[0041] Figure 1 is a schematic installation diagram of a meter-reading camera in the prior art.
[0042] Refer to Figure 1 , since the pointer of the instrument and the instrument are not in the same plane, according to the principle of the straight-line propagation of light, when the lens is not directly facing the center of the instrument, the reading of the meter-reading camera (referred to as the meter-reader in the attached drawing) will deviate.
[0043] For example, when the lens of the meter-reading camera is at position A, the lens of the meter-reading camera is installed directly facing the center of the instrument. Finally, in the sensor imaging screen of the meter-reading camera, the pointer is black and the reading is accurate. When the lens of the meter-reading camera is upward and at position B, finally, in the sensor imaging screen of the meter-reading camera, the pointer is gray. Except for the readings at the positions of 0 and 6 which are accurate, the other readings all have errors. For example, for the reading of 9, the data read by the gray pointer will be smaller than the actual reading. That is, when the lens of the meter-reading camera is not directly facing the center of the instrument, the data read by the meter-reading camera will deviate, thus resulting in poor accuracy of the data read by the meter-reading camera. For this reason, the present utility model provides an auxiliary installation device for assisting in installing the meter-reading camera directly in front of the instrument.
[0044] Figure 2 is a schematic installation diagram of the auxiliary installation device provided by the embodiments of the present utility model. Figure 3It is a positioning schematic diagram of the auxiliary installation device provided by an embodiment of the present utility model. Figure 4 It is a structural schematic diagram of the auxiliary installation device provided by an embodiment of the present utility model.
[0045] Refer to Figures 2 to 4 As shown in the figure, an embodiment of the present utility model provides an auxiliary installation device for assisting a worker in positioning and installing a meter reading camera 700 at a position 10 cm - 15 cm directly in front of a meter 600, so that the lens of the meter reading camera 700 faces the center of the meter 600. The auxiliary installation device includes an installation carrier 100, a positioning component 200, and a plurality of light-emitting elements 300.
[0046] The installation carrier 100 serves as a support carrier for the auxiliary installation device and can be in a rectangular structure, a circular structure, a triangular structure, or other polygonal structures. The installation carrier 100 is detachably connected to the meter 600, that is, when the auxiliary installation device is needed to assist in installing the meter reading camera 700, it can be fixed on the surface of the meter 600 through structures such as adhesive tape, magic tape, or suction cups. When the installation is completed and the auxiliary installation device needs to be removed from the surface of the meter 600, it can be directly taken off without damaging the appearance of the meter 600.
[0047] The positioning component 200 is arranged at the center of the installation carrier 100. When the installation carrier 100 is connected to the meter 600, the projection of the positioning component 200 on the meter 600 coincides with the center of the meter 600, so that the projection of the installation carrier 100 on the meter 600 through the positioning component 200 remains coincident with the center of the meter 600 to create a positioning reference, and then positioning adjustment is performed according to the following plurality of light-emitting elements 300 arranged on the installation carrier 100.
[0048] A plurality of light-emitting elements 300 are arranged in a circumferential array along the positioning component 200 on the installation carrier 100, and each light-emitting element 300 is adapted to emit a straight line of light; when the meter reading camera 700 is installed in front of the meter 600, the position of the meter reading camera 700 is adjusted by the straight line of light emitted by each light-emitting element 300, so that the lens of the meter reading camera 700 faces the center of the meter 600, that is: as Figure 3 shown, the lens of the meter reading camera 700 and the center of the meter 600 are on the same horizontal line. Thus, the problem of reading errors caused by the meter reading camera 700 not facing the meter 600 directly is solved.
[0049] It can be understood that for the auxiliary installation device provided by the embodiments of the present utility model, by providing an installation carrier 100 and arranging a positioning component 200 at the central position of the installation carrier 100 for alignment with the center of the instrument 600, the positioning between the installation carrier 100 and the instrument 600 is achieved. Then, a plurality of light-emitting elements 300 are arranged in an array around the positioning component 200. When the meter-reading camera 700 is installed in front of the instrument 600, the position of the meter-reading camera 700 is adjusted by the straight-line light rays emitted by each light-emitting element 300, so that the lens of the meter-reading camera 700 is directly facing the center of the instrument 600, thereby solving the problem of reading errors caused by the meter-reading camera 700 not being directly facing the instrument 600.
[0050] In addition, the auxiliary installation device provided by the embodiments of the present utility model has a simple structural design, is convenient to carry and use, and has strong practicability.
[0051] Figure 5 It is a side view of the auxiliary installation device provided by the embodiments of the present utility model.
