Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, specifically to a pressure plate and a protective cabinet. Background Technology

[0002] A pressure plate, also known as a protective pressure plate, electrical pressure plate, or connecting plate, is a manually operated electrical connection component typically installed in the secondary circuits of protection devices, monitoring and control devices, and other equipment. It enables or deactivates corresponding protection or automation functions by connecting or disconnecting the circuit. For example, to activate a protection function, closing the corresponding pressure plate (switching the corresponding pressure plate to the closed position) connects the protection device's circuit, and the protection function is in normal working condition. Conversely, to deactivate the function, opening the pressure plate (switching the corresponding pressure plate to the open position) disconnects the circuit, and the protection function ceases to function. Traditionally, pressure plates are activated or deactivated manually by tightening or loosening screws, or by pulling out or inserting handles, depending on the task at hand.

[0003] In practical use, this method leads to the following problems:

[0004] 1. Because the pressure plates are located on the protection and control panel, there are many of them and they are concentrated in one place. They are easy to miss or make operational errors. Misoperation may cause the protection device to malfunction or fail to operate, resulting in a safety accident.

[0005] 2. It mainly relies on manual operation, which is complex, labor-intensive, and has low inspection efficiency. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a pressure plate and a protective screen cabinet.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A pressure plate includes a pressure plate body, a main control module, and a motor drive module, a status detection module, a remote communication module, and a wireless carrier power supply communication module connected to the main control module. The pressure plate body is equipped with a motor, and the motor drive module is connected to the motor. The motor drives a conductive swing arm connected to the pressure plate body to swing and switch between a closed position and an open position. The status detection module is used to detect the position of the conductive swing arm and output it to the main control module. The remote communication module is used to communicate with a remote control terminal to realize the interaction between the main control module and the remote control terminal. The wireless carrier power supply communication module is used to wirelessly interact with an external handheld device.

[0009] Furthermore, the wireless carrier power supply communication module also supplies power to the main control module, motor drive module, status detection module and / or remote communication module.

[0010] Furthermore, the remote communication module is an RS485 communication module.

[0011] Furthermore, the state detection module is a Hall sensor or a limit switch. When the conductive swing arm switches to the closed position, the Hall sensor or limit switch is triggered and outputs a signal to the main control module.

[0012] Furthermore, it also includes an indicator module, which is connected to the main control module for indicating the status of the pressure plate body.

[0013] Furthermore, the pressure plate body specifically includes: a first conductive terminal, a second conductive terminal, the conductive swing arm, a stationary contact, the motor, and an insulating transmission component. The first conductive terminal and the second conductive terminal are spaced apart. One end of the conductive swing arm is rotatably disposed and electrically connected to the first conductive terminal. The stationary contact is electrically connected to the second conductive terminal. The motor drives the conductive swing arm through the insulating transmission component to drive the conductive swing arm to swing and switch between a closed position in electrical contact with the stationary contact and an open position separated from the stationary contact.

[0014] Furthermore, the insulated transmission component is an insulated gear transmission assembly; the gear transmission assembly includes a reduction gear set, a bushing, and a driven gear; the first conductive terminal has a fixed post; the bushing is rotatably sleeved on the fixed post; the conductive swing arm is fixed on the bushing to form a rotatable configuration; the conductive swing arm contacts the outer surface of the fixed post and is electrically connected to the first conductive terminal; the driven gear is fixed on the bushing; the rotating shaft of the motor is connected to the reduction gear set; the reduction gear set meshes with the driven gear.

[0015] Furthermore, the stationary contact is a spring with a "C" shaped cross-section, and when the conductive swing arm switches to the closed position, it is clamped and fixed by the stationary contact.

[0016] Furthermore, the pressure plate body also includes a housing, and the motor, main control module, motor drive module, status detection module, remote communication module and wireless carrier power supply communication module are all fixed on the housing.

[0017] A protective cabinet has a protective monitoring and control panel, on which a pressure plate is installed, and the pressure plate is the pressure plate described above.

