Abstract
Description
Technical Field
[0001] This utility model relates to the field of controller technology, specifically to an intelligent controller instrument with safety protection functions. Background Technology
[0002] A controller is a control device used in the field of industrial automation to monitor and manage equipment and systems in the production process. A DCS system typically consists of multiple distributed controllers that are connected via a network and communicate with sensors, actuators and other control devices.
[0003] For example, patent CN222283799U discloses a DCS controller with safety protection function, specifically relating to the field of DCS controller technology. It includes a DCS controller body, a protective base plate fixedly connected to the bottom of the DCS controller body, a fixing slot on the top surface of the protective base plate, and a protective heat dissipation mechanism on the top of the DCS controller body. The protective heat dissipation mechanism includes a protective shell, which is hinged to the protective base plate. This utility model, by setting up a protective heat dissipation mechanism, prevents the DCS controller body from being directly impacted by external forces, providing a certain degree of protection while also providing good heat dissipation. It dissipates heat while providing protection, and simultaneously prevents dust from entering, protecting the equipment from the influence of the external environment. The dust-adhesive plate absorbs dust, improving the dustproof effect and preventing dust from adversely affecting electronic components, thus extending the service life of the electronic components.
[0004] However, the aforementioned DCS controller with safety protection function, after the protective outer box is placed over the outer surface of the controller, cannot automatically press the controller into the protective shell to avoid accidental shaking and impact, nor can it block the heat dissipation holes of the protective shell to prevent the spread of fire after an internal or external fire. Utility Model Content
[0005] The purpose of this utility model is to provide an intelligent controller instrument with safety protection function to solve the problems mentioned in the background art, which are that after the protective outer box is covered on the outer surface of the controller, it cannot automatically press the controller into the protective outer shell, and it cannot block the heat dissipation holes of the protective outer shell to prevent the spread of fire after a fire starts inside or outside.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An intelligent controller instrument with safety protection function includes: a protective box, a top cover rotatably mounted on the upper surface of the protective box, a pressure contact mechanism fixedly mounted on the lower surface of the top cover, the pressure contact mechanism being able to press against the upper surface of the controller, and the controller being placed inside the protective box.
[0008] Preferably, a latch is fixedly installed at one end of the protective box, the latch head can be fitted onto the outer surface of the latch tongue, and the latch tongue is fixedly installed at one end of the top cover.
[0009] Preferably, a ceramic fiber bag is fixedly installed on the inner ring wall of the protective box. The ceramic fiber bag is filled with sodium sulfate decahydrate. The ceramic fiber bag can surround the outer surface of the controller after installation. The inner surface of the ceramic fiber bag is coated with PTFE.
[0010] Preferably, the pressure contact mechanism includes a connecting cylinder, which is fixedly installed at one end of the top cover. A connecting column is slidably installed inside the connecting cylinder, and a pressure plate is fixedly installed at one end of the connecting column.
[0011] Preferably, a guide block is fixedly installed on the outer surface of the connecting column, and the guide block is slidably installed in the guide groove, which is formed on the outer surface of the connecting cylinder.
[0012] Preferably, a rectangular spring is fixedly connected to one end of the connecting cylinder, and the other end of the rectangular spring is fixedly connected to one end of the connecting post, so that the connecting post can press against the upper surface of the controller by the elastic force applied by the rectangular spring.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Through the design of the protective box, top cover, ceramic fiber bag and pressure contact mechanism, when in use, the controller can be placed in the protective box, and the pressure contact mechanism fixedly installed on the bottom can be driven by flipping the top cover to press against the upper surface of the controller through elastic force. After the top cover is closed, the lock head of the latch can be locked onto the outer surface of the lock tongue to close the top cover. At the same time, the controller pressed by the pressure contact mechanism can be firmly fixed in the protective box to prevent it from being displaced or shaking due to vibration or other external forces during equipment operation, thus ensuring the normal operation of the controller.
[0015] The ceramic fiber bags inside the protective enclosure, filled with sodium sulfate decahydrate, undergo a phase change when heated to a liquid state, filling the ceramic fiber bags. The PTFE coating on the inner surface of the ceramic fiber bags maintains their high-temperature resistance while providing excellent waterproof and water-locking capabilities, preventing the liquid sodium sulfate decahydrate from seeping out. The filled ceramic fiber bags then naturally hang down to block the ventilation openings of the protective enclosure, creating a relatively sealed space inside to prevent the spread of flames from inside or outside. Both the ceramic fiber bags and sodium sulfate decahydrate have a certain degree of flame retardancy, which can slow the spread of fire in the event of a fire and reduce the risk of damage to the equipment inside the protective enclosure and the surrounding environment.
