Description

Technical Field

[0001] This utility model relates to the field of power supply device technology, specifically to an anti-vibration protection structure for a hydrogen energy power supply device. Background Technology

[0002] With increasing environmental awareness and growing demand for clean energy, hydrogen energy, as an efficient and clean energy form, is being used more and more widely in the power supply sector. Hydrogen-powered devices typically include core components such as hydrogen storage tanks, fuel cell stacks, and electronic control units. These components work together to convert the chemical energy of hydrogen into electrical energy to power external devices.

[0003] According to Chinese Patent Publication No. CN 110797486 A3, a hydrogen energy power generation device is disclosed, including a base.

An anti-slip pad is fixedly connected to the bottom of the main body of the power generation device, and fixing plates are fixedly connected to the top of the base and to both the left and right sides of the main body of the power generation device. This hydrogen energy power generation device, by setting a baffle on the top of the main body of the power generation device and a baffle block on the outside of the heat conduction groove to prevent water from flowing into the device when it is outdoors, effectively prevents rainwater from flowing into the device from the heat dissipation points.

Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An anti-vibration protection structure for a hydrogen energy power supply device includes a buffer mechanism, and a movable mechanism is provided at the bottom of the buffer mechanism;

[0008] The buffer mechanism includes a base plate, with support blocks fixedly connected to the top left and right sides of the base plate. A connecting rod is fixedly connected to the inner side of each support block. Slider blocks are slidably connected to the left and right surfaces of the connecting rod. Springs are fixedly connected to the opposite sides of each slider. A first support rod is fixedly connected to the top of each slider. A connecting frame is rotatably connected to the surface of each first support rod. A hydraulic damper is bolted to the top of each support block. A mounting base is bolted to the top of each hydraulic damper. A connecting frame is fixedly connected to the bottom of the mounting base. Second support rods are fixedly connected to the left and right sides of the connecting frame. A hydrogen storage tank, a fuel cell stack, and an electronic control unit are installed inside the mounting base. An operation panel is located at the front end of the mounting base. A ventilation hole is opened at the rear of the mounting base. A dustproof net is fixedly connected inside the ventilation hole, and a fan is installed at the front end of the dustproof net.

[0009] Preferably, the two springs are respectively sleeved on the left and right sides of the connecting rod, and the ends of the two springs away from the slider are respectively fixedly connected to the inner sides of the two support blocks.

[0010] Preferably, the ends of the two connecting frames away from the first support rod are rotatably connected to the surfaces of the two second support rods, respectively.

[0011] Preferably, there are six hydraulic dampers, and the six hydraulic dampers are arranged in groups of three, located on the top of the two support blocks and on the left and right sides of the bottom of the mounting base in a linear array.

[0012] Preferably, there are three connecting rods and three connecting frames. The three connecting rods are arranged in a linear array inside the two support blocks, and the three connecting frames are arranged in a linear array at the bottom of the mounting base.

[0013] Preferably, the moving mechanism includes casters and push rods.

[0014] Preferably, four casters are provided, and the four casters are fixedly connected to the four corners of the bottom of the base plate. Two push rods are provided, and the two push rods are fixedly connected to the left and right sides of the rear of the base plate.

[0015] Compared with the prior art, the beneficial effects of the earthquake-resistant protection structure of the hydrogen energy power supply device of this utility model are:

