[0052] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0053] Please refer to Figures 1 to 11 As shown, an embodiment of this utility model provides an underwater electric sludge suction machine, including: an upper housing 1, a base 2, a suction unit 7, and a filter screen 6 for filtering sewage entering the base 2, wherein:

[0054] Both ends of the upper housing 1 are provided with water outlets 101; the base 2 is equipped with a walking component, and both ends of the bottom of the base 2 are provided with water inlets 201.

[0055] The suction unit 7 is fixedly installed inside the upper housing 1. The suction unit 7 includes a first housing 701. Both ends of the first housing 701 are fixedly installed with drive motors. The shafts of the two drive motors rotate through the first housing 701 and are fixedly installed with fan blades 702. The water outlet direction of the two fan blades 702 is towards the corresponding water outlet 101. The filter screen 6 is set between the upper housing 1 and the base 2.

[0056] When the underwater electric vacuum cleaner is working, the two drive motors inside the first housing 701 of the suction unit 7 drive the corresponding fan blades 702 to rotate. Since the water outlet direction of the fan blades 702 is towards the outlet 101, a negative pressure is formed inside the upper housing 1 and the base 2. Under the action of negative pressure, sewage enters the interior of the base 2 from the inlets 201 at both ends of the bottom, and then passes through the filter screen 6 to remove impurities. The filtered water is then drawn away by the suction unit 7 and discharged from the outlet 101. During use, it is possible to select whether to use one drive motor or both simultaneously, and the walking component will move the entire device underwater to clean different areas. The upper housing 1 is detachably connected to the base 2 by the locking piece 3, which facilitates the inspection and cleaning of the internal components.

[0057] In this embodiment, the top of the base 2 is provided with an assembly groove 203, the filter screen 6 is disposed in the assembly groove 203, and the lower end of the upper shell 1 presses against the top of the filter screen 6.

[0058] The mounting groove 203 on the top of the base 2 provides an installation position for the filter screen 6, which can position the filter screen 6 and prevent it from shifting during equipment operation. The lower end of the upper housing 1 presses against the top of the filter screen 6, which can firmly fix the filter screen 6 in the mounting groove 203, and also form a good seal between the filter screen 6 and the base 2 and the upper housing 1, preventing unfiltered sewage from directly entering the interior of the upper housing 1 through gaps, thus ensuring the filtration effect.

[0059] In this embodiment, the locking member 3 includes a plate 301. Two plates 301 are provided. The two plates 301 are respectively fixed on opposite sides of the upper housing 1. A locking plate 302 is formed at the bottom of the plate 301. A locking head 303 is formed at the lower inner end of the locking plate 302. Limiting protrusions 205 are formed on opposite sides of the base 2. The locking head 303 can be locked on the limiting protrusions 205.

[0060] When connecting the upper housing 1 to the base 2, place the upper housing 1 on the base 2, aligning the latches 303 at the lower inner ends of the latch plates 302 at the bottom of the two plates 301 with the limiting protrusions 205 on both sides of the base 2. By pressing the upper housing 1, the latches 303 will lock onto the limiting protrusions 205, thus achieving a fixed connection between the upper housing 1 and the base 2. When disassembly is required, pry the latch plates 302 outward to disengage the latches 303 from the limiting protrusions 205, allowing the upper housing 1 to separate from the base 2. The operation is simple and convenient, achieving a detachable connection between the two.

[0061] In this embodiment, the base 2 is provided with a backflow preventer 202 to prevent impurities trapped inside the base 2 from being discharged from the water inlet 201. The lower end of the backflow preventer 202 is hinged to the inner bottom of the base 2, and the upper end of the backflow preventer 202 can cover the water inlet 201.

[0062] When the equipment is performing sewage suction, sewage enters the base 2 through the inlet 201. The water flow pushes the check baffle 202 upward, opening the inlet 201 and ensuring smooth sewage entry. When the equipment stops working or water flows in the opposite direction, the upper end of the check baffle 202 rotates downward under its own weight and the pressure of the possible reverse water flow, covering the inlet 201. This prevents impurities trapped inside the base 2 from flowing back out through the inlet 201, ensuring that impurities are effectively collected.

[0063] In this embodiment, four sets of walking components are provided. The four sets of walking components are respectively installed at the four corners of the base 2. Each of the four sets of walking components includes a roller 4. The roller 4 is rotatably installed on the base 2. A walking motor for driving the roller 4 to rotate is fixedly installed inside the base 2.

