Description

Technical Field

[0001] The present invention belongs to the technical field of temperature detection of cold storage agents, and specifically relates to a temperature detection device and a detection method for storing a polymer phase change cold storage agent. Background Art

[0002] The polymer phase change cold storage agent is a new type of cold storage agent that combines a polymer material with water. It stores cold energy in the cold storage agent by using various physical, chemical, mechanical and other effective means, and releases the stored cold energy when needed. It can absorb and store a large amount of cold energy at low temperatures, and release a large amount of cold energy at higher temperatures, maintaining a low-temperature environment for itself and the surrounding small area for a long time. The polymer phase change cold storage agent needs to be equipped with a temperature detection device during storage to detect the real-time state of the polymer phase change cold storage agent.

[0003] In the prior art, a Chinese patent discloses a measuring device for measuring the temperature of a refrigerant in an air-conditioning system (Publication No.: CN218765666U). Its main structure includes a base arranged on an air-conditioning pipeline, a nest is provided on the base, and a detection sensor is arranged in the nest; the detection sensor is a thermocouple sensor; the nest includes a sleeve body, and the sleeve body is connected to the base by a thread; an installation hole is provided on the air-conditioning pipeline; the base is connected to the air-conditioning pipeline through the installation hole; a sealing ring is provided between the base and the installation hole; the sleeve body includes a lower sleeve body and an upper sleeve body, and the outer diameter of the upper sleeve body is larger than that of the lower sleeve body; an external thread is provided on the outer side of the lower sleeve body; the base includes a base body, and a connection hole is provided on the base body; an internal thread is provided in the connection hole; the lower sleeve body is connected to the connection hole by a thread; the base and the installation hole are connected by an interference fit.

[0004] In actual use, through the settings of the base, the nest and the detection sensor, the above patent can achieve real-time and accurate acquisition of the refrigerant temperature inside the pipeline, and at the same time measure it in direct contact with the refrigerant, so as to stably and reliably ensure the accuracy of the refrigerant temperature measurement. However, there are still corresponding drawbacks in actual use: when the above patent is used, a sealing ring is provided between the base and the installation hole, and a sealing ring is also provided between the nest and the base, so as to play a sealing role from the outside of the pipeline to prevent the cold storage agent in the pipeline from leaking outwards. However, the pressure generated by the cold storage agent stored in the pipeline will act on the sealing ring. When the storage capacity of the cold storage agent changes, the pressure in the pipeline will also change accordingly. In the long run, it is easy to reduce the sealing performance of the sealing ring, resulting in leakage, reducing the stability of the temperature detection device during use, and having low practicability. Therefore, it needs to be improved. Summary of the Invention

[0024] S2: During the movement of the insulating shell into the pipeline, under the interaction of the driving mechanism and the outer wall of the pipeline, the two-stage telescopic rod can be driven to operate to push the annular shell to move to the right.

[0026] S4: The temperature value detected by the temperature sensor for the coolant stored in the pipeline is transmitted to the external display control panel through a wire.

[0027] Beneficial effects

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. Through the cooperative design of structures such as a temperature sensor and a sealing mechanism, the insulating shell is connected to the connection hole of the pipeline through threads. Rotate the insulating shell so that its left end moves into the pipeline. During the movement, under the interaction of the driving mechanism and the outer wall of the pipeline, the two-stage telescopic rod can be driven to operate to push the annular shell to move to the right. When the annular shell moves, it pushes the corrugated rubber sleeve to move, causing the corrugated rubber sleeve to be compressed and bulge in a folded state out of the annular groove. The right side of the outer surface of the folded corrugated rubber sleeve is squeezed and fitted with the inner wall of the pipeline. At the same time, when the annular shell moves to the right, it drives the pressing member to squeeze the left side of the outer surface of the folded corrugated rubber sleeve, enabling the folded corrugated rubber sleeve to block the connection hole from the inside of the pipeline. Moreover, the pressure generated by the storage of the coolant in the pipeline facilitates the closer fitting of the corrugated rubber sleeve with the inner wall of the pipeline. The sealing effect is good, and leakage is not likely to occur, improving the stability and practicality of the device, and solving the problem in the prior art that the pressure generated by the storage of the coolant in the pipeline acts on the sealing ring. When the storage amount of the coolant changes, the pressure in the pipeline also changes accordingly. Over time, the sealing performance of the sealing ring is likely to be reduced, leakage is likely to occur, the stability during the use of the temperature detection device is reduced, and the practicality is low.

