Description

Technical Field

[0001] The invention relates to the field of buildings, and in particular to a building air duct gas control device. Background Art

[0002] In recent years, with the development of green building, the development of low-carbon and energy-saving technologies has become an important issue in the field of construction, and the use of innovative technologies for energy conservation and emission reduction has become an urgent issue. The shading system on the building facade can not only save energy but also enrich the light distribution indoors. At the same time, it is closely integrated with the outside air and has a large area, and has a high potential in air carbon capture.

[0003] Carbon capture technology is a technology that captures carbon dioxide from the air. It is an important part of the carbon capture system. The carbon capture system includes air collection, treatment, and storage processes, which can process and recycle carbon dioxide in the air. At present, carbon capture systems are mainly used in the form of large and medium-sized equipment in high places outdoors in industrial plants or on building roofs. However, in densely populated urban areas or areas with environmental pollution, such large equipment requires a large space area, while urban sites and building roofs are often small in area and inconsistent with the urban architectural style, making it difficult to deploy carbon capture technology in urban buildings.

[0004] Therefore, in actual engineering practice, the air ducts and components of urban building curtain walls are studied:

[0005] 1. Carbon capture technology in the existing technology uses an air pump to suck air through a pipeline for processing. There may be gas control equipment in the pipeline. However, when faced with a complex and changeable gas environment, such as the external wind force is different, or some pipelines are close to the air pump / exhaust fan and some are far away; these factors combined will cause the local wind force to be too strong and produce wind whistles. However, there is no low-cost and effective solution to control and adjust.

[0006] 2. The gas control equipment in the prior art is arranged on the main gas pipeline. However, when the bend of the pipeline faces a strong airflow, the gas directly moves in the main pipeline, which will cause a large local wind impact and cause pipeline vibration.

[0007] 3. The non-powered, automatic gas control devices in the prior art have relatively simple functions. For example, a one-way piston or a one-way valve can realize one function by controlling the one-way closure of the fluid, but there is no automatic gas control device that can realize three functions.

[0008] Fourth, the wind speed sensor of the prior art requires a separate space for installation. If it is placed at the main axis position, it will interfere with the main functional components.

[0009] 5. The travel limits in the prior art are all complete limits, without a semi-limit state or an incomplete limit state. Summary of the invention

[0010] In order to overcome the above problems, the present invention proposes a solution to solve the above multiple problems at the same time.

[0011] The technical solution adopted by the present invention to solve the technical problem is: a building air duct gas control device, including a main body, a first piston, a second piston, a cylinder, a retaining cylinder, a support frame, a wind speed sensor, an annular seat ring, a support plate, and a blocking rod; the main body includes an upper section, a lower section, an air inlet, and an air outlet; the first piston includes an upper rod, a circular ring plate, a disc, a lower rod, and a support rod; the wind speed sensor includes a sensor main body and an impeller; the second piston includes a piston disc, a cylinder plate, and a sliding rod; the cylinder is provided with an air vent, a lower air outlet, an upper air outlet, a slide groove, and a groove;

[0012] The main body is arranged on a bottom plate, a circular hole is arranged on the bottom plate, a circular plate is arranged in the middle of the circular hole, the circular plate and the bottom plate are connected by a frame rod, the sensor main body is arranged on the circular plate, the impeller is arranged on the outer wall of the sensor main body, a support plate is arranged above the sensor main body, and an annular seat ring is arranged above the support plate; the inner wall diameter of the upper section is larger than the inner wall diameter of the lower section, the upper section and the lower section are both cylindrical, a support frame is arranged on the upper part of the inner wall of the lower section, the retaining cylinder is arranged in the middle part of the support frame, the retaining cylinder is used to retain the lower rod, the upper part of the support frame supports the cylinder, the upper end of the cylinder is connected below the top wall of the upper section, the outer wall diameter of the cylinder is equal to the inner wall diameter of the lower section, so as to form a cavity between the outer wall of the cylinder and the inner wall of the upper section;

[0013] The first and second pistons can both move up and down in the cylinder, and the upper rod and the annular plate are arranged above the disc, and the lower rod is arranged below, and the support rod is arranged below the lower rod, and the support rod can be moved to abut or leave the supporting plate; the lower end of the lower section is provided with an air inlet, and the upper end of the upper section is provided with an air outlet, and the air vent is always connected to the inside of the cylinder and the cavity; when the support rod abuts against the supporting plate, the annular plate blocks the lower air port, and the first piston can move upward under the action of air pressure so that the upper end of the annular plate contacts the baffle rod, thereby making the lower air port fully open; when the first piston continues to move upward under the action of air pressure, the annular plate pushes the baffle rod away so that the baffle rod enters the groove of the inner wall of the cylinder, and then the first piston moves so that the upper rod abuts against the piston disc and pushes the piston disc upward, thereby making the cylinder plate arranged above the piston disc move up to gradually close the upper air port, and the outer edge of the piston disc is provided with the sliding rod, and the inner wall of the cylinder is provided with a sliding groove, and the sliding rod can move in the sliding groove.

[0014] Preferably, the slide groove does not penetrate the cylindrical wall.

[0015] Preferably, in the cylinder, the upper air inlet is located above the slide groove, and the number of the upper air inlets is two.

[0016] Preferably, in the cylinder, the slide groove is located above the groove, and the number of the slide rods is four.

[0017] Preferably, in the cylinder, the groove is located above the lower air port, and the number of the grooves is four.

[0018] Preferably, in the cylinder, the lower air inlet is located above the air holes, the number of the lower air inlets is two, and the number of the air holes is four.

[0019] Preferably, the blocking rod is pivotally connected to the inner wall of the cylinder.

[0020] Preferably, the blocking rod provides the return force and the blocking force by means of a torsion spring.

[0021] Preferably, the length of the upper section is greater than the length of the lower section.

[0022] Preferably, a step transition is formed between the upper section and the lower section.

[0023] The beneficial effects of the present invention are:

[0024] 1. In response to the first point raised in the background technology, an automatic gas control device without a power source is set up, which can maintain a ventilated state when the exhaust fan / air pump is stopped, maintain a large flow state when it is turned on and working normally, and automatically reduce the flow when the wind force is too strong.

[0025] 2. Regarding the second point raised in the background technology, the main body of the gas control device is divided into two sections with different diameters. The lower section constitutes the main air path, and the upper section diverts the main air path and then leads it back, thus constructing a curved path. At the same time, the first and second pistons convert the impact force into displacement. Both schemes provide airflow buffering.

[0026] 3. Regarding the third point raised in the background technology, two power-free pistons are used to adjust the openings of two groups of air outlets. At the same time, there are normally open air holes to keep air permeable at all times. Through a simple structure, three working states are achieved without a power source.

[0027] 4. In response to the fourth point raised in the background technology, the wind speed sensor is arranged on the axis of the main space, and there is no need to arrange a separate additional space for accommodating the wind speed sensor. At the same time, a bracket is arranged on the upper part of the wind speed sensor to receive the main functional components, thereby avoiding interference with the main functional components.

[0028] 5. In response to the fifth point raised in the background technology, a torsion spring torsion barrier rod is provided, which can block the lifting of the piston when the wind force is within a certain limit, and can push the barrier rod to move upward when the wind force exceeds a certain limit.

[0029] Note: The above designs are not listed in any particular order, and each one makes the present invention distinctive and significantly advanced compared to the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
