DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: an air cooler for a steam turbine in a thermal power plant, which is easy to disassemble a filter screen, comprising a fixing cylinder 1, a blowing cylinder 2, a blowing device 3, a mounting frame 4, a supporting column 5, a movable plate 6, a convex block 7, a cooling device 8, a condenser 9, a dust filter screen 10, a fixing mechanism 11, a fixing block 12, a movable bolt 13, a limit plate 14 and an auxiliary block 15.

[0031] When using the thermal power plant steam turbine air cooler with easy-to-remove filter screen, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a blower 2 is fixedly connected to the left side of the fixed cylinder 1, and a blower device 3 is fixedly installed inside the blower 2. The blower device 3 is used to blow air, and the wind blows toward the steam turbine of the thermal power plant through the blower 2, so as to cool and dissipate heat for the steam turbine. Moreover, a cooling device 8 is fixedly installed on the upper end of the fixed cylinder 1. The cooling device 8 is connected to the condenser 9. The cooling device 8 circulates and continuously cools the coolant in the condenser 9, so as to facilitate cooling the wind blown out by the blower device 3 and blow the coolant toward the steam turbine, thereby greatly improving the actual heat dissipation efficiency. Moreover, the condenser 9 is curved in the fixed cylinder 1, thereby increasing the contact area with the wind, achieving a better heat dissipation effect, and having high practicality.

[0032] Then, according to the actual position of the heat source, the movable plate 6 is pulled, the movable plate 6 and the support column 5 are rotated, and the torsion spring at the connection between the movable plate 6 and the support column 5 is elastically deformed. At this time, the movable plate 6 is disengaged from the protrusion 7, thereby releasing the limit between the support column 5 and the mounting frame 4, and then the movable plate 6 is rotated to drive the support column 5 and the mounting frame 4 to rotate, so that the support column 5 drives the hair dryer 2 and the fixed tube 1 to flip, thereby aligning the hair dryer 2 with the position of the heat source to achieve a more accurate heat dissipation effect, and the heat dissipation effect is better. After the angle adjustment is completed, the movable plate 6 is directly released, and the torsion spring recovers its elastic deformation at this time, driving the movable plate 6 to flip upward, and the protrusion 7 is set at an equal angle on the upper end of the mounting frame 4, which is convenient for limiting the support column 5 and the mounting frame 4;

[0033] In addition, during the blowing process, the dust filter 10 is engaged with the right end of the fixed cylinder 1 to prevent the dust in the air from being blown onto the turbine, thereby achieving a good dust prevention effect. Figure 1 , Figure 5 and Figure 6 As shown, the fixing mechanism 11 is symmetrically arranged at the front and rear ends of the fixing cylinder 1, and the fixing mechanism 11 includes a fixing block 12 fixedly connected to the front and rear ends of the fixing cylinder 1, a movable bolt 13 for adjustment, a limit plate 14 rotatably connected to the right end of the movable bolt 13, and an auxiliary block 15 for positioning. By rotating the movable bolt 13 threadedly connected to the middle of the fixing block 12, the movable bolt 13 and the limit plate 14 rotate, so that the limit plate 14 moves to the right. At this time, the limit plate 14 is disengaged from the auxiliary block 15, and then the limit plate 14 is flipped, and the limit plate 14 is moved away from the right end of the dust filter 10 to prevent interference between the limit plate 14 and the dust filter 10. Then, the dust filter 10 is pulled to the right to be removed from the right end of the fixing cylinder 1, so as to facilitate the disassembly and cleaning of the dust filter 10 to prevent excessive dust on the dust filter 10 and cause clogging.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
