Description

Technical Field

[0002] A nuclear power plant refers to a facility that converts nuclear energy into electrical energy through appropriate devices. A nuclear power plant uses a nuclear reactor to replace the boiler of a thermal power plant. The nuclear fuel undergoes a special form of "combustion" in the nuclear reactor to generate heat, which converts nuclear energy into thermal energy to heat water to produce steam. A nuclear power unit is a basic power generation unit consisting of a reactor and its supporting steam turbine generator unit, as well as the systems and facilities required to maintain their normal operation and ensure safety.

[0003] In the current existing technology, the existing battery packs are powered on and stored on the surface of the support frame, and a fault alarm device is used to detect the battery packs on the surface of the support frame.

The inner wall of the first honeycomb tube 19, the second honeycomb tube 191 and the third honeycomb tube 192 and the top surface of the heat-absorbing expansion material 20 are movably sleeved with a hollow spacer block 21, and the top surface of the hollow spacer block 21 is A small power supply group 22 is arranged on the surface, a protective shell 25 is fixedly installed on the top surface of the extension shell 17, a small signal transmitter 26 is arranged on the top surface of the protective shell 25, an insulating soft layer 23 arranged on the top surface of the small power supply group 22 is fixedly connected to the inner wall surface of the protective shell 25, and a power-on cone thorn 24 is arranged on the top inner wall surface of the protective shell 25 and the top surface of the insulating soft layer 23, and one end of the power-on cone thorn 24 passes through the insulating soft layer 23 and is connected to the output end of the small power supply group 22.

When the hot air flow passes through the surface of the rock wool board 18, the hot air flow flows inside the expansion shell 17, and cooperates with the hot air flow to contact with the first group of honeycomb tubes 19, the second group of honeycomb tubes 191 and the third group of honeycomb tubes 192 inside the expansion shell 17, so that the external heat source passes through the first group of honeycomb tubes 19, the second group of honeycomb tubes 191 and the third group of honeycomb tubes 192 and contacts with the internal heat-absorbing expansion material 20, and then the different heat-absorbing expansion materials 20 inside the first group of honeycomb tubes 19, the second group of honeycomb tubes 191 and the third group of honeycomb tubes 192 expand slightly after absorbing the heat source. The heat-absorbing expansion material 20 moves upward at a vertical angle under the position limitation of a group of honeycomb vertical cylinders 19, and then the hollow pad block 21 on the top surface of the heat-absorbing expansion material 20 lifts and pushes the insulating soft layer 23, so that the power-carrying cone thorns 24 on the top surface of the insulating soft layer 23 are in contact with the power-carrying cone thorns 24 on the bottom surface of the protective shell 25, and then the power-carrying cone thorns 24 in contact are energized by the small power supply group 22, and the power-carrying cone thorns 24 will also energize the small signal transmitter 26.

The staff can use the alarms of the small signal transmitters 26 in different areas to cool down or extinguish the fire in the area as soon as possible, thereby achieving the effect of utilizing the alarms of the small signal transmitters 26 in different areas to enable the staff to perform maintenance on the area as soon as possible, avoiding the situation where the fault alarm device can only provide warnings to employees when a fire or abnormal high temperature occurs in the battery pack, and the employees need to check one by one, which causes a waste of time and further expands the harm.

[0034] Furthermore, if Figure 1 - Figure 2 As shown, a protective shell 111 is arranged on the back of the insulating shell 11, one end of the cable plug 131 is arranged on the inner wall of the protective shell 111, a pull-out machine 112 is arranged on the top surface of the insulating shell 11, and a transparent isolation door 113 fixedly connected to the output end of the pull-out machine 112 is swingably sleeved on the front of the insulating shell 11.