[0018] The technical solution provided by this utility model has the following beneficial effects:

[0019] 1. The pressure plate of this application is driven by the motor drive module controlled by the main control module to realize the insertion and withdrawal of the pressure plate body, which can effectively solve the problem that the traditional pressure plate mainly relies on manual operation, which is complicated and has a large workload.

[0020] 2. The status detection module can monitor the engagement or disengagement status of the pressure plate body. Meanwhile, the remote communication module is used for remote interaction with the remote control terminal, enabling multi-point bus control. That is, the engagement or disengagement of multiple pressure plates on the protection and control panel can be centrally controlled through the remote control terminal. The wireless carrier power supply communication module enables wireless interaction with external handheld devices, enabling single-point control on site. That is, the operator can wirelessly interact with the pressure plate on site through a handheld device to achieve single-point control of a certain pressure plate.

[0021] In summary, this effectively solves the problems of large quantities being concentrated and prone to omissions and misoperations; the operation of this pressure plate is simpler and safer, improving work efficiency, and the collection and transmission of pressure plate engagement and disengagement status data can greatly improve inspection efficiency.

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element 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 this utility model.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 7 As shown, this embodiment provides a pressure plate, including a pressure plate body 1, a main control module 101, and a motor drive module 102, a status detection module 103, a remote communication module 104, and a wireless carrier power supply communication module 105 connected to the main control module 101. The pressure plate body 1 is equipped with a motor 30, and the motor drive module 102 is connected to the motor 30. The motor 30 drives a conductive swing arm 21 connected to the pressure plate body 1 to swing and switch between a closed position and an open position. The status detection module 103 is used to detect the position of the conductive swing arm 21 and output it to the main control module 101 to collect the deployment and retraction status of the pressure plate body 1. For example, if the status detection module 103 detects that the conductive swing arm 21 is in the closed position (e.g....), the pressure plate body 1 is deployed. Figure 5 (As shown), this indicates that the pressure plate body 1 is in the engaged state. When the state detection module detects that the conductive swing arm 21 is not in the closed position (such as being in the closed position), it means that the pressure plate body 1 is in the engaged state. Figure 6 If the disconnected position is shown, it indicates that the pressure plate body 1 is in the disengaged state.

[0033] The remote communication module 104 is used to establish a communication connection with a remote control terminal (such as a computer) to enable interaction between the main control module 101 and the remote control terminal; the wireless carrier power supply communication module 105 is used to wirelessly interact with an external handheld device to obtain data for transmission to the main control module 101, that is, the main control module 101 interacts with the external handheld device through the wireless carrier power supply communication module 105.

[0034] This can be understood as follows: the remote communication module 104 communicates with a remote control terminal (such as a computer) via wired or wireless means, while the wireless carrier power supply communication module 105 is used for contact communication with handheld devices on site.

[0035] This embodiment also provides a protection cabinet with a protection monitoring and control panel. The protection monitoring and control panel is equipped with a pressure plate. Specifically, a protection monitoring and control panel is equipped with multiple pressure plates for controlling the activation and deactivation of different functional devices. Specifically, the pressure plate is the pressure plate described above.

[0036] The pressure plate of this application is controlled by the main control module 101, which controls the motor drive module 102 to drive the motor 30 to realize the insertion and withdrawal of the pressure plate body 1. This can effectively solve the problem that traditional pressure plates mainly rely on manual operation, which is complicated and has a large workload.

[0037] The status detection module 103 is configured to monitor the engagement or disengagement status of the pressure plate body 1. Meanwhile, the remote communication module 104 is used for remote interaction with the remote control terminal, enabling multi-point bus control. That is, the engagement or disengagement of multiple pressure plates on the protection and control panel can be centrally controlled through the remote control terminal. The wireless carrier power supply communication module 105 enables wireless interaction with external handheld devices, enabling single-point control on site. That is, the operator can wirelessly interact with a specific pressure plate on site through a handheld device to achieve single-point control of a pressure plate.

