Description

Technical Field

[0001] This invention relates to the field of algae cultivation technology, specifically to an intelligent, fully enclosed, built-in luminescent microalgae cultivation device. Background Technology

[0002] Microalgae refer to tiny algal communities whose morphology can only be discerned under a microscope. Microalgae generally refer to a collective term for microorganisms containing chlorophyll a and capable of photosynthesis, belonging to a type of protist organism. Microalgae cultivation typically involves adding a certain amount of inorganic or organic nutrients to a transparent container to prepare a nutrient solution. Algal inoculum is then inoculated into the container. Finally, the temperature and light are adjusted according to the algal growth requirements. Once the algal solution reaches a certain density, it can be harvested once and then used for large-scale cultivation. Light is one of the most important factors affecting microalgae growth.

[0003] When irradiating microalgae with light sources, natural light or artificial light sources are generally used. However, due to the instability of natural light sources and the fact that indoor cultivation also affects the penetration of natural light, artificial light sources are often used for cultivation. However, when irradiating with artificial light sources (lamp tubes), the light source can only illuminate one side of the cultivation container, which can easily cause uneven irradiation of microalgae and affect algae growth. In addition, most cultivation tanks have complex structures, which can easily reduce the efficiency of microalgae harvesting. Summary of the Invention

[0004] The purpose of this invention is to position the culture tube diagonally opposite the supplemental light using a limiting mechanism. By continuously adjusting the corresponding surfaces of the culture tube and the supplemental light, uniform and all-round irradiation of the outer surface of the culture tube can be achieved, further improving the light effect on the microalgae inside the culture tube and promoting their growth. Furthermore, the use of a reset mechanism in conjunction with the limiting mechanism not only further assists the operation of the limiting mechanism but also facilitates the removal of the culture tube, effectively improving harvesting efficiency.

[0005] The objective of this invention can be achieved through the following technical solution: an intelligent, fully enclosed, built-in luminescent microalgae cultivation device, comprising a fixed box, cultivation tubes, and supplemental lighting. The top of the fixed box is open. Cultivation tubes are installed at one corner of the front end and another corner of the rear end inside the fixed box, with the two sets of cultivation tubes arranged diagonally. The supplemental lighting is located at the center inside the fixed box, and a drive motor is fixedly connected to the lamp holder at the bottom of the supplemental lighting. The top of the supplemental lighting extends to the upper opening of the fixed box and is fixedly installed with a limiting plate. Conical blades are fixedly installed at equal intervals on the outside of the limiting plate, and the end of the conical blades away from the limiting plate is rounded. Several sets of toothed blocks are fixedly installed at equal intervals on the rounded corner surface. A limiting mechanism is provided at the top of each of the two sets of cultivation tubes inside the fixed box. A reset mechanism is provided at the bottom of the fixed box corresponding to the limiting mechanism.

[0006] Furthermore, a temperature sensor is installed at the top opening of each of the aquaculture pipes, and the temperature sensor is connected to the controller.

[0007] Furthermore, supplementary lighting plates are installed at the other two corners inside the fixed box and at the corresponding positions of the two sets of breeding pipes. The two sets of supplementary lighting plates are diagonally symmetrical and folded. Reflective lenses are embedded in the opposite sides of the two sets of supplementary lighting plates.

[0008] Furthermore, the two sets of limiting mechanisms are arranged diagonally symmetrically. Each limiting mechanism includes a fixed plate and a movable plate. The fixed plate is inclinedly and fixedly inserted into the upper corner of the fixed box. The movable plate is movable and inserted into the upper corner of the fixed box, and the movable plate is parallel to and corresponds to the fixed plate. A hinge rod is hinged between the movable plate and the fixed plate at their front and rear centers. A toothed groove is provided on both outer surfaces of the movable plate. A limiting inner cylinder is engaged at the center between the fixed plate and the movable plate. A toothed groove matching the toothed groove is provided on the outer surface of the limiting inner cylinder near its lower end, and the toothed grooves mesh with each other. The top of the limiting inner cylinder extends to the upper end of the fixed plate and the movable plate and is fitted with a limiting outer cylinder.

