Description

Description: 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. 2. Description of the Related Art In a water storage tank or the like, a water bottom cleaning device is sometimes used for cleaning sediment deposited on the water bottom due to suspended particulates and the like contained in water. The water bottom cleaning device is a power device having a waterproof mechanism containing a control unit and a motor, a traveling device such as a tire and 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 sediment using such a water bottom cleaning device, it was possible to avoid the problem of having to drain the water in the water storage 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,
When the traveling device is moved, water around the traveling device is stirred, and the flow of the stirred water may cause the sediment to diffuse and float. In addition, 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 once at the place where it was 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 underwater cleaning device, and the status of the cleaning and the position of the cleaning device are checked by checking the images from this on a shore monitor. If this is the case, it will be difficult for the underwater camera to grasp the situation in the underwater part. Disperse sediments, especially in water distribution reservoirs.
Floating and making the water turbid is also very problematic in terms of hygiene. Therefore, in order to perform cleaning using the conventional bottom cleaning device, it is necessary to carefully operate the bottom cleaning device at a low speed and perform cleaning so that the turbidity of water due to the diffusion and floating of sediment does not worsen. is there. Therefore, time is spent for cleaning, so that the cleaning efficiency is poor and the operation cost is increased. [0006] The invention according to claim 1 is a power unit having a waterproof mechanism, a traveling unit attached to the power unit, and a power unit and a traveling unit in front of the traveling unit. A water bottom cleaning device, comprising a suction unit provided, a suction hose, and a wiring cable, wherein a traveling device cover that covers the outside of the traveling device so as not to form a gap with the water bottom surface is attached. Make a summary. Therefore, by carrying out the invention of claim 1, since the water around the traveling device is not agitated even when the traveling device is moved, the sediment does not diffuse and float, and the traveling device moves on the sediment. Even when the vehicle rides on the vehicle, the wound-up sediment is sucked from the suction port without leaking out of the traveling device cover, so that there is an effect that water turbidity does not occur. FIG. 1 is a perspective view showing an embodiment of a water bottom cleaning device equipped with a traveling device cover and a cable-integrated hose according to the present invention.
