Further, the length of the adjusting groove 22 is the same as the length of the L-shaped groove 23, and the length of the adjusting groove 22 is larger than the diameter of the engaging disc 25, wherein when the back surface of the engaging disc 25 is attached to the back wall of the adjusting groove 22, and the back wall of the engaging block 26 is also attached to the back wall of the L-shaped groove 23, when a worker needs to clean the remaining granular sundries on the object placing plate 4, the electric push rod 29 can be started to extend outwards for generating forward pushing force on the object placing plate 4 until the front surface of the engaging block 26 is attached to the front wall of the L-shaped groove 23, that is, the operation of the electric push rod 29 is stopped, then the electric telescopic rod 28 is started to contract downwards so as to generate downward pulling force on the object placing plate 4, and then the pulling force is transmitted to the position where the two sets of engaging discs 25, so that the two sets of adjusting grooves 22 rotate along the inside, so that the object placing plate 4 is changed from a horizontal placing state to an inclined state, and then the granular sundries on the object placing plate 4 can actively roll down along the surface of the inclined object placing plate 4.
A cabinet door 30 is installed on the front face of the cabinet body 1 through hinges, a through groove 31 is formed in the outer wall of one side of the cabinet door 30, a fixing plate 32 is installed on the outer wall of one side of the cabinet door 30, and a cooling fan 33 is installed on the outer wall of one side of the fixing plate 32.
Two sets of L-shaped embedding strips 34 which are arranged in a front-back mirror image mode are installed on the outer wall of the other side of the cabinet door 30, and a filter plate 35 is installed between the two sets of L-shaped embedding strips 34.
Further, the setting up of logical groove 31 provides the passageway of inside and outside circulation of air for the cabinet body 1 that is the closure state, fixed plate 32 provides comparatively suitable and stable mounted position for radiator fan 33, radiator fan 33 starts the back, its inside power part drives the flabellum and rotates, so as to produce wind-force, then increase the flow velocity of the internal air of cabinet 1, so as to improve the rate that the internal and external air of the cabinet 1 passes through logical groove 31 and locates the exchange, and then reach the radiating effect of cooling, be in the block connected state between filter 35 and two sets of L type gomphosis strips 34, so that filter 35 changes, wherein filter 35 is used for filtering and gets into its inside air outside the cabinet body 1, so as to avoid more floater follow in the air and get into cabinet body 1 inside.
Further, the working steps of the switch cabinet are as follows:
s1, applying a forward pulling force to the movable baffle 20 by a worker, then transmitting the pulling force to the position where the telescopic spring 19 is located so as to stretch the telescopic spring 19, then increasing the distance between the back surface of the movable baffle 20 and the back wall of the N-shaped frame 18, then placing the exchanger in the enclosed space of the movable baffle 20 and the N-shaped frame 18 by the worker, removing the pulling force applied to the movable baffle 20, and then applying a rotating force in a set direction to the limiting screw 21 so as to enable the bottom of the rotating force to extend into the threaded groove arranged on the object placing plate 4;
s2, closing the cabinet door 30, starting the heat dissipation fan 33, driving the fan blades to rotate by the internal power part to generate wind power, and then increasing the flow speed of air in the cabinet body 1 so as to improve the air suction and exchange rate and further achieve the function of cooling;
s3, monitoring the smoke concentration of the protrusion of the cabinet body 1 in real time through the smoke sensor 5, when smoke is sensed, the micro electric extension rod 13 electrically connected with the smoke sensor immediately stretches up and down, and when the smoke sensor contracts downwards, the extrusion block 14 is driven to generate downward extrusion force on the upper movable handle in the extrusion handle 9, so that fire extinguishing substances in the dry powder fire extinguisher 8 are guided out to the inside of the cabinet body 1 from the position of the lengthened nozzle 11 to achieve the fire extinguishing effect;
s4, when the dry powder fire extinguisher 8 is used, the servo motor 15 electrically connected with the smoke sensor 5 and the micro electric extension rod 13 synchronously run, an output shaft of the servo motor drives the threaded rod 16 to rotate clockwise, then the lifting plate 6 assembled with the threaded rod 16 through thread embedding moves upwards along the outer surface of the threaded rod 16, then all objects placed above the lifting plate 6 synchronously move upwards, the lengthening nozzle 11 also moves upwards along the inside of the long groove 10 at the moment until the top of the extrusion handle 9 is attached to the top wall of the containing box 2, namely the output shaft of the servo motor 15 drives the threaded rod 16 to rotate anticlockwise;
s5, when the worker needs to clean the granular sundries accumulated on the object placing plate 4, the electric push rod 29 is started to extend outwards and generate forward pushing force on the object placing plate 4 until the front surface of the clamping block 26 is attached to the front wall of the L-shaped groove 23, namely, the electric push rod 29 stops running, then the electric telescopic rod 28 is started to contract downwards so as to generate downward pulling force on the object placing plate 4, and then the pulling force is transmitted to the positions of the two groups of embedded disks 25 so as to rotate for a set angle along the insides of the two groups of adjusting grooves 22, so that the object placing plate 4 is changed into an inclined state from a horizontal placing state.
The working principle is as follows: after a worker places the exchanger in a space formed by enclosing the N-shaped frame 18 and the movable baffle 20, the cabinet door 30 is closed, the heat dissipation fan 33 is opened, the flow speed of air in the cabinet body 1 is increased, the cooling effect is achieved, whether smoke is generated in the cabinet body 1 is monitored in real time through the smoke sensor 5, if the smoke is generated in the cabinet body 1, the miniature electric extension rod 13 electrically connected with the miniature electric extension rod immediately contracts downwards, the extrusion block 14 is driven to generate downward extrusion force on the upper movable handle in the extrusion handle 9, so that fire extinguishing substances in the dry powder fire extinguisher 8 are guided out to the inside of the cabinet body 1 from the position of the lengthening nozzle 11, meanwhile, the output shaft of the servo motor 15 drives the threaded rod 16 to rotate towards the clockwise direction, then the lifting plate 6 assembled with the threaded rod 16 through threaded embedding moves upwards along the outer surface of the threaded rod 16, and then all objects placed above the lifting plate 6 synchronously move upwards, and extension nozzle 11 is the same along the inside rebound of rectangular groove 10 this moment, until the top of extrusion handle 9 and the roof laminating of containing box 2, servo motor 15's output shaft drives threaded rod 16 and rotates towards anticlockwise promptly, so that height position is located in the adjustment from top to bottom to dry powder fire extinguisher 8, then the corresponding production of its inside dry powder of itself can rock, then can improve spun effect, and extension nozzle 11 is the same along rectangular groove 10 upper and lower activity, so that improve the scope that the dry powder sprayed, and then improve the effect of putting out a fire.
