Description

Technical Field

[0001] This utility model relates to the field of diesel engine technology, and in particular to a protective cover bracket for a marine engine shaft temperature sensor. Background Technology

[0002] In the stable operation of a ship's power system, the marine shaft temperature sensor plays an indispensable role as a key device for detecting the operating status of the shafting system. It can monitor the temperature of the shafting system in real time and provide important data support for the safe navigation of the ship. Once a malfunction occurs, it will seriously affect the normal operation of the ship and may even cause a major safety accident.

[0003] However, the operating environment of ships is extremely complex. Continuous vibration, frequent impacts, and leakage of various liquids pose a great threat to the normal operation of shaft temperature and wear sensors. Traditional shaft temperature sensors are often directly connected to the diesel engine with bolts or installed with simple brackets. This method lacks a specific design for the special operating environment of ships and is difficult to effectively resist the effects of adverse factors such as vibration and impact. During long-term operation, the sensors are easily damaged by impacts, which not only shortens the service life of the sensors and increases maintenance costs, but also poses a risk of failure in monitoring the shaft system's operating status due to sensor failure, thus creating hidden dangers for the safe navigation of ships.

[0004] Therefore, it is necessary to provide a new protective cover bracket for marine engine shaft temperature sensors to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a protective cover bracket for a marine engine shaft temperature sensor.

[0006] The protective cover bracket for a marine engine shaft temperature sensor provided by this utility model includes: a protective cover bracket, fixed to the diesel engine base body, made of high-strength corrosion-resistant material, a mounting plate fixedly connected to the top of the protective cover bracket, a rotating plate rotatably connected to one side of the mounting plate, a wire harness assembly installed at the bottom of the rotating plate, and a limit component installed at the connection between the mounting plate and the rotating plate.

[0007] Preferably, the protective cover bracket consists of a bent plate and a cover plate. The surface of the bent plate has multiple sets of circular through holes symmetrically opened. The protective cover bracket can be connected to the base and sensor by bolts fitting into the circular holes.

[0008] Preferably, the cover plate is located above the bent plate, and the protective cover bracket has a semi-enclosed structure, with the cover plate providing protection only above the sensor, while the space on the sides and below the sensor is reserved for sensor wiring.

[0009] Preferably, the cable harness assembly includes: a cable harness ring, a cable harness strip, a locking tooth, a tooth groove, a first spring, a connecting post, and a knob. The cable harness ring is fixedly connected to the bottom of the rotating plate. The cable harness strip is fixedly connected to one end of the cable harness ring. The locking tooth is slidably connected to the other end of the cable harness ring. One end of the cable harness strip is inserted into the cable harness ring near the locking block. Multiple sets of tooth grooves are equidistantly formed on the outer wall of the cable harness strip. The locking tooth engages with the tooth groove. The first spring is fixedly connected to the end of the locking tooth away from the tooth groove. One end of the first spring is fixedly connected to the cable harness strip. The connecting post is rotatably connected to one end of the locking tooth. One end of the connecting post extends out of the cable harness ring and is fixedly connected to a knob.

[0010] Preferably, the limiting component includes: a square post, a second spring, a square groove, a push block, and a push rod. The square post is slidably connected inside the mounting plate. The end of the square post away from the rotating plate is fixedly connected to the second spring, which is fixedly connected to the inner wall of the mounting plate. A square groove is opened on the top of the rotating plate, and the square post is inserted into the square groove. The push block is slidably connected inside the rotating plate. One end of the push block contacts the square post, and the other end of the push block is fixedly connected to the push rod.

[0011] Preferably, the knob has a beveled design on the side near the connecting post, and the outer wall of the knob has anti-slip texture.

[0012] Preferably, the top surface of the locking teeth is a flat surface, and the bottom surface of the locking teeth is a beveled surface.

[0013] Preferably, the diameter of the push block is equal to the side length of the square column, and the diameter of the push rod is smaller than the diameter of the push block.

[0014] Compared with related technologies, the protective cover bracket for marine engine shaft temperature sensors provided by this utility model has the following advantages:

[0015] Fixed and stable:

[0016] The protective cover bracket achieves a dual bolt connection with the shaft temperature sensor and the diesel engine body through multiple sets of circular through holes on the bent plate. Compared with the traditional single bolt connection or simple bracket-assisted installation, this design greatly enhances the connection stability between the bracket and the sensor and diesel engine. Even if the ship experiences severe vibrations in complex sea conditions, the protective cover bracket can ensure that the shaft temperature sensor remains firmly installed, effectively preventing loosening of the connection or displacement of the sensor due to vibration, and providing a reliable hardware foundation for shaft temperature monitoring.

[0017] Good protective effect:

[0018] The protective cover bracket adopts a semi-enclosed structure. The upper cover plate can reduce the risk of impact and leakage from above, providing targeted protection for the sensor. Compared with the lack of effective protection for sensors under traditional installation methods, this bracket can significantly reduce the probability of damage to the sensor by external factors, extend the service life of the sensor, reduce maintenance costs and downtime caused by sensor damage, and ensure the continuity and stability of ship power system monitoring.

