[0001] The present application relates to the technical field of power metering screens, and specifically to a power metering screen. Background Art

[0002] The power metering panel is a device used for statistical calculation and observation of electricity data. The power metering panel is installed with devices such as watt-hour meters. It is mainly used for real-time monitoring and display of electric energy parameters and power quality parameters. It is connected to the power line of the electrical equipment and can collect current, voltage and other signals, and process and calculate them through the internal metering circuit to obtain the power consumption of the electrical equipment. The power metering panel can intuitively display various electric energy parameters, such as current, voltage, etc. through the screen.

[0003] It is necessary to install equipment such as electric meters inside the power metering panel, and the power metering panel will be placed in an outdoor cabinet, so it is very important to have a good heat dissipation effect, especially in the hot summer. However, the existing power metering panels usually have a relatively simple heat dissipation structure, and most of them use passive heat dissipation to achieve the heat dissipation effect, which makes the heat dissipation effect of the overall structure poor when the outside temperature is high, which is not conducive to the circulation and ventilation of the internal air. In this regard, the present application provides a power metering panel to solve the above problems. Utility Model Content

[0009] By adopting the above technical solution, the electrical equipment can be normally installed on the installation plate.

[0010] Furthermore, the distance between the back side of the mounting plate and the inner rear side wall of the main box body is at least one centimeter, and the lifting rings are distributed symmetrically on the left and right.

[0011] By adopting the above technical solution, the back of the installation plate is provided with space for air flow, which is beneficial to improving the heat dissipation effect and facilitates lifting and moving the main box body through the lifting ring.

[0012] Furthermore, the front side of the box door is provided with three connecting holes for three glass screens to pass through and be fixed respectively.

[0013] By adopting the above technical solution, outsiders can view the internal equipment status through the glass screen.

[0014] Furthermore, the mounting member is a rectangular box with an opening at the bottom, and the top of the mounting hole is covered by the mounting member.

[0015] By adopting the above technical solution, the mounting member can block the inside of the mounting hole, so that the air inside can only be discharged under the conveying action of the fan.

[0016] Furthermore, the dust shield is connected to the inner side of the corresponding heat dissipation hole by means of screws, and the two heat dissipation holes are arranged vertically.

[0017] By adopting the above technical solution, the dust shield is easy to disassemble, replace and clean.

[0018] Furthermore, the front holes are distributed above and below the box door, and the number of the inclined baffles is equal to the number of the front holes.

[0019] By adopting the above technical solution, the front hole can also be connected to the outside air.

[0020] Furthermore, the oblique baffle is located on the front side corresponding to the front hole and can block the front side of the front hole.

[0021] By adopting the above technical solution, the inclined baffle can block the falling dust and prevent dust from entering.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The power metering panel, through the coordinated use of the main body components and the heat dissipation components inside the main box, can achieve a good heat dissipation effect while also having a certain dust-proof effect, thereby preventing the entry of dust. Therefore, in summer, the internal heat can be discharged normally by relying on the exhaust ventilation and heat dissipation effect, while preventing external dust from entering the interior and affecting the electrical equipment, thereby greatly improving the heat dissipation capacity and practical performance of the power metering panel.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] See also Figure 1-3 The present application provides a technical solution: an electric power metering screen, comprising a main body box 1, a main body component 200 for installing electric power equipment is installed on the inner side of the main body box 1, and a heat dissipation component 300 for heat dissipation is installed inside the main body box 1; through the coordinated use of the main body component 200 and the heat dissipation component 300 inside the main body box 1, a good heat dissipation effect can be achieved while having a certain dust-proof effect, thereby avoiding the entry of dust. In summer, the internal heat can be discharged normally by relying on the exhaust ventilation and heat dissipation effect, and at the same time, it can prevent external dust from entering the interior and affecting the electrical equipment, thereby greatly improving the heat dissipation capacity and practical performance of the electric power metering screen.

