Description

Technical Field

[0001] The present invention relates to the technical field of power transmission and transformation equipment, and in particular to a high-altitude power transmission and transformation equipment with a variable weather-resistant protection mechanism. Background Art

[0002] As the altitude increases, the air pressure decreases and the air becomes thinner, which leads to a weakening of the environment's insulation, heat conduction and convection heat dissipation capabilities. When the power transmission and transformation equipment is in operation, it generates a lot of heat. If it relies solely on environmental heat dissipation, the heat dissipation efficiency is low, causing the power transmission and transformation equipment to maintain a high temperature during operation, affecting the stability of the equipment operation. In addition, there is also the problem of more rain and snow in high-altitude areas. Therefore, under such environmental conditions, the power transmission and transformation equipment's own casing alone is difficult to protect against rain and snow. If the casing becomes damp, it is easy to affect the electrical components inside the power transmission and transformation equipment, which in turn causes the power transmission and transformation equipment to malfunction, resulting in a shorter service life of the equipment.

[0003] Traditionally, protective covers are installed outside power transmission and transformation equipment to protect them from rain and snow. However, if the protective covers are fixed outside the power transmission and transformation equipment, on the one hand, they will affect the heat dissipation of the power transmission and transformation equipment. On the other hand, fixed protective covers are difficult to remove, which will also affect the maintenance efficiency of the power transmission and transformation equipment.

[0004] Chinese patent publication number CN116564651A discloses an adjustable protection mechanism and a high-voltage transformer. The baffles are mounted on each other using a plurality of connectors to form a protective cover. Each baffle is a grid structure. However, due to the environmental influences of high altitude areas, the heat dissipation of the power transmission and transformation equipment itself is poor. Therefore, even if the grid has a certain heat dissipation effect, it still cannot reduce the temperature of the power transmission and transformation equipment. Therefore, it cannot solve the problem of the power transmission and transformation equipment operating in a high-temperature state, which affects the operational stability of the equipment.

[0005] Therefore, we propose a power transmission and transformation equipment that can improve heat dissipation efficiency and has high protection. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Example 1

[0041] As attached Figure 1-Figure 4As shown, a high-altitude power transmission and transformation equipment with a variable weather-resistant protective mechanism includes a fixed bracket 1 and a power transmission and transformation equipment body 2 fixed to the fixed bracket 1 by bolts; a protective plate 3 is provided above the power transmission and transformation equipment body 2, and each of the four edges of the protective plate 3 has a groove, into which a fence protection mechanism 4 is inserted, and the bottoms of the multiple fence protection mechanisms 4 are fixedly connected to the fixed bracket 1; and a filler plate is fixedly provided between two adjacent fence protection mechanisms 4;

[0042] There is a certain distance between the four grooves, so that the four fence protection mechanisms 4 are not connected to each other, but there is a certain distance between each other, so that the filling plate can fill the distance, so that the four fence protection mechanisms 4 are connected to form a whole, and then the protective plate 3, the fence protection mechanism 4 and the filling plate together constitute the external protective shell structure of the power transmission and transformation equipment body 2; It should be noted that although the protective plate 3 and the four fence protection mechanisms 4 are plug-in connections, they can be fixed with bolts or other connecting parts to improve the stability of the connection between the external protective shell structures, thereby improving the overall protection effect, and when the power transmission and transformation equipment body 2 needs to be repaired, it is only necessary to remove the bolts and separate the protective plate 3 and the fence protection mechanism 4, which does not affect the maintenance efficiency;

[0043] In particular, the filling plate is configured to be arc-shaped, which can reduce the wind resistance of the external protective shell structure and further improve the overall stability of the external protective shell structure.

[0044] The protection plate 3 is provided with a driving mechanism 5 for changing the opening size of the fence, and a control module 6 for sending a control signal to the driving mechanism 5;

[0045] By changing the size of the fence opening, the fence protection mechanism 4 can simultaneously play a protective and heat dissipation role. When the fence opening is controlled to become smaller, it can prevent rain and snow from entering the internal power transmission and transformation equipment body 2, thereby playing a protective role. When the fence opening is controlled to become larger, the internal air flow rate can be increased to play a heat dissipation role. The control unit can automatically adjust the fence opening size of the fence protection mechanism 4 according to the environment, thereby improving the intelligence level of the power transmission and transformation equipment body 2.

