[0043] The protection component includes a connecting frame 201, an electric push rod 1 202, a mounting frame 203, a protection net 204, an electric push rod 205, a connecting plate 206, a collection box 207 and a support plate 208; two connecting frames 201 are fixed to the inner rear wall of the frame 1; each connecting frame 201 is bolted with an electric push rod 1 202; the telescopic part of each electric push rod 1 202 is commonly fixed with the mounting frame 203; a protection net 204 is rotatably connected to the mounting frame 203; two electric push rods 205 are bolted to the opposite sides of the two receiving seats 4; the telescopic parts of all the electric push rods 205 are commonly fixed with a connecting plate 206; a collection box 207 is fixed to the connecting plate 206; two support plates 208 are fixed to the inner side of the collection box 207; the two support plates 208 are rotatably connected to another protection net 204; each protection net 204 is provided with a space avoidance groove 20401.

[0044] Furthermore, in order to increase the service life of the protection net 204, the protection net 204 is made of a high temperature resistant alloy.

[0045] The working steps of this embodiment are:

[0046] The following rotations are from front to back, from top to bottom, and from right to left.

[0047] The first step is to place the mineral insulated cable performance testing device at the required position when in use;

[0048] In the second step, the operator connects an external power supply to all components that need to be driven by electricity, adds a large amount of water into the frame 1, and makes the water level higher than the collection box 207, and then places three cables (it should be noted that the cable is a cable in which two sections of cables are connected to each other) in the placement grooves 4001 of the two receiving seats 4, and then controls the output shafts of the two motors 6 to drive the two pressing plates 5 to rotate counterclockwise, so that the two pressing plates 5 rotate ninety degrees and return to the corresponding receiving seats 4. At this time, the limiting grooves 5001 of the two pressing plates 5 cooperate with the placement grooves 4001 of the receiving seats 4 to clamp the two ends of the three cables, and then the operator picks up the power clamps 8 in turn to clamp the corresponding cable conductors respectively, and the power supply on the tester 7 supplies power to the cable conductors through the power clamps 8;

[0049] Then, the telescopic parts of the two electric push rods 202 are controlled to be pushed out, driving the mounting frame 203 and the upper protective net 204 to move downward together. At the same time, the telescopic parts of the four electric push rods 205 are controlled to contract, driving the connecting plate 206, the collecting box 207, the supporting plate 208 and the lower protective net 204 to move upward together. When the collecting box 207 rises from the frame 1, the collecting box 207 is filled with water, so that the two protective nets 204 are merged to form a complete cylinder. The mounting frame 203 and the two supporting plates 208 form a complete cylindrical frame. At this time, the air avoidance groove 20401 of the lower protective net 204 is opposite to the flamethrower 10, and then the operator grabs the two sliding doors 2 and moves them to the opposite sides to merge. At this time, the two testers 7 are controlled to be turned on to continuously test the three cables. Then, the flamethrower 1 is controlled. 0 is turned on, and the flame ejected from the flamethrower 10 will pass through the air avoidance groove 20401 of the protective net 204, burn the joints of the three cables, and test the fire resistance and service life of the cables in a fire, until the circuit of the cable is disconnected in the burning of the fire. During the detection process, the current sensor and voltage sensor in the tester 7 are used to measure the current intensity and voltage level of the cable, and the analog signal collected by the current sensor and the voltage sensor is received by the data acquisition module and converted into a digital signal, and then the signal is transmitted to the computer to process the collected signal to judge the status of the cable, such as whether there is a fault and whether the warning threshold is reached. When the cable is disconnected, the signal received by the current sensor and the voltage sensor in the tester 7 is disconnected, and the flamethrower 10 is automatically controlled to be closed, and the burning of the cable stops.

[0050] It should be noted that, during the inspection, the joint of the cable can be moved to face the flamethrower 10, and the fire resistance test of the joint of the cable can be carried out to test the service life of the mineral insulated cable at the joint in a fire. Because the internal structure of the normal mineral insulated cable is inconsistent with that of the mineral insulated cable at the joint, it is necessary to carry out a fire resistance test on the cable joint.

