Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a kind of aquaculture equipment. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under artificial control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. Aquaculture is divided into extensive breeding, intensive breeding and high-density intensive breeding. Among them, high-density intensive breeding adopts methods such as flowing water, temperature control, oxygenation and feeding bait to carry out high-density breeding in small water bodies. In order to facilitate management and reduce the floor space, existing fish farming usually uses aquaculture equipment to breed fish.

[0003] The Chinese invention patent application with application number 202010781394.4 provides a technical solution for an aquaculture tank, which discloses an intelligent energy-saving and emission-reducing high-efficiency aquaculture water tank. The aquaculture water tank discharges materials or fish feces through the bottom of the aquaculture water tank body and the discharge pipe, which is convenient for the clean and thorough discharge of fish excrement, and the inside of the device is heated by a heating rod.

[0004] However, the above patent has the following defects: 1. The above patent mainly completes the discharge through the discharge pipe, but it cannot ensure that the fish are at the bottom of the breeding water tank. Therefore, most of the water in the breeding water tank needs to be discharged before the fish can be discharged. Due to the limited diameter of the discharge pipe, it is easy to cause the discharge pipe to be blocked, and the fish in the breeding water tank cannot be guided when passing through the discharge pipe. Therefore, the fish are easily scratched when discharged from the discharge pipe, thereby affecting the survival rate of the fish after discharge, and then affecting the selling value.

[0005] 2. When the fish excrement is discharged, the discharged water cannot be filtered, so the fish excrement remaining in the water cannot be processed. If it is poured into the river, it is easy to affect the environment, and the discharged water cannot be recycled, thus wasting water resources. Summary of the invention

[0034] See also Figure 2 , Figure 3 and Figure 4The fishing unit 4 includes a fixing frame 41, and a fixing frame 41 is installed on the inner wall of the tank body 1 and near its lower side. Waterproof cylinders 42 are installed at the four corners of the upper end of the fixing frame 41. The telescopic ends of the four waterproof cylinders 42 are jointly provided with a linkage frame 43. A baffle net 44 is hinged on the right side of the upper end of the linkage frame 43 through a first torsion spring. Through the setting of the first torsion spring, the baffle net 44 always has a torsional force for rotating downward. The baffle net 44 is an elastic telescopic structure composed of a fixed end and two telescopic ends. The front and rear side walls of the baffle net 44 are both slidably connected to the front and rear side inner walls of the tank body 1, and the left end of the baffle net 44 is rotatably connected to a resistance roller 441, and the resistance roller 441 is rollingly connected to the inner wall of the left end of the tank body 1; a positioning bar 45 is provided on the right side of the upper end of the baffle net 44, and a plurality of pull ropes 46 are installed on the right end of the positioning bar 45 at equal intervals from front to back, and the pull ropes 46 are away from the fixed One end of the positioning strip 45 passes through the baffle net 44 and the linkage frame 43 in sequence and is connected to the upper end of the fixing frame 41. A supporting block 47 is installed on the left side of the upper end of the linkage frame 43. The lower end of the baffle net 44 abuts against the supporting block 47 on the left side. An oxygenation component 48 is arranged at the lower end of the linkage frame 43. A fish outlet 49 is opened at the right end of the tank body 1. The right end of the fish outlet 49 gradually tilts downward. A guide cylinder 491 is arranged at the right end of the fish outlet 49. The side of the guide cylinder 491 close to the fish outlet 49 is parallel to the fish outlet 49, and the end of the guide cylinder 491 away from the fish outlet 49 is a vertical section. The distance between the front and rear sides of the vertical section gradually decreases from top to bottom. The fish discharged from the fish outlet 49 can be guided by the guide cylinder 491 to facilitate the collection of the caught fish. In the initial state, the waterproof cylinder 42 is in a retracted state, and the baffle net 44 is in a horizontal state (such as Figure 2 As shown), the fish in the tank body 1 are all located above the baffle net 44.

[0035] See also Figure 4 The oxygenation assembly 48 includes an oxygenation pump 481, and the oxygenation pumps 481 are arranged on the left and right sides of the bottom of the linkage frame 43 through the mounting frame, and a hollow tube 482 is arranged between the two oxygenation pumps 481. The front and rear sides of the hollow tube 482 are both installed with U-shaped tubes 483 connected thereto, and the upper ends of the hollow tubes 482 and the U-shaped tubes 483 are evenly provided with air outlets 484, and a plurality of connecting frames 485 are installed at equal intervals from left to right between the U-shaped tubes 483 and the bottom of the linkage frame 43, and the U-shaped tubes 483 can be limited and fixed by the connecting frames 485; in actual application of the present invention, when breeding fish, the oxygenation pump 481 is started, and the oxygenation pump 481 transports oxygen to the hollow tubes 482 and the U-shaped tubes 483, and then the oxygen is transported to the water through the plurality of air outlets 484 at the same time, thereby enhancing the oxygen supply to the fish to ensure that the fish in the tank body 1 will not be short of oxygen.

