[0036] Combine the following Figure 1-Figure 8 The invention describes a rapidly installable electricity metering device for short-term green electricity trading.

[0037] like Figure 1-Figure 8 As shown, in one embodiment, a rapidly installable electricity metering device for short-term green electricity trading comprises:

[0038] The bottom plate 120 has a back plate 110 fixedly connected to one side of the bottom plate 120. A mounting frame is formed between the back plate 110 and the bottom plate 120. The surface of the mounting frame is provided with an electric power meter 100.

[0039] The power meter 100, the back plate 110, the bottom plate 120, the connecting plate 130 and the connector 140, wherein the bottom plate 120 is arranged on one side of the back plate 110, and a mounting frame is formed between the back plate 110 and the bottom plate 120, and the surface of the bottom plate 120 is provided with evenly distributed through holes, and the through holes correspond to the interfaces of the power meter 100, and the bottom of the bottom plate 120 is provided with a connecting plate 130, and the top of the connecting plate 130 is provided with a connector 140 matching the interface of the power meter 100;

[0040] A mounting structure 200, wherein the mounting structure 200 is disposed inside the mounting frame;

[0041] The mounting structure 200 includes an auxiliary component 210 and a positioning component 220. The auxiliary component 210 is disposed inside the bottom plate 120, and the positioning component 220 is disposed on the surface of the back plate 110.

[0042] Among them, the auxiliary component 210 includes a connecting through hole 2101 opened inside the base plate 120, and a semiconductor cooling plate 2113 is embedded and installed on the top of the base plate 120, and the cold surface of the semiconductor cooling plate 2113 is flush with the top surface of the base plate 120, and the hot surface of the semiconductor cooling plate 2113 is provided with a heat-conducting rod 2114, and one end of the heat-conducting rod 2114 is in contact with the hot surface of the semiconductor cooling plate 2113.

[0043] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, a connecting ring 2103 is fixedly connected to the inner wall of the connecting through hole 2101, a sealing plate 2105 is provided on the side of the connecting ring 2103 away from the back plate 110, the diameter of the sealing plate 2105 is larger than the inner diameter of the connecting ring 2103, and a trigger rod 2104 slidably connected to the inner side of the connecting ring 2103 is fixedly connected to the surface of the sealing plate 2105, and a groove is provided on the surface of the trigger rod 2104.

[0044] A third spring 2106 is fixedly connected to the surface of the sealing plate 2105 , and the other end of the third spring 2106 is fixedly connected to the inner wall of the connecting ring 2103 .

[0045] The inner wall of the connecting through hole 2101 is fixedly connected with a first one-way valve 2102 located on a side of the connecting ring 2103 close to the sealing plate 2105 .

[0046] A connecting cavity 2107 is provided inside the back plate 110, and a guide hole 2112 connected to the connecting through hole 2101 is provided at the lower end of the inner wall of the connecting cavity 2107. A guide channel 2110 is provided inside the connecting cavity 2107, and the cross-sectional shape of the guide channel 2110 is an inverted "L" shape. One end of the guide channel 2110 is connected to the connecting cavity 2107, and a second one-way valve 2109 is provided at the connection point of the guide channel 2110 near the connecting cavity 2107. The inner wall of the guide channel 2110 is provided with connecting holes 2111 that are evenly distributed and connected to the outside.

[0047] Under the action of the semiconductor refrigeration plate 2113, the power meter 100 can be cooled and dissipated to reduce the situation where the power meter 100 measures a large amount of electricity during short-term green electricity transactions and is damaged by overheating. At the same time, the heat energy generated by the hot surface of the semiconductor refrigeration plate 2113 is transferred to the inside of the connecting hole 2101 through the heat-conducting rod 2114, and the connecting ring 2103 and the sealing plate 2105 cooperate with each other to separate the connecting hole 2101 into two sections, and one section is affected by the heat transfer of the heat-conducting rod 2114 and the internal air is heated. As the air is heated and pressurized, the air pressure in the other section is lower than the internal air pressure of the section with the heat-conducting rod 2114, so that the trigger rod 2104 is pushed under the action of pressure to drive the sealing plate 2105 away from the connecting ring 2103 and stretch the third spring 2106. At this time, the side with greater pressure after heating Air can be introduced into the interior of the connecting through hole 2101 on the side with lower pressure through the groove, and discharged through the first one-way valve 2102. Since the pressure on both sides is balanced after the air on the side with higher pressure is discharged, the sealing plate 2105 and the trigger rod 2104 can be driven to reset and re-seal the connecting ring 2103 under the action of the third spring 2106. At this time, the air inside the heat-conducting rod 2114 is lower than the pressure of the external air pressure due to the discharge, so the external air pressure can be introduced into the interior of the connecting through hole 2101 through the connecting hole 2111, the guide channel 2110, the second one-way valve 2109, the connecting cavity 2107 and the guide hole 2112, thereby accelerating the air circulation on both sides of the power meter 100, so that the heat dissipated on both sides can be driven to dissipate together during the air flow process, thereby reducing the heat accumulation on both sides of the power meter 100.

[0048] The first one-way valve 2102 and the second one-way valve 2109 are both relatively mature components in the application of existing technologies. Specifically, the first one-way valve 2102 can allow the air inside the connecting hole 2101 to pass through in one direction and be discharged to the outside, and the second one-way valve 2109 can allow external gas to enter the interior of the connecting cavity 2107 in one direction.

