Description

Technical Field

[0001] This utility model relates to the field of ecological research box technology, and in particular to a marine biological ecological research box. Background Technology

[0002] With the deepening of research on marine ecological environment protection, marine biological ecological research boxes, as experimental closed water circulation simulation devices, are widely used in fields such as microecological simulation, biological behavior observation, and water quality parameter monitoring. These research boxes typically have multiple functions such as temperature control, filtration, and water circulation to simulate the marine environment, providing a stable and controllable living environment for experimental subjects. They are an important infrastructure for research institutions and universities to conduct marine ecological research.

[0003] Existing marine biological ecological research tanks mostly adopt a rigid structural design, with internal piping systems typically connected via threaded interfaces. Filter components are either directly placed or snap-fitted into the support frame or chamber. During operation, the entire system uses a water pump to drive water flow, which sequentially passes through the filter, aeration components, and temperature control zone before circulating back to the main chamber, thus dynamically maintaining the ecological environment. While this structural design meets basic experimental needs, its disassembly and assembly efficiency is low, and the manual operation burden is heavy during routine cleaning, filter replacement, or water system maintenance.

[0004] However, existing marine biological ecological research boxes suffer from inconvenient pipe connection and disassembly during practical use. Especially during periodic cleaning and maintenance, the commonly used threaded connections for water pipes require tools, easily causing wear or loosening of the joints. Furthermore, the cleaning process is inefficient and hinders rapid turnover. In addition, some filter structures lack effective limiting mechanisms, allowing the filters to easily shift or detach during operation, affecting filtration efficiency and water quality stability. Therefore, there is an urgent need for an ecological research box structure with rapid assembly and disassembly, and stable limiting functions, to improve the convenience of experimental operation and system stability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a marine biological ecological research box, which aims to improve the problem that the pipeline is inconvenient to disassemble and assemble during the cleaning of the ecological research box due to the threaded connection.

[0012] As a further description of the above technical solution:

[0013] A bracket is fixedly connected inside the housing, and a frame is fixedly connected to the outer wall of the filter screen.

[0014] As a further description of the above technical solution:

[0015] The frame is slidably connected inside the box, and a limiting groove is provided inside the frame.

[0016] As a further description of the above technical solution:

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a marine biological ecological research box, comprising a box body 1 for containing marine biological samples and a simulated aquatic environment. A top cover 2 is provided on the top of the box body 1 to seal the top of the box body 1 and prevent impurities from entering or water from evaporating. A filter screen 7 is provided inside the box body 1 to filter impurities in the water to maintain water quality. A water pump 3 is fixedly connected to the outer wall of the box body 1 to drive water flow for water circulation. The input end of the water pump 3 is fixedly connected to a water outlet. Pipe 4, one end of the outlet pipe 4 is fixedly connected to the inside of the tank 1. The outlet pipe 4 is used to lead water from the inside of the tank 1 to the water pump 3. The output end of the water pump 3 is fixedly connected to the connecting pipe 6. The connecting pipe 6 is used to connect to the external water circulation loop. The inlet pipe 5 is slidably connected inside the connecting pipe 6. One end of the inlet pipe 5 is fixedly connected to the inside of the tank 1. The inlet pipe 5 is used to guide the water back to the tank 1 to achieve circulation. A connecting component is provided between the inlet pipe 5 and the connecting pipe 6 to realize quick assembly and disassembly of the inlet pipe 5 and the connecting pipe 6.

[0034] The connecting assembly includes a steel ball 10, which is disposed inside the connecting pipe 6 to achieve limiting and locking functions. A disassembly sleeve 8 is slidably connected to the outer wall of the steel ball 10, which is used to push the steel ball 10 out of the limiting state for easy disassembly. A fixing groove 13 is provided inside the water inlet pipe 5, which is used to engage with the steel ball 10 to complete the locking connection. The engagement of the steel ball 10 and the fixing groove 13 ensures a stable connection and prevents the water inlet pipe 5 from falling off during operation. A sealing assembly is provided between the water inlet pipe 5 and the connecting pipe 6 to prevent water leakage at the connection point and ensure the system operates in a closed manner. A reset assembly is provided on the outer wall of the connecting pipe 6 to reset during disassembly. The automatic reset mechanism maintains the initial state of the connector after assembly. The sealing assembly includes a sealing ring 11, the outer wall of which is fixedly connected to the inside of the connecting pipe 6. The sealing ring 11 forms a sealing barrier and fits against the outer wall of the water inlet pipe 5 to seal the connection and prevent water leakage. The reset assembly includes a first spring 9, which is sleeved on the outer wall of the connecting pipe 6. The first spring 9 provides elastic support to push the disassembly sleeve 8 to reset. One end of the first spring 9 is fixedly connected to the inside of the disassembly sleeve 8, and the other end is fixedly connected to the inside of the connecting pipe 6, thereby ensuring that the steel ball 10 can automatically return to the limit position after disassembly, improving disassembly and assembly efficiency and connection reliability.

