Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, specifically to an energy-saving ventilation device for building engineering. Background Technology

[0002] Building construction refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Ventilation systems must be installed in buildings during the design process. Building ventilation is divided into natural ventilation and mechanical ventilation. Its core function is to directly or after purification exhaust stale indoor air to the outside and replenish it with fresh air to ensure that the indoor air environment meets hygiene standards.

[0003] This measure aims to remove polluting gases from indoor or factory premises, ensure the thermal comfort of people indoors, and meet their need for fresh air.

[0004] Currently, the main energy-saving ventilation products used in the market are non-powered, naturally rotating ventilators installed on rooftops or factory roofs. However, these have many problems: they are easily damaged, have high wind resistance, and require frequent replacement of parts, leading to resource waste. Furthermore, their heat dissipation and exhaust effects are relatively slow. To address these issues, we have designed a new type of energy-saving ventilation device for building engineering. Utility Model Content

[0005] This utility model provides an energy-saving ventilation device for building engineering. By using ventilation components and shielding structures in combination, it can easily cope with rainy days, reduce the number of times parts need to be replaced, improve ventilation effect, and solve the problems mentioned in the background art of frequent parts replacement and poor heat dissipation and exhaust effect.

[0006] This utility model provides the following technical solution:

[0007] An energy-saving ventilation device for building engineering includes an outer shell, with an air outlet and an air inlet formed through the upper and lower parts of the shell. It also includes: a ventilation component disposed in the cavity of the outer shell, wherein the ventilation component is provided with an airflow channel connected to the air outlet and the air inlet, for causing the exhaust from the building to form a wind direction path along the airflow channel; and a shielding structure disposed at any position of the air outlet or the air inlet of the outer shell, the shielding structure including a shielding component and a guide component, for blocking rainwater and directing its flow.

[0008] As a preferred technical solution of this utility model, the ventilation component includes a frame plate fixedly connected to the cavity of the outer shell, the frame plate having a through hole, the through hole being connected to an air outlet and an air inlet, and the airflow channel being formed between the frame plate and the outer shell.

[0009] As a preferred technical solution of this utility model, the flow guide includes at least two sets of extension plates disposed at the bottom of the frame plate, the ends of the two sets of extension plates are joined together to form a liquid storage space, and a drain pipe connected to the liquid storage space is fixedly connected to the extension plate for directional drainage.

[0010] As a preferred technical solution of this utility model, the shielding member includes a first inclined plate and a second inclined plate fixedly connected to the top of the outer shell, the second inclined plate extending above the first inclined plate for rain protection.

[0011] As a preferred embodiment of this utility model, a limit rod is provided between the first inclined plate and the second inclined plate.

[0012] As a preferred technical solution of this utility model, the inner wall of the outer shell is provided with multiple sets of arc-shaped skeletons, and the multiple sets of arc-shaped skeletons are fixedly connected by connecting ribs.

[0013] Compared with the prior art, this utility model provides an energy-saving ventilation device for building engineering, which has the following beneficial effects:

[0014] 1. In this building energy-saving ventilation device, the outer shell and frame plate are used together to drive the directional flow of air in the building or factory through the chimney effect and based on the thermal pressure effect. The air enters the through hole along the indoor wind direction, which is the movement channel of the airflow. Finally, it is discharged into the outside air through the outlet wind direction, so that there is no need for frequent replacement, thus preventing waste of resources. At the same time, its heat dissipation and exhaust effect is also good, which can improve the indoor air quality.

[0015] 2. In the energy-saving ventilation device of this building project, the first inclined plate and the second inclined plate are used in combination to cope with rainy weather conditions;

[0016] 3. In the energy-saving ventilation device of this building project, two sets of symmetrical extension plates are set at the bottom of the frame plate, and the ends of the two sets of extension plates are joined to form a liquid storage space. When rainwater enters the shell through the air outlet, it can be intercepted by the extension plates and stored in the liquid storage space, and then directed to the outside of the shell through the drain pipe, thus dealing with rainy weather.

[0017] The parts not covered in this device are the same as or can be implemented using existing technologies. This utility model can effectively improve the ventilation efficiency of buildings, reduce energy consumption, eliminate the need for frequent replacement of parts, prevent resource waste, and at the same time, its heat dissipation and exhaust effects are also good, which can improve indoor air quality.

[0024] 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.

