Groundwater drilling equipment

Technical Field

The invention relates to the technical field of groundwater drilling equipment, in particular to a groundwater drilling device.

Background technique

Hydrogeological drilling is a major technical means used to obtain the data needed for the rational development and utilization of groundwater. Compared with general geological drilling, the characteristics of hydrogeological drilling are larger borehole diameter, more complex drilling and well-forming processes, and larger equipment capacity. Hydrogeological drilling holes can generally be divided into three types: hydrogeological survey holes, hydrogeological exploration holes, and exploration and mining combined holes.

A groundwater artificial observation channel drilling equipment with publication number CN116136151B relates to the field of groundwater observation technology, including a through-mouth base, and wheeled legs are fixedly installed at the four corners of the bottom end of the through-mouth base. A top frame is fixedly installed on the through-mouth base, and also includes a hole expansion and drilling assembly, a protective cylinder and a supporting assembly. The hole expansion and drilling assembly includes a multi-stage hydraulic rod arranged above the top frame, and the ends of the multi-stage hydraulic rods are connected to a pressure unit. The hole expansion and drilling assembly also includes an expansion cylinder arranged below the pressure unit, and a coaxially arranged drill rod is fixedly installed at the bottom end of the expansion cylinder. The protective cylinder is used for protecting the borehole opening. When drilling an artificial observation channel, this application can simultaneously install the protective cylinder, and use the protective cylinder to provide good support and protection for the hole opening, thereby avoiding collapse and deformation of the hole opening during subsequent construction, and improving the convenience of subsequent reinforcement construction operations.

However, the prior art has the following problems: first, in the prior art, a protective tube is installed at the hole, and the supporting effect of the protective tube is used to support and protect the hole to prevent the hole from collapsing or deforming. However, the supporting range of the protective tube in the application cannot be adjusted, and the supporting range of the protective tube cannot be adaptively adjusted according to the size of the drill bit or the size of the hole to be opened. The only way is to replace the protective tube of the corresponding size according to demand, which is troublesome and costly. Second, when groundwater is drilled and the water pressure is too high, causing the groundwater and underground air to spray upward to the outside of the hole at a relatively high speed, the protective tube may be pushed up due to the impact force of the water flow or air, and lose its supporting effect on the hole, or cause impact on the drill bit of the drilling rig, affecting the drilling operation.

When the device is in use, the drill rig 2 is first controlled to open a drilling hole in the drilling area. Then, according to the size of the drill bit and the size of the drilling hole to be opened, the inner area where the three support frames 31 are hinged to each other is the support area. Then, according to the size of the drill bit and the size of the drilling hole to be opened, the support range of the three support frames 31 is adjusted with the cooperation of the support range adjustment component 32. After the adjustment is completed, the support area inside the three support frames 31 is consistent with the size of the drilling hole. Then, support columns 34 are installed in the mounting holes 33 at the bottom of the three support frames 31 within the support area. Then, the support frames 31 are placed on the ground. The support columns 34 in the support area are inside the hole and the support columns 34 are in contact with the inner wall of the hole, so as to support the hole. The rest of the support frames 31 are placed on the ground. , which plays a supporting effect on the support frame 31 as a whole. During the drilling process of the drilling rig 2, if groundwater is drilled and the water pressure is too high, causing the groundwater and underground air to spray upward to the outside of the hole at a relatively high speed, the water flow and gas enter the support frame 31 through the support column 34 in the drilling hole. With the cooperation of the pressure relief component 35, the water pressure and air pressure are relieved and buffered, thereby reducing the impact force of the water flow and air on the support frame 31, and avoiding excessive water flow impact affecting the drilling work of the drilling rig 2.

The side end of the locking block 322 passes through the side groove of the articulated frame 321 and is rotatably connected to the articulated frame 321. The locking block 322 is provided with an adjusting button 324.

When the support area inside the three support frames 31 needs to be adjusted according to the size of the drilling hole, firstly, the locking blocks 322 of the locking grooves 323 inside the three support frames 31 are rotated by adjusting knobs 324 respectively, so that the locking blocks 322 are disengaged from the locking grooves 323, so that the articulated frames 321 can slide on the support frames 31, and then the articulated frames 321 on the support frames 31 are controlled to slide on the locking grooves 323 on the adjacent support frames 31 by the same length, and then the locking blocks 322 are rotated again. It is stuck in the locking groove 323, thereby locking the position of the articulated frame 321 in the locking groove 323, thereby realizing the adjustment of the size of the inner support area of the three support frames 31, and then a corresponding number of support columns 34 are inserted into the mounting holes 33 in the support area at the bottom of the support frame 31, and then placed at the hole opening to achieve the support effect of the hole opening, thereby realizing the diameter of the drilling hole that can be opened according to the needs, and the support range can be adjusted in time without replacing the support device.