[0051] Due to the high thermal conductivity of the conductor and the sheath, the heat from the burning of the cable will be conducted to other parts of the cable through the conductor and the sheath. In the prior art, when the cable is fireproofed, the cable is clamped by an electric clamping component. The heat transferred from the conductor and the sheath is only lower than the combustion temperature of the center of the cable (i.e., 600°C-700°C). When the high temperature is transferred to the electric clamping component, it is easy to cause damage to the electric clamping component, affecting the normal operation of the electric clamping component. Therefore, in the process of burning the cable, the two water pumps 101 are controlled to be turned on, and the water in the frame 1 is pumped into the corresponding water pump 101 through the two curved pipes 102, and then transported from the output end of the water pump 101 to the two drain pipes 103, and then transported from the two drain pipes 103 to the corresponding groove 4002 of the receiving seat 4, and the water entering the groove 4002 will also be discharged from several drainage holes. 4003 is discharged. At this time, because the water output of the drain pipe 103 is greater than the drainage of the plurality of drainage holes 4003, the water level in the groove 4002 will gradually rise until the water submerges the three cables. After the water level is slightly higher than the cables, the rotation speed of the water pump 101 is controlled to decrease, so that the water output of the drain pipe 103 is equal to the drainage of the plurality of drainage holes 4003. In this way, the water level in the groove 4002 is always higher than the three cables, so that the cables on the receiving seat 4 are continuously submerged in the water. In this way, the heat on the cables is taken away by the continuously flowing water in the groove 4002, and the heat generated by the burning of the cables is isolated, so as to avoid the heat of the burning of the cables being transferred to the electric clamping components, causing damage to the electric clamping components. It should be noted that the water level can be detected by setting a water level sensor in the groove 4002, and the water pumping amount of the water pump 101 can be controlled by the water level sensor.

[0052] During the fire resistance test on the cable joints, since hot melt adhesive, heat shrink tubing, copper tube and other materials are used when the cables are joined, a large number of flying sparks will be generated when the fire burns the cable joints. The sparks flying around may easily cause damage to the circuits and electrical components inside the rack 1. Therefore, during the burning of the cables, the cylinder formed by the two protective nets 204 is used to intercept the flying sparks to prevent the flying sparks from igniting or damaging the cables and electrical components inside the rack 1.

[0053] The third step, when the fire resistance life test of the cable is completed, the operator closes the two testers 7, opens the two sliding doors 2, and then controls the telescopic parts of the two electric push rods 202 to retract, driving the mounting frame 203 and the upper protective net 204 to move upward together. At the same time, the telescopic parts of all electric push rods 205 are pushed out, driving the connecting plate 206, the collecting box 207, the support plate 208 and the lower protective net 204 to move downward together, so that the two protective nets 204 are automatically separated, and then the two water pumps 101 are controlled to be closed, and no water is transported into the groove 4002. After the water in the groove 4002 completely flows into the frame 1, the operator opens all the power clamps 8 clamping the cable conductors, and then controls the output shafts of the two motors 6 to rotate clockwise, driving the two pressure plates 5 to rotate, so that the two pressure plates 5 no longer clamp the three cables, and the operator takes away the three cables after the test.

[0054] It should be noted that, since the space inside the rack 1 is small, and as the flame sprayed by the flamethrower 10 continues to burn the cable, a large amount of oxygen in the rack 1 will be consumed, and the problem of lack of oxygen and flameout may occur. Therefore, when the flamethrower 10 sprays fire, the four fans 1001 are controlled to turn on and continuously supply air to the rack 1 to provide the necessary conditions for cable burning.

[0055] It should be noted that the water in the rack 1 is filtered through the filter 104 to prevent impurities in the water from entering the water pump 101 and affecting the normal use of the water pump 101 .

[0056] It should be noted that the water in the rack 1 can absorb the heat diffused to the surroundings when the cable burns, thereby preventing the temperature in the rack 1 from being too high and affecting the normal use of the internal electrical components of the rack 1 .

[0057] It should be noted that when the water in the rack 1 is polluted, the sewage in the rack 1 can be drained away through the sewage pipe 1002 and then the water can be replaced.

[0058] Example 2

[0059] On the basis of Example 1, Figure 4-Figure 6As shown, a cleaning assembly is also included, and the two support plates 208 are connected to the cleaning assembly; the cleaning assembly includes a fixed plate 301, a transmission roller 302, a cleaning roller 303, a spur gear 304 and a motor 2 305; each support plate 208 is fixedly connected to a fixed plate 301; the lower parts of the two fixed plates 301 are connected to the transmission roller 302 in rotation; the outer surface of the transmission roller 302 is provided with a plurality of protrusions, and the transmission roller 302 is in contact with the outer side of the protective net 204; the upper parts of the two fixed plates 301 are connected to the cleaning roller 303 in rotation, and the outer surface of the cleaning roller 303 is in contact with the inner side of the protective net 204; the transmission roller 302 and the cleaning roller 303 are each fixedly connected to a spur gear 304, and the two spur gears 304 are meshed; the right fixed plate 301 is bolted to the motor 2 305, and the output shaft of the motor 2 305 is fixedly connected to the transmission roller 302; the motor 2 305 is a waterproof motor.

