Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cleaning device for drains, etc., which are installed on the side of roads and have upper openings covered, and which connect manholes.

BACKGROUND OF THE INVENTION Generally, drainage ditches are formed along the sides of paved roads.

Not only rainwater but also dust, mud, soil, etc. from the road are washed away by the rainwater and flow into the side gutter.

Therefore, the dust, mud, soil, etc. accumulate as sludge in the side gutter, obstructing the flow within the side gutter.

By the way, since the upper opening of the above-mentioned side gutter is generally covered with a concrete plate or the like, various methods have been proposed in which the above-mentioned cover is removed during cleaning, a part of the side gutter is exposed, and the inside of the side gutter is cleaned from this opening. has been done.

Problems to be Solved by the Invention The above cleaning is performed, for example, as follows. First, an injection nozzle having front and rear ejection ports is attached to the tip of a high-pressure water supply hose, and this injection nozzle is inserted into the side gutter through an opening in a part of the side gutter.

High-pressure water is supplied from the high-pressure water supply hose to the injection nozzle, and the accumulated sludge is crushed by the forward injection from the injection nozzle, and the accumulated sludge is caused to advance forward by the backward injection.

After the injection nozzle advances to a predetermined position, the hose is wound up and the sludge inside is drawn in by the injection to the rear of the injection nozzle. The cleaning of the inside of the gutter is completed by suctioning the drawn sludge together with water.

In the above method, high-pressure water must be supplied while the injection nozzle is reciprocated, and a high-pressure water supply hose and sludge suction hose must be inserted into the side gutter, resulting in extensive cleaning work. in,
It had become complicated.

Means for Solving the Problems The present invention was devised in view of the above problems, and is a device for cleaning the inside of covered side gutters and tunnels, which is connected to a suction hose extending from a negative pressure suction means. a hollow cylindrical body, a propulsion injection nozzle disposed in the body and connected to a high-pressure water pipe extending from a high-pressure water supply means to inject high-pressure water rearward; It consists of rotary crushing cutters arranged at intervals and a traveling guide roller attached to the outer surface of the body, and the rotary crushing cutter has a smaller diameter than the opening at the tip of the body and is rotatable. a head member; an injection nozzle that is disposed substantially tangentially to the outer peripheral surface of the head member and receives a supply of high-pressure water from the high-pressure water piping; and a wing member that is radially fixed to the head member. This is a self-propelled cleaning device consisting of a cutter attached via a cutter.

Function The self-propelled cleaning device according to the present invention runs in the gutter by the reaction force of high-pressure water jetted backward from the propulsion jet nozzle, and rotates by the high-pressure water jetted from the jet nozzle. The sludge accumulated in the gutter is crushed by a crushing rotary cutter, and the crushed sludge is suctioned and removed from the opening at the tip of the body by a negative pressure suction means.

is connected. Therefore, the injection nozzles 28, 28...
From the communicating pipes 31, 31... to the head member 2.
High-pressure water supplied into the tank 7 is injected. The blade members 29, 29, . . . are set to have a length that allows them to rotate within the side groove A.

The guide rollers 24 are disposed on the upper, lower, left and right sides of the outer peripheral surface of the first half and the second half of the body 21, respectively.

The guide roller 24 is arranged so as to be able to roll in the axial direction of the body 21, and the distance between the upper and lower guide rollers 24, 24, and the distance between the left and right guide rollers 24, 24 are determined by the width of the gutter to be cleaned. Adjust as appropriate depending on the dimensions of.

The operating procedure of the cleaning tool having the above configuration will be explained below.

First, a part of the cover plate (not shown) of the side gutter A is removed, and the cleaning tool 20 is inserted into the side gutter A from there.

Next, the negative pressure suction means is activated, and the high pressure water supply means is activated.

The high-pressure water supplied from the high-pressure water supply means is
The water flows into the circulation pipe 25 through the high-pressure water pipe 11, and further from the circulation pipe 25 to the communication pipe 3.
1, 31, and then into the head member 27.

The high-pressure water that has flowed into the head member 27 is jetted from the jet nozzles 28, 28, . . . in a substantially tangential direction of the head member 27.

Then, the head member 27 rotates in a direction opposite to the direction in which the high-pressure water is jetted due to the reaction force of the high-pressure water jetted from the jet nozzles 28, 28...
Therefore, the wing members 29, 29... and the wing members 29,

Therefore, by rotating the crushing rotary cutter 23, the cutters 30, 30, . . . crush the sludge B deposited in the side gutter A.

The high-pressure water that has flowed into the circulation pipe 25 is injected toward the rear of the cleaning device 20 from the propulsion injection nozzles 22, 22..., and the reaction force of this high-pressure water causes the guide rollers 24, 24... to roll. The cleaning tool 20 moves forward while being guided within the side gutter A by.

The crushed and stirred sludge B is suctioned and removed from the side gutter A along with the water in the side gutter A from the tip of the body 21 via the suction hose 10.

The above operation is performed continuously as the cleaning tool 20 moves forward, and the sludge B is removed from the area through which the cleaning tool 20 passes.

When cleaning of the gutter A in a predetermined section is completed as described above, the suction hose 10 is wound up and the cleaning tool 20 is returned to its original position and taken out from the gutter A.

After that, repeat the above operation to clean the gutter in the desired section.

In addition, although the case where cleaning the inside of a covered side gutter has been described above, the self-propelled cleaning device according to the present invention is not limited to cleaning the above-mentioned side gutter, but can also be used to clean the inside of a hole such as a sewer connecting between manholes. Needless to say, it can also be used in any case.

Effects of the Invention As explained above, the self-propelled cleaning device according to the present invention uses the reaction force of high-pressure water that is injected backward from the propulsion injection nozzle to move inside the gutter, while the self-propelled cleaning device is injected from the injection nozzle. According to the present invention, the sludge accumulated in the gutter is crushed by a crushing rotary cutter rotated by high-pressure water, and the crushed sludge is suctioned and removed from the opening at the tip of the body by a negative pressure suction means. It is possible to provide cleaning equipment that is easy to work with, reliable, and highly practical.
