[0023] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0024] 1. A safe fire extinguishing mechanism is provided. When the sinking block falls, the rotating gear and the rotating rod are pulled to rotate 90 degrees, and the left splicing plate and the right splicing plate are pulled to rotate. The fire extinguishing sand is no longer sealed and sealed, so that the fire extinguishing sand can quickly fall into the metal box to perform fire extinguishing operations in the metering box. The falling and burying of the fire extinguishing sand can achieve rapid fire extinguishing, prevent the fire in the metering box from spreading outward and causing greater damage to the surrounding environment, and improve the safety of the metering box;

[0025] The folding air cushion is inflated and expanded by the air pump and the air pipe to press down the lifting strip, so that the limit block can be smoothly stuck in the edge of the rotating gear. When a fire occurs, the air pump is powered off, the folding air cushion leaks and shrinks, and the downward pressure on the lifting strip is lost. The extrusion spring plays a resetting role, pushing the lifting strip upward, causing the limit block to shift, and the rotating gear can rotate smoothly to dump the fire extinguishing sand.

[0026] 2. The storage box and the block desiccant placed inside it can absorb water and dry the inside of the sand storage box, preventing the stored fire-fighting sand from absorbing moisture in the air for a long time and causing damp lumps that cannot fall smoothly. The internal situation of the fire-fighting sand can be observed through the transparent observation cylinder. The characteristic of the fire-fighting sand changing color when it is wet can provide great convenience for the staff to judge the dryness and moisture of the stored fire-fighting sand during maintenance and inspection.

[0027] 3. Utilizing the thermal expansion characteristics of the expanded graphite block, it can quickly sense when a fire occurs inside the metering box and generate heat. After the expanded graphite block is deformed by heat, it pushes up the extrusion block, contacts the buffer pad, and squeezes the pressure sensor upward, transmitting the information of the drastic change in heat after the fire occurs inside the metering box to the air pump, which is powered off and the fire extinguishing sand is dumped to extinguish the fire.

[0028] 4. The movable rod can be used to move along the fixed long frame, and the positioning circle block and the positioning hole correspond to each other to position the rotating gear, so that the connecting block is kept more horizontal, and the left splicing plate and the right splicing plate are kept horizontal, fit and sealed, which provides great convenience for the staff to place and install the rotating gear. The position of the left splicing plate and the right splicing plate is determined so that they will not be skewed. After the position of the rotating gear is determined, the lifting strip plate is lowered so that the limit block can be smoothly stuck on the edge of the rotating gear to prevent collision and obstruction caused by position offset.

[0029] 5. A heat insulation protection mechanism is provided. When the electromagnetic block is powered off, the metal block is no longer adsorbed and fixed. The lower flap and the rotating rod rotate, and the counterweight metal strip pulls the folded heat insulation and fireproof cloth to fall and unfold, surrounding the metal box, playing a role of fire prevention and heat insulation, reducing the influence of the heat generated when the metal box is on fire and transferring to the outside to the surrounding equipment. The counterweight metal strip and the adsorption magnetic block are adsorbed and fixed through the protective layer, and the folded heat insulation and fireproof cloth is tightened and fixed to prevent the folded heat insulation and fireproof cloth from shaking and failing to seal and block heat;

[0030] The bonding block rotates with the lower flap to intercept and block the folded heat-insulating and fire-proof cloth when the lower flap is idle. The bonding block is pressed against the control button and no longer contacts the control button when the lower flap flips over. The alarm will send out an alarm when it receives the signal, making it convenient for staff to find the metering box with problems in time.

[0031] To sum up, through the combination of the safe fire extinguishing mechanism and the thermal insulation protection mechanism, the pressure sensor will quickly transmit the signal outward by utilizing the drastic change in heat inside the metering box when a fire occurs, and transmit it to the air pump and the electromagnetic block respectively, and the air pump and the electromagnetic block are powered off at the same time, and the fire extinguishing operation and fire prevention and heat insulation operation are performed in the metering box at the same time to prevent the fire from spreading outward. At the same time, the heat generated by the fire will not be dissipated outward, which makes it safer to use. The foldable thermal insulation and fireproof cloth plays a further fire prevention role after being unfolded. The fire extinguishing sand did not extinguish the fire, and the foldable thermal insulation and fireproof cloth can effectively prevent the fire from spreading outward.

