Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to a waste heat generator for light hydrocarbon plants that is easy to maintain online. Background Technology

[0002] A generator is a rotating electrical machine that converts mechanical energy into electrical energy, driven by a prime mover (providing mechanical energy) based on the principle of electromagnetic induction. It is a key terminal device that ultimately converts various primary energy sources in nature into readily usable secondary energy—electricity.

[0003] Traditional brushed excitation generator sets, limited by the existing conductive ring structure, have carbon brush terminal fixing screws positioned too close to the generator rotor (<2.5mm). Replacing carbon brushes while the unit is running poses a very high safety risk, necessitating a shutdown for replacement. This operation requires coordination among multiple departments, including utilities and upstream / downstream equipment, making the process complex, time-consuming, and labor-intensive, resulting in some power generation loss. Furthermore, the bolts used for fixing the carbon brushes are prone to stripping due to repeated loosening and tightening, leading to terminal detachment and power generation failure. Frequent generator shutdowns caused solely for carbon brush replacement severely disrupt the safe, stable, and orderly operation of steam and electricity supply. Utility Model Content

[0004] Addressing the technical problem that existing waste heat generators frequently shut down due to carbon brush replacement, severely disrupting the safe, stable, and orderly operation of steam and electricity supply, this utility model proposes a waste heat generator for light hydrocarbon plants that is easy to maintain online.

[0005] This utility model proposes a waste heat generator for a light hydrocarbon plant that is easy to maintain online, including a generator housing, and a carbon brush device is provided on the outer surface of the generator housing. The carbon brush device includes a carbon brush component and a fixing component.

[0006] The carbon brush component includes a carbon brush that transmits current, and the fixing component includes a fixing block that fixes the carbon brush component.

[0007] Preferably, the carbon brush component includes a slip ring with an outer arc radius of 349 mm and an inner arc radius of 229 mm. The slip ring is fixedly mounted on the outer surface of the generator housing. A brush box is fixedly mounted on the outer surface of the slip ring. A spring clip is slidably inserted into the inner wall of the brush box. The outer surface of the carbon brush is slidably inserted into the inner wall of the brush box, and the spring clip is in contact with the outer surface of the carbon brush.

[0008] Preferably, a flexible connector is fixedly mounted on the outer surface of the carbon brush, and a terminal block is fixedly mounted on the outer surface of the flexible connector, with the terminal block in contact with the outer surface of the slip ring.

[0009] Preferably, the fixing component further includes a threaded sleeve, the outer surface of which is threadedly connected to the inner wall of the threaded hole of the slip ring, and one end of the threaded sleeve is threadedly connected to an insulating shell.

[0010] Preferably, a track block is fixedly installed on the inner wall of the insulating shell, a movable block is slidably inserted into the inner wall of the insulating shell via a limiting rod, a rocker arm is hinged to the outer surface of the movable block via a pin, the outer surface of the rocker arm is slidably connected to the outer surface of the track block, and a connecting spring is fixedly installed on the inner wall of the movable block, one end of the connecting spring being fixedly installed to the inner wall of the insulating shell.

[0011] Preferably, a push handle is slidably inserted into the inner wall of the insulating shell, and a spring locking block is fixedly installed on the outer surface of the movable block. The outer surface of the spring locking block is slidably connected to the inner wall of the insulating shell, and the outer surface of the push handle is slidably connected to the outer surface of the spring locking block.

