Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and more specifically, to a fish tank device. Background Technology

[0002] Currently, in the field of aquaculture equipment, especially in household or commercial fish tank systems, water pumps are widely used as the core component for maintaining water circulation and filtration. Through continuous operation, the water pump draws water from the fish tank and delivers it to the filter, where it is purified before flowing back into the tank, ensuring water cleanliness and oxygen levels, and providing a suitable living environment for the fish.

[0003] However, to maintain the cleanliness of the aquarium, the water pump usually needs to run for extended periods, and the accumulated electricity consumption over time leads to high costs for fishkeeping. This is especially true for large aquariums or multi-tank aquariums, where the continuous high-load operation of the water pump significantly increases electricity expenses. Utility Model Content

[0004] The problem this invention addresses is how to reduce the electricity cost of aquarium devices.

[0005] To solve the above problems, this utility model provides a fish tank device, including a fish tank body, a water pump, a power conversion device, pipes, a filter, a hydroelectric power generation device, an energy storage device, and a first switch; the hydroelectric power generation device includes turbine blades and a generator connected by a rotating shaft, the generator is electrically connected to the energy storage device, and the energy storage device is electrically connected to the power conversion device through the first switch; The water pump is located in the aquarium body and is electrically connected to the power adapter. The water pump is provided with a first outlet for exporting the water to be filtered from the aquarium body. The pipe is provided with a first port connected to the first outlet and a second port for importing the water to be filtered into the filter. The filter is used to convert the water to be filtered into filtered water. The filter is provided with a second outlet for discharging the filtered water. The turbine blades are located below the second outlet and above the aquarium body.

[0006] Optionally, the hydroelectric power generation device further includes a housing for accommodating the turbine blades; one end of the housing is provided with a first inlet connected to the second outlet, and the other end is provided with a third outlet; the turbine blades are located between the first inlet and the third outlet.

[0007] Optionally, the aquarium body is a shell structure with a first opening on the top surface, and the bottom end of the third water outlet is located above the first opening.

[0008] Optionally, the filter is a housing structure with a second opening end on the top surface, the second opening end being located below the second port and above the second outlet.

[0009] Optionally, the aquarium device further includes a second switch; the generator is electrically connected to the energy storage device via the second switch.

[0010] Optionally, the aquarium device also includes a solar power generation device and a third switch; the solar power generation device is electrically connected to the power conversion device via the third switch.

[0011] Optionally, the aquarium device further includes a fourth switch; the water pump is electrically connected to the power adapter via the fourth switch.

[0012] Optionally, the aquarium device further includes a heating device and a fifth switch; the heating device is electrically connected to the power conversion device via the fifth switch.

[0013] Optionally, the aquarium device further includes an oxygenation device and a sixth switch; the oxygenation device is electrically connected to the power conversion device via the sixth switch.

[0014] Optionally, the power adapter is provided with at least one extended output port.

[0015] In this invention, a water pump is located inside the aquarium and electrically connected to a power adapter. The water pump has a first outlet for draining the water to be filtered from the aquarium, a first port on the pipe connected to the first outlet, and a second port for introducing the water to be filtered into a filter. Thus, when the power adapter is connected to, for example, mains power, it drives the water pump to introduce the water to be filtered from the aquarium through the pipe into the filter for filtration, thereby converting the water to be filtered into filtered water. The filter has a second outlet for draining the filtered water, with turbine blades located below the second outlet and above the aquarium. Therefore, the filtered water drained from the second outlet flows back into the aquarium after passing through the turbine blades, and at this time, the filtered water enters the aquarium from above, providing a certain degree of oxygenation. During this process, the filtered water, under the influence of gravity, drives the turbine blades to rotate, thereby converting the kinetic energy of the water flow into electrical energy through a generator connected to the rotating shaft. In this invention, the generator and energy storage device, such as a battery, are electrically connected. After the hydroelectric power generation device converts kinetic energy into electrical energy, the electrical energy can be stored in the energy storage device, thus realizing energy recovery and improving the overall energy utilization efficiency of the aquarium device. Simultaneously, the energy storage device is electrically connected to a power conversion device via a first switch. In scenarios such as power outages or when the stored energy is sufficient to power the aquarium device for a period of time, the operator can close the first switch to connect the energy storage device to the power conversion device, thereby continuing to supply power to devices such as the water pump. Furthermore, in this invention, the turbine blades are located below the second water outlet, meaning the water driving the turbine blades to generate electricity is filtered water. This helps prevent impurities and pollutants in the filtered water from entangled in the turbine blades, avoiding damage and improving the overall stability and reliability of the aquarium device.

