Description

Technical Field

[0001] The utility model relates to the technical field of electric power meters with waterproof mechanisms, in particular to an electric power meter with waterproof mechanisms. Background Art

[0002] Power meters are instruments and equipment used to monitor, detect, test, detect, detect, measure, observe, calculate, and process various physical quantities, material components, and physical parameters of power equipment or power equipment in various hydropower, wind power, thermal power, nuclear power, new energy, and power generation, transmission, substation, and distribution power plants. Power meters have multiple functions, such as power measurement, load monitoring, power quality parameter monitoring and analysis, power energy statistics, over-limit alarms, maximum value records, and event sequence records. In applications, power meters can provide detailed power consumption data for residential areas, commercial buildings, and public facilities, helping them understand power consumption and take corresponding energy-saving measures. Power meters are often installed outdoors, so the waterproof function of power meters is particularly important.

[0003] An electric power meter with a waterproof mechanism is disclosed in the publication number CN218938341U. Although the utility model provides a waterproof insulating shell, an insulating thermally conductive strip and a waterproof thermally conductive shell, and seals the contact surfaces of the waterproof insulating shell and the waterproof thermally conductive shell, and the insulating thermally conductive strip and the waterproof insulating shell during use, multiple waterproof structures are provided for the electric power meter, so that the electric power meter has a good waterproof function. At the same time, the insulating thermally conductive strip conducts heat absorbed by the waterproof thermally conductive shell from the electric power meter. The heat dissipation design on four sides enables the electric power meter to achieve sufficient heat dissipation effect.

[0004] However, the electric meter with waterproof mechanism has the following disadvantages: the sealing effect of the structure is strong, and the disassembly and assembly are relatively stable. If the internal circuit is abnormal, it is difficult to repair, and the waterproof structure on the shell surface may need to be replaced as a whole, which is not conducive to cost saving.

[0030] Example 1

[0031] Reference Figure 1-5 , which is the first embodiment of the utility model, provides an electric meter with a waterproof mechanism, the structure comprising:

[0032] The packaging unit 100 includes a cover plate 101, and a display screen 102 is mounted on the cover plate 101, through which various power parameters can be intuitively displayed;

[0033] The mounting assembly 200 includes a small limiting block 201, a large limiting block 202 and a connecting block 203. The small limiting block 201 is fixedly connected to the back of the cover plate 101. The large limiting block 202 and the small limiting block 201 are detachably connected through the connecting block 203. The cover plate 101 and the housing 301 can be quickly disassembled and assembled through the mounting assembly 200. The polymer anti-oxidation material used in the mounting assembly 200 can effectively resist oxidation, thereby extending the service life of the polymer material;

[0034] The shell unit 300 includes a shell 301, a circuit board 302, a rubber pad 303 and a sealing ring 304. The shell 301 is detachably connected to the packaging unit 100 through the installation component 200. The circuit board 302 is installed inside the shell 301. The rubber pad 303 is fixedly connected to the corner inside the shell 301. The sealing ring 304 is fixedly connected to the edge of the shell 301. The shell 301 protects the internal circuit board 302, and the sealing ring 304 is close to the cover plate 101 to increase the sealing effect. The corners of the circuit board 302 are wrapped by the rubber pad 303, which can effectively reduce the impact force generated by the device on the circuit board 302 when it is hit, and play a shock-absorbing and buffering role for the circuit board 302.

[0035] Furthermore, a rectangular groove is formed on the edge of the shell 301 , and the large limiting block 202 is fixedly connected in the rectangular groove, so that the large limiting block 202 is fixed to the shell 301 through the rectangular groove.

[0036] Furthermore, the inner wall of the small limit block 201 is fixedly connected with the A block 2011, and the inner wall of the large limit block 202 is fixedly connected with the B block 2021. When the V-block 2031 passes through the A block 2011 and the B block 2021, the rear end of the V-block 2031 will be stretched and pressed against the A block 2011 and the B block 2021 to achieve installation.

[0037] Furthermore, the connecting block 203 includes a V-shaped block 2031 and a fixing plate 2032 . The V-shaped block 2031 is fixedly connected to both ends of the fixing plate 2032 . The two V-shaped blocks 2031 are connected via the fixing plate 2032 to achieve connection between the small limiting block 201 and the large limiting block 202 .

[0038] Furthermore, a waterproof coating is sprayed on the shell 301, and a drainage groove 3011 is also opened on the shell 301. The waterproof coating is made of silicone rubber coating, which can prevent water and moisture from invading. The inner bottom wall of the drainage groove 3011 is sloped, which facilitates rainwater to slide down the drainage groove 3011 and prevents rainwater from gathering on the shell 301.

[0039] Furthermore, a groove is provided on the side of the shell 301, and a heat sink 3012 is fixedly installed in the groove. The heat sink 3012 facilitates the diffusion of heat generated during the operation of the internal circuit board 302, thereby preventing the circuit board 302 from being burned due to excessive temperature.

[0040] During use, the circuit board 302 is first installed in the shell 301. The corners of the circuit board 302 are wrapped with rubber pads 303, which can effectively reduce the impact force on the circuit board 302 when the device is hit, and play a shock-absorbing and buffering role for the circuit board 302. The shell 301 prevents water and moisture from invading through the silicone rubber coating on the surface. The inner bottom wall of the drainage groove 3011 is sloped, which facilitates rainwater to slide down the drainage groove 3011 and prevents rainwater from gathering on the shell 301. The heat generated during the operation of the internal circuit board 302 is then dispersed through the heat sink 3012 to prevent the circuit board 302 from being burned out due to excessive temperature.

[0041] Finally, the small limit block 201 and the large limit block 202 are fixedly connected to the cover plate 101 and the shell 301 respectively, and the connecting block 203 is inserted into the small limit block 201 and the large limit block 202. When the V-shaped block 2031 passes through the A block 2011 and the B block 2021, the rear end of the V-shaped block 2031 will be stretched and pressed against the A block 2011 and the B block 2021. At this time, the sealing ring 304 is in close contact with the cover plate 101 to increase its sealing performance and achieve quick installation. When disassembly is required, the cover plate 101 is moved to the right, and the V-shaped block 2031 in the large limit block 202 is not blocked by the B block 2021 and can be taken out, thereby facilitating the maintenance of the internal circuit board 302 and the replacement of the connecting block 203. The polymer antioxidant material adopted by the installation component 200 can effectively resist oxidation, thereby extending the service life of the polymer material.

[0042] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
