Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and more particularly, to an inspection device. Background Art

[0002] Fuel cell technology, as a clean and efficient energy conversion method, has shown great application potential in the transportation field in recent years. Especially in miniaturized and portable applications, air-cooled fuel cells have become the focus of attention due to their unique lightweight design, high power density, and simplified balance-of-plant (BOP) structure. However, as the number of air-cooled fuel cells in practical applications increases, the technical problems they present are becoming increasingly prominent. The most critical one is the lack of a real-time monitoring mechanism for the single-cell voltage monitoring of the stack and abnormal working states (such as stack reversal).

[0003] Currently, most air-cooled fuel cell stacks are not equipped with an effective voltage inspection device. During actual operation, abnormal changes in the single-cell voltage inside the stack or stack reversal phenomena cannot be monitored in a timely manner, which often leads to performance degradation or even permanent damage of the entire fuel cell stack. Voltage inspection plays an irreplaceable role in the performance maintenance, fault diagnosis, and prevention of air-cooled fuel cells, but the application of existing technologies in this field is not yet mature.

[0004] In the field of water-cooled fuel cells, voltage inspection connection methods mainly include pre-connection (welding), reserved hole bonding (adhesive bonding), and special terminal insertion (plug-in) and other means. Although the pre-connection method can achieve stable connection, it requires customization during the bipolar plate production stage, increasing production costs. And once the inspection device is damaged or the connection is poor, the stack must be disassembled to replace the bipolar plate, with complex operation and high costs. The adhesive-bonded inspection connection simplifies the installation process to a certain extent, but the long-term stability of the adhesive is subject to the high-temperature and high-humidity environment of fuel cell operation, and it is prone to connection loosening or corrosion, affecting the accuracy and reliability of inspection. The plug-in inspection connection uses a special terminal design to achieve connection with the stack through precise fitting. However, due to the limitation of the bipolar plate thickness, the contact area is limited and the clamping force is weak. Especially in high-intensity vibration or harsh environments, the connection stability is difficult to guarantee.

[0005] In addition, although the contact-type inspection method can directly contact the side wall of the stack, due to differences in stack assembly processes, thermal expansion and contraction deformation during bipolar plate stacking, and temperature changes in high and low temperature environments, the consistency of the spacing between bipolar plates will be reduced, which in turn affects the connection stability between the inspection terminal and the bipolar plate insert, and is prone to problems such as misalignment, short circuit, and poor contact, reducing the reliability and durability of the inspection system. Summary of the Invention

[0006] The main object of the present invention is to provide an inspection device to solve the problem in the prior art that during the voltage inspection process, due to the change in ambient temperature, the connection stability between the inspection terminal and the component to be detected is affected.

[0007] To achieve the above object, according to one aspect of the present invention, there is provided an inspection device, comprising:

[0008] A clamping structure having a clamping portion for fixing the inspection device to the structure to be installed through the clamping portion;

[0009] A detection structure provided on the clamping structure, the detection structure including a deformable detection unit having an initial state and a detection state. When the detection unit is in the detection state, it is used to detect the component to be detected.

[0014] Wherein, the plurality of detection components together enclose a detection unit having a first space inside. When detecting the component to be detected, the plurality of detection components move towards the direction close to the first space so that the detection unit is in the detection state, and after the detection of the component to be detected is completed, the plurality of detection components move towards the direction away from the first space so that the detection unit is in the initial state.

[0015] Further, the two ends of the detection unit are fixedly connected to the fixing unit; and / or,

[0016] The fixing unit is fixedly connected to the clamping structure.

[0017] Further, the clamping structure includes:

[0019] A second clamping member, one end of the second clamping member is provided with a second connection end, and a second arc-shaped opening is provided on the first connection end;

[0020] Among them, the first clamping member and the second clamping member move relatively closer to each other when detecting the component to be detected, so that the first arc-shaped opening and the second arc-shaped opening jointly form a clamping portion.

[0021] Furthermore, the clamping structure further includes:

[0022] The first hinge hole is opened on the first connection end;

[0023] The second hinge hole is opened on the second connection end;

[0024] The connecting member is rotatably inserted through the first hinge hole and the second hinge hole, so that the first clamping member and the second clamping member are rotatably arranged.

[0025] Furthermore, the clamping structure further includes:

[0026] The first wire harness fixing portion is arranged on the side of the first clamping member away from the first arc-shaped opening. The first wire harness fixing portion extends along the length direction of the first clamping member, and a first accommodating space for accommodating the wire harness is formed in the first wire harness fixing portion.