[0016] First, after moving the device to a suitable position, the mounting base in the buffer mechanism houses a hydrogen storage tank, a fuel cell stack, and an electronic control unit. These components together constitute the core power generation system of the hydrogen-powered device. Operators use the control panel at the front of the mounting base to set relevant parameters and start the device. This allows the fuel cell stack to utilize the hydrogen stored in the hydrogen storage tank for a chemical reaction, generating electricity, which is then managed and distributed by the electronic control unit to power external equipment. When the device is subjected to vibration, the base plate transmits the vibration to the support block. The sliders slidably connected to the left and right surfaces of the connecting rod will slide along the connecting rod. Since springs are fixedly connected to opposite sides of the two sliders, and the ends of the springs furthest from the sliders are respectively connected to the two… The inner sides of each support block are fixedly connected, and the springs undergo elastic deformation during the sliding of the slider, absorbing and buffering some of the vibration energy, thereby reducing the impact of vibration on the equipment inside the upper mounting base. Simultaneously, the two first support rods are rotatably connected to the second support rods fixedly connected to the left and right sides of the connecting frame via a connecting frame. This structure, during vibration, can further disperse and dissipate vibration energy through the relative movement between the components, achieving a good buffering and shock absorption effect. Six hydraulic dampers, grouped in sets of three, are linearly arrayed on the top of the two support blocks and the left and right sides of the bottom of the mounting base. The hydraulic dampers have unique damping characteristics; when the device is subjected to vibration, they can absorb and buffer vibration through the flow of internal fluid and the control of valves. This generates a damping force opposite to the direction of vibration, effectively suppressing the vibration amplitude and speed of the device, keeping it relatively stable during vibration, and preventing damage to internal equipment due to severe vibration. This greatly improves the reliability and stability of the device in complex vibration environments. A ventilation hole is provided at the rear of the mounting base, with a dustproof net fixedly connected inside. A fan is installed at the front end of the dustproof net. During device operation, components such as the hydrogen storage tank, fuel cell stack, and electronic control unit generate heat. When the fan is activated, it accelerates the airflow inside the mounting base, expelling heat through the ventilation hole for effective heat dissipation. Simultaneously, the dustproof net prevents external dust and debris from entering the mounting base, avoiding dust contamination. To prevent internal equipment from becoming contaminated or damaged, and to ensure the stable performance and service life of the device during long-term operation, a linkage buffer structure composed of springs, sliders, support rods, and connecting frames is used. During vibration, the structure can absorb, disperse, and dissipate vibration energy through elastic deformation and relative movement with the components. Six linearly arrayed hydraulic dampers, with their unique damping characteristics, precisely suppress vibration amplitude and velocity, effectively stabilizing the device. The combined effect of these two components greatly reduces the impact of vibration on core equipment such as the hydrogen storage tank, fuel cell stack, and electrical control unit within the mounting base. This significantly improves the reliability, stability, and service life of the device in complex vibration environments, laying a solid foundation for the safe and stable operation of the equipment and ensuring its safe operation.

[0017] Secondly, when the hydrogen power supply device needs to be moved to a designated location, the operator only needs to hold the push rods located on the left and right sides behind the base plate and apply pushing or pulling force to the device. Since four universal wheels are fixedly connected to the four corners of the bottom of the base plate, the universal wheels can rotate flexibly, thereby easily changing the direction of movement of the device and realizing convenient transfer of the device between different locations.

[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] Please refer to the earthquake-resistant protection structure of a hydrogen energy power supply device according to this specific embodiment. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It includes a buffer mechanism 1, and a moving mechanism 2 is provided at the bottom of the buffer mechanism 1;

[0026] The buffer mechanism 1 includes a base plate 101. Support blocks 102 are fixedly connected to the top left and right sides of the base plate 101. A connecting rod 103 is fixedly connected to the inner side of each support block 102. Sliding sliders 104 are slidably connected to the left and right surfaces of the connecting rod 103. Springs 105 are fixedly connected to opposite sides of each slider 104. First support rods 106 are fixedly connected to the top of each slider 104. Connecting frames 107 are rotatably connected to the surfaces of each first support rod 106. The tops of the two support blocks 102 are fixedly connected with bolts. The hydraulic damper 108 has a mounting base 109 fixedly connected to its top with bolts. A connecting frame 110 is fixedly connected to the bottom of the mounting base 109. Second support rods 111 are fixedly connected to both sides of the connecting frame 110. A hydrogen storage tank 112, a fuel cell stack 113, and an electronic control unit 114 are installed inside the mounting base 109. An operation panel 115 is provided at the front end of the mounting base 109. A ventilation hole is provided at the rear of the mounting base 109. A dustproof net 116 is fixedly connected inside the ventilation hole. A fan 117 is installed at the front end of the dustproof net 116.

