Description

Technical Field

[0001] The invention relates to the technical field of electromechanical devices, and in particular to an electric energy metering box with a fireproof and heat dissipation structure. Background Art

[0002] The electric energy meter box is used for the installation and protection of electric meters. The electric energy meter box is divided into indoor and outdoor types according to its use, and is divided into direct current and current transformer according to current, and is divided into low voltage and high voltage according to voltage. Since the electric energy meter box is installed with components for measuring electric energy, such as electric energy meters and current transformers, these components will generate heat when working for a long time. If the heat cannot be dissipated in time, it will cause the temperature inside the box to rise, affecting the stability and service life of the components. In order to ensure the basic functions of electrical components, multiple heat dissipation holes are usually set on the side of the electric energy meter box to ensure air flow inside and outside the box, help keep the internal temperature of the electric energy meter box within a safe range, avoid the temperature of the electric energy meter being too high during operation, resulting in a decrease in measurement accuracy, and prevent safety accidents such as electrical fires caused by overheating.

[0003] However, the heat dissipation structure opened on the outside of the box has a fixed size and angle, and the heat dissipation effect is poor. Dust, wind and rain in the external environment can easily enter it. The outdoor environment is changeable. In heavy rain, the heat dissipation structure suitable for conventional weather cannot perform rain protection operations well. Rainwater will flow into the device along the heat dissipation holes, causing damage to electrical components and causing safety accidents such as electrical fires. In view of this, the present invention provides an electric energy metering box with a fireproof heat dissipation structure. Summary of the invention

[0021] Beneficial Effects

[0022] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0023] The present invention is provided with a baffle plate 1. When the rainwater received by the rain sensing part reaches a threshold value, the connecting rod extends to drive the rotating plate to rotate in the direction of the outer groove, the rotating plate presses the long plate downward, and the long plate slides inside the movable groove. The size of the positioning groove 1 is larger than that of the limiting block 1. The lateral size generated by the arc rotation of the limiting block 1 around the rotating shaft 1 can be compensated by sliding on the inner wall of the positioning groove 1, and the longitudinal displacement causes the long plate to drive the positioning groove 1 to move downward synchronously, and the positioning groove 1 drives the limiting block 1 rotatably connected thereto to move downward. The limiting block 1 is forced downward to drive the baffle plate 1 to rotate around the rotating shaft 1, thereby turning the baffle plate 1 in a vertical state outward to an inclined state, thereby shielding the rainwater above.

[0024] The present invention is provided with a heat dissipation hole 2 and a heat dissipation hole 1, the two are aligned in height, and the size of the heat dissipation hole 1 is smaller than that of the heat dissipation hole 2, forming a channel that is small outside and large inside. External dust passes through the small-sized heat dissipation hole 1 for filtering, and some of it may fall into the channel and be collected by the dust accumulation plate. The hot air inside the box is discharged to the outside of the box through the large-sized heat dissipation hole 2. The flow rate increases when passing through the small-diameter heat dissipation hole 1, which will blow off the accumulated dust to a certain extent. When the baffle plate 1 is tilted to block rain, the heat dissipation hole 1 in the lower half of the baffle plate is washed by rainwater at a position away from the frame, and dust is cleaned while blocking rain. The dust on the dust accumulation plate is also washed clean by the dual effects of gravity and rainwater.

[0025] The present invention is provided with a linkage member and a second baffle plate. When the second baffle plate rotates clockwise toward the inner side of the box body, the second baffle plate is changed from a vertical state to an inclined state in the box body. At this time, the second baffle plate and the first baffle plate are parallel to each other. The first baffle plate performs preliminary shielding of rainwater. If there are some splashing water droplets, they will be shielded for a second time by the inclined second baffle plate, thereby improving the rain shielding effect of the device.

[0026] The present invention is provided with a side panel, and a rain shield film is provided on the inner side of the side panel. In the initial state, the rain shield film is in a folded state. A side of the rain shield film away from the box body is rotatably connected with a baffle plate. The size between the baffle plates is smaller than the size of baffle plate 1. When baffle plate 1 rotates outside the box body, the outer surface of baffle plate 1 contacts the baffle plate. In the subsequent rotation process, baffle plate 1 drives the baffle plate to rotate synchronously. The baffle plate rotates to unfold the folded rain shield film, thereby shielding one side of the inclined baffle plate to prevent rainwater from penetrating into the box body from the side.

