Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical safety inspection technology, and in particular to a safety inspection device for chemical storage tanks. Background Technology
[0002] Safety inspection equipment for chemical storage tanks is a key tool for ensuring the safe operation of these tanks, encompassing multiple inspection dimensions. This includes level gauges for real-time monitoring of liquid levels, pressure sensors for monitoring pressure changes within the tank, and gas detectors for quickly identifying leaked flammable, explosive, or toxic gases. Furthermore, corrosion detectors assess the degree of tank corrosion, infrared thermal imagers detect abnormal temperatures, and ultrasonic flaw detectors identify structural defects. These devices, through non-invasive or contact inspections, provide timely warnings of risks, ensuring the safe storage and operation of the tanks.
[0003] Portable gas detectors play a crucial role in safety monitoring of chemical storage tanks. They detect gas by utilizing a sensor that reacts specifically with the target gas. The core component is the gas sensor. When the gas to be tested enters the detection chamber, it interacts chemically and physically with the sensor's surface or internal materials, such as through catalytic combustion, electrochemical oxidation-reduction, and infrared absorption. These reactions trigger changes in the sensor's electrical signal. This signal is amplified and processed by the circuitry, converting it into a gas concentration value, which is displayed in real-time on the screen. Simultaneously, when the concentration exceeds the limit, the equipment triggers an audible and visual alarm, enabling rapid and real-time monitoring of gas leaks or concentrations.
[0004] In existing technologies, some portable gas detectors are susceptible to damage from external moisture, dust, and other contaminants due to insufficient sealing, leading to distorted detection results. When there is an actual leak of toxic, flammable, or explosive gas, the device may display a concentration within acceptable limits, causing operators to misjudge the situation, miss emergency evacuation or response opportunities, and increase the risk of poisoning, explosions, and other safety accidents. Conversely, if the device falsely displays a concentration exceeding the limit, it may trigger unnecessary panic, production stoppages, or emergency responses, resulting in wasted human and material resources and production losses. It may also reduce the reliability of the equipment. Therefore, a chemical storage tank safety detection device is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a chemical storage tank safety testing device, including a base 1. The base 1 serves as the basic frame of the device, providing a stable assembly benchmark for each component through its own structure, thus ensuring the overall stability of the device. Two sealing mechanisms 2 are installed inside the base 1. These sealing mechanisms 2 are core components for achieving the device's sealing performance, enhancing the airtightness between the base 1 and the top cover 3, and preventing the intrusion of external moisture, dust, and other impurities.
[0035] A top cover 3 is installed at the top of the base 1. The top cover 3, together with the base 1, forms the upper closed structure of the equipment. Working in conjunction with the sealing mechanism 2 and the sealing ring 298, it protects the internal detection components of the equipment from external interference. Two protective mechanisms 4 are installed on both the left and right sides of the base 1. These mechanisms protect the equipment from external collisions and impacts, reducing damage to the internal components and extending the equipment's service life. A protective shell 5 is fixedly connected to the opposite side of the two protective mechanisms 4, preventing damage to the equipment due to collisions during transport.
[0036] The sealing mechanism 2 includes a pull rod 21, the outer side of which is slidably connected to the inside of the base 1. The pull rod 21 is a manual control component for the sealing operation, and the sealing structure is linked by pulling it with external force. A spring 22 is fixedly connected to the outer side of the pull rod 21. The spring 22 stores and releases elastic force by utilizing elastic deformation to ensure that the sealing mechanism 2 maintains a preset tight state when not in operation. A connecting rod 23 is fixedly connected to the rear side of the pull rod 21. The connecting rod 23 plays a role in force transmission, converting the linear motion of the pull rod 21 into driving the slider 26, so that the action of a single pull rod 21 can act synchronously on two sliders 26.
[0037] Two mounting platforms 24 are slidably connected to the outer side of the connecting rod 23. The mounting platforms 24 provide installation space and support for the internal components, and integrate the transmission and actuation components of the sealing mechanism 2, so that the components cooperate in an orderly manner inside. A slide rail 25 is fixedly connected inside the mounting platform 24. The slide rail 25 provides a guide track for the sliding of the slider 26, limits the movement path of the slider 26, and ensures that the slider 26 slides stably in a predetermined direction. The slider 26 is slidably connected to the inner side of the slide rail 25. The slider 26 moves with the guide of the slide rail 25. Through its own sliding, it synchronously drives the clamping rod 27 and the connecting column 28 to move. It is a key transmission component for the linkage of the sealing mechanism 2.
