The detailed implementation mode is ten: as shown in fig. 1 to 10, the present embodiment describes a constant temperature method for an electric energy meter constant temperature device in a severe cold area, the constant temperature method including the steps of:
the method comprises the following steps: the hydraulic cylinder 27 is started, the hydraulic cylinder 27 pushes the friction device II 28 to move, and heat is generated;
step two: the friction device II 28 pushes the friction device I25 and the friction device III 26 to move, heat is generated, the square block 21 is exchanged with air inside the electric energy meter 1, sufficient flowing of hot air is guaranteed, and meanwhile the electric energy meter 1 is driven to move up and down;
step three: cleaning device 22 moves along with electric energy meter 1 reciprocates and moves near the outer wall of fixing base 2, clears up the drop of water on the outer wall of fixing base 2.
The working principle of the invention is as follows: when the device is used, the hydraulic cylinder 27 is started, the hydraulic cylinder 27 drives the friction device II 28 to reciprocate in the slide way II 218, when the friction device II 28 moves towards the direction of the hydraulic cylinder 27 in the state shown in figure 3, after the air in the slide way II 218 passes through the through hole I219 by the friction device II 28, part of the air enters the electric energy meter 1 through the communication hole 12, the other part of the air enters the space between the electric energy meter 1 and the base 2111, after the friction device II 28 passes through the through hole I219 (namely, the right side of the through hole I219 shown in figure 3) and continues to move under the driving of the hydraulic cylinder 27, the air between the friction device II 28 and the hydraulic cylinder 27 is compressed, the air pressure is increased, and meanwhile, as the cushion block 212 is fixedly connected in the slide way I213, therefore, the width of the chute I213 is smaller than the width of the chute II 218 and the chute III 2113, after the air pressure is increased, the air pressure is slowly released through the chute I213, the rubber baffle 264 in the rubber tube 261 can only rotate towards the inside of the rubber tube 261, and the friction device III 26 in the advancing direction of the friction device II 28 is pushed to move towards the direction away from the hydraulic cylinder 27, during the movement of the friction device III 26, the friction device III 26 rubs with the inner shell 214 to generate heat and enters the inside of the rubber tube 261 through the hole 263, the air in the rubber tube 261 is heated until the friction device II 28 moves to be nearest to the hydraulic cylinder 27, the friction device III 26 also moves to be farthest from the hydraulic cylinder 27, and the rotating baffle 264 is propped open through the cylinder 215, so that the hot air in the friction device II 28 flows into the chute 2113;
as shown in fig. 3, when the friction device ii 28 moves to the left of the through hole i 219, the space on the left side of the friction device ii 28 increases, the air pressure decreases, and thus the other friction device iii 26 is driven to move toward the chute ii 218 until the friction device ii 28 moves to pass through the through hole i 219, the friction device iii 26 contacts the cylinder 215 near the through hole i 219, and releases the heat in the rubber cylinder 261 into the chute ii 218 in the above manner, when the friction device ii 28 moves to the right of the through hole i 219, air is drawn into the chute ii 218 through the through hole i 219, so that the air on the left side of the friction device i 25 enters the electric energy meter 1 through the through hole ii 2112, and then enters the chute ii 218 through the through hole i 219, so that the air pressure on the left side of the friction device i 25 decreases, and when the friction device ii 28 moves to the right, the friction device iii 26 on the right of fig. 3 moves upward, pushes the air on the right side of the friction device i 25 to increase, and the friction device i 25 moves to the left, and further passes through the through hole ii 2112; when the hydraulic cylinder 27 extends, the reverse movement is performed according to the operation, so that the air flow in the square block 21 and the electric energy meter 1 can repeatedly and circularly move in the inside, and further, the heat is prevented from being accumulated at a certain position and the temperature in the electric energy meter 1 can be ensured to be constant; the friction device I25 and the friction device II 28 respectively rub the inner walls of the sliding groove II 218 and the sliding groove III 2113 in the movement process to generate heat, and when the friction device I25 and the friction device II 28 are subjected to pressure of air pressure, the two rubber plates 251 are close to each other, so that the pressure of the rubber column 257 and the inner walls of the sliding groove II 218 and the sliding groove III 2113 is increased, the friction force is further increased, and the generated heat is increased;
when the friction device ii 28 moves, air in the chute ii 218 is pushed into a gap between the electric energy meter 1 and the base 2111 through the through hole i 219, because the width of the through hole i 219 is greater than the width of the through hole ii 2112, the air entering amount into the gap between the electric energy meter 1 and the base 2111 is greater than the air discharging amount, so that the air pressure in the gap between the electric energy meter 1 and the base 2111 pushes the electric energy meter 1 to move to the right side shown in fig. 1, when the electric energy meter 1 moves, the spring iii 16 is compressed and the transmission rod 23 is driven to move, the transmission rod 23 drives the transmission cylinder 223 to rotate, and further the connection rod 222 is driven to rotate, the connection rod 222 drives the L-shaped rod 221 to scrape off water droplets on the square block 21 and the base 2111 (the water droplets are water droplets condensed on the outer surfaces of the square block 21 and the base 2111 due to the difference between the internal temperature of the device and the external temperature), ice is prevented from being frozen on the surfaces, heat in the device is sucked, and the temperature in the electric energy meter 1 is further influenced by the constancy of the temperature.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
