A marine low-speed engine control box

Abstract

This invention discloses a marine low-speed engine control box, including a low-speed engine control box body installed on a ship. The back panel inside the box contains several adjustment modules for adjusting the operating parameters of the low-speed engine, a sealing lifting mechanism for ensuring the waterproofing of the wiring terminals of the adjustment modules, and an adjustment mechanism for driving the sealing lifting mechanism up and down. The invention uses a positioning pin to fix the relative position of the connecting block and the clamping block. Then, by lowering the lifting mechanism, the connecting block drives the clamping block and the lifting block to descend along the fixed seat, causing the sealing ring to descend and detach from the surface of the adjustment module. This facilitates personnel replacement and maintenance of the adjustment module. Furthermore, by manually pulling the positioning pin, the positioning pin can be disengaged from the clamping block, allowing any number of clamping blocks and the lifting block to descend via the lowering mechanism.

Description

Technical Field

[0001] This invention relates to the field of marine low-speed engine control cabinet technology, and in particular to a marine low-speed engine control box. Background Technology

[0002] Low-speed engines refer to diesel engines with a speed below 300 rpm, which are usually used as the propulsion power for ships. In order to facilitate remote control of low-speed engines, a diesel engine control box is usually installed in the ship's bridge. The low-speed engine and the various control elements in the control box are connected by cables, thereby realizing remote control of the low-speed engine through the control box. However, during the ship's navigation, the waves on the water surface cause the ship to roll, which in turn causes the cables connected to the control elements in the control box to swing accordingly. During the swing, the connection between the cable and the control element can easily become loose or fall off, making it impossible for the control box to remotely control the low-speed engine. Summary of the Invention

[0003] The purpose of this invention is to reduce the impact of the above-mentioned situation and to provide a marine low-speed engine control box.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a marine low-speed engine control box, comprising a low-speed engine control box body installed on a ship, wherein a plurality of adjustment modules for adjusting the operating parameters of the low-speed engine, a sealing lifting mechanism for ensuring the waterproofing of the wiring terminals of the adjustment modules, and an adjustment mechanism for driving the sealing lifting mechanism to move up and down.

[0005] The sealing lifting mechanism includes a lifting block located at the terminal of the adjustment module and capable of moving up and down. The lifting block has a vertical wire groove through which the power supply line passes at the terminal of the adjustment module. A clamping block that rotates horizontally and fits the wire in the wire groove is hinged to the lifting block. A vertical sealing ring that isolates the terminal of the adjustment module from the wire groove is fixed on the lifting block. The mechanism also includes a lifting component located inside the housing that moves up and down. A horizontal connecting block is fixed at the position of each row of clamping blocks on the lifting component. The connecting block has an extension with a positioning pin penetrating through the side of the lifting block.

[0006] As a further embodiment of the present invention, a fixing seat through the lifting block is fixed to the inner wall of the box, and a spring connected to the bottom surface of the lifting block is sleeved on the fixing seat.

[0007] As a further aspect of the present invention, the clamping block is provided with a sealing gasket that fits against the inner wall of the wire threading groove and the surface of the wire.

[0008] As a further embodiment of the present invention, two guide rods are symmetrically fixed to the bottom surface of the box body, which pass through several connecting blocks and are arranged vertically.

[0009] As a further embodiment of the present invention, a waterproof cover is fixed to the outer top surface of the box, the lifting component penetrates the top surface of the box and a portion of it is located in the waterproof cover, the adjustment mechanism includes a handle that penetrates the front surface of the waterproof cover and is placed horizontally, a vertically arranged turntable is fixed to the rear end face of the handle, the top of the rear surface of the turntable is a protruding cylindrical shape, and a square frame that is fitted onto the protruding part of the turntable and is placed horizontally is fixed to the lifting component.

[0010] As a further embodiment of the present invention, a sleeve fitted on the handle is fixed to the inner wall of the waterproof cover, and the end face of the sleeve is slidably connected to the surface of the turntable.

[0011] As a further embodiment of the present invention, the adjustment module is fixed to the inner wall of the box by bolts, and a locking block supporting the bottom of the adjustment module is fixed on the box.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The lifting block rises due to the elastic force of the spring on the fixed base, which in turn causes the sealing ring on the lifting block to tightly press against the wiring terminal of the adjustment module. In conjunction with the sealing gasket, the wires and the wire channel are also sealed, which can isolate the wiring terminal of the adjustment module and achieve waterproofing. Furthermore, by tightly pressing the sealing gasket against the wires and the wire channel, the relative position of the wires and the wire channel is fixed by the friction and elastic deformation between the sealing gasket and the wires, which prevents the wires connected to the wiring terminal of the adjustment module from falling off or corroding.