[0035] When the insulating casing 11, the pull-out machine 112 and the transparent isolation door 113 provided by the present invention are in use, the heat-absorbing expansion materials 20 inside the first group of honeycomb columns 19, the second group of honeycomb columns 191 and the third group of honeycomb columns 192 are all made of different materials, namely polyvinylidene chloride, polyimide and polysulfone PSU, and the heat-absorbing expansion temperatures of polyvinylidene chloride, polyimide and polysulfone PSU are 40 degrees, 60 degrees and 70 degrees respectively. When the temperature around the battery pack 14 is abnormal, the material inside the heat-absorbing expansion material 20 will absorb heat sources to different degrees. When the heat sources exceed the internal heat expansion threshold of the heat-absorbing expansion material 20 one by one, the employees will receive three alarms in sequence, and the battery pack 14 will be in a state of abnormal temperature. The safe operating temperature range is usually between -40℃ and 80℃. When the battery reaches 70 degrees, an alarm will be sounded, and the gap between 70 degrees and 80 degrees is used as the reaction time of the staff, so as to achieve the effect of segmented control of the temperature of the battery pack, and then to remind the employees in advance, to avoid the battery pack spontaneous combustion, the time is too short and the speed is too fast, and the employees cannot be reserved The reaction time or the time is too short to miss the best rescue time. When the battery pack 14 inside the insulating shell 11 spontaneously ignites and catches fire, the puller 112 is used to pull and extend the transparent isolation door 113, so that the battery pack 14 inside the insulating shell 11 can quickly dissipate heat and cool down.

[0036] Furthermore, if Figure 1 , Figure 3 - Figure 4 and Figure 7 - Fig. 9 As shown, a docking sleeve 132 is provided on the outer surface of the isolation sleeve 13, a docking strip is provided on the outer surface of the isolation sleeve 13, a limiting groove movably sleeved on the outer surface of the docking strip is provided on one side surface of the docking sleeve 132, a limiting groove 134 is provided on the inner wall surface of the isolation sleeve 13 and the docking sleeve 132, a positioning block 135 is movably sleeved on the inner wall surface of the limiting groove 134, a semicircular anti-skid pad 137 is provided on the inner wall surface of the positioning block 135, a motor 138 is fixedly installed on the two side surfaces of the isolation sleeve 13 and the docking sleeve 132, and the inner wall of the semicircular anti-skid pad 137 A cable plug 131 arranged on the input end of one side of the battery pack 14 is movably sleeved on the surface, a latch rod 136 is arranged on the outer surface of the positioning block 135, and a signal receiver 133 is arranged on the two side surfaces of the isolation shell 13 and the docking shell 132. The inner wall surface of the insulating shell 11 and the two side edge positions of the electric threaded rod 12 are fixedly connected to the limit rod 121, and the output end of the electric threaded rod 12 is threadably sleeved with a slider 122, and the inner wall surface of the slider 122 is movably sleeved on the outer surface of the limit rod 121, and the outer surface of the detection alarm 123 is detachably mounted on the surface of the slider 122.

[0037] When the isolation casing 13, cable plug 131, docking casing 132, signal receiver 133, positioning block 135 and motor 138 provided by the present invention are in use, when the host receives the alarm transmitted by the small signal transmitter 26 for the second time, the signal receiver 133 on the surfaces of both sides of the isolation casing 13 and the docking casing 132 will also receive the signal transmitted by the staff at the same time, and then energize the motor 138 on the inner wall surface of the isolation casing 13 and the docking casing 132, so that the motor 138 can rotate at any time, and under the inspection of the staff or the sensor of the fault alarm device clearly finds that there is obvious When smoke, abnormally high temperature or personnel send the final alarm, the powered motor 138 rotates rapidly, causing the positioning block 135 on the outer surface of the motor 138 to move toward the two side surfaces, thereby pulling and peeling off the cable plug 131 on the outer surface of the positioning block 135, and quickly cutting off the power to the battery pack 14, thereby achieving the effect of quickly cutting off the power to the battery pack 14 in case of spontaneous combustion or the possibility of spontaneous combustion, thereby reducing the power supply inside the battery pack 14 to avoid thermal runaway, and preventing the battery pack 14 from being powered on when the battery is burning, thereby causing the current to increase sharply, generating a large amount of heat, and causing thermal runaway of the battery.