[0027] Furthermore, the first wire harness fixing portion includes:

[0028] The first mounting plate is arranged on the side of the first clamping member away from the first arc-shaped opening;

[0029] At least two second mounting plates are oppositely arranged on both sides of the first mounting plate in the width direction. The at least two second mounting plates extend along the length direction of the first clamping member, and the width direction of the at least two second mounting plates is perpendicular to the width direction of the first mounting plate;

[0030] At least two third mounting plates are oppositely arranged on the side of the at least two second mounting plates away from the first mounting plate. The width direction of the at least two third mounting plates is arranged parallel to the width direction of the first mounting plate, so as to jointly form the first accommodating space through the first mounting plate, the at least two second mounting plates and the at least two third mounting plates.

[0031] Furthermore, the clamping structure further includes:

[0032] The second wire harness fixing portion is arranged on the side of the second clamping member away from the second arc-shaped opening. The second wire harness fixing portion extends along the length direction of the second clamping member, and a second accommodating space for accommodating the wire harness is formed in the second wire harness fixing portion.

[0033] Furthermore, the second wire harness fixing portion includes:

[0034] The fourth mounting plate is arranged on the side of the second clamping member away from the second arc-shaped opening;

[0035] At least two fifth mounting plates are oppositely arranged on both sides in the width direction of the fourth mounting plate. The at least two fifth mounting plates extend along the length direction of the second clamping member, and the width direction of the at least two fifth mounting plates is perpendicular to the width direction of the fourth mounting plate;

[0036] At least two sixth mounting plates are oppositely arranged on the side of the at least two fifth mounting plates away from the fourth mounting plate. The width direction of the at least two sixth mounting plates is arranged parallel to the width direction of the fourth mounting plate so as to pass through the fourth mounting plate. The at least two fifth mounting plates and the at least two sixth mounting plates together form a second accommodating space.

[0037] Applying the technical solution of the present invention, the inspection device provided in this application realizes stable detection and reliable fixation of the single-cell voltage of the fuel cell stack through its unique elastic extension contact end (elastic unit in the detection structure) and fixed clamping structure (clamping structure). Specifically:

[0038] The design of the elastic unit allows it to deform from the initial state to the detection state during the process of extending into the component to be detected (such as the pores of the bipolar plate of an air-cooled fuel cell stack), significantly increasing the contact area with the wall surface of the component to be detected. This elastic deformation mechanism ensures the close fit of the detection unit with the internal structure of the fuel cell stack, thereby improving the accuracy and stability of voltage detection.

[0039] The setting of the clamping part provides a flexible means to fix the inspection device on the stack fixing structure (such as a screw). By adjusting the state of the clamping part, the inspection device can be firmly fixed on the structure to be installed. Even in harsh environments such as vibration, it can maintain the stability of its position, prevent falling off and dislocation, thereby ensuring the reliability of long-term detection.

[0040] The combined design of the elastic unit and the clamping part of this inspection device enables the inspection device to achieve convenient plug-and-play installation without changing the original structure of the fuel cell stack, greatly simplifying the installation process of the inspection device, reducing the operation difficulty, and improving the inspection efficiency.

[0041] Therefore, compared with the prior art, the inspection device of this application not only solves the problems of poor contact, unstable fixation, and complex installation in the existing inspection methods, but also significantly improves the accuracy of voltage detection and the convenience of device use, providing a more efficient and reliable technical means for the real-time monitoring and maintenance of fuel cell stacks.

Detailed implementation manners

[0049] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0050] Fuel cell technology, as a clean and efficient energy conversion method, has shown extremely high application potential in the transportation field in recent years. Especially in miniaturized and portable applications, air-cooled fuel cells have become the focus of attention due to their unique lightweight design, high power density, and simplified balance of plant (BOP) structure. However, with the increasing number of air-cooled fuel cells in practical applications, the technical problems existing therein are becoming increasingly prominent. Among them, the most critical one is the lack of a real-time monitoring mechanism for the single-cell voltage monitoring of the stack and abnormal working states (such as stack reversal).