[0014] 2. The positioning pin is set to fix the relative position of the connecting block and the clamping block. Then, the lifting component descends to make the connecting block drive the clamping block and the lifting block to descend along the fixed seat, and drive the sealing ring to descend and disengage from the surface of the adjustment module. This makes it easy for personnel to replace and maintain the adjustment module. Furthermore, the positioning pin can be manually pulled out by the personnel to disengage from the clamping block, so that any number of clamping blocks and lifting blocks can be driven to descend by the lifting component.

[0024] 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.

[0025] Please see Figure 1-7 The present invention provides a technical solution: a marine low-speed engine control box, including a low-speed engine control box body 1 installed on the ship, and a plurality of adjustment modules 3 for adjusting the operating parameters of the low-speed engine, a sealing lifting mechanism for ensuring the waterproof position of the wiring terminals of the adjustment modules 3, and an adjustment mechanism for driving the sealing lifting mechanism to move up and down.

[0026] The effect it achieves is as follows: the adjustment module 3 is an existing diesel engine electronic governor dg6800, oil pressure regulator, valve clearance regulator, cylinder pressure regulator or other regulator, and is connected to the low-speed engine host through wires.

[0027] The sealing lifting mechanism includes a lifting block 14 located at the terminal of the adjustment module 3 and capable of moving up and down. A vertical wire groove 18 for the power supply line to pass through is provided on the lifting block 14 at the terminal of the adjustment module 3. A clamping block 17 that rotates horizontally and fits the wire in the wire groove 18 is hinged on the lifting block 14. A vertical sealing ring 12 that isolates the terminal of the adjustment module 3 from the wire groove 18 is fixed on the lifting block 14. The mechanism also includes a lifting component 2 located inside the housing 1 and capable of moving up and down. A horizontal connecting block 9 is fixed on the lifting component 2 at the position of each row of clamping blocks 17. An extension 20 with a positioning pin 13 penetrating through the side of the lifting block 14 is provided on the connecting block 9.

[0028] The effect it achieves is as follows: Figure 3 and Figure 5 As shown, Figure 5 The wire passing through the cable groove 18 is for connecting the low-speed motor. The cable groove 18 is designed to fit the surface of the wire, and the insulating rubber layer on the surface of the wire can completely adhere to the inner surface of the cable groove 18 when the wire is compressed, achieving waterproofing and moisture protection. When the clamping block 17 is attached to the lifting block 14, the surface of the clamping block 17 presses against the surface of the wire, forcing the surface of the wire to fit tightly against the inner wall of the cable groove 18. The clamping block 17 and the lifting block 14 are fixed together by bolts. The sealing ring 12 is made of hard rubber, which can completely fit near the terminal of the adjustment module 3 when the lifting block 14 rises, achieving connection... Air isolation at the wire end prevents moisture from corroding the terminal, and the clamp 17 tightly fits the wire. Before the lifting block 14 rises, the wire is first connected and fixed to the terminal of the adjustment module 3. Therefore, as the lifting block 14 rises, the originally taut wire between the lifting block 14 and the adjustment module 3 becomes loose. That is, the wire connected to the terminal of the adjustment module 3 will not become loose due to gravity and ship swaying. The positioning pin 13 passes through the extension 20 and the lifting block 14 to ensure that when the lifting component 2 drives the connecting block 9 to descend, it also drives the lifting block 14 and the clamp 17 to descend accordingly.

[0029] As a further embodiment of the present invention: such as Figure 5 As shown, a fixed seat 15 is fixed to the inner wall of the housing 1, which passes through the lifting block 14. A spring 16 connected to the bottom surface of the lifting block 14 is sleeved on the fixed seat 15.

[0030] The effect it achieves is: the set spring 16, as... Figure 6 The state shown is the compressed state, which makes it easy for the lifting block 14 to rise through the spring force of the spring 16, thereby making the sealing ring 12 tightly fit around the wiring terminal of the adjustment module 3, and the lifting block 14 can still descend a certain distance along the fixed base 15.

[0031] As a further embodiment of the present invention: such as Figure 5 As shown, the clamping block 17 is provided with a sealing gasket 19 that fits the inner wall of the wire groove 18 and the surface of the wire.