[0025] This utility model discloses an energy-saving ventilation device for building engineering, used to ventilate the air inside buildings or factories. Building engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipes, and equipment. Ventilation devices must be installed in buildings during the design process. Building ventilation is divided into natural ventilation and mechanical ventilation. Its core function is to directly or after purification exhaust polluted air from inside the building to the outside and replenish fresh air to ensure that the indoor air environment meets hygiene standards. This measure aims to remove polluted gases from indoor or factory premises, ensure the thermal comfort of indoor occupants, and meet their need for fresh air.

[0026] Example 1:

[0027] Reference Figure 1 , Figure 3 and Figure 4The device includes a housing 1 made of aluminum or steel as the base component, which is installed on a mounting groove on the roof of a building or factory to improve ventilation. The housing 1 is vertically continuous, and multiple sets of arc-shaped frames 101, such as four or six sets, are equidistantly arranged on the inner wall of the housing 1. The multiple sets of arc-shaped frames 101 are fixedly connected and combined by connecting ribs 102. The bottom of two adjacent sets of arc-shaped frames 101 are connected by limiting ribs 2 to form an air inlet, and the top of two adjacent sets of arc-shaped frames 101 forms an air outlet. The design of the arc-shaped frames 101 not only enhances the load-bearing capacity of the housing 1, but also allows air to flow along the inner wall of the housing 1. The connecting ribs 102 further strengthen the connection between the arc-shaped frames 101, ensuring the stability of the entire device in long-term use.

[0028] Specifically, a frame plate 3 is installed inside the cavity of the outer shell 1 via a connecting rib 102. A through hole 4 is provided on the frame plate 3, and a filter screen is installed on the through hole 4 to prevent flying animals from entering the air outlet. The through hole 4 is connected to both the air outlet and the air inlet, forming an airflow channel between the frame plate 3 and the outer shell 1. (Refer to...) Figure 3 This system utilizes the Bernoulli effect, where stronger outdoor winds result in faster exhaust speeds. By employing the chimney effect, based on the thermo-pressure effect—the temperature difference between the inside and outside of the chimney causes a difference in air density (high-temperature air is less dense, low-temperature air is more dense)—it drives the directional flow of air inside and outside the chimney. When a stove or boiler is operating, the generated hot air rises with the chimney and exits at the top. Through this principle, indoor gases can enter the through-hole 4 along the indoor wind direction, serving as a flow channel, and finally exit into the outside air through the outlet wind direction. This eliminates the need for frequent parts replacement, preventing resource waste, and also provides good heat dissipation and exhaust effects, improving indoor air quality.

[0029] To facilitate handling rainy weather, two sets of symmetrical extension plates are installed at the bottom of the frame plate 3, and the ends of the two sets of extension plates are joined to form a liquid storage space. A drain pipe 301 connected to the liquid storage space is fixedly connected to the extension plate for directional drainage. One end of the drain pipe 301 extends to the outside of the outer shell 1. When rainwater enters the outer shell 1 through the air outlet, it can be intercepted by the extension plate and stored in the liquid storage space, avoiding the erosion of the internal structure of the outer shell 1 by rainwater. As rainwater accumulates in the liquid storage space, the rainwater will be directionally drained to the outside of the outer shell 1 through the drain pipe 301, thereby ensuring that the ventilation device can operate normally in rainy weather and will not affect its ventilation effect due to water accumulation. This design not only improves the durability of the ventilation device, but also ensures its stability and reliability under various weather conditions.

[0030] Example 2:

[0031] Reference Figure 2Similar to Embodiment 1, this is mainly used to deal with rainy weather. A first inclined plate 6 and a second inclined plate 7 are provided on the top of the outer shell 1. The second inclined plate 7 extends above the first inclined plate 6 to block rainwater. At the bottom of the outer shell 1, that is, at the air inlet, two sets of symmetrical air diversion plates 5 are provided to guide the indoor airflow. The side walls of the air diversion plates 5 can also be fixed in the mounting groove opened in the roof. A limit rod 8 is provided between the first inclined plate 6 and the second inclined plate 7.

[0032] With this design, when rainwater drips onto the roof, it is first blocked by the second inclined plate 7 and slides down its slope to the first inclined plate 6, and is finally guided to the outside of the outer shell 1. This effectively prevents rainwater from directly entering the interior of the outer shell 1, i.e., the building interior. The setting of the diversion plate 5 not only enhances the guiding effect of indoor wind direction and ensures smooth airflow, but also improves the installation stability of the ventilation device through its side wall fixed in the installation groove. This design takes into account the special environmental needs of rainy days, ensuring the normal operation of the ventilation device in rainy days and improving its overall stability and durability.

[0033] It should be explained that in the event of severe weather, such as hail or heavy snow, simply block the air vents.

[0034] Components not described in detail in this article are existing technologies.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
