Technical Field

[0001] This utility model relates to the field of electrical device technology, specifically to a pressure plate status monitoring device capable of achieving secondary anti-misoperation. Background Technology

[0002] The trip plate, also called the protection connector or trip plate, is the bridge and link between the protection device and the external wiring. It is related to whether the protection function and the action output can play a normal role. According to the different positions of the trip plate connected to the secondary circuit of the protection device, it can be divided into two categories: protection function trip plates and output trip plates. The protection function trip plate realizes certain functions of the protection device. In order to meet the needs of the market, there is a need for a trip plate status monitoring device that can realize secondary error prevention.

The surface of the pressure plate detector is provided with a pressure plate detection accessory, which engages with the surface of the pressure plate detector.

[0007] Preferably, the internal components of the convenient installation mechanism include a telescopic spring, an arc-shaped clamp, a positioning pin, a support plate, and an elastic clamp. The inner walls of the device frame are all equipped with positioning pins, which engage with the inner walls of the mounting plate. One end of the positioning pin extends to the outer side of the mounting plate. The inner walls on both sides of the unit protection cabinet are equipped with support plates. The surface at the bottom of the mounting plate is equipped with elastic clamps, which engage with the surface of the support plate.

[0008] Preferably, the inner walls on both sides of the unit protection cabinet are provided with arc-shaped clips, which slide in cooperation with the inner walls of the unit protection cabinet, and the arc-shaped clips engage with the surface of the mounting plate. Each arc-shaped clip is equipped with a telescopic spring, and one end of the telescopic spring is fixed to the inner wall of the unit protection cabinet.

[0009] Preferably, the anti-disconnection mechanism consists of a fixed ring, a extension spring, a spring column, a rubber pad, and an arc-shaped clamp. The surfaces of the pressure plate controller and the intelligent pressure plate back-end management system are both equipped with fixed rings. One end of the line extends into the interior of the fixed ring and is connected to the pressure plate controller and the intelligent pressure plate back-end management system respectively. The interior of each fixed ring is provided with an arc-shaped clamp. The inner wall of the arc-shaped clamp is adhered with a rubber pad, and the inner wall of the rubber pad is in contact with the surface of the line.

[0010] Preferably, the inner wall of the fixing ring is equipped with equally spaced elastic columns. One end of each elastic column is fixed to the surface of the arc-shaped clamping plate. An extension spring is fitted onto the surface of each elastic column. One end of the extension spring is fixed to the inner wall of the fixing ring, and the other end of the extension spring is fixed to the surface of the arc-shaped clamping plate.

[0011] Preferably, the secondary anti-misoperation mechanism includes a fixing block, a block body, and a secondary anti-misoperation group.

[0012] Preferably, each of the pressure plate detectors has a block mounted on its surface, a female hook and loop fastener mounted on the surface of the block, and a male hook and loop fastener mounted on the surface of the fixing block, with the male hook and loop fastener and the female hook and loop fastener cooperating with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the pressure plate status monitoring device that can realize secondary error prevention not only allows the pressure plate detector to be installed on the surface of the mounting plate and the device frame plate respectively, making the monitoring effect of the monitoring device better, and allows the mounting plate to be installed on the surface of the device frame plate respectively, making the monitoring device more convenient for users to operate, but also prevents the line from becoming loose or disconnected between the pressure plate controller and the intelligent pressure plate background management system, making the monitoring device more practical;

[0014] 1. By incorporating a secondary anti-misoperation mechanism, the user places the pressure plate detectors on the surface of the mounting plate, causing the pressure plate detectors to move the block to one side of the fixed block. The block then moves the female hook and loop fastener to contact the surface of the female hook and loop fastener. Under the combined action of the female and female hook and loop fasteners, the fixed block and the female hook and loop fastener are secured. This allows the pressure plate detectors to be installed on the surfaces of both the mounting plate and the device frame, enabling the monitoring device to detect the pressure plate during use. This achieves the secondary anti-misoperation function of the monitoring device, resulting in better monitoring performance when the pressure plate detectors are installed on both the mounting plate and the device frame.

