Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture, and particularly relates to a zebrafish three-dimensional aquaculture system and an installation structure of its aquaculture rack. Background Art

[0002] Many drugs entering clinical applications or clinical trials originate from zebrafish. However, so far, this main model animal for whole-animal chemical genetics and pharmacology research is little known;

[0003] At the same time, within the physiological relevant dose range, the response of zebrafish to drug molecules is highly consistent with that of humans. Gene editing technology combined with real-time high-resolution imaging can fully observe the molecular details of drug molecules in zebrafish disease models; it is very efficient and low-cost to use this for in vivo drug screening, pharmacological and efficacy evaluation, safety evaluation, and pharmacokinetics;

[0004] However, the existing zebrafish three-dimensional aquaculture devices have the following problems:

[0005] 1. Merchants usually place zebrafish of different sizes in different models of fish tanks, and then uniformly place and fix the aforementioned fish tanks through a customized three-dimensional aquaculture placement rack. However, due to the fixed model of the customized aquaculture placement rack, it is not only inconvenient for workers to carry in special environments, but also has problems such as inconvenient portability. At the same time, the overall aquaculture placement rack occupies a large area, resulting in an increase in the transportation cost of the manufacturer, that is, it is impossible to utilize the effective space to achieve a large number of transports;

[0006] 2. Since the sizes of zebrafish themselves are not fixed, and the sizes of zebrafish also change continuously during the aquaculture process, and at the same time, the depths of the fish tanks for storing zebrafish of different sizes will also be adjusted accordingly, the customized aquaculture placement rack restricts the scientific aquaculture of zebrafish to a certain extent. That is, on the one hand, it is not conducive to the healthy growth of zebrafish, and on the other hand, it affects the relevant data of zebrafish in later experiments, thereby causing immeasurable losses to the corresponding scientific research.

[0063] 2. The present invention drives the sliding blocks at both ends to move towards or away from each other through the adjusting rod, realizing the adjustment of the distance between the upper ends of the first rectangular frame and the second rectangular frame. At the same time, the height between the L-shaped seats on both sides and the base plate also changes accordingly, so as to adapt to the targeted adjustment of fish tanks with different lengths and heights, which is beneficial for the merchant to carry out diversified and scientific aquaculture of zebrafish, improving the survival rate of zebrafish and intermittently improving the research accuracy of zebrafish.

[0064] 3. The present invention allows the operator to rotate the No. 2 rotary valve in the secondary regulating unit, thereby forcing it to drive the connecting plate to move downward until the connecting plate conflicts with the L-shaped seat. In this process, by observing the positional relationship between the pointer and the scale line, the positions of fish tanks of different widths are fixed and limited in a targeted manner, thereby adapting to the growth of zebrafish in the breeding process and achieving more scientific breeding. The breeding rack with adjustable length, width and depth can not only avoid increasing the breeding cost of the breeding manufacturer, but also solve the problem of the limitation of traditional fixed breeding racks on the scientific breeding of zebrafish.

[0089] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0090] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used in this document are only for the purpose of explanation and do not represent the only implementation method.

[0091] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0092] A three-dimensional zebrafish breeding system and a breeding rack installation structure thereof, including a fish breeding circulation system, the fish breeding circulation system mainly includes three aspects: water circulation, biological filter and plant filter. At the same time, water circulation is the core of the fish breeding circulation system, and the breeding rack is an important component to realize water circulation.

[0093] Reference Figure 1 and Figure 4 It can be seen that the breeding rack includes a base plate 1, and the upper end surface of the base plate 1 is evenly provided with convex grooves 11 along its length direction, the number is six, and two adjacent convex grooves 11 form a group, and the upper end surface of the base plate 1 is provided with a rectangular T-shaped frame 12, and the base plate 1 directly below each T-shaped frame 12 is provided with a symmetrically distributed connecting groove 13, and a convex platform 14 is installed in the connecting groove 13, and a first-level adjustment unit 2 is provided directly above each group of convex grooves 11;

