A multi-type fish fry release device

Abstract

This invention discloses a multi-type fish fry release device, including a fish fry release and transport body and a base plate movably installed at the bottom of the fish fry release and transport body. A water storage tank is rotatably connected to the top of the outer side of the fish fry release and transport body via a sealing ring. The fish fry release and transport body has a release pre-storage chamber inside, and inlet holes are evenly distributed along the axis inside the fish fry release and transport body. This invention discharges water from inside the water storage tank into the release pre-storage chamber through the inlet holes and outlet holes, causing the pre-stored water inside the release pre-storage chamber to rise to the bottom of the release outlet. This shortens the height difference between the release outlet and the partition, allowing the fish fry to flow into the release pre-storage chamber first during release. This greatly reduces the impact force of the fish fry falling into the release pre-storage chamber when discharged into the release pre-storage chamber. The release outlet of the fish fry release hose is placed in a natural water area, allowing the fish fry inside the release pre-storage chamber to be discharged into the natural water area through the soft fish fry release hose for release.

Description

Technical Field

[0001] This invention relates to the field of fish fry release technology, and in particular to a multi-type fish fry release device. Background Technology

[0002] In response to the severe situation of declining aquatic biological resources, deteriorating aquatic ecological environment, and increasing aquatic desertification, it is increasingly important to actively carry out stock enhancement and release activities. Artificial stock enhancement and release involves directly releasing or transferring eggs, larvae, or adults of fishery organisms into natural waters such as oceans, tidal flats, rivers, lakes, and reservoirs using artificial methods to restore or increase population numbers, improve and optimize the community structure of the water area. Stock enhancement and release is an effective means of replenishing fishery resources, improving and restoring the ecological environment damaged by overfishing or water conservancy projects, and maintaining biodiversity. Depending on the characteristics of different water areas, it can supplement and restore species missing in the original aquatic food chain, thus playing a role in protecting aquatic biological germplasm resources.

[0003] Chinese Patent Application Publication No. CN118160654A, published on June 11, 2024, discloses a fish fry release device, including a transfer device and a set of oxygenation devices installed on the transfer device. The transfer device includes a frame, with two sets of sprockets rotatably connected to the frame. Each set of sprockets consists of two sprockets, and a chain is rotatably connected to the outer side of each set of sprockets. The two chains are staggered, and a set of fish boxes is connected between the two chains. The oxygenation device includes a base, an outer tube, and a drive disc rotatably connected to the base. The outer tube is fixedly connected to the turntable, and the turntable is connected to the drive disc. An inner tube is slidably connected to the outer tube. The outer tube is connected to the rotating tube through gears and racks, and the inner tube is connected to the drive disc. A set of fish boxes is connected to the chain. When the fish boxes move on the upper part of the chain, the guide shaft slides in the upper guide groove of the upper part of the frame. When the fish boxes move on the lower part of the chain, the guide shaft slides in the lower guide groove of the bottom of the frame. The fish fry release device has the following defects: the device tilts too high during the release process, which may cause the fish fry to be injured or even die due to excessive impact, thus affecting the survival rate of the fish fry; in addition, the fish fry release device uses a single fish box to transport the fish fry, which cannot release multiple types of fish fry, resulting in low release efficiency.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0029] Please see Figures 1-9A multi-type fish fry release device includes a fish fry release and transport body 1 and a base plate 2 movably installed at the bottom of the fish fry release and transport body 1. A water storage tank 101 is rotatably connected to the top of the outer side of the fish fry release and transport body 1 via a sealing ring. A pre-storage chamber 102 is provided inside the fish fry release and transport body 1. Input holes 103 are evenly distributed along the axis inside the fish fry release and transport body 1. Water discharge holes 104, communicating with the input holes 103, are evenly distributed along the axis at the bottom of the inner side of the water storage tank 101. A partition 105 is fixedly installed inside the pre-storage chamber 102. The top of the partition 105 is inclined towards the axis, and the bottom of the partition 105 is fixed... A discharge pipe 106 is fixedly installed through the bottom of the fish fry release and transport body 1. A valve 107 is fixedly installed inside the bottom of the discharge pipe 106. A fish fry release hose 108 is fixedly connected to the bottom of the discharge pipe 106 by bolts. A receiving cavity 109 is set at the bottom inside the fish fry release and transport body 1. An electric telescopic rod 110 is rotatably installed on one side of the top of the fish fry release and transport body 1, which is rotatably connected to the top of the water storage tank 101. The bottom plate 2 is movably installed at the opening at the bottom of the receiving cavity 109. A hanging rod 201 is fixedly installed along the axis at the bottom of the partition plate 105. A winding rod sleeve 202 fixed to the top of the bottom plate 2 is sleeved on the outside of the hanging rod 201.

