Abstract
Description
Technical Field
[0001] This invention belongs to the field of energy recycling technology, specifically relating to a waste heat recovery device based on hydrogen-electric-thermal multi-energy coupling integrated energy. Background Technology
[0002] An integrated energy system based on the coupling of hydrogen, electricity, and heat, combined with a waste heat recovery device, is a highly efficient and low-carbon energy utilization solution. By integrating multiple energy forms (hydrogen, electricity, and heat) and waste heat recovery technology, this system can significantly improve energy utilization efficiency and reduce carbon emissions. The waste heat recovery device can be a heat exchanger.
[0003] After a period of use, the waste heat recovery device needs to be cleaned regularly. When cleaning the inside of the heat exchanger, the end cover at the top of the heat exchanger needs to be opened, and then a high-pressure water gun is used to clean and flush the tube bundle of the heat exchanger.
[0004] When using a high-pressure water gun to clean the inside of a heat exchanger, it may be necessary to disassemble some components for thorough cleaning. During this process, the operator needs to lower the high-pressure water gun. Due to the limited area of the operating platform on top of the heat exchanger, the high-pressure gun may fall from the top of the heat exchanger if it is not placed correctly. This requires the operator to climb down from the top of the heat exchanger to retrieve the water gun before continuing the cleaning work. In severe cases, the water gun that falls from the top of the heat exchanger may be damaged, making the cleaning work impossible, reducing the efficiency of heat exchanger cleaning, and greatly delaying the progress of heat exchanger cleaning. Utility Model Content

[0006] The specific technical solution adopted in this utility model is as follows:

[0010] In a preferred embodiment, the two ends of the protective rod are slidably connected to the interior of the corresponding protective tube, and a retaining screw is threadedly connected to the outer side of the protective tube at a position corresponding to the protective rod, with the end of the retaining screw near the protective rod extending into the interior of the protective tube.
[0011] In a preferred embodiment, a storage slot is provided on the top of the operating table at a position corresponding to the protective tube and the protective rod, and the storage slot is adapted to the protective tube and the protective rod at the corresponding positions.
[0012] In a preferred embodiment, the pressing and limiting assembly includes a limiting rod with both ends disposed at the bottom of both ends of the climbing ladder. Both ends of the limiting rod penetrate the interior of the climbing ladder and extend upwards. The portion of the limiting rod penetrating the climbing ladder is slidably connected to the climbing ladder, and a spring is provided on the outer wall of this portion of the climbing ladder. The top of the inner wall of the spring is fixedly connected to the outer wall of the limiting rod, and the bottom of the outer side of the spring is fixedly connected to the inner wall of the climbing ladder. A stop bar is fixedly connected between the two protective tubes. When the protective tubes and the protective rod are in a vertical state, the limiting rod is located behind the stop bar, and the outer side of the stop bar contacts the outer side of the limiting rod.
[0013] In a preferred embodiment, a pressing ring is formed in a semi-circular shape at the middle of the limiting rod, the pressing ring is located on the front of the end cap, and the blocking ring is fixedly connected to the middle position of the bottom outer side of the pressing ring.

At this time, the staff can promptly pull the water supply pipe to stop the high-pressure water gun from falling and simultaneously pull it back to the operating table through the water supply pipe, allowing the staff to continue working. This also prevents the high-pressure water gun from falling directly to the ground and interrupting the cleaning work, while avoiding damage to the high-pressure water gun, thus ensuring the normal progress of the cleaning work and improving its efficiency.
[0020] This practical device protects workers when they climb onto the operating platform by using guardrails, protective pipes, and guard bars in combination to prevent them from falling off the platform, thus improving worker safety and reducing potential safety hazards.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0036] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.
[0038] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0039] Please see the appendix Figures 1 to 7 As shown, this utility model provides a waste heat recovery device based on hydrogen electrothermal multi-energy coupling integrated energy, including a tank 1, a climbing ladder 2 fixedly installed on the outside of the tank 1, a head 3 installed on the top of the tank 1, an operating platform 4 fixedly installed on the outer wall of the head 3, the top of the climbing ladder 2 fixedly connected to the top of the operating platform 4, a guardrail 5 fixedly installed on the outside of the operating platform 4, a pressing limit component installed at the bottom of the top of the climbing ladder 2, and an anti-slip component fixedly installed at the middle position of the bottom of the pressing limit component.
