[0037] Embodiment 1

[0038] Existing measurement and control instruments have a large number of internal modules, such as communication modules, calculation modules, execution modules, etc., which leads to many inconveniences during installation, and are prone to mutual interference, and subsequent maintenance is also very troublesome.

[0039] In order to solve the above problems, it is convenient to install the internal modules and to carry out maintenance, such as Figure 1-Figure 8 As shown, the present invention provides a comprehensive power measurement and control instrument, which comprises a housing 1, a dustproof plate 3, a heat dissipation component, a plurality of plug-in supports 4 and a power measurement and control module.

[0040] Among them, the shell 1 has a hollow accommodating cavity, and an exhaust support 2 is arranged on one side of the shell 1; the dustproof plate 3 is detachably arranged at the top of the shell 1, and an air inlet 31 connected with the accommodating cavity is opened on the dustproof plate 3; the heat dissipation component is arranged on the shell 1, and is used to discharge the hot air in the accommodating cavity; a plurality of plug-in supports 4 are arranged at intervals in the accommodating cavity; the power measurement and control module is located in the accommodating cavity and is arranged on the plug-in support 4.

[0041] Specifically, the dustproof plate 3 is inserted on the housing 1. When the power measurement and control module needs to be repaired, the dustproof plate 3 only needs to be pulled out. After the repair is completed, the dustproof plate 3 is inserted into the housing 1. The above arrangement facilitates the installation and removal of the dustproof plate 3.

[0042] Furthermore, a filter screen 32 is fixedly provided on the dustproof plate 3, and the filter screen 32 is located at the air inlet 31. By providing the filter screen 32, impurities with larger diameters in the air can be filtered out, thereby ensuring the cleanliness of the air entering the accommodating cavity, preventing impurities in the air from affecting the operation of the power measurement and control module, and avoiding short circuits.

[0043] During maintenance, maintenance can be performed by removing the dust cover 3. The plug-in support 4 is arranged in the accommodating cavity at intervals, so that the installed power measurement and control modules do not interfere with each other, and are easy to install and facilitate subsequent maintenance operations.

[0044] Furthermore, the plug-in support 4 includes a mounting frame, a first plug-in component 44 and a second plug-in component. The mounting frame is arranged in the accommodating cavity and is connected to the housing 1. The first plug-in component 44 and the second plug-in component are arranged on the mounting frame at intervals, and the power measurement and control module is arranged between the first plug-in component 44 and the second plug-in component. Specifically, a mounting plate is arranged at the lower end of the housing 1, and the plug-in support 4 is arranged on the mounting plate, and the mounting plate plays a supporting role. The above arrangement facilitates the installation of the power measurement and control module. Moreover, different power measurement and control modules (such as communication modules, operation modules, execution modules, etc.) are correspondingly arranged in different plug-in supports 4. Since the plug-in supports 4 are arranged at intervals, different power measurement and control modules do not affect each other.

[0045] Furthermore, the mounting frame includes a base 41, a top seat 42 and a connecting rod 43 which are arranged at intervals. The base 41 is fixedly arranged on the housing 1, the top seat 42 is arranged opposite to the base 41, the connecting rod 43 is passed through the top seat 42 and connected to the base 41, and the first plug-in assembly 44 and the second plug-in assembly are both arranged on the top seat 42. Specifically, two threaded holes 411 are provided on the base 41, and two groups of connecting rods 43 are provided. Both connecting rods 43 pass through the threaded holes 411 of the top seat 42 and are screwed to the base 41. In order to ensure the smoothness of rotating the connecting rod 43, a bearing is provided on the top seat 42, and the connecting rod 43 is passed through the bearing. In order to avoid hand slippage when rotating the connecting rod 43, an anti-slip pattern is provided on the end of the connecting rod 43 extending from the upper end of the top seat 42.

[0046] Furthermore, a position adjustment structure 7 is provided on one side of the top seat 42 facing the base 41, and the second plug-in component is fixedly provided on the position adjustment structure 7, and the relative distance between the second plug-in component and the first plug-in component 44 can be adjusted by the position adjustment structure 7. By providing the position adjustment structure 7, the size of the circuit board of different power measurement and control modules can be adjusted within a certain range, so that the first plug-in component 44 and the second plug-in component meet the installation requirements of the power measurement and control module.

[0047] Furthermore, the position adjustment structure 7 includes a slider 71 and a locking member 72. A slide groove 421 is provided on one side of the top seat 42 facing the base 41. The slider 71 is slidably arranged in the slide groove 421. The locking member 72 is used to lock the position of the slider 71 in the slide groove 421. The second plug-in component is arranged on the slider 71. When installing the circuit board of the power measurement and control module, by adjusting the position of the slider 71 in the slide groove 421, it is ensured that the circuit board can be arranged between the first plug-in component 44 and the second plug-in component. After adjusting the position, the position of the slider 71 can be locked by using the locking member 72. Through the above arrangement, the adaptability of installing power measurement and control modules of different sizes can be improved.

