Description

Technical Field

[0001] The present application relates to the technical field of ventilation equipment for steel structure workshops, and in particular to a ventilation structure for steel structure workshops. Background Art

[0002] A steel structure factory building primarily refers to a building whose primary load-bearing components are made of steel. This includes steel columns, steel beams, steel foundations, steel roof trusses, and steel roofs. Steel walls can also be enclosed with brick walls. Due to the increase in steel production in my country, many new factories have begun to utilize steel structures, which can be categorized as light or heavy steel structures.

[0003] To ensure better ventilation and optimize the working environment within steel structure workshops, ventilation structures are usually installed on the steel structure workshops. Existing ventilation structures usually include ventilation pipes and ventilation devices. The ventilation pipes connect the interior of the steel structure workshop with the outside world, and the ventilation devices are fixedly installed inside the steel structure workshop to drive the air circulation between the interior and the outside world.

[0004] However, in the existing ventilation structure, it is difficult for the outside wind to directly enter the interior of the steel structure factory through the ventilation pipe to circulate the air, and the ventilation device is installed on the steel structure. When the ventilation device is working, the vibration will collide with the steel structure at high frequency to produce a large noise, and the noise pollution caused is relatively large. Summary of the Invention

[0005] In order to improve the problem of significant noise pollution caused by existing ventilation structures, the present application provides a steel structure factory ventilation structure.

[0006] This application provides a ventilation structure for a steel structure factory building, which adopts the following technical solutions:

[0007] A ventilation structure for a steel structure factory building includes a first ventilation duct, a second ventilation duct and a ventilation device, wherein the first ventilation duct runs through the steel structure factory building, the second ventilation duct is arranged on one side of the steel structure factory building, and the two ends of the first ventilation duct are respectively connected to the interior of the steel structure factory building and the second ventilation duct; one end of the second ventilation duct is open, and the ventilation device is arranged inside the second ventilation duct and located at the end of the second ventilation duct away from the opening thereof; and further includes a plurality of vibration dampers, the two ends of the vibration dampers are respectively connected to the second ventilation duct and the steel structure factory building, and the vibration dampers are located between the second ventilation duct and the steel structure factory building.

[0008] By adopting the above technical solution, when the ventilation device is working, the outside air can enter the interior of the steel structure factory building along the second ventilation duct and the first ventilation duct in turn; the vibration damping component can absorb part of the vibration generated when the ventilation device is working, thereby reducing the noise generated by the vibration of the ventilation device colliding with the steel structure; and the ventilation device is installed on the outside of the steel structure factory building, which can reduce the impact of the noise generated by the operation of the ventilation device on the interior of the steel structure factory building, and the impact of noise in open places will also be reduced.

[0009] Optionally, it also includes an air duct, the axis of the second ventilation duct is vertical, the ventilation direction of the air duct is horizontal and the duct is rotatably connected to the second ventilation duct, the rotation axis of the air duct is parallel to the axis of the second ventilation duct, and the air duct is communicated with the second ventilation duct; it also includes a driving component, the driving component is fixedly arranged above the air duct, and the driving component controls the rotation of the air duct with the help of wind force, so that the ventilation direction of the air duct is parallel to the wind direction.

[0010] By adopting the above technical solution, the driving component can use the wind force and control the rotation of the induced draft duct according to the wind direction, so that the induced draft duct keeps its own axis parallel to the wind direction, making it convenient for the natural wind from the outside to directly enter the interior of the steel structure factory through the induced draft duct, the second ventilation duct and the first ventilation duct in sequence, thereby reducing the frequency of use of the ventilation device or reducing the working power of the ventilation device, thereby reducing the probability of a large impact of noise pollution generated during the use of the ventilation structure.

[0011] Optionally, the driving assembly includes a first pneumatic plate, which is fixedly connected to the air duct, the plane where the first pneumatic plate is located is parallel to the ventilation direction of the air duct, and the connection position between the first pneumatic plate and the air duct is located at one end of the first pneumatic plate in the horizontal direction.

