Description

Technical Field

[0001] The utility model relates to the technical field of an anti-falling protection device for an electrical box, in particular to an anti-falling protection device for an electrical box of an electronically controlled diesel engine for a ship. Background Art

[0002] With the continuous updating and development of marine diesel engine technology, intelligent electronically controlled diesel engines have become the mainstream trend of development. Some conventional mechanical transmission components are gradually replaced by electrical control components, and the highly integrated characteristics of the electronic control components themselves have led to the increasingly centralized layout of the electrical control boxes on the electronically controlled diesel engines, and the weight and size of the electrical boxes have become increasingly large. At the same time, due to the limitations of the diesel engine's own size and the installation space on board, the electrical boxes currently designed are all wall-mounted. The electrical box is fixed on a bracket welded by channel steel, and the bracket is hung on the supporting columns of the two-layer platform of the diesel engine. On the other hand, due to the large number of equipment on board, the main engine, auxiliary engine and other power equipment in the engine room vibrate relatively greatly during operation on board, which makes the working environment of the electrical control box on the diesel engine relatively harsh, which in turn leads to the risk of accidental falling of the electrical control box on the electronically controlled diesel engine during the long-term operation of the diesel engine, causing physical damage to the crew working near the electrical box on board, and also breaking the wiring cable of the electrical control box, affecting the safe operation of the electronically controlled diesel engine.

[0003] Therefore, there is an urgent need for a marine electronically controlled diesel engine electrical box anti-fall protection device. Utility Model Content

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a technical solution. Please refer to Figure 1 and Figure 2 , a shipboard electric control diesel engine electric box anti-falling protection device, comprising: an electric box installation column 1, a channel steel bracket 2 and a stop pad 3, and the channel steel bracket 2 is connected to the electric box installation column 1 through a pipe clamp. The electric box installation column 1 and the channel steel bracket 2 can be connected to the electric box. A channel steel is assembled outside the channel steel bracket 2, and a spring nut 4 is assembled outside the channel steel. A guide bolt 5 is connected inside the spring nut 4, and a lock washer 6 is assembled between the guide bolt 5 and the spring nut 4. A counterbore is provided at the top of the stop pad 3, and the counterbore is aligned with the axes of the spring nut 4 and the guide bolt 5. The guide bolt 5 and the stop pad 3 cooperate to prevent the electric box from falling, and the lock washer 6 can increase the connection stability between the guide bolt 5 and the spring nut 4.

[0024] Please refer to Figure 3 and Figure 4, an alarm mechanism 7 is assembled inside the stop pad 3. The spring nut 4 includes a nut, a spring is assembled at the bottom of the nut, and the spring is welded to the nut. The spring can buffer the nut after movement, and a damping rod can be assembled between the spring and the nut to enhance the buffering effect. The spring at the bottom of the spring nut 4 is assembled inside the stop pad 3 through a bolt. The spring nut 4 makes elastic contact through the spring, which plays a role in positioning the electrical box during the assembly process and reduces the vibration of the electrical box during the operation of the diesel engine.

[0025] The alarm mechanism 7 includes a horn 71 and a battery pack 73. Wires 72 are assembled between the horn 71 and the battery pack 73 and on the right side of the horn 71. A spring plate group 74 is assembled on the right side of the battery pack 73. The horn 71 can sound when powered on. The wire 72 cooperates with the spring plate group 74 to transfer the current of the battery pack 73 to the horn 71. The horn 71 and the battery pack 73 are common alarm devices and batteries in the prior art, and the battery can supply energy to the alarm device.

[0026] The spring plate group 74 includes an elastic plate. A copper plate is embedded at the bottom of the elastic plate, and the copper plate is connected to the battery pack 73. The elastic plate is made of plastic to prevent conduction when the guide bolt 5 contacts the spring plate group 74. The electrical box mounting column 1, the stop pad 3, the spring nut 4, the guide bolt 5, the lock washer 6, and the alarm mechanism 7 are all in two groups, which are respectively assembled on both sides of the electrical box. The stability of fixing the electrical box can be increased through the setting of the two groups.

[0027] During the installation of this solution, by calculating the installation position of the channel steel bracket 2 of the electrical box in advance, the stop pad 3 is welded at the corresponding position of the electrical box mounting column 1 in advance. Before hoisting the electrical box, the spring nut 4 is installed on the channel steel bracket 2 first. When hoisting the electrical box assembly including the electrical box and the mounting bracket, adjust the position of the electrical box so that the springs below each spring nut 4 are aligned with the counterbored holes of the stop pad 3, and then lower the electrical box assembly.

[0028] At this time, the channel steel bracket 2 and the stop pad 3 make elastic contact through the spring, which plays a role in positioning the electrical box during the assembly process; at the same time, it reduces the vibration of the electrical box during the operation of the diesel engine;

[0029] Even if the bolts of the electrical box become loose and the electrical box falls due to long-term operation, the spring nut 4 will reduce the impact of the electrical box falling; in addition, once the electrical box falls, the guide bolt 5 will enter the through hole of the stop pad 3, which can fix the electrical box to prevent it from tipping over;

[0030] When the guide bolt 5 is inserted into the inside of the stop pad 3, it will push the spring plate group 74 to descend, and then be energized with the battery pack 73, so that the horn 71 is energized to produce a sound, warning that the assembly position of the electrical box is loose.