[0012] Preferably, a control handle is slidably inserted into the inner wall of the threaded sleeve, one end of the control handle is threadedly connected to one end of the push handle, a push plate is fixedly installed on the outer surface of the control handle, the outer surface of the push plate is slidably inserted into the inner wall of the threaded sleeve, a return spring is fixedly installed on the outer surface of the push plate, a pressure plate is fixedly installed on the outer surface of the return spring, and the inner wall of the pressure plate is slidably inserted into the outer surface of the threaded sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] By setting fixed components, the terminals can be quickly fixed. The movement of the moving block causes the crank to deflect on the surface of the track block, thus fixing the crank to the track block. To push the moving block, the spring locking block can lock itself to the moving block. One end of the spring locking block is fixed to the moving block by a spring plate, which allows the spring locking block to deflect under the pressure of the insulating shell as the moving block moves. After inserting the push handle, the push handle is fixed, thereby limiting the position of the pressure plate and making the pressure plate contact the outer surface of the terminal. The return spring increases the pressing force of the pressure plate on the terminal. This solves the technical problem of frequent shutdowns of existing waste heat generators due to carbon brush replacement, which seriously interferes with the safe, stable, and orderly operation of steam and electricity supply.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7 A waste heat generator for a light hydrocarbon plant that is easy to maintain online includes a generator housing 1, and a carbon brush device is provided on the outer surface of the generator housing 1. The carbon brush device includes carbon brush components and fixing components.

[0025] The carbon brush component includes a carbon brush 23, which transmits current. The fixing component includes a pressure plate 43, which fixes the carbon brush component by moving.

[0026] Specifically, the carbon brush component includes a slip ring 2, with an outer arc radius of 349mm and an inner arc radius of 229mm. To avoid modifications to the generator body, the bolt holes for fixing the slip ring to the generator body remain unchanged. The slip ring body is widened by 149mm to ensure sufficient space for fixing the carbon brush 23 lead wire when it is moved outward. The carbon brush 23 lead wire fixing hole is moved outward to ensure sufficient safety clearance. The clearance is moved outward by 73.5mm from the original clearance to eliminate stress concentration in the lead wire and prevent surface discharge. The slip ring 2 is fixedly installed on the outer surface of the generator housing 1. A brush box 21 is fixedly installed on the outer surface of the slip ring 2. A spring clip 22 is slidably inserted into the inner wall of the brush box 21. The outer surface of the carbon brush 23 is slidably inserted into the inner wall of the brush box 21, and the spring clip 22 contacts the outer surface of the carbon brush 23. The spring clip fixes the carbon brush 23 and simultaneously pushes the carbon brush 23 to maintain contact with the rotor.

[0027] Specifically, a flexible connector 24 is fixedly mounted on the outer surface of the carbon brush 23, and a terminal block 25 is fixedly mounted on the outer surface of the flexible connector 24. The terminal block 25 contacts the outer surface of the slip ring 2; an electrical connection can be made between the flexible connector 24 and the terminal block 25 and the slip ring 2.

[0028] Specifically, the fixing component also includes a threaded sleeve 3. The inner wall of the threaded sleeve 3 can be provided with an insulating layer to facilitate operation of the threaded sleeve 3 and reduce the risk of electric shock. The outer surface of the threaded sleeve 3 is threadedly connected to the inner wall of the threaded hole of the slip ring 2. One end of the threaded sleeve 3 is threadedly connected to an insulating shell 31. In order to position the pressure plate 43, the threaded sleeve 3 is threadedly connected to the slip ring 2, which facilitates the pressure plate 43 to press the terminal 25 and fix the terminal 25.

[0029] Specifically, a track block 32 is fixedly installed on the inner wall of the insulating shell 31, and a movable block 33 is slidably inserted into the inner wall of the insulating shell 31 through a limiting rod. A rocker arm 34 is hinged to the outer surface of the movable block 33 through a pin, and the outer surface of the rocker arm 34 is slidably connected to the outer surface of the track block 32. In order to facilitate the reset of the movable block 33, a connecting spring 35 is fixedly installed on the inner wall of the movable block 33, and one end of the connecting spring 35 is fixedly installed to the inner wall of the insulating shell 31. By moving the movable block 33, the rocker arm 34 can be deflected on the surface of the track block 32, so that the rocker arm 34 is fixed on the track block 32, thereby limiting the movable block 33. The connecting spring 35 facilitates the reset of the movable block 33.

