Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation shells, in particular to a heat dissipation shell for a generator slip ring chamber. Background Art

[0002] The slip ring in the generator slip ring chamber is a key electrical device, whose main function is to transfer electrical energy from the stationary stator part to the rotating rotor part. During operation, the slip ring realizes the continuous connection between the rotating bodies and is responsible for transmitting energy and signals. In addition, the slip ring allows the current to be converted through the rotating sliding contact, thereby meeting the continuous conversion requirements of kinetic energy and electrical energy when the motor is running.

[0003] The generator slip ring chamber is a sealed chamber located at both ends of the generator rotor, usually made of cast iron. The function of the generator slip ring chamber is to prevent the lubricating oil and insulating oil in the slip ring from leaking out, and at the same time, it can also protect the slip ring, carbon brush and other components from being damaged by the external environment.

[0004] During operation, the slip rings and carbon brushes in the slip ring chamber will continuously generate heat due to friction. Excessive temperature accumulation can easily lead to damage to parts such as slip rings and carbon brushes. Therefore, corresponding measures need to be taken to keep their temperature within a normal range. Utility Model Content

[0023] 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.

[0024] A heat dissipation shell of a generator slip ring chamber comprises a slip ring chamber shell 1, a heat dissipation shell 2 is fixed to the outer end of the slip ring chamber shell 1, a base 3 is fixed to the bottom of the heat dissipation shell 2, and the base 3 plays a supporting role.

[0025] In this embodiment, Figure 2 and Figure 3 An air cooling mechanism 4 is arranged inside the heat dissipation shell 2. The air cooling mechanism 4 is arranged in two groups, and can simultaneously perform air cooling and heat dissipation from both sides of the slip ring chamber housing 1. A driving mechanism 6 is arranged below the air cooling mechanism 4, and the air cooling mechanism 4 can be driven by the driving mechanism 6. The air cooling mechanism 4 is composed of a rotating rod 41 and fan blades 42. The rotating rod 41 is rotatably connected to the outer side of the slip ring chamber housing 1, and is also rotatably connected to the inner wall of the heat dissipation shell 2. The fan blades 42 are evenly arranged on the outer side of the rotating rod 41, and the fan blades 42 are fixed to the rotating rod 41, and can drive the fan blades 42 to rotate when the rotating rod 41 rotates.

[0026] Further, such as Figure 1 and Figure 3 A second dustproof net 21 is fixed to one end of the heat dissipation shell 2 close to the air cooling mechanism 4, and a first dustproof net 11 is fixed to one side of the slip ring chamber housing 1 close to the air cooling mechanism 4, so that when the air cooling mechanism 4 rotates as a whole, the external airflow can enter the heat dissipation shell 2 from the second dustproof net 21, and then enter the interior of the slip ring chamber housing 1 through the first dustproof net 11, and the slip ring chamber housing 1 is cooled and dissipated by the introduced airflow.

[0027] Specifically, Figure 2The driving mechanism 6 consists of a driving motor 61 and a driving rod 62. The driving motor 61 is installed at the bottom of the heat dissipation shell 2. The driving rod 62 is respectively connected to the output shafts on both sides of the driving motor 61. The specific connection method can adopt the existing technology, which can drive the driving rods 62 on both sides to rotate simultaneously when the driving rod 62 is started.

[0028] Furthermore, a first limiting ring 411 is fixed to the outer end of the rotating rod 41, and a second limiting ring 621 is fixed to the outer end of the driving rod 62, wherein the outer sides of the first limiting ring 411 and the second limiting ring 621 are sleeved with the same chain 7, and the chain 7 is respectively engaged with the first limiting ring 411 and the second limiting ring 621, so that when the driving rod 62 rotates, the rotation can be transmitted to the rotating rod 41 through the chain 7, thereby driving the rotating rod 41 to rotate at the same time.

[0029] In another embodiment, if Figure 2 and Figure 3 A baffle plate 5 fixed inside the heat dissipation shell 2 is provided below the rotating rod 41, and a plug hole is provided inside the baffle plate 5, through which the chain 7 can pass. The cavity space inside the heat dissipation shell 2 can be divided by the baffle plate 5, so that the cavity space where the air cooling mechanism 4 is located is smaller, so that the gas introduced into the heat dissipation shell 2 through the air cooling mechanism 4 is not easy to disperse, and more air flow is blown into the slip ring chamber housing 1, and the air cooling effect is better.

[0030] In this embodiment, Figure 1 , Figure 2 and Figure 4 A dustproof plate 8 is provided on the top of the slip ring chamber housing 1, and a third dustproof net 81 is fixed inside the dustproof plate 8, so that the airflow in the slip ring chamber housing 1 can be discharged through the third dustproof net 81. Fixing mechanisms 9 are respectively provided on both sides of the dustproof plate 8, and the dustproof plate 8 can be fixed by the fixing mechanism 9. The fixing mechanism 9 consists of a movable block 91, a clamping block 92 and a return spring 93. The movable block 91 is slidably connected to the inside of the slip ring chamber housing 1, wherein one end of the movable block 91 extends to the outside of the slip ring chamber housing 1, and a clamping block 92 is fixed on the end of the movable block 91 close to the dustproof plate 8. The return spring 93 is fixed on the end of the clamping block 92 away from the dustproof plate 8, and the other end of the return spring 93 is fixed to the inside of the slip ring chamber housing 1. Under the pushing action of the return spring 93 on the movable block 91, the movable block 91 can be used to drive the clamping block 92 to slide, and then the clamping block 92 is clamped with the dustproof plate 8, so that the dustproof plate 8 can be fixed on the top of the slip ring chamber housing 1.

[0031] Furthermore, a sealing gasket 82 is attached to the lower end of the dustproof plate 8, so that when the block 92 clamps the dustproof plate 8, the sealing gasket 82 fits against the slip ring chamber housing 1 to maintain the sealing of the connection between the dustproof plate 8 and the slip ring chamber housing 1.

[0032] When the temperature in the slip ring chamber housing 1 needs to be lowered, the drive motor 61 is first started to drive the drive rod 62 to rotate. When the drive rod 62 rotates, the rotating rod 41 can be driven to rotate through the chain 7. At this time, the fan blades 42 inhale the external airflow through rotation, and introduce the airflow into the slip ring chamber housing 1 for heat dissipation. Another part of the airflow in the slip ring chamber housing 1 is discharged from the movable block 91.

[0033] When the movable block 91 needs to be cleaned, first press the movable blocks 91 on both sides at the same time, so that the movable block 91 drives the clamping block 92 to move. When the clamping block 92 is no longer clamped with the dustproof plate 8, the dustproof plate 8 can be removed from the slip ring chamber housing 1 and the third dustproof net 81 can be cleaned.
