JPH03253604A - Cleaning apparatus for inside wall of water way - Google Patents

Abstract

PURPOSE:To safely carry out a work and prevent river or others from being polluted, by removing or sucking to recover pollutant sticked to the inside wall of a water way, a closed conduit, etc., by a cleaning device while transferring a caterpillar type crawler by a remote controller or self-advancing. CONSTITUTION:A cleaning apparatus for the inside wall of a water way is composed of a cleaning apparatus body 3, caterpillar type crawler 4, a cleaning part 6, a rotary supporting member 7, a rotary shaft 8 having common use with a pollutant conduit pipe, etc. And the cleaning part 6 is pressed on the wallface 1 at the rear side while transferring the cleaning apparatus by driving the traveller 4 to remove pollutant on the wall face. And further, the sludge 6 is contained into the cleaning part 6 and sucked from sludge inlet 13 to convey to the outside of a water way or a closed conduit through a duct 9. In this way, it is not necessary for a persons to enter into the water way and the safety is increased and they can work without stopping or weakening water flow.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applied to cleaning the inner walls of waterway chambers or culverts installed in industrial facilities such as power plants and factories, and collecting filth (shellfish, etc.). This invention relates to a cleaning device.

[Conventional technology]

Conventionally, cleaning of the inner walls of waterways or culverts has been carried out by people with special skills, such as divers, when the operations of industrial facilities such as power plants and factories have been suspended or reduced.

[Problem to be solved by the invention]

Conventional cleaning methods such as those described above are dangerous because all work is carried out by people directly entering the waterway or culvert. It also has an impact on industrial activities where it is necessary to stop or reduce the flow of water in canals or culverts to improve operational safety.

[Means to solve the problem]

A self-propelled cleaning device equipped with a tracked running device is used to move through waterways or culverts.

Each part of the cleaning device has a shape with low water resistance so that it will not be swept away even when the flow velocity in the waterway or culvert is high. In addition, inside the culvert, two track-type traveling devices are pressed against the floor and ceiling of the culvert, respectively, to increase the strength to resist the water flow, and the system is installed in the upstream direction of the waterway or culvert. Or run downstream.

The cleaning section that cleans the inner wall is equipped with a mechanism that can change the length of the cleaning section support member depending on the size of the waterway and culvert.
Rotate the cleaning unit to clean the pipe vertically or horizontally. Additionally, in the cleaning section, there is a gold membrane device that collects dirt released from the wall surface, and the collected dirt is transported through a duct to the outside of the waterway pipe or culvert.

[Effect]

Since it is remotely controlled or self-propelled using a track-type traveling device, the cleaning and collection device removes and suctions the dirt adhering to the inner wall of the waterway or culvert.

The filth released from the wall is collected and transported via ducts to treatment facilities on land, so it does not pollute rivers and oceans.

〔Example〕

1 to 4, 1 is the inner wall of the waterway or culvert, 2 is dirt attached to the wall surface, 3 is the main body of the cleaning device, 4 is the track type traveling device, 5 is the power transmission type support member, 6 is a cleaning section, 7 is a rotating support member, 8 is a rotating shaft that also serves as a waste transport pipe, 9 is a waste transport duct, 10 is a telescopic power transmission support member, 11 and 12 are support members for the traveling device, 13 is the filth suction port.

FIG. 1 is a perspective view showing the cleaning device according to the present invention running in a waterway or a culvert. Power such as electricity is transmitted to the cleaning device through attached cables, etc. Using the transmitted power, the built-in drive device 3 generates driving force, and the supporting members 5, 1
The cleaning device moves by transmitting driving force to the track type traveling device 4 through the roller 0 and fully operating the traveling device 4. The support member 5 supports the traveling device 4 and also supports the traveling device 4.
This is a power transmission type support member that transmits driving force to. The support member 10 is a telescopic power transmission type support member that supports the support member 5, transmits driving force to the support member 5, and can change the vertical position of the traveling device 4 according to the ceiling height in the culvert. It is.

The support member 11 has the same function as the support member 5, and the support member 12 has the same function as the support member 10, but does not transmit power and performs only support.

The cleaning unit 6 is a device for removing dirt adhering to the wall surface, and as shown in Fig. 3, the front side in the direction of movement is lifted off the wall surface and the rear side in the direction of movement is pressed against the wall surface to remove dirt from the wall surface. It is separated from the wall surface and wrapped inside the cleaning part 6 to prevent it from escaping to the outside. In this state, the filth is sucked through the filth suction port 13 and transported to the outside of the waterway or culvert via the filth transport duct 9, thereby preventing contamination inside the waterway or culvert. The length of the damp cleaning section 6 can be adjusted according to the height or width of the wall surface. The rotation support member 7 supports the cleaning section 6 and can adjust its length according to the height or width of the wall surface so as to press the cleaning section 6 against the wall surface. The rotating shaft 8 supports the cleaning section 6 and the rotation support member 7, and rotates to enable the cleaning section 6 to clean the wall surface in the horizontal direction and the vertical direction (ceiling, floor).

Figures 2 and 3 show the cleaning status of the wall surface, and Figure 4 shows the cleaning status of the wall surface.
Shows the cleaning status of the ceiling and floor.

〔Effect of the invention〕

The waterway inner wall cleaning device according to the present invention includes a track-type traveling device that runs inside a waterway pipe or a culvert, a cleaning and recovery device that cleans the inner wall and collects the waste released from the inner wall, and a cleaning device that moves the collected waste outside the waterway. The installation of ducts and metal fittings for transporting filth has the following effects.

When cleaning the inner walls of waterways or culverts during industrial activities at power plants and factories, it is extremely dangerous and difficult for humans to do the work directly, as in the past, due to the presence of water currents. . In addition, filth released from the walls during cleaning work may flow downstream and contaminate the river cabinet or the entire ocean.

According to the present invention, waterways or culverts can be cleaned by remote control, so there is no danger during the work. In addition, since the dirt released from the wall surface during work is collected by suction,
River cabinets can prevent pollution of the ocean.
