Description

Technical Field

[0001] This utility model relates to the field of five-proof interlocking technology, and in particular to a highly efficient and stable microcomputer-based five-proof device. Background Technology

[0002] The microcomputer-based five-prevention device, also known as the microcomputer-based anti-misoperation interlocking device, is a computer-based device used in high-voltage switchgear to prevent electrical misoperation. After years of development, this device has matured and is widely used in power systems. Currently, the microcomputer-based anti-misoperation interlocking device primarily uses safety interlocking devices. Based on their working principles, these interlocking devices are mainly divided into two categories: mechanical interlocking and electrical interlocking. Mechanical interlocking often uses a gear-rack transmission mechanism. The gear, as the driving element, is usually driven by manual operation, while the rack, as the driven element, meshes with the gear and moves along a linear guide rail, achieving linear displacement of the interlocking mechanism. The gear-rack meshing is a rigid connection, and reverse transmission is physically blocked, effectively preventing forced unlocking after interlocking.

[0003] However, gear-rack transmission mechanisms usually require two-hand operation, which is cumbersome and inefficient. Furthermore, the gears and racks in gear-rack transmission mechanisms are prone to wear, making it impossible to guarantee the stable operation of the locking device. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide a highly efficient and stable microcomputer-based five-proof device.

[0005] This utility model provides a highly efficient and stable microcomputer-based five-proof device, comprising:

[0012] According to the technical solution provided in the embodiments of this application, the first limiting block has a first limiting groove on its end face near the connecting end face, a limiting post is provided in the first limiting groove, and a first limiting rod is connected to one end of the limiting post away from the first limiting groove.

Compared with the traditional gear-rack transmission mechanism, this reduces operation delay, improves response speed, and makes the unlocking process more efficient. The abutting design of the third and fourth limiting plates ensures that the tongue plate is firmly fixed in the locked state, effectively preventing accidental unlocking due to vibration or external force, and improving the safety of the device. During unlocking, the user can push the push rod with one hand. The linear up-and-down movement design of the push rod is simple and direct, with a fast response speed, which can reduce operation steps and time, and greatly improve efficiency.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0040] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Please refer to Figures 1 to 8 The present invention provides a highly efficient and stable microcomputer-based five-proof device, comprising: a housing 1, a transmission mechanism 4 provided on the inner wall of the bottom of the housing 1, the transmission mechanism 4 including a tongue plate 44, the first end of the tongue plate 44, i.e. the right end of the tongue plate 44, being inserted and connected to the inner wall of the bottom of the housing 1, a fourth limiting plate 55 provided in the middle of the tongue plate 44, a second elastic element 43 provided at the end of the fourth limiting plate 55 away from the tongue plate 44; and a fixing mechanism 5 provided on one side of the middle of the tongue plate 44, the fixing mechanism 5 including a third limiting plate 52 abutting against the end face of the fourth limiting plate 55 away from the tongue plate 44.

[0042] The unlocking mechanism 2 includes a push rod 21 that passes through the top of the box 1. The push rod 21 can move in the up and down direction. When the push rod 21 moves downward, it pushes the third limiting plate 52 and the fourth limiting plate 55 to separate. The second elastic member 43 drives the tongue plate 44 to move away from the head end of the tongue plate 44, that is, the second elastic member 43 drives the tongue plate 44 to move to the left.

[0043] The locking mechanism 3 includes a first rotatable transmission rod 32 that passes through the top of the housing 1, and a second scraper 35 is provided at the bottom of the first transmission rod 32; a second limiting plate 37 extending in the upward direction is also provided on the tongue plate 44; when the first transmission rod 32 rotates counterclockwise, it drives the second scraper 35 to push the second limiting plate 37, and drives the tongue plate 44 to move closer to the head end of the tongue plate 44, that is, the second elastic element 43 drives the tongue plate 44 to move to the right.

