For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] See Figures 1 to 3A device for de-adhesion of fertilized eggs of the giant spiny loach includes an incubator 100, a first frame 300, and a second frame 400. The incubator 100 has an incubation chamber 101, and a flushing pipe is installed at the bottom of the incubator 100, with the output end of the flushing pipe facing upward and built into the incubation chamber 101. Two first guide rails 200 and two second guide rails 210 are arranged above the incubator 100, with one end of the second guide rail 210 connected to the first guide rail 200 via a fixing rod 220. The first frame 300 is movably disposed between the two first guide rails 200, and a temporary storage box 310 for placing fertilized eggs is rotatably provided on the first frame 300. The temporary storage box 310 has a stirring assembly inside, and a first vertical block 311 is connected to the outer wall of the temporary storage box 310. The second frame 400 is movably disposed between the two first guide rails 200. Between the second guide rails 210, the second frame 400 is provided with a second vertical block 410. A first linkage mechanism is provided between the second vertical block 410 and the first vertical block 311. The first linkage mechanism is used to lock or unlock the connection between the second vertical block 410 and the first vertical block 311. A second linkage mechanism is provided between the second frame 400 and the fixed rod 220. The second linkage mechanism is used to lock or unlock the connection between the second frame 400 and the fixed rod 220. During the process of the first frame 300 moving to the second frame 400, the second vertical block 410 drives the first vertical block 311 to rotate so as to drive the temporary storage box 310 to flip and tilt the fertilized eggs. The first linkage mechanism is in the locked state. When the first frame 300 continues to move, the second linkage mechanism switches from the locked state to the unlocked state.

[0032] In the initial state of the above-described spiny loach fertilized egg de-adhesion device, the second linkage mechanism locks the connection between the second frame 400 and the fixed rod 220. The temporary storage box 310 is located on one side of the second frame 400 and is placed vertically, allowing people to place the artificially collected spiny loach fertilized eggs along with clean water into the temporary storage box 310. The pre-weighted de-adhesion liquid is then slowly poured into the temporary storage box 310. Finally, the stirring component is run to stir the fertilized eggs clockwise for 3 to 5 minutes, thereby completing the de-adhesion step of the fertilized eggs. After the fertilized eggs have debonded, the first frame 300 is moved so that the second vertical block 410 abuts against the first vertical block 311, causing the first vertical block 311 to deflect the temporary storage box 310. At the same time, the first linkage mechanism locks the connection between the second vertical block 410 and the first vertical block 311, thereby maintaining the deflection angle of the temporary storage box 310. Then, the first frame 300 is moved again, and the second linkage mechanism switches from the locked state to the unlocked state, allowing the second frame 400 to move synchronously with the first frame 300. Finally, the first frame 300 is moved again, allowing the fertilized eggs in the temporary storage box 310 to be gradually poured into the incubator 100 along the moving path of the temporary storage box 310. This ensures that the debonded fertilized eggs are evenly scattered in the incubator 100, which is beneficial to improving the subsequent hatching effect of the fertilized eggs. The above structure can standardize the steps of detaching and pouring fertilized eggs of the giant spiny loach, thereby reducing the differences caused by different personnel performing fish egg incubation operations and helping to ensure the uniformity of each fertilized egg being scattered in the incubator 100.

[0033] It is understood that in some embodiments, the first guide rail 200 may also be a lead screw, and the first frame 300 is mounted on the corresponding lead screw via a slider, with the lead screw rotating via a motor. After the fertilized egg detaches, the motor can be used to drive the lead screw to rotate, thereby improving the automation level of the movement of the first frame 300 and also facilitating the control of the movement stroke of the first frame 300.

