Description

Technical Field

[0001] This utility model relates to the field of factory ventilation technology, and in particular to a ventilation device that combines skylight and ventilator operation and an industrial plant. Background Technology

[0002] In industrial plants where thermal stress is significant, natural ventilation is a common method for removing excess heat. For some plants, the heat dissipation from process elements can reach nearly 200 W / m². 3 This is usually achieved with the help of skylights or vents. Because indoor air temperature is layered, the density difference between the upper and lower parts creates a thermal pressure difference, which causes hot air to rise; when the indoor pressure is higher than the outdoor pressure, the hot air is driven out by the pressure difference, thus achieving heat dissipation.

[0003] However, in actual industrial plants, the space available for ventilation facilities on the roof is often insufficient due to the combined effects of the building's floor plan dimensions, roof structure, and the layout of other professional pipelines. This results in ineffective heat dissipation, causing the internal temperature of some buildings to exceed the permissible limits for the workplace. Prolonged high temperatures not only affect working conditions but may also accelerate the aging of electrical wiring, creating potential safety hazards. Utility Model Content

[0028] The combined operation of the skylight and ventilator ventilation system 10 and the roof 20 are also included. Detailed Implementation

[0029] 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 based on this application are within the protection scope of the present utility model.

[0030] Figure 1 This is a schematic diagram of a skylight and ventilator combined operation ventilation device 10 installed on a roof 20, as provided in an embodiment of this application. Figure 1 As shown in the embodiment of this application, a ventilation device 10 combining a skylight and ventilators is proposed, comprising: a ventilation skylight 1 and several ventilators 2. The ventilation skylight 1 includes a skylight frame 11, a first side plate 12, a second side plate 13, and a light-transmitting panel 14. The first side plate 12, the second side plate 13, and the light-transmitting panel 14 are all disposed on the skylight frame 11. The bottom of the skylight frame 11 has an air inlet 15. The light-transmitting panel 14 is disposed above the air inlet 15. The first side plate 12 and the second side plate 13 are disposed on both sides of the light-transmitting panel 14, forming a first ventilation passage between the first side plate 12 and the first side of the light-transmitting panel 14. 16. A second ventilation passage 17 is formed between the second side panel 13 and the second side of the light-transmitting panel 14. An air outlet 18 is formed between the top of the first side panel 12 and the top of the second side panel 13. The air inlet 15, the first ventilation passage 16 and the air outlet 18 are connected in sequence. The air inlet 15, the second ventilation passage 17 and the air outlet 18 are connected in sequence. Several wind caps 2 are set on the first side panel 12 and the second side panel 13. The inlet of the wind cap 2 set on the first side panel 12 is connected to the first ventilation passage 16. The inlet of the wind cap 2 set on the second side panel 13 is connected to the second ventilation passage 17.

[0031] The skylight frame 11 serves as the overall support structure, with an air inlet 15 at its bottom for introducing hot indoor air into the skylight ventilator 10. A skylight panel 14 is positioned above the air inlet 15 to provide natural lighting. A first side panel 12 and a second side panel 13 are respectively positioned on either side of the skylight panel 14, forming independent first and second ventilation channels 16 and 17 to achieve dual-channel airflow distribution.

[0032] The first side panel 12 and the second side panel 13 are respectively disposed on both sides of the skylight panel 14. Their positions are configured according to the width and tilt angle of the skylight panel 14, thereby forming a first ventilation passage 16 between the first side panel 12 and the first side of the skylight panel 14, and a second ventilation passage 17 between the second side panel 13 and the second side of the skylight panel 14. The design of the two ventilation passages achieves balanced airflow distribution through symmetrical layout. Under the condition of increased indoor temperature and decreased air density, a stable air density difference is formed between indoors and outdoors, causing hot air to rise naturally and flow continuously from the lower space of the room to the roof 20, and then be exhausted to the outside by the ventilation device 10 in conjunction with the skylight vents. Among them, several vents 2 utilize the natural wind speed to drive the turbine rotation of the fan and the principle of indoor and outdoor air convection to accelerate and transform the parallel airflow into a vertical airflow from bottom to top, increasing the airflow speed (hot air exhaust) of the first ventilation passage 16 and the second ventilation passage 17, thereby improving the ventilation effect in the factory building.

[0033] Specifically, the first side plate 12 and the second side plate 13 both extend along the first direction, and a number of wind caps 2 are spaced apart along the first direction on the first side plate 12 and the second side plate 13.

[0034] The arrangement of several ventilators 2 along the first direction at intervals can be achieved by arranging them at equal intervals or by adjusting the interval distance according to ventilation requirements. The purpose is to optimize the coverage of the ventilators 2 and avoid the problem of insufficient local ventilation.

