Coal mine geological survey water prevention and control drilling equipment

The utility model discloses coal mine geological survey water prevention drilling equipment which comprises a barrel, a first motor is fixedly connected to the top of the barrel, a driving wheel rotationally connected with the inner top wall of the barrel is inserted into the inner top wall of the barrel in a penetrating mode, the top of the driving wheel is fixedly connected with an output shaft of the first motor, and two sliding grooves are formed in the inner wall of the barrel. According to the utility model, through the arrangement of the two screw rods, the lifting block for driving the detection drill rod to descend is uniformly stressed, so that the abrasion of the screw rods is effectively reduced, and when the detection drill rod encounters a very hard object, the detection drill rod drives the mounting plate to ascend after being subjected to impact force, so that the impact force is buffered, and the detection drill rod is prevented from being damaged. According to the drilling machine, the abras