[0048] Further, the first plug-in assembly 44 includes a clamping rod 441, a connector 442 and a positioning member 443. The clamping rod 441 is fixedly arranged on the top seat 42 of the mounting frame, the connector 442 is arranged on the clamping rod 441, and the positioning member 443 is arranged on the connector 442. The circuit board of the power measurement and control module can be inserted on the connector 442, and the positioning member 443 is used to lock the circuit board on the connector 442. The circuit board is fixed on the clamping rod 441 by the positioning member 443, which is convenient for the installation of the circuit board. When the circuit board needs to be repaired later, it is only necessary to remove the positioning member 443 from the connector 442. In this embodiment, the positioning member 443 is screwed with the connector 442, and one end of the circuit board of the power measurement and control module is inserted on the connector 442, and the positioning member 443 is screwed so that the positioning member 443 passes through the mounting hole of the circuit board, thereby realizing the installation and positioning of the circuit board.

[0049] Furthermore, a guide groove is provided on the clamping rod 441 along the extension direction of the clamping rod 441, and the connecting member 442 is slidably arranged in the guide groove. By providing the guide groove, the position of the connecting member 442 can be adjusted according to the position of the mounting hole provided on the circuit board, so as to adapt to the installation of the circuit board of different power measurement and control modules.

[0050] Furthermore, in order to improve the strength of fixing the circuit board, a plurality of connectors 442 are slidably arranged in the guide groove. The plurality of connectors 442 can be connected to the plurality of mounting holes on the circuit board in a one-to-one correspondence, thereby ensuring the strength of the circuit board installation.

[0051] Furthermore, a positioning groove 4411 is provided on the side of the clamping rod 441 facing the second plug-in assembly along the extension direction of the clamping rod 441. By providing the positioning groove 4411, the circuit board can be positioned, thereby further improving the stability of the circuit board installation. In this embodiment, in order to prevent the positioning groove 4411 from scratching the circuit board, a rubber layer is provided on the surface of the positioning groove 4411. In order to prevent the first plug-in assembly 44 and the second plug-in assembly from causing a short circuit in the circuit board, in this embodiment, the first plug-in assembly 44 and the second plug-in assembly are both made of plastic.

[0052] Furthermore, in this embodiment, the structure of the second plug-in component is the same as the structure of the first plug-in component 44, and will not be described in detail herein.

[0053] Furthermore, the exhaust support 2 includes a grid plate 21 and a mounting foot plate 22 which are connected to each other. The grid plate 21 can play a role in exhausting gas, and the integrated power measurement and control instrument is used for installing the mounting foot plate 22 .

[0054] When in use, first install the power measurement and control module inside the power measurement and control instrument, such as the communication module, the operation module, the execution module, etc. Rotate the connecting rod 43 to make the top seat 42 of the plug-in support 4 detach from the base 41, then place one side of the power measurement and control module in the connecting piece 442 of the fixed clamping rod 441, the connecting piece 442 slides inside the guide groove, adjust the connecting piece 442 to correspond to the position of the mounting hole on the circuit board, then insert the positioning piece 443 into the connecting piece 442 to complete the fixation of one side, and at the same time, the positioning groove 4411 on the clamping rod 441 can protect the side of the circuit board. Then adjust the relative distance between the second plug-in component and the first plug-in component 44, and then fix the other side of the circuit board that is not locked in the same way as above. After all the power measurement and control modules are installed, connect the internal circuits in sequence, and finally install the connecting rod 43 on the base 41. After the electric power measurement and control module is fully assembled, the measurement and control instrument can be installed through the mounting foot plate 22 on the exhaust support 2 and can be used.

[0055] During use, the hot air inside the shell 1 is discharged from the air outlet through the heat dissipation fan 5, and then discharged to the outside through the through holes on the grid plate 21, while the cold air outside enters the inside of the shell 1 from the air inlet 31 after being filtered through the filter 32, thereby completing the air circulation and achieving the cooling effect; when maintenance is required, the dustproof plate 3 is slid to the side and taken out, and the module on the single plug-in support 4 can be inspected, which is more convenient to use.

[0056] In summary, the present invention completes the assembly of various modules by setting a plurality of plug-in supports 4 inside the housing 1, so that the modules are spaced apart, which is convenient for subsequent maintenance and wiring, and avoids interference between each other. At the same time, the module assembly is completed by the connector 442 on the clamping rod 441, which can adapt to modules of different sizes, making assembly more convenient and having wide applicability. In addition, the heat dissipation inside the housing 1 is effectively treated during use to ensure the normal operation of the instrument; at the same time, the dustproof plate 3 can be opened during maintenance to inspect or disassemble the module on a single plug-in support 4, which is conducive to later maintenance work.