[0094] Reference Figure 1 , Figure 4 and Figure 5 It can be seen that the primary adjustment unit 2 includes: a 匚-shaped seat 21, which is movably mounted on the upper end surface of the base plate 1 directly above each group of convex grooves 11, and the horizontal section of the 匚-shaped seat 21 is provided with symmetrically distributed through grooves 22, and the through grooves 22 correspond to the convex grooves 11 in one-to-one position; an adjustment rod 23, which is rotatably mounted between the vertical sections of the 匚-shaped seat 21, and the outer walls of both ends of the adjustment rod 23 are provided with spiral grooves with opposite rotation directions; two sliding blocks 24, which are threadedly mounted on both ends of the outer wall of the adjustment rod 23; a rectangular frame 25, which is rotatably mounted on one side of the sliding block 24; The second rectangular frame 26 is rotatably mounted on the sliding block 24 at the relative position, and the second rectangular frame 26 and the first rectangular frame 25 are both rectangular structures composed of two plates and two shafts. An I-shaped shaft 27 is rotatably mounted in the middle position of the second rectangular frame 26 and the first rectangular frame 25, and both sides of the outer wall of the shaft section of the second rectangular frame 26 and the first rectangular frame 25 are provided with annular grooves 28; an L-shaped seat 29 is detachably mounted on the outer wall of the shaft end of the second rectangular frame 26 and the first rectangular frame 25 away from the sliding block 24, and the horizontal section of the L-shaped seat 29 is parallel to the base plate 1;

[0095] Reference Figure 1 , Figure 3 and Figure 9It can be seen that a lifting unit 6 is provided on the vertical section of the T-shaped frame 12. The lifting unit 6 includes: a mountain-shaped plate 61, which is slidably installed inside each vertical section of the T-shaped frame 12; a rack 62, which is fixedly installed at the middle position of the mountain-shaped plate 61; a gear 63, which is installed above the vertical section of the T-shaped frame 12 through a rotating shaft and meshes with the rack 62; a card seat 64, which is movably clamped in the width direction of the base plate 1 and at the middle position of the opposite surfaces of the T-shaped frames 12 facing each other; a strip-shaped plate 65, which is clamped and installed between two opposite card seats 64; and L-shaped brackets 66, which are symmetrically distributed on the end surfaces of each vertical section of the T-shaped frame 12 above and away from the middle position of the base plate 1.

[0096] When the operator starts to assemble the aquaculture placement rack:

[0097] First, place each T-shaped frame 12 at the four corners of the base plate 1 (and make the holes on the horizontal section of the T-shaped frame 12 itself directly opposite to the communication groove 13), and then movably clamp the C-shaped seat 21 directly above the convex groove 11 at the corresponding position;

[0098] Then, manually rotate the gear 63 (in specific implementation, the rotation of the gear 63 shaft can be driven by an external clamping part). Under the meshing action of the rack 62 and the gear 63, the mountain-shaped plate moves upward to a specified position (specifically, it can be based on the number of turns of the gear 63, and the rising height of each mountain-shaped plate 61). The position of the strip-shaped plate 65 is limited by the card seat 64 (the strip-shaped plate 65 can be used to install an existing water return tank bracket, which is convenient for laying the water circulation pipeline and wiring), and the position of the raised mountain-shaped plate 61 is fixed accordingly through the reserved L-shaped brackets 66 (for specific implementation, refer to the subsequent principle description);

[0099] Finally, by rotating (forward and reverse) the adjusting rod 23, the two sliding blocks 24 move towards or away from each other under the action of the threaded grooves with different rotation directions. At the same time, the first rectangular frame 25 and the second rectangular frame 26 are synchronously telescoped through the I-shaped shaft 27, thereby adjusting the distance between the two L-shaped seats 29 and the height between the horizontal section of the L-shaped seat 29 and the base plate 1 (that is, to adapt to fish tanks of different lengths and heights), which is beneficial for merchants to carry out diversified aquaculture, enables zebrafish to obtain a more suitable living space, and indirectly improves scientific research results;

[0100] Through the setting of the sliding groove 36, the connection stability between the plate-shaped structure and the shaft-shaped structure of the first rectangular frame 25 and the second rectangular frame 26 is improved, thereby preventing the fish tank between the L-shaped seats 29 from tipping over, and thus avoiding unnecessary waste.

