Description

Technical Field

[0001] This invention relates to the field of zooplankton culture technology, specifically to a zooplankton warming culture device suitable for outdoor environments. Background Technology

[0002] Zooplankton is a general term for heterotrophic invertebrates and chordate larvae that frequently float in water and cannot produce organic matter themselves. They are a group of animals that live a planktonic life in water. Against the backdrop of global warming, the ecological environments of some plateaus have undergone tremendous changes. Because the distribution of many zooplankton species is related to climate, they can serve as indicator animals for warm and cold currents. To better understand changes in the ecological environment, researchers need to cultivate plankton in water and explore these changes based on their growth patterns.

[0003] However, there are certain drawbacks in the current methods of culturing zooplankton. Currently, the research methods for zooplankton use indoor incubators to simulate zooplankton, but this method is divorced from the field environment, and the simulation results are not as good as those of directly culturing zooplankton in the field. No corresponding improvements have been made to address this issue. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a zooplankton warming and cultivation device suitable for the field environment. This solves the problem that current research methods for zooplankton use indoor incubators to simulate zooplankton, but this method is detached from the field environment, and the simulation results are not as good as those obtained by directly cultivating zooplankton in the field.

[0016] Beneficial effects

[0017] This invention provides a zooplankton warming and cultivation device suitable for field environments, which has the following advantages compared with the prior art:

[0018] (1) The zooplankton warming culture device suitable for the field environment has fine filter screens on the front and other surfaces of the annular PVC pipe, and an annular lamp tube is installed inside the annular PVC pipe. An annular metal heating rod is fixedly installed inside the annular PVC pipe at the outer position of the annular lamp tube. An integrated box is fitted between the annular lamp tube and the annular metal heating rod, which can make the zooplankton in the whole system only enter and not exit, forming a semi-closed system. This makes the zooplankton in the system have the same chemical composition as the zooplankton in the river, with only temperature as the single variable, which greatly increases the reliability of the experimental results.

[0019] (2) The zooplankton warming and culture device suitable for the field environment has an installation sleeve that is slidably installed on one end of a straight tube. A fixing cavity is provided on the front and rear surfaces of one end of the straight tube near the installation sleeve. A concave plate is slidably installed between the upper surfaces of the two fixing cavities. A spring is vertically and evenly connected to the upper surface of the concave plate. The lower end of the spring is fixedly connected to the upper surface of the straight tube. By using the elasticity of the spring, the concave plate can be adjusted so that the two ends of the concave plate can be inserted into or removed from the positioning groove on the insert block, thereby facilitating the installation or removal of the coarse filter and making it convenient for staff to replace the coarse filter.

[0020] (3) The zooplankton warming culture device suitable for the field environment has a motor fixedly installed inside the waterproof box. One end of the motor is rotated through and installed on one side of the coarse filter screen and fixedly connected to an L-shaped rod. A miniature time relay is fixedly installed on the upper surface of the integrated box near the rear of the battery. A brush plate is set on one side of the L-shaped rod. During the culture process, the surface of the coarse filter screen can be cleaned regularly to prevent excessive impurities on the surface of the coarse filter screen from causing blockage and thus affecting the culture effect.

[0029] Please see Figure 1-6 This invention provides a technical solution: a zooplankton warming and cultivation device suitable for outdoor environments, comprising an annular PVC pipe 1, a straight pipe 2 horizontally connected to one side of the rear of the annular PVC pipe 1, fine filters 3 provided on both the front and other surfaces of the annular PVC pipe 1, an annular lamp 4 disposed inside the annular PVC pipe 1, an annular metal heating rod 5 fixedly installed inside the annular PVC pipe 1 at the periphery of the annular lamp 4, an integrated box 6 sleeved between the annular lamp 4 and the annular metal heating rod 5, and a mounting sleeve 11 slidably mounted on one end of the straight pipe 2, with the front and rear surfaces of one end of the straight pipe 2 close to the mounting sleeve 11. A fixed cavity 12 is provided on one side. A concave plate 13 is slidably installed between the upper surfaces of the two fixed cavities 12. A spring 14 is vertically and evenly connected to the upper surface of the inner concave plate 13. The lower end of the spring 14 is fixedly connected to the upper surface of the straight tube 2. Two inserts 15 corresponding to the fixed cavities 12 are symmetrically arranged on one side of the mounting sleeve 11. A coarse filter screen 16 is provided inside the other side of the mounting sleeve 11. A waterproof box 17 is provided in the middle of one side surface of the coarse filter screen 16. A motor 18 is fixedly installed inside the waterproof box 17. One end of the motor 18 is rotatably installed through one side of the coarse filter screen 16 and fixedly connected to an L-shaped rod 19.

