Description

Technical Field

[0001] This invention relates to the field of temperature control for prefabricated substation cabins, specifically to a prefabricated cabin temperature control mechanism and its temperature control method. Background Technology

[0002] The temperature control mechanism for prefabricated substation compartments is an important device used to control the internal temperature of the prefabricated compartments to ensure that the substation equipment operates stably in a suitable environment. During use, it monitors the internal temperature of the prefabricated compartments in real time and transmits the data to the control module.

[0003] Chinese patent CN117954992B discloses an adaptive temperature-controlled prefabricated substation cabin for use in the field of prefabricated substation cabins. This cabin incorporates a hydraulic expander, utilizing the thermal expansion and contraction of the expander to control the raising and lowering of a magnetic slider. The magnetic slider, driven by magnetism, moves a control element to adjust the airflow, thereby controlling the ventilation volume of the ventilation system. This achieves adaptive temperature control based on the cabin's internal temperature. As the expander expands, it continuously applies pressure to a pressure sensor, adjusting the fan speed based on the pressure value. Furthermore, the opening size of the ventilation vents is controlled by adjusting the magnetic force of the electromagnet. This allows for adaptive temperature control based on the temperature in different areas of the cabin, effectively improving cooling speed and saving energy. This achieves the adaptive temperature control of the prefabricated cabin, significantly improving cooling performance and saving energy.

[0004] However, this self-adaptive temperature-controlled substation prefabricated module still has the following drawbacks: 1. The airflow control device controls the size of the ventilation opening by controlling the raising and lowering of the roller shutter door composed of folding plates. This method has poor sealing performance and dust is more likely to accumulate when the air flows, which will affect the ventilation effect in the long run. In addition, the cost of multiple simple roller shutter doors and hydraulic expansion devices is relatively high, and their structure is complex and troublesome to maintain later. Furthermore, the folding roller shutter door is not easy to clean, which increases the cleaning cost. 2. In addition, from an aerodynamic perspective, with only one inlet, multiple outlets can actually slow down the airflow. The curved track will further affect the airflow. Furthermore, the design of the roller shutter is not aerodynamic. When the roller shutter is initially opened to a small extent, most of the roller shutter will block some of the wind. This wind is not guided and first impacts the roller shutter laterally before being forcibly compressed and exiting through the outlet. This makes the airflow path less smooth, and over time, the roller shutter is constantly subjected to the lateral thrust of the wind, making it more prone to damage. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated cabin temperature control mechanism and its temperature control method to solve the problems mentioned in the background art.

[0006] The technical solution of the present invention is: a prefabricated cabin temperature control mechanism and its temperature control method, including a prefabricated cabin shell, temperature control structures installed on both sides inside the prefabricated cabin shell, a self-rotating top cover installed on the top of the temperature control structure, and the temperature control structure controls the opening and closing of the self-rotating top cover; The temperature control structure includes a rotary motor, a shaped support component, and a hinge assembly. The rotary motor drives the shaped support component to rise and rotate through the hinge assembly to open and close the self-rotating top cover.

[0007] Furthermore, the temperature control structure also includes a protective shell, and there are two sets of protective shells. The two sets of protective shells are respectively installed on both sides inside the prefabricated cabin shell and are symmetrically distributed. A limit plate is installed on one side inside the protective shell, and the rotary motor is installed on the other side inside the protective shell. The output end of the rotary motor is equipped with a first connecting plate of the hinge assembly, and the output end of the first connecting plate is connected through the limit plate.

[0008] Furthermore, the limiting plate is internally embedded with a Y-shaped limiting slide rail, one side of which is an upright track, and the other side of which is a track that bends towards the top, and the bent track is connected to the upright track at the middle position.

[0009] Furthermore, the end of the first connecting plate away from the rotating motor is hinged to a second connecting plate, and the end of the second connecting plate away from the first connecting plate is hinged to a non-standard support member.

[0010] Furthermore, the irregular support member has an irregular shape, and the top of the irregular support member is fixed to the self-rotating top cover. A second limiting slider is installed at the bottom end of the irregular support member near the limiting plate. The irregular support member and the second connecting plate are hinged together through the second limiting slider.

[0011] Furthermore, a first limiting slider is installed at the top of the irregular support member near the limiting plate, and the first limiting slider and the second limiting slider slide within the Y-shaped limiting slide rail. The height of the end of the irregular support member near the vertical track of the Y-shaped limiting slide rail is half the height of the vertical track of the Y-shaped limiting slide rail, and the first limiting slider and the second limiting slider are installed at the end of the irregular support member near the vertical track of the Y-shaped limiting slide rail.