[0019] Easy to use:

[0020] The ingenious combination of the rotating plate and the limiting component gives the bracket convenient operability. When the sensor needs maintenance, repair, or adjustment, the operator only needs to press the push rod to release the limit and easily rotate the rotating plate to the required angle. After releasing the push rod, the limiting component automatically resets and precisely fixes the rotating plate. Without the need for complicated tools, the operation process is greatly simplified and the maintenance efficiency is significantly improved. The innovative design of the wire harness component is equally outstanding. The wire harness tape, clamping teeth, and grooves work together to achieve quick tightening and loosening of the wires. This orderly wire management method effectively avoids loose and tangled wires and friction damage. It not only improves the safety of the line, but also facilitates quick positioning and handling of wires during maintenance, further optimizing the maintenance convenience of the ship shaft temperature monitoring system.

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 5 A protective cover bracket 1 for a marine engine shaft temperature sensor is disclosed. The protective cover bracket 1 includes: a protective cover bracket 1 fixed to the diesel engine base body, made of high-strength corrosion-resistant material; a mounting plate 2 fixedly connected to the top of the protective cover bracket 1; a rotating plate 3 rotatably connected to one side of the mounting plate 2; a wiring assembly installed at the bottom of the rotating plate 3; a limit assembly installed at the connection between the mounting plate 2 and the rotating plate 3; the protective cover bracket 1 is composed of a bent plate 4 and a cover plate 5; multiple sets of circular through holes are symmetrically opened on the surface of the bent plate 4; the protective cover bracket 1 can be connected to the engine base and the sensor by bolts and the circular holes; the cover plate 5 is located above the bent plate 4; the protective cover bracket 1 has a semi-enclosed structure, with the cover plate 5 providing protection only above the sensor, and the space on the side and below the sensor reserved for sensor wiring.

[0030] It should be noted that the cover plate 5 only provides protection above the sensor, while the space on the sides and below the sensor is reserved for the sensor wiring. This design can reduce the risk of damage to the sensor caused by impacts from above and drips, while ensuring that the sensor has sufficient space for wiring operations.

[0031] Please see Figure 1 and Figure 5 The cable harness assembly includes: a cable harness ring 6, a cable harness strip 7, a locking tooth 8, a tooth groove 9, a first spring 10, a connecting post 11, and a knob 12. The bottom of the rotating plate 3 is fixedly connected to the cable harness ring 6. One end of the cable harness ring 6 is fixedly connected to the cable harness strip 7. The other end of the cable harness ring 6 is slidably connected to the locking tooth 8. One end of the cable harness strip 7 is inserted into the end of the cable harness ring 6 near the locking block. Multiple sets of tooth grooves 9 are equidistantly opened on the outer wall of the cable harness strip 7. The locking tooth 8 is inserted into the tooth groove 9. The end of the locking tooth 8 away from the tooth groove is fixedly connected to the first spring 10. One end of the first spring 10 is fixedly connected to the cable harness strip 7. One end of the locking tooth 8 is rotatably connected to the connecting post 11. One end of the connecting post 11 extends out of the cable harness ring 6 and is fixedly connected to the knob 12. The side of the knob 12 near the connecting post 11 is designed with a bevel. The outer wall of the knob 12 is provided with anti-slip texture. The top surface of the locking tooth 8 is flat, and the bottom surface of the locking tooth 8 is beveled.

[0032] It should be noted that the tooth 8 engages with the slot through the top flat surface, and the bevel of the tooth 8 facilitates the upward lifting of the cable tie 7. This lifting process can be completed without operating the knob 12.

[0033] Please see Figure 1 and Figure 5 The limiting assembly includes: a square post 13, a second spring 14, a square groove 15, a push block 16, and a push rod 17. The square post 13 is slidably connected inside the mounting plate 2. The second spring 14 is fixedly connected to the end of the square post 13 away from the rotating plate 3. The second spring 14 is fixedly connected to the inner wall of the mounting plate 2. The top of the rotating plate 3 has a square groove 15, into which the square post is inserted. The push block 16 is slidably connected inside the rotating plate 3. One end of the push block 16 contacts the square post, and the other end of the push block 16 is fixedly connected to the push rod 17. The diameter of the push block 16 is equal to the side length of the square post 13, and the diameter of the push rod 17 is smaller than the diameter of the push block 16.

[0034] It should be noted that the snap-fit ​​between the square block and the square slot 15 enables the square block to limit the rotation plate 3. At the same time, the design of the square block and the square slot 15 allows the rotation plate 3 to be limited by inserting the square block into the square slot 15 every 90° rotation.