[0030] A microcontroller 7 is horizontally mounted inside the integrated box 6. A sensor 8 is mounted on the upper surface of the microcontroller 7. A battery 9 is fixedly mounted on the upper surface of the integrated box 6, and a miniature time relay 10 is fixedly mounted on the upper surface of the integrated box 6 near the rear of the battery 9. The motor 18 is electrically connected to the miniature time relay 10 via a wire. The annular metal heating rod 5 is electrically connected to the microcontroller 7 via a wire. The microcontroller 7 is electrically connected to the sensor 8 via a wire. The annular lamp 4, the sensor 8, and the miniature time relay 10 are all electrically connected to the battery 9 via wires. The miniature time relay 10 causes the motor 18 to work once every 2 hours to ensure that all components are powered and can work normally.

[0031] Please see Figure 1 Both the annular PVC pipe 1 and the straight pipe 2 are transparent. During the day, in order for the zooplankton to be exposed to light, the front surface of the annular PVC pipe 1 is horizontally connected to the two sides of the fine filter screen 3, and the lower surface of the annular PVC pipe 1 is vertically connected to the second positioning rod 102. One end of the first positioning rod 101 and the second positioning rod 102 is provided with a tip 103. In order to fix the device in the water, the fine filter screen 3 is a No. 25 filter screen to prevent the zooplankton from swimming out.

[0032] Please see Figure 2 A waterproof packaging film 61 is wrapped between the outer surface of the ring lamp tube 4, the ring metal heating rod 5, and the integrated box 6 to serve as a waterproof layer.

[0033] Please see Figure 3 The microcontroller 7 presets a temperature increase value of 2℃ for the annular metal heating rod 5. Both sides of the sensor 8 are equipped with sensing probes 81. The two sensing probes 81 detect the water temperature inside and outside the annular PVC pipe 1 respectively, in order to ensure that the temperature difference between the inside and outside of the annular PVC pipe 1 is within 2℃.

[0034] Please see Figure 4-5 A handle 131 is provided at the middle position of the upper surface of the concave plate 13. The spring 14 is a stainless steel component. In order to facilitate pulling the handle 131, stainless steel can play a rust-proof role. The upper surface of the insert block 15 is provided with a positioning groove 151 that matches one end of the concave plate 13. One end of the concave plate 13 is slidably snapped into the inside of the positioning groove 151. When both ends of the concave plate 13 are snapped into the positioning groove 151, it can fix the mounting sleeve 11.

[0035] Please see Figure 6A brush plate 191 is provided on one side of the L-shaped rod 19. One side of the brush plate 191 contacts the other side of the coarse filter screen 16. One end of the L-shaped rod 19 is slidably mounted on the outer surface of the mounting sleeve 11. When the motor 18 rotates, it can drive the brush plate 191 on the L-shaped rod 19 to rotate, which can clean the impurities on the coarse filter screen 16. When the L-shaped rod 19 rotates, it will slide on the mounting sleeve 11 to improve its stability.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] In use, first, place the annular PVC pipe 1 into the water, ensuring the straight pipe 2 is parallel to the water flow direction. Then, insert the tip 103 of the first positioning rod 101 into the side wall of the bottom, and insert the second positioning rod 102 into the bottom to fix the annular PVC pipe 1. When water passes through the straight pipe 2, the coarse filter 16 filters out impurities, allowing zooplankton to enter. The water that enters can flow out through the fine filter 3. Since the fine filter 3 uses a No. 25 filter, it prevents zooplankton from swimming away. During the day, because both the annular PVC pipe 1 and the straight pipe 2 are transparent, zooplankton can... To ensure the water receives the same light as zooplankton in the wild, the ring lamp 4 is powered on at night. The ring lamp 4 increases chlorophyll in the river, accelerating the experiment. Two sensor probes 81 on the sensor 8 detect the temperature of the water inside and outside the ring PVC pipe 1. If the temperature difference is too large, the microcontroller 7, pre-set to increase the temperature of the ring metal heating rod 5 by 2°C, will heat the ring metal heating rod 5. When the two sensor probes 81 detect a temperature difference of 2°C, the heating of the ring metal heating rod 5 will stop. To maintain a temperature difference within 2°C, the coarse filter 16 is installed by placing the mounting sleeve 11 over one end of the straight pipe 2 and inserting the two inserts 15 on the mounting sleeve 11 into the two fixed cavities 12. Before insertion, the handle 131 on the concave plate 13 is pulled, and the spring 14 causes the two ends of the concave plate 13 to move away from the fixed cavity 12. When the inserts 15 are inserted into the fixed cavity 12, the handle 131 is released, allowing the two ends of the concave plate 13 to engage with the positioning grooves 151 on the two inserts 15. This completes the installation of the coarse filter 16. When disassembling, pull the handle 131 again to make the two ends of the concave plate 13 leave the positioning groove 151 on the insert block 15, and then slide the mounting sleeve 11 out of the straight tube 2. Next, the motor 18 inside the waterproof box 17 is made to work once every 2 hours by using the miniature time relay 10 of model DH48S-S. When the motor 18 works, it will drive the L-shaped rod 19 to rotate. When the L-shaped rod 19 rotates, the brush plate 191 on the L-shaped rod 19 will wipe the surface of the coarse filter screen 16 to remove the impurities adhering to the surface of the coarse filter screen 16 and prevent the coarse filter screen 16 from becoming clogged.
