Description

Technical Field

[0001] This application relates to the field of electricity meter testing technology, and in particular to a mounting bracket for testing wall-mounted electricity meters. Background Technology

[0002] After the wall-mounted energy meter is manufactured, it needs to be randomly sampled and tested to determine whether its performance meets the requirements.

[0003] Basic performance tests of wall-mounted energy meters, such as basic error tests, voltage influence tests, and constant tests, all require the acquisition of photoelectric pulse signals output by the wall-mounted energy meter using a photoelectric sampler. During this process, data acquisition anomalies often occur, such as inaccurate or unstable data.

[0004] The root cause was found to be that the wall-mounted energy meters installed on the existing mounting brackets were prone to swaying after being subjected to slight vibrations during the test, thus deviating from their original correct sampling position. As a result, the photoelectric sampler could not accurately collect the photoelectric pulse signal output by the wall-mounted energy meters, causing abnormal data acquisition.

[0005] To ensure the accuracy of the test results, the testing personnel need to continuously adjust the position of the wall-mounted energy meter during the test to ensure that the photoelectric pulse signal is accurately collected. At the same time, the testing personnel also need to monitor the data collection in real time. This not only increases the manual labor hours but also greatly reduces the work efficiency. Utility Model Content

[0006] This utility model provides an installation bracket for testing wall-mounted energy meters, which improves the positional offset phenomenon during testing of wall-mounted energy meters and enhances the accuracy of data acquisition.

[0007] The technical solution of this application is as follows:

[0008] The mounting bracket for testing wall-mounted energy meters provided in this application includes a mounting plate and a base. Along a first direction, the base is located at one end of the mounting plate and is used to fix the mounting plate. Along a second direction, one side of the mounting plate is used to mount the wall-mounted energy meter.

[0009] The mounting plate also has a first limiting structure and a second limiting structure. The first limiting structure is used to mount the wall-mounted energy meter to determine the position of the wall-mounted energy meter in a first direction. The second limiting structure is used to determine the position of the wall-mounted energy meter in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0010] The mounting bracket for testing wall-mounted energy meters provided in this application includes both a first limiting structure for determining the installation height of the wall-mounted energy meter in a first direction and a second limiting structure for determining the position of the wall-mounted energy meter in a third direction. Thus, when the wall-mounted energy meter encounters vibration during testing, even if there is a gap in the fit between the wall-mounted energy meter and the first limiting structure, the presence of the second limiting structure prevents the wall-mounted energy meter from swinging around the mounting point in a third direction. This makes the position of the wall-mounted energy meter more stable, the position of the pulse lamp more stable, and improves the accuracy of data acquisition.

[0011] On the other hand, since the position of the wall-mounted energy meter is relatively stable during the testing process, there is no need to adjust the position of the wall-mounted energy meter, thus saving manpower and helping to improve testing efficiency.

[0012] In one possible design, the first limiting structure includes multiple installation stations, each of which can be used to mount a wall-mounted energy meter, and the multiple installation stations are arranged along a first direction.

[0013] The mounting bracket for testing wall-mounted energy meters provided in this embodiment includes a first limiting structure comprising multiple mounting positions arranged along a first direction, each capable of housing a wall-mounted energy meter. This allows the mounting position of the wall-mounted energy meter to be determined based on its specifications, enabling the same mounting bracket to be used for testing and installing various specifications of wall-mounted energy meters, thus helping to reduce testing costs.

[0014] In one possible design, there is a gap between two adjacent installation stations, and each installation station is provided with a first limiting hole. The first limiting structure also includes a hanging post, which can be detachably connected to any of the first limiting holes, and one end of the hanging post protrudes from the first limiting hole for hanging a wall-mounted energy meter.

[0015] The mounting bracket for testing wall-mounted energy meters provided in this embodiment has a gap between two adjacent installation positions, and each installation position is provided with a first limiting hole. Therefore, the multiple first limiting holes are independent of each other. Thus, when the wall-mounted energy meter is hung on the mounting plate, even in a vibration environment, the wall-mounted energy meter will not move from one installation position to another. This helps improve the positional accuracy of the wall-mounted energy meter in the first direction, thereby improving the accuracy of data acquisition.

[0016] In one possible design, the first limiting hole is a screw hole that penetrates the mounting plate along the second direction, and the mounting post is a screw. This structure is easy to implement and simple to operate.