[0051] Currently, most air-cooled fuel cell stacks are not equipped with an effective voltage inspection device. During actual operation, abnormal changes in the single-cell voltage inside the stack or stack reversal phenomena cannot be monitored in a timely manner, which often leads to performance degradation or even permanent damage of the entire fuel cell stack. Voltage inspection plays an irreplaceable role in the performance maintenance, fault diagnosis, and prevention of air-cooled fuel cells, but the application of existing technologies in this field is not yet mature.

[0052] In the field of water-cooled fuel cells, the voltage inspection connection methods mainly adopt pre-connection (welding), reserved hole bonding (gluing) and special terminal plug-in (plug-in) and other means. Although the pre-connection method can achieve stable connection, it needs to be customized during the bipolar plate production stage, which increases the production cost. Once the inspection device is damaged or the connection is poor, the stack must be disassembled and the bipolar plate must be replaced, which is complicated and costly. Although the adhesive inspection connection simplifies the installation process to a certain extent, the long-term stability of the adhesive is subject to the high temperature and high humidity environment of the fuel cell operation, and it is easy to have loose connections or corrosion, affecting the accuracy and reliability of the inspection. The plug-in inspection connection adopts a special terminal design to achieve connection with the stack through precise matching, but due to the thickness of the bipolar plate, the contact area is limited and the clamping force is weak. Especially in high-intensity vibration or harsh environments, the connection stability is difficult to guarantee.

[0053] In addition, although the contact inspection method can directly contact the side wall of the battery stack, due to differences in the battery stack assembly process, thermal expansion and contraction deformation of the bipolar plates when stacked, and temperature changes in high and low temperature environments, the spacing consistency between the bipolar plates will be reduced, which in turn affects the connection stability between the inspection terminal and the bipolar plate plug-in, making it easy to have problems such as misalignment, short circuit, and poor contact, reducing the reliability and durability of the inspection system.

[0054] The technical purpose of this application is to provide a patrol inspection device to solve the above problems, including:

[0055] A clamping structure 10, wherein the clamping structure 10 has a clamping portion 101, so as to fix the inspection device on the structure to be installed through the clamping portion 101;

[0056] The detection structure 20 is arranged on the clamping structure 10. The detection structure 20 includes a deformable detection structure 20. The detection structure 20 has an initial state and a detection state. When the detection structure 20 is in the detection state, it is used to detect the component to be detected. When the detection structure 20 extends into the component to be detected and is subjected to the force of the component to be detected, the detection structure 20 is converted from the initial state to the detection state, and the component to be detected is detected.

[0057] like Figure 1 As shown, the inspection device clamping structure 10 provided in the present application has a clamping portion 101, through which the inspection device can be fixed on the structure to be installed. A detection structure 20 is arranged on the clamping structure 10, and the detection structure 20 includes an elastic unit, which is deformable. The detection structure 20 has a detection state and an initial state. When the detection structure 20 is in the detection state, as shown in FIG. Figure 1As shown, the detection structure 20 in the initial state is placed into the component to be detected. The component to be detected presents a rectangular shape in this embodiment, and the detection structure 20 can just extend into the interior of the component to be detected. During the process of the detection structure 20 extending into the component to be detected, the state of the detection structure 20 changes from Figure 1 the initial state in to the detection state, so as to increase the contact area between the detection structure 20 and the component to be detected, and realize the detection of the component to be detected.

[0058] The inspection device provided by the present application realizes the stable detection and reliable fixation of the single-cell voltage of the fuel cell stack through its unique elastic extension contact end (the elastic unit in the detection structure 20) and the fixed clamping structure (the clamping structure 10). Specifically:

[0059] The design of the elastic unit allows it to deform from the initial state to the detection state during the process of extending into the component to be detected (such as the pores of the bipolar plate of the air-cooled fuel cell stack), significantly increasing the contact area with the wall surface of the component to be detected. This elastic deformation mechanism ensures the close fit between the detection unit and the internal structure of the fuel cell stack, thereby improving the accuracy and stability of voltage detection.

[0060] The setting of the clamping portion 101 provides a flexible means to fix the inspection device on the stack fixing structure (such as a screw). By adjusting the state of the clamping portion, the inspection device can be firmly fixed on the structure to be installed. Even in harsh environments such as vibration, it can maintain the stability of its position, prevent falling off and misalignment, thereby ensuring the reliability of long-term detection.

[0061] The combined design of the elastic unit and the clamping portion 101 of the inspection device enables the inspection device to achieve convenient plug-and-play installation without changing the original structure of the stack, greatly simplifies the installation process of the inspection device, reduces the operation difficulty, and improves the inspection efficiency.