[0016] Thus, the aquarium device provided by this utility model can continuously ensure the filtration and circulation of water in the aquarium body even in special scenarios such as power outages, while improving resource utilization and reducing electricity costs, thereby avoiding the death of aquatic organisms due to power outages and other problems.

[0024] This utility model provides a fish tank device, including a fish tank body 1, a water pump 2, a power conversion device, a pipe 3, a filter 4, a hydroelectric power generation device 5, an energy storage device, and a first switch; the hydroelectric power generation device 5 includes turbine blades and a generator 51 connected by a rotating shaft, the generator 51 is electrically connected to the energy storage device, and the energy storage device is electrically connected to the power conversion device through the first switch. The water pump 2 is located in the aquarium body 1 and is electrically connected to the power adapter. The water pump 2 is provided with a first outlet 21 for exporting the water to be filtered from the aquarium body 1. The pipe 3 is provided with a first port 31 connected to the first outlet 21 and a second port 32 for importing the water to be filtered into the filter 4. The filter 4 is used to convert the water to be filtered into filtered water. The filter 4 is provided with a second outlet 41 for exporting the filtered water. The turbine blades are located below the second outlet 41 and above the aquarium body 1.

[0025] Specifically, such as Figure 1 As shown, the aquarium device in this example includes an aquarium body 1, a water pump 2, a power conversion device, pipes 3, a filter 4, a hydroelectric power generation device 5, an energy storage device, and a first switch (the power conversion device, energy storage device, and first switch are also included). Figure 1 (Not shown in the image). In this embodiment, the aquarium body 1 refers to the container for holding water and aquatic organisms (such as fish), and is the main part of the entire aquarium setup, providing living space for the aquatic organisms. The water pump 2 is located inside the aquarium body 1 and is electrically connected to a power adapter. The water pump 2 has a first outlet 21 for exporting the water to be filtered from the aquarium body 1. Powering the water pump 2 with electricity from the power adapter drives it to draw water from the aquarium body 1 through the first outlet 21. In this embodiment, the pipe 3 can have an annular cross-section, and its diameter can be determined based on the diameter of the first outlet 21 of the water pump 2, thus effectively transferring the water to be filtered pumped by the water pump 2 to the filter 4. The first port 31 of the pipe 3 is connected to the first outlet 21 of the water pump 2, and the second port 32 is adapted to guide the water to be filtered into the filter 4, thereby achieving directional water flow.

[0026] In this embodiment, the energy storage device (e.g., a battery) is used to store the electrical energy generated by the hydroelectric power generation device 5, and can be a lead-acid battery, etc. In this embodiment, the first switch can be a manual switch (e.g., a push-button switch, a slide switch, a rotary switch, etc.). Taking a push-button switch as an example, when the operator controls the push-button switch to the closed state, the energy storage device can supply power to the power conversion device. Conversely, when the operator controls the push-button switch to the open state, the energy storage device stops supplying power to the power conversion device. The power conversion device referred to in this embodiment is used to connect to the power supply and supply power to the electrical device (e.g., the water pump 2). It can include multiple input terminals and multiple output terminals. For example, in a normal power consumption scenario, its input terminals can be mainly connected to the mains power, and its output terminals can be connected to the electrical device such as the water pump 2 to supply power to the electrical device. In special scenarios, such as a power outage or when the energy stored in the energy storage device is sufficient to drive the aquarium device for a period of time, its input terminals can be electrically connected to the energy storage device through the first switch to supply power to the electrical device.

