Description

Technical Field

[0001] The present invention belongs to the technical field of ship electrical engineering, and in particular relates to a shock-absorbing protective box for ship electrical equipment. Background Art

[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. Electrical equipment is widely used on ships, but ships often encounter turbulence during navigation. When encountering strong winds, the turbulence will be more severe. Continuous turbulence will affect the operation of the electrical equipment on board, and in severe cases, it will cause damage to the equipment. Therefore, it is necessary to perform shock absorption on the ship's electrical equipment.

[0003] In the Chinese patent publication number CN214579835U, a shock-absorbing device for ship electrical equipment is mentioned. When the ship encounters wind and waves, the electrical equipment body transmits pressure downward through the upper base. At this time, the upper base will squeeze the upper ends of the two connecting rods, causing the lower ends of the two connecting rods to move to the left and right, and drive the two sliders to move to the left and right, so that the sliders squeeze the second spring, and the elasticity of the second spring itself buffers and relieves the pressure. When the ship stabilizes, the elasticity of the second spring itself resets the electrical equipment body; however, the shock absorption method of the shock absorption device is a passive design, and the parameters cannot be dynamically adjusted according to the vibration intensity. When the ship vibration frequency approaches this value, the equipment is prone to resonance, resulting in a sharp increase in the vibration amplitude, which in turn causes damage to the electrical equipment and performance degradation, affecting the shock absorption effect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention uses the coordinated work of the adjustment frame, adjustment chamber, drive mechanism, adjustment plate, adjustment spring and buffer mechanism to sense the vibration intensity and frequency of the ship's electrical equipment in real time through the vibration sensor, and transmits the signal to the controller. The controller commands the drive mechanism according to the vibration conditions, and then changes the compression amount and stiffness of the adjustment spring.

[0021] (2) The present invention achieves a coordinated operation of a fixed frame, shock absorber, guide groove, shock absorber frame and shock absorber spring. The shock absorber first absorbs part of the vibration energy through its own elastic deformation, thereby playing a preliminary buffering role. At the same time, the scissor-type telescopic structure of the shock absorber frame slides in the guide groove, further dispersing and transmitting the vibration energy and avoiding local stress concentration. The shock absorber spring is compressed or stretched according to the magnitude and direction of the vibration, consuming the remaining vibration energy, thereby achieving a multi-stage coordinated operation of shock absorption.

[0022] (3) The present invention uses the coordinated work of a double-headed cylinder, a mounting plate, an adjustment port, an electric telescopic rod and a mounting frame. The double-headed cylinder can simultaneously drive the mounting plates on both sides to move, quickly clamp the electrical equipment, and improve the installation efficiency. The electric telescopic rod can further accurately adjust the position of the mounting frame to ensure that the electrical equipment is firmly installed on the shock-absorbing seat, meeting the installation requirements of equipment of different specifications. This design not only improves the flexibility and accuracy of installation, but also facilitates later maintenance and equipment replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0040] Example 1:

[0041] See also Figures 1 to 8 As shown, a shock-absorbing protective box for marine electrical equipment comprises:

[0042] Equipment protection box 1;

[0043] An adjustment mechanism 2 is installed in the middle of the bottom wall of the equipment protection box 1, and a shock-absorbing seat 3 is installed on the top of the adjustment mechanism 2. A shock-absorbing mechanism 4 is installed between the bottom periphery of the shock-absorbing seat 3 and the bottom wall periphery of the equipment protection box 1. Adjustment slots 5 are opened on the left and right sides of the top of the shock-absorbing seat 3, and a mounting mechanism 6 is installed between the two adjustment slots 5.

[0044] The adjustment mechanism 2 includes an adjustment frame 21, an adjustment cavity 22, a driving mechanism 23, an adjustment plate 24, an adjustment spring 25 and a buffer mechanism 26. The adjustment frame 21 is installed on the bottom box wall of the equipment protection box 1. There are three adjustment cavities 22, three adjustment plates 24 and three adjustment springs 25. The three adjustment cavities 22 are all opened inside the adjustment frame 21. The driving mechanism 23 is installed at the lower part of the adjustment frame 21. The three adjustment plates 24 are all installed at the top of the driving mechanism 23. The three adjustment springs 25 are respectively installed at the top of the three adjustment plates 24. The buffer mechanism 26 is installed between the tops of the three adjustment springs 25.