[0009] Furthermore, the limiting inner cylinder is sleeved with a limiting outer cylinder near its upper end, and several sets of toothed blocks are fixedly installed in the middle section of the inner surface of the limiting outer cylinder. Several sets of arc-shaped grooves are evenly arranged on the outer wall of the limiting inner cylinder. Each set of arc-shaped grooves is rotatably connected to a leaf-shaped abutment. Several sets of toothed grooves are evenly opened on the curved surface of the leaf-shaped abutment. The toothed grooves mesh with the toothed blocks.

[0010] Furthermore, the reset mechanism includes a stop cylinder, which is fixedly installed on the inner wall of the bottom of the fixed box. The stop cylinder has a tapered structure that is wider at the top and narrower at the bottom. A long cylinder is rotatably connected to the center of the stop cylinder, and a spring damper is fixedly installed inside the long cylinder. A T-shaped push rod is inserted into the long cylinder at the upper end of the spring damper, and the top of the push rod passes through the long cylinder and is fixedly connected to a storage cylinder.

[0011] Furthermore, insert frames are inserted into both sides of the storage tube, and both ends of the insert frames are curved. One end of the insert frame extends into the interior of the storage tube, and a concave tube and an insert rod are respectively provided on the inner wall of the other side of the insert frame and the outer surface of one side of the storage tube. The insert rod is inserted into the interior of the concave tube, and a spring assembly is fixedly connected between the insert rod and the interior of the concave tube.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This invention sets two limiting mechanisms at the supplemental lighting location, and inserts the cultivation tubes into the limiting mechanisms respectively. The cultivation tubes pass through the limiting inner cylinder, and their tops near the tube opening are limited inside the limiting inner cylinder. Then, the limiting outer cylinder is turned clockwise, and the limiting inner cylinder remains stationary. The toothed blocks on the inner wall of the limiting outer cylinder respectively engage with the toothed grooves on the outer periphery of the leaf-shaped abutments, forcing four sets of leaf-shaped abutments to rotate simultaneously until the pointed tips of the four sets of leaf-shaped abutments press against the edge of the cultivation tube, thus limiting the cultivation tube. The supplemental lighting is then used to illuminate the microalgae. During the illumination process, the light shines on the supplemental lighting plate and is refracted to the outside of the cultivation tube, thereby increasing the illumination area of ​​the cultivation tube and improving the cultivation effect. Furthermore, a temperature sensor is set up to transmit the water temperature information of the cultivation tube to the controller. The controller judges and prompts, facilitating timely adjustment of the water temperature to improve the state of microalgae cultivation.

[0014] 2. When the present invention utilizes the clamping mechanism, the drive motor is activated, which drives the supplementary light and the limiting plate to rotate clockwise. The conical blades at the edge of the limiting plate rotate accordingly. When one set of conical blades approaches the movable plate, the tooth block one on the outside of the conical blades engages with the tooth groove one on the outer surface of the movable plate. The movable plate first tilts backward. During this process, the tooth groove one on the inner side of the movable plate engages with the tooth groove two on the outer surface of the limiting inner cylinder, thereby driving the limiting inner cylinder and the aquaculture tube to rotate circumferentially, adjusting the opposing surfaces of the aquaculture tube and the supplementary light. Then, the drive motor drives the conical blades to rotate in the opposite direction, and the conical blades engage with the movable plate again, forcing the movable plate to tilt forward and driving the aquaculture tube to rotate back to its position. This process is repeated, and by continuously adjusting the corresponding surfaces of the aquaculture tube and the supplementary light, uniform and all-round irradiation of the outer surface of the aquaculture tube is achieved, further improving the light effect on the microalgae inside the aquaculture tube, which is beneficial to the growth of microalgae.

[0015] 3. This invention includes a reset mechanism that works in conjunction with a limiting mechanism. The bottom of the culture tube is inserted into the storage tube and pressed downwards until the push rod presses against the spring damper to a compressed state. The storage tube is then inserted into the support tube. Because the support tube has a tapered structure that is wider at the top and narrower at the bottom, when the storage tube descends to a certain height, the protruding insert frames on both sides are pressed against the inclined inner wall of the support tube and inserted parallel to the inside of the storage tube, while the insert rod is inserted into the concave tube. The spring assembly is compressed until the two sets of insert frames press against the outer wall of the bottom of the culture tube, further limiting the culture tube and keeping it at the same horizontal level as the supplemental light. During harvesting after inoculation, the limiting mechanism at the top of the culture tube is first released, and the bottom of the culture tube resets under the restoring force of the spring damper, assisting the culture tube and the storage tube to spring upwards, forcing the top of the culture tube to exceed the top of the fixed box, thereby facilitating the removal of the culture tube and effectively improving harvesting efficiency.