[0027] Optionally, in this embodiment, the energy storage device may be provided with an energy indicator structure or a power usage indicator structure, thereby displaying corresponding charging and discharging parameters such as power level and duration.

[0028] In one embodiment, the filter 4 can purify the passing water (i.e., the water to be filtered), converting it into filtered water to remove impurities and contaminants. For example, in this embodiment, the filter 4 can be a filter device with multiple layers of filter cotton and activated carbon. The filter 4 is provided with a second outlet 41 for discharging the filtered water, and the turbine blades are located below the second outlet 41 and above the aquarium body 1. For example, in this embodiment, the turbine blades and the generator 51 are connected by a shaft, allowing the generator 51 to be fixed on a bracket, and the turbine blades, coaxially arranged with the generator 51, to be positioned between the second outlet 41 of the filter 4 and the top surface of the aquarium body 1 via the bracket.

[0029] In this embodiment, the water pump 2 is located in the aquarium body 1 and electrically connected to the power adapter. The water pump 2 has a first outlet 21 for exporting the water to be filtered from the aquarium body 1. The pipe 3 has a first port 31 connected to the first outlet 21 and a second port 32 for importing the water to be filtered into the filter 4. Thus, when the power adapter is connected to, for example, mains power, it can drive the water pump 2 to import the water to be filtered from the aquarium body 1 into the filter 4 through the pipe 3 for filtration, thereby converting the water to be filtered into filtered water. The filter 4 has a second outlet 41 for exporting the filtered water. The turbine blades are located below the second outlet 41 and above the aquarium body 1. Therefore, the filtered water exported from the second outlet 41 can flow back into the aquarium body 1 after passing through the turbine blades. At this time, the filtered water enters the aquarium body from above, which can play a certain role in oxygenation. During this process, the filtered water can drive the turbine blades to rotate under the action of gravity, thereby converting the kinetic energy of the water flow into electrical energy through the generator 51 connected to the rotating shaft. In this embodiment, the generator 51 is electrically connected to the energy storage device. After the hydroelectric power generation device 5 converts kinetic energy into electrical energy, the electrical energy is stored in the energy storage device, thus realizing energy recovery and improving the energy utilization efficiency of the entire aquarium device. Simultaneously, in this embodiment, the energy storage device is electrically connected to the power conversion device via a first switch. In scenarios such as a power outage, the operator can control the first switch to close, connecting the energy storage device to the power conversion device to continue supplying power to devices such as the water pump 2. Furthermore, in this embodiment, the turbine blades are located below the second water outlet 41, meaning the water driving the turbine blades to generate electricity is filtered water. This helps prevent impurities and pollutants in the filtered water from entangled in the turbine blades, avoiding damage and improving the overall stability and reliability of the aquarium device.

[0030] Thus, the aquarium device provided in this embodiment can continuously ensure the filtration and circulation of water in the aquarium tank 1 even in special scenarios such as power outages, while improving resource utilization and reducing electricity costs, thereby avoiding problems such as the death of aquatic organisms due to power outages.

[0031] Optionally, the generator 51 also includes a housing 52 for accommodating the turbine blades; one end of the housing 52 is provided with a first inlet 53 connected to the second outlet 41, and the other end is provided with a third outlet 54; the turbine blades are located between the first inlet 53 and the third outlet 54.

[0032] In this embodiment, the generator 51 also includes a housing 52 for accommodating the turbine blades. A first water inlet 53 is located at one end of the housing 52 and is connected to the second water outlet 41 of the filter 4. It serves as the inlet for filtered water to enter the housing 52 and impact the turbine blades, determining the position and direction of the water flow into the hydroelectric power generation device 5, and playing a role in protecting and guiding the water flow. At the other end of the housing 52, the filtered water that has impacted the turbine blades flows out from here and returns to the aquarium tank 1. Since the turbine blades are located between the first inlet 53 (connected to the second outlet 41) and the third outlet 54, and the turbine blades are located below the second outlet 41, it can be seen that in the vertical direction (i.e., the Z-axis direction), the height of the turbine blades is less than the height of the first inlet 53 (located at one end of the housing 52) and greater than the height of the third outlet 54 (located at the other end of the housing 52). The housing 52 of the hydroelectric power generation device 5 provides a relatively enclosed space for the turbine blades, so that the filtered water can impact the turbine blades in a specific path under the action of gravity, which not only improves the power generation efficiency, but also helps to avoid the splashing of filtered water during the rotation of the turbine blades, thus facilitating continuous circulation.

