Description

Technical Field

[0001] This utility model belongs to the technical field of oilfield energy auxiliary equipment, and relates to monitoring equipment for oilfield wellhead wind, solar and energy storage microgrids. Background Technology

[0002] Monitoring equipment for wind, solar, and energy storage microgrids is used to monitor the operating status and data of the microgrid. It can remotely control and adjust the operating status of the microgrid, and detect and diagnose potential faults or problems by monitoring and analyzing operating data in real time, and issue alarms to operators to help them take timely measures to prevent faults from occurring. Currently, monitoring equipment for wind, solar, and energy storage microgrids is generally installed inside the control cabinet, which is a relatively complicated installation method. When it is necessary to perform regular inspections on the monitoring equipment, it is necessary to use wrenches or other tools to remove the monitoring equipment from the rails. This operation is time-consuming and affects the work efficiency of operators.

[0003] Chinese patent "A Monitoring Device for Wind, Solar and Energy Storage Microgrids" (Announcement No. CN221900606U, Announcement Date: 2024-10-25) connects to both sides of the inner wall of the control cabinet body through multiple mounting components. When the monitoring device needs to be periodically inspected, the power component is pulled, causing the power component to move the connecting component in the sliding groove opened at the top of the inner wall of the fixed groove. The connecting component drives the limit block to move, so that one end of the limit block moves out of the slot opened at one end of the monitoring device, causing the monitoring device to lose its limit. The monitoring device can then be pulled out from the control cabinet body. This structure allows for quick disassembly of the monitoring device, making it convenient for the operator to inspect it. To a certain extent, it saves the operator's working time and improves the operator's work efficiency.

[0004] However, the monitoring equipment used in the wind, solar and energy storage microgrid requires removal from the control cabinet for each maintenance, and then reinstallation after maintenance. This disassembly is time-consuming and increases maintenance time. Furthermore, the monitoring equipment may fall from the control cabinet and be damaged during this process. Some minor issues do not require removing the monitoring equipment from the control cabinet, thus resulting in defects in the use of the device. Utility Model Content

[0005] The purpose of this utility model is to provide monitoring equipment for oilfield wellhead wind, solar and energy storage microgrids, which solves the problem that in the prior art, the monitoring equipment needs to be removed from the control cabinet for each maintenance and then reinstalled after the maintenance is completed, which is time-consuming and increases maintenance time and cost.

[0006] The technical solution adopted by this utility model is a monitoring device for a microgrid of wind, solar and energy storage at oilfield wellheads, including a control cabinet body. The control cabinet body has two corresponding inner side walls that are symmetrically and fixedly connected with mounting brackets. The two mounting brackets are slidably connected to a horizontally arranged push plate. The push plate slides on the mounting bracket in the direction of extending or retracting into the control cabinet body. The upper surface of the push plate is detachably connected to the monitoring device body.

[0007] The present invention is further characterized in that: Each of the two mounting brackets has a sliding guide rail on one side. The push plate has sliders on both sides of the sliding guide rail. The sliders slide in the sliding guide rail, so that the push plate can slide on the mounting bracket in the direction of extending or retracting into the control cabinet body.

[0008] The bottom of the push plate is also equipped with a limit device, which limits the push plate after it slides to a certain position.

[0009] The limiting device includes racks symmetrically arranged on both sides of the lower surface of the push plate near the mounting bracket. Each rack is meshed with a third gear. The two mounting brackets are rotatably connected to a rotating shaft on the side of the push plate extending into the control cabinet body. The third gear is fixed at the corresponding ends of the rotating shaft. A third connecting plate is also provided on the two mounting brackets below the rotating shaft, corresponding to the rotating shaft. A connecting bracket is also connected below the third connecting plate. The end of the connecting bracket near the rotating shaft passes through the third connecting plate and is fixedly connected to a first connecting plate. The first connecting plate is parallel to the third connecting plate and is located between the third connecting plate and the rotating shaft. A second gear is fixedly connected to both ends of the first connecting plate near the rotating shaft. A first gear is fixedly connected to the rotating shaft at the position corresponding to the second gear. A locking device is also provided at the end of the connecting bracket below the third connecting plate.

