[0002] In many low-temperature environments or working conditions with special requirements for intake air temperature, low engine intake temperature can cause a series of problems. For example, low-temperature intake air can cause poor fuel atomization and incomplete combustion, which in turn reduces the engine's power output, increases fuel consumption, and worsens emissions. Traditional intake air heating methods often require additional energy consumption, such as the use of electric heating elements, which not only increases energy costs but may also be affected by power supply stability. During operation, the generator will produce a large amount of high-temperature exhaust gas, which is usually discharged directly into the atmosphere, resulting in a waste of heat energy.

A positioning sleeve 336 is installed on the side wall of the sleeve 2, and a baffle 334 is slidably set inside the positioning sleeve 336. The baffle 334 and the push rod 33 are mutually connected, and the push rod 33 and the positioning sleeve 336 are movably penetrated. The side wall of the push rod 33 located inside the positioning sleeve 336 is sleeved with an extrusion spring 335, one end of the extrusion spring 335 is clamped on the inner wall of the positioning sleeve 336, and the other end is clamped on the baffle 334. When the notch 341 on the turntable 34 corresponds to the push rod 33, the push rod 33 is driven to retract inward by the extrusion spring 335, and then the push rod 33 as a whole slides along the limit seat 333, and the synchronous plate 331 at the end of the push rod 33 drives the slide bar 332 to slide, and the slide bar 332 slides in the strip groove 324 of the rocker arm 323 at this time, and finally can drive the rocker arm 323 to deflect, and the rocker arm 323 drives the synchronous shaft 32 to rotate on the fixed seat 322.

[0032] Embodiment 3: Based on Embodiment 2, the difference between this embodiment and the present embodiment is as follows: Figure 3 and Figure 4 As shown, in a specific embodiment, a limit rod 4 is installed inside the chute 313, the limit rod 4 is arc-shaped, the limit rod 4 and the slider 312 are movably connected, a tension spring 41 is sleeved on the limit rod 4, one end of the tension spring 41 is connected to the end surface of the chute 313, and the other end of the tension spring 41 is connected to the side wall of the slider 312, and a guide wheel 421 is installed at the end of the scraper 3, and the guide wheel 421 is connected to the protrusion 42 in a rolling manner. During the sliding process of the scraper 3, the guide wheel 421 on the scraper 3 will slide along the protrusion 42, and when the guide wheel 421 and the protrusion 42 are not in contact, the entire scraper 3 is driven to deflect by the tension spring 41, and the scraper 3 is reciprocatingly deflected in the air intake pipe 1 at this time, and the moving scraper 3 improves the particle cleaning quality of the outer wall of the air intake pipe 1 as a whole, and further improves the heating efficiency.

[0033] The present invention also discloses a heating method for an intake air heating device of a diesel generator set, the steps of which are as follows: Step 1: Start the diesel generator set, which draws gas into the device from the air intake pipe 1 and discharges the generated exhaust gas to the outside through the exhaust pipe 124; Step 2: With continuous operation, the high-temperature exhaust gas enters the inner cavity of the outer cover 12 through the exhaust pipe 124, and the inner cavity of the outer cover 12 is connected to the side wall of the intake pipe 1, so that the high-temperature exhaust gas heats the side wall of the intake pipe 1, thereby heating the intake air flowing through the intake pipe 1, so that the diesel of the diesel generator set is fully burned; Step 3: Drive the blocking block 232 to rotate. When the blocking block 232 blocks the diagonal outlet 221, the chamber corresponding to the outlet 221 is in a preliminary sealed state, thereby increasing the heat exchange time and the heating effect. The corresponding chamber is in a diagonal position, thereby uniformly heating the gas in the intake pipe 1. The chamber corresponding to the unblocked outlet 221 is in a mutually ventilated state, which is convenient for the normal discharge of exhaust gas and will not affect the normal use of the diesel generator set. Step 4: During the rotation of the blocking block 232, the coaxial turntable 34 rotates synchronously. After the notch 341 of the turntable 34 contacts the push rod 33, the push rod 33 retracts inward, and then the synchronous plate at the end of the push rod 33 drives the rocker arm 323 to deflect, and the rocker arm 323 drives the synchronous shaft 32 to rotate, and the top sleeve 31 at the bottom of the synchronous shaft 32 rotates. The top sleeve 31 drives the scraper 3 to slide on the outside of the intake pipe 1 through the top rod 311. The scraper 3 cleans the particles settled in the exhaust gas on the intake pipe 1, thereby improving the heat exchange efficiency and the heating effect. Step 5: During the sliding process of the scraper 3, the scraper 3 slides along the protrusion 42, and the protrusion 42 guides the scraper 3 to reciprocate around the intake pipe 1, so that the moving scraper 3 improves the particle cleaning quality of the outer wall of the intake pipe 1 and further improves the heating effect.

[0034] The implementation principle of a diesel generator set intake air heating device and heating method of the present invention is as follows: The operator needs to start the diesel generator set first. The diesel generator set will suck gas into the equipment from the intake pipe 1 and discharge the generated exhaust gas to the outside through the exhaust pipe 124. As the diesel generator set continues to run, the high-temperature exhaust gas enters the inner cavity of the outer cover 12 through the exhaust pipe 124, and the inner cavity of the outer cover 12 is interconnected with the side wall of the intake pipe 1, and then the high-temperature exhaust gas heats the side wall of the intake pipe 1, thereby heating the intake air flowing through the intake pipe 1, so that the diesel of the diesel generator set is fully burned.

