Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and in particular to a ventilation device for steel structure workshops. Background Technology

[0002] To meet ventilation requirements, steel structure workshops typically have openings made in the insulation panels of the roof to install non-powered ventilators. These ventilators utilize natural wind and the thermal convection caused by the temperature difference between indoors and outdoors to rotate a turbine, thus achieving ventilation.

[0003] The non-powered ventilator consists of a fan and a pipe base. When installing the pipe base, the mounting bracket needs to be nailed to the top of the insulation board first, then the pipe base is placed over the mounting bracket and secured with blind rivets. However, after prolonged use, the fan may fail to rotate, likely due to internal bearing damage. This necessitates disassembling the fan and pipe base to replace and repair the bearing. However, the blind rivet installation makes disassembly inconvenient, hindering bearing replacement. Utility Model Content

A base plate 4 for mounting the mounting base 5 to the roof 1 is installed at the bottom of the mounting base 5. The device also includes:

[0024] Locking component 7 is used for mounting the pipe base 3 and the mounting seat 5. Locking component 7 includes bolt screw 71 and bolt head 72. One end of bolt screw 71 is provided with a stabilizing member for securely connecting the bolt head 72.

[0025] Connecting pipe 6 is disposed on the inner wall of mounting base 5 and is used to lock the stable connection of component 7.

[0026] A sealing element is provided on the inner wall of the pipe diameter base 3. The sealing element is used to maintain a seal between the pipe diameter base 3 and the mounting base 5.

[0027] Specifically, the top of the steel structure factory roof 1 is fixedly connected to the bottom of the base plate 4, the fan 2 is set on the top of the pipe base 3, the bottom of the mounting base 5 is fixedly connected to the top of the base plate 4, and the pipe base 3 is fitted on the outer wall of the mounting base 5.

[0028] Furthermore, the roof 1 of the steel structure factory building is the existing color steel plate roof of the steel structure factory building, and the fan 2 and the pipe base 3 are existing non-powered wind caps. By rotating the fan 2, the air inside the steel structure factory building is exchanged. The bottom end of the mounting base 5 is welded and fixed to the top end of the base plate 4. The base plate 4 is fixedly connected to the top end of the roof 1 of the steel structure factory building by pop rivets. Then, sealant is applied to the edge of the base plate 4 to maintain the seal between the roof 1 of the steel structure factory building and the base plate 4.

[0029] Specifically, the outer wall of the pipe base 3 has a first circular hole, the outer wall of the mounting base 5 has a second circular hole, the bolt 71 is inserted into the first and second circular holes, one end of the connecting pipe 6 is fixedly connected to the inner wall of the mounting base 5, one end of the connecting pipe 6 has a threaded groove, the threaded groove is interconnected with the second circular hole, one end of the bolt 71 is fixedly connected to one side of the bolt head 72, the bolt 71 is threadedly inserted into the threaded groove, the stabilizing component includes a pressing plate 73, one side of the pressing plate 73 has a third circular hole, the pressing plate 73 is sleeved on the outer wall of the bolt 71, a pushing part is provided between the pressing plate 73 and the bolt head 72, the pushing part includes a compression spring 74, the compression spring 74 is sleeved on the outer wall of the bolt 71, the compression spring 74 is used to push the pressing plate 73.

[0030] Furthermore, the locking assembly 7 is arranged in three groups, evenly spaced in a ring. The diameters of the first and second circular holes are the same, both being 1.02 times the diameter of the bolt 71. One end of the connecting pipe 6 is welded and fixed to the inner wall of the mounting base 5. The position of the connecting pipe 6 corresponds to the position of the second circular hole. The bolt 71 and the bolt head 72 form the existing bolt assembly. The thread on the outer wall of the bolt 71 meshes with the thread on the inner wall of the threaded groove of the connecting pipe 6. The two ends of the compression spring 74 are fixedly connected to the bolt head 72 and the opposite side of the pressing plate 73 by electric welding. The compression spring 74 is sleeved on the outer wall of the bolt 71. The pressing plate 73 is a metal disc. The diameter of the third circular hole of the pressing plate 73 is 1.02 times the outer diameter of the bolt 71. When the pipe diameter base 3 and the mounting base 5 are installed, the pipe diameter base 3 is first sleeved on the outside of the mounting base 5, and then the bolt 71 is... After passing through the first and second round holes in sequence, the bolt is inserted into the threaded groove. Then, by rotating the bolt head 72, the bolt screw 71 is driven to thread into the threaded groove. At this time, the outer wall of the pipe base 3 will press the pressing plate 73, and the pressing plate 73 will gradually press the compression spring 74.

[0032] Furthermore, the sealing ring 8 is a rubber ring, and two are set in the vertical direction along the pipe diameter base 3. The sealing ring 8 is fixedly connected to the inner wall of the pipe diameter base 3 by adhesive bonding. The number of slots corresponds to the number of sealing rings 8. When the pipe diameter base 3 is fitted on the outer wall of the mounting seat 5, the sealing ring 8 will extend into the slot and be squeezed and deformed by the slot, thereby filling the gap between the pipe diameter base 3 and the mounting seat 5 and achieving a sealing effect.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
