Description

Technical Field

[0001] This invention relates to the field of microbial fuel cell technology, specifically to a wall-mounted microbial power generation flowerpot. Background Technology

[0002] Microbial fuel cells are devices that use microorganisms to directly convert the chemical energy in organic matter into electrical energy. The basic principle is that in the anaerobic environment of the anode chamber, organic matter decomposes under the action of microorganisms and releases electrons and protons. Electrons are effectively transferred between the biological components and the anode through a suitable electron transport medium and are transferred to the cathode through an external circuit to form an electric current. Protons are transferred to the cathode through a proton exchange membrane. The oxidant gains electrons at the cathode and is reduced to combine with protons to form water. However, since the power generation capacity of microorganisms is very small, related research is mostly used in large-scale greening environments in municipalities.

[0003] For example, Chinese utility model patent CN208273692U discloses a modular plant microbial power generation green wall. The plant microbial fuel cell system includes plants, flower pots, cathode electrodes, anode electrodes, wires, and metal sheets; the energy storage circuit includes a power management module and energy storage elements; the electrical appliance system is set as an external electrical appliance; this utility model collects and utilizes the electrical energy generated by plant microorganisms, achieving the purpose of energy supply and environmental beautification.

[0004] Compared to the aforementioned patents and existing technologies, current microbial power generation flower pots still have the following shortcomings during use:

[0005] 1. It is difficult to accurately control the water level in the microbial power generation pot. Existing microbial power generation pots are difficult to control the water level. When the water level exceeds the anode, it is easy to destroy the anaerobic environment, resulting in a decrease in power generation efficiency or failure. In addition, the position of the cathode in existing microbial power generation pots is fixed and cannot follow the change of water level. When the water level changes, the contact surface of the cathode submerged in water is not constant, which makes it impossible to maintain a stable balance between the cathode and water and air during the reduction reaction, thus reducing the stability of power generation. Although the method of completely submerging the cathode can easily achieve the stability of power generation, the oxygen supply depends only on the flow of water or the oxygen production of plant photosynthesis, resulting in low power generation efficiency.

[0006] 2. In order for microbial fuel cells to activate the load, multiple sets of microbial power generation pots are often required. Existing microbial power generation pots are mostly placed on the ground, which has low space utilization and is difficult to maintain. At the same time, when multiple pots are to be connected to activate the load together, there is a problem of difficult wiring. Summary of the Invention

[0007] The purpose of this invention is to address the problems of difficulty in accurately controlling the water level in the microbial power generation pot, which can easily lead to a decrease in power generation efficiency or failure, the inability to maintain a stable balance between water and air during the reduction reaction at the cathode, thus reducing the stability of power generation, the low power generation efficiency of the completely submerged cathode method, the low space utilization rate and difficulty in maintenance of existing microbial power generation pots, and the difficulty in wiring when multiple pots are connected to activate the load together. This invention provides a wall-mounted microbial power generation pot.

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution: A wall-mounted microbial power generation flowerpot includes a pot body with an anaerobic chamber at the front and an aerobic chamber at the rear. The bottoms of the anaerobic and aerobic chambers are connected by a through-slot, and an ion exchange membrane is installed in the through-slot to achieve ion exchange. The cultivation pot is placed inside the anaerobic chamber, and an anode assembly is installed inside the cultivation pot. The cathode assembly is located inside the aerobic chamber. A cover plate is locked to the top of the aerobic chamber at the rear of the pot body. An electrical output terminal is fixedly installed in the center of the cover plate, and the anode and cathode assemblies are electrically connected to the electrical output terminal. An inlet pipe is installed on one side of the anaerobic chamber at the front of the pot body, and an outlet pipe is installed on one side of the aerobic chamber at the rear of the pot body. The outlet pipe is located on the side opposite to the inlet pipe and is lower than the inlet pipe.

[0009] Furthermore, a front partition is fixedly connected to the bottom of the anaerobic chamber on the front side of the basin, and a rear partition is fixedly installed at the bottom of the aerobic chamber on the rear side of the basin. The front and rear partitions are aligned front to back, and the height of the rear partition is greater than the height of the front partition.

[0010] Furthermore, the height of the water outlet pipe is above the bottom end face of the culture basin, but below the anode assembly in the culture basin. An overflow pipe is also installed on one side of the aerobic chamber at the rear of the basin. The height of the overflow pipe is flush with the top end face of the rear partition, above the water outlet pipe and below the anode assembly in the culture basin.

[0011] Furthermore, the anode assembly includes a carbon felt placed inside the culture pot and a support frame that fixes and electrically connects the carbon felt. After planting in the culture pot, the carbon felt is located at the root system in the soil. The support frame passes backward through the culture pot and then through the gap between the anaerobic chamber and the aerobic chamber of the pot, and is fixed by bolts. The center of the support frame is electrically connected to the power output terminal through an insulated wire.

