Description

Technical Field

[0001] This utility model relates to the field of electrical energy detection and measurement technology, specifically to a portable electrical energy metering device. Background Technology

[0002] The smart meter miswiring simulator is a core specialized device for power metering training, operation and maintenance training, and power skills assessment. It is mainly used to simulate the miswiring conditions of various smart meters, such as three-phase three-wire and three-phase four-wire meters, enabling power workers to conduct practical training in wiring identification, fault diagnosis, and metering error analysis. It is widely used in power supply company training bases, power vocational schools, and skills assessment institutions, and plays an important supporting role in improving the metering wiring skills of power practitioners and reducing the incidence of on-site wiring faults.

[0003] Currently, conventional smart meter miswiring simulators on the market are mainly composed of multiple smart meters, dedicated connectors, and matching connecting lines. To meet the needs of multi-condition miswiring simulation and multi-station training, the overall equipment has a large number of wiring connections and a complex wiring structure, with each functional component assembled by connecting independent lines. While this type of traditional simulator can meet basic usage requirements in fixed installation and fixed-point training scenarios, it has revealed many shortcomings in actual application, such as extremely poor equipment portability and low reliability during transportation and movement.

[0004] In scenarios requiring equipment relocation and transportation, such as adjustments to training sites, mobile teaching trips, and on-site practical assessments, the entire equipment is typically transported in a storage bag. However, during storage, handling, and movement, the lack of a fixed restraint structure within the bag allows scattered hardware components such as electricity meters and connectors to collide and be squeezed against each other irregularly, easily causing damage to the equipment casing, loosening and damaging internal components, and shortening the equipment's lifespan. Furthermore, the numerous connecting lines lack organized storage and buffer protection structures, and during transportation, these lines are continuously subjected to pulling, twisting, and squeezing forces. Frequent stress can lead to loosening and detachment of the connections between the lines and the electricity meters and connectors, directly causing poor wiring contact, circuit breaks, and other faults. This severely affects the accuracy and stability of simulation training and skills assessments involving incorrect wiring. Therefore, a portable electricity metering device needs to be designed. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problems of poor portability and easy occurrence of bumps, loosening and falling off during carrying in the prior art.

[0006] To achieve the above objectives, this utility model provides a portable electricity metering device, comprising: a box body equipped with a lid; a rotating plate that can be flipped inside the box body and rotated upward out of the box body; a support transmission mechanism that is mounted on the lid and detachably connected to the rotating plate and can flip the rotating plate upward when the lid is opened; and a support positioning mechanism that is mounted on the rotating plate and detachably connected to the box body. When the support positioning mechanism supports the rotating plate, the rotating plate is in a vertical state relative to the box body.

[0007] Preferably, one end of the rotating plate is hinged to the box body, and the support transmission mechanism includes at least one sliding connector mounted on the box cover via a connecting frame. At least one side of the rotating plate perpendicular to the hinge axis of the rotating plate is provided with a groove matching the sliding connector in the same length direction, and the groove is provided with a notch for the sliding connector to pass through.

[0008] Preferably, the notch is located on the side of the groove near the bottom of the housing.

[0009] Preferably, the support and positioning mechanism includes at least one connecting arm rotatably mounted on the rotating plate, and the connecting arm is detachably connected to the housing.

[0010] Preferably, at least one connecting block is provided on the side wall of the housing, and the end of the connecting arm away from the axis of rotation is connected to a snap-fit ​​member that can be detachably snapped into the connecting block.

[0011] Preferably, the connecting arm is connected to the rotating plate via a rotating shaft parallel to the hinge axis of the rotating plate, and the connecting block is recessed on the side near the box cover with at least one slot for inserting a card connector.

[0012] Preferably, the slot is bent and tilted at the opening end near the lid towards the rotating part of the lid.

[0013] Preferably, at least one damping telescopic rod that is rotatably connected to the box cover is rotatably connected to the inner wall of the box.

[0014] Preferably, the cabinet is equipped with a pull-out drawer.

[0015] Preferably, the inner wall of the pull-out cabinet is equipped with a partition cabinet that is parallel to the bottom of the pull-out cabinet.

