Description

Technical Field

[0001] This utility model relates to the technical field of equipment protection, and in particular to a security protection device for an auxiliary control network DCS system. Background Technology

[0002] In the field of modern industrial automation, the DCS (Distributed Control System) plays a crucial role in the centralized monitoring and decentralized control of industrial production processes. Its operational stability and security directly impact the efficiency and quality of the entire industrial production. A DCS system integrates numerous precision electronic components, which generate significant heat during operation. Failure to dissipate this heat in a timely manner will lead to performance degradation and even system malfunctions. Furthermore, dust and other impurities entering the electrical enclosure not only adhere to the surfaces of electronic components, hindering heat dissipation, but may also cause serious problems such as short circuits, threatening the normal operation of the system.

[0003] However, various electronic components in a DCS system generate a significant amount of heat during operation. These components typically have strict requirements regarding operating temperature. Excessive temperature can not only affect the performance and stability of the components, leading to data transmission errors and reduced control accuracy, but it can also shorten their lifespan, or even cause damage, ultimately resulting in a malfunction of the entire DCS system and disrupting normal industrial production. Therefore, effective heat dissipation measures are crucial for ensuring the reliable operation of a DCS system.

[0004] Meanwhile, the environment at industrial production sites is often complex, containing a large amount of dust, particulate matter, and other impurities. Once these impurities enter the electrical box of a DCS system and adhere to the surface of electronic components, they may affect the heat dissipation of the components, leading to localized temperature increases; they may also cause safety hazards such as short circuits and decreased insulation performance, seriously threatening the safe and stable operation of the DCS system.

[0030] In the above technical solution, the security protection device for the auxiliary control network DCS system provided by this utility model has the following beneficial effects:

[0031] This safety protection device, through the installation of a filter heat dissipation cover, effectively dissipates heat from inside the electrical box. While ensuring air circulation, it transfers heat to the external environment, preventing problems such as performance degradation of electronic components, data transmission errors, reduced control precision, and system malfunctions caused by excessively high internal temperatures. This ensures the reliable operation of the DCS system, thereby improving the efficiency and quality of industrial production. The filter heat dissipation cover effectively blocks dust, particulate matter, and other impurities from entering the electrical box, preventing dust from adhering to the surface of electronic components and affecting heat dissipation.

[0038] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0039] See Figure 1-4 As shown;

[0040] The security protection device of the auxiliary control network DCS system in this embodiment of the utility model includes:

[0041] Electrical box 1, with a component mounting cavity inside;

[0042] The filter and heat dissipation mechanism 2 is covered and installed on the top of the electrical box 1 to dissipate heat from the electrical box 1 and prevent dust from entering.

[0043] Support mechanism 3 is set on the ground to support electrical box 1;

[0044] The heat dissipation and filtration mechanism 2 includes:

[0045] Screw bracket 21 is fixedly installed inside electrical box 1;

[0046] Adjusting screw 22 is rotatably mounted on screw bracket 21;

[0047] Top cover 23 is threaded onto adjusting screw 22. Top cover 23 is raised and lowered at the top of electrical box 1, and its height is adjusted by adjusting screw 22.

[0048] The filter heat dissipation cover 24 is fixedly installed at the bottom of the top cover 23, and the filter heat dissipation cover 24 is slidably inserted into the top of the electrical box 1.

[0049] Two limiting plates 25 are symmetrically arranged on the outer wall of the electrical box 1;

[0050] Two support plates 26 are symmetrically arranged on both sides of the top cover 23. The support plates 26 cooperate with the limiting support plate 25 to limit the downward movement of the filter heat dissipation cover 24.