[0027] The present invention is provided with a rain sensing part, which can be set as a sensor element for sensing moisture in the environment, or as a rain storage box for storing rainwater. The preferred scheme in the present invention is the rain storage box, and the rain receiving port of the rain storage box is much larger than the water outlet. When the rainfall is large, the rainwater received in the rain storage box will gradually increase and thus contact with one end of the rotating plate. When the rainfall decreases, the rainwater stored in the rain storage box will be less than that in the period of large rainfall. Although it is still in contact with the rotating plate, the rotation angle of the rotating plate becomes smaller, thereby realizing dynamic regulation. At the same time, after the rain stops, the rain storage box can be restored to a water-free state in a short time without the need for staff to dump it, thereby reducing the workload of staff and realizing self-regulation of the device.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention will be further described below in conjunction with the embodiments. Example

[0038] See also Figure 1-Figure 6 The present invention provides a technical solution for an electric energy metering box with a fireproof heat dissipation structure: the device includes a box body 1 with multiple electrical components installed, and a heat dissipation part 3 for heat dissipation is arranged on the side of the box body 1.

The heat dissipation hole 321 is set to a smaller aperture, which can well filter dust and impurities in the external environment. The dust and impurities accumulate on the inner wall of the heat dissipation hole 321, and the positioning groove 354 is fixedly set in the long plate 351 located in the space of the outer groove 311, and the long plate 351 is slidably connected to the inner wall of the movable groove 313, and the top of the long plate 351 is rotatably connected with a rotating plate 317, the rotating plate 317 is rotatably connected with the top groove 316 opened at the top of the heat dissipation hole 321, and a rain sensing part 2 is arranged on the top of the rotating plate 317. The rain sensing part 2 can be set as a sensor element for sensing moisture in the environment, and can also be set as a rain storage box for storing rainwater. The preferred scheme in the present invention is a rain storage box, and the rain receiving port of the rain storage box is much larger than the water outlet. When the rainfall is large, the rainwater received in the rain storage box will gradually increase and thus contact with one end of the rotating plate 317. When the rainfall decreases, the rainwater received in the rain storage box will be less than that in the period of large rainfall. Although it is still in contact with the rotating plate 317, the rotation angle of the rotating plate 317 becomes smaller, thereby realizing dynamic regulation. At the same time, after the rain stops, the rain storage box can be restored to a water-free state in a short time without the need for the staff to dump it, thereby reducing the workload of the staff and realizing self-regulation of the device.

[0040] A connecting rod is provided at the bottom end of the rain sensing part 2, and a telescopic spring is sleeved on the outside of the connecting rod. The bottom end of the connecting rod is rotatably connected to the rotating plate 317 near the outer groove 311. When the rain received by the rain sensing part 2 reaches the threshold, the connecting rod extends to drive the rotating plate 317 to rotate toward the outer groove 311. The rotating plate 317 presses the long plate 351 downward, and the long plate 351 slides inside the movable groove 313. The size of the positioning groove 1 354 is larger than that of the limit block 1 322. The limit block 1 322 is centered on the rotating shaft 1 323. The lateral dimension generated by the arc rotation of the center can be compensated by sliding on the inner wall of the positioning groove 354, and the longitudinal displacement will cause the long plate 351 to drive the positioning groove 354 to move downward synchronously, and the positioning groove 354 drives the limit block 322 rotatably connected thereto to move downward, and the limit block 322 is forced downward to drive the baffle plate 32 to rotate around the rotating shaft 323, thereby flipping the vertical baffle plate 32 outward to an inclined state, thereby blocking the rain from above.

[0041] refer to Figure 2 and Figure 3The frame 31 is fixedly connected to a side panel 34 on the outside, and a rain shield film 341 is arranged on the inside of the side panel 34. In the initial state, the rain shield film 341 is in a folded state. The side of the rain shield film 341 away from the box body 1 is rotatably connected to a baffle 342. The size between the baffles 342 is smaller than the size of the baffle 32. When the baffle 32 rotates outside the box body 1, the outer surface of the baffle 32 contacts the baffle 342. In the subsequent rotation process, the baffle 32 drives the baffle 342 to rotate synchronously. The baffle 342 rotates to unfold the folded rain shield film 341, thereby shielding the inclined side of the baffle 32 to prevent rainwater from seeping into the box body 1 from the side.

