Abstract
Description
Technical Field
[0001] This invention relates to the technical field of electrical box anti-fall protection devices, specifically an anti-fall protection device for a marine electronic control diesel engine electrical box. Background Technology
[0002] With the continuous updating and development of marine diesel engine technology, intelligent electronically controlled diesel engines have become the mainstream trend. Some conventional mechanical transmission components are gradually being replaced by electrical control components. The highly integrated nature of these components leads to increasingly concentrated placement of electrical control boxes on electronically controlled diesel engines, resulting in larger and heavier boxes. Furthermore, due to the size of the diesel engine itself and the limitations of onboard installation space, current electrical boxes are wall-mounted. The boxes are fixed to a bracket welded from channel steel, which is then suspended from the support columns of the diesel engine's two-tiered platform. On the other hand, due to the numerous pieces of equipment on board, the main engine, auxiliary engines, and other power equipment experience relatively high vibrations during operation. This creates a harsh working environment for the electrical control boxes on the diesel engine, potentially leading to the risk of accidental falls during prolonged engine operation. This could cause injury to crew members working near the boxes, break the wiring cables, and affect the safe operation of the electronically controlled diesel engine.
[0003] Therefore, there is an urgent need for a fall protection device for the electrical box of a marine electronically controlled diesel engine. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a fall protection device for the electrical box of a marine electronically controlled diesel engine, thereby solving the aforementioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the present invention provides the following technical solution: a fall protection device for an electrical box of a marine electronically controlled diesel engine, comprising: an electrical box mounting column, a channel steel bracket, and a stop block, wherein the channel steel bracket is connected to the electrical box mounting column via a pipe clamp, the channel steel bracket is externally fitted with a channel steel, and a spring nut is externally fitted with the channel steel, a guide bolt is internally connected to the spring nut, a locking washer is fitted between the guide bolt and the spring nut, the top of the stop block is provided with a countersunk hole, and the countersunk hole is aligned with the axis of the spring nut and the guide bolt, and an alarm mechanism is internally fitted with the stop block.
[0008] Preferably, the spring nut includes a nut, a spring is fitted at the bottom of the nut, and the spring is welded to the nut. The spring can dampen the nut after movement, and a damping rod can be fitted between the spring and the nut to increase the damping effect.
[0009] Preferably, the spring at the bottom of the spring nut is bolted to the inside of the stop pad, and the spring nut makes elastic contact with the spring, which plays a role in positioning the electrical box during assembly and at the same time reduces the vibration of the electrical box during the operation of the diesel engine.
[0010] Preferably, the alarm mechanism includes a horn and a battery pack. Wiring is installed between the horn and the battery pack and on the right side of the horn. A spring clip assembly is installed on the right side of the battery pack. The horn can be powered on to sound, and the wiring, together with the spring clip assembly, can transmit the current from the battery pack to the horn.
[0011] Preferably, the spring assembly includes an elastic plate, with a copper plate embedded at the bottom of the elastic plate. The copper plate is connected to the battery pack. The elastic plate is made of plastic to prevent the guide bolt from conducting electricity after contacting the spring assembly.
[0012] Preferably, the electrical box mounting column, stop pad, spring nut, guide bolt, locking washer and alarm mechanism are all in two sets, respectively assembled on both sides of the electrical box. The two sets can increase the stability of the electrical box when it is fixed.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a fall protection device for the electrical box of a marine electronically controlled diesel engine, which has the following advantages:
[0015] 1. The anti-fall protection device for the electrical control box of the marine electronic diesel engine is achieved by pre-welding stop blocks to the mounting column of the electrical box. During installation, the channel steel of the fixing bracket of the electrical box is equipped with spring nuts, and the springs fit perfectly into the countersunk holes of the stop blocks. Even if the fixing bracket of the electrical box becomes loose, the presence of the stop blocks on the mounting column will prevent the electrical box from falling. Furthermore, the springs also provide cushioning protection against falls, greatly reducing the risk of the electrical box falling due to loose connections, and preventing damage or breakage of wiring cables should the electrical box fall.
[0016] 2. The anti-fall protection device for the electrical box of the marine electronically controlled diesel engine, through the added alarm mechanism, when the guide bolt is inserted into the inside of the stop pad, it will abut against the spring group and fall down, and then connect to the battery pack, thereby energizing the horn to produce an alarm, warning that the assembly position of the electrical box is loose.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] This invention provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2 A fall protection device for a marine electronic control diesel engine electrical box includes: an electrical box mounting column 1, a channel steel bracket 2, and a stop block 3. The channel steel bracket 2 is connected to the electrical box mounting column 1 via a pipe clamp. The electrical box mounting column 1 and the channel steel bracket 2 can be connected to the electrical box. The channel steel bracket 2 is externally fitted with channel steel, and a spring nut 4 is externally fitted with the channel steel. A guide bolt 5 is internally connected to the spring nut 4. A locking washer 6 is fitted between the guide bolt 5 and the spring nut 4. The top of the stop block 3 has a countersunk hole, which is aligned with the axis of the spring nut 4 and the guide bolt 5. The guide bolt 5, together with the stop block 3, can prevent the electrical box from falling. The locking washer 6 can increase the stability of the connection between the guide bolt 5 and the spring nut 4.
[0024] Please see Figure 3 and Figure 4 The stop pad 3 is equipped with an alarm mechanism 7. The spring nut 4 includes a nut with a spring at the bottom and the spring is welded to the nut. The spring can dampen the nut after it moves. A damping rod can be installed between the spring and the nut to increase the damping effect. The spring at the bottom of the spring nut 4 is bolted to the inside of the stop pad 3. The spring nut 4 makes elastic contact with the spring and plays the role of 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.
[0025] The alarm mechanism 7 includes a horn 71 and a battery pack 73. A circuit 72 is installed between the horn 71 and the battery pack 73 and on the right side of the horn 71. A spring assembly 74 is installed on the right side of the battery pack 73. The horn 71 can be powered to sound. The circuit 72, together with the spring assembly 74, can transmit the current from 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. The battery can power the alarm device.
[0026] The spring assembly 74 includes an elastic plate with a copper plate embedded at the bottom. The copper plate is connected to the battery pack 73. The elastic plate is made of plastic to prevent the guide bolt 5 from conducting electricity after contacting the spring assembly 74. The electrical box mounting column 1, the stop pad 3, the spring nut 4, the guide bolt 5, the locking washer 6, and the alarm mechanism 7 are all in two sets, respectively assembled on both sides of the electrical box. The two sets can increase the stability when fixing the electrical box.
[0027] During installation, the installation position of the channel steel bracket 2 of the electrical box is calculated in advance, and the locking pads 3 are welded at the corresponding positions of the electrical box mounting column 1. Before hoisting the electrical box, the spring nuts 4 are first installed on the channel steel bracket 2. When hoisting the electrical box assembly including the electrical box and the mounting bracket, the position of the electrical box is adjusted so that the springs under each spring nut 4 are aligned with the countersunk holes of the locking pads 3, and then the electrical box assembly is lowered.
[0028] At this time, the channel steel bracket 2 and the stop pad 3 are in elastic contact through the spring, which plays the role of 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 electrical box falls due to loose bolts caused by prolonged 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 stop pad 3, it will abut against the spring assembly 74 and descend, thereby energizing the battery pack 73, which will then energize the horn 71 to produce a sound, warning that the electrical box is loosely assembled.
