DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] See also Figure 1-Figure 9A multi-type fish fry releasing device comprises a fish fry releasing transport body 1 and a bottom plate 2 movably installed at the bottom of the fish fry releasing transport body 1, the top of the outer side of the fish fry releasing transport body 1 is rotatably connected with a water storage tank body 101 through a sealing ring, a release pre-storage chamber 102 is arranged inside the fish fry releasing transport body 1, input holes 103 are evenly distributed along the axis inside the fish fry releasing transport body 1, drain holes 104 connected with the input holes 103 are evenly distributed along the axis inside the bottom of the water storage tank body 101, a partition 105 is fixedly installed inside the release pre-storage chamber 102, the top of the partition 105 is inclined toward the axis, and the bottom of the partition 105 is fixed. A discharge pipe 106 is fixedly installed which runs 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 storage chamber 109 is arranged at the bottom of the inside of the fish fry release and transport body 1, an electric telescopic rod 110 which is rotatably connected to the top of the water storage tank 101 is rotatably installed on one side of the top of the fish fry release and transport body 1, the bottom plate 2 is movably installed at the opening at the bottom of the storage chamber 109, a suspension rod 201 is fixedly installed along the axis at the bottom of the partition 105, and a winding rod sleeve 202 fixed to the top of the bottom plate 2 is sleeved on the outer side of the suspension rod 201.

[0027] Through the above-mentioned structural arrangement, the device for releasing multiple types of fry can transport multiple types of fry to natural waters for release by storing multiple types of fry in the fry storage box 3 respectively, and then the output end of the electric telescopic rod 110 is contracted to drive the water storage box 101 to rotate so that the input hole 103 and the water discharge hole 104 are connected through and connected, and then the water storage box 101 discharges water into the discharge pre-storage chamber 102 through the input hole 103 and the water discharge hole 104, so that the discharge pre-storage chamber 102 The interior of the fry storage box 3 is filled with pre-stored water, the water level is raised to the bottom of the discharge port, the output end of the electric telescopic rod 110 is extended to drive the water storage box 101 to rotate, so that the input hole 103 and the water discharge hole 104 are staggered, the drain port is closed, and then the fry in the fry storage box 3 are discharged into the pre-stored water in the discharge pre-storage chamber 102, avoiding the situation that the fry are in poor spirits due to the impact force when they are discharged from a high place, and then the output port of the fry discharge hose 108 is placed in the river water, and then the valve 107 is opened. , so that the fry in the discharge pre-storage chamber 102 is directly discharged into the river water through the discharge pipe 106 and the fry discharge hose 108 inside the soft fry discharge hose 108, thereby avoiding the death of the fry due to collision during the discharge process, so that different types of fry can be discharged intermittently one by one, thereby improving the survival rate of the fry release. After the fry release is completed, the fry discharge hose 108 is removed from the bottom of the discharge pipe 106, and then the fry discharge hose 108 is wrapped around the fry discharge hose 108. On the outside of the winding rod sleeve 202, the winding rod sleeve 202 is moved upward on the outside of the suspension rod 201, so that the suspension rod 201 is contracted to the inside of the winding rod sleeve 202, thereby driving the bottom plate 2 to move upward, and the fry release hose 108 is stored in the storage cavity 109, so as to avoid the fry release hose 108 being installed at the bottom of the release pipe 106 and being damaged during transportation, thereby causing the fry to leak out through the damaged part to the ground during release and cause the death of the fry.

[0028] Furthermore, a support ring 111 is fixedly installed inside the fry release transport body 1, the fry storage box 3 is located at the top of the support ring 111, a discharge port 301 is opened inside the fry storage box 3, and a sealing door 302 is movably installed inside the discharge port 301 through a sealing strip. The fry storage box 3 can be supported by the support ring 111, so that the fry storage box 3 can be installed at the top inside the fry release transport body 1 for transporting and storing fry, and by opening the sealing door 302, different kinds of fry inside each fry storage box 3 can be intermittently released one by one.

[0029] Furthermore, water inlets 112 are fixedly installed on both sides of the top of the water storage tank 101, and a water stop plate 303 is fixedly installed on the bottom of the inner side of the sealing door 302. The water inlet 112 facilitates the replenishment of pre-stored water inside the water storage tank 101, so that the pre-stored water can be continuously injected into the discharge pre-storage chamber 102 to shorten the discharge height difference, thereby ensuring that the fry can directly fall into the pre-stored water inside the discharge pre-storage chamber 102 after being discharged from the discharge port 301 to move, thereby improving the survival rate of the fry during discharge. When the sealing door 302 is closed, the water stop plate 303 is located on the inner side of the fry storage box 3 for water-stopping protection to prevent the fry storage box 3 from leaking and causing the fry to die.

