Description

Technical Field

[0001] The invention relates to the technical field of geological detection, and in particular to a hydrogeological drilling detection device with a blocking structure. Background Art

[0002] The hydrogeological drilling detection equipment with a plugging structure was born against the background of the continuous development of hydrogeological drilling technology. Compared with general geological drilling, hydrogeological drilling has the characteristics of larger borehole diameter and complex drilling process, and the equipment used is also larger. In the actual drilling process, in order to effectively prevent the entry of soil, moisture, etc. into the borehole during the drilling process, and at the same time avoid blockage and pollution of the aquifer, special drilling equipment is required. The hydrogeological drilling detection equipment with a plugging structure came into being. It can achieve the effect of drilling and plugging during the drilling process, effectively improving the accuracy and efficiency of drilling, and providing strong technical support for hydrogeological exploration and development.

[0003] After searching, the Chinese patent number CN115839861A discloses a hydrogeological drilling detection device, including a detection support frame, a detection box body is fixedly connected to the detection support frame, a through hole is opened in the middle of the bottom end of the detection box body, the through hole is connected to the inside of the detection box body, a drilling box body is arranged in the through hole, a lifting assembly is arranged in the detection box body, the drilling box body is slidably connected to the through hole through the lifting assembly, a multifunctional drilling assembly is arranged at the bottom end of the drilling box body, a plugging assembly is arranged on the multifunctional drilling assembly, the plugging assembly and the multifunctional drilling assembly are arranged correspondingly, and the four corners of the bottom end of the detection support frame are provided. They are all equipped with moving wheels, and a stable support assembly is arranged on the detection support frame. The stable support assembly is arranged corresponding to the moving wheel. A handrail is fixedly connected to one side of the detection support frame. Compared with the prior art, the Chinese patent number CN115839861A solves the problem that the hydrogeological detection equipment in the prior art can usually only realize a single exploration sampling operation, that is, separate soil sampling and separate water sampling, and has a small scope of application. At the same time, the current sealing method for water sampling is to inject weighted mud between the drill bit and the hole wall for sealing, and the controllable accuracy of cement solidification time is poor.

[0004] However, in actual use of the above device, when hydrogeological drilling detection is carried out for water sampling, water sources of different water layers will be encountered depending on the drilling depth. It is easy to mistakenly take samples from different water layers when taking water samples, thereby affecting the sample quality. Therefore, a hydrogeological drilling detection device with a sealing structure is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings in the prior art that when hydrogeological drilling detection is carried out for water sampling, water sources of different water layers will be encountered depending on the drilling depth, and it is easy to mistakenly take samples from different water layers during water sampling, thereby affecting the quality of the samples. A hydrogeological drilling detection equipment with a blocking structure is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A hydrogeological drilling detection device with a plugging structure comprises a device base, a rotating rod is arranged at the front end of the device base, a plugging plate is slidably connected to the upper part of the rotating rod, two gripping shells are fixedly connected to the upper part of the plugging plate, a third motor is arranged inside the gripping shell, a third gear is arranged at the output end of the third motor, the third gear is meshingly connected to a fourth gear, the fourth gear is rotationally connected to the gripping shell, a gripping nail is threadedly connected to the fourth gear, a collecting chamber is fixedly connected to the lower part of the rotating rod, a drilling rod is fixedly connected to the lower part of the collecting chamber, a drilling drill bit is fixedly connected to the lower part of the drilling drill bit, an air pump is arranged at the upper part of the drilling drill bit, and a plugging air bag is arranged at the upper part of the air pump;

[0008] When the device is in use, the rotating rod moves downward and drills into the ground. When the rotating rod moves, the sealing plate arranged on the upper part is driven to contact the ground. Then the third motor is started to drive the fourth gear to rotate. The rotation of the fourth gear drives the gripping nails to move downward and drill into the ground to fix the sealing plate to the ground and seal the borehole. When sampling, the air pump is used to ventilate the inside of the sealing airbag. The sealing airbag is inflated by the air and fits the borehole to seal the water layer. The diameter of the sealing airbag arranged on the upper part of the drilling drill bit is slightly larger than the drilling drill bit.

[0009] The above technical solution further includes:

[0010] The lower part of the drilling bit is fixedly connected with an automatic closing mechanism, and the automatic closing mechanism drives the movable baffle arranged inside to rotate, so as to control the opening and closing of the bottom of the drilling bit.

[0011] The automatic sealing mechanism comprises a sealing shell fixedly connected to the bottom of the drilling bit, a fourth motor is arranged inside the sealing shell, and a sealing component is arranged at the output end of the fourth motor.

[0012] The closed component includes a fifth gear arranged at the output end of the fourth motor, the fifth gear is meshingly connected with the sixth gear, five eccentric shafts are fixedly connected to the bottom of the sixth gear, a movable baffle is rotatably connected to the lower part of the eccentric shaft, and the movable baffle is rotatably connected to the closed shell.

A second motor is arranged on the upper part of the transmission plate, and a rotating rod is arranged at the output end of the second motor. Four limit rods are arranged inside the drilling frame, and the transmission plate is slidably connected to the limit rods.

[0017] A push rod is fixedly connected to the upper part of the equipment base, and four wheels are arranged at the bottom of the equipment base, through which the whole equipment can be driven to move.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, when the device is used, the rotating rod will gradually drill into the ground. As the rotating rod continues to move downward, the blocking plate will contact the ground driven by the rotating rod. Then, the third motor can be started to drive the gripping nails to move downward. The blocking plate can be fixed by controlling the gripping nails to be inserted into the ground, thereby blocking the upper part of the borehole and effectively ensuring that groundwater will not spray out. When the drilling bit is sampling water, controlling the air pump to inflate the blocking airbag can quickly drive the blocking airbag to expand, thereby blocking the upper part of the drilling bit, thereby effectively avoiding the drilling bit from extracting water from different water layers when sampling.

During the movement of the transmission plate, the four limit rods arranged on the drilling frame can effectively ensure the stability of the transmission plate during movement, thereby improving the positioning effect of the drilling bit.

[0032] When the device is in use, the rotating rod 7 moves downward and drills into the ground. When the rotating rod 7 moves, the sealing plate 9 arranged on the upper part is driven to contact the ground. Then the third motor 16 is started to drive the fourth gear 18 to rotate. The rotation of the fourth gear 18 drives the gripping nails 19 to move downward and drill into the ground to fix the sealing plate 9 to the ground and seal the borehole. When sampling, the air pump 20 is used to ventilate the inside of the sealing airbag 21, and the sealing airbag 21 is expanded by the air and fits the borehole to seal the water layer.