[0015] 2. With a convenient installation mechanism, the user tightens the mounting screws on the surface of the device frame plate and installs the device frame plate on the inner wall of the unit's protection cabinet. The user places the mounting plates on the surface of the device frame plate, and one end of the positioning pin moves to the outside of the mounting plate. Under the action of the positioning pin, the mounting plate is positioned and installed. At this time, the mounting plate drives the elastic clip to automatically lock onto the surface of the support plate. Under the combined action of the elastic clip and the support plate, the mounting plate is securely installed. Under the elastic force of the telescopic spring, the arc-shaped clip automatically locks onto the surface of the mounting plate, thus installing the mounting plates on the surface of the device frame plate. This realizes the function of convenient installation of the monitoring device, so that the mounting plates can be installed on the surface of the device frame plate when the monitoring device is in use, making it more convenient for the user to operate the monitoring device.

[0016] 3. By incorporating an anti-disconnection mechanism, the cable is bundled under the action of the fixing ring. The combined action of the extension spring and elastic column on the inner wall of the fixing ring drives the arc-shaped clamp and rubber pad to move. This causes the arc-shaped clamp to move the rubber pad until it contacts the surface of the cable. The combined action of the rubber pad and the arc-shaped clamp clamps the cable inside the fixing ring, preventing it from detaching from the pressure plate controller and the intelligent pressure plate back-end management system. This achieves the anti-disconnection function of the monitoring device, ensuring that the cable does not detach from the pressure plate controller and the intelligent pressure plate back-end management system during use, thus enhancing the practicality of the monitoring device.

[0026] Furthermore, such as Figure 2 and Figure 4As shown, the inner wall of the unit protection cabinet 101 and the surface of the mounting plate 104 are provided with a convenient installation mechanism 2. The convenient installation mechanism 2 includes a telescopic spring 21, an arc-shaped clamp 22, a positioning pin 23, a support plate 24, and an elastic clamp 25. The inner wall of the device frame plate 1 is equipped with positioning pins 23, which are engaged with the inner wall of the mounting plate 104. One end of the positioning pin 23 extends to the outer side of the mounting plate 104. The inner walls on both sides of the unit protection cabinet 101 are equipped with support plates 2. 4. Elastic clips 25 are installed on the bottom surface of the mounting plate 104. The elastic clips 25 are engaged with the surface of the support plate 24. Arc-shaped clips 22 are provided on the inner walls of both sides of the unit protection cabinet 101. The arc-shaped clips 22 are engaged with the inner walls of the unit protection cabinet 101. The arc-shaped clips 22 are engaged with the surface of the mounting plate 104. Telescopic springs 21 are installed on the surface of the arc-shaped clips 22. One end of the telescopic spring 21 is fixed to the inner wall of the unit protection cabinet 101.

[0027] During implementation, the user places the mounting plate 104 on the surface of the device frame plate 1. One end of the positioning pin 23 moves to the outside of the mounting plate 104, and the mounting plate 104 is positioned and installed under the action of the positioning pin 23. At this time, the mounting plate 104 drives the elastic clip 25 to automatically clip onto the surface of the support plate 24. Under the combined action of the elastic clip 25 and the support plate 24, the mounting plate 104 is stably installed. Under the elastic force of the telescopic spring 21, the arc-shaped clip 22 is automatically clipped onto the surface of the mounting plate 104, thereby installing the mounting plate 104 on the surface of the device frame plate 1 to realize the function of convenient installation of the monitoring device.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, the sticker 107, the intelligent pressure plate back-end management system 109, and the production line 111 are equipped with an anti-disconnection mechanism 3. The anti-disconnection mechanism 3 consists of a fixing ring 31, a tension spring 32, a spring column 33, a rubber pad 34, and an arc-shaped clamping plate 35. The pressure plate controller 103 and the intelligent pressure plate back-end management system 109 are both equipped with fixing rings 31. One end of the production line 111 extends into the interior of the fixing ring 31 and is connected to the pressure plate controller 103 and the intelligent pressure plate back-end management system 109, respectively. The inner wall of each fixing ring 31 is provided with an arc-shaped clamp 35. A rubber pad 34 is adhered to the inner wall of the arc-shaped clamp 35. The inner wall of the rubber pad 34 is in contact with the surface of the line body 111. The inner wall of each fixing ring 31 is equipped with equally spaced elastic columns 33.

