Description

Technical Field

[0001] The utility model belongs to the technical field of generator sets, and in particular relates to an exhaust gas discharge structure on the top of a generator box. Background Art

[0002] There are two main types of natural gas generator sets: one is a combined cycle gas turbine and the other is a gas internal combustion engine. Gas turbines have relatively large power and are mainly used in large and medium-sized power stations, while gas internal combustion engines have relatively small power and are mainly used in small distributed power stations. It is a new type of green and environmentally friendly power to replace oil and coal-fired units. It makes full use of various natural gases or harmful gases as fuel, turns waste into treasure, operates safely and conveniently, has high cost-effectiveness, low emission pollution, and is suitable for combined heat and power generation.

[0003] The existing gas unit includes a generator and an engine. The engine generates energy by burning natural gas or other gases and enables the generator to generate electricity. The engine generates heat when working, which causes the temperature inside the box where the gas unit is placed to rise. However, the engine requires a suitable temperature when working to achieve maximum performance. When the engine is working, the exhaust port will emit hot exhaust gas. If the exhaust gas is directly discharged outside the box, the noise is relatively large. Therefore, a muffler is required to treat the exhaust gas. Most of the current mufflers are fixed and installed with bolts. It is troublesome to disassemble, clean and replace the muffler. Therefore, a generator box top exhaust gas discharge structure is needed to solve the above problems. Utility Model Content

After the arc block 21 is completely retracted back into the arc groove 20, the operator rotates the muffler 10 to make the arc block 17 snap into the annular cavity 14. Under the elastic action of the spring 22, the arc block 21 extends out of the arc groove 20, the square block 16 abuts against the side wall of the vertical opening, so that the arc block 17 snaps into the annular cavity 14, and the arc block 21 limits the arc block 17, thereby limiting the muffler 10, which is convenient for quick installation;

[0025] When the utility model needs to be disassembled, the user pulls the round rod 24, and the round rod 24 drives the arc block 21 to move, so that the spring 22 is compressed. After the arc block 21 shrinks into the arc groove 20, the operator rotates the muffler 10, and the muffler 10 drives the arc block 17 to rotate through the square block 16. After the arc block 17 is rotated to align with the arc opening 15, the operator pulls the muffler 10 to the outside of the round groove 13, so that the muffler 10 is removed. The muffler 10 can be quickly disassembled, which is convenient for cleaning and replacement of the muffler 10;

[0026] Furthermore, a pull plate is fixed to the two round rods 24 on the same side. The operator pulls the pull plate to operate the two arc blocks 21 at the same time, which improves the convenience of use of the device.

[0027] The utility model extends the arc-shaped clamping block on the side wall of the muffler into the arc-shaped opening, rotates the muffler, clamps the arc-shaped clamping block into the annular cavity, and a spring controls the arc-shaped block to limit the muffler, thereby installing the muffler. The utility model is convenient to use and has a simple structure.
