DETAILED DESCRIPTION

[0020] The following is a combination of the appended examples of the present invention Figure 1-5 , the technical solutions in the embodiments of the present utility model are described in detail. Example 1

[0021] like Figure 1-5 As shown, the utility model is a fire protection device for a battery warehouse, comprising a frame 1, a mounting plate 2, a heat dissipation component 3, a clamping component 4 and a monitoring component 5.

[0022] The rack 1 is provided with a plurality of shelves 11, which are evenly distributed in the vertical direction and fixedly connected to the four columns of the rack 1. A slide groove 12 is provided on one side of the shelf 11, and the slide groove 12 extends in the front-to-back direction. The rack 1 is located on the rear side of the fire water tank as a whole. When the temperature of the battery 6 is abnormal, it is convenient to take it out and put it into the fire water tank to avoid serious consequences.

[0023] The monitoring component 5 includes multiple infrared cameras 51 and terminals 52. The infrared camera 51 is fixedly connected to the outer wall of the column of the rack 1. An infrared camera 51 is set above each layer 11. The terminal 52 is fixedly connected to the top of the rack 1. The infrared camera 51 is connected to the terminal 52 by wires. The terminal 52 is also connected to the electrical structure wires of various parts of the mounting plate 2, the heat dissipation component 3 and the clamping component 4. The infrared camera 51 monitors the temperature data of the battery 6 and transmits it to the terminal 52. When the monitored temperature is abnormal, the terminal 52 controls the heat dissipation component 3 corresponding to the battery 6 with the abnormal temperature to enter the cooling working state, accelerate heat dissipation, and delay the occurrence time of thermal runaway of the battery 6. Then the clamping component 4 moves to the top of the layer 11 where the battery 6 with the abnormal temperature is located, and the mounting plate 2 automatically moves outward to move the battery 6 with the abnormal temperature outside the rack 1. The clamping component 4 clamps the battery 6 out. After the mounting plate 2 returns to its original position, the clamping component 4 puts the battery 6 into the fire water tank to prevent the battery 6 from burning or even exploding.

[0024] like Figure 2 As shown, the bottom of the mounting plate 2 protrudes to form a slider 21, and the slider 21 is engaged in the slide groove 12. The mounting plate 2 can move back and forth on the layer plate 11 along the slide groove 12. The first motor 23 used to drive it to move back and forth is fixedly connected to the rear column of the frame 1. The motor shaft of the first motor 23 is fixedly connected to the first screw rod 22. The first screw rod 22 is parallel to the slide groove 12. The first screw rod 22 is located between the front and rear columns of the frame 1 and is threadedly connected to the protruding block on the rear of the mounting plate 2. The first motor 23 is connected to the terminal 52 with a wire. The terminal 52 sends a signal to control the first motor 23 to start, and its motor shaft drives the first screw rod 22 to rotate, driving the mounting plate 2 to move along the direction of the slide groove 12.

[0025] The upper surface of the mounting plate 2 is concave to form a plurality of mounting grooves 24 for placing batteries. The mounting grooves 24 are connected from top to bottom. A thermal conductive seat 25 is fixedly connected inside the mounting grooves 24. The thermal conductive seat 25 is flush with the lower surface of the mounting plate 2. The thermal conductive seat 25 is made of copper with good thermal conductivity. It should be noted that there is a certain distance between the mounting grooves 24 and the slider 21 and they do not interfere with each other.

[0026] like Figure 3 As shown, the heat dissipation component 3 is arranged on one side of the frame 1, away from the driving part of the mounting plate 2. The heat dissipation component 3 includes a heat dissipation cavity 31 with openings at both ends. The heat dissipation cavity 31 is fixedly connected to the outer wall of the column of the frame 1. One end of the heat pipe 32 extends into the heat conducting sheet 33. The heat conducting sheet 33 is made of copper with good thermal conductivity. The heat conducting sheet 33 is fixedly connected to the layer plate 11, and in a stable state, the heat conducting sheet 33 fits tightly with the heat conducting seat 25. When the temperature of the battery 6 is abnormal, it will quickly be conducted from the heat conducting seat 25 to the heat conducting sheet 33, and further conducted to the heat pipe 32, and flush with the upper surface of the layer plate 11. The other end of the heat pipe 32 extends into the heat dissipation cavity 31 and is connected to the heat dissipation sheet 34. The heat dissipation area is increased by the heat dissipation sheet 34.

[0027] It should be noted that part of the heat pipe 32 extends into the heat dissipation cavity 31, and part of it is located outside the heat dissipation cavity 31. The infrared camera 51 monitors the temperature value of the exposed part of the heat pipe 32 and uses this as data to determine whether the temperature is abnormal.

[0028] The heat dissipation cavity 31 is open at the front and rear ends, and fans 35 are fixedly connected to the openings at both ends to form an air duct in the front-to-back direction, with air entering from the front end and exiting from the rear end. A fine water mist nozzle 38 for spraying fine water mist for heat dissipation is connected to a fire branch pipe 37, which is fixedly connected to the top of the heat dissipation cavity 31. The fine water mist nozzle 38 extends into the interior of the heat dissipation cavity 31 and is located above the heat sink 33. Each heat sink 33 corresponds to a fine water mist nozzle 38. The fire branch pipe 37 is connected to the fire main pipe 36, which is fixedly connected to the outer wall of the rear column of the rack 1.

