Groundwater well cleaning device using brush {APPARATUS FOR CLEANING WELL USING BRUSH}

The present invention relates to a groundwater core cleaning device using a brush, and more particularly, to clean the inner wall of the groundwater core well without damage by using a brush and washing water to expand the groundwater passage and groundwater due to the scale or sediment attached to the inner wall of the core The present invention relates to a groundwater cardiac cleaning device using a brush that prevents contamination of groundwater in the heart well so that it is possible to continuously and constantly collect clean and clean groundwater at all times, and simplifies the structure for driving the brush.

Underground water is usually used to digest groundwater below the surface layer and groundwater aquifer underground water is installed in groundwater aquifer. Groundwater is generally pumped into the groundwater core through the fracture joint layer formed in weathered rocks or soft rocks. The groundwater is pumped from the fracture joint layer and the sand or clay components flow into the groundwater core It enters the bottom of the groundwater bed and becomes a slime. In addition, some groundwater deposits may form a slime by accumulating rock dust separated from excavated walls on groundwater. In addition, if long-term groundwater intrusion is maintained, floating substances or foreign substances are entangled in the excavation wall of the groundwater, and thus, the phenomenon of entanglement in the entire area where the water level changes due to the fluctuation of the groundwater level due to operation of the groundwater pump . Especially, in the case of the underground water installed in the road, when the groundwater pump is operated, the groundwater level is lowered and the air for volume compensation is sucked. For this reason, since the automobile soot naturally flows into the groundwater, And black soot accumulates on the surface of the excavation wall to cause clumping. Mosses are formed in the inner well material inserted into the excavation wall or inside of the excavation hole of some ground water, and the separated materials are accumulated on the bottom surface of the groundwater to form slime. Although crickets are extremely abundant, crickets are formed in large quantities, resulting in the formation of slimes due to their bodies, and decayed debris is attached to the walls of the walls to continuously pollute the water quality of groundwater.

These slime and clogged foreign matter all pollute the inside of the underground water, and as a result, the quality of the ground water is altered and polluted, which makes it difficult to maintain the sanitation of the groundwater. In order to prevent this phenomenon, it is necessary to regularly clean the inside of the underground water surface in order to remove the slime of the underground water surface as well as the excavation wall. The present inventors have progressed a number of technologies for the efficient and economical internal cleaning of the groundwater heart well, which is registered patent No. 10-0338257 (patent name: groundwater deep vein cleaning device and cleaning method using liquefied carbon dioxide) and Patent registration No. 10-0714431 (Ground water core cleaning device and method by brush and washing water), Patent registration No. 10-0856784 (Ground water core cleaning device and cleaning method using cooling device and fixed breaker) The system and method to clean the inside of the groundwater wells have been presented, and the achievements of technology development have been achieved, and they are being applied in industrial sites. In addition, another method for cleaning the inside of some groundwater wells is Patent Registration No. 10-0531470 (groundwater cleaning device and its cleaning method through the surface spray and vacuum suction), and also the internal cleaning of the general groundwater wells is a so-called surging construction In this case, many groundwater cores lower the air pipe to supply compressed air to the bottom of the groundwater core, and then inject high-pressure compressed air to discharge the compressed air and groundwater to the ground. In addition to being discharged together, the groundwater excavation walls can be cleaned by the discharged groundwater and compressed air.

However, these conventional methods have the following problems. In other words, the groundwater core cleaning method using liquefied carbonic acid gas has a problem that the expensive liquefied carbonic acid gas injection device must be prepared as well as a high level of technology required for operation, which has a lot of restrictions in actual operation. Groundwater treatment method using compressed pressurized air or high pressure jet water is effective in exposed excavation walls because the groundwater level is below, but the efficiency of compressed high pressure compressed air or high pressure jet water drops rapidly in the water below groundwater level. In addition to the problem, the complexity of the device configuration was inevitable because the driving force had to be secured from the ground to obtain rotational force.

The groundwater cleaning method using a brush that has the highest direct cleaning effect has a high cleaning effect. However, if you want to get the rotational force to rotate the brush inside the groundwater core, the rotational power of the driving motor is synchronized with the cleaning device such as a brush. There was a problem that the characteristics are rotated in the same direction together. In order to rotate the brush, it is inevitable to obtain the rotational force from the ground, so the drilling equipment is put into the field and the fixed rod made of the steel pipe equipped with the brush at the bottom end is extended. Was extended to take the form of a brush attached to the bottom end. Moreover, it is possible to carry out the work in the renovated place due to the equipment input and the installation of the landing rod and the pipe pipe. However, most groundwater wells are installed inside the administrative building, the basement floor of the building, or concrete upper protection workers. Although it was installed in the installation place, it was impossible to insert or install the excavation equipment, so the cleaning using the brush had a limit in its application despite the high effect. Patent application No. 10-2007-, which has the function of maximizing the effect using the brush having high washing effect and preventing the synchronization rotation by using the fixed breaker on the groundwater core wall for washing using the brush without adding the equipment. Developed 0001982 (groundwater core cleaning device and cleaning method using coordination rotation prevention device to apply compressive force to groundwater well wall), but this also requires separate device configuration to operate fixed breaker, especially driving to rotate brush Difficulties in the configuration, operation and maintenance of the motors.
