Description

Technical Field

[0001] This invention relates to the field of mobile thermal storage technology, specifically to a mobile thermal storage device with good sealing performance. Background Technology

[0002] The mobile thermal storage device, equipped with vacuum insulation and multiple composite insulation designs, effectively prevents leakage of the thermal storage medium and heat loss. It boasts outstanding sealing reliability and heat-locking insulation performance, keeping heat loss during static storage and transportation to an extremely low level. The device is equipped with flexible mobile components, allowing for rapid relocation and deployment as needed. It is suitable for various scenarios such as industrial waste heat recovery, temporary heating, and outdoor heat energy replenishment. The overall structure is compact, pressure-resistant, and impact-resistant, combining efficient thermal storage, stable heat release, and safe portability. It can achieve efficient storage, safe transfer, and on-demand supply of thermal energy.

[0003] Chinese patent CN220398323U discloses a mobile phase change thermal storage device, including a mounting box. The top of the mounting box has a hinged door. A water inlet pipe is connected to the left side of the mounting box, and one end of the water inlet pipe is connected to a heat exchange pipe. A base plate is fixedly mounted on the bottom of the mounting box, and casters are fixedly mounted on the bottom of the base plate. Support mechanisms are evenly arranged on both sides of the base plate. This mobile phase change thermal storage device, with its support mechanisms and casters, facilitates the fixing and movement of the device. While this technical solution enables the movement of the thermal storage device, in actual outdoor operation, low-temperature rainwater directly washes over the tank surface during rainfall, creating forced convection heat dissipation. This leads to increased heat loss in the thermal storage device, a rapid drop in storage temperature, and a significant reduction in thermal energy storage efficiency. Furthermore, even small gaps in sealed areas such as tank flanges, quick-connect interfaces, and manholes allow rainwater to easily seep into the device. Additionally, the devices commonly use insulation materials such as rock wool, aerogel, and polyurethane, whose thermal conductivity increases dramatically after absorbing moisture, causing a substantial increase in heat loss and further weakening the device's insulation and thermal storage performance. This restricts the stable all-weather operation of the mobile thermal storage device. Summary of the Invention

[0006] This invention provides a mobile thermal energy storage device with good sealing performance. It has the following beneficial effects: 1. This mobile thermal storage device features excellent sealing. The unfolded tarpaulin provides complete rain protection for the storage tank during heat release operations, preventing rainwater from washing over the tank body, flanges, valves, and quick-connect fittings, thus preventing corrosion and aging of seals. This ensures the device's sealing performance from the source. When not in use, the tarpaulin is stored inside the outer shell, not interfering with the device's transport or heat release operations. It adapts to mobile usage needs, enabling uninterrupted heat release operations even in rainy weather, avoiding operational interruptions due to rainfall, and enhancing the mobile thermal storage device's all-weather outdoor operation capability. Furthermore, it provides shade during periods of high temperature and direct sunlight, reducing the outer shell temperature and further minimizing heat loss.

[0007] 2. This mobile thermal storage device with good sealing performance uses a slider-driven connecting frame to simultaneously unfold the rain cover and move the cleaning roller to remove dust, sludge, and other deposits from the tank wall in real time, preventing long-term adhesion and corrosion of the tank body. At the same time, it keeps the area around the sealing interface clean. The cleaning roller is made of flexible material and has a buffer structure, which can not only prevent hard scraping from causing scratches on the tank wall and damage to the paint, but also buffer the impact of impurities, prevent the cleaning roller from jamming and the mechanism from getting stuck, and ensure smooth and reliable operation.

[0008] 3. This mobile heat storage device with good sealing performance adopts an arc-shaped flow guide and a through-type inclined material drop trough, which guides the scraped impurities into the guide trough and discharges them in a concentrated manner, avoiding the accumulation, adhesion and blockage of impurities and channels, removing dust, mud and other attachments on the tank wall, and reducing the corrosion and pollution of impurities on the tank body and surrounding sealing interfaces.

[0009] 4. This mobile thermal storage device with good sealing performance relies on the impact of rainwater to automatically flush out impurities, preventing impurities from accumulating and clogging in the guide groove, and also preventing dust and impurities from adhering to the inner wall of the guide and causing the flow channel to narrow, thus ensuring the long-term smooth flow of the guide and impurity discharge system.

[0010] 5. This mobile thermal storage device with good sealing performance directly uses natural rainwater as a flushing medium to achieve fully automatic cleaning of the guide channel. Combining the hydraulic flushing of rainwater with the scraping action of the scraper frame, it removes impurities in the channel, avoiding the problems of impurity accumulation and channel blockage, and eliminating the need for regular manual cleaning and maintenance.