[0012] Furthermore, a first perforated partition is installed at the bottom of the temperature control structure, and a temperature control fan is installed at the bottom of the first perforated partition. There are four sets of temperature control fans, and a support frame is installed at the bottom of the four sets of temperature control fans. The temperature control fans and the self-turning top cover are fixed by the support frame, and a second perforated partition is installed at the bottom of the support frame.

[0013] Furthermore, observation holes are embedded on both sides of the prefabricated cabin shell, and dust plugs are connected through the interior of the observation holes.

[0014] A temperature control method for a prefabricated cabin temperature control mechanism includes the following steps: S1. An external power supply starts a rotary motor to drive the first connecting plate to rotate. The connection point of the first connecting plate and the second connecting plate is hinged. The second connecting plate and the irregular support are hinged together by a second limiting slider. The top and bottom ends of the irregular support near the limiting plate are respectively equipped with a first limiting slider and a second limiting slider. When the first connecting plate rotates around the output end of the rotary motor, the irregular support can be pushed upward through mechanical linkage. S2. Because the first and second limit sliders slide within the Y-shaped limit slide rail, when the first and second limit sliders move to the top, the rotary motor continues to deliver power. The first limit slider reaches the top of the slide groove, and the second limit slider moves to the other section of the Y-shaped limit slide rail. At this time, the irregular support can be flipped. S3. The rotary motor drives the first connecting plate to rotate and a series of mechanical linkages enable the irregular support to rise and then flip. Because the top of the irregular support is fixed to one side of the bottom of the self-flipping top cover, the self-flipping top cover will rise and leave the restriction of the prefabricated cabin shell first, and then flip to open the top cover of the prefabricated cabin shell. S4. This structure, in conjunction with the second hollowed-out partition at the bottom, allows airflow inside the prefabricated cabin shell to achieve the purpose of cooling. When the airflow flows, it will drive the temperature control fan to rotate. The rotation of the temperature control fan can further accelerate the airflow speed, thereby using wind energy to remove the heat inside the prefabricated cabin shell to achieve the purpose of cooling. S5. Additionally, observation holes are embedded on both sides of the prefabricated cabin shell. When the internal temperature of the prefabricated cabin shell is too high, causing the gas to expand and the air pressure to rise, the dust plug inside the observation hole can be pulled out to release the air pressure and avoid the risk of explosion inside the prefabricated cabin due to gas expansion.

[0015] This invention provides an improved prefabricated cabin temperature control mechanism and method, which, compared with the prior art, has the following improvements and advantages: Firstly, the structure is simple and low-cost. Before the self-tilting top cover is raised, the self-tilting top cover and the prefabricated cabin shell are fitted together and sealed, which has a good sealing effect. Moreover, the surface of the self-tilting top cover is smooth and easier to clean than the self-tilting top cover of a folding roller shutter door, because the air flow will carry the dust flow, and the dust is more likely to remain on the trajectory of the air flow. Specifically, an external power source starts a rotary motor to rotate the first connecting plate. The first and second connecting plates are hinged together, and the second connecting plate and the irregular support member are hinged together via a second limiting slider. The top and bottom ends of the irregular support member near the limiting plate are respectively equipped with the first and second limiting sliders. When the first connecting plate rotates around the output end of the rotary motor, it can mechanically push the irregular support member upwards. Because the first and second limiting sliders slide within the Y-shaped limiting rail, when the first and second limiting sliders reach the top, the rotary motor continues to supply power. The first limiting slider reaches the top of the groove, and the second limiting slider moves towards the Y-shaped limiting rail. When the other section of the slide rail forks and moves, the irregular support component can flip. The rotating motor drives the first connecting plate to rotate, and a series of mechanical linkages enable the irregular support component to rise and then flip. Because the top of the irregular support component is fixed to one side of the bottom of the self-flipping top cover, the self-flipping top cover will first rise away from the restriction of the prefabricated cabin shell, and then flip to open the top cover of the prefabricated cabin shell. This structure, in conjunction with the second hollow partition at the bottom, allows airflow inside the prefabricated cabin shell to achieve the purpose of cooling. When the airflow flows, it will drive the temperature control fan to rotate. The rotation of the temperature control fan can further accelerate the airflow speed, thereby using wind energy to remove heat from the prefabricated cabin shell to achieve the purpose of cooling.