[0038] In summary, this effectively solves the problems of large quantities being concentrated and prone to omissions and misoperations; the operation of this pressure plate is simpler and safer, improving work efficiency, and the collection and transmission of pressure plate activation and deactivation status data can greatly improve inspection efficiency.

[0039] Specifically, one working mode of this embodiment is as follows: Among the multiple pressure plates on the protection and control panel, each pressure plate detects its current engaged or disengaged state through the status detection module 103 and transmits it to the remote control terminal through the remote communication module 104. The remote control terminal can then obtain the engaged or disengaged state of all pressure plates. When it is necessary to control one or more of the multiple pressure plates to change their current state, the remote control terminal issues a corresponding command. After receiving the command, the corresponding pressure plate controls the motor drive module 102 through the main control module 101 to drive the motor 30 to switch the engaged or disengaged state of the pressure plate body 1, thus realizing multi-point bus control. At the same time, the field operator can connect to a single pressure plate through a handheld device. The connected pressure plate achieves wireless interaction through the wireless carrier power supply communication module 105 to upload the current state of the pressure plate. When a switch is required, the operator directly issues a command through the handheld device. After receiving the command, the connected pressure plate controls the motor drive module 102 through the main control module 101 to drive the motor 30 to switch the engaged or disengaged state of the pressure plate body 1, thus realizing single-point control of a certain pressure plate.

[0040] Specifically, in this embodiment, the state detection module 103 is a Hall sensor. For example, a Hall sensor and a magnet are respectively installed at the positions of the conductive swing arm 21 and the stationary contact 22 of the pressure plate body 1. When the conductive swing arm 21 switches to the closed position contacting the stationary contact 22, the Hall sensor is triggered and outputs a signal to the main control module 101. When the conductive swing arm 21 switches to the open position, it moves away from the magnet and loses its triggering function. This achieves accurate detection of the engagement / disengagement state of the pressure plate body 1. Of course, in other embodiments, the state detection module 103 can also use other modules capable of detection, such as a limit switch. The limit switch is located near the stationary contact 22, and when the conductive swing arm 21 switches to the closed position contacting the stationary contact 22, the limit switch is triggered synchronously.

[0041] In this embodiment, the remote communication module 104 is an RS485 communication module. Of course, in other embodiments, other wired or wireless communication modules that can be used for remote communication can also be used.

[0042] Furthermore, it also includes an indicator module 106, which is connected to the main control module 101 for indicating the status of the pressure plate body 1. In this embodiment, the indicator module 106 is an LED indicator. For example, when the pressure plate body 1 is in the engaged state, the main control module 101 controls the LED indicator to emit green light for indication; when the pressure plate body 1 is in the disengaged state, the main control module 101 controls the LED indicator to emit red light for indication. Of course, in other embodiments, the indicator module 106 can also be other things such as a pointer, and the main control module 101 achieves indication by controlling the pointer to swing.

[0043] Specifically, the pressure plate supports active and passive modes. In active mode, an external power supply module supplies power to the main control module 101, motor drive module 102, status detection module 103, wireless carrier power supply communication module 105, remote communication module 104, and indicator module 106. In passive mode, the wireless carrier power supply communication module 105 is connected to an external power supply and supplies power to at least one of the following power supply modules: main control module 101, motor drive module 102, status detection module 103, remote communication module 104, and indicator module 106.

[0044] Specifically, in this embodiment, the pressure plate body 1 includes a first conductive terminal 11, a second conductive terminal 12, a conductive swing arm 21, a stationary contact 22, a motor 30, and an insulating transmission component 31. The first conductive terminal 11 and the second conductive terminal 12 are spaced apart for connecting external conductive components (such as...). Figure 7The conductive pin 2 shown makes the pressure plate body 1 part of the electrical circuit of the protection device. One end of the conductive swing arm 21 is rotatably connected to the first conductive terminal 11, and the stationary contact 22 is connected to the second conductive terminal 12. The motor 30 drives the conductive swing arm 21 through the insulating transmission component 31 to drive the conductive swing arm 21 to the closed position where it is in electrical contact with the stationary contact 22 (e.g., Figure 5 (as shown) and the disconnected position separated from the stationary contact 22 (as shown) Figure 6 The conductive swing arm 21 swings between the closed and open positions. When the conductive swing arm 21 is in the closed position, the electrical circuit of the corresponding protection device is connected, and the protection function is in normal working condition. That is, the corresponding function is activated, indicating that the pressure plate body 1 is in the activated state. When the conductive swing arm 21 is in the open position, the electrical circuit of the corresponding protection device is disconnected, and the protection function no longer works. That is, the corresponding function is deactivated, indicating that the pressure plate body 1 is in the deactivated state.