[0051] By adopting the above technical solution, the heat dissipation filter 24 is fixedly installed at the bottom of the top cover 23 and slidably inserted into the top of the electrical box 1. When the electronic devices in the DCS system generate heat during operation, the internal temperature of the electrical box 1 rises. At this time, the heat is dissipated to the external environment through the heat dissipation filter 24. The heat dissipation filter 24 has a certain ventilation structure, which can ensure air circulation, thereby realizing the heat dissipation function. At the same time, the heat dissipation filter 24 has a filtering function. When dust, particulate matter, and other impurities in the industrial production environment attempt to enter the electrical box 1, they will be blocked by the heat dissipation filter 24, effectively preventing dust and other impurities from entering the electrical box 1 and adhering to the surface of the electronic devices, avoiding the impact on the heat dissipation effect and potential short circuits and other safety issues. Potential hazards: During long-term use, the filter heat dissipation cover 24 may accumulate a certain amount of dust, affecting its heat dissipation and filtration performance. In this case, the height of the top cover 23 can be adjusted by rotating the adjusting screw 22. Since the top cover 23 is threaded onto the adjusting screw 22, and the filter heat dissipation cover 24 is fixedly installed at the bottom of the top cover 23, the top cover 23 will rise or fall along the adjusting screw 22 when the adjusting screw 22 is rotated. The symmetrically arranged support plates 26 on both sides of the top cover 23 cooperate with the symmetrically arranged limiting plates 25 on the outer wall of the electrical box 1 to limit the downward movement of the filter heat dissipation cover 24, ensuring that the filter heat dissipation cover 24 will not move excessively downward and deviate from its normal working position during adjustment. By adjusting the top cover 23 to rise, the filter heat dissipation cover 24 can be moved from the electrical box 1 to the upper part of the electrical box 1. The top part of box 1 can be pulled out for easy cleaning and maintenance of the filter heat dissipation cover 24. After cleaning, the adjusting screw 22 is rotated in the opposite direction to lower the top cover 23, and the filter heat dissipation cover 24 is reinserted into the top of the electrical box 1 to restore its normal working state. This safety protection device, by setting up the filter heat dissipation cover 24, can effectively dissipate heat inside the electrical box 1. While ensuring air circulation, it transfers heat to the external environment, avoiding problems such as performance degradation of electronic components, data transmission errors, reduced control accuracy, and system failures caused by excessive internal temperature of the electrical box 1. This ensures the reliable operation of the DCS system, thereby improving the efficiency and quality of industrial production. The filtration function of the filter heat dissipation cover 24 can effectively block dust, particulate matter, and other impurities from entering the electrical box. Inside Box 1, dust adheres to the surface of electronic components, preventing it from affecting heat dissipation and avoiding localized temperature increases due to dust accumulation. This also reduces the probability of safety hazards such as short circuits and decreased insulation performance, providing strong protection for the safe and stable operation of the DCS system. An adjustment mechanism consisting of an adjusting screw 22, a top cover 23, a limit plate 25, and a support plate 26 allows for easy adjustment of the height of the filter heat dissipation cover 24. When cleaning or maintenance of the filter heat dissipation cover 24 is required, simply rotate the adjusting screw 22 to partially remove the cover; there is no need to disassemble the entire electrical box 1 or other complex components. This significantly reduces maintenance difficulty and cost, improves equipment maintainability, and extends the equipment's service life.

[0052] As a preferred embodiment of the above technical solution, such as Figures 1 to 2 As shown, several guide strips 27 are vertically arranged on the inner side wall of the electrical box 1, and several guide grooves are arranged on the outer side wall of the filter heat dissipation cover 24. The filter heat dissipation cover 24 is slidably mounted on the electrical box 1 through the sliding cooperation of each guide groove and the guide strips 27.

[0053] In this embodiment, the cooperation between the guide strip 27 and the guide groove provides precise guidance for the installation and sliding of the filter heat sink 24, ensuring the sealing and relative position accuracy between the filter heat sink 24 and the electrical box 1. This allows heat to be dissipated more stably through the filter heat sink 24, while dust and other impurities are more effectively blocked, improving the stability and reliability of heat dissipation and dust prevention. When cleaning and maintaining the filter heat sink 24, the cooperation between the guide strip 27 and the guide groove makes the extraction and insertion of the filter heat sink 24 smoother and more precise. This avoids collisions or damage to internal components of the electrical box 1 caused by the filter heat sink 24 shifting or shaking, reducing the risk of malfunctions during maintenance and improving the safety and convenience of maintenance operations. The stable guiding and cooperating structure reduces wear and vibration of the filter heat sink 24 during sliding, reducing damage to the filter heat sink 24 and the electrical box 1 caused by mechanical stress. At the same time, the good heat dissipation and dust prevention effect also helps protect the electronic components inside the electrical box 1, extending the service life of the entire DCS system safety protection device and the DCS system.