[0052] Refer to Figure 4 and also refer to Figure 5 In some embodiments of the present utility model, the positioning component 200 includes a first light source 210 and a second light source 220. The straight-line light rays emitted by the first light source 210 and the second light source 220 intersect to form a preset intersection point O, and the projection of the preset intersection point O on the instrument 600 coincides with the center of the instrument 600.
[0053] When the first light source 210 and the second light source 220 are turned on simultaneously, the light rays emitted by the first light source 210 and the second light source 220 form a preset intersection point O. Since the positions of the first light source 210 and the second light source 220 can determine the position of the preset intersection point O, therefore, the position of the preset intersection point O can be selectively determined according to the positions of the first light source 210 and the second light source 220, so that the preset intersection point O can meet the corresponding range adjustment in different scenarios.
[0054] By making the projection of the preset intersection point O on the instrument 600 coincide with the center of the instrument 600, it can be determined that the installation carrier 100 is located at the central position of the instrument 600, and the position adjusted by the meter-reading camera 700 with reference to the multiple light-emitting elements 300 arranged on the installation carrier 100 can be more accurate.
[0055] Since the auxiliary installation device is detachably connected to the front of the instrument 600, therefore, when looking at the instrument 600 from the front view direction, when the preset intersection point O is located at the center of the instrument 600, it is determined that the preset intersection point O coincides with the center of the instrument 600.
[0056] The first light source 210 and the second light source 220 can be arranged on the installation carrier 100 in the following two ways.
[0057] The first method: A through hole 110 can be opened at the middle position of the mounting carrier 100, and then the first light source 210 and the second light source 220 are installed on the hole wall of the through hole 110. Since the through hole 110 is arranged in a penetrating manner without any obstruction, when the straight light rays emitted by the first light source 210 and the second light source 220 intersect, the position of the intersection point can be clearly seen.
[0058] The second method: The middle area of the mounting carrier 100 can be set to be composed of a transparent material, that is, it can be seen through from one side of the mounting carrier 100 to the other side. At this time, the first light source 210 and the second light source 220 are installed on any side of the mounting carrier 100, as long as the straight light rays emitted by the first light source 210 and the second light source 220 intersect to form a preset intersection point O and can be seen through the transparent area.
[0059] In addition, the positioning component 200 can also be a thimble or a protrusion arranged on the surface of the mounting carrier 100 facing the meter 600. Correspondingly, a groove matching with the thimble or the protrusion is opened at the center position of the meter 600. When the thimble or the protrusion arranged on the mounting carrier 100 is paired with the groove located on the meter 600, it is determined that the centers of the mounting carrier 100 and the meter 600 are on the same horizontal line.
[0060] Refer to Figure 4 and Figure 5 , in some embodiments of the present invention, a circular through hole 110 is opened at the center of the mounting carrier 100, the first light source 210 and the second light source 220 are arranged on the side wall of the mounting carrier 100, and the straight light rays emitted by the first light source 210 and the second light source 220 intersect vertically.
[0061] With such a setting, after the straight light rays emitted by the first light source 210 and the second light source 220 intersect vertically, the intersection point is the virtual center of the through hole 110, which can make the positioning of the mounting carrier 100 more accurate.
[0062] Figure 6 is a schematic diagram of the movement of the light-emitting element 300 of the auxiliary installation device provided by the embodiment of the present invention.
[0063] Refer to Figure 6 , a plurality of light-emitting elements 300 are all movably arranged on the mounting carrier 100 to synchronously adjust their respective positions according to the size of the meter-reading camera 700, so that the straight light rays emitted by each light-emitting element 300 are suitable for irradiating to the corresponding first target point Q1, and the distance between each first target point Q1 and the center of the meter-reading camera 700 is equal.
[0064] For example, when the meter reading camera 700 is square, the first target points Q1 can be the four vertices of the meter reading camera 700. At this time, the straight light rays emitted by each light-emitting element 300 can coincide with the edges of the meter reading camera 700, or the straight light rays emitted by each light-emitting element 300 irradiate the vertices of the meter reading camera 700.
[0065] Since three points determine a plane, when the meter reading camera 700 has a rectangular structure and the front of the meter reading camera 700 is square, that is, the meter reading camera 700 has four edges and the lens of the meter reading camera 700 is located at the center position of the meter reading camera 700. When the straight light rays emitted by each light-emitting element 300 coincide with the four edges of the meter reading camera 700 respectively, it is considered that the lens of the meter reading camera 700 is facing the center of the meter 600 at this time. Or, when the straight light rays emitted by each light-emitting element 300 irradiate the vertices of the meter reading camera 700, it is considered that the lens of the meter reading camera 700 is facing the center of the meter 600 at this time.
