Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling tower appliances, in particular to a flap structure that prevents damage from being smashed. Background Art
[0002] In the application of cooling tower heat exchange equipment, due to the harsh working environment of cooling towers, accompanied by hot and humid, corrosive air, and cooling towers are generally arranged outdoors, flaps are set in cooling towers to control the ventilation volume by adjusting the angle of the flaps. In traditional flap actuators, electric push rods are often used to push the flaps to open and change their angles through the change of the electric push rod stroke. This electric push rod opening method is more used in industries with relatively good environments such as civil construction, furniture, and medical industries. Wind, dust, rain and snow affect the working conditions of electric push rods and the stability of actuators.
[0003] A patent CN214662066U is disclosed in the prior art. The solution includes a cooling tower body, and a plurality of parallel flaps are hinged inside the cooling tower body. One end of the hinge shaft of the flap extends to the outside through the cooling tower body. An actuator is fixedly connected to the outer wall of the cooling tower body. The output shaft of the actuator is fixedly connected to a swinging driving rod. A linkage rod is fixedly connected to the outer end of the hinge shaft. A connecting rod is hinged between the swinging ends of adjacent linkage rods. The swinging end of the driving rod is hinged to the connecting rod. This solves the problem that the cooling tower working environment in traditional technology is harsh, which makes the flap driving mechanism prone to corrosion, thereby affecting the service life of the driving mechanism; and the problem that the flap is unstable during the flipping process due to the limitation of the driving structure, affecting the working efficiency of the flap.
[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:
[0005] At present, cooling towers with mist elimination structures are gradually being upgraded. However, due to the structure, the flaps of the control channels are easily damaged by ice in the upper air ducts in winter, causing breakage.
[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0007] In view of the defects in the prior art, the utility model provides an anti-damage flap structure to solve the problem that the cooling tower with a mist elimination structure in the traditional technology is gradually lifted, but due to the structure, the flap of the control channel is easily damaged by ice in the upper air duct in winter, causing damage.
[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0009] The anti-smashing flap structure includes a rotating shaft, and the opposite side walls of the rotating shaft are provided with flaps that rotate with it, and each flap is independently swung downward by an avoidance structure to avoid falling objects. The avoidance structure is also provided with a reset structure for resetting the flap to a normal state.
[0010] As an optimized solution, the avoidance structure includes a hinge connected to the hinged end of the flap, and the hinge is connected to the rotating shaft through a connecting member.
[0011] As an optimized solution, the connecting member includes an inner connecting plate fixed on the rotating shaft, and two ends of the hinge are respectively fixed to the inner connecting plate and the lower surface of the flap.
[0012] As an optimized solution, an arc-shaped plate is fixedly connected to the rotating shaft, and the inner connecting plate is fixedly connected to the opposite side walls of the arc-shaped plate.
[0013] As an optimized solution, the arc-shaped plate is fixed to the rotating shaft via a bolt assembly.
[0014] As an optimized solution, the reset structure includes a torsion spring sleeved on the hinge hinge shaft, and two ends of the torsion spring are respectively against two ends of the hinge.
[0015] As an optimized solution, a sealing strip is fixedly connected to the swing end of the flap, and a fixed outer frame is provided on one side of the flap, and the sealing strip rubs against the inner wall of the outer frame.
[0016] As an optimized solution, reinforcing plates are respectively fixed to the upper and lower surfaces of the flap.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] During the operation of the equipment, when the ice cooled on the upper part falls off, the flap of the original structure can only bear the impact of the ice. When the ice is too heavy, it is very easy to cause damage to the flap. In this structure, the flap can be independently hinged on the rotating shaft through hinges. When heavy objects fall off, the flap rotates downward with the hinge as the center under the action of the gravity of the ice or foreign objects to achieve the effect of buffering the impact. When the ice or foreign objects fall, the torsion spring in the hinge is used to bounce the flap upward to a horizontal state without changing the original working state.

[0023] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0024] like Figure 1 and Figure 2 As shown, the anti-smashing flap structure includes a rotating shaft 1, and a flap 2 that rotates with the rotating shaft 1 is provided on the opposite side wall, and each flap 2 swings downward independently through an avoidance structure to avoid falling objects. The avoidance structure is also provided with a reset structure for restoring the flap 2 to a normal state.
[0025] The avoidance structure includes a hinge 3 connected to the hinged end of the flap 2, and the hinge 3 is connected to the rotating shaft 1 through a connecting member.
[0026] The connecting member comprises an inner connecting plate 4 fixed on the rotating shaft 1 , and two ends of the hinge 3 are fixedly connected to the inner connecting plate 4 and the lower surface of the flap 2 respectively.
[0027] An arc-shaped plate 5 is fixedly connected to the rotating shaft 1 , and the inner connecting plate 4 is fixedly connected to the opposite side walls of the arc-shaped plate 5 .
[0028] The arc plate 5 is fixed to the rotating shaft 1 through a bolt assembly 9 .
[0029] The reset structure comprises a torsion spring 10 sleeved on the hinge shaft of the hinge 3 , and two ends of the torsion spring 10 respectively abut against two ends of the hinge 3 .
[0030] A sealing strip 6 is fixedly connected to the swing end of the flap 2 , and a fixed outer frame 7 is provided on one side of the flap 2 . The sealing strip 6 and the inner wall of the outer frame 7 are rubbed against each other.
[0031] The upper and lower surfaces of the flap 2 are respectively fixed with reinforcing plates 8, and the upper surface of the inner connecting plate 4 is also fixed with a reinforcing plate 8 connected to the arc plate 5. When the flap 2 is in a horizontal state, the end of the reinforcing plate 8 on the inner connecting plate 4 is against the end of the reinforcing plate 8 on the upper surface of the flap 2.
[0032] The working principle of this device is:
[0033] During the operation of the equipment, when the cooled ice on the upper part falls off, the flap 2 of the original structure can only receive the impact of the ice. When the ice is too heavy, it is very easy to cause damage to the flap. In this structure, the flap 2 can be independently hinged on the rotating shaft 1 through the hinge 3. When a heavy object falls off, the flap 2 rotates downward with the hinge 3 as the center under the action of the gravity of the ice or foreign matter (the dotted line in the figure is the avoidance state), so as to achieve the effect of buffering the impact. When the ice or foreign matter falls, the torsion spring 10 in the hinge 3 is used to bounce the flap 2 upward to a horizontal state without changing the original working state.
