Description

Technical Field

[0001] This invention relates to the field of microcomputer protection technology, specifically to an intelligent microcomputer measurement and control device for high and low voltage distribution cabinets. Background Technology

[0002] Traditional high-voltage switchgear, prefabricated substations and outdoor circuit breakers are mostly in harsh environments. At the same time, existing microcomputer protection and control devices usually contain a dense array of circuit boards such as CPU boards and other functional modules. These boards are fixed inside the housing and connected to each other by wires. Therefore, the wiring inside the housing is complex, and there is a great deal of mutual influence, which makes disassembly, assembly and maintenance very difficult.

[0003] To address this, Chinese patent CN218525969U discloses an automated microcomputer-based integrated protection and control device for substations. This device allows for convenient installation on a frame using mounting components. The main body is placed in a slot on the frame, and a knob is turned to retract the folding rod. The retractable folding rod provides internal support within the slot, creating a fixed internal brace. Compared to the traditional screw-based fixing method, this device allows for tool-free installation and disassembly, improving ease of use. The internal mounting plate and locking components allow for the secure installation of circuit boards of different sizes, enhancing applicability and meeting various usage requirements.

[0045] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0046] Reference Figures 1-3 A smart microcomputer monitoring and control device for high and low voltage distribution cabinets includes a frame 1, a main unit 2, and a fixing device 3. A card holder 11 is installed on the frame 1, and a buckle 21 that cooperates with the card holder 11 is provided on the main unit 2. When the main unit 2 is installed on the frame 1, the buckle 21 and the card holder 11 are slidably engaged. The fixing device 3 includes a limiting component 31, which is installed on the frame 1 and is used to limit the movement of the buckle 21.

[0047] The frame 1 is provided with four card slots 11 and is divided into two groups. The two groups of card slots 11 are located on the upper and lower sides of the frame 1 respectively. The main unit 2 is provided with four buckles 21 that correspond one-to-one with the card slots 11. The main unit 2 is equipped with a visual sensor and an alarm light 23.

[0048] This invention achieves the function of quick assembly and disassembly of the intelligent microcomputer monitoring and control device through a frame 1, a main unit 2, and a fixing device 3, facilitating the operation and maintenance of the equipment by operators. It solves the problem of poor structural stability and easy jamming in traditional microcomputer integrated protection and monitoring and control devices after installation. During installation, the operator first uses bolts to install the frame 1 onto a wall or other fixed component. Then, the buckle 21 of the main unit 2 is aligned with the mounting base 11. Next, the main unit 2 is slid, causing the buckle 21 to slide. After the buckle 21 engages with the mounting base 11, the operator releases the buckle. The mounting base 11 supports the buckle 21, allowing the main unit 2 to be stably installed on the frame 1 under gravity. The limiting component 31 then restricts the sliding of the buckle 21, preventing the main unit 2 from falling off under external force during use, further improving the stability of the main unit 2 installation. Simultaneously, the visual sensor and alarm light 23 enable human body detection and alarm functions, preventing the intelligent microcomputer monitoring and control device from remaining constantly lit, thus giving it advantages such as high intelligence and long lifespan.

[0049] Reference Figures 2-5 The limiting component 31 includes a limiting block 312 and a mounting bracket 313; a guide rail 311 is provided on the frame 1, the limiting block 312 and the mounting bracket 313 are slidably mounted on the guide rail 311, and the limiting bracket is connected to the mounting bracket 313; the fixing device 3 also includes a linear drive component 32, which includes a rotary driver 321 and a screw 322; the rotary driver 321 is mounted on the frame 1; the screw 322 is rotatably mounted on the frame 1, and the screw 322 is threadedly connected to the mounting bracket 313, and the drive end of the rotary driver 321 is connected to the screw 322 in a transmission connection.

[0050] There are two guide rails 311, four limit blocks 312 and mounting brackets 313, and two screws 322. Each screw 322 has two threaded sections with opposite helical directions. The four mounting brackets 313 are threadedly connected to the four threaded sections of the two screws 322 respectively. Each screw 322 is fitted with a sleeve 326. The two sleeves 326 are connected by a synchronous belt 327. One screw 322 and the drive end of the rotary driver 321 are respectively fitted with a bevel gear 325. The two bevel gears 325 are connected by a drive.

