Description

Technical Field

[0001] This utility model relates to the field of instrument component protection technology, specifically a protection device for the installation, maintenance and repair of chemical instrument components. Background Technology

[0002] In chemical production settings, chemical instrumentation serves as a core component for monitoring pipeline media parameters (such as temperature, pressure, and flow rate), and its stable operation directly impacts the safety and accuracy of the production process. However, existing chemical instrumentation components face numerous challenges in practical applications:

[0003] On the one hand, instruments are often directly exposed to the chemical field environment, making them susceptible to dust, water vapor, corrosive gases, and mechanical impacts, which can lead to component damage, decreased measurement accuracy, frequent malfunctions, and shortened service life, increasing maintenance costs.

[0004] On the other hand, the instrument lacks an effective environmental monitoring and early warning mechanism. When abnormalities such as high temperature or toxic gas leakage occur inside the casing, it is difficult to remind staff in time, which can easily lead to safety hazards. At the same time, there is no mandatory protection and control during maintenance, which poses a risk that personnel may operate without wearing compliant protective equipment.

[0005] In addition, the existing protective structure's door panels have a single function, requiring an additional tool placement platform to be built during maintenance, and the door panel fixing and unlocking operations are cumbersome, resulting in low maintenance efficiency and failing to meet the needs of efficient operation and maintenance at chemical sites. Utility Model Content

[0006] The purpose of this utility model is to provide an installation, maintenance and protection device for chemical instrument components to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for the installation, maintenance, and protection of chemical instrument components, comprising: an upper housing and a lower housing installed outside a chemical pipeline, and further comprising: a controller installed on one outer wall of the upper housing, wherein an installation opening is provided on one outer wall of the upper housing, and a door panel is hinged to the bottom inner wall of the installation opening, a monitoring component is installed on one inner wall of the upper housing, and a handle is installed on one outer wall of the door panel, a display component is embedded in the outer wall of the door panel, and limit grooves are provided on both outer walls of the handle, a magnetic lock core is installed on the top outer wall of the door panel, and an installation frame is installed on one outer wall of the lower housing, a sliding rod is installed on the inner wall of the installation frame, and limit components are sleeved at both ends of the sliding rod, and a pressing component is rotatably connected between the two limit components.

[0008] The monitoring components include a mounting plate, temperature sensors and toxic gas sensors mounted on both ends of the outer wall of one side of the mounting plate.

[0009] The display component includes a frame, a transparent viewing window mounted on the inner wall of the frame, and warning lights mounted on both ends of the outer wall of one side of the frame.

[0010] The limiting assembly includes a slider, a spring mounted on one side of the outer wall of the slider, and a plate mounted on the top of the slider.

[0011] The pressing assembly includes connecting rods rotatably mounted on the outer walls of the two insert plates and pressing plates rotatably connected to the tops of the two connecting rods.

[0012] Both of the insert plates have an inclined outer wall structure on opposite sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model discloses a protective device for the installation, maintenance, and repair of chemical instrument components. The upper and lower housings form a closed protective shell, enclosing the instrument and isolating it from dust, moisture, impact, and other interferences, reducing accidental human intervention, minimizing instrument malfunctions, and extending its service life. The monitoring component monitors the internal environment in real time, and an alarm light illuminates when abnormalities occur. The magnetic lock core must be linked with the magnetic tag of the protective equipment for unlocking, enforcing standardized protection and ensuring personnel and production safety. The door panel can be flipped down to serve as a maintenance platform, facilitating tool placement. The limit component fixes the door panel, and the pressing component unlocks it quickly, improving maintenance 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 Figure 1-5 This utility model provides a chemical instrument component installation, maintenance and protection device, including: an upper shell 3 and a lower shell 4 installed outside a chemical pipeline 1, and a controller 5 installed on one side of the outer wall of the upper shell 3. An installation opening is opened on one side of the outer wall of the upper shell 3, and a door panel 6 is hinged to the bottom inner wall of the installation opening. A monitoring component 7 is installed on one side of the inner wall of the upper shell 3, and a handle 8 is installed on one side of the outer wall of the door panel 6. A display component 9 is embedded in the outer wall of the door panel 6, and limit grooves 10 are opened on both sides of the outer wall of the handle 8. A magnetic lock core 11 is installed on the top outer wall of the door panel 6, and an installation frame 12 is installed on one side of the outer wall of the lower shell 4. A sliding rod 13 is installed on the inner wall of the installation frame 12, and limit components 14 are sleeved at both ends of the sliding rod 13. A pressing component 15 is rotatably connected between the two limit components 14.

[0023] It should be noted here that:

[0024] Core protection function: The upper shell 3 and lower shell 4 are installed outside the chemical pipeline 1 to form a closed protective shell, which completely encloses the instrument 2 that needs protection. This can isolate the instrument 2 from interference factors such as dust, water vapor and impact in the external environment, and achieve basic physical protection for the instrument 2.

