Description

Technical Field

[0001] The invention relates to the technical field of cooling tower fans, and in particular to a cooling tower fan with high structural strength. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It is an evaporative heat dissipation device that dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The wind duct of a traditional cooling tower fan is weak in terms of wind resistance and cannot cope with the impact of changes in wind force and direction on the wind duct's wind resistance in different seasons and environments. The cooling tower's handling capacity cannot be guaranteed under strong wind conditions, and the wind duct is prone to damage. Therefore, designing a cooling tower fan with high structural strength that can match wind force and direction and improve the wind duct's ability to resist wind changes has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a cooling tower fan with high structural strength.

[0004] The technical solution of the utility model is a cooling tower fan with high structural strength, comprising a duct, a motor and a fan, the duct being provided with a mounting frame connected to the motor, the fan being arranged at the axial center position of the duct, the motor being connected to the fan for cooperative driving, the duct being provided with a movable track along the lower edge, the movable track being connected to a plurality of movable seats, the movable seats being connected to a support member extending upward, a fixing bolt being installed on the top of the support member, and a plurality of bolt holes matching the fixing bolts being also provided on the top of the duct, the bolt holes being arranged at intervals along the circumferential direction of the duct.

[0005] After adopting the above structure, the movable seat is pushed along the movable track to move the support member on the side of the wind tube, and the fixing bolt is passed through the bolt hole to fix the top of the support member to the top of the wind tube, and the position of the support member is locked to match the position of the support member with the wind direction. The support member is respectively connected to the bottom and the top of the wind tube through the movable seat and the fixing bolt, providing support in the vertical direction and limiting the side of the wind tube to prevent the wind tube from bending to the side; it can also be fixed in one place in different numbers according to the strength of the wind, so as to further improve the support strength.

[0006] As a further improvement of the utility model, the support member is an arc-shaped plate, and the concave surface of the support member fits with the side surface of the wind tube.

[0007] With the above structure, the arc surface of the support member fits with the side of the wind tube, thereby improving the fit between the support member and the wind tube, and further preventing the wind tube from deforming toward the side where the support member is located.

[0008] As a further improvement of the utility model, a plurality of reinforcing ribs are arranged on the side of the support member, and the reinforcing ribs are interwoven to form a mesh structure.

[0009] After adopting the above structure, the strength of the support member is improved by interweaving the reinforcing ribs into a mesh structure, thereby increasing the pressure that the support member can withstand.

[0010] As a further improvement of the utility model, a first flange plate is provided on the top of the support member, the fixing bolts are mounted on the first flange plate, a second flange plate is provided on the upper edge of the wind tube, and the bolt holes are arranged on the second flange plate.

[0011] After adopting the above structure, the fixing bolts on the first flange plate are aligned with the bolt holes on the second flange plate, so that the connection and separation between the end of the support member and the wind tube are more concise and accurate.