[0035] Then the operator needs to start the driving motor 23, and the driving motor 23 drives the driving shaft 231 connected to the output end to rotate, and the driving shaft 231 drives the driving blocking block 232 to rotate. When the blocking block 232 rotates to the surface of the air outlet 221 on one side, the two chambers corresponding to the air outlet 221 are in a preliminary sealed state, thereby increasing the heat exchange time and the heating effect. The two corresponding chambers are in a diagonal position, so various positions on the side wall of the intake pipe 1 can be heated to avoid heating at a single position affecting the heating uniformity of the gas inside the intake pipe 1. At this time, the chamber corresponding to the air outlet 221 that is not blocked by the blocking block 232 is in a state of mutual circulation, which is convenient for the normal discharge of exhaust gas and will not affect the normal use of the diesel generator set. At this time, the blocking block 232 rotates continuously, thereby continuously switching the states of different chambers, which is convenient for improving the heating efficiency.

[0036] When the drive shaft 231 rotates, the drive shaft 231 can drive the turntable 34 to rotate synchronously. When the notch 341 of the turntable 34 corresponds to the push rod 33, the extrusion spring 335 inside the positioning sleeve 336 squeezes the baffle plate 334 to slide inside the positioning sleeve 336, pushing the push rod 33 to slide, ensuring that the push rod 33 is always in contact with the side wall of the turntable 34. Therefore, when the notch 341 on the turntable 34 corresponds to the push rod 33, the extrusion spring 335 drives the push rod 33 to retract inward, and then the push rod 33 as a whole slides along the limit seat 333, and the synchronous plate 331 at the end of the push rod 33 drives the slide bar 3 The sliding bar 332 slides in the strip groove 324 of the rocker arm 323 at this time, and can finally drive the rocker arm 323 to deflect, and the rocker arm 323 drives the synchronous shaft 32 to rotate on the fixed seat 322, and the synchronous shaft 32 drives the top sleeve 31 at the bottom to rotate through the connecting seat 321, and the top sleeve 31 drives the scraper 3 to slide on the outside of the intake pipe 1 through the push rod 311, and the scraper 3 can clean the particles settled in the exhaust gas on the intake pipe 1, thereby improving the heat exchange efficiency and the heating effect, and in this process, the push rod 311 slides inside the top sleeve 31 to ensure that the scraper 3 can slide smoothly.

[0037] During the sliding of the scraper 3, the guide wheel 421 on the scraper 3 will slide along the protrusion 42. When the guide wheel 421 and the protrusion 42 are not in contact, the entire scraper 3 is driven to deflect by the tension spring 41, and the scraper 3 deflects back and forth in the intake pipe 1 at this time. The moving scraper 3 improves the particle cleaning quality of the outer wall of the intake pipe 1 as a whole, and further improves the heating effect. In the process of the deflection of the scraper 3, the slide groove 313 on the scraper 3 slides on the surface of the slider 312, and the limit rod 4 on the slide groove 313 also slides on the surface of the slider 312 at this time. The above structures all serve the purpose of guidance.

[0038] At this time, the cleaned dust will fall into the waste hopper 125. Later, the dust can be cleaned by removing the sealing plug 126 at the bottom of the waste hopper 125 to ensure the normal operation of the heating device.

10. A method for heating intake air of a diesel generator set, characterized in that: The method for heating the diesel generator set air intake according to any one of claims 1 to 9 is as follows: Step 1: starting the diesel generator set, the diesel generator set sucks gas into the device through the intake pipe (1), and discharges the generated exhaust gas to the outside through the exhaust pipe (124); Step 2: As the operation continues, high-temperature exhaust gas enters the inner cavity of the outer cover (12) through the exhaust pipe (124), and the inner cavity of the outer cover (12) is connected to the side wall of the intake pipe (1), so that the high-temperature exhaust gas heats the side wall of the intake pipe (1), thereby heating the intake air flowing through the intake pipe (1), so that the diesel of the diesel generator set is fully burned; Step 3: driving the blocking block (232) to rotate, when the blocking block (232) blocks the outlet (221) located at the diagonal line, the chamber corresponding to the outlet (221) is in a preliminary sealed state, thereby increasing the heat exchange time and the heating effect, and the corresponding chamber is in a diagonal position, thereby uniformly heating the gas in the intake pipe (1), and the chamber corresponding to the outlet (221) that is not blocked is in a mutually flowing state, which is convenient for the normal discharge of exhaust gas and will not affect the normal use of the diesel generator set; Step 4: During the rotation of the blocking block (232), the coaxial rotating disk (34) rotates synchronously. After the notch (341) of the rotating disk (34) contacts the push rod (33), the push rod (33) retracts inward, and then the synchronous plate at the end of the push rod (33) drives the rocker arm (323) to deflect, and the rocker arm (323) drives the synchronous shaft (32) to rotate, and the top sleeve (31) at the bottom of the synchronous shaft (32) rotates. The top sleeve (31) drives the scraper (3) to slide on the outside of the intake pipe (1) through the top rod (311). The scraper (3) cleans the particles settled in the exhaust gas on the intake pipe (1), thereby improving the heat exchange efficiency and the heating effect. Step 5: During the sliding process of the scraper (3), the scraper (3) slides along the protrusion (42), and the protrusion (42) guides the scraper (3) to reciprocate around the air intake pipe (1), thereby improving the particle cleaning quality of the outer wall of the air intake pipe (1) by the moving scraper (3), further improving the heating effect.
