Description

Technical Field

[0001] The utility model relates to the technical field of fast doors, in particular to a fast door which can prevent rapid temperature loss. Background Art

[0002] Rapid door, also known as fast rolling door or high-speed door, is an efficient and energy-saving industrial door. It is characterized by high-speed operation, with a running speed of more than 0.6 meters per second. It can be opened and closed quickly, thereby achieving rapid isolation and ensuring the dust-free level of workshop air quality. Rapid door has many functions, including heat preservation, cold preservation, insect prevention, windproof, dustproof, sound insulation, fire prevention, odor prevention, lighting, etc. Therefore, it is widely used in food, chemical, textile, electronics, supermarkets, freezing, logistics, warehousing and other places.

[0003] When using existing fast-moving doors in winter, due to the significant temperature difference on both sides of the door body, this often causes a layer of fine water droplets to condense on the surface of the door body on the side with higher temperature. The presence of these water droplets will not only have an adverse effect on the service life of the door body, but more importantly, they may also cause potential damage to the electronic control components inside the door body, thereby affecting the normal operation and use effect of the entire fast-moving door. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a fast door that can avoid rapid temperature loss, so as to solve the technical problem that the presence of water droplets affects the service life of the door body and even has an adverse effect on the internal electronic control components.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fast door capable of preventing rapid temperature loss, comprising a door frame and a door body, air curtains are arranged on both sides of the front surface of the door frame, a guide mechanism is arranged on one side of the air outlet of the air curtain, the guide mechanism comprises a guide plate, the guide plate is rotatably connected to the air curtain through a rotating shaft, an electric push rod is arranged on one side of the guide plate, and both ends of the electric push rod are rotatably connected to the guide plate and the air curtain through mounting ears;

[0006] A first temperature sensor and a humidity sensor are arranged on one side above the front surface of the door frame, and a second temperature sensor is arranged on one side of the back of the door frame.

[0007] By adopting the above technical solution, the control center's retraction operation of the electric push rod is a key step in quickly responding to the condensation of water droplets. By accurately controlling the degree of retraction of the electric push rod, the angle of the guide plate can be adjusted to ensure that the air outlet direction of the air curtain machine can blow directly to the door surface. This precise control not only improves the air drying efficiency, but also effectively avoids the waste of wind energy.

[0008] Furthermore, the guide mechanism is used to guide the air outlet angle of the air curtain machine.

[0009] By adopting the above technical solution, the guide mechanism can accurately control the air outlet angle of the air curtain machine. Through the coordinated action of the guide plate and the electric push rod, the wind blown out by the air curtain machine can be accurately guided to the required direction, that is, the surface of the door body. This precise control ensures the effective use of wind energy and avoids the waste and scattering of wind energy.

[0010] Furthermore, the first temperature sensor and the second temperature sensor respectively monitor the temperature difference between the inside and the outside of the rapid door, and the humidity sensor is used to monitor the humidity of the inner area of ​​the rapid door.

[0011] By adopting the above technical solution, the first temperature sensor and the second temperature sensor respectively monitor the temperature difference between the inside and the outside of the rapid door. This temperature difference monitoring can reflect the temperature changes on both sides of the door body in real time and provide accurate temperature data for the system. By comparing the temperature difference between the inside and the outside, the system can determine whether there is a risk of condensation on the surface of the door body, and thus take corresponding measures to deal with it in time.

[0012] Furthermore, the first temperature sensor, the second temperature sensor, the humidity sensor and the electric push rod are all electrically connected to an external power supply through a control center.

[0013] By adopting the above technical solutions, all sensors and electric push rods can obtain stable and reliable power supply, which means that no matter how the external environment changes, these key components can work continuously and accurately, providing a solid foundation for the normal operation of fast doors.

[0014] Furthermore, the air outlets of the two air curtain machines are located opposite to each other, and the air curtain machines are used to block the entry of cold air from the outside of the rapid door.

[0015] By adopting the above technical solution, the relatively arranged air outlets can form a strong airflow barrier, effectively blocking the cold air on the outside of the rapid door from entering the warm area inside. This barrier effect helps to maintain the temperature stability of the inner area, reduce energy loss, and improve the thermal insulation performance of the rapid door.

[0016] Furthermore, a visual window is provided on the surface of the door body.

