Description

Technical Field

[0001] This utility model applies to the field of fishing equipment and provides a fishpond escape prevention net. Background Technology

[0002] With the continuous development of aquaculture, fishpond farming has entered a stage of industrialization and large-scale operation. Modern fishpond farming not only focuses on the selection of fish species, feed management, and environmental control, but also increasingly emphasizes improving farming efficiency and production effectiveness. While meeting market demand, fishpond farming has gradually formed a stable industrial chain.

[0003] In fishpond farming, harvesting is a crucial aspect of aquaculture management. Traditional harvesting methods typically rely on equipment such as fishing nets and fishing vehicles. Fishermen need to set up nets and trawle them in the pond to successfully bring the fish ashore. Modern fishponds have also gradually introduced automated equipment, such as electrofishing devices and automatic fishing nets, which have greatly improved harvesting efficiency. However, whether operating manually or using machinery, the harvesting process often requires multiple adjustments based on the habits of different fish species and the environmental conditions within the pond.

[0004] However, in existing fishpond fishing processes, multiple fishing trips are usually required to catch the majority of the fish. Especially in larger or more complex fishpond environments, due to the uneven distribution of fish, a large number of fish are often missed during the fishing process, which significantly increases the time and workload of the fishing. Utility Model Content

[0005] To address the aforementioned deficiencies, the present invention aims to provide a fishpond escape-proof net, which solves the problems mentioned in the background art. The device includes a net cylinder with several pull lugs fixedly connected to it, and pull ropes fixedly connected to the pull lugs. The bottom of the net cylinder is provided with a bottom net bag, and an inflatable ring support is provided at the junction of the bottom net bag and the net cylinder. Several inflatable hoses are provided on the inflatable ring support, which can be expanded into a ring shape.

[0006] Furthermore, the inflatable ring support includes a ring support fabric sleeve, the inside of which is filled with an annular bladder. The annular bladder is made of elastic rubber material, and one end of the inflatable hose is connected to the annular bladder.

[0007] Furthermore, the mesh weave density of the bottom net bag is greater than that of the mesh weave density of the net cylinder.

[0008] Furthermore, the bottom net bag and the net cylinder are integrally connected, and a hose fixing strap is fixedly connected to the net cylinder; a plurality of hose fixing strips are fixedly connected to the hose fixing strap; the inflatable hose is located between the hose fixing strap and the hose fixing strips.

Detailed Implementation

[0018] 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.

[0019] It should be noted that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not 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. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] See Figure 1-3 The purpose of this utility model is to provide a fishpond escape prevention net, including a net cylinder 1; the net cylinder 1 is the main body of the fishing net. In this embodiment, a cylindrical fishing net is used (the grid of the fishing net has been omitted in the drawings for clarity. It can be understood that the net cylinder 1 is uniformly provided with mesh holes). The top of the net cylinder 1 is fixedly connected to a ring belt 101 with a certain strength. Several pull ears 11 are fixedly connected to the ring belt 101, and pull ropes 12 are fixedly connected to the pull ears 11.

[0023] The bottom of the net cylinder 1 is equipped with a bottom net bag 2, and an inflatable ring support 3 is provided at the junction of the bottom net bag 2 and the net cylinder 1; a hanging object 102 is also fixedly connected to the bottom of the net cylinder 1. Specifically, the inflatable ring support 3 is equipped with several inflatable hoses 31. It can be understood that the inflatable hoses 31 are hoses with a certain degree of softness and elasticity, which can be connected to external pumping equipment to inject or extract gas or liquid into the inflatable ring support 3. That is to say, the operator can inflate the inflatable ring support 3 into gas or liquid through the inflatable hoses 31, causing the inflatable ring support 3 to expand into a ring shape.

[0024] More specifically, the bottom net bag 2, the net tube 1, and the ring belt 101 are all connected by weaving or sewing processes. The bottom net bag 2 and the net tube 1 can be integrated by weaving. In one embodiment, the weaving density of the bottom net bag 2 is greater than that of the net tube 1.

