Description

Technical Field

[0001] The utility model relates to fire fighting equipment, in particular to a detachable fire fighting pump. Background Art

[0002] A fire pump is a type of water pump, generally used for fire water supply, but can also be used in other water supply systems. Compared with ordinary water pumps, fire pumps are more stable in operation, more durable, and made of corrosion-resistant materials. They can operate continuously for a long time and be parked for a long time without damage. However, like ordinary water pumps, there are some wearing parts inside, such as mechanical seals. In order to ensure the reliability of the fire protection system after a period of operation, even if the mechanical seals have not been damaged, they should be maintained and replaced to minimize the failure rate.

[0003] At present, most of the fire pumps on the market use bolts and nuts to lock the flange between the motor and the pump body together through a large number of bolts and nuts. Although this locking method is reliable, the removal and installation of nuts and bolts is time-consuming and labor-intensive, which greatly affects the efficiency of fire pump maintenance or repair.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a detachable fire pump to overcome the above technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A detachable fire pump comprises a pump body, wherein a pump chamber is provided inside the pump body, a rotating shaft rod is movably connected to the center of the pump chamber, an impeller is fixedly connected to the rotating shaft rod, a top plate is fixedly connected to the top of the outer surface of the pump body, a bottom plate is provided on the top plate, a detachable mechanism is provided between the bottom plate and the top plate, the detachable mechanism comprises a top groove equidistantly provided on the top plate, a groove is provided on the top of one side of the inner surface of the top groove, a moving rod is slidably connected in the groove, a fixing block is fixedly connected to one end of the moving rod, a limiting rod is provided in the top groove, a fixing groove 1 and a fixing groove 2 corresponding to the fixing block are respectively provided on the outer surface of the limiting rod, a limiting block is welded on the top end of the limiting rod, square holes are equidistantly provided on the bottom plate, a limiting groove is provided on the inner surface of the square hole, the top end of the bottom plate is connected to a motor plate through a support frame, and a driving mechanism is provided on the motor plate.

[0008] Furthermore, in order to make the impeller rotate, the driving mechanism includes a driving motor fixedly connected to the motor plate, the output end of the driving motor is connected to the driving shaft by bolts, a shell is provided on the outer surface of the driving motor, heat dissipation holes are opened at equal distances on both ends of the outer surface of the shell, and sound insulation cotton is fixedly connected to the inner surface of the shell.

[0009] Furthermore, in order to make the shaft driven by the rotating shaft rotate synchronously, one end of the rotating shaft extends outside the pump body and is connected to a coupling, and one end of the coupling away from the rotating shaft is connected to the driving shaft.

[0010] Furthermore, in order to facilitate the rotation of the limit rod, an adjustment groove is opened on the bottom of one side of the inner surface of the top groove, one end of the adjustment groove extends outside the top plate, and an adjustment rod is welded on the bottom of the outer surface of the limit rod, and one end of the adjustment rod passes through the adjustment groove.

[0011] Furthermore, in order to allow water to flow in the pump cavity, a water inlet pipe is welded to one end of the outer surface of the pump body, and a water outlet pipe is fixedly connected to the other end of the outer surface of the pump body. The water inlet pipe and the water outlet pipe are interconnected with the pump cavity.

[0012] Furthermore, in order to limit the position of the limiting rod, a spring is sleeved on the outer surface of the moving rod, and two ends of the spring are fixedly connected to the fixing block and the groove respectively.

[0013] Furthermore, in order to facilitate the sliding of the moving rod, the other end of the moving rod extends outside the top plate and is fixedly connected to the pull rod.

[0014] Furthermore, in order to stabilize the pump body on the ground, a support ring is welded on the bottom end of the pump body, and fastening bolts are threadedly connected at equal distances on the bottom end of the support ring.

[0015] The beneficial effects of the utility model are:

[0016] 1. When assembling the fire pump, first, connect the rotating shaft and the driving shaft through the coupling, and align the top plate and the bottom plate with each other. Since the fixed block is in the fixed groove one, the limit block is placed in the square hole. Secondly, pull the pull rod to compress the spring and move the fixed block from the fixed groove one to the groove. At this time, move the adjusting rod so that the limit rod rotates synchronously with the adjusting rod. The rotation of the limit rod drives the limit block to move into the limit groove, so that the bottom plate and the top plate are in close contact. The rotation of the limit rod makes the fixed groove two and the fixed block flush. At this time, release the pull rod. Under the action of the spring elasticity, the fixed block in the groove moves into the fixed groove two, so that the limit rod and the top groove are locked, further improving the efficiency of installation.

[0017] 2. When disassembling the fire pump, first, pull the pull rod to compress the spring, so that the fixed block moves from the fixed groove 2 to the groove. At this time, move the adjusting rod in the opposite direction, thereby driving the limit rod to rotate in the opposite direction. The reverse rotation of the limit rod causes the limit block to move from the limit groove to the square hole. Due to the reverse rotation of the limit rod, the fixed groove 1 is flush with the fixed block. At this time, release the pull rod, and under the action of the spring elasticity, the fixed block in the groove moves into the fixed groove 1, thereby locking the limit rod and the top groove, effectively avoiding the limit block from rotating during the disassembly process, thereby affecting the disassembly efficiency.

At this time, the adjusting rod 31 is moved, so that the limit rod 22 rotates synchronously with the adjusting rod 31. The rotation of the limit rod 22 drives the limit block 23 to move into the limit groove 19, so that the bottom plate 17 is in close contact with the top plate 20. The rotation of the limit rod 22 makes the fixed groove 25 flush with the fixed block 27. At this time, the pull rod 30 is released, and under the elastic action of the spring 29, the fixed block 27 in the groove 26 moves to the fixed groove The second groove 25 is moved in the second groove 25, thereby locking the limit rod 22 and the top groove 21, further improving the installation efficiency. When disassembling the fire pump, first, pull the pull rod 30 to compress the spring 29, so that the fixed block 27 moves from the fixed groove 25 to the groove 26. At this time, the adjusting rod 31 is moved in the opposite direction, thereby driving the limit rod 22 to rotate in the opposite direction. The reverse rotation of the limit rod 22 causes the limit block 23 to move from the limit groove 19 to the square hole 18. Due to the reverse rotation of the limit rod 22, the fixed groove 1 24 is flush with the fixed block 27. At this time, release the pull rod 30, and under the elastic action of the spring 29, the fixed block 27 in the groove 26 moves into the fixed groove 1 24, thereby locking the limit rod 22 and the top groove 21, effectively avoiding the limit block 23 from rotating during the disassembly process, thereby affecting the disassembly efficiency.
