Abstract

PROBLEM TO BE SOLVED: To enhance cleaning efficiency by preventing troubles of being entwined and damaged of a wired cable without beclouding water by soaring deposits by a running device of a bottom cleaning device. SOLUTION: The water is prevented from being beclouded by attaching a cover to the running device so that a gap is not formed between the bottom surface of the water and the outside of the running device of the bottom cleaning device to isolate the running device from the vicinity of the bottom cleaning device. The troubles of the wired cable are prevented by inserting the wired cable into the inside of a sucking hose to make it into a cable-integrated hose. As a result, the cleaning efficiency can be enhanced since the operation becomes easier and high speed traveling cleaning becomes possible.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water bottom cleaning device for suction-cleaning deposits on an internal water bottom surface of a water storage tank or the like.

[0002]

2. Description of the Related Art In a water storage tank or the like, a water bottom cleaning device may be used for cleaning sediments that have settled on the water bottom due to settling of suspended particulates contained in water. The water bottom cleaning device is a power device having a waterproof mechanism including a control unit and a motor, a traveling device such as a tire or a caterpillar driven by the power device, and connected to the power device to transmit operation signals and supply electricity. , A suction unit for performing suction cleaning, and a suction hose. Conventionally,
The traveling device of the water bottom cleaning device was provided on both sides of the power unit, and the whole or most of the traveling device was exposed to the outside. In addition, the wiring cable and the suction hose were separately connected to a water bottom cleaning device. By cleaning the sediment using such a water bottom cleaning device, it was possible to avoid the problem of having to drain the water in the water tank, and to reduce the labor required for manual cleaning.

[0003]

However, when the traveling device is exposed as in the conventional water bottom cleaning device,
By moving the traveling device, water around the traveling device is stirred, and the flow of the stirred water may cause the sediment to diffuse and float. Further, when the traveling device rides on the sediment, the traveling device directly rolls up the sediment, so that the sediment may be diffused and floated over a wide range of water. When cleaning is performed using such a water bottom cleaning device, the sediment that has diffused and floated at the place where it was once cleaned will settle again, so it is necessary to completely remove the sediment with one cleaning. No, the same area needs to be cleaned several times. Usually, the underwater camera is installed in the water bottom cleaning device, and the status of the cleaning and the position of the cleaning device are checked by checking the image from this on a shore monitor. If this is the case, it will be difficult to grasp the situation in the underwater area using the underwater camera. Disperse sediment, especially in water distribution reservoirs.
Floating and turbidity of water is very problematic in terms of hygiene. Therefore, in order to perform cleaning using a conventional bottom cleaning device, it is necessary to carefully operate the bottom cleaning device at a low speed and perform cleaning so as not to worsen the turbidity of water due to diffusion and floating of sediments. is there. Therefore, time is spent for cleaning, so that the cleaning efficiency is poor and the operation cost is increased.

In a state where the suction hose and the wiring cable are separately connected to the water bottom cleaning device as in the conventional water bottom cleaning device, the wiring cable is entangled with structures such as pipes in the water storage tank and valves and ramps. In this case, not only does the running of the water bottom cleaning device be hindered, but also the wiring cable itself may be damaged. Furthermore, when the wiring cable entangled with the structure does not come off or the wiring cable is broken, the water bottom cleaning device may not be able to run and may not be collected. In order to eliminate troubles caused by such cables,
It is necessary to operate the water bottom cleaning device so as to largely avoid the structure, and the operation is difficult, and it is not possible to completely clean the details.

The present invention has been made to solve the above problems, and has as its object to prevent water from becoming turbid, prevent troubles caused by cables, and improve cleaning efficiency.

According to the first aspect of the present invention, since the water bottom cleaning device can clean the sediment without rolling up and spreading and floating the sediment, unlike the conventional water bottom cleaning device, the sediment is collected by one cleaning. Objects can be completely removed, and cleaning efficiency can be dramatically improved. Further, it is easy to grasp the situation of the underwater part by the underwater camera. In particular, there is no problem regarding sanitation in the distribution reservoir for water supply. Furthermore, the skirt completely covers the gap between the body casing and the traveling device cover and the water bottom, increasing the internal negative pressure effect when sucking sediments. As a result, the deposits can be reliably removed, and the running property is stabilized, so that it is difficult to fall. Therefore, when the water bottom is cleaned using the present invention, the running speed of the water bottom cleaning device can be increased, the cleaning efficiency is dramatically improved, the cleaning time is reduced, and the cleaning cost can be reduced.

According to the second aspect of the present invention, since the wiring cable is protected by the suction hose, the wiring cable does not become entangled with the piping, the valve, the ramp or the like in the water storage tank. It does not hinder the running of the device or damage the distribution cable itself. In addition, the connecting means of the cable-integrated hose is connected 36
The adoption of the swivel type joint and the slip ring that rotates 0 degrees increases the freedom of rotation of the water bottom cleaning device. Therefore, when the water bottom is cleaned using the present invention, the operation is easy, and it is possible to clean the details around the structure. Furthermore, the cable-integrated hose of the present invention is easy to handle and easy to store because the suction hose and the wiring cable are integrated.
