Description
Technical Field
[0001] This invention belongs to the technical field of marine power supply boxes, specifically relating to a backup power supply box for marine diesel engines. Background Technology
[0002] Diesel engine backup power boxes are typically installed on the hull of a ship. During installation, each wire needs to be connected to the corresponding electrical components inside the backup power box. In existing technology, due to limited space, the wires fixed to the hull must pass through the inlet hole on the back panel of the backup power box to connect to the internal electrical components. During the initial installation, because the wires are flexible and easily move, they are prone to slipping out of the inlet hole, becoming tangled, or being crushed by the power box. The untangling and installation of the wires takes a lot of time and is inefficient. In addition, the moisture-proof structure at the inlet is not perfect, allowing outside air to easily enter the power box along the wires, resulting in high humidity inside the power box and easy damage. Summary of the Invention
[0003] The purpose of this invention is to provide a marine diesel engine backup power box to solve the above-mentioned problems. It aims to address the issues in the prior art where, during the initial installation of a diesel engine backup power box, flexible wires are prone to movement, easily slipping out of the inlet hole, becoming tangled and twisted, or being crushed and damaged by the power box. The untangling and installation of the wires is time-consuming and inefficient. In addition, the moisture-proof structure at the inlet is not perfect, allowing outside air to easily enter the power box along the wires, resulting in high humidity inside the power box and easy damage.
[0004] The present invention achieves the above objectives through the following technical solutions:
[0005] A backup power supply box for a marine diesel engine includes an outer shell, a wiring board detachably connected to the back plate of the outer shell, and a heat dissipation assembly disposed on the inner side wall of the outer shell. A cavity is formed between the outer shell and the wiring board. A plurality of inlet holes are distributed on the outer shell and the wiring board. Each inlet hole is fitted with a support assembly for supporting the wires.
[0006] The support assembly includes an outer cylinder and an inner cylinder slidably connected inside the outer cylinder. The outer cylinder and the inner cylinder are connected by a first limiting member. Two clamping rods are symmetrically provided on the inner wall of the inner cylinder. The clamping rods are rotatably connected to the inner wall of the inner cylinder through a hinge seat. One end of the clamping rod extends from the wire outlet end of the inner cylinder and is connected to the inner cylinder through a second limiting member. The other end of the clamping rod is provided with a clamping plate for clamping the wire.
[0007] The outer cylinder, inner cylinder, and cavity are equipped with moisture-proof components.
[0008] As a further optimization of the present invention, the outer edge of the wiring board is provided with a pin plate, and the back plate of the outer shell is provided with a pin groove for engaging the pin plate. The wiring board, the pin groove and the outer shell are connected and fixed by a number of fixing bolts.
[0009] As a further optimization of the present invention, the moisture-proof component includes a moisture-proof pad provided at the inlet end of the inner cylinder and a plurality of air holes opened on the outer cylinder. The outlet ends of the air holes are all distributed inside the cavity, and the cavity is sealed with moisture-proof plates above and below the outer cylinder.
[0010] As a further optimization of the present invention, the moisture-proof board is in the form of a grid.
[0011] As a further optimization of the present invention, the moisture-proof mat is annular, the ring wall of the moisture-proof mat is folded, the outer wall of the moisture-proof mat is connected to the inner wall of the inner cylinder, and two openings are symmetrically opened on the inner wall side of the moisture-proof mat.
[0012] As a further optimization of the present invention, the heat dissipation component includes a heat dissipation fan embedded in the inner side wall of the outer casing, a gas delivery cylinder connected to the heat dissipation fan and located inside the outer casing, and at least one delivery pipe extending into the cavity and connected to the gas delivery cylinder.
[0013] As a further optimization of the present invention, the first limiting member includes a first fixing block disposed on the inner wall of the outer cylinder outlet side and a first fixing groove formed on the outer wall of the inner cylinder for cooperating with the first fixing block.
[0014] As a further optimization of the present invention, the second limiting member includes a second fixing block disposed on the end face of the inner cylinder outlet and a second fixing groove formed on the clamping rod for cooperating with the second fixing block. A torsion spring is sleeved on the central shaft of the hinge seat, and the two clamping plates are brought closer to each other by the torsion of the torsion spring.
[0015] As a further optimization of the present invention, the front panel of the outer casing is hinged with a cabinet door, and the front end face of the wiring board is provided with a plurality of electrical components for connecting wires.
