[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention; See also Figure 1-6In the present invention, a movable high and low voltage switch cabinet with monitoring function includes a base 1, a support platform 2 is slidably installed on the top of the base 1, a cabinet 3 is rotatably installed on the top of the support platform 2, a notch 4 is provided at the bottom of the left corner of the front of the cabinet 3, a positioning mechanism 5 is installed inside the notch 4, the positioning mechanism 5 is engaged with the support platform 2 at the bottom, an intermediate groove 6 is provided on the base 1, a horizontal plate 7 is fixedly installed inside the intermediate groove 6, a driving mechanism 8 is installed at the bottom of the support platform 2, the driving mechanism 8 is connected and matched with the horizontal plate 7, two busbar connectors 9 are installed inside the cabinet 3, a first temperature sensor 10 is fixedly sleeved on the outer side of the busbar connector 9, an opening and closing door 11 is installed on the front of the cabinet 3, a display controller 12 is installed on the opening and closing door 11, a communication module 13 is installed on the top of the display controller 12, the communication module 13 is connected to the 5G network and is connected to the control terminal for communication, an air cooling mechanism 14 is installed on the top of the cabinet 3, and the bottom of the air cooling mechanism 14 extends downward to the inside of the cabinet 3.

[0019] In the present invention, the base 1 is used as the installation support of the device. When in use, the base 1 is installed at the position of the cabinet 3, and the cabinet 3 is installed and supported by the support platform 2. First, when the cabinet 3 is in operation, the temperature at the two busbar joints 9 is relatively high. The first temperature sensor 10 is used to monitor the temperature of the two busbar joints 9 separately and independently, and the temperature is displayed in real time on the display controller 12, which is convenient for patrol and maintenance personnel to view. At this time, the air cooling mechanism 14 is started to assist in heat dissipation inside the cabinet 3 to ensure the normal operation of the equipment, and the display controller 12 transmits the temperature data to the control terminal using the communication module 13 to realize remote monitoring of the equipment operation.

[0020] When the equipment needs to be repaired, the cabinet 3 needs to be moved forward. The driving mechanism 8 is first rotated to move along the inside of the cross plate 7 to drive the support platform 2 to slide forward in a straight line along the top of the base 1, so as to drive the cabinet 3 to move forward, and this method of movement and adjustment is very stable to prevent the cabinet 3 from shaking. After the support platform 2 moves forward, if other surfaces of the cabinet 3 need to be repaired and maintained, the positioning mechanism 5 is released. At this time, the cabinet 3 can be flexibly rotated on the support platform 2 to adjust the direction of different surfaces to the maintenance personnel. After the maintenance is completed, the positioning mechanism 5 is used to accurately position the cabinet 3 and the support platform 2, and the driving mechanism 8 is rotated to drive the support platform 2 to be accurately reset, which can realize flexible and convenient movement and adjustment of the cabinet 3. During maintenance, the cabinet 3 is always in a stable state without shaking or offset, thereby protecting the external connection harness and the safety of maintenance personnel, and the resetting operation is more accurate and labor-saving. During installation, there is no need to repeatedly align the installation holes, and the operation is convenient, efficient and labor-saving, so that the device can realize online monitoring of the operating temperature of the equipment. At the same time, it is very labor-saving and convenient to move the switch cabinet during maintenance, and the stability of the switch cabinet during maintenance is maintained. The reset operation is more accurate, convenient and labor-saving. It solves the problem in the prior art that during maintenance and repair, the entire switch cabinet often needs to be moved for maintenance. Generally, the moving distance is short, and it is required to be reset after maintenance. The current fixing method requires the switch cabinet to be disassembled as a whole, and it is more laborious to move after disassembly, and the reset is also laborious. It is not easy to align the bolt installation holes, and the operation is difficult. At the same time, temperature sensors are generally installed inside the equipment to monitor the temperature of important component node positions. However, due to cost constraints, the number of sensors is limited, and it is difficult to comprehensively monitor the temperature changes inside the entire equipment.

[0021] See also Figure 3 and Figure 5 , wherein: the air cooling mechanism 14 includes a fan 141, a shroud 142 and an air duct 143, the fan 141 is fixedly installed on the top of the cabinet 3, the shroud 142 is fixedly installed on the top of the fan 141, the top of the air duct 143 is connected and fixed to the fan 141, the bottom end of the air duct 143 passes through and is fixedly connected to the interior of the cabinet 3, and the outer side of the air duct 143 is provided with double rows of holes 144 arranged at equal distances.

[0022] In the present invention, the high-temperature air inside the cabinet 3 is extracted by starting the fan 141 and using the air duct 143, so that the external air enters the circulation, and continuous air cooling is achieved inside the cabinet 3. The air guide cover 142 on the top guides the airflow from the air outlet of the fan 141 to make it flow out smoothly and achieve the effect of preventing dust and foreign matter. The double rows of holes 144 on the air duct 143 are arranged vertically and aligned with the gaps between components inside the cabinet 3, so as to achieve a better airflow effect.