[0013] Please see Figures 1-2 The present invention provides a mobile heat storage device with good sealing effect, including a mobile chassis 1. The mobile chassis 1 is used for site transportation. After arriving at the heat use site, the sealing port 3 is reliably connected to the heat use equipment to provide continuous and stable energy supply to the target equipment and the heat supply area. The top of the mobile chassis 1 is fixedly connected to the heat storage tank 2. The heat storage tank 2 adopts a multi-layer composite sealing structure, equipped with a vacuum insulation layer and end face sealing components, so that the sealed cavity maintains a stable sealing and heat insulation state for a long time, suppresses heat radiation and heat conduction loss, achieves long-term constant temperature heat storage, and ensures heat energy storage efficiency. A sealing port 3 is fixedly connected to the middle of the top of the heat storage tank 2. The device is connected to the heat source system through the special sealing port 3. The heat storage medium is added and heated in a fully enclosed circulation loop. After the medium has completed the heat energy storage, the valve of the sealing port 3 is quickly closed to construct a completely sealed heat storage cavity. A shielding component 4 is fixedly connected to the side of the heat storage tank 2. A baffle 5 is fixedly connected to the side of the shielding component 4. The bottom of the baffle 5 is fixedly connected to the top of the two sliding frames 47 on the side away from the housing 48. After the heat release is completed, the device can be reconnected to the heat source to complete the cycle heat charging operation. When carrying out heat release operation in rainy weather, the shielding component 4 can be activated to protect the heat storage tank 2 body, prevent rainwater from corroding the equipment, and ensure the safe and stable operation of the heat release operation. Example 1, please refer to Figures 3-4The invention also includes a shielding component 4, both ends of the lead screw 41 are rotatably connected to the inner side of the movable chassis 1, the driving component 42 is fixedly connected to the side of the movable chassis 1, and the output end of the driving component 42 is fixedly connected to one end of the lead screw 41. In the case of continuous rain in rainy weather, the driving component 42 is activated, and the output end of the driving component 42 drives the lead screw 41 to rotate in the inner side of the movable chassis 1. The bottom of the slider 43 is slidably connected to the inner side of the movable chassis 1, the inner side of the slider 43 is threadedly connected to the side of the lead screw 41, and sliding frames 47 are fixedly connected to both sides of the slider 43. The inner side of the sliding frame 47 is slidably connected to the side of the guide shaft 45, and the side of the sliding frame 47 is slidably connected to the inner side of the guide frame 44. The slider 43 is driven to move linearly through the lead screw 41, thereby driving the two sliding frames 47 to move synchronously within the guide frame 44. The sliding frame 47 and the guide shaft 45 on the inner side of the guide frame 44 form a sliding guide engagement. A storage shell 48 is fixedly connected to the top of the guide frame 44. A folded rain cover 46 is provided on the inner side of the storage shell 48. A connecting mechanism 49 is fixedly connected between the tops of the two sliding frames 47. The two sets of sliding frames 47 pull the folded rain cover 46 out of the storage shell 48 through the connecting mechanism 49 and continue to move towards the blocking frame 5 until it is in contact with the inner side of the blocking frame 5 and is limited, thus completing the fully automatic unfolding of the rain cover. The unfolded rain cover can provide complete rain protection for the heat storage tank 2 that is releasing heat, preventing rainwater erosion from causing a decrease in the sealing performance of the device, and achieving full rain protection for the sealing parts of the tank. Please see Figure 5 It also includes a connecting mechanism 49. The bottom sides of the connecting frame 491 are fixedly connected to the top of the two sliding frames 47. The side of the connecting frame 491 is fixedly connected to the side of the folded rain cover 46 away from the storage shell 48. During the movement of the slider 43, the connecting frame 491 is synchronously pulled to move horizontally by the two sliding frames 47. The connecting frame 491 drives the folded rain cover 46 to unfold smoothly, forming a full-coverage rain protection for the heat storage tank 2. Cleaning components 494 are symmetrically arranged on both sides of the connecting frame 491. A contact component 495 is fixedly connected to the side of the connecting frame 491 away from the cleaning components 494. At the same time, the connecting frame 491 drives the cleaning components 494 on both sides to move synchronously, so that the cleaning components 494 fit against the outer wall of the heat storage tank 2, and complete the automated cleaning operation of the outer surface of the tank. The impurities scraped off are guided into the contact component 495 and discharged in a concentrated manner. A water guide groove 492 is provided through the inner side of the connecting frame 491, and a water inlet hole 493 is provided around the top of the connecting frame 491. Under continuous rainfall conditions, rainwater flows into the built-in water guide groove 492 through the water inlet hole 493 evenly