[0046] Example 2

[0047] As an embodiment, the fence protection mechanism 4 includes a frame 41, the top of the frame 41 is plugged into the corresponding groove, the bottom of the frame 41 is fixedly connected to the fixed bracket 1, and a plurality of parallel rotating shafts 42 are provided in the frame 41 for rotation in the vertical direction, and the shaft body of the rotating shaft 42 is installed with a blade 43; the tops of the plurality of rotating shafts 42 pass through the frame 41 and are correspondingly connected to the driving mechanism 5;

[0048] By driving the rotating shaft 42 to rotate through the driving mechanism 5, and then driving the blades 43 to rotate, the size of the fence opening can be adjusted. If the rotating shaft 42 rotates continuously, the heat dissipation effect of the power transmission and transformation equipment body 2 can also be improved. In addition, in this embodiment, the driving mechanism 5 can be a plurality of motors, each of which is connected to a rotating shaft 42 for driving, so that each rotating shaft 42 can move independently. And only the rotation sequence of each rotating shaft 42 needs to be controlled to avoid collision between the blades 43.

[0049] It should be noted that the blade 43 of each shaft 42 is a single piece, and the blade 43 of each shaft 42 is initially parallel to the frame surface of the frame 41, and the gap between adjacent shafts 42 and blades 43 is maintained at 0.5-0.8 mm. Figure 3 As shown, in the front view of each fence protection mechanism 4, the gap between the leftmost rotating shaft 42 blade 43 and the corresponding inner side surface of the frame 41 is also maintained at 0.5-0.8 mm. In addition, between the rightmost rotating shaft 42 and the corresponding inner side surface of the frame 41, a compensation plate 44 is used to be provided. Therefore, when the fence protection mechanism 4 is in the initial state, the rotating shaft 42, blade 43 and compensation plate 44 can relatively form a plane, thereby almost filling the frame 41 and playing a role in protecting against rain and snow.

[0050] An extension rod is provided at each end of the compensation plate 44. The two extension rods are plugged into the inner top and inner bottom surfaces of the frame 41, respectively. The extension rods are connected to the corresponding plug-in holes via a torsion spring; that is, the two ends of the torsion spring are fixedly connected to the extension rod and the frame 41, respectively.

[0051] The initial state of the compensation plate 44 is parallel to the frame surface of the frame 41, and when the previous rotating shaft 42 drives the blade 43 to rotate continuously, it will come into contact with the compensation plate 44. The torsion spring can allow the compensation plate 44 to rotate a certain angle accordingly, thereby reducing the interference with the rotation of the previous rotating shaft 42, and the torsion spring can also allow the compensation plate 44 to return to its initial state when the previous rotating shaft 42 stops rotating.

[0052] Example 3

[0053] As an embodiment, the driving mechanism 5 includes a first transmission gear 51, a second transmission gear 52, a transmission shaft 53, a first driving gear 54, a second driving gear 55 and a motor 56;

[0054] The plurality of first transmission gears 51 are respectively installed with clearances corresponding to the plurality of rotating shafts 42, and the plurality of second transmission gears 52 are respectively connected to the plurality of first transmission gears 51 through chains.

[0055] The second transmission gears 52 are respectively installed with clearance fit on the plurality of transmission shafts 53 in a one-to-one correspondence. A first drive gear 54 is installed with clearance fit on each transmission shaft 53. The first drive gears 54 are transmission-connected to the second drive gears 55 via chains. The second drive gears 55 are clearance fit connected to the output shaft of the motor 56.

[0056] The transmission process is as follows: the second driving gear 55 is driven to rotate by the motor 56, and under the transmission action of the chain, multiple second driving gears 55 are driven to rotate synchronously, and each second driving gear 55 can drive the corresponding transmission shaft 53 to rotate, and each transmission shaft 53 thereby drives the corresponding second transmission gear 52 to rotate, and the second transmission gear 52 finally drives the corresponding first transmission gear 51 to rotate through the chain, thereby driving the rotating shaft 42; if the motor 56 is operated for a short time, the angle of the vane 43 can be adjusted, and if the motor 56 is operated continuously, the rotating shaft 42 and the vane 43 can be continuously rotated;

[0057] It should be noted that, combined with Figure 2 As shown, the second transmission gear 52 and the first drive gear 54 are both mounted on the same transmission shaft 53, and the two can realize synchronous rotation through the transmission shaft 53, and Figure 2 The first drive gear 54 is shown in FIG. 5 , and the second transmission gear 52 is hidden below the first drive gear 54 , but the chain transmission relationship is retained. Figure 4 As shown, the principle of chain transmission between gears is to insert the teeth of the gears into the holes on the chain, so that the gears and the chain form a whole and have a transmission effect. When multiple first drive gears 54 and the second drive gears 55 are transmitted through the chain, the teeth of the multiple gears are also inserted into the corresponding holes on the chain.

