Description

Technical Field

[0001] This application relates to the technical field of power monitoring, and in particular, to a monitoring device for the operation of a power operation system. Background Art

[0002] The power monitor is a digital multi-functional network power monitoring device designed for the power monitoring requirements of power systems, industrial and mining enterprises, public facilities, and intelligent buildings. It is manufactured using a high-performance microprocessor with a 16-bit SOC and SMT surface mount production technology, and has the characteristics of high-speed data processing, high precision, and low power consumption. Its main functions include real-time measurement of grid parameters, metering of active and reactive electric energy, output of electric energy pulses, 485 and infrared communications, etc.

[0003] There are various power monitoring devices, among which the on-line power quality monitor is more common. This device is connected to the circuit and system and can monitor the power quality in real time. Due to its particularity, its internal parts need to be maintained at regular intervals to prevent accidents. When traditional equipment is overhauled, multiple small screws need to be disassembled, which not only consumes disassembly time but also makes it inconvenient for the device to be quickly overhauled, which is rather inconvenient.

Detailed Description of the Embodiment

[0019] The following further describes the present application in detail with reference to the attached Figure 1 -drawings.

[0020] The embodiment of the present application discloses a monitoring device for the operation of a power operation system. Refer to Figure 1- A monitoring device for the operation of a power operation system, comprising a power quality monitor body 1 and a protective housing 3. A plurality of insertion holes 13 having the same size as the positioning holes 10 are formed on the protective housing 3. An installation frame plate 2 is fixed on the power quality monitor body 1. A plurality of extension plates 4 are fixed on the installation frame plate 2. Positioning holes 10 adapted to the insertion heads 8 are formed on the extension plates 4. The plurality of extension plates 4 are symmetrically distributed; the outer surface of the protective housing 3 is fitted with the inner surface of the installation frame plate 2; further comprising a locking mechanism. The two locking mechanisms are symmetrically distributed and are installed on the installation frame plate 2 for connecting and fixing the protective housing 3 and the installation frame plate 2.

[0021] In this embodiment, as Figure 2 and Figure 3 shown, the locking mechanism includes a bidirectional lead screw 6 rotatably connected to both sides of the installation frame plate 2. One end of the bidirectional lead screw 6 extends to the outside of the installation frame plate 2 and is fixed with a hand-twisting knob 9. A pair of screwed plates 7 are threadedly connected to the bidirectional lead screw 6. The two screwed plates 7 can approach or move away from each other through the bidirectional lead screw 6. Insertion heads 8 are fixed on the opposite surfaces of the two screwed plates 7. A pair of guide rods 5 are fixed on the installation frame plate 2. The two guide rods 5 are respectively arranged corresponding to the bidirectional lead screw 6 and slidably penetrate through the two screwed plates 7 on the same side as the guide rods 5. During installation, the two hand-twisting knobs 9 are respectively rotated counterclockwise. The two screwed plates 7 on the bidirectional lead screw 6 are respectively driven to approach each other. When the screwed plates 7 reach the appropriate positions, the protective housing 3 is embedded on the installation frame plate 2. After stable connection, at this time, the insertion heads 8, the positioning holes 10 and the insertion holes 13 are in the same straight line. The hand-twisting knobs 9 are rotated clockwise to make the screwed plates 7 move away from each other. When it is observed that the insertion heads 8 extend out of the positioning holes 10, the operation can be stopped, and the installation is completed. For disassembly, only the hand-twisting knobs 9 need to be rotated counterclockwise. The operation is simple, convenient and fast.

[0022] In this embodiment, as Figure 2 and Figure 3 shown, on the side of the extension plate 4 facing the insertion head 8 and at the edge of the positioning hole 10, a chamfer portion 11 is provided. This setting facilitates reducing the friction force, making the insertion of the insertion head 8 smoother and more convenient.

[0023] In this embodiment, as Figure 2 and Figure 3 shown, a plurality of U-shaped holes 12 are formed on the protective housing 3. The guide rods 5 and the bidirectional lead screw 6 pass through the U-shaped holes 12. The U-shaped holes 12 ensure the smooth installation of the protective housing 3 and its embedding into the installation frame plate 2.

[0024] The implementation principle of a monitoring device for power operation system operation in an embodiment of this application is as follows: During installation, rotate two hand-twist knobs 9 counterclockwise respectively. Through the rotation of the bidirectional lead screw 6, drive the two rotary connection plates 7 thereon to approach each other respectively. When the rotary connection plate 7 reaches the appropriate position, embed the protective housing 3 on the installation frame plate 2. After stable connection, at this time, the insertion head 8, the positioning hole 10, and the insertion hole 13 are on the same straight line. Rotate the hand-twist knob 9 clockwise to make the rotary connection plates 7 move away from each other. Stop when it is observed that the insertion head 8 extends out of the positioning hole 10, and the installation can be completed. For disassembly, just rotate the hand-twist knob 9 counterclockwise. The operation is simple, convenient, and fast.

[0025] By setting the installation frame plate 2, the extension plate 4, the guide rod 5, the bidirectional lead screw 6, the rotary connection plate 7, the insertion head 8, the hand-twist knob 9, the positioning hole 10, the chamfered part 11, the U-shaped hole 12, and the insertion hole 13, during maintenance, the staff only needs to rotate two hand-twist knobs 9. When the insertion head 8 is far away from the insertion hole 13, the locking connection between the power quality monitor body 1 and the protective housing 3 can be released, thus avoiding the operation of disassembling multiple screws in the traditional way, further saving the time consumed in the disassembly steps during maintenance, and improving the practicability.