[0101] Refer to Figure 6 、 Figure 7 and Figure 8It can be seen that a first-level limiting unit 3 is arranged below the first-level adjusting unit 2. The first-level limiting unit 3 includes: a movable pipe 31, symmetrically penetrating and distributed in the middle position of each sliding block 24, and corresponding to the through groove 22 one by one; a clamping block 32, symmetrically and fixedly installed on the outer wall of the movable pipe 31, and the clamping block 32 is slidably installed in cooperation with the sliding block 24; a positioning shaft 33, slidably installed in the inner wall of the movable pipe 31, and a threaded groove is opened on the outer wall of the upper end of the positioning shaft 33; a first rotary valve 34, threadedly installed on the upper end of the positioning shaft 33, and the lower end surface of the first rotary valve 34 is in contact with the upper end surface of the movable pipe 31; a cross plate 35, fixedly installed at the lower end of the positioning shaft 33 and in movable contact with the base plate 1. Four sliding grooves 36 are evenly opened on the upper end surface of the cross plate 35 along the circumference of the positioning shaft 33; a moving plate 37, slidably installed between each sliding groove 36 and the cross plate 35; a resisting plate 38, fixedly installed at the middle position of the end surface of the moving plate 37 away from the positioning shaft 33.

[0102] Referring to Figure 7 and Figure 8 It can be seen that a gear plate 311 is installed on the outer wall of the lower end of the movable pipe 31, a convex pipe 312 slidably installed in cooperation with the positioning shaft 33 is installed at the lower end of the movable pipe 31, a snap ring 313 is installed on the outer wall of the lower end of the positioning shaft 33, a return spring 314 is sleeved between the snap ring 313 and the convex pipe 312. Vertical plates 315 are installed at the middle positions on both sides of each sliding groove 36. Triangular blocks 316 are installed on both sides of the middle position of the end surface of the moving plate 37 away from the positioning shaft 33. Cranks 317 rotatably installed in cooperation with the moving plate 37 are evenly rotatably installed on the outer wall of the middle position of the convex pipe 312 along its circumference through ear seats.

[0103] Referring to Figure 7 and Figure 8 It can be seen that four guiding plates 3151 are evenly installed on the end surface of each vertical plate 315 close to the sliding groove 36 from top to bottom, and two guiding plates 3151 are in a group. A wedge block 3152 is slidably installed at the middle position of each group of guiding plates 3151. The wedge block 3152 is composed of a triangular end and a shaft end. A first convex block 3153 is installed at one end of the upper wedge block 3152 away from the guiding plate 3151, a second convex block 3154 is installed at one end of the lower wedge block 3152 away from the guiding plate 3151. A round gasket 3155 slidably installed in cooperation with the outer wall of the shaft end of the wedge block 3152 is installed on the guiding plate 3151 close to the first convex block 3153 and the second convex block 3154. A telescopic spring 3156 is sleeved between the round gasket 3155 and the first convex block 3153 or the second convex block 3154. Tooth-shaped grooves 3157 are opened on the end surfaces of the first convex block 3153 and the second convex block 3154 away from the round gasket 3155.

[0104] Before installing the first-level limit unit 3, first pass the positioning shaft 33 with the first rotary valve 34 in the initial state through the hole reserved by the sliding block 24 itself, and then assemble the first rotary valve 34 with the positioning shaft 33;

[0105] When the adjusting rod 23 completes the adjustment of the position of the sliding block 24 (the threaded fit between the sliding block 24 and the adjusting rod 23 may cause shaking between the two after long-term use), then by rotating (forward) the first rotary valve 34, the movable tube 31 moves vertically downward under the guiding action of the clamping block 32 and forces the convex tube 312 to move towards the cross plate 35. At the same time, the crank 317 drives the moving plate 37 to move in the chute 36 until the contact plate 38 contacts and presses against the side wall of the convex groove 11, thereby initially realizing the fixed limit of the position of the sliding block 24, which is beneficial to improving the stability and firmness of the sliding block 24 after the position is adjusted by the adjusting rod 23;