[0038] A clamping rod 27 is fixedly connected to the top of the slider 26, moving with the slider 26. By cooperating with the subsequent clamping block 295, it clamps the mounting block 297 from one side, contributing to the sealing and reinforcement of the connection between the top cover 3 and the base 1. A connecting post 28 is fixedly connected to the bottom of the slider 26. The outer side of the connecting post 28 cooperates with the V-shaped rod 291 of the fixing component 29. By sliding within the groove 293, it pushes the V-shaped rod 291 to rotate, triggering the linkage sealing action of the fixing component 29. The fixing component 29 is installed on the outer side of the connecting post 28. Through multi-component linkage, the fixing component 29 clamps and fixes the mounting block 297 from multiple angles, strengthening the sealing connection between the base 1 and the top cover 3.
[0039] The fixing component 29 includes two V-shaped rods 291. The inner sides of the two V-shaped rods 291 are slidably connected to the outer sides of the connecting post 28. The V-shaped rods 291 transmit the movement of the connecting post 28 to the sliding post 292, so that their lateral movement is converted into the tilting movement of the sliding post 292. The other ends of the two V-shaped rods 291 are slidably connected to two sliding posts 292. When the V-shaped rods 291 rotate, the sliding posts 292 slide along the grooves 293 and the recesses 296, guiding the movement of the V-shaped rods 291 and ensuring smooth transmission of the fixing component 29. The interior of each V-shaped rod 291 has two grooves 293, which are adapted to the sliding of the sliding posts 292 and the connecting post 28, providing space and guidance for the rotation of the V-shaped rods 291 and the sliding of the connecting post 28.
[0040] Two connecting rods 294 are fixedly connected to the outer sides of each of the two sliding columns 292. The connecting rods 294 transmit the movement of the sliding column 292 to the clamping block 295, converting the movement of the sliding column 292 into the clamping action of the clamping block 295. This is the intermediate link in the force transmission of the fixing component 29. Two clamping blocks 295 are fixedly connected inside each of the two connecting rods 294. The clamping blocks 295 cooperate with the clamping rod 27 to clamp the mounting block 297 from the other side, forming a clamping structure for the sealing part together with the clamping rod 27 to achieve a sealing effect. Two grooves 296 are formed inside the mounting platform 24. The grooves 296 provide sliding space for the bottom end of the sliding column 292, limiting and guiding the movement of the sliding column 292, and ensuring the stability of the sliding column 292 position during the transmission of the fixing component 29.
[0041] Mounting blocks 297 are installed on the inner sides of the two grooves 296. The mounting blocks 297 are the clamping objects of clamping rod 1 27 and clamping block 295. By being clamped and fixed, the connection between the top cover 3 and the base 1 is locked. A sealing ring 298 is fixedly connected to the top of the base 1. The sealing ring 298 fills the gap between the base 1 and the top cover 3 by its own elastic deformation. It is the direct component for the physical sealing of the equipment.
[0042] Reference Figure 1 , Figure 4 , Figure 5 The protective mechanism 4 includes two sliding rods 41. The outer sides of the two sliding rods 41 are slidably connected to the inside of the base 1. The sliding rods 41 provide a mounting and sliding carrier for components such as the round rod 42 and the irregular block 43. They can slide along the base 1 to install the protective shell 5 on the outside of the base 1. The round rod 42 is slidably connected inside the sliding rod 41. The rear side of the round rod 42 is connected to the irregular block 43, and the front side contacts the linkage rod 451 of the release component 45, which plays a role in force transmission and triggering, and can convert external impact into a thrust on the irregular block 43.
[0043] A shaped block 43 is fixedly connected to the rear side of the round rod 42. The inner side of the shaped block 43 cooperates with the locking block 44. By sliding itself, the locking block 44 is pushed to move, which is the intermediate transmission component connecting the round rod 42 and the locking block 44, and can change the direction of force transmission. Two locking blocks 44 are slidably connected to the inner side of the shaped block 43. Driven by the shaped block 43, they can move and lock into the corresponding structure of the base 1 when the base 1 is connected to the protective shell 5 to achieve connection. A release component 45 is installed inside the base 1. The release component 45 can separate the base 1 from the protective shell 5 through the coordinated action of the internal components.