[0026] Example 1:

[0027] Please see Figure 1 - Figure 7As shown, the intelligent, fully enclosed, built-in luminescent microalgae cultivation device includes a fixed box 1, cultivation tubes 2, and supplemental lighting 3. The top of the fixed box 1 is open. Cultivation tubes 2 are installed at one corner of the front end and another corner of the rear end inside the fixed box 1. The two sets of cultivation tubes 2 are diagonally distributed. The supplemental lighting 3 is located at the center inside the fixed box 1, and a drive motor 4 is fixedly connected to the lamp holder at the bottom of the supplemental lighting 3. The top of the supplemental lighting 3 extends to the upper opening of the fixed box 1 and is fixedly installed with a limiting plate 5. Conical blades 6 are fixedly installed at equal intervals on the outside of the limiting plate 5, and the end of the conical blades 6 away from the limiting plate 5 is rounded. Several sets of toothed blocks 61 are fixedly installed at equal intervals on the rounded surface. A limiting mechanism 7 is provided at the top of each of the two sets of cultivation tubes 2 inside the fixed box 1. A reset mechanism 8 is provided at the bottom of the fixed box 1 corresponding to the limiting mechanism 7. Supplementary lighting plates 9 are installed at the other two corners inside the fixed box 1 and at the corresponding positions of the two sets of breeding pipes 2. The two sets of supplementary lighting plates 9 are diagonally symmetrical and folded. Reflective lenses 91 are embedded in the opposite sides of the two sets of supplementary lighting plates 9.

[0028] During operation, microalgae seedlings are divided into two sets of culture tubes 2, which are then inserted into the fixed box 1 and constrained by the limiting mechanism 7. The two sets are placed diagonally. Supplemental lighting 3 is located between the two sets of culture tubes 2 to provide supplemental lighting for the microalgae. During the illumination process, the light from the supplemental lighting 3 shines on the supplemental lighting plate 9 and is refracted to the outside of the culture tubes 2, thereby increasing the illumination area of ​​the culture tubes 2 and improving the planting effect. A temperature sensor is installed at the top of each set of culture tubes 2. The temperature sensor is connected to the controller and transmits the water temperature information of the culture tube to the controller. The controller makes a judgment and provides a prompt, which facilitates timely adjustment of the water temperature to improve the microalgae cultivation status.

[0029] Example 2:

[0030] Please see Figure 2 - Figure 5As shown, the two sets of limiting mechanisms 7 are arranged diagonally symmetrically. The limiting mechanism 7 includes a fixed plate 71 and a movable plate 72. The fixed plate 71 is inclined and fixedly inserted into the upper corner of the inside of the fixed box 1. The movable plate 72 is movable and inserted into the upper corner of the inside of the fixed box 1. The movable plate 72 is parallel and corresponding to the fixed plate 71. The movable plate 72 and the fixed plate 71 are hinged at the front and rear center of the front and rear, respectively. The outer surfaces of both sides of the movable plate 72 are provided with a toothed groove 74. The center of the fixed plate 71 and the movable plate 72 is engaged with a limiting inner cylinder 75. The outer surface of the limiting inner cylinder 75 is provided with a toothed groove 76 that matches the toothed groove 74 near the lower end. The toothed groove 74 and the toothed groove 76 mesh with each other. The top of the limiting inner cylinder 75 extends to the upper end of the fixed plate 71 and the movable plate 72 and is fitted with a limiting outer cylinder 77. The inner limiting cylinder 75 is sleeved with the outer limiting cylinder 77 near the upper end, and several sets of toothed blocks 78 are fixedly installed in the middle section of the inner surface of the outer limiting cylinder 77. Several sets of arc-shaped grooves 79 are evenly arranged on the outer wall of the inner limiting cylinder 75. Each set of arc-shaped grooves 79 is rotatably connected to a leaf-shaped abutment 710, and several sets of toothed grooves 711 are evenly opened on the curved surface of the leaf-shaped abutment 710. The toothed grooves 711 mesh with the toothed blocks 78.

