3results about How to "Facilitate maintenance" patented technology

This utility model belongs to the field of fire protection equipment technology, specifically a mechanical fire hydrant water pressure abnormality warning device, including a warning device housing; a siphon pipe is connected to one side of the warning device housing, and a support column is fixedly connected between the top and bottom of the inner wall of the warning device housing. A piston plate is slidably connected to the surface of the support column, and a return spring is sleeved on the surface of the support column. When water enters the warning device housing through the piston plate, the water will cause the piston plate to float. When the water pressure is greater than the threshold, the piston plate moves upward, thereby causing the sliding insulating light rod and the trigger conductive block to move away from the conductive plug block, the circuit is broken, and the warning light goes out. When the water pressure is less than the threshold, the return spring causes the piston plate to move downward, the trigger conductive block moves into the conductive plug block, the circuit is connected, and the warning light illuminates. The overall structure is simple and easy to install, thereby improving the efficiency of inspection.

This utility model provides a bidirectional speed limiter with an overspeed protection structure, relating to the field of safety protection equipment technology. It includes a base and a mounting bracket. A connecting bracket is fixedly mounted on the surface of the base. The bidirectional speed limiter body is disposed on the inner side of the mounting bracket, and a connecting seat is disposed on the inner side of the connecting bracket. In this utility model, a protrusion is provided on the lower surface of the mounting bracket, and a matching groove is formed on the side of the connecting seat. This allows the mounting bracket to slide along the groove and achieve initial positioning. Then, the motor is started, causing its output end to drive the bidirectional lead screw to rotate, causing the mounting block to move the limiting rod, allowing the limiting rod to insert into the limiting hole, thereby limiting and fixing the bidirectional speed limiter body. When maintenance is required, the motor is reversed, causing the limiting rod to retract from the limiting hole. Simultaneously, the mounting bracket can easily slide out along the groove, facilitating quick disassembly of the bidirectional speed limiter body, significantly reducing maintenance difficulty and shortening maintenance time.

This utility model relates to the field of fire protection technology and discloses a fire sprinkler head assembly, including a base and an upper connecting pipe. A fixing ring is slidably connected to the inner bottom wall of the base, and a sealing plate is sleeved inside the fixing ring. A dynamic sealing component is inserted into the top of the fixing ring. An insert is fixedly connected to the bottom of the upper connecting pipe, and locking blocks are fixedly connected to both sides of the insert. A limit component is sleeved on the bottom surface of the insert. The dynamic sealing component includes a movable ring inserted into the top of the fixing ring, and several sets of support springs are fixedly connected to the top of the movable ring. A connecting ring is fixedly connected to the top of each support spring. This fire sprinkler head assembly, through the setting of the dynamic sealing component, achieves a dynamic sealing effect, effectively preventing leakage caused by pipeline pressure fluctuations or slight vibrations in non-fire conditions, ensuring long-term stable pressure within the pipeline, and improving the service life of the fire sprinkler head assembly.