[0036] During specific operation, when it is necessary to catch the fish in the tank body 1, the waterproof cylinder 42 is started, the telescopic end of the waterproof cylinder 42 is extended and drives the linkage frame 43, the barrier net 44 and the positioning bar 45 to move upward as a whole, and the barrier net 44 drives the fish on its upper end to move upward. At this time, the distance between the positioning bar 45 and the fixed frame 41 gradually increases, so that the pull rope 46 applies a pulling force to the positioning bar 45, so that the barrier net 44 rotates to the right under the action of the positioning bar 45, and the telescopic end on the left side of the barrier net 44 drives the resistance roller 441 to always resist the left inner wall of the tank body 1 under its own elastic action, thereby preventing the barrier net 44 from having a gap between the inner wall of the fish tank body 1, thereby preventing the fish from falling through the gap, and when the linkage frame 43 moves upward to the highest position, the barrier net 44 is flush with the lower side wall of the fish outlet 49, and the barrier net 44 is in an inclined state (such as Figure 3 As shown in the figure, the fish on the upper end of the baffle net 44 are discharged after passing through the fish outlet 49 and the guide cylinder 491, thereby completing the fish catching operation and achieving high catching efficiency. In addition, since the upper end of the baffle net 44 is flush with the lower side wall of the fish outlet 49 and the two adjacent pull ropes 46 can form a guide groove, the fish can slide down from the baffle net 44 and pass through the fish outlet 49 more smoothly without being scratched, thereby ensuring the survival rate of the fish caught from the tank body 1, and the inclined baffle net 44 can buffer the discharged fish. The effect is to allow fish to pass through the fish outlet 49 one after another, thereby not causing blockage of the fish outlet 49. In addition, the water in the tank body 1 will not be discharged during the process of catching fish, so that the water in the tank body 1 can continue to be used. After the fish are caught, the waterproof cylinder 42 drives the linkage frame 43 and the barrier net 44 to move downward and reset. At this time, the barrier net 44 loses the tension of the pull rope 46 and rotates downward under the action of the first torsion spring. Then, the left side of the lower end of the barrier net 44 abuts against the upper end of the supporting block 47. At this time, the barrier net 44 returns to a horizontal state.

[0037] See also Figure 2 and Figure 5After the aquaculture tank has been used for a period of time, fish excrement and dirt will appear in the water. If not handled in time, it is easy to affect the water quality, thereby affecting the growth environment of the fish. In view of this technical problem, the present invention provides a sewage discharge unit 5, which includes a conical cylinder 51. The bottom of the tank body 1 is detachably provided with a receiving cylinder 52 through the conical cylinder 51 connected thereto.

[0038] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 The interception assembly 55 includes a positioning plate 551. The inner wall of the tank body 1 is provided with a positioning plate 551 below the fixing frame 41. The positioning plate 551 is provided with a plurality of water drop holes 552 arranged in a matrix. A plug-in plate 553 is slidably connected inside the positioning plate 551. The left end of the plug-in plate 553 slides through the tank body 1. The plug-in plate 553 is provided with a plurality of through holes 554 arranged alternately with the water drop holes 552. Two clearance grooves 555 are symmetrically provided on the left side of the tank body 1 about the plug-in plate 553. Linkage plates 556 slidably connected to the clearance grooves 555 are installed on the upper and lower sides of the plug-in plate 553. A contraction spring 557 is provided between the linkage plate 556 and the right side wall of the clearance groove 555. The contraction spring 557 is always coupled to the linkage plate 556. The movable plate 556 applies a rightward contraction force, and a clamping member 558 is provided at the left end of the linkage plate 556; the clamping member 558 is composed of a first hinge plate 559 and a second hinge plate 550, wherein: a rhombus groove is provided on the left side wall of the yielding groove 555, and the left end of the linkage plate 556 is hinged with the first hinge plate 559 symmetrically up and down, and the left end of the first hinge plate 559 is hinged with the second hinge plate 550 through a second torsion spring, and two adjacent second hinge plates 550 are rotatably connected away from the side of the linkage plate 556; the second torsion spring is provided to enable the first hinge plate 559 and the second hinge plate 550 to have a relative rotational torsional force; in the initial state, the through holes 554 on the plug plate 553 and the water drop holes 552 on the positioning plate 551 are arranged alternately (such as Figure 7As shown), the water drop hole 552 is blocked by the plug plate 553 to prevent the water in the tank body 1 from flowing out of the water drop hole 552. In addition, the excrement and dirt of the fish in the water are accumulated on the upper end of the positioning plate 551.

[0039] See also Figure 1 , Figure 5 and Figure 6 The water circulation component 56 includes a water pump 561. The water pump 561 is installed on both the front and rear sides of the water receiving cylinder 54. A drain pipe 562 is installed at the water outlet end of the water pump 561. The end of the drain pipe 562 away from the water pump 561 passes through the tank body 1 and extends into the interior thereof. The water inlet pipe of the water pump 561 extends into the interior of the water receiving cylinder 54 and is installed with a filter cover 563. An activated carbon filter element 564 is detachably arranged inside the filter cover 563.