[0058] In another embodiment of the present invention, the number of rotating shafts 42 is even, and the plurality of first drive gears 54 are sequentially divided into two equal groups. Two second drive gears 55 are provided, and the two second drive gears 55 are respectively connected to the output shaft of a motor 56 with a clearance fit, and each group of first drive gears 54 is connected to one second drive gear 55 via a chain.

[0059] That is, by driving the two sets of rotating shafts 42 separately through two motors 56, the diversity of the angle adjustment of the blades 43 can be improved. When the wind direction is the positive direction of a certain fence protection mechanism 4, the angles of the blades 43 of the two sets of rotating shafts 42 are adjusted in opposite directions, so that the wind can be diverted, the utilization efficiency of the wind can be improved, and the heat dissipation efficiency of the power transmission and transformation equipment body 2 can be correspondingly improved.

[0060] Example 4

[0061] As an example, Figure 5-Figure 6As shown, the control module 6 includes a wind direction sensor 61, a humidity sensor 62, a temperature sensor 63 and a central controller 64, wherein the wind direction sensor 61 is located on the top of the protective plate 3 and is used to monitor the wind direction data in real time;

[0062] The humidity sensor 62 is located on the top of the protective plate 3 and is used to monitor the external humidity data in real time;

[0063] The temperature sensor 63 is located on the top surface of the protective plate 3 and is used to monitor the temperature data of the power transmission and transformation equipment body 2 in real time;

[0064] The central controller 64 is used to calculate the appropriate fence opening value according to wind direction data, external climate data and temperature data, and output a control signal to the driving mechanism 5 according to the fence opening value.

[0065] In addition, the central controller 64 includes a data receiving unit, a state determination unit, a mode selection unit and a signal output unit;

[0066] The data receiving unit is used to receive the data output by the wind direction sensor 61, the humidity sensor 62 and the temperature sensor 63, and perform pre-processing;

[0067] The state judgment unit is used to judge whether it is rainy or snowy weather according to the humidity data, and to judge whether the power transmission and transformation equipment body 2 is overheating according to the temperature sensor 63;

[0068] The mode selection unit is used to select the fence protection mechanism 4 to be in a corresponding working mode according to the judgment condition output by the state judgment unit and in combination with the wind direction data;

[0069] The signal output unit is used to output corresponding control signals to the driving mechanism 5 according to the corresponding working mode.

[0070] According to needs, the working modes of the mode selection unit include protection mode, heat dissipation mode and operation mode. If it is judged that it is rainy or snowy weather, the protection mode is selected; if it is judged that it is not rainy or snowy weather but the power transmission and transformation equipment body 2 is overheated during operation, the heat dissipation mode is selected; if it is judged that it is not rainy or snowy weather and the power transmission and transformation equipment body 2 is not overheated during operation, the operation mode is selected;

[0071] It should be noted that since rainy and snowy weather is severe and the ambient temperature is generally low, there is no need to dissipate heat for the power transmission and transformation equipment, and it is in protection mode for a long time.

[0072] The protection mode is when the opening of the fence protection mechanism 4 is at its minimum state, specifically when the blades 43 of each shaft 42 are in the initial state described in Example 2;

[0073] In the heat dissipation mode, the drive mechanism 5 drives the shafts 42 to rotate continuously, and the rotation of the shafts 42 and blades 43 drives the heat generated by the power transmission and transformation equipment body 2 to be output to the outside, thereby achieving active heat dissipation.

[0074] In the operation mode, the driving mechanism 5 drives the rotating shaft 42 to rotate a small amount according to the wind direction, so that the edge of the corresponding blade 43 faces the wind direction, allowing the wind to smoothly enter the external protective shell structure, and use the wind to take away the heat of the power transmission and transformation equipment body 2, thereby achieving passive heat dissipation.

[0075] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
