Description

Technical Field

[0001] This utility model relates to the field of centrifugal pumps, and in particular to a centrifugal pump with protective functions. Background Technology

[0002] In industrial production, municipal water supply, agricultural irrigation and other fields, centrifugal pumps are the core equipment for fluid transportation. Their operational stability, heat dissipation effect, protection capability and working efficiency directly affect the operating efficiency and maintenance cost of the entire system.

[0003] Traditional centrifugal pumps typically have exposed or poorly protected motors and pump bodies, lacking dedicated protective structures for the motor's sides. During equipment handling, idle storage, or use in harsh conditions (such as construction sites or chemical workshops), external debris, dust accumulation, or liquid splashes can easily cause deformation and damage to the motor casing.

[0004] Therefore, it is necessary to propose a centrifugal pump with protective functions to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal pump with protective functions to address the problem that traditional centrifugal pumps often have exposed or simply designed protective structures for the motor and pump body, lacking a dedicated protective structure for the side of the motor. During equipment handling, idle storage, or use under harsh conditions, external debris, dust accumulation, or liquid splashes can easily cause deformation and damage to the motor casing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a centrifugal pump with protective function, comprising a centrifugal pump body and a motor connected to one side of the centrifugal pump body, a support leg fixed at the bottom of the motor, a fixed seat fixed on both sides of the motor, an arc-shaped protective plate rotatably connected in each of the two fixed seats, a support block fixed on the side of the two arc-shaped protective plates away from each other, and an anti-slip pad provided on the side of the support block away from the centrifugal pump body;

[0007] The arc of the arc-shaped protective plate matches the arc of the outer side of the motor. Air outlet slots are opened on opposite sides of the two arc-shaped protective plates, and heat dissipation fins are provided on the outer side of the motor.

[0008] Preferably, a cooling fan is fixed to each of the two arc-shaped protective plates on one side away from each other. The arc-shaped protective plates have cavities inside, and the air outlet and air outlet slot of the cooling fan are connected to the corresponding cavity.

[0009] Preferably, a limiting bolt is threadedly connected to one side of the fixing seat, and one end of the limiting bolt is pressed against the side of the arc-shaped protective plate.

[0010] Preferably, a first connection port is provided on one side of the centrifugal pump body, and a second connection port is connected to the top of the centrifugal pump body.

[0011] Preferably, a support frame is fixed to the outside of the centrifugal pump body.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. The arc-shaped protective plate is attached to the outside of the motor when the equipment is not in operation. It can effectively block external impacts, reduce the risk of failure when the equipment is idle or being moved, and at the same time, it can block the corrosion of the external environment and protect the outside of the motor and the heat sink fins.

[0014] 2. When the motor starts, the arc-shaped protective plate can be rotated open and supported on the ground by the support block and anti-slip pad, which improves the overall structural stability of the device and reduces the shaking and displacement caused by vibration during the operation of the centrifugal pump. At the same time, after the arc-shaped protective plate is opened, the air force generated by the cooling fan can be tilted and blown onto the motor and the cooling fins to complete the heat dissipation work.

[0019] This utility model provides, for example Figures 1-3 The centrifugal pump shown includes a centrifugal pump body 1 and a motor 2 connected to one side of the centrifugal pump body 1. A support leg 3 is fixed to the bottom of the motor 2, and a support frame 14 is fixed to the outside of the centrifugal pump body 1. The support frame 14 and the support leg 3 provide support.

[0020] Both sides of the motor 2 are fixed with mounting bases 4. Arc-shaped protective plates 5 are rotatably connected inside the two mounting bases 4. Support blocks 6 are fixed on the side of the two arc-shaped protective plates 5 that are far away from each other. Anti-slip pads 10 are provided on the side of the support blocks 6 that are far away from the centrifugal pump body 1.

[0021] The arc of the arc-shaped protective plate 5 matches the arc of the outer side of the motor 2, and air outlet slots 9 are opened on opposite sides of the two arc-shaped protective plates 5. Before the centrifugal pump body 1 is working, the two arc-shaped protective plates 5 are set against the outer side of the centrifugal pump body 1 to protect the side of the motor 2 and prevent external impact from damaging the motor 2. When the motor 2 needs to be started, the two arc-shaped protective plates 5 can be rotated open, and the bottom end of the support block 6 can be brought into contact with the ground to complete the support, increase the support area between the motor 2 and the ground, and enhance the overall stability.

[0022] Heat dissipation fins 13 are provided on the outside of the motor 2. The heat dissipation fins 13 are evenly distributed along the circumference of the motor 2. The heat dissipation fins 13 are made of aluminum alloy. The high thermal conductivity of the metal is used to quickly conduct the heat generated by the motor 2 during operation, in conjunction with the subsequent active heat dissipation structure.

[0023] Two arc-shaped protective plates 5 are each fixed with a cooling fan 7 on one side away from each other. The arc-shaped protective plates 5 have cavities inside, and the air outlets and air ducts 9 of the cooling fans 7 are connected to the corresponding cavities. A built-in rechargeable power supply can be installed inside the arc-shaped protective plates 5 and connected to the cooling fans 7. An external power source can be connected to the cooling fans 7 via an electrical wire to provide power.

[0024] Furthermore, when the two arc-shaped protective plates 5 are rotated and opened, the cooling fan 7 is started. The air generated by the cooling fan 7 is discharged from the air outlet 9. The air can be precisely blown to the side of the motor 2 and the heat dissipation fins 13, accelerating the air flow on the surface of the motor 2 and quickly carrying away the heat generated by the motor 2 during operation.

[0025] One side of the fixed base 4 is threaded with a limiting bolt 8, one end of which is pressed against the side of the arc-shaped protective plate 5. When the arc-shaped protective plate 5 is adjusted to the designated position (fitting against the protective or support opening state), tighten the limiting bolt 8, one end of which can be pressed against the side of the arc-shaped protective plate 5. The position of the arc-shaped protective plate 5 is fixed by friction, preventing the arc-shaped protective plate 5 from rotating on its own due to vibration during equipment operation. This ensures the stable performance of the protective or support functions. Moreover, the bolt-type fixing structure is easy to operate and can be adjusted without additional tools.

[0026] The centrifugal pump body 1 has a first connection port 11 on the side away from the motor 2, and a second connection port 12 is connected to the top of the centrifugal pump body 1. The first connection port 11 and the second connection port 12 are the water inlet and the water outlet, respectively. Both are used to connect with external fluid transportation pipelines (such as water pipes, industrial fluid pipelines, etc.) to make the external pipelines connected to the flow channels inside the centrifugal pump body 1. Since this is the basic structure of the centrifugal pump body 1, it will not be described in detail.