[0040] When working, the plug plate 553 is pulled to the left, and the plug plate 553 drives the first hinge plate 559 and the second hinge plate 550 to move to the left and insert into the diamond groove, so that the first hinge plate 559 and the second hinge plate 550 are both against the inner wall of the diamond groove, thereby fixing the linkage plate 556, and then limiting and fixing the plug plate 553. At this time, the through hole 554 coincides with the water drop hole 552 (such as Fig. 9 As shown in the figure, the water on the upper end of the positioning plate 551 together with the excrement and dirt of the fish pass through the water drop hole 552, the conical cylinder 51, the first filter screen 53 and the second filter screen 521 in sequence and then flow into the water receiving cylinder 54. During this period, the excrement and dirt of the fish in the water can be filtered in multiple stages through the first filter screen 53 and the second filter screen 521 to enhance the filtering effect of the water, thereby ensuring the cleanliness of the water flowing into the water receiving cylinder 54. Then, the plug-in plate 553 is pushed to the right, and the plug-in plate 553 drives the first hinge plate 559 and the second hinge plate 550 to be pulled out of the diamond groove through the linkage plate 556. Then, the linkage plate 556 drives the plug-in plate 553 to return to the position under the action of the contraction spring 557. In the initial state, in order to facilitate the blocking of the drain hole 552, it is only necessary to filter the water at the bottom of the tank body 1 to filter out the fish excrement and dirt in the water, and then start the water pump 561. The water inlet end of the water pump 561 draws out the water in the water receiving cylinder 54 and discharges it into the tank body 1 through the drain pipe 562. During this period, the water in the water receiving cylinder 54 can be purified through the filter cover 563 and the activated carbon filter element 564, so as to ensure that the purified water quality meets the use standards, thereby completing the water recycling; after the water in the water receiving cylinder 54 is completely pumped out, the receiving cylinder 52 is removed and the dirt on the upper ends of the first filter screen 53 and the second filter screen 521 is cleaned, and then the receiving cylinder 52 is installed and reset.

[0041] The working process of the present invention is as follows: S1: When it is necessary to catch fish in the tank body 1, start the waterproof cylinder 42, the waterproof cylinder 42 drives the linkage frame 43, the barrier net 44 and the positioning bar 45 to move upward as a whole, and the barrier net 44 drives the fish on its upper end to move upward. At this time, the pull rope 46 applies a pulling force to the positioning bar 45 to make the barrier net 44 rotate to the right. When the linkage frame 43 moves upward to the highest position, the barrier net 44 is flush with the lower side wall of the fish outlet 49. At this time, the barrier net 44 is in an inclined state, so that the fish on the upper end of the barrier net 44 are discharged after passing through the fish outlet 49 and the guide cylinder 491, thereby completing the fish catching operation.

[0042] S2: After the fish are caught, the waterproof cylinder 42 drives the linkage frame 43 and the barrier net 44 to move downward and reset. At this time, the barrier net 44 loses the tension of the pull rope 46 and rotates downward under the action of the first torsion spring. Then, the lower left side of the barrier net 44 abuts against the upper end of the supporting block 47. At this time, the barrier net 44 returns to a horizontal state.

[0043] S3: When it is necessary to filter the excrement and dirt of the fish in the water, the plug plate 553 is pulled to the left and drives the first hinge plate 559 and the second hinge plate 550 to move to the left and insert into the diamond groove, so as to limit and fix the linkage plate 556 and the plug plate 553. At this time, the through hole 554 coincides with the water drop hole 552. The water on the upper end of the positioning plate 551, together with the excrement and dirt of the fish, passes through the water drop hole 552, the conical cylinder 51, the first filter screen 53 and the second filter screen 521 in sequence and then flows into the water receiving cylinder 54. During this period, the water passes through the first filter screen 53. The second filter net 521 can perform multi-stage filtration on the excrement and dirt of the fish in the water, so as to ensure the cleanliness of the water flowing into the water receiving tube 54. Then, the plug-in plate 553 is pushed to the right, and the plug-in plate 553 drives the first hinge plate 559 and the second hinge plate 550 to be pulled out of the diamond groove through the linkage plate 556. Then, the linkage plate 556 drives the plug-in plate 553 to reset under the action of the contraction spring 557, so as to block the water drop hole 552. In this way, the excrement and dirt of the fish in the water can be filtered out by filtering the water at the bottom of the tank body 1.

[0044] S4: Start the water pump 561. The water inlet end of the water pump 561 draws out the water in the water receiving cylinder 54 and discharges it into the tank body 1 through the drain pipe 562. During this period, the water in the water receiving cylinder 54 can be purified through the filter cover 563 and the activated carbon filter element 564, thereby ensuring that the purified water quality meets the use standards, thereby completing the water recycling.

[0045] S5: After the water in the water receiving cylinder 54 is completely pumped out, the receiving cylinder 52 is removed and dirt on the upper ends of the first filter screen 53 and the second filter screen 521 is cleaned, and then the receiving cylinder 52 is installed and reset.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
