Description

Technical Field

[0001] This invention belongs to the field of power monitoring equipment technology, and more specifically, relates to a power monitoring device with a protection device. Background Technology

[0002] Electricity is an energy source that uses electrical energy as its power source. Large-scale power systems are one of the most important achievements in the history of human engineering science. They are power production and consumption systems composed of power generation, transmission, transformation, distribution, and consumption. They convert primary energy from nature into electricity through mechanical energy devices, and then supply the electricity to various users through transmission, transformation, and distribution. This process requires the use of various electrical equipment. Currently, electrical equipment needs to be inspected regularly. Power monitoring equipment can effectively monitor power equipment, promptly identify faults in the power monitoring equipment, and avoid affecting the normal operation of the power monitoring equipment.

[0003] A search revealed that authorization announcement number CN219224855U discloses a power monitoring device with a protection mechanism, comprising a base, a power monitoring housing fixedly connected to the top of the base, an inlet housing connected to the bottom of the back of the power monitoring housing, a clamping assembly located on the back of the power monitoring housing and at the top of the inlet housing, heat dissipation vents on the top of both sides of the power monitoring housing, baffles on both sides of the inner cavity of the power monitoring housing, a motor fixedly connected to the rear of the inner cavity of the base, a rotating disk fixedly connected to the front of the motor output end, and a rotating block fixedly connected to the front of the rotating disk. Through the combined use of the base, power monitoring housing, inlet housing, clamping assembly, heat dissipation vents, baffles, motor, rotating disk, rotating block, lifting housing, lifting frame, protective housing, rain sensor, buffer box, first spring, and buffer frame, the problem of the relatively simple protection function of existing power monitoring devices is solved.

[0004] However, existing power detection boxes often fail to provide timely warnings and effective handling if fire hazards arise, which can easily lead to greater losses.

[0005] To address the aforementioned problems, this application proposes a power monitoring device with protective measures. Summary of the Invention

[0006] In view of the problems in related technologies, the present invention proposes a power monitoring device with a protection device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A power monitoring device with a protection mechanism includes a protective housing, a cover rotatably mounted on the side of the protective housing, a power monitoring box installed inside the protective housing by screws, a shock-absorbing base at the bottom of the protective housing, a rectangular air inlet at the rear of the protective housing, two fans installed inside the rectangular air inlet, a protection mechanism installed on the inner wall of the protective housing above the power monitoring box, and multiple cable inlets at the bottom of the protective housing.

[0009] Preferably, heat dissipation holes are provided on both sides of the protective shell, and a metal dustproof mesh is provided on the inner side of both heat dissipation holes.

[0014] Smoke detectors can be used to monitor smoke and fire in the power monitoring box, while temperature detectors can be used to monitor the temperature of the power monitoring box.

[0015] Preferably, the rectangular box has an opening on the rear side located outside the two fans, and the interior of the rectangular box is provided with a partition that divides the rectangular box into a cooling zone and a foam storage zone. The bottom of the cooling zone is connected to an air blowing valve, and the bottom end of the air blowing valve is provided with an air blowing port.

[0016] Two fans work to send outside air into the cooling zone inside the rectangular box, and the air blowing valve opens to blow air through the air blowing port, thereby achieving the purpose of cooling the power monitoring box.

[0018] By closing the air-blowing valve and opening the connecting valve, airflow enters the interior of the foam storage area through the connecting port, increasing the air pressure inside the foam storage area. This causes the fire extinguishing valve to open, and the foam extinguishing agent is discharged through the fire extinguishing port to extinguish the fire in the power monitoring box, preventing a fire from occurring.

[0019] Preferably, a protective cover is provided on the rear side of the rectangular air inlet, and the bottom of the protective cover is open.

[0020] The protective cover can protect the rectangular air intake from rain and dust.

[0023] Preferably, the diameter of the fire extinguishing port is 20-30mm, and a diffusion nozzle (diffusion angle 60°-90°) is installed at the outlet to ensure that the foam coverage covers the top and sides of the power monitoring box; the cross-sectional area of ​​the connecting port is 1 / 3-1 / 2 of the cross-sectional area of ​​the cooling zone, and the sealing pressure is ≥0.2MPa when the connecting valve is closed to prevent foam leakage into the cooling zone.

[0024] In summary, the technical effects and advantages of this invention are as follows:

[0025] The shock-absorbing base is supported by four rubber pads, which can absorb shocks for the shock-absorbing base and the protective shell. The heat dissipation holes can provide ventilation and heat dissipation. The metal dustproof mesh can prevent dust. The temperature monitor can monitor the temperature of the power monitoring box. Two fans work to send outside air into the cooling zone inside the rectangular box. The air blowing valve opens and blows air through the air blowing port to achieve the purpose of cooling the power monitoring box.

[0026] The smoke detector can monitor smoke and fire in the power monitoring box. By closing the air valve and opening the connecting valve, the airflow enters the interior of the foam storage area through the connecting port, increasing the air pressure inside the foam storage area. The fire extinguishing valve opens, and the foam extinguishing agent is discharged through the fire extinguishing port to extinguish the fire in the power monitoring box and prevent fire. The protective cover can protect the rectangular air inlet from rain and dust.

[0027] This invention uses a temperature monitor to monitor the temperature of the power monitoring box, two fans to send outside air into the cooling zone inside the rectangular box, and an air blowing valve to blow air through the air outlet to cool the power monitoring box. A smoke alarm can monitor the power monitoring box for smoke and fire, and foam extinguishing agent is discharged through the extinguishing port to extinguish the fire in the power monitoring box and prevent fire.