[0030] Furthermore, a sealing cover 304 is rotatably mounted on the top of the fry storage box 3, and a handle 305 is fixedly mounted on the inner side of the top of the sealing cover 304. The sealing cover 304 can be opened conveniently by holding the handle 305, so that the staff can store and transport the fry inside the fry storage box 3, which is convenient for the staff to operate.

[0031] Furthermore, an oxygen supply pipe 306 extending to the inside of the fry storage box 3 is movably installed through the top of the sealing cover 304, and the input end of the oxygen supply pipe 306 is connected to the oxygen generator, and a connecting plate 4 located between the fry storage boxes 3 is fixedly installed in an axial distribution at the top of the inside of the fry release transport body 1. The oxygen generator inputs oxygen into the water inside the fry storage box 3 through the oxygen supply pipe 306, so that the fry will not die due to lack of oxygen when they are transported and stored in the water of the fry storage box 3.

[0032] Further, a connector 401 is fixedly installed on the inner side of the connecting plate 4, and a discharge port 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 connecting plate 401, and a slide groove 403 is 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 groove 403. Among them, the slider 404 slides inside the slide groove 403, so that the fry storage box 3 is conveniently installed or removed between the connecting plates 4, thereby facilitating the staff to clean the fry storage box 3. When the fry is discharged through the discharge port 301, since the guide plate 402 is a soft silicone material, the guide plate 402 guides the fry to the pre-stored water, so as to avoid the fry from hitting the inner wall of the discharge port between the discharge port 301 and the connecting member 401 due to the impact of the water flow when the fry is discharged, resulting in the death of the fry, thereby improving the survival rate of the fry.

[0033] Furthermore, receiving grooves 405 are provided on both sides of the connecting plate 4, and an L-shaped limiting rod 406 located at the top of the sealing cover 304 is rotatably installed inside the storing groove 405. When the sealing cover 304 is closed, the L-shaped limiting rod 406 is rotated so that one end of the limiting rod is located at the top of the sealing cover 304 to limit the sealing cover 304, so that the sealing cover 304 is fixed on the top of the fry storage box 3 to seal, so as to prevent the fry from splashing out from the inside of the fry storage box 3 during transportation. When the sealing cover 304 needs to be opened, the L-shaped limiting rod 406 is rotated to store one end of the limiting rod in the storing groove 405, so as to facilitate the opening of the sealing cover 304, and facilitate the staff to add the fry into the inside of the fry storage box 3 or clean the inside of the fry storage box 3.

[0034] Furthermore, a cavity 203 is axially distributed inside the inner side of the bottom plate 2, 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 limit block 206 extending to the outside is fixedly installed on the top of the slide plate 205, a lever 207 extending to the outside 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, and the top of the limit block 206 is inclined. Among them, when the bottom plate 2 moves upward and closes, the elastic force of the spring 208 acts on the slide plate 205, so that the slide plate 205 drives the limit block 206 to move inward. At this time, the bottom of the inner side of the limit block 206 is located at the top of the bottom fixed plate of the fry release transport body 1 for limiting, so that the bottom plate 2 is fixed and closed, and the fry release hose 108 is prevented from falling out of the storage cavity 109 during transportation and causing damage. When the staff needs to take out the fry release hose 108, they move the lever 207 outward, so that the slide plate 205 squeezes the spring 208 to generate elastic force, driving the limit block 206 to move outward, so that the bottom plate 2 can be opened to take out the fry release hose 108, which is convenient for the staff to operate.

[0035] Working principle: First, the staff slides the slider 404 into the interior of the slide groove 403, thereby driving the fry storage box 3 to be installed between the connecting plates 4 on the top of the fry release transport body 1, and then moves the lever 207 outward, so that the slide plate 205 moves on the outside of the fixed rod 204, driving the limit block 206 to move outward, so that the limit of the bottom plate 2 is opened, and at this time, the winding rod sleeve 202 moves downward on the outside of the suspension rod 201, driving the bottom plate 2 to open, so that the staff can take out the fry release hose 108 inside the storage chamber 109, fix it to the bottom of the release pipe 106 with bolts, and then extend the output port of the fry release hose 108 into the river water, and then extend the output end of the electric telescopic rod 110 to make the output The inlet hole 103 is connected with the drain hole 104, so that the pre-stored water inside the water storage box 101 is discharged into the discharge pre-storage chamber 102 for storage. When the water level inside the discharge pre-storage chamber 102 rises to the bottom of the discharge port 301, the output end of the electric telescopic rod 110 contracts, so that the input hole 103 and the drain hole 104 are misaligned and disconnected, and then the sealing door 302 is pulled upward to open the discharge port 301, and the fry inside the fry storage box 3 is discharged into the discharge pre-storage chamber 102 through the discharge port 301, and then the valve 107 is opened to keep the fry inside the discharge pre-storage chamber 102 in the best state and directly discharge it into the river through the discharge pipe 106 and the fry discharge hose 108. According to the above operation, different types of fry are released one by one.
