Description

Technical Field

[0001] The utility model relates to the field of generator monitoring, in particular to a monitoring trolley for an air cooler in a wind tunnel of a generator set. Background Art

[0002] Each generator set has multiple air coolers evenly arranged along the circumference of the generator in a closed wind tunnel, and cooling water flows through the air coolers. The wind generated during the operation and rotation of the generator set passes through the generator and the air cooler in turn, and the cold air after the air cooler re-enters the generator to cool the unit. Water leakage may occur during the operation of the generator air cooler, and personnel are required to conduct regular inspections. If it is not discovered, the generator set will be filled with water, causing the equipment to stop operating and causing a lot of economic losses. For this reason, we propose an air cooler monitoring cart in the wind tunnel of the generator set to solve the above problems. Utility Model Content

According to this structure, the main shaft and rotor of the generator blow out wind, a plurality of air coolers 1 are installed on the outer wall of the generator, and the guide rail 3 is installed around the generator. The cylinder 406 is driven to open the two sails 404 under the action of the spring 405, so that the wind blown out by the generator blows the sails 404, so that the trolley 2 slides along the guide rail 3. The water receiving device 5 moves to the bottom of the water guide column 103. When the air cooler 1 leaks, the water receiving device 5 catches the falling water on the water guide column 103, and the alarm on the water receiving device 5 sounds, indicating that there is a water leak in the air cooler 1. It is prevented that the generator set is filled with water, resulting in equipment shutdown and a large amount of economic losses. When the trolley 2 needs to be stopped for maintenance, the cylinder 406 is driven to retract the sail 404 so that the trolley 2 stops moving due to the friction force on the guide rail 3, which facilitates its maintenance.

[0023] In a preferred solution, a plurality of water receiving boxes 101 are provided on the air cooler 1, a water receiving tank body 102 is provided on the water receiving tank 101, a through hole 104 is provided on the water receiving tank body 102, and a hollow water guide column 103 is provided at the bottom of the through hole 104. With this structure, when the air cooler 1 leaks, part of the sewage will fall onto the water receiving box 101 and fall along the water guide column 103 on the water receiving tank body 102, and when the trolley 2 moves to the leaking air cooler 1, the sewage will flow to the water receiving device 5.

[0024] In the preferred solution, the inner and outer sides of the guide rail 3 are provided with chutes 301, an annular water tank 302 is provided between the two chutes 301, a threaded hole 303 is provided on one side of the water tank 302, and a threaded bolt 304 is provided on the threaded hole 303. With this structure, when the air cooler 1 does not leak much water, the valve on the box 203 is opened to allow the water stored on the box 203 to flow to the guide rail 3, the bolt 304 is turned, and a sewage recovery tank is placed at the threaded hole 303 to allow the sewage in the water tank 302 to be discharged from the guide rail 3.

[0025] In a preferred solution, the trolley 2 includes a vehicle plate 201, on which a hollow box 203 and a plurality of rollers 202 are provided, and the rollers 202 roll against the slide groove 301. With this structure, a valve is provided on the box 203, and when the air cooler 1 does not leak much water, the valve on the box 203 is opened to allow the water stored in the box 203 to flow onto the guide rail 3.

[0026] In a preferred solution, the water receiving device 5 includes a water receiving tray 501 and a hollow water bucket 502, one end of the water bucket 502 is connected to the water receiving tray 501, and the other end of the water bucket 502 is connected to the box 203. With this structure, the water receiving tray 501 has a larger area than the water bucket 502, and can receive the sewage falling from the water guide column 103 in a large area. The water receiving tray 501 is connected to the water bucket 502, and the water bucket 502 is connected to the box 203, so that the sewage flows to the box 203, avoiding the falling water affecting the monitoring of the next air cooler 1.

[0027] In a preferred solution, the power device 4 includes a column 401, two rotating shafts 402 are provided on the column 401, a mast 403 is provided on the rotating shaft 402, a sail 404 is provided between the mast 403 and the column 401, and a second spring 405 is provided between the rotating shaft 402 and the column 401. According to this structure, the cylinder 406 is driven to move the cable 408 along the rolling wheel 407, so that the two masts 403 are opened under the action of the spring 405, so that the masts 403 are opened, so that the wind blown by the generator blows the sail 404, so that the trolley 2 slides along the guide rail 3.

[0028] In a preferred solution, a cylinder 406 and two rolling wheels 407 are provided on the column 401, and the rolling wheel 407 is connected to the sail 404 through a cable 408. The cylinder 406 is connected to the rolling wheel 407 through a cable 408. A connecting seat is provided at the connection between the cable 408 and the mast 403, and the connecting seat slides on the mast 403. With this structure, the mast 403 is opened under the action of the spring 405 to open the sail 404, so that the power device 4 is moved by the wind blown out by the air cooler 1. When the cylinder 406 is contracted, the multiple masts 403 are retracted to shut down the power device 4. A connecting seat is provided at the connection between the cable 408 and the mast 403, and the connecting seat slides on the mast 403.

[0029] In the preferred solution, a water level sensor and an alarm are provided on the water receiving device 5, and the water level sensor is connected to the alarm. With this structure, when the air cooler 1 leaks, the water receiving device 5 catches the falling water on the water guide column 103, and the water level in the water receiving device 5 exceeds the threshold set by the water level sensor, so that the alarm sounds. This indicates that there is a water leak in the air cooler 1. This prevents the generator set from being filled with water, causing the equipment to stop operating and causing a large amount of economic losses.
