[0025] For reference Figs. 1-3 The high-temperature lead-acid storage battery protection device 100 provided by the present application comprises a screw rod 14 and two groups of fixing assemblies. The two groups of fixing assemblies are oppositely arranged, and the fixing assembly comprises a side plate 10, a bottom plate 11 and two connecting plates 12. The bottom plate 11 and the connecting plates 12 are connected with the side plate 10, and the two connecting plates 12 are located on the two sides of the side plate 10. The connecting plate 12 is fixedly provided with an ear plate 13. The screw rod 14 is arranged between the two groups of fixing assemblies, and the screw rod 14 is slidably connected with the two ear plates 13 in the two groups of fixing assemblies. The screw rod 14 is provided with a fastener 15, and the fastener 15 is located on the side away from each other of the two ear plates 13 in the two groups of fixing assemblies. The fastener 15 is threadedly connected with the screw rod 14.

[0026] The connecting plate 12 and the ear plate 13 can be integrally bent and formed, that is, the ear plate 13 is at a certain angle compared with the connecting plate 12, preferably perpendicular to each other. The ear plates 13 on the two connecting plates 12 are parallel to each other. In this way, the overall structure of the connecting plate 12 and the ear plate 13 is reliable, and the connection reliability of the screw rod 14 and the two ear plates 13 is improved.

[0027] The two groups of fixing assemblies are symmetrically arranged, and the high-temperature lead-acid storage battery 20 to be fixed is arranged between the two groups of fixing assemblies. In use, the bottom of the high-temperature lead-acid storage battery 20 is in contact with the top of the bottom plate 11, the two groups of fixing assemblies are pushed towards the high-temperature lead-acid storage battery 20, the fixing assemblies slide along the lead screws 14 through the lug plates 13, and finally the two side plates 10 are attached to the sides of the high-temperature lead-acid storage battery 20. By tightening the fasteners 15 on the lead screws 14, the fasteners 15 are tightly pressed against the lug plates 13, so that the two side plates 10 firmly fix the high-temperature lead-acid storage battery 20. The lead screws 14 are slidably connected to the two lug plates 13 in the two groups of fixing assemblies, so that the distance between the two groups of fixing assemblies is adjustable, suitable for storage batteries 20 of various shapes and sizes, and capable of improving the utilization rate of the protection device and reducing the experimental cost.

[0028] Please refer to Figs. 1-3 The lug plate 13 is provided with a through hole (not marked in the figure), and the lead screw 14 passes through the through hole and is slidably connected to the lug plate 13 through the through hole. The lead screw 14 can be slidably connected to the lug plate 13 through a clearance fit, so that the two groups of fixing assemblies can smoothly slide along the lead screw 14, and the operation is convenient.

[0029] The end of the lug plate 13 away from the connecting plate 12 can be provided with an arc-shaped end face, the center of the arc-shaped end face coincides with the center of the through hole in the lug plate 13, and after the lug plate 13 is connected to the lead screw 14, the force on each position on the end face of the through hole can be maximally ensured to be uniform, thereby further optimizing the structure of the lug plate 13 and improving the connection effect of the lug plate 13 and the lead screw 14.

[0030] Please refer to Figs. 1-3 The side plate 10 and the connecting plate 12 are vertically arranged, the bottom plate 11 is horizontally arranged, and the side plate 10, the connecting plate 12 and the bottom plate 11 form a wall corner structure. In use, the bottom of the high-temperature lead-acid storage battery 20 is in contact with the top of the bottom plate 11, and as the two groups of fixing assemblies slide along the lead screws 14, the two side plates 10 are attached to and fixed to the sides of the high-temperature lead-acid storage battery 20. In this embodiment, the side plate 10, the connecting plate 12 and the bottom plate 11 are connected by welding, and the side plate 10, the connecting plate 12 and the bottom plate 11 can be made of stainless steel.

[0031] Please refer to Figs. 1-3 In this embodiment, the number of lug plates 13 on each connecting plate 12 is three, and accordingly, in the high-temperature lead-acid storage battery protection device 100 provided by the utility model, the number of lead screws 14 is six, and the two ends of each lead screw 14 are slidably connected to the corresponding lug plates 13 in the two groups of fixing assemblies. In this way, when the two groups of fixing assemblies are pushed towards the high-temperature lead-acid storage battery 20 to adjust the distance between the two groups of fixing assemblies, the sliding of the fixing assemblies is more stable. In other embodiments, the number of lug plates 13 on each connecting plate 12 can be two, four or more, and the specific number is not limited.
