Description

Technical Field

[0001] The utility model relates to the field of conductive performance testing of aluminum anodes, in particular to a simulated loading device for aluminum-air batteries. Background Art

[0002] An aluminum-air power source uses high-purity aluminum as the negative electrode, oxygen as the positive electrode, and potassium hydroxide or sodium hydroxide as the electrolyte to produce a chemical reaction. Existing portable aluminum-air fuel cells insert an aluminum anode plate into an oxygen-permeable housing, inject electrolyte into the housing to generate a discharge reaction, and then weld the aluminum anode to a conductive copper column, connecting it to an upper electrical box, which outputs the electricity through a port. The quality of the weld between the conductive copper column and the aluminum anode significantly affects the aluminum anode's conductivity. Because both copper and aluminum easily form oxides during welding, poorly welded aluminum anodes significantly reduce their conductivity, which in turn weakens the aluminum-air battery's constant-power load capacity.

[0003] In order to quickly test the conductive performance of aluminum anodes, a simulated load test is usually performed. A DC power supply and a DC electronic load are connected in series with the aluminum anode to form a circuit. The DC power supply outputs a specified voltage, and the DC electronic load carries a specified power. The voltage data on the electronic load display during constant power loading is used to determine the load capacity of the aluminum anode. The higher the voltage, the lower the resistance of the aluminum anode and the greater the load capacity.

[0004] However, the existing test lacks a device for fixing the aluminum anode plate. During the test, both the aluminum plate and the conductive copper column need to be connected with wires, which is cumbersome to operate. Utility Model Content

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Example 1:

[0034] like Figures 1 to 7 As shown, this embodiment provides a simulated loading device for aluminum-air batteries, including a device body composed of a front cover 1, a rear cover 2 and a bottom plate 3. A device space is formed in the middle of the device body, and the top of the device space is an open end, and the aluminum anode plate enters the device space from the open end.

[0035] Specifically, the rear cover 2 and the bottom plate 3 are an integral structure, the bottom plate 3 is horizontally arranged and fixedly connected to the lower end of the rear cover 2. The bottom surface of the front cover 1 rests on the bottom plate 3, and the front cover 1 and the rear cover 2 are fixedly connected by corresponding locking components.

[0036] In this embodiment, the locking assembly includes locking holes 4 respectively provided at the left and right positions of the front cover 1 and the rear cover 2 , and locking bolts pass through the locking holes 4 to fix the front cover and the rear cover together.

[0037] Furthermore, the front cover 1 and the rear cover 2 protrude into the installation space at the locking holes 4. The protruding portions are provided with notches 41, forming retaining grooves 5 at the notches when the front and rear covers 1 and 2 are connected. The left and right sides of the aluminum anode plate 6 form a guide and plug-in fit with the retaining grooves 5, allowing the aluminum anode plate 6 to be inserted into the installation space through the retaining grooves. The retaining grooves 5 serve as guides and also as a gauge for the thickness of the aluminum anode plate. Excessively thick aluminum anode plates cannot pass through the retaining grooves.

[0038] The bottom of the device space is also provided with a clamping mechanism, and the aluminum anode plate 6 is matched with the clamping mechanism in a pluggable manner. The back cover 2 is provided with a wire outlet 8, and the wire connected to the clamping mechanism extends from the wire outlet 8 and is connected to the DC power supply.

[0039] The depth of the clamping mechanism should be set to ensure that after the aluminum anode plate 6 is inserted into the device space and clamped and fixed by the clamping mechanism, the conductive copper column 7 above the aluminum anode plate 6 should be exposed relative to the device space to facilitate connection with the electronic load.

[0040] In this embodiment, the clamping mechanism is an elastic copper sheet 9 of an integral structure, including two relatively protruding parts. The bottom of the elastic copper sheet 9 of the integral structure is fixedly connected to the bottom plate 3.

[0041] The fixing method is not limited to gluing or screwing. The screwing method is configured as follows: the bottom of the integral elastic copper sheet 9 is provided with mounting holes, through which screws are passed to securely connect to the base plate 3. An insulating strip 10 is also required above the screws to prevent contact between the aluminum anode plate 6 and the screws.

[0042] In this embodiment, there are two elastic copper sheets 9 of an integral structure and they are arranged symmetrically on the left and right, but only one of them is connected to the DC power supply wire.

[0043] The simulated loading device of the utility model can fix the aluminum anode plate, realize the pluggable power supply of the aluminum anode plate, simplify the operation process of wire connection, and improve test efficiency.

[0044] Example 2:

[0045] like Figures 8 and 9As shown, the difference between this embodiment and the first embodiment is that the clamping mechanism is an elastic copper sheet with a split structure, and the split structure is easy to process.

[0046] The split-structure elastic copper sheet includes two face-to-face elastic copper sheets 11 fixedly mounted on the front cover 1 and the rear cover 2 , respectively. The two elastic copper sheets 11 each have a protruding portion, and the protruding portions of the two elastic copper sheets are arranged opposite to each other.

[0047] During installation, a mounting hole 12 is provided at the lower end of the split-structure elastic copper sheet 11 , and screws pass through the mounting hole 12 to be fixedly connected to the front cover 1 / the rear cover 2 .

[0048] In this embodiment, a group of split-structure elastic copper sheets are arranged in the middle of the device space, and are longer in the left and right directions, so as to achieve a stable clamping of the aluminum anode plate 6 .

[0049] Example 3:

[0050] like Figure 10 This embodiment also discloses a test principle for simulating a loading device.

[0051] The DC power supply, electronic load and simulated load device are connected in series to form the same circuit. The elastic copper sheet in the simulated load device is connected to the negative wire of the DC power supply. The aluminum anode plate is inserted into the simulated load device in a pluggable form. The aluminum anode plate contacts the elastic copper sheet to push the elastic copper sheet open. The elastic copper sheet elastically clamps the aluminum anode. The electronic load is connected to the conductive copper column of the aluminum anode to form an electrical circuit.