[0012] Furthermore, the power output terminals are provided with plugs on both sides for connecting conductive parts, so as to realize the series connection between power output terminals on different basins to superimpose the output voltage.

[0013] Furthermore, the cathode assembly includes a float plate, which is slidably connected to the interior of the aerobic chamber on the rear side of the basin via a rear partition plate. The carbon cloth tube is inserted vertically through the float plate and is hollow in design. It is fixedly inserted into the float plate by an interference fit. The connector is located above the carbon cloth tube and is fixed and electrically connected to each carbon cloth tube. The center of the bottom of the connector is electrically connected to the power output terminal via an insulated wire.

[0014] Furthermore, a fixing plate is provided on the rear side of the basin, and a snap-fit ​​groove is provided at the front end of the fixing plate. A fixing block is fixedly connected to the rear end of the basin. The fixing plate is snapped into the rear end of the basin by the snap-fit ​​groove and the fixing block. Hooks are symmetrically hinged on the left and right sides of the bottom of the fixing plate.

[0015] Furthermore, the cover plate has downwardly extending protrusions at both ends. After the cover plate is engaged with the aerobic chamber at the rear of the basin, a ventilation groove is left between the rear basin and the cover plate.

[0016] Furthermore, it also includes a wire mesh, which is fixedly installed on the surface of the building wall, and the basin is suspended from the wire mesh by hooks.

[0017] Furthermore, when the basins are suspended, the inlet and outlet pipes on adjacent basins are distributed in a crisscross pattern, allowing the inlet and outlet pipes of adjacent basins to be connected on both sides via connecting pipes. The inlet pipe of the uppermost basin is connected to a water injection pipe, and the outlet pipe of the lowermost basin is connected to a drain pipe.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention, through the design of the inlet pipe at the anaerobic chamber and the outlet pipe at the aerobic chamber of the basin, combined with the overflow pipe, can keep the water level in the basin submerged at the bottom of the breeding basin without submerging the anode assembly, thus ensuring the stability of the anaerobic environment and avoiding a decrease or failure in power generation efficiency. Furthermore, through the design of the cathode assembly, the float plate moves with the water level to keep the ratio of the carbon cloth tube submerged in water to exposed air constant, thereby achieving a stable balance in the contact between the carbon cloth tube and water and air during the reduction reaction at the cathode, and thus improving the stability of power generation.

[0020] 2. This invention, through the design of the fixing plate and hook on the back of the basin, enables the basin to be suspended by installing a wire mesh on the building wall, which is beneficial for space utilization. After suspension, it can achieve uniform water filling, which is conducive to continuous water filling in conjunction with drip irrigation, reducing the difficulty of maintenance. At the same time, it is convenient to connect the wires in series to superimpose the output voltage for use, and it is convenient to manage the wires with the wire mesh. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] A wall-mounted microbial power generation flowerpot according to a preferred embodiment of the present invention will be described in detail below: Example 1

[0040] like Figures 1-8 As shown, a wall-mounted microbial power generation flowerpot includes a pot body 1. The pot body 1 has an anaerobic chamber 101 on the front side and an aerobic chamber 102 on the rear side. The bottom of the anaerobic chamber 101 and the aerobic chamber 102 are connected by a through groove 103, and an ion exchange membrane is provided at the through groove 103 to realize ion exchange. A cultivation pot 3 is placed inside the anaerobic chamber 101. An anode assembly 4 is installed inside the cultivation pot 3, and a cathode assembly 5 is disposed inside the aerobic chamber 102. A cover plate 6 is limited and snapped onto the top of the aerobic chamber 102 on the rear side of the pot body 1. An electrical output terminal 7 is fixedly installed in the center of the cover plate 6, and the anode assembly 4 and the cathode assembly 5 are electrically connected to the electrical output terminal 7 respectively. An inlet pipe 8 is installed on one side of the anaerobic chamber 101 on the front side of the pot body 1, and an outlet pipe 9 is installed on one side of the aerobic chamber 102 on the rear side of the pot body 1. The outlet pipe 9 is located on the side opposite to the inlet pipe 8, and the outlet pipe 9 is lower than the inlet pipe 8 (it should be noted that, as Figures 4-5 As shown, the left and right sides of the breeding basin 3 taper downwards and will not adhere to the inner wall of the basin 1, so that the water inlet pipe 8 located on one side of the basin 1 can inject water into the basin 1.