[0066] For example, six laser lights A, B, C, D, E, and F are provided on the front of the meter reading camera 700. Each laser light can emit visible straight light rays. The four laser lights A, B, C, and D are installed in the sliding grooves 120 around the hole wall of the through hole 110. A through hole 110 is provided at the center of the mounting carrier 100. The two laser lights E and F are installed on the hole wall of the through hole 110 and both vertically face the opposite side of the through hole 110. The straight light rays emitted by the two laser lights E and F are perpendicular to each other, and the intersection point of the straight light rays emitted by the two laser lights E and F passes through the midpoint of the through hole 110. A switch for controlling the opening or closing of each laser light is further provided on the mounting carrier 100, which can realize controlling the six laser lights to be turned on or off together, and controlling some of the six laser lights to be turned on or off.
[0067] Continue to refer to Figure 4 , in some embodiments of the present invention, a sliding groove 120 is provided on the surface of the mounting carrier 100. The groove wall of the sliding groove 120 is provided with damping. The light-emitting element 300 is disposed between two adjacent dampings and is adapted to overcome the damping under the action of a driving force to slide along the sliding groove 120, thereby changing the position of the light-emitting element 300.
[0068] Among them, the damping can be a protrusion made of plastic material. The protrusions are arranged at intervals on the groove wall of the sliding groove 120. When the light-emitting element 300 is pushed by an external force, the light-emitting element 300 overcomes the resistance of the next damping to realize the sliding of the light-emitting element 300 along the sliding groove 120. When the light-emitting element 300 is not pushed by an external force, the plastic protrusions provide a limit for the light-emitting element 300 to keep the light-emitting element 300 at the corresponding position in the sliding groove 120, thereby realizing manual adjustment of the position of the light-emitting element 300 to adapt to the installation of meter reading cameras 700 of different specifications.
[0069] Continue to refer to Figure 4 , at least one side of the sliding groove 120 is provided with a scale value 130, and the scale value 130 is used to represent the position of the light-emitting element 300.
[0070] By setting the scale value 130 on one or both sides of each sliding groove 120, when manually adjusting the position of the light-emitting element 300 in the sliding groove 120, it is adjusted according to the scale value 130, so that the positions of each light-emitting element 300 in the corresponding sliding groove 120 can be kept consistent, and the position accuracy of the meter-reading camera 700 is further improved.
[0071] Figure 7 FIG. is a schematic structural diagram of each light-emitting element 300 of the auxiliary installation device provided by the embodiment of the present invention located at a position. Figure 8 FIG. is a schematic structural diagram of each light-emitting element 300 of the auxiliary installation device provided by the embodiment of the present invention located at another position.
[0072] Continue to refer to Figure 7 and Figure 8 , in some embodiments of the present invention, the installation carrier 100 is provided with a sliding groove 120, and the light-emitting element 300 is slidably arranged in the sliding groove 120; a telescopic member 400 is arranged between two adjacent light-emitting elements 300, and one of the telescopic members 400 is connected with a holding member 500. Under the action of a driving force, the holding member 500 is adapted to drive the telescopic member 400 to perform synchronous telescoping, so that the light-emitting element 300 slides synchronously along the corresponding sliding groove 120, thereby changing the position of the light-emitting element 300 in the corresponding sliding groove 120.
[0073] Wherein, the telescopic member 400 can be composed of a plurality of rigid sleeve and rod assemblies arranged in a nested manner, the diameter of the sleeve is larger than the diameter of the rod, and the rod is slidably connected to the inner wall of the sleeve through structures such as a slide rail, and the holding member 500 can be connected to the sleeve or the rod. By pulling the sleeve or the rod to move through the holding member 500, the telescopic member 400 can be sequentially extended or shortened, so as to synchronously adjust the positions of a plurality of light-emitting elements 300 in the corresponding sliding grooves 120.
[0074] For example, the telescopic member 400 is composed of three-stage telescopic rods nested together, telescopic members 400 are arranged between AB, BD, DC and CA, the telescopic member 400 is hinged to the corresponding light-emitting element 300, and the holding member 500 can be connected to the telescopic member 400 between any one of AB, BD, DC and CA, that is, the telescopic member 400 is connected to the telescopic member 400 between BD.
[0075] When the meter reading camera 700 is smaller in size and the plurality of light emitting elements 300 need to approach the positioning member 200, force is applied to the gripping member 500 so that the gripping member 500 drives the telescopic member 400 to contract synchronously. When the meter reading camera 700 is larger in size and the plurality of light emitting elements 300 need to move away from the positioning member 200, force is applied to the gripping member 500 so that the gripping member 500 drives the telescopic member 400 to extend synchronously.