[0016] Secondly, the structure has only two ventilation openings, one at the top and one at the bottom. The single fixed inlet and outlet, which are directly opposite each other, allow the wind to pass through more quickly. This is because when the airflow forms a fixed trajectory, its flow speed will increase under the same wind power. This makes the single outlet faster and faster with the change in wind speed. In addition, the top is prone to dust accumulation, so the top of the prefabricated cabin shell is sealed with a self-rotating top cover. When the self-rotating top cover is opened, it tilts and rotates, so that the wind always flows along the tilted self-rotating top cover, avoiding the lateral thrust on the self-rotating top cover and extending the service life of the self-rotating top cover. In addition, observation holes are embedded on both sides of the prefabricated cabin shell. When it is necessary to observe and inspect the environment inside the prefabricated cabin shell, the dust plugs inside the observation holes can be pulled out for timely inspection and maintenance.

Detailed Implementation

[0019] The following will be combined with the appendix Figures 1 to 7 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] The present invention provides a prefabricated cabin temperature control mechanism and its temperature control method through improvements, including a prefabricated cabin shell 2, temperature control structures 5 installed on both sides inside the prefabricated cabin shell 2, a self-flipping top cover 1 installed on the top of the temperature control structure 5, and the temperature control structure 5 controlling the opening and closing of the self-flipping top cover 1. The temperature control structure 5 includes a rotary motor 504, a special-shaped support 507 and a hinge assembly. The rotary motor 504 drives the special-shaped support 507 to rise and flip through the hinge assembly to open and close the self-flipping top cover 1. The temperature control structure 5 also includes a protective shell 501, and the protective shell 501 is provided in two sets. The two sets of protective shells 501 are respectively installed on both sides inside the prefabricated cabin shell 2 and are symmetrically distributed. A limit plate 502 is installed on one side inside the protective shell 501, and a rotary motor 504 is installed on the other side inside the protective shell 501. The output end of the rotary motor 504 is equipped with a first connecting plate 505 of the hinge assembly. The rotary motor 504 is started by an external power supply to drive the first connecting plate 505 to rotate, and the output end of the first connecting plate 505 is connected through the limit plate 502. The limiting plate 502 is embedded with a Y-shaped limiting slide rail 503. One side of the Y-shaped limiting slide rail 503 is an upright track, and the other side of the Y-shaped limiting slide rail 503 is a track that bends towards the top. The bent track is connected to the upright track at the middle position. The first connecting plate 505 is hinged to the end away from the rotary motor 504 with a second connecting plate 506, and the second connecting plate 506 is hinged to the end away from the first connecting plate 505 with a special-shaped support member 507. The irregular support member 507 has an irregular shape, and the top of the irregular support member 507 is fixed to the self-rotating top cover 1. Before the self-rotating top cover 1 is raised, the self-rotating top cover 1 and the prefabricated cabin shell 2 are fitted together and sealed, and the sealing effect is also good. Because the top is prone to dust accumulation, the top of the prefabricated cabin shell 2 is sealed with the self-rotating top cover 1. In addition, the self-rotating top cover 1 will tilt and rotate when opened, so that the air always flows along the tilted self-rotating top cover 1, avoiding the lateral thrust on the self-rotating top cover 1, extending the service life of the self-rotating top cover 1. Finally, the surface of the self-rotating top cover 1 is smooth and easier to clean than the self-rotating top cover 1 of the folding roller shutter door. The bottom end of the irregular support 507 near the limiting plate 502 is equipped with a second limiting slider 509, and the irregular support 507 and the second connecting plate 506 are hinged together by the second limiting slider 509. The top of the irregular support member 507 near the limiting plate 502 is equipped with a first limiting slider 508, and the first limiting slider 508 and the second limiting slider 509 slide within the Y-shaped limiting slide rail 503. When the first connecting plate 505 rotates around the output end of the rotary motor 504, the irregular support member 507 can be pushed upward through mechanical linkage. The height of the end of the irregular support member 507 near the vertical track of the Y-shaped limiting slide rail 503 is half that of the vertical track of the Y-shaped limiting slide rail 503, and the first limiting slider 508 and the second limiting slider 509 are installed at the end of the irregular support member 507 near the vertical track of the Y-shaped limiting slide rail 503. Because the first limiting slider 508 and the second limiting slider 509 slide within the Y-shaped limiting slide rail 503, when the first limiting slider 508 and the second limiting slider 509 move to the top, the rotary motor 504 continues to deliver power. The first limiting slider 508 reaches the top of the slide groove, and the second limiting slider 509 moves to the other section of the slide rail that branches off from the Y-shaped limiting slide rail 503. At this time, the irregular support member 507 can be flipped. Through the rotary motor 504 driving the first connecting plate 505 to rotate and a series of mechanical linkages, the irregular support member 507 achieves the action of first rising and then flipping. Because the top of the irregular support 507 is fixed to one side of the bottom of the self-rotating top cover 1, the self-rotating top cover 1 will first rise away from the restriction of the prefabricated cabin shell 2, and then rotate to open the top cover of the prefabricated cabin shell 2. This structure, in conjunction with the second hollow partition 7 at the bottom, allows the airflow inside the prefabricated cabin shell 2 to achieve the purpose of cooling. The structure has only two ventilation openings, one at the top and one at the bottom. The single fixed entrance and exit, which are directly opposite each other, allow the wind to pass through more quickly. This is because when the air flow forms a fixed trajectory, its flow speed will increase under the same wind force, which makes the single outlet faster and faster as the wind speed changes. The temperature control structure 5 is equipped with a first hollow partition plate 4 at the bottom, and a temperature control fan 6 is installed at the bottom of the first hollow partition plate 4. There are four sets of temperature control fans 6. A support frame 8 is installed at the bottom of the four sets of temperature control fans 6. The temperature control fan 6 and the self-reversing top cover 1 are fixed by the support frame 8. A second hollow partition plate 7 is installed at the bottom of the support frame 8. When the airflow moves, it drives the temperature control fan 6 to rotate. The rotation of the temperature control fan 6 can further accelerate the airflow speed, thereby using wind energy to remove the heat inside the prefabricated cabin shell 2 to achieve the purpose of cooling. This structure is simple and has a low cost. The prefabricated cabin shell 2 has observation holes 9 embedded on both sides, and dust plugs 3 are connected through the inside of the observation holes 9. When it is necessary to observe and inspect the environment inside the prefabricated cabin shell 2, the dust plugs 3 inside the observation holes 9 can be pulled out for timely inspection.