[0051] This invention utilizes a guide rail 311, a limiting block 312, a mounting bracket 313, a rotary driver 321, and a screw 322 to restrict the movement of the latch 21 after it engages with the mounting base 11, thereby improving the installation stability of the main unit 2. The rotary driver 321 is preferably a servo motor, electrically connected to the controller. When installing the main unit 2, the operator first aligns the latch 21 with the mounting base 11, then slides the main unit 2, causing the latch 21 to slide. After the latch 21 engages with the mounting base 11, the operator releases the latch. The mounting base 11 supports the latch 21, allowing the main unit 2 to be stably mounted on the frame 1 under gravity. The controller then sends a signal to the rotary driver 321, which drives the screw 322 to rotate via a bevel gear 325. The screw 322 drives the mounting bracket 313, which is threadedly connected to it, to move. The mounting bracket 313 drives the limit block 312 to move. The limit block 312 restricts the movement of the buckle 21, thereby fixing the buckle 21 and completing the installation of the main unit 2. When the main unit 2 needs to be inspected and maintained, the operator first sends a signal to the rotary driver 321 through the controller. The rotary driver 321 drives the screw 322 to rotate, first separating the limit block 312 from the buckle 21. Then, the main unit 2 is lifted, so that the buckle 21 separates from the card holder 11, and the main unit 2 is removed.

[0052] Reference Figure 2 , Figure 3 and Figure 7 The microcomputer-controlled measurement and control device also includes an auxiliary device 4, which includes a sensing component 41, a locking component 42, and a transmission component 43. The sensing component 41 is mounted on the mounting frame 313 and is used to detect the opening and closing status of the locking component 42. The locking component 42 is mounted on the frame 1 and is used to lock the mounting frame 313. The transmission component 43 is connected to the locking component 42 and is used to control the opening and closing of the locking component 42.

[0053] This invention achieves the function of automatically activating the limiting component 31 after the main unit 2 is installed through the sensing component 41, locking component 42, and transmission component 43, thereby further improving the portability of the main unit 2. The sensing component 41 is electrically connected to the controller. When installing the main unit 2, after the operator assembles the main unit 2 with the frame 1, the locking component 42 is first locked by the transmission component 43. After the sensing component 41 senses that the locking component 42 is closed, it sends a feedback signal to the controller. The controller sends a signal to the rotary driver 321. The rotary driver 321 drives the screw 322 to rotate through the bevel gear 325. The screw 322 drives the mounting bracket 313, which is threadedly connected to it, to move. The mounting bracket 313 drives the limiting block 312 to move along the guide rail 311. The buckle 21 is fixed in place, restricting its movement. When disassembling the main unit 2, the operator sends a signal to the rotary driver 321 through the controller. After receiving the signal, the rotary driver 321 drives the screw 322 to rotate, which in turn drives the mounting bracket 313 and the limit block 312 to move, releasing the restriction on the buckle 21. At the same time, after the limit block 312 is reset, the locking component 42 automatically opens and locks the mounting bracket 313, thereby preventing the limit component 31 from being activated when the main unit 2 is not installed, thus avoiding obstruction to the installation of the main unit 2.

[0054] Reference Figure 3 and Figure 6 The locking assembly 42 includes a mounting box 421, an arc-shaped locking block 422, and a first elastic element 423. The mounting box 421 is mounted on the frame 1. The arc-shaped locking block 422 is slidably mounted on the mounting box 421, and the transmission assembly 43 is connected to the arc-shaped locking block 422 in a transmission manner. The two ends of the first elastic element 423 are respectively connected to the arc-shaped locking block 422 and the mounting box 421.

