Description

Technical Field

[0001] The utility model relates to the technical field of fire pumps, in particular to a vertical single-stage fire pump. Background Art

[0002] Vertical single-stage fire pump is a fire-fighting appliance, mainly used for pressurized water supply in fire-fighting systems, and can also be used for mine water supply and drainage. It has high reliability, will not get stuck when restarted after being out of service for a long time, and has the characteristics of high efficiency, low vibration, and easy inspection.

[0003] The Chinese utility model patent with announcement number: CN215256938U specifically discloses a vertical single-stage fire pump that is easy to install. The vertical single-stage fire pump that is easy to install is provided with a support rod and a working rod, so that the moving slider drives the support plate that is rotated with the lifting column to move through the working rod, thereby realizing the adjustment operation of the inclination angle of the pump body.

[0004] However, due to its specific structure, the vertical single-stage fire pump cannot effectively absorb the noise generated by the motor during actual application. Long-term use can easily cause hearing loss to workers. In addition, the vertical single-stage fire pump, which is easy to install, is not equipped with a filter component. Long-term use may cause the water inlet of the fire pump to be blocked, and its practicality is poor. Utility Model Content

[0031] See also Figure 5 and Figure 6 The noise reduction component 15 in this embodiment specifically includes a silencer sleeve 1501 , a heat dissipation slot 1502 , a second groove 1503 , a fixing block 1504 , a spring 1505 , a moving block 1506 , and a pull rod 1507 .

[0032] Among them, a heat dissipation groove 1502 is opened on the outside of the silencer sleeve 1501, a groove 2 1503 is set on the outside of the silencer sleeve 1501, a fixed block 1504 is fixedly installed inside the groove 2 1503, a spring 1505 is fixedly installed on the outside of the fixed block 1504, a moving block 1506 is fixedly installed on the other end of the spring 1505, and a pull rod 1507 is fixedly installed on the outside of the moving block 1506.

[0033] On this basis, the groove 8 in this embodiment is matched with the pull rod 1507, and the pull rod 1507 penetrates the moving block 1506 and extends to the outside of the fixed block 1504. In this way, the groove 8 is matched with the pull rod 1507, and the pull rod 1507 penetrates the moving block 1506 and extends to the outside of the fixed block 1504. The pull rod 1507 can be pulled to deform the spring 1505, so that the pull rod 1507 is separated from the groove 8, and then the noise reduction component 15 can be quickly taken out, thereby realizing the rapid assembly of the noise reduction component 15.

[0034] Furthermore, the heat dissipation groove 1502 in this embodiment is located on the outside of the silencer sleeve 1501, and the silencer sleeve 1501 is located on the outside of the motor 7. The advantage is that the heat dissipation groove 1502 is designed so that the silencer sleeve 1501 does not affect the heat dissipation of the motor 7 after installation. Combined with the silencer sleeve 1501 being located outside the motor 7, it can effectively block the noise of the motor 7.

[0035] Furthermore, the cavity 2 in this embodiment is connected to the water outlet 10 and the water inlet 13, and the water outlet 10 and the water inlet 13 are connected by flanges. With this arrangement, water source enters the cavity 2 through the water inlet 13, and then passes through the water outlet 10, so that the normal use of the entire pump body can be achieved. With the water outlet 10 and the water inlet 13 being connected by flanges, the entire pump body can be easily connected to the water outlet pipe.

[0036] Furthermore, the sealing sleeve 1 11 in this embodiment is located outside the water outlet 10, and the sealing sleeve 2 14 is located outside the water inlet 13. In this arrangement, by using the sealing sleeve 1 11 and the sealing sleeve 2 14 on the outside of the water outlet 10 and the water inlet 13 respectively, the system provides double sealing protection, which helps to reduce the risk of leakage and ensure that the pump body will not overflow or leak during use, thereby improving the overall sealing performance.

[0037] Furthermore, the filter sleeve 16 in this embodiment is located inside the water inlet 13, and the filter sleeve 16 and the water inlet 13 are plug-connected. In this way, the filter sleeve 16 is located inside the water inlet 13, and it is difficult for debris in the water resources to enter or affect the water inlet 13, which can effectively prevent the water inlet 13 from being blocked during use, thereby affecting normal operation, and the filter sleeve 16 and the water inlet 13 are plug-connected, which is also convenient for later maintenance and replacement.

[0038] Furthermore, the positioning grooves 12 in this embodiment are provided with four identical ones, and the support column 3 is located outside the cavity 2. With such a configuration, the four identical positioning grooves 12 can realize the rapid positioning and installation of the entire pump body, and the design of the support column 3 also provides a certain protection capability for the cavity 2, thereby preventing the cavity 2 from shaking during use and causing tipping.

[0039] When the vertical single-stage fire pump formed based on the above scheme is in use, the groove 8 thereon is adapted to the pull rod 1507, and the pull rod 1507 is inserted through the movable block 1506 and extends to the outside of the fixed block 1504. The pull rod 1507 can be pulled to deform the spring 1505, so that the pull rod 1507 is disengaged from the groove 8, and then the noise reduction component 15 can be quickly taken out, thereby realizing the rapid assembly of the noise reduction component 15.

[0040] Furthermore, through the design of the heat dissipation groove 1502, the silencer sleeve 1501 does not affect the heat dissipation of the motor 7 after installation. In addition, the silencer sleeve 1501 is located outside the motor 7, thereby effectively blocking the noise of the motor 7.

[0041] Furthermore, water source enters the cavity 2 through the water inlet 13, and then passes through the water outlet 10, so that the normal use of the whole pump body can be realized. With the water outlet 10 and the water inlet 13 connected by flanges, the whole pump body can be easily connected to the water outlet pipe. By using the sealing sleeve 11 and the sealing sleeve 2 14 on the outside of the water outlet 10 and the water inlet 13 respectively, the system provides double sealing protection, which helps to reduce the risk of leakage and ensure that the pump body will not overflow or leak during use, thereby improving the overall sealing. The filter sleeve 16 is located inside the water inlet 13, and it is difficult for the debris in the water resources to enter or affect the water inlet 13, which can effectively prevent the water inlet 13 from being blocked during use, thereby affecting normal operation, and the filter sleeve 16 and the water inlet 13 are plug-in installed, which is also convenient for later maintenance and replacement. Through four identical positioning grooves 12, the rapid positioning and installation of the whole pump body can be realized, and the design of the support column 3 also provides a certain protection capability for the cavity 2, thereby preventing the cavity 2 from shaking during use and causing tipping.
