Detailed Description

According to the technical characteristics of the invention, figure 1 relates to a perspective schematic view of a water bottom cleaning device, the whole device is placed in water, a discharge port structural part (5) of a sewage discharging rod (4) is connected with a pipeline of a shore ship outside a water surface, wherein a suction nozzle structure (1), a linear pump element (2) and a hose (3) are all parallel to the water bottom, when the linear pump element is started, sludge is sucked from the suction nozzle instantly, and after pressurization, the sludge ascends along a through hole in the sewage discharging rod through the hose and is discharged outside. The electric control box (6) supplies power to generate current heat which is dissipated through the surrounding aqueous medium to form a stable working state.

The sludge in front of the suction nozzle is quickly sucked away in the water bottom, and a fluid density difference is generated relative to the water bottom behind the suction nozzle, namely, the front pressure difference and the back pressure difference force the suction nozzle to carry the linear pump element and the related components together to synchronously exceed the suction direction and continuously advance.

If the electric energy of the battery inside the electric control box meets certain underwater sludge cleaning energy, the external power frequency power supply does not need to be accessed, and otherwise, the battery needs to be charged or replaced to meet continuous work.

According to the technical characteristics of the invention, figure 2 relates to a cross section side view display of a water bottom cleaning device, the sections of different sewage discharging rods are adopted according to the water bottoms with different depths of water, and if the water depth is less than the total length of the sewage discharging rods, namely the sum of the lengths of a first section (41) of the sewage discharging rod, a second section (42) of the sewage discharging rod and a third section (43) of the sewage discharging rod, the second section of the sewage discharging rod is cancelled; if the water depth exceeds the total length of the pollution discharge rod, pipe fittings with equal pipe diameters need to be added between the first section of the pollution discharge rod and the second section of the pollution discharge rod or between the second section of the pollution discharge rod and the third section of the pollution discharge rod.

According to the technical characteristics of the invention, as shown in a three-dimensional schematic diagram of a suction nozzle assembly of the underwater intelligent cleaning device in a figure 3 and a cross-sectional schematic diagram of the suction nozzle assembly of the underwater intelligent cleaning device in a figure 4, in the process of sludge adsorption, a permanent magnet structural member (13) and a filter screen (16) are fixedly arranged at the edge of a suction inlet (11) of the suction nozzle assembly, so that underwater iron impurities can be adsorbed in time, or large-head impurities are isolated outside the suction inlet (11), the phenomenon that an outlet (12) is blocked by a sludge suction duct (15) is prevented, and when a large amount of adsorbed iron impurities exist, manual work can be directly carried out at the suction inlet, and the shape of a flat sharp-pointed nozzle (14) with an acute angle is beneficial to reducing resistance and advancing, and firm and blocky objects can be separated.

According to the technical characteristics of the invention, figure 5 relates to a perspective schematic view of a sewage discharging rod of a water bottom cleaning device, and the perspective schematic view shows that if the length and the width of a water area are smaller, a balance wing component (45) on the sewage discharging rod is detached, a grab handle structure component (46) fixed on the sewage discharging rod is manually operated, and a thumb is directly operated on a panel key, so that the water bottom sludge cleaning of the small water area can be completed.

If the water area is large, a balance wing assembly is arranged at the third section of the sewage discharging rod, the underwater weight of the whole cleaning device is lifted by utilizing the buoyancy of the balance wing assembly, so that the suction nozzle assembly and the linear pump element can move forward in contact with the water bottom 0, and the discharge structural member (48) is communicated with a sewage discharging pipeline outside the water area.

According to the technical feature of the invention, fig. 6 is a perspective schematic view showing a handle structure of a submarine cleaning device, and if a water area is large and a handle structural member is detached from a sewage draining rod, an operator can hold a panel button (463) of a handle (462) on a shore ship and realize remote control by butting an infinite remote control circuit (464) with a radio frequency circuit of an electric control box. In order to prevent the young or non-professional in the vicinity from accidentally operating, the child lock button is triggered to lock the panel.

Figure 7 shows a schematic perspective view of a balance wing assembly of a bottom cleaning apparatus according to the present invention, where the installation position of the balance wing assembly is adjusted to meet the requirement of buoyancy contact with the bottom 0 according to the water surface at different depths, and the adjustment disc (455) is rotated by hand to meet the appropriate tightness.

When the balance wing assembly is driven to advance by the continuous pressure difference of the underwater fluid, the width (451) of the balance wing assembly is smaller than the arc length (456), and the balance wing assembly floats on the water surface by a very thin thickness (452), so that the minimum water resistance is realized, and the suction nozzle, the linear pump element and the electric control box are heavy, namely the gravity center is downward, so that the pollution discharge rod cannot be inverted.

According to the technical characteristics of the invention, the figure 8 relates to a block diagram display of an electric working principle of a water bottom cleaning device, when a battery (A1) or a power frequency power supply (A2) is powered on, the power supply is converted into voltages required by various circuits through a power supply management circuit (B), then a CPU single chip circuit (C) is powered on, system self-checking is carried out immediately, and after all input and output circuits are normally self-checked, a CPU is in a standby state.

After the panel key on/off key is triggered, the CPU is started immediately to trigger a signal to a linear pump element driving circuit (D), then different vector current outputs enter the linear pump element from the driving circuit, the suction action is started, the suction nozzle, the linear pump element and the sewage discharging rod move together, after the panel key on/off key is triggered again, the CPU responds to a closing instruction immediately, and the linear pump element stops working.

When the water depth sensor (E1) detects that the water depth exceeds the set depth, the single chip microcomputer CPU immediately outputs a stop instruction until the water depth is recovered to the normal set depth value, and the normal start is recovered.

When the voltage sensor (E2) detects that the voltage exceeds the set voltage or is lower than the set voltage, the single chip microcomputer CPU immediately outputs a stop instruction until the voltage returns to a normal value, and then normal starting is resumed.

When the current sensor (E3) detects that the current exceeds the set current, the single chip microcomputer CPU immediately outputs a stop instruction until the current returns to a normal value, and then normal starting is resumed.

When the remote control circuit of the grab handle transmits signals, the signals are received by the antenna, processed by the radio frequency circuit (F), enter the CPU for analysis, and immediately send out a target instruction, and simultaneously, the signals are fed back to the remote control circuit of the grab handle through the radio frequency circuit and the antenna to receive the current real-time state information.

When the linear pump element works for a long time, the inside of the duct of the whole device needs to be cleaned regularly, the device leaves a water bottom sludge area, clean water is poured out of a discharge structural part of the sewage discharging rod after a cleaning button on the grab handle component is triggered, and automatic cleaning can be realized.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes should fall within the scope of the claims of the present invention.