[0017] In one possible design, the mounting post includes a head, neck, shoulder, and screw section connected in sequence, wherein the radial dimension of the neck is the smallest and the radial dimension of the shoulder is the largest.

[0018] Based on the mounting bracket for testing wall-mounted energy meters provided in this embodiment, the mounting post of this structure has a screw section threadedly connected to the first limiting hole during use. The head, neck, and shoulder protrude outside the first limiting hole. The shoulder is used for positioning the mounting post in the second direction, and the neck is used to cooperate with the hanging ring of the wall-mounted energy meter. The mounting post of this structure is easy to accurately position and install on the mounting plate, and is relatively convenient to use.

[0019] In one possible design, the second limiting structure includes two movable adjusting members. Along a third direction, the two movable adjusting members can move towards each other or away from each other, and the two movable adjusting members are located on opposite sides of the first limiting structure.

[0020] Based on the mounting bracket for testing the wall-mounted energy meter provided in this embodiment, movable adjustment members are provided on opposite sides of the first limiting structure along the third direction. In this way, when the wall-mounted energy meter is installed, the distance between the two movable adjustment members can be adjusted so that the two movable adjustment members can be adapted to the size of the wall-mounted energy meter in the third direction, thereby better limiting the wall-mounted energy meter in the third direction and preventing the wall-mounted energy meter from shaking in the third direction.

[0021] In one possible design, the second limiting structure includes two second limiting holes, each corresponding to one of the two movable adjusting members.

[0022] The second limiting hole is a straight hole extending in the third direction and penetrating the mounting plate in the second direction.

[0023] The movable adjusting component includes a screw, a retaining ring, and a nut. The screw is inserted into the second limiting hole. The retaining ring and the screw are located on both sides of the mounting plate, and both can be threadedly connected to the screw to clamp the mounting plate.

[0024] The mounting bracket for testing wall-mounted energy meters provided in this embodiment has a second limiting hole that is a slotted hole, and the movable adjusting components include screws, retaining rings, and nuts. When installing the wall-mounted energy meter, the installation position of the screw in the third direction of the second limiting hole can be determined according to the size of the wall-mounted energy meter. After determining the position, the retaining ring and nut are rotated to clamp the mounting plate. In this way, the position of the movable adjusting components on the mounting plate is fixed, and the distance between the two movable adjusting components in the third direction is determined, thus preventing the wall-mounted energy meter from shaking in the third direction.

[0025] In one possible design, the base includes a base plate and multiple triangular support plates. The base plate is perpendicular to the mounting plate and fixed to the bottom of the mounting plate. Along a second direction, multiple triangular support plates are symmetrically arranged on opposite sides of the mounting plate and are fixedly connected to the mounting plate and the base plate.

[0026] The mounting bracket for testing wall-mounted energy meters provided in this embodiment includes a base plate and multiple triangular support plates. These triangular support plates are symmetrically arranged on opposite sides of the mounting plate and fixedly connected to both the mounting plate and the base plate. This forms multiple triangular support structures between the triangular support plates, the base plate, and the mounting plate, enhancing the stability of both the base and the mounting bracket. During performance testing of the wall-mounted energy meter, the mounting bracket is less likely to tip over when encountering vibrations, facilitating smooth testing.

[0027] In one possible design, a rubber pad is also provided on the side of the base plate away from the mounting plate.

[0028] The mounting bracket for testing wall-mounted energy meters provided in this embodiment has a rubber pad on the side of the base plate away from the mounting plate. This helps to increase the anti-slip properties of the mounting bracket, prevent the mounting bracket from deviating from the predetermined position, and thus improve the accuracy of sampling.

[0029] In one possible design, the base and mounting plate are made of bakelite.

[0030] The mounting bracket for testing wall-mounted energy meters provided in this embodiment uses bakelite as the material for both the base and the mounting plate. This helps maintain insulation between the mounting bracket and the wall-mounted energy meter, improving testing accuracy. Furthermore, bakelite has a relatively high density among insulating materials, which helps increase the overall mass of the mounting bracket. Greater mass results in better stability and reduces the likelihood of tilting, which also contributes to improved sampling accuracy. Attached Figure Description

[0052] The present application will be described in detail below with reference to the accompanying drawings.

[0053] Figure 1 The image shown is a front view of a conventional wall-mounted energy meter. Figure 2 Here is a rear view of an existing wall-mounted energy meter. Please refer to the image. Figure 1 and Figure 2 .