The output end is connected, one end of an extension block 604 is fixedly connected with a fitting block 607, one end of the storage box 601 is fixedly installed with a mounting block 608 at a position corresponding to the fitting block 607, the bottom end of the mounting block 608 is fixedly installed with a control button 609, the bottom end of the mounting block 608 is fixedly installed with a buffer spring 610, one end of the middle part of the storage box 601 is fixedly installed with an alarm 611, the bottom end of the buffer spring 610 is fixedly connected with an extrusion round block, the bottom end of the extrusion round block is fitted with the top of the fitting block 607, the top of the extrusion round block is fitted with the bottom end of the control button 609, and the signal output end of the control button 609 is connected to the alarm The storage box 601 is connected to the signal input end of the alarm 611, the storage box 601 is folded and stacked with a folded heat-insulating fireproof cloth 613, the top of the folded heat-insulating fireproof cloth 613 is fixedly installed with a fixed adhesive strip 612, and the bottom of the folded heat-insulating fireproof cloth 613 is fixedly installed with a counterweight metal strip 614, and the top edge of the base 1 is provided with a mounting groove 615, and the inside of the mounting groove 615 is embedded with an adsorption magnetic block 616, and the top of the adsorption magnetic block 616 is fixedly bonded with a protective layer 617, the fixed adhesive strip 612 is fixedly connected to the top of the storage box 601, and the bottom end of the counterweight metal strip 614 is placed on the top of the lower flap 603, and the counterweight metal strip 614 is fixedly placed on the top of the lower flap 603. The metal strip 614 is located directly above the adsorption magnetic block 616. When the electromagnetic block 606 is powered off, the metal block 605 is no longer adsorbed and fixed. The lower flap 603 and the rotating rod 602 rotate, and the counterweight metal strip 614 pulls the folded heat-insulating fireproof cloth 613 to fall and unfold, surrounding the metal box 2, playing a role of fire prevention and heat insulation, reducing the influence of the heat generated when the metal box 2 is on fire and transferring to the outside to the surrounding equipment, and the counterweight metal strip 614 and the adsorption magnetic block 616 are adsorbed and fixed through the protective layer 617, and the folded heat-insulating fireproof cloth 613 is tightened and fixed to prevent the folded heat-insulating fireproof cloth 613 from shaking and failing to seal and block heat;

[0058] The bonding block 607 is utilized to rotate together with the lower flap 603, and the folded heat-insulating and fire-proof cloth 613 is intercepted and blocked when the lower flap 603 is idle. The bonding block 607 is pressed onto the control button 609, and no longer contacts the control button 609 when the lower flap 603 is turned over. The alarm 611 will send out an alarm when receiving the signal, so that the staff can find the metering box with problems in time.

[0059] The working principle and use process of the present invention are as follows: first, the staff deflects the rotating gear 506 to a certain position, the positions of the positioning hole 521 and the positioning round block 520 correspond, and the movable rod 519 is pushed to move inward along the fixed long frame 518, and the positioning round block 520 is inserted into the positioning hole 521 to position and stabilize the rotating gear 506, so that the rotating rod 505 no longer rotates, and the left splicing plate 502 and the right splicing plate 503 are kept in a horizontal state, fit each other, and contact with the triangular guide plate 504, and the bottom end of the sand storage box 501 is spliced ​​and sealed, and the air pump 517 is started, and the folding inflatable cushion 515 is inflated through the inflation tube 516 to expand it, and the lifting strip plate 513 is squeezed downward, and the squeezing spring 512 is compressed until the limit block 514 is inserted into the edge of the rotating gear 506, the rotating gear 506 is limited and fixed, and the movable rod 519 and the positioning round block 520 are pulled out;