[0030] 2. Through the cooperative design of structures such as a corrugated rubber sleeve and a moving mechanism, during the process of the annular shell moving and squeezing the corrugated rubber sleeve to fold and bulge to the right, the left side of the inner cavity of the corrugated rubber sleeve drives the guide rail to move to the right. The movement of the guide rail drives the docking plate to move and squeeze the outer frame, causing the outer frame to move and drive the block to separate from the teeth of the locking gear. After that, when the guide rail contacts the roller during movement, it drives the roller to rotate. The rotation of the roller drives the sliding sleeve to move and drives the temperature sensor to move to the left, enabling the temperature sensor to be automatically driven to move outside the protection channel and inserted into the coolant for temperature detection, saving operation steps, without the need to be driven by an additional electronic control system, saving energy, and at the same time facilitating the protection of the temperature sensor during the installation process to avoid damage to the temperature sensor caused by collision.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0041] As Figures 1 to 8 shown, the present invention provides a temperature detection device and its detection method for storing a polymer phase change cool storage agent, including a temperature sensor 1 and a sealing mechanism 2 provided on the outer surface of the temperature sensor 1; the temperature sensor 1 is a thermocouple sensor, and the temperature value detected by the temperature sensor 1 is transmitted to an external display control panel through a wire;

[0042] The sealing mechanism 2 includes an insulating shell 21 sleeved on the outer surface of the temperature sensor 1, an annular groove 22 provided on the left side of the outer surface of the insulating shell 21, a corrugated rubber sleeve 23 movably sleeved on the right side of the inner cavity of the annular groove 22, an annular shell 24 slidably sleeved on the left side of the inner cavity of the annular groove 22, an extrusion piece 3 equidistantly arranged on the right side wall of the annular shell 24 for extruding the corrugated rubber sleeve 23, a two-stage telescopic rod 25 equidistantly arranged on the left side of the annular shell 24, a driving mechanism 4 provided on the right side of the insulating shell 21 for driving the two-stage telescopic rod 25 to operate, a placement cavity 26 provided in the middle of the insulating shell 21, a protective channel 27 provided at the left end of the insulating shell 21 and connected to the placement cavity 26, and a moving mechanism 5 provided on the right side of the inner cavity of the corrugated rubber sleeve 23 for driving the temperature sensor 1 to move;

[0043] Among them, the outer surface of the insulating shell 21 is circumferentially provided with threads adapted to the pipeline connection holes, the left and right side walls of the corrugated rubber sleeve 23 are respectively fixedly connected to the right side wall of the annular shell 24 and the right side of the inner cavity of the annular groove 22, the right end of the temperature sensor 1 passes through the protective channel 27 and extends into the inner cavity of the placement cavity 26, and the outer surface of the temperature sensor 1 is sealed and slidably connected to the inner cavity of the protective channel 27, the left fixed end of the two-section telescopic rod 25 is fixedly connected to the left side of the inner cavity of the annular groove 22, a sealing plate 241 is movable left and right in the inner cavity of the annular shell 24, a group of first ventilation holes 242 are circumferentially equidistantly opened on the right side wall of the annular shell 24 near the outer edge, and a group of second ventilation holes 243 are circumferentially equidistantly opened on the right side wall of the annular shell 24 near the center, the first ventilation holes 242 and the second ventilation holes 243 are respectively connected to the inner cavity of the annular shell 24, and a third ventilation hole 244 is opened on the right side of the outer surface of the corrugated rubber sleeve 23.

[0044] When in use, in the initial state, the corrugated rubber sleeve 23 is located in the annular groove 22 in a stretched state. The operator rotates the insulating shell 21 with a wrench to connect it to the connecting hole of the pipeline through a thread, so that the left end of the insulating shell 21 can move into the pipeline. During the movement, the driving mechanism 4 interacts with the outer wall of the pipeline to drive the two-stage telescopic rod 25 to operate and push the annular shell 24 to move to the right. When the annular shell 24 moves, it pushes the corrugated rubber sleeve 23 to move, so that the corrugated rubber sleeve 23 is compressed and folded and bulged to the Outside the annular groove 22, the right side of the outer surface of the folded corrugated rubber sleeve 23 is squeezed and fitted with the inner wall of the pipeline. At the same time, when the annular shell 24 moves to the right, it drives the extrusion part 3 to squeeze the left side of the outer surface of the folded corrugated rubber sleeve 23, so that the folded corrugated rubber sleeve 23 can be sealed from the docking hole inside the pipeline. The pressure generated by the refrigerant stored in the pipeline makes it easier for the corrugated rubber sleeve 23 to fit more closely with the inner wall of the pipeline, with good sealing effect, less likely to leak, and improved stability and practicality of the device.

