Description

Technical Field

[0001] The present invention belongs to the technical field of building ventilation and relates to a ventilation device for building construction. Background Art

[0002] Ventilation is a building environment control technology that controls the spread and harm of air pollutants by means of ventilation dilution or ventilation exclusion, etc., to ensure the quality of the indoor and outdoor air environment of building construction. A ventilation device is a device used to achieve indoor and outdoor ventilation of a building.

[0003] The current ventilation devices mainly include an exhaust fan for being arranged in a building. Fixing holes are penetrated through the wall of the building, and the exhaust fan is fixed in the fixing holes by screws. When ventilation of the building is required, an operator starts the exhaust fan. At this time, the turbid air in the building is sucked outdoors by the exhaust fan, and fresh air outdoors blows into the building through the windows of the building.

[0004] For example, a ventilation device for building construction disclosed in the authorized publication number CN112880088B includes an air extraction fan for sucking turbid air in the building. A hanging plate is arranged inside the top of the building. An air extraction port is penetrated through the bottom of the hanging plate along the length direction of the hanging plate. The air extraction fan is arranged on the top of the hanging plate. The input end of the air extraction fan is communicated with the air extraction port. The output end of the air extraction fan is communicated with an exhaust hose. The other end of the exhaust hose passes through the building and extends outside the side wall of the building. A moving seat is slidably arranged above the air extraction port on the hanging plate. The air extraction fan is connected to the moving seat through a fixing component. A driving component for driving the moving seat to slide along the length direction of the hanging plate is arranged on the hanging plate. This application has the effect of improving the ventilation efficiency of the ventilation device.

[0005] However, in the above solution, the power of the air extraction fan is fixed, and the effect of improving the ventilation efficiency by only sucking air at different positions through the movement of the extraction fan is relatively limited. Therefore, a ventilation device for building construction is proposed, which can efficiently discharge the air in the building. Summary of the Invention

[0006] The object of the present invention is to provide a ventilation device for building construction in view of the above problems existing in the prior art.

[0007] The object of the present invention can be achieved by the following technical solutions: A ventilation device for building construction, including a building body, ventilation holes, and ventilation pipes arranged outside the ventilation holes. One end of the ventilation pipe is communicated with the interior, and the other end is communicated with the outside. The ventilation pipe includes an air delivery pipe connected to the building body, a first branch pipe, a second branch pipe, an output pipe, and a connecting rod. The air delivery pipe, the first branch pipe, the second branch pipe, and the output pipe are successively welded to the bottom of the connecting rod. A first interval cavity is formed between the air delivery pipe and the first branch pipe, a second interval cavity is formed between the first branch pipe and the second branch pipe, and a third interval cavity is formed between the second branch pipe and the output pipe. An installation rod is horizontally arranged on the outside of the building body, and a first connecting sleeve, a second connecting sleeve, and a third connecting sleeve are successively arranged on the installation rod. A first exhaust fan and a first connecting pipe are symmetrically arranged at both ends of the first connecting sleeve, a second exhaust fan and a second connecting pipe are symmetrically arranged at both ends of the second connecting sleeve, and a third exhaust fan and a third connecting pipe are symmetrically arranged at both ends of the third connecting sleeve. A driving component is also arranged on the outside of the building body for driving the first exhaust fan, the second exhaust fan, and the third exhaust fan to switch with the first connecting pipe, the second connecting pipe, and the third connecting pipe respectively.

[0008] In the above-mentioned ventilation device for building construction, a protective block is also arranged on one side of the building body. Three protective grooves are successively arranged on the protective block, and the protective grooves horizontally penetrate through the protective block. The first connecting sleeve, the second connecting sleeve, and the third connecting sleeve are respectively located in each protective groove. By arranging the first connecting sleeve, the second connecting sleeve, and the third connecting sleeve in the protective grooves, it can play a protective role for the first connecting sleeve, the second connecting sleeve, and the third connecting sleeve when not in use; at the same time, when the first exhaust fan, the second exhaust fan, and the third exhaust fan rotate into the protective grooves, it also plays a protective role for the first exhaust fan, the second exhaust fan, and the third exhaust fan, thereby improving the service life of the first exhaust fan, the second exhaust fan, and the third exhaust fan.