[0044] In this invention, the housing 1 provides rigid support to ensure accurate positioning of each component, reducing the impact of external vibration or impact on the internal mechanism and improving overall stability. When unlocking, the second elastic element 43 in the transmission mechanism 4 quickly releases its elastic potential energy, directly driving the tongue plate 44 to move to the left. Compared to traditional gear-rack transmission mechanisms, this reduces operational delay, improves response speed, and makes the unlocking process more efficient. The abutment design of the third and fourth limiting plates 52 and 55 ensures that the tongue plate 44 is firmly fixed in the locked state, effectively preventing accidental unlocking due to vibration or external force and improving device safety. During unlocking, the user can push the push rod 21 with one hand. The linear up-and-down movement of the push rod 21 is simple and direct, with a fast response speed, reducing operation steps and time, and greatly improving efficiency. During locking, the user can rotate the first transmission rod 32 with one hand. The counterclockwise rotation of the first transmission rod 32 is converted into linear movement of the tongue plate 44 through the second scraper 35, making the pushing process smooth and fast, effectively reducing operation time.

[0045] In addition, this invention does not use electronic components and does not rely on an external power source. In the event of a circuit failure or other emergency, this invention can still continue to work, thus improving the stability of the locking device.

[0046] In some embodiments, the transmission mechanism 4 includes a transmission housing 41 disposed on the inner wall of the bottom of the housing 1. A second groove is provided on the end face of the transmission housing 41 near the tongue plate 44. A second transmission rod 42 is slidably connected in the second groove. The end of the second transmission rod 42 away from the transmission housing 41 is connected to the tail end of the tongue plate 44, that is, the left end of the tongue plate 44. A second limiting plate 37 is located at the end of the second transmission rod 42 near the tongue plate 44. A fourth limiting plate 55 and a second elastic member 43 are both fitted outside the second transmission rod 42.

[0047] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the position of the second groove in the transmission housing 41 can be referenced. Figure 8 It provides precise linear guidance for the second transmission rod 42, restricting it to move only in the direction parallel to the tongue plate 44, which can effectively prevent the second transmission rod 42 from shifting laterally or twisting; the second transmission rod 42, as a rigid connecting rod, cooperates with the fourth limiting plate 55 and the second elastic member 43, which can directly release the elastic force of the second elastic member 43, reduce the response time of the device, and improve the operating efficiency.

[0048] In some embodiments, the fixing mechanism 5 includes a first fixing rod 51 disposed on the inner wall of the bottom of the housing 1, and a first support column 54 disposed on the inner wall of the bottom of the housing 1 between the first fixing rod 51 and the second transmission rod 42. The top end of the first support column 54 is rotatably connected to the third limiting plate 52. The third limiting plate 52 has a first through hole at one end away from the second transmission rod 42 for the first fixing rod 51 to pass through. The diameter of the first through hole is larger than the diameter of the first fixing rod 51. A third elastic member 53 is fitted on the outside of the first fixing rod 51. One end of the third elastic member 53 is connected to the inner wall of the bottom of the housing 1, and the other end is connected to the bottom end face of the third limiting plate 52.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the first support column 54 and the third limiting plate 52 form a lever structure. The first support column 54 is the fulcrum for the rotation of the third limiting plate 52, which can ensure that the top of the third limiting plate 52 and the contact surface of the fourth limiting plate 55 are perpendicularly attached, thus improving the stability of the device. The first fixing rod 51, as a rigid guide rail, passes through the first through hole, which can effectively prevent the third limiting plate 52 from shifting during displacement. The diameter of the first through hole is larger than the diameter of the first fixing rod 51, which facilitates the third limiting plate 52 to move up and down along the first fixing rod 51. The third elastic element 53 can provide a force to make the third limiting plate 52 swing downward with the first support column 54 as the fulcrum, so that the third limiting plate 52 and the fourth limiting plate 55 are firmly abutted, which is beneficial to improving the stability of the locking device.

[0050] In addition, the shape of the third limiting plate 52 is not limited, and it can form a lever structure with the first support column 54 and can lock the fourth limiting plate 55. The shape of the third limiting plate 52 used in this utility model is more in line with the transmission mechanism 4, which is conducive to improving the stability of the locking device.