[0016] 2. Through the design of the connecting cylinder, connecting column, rectangular spring, and pressure plate, after the controller is placed inside the protective box, flipping the top cover causes the connecting column, which is slidably installed inside the connecting cylinder on the lower surface, to press against the upper surface of the controller via the pressure plate. As the top cover continues to flip and close, the pressure plate, already pressing against the upper surface of the controller, slides into the connecting cylinder via the connecting column. During this sliding process, it also presses against one end of the rectangular spring, which then applies a spring force to the connecting column. This spring force causes the connecting column to press the pressure plate against the upper surface of the controller, thus ensuring that the pressure on the controller remains within a suitable range. To prevent the controller from becoming loose due to insufficient pressure or being damaged by excessive pressure, the rectangular spring acts as a buffer when the controller is subjected to vibration or external impact during operation. When there is vibration or impact, the connecting column will slide accordingly within the connecting cylinder, absorbing some of the energy and reducing the vibration and impact force transmitted to the controller. This protects the internal components of the controller from damage and improves the reliability and stability of the controller in harsh working environments. Furthermore, when the controller needs to be disassembled for maintenance or replacement, simply open the top cover, and the elasticity of the rectangular spring will cause the connecting column to automatically reset, making it easy to remove the controller. The entire process does not require additional tools, improving work efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-3 This utility model provides a technical solution:
[0023] like Figures 1-2 As shown, an intelligent controller instrument with safety protection function includes: a protective box 1, a top cover 101 rotatably mounted on the upper surface of the protective box 1, a pressing mechanism 2 fixedly mounted on the lower surface of the top cover 101, the pressing mechanism 2 being able to press against the upper surface of the controller 105, and the controller 105 being placed inside the protective box 1.
[0024] A latch 102 is fixedly installed at one end of the protective box 1. The latch head of the latch 102 can be fitted onto the outer surface of the latch tongue 103. The latch tongue 103 is fixedly installed at one end of the top cover 101.
[0025] A ceramic fiber bag 104 is fixedly installed on the inner ring wall of the protective box 1. The ceramic fiber bag 104 is filled with sodium sulfate decahydrate. The ceramic fiber bag 104 can surround the outer surface of the controller 105 after installation. The inner surface of the ceramic fiber bag 104 is coated with PTFE.
[0026] Through the design of the protective box 1, top cover 101, ceramic fiber bag 104 and pressure contact mechanism 2, when in use, the controller 105 can be placed in the protective box 1, and the pressure contact mechanism 2 fixedly installed on the lower surface can be driven to press against the upper surface of the controller 105 by flipping the top cover 101. After the top cover 101 is closed, the lock head of the latch 102 can be locked onto the outer surface of the latch tongue 103 to close the top cover 101. At the same time, the controller 105 pressed by the pressure contact mechanism 2 can be firmly fixed in the protective box 1, preventing it from being displaced or shaking due to vibration or other external forces during equipment operation, and ensuring the normal operation of the controller 105.
[0027] The sodium sulfate decahydrate, filled in the ceramic fiber bag 104 inside the protective box 1, undergoes a phase change when heated to a liquid state, filling the ceramic fiber bag 104. The PTFE coating on the inner surface of the ceramic fiber bag 104 maintains the bag's high-temperature resistance while providing excellent waterproof and water-locking capabilities, preventing the liquid sodium sulfate decahydrate from seeping out. The filled ceramic fiber bag 104 then hangs down naturally to block the heat dissipation vents of the protective box 1, thus creating a relatively sealed space inside the protective box 1 to prevent the spread of flames from inside or outside. Both the ceramic fiber bag 104 and the sodium sulfate decahydrate have certain flame-retardant properties, which can delay the spread of fire in the event of a fire and reduce the risk of damage to the equipment inside the protective box 1 and the surrounding environment.
[0028] like Figure 3As shown, the pressure contact mechanism 2 includes a connecting cylinder 201, which is fixedly installed at one end of the top cover 101. A connecting column 203 is slidably installed inside the connecting cylinder 201, and a pressure plate 205 is fixedly installed at one end of the connecting column 203.