[0010] The connecting frame is designed in a "U" shape. The upper two sides of the U-shaped connecting frame are connected to the first connecting plate after passing through the third connecting plate. The two ends of the third connecting plate near the rotating shaft are symmetrically connected to the connecting columns. The connecting columns pass through the first connecting plate near the rotating shaft and are fixed on the connecting columns. The first connecting plate slides on the connecting columns under the push of the connecting frame. A limit plate a is provided at the end of the connecting column near the rotating shaft. A first spring is also provided on the connecting column between the limit plate a and the first connecting plate.

[0011] The positioning device includes locking holes. Multiple locking holes are arranged from top to bottom on the two outer side walls of the connecting frame corresponding to the end of the third connecting plate away from the rotating shaft. A fixing block is also symmetrically fixed on the side of the third connecting plate away from the rotating shaft. Two fixing blocks are respectively set on the two outer side walls of the connecting frame. A locking block is slidably connected in the fixing block. The locking block slides in the direction of the locking hole in the fixing block, and the shape of the end of the locking block near the locking hole is adapted to the locking hole.

[0012] The fixed block has a sliding groove inside, the card block is located in the sliding groove, and the card block is fixedly connected to the upper and lower limit plates symmetrically. The limit plates cooperate with the inner wall of the sliding groove. The two ends of the card block pass through the fixed block. After the side of the card block away from the connecting frame passes through the fixed block, it is fixedly connected to the second connecting plate. The side of the second connecting plate away from the card block is fixedly connected to the pull ring.

[0013] Two limiting plates are fixedly connected to a second spring on the side opposite to the card hole. The other end of the second spring is fixedly connected to the end of the fixing block opposite to the card hole, and the two ends of the same second spring are located on the same side of the card block.

[0014] The bottom of the push plate is rotatably connected to a two-way lead screw. The middle two sides of the push plate are symmetrically arranged with slide grooves a. Fixed plates are slidably arranged in both slide grooves a. The upper end of the fixed plate extends out of the upper surface of the push plate. The bottom of the middle of the fixed plate is fixedly embedded with a lead screw nut. The bottom of the middle of the fixed plate passes through the slide groove a so that the lead screw nut and the two-way lead screw cooperate. The two ends of the two-way lead screw have opposite screw threads. When the two-way lead screw rotates, it drives the two fixed plates to move in a direction that is closer to each other or away from each other.

[0015] A turntable is also fixedly connected to the bidirectional lead screw, and the bidirectional lead screw is rotated by rotating the turntable.

[0016] The beneficial effects of this utility model are: This utility model features a push plate that slides inside the mounting bracket. The push plate moves along the inside of the mounting bracket, and the top of the push plate is detachably connected to the main body of the monitoring equipment. The movement of the push plate moves the main body of the monitoring equipment, making it convenient to push the main body of the monitoring equipment out of the control cabinet for maintenance.

[0017] This utility model achieves the function of fixing the position of the push plate by setting up a mounting bracket, push plate, rack, third gear, rotating shaft, third connecting plate, first gear, second gear, first connecting plate, connecting bracket, locking hole and locking block. After the push plate is moved to a suitable position, the connecting bracket is moved. The connecting bracket moves the first connecting plate and the second gear until one side of the second gear contacts the first gear. The second gear meshes with the first gear, fixing the position of the first gear and preventing the push plate from suddenly moving and affecting the maintenance of the main body of the monitoring equipment.

[0018] This utility model achieves the detachable function of the main body of the monitoring equipment by setting a fixed plate, a two-way lead screw, a turntable and a push plate. When it is necessary to replace the main body of the monitoring equipment or to conduct a more detailed inspection, the turntable is rotated, and the turntable rotates with the two-way lead screw. The rotation of the two-way lead screw moves the fixed plates at both ends, loosening the fixation of the main body of the monitoring equipment, making it easy to remove the main body of the monitoring equipment from the control cabinet.

The two ends of the first connecting plate 13 are slidably connected to the connecting post 14. The first connecting plate 13 moves along the outer side of the connecting post 14. A first spring 15 is provided on the outer side of the connecting post 14. The movement of the first connecting plate 13 compresses the first spring 15, generating elastic force. When the first spring 15 loses its compressive force, it returns to its original position along with the first connecting plate 13 under the action of the elastic force. A second gear 12 is symmetrically fixedly connected to the top of the first connecting plate 13. The movement of the first connecting plate 13 carries the first connecting plate 13 back to its original position.

