Description

Technical Field

[0001] The present invention relates to the technical field of fish farming, and in particular to a marine farming protection device and a use method thereof. Background Art

[0002] Marine aquaculture is a production activity that utilizes coastal shallow sea flats to cultivate marine aquatic economic plants and animals. It includes shallow sea aquaculture, tidal flat aquaculture, and harbor aquaculture. When traditional marine farmed fish are released into the aquaculture waters, guide plates or guide cylinders are usually used to guide the fish into the aquaculture ponds. This treatment method is likely to cause damage to the fish when released. Therefore, in the prior art, temporary cages are usually used to directly release them into the aquaculture waters, and the cage doors are opened after entering the sea to allow the fish to swim out to the waters on their own. Although this treatment method can achieve the purpose of protecting fish, it has the following problems: some fish tend to remain inside the cage in order to avoid light and cannot quickly adapt to the new water environment. In actual application, manual operation is required to drive out the remaining fish in the cage. Therefore, although the protection effect is achieved, the release efficiency is not ideal. To this end, we propose a marine aquaculture protection device and a method for using it. Summary of the invention

[0003] The main purpose of the present invention is to provide a marine aquaculture protection device and a method of using the same.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0006] The sending and receiving guide protective member includes an extension limit sleeve, a traction and winding motor, a traction baffle and a traction rope member, the extension limit sleeve is fixedly connected to the inner side of the outlet end frame, the traction and winding motor is fixedly connected to the top of the extension limit sleeve, one end of the traction rope member is fixedly connected to the output end of the traction and winding motor, the other end of the traction rope member is fixedly connected to the traction baffle, and the end of the traction baffle away from the traction rope member is fixedly connected to the main body bracket.

[0007] A further improvement of the present invention is that a mesh connecting groove is provided at one end of the tilting guide frame, and the mesh connecting groove is used to safely guide the farmed fish at the outlet end frame position to the farmed tank by connecting to the external farmed tank mesh.

[0008] A further improvement of the present invention is that the sedimentation cage includes a flow area frame and a bottom interception frame, the flow area frame is fixedly connected to the main support, the bottom interception frame is fixedly connected to the flow area frame, the bottom interception frame is communicated with the flow area frame, and the flow area frame is communicated with the main support.

[0009] A further improvement of the present invention is that interception side nets are provided on the left and right sides of the flow area frame and the bottom interception frame, and front and rear blocking nets are provided on the front and rear sides of the flow area frame and the bottom interception frame. The interception side nets and the front and rear blocking nets are used to isolate the flow area frame and the bottom interception frame into independent placement areas.

[0010] A further improvement of the present invention is that the lead-out end driving assembly includes a tail end isolation bracket, a shaking driving rope and a sonic wave driving device, the tail end isolation bracket is fixedly connected to the bottom of the sedimentation cage, the shaking driving rope is embedded in the inner side of the tail end isolation bracket, and the sonic wave driving device is fixedly connected between the main body bracket and the tail end isolation bracket.

[0011] A further improvement of the present invention is that a method for using a marine aquaculture protection device comprises the following steps:

[0012] Step S1, placing the cultured fish into the inner side of the flow area rack through the opening of the main frame, and then placing the flow area rack into the pre-treatment water area so that the water level of the water treatment water area covers the flow area rack, and the flow area rack is used for isolation culture before multiple batches of fish are mixed and placed;

[0013] Step S2, after the isolation culture is completed for a fixed time, the flow area frame is continuously lowered into the pre-treatment water area, so that the water level of the pre-treatment water area submerges the flow area frame and the bottom interception frame, and then the net sleeve connecting groove is connected with the external culture tank net sleeve, so that the fish can swim along the layered light shielding plate arrangement surface under the action of daily light source. Since the outlet end frame area is completely shielded from light, the fish gradually pass through the tilting guide frame area under the light shielding guidance of the layered light shielding plate to reach the inner side of the outlet end frame, and swim to the culture area through the culture tank net sleeve, so as to realize the guidance of the fish when being released into the culture area;

[0014] Step S3, starting the shaking driving rope and the sonic driving device provided at the upper end of the tail end isolation bracket, and driving the fish still remaining in the flow area frame and the inner side of the bottom interception frame by the shaking driving rope and the sonic driving device, so that the remaining fish are driven by the secondary driving action and swim to the inner side of the outlet end frame through the tilting guide frame, and swim to the breeding area through the breeding tank net sleeve connected to the net sleeve connecting groove;

