[0024] Example 1:
[0025] like Figures 1 to 4 As shown, this embodiment provides a fixing structure for installing a hydrogen production device, including a frame 10 for accommodating the hydrogen production device. A base plate 11 is provided inside the frame 10, and a buffer is provided between the base plate 11 and the bottom of the frame 10. A vertical plate 12 is connected to the base plate 11, and a clamping mechanism for clamping the hydrogen production device is provided on the vertical plate 12. A liquid spraying mechanism is also provided between the base plate 11 and the bottom of the frame 10. When the base plate 11 moves under the gravity of the hydrogen production device, the clamping mechanism applies pressure to the hydrogen production device from the side, and the liquid spraying mechanism cleans the surface of the hydrogen production device.
[0026] In the installation and operation process of the hydrogen production equipment, the traditional fixed structure has the problems of unstable fixation, lack of cleaning function and inability to effectively buffer the impact of the equipment, etc. The present scheme aims to solve these problems and ensure the stable and efficient operation of the hydrogen production equipment. When working, the hydrogen production equipment is placed on the bottom plate 11, and the gravity of the equipment makes the bottom plate 11 move downward against the elastic force of the spring 14. The downward movement of the bottom plate 11 drives the vertical plate 12 to move downward synchronously, and the wedge plate 122 on the vertical plate 12 pushes the wheel 133, and the wheel 133 rolls to make the connecting rod 131 move in the sleeve 132, thereby driving the abutting plate 13 to move towards the hydrogen production equipment. Through the symmetrically arranged clamping units on both sides, the hydrogen production equipment is tightly clamped from the side, ensuring that the equipment will not shake and displace during operation, greatly improving the stability of the equipment operation and avoiding the reduction of hydrogen production efficiency and equipment damage due to unstable equipment. At the same time, the downward movement of the bottom plate 11 drives the straight rod 16 and the piston plate 161 to move downward in the cylinder 15, compressing the space of the cylinder 15, so that the liquid passes through the water pipe 17, the first pipeline and the second pipeline under the action of pressure, and finally is sprayed from the nozzles 121 evenly distributed on the vertical plate 12, thereby cleaning the surface of the hydrogen production equipment, effectively removing dust, impurities and other pollutants on the surface of the equipment, preventing them from affecting the heat dissipation and erosion of internal components, prolonging the service life of the equipment and reducing maintenance costs. In practical application, the buffer can be selected from springs 14 with different elastic coefficients, and the appropriate spring 14 can be selected according to the weight and operating environment of the hydrogen production equipment to achieve the best buffering effect. For the clamping mechanism, the wheel 133 can be replaced by a sliding block, and the movement of the abutting plate 13 can be achieved by the cooperation of the wedge plate 122 and the sliding block, which can also achieve the purpose of clamping the equipment. In the liquid spraying mechanism, the shape of the piston plate 161 can be adjusted according to the internal structure of the cylinder 15, such as using a circular or rectangular piston plate 161, as long as it can effectively compress the space of the cylinder 15 and drive the liquid to flow.
[0027] In the present embodiment, the clamping mechanism includes a wedge plate 122 and an abutting plate 13, the wedge plate 122 is arranged on the vertical plate 12, the inner wall of the frame 10 is fixed with a sleeve 132, the sleeve 132 is movably arranged with a connecting rod 131, one end of the connecting rod 131 is connected to the abutting plate 13, and the other end of the connecting rod 131 is rotatably connected with a wheel 133. When the vertical plate 12 moves downward, the abutting plate 13 can move towards the hydrogen production equipment.
[0028] When the vertical plate 12 moves downward due to the downward movement of the bottom plate 11, the wedge plate 122 pushes the wheel 133 to rotate, the wheel 133 drives the connecting rod 131 to slide in the sleeve 132, thereby pushing the abutting plate 13 to move towards the hydrogen production equipment, achieving clamping. In practical application, this structure uses mechanical transmission to stably and accurately apply clamping force to the equipment, ensuring stable operation of the equipment. The alternative solution can replace the wheel 133 with a roller sliding block, which can push the abutting plate 13 to move by cooperating with the wedge surface and the roller sliding block.
[0029] In the embodiment, the liquid spraying mechanism comprises a plurality of nozzles 121 arranged on the vertical plate 12 and a second pipeline arranged in the vertical plate 12 and communicated with the nozzles 121, and a straight rod 16 arranged on the bottom plate 11, one end of the straight rod 16 being connected to the bottom plate 11, the other end of the straight rod 16 being connected to a piston plate 161, the bottom of the frame 10 being provided with a cylinder 15 accommodating the piston plate 161 and matched with the piston plate 161, the bottom plate 11 being provided with a first pipeline communicated with the second pipeline, and the cylinder 15 and the first pipeline being provided with a water pipe 17 communicating the cylinder 15 and the first pipeline. When the bottom plate 11 moves downward, the piston plate 161 can be driven to compress the space of the cylinder 15, so that the liquid is sprayed to the surface of the hydrogen production equipment through the water pipe 17, the first pipeline, the second pipeline and the nozzles 121.
[0030] The bottom plate 11 drives the straight rod 16 to push the piston plate 161 to compress the cylinder 15, so that the liquid is sprayed from the nozzles 121 through the water pipe 17, the first pipeline and the second pipeline. In actual scenarios, the structure can realize automatic cleaning by liquid pressure driving, effectively remove impurities on the surface of the equipment, and prolong the service life of the equipment. Alternatively, the piston plate 161 can be replaced by a diaphragm structure, and the elastic deformation of the diaphragm is used to compress the liquid.