[0016] According to the above technical solution, the portable electricity metering device provided by this utility model has the following beneficial effects during use: Firstly, when in use, the rotating plate can be lifted upwards and then fixed in place by the support and positioning mechanism, allowing the user to observe at eye level, which is convenient for the user and improves ease of use, while also meeting operational standards.

[0017] Secondly, the multi-position meter assembly is mounted on the rotating plate, preventing issues such as bumps, loosening of wiring, or falling off during transport and use. When stored, the multi-position meter assembly is located inside the enclosure, enhancing its protection.

[0018] Third, when the lid rotates, the rotating plate will be lifted upward through the support transmission mechanism. That is, the end of the rotating plate away from the rotation axis will rotate out from inside the box, providing a gripping position for the user to hold the rotating plate and drive it to rotate.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0024] like Figure 1-7 As shown, this embodiment discloses a portable electricity metering device, including: a housing 2 equipped with a cover 1; a rotating plate 3 that is rotatably disposed inside the housing 2 and can rotate upward out of the housing 2; a support transmission mechanism mounted on the cover 1 and detachably connected to the rotating plate 3, which can rotate the rotating plate 3 upward when the cover 1 is opened; and a support positioning mechanism mounted on the rotating plate 3 and detachably connected to the housing 2. When the support positioning mechanism supports the rotating plate 3, the rotating plate 3 is in a vertical state relative to the housing 2. A smart electricity meter and a corresponding connector 10 are mounted on the rotating plate 3.

[0025] The support and positioning mechanism of this embodiment includes at least one connecting arm 15 hinged to the rotating plate 3. The connecting arm 15 is detachably connected to the housing 2. Preferably, there are two connecting arms 15, located on both sides of the rotating plate 3 and symmetrically distributed. When it is necessary to fix the lifting angle of the rotating plate 3, the connecting arm 15 is rotated so that the connecting arm 15 is connected to the corresponding snap-fit ​​member 17. In this way, the connecting arm 15 can act as a support leg. When separating, the snap-fit ​​member 17 is separated from the connecting block 16.

[0026] One end of the rotating plate 3 is hinged to the box body 2. The supporting transmission mechanism includes at least one sliding connector 12 that is assembled on the box cover 1 via a connecting frame 11. The side of the rotating plate 3 is provided with a sliding groove 13 that matches the sliding connector 12. The sliding groove 13 is provided with a notch 14 for the sliding connector 12 to pass through. The notch 14 is open downwards, that is, it is located on the side of the sliding groove 13 closer to the box body 2.

[0027] The side of the cabinet 2 has a pull-out cabinet 4, which is located at the bottom of the turntable 3. There are some baffles and other positioning mechanisms on the upper part of the pull-out cabinet 4 to facilitate the placement of the tablet computer during use.

[0028] In the above technical solution, when the housing 2, the cover 1, and the rotating plate 3 are in the retracted state, the rotating plate 3 is parallel to the housing 2 and the cover 1. The smart energy meter and the corresponding connector 10 on the upper surface of the rotating plate 3 are located below the cover 1, and the support and positioning mechanism is in a separated state. In use, when the cover 1 is opened, its rotation will lift the rotating plate 3 upwards via the support transmission mechanism, causing the rotating plate 3 to rotate upwards. The end of the rotating plate 3 furthest from the rotation axis will rotate upwards from inside the housing 2, thus achieving... Figure 1 and Figure 2 The status is displayed to facilitate user operation and observation.

[0029] When testing is required, continue to lift the rotating plate 3 upwards to separate the rotating plate 3 from the support transmission mechanism (i.e., the slide groove 13 is disengaged from the sliding connector 12), so that the rotating plate 3 tends to be vertical. Since the rotating plate 3 tends to be vertical after the box 2 is placed on the table, it is easier for the user to observe the multi-position test meter assembly. After the rotating plate 3 tends to be vertical, it is connected to the box 2 through the support positioning mechanism to fix the use position of the rotating plate 3 and the multi-position test meter assembly.