[0041] like Figures 4-5 , Figure 12 As shown, a front partition 10 is fixedly connected to the bottom of the anaerobic chamber 101 on the front side of the basin 1, and a rear partition 11 is fixedly installed on the bottom of the aerobic chamber 102 on the rear side of the basin 1. The front partition 10 and the rear partition 11 are aligned front to back, and the height of the rear partition 11 is greater than the height of the front partition 10.

[0042] like Figures 6-8 , Figures 11-12As shown, the water outlet pipe 9 is positioned above the bottom end face of the culture basin 3, but below the anode component 4 within the culture basin 3. Therefore, through the design of the water outlet pipe 9, the water level inside the basin 1 can submerge the bottom of the culture basin 3, thereby creating an anaerobic environment inside the culture basin 3; however, the water level will not submerge the anode component 4, ensuring the stability of the anaerobic environment.

[0043] An overflow pipe 12 is also installed on one side of the aerobic chamber 102 at the rear of the basin 1. The height of the overflow pipe 12 is flush with the top end face of the rear partition 11, located above the outlet pipe 9 and below the anode assembly 4 in the aquaculture basin 3. The overflow pipe 12 design allows for individual drainage of water in a single basin 1 when there is heavy rainfall or rapid water filling and the outlet pipe 9 cannot drain water in time, preventing water level rise. The design of the overflow pipe 12 being above the outlet pipe 9 and below the anode assembly 4 in the aquaculture basin 3 ensures that drainage will not occur when the water level in the basin 1 does not exceed the outlet pipe 9, while also preventing the anode assembly 4 from being submerged. The design of the overflow pipe 12 being flush with the top end face of the rear partition 11 prevents the water level from exceeding the top end face of the rear partition 11, thus preventing the float 501 from detaching from the rear partition 11.

[0044] like Figures 4-5 , Figure 9 As shown, the anode assembly 4 includes a carbon felt placed inside the cultivation pot 3, and a support frame that fixes and electrically connects the carbon felt. After planting in the cultivation pot 3, the carbon felt is located at the root system in the soil. The support frame extends backward through the cultivation pot 3, then through the gap between the anaerobic chamber 101 and the aerobic chamber 102 of the pot body 1, and is fixed with bolts. The center of the support frame is electrically connected to the power output terminal 7 via an insulated wire. In the anaerobic environment, organic matter decomposes under the action of microorganisms, releasing electrons and protons, which are then transported to the power output terminal 7 through the carbon felt.

[0045] like Figures 5-6 As shown, the power output terminal 7 has plugs on both sides for connecting conductive parts, so as to realize the series connection between the power output terminals 7 on different basins 1 to superimpose the output voltage.

[0046] like Figure 8 , Figure 10As shown, the cathode assembly 5 includes a float plate 501, which is slidably connected to the interior of the aerobic chamber 102 on the rear side of the basin 1 via a rear partition plate 11. A carbon cloth tube 502 is inserted vertically through the float plate 501, and the carbon cloth tube 502 has a hollow design. It is fixedly inserted to the float plate 501 using an interference fit. A connector 503 is located above the carbon cloth tubes 502, fixed to each carbon cloth tube 502 and electrically connected. The center of the bottom of the connector 503 is electrically connected to the power output terminal 7 via an insulated wire. The hollow design of the carbon cloth tube 502 increases the contact area between the carbon cloth tube 502 and the water. Through the action of the float plate 501, when the water level inside the aerobic chamber 102 changes, the carbon cloth tube 502 can move up and down with the float plate 501, thus maintaining a constant ratio of the carbon cloth tube 502 submerged in water to exposed to air. The carbon cloth tube 502 is inserted using an interference fit. With the deformation of the carbon cloth tube 502, the ratio of the carbon cloth tube 502 being submerged in water to being exposed to air can be adjusted by moving the carbon cloth tube 502 up and down according to different usage scenarios or materials.

[0047] like Figures 2-5 As shown, the cover plate 6 has downwardly extending protrusions at both ends. After the cover plate 6 is engaged with the aerobic chamber 102 on the rear side of the basin 1, a ventilation groove 15 is left between the rear basin 1 and the cover plate 6. This allows air to enter the aerobic chamber 102 through the ventilation groove 15, ensuring the oxygen content of the air in the aerobic chamber 102.

[0048] Working principle:

[0049] When in use, plants are planted inside the cultivation pot 3, so that the soil covers the carbon felt of the anode component 4.

[0050] After planting, when watering, the water enters the anaerobic chamber 101 through the inlet pipe 8, and then enters the aerobic chamber 102 through the channel 103. The outlet pipe 9 is located on the opposite side of the inlet pipe 8 and is designed to be lower than the inlet pipe 8. The water can flow between the anaerobic chamber 101 and the aerobic chamber 102 and flow out from the outlet pipe 9. Therefore, the water level inside the basin 1 can be maintained at the height of the outlet pipe 9.