[0060] The staff pours the fire extinguishing sand into the sand storage box 501, and the transparent observation cylinder 526 is inserted into the fire extinguishing sand through the installation circular hole 525, the limiting ring 527 is fitted with the top of the cross mounting frame 524, a large amount of block desiccant 529 is placed in the storage box 528, and the upper flip cover 522 is closed. At the same time, the folded heat-insulating fireproof cloth 613 is folded and pushed into the storage box 601, and the lower flip plate 603 is rotated and fitted to the bottom end of the storage box 601, and the metal block 605 is fitted with the bottom end of the electromagnetic block 606. After the electromagnetic block 606 is energized, it generates magnetic force to adsorb and fix the metal block 605, and the Shudie lower flip plate 603 will not rotate. The fitting block 607 rotates with the lower flip plate 603, contacts the extrusion round block connected to the bottom end of the buffer spring 610, and squeezes the buffer spring 610, so that the top of the extrusion round block contacts the control button 609;

[0061] During the use of the metering box, the staff needs to regularly check the fire-extinguishing sand inside the sand storage box 501. The block desiccant 529 will absorb moisture in the air to keep the air inside the sand storage box 501 dry. The staff opens the upper flip cover 522 and can observe the internal situation of the inserted fire-extinguishing sand through the inner wall of the transparent observation cylinder 526. The fire-extinguishing sand will change color when it is wet. The color can be used to judge whether the internal fire-extinguishing sand is wet, and the block desiccant 529 can be replaced in time.

[0062] During the use of the metering box, if the electrical components 4 or the connecting lines inside the metal box 2 catch fire, the fire will cause the temperature inside the metal box 2 to change drastically and heat up rapidly. The expanded graphite block 531 senses the rising high temperature and deforms and expands upward, pushing the extrusion block 532 upward to squeeze the buffer pad 534, thereby causing pressure on the bottom end of the pressure sensor 533. The pressure sensor 533 transmits a signal to the air pump 517 and the electromagnetic block 606, and both are powered off.

[0063] After the air pump 517 is powered off, the folded air cushion 515 quickly leaks air and shrivels, and no longer squeezes the lifting strip 513. The squeezing spring 512 resets and stretches, and the guide rod 511 and the fixing block 510 start the guiding and stabilizing function, so that the lifting strip 513 is pushed upward, and the limit block 514 rises with it, and no longer limits the rotating gear 506. The fire extinguishing sand in the sand storage box 501 is accumulated on the top of the left splicing plate 502 and the right splicing plate 503, and the limit support is lost. The splicing plate 502 and the right splicing plate 503 are pressed down and rotated by the fire extinguishing sand. At the same time, the gravity of the sinking block 509 pulls the traction rope 508 and the connecting block 507 to rotate. The connecting block 507 rotates from a horizontal position to a vertical position. The rotating gear 506 and the rotating rod 505 rotate ninety degrees. The left splicing plate 502 and the right splicing plate 503 both remain in a vertical state. The fire extinguishing sand inside the sand storage box 501 falls quickly, burying the fire position inside the metal box 2, which plays a role in rapid fire extinguishing.

[0064] At the same time, after the electromagnetic block 606 is powered off, it no longer attracts the metal block 605, the lower flap 603 rotates and deflects downward, the fitting block 607 no longer squeezes the bottom of the control button 609, and the control button 609 loses the squeeze and transmits the signal to the alarm 611, so that it sends out an alarm, which is convenient for the staff to quickly find the metering box on fire, and the bottom of the storage box 601 loses the limit interception of the lower flap 603, and the folded heat-insulating fireproof cloth 613 is pulled down and unfolded by the gravity of the counterweight metal strip 614, and the bottom end of the counterweight metal strip 614 contacts the protective layer 617, and the magnetic block 616 is attracted to isolate The protective layer 617 adsorbs and fixes the counterweight metal strip 614, so that the folded heat-insulating fireproof cloth 613 is stabilized. The protective layer 617 protects the adsorption magnetic block 616 so that it will not be continuously exposed to the external environment. The protective layer 617 is thin and will not affect its magnetic adsorption. After the folded heat-insulating fireproof cloth 613 is unfolded, it surrounds the metal box 2 on all sides, so that the heat generated by the fire inside the metal box 2 will not be transmitted to the outside, preventing it from affecting the surrounding equipment, and playing a further fire prevention role. The fire is not extinguished by the fire-fighting sand, and the folded heat-insulating fireproof cloth 613 can effectively prevent the fire from spreading outward.