[0027] After the device is moved to a suitable position using the above technical solution, the hydrogen storage tank 112, fuel cell stack 113, and electronic control unit 114 are installed in the mounting base 109 of the buffer mechanism 1. These components together constitute the core power generation system of the hydrogen power supply device. The operator sets relevant parameters and starts the device through the operation panel 115 at the front end of the mounting base 109, so that the fuel cell stack 113 uses the hydrogen stored in the hydrogen storage tank 112 to carry out a chemical reaction to generate electrical energy, which is managed and distributed by the electronic control unit 114 to supply power to external equipment. When the device is vibrated, the base plate 101 transmits the vibration to the support block 102, and the sliders 104 that are slidably connected to the left and right sides of the connecting rod 103 will slide along the connecting rod 103. The movement is facilitated by springs 105 fixedly connected to opposite sides of the two sliders 104, with the ends of the springs 105 away from the sliders 104 respectively fixedly connected to the inner sides of the two support blocks 102. The springs 105 undergo elastic deformation during the sliding of the sliders 104, absorbing and buffering some of the vibration energy, thereby reducing the impact of vibration on the equipment inside the upper mounting base 109. Simultaneously, the two first support rods 106 are rotatably connected to the second support rods 111 fixedly connected to the left and right sides of the connecting frame 110 via connecting brackets 107. This structure further disperses and dissipates vibration energy through the relative movement between components during vibration, achieving a good buffering and shock absorption effect. The six hydraulic dampers 108 are grouped in sets of three and located on the two support blocks 102 respectively. The top and bottom left and right sides of the mounting base 109 are linearly arrayed. The hydraulic damper 108 has unique damping characteristics. When the device is subjected to vibration, it can generate a damping force opposite to the vibration direction through the flow of internal liquid and valve control, effectively suppressing the vibration amplitude and speed of the device, keeping the device relatively stable during vibration, and avoiding damage to internal equipment due to severe vibration. This greatly improves the reliability and stability of the device in complex vibration environments. A ventilation hole is provided at the rear of the mounting base 109, and a dustproof net 116 is fixedly connected inside the ventilation hole. A fan 117 is installed at the front end of the dustproof net 116. During the operation of the device, components such as the hydrogen storage tank 112, fuel cell stack 113, and electronic control unit 114 will generate heat. After the fan 117 is started, it accelerates the airflow inside the mounting base 109, expelling heat to the outside of the device through the ventilation holes, achieving effective heat dissipation. Simultaneously, the dust filter 116 prevents external dust and debris from entering the mounting base 109, avoiding contamination and damage to the internal equipment and ensuring stable performance and lifespan during long-term operation. The linkage buffer structure composed of the spring 105, slider 104, support rod, and connecting frame 107 efficiently absorbs, disperses, and dissipates vibration energy through elastic deformation and relative movement with the components during vibration. The six linearly arrayed hydraulic dampers 108, with their unique damping characteristics, precisely suppress vibration amplitude and speed, effectively stabilizing the device. The two work synergistically.This significantly reduces the impact of vibration on core equipment such as the hydrogen storage tank 112, fuel cell stack 113, and electrical control unit 114 within the mounting base 109, substantially improving the reliability, stability, and service life of the device under complex vibration environments. This lays a solid foundation for the safe and stable operation of the equipment and ensures its safe operation.

[0028] Specifically, two springs 105 are respectively sleeved on the left and right sides of the connecting rod 103, and the ends of the two springs 105 away from the slider 104 are respectively fixedly connected to the inner side of the two support blocks 102.

[0029] With the above technical solution, the spring 105 is sleeved on the left and right sides of the connecting rod 103, and its end away from the slider 104 is fixed to the inner side of the support block 102. It absorbs vibration energy through elastic deformation and assists in shock resistance.

[0030] Specifically, the ends of the two connecting brackets 107 that are away from the first support rod 106 are rotatably connected to the surfaces of the two second support rods 111, respectively.

[0031] Through the above technical solution, one end of the connecting frame 107 is connected to the first support rod 106, and the other end is connected to the surface of the second support rod 111. The movable support structure disperses vibration energy and enhances seismic performance.

[0032] Specifically, there are six hydraulic dampers 108. The six hydraulic dampers 108 are arranged in groups of three, located on the top of the two support blocks 102 and on the left and right sides of the bottom of the mounting base 109 in a linear array.

[0033] Through the above technical solution, six hydraulic dampers 108 are grouped into threes and installed on the top of the two support blocks 102 and the bottom left and right sides of the mounting base 109 in a linear array, providing multi-position support and buffering to consume vibration energy.

[0034] Specifically, there are three connecting rods 103 and three connecting frames 110. The three connecting rods 103 are arranged in a linear array inside the two support blocks 102, and the three connecting frames 110 are arranged in a linear array at the bottom of the mounting base 109.

[0035] Through the above technical solution, three connecting rods 103 and three connecting frames 110 are set. The connecting rods 103 are arranged in a linear array inside the two support blocks 102, and the connecting frames 110 are also arranged in a linear array at the bottom of the mounting base 109. This distribution of multiple connecting rods 103 and connecting frames 110 can provide more uniform and stable support for the entire buffer mechanism 1. When the device is subjected to vibration, multiple connecting rods 103 and connecting frames 110 can work together to disperse the vibration energy to various parts, avoid excessive local stress that could lead to structural damage, and thus better protect the components inside the device and enhance the seismic protection effect.

