[0002] A medium- and high-temperature phase-change heat storage device is a device that uses phase-change materials to store and release heat. The existing phase-change heat storage device includes an outer shell, an inner tank and a coil. The inner tank is filled with phase-change materials, and the coil is buried in the phase-change materials. Hot water or cold water enters the coil through a water inlet pipe to exchange heat with the phase-change materials filled in the inner tank.

[0083] The first reset mechanism is disposed on the side wall of the fixed box 14 , and the first moving block 201 is connected to the first reset mechanism. The first reset mechanism is used to move and reset the first moving block 201 .

[0089] The second pushing mechanism is disposed above the fixed box 14 and is used to push the U-shaped plate 203 to move.

[0090] The detection component is arranged above the fixed box 14 and is used to detect the distance of the U-shaped plate 203. When in use, the first solenoid valve 18 and the second solenoid valve 21 are opened, and water is supplied through the first solenoid valve 18. The liquid enters the fixed box 14 through the first L-shaped tube 17, and then enters the coil 104 through the first telescopic tube 16 and the water inlet pipe 105 for heat exchange. The liquid after heat exchange passes through the water outlet pipe 106, the second telescopic tube 19 and the second L-shaped tube 20 and is discharged through the second solenoid valve 21. At the same time, when the liquid enters the fixed box 14, it impacts the surface of the baffle 208, which can drive the rotating shaft 204 and the rotating disk 205 to rotate, and through the first telescopic tube 16 and the water inlet pipe 105, the liquid enters the coil 104 for heat exchange. The contraction mechanism drives the conical column 206 and the ball 207 to rotate, so that the conical column 206 can reciprocate and abut against the two opposite side walls of the U-shaped plate 203. When the conical column 206 abuts against the side wall of the U-shaped plate 203, the U-shaped plate 203 can be pushed to move, and the ball 207 can also roll along the side wall of the U-shaped plate 203. When the conical column 206 passes over the side wall of the U-shaped plate 203, the U-shaped plate 203 can be reset under the action of the second reset mechanism. In this way, the U-shaped plate 203 can drive the moving plate 13 to reciprocate. At the same time, the rubber sleeve 12 is deformed. At the same time, the coil 104 is driven to reciprocate in the horizontal direction through the water inlet pipe 105.

[0099] The rotating mechanism is arranged on the side wall of the fourth moving block 304, and a pointer 908 is rotatably connected to the rotating mechanism. The rotating mechanism is used to rotate the pointer 908. When it is necessary to detect the sealing of the coil 104, the coil 104 can be filled with liquid, then the first solenoid valve 18 and the second solenoid valve 21 are closed, and then the third moving block 303 is driven downward by the second moving module 302. Under the action of the second telescopic mechanism, the piston 305 is driven to squeeze and pressurize the liquid in the coil 104. At the same time, the pointer 908 can be rotated by the rotating mechanism. The scale on the arc-shaped dial 907 indicated by the pointer 908 is detected by the visual sensor 905 to determine the pressure of the liquid in the coil 104. Whether the scale on the arc-shaped dial 907 indicated by the pointer 908 changes can be observed by the visual sensor 905 to determine whether the coil 104 is leaking, thereby facilitating the detection of the leakage of the coil 104, being safer and more reliable, and ensuring the effect of its use.

At the same time, the fourth elastic member 903 is gradually compressed.