distributed on the top of the connecting frame 491, forming a directional water flow to automatically flush the contact component 495, thereby rinsing and cleaning the collected impurities and preventing impurities from accumulating and clogging. Please see Figures 6-7 It also includes a cleaning component 494. The side of the cleaning housing 4941 is fixedly connected to the connecting frame 491. During the translation of the slider 43, the connecting frame 491 is driven to move synchronously through the sliding frames 47 on both sides. While the connecting frame 491 pulls the folded rain cover 46 to unfold and cover the rain, it drives the cleaning housings 4941 on both sides to move synchronously along the side wall of the heat storage tank 2. A cleaning plate 4942 is slidably connected to the inner side of the connecting frame 491. The cleaning plate 4942 is in contact with the side of the heat storage tank 2. A support frame 4946 is fixedly connected to the inner side of the cleaning plate 4942. A cleaning roller 4947 is fixedly connected to the support frame 4946. The cleaning shell 4941 drives the cleaning roller 4947 to move against the tank wall through the support frame 4946 inside the cleaning plate 4942, so as to achieve contact cleaning of dust and impurities on the surface of the heat storage tank 2. Both sides of the cleaning plate 4942 are fixedly connected to slide rods 4943. The other end of the slide rods 4943 is slidably connected to the inner side of the cleaning shell 4941. A second spring 4944 is sleeved on the slide rods 4943. One end of the second spring 4944 is fixedly connected to the cleaning plate 4942, and the other end of the second spring 4944 is fixedly connected to the inner side of the cleaning shell 4941. When the cleaning roller 4947 squeezes the impurities on the tank wall, the reaction force can drive the cleaning plate 4942 to adaptively slide and adjust inside the cleaning shell 4941 through the slide rods 4943, and simultaneously compress the second spring 4944 sleeved on the outside of the slide rods 4943. This achieves flexible cleaning work between the cleaning roller 4947 and the tank wall. The cleaning roller 4947 is made of flexible material to avoid scratching the tank wall and to prevent the cleaning roller 4947 from getting stuck with the impurities during cleaning. The debris that has fallen off is guided by the arc-shaped structure inside the cleaning plate 4942 and falls into the through-type discharge chute 4945; The sides of the cleaning shell 4941 and the cleaning plate 4942 are provided with a material discharge groove 4945. The material discharge groove 4945 and the guide groove 4951 are the same size. The material discharge groove 4945 passes through the cleaning plate 4942 and the cleaning shell 4941. It adopts a sloping flow guide design to guide impurities into the guide groove 4951 and discharge them in a concentrated manner, so as to avoid the accumulation and blockage of scraped impurities. Please see Figure 8 It also includes a contact component 495, and a guide groove 4951 is opened on both sides of the connecting frame 491. The guide groove 4951 is connected to the water guide groove 492. Under continuous rainfall conditions, rainwater flows into the water guide groove 492 through the water inlet hole 493 at the top of the connecting frame 491, forming a directional water flow to automatically flush the inside of the guide groove 4951, preventing the impurities scraped off by the cleaning roller 4947 from accumulating and clogging after entering the guide groove 4951 through the material drop chute 4945. The top of bracket 4952 is fixedly connected to the inner side of guide groove 4951. A telescopic rod 4953 is fixedly connected to the side of bracket 4952. A bracket 4954 is fixedly connected to the other end of telescopic rod 4953. Scraper frame 4955 is fixedly connected to both ends of bracket 4954. As the rainfall continues, the amount of water flowing into the water channel 492 through the inlet hole 493 gradually increases. The scouring and impact force formed by the rainwater in the water channel 492 drives the scraper frame 4955 to slide along the guide groove 4951. The side of the scraper frame 4955 is slidably connected to the inner side of the guide groove 4951. A first spring 4956 is sleeved on the telescopic rod 4953 in the middle. One end of the first spring 4956 is fixedly connected to the first bracket 4952, and the other end of the first spring 4956 is fixedly connected to the second bracket 4954. The scraper frame 4955 drives the telescopic rod 4953 to extend and retract through the second bracket 4954, and simultaneously stretches the first spring 4956 sleeved on the telescopic rod 4953, so that the scraper frame 4955 slides against the inner wall of the guide groove 4951 to remove the deposited impurities in the groove. Specific workflow: The device connects to the heat source system through a dedicated sealing port 3, and completes the injection and heating of the heat storage medium in a fully enclosed circulation loop. After the medium has completed the thermal energy storage, quickly close the sealing port 3 valve to construct a completely sealed thermal storage cavity; The thermal storage tank 2 adopts a multi-layer composite sealing structure, equipped with a vacuum insulation layer and end face sealing components, so that the sealed cavity maintains a stable sealing and heat insulation state for a long time, suppresses heat radiation and heat conduction loss, achieves long-term constant temperature thermal storage, and ensures thermal energy storage