[0045] Depend on Figures 1 to 5It can be seen that the electrical equipment body 7 is placed on the top of the shock-absorbing seat 3, and vibration sensors 8 are installed on both the front and rear sides of the top of the shock-absorbing seat 3. A sealing cover 9 is installed in the middle of the top wall of the equipment protection box 1 through a hinge. Observation windows 10 are embedded in the middle of the box walls on both sides of the equipment protection box 1. Radiators 11 are embedded in the upper parts of both ends of the equipment protection box 1. A controller 12 is installed at the lower part of one end of the equipment protection box 1.

[0046] The driving mechanism 23 includes a driving rod 231, a driver 232, a worm 233, an adjusting screw 234, a worm gear 235 and a limit block 236. The driving rod 231 is mounted on the lower part of the adjustment frame 21 through a bearing, and the driver 232 is mounted on one end of the driving rod 231. There are three worms 233, three adjusting screws 234, three worm gears 235 and three limit blocks 236. The three worms 233 are mounted on the outer surface of the driving rod 231, and the three adjusting screws 234 are respectively mounted on the bottom walls of the three adjustment chambers 22 through bearings. The three adjusting screws 234 are respectively threadedly connected to the three adjustment plates 24. The three worm gears 235 are respectively mounted on the lower parts of the outer surfaces of the three adjusting screws 234. The three limit blocks 236 are respectively mounted on the top ends of the three adjusting screws 234 through bearings.

[0047] The buffer mechanism 26 includes a buffer frame 261, a limiting cavity 262, a buffer plate 263 and an avoidance hole 264. The buffer frame 261 is inserted and installed at the top of the adjustment frame 21, and the top of the buffer frame 261 is embedded in the bottom end of the shock absorber seat 3. There are three limiting cavities 262, buffer plates 263 and avoidance holes 264. The three limiting cavities 262 are all opened inside the buffer frame 261, and the three buffer plates 263 are all installed at the bottom end of the buffer frame 261, and the bottom ends of the three buffer plates 263 are respectively installed at the top ends of the three adjustment springs 25. The three avoidance holes 264 are respectively opened in the middle of the bottom ends of the three buffer plates 263.

[0048] As can be seen from the above, when the ship vibrates during navigation, the vibration sensor 8 senses the vibration intensity and frequency of the electrical equipment body 7 in real time and transmits the signal to the controller 12. After analyzing and processing the vibration signal, the controller 12 sends a control instruction to the driver 232 in the drive mechanism 23. The driver 232 drives the drive rod 231 to rotate, and the three worms 233 on the drive rod 231 rotate synchronously. Since the three worms 233 are respectively engaged with the corresponding worm gears 235 for transmission, the rotation of the worm gear 235 drives the three adjustment screws 234 to rotate in the adjustment cavity 22. The three adjustment screws 234 drive the three adjustment plates 24 to move up and down through the threaded connection, thereby changing the installation The compression amount of the three adjustment springs 25 at the top of the adjustment plate 24 realizes the dynamic adjustment of the spring stiffness. This dynamic adjustment mechanism enables the protective box to automatically adapt to different vibration conditions: when it is detected that the ship encounters a large amplitude turbulence, the controller 12 increases the compression amount of the adjustment spring 25 through the driving mechanism 23, enhances the spring stiffness, and prevents the electrical equipment body 7 from being damaged by collision due to severe vibration; when the amplitude is small, the compression amount is reduced to reduce the stiffness, reduce energy loss, and improve the shock absorption efficiency. This adjustment capability covering all working conditions significantly improves the stability and reliability of ship electrical equipment in complex sea conditions, reduces the equipment failure rate, and extends the equipment service life.

[0049] Specifically, refer to Figures 1 to 5 As shown, the buffer frame 261 is set to an E-type structure, the diameter of the avoidance hole 264 is larger than the diameter of the adjustment screw 234, the driver 232 and the vibration sensor 8 are both electrically connected to the controller 12, the worm 233 is engaged with the corresponding worm gear 235, the limit block 236 is located inside the limit cavity 262, and the adjustment frame 21 is set to a W-shaped structure.

