[0049] Before introducing the technical solution of the present invention, it is necessary to explain the creation background of the invention of the present invention. It is common that with the increase in electricity demand and the expansion of the power grid, the application of high-voltage transmission line distribution boxes in extremely cold areas is becoming more and more widespread. However, the existing distribution boxes generally do not have external protective devices, which makes the distribution boxes susceptible to freezing under low temperature and severe weather conditions, resulting in unstable operation of the equipment in the distribution box and difficult maintenance. Therefore, the present invention aims to provide a distribution box with an anti-freezing function, which can effectively improve the anti-freezing ability of the distribution box in extremely cold areas.

[0050] See also Figures 1 to 7 According to an exemplary embodiment of the present invention, a distribution box with an anti-freezing function is provided, which includes a box body 11 and a box cover 12. A heating mechanism is provided inside the box body 11, and the box cover 12 is provided with a mounting seat 122 and an air outlet mechanism 2 rotatably mounted inside the mounting seat 122. The air outlet mechanism 2 can spray the high-temperature gas generated by the heating mechanism along the outer surface of the box cover 12 in a variety of forms. Specifically, the heating mechanism performs a heating operation, firstly raising the surface temperature of the box cover 12 so as to melt the bottom layer of snow on the surface of the box cover 12; the air outlet mechanism 2 draws the high-temperature gas generated by the heating mechanism out from the inside of the box body 11 and sprays it along the outer surface of the box cover 12 in a variety of forms, so as to produce a multi-dimensional melting effect on the snow on the box cover 12, accelerate the melting process of the snow as a whole, and avoid the formation of a thick snow layer.

[0051] See also Figure 3 to Figure 4 , the air outlet mechanism 2 is described from inside to outside and from bottom to top.

[0052] In some embodiments, the air outlet structure includes:

[0053] The motor 15 is disposed in the housing 11 , and is the power source for the air outlet mechanism 2 to perform the entire operation.

[0054] The cyclone tube includes a hollow cylinder 21 and a cyclone chamber 211 which is smaller at the top and larger at the bottom. The outside of the cyclone chamber 211 is connected to the motor 15 in a transmission manner. That is, under the drive of the motor 15, the cyclone tube can rotate and then lead the high-temperature gas out of the box body 11 through the cyclone chamber 211 which is smaller at the top and larger at the bottom at the bottom. It should be noted that the cyclone tube can be rotatably installed in the mounting seat 122.

[0055] The connecting sleeve 22 is fixedly connected to the top of the barrel 21 of the cyclone and is connected to the cyclone. It should be understood that the connecting sleeve 22 and the cyclone are separately arranged to facilitate the installation of the cyclone in the mounting seat 122. It should also be noted that the bottom of the connecting sleeve 22 and the top of the barrel 21 are both provided with flange structures and are fastened together by fasteners.

[0056] A plurality of first air pipes 23 have one end connected to the side of the connecting sleeve 22 . The first air pipes 23 are provided to guide the high-temperature gas entering the cyclone and the connecting sleeve 22 out along the plane of the box cover 12 .

[0057] The second air pipe 24 is annular in shape. The other end of any first air pipe 23 is connected to the second air pipe 24. A plurality of first jet holes are provided on the side of the second air pipe 24 facing away from the connecting sleeve 22. The second air pipe 24 is provided so that when the high-temperature gas is led out from the first air pipe 23, it enters the annular second air pipe 24 and is uniformly sprayed out in a circumferential direction from the first jet holes of the second air pipe 24.

[0058] The air outlet mechanism 2 further includes a cross fixing frame, which is fixedly connected to the top of the connecting sleeve 22 . The purpose of providing the cross fixing frame is to support the second air pipe 24 .

[0059] The above description provides a prototype of the air outlet structure, which is capable of drawing high-temperature gas out from the inner cavity of the box body 11 and spraying it on the surface of the box cover 12 .

[0060] Based on the above prototype, the first function of the air outlet structure will be optimized:

[0061] See also Figures 2 to 4 In some embodiments, the mounting seat 122 passes through the box cover 12 and is provided with an extension portion parallel to the outer surface of the box cover 12, and a side of the extension portion facing away from the box cover 12 is provided with an annular wave groove 1221;

[0062] The cross fixing frame includes a cross plate 221 and further includes:

[0063] A fixed plate 222, which is fixed to the bottom of each spoke of the cross plate 221 through two sets of blocking rods 2221;

[0064] A movable plate 223 is disposed between the spokes and the fixed plate 222. One end of the movable plate 223 is provided with a latch and inserted into the annular wave groove 1221, and the other end is used to clamp the second air pipe 24;

[0065] From the above description, it can be concluded that: when the cross plate 221 rotates, the baffle rod 2221 drives the movable plate 223 to rotate, and because the pin moves in the annular wave groove 1221, the movable plate 223 can drive the second air pipe 24 to move away from or closer to the connecting sleeve 22 synchronously, that is, the second air pipe 24 will additionally shake under the action of the movable plate 223 moving away from or close to the connecting sleeve 22, so that the high-temperature gas in the pipe generates additional kinetic energy so that it can be ejected from the first jet port to a farther distance. This is the first function optimization.

