Description

Technical Field

[0001] This utility model relates to the field of negative pressure aquarium technology, and in particular to a dual-liquid-level negative pressure aquarium. Background Technology

[0002] Currently, most of the interactive negative pressure aquariums installed in marine parks are made of acrylic, constructed from acrylic sheets of varying thicknesses from 30 to 80 mm. The negative pressure height is only a few tens of centimeters, with a maximum of no more than 1 meter. For safety reasons, the acrylic thickness is excessive, resulting in a high cost.

[0003] Currently, in the case of a dual-level negative pressure aquarium, a large amount of fish excrement accumulates at the bottom of the aquarium after prolonged use, making cleaning very troublesome and impractical. In addition, the internal components of the current dual-level negative pressure aquarium are all integrated, making it inconvenient to disassemble for cleaning or replacement, further reducing its practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where a lot of fish excrement accumulates at the bottom of the aquarium after long-term use, making cleaning very troublesome, and the internal components are all integrated, making it inconvenient to disassemble for cleaning or replacement, resulting in poor practicality. Therefore, a dual-liquid-level negative pressure aquarium is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-level negative pressure fish tank, comprising a first fish tank body, a second fish tank body disposed within the first fish tank body, an air absorber disposed within the second fish tank body, a low-level detector installed on the inner wall of the first fish tank body, a high-level detector installed above the low-level detector on the inner wall of the first fish tank body, a baffle plate disposed below the second fish tank body within the first fish tank body, a collection box placed against the bottom end of the baffle plate within the first fish tank body, a water outlet pipe fixed to one end of the collection box, and the end of the water outlet pipe away from the collection box penetrating the first fish tank body and disposed outside the first fish tank body.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a dual-level negative pressure aquarium, including a first aquarium body 1, a second aquarium body 2 inside the first aquarium body 1, an air extractor 4 inside the second aquarium body 2, a low-level detector 6 installed on the inner wall of the first aquarium body 1, a high-level detector 5 installed above the low-level detector 6 on the inner wall of the first aquarium body 1, a baffle plate 7 located below the second aquarium body 2 inside the first aquarium body 1, a collection box 16 placed against the bottom of the baffle plate 7 inside the first aquarium body 1, a water outlet pipe 18 fixed to one end of the collection box 16, and the end of the water outlet pipe 18 away from the collection box 16 passing through the first aquarium body 1 and located outside the first aquarium body 1.

[0021] The overall effect of Embodiment 1 is as follows: by operating the air extractor 4, air is drawn from the second aquarium body 2, creating a negative pressure inside the second aquarium body 2, which draws water from the first aquarium body 1. Through the high-level detector 5 and the low-level detector 6, when the water level in the first aquarium body 1 is lower than the low-level detector 6, the low-level detector 6 controls the externally connected water outlet device to replenish water to the first aquarium body 1. Conversely, when the water level in the first aquarium body 1 is higher than the high-level detector 5, the high-level detector 5 controls the externally connected water outlet device to stop adding water. The barrier plate 7 allows fish excrement to fall through the gaps in the barrier plate 7 while preventing fish from entering the subsequent collection box 16. The collection box 16 allows for centralized collection of fish excrement for easy cleaning. The water outlet pipe 18 allows for drainage.

[0022] Example 2, as Figure 1-4 As shown, both ends of the baffle plate 7 are fixed with first sliders 9, and the tops of the two first sliders 9 are fixed with handles 10. The inner walls of the first fish tank body 1 have first openings 11 at both ends that match the first sliders 9. The inner walls of the first fish tank body 1 have second openings 13 at the tops of the first openings 11 at both ends. Second sliders 12 are slidably connected within the second openings 13. The second sliders 12 are fixed to the first fish tank body 1 by first bolts 14. Connecting plates 15 are fixed to the opposite ends of the two second sliders 12. The opposite ends of the two connecting plates 15 are connected to the second fish tank body 1. The two second sliders 12 are fixed together, and the bottom ends of the two second sliders 12 abut against the top end of the handle 10. The bottom end of the collection box 16 is fixed with a base plate 17. The base plate 17 is fixed to the first fish tank body 1 by the second bolt 22. Multiple planting boxes 8 are fixed to the top end of the barrier plate 7. A bracket 21 is fixed to the outer wall of the first fish tank body 1. A support plate 3 is fixed to the inner wall of the second fish tank body 2. An air absorber 4 is installed on the top end of the support plate 3. A slot 20 matching the water outlet pipe 18 is opened at one end of the first fish tank body 1. A flange 19 is fixed to the outer wall of the end of the water outlet pipe 18 away from the collection box 16.

[0023] The overall effect of Embodiment 2 is that, through the setting of the baffle plate 7, the fish excrement is concentrated and falls into the collection box 16 through the gaps between the baffle plates 7. When the first fish tank body 1 discharges water through the outlet pipe 18, the user can directly remove the second bolt 22 to directly remove the bottom plate 17 and the collection box 16, and can directly rinse the excrement in the collection box 16 without the user having to reach into the fish tank to scoop it out, which is more practical. In addition, by unscrewing the first bolt 14, the second slider 12 is no longer fixed to the first fish tank body 1, and the user can directly remove the first fish tank body 1 for replacement or cleaning. When the first fish tank body 1 is removed, the second slider 12 no longer limits the handle 10, and the user can directly remove the baffle plate 7 through the handle 10 to plant or clean the planting box 8 fixed at the top, which is more practical. The flange 19 facilitates connection to an external sewage treatment facility.

[0024] Working principle: When this device is in use, the air extractor 4 evacuates air from the second aquarium body 2, creating a negative pressure inside. This causes water to be drawn from the first aquarium body 1. Through the high-level detector 5 and low-level detector 6, when the water level in the first aquarium body 1 is lower than the low-level detector 6, the low-level detector 6 controls the external water outlet device to replenish water to the first aquarium body 1. Conversely, when the water level in the first aquarium body 1 is higher than the high-level detector 5, the high-level detector 5 controls the external water outlet device to stop adding water. The baffle plates 7 allow fish excrement to fall through the gaps and into the collection box 16. When the first aquarium body 1 is filled with water through the outlet pipe 18... When draining water, the user can directly remove the second bolt 22 to remove the base plate 17 and collection box 16, allowing for direct flushing of the excrement in the collection box 16 without the user needing to reach into the aquarium to retrieve it, thus enhancing practicality. Additionally, by unscrewing the first bolt 14, the second slider 12 is no longer fixed to the first aquarium body 1, allowing the user to directly remove the first aquarium body 1 for replacement or cleaning. Furthermore, when the first aquarium body 1 is removed, the second slider 12 no longer limits the handle 10, allowing the user to directly remove the barrier plate 7 through the handle 10 to plant or clean the planting box 8 fixed at its top, further enhancing practicality. The flange 19 facilitates connection to external wastewater treatment systems.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