[0016] The beneficial effects of this invention are as follows:
[0017] 1) When installing the outer shell, the support component clamps the wire and snaps it into the inlet hole, making it difficult for the wire to move out. The wire is neatly stored and is less likely to be bent, tangled or pressed by the outer shell. In addition, the inner cylinder supports the wire and the clamping plate holds the wire, which can eliminate the step of fixing the wire to the wiring board during wiring. The wire is easier to organize and install, and can save installation time.
[0018] 2) In this invention, some of the air entering the outer shell along the wire will enter the cavity through the air hole and be dried by the moisture-proof board. The remaining air will also be dried by the moisture-proof pad when it passes through the moisture-proof pad. This can more fully absorb the moisture in the air entering the outer shell along the wire to improve the drying effect.
[0019] 3) While dissipating heat from the inside of the outer shell, the heat dissipation structure of the present invention can also draw out the gas inside the cavity after it has been dried by the moisture-proof board through the delivery pipe, accelerate the gas flow inside the cavity, and make the small amount of moisture in the moisture-proof pad and moisture-proof board evaporate quickly, so that the moisture-proof pad and moisture-proof board can be kept dry for a long time, so as to achieve a long-term moisture-proof effect, reduce or even eliminate the need to replace the moisture-proof pad and moisture-proof board, and make it more convenient to use.
[0020] 4) In this invention, if the temperature of the gas drawn from the delivery pipeline is low, the gas can cool the cooling fan, which is more energy-efficient. Attached Figure Description

Detailed Implementation
[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0030] like Figure 1-8 As shown, a backup power supply box for a marine diesel engine includes an outer shell 101, a wiring board 102 detachably connected to the back plate of the outer shell 101, and a heat dissipation assembly disposed on the inner side wall of the outer shell 101. A cavity 103 is formed between the outer shell 101 and the wiring board 102. A plurality of wire inlet holes are distributed on the outer shell 101 and the wiring board 102, and a support assembly for supporting wires is snapped into each wire inlet hole.
[0031] The support assembly includes an outer cylinder 5 and an inner cylinder 6 slidably connected inside the outer cylinder 5. The outer cylinder 5 and the inner cylinder 6 are connected by a first limiting member. Two clamping rods 10 are symmetrically provided on the inner wall of the inner cylinder 6. The clamping rods 10 are rotatably connected to the inner wall of the inner cylinder 6 through a hinge seat 9. One end of the clamping rod 10 extends from the wire outlet end of the inner cylinder 6 and is connected to the inner cylinder 6 through a second limiting member. The other end of the clamping rod 10 is provided with a clamping plate 11 for clamping the wire.
[0032] The outer cylinder 5, inner cylinder 6, and cavity 103 are equipped with moisture-proof components.
[0033] Preferably, the outer edge of the wiring board 102 is provided with pin plates 3, and the back plate of the outer shell 101 is provided with pin grooves 2 for engaging the pin plates 3. The wiring board 102, the pin grooves 2 and the outer shell 101 are connected and fixed by a number of fixing bolts 4.
[0034] During daily use, such as Figure 5 As shown, some of the air entering the outer casing 101 along the wire will enter the cavity 103 through the air hole 15. At this time, the moisture-proof plate 19 dries this part of the air. The remaining part of the air will also be dried by the moisture-proof pad 14 when it passes through the moisture-proof pad 14. This can more fully absorb the moisture in the air entering the outer casing 101 along the wire, so as to improve the drying effect.
[0035] Preferably, the moisture-proof component includes a moisture-proof pad 14 disposed at the inlet end of the inner cylinder 6 and a plurality of air holes 15 opened on the outer cylinder 5. The air outlet ends of the air holes 15 are all distributed inside the cavity 103. Moisture-proof plates 19 are sealed inside the cavity 103 above and below the outer cylinder 5.
[0036] In this embodiment, the front panel of the outer shell 101 is hinged with a cabinet door 104, and the front end face of the wiring board 102 is provided with a plurality of electrical components 105 for connecting wires. The cabinet door 104 seals the outer shell 101, so that a sealed space is formed inside the outer shell 101, which can provide good protection for the wires and electrical components 105.