[0054] Existing wall-mounted energy meters typically have a pulse lamp 11 on the front and a hanging ring 12 on the back. When performing performance tests on wall-mounted energy meters, they are usually mounted on a mounting bracket, and a photoelectric sampler is placed on the front of the meter to collect the pulse signals emitted by the pulse lamp 11.

[0055] Figure 3 The diagram shown is a structural schematic of a wall-mounted energy meter testing mounting bracket provided by related technologies. Please refer to it. Figure 3In related technologies, the mounting bracket for testing wall-mounted energy meters includes a mounting plate 31 and a base 32. The base 32 is a horizontal plate, arranged in the horizontal direction, and the mounting plate 31 is a vertical plate, arranged in the vertical direction. The mounting plate 31 is provided with a first limiting structure 33 for hanging the wall-mounted energy meter to determine the vertical position of the wall-mounted energy meter.

[0056] When a wall-mounted energy meter using this mounting bracket is subjected to slight vibrations during testing, it is prone to swaying, causing it to deviate from its original correct sampling position. Consequently, the photoelectric sampler cannot accurately collect the photoelectric pulse signal output by the wall-mounted energy meter, resulting in abnormal data acquisition.

[0057] In view of this, this application provides a mounting bracket for testing a wall-mounted energy meter. Figure 4 This is a schematic diagram of the structure of a mounting bracket for testing a wall-mounted energy meter, provided in an embodiment of this application. Figure 5 for Figure 4 Side view.

[0058] like Figure 4 and Figure 5 As shown, the mounting bracket for testing a wall-mounted energy meter provided in this application includes a mounting plate 31 and a base 32. Along the first direction D1, the base 32 is located at one end of the mounting plate 31 and is used to fix the mounting plate 31. Along the second direction D2, one side of the mounting plate 31 is used to mount the wall-mounted energy meter. The mounting plate 31 is also provided with a first limiting structure 33 and a second limiting structure 34. The first limiting structure 33 is used to hang the wall-mounted energy meter to determine its position in the first direction D1. The second limiting structure 34 is used to determine the position of the wall-mounted energy meter in the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0059] Specifically, please combine Figure 1 , Figure 2 , Figure 4 and Figure 5 In this application, the mounting bracket is typically placed on a horizontal surface during use. The base 32 contacts the horizontal surface, and the mounting plate 31 is vertical. The first limiting structure 33 is the mounting structure for hanging the wall-mounted energy meter. The wall-mounted energy meter is hung on the first limiting structure 33 via the hanging ring 12 on its back, thus determining the installation height of the wall-mounted energy meter in the first direction D1. Then, the position of the wall-mounted energy meter in the third direction D3 is determined by the second limiting structure 34. The first direction D1 is the vertical direction. The second direction D2 is the vertical direction in the horizontal direction, which is also the normal direction of the mounting plate 31. The third direction D3 is the horizontal direction in the horizontal direction.

[0060] Compared with related technologies, the mounting bracket for testing wall-mounted energy meters provided in this application includes both a first limiting structure 33 for determining the installation height of the wall-mounted energy meter in the first direction D1 and a second limiting structure 34 for determining the position of the wall-mounted energy meter in the third direction D3. Thus, when the wall-mounted energy meter encounters vibration during testing, even if there is a gap in the fit between the wall-mounted energy meter and the first limiting structure 33, the presence of the second limiting structure 34 can prevent the wall-mounted energy meter from swinging around the mounting point in the third direction D3, thereby making the position of the wall-mounted energy meter more stable, the position of the pulse lamp 11 more stable, and improving the accuracy of data acquisition.

[0061] On the other hand, since the position of the wall-mounted energy meter is relatively stable during the testing process, there is no need to adjust the position of the wall-mounted energy meter, thus saving manpower and helping to improve testing efficiency.

[0062] Please continue to refer to this. Figure 4 In some embodiments of this application, the first limiting structure 33 includes multiple installation stations 331, each of which can be used to hang a wall-mounted energy meter, and the multiple installation stations 331 are arranged along the first direction D1.

[0063] For details, please refer to Figure 1 Wall-mounted energy meters come in different models, each with different dimensions and the position of the pulse lamp 11. When testing the performance of a wall-mounted energy meter, the pulse lamp 11 must be aligned with the sampling port of the photoelectric sampler to ensure accurate sampling.