[0009] In the above-mentioned ventilation device for building construction, there are three driving components, which are respectively used to independently control the rotation of the first connecting sleeve, the second connecting sleeve, and the third connecting sleeve.

[0010] In the above-mentioned ventilation device for building construction, the driving component includes a driving motor on the protective block. The output end of the driving motor is provided with a driving wheel, and the first connecting sleeve is provided with a driven wheel. The driving wheel and the driven wheel are meshed with each other.

[0011] In the above-mentioned ventilation device for building construction, an air suction pipe is arranged inside the ventilation hole. The air suction pipe is arranged in an L shape and can rotate in the ventilation hole. A rotating component for driving the air suction pipe to rotate is arranged inside the building body.

[0012] In the above-mentioned ventilation device for building construction, the rotating assembly includes a rotating motor arranged inside the building. A rotating gear is arranged on the output shaft of the rotating motor. Teeth meshing with the rotating gear are arranged on the air suction pipe, and the teeth are distributed in a semicircular shape.

[0013] In the above-mentioned ventilation device for building construction, a controller is further arranged inside the building, and control buttons for respectively controlling three driving assemblies are arranged on the controller.

[0014] In the above-mentioned ventilation device for building construction, sealing rings are arranged at both ends of the first connecting pipe, the second connecting pipe, and the third connecting pipe. The arrangement of the sealing rings can improve the airtightness between them when the first connecting pipe, the second connecting pipe, and the third connecting pipe rotate into the first interval cavity, the second interval cavity, and the third interval cavity.

[0015] In the above-mentioned ventilation device for building construction, a limiting groove is formed on the mounting rod. The first connecting sleeve, the second connecting sleeve, and the third connecting sleeve are respectively located in the corresponding limiting grooves, which can limit the first connecting sleeve, the second connecting sleeve, and the third connecting sleeve during rotation and prevent them from shifting left and right.

[0016] Compared with the prior art, by setting three driving assemblies to respectively control the rotation of the corresponding first rotating sleeve, second rotating sleeve, and third rotating sleeve, the invention can rotate the exhaust fan into the corresponding interval cavity, thereby controlling the magnitude of the wind force in the ventilation pipe, enabling the operator to adjust it according to the turbidity of the indoor air, and thus improving the ventilation efficiency.

[0023] As Figures 1 to 3 shown, a ventilation device for building construction includes a building body 1, a ventilation hole 2 and a ventilation pipe 3 arranged outside the ventilation hole 2. One end of the ventilation pipe 3 is communicated with the interior, and the other end is communicated with the outside.

[0024] A suction pipe 20 is arranged inside the ventilation hole 2. The suction pipe 20 is arranged in an L shape and can rotate in the ventilation hole 2. A rotating assembly 21 for driving the suction pipe 20 to rotate is arranged inside the building body 1.

[0025] The rotating assembly 21 includes a rotating motor 211 arranged inside the building body 1. A rotating gear 212 is arranged on the output shaft of the rotating motor 211. Teeth 213 meshing with the rotating gear 212 are arranged on the suction pipe 20. The teeth 213 are distributed in a semicircle. The semicircular distribution of the teeth 213 enables the adjustment angle of the suction pipe 20 to be 180 degrees.

[0026] Start the rotating motor 211. The output shaft of the rotating motor 211 rotates to drive the rotating gear 212 to rotate. The rotating gear 212 meshes with the teeth 213 on the suction pipe 20 to drive the suction pipe 20 to rotate, so that the orientation of the suction pipe 20 can be adjusted, enabling it to exhaust air in different directions, thereby improving the exhaust efficiency.