[0035] The working principle of the protective cover bracket 1 for marine engine shaft temperature sensor provided by this utility model is as follows:

[0036] Install protective cover bracket 1:

[0037] The protective cover bracket 1 is made of high-strength corrosion-resistant material. Its unique structural design makes it easy and stable to install. The protective cover bracket 1 consists of a bent plate 4 and a cover plate 5. Multiple sets of circular through holes are symmetrically opened on the surface of the bent plate 4. These through holes are the key structure for installation and fixation. During installation, the four through holes on the protective cover bracket 1 are aligned coaxially with the corresponding holes of the shaft temperature sensor. The protective cover bracket 1 and the shaft temperature sensor are fastened together by bolts passing through the through holes, thus achieving the initial fixation of the two. Then, the four through holes behind the bent plate 4 of the protective cover bracket 1 are connected to the corresponding mounting holes on the diesel engine body by bolts. This double bolt connection method can ensure that the protective cover bracket 1 is firmly fixed on the diesel engine base body, providing a stable installation foundation for the shaft temperature sensor.

[0038] The cover plate 5 above the protective cover bracket 1 provides effective protection for the sensor during the operation of the ship's engine. Due to its semi-enclosed structure design, the cover plate 5 only provides protection above the sensor, while the space on the sides and below the sensor is reserved for sensor wiring. This design can reduce the risk of damage to the sensor caused by impacts and drips from above, while ensuring that the sensor has sufficient space for wiring operations. At the same time, when the sensor fails, the sensor can be easily replaced by simply removing the connecting bolts, which greatly improves the convenience and efficiency of maintenance.

[0039] Rotate plate 3:

[0040] The rotation of the rotating plate 3 is precisely controlled by a limiting assembly, which mainly consists of a square post 13, a second spring 14, a square groove 15, a push block 16, and a push rod 17. When the rotating plate 3 needs to be rotated, the operator presses the push rod 17. Under pressure, the push rod 17 pushes the push block 16 to slide inside the rotating plate 3. During the movement of the push block 16, it squeezes the square post 13, which is slidably connected to the mounting plate 2, causing the square post 13 to overcome the elastic force of the second spring 14 and disengage from the square groove 15 at the top of the rotating plate 3. Simultaneously, the second spring 14 is compressed. At this point, since the square post 13 no longer limits the rotation of the rotating plate 3, the rotating plate 3 can... After the rotating plate 3 is rotated 90° to the desired position, the push rod 17 is released. At this time, the second spring 14 loses the external force and begins to reset. Its elastic potential energy is converted into kinetic energy, which pushes the square column 13 to re-insert into the square groove 15 at the top of the rotating plate 3. The square column 13 limits the rotating plate 3 through the square groove 15, fixing it in a new position. At the same time, the movement of the square column 13 will also push the push block 16 and the push rod 17 to reset, completing the rotation and fixing operation of the rotating plate 3. This limiting component design ensures that the rotating plate 3 can rotate flexibly when needed, while remaining stable in a fixed position, meeting the needs of different operating scenarios.

[0041] Wire harness operation:

[0042] The cable bundling assembly mainly consists of a cable bundling ring 6, a cable bundling tape 7, locking teeth 8, toothed grooves 9, a first spring 10, a connecting post 11, and a knob 12. Its working principle is based on a clever mechanical structure to effectively bind the wires. During the bundling operation, the cable bundling tape 7 is first passed under the wire, then inserted into the end of the cable bundling ring 6 with the locking teeth 8. Next, the cable bundling tape 7 is pulled upwards. As the cable bundling tape 7 is pulled upwards, it gradually contracts, tightly binding the wires together. In this process, the multiple sets of toothed grooves 9 evenly spaced on the outer wall of the cable bundling tape 7 play a crucial role. When the cable bundling tape 7 is pulled, the toothed grooves 9 continuously compress the locking teeth 8. The tooth 8 overcomes the elastic force of the first spring 10, compresses the first spring 10, and moves away from the cable tie 7. As the cable tie 7 is pulled up further, when the appropriate tooth groove 9 aligns with the tooth 8, the elastic potential energy of the first spring 10 is released, pushing the tooth 8 into the tooth groove 9 to form a snap-fit, thereby fixing the cable tie 7 and firmly binding the wires together. This cable binding method is simple to operate, can be flexibly adjusted according to the number and thickness of the wires, and the snap-fit ​​structure is stable and reliable, ensuring that the wires will not loosen during the operation of the ship's engine, effectively protecting the wires and avoiding safety hazards caused by loose wires.

[0043] Remove the harness:

[0044] When it is necessary to untie the cable bundle, the operator can do so by rotating the knob 12. The side of the knob 12 near the connecting post 11 is designed with an angled surface and has anti-slip texture on the outer wall for easy operation. When the knob 12 is rotated 90°, due to its angled design, the knob 12 will move away from the cable bundle ring 6 along the angled direction, and at the same time drive the connecting post 11 to move synchronously. The movement of the connecting post 11 will drive the locking teeth 8 connected to it to move synchronously, so that the locking teeth 8 disengage from the locking groove on the outer wall of the cable bundle 7, thereby releasing the restriction on the cable bundle 7. At this time, the cable bundle 7 is no longer restrained by the locking teeth 8 and can be easily pulled down to complete the untying operation. This method of untying the cable bundle is ingeniously designed, simple and quick to operate, and can quickly untie the cable bundle when it is necessary to adjust, repair or replace the wires, thus improving work efficiency.
