Example 1
Referring to fig. 1 to 4, the present embodiment provides an electric energy meter verification apparatus, including: the rack 1 and the test assembly 2 are verified.
The verification rack is arranged on the base, the verification rack 1 comprises an electric energy meter fixing plate 11 and a first rotating shaft 3, and an electric energy meter fixing position is arranged on the electric energy meter fixing plate 11. The test assembly 2 comprises a movable frame 21 and test contacts 22, the movable frame 21 is connected to the first rotating shaft 3, a containing gap for containing the electric energy meter is formed in the movable frame 21 corresponding to the electric energy meter fixing position, and the test contacts 22 are arranged on one side of the movable frame 21 facing the verification rack 1 and the test contacts 22 are arranged corresponding to all the contacts of the electric energy meter placed in the containing gap.
After the movable frame 21 rotates around the first rotating shaft 3 to the verification position, the accommodating space of the movable frame 21 is aligned with the fixed position of the electric energy meter, and the test contact 22 can be in contact with all the contacts of the electric energy meter placed in the accommodating space.
It should be noted that, the electric energy meter fixing position is a position for fixing the electric energy meter, and the electric energy meter fixing component should be correspondingly arranged to facilitate the fixing of the electric energy meter. The "the movable frame 21 is connected to the first rotating shaft 3" may be that the movable frame 21 is rotatably connected to the first rotating shaft 3, or that the movable frame 21 and the first rotating shaft 3 rotate synchronously. The movable frame 21 is provided with a containing space for containing the electric energy meter corresponding to the electric energy meter fixing position, namely, the movable frame 21 is hollowed out, and when the movable frame 21 rotates to the verification position, the hollowed-out position can cover the electric energy meter on the electric energy meter fixing position.
The verification position is the position of a movable frame where a test contact of the test assembly can be contacted with a connecting contact of the electric energy meter; the opening position of the movable frame is defined opposite to the verification position, namely, the opening position of the movable frame is the position where the movable frame is opened and the test contact is separated from the connection contact of the electric energy meter.
As shown in fig. 1, as a specific arrangement scheme of the electric energy meter calibrating device of the present embodiment, the first rotating shaft 3 may be disposed above the fixed position of the electric energy meter, and the first rotating shaft 3 is disposed horizontally; the movable frame 21 comprises a connecting rod 23 and a contact rod 24, the connecting rod 23 and the contact rod 24 are vertically arranged, wherein the connecting rod 23 is vertically arranged, one end of the connecting rod 23 is connected with the first rotating shaft 3, the other end of the connecting rod 23 is connected with the contact rod 24 which is horizontally arranged, and the test contact 22 is arranged on the contact rod 24.
When the electric energy meter calibrating device is used for detecting the electric energy meter, an operator fixes the electric energy meter on the electric energy meter fixing position, specifically, an electric energy meter fixing component on the electric energy meter fixing position can be a hook capable of hanging the electric energy meter, after the electric energy meter is fixed, the operator only needs to rotate a movable frame 21 of the testing component downwards until a testing contact 22 contacts with a connecting contact of the electric energy meter, connection of the electric energy meter and a detecting circuit can be completed, and the detecting device is controlled by the detecting control screen to start detecting the electric energy meter.
According to the electric energy meter calibrating device, the movable frame 21 and the test contact 22 fixed on the movable frame 21 are arranged, the test contact 22 on the movable frame 21 is directly contacted with the connecting contact of the electric energy meter, and the electric energy meter can be calibrated, so that the electric energy meter is not required to be connected manually, the working efficiency is improved, errors of manually connecting the electric energy meter are reduced, and the calibration quality of the electric energy meter is improved.
As a specific arrangement mode of the first rotating shaft 3 of the electric energy meter calibrating device according to the embodiment of the invention, the calibrating rack 1 further comprises two vertical rods 12, the two vertical rods 12 are arranged at two sides of the electric energy meter fixing plate 11, two ends of the rotating shaft are respectively connected to the two vertical rods 12 in a rotating way, and the first rotating shaft 3 is arranged at a plate surface interval with the electric energy meter fixing plate 11.
It can be understood that the "the board spacing between the first shaft 3 and the electric energy meter fixing board 11" means that a gap is reserved between the first shaft 3 and the surface of the electric energy meter fixing board 11, so as to facilitate the rotation of the shaft.
The first shaft 3 can rotate relative to the verification housing 1, i.e. the movable frame 21 rotates synchronously with the shaft. In this way, the plurality of movable frames 21 can be driven to synchronously rotate by one rotating shaft, so that verification of a plurality of electric energy meters can be conveniently and simultaneously carried out.
