[0024] 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 of 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.

[0025] Specific examples are given below.

[0026] like Figure 1-5 As shown, a security DC-DC power supply with spontaneous combustion warning includes a power supply box body 1; a high temperature sensor 11 is installed in the middle of the power supply box body 1; a vertical plate 12 is fixedly connected to the top of the power supply box body 1; two groups of limit members 13 are fixedly connected to the inner wall of the vertical plate 12; a pull rope 14 is fixedly connected to the inner wall of the vertical plate 12, and the pull rope 14 is slidably arranged in the middle of the two groups of limit members 13; a cutter 15 is fixedly connected to the end of the pull rope 14; two groups of slide bars 16 are fixedly connected to the top of the cutter 15, and the slide bars 16 are slidably arranged in the middle of the vertical plate 12; during operation, the staff installs the power supply box body 1 at the designated position and connects them with lines. When the power supply box body 1 is used for a long time and spontaneous combustion occurs due to the difficulty in dissipating the temperature, the high temperature sensor 11 will sound an alarm, and the high temperature sensor 11 will sound an alarm. A cutter 15 with a large gravity is arranged on the top of the power box body 1, so that after the fire source contacts the middle part of the pull rope 14, the middle part of the pull rope 14 will be burned and melted, and at the same time, after the cutter 15 loses the supporting force from the pull rope 14, it will generate downward gravity, and under the action of the two sets of slide bars 16, the cutter 15 moves quickly and cuts off the line at the end of the power box body 1. This step is combined with the cutter 15 to cut off the line at the end of the power box body 1, reducing the spread of fire. It is difficult for staff to arrive at the scene in the first time, so that the wires or connecting lines quickly spread to other parts or adjacent equipment, causing damage to other equipment. At the same time, under the action of the two sets of slide bars 16, the cutter 15 can move horizontally to improve the accuracy of cutting the line.

[0027] like Figure 2 , 3As shown in Figures 5 and 6, the middle part of the vertical plate 12 is slidably connected to the frame 2; the inner wall of the frame 2 is fixedly connected to the filter screen 21; the top of the vertical plate 12 is fixedly connected to two groups of vertical rods 22; the middle part of the vertical rods 22 is rotatably connected to the tooth block 23, and the end of the tooth block 23 is meshed with the middle part of the slide bar 16; the top of the frame 2 is fixedly connected to two groups of racks 24, and the racks 24 are meshed with the other end of the rack block 23; when working, by arranging two groups of vertical rods 22 on the top of the vertical plate 12, when the two groups of slide bars 16 are under the action of gravity and move downward rapidly, the inner groove in the middle part of the slide bar 16 will drive the tooth block 23 to rotate, and the tooth block 23 will rotate. At the same time, the frame 2 can be slid as a whole to the top of the power box body 1, and under the action of the filter 21, the gravel particles accumulated on the top are transferred to the top of the power box body 1, and transferred to the inside of the power box body 1 along the heat dissipation holes. This step, together with the set gravel particles, can block or extinguish the fire source generated by the spontaneous combustion of the power box body 1, further reduce the spread of the fire and the secondary damage to the electronic components inside the power box body 1, and at the same time, the air-permeable filter 21 can improve the uniformity of the transfer of gravel to the top of the power box body 1, and reduce the problem of some gravel only accumulating in the same place, resulting in a smaller area for extinguishing the fire source.

[0028] like Figure 2 and 3 As shown, a plurality of groups of protrusions 3 are fixedly connected to the bottom of the frame 2; a fixing plate 31 is fixedly connected to the end of the vertical plate 12; two groups of elastic plates 32 are fixedly connected to the middle of the fixing plate 31, and the elastic plate 32 and the protrusion 3 are arranged in the same plane; during operation, by arranging the protrusion 3 at the end of the vertical plate 12, when the vertical plate 12 moves toward the top of the power box body 1, under the action of the elastic plate 32, the plurality of protrusions 3 will contact the elastic plate 32 in turn, and generate vibration force after collision, thereby accelerating the falling of the gravel on the top of the filter 21, this step is combined with the provision of a plurality of raised protrusions 3, which can increase the speed of the gravel falling, and more gravel material can be deposited on the top of the filter 21, further increasing the coverage area of ​​the fire area.

