[0025] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0026] The utility model provides a pile hole depth measuring device, see Figure 1 and Figure 2 The pile hole depth measuring device includes a shell 1, a winding wheel, a hanging wire 6, a weight 8, a counting chip, a photoelectric counting sensor and a display screen 4; wherein the winding wheel is rotatably arranged in the shell 1, the hanging wire 6 is wound on the winding wheel, a rotating handle 2 is provided on one side of the shell 1, and the rotating handle 2 is fixedly connected to one end of the winding wheel; a wire outlet hole 11 is opened at the bottom of the shell 1, and one end of the hanging wire 6 passes through the wire outlet hole 11 and is connected to the weight 8; a plurality of scale rings 61 are evenly spaced on the hanging wire 6; the counting chip and the display screen 4 are both arranged on the shell 1, the photoelectric counting sensor is arranged at the wire outlet hole 11, and the photoelectric counting sensor and the display screen 4 are both electrically connected to the counting chip.

[0027] Specifically, Figure 1 The middle weight 8 is not connected to the suspension line 6. When in use, the weight 8 is connected to the end of the suspension line 6. The winding wheel in the housing 1 is rotated by turning the rotating handle 2 to release the suspension line 6 from the outside of the housing 1. The weight 8 moves to the bottom of the pile hole under the action of gravity. During the release of the suspension line 6, when the scale ring 61 on the suspension line 6 passes through the outlet hole 11, the photoelectric counting sensor arranged at the outlet hole 11 senses the scale ring 61 passing through the outlet hole 11 and counts once, and transmits the signal to the counting chip. The counting chip calculates the length of the released suspension line 6 according to the number of scale rings 61 passing through the outlet hole 11 detected by the photoelectric counting sensor, and displays the value on the display screen 4. When the weight 8 is released to the bottom of the pile hole, the value displayed on the display screen 4 is the depth of the pile hole.

[0028] In this embodiment, the housing 1 is a circular box-shaped structure, and the winding wheel is rotatably arranged at the center of the housing 1. Such an arrangement can make the housing 1 compact in structure, small in size and light in weight, and convenient to carry and store.

[0029] Preferably, the display screen 4 is disposed on a side surface of the housing 1, and the display screen 4 is located on the side surface away from the wire outlet hole 11. Figure 1As shown, in this embodiment, the display screen 4 and the rotating handle 2 are both located on the front side of the outside, so that the operator can observe the value on the display screen 4 in real time when the rotating handle 2 is manually cranked. The rotating handle 2 is a commonly used Z-shaped hand crank. A lifting handle 3 is rotatably provided on the housing 1. The lifting handle 3 is in a "U"-shaped structure, and the two ends of the lifting handle 3 are rotatably connected to the housing 1, and the two ends of the lifting handle 3 are located between the outlet hole 11 and the display screen 4. By providing the lifting handle 3, when the device is in use, the operator can operate it by holding the lifting handle 3 by hand, or hook the lifting handle 3 on a fixed structure above the pile hole for fixing. The two ends of the lifting handle 3 are located between the outlet hole 11 and the display screen 4. When measuring the depth of the pile hole, the hanging wire 6 is released from the outlet hole 11 below the housing 1, and the display screen 4 is located on the upper part of the housing 1, which makes it more convenient for the operator to observe the value displayed on the display screen 4.

[0030] Furthermore, a reset button 5 is provided on one side of the display screen 4, and the reset button 5 is electrically connected to the counting chip. Before using the pile hole depth measuring device, the reset button 5 can be pressed to reset the number on the display screen 4, and then the hanging wire 6 can be released. When the heavy hammer 8 is released to the bottom of the pile hole, the value displayed on the display screen 4 is the accurate depth of the pile hole. After the measurement is completed and the hanging wire 6 is retracted, the reset button 5 can be pressed again to reset the value on the display screen 4.

