[0022] One or more embodiments of this specification provide a power marketing metering and collection device, such as Figures 1 to 4As shown, it includes a box body 101 and a box door 102. A plurality of meters 103 are vertically distributed from top to bottom inside the box body 101. A plurality of contact plates 208 are connected to the upper and lower sides of the meters 103. The contact plates 208 are connected to a conductive transmission cylinder 201. The conductive transmission cylinder 201 is fixedly connected to an insulating cylinder 202. A conductive line 203 is embedded on the insulating cylinder 202. A diode 204 is connected in series on the conductive line 203. One end of the conductive line 203 is connected to the conductive transmission cylinder 201, and the other end is connected to a series circuit 205. The diode 204 allows the current on one side of the conductive transmission cylinder 201 to enter the series circuit 205, and prevents the current on one side of the series circuit 205 from entering the conductive transmission cylinder 201. The series circuit 205 connects all the conductive lines 203 in parallel from top to bottom. A guide plate 206 is installed in the box 101. A monitoring plate 304 that can move up and down along the series circuit 205 is installed in the guide plate 206. An electroscope 305 is installed on the monitoring plate 304. The electroscope 305 contacts the series circuit 205 and is electrically connected at the contact point. The series circuit 205 includes a switch circuit installed between two adjacent groups of insulating cylinders 202. Vertical plates 306 are also installed on the upper and lower surfaces of the monitoring plate 304, respectively. A toggle assembly is installed on the vertical plate 306, which is used to disconnect the switch circuits at the upper and lower ends of the insulating cylinder 202 when the electroscope 305 moves to a certain insulating cylinder 202; The monitoring board 304 is originally located at the end of the series circuit 205. The electroscope 305 is used to monitor whether there is current in the series circuit 205. A control module is installed in the box 101. The control module is used to drive the monitoring board 304 to move to the other end of the series circuit 205 when the electroscope 305 detects that there is current in the series circuit 205, and record the meter 103 number corresponding to the current measured by the electroscope 305 during this process.

[0023] When measuring electric energy, when a meter 103 has leakage, the current is transmitted to the conductive transmission cylinder 201 through the contact plate 208, and then transmitted to the conductive line 203 through the conductive transmission cylinder 201, and then flows through the conductive line 203 through the diode 204 to the series circuit 205, and is monitored by the electroscope 305 located at the original position. At this time, since each conductive line 203 is provided with a diode 204, the leakage between the meters 103 will not be transmitted to each other. After the electroscope 305 detects the current, the control module controls the monitoring board 304 to move toward the other end of the series circuit 205. During the movement, the electroscope 305 reaches When a certain insulating cylinder 202 is detected, the tester 305 contacts the series circuit 205 on the insulating cylinder 202. At this time, the toggle components located on the upper and lower surfaces of the monitoring board 304 disconnect the switch circuits above and below the insulating cylinder 202, so that the test result of the tester 305 is the current charging condition of the insulating cylinder 202. If it is charged, the control module determines the corresponding meter 103 according to the position of the monitoring board 304, and determines which meter 103 is leaking. Otherwise, repeat the above steps. After determining that a leakage occurs, a secondary check can be performed on the specific leakage equipment to avoid idling of the monitoring equipment when no leakage occurs, resulting in energy waste, and energy can be saved.

[0024] In some optional specific embodiments, such as Figure 4 As shown, the switch circuit includes a fixed conductive block 2051 and a rotating conductive block 2052. The end of the rotating conductive block 2052 is installed on the insulating cylinder 202 through a torsion spring. The torsion spring makes the rotating conductive block 2052 always have a tendency to be connected with the fixed conductive block 2051. The toggle assembly includes a retraction cylinder 307 installed on the vertical plate 306. An insulating rod 308 is elastically installed in the retraction cylinder 307. The end of the insulating rod 308 is connected to a sloped abutment block 309. The sloped abutment block 309 is used to push the rotating conductive block 2052 in the direction away from the fixed conductive block 2051. When in use, the inclined surface supporting block 309 pushes the rotating conductive block 2052 under the action of elastic force, so that it is disconnected from the fixed conductive block 2051. When the monitoring plate 304 continues to move downward, the insulating rod 308 retracts into the retraction cylinder 307 under the mutual squeezing of the inclined surface of the inclined surface supporting block 309 and the fixed conductive block 2051, so that the monitoring plate 304 moves smoothly.