[0049] like Figure 1-Figure 4As shown, the positioning assembly 220 includes two mounting plates 2201 respectively fixedly connected to both sides of the back plate 110, one side of the mounting plate 2201 is provided with a uniformly distributed shell 2202, the shell 2202 is arranged in a conical shape, one end of the shell 2202 passes through the mounting plate 2201 and is flush with the other side of the mounting plate 2201, the other end of the shell 2202 is connected to a connecting sleeve 2208, the inner wall of the shell 2202 is fixedly connected with a fixing ring 2205, the inner wall of the fixing ring 2205 is fixedly connected with an adjusting piece 2206, the adjusting piece 2206 is a rubber material component, the surface of the adjusting piece 2206 is fixedly connected with a connecting rod 2207, the other end of the connecting rod 2207 passes through the connecting sleeve 2208, ventilation grooves are opened on the opposite sides of the two mounting plates 2201, and the inner wall of the ventilation grooves is fixedly connected with a filter 2108.

[0050] A storage cavity is provided on the surface of the connecting rod 2207 , and the inner wall of the storage cavity is fixedly connected to a limit block 2210 . The inner wall of the limit block 2210 is fixedly connected to a second spring 2211 , and the other end of the second spring 2211 is fixedly connected to the inner wall of the connecting rod 2207 .

[0051] A pull plate 2203 is provided on one side of the mounting plate 2201, one end of the connecting rod 2207 is fixedly connected to the surface of the pull plate 2203, a slide plate 2204 is slidably connected to the surface of the pull plate 2203, a mounting rod 2209 is fixedly connected to the surface of the slide plate 2204, and the other end of the mounting rod 2209 passes through the connecting rod 2207 and is fixedly connected to the surface of the limit block 2210.

[0052] When the mounting plate 2201 fits the mounting plane, the pulling plate 2203 can be pulled to drive the connecting rod 2207 to slide out from the inside of the connecting sleeve 2208. During the movement of the connecting rod 2207, the adjusting plate 2206 can be pulled to move synchronously, so that the adjusting plate 2206 is deformed to increase the space between it and the mounting plane to form a negative pressure, and then the fixing effect of the mounting frame is enhanced under the action of the external air pressure difference, which facilitates the installation and placement of the power meter 100. During this process, after the limit block 2210 slides out of the connecting sleeve 2208, the limit block 2210 can be driven to slide out from the inside of the storage groove under the action of the second spring 2211, thereby preventing the connecting rod 2207 from being reinserted into the inside of the connecting sleeve 2208, maintaining a good positioning effect, and when disassembly is required, only the slide plate 2204 is pulled to drive the mounting rod 2209 to shrink the limit block 2210 to the inside of the storage groove to contact the limit.

[0053] At the same time, the provision of the auxiliary component 210 reduces heat accumulation on both sides of the mounting plate 2201, thereby avoiding the situation in which the heat causes a decrease in air pressure in an open environment, resulting in unstable adsorption.

[0054] like Figure 5 and Figure 8 As shown, the inner wall of the through hole is provided with two installation grooves, the inner wall of the installation groove is slidably connected with a resistance increasing block 1401, one side of the resistance increasing block 1401 is fixedly connected with two fixing plates 1402, a rotating rod 1403 is rotatably connected between the two fixing plates 1402, and a spring 1404 is fixedly connected between the end of the rotating rod 1403 and the inner wall of the fixing plate 1402.

[0055] The surface of the rotating rod 1403 is fixedly connected to a mounting block 1405, the other end of the mounting block 1405 is fixedly connected to an adjusting rod 1406, the other end of the adjusting rod 1406 passes through the storage slot and is fixedly connected to a slider 1408 that is slidably connected to the inner wall of the bottom plate 120, and a first spring 1407 is fixedly connected between the surface of the slider 1408 and the inner wall of the bottom plate 120.

[0056] After the power meter 100 is mounted on the mounting frame, the external wire is connected to the connector 140 on the connecting plate 130 and then inserted into the corresponding through hole and then inserted into the interface matching the power meter 100. During this process, the resistance increasing block 1401 can be pushed to shrink into the storage groove, and the friction between the resistance increasing block 1401 and the connector 140 is increased to reduce the possibility of falling off. The setting of the spring 1404 can make the connector 140 always tilt and squeeze the resistance increasing block 1401, thereby improving the clamping and limiting effect.

[0057] Working principle: During the use of the power meter 100, the semiconductor cooling plate 2113 can be activated to dissipate heat and cool the power meter 100, thereby reducing the situation in which the power meter 100 measures a large amount of electricity during short-term green electricity trading and causes overheating and damage. At the same time, the heat energy generated by the hot surface of the semiconductor cooling plate 2113 is transferred to the inside of the connecting through hole 2101 through the heat conducting rod 2114. Under the joint action of the sealing plate 2105 and the connecting ring 2103, the air on the side with higher pressure after heating can be introduced into the inside of the connecting through hole 2101 on the side with lower pressure through the groove, and discharged through the first one-way valve 2102. In addition, due to the exhaust of the air on the side with higher pressure, After the pressure on both sides is balanced, the sealing plate 2105 and the trigger rod 2104 can be driven to reset and re-seal the connecting ring 2103 under the action of the third spring 2106. At this time, the air inside the heat-conducting rod 2114 is lower than the external air pressure due to the exhaust, so that the external air pressure can be introduced into the interior of the connecting through hole 2101 through the connecting hole 2111, the guide channel 2110, the second one-way valve 2109, the connecting cavity 2107 and the guide hole 2112, thereby accelerating the air circulation on both sides of the power meter 100, so that the heat dissipated on both sides can be driven to dissipate together during the air flow process, thereby reducing the heat accumulation on both sides of the power meter 100.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
