Description

Technical Field

[0001] This utility model relates to the field of crab farming technology, and in particular to a flexible mesh fence structure to prevent crabs from escaping. Background Technology

[0002] Traditional pond aquaculture is limited by its small water area, poor water exchange, and susceptibility to diseases, making it difficult to meet the needs of large-scale crab farming. Enclosed aquaculture technology originated in large bodies of water such as lakes and reservoirs. It separates the aquaculture area from the natural water body through physical isolation, making use of the superior ecological conditions of the large body of water while improving aquaculture efficiency through artificial management.

[0003] Traditional crab farming enclosures mostly adopt a continuous, monolithic structure of tens or even hundreds of meters, with each part tightly connected and lacking a flexible opening design. When a section of the enclosure is damaged or it is necessary to inspect the crab farming situation inside, it is often necessary to dismantle the entire section or a large area of ​​the enclosure because it is impossible to quickly locate and open a specific area. This operation is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing traditional crab farming fences mostly adopt a continuous integral structure of tens or even hundreds of meters, with each part tightly connected and lacking a flexible opening design.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flexible mesh fence structure for preventing crab escape, comprising a fence support frame, wherein convenient disassembly components are provided on both sides of the fence support frame, the convenient disassembly components include a sliding groove, a flexible fence body is provided between the two sets of fence support frames, and connecting rods are bolted to both sides of the flexible fence body, a first slot is provided inside both sides of the fence support frame, two sets of first springs are connected inside the first slot, a push plate is connected to the front end of the two sets of first springs, an insert block is fixedly connected to the front end of the push plate, and a slot is provided on the outer side of the connecting rod.

[0006] Furthermore, the connecting rod is T-shaped, and it is slidably connected to the fence support frame via a slot.

[0007] Furthermore, the position and size of the slot match the position and size of the plug, and the plug and the slot form a mating connection.

[0008] Furthermore, the push plate and the first spring form an elastic structure, and the surface of the insert block is provided with an oblique opening.

[0009] Furthermore, an escape prevention component is connected to the top center of the fence support frame. The escape prevention component includes a vibration motor, and an infrared transmitter and a receiver are respectively connected to the two front ends of the vibration motor.

[0010] Furthermore, a conical block is connected to the bottom of the fence support frame, and guide grooves are provided inside both sides of the conical block. Guide blocks are slidably connected inside both sets of guide grooves.

[0011] Furthermore, a second slot is connected to the center of the conical block, a second spring is disposed inside the second slot, and a top block is connected to the top of the second spring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when it is necessary to disassemble a section of the flexible fence body, two sets of push plates can be pushed outwards at the same time, causing the insert block to be pulled out of the slot. Then, the connecting rod is pulled out upwards, so that the flexible fence body can be removed. This completes the disassembly of the fence in the area. This avoids the problem that traditional crab farming fences mostly adopt a continuous integral structure of tens or even hundreds of meters, with each part tightly connected and lacking a flexible opening design, which reduces the convenience of operation.

[0014] 2. In this invention, the infrared transmitter of the first set of fence support frames and the receiver of the other set of fence support frames form an infrared beam connection, creating an invisible infrared beam barrier. This technology can be used to detect whether crabs are attempting to escape. When a crab climbs the fence and blocks the infrared beam, the vibration motor automatically starts, causing the fence support frames to shake up and down, causing the crabs attached to the flexible fence to fall off automatically, thus preventing escape.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1 - Figure 3 As shown, this utility model provides a flexible mesh fence structure to prevent crabs from escaping, including a fence support frame 1. The fence support frame 1 has easily disassembled components 2 on both sides, each component including a sliding groove 201. A flexible fence body 202 is disposed between the two fence support frames 1. Connecting rods 203 are bolted to both sides of the flexible fence body 202. First slots 205 are formed inside both sides of the fence support frame 1, and two sets of first springs 206 are connected inside the first slots 205. The front end of 06 is connected to a push plate 207, and the front end of the push plate 207 is fixedly connected to an insert block 208. The outer side of the connecting rod 203 is provided with a slot 204. The connecting rod 203 is T-shaped. The connecting rod 203 is slidably connected to the fence support frame 1 through the slot 204. The position and size of the slot 204 match the position and size of the insert block 208. The insert block 208 and the slot 204 are connected by a plug-in connection. The push plate 207 and the first spring 206 form an elastic structure. The surface of the insert block 208 is provided with a bevel.

