Description

A zone control device for airport heating pipeline system Technical Field

[0001] This utility model relates to the field of temperature zone control technology, specifically a zone control device for airport heating pipeline systems. Background Technology

[0002] Airport heating pipeline systems are important infrastructure for ensuring suitable temperatures in various areas of an airport. They generally consist of a heat source, pipelines, control equipment, and heat exchange equipment. They can be distinguished by the heat medium or circulation method: hot water heating systems use hot water as the heat medium, steam heating systems use steam as the heat medium; natural circulation hot water heating systems rely on the density difference of the heat medium itself for circulation, and mechanical circulation hot water heating systems use a circulation pump for circulation.

[0003] Temperature zone control refers to the technique or method of dividing a large space or system into multiple different zones, and then independently and precisely controlling and adjusting the temperature of each zone according to its specific needs and characteristics. In this way, different zones can reach different temperature setpoints at the same time to meet the specific temperature environment requirements of personnel, equipment, or processes in each zone.

[0004] Most existing airport heating pipeline systems using zone control devices typically employ a combination of components such as electric regulating valves. By controlling the opening of the electric regulating valves, the flow rate within the heating pipeline is adjusted, thereby regulating the temperature of different zones according to the required temperature. Based on the signals received by the electric regulating valves, the motor is driven to change the valve opening, thus achieving precise control of the water flow rate within the heating pipeline and achieving the purpose of zone temperature control. However, after controlling the flow rate of the heating medium inside the pipeline, it is necessary to wait for the temperature to decrease slowly based on the flow rate of the heating medium. This results in a slow temperature drop during zone temperature control, leading to a decrease in the efficiency of temperature zone control.

[0005] Therefore, this utility model provides a zone control device for airport heating pipeline systems to solve the above problems. Summary of the Invention

The heat insulation plate and the sliding block are both corresponding to the adjustment pipe. A drive motor is fixedly connected to the upper surface of the hollow box.

[0011] As a preferred technical solution of this application, the control mechanism further includes a servo motor fixedly connected to one side of the hollow box. The output end of the servo motor is connected to a rotating rod via a belt drive. The rotating rod is rotatably connected to the inside of the adjustment pipe via a bearing seat. The threaded rod is rotatably connected to the inside of the hollow box.

[0012] As a preferred technical solution of this application, the control mechanism further includes a flip plate fixedly connected to the surface of the rotating rod. The flip plate corresponds to the adjustment pipe and is rotatably connected to the inside of the adjustment pipe through the rotating rod.

[0013] As a preferred technical solution of this application, the feeding mechanism includes two conveying pipes that are respectively fixedly connected to the upper surface of the corresponding hollow box and communicate with the hollow box. One end of the conveying pipe is fixedly connected to a water pump whose output end is fixedly connected to the conveying pipe. The input end of the water pump is fixedly connected to a water collection tank. The surface of the water collection tank is provided with a scale plate.

One end of the regulating pipe is fixedly connected to a flow sensor through a flange.

[0016] (III) Beneficial Effects

[0017] Through the coordinated operation of the control mechanism and the feeding mechanism, when the temperature in the area is too high, the drive motor is activated, causing the threaded rod to move the sliding block downwards. This allows the sliding block to insert into the regulating pipe, changing its diameter and thus adjusting the flow rate and velocity of the heat transfer medium inside. This, in turn, adjusts the temperature within the area. Furthermore, the coolant inside the hollow box lowers the temperature of the sliding block, resulting in rapid cooling of the heat transfer medium as it flows through it. This improves the efficiency of temperature control in the area. The sliding block seals the hollow box, preventing coolant from entering the regulating pipe. The heat insulation plate further prevents the coolant from affecting the heat transfer medium. The multiple control mechanisms enable zoned temperature control, making temperature regulation in different areas of the airport more convenient.

[0018] By setting up a control mechanism and other structures, when it is necessary to control the temperature in the area, the servo motor is activated, which causes the belt to drive the rotating rod to rotate. This causes the tilting plate to rotate inside the regulating pipe, changing the inner diameter of the regulating pipe, thereby adjusting the flow rate and volume of the heat medium, so that the heating is raised, and the temperature in the area is further adjusted, making the temperature in the area easier to control.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a zone control device for an airport heating pipeline system, as shown in Figures 1-5. The zone control device for the airport heating pipeline system includes a main pipeline 1. A control mechanism is installed in a rectangular array on the surface of the main pipeline 1. A feeding mechanism is installed on the surface of the control mechanism. A circulation mechanism is installed at one end of the main pipeline 1. The circulation mechanism includes a circulation pump 15 fixedly connected to one end of the main pipeline 1 and whose input end is connected to one end of the main pipeline 1. A circulation pipe 16 is fixedly connected to the output end of the circulation pump 15. One end of the circulation pipe 16 is fixedly connected to the main pipeline 1 and the circulation pipe 16 is connected to the main pipeline 1. Through the setting of the circulation pump 15, the heat medium circulates in the main pipeline 1 and the branch pipeline 2. When it is necessary to cool down the area temperature;

