Description

Technical Field

[0001] This utility model relates to the field of air pressure monitoring technology, and in particular to an air pressure monitoring alarm device. Background Technology

[0002] Ultra-low temperature micro-volume environmentally friendly cooling systems are commonly used in machine tool processing, food and pharmaceutical cold chain logistics, and scientific research. For example, ultra-low temperature atomization cooling systems for machine tools require mixing low-temperature airflow with a small amount of lubricating oil and spraying it into the processing area, requiring the air source pressure to be stable between 0.4-0.8 MPa. In food and pharmaceutical cold chain logistics, ultra-low temperature refrigeration systems require precise control of temperature and pressure to ensure the quality of goods.

[0003] In cryogenic micro-volume environmentally friendly cooling systems, both excessively high and low air pressure can affect cooling performance. If the air pressure is too low, the cooling medium cannot be effectively delivered to the designated location, resulting in delayed cooling and impacting machining accuracy or the preservation of materials. For example, in cryogenic MQL micro-volume lubrication cooling technology, insufficient air pressure will lead to poor atomization of the lubricating oil, failing to effectively reduce cutting temperature. Conversely, excessively high air pressure may cause problems such as pipe rupture, seal damage, and even safety accidents.

[0004] Therefore, air pressure monitoring and alarm equipment has emerged. However, existing air pressure monitoring and alarm equipment is fixed to the ultra-low temperature micro-volume environmentally friendly cooling system with screws. When a fault or damage occurs, it needs to be disassembled and replaced with tools, which is inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a barometric pressure monitoring and alarm device, which aims to solve the problem that existing barometric pressure monitoring and alarm devices require tools for disassembly and replacement after failure or damage, which is inconvenient.

[0006] To achieve the above objectives, this utility model provides a barometric pressure monitoring and alarm device, comprising a monitoring and alarm device body and an installation assembly. The installation assembly includes a connecting plate, a snap-fit ​​base, a clamping strip, and a disassembly screw. The connecting plate is mounted on the surface of an ultra-low temperature micro-volume environmentally friendly cooling system. The clamping strip is slidably connected to the connecting plate and located on one side of the clamping strip. The snap-fit ​​base is fixedly connected to the monitoring and alarm device body and snaps into the connecting plate, and is located on one side of the connecting plate. The snap-fit ​​base has grooves located on both sides of the snap-fit ​​base. The disassembly screw is rotatably connected to the connecting plate and passes through the connecting plate and the clamping strip.

[0007] The mounting assembly also includes a suction cup, which is fixedly connected to the connecting plate and located inside the connecting plate.

[0008] The mounting assembly further includes a guide slide rod, which is fixedly connected to the connecting plate and slidably connected to the clamping strip, and passes through the clamping strip.

[0009] The clamping strip includes a clamping strip body and a rubber pad. The clamping strip body is slidably connected to the connecting disc and is located inside the connecting disc. The rubber pad is fixedly connected to the clamping strip body and is located on one side of the clamping strip body.

[0010] The clamping strip includes a clamping strip body and a rubber pad. The clamping strip body is slidably connected to the connecting disc and is located inside the connecting disc. The rubber pad is fixedly connected to the clamping strip body and is located on one side of the clamping strip body.

[0011] This utility model discloses a gas pressure monitoring and alarm device. The device body monitors the gas pressure of an ultra-low temperature micro-volume environmentally friendly cooling system in real time based on sensor technology (existing technology). When the gas pressure is abnormal, an alarm is triggered to notify the administrator for handling. Specifically, the sensor collects the current gas pressure value of the cooling system's gas pipeline in real time. The processing layer performs temperature compensation and linearization correction on the original signal to convert it into accurate gas pressure data (the unit is usually MPa or kPa). The real-time data is compared with preset safety thresholds (upper limit, lower limit, and warning value). If it is within the normal range, monitoring continues. If it exceeds the range, an alarm is triggered. The alarm layer activates audible and visual alarms, remote alarms, etc., and can perform emergency handling according to the set linkage system (such as shutting off the gas source valve) until the gas pressure returns to normal, and then automatically or manually deactivates the alarm. The installation assembly is used to quickly install the monitoring and alarm device body onto the surface of the ultra-low temperature micro-volume environmentally friendly cooling system. When the monitoring and alarm device body is damaged and needs replacement, the maintenance personnel use their hands to rotate the disassembly screw, driving the clamping strips on both sides of the locking base to move, causing the clamping strips to slide away from the locking base within the connecting plate, thereby releasing the clamp on the connecting plate. At this time, the monitoring and alarm device body is then pulled away from the connecting plate, pulling the locking base out of the connecting plate, thus achieving the disassembly of the damaged monitoring and alarm device body and replacement with a new monitoring and alarm device body. Insert the snap-fit ​​base plate at the bottom of the monitoring and alarm device body into the connecting plate, and rotate the disassembly screw in the opposite direction to drive the clamping strip to return to the snap-fit ​​base plate, thereby clamping and fixing the snap-fit ​​base plate. At this time, the clamping strip is inserted into the groove of the snap-fit ​​base plate, realizing the installation of the monitoring and alarm device body and completing the replacement of the monitoring and alarm device body. Replacing the monitoring and alarm device body can be achieved simply by rotating the disassembly screw, without the need for tools to remove multiple screws. Disassembly and assembly are quick and convenient, thus solving the problem that existing air pressure monitoring and alarm devices require tools to disassemble and replace after failure or damage, which is inconvenient.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1 to 4 This utility model provides a barometric pressure monitoring and alarm device, including a monitoring and alarm device body 1 and an installation component 2. The installation component 2 includes a connecting plate 21, a snap-fit ​​base 22, a clamping strip 23, and a disassembly screw 24. The connecting plate 21 is mounted on the surface of an ultra-low temperature micro-volume environmentally friendly cooling system. The clamping strip 23 is slidably connected to the connecting plate 21 and is located on one side of the clamping strip 23. The snap-fit ​​base 22 is fixedly connected to the monitoring and alarm device body 1 and snaps into the connecting plate 21, and is located on one side of the connecting plate 21. The snap-fit ​​base 22 has a groove 27 located on both sides of the snap-fit ​​base 22. The disassembly screw 24 is rotatably connected to the connecting plate 21 and passes through the connecting plate 21 and the clamping strip 23.