[0025] In some optional specific embodiments, such as Figure 4 As shown, the inclined surface abutting block 309 is made of rubber to avoid damage to the fixed conductive block 2051.

[0026] In some optional specific embodiments, such as Figures 1 to 3As shown, the monitoring board 304 is fixedly connected to a lifting board 303. The lifting board 303 is adaptively connected to a lead screw 301. The lead screw 301 is vertically installed in the box body 101. The end of the lead screw 301 is power-connected to a lead screw motor 302. The lead screw motor 302 is fixedly installed on the top of the box body 101, and the lead screw motor 302 is signal-connected to the control module.

[0027] In some optional specific embodiments, such as Figures 1 to 7 As shown, the inside of the conductive transmission cylinder 201 is connected to the insulating cylinder 202. The inside of the insulating cylinder 202 is connected to a heat dissipation cylinder 209. The box body 101 is provided with an air duct 401 from top to bottom. One end of the heat dissipation cylinder 209 is inserted into the air duct 401. The air duct 401 communicates with the bottom of the box body 101. A heat dissipation fan is also installed in the air duct 401 for extracting the heat transferred to the air duct 401 to the outside.

[0028] In some optional specific embodiments, such as Figure 5 As shown, a plurality of groups of heat dissipation holes 211 are formed on the side surface of the conductive transmission cylinder 201. A heat dissipation port is formed on the box body 101 opposite to the heat dissipation holes 211. A circulation hole 210 is formed in the part of the heat dissipation cylinder 209 extending into the air duct 401. The external cold air is introduced into the conductive transmission cylinder 201 from the heat dissipation port through the air duct 401 and discharged from the bottom of the box body 101.

[0029] In some optional specific embodiments, such as Figures 5 to 6As shown in the figure, a cylinder 501 is vertically arranged in the box body 101. The cylinder 501 penetrates through all the conductive transmission cylinders 201 from top to bottom. A plurality of partition components are arranged in the cylinder 501 from top to bottom. The plurality of partition components divide the interior of the cylinder 501 into a plurality of temperature sensing cavities 508. The temperature sensing cavities 508 are filled with gas. Each temperature sensing cavity 508 is respectively located in a conductive transmission cylinder 201. The partition component includes a partition plate 502 installed inside the cylinder 501. A connecting column 505 is movably installed in the partition plate 502. A first piston 503 and a second piston 507 adapted to the inside of the cylinder 501 are respectively installed at both ends of the connecting column 505. A first compression spring 504 is installed between the first piston 503 and the partition plate. A second compression spring 506 is installed between the second piston 507 and the partition plate. Two groups of contact switches are respectively installed on the connecting column 505. The two groups of contact switches are arranged on both sides of the partition plate 502. A contact piece adapted to the contact switch is installed on the partition plate 502. After the contact switch contacts the contact piece, a contact signal is sent to the control module. After receiving the contact signal, the control module generates an alarm signal. During use, each temperature sensing cavity 508 corresponds to a conductive transmission cylinder 201. When a part of the meter 103 overheats, the temperature in the corresponding conductive transmission cylinder 201 rises. It should be noted that the conductive transmission cylinder 201 is made of a heat-conducting material. At this time, because the temperature in the area adjacent to the conductive transmission cylinder 201 does not rise significantly, the gas inside the temperature sensing cavity 508 in the area where the temperature rises expands due to heat, and will squeeze its corresponding piston towards the non-overheated area. The connecting column 505 moves, and finally the contact switch contacts the contact piece, and the control module issues a local overheat alarm.

