Description

Technical Field

[0001] This utility model relates to the field of high-voltage power control cabinet technology, specifically a high-voltage power control cabinet with a protective mechanism. Background Technology

[0002] High-voltage power control cabinets, also known as high-voltage switchgear, are used in power systems for power generation, transmission, distribution, energy conversion, and consumption, and play a role in switching, controlling, or protecting the circuits. High-voltage power control cabinets are mainly used to install switches that control high-voltage circuits and are often installed outdoors.

[0003] Publication No. CN221150703U discloses a high-voltage power control cabinet with a protective mechanism. Through the cooperation of a stand, threaded rod, lifting seat, waterproof motor, rain cover, support base, support rod, support plate, support spring, sleeve, buffer rod, buffer spring, and buffer plate, the control cabinet body can be raised when not in use, preventing children from touching the cabinet body and causing danger, thus further improving the safety of the equipment. It also increases the installation height of the control cabinet body, preventing water seepage during heavy rain, providing a waterproof function. Furthermore, the rain cover can buffer and dissipate force in the event of falling objects from a height, further improving the protection of the control cabinet body. Additionally, the control cabinet body can be lowered when the high-voltage switch inside needs to be installed or repaired, further improving ease of use. However, this patent still has the following problems in actual use:

[0004] While the high-voltage power control cabinet with protective mechanisms can be raised when not in use to prevent children from touching it and causing danger, thus further improving the safety of the equipment, the fact that it is placed outdoors without any protection poses a risk of leakage. When people pass by the cabinet, they may accidentally touch it, resulting in electric shock, which is a safety hazard and detrimental to people's lives.

[0005] Therefore, a high-voltage power control cabinet with a protective mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-voltage power control cabinet with a protective mechanism moves the first isolation protective net, the second isolation protective net, and the rotating protective net to the outside of the control cabinet body.

At the same time, the lifting threaded sleeve drives the lifting connecting rod and the first isolation and protection net to move up and down, moving the first isolation and protection net, the second isolation and protection net, and the rotating protection net to the outside of the control cabinet body. This not only provides safety protection for the control cabinet body but also avoids the risk of electric shock caused by people accidentally touching the control cabinet body. By pulling the unlocking connecting plate, the locking pin and the locking sliding sleeve move to the outside of the locking sliding rod. When the locking pin separates from the locking pin, the rotating protection net can be opened under the action of the rotating support, facilitating the maintenance of the control cabinet body. The dimensions of the first isolation and protection net, the second isolation and protection net, and the rotating protection net can be designed according to the actual situation to separate and protect the control cabinet body. At the same time, the lock at the locking bracket can be replaced to prevent children from accidentally opening the rotating protection net.

[0021] 2. By setting up a cabinet heat dissipation mechanism, not only can the installation of control cabinet components be facilitated and heat dissipation be achieved through the ventilation mounting plate, but the cooling fan can also be started to blow the first rotating louver to a horizontal position. At the same time, the rotating motor can be started to drive the second sprocket transmission assembly to rotate. By utilizing the characteristic of the second sprocket transmission assembly and the meshing sprocket, the rotation of the second rotating louver can be achieved, thereby facilitating rapid ventilation and heat dissipation of the interior of the control cabinet.

Utilizing the meshing connection between the second sprocket transmission assembly 214 and the meshing sprockets 215, the second rotating louver 216 is rotated, thereby facilitating rapid ventilation and heat dissipation inside the control cabinet body 201.

[0032] Working principle: Before using this type of high-voltage power control cabinet with protective mechanisms, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, the ventilation mounting plate 202 facilitates the installation of control cabinet components and heat dissipation. Simultaneously, the cooling fan 209 is activated to move the first rotating louver 210 to a horizontal position. At the same time, the rotating motor 213 drives the second sprocket transmission assembly 214 to rotate. Utilizing the meshing connection between the second sprocket transmission assembly 214 and the meshing sprocket 215, the second rotating louver 216 rotates, thus facilitating rapid ventilation and heat dissipation inside the control cabinet body 201. Secondly, the lifting motor 104 drives the first sprocket transmission assembly 105 and the lifting rotating rod 106 to rotate, causing the bevel gear transmission assembly 107 to drive the lifting threaded rod 108 to rotate. Simultaneously, the lifting threaded sleeve 109 drives the lifting connecting rod 110 and the first isolation protective net 111 to move up and down, thus moving the first isolation protective net 111 and the second isolation protective net 112. The rotating protective net 114 is moved to the outside of the control cabinet body 201, which not only provides safety protection for the control cabinet body 201, but also avoids the risk of electric shock caused by people accidentally touching the control cabinet body 201. Finally, by pulling the unlocking connecting plate 120, the locking pin 119 and the locking sliding sleeve 117 are moved to the outside of the locking sliding rod 116. When the locking pin 119 is separated from the locking pin 116, the rotating protective net 114 can be opened under the action of the rotating support 113, which facilitates the maintenance of the control cabinet body 201. The dimensions of the first isolation protective net 111, the second isolation protective net 112 and the rotating protective net 114 can be designed according to the actual situation, so as to separate and protect the control cabinet body 201. At the same time, the lock at the locking bracket 115 can be replaced to prevent children from accidentally opening the rotating protective net 114.