[0012] By adopting the above-mentioned technical solution, when the natural wind from the outside blows onto the first pneumatic plate, it can push the first pneumatic plate to drive the draft duct to rotate. The natural wind from the outside will push the first pneumatic plate to move to a plane where the first pneumatic plate is located and is parallel to the direction of the natural wind, so that the ventilation direction of the draft duct is parallel to the direction of the natural wind; the first pneumatic plate enables the draft duct to rotate and adjust its position according to the natural wind in different directions, thereby facilitating the natural wind from different directions to blow into the draft duct, reducing the situation where the natural wind cannot enter the draft duct due to the wind direction problem of the natural wind.

[0013] Optionally, the driving assembly includes a second pneumatic plate, which is fixedly connected to the air duct, the plane where the second pneumatic plate is located is perpendicular to the ventilation direction of the air duct, and the vertical center line of the second pneumatic plate coincides with the rotation axis of the air duct.

[0014] By adopting the above technical solution, when the natural wind from the outside blows onto the second pneumatic plate, it can push the second pneumatic plate to drive the draft duct to rotate. The natural wind from the outside will push the second pneumatic plate to move to its own plane which is perpendicular to the direction of the natural wind. At this time, the two ends of the second pneumatic plate are affected by the force of the natural wind and tend to be balanced, so that the second pneumatic plate can maintain its position, so that the ventilation direction of the draft duct can remain parallel to the direction of the natural wind; the second pneumatic plate enables the draft duct to rotate and adjust its position according to the natural wind in different directions, so as to facilitate the natural wind from different directions to blow into the draft duct, reducing the situation where the natural wind cannot enter the draft duct due to the wind direction problem of the natural wind.

[0015] Optionally, the driving assembly further includes a plurality of pneumatic impellers, which are disposed on the second pneumatic plate. The plurality of pneumatic impellers are symmetrically distributed along the vertical center line of the second pneumatic plate, and the pneumatic impellers rotate to provide power to the ventilation device.

[0016] By adopting the above technical solution, when the natural wind from the outside blows onto the second pneumatic plate, it can not only push the second pneumatic plate to drive the draft duct to rotate, but also drive the pneumatic impeller to rotate; the rotation of the pneumatic impeller can reduce the pushing effect of the natural wind on the second pneumatic plate, so that the second pneumatic plate can slow down the speed of rotation of the draft duct with the help of wind force, thereby making the process of adjusting the draft duct according to the wind direction more stable, reducing the probability of frequent rotation of the draft duct due to the unbalanced force of the natural wind on the second pneumatic plate, and further increasing the probability that the ventilation direction of the draft duct remains parallel to the natural wind direction; and, the rotation of the pneumatic impeller can generate electricity to power the ventilation device, thereby saving the energy required for the ventilation device and being more green and environmentally friendly.

[0017] Optionally, the air duct is open in two directions along its own axial direction, and a guide member is provided inside the air duct. The guide member has a guide surface at one end close to the air duct opening, and the guide surface guides the wind to move into the second ventilation duct.

[0018] By adopting the above technical solution, both end openings of the induced draft duct can allow natural wind to blow in, thereby improving the fault tolerance of the driving component in controlling the induced draft duct to rotate with the help of wind force and according to the wind direction until the axis is parallel to the direction of natural wind; and, after the natural wind blows in from one end opening of the induced draft duct, it can change the blowing direction along the guide surface and enter the second ventilation duct, thereby reducing the probability of natural wind blowing in from one end opening of the induced draft duct and then leaving from the other end opening, increasing the probability that natural wind can eventually enter the interior of the steel structure factory building after blowing into the induced draft duct, and reducing the wind speed loss of natural wind during the blowing process, thereby ensuring the effect of air circulation.