[0030] In some optional specific embodiments, the control module numbers the contact switches and corresponds the control switch numbers to the local positions of the meter 103. When the contact switch sends a contact signal, the control module checks the contact switch number and queries the corresponding local position of the meter 103. It can more accurately determine the heating position.

[0031] In some optional specific embodiments, a temperature sensor is further installed inside the box body 101 for monitoring the temperature inside the box body 101. As a supplement to temperature monitoring.

[0032] In some optional specific embodiments, such as Figure 7As shown, the contact plate 208 is connected to a movable plate 2081, which is inserted into the conductive transmission cylinder 201. The movable plate 2081 is provided with a plurality of overlapping holes 2082. The contact plate 208 is also connected to an elastic telescopic rod 207, which is mounted on the guide plate 206 and is used to tightly contact the contact plate 208 against the meter 103. The overlapping holes 2082 are matched with the heat dissipation holes 211. When the contact plate 208 is tightly in contact with the meter 103, the overlapping holes 2082 are opposite to the heat dissipation holes 211. When the contact plate 208 is not in contact with the meter 103, the overlapping holes 2082 are misaligned with the heat dissipation holes 211. The meter 103 is installed with a gap, and the contact plate 208 in the gap is not in contact with the meter 103. At this time, the overlapping holes 2082 are misaligned with the heat dissipation holes 211, reducing the connection with the outside.

[0033] The working principle of the present invention is as follows: when measuring electric energy, when a certain meter 103 has leakage, the current is transmitted to the conductive transmission cylinder 201 through the contact plate 208, and is transmitted to the conductive line 203 through the conductive transmission cylinder 201, and then flows through the conductive line 203 through the diode 204 to be transmitted to the series circuit 205, and is monitored by the electroscope 305 located at the original position. At this time, since each conductive line 203 is provided with a diode 204, the leakage between the meters 103 will not be transmitted to each other. After the electroscope 305 detects the current, the control module controls the monitoring board 304 to move toward the other end of the series circuit 205. During the movement, the electroscope When 305 reaches a certain insulating cylinder 202, the tester 305 contacts the series circuit 205 on the insulating cylinder 202. At this time, the toggle components located on the upper and lower surfaces of the monitoring board 304 disconnect the switch circuits above and below the insulating cylinder 202, so that the test result of the tester 305 is the current charging condition of the insulating cylinder 202. If it is charged, the control module determines the corresponding meter 103 according to the position of the monitoring board 304, and determines which meter 103 is leaking. Otherwise, repeat the above steps. After determining that a leakage occurs, a secondary check can be performed on the specific leakage equipment to avoid idling of the monitoring equipment when no leakage occurs, resulting in energy waste, and energy can be saved.

[0034] During use, each temperature sensing cavity 508 corresponds to a conductive transmission cylinder 201. When the meter 103 is locally overheated, the temperature in the corresponding conductive transmission cylinder 201 increases. It should be noted that the conductive transmission cylinder 201 is made of heat-conducting material. At this time, because the temperature of the area adjacent to the conductive transmission cylinder 201 has not increased significantly, the gas inside the temperature sensing cavity 508 in the temperature-rising area will expand due to the heat, and its corresponding piston will be squeezed toward the non-overheated area, and the connecting column 505 will move, eventually causing the contact switch to contact the contact sheet, and the control module will issue a local overheating alarm.

[0035] Although the present disclosure has been described in connection with specific embodiments thereof, many alternatives, modifications, and variations of these embodiments will be apparent to those of ordinary skill in the art in light of the foregoing description. For example, other memory architectures (e.g., dynamic RAM (DRAM)) may be used with the embodiments discussed.

[0036] One or more embodiments of this specification are intended to cover all such alternatives, modifications, and variations that fall within the broad scope of the appended claims. Accordingly, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included within the scope of protection of the present disclosure.