[0032] The effect achieved is as follows: the sealing gasket 19 is designed to fit tightly against the surface of the wire when the clamp 17 is attached to the lifting block 14 and the surface of the wire. The sealing gasket 19 is made of silicone material. When it is tightly attached to the surface of the wire, it can not only increase the friction to prevent the wire from shaking up and down, but also fill the gap between the wire and the wire groove 18 through the elastic deformation of the sealing gasket 19, so as to achieve waterproof, moisture-proof and air-isolated isolation.

[0033] As a further embodiment of the present invention: such as Figure 2As shown, two guide rods 4, which pass through several connecting blocks 9 and are vertically arranged, are symmetrically fixed on the bottom surface of the inner side of the box 1.

[0034] The effect it achieves is that the guide rod 4 ensures that the connecting block 9 and the lifting component 2 can only move up and down.

[0035] As a further embodiment of the present invention: such as Figure 6 As shown, a waterproof cover 5 is fixed to the top surface of the box 1. The lifting component 2 penetrates the top surface of the box 1 and is partially located in the waterproof cover 5. The adjustment mechanism includes a handle 6 that penetrates the front surface of the waterproof cover 5 and is placed horizontally. A turntable 7 is fixed to the rear end face of the handle 6. The top of the rear surface of the turntable 7 is a protruding cylindrical shape. A square frame 10 is fixed to the lifting component 2 and is placed horizontally on the protruding part of the turntable 7.

[0036] The effect it achieves is as follows: Figure 6 and Figure 7 As shown, the waterproof cover 5 is designed to prevent moisture from entering the housing 1 through the gap between the lifting component 2 and the housing 1. The turntable 7 is provided with a cylindrical protrusion embedded in the square frame 10 and sliding horizontally back and forth inside the square frame 10. The turntable 7 is rotated by rotating the handle 6. The cylindrical protrusion on the turntable 7 is connected to the square frame 10. When the turntable 7 rotates, the cylindrical protrusion on the turntable 7 slides in the square frame 10. As the turntable 7 rotates, the height of the cylindrical protrusion on the turntable 7 changes accordingly, thereby realizing that the square frame 10 changes with the height of the cylindrical protrusion. That is, the circular motion of the turntable 7 is transformed into the up and down movement of the lifting component 2. A horizontal pin is passed through the handle 6. After the handle 6 is rotated at a certain angle, the lifting component 2 drops a certain distance accordingly. The pin is inserted into the front surface of the waterproof cover 5 to fix the position of the handle 6. At this time, under the action of the positioning pin 13, the connecting block 9 drives the lifting block 14 to drop until the sealing ring 12 is separated from the surface of the adjustment module 3.

[0037] As a further embodiment of the present invention: such as Figure 7 As shown, a sleeve 8 is fixed to the inner wall of the waterproof cover 5 and is sleeved on the handle 6, and the end face of the sleeve 8 is slidably connected to the surface of the turntable 7.

[0038] The effect it achieves is that the sleeve 8 facilitates the support of the handle 6, ensuring that the handle 6 will not swing during rotation, and by contacting the surface of the turntable 7, it can prevent the handle 6 from wobbling back and forth.

[0039] As a further embodiment of the present invention: such as Figure 5 As shown, the adjustment module 3 is fixed to the inner wall of the housing 1 by bolts, and the housing 1 is fixed with a locking block 11 that supports the bottom of the adjustment module 3.

[0040] The effect achieved is that the set locking block 11 ensures the support of the bottom of the adjustment module 3, and the set bolts ensure that the adjustment module 3 will not detach from the back plate of the box 1 due to the swaying of the ship.

[0041] The working principle of this device is as follows: The adjustment module 3 and the inner wall of the housing 1 are connected by bolts. Rotating the handle 6 lowers the lifting component 2 and the connecting block 9, thereby causing the upper end face of the sealing ring 12 to detach from the surface of the adjustment module 3. The low-speed machine and the corresponding terminal of the adjustment module 3 are connected by wires. The clamp 17 is opened, and the wire passes through the wire groove 18 and the sealing ring 12. Then, the clamp 17 is rotated so that the sealing gasket 19 on the clamp 17 abuts against the wire in the wire groove 18. The relative position of the clamp 17 and the lifting block 14 is fixed by bolts. The pin on the handle 6 is pulled out. Under the action of the spring force of the spring 16, the lifting block 14, the connecting block 9, and the lifting component 2 are driven to rise until the upper end face of the sealing ring 12 abuts against the surface of the adjustment module 3, achieving waterproofing and moisture protection.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