[0062] Therefore, compared with the prior art, the inspection device of the present application not only solves the problems of poor contact, unstable fixation, and complex installation in the existing inspection methods, but also significantly improves the accuracy of voltage detection and the convenience of device use, providing a more efficient and reliable technical means for the real-time monitoring and maintenance of fuel cell stacks.

[0063] Furthermore, the detection structure 20 further includes: a fixing unit 202. The fixing unit 202 includes fixing components 2021 provided at both ends of the detection structure 20 to fix the detection structure 20 on the clamping structure 10 through one of the fixing components 2021.

[0064] Further, the detection structure 20 includes: a plurality of detection components 2011, each of the plurality of detection components 2011 is an elastic detection piece, and both ends of the plurality of detection components 2011 are respectively connected to two fixing components 2021;

[0065] Among them, the plurality of detection components 2011 together enclose a detection structure 20 with a first space inside. When detecting the component to be detected, the plurality of detection components 2011 move towards the direction close to the first space, so that the detection structure 20 is in a detection state. After the detection of the component to be detected is completed, the plurality of detection components 2011 move away from the first space, so that the detection structure 20 is in an initial state.

[0066] Specifically, the detection structure 20 includes a plurality of detection components 2011, and each of the plurality of detection components 2011 is an elastic detection piece, which can be bent when subjected to an external force and return to its original state when the external force disappears. When detecting the component to be detected, the plurality of detection components 2011 are subjected to the external force applied by the component to be detected. Therefore, the plurality of detection components 2011 move closer to the internal first space. And the detection component 2011 itself has a certain elastic force. Therefore, when the detection component 2011 comes out of the component to be detected, it will gradually return from the detection state to the initial state.

[0067] Since the elastic detection piece can adaptively adjust its contact state according to the shape and size of the internal space of the component to be detected, when deforming from the initial state to the detection state, it can fit more closely to the surface of the component to be detected, increasing the contact area, thereby improving the stability and accuracy of voltage detection, reducing the problems of virtual connection and poor contact, and enhancing the adaptability and flexibility: The design of the elastic detection piece allows the inspection device to adapt to components to be detected with different sizes and shapes. Even when facing the slight changes of bipolar plates or the size fluctuations caused by thermal expansion and contraction, it can maintain good contact, making the inspection device have stronger adaptability and flexibility. Simplify maintenance and operation: The dynamic deformation and automatic recovery characteristics of the elastic detection piece when subjected to an external force make the installation and disassembly process of the inspection device more simple and fast. Without additional tools or adjustments, the device can be quickly plugged in and positioned, improving the maintainability and operation efficiency of the inspection device. The recovery ability of the elastic detection piece can effectively reduce the mechanical damage to the inspection device and the component to be detected during the installation and disassembly process, extend the service life of the device, and at the same time avoid the damage to the component to be detected caused by improper installation, reducing the maintenance cost.

[0068] Further, both ends of the detection structure 20 are fixedly connected to the fixing unit 202; and / or,

[0069] The fixing unit 202 is fixedly connected to the clamping structure 10.

[0070] Further, a first clamping member 102 has a first connection end, and a first arc-shaped opening is provided on the first connection end;

[0071] A second clamping member 103 has a second connection end, and a second arc-shaped opening is provided on the second connection end;

[0072] Wherein, the first clamping member 102 and the second clamping member 103 are rotatably connected, so that when detecting the component to be detected, the first clamping member 102 and the second clamping member 103 move relatively closer to each other, so that the first arc-shaped opening and the second arc-shaped opening jointly form a clamping portion 101.

[0073] Specifically, the first clamping member 102 has a first connection end, and a first arc-shaped opening is provided on the first connection end. The second clamping member 103 has a second connection end, and a second arc-shaped opening is provided on the second connection end. The first arc-shaped opening and the second arc-shaped opening jointly form an arc similar to 3 / 4. Normally, the first clamping member 102 and the second clamping member 103 are straight. When it is necessary to detect the component to be detected, the first clamping member 102 and the second clamping member 103 need to be bent into Figure 1 the shape in []. Then, the inspection device is fixed to the structure to be installed through the middle clamping portion 101.