[0050] As can be seen from the above, the E-type structure has specific mechanical properties and spatial layout advantages, which helps the buffer frame 261 to disperse and absorb vibration energy, provide more stable support, and ensure that the adjustment screw 234 will not interfere with the avoidance hole 264 during movement. The vibration sensor 8 is used to monitor the vibration of the ship's electrical equipment in real time, and convert the vibration signal into an electrical signal and transmit it to the controller 12. The controller 12 analyzes and processes the received vibration signal, and then sends a control instruction to the driver 232, and transmits power to the adjustment screw 234 through meshing transmission, so that the limit block 236 can move flexibly inside the limit cavity 262. The adjustment frame 21 with a W-shaped structure has high strength and stability and can withstand large loads.

[0051] Example 2:

[0052] refer to Figure 6 and Figure 7As shown, the shock absorbing mechanism 4 includes a fixed frame 41, a shock absorber 42, a guide groove 43, a shock absorbing frame 44 and a shock absorbing spring 45. Two fixed frames 41 are provided, and the two fixed frames 41 are respectively installed on the bottom box wall of the equipment protection box 1 and the bottom end of the shock absorbing seat 3. Four shock absorbers 42 and four guide grooves 43 are provided. The four shock absorbers 42 are installed at the four corners of the opposite surfaces of the two fixed frames 41. The four guide grooves 43 are respectively opened in the middle of the inner walls on both sides of the two fixed frames 41. The shock absorbing frame 44 is slidably installed inside the four guide grooves 43. A plurality of shock absorbing springs 45 are provided, and the plurality of shock absorbing springs 45 are respectively installed on the other two inner walls of the two fixed frames 41.

[0053] The shock-absorbing frame 44 includes a movable frame body 441, a guide rod 442 and a shock-absorbing bar 443. There are two movable frames 441, and there are four guide rods 442 and four shock-absorbing bars 443. The four guide rods 442 are respectively installed at the four corners of the opposite surfaces of the two movable frames 441 through bearings, and the four shock-absorbing bars 443 are respectively installed in the middle of the outer surfaces of the four guide rods 442.

[0054] As can be seen from the above, when the ship vibrates, the shock-absorbing seat 3 undergoes relative displacement inside the equipment protection box 1. First, the four shock absorbers 42 installed at the four corners of the opposite surfaces of the two fixed frames 41 perform preliminary buffering, and absorb part of the vibration energy through their own elastic deformation. At the same time, the shock-absorbing frame 44 slidingly installed in the four guide grooves 43 starts to work: when the vibration is transmitted to the shock-absorbing frame 44, the four guide rods 442 drive the four shock-absorbing bars 443 to slide in the guide grooves 43, and the movable frame 441 of the scissor-type telescopic structure is deformed by the sliding of the guide rods 442, converting the longitudinal vibration into lateral movement, thereby dispersing the vibration energy and avoiding local stress concentration. At this time, the multiple shock-absorbing springs 45 installed on the inner walls on the other two sides of the two fixed frames 41 further absorb and disperse the remaining vibration energy through elastic deformation, realizing multi-stage shock absorption coordinated work. This design effectively isolates the direct impact of ship vibration on electrical equipment, significantly reduces the stress damage to the equipment caused by vibration, and ensures the stability and reliability of equipment performance. It is especially suitable for high-frequency and large-amplitude harsh sea conditions.

[0055] Preferably, reference Figure 6 and Figure 7 As shown, the movable frame 441 is configured as a scissor-type telescopic structure, the guide rod 442 is slidably connected to the corresponding two guide grooves 43, and the fixed frame 41 is configured as a rectangular frame.

[0056] As can be seen from the above, the scissor-type telescopic structure has good telescopic performance and stability, so that the movable frame 441 can adapt to the different position changes of the shock-absorbing seat 3 through telescopic movement, and at the same time can effectively disperse and transmit vibration energy. The guide groove 43 guides and positions the guide rod 442, and the reasonable layout of the rectangular frame is conducive to the transmission and dispersion of force.