[0028] The feeding mechanism includes two conveying pipes 12 that are fixedly connected to the upper surface of the corresponding hollow box 4 and communicate with the hollow box 4. One end of the conveying pipe 12 is fixedly connected to a water pump 13 whose output end is fixedly connected to the conveying pipe 12. The input end of the water pump 13 is fixedly connected to a water collection tank 14. Through the setting of the water pump 13, the coolant inside the water collection tank 14 is transferred to the inside of the conveying pipe 12, so that the coolant enters the inside of the hollow box 4 and completes the replenishment of the coolant inside the hollow box 4. This makes the sliding block 5 more stable when accelerating the reduction of the temperature in the area. The surface of the water collection tank 14 is provided with a scale plate, and the inside of the water collection tank 14 is provided with coolant. Through the coolant provided inside the hollow box 4, the sliding block 5 is partially immersed in the coolant, so that the heat medium cools down rapidly when it comes into contact with the sliding block 5 during the flow process, thereby improving the temperature reduction efficiency in the area.

[0029] The control mechanism includes a branch pipe 2 fixedly connected to the surface of the main pipe 1. One end of the branch pipe 2 is fixedly connected to a regulating pipe 3 via a flange. A hollow box 4 is installed on the surface of the regulating pipe 3. A temperature sensor 17 is provided on the surface of the regulating pipe 3. A limiting plate fixedly connected to the hollow box 4 is sleeved on the surface of the temperature sensor 17. A flow sensor 18 is fixedly connected to one end of the regulating pipe 3 via a flange. A sliding block 5 is slidably connected inside the hollow box 4. A heat insulation plate 6 is fixedly connected to the lower surface of the sliding block 5. When the drive motor 7 is started, its output end drives the threaded rod 8 to rotate inside the hollow box 4, which drives the sliding block 5 and the heat insulation plate 6 to move downward, so that the sliding block 5 and the heat insulation plate 6 are inserted into the inside of the regulating pipe 3.

[0030] The hollow box 4 is connected to the regulating pipe 3. The heat insulation plate 6 and the sliding block 5 are both corresponding to the regulating pipe 3. The upper surface of the hollow box 4 is fixedly connected to the drive motor 7. The output end of the drive motor 7 is fixedly connected to the threaded rod 8. The threaded rod 8 is threadedly connected to the inside of the sliding block 5. By sliding the sliding block 5, the diameter of the regulating pipe 3 is changed, and the flow rate and flow of the heat medium inside the regulating pipe 3 are reduced, thereby achieving the effect of zone temperature control.

[0031] The control mechanism also includes a servo motor 9 fixedly connected to one side of the hollow box 4. The output end of the servo motor 9 is connected to a rotating rod 10 via a belt drive. The rotating rod 10 is rotatably connected to the inside of the regulating pipe 3 via a bearing seat. The threaded rod 8 is rotatably connected to the inside of the hollow box 4. The control mechanism also includes a flip plate 11 fixedly connected to the surface of the rotating rod 10. When the area temperature is too low and needs adjustment, the servo motor 9 is started, causing its output end to drive the rotating rod 10 to rotate inside the regulating pipe 3, which in turn drives the flip plate 11 to rotate. This causes the flip plate 11 to be suspended inside the regulating pipe 3, adjusting the internal diameter of the regulating pipe 3, increasing the flow rate and volume of the heat medium, thereby raising the temperature of the airport area. The flip plate 11 corresponds to the regulating pipe 3, and the flip plate 11 is rotatably connected to the inside of the regulating pipe 3 via the rotating rod 10.

[0032] Specifically, when the zone control device of the airport's heating pipeline system is in use: the circulation pump 15 allows the heat medium to circulate within the main pipeline 1 and the branch pipeline 2. When it is necessary to cool the area temperature, the drive motor 7 is started, causing its output end to drive the threaded rod 8 to rotate inside the hollow box 4. This causes the sliding block 5 and the heat insulation plate 6 to move downwards, allowing the sliding block 5 and the heat insulation plate 6 to be inserted into the regulating pipe 3. This changes the diameter of the regulating pipe 3, reducing the flow rate and volume of the heat medium inside the regulating pipe 3, thereby achieving the effect of zone temperature control. At the same time, the coolant inside the hollow box 4 partially immerses the sliding block 5 in the coolant, allowing the heat medium to cool down rapidly when it comes into contact with the sliding block 5 during the flow process, thus improving the temperature cooling efficiency within the area.

[0033] The water pump 13 transfers the coolant from the water tank 14 to the delivery pipe 12, allowing the coolant to enter the hollow box 4 and replenish the coolant inside the hollow box 4. This makes the sliding block 5 more stable when accelerating the reduction of the area temperature. When the area temperature is too low and needs adjustment, the servo motor 9 is activated, causing its output to drive the rotating rod 10 to rotate inside the regulating pipe 3, which in turn drives the flip plate 11 to rotate. This causes the flip plate 11 to be suspended inside the regulating pipe 3, adjusting the internal diameter of the regulating pipe 3 and increasing the flow rate and velocity of the heat medium, thereby raising the temperature of the airport area. Furthermore, the setting of multiple control mechanisms allows for zoned temperature control of different areas of the airport, making airport temperature control more convenient.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
