Description

Technical Field

[0001] This utility model relates to the field of nitrogen generator technology, and in particular to a nitrogen generator fault alarm device. Background Technology

[0002] A nitrogen generator is a device that extracts nitrogen from the air using technologies such as adsorption separation and membrane separation. It is widely used in many industries such as chemical, electronics, food, and pharmaceutical. Its operational stability directly affects the continuity of the production process and product quality. During long-term operation of a nitrogen generator, faults such as insufficient nitrogen pressure, abnormal flow, excessively high adsorption tower temperature, and substandard nitrogen purity are prone to occur. If these faults are not detected and dealt with in time, they may cause serious damage to the equipment or even lead to production safety accidents. Therefore, it is necessary to use a fault alarm device to issue an alarm when a fault occurs, so as to alert the staff to deal with the fault in time.

[0003] Existing fault alarm devices typically lack auxiliary fixing structures for connecting lines. The connecting lines are easily loosened by external forces or vibrations, causing the fault alarm to stop working. Moreover, existing fault alarm devices usually lack shock absorption structures, and the devices are easily affected by long-term external vibrations, which reduces the service life of internal electronic components. Furthermore, existing devices lack auxiliary heat dissipation mechanisms, which can easily lead to excessive heat during operation, resulting in decreased operating performance or even causing the device to malfunction.

[0004] Therefore, a nitrogen generator fault alarm device is proposed. Utility Model Content

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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A nitrogen generator fault alarm device includes an alarm device body 1, a line fixing mechanism 2 is provided at the bottom line interface of the alarm device body 1, shock absorption mechanisms 3 are provided on both sides of the alarm device body 1, and a heat dissipation mechanism 4 is provided at the rear of the alarm device body 1.

[0030] The wiring fixing mechanism 2 includes a fixing plate 21, which is fixedly connected to the wiring interface at the bottom of the alarm device body 1. Multiple L-shaped blocks 22 are fixedly connected to the bottom front side of the fixing plate 21. A knob 23 is provided on the front side of the L-shaped block 22. A threaded rod 24 is fixedly connected to the rear side of the knob 23. The rear side of the threaded rod 24 passes through the L-shaped block 22 and is rotatably connected to a movable clamping block 25 through a bearing seat. A fixed clamping block 26 is provided on the rear side of the movable clamping block 25. The rear side of the fixed clamping block 26 is fixedly connected to the fixing plate 21. A fixing groove 27 is provided on the opposite side of the movable clamping block 25 and the fixed clamping block 26. A locking nut 28 is threadedly connected to the front side of the surface of the threaded rod 24.

[0031] In this embodiment, by setting up an alarm device body 1, a wiring fixing mechanism 2, a shock-absorbing mechanism 3, and a heat dissipation mechanism 4, the wiring fixing mechanism 2 can firmly fix the connecting wires at the bottom wiring interface of the alarm device body 1 during use, effectively preventing the wiring interface from becoming loose due to external pulling or vibration, ensuring the reliability and stability of the wiring connection, and maintaining the continuous and stable fault monitoring and alarm function of the alarm device body 1. The shock-absorbing mechanism 3 can effectively buffer and absorb the vibration energy transmitted to the alarm device body 1 from the outside, reducing the impact of vibration on the internal electronic components and other parts of the alarm device body 1, thereby improving the overall service life. The heat dissipation mechanism 4 can quickly dissipate the heat generated by the alarm device body 1 during operation, providing auxiliary heat dissipation for the alarm device body 1, and preventing the alarm device body 1 from overheating due to heat accumulation, which would cause a decrease in operating performance.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the shock absorption mechanism 3 includes two support plates 31, which are fixedly connected to the bottom of both sides of the alarm device body 1. Each of the two support plates 31 has an L-shaped frame 32 at its bottom. Spring damping shock absorbers 33 are fixedly connected to the front and rear sides of the support plates 31 and the L-shaped frame 32.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the front and rear sides of the bottom of the two L-shaped brackets 32 on opposite sides are fixedly connected to the first mounting plate 34, and the top of the first mounting plate 34 is provided with a first mounting hole 35.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the top and bottom of the rear side of the two L-shaped brackets 32 are fixedly connected to the second mounting plate 36, and the front side of the second mounting plate 36 is provided with a second mounting hole 37.

[0035] In this embodiment, by setting up a support plate 31, an L-shaped frame 32, a spring-damped shock absorber 33, a first mounting plate 34, a first mounting hole 35, a second mounting plate 36, and a second mounting hole 37, the L-shaped frame 32 can be installed and fixed to a horizontal mounting surface using bolts through the first mounting hole 35 of the first mounting plate 34, or it can be installed and fixed to a vertical mounting surface using bolts through the second mounting plate 36 and the second mounting hole 37. After installation, the spring-damped shock absorber 33 between the support plate 31 and the L-shaped frame 32 can effectively buffer and absorb the vibration energy transmitted from the outside to the alarm device body 1, such as the vibration of the nitrogen generator, reducing the impact of vibration on the internal electronic components and other parts of the alarm device body 1, thereby improving the overall service life.

[0036] Specifically, such as Figure 1 , Figure 3 , Figure 6 As shown, the heat dissipation mechanism 4 includes a heat dissipation fan 41, which is fixedly connected to the right side of the top of the alarm device body 1. The rear air outlet of the heat dissipation fan 41 is connected to a connecting cover 42, and the rear side of the connecting cover 42 is connected to a connecting pipe 43. The other end of the connecting pipe 43 is connected to a heat dissipation pipe 44, which is distributed in a snake shape on the rear side of the alarm device body 1.