[0023] The effect achieved in Embodiment 1 is that when a section of the flexible fence body 202 needs to be disassembled, two operators can simultaneously push the push plates 207 on both sides of the flexible fence body 202 outwards, thereby causing the push plates 207 to compress the first spring 206, causing the insert block 208 to be pulled out of the slot 204. Then, the connecting rod 203 is pulled upwards, allowing the flexible fence body 202 to slide out of the slide groove 201 through the connecting rod 203, completing the disassembly. When installation is required, the flexible fence body 202 can be disassembled by pushing the push plates 207 on both sides of the flexible fence body 202 outwards. The connecting rods 203 are inserted into the grooves 201 of the two sets of fence support frames 1 respectively. After the oblique opening of the insert 208 is squeezed, it will automatically retract. After the connecting rods 203 are fully pushed into the grooves 201, the first spring 206 will push the push plate 207 to drive the insert 208 to be inserted into the slot 204 for fixing. This completes the disassembly of the fence in the area. This avoids the problem that most traditional crab farming fences adopt a continuous integral structure of tens or even hundreds of meters, with each part tightly connected and lacking a flexible opening design, which reduces the convenience of operation.

[0024] Example 2, as Figure 1 and Figure 4 As shown, an escape prevention component 3 is connected to the top center of the fence support frame 1. The escape prevention component 3 includes a vibration motor 301. An infrared transmitter 302 and a receiver 303 are respectively connected to the two sides of the front end of the vibration motor 301. A conical block 304 is connected to the bottom of the fence support frame 1. Guide grooves 305 are opened inside both sides of the conical block 304. Guide blocks 306 are slidably connected inside the two sets of guide grooves 305. A second slot 307 is connected to the center of the conical block 304. A second spring 308 is installed inside the second slot 307. A top block 309 is connected to the top of the second spring 308.

[0025] The effect achieved in Embodiment 2 is that, in the flexible mesh fence system for preventing crab escape, an infrared transmitter 302 is installed on the first set of fence support frames 1, and a receiver 303 is installed on the corresponding second set of fence support frames 1. The two together form an infrared beam connection, creating an invisible infrared beam barrier. This technology is cleverly applied to the crab escape detection stage. When a crab attempts to climb the fence, its body blocks the infrared beam. Once the receiver 303 detects that the beam is blocked, it immediately sends a signal to the controller. Upon receiving the signal, the controller reacts quickly and automatically activates the vibration motor 301 in that area. After the vibration motor 301 starts, it causes the fence support frame 1 to vibrate up and down rhythmically. This vibration is transmitted to the flexible fence body 202, and the top block 309 at the bottom of the flexible fence body 202 repeatedly compresses the second spring 308 as the support frame vibrates. During the compression and release process, the second spring 308 undergoes elastic deformation, which in turn causes the flexible fence body 202 to shake more violently. The swaying of the flexible fence body 202 causes the crabs attached to it to lose their balance and fall off automatically, effectively preventing them from escaping. At the same time, this escape prevention method does not cause serious harm to the crabs, ensuring their health and the profitability of aquaculture.

[0026] Working principle: When it is necessary to disassemble a section of the flexible fence body 202, both sets of push plates 207 can be pushed outwards simultaneously, causing the insert block 208 to be pulled out of the slot 204. Then, the connecting rod 203 can be pulled upwards to remove the flexible fence body 202. This completes the disassembly of the area fence, avoiding the problem that traditional crab farming fences mostly adopt a continuous monolithic structure of tens or even hundreds of meters, with each part tightly connected and lacking flexible opening design, which reduces the convenience of operation. The infrared transmitter 302 of the first set of fence support frame 1 and the receiver 303 of the other set of fence support frame 1 form an infrared beam connection, forming an invisible infrared beam barrier. This technology can be used to detect whether crabs are trying to escape. When a crab climbs the fence and blocks the infrared beam, the vibration motor 301 automatically turns on, causing the fence support frame 1 to shake up and down, so that the crabs attached to the flexible fence body 202 can fall off automatically, achieving the effect of preventing escape.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
