A fixed frame component is movably connected and installed at the lower rear end of the leak detector assembly, and an adjusting support is connected and installed on the side of the fixed frame component away from the leak detector assembly. The adjusting bracket is connected and installed at the end of the adjusting support away from the fixed frame component.

The second damping joint is connected and installed at the lower end of the main frame, and a fixing seat is connected and installed at the end of the second damping joint away from the main frame.

[0006] Furthermore, the leak detector assembly includes a hydrogen detector body, a control panel, an air inlet, an alarm, and a connector. The control panel is provided on the upper front surface of the hydrogen detector body, and the air inlet is provided on the lower front surface of the hydrogen detector body. An alarm is connected and installed on the upper side of the hydrogen detector body, and a connector is provided on the lower rear surface of the hydrogen detector body.

[0007] Furthermore, the air inlet is arranged in four equidistant arrays, the connecting seat and the main body of the hydrogen detector are integrated into one structure, and the fixing frame and the connecting seat are connected to each other in an embedded splicing structure. Moreover, the four diagonal corners on the side of the fixing frame and the connecting seat that are connected to each other are provided with holes for bolt installation.

[0008] Furthermore, the adjusting support includes a docking frame, a docking seat, a damping rotary shaft, and a combination seat. The docking frame is connected to the docking seat on the side away from the fixed frame component, and the docking seat is connected to and installed on the side away from the docking frame.

[0009] Furthermore, the docking seat, damping rotary shaft and combination seat are set as an integral structure, and the docking frame and docking seat are movably connected.

[0013] This utility model provides a hydrogen leak detection mechanism and a generator constant cooling water system containing the mechanism, which has the following beneficial effects:

[0014] 1. This utility model, by incorporating an adjustable bracket, wherein the main frame of the adjustable bracket serves as a supporting foundation and is connected to the connecting seat and the fixed seat via a first damping joint and a second damping joint, respectively, not only enhances the flexibility of the entire bracket but also ensures stability and adaptability in different installation environments. The damping characteristics of the first and second damping joints make the adjustment process smooth and controllable, effectively avoiding impacts and vibrations caused by sudden movement or adjustment, thereby protecting the accuracy and lifespan of the leak detector component. Simultaneously, the mobility of the first and second damping joints themselves provides the entire device with a wider adjustment range and finer adjustment precision. In use, operators can adjust the angle and position of the first and second damping joints according to specific installation requirements and the operating environment to achieve vertical folding and adjustment of the leak detector component in three-dimensional space, effectively improving the flexibility and adaptability of the equipment and avoiding unnecessary structural interference from external equipment that could affect the operation of the leak detector component.

[0015] 2. This utility model, through the structural design of the fixed frame and the adjustable support, utilizes the structural mobility of the damping rotary shaft to achieve axial rotation of the leak detector assembly in the horizontal direction. The docking frame in the adjustable support is movably connected to the fixed frame, and the integrated structure formed by the docking seat, the damping rotary shaft, and the combined seat allows the docking frame to rotate smoothly relative to the fixed frame. The design of the damping rotary shaft not only provides the necessary damping effect, ensuring the smoothness and controllability of the rotation process, but also effectively prevents accidental rotation caused by external forces, thereby enhancing the stability and safety of the entire device. Operators can adjust the angle of the adjustable support to achieve flexible rotation of the leak detector assembly in the horizontal direction according to actual needs, adapting to different working environments and installation conditions.

[0016] 3. This utility model, due to the modular structure of the leak detector components, fixed frame parts, adjusting supports, and adjusting brackets, allows for easy disassembly and reassembly of each component. This not only improves the maintainability of the equipment but also allows users to flexibly configure the equipment according to actual needs, reducing operating costs. Simultaneously, the modular design facilitates equipment upgrades and modifications, enabling the equipment to keep pace with technological developments and maintain its advanced nature and competitiveness. Furthermore, through modular design, this utility model effectively integrates the leak detection mechanism with the generator's constant cooling water system, optimizing the gas flow through the four sets of air inlets on the main body of the hydrogen detector. The efficient air intake ensures that the hydrogen detector can comprehensively and quickly detect any potential hydrogen leaks in the surrounding environment. The integrated structure between the connector and the detector enhances overall stability and durability, preventing decreased detection accuracy or equipment damage due to loose connections during long-term use. Furthermore, the embedded splicing structure between the fixed frame components and the connector simplifies installation and improves connection reliability and sealing. When the hydrogen concentration exceeds the preset safety threshold, the alarm will automatically activate, promptly issuing an alarm signal to remind operators to take appropriate measures to prevent hydrogen leaks from causing safety accidents.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4 As shown, a hydrogen leak detection mechanism and a generator constant cooling water system containing the mechanism include a leak detector assembly 1 and an adjusting bracket 4. A fixed frame component 2 is movably connected to the lower rear end of the leak detector assembly 1, and an adjusting support 3 is connected to the side of the fixed frame component 2 away from the leak detector assembly 1. The adjusting bracket 4 is connected to the end of the adjusting support 3 away from the fixed frame component 2. The adjusting bracket 4 includes a main frame 401, a first damping joint 402, a connecting seat 403, a second damping joint 404, and a fixing seat 405. The first damping joint 402 is connected to the upper end of the main frame 401, and the first damping joint 402 is located away from the main frame 401. One end is connected to a connecting seat 403, and the lower end of the main frame 401 is connected to a second damping joint 404. The end of the second damping joint 404 away from the main frame 401 is connected to a fixing seat 405. The second damping joint 404 and the fixing seat 405 are detachable. The first damping joint 402 and the connecting seat 403 are also detachable. In use, the operator can adjust the angle and position of the first damping joint 402 and the second damping joint 404 according to the specific installation requirements and the usage environment to realize the vertical folding adjustment of the leak detector assembly 1 in three-dimensional space.