[0023] See also Figure 2 , wherein: a vertical rod 145 is fixedly connected to the top of the air duct 143, and a wind speed sensor 146 and a second temperature sensor 147 are vertically arranged on the vertical rod 145, and the output ends of the wind speed sensor 146 and the second temperature sensor 147 are electrically connected to the input end of the display controller 12.

[0024] In the present invention, the air flow velocity and temperature inside the duct 143 are monitored in real time by the wind speed sensor 146 and the second temperature sensor 147 on the vertical rod 145. First, the wind speed monitoring can grasp the working status of the fan 141 in real time, and judge whether there is blockage at the air inlet and outlet, so as to quickly grasp the operating status of the air cooling mechanism 14. At the same time, the temperature of the exhaust air flow is monitored in conjunction with the second temperature sensor 147, and the temperature threshold when the equipment is operating normally is set as a limit. When the air flow temperature detected by the second temperature sensor 147 is abnormal, the display controller 12 will simultaneously judge whether the value of the wind speed sensor 146 changes. If the wind speed remains unchanged, the temperature inside the cabinet 3 increases, and the detected temperature at the busbar connector 9 is normal, then a judgment is issued that the temperature of other electrical components inside the cabinet 3 is abnormal. In this way, both the monitoring and judgment of the operating status of the air cooling mechanism 14 and the monitoring of the overall temperature environment inside the cabinet 3 can be realized. The temperature of other electrical components is judged by the elimination method, thereby realizing a more comprehensive monitoring of the temperature environment inside the cabinet 3.

[0025] See also Figure 1 and Figure 4 , wherein: the positioning mechanism 5 includes a vertical screw 51 and a toggle sleeve 52, the top end of the vertical screw 51 passes through and is threadedly connected to the interior of the cabinet 3, the toggle sleeve 52 is sleeved to the outside of the vertical screw 51, and a positioning hole 21 is opened on the support platform 2 to engage with the bottom end of the vertical screw 51.

[0026] In the present invention, the vertical screw 51 is driven to rotate by the toggle sleeve 52, so that the vertical screw 51 moves vertically along the inside of the cabinet 3, so as to separate the vertical screw 51 from the positioning hole 21, thereby releasing the positioning of the cabinet 3, allowing it to rotate flexibly on the support platform 2 for easy maintenance. When resetting the installation, the vertical screw 51 is used to position the cabinet 3 and the support platform 2 to stabilize their installation structure.

[0027] See also Figure 1 and Figure 2 , wherein: the driving mechanism 8 includes a positioning block 81, an adjusting rod 82 and a hand-cranked disk 83, the top of the positioning block 81 is fixedly mounted to the bottom of the support platform 2, one end of the adjusting rod 82 is rotatably connected to the positioning block 81, the other end of the adjusting rod 82 passes through and is threadedly connected to the front side of the cross plate 7, and the front end of the adjusting rod 82 is fixedly connected to the hand-cranked disk 83.

[0028] In the present invention, the adjusting rod 82 is driven to rotate by the hand crank 83, and the adjusting rod 82 moves linearly along the horizontal plate 7, so as to drive the positioning block 81 and the support platform 2 to slide linearly along the top of the base 1, so as to realize the outward movement of the adjustment cabinet 3, so as to facilitate inspection and maintenance. At the same time, after the inspection is completed, the subsequent resetting and installation operation is more accurate, convenient and labor-saving.

[0029] See also Figure 1 and Figure 2 , wherein: two grooves 15 are opened on the front of the base 1 , and two rollers 16 are installed at the bottom of the support platform 2 , and the two rollers 16 are respectively located inside the two grooves 15 .

[0030] In the present invention, the two rollers 16 ensure that the support platform 2 always maintains good support when moving forward, reduces movement resistance, and is more convenient to operate. The grooves 15 allow the rollers 16 to be retracted after the support platform 2 is reset, and do not protrude, thereby ensuring that the exterior of the mechanism is flat.

[0031] See also Figure 3 and Figure 6 , wherein: two parallel guide blocks 22 are fixedly connected to the bottom of the support platform 2, and two parallel slide grooves 17 matching the guide blocks 22 are provided on the base 1.

[0032] In the present invention, the guide block 22 cooperates with the parallel slide groove 17 to make the support platform 2 slide on the base 1 more stable and safe, and less likely to deviate.

[0033] See also Figure 1 and Figure 3 , wherein: ventilation windows 18 are provided on both sides of the cabinet 3.

[0034] In the present invention, when the fan 141 draws air through the ventilation window 18, the external cold air smoothly enters the interior of the cabinet 3 to achieve circulating air cooling.

[0035] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