[0040] The anti-slip assembly includes a blocking ring 14, a slowing roller 15, and a slowing eccentric roller 16. The blocking ring 14 is fixedly connected to the middle position of the bottom of the outer side of the pressing and limiting assembly. The slowing roller 15 is rotatably connected to the inside of the blocking ring 14 near the top position, and the slowing eccentric roller 16 is rotatably connected to the inside of the blocking ring 14 near the bottom position. In the integrated energy system based on hydrogen-electric-thermal multi-energy coupling, the waste heat recovery device integrates hydrogen energy, electrical energy, and thermal energy to achieve energy cascade utilization and efficiency improvement.
[0041] With the above structure, when cleaning the inside of tank 1 is required, one can climb to the operating platform 4 at the top of tank 1 via the climbing ladder 2. One end of the water pipe is then passed through the position between the slowing roller 15 and the slowing eccentric roller 16 inside the blocking ring 14. At this point, the outer side of the water pipe is in contact with the outer side of the slowing roller 15 and the slowing eccentric roller 16. After one end of the water pipe passes through the blocking ring 14, it can be connected to a high-pressure water gun. The end cap 3 is then opened, and the inside of tank 1 is flushed and cleaned using the high-pressure water gun. If the high-pressure water gun is placed improperly on the operating platform 4 and falls, because the water pipe connected to the high-pressure water gun passes through the blocking ring 14 and is located between the slowing roller 15 and the slowing eccentric roller 16, during the fall of the high-pressure water gun, the water pipe will experience [something] between the slowing roller 15 and the slowing eccentric roller 16. The water pipe slides and rotates due to friction. The slowing roller 15 and the slowing eccentric roller 16 then rotate. Due to the restraining effect of the slowing roller 15 and the slowing eccentric roller 16, and as the slowing eccentric roller 16 rotates, the distance between them gradually decreases, tightening the clamping of the water pipe. This further slows the movement speed of the water pipe when the high-pressure water gun falls. During this process, the water pipe remains inside the blocking ring 14 and does not fall completely with the high-pressure water gun. At this point, the worker can promptly pull the water pipe to stop the high-pressure water gun from falling and simultaneously pull it back onto the operating platform 4 through the water pipe, allowing the worker to continue working. This prevents the high-pressure water gun from falling directly to the ground and interrupting the cleaning work, and also avoids damage to the high-pressure water gun, thus ensuring the normal progress of the cleaning work and improving its efficiency.
[0042] In a preferred embodiment, please refer to Figure 2 and Figure 3Hinges 6 are symmetrically fixed on both sides of the top of the operating table 4 near the front. Hinges 6 are internally connected to hinge columns 11 with damping rotation. Protective tubes 7 are fixed on the outer walls of hinge columns 11. "U"-shaped protective rods 8 are inserted into the two protective tubes 7 and extend to the outside of the protective tubes 7. Baffles 18 are fixed inside the hinges 6. A through groove is opened at the middle of the bottom of the baffle 18. The width of the through groove is greater than the diameter of the protective tube 7 to prevent the bottom of the protective tube 7 from interfering with the bottom of the protective tube 7 during rotation. The back of the baffle 18 is in contact with the outer side of the vertically positioned protective tube 7.
[0043] In this embodiment, when a worker climbs onto the operating platform 4, the guardrail 5, the protective pipe 7, and the protective rod 8 work together to protect the worker, preventing the worker from falling off the operating platform 4 while working, thus improving the worker's safety and reducing safety hazards during work.
[0044] Secondly, please refer to again Figure 4 and Figure 5 The two ends of the protective rod 8 are slidably connected to the inside of the corresponding protective tube 7. A retaining screw 12 is threadedly connected at the position on the outside of the protective tube 7 corresponding to the protective rod 8. The end of the retaining screw 12 near the protective rod 8 extends into the inside of the protective tube 7.
[0045] In the above structure, when it is necessary to adjust the height of the protective rod 8 for better protection, the retaining screw 12 can be turned off to release its positioning effect on the protective rod 8. At this time, the protective rod 8 can be lifted upward, allowing both ends of the protective rod 8 to slide inside the protective tube 7. Simultaneously, the protective rod 8 moves upward. When the protective rod 8 slides to an appropriate height, the retaining screw 12 can be tightened again to reposition the protective rod 8. This achieves the height adjustment of the protective rod 8, making it suitable for workers of different heights, improving its protective capability, and further enhancing the safety of workers.
