The downward movement of the lifting platform causes the object to be tested to fall onto the placement table, and then the lifting platform continues to move downward and no longer contacts the object to be tested, so that the lower surface of the object to be tested can contact the heat flow, thereby avoiding the slow heating speed of the lower surface of the object to be tested. In addition, when the object to be tested is lifted by the lifting platform, the lifting of the object to be tested also disturbs the heat flow in the insulation mechanism, thereby making the temperature distribution in the insulation mechanism uniform. At the same time, the piston component introduces external air into the insulation mechanism, so that the pressure in the insulation mechanism increases, thereby improving the temperature conduction speed.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0037] Furthermore, the terms “first”, “second”, and “third” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements.

[0039] For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Examples, such as Figure 1-Figure 6As shown, a phase change energy storage component heat storage performance test box includes a heat preservation mechanism 100 and a heating mechanism 200 for heating the heat preservation mechanism 100, and the heat preservation mechanism 100 is connected with a disturbance mechanism 300 and a pressurizing mechanism 400; the disturbance mechanism 300 includes a placement table 310 and a lifting platform 320 vertically penetrating and sliding in the middle of the placement table 310, and the object to be detected is placed on the placement table 310, and a thermometer for measuring the object to be detected is also provided in the heat preservation mechanism 100; the pressurizing mechanism 400 includes a piston component, and when the placement table 310 slides vertically on the lifting platform 320, the piston component introduces external air into the heat preservation mechanism 100.

[0041] The working mechanism of the heat storage performance detection box provided in this embodiment is as follows:

[0042] When testing the performance of the phase change energy storage material, the phase change energy storage material is placed in the heat preservation mechanism 100 so that the object to be tested is on the placement table 310, and the heating mechanism 200 is started to heat the inside of the heat preservation mechanism 100 so that the object to be tested is heated. During the heating process, the lifting platform 320 slides vertically back and forth in the middle of the placement table 310. The upward movement of the lifting platform 320 lifts the object to be tested so that the object to be tested is no longer in contact with the placement table 310. The downward movement of the lifting platform 320 causes the object to be tested to fall onto the placement table 310. The rear lifting platform 320 continues to move downward and no longer contacts the object to be detected, so that the lower surface of the object to be detected can contact the heat flow, thereby preventing the lower surface of the object to be detected from being heated slowly. In addition, when the object to be detected is lifted by the lifting platform 320, the lifting of the object to be detected disturbs the heat flow in the heat preservation mechanism 100, thereby making the temperature distribution in the heat preservation mechanism 100 uniform. At the same time, the piston component introduces external air into the heat preservation mechanism 100, thereby increasing the pressure in the heat preservation mechanism 100 and improving the temperature conduction speed.

[0043] The heat preservation mechanism 100 is provided with a pressure valve to prevent the piston component from applying excessive air pressure to the heat preservation mechanism 100;

[0044] After the object to be detected rises to the required temperature, the operation of the heating mechanism 200 is stopped, and the thermometer is turned on to monitor the temperature of the object to be detected, and the time required for the object to be detected to drop to the lowest temperature is detected, thereby obtaining the heat storage performance of the phase change energy storage component.

[0045] Among the optional methods of this embodiment, the more preferred ones are:

[0046] The four corners of the lower surface of the lifting platform 320 are connected with rectangular telescopic rods 330 , and the rectangular telescopic rods 330 are connected to the heat preservation mechanism 100 .

[0047] The arrangement of the four rectangular telescopic rods 330 limits the vertical lifting travel of the lifting platform 320 and enables the lifting platform 320 to slide vertically only, thereby ensuring that the lifting platform 320 can pass through the middle of the placement platform 310 and be lifted and lowered.

[0048] Among the optional methods of this embodiment, the more preferred ones are:

[0049] The disturbance mechanism 300 further includes a turntable 350 that rotates on a fixed axis in the heat preservation mechanism 100 . A connecting rod 360 is hinged on the end surface of the turntable 350 . One end of the connecting rod 360 away from the turntable 350 is hinged on the lower surface of the placement table 310 .

[0050] The hinged part between the connecting rod 360 and the turntable 350 deviates from the center of the turntable 350. When the turntable 350 rotates, the hinged point between the connecting rod 360 and the turntable 350 can revolve around the center of the turntable 350, and the top end of the connecting rod 360 is hinged to the lower surface of the placement table 310, so that when the turntable 350 rotates, it can drive the placement table 310 to move back and forth.

[0051] Among the optional methods of this embodiment, the more preferred ones are:

[0052] A slider 370 is slidably connected to the end surface of the rotating disk 350 , and the connecting rod 360 is hinged to the slider 370 . A screw rod 380 is rotatably connected to the rotating disk 350 , and a threaded hole matching with the screw rod 380 is provided on the slider 370 .

[0053] The screw rod 380 rotates on a fixed axis in the turntable 350 . When the screw rod 380 rotates, it can drive the slider 370 to slide radially on the turntable 350 , so that the hinged position between the connecting rod 360 and the slider 370 is changed, thereby adjusting the lifting stroke of the lifting platform 320 .

