Description

Technical Field

[0001] The invention relates to a constant temperature electric metering device for cold regions and a use method thereof, belonging to the field of electric energy meters. Background Art

[0002] In remote areas of the north, electric meter boxes in bungalow areas are generally installed on outdoor poles. However, the winter in the north is relatively cold, and the service life of the electric energy meter is greatly affected by being in a cold environment for a long time. It is necessary to increase its temperature to ensure the normal operation and service life of the electronic components inside the electric energy meter. The use of electricity and other energy to heat it requires workers to perform regular maintenance, and if the circuit is short-circuited, it is also very dangerous. Therefore, this constant temperature electric metering equipment for cold areas is designed. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the background technology and to provide a constant temperature electrical metering device for cold regions and a method of using the same.

[0004] The present invention achieves the above-mentioned purpose by adopting the following technical solutions:

[0005] A constant temperature electric metering device for cold regions comprises an electric energy meter, a casing, a back plate sealed casing, an air inlet pipe and a movable device; the electric energy meter and the casing are fixedly connected to the back plate; a through hole I is provided at the upper end of the back plate; the sealed casing is fixedly connected to the back plate and communicated with the through hole I, a through hole I is provided at the lower end of the sealed casing, and an air inlet pipe connected with the through hole I is provided at the lower end of the sealed casing; a movable device is provided inside the sealed casing.

[0006] A method for using a constant temperature electric metering device for cold regions, the method comprising the following steps:

[0007] Step 1: In winter, wind enters the sealed housing through the sliding pipe and pushes the movable device to move toward the housing;

[0008] Step 2: When the movable device moves, the transmission device drives the slide tube to move upward. When the slide tube moves to the inside of the inclined tube, the wind no longer enters the sealed shell. The movable device is pushed back to its original position under the elastic force of spring I, and the slide tube is driven to move downward. This cycle causes the movable plate II to rub against the shell repeatedly, generating heat.

[0009] Step 3: In summer, the air in the control tube expands due to heat, pushing the movable block toward the outer shell, driving the arc plate to move together, and connecting the L-shaped vent hole with through hole II, so that the air in the outer shell that expands due to heat enters the ventilation duct through the L-shaped vent hole, through hole II, and through hole III. Part of the air flows out through the notch, and the other part drives the outside air into the sealed outer shell, and then passes through the pores to enter the outer shell again, quickly reducing the temperature inside the outer shell.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention not only drives the movable plate II to move repeatedly through wind energy, but also utilizes its friction to generate heat energy to increase the temperature in the cavity between the electric energy meter and the outer shell, thereby achieving a good thermal insulation effect. At the same time, in summer, the device can also dissipate heat to prevent the internal components of the electric energy meter from being overheated and affecting their service life.

The hemispherical shells 56 drive the air inlet pipe 5 to change direction, so that the lower end of the sliding pipe 53 always faces the wind, ensuring that wind always enters the sealed housing 4, and preventing the movable device 7 from being unable to move after the wind direction is deviated by the building.

[0035] The outer circumferential surface of the control tube 8 is also fixedly connected with a ventilation device 10 which is in communication with the through hole III 81 .

[0036] The ventilation device 10 includes a ventilation duct 101 and an arc plate 102; the ventilation duct 101 is fixedly connected to the outer circumferential surface of the control tube 8 and is connected to the through hole III 81; the lower end of the sealed shell 4 is provided with a through hole IV 42 connected to the ventilation duct 101; the side of the ventilation duct 101 is provided with a notch 103; the lower end of the arc plate 102 is fixedly connected to the movable block 94, and the arc plate 102 seals the notch 103; the movable plate II 75 is provided with a plurality of air holes 76.

[0037] A method for using a constant temperature electric metering device for cold regions, the method comprising the following steps:

[0038] Step 1: In winter, wind enters the sealed housing 4 through the sliding pipe 53 and pushes the movable device 7 to move toward the housing 2;

[0039] Step 2: When the movable device 7 moves, the transmission device 6 drives the slide tube 53 to move upward. When the slide tube 53 moves to the inside of the inclined tube 52, the wind no longer enters the sealed housing 4. The elastic force of the spring I 73 pushes the movable device 7 back to its original position and drives the slide tube 53 to move downward. This cycle causes the movable plate II 75 to repeatedly rub against the housing 2 to generate heat.