[0037] During installation, the wire can be extended from the inlet end of the inner cylinder 6 into the interior of the inner cylinder 6, pass through the moisture-proof pad 14, and extend out from the outlet end of the inner cylinder 6. Adjust the clamping rod 10 to adjust the position of the clamping plate 11 to clamp the wire. Install the wiring board 102 on the back plate of the outer shell 101, so that each outer cylinder 5 passes through the corresponding inlet hole on the outer shell 101 and the wiring board 102 respectively. Fix the outer shell 101 to the hull. Pinch the outlet end of the inner cylinder 6 and pull the inner cylinder 6 away from the wiring board 102 until the inner cylinder 6 and the outer cylinder 5 are fixed by the first fixing block 7 and the first fixing groove 8, then release it, that is, the positions of the outer cylinder 5 and the inner cylinder 6 are at an angle. Figure 5 As shown, the wires are then connected to the electrical component 105. When installing the outer casing 101, the outer cylinder 5 is snapped into the wire inlet hole, making it difficult for the wires to move out. The wires are neatly stored and are less likely to be bent, tangled, or pressed by the outer casing 101. In addition, the inner cylinder 6 supports the wires and the clamping plate 11 holds the wires, which eliminates the need to fix the wires to the wiring board 102 during wiring. The wires are easier to manage and install, saving installation time.
[0038] Furthermore, the moisture-proof board 19 is grid-shaped, which can more fully absorb moisture from the air to improve the drying effect.
[0039] Furthermore, the moisture-proof pad 14 is annular in shape, and the ring wall of the moisture-proof pad 14 is folded. The outer wall of the moisture-proof pad 14 is connected to the inner wall of the inner cylinder 6. Two openings 141 are symmetrically opened on the inner wall side of the moisture-proof pad 14. The wire passes through the center of the annular moisture-proof pad 14. The folded ring wall of the moisture-proof pad 14 can more fully absorb moisture in the air to improve the drying effect. When used together with the openings 141, it is convenient to adapt to wires of different thicknesses.
[0040] Furthermore, the heat dissipation assembly includes a heat dissipation fan 16 embedded in the inner wall of the outer casing 101, a gas delivery cylinder 17 connected to the heat dissipation fan 16 and located inside the outer casing 101, and at least one delivery pipe 18 extending into the cavity 103 and connected to the gas delivery cylinder 17.
[0041] During daily use, the cooling fan 16 can dissipate heat from the inside of the outer casing 101. Specifically, the gas delivery cylinder 17 draws in hot air from inside the outer casing 101 and delivers it to the outside. While the gas delivery cylinder 17 is drawing in hot air from inside the outer casing 101, the gas inside the cavity 103, which has been dried by the moisture-proof board 19, can be drawn in through the delivery pipe 18. When the temperature of the gas drawn in through the delivery pipe 18 is low, the cooling fan 16 can be cooled down. This operation can also accelerate the gas flow inside the cavity 103, allowing the small amount of moisture in the moisture-proof pad 14 and the moisture-proof board 19 to evaporate quickly, thus keeping the moisture-proof pad 14 and the moisture-proof board 19 dry for a long time. This achieves a long-term moisture-proof effect, reducing or even eliminating the need to replace the moisture-proof pad 14 and the moisture-proof board 19, making it more convenient to use.
[0042] Preferably, the first limiting member includes a first fixing block 7 disposed on the inner wall of the outer cylinder 5 at the outlet side and a first fixing groove 8 formed on the outer wall of the inner cylinder 6 for cooperating with the first fixing block 7. By engaging the first fixing block 7 inside the first fixing groove 8, the inner cylinder 6 and the outer cylinder 5 can be fixed, thereby restricting the movement of the inner cylinder 6 and preventing the inner cylinder 6 from moving back and forth relative to the outer cylinder 5 during daily use.
[0043] Preferably, the second limiting member includes a second fixing block 12 disposed on the end face of the cable outlet of the inner cylinder 6, and a second fixing groove 13 formed on the clamping rod 10 for cooperating with the second fixing block 12. A torsion spring is sleeved on the central shaft of the hinge seat 9, and the two clamping plates 11 are brought closer to each other by the torsion of the torsion spring. In a natural state, the two clamping plates 11 are as follows: Figure 4 As shown, the clamping plates 11 are close to each other. When the wire needs to pass between the two clamping plates 11, the operator manually pinches the end of the clamping rod 10 that extends out of the inner cylinder 6 and moves it towards each other, thus opening the two clamping plates 11 as shown. Figure 3 In the indicated state, the wire is then passed between the two clamping plates 11. The two clamping rods 10 are released, and the clamping plates 11 will move closer together under the torsion of the torsion spring, thus clamping the wire. The second fixing block 12 engages inside the second fixing groove 13, limiting the movement range of the clamping rods 10. This allows for adjustment of the positions of the clamping rods 10 and clamping plates 11 according to the thickness of the wire, facilitating the clamping of wires of different thicknesses. The above embodiments only illustrate several implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
