweight materials are easily damaged or displaced, resulting in the failure of the anti-escape function and increasing the risk of crab escape. Therefore, it is necessary to propose an anti-escape structure for adult crab breeding ponds to solve the above-mentioned problems. Utility Model Content

[0004] In view of the problems in the related technology, the utility model proposes an escape-proof structure for an adult crab breeding pond to overcome the above-mentioned technical problems existing in the existing related technology.

[0005] To this end, the specific technical solutions adopted by the utility model are as follows:

[0006] An anti-escape structure for an adult crab breeding pond comprises a pond body, wherein a fixing pile is fixedly installed in the pond body, a fixing buckle is fixedly welded on one side of the surface of the fixing pile, an upper net is penetrated and installed in the fixing buckle, a wire is arranged inside the upper net, an anti-escape film is sewn and connected to the outer surface of the upper net, a lower net is sewn and connected to the end of the anti-escape film, the end of the lower net is fixedly installed in the pond body, a support frame is fixedly installed on one side surface of the fixing pile, a transmission bearing is fixedly installed inside the support frame, and an anti-escape roller is installed in the transmission bearing.

[0007] Furthermore, the spacing between the fixed piles installed on the pond body is between 1.5m and 2m.

[0008] Furthermore, the fixing buckle is a hexagonal nut with an inner diameter greater than 5 mm.

[0009] Furthermore, the upper net is a double-layer protective net with a mesh density of 40 meshes and a width of between 1cm and 2cm.

[0010] Furthermore, the wire is installed through the inside of the fixing buckle and the upper net, with a diameter of 3mm-4mm.

[0011] Furthermore, the anti-escape film is a polyvinyl chloride film with a width of 60 cm and a thickness greater than 0.3 mm.

[0012] Furthermore, the lower net is a single-layer protective net with a mesh density of 40 meshes and a total width greater than 30 cm. The distance buried in the ground plane is between 20 cm and 25 cm, and the distance left above the ground plane is between 5 cm and 10 cm.

[0013] The beneficial effects of the utility model are as follows: compared with the traditional anti-escape structure, the device is installed in combination of fixed piles, fixed buckles, an upper net, an anti-escape film and a lower net, so that the structure is simpler, the cost is low and the installation is convenient; the anti-escape film connected between the upper net and the lower net can effectively block the escape of river crabs; the lower net connected to the end of the anti-escape film allows the lower net to be buried in the upper and lower sides of the pond body respectively, which effectively prevents river crabs from digging holes to escape, and can also achieve ventilation and water permeability around the anti-escape structure, prevent strong winds and rainstorms from damaging the anti-escape structure, and effectively reduce losses.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1-Figure 3 According to an embodiment of the utility model, an anti-escape structure for an adult crab breeding pond includes a pond body 1, a fixed pile 2 is fixedly installed in the pond body 1, a fixed buckle 3 is fixedly welded on one side of the surface of the fixed pile 2, an upper net 4 is installed through the fixed buckle 3, a wire 5 is provided inside the upper net 4, an anti-escape film 6 is sewn and connected to the outer surface of the upper net 4, a lower net 7 is sewn and connected to the end of the anti-escape film 6, and the end of the lower net 7 is fixedly installed in the pond body 1, a support frame 8 is fixedly installed on one side surface of the fixed pile 1, a transmission bearing 9 is fixedly installed inside the support frame 8, and an anti-escape roller 10 is installed in the transmission bearing.

[0022] like Figure 1-3 As shown, the pond body 1 is usually formed by digging a groove in the soil and laying bricks on the edge of the pond wall, which is used to hold and cultivate crabs. The highest point of the pond wall edge is level with the horizontal plane and is used for fixing and inserting fixing piles 2.

[0023] Fixed pile 2: Made of DN25 galvanized steel pipe, each one is 1.5m long, driven vertically about 80cm below the ground level, with about 70cm exposed above the ground, with a distance of 1.5m-2m between the piles, used for embedding and fixing around the pond body to form the main support frame of the anti-escape structure.

[0024] Fixing buckle 3: A hexagonal nut with an inner hole larger than 5 mm is welded to the fixing pile and is located about 65 cm above the ground plane (1). The interior is used to prevent the upper net 4 from being moved.

[0025] Upper net 4: A double-layer protective net with a mesh density of 40 meshes and a width of 1cm-2cm, which is installed through the inside of the fixing buckle 3. The wire 5 passes through the interlayer of the upper net 4 to evenly fix the wire 5.

[0026] Wire 5: Made of 8#-10# iron wire, with a diameter of 3mm-4mm, it is used to conveniently penetrate and install in the upper net 4 so that the upper net 4 is evenly stressed.

[0027] Anti-escape film 6: Made of polyvinyl chloride film, with a thickness greater than 0.3 mm and a width of 60 cm, it is sewn with polyvinyl chloride thread at the bottom to the lower net 7 and at the top to the upper net 4 to block the climbing of river crabs and prevent them from escaping on a large scale.

[0028] Lower net 7: A single-layer protective net with a mesh density of 40 meshes, a total width greater than 30cm, 20cm-25cm of which is buried underground and fixed, and 5cm-10cm is left on the ground for ventilation and water permeability. The upper side of the net is sewn with polyvinyl chloride thread and the anti-escape film.

[0029] Support frame 8: A metal block fixedly welded to the surface of the fixed pile. A pair of metal blocks are welded to the surface of each fixed pile, and a circular groove is opened inside for installing the transmission bearing;

[0030] Support bearing 9: a cylindrical roller bearing with a diameter of 30 mm. The center hole of the bearing is used to install the anti-escape roller 10 to achieve the rotational installation of the anti-escape roller 10.

[0031] Anti-escape roller 10: A metal roller with a length of 1.5m-2m, with both ends rotatably installed in two support bearings, between the lower net 7 and the anti-escape film 8. When the river crab climbs, it rotates itself, further preventing the river crab from climbing upwards and escaping.

[0032] For example, in a certain place, there is an adult crab breeding pond, which is a low-density and large-scale breeding model. There are large crabs weighing about 8 taels. The anti-escape structure of the utility model is used instead. Compared with the original anti-escape structure, the anti-escape film 6 of the anti-escape structure is widened from 45cm to 60cm, which effectively prevents the escape of large river crabs. A lower net 7 is added to achieve timely drainage in rainstorm weather, solve the problem of the original anti-escape structure not dispersing water, and prevent the problem of accumulated water collapsing the anti-escape structure. After 6 years of use, the anti-escape structure of the utility model still functions normally.

[0033] To sum up, with the help of the above-mentioned technical scheme of the utility model, when in use, the anti-escape film 6 connected between the upper net 4 and the lower net 7 can effectively block the escape of river crabs; when river crabs climb through the anti-escape roller 10 with the help of the lower net, the anti-escape roller 10 itself rotates through the rotation installation, which can effectively hinder the river crabs from climbing upwards, thereby preventing the river crabs from climbing for a long time and causing damage to the anti-escape film 6; the lower net 7 connected to the end of the anti-escape film 6 is buried in the upper and lower sides of the pond body 1 respectively, which can effectively prevent river crabs from digging holes to escape, and can also achieve ventilation and water permeability around the anti-escape structure, preventing strong winds and rainstorms from damaging the anti-escape structure.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