[0055] This invention achieves the function of restricting the movement of the mounting bracket 313 through the mounting box 421, the arc-shaped locking block 422, and the first elastic element 423. When installing the main unit 2, after aligning the main unit 2 with the frame 1, the operator first uses the transmission component 43 to overcome the elastic force of the first elastic element 423, controlling the arc-shaped locking block 422 to move closer to the mounting box 421, thus releasing the locking component 42. After the sensing component 41 detects that the locking component 42 is closed, it sends a feedback signal to the controller. The controller then sends a signal to the rotary driver 321. The rotary driver 321 drives the screw 322 to rotate via the bevel gear 325. The screw 322 drives the mounting bracket 313, which is threadedly connected to it, to move. The mounting bracket 313 then moves the limiting block 312 along the guide rail 311, engaging the latch 2. 1. Fixing and restricting its movement; while disassembling the main unit 2, the operator sends a signal to the rotary driver 321 through the controller. After receiving the signal, the rotary driver 321 drives the screw 322 to rotate, which in turn drives the mounting bracket 313 and the limiting block 312 to move, releasing the restriction on the buckle 21. At the same time, during the resetting process of the limiting block 312, the mounting bracket 313 contacts and presses the arc surface of the arc-shaped locking block 422. After the mounting bracket 313 passes the arc-shaped locking block 422, the arc-shaped locking block 422 resets under the elastic force of the first elastic element 423, locking the mounting bracket 313.

[0056] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 The sensing component 41 includes a guide rod 411, a sensing block 412, a first pressure sensor 413, and a second elastic element 414. The guide rod 411 is mounted on the mounting bracket 313. The sensing block 412 is slidably mounted on the mounting bracket 313 and is slidably engaged with the guide rod 411. The first pressure sensor 413 is mounted on the sensing block 412. The two ends of the second elastic element 414 are respectively connected to the first pressure sensor 413 and the mounting bracket 313.

[0057] This invention achieves the function of monitoring the state of the locking assembly 42 through the guide rod 411, the sensing block 412, the first pressure sensor 413, and the second elastic element 414. The first pressure sensor 413 is electrically connected to the controller; when disassembling the main unit 2, the operator sends a signal to the rotary driver 321 through the controller. After receiving the signal, the rotary driver 321 drives the screw 322 to rotate, which in turn drives the mounting bracket 313 and the limiting block 312 to move, releasing the restriction on the buckle 21. At the same time, during the resetting process of the limiting block 312, the mounting bracket 313 contacts and presses the arc surface of the arc-shaped locking block 422. After the mounting bracket 313 passes the arc-shaped locking block 422, the arc-shaped locking block 422 resets under the elastic force of the first elastic element 423, locking the mounting bracket 313. After a complete reset, the controller sends a signal to the rotary driver 321 again. Upon receiving the signal, the rotary driver 321 drives the screw 322 to rotate, which in turn drives the mounting bracket 313 to move closer to the card holder 11. Meanwhile, the sensing block 412 is blocked by the arc-shaped card block 422 and cannot move. The second elastic element 414 is compressed, and the pressure sensed by the first pressure sensor 413 increases. It sends a feedback signal to the controller. When the pressure value reaches the set value, the controller stops the rotary driver 321 and maintains this state until the operator installs the main unit 2. The transmission component 43 then controls the arc-shaped card block 422 to move, releasing the restriction on the mounting bracket 313.

[0058] Reference Figure 3 and Figure 9 A pressure block 111 is slidably mounted on the card holder 11, and the pressure block 111 is connected to the transmission assembly 43. A second pressure sensor 113 is mounted on the card holder 11. A third elastic element 112 is mounted on the pressure block 111, and the two ends of the third elastic element 112 are respectively connected to the second pressure sensor 113 and the pressure block 111.