One end of the tension spring 32 is fixed to the inner wall of the fixing ring 31, and the other end of the tension spring 32 is fixed to the surface of the arc-shaped clamp 35.

[0029] During implementation, the wire 111 is bundled under the action of the fixing ring 31. Under the combined action of the extension spring 32 and the elastic column 33 on the inner wall of the fixing ring 31, the arc-shaped clamping plate 35 and the rubber pad 34 are driven to move, so that the arc-shaped clamping plate 35 drives the rubber pad 34 to contact the surface of the wire 111. Under the combined action of the rubber pad 34 and the arc-shaped clamping plate 35, the wire 111 is clamped inside the fixing ring 31, preventing the wire 111 from coming loose from the surface of the pressure plate controller 103 and the intelligent pressure plate background management system 109, so as to realize the function of preventing disconnection of the monitoring device.

[0030] Furthermore, such as Figure 3 and Figure 6 As shown, the device frame plate 1 and the pressure plate detector 108 are both provided with secondary anti-misoperation mechanisms 4. The secondary anti-misoperation mechanism 4 includes a fixing block 41, a block 42 and a secondary anti-misoperation group 43. The secondary anti-misoperation group 43 is provided on the surface of the pressure plate detector 108. The secondary anti-misoperation group 43 is composed of a sub-hook and hook and loop fastener 431 and a female hook and loop fastener 432. The surface of the device frame plate 1 is provided with fixing blocks 41, the surface of the pressure plate detector 108 is provided with blocks 42, the surface of the block 42 is provided with female hook and loop fastener 432, and the surface of the fixing block 41 is provided with sub-hook and loop fastener 431. The sub-hook and loop fastener 431 and the female hook and loop fastener 432 cooperate with each other.

[0031] In practice, the user places the pressure plate detector 108 on the surface of the mounting plate 104, causing the pressure plate detector 108 to move the block 42 to one side of the fixing block 41. The block 42 then moves the female hook and loop fastener 432 to contact the surface of the female hook and loop fastener 431. Under the combined action of the female hook and loop fastener 432 and the female hook and loop fastener 431, the fixing block 41 and the female hook and loop fastener 432 are fixed together, thereby installing the pressure plate detector 108 on the surfaces of the mounting plate 104 and the device frame plate 1, so that the monitoring device can detect the pressure plate during use, thereby realizing the secondary anti-misoperation function of the monitoring device.

[0032] Working principle: In use, first place the device frame 1 in the designated position. The user places the pressure plate detector 108 on the surface of the mounting plate 104, causing the pressure plate detector 108 to move the block 42 to one side of the fixing block 41. The block 42 then moves the female hook and loop fastener 432 to contact the surface of the female hook and loop fastener 431. Under the combined action of the female hook and loop fastener 432 and the female hook and loop fastener 431, the fixing block 41 and the female hook and loop fastener 432 are fixed together, thus installing the pressure plate detector 108 on the surfaces of the mounting plate 104 and the device frame 1. This allows the monitoring device to detect the pressure plate during use, thereby achieving the secondary anti-misoperation function of the monitoring device. This ensures that the pressure plate detector 108 can be installed on the surfaces of the mounting plate 104 and the device frame 1 during use, resulting in better monitoring performance.

[0033] Subsequently, the user tightens the mounting screws 105 on the surface of the device frame plate 1, and installs the device frame plate 1 on the inner wall of the unit protection cabinet 101. The user places the mounting plates 104 on the surface of the device frame plate 1, and one end of the positioning pin 23 moves to the outside of the mounting plate 104. Under the action of the positioning pin 23, the mounting plate 104 is positioned and installed. At this time, the mounting plate 104 drives the elastic clip 25 to automatically clip onto the surface of the support plate 24. Under the combined action of the elastic clip 25 and the support plate 24, the mounting plate 104 is stably installed. Under the elastic force of the telescopic spring 21, the arc-shaped clip 22 is automatically clipped onto the surface of the mounting plate 104, thereby installing the mounting plates 104 on the surface of the device frame plate 1 to realize the function of convenient installation of the monitoring device. This makes it easier for the user to operate the monitoring device when it is in use.