[0031] Two sets of breeding tubes 2 are respectively inserted into two corners of the fixed box 1 and limited by the limiting mechanism 7. The breeding tube 2 passes through the limiting inner cylinder 75, and its top near the tube opening is limited inside the limiting inner cylinder 75. Then, the limiting outer cylinder 77 is turned clockwise, and the limiting inner cylinder 75 remains stationary. The toothed blocks 78 on the inner wall of the limiting outer cylinder 77 respectively engage with the toothed grooves 711 on the outer periphery of the leaf-shaped abutments 710, forcing all four sets of leaf-shaped abutments 710 to rotate until the pointed ends of the four sets of leaf-shaped abutments 710 press against the edge of the breeding tube 2, thus limiting the breeding tube 2. Then, the drive motor 4 is started, which drives the supplementary light 3 and the limiting plate 5 to rotate clockwise. The conical blades 6 at the edge of the limiting plate 5 rotate accordingly. When one set of conical blades 6 approaches the movable plate 72, the toothed blocks 61 on the outer surface of the conical blades 6 engage with the toothed grooves 74 on the outer surface of the movable plate 72. First, it tilts backward. During this process, the toothed groove 74 on the inner side of the movable plate 72 engages with the toothed groove 76 on the outer surface of the limiting inner cylinder 75, thereby driving the limiting inner cylinder 75 and the aquaculture tube 2 to rotate in a circular motion. This adjusts the opposing surfaces of the aquaculture tube 2 and the supplemental light 3. Then, the drive motor 4 drives the conical blade 6 to rotate in the opposite direction. The conical blade 6 engages with the movable plate 72 again, forcing the movable plate 72 to tilt forward and drive the aquaculture tube 2 to rotate back to its original position. This process is repeated, and by continuously adjusting the corresponding surfaces of the aquaculture tube 2 and the supplemental light 3, uniform and all-round irradiation of the outer surface of the aquaculture tube 2 is achieved, further improving the light effect on the microalgae inside the aquaculture tube 2, which is beneficial to the growth of microalgae.

[0032] Example 3:

[0033] Please see Figure 3 - Figure 6 and Figure 7 As shown, the reset mechanism 8 includes a stop cylinder 81, which is fixedly installed on the inner wall of the bottom of the fixed box 1. The stop cylinder 81 has a tapered structure that is wider at the top and narrower at the bottom. A long cylinder 82 is rotatably connected to the center of the inside of the stop cylinder 81. A spring damper 83 is fixedly installed inside the long cylinder 82. A T-shaped push rod 84 is inserted into the upper end of the spring damper 83 inside the long cylinder 82. The top of the push rod 84 passes through the long cylinder 82 and is fixedly connected to a storage cylinder 85.

[0034] Insert frames 86 are inserted into both sides of the storage tube 85, and both ends of the insert frames 86 are curved. One end of the insert frame 86 extends into the interior of the storage tube 85, and a concave tube 87 and an insert rod 88 are respectively provided on the inner wall of the other side of the insert frame 86 and the outer surface of one side of the storage tube 85. The insert rod 88 is inserted into the interior of the concave tube 87, and a spring assembly 89 is fixedly connected between the insert rod 88 and the interior of the concave tube 87.

[0035] During operation, the two sets of breeding tubes 2 are respectively inserted into the two corners of the fixed box 1. The bottom of the breeding tube 2 is inserted into the inside of the storage tube 85 and pressed downwards until the push rod 84 presses against the spring damper 83 to a compressed state. The storage tube 85 is inserted into the backing tube 81. Since the backing tube 81 has a conical structure that is wider at the top and narrower at the bottom, when the storage tube 85 descends to a certain height, the protruding insertion frames 86 on both sides are pressed against the inclined inner wall of the backing tube 81 and inserted parallel to the inside of the storage tube 85. Meanwhile, the insertion rod 88 is inserted into the concave tube 87. The spring assembly 8... 9. Compress until the two sets of insert frames 86 press against the bottom outer wall of the culture tube 2 to further restrict the culture tube 2, keep the culture tube 2 and the supplemental light 3 at the same level, and during the harvest after inoculation, first release the restriction mechanism 7 at the top of the culture tube 2. The bottom of the culture tube 2 is reset under the restoring force of the spring damper 83, which helps the culture tube 2 and the storage tube 85 to spring upward, forcing the top of the culture tube 2 to exceed the top of the fixed box 1, thereby facilitating the removal of the culture tube 2 and effectively improving the harvesting efficiency.