[0037] Specifically, such as Figure 3 , Figure 6 As shown, multiple heat dissipation fins 45 are fixedly connected to the surface of the heat dissipation pipe 44, and the side of the heat dissipation fins 45 closest to the alarm device body 1 is in contact with the alarm device body 1.

[0038] In this embodiment: by setting up a cooling fan 41, a connecting cover 42, a connecting pipe 43, a heat dissipation pipe 44, and heat dissipation fins 45, the cooling fan 41 can be activated when the alarm device body 1 is running, so that the cooling fan 41 continuously draws in cooling airflow, which is then gathered by the connecting cover 42 and introduced into the serpentine heat dissipation pipe 44 through the connecting pipe 43. The multiple heat dissipation fins 45 on the surface of the heat dissipation pipe 44 are in close contact with the alarm device body 1. By the flow of cooling airflow in the heat dissipation pipe 44 and the heat dissipation fins 45 increasing the heat dissipation area, the heat generated by the operation of the alarm device body 1 can be quickly dissipated, providing auxiliary heat dissipation for the alarm device body 1 and preventing the alarm device body 1 from overheating due to heat accumulation inside, which would cause a decrease in operating performance.

[0039] Specifically, such as Figure 4 As shown, the front side of the L-shaped block 22 has a threaded hole 5 that is used to cooperate with the threaded rod 24, and the surface of the threaded rod 24 is connected to the inner wall of the threaded hole 5 by threads.

[0040] Specifically, such as Figure 2 , Figure 4 As shown, both the movable clamping block 25 and the fixed clamping block 26 have arc-shaped elastic pads 6 fixedly connected in their fixing grooves 27. The arc-shaped elastic pads 6 are made of rubber.

[0041] In this embodiment: by setting the threaded hole 5, the threaded rod 24 can be moved back and forth by the thread and the threaded rod 24 can be locked by the thread. By setting the arc-shaped elastic pad 6, the clamping stability can be enhanced and the circuit wear can be avoided.

[0042] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a limiting rod 7 is fixedly connected to the right side of the front of the movable clamping block 25, and the front side of the limiting rod 7 extends through to the front side of the L-shaped block 22.

[0043] Specifically, such as Figure 4 As shown, a sliding hole 8 is provided on the right side of the front side of the L-shaped block 22 to cooperate with the limiting rod 7, and the surface of the limiting rod 7 is slidably connected to the inner wall of the sliding hole 8.

[0044] In this embodiment: by setting the limiting rod 7, the movable clamping block 25 can be guided and limited to ensure that the movable clamping block 25 moves smoothly. By setting the sliding hole 8, the limiting rod 7 can pass through the L-shaped block 22 to slide back and forth.

[0045] Working Principle: In use, the alarm device body 1 serves as the core control alarm unit of the nitrogen generator. The L-shaped frame 32 can be installed and fixed to the horizontal mounting surface using bolts through the first mounting hole 35 of the first mounting plate 34, or it can be installed and fixed to the vertical mounting surface using bolts through the second mounting plate 36 and the second mounting hole 37. After installation, the spring damping shock absorber 33 between the support plate 31 and the L-shaped frame 32 can effectively buffer and absorb the vibration energy transmitted to the alarm device body 1 from the outside, such as the operating vibration of the nitrogen generator, reducing the impact of vibration on the system. The internal electronic components of the alarm device body 1 are affected, thus improving the overall service life. After connecting each connecting line to the line interface at the bottom of the alarm device body 1, the connecting line is placed in the fixed wire groove 27 between the movable clamp 25 and the fixed clamp 26. Then, the knob 23 on the front side of the L-shaped block 22 is rotated to drive the threaded rod 24 to rotate and move backward through the threaded hole 5. The threaded rod 24 will drive the movable clamp 25 to move synchronously, so that the movable clamp 25 and the fixed clamp 26 form a bidirectional clamping of the line. The rubber arc-shaped elastic pad 6 can... Enhancing clamping stability and preventing circuit wear, the movable clamping block 25 moves, causing the limit rod 7 to slide along the sliding hole 8, ensuring that the movable clamping block 25 moves without deviation. Finally, tightening the locking nut 28 on the surface of the threaded rod 24 ensures that the locking nut 28 and the L-shaped block 22 are tightly fitted to lock the threaded rod 24, maintaining the stability of the clamping state. This effectively prevents the circuit interface from loosening due to external pulling or vibration, ensuring the reliability and stability of the circuit connection and maintaining the continuous and stable fault monitoring and alarm function of the alarm device body 1. When the main body 1 is running, the cooling fan 41 can be started, so that the cooling fan 41 continuously draws in cooling airflow, which is then gathered by the connecting cover 42 and introduced into the serpentine heat dissipation pipe 44 through the connecting pipe 43. Multiple heat dissipation fins 45 on the surface of the heat dissipation pipe 44 are in close contact with the alarm device main body 1. The flow of cooling airflow in the heat dissipation pipe 44, combined with the heat dissipation fins 45 to increase the heat dissipation area, can quickly dissipate the heat generated by the operation of the alarm device main body 1, and provide auxiliary heat dissipation for the alarm device main body 1, so as to avoid the alarm device main body 1 from overheating due to heat accumulation inside the alarm device main body 1, which would cause the operating performance to decline.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