[0074] The first clamping member 102 and the second clamping member 103 are rotatably connected, and can dynamically adjust their clamping angles according to the shape of the structure to be installed, so as to fix the inspection device more firmly. When the first arc-shaped opening and the second arc-shaped opening jointly form a clamping portion 101 similar to a 3 / 4 arc, this structural design can provide a greater clamping force to ensure the stability of the device on the stack screw or other fixed structures. Even in the vibration and impact during vehicle operation or in harsh environments, it can maintain a good fixing effect and prevent the device from loosening or falling off.

[0075] Before installation, the inspection device is straight, which enables the device to easily pass through the narrow space of the stack for positioning. After being bent into a specific shape under the action of an external force, through the cooperation of the first clamping member 102 and the second clamping member 103, the fixing of the device can be quickly realized. This design not only simplifies the installation steps, but also improves the installation efficiency, making the installation of the inspection device more convenient and fast.

[0076] The rotatable connection design of the first clamping member 102 and the second clamping member 103 allows the inspection device to be adjusted in a softer manner during the installation and disassembly processes, reducing the direct pressure on the stack structure, thereby reducing the risk of mechanical damage caused by improper installation and protecting the structural integrity and functionality of the stack and the inspection device.

[0077] The above design of the inspection device enables maintenance personnel to easily install and disassemble the device without using special tools or performing complex operations. This not only simplifies the maintenance process but also improves the maintainability of the inspection device. When it is necessary to inspect or replace the fuel cell stack, the inspection device can be quickly removed from and reinstalled on the fuel cell stack, greatly saving maintenance time and costs.

[0078] Furthermore, the clamping structure 10 further includes:

[0079] A first hinge hole, opened on the first connection end;

[0080] A second hinge hole, opened on the second connection end;

[0081] A connecting member 104, the connecting member 104 is rotatably passed through the first hinge hole and the second hinge hole so that the first clamping member 102 and the second clamping member 103 are rotatably arranged.

[0082] Specifically, the clamping structure 10 further includes a first hinge hole provided at the first connection end and close to the first arc-shaped opening, and a second hinge hole provided at the second connection end and close to the second arc-shaped opening. It also includes a connecting member 104 that cooperates with the first hinge hole and the second hinge hole. The connecting member 104 is a pin shaft in this embodiment. By using the pin shaft, the first clamping member 102 and the second clamping member 103 can be rotatably connected together.

[0083] The hinge structure design enables the first clamping member 102 and the second clamping member 103 to rotate freely, so that they can be adaptively adjusted according to the shape and size of the structure to be installed. This flexibility ensures that the inspection device can be firmly fixed on the fuel cell stack screws of different sizes, improving the adaptability of the device to various application scenarios.

[0084] The use of the hinge structure allows the inspection device to maintain a straight state during installation for easy initial positioning. When it needs to be fixed, by rotating the first clamping member 102 and the second clamping member 103 to form a clamping state, it can be quickly fixed on the fuel cell stack screw. When disassembling, reverse operation can easily release the fixation, greatly simplifying the installation and disassembly steps and improving work efficiency.

[0085] The hinge design realized through connecting members such as pin shafts avoids directly applying excessive force on the clamping members, reduces wear and damage of the components during rotation, and extends the service life of the inspection device.

[0086] The hinge structure combines the first arc-shaped opening and the second arc-shaped opening to form a clamping portion 101 similar to a closed loop. This structure provides greater stability in the fixed state, reduces the possibility of the inspection device being displaced due to vibration or external forces, and ensures the continuity of the inspection process and the accuracy of data.

[0087] Furthermore, the clamping structure 10 further includes:

[0088] A first wire harness fixing part 105 is arranged on the side of the first clamping member 102 away from the first arc-shaped opening. The first wire harness fixing part 105 extends along the length direction of the first clamping member 102, and a first accommodation space for accommodating the wire harness is formed in the first wire harness fixing part 105.

[0089] Furthermore, the first wire harness fixing part 105 includes:

[0090] A first mounting plate 1051 is arranged on the side of the first clamping member 102 away from the first arc-shaped opening;

[0091] At least two second mounting plates 1052 are oppositely arranged on both sides in the width direction of the first mounting plate 1051. The at least two second mounting plates 1052 extend along the length direction of the first clamping member 102, and the width direction of the at least two second mounting plates 1052 is perpendicular to the width direction of the first mounting plate 1051;

[0092] At least two third mounting plates 1053 are oppositely arranged on the side of the at least two second mounting plates 1052 away from the first mounting plate 1051. The width direction of the at least two third mounting plates 1053 is arranged parallel to the width direction of the first mounting plate 1051, so as to jointly form the first accommodation space through the first mounting plate 1051, the at least two second mounting plates 1052 and the at least two third mounting plates 1053.