[0029] An electric valve is installed at the connection between the fire branch pipe 37 and the fire main pipe 36. The electric valve and the fan 35 are both connected to the terminal 52. The terminal 52 sends a signal to control the electric valve to open, so that the fine water mist nozzle 38 can spray for cooling. At the same time, the fan 35 is started to form a front and rear heat dissipation duct. The two are superimposed on each other, with high heat dissipation efficiency and good cooling effect.

[0030] like Figure 4-5As shown, the clamping assembly 4 includes a second motor 43 for driving the up and down movement. The second motor 43 is fixedly connected to the top of the frame 1, and its motor shaft is fixedly connected to the second screw rod 42. The second screw rod 42 is arranged between the upper and lower ends of the frame 1 in the vertical direction and is located on the front side of the frame 1. The guide rod 44 is parallel to the second screw rod 42, fixedly connected between the upper and lower ends of the frame 1, and is located on the other side of the front of the frame 1. One end of the sliding block 45 passes through the guide rod 44, and the other end is threadedly connected to the second screw rod 42. The clamping jaw 41 is installed on the sliding block 45.

[0031] Two openings are provided on the sliding block 45, and the clamping jaw 41 includes two L-shaped clamping arms 411. One side of the clamping arm 411 passes through the opening, and the middle position of the side protrudes to the inner and outer sides to form a rotating shaft, so that the clamping arm 411 can be rotatably connected to the opening. The other side of the clamping arm 411 is located above the sliding block 45, and the top of the side protrudes to form a clamping block 412. The end of the clamping block 412 is fixedly connected to the limit block, and slots 414 are provided on both sides of the connecting block 413. The clamping block 412 is clamped into the slot 414, and the slot 414 is larger than the size of the clamping block 412. The clamping block 412 can move a certain distance in the slot 414. The electric push rod 415 is installed on the sliding block 45, and its fixed end is fixedly connected to the sliding block 45, and the movable end is fixedly connected to the bottom center position of the connecting block 413.

[0032] The second motor 43 and the electric push rod 415 are both connected to the terminal 52. After the terminal 52 issues an instruction, the second motor 43 works to drive the second screw rod 42 to rotate, so that the clamping jaw 41 moves to above the layer 11 where the battery 6 with abnormal temperature is located. Then the movable end of the electric push rod 415 moves downward, and the lower wall of the connecting block 413 gradually fits with the upper surface of the horizontal side of the clamping arm 414, and then continues to move downward. Only the lower wall edge of the connecting block 413 fits with the upper surface of the clamping arm 414, and the fitting position gradually approaches the edge of the clamping arm 414, and the opening angle of the vertical side of the clamping arm 414 becomes larger and larger.

[0033] When the mounting plate 2 moves outward, causing the battery 6 with abnormal temperature to move to the outside of the rack 1 and be located directly below the clamping jaw 41, the movable end of the electric push rod 415 moves upward, and the connecting block 413 fits against the lower wall of the limit block, causing the clamping arm 414 to open vertically to one side at an angle that gradually decreases and eventually becomes parallel, clamping the battery 6. The second motor 43 continues to work, moving upward, causing the mounting plate 2 to return smoothly, and then moves downward, and starting the electric push rod 415 again to open the clamping arm 414, placing the battery 6 with abnormal temperature into the fire water tank to avoid serious consequences.

[0034] A method of using a battery warehouse fire protection device in this embodiment is as follows:

[0035] First, the infrared camera 51 monitors the temperature of the heat pipe 32. When the monitored temperature is abnormal, the terminal 52 sends a signal, and the heat dissipation component 3 corresponding to the layer 11 where the battery 6 with the abnormal temperature is located starts to work. The electric valve on the fire branch pipe 37 opens, and the fine water mist nozzle 38 sprays fine water mist to directly reduce the temperature of the heat sink 34. At the same time, the fans 35 at the front and rear ends of the heat dissipation cavity 31 start to work, accelerating the air flow and reducing the temperature of the heat sink 34. The two cooperate with each other, and the cooling effect is obvious, delaying the occurrence of thermal runaway of the battery 6.

[0036] At the same time, the clamping assembly 4 drives the second screw rod 42 to rotate through the second motor 43, so that the clamping claw 41 moves to the top of the layer 11, and the movable end of the electric push rod 415 moves downward, so that the two clamping arms 414 open. Then, the mounting plate 2 moves outward along the slide groove 12 under the rotation of the first screw rod 22 driven by the first motor 23, so that the battery with abnormal temperature is located directly below the clamping claw 41, and the movable end of the electric push rod 415 moves upward, and the two clamping arms 414 clamp the battery 6 inward at the same time.

[0037] The second motor 43 continues to work, the clamping claw 41 clamps the battery 6 and moves upward for a distance. After the mounting plate 2 returns to its original position smoothly, the clamping assembly 4 moves downward and the electric push rod 415 is started to open the clamping arm 414 and put the battery 6 with abnormal temperature into the fire water tank.

[0038] The above embodiments are only for illustrating the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