[0045] The conductive swing arm 21 is driven by the motor 30. That is, the closing and opening operations of the conductive swing arm 21 are both driven by the motor 30, realizing electric control. As long as the motor 30 is controlled to rotate, the position of the conductive swing arm 21 can be well controlled without manual operation. In addition, the conductive swing arm 21 can not only swing to switch, but also be stably held in the open or closed position by the holding of the motor 30. The pressure plate body 1 has the advantages of rapid and reliable switching action.

[0046] Meanwhile, the motor 30 drives the conductive swing arm 21 through the insulating transmission component 31, and insulation is formed between the motor 30 and the conductive swing arm 21 to ensure that the motor 30 is not affected.

[0047] When the conductive swing arm 21 is disconnected, it faces the first side direction (e.g.) Figure 5 and Figure 6 The outward swing (facing downwards) can be understood as follows: taking the position of the conductive swing arm 21 in the closed position as boundary line a, the opening and closing of the conductive swing arm 21 can only be switched in this first side direction (i.e., below boundary line a), and cannot reach the other side of boundary line a (i.e., the second side opposite to the first side, such as...). Figure 5 and Figure 6 Since the motor 30 is located on the upper side, it is positioned on the second side opposite to the first side and will not interfere with the switching action of the conductive swing arm 21.

[0048] The insulated transmission component 31 is an insulated gear transmission assembly. The motor 30 and the conductive swing arm 21 are transmitted through the insulated gear transmission assembly, which is stable and reliable. The motor 30 can be on the same layer as the conductive swing arm 21 or the first conductive terminal 11, thereby reducing the thickness of the pressure plate body 1.

[0049] Specifically, in this embodiment, the gear transmission assembly includes a reduction gear set 32, a bushing 33, and a driven gear 34. The first conductive terminal 11 has a fixed post 111, which is cylindrical. The bushing 33 is rotatably fitted onto the fixed post 111. The conductive swing arm 21 is fixed to the bushing 33, forming a rotatable configuration. The conductive swing arm 21 contacts the outer surface of the fixed post 111 and is electrically connected to the first conductive terminal 11. The driven gear 34 is fixed to the bushing 33. The rotating shaft of the motor 30 is connected to the reduction gear set 32, and the reduction gear set 32 ​​meshes with the driven gear 34. The forward and reverse rotation of the motor 30 drives the driven gear 34 and the bushing 33 to rotate through the reduction gear set 32. The rotation of the bushing 33 drives the conductive swing arm 21 to swing open and close. The reduction gear set 32 ​​increases the torque of the conductive swing arm 21, making its switching and holding in a fixed position more reliable.

[0050] The bushing 33 and the driven gear 34 are integrally connected. The bushing 33 is integrally wrapped and fixed to the conductive swing arm 21 by injection molding. That is, during the preparation, the conductive swing arm 21 is first placed in the injection mold, and then the bushing 33 and the driven gear 34 are directly injection molded through the injection mold, which also fixes the bushing 33 and the conductive swing arm 21, so that the bushing 33, the driven gear 34 and the conductive swing arm 21 form an integral part.