[0030] When storing, open the support positioning mechanism and rotate the rotating plate 3 in the opposite direction so that the rotating plate 3 is reconnected to the support transmission mechanism. When closing the box cover 1, it will be restored to its original position by rotating in the opposite direction through the support transmission mechanism. At the same time, when storing, since the relative positions of the box body 2 and the box cover 1 are fixed, the position of the rotating plate 3 can also be fixed by the support transmission mechanism to prevent the rotating plate 3 from shaking inside the box body 2. It can also protect the rotating plate 3 and the multi-position measured meter assembly.

[0031] Because the multi-position meter assembly is mounted on the rotating plate 3, there will be no issues with bumps, loosening, or falling off of the wiring during transport. After storage, there are gaps between the multi-position meter assembly and the housing 2 and the cover 1. This means that even if the housing 2 and the cover 1 are slightly impacted and deformed, they will not directly press on the multi-position meter assembly, reducing the probability of damage to the multi-position meter assembly due to deformation of the housing 2 and the cover 1, and thus improving the protection of the multi-position meter assembly.

[0032] The multi-position meter assembly in this embodiment includes a first smart energy meter 8, a second smart energy meter 9, and a connector 10 connected to the first smart energy meter 8 and the second smart energy meter 9. The first smart energy meter 8 is a three-phase four-wire meter, and the second smart energy meter 9 is a three-phase three-wire meter. The control host can be a tablet computer or a laptop computer, connected to the first smart energy meter 8 and the second smart energy meter 9 via Wi-Fi. In practical applications, the tablet computer can be placed on the upper surface of the pull-out cabinet 4. The first smart energy meter 8 and the second smart energy meter 9 mentioned above are both existing technologies and will not be described in detail in this embodiment.

[0033] A lifting handle 6 is installed on one of the outer side walls of the box body 2 of this utility model. The outer side walls of the box body 2 and the lid 1 opposite to the lifting handle 6 are equipped with wheels 5. At the same time, a telescopic rod 7 is also installed at the bottom of the box body 2, which can stand the box body 2 upright so that several wheels 5 are in contact with the ground. The telescopic rod 7 makes it easy to pull the box body 2, making it easy to carry and move the box body 2. At the same time, the lifting handle 6 can lift the box body 2 upwards for carrying. With the cooperation of the wheels 5, the lifting handle 6 and the telescopic rod 7, the box body 2 can be carried in complex and changing road conditions, improving the convenience of carrying and transferring, and saving the user's physical strength.

[0034] In the above technical solution, when the rotating plate 3 is in the storage state, the sliding connector 12 is located in the slide groove 13. At this time, the sliding connector 12 and the slide groove 13 cooperate to position the rotating plate 3 and prevent the rotating plate 3 from shaking in the box 2. When the box cover 1 is opened, the connecting frame 11 drives the sliding connector 12 to move upward and lift it. At this time, the sliding connector 12 slides in the slide groove 13 and also drives the rotating plate 3 to rotate upward, that is, the rotating plate 3 can be lifted upward. The sliding connector 12 can be moved out from the notch 14, and the rotating plate 3 can be lifted further upward. The operation is simple when using it.

[0035] The side of the rotating plate 3 is equipped with a sliding groove 13, and the sliding connector 12 is cylindrical. Rollers are usually provided on its outer side to improve the convenience of operation and reduce friction.

[0036] When storage is needed, the rotating plate 3 rotates downward (to the box 2), so that the sliding connector 12 enters the slide groove 13 through the notch 14. When closing downward, the rotating plate 3 can be rotated downward and inserted into the box 2 by the cooperation of the sliding connector 12 and the slide groove 13, making storage simple and convenient.

[0037] In the above technical solution, when the notch 14 is set away from the hinge axis of the rotating plate 3, when the box cover 1 is opened, the sliding connector 12 moves upward. While the sliding connector 12 is lifted and rotated upward, it will slide away from the hinge axis of the rotating plate 3 in the slide groove 13. That is, when the sliding connector 12 slides to the end of the slide groove 13, the sliding connector 12 is located above the notch 14. When the rotating plate 3 is lifted upward, the notch 14 will just pass through the sliding connector 12 when it rotates upward, which facilitates the separation of the rotating plate 3 and the sliding connector 12, simplifies the operation steps, and improves the convenience of use. When the rotating plate 3 rotates downward, it is also convenient for the sliding connector 12 to enter the slide groove 13 through the notch 14.