[0035] Reference Figure 4 and Figure 5Inside the housing 1, a bracket 12 is fixedly connected. The bracket 12 supports and positions the filter screen 7 and its related components, ensuring stable operation of the internal structure. A frame 14 is fixedly connected to the outer wall of the filter screen 7. The frame 14 supports the filter screen 7 and maintains its shape, facilitating installation and replacement of the filter screen inside the housing 1. The frame 14 is slidably connected inside the housing 1, allowing for guided movement within the housing 1 via a sliding structure, facilitating disassembly and maintenance of the filter screen assembly. A limiting groove 15 is provided inside the frame 14 to provide structural limiting positions, ensuring the frame 14 is fixedly positioned during installation. A limiting plate 16 is slidably connected inside the housing 1. During sliding, the limiting plate 16 can mechanically engage with the frame 14, thereby limiting the frame's range of motion. A hemispherical column 17 is fixedly connected to one side of the limiting plate 16. The hemispherical column 17 acts as a mechanical interlock, working in conjunction with the limiting groove 15 to achieve the desired fit between the filter screen and the frame. The locking and fixing of the installation position prevents the filter screen from shifting during operation; the hemispherical column 17 fits into the limiting groove 15, and the fitting structure enhances the limiting stability and improves the overall assembly accuracy; a telescopic rod 18 is provided inside the housing 1, which has the characteristic of being retractable and is used to drive the limiting plate 16 to achieve reset or clamping operation; a second spring 19 is sleeved on the outer wall of the telescopic rod 18, which provides the rebound force and works with the telescopic rod 18 to achieve the automatic reset function, enhancing the automatic limiting effect of the structure; one end of the telescopic rod 18 and the second spring 19 are both fixedly connected to the other side of the limiting plate 16. This connection method ensures that the telescopic force and the elastic force work together on the limiting plate 16, enabling it to move stably under different working conditions; the other end of the telescopic rod 18 and the second spring 19 are both fixedly connected inside the housing 1, thus forming a stable elastic limiting unit, effectively ensuring the fixation and safety of the filter screen during use.

[0036] Working principle: When using this marine life ecological research box, the filter screen 7 is first installed and supported by the frame 14. Then, the filter screen 7 is placed on the top of the support 12 for positioning by the frame 14. Then, the box body 1 and the frame 14 are locked by the hemispherical column 17 inside the box body 1 being embedded in the limiting groove 15. Then, the hemispherical column 17 is limited in the box body 1 by the limiting plate 16. At the same time, the hemispherical column 17 is supported by the tension of the second spring 19, so that the hemispherical column 17 can be stably fitted into the limiting groove 15 for locking, thus achieving the effect of limiting the filter screen 7.

[0037] When connecting the inlet pipe 5 to the water pump 3, first slide the disassembly sleeve 8 downwards, then insert the inlet pipe 5 into the connecting pipe 6. After releasing the disassembly sleeve 8, the steel ball 10 in the connecting pipe 6 is embedded in the fixing groove 13 by the tension of the first spring 9. Then, the inner wall of the disassembly sleeve 8 abuts against the outer wall of the steel ball 10 for fit. Then, the inlet pipe 5 and the connecting pipe 6 are sealed by the sealing ring 11, which achieves the effect of facilitating the disassembly and maintenance of the water pipe. Then, the water in the tank 1 is drawn into the water pump 3 through the outlet pipe 4 after being filtered by the filter screen 7. Then, the water in the tank 1 flows back to the water pump 3 through the inlet pipe 5.