[0030] With the above-described structure, this multi-species fish fry release device stores various types of fish fry separately in the fish fry storage box 3, enabling the device to transport multiple types of fish fry to natural water areas for release. Then, by retracting the output end of the electric telescopic rod 110, the water storage tank 101 rotates, connecting the inlet hole 103 with the outlet hole 104. Next, the water storage tank 101 discharges water into the release pre-storage chamber 102 through the inlet hole 103 and the outlet hole 104, thus allowing the release pre-storage chamber 102 to... The tank is filled with pre-stored water, raising the water level to the bottom of the discharge port. The output end of the electric telescopic rod 110 extends, causing the water storage tank 101 to rotate, thus misaligning the inlet port 103 with the outlet port 104, closing the drain port. Then, the fish fry inside the fish fry storage box 3 are discharged into the pre-stored water inside the discharge pre-storage chamber 102, preventing the fish fry from being impacted and becoming unwell when they fall from a height. Subsequently, the output port of the fish fry discharge hose 108 is placed into the river water, and then the valve 107 is opened. This method allows fish fry inside the pre-storage chamber 102 to be directly released into the river water through the release pipe 106 and the fish fry release hose 108, avoiding fish fry death due to collisions during release. It also allows for intermittent release of different species of fish fry, improving the survival rate of released fry. After the release is complete, the fish fry release hose 108 is detached from the bottom of the release pipe 106 and then wound around... On the outside of the winding rod sleeve 202, the winding rod sleeve 202 moves upward on the outside of the hanging rod 201, causing the hanging rod 201 to retract into the inside of the winding rod sleeve 202, thereby driving the bottom plate 2 to move upward and store the fish fry release hose 108 inside the storage cavity 109. This prevents the fish fry release hose 108, which is installed at the bottom of the release pipe 106, from being damaged during transportation, which could cause the fish fry to leak out through the damaged area and die when released.

[0031] Furthermore, a support ring 111 is fixedly installed inside the fish fry release and transportation body 1. The fish fry storage box 3 is located on top of the support ring 111. A release port 301 is opened on the inner side of the fish fry storage box 3. A sealing door 302 is movably installed inside the release port 301 through a sealing strip. The support ring 111 can support the fish fry storage box 3, allowing it to be installed on top inside the fish fry release and transportation body 1 for transporting and storing fish fry. By opening the sealing door 302, different types of fish fry inside each fish fry storage box 3 can be released intermittently.

[0032] Furthermore, water inlets 112 are fixedly installed on both sides of the top of the water storage tank 101, and a waterstop plate 303 is fixedly installed on the bottom of the inner side of the sealing door 302. The water inlets 112 facilitate the replenishment of pre-stored water into the water storage tank 101, allowing pre-stored water to be continuously injected into the pre-stored discharge chamber 102 to shorten the discharge height difference. This ensures that the fish fry can fall directly into the pre-stored water inside the pre-stored discharge chamber 102 after being discharged from the discharge outlet 301, thus improving the survival rate of the released fish fry. When the sealing door 302 is closed, the waterstop plate 303 is located inside the fish fry storage box 3 to provide water-stop protection and prevent water leakage from the fish fry storage box 3 that could lead to the death of the fish fry.

[0033] Furthermore, a sealing cover 304 is rotatably mounted on the top of the fish fry storage box 3, and a handle 305 is fixedly mounted on the inner side of the top of the sealing cover 304. By gripping the handle 305, the sealing cover 304 can be easily opened, allowing staff to store and transport fish fry inside the fish fry storage box 3, thus facilitating staff operation.

[0034] Furthermore, an oxygen supply pipe 306 is movably installed through the top of the sealing cover 304, extending into the interior of the fry storage box 3. The input end of the oxygen supply pipe 306 is connected to an oxygen generator. Connecting plates 4 are fixedly installed axially between the fry storage boxes 3 on the top of the interior of the fry release and transportation body 1. The oxygen generator supplies oxygen to the water inside the fry storage box 3 through the oxygen supply pipe 306, preventing the fry from dying due to oxygen deficiency during transportation and storage in the water of the fry storage box 3.