[0038] The connecting arm 15 and the rotating plate 3 are connected by a damped rotational connection. In practical applications, adding rubber at the rotation point can achieve the effect of damping rotation. Under no external force, the relative position of the rotating plate 3 and the connecting arm 15 remains unchanged, preventing the connecting arm 15 from rotating arbitrarily and causing inconvenience in use. When the rotating plate 3 is in a vertical position, the connecting arm 15 can be operated to engage with the inner wall of the housing 2, fixing the rotating plate 3 in this state for convenient use.

[0039] In a preferred embodiment of this utility model, at least one connecting block 16 is mounted on the side wall of the housing 2, and a snap-fit ​​member 17 that can be detachably snapped onto the connecting block 16 is connected to the end of the connecting arm 15 away from the rotation axis. The connecting arm 15 is connected to the rotating plate 3 via a rotating shaft parallel to the hinge axis of the rotating plate 3, and at least one slot 18 for inserting the snap-fit ​​member 17 is recessed on the side of the connecting block 16 near the housing cover 1. The opening end of the slot 18 near the housing cover 1 is bent and inclined toward the rotation point of the housing cover 1.

[0040] In the above technical solution, when it is necessary to fix the use state of the rotating plate 3, the connecting arm 15 is rotated and the snap-fit ​​17 is snapped downward into the slot 18. Therefore, the function of fixing the rotating plate 3 can be achieved by the cooperation of the slot 18 and the snap-fit ​​17. The structure is simple, the operation is convenient, and the cost is low.

[0041] When the rotating plate 3 is in a vertical position, the distance between the center of gravity of the rotating plate 3 and the multi-position meter assembly and the hinge axis of the rotating plate 3 is small. In order to prevent the rotating plate 3 from rotating away from the cover 1 due to accidents or other factors, the end of the slot 18 is set to be bent and tilted towards the rotation point of the cover 1. Even if the rotating plate 3 rotates away from the cover 1, the movement of the snap-fit ​​17 in the slot 18 will be restricted by the slot 18, preventing the snap-fit ​​17 from sliding directly out of the slot 18, thereby protecting the rotating plate 3 and the multi-position meter assembly.

[0042] At least one damping telescopic rod 19 is rotatably connected to the inner wall of the housing 2 and is rotatably connected to the lid 1. The damping telescopic rod 19 can be a gas spring as in the prior art. The gas spring continuously generates thrust. When in the retracted state, the thrust causes the rotating plate 3 to be retracted inside the housing 2. When in use, the thrust keeps the lid 1 in the open state.

[0043] The damping telescopic rod 19 can fix the position of the lid 1 after it is lifted. Without external force, the lid 1 will not rotate relative to the box body 2; that is, the position of the sliding connector 12 will not change. When the rotating plate 3 is stored, the notch 14 is also directly opposite the sliding connector 12 when the rotating plate 3 is rotated downwards, which also makes it easier to store the rotating plate 3 and improves the convenience of use.

[0044] The inner wall of the pull-out cabinet 4 is equipped with partition cabinets 20 that are spaced parallel to the bottom of the pull-out cabinet 4. The partition cabinets 20 can divide the space of the pull-out cabinet 4, which can be used to place the control host or other accessories and tools. The control host can be placed alone in the partition cabinet 20 to avoid collision with other accessories and tools, which not only improves the convenience of use, but also protects the control host from bumps and knocks.

[0045] This utility model is used for simulating and restoring the wiring of power metering devices in power companies and providing auxiliary data support for power metering fault repair. It can also be used for training, learning, and research in power companies and power schools. It is currently the smallest device on the market that can achieve this type of simulation function. It is not limited by the size of the site and is particularly suitable for personnel in county power supply stations that are relatively scattered to carry out on-site work such as simulating and restoring the wiring of power metering devices, providing auxiliary calculations for metering device fault repair, studying metering device wiring, and conducting training and assessment.

[0046] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0047] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
