[0016] The present invention provides a boost push plate and an auxiliary balancing assembly. When the two boost push plates move toward each other, the auxiliary balancing assembly as a whole can limit the distance of the two boost push plates moving toward each other, thereby keeping the moving distance of the two boost push plates the same, that is, the water entering the two air storage chambers is the same, and the gas entering the main body of the live fish transport box is the same, so as to keep the main body of the live fish transport box as a whole steadily and vertically immersed in the water, avoiding complete sinking due to tilting.

[0017] The present invention is provided with a booster push plate and a linkage assembly. When the booster push plate moves toward the innermost side, the gas inside the gas storage chamber completely enters the live fish transport box body, and the live fish transport box body as a whole is completely submerged in water. At this time, the booster push plate will smoothly push the linkage assembly to drive the clamping blocks as a whole to move toward each other, so that the inner ends of the two clamping blocks are separated from the inner side of the cover plate, releasing the clamping and fixing effect on the cover plate as a whole. After that, the air pressure inside the live fish transport box body becomes greater, which can smoothly push the two cover plates to flip open, so that the fish can be smoothly released into the water.

[0022] The design of the spiral blade 402 can scrape off impurities in the water passing through the water inlet 401 by its rotation, avoiding clogging of the water inlet 401 so that water can smoothly pass through the water inlet 401 and slowly fill the air storage chamber 3.

[0023] like Figure 1 and Figure 2 As shown, the bottom of one end of the live fish transport box body 1 is fixedly connected to the oxygen delivery valve pipe 2, and the top of the air storage chamber 3 is fixedly connected to the exhaust pipe 11 located outside the boost push plate 403.

[0024] The above solution is adopted: by providing an oxygen delivery valve tube 2 and an exhaust pipe 11, through the design of the oxygen delivery valve tube 2, the operator can connect the pipe of the aerator with the oxygen delivery valve tube 2, so as to oxygenate the inside of the live fish transport box body 1 through it, and continuously supply the fish with oxygen, and the top of the exhaust pipe 11 is provided with a waterproof and breathable membrane, which can allow the gas outside the boost push plate 403 to be discharged smoothly through it, so that water can smoothly enter the interior of the air storage chamber 3.

[0025] like Figure 8 and Figure 9 As shown, the interior of the live fish transport box body 1 and the air storage chamber 3 is provided with an auxiliary balancing assembly 6 located on one side of the boost push plate 403. The auxiliary balancing assembly 6 includes a limit frame 601, a mounting rod 602, a rectangular slider 603, a return spring 604 and a first connecting arm 605; The limiting frame 601 is arranged in the middle of one end of the boost push plate 403, the mounting rod 602 is fixedly installed inside the live fish transport box body 1, and the rectangular slider 603 is movably installed on the top of the mounting rod 602.

[0026] The above solution is adopted: by providing a return spring 604, when the boost push plate 403 faces each other, it can push the two limit frames 601 to drive the first connecting arm 605 to deflect and push the rectangular slider 603 as a whole downward, while compressing the return spring 604. When the return spring 604 is released as a whole, it will push the rectangular slider 603 as a whole upward, so that the two first connecting arms 605 deflect and push the two limit frames 601 and the boost push plate 403 to move away from each other and reset.

[0027] like Figure 2 As shown, inflation valve tubes 7 are fixedly installed on both sides of the inner bottom end of the live fish transport box body 1, and the outer ends of the inflation valve tubes 7 are fixedly connected to the inner cavity of the air storage chamber 3.

[0028] The above solution is adopted: by providing an inflation valve tube 7, the operator can connect the inflation device to the outside through the inflation valve tube 7, and while the two booster push plates 403 move towards each other, the gas is filled into the interior of the gas storage chamber 3 through the auxiliary balancing assembly 6 for replenishment so as to facilitate subsequent sinking.

[0029] like Figure 5 and Figure 6 As shown, a cover assembly 8 is provided on the top of the live fish transport box body 1, and the cover assembly 8 includes a cover plate 801, a buckle groove 802, a clamping block 803 and a second connecting spring 804; The cover plate 801 is hinged to the top of the live fish transport box body 1, the buckle groove 802 is opened on the inner side of the top of the cover plate 801, the clamping block 803 is movably installed inside the live fish transport box body 1 and is located on the inner side of the cover plate 801, and the second connecting spring 804 is fixedly installed on the inner end of the clamping block 803.

[0030] The above solution is adopted: by providing the clamping blocks 803, when the outer ends of the two clamping blocks 803 are inserted into the inner ends of the cover plate 801 and fixed, the entire cover plate 801 can be clamped and fixed.

[0031] like Figure 6 As shown, the other end of the second connecting spring 804 is fixedly connected to the inner wall of the top of the live fish transport box body 1.