[0017] By adopting the above technical solution, the setting of the visual window enhances the practicality of the door body. Through the visual window, people can clearly see the situation on the other side of the door body without having to frequently open the door body for confirmation. This is especially important in places where the indoor environment needs to be kept stable or where high safety requirements are required, such as laboratories, clean rooms, etc.

[0018] Furthermore, an electric control box is provided on one side of the door frame for controlling the working status of the motor and the air curtain machine.

[0019] By adopting the above technical solution, the centralized control function of the electric control box simplifies the operation process. Through the electric control box, users can easily control the start, stop and switching of working modes of the motor and air curtain machine without having to operate each device separately, which greatly improves the convenience and efficiency of operation.

[0020] Furthermore, a winding roller bin is provided at the top of the door frame, and a motor is provided at one side of the winding roller bin.

[0021] By adopting the above technical solution, the winding roller bin is designed to be located at the top of the door frame, so that the door body can be smoothly rolled and unfolded when opening and closing. This layout optimizes space utilization, ensures that the movement trajectory of the door body will not be hindered, and improves the convenience of using the door.

[0022] Furthermore, a photoelectric sensor is arranged below the surface of the door frame, and the photoelectric sensor is used to monitor moving objects inside the door frame.

[0023] By adopting the above technical solution, the real-time monitoring function of the photoelectric sensor enhances the safety performance of the door frame. It can accurately and quickly detect moving objects on the inside of the door frame, such as people and vehicles, so as to timely trigger corresponding safety mechanisms, such as automatic opening of the door or activation of the alarm system, effectively avoiding potential collision risks.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] 1. The utility model uses the guide mechanism, the first temperature sensor, the humidity sensor and the second temperature sensor. When it is detected that water droplets are condensed on the surface of the door body, the control center will control the electric push rod to retract. This action adjusts the angle of the guide plate to ensure that the air outlet direction of the air curtain machine can be directly aimed at the surface of the door body. At the same time, the air curtain machines on both sides will start the blowing operation. The airflow generated by the air curtain machine is guided by the guide plate and blows directly to the inner side of the door body, thereby increasing the air flow rate in the area. This direct blowing method helps to quickly dry the water droplets condensed on the surface of the door body, and prevents the water droplets from being retained and accumulated inside the winding roller bin after the door body is rolled up, thereby reducing the potential risk of damage to external electrical equipment and enhancing its protectiveness;

[0026] 2. The utility model provides an air curtain machine, and the air outlets of the two air curtain machines are arranged opposite to each other, so as to form a strong airflow barrier. This barrier effectively blocks the invasion of cold air from the outside of the rapid door, thereby maintaining the temperature stability of the inside of the door body, which is very important for places that need to maintain a certain temperature environment, such as cold storages, food processing workshops, etc. At the same time, the barrier effect of the air curtain machine can also help reduce energy loss. In cold seasons, the invasion of cold air from the outside will cause the indoor temperature to drop, thereby increasing the energy consumption of the heating system. The barrier effect of the air curtain machine can reduce this unnecessary energy exchange, improve the thermal insulation performance of the building, and thus achieve the goal of energy saving and emission reduction.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] Embodiment 1:

[0035] A fast door that can avoid rapid temperature loss, such as Figure 1-Figure 4As shown, it includes a door frame 1 and a door body 2, air curtains 5 are arranged on both sides of the front surface of the door frame 1, a guide mechanism 6 is arranged on one side of the air outlet of the air curtain 5, the guide mechanism 6 includes a guide plate 601, the guide plate 601 is rotatably connected to the air curtain 5 through a rotating shaft 602, an electric push rod 604 is arranged on one side of the guide plate 601, and both ends of the electric push rod 604 are rotatably connected to the guide plate 601 and the air curtain 5 through mounting ears 603;

[0036] A first temperature sensor 701 and a humidity sensor 702 are arranged on one side above the front surface of the door frame 1, and a second temperature sensor 703 is arranged on the back side of the door frame 1. The contraction operation of the electric push rod 604 by the control center is a key step in quickly responding to the condensation of water droplets. By accurately controlling the contraction degree of the electric push rod 604, the angle of the guide plate 601 can be adjusted to ensure that the air outlet direction of the air curtain machine 5 can be directly blown to the surface of the door body 2. This precise control not only improves the air drying efficiency, but also effectively avoids the waste of wind energy. At the same time, the blowing operation of the air curtain machines 5 on both sides is an important means to quickly remove water droplets on the surface of the door body 2. The strong airflow blows directly to the inner side of the door body 2, which greatly increases the air flow rate in the area, thereby accelerating the evaporation process of the water droplets, which not only effectively prevents the accumulation of water droplets in the winding roller bin 3, but also significantly improves the service life and reliability of the door body 2 and the entire fast door system.