[0031] The device can be powered by an external power source or by a storage battery. When powered by a storage battery, a groove and a groove cover for accommodating the storage battery can be provided on one side of the housing 1, and the storage battery is installed in the groove and covered with the groove cover for protection.

[0032] In this embodiment, the end of the suspension line 6 located outside the housing 1 is connected to a self-locking shackle 7, and the weight 8 is detachably connected to the self-locking shackle 7. By providing the self-locking shackle 7, the quick connection and disassembly between the weight 8 and the suspension line 6 are facilitated. When the device is not in use, the weight 8 can be removed from the self-locking shackle 7 and placed in a separate weight 8 storage box for storage.

[0033] Furthermore, the suspension wire 6 is a tungsten metal wire, and the weight 8 is a tungsten metal hammer. By using a tungsten metal hammer, the depth of the pile hole can be measured in a pile hole with mud. The tungsten metal hammer has a large density and can overcome the buoyancy of the mud and sink to the bottom of the pile hole, thereby accurately measuring the depth of the pile hole; the use of tungsten metal wire can make the suspension wire 6 have a higher tensile strength, avoiding the suspension wire 6 from being broken due to the adsorption force of the mud when the weight 8 in the mud is pulled. In this embodiment, the suspension wire 6 uses a tungsten metal wire with a diameter of 1 mm.

[0034] like Figure 3, which is a schematic diagram of the arrangement of the scale ring 61 on the suspension wire 6. The scale ring 61 can be anchored on the suspension wire 6. The spacing between the scale rings 61 on the suspension wire 6 determines the measurement accuracy of the pile hole depth. In this embodiment, a scale ring 61 is arranged on the suspension wire 6 every 0.5m, and the pile hole depth measurement accuracy is 0.5m.

[0035] See also Figure 4 In this embodiment, the weight 8 includes a hammer body 81 and a connecting handle 82. The hammer body 81 is a conical structure. The hammer body 81 with a conical structure can reduce the resistance of the weight 8 to sink in the mud. The connecting handle 82 is a "U"-shaped structure. The connecting handle 82 is connected to the circular end face of the conical structure of the hammer body 81. The self-locking hook ring 7 can be connected to the connecting handle 82. Among them, a connecting groove 821 is also provided in the middle position of the connecting handle 82. The connecting groove 821 is a ring groove. The self-locking hook ring 7 can be hooked in the connecting groove 821, so as to prevent the hook ring from sliding on the connecting handle 82 to cause the weight 8 to tilt, and the weight 8 can be kept in a vertical state during the descent process, so that it can sink better in the mud. The upper part of the hammer body 81 of the weight 8 can also be set as a hollow groove structure. The weight 8 with this structure can reduce the mass of the weight 8 and is used when measuring the depth of the pile hole without mud. The weight 8 can be removed from the self-locking hook 7 when not in use and placed in a storage box for storing the weight 8 .

[0036] Furthermore, scale values are respectively provided on the scale rings 61, and the scale values are the lengths of the suspension wire 6 between the corresponding scale rings 61 and the ends of the suspension wire 6. With such a configuration, when the device is used to measure the pile hole depth, the measured pile hole depth can be read not only through the numerical value on the display screen 4, but also through the scale values on the scale rings 61, thereby avoiding the situation where the device cannot be used when the display screen 4 or the photoelectric counting sensor fails.

[0037] In summary, the pile hole depth measuring device provided by the utility model can drive the winding wheel in the housing to rotate by rotating the handle to release the hanging line connected to the heavy hammer at the end, and lower the heavy hammer to the bottom of the pile hole. When the hanging line is lowered, the photoelectric counting sensor at the outlet hole can count the scale ring passing through the outlet hole and transmit it to the counting chip. After calculation and processing, the counting chip displays the released length of the hanging line on the display screen, thereby conveniently completing the pile hole depth measurement. The pile hole depth measuring device is simple to operate, convenient to measure, and can complete the depth measurement of pile holes with mud.
