Description

Technical Field

[0001] This invention relates to the field of substation equipment technology, specifically to a mobile substation equipment support. Background Technology

[0002] A mobile substation equipment support frame is a support structure specifically designed for mobile substations. It typically includes a foundation base, support columns, and an equipment mounting platform. The foundation base consists of a steel frame and protective plates. The support columns are vertically fixed to the base, and the equipment mounting platform is connected to the top of the support columns for installing electrical equipment. This support structure is designed for easy disassembly and relocation, while ensuring it is not easily deformed during movement and hoisting, facilitating reinstallation.

[0003] Publication No. CN114640036A discloses a mobile substation equipment support, including a base, supports, and an equipment mounting platform. The base includes a steel frame and first and second protective plates enclosing the steel frame. Four supports are provided, each vertically fixed to one of the four corners of the upper surface of the base. The equipment mounting platform is connected to the end of each support away from the base and includes a first, second, and third mounting platform for installing electrical equipment. This invention is simple to disassemble and easy to move in practical use. It is not easily deformed during movement and hoisting, and restoration and installation are more convenient. This support structure optimizes the structural form and reduces the structural volume and usable space while meeting the safe operating distance requirements for electrical equipment.

[0004] Strong winds can increase the overall vibration amplitude of mobile substation equipment, which may cause bolts to loosen and parts to fall off. Therefore, wind protection needs to be considered when using mobile substation equipment brackets. Some brackets are equipped with movable covers during installation to improve wind protection. While this can effectively improve wind protection, the covers can affect the heat dissipation of substation components inside the bracket, thus affecting the service life of the device. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile substation equipment support to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a mobile substation equipment support, including a support base, the support base including a support frame, a spring damper fixedly connected inside the support frame, a protective plate fixedly connected to the side of the spring damper, a support rod fixedly connected to the side of the protective plate, a fixing rod fixedly connected to the side of the support rod, a control panel fixedly connected to the bottom of the fixing rod, and multiple pressure sensors fixedly connected to the outer surface of the control panel;

[0007] A fixed bracket is installed on the top of the bracket base. The fixed bracket includes a device housing. The device housing has multiple heat dissipation holes. An adjustment plate is rotatably connected to the first row of heat dissipation holes at the tip side of the device housing. A first movable plate is rotatably connected to the adjustment plate. A second movable plate is rotatably connected to the side of the first movable plate. A movable sleeve is rotatably connected to the side of the second movable plate.

[0008] Furthermore, a fixing plate is fixedly connected to the outer shell of the device, and a spring is fixedly connected to the side of the fixing plate. The other end of the spring is fixedly connected to the adjusting plate. When the wind force is strong, the wind blows the adjusting plate into the heat dissipation hole, and the fixing plate and the spring play a buffering role. When the wind force decreases, the spring bounces the adjusting plate back to the initial position.

[0009] Furthermore, the heat dissipation holes have an outward V-shaped structure, with the inner opening being smaller than the outer opening, and the tilt angle is controlled between 15 and 30 degrees. During use, the tilt angle allows dust to slide off naturally under gravity, reducing the frequency of manual cleaning. At the same time, when the equipment vibrates, the tilted hole wall decomposes the impact force into vertical and horizontal components, reducing stress concentration at the edge of the hole and lowering the risk of cracking. The bottom side of the device housing is fixedly connected to a second fixing seat, which is fixed to the support frame with bolts, facilitating installation and disassembly. The structure is stable and not easily deformed during movement and hoisting.

[0010] Furthermore, a fixed base is fixedly connected to the top of the movable sleeve. The movable sleeve and the fixed base are embedded inside the outer shell of the device. A dustproof net is fixedly connected to the movable sleeve. When the adjustment plate is in its natural state, the dustproof net is set on the side of the heat dissipation hole, and two-thirds of the heat dissipation hole is located at the dustproof net. Heat is dissipated through the heat dissipation hole. In the absence of wind, the efficiency is two-thirds of that of the heat dissipation hole, which can meet the normal heat dissipation requirements.

[0011] Furthermore, the bottom of the support frame is fixedly connected to the support rod, a movable disc is rotatably connected to the support frame, a motor is fixedly connected to the center of the bottom of the support frame, the output shaft of the motor is fixedly connected to the movable disc, and a spring damping device is fixedly connected to the bottom of the guard plate. The spring damper and the guard plate reduce the vibration amplitude of the device in the horizontal direction, and the spring damping device reduces the vibration amplitude in the vertical direction, thereby achieving a wind-resistant effect.

[0012] Furthermore, a support plate is fixedly connected to the top of the movable plate, and the support plate has an installation groove.