[0024] like Figures 1 to 4 As shown, the leak detector assembly 1 includes a hydrogen detector body 101, a control panel 102, an air inlet 103, an alarm 104, and a connector 105. The control panel 102 is located on the upper front surface of the hydrogen detector body 101, and the air inlet 103 is located on the lower front surface of the hydrogen detector body 101. The alarm 104 is connected and installed on the upper side of the hydrogen detector body 101, and the connector 105 is located on the lower rear surface of the hydrogen detector body 101. Four sets of air inlets 103 are arranged in an equidistant array. The leak detector component 1 and the main body 101 of the hydrogen detector are integrated into one structure, and the fixing frame component 2 and the connecting seat 105 are connected to each other in an embedded splicing structure. Moreover, the four diagonal holes for bolt installation are opened on the side of the fixing frame component 2 and the connecting seat 105 that are connected to each other. Since the leak detector component 1, the fixing frame component 2, the adjusting support 3 and the adjusting bracket 4 adopt a modular structure, the components can be easily disassembled and reassembled. This not only improves the maintainability of the equipment, but also allows users to flexibly configure the equipment according to actual needs.

[0025] like Figures 1 to 4As shown, the adjusting support 3 includes a docking frame 301, a docking seat 302, a damping rotary shaft 303, and a combination seat 304. The docking frame 301 is connected to the docking seat 302 on the side away from the fixed frame component 2, and the damping rotary shaft 303 is connected and installed on the side of the docking seat 302 away from the docking frame 301. The combination seat 304 is provided on the side of the damping rotary shaft 303 away from the docking seat 302. The docking seat 302, the damping rotary shaft 303, and the combination seat 304 are integrated into one structure, and the docking frame 301 and the docking seat 302 are movably connected. Furthermore, four diagonal openings are provided on the opposite sides of the docking frame 301 and the docking seat 302. The hole structure for bolt installation, the docking frame 301 and the fixed frame component 2 are movably connected, and the four diagonal corners of the surface of the connection between the combination seat 304 and the connecting seat 403 are provided with hole structures for bolt installation, and the combination seat 304 and the connecting seat 403 are movably connected. The structural mobility of the damping rotary shaft 303 realizes the axial rotation of the leak detector assembly 1 in the horizontal direction. The docking frame 301 in the adjusting support 3 is movably connected to the fixed frame component 2, and the integrated structure formed by the docking seat 302, the damping rotary shaft 303 and the combination seat 304 allows the docking frame 301 to rotate smoothly relative to the fixed frame component 2.

[0026] By adjusting the structural mobility of the bracket 4, the entire device can be adjusted vertically in two stages of up-and-down folding. At the same time, in conjunction with the structural mobility of the adjustable support 3, axial rotation in the horizontal direction can be achieved. This ensures that the leak detector assembly 1, which is connected and installed using the fixed frame component 2, has good structural adjustability. This achieves stable structural installation while also providing sufficient adjustability for easy operation. On the other hand, it also allows for structural disassembly and use to cope with different installation and usage environments.

[0027] In summary, as Figures 1 to 4 As shown, the hydrogen leak detection mechanism and the generator constant cooling water system containing the mechanism are used as follows: First, the operator fixes the entire device to the corresponding position of the generator constant cooling water system using the fixing seat 405 at one end of the second damping joint 404. Then, the operator can set parameters for the hydrogen detector body 101 through the control panel 102, including the early warning threshold for hydrogen leakage. When the hydrogen concentration in the generator constant cooling water system exceeds the preset safety threshold, the hydrogen detector body 101 will quickly detect the hydrogen leak through the air inlet 103 and immediately trigger the alarm 104 to issue an alarm signal. At this time, the operator can take corresponding measures in time according to the alarm signal, such as shutting down relevant equipment and turning on the ventilation device, to prevent hydrogen leakage from causing safety accidents.

[0028] In addition, the hydrogen leak detection mechanism is highly flexible and adaptable. Operators can adjust the angle and position of the first damping joint 402 and the second damping joint 404 according to the actual installation requirements and usage environment to make the leak detector assembly 1 tilt and adjust in three-dimensional space. At the same time, by utilizing the structural mobility of the damping rotation shaft 303 in the adjusting support 3, operators can also make the leak detector assembly 1 rotate axially in the horizontal direction to adapt to different working environments and installation conditions.

[0029] Since the leak detector assembly 1, fixed frame 2, adjusting support 3, and adjusting bracket 4 adopt a modular structure, when combined installation is required, the operator can first align the embedded splicing structure of the fixed frame 2 with the corresponding position of the connecting seat 105 and fasten the two together with bolts. Then, the docking frame 301 of the adjusting support 3 is movably connected to the fixed frame 2, and is also fixed with bolts through the preset hole structure to ensure the stability and reliability of the connection. Next, the connecting seat 403 of the adjusting bracket 4 is movably connected to the combination seat 304 of the adjusting support 3 and fixed with bolts. At this time, the first damping joint 402 and the second damping joint 404 will be connected to the main frame 401 and the fixed seat 405 respectively, forming a complete support and adjustment structure.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