[0064] Please continue to refer to this. Figure 4 The first limiting structure 33 includes multiple installation stations 331 arranged along the first direction D1, and a wall-mounted energy meter can be hung at each installation station 331. Thus, the installation station 331 of the wall-mounted energy meter can be determined according to the specifications of the meter to be tested. In this way, the same mounting bracket can be used for testing and installing wall-mounted energy meters of various specifications, helping to reduce the testing cost of wall-mounted energy meters.

[0065] Please continue to refer to this. Figure 4 In some embodiments of this application, there is a gap between two adjacent installation stations 331, and a first limiting hole is provided at each installation station 331.

[0066] The first limiting structure 33 also includes a hanging post 332, which can be detachably connected to any of the first limiting holes, and one end of the hanging post 332 protrudes from the first limiting hole for hanging a wall-mounted energy meter.

[0067] Specifically, there is a gap between two adjacent installation stations 331, and each installation station 331 is provided with a first limiting hole. Thus, the multiple first limiting holes are independent of each other. Therefore, when the wall-mounted energy meter is attached to the mounting plate 31, even in a vibration environment, the wall-mounted energy meter will not move from one installation station 331 to another. This helps improve the positional accuracy of the wall-mounted energy meter in the first direction D1, thereby improving the accuracy of data acquisition.

[0068] It should be noted that in this application, the main function of the first limiting hole is to install the mounting post 332. Therefore, the first limiting hole can be a blind hole or a through hole, and can be a smooth hole or a threaded hole. Correspondingly, the mounting post 332 can be a smooth post without threads, which is inserted into the smooth hole. The mounting post 332 can also be a threaded stud, which is threadedly connected to the threaded hole.

[0069] Please continue to refer to this. Figure 3 In some embodiments of this application, the first limiting hole is a screw hole that penetrates the mounting plate 31 along the second direction D2, and the hanging post 332 is a screw. This structure is easy to implement and simple to operate.

[0070] Figure 6 For the screw-type mounting post provided in the embodiments of this application, please refer to... Figure 6 In one embodiment of this application, the mounting post 332 includes a head 3321, a neck 3322, a shoulder 3323 and a screw 3324 connected in sequence, wherein the neck 3322 has the smallest radial dimension and the shoulder 3323 has the largest radial dimension.

[0071] Please combine Figure 2 , Figure 4 , Figure 5 and Figure 6 In use, the mounting post 332 of this structure has its screw portion 3324 threadedly connected to the first limiting hole, with the head 3321, neck 3322, and shoulder 3323 protruding outside the first limiting hole. The shoulder 3323 is used for positioning the mounting post 332 in the second direction D2, and the neck 3322 is used to mate with the hanging ring 12 of the wall-mounted energy meter. This structure allows for easy and accurate positioning and installation of the mounting post 332 on the mounting plate 31, making it convenient to use.

[0072] In addition, the screw part 3324 may also be provided with an anti-loosening nut 333 to strengthen the reliable connection between the hanging post 332 and the mounting plate 31.

[0073] Please continue to refer to this. Figure 4In some embodiments of this application, the second limiting structure 34 includes two movable adjusting members 341 along a third direction D3. The two movable adjusting members 341 can move towards each other or away from each other, and the two movable adjusting members 341 are located on opposite sides of the first limiting structure 33.

[0074] Specifically, as mentioned above, the second limiting structure 34 is used to determine the position of the wall-mounted energy meter on the third direction D3. Movable adjusting members 341 are provided on opposite sides of the first limiting structure 33 along the third direction D3. Thus, during the installation of the wall-mounted energy meter, the distance between the two movable adjusting members 341 can be adjusted so that the two movable adjusting members 341 can be adapted to the dimensions of the wall-mounted energy meter on the third direction D3, thereby better limiting the wall-mounted energy meter on the third direction D3 and preventing the wall-mounted energy meter from shaking on the third direction D3.

[0075] Understandably, there are many ways to implement the movable adjustment component 341, such as the slider in the slide rail and slider structure, or the spring in the spring clamping adaptive structure.

[0076] The specific design of the slide rail and slider structure is as follows: A slide rail (such as a T-slot or linear guide) extending along the third direction D3 is provided on the mounting plate 31. Two sliders are provided on the slide rail, and the distance between them can be adjusted by moving the two sliders. The sliders can be fixed to the slide rail by set screws.

[0077] The specific solution for the spring clamping adaptive structure is as follows: spring-loaded limit blocks (such as compression springs or disc springs) are set on the left and right sides of the mounting plate 31. When the wall-mounted energy meter is inserted, the spring is compressed and automatically clamps the meter body.