[0127] Working principle: When in use, the first solenoid valve 18 and the second solenoid valve 21 are opened, water is supplied through the first solenoid valve 18, and the liquid enters the fixed box 14 through the first L-shaped tube 17, and then enters the coil 104 through the first telescopic tube 16 and the water inlet pipe 105 for heat exchange. The liquid after heat exchange passes through the outlet pipe 106, the second telescopic tube 19 and the second L-shaped tube 20 and is discharged through the second solenoid valve 21. At the same time, when the liquid enters the fixed box 14, it impacts the surface of the baffle 208, which can drive the rotating shaft 204 and the rotating disk 205 to rotate, and drives the conical column 206 and the ball 207 to rotate through the first telescopic mechanism, so that the conical column 206 can reciprocate with the two opposite side walls of the U-shaped plate 203. When the conical column 206 abuts against the side wall of the U-shaped plate 203, the U-shaped plate 203 can be pushed to move. At the same time, the second elastic member 503 is deformed, and the ball 207 can also roll along the side wall of the U-shaped plate 203. When the conical column 206 passes over the side wall of the U-shaped plate 203, the U-shaped plate 203 can move and reset under the action of the second elastic member 503. In this way, the U-shaped plate 203 can drive the moving plate 13 to move back and forth. At the same time, the rubber sleeve 12 is deformed. At the same time, the coil 104 is driven to move back and forth in the horizontal direction through the water inlet pipe 105. When the phase change material is in solid state, when the conical column 206 abuts against the side wall of the U-shaped plate 203, the third elastic member 803 can be compressed to avoid getting stuck.

[0128] At the same time, when the U-shaped plate 203 moves, it can drive the push rod 601 to move. When the push rod 601 slides on the triangular block 603, it can push the U-shaped plate 203 to move upward. At the same time, the first elastic member 404 is stretched. When the push rod 601 passes over the triangular block 603, the U-shaped plate 203 can move downward and reset under the action of the first elastic member 404. This reciprocating process can drive the movable plate 13 to move back and forth in the vertical direction. At the same time, the rubber sleeve 12 is deformed. At the same time, the coil 104 is driven to move back and forth in the vertical direction through the water inlet pipe 105.

[0129] When the U-shaped plate 203 moves a large distance, it can be detected by the proximity switch 702, indicating that the phase change material gradually turns into liquid. At this time, the second moving block 202 can be reciprocated by the first moving module 209. At the same time, the U-shaped plate 203 can be driven to reciprocate by the second reset mechanism, and then the coil 104 is driven to reciprocate by the moving plate 13 and the water inlet pipe 105. At the same time, the rubber sleeve 12 is deformed, so that during heat exchange, the coil 104 can be reciprocated in the XYZ directions, which can improve the efficiency and effect of heat exchange, thereby improving the efficiency and effect of heat storage.

[0130] When the sealing of the coil 104 needs to be tested, the coil 104 can be filled with liquid, then the first solenoid valve 18 and the second solenoid valve 21 are closed, and then the third moving block 303 is driven to move downward by the second moving module 302. At this time, the fourth elastic member 903 can be gradually compressed, so that the piston 305 can be driven by the fourth moving block 304 to squeeze and pressurize the liquid in the coil 104. At the same time, the fourth elastic member 903 is gradually compressed. When the third moving block 303 continues to move downward, the cleaning block 307 can be driven to move downward through the connecting plate 306, so that the lens of the visual sensor 905 can be automatically cleaned to ensure the accuracy of its detection.

[0131] When the block to be cleaned 307 moves to the bottom of the visual sensor 905, when the third moving block 303 continues to move downward, the fourth elastic member 903 is continuously compressed. At this time, the liquid in the coil 104 can be continuously pressurized. Moreover, when the third moving block 303 moves downward, the push pin 1005 can be driven to slide in the slide groove 1003 through the connecting block 1004, thereby pushing the pointer 908 to rotate upward along the rotating pin 1002. In addition, the arc indicated by the pointer 908 is engraved by the visual sensor 905. By detecting the scale on the dial 907, the pressure of the liquid in the coil 104 can be determined. When the required pressure is reached, the second movable module 302 is stopped so that the third movable block 303 no longer moves downward. At this time, the pressure maintaining operation is performed, and by observing through the visual sensor 905 whether the scale on the arc-shaped dial 907 indicated by the pointer 908 changes, it can be determined whether the coil 104 is leaking, thereby facilitating the detection of the leakage of the coil 104, being safer and more reliable, and ensuring the effect of its use.
