[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1 An explosion-proof energy storage cable group protection device is shown, comprising:

[0028] An explosion-proof energy storage box 1 is provided with a plurality of mounting frames 11, and a plurality of mounting frames 11 are each provided with a removable energy storage battery 12, a heat sink 14 is each provided on one side of the plurality of mounting frames 11, and a dustproof net 15 is each provided on one side of the plurality of heat sinks 14, and two symmetrical explosion-proof doors 13 are hinged on the explosion-proof energy storage box 1.

[0029] As can be seen from the above, when in use, the multiple energy storage batteries 12 are first pushed into the multiple installation frames 11 in sequence to complete the installation of the multiple energy storage batteries 12, that is, the energy storage batteries 12 are installed in the explosion-proof energy storage box 1, and they are combined to form an integral energy storage cable group, which can meet the various needs of coal mines, and can also be used for other loads that need to continue to operate after unplanned power outages, greatly improving the safety of coal mine operation. Subsequently, the two explosion-proof doors 13 and the explosion-proof energy storage box 1 are closed to provide a good explosion-proof effect for the energy storage batteries 12, enhance the overall service life and have higher safety, and the heat dissipation box 14 can generate wind force inside the installation frame 11, and actually dissipate the heat generated around the energy storage batteries 12, thereby ensuring the protection of the energy storage cable group and enhancing the service life of the energy storage cable group, and the dustproof net 15 can block external dust or debris to prevent dust or debris from entering the heat dissipation box 14, so that the heat dissipation box 14 can operate normally.

[0030] refer to Figure 1-Figure 5 As shown, the protection component 2 is used to quickly disassemble and assemble the dustproof net 15 on the heat dissipation box 14. The protection component 2 includes a mounting frame 21 sleeved on the outside of the dustproof net 15 and two movable grooves 22 symmetrically opened on one side of the heat dissipation box 14. Two symmetrical movable rods 23 are installed on the mounting frame 21, and the two movable rods 23 are inserted into the two movable grooves 22. Both movable rods 23 are provided with a prompting component for prompting them. A clamping block 24 is fixed at one end of one of the movable rods 23, and a clamping groove 25 for inserting the clamping block 24 is opened in one of the movable grooves 22. The mounting frame 21 is provided with a protective component for limiting one of the movable rods 23. 3. The mounting frame 21 is provided with a positioning component 4 for positioning it with the heat sink 14; each prompt component includes a column 26 fixed on one side of the moving rod 23 and an indicator head 27 fixed on the top of the column 26, and the size of the indicator head 27 is adapted to the column 26; the protection component 3 includes a through groove provided on one side of the mounting frame 21 for the moving rod 23 to rotate and a semi-annular groove 31 provided on the outside of the moving rod 23, and a fixing block 32 is fixed in the through groove, and the fixing block 32 is slidably connected with the semi-annular groove 31, and a fixing groove 33 communicating with the inside of the semi-annular groove 31 is provided on the outside of the moving rod 23, and the fixing groove 33 is plugged and fixed with the fixing block 32.

[0031] Through the above technical solution:

[0032] When the dust screen 15 needs to be cleaned regularly, one of the moving rods 23 is pulled to slide along the through groove, and then the connection between the fixed groove 33 and the fixed block 32 is lost, so that the fixed block 32 slides into the semi-annular groove 31, and one of the moving rods 23 loses its limiting effect in the through groove. At this time, one of the moving rods 23 is pulled to slide along one of the moving grooves 22, but the sliding of one of the moving rods 23 drives the clamping block 24 to slide along the clamping groove 25. As one of the moving rods 23 rotates along the through groove, it drives the semi-annular groove 31 and the fixed block 32 to slide, and then the clamping block 24 rotates along the clamping groove 25, and then the column 26 and the indicator head 27 on the moving rod 23 are changed from vertical to horizontal, and the fixed block 32 slides and contacts along the semi-annular groove 31, so that the clamping block 24 is disengaged from the clamping groove 25, thereby pulling the mounting frame 21 to drive one of the moving rods 23 and the clamping block 24 to slide and disengage from the other moving rod 23 along the two moving grooves 22, so that the dustproof net 15 and the heat sink 14 can be quickly disassembled, and the dustproof net 15 can be ensured to be disassembled and cleaned, thereby solving the problem that the existing dustproof net 15 is prone to cleaning dead corners during cleaning, reducing the maintenance difficulty of the device, avoiding overheating of the device, and enhancing the protection device for the safe operation of the energy storage cable group.

