Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment operation and maintenance tools, specifically a fire damper reset device for an axial flow fan. Background Technology

[0002] Fire dampers for axial flow fans in existing power plants are generally installed high up in the wall. When the fire damper malfunctions, it is difficult to close, and personnel must climb to a high place to manually close it. In addition, some power plants only use the action-closing function, and each time the fire damper is activated, it needs to be manually reset. The process is cumbersome, time-consuming, and poses certain safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a fire damper reset device for an axial flow fan in order to solve at least one of the above-mentioned technical problems.

[0004] This utility model provides a reset device for an axial flow fan fire damper, comprising: a rod body and an actuator disposed at the top of the rod body; the actuator includes two hook structures, with a notch structure provided in the middle of the two hook structures; the hook structures are used to pull down the handle of the axial flow fan fire damper; the notch structure is used to lock and push up to reset the handle of the axial flow fan fire damper.

[0005] Optionally, a handle is also provided at the bottom of the rod.

[0006] Optionally, the rod, the actuator, and the handle are integrally molded structures.

[0007] Optionally, a rubber sleeve is provided on the surface of the handle, and the surface of the rubber sleeve is provided with annular texture.

[0008] Optionally, the rod body includes a metal rod body.

[0009] Optionally, the two hook structures are arranged downwards and symmetrically distributed on both sides of the top of the rod.

[0010] This utility model provides a reset device for the fire damper of an axial flow fan. When the fire damper of the axial flow fan fails to close automatically, the operator can remotely operate the opening and closing of the fire damper by holding the reset device. This alleviates the technical problem of the difficulty in closing the existing fire damper of the axial flow fan on the wall of the power plant due to its installation at a high position on the wall.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Figure 1 This is a structural schematic diagram of a fire damper reset device for an axial flow fan according to an embodiment of this utility model. Figure 1 As shown, it includes: a rod body 1 and an actuator disposed on the top of the rod body 1; the actuator includes two hook structures 2, and a notch structure 3 is disposed in the middle of the two hook structures 2.

[0016] Specifically, the hook structure 2 is used to pull down the handle of the fire damper of the axial flow fan; The notch structure 3 is used to lock and push up the handle of the axial flow fan fire damper to reset.

[0017] Preferably, the pole 1 comprises a metal pole. For example, the pole 1 is a solid metal long pole made of high-strength alloy steel, which can ensure sufficient strength and rigidity, effectively transmit operating force, and has good resistance to deformation and corrosion, adapting to the complex environment of fire protection operation and maintenance.

[0018] Specifically, such as Figure 1As shown, two hook structures 2 are symmetrically distributed downwards on both sides of the top of the rod 1. The hook structures 2 adopt a rounded transition design to avoid damage when hooking the fire damper handle.

[0019] Preferably, the edges of the notch structure 3 are beveled to facilitate precise engagement of the fire damper handle component.

[0020] Preferably, such as Figure 1 As shown, a handle 4 is also provided at the bottom of the rod 1.

[0021] Preferably, the rod 1, the actuator, and the handle 4 are integrally molded structures.

[0022] Preferably, in this embodiment of the invention, a rubber sleeve 5 is provided on the surface of the handle 4, and the surface of the rubber sleeve 5 is provided with annular texture to increase the friction of the hand grip, so that it is not easy to slip and fatigue during long-term operation.

[0023] Figure 2 This is a schematic diagram of a fire damper reset device for an axial flow fan, provided according to an embodiment of the present invention, showing how to pull down the handle of the fire damper for an axial flow fan. Figure 3 This is a schematic diagram of a fire damper reset device for an axial flow fan, provided according to an embodiment of the present invention, showing how to push up and reset the handle of the fire damper for an axial flow fan. Figure 2 and Figure 3 As shown in the figure, the method of using the axial flow fan fire damper reset device provided in this embodiment of the utility model is as follows: In actual fire damper operation and maintenance, when the fire damper needs to be opened, maintenance personnel do not need to climb to a height. On the ground, they can hold the handle 4 and align the downward-facing hook structure 2 with the fire damper handle. By using the hooking action of the hook structure 2 to apply a downward pulling force, the fire damper can be easily opened. When the fire damper needs to be reset, the maintenance personnel adjust the position of the device so that the notch structure 3 between the two hook structures 2 precisely locks the fire damper handle. By pushing the reset plate upward, the force is transmitted through the rod 1 to drive the fire damper to complete the reset process. The entire process does not require additional auxiliary equipment, and a single person can efficiently complete the opening and reset control of the fire damper, greatly improving the convenience, safety and work efficiency of fire protection facility operation and maintenance.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