[0025] Monitoring and control linkage: The monitoring component 7 installed on the inner wall of the upper housing 3 continuously collects environmental data inside the protective housing and transmits the data in real time to the controller 5 installed on the outer wall of the upper housing 3. The controller 5 analyzes and judges the data. When the monitored data (temperature, toxic gas content, etc.) is higher than the preset safety value, the controller 5 triggers the display component 9 embedded on the door panel 6 to start the reminder function. At the same time, personnel can directly observe the status of the instrument 2 inside the protective housing through the display component 9, realizing a closed loop of "monitoring-analysis-early warning-visual observation".

[0026] Security unlocking mechanism: The magnetic lock cylinder 11 at the top of the door panel 6 adopts a magnetic induction unlocking design. Maintenance personnel need to wear a magnetic identification tag (sensor) on their protective equipment (such as gloves and face shields) and bring the sensor close to the sensing area on the surface of the door panel 6 (distance ≤ 5cm). The sensor and the magnetic lock cylinder 11 will send an "unlock signal" through wireless signal linkage to open the door panel 6, thus eliminating the safety hazard of "maintenance without wearing protective equipment" from the source.

[0027] Convenient maintenance support: The door panel 6 can be flipped down via a bottom hinge. After being lowered, the handle 8 on the outer wall of the door panel 6 can be supported on the lower housing 4, keeping the door panel 6 in a horizontal position. At this time, the door panel 6 can serve as a temporary maintenance platform for placing maintenance tools, improving the convenience of maintenance operations. At the same time, two limiting components 14 are fitted on the sliding rod 13 inside the mounting frame 12 on the outer wall of the lower housing 4. After the door panel is lowered, the two limiting components 14 can be respectively engaged in the limiting grooves 10 on both sides of the handle 8, fixing the handle 8 and preventing the door panel 6 from shaking during maintenance. When it is necessary to close the door panel 6, pressing down on the pressing component 15 between the two limiting components 14 can drive the two limiting components 14 to move away from each other along the sliding rod 13 and move out of the limiting grooves 10, releasing the fixation on the handle 8, so that the door panel 6 can be flipped up and closed.

[0028] In a preferred embodiment, the monitoring component 7 includes a mounting plate 701, a temperature sensor 702 and a toxic gas sensor 703 mounted on both ends of the outer wall of one side of the mounting plate 701.

[0029] It should be noted that: temperature sensor 702 is responsible for real-time detection of temperature changes inside the housing, and toxic gas sensor 703 is responsible for real-time detection of the presence and content of toxic gas inside the housing. The data collected by both are synchronously transmitted to controller 5, providing core monitoring basis for controller 5 to determine whether to trigger the warning of display component 9, and realizing multi-dimensional safety monitoring of the operating environment of instrument 2.

[0030] In a preferred embodiment, the display component 9 includes a frame 901, a transparent viewing window 902 mounted on the inner wall of the frame 901, and warning lights 903 mounted on both ends of the outer wall of one side of the frame 901.

[0031] It should be noted that the transparent observation window 902 is made of transparent material, allowing personnel to directly observe the appearance of the instrument 2 inside the protective housing (such as whether it is damaged or whether the connection is loose) without opening the door panel 6.

[0032] The warning light 903 is electrically connected to the controller 5. When the monitoring data received by the controller 5 (from the temperature sensor 702 and the toxic gas sensor 703) exceeds the preset safety value, the controller 5 controls the warning light 903 to light up (or flash) to remind personnel of the abnormal environment inside the housing with a visual light signal, which requires timely handling, thus achieving a combination of "passive observation" and "active early warning".

[0033] In a preferred embodiment, the limiting component 14 includes a slider 1401, a spring 1402 mounted on one side of the outer wall of the slider 1401, and an insert plate 1403 mounted on the top of the slider 1401.

[0034] It should be noted that when the door panel 6 is lowered to serve as a maintenance platform, the handle 8 presses down on the insert plate 1403, causing the slider 1401 to slide along the sliding rod 13 to both sides and compress the spring 1402. When the limiting groove 10 is aligned with the insert plate 1403, the spring 1402 resets and pushes the slider 1401 back, causing the insert plate 1403 to engage with the limiting groove 10. The elastic force of the spring 1402 maintains the engagement state between the insert plate 1403 and the limiting groove 10, thereby fixing the handle 8 and keeping the door panel 6 stably horizontal.

[0035] When it is necessary to close the door panel 6, press down on the pressing component 15. The pressing component 15 drives the two sliders 1401 to slide along the sliding rod 13 to both sides. The insert plate 1403 moves out of the limiting groove 10, releasing the fixation of the handle 8. At this time, the door panel 6 can be flipped up to close.

[0036] In a preferred embodiment, the pressing assembly 15 includes connecting rods 1501 rotatably mounted on the outer walls of the two insert plates 1403 and pressing plates 1502 rotatably connected to the tops of the two connecting rods 1501.