[0057] Example 3:

[0058] refer to Figure 8 As shown, the mounting mechanism 6 includes a double-headed cylinder 61, a mounting plate 62, an adjustment port 63, an electric telescopic rod 64 and a mounting bracket 65. The double-headed cylinder 61 is embedded between the inner walls of the two adjustment slots 5. Two mounting plates 62, two adjustment ports 63, electric telescopic rods 64 and two mounting brackets 65 are provided. The two mounting plates 62 are respectively mounted on the two output ends of the double-headed cylinder 61. The two adjustment ports 63 are respectively opened on the upper part of the opposite surfaces of the two mounting plates 62. The two electric telescopic rods 64 are respectively embedded in the middle of the bottom inner wall of the two adjustment ports 63. The two mounting brackets 65 are respectively installed with the output ends of the two electric telescopic rods 64.

[0059] As can be seen from the above, when the electrical equipment body 7 needs to be installed inside the equipment protection box 1, first open the sealing cover 9 and place the electrical equipment body 7 on the shock-absorbing seat 3. The controller 12 controls the double-headed cylinder 61 to start, and its two output ends synchronously drive the two mounting plates 62 to move toward the middle along the adjustment slot 5, and clamp and install from the left and right directions to adapt to the width of electrical equipment of different specifications. After the electric telescopic rod 64 is started, it drives the mounting frame 65 to move vertically, and clamp and install from the top and bottom directions to adapt to the height of electrical equipment of different specifications. The two work together to achieve efficient and accurate installation to meet the installation requirements of equipment of different sizes. This design not only improves the flexibility and accuracy of installation, but also facilitates later maintenance and equipment replacement. At the same time, the I-shaped mounting frame 65 enhances the stability of equipment installation, reduces additional vibration and stress concentration caused by improper installation, and further ensures the long-term stable operation of electrical equipment in the ship environment.

[0060] Preferably, reference Figure 8 As shown, the double-headed cylinder 61 and the electric telescopic rod 64 are both electrically connected to the controller 12, the lower portion of the outer surface of the mounting plate 62 is provided with a protrusion matching the inner wall of the adjustment slot 5, and the mounting frame 65 is provided as an I-shaped structure.

[0061] As can be seen from the above, the controller 12 can send control signals to the double-headed cylinder 61 and the electric telescopic rod 64. The design of the protrusion matching the inner wall of the adjustment groove 5 can enable the mounting plate 62 to slide stably in the adjustment groove 5, playing a guiding and positioning role. The I-shaped mounting bracket 65 can be limited in the adjustment port 63 to improve stability.

[0062] Application examples:

[0063] This design is applied to the navigation and operation scenarios of ships in various complex environments, covering normal navigation in calm offshore waters, severe sea conditions encountered in the open ocean with strong winds and waves, and operations such as berthing and leaving ports and loading and unloading of cargo. During normal navigation, the protective box can play an important role in the face of low-frequency and small turbulence caused by slight fluctuations of waves, or instantaneous impact vibrations caused by cargo movement and lifting equipment operation in port operations, as well as high-frequency and large-scale violent turbulence and shaking when sailing in the ocean and encountering typhoons and cyclones. Its working principle is that the vibration sensor 8 senses the vibration intensity and frequency of the electrical equipment body 7 in real time and transmits the signal to the controller 12. The controller 12 directs the drive mechanism 23 accordingly, and uses the worm 233 to The transmission change with the worm gear 235 adjusts the stiffness of the spring 25 to achieve dynamic parameter adjustment, enhancing the stiffness to prevent collision when the amplitude is large, and reducing the stiffness to reduce energy consumption when the amplitude is small; the scissor-type telescopic structure of the shock absorber 42 and the shock-absorbing frame 44 in the shock-absorbing mechanism 4 cooperates with the shock-absorbing spring 45 in multiple stages to absorb and disperse vibration energy; the installation mechanism 6 uses the double-headed cylinder 61 and the electric telescopic rod 64 to flexibly install and adjust the electrical equipment body 7. In actual application, it effectively reduces the impact of ship vibration on electrical equipment, improves equipment reliability and service life, ensures stable equipment performance, enhances equipment adaptability to different environments, and also reduces equipment maintenance frequency and manual maintenance workload, thereby reducing the overall cost of ship operation.