[0106] Finally, through the mutual extrusion of the triangular block 316 that moves synchronously with the moving plate 37 and the wedge block 3152, the first convex block 3153 and the second convex block 3154 contact and press against the inner walls of the upper and lower sides of the convex groove 11 under the action of their respective wedge blocks 3152 (the moving stability of the wedge block 3152 is strengthened by the guiding plate 3151). And when the first rotary valve 34 is reversed, the convex tube 312 exerts a reverse force on the snap ring 313 under the elastic force of the return spring 314, so as to return to the initial position. Similarly, at this time, the wedge block 3152 returns to the initial position under the elastic force of the telescopic spring 3156), thereby further improving the firmness of the first-level limit unit 3 in the convex groove 11, and at the same time avoiding the limitations of the fixed limit between the traditional bolt and the screw hole, that is, the first-level limit unit 3 in this product can perform targeted and effective fixed limit on the adjusted position of the sliding block 24 at different positions, and the first-level limit unit 3 in this product is both flexible and diverse, and is also convenient to carry and assemble;

[0107] Through the contact extrusion between the gear plate 311 and the C-shaped seat 21 (the gear plate moves downward with the movable tube 31 until it contacts and presses against the C-shaped seat 21), the stability of the C-shaped seat 21 after snap-in installation is further improved (that is, no shaking occurs), ensuring the horizontality of the fish tank between the L-shaped seats 29.

[0108] Refer to Figure 4 and Figure 5It can be known that a prestress unit 4 is arranged at the middle position of the first-level adjustment unit 2. The prestress unit 4 includes: a shaft sleeve 41, with a quantity of two, symmetrically installed through threads at both ends of the outer wall of the I-shaped shaft 27; a limit plate 42, symmetrically fixedly installed on the outer wall of each shaft sleeve 41; a positioning column 43, evenly distributed along the circumferential direction of the I-shaped shaft 27 at one end of the shaft sleeve 41 far from the middle position of the I-shaped shaft 27, and through holes 44 corresponding to the positioning columns 43 one by one are opened at the middle position of the plate section of the second rectangular frame 26; a steering wheel 45, rotatably installed at the middle position of the outer wall of the I-shaped shaft 27 and simultaneously movably clamped with the limit plates 42 on both sides; and a handle 46, evenly distributed along the circumferential direction of the I-shaped shaft 27 on the outer wall of the steering wheel 45.

[0109] After the adjusting rod 23 completes the position adjustment of the sliding block 24:

[0110] The operator rotates the handle 46, and the rotated steering wheel 45 drives the shaft sleeve 41 to rotate through the limit plate 42. At the same time, the shaft sleeve 41 rotates and moves away from the center position of the I-shaped shaft 27 under the action of the thread grooves on both sides of the I-shaped shaft 27 until the positioning column 43 is engaged in the through hole 44, and at this time, the shaft sleeves 41 at both ends respectively press against the two plate-like structures on both sides of the second rectangular frame 26, thereby enhancing the mutual acting force between the first rectangular frame 25 and the second rectangular frame 26 and preventing the first rectangular frame 25 and the second rectangular frame 26 from shaking after long-term work (the fish in the fish tank are swimming).

[0111] Refer to Figure 9 、 Figure 10 and Figure 11 It can be known that a second-level limiting unit 5 is arranged below the T-shaped frame 12. The second-level limiting unit 5 includes: a convex pin 51, symmetrically installed in a penetrating manner at both sides of the horizontal section of each T-shaped frame 12 and corresponding to the communication groove 13 one by one; a telescopic sleeve rod 52, slidably installed at the middle position of the lower end face of the convex pin 51; an anti-collision pad 53, fixedly installed on the lower end face of the telescopic sleeve rod 52; a pin shaft 54, fixedly installed at the middle position of the lower end face of the anti-collision pad 53; a hook 55, rotatably installed on the outer wall of the middle position of the telescopic sleeve rod 52 through an ear seat distributed along the circumferential direction of the convex pin 51; a torsion spring 56, sleeved on both ends of the outer wall of the shaft end of the hook 55; a straight rod 57, symmetrically distributed on both sides of each convex pin 51 and clamped and installed with the bracket of the T-shaped frame 12, and its shape is a convex structure; a circular ring 58, fixedly installed on the outer wall of the lower end of the straight rod 57; and a telescopic sleeve 59, slidably installed on the outer wall of the upper end of the straight rod 57 and located above the circular ring 58.

