Description

Technical Field

[0001] The utility model relates to the technical field of electric energy metering boxes, in particular to a safe electric energy metering box. Background Art

[0002] The meter box is a collection of metering instruments and auxiliary equipment necessary for measuring electric energy, including electric energy meters, voltage and current transformers for measurement and their secondary circuits, electric energy metering panels, cabinets, boxes, etc. In order to facilitate electric energy statistics, multiple groups of electric energy meters are generally set inside the meter box for counting to achieve the effect of unified measurement. However, the existing electric energy meter boxes still have certain usage defects during use, such as:

[0003] The utility model announcement number CN219087651U discloses a heat dissipation device for an electric energy meter box. By setting a heat dissipation fan, the temperature in the electric energy meter box body can be dissipated to avoid the temperature rise in the electric energy meter box body affecting the internal electronic components. By setting a storage mechanism, the user can store the insect repellent under the action of the storage mechanism. Under the action of the heat dissipation fan, the smell of the medicine stored in the storage mechanism is transported, so that the insect repellent enters the electric energy meter box body under the action of the heat dissipation fan, thereby avoiding insects from entering the electric energy meter box body and affecting the electric energy meter box body, so as to facilitate the user to dissipate the temperature in the electric energy meter box body and avoid insects from entering the electric energy meter box body and affecting the electric energy meter box body.

[0004] In the above document, during the operation of the internal structure of the meter box, the heat dissipation fan needs to discharge the heat inside the body through the buckle grooves. In the cold winter, the heat generated by the internal structure of the meter box body can be directly lost through the body without the need for a fan to transfer it. During this process, the buckle grooves are always in an open state, which can easily cause dust to enter the interior of the body through the buckle grooves. Dust adhering to the upper end of the internal structure of the meter box will affect the heat dissipation of the structure, which can easily lead to unstable heat dissipation of the meter box and affect the safety of the use of the meter box.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original metering box structure. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In a specific embodiment, Figure 1-Figure 2 As shown;

[0033] A box body 1 and a protective plate 2 fixedly mounted on the upper end of the box body 1;

[0034] Two groups of air inlets 3 are provided at the lower end of the box body 1, and a filter screen 23 is fixedly installed inside the air inlet 3. A fan assembly 4 is fixedly installed inside the upper end of the box body 1, and an air outlet 5 is provided at the upper end of the box body 1, and the air outlet 5 is located at the upper end of the fan assembly 4. At the same time, a temperature sensor 22 is fixedly installed at the upper end of the box body 1.

[0035] When using the safety-type electricity meter box, the electronic components inside the box 1 will generate heat when working. In hot weather, heat is easily accumulated inside the box 1. In order to ensure the stable operation of the electronic components inside the box 1, the heat inside the box 1 needs to be discharged to the outside. During this process, the temperature sensor 22 will preferentially receive the information that there is too much heat inside the box 1. Then the fan assembly 4 will work and allow the air outside the box 1 to enter through the two sets of air inlets 3, and then exit through the air outlet 5 at the upper end of the box 1. During this process, the heat inside the box 1 can be discharged, thereby ensuring the stable operation of the electricity meter box.

[0036] In one specific embodiment, Figure 1-Figure 6 As shown;

[0037] An opening and closing structure is provided inside the box 1, and the opening and closing structure can achieve the effect of effective heat dissipation of the box 1;

[0038] The opening and closing structure is provided with a left baffle 6 and a right baffle 7 inside. The left baffle 6 and the right baffle 7 are slidably mounted on the upper end of the box body 1, and the ends of the left baffle 6 and the right baffle 7 close to each other are located inside the air outlet 5, and an electric push rod 8 is fixedly mounted on the lower end of the left baffle 6, and the electric push rod 8 is fixedly connected to the box body 1;

[0039] A mounting block 9 is fixedly mounted on the outer side of the left baffle 6, and a first tooth plate 10 is fixedly mounted on the side of the mounting block 9 away from the left baffle 6, a second tooth plate 11 is fixedly mounted on the outer side of the right baffle 7, and two sets of first gears 12 are rotatably mounted on the upper end of the box body 1;

[0040] The first tooth plate 10 and the second tooth plate 11 are both meshed and connected with the first gear 12, the second tooth plate 11 passes through the mounting block 9, and a traction rope 13 is fixedly installed at one end of the first tooth plate 10 and the second tooth plate 11 away from each other;

[0041] A sealing plate 14 is provided inside the opening and closing structure, and the sealing plate 14 is slidably installed inside the box body 1, and the sealing plate 14 is located at the upper end of the air inlet 3, a limiting plate 15 is fixedly installed on the outer side of the sealing plate 14, and a ball 16 is nested inside the limiting plate 15, and the limiting plate 15 is slidably connected to the box body 1.

[0042] In the process of using the safety type electric energy metering box, the electric push rod 8 will work before the fan assembly 4 works, and the electric push rod 8 will shrink and make the left baffle 6 away from the air outlet 5. During the movement of the left baffle 6, the first tooth plate 10 will be driven to move through the mounting block 9, and the first tooth plate 10 will drive the second tooth plate 11 to move through the first gear 12. At this time, the first tooth plate 10 and the second tooth plate 11 will move synchronously, and the right baffle 7 will also be away from the air outlet 5. At this time, the air outlet 5 will be in an open state, and the first tooth plate 10 and the second tooth plate 11 will be pulled by the traction rope 13. When the limit plate 15 moves and the third tooth plate 17 moves, the sealing plate 14 will move upward inside the air inlet 3. At this time, the air inlet 3 is also in an open state, which is convenient for ventilation inside the box 1, and the filter screen 23 inside the air inlet 3 will filter the air to prevent dust in the air from entering the inside of the box 1. By closing the air inlet 3 and the air outlet 5, dust can be effectively prevented from entering the inside of the box 1. At the same time, in cold winter conditions, the power loss of the fan assembly 4 itself and the heat generated can be reduced to ensure that the metering box can effectively dissipate heat.

[0043] Based on the above embodiments, Figure 1-Figure 2 and Figure 6-Figure 8 As shown;

[0044] A cleaning structure is provided inside the box 1, and the cleaning structure can achieve the effect of stable ventilation and heat dissipation inside the box 1;

[0047] During the upward movement of the sealing plate 14, the sealing plate 14 will drive the third tooth plate 17 to move upward, and the upward movement of the third tooth plate 17 will cause the fourth tooth plate 20 to move downward through the second gear 18, and during the downward movement of the fourth tooth plate 20, the cleaning brush 21 will move downward and clean the filter 23 with the cleaning brush 21, thereby removing dust adhered to the outside of the filter 23 to ensure the ventilation effect of the filter 23, and after the sealing plate 14 and the air inlet 3 are closed, the cleaning brush 21 will move upward and clean the filter 23 again, thereby ensuring the ventilation effect of the box body 1, further improving the working stability of the electric energy metering box, and increasing the overall practicality.
