Description

Technical Field

[0001] The utility model relates to a fixed ring seat of a turbine fan, belonging to the technical field of turbine fans. Background Art

[0002] Turbine fans, also known as unpowered fans, are mostly rationally installed on carriers such as factory roofs. Based on the principle of "thermal expansion and contraction", the heat generated by the operation of machine tools in the factory creates a temperature difference between the inside and outside of the house, and the turbine fans start to operate, thereby transforming the parallel air flow into a vertical flow from indoors to outdoors from bottom to top, thereby quickly exhausting the indoor heat and dirty gas and improving the indoor environment;

[0003] The fixing ring seat is one of the main accessories of the turbine fan. When installing, a reserved hole and multiple holes are usually processed on the roof or other carriers. Then the fixing ring seat is inserted into the reserved hole, and the mounting hole on the fixing ring seat is aligned with the hole. Then, the fixing ring seat and the carrier are fastened and installed by bolts and nuts.

[0004] However, in order to ensure that the bolt can pass through the hole normally, the size of the hole will be made larger than the size of the bolt rod. After the fixing ring seat is tightened and installed, a gap will easily occur between the bolt rod and the hole, resulting in a high probability of rainwater leakage and poor safety.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a fixed ring seat of a turbine fan, comprising a ring seat body 1, a mounting ring 6 located on the upper side of an upper ring plate 3 is sleeved on the outer end of the ring seat body 1, and a mounting carrier is provided for components such as turbine blades through the mounting ring 6;

[0026] An annular groove 14 is formed on the outer end surface of the ring seat body 1, and the annular groove 14 provides an installation space for the slider 61. A plurality of sliders 61 slidably connected in the annular groove 14 are equidistantly arranged on the inner wall of the mounting ring 6. The plurality of sliders 61 cooperate with the annular groove 14 to make the mounting ring 6 and the ring seat body 1 slidably connected.

[0027] The fixed part of the rolling member whose movable part is rollingly connected to the inner wall of the annular chute 14 is installed on the middle part of the inner end of the slider 61, and the rolling member is used to assist the slider 61 to rotate in the annular chute 14. The rolling member can be a bull's eye 62, and the outer end surface of the ring seat body 1 is inwardly recessed to form a plurality of grooves 11 arranged vertically and extending to the upper end of the ring seat body 1 and connected to the upper end of the annular chute 14, and the grooves 11 are used to assist the slider 61 to enter and exit the annular chute 14;

[0028] The limiting plate 13 is fitted on the vertical wall inside the groove 11, and the anti-sliding block 61 is separated from the groove 11 through the limiting plate 13, and one page of the elastic hinge whose other page is set on the vertical wall inside the groove 11 is installed on the lower end of the limiting plate 13, and the limiting plate 13 and the inner wall of the groove 11 are movably installed through the elastic hinge, and then the baffle plate 12 fitted on the upper end of the limiting plate 13 is installed on another vertical wall inside the groove 11, and the limiting plate 13 is limited by the baffle plate 12.

[0029] During assembly, the mounting ring 6 is first placed on the ring seat body 1, and the plurality of sliders 61 are aligned with the upper ends of the plurality of grooves 11 respectively, and then the mounting ring 6 is moved downward, so that the sliders 61 enter the grooves 11, and the sliders 61 contact the upper ends of the limit plates 13, and then the mounting ring 6 is further moved downward, so that the sliders 61 continue to move downward along the grooves 11, thereby applying downward pressure to the limit plates 13, and causing the limit plates 13 to rotate around the axis of the elastic hinge;

[0030] Then, the slider 61 is passed through the groove 11 and enters the annular slide groove 14, so that the installation ring 6 and the ring seat body 1 can be easily disassembled and assembled, which is convenient for assembly and maintenance. At the same time, after the slider 61 enters the annular slide groove 14, the slider 61 will separate from the limit plate 13. At this time, under the elastic action of the elastic hinge, the limit plate 13 will rotate and contact the baffle 12. The structure formed by the limit plate 13 and the baffle 12 will block the groove 11, effectively preventing the slider 61 from detaching from the groove 11, thereby increasing the installation stability.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the upper ring plate 3 is arranged on the outer end of the ring seat body 1, and the installation position of the mounting bolt 5 is limited by the upper ring plate 3, and the lower ring plate 2 located at the lower side of the upper ring plate 3 is installed on the outer end of the ring seat body 1, and the installation position of the ring seat body 1 is limited by the lower ring plate 2, and then the sealing member located at the outer end of the ring seat body 1 is arranged on the lower end of the lower ring plate 2, and the lower ring plate 2 is sealed and connected with the installation carrier such as the roof through the sealing member, and the sealing member can be an annular rubber pad 4;

[0032] A plurality of first holes penetrating the upper ring plate 3 are formed on the upper end surface of the upper ring plate 3 and recessed downwards, and the mounting bolts 5 are passed through the upper ring plate 3 through the first holes; a plurality of second holes penetrating the lower ring plate 2 and located directly below the first holes are formed on the upper end surface of the lower ring plate 2 and recessed, and the mounting bolts 5 are passed through the lower ring plate 2 through the second holes; a plurality of third holes penetrating the seal and communicating with the lower ends of the second holes are formed on the lower end surface of the seal and recessed upwards, and the mounting bolts 5 are passed through the seal through the third holes;

[0033] A plurality of sector-shaped rubber sheets 41 which are integrated with the seal are equidistantly arranged on the inner wall of the third hole. The sector-shaped rubber sheets 41 can be used to block the gaps generated on the mounting carrier, and the caps of the mounting bolts 5 whose rods pass through the first hole, the second hole and the third hole are equidistantly fitted on the upper end of the upper ring plate 3. The mounting bolts 5 are used to provide a mounting carrier for the nut 51, and the nut 51 located on the lower side of the seal and on the outer side of the ring seat body 1 is threadedly connected to the outer end of the rod of the mounting bolt 5. The mounting bolts 5 and the nut 51 are used in combination to ensure that the ring seat body 1 and the mounting carrier are securely mounted.

[0034] During installation, first insert the lower part of the ring seat body 1 into the reserved hole on the installation carrier such as the roof, and make the annular rubber pad 4 fit the outer end of the installation carrier, then the rod of the installation bolt 5 passes through the first hole, the second hole, the third hole and the hole on the installation carrier and contacts the nut 51, and then the installation bolt 5 is rotated, so that the installation bolt 5 and the nut 51 are threadedly connected, so that the ring seat body 1 and the installation carrier are fastened and installed, and at this time, the lower ring plate 2 will squeeze the annular rubber pad 4 on the installation carrier to achieve a sealed connection between the ring seat body 1 and the installation carrier;

[0035] And when the rod of the mounting bolt 5 passes through the third hole, the multiple fan-shaped rubber sheets 41 will expand outward, and then the expanded fan-shaped rubber sheets 41 will enter the holes on the mounting carrier. At this time, the fan-shaped rubber sheets 41 will block the gap between the rod of the mounting bolt 5 and the holes on the mounting carrier, effectively reducing the probability of rainwater leakage, with good safety. If the mounting bolt 5 and the nut 51 cannot be disassembled, the rod of the mounting bolt 5 located between the upper ring plate 3 and the lower ring plate 2 can be cut, effectively ensuring that the ring seat body 1 can be normally disassembled for easy maintenance.
