Description

Technical Field

[0001] This application relates to the field of electric energy metering, and particularly to an integrated pre-payment electricity consumption and protection management terminal. Background Art

[0002] With the rapid development of China's economy, the demand for electricity in all walks of life is increasing, and the phenomenon of uneven electricity consumption at different times is becoming increasingly serious. To alleviate the increasingly sharp contradiction between power supply and demand in China, adjust the load curve, improve the uneven electricity consumption phenomenon, implement the peak, flat, and valley time-of-use electricity price system across the country, "cut peak and fill valley", improve the national electricity consumption efficiency, and rationally utilize electric power resources, the power departments in some provinces and cities in China have begun to gradually introduce multi-rate electricity meters to charge users' electricity consumption by time; electricity meters are widely used in the work of electric energy metering and billing. The pre-payment electricity meter is one of many types of electricity meters. In addition to the metering function of ordinary electricity meters, particularly, users need to buy electricity first and can use electricity only after buying electricity. If the user does not continue to buy electricity after using up the electricity, the power supply will be automatically cut off; at present, with the popularization of new energy electric vehicles, the use of charging piles is becoming more and more frequent. In some enterprises, charging piles usually adopt a pre-payment method for employees to use;

[0003] Referring to the Chinese patent application with the publication number CN214504518U, a combined user pre-payment electricity meter is disclosed, which includes a pre-payment electricity meter and a CIU user terminal. The CIU user terminal is connected in parallel to the line between the pre-payment electricity meter and the user load. The data communication between the CIU user terminal and the pre-payment electricity meter is based on LoRa wireless transmission. The power data and electricity bill recharge can be queried through the CIU user terminal, which has the advantages of low cost and convenient query and recharge;

[0004] However, in the prior art, the protection management terminal is usually installed in the underground garage or parking lot. During the cleaning of the ground or in rainy and humid weather, dust and water vapor will enter the shell of the protection management terminal through the heat dissipation openings of the shell. The dust and humid water vapor accumulated on the working elements or connecting wires in the shell are likely to cause the phenomenon of pollution conduction and lead to a fire; for this reason, we have designed an integrated pre-payment electricity consumption and protection management terminal.

[0036] Based on this, in order to improve the problem in the related art that when the floor is being cleaned or in rainy and humid weather, dust and water vapor will enter the shell through the heat dissipation port of the shell of the protection management terminal, and the dust and humid water vapor accumulated on the working components or connecting wires in the shell can easily cause the phenomenon of dirt accumulation and conduction, resulting in a fire, the embodiment of the present application provides the following solution.

[0037] See also Figures 1 to 6, The integrated prepaid electricity and protection management terminal includes: an installation housing 1, an outer housing 2, a filtering mechanism, and a working mechanism. A plurality of installation studs 11 and a plurality of installation screw holes 21 are respectively provided on the installation housing 1 and the outer housing 2. Screws are provided between the installation studs 11 and the installation screw holes 21. A plurality of bent heat dissipation holes 13 are formed on the side wall of the installation housing 1. A fixing groove 15 is provided on the inner wall of the installation housing 1. The notch of the fixing groove 15 is arranged at one end of the fixing groove 15 close to the plurality of bent heat dissipation holes 13. A through port is opened at one end of the fixing groove 15 away from the bent heat dissipation holes 13; A plurality of mounting pieces 14 are provided on the side wall of the installation housing 1. An adsorption rubber strip 12 is provided between the installation housing 1 and the outer housing 2;

[0038] When installing this protection management terminal, the installation housing 1 is installed at the place to be used through installation bolts and the mounting pieces 14. An adsorption rubber strip 12 is provided at the connection inside the installation housing 1 and the outer housing 2. One end of the adsorption rubber strip 12 is fixedly connected to the inner wall of the installation housing 1, and the other end is automatically adsorbed after the installation housing 1 and the outer housing 2 are clamped and installed, preventing dust and water vapor from entering the installation housing 1 through the gap at the connection between the installation housing 1 and the outer housing 2, so as to ensure the normal operation of the working components and connecting wires inside the installation housing 1.

[0039] Please refer to Figure 3 and Figure 4 , The filtering mechanism includes a moisture-absorbing cotton 42 for preventing dust and water vapor entering the installation housing 1 from causing dirt accumulation and conduction, which may lead to a fire; The filtering mechanism also includes: an installation box 4, a dust-proof filter cotton 41, a first heat-conducting plate 44, and a second heat-conducting plate 45. An installation groove 16 is formed on the installation housing 1. The installation box 4 is arranged in the fixing groove 15. A lifting groove 43 is provided at one end of the installation box 4 close to the installation groove 16. The dust-proof filter cotton 41 is arranged at one end of the installation box 4 close to the bent heat dissipation holes 13, and the moisture-absorbing cotton 42 is arranged at one end of the installation box 4 away from the bent heat dissipation holes 13;