[0034] See Figures 1 to 3Furthermore, the first vertical block 311 is provided with a sliding groove 312, and the upper end of the second vertical block 410 is horizontally provided with a pushing block 411. The pushing block 411 slides in cooperation with the sliding groove 312. The first linkage mechanism includes a first latching member 420 elastically provided on the pushing block 411, and the sliding groove 312 is provided with a first latching hole 314 that is inserted and cooperated with the first latching member 420 in the horizontal direction. Specifically, when the first frame 300 moves to the position of the second frame 400, the push block 411 is inserted into the slide groove 312 to drive the first vertical block 311 to deflect to a horizontal state. At the same time, the first fastener 420 is built into the slide groove 312 and is in an elastic deformation state. Then, the first frame 300 continues to move, so that the first fastener 420 moves along the slide groove 312 to the position of the first locking hole 314. Finally, the first fastener 420 restores its deformation and is inserted into the first locking hole 314, thereby connecting the first vertical block 311 and the second vertical block 410 into one unit, which is beneficial for the first frame 300 to drive the second frame 400 to move. It is understandable that the slide 312 has a stepped structure, including a large opening section, a small opening section, and an inclined section connecting the large opening section and the small opening section. The first locking hole 314 is located in the small opening section, so that the pushing block 411 and the first locking member 420 can be synchronously built into the large opening section, avoiding the phenomenon that the first locking member 420 is externally placed in the slide 312. The first locking member 420 undergoes elastic deformation in the inclined section. The first locking member 420 maintains elastic deformation and moves in the small opening section. Finally, the first locking member 420 returns to its original deformation at the position of the first locking hole 314.

[0035] See Figures 1 to 3 Furthermore, the first latching member 420 includes an L-shaped rod 421 connected to the push block 411. One end of the L-shaped rod 421 is connected to a protrusion 422. The protrusion 422 includes a first plane and a second plane arranged parallel to each other. The first plane faces the slide groove 312, and an inclined surface connects the first plane and the second plane. The side of the inclined surface connected to the first plane is offset away from the push block 411. Specifically, the L-shaped rod 421 is arranged such that there is a gap between the protrusion 422 and the push block 411, allowing the L-shaped rod 421 to undergo partial deformation under force. The inclined surface is offset away from the first plane on the side that connects to the first plane, making the area of ​​the first plane larger than that of the second plane. This results in a difference in the area of ​​the two protruding from the first locking hole 314. When the first frame 300 moves toward the side closer to the incubator 100, the first plane makes it difficult for the first latch 420 to disengage from the first locking hole 314, which helps to improve the stability of the first linkage mechanism in the locked state. When the first frame 300 moves toward the side away from the incubator 100, the arrangement of the first plane and the inclined surface makes it easier for the first latch 420 to disengage from the first locking hole 314, which helps to reduce the difficulty and force required for people to switch the first linkage mechanism from the locked state to the unlocked state.

[0036] See Figure 1 Furthermore, the temporary storage box 310 is provided with a conical cavity 313, and the stirring assembly is located at the large port of the conical cavity 313. When the temporary storage box 310 is deflected, the large port of the conical cavity 313 is close to the second frame 400. Specifically, when the second vertical block 410 drives the first vertical block 311 to a horizontal state, the large port of the conical cavity 313 faces the side of the incubator 100, so that the inner wall of the conical cavity 313 can form an inclined surface that facilitates the pouring of fertilized eggs, which is beneficial for the fertilized eggs to be poured out of the temporary storage box 310.

[0037] See Figure 1 and Figure 3 Furthermore, the stirring assembly includes an annular ring 320 rotatably mounted in the storage tank 310. The annular ring 320 is detachably fitted with two crossbars 321 in a cross shape. Multiple feathers are mounted on the lower surface of the crossbars 321, and these feathers are embedded in a conical cavity 313 to agitate the fertilized eggs. Specifically, artificially collected fertilized eggs of the giant spiny loach are placed in the storage tank 310 along with clean water. A desiccant solution is slowly poured into the storage tank 310, and the multiple feathers are rotated clockwise to agitate the fertilized eggs for 3 to 5 minutes, facilitating the removal of external mucus from the fertilized eggs. The crossbars 321 can be made of sponge material, with one end of each feather inserted into the sponge and fixed with adhesive. The annular ring 320 has mounting grooves, and one end of each crossbar 321 is inserted into these grooves, simplifying the installation of the crossbars 321 and the feathers. The upper part of the temporary storage box 310 is provided with an annular groove, and the lower part of the annular ring 320 is provided with an annular protrusion. The annular protrusion and the annular groove are concentric. The annular protrusion is inserted into the annular groove, so that the annular ring 320 can rotate relative to the temporary storage box 310.