[0045] It should be noted that when the corrugated rubber sleeve 23 is compressed and fits against the inner wall of the pipeline, it can drive the operation of the moving mechanism 5. Through the moving mechanism 5, the temperature sensor 1 can be driven to move leftward outside the protection channel 27, so that the temperature sensor 1 is in direct contact with the cold storage agent for measurement. This facilitates the protection of the temperature sensor 1 during the installation process, avoiding damage to the temperature sensor 1 caused by collision. At the same time, when the installation is completed, the temperature sensor 1 can be automatically driven to move outside the protection channel 27 and inserted into the cold storage agent for temperature detection, saving operation steps and eliminating the need for additional driving through an electric control system, thus saving energy.

[0046] As Figure 3 and Figure 4 shown, the driving mechanism 4 includes a hexagonal nut 41 fixedly sleeved on the outer surface of the right side of the insulating shell 21, an annular air chamber 42 opened in the hexagonal nut 41, an annular sliding plate 43 moving left and right in the annular air chamber 42, a pressing plate 44 slidably sleeved on the outer surface of the insulating shell 21 to the left of the hexagonal nut 41, and a group of air delivery channels 45 circumferentially and equidistantly opened on the right side of the inner cavity of the annular air chamber 42;

[0047] Among them, a group of connecting rods penetrating into the annular air chamber 42 are circumferentially and equidistantly fixedly installed on the right side wall of the pressing plate 44, and the right ends of the connecting rods are fixedly connected to the left side wall of the annular sliding plate 43. One end of the air delivery channel 45 is communicated with the fixed end of the two-stage telescopic rod 25, and a group of two-stage spring push rods are circumferentially and equidistantly fixedly installed on the right side of the inner cavity of the annular air chamber 42, and the left ends of the two-stage spring push rods are fixedly connected to the right side wall of the annular sliding plate 43.

[0048] During use, the operator rotates the insulating shell 21 through a wrench to connect it to the connection hole of the pipeline through threads. When the left end of the insulating shell 21 moves into the pipeline, under the interaction force after the left side wall of the pressing plate 44 fits against the outer surface of the pipeline, the pressing plate 44 can drive the annular sliding plate 43 through the connecting rod to compress the air in the inner cavity of the annular air chamber 42, and convey the air through the air delivery channel 45 into the fixed end of the two-stage telescopic rod 25. The output end of the two-stage telescopic rod 25 can be driven to extend by the compressed air. When the two-stage telescopic rod 25 extends, it can push the annular shell 24 to move, driving the corrugated rubber sleeve 23 to be compressed into a folded and bulging state.

[0049] As Figure 5 shown, the extrusion member 3 includes a group of mounting seats 31 circumferentially and equidistantly fixed on the right side wall of the annular shell 24. An extrusion rod 32 is hinged in the inner cavity of the mounting seat 31, and a tension spring 33 is fixedly installed on the right side of the mounting seat 31;

[0050] Among them, the right end of the extrusion rod 32 is movably connected to the outer surface of the corrugated rubber sleeve 23, and one end of the tension spring 33 is fixedly connected to the outer surface of the extrusion rod 32.

[0051] During use, when the annular shell 24 moves to the right, it drives the extrusion rod 32 to move through the mounting seat 31. Under the pulling force of the tension spring 33, the extrusion rod 32 can extrude the left side of the outer surface of the corrugated rubber sleeve 23 in the folded state, enabling the right side of the outer surface of the corrugated rubber sleeve 23 in the folded state to fit more closely to the inner cavity of the pipeline, further improving the sealing effect.

[0052] As Figure 6 and Figure 7 shown, the moving mechanism 5 includes a mounting ring 51 fixedly sleeved on the right side of the inner cavity of the corrugated rubber sleeve 23, a group of mounting frames 52 circumferentially and equidistantly fixed in the inner cavity of the mounting ring 51, a sliding sleeve 53 that moves left and right on the group of mounting frames 52, a roller 54 rotatably mounted in the inner cavity of the mounting frame 52 by a rotating shaft for driving the sliding sleeve 53 to move, a guide rail 55 fixed on the left side of the inner cavity of the corrugated rubber sleeve 23 for driving the roller 54 to rotate, and a locking mechanism 6 arranged in the mounting frame 52 for limiting the roller 54;

[0053] Among them, the sliding sleeve 53 is located in the inner cavity of the placement cavity 26. The right side of the outer surface of the temperature sensor 1 is fixedly connected to the inner ring of the sliding sleeve 53. The mounting frame 52 penetrates into the placement cavity 26, and the outer ring of the roller 54 extends into the placement cavity 26. The outer ring of the roller 54 is movably connected to the outer surface of the sliding sleeve 53 and the outer surface of the guide rail 55.

