Description

Technical Field

[0001] This utility model belongs to the technical field of primary frequency modulation online monitoring devices, and more specifically, it relates to an installation mechanism for a primary frequency modulation online monitoring device. Background Technology

[0002] The primary frequency regulation online monitoring device is a real-time monitoring equipment developed for the primary frequency regulation function of power systems. By deploying high-precision sensors and data acquisition modules, it collects key parameters such as unit power, speed, and grid frequency in real time. After signal filtering, data calibration, and frequency regulation performance index calculation by the embedded processing unit, it can dynamically evaluate the core performance of the unit's primary frequency regulation response speed, regulation accuracy, and stability. It has functions such as abnormal state early warning, historical data tracing, and report generation. It supports real-time communication with the grid dispatching system, providing data support for power system primary frequency regulation performance optimization, equipment operation status assessment, and grid frequency stability analysis. It is suitable for online monitoring scenarios of various types of power generation equipment such as thermal power units, hydropower units, and wind power units.

[0003] In the prior art, primary frequency regulation online monitoring devices are usually installed in the main control room of the power generation equipment, near the electrical control cabinet, or in a stable area close to the sensor acquisition point to facilitate data acquisition and transmission. When installing and fixing, first select a flat wall or cabinet, use expansion bolts and screws to firmly fix the mounting bracket of the device, and then insert the main body of the device into the bracket slot and tighten the fixing screws.

[0004] However, existing online monitoring devices for primary frequency modulation require frequent maintenance during use. The screw fixing method used in these devices necessitates repeated disassembly and reassembly, making the process cumbersome and time-consuming. Furthermore, the screws are prone to stripping and thread wear after repeated disassembly and reassembly. This not only increases the workload of maintenance personnel but also directly affects the efficiency and long-term reliability of equipment maintenance. Utility Model Content

[0005] In view of the problem that the screw fixing method in the relevant technology requires repeated disassembly during equipment maintenance, which is cumbersome and time-consuming, increases the workload of maintenance personnel, and directly affects the maintenance efficiency and long-term reliability of equipment, this utility model proposes an installation mechanism for a primary frequency modulation online monitoring device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an installation mechanism for a primary frequency modulation online monitoring device, including a mounting frame. The surface of the mounting frame is provided with an elastic driving mechanism. The placement end of the elastic driving mechanism is provided with a monitoring device body. The driving end of the elastic driving mechanism is provided with a clamping and limiting mechanism. The clamping and limiting mechanism is provided with a pressing and opening mechanism inside. The mounting frame is provided with a wire-passing mechanism inside.

[0008] By pressing the monitoring device body, the elastic drive mechanism is displaced, so that the drive end of the elastic drive mechanism drives the clamping and limiting mechanism to close, so that the clamping end of the clamping and limiting mechanism clamps and limits the monitoring device body.

[0009] Furthermore, the elastic drive mechanism includes a placement plate, one end of which is fixedly connected to a sliding rod, which is slidably connected within a mounting frame.

[0010] Furthermore, the clamping and limiting mechanism includes a connecting rod, one end of which is rotatably connected to the inside of the base plate, and the other end of which is rotatably connected to a sliding frame. The sliding frame is slidably connected to the inside of the mounting frame, one end of which is fixedly connected to a clamping plate, and a fixing column is slidably connected inside the clamping plate.

[0011] Furthermore, a fixing plate is fixedly installed on the surface of the monitoring device body. The fixing plate has a first fixing hole and a second fixing hole.

The angled end of the pressure column is slidably connected inside the extrusion groove. A pressing plate is slidably connected to the pressure column and is fixedly connected to it. The pressing plate is slidably connected to the surface of the card plate.

[0013] Furthermore, the wire guiding mechanism includes a plurality of first rotating rods, all of which are rotatably connected inside the mounting frame. A wire guiding hole is provided at the bottom of the mounting frame, and a second rotating rod is rotatably connected inside the wire guiding hole.

[0014] Furthermore, several partitions are slidably connected to the surface of the second rotating rod, and anti-wear pads are fixedly connected to the surfaces of both the first and second rotating rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a pressing mechanism to drive the elastic drive body of the monitoring device to move, so that the driving end of the elastic drive mechanism drives the clamping and limiting mechanism to close, thereby clamping and limiting the monitoring device body.

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is an installation mechanism for a primary frequency modulation online monitoring device, including a mounting frame 1. An elastic drive mechanism 3 is provided on the surface of the mounting frame 1. A monitoring device body 2 is provided at the placement end of the elastic drive mechanism 3. A clamping and limiting mechanism 4 is provided at the driving end of the elastic drive mechanism 3. A pressing and opening mechanism 5 is provided inside the clamping and limiting mechanism 4. A wire-passing mechanism 6 is provided inside the mounting frame 1.