[0035] Furthermore, a connector 401 is fixedly installed on the inner side of the connecting plate 4, and a drain outlet is provided between the inner side of the discharge port 301 and the connector 401. A guide plate 402 is fixedly installed on the bottom of the connector 401. Slide grooves 403 are provided on both sides of the connecting plate 4, and a slider 404 fixed to the fry storage box 3 is movably installed inside the slide grooves 403. The slider 404 slides inside the slide grooves 403, which facilitates the installation or removal of the fry storage box 3 between the connecting plates 4, thereby facilitating the cleaning operation of the fry storage box 3 by the staff. When the fry are discharged through the discharge port 301, the guide plate 402, which is made of soft silicone material, guides the fry into the pre-stored water, preventing the fry from hitting the inner wall of the drain outlet between the discharge port 301 and the connector 401 due to the impact of the water flow when the fry are discharged, thus avoiding the death of the fry due to the impact of the water flow. This improves the survival rate of the released fry.

[0036] Furthermore, the connecting plate 4 has storage slots 405 on both sides, and an L-shaped limiting rod 406 is rotatably installed inside the storage slots 405, located on top of the sealing cover 304. When the sealing cover 304 is closed, rotating the L-shaped limiting rod 406 so that one end is positioned on top of the sealing cover 304 limits its position, thus fixing the sealing cover 304 to the top of the fish fry storage box 3 for sealing and preventing fish fry from splashing out of the fish fry storage box 3 during transportation. When the sealing cover 304 needs to be opened, rotating the L-shaped limiting rod 406 retracts one end into the storage slot 405, making it easy to open the sealing cover 304 and allowing staff to add fish fry into the fish fry storage box 3 or clean the inside of the fish fry storage box 3.

[0037] Furthermore, the inner side of the base plate 2 has cavities 203 arranged axially. A fixing rod 204 is fixedly installed inside the cavity 203. A slide plate 205 is sleeved on the outer side of the fixing rod 204. A limiting block 206 extending to the outer side is fixedly installed on the top of the slide plate 205. A lever 207 extending to the outer side is fixedly installed on the bottom of the slide plate 205. A spring 208 located on one side of the slide plate 205 is sleeved on the outer side of the fixing rod 204. The top of the limiting block 206 is inclined. When the base plate 2 moves upward and closes, the elastic force of the spring 208 acts on the sliding plate 205, causing the sliding plate 205 to move the limiting block 206 inward. At this time, the bottom of the inner side of the limiting block 206 is located at the top of the bottom fixing plate of the fish fry release and transportation body 1, thus fixing the base plate 2 closed and preventing the fish fry release hose 108 from falling out of the storage cavity 109 during transportation and causing damage. When the staff needs to take out the fish fry release hose 108, they can move the lever 207 outward, causing the sliding plate 205 to squeeze the spring 208 and generate elastic force, which drives the limiting block 206 to move outward, thereby opening the base plate 2 and taking out the fish fry release hose 108, which is convenient for the staff to operate.

[0038] Working principle: First, the operator slides the slider 404 into the groove 403, thereby driving the fish fry storage box 3 to be installed between the connecting plates 4 on the top of the fish fry release and transport body 1. Then, by moving the lever 207 outward, the slide plate 205 moves outside the fixed rod 204, driving the limiting block 206 outward, thereby opening the limit of the bottom plate 2. At this time, the winding rod sleeve 202 moves downward outside the hanging rod 201, driving the bottom plate 2 to open, so that the operator can take out the fish fry release hose 108 from the storage cavity 109, fix it to the bottom of the release pipe 106 with bolts, and then extend the output port of the fish fry release hose 108 into the river water. Then, the output end of the electric telescopic rod 110 extends out, allowing the fish fry to be transported... The inlet 103 is connected to the outlet 104, so that the pre-stored water inside the water storage tank 101 is discharged into the outlet pre-storage chamber 102 for storage. When the water level inside the outlet pre-storage chamber 102 rises to the bottom of the outlet 301, the output end of the electric telescopic rod 110 retracts, causing the inlet 103 and the outlet 104 to be disconnected. Then, the sealing door 302 is pulled upward to open the outlet 301. The fish fry inside the fish fry storage box 3 are discharged into the outlet pre-storage chamber 102 through the outlet 301. Then, the valve 107 is opened to keep the fish fry inside the outlet pre-storage chamber 102 in the best condition and release them directly into the river through the outlet pipe 106 and the fish fry release hose 108. The above operation is performed one by one to release different kinds of fish fry.

[0039] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
