Description

Technical Field

[0001] The invention relates to the technical field of generator set supporting devices, and in particular to a manual-automatic integrated air intake and exhaust control system supporting an AC generator set. Background Art

[0002] Electricity is one of the most important energy sources in modern society. A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. The working principle of the generator is to use the electromagnetic induction principle that uses the wire cutting the magnetic lines to induce the electric potential, and convert the mechanical energy of the prime mover into electrical energy output. The synchronous generator consists of two parts: the stator and the rotor. The stator is the armature that generates electricity, and the rotor is the magnetic pole. The stator consists of an armature core, a uniformly discharged three-phase winding, a base, and an end cover. The rotor is usually a hidden pole type, consisting of an excitation winding, an iron core and a shaft, a guard ring, a center ring, etc. A DC current is passed through the rotor's excitation winding to generate a magnetic field close to a sinusoidal distribution (called a rotor magnetic field), and its effective excitation flux intersects with the stationary armature winding. When the rotor rotates, the rotor magnetic field rotates along with it. For each revolution, the magnetic lines of force sequentially cut through each phase winding of the stator, inducing a three-phase AC potential in the three-phase stator winding. When the generator is running with a symmetrical load, the three-phase armature current synthesizes to produce a rotating magnetic field with a synchronous speed. The interaction between the stator magnetic field and the rotor magnetic field will generate a braking torque. From the steam turbine / hydraulic turbine / gas turbine, the input mechanical torque overcomes the braking torque and works. Generator sets are often used in power plants to achieve power generation operations. Generator sets will generate a lot of heat when in use, and at this time, the exhaust vents need to be opened to dissipate the heat.

[0003] At present, independent electric exhaust vents are installed inside the machine room composed of generator sets to realize exhaust operation. Such electric exhaust mechanism is generally equipped with an independent power supply to control it and uses multiple motors to realize the switching operation of the exhaust mechanism. However, when multiple motors are used to realize the switching, it will not only increase the cost, but also it is difficult to ensure the simultaneous rotation of multiple motors to realize the simultaneous opening of the exhaust vents after long-term use, which may easily cause the exhaust vents to not be fully opened, affecting actual use.

[0004] The electric exhaust mechanism currently used generally utilizes the rotation of a motor to realize the opening and closing of the electric exhaust port, but its opening and closing state is always maintained by the motor, that is, when the motor is powered off, it cannot maintain the current switch state. It does not have a manual locking function. In actual use, if a power outage occurs during use, the switch state cannot be maintained, causing inconvenience in use.

[0005] Existing electric air inlet and exhaust products in the generator room need to be installed with an independent electrical control system to achieve synchronization with the generator set, and generally do not have a manual opening function when the external power supply is cut off. When there is no external power supply, the air inlet and exhaust vents will not be able to open, seriously affecting the safe operation of the generator set. Summary of the invention

[0006] The present invention provides a manual-automatic integrated air intake and exhaust control system for an AC generator set, which has the advantages of reducing costs, having a manual locking function, and facilitating manual control of the opening and closing of the exhaust port, thereby solving the problems raised in the above-mentioned background technology.

[0007] The present invention provides the following technical solution: a manual-automatic integrated air intake and exhaust control system for an AC generator set, comprising a shell, wherein movable grooves are provided on the outer side surfaces of the shell near the four corners, and movable blocks are movably installed inside the movable grooves, and movable plates are fixedly installed at the top ends of the two movable blocks, and a movable seat is fixedly installed between the two movable plates, and a linear motor is fixedly installed at the top end of the movable seat, and a fixing hole is provided at the top end of the linear motor, and a push rod is fixedly installed at the bottom end of the movable block, and a baffle is provided at the bottom end of the push rod.

When it is necessary to control the opening and closing of the baffle, the linear motor can be turned on to drive the movable seat to move up and down, and then drive the movable plate and the movable block to move up and down. At this time, the movable block can be displaced relative to the movable groove to drive the up and down displacement of the four push rods at the bottom, and finally drive the up and down displacement of the baffle to realize the opening and closing of the exhaust port, avoiding the use of multiple motors to rotate and open, thereby achieving the advantage of reducing costs.

When the movable seat is driven to move by the linear motor, the connecting rod located inside the limit groove is immediately displaced inside the limit groove. When the movable seat reaches a predetermined height, the threaded sleeves on the threaded rods at both ends can be rotated to drive the threaded sleeves to move relative to the threaded rods, so that they are locked with the housing to avoid movement of the connecting rod, and then avoid displacement of the baffle, thereby achieving the advantage of manual locking function.