[0033] Optionally, the aquarium body 1 is a shell structure with a first opening end on the top surface, and the bottom end of the third water outlet 54 is located above the first opening end.

[0034] In this embodiment, the aquarium body 1 is a shell structure with a first opening on the top surface, which facilitates the collection of filtered water introduced through the third outlet 54. The bottom end of the third outlet 54 is located above the first opening, providing space for the filtered water to fully contact with air during the backflow process, which helps to increase the dissolved oxygen content of the filtered water, thereby reducing the operating time of the aeration device and further reducing the power cost of the aquarium device.

[0035] Optionally, the filter 4 is a housing structure with a second opening end on the top surface, the second opening end being located below the second port 32 and above the second outlet 41.

[0036] In this embodiment, the filter 4 is a housing structure with a second opening on its top surface, providing ample space for placing or replacing the filter material and for introducing the water to be filtered. The second port 32 on the pipe 3 for introducing the water to be filtered into the filter 4 is located above the second opening of the filter 4, i.e., as shown... Figure 1As shown, the position of the second port 32 in the vertical direction (i.e., the Z-axis direction) is higher than the second opening end, which helps ensure that the water to be filtered can flow smoothly into the filter 4 under the action of gravity, thus improving the filtration efficiency. Meanwhile, the second outlet 41 on the filter 4, which is used to discharge the filtered water, is located below the second opening end, meaning that the position of the second opening end in the vertical direction is higher than the second outlet 41. This allows the filtered water to flow smoothly out of the filter 4 under the action of gravity and into the subsequent hydroelectric power generation device 5, which helps improve the circulation filtration efficiency.

[0037] Optionally, the aquarium device also includes a second switch; the generator 51 is electrically connected to the energy storage device via the second switch.

[0038] In this embodiment, the aquarium device also includes a second switch, through which the generator 51 is electrically connected to the energy storage device. The operator can control the opening and closing of the second switch to decide whether to store the electrical energy generated by the generator 51 in the energy storage device. Users can decide independently whether to store the electrical energy generated by the generator 51 in the energy storage device based on actual needs (such as battery level, current power usage, etc.). For example, when the energy storage device is fully charged and continuing to charge may affect its lifespan, the circuit can be cut off via the second switch to avoid overcharging and effectively extend the lifespan of the energy storage device. Conversely, when the energy storage device is low on power, the operator can close the second switch to promptly store the electrical energy generated by the generator 51 in the energy storage device, ensuring stable operation of the equipment and thus achieving on-demand energy storage.

[0039] Optionally, the aquarium device also includes a solar power generation unit and a third switch; the solar power generation unit is electrically connected to the power conversion unit via the third switch.

[0040] In this embodiment, the aquarium device also includes a solar power generation device (such as a solar panel) and a third switch. The solar power generation device is electrically connected to the power conversion device via the third switch. The operator can flexibly decide whether to activate the solar power generation device to supply power to the aquarium device by controlling the opening and closing of the third switch. For example, during periods of good light conditions, the third switch can be closed to supply power to electrical devices such as water pump 2 via the solar power generation device. At this time, the first switch can also be opened and the second switch closed to store the electrical energy converted by the hydroelectric power generation device in the energy storage device. During periods of poor light conditions, the first switch can be closed and the third switch opened to supply power to electrical devices such as water pump 2 via the electrical energy stored in the energy storage device. This helps reduce the aquarium device's dependence on traditional mains power, achieves diversified energy utilization, and thus effectively reduces the electricity cost of the aquarium device.

[0041] Optionally, the aquarium device also includes a fourth switch; the water pump 2 is electrically connected to the power adapter via the fourth switch.

