DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 7As shown, the present embodiment provides a high temperature prevention and control device for electric power equipment, comprising: an electric power cabinet body 100, a detection mechanism, a driving mechanism 300 and a prevention and control mechanism 400; the prevention and control mechanism 400 is located in the electric power cabinet body 100, one side of the prevention and control mechanism 400 is hinged to the inner wall of the electric power cabinet body 100, and the other side is clamped to the inner wall of the electric power cabinet body 100, and a storage space 500 for accommodating sand is formed between the prevention and control mechanism 400 and the electric power cabinet body 100; the driving mechanism 300 is transmission-connected to the prevention and control mechanism 400, the detection mechanism is used to detect smoke information in the electric power cabinet body 100, and the driving mechanism 300 is opened according to the smoke information to drive the prevention and control mechanism 400 to separate from the electric power cabinet body 100, so that the sand in the storage space 500 falls into the electric power cabinet body 100.

[0038] It should be noted that the high-temperature prevention and control device for electric power equipment provided in this embodiment can use the detection mechanism to monitor the smoke information inside the power cabinet body 100 in real time when there is open flame and smoke in the early stage, and can control the driving mechanism 300 to open after the smoke exceeds the preset smoke value threshold, and use the driving mechanism 300 to drive the prevention and control mechanism 400 to separate from the power cabinet body 100, so that the sand in the storage space 500 falls into the power cabinet body 100 under the action of gravity, and the open flame is eliminated by burying the sand, thereby reducing the possibility of fire in the power cabinet.

[0039] Optionally, the top of the power cabinet body 100 can be set to an open cover or a sand adding window. When other power components inside the power cabinet body 100 are installed, sand is added to the storage space 500 using the open cover structure or the adding window. At the same time, it should be noted that the edge position of the storage space 500 formed by the prevention and control mechanism 400 and the inside of the power cabinet body 100 needs to be sealed to ensure that the sand is stored in the storage space 500 as much as possible when the prevention and control mechanism 400 is not opened.

[0040] The present embodiment provides a high temperature prevention and control device for electric power equipment, comprising: an electric power cabinet body 100, a detection mechanism, a driving mechanism 300 and a prevention and control mechanism 400; the prevention and control mechanism 400 is located in the electric power cabinet body 100, the prevention and control mechanism 400 is located at the top of the electric power cabinet body 100, one side of the prevention and control mechanism 400 is hinged to the inner wall of the electric power cabinet body 100, and the other side is clamped to the inner wall of the electric power cabinet body 100, and a storage space 500 for accommodating sand is formed between the prevention and control mechanism 400 and the electric power cabinet body 100; the driving mechanism 300 is transmission-connected to the prevention and control mechanism 400, and the start signal of the driving mechanism 300 is when the detection mechanism receives a smoke alarm. After the alarm signal is sent, the detection mechanism is connected to the driving mechanism 300 by electrical signal. The detection mechanism is used to detect the smoke information inside the power cabinet body 100. When the smoke information is detected to reach a preset smoke threshold, the driving mechanism 300 is turned on to drive the prevention and control mechanism 400 to separate from the power cabinet body 100, so that the sand in the storage space 500 falls into the power cabinet body 100. The sand can be used to extinguish the open fire as soon as there is smoke inside the power cabinet body 100, thereby alleviating the technical problem in the prior art that when the temperature of the power cabinet is abnormal, the open fire in the power cabinet cannot be extinguished in time, thereby causing damage to the power cabinet or even causing a fire.