[0054] During use, when the annular shell 24 moves to squeeze the corrugated rubber sleeve 23 to fold and bulge to the right, the left side of the inner cavity of the corrugated rubber sleeve 23 drives the guide rail 55 to move to the right. When the guide rail 55 moves and contacts the roller 54, it can drive the roller 54 to rotate. When the roller 54 rotates, it can drive the sliding sleeve 53 to move and drive the left end of the temperature sensor 1 to move outside the inner cavity of the protection channel 27, facilitating the automatic driving of the temperature sensor 1 to move and insert into the coolant for temperature detection, saving operation steps, without the need to drive separately through an electric control system, and saving energy.

[0055] As Figure 8 shown, the locking mechanism 6 includes a locking gear 61 fixedly sleeved on the rotating shaft of the roller 54, an outer frame 62 sleeved outside the locking gear 61, a clamping block 63 fixed on the side of the inner cavity of the outer frame 62 close to the sliding sleeve 53, and docking plates 64 symmetrically fixed on both sides of the outer surface of the guide rail 55;

[0056] Among them, the clamping block 63 is movably connected to the teeth of the locking gear 61. The outer surface of the docking plate 64 is movably connected to the side of the outer surface of the outer frame 62 away from the sliding sleeve 53. Two chutes are symmetrically opened in the inner cavity of the outer frame 62. The outer surface of the outer frame 62 is slidably connected to the inner cavity of the chute through a connecting block. A compression spring rod 65 is fixedly installed on the side of the inner cavity of the chute close to the sliding sleeve 53. The output end of the compression spring rod 65 is fixedly connected to the outer surface of the connecting block.

[0057] During use, under the elastic force of the compression spring rod 65 in the initial state, the outer frame 62 can be driven to drive the engaging block 63 to engage with the teeth of the locking gear 61, restricting the rotation of the roller 54, thereby preventing the temperature sensor 1 from moving outside the protection channel 27 and being damaged by collision during the installation process. When the left side of the inner cavity of the corrugated rubber sleeve 23 drives the guide rail 55 to move to the right, the movement of the guide rail 55 can drive the docking plate 64 to move and extrude the outer frame 62, causing the outer frame 62 to move and drive the engaging block 63 to separate from the teeth of the locking gear 61, facilitating the movement of the guide rail 55 to drive the rotation of the roller 54.

[0058] A temperature detection method for storing a polymer phase change coolant includes the following usage steps:

[0059] S1: Insert the left end of the insulating shell 21 into the connection hole of the pipeline. The operator rotates the insulating shell 21 through a wrench to connect it to the connection hole of the pipeline by thread, driving the insulating shell 21 to move into the pipeline.

[0060] S2: During the movement of the insulating shell 21 into the pipeline, under the mutual force between the left side wall of the abutting plate 44 and the outer surface of the pipeline, the abutting plate 44 can drive the annular sliding plate 43 through the connecting rod to compress the air in the inner cavity of the annular air chamber 42, and convey the air through the air delivery channel 45 into the fixed end of the two-stage telescopic rod 25. The output end of the two-stage telescopic rod 25 is elongated by the compressed air, and the output end of the two-stage telescopic rod 25 elongates to push the annular shell 24 to move, driving the corrugated rubber sleeve 23 to be compressed and protrude out of the annular groove 22 in a folded and bulged state. The right side of the outer surface of the folded and bulged corrugated rubber sleeve 23 is squeezed and fitted with the inner wall of the pipeline. At the same time, the annular shell 24 moves to the right to drive the extrusion rod 32 to move through the mounting seat 31. Under the pulling force of the tension spring 33, the extrusion rod 32 can squeeze the left side of the outer surface of the folded and bulged corrugated rubber sleeve 23, making the right side of the outer surface of the folded and bulged corrugated rubber sleeve 23 fit more closely with the inner cavity of the pipeline, and sealing the connection hole from the inside of the pipeline.

[0061] S3: During the process of the annular shell 24 moving to squeeze the corrugated rubber sleeve 23 to fold and bulge to the right, the left side of the inner cavity of the corrugated rubber sleeve 23 drives the guide rail 55 to move to the right. The movement of the guide rail 55 drives the docking plate 64 to move and extrude the outer frame 62, causing the outer frame 62 to move and drive the engaging block 63 to separate from the teeth of the locking gear 61. After that, when the guide rail 55 moves and contacts the roller 54, it drives the roller 54 to rotate. The rotation of the roller 54 drives the sliding sleeve 53 to move, driving the left end of the temperature sensor 1 to automatically move outside the inner cavity of the protection channel 27 and insert into the coolant for temperature detection.

[0062] S4: The temperature value detected by the temperature sensor 1 for the coolant stored in the pipeline is transmitted to the external display control panel through a wire.