[0031] By pressing the monitoring device body 2, the elastic drive mechanism 3 is driven to move, so that the drive end of the elastic drive mechanism 3 drives the clamping and limiting mechanism 4 to close, so that the clamping end of the clamping and limiting mechanism 4 clamps and limits the monitoring device body 2.

[0032] By fixing the mounting bracket 1 inside the cabinet, the monitoring device body 2 is placed at the placement end of the elastic drive mechanism 3. Pressing the monitoring device body 2 drives the elastic drive mechanism 3 to move, so that the driving end of the elastic drive mechanism 3 drives the clamping and limiting mechanism 4 to close, so that the clamping end of the clamping and limiting mechanism 4 clamps and limits the monitoring device body 2. When disassembling, the pressing and opening mechanism 5 is driven, so that the pressing and opening mechanism 5 drives the clamping end of the clamping and limiting mechanism 4 to unfold, thereby releasing the monitoring device body 2 and completing the disassembly. The wire passing mechanism 6 facilitates the separation of the connecting wires of the monitoring device body 2 to prevent the connecting wires from getting tangled.

[0033] By pressing the monitoring device body 2, the elastic drive mechanism 3 is displaced, so that the drive end of the elastic drive mechanism 3 drives the clamping and limiting mechanism 4 to close, so that the clamping end of the clamping and limiting mechanism 4 clamps and limits the monitoring device body 2. When disassembling, the press opening and closing mechanism 5 is driven, so that the press opening and closing mechanism 5 drives the clamping end of the clamping and limiting mechanism 4 to unfold. This design realizes the quick insertion and removal replacement of the monitoring device body 2 through a split press trigger mechanism, which solves the problems of repeated disassembly and cumbersome process and easy stripping and wear of screws caused by traditional screw fixing methods, significantly reducing maintenance intensity and improving long-term reliability.

[0034] In addition, in specific applications, the monitoring equipment body 2 is a primary frequency regulation online monitoring device. Its working principle is to collect the grid frequency signal and the active power data of the unit in real time. By calculating the dynamic response relationship between frequency deviation and power change, it can determine whether the unit adjusts its output in a timely manner according to the preset droop rate based on the characteristics of the speed regulation system when the grid frequency fluctuates. This allows for the evaluation of the response speed, regulation accuracy and contribution of the primary frequency regulation action, ensuring that the unit meets the grid frequency regulation performance requirements.

[0035] In one embodiment, the elastic drive mechanism 3 includes a placement plate 301, a sliding rod 302 fixedly connected to one end of the placement plate 301, the sliding rod 302 being slidably connected within the mounting frame 1, a base plate 303 fixedly connected to one end of the sliding rod 302, a spring 304 sleeved on the surface of the sliding rod 302, one end of the spring 304 being fixedly connected to one end of the placement plate 301, and the other end of the spring 304 being fixedly connected to the surface of the mounting frame 1, with the monitoring device body 2 placed on the surface of the placement plate 301.

[0036] By fixing the mounting bracket 1 inside the cabinet, the monitoring device body 2 is placed on the surface of the placement plate 301, causing the monitoring device body 2 to press against the placement plate 301. The placement plate 301 drives the sliding rod 302 to slide inside the mounting bracket 1. At the same time, the placement plate 301 compresses the spring 304, causing the sliding rod 302 to drive the base plate 303 to move synchronously.

[0037] In one embodiment, the clamping and limiting mechanism 4 includes a connecting rod 401. One end of the connecting rod 401 is rotatably connected to the inside of the base plate 303, and the other end of the connecting rod 401 is rotatably connected to a sliding frame 402. The sliding frame 402 is slidably connected to the inside of the mounting frame 1. One end of the sliding frame 402 is fixedly connected to a clamping plate 403. A fixing post 404 is slidably connected inside the clamping plate 403. A fixing plate 405 is fixedly installed on the surface of the monitoring device body 2. A first fixing hole 406 and a second fixing hole 407 are opened on the surface of the fixing plate 405. The fixing post 404 is engaged in the first fixing hole 406. One end of the fixing post 404 is fixedly connected to a second spring 408. One end of the second spring 408 is fixedly connected to the inside of the clamping plate 403.

[0038] When the base plate 303 moves, it moves one end of the connecting rod 401, causing the other end of the connecting rod 401 to slide the sliding frame 402 inside the mounting frame 1. This causes the sliding frame 402 to move the clamping plate 403, and simultaneously, the clamping plate 403 causes the fixing post 404 to contact the surface of the fixing plate 405. When the fixing plate 405 is located in the first fixing hole 406, the spring 408 causes the fixing post 404 to engage in the first fixing hole 406, thus fixing the fixing plate 405 and securing the monitoring device body 2. When it is necessary to move the monitoring device... When the device body 2 is installed on the wall, the mounting bracket 1 is fixedly installed on the wall, and the monitoring device body 2 is pressed against the surface of the placement plate 301 by the fixing plate 405. This causes the sliding rod 302, the base plate 303, the connecting rod 401, and the sliding bracket 402 to drive the clamping plate 403 to contact the fixing post 404 with the surface of the fixing plate 405. When the fixing plate 405 is located at the second fixing hole 407, the spring 408 drives the fixing post 404 to engage in the second fixing hole 407, thus fixing the fixing plate 405 and fixing the monitoring device body 2.

