Description

Technical Field

[0001] This utility model relates to the field of hydraulic valves, and in particular to a high-altitude hydrogen accumulation detection device. Background Technology

[0002] During hydrogen production, the horizontal structure of the hydrogen production tanks makes them prone to deformation, potentially leading to hydrogen leaks. These leaked hydrogen tends to accumulate on the roof of the plant. Detecting this accumulated hydrogen presents several challenges, primarily twofold: first, the roof height is typically high, generally over 6 meters, making detection difficult; second, the irregular roof shape, such as an inverted V-shape, and the uneven surface make securing instruments challenging and operationally difficult. Maintaining specialized explosion-proof detectors is also inconvenient. Current technologies involve fixed placement of hydrogen detection and warning devices, which is impractical and dangerous on high roofs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-altitude hydrogen accumulation detection device, which solves the problem of the difficulty in detecting hydrogen leakage from the roof in indoor spaces.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-altitude hydrogen accumulation detection device, comprising an annular outer balloon, wherein an inner balloon is provided inside the outer balloon, and the inner balloon is filled with a gas with a specific gravity less than air. The inner balloon is annular and adapted to fit inside the outer balloon.

[0005] Preferably, the inner balloon is filled with hydrogen or helium.

[0006] A support frame is installed within the annular space of the outer balloon. The support frame is shaped to fit the inner wall of the annular structure, with a hollow center. The diameters at the top and bottom are larger, while the diameter in the middle is smaller, forming a stable "I" or "hourglass" shape. A hydrogen detection device is fixedly installed on this support frame.

[0007] Furthermore, the hydrogen detection device is divided into two parts: a main body and a servo device. The main body is equipped with a semiconductor sensor, and the servo device contains a battery and an alarm device. The servo device is electrically connected to the main body via a wire. The alarm device can be a buzzer or an LED light. The main body is mounted on the top of the support frame, while the servo device is mounted on the bottom of the support frame.

[0008] Furthermore, both the inner and outer balloons are equipped with independent inflation ports for easy inflation and maintenance. Multiple protrusions are provided on the outer wall of the inner balloon, and these protrusions are filled with gas to protect the hydrogen detection device.

[0009] Furthermore, a pull rope is provided at the bottom of the outer balloon, and an iron counterweight is located at the bottom of the pull rope. This counterweight not only helps the device maintain a vertical attitude, but also resists low-altitude wind interference to a certain extent, and its weight allows for precise control of the device's levitation height.

[0010] Furthermore, this invention also includes an auxiliary balloon with a magnet at its top and a pull rope at its bottom. This auxiliary balloon can be released independently, and its magnet can be attracted and connected to the iron counterweight at the bottom of the main balloon, thus achieving the purpose of the hydrogen recovery inspection device.

[0011] This invention provides a high-altitude hydrogen accumulation detection device that can conveniently detect hydrogen accumulation in hydrogen production workshops. It is simple to operate, easy to set up and recover, low in cost, and poses low safety risks. It effectively avoids the risk of localized hydrogen accumulation in hydrogen production workshops, ensuring the production safety of hydrogen production enterprises. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0013] Figure 1 This is a schematic diagram of the structure of this utility model.

[0014] Figure 2 This is a schematic diagram of the structure of this utility model in use.

[0015] In the diagram: outer balloon 1, inner balloon 2, protrusion 3, servo device 4, wire 5, hydrogen detection device 6, support frame 7, outer balloon inflation port 8, inner balloon inflation port 9, pull rope 10, iron counterweight 11, magnet block 12, balloon 13, factory building 14, high-altitude hydrogen detection device 15, high-altitude cumulative hydrogen detection device 100. Detailed Implementation

[0016] Example 1:

[0017] like Figure 1 In a high-altitude hydrogen accumulation detection device, there is an annular outer balloon 1, and an inner balloon 2 is provided inside the outer balloon 1. The inner balloon 2 is filled with a gas with a specific gravity less than that of air.

