The cold air in the cooling box (5) is conducted to the protection device body (1) through the contact surface between the lower surface of the cooling box (5) and the protection device body (1), thereby cooling the air in the protection device body (1) and the storage battery (13), thereby ensuring the working stability of the storage battery (13). When the coolant needs to be replaced, the original coolant is poured out through the discharge port (24), and then the new coolant is added into the guide tube (27) from the feed port (25); When the storage battery (13) needs to be stored, the fixing bolts (15) on the storage plate (16) that needs to store the storage battery (13) are taken out from the holes and holes (19) provided in the sliding plate (17), and the storage plate (16) that needs to store the storage battery (13) is slid into the sliding groove (18) provided in the sliding plate (17) and slides out of the protection device body (1), and then the storage battery (13) is placed on it, and the storage plate (16) is slid into the sliding groove (18) provided in the sliding plate (17) and slides into the protection device body (1), and the fixing bolts (15) on the storage plate (16) that needs to store the storage battery (13) are taken out from the holes and holes (19) provided in the sliding plate (17), and then the storage battery (13) is placed on it, and then ... then the fixing bolts (15) on the storage plate (16) that needs to store the storage battery (13) are taken out from the holes and holes (19) provided in the sliding plate (17), and then the fixing bolts (15) on the storage plate (16) that needs to store the storage battery (13) are taken out from the holes and holes (19) provided in the sliding plate (17), and then the fixing bolts (15) on the storage plate (16) that needs to store the storage battery (13) are taken out The bottom end of the fixed bolt (15) passes through the hole provided in the sliding plate (17) and is inserted into the hole (19) to fix the position of the storage plate (16), thereby fixing the position of the storage battery (13). The rotation of the rotating rod (29) in the annular sliding plate (30) is driven by the bolt (11) to drive the rubber pad (12) to approach the storage battery (13) until it contacts the storage battery (13). The fixed soft pad (14) is convenient to cooperate with the rubber pad (12) to fix the position of the storage battery (13), thereby reducing the contact between the storage battery (13) and the inner wall of the protective device body (1); When it is necessary to take out the storage battery (13), the fixing bolts (15) on the storage plate (16) on which the storage battery (13) is placed are taken out from the holes and holes (19) provided in the sliding plate (17), so that the storage plate (16) on which the storage battery (13) is placed slides in the sliding groove (18) provided inside the sliding plate (17) and slides out of the protective device body (1), so that the storage battery (13) can be conveniently taken out; when the storage plate (16) slides out of the protective device body (1), it can be cleaned and maintained.