[0031] In the embodiment, the outer periphery of the wheel 133 is uniformly provided with a plurality of teeth to form a gear segment. When the vertical plate 12 drives the wedge-shaped plate 122 to move, the meshing of the gear segment and the wedge-shaped plate 122 can effectively avoid slipping, so that the movement of the abutting plate 13 is more stable and accurate. In actual application, the stability and reliability of the clamping mechanism can be further improved. Alternatively, a toothed protrusion is arranged on the surface of the wheel 133, which can also enhance the friction force with the wedge-shaped plate 122 and realize stable transmission.
[0032] In the embodiment, the buffer is a spring 14. When the hydrogen production equipment is placed on the bottom plate 11, the spring 14 is deformed under pressure to absorb the impact force generated when the equipment is placed. In actual application, the internal precision components of the hydrogen production equipment can be effectively protected to avoid damage caused by impact.
[0033] In the embodiment, the number of springs 14 is multiple, and the multiple springs 14 are uniformly arranged between the bottom plate 11 and the bottom of the frame 10. To ensure uniform distribution of the buffer force, multiple springs 14 are uniformly arranged between the bottom plate 11 and the bottom of the frame 10. When the hydrogen production equipment is placed to cause the bottom plate 11 to move downward, the multiple springs 14 are jointly stressed to make the bottom plate 11 move stably downward, avoiding tilting or damage of the equipment caused by uneven local stress.
[0034] In the embodiment, the number of nozzles 121 is multiple, and the multiple nozzles 121 are uniformly arranged on the vertical plate 12 and respectively communicated with the second pipeline.
[0035] Multiple nozzles 121 are evenly arranged on the vertical plate 12 and are all connected to the second pipe. When the piston plate 161 compresses the cylinder 15 to spray out liquid, the multiple nozzles 121 work simultaneously to rinse the equipment surface from different angles. In actual hydrogen production equipment cleaning, this ensures that there are no dead corners on the equipment surface and effectively removes stubborn stains.
[0036] Work process:
[0037] When the hydrogen production equipment is placed on the fixed base plate 11, the weight of the equipment causes the base plate 11 to move downwards, overcoming the elastic force of the springs 14 evenly distributed between it and the bottom of the frame 10. The descent of the base plate 11 causes the vertical plate 12 to move synchronously. The wedge plate 122 on the vertical plate 12 pushes the wheel 133. The wheel 133, equipped with a gear section, tightly engages with the wedge plate 122, causing the connecting rod 131 to slide within the sleeve 132. This, in turn, pushes the abutment plates 13 of the mirror-symmetrical first and second clamping units on both sides towards the hydrogen production equipment, firmly clamping the equipment from the side. Simultaneously, the descent of the base plate 11 causes the straight rod 16 to push the piston plate 161, compressing the space in the cylinder 15. This causes liquid to sequentially pass through the water pipe 17, the first pipe, and the second pipe, and is sprayed out from multiple nozzles 121 evenly distributed on both sides of the vertical plate 12, thoroughly cleaning the surface of the hydrogen production equipment. This achieves stable fixation and automatic cleaning of the equipment, ensuring stable operation of the hydrogen production equipment.
[0038] Example 2:
[0039] like Figure 1 As shown, based on the above embodiments, in this embodiment, the abutment plate 13, connecting rod 131, sleeve 132, wheel 133 and wedge plate 122 are combined to form a first clamping unit. Taking the midpoint of the base plate 11 in the horizontal length direction as a reference, a second clamping unit that is mirror-symmetrical to the first clamping unit is also included.
[0040] Using the midpoint of the horizontal length of the base plate 11 as a reference, mirror-symmetrical first and second clamping units are set up. In actual operation, when the hydrogen production equipment is placed and the base plate 11 is lowered, causing the vertical plate 12 to move, the wedge plates 122 of the clamping units on both sides simultaneously push the wheels 133, causing the connecting rod 131 to drive the abutment plate 13 to clamp synchronously from both sides of the equipment. This ensures that the equipment is subjected to uniform force in all directions, effectively preventing the equipment from shifting or shaking during operation, and greatly improving the stability of equipment operation.
[0041] In this embodiment, the nozzle 121, the second pipe, the first pipe and the water pipe 17 are combined to form a first spray unit. Taking the midpoint of the base plate 11 in the horizontal length direction as a reference, it also includes a second spray unit that is mirror-symmetrical to the first spray unit.
[0042] By setting the mirror symmetry of the first and second liquid spray units, both sides of the hydrogen production equipment can be fully cleaned. When the bottom plate 11 drives the piston plate 161 to compress the cylinder body 15, the liquid flows from the water pipes 17 on both sides into the first pipeline, and then is sprayed from the nozzles 121 on the vertical plates 12 on both sides through the second pipeline. In practical application, such as in an industrial hydrogen production workshop, impurities at different positions on the surface of the equipment can be effectively removed, and local corrosion or performance degradation of the equipment caused by incomplete cleaning can be avoided. If a small hydrogen production equipment is encountered, one of the liquid spray units can be closed to save cleaning liquid and energy consumption.
[0043] The above examples are only used to illustrate the technical solutions of the present disclosure, rather than limit them; although the present disclosure has been described in detail with reference to the foregoing examples, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacements for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