[0042] In this embodiment, the aquarium device also includes a fourth switch; the water pump 2 is electrically connected to the power adapter via the fourth switch, and the operator can control the opening and closing of the water pump 2 by controlling the fourth switch, thereby achieving on-demand water filtration based on the actual water quality and the needs of aquatic organisms in the aquarium. This avoids unnecessary energy waste and extends the service life of the water pump 2.

[0043] Optionally, the aquarium device also includes a heating device and a fifth switch; the heating device is electrically connected to the power conversion device via the fifth switch.

[0044] In this embodiment, the heating device refers to a device (such as an electric heater) used to regulate the water temperature in the aquarium. The heating device can be installed below the third water outlet 54, where the water flow is relatively large, which helps to ensure that the heat is evenly distributed throughout the entire aquarium body 1. In this embodiment, the heating device is electrically connected to the power adapter via a fifth switch. The operator can control the heating device to turn on and off by controlling the fifth switch, thereby flexibly controlling the start and stop of the heating device according to the habits of the aquatic organisms in the aquarium and the actual water temperature, thus achieving on-demand regulation of the water temperature.

[0045] Optionally, the aquarium device also includes an aeration device and a sixth switch; the aeration device is electrically connected to the power conversion device via the sixth switch.

[0046] In this embodiment, the oxygenation device refers to a device used to increase the dissolved oxygen content of the water to be filtered in the aquarium tank 1. For example, the oxygenation device may include an air pump, an air hose, and an air stone. The air pump is connected to the air stone located inside the aquarium tank 1 via the air hose. The air stone disperses the air delivered by the air pump into tiny bubbles, increasing the contact area between the air and the water and improving the dissolved oxygenation efficiency. In this embodiment, the aquarium device also includes an oxygenation device and a sixth switch. The oxygenation device is electrically connected to a power adapter via the sixth switch. The operator can control the on / off state of the sixth switch to turn the oxygenation device on and off according to actual needs, thereby avoiding unnecessary waste.

[0047] Optionally, the power adapter is provided with at least one extended output port.

[0048] In this embodiment, the extended output port refers to a port that can be connected to other electrical equipment besides the water pump 2, heating device, and aeration device to supply power to them. For example, equipment such as lighting and disinfection devices can be connected to the extended output port to meet the diverse needs of operators.

[0049] Optionally, the circuit diagram of the fish tank device in this embodiment is as follows: Figure 2 As shown, Figure 2In this diagram, PV represents a solar power generation device, WT represents a hydropower generation device, A represents a power conversion device, BAT represents a battery (i.e., an energy storage device), M1 represents water pump 2, M2 represents an oxygenation device, R represents a heating device, USB represents an extended output port, K1 represents the first switch, K2 represents the second switch, K3 represents the third switch, K4 represents the fourth switch, K5 represents the fifth switch, and K6 represents the sixth switch. In this embodiment, the structures of the second to sixth switches are basically the same as the first switch, and will not be described again here.

[0050] It should be understood that in this embodiment, the water pump, aeration device and heating device and other electrical devices are mainly powered by mains power or solar power generation. The operator can flexibly use the electrical energy stored in the battery to power the electrical devices in special power use scenarios such as power outages or when the battery has enough stored power to drive the aquarium device for a period of time.

[0051] For example, during periods of good lighting, the operator can close the third switch to connect the solar power generation device to the power adapter, and simultaneously close the fourth switch to connect the water pump 2 to the power supply, thereby drawing the water to be filtered from the aquarium 1 into the filter 4 for filtration. Furthermore, the operator can close the second switch to connect the generator 51 to the battery, storing the electrical energy generated by the hydroelectric generator 51 during the filtration process in the battery.

[0052] During periods of low light, the operator can close the first switch to connect the battery to the power adapter, while simultaneously disconnecting the third and second switches to prevent the solar power generation device and hydroelectric power generation device 5 from affecting the stability of the battery power supply. In this way, this embodiment can flexibly control the states of each switch to achieve on-demand power supply and on-demand energy storage, thereby improving energy utilization efficiency and effectively reducing the electricity cost of the aquarium device.

[0053] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