[0015] Step S4, start the traction and winding motor, so that the output end of the traction and winding motor pulls the traction rope to wind up, lifts the traction barrier net toward one end of the traction rope, reduces the space inside the outlet end frame, and makes the fish inside the outlet end frame pushed by the traction barrier net to quickly swim to the breeding area through the breeding tank net sleeve connected to the net sleeve connecting groove. At this time, the self-swimming release of the isolated breeding fish into the breeding pond is completed.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: isolation and breeding are carried out before multiple batches of fish are mixed and released through the flow area frame. After the isolation and breeding is carried out for a fixed time, the net sleeve connecting groove is connected to the external breeding tank net sleeve, so that the fish can be driven by daily light sources to swim along the layered light-shielding plate arrangement surface. Since the outlet end frame area is completely shielded from light, the fish gradually pass through the tilting guide frame area under the light-shielding guidance of the layered light-shielding plate to reach the inner side of the outlet end frame, and swim to the breeding area through the breeding tank net sleeve. At the same time, by setting a traction and winding motor, the traction rope can be driven to be wound, and the traction barrier net is lifted toward one end of the traction rope, reducing the space inside the outlet end frame, so that the fish inside the outlet end frame are pushed by the traction barrier net and quickly swim to the breeding area through the breeding tank net sleeve connected to the net sleeve connecting groove. At this time, the self-swimming release of the isolated and cultured fish into the breeding pond is completed, thereby ensuring the release protection effect while achieving the purpose of rapid expulsion.

[0024] Example

[0025] See also Figure 1-Figure 5 , including a sinking cage 1 and a main body support 3, the main body support 3 is installed on the top of the sinking cage 1, and a driving protection guide component 2 is fixedly connected to the top of the main body support 3, and the driving protection guide component 2 includes a tilting guide frame 21, a layered light-shielding plate 22, a closing support plate 23 and an outlet end frame 24, and the outlet end frame 24 is arranged at one end of the tilting guide frame 21, the layered light-shielding plate 22 is fixedly connected to the upper end of the tilting guide frame 21, and the layer thickness of the layered light-shielding plate 22 increases along the lateral distribution, the closing support plate 23 is fixedly connected to the inner side of the outlet end frame 24, and a sending and receiving guide protection member 4 is arranged between the tilting guide frame 21 and the outlet end frame 24, and an outlet driving component 5 is arranged at the bottom of the sinking cage 1, and the outlet driving component 5 is used to drive the fish to the inner side of the tilting guide frame 21.

[0026] In an optional implementation of the present embodiment, the receiving and delivering guiding protective member 4 includes an extension limit sleeve 41, a traction and winding motor 42, a traction barrier net 43 and a traction rope member 44, the extension limit sleeve 41 is fixedly connected to the inner side of the outlet end frame 24, the traction and winding motor 42 is fixedly connected to the top of the extension limit sleeve 41, one end of the traction rope member 44 is fixedly connected to the output end of the traction and winding motor 42, the other end of the traction rope member 44 is fixedly connected to the traction barrier net 43, and the end of the traction barrier net 43 away from the traction rope member 44 is fixedly connected to the main support 3.

[0027] In this embodiment, in order to solve the problem in the prior art that fish tend to remain inside the cage in order to avoid light and cannot quickly adapt to the new water environment, manual operation is required to drive out the remaining fish in the cage in actual application. Therefore, although the protection effect is achieved, the release efficiency is not ideal. The present invention proposes a marine aquaculture protection device, which solves the technical problem by providing a driving and protection guide component 2, a main body bracket 3, a receiving and sending guide protection piece 4 and an outlet driving component 5.

[0028] In an optional implementation of this embodiment, a mesh connecting groove 25 is opened at one end of the tilting guide frame 21, and the mesh connecting groove 25 is used to safely guide the farmed fish at the position of the outlet end frame 24 to the breeding tank by connecting the external breeding tank mesh.

[0029] In the present embodiment, the present invention mainly uses the light-shielding property of fish to drive the fish into the aquaculture waters. The principle is that since the structure of the layered light-shielding plate 22 is an inclined design, the thickness of the end close to the outlet end frame 24 gradually increases, so the shading effect increases smoothly. Therefore, the water level of the pre-treated water area can be used to submerge the flow area frame 11 and the bottom interception frame 12, and then the net sleeve connecting groove 25 is connected to the external aquaculture tank net sleeve, so that the fish can be driven by daily light sources to swim along the arrangement surface of the layered light-shielding plate 22. Since the outlet end frame 24 area is completely shielded from light, the fish gradually pass through the tilting guide frame 21 area under the light-shielding guidance of the layered light-shielding plate 22 to reach the inner side of the outlet end frame 24, and swim to the aquaculture area through the aquaculture tank net sleeve, thereby realizing the guidance of the fish when they are released into the aquaculture area.

