Description

Technical Field

[0001] This application relates to the field of power measurement technology, and more specifically, to a moisture-proof outdoor power meter. Background Technology

[0002] An electricity meter, also known as an energy meter, is an instrument used to measure and record electricity consumption. It is widely used in residential, industrial, and commercial electricity consumption scenarios. When used outdoors, it is usually installed in a special protection device to ensure safe operation and facilitate management and maintenance.

[0003] In related technologies, for example, the prior art patent with publication number CN208060580U provides an outdoor moisture-proof smart meter. This device is equipped with a moisture-proof dehumidifier and uses a humidity detector to detect the humidity inside the meter box in real time. Then, based on the data inside the humidity detector, moisture-absorbing particles and moisture-absorbing ports work together to dehumidify the inside of the meter box, preventing the internal components of the meter box from getting damp and moldy, and further ensuring the normal operation of the meter.

[0004] Although the existing technical solutions mentioned above dehumidify the inside of the meter box by working together with the moisture-absorbing particles and the moisture-absorbing port, the meter's card slot lacks a sealing structure, which causes some moisture to enter the meter through the unfolded card slot. Over time, the moisture will condense inside the meter, and may even cause short circuits at the contact points of the circuit board inside the meter.

[0005] In view of this, we propose a moisture-proof outdoor energy meter. Utility Model Content

[0006] The purpose of this application is to provide a moisture-proof outdoor electricity meter that can effectively solve the problem in the prior art where moisture enters the inside of the electricity meter through the card slot, causing the inside of the electricity meter to become damp, and achieves the effect of preventing moisture inside the card slot of the electricity meter.

[0007] This application provides a moisture-proof outdoor power meter, including:

[0008] An electricity meter, wherein a display is mounted on the outer wall of the electricity meter;

[0009] A card slot is provided on the outside of the electricity meter for inserting an electricity card;

[0010] A sealing mechanism, wherein the sealing mechanism is disposed inside the meter;

[0011] The sealing mechanism includes a sealing plate that slides inside the meter to seal the card slot. A magnetic plate is provided on the outside of the sealing plate, and the magnetic plate is attracted to the inner wall of the meter.

[0012] As an optional solution to the technical solution of this application, the sealing mechanism further includes a movable plate that is slidably disposed on the inner wall of the meter. The movable plate is fixedly connected to the sealing plate and the magnetic plate. A pull rod is fixedly connected to the outer side of the movable plate. The end of the pull rod passes through one side of the meter and is slidably disposed.

[0013] As an optional solution to the technical solution of this application, the side wall of the meter has two placement slots, and a heat sink B is fixed to the inner wall of the placement slot to disperse the heat inside the meter outward.

[0014] As an optional solution to the technical solution of this application, the bottom of the meter has two flow channels, which are connected to the placement channel. A fan is installed inside the flow channel to drive air to flow between the placement channel and the flow channel.

[0015] As an optional solution to the technical solution in this application, a card reader is installed inside the electricity meter. The card reader is located on one side of the card slot, and a heat sink A is installed on the other side of the card slot to dissipate heat from the card slot and the card reader inside.

[0016] As an optional solution to the technical solution of this application, a sealing ring is fixedly connected to the outer wall of the meter, and the inner circumferential wall of the sealing ring is interference-fitted with the outer wall of the pull rod.

[0017] As an optional solution to the technical solution in this application, multiple caps are installed at the corners of the meter.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] (1) This application uses a sealing mechanism, so that the sealing plate can seal the card slot after contacting the card slot, reducing the problem of moisture entering the inside of the meter through the card slot and causing the inside of the meter to become damp, thus achieving the effect of moisture prevention inside the card slot of the meter. In addition, the sealing ring sleeve can prevent moisture from entering through the connection gap of the pull rod.

[0020] (2) By using the heat sink B that is set up in conjunction with the existing electricity meter, the problem that a lot of dust or moisture can easily enter the inside of the electricity meter is reduced due to the large number of heat dissipation holes on the original electricity meter. In addition, the fan can improve the overall cooling speed of the heat sink B, further improving the overall stability of the electricity meter in use. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-5 This application discloses a moisture-proof outdoor electricity meter, comprising a meter 1, a card slot 2, and a sealing mechanism 3. A display 11 is mounted on the outer wall of the meter 1. The card slot 2 is located outside the meter 1 and is used to insert an electricity card 100. The sealing mechanism 3 is located inside the meter 1. The sealing mechanism 3 includes a sealing plate 31 slidably disposed within the meter 1 to seal the card slot 2. A magnetic plate 32 is disposed on the outer side of the sealing plate 31, and the magnetic plate 32 is attracted to the inner wall of the meter 1. The sealing mechanism 3 also includes a movable plate 33 slidably disposed within the inner wall of the meter 1. The movable plate 33 is fixedly connected to the sealing plate 31 and the magnetic plate 32. A pull rod 34 is fixedly connected to the outer side of the movable plate 33, and the end of the pull rod 34 penetrates one side of the meter 1 and is slidably disposed. A sealing ring 17 is fixedly connected to the outer wall of the meter 1, and the inner circumferential wall of the sealing ring 17 is interference-fitted with the outer wall of the pull rod 34.