[0051] Of course, other embodiments are not limited to this. For example, to better ensure electrical contact between the conductive swing arm 21 and the fixed post 111, the bushing 33 can also be divided into an inner bushing and an outer bushing covering the outer circumference of the inner bushing. The inner bushing and the conductive swing arm 21 are integrally connected, that is, the inner bushing is also conductive. The inner bushing is directly sleeved on the fixed post 111 to achieve large-area contact and ensure electrical contact between the conductive swing arm 21 and the fixed post 111. At the same time, the outer bushing and the driven gear 34 are integrally molded by injection molding. Alternatively, the bushing 33, the driven gear 34, and the conductive swing arm 21 can be independent components and fixed by assembly.

[0052] Furthermore, the stationary contact 22 is a spring with a "C" shaped cross-section. When the conductive swing arm 21 is switched to the closed position, it is clamped and fixed by the stationary contact 22. That is, when closed, the conductive swing arm 21 is inserted into the "C" shaped cavity of the spring, which causes the spring to undergo elastic deformation, thereby having a clamping force on the conductive swing arm 21. In this way, the contact between the stationary contact 22 and the conductive swing arm 21 is more reliable in the closed state.

[0053] Furthermore, the second conductive terminal 12 has a mounting step 121, and a spring with a "C"-shaped cross-section is fixedly mounted on the mounting step 121 of the second conductive terminal 12 with its opening facing the conductive swing arm 21, so as to realize the fixation and electrical connection between the second conductive terminal 12 and the stationary contact 22. Specifically, the spring has a connecting hole and is locked onto the second conductive terminal 12 by bolts.

[0054] Furthermore, the system also includes a housing 40. The first conductive terminal 11, the second conductive terminal 12, the motor 30, the conductive swing arm 21, the stationary contact 22, the main control module 101, the motor drive module 102, the status detection module 103, the remote communication module 104, the wireless carrier power supply communication module 105, and the indicator module 106 are all directly or indirectly fixedly mounted on the housing 40. The housing 40 has a receiving cavity 401, in which the conductive swing arm 21 and the stationary contact 22 are located. One side of the housing 40 has a lateral opening 412 for the conductive swing arm 21 to move. In actual use, the front of the housing 40 (i.e., the upper cover 42 below) faces the operator. The conductive swing arm 21 swings and switches in the lateral direction. When the conductive swing arm 21 switches from the closed position to the open position, the conductive swing arm 21 will extend out of the housing 40 through the lateral opening 412. By confirming whether the conductive swing arm 21 extends out of the housing 40, the state of the conductive swing arm 21 can be directly determined. The housing 40 allows the pressure plate body 1 to form an integral structure, which can be pre-assembled and then uniformly assembled onto the application equipment (such as the protective cabinet below).

[0055] Specifically, the shell 40 is made of a transparent insulating material, which has a visual effect and allows for direct confirmation of the internal structure.

[0056] Furthermore, the housing 40 includes a bottom shell 41 and a top cover 42. The bottom shell 41 has a receiving groove. The first conductive terminal 11, the second conductive terminal 12, and the motor 30 are all fixedly mounted on the bottom shell 41. The conductive swing arm 21 and the stationary contact 22 are both located in the receiving groove of the bottom shell 41. The top cover 42 is detachably closed on the upper opening of the receiving groove of the bottom shell 41 to enclose the receiving groove and form the receiving cavity 401. The lateral opening 412 is provided on one side wall of the bottom shell 41. This arrangement facilitates assembly.

[0057] Furthermore, the bottom of the housing 40 is provided with two insertion holes 413 that are respectively connected to the first conductive terminal 11 and the second conductive terminal 12.

[0058] Both the first conductive terminal 11 and the second conductive terminal 12 have insertion holes 413 at their bottoms; for example Figure 6As shown, the pressure plate body 1 is fixedly connected to the conductive pin 2 on the protective cabinet through the insertion hole 413.

[0059] With this setup, in practical applications, the conductive pin 2 can be fixed on the protective cabinet first, and then the pressure plate body 1 can be inserted into the conductive pin 2 to fix the pressure plate body 1 and make electrical connection. When maintenance or replacement is required, the pressure plate body 1 can be pulled out directly, which is simple to operate.

[0060] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
