Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation equipment for power monitoring motherboards, and more specifically, to a waterproof component for power monitoring motherboards. Background Technology

[0002] Common power monitoring systems utilize computer technology, communication technology, and automation technology to monitor, control, and manage power systems such as transformers in real time. Their core functions include data acquisition, operation monitoring, operation control, fault diagnosis, and optimized scheduling. In this process, the monitoring host is an indispensable device. The motherboard within the power control host is a crucial component that connects various peripheral sensors (such as contact ultrasonic sensors and high-frequency current sensors used in transformer monitoring) as well as encapsulated and inserted electronic components such as controllers, memory, and network modules.

[0003] To connect a large number of sensors, existing monitoring hosts typically have three motherboards inside their casing. The top and bottom motherboards are used to expand sensor interfaces, while the middle motherboard is used to install the main electronic components such as controllers, memory, and network modules. In actual use, existing monitoring hosts only use the front cover plate for bolted connection and waterproofing, which is not effective enough. At the same time, there is no special waterproof structure designed for the interface boards of the multiple motherboards at the rear, resulting in poor waterproofing performance and easy water ingress and damage to internal electronic components. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof component for a power monitoring motherboard. This waterproof component provides waterproof protection for the external and internal three motherboards of the power monitoring host, as well as the rear interface board, thereby protecting the main electronic components on the motherboard and improving the working stability of the power monitoring motherboard.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A waterproof power monitoring motherboard assembly includes a front and rear perforated power monitoring housing, a front cover, and a rear cover. Inside the power monitoring housing, three motherboards are sequentially clamped from top to bottom by symmetrical clamping plates on both sides. The upper and lower ends of both sides of the power monitoring housing, front cover, and rear cover are provided with threaded connecting seats that are aligned front to back and fixed together by bolts. A front waterproof frame is embedded inside the front cover. The rear side of the front waterproof frame is provided with a surrounding waterproof sealing strip. Positioning top blocks are provided inwardly at the four corners of the front waterproof frame on its front side, and these positioning top blocks are pressed against the inner side of the front cover. The upper and lower ends of the front waterproof frame are provided with transverse support plates, and a waterproof diaphragm is fixed between the upper and lower support plates, covering the display motherboard area inside the front cover.

[0007] As a further optimization of this solution, a rear waterproof frame is embedded in the front of the power monitoring housing. The front side of the rear waterproof frame is machined with a circumferential groove. A waterproof sealing strip is embedded in the groove. The inner side of the rear waterproof frame is provided with concave plates at the corresponding positions of the clamping plate. The concave plates are aligned and snapped onto the front side of the clamping plate. Each concave plate has a bracket on the inner side of the rear waterproof frame at the upper end. An oblique waterproof diaphragm is bonded and fixed between the bracket and the concave plate.

[0008] As a further optimization of this solution, the surface of the rear cover is machined with three L-shaped wiring channels with decreasing lengths from top to bottom. The front end of the horizontal section of the upper and lower L-shaped wiring channels corresponds to the sensor interface board position of the upper and lower motherboards, and the front end of the horizontal section of the middle L-shaped wiring channel corresponds to the I / O interface board position of the middle motherboard. The vertical sections of the three L-shaped wiring channels are all set to open downwards.

[0009] As a further optimization of this solution, the rear side of the power monitoring housing is provided with a surrounding waterproof sealing strip, and the front side of the rear cover is machined with a surrounding groove and embedded in the waterproof sealing strip on the rear side of the power monitoring housing.

[0010] As a further optimization of this solution, the sensor lines, power lines and data lines pass through the three L-shaped wiring channels.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This utility model designs a power monitoring housing, a front cover, and a rear cover structure. Waterproof sealing strips on the front cover and the rear of the power monitoring housing are embedded in slots on the front and rear sides of the housing, respectively. Combined with external bolt connections, this achieves waterproofing of the power monitoring housing's exterior. Simultaneously, a waterproof membrane structure covering the display motherboard area and the front areas of the three motherboards further waterproofs the motherboards inside the housing. Three L-shaped wiring channels on the rear cover guide the wiring of the sensor interface boards on the upper and lower motherboards, as well as the I / O interface boards on the middle motherboard, allowing the wiring to run downwards. This waterproofing of the motherboard interface boards protects the main electronic components on the motherboard, improving the stability of the power monitoring motherboard.