[0054] As a preferred embodiment of the above technical solution, such as Figure 3 As shown, each support plate 26 is provided with two first springs 28 at its bottom end, and a buffer plate 29 is provided at the bottom end of each first spring 28;

[0055] In this embodiment, the filter heat sink 24 may experience significant impact due to improper operation or external factors during its vertical movement. The buffer structure can cushion this impact, preventing the filter heat sink 24 from violently colliding with the electrical box 1, protecting the structural integrity of the electrical box 1, the filter heat sink 24, and related connecting components, and extending the service life of the device. Without a buffer structure, external vibrations or vibrations caused by component movement would lead to noise from collisions between components. The buffering effect of the first spring 28 and the buffer plate 29 can reduce such collisions, thereby reducing noise during device operation and improving noise pollution in the industrial production environment. The presence of the buffer structure allows the device to maintain a relatively stable state when facing external interference, providing a more stable working environment for the DCS system and helping to improve the accuracy and reliability of system control.

[0056] As a preferred embodiment of the above technical solution, a noise-reducing pad is adhesively attached to the bottom of the buffer plate 29.

[0057] In this embodiment, when the support plate 26 comes into contact with components such as the limiting plate 25, the rigid collision between the components will generate significant noise. The noise-reducing rubber pad has excellent sound absorption and insulation properties. It can absorb and disperse the sound wave energy generated by the collision at the moment of contact, effectively reducing the noise level generated by the collision, providing a relatively quiet working environment for the industrial production site, reducing noise interference to operators, and improving work comfort. The noise-reducing rubber pad itself has a certain degree of elasticity and softness, which can further increase the buffering effect when in contact with components such as the limiting plate 25. Compared with simply relying on the first spring 28 for buffering, the noise-reducing rubber pad can more evenly disperse the impact force, reduce local stress concentration, and thus better protect the support plate 26, the limiting plate 25, and other related components, avoiding damage to components caused by excessive impact force and extending the service life of the device.

[0058] As a preferred embodiment of the above technical solution, such as Figures 1 to 3 As shown, the outer end of the adjusting screw 22 is equipped with an anti-slip handle;

[0059] In this embodiment, the anti-slip handle effectively increases the friction between the hand and the adjusting component, preventing operational errors caused by hand slippage during adjustment. This ensures that the operator can accurately control the rotation angle and number of turns of the adjusting screw 22, thereby accurately adjusting the height of the filter heat sink 24 and ensuring the stable operation of the heat dissipation system. Compared to the smooth end of the adjusting screw, the anti-slip handle is easier to grip, conforms to ergonomic design, and can effectively reduce operator fatigue. Even during prolonged adjustment operations, it maintains a good feel for operation, allowing the operator to complete the adjustment of the heat dissipation system more easily and conveniently. The stable grip and smooth rotation operation reduce ineffective movements and repetitive adjustments during the adjustment process, enabling the filter heat sink 24 to be adjusted to the appropriate height quickly and accurately, improving the adjustment efficiency of the heat dissipation system. In case of emergency heat dissipation needs or equipment debugging, the operation can be completed more quickly, ensuring that the DCS system obtains suitable heat dissipation conditions in a timely manner.

[0060] As a preferred embodiment of the above technical solution, such as Figure 1 and Figure 4 As shown, the support mechanism 3 includes:

[0061] Two shafts 31 are fixedly installed at the bottom of the electrical box 1;

[0062] Two buffer support plates 32 are respectively oscillatingly mounted on two shafts 31;

[0063] Two hinge seats 33 are respectively hinged to the bottom ends of two buffer support plates 32;

[0064] Two load-bearing support rods 34 are slidably coupled with two hinge seats 33. Each load-bearing support rod 34 is fitted with two second springs 36, which are located on the outside of the hinge seat 33.

[0065] The base 35 is supported on the ground, and two load-bearing support rods 34 are fixedly installed on the base 35. The outer end of the second spring 36 is attached to the side wall of the base 35.