[0030] In this embodiment, after the fish gather and arrive at the inner side of the outlet end frame 24, the traction winding motor 42 drives the traction rope 44 to shrink along the inner side of the extension limit sleeve 41. At this time, the traction blocking net 43 is pulled by the traction rope 44, and a single end is displaced along the extension limit sleeve 41, thereby isolating the connection position between the layered light-shielding plate 22 and the outlet end frame 24, and reducing the space between the net sleeve connecting groove 25 and the breeding tank net sleeve, so that the fish can quickly enter the breeding tank net sleeve through the net sleeve connecting groove 25, and finally swim from the breeding tank net sleeve to the inner side of the breeding pond, thereby completing the protection purpose and accelerating the guiding speed of the fish.

[0031] The settling cage 1 includes a flow area frame 11 and a bottom interception frame 12. The flow area frame 11 is fixedly connected to the main support 3, the bottom interception frame 12 is fixedly connected to the flow area frame 11, the bottom interception frame 12 is communicated with the flow area frame 11, and the flow area frame 11 is communicated with the main support 3.

[0032] In an optional implementation of the present embodiment, interception side nets 13 are provided on the left and right sides of the flow area frame 11 and the bottom interception frame 12, and front and rear blocking nets 14 are provided on the front and rear sides of the flow area frame 11 and the bottom interception frame 12. The interception side nets 13 and the front and rear blocking nets 14 are used to isolate the flow area frame 11 and the bottom interception frame 12 into independent placement areas.

[0033] In this embodiment, the flow area frame 11 and the bottom interception frame 12 can be assembled side by side after being released. The flow area frame 11 and the bottom interception frame 12 are supported in the pretreatment area. The setting of the interception side net 13 and the front and rear blocking nets 14 can isolate multiple batches of fish in the pre-exit area.

[0034] In an optional implementation of this embodiment, the lead-out end driving assembly 5 includes a tail end isolation bracket 51, a shaking driving rope 52 and a sound wave driving device 53, the tail end isolation bracket 51 is fixedly connected to the bottom of the sedimentation cage 1, the shaking driving rope 52 is embedded in the inner side of the tail end isolation bracket 51, and the sound wave driving device 53 is fixedly connected between the main bracket 3 and the tail end isolation bracket 51.

[0035] In this embodiment, after the set release time is reached, the fish still remaining in the flow area frame 11 and the inner side of the bottom interception frame 12 are driven away by setting a vibration motor to shake the driving rope 52, and cooperating with the sonic drive device 53 to emit sonic waves, so that the remaining fish are driven away by the secondary driving action through the tilting guide frame 21 to the inner side of the outlet end frame 24, and swim to the breeding area through the breeding tank net connected to the net connecting groove 25.

[0036] The working principle of the present invention is: the farmed fish are put into the inner side of the flow area frame 11 through the opening of the main frame 3, and then the flow area frame 11 is loaded into the pre-treatment water area, so that the water level of the water treatment water area covers the flow area frame 11, and the flow area frame 11 is used to isolate and culture the fish before multiple batches of fish are mixed and put in. The farmed fish are put into the inner side of the flow area frame 11 through the opening of the main frame 3, and then the flow area frame 11 is loaded into the pre-treatment water area, so that the water level of the water treatment water area covers the flow area frame 11, and the flow area frame 11 is used to isolate and culture the fish before multiple batches of fish are mixed and put in. After the isolated culture is carried out for a fixed time, the flow area frame 11 is continuously lowered into the pre-treatment water area so that the water level in the pre-treatment water area submerges the flow area frame 11 and the bottom interception frame 12, and then the net sleeve connecting groove 25 is connected with the external culture tank net sleeve, so that the fish can be driven by daily light sources to swim along the arrangement surface of the layered light-shielding plate 22. Since the outlet end frame 24 area is completely shielded from light, the fish gradually pass through the tilting guide frame 21 area under the light-shielding guidance of the layered light-shielding plate 22 to reach the inner side of the outlet end frame 24, and swim to the culture area through the culture tank net sleeve, thereby realizing the guidance of the fish when being released into the culture area. The shaking driving rope 52 and the sonic driving device 53 provided at the upper end of the tail end isolation bracket 51 are started, and the fish still remaining in the inner side of the flow area frame 11 and the bottom interception frame 12 are driven away by the shaking driving rope 52 and the sonic driving device 53, so that the remaining fish are concentratedly swam to the inner side of the outlet end frame 24 through the tilting guide frame 21 under the secondary driving effect, and swim to the breeding area through the breeding tank net sleeve connected to the net sleeve connecting groove 25. The traction winding motor 42 is started, and the traction rope member 44 at the output end of the traction winding motor 42 is wound up, and the traction blocking net 43 is lifted toward one end of the traction rope member 44, reducing the inner space of the outlet end frame 24, so that the fish inside the outlet end frame 24 are pushed by the traction blocking net 43 and quickly swim to the breeding area through the breeding tank net sleeve connected to the net sleeve connecting groove 25, and at this time, the self-swimming release of the isolated breeding fish into the breeding pond is completed.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