[0051] The design of the water outlet pipe 9, which is located above the bottom end face of the culture basin 3 but below the anode component 4 in the culture basin 3, allows the water level inside the basin 1 to submerge the bottom of the culture basin 3, thereby creating an anaerobic environment inside the culture basin 3. However, the water level will not submerge the anode component 4, ensuring the stability of the anaerobic environment.

[0052] In an anaerobic environment, organic matter decomposes under the action of microorganisms and releases electrons and protons. The carbon felt enhances the power generation performance and delivers electrons to the power output terminal 7. The load is connected in series through the sockets on both sides of the power output terminal 7, and the electrons are delivered to the cathode assembly 5 through the external circuit.

[0053] By partially immersing the carbon cloth tube 502 in the cathode assembly 5 in water, under the influence of dissolved oxygen in the water and oxygen in the air, and with the migration of protons, electrons are gained at the cathode assembly 5 and a reduction reaction is carried out to generate water.

[0054] By designing the float plate 501 in the cathode assembly 5, the carbon cloth tube 502 can move up and down with the float plate 501 when the water level inside the aerobic chamber 102 changes, thus keeping the ratio of the carbon cloth tube 502 submerged in water to exposed to air constant. This achieves a stable balance in the contact between the carbon cloth tube 502 and water and air during the reduction reaction at the cathode, thereby improving the stability of power generation. Example 2

[0055] Furthermore, such as Figure 3 , Figures 11-15 As shown, a fixing plate 13 is provided on the rear side of the basin 1. A snap-fit ​​groove 1301 is provided at the front end of the fixing plate 13. A fixing block 104 is fixedly connected to the rear end of the basin 1. The fixing plate 13 is snapped onto the rear end of the basin 1 through the engagement of the snap-fit ​​groove 1301 and the fixing block 104. Hooks 14 are symmetrically hinged on the left and right sides of the bottom of the fixing plate 13.

[0056] It also includes a wire mesh 16, which is fixedly installed on the surface of the building wall, and the basin 1 is suspended on the wire mesh 16 by a hook 14.

[0057] When the basin 1 is suspended, the water inlet pipe 8 and water outlet pipe 9 on the upper and lower adjacent basins 1 are distributed in a cross pattern, so that the water inlet pipe 8 and water outlet pipe 9 can be connected to each other on the left and right sides through the connecting pipe 17. The water inlet pipe 8 of the uppermost basin 1 is connected to the water injection pipe 18, and the water outlet pipe 9 of the lowermost basin 1 is connected to the drain pipe 19.

[0058] Working principle:

[0059] To ensure that the microbial fuel cell meets the load requirements and large-scale planting is needed, a wire mesh 16 can be fixed to the wall of the building first. Then, the hooks 14 on the back fixing plate 13 of the pot 1 can be used to hang the pot 1 on the wire mesh 16, which is beneficial to the use of space.

[0060] After the basin 1 is suspended, the water inlet pipes 8 and water outlet pipes 9 on the upper and lower adjacent basins 1 are arranged in a crisscross pattern to connect the water inlet pipes 8 and water outlet pipes 9 between the upper and lower adjacent basins 1 through the connecting pipe 17. Therefore, when filling with water, water only needs to be filled through the water inlet pipe 18 at the water inlet pipe 8 of the uppermost basin 1. When the water level in the basin 1 reaches the water outlet pipe 9, it will enter the next basin 1 through the connecting pipe 17 until all the vertical basins 1 reach the water level corresponding to the water outlet pipe 9. The water will then be discharged from the drain pipe 19 at the water outlet pipe 9 of the lowermost basin 1.

[0061] It should be added that, to further improve convenience, the water inlet pipe 18 at the top horizontal position of the basin 1 can be connected to allow for unified water injection. Simultaneously, to ensure sufficient water volume inside the basin 1, it is also beneficial to use drip irrigation to continuously supply water at a low flow rate to the basin 1 through the water inlet pipe 18, thereby maintaining the water level inside the basin 1 and ensuring the continuous effectiveness of the microbial fuel cell.

[0062] The design of the plugs on both sides of the power output terminal 7 allows adjacent power output terminals 7 at the same height to be connected in series directly by plugging in wires. This facilitates the superposition of output voltages through series connection and allows for cable management through the combination of cable ties and wire mesh 16. Example 3

[0063] like Figure 16 As shown, unlike Embodiment 1, in municipal greening, the building wall surface to be planted is not necessarily flat. For example, the surface of bridge piers and elevated bases are the most common surfaces for vertical greening. However, through the hinged design of the hook 14, the hook 14 can be flipped backward. When the wire mesh 16 is fixed to the curved wall surface, the pot 1 can also be suspended by the hook 14 and the wire mesh 16.

[0064] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