[0066] In this embodiment, during normal operation of the DCS system, the electrical box 1 is stably supported on the support mechanism 3 by two shafts 31 at its bottom end and a buffer support plate 32 oscillatingly mounted on the shafts 31. The bottom end of the buffer support plate 32 is hinged to the hinge seat 33, which is slidably fitted onto the load-bearing support rod 34 fixed on the base 35. At this time, the second spring 36 is in a certain preloaded state, providing support for the hinge seat 33 and the buffer support plate 32, keeping the electrical box 1 at a stable height and position, and ensuring the electronic components inside the DCS system are in good working order. The device functions normally; when external interference such as vibration or collision occurs on site, the electrical box 1 will be subjected to upward impact or downward pressure; the buffer support plate 32 will swing around the shaft 31, causing the hinge seat 33 to slide along the load-bearing support rod 34; at this time, the second spring 36 located on the outside of the hinge seat 33 is compressed or stretched, producing elastic deformation, absorbing and buffering the impact energy, preventing the electrical box 1 from shaking violently or being damaged due to excessive impact force; the second spring 36 in the support mechanism 3 can effectively absorb and buffer the vibration and impact generated on the industrial production site. The impact force is reduced, minimizing the influence of external factors on the electrical box 1 and its internal electronic components. The elastic deformation of the second spring 36 converts impact energy into elastic potential energy, thereby reducing the swaying amplitude of the electrical box 1, preventing damage to electronic components due to severe vibration, and improving the stability and reliability of the DCS system. The buffer support plate 32 is oscillatingly mounted on the shaft 31 and hinged to the hinge seat 33, which in turn slides on the load-bearing support rod 34. This structure gives the support mechanism 3 a certain degree of self-adjustment capability. Regardless of the direction of impact or pressure on the electrical box 1, the support mechanism 3 can buffer and adjust through the relative movement of its components and the elastic deformation of the second spring 36, always maintaining stable support for the electrical box 1 and adapting to different working environments and conditions. Because the support mechanism 3 can effectively buffer external impacts and vibrations, it reduces the mechanical stress on the electrical box 1 and its internal electronic components, thereby reducing the risk of damage to components due to fatigue, wear, etc. This helps extend the service life of the DCS system, reduce maintenance and replacement costs, and improve the economic efficiency of industrial production.

[0067] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, four guide sleeves 37 are provided on the base 35, and four guide posts 38 are provided at the bottom of the electrical box 1. The four guide posts 38 are slidably inserted into the four guide sleeves 37 respectively.

[0068] In this embodiment, the cooperation between the guide post 38 and the guide sleeve 37 provides precise positioning for the installation of the electrical box 1, ensuring that the electrical box 1 is accurately positioned on the base 35. This helps to ensure the installation accuracy and layout rationality of the electronic components inside the DCS system, avoiding problems such as wiring connection issues and poor heat dissipation caused by deviations in the installation position of the electrical box 1, thereby improving the overall performance and reliability of the system. When the electrical box 1 is subjected to external interference, the sliding of the guide post 38 within the guide sleeve 37 can limit the horizontal shaking of the electrical box 1, allowing it to only make small vertical displacements. This limiting effect effectively reduces the shaking amplitude of the electrical box 1, improves its stability, and protects the internal electronic components from mechanical damage caused by violent shaking, ensuring the normal operation of the DCS system.

[0069] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, four omnidirectional casters 39 are provided at the bottom of the base 35;

[0070] In this embodiment, four omnidirectional casters 39 enable the safety protection device of the auxiliary control network DCS system to flexibly adjust its position according to actual production needs. In industrial production sites, the production layout may be adjusted according to factors such as process improvements and equipment upgrades. This device can be easily moved to a new suitable location without reinstallation or large-scale modifications, greatly improving the adaptability and flexibility of the device. Compared with traditional devices that require multiple people to move or use large lifting equipment, this device can be easily moved by a small number of operators with the help of the omnidirectional casters 39, saving a lot of labor costs. At the same time, the moving process is faster and more efficient, enabling the device to be quickly deployed to the required location, reducing production downtime caused by equipment movement, and improving the efficiency of industrial production.

[0071] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