[0018] A support frame 7 is provided within the annular space of the outer balloon 1, and a hydrogen detection device 6 is fixed on the support frame 7. With this structure, when the hydrogen accumulation detection device 100 rises to a location on the top of the factory building 14 where hydrogen is prone to accumulate, the hydrogen detection device 6 detects the hydrogen concentration. If the concentration exceeds a preset value, an alarm is triggered, reminding operators to ventilate and avoid safety risks. In a preferred embodiment, the hydrogen detection device 6 consists of two parts: a main body and a servo device 4.

[0019] The main body is equipped with a semiconductor sensor, using a metal oxide, such as SnO2, as the sensing material. When hydrogen gas is adsorbed on the surface of the material, it reacts with the adsorbed oxygen ions, changing the material's resistance. The hydrogen concentration is determined by measuring the change in resistance. In this example, the hydrogen detection module preferably uses a commercially available FIGARO TGS2616-C00 miniature hydrogen detection device, with a measurement range of 10-3000 ppm, a response time of less than 10 seconds, and an operating temperature of -10℃ to +50℃. The core of the TGS2616-C00 is a miniature metal oxide semiconductor (MOS) sensing element, packaged in a standard TO-5 metal mesh canister. A battery and warning device are located within the servo unit 4. The battery is a 300mA lithium battery, and the servo unit 4 is electrically connected to the main body via a wire. In a preferred embodiment, the warning device includes a buzzer or an LED light. The entire structure is explosion-proof; the entire high-altitude hydrogen detection device 100 adopts an explosion-proof structure. Due to explosion-proof requirements, the high-altitude hydrogen detection device 100 in this example does not employ signal receiving and transmitting devices to improve explosion-proof performance.

[0020] Preferred solutions include Figure 1 In the diagram, inner balloon 2 is a corresponding ring. Alternatively, inner balloon 2 can be made of multiple independent balloons.

[0021] Preferred solutions include Figure 1 In this device, the outer wall of the inner balloon 2 has multiple protrusions 3, which are filled with gas. This structure allows the protrusions 3 to act as a buffer in the event that the entire high-altitude hydrogen detection device 100 falls due to unforeseen circumstances. Additionally, the protrusions 3 can also be used to secure the inner balloon 2 within the outer balloon 1.

[0022] Preferred solutions include Figure 1 In this design, the support frame 7 is shaped to fit the inner wall of an annular structure, with a hollow center and larger diameters at the top and bottom, and a smaller diameter in the middle. In a preferred embodiment, the main body is located at the top of the support frame 7, and the servo device 4 is located at the bottom. This structure achieves better weight distribution, ensuring that the main body of the hydrogen detection device 6 is always positioned at the top, allowing for better contact with accumulated hydrogen and early prevention of accidents. The support frame 7 is preferably made of aluminum alloy.

[0023] In the preferred embodiment, the inner balloon 2 is filled with hydrogen or helium; in this example, helium is preferred to ensure safety.

[0024] Both the inner balloon 2 and the outer balloon 1 have independent inflation ports.

[0025] When using, check that the power supply is sufficient and all components are securely fixed. Then, first fill the inner balloon 2 with helium through the inner balloon inflation port 9. After filling it, fill the outer balloon with air through the outer balloon inflation port 8. Then, in the factory building 14, in a place where hydrogen is likely to accumulate, raise the high-altitude hydrogen detection device 100 to a position where air is likely to accumulate. Once a hydrogen accumulation alarm is detected, start the explosion-proof ventilation system, stop the machine for inspection, and only restart production after the fault has been eliminated.

[0026] Example 2:

[0027] Based on Example 1, the preferred solution is as follows: Figure 2 In the middle, the outer balloon 1 is also equipped with a pull rope 10, and the bottom of the pull rope 10 is equipped with an iron counterweight 11.

[0028] In a preferred embodiment, a balloon 13 is also provided, with a magnet 12 at its top and a pull rope at its bottom. Preferably, to ensure the magnet 12 always faces upwards, a counterweight is also provided on the balloon 13 to keep the magnet 12 pointing upwards. When the high-altitude hydrogen detection device 100 needs to be retrieved for maintenance, such as inflating the inner balloon 2 or charging the battery, the balloon 13 is released below the high-altitude hydrogen detection device 100, causing the magnet 12 at the top of the balloon 13 to attract the iron counterweight 11. Pulling down the pull rope allows the high-altitude hydrogen detection device 100 to be retrieved for maintenance.

[0029] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
