Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to an engine speed sensor mounting bracket. Background Technology

[0002] In the field of marine navigation, engine speed sensors play a crucial role. Their primary function is to monitor the real-time speed of marine engines, providing precise data support for multiple critical ship systems. Specifically, based on the speed information fed back by the speed sensor, the main engine control system can precisely regulate key parameters such as fuel injection and air intake, ensuring the engine operates at a consistently high efficiency, stability, and economy. Simultaneously, in terms of ship safety monitoring, the safety monitoring system closely monitors engine speed in real time. If abnormal fluctuations in speed are detected, or if the speed exceeds the preset normal range, the system will immediately issue an alarm signal. If the speed continues to rise abnormally, the main engine will automatically shut down, effectively protecting the life and property of the ship and its crew. Therefore, the engine speed sensor is an indispensable core component for the normal navigation and safe operation of a ship.

[0003] In ship main engine construction, traditional engine speed sensor mounting brackets are often placed in confined spaces with dense piping. They typically need to be anchored to the main engine mount and then assembled from multiple components to secure the sensor. However, this structure often leads to interference with piping due to the complex installation space, and the bracket itself vibrates significantly, resulting in poor stability of the monitoring data and making the installation process extremely inconvenient.

[0004] Traditional speed sensor mounting brackets present several problems. Firstly, they require anchoring to the main engine mount and are assembled from multiple components, resulting in complex welding processes with extremely high precision requirements. Even slight deviations can lead to unstable connections between the bracket and the engine, affecting sensor accuracy. In the complex construction environment of ships, the assembly of multiple components can also lead to error accumulation, further increasing installation difficulty and reducing efficiency. Secondly, their structure cannot effectively buffer vibrations generated by the engine during ship navigation. These vibrations are directly transmitted to the sensor, damaging its internal precision components, shortening its lifespan, and potentially causing loose connections between the sensor and the bracket, affecting the stability and reliability of monitoring data. Furthermore, traditional brackets lack adjustability, failing to adapt flexibly to actual installation needs. Once installed, the sensor position is essentially fixed, making it difficult to accommodate different engine models, installation locations, and variations in ship construction processes. This increases the risk of installation errors and reduces installation flexibility and adaptability. Utility Model Content

[0005] This utility model provides an engine speed sensor mounting bracket, which solves the problem that the position and angle of existing sensor mounting brackets cannot be adjusted.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An engine speed sensor mounting bracket includes a vertical fixing plate and a horizontal fixing plate that are perpendicular to each other, wherein the bottom of the vertical fixing plate is connected to the side of the horizontal fixing plate;

[0008] The vertical fixing plate is provided with fixing holes and moving holes. The fixing holes are circular. With the end closest to the horizontal fixing plate as the bottom, the moving hole is an arc shape with the center pointing downwards. The fixing hole is located at the center of the arc shape of the moving hole and is located below the moving hole. The fixing holes and moving holes are fixed to the angle encoder probe bracket by bolts.

[0009] The horizontal fixed plate is provided with sensor mounting holes, and an engine speed sensor is installed in the sensor mounting holes; the engine speed sensor is located on the outside of the engine flywheel.

[0010] Furthermore, the vertical fixing plate and the horizontal fixing plate are an integrated structure.

[0011] Furthermore, the width of the vertical fixing plate is equal to the width of the horizontal fixing plate.

[0012] Furthermore, a gasket is provided between the bolt and the fixing hole and the moving hole.

[0013] Furthermore, from the direction closest to the flywheel to the direction furthest from the flywheel, the horizontal fixing plate, fixing hole, and moving hole are arranged in sequence.

[0014] Furthermore, the main body of the sensor mounting hole is an elongated strip structure, and both ends of the sensor mounting hole are arc-shaped structures.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model uses a design with a fixed hole on a vertical fixed plate and a downward-pointing arc-shaped movable hole, combined with bolt connection. By adjusting the bracket angle, the gap between the speed sensor and the flywheel can be precisely adjusted to the design requirements, effectively improving installation flexibility and adaptability.

[0017] This utility model adopts an integrated structure in which the vertical fixing plate and the horizontal fixing plate are perpendicular to each other, combined with the buffer design of the arc-shaped moving hole, which can reduce the vibration of the bracket, improve the stability of the sensor monitoring data, and effectively solve the problem of excessive vibration of traditional brackets.

[0018] This utility model features a compact overall structure and small size, requiring minimal installation space. It is particularly suitable for small machines in confined spaces, especially in environments equipped with shaft-driven generators, effectively avoiding interference with pipelines. The optimized structural design simplifies the installation process, making installation convenient, reducing the skill and time requirements for installers, and improving assembly efficiency.

[0019] The elongated sensor mounting hole and the rounded ends on the horizontal fixing plate of this utility model facilitate the adjustment of the sensor position, adapt to different engine models, and have greater versatility. Attached Figure Description

[0031] This utility model provides a technical solution: an engine speed sensor mounting bracket, such as... Figure 1 and 2 As shown, it includes a vertical fixing plate 1 and a horizontal fixing plate 2 that are perpendicular to each other. The bottom of the vertical fixing plate 1 is connected to the side of the horizontal fixing plate 2; the vertical fixing plate 1 and the horizontal fixing plate 2 are an integrated structure. The width of the vertical fixing plate 1 is equal to the width of the horizontal fixing plate 2.

[0032] The vertical fixing plate 1 is provided with a fixing hole 3 and a moving hole 4. The fixing hole 3 is circular. Taking the end closest to the horizontal fixing plate 2 as the bottom, the moving hole 4 is an arc shape with the center pointing downwards.

Once the appropriate angle is achieved, bolts are passed through the mounting and movable holes to secure the vertical mounting plate to the angle encoder probe bracket. Shims further enhance the tightness and stability of the connection. Simultaneously, the elongated structure and arc-shaped ends of the sensor mounting hole facilitate adjustment of the engine speed sensor's position on the horizontal mounting plate, ensuring better alignment with the engine flywheel and adapting to the installation requirements of different engine models and locations.