[0093] Specifically, as Figure 2 , Figure 3 and Figure 4 shown, the clamping structure 10 further includes a first wire harness fixing part 105 arranged on the side of the first clamping member 102 away from the first arc-shaped opening. The wire harness can be fixed on the clamping structure 10 through the first accommodation space in the first wire harness fixing part 105.

[0094] The design of the first wire harness fixing part 105 forms a space for accommodating and fixing the wire harness through multiple panels, ensuring that the wire harness will not loosen or fall off when subjected to external vibration or tension, improving the stability of the wire harness connection, which is crucial for ensuring the continuity of voltage inspection and the accuracy of data.

[0095] The first wire harness fixing part 105 extends along the length direction of the first clamping member 102. This layout method cleverly utilizes the space of the clamping structure, avoiding the precious space inside the stack occupied by additional wire harness fixing devices, which is beneficial to realizing the compact design and lightweight of the stack.

[0096] The first wire harness fixing part 105 formed by the first mounting plate 1051, the second mounting plate 1052, and the third mounting plate 1053 can conveniently organize and fix the wire harness, reduce the possibility of wire harness entanglement and chaos, and improve the maintainability and operation efficiency of the inspection device.

[0097] The design of the first wire harness fixing part 105 not only realizes the fixing of the wire harness (the wire harness in this embodiment is Figure 1 the part extending from the first wire harness fixing part 105, and the part extending from the second wire harness fixing part 106, and it can be seen from Figure 1 that the two wire harnesses cross each other), but also provides additional insulation protection to prevent the wire harness from directly contacting the stack or other metal components, reducing the risk of short circuits and other electrical safety problems.

[0098] Furthermore, the clamping structure 10 further includes:

[0099] A second wire harness fixing part 106, which is arranged on the side of the second clamping member 103 away from the second arc-shaped opening. The second wire harness fixing part 106 extends along the length direction of the second clamping member 103, and a second accommodation space for accommodating the wire harness is formed inside the second wire harness fixing part 106.

[0100] Furthermore, the second wire harness fixing part 106 includes:

[0101] A fourth mounting plate, which is arranged on the side of the second clamping member 103 away from the second arc-shaped opening;

[0102] At least two fifth mounting plates 1061, which are oppositely arranged on both sides in the width direction of the fourth mounting plate. The at least two fifth mounting plates 1061 extend along the length direction of the second clamping member 103, and the width direction of the at least two fifth mounting plates 1061 is perpendicular to the width direction of the fourth mounting plate;

[0103] At least two sixth mounting plates 1062, which are oppositely arranged on the side of the at least two fifth mounting plates 1061 away from the fourth mounting plate. The width direction of the at least two sixth mounting plates 1062 is arranged parallel to the width direction of the fourth mounting plate, so as to jointly form the second accommodation space through the fourth mounting plate, the at least two fifth mounting plates 1061, and the at least two sixth mounting plates 1062.

[0104] The second wire harness fixing part 106 and the first wire harness fixing part 105 form a symmetric wire harness fixing mechanism, improving the symmetry and balance of wire harness fixing, ensuring the stability on both sides of the inspection device, and further enhancing the fixing effect of the entire device and the safety of the wire harness.

[0105] The provision of the second accommodation space not only provides a fixing point for the wire harness, but also offers additional physical protection for the wire harness, preventing the wire harness from being worn or squeezed in a complex environment, and enhancing the service life and reliability of the wire harness.

[0106] By arranging the wire harness fixing part on the back sides of the first clamping member 102 and the second clamping member 103, the structural space of the inspection device is fully utilized, the additional components required for wire harness fixing are reduced, which helps to achieve a compact design of the inspection device and reduces the occupation of the internal space of the fuel cell stack.

[0107] The bilateral wire harness fixing design provides a convenient interface, facilitating maintenance personnel to inspect, replace or upgrade the wire harness. Without disassembling the entire inspection device, they only need to operate the corresponding wire harness fixing part, which improves the maintenance efficiency and convenience.

[0108] The arrangement of the second wire harness fixing part 106 ensures the electrical isolation between the wire harness and the fuel cell stack body, reduces the risk of electrical interference and short circuit, and improves the electrical safety performance of the entire inspection system.
