[0023] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] A leakage-proof battery energy storage device comprises a protective body 1, a top cover 2 and a protective component 5; the protective body 1 is provided with a protective component 5, the upper end of the protective body 1 is blocked by the top cover 2, and the top cover 2 is provided with a cathode terminal 201 and an anode terminal 202; the protective component 5 comprises a protective shell 502 and a shell top 503; a battery pack 501 is placed in the protective shell 502, the upper end of the protective shell 502 is an open end, and the open end is detachably and fixedly connected to the shell top 503, so that the staff can inspect and maintain it, specifically: one end of the shell top 503 is hinged to one end of the protective shell 502 by a hinge, and the other end of the shell top 503 is detachably and fixedly connected to the other end of the protective shell 502 by a stud 504 and a fastening nut 505; the top cover 503 is prevented from falling off from the protective shell 502 during use, and the battery pack 501 can be inspected and replaced.

[0025] The upper surface of the shell top 503 is provided with a fixing hole 508 through the thickness direction thereof, and a safety valve 507 is installed on the fixing hole 508. The function of the safety valve 507 is to prevent excessive gas pressure from being generated inside the battery pack 501. When gas is generated inside the battery pack 501, if it is not discharged in time, the pressure will continue to rise, which may eventually cause the battery pack to explode or leak. The safety valve 507 can be automatically activated when the pressure inside the battery pack is too high to discharge excess gas, thereby protecting the safety of the battery pack. The safety valve is a prior art, so it is not described in detail.

[0026] The upper surface of the shell top 503 is connected with a pull rod 506. The pull rod 506 facilitates pulling the shell top 503, and then facilitates disassembly and replacement of the internal battery pack 501.

[0027] A handle 3 is fixedly mounted on the upper end of the top cover 2 .

[0028] The rear side of the protective body 1 is provided with a heat sink 4, and both sides of the protective body 1 are provided with a plurality of holes 7 through the wall thickness. When the operating temperature of the battery energy storage is too high, the battery energy storage can be ventilated and cooled through the heat sink 4 and the holes 7, so that the heat of the battery energy storage is quickly reduced.

[0029] An anti-skid pad 6 is provided between the protection component 5 and the inner bottom surface of the protection body 1 , and an anti-skid pattern 601 is provided on the upper surface of the anti-skid pad 6 to ensure increased stability and buffering force during movement.

[0030] A drain port 901 is disposed at the lower end of the side wall of the protection body 1 , and a drain valve 902 is disposed on the drain port 901 .

[0031] A sliding component 8 is slidably disposed at the lower end of the protection body 1 , and the sliding component 8 is arranged in cooperation with the liquid discharge port 901 .

[0032] The sliding assembly 8 includes a collection box 801, a fixing bar 802 and a slide rail 805; the two side walls of the collection box 801 are respectively slidably connected to the protective body 1 through the corresponding slide rails 805 and the fixing bar 802, the slide rail 805 is fixed on the protective body 1, the fixing bar 802 is fixed on the collection box 801 by screws 803, and the fixing bar 802 is slidably set in the corresponding slide rails 805.

[0033] The accumulated liquid inside the device is collected through the drain port 901 and then discharged to the collection box 801 below through the drain valve 902. The collection box 801 can be disassembled by opening the bayonet 804 on the side of the fixing bar 802, so as to avoid the long-term accumulation of rainwater or leaked liquid, which may cause damage to the maintenance staff and damage to the structure itself.