[0030] Specifically, a push handle 36 is slidably inserted into the inner wall of the insulating shell 31, and a spring locking block 37 is fixedly installed on the outer surface of the moving block 33. The outer surface of the spring locking block 37 is slidably connected to the inner wall of the insulating shell 31, and the outer surface of the push handle 36 is slidably connected to the outer surface of the spring locking block 37. In order to push the moving block 33 to move, and at the same time, the spring locking block 37 can lock with the moving block 33. One end of the spring locking block 37 is fixed to the moving block 33 through a spring plate, so that the spring locking block 37 can be deflected by the pressure of the insulating shell 31 as the moving block 33 moves. After the push handle 36 is inserted, the push handle 36 is fixed, thereby limiting the position of the pressure plate 43, so that the pressure plate 43 contacts the outer surface of the terminal 25.

[0031] Specifically, a control handle 4 is slidably inserted into the inner wall of the threaded sleeve 3. One end of the control handle 4 is threadedly connected to one end of the push handle 36. A push plate 41 is fixedly installed on the outer surface of the control handle 4. The outer surface of the push plate 41 is slidably inserted into the inner wall of the threaded sleeve 3. A return spring 42 is fixedly installed on the outer surface of the push plate 41. A pressure plate 43 is fixedly installed on the outer surface of the return spring 42. The inner wall of the pressure plate 43 is slidably inserted into the outer surface of the threaded sleeve 3. By pushing the control handle 4, the push plate 41 can be moved. The push plate 41 moves the pressure plate 43 through the return spring 42. The control handle 4 and the push handle 36 are threadedly connected, which can push the moving block 33 to fix one end of the push handle 36. Thus, the pressure plate 43 can press the terminal 25, which facilitates quick disassembly and reduces contact time.

[0032] By setting a fixing component, the terminal 25 can be quickly fixed. The movement of the moving block 33 can drive the rocker 34 to deflect on the surface of the track block 32, so that the rocker 34 is fixed on the track block 32. In order to push the moving block 33 to move, the spring locking block 37 can lock with the moving block 33. One end of the spring locking block 37 is fixed to the moving block 33 through the spring plate, so that the spring locking block 37 can be deflected by the pressure of the insulating shell 31 as the moving block 33 moves. After the push handle 36 is inserted, the push handle 36 is fixed, thereby limiting the position of the pressure plate 43, so that the pressure plate 43 contacts the outer surface of the terminal 25. The return spring 42 increases the pressing force of the pressure plate 43 on the terminal 25, which solves the technical problem that the existing waste heat generator frequently stops due to the replacement of carbon brush 23, which seriously interferes with the safe, stable and orderly operation of production steam supply and power supply.

[0033] Working principle: When it is necessary to replace the carbon brush 23, a flathead screwdriver or a tool with a flathead protrusion is inserted into the groove of the control handle 4. The control handle 4 is pushed to move within the threaded sleeve 3. The push plate 41 on the control handle 4 compresses the return spring 42. After the control handle 4 pushes the threaded push handle 36 to move, the push handle 36 pushes the inserted moving block 33 to move within the insulating housing 31. The moving block 33 drives the rocker handle 34 to slide on the outer surface of the track block 32. The connecting spring 35 returns to its original position, thus... The crank handle 34 is located on one side of the track block 32, which facilitates the fixation of the moving block 33 next time. After the spring lock block 37 on the moving block 33 moves, it is released from the limitation of the insulating shell 31. The spring lock block 37 is reset under the action of the spring plate. After contacting the fixation of one end of the push handle 36, the control handle 4 can move outward under the action of the reset spring 42. After contacting the pressing of the pressure plate 43, the pressure plate 43 contacts the fixation of the terminal 25. After pulling out the spring buckle 22 in the brush box 21, the carbon brush 23 can be taken out.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
