Description

Technical Field

[0001] The utility model relates to the technical field of air cooling island cleaning systems, in particular to an electromagnet mechanism for preventing an air cooling island spray ladder from returning to its original position due to inertia. Background Art

[0002] During the cleaning process of the air cooling island, the precise positioning and stable control of the spray ladder are crucial. The spray ladder usually slides along a specific track to adjust the position of the spray head to ensure the uniformity and efficiency of the cooling effect.

[0003] However, in the prior art, when the spray ladder reaches the hard limit of the track, it often continues to move for a distance due to inertia, which may cause equipment damage, uneven spraying, or even cause a safety accident.

[0004] Therefore, an electromagnet mechanism is proposed to prevent the inertial return of the air cooling island spray ladder. Utility Model Content

[0005] The purpose of the utility model is to provide an electromagnet mechanism for preventing the inertial return of an air-cooling island spray ladder, aiming to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above object, the present invention provides the following solution: The present invention provides an electromagnet mechanism for preventing the inertial return of an air-cooled island spray ladder, comprising an electromagnet, wherein at least two electromagnets are provided, and the two electromagnets are respectively mounted on the spray ladder through elastic connection components;

[0007] The spray ladder is slidably connected to a track, on which a hard limit, a limit sensor, a drive system and a control system are installed. The electromagnet, the limit sensor and the drive system are electrically connected to the control system. The electromagnet is arranged toward the track, and the electromagnet is magnetically connected to the track.

[0008] According to an electromagnet mechanism for preventing the inertial return of an air-cooled island spray ladder provided by the utility model, the elastic connection assembly includes a spring and a connecting part, one end of the spring is fixedly connected to the electromagnet, and the other end is fixedly connected to the connecting part, and the connecting part is detachably connected to the spray ladder.

[0009] According to the electromagnet mechanism for preventing the inertial return of the air-cooling island spray ladder provided by the utility model, the two connecting parts are respectively installed on both sides of the spray ladder.

[0010] According to the electromagnet mechanism for preventing the inertial return of the air-cooling island spray ladder provided by the utility model, a hook is installed at one end of the spring away from the connecting part, and the electromagnet is fixedly installed on the spring through the hook.

[0011] According to the electromagnet mechanism for preventing the inertial return of the air-cooling island spray ladder provided by the utility model, the limit sensor includes but is not limited to a mechanical sensor and a photoelectric sensor.

[0012] According to the utility model, an electromagnet mechanism for preventing the inertial return of an air-cooling island spray ladder is provided, wherein the shape of the electromagnet is any one or more of a circular ring, a cylindrical shape, a bar shape, and a U shape.

[0013] The utility model discloses the following technical effects:

[0014] The utility model can detect the approaching action of the spray ladder when the spray ladder approaches the hard limit and generate a trigger signal, which is then transmitted to the control system. The control system combines the signal information to control the electromagnet to be energized, thereby realizing the magnetic connection between the electromagnet and the track. The electromagnet quickly generates magnetic force when it is energized and is fixedly adsorbed on the track, thereby acting on the spray ladder to overcome its inertia and prevent the spray ladder from continuing to move along the track, thereby firmly locking the spray ladder in a predetermined position, effectively preventing the safety hazards caused by inertial return, not only improving the overall safety of the equipment, but also ensuring the stable operation of the spray ladder under harsh working conditions and good reliability. When the spray ladder needs to be moved, the control system will first cut off the power supply of the electromagnet to make it lose its magnetic force, and then start the drive system to safely move the spray ladder to the required position.

[0015] The control system of the utility model adjusts the presence or magnitude of the current flowing into the electromagnet, allowing the electromagnet to generate or cancel magnetic force, thereby achieving traction or braking of the spray ladder. The electromagnet serves as a power source, and the generation and disappearance of magnetic force are controlled by the on and off of the current. The elastic connection component plays a reset and buffering role, ensuring that the equipment can smoothly return to its initial position when the power is cut off or the magnetic force is lost. The elastic connection component is also responsible for connecting the electromagnet and the spray ladder to form an integrated system.

[0016] The electromagnet mechanism in the utility model is installed on the spray ladder through an elastic connection component. The installation position and magnetic force can be adjusted according to actual needs to adapt to the requirements of different models of spray ladders and tracks. The structure is simple, the complexity of the control system is simplified, the maintenance cost is reduced, and the versatility and flexibility of the mechanism are enhanced, so that it can be widely used in various air-cooling island equipment.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1 The utility model provides an electromagnet mechanism for preventing the inertia return of the air-cooling island spray ladder, comprising an electromagnet 1, at least two electromagnets 1 are provided, and the two electromagnets 1 are respectively installed on the spray ladder 5 through elastic connection components;

[0023] The spray ladder 5 is slidably connected to the track 6, which is equipped with a hard limit, a limit sensor, a drive system, and a control system. The electromagnet 1, the limit sensor, and the drive system are electrically connected to the control system. The electromagnet 1 is set toward the track 6 and is magnetically connected to the track 6. The control system includes a battery and a control element. The battery, the electromagnet 1, the limit sensor, and the drive system are electrically connected to the control element, and the control element adopts a PLC.

[0024] When the spray ladder 5 is moved, the control system will first cut off the power supply of the electromagnet 1 to make it lose its magnetic force, and then start the drive system to move the spray ladder 5 to the desired position.

[0025] The control system of the utility model adjusts the presence or magnitude of the current flowing into the electromagnet 1, so that the electromagnet 1 can generate or cancel the magnetic force, thereby achieving traction or braking of the spray ladder 5. The electromagnet 1 serves as a power source and controls the generation and disappearance of the magnetic force by turning the current on and off. The elastic connection component plays a reset and buffering role, ensuring that the equipment can smoothly return to its initial position when the power is cut off or the magnetic force is lost. The elastic connection component is also responsible for connecting the electromagnet and the spray ladder to form an integrated system.

[0026] The electromagnet mechanism in the utility model is installed on the spray ladder 5 through an elastic connection component. The installation position and the size of the magnetic force can be adjusted according to actual needs to adapt to different models of spray ladders 5 and track requirements. The structure is simple, the complexity of the control system is simplified, the maintenance cost is reduced, and the versatility and flexibility of the mechanism are enhanced, so that it can be widely used in various air-cooling island equipment; for example, it can be applied to the upper and lower synchronous drive device for the air-cooling island cleaning system of a power plant with publication number CN212567102U to achieve the fixation of the spray ladder.

[0027] Further optimized, the elastic connection assembly includes a spring 2 and a connection part 3, one end of the spring 2 is fixedly connected to the electromagnet 1, and the other end is fixedly connected to the connection part 3, and the connection part 3 is detachably connected to the spray ladder 5;

[0028] Spring 2 serves as the main elastic element, with one end fixed to the electromagnet 1 and the other end connected to the spray ladder 5 through the connecting part 3. When the electromagnet 1 is energized to generate magnetic force and adsorbed on the track, the spring 2 is in a stretched state. When the electromagnet 1 is powered off and loses its magnetic force, the elastic force of the spring 2 helps the electromagnet 1 to return to its initial position smoothly, providing stable support for the electromagnet 1.

[0029] To further optimize the solution, the two connecting parts 3 are respectively installed on both sides of the spray ladder 5.

[0030] According to a further optimized solution, a hook 4 is installed at one end of the spring 2 away from the connecting portion 3, and the electromagnet 1 is fixedly mounted on the spring 2 via the hook 4. The fixed connection between the electromagnet 1 and the spring 2 can be conveniently achieved via the hook 4.
