[0034] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0035] like Figure 1-2 As shown, a secondary sedimentation tank floating mud cleaning device includes:

[0036] buoy 1;

[0037] The sludge pump 2 is installed at one end of the buoy 1. The sludge pump 2 is provided with a sludge extraction port and a sludge discharge port. The sludge extraction port of the sludge pump 2 is suitable for extracting floating sludge from the secondary sedimentation tank.

[0038] A propulsion device is installed at the other end and both sides of the buoy 1, and is suitable for driving the buoy 1 to move on the secondary sedimentation tank;

[0039] A sewage pipe 3, one end of which is connected to the sludge outlet of the sludge pump 2, and the other end is connected to the sludge collecting tank;

[0040] a remote control device, the remote control device being electrically connected to the propulsion device and being adapted to receive operations and control the movement of the propulsion device;

[0041] The cable includes a power cord, one end of which is connected to the sludge pump 2 and the propulsion device respectively, and the other end is connected to an external power supply.

[0042] In this embodiment, if Figure 1-2 As shown, first place the float 1 in the secondary sedimentation tank, connect one end of the sewage pipe 3 to the sludge pump 2, and extend the other end into the sludge collecting tank. Subsequently, connect the sludge pump 2 and the propulsion device to an external power source, use a remote control device to control the propulsion device, and drive the float 1 to move in the secondary sedimentation tank. The sludge pump 2 at one end of the float 1 continuously extracts the floating sludge during the movement, thereby achieving efficient cleaning of the floating sludge in the secondary sedimentation tank. The entire process significantly improves the floating sludge treatment efficiency. In some embodiments, the cable also includes a traction line, which can be used to drive the float 1 to move by pulling the traction line.

[0043] Specifically, the remote control device may have the following structure:

[0044] Control terminal;

[0045] a controller connected to the propulsion device;

[0046] a communication module, the communication module being communicatively connected with the controller and the control terminal;

[0047] The control terminal is adapted to transmit the input control instruction to the controller via the communication module;

[0048] The controller is suitable for controlling the action of the propulsion device according to corresponding control instructions.

[0049] In this embodiment, the remote control device inputs control commands via a control terminal, which are then transmitted to the controller via the communication module. Ultimately, the controller controls the propulsion device based on the received commands, thus achieving wireless remote control of the entire floating mud removal device. The controller is well known to those skilled in the art, and its specific structure is not described in detail here. The control terminal can be a common remote control, a mobile phone, or a tablet. The controller can be powered by either its own batteries or a power cord.

[0050] Specifically, the communication module includes a wireless communication module.

[0051] In this embodiment, the wireless communication module may be a WiFi wireless module or a 2.4g communication module. The WiFi wireless module or the 2.4g communication module may be specifically an existing technology and will not be described in detail in this embodiment.

[0052] Specifically, in some embodiments, the cable further comprises a communication cable;

[0053] The communication module includes a wired communication module, and the wired communication module is suitable for communicating through the communication cable.

[0054] In this embodiment, the remote control device can also utilize a wired communication module, enabling wired data transmission with the control terminal via a communication cable. Advantages of wired communication include long communication distance, strong anti-interference capabilities, and high reliability. The communication cable requires a sheath material with certain waterproof and corrosion resistance. During use, both the wired and wireless communication modules can coexist, allowing the appropriate control method to be selected based on needs.

[0055] Specifically, such as Figure 1-2 As shown, the secondary sedimentation tank floating mud cleaning device further includes a plurality of floats 4 , which are fixed on the sewage pipe 3 .

[0056] In this embodiment, if Figure 1-2 As shown, multiple floats 4 are fixed to the sewage pipe 3 to increase its buoyancy on the water surface, preventing it from being completely submerged in the secondary sedimentation tank and affecting the discharge efficiency of the floating sludge. When the sludge pump 2 is operating, it extracts floating sludge through the sludge extraction port and then discharges it into the sewage pipe 3 through the sludge outlet. Multiple floats 4 are fixed to the sewage pipe 3 to allow it to float on the water surface, keeping the outlet of the sewage pipe 3 above the water surface, thereby facilitating the smooth discharge of the floating sludge into the sludge collection tank. Cables can also be connected to the floats 4.

[0057] Specifically, such as Figure 1-2 As shown, the propulsion device can be structured as follows:

[0058] Main propeller 51, which is installed at the other end of the buoy 1;

[0059] A pair of steering thrusters 52 is installed on both sides of the buoy 1 respectively.

[0060] In this embodiment, if Figure 1-2 As shown, a main propeller 51 is mounted at one end of the buoy 1, providing overall forward propulsion, enabling the buoy 1 to move forward in the secondary sedimentation tank. A pair of steering propellers 52 are mounted on either side of the buoy 1. The difference in thrust from the two steering propellers 52 generates a leftward or rightward steering torque, thereby adjusting the heading of the buoy 1. The main propeller 51 and the steering propeller 52 can be electric propellers, which generate thrust by rotating the propellers through power.

[0061] Specifically, such as Figure 1-2 As shown, the buoy 1 is further provided with a pair of wing plates, which are respectively installed on both sides of the bottom of the buoy 1.

[0062] In this embodiment, if Figure 1-2As shown, the pair of wing panels are designed to increase the stability and rollover resistance of the buoy 1 in the water. When the buoy 1 is traveling in the secondary sedimentation tank, the power of the propulsion system and the impact of the water flow in the secondary sedimentation tank may cause the buoy 1 to sway or tilt. The wing panels installed on both sides increase the buoyancy support area of ​​the buoy 1, improve its stability on the horizontal plane, and reduce the risk of tilting and rolling.

[0063] Specifically, such as Figure 1-2 As shown, the secondary sedimentation tank floating mud cleaning device also includes a counterweight block, which is detachably mounted on the other end of the buoy 1.

[0064] In this embodiment, if Figure 1-2 As shown, the counterweight is used to adjust the center of gravity and overall stability of the buoy 1. By adding a counterweight to one end of the buoy 1, the center of gravity of the buoy 1 can be lowered, lowering the center of gravity position and improving the stability of the buoy 1 on the water surface. The counterweight can be made of metal and, together with the sludge pump 2, creates a reasonable weight distribution at both ends of the buoy 1 to prevent excessive tilt.

[0065] Specifically, such as Figure 1-2 As shown, the secondary sedimentation tank floating mud cleaning device also includes a mud inlet guide cover 6, which is a disc structure with a larger upper part and a smaller lower part. A through hole is opened at the lower end of the mud inlet guide cover, and the through hole is connected to the mud extraction port of the sludge pump 2.

[0066] In this embodiment, if Figure 1-2 As shown, the mud inlet guide shroud 6 guides the floating mud toward the sludge extraction port of the sludge pump 2, improving the efficiency of sludge extraction. As the floating mud removal device travels through the secondary sedimentation tank, the disc structure (larger at the top and smaller at the bottom) guides and concentrates the surrounding floating mud into the through-hole below, where it is then drawn in and discharged by the sludge pump 2. This design significantly improves sludge collection efficiency.

[0067] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