[0029] After installing the electricity meter 1 in its outdoor protective casing, the electricity card 100 can be inserted into the card slot 2 and read, with the reading displayed on the monitor 11. After the electricity card 100 disengages from the card slot 2, the operator can pull the lever 34 outwards. This causes the movable plate 33 to slide, and the sealing plate 31 and magnetic plate 32 to gradually approach the card slot 2. Upon contact with the metal inner wall of the electricity meter 1, the magnetic plate 32 generates an attractive force, causing the sealing plate 31 to adhere tightly to the card slot 2. The sealing plate 31 seals the card slot 2 and the soft material sealing ring 17 seals the connection gap between the pull rod 34 and the meter 1. After the sealing plate 31 contacts the card slot 2, it seals the card slot 2, reducing the problem of moisture entering the meter through the card slot and causing the meter to become damp. This achieves the effect of preventing moisture inside the meter card slot. The sealing ring 17 also reduces the problem of some moisture entering through the connection gap of the pull rod 34.

[0030] Reference Figure 1 and Figure 2 The meter 1 has two placement slots 13 on its side wall, and a heat sink B14 is fixed to the inner wall of the placement slot 13 to disperse the heat inside the meter 1 outward. The meter 1 has two flow guide slots 15 at its bottom, and the flow guide slots 15 are connected to the placement slots 13. A fan 16 is installed inside the flow guide slots 15 to drive the air to flow between the placement slots 13 and the flow guide slots 15.

[0031] By providing a placement slot 13 on the side wall of the meter 1, the heat generated inside the meter 1 can be gathered on the heat sink B14 and dissipated outward through the air fins. When the heat inside the meter 1 accumulates severely and the temperature rises continuously until it reaches the threshold of the temperature sensor inside the meter 1, the fan 16 can be switched on. This allows the airflow at the end of the fan 16 to pass through the guide slot 15 and accelerate the airflow near the placement slot 13 and the heat sink B14. This step, together with the unfolded heat sink B14, can reduce the problem of dust or moisture easily entering the meter 1 due to the numerous heat dissipation holes on the original meter 1. Furthermore, the fan 16 can improve the overall cooling speed of the heat sink B14, further improving the overall stability of the meter 1 during use.

[0032] Reference Figure 4The meter 1 has a card reader 21 installed inside. The card reader 21 is located on one side of the card slot 2. A heat sink A12 is installed on the other side of the card slot 2 to dissipate heat from the card slot 2 and the card reader 21 inside. When some heat is concentrated at the card reader 21, the unfolded heat sink A12 can dissipate the heat near the card reader 21. This step, under the action of the heat sink A12, can reduce the gradual increase in the surface temperature of the card reader 21, thus reducing the impact on the subsequent card reading sensitivity of the electric card 100.

[0033] Reference Figure 1 and Figure 3 Multiple caps 4 are installed at the corners of the meter 1. The caps 4 are fitted onto the bolts of the meter 1, so that the unfolded caps 4 can cover the bolts. The caps 4 can also be removed later. This step, under the action of the caps 4, can reduce the corrosion of the bolts due to long-term storage, thereby affecting the subsequent disassembly or installation work.

[0034] In summary, when using the moisture-proof outdoor energy meter disclosed in this application embodiment, after the meter 1 is installed in the outdoor protective casing, the card 100 can be inserted into the card slot 2, and the card 100 can be read and displayed on the display 11. After the card 100 is disengaged from the card slot 2, the operator can pull the lever 34 outward, so that the movable plate 33 slides and the sealing plate 31 and magnetic plate 32 gradually approach the position of the card slot 2. After the magnetic plate 32 contacts the metal inner wall of the meter 1, it generates an attractive force, and the sealing plate 31 is tightly attached to the position of the card slot 2, thus completing the sealing work of the card slot 2. At the same time, the soft material sealing ring 17 can also prevent the connection between the lever 34 and the meter 1. The gap is sealed by setting a placement groove 13 on the side wall of the meter 1, so that the heat generated inside the meter 1 can be gathered on the heat sink B14 and dissipated outward through the air fins. When the heat inside the meter 1 is serious and the temperature continues to rise and reaches the threshold of the temperature sensor inside the meter 1, the fan 16 switch can be turned on, so that the airflow at the end of the fan 16 can pass through the guide groove 15 and accelerate the airflow near the placement groove 13 and the heat sink B14. When some heat gathers at the card reader 21, the unfolded heat sink A12 can exhaust the heat near the card reader 21. With the cover 4 sleeved on the bolt of the meter 1, the unfolded cover 4 can cover the bolt, and the cover 4 can be removed later.