[0049] Furthermore, a bidirectional lead screw 6 is rotatably connected to the bottom of the push plate 4, and a fixed plate 5 is symmetrically slidably connected to the top of the push plate 4. The bottom of the fixed plate 5 passes through one side of the push plate 4 and is threadedly connected to the bidirectional lead screw 6. The bidirectional lead screw 6 rotates, causing the fixed plates 5 at both ends to move.

[0050] The fixed block 17 has a symmetrical sliding connection to a limiting plate 21. One side of the limiting plate 21 is fixedly connected to the locking block 20. The locking block 20 moves, causing the limiting plate 21 to move as well.

[0051] A second spring 22 is fixedly connected between one side of the limiting plate 21 and the fixing block 17. When the limiting plate 21 moves, it compresses the second spring 22. The second spring 22 generates elastic force when it is compressed. When the second spring 22 loses its compressive force, under the action of the elastic force, the second spring 22, along with the limiting plate 21 and the locking block 20, returns to its original position.

[0052] The end of the card block 20 away from the card hole 19 passes through the side of the fixing block 17 and is fixedly connected to the second connecting plate 18. The second connecting plate 18 moves and moves the card block 20. The side of the control cabinet body 1 away from the card block 20 is fixedly connected to the pull ring 23. The pull ring 23 moves and moves the second connecting plate 18.

[0053] A turntable 7 is fixedly connected to the outside of the bidirectional lead screw 6. Rotating the turntable 7 causes the bidirectional lead screw 6 to rotate.

[0054] In use, pull the pull ring 23 to move the locking block 20 away from the locking hole 19, thus canceling the limit. Then push the connecting frame 16. The connecting frame 16 moves, causing the first connecting plate 13 to move along the connecting post 14 toward the rotating shaft 24. The movement of the first connecting plate 13 compresses the first spring 15. The first connecting plate 13 moves the second gear 12 until one side of the second gear 12 contacts the first gear 11, so that the second gear 12 and the first gear 11 mesh together. Since the second gear 12 will not rotate, the first gear 11 will not rotate either, thus fixing the position of the connecting post 14 and the third gear 9, preventing the push plate 4 from moving out of the mounting frame 3 during use. At this time, the locking block 20 is then inserted into the appropriate locking hole 19 to fix the position of the connecting frame 16.

[0055] When it is necessary to remove the push plate 4, along with the main body 2 of the monitoring equipment, from the control cabinet body 1, pull the pull ring 23. The pull ring 23, through the second connecting plate 18, moves the locking block 20 out of the locking hole 19. At this time, the first spring 15 loses its pressing force. Under the action of the elastic force, the first spring 15 moves the first connecting plate 13 away from the rotating shaft 24, causing the second gear 12 to separate from the first gear 11, releasing the restriction on the first gear 11. Pull the push plate 4 to remove it from the control cabinet body 1. The push plate 4, along with the main body 2 of the monitoring equipment, gradually moves away from the control cabinet body 1. Inside the main body 1 of the control cabinet, it is convenient for staff to inspect and maintain the main body 2 of the monitoring equipment. When the main body 2 of the monitoring equipment needs to be removed from the main body 1 for replacement, the turntable 7 is rotated. The turntable 7 rotates the bidirectional lead screw 6. The bidirectional lead screw 6 rotates and moves the fixing plates 5 at both ends until the fixing plates 5 leave the sides of the main body 2 of the monitoring equipment, releasing the fixing of the main body 2 of the monitoring equipment. The main body 2 of the monitoring equipment can then be removed from the surface of the push plate 4, making it easier to inspect and maintain the main body 2 of the monitoring equipment more carefully, and also making it easier to replace the main body 2 of the monitoring equipment.

[0056] When the push plate 4, along with the main body 2 of the monitoring equipment, is removed from the main body 1 of the control cabinet for maintenance or disassembly, after the push plate 4 is pulled out to a certain position, the second gear 12 can be engaged with the first gear 11 by pushing the connecting frame 16, so that the rotating shaft 24 cannot rotate. Then, the locking block 20 is inserted into the appropriate locking hole 19 to prevent the push plate 4 from sliding during maintenance or disassembly.