[0064] When the four sets of walking components at the four corners of the base 2 are working, the walking motors drive the corresponding rollers 4 to rotate. By controlling the speed and direction of the four walking motors, various movement actions such as forward, backward, and turning can be achieved, enabling the equipment to perform cleaning operations at different underwater locations, improving the cleaning range and flexibility. The four sets of walking components also ensure the stability of the equipment when moving underwater.

[0065] In this embodiment, protective grids 703 for protecting the fan blades 702 are fixedly installed at both ends of the first housing 701. The protective grids 703 are fixedly installed at both ends of the first housing 701, located on the outside of the fan blades 702, and provide effective protection for the fan blades 702.

[0066] In this embodiment, a connecting ear 704 is fixedly installed at the end of the protective grid 703 away from the first housing 701, and the connecting ear 704 is fixedly connected to the inner top of the upper housing 1 by bolts.

[0067] The end of the protective grid 703 away from the first housing 701 is fixedly connected to the inner top of the upper housing 1 by connecting lugs 704 and bolts. This connection method not only fixes the protective grid 703 to the first housing 701, but also forms a solid connection with the upper housing 1, which further enhances the installation stability of the protective grid 703, making it less likely to loosen or fall off under the conditions of water flow impact and equipment vibration, and ensuring the continuous and reliable protection effect on the fan blade 702.

[0068] In this embodiment, a second housing 705 is fixedly installed on the top of the first housing 701, and a control circuit board is fixedly installed inside the second housing 705. The walking motor and the drive motor are both electrically connected to the control circuit board.

[0069] The control circuit board inside the second housing 705 is the core of the entire device's control system, and it is electrically connected to the travel motor and drive motor. The control circuit board can receive relevant control signals and control the speed and direction of the travel motor according to a preset program or external commands to achieve the movement control of the device; it can also control the start and stop of the corresponding drive motor as needed.

[0070] In this embodiment, a rechargeable battery is fixedly installed inside the second housing 705, and the battery is electrically connected to the control circuit board.

[0071] The rechargeable battery inside the second housing 705 provides power to the entire device. Electrically connected to the control circuit board, the battery supplies power to the board, which then distributes it to various electrical components such as the walking motor and drive motor, ensuring their normal operation. When the battery is low, it can be recharged, allowing the device to continue underwater cleaning operations, eliminating real-time dependence on external power and improving the device's operational flexibility.

[0072] In this embodiment, a conductive male connector 204 and a conductive female connector 5 are also included. The conductive female connector 5 is fixedly installed on one side of the outer wall of the upper housing 1 and is located on the inner side of the plate 301. The conductive male connector 204 is fixedly installed on one side of the outer wall of the base 2.

[0073] The conductive male connector 204 includes a first insulating base 2041, an insulating protrusion 2043 is formed on the top of the first insulating base 2041, a conductive pin 2042 is fixedly installed on the insulating protrusion 2043, the conductive pin 2042 is electrically connected to the walking motor, and a first step 2044 is provided at the upper end of the first insulating base 2041.

[0074] The conductive female connector 5 includes a second insulating base 501. A first sealing groove 502 is provided at the bottom of the second insulating base 501, and a second sealing groove 503 is provided at the top of the second insulating base 501. A conductive sleeve 504 is fixedly installed inside the second sealing groove 503, and the conductive sleeve 504 is electrically connected to the control circuit board.

[0075] During installation, the second insulating base 501 is fitted onto the first insulating base 2041, the first sealing groove 502 is pressed onto the first step 2044, the second sealing groove 503 is fitted onto the insulating protrusion 2043, and the conductive pin 2042 is inserted into the conductive sleeve 504.

[0076] When the housing 1 and base 2 are installed, the second insulating base 501 is fitted onto the first insulating base 2041, and the conductive pins 2042 of the conductive male connector 204 are inserted into the conductive sleeve 504 of the conductive female connector 5, thereby realizing the electrical connection between the walking motor and the control circuit board, enabling the control circuit board to control the walking motor. Simultaneously, the first sealing groove 502 presses against the first step 2044, and the second sealing groove 503 is fitted onto the insulating protrusion 2043. These two sealing structures effectively prevent water from entering the conductive connection parts, ensuring stable and reliable conductivity and avoiding faults such as short circuits.

[0077] It should be noted that in this embodiment, both the second insulating base 501 and the first insulating base 2041 are made of elastic insulating rubber. During installation, the first sealing groove 502 and the first step 2044 are in an interference fit, and the second sealing groove 503 and the insulating protrusion 2043 are also in an interference fit.
