Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, specifically an energy-saving, high-flow submersible pump. Background Technology

[0002] Submersible pumps are a common type of water pump used in water. Existing submersible pumps have only one inlet and outlet. Some have the inlet located at the end of the pump, some at the bottom, and some on the side. This means that different submersible pumps need to be selected according to different usage environments, which is very inconvenient. In addition, the rotor blades of the past were straight, resulting in a small water flow rate. Utility Model Content

[0003] This invention provides an energy-saving, high-flow submersible pump that solves the problem that the inlet of existing submersible pumps cannot be adjusted.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving, high-flow submersible pump, comprising a pump casing, a front cover at one end of the pump casing, a water impeller chamber at the end of the pump casing near the front cover, a water outlet on the radial side of the water impeller chamber, a water inlet chamber on the axial side of the water impeller chamber, a conversion port on the inner side of the end of the front cover, a first notch on the radial side of the conversion port, a knob protruding from the end face of the front cover inside the conversion port, the knob being cylindrical and matching the conversion port, a second notch and a baffle on the side wall of the knob, grilles on both sides of the front cover, a bottom water inlet channel communicating with the conversion port at the bottom of the front cover, a drive motor installed inside the pump casing, a rotor located inside the water impeller chamber mounted on the main shaft of the drive motor, and the water inlet of the grille or the bottom water inlet channel can be switched by rotating the knob.

[0005] Preferably, both the first and second notches are rectangular grooves, which have a simple structure and facilitate the control of the water inflow.

[0006] Preferably, the water outlet is tangentially connected to the water blade chamber, resulting in high drainage efficiency.

[0007] Preferably, the rotor is provided with arc-shaped fan blades, which results in high efficiency.

[0008] Preferably, the water tank is snail-shaped, which allows for a large water flow and high efficiency.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] With a simple structure, the pump can switch between side and bottom suction by rotating a knob, achieving integrated side and bottom suction. Users can switch between side and bottom suction according to the application scenario, allowing for control of the submersible pump's inlet to adapt to different operating environments. The rotor with arc-shaped fan blades greatly increases the water flow rate, and the flow rate can be adjusted. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figure 1-6 As shown, this utility model provides an energy-saving, high-flow submersible pump, including a pump casing 1. A front cover 5 is provided at one end of the pump casing 1. A water impeller chamber 3 is provided at the end of the pump casing 1 near the front cover 5. A water outlet 4 is installed on the radial side of the water impeller chamber 3, and a water inlet chamber 8 is provided on the axial side of the water impeller chamber 3. A conversion port 13 is provided on the inner side of the end of the front cover 5. A first notch 11 is provided on the radial side of the conversion port 13. A knob protruding from the end face of the front cover 5 is installed inside the conversion port 13. Part 6, the knob part 6 is cylindrical and matches the conversion port 13. The side wall of the knob part 6 is provided with a second notch 10 and a baffle 30. The front cover 5 is provided with grilles 12 on both sides. The bottom of the front cover 5 is provided with a bottom water inlet channel 7 that communicates with the conversion port 13. The pump housing 1 is equipped with a drive motor 2. The main shaft of the drive motor 2 is equipped with a rotor 9 located in the water blade chamber 3. By rotating the knob part 6, the water inlet of the grille 12 or the bottom water inlet channel 7 can be switched.

[0019] Specifically, the impeller compartment 3 can be connected to one end of the pump housing 1 as a separate component. The front cover 5 can be connected to the impeller compartment 3. The conversion port 13 is integrated with the front cover 5 and docks with the impeller compartment 3. The grille 12 is grille-shaped and occupies most of the area of ​​the two side walls of the front cover 5. The bottom water inlet channel 7 can also be set as a grille to improve the water inlet efficiency.

[0020] When the knob 6 is turned, the first notch 11 and the second notch 10 are misaligned and do not overlap. At the same time, the knob 6 blocks the bottom water inlet groove 7, so that external water cannot enter the conversion port 13.

[0021] When the knob 6 is rotated to the point where the second notch 10 and the first notch 11 partially overlap, the knob 6 will block the bottom water inlet channel 7. At this time, only the water entering through the grille 12 can enter the conversion port 13.

[0022] When the knob 6 is turned to block the first notch 11 and the second notch 10 is connected to the bottom water inlet channel 7, water can be directly introduced into the conversion port 13 through the bottom water inlet channel 7.

[0023] When the knob 6 is rotated to the point where the second notch 10 partially overlaps with the first notch 11, and the second notch 10 is partially connected to the bottom water inlet channel 7, water can simultaneously enter the conversion port 13 through the bottom water inlet channel 7 and the grille 12.

[0024] In this embodiment, both the first notch 11 and the second notch 10 are rectangular grooves, which are simple in structure and facilitate the control of the water inlet. The outlet 4 is tangentially connected to the impeller chamber 3, resulting in high drainage efficiency. The rotor 9 is equipped with arc-shaped fan blades, which are highly efficient. The impeller chamber is snail-shaped, resulting in a large water flow and high efficiency.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