[0066] Next, based on the above-mentioned optimization of the first function, the second function optimization of the air outlet mechanism 2 is performed:

[0067] See also Figures 2 to 5 In some embodiments, a first clamping groove 2231 is provided at one end of the movable plate 223 away from the connecting sleeve 22, a spiral sleeve 3 is provided in the first clamping groove 2231, and the second air pipe 24 passes through the spiral sleeve 3; the movable plate 223 is also provided with a second clamping groove 2232 next to the clamping groove, a gear shaft 4 is rotatably provided in the second clamping groove 2232, a first push rod 41 which can be inserted into the spiral groove on the surface of the spiral sleeve 3 is provided at one end of the gear shaft 4, and a rack 2211 which can mesh with the gear shaft 4 is provided at the bottom of the spoke; wherein, when the movable plate 223 moves away from or approaches the connecting sleeve 22, the gear shaft 4 moves on the rack 2211 to rotate, and drives the first push rod 41 to continuously squeeze the spiral sleeve 3.

[0068] From the above description, it can be concluded that: the second air pipe 24 is externally sleeved with a plurality of spiral sleeves 3 and is clamped in the first clamping groove 2231 of the movable plate 223, so as to realize the supporting effect of the cross fixing frame on the second air pipe 24. When the movable plate 223 is away from or close to the connecting sleeve 22, the gear shaft 4 located in the second clamping groove 2232 cooperates with the rack 2211 to rotate, thereby driving the first push rod 41 of the rack 2211 to rotate and continuously squeeze the spiral groove on the surface of the spiral sleeve 3, that is, the spiral sleeve 3 and the second air pipe 24 are subjected to a tangential external force. Therefore, the second air pipe 24 will have a small tangential rotation on the basis of the additional shaking in the first function optimization, so that the high-temperature gas in the pipe has higher kinetic energy after the shaking and tangential rotation of the second air pipe 24, and can be sprayed to a larger area in a variable manner, ensuring that the top of the box cover 12 can receive sufficient heat in all directions, achieving uniform heating and thus more effectively melting the snow. This is the second function optimization.

[0069] Furthermore, on the basis that the air outlet mechanism 2 sprays high-temperature gas in a variety of ways, the air outlet structure of some embodiments also includes a snow sweeping device.

[0070] See also Figure 3 and Figure 6 , the snow removal device includes:

[0071] The limiting ring 5 is mounted on one end of each fixing plate 222 away from the connecting sleeve 22. It should be understood that this limiting ring not only serves as the installation basis of the components described below, but also can improve the stability of the overall structure of the cross fixing plate 222;

[0072] A sliding frame 51 is slidably mounted on the limiting ring 5. A snow sweeper 511 is disposed at one end of the sliding frame 51 away from the connecting sleeve 22. Both sides of each fixing plate 222 are provided with a sliding frame 51.

[0073] A second push rod 52, one end of which is hinged to the moving plate 223, and the other end of which is hinged to the sliding frame 51;

[0074] From the above description, it can be seen that when the moving plate 223 moves away from or approaches the connecting sleeve 22, the sliding frame 51 equipped with the snow-clearing plate 511 can slide along the limit ring 5 under the drive of the second push rod 52, and the snow-clearing plate 511 rotates synchronously to form a driving force for the snow on the top of the box cover 12, which can more quickly remove the snow from the top of the box cover 12, reduce the time the snow stays, or push away the snow that is melting or about to accumulate, avoid the formation of a thick snow layer, and reduce the risk of re-freezing. It should be noted that when the cross-fixing frame rotates, the snow-clearing plate 511 will rotate with the whole body. The purpose of setting this sliding frame 51 is to enable the snow-clearing plate 511 to additionally move back and forth to further strengthen the snow-clearing force.

[0075] Furthermore, in some embodiments, the air outlet mechanism 2 further includes an auxiliary air outlet device.