[0019] Optionally, it also includes two rotating plates and two elastic members, wherein the rotating plate is located inside the air duct and the two rotating plates are respectively located on both sides of the guide member; one end of the rotating plate is rotatably connected to the air duct, and the rotating axis of the rotating plate is perpendicular to the ventilation direction of the air duct; the elastic member drives the rotating plate to maintain an inwardly inclined state, and when the rotating plate rotates to the extreme position in the direction away from the guide member, the rotating plate closes the opening at one end of the air duct.

[0020] By adopting the above technical solution, when natural wind blows in from the opening at one end of the draft duct, if the natural wind force is relatively small, the natural wind can enter from the space between the rotating plate and the wall of the draft duct cavity and enter the second ventilation duct along the guide surface; if the natural wind force is relatively large, the natural wind can push both rotating plates to overcome the action of the elastic member to rotate, so that the space between the rotating plate at the end where the natural wind enters and the wall of the draft duct cavity is expanded, and the rotating plate at the other end closes the opening at the other end of the draft duct, further reducing the probability of natural wind blowing in from the opening at one end of the draft duct and then leaving from the opening at the other end, so that more natural wind can enter the interior of the steel structure factory through the draft duct.

[0021] Optionally, a synchronization component is further included, which synchronizes the rotation of the two rotating plates, and the inclination angle of the rotating plates is 45°.

[0022] By adopting the above technical solution, after natural wind blows into the air duct, the natural wind drives one rotating plate to rotate while driving the other rotating plate to rotate synchronously, so that the process of rotating the rotating plate with the help of wind force is more labor-saving, and the loss of wind force in the process of natural wind driving the rotating plate to rotate is reduced; at the same time, it is convenient for natural wind to blow in, so that one rotating plate is rotated to the state where the opening at one end of the air duct is fully opened, and the other rotating plate is rotated to the state where the opening at the other end of the air duct is closed.

[0023] Optionally, it also includes a sensing member for sensing rainwater and a locking assembly for limiting the rotation of the rotating plate, and the sensing member is signal-connected to the locking assembly; when the elastic member drives the rotating plate to maintain an inclined state, the end of the rotating plate close to the guide member is the inclined upper end.

[0024] By adopting the above technical solution, in rainy weather, the sensor will be triggered and control the locking assembly to lock the two rotating plates in a fixed position, so that the two rotating plates can still maintain an inclined state under the push of natural wind. After rainwater enters the air duct with natural wind or with wind when the ventilation device is working, the rotating plates can intercept the rainwater, and after being intercepted, the rainwater will flow out of the air duct along the tilt direction of the rotating plates, thereby reducing the probability of rainwater entering the second ventilation duct.

[0025] In summary, this application has at least one of the following beneficial effects:

[0026] 1. It can reduce the intensity of vibration when the ventilation device is working, thereby reducing the noise generated when the ventilation device is working, and can reduce the impact degree and impact range of the noise generated when the ventilation device is working;

[0027] 2. It can greatly improve the utilization rate of natural wind, thereby reducing the use frequency of ventilation devices or reducing the working power of ventilation devices, and further reducing the impact of noise generated by the operation of ventilation devices;

[0028] 3. The ventilation structure can adjust its own state according to the direction of the natural wind, so that natural wind from different directions can be utilized, further improving the utilization rate of the ventilation structure for natural wind. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] Example 1:

[0036] Reference Figure 1 and Figure 2, the embodiment of the present application discloses a steel structure factory ventilation structure, which is installed on the steel structure factory 1, and includes a first ventilation duct 2, a second ventilation duct 3, a ventilation device 4, an induced draft duct 5 and a drive assembly 6. The first ventilation duct 2 and the second ventilation duct 3 are both fixedly installed on the steel structure factory 1, and the induced draft duct 5 is rotatably connected to the second ventilation duct 3. The drive assembly 6 is installed on the induced draft duct 5 and is used to control the rotation of the induced draft duct 5 with the help of wind force and according to the wind direction, so that natural wind can blow into the induced draft duct 5 and pass through the second ventilation duct 3 and the first ventilation duct 2 in turn into the interior of the steel structure factory 1, thereby realizing air circulation between the interior of the steel structure factory 1 and the outside world. In this embodiment, it is preferred that the first ventilation duct 2 and the second ventilation duct 3 are both circular tubes, and the induced draft duct 5 is preferably a square tube.