At this time, the movable seat can be driven up and down by the drive of the traction rope to realize the opening and closing of the baffle, thereby realizing the advantage of convenient manual control of the opening and closing of the exhaust port.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-5 A manual-automatic integrated air intake and exhaust control system for an AC generator set includes a shell 1, and movable grooves 2 are provided on the outer side of the shell 1 near the four corners, so that movable blocks 9 are movably installed inside the movable grooves 2, and movable plates 11 are fixedly installed on the tops of the two movable blocks 9, and a movable seat 12 is fixedly installed between the two movable plates 11, and a linear motor 4 is fixedly installed on the top of the movable seat 12, and a fixing hole 5 is provided on the top of the linear motor 4, and a push rod 8 is fixedly installed on the bottom end of the movable block 9, and a baffle 6 is provided on the bottom end of the push rod 8.

[0025] Among them, the left and right sides of the baffle 6 are fixedly installed with a rotating shaft 7, and the other end of the push rod 8 is rotatably connected to the rotating shaft 7. The baffle 6 can rotate relative to one push rod 8, but when the two push rods 8 fix the baffle 6, its rotation is restricted so that it can only move with the push rod 8 and has higher stability.

[0026] Among them, reinforcing ribs 13 are fixedly installed at the upper and lower ends of the two movable plates 11, and a through groove 14 is opened at the top of the reinforcing rib 13. The reinforcing rib 13 can increase the stability between the two movable plates 11 and reduce the pressure of the movable seat 12. At the same time, the through groove can reduce the weight of the reinforcing rib 13 and reduce the pressure of the device.

[0027] Among them, the upper and lower ends of the movable block 9 are fixedly installed with buffer springs 10 located inside the movable groove 2, and the upper and lower ends of the buffer spring 10 are fixedly connected to the upper and lower ends of the movable groove 2. The buffer springs 10 at the upper and lower ends of the movable block 9 can provide buffering and reset when subjected to pressure.

[0028] Among them, limiting grooves 3 are provided at both ends of the shell 1, and connecting rods 15 are fixedly installed at both ends of the bottom of the linear motor 4. One end of the connecting rod 15 passes through the limiting groove 3 and is fixedly installed with a threaded rod 16. The outer side surface of the threaded rod 16 is threadedly connected with a threaded sleeve 17. When the movable seat 12 reaches a predetermined height, the threaded sleeve 17 on the threaded rods 16 at both ends can be rotated to drive the threaded sleeve 17 to move relative to the threaded rod 16, so that it is locked between the shell 1 to prevent the movement of the connecting rod 15.

[0029] Among them, a fixing frame 18 is fixedly installed on both the front and back sides of the bottom end of the shell 1, and a transmission shaft 19 is movably installed inside the fixing frame 18. A pulley 20 is fixedly sleeved in the middle of the transmission shaft 19, and a turntable 22 is fixedly installed on the other end of the transmission shaft 19. A traction rope 21 is wound around the pulley 20, and the top of the traction rope 21 is fixedly connected to the bottom end of the movable seat 12. When it is necessary to manually control the opening and closing of the exhaust port, the rotation of the transmission shaft 19 can be driven by rotating the turntable 22. At this time, the pulley 20 rotates accordingly, and the traction rope 21 wound on the pulley 20 can be retracted and released. At this time, the movable seat 12 can be driven to move up and down under the drive of the traction rope 21 to realize the opening and closing of the baffle 6.

[0030] Working principle: when the manual-automatic integrated air intake and exhaust control system of the AC generator set is in use, the linear motor 4 can be turned on to drive the movable seat 12 to move up and down, thereby driving the movable plate 11 and the movable block 9 to move up and down. At this time, the movable block 9 can be displaced relative to the movable slot 2 to drive the four push rods 8 at the bottom to move up and down, and finally drive the baffle 6 to move up and down to realize the opening and closing of the exhaust port. At the same time, the buffer springs 10 located at the upper and lower ends of the movable block 9 can provide buffering and reset when under pressure. When the movable seat 12 is driven to move by the linear motor 4, the movable block 9 is located in the limit slot at this time. The connecting rod 15 inside the limiting groove 3 is then displaced inside the limiting groove 3. When the movable seat 12 reaches a predetermined height, the threaded sleeves 17 on the threaded rods 16 at both ends can be rotated to drive the threaded sleeves 17 to move relative to the threaded rods 16, so that the threaded sleeves 17 are locked with the housing 1 to prevent the movement of the connecting rod 15. When the opening and closing of the exhaust port needs to be manually controlled, the rotation of the transmission shaft 19 can be driven by rotating the turntable 22. At this time, the pulley 20 rotates accordingly, and the traction rope 21 wound on the pulley 20 can be retracted and released. At this time, the movable seat 12 can be driven to move up and down under the drive of the traction rope 21 to realize the opening and closing of the baffle 6.