[0036] Specifically, the moving mechanism 2 includes a caster wheel 201 and a push rod 202.

[0037] With the above technical solution, when it is necessary to move the hydrogen power supply device to a designated location, the operator only needs to hold the push rods 202 located on the left and right sides behind the base plate 101 and apply pushing or pulling force to the device. Since four universal wheels 201 are fixedly connected to the four corners of the bottom of the base plate 101, the universal wheels 201 can rotate flexibly, thereby easily changing the direction of movement of the device and realizing convenient transfer of the device between different locations.

[0038] Specifically, there are four casters 201, which are fixedly connected to the four corners of the bottom of the base plate 101. There are two push rods 202, which are fixedly connected to the left and right sides of the rear of the base plate 101.

[0039] Through the above technical solution, four omnidirectional wheels 201 are fixed at the four corners of the base plate 101, providing stable support and flexible steering. Two push rods 202 are located on the left and right sides behind the base plate 101, facilitating the application of force with both hands and improving the ease of movement.

[0040] Its working principle is as follows:

[0041] With the above technical solution, when it is necessary to move the hydrogen power supply device to a designated location, the operator only needs to hold the push rods 202 located on the left and right sides behind the base plate 101 and apply pushing or pulling force to the device. Since four universal wheels 201 are fixedly connected to the four corners of the bottom of the base plate 101, the universal wheels 201 can rotate flexibly, thereby easily changing the direction of movement of the device and realizing convenient transfer of the device between different locations. After the device is moved to a suitable location, the internal wiring connections of the hydrogen storage tank 112, fuel cell stack 113, electronic control unit 114, operation panel 115 and fan 117 are existing well-known technologies in the art and will not be described in detail here. Since the hydrogen storage tank 112 and fuel cell stack 113 are installed in the mounting base 109 in the buffer mechanism 1, The fuel cell stack 113 and the electronic control unit 114 together constitute the core power generation system of the hydrogen energy power supply device. The operator sets relevant parameters and starts the device through the operation panel 115 at the front end of the mounting base 109, so that the fuel cell stack 113 uses the hydrogen stored in the hydrogen storage tank 112 to carry out a chemical reaction to generate electrical energy, which is managed and distributed by the electronic control unit 114 to supply power to external equipment. When the device is vibrated, the base plate 101 transmits the vibration to the support block 102. The sliders 104, which are slidably connected to the left and right surfaces of the connecting rod 103, will slide along the connecting rod 103. Since springs 105 are fixedly connected to the opposite sides of the two sliders 104, and the ends of the springs 105 away from the sliders 104 are respectively fixed to the inner sides of the two support blocks 102. In the fixed connection, the spring 105 undergoes elastic deformation during the sliding of the slider 104, absorbing and buffering some of the vibration energy, thereby reducing the impact of vibration on the equipment inside the upper mounting base 109. Simultaneously, the two first support rods 106 are rotatably connected to the second support rods 111, which are fixedly connected to the left and right sides of the connecting frame 110, via the connecting bracket 107. This structure can further disperse and dissipate vibration energy during vibration through the relative movement between the components, achieving a good buffering and shock absorption effect. The hydraulic damper 108 is existing technology and will not be described in detail here. The six hydraulic dampers 108 are arranged in groups of three, linearly arrayed on the top of the two support blocks 102 and the left and right sides of the bottom of the mounting base 109. The hydraulic dampers 108 have unique... The damping characteristics of the device allow it to generate a damping force opposite to the direction of vibration through the flow of internal liquid and valve control when the device is subjected to vibration. This effectively suppresses the vibration amplitude and speed, keeping the device relatively stable during vibration and preventing damage to internal equipment due to severe vibration. This greatly improves the reliability and stability of the device in complex vibration environments. A ventilation hole is provided at the rear of the mounting base 109, and a dustproof net 116 is fixedly connected inside the ventilation hole. A fan 117 is installed at the front end of the dustproof net 116. During device operation, components such as the hydrogen storage tank 112, fuel cell stack 113, and electronic control unit 114 generate heat. After the fan 117 is activated, it accelerates the airflow inside the mounting base 109, expelling the heat to the outside of the device through the ventilation hole.This design achieves effective heat dissipation. Simultaneously, the dust filter 116 prevents external dust and debris from entering the mounting base 109, avoiding dust contamination and damage to the internal equipment, and ensuring stable performance and extended service life of the device during long-term operation.