[0112] Refer to Figure 11 It can be known that a second rotary valve 571 is installed on the outer thread of the upper end of the straight rod 57, and a rectangular plate 572 matched with the convex pin 51 is installed on the outer wall of the lower end of the telescopic sleeve rod 52.

[0113] When the T-shaped bracket 12 is directly above the communication slot 13 at the corresponding position:

[0114] The operator directly presses down the convex pin 51. At this time, the telescopic sleeve rod 52 drives the anti-collision pad 53 and the pin shaft 54 to move towards the convex platform 14 after being stressed, until the anti-collision pad 53 contacts the upper end surface of the convex platform 14 (and the pin shaft 54 just enters the reserved hole in the middle of the convex platform 14). At the same time, through the telescopic property of the telescopic sleeve rod 52 itself, the force suddenly applied to the telescopic sleeve rod 52 by the convex pin 51 is effectively buffered. After that, when the hook 55 contacts the upper end of the convex platform 14, the torsion spring 56 changes its rotation angle until the bottom end of the hook 55 enters the position where the upper and lower ends of the convex platform 14 meet. Subsequently, the telescopic sleeve rod 52 drives the hook 55 to move upward under the action of its own elastic force (the force applied to the convex pin 51 is withdrawn). Finally, the hook 55 is engaged with the position where the upper and lower parts of the convex platform 14 meet. Thus, through the engagement between the hook 55 and the convex platform 14, the position of the T-shaped bracket 12 is preliminarily fixed and limited;

[0115] Finally, by manually rotating (forward) the second control valve 571, the telescopic sleeve 59 moves downward under the action of the straight rod guide seat. During this process, the spring inside the telescopic sleeve 59 and above the ring 58 presses the ring 58 (when the second control valve 571 is rotated in reverse, the telescopic sleeve 59 drives itself back to the initial position under the action of its own elastic force). When the telescopic sleeve 59 moves downward, it drives the rectangular plate 572 to move synchronously until the rectangular plate 572 contacts the convex pin 51 (and at this time, the convex pin 51 is in a just-unloaded state). Through the cooperation between the rectangular plate 572 and the convex pin 51, the engagement stability between the hook 55 and the convex platform 14 is further strengthened, and thus the firmness of the T-shaped bracket 12 is further improved.

[0116] Refer to Figure 1 and Figure 2 It can be seen that a secondary adjustment unit 7 is provided above the primary adjustment unit 2. The secondary adjustment unit 7 includes: a sliding seat 71, symmetrically and slidably installed at the upper end of the vertical section of each L-shaped seat 29; a scale line 72, etched on the side end face of each L-shaped seat 29 away from the middle position of the base plate 1; a pointer 73, fixedly installed at the middle position of the side end face of each sliding seat 71 away from the middle position of the base plate 1; a cross column 74, fixedly installed at the middle position of each sliding seat 71, and a second control valve 571 is threadedly installed on the outer wall of its upper end; a telescopic hollow rod 75, slidably installed on the outer wall above the cross column 74; an L-shaped baffle 76, fixedly installed on the outer wall of one side of the telescopic hollow rod 75; a connecting plate 77, fixedly and symmetrically distributed on the lower end face of the telescopic hollow rod 75;

[0117] Each L-shaped bracket 66 may be provided with a partial secondary limiting unit 5 composed of a straight rod 57, a circular ring 58, a telescopic sleeve 59 and a second rotary valve 571 to fix the position between the T-shaped bracket 12 and the mountain board 61 (not shown in the figure);

[0118] The water inlet layer pipe is located at the bottom and is connected to an external filtering system through an external pipe. At the same time, a plurality of small water inlet valves corresponding to the positions of the fish tanks are evenly arranged on the outer wall of the water inlet layer pipe. The water inlet layer pipe at the top is connected to an external circulation system through an external pipe.

