[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-4 As shown, an engine oil pipe penetration detection device includes:

[0024] A connecting shell 1 is fixedly connected to the end of the oil pipe. One end of the connecting shell 1 is provided with a detection cavity 102. An oil and gas detector 101 is provided inside the detection cavity 102.

[0025] Detection component 2, which is arranged inside the connecting shell 1 and is used to detect whether leakage occurs during the oil pipeline transportation process;

[0026] Sealing component 3, the sealing component 3 is used to improve the detection accuracy of the oil and gas detector 101;

[0027] The detection component 2 includes a groove 201 formed on the surface of the oil pipe, and a detection ball 205 is disposed inside the groove 201 .

[0028] like Figure 1-4 As shown, the bottom of the detection ball 205 fits against the inner wall of the groove 201 , the top of the detection ball 205 is fixedly connected with a buffer block 202 , the upper end of the buffer block 202 is fixedly connected to the inner wall of the connecting shell 1 , and a pressure sensor 203 is provided inside the buffer block 202 .

[0029] The top of the detection ball 205 is fixedly connected to a spring 204 , and the other end of the spring 204 is fixedly connected to the inner wall of the connection shell 1 .

[0030] The setting of the groove 201 can make the distance between the detection ball 205 and the fuel in the oil delivery pipe smaller, and the setting of the spring 204 enables the detection ball 205 to be close to the inner wall of the groove 201. As the pressure of the fuel delivered in the oil pipe changes, different pressures can be applied to the buffer block 202 through the detection ball 205, and then transmitted to the pressure sensor 203 through the buffer block 202. The pressure change is detected by the pressure sensor 203 and transmitted to the control terminal for comparison. The control terminal is not shown in the figure. It is used to receive and process the signals detected by the pressure sensor 203 and the oil and gas detector 101. The control terminal is a relatively mature component in the application of existing technology and will not be described in detail here.

[0031] The oil inlet and outlet ends of the oil delivery pipe are both provided with grooves 201. This arrangement can detect the pressure of the fuel delivered in the oil pipe from the oil inlet end, and compare whether the pressure on both sides changes when it is delivered to the oil outlet end. If there is a change, it means that a leakage has occurred during the pipeline transportation process.

[0032] like Figure 1 、 Figure 3 and Figure 4 As shown, the sealing assembly 3 includes a connecting sleeve 302 slidably connected to the surface of the connecting shell 1 , one end of the connecting sleeve 302 is fixedly connected to a pressure ring 301 , and a sealing airbag 308 is embedded and installed inside the pressure ring 301 .

[0033] A connecting ring 303 is fixedly connected to the surface of the connecting shell 1. The connecting ring 303 is located on the side of the connecting sleeve 302 away from the pressure ring 301. The interior of the connecting sleeve 302 is provided with uniformly distributed gas storage cavities 305, which are filled with inert gas.

[0034] The inner wall of the air storage cavity 305 is slidably connected to an extrusion plate 307 , and the surface of the extrusion plate 307 is fixedly connected to an adjustment rod 304 . The other end of the adjustment rod 304 passes through the connecting sleeve 302 and is fixedly connected to the surface of the connecting ring 303 .

[0035] The surface of the sealing airbag 308 is connected to evenly distributed connecting tubes 306 , and the other end of the connecting tube 306 is connected to the adjacent air storage cavity 305 .

[0036] During the process of connecting the oil pipe with other pipelines, such as the oil outlet of the engine fuel injection system, the pressure ring 301 can be close to the outer shell of the engine fuel injection system, and is blocked by it to drive the connecting sleeve 302 to slide along the surface of the connecting shell 1. In this process, it can drive the adjusting rod 304 to insert into the interior of the air storage chamber 305, thereby driving the extrusion plate 307 to squeeze the inert gas stored in the interior of the air storage chamber 305, so that the inert gas can be injected into the interior of the sealing airbag 308 through the connecting pipe 306 to make it bulge, until the oil pipe is tightly connected to the other pipelines, the sealing airbag 308 cooperates with the pressure ring 301 to seal the detection chamber 102, thereby ensuring that the volatilized gas when a leak occurs at the connection between the oil pipe and other pipelines can be detected in time by the oil and gas detector 101, thereby improving the detection accuracy of the oil and gas detector 101.

[0037] When the present invention is in use, the setting of the groove 201 can make the distance between the detection ball 205 and the fuel in the oil delivery pipe smaller, and the setting of the spring 204 enables the detection ball 205 to be close to the inner wall of the groove 201. As the pressure of the fuel delivered in the oil pipe changes, different pressures can be applied to the buffer block 202 through the detection ball 205, and then transmitted to the pressure sensor 203 through the buffer block 202. The pressure change is detected by the pressure sensor 203. This setting method can detect the pressure of the fuel delivered in the oil pipe from the oil inlet end, and compare whether the pressure on both sides changes when it is delivered to the oil outlet end. If there is a change, it can be seen that a leakage has occurred during the pipeline transportation process. By setting the sealing component 3, the overall sealing performance of the connection between the oil pipe and other pipelines can be improved, so that the volatilized gas can be detected in time by the oil and gas detector 101 when a leak occurs there, thereby improving the detection accuracy of the oil and gas detector 101.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
