[0028] Embodiment 1

[0029] A geotechnical engineering exploration hole depth measuring device, as Figures 1-5 shown, includes a fixed bracket 1. Connecting holes are opened on both inner walls at the bottom end of the fixed bracket 1; the device can be conveniently fixed to the ground by using the connecting holes and external fasteners to prevent the device from tipping over due to its own or external reasons during measurement.

[0030] A measuring assembly is arranged above the fixed bracket 1. The measuring assembly includes a wire roller 201 rotatably connected to one side surface of the fixed bracket 1, a motor 2 fixedly connected to the outer wall of one side of the fixed bracket 1 through a top plate, a measuring rope 202 wound around the circumferential outer wall of the wire roller 201, and a counterweight ball 6 tied to one end of the measuring rope 202; after placing the counterweight ball 6 at the hole opening, start the motor 2 to drive the wire roller 201 to rotate, and then take in and release the measuring rope 202 wound thereon, so that the counterweight ball 6 can pull the used length of the measuring rope 202 when lowering, and finally the depth of the hole can be understood according to the numerical indication on the measuring rope 202, which is relatively convenient to use.

[0031] Preferably, the counterweight ball 6 can be made of metal to ensure it has a certain "leading" weight. A plurality of thorn cones are welded on the circumferential outer wall of the counterweight ball 6; when the counterweight ball 6 is lowered to test the hole depth and encounters obstacles such as soil blocks, the counterweight ball 6 is shaken passively through the measuring rope 202, and the thorn cones on its surface are used to quickly break through the obstacles, so as to be able to continue to lower and move forward, assisting in improving the measurement accuracy.

[0032] Further preferably, a locator 14 is fixedly connected and placed inside the counterweight ball 6. The prior art is cited here and will not be elaborated; it is convenient for people to understand the moving position of the counterweight ball 6 in real time, and be able to intervene in time when it is intercepted and stays midway.

[0033] A positioning hole 3 is opened on the top surface of the fixed bracket 1 below the wire roller 201; one side surface of the fixed bracket 1 near the bottom end is fixed with a support plate 5 by bolts. A guiding hole is opened on one side surface of the support plate 5, and a through hole 10 is opened on the top surface near one side of the support plate 5. An anti-stagnation component is arranged inside the through hole 10;

[0034] Further, the anti-stagnation component includes a hollow turntable 4 adapted to the inner diameter of the through hole 10, an annular groove 11 formed on the circumferential inner wall surface of the through hole 10, an annular plate 1101 welded to the circumferential outer wall of the turntable 4 and slidably engaged with the annular groove 11, upper and lower wire passing holes 401 formed on the top and bottom surfaces of the turntable 4, and three or more metal balls 13 placed inside the turntable 4;

[0035] Preferably, a handle 12 is welded to the top surface of the turntable 4;

[0036] More preferably, the outer wall of the metal ball 13 is in contact with the outer wall of the measuring rope 202; after one end of the measuring rope 202 is released from the wire roller 201, it passes through the positioning hole 3, the guiding hole in sequence and then passes through the wire passing hole 401 in the turntable 4, so that the metal ball 13 surrounds the outside of the measuring rope 202 and is then tied to the counterweight ball 6. Moreover, during the measurement of the hole depth, when it is observed that the measuring rope 202 no longer descends, the handle 12 can be held to drive the turntable 4 to rotate rapidly in a reciprocating manner within the through hole 10. During this period, the metal ball 13 inside the turntable 4 continuously rubs against the measuring rope 202 and drives it to rotate by mutual extrusion, so that the counterweight ball 6 can move under the action of the swaying measuring rope 202. The possible obstacles can be broken by the impact of the counterweight ball 6, so that the counterweight ball 6 can continue to descend under its own weight, or it can be ensured by the movement that the counterweight ball 6 has reached the bottom layer of the hole, which can effectively ensure the accuracy of the hole depth measurement and is relatively convenient to operate.

[0037] Working principle: The equipment is conveniently fixed to the ground by using the connection hole and external fasteners. After one end of the measuring rope 202 is released from the wire roller 201, it passes through the positioning hole 3, the guiding hole in sequence and then passes through the wire passing hole 401 in the turntable 4, so that the metal ball 13 surrounds the outside of the measuring rope 202 and is then tied to the counterweight ball 6. After the counterweight ball 6 is placed at the hole opening, the motor 2 is started to drive the wire roller 201 to rotate, and then the measuring rope 202 wound thereon is retracted and released, so that the use length of the measuring rope 202 can be pulled when the counterweight ball 6 descends. During the test of the hole depth when the counterweight ball 6 descends, when it is observed that the measuring rope 202 no longer descends, the handle 12 can be held to drive the turntable 4 to rotate rapidly in a reciprocating manner within the through hole 10. During this period, the metal ball 13 inside the turntable 4 continuously rubs against the measuring rope 202 and drives it to rotate by mutual extrusion, so that the counterweight ball 6 can move under the action of the swaying measuring rope 202. The possible obstacles can be broken by the impact of the counterweight ball 6, so that the counterweight ball 6 can continue to descend under its own weight, or it can be ensured by the movement that the counterweight ball 6 has reached the bottom layer of the hole, which can effectively ensure the accuracy of the hole depth measurement. Finally, the depth of the hole can be understood according to the numerical indication on the measuring rope 202.

[0038] Embodiment 2

[0039] A geotechnical engineering exploration hole depth measurement device, as Figures 1-2 shown. In order to assist people in judging that the counterweight ball 6 has reached the bottom of the hole or has been intercepted by an obstacle midway; the following improvements are made on the basis of Embodiment 1 in this embodiment: Two support plates 7 are symmetrically fixedly connected to the top surface of the support plate 5. Slide grooves 701 are formed on the corresponding side surfaces of the two support plates 7. A moving plate 9 is slidably connected to the inner wall of the slide groove 701 through a slider. The same I-shaped wheel 901 is rotatably connected to the corresponding side surfaces of the two moving plates 9. And a spring 8 is welded between the slide groove 701 and the slider;

[0040] The measuring rope 202 passes through the positioning hole 3 and then bypasses the lower part of the I-shaped wheel 901 and is introduced into the guiding hole. Under normal operation conditions, when the wire roller 201 releases the wire at an appropriate speed, the measuring rope 202 will fit against the outer wall of the bottom of the I-shaped wheel 901 and pull the moving plate 9 to move upward, causing the spring to contract. When the counterweight ball 6 no longer falls, since the wire roller 201 still continuously releases the wire, the measuring rope 202 will accumulate in the area of the support plate 5 below the I-shaped wheel 901. Through this structure, people can be assisted to judge that the counterweight ball 6 has reached the bottom of the hole or has been intercepted by an obstacle midway through the anti-stagnation component, which is convenient to use.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