[0038] The working principle provided by the present invention is as follows: the electric threaded rod 12 is rotated by itself so that the electric threaded rod 12 and the slider 122 on the outer surface of the limit rod 121 move back and forth on the side of the battery pack 14. When the slider 122 moves, it cooperates with the detection alarm 123 and the exhaust fan 16 on the inner wall of the insulating shell 15 to absorb the gas on the outer surface of the detection alarm 123 and the insulating shell 15, and then absorbs the heat source emitted by the battery pack 14. When the hot air flow passes through the surface of the rock wool board 18, The hot air flows inside the expansion shell 17, and the hot air contacts with the first group of honeycomb tubes 19, the second group of honeycomb tubes 191, and the third group of honeycomb tubes 192 inside the expansion shell 17, so that the external heat source passes through the first group of honeycomb tubes 19, the second group of honeycomb tubes 191, and the third group of honeycomb tubes 192 and contacts with the internal heat-absorbing expansion material 20, and then the different heat-absorbing expansion materials 20 inside the first group of honeycomb tubes 19, the second group of honeycomb tubes 191, and the third group of honeycomb tubes 192 are slightly heated after absorbing the heat source. The expanded heat-absorbing expansion material 20 moves upward at a vertical angle under the position limit of a group of honeycomb vertical cylinders 19, and then the hollow pad block 21 on the top surface of the heat-absorbing expansion material 20 lifts and pushes the insulating soft layer 23, so that the energized cone thorns 24 on the top surface of the insulating soft layer 23 are in contact with the energized cone thorns 24 on the bottom surface of the protective shell 25, and then the energized cone thorns 24 after contact are energized through the small power supply group 22, and the energized cone thorns 24 will also energize the small signal transmitter 26, and the energized small signal transmitter 26 will transmit signals to the host. If the temperature of the environment around the battery pack is abnormal, the three small signal transmitters 26 will light up in turn as the temperature gradually rises, and the host will send an alarm to the staff. The staff can cool down or extinguish the fire in the area as soon as possible through the alarms of the small signal transmitters 26 in different areas, so as to achieve the effect of using the alarms of the small signal transmitters 26 in different areas to enable the staff to maintain the area as soon as possible;

[0039] The heat-absorbing expansion materials 20 inside the first group of honeycomb columns 19, the second group of honeycomb columns 191 and the third group of honeycomb columns 192 are all made of different materials, namely polyvinylidene chloride, polyimide and polysulfone PSU, and the heat-absorbing expansion temperatures of polyvinylidene chloride, polyimide and polysulfone PSU are 40 degrees, 60 degrees and 70 degrees respectively. When the temperature around the battery pack 14 is abnormal, the material inside the heat-absorbing expansion material 20 will absorb heat sources to different degrees. When the heat sources exceed the internal heat expansion threshold of the heat-absorbing expansion material 20 one by one, the employees will receive three alarms in sequence. The safe operating temperature range of the battery is usually between -40°C and 80°C. When the battery reaches 70 degrees, an alarm will be issued, and the gap between 70 degrees and 80 degrees is used as the reaction time of the staff, so as to achieve the effect of segmented control of the temperature of the battery pack and thus prompt the employees in advance.

[0040] When the host receives the alarm transmitted by the small signal transmitter 26 for the second time, the signal receivers 133 on the surfaces of both sides of the isolation shell 13 and the docking shell 132 will also receive the signal transmitted by the staff at the same time, and then energize the motor 138 on the inner wall of the isolation shell 13 and the docking shell 132, so that the motor 138 can rotate at any time. When the staff checks or the sensor of the fault alarm device clearly finds obvious smoke, abnormally high temperature or the personnel sends a final alarm, the energized motor 138 rotates rapidly, so that the positioning block 135 on the outer surface of the motor 138 moves toward the surfaces on both sides, and then the cable plug 131 on the outer surface of the positioning block 135 is pulled and peeled off, and then the battery pack 14 is quickly powered off, so as to achieve the effect of quickly powering off the battery pack 14 in case of spontaneous combustion or with the premise of spontaneous combustion, thereby reducing the power supply inside the battery pack 14 to avoid thermal runaway.