[0040] With such a setting, when the outside air enters the fixing groove 15 through the bent heat dissipation holes 13, and one end of the installation box 4 close to the bent heat dissipation holes 13 is provided with through holes, and the other end is provided with a grille, and the grille is located above the through holes, and the same through port is also provided at one end of the fixing groove 15 away from the bent heat dissipation holes 13, then the air entering the fixing groove 15 is filtered and intercepted by the dust-proof filter cotton 41 and the moisture-absorbing cotton 42, preventing dust and water vapor from entering the installation housing 1 through the bent heat dissipation holes 13, and avoiding the occurrence of a fire caused by the phenomenon of dirt accumulation and conduction of the working components or connecting wires inside the installation housing 1 due to the accumulated dust and humid water vapor;

[0041] The first heat-conducting plate 44 is arranged at one end of the fixing groove 15 away from the bent heat dissipation holes 13, and the second heat-conducting plate 45 is arranged at one end of the installation box 4 away from the bent heat dissipation holes 13;

[0042] The effect of such a setting is that the heat generated by the normal operation of the working components and the connecting wires in the installation housing 1 is transmitted to the moisture-absorbing cotton 42 through the first heat-conducting plate 44 and the second heat-conducting plate 45, which facilitates the easier overflow of water vapor through the bent heat-dissipating holes 13 outside the installation housing 1. Here, since the flow ventilation duct entering the installation housing 1 is arranged from low to high, the entry of water vapor into the installation housing 1 is greatly reduced, and the structure of the bent heat-dissipating holes 13 also greatly reduces the entry of dust into the installation housing 1.

[0043] Please refer to Figure 3 and Figure 4 , the working mechanism includes a watt-hour meter 33 for providing power consumption services to users in a prepaid manner; the working mechanism further includes: a circuit breaker 3, a lightning protection and surge protection component 31, and a set of housing mounting seats 32. The set of housing mounting seats 32 is arranged in the installation housing 1, and the outer cover housing 2 is provided with a set of conductive connection pieces 22 corresponding to the position of the set of housing mounting seats 32. The housing mounting seats 32 are electrically connected to the watt-hour meter 33 through the conductive connection pieces 22; both the circuit breaker 3 and the lightning protection and surge protection component 31 are arranged in the installation housing 1, and both the circuit breaker 3 and the lightning protection and surge protection component 31 are electrically connected to the set of housing mounting seats 32;

[0044] By electrically connecting the circuit breaker 3 and the lightning protection and surge protection component 31 to the set of housing mounting seats 32, when a sudden peak current or voltage occurs in the circuit due to the outside, the lightning protection and surge protection component 31 can conduct and shunt in an extremely short time, thereby avoiding damage to the working components in the circuit caused by surges.

[0045] Please refer to Figure 1 and Figure 2 , the outer cover housing 2 is provided with installation card holes corresponding to the position of the circuit breaker 3, and one end of the circuit breaker 3 away from the installation housing 1 is clamped in the installation card holes. A sealing strip is provided on the clamping surface of the installation card holes and the circuit breaker 3.

[0046] Please refer to Figures 3 to 6 , a disassembly plate 46 is provided on the installation groove 16, and installation holes are provided on both the disassembly plate 46 and the installation groove 16, and screws are provided in the installation holes;

[0047] The effect of such a setting is that by providing a fixing groove 15 in the installation housing 1, the installation box 4 containing the dust-proof filter cotton 41 and the moisture-absorbing cotton 42 is placed, and the installation box 4 containing the dust-proof filter cotton 41 and the moisture-absorbing cotton 42 is inserted into the fixing groove 15. Finally, the installation box 4 is fixed in the fixing groove 15 through screws and the disassembly plate 46. By regularly opening the installation box 4, it is convenient to replace the dust-proof filter cotton 41 and the moisture-absorbing cotton 42, and the operation is simple and convenient.

[0048] As can be seen from the above, the working principle of this application is as follows:

[0049] When the outside air enters the fixing groove 15 through the bent heat dissipation hole 13, and one end of the installation box 4 close to the bent heat dissipation hole 13 is provided with a through hole, and the other end is provided with a grille, and the grille is located above the through hole. Similarly, a through port is also provided at the end of the fixing groove 15 away from the bent heat dissipation hole 13. After the air entering the fixing groove 15 is filtered and intercepted by the dust-proof filter cotton 41 and the moisture-absorbing cotton 42, it is avoided that dust and water vapor enter the installation shell 1 through the bent heat dissipation hole 13;

[0050] The heat generated by the working components and connecting wires in the installation shell 1 during normal operation is transmitted to the moisture-absorbing cotton 42 through the first heat conduction plate 44 and the second heat conduction plate 45, which facilitates the water vapor to overflow from the installation shell 1 through the bent heat dissipation hole 13 more easily. Here, since the flow ventilation duct entering the installation shell 1 is arranged from low to high, the entry of water vapor into the installation shell 1 is greatly reduced, and the structure of the bent heat dissipation hole 13 itself also greatly reduces the entry of dust into the installation shell 1.

[0051] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