[0029] A guide block 206 is fixedly installed on the outer surface of the connecting column 203. The guide block 206 is slidably installed in the guide groove 202, which is opened on the outer surface of the connecting cylinder 201.
[0030] A rectangular spring 204 is fixedly connected to one end of the connecting cylinder 201, and the other end of the rectangular spring 204 is fixedly connected to one end of the connecting post 203, so that the connecting post 203 can press against the upper surface of the controller 105 by the elastic force applied by the rectangular spring 204.
[0031] Through the design of the connecting cylinder 201, connecting post 203, rectangular spring 204, and pressure plate 205, after the controller 105 is placed inside the protective box 1, the connecting post 203, which is slidably installed inside the connecting cylinder 201 on the lower surface, can be pressed against the upper surface of the controller 105 by flipping the top cover 101. As the top cover 101 continues to flip and close, the pressure plate 205, which is already pressing against the upper surface of the controller 105, can slide into the connecting cylinder 201 through the connecting post 203. During the sliding process, it will also press against one end of the rectangular spring 204, thereby allowing the rectangular spring 204 to apply a spring-like pushing force to the connecting post 203. This spring-like pushing force allows the connecting post 203 to drive the pressure plate 205 to press against the upper surface of the controller 105, thus ensuring that the controller 105 is subjected to pressure. The force is always kept within a suitable range to prevent the controller 105 from being loosely fixed due to insufficient pressure or damaged due to excessive pressure. When the controller 105 is subjected to vibration or external impact during operation, the rectangular spring 204 can act as a buffer. When there is vibration or impact, the connecting column 203 will slide accordingly in the connecting cylinder 201 and absorb some energy, reducing the vibration and impact force transmitted to the controller 105, thereby protecting the internal components of the controller 105 from damage and improving the reliability and stability of the controller 105 in harsh working environments. Furthermore, when the controller 105 needs to be disassembled for maintenance or replacement, it is only necessary to open the top cover 101. The elasticity of the rectangular spring 204 will cause the connecting column 203 to automatically reset, making it easy to remove the controller 105. The whole process does not require the use of additional tools, which improves work efficiency.
[0032] Based on the above technical solution, the working steps of this solution are summarized as follows: In use, the controller 105 can be placed inside the protective box 1. By flipping the top cover 101, the connecting post 203, which is slidably installed inside the connecting cylinder 201 on the lower surface, is pressed against the upper surface of the controller 105 by the pressure plate 205. As the top cover 101 continues to flip and close, the pressure plate 205, which is already pressed against the upper surface of the controller 105, slides into the connecting cylinder 201 through the connecting post 203. During this sliding process, it will press against one end of the rectangular spring 204, thereby allowing the rectangular spring 204 to apply a spring-like pushing force to the connecting post 203. This spring-like pushing force causes the pressure plate 205 to press against the upper surface of the controller 105. After the top cover 101 is closed, the operator can lock the latch 102 onto the outer surface of the latch 103 to close the top cover 101. Furthermore, when the controller 105 needs to be disassembled for maintenance or replacement, only the top cover 101 needs to be opened. The elastic force of the rectangular spring 204 will cause the connecting column 203 to automatically reset, making it easy to remove the controller 105. The entire process does not require the use of additional tools, which improves work efficiency. The sodium sulfate decahydrate filled in the ceramic fiber bag 104 set inside the protective box 1 can undergo a phase change when heated at high temperature, changing from a solid to a liquid state to fill the ceramic fiber bag 104. The PTFE coating on the inner surface of the ceramic fiber bag 104 can obtain excellent waterproof and water-locking ability while maintaining the bag's high temperature resistance characteristics, which can prevent the sodium sulfate decahydrate, which has turned into liquid, from seeping out. The filled ceramic fiber bag 104 can then hang down naturally to block the heat dissipation vents of the protective box 1, thereby making the interior of the protective box 1 a relatively sealed space to prevent the spread of internal or external flames and reduce the risk of fire damage to the equipment inside the protective box 1 and the surrounding environment.
[0033] In summary: This design allows the controller 105 to be securely fixed inside the protective enclosure 1, preventing it from shifting or shaking due to vibration or other external forces during equipment operation, ensuring the normal operation of the controller 105. Furthermore, in the event of a fire, the heat dissipation vents of the protective enclosure 1 can be blocked, thus creating a relatively sealed space inside the enclosure 1 to prevent the spread of internal or external flames, thereby reducing the risk of fire damage to the equipment inside the protective enclosure 1 and the surrounding environment.