[0037] After the first ventilation duct 2 is fixedly installed on the steel structure factory building 1, the axis of the first ventilation duct 2 is horizontal, and the two ends of the axis of the first ventilation duct 2 are respectively in communication with the interior of the steel structure factory building 1 and the outside. After the second ventilation duct 3 is fixedly installed on the steel structure factory building 1, the second ventilation duct 3 is fixedly connected to the first ventilation duct 2, the axis of the second ventilation duct 3 is vertical, and the two ends of the second ventilation axis are respectively in communication with the first ventilation duct 2 and the outside; the end of the second ventilation duct 3 close to the first ventilation duct 2 is closed, and the ventilation device 4 is fixedly installed inside the second ventilation duct 3 and is located at the end of the second ventilation duct 3 close to the first ventilation duct 2. In this embodiment, the ventilation device 4 is preferably a fan. Since the fan is a common existing technology in this field, it will not be described here.

[0038] The ventilation structure also includes several filter plates 102 for filtering impurities in the air. After the ventilation device 4 is fixedly installed in the second ventilation pipe 3, the ventilation device 4 is located below the position where the first ventilation pipe 2 and the second ventilation pipe 3 are connected. A filter plate 102 is detachably installed in the second ventilation pipe 3, and the filter plate 102 is located above the ventilation device 4.

[0039] The ventilation structure also includes a support member 11 and several vibration dampers 101. The support member 11 is located outside the steel structure building 1 and is fixedly connected to the steel structure building 1. The support member 11 is located below the second ventilation duct 3. The vibration dampers 101 are located between the second ventilation duct 3 and the steel structure building 1, and between the second ventilation duct 3 and the support member 11. The ends of the vibration dampers 101 are respectively fixedly connected to the second ventilation duct 3 and the steel structure building 1, or respectively to the second ventilation duct 3 and the support member 11. In this embodiment, the vibration dampers 101 are preferably damping springs that can absorb some of the vibrations generated during operation of the ventilation device 4.

[0040] One side of the induced draft duct 5 has a rotating base 52, which fits over the end of the second ventilation duct 3 away from the ventilation device 4. The induced draft duct 5 is rotatably connected to the second ventilation duct 3 via the rotating base 52. The induced draft duct 5 communicates with the second ventilation duct 3, and the rotation axis of the induced draft duct 5 coincides with the axis of the second ventilation duct 3. Both ends of the induced draft duct 5 are open along its length, and the rotating base 52 is located midway along the length of the induced draft duct 5. A filter plate 102 is also detachably connected to the induced draft duct at the location of the rotating base 52.

[0041] The interior of the duct 5 is equipped with a guide member 51 for directing airflow. This member is located at the top of the duct 5 and is aligned with the rotating base 52 along the duct's rotational axis. Each end of the guide member 51, near the two openings on the duct 5, has a curved guide surface 511. When outside air enters through one opening along the length of the duct 5, it comes into contact with the guide surface 511, directing the air vertically downward into the second vent pipe.

[0042] Reference Figure 2 and Figure 3 The ventilation structure also includes two rotating plates 7 and two elastic members 103. The rotating plates 7 are installed inside the draft duct 5, and the two rotating plates 7 are respectively located at the two ends of the axial direction of the draft duct 5 and on both sides of the guide member 51. The bottom of the rotating plate 7 is rotatably connected to the bottom cavity wall of the draft duct 5, and the rotation axis of the rotating plate 7 is horizontal and perpendicular to the length direction of the draft duct 5. The two elastic members 103 are respectively installed at the rotation connection positions of the two rotating plates 7 and the draft duct 5. The elastic members 103 drive the rotating plates 7 to maintain an inclined state. At this time, the acute angle between the plane where the rotating plates 7 are located and the length direction of the draft duct 5 is 45°, and the end of the rotating plate 7 close to the guide member 51 is the inclined upper end. In this embodiment, the elastic member 103 is preferably a torsion spring.