[0030] In this embodiment, the heat dissipation assembly 300 is a structure used to ventilate and dissipate heat inside the box.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the heat dissipation assembly 300 includes a mounting hole 301 opened at the bottom of the main box body 1, a mounting member 302 connected to the inner bottom wall of the main box body 1 by screws and located on the outside of the top of the mounting hole 301, two fans 303 passing through and fixed on the top of the mounting member 302, two heat dissipation holes 304 opened on the side of the main box body 1, a dust shield 305 detachably installed on the inner side of the heat dissipation hole 304, a plurality of front holes 306 opened on the front of the main box body 1, and a plurality of inclined baffles 307 fixed to the front of the main box body 1.

[0032] It should be noted that the mounting member 302 is a rectangular box with an opening at the bottom, and the top of the mounting hole 301 is covered by the mounting member 302, so that the mounting member 302 can block the interior of the mounting hole 301, so that the internal air can only be discharged under the conveying action of the fan 303.

[0033] In addition, the dust shield plate 305 is connected to the inner side of the corresponding heat dissipation hole 304 by means of screws, and the two heat dissipation holes 304 are arranged in an upper and lower arrangement, so that the dust shield plate 305 is easy to disassemble, replace and clean. At the same time, the dust shield plate 305 can also be connected by snapping, using the elastic snap-fit ​​limit between metal or plastic parts to achieve the function of convenient installation and disassembly.

[0034] In this embodiment, the main body assembly 200 is a structure for providing an installation environment for electrical equipment.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the main body component 200 includes a plurality of mounting frames 201 connected to the inner side of the main box body 1 by screws, a mounting plate 202 connected to the other side of the mounting frame 201 by screws and on which the power supply device is installed, two lifting rings 203 fixed to the top of the main box body 1, a box door 204 hinged to the front side of the main box body 1 by hinges, and three glass screens 205 fixedly installed on the front side of the box door 204.

[0036] It should be noted that the distance between the back side of the mounting plate 202 and the inner rear side wall of the main box body 1 is at least one centimeter. Specifically, the distance between the back side of the mounting plate 202 and the inner rear side wall of the main box body 1 is two and a half centimeters, so that the back side of the mounting plate 202 has space for air flow, which is beneficial to improving the heat dissipation effect. The lifting rings 203 are distributed symmetrically on the left and right, which makes it easy to lift and move the main box body 1 through the lifting rings 203.

[0037] In addition, three connecting holes are provided on the front of the box door 204 for three glass screens 205 to penetrate and be fixed respectively, so that outsiders can check the internal equipment status through the glass screens 205. The front holes 306 are distributed above and below the box door 204. The number of inclined baffles 307 is equal to the number of front holes 306. The inclined baffles 307 are located on the front side of the corresponding front holes 306 and can block the front of the front holes 306, so that the front holes 306 also have the ability to connect to the outside air. At the same time, under the action of the inclined baffles 307, the falling dust can be blocked to prevent dust from entering.

[0038] The working principle of the above embodiment is:

[0039] When in use, start the fan 303, so that the hot air inside the main box 1 is driven by the fan 303 and discharged to the outside through the installation hole 301. At the same time, the outside air is filtered by the dust shield 305 and then enters the inside of the main box 1 through the heat dissipation hole 304 to achieve air exchange. The electrical equipment will release heat when in use, so that the temperature inside the main box 1 is much higher than the outside air temperature. Through the circulation and exchange of air, the hot air inside the main box 1 can be discharged, and the air with a lower outside temperature will enter the inside of the main box 1, so that the air inside the main box 1 can be reduced, which can achieve the effect of heat dissipation.

[0040] Compared with the prior art, the power metering panel, through the coordinated use of the main body component 200 and the heat dissipation component 300 inside the main box body 1, can achieve good heat dissipation effect while also having a certain dust-proof effect, thereby avoiding the entry of dust. Therefore, in summer, the internal hot air can be discharged normally by relying on the exhaust ventilation and heat dissipation effect, while preventing external dust from entering the interior and affecting the electrical equipment, thereby greatly improving the heat dissipation capacity and practical performance of the power metering panel, and solving the shortcoming of poor passive heat dissipation effect of the existing power metering panel in summer.

[0041] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