[0076] Since the four light emitting elements 300 of A, B, C and D are hinged together by the telescopic member 400, and the slide groove 120 limits the movement trajectory of each light emitting element 300, the gripping member 500 can be applied with force to drive the telescopic members 400 between AB, BD, DC and CA to telescope synchronously. And since the telescopic member 400 is a rigid member, the telescopic distances of the telescopic members 400 between AB, BD, DC and CA are equal, so that the position of each light emitting element 300 relative to the center of the mounting carrier 100 is equal.
[0077] In some embodiments of the utility model, the mounting carrier 100 is provided with a slide groove 120, and the light-emitting element 300 is slidably arranged in the slide groove 120; a driving component and a transmission component are arranged inside the mounting carrier 100, the driving component is used to provide a driving force, and the transmission component is connected between the driving component and the light-emitting element 300, and is used to transmit the driving force of the driving component to the light-emitting element 300, so that the light-emitting element 300 slides along the slide groove 120.
[0078] The driving component includes a motor, and the moving distance of the light emitting element 300 can be controlled to be consistent by controlling the rotation angle of the motor. The transmission component includes a screw, a screw nut and a guide. The screw is connected to the mounting carrier 100 and connected to the output end of the motor. The guide is fixedly connected to the mounting carrier 100, the screw nut is threadedly matched with the screw, the screw nut is slidably matched with the guide, and the light emitting element 300 is arranged on the screw nut.
[0079] In addition, the transmission components can also be driven by chains or racks.

[0081] See also Figure 9 The auxiliary installation device also includes a reference piece 800, and a positioning hole 810 is provided at the center of the reference piece 800; when the lens of the meter reading camera 700 is not at the center of the meter reading camera 700, the reference piece 800 can be connected to the meter reading camera 700 by pasting, and the positioning hole 810 is aligned with the lens of the meter reading camera 700.
[0082] When the installation carrier 100 is connected to the meter 600, when the straight light rays emitted by each light-emitting element 300 irradiate the corresponding second target point Q2, the lens of the meter-reading camera 700 is facing the center of the meter 600. Among them, the distance between each second target point Q2 and the center of the reference member 800 is equal. For example, the reference member 800 is square.
[0083] That is, when the lens of the meter-reading camera 700 is not at the center of the meter-reading camera 700, a reference member 800 is pasted on the side of the meter-reading camera 700 facing the installation carrier 100. The positioning hole 810 of the reference member 800 is aligned with the lens of the meter-reading camera 700. By adjusting the straight light rays emitted by the light-emitting element 300 to be aligned with the edges of the reference member 800, the lens of the meter-reading camera 700 can be made to face the center of the meter 600.
[0084] Since when the lens of the meter-reading camera 700 is not at the center of the meter-reading camera 700, if the position of the meter-reading camera 700 continues to be adjusted by referring to the coincidence of the edge of the meter-reading camera 700 and the straight light rays emitted by the light-emitting element 300, there will be a certain deviation. Therefore, by setting the reference member 800, the structure around the lens of the meter-reading camera 700 is supplemented to a regular rectangular structure, so that it is more accurate to adjust the position of the meter-reading camera 700 by referring to the coincidence of the edge of the reference member 800 and the straight light rays emitted by the light-emitting element 300.
[0085] Among them, the reference member 800 can be a sticker or a label. The reference member 800 has a certain strength and can be pasted on the surface of the meter-reading camera 700.
[0086] In actual use, for the auxiliary installation device provided by the embodiment of the present invention, first, the meter-reading camera 700 is pre-installed, and then the auxiliary installation device is arranged on the surface of the meter 600 through an adhesive or a suction cup. Then, the switch of the light-emitting element 300 in the auxiliary installation device is turned on. Through the through hole 110 in the middle of the installation carrier 100, the preset intersection point O of the two light-emitting elements 300, namely E and F, is aligned with the center of the meter 600. Then, the positions of the four light-emitting elements 300, namely A, B, C, and D, are adjusted so that the distances between the four light-emitting elements 300 and the center of the through hole 110 are equal. Around the lens of the meter-reading camera 700, the installation position of the meter-reading camera 700 is adjusted so that the four light-emitting elements 300 are evenly distributed around the lens.
[0087] When the meter-reading camera 700 has a square structure, the lens of the meter-reading camera 700 is located at the center of the meter-reading camera 700. When the straight light rays generated by the four light-emitting elements 300 reach the edges where the four corners of the meter-reading camera 700 are located, it is considered that the installation position of the meter-reading camera 700 is accurate. When the meter-reading camera 700 is installed obliquely or offset, the straight light rays generated by the four light-emitting elements 300 cannot reach the edges where the four corners of the meter-reading camera 700 are located.
[0088] When the meter-reading camera 700 does not have a square structure, it is necessary to find points or edges equidistant from the lens of the meter-reading camera 700. At this time, the reference part 800 can be used for auxiliary adjustment; or the lens window can be directly used for auxiliary adjustment.