[0035] In the embodiments of this application, the type of hood 2 is not limited. For example, hood 2 can be a cylindrical hood, an umbrella-shaped hood, or a conical hood.

[0036] In specific implementation, the wind caps 2 include a first wind cap 21 and a second wind cap 22; the first wind cap 21 includes a first wind cap body 211 and a first sleeve 212, the first sleeve 212 connecting the first wind cap body 211 and the first side plate 12; the second wind cap 22 includes a second wind cap body 221 and a second sleeve 222, the second sleeve 222 connecting the second wind cap body 221 and the second side plate 13.

[0037] The first hood body 211 is a component used to guide airflow, ensuring that airflow can smoothly exit through the hood 2. The first sleeve 212 is an intermediate connector, which can be made of materials such as metal or plastic. The second hood body 221 is a component used to guide airflow, ensuring that airflow can smoothly exit through the hood 2. The second sleeve 222 is an intermediate connector, which can be made of materials such as metal or plastic.

[0038] The first hood body 211 is higher than the height of the first side plate 12, and the second hood body 221 is higher than the height of the second side plate 13.

[0039] During the operation of the first ventilator 21 and the second ventilator 22, since the second ventilator body 221 is higher than the second side plate 13, the influence of the first side plate 12 on the location of the first ventilator body 211 and the second side plate 13 on the location of the second ventilator body 221 is reduced. This is conducive to utilizing natural wind and indoor and outdoor temperature differences to form a local negative pressure zone around the air vents of the first ventilator body 211 and the second ventilator body 221, which significantly enhances the overall ventilation capacity of the skylight ventilator joint operation ventilation device 10.

[0040] This application further proposes that the combined ventilation device 10 for the skylight and ventilator also includes a valve assembly 3, which is openable and closable and located at the air inlet 15.

[0041] When valve assembly 3 is in the open state, air inlet 15 connects the room to the first ventilation passage 16, the room to the second ventilation passage 17. When valve assembly 3 is in the closed state, it cuts off the connection between air inlet 15 and the room.

[0042] The valve assembly 3 can be an electric valve assembly 3, which can be remotely controlled to open and close the valve assembly 3, allowing users to open or close the ventilation inlet according to actual needs.

[0043] For example, closing valve assembly 3 in rainy or cold weather can effectively prevent rainwater from entering the room and protect the equipment from damage; when ventilation is not required, closing valve assembly 3 can also reduce heat loss and save energy. When the indoor temperature is high, opening valve assembly 3 can ventilate and dissipate heat.

[0044] Specifically, both the first side plate 12 and the second side plate 13 are made of profiled steel sheet and are semi-annular in shape. The embodiments of this application do not limit the thickness of the profiled steel sheet; for example, it can be 0.6 mm.

[0045] The semi-circular geometric design not only enhances the structural strength of the side plate, but also optimizes the streamlined path of the airflow in the first ventilation passage 16 and the second ventilation passage 17, thereby improving ventilation efficiency.

[0046] Specifically, the first sleeve 212 of the first vent 21 is located in the upper half of the semi-annular first side plate 12, and the second sleeve 222 of the second vent 22 is located in the upper half of the semi-annular second side plate 13. Guided by the upper half of the semi-annular first side plate 12, the airflow passes through the arc-shaped guide between the upper and lower halves of the semi-annular first side plate 12 before entering the first vent 21, which helps improve the exhaust effect of the first vent 21. Guided by the upper half of the semi-annular second side plate 13, the airflow passes through the arc-shaped guide between the upper and lower halves of the semi-annular second side plate 13 before entering the second vent 22, which helps improve the exhaust effect of the second vent 22.

[0047] During implementation, the two sides of the skylight panel 14 are tilted downwards; drainage components 4 are installed at the bottom of both sides of the skylight panel 14.

[0048] The skylight panel 14 can be made of transparent or semi-transparent material to accommodate lighting. The downward-sloping design of the skylight panel 14 allows rainwater or condensation to flow naturally along the sloping surface to the bottom sides, reducing water accumulation on the surface. The drainage component 4 can be a drainage channel, drain pipe, or other structure with a flow guiding function, designed to collect and guide water out, preventing leakage or water accumulation from corroding the device or affecting ventilation performance.

[0049] Specifically, along the height direction of the ventilation skylight 1, the projection of the first side panel 12 overlaps with the projection of the first side of the light-transmitting panel 14, and the projection of the second side panel 13 overlaps with the projection of the second side of the light-transmitting panel 14.

