Description

SYSTEM FOR INSTALLING EQUIPMENT FOR LOWERING GROUNDWATER LEVELS, INSTALLED ON A WHEELED BASE FIELD OF THE INVENTION

[0001] The present invention relates to a mobile system that facilitates the safe installation of equipment in deep tubular wells to allow the removal of underground fluids; in other words, a system for lowering the groundwater level, installed on a wheeled base to facilitate the movement of the system. FUNDAMENTALS OF THE INVENTION

[0002] In various areas of industry, especially mining and oil exploration, the removal of underground fluids is commonly necessary to lower the groundwater level or to extract hydrocarbons from wells.

[0003] In these operations, in a very summarized way, pipes are usually inserted into the region where fluid removal is desired, so that the fluid is removed with the aid of suction pumps positioned at the bottom of the deep tubular well and, in some situations, one more installed on the surface.

[0004] In a deep tubular well, a suction pump, riser pipes, electrical cables, a level sensor, and various other equipment are used, requiring human operators, consuming a great deal of physical effort, many hours of skilled labor, and posing risks of personal accidents during each installation and dismantling.

[0005] In addition, this equipment must be removed from the deep tubular well and reinstalled several times, which greatly increases the costs of this type of operation and the risks associated with the activity.

[0006] Thus, a system for installing equipment inside deep tubular wells that lowers the groundwater level, which at least partially speeds up this process, could generate significant savings and safety for the industry. In this sense, some prior art documents propose partial solutions to this problem.

[0023] Figure 1 illustrates a view of an optional embodiment of the equipment installation system used for lowering the groundwater level through wells. Deep tubular wells. Here we see a semi-automatic mobile machine, which can be operated remotely, mounted on a wheeled base to install equipment used in lowering the groundwater level through deep tubular wells.

[0024] More broadly, the invention relates to a system for installing equipment for lowering the level of groundwater, installed on a wheeled base 1, comprising: a telescopic arm 6 and an articulated crane 5 for lifting operations adapted to support, guide and position, before and after operation; an assembly consisting of a hose, electric cable and motor pump; an electric power generating device 9 adapted to provide electrical power to all elements of the system; and at least one drive reel 2 with hose mounted on the wheeled base 1 for storing a hose and electric cable assembly.

[0025] It is worth noting that the wheeled base 1 can be a body attachable to a road truck, as illustrated in Figure 1. Thus, the transport of the entire assembly can be done easily and quickly. However, it should be emphasized that the wheeled base 1 can have other configurations without departing from the scope of the present invention.

[0026] In addition, the system of the present invention further comprises: an oxy-fuel cutting kit 4 installed on the wheeled base 1; and a storage cabinet 3 for tooling and lifting accessories.

[0027] The tools in question may include, but are not limited to, lifting clamps, winding clamps, straps, portable screwdrivers, wrenches, and welding machines. Storage cabinet 3 is fixed to the truck, in an easily accessible location, and has... A dedicated key for locking tools increases security against equipment theft.

[0028] It is also foreseen that the telescopic arm 6 may optionally comprise a load cell adapted to measure the tensile force exerted by the assembly consisting of hose, electric cable and motor pump.

[0029] In this configuration, the telescopic arm 6 can also include means for remote operation. This allows the operator to remain in a safe location during operation, reducing the risk of accidents.

[0030] The articulated crane 5 may also include outriggers. 7 front and rear supports are installed to stabilize and level the assembly during lifting and / or winding of the hose, electrical cable, and motor pump assembly. Like the telescopic arm 6, the articulated crane 5 may include means for remote operation, increasing operator safety.

[0031] Optionally, the system also includes a spare hose reel 2 on the wheeled base 1 and three reserve reels, each hose reel 2 capable of storing a hose assembly with an electrical cable. In this configuration, two reel 2 supports can be used, fixed to the wheeled base 1 with safety locks and remote control operation, wherein the reels 2 have a geometric shape that prevents their unintentional movement when positioned on the ground.

[0032] In addition, it is optionally provided that the hose reels 2 comprise a coupling that enables docking with the implement for traction with remote control activation.

[0033] The drive reel 2 features a system for uniform hose distribution, variable speed with remote control activation that allows the system to be operated remotely, increasing operator safety.