[0021] A temperature control method for a prefabricated cabin temperature control mechanism includes the following steps: S1. An external power supply starts the rotary motor 504, which drives the first connecting plate 505 to rotate. The connection point of the first connecting plate 505 and the second connecting plate 506 is hinged. The second connecting plate 506 and the irregular support member 507 are hinged together by the second limiting slider 509. The top and bottom ends of the irregular support member 507 near the limiting plate 502 are respectively equipped with the first limiting slider 508 and the second limiting slider 509. When the first connecting plate 505 rotates around the output end of the rotary motor 504, the irregular support member 507 can be pushed upward through mechanical linkage. S2. Because the first limiting slider 508 and the second limiting slider 509 slide within the Y-shaped limiting slide rail 503, when the first limiting slider 508 and the second limiting slider 509 move to the top, the rotary motor 504 continues to deliver power. The first limiting slider 508 reaches the top of the slide groove, and the second limiting slider 509 moves to the other section of the slide rail that branches off from the Y-shaped limiting slide rail 503. At this time, the irregular support member 507 can be flipped. S3, the rotary motor 504 drives the first connecting plate 505 to rotate and a series of mechanical linkages enable the irregular support 507 to rise first and then flip. Because the top of the irregular support 507 is fixed to one side of the bottom of the self-flipping top cover 1, it will drive the self-flipping top cover 1 to rise first and leave the restriction of the prefabricated cabin shell 2, and then flip to open the top cover of the prefabricated cabin shell 2. S4. This structure, in conjunction with the second hollowed-out partition 7 at the bottom, allows airflow inside the prefabricated cabin shell 2 to achieve the purpose of cooling. When the airflow is flowing, it will drive the temperature control fan 6 to rotate. The rotation of the temperature control fan 6 can further accelerate the airflow speed, thereby using wind energy to remove the heat inside the prefabricated cabin shell 2 to achieve the purpose of cooling. S5. Additionally, observation holes 9 are embedded on both sides of the prefabricated cabin shell 2. When the internal temperature of the prefabricated cabin shell 2 is too high, causing the gas to expand and the air pressure to rise, the dust plug 3 inside the observation hole 9 can be pulled out so that the air pressure can be released, avoiding the risk of explosion inside the prefabricated cabin due to gas expansion.