[0046] Secondly, please refer to the following as well. Figure 2 A storage slot 9 is provided on the top of the operating table 4 at a position corresponding to the protective tube 7 and the protective rod 8. The storage slot 9 is adapted to the protective tube 7 and the protective rod 8 at the corresponding positions.
[0047] After cleaning, the above structure allows for the tightening of the retaining screw 12 to insert the bottom end of the protective rod 8 into the interior of the protective tube 7. When the protective rod 8 is inserted to its maximum length inside the protective tube 7, the storage groove 9 matches the dimensions of the protective tube 7 and the protective rod 8. At this point, the pressing limit component can be adjusted. After the pressing limit component is adjusted, the protective tube 7 and the protective rod 8 are pushed to gradually rotate into the storage groove 9. The storage groove 9 stores the protective tube 7 and the protective rod 8, while also protecting them and extending their service life.
[0048] In a preferred embodiment, please refer to Figure 2 and Figure 6 The pressing and limiting assembly includes a limiting rod 10. The two ends of the limiting rod 10 are located at the bottom of both ends of the climbing ladder 2. The two ends of the limiting rod 10 penetrate the interior of the climbing ladder 2 and extend upward. The part of the limiting rod 10 that penetrates the climbing ladder 2 is slidably connected to the climbing ladder 2. A spring 17 is provided on the outer wall of this part of the climbing ladder 2. The top of the inner wall of the spring 17 is fixedly connected to the outer wall of the limiting rod 10, and the bottom of the outer side of the spring 17 is fixedly connected to the inner wall of the climbing ladder 2. A stop bar 19 is fixedly connected between the two protective tubes 7. When the protective tubes 7 and the protective rod 8 are in a vertical state, the limiting rod 10 is located on the back of the stop bar 19, and the outer side of the stop bar 19 is in contact with the outer side of the limiting rod 10.
[0049] In this embodiment, after the worker climbs onto the operating platform 4, they can push the protective rod 8 and protective tube 7 stored inside the storage slot 9, causing the protective tube 7 and protective rod 8 to gradually rotate vertically. During the pushing process, the protective tube 7 and protective rod 8 drive the hinge column 11 to rotate. When the rotation reaches the vertical position, the outer side of the protective tube 7 contacts the baffle 18. When the protective tube 7 is about to reach the vertical position, the worker can step vertically downwards on the middle position of the limiting rod 10, causing the pressing ring 13 to drive the limiting rod 10 downwards, thereby causing the limiting rod 10 to slide downwards inside the climbing ladder 2. At this time, the spring 17 is compressed. When the top of the limiting rod 10 slides below the stop bar 19, the worker can continue to rotate the protective tube 7 and protective rod 8 to the vertical position, with the stop bar 19 parallel to the top of the operating platform 4. At this point, the pressing ring 13 can be stopped. Due to the elastic force of the spring 17, the limiting rod 10 is reset. At this time, the top of the limiting rod 10 exceeds the height of the stop rod 19, and the outer side of the limiting rod 10 contacts the outer side of the stop rod 19, thereby completing the fixation of the protective tube 7 and the protective rod 8, making the protective tube 7 and the protective rod 8 more stable, thereby improving the protective capability of the protective rod 8, and thus improving the safety of the workers and reducing safety hazards. When it is necessary to store the protective tube 7 and the protective rod 8, the pressing ring 13 can be pressed again, causing the pressing ring 13 to drive the limiting rod 10 downward. The top of the limiting rod 10 gradually falls below the stop rod 19. At this time, the protective tube 7 and the protective rod 8 can be pushed to store the protective tube 7 and the protective rod 8 inside the storage groove 9.
[0050] Secondly, please refer to again Figure 2 and Figure 6 A semi-circular ring 13 is formed at the middle of the limiting rod 10. The pressing ring 13 is located on the front of the end cap 3. The blocking ring 14 is fixedly connected to the middle of the bottom outer side of the pressing ring 13.
[0051] With the above structure, when it is necessary to adjust the position of the limiting rod 10, the pressing ring 13 can be stepped down to move the limiting rod 10 downward, thereby adjusting the position of the limiting rod 10. At the same time, since the pressing ring 13 is a semi-circular ring structure, it prevents the climbing ladder 2 from obstructing the limiting rod 10 and the pressing ring 13 during the movement process.
[0052] In a preferred embodiment, please refer to Figure 7 Both the slowing roller 15 and the slowing eccentric roller 16 are connected to the inner wall of the blocking ring 14 for damped rotation.