[0039] In one embodiment, the pressing and opening mechanism 5 includes a pressing column 501, which is slidably connected inside the card plate 403. A sliding plate 502 is fixedly connected to one end of a fixed column 404, and a moving block 503 is fixedly connected to one end of the sliding plate 502. The moving block 503 is slidably connected inside the card plate 403, and a squeezing groove 504 is provided inside the moving block 503. The angled end of the pressing column 501 is slidably connected inside the squeezing groove 504. The pressing column 501 is movably and fixedly connected to a pressing plate 505, which is slidably connected to the surface of the card plate 403.

[0040] By pressing the button plate 505, the button plate 505 drives the pressure column 501 to slide, so that the angled end of the pressure column 501 is slidably connected in the extrusion groove 504. Through the continuous movement of the pressure column 501, the pressure column 501 drives the moving block 503 to slide through the extrusion groove 504, so that the moving block 503 drives the sliding plate 502 to move, thereby driving the fixed column 404 to compress the second spring 408, so that the fixed column 404 is disengaged from the first fixed hole 406 or the second fixed hole 407. Then the monitoring device body 2 can be taken out for easy disassembly.

[0041] In one embodiment, the wire guiding mechanism 6 includes a plurality of first rotating rods 601, all of which are rotatably connected inside the mounting frame 1. A wire guiding hole 603 is provided at the bottom of the mounting frame 1, and a second rotating rod 602 is rotatably connected inside the wire guiding hole 603. A plurality of partitions 604 are slidably connected to the surface of the second rotating rod 602, and anti-wear pads 605 are fixedly connected to the surfaces of the first rotating rods 601 and the second rotating rods 602.

[0042] By passing the connecting wires inside the monitoring device body 2 through the wire hole 603 at the bottom of the mounting bracket 1, along the surface of the first rotating rod 601, and through the second rotating rod 602, and by sliding the partitions 604, the connecting wires inside the monitoring device body 2 are separated according to the thickness of the connecting wires. At the same time, the anti-wear pads 605 can prevent the surface of the connecting wires from being broken by friction, making it convenient to separate the connecting wires and prevent them from getting tangled.

[0043] Through the above technical solution, 1. By fixing the mounting bracket 1 inside the cabinet, the monitoring device body 2 is placed on the surface of the placement plate 301, causing the monitoring device body 2 to press against the placement plate 301. The placement plate 301 drives the sliding rod 302 to slide inside the mounting bracket 1. At the same time, the placement plate 301 compresses the first spring 304, causing the sliding rod 302 to drive the base plate 303 to move synchronously. When the base plate 303 moves, it drives one end of the connecting rod 401 to move, causing the other end of the connecting rod 401 to drive the sliding frame 402 to slide inside the mounting bracket 1. The sliding frame 402 drives the locking plate 403 to move, and at the same time, the locking plate 403 drives the fixing post 404 to contact the surface of the fixing plate 405. When the fixing plate 405 is located in the first fixing hole 406, the second spring 408 drives the fixing post 404 to engage in the first fixing hole. Within 406, the fixing plate 405 is fixed, thereby fixing the monitoring device body 2. During disassembly, press the pressing plate 505, causing the pressing plate 505 to drive the pressure column 501 to slide, so that the angled end of the pressure column 501 is slidably connected in the extrusion groove 504. Through the continuous movement of the pressure column 501, the pressure column 501 drives the moving block 503 to slide through the extrusion groove 504, causing the moving block 503 to drive the sliding plate 502 to move, thereby causing the fixing column 404 to compress the second spring 408, so that the fixing column 404 is disengaged from the first fixing hole 406 or the second fixing hole 407. Then the monitoring device body 2 is taken out, realizing the quick plugging and unplugging replacement of the monitoring device body 2. This completely solves the problems of repeated disassembly and tediousness and easy stripping and wear of screws caused by the traditional screw fixing method, significantly reducing maintenance intensity and improving long-term reliability.

[0044] 2. By passing the connecting wires of the monitoring device body 2 through the wire hole 603 at the bottom of the mounting bracket 1, along the surface of the first rotating rod 601, and then through the second rotating rod 602, and by using the sliding partition 604 to adaptively adjust the spacing according to the wire diameter, the connecting wires are orderly separated and prevented from tangling; at the same time, the anti-wear pad 605 effectively prevents the surface of the cable from being worn and broken.
