[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0027] A power quality monitoring device with wind and sand protection, combined with Figure 1 、 Figure 2 , including a cabinet 1, a cabinet door 2, a monitor 3, a slanted roof 4 and a back panel 5. The cabinet door 2 is hinged on the cabinet 1, the monitor 3 is fixedly connected to the cabinet door 2, the slanted roof 4 is fixedly connected to the top of the cabinet 1, the outer diameter of the bottom of the slanted roof 4 is larger than the outer diameter of the cabinet 1, the bottom of the slanted roof 4 is located on one side of the cabinet door 2 for air outlet, and the other side of the bottom of the slanted roof 4 for air intake. The back panel 5 is fixedly connected to the cabinet 1, and a fan is provided on the back panel 5 to make the air outside the cabinet 1 flow from one side of the bottom of the slanted roof 4 to the cabinet 1, and flow out of the cabinet 1 through the other side of the bottom of the slanted roof 4.
[0028] Combine Figure 1 、 Figure 2 The cabinet body 1 is a square shell, the bottom of which is fixed to a concrete base 6 to enhance wind resistance. A long, hinged windshield 11 is attached to the cabinet door 2. The monitor 3 is equipped with control keys 31, which are exposed on the cabinet door 2. The windshield 11 flips downward to cover the control keys 31, reducing erosion by wind and sand. A magnetic head 12 is installed at the bottom of the windshield 11. This magnetic head 12 adheres to the cabinet door 2, reducing the chance of the windshield 11 being lifted by the wind and enhancing its protective performance.
[0029] Combine Figure 1 、 Figure 2The back panel 5 is a square plate, extending vertically along its length to divide the cabinet 1 into two compartments, front and back. Several L-shaped mounting straps 51 are spaced apart on the back panel 5, with openings of the mounting straps 51 facing each other. Electrical components are inserted between the mounting straps 51. The mounting straps 51 are spaced apart with several strip-shaped holes, which are threaded with bolts to secure the electrical components to the back panel 5, facilitating installation and fixation. Several ventilation holes 52 are spaced apart on the back panel 5 to connect the two compartments. A fan is fixed to the mounting straps 51 on the back panel 5 at the ventilation holes 52, allowing the fan to better promote air flow between the two compartments within the cabinet 1, thereby achieving good heat dissipation.
[0030] Combine Figure 4 、 Figure 5 The air inlet of the slanted roof 4 is located at the rear side of the back panel 5, and an air inlet duct 42 is provided at the air inlet. The air inlet duct 42 is connected to the cavity of the cabinet 1 at the rear side of the back panel 5. The air outlet at the top of the slanted roof 4 is located at the front side of the back panel 5. A blocking net 41 is provided at the air outlet of the slanted roof 4. The blocking net 41 is a mesh structure woven from metal wires. Several vertical columns are fixedly connected between the top of the blocking net 41 and the slanted roof 4 to prevent the blocking net 41 from being easily deformed. The air intake is ensured by setting an open-ended air inlet. With the help of the fan, the air can smoothly enter the cabinet 1 to take away the heat generated by the electrical appliances. At the same time, the blocking net 41 is provided to prevent large particles of sand and gravel from entering the cabinet 1 from the air outlet when the external wind and sand are strong, causing damage to the electrical components. An L-shaped air duct 53 is fixedly connected to the ventilation hole 52 on the side of the back panel 5 away from the mounting belt 51, and the open end of the air duct 53 faces downward. By providing the air duct 53, air can flow downward from the upper end, and then upward into the air duct 53 to contact with the electrical components to dissipate heat. At the same time, due to the effect of gravity, large particles of sand and stone will not flow upward into the air duct 53, thereby preventing the sand and stone from impacting and damaging the electrical components in the cabinet 1.
[0031] Combine Figure 2 、 Figure 3 A slanted ramp 54 is fixedly attached to the bottom of the back panel 5. A flap 13 is hingedly connected to the bottom rear side of the cabinet 1. The flap 13 is a long, strip-like structure, its length parallel to the width of the cabinet 1. The top of the flap 13 is hinged to the cabinet 1 and pivots only outward. The bottom end of the ramp 54 connects to the cabinet 1 below the flap 13. The ramp 54 and flap 13 are designed to guide sediment out of the cabinet 1. The one-way flap 13 also prevents air from being drawn into the air duct 53 through the flap 13 and causing sediment to enter.
[0032] To sum up, by setting up the back panel 5 to separate the space of the cabinet 1, and cooperating with the air duct 53 to achieve solid-gas separation, the erosion of sand and stones on the power quality monitoring device in a windy and sandy environment can be reduced, while ensuring good heat dissipation performance. The device has a simple structure and low modification cost, and can be put into use on a large scale.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