[0034] Subsequently, a pressure plate detector 108 is installed above or below the pressure plate (determined according to actual conditions) to detect the pressure plate's engagement / disengagement status. Specifically, the pressure plate detector 108 works in conjunction with the pressure plate detection accessory 106, employing the Hall effect principle to detect the pressure plate's engagement / disengagement status and whether it is properly engaged or disengaged. When the pressure plate is engaged, the pressure plate detector 108 detects the signal from the pressure plate detection accessory 106, thus determining that the pressure plate is in the engaged state. The pressure plate controller 103 collects the status of all pressure plates within the unit's protection cabinet 101 and transmits it to the intelligent management host 110 via a protocol. The intelligent management host 110 is used for collecting the status of pressure plates across the entire station and transmitting protocols, supporting multiple protocol conversions, and interacting with the intelligent pressure plate backend management system 109 and third-party systems. The intelligent pressure plate backend management system 109 can realize various pressure plate operations such as pressure plate status display, abnormal alarms, and operation records. The pressure plate controller 103 monitors the dynamic changes of the pressure plates in real time, collecting and monitoring the pressure plate's position and communication status information, and transmitting it to the intelligent pressure plate backend management system 109. When the operation ticket is a combined operation ticket for primary equipment and secondary pressure plate, or when the pressure plate controller 103 is offline, the pressure plate controller 103 can also support operation by the computer key, receiving operation instructions issued by the computer key and sending the operation information back to the computer key. If the pressure plate malfunctions or fails to retract properly, the pressure plate controller 103 will issue an audible and visual alarm and send the pressure plate status to the computer key. When the computer key receives an operation instruction from the pressure plate controller 103, the status light of the pressure plate sensor will start flashing, indicating that it is currently in operation. The user can directly operate the pressure plate with the flashing status light, and the intelligent pressure plate background management system 109 will promptly issue an audible and visual alarm, requiring the error status to be resolved as soon as possible. Anomaly alarm for pressure plate status: When a pressure plate is accidentally moved due to external factors while no operation is being performed, the abnormal displacement information of the pressure plate is transmitted through the pressure plate controller 103 to the intelligent pressure plate background management system 109 and recorded in the database. Simultaneously, different flashing lights indicate the abnormal movement, allowing operators to easily detect abnormal pressure plate movements upon entering the station, significantly reducing the time required for pressure plate verification and improving efficiency. Operation result verification: Before each pressure plate operation, the intelligent pressure plate management system software automatically records the status of all pressure plates in the station. During operation, the pressure plate status is updated in real time. If the pressure plate status does not reach the target state of the operation task, the task cannot be completed, and the system will issue a prompt. The historical process of pressure plate operations, pressure plate status, etc., is recorded in detail in the pressure plate database. Users can view the historical operation records of pressure plates in the station at any time, and can browse them by year, quarter, month, day, etc., generating and printing the necessary reports for operators. Any malfunctions that occur during system operation will be promptly displayed in real time through the intelligent pressure plate background management system 109, the pressure plate controller 103, and the intelligent pressure plate, notifying maintenance personnel to troubleshoot in a timely manner.The intelligent pressure plate system management software, operating independently or embedded, can run independently on a computer host as a pressure plate control system, or it can be easily integrated into an anti-misoperation system or integrated automation system, forming an anti-misoperation system for primary and secondary equipment operation within the substation together with the operating system of the primary anti-misoperation equipment. Users can choose the operating mode according to their different needs.

[0035] Subsequently, when the cable 111 is connected to the pressure plate controller 103 and the intelligent pressure plate back-end management system 109 respectively, the cable 111 is bundled under the action of the fixing ring 31. Under the combined action of the extension spring 32 and the elastic column 33 on the inner wall of the fixing ring 31, the arc-shaped clamp 35 and the rubber pad 34 are driven to move, so that the arc-shaped clamp 35 drives the rubber pad 34 to contact the surface of the cable 111. Under the combined action of the rubber pad 34 and the arc-shaped clamp 35, the cable 111 is clamped inside the fixing ring 31, preventing the cable 111 from loosening from the surface of the pressure plate controller 103 and the intelligent pressure plate back-end management system 109, so as to realize the anti-disconnection function of the monitoring device. This prevents the cable 111 from loosening or breaking from the pressure plate controller 103 and the intelligent pressure plate back-end management system 109 during the use of the monitoring device, making the monitoring device more practical and finally completing the use of the monitoring device.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