[0036] Working principle:

[0037] In use, the microalgae seedlings are divided into two sets of cultivation tubes 2, which are then inserted into a fixed box 1 and secured by a limiting mechanism 7. The two sets are placed diagonally. A supplemental light 3 is positioned between the two sets of cultivation tubes 2 to provide supplemental lighting for the microalgae. During illumination, the light from the supplemental light 3 illuminates the supplemental light plate 9 and is refracted to the outside of the cultivation tubes 2, thereby increasing the irradiation area and improving the cultivation effect. The cultivation tubes 2 pass through the inner limiting cylinder 75, and their tops are confined within the inner limiting cylinder 75 near the tube opening. Then, the outer limiting cylinder 77 is rotated clockwise, keeping the inner limiting cylinder 75 stationary and the outer limiting cylinder 77... The inner wall toothed blocks 78 engage with the toothed grooves 711 on the outer periphery of the leaf-shaped abutments 710, forcing all four sets of leaf-shaped abutments 710 to rotate simultaneously until the pointed tips of the four sets of leaf-shaped abutments 710 press against the edge of the aquaculture tube 2, thus limiting the aquaculture tube 2. Then, the drive motor 4 is started, which drives the supplementary light 3 and the limiting plate 5 to rotate clockwise. The conical blades 6 at the edge of the limiting plate 5 rotate accordingly. When one set of conical blades 6 approaches the movable plate 72, the toothed blocks 61 on the outer side of the conical blades 6 engage with the toothed grooves 74 on the outer surface of the movable plate 72. The movable plate 72 first tilts backward. During this process, the toothed grooves 74 on the inner side of the movable plate 72 engage with the toothed grooves 76 on the outer surface of the limiting inner cylinder 75, thereby driving the limiting inner cylinder 75 and the aquaculture tube 2 to rotate circumferentially, adjusting the opposing surfaces of the aquaculture tube 2 and the supplementary light 3. Then, the drive motor 4 drives the conical blades 6... Reverse rotation causes the conical blade 6 to engage with the movable plate 72 again, forcing the movable plate 72 to tilt forward and move, and causing the culture tube 2 to rotate back to its original position. This process is repeated, and by continuously adjusting the corresponding surfaces of the culture tube 2 and the supplemental light 3, uniform and all-round irradiation of the outer surface of the culture tube 2 is achieved, further improving the light effect on the microalgae inside the culture tube 2, which is beneficial to the growth of microalgae.

[0038] Two sets of breeding tubes 2 are respectively inserted into two corners of the fixed box 1. The bottom of the breeding tube 2 is inserted into the inside of the storage tube 85 and pressed downward until the push rod 84 presses against the spring damper 83 to a compressed state. The storage tube 85 is inserted into the inside of the support tube 81. Since the support tube 81 has a conical structure that is wider at the top and narrower at the bottom, when the storage tube 85 descends to a certain height, the protruding insertion frames 86 on both sides are pressed against the inclined inner wall of the support tube 81 and inserted into the storage tube 85 in parallel. The insertion rod 88 is inserted into the concave tube 87. The spring group 89 is compressed until the two sets of insertion frames 86 press against the bottom outer wall of the breeding tube 2 to further limit the breeding tube 2 and keep the breeding tube 2 and the supplementary light 3 at the same horizontal plane.

[0039] During the cultivation process, a temperature sensor is installed at the top of each cultivation tube 2. The temperature sensor is connected to the controller and transmits the water temperature information of the cultivation tube to the controller. The controller makes a judgment and provides a prompt, so as to adjust the water temperature in time to improve the state of microalgae cultivation. After inoculation, during harvesting, the limiting mechanism 7 at the top of the cultivation tube 2 is first released. The bottom of the cultivation tube 2 is reset under the restoring force of the spring damper 83, which helps the cultivation tube 2 and the storage tube 85 to spring upward, forcing the top of the cultivation tube 2 to exceed the top of the fixed box 1, thereby facilitating the removal of the cultivation tube 2 and effectively improving the harvesting efficiency.