[0022] Working principle: First, the external power supply starts the rotary motor 504, which drives the first connecting plate 505 to rotate. The connection point of the first connecting plate 505 and the second connecting plate 506 is hinged, and the second connecting plate 506 and the irregular support member 507 are hinged together by the second limiting slider 509. The top and bottom ends of the irregular support member 507 near the limiting plate 502 are respectively equipped with the first limiting slider 508 and the second limiting slider 509. When the first connecting plate 505 rotates around the output of the rotary motor 504... When the outlet rotates, the irregular support 507 can be pushed upward through mechanical linkage. Because the first limiting slider 508 and the second limiting slider 509 slide within the Y-shaped limiting slide rail 503, when the first limiting slider 508 and the second limiting slider 509 move to the top, the rotary motor 504 continues to deliver power. The first limiting slider 508 reaches the top of the slide groove, and the second limiting slider 509 moves to the other section of the slide rail that branches off from the Y-shaped limiting slide rail 503. At this time, the irregular support 507 can be flipped.

[0023] Then, the rotary motor 504 drives the first connecting plate 505 to rotate, and a series of mechanical linkages cause the irregular support 507 to rise and then flip. Because the top of the irregular support 507 is fixed to one side of the bottom of the self-flipping top cover 1, the self-flipping top cover 1 will rise first to leave the restriction of the prefabricated cabin shell 2, and then flip to open the top cover of the prefabricated cabin shell 2. This structure, in conjunction with the second hollow partition 7 at the bottom, allows airflow inside the prefabricated cabin shell 2 to achieve the purpose of cooling. When the airflow is flowing, it will drive the temperature control fan 6 to rotate. The rotation of the temperature control fan 6 can further accelerate the airflow speed, thereby carrying away the heat inside the prefabricated cabin shell 2 through wind energy to achieve the purpose of cooling. This structure is simple and has a low cost. Before the self-flipping top cover 1 is raised, the self-flipping top cover 1 and the prefabricated cabin shell 2 are in a fitted sealing method, and the sealing effect is also good. Moreover, the surface of the self-flipping top cover 1 is smooth and easier to clean than the folding roller shutter door self-flipping top cover 1, because the airflow will carry the dust flow, and the dust is more likely to remain on the trajectory of the airflow. In addition, the structure has only two ventilation openings, one at the top and one at the bottom. The single fixed inlet and outlet, which are directly opposite each other, allow the wind to pass through more quickly. This is because when the airflow forms a fixed trajectory, its flow speed will increase under the same wind power. This makes the single outlet faster and faster with the change of wind speed. In addition, the top is prone to dust accumulation, so the top of the prefabricated cabin shell 2 is sealed with a self-rotating top cover 1. When the self-rotating top cover 1 is opened, it will tilt and rotate, so that the wind always flows along the tilted self-rotating top cover 1, avoiding the lateral thrust on the self-rotating top cover 1 and extending the service life of the self-rotating top cover 1.

[0024] Finally, observation holes 9 are embedded on both sides of the prefabricated cabin shell 2. When the internal temperature of the prefabricated cabin shell 2 is too high, causing the gas to expand and the air pressure to rise, the dust plug 3 inside the observation hole 9 can be pulled out so that the air pressure can be released, avoiding the risk of explosion inside the prefabricated cabin due to gas expansion.

The first limiting slider (508) reaches the top of the slide groove, and the second limiting slider (509) moves to the other section of the slide rail that branches off from the Y-shaped limiting slide rail (503). At this time, the irregular support member (507) can be flipped. S3. The rotary motor (504) drives the first connecting plate (505) to rotate and a series of mechanical linkages enable the irregular support (507) to rise first and then flip. Because the top of the irregular support (507) and one side of the bottom of the self-flipping top cover (1) are fixed, the self-flipping top cover (1) will rise first and leave the restriction of the prefabricated cabin shell (2), and then flip to open the top cover of the prefabricated cabin shell (2). S4. This structure, in conjunction with the second hollowed-out partition (7) at the bottom, allows airflow inside the prefabricated cabin shell (2) to achieve the purpose of cooling. When the airflow flows, it will drive the temperature control fan (6) to rotate. The rotation of the temperature control fan (6) can further accelerate the airflow speed, thereby using wind energy to remove the heat inside the prefabricated cabin shell (2) to achieve the purpose of cooling. S5. Additionally, observation holes (9) are embedded on both sides of the prefabricated cabin shell (2). When the internal temperature of the prefabricated cabin shell (2) is too high, causing the gas to expand and the air pressure to rise, the dust plug (3) inside the observation hole (9) can be pulled out so that the air pressure can be released, thus avoiding the risk of gas expansion causing an explosion inside the prefabricated cabin.