[0078] Figure 7 This is a structural schematic diagram of a movable adjustable member provided in an embodiment of this application. Please refer to it. Figure 4 , Figure 5 and Figure 7 In one embodiment of this application, the second limiting structure 34 includes two second limiting holes 342, which correspond one-to-one with two movable adjusting members 341.

[0079] The second limiting hole 342 is a straight hole extending along the third direction D3 and penetrating the mounting plate 31 along the second direction D2.

[0080] The movable adjusting component 341 includes a screw 3411, a retaining ring 3412, and a nut 3413. The screw 3411 is inserted into the second limiting hole 342. The retaining ring 3412 and the nut 3413 are located on both sides of the mounting plate 31, and both can be threadedly connected to the screw 3411 to clamp the mounting plate 31.

[0081] For details, please refer to [link / reference]. Figure 4 , Figure 5 and Figure 7 The second limiting hole 342 is a slotted hole. The movable adjusting component 341 includes a screw 3411, a retaining ring 3412, and a nut 3413. When installing a wall-mounted energy meter, the installation position of the screw 3411 on the third direction D3 of the second limiting hole 342 can be determined according to the size of the wall-mounted energy meter. After determining the position, the retaining ring 3412 and the nut 3413 are rotated to clamp the mounting plate 31. In this way, the position of the movable adjusting component 341 on the mounting plate 31 is fixed, and the distance between the two movable adjusting components 341 along the third direction D3 is determined, which can prevent the wall-mounted energy meter from shaking along the third direction D3.

[0082] As mentioned above, there are many ways to implement the movable adjustment component 341. The movable adjustment component 341 is formed by combining screws 3411, retaining rings 3412 and nuts 3413, and then combined with a slotted hole to form a second limiting structure 34. The second limiting structure 34 has the characteristics of simple composition and easy implementation.

[0083] Please combine Figure 4 and Figure 5 In some embodiments of this application, the base 32 includes a base plate 321 and a plurality of triangular support plates 322. The base plate 321 is perpendicular to the mounting plate 31 and fixed to the bottom of the mounting plate 31. Along the second direction D2, the plurality of triangular support plates 322 are symmetrically arranged on opposite sides of the mounting plate 31 and are fixedly connected to the mounting plate 31 and the base plate 321.

[0084] Specifically, the base 32 includes a base plate 321 and multiple triangular support plates 322. The multiple triangular support plates 322 are symmetrically arranged on opposite sides of the mounting plate 31 and are fixedly connected to the mounting plate 31 and the base plate 321. Thus, multiple triangular support structures are formed between the multiple triangular support plates 322, the base plate 321, and the mounting plate 31, enhancing the stability of the base 32 and the mounting bracket. During the performance testing of the wall-mounted energy meter, the mounting bracket is less likely to tip over when encountering vibration, which helps the test proceed smoothly.

[0085] Please continue to refer to this. Figure 4 and Figure 5 In some embodiments of this application, a rubber pad 323 is also provided on the side of the base plate 321 away from the mounting plate 31.

[0086] Specifically, when testing the performance of wall-mounted energy meters, it is sometimes necessary to place the wall-mounted energy meter with a mounting bracket in a high and low temperature chamber in order to obtain performance test data of the wall-mounted energy meter at different temperatures.

[0087] During the alternation of high and low temperatures, moisture easily accumulates in the high and low temperature chamber. Furthermore, the walls of the chamber are relatively smooth, and air circulates within it. Due to these factors, the mounting brackets are prone to sliding within the chamber, thus deviating from their intended position.

[0088] This application provides a rubber pad 323 on the side of the base plate 321 away from the mounting plate 31, which helps to increase the anti-slip properties of the mounting bracket, prevent the mounting bracket from deviating from the predetermined position, and thus improve the accuracy of sampling.

[0089] Please continue to refer to this. Figure 4 In some embodiments of this application, the base 32 and mounting plate 31 are made of bakelite. Specifically, the wall-mounted energy meter is energized during testing, and the bakelite material of the base 32 and mounting plate 31 helps maintain the insulation between the mounting bracket and the wall-mounted energy meter, improving test accuracy. Furthermore, bakelite has a relatively high density among insulating materials, which helps increase the overall mass of the mounting bracket. Greater mass results in better stability and reduces the likelihood of tilting, which also contributes to improved sampling accuracy.