[0037] See also Figure 1 , Figure 4 The guide mechanism 6 is used to guide the air outlet angle of the air curtain machine 5. The guide mechanism 6 can accurately control the air outlet angle of the air curtain machine 5. Through the coordinated action of the guide plate 601 and the electric push rod 604, the wind blown out by the air curtain machine 5 can be accurately guided to the required direction, that is, the surface of the door body 2. This precise control ensures the effective utilization of wind energy and avoids the waste and scattering of wind energy. At the same time, the flexibility of the guide mechanism 6 enables the air curtain machine 5 to adapt to different environments and needs. When water droplets condense on the surface of the door body 2, the control center can adjust the extension degree of the electric push rod 604, thereby changing the angle of the guide plate 601, so that the air outlet of the air curtain machine 5 is more concentratedly blown to the surface of the door body 2.

[0038] See also Figure 1 , Figure 2 , Figure 3The first temperature sensor 701 and the second temperature sensor 703 respectively monitor the temperature difference between the inside and outside of the rapid door, and the humidity sensor 702 is used to monitor the humidity of the inner area of ​​the rapid door. The first temperature sensor 701 and the second temperature sensor 703 respectively monitor the temperature difference between the inside and outside of the rapid door. This temperature difference monitoring can reflect the temperature changes on both sides of the door body 2 in real time and provide accurate temperature data for the system. By comparing the temperature difference between the inside and the outside, the system can determine whether there is a risk of condensation of water droplets on the surface of the door body 2, so as to take corresponding measures in time to deal with it. At the same time, the humidity sensor 702 is used to monitor the humidity of the inner area of ​​the rapid door. The change of humidity has an important influence on the formation of water droplets on the surface of the door body. By real-time monitoring of humidity data, the system can more accurately determine the possibility of condensation of water droplets on the surface of the door body, and adjust the working status of the air curtain machine 5 and the guide mechanism 6 in time to prevent the formation and accumulation of water droplets.

[0039] See also Figure 1 , Figure 2 , Figure 3 The first temperature sensor 701, the second temperature sensor 703, the humidity sensor 702 and the electric push rod 604 are all electrically connected to the external power supply through the control center. All sensors and the electric push rod 604 can obtain a stable and reliable power supply, which means that no matter how the external environment changes, these key components can continue to work accurately, providing a solid foundation for the normal operation of the fast door. At the same time, this centralized power management method simplifies the wiring structure of the system and improves the overall safety and maintainability. The control center can uniformly manage and allocate the power requirements of each component to ensure that each component can operate in the best condition, which not only improves the operating efficiency of the system, but also reduces maintenance costs and failure risks.

This blocking effect helps to maintain the temperature stability of the inner area, reduce energy loss, and improve the thermal insulation performance of the rapid door. At the same time, due to the blocking effect of the air curtain machine 5, the cold air from the outside is blocked outside the door body 2, and the loss of hot air from the inside is prevented, thereby improving the thermal insulation performance of the rapid door.

[0042] See also Figure 1 , Figure 2 , Figure 3A visual window 10 is provided on the surface of the door body 2. The setting of the visual window 10 enhances the practicality of the door body 2. Through the visual window 10, people can clearly see the situation on the other side of the door body 2 without frequently opening the door body 2 for confirmation. This is especially important in places where the indoor environment needs to be kept stable or where safety requirements are high, such as laboratories, clean rooms, etc. At the same time, the visual window 10 also improves the aesthetics of the door body 2. The appropriate style and material of the visual window 10 can be selected according to the overall architectural style or personal preferences, so that the door body 2 can maintain functionality while being harmoniously integrated with the surrounding environment, thereby enhancing the overall aesthetic feeling.

The winding roller bin 3 is designed to be located at the top of the door frame 1, so that the door body 2 can be smoothly rolled up and unfolded when opening and closing. This layout optimizes space utilization, ensures that the movement trajectory of the door body 2 will not be hindered, and improves the convenience of using the door. At the same time, the motor 4 is arranged on one side of the winding roller bin 3 to facilitate driving the winding and unfolding of the door body 2. The compact layout of the motor 4 not only reduces the footprint of the overall equipment, but also simplifies the transmission mechanism and reduces the failure rate.