[0059] The present invention realizes the function of controlling the movement of the arc-shaped locking block 422 by using the weight block 111, the third elastic element 112 and the second pressure sensor 113, thereby achieving the effect of automatically activating the limit component 31 to fix the locking block 21 when installing the host 2. When the operator installs the main unit 2, after aligning the main unit 2 with the frame 1, the third elastic element 112 contracts under the pressure of the main unit 2 and the buckle 21, and the pressure block 111 moves downward. The third pressure sensor senses the pressure change and sends a feedback signal to the controller. At the same time, the pressure block 111 overcomes the elastic force of the first elastic element 423 through the transmission component 43, controlling the arc-shaped locking block 422 to move towards the mounting box 421, releasing the locking component 42. After the sensing component 41 senses that the locking component 42 is closed, it sends a feedback signal to the controller. The controller sends a signal to the rotary driver 321. The rotary driver 321 drives the screw 322 to rotate through the bevel gear 325. The screw 322 drives the mounting bracket 313, which is threadedly connected to it, to move. The mounting bracket 313 drives the limit block 312 to move along the guide rail 311, fixing the buckle 21 and restricting its movement, thus completing the fixing of the main unit 2. When disassembling the main unit 2, the operator sends a signal to the rotary driver 321 via the controller. Upon receiving the signal, the rotary driver 321 drives the screw 322 to rotate, which in turn drives the mounting bracket 313 and the limiting block 312 to move, releasing the restriction on the latch 21. Simultaneously, during the resetting process of the limiting block 312, the mounting bracket 313 contacts and presses against the arc-shaped locking block 422. After the mounting bracket 313 passes the arc-shaped locking block 422, the arc-shaped locking block 422 resets under the elastic force of the first elastic element 423, locking the mounting bracket 313. After the mounting bracket 313 has fully reset, the controller... The signal is sent to the rotary driver 321 again. After receiving the signal, the rotary driver 321 drives the screw 322 to rotate. The screw 322 drives the mounting bracket 313 to move closer to the card holder 11. The sensing block 412 is blocked by the arc-shaped card block 422 and cannot move. The second elastic element 414 is compressed, and the pressure sensed by the first pressure sensor 413 increases. Its feedback signal is sent to the controller. When the pressure value reaches the set value, the controller stops the rotary driver 321 and maintains this state until the operator installs the main unit 2. The transmission component 43 controls the arc-shaped card block 422 to move and release the restriction on the mounting bracket 313.

[0060] Reference Figures 7-10 The transmission assembly 43 includes a connecting frame 431, a connecting buckle 432, and a mounting strip 433. The two ends of the connecting frame 431 are connected to the pressure block 111 and the mounting strip 433, respectively. The connecting buckle 432 is connected to the arc-shaped locking block 422, and the connecting buckle 432 is provided with a slanted groove 4321. The mounting strip 433 is slidably mounted on the frame 1, and a push block 4331 is provided on the mounting strip 433. The push block 4331 abuts against the slanted groove 4321 of the connecting buckle 432.

[0061] The present invention realizes the functions of connecting the pressure block 111 and the arc-shaped locking block 422 through the connecting frame 431, the connecting buckle 432 and the mounting strip 433, thereby achieving the effect of automatically controlling the opening and closing of the locking component 42. When the operator installs the main unit 2, after aligning the main unit 2 with the frame 1, the third elastic element 112 contracts under the pressure of the main unit 2 and the buckle 21, causing the pressure block 111 to move downwards. The third pressure sensor senses the pressure change and sends a feedback signal to the controller. Simultaneously, the pressure block 111 moves the mounting strip 433 via the connecting bracket 431. The mounting strip 433 moves the push block 4331, which presses against the inclined groove 4321 of the connecting buckle 432, thereby driving the connecting buckle 432 to move. The connecting buckle 432 overcomes the elastic force of the first elastic element 423, controlling the arc-shaped locking block 422 to move towards the mounting box 421, releasing the locking assembly 42. After the sensing assembly 41 senses that the locking assembly 42 is closed, it sends a feedback signal to the controller. The controller then sends a signal to the rotary driver 321. The rotary driver 321 drives the screw 322 to rotate via the bevel gear 325. The screw 322 drives the mounting bracket 313, which is threadedly connected to it, to move. Mounting bracket 313 drives limiting block 312 to move along guide rail 311, fixing buckle 21 and restricting its movement, thus fixing the main unit 2. When disassembling the main unit 2, the operator sends a signal to rotary driver 321 through the controller. After receiving the signal, rotary driver 321 drives screw 322 to rotate, which in turn drives mounting bracket 313 and limiting block 312 to move, releasing the restriction on buckle 21. At the same time, during the resetting process of limiting block 312, mounting bracket 313 contacts and presses the arc surface of arc-shaped buckle 422. After mounting bracket 313 passes arc-shaped buckle 422, arc-shaped buckle 422 resets under the elastic force of first elastic element 423, locking mounting bracket 313. Then, the main unit 2 drives buckle 21 to move. After pressure block 111 loses pressure, it resets under the action of third elastic element 112, and then presses push block 4331 through inclined groove 4321, so that mounting strip 433 resets.

[0062] Reference Figure 8 A roller 424 is rotatably mounted on the arc-shaped locking block 422.