[0038] See Figure 1 and Figure 3 Furthermore, the second frame 400 is provided with an egg-laying box 430 located between the two first guide rails 200. The egg-laying box 430 has an upward-facing cavity 431, which is used to receive fertilized eggs poured from the temporary storage box 310. Below the egg-laying box 430, there are multiple output pipes 432 connected to the cavity 431. The output pipes 432 are used to output fertilized eggs one by one, so that the fish eggs in the temporary storage box 310 can be poured into the cavity 431. During the movement of the temporary storage box 310, the fertilized eggs can be output one by one through the multiple output pipes 432, which is conducive to the fertilized eggs being evenly scattered on the path of the first guide rail 200 into the incubator 100, thus achieving the effect of even egg distribution.

[0039] See Figure 3Furthermore, the fixing rod 220 is provided with a mounting block 221, which has a groove. A plug-in rod 222 is provided on one side of the egg-laying box 430. The second linkage mechanism includes a second latching member located at one end of the plug-in rod 222. The side wall of the groove has a second locking hole that engages with the second latching member in a horizontal direction, thereby utilizing the engagement between the second latching member and the second locking hole to lock and unlock the second linkage mechanism. The structure of the second latching member is similar to that of the first latching member 420, and will not be described in detail here.

[0040] See Figure 1 and Figure 3 Furthermore, the first frame 300 includes two parallel movable plates 301, the lower ends of which are slidably mounted on the first guide rail 200. The temporary storage box 310 is connected to the two movable plates 301 via a pivot 302. One end of the first vertical block 311 is connected to the pivot 302 so that the first vertical block 311 and the temporary storage box 310 move synchronously, which is beneficial for the second vertical block 410 to drive the temporary storage box 310 to rotate via the first vertical block 311.

[0041] This invention also discloses a method for de-adhesion of fertilized eggs of the giant spiny loach using any of the above-mentioned technical solutions, comprising the following steps:

[0042] Step 1: Fertilized eggs of giant spiny loach were obtained by artificial insemination, and a desliming solution composed of sodium chloride solution and talc was prepared;

[0043] Step 2: Place the artificially collected fertilized eggs of the giant spiny loach along with clean water into the temporary storage tank 310, and slowly pour the desiccant into the temporary storage tank 310. Run the stirring component to stir the fertilized eggs clockwise for 3 to 5 minutes.

[0044] Step 3: Move the first frame 300 toward the side closer to the incubator 100. The first linkage mechanism locks the engagement of the second vertical block 410 and the first vertical block 311, and the second linkage mechanism unlocks the engagement of the first frame 300 and the second frame 400. Continue to move the first frame 300. The temporary storage box 310 remains in a deflected state to evenly scatter the fertilized eggs into the incubator 100.

[0045] Step 4: Move the first frame 300 in the reverse direction, the second linkage mechanism locks the cooperation between the first frame 300 and the second frame 400, the first linkage mechanism unlocks the cooperation between the second vertical block 410 and the first vertical block 311, and the temporary storage box 310 rotates to be placed vertically.

[0046] According to an embodiment of the present invention, a pipeline leak repair method has at least the following beneficial effects: through the above steps, the detachment and pouring of fertilized eggs can be standardized, thereby evenly distributing the fertilized eggs in the incubator 100.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