[0020] In this embodiment, the monitoring and alarm device 1 monitors the air pressure of the ultra-low temperature micro-volume environmentally friendly cooling system in real time based on sensor technology (existing technology), and triggers an alarm to notify the administrator when the air pressure is abnormal. Specifically, the sensor collects the current air pressure value of the air pipeline of the cooling system in real time. The processing layer performs temperature compensation and linearization correction on the original signal and converts it into accurate air pressure data (the unit is usually MPa or kPa). The real-time data is compared with the preset safety thresholds (upper limit, lower limit and warning value). If it is within the normal range, it continues to monitor. If it exceeds the range, it triggers an alarm. The alarm layer activates audible and visual alarms, remote alarms, etc., and can perform emergency handling according to the set linkage system (such as shutting off the air source valve) until the air pressure returns to normal, and then automatically or manually cancels the alarm. The installation component 2 is used to quickly install the monitoring and alarm device body 1 onto the surface of the ultra-low temperature micro-volume environmentally friendly cooling system. When the monitoring and alarm device body 1 is damaged and needs replacement, the maintenance personnel use their hands to rotate the disassembly screw 24, driving the clamping strips 23 on both sides of the locking base 22 to move, causing the clamping strips 23 to slide away from the locking base 22 within the connecting plate 21, thereby removing the clamping on the connecting plate 21. At this time, the monitoring and alarm device body 1 is pulled away from the connecting plate 21, and the locking base 22 is pulled out of the connecting plate 21, thus achieving the disassembly of the damaged monitoring and alarm device body 1 and the replacement with a new monitoring and alarm device body 1. Insert the snap-fit ​​base 22 at the bottom of the monitoring and alarm device body 1 into the connecting plate 21, and rotate the disassembly screw 24 in the opposite direction to drive the clamping strip 23 to return to the snap-fit ​​base 22, thereby clamping and fixing the snap-fit ​​base 22. At this time, the clamping strip 23 is inserted into the groove 27 of the snap-fit ​​base 22, realizing the installation of the monitoring and alarm device body 1 and completing the replacement of the monitoring and alarm device body 1. Replacing the monitoring and alarm device body 1 can be achieved simply by rotating the disassembly screw 24, without the need to remove multiple screws with tools. The disassembly and assembly are quick and convenient, thus solving the problem that existing air pressure monitoring and alarm devices require tools to disassemble and replace after failure or damage, which is inconvenient.

[0021] Furthermore, the mounting component 2 also includes a suction cup 25, which is fixedly connected to the connecting plate 21 and located inside the connecting plate 21.

[0022] In this embodiment, the suction cup 25 is used to adsorb and fix the bottom of the snap-fit ​​base 22 onto the connecting plate 21, which further enhances the stability of the installation of the monitoring and alarm device body 1. The connecting plate 21 is pre-installed on the surface of the ultra-low temperature micro-quantity environmentally friendly cooling system by bolts.

[0023] Furthermore, the mounting assembly 2 also includes a guide slide rod 26, which is fixedly connected to the connecting disc 21 and slidably connected to the clamping strip 23, and passes through the clamping strip 23.

[0024] In this embodiment, the guide slide bar 26 is provided to assist the clamping bar 23 in sliding when the disassembly screw 24 rotates to drive the clamping bar 23.

[0025] Furthermore, the clamping strip 23 includes a clamping strip body 231 and a rubber pad 232. The clamping strip body 231 is slidably connected to the connecting disc 21 and is located inside the connecting disc 21. The rubber pad 232 is fixedly connected to the clamping strip body 231 and is located on one side of the clamping strip body 231.

[0026] In this embodiment, the clamping strip body 231 is inserted into the groove 27 to clamp and fix the snap-fit ​​base 22. The rubber pad 232 enhances the friction between the clamping strip body 231 and the snap-fit ​​base 22, further strengthening the fixing effect of the clamping strip body 231 on the snap-fit ​​base 22.

[0027] Furthermore, the disassembly screw 24 includes a bidirectional screw 241 and a rotating head 242. The bidirectional screw 241 is rotatably connected to the connecting disc 21 and threadedly connected to the clamping bar body 231, and passes through the connecting disc 21. The rotating head 242 is fixedly connected to the bidirectional screw 241 and is located on one side of the bidirectional screw 241.

[0028] In this embodiment, the rotation of the bidirectional screw 241, under the action of the thread, drives the two clamping bar bodies 231 to move in opposite directions, thereby simultaneously controlling the movement of the two clamping bar bodies 231, realizing the action of the clamping bar bodies 231 moving closer to or away from the locking chassis 22. The setting of the rotating head 242 makes it convenient for maintenance personnel to rotate the bidirectional screw 241, improving practicality.

[0029] The above-disclosed embodiments are merely preferred embodiments of a barometric pressure monitoring and alarm device of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application still fall within the scope of this application.