[0044] The release assembly 45 includes a linkage rod 451, the outer side of which is slidably connected to the inside of the base 1. The linkage rod 451 can transmit the force it receives to the round rod 42, causing the round rod 42 to move forward. The movement of the round rod 42 drives the irregular block 43 to move forward, thereby causing the locking block 44 to retract inward. A push rod 452 is fixedly connected to the bottom end of the linkage rod 451. The push rod 452 can transmit its own force to the linkage rod 451, causing the linkage rod 451 to drive the round rod 42 to move. A push block 453 is fixedly connected to the bottom end of the push rod 452. The push block 453 is a directly contactable actuator. Pushing the push block 453 drives a series of subsequent components to move. A spring plate 454 is fixedly connected inside the base 1. Under normal conditions, the spring plate 454 maintains the position of the push rod 452 through elasticity. When pushed, it deforms and stores energy. After being released, it resets and drives the push rod 452 back to its initial state, providing a reset force for the release assembly 45.
[0045] Reference Figure 1 , Figure 3 , Figure 5 The other end of the spring 22 is fixedly connected to the inside of the base 1. The spring 22 can provide a restoring force to the moving parts it is connected to through its own elastic deformation. The top ends of the two V-shaped rods 291 are rotatably connected to the inside of the mounting platform 24, so that the V-shaped rods 291 can convert the movement of the connecting post 28 into the movement of the sliding post 292. The top end of the sealing ring 298 contacts the bottom end of the top cover 3. The outer side of the sliding post 292 is slidably connected to the inside of the rear sliding groove 293. The outer side of the connecting post 28 is slidably connected to the inside of the rear sliding groove 293, and the bottom end of the sliding post 292 is slidably connected to the inside of the groove 296. The groove 296 can provide guidance for the sliding post 292, so that it moves along a preset direction.
[0046] The outer side of the locking block 44 is slidably connected to the inside of the sliding rod 41. The extension and retraction of the locking block 44 enables the connection between the base 1 and the protective shell 5. The outer side of the irregularly shaped block 43 is slidably connected to the inside of the sliding rod 41, which provides space for its movement. The rear side of the linkage rod 451 is mounted on the front side of the round rod 42. The linkage rod 451 and the round rod 42 can be embedded together. Applying a large pulling force to both the linkage rod 451 and the round rod 42 will separate them. The front side of the push rod 452 contacts the rear side of the spring piece 454, which ensures that the push rod 452 remains stable in a fixed position under normal conditions. The outer side of the push rod 452 is slidably connected to the inside of the base 1.
[0047] Working principle: Pulling the lever 21 causes it to move. This movement causes the spring 22 to elastically deform, storing elastic potential energy. Simultaneously, the movement of the lever 21 drives the connecting rod 23, which in turn causes the slider 26 to slide inside the slide rail 25, moving the clamping rod 27 outwards. The movement of the slider 26 then drives the connecting post 28, causing the two V-shaped rods 291 slidingly connected to the outside of the connecting post 28 to rotate. The movement of the V-shaped rods 291 is transmitted to the connecting rod 294 via the sliding post 292, causing the connecting rod 294 to move within the groove 296. Under tension, the connecting rod 294 moves along a preset direction via the sliding column 292 and the clamping block 295, causing the clamping block 295 to move outward. This works in conjunction with the clamping rod 27 to release the mounting block 297. If the pull rod 21 is released, the spring 22 releases its stored elastic potential energy, fixing the mounting block 297 to the clamping rod 27 and the clamping block 295. This, in turn, presses the sealing ring 298 to seal the device, reducing interference from external environmental factors on the detection results and ensuring the accuracy and reliability of gas detection data. This allows the instrument to play a more stable role in industrial inspections, environmental monitoring, and other scenarios.
[0048] Pushing the protective shell 5 forward causes the sliding rod 41 to move, which in turn causes the round rod 42 to move. When the round rod 42 contacts the base 1, it moves backward and moves the irregular block 43 backward. The round rod 42 and the irregular block 43 work together to push the locking block 44 outward, thus fixing the protective shell 5. To remove the protective shell 5, push the push block 453. The push block 453 causes the push rod 452 to move forward, which in turn causes the linkage rod 451 to move forward, pulling the round rod 42 forward. The movement of the round rod 42 causes the locking block 44 to retract inward, thus releasing the protective shell 5. Releasing the push block 453 allows the spring piece 454 to return the push block 453 to its original position. Installing a conveniently detachable protective cover on the device provides physical protection and reduces wear or deformation of the shell caused by bumps and friction during daily carrying and use, extending the integrity of the device's appearance. The convenient disassembly design allows users to quickly install and remove the device without the need for tools.