[0043] There are limitations on the rotation of the rotating plate 7. When the rotating plate 7 rotates to the extreme position in the direction close to the guide member 51, the plane where the rotating plate 7 is located is horizontal, and the rotating plate 7 is in contact with the cavity wall at the bottom of the air duct 5; when the rotating plate 7 rotates to the extreme position in the direction away from the guide member 51, the end of the rotating plate 7 away from the elastic member 103 is in contact with the cavity wall at the top of the air duct 5, and the rotating plate 7 closes the opening at its own end on the air duct 5.

[0044] The ventilation structure also includes a synchronization assembly 9 for causing the two rotating plates 7 to rotate synchronously. The synchronization assembly 9 is fixedly mounted on the draft duct 5. In this embodiment, the synchronization assembly 9 is preferably a chain, and the two rotating plates 7 preferably have a gear structure at the rotational connection position. The chain is simultaneously engaged with the two gear structures, thereby causing the two rotating plates 7 to rotate in the same direction and synchronously. In turn, under the action of wind, the two rotating plates 7 can present a phenomenon in which one rotating plate 7 closes the opening at one end of the draft duct 5 and the other rotating plate 7 abuts against the bottom cavity wall of the draft duct 5. In other embodiments, the synchronization assembly 9 can also be a synchronous belt.

[0045] The ventilation structure also includes a sensor 104 for sensing rain and a locking assembly 8 for limiting the rotation of the two rotating plates 7. The sensor 104 is fixedly mounted on the top of the draft duct 5. The locking assembly 8 restricts the rotation of one rotating plate 7, thereby limiting the rotation of both rotating plates 7. The sensor 104 and the locking assembly 8 are signal-connected. When the sensor 104 is triggered by rain, the locking assembly 8 activates to restrict the rotation of the first rotating plate 7. Rainwater entering the draft duct 5 with the airflow is intercepted by the tilted rotating plate 7 and slides outward along the tilted surface of the rotating plate 7, leaving the draft duct 5. In this embodiment, since the sensor 104 for sensing rain is common in the prior art, it will not be described in detail here.

[0046] Reference Figure 3 The locking assembly 8 includes a driving member 81 and a locking member 82. The driving member 81 is fixedly mounted on the outside of the air duct 5 and is located below the rotational connection position between a rotating plate 7 and the air duct 5. The locking member 82 is fixedly connected to the driving member 81. The driving member 81 controls the locking member 82 to enter and exit the air duct 5. The end of the rotating plate 7 close to its own rotational connection position is provided with a locking groove 71 for the locking member 82 to be inserted. When the rotating plate 7 is kept in an inclined state under the action of the elastic member 103, the driving member 81 drives the locking member 82 to move in the direction close to the rotating plate 7, and the locking member 82 can be inserted into the locking groove 71. At this time, the rotation of the rotating plate 7 is restricted. In this embodiment, the driving member 81 is preferably a servo motor, and the driving member 81 preferably controls the movement of the locking member 82 by means of a screw drive. Since the screw drive is a common existing technology, it will not be described in detail here, and the screw drive structure is omitted in the accompanying drawings.

[0047] Reference Figure 1 and Figure 2The drive assembly 6 is mounted on the top of the draft duct 5 and includes a first pneumatic plate 61 and a connector 62. One end of the connector 62 is fixedly connected to the top of the draft duct 5, and the centerline of the connector 62 is vertical and coincides with the rotation axis of the draft duct 5. The first pneumatic plate 61 is a rectangular plate-shaped structure, with one width side of the first pneumatic plate 61 fixedly connected to the connector 62. The rotation axis of the draft duct 5 is located in the plane where the first pneumatic plate 61 is located, and the length direction of the first pneumatic plate 61 is parallel to the length direction of the draft duct 5. When natural wind blows against the first pneumatic plate 61, it pushes the first pneumatic plate 61 to move so that the plane where the first pneumatic plate 61 is located is parallel to the wind direction of the natural wind, thereby making the length direction of the draft duct 5, i.e., the ventilation direction, parallel to the wind direction of the natural wind.