[0076] See also Figure 5 and Figure 7 The auxiliary air outlet device includes a support ring, which is fixed to the bottom of each fixing plate 222 and abuts against the outer surface of the box cover 12. The support ring includes two groups of single rings 61 distributed up and down, and a jet component 62 is sandwiched between the two groups of single rings 61. It should be understood that this support ring is not only an important component of the auxiliary air outlet device, but also plays a supporting role for the fixing plate 222 on the top of the box cover 12; wherein, a shunt pipe is arranged in the middle of the first air pipe 23, and the shunt pipe is connected to the upper single ring 61. The upper single ring 61 and the jet component 62 are both hollow structures. The first air pipe 23, the upper single ring 61 and the jet component 62 are connected, and a second jet hole is opened on the side of the jet component 62 facing away from the connecting sleeve 22.

[0077] From the above description, it can be seen that the auxiliary air outlet device is used to spray high-temperature gas to the space below the fixed plate 222, thereby expanding the overall spray range of the air outlet mechanism 2. Specifically, part of the high-temperature gas is drawn from the first air pipe 23 to the connected jet component 62 through the shunt pipe, and is sprayed outward from the second jet port of the jet component 62, thereby realizing the auxiliary air outlet function.

[0078] Preferably, the auxiliary air outlet device also has a local rotation function, please refer to Figure 1 Specifically, the auxiliary air outlet device also includes a rotating shaft with open ends, and the two ends of the rotating shaft are respectively inserted with a jet component 62 and an upper single ring 61 to connect the two, that is, not only the jet component 62 is connected with the upper single ring 61 and the jet component 62, but also the jet component 62 has a structural basis for rotating around the rotating shaft; at the same time, the auxiliary air outlet device also includes a plurality of first connecting rods 63 and a plurality of second connecting rods 64, the first connecting rod 63 is fixedly connected to one end of the jet component 62 close to the connecting sleeve 22, the second connecting rod 64 is arranged between two adjacent groups of first connecting rods 63 and is rotatably connected, and an elastic component 65 is provided between the second connecting rod 64 and the second air pipe 24 for connection, wherein the elastic component 65 is preferably a connecting spring.

[0079] From the above description, it can be concluded that when the movable plate 223 moves away from or approaches the connecting sleeve 22, the second air pipe 24 will expand or contract accordingly, and the second connecting rod 64 and the first connecting rod 63 will rotate through the elastic member 65, thereby driving the jet member 62 to rotate partially to have a wider spray range. At the same time, the high-temperature gas thrown outward has a strong impact force, which can penetrate a thicker snow layer, improve the contact effect between the hot air and the snow, accelerate the melting of the internal snow, and further reduce the accumulation of snow.

[0080] See also Figure 1 As a preferred technical solution, the box cover 12 is arranged at an angle. Such a design allows the melted snow water to naturally drain out of the box cover 12 and away from the box body 11; and a guide groove 121 is provided on the outer surface of the box cover 12 along the inclined direction. Such a design can reduce the contact area between the surface of the box cover 12 and the air outlet mechanism 2 to reduce the resistance of the overall rotation of the cross fixing frame, and the melted snow water will be discharged from the box cover 12 in the guide groove 121.

[0081] See also Figure 1 As a preferred technical solution, in order to make the distribution box of the present invention more intelligent, the distribution box includes a control unit 13 disposed on the side of the box body 11 and equipped with a temperature sensor 131. The heating mechanism and the air outlet mechanism 2 are both connected to the control unit 13 through signals to realize automatic adjustment, that is, the distribution box realizes the start and stop operation of the heating mechanism and the air outlet mechanism 2 through the preset programming in the control unit 13. Specifically, when it snows and snow accumulates on the top of the device, the control unit 13 is turned on to enable the temperature sensor 131 to monitor the internal and external temperatures of the distribution box. The monitored temperature data will then be transmitted to the control unit 13, and the control unit 13 automatically adjusts the heating mechanism for heating. At the same time, the control unit 13 starts the motor 15 to drive the air outlet mechanism 2 to start working. As a preferred technical solution, a solar photovoltaic panel 14 is disposed on the outer surface of the side of the box body 11 to provide energy for the heating mechanism and the air outlet mechanism 2.

[0082] In summary, the distribution box with anti-freezing function of the present invention has the following technical advantages: 1. The heating mechanism performs heating operation, firstly raising the surface temperature of the box cover 12 so as to melt the bottom layer of snow on the surface of the box cover 12; 2. The air outlet mechanism 2 draws the high-temperature gas generated by the heating mechanism out from the inside of the box body 11 and sprays it along the outer surface of the box cover 12 in a variety of forms, so as to produce a multi-dimensional melting effect on the snow on the box cover 12, accelerate the overall melting process of the snow, and avoid the formation of a thicker snow layer; 3. The present invention is committed to solving the problem of snow covering the box cover 12 of the distribution box, preventing an excessively thick snow layer from causing frost inside the distribution box and affecting the reliability and continuity of power supply, and also preventing the box cover 12 from being in a low temperature and high humidity environment for a long time and reducing its service life.