In this embodiment, as shown in FIG5 , a rubber layer is provided on the outside of the locking block 322;

By providing a rubber layer on the outer side of the locking block 322, the friction between the surface of the locking block 322 and the inner side of the locking groove 323 is enhanced, thereby increasing the resistance between the locking block 322 and the locking groove 323, thereby further improving the stability of the three support frames 31 after adjusting the support range.

According to the size of the support area formed by the three support frames 31, a corresponding number of support columns 34 are detachably installed on the mounting holes 33 in the support area through internal and external threads, and then the support frame 31 is placed on the ground. The support columns 34 in the support area are located inside the hole and the support columns 34 are in contact with the inner wall of the hole, thereby providing support for the hole. The rest of the support frame 31 is placed on the ground, thereby providing support for the support frame 31 as a whole.

In this embodiment, as shown in FIG. 7 , the pressure relief assembly 35 includes a pressure relief block 351 and a first spring 352. The pressure relief block 351 is disposed inside the support frame 31 and is slidably connected thereto up and down. The bottom of the pressure relief block 351 contacts the bottom surface inside the support frame 31 and covers the top of the mounting hole 33. The first spring 352 is disposed inside the support frame 31. The upper and lower ends of the first spring 352 are respectively connected to the top of the pressure relief block 351 and the top of the inside of the support frame 31.

When groundwater is drilled and the water pressure is too high, causing the groundwater and underground air to erupt upward to the outside of the cave entrance at a relatively high speed, the groundwater or airflow will enter the interior of the support column 34 located in the cave entrance, and enter the support frame 31 through the support column 34, pushing up the pressure relief block 351 located in the support frame 31, and the first spring 352 shrinks quickly. The sliding of the pressure relief block 351 and the shrinkage of the first spring 352 can relieve the pressure of the water flow and air flow, and the impact force is buffered. At the same time, the water flow enters the interior of the support frame 31, thereby achieving the effect of avoiding the water flow from impacting the drilling rig 2 and causing the drill bit to deviate and affect the drilling operation while relieving the pressure.

In this embodiment, as shown in Figure 8, the support assembly 36 includes an insert rod 361, a second spring 362, a matching block 363, a pressure block 364 and a third spring 365. The pressure relief block 351 is hollow and has through holes on both sides of the pressure relief block 351. The bottom end of the insert rod 361 is sharp and passes through the bottom of the pressure relief block 351. After passing through the bottom of the pressure relief block 351, the insert rod 361 can continue to pass through the support frame 31 and be used to contact the ground. The insert rod 361 is slidably connected to the bottom of the pressure relief block 351 up and down, the matching block 363 is arranged at the top of the insert rod 361, the upper and lower ends of the second spring 362 are respectively connected to the bottom of the matching block 363 and the bottom end inside the pressure relief block 351, the pressure block 364 is vertically arranged at the through-hole on one side of the pressure relief block 351, and the bottom of the pressure block 364 is hinged to the bottom end inside the pressure relief block 351, the two ends of the third spring 365 are respectively connected to the side end of the pressure block 364 and the bottom end inside the pressure relief block 351, and the top of the matching block 363 is provided with a beveled edge on one side close to the pressure block 364;

When the pressure relief block 351 located inside the hole is impacted and lifted up, the airflow and water flow horizontally inside the support frame 31 toward the direction of the pressure relief block 351 that is not lifted up and is located above the ground. During the flow, the airflow and water flow pass through the through holes of each pressure relief block 351 that is not lifted up in turn, and press the pressure block 364 downward in turn to flip it in the direction of the matching block 363, and then press the matching block 363 downward, so that the insertion rod 361 descends and drills into the ground, thereby making the connection between the support frame 31 and the ground more stable, thereby avoiding the problem of the support frame 31 being separated from the hole due to impact, and making the support effect of the device on the hole more stable.