[0037] It should be noted here that when the person presses down on the pressing plate 1502, the pressing plate 1502 moves downward, causing the two connecting rods 1501 to rotate around the connection point. The other end of the connecting rod 1501 pushes the slider 1401 to both sides, causing the slider 1401 to slide along the sliding rod 13 and compress the spring 1402, ultimately causing the insert plate 1403 to disengage from the limiting groove 10.

[0038] This structure uses the lever action of the connecting rod 1501 to convert the vertical pressing force into the horizontal thrust force. Only a small pressing force is needed to drive the two limit components 14 to move synchronously, so as to quickly release the fixed state of the door panel 6 and improve the convenience of operation.

[0039] In a preferred embodiment, the outer walls of the two insert plates 1403 on opposite sides are both inclined structures.

[0040] It should be noted here that the outer wall of the two insert plates 1403 on opposite sides is a sloping structure. When the door panel 6 is flipped down, the handle 8 first contacts the sloping surface of the insert plate 1403.

[0041] As the door panel 6 continues to rotate downwards, the handle 8 exerts downward pressure on the inclined plane. This pressure is decomposed into a horizontal component along the inclined plane, pushing the two insert plates 1403 to move to both sides (causing the slider 1401 to slide and compress the spring 1402).

[0042] When the limiting groove 10 on the handle 8 is aligned with the position of the insert plate 1403, the spring 1402 resets and pushes the insert plate 1403 to automatically engage with the limiting groove 10. The door panel 6 can be fixed without the need for manual adjustment of the position of the insert plate 1403, which greatly improves the efficiency of the maintenance platform setup.

[0043] Working principle:

[0044] The basic protection and installation fixation involves installing the upper housing 3 and the lower housing 4 outside the chemical pipeline 1 to form a closed protective housing, completely enclosing the instrument 2 that needs protection, isolating it from external dust, water vapor, mechanical impact and other interference factors, providing a stable and safe operating environment for the instrument 2, and completing the basic physical protection and installation fixation.

[0045] Environmental monitoring and data transmission are achieved by installing a temperature sensor 702 and a toxic gas sensor 703 (which together form monitoring component 7) on a mounting plate 701 on the inner wall of one side of the upper housing 3. These sensors continuously monitor the temperature and toxic gas content inside the protective housing. The monitored data is transmitted in real time to a controller 5 installed on the outer wall of one side of the upper housing 3, where the controller 5 analyzes and processes the data.

[0046] Warning prompts and status observation: When the controller 5 determines that the received data such as temperature and toxic gas content are higher than the preset safety value, it will trigger the operation of the display component 9 embedded in the outer wall of the door panel 6: the warning light 903 on one side of the frame 901 in the display component 9 will light up or flash, issuing an environmental abnormality warning to the staff; at the same time, the staff can directly observe the appearance status of the instrument 2 inside the protective housing (such as whether it is damaged, whether the connection is loose, etc.) through the transparent observation window 902 inside the frame 901, and can grasp the core information without opening the device.

[0047] For secure unlocking and door panel opening, when the instrument panel 2 needs to be inspected, the operator must wear a magnetic tag (sensor) on protective equipment (such as gloves and a face mask) and bring the sensor close to the sensing area on the surface of the door panel 6 (distance ≤ 5cm). The sensor is wirelessly linked to the magnetic lock cylinder 11 at the top of the door panel 6, sending an "unlock signal" to the magnetic lock cylinder 11. After unlocking, the operator can use the handle 8 on one side of the door panel 6 to flip the door panel 6, which is hinged to the bottom of the mounting opening, downwards.

[0048] After the maintenance platform is set up and the door panel 6 is lowered, the handle 8 is supported on the lower housing 4, keeping the door panel 6 horizontal. At this time, the door panel 6 can be used as a temporary maintenance platform for placing maintenance tools. At the same time, on the sliding rod 13 inside the mounting frame 12 on one side of the lower housing 4, two limiting components 14 (composed of slider 1401, spring 1402, and insert plate 1403) drive the insert plate 1403 to move inward under the elastic force of spring 1402, and lock it into the limiting grooves 10 on both sides of the handle 8, thus fixing the handle 8 and preventing the door panel 6 from shaking during maintenance, ensuring stable maintenance operation.

[0049] After the door panel closing and limit release maintenance is completed, when closing the door panel 6, the worker presses down on the pressing plate 1502 in the pressing assembly 15. The pressing plate 1502 drives the connecting rod 1501, which is rotatably connected at both ends, to move. The connecting rod 1501 pushes the two insert plates 1403 and the bottom slider 1401 to slide along the sliding rod 13 to both sides. The spring 1402 is compressed, and the insert plates 1403 move out of the limit groove 10, releasing the fixation of the handle 8. Subsequently, the worker flips the door panel 6 upward to close the installation port, and the magnetic lock cylinder 11 automatically resets and locks, restoring the device to a closed protection state.

[0050] 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.