[0013] Furthermore, a streamlined slot is provided at the center of the adjustment plate, which allows airflow to pass quickly from the outside, reducing wind resistance and lowering the vibration amplitude of the device.

[0014] Furthermore, the fixed bracket is internally equipped with a control system, including a data receiving unit, a data processing unit, and a drive unit. The data receiving unit is used to receive pressure sensor signals, the data processing unit analyzes pressure data, and the drive unit controls the motor to rotate. Beneficial effects

[0015] When the adjustable plate of this mobile substation equipment support is in its natural position, the dustproof net covers two-thirds of the heat dissipation holes. In the absence of wind, the heat dissipation efficiency is two-thirds of the hole area, meeting normal heat dissipation requirements while preventing dust and rain. When the adjustable plate moves, it links the first and second movable plates and the movable sleeve, causing the dustproof net to move completely outwards and the heat dissipation holes to open fully. When air passes through the heat dissipation holes, the wind speed is high and the pressure is low on the outer casing surface, forcing the gas inside the holes out. External air is forced in from the far end, accelerating internal air circulation and preventing uneven heat dissipation caused by the closure of the heat dissipation holes on the windward side, ensuring efficient and stable operation of the equipment.

[0016] In use, the mobile substation equipment support effectively reduces vibration in the vertical direction thanks to the spring damping device. In the horizontal direction, the guard plate and the spring damper work together to further reduce vibration. When the wind is strong, the device vibration causes a slight displacement, triggering the pressure sensor on the control panel. The sensor data is processed by the module and compared with the standard value. If the value exceeds the standard, the motor is driven to rotate, aligning the tip of the fixed support with the wind direction. The streamlined structure reduces wind resistance, effectively reducing vibration intensity and ensuring stable operation of the device. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 , Figures 3-5 A mobile substation equipment support includes a support base 1, the support base 1 includes a support frame 101, a spring damper 110 is fixedly connected inside the support frame 101, a guard plate 106 is fixedly connected to the side of the spring damper 110, a support rod 105 is fixedly connected to the side of the guard plate 106, a fixing rod 108 is fixedly connected to the side of the support rod 105, a control panel 109 is fixedly connected to the bottom of the fixing rod 108, and multiple pressure sensors are fixedly connected to the outer surface of the control panel 109.

[0027] The bottom of the support frame 101 is fixedly connected to the support rod 105. A movable disk 102 is rotatably connected to the support frame 101. A motor 107 is fixedly connected to the center of the bottom of the support frame 101. The output shaft of the motor 107 is fixedly connected to the movable disk 102. A spring damping device 111 is fixedly connected to the bottom of the guard plate 106. The vibration amplitude in the horizontal direction of the device is reduced by the spring damper 110 and the guard plate 106, and the vibration amplitude in the vertical direction is reduced by the spring damping device 111, thereby achieving a wind-resistant effect.

[0028] A support plate 103 is fixedly connected to the top of the movable plate 102, and an installation groove 104 is provided on the support plate 103.

[0029] The fixed bracket 2 is equipped with a control system, including a data receiving unit, a data processing unit, and a drive unit. The data receiving unit is used to receive pressure sensor signals, the data processing unit analyzes pressure data, and the drive unit controls the rotation of the motor 107.

[0030] In this embodiment, it is necessary to specifically explain that after installation, the substation components are fixed on the top of the support plate 103, and the cables are brought out from the mounting groove 104. In the vertical direction, the vibration amplitude is reduced by the spring damping device 111, and in the horizontal direction, the vibration amplitude is reduced by the guard plate 106 and the spring damper 110. When the wind is strong, the device will vibrate under the action of the wind. The vibration causes the device to deviate slightly, so that the pressure sensor on the control plate 109 comes into contact with the support frame 101. The pressure sensor generates a value after being subjected to force. The value is transmitted to the data processing module through the data receiving unit. The data processing module compares the sensor detection value with the standard value. The standard value is the maximum value of the pressure sensor that does not affect the stability of the device under the action of wind. If it is greater than the standard value, the drive unit controls the motor 107 to rotate, so that the tip of the fixed bracket 2 is aligned with the opposite direction of the pressure sensor output, that is, aligned with the direction of the wind. The streamlined structure of the fixed bracket 2 is used to reduce wind resistance and reduce vibration intensity.

[0031] Please see Figures 1-2 , Figures 6-7 A fixed bracket 2 is installed on the top of the bracket base 1. The fixed bracket 2 includes a device housing 201. Multiple heat dissipation holes 202 are provided on the device housing 201. An adjustment plate 3 is rotatably connected to the first row of heat dissipation holes 202 at the tip side of the device housing 201. A first movable plate 205 is rotatably connected to the adjustment plate 3. A second movable plate 206 is rotatably connected to the side of the first movable plate 205. A movable sleeve 204 is rotatably connected to the side of the second movable plate 206.

