Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to an emergency centrifugal pump. Background Technology

[0002] With social development, the level of technology has gradually improved, and people's safety awareness and prevention technology have greatly increased. Many factories and large shopping malls have purchased centrifugal pumps for operation, production and safety prevention. Centrifugal pumps refer to pumps that use the centrifugal force generated by the rotation of the impeller to transport liquids. However, nowadays, centrifugal pumps are not easy to transport in emergencies due to their large size. At the same time, the tools used to work with centrifugal pumps are also large, which leads to untimely emergency response. Moreover, in emergency situations, the pumps are not stable enough, which can cause them to malfunction and damage the internal structure. Utility Model Content

[0003] This invention provides an emergency centrifugal pump to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, this utility model provides an emergency centrifugal pump, comprising a centrifugal pump and a movable base. The centrifugal pump is mounted on the base. The movable base has four symmetrically arranged sliding grooves, and two symmetrically arranged cavities connected to the sliding grooves. A movable plate is slidably arranged in each of the two cavities. Two guide rods are symmetrically arranged in the movable base, penetrating the two cavities, and the movable plates are slidably connected to the guide rods. A double-ended threaded rod is rotatably arranged in the movable base between the two guide rods, penetrating the two cavities, and the movable plate is threadedly connected to the double-ended threaded rod. The movable plate moves in opposite directions within the double-ended threaded rod. An inverted L-shaped support frame is slidably arranged in the sliding grooves and is fixedly connected to the movable plate. A threaded adjusting rod is threadedly connected to the support frame, and a pressure plate is installed at the bottom end of the threaded adjusting rod, which presses against the base.

[0005] Preferably, the centrifugal pump base has slots at both ends that match the support frame.

[0006] Preferably, a positioning block is provided at each of the four corners of the movable base, and a threaded support column is threadedly connected to the positioning block, and an abutment block is installed at the bottom end of the threaded support column.

[0007] Preferably, the bottom of the movable base is provided with a sliding groove corresponding to the limiting groove, and the limiting groove is connected to the cavity. The bottom of the movable plate located in the cavity is provided with a limiting block that is slidably connected to the limiting groove.

[0008] Preferably, a drive handle is installed at one end of the double-ended threaded rod.

[0009] The beneficial effects of adopting the above technical solutions are:

[0010] 1. The movable plate is driven to move within the cavity by a double-ended threaded rod, thereby driving the support frame to move and limiting the base of the centrifugal pump from the four corners on both sides. Then, the rotation of the threaded adjusting rod on the support frame causes the pressure plate to press the base, which facilitates the limiting of bases of different sizes, making it easier to match different centrifugal pumps and improving applicability.

[0011] 2. The movable base facilitates the movement of the equipment. The threaded support column adjusts the contact block so that the contact block touches the ground, thereby facilitating the adjustment of the balance of the movable base, adapting to different terrains, ensuring stability, and preventing equipment damage caused by unstable placement.

[0020] like Figure 1-4 In this embodiment, an emergency centrifugal pump includes a centrifugal pump 1 and a movable base 2. The centrifugal pump 1 is mounted on the base 11. The movable base 2 has four symmetrically arranged sliding grooves 21, and two symmetrically arranged cavities 22 connected to the sliding grooves 21 are formed inside the movable base 2. A movable plate 23 is slidably arranged in each of the two cavities 22. Two guide rods 24 are symmetrically arranged inside the movable base 2, penetrating the two cavities 22, and the movable plate 23 is slidably connected to the guide rods 24. A double-ended threaded rod 25 is rotatably disposed between two guide rods 24 and passes through two cavities 22. The movable plate 23 is threadedly connected to the double-ended threaded rod 25. The movable plate 23 moves in opposite directions in the double-ended threaded rod 25. An inverted L-shaped support frame 26 is slidably disposed in the slide groove 21 and is fixedly connected to the movable plate 23. A threaded adjusting rod 27 is threadedly connected to the support frame 26, and a pressure plate 28 is installed at the bottom end of the threaded adjusting rod 27. The pressure plate 28 presses against the base 11.

[0021] Through the above technical solution, different centrifugal pumps 1 are placed on the mobile base 2 according to different scenarios. The two movable plates 23 are moved in the movable cavity 22 by adjusting the double-headed threaded rod 25, thereby driving the support frame 26 to slide in the slide groove 21, so that the support frame 26 abuts against the base 11 of the centrifugal pump 1, thereby limiting the base 11 of the centrifugal pump 1. Then, the threaded adjustment rod 27 drives the pressure plate 28 to press the base 11 of the centrifugal pump 1 from above, thereby limiting the centrifugal pump 1. This makes it easy to stably press centrifugal pumps 1 of different sizes on the mobile base, and at the same time, it is easy to move and improve applicability.

[0022] Preferably, the centrifugal pump 1 has slots 12 at both ends of its base 11 that match the support frame 26.

[0023] Through the above technical solution, the slots 12 at both ends of the lower base 11 of the centrifugal pump 1 match the support frame 26, further improving the stability of the centrifugal pump 1.

[0024] Preferably, a positioning block 3 is provided at each of the four corners of the movable base 2, and a threaded support column 31 is threadedly connected to the positioning block 3, and an abutment block 32 is installed at the bottom end of the threaded support column 31.

[0025] Through the above technical solution, the rotation of the threaded support column 31 in the positioning block 3 adjusts the height, so that the contact block 32 contacts the ground, thereby making it easy to adapt to different terrains, ensuring the stable operation of the centrifugal pump 1, and avoiding damage to the centrifugal pump 1.

[0026] Preferably, the bottom of the movable base 2 is provided with a sliding groove 21 corresponding to the limiting groove 29, and the limiting groove 29 is connected to the cavity 22. The bottom of the movable plate 23 located in the cavity 22 is provided with a limiting block 231 that is slidably connected to the limiting groove 29.

[0027] Through the above technical solution, the bottom limiting groove 29 of the movable base 2 and the bottom limiting block 231 of the movable plate 23 are set to further improve the stability of the movement of the movable plate 23. At the same time, water entering from the sliding groove 29 can be discharged from the movable base 2 to avoid remaining in the movable base 2.

[0028] Preferably, a drive handle 251 is installed at one end of the double-ended threaded rod 25.

[0029] Through the above technical solution, the setting of the drive handle 251 facilitates the driving of the double-headed threaded rod 25, thereby facilitating the adjustment of the support frame 26 and thus facilitating the clamping and positioning of the centrifugal pump 1.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