As a preferred solution, the connecting rods 23 of the movable frame 21 comprise two connecting rods arranged at both ends of the contact rod 24. Each connecting rod 23 comprises a first rod 23a and a second rod 23b which are mutually sleeved, the sleeved lengths of the first rod 23a and the second rod 23b are adjustable, one end, away from the second rod 23b, of the first rod 23a is rotationally connected with the first rotating shaft 3, and one end, away from the first rod 23a, of the second rod 23b is fixedly connected with the contact rod.
It can be understood that the gap between the two connecting rods, the contact rod and the corresponding first rotating shaft is the accommodating gap for accommodating the electric energy meter by the movable frame. The first rod 23a and the second rod 23b sleeved on the two sides of the movable frame 21 form a telescopic rod, and the distance between the test contact 22 at the lower end of the movable frame 21 and the upper end of the movable frame 21 can be adjusted by adjusting the telescopic rod.
Because the heights of the connecting contacts of the electric energy meters with different specifications from the top end of the electric energy meter are different, the length of the movable frame 21 can be adjusted by the telescopic rods arranged on the two sides of the movable frame 21 according to the specifications of the electric energy meter, so that the testing contact 22 can accurately contact the connecting contacts of the electric energy meter, the electric energy meter calibrating device can be suitable for calibrating electric energy meters with various specifications, and test components do not need to be replaced frequently, so that the working efficiency is improved.
Preferably, the contact rod 24 is provided with a chute along its length, and the test contact 22 is detachably connected in the chute.
The test contact 22 can slide on the sliding groove of the movable frame 21, so that the adjustment of the test contact 22 can be conveniently carried out aiming at the electric energy meters with different specifications, thereby realizing the verification of the electric energy meters with different specifications by the electric energy meter verification device of the embodiment, avoiding frequent replacement of test components and improving the working efficiency; specifically, the test contact 22 can be fixed on the chute through a screw, so that the test contact 22 is prevented from moving on the chute at will, when the position of the test contact 22 is to be adjusted, the position of the test contact 22 can be adjusted by unscrewing the screw, and the screw is re-screwed after the adjustment is finished.
As a driving mode of the movable frame 21 of the electric energy meter calibrating device of the present embodiment, the first rotating shaft 3 is connected with a driving motor 4, and the driving motor 4 may be a servo motor.
The drive motor 4 is preferably arranged at the upper end of one of the vertical bars 12 of the assay architecture. Meanwhile, a driving motor 4 of the electric energy meter calibrating device of the embodiment is connected with an intelligent control component.
The operator inputs a corresponding control command on the verification control screen, and the intelligent control component receives the control command and controls the driving motor 4 to act according to the control command.
It can be understood that the upper end of the movable frame 21 is connected with the driving motor for driving, so that the working efficiency can be further improved, an operator only needs to fix the electric energy meter on the fixed position of the electric energy meter, and then operates on the verification control screen, so that the control motor drives the movable frame 21 to rotate downwards until the test contact 22 contacts the connection contact of the electric energy meter, and meanwhile, the driving motor can also fix the movable frame 21, so that the test contact 22 on the movable frame 21 contacts the connection contact of the electric energy meter more tightly, and the verification quality is improved.
As shown in the figure, a plurality of electric energy meter fixing positions can be arranged on the electric energy meter fixing plate 11, and a test assembly 2 is correspondingly arranged on each electric energy meter fixing position. Preferably, the plurality of electric energy meter fixing positions are arranged in rows and columns, and the corresponding movable frames 21 are also arranged in rows and columns. Preferably, the movable frames 21 of the test assemblies 2 of the same row are fixedly connected through the same first rotating shaft 3.
As shown in fig. 1, in this embodiment, the electric energy meter fixing component and the test component are two rows and four columns, and the movable frames 21 in the same row are fixedly connected to the verification rack 1 through the same first rotating shaft; correspondingly, the movable frames 21 in the same row are driven and controlled by the same driving motor.
The plurality of electric energy meter fixing positions and the plurality of test assemblies can be used for simultaneously calibrating the plurality of electric energy meters.
It is understood that the movable frames 21 of the same row are connected through the same first rotating shaft 3, so that the driving control can be realized through the same driving motor 4, thereby simplifying the number of components and optimizing the arrangement space of the components.
According to the electric energy meter calibrating device, the first rotating shaft 3 and the movable frame 21 are driven to synchronously move through the driving motor 4, so that the movable frame 21 is adjusted in the calibrating position and the opening position, and the driving motor 4 can be firmly fixed in the corresponding position because the output shaft of the driving motor 4 does not rotate when the driving motor 4 does not rotate, and the stability of contact between the test contact 22 on the movable frame 21 and a contact of an electric energy meter is enhanced.
In summary, in the electric energy meter calibrating device according to the embodiment, the electric energy meter contact and the test contact 22 are not required to be connected manually, but the test assembly 2 which is just aligned with the electric energy meter contact is adopted for docking, so that the electric energy meter contact and the test contact 22 are connected in zero error, the accuracy of electric energy meter calibration is improved, and the working efficiency is greatly improved.