[0032] A fixing plate 4 is fixedly connected to the outer casing 201 of the device. A spring 5 is fixedly connected to the side of the fixing plate 4. The other end of the spring 5 is fixedly connected to the adjusting plate 3. When the wind is strong, the adjusting plate 3 is blown into the heat dissipation hole 202 by the wind. The fixing plate 4 and the spring 5 play a buffering role. When the wind decreases, the spring 5 will bounce the adjusting plate 3 back to the initial position.

[0033] The heat dissipation hole 202 has an outward V-shaped structure with a smaller inner opening and a larger outer opening. The tilt angle is controlled between 15 and 30 degrees. During use, the tilt angle allows dust to slide off naturally under gravity, reducing the frequency of manual cleaning. At the same time, when the equipment vibrates, the tilted hole wall decomposes the impact force into vertical and horizontal components, reducing stress concentration at the edge of the hole and lowering the risk of cracking. The bottom side of the device housing 201 is fixedly connected to the fixing seat 208. The fixing seat 208 is fixed to the support frame 101 by bolts, which facilitates installation and disassembly. The structure is stable and is not easily deformed during movement and hoisting.

[0034] The top of the movable sleeve 204 is fixedly connected to a fixing seat 203. The movable sleeve 204 and the fixing seat 203 are embedded inside the outer shell 201 of the device. A dustproof net 207 is fixedly connected to the movable sleeve 204. When the adjusting plate 3 is in the natural state, the dustproof net 207 is set on the side of the heat dissipation hole 202 and two-thirds of the heat dissipation hole 202 is located at the dustproof net 207. Heat is dissipated through the heat dissipation hole 202. In the absence of wind, the efficiency is two-thirds of that of the heat dissipation hole 202, which can meet the normal heat dissipation requirements.

[0035] A support plate 103 is fixedly connected to the top of the movable plate 102, and an installation groove 104 is provided on the support plate 103.

[0036] A streamlined slot is provided at the center of the regulating plate 3, which allows airflow to pass quickly through the outside of the regulating plate 3, reducing wind resistance and lowering the vibration amplitude of the device.

[0037] In this embodiment, it should be specifically explained that during use, by aligning the tip of the fixed bracket 2 with the opposite direction of the wind, the streamlined structure reduces wind resistance. At the same time, when the fixed bracket 2 faces the wind, the adjusting plate 3 seals the heat dissipation hole 202 at the tip of the device housing 201, preventing strong winds from causing airflow turbulence inside the equipment through the heat dissipation hole 202, which would lead to increased electromagnetic interference, aggravated mechanical vibration, and reduced service life of the substation equipment. It can also prevent dust, sand, and insects carried by the wind from entering. The dustproof net 207 is also more prone to damage when facing the wind directly, thus affecting the interception effect.

[0038] When the adjusting plate 3 is in its natural state, the dustproof net 207 is located on the side of the heat dissipation hole 202, with two-thirds of the heat dissipation hole 202 located at the dustproof net 207 and the other one-third located at the movable sleeve 204. Heat is dissipated through the heat dissipation hole 202, achieving two-thirds of the efficiency of the heat dissipation hole 202 in a windless state, which meets normal heat dissipation needs and prevents dust and rainwater from entering. When the adjusting plate 3 moves towards the heat dissipation hole 202, it drives the first movable plate 205, which is rotatably connected to it, to move. The first movable plate 205 drives the second movable plate 206 to move in the opposite direction to the tip of the device housing 201. The second movable plate 206 drives the movable sleeve 204 and the fixed seat 203 to move. The fixed seat 203 is located on the device housing 201. The internal rotation of the device housing 201 adjusts the position of the dustproof net 207 on the movable sleeve 204, so that the heat dissipation hole 202 is completely outside the dustproof net 207. The heat dissipation hole 202 is used entirely for heat dissipation. At the same time, when the wind blows across the surface of the heat dissipation hole 202, the wind speed on the outer surface of the device housing 201 is greater than the wind speed at the heat dissipation hole 202. According to Bernoulli's principle, the faster the flow velocity, the lower the pressure, and the slower the flow velocity, the higher the pressure. This causes the gas inside the heat dissipation hole 202 on the side of the regulating plate 3 to be squeezed out by atmospheric pressure. The external atmospheric pressure forces the gas in from the heat dissipation hole 202 at the farthest end of the regulating plate 3, thereby accelerating the air circulation inside the fixed bracket 2 and avoiding uneven heat dissipation caused by the closure of the heat dissipation hole 202 at the windward side.