[0029] like Figure 4 and 5As shown, a spring column 4 is fixedly connected to the top of the slide bar 16; a counterweight 41 is fixedly connected to the output end of the spring column 4; during operation, the counterweight 41 is arranged on the top of the slide bar 16, so that when the slide bar 16 moves downward, the speed of the cutter 15 can be increased under the overall arrangement of the counterweight 41, and at the same time, the counterweight 41 will pressurize the spring column 4 to retract, and make the counterweight 41 swing up and down on the output end of the spring column 4. This step cooperates with the counterweight 41 to increase the force of the cutter 15 when cutting the line, and reduce the problem that a lot of impurities are accumulated on the surface of the cutter 15, making it difficult to cut directly when cutting the line. The specific elastic spring column 4 allows the cutter 15 to swing slightly up and down after cutting, thereby further improving the stability during cutting.

[0030] like Figure 3 and 4 As shown, two groups of guide plates 5 are fixedly connected to the bottom wall of the vertical plate 12, and the middle part of the guide plate 5 is arc-shaped; the guide plate 5 is located in the middle of the pull rope 14; when working, two groups of guide plates 5 are arranged near the pull rope 14, so that the guide plate 5 can guide the fire source to the position. This step is combined with the guide plate 5 to improve the problem that after the power box body 1 is damaged and a fire source is generated, the fire source is difficult to directly contact the middle part of the pull rope 14, resulting in a low disconnection speed of the pull rope 14.

[0031] like Figure 3 As shown, a connecting rod 6 is fixedly connected to the middle of the elastic plate 32; when working, by arranging the connecting rod 6 on the side wall of the elastic plate 32, one group of elastic plates 32 will drive the other group of elastic plates 32 to move when they are moving. This step cooperates with the connecting rod 6 to improve the synchronization of the bending and resetting of the two, thereby increasing the force of knocking the bottom of the filter 21 and increasing the speed of the gravel falling on the top of the filter 21.

[0032] like Figure 3 As shown, a friction pad 7 is fixedly connected to the middle of the elastic plate 32; during operation, by arranging the friction pad 7 in the middle of the elastic plate 32, when the elastic plate 32 contacts with multiple bumps 3 in sequence, the friction pad 7 will directly contact the surface of the bump 3. This step cooperates with the friction pad 7 to increase the friction force of the elastic plate 32 when contacting the bump 3, reducing the problem of slippage between the two.

[0033] Working principle: After the power box body 1 is installed at the designated position and connected with the lines, when the power box body 1 is used for a long time and the temperature is difficult to dissipate and spontaneous combustion occurs, the high temperature sensor 11 will sound an alarm, and a cutter 15 with a large gravity is arranged on the top of the power box body 1, so that when the fire source contacts the middle part of the pull rope 14, the middle part of the pull rope 14 will be burned and melted, and at the same time, when the cutter 15 loses the support force from the pull rope 14, it will generate downward gravity and burn at the two sets of slide bars 16. Under the action, the cutter 15 moves quickly and cuts off the line at the end of the power box body 1. By arranging two groups of vertical rods 22 on the top of the vertical plate 12, when the two groups of slide bars 16 move downward quickly under the action of gravity, the inner groove in the middle of the slide bar 16 will drive the tooth block 23 to rotate. While the tooth block 23 is rotating, the frame 2 can slide as a whole to the top position of the power box body 1, and under the action of the filter screen 21, the gravel particles accumulated on the top are transferred to the top of the power box body 1 and follow the heat dissipation holes. Transfer to the inside of the power box body 1, by providing a protrusion 3 at the end of the vertical plate 12, when the vertical plate 12 moves toward the top of the power box body 1, under the action of the elastic plate 32, multiple protrusions 3 will contact the elastic plate 32 in turn, and generate vibration force after collision, thereby accelerating the falling of the gravel on the top of the filter screen 21, and by providing a counterweight block 41 on the top of the slide bar 16, when the slide bar 16 moves downward, under the action of the overall arrangement of the counterweight block 41, the descending speed of the cutter 15 can be increased, and at the same time, the counterweight block 41 will pressurize the elastic The spring column 4 retracts and causes the counterweight 41 to swing up and down on the output end of the spring column 4. Two sets of guide plates 5 are provided near the pull rope 14 so that the guide plates 5 can guide the fire source to a certain position. Connecting rods 6 are provided on the side walls of the elastic plates 32 so that when one set of elastic plates 32 moves, it will drive the other set of elastic plates 32 to move. Friction pads 7 are provided in the middle of the elastic plates 32 so that when the elastic plates 32 contact with a plurality of protrusions 3 in sequence, the friction pads 7 will directly contact and work with the surfaces of the protrusions 3.