[0050] Specifically, the above technical solution forms a continuous barrier structure by overlapping the projected portions of the first side panel 12 and the first side of the light-transmitting panel 14 in the height direction of the ventilation skylight 1, and by overlapping the projected portions of the second side panel 13 and the second side of the light-transmitting panel 14. This barrier structure can effectively reduce rainwater seepage into the ventilation passage through the gaps between the first side panel 12, the second side panel 13, and the light-transmitting panel 14, while maintaining sufficient ventilation gaps to ensure smooth airflow.

[0051] The embodiments of this application further propose that the combined ventilation device 10 for the sunroof and ventilator also includes a first guide plate 5 and a second guide plate 6. The first guide plate 5 is disposed in the first ventilation passage 16 and extends along the airflow direction of the first ventilation passage 16; the second guide plate 6 is disposed in the second ventilation passage 17 and extends along the airflow direction of the second ventilation passage 17.

[0052] Specifically, the first deflector plate 5 and the second deflector plate 6 can be made of thin metal sheets, plastic molded parts, or other materials with appropriate strength and weather resistance.

[0053] The first guide plate 5 is disposed in the first ventilation passage 16 and extends along the airflow direction, which can effectively reduce the resistance and turbulence of the airflow during the flow of the air in the first ventilation passage 16. The second guide plate 6 is disposed in the second ventilation passage 17 and extends along the airflow direction, which can effectively reduce the resistance and turbulence of the airflow during the flow of the air in the second ventilation passage 17, thereby improving ventilation efficiency and providing a more reliable natural ventilation solution for industrial plants.

[0054] This application also proposes an industrial plant, which includes a roof 20 and a combined ventilation device 10 for skylights and ventilators as described in the above embodiment. The skylight frame 11 is installed on the roof 20, and the air inlet 15 is connected to the interior of the industrial plant.

[0055] The ventilation principle of the industrial plant in this application is as follows:

[0056] By integrating the skylight and vent 2 to form a dual-channel coordinated ventilation system, the airflow path is optimized and the problem of insufficient roof space leading to ineffective heat dissipation is solved. An air inlet 15 is located at the bottom of the skylight frame 11, utilizing thermal pressure difference to drive indoor hot air to be efficiently drawn in from the bottom and rise along the supporting structure of the skylight frame 11. A skylight panel 14 is positioned above the air inlet 15, providing natural lighting while avoiding obstruction of the airflow inlet, ensuring smooth airflow. A first side panel 12 and a second side panel 13 are respectively positioned on both sides of the skylight panel 14, thus forming a first ventilation passage 16 between the first side panel 12 and the first side of the skylight panel 14, and a second ventilation passage 17 between the second side panel 13 and the second side of the skylight panel 14. The symmetrical layout of the two ventilation passages achieves balanced airflow distribution. An air outlet 18 is located between the tops of the first side panel 12 and the second side panel 13 (above the skylight panel 14), where high-temperature airflow is concentrated and discharged at the top. Air inlet 15, first ventilation passage 16, and air outlet 18 are sequentially connected, as are air inlet 15, second ventilation passage 17, and air outlet 18. A continuous flow path is constructed based on the natural upward flow law of airflow, ensuring the smooth discharge of hot air from bottom to top. Several ventilators 2 are disposed on the first side plate 12 and the second side plate 13. The inlet of the ventilator 2 disposed on the first side plate 12 is connected to the first ventilation passage 16, and the inlet of the ventilator 2 disposed on the second side plate 13 is connected to the second ventilation passage 17. These ventilators 2 serve as auxiliary outlets for natural exhaust, effectively utilizing outdoor wind pressure to create a local negative pressure zone around the vents, significantly enhancing the overall exhaust capacity of the skylight-ventilator combined ventilation device 10. The structure of these ventilators 2 ensures that the exhaust outlets of the ventilators 2 are within the negative pressure range, effectively overcoming system resistance. The ventilation skylight 1 and the ventilator 2 work together to save space occupied by the roof 20 while improving the efficiency of natural ventilation, which helps to maintain the indoor temperature within the set range, significantly alleviates the problem of overheating inside industrial plants under high summer temperatures, and improves the quality of the indoor thermal environment.

[0057] The skylight-ventilation hood combined with ventilation system 10 proposed in this application can efficiently remove indoor waste heat, helping to prevent the internal temperature of the station building from exceeding the permissible limit for the workplace and avoiding safety hazards such as accelerated aging of electrical circuits and abnormal operation of process equipment caused by long-term high temperatures. This skylight-ventilation hood combined with ventilation system 10 saves roof space while reducing the probability of spatial conflicts with other specialized equipment, thereby improving the rationality and coordination of the overall design. Furthermore, its efficient natural ventilation capacity also helps reduce mechanical ventilation energy consumption and save operating costs.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