[0042] refer to Figure 2 , Figure 4 and Figure 6 In the initial state, the outer groove 311 and the inner groove 312 are in a parallel state, the baffle 1 32 inside the outer groove 311 and the baffle 2 33 inside the inner groove 312 are also in a parallel state, the double-layer structure of the baffle 1 32 and the baffle 2 33 has a good fire prevention effect, a heat dissipation hole 1 321 is opened at the lower half of the baffle 1 32, a dust accumulation plate is arranged on the side of the bottom of the heat dissipation hole 1 321 close to the baffle 2 33, and the other end of the dust accumulation plate is in contact with the bottom of the baffle 2 33, and a heat dissipation hole 2 331 is opened at the lower half of the baffle 2 33, the heat dissipation hole 2 331 is flush with the heat dissipation hole 1 321, and the size of the heat dissipation hole 1 321 is smaller than the heat dissipation hole 2 331 The size forms a channel which is small on the outside and large on the inside. The external dust is filtered by the small-sized heat dissipation hole 321, and some of it may fall into it and be collected by the dust accumulation plate. The hot air inside the box body 1 is discharged to the outside of the box body 1 through the large-sized heat dissipation hole 2 331. The flow rate increases when passing through the small-aperture heat dissipation hole 321, which will blow off the accumulated dust to a certain extent. When the baffle 32 is tilted to block the rain, the heat dissipation hole 321 in the lower half of the baffle 32 is washed by rainwater at a position away from the frame 31, and the dust is cleaned while blocking the rain. The dust on the dust accumulation plate is also washed clean by the dual effects of gravity and rainwater.

[0043] refer to Figure 3 , Figure 4 and Figure 5The linkage member 35 also includes a positioning block 352 fixed to the side of the long plate 351. A round block fixedly connected to one end of the connecting plate 353 is arranged inside the positioning block 352. The positioning block 352 moves vertically with the long plate 351 and drives the connecting plate 353 to rotate on the inner wall of the frame 31 through the round block. The inner size of the positioning block 352 is larger than the round block. The lateral size of the connecting plate 353 makes the round block slide inside the positioning block 352. When the connecting plate 353 rotates, it drives the long plate movably connected on the other side. 351 moves upward, and the long plate 351 is located in the space of the inner groove 312. When the long plate 351 moves upward, it drives the positioning groove 355 to move upward. The positioning groove 355 moves upward and drives the limit block 332 to move upward. The limit block 332 moves upward and drives the baffle plate 33 to rotate around the rotating shaft 333. The rotating shaft 333 is rotationally connected with the limit groove 315. The baffle plate 33 rotates clockwise toward the inside of the box body 1, and changes the baffle plate 33 from a vertical state to an inclined state in the box body 1.

The barrier 36 is located inside the baffle 2 33. The barrier 36 includes a magnetic plate 1 361 magnetically connected to the magnetic plate 2 37. The size of the magnetic plate 1 361 is larger than the size of the fixed groove 334. A rubber plate 335 is fixedly connected to the top of the baffle 2 33. When the magnetic plate 1 361 falls away from the magnetic field space of the magnetic plate 2 37, the rubber plate 335 can protect the bottom end of the magnetic plate 1 361 to avoid damage caused by the impact of the fall. A fixed plate 362 is fixedly connected to the bottom end of the fixed plate 362. The fixed plate 362 is slidably connected to the fixed groove 334 opened in the baffle 2 33. A heat dissipation hole 363 with the same size as the heat dissipation hole 2 331 is opened on the lower half of the fixed plate 362. When the magnetic plate 1 361 is affected by the When the magnetic plate 2 37 is attracted by magnetic action, that is, when the baffle plate 2 33 is in a vertical state, the heat dissipation hole 2 331 is flush with the heat dissipation hole 363 and remains in a through state. When the baffle plate 2 33 rotates and tilts toward the inner side of the box body 1, the magnetic plate 1 361 moves away from the magnetic field space of the magnetic plate 2 37. The magnetic plate 1 361 and the fixed plate 362 slide toward the inner side of the fixed groove 334 under the action of gravity. The fixed plate 362 moves a distance of the heat dissipation hole 363 to close the heat dissipation hole 2 331. At this time, the baffle plate 2 33 is a rectangular plate without holes, and the side edges of the baffle plate 2 33 are slidably sealed with the inner wall of the box body 1 and the inner wall of the frame 31. At this time, the baffle plate 2 33 and the baffle plate 1 32 are parallel to each other. The baffle plate 1 32 initially blocks the rain. If there are some splashing water droplets, they will be blocked for the second time by the inclined baffle plate 2 33, thereby improving the rain shielding effect of the device.