[0032] The above solution is adopted: by providing a second connecting spring 804, due to the elastic force of the second connecting spring 804, the two clamping blocks 803 can be pushed smoothly away from each other, so that the outer ends of the clamping blocks 803 are clamped inside the inner side of the cover plate 801.

[0033] like Figure 3 、 Figure 6 and Figure 7As shown, the interior of the live fish transport box body 1 is provided with a linkage assembly 9 located outside the clamping block 803, and the linkage assembly 9 includes a fixed rod 901, a push rod 902, a movable block 903 and a second connecting arm 904; The fixed rod 901 is fixedly installed at the bottom outside the clamping block 803, the pushing rod 902 is movably installed inside the live fish transport box body 1, and is located on the outside of the fixed rod 901, the movable block 903 is movably installed inside the live fish transport box body 1 and the air storage chamber 3, and is located on the outside of the pushing rod 902 and the air intake pipe 501, and the second connecting arm 904 is hinged between the outside of the pushing rod 902 and the top of the movable block 903.

[0034] The above solution is adopted: by providing a second connecting arm 904, when the boost push plate 403 moves toward each other, it can push the bottom inclined surface of the movable block 903 and drive the movable block 903 upward as a whole, which can push the second connecting arm 904 to deflect and push the push rod 902 to move toward each other.

[0035] like Figure 6 and Figure 7 As shown, the parts where the inner side of the push rod 902 and the outer side of the fixing rod 901 fit together are both designed with inclined surfaces.

[0036] The above solution is adopted: through the inclined surface design of the fitting surface of the push rod 902 and the fixed rod 901, when the push rod 902 moves toward each other, the inclined surface on the inner side of the push rod 902 slides and squeezes the inclined surface on the outer side of the fixed rod 901, thereby driving the fixed rod 901 and the clamping block 803 to move toward each other as a whole, so that the outer end of the clamping block 803 is separated from the inner side of the cover plate 801, thereby releasing the clamping fixation of the cover plate 801.

[0037] like Figure 3 As shown, the movable block 903 is elastically connected to the inner wall of the air storage chamber 3 through the power spring 10.

[0038] The above solution is adopted: by providing a power spring 10, the elastic force of the power spring 10 can assist in pushing the movable block 903 to reset downward as a whole.

[0039] The working principle and use process of the present invention: First, after the operator transports the Chinese sturgeon or rosy barramundi inside the live fish transport box body 1 from under the dam to above the dam, the operator needs to put the entire live fish transport box body 1 into the water above the dam. At this time, water will enter through the water inlet hole 401 at the bottom of the outer side of the air storage chamber 3, and the water flow will drive the spiral blade 402 to rotate as a whole to scrape away impurities, so that water slowly enters the inside of the air storage chamber 3 and the outside of the boost push plate 403 through the water inlet hole 401. At this time, the gas outside the boost push plate 403 will be discharged through the exhaust pipe 11.

[0040] When the two boost push plates 403 are pushed by water and move toward each other, the two limit frames 601 will move toward each other synchronously as a whole, and then the two first connecting arms 605 of the same size will deflect and push the rectangular slider 603 to slide downward along the surface of the mounting rod 602 as a whole, thereby limiting the moving distance of the two boost push plates 403, so that the two boost push plates 403 move a corresponding distance to allow the water to enter the outside of the boost push plates 403 at the same time, and the push can keep the boost push plates 403 pushing the same gas on the inside into the air intake pipe 501, and then push the one-way valve column 502 to move inward until a gap is created with the inner cavity of the air intake pipe 501, so that the gas can smoothly enter the interior of the live fish transport box body 1 for pressurization, and finally the live fish transport box body 1 as a whole is steadily and vertically submerged in the water, and the fish can slowly adapt to the pressure change without slowly sinking.

[0041] Afterwards, when the two booster push plates 403 push the internal gas of the air storage chamber 3 towards each other and completely enter the live fish transport box body 1, so that the live fish transport box body 1 is completely submerged in the water, the booster push plates 403 can be moved to the innermost side of the air storage chamber 3, and will push the inclined surface at the bottom of the movable block 903, thereby driving the movable blocks 903 on both sides to move upward synchronously as a whole, so that the second connecting arm 904 deflects and pushes the two push rods 902 to move towards each other, and then the inclined surface inside the push rod 902 will slide along the inclined surface outside the fixed rod 901, thereby smoothly squeezing and pushing the two clamping blocks 803 as a whole to move towards each other, until one end of the clamping block 803 is completely separated from the inside of the cover plate 801, and the clamping and fixing effect of the cover plate 801 can be released. Finally, the air pressure inside the live fish transport box body 1 increases, pushing the two cover plates 801 to flip open, so that the fish can be smoothly released into the water.