[0025] Therefore, this fishpond escape-prevention net can be used for the cultivation and breeding of certain fish species in fishponds. In practical use, this fishpond escape-prevention net can be used simultaneously with the fishpond zoned fishing device designed by our company, see appendix. Figure 4 The fishpond zoning fishing device has a base 01 that can be installed on the edge of the fishpond. The base 01 has a hole in the center, and several columns 04 are located at the bottom of the base 01. A support base 06 is fixedly connected to the bottom of each column 04. The support base 06, columns 04, and base 01 together constitute the frame structure of the fishpond zoning fishing device. A ring net 05 composed of several thin circular rings is evenly arranged from top to bottom on each column 04. Several buffer devices 02 are installed on the top of the base 01, and these buffer devices 02 are evenly arranged in a ring on the top of the base 01. A fixing ring 03 is installed on the top of the base 01 on the side of the buffer device 02 away from the hole. A winch 07 is installed on the top of the base 01 on the side of one of the buffer devices 02 away from the hole.

[0026] This fishpond escape-proof net can be placed inside the fishpond zoned fishing device. Several pull ropes 12 can then correspond one-to-one with the buffer device 02 and the fixing ring 03. After lowering the net cylinder 1, the workers can tie the pull ropes 12 one by one to the fixing ring 03. The pull ropes 12 can also be placed on the buffer device 02, which flexibly counteracts the downward pulling force of the pull ropes 12. At this time, the workers can fill the inflatable ring support 3 with liquid through the inflatable hose 31, making the net cylinder 1 roughly match the density of water. Then, through the downward pulling force of the weight 102, the net cylinder 1 naturally expands downwards. Because the inflatable ring support 3 is filled with liquid, the bottom of the net cylinder 1 expands in a ring shape, fitting the bottom size of the fishpond zoned fishing device. Subsequently, fish farmers can cultivate fish fry inside the device in the fishpond. When it is time to harvest the net, they can first untie several ropes 12 and place them on the buffer device 02 corresponding to the winch 07. Then, the winch 07 is used to pull the net upward to complete the harvesting.

[0027] Preferably, a hose fixing strap 4 is fixedly connected to the mesh cylinder 1. A plurality of hose fixing strips 41 are fixedly connected to the hose fixing strap 4. An inflatable hose 31 is disposed between the hose fixing strap 4 and the hose fixing strips 41. Specifically, the hose fixing strap 4 and the hose fixing strips 41 are fixedly connected by sewing. The inflatable hose 31 is sandwiched between the hose fixing strap 4 and the hose fixing strips 41, thereby ensuring good bending margin for the inflatable hose 31 and preventing the hose from falling off or tangling.

[0028] Preferably, the inflatable ring support 3 includes a ring support fabric sleeve 32, which is made of fabric. The inside of the ring support fabric sleeve 32 is filled with an annular pouch 33, which is made of elastic rubber. One end of the inflation hose 31 is connected to the annular pouch 33. Thus, the annular pouch 33 is enclosed within the ring support fabric sleeve 32, and the annular pouch 33 can store gas or liquid. The ring support fabric sleeve 32 provides protection, preventing the annular pouch 33 from being scratched or ruptured.

[0029] In summary, in practical use, this fishpond escape-proof net can be placed inside the fishpond zoned fishing device. At this time, the pull rope 12 can be bound one-to-one with the buffer device 02 and the fixing ring 03. After the worker lowers the net cylinder 1, liquid is injected into the inflation ring support 3 through the inflation hose 31, making the density of the net cylinder 1 approximately match the density of water. Simultaneously, the weight 102 provides downward pulling force, causing the net cylinder 1 to naturally extend downwards, fitting the bottom shape of the fishpond zoned fishing device. During the aquaculture process, fish fry can be cultivated in the enclosed space formed by the net cylinder 1 and the bottom net bag 2. When it is time to harvest, the worker first unties the pull rope 12 and places it on the buffer device 02 corresponding to the winch 07, then operates the winch 07 to pull the net cylinder 1 upwards, completing the harvesting operation. During the net-closing process, workers can use other inflatable hoses 31 to extract liquid and fill in gas into the inflatable ring support 3. At this time, the bottom of the net cylinder 1 provides upward buoyancy, assisting the device in the net-closing operation and further improving efficiency.

[0030] Therefore, this device, through the effective combination of the net tube 1 and the bottom net bag 2, prevents the escape of farmed fish fry. Simultaneously, the inflatable ring support 3 and the weight 102 maintain the stability and extension of the net tube 1, ensuring sufficient farming space. Furthermore, the design of the hose fixing strap 4 and the hose fixing strip 41 ensures the fixation and bending margin of the inflatable hose 31, preventing it from falling off or tangling. The combination of the ring support cloth sleeve 32 and the annular bag 33 enhances the durability and safety of the inflatable ring support 3. This further improves harvesting efficiency and management convenience, while reducing operational difficulty and labor costs.

[0031] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