[0063] This invention reduces wear between the arc-shaped locking block 422 and the mounting bracket 313 by using a roller 424. This achieves the effect of replacing the sliding friction between the arc-shaped locking block 422 and the sensing block 412 with rolling friction between the roller 424 and the sensing block 412. During the resetting process of the mounting bracket 313, it moves the sensing block 412. After the sensing block 412 contacts the arc surface of the arc-shaped locking block 422, it presses against the arc-shaped locking block 422. During this process, under the elastic force of the first elastic element 423, the arc-shaped locking block 422 experiences intense friction with the sensing block 412. The roller 424 is provided to replace the sliding friction between the arc-shaped locking block 422 and the sensing block 412 with rolling friction, thereby improving the service life of the parts and enhancing the movement stability of the mounting bracket 313 and the sensing block 412. When disassembling the main unit 2, the operator sends a signal to the rotary driver 321 through the controller. After receiving the signal, the rotary driver 321 drives the screw 322 to rotate, which in turn drives the mounting bracket 313 and the limiting block 312 to move, thereby releasing the restriction on the buckle 21. At the same time, during the resetting process of the limiting block 312, the mounting bracket 313 contacts and presses the arc surface of the arc-shaped locking block 422. After the mounting bracket 313 passes the arc-shaped locking block 422, the arc-shaped locking block 422 resets under the elastic force of the first elastic element 423, locking the mounting bracket 313.

[0064] Reference Figure 2 The guide housing 12 is mounted on the frame 1.

[0065] The outer surface of the guide housing 12 is arc-shaped, and a notch is provided on the mounting bracket 313 at the bottom of the frame 1.

[0066] This invention utilizes the guide shell 12 to guide the movement of the main unit 2 during installation, thereby improving the portability of the main unit 2 during installation. By providing a notch on the mounting bracket 313 to avoid obstructing the guide shell 12, the installation of the guide shell 12 does not impede the movement of the mounting bracket 313 at the bottom of the frame 1. At the same time, the guide shell 12 encloses the screw 322 at the bottom of the frame 1, thereby preventing the main unit 2 from contacting the screw 322, reducing wear on the screw 322, and improving the stability of the movement of the mounting bracket 313.

[0067] Reference Figure 4 and Figure 5 The linear drive assembly 32 also includes a reinforcing frame 323 and a connecting block 324; the reinforcing frame 323 is threadedly connected to the screw 322; the connecting block 324 is connected to the reinforcing frame 323 and the mounting bracket 313.

[0068] This invention improves the structural stability of the limiting block 312 and the mounting frame 313 through the reinforcing frame 323 and the connecting frame 431. Since the limiting block 312 is pushed by the mounting frame 313, and the gap between the limiting block 312 above the frame 1 and the screw 322 is relatively large, the reinforcing frame 323 and the connecting block 324 are provided. The connection between the reinforcing block and the connecting block 324 further stabilizes the movement of the limiting block 312 and improves its structural stability. When disassembling the main unit 2, the operator sends a signal to the rotary driver 321 via the controller. Upon receiving the signal, the rotary driver 321 drives the screw 322 to rotate, which in turn drives the mounting bracket 313 and the limiting block 312 to move, releasing the restriction on the latch 21. Simultaneously, during the resetting process of the limiting block 312, the mounting bracket 313 contacts and presses against the arc-shaped locking block 422. After the mounting bracket 313 passes the arc-shaped locking block 422, the arc-shaped locking block 422 resets under the elastic force of the first elastic element 423, locking the mounting bracket 313. After the mounting bracket 313 has fully reset, the controller... The signal is sent to the rotary driver 321 again. After receiving the signal, the rotary driver 321 drives the screw 322 to rotate. The screw 322 drives the mounting bracket 313 to move closer to the card holder 11. The sensing block 412 is blocked by the arc-shaped card block 422 and cannot move. The second elastic element 414 is compressed, and the pressure sensed by the first pressure sensor 413 increases. Its feedback signal is sent to the controller. When the pressure value reaches the set value, the controller stops the rotary driver 321 and maintains this state until the operator installs the main unit 2. The transmission component 43 controls the arc-shaped card block 422 to move and release the restriction on the mounting bracket 313.

[0069] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