[0053] In the above structure, when the high-pressure water gun falls from the operating platform 4, the water pipe located between the slowing roller 15 and the slowing eccentric roller 16 moves with the high-pressure water gun. At the same time, due to the action of friction, the slowing roller 15 and the slowing eccentric roller 16 rotate. Since the slowing roller 15 and the slowing eccentric roller 16 are connected to the blocking ring 14 with damping rotation, the rotation speed of the slowing roller 15 and the slowing eccentric roller 16 can be reduced, thereby slowing down the movement speed of the water pipe, thus slowing down the falling speed of the high-pressure water gun, making it easier for the staff to grab the moving water pipe, thereby reducing the probability of the high-pressure water gun falling from a height to the ground.
[0054] In a preferred embodiment, please refer to Figure 1 The bottom of tank 1 is fixedly equipped with four support legs.
[0055] With the above structure, when the device is in use, it can be supported on the ground by four support legs, making the device more stable.
[0056] In a preferred embodiment, please refer to Figure 2 Both the protective tube 7 and the protective rod 8 are made of aluminum alloy.
[0057] The above structure reduces the mass of the protective tube 7 and the protective rod 8 within the same volume, making it easier to adjust the position of the protective tube 7 and the protective rod 8.
[0058] In a preferred embodiment, please refer to Figure 1 The two ends of tank 1 are arc-shaped.
[0059] With the above structure, since both ends of the tank 1 are arc-shaped, when water is used to rinse the outside of the tank 1, the rinsing water will flow down along the arc-shaped structure, preventing the rinsing water from accumulating at the top of the tank 1 and causing corrosion at the top of the tank 1, thus improving the rinsing effect.
[0060] The working principle of this utility model is as follows: When cleaning the inside of tank 1 is required, one can climb to the operating platform 4 at the top of tank 1 using the climbing ladder 2. One end of the water pipe is then passed through the position between the slowing roller 15 and the slowing eccentric roller 16 inside the blocking ring 14. At this point, the outer side of the water pipe is in contact with the outer side of the slowing roller 15 and the slowing eccentric roller 16. After one end of the water pipe passes through the blocking ring 14, it can be connected to a high-pressure water gun. The end cap 3 is then opened, and the inside of tank 1 is flushed and cleaned using the high-pressure water gun. If the high-pressure water gun is placed improperly on the operating platform 4 and falls, it will be affected by the high-pressure water... The water supply pipe connected to the gun passes through the inside of the blocking ring 14 and is located between the slowing roller 15 and the slowing eccentric roller 16. Therefore, during the process of the high-pressure water gun falling, the water supply pipe slides between the slowing roller 15 and the slowing eccentric roller 16, and the slowing roller 15 and the slowing eccentric roller 16 rotate due to friction. At this time, due to the limiting effect of the slowing roller 15 and the slowing eccentric roller 16, the water supply pipe remains inside the blocking ring 14 and does not fall completely with the high-pressure water gun. At this time, the staff can pull the water supply pipe in time to stop the high-pressure water gun from falling, and at the same time pull the high-pressure water gun back to the operating table 4 through the water supply pipe so that the staff can continue to work.
[0061] After the operator climbs onto the operating platform 4, they can push the protective rod 8 and protective tube 7 stored inside the storage slot 9, causing the protective tube 7 and protective rod 8 to gradually rotate vertically. During this pushing process, the protective tube 7 and protective rod 8 drive the hinge column 11 to rotate. When rotated to a vertical position, the outer side of the protective tube 7 contacts the baffle 18. When the protective tube 7 is about to reach a vertical position, the operator can step vertically downwards on the pressing ring 13, causing the pressing ring 13 to drive the limiting rod 10 downwards, thereby causing the limiting rod 10 to slide downwards inside the climbing ladder 2. When the spring 17 is compressed, when the top of the limit rod 10 slides to below the stop rod 19, the protective tube 7 and the protective rod 8 can be rotated to a vertical position and the stop rod 19 is parallel to the top of the operating table 4. At this time, the pressing ring 13 can no longer be stepped on. Due to the elastic force of the spring 17, the limit rod 10 is reset. At this time, the top of the limit rod 10 exceeds the height of the stop rod 19, and the outer side of the limit rod 10 contacts the outer side of the stop rod 19, thereby completing the fixation of the position of the protective tube 7 and the protective rod 8, making the protective tube 7 and the protective rod 8 more stable.
[0062] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model shall be implemented according to conventional methods in the art unless otherwise specified or limited.