[0119] When merchants need to replace fish tanks of different widths:

[0120] First, the sliding seat 71 is moved to the specified position. In specific implementation, the moving position of the sliding seat 71 can be determined by observing the numerical change between the calculation pointer 73 and the scale line 72. Then, the second rotating valve 571 is rotated forward for a certain number of circles. The telescopic hollow rod 75 drives the connecting plate 77 to move downward under the action of the second rotating valve 571 until the connecting plate 77 and the L-shaped seat 29 are in contact and squeezed. At this time, the positions of the L-shaped baffles on both sides of the L-shaped seat 29 are fixed (the distance between the L-shaped baffles on both sides is the width of the fish tank after the change). At the same time, the fish tank can be placed first, and then the fish tank can be fixed between the L-shaped baffles on both sides to further prevent the fish tank from shaking.

[0121] Similarly, when the aforementioned hiking board 61 rises to a specified height, the second rotary valve 571 is rotated until the telescopic sleeve 59 contacts and squeezes the hiking board 61, thereby completing the fixed limit of the position of the hiking board 61 after the height adjustment.

[0122] It is hereby explained that all the above principles are only described for a single-layer breeding rack. In specific implementation, multiple layers can be set (the mountain board 61 of each layer is mounted with the base board 1). For details, please refer to Figure 12 , and then stack and assemble a multi-layer fish farming installation frame structure to adapt to the farming of fish of different sizes or types;

[0123] During specific operation, the water in the fish tank at the corresponding position can be replaced through the laid water inlet layer pipe 81 (and the water in the fish tanks at different positions can be replaced in a targeted manner through the small water inlet valve 82), thereby ensuring that the water in the fish tank is always in a normal state suitable for the survival of zebrafish. At the same time, through the coordinated cooperation between the filtration system, the circulation system and the water inlet layer pipe 81, a closed-loop breeding system is formed, which is beneficial to the breeding of zebrafish.

[0124] The working principle of a zebrafish three-dimensional breeding system and its breeding rack installation structure provided by the present invention is as follows: First step: First, the installer presses down the convex pin 51, which drives the telescopic sleeve rod 52 to move downward until the anti-collision pad 53 contacts the upper end surface of the convex platform 14, and at this time, the pin shaft 54 is engaged with the convex platform 14, thus initially fixing the position of the T-shaped frame 12. Then, the installer manually rotates the second control valve 571 in the secondary adjustment unit 7, which drives the telescopic sleeve 59 to move downward. At the same time, the telescopic sleeve 59 drives the rectangular plate 572 to move downward until it contacts the upper and lower intersection position of the convex pin 51, that is, by limiting the position of the convex pin 51, the position of the T-shaped frame 12 is further fixed and limited.

[0125] Second step: Then, the installer rotates the first control valve 34, which drives the movable pipe 31 to move downward. During the downward movement of the convex pipe 312, the crank 317 is driven to rotate. Then, the crank 317 drives the moving plate 37 to move away from the axis of the positioning shaft 33 in the chute 36 until the contact plate 38 contacts the two side walls of the convex groove 11. Thus, the stability of the position of the C-shaped seat 21 after the adjustment rod 23 adjusts the position of the C-shaped seat 21 is completed, and further, the stability of the fish tank between the L-shaped seats 29 is ensured.

[0126] Third step: Finally, the installer rotates the second control valve 571 in the secondary adjustment unit 7, which drives the telescopic hollow rod 75 to move downward until the connecting plate 77 abuts against the L-shaped seat 29. And during this process, by observing the change of the pointer 73 with respect to the scale line 72, targeted fixing and limiting of fish tanks with different widths are carried out, thereby further improving the stability of the fish tank.

[0127] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here.

[0128] The above are only embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