[0051] In some embodiments, a third fixing plate 13 is fixedly connected to the middle of the housing 1; the unlocking mechanism 2 includes a first protective block 22 disposed on the top surface of the third fixing plate 13, the end face of the first protective block 22 near the first transmission rod 32 is a connecting end face, and a first groove is provided on the connecting end face; the push rod 21 passes through the first protective block 22 and the third fixing plate 13, and a first limiting block 23 located inside the first groove is fitted on the outside of the push rod 21, and a first elastic element 24 is connected between the first limiting block 23 and the inner wall of the bottom of the first groove.

[0052] like Figures 1-6 As shown, the third fixing plate 13 provides a central support point for the push rod 21 to prevent the push rod 21 from bending and deforming under force; the first groove of the first protective block 22 can restrict the first limiting block 23, allowing it to move only along the axial direction of the push rod 21; the first limiting block 23 provides a mounting base for subsequent components; the first elastic element 24 can absorb the impact energy when the push rod 21 is pressed down quickly, preventing the push rod 21 from wearing and being damaged, which is beneficial to improving the stability of the device, and can ensure that the push rod 21 automatically rebounds to the initial position after operation, while limiting the maximum stroke to avoid excessive displacement causing component collision.

[0053] In some embodiments, the end face of the first limiting block 23 near the connecting end face is provided with a first limiting groove 231, and a limiting post 252 is provided in the first limiting groove 231. The end of the limiting post 252 away from the first limiting groove 231 is connected to a first limiting rod 251. The first limiting rod 251 is an L-shaped rod, and the other end of the first limiting rod 251 is rotatably connected to the connecting end face. The first limiting rod 251 and the limiting post 252 constitute a limiting part 25. The bottom end of the push rod 21 is provided with a contact block 26, which can abut against the top end of the third limiting plate 52.

[0054] The first limiting groove 231 includes, from top to bottom, a first V-shaped groove, two connecting grooves, and a second V-shaped groove. The two connecting grooves connect the two top ends of the first V-shaped groove and the second V-shaped groove respectively. When the push rod 21 moves downward, the limiting post 252 moves from the lowest point of the second V-shaped groove to the lowest point of the first V-shaped groove, thus limiting the movement of the push rod 21 in the vertical direction.

[0055] like Figures 2-6 As shown, the first limiting groove 231, together with the limiting post 252 and the first limiting rod 251 of the limiting part 25, further restricts the vertical displacement of the push rod 21, preventing excessive displacement of the push rod 21 from causing component collision. The first limiting groove 231 adopts a composite path design of double V-shaped groove + connecting groove. Before the push rod 21 is pressed down, the limiting post 252 is located at the lowest point of the second V-shaped groove and is in a locked state, which can effectively prevent the push rod 21 from accidentally moving down. After the push rod 21 is pressed down, the limiting post 252 is forced to move up along the connecting groove and slide into the lowest point of the first V-shaped groove, which can effectively release the vertical movement freedom of the push rod 21 and provide some basis for the subsequent setting of the locking mechanism 3. The contact block 26 can be made of hardened alloy material to ensure rigid contact with the third limiting plate 52 without elastic deformation, realize zero-delay response of the limiting plate separation action, and improve the operating efficiency of the device.

[0056] In some embodiments, the locking mechanism 3 further includes a first limiting plate 36 disposed at the end of the limiting post 252 away from the first limiting groove 231; a first scraper 34 is fixedly connected to the side surface of the first transmission rod 32; when the first transmission rod 32 rotates counterclockwise, it drives the first scraper 34 to push the first limiting plate 36, and drives the limiting post 252 to move to the highest point of the first V-shaped groove of the first limiting groove 231, so that the push rod 21 moves downward and pushes the third limiting plate 52 and the fourth limiting plate 55 to separate; at the same time, it drives the second scraper 35 to push the second limiting plate 37, and drives the tongue plate 44 to move towards the head end of the tongue plate 44.