[0033] Furthermore, the protective component 3 also includes a spring 35 fixed in the snap-in groove 25 and a baffle 34 fixed at one end of the spring 35, and one side of the baffle 34 is in contact with one side of the snap-in block 24, and a connecting rod 37 is fixed to one end of the baffle 34, and a connecting groove for the connecting rod 37 to be inserted is provided on the heat sink 14 and the mounting frame 21; based on this, when the dust screen 15 is reinstalled, through the setting of the baffle 34, and pulling the moving rod 23 drives the snap-in block 24 to contact the baffle 34 along the snap-in groove 25, the spring 35 is tightened and reset, thereby giving a thrust to one side of the baffle 34, which is used to form a thrust on one side of the snap-in block 24, so that the snap-in block 24 moves slowly along the snap-in groove 25. During this period, the user can be prompted for a short distance to ensure the accuracy and stability of the plug-in and unplugging actions, reduce the safety risks caused by misoperation, and further improve the stability between the mounting frame 21 and the heat sink 14.

[0034] Furthermore, a fixing strip 36 is fixed to the inner bottom wall of the snap-in groove 25, and a sliding groove corresponding to the fixing strip 36 is opened at the bottom end of the baffle 34, and the sliding groove and the fixing strip 36 are slidably connected; based on this, through the setting of the fixing strip 36, the baffle 34 can be guided to move in the snap-in groove 25, avoiding the baffle 34 from being offset when moving, so that the snap-in block 24 and the baffle 34 are in stable contact with each other.

[0035] In addition, refer to Figure 2-Figure 4 as well as Figure 6As shown, the positioning assembly 4 includes a positioning rod 41 fixed on one side of the mounting frame 21 and a positioning cavity 42 opened on one side of the heat sink 14 for the positioning rod 41 to be inserted into, and a stabilizing assembly connecting the positioning rod 41 with the positioning cavity 42 is provided on the positioning rod 41; the stabilizing assembly includes a closing column 44 fixed in the positioning cavity 42 and a plurality of plug-in slots 43 opened at one end of the positioning rod 41, a plurality of plug-in blocks 45 are fixed to one end of the closing column 44, and the plurality of plug-in blocks 45 are clamped and fixed to the plurality of plug-in slots 43.

[0036] Through the above technical solution:

[0037] When the mounting frame 21 is installed on the heat sink 14, the mounting frame 21 is first moved closer to one side of the heat sink 14, and the positioning rod 41 is inserted into the positioning cavity 42 to connect the mounting frame 21 with the heat sink 14, which can ensure the stability of the mounting frame 21 and the heat sink 14. At this time, the positioning rod 41 slides along the positioning cavity 42 toward one end of the closing column 44 under the continuous movement of the mounting frame 21, and then the multiple plug-in blocks 45 and the multiple plug-in slots 43 are clamped and fixed, that is, the positioning rod 41 and the closing column 44 are clamped and fixed, which enhances the stability of the positioning rod 41 in the positioning cavity 42 and prevents the positioning rod 41 from shaking in the positioning cavity 42, so that the mounting frame 21 and the heat sink 14 can be positioned and installed, which can ensure the stability of the mounting frame 21 when installed on the heat sink 14, avoid shaking or offset of the mounting frame 21, reduce the installation difficulty between the mounting frame 21 and the heat sink 14, and ensure a good fit between the mounting frame 21 and the heat sink 14.
