Description

Technical Field

[0001] The invention belongs to the technical field of ship power supply, and in particular relates to a ship electrical high and low voltage power supply device. Background Art

[0002] With the rapid development of the shipping industry, a large number of new types of ships such as refrigerated container ships, engineering ships, and luxury cruise ships have emerged. The number of ship electrical equipment has continued to increase, and the capacity of power stations has also greatly increased. Circuit breakers play a vital role in ship electrical high and low voltage power supply devices. In the high-voltage power supply part, when the current increases abnormally and exceeds the rated value of the circuit breaker, whether it is due to overload caused by sudden equipment failure or a short circuit in the system, the circuit breaker can respond quickly and automatically cut off the circuit to prevent irreparable damage to expensive high-voltage electrical equipment and power supply lines due to overcurrent. In terms of low-voltage power supply, it can also trip in time when the current exceeds the safe range to protect low-voltage electrical devices such as lighting systems and control equipment, and avoid dangerous situations such as fire caused by overcurrent.

[0003] However, in the existing power supply boxes, most of the cooling devices have poor air circulation effect when blowing, resulting in the ineffective discharge of heat in the box and the continuous increase in temperature. This will not only affect the normal operation of the equipment, but may even cause equipment damage or cause a fire. The main reason lies in the defects in the structural design of traditional cooling devices. For example, the fan position is unreasonable, the airflow path design is unscientific, and the cooling duct is narrow, all of which make the airflow circulation efficiency low and unable to effectively remove the heat in the box. Summary of the invention

[0004] The object of the present invention is to provide an electrical high and low voltage power supply device for ships. By providing a heat dissipation mechanism, when the electrical control cabinet needs to be cooled, the motor can be driven to drive the rotating shaft and multiple impeller blades. The multiple rotating impeller blades form centrifugal wind force, and the external air is gathered above the impeller blades under the guidance of multiple inclined plates and blown out, forming a strong blowing effect. The external airflow is filtered through a dust filter cover before being sucked into the support frame, effectively preventing dust in the external air from flowing into the device through the dust. After the airflow is blown into the electrical control cabinet, it is discharged through the filter plate on the opening, and the heat inside the device is taken out to dissipate the heat inside the device, avoiding damage to electrical components caused by excessive temperature. At the same time, the moisture-proof plate can absorb water molecules in the external air, so as to have a certain moisture-proof effect, which solves the problem that the airflow circulation effect of most heat dissipation devices is poor during blowing, resulting in the inability to effectively discharge the heat in the box.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] Furthermore, a hinge assembly is arranged between the wind guide plate and the fixed frame 1, and the hinge assembly includes two hinge rods fixedly connected to two rotating rods. There are four hinge rods, and the four hinge rods are respectively arranged on the front end and the rear end of the two rotating rods. Four connecting blocks are fixedly connected to the top surface of the fixed frame 1.

[0011] Furthermore, each of the four hinged rods is hinged with a hinged block 1, each of the four connecting blocks is hinged with a hinged block 2, and a spring 1 is fixedly connected between the hinged block 1 and the hinged block 2.

[0012] Furthermore, the installation mechanism includes sliding grooves which are both opened on the inner walls of the fixed frame 1 and the fixed frame 2, and the inner walls of the two sliding grooves are respectively slidably connected to the two moisture-proof plates.

[0013] Furthermore, the left and right sides of the fixed frame one and the fixed frame two are fixedly connected with fixed frames, and sliding rods are passed through several of the fixed frames.

[0014] Furthermore, a spring 2 is wound around the outer walls of a plurality of the sliding rods, one end of the spring 2 is fixedly connected to the inclined block, and the other end of the spring 2 is fixedly connected to the fixing frame.

[0015] The present invention has the following beneficial effects:

[0016] By providing a heat dissipation mechanism, when the electrical control cabinet needs to be cooled, the motor can be driven to drive the rotating shaft and multiple impeller blades. The multiple rotating impeller blades form centrifugal wind force, and the external air is gathered above the impeller blades under the guidance of multiple inclined plates and blown out, forming a strong blowing effect. The external airflow is filtered through the dust filter cover before being sucked into the support frame, effectively preventing dust in the external air from flowing into the device through the dust.

When the air guide plate flips upward, the rotating rod and the fixing rod will also rotate accordingly, so that the spring 1 is stretched. After the temperature inside the electrical control cabinet drops, the motor can be turned off to supply air to the inside of the device. At this time, with the cooperation of the hinge rod, the connecting block, the hinge block 1 and the hinge block 2, the stretched spring 1 is reset, so that the two air guide plates flip downward and quickly reset. Under the pull of the two springs 1, the two fixing plates quickly hit the top surface of the fixing frame 1, so that the rubber fixing plate will vibrate when hitting the fixing frame 1, so that the dust accumulated on the dust filter cover is shaken off, so as to prevent excessive dust accumulation from affecting the circulation effect of the airflow.

[0018] By providing an installation mechanism, the fixing frame and the sliding groove cooperate with each other, so that the inclined block can clamp the moisture-proof board after sliding into the inclined groove to fix the moisture-proof board, and the moisture-proof board can be replaced after the moisture-proof effect decreases. At this time, the two sliding rods can be pulled outward to make the inclined block move away from the inclined groove.

Air is supplied inside the device. At this time, with the cooperation of the hinge rod 35, the connecting block 36, the hinge block 1 37 and the hinge block 2 38, the stretched spring 1 39 is reset, so that the two air guide plates 32 are flipped downward and quickly reset. Under the pulling of the two springs 1 39, the two fixed plates 34 quickly hit the top surface of the fixed frame 1 23, so that the fixed frame 1 23 will vibrate when the rubber fixed plate 34 hits the fixed frame 1 23, so that the dust accumulated on the dust filter cover 24 is shaken off to prevent excessive dust accumulation from affecting the circulation effect of the airflow.

[0036] By providing the mounting mechanism 4, the fixing frame 42 and the slide groove 41 cooperate with each other, so that the inclined block 44 can clamp the moisture-proof plate 291 after sliding into the inclined groove 46 to fix the moisture-proof plate 291. The moisture-proof plate 291 can be replaced after the moisture-proof effect decreases. At this time, the two sliding rods 43 can be pulled outward to make the inclined block 44 away from the inclined groove 46. At this time, the spring 2 45 is squeezed. After the moisture-proof plate 291 is pulled out for replacement, the spring 2 45 can be loosened. With the cooperation of the fixing frame 42, the inclined block 44 is reset to slide into the inner wall of the inclined groove 46 to re-fix the moisture-proof plate 291, thereby improving the replacement efficiency of the moisture-proof plate 291 and facilitating the maintenance personnel to quickly and conveniently replace the moisture-proof plate 291.