[0057] Furthermore, a second limiting groove 371 is provided on one end face of the second limiting plate 37 near the first transmission rod 32. The second limiting groove 371 is used to limit the movement of the second scraper 35.

[0058] like Figures 1 to 7 As shown, when the first scraper 34 pushes the first limiting plate 36 and the limiting post 252 reaches the highest point of the first V-groove, the third limiting plate 52 separates from the fourth limiting plate 55, and the second scraper 35 just begins to contact the second limiting plate 37, driving the tongue plate 44 to move to the right to complete the locking. After that, the push rod 21 will return to its original position under the elastic force of the first elastic element 24. A single rotation of the first transmission rod 32 can make the unlocking mechanism 2 return to the locked state and complete the locking process at the same time. This can greatly improve the operating efficiency of the device and reduce the operating time.

[0059] In some embodiments, a second fixing plate 12 is fixedly connected to the bottom of the housing 1; a first transmission rod 32 is rotatably connected to the top surface of the second fixing plate 12, a rotating handle 31 is connected to the top of the first transmission rod 32, a torsion spring 33 is fixedly connected to the outside of the first transmission rod 32, and the other end of the torsion spring 33 is fixedly connected to the inner wall of the top of the housing 1.

[0060] like Figures 1 to 7 As shown, the second fixed plate 12 provides an installation base for the locking mechanism 3, and the rotating handle 31 is easy for personnel to hold and perform rotation operations; the torsion spring 33 makes the first transmission rod 32 automatically return to its original position after rotation, further reducing the operation time of personnel and improving operation efficiency.

[0061] In some embodiments, the bottom inner wall of the box 1 is further provided with a drying section 6, which is used to absorb water vapor inside the box 1.

[0062] Optionally, the drying section 6 includes a drying shell 61 located on the inner wall of the bottom of the box body 1. Small holes are evenly distributed on the drying shell 61, and a first cavity is provided inside the drying shell 61 for storing desiccant. The box body 1 has an opening on the outer side corresponding to the drying shell 61. The drying section 6 also includes a detachable plate 62 that fits the shape of the opening. The detachable plate 62 is also provided with a handle 63, which is convenient for personnel to hold.

[0063] like Figures 1-3 As shown, the drying section 6 is located at the bottom of the chamber 1, which can effectively remove water vapor inside the chamber 1; the removable plate 62 facilitates personnel to replace the desiccant, which helps to keep the inside of the chamber 1 in a dry state at all times and prevents the equipment inside the chamber 1 from rusting.

[0064] In some embodiments, a sealing shell 7 is provided on the top of the housing 1. The sealing shell 7 is used to prevent dust from entering the housing 1 through the gap between the unlocking mechanism 2, the locking mechanism 3 and the housing 1.

[0065] Optionally, the sealing shell 7 is rotatably connected to the top of the housing 1.

[0066] like Figure 1 As shown, the sealing shell 7 can effectively prevent dust from entering the box 1 through the gap between the unlocking mechanism 2, the locking mechanism 3 and the box 1, thereby damaging the device inside the box 1.

[0067] The process of using the device:

[0068] When unlocking is required, push rod 21 is pressed down, push rod 21 moves down, limit post 252 moves from the lowest point of the second V groove to the lowest point of the first V groove, contact block 26 pushes the third limit plate 52 and the fourth limit plate 55 to separate, second elastic element 43 drives tongue plate 44 to move to the left, and unlocking is completed.

[0069] When locking is required, the rotating handle 31 is rotated counterclockwise. The rotating handle 31 drives the first transmission rod 32 to rotate, and the first transmission rod 32 drives the first scraper 34 and the second scraper 35 to rotate. When the first scraper 34 pushes the first limiting plate 36 and the limiting post 252 reaches the highest point of the first V-groove, the contact block 26 pushes the third limiting plate 52 and the fourth limiting plate 55 to separate. The second scraper 35 just begins to contact the second limiting plate 37, driving the tongue plate 44 to move to the right to complete the locking. Afterwards, the push rod 21 will return to its original position under the elastic force of the first elastic element 24.