[0060] Furthermore, in order to ensure the cleaning effect of the attachments on the inner side of the protection net 204, the outer surface of the cleaning roller 303 is provided with a plurality of metal bristles.

[0061] It also includes an air suction component, which is connected to the mounting plate 3; the air suction component includes a vacuum pump 401, a telescopic tube 402, an air suction hood 403 and a connecting pipe 404; the vacuum pump 401 is bolted to the rear of the upper surface of the mounting plate 3; the input end of the vacuum pump 401 is connected to the telescopic tube 402; the air suction hood 403 is embedded on the mounting frame 203; the inner arc surface of the air suction hood 403 is provided with a plurality of strip holes 40301 distributed at equal intervals; the telescopic tube 402 passes through the mounting frame 203, and the telescopic tube 402 is connected to the air suction hood 403; the input end of the vacuum pump 401 is connected to the connecting pipe 404; the connecting pipe 404 passes through the mounting plate 3 and extends into the frame 1.

[0062] The working principle of this embodiment is:

[0063] Since the cable contains hot melt adhesive and heat shrink tube, when the hot melt adhesive and heat shrink tube burn, harmful gases will be generated due to the influence of the materials. As the burning time of the cable increases, the harmful gases generated will also increase. After the sliding door 2 is opened, the harmful gases in the rack 1 are easily absorbed by the operator, causing harm to the operator's body. Therefore, during the burning of the cable, the harmful gases generated will float upward. At this time, the vacuum pump 401 is controlled to be turned on, and the telescopic tube 402 and the suction hood 403 will generate suction, and the plurality of strip holes 4030 of the suction hood 403 will be sucked out. 1. The harmful gas floating upward is sucked away, and the harmful gas is allowed to pass through the vacuum pump 401 and discharged from the connecting pipe 404. At this time, the lower part of the connecting pipe 404 is in water, so the harmful gas discharged from the connecting pipe 404 will enter the water, and the harmful substances in the harmful gas are degraded by the water, and the harmful substances in the gas are separated to prevent the harmful substances from being sucked away by the operator and endangering the health of the operator. In this way, the water used to block the heat of the cable is also used to degrade the harmful gas generated during the cable combustion test, and there is no need to set up an additional purification structure to purify the harmful gas.

[0064] Since the flying sparks are intercepted by the protective net 204, the impurities carried by the sparks will adhere to the inner side of the protective net 204. As the protective net 204 intercepts more sparks, the more impurities there are on the inner side of the protective net 204. If there are too many impurities attached to the inner side of the protective net 204, the mesh holes on the protective net 204 will be blocked, causing the suction hood 403 to be unable to absorb the harmful gas. Therefore, when the flamethrower 10 is closed and the protective net 204 has not yet separated, the output shaft of the control motor 2 305 rotates clockwise, driving the transmission roller 302 and the spur gear 304 below to rotate clockwise, and the spur gear 304 below drives the spur gear 304 above and the cleaning roller 303 to rotate counterclockwise. When the transmission roller 302 rotates, the two protective nets 204 are driven on the mounting frame 203 and the two support plates through the several protrusions on the transmission roller 302. The two protective nets 204 are rotated in the cylindrical frame formed by 208, and the two protective nets 204 are gradually passed through the water in the collecting box 207. The two protective nets 204 are cooled down by the water in the collecting box 207, and the attachments on the inner side of the protective nets 204 are soaked. At the same time, the cleaning roller 303 also rotates counterclockwise continuously, and the attachments on the inner side of the protective nets 204 are brushed by the metal bristles on the cleaning roller 303. After the two protective nets 204 rotate for one circle and the wet attachments on the protective nets 204 are brushed clean, the output shaft of the control motor 2 305 stops rotating to prevent the attachments on the inner side of the protective nets 204 from clogging the mesh and affecting the absorption of harmful gases. In this way, the water used to block the heat of the cable and degrade the harmful gases is also used to cool the protective net 204 and soak the attachments on the inner side of the protective net 204 to facilitate their removal.
