Description

Technical Field

[0001] The present invention relates to the technical field of power failure protection, in particular to a power failure protection device based on a DEH control system. Background Art

[0002] The power failure protection device based on the DEH control system is a protection device specially designed for generator sets. The DEH control system is an advanced digital electro-hydraulic control system, which is usually used for the control and protection of large generator sets. This power failure protection device uses the high-precision control and real-time monitoring functions of the DEH system to quickly and reliably respond to power failure events in the power system and protect the generator sets and related equipment. The existing power failure protection device generally protects the control switch to ensure that the DEH control system can operate completely. The existing protection device often uses threaded installation and disassembly during installation and disassembly, which is very inconvenient.

[0003] The patent with patent number CN202122640942.4 discloses a power-off protection device based on a DEH control system. The patent adds a fuse terminal at the fan power input end to solve the power-off malfunction caused by overcurrent due to fan failure. The reliability of the protection signal is improved by using the power-off relay to directly output the power-off signal, and the malfunction of the protection is prevented. The first through hole and the second through hole are passed through the hand-held cylinder in sequence. At this time, the cross screw is moved downward through the cylinder to the guide arc groove on the limit plate body. After the limit plate body is in a parallel state, one end of the cross screw passes through the first threaded through hole, and then the cross screw is rotated. The cross screw drives the limit plate body to move toward the lower surface of the mounting plate body, thereby quickly installing the relay and the fuse terminal to the mounting plate body, thereby improving the fixed installation efficiency. Although the patent solves the above problems, there is still a problem that the device cannot be protected as a whole. Therefore, a power-off protection device based on a DEH control system is proposed to solve the above problems. Summary of the invention

When the power-off switch is not powered on, in order to protect the power-off switch, the top cover is first opened, and then the two ends of the protective sliding cover are aligned with the slide grooves between the card plate and the mounting bracket and inserted. When the protective sliding cover is inserted into the mounting bracket, the positioning lever is pressed, and the positioning lever moves backward to drive the umbrella-shaped propulsion block to move backward. When the umbrella-shaped propulsion block moves, its inclined surface and the front inclined surface of the locking pin conflict with each other. Guided by the inclined surface, the umbrella-shaped propulsion block drives the locking pin to move downward. At this time, the umbrella-shaped propulsion block moves to the rear side of the locking pin. After the locking pin is reset by the spring, its rear side plane hooks the umbrella-shaped propulsion block. The front plane of the block is pressed, thereby fixing the umbrella-shaped pushing block and the positioning push rod, and the rear end of the positioning push rod passes through the locking hole provided on the card plate and is inserted into the locking holes provided on both sides of the protective sliding cover, thereby fixing the protective sliding cover; when it is necessary to check the power-off switch, the disassembly push rod is pressed, and the disassembly push rod moves backward to squeeze the inclined groove provided on the locking pin, and the locking pin is pushed downward by the guidance of the inclined surface of the inclined groove. At this time, the umbrella-shaped pushing block loses the locking of the locking pin, and the spring on the front side of the umbrella-shaped pushing block drives it to move forward and reset, and then the spring at the bottom end of the locking pin lifts the locking pin, and when the locking pin is lifted, the disassembly push rod is driven to move forward and reset through the guiding force of the inclined groove, and at this time the positioning push rod cannot be inserted into the locking hole provided on the protective sliding cover.

When the weather is too humid, the moisture that penetrates into the mounting frame is absorbed by the solid dehumidifier through the partition net. After pressing the disassembly push rod, the disassembly push rod drives the locking pin and the transmission rod to move downward, and the transmission rod drives the connecting rod and the baffle to move downward. When the baffle moves downward, the inlet loses the obstruction of the baffle. At this time, the solid dehumidifier placed in the material frame in advance falls into the storage box due to gravity, and the transmission rod also drives the sealing plate to move downward, so that the old solid dehumidifier falls into the bottom of the storage box from the groove opened on the partition, and the new solid dehumidifier fills the top of the storage box. At the same time, the downward movement of the baffle will drive the outlet opened by itself to move down and align with the outlet second. At this time, the old solid dehumidifier at the bottom of the storage box will slide toward the outlet due to the inclined surface of the discharge inclined block, and the old solid dehumidifier will be discharged from the outlet, thereby completing a round of replacement of the solid dehumidifier.

[0007] Preferably, the conductive device includes a conductive rod, an insulating connecting shaft, a switch rod, an insulating fixing plate, and a conductive wire.

When the power system suddenly loses power or suddenly resumes power, untimely control may easily cause leakage of the device. The switch rod is rotated to connect the conductive rod and the conductive wire through the switch rod. When the current is conducted, it is blocked by the insulating connecting shaft, the insulating fixing plate and the insulating toggle plate to avoid contact with the mounting frame. The disassembly push rod is pressed, and the disassembly push rod drives the toggle rod to be pressed down through the locking pin and the transmission rod.

When the positioning push rod cannot be inserted into the lock hole opened on the protective sliding cover, the top cover is opened to pull out the protective sliding cover, which is easy to disassemble and further improves the convenience of the device.

[0010] 2. In the power-off protection device based on the DEH control system, the moisture that penetrates into the mounting frame is adsorbed by the solid dehumidifier through the partition net, thereby reducing the air humidity inside the mounting frame and preventing moisture from further penetrating into the power-off switch and causing damage to the power-off switch. The solid dehumidifier slides toward the discharge port through the inclined surface of the unloading inclined block, and the old solid dehumidifier is discharged from the discharge port. When the protective sliding cover is disassembled, a round of replacement is completed at the same time, which saves time, improves the replacement efficiency, and makes the operation more convenient. At the same time, it also avoids the old solid desiccant from accumulating in the storage box, thereby improving the dehumidification efficiency and further promoting the protection effect of the device.

[0011] 3. The power-off protection device based on the DEH control system rotates the switch rod to connect the conductive rod with the conductive wire through the switch rod. The current can be discharged from the power-off switch and introduced into the ground or wall through the conductive wire for consumption, thereby avoiding leakage damage to the device. When the current is conducted, it is blocked by the insulating connecting shaft, the insulating fixing plate and the insulating toggle plate to avoid contact with the mounting frame, thereby preventing the charge from being conducted to the mounting frame and causing danger. The toggle rod drives the switch rod to rotate and connect with the conductive wire through the insulating toggle plate, thereby preventing the conductive device from conducting electricity under normal conditions and affecting the operation of the power-off switch. When a problem occurs in the power system and the power-off switch leaks, and the staff repairs it, the conductive wire takes the lead in conducting the current, thereby ensuring the safety of the staff.
