Dredging device

Technical Field

The invention relates to the technical field of cleaning devices, in particular to a dredging device.

Background

At present, most outdoor swimming areas such as swimming pools in China still adopt a large number of manual cleaning modes to clean, a few automatic cleaning devices in the market mainly depend on cleaning modes such as rolling brush rotation, disc type brushes and electromagnetic oscillation, and swimming pool disinfection reagents mostly adopt chemical substances such as ozone, sodium hypochlorite and chlorine dioxide to disinfect.

The defects of the prior art are obvious, for example, the manual cleaning has high labor cost and low efficiency, and the manual cleaning has certain problems of negligence and carelessness to cause incomplete cleaning and the like; the disinfection of the swimming pool is not thorough, and microorganisms or disinfection byproducts which cannot be disinfected still exist; the existing equipment on the market can realize the automatic cleaning of the swimming pool and the collection of water surface floaters, but the integrated swimming pool cleaning equipment which can clean the water surface and the water of the swimming pool is not available.

For example, chinese patent application No. 202010784649.2, publication No. 2022.02.18 discloses a swimming pool cleaning device, which relates to the field of electric tools, and includes: the air conditioner comprises a machine body, a first air inlet, a second air inlet and an air outlet, wherein the air outlet can be communicated with the first air inlet and the second air inlet; the floating and sinking mechanism is arranged in the machine body and is used for controlling the floating and sinking of the swimming pool cleaning device in water; a thrust generating mechanism provided on the machine body and capable of generating a thrust from the top of the machine body toward the bottom of the machine body; the power generation mechanism is arranged on the machine body and is used for generating power for moving the swimming pool cleaning device in water; and the sundries collecting mechanism is used for collecting the sundries in the first suction inlet and the second suction inlet suction body. This application can realize the comprehensive cleanness to the swimming pool surface of water, bottom and lateral wall face.

The floating and sinking mechanism of the document increases the buoyancy of the cleaning device by increasing the volume of the chamber by driving the partition member to move by the rotating mechanism, however, the floating and sinking mechanism isolates that water outside the cavity body can not enter the cavity body through the isolating piece, when the rotating mechanism drives the isolating piece to move, a gap is inevitably formed between the isolating piece and the wall surface of the cavity, otherwise, the isolating piece cannot move, so that when the isolating piece moves, water outside the cavity body can possibly permeate into the cavity body along the gap between the isolating piece and the wall surface of the cavity body, thereby reducing the air in the cavity body, further influencing the buoyancy of the cavity, finally influencing the floating of the cleaning device, a large amount of water is arranged in the whole dredging device, so that a load is brought to the dredging device, and the floating effect is poor.

(5.4) when the dredging device sinks to the water bottom, the second valve 32 of the water pumping valve 3 is opened, and the first valve 31 is closed.

(5.5) the water pump is started to pump out the water cleaned in the dredging box 22 by the ultrasonic generator through the water outlet 212, and the water pumped out by the water pump forms thrust to push the dredging device to move forwards.

With the structure, when the dredging device needs to be cleaned in water, the dredging device is moved into the water through the moving device 1, the water flows into the dredging box 22 through the water inlet 211 through the water collecting box 20, and after the dredging box 22 is fully stored with water, the water pump is started to pump the water in the dredging box 22 backwards, so that the dredging device is pushed forwards by the thrust of the water; when the direction of the rotation is required, the blade driving component 53 controls the blade 52 of the shutter to swing leftwards or rightwards to change the outlet direction of the water outlet channel 522, so that the rotation of the dredging device is realized, when the dredging device is required to rotate leftwards, the driving motor drives the blade 52 to swing rightwards (as shown by an arrow in fig. 12) of the water outlet, so that the direction of the water outlet channel 522 is changed, the outlet of the water outlet channel 522 is deviated to the left of the water outlet 212, therefore, when water pumped by the water pump passes through the water outlet channel 522, the direction of the water flow is changed through the action of the water outlet channel 522, the water flow is enabled to flow leftwards, and finally, the rear end of the dredging device is swung rightwards through the leftward thrust of the water, so that the left rotation of the dredging device is realized; when the dredging device needs to turn to the right, the driving motor drives the blade to swing to the left (as shown by an arrow in fig. 13).

In-process that the desilting device gos forward, water is constantly through desilting case 22, when water is when through desilting case 22, ultrasonic generator produces the ultrasonic wave and propagates in aqueous, and then clean water, and clean water is taken out outside the desilting device through the water pump, can make the desilting device remove in aqueous from this, also can guarantee that clean hydroenergy flows back to the outside, moreover, the steam generator is simple in structure and effective, and simultaneously, when the desilting device need advance, the second valve 32 of valve 3 that draws water is opened, first valve 31 is closed, make delivery port 212 and desilting case 22 intercommunication, the water pump can begin to draw water from this.

When the dredging device needs to move downwards to the water bottom for cleaning, the second valve 32 of the water pumping valve 3 is closed, the first valve 31 is opened, the water pump is started reversely, water at the water outlet 212 is pumped into the weight box 23, so that the weight box 23 increases the gravity of the weight box 23 due to more and more water, the buoyancy of the weight box 23 is less, the gravity of the dredging device is larger than the buoyancy, and finally the dredging device gradually sinks.

When the dredging device needs to float upwards, the second valve 32 of the water pumping valve 3 is closed, the first valve 31 is opened, the water pump is normally started, water in the weight box 23 is pumped out, therefore, air in the weight box 23 is increased, buoyancy of the weight box 23 is increased, and then buoyancy of the dredging device is increased.
