The second feeding hole 38 is formed in the discharging box 22, a second feeding block 39 is arranged at the second feeding hole 38, when fire extinguishing powder needs to be added into the discharging box 22, a worker takes out the second feeding block 39 from the second feeding hole 38, so that the fire extinguishing powder is conveniently added into the carrying box 15 through the second feeding hole 38, the purpose of adding the fire extinguishing powder into the discharging box 22 is achieved, the second feeding block 39 is installed at the second feeding hole 38, and the second feeding hole 38 is plugged through the second feeding block 39.
Working principle: when the fire-extinguishing powder needs to be added into the carrying box 15, a worker takes out the first feeding block 37 from the inside of the first feeding hole 36, so that the fire-extinguishing powder is conveniently added into the carrying box 15 through the first feeding hole 36, the aim of adding the fire-extinguishing powder into the carrying box 15 is fulfilled, the first feeding block 37 is installed at the first feeding hole 36, and the first feeding hole 36 is plugged through the first feeding block 37.
When the fire-extinguishing powder needs to be added into the discharging box 22, the second feeding block 39 is taken out from the second feeding hole 38 by a worker, so that the fire-extinguishing powder is conveniently added into the carrying box 15 through the second feeding hole 38, the aim of adding the fire-extinguishing powder into the discharging box 22 is fulfilled, the second feeding block 39 is installed at the second feeding hole 38, and the second feeding hole 38 is plugged through the second feeding block 39.
When the fire-extinguishing powder needs to be replenished inside the charging box 3, a worker pulls the push-pull plate 21 manually, the space inside the charging area 18 is enlarged in the process of moving the push-pull plate 21, and at this time, the spring 20 is in a compressed state, and the fire-extinguishing powder inside the charging box 15 flows to the inside of the charging area 18 through the discharge pipe 19 due to the placement of the fire-extinguishing powder inside the charging box 15, thereby realizing replenishment of the fire-extinguishing powder inside the charging area 18.
Since the motor body 1 will generate high temperature in the use process, since the inside of the second accommodation area 10 is filled with the coolant, the liquid pump 29 works to realize that the coolant inside the second accommodation area 10 flows to the inside of the heat dissipation shell 12 through the liquid discharge pipe 30, and since the heat dissipation shell 12 is positioned inside the sealed shell 2, the heat near the motor body 1 transfers the radiation to the inside of the heat dissipation shell 12, the purpose of absorbing heat and reducing temperature is achieved through the coolant inside the heat dissipation shell 12, and then the coolant inside the heat dissipation shell 12 flows to the first accommodation area 9, and the coolant flows back to the second accommodation area 10 through the connecting pipe 11, so that the coolant is convenient to recycle.
Because the motor body 1 will produce high temperature in the use, the heat that consequently is convenient for motor body 1 radiation is conducted to the inside of heat dissipation shell 12, realizes the cooling effect through the coolant liquid.
Since the material of the connection pipe 11 is a heat conductive material and the connection pipe 11 is located inside the vent hole 28, the inside of the vent hole 28 can realize air flow due to the higher temperature of the cooling liquid passing through the inside of the heat dissipation case 12, thereby facilitating heat dissipation of the cooling liquid inside the connection pipe 11.
The motor body 1 is used in inflammable and explosive places, when the burning explosion phenomenon appears in the place of use of motor body 1, the inside temperature of place of use will rise, a high Wen Jiangdi film 6 melts, thereby make discharge gate 5 be in open condition, the inside fire extinguishing powder of charging box 3 flows to blowing clearance 4 through discharge gate 5, realize protecting motor body 1 through the fire extinguishing powder, prevent that place inside from appearing burning explosion phenomenon causes the damage to motor body 1, simultaneously because this application has set up two at least charging boxes 3, and be provided with blowing clearance 4 between the adjacent charging box 3, therefore the inside fire extinguishing powder that flows out of charging box 3 is located the inside of blowing clearance 4, thereby prevent that fire extinguishing powder breaks away from seal housing 2 and influence the guard action to motor body 1.
Since the fire extinguishing powder in the charging area 18 is reduced, and the baffle 16 is moved by the elastic reset action of the spring 20, the moving rod 26 is moved in the moving process of the baffle 16, the poking rod 27 is moved in the moving process of the moving rod 26, and the second film 25 is poked in the moving process of the poking rod 27, so that the fire extinguishing powder in the cavity 23 is discharged to the surface of the motor body 1 through the discharge hole 24, and the motor body 1 is protected by the fire extinguishing powder.
When the inside of the hermetic shell 2 is brought into the fire extinguishing powder, and when the fire has been extinguished and there is no danger in the use situation, it is necessary to clean the fire extinguishing powder inside the hermetic shell 2, the worker manually rotates the fixing bolt 33, when the fixing bolt 33 is disengaged from the hermetic shell 2 and the pulling plate 32, the worker manually pulls the pulling plate 32, the liquid blocking plate 14 is moved during the movement of the pulling plate 32, so that the liquid outlet hole 13 is opened, so that the cooling liquid inside the heat dissipation shell 12 is caused to flow out through the liquid outlet hole 13, the fire extinguishing powder inside the hermetic shell 2 is flushed by the cooling liquid, so that the fire extinguishing powder inside the hermetic shell 2 is cleaned, and since the inside of the hermetic shell 2 is communicated with the first accommodating area 9, the fire extinguishing powder and the cooling liquid flow to the first accommodating area 9 after the flushing of the inside of the hermetic shell 2, and then flow to the second accommodating area 10 through the connecting pipe 11, the worker takes the liquid blocking block 41 from the inside of the discharge hole 40, so that the fire extinguishing powder inside the second accommodating area 10 and the cleaning liquid are caused to be discharged through the discharge hole 40.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
