Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to an overload protection device for a high-pressure air intake chamber. Background Art

[0002] When the gas engine is in use, air is taken in through the air intake chamber, that is, the outside air is absorbed into the air intake chamber through the air intake chamber for compression and use.

[0003] The utility model with patent application number 202222541259.X discloses an intake chamber pressure difference high protection device, including a mounting mechanism, the mounting mechanism including a slide plate and teeth, the slide plate is provided with two groups, and the slide plates are arranged on both sides of the main body in the mounting mechanism, and the slide plate is slidably installed in the slide groove at the outer end of the main body, and the teeth are arranged at the front position of the outer end of the slide plate; the mounting mechanism is provided with an adjustment component, and the mounting frame of the adjustment component is arranged at the bottom of the main body, and the two sides of the mounting frame are engaged with the two ends of the main body, and slide plates are slid in the side grooves on both sides of the mounting frame, and the teeth on the slide plate are meshed with the gears in the side grooves, and the mounting mechanism is provided with an external component, and the shell of the external component is arranged in the middle position of the upper end of the main body, and the shell is connected to the main body.

[0004] The air intake chamber high pressure difference protection device can adjust the size of the opening of the through holes on both sides of the main body (that is, when the left through hole becomes larger, the right through hole becomes smaller). Through such a setting, the air pressure in the air intake chamber can be adjusted to prevent the air pressure in the air intake chamber from being too extreme and causing danger. However, there are still areas that can be improved. For example, the air pressure adjustment in the air intake chamber requires manual operation to take effect, which is not convenient for practical application. In addition, the device cannot adjust the maximum working pressure, which makes it poorly applicable and unable to meet current needs. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-4 The utility model provides a technical solution: a high-pressure air intake chamber overload protection device, including a main body 1, an adjusting device 2, and a pressure relief device 3, the adjusting device 2 is arranged inside the main body 1, and the pressure relief device 3 is arranged on the side of the main body 1.

[0026] The adjusting device 2 is composed of a fixed block 201, a guide block 202, a connecting rod 203, a fixing frame 204, and a first spring 205. The fixed block 201 is fixedly installed inside the main body 1, the fixing frame 204 is fixedly installed inside the main body 1, the connecting rod 203 is slidably installed inside the fixing frame 204, the guide block 202 is fixedly installed on the side of the connecting rod 203, and a vent is opened on the surface of the fixed block 201. The guide block 202 is truncated cone-shaped, and the vent matches the guide block 202. This setting enables the guide block 202 to move in the vent. The first spring 205 is sleeved on the surface of the connecting rod 203. One end of the first spring 205 is connected to the guide block 202, and the other end is connected to the fixing frame 204. This setting can adjust the guide block 202 through the first spring 205. For resetting, the fixed block 201, the guide block 202, the fixed frame 204, and the first spring 205 are all one in a group, and there are two groups symmetrically arranged on the surface of the connecting rod 203. There are two groups of this component, when the guide block 202 on one side of the vent moves, the connecting rod 203 can drive the guide block 202 on the other side to move in the same direction, and the air volume of the vent can be actively adjusted. Through this arrangement, the air pressure in the main body 1 can be adjusted to prevent the air pressure in the main body 1 from being too extreme and dangerous. In the natural state, the guide block 202 of the first spring 205 is inside the fixed block 201. When the first spring 205 is compressed to the maximum, the guide block 202 is separated from the fixed block 201. This arrangement is convenient for controlling the amount of gas entering the main body 1 according to the air pressure.

[0027] The pressure relief device 3 is composed of a housing 301, a first piston 302, an inner sleeve 303, an outer sleeve 304, a second spring 305, a second piston 306, a bearing 307, a threaded rod 308, and a rotating handle 309. The housing 301 is bolted to the side of the main body 1. A leak hole is provided on the side of the housing 301, through which the high-pressure gas can be relieved. The first piston 302 is slidably mounted inside the housing 301, the inner sleeve 303 is fixedly mounted on the top of the first piston 302, the outer sleeve 304 is sleeved on the outside of the inner sleeve 303, the second spring 305 is fixedly mounted inside the outer sleeve 304, and the second spring 305 and the outer sleeve The other end of the connection 304 is connected to the inner sleeve 303. This setting can reset the inner sleeve 303 through the second spring 305. The second piston 306 is fixedly installed on the top of the outer sleeve 304, the bearing 307 is fixedly installed inside the second piston 306, and the threaded rod 308 is fixedly installed inside the bearing 307. A threaded hole is provided on the top of the shell 301 and matches the threaded rod 308. This setting can adjust the maximum working pressure of the device by rotating the rotating handle 309 so that the threaded rod 308 drives the second piston 306 to move up and down inside the shell 301. The rotating handle 309 is fixedly installed on the top of the threaded rod 308.

[0028] During use, when the air flow rate of the vent changes, the guide block 202 can move in the vent, and the connecting rod 203 drives the guide block 202 on the other side to move in the same direction, so as to actively adjust the air volume of the vent. Through such a setting, the air pressure in the main body 1 can be adjusted to prevent the air pressure in the main body 1 from being too extreme and dangerous. When the air pressure in the main body 1 is too high, the gas pushes the first piston 302 to move upward. When the height of the first piston 302 is higher than the height of the leak hole, the gas can leak out through the leak hole to reduce the air pressure in the main body.