[0054] Among the optional methods of this embodiment, the more preferred ones are:

[0055] A rotating telescopic shaft 390 is connected inside the heat preservation mechanism 100, and a hexagon socket 391 is connected to the end of the rotating telescopic shaft 390. A socket that cooperates with the hexagon socket 391 is opened at the end of the screw 380. A pressure sensor is arranged on the placement table 310, and the object to be detected applies pressure to the pressure sensor. When the pressure level of the pressure sensor increases, the rotating telescopic shaft 390 is reversed to make the slider 370 close to the center of the turntable 350.

[0056] The rotating telescopic shaft 390 is extended and retracted by an electric telescopic rod and is driven to rotate by an external motor. The turntable 350 is set by a counterweight so that when it is in a stationary state, the end socket of the screw 380 is opposite to the inner hexagon 391, and when the two are opposite, the rotating telescopic shaft 390 is extended, so that the inner hexagon 391 is inserted into the end socket of the screw 380. Then the object to be detected is placed on the placement table 310, and the object to be detected applies pressure to the pressure sensor of the placement table 310. When the pressure sensor detects that the weight of the object to be detected is large, the rotating telescopic shaft 390 rotates to make the screw 380 rotate, and the screw 380 drives the slider 370 to slide toward the middle of the turntable 350, so that the force applied by the turntable 350 to the connecting rod 360 increases, but the stroke is reduced, thereby ensuring that the moving stroke of the heavy object to be detected is reduced, thereby reducing the load of the drive motor 341, and the rotating telescopic shaft 390 is shortened to make the inner hexagon 391 withdraw from the screw 380, and then the drive motor 341 can start to rotate.

[0057] Among the optional methods of this embodiment, the more preferred ones are:

[0058] The outside of the heat preservation mechanism 100 is connected to a driving motor 341 , an output end of the driving motor 341 is connected to a driving shaft 340 , and the turntable 350 is coaxially connected to the driving shaft 340 .

[0059] The driving shaft 340 penetrates the heat preservation mechanism 100 , and when the driving motor 341 is started, it drives the driving shaft 340 to rotate, so that the driving shaft 340 drives the rotating disk 350 to rotate.

[0060] Regarding the structure of the heat preservation mechanism 100, specifically:

[0061] The heat preservation mechanism 100 includes a heat preservation box 110, on which a U-shaped frame 120 is hinged. A threaded rod 140 is threadedly connected to the middle of the U-shaped frame 120, and the end of the threaded rod 140 is rotatably connected to a box door 130. A sealing strip is provided at the edge of the box door 130.

[0062] Rotating the threaded rod 140 can make the box door 130 move closer to or away from the insulation box 110, so that the insulation box 110 is sealed. When the box door 130 is completely separated from the insulation box 110, the U-shaped frame 120 can be manually controlled to swing to open the insulation box 110, so that the objects to be tested can be taken in and placed.

[0063] Among the optional methods of this embodiment, the more preferred ones are:

[0064] The heating mechanism 200 includes a circulation pipe 210 . Both ends of the circulation pipe 210 are connected to the heat preservation box 110 . A hot air blower 220 is connected to the middle of the circulation pipe 210 .

[0065] Both ends of the circulation pipe 210 are connected to the insulation box 110. The hot air blower 220 has a sealed shell, and blades and heating wires are arranged inside. The rotation of the blades causes the air in the insulation box 110 to circulate, and the heating wire heats the circulating air. In addition, the insulation box 110 is sealed, so that the hot air circulates in the insulation box 110 and is continuously heated, so that the heating speed of the insulation box 110 is accelerated.

[0066] Among the optional methods of this embodiment, the more preferred ones are:

[0067] The pressurizing mechanism 400 also includes a wobble plate 410, which is connected to the drive shaft 340. The piston component includes a piston cylinder 420 and a piston rod 421 sliding in the piston cylinder 420. A spring 422 is connected between the piston rod 421 and the piston cylinder 420, and the end of the piston rod 421 abuts against the end surface of the wobble plate 410. An exhaust pipe 430 and an exhaust pipe 440 are connected to the piston cylinder 420. Both the exhaust pipe 430 and the exhaust pipe 440 are provided with a one-way valve. The exhaust pipe 440 is located in the insulation box 110, and the exhaust pipe 430 is connected to the internal space of the hot air blower 220.

[0068] The setting of the pressurizing mechanism 400 increases the air pressure in the thermal insulation box 110, intensifies the collision between gas molecules, and thus further increases the heating rate. When the driving shaft 340 rotates, it drives the swing plate 410 to swing synchronously. At this time, the swing plate 410 continues to push the piston rod 421, and cooperates with the pushing effect of the spring 422 to make the piston rod 421 slide back and forth in the piston cylinder 420, so that the piston cylinder 420 draws external air and then sends the drawn air into the thermal insulation box 110.

[0069] Among the optional methods of this embodiment, the more preferred ones are:

[0070] The housing of the hot air blower 220 is connected to an air inlet pipe 450 , and a one-way valve is provided on the air inlet pipe 450 .

[0071] The exhaust pipe 430 of the piston cylinder 420 is connected to the outer shell of the hot air blower 220. The outer shell of the hot air blower 220 is also provided with an air inlet pipe 450. The air inlet pipe 450 has a one-way valve, so that external air can only enter the outer shell of the hot air blower 220 through the air inlet pipe 450. The piston cylinder 420 draws the hot air in the hot air blower 220 into the insulation box 110. The external air enters the outer shell of the hot air blower 220 and is heated by the heating wire in the hot air blower 220, so that the air pressurized for the insulation box 110 is hot air.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