[0048] The implementation principle of the ventilation structure of a steel structure factory building in the embodiment of the present application is as follows:

[0049] The natural wind outside the steel structure workshop 1 can blow onto the first wind moving plate 61, pushing the first wind moving plate 61 to move, ultimately making the ventilation direction of the induced draft duct 5 parallel to the direction of the natural wind. The natural wind can then push the rotating plate 7 to rotate, expanding the space for the natural wind to enter the induced draft duct 5. The natural wind then enters the induced draft duct 5 and, guided by the guide member 51, enters the second ventilation pipe, and finally enters the interior of the steel structure workshop 1 through the first ventilation pipe.

[0050] When it rains, the natural wind can still blow onto the first pneumatic plate 61, pushing it to move, ultimately making the ventilation direction of the air duct 5 parallel to the direction of the natural wind. At the same time, the sensor 104, when triggered by the rain, controls the locking assembly 8 to limit the rotation of the two rotating plates 7, so that the rotating plates 7 can intercept rainwater without affecting the natural wind from entering the air duct 5.

[0051] When there is less natural wind, the ventilation device 4 is controlled to start. Part of the vibration generated during the operation of the ventilation device 4 will be absorbed by the vibration-damping parts 101, thereby reducing the noise generated by the vibration of the ventilation device 4; and the noise generated by the ventilation device 4 has little impact on the outside world.

[0052] Example 2:

[0053] Reference Figure 1 and Figure 4 The difference between this embodiment and embodiment 1 lies in the driving assembly 6 , which includes a second pneumatic plate 63 and a plurality of pneumatic impellers 64 .

[0054] Reference Figure 4 The second pneumatic plate 63 is a rectangular plate structure. The second pneumatic plate 63 is fixedly connected to the top of the air duct 5. The plane where the second pneumatic plate 63 is located is perpendicular to the length direction of the air duct 5, and the vertical center line of the second pneumatic plate 63 coincides with the rotation axis of the air duct 5.

[0055] The plurality of pneumatic impellers 64 are rotatably mounted on the second pneumatic plate 63 , with the rotation axis of the pneumatic impellers 64 parallel to the length direction of the duct 5 , and the installation positions of the plurality of pneumatic impellers 64 on the second pneumatic plate 63 are symmetrically distributed along the vertical center line of the second pneumatic plate 63 .

[0056] The wind force required for the wind impeller 64 to rotate is smaller than the wind force required for the second wind plate 63 to move. When the natural wind blows onto the second wind plate 63, it first rotates the wind impeller 64 and then drives the second wind plate 63 to move.

[0057] In this embodiment, it is preferred that the wind impeller 64 can store the electrical energy required for the operation of the ventilation device 4 according to the principle of windmill power generation after rotation. Since windmill power generation is a common existing technology, it will not be described here, and only the wind impeller 64 is shown in the accompanying drawings.

[0058] The implementation principle of the ventilation structure of a steel structure factory building in the embodiment of the present application is as follows:

[0059] When the natural wind blows onto the second pneumatic plate 63, the natural wind pushes the second pneumatic plate 63 to drive the draft duct 5 to rotate, and can also drive the pneumatic impeller 64 to rotate. When the pneumatic impeller 64 rotates and the second pneumatic plate 63 moves at the same time, the pneumatic impeller 64 can slow down the movement speed of the second pneumatic plate 63, so that after the second pneumatic plate 63 moves to the point where the ventilation direction of the draft duct 5 is parallel to the direction of the natural wind, the influence of a slight change in wind direction of the natural wind on the ventilation direction of the draft duct 5 is reduced, thereby improving the position stability of the draft duct 5 and reducing the probability of the draft duct 5 being repeatedly rotated by the occasional natural wind in different directions.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