[0040] Step three: In summer, the air in the control tube 8 expands due to heat, pushing the movable block 91 to move toward the outer shell 2, driving the arc plate 102 to move together, and connecting the L-shaped vent hole 95 with the through hole II 92, so that the air in the outer shell 2 that expands due to heat enters the ventilation duct 101 through the L-shaped vent hole 95, through hole II 92, and through hole III 81, a part of which flows out through the notch 103, and the other part drives the outside air into the sealed outer shell 4, and then passes through the air hole 76 to enter the outer shell 2 again, quickly reducing the temperature inside the outer shell 2.

[0041] The working principle of the present invention is: when using the device for installation, the sealing housing 4 is installed on the windward side of the local area;

[0042] In winter, wind enters the sealed housing 4 through the sliding pipe 53 and the inclined pipe 52, and the wind force pushes the movable plate I 71 on the movable device 7 to move toward the housing 2. The movable plate I 71 drives the connecting rod 72 and the movable plate II 75 to move together and compress the spring I 73. The contact position between the movable plate II 75 and the housing 2 is provided with a friction pad for generating heat after friction.

[0043] At the same time, when the movable device 7 moves, the movable plate I 71 drives the transmission rod 61 to move through the V-shaped rod 64 on the transmission device 6, and the transmission rod 61 drives the slide tube 53 to move upward along the inclined tube 52 through the round rod. When the slide tube 53 moves to the inside of the inclined tube 52, since the lower end of the inclined tube 52 is parallel to the horizontal plane, the air intake is reduced. At this time, the elastic force of the spring I 73 is greater than the wind force. Under the action of the elastic force of the spring I 73, the movable device 7 is pushed back to its original position and the slide tube 53 is driven to move downward. In this cycle, the movable plate II 75 repeatedly rubs against the outer shell 2 during the reciprocating movement to generate heat, thereby increasing the air temperature inside the outer shell 2, so that it has a heat insulation effect;

[0044] When the wind direction is affected by the local buildings and changes, the hemispherical shell 56 is blown, so that the hemispherical shell 56 rotates, and then drives the inclined tube 52 to rotate around the connecting tube 51, and at the same time the inclined tube 52 drives the sliding tube 53 to rotate. When the windward end of the lower end of the sliding tube 53 rotates to the windward side, the hemispherical shell 56 rotates to the rear end of the inclined tube 52, and after no longer being subjected to force, the inclined tube 52 stops rotating, so that the lower end of the sliding tube 53 always has wind entering the sealed housing 4, ensuring that the movable plate II 75 can move under force, and continuously generates heat through friction;

[0045] When the gas temperatures inside the control tube 8 and the shell 2 are the same, the gas pressure inside the control tube 8 is greater than the gas pressure inside the shell 2;

[0046] In summer, the air in the control tube 8 expands due to heat, and the pressure increases. When it is greater than the elastic force of the spring II 96, the movable block 91 is pushed to move toward the housing 2, and the movable block 91 drives the arc plate 102 to move together. After the movable block 91 moves to the right, the L-shaped vent hole 95 is connected with the through hole II 92, so that the air in the housing 2 expands due to heat enters the ventilation duct 101 through the L-shaped vent hole 95, the through hole II 92, and the through hole III 81. Since the arc plate 102 moves with the movable block 91, the notch 103 is exposed. Part of the gas flowing into the ventilation duct 101 flows out through the notch 103, and the other part moves upward along the ventilation duct 101, so that the flow velocity in the ventilation duct 101 increases and the air pressure decreases. The outside gas enters the ventilation duct 101 through the notch 103, and moves upward with the hot air flow into the sealed shell 4, and then passes through the air hole 76 to enter the shell 2 again, so that the outside gas with lower temperature enters the shell 2, quickly reduces the temperature in the shell 2, and prevents the temperature of the electric energy meter 1 from being too high in summer.

[0047] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention.
