The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0027] In related technologies, HPSCR emission systems installed on low-speed diesel engines require multiple differential pressure sensors to function properly. In existing technologies, differential pressure sensors are typically installed on pipes surrounding the emission system; however, low-speed diesel engines come in different types, and not every type can be installed on the pipes.

[0028] To improve the installation adaptability of differential pressure sensors, this application provides a mounting bracket for an SCR differential pressure sensor. The mounting bracket includes: a mounting plate bracket for mounting the differential pressure sensor; a mounting crossbar with multiple first mounting holes for mounting the mounting plate bracket; and at least two support mechanisms that clamp the mounting crossbar and are used to mount the bracket to the exhaust manifold of a diesel engine. By using the mounting bracket to mount the differential pressure sensor, the sensor can be isolated from the exhaust manifold based on the support mechanisms, thus preventing the sensor from being directly mounted to the exhaust manifold and improving its installation adaptability.

[0029] See Figures 1 to 5 In this embodiment, the mounting bracket may include a mounting plate bracket 100, a mounting crossbar 200, and at least two support mechanisms 300. The mounting plate bracket 100 can be used to mount a differential pressure sensor. The mounting crossbar 200 is provided with a plurality of first mounting holes 210, which can be used to mount the mounting plate bracket 100. Two or more support mechanisms 300 clamp the mounting crossbar 200, and the support mechanisms 300 can be used to mount the bracket to the exhaust manifold of a diesel engine. The mounting plate bracket 100 can be, for example, a... Figure 1The integral bracket shown can also be a separate bracket for a single differential pressure sensor. When the mounting plate bracket 100 is a separate bracket for the differential pressure sensor, there can be one or more mounting plate brackets 100; this is not specifically limited. Furthermore, the support structure 200 can be a single-piece component or formed from multiple sub-components through welding, assembly, etc.; this is not specifically limited. Additionally, the support mechanism 300 can be in the shape of an "A," an inverted "Y," an inverted "T," etc.; this is not specifically limited. Furthermore, the end of the support mechanism 300 installed on the exhaust manifold of the diesel engine can be angled or not; this is not specifically limited. Furthermore, the mounting crossbar can be angle steel, square or rectangular steel pipe, etc.; this is not specifically limited. Furthermore, the mounting plate bracket 100 can mount one or more differential pressure sensors; this is not specifically limited.

[0030] For ease of description, the embodiments below all use the mounting plate bracket 100 as an integral bracket as an example. For embodiments where the mounting plate bracket 100 is an independent bracket for the differential pressure sensor, please refer to the embodiments below, which will not be repeated here.

[0031] In one embodiment, each support mechanism 300 may include a support rod 310 and a support foot 320. The first end of the support rod 310 is provided with one end for mounting the crossbar 200, and the support foot 320 is obliquely disposed on the support rod 310. The position of the support foot 320 obliquely disposed on the support rod 310 can be varied, such as at the first end of the support rod 310, in the middle of the support rod 310, etc., and is not specifically limited here. Furthermore, there can be one or more support feet 320 disposed on the support rod 310, and is not specifically limited here. Additionally, the angle at which the support foot 320 is obliquely disposed on the support rod 310 can be varied, such as 30°, 40°, 50°, 60°, etc., and is not specifically limited here. Furthermore, the support rod 310 can be a steel pipe such as a square or round shape, or a channel steel, and is not specifically limited here. Furthermore, the support foot 320 can be disposed on the support rod 310 by welding, clamping, or other methods, and is not specifically limited here.

[0032] In one embodiment, the support rod 310 is provided with a groove structure 311, the support foot 320 is obliquely disposed on the support rod 310 through the groove structure 311, and the support rod 310 is provided with a mounting crossbar 200 through the outer side of the groove structure 311.

[0033] In one embodiment, the support rod 310 is provided with a groove structure 311, and the support rod 310 is provided with a crossbar 200 through the groove structure 311. The support foot 320 is provided on the support rod 310 through the outer side of the groove structure 311.

[0034] In one embodiment, a crossbar 200 is installed at the first end of the support rod 310, and an inclined structure 312 is installed at the second end of the support rod 310. The inclination angle of the inclined structure 312 is the same as the angle at which the support foot 320 is inclined on the support rod 310, and the inclined surface of the inclined structure 312 is on the same side as the support foot 320.

[0035] In one embodiment, the mounting crossbar 200 is used to mount the mounting surface of the mounting plate bracket 100, which is parallel to the inclined surface of the inclined structure 312. By making the mounting surface parallel to the inclined surface, the differential pressure sensor mounted on the mounting plate bracket 100 is more stable.

[0036] In one embodiment, the support rod 310 is provided with at least one second mounting hole 313, which can be used to assist in the installation of the flat plate bracket 100. When there is only one second mounting hole 313, it can be located on the side where the first end of the support rod 310 is located, or on the side where the second end of the support rod 310 is located, etc., and is not specifically limited here. Furthermore, when there are multiple second mounting holes 313, their distribution on the support rod 310 is varied; they can be equidistant or unequally spaced, and are not specifically limited here.

[0037] In one embodiment, the support foot 320 is provided with at least one third mounting hole 321, which is aligned with the second mounting hole 313. The third mounting hole 321 can be used to assist in the installation of the plate bracket 100. Since the third mounting hole 321 is aligned with the second mounting hole 313, during the installation of the plate bracket 100 through the second mounting hole 313, the mounting component can simultaneously pass through the second mounting hole 313 and the third mounting hole 321 aligned with the second mounting hole 313. In this way, the plate bracket 100 can be fixed by the entire support structure 300, thereby improving the stability of the plate bracket 100.
