The invention also provides a using method of the drilling water level measuring device, which comprises the following steps:
when detecting the drilling, the staff places the water level pipe in the drilling, extrude the bottom at the drilling when the extrusion platform, along with water level pipe continuous downwardly moving, fourth slide bar is along water level pipe bottom upward movement, the fifth spring is compressed, water level pipe is along the connecting rod downwardly moving, under the supporting role of four connecting rods, two slip rings upwards slide for the water level pipe, the slip ring drives the second articulated rod on it and upwards moves, the upper end and the adjacent first articulated rod cooperation of second articulated rod, make the extrusion plate outwards expand on the lower extreme drive of first articulated rod, the extrusion plate extrusion laminating is at the inner wall of drilling, utilize the outside expansion of adjacent extrusion plate to right the water level pipe, make the axis of water level pipe and the axis coincidence of drilling.
In the process that the water level pipe moves downwards along the fourth sliding rod, a circular plate at the upper end of the fourth sliding rod is matched with two tooth plates, and the two tooth plates are matched with the circular plate on the fourth sliding rod to limit the fourth sliding rod.
In the process that the water level pipe moves downwards along the drill hole, the extrusion table is limited by utilizing a fifth spring, so that adjacent extrusion plates are kept close to the water level pipe in the process of moving downwards along the drill hole, and the phenomenon that broken stones and soil blocks on the inner wall of the drill hole fall to cause the blockage of the lower side of the drill hole due to scratch with the inner wall of the drill hole is avoided; the extrusion table is arranged to be in a frustum shape, and broken stone can roll downwards when falling on the extrusion table in a drilling hole, so that the broken stone is prevented from being located on the upper side of the extrusion table and blocked when the extrusion table and the water level pipe are close to each other.
After the water level pipe is installed, a worker fixes the water level pipe and the ground, water in a drilled hole enters the water level pipe through the drain plate and the filter membrane, the drain plate and the filter membrane are utilized to filter the water, so that the situation that the surrounding soil fine particles enter the water level pipe to cause clogging is avoided, the worker places a round shell connected with a traction rope and other parts on the round shell into the water level pipe, the rotating wheels at the outer ends of four second sliding rods are extruded on the inner wall of the water level pipe, the second sliding rods slide along the adjacent fixed shells, the second springs are compressed, the round shell is straightened by the four second sliding rods, the round shell and the floats move up and down along the central axis of the water level pipe, the traction rope is ensured to be positioned on the central axis of the water level pipe and kept vertical, and the phenomenon that the traction rope swings in the water level pipe is avoided, so that the traction rope deflects to reduce the accuracy of measuring the water level of the drilled hole; after the buoy contacts the liquid level of water in the water level pipe, the buoy is on the upper side of the liquid level, the distance between the buoy and the bottom plate is unchanged under the action of the elastic force of the first spring, meanwhile, the winding counting device is controlled by the control terminal, the traction rope is always kept in a straight state, the winding counting device calculates the stretching distance of the traction rope in real time along with the up-and-down movement of the position of the buoy along with the change of the height of the liquid level in the water level pipe, so that the water level in the water level pipe is obtained, signals are emitted to a remote terminal through an antenna, and meanwhile, the solar panel supplies power to the control terminal, so that the measuring device can measure the water level of the water level pipe in real time.
When broken stone in a drilled hole falls, the liquid level in the water level pipe can be caused to float up and down, the float moves upwards along with the impact of the liquid level on the liquid level, the inertial circular shell is kept motionless, the float drives the first sliding rod to slide upwards along the bottom plate, the circular shell and the traction rope are buffered by the first spring between the bottom plate and the float, the traction rope is prevented from being pulled in the process of floating up and down, the traction rope is prevented from being pulled and damaged for a long time, and meanwhile, the detected number can not be changed drastically along with the floating of the liquid level; when first slide bar upwards slides along first spline pole, the third spring is compressed, make the toper piece upwards slide along first spline pole under the elasticity effect of third spring, the hydraulic oil between circular shell and the bottom plate flows in the arc through-hole of toper piece, make the toper piece upwards move the in-process receive the resistance of hydraulic oil and reduce, the ball of four third slide bar inner receives the toper piece extrusion, four third slide bars all are close to the water level pipe lateral wall and remove, the extension spring is stretched, the friction disc extrusion in four arc friction plates outsides is at the water level pipe lateral wall, play the effect to circular shell is spacing, the upper and lower float of circular shell is reduced, avoid the continuous shrink of haulage rope to stretch, lead to the haulage rope to produce fatigue damage for a long time, improve the stability of rolling counting assembly to water level measurement numerical value simultaneously.
The cursory liquid level that floats from top to bottom removes along with, after the cursory range of floating from top to bottom diminishes, first slide bar resets under the elasticity effect of first spring, the third spring pulls the toper piece downwards, the toper piece makes it follow first spline pole downwardly moving, when the toper piece downwardly moving, when three baffle-plates receive the resistance of hydraulic oil, baffle-plates upwards move along adjacent second spline pole, baffle-plates and adjacent toper piece's arc through-hole cooperation, the fourth spring is compressed, hydraulic oil passes through from baffle-plates's circular through-hole, improve hydraulic oil flow's resistance, realize the effect that the toper piece slowly resets, slowly reduce the extrusion force between arc friction plate and the water level pipe, make four third slide bars reset under the extension spring effect, after the arc friction plate resets completely, the surface of water in the water level pipe has kept steady state.
In summary, due to the adoption of the technical scheme, the beneficial effects of the invention are as follows:
1. utilize adjacent stripper plate outwards to expand, make the axis of water level pipe and the central line coincidence of drilling, avoid the water level pipe not taking place the slope in the drilling between two parties, lead to the measuring value inaccuracy to drilling water level to the expansion distance between the adjacent stripper plate is along with the distance between water level pipe and the extrusion platform reduces and increases, has realized that the water level pipe is applicable to in the drilling of different diameters.
2. Two tooth plates are matched with circular plates on the fourth sliding rod to limit the fourth sliding rod, so that the soil at the bottom of a drilled hole is prevented from being soft, an extrusion table is inserted into soft soil under the action of a spring for a long time, the extrusion plates are caused to lose extrusion contact with the side wall of the drilled hole, and the adjacent extrusion plates lose the righting and fixing effects on a water level pipe.
3.