efficiency. Equipped with a mobile chassis 1, the equipment is transported to the site. After arriving at the heating site, the sealing port 3 is reliably connected to the heating equipment. The controllable sealing regulating valve is slowly opened, and the high-temperature heat storage medium releases heat stably in the sealed circuit, providing continuous and stable energy to the target equipment and the heating area. There is no leakage of medium or no ineffective heat loss throughout the process. After the heat release is completed, the device can be reconnected to the heat source to complete the cycle of heat charging. When carrying out heat release operations in rainy weather, the shielding component 4 can be activated to protect the heat storage tank 2, preventing rainwater from corroding the equipment and ensuring the safe and stable operation of the heat release. In rainy weather with continuous rainfall, the drive unit 42 is activated, and the output end of the drive unit 42 drives the lead screw 41 to rotate inside the movable chassis 1. The slider 43 is driven to move linearly by the lead screw 41, which in turn drives the sliding frames 47 on both sides to move synchronously within the guide frame 44. The sliding frame 47 and the guide shaft 45 on the inner side of the guide frame 44 form a sliding guide engagement. Two sets of sliding frames 47 pull the folded rain cover 46 out of the storage shell 48 through the connecting mechanism 49 and continue to move towards the blocking frame 5 until it is in contact with the inner side of the blocking frame 5 and the rain cover is fully automatically unfolded. The unfolded rain cover can provide complete rain protection for the heat storage tank 2 that is releasing heat, preventing rainwater erosion from causing a decrease in the sealing performance of the device, and achieving full rain protection for the sealing parts of the tank. During the movement of slider 43, the connecting frame 491 is moved horizontally by the synchronous traction of the sliding frames 47 on both sides. The connecting frame 491 drives the folded rainproof cloth 46 to unfold smoothly, forming a full-coverage rainproof protection for the heat storage tank 2. At the same time, the connecting frame 491 drives the cleaning components 494 on both sides to move synchronously, so that the cleaning components 494 fit against the outer wall of the heat storage tank 2, completing the automated cleaning operation of the outer surface of the tank. The debris scraped off is guided into the contact component 495 and discharged in a concentrated manner. Under continuous rainfall conditions, rainwater flows into the built-in water guide channel 492 through the water inlet holes 493 evenly distributed on the top of the connecting frame 491, forming a directional water flow to automatically flush the contact component 495, thereby rinsing and cleaning the collected impurities and preventing impurities from accumulating and clogging. During the translation of slider 43, the connecting frame 491 is driven to move synchronously by the sliding frames 47 on both sides. While the connecting frame 491 pulls the folded rain cover 46 to unfold and cover the rain, it drives the cleaning shell 4941 on both sides to move synchronously along the side wall of the heat storage tank 2. The cleaning shell 4941 drives the cleaning roller 4947 to move against the tank wall through the support frame 4946 inside the cleaning plate 4942, thereby achieving contact cleaning of dust and impurities on the surface of the heat storage tank 2. When the cleaning roller 4947 squeezes against the impurities on the tank wall, the reaction force can drive the cleaning plate 4942 to adaptively slide and adjust inside the cleaning shell 4941 through the slide rod 4943, and simultaneously compress the second spring 4944 fitted on the outside of the slide rod 4943. This achieves flexible cleaning between the cleaning roller 4947 and the tank wall. The cleaning roller 4947 is made of flexible material to avoid scratching the tank wall and to prevent the cleaning roller 4947 from getting stuck with the impurities during cleaning. The debris that has fallen off is guided by the arc-shaped structure inside the cleaning plate 4942 and falls into the through-type discharge chute 4945; The material discharge chute 4945 passes through the cleaning plate 4942 and the cleaning shell 4941, and adopts a sloping flow guide design to guide impurities into the guide chute 4951 and discharge them in a concentrated manner, so as to avoid the accumulation and blockage of scraped impurities. Under continuous rainfall conditions, rainwater flows into the water guide trough 492 through the water inlet 493 at the top of the connecting frame 491, forming a directional water flow to automatically flush the inside of the guide trough 4951, preventing the impurities scraped off by the cleaning roller 4947 from accumulating and clogging after entering the guide trough 4951 through the material drop trough 4945. As the rainfall continues, the amount of water flowing into the water channel 492 through the inlet hole 493 gradually increases. The scouring and impact force generated by the rainwater in the water channel 492 drives the scraper frame 4955 to slide along the guide channel 4951. The scraper frame 4955 drives the telescopic rod 4953 to extend and retract through the bracket 2 4954, and simultaneously stretches the first spring 4956 sleeved on the telescopic rod 4953, so that the scraper frame 4955 slides against the inner wall of the guide groove 4951 to remove the deposited impurities in the groove.