[0027] The ventilation pipe 3 described above includes an air delivery pipe 31 connected to the building body 1, a first branch pipe 32, a second branch pipe 33, an output pipe 34, and a connecting rod 35. The air delivery pipe 31, the first branch pipe 32, the second branch pipe 33, and the output pipe 34 are successively welded to the bottom of the connecting rod 35. A first spacer cavity 4 is formed between the air delivery pipe 31 and the first branch pipe 32, a second spacer cavity 5 is formed between the first branch pipe 32 and the second branch pipe 33, and a third spacer cavity 6 is formed between the second branch pipe 33 and the output pipe 34. An installation rod 7 is horizontally arranged on the outer side of the building body 1. A first connecting sleeve 8, a second connecting sleeve 9, and a third connecting sleeve 10 are successively arranged on the installation rod 7. A first exhaust fan 11 and a first connecting pipe 12 are symmetrically arranged at both ends of the first connecting sleeve 8 respectively. A second exhaust fan 13 and a second connecting pipe 14 are symmetrically arranged at both ends of the second connecting sleeve 9 respectively. A third exhaust fan 15 and a third connecting pipe 16 are symmetrically arranged at both ends of the third connecting sleeve 10 respectively.

[0028] Both the first exhaust fan 11 and the first connecting pipe 12 are welded to the first connecting sleeve 8 through a short rod 26.

[0029] A protective block 17 is further arranged on one side of the building body 1. Three protective grooves 18 are successively formed on the protective block 17. The protective grooves horizontally penetrate through the protective block 17. The first connecting sleeve 8, the second connecting sleeve 9, and the third connecting sleeve 10 are respectively located in the respective protective grooves 18. By arranging the first connecting sleeve 8, the second connecting sleeve 9, and the third connecting sleeve 10 in the protective grooves 18, it can play a protective role for the first connecting sleeve 8, the second connecting sleeve 9, and the third connecting sleeve 10 when not in use; at the same time, when the first exhaust fan 11, the second exhaust fan 13, and the third exhaust fan 15 rotate into the protective grooves 18, it also plays a protective role for the first exhaust fan 11, the second exhaust fan 13, and the third exhaust fan 15, thereby improving the service life of the first exhaust fan 11, the second exhaust fan 13, and the third exhaust fan 15.

[0030] A driving assembly 19 for driving the first exhaust fan 11, the second exhaust fan 13, and the third exhaust fan 15 to switch with the first connecting pipe 12 and the second connecting pipe 14 is further arranged on the outer side of the building body 1. The driving assembly 19 includes a driving motor 191 on the protective block 17. A driving wheel 192 is arranged at the output end of the driving motor 191. A driven wheel 193 is arranged on the first connecting sleeve 8. The driving wheel 192 meshes with the driven wheel 193.

[0031] Start the drive motor 191. The rotation of the output end of the drive motor 191 drives the rotation of the driving wheel 192. The driving wheel 192 meshes with the driven wheel 193 to drive the rotation of the driven wheel 193. The rotation of the driven wheel 193 drives the rotation of the first connecting sleeve 8. When the first connecting sleeve 8 rotates 180 degrees, the switching between the first exhaust fan 11 and the first connecting sleeve 8 is realized. Similarly, the second connecting sleeve 9 and the second exhaust fan 13, and the third connecting sleeve 10 and the third exhaust fan 15 can all complete the switching through separate drive assemblies 19. The operator can use one, two or three exhaust fans simultaneously according to the turbidity of the air in the room, thereby improving the ventilation effect.

[0032] In this embodiment, three drive assemblies 19 are provided and are respectively used to independently control the rotation of the first connecting sleeve 8, the second connecting sleeve 9, and the third connecting sleeve 10.

[0033] A controller 22 is further provided inside the building body 1. Control buttons 23 for respectively controlling the three drive assemblies 19 are provided on the controller 22.

[0034] Sealing rings 24 are provided at both ends of the first connecting pipe 12, the second connecting pipe 14, and the third connecting pipe 16. The provision of the sealing rings 24 can improve the airtightness between them when the first connecting pipe 12, the second connecting pipe 14, and the third connecting pipe 16 rotate into the first spacer cavity 4, the second spacer cavity 5, and the third spacer cavity 6.

[0035] Limit grooves 25 are formed on the mounting rod 7.

[0036] By providing three drive assemblies 19 to respectively control the rotation of the corresponding first rotating sleeve, second rotating sleeve, and third rotating sleeve, the present invention can rotate the exhaust fan into the corresponding spacer cavity, thereby controlling the magnitude of the wind force in the ventilation pipe 3, enabling the operator to adjust it according to the turbidity of the air in the room, and thus improving the ventilation efficiency.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
