Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 , the utility model provides a technical solution:

[0024] A convenient pile foundation depth detection device comprises a bottom plate 1, four groups of support columns 2 are symmetrically fixedly installed on the top of the bottom plate 1, the top ends of the four groups of support columns 2 are fixedly connected with a top plate 3, four groups of moving wheels 4 are symmetrically fixedly installed on the bottom of the bottom plate 1, four groups of leveling mechanisms 5 are symmetrically arranged on the bottom of the bottom plate 1, a through groove 6 is opened on the top of the bottom plate 1, an ultrasonic depth sounder 7 is fixedly installed on the bottom of the top plate 3, and the ultrasonic depth sounder 7 is located directly above the through groove 6. By arranging the leveling mechanism 5, it is possible to ensure that the pile foundation depth detection device maintains a stable horizontal state during the measurement process, and reduce the error caused by tilting. In addition, the design of the leveling mechanism 5 enables the pile foundation depth detection device to adapt to different terrain conditions. Whether it is on a flat ground or in complex terrains such as slopes and potholes, the detection device can be effectively leveled, which makes the convenient pile foundation depth detection device have a wider range of applications and can meet the detection needs of different engineering sites. The utility model is conducive to improving the measurement accuracy of pile foundation depth, enhancing equipment stability, adapting to different terrains, improving work efficiency and reducing safety risks.

[0025] The leveling mechanism 5 includes an L-shaped positioning plate 501, which is fixedly mounted on the top of the base plate 1, and a ball screw 502 is rotatably mounted on the inner bottom of the L-shaped positioning plate 501. The top of the ball screw 502 passes through the L-shaped positioning plate 501 and is connected to a driving motor 503. A moving block 504 is threadedly connected to the outer wall of the ball screw 502.

[0026] It also includes four groups of connecting rods 8, the top ends of the four groups of connecting rods 8 are fixedly connected to the bottom of the moving block 504, the bottom ends of the four types of connecting rods 8 pass through the bottom plate 1 and are connected to the linkage assembly 9, and the four groups of connecting rods 8 are slidably connected to the bottom plate 1;

[0027] Specifically, the output shaft of the driving motor 503 can drive the ball screw 502 to rotate in the forward or reverse direction, thereby driving the moving block 504 to reciprocate along the axial direction of the ball screw 502, thereby driving the four groups of connecting rods 8 to move;

[0028] The linkage assembly 9 includes a mounting plate 901, which is fixedly mounted on the bottom ends of the four groups of connecting rods 8, a universal ball knot 902 is fixedly connected to the bottom of the mounting plate 901, and a foot pad 903 is fixedly connected to the bottom of the universal ball knot 902;

[0029] Specifically, when the four groups of connecting rods 8 move, the mounting plate 901 can be driven to be raised and lowered. At this time, the fit between the foot pad 903 and the ground can be adaptively adjusted through the universal ball joint 902 to adapt to different terrains.

[0030] A limiting groove 10 is provided on one side wall of the L-shaped positioning plate 501, and a limiting block 11 adapted to the limiting groove 10 is fixedly connected to one side wall of the moving block 504. The limiting block 11 is slidably connected to the inside of the limiting groove 10. By setting the limiting groove 10 and the limiting block 11 in coordination, the moving block 504 is limited, making it more stable during operation.

[0031] The driving motor 503 is fixedly mounted on the top of the L-shaped positioning plate 501, one end of the output shaft of the driving motor 503 is fixedly connected to the top of the ball screw 502, and the driving motor 503 is configured as a forward and reverse stepping motor;

[0032] A level ruler 12 is fixedly installed on the top of the top plate 3. By setting the level ruler 12, it can be intuitively reflected whether the top plate 3 is in a horizontal state, so as to accurately level the ultrasonic depth sounder 7. Two sets of push-pull handles 13 are symmetrically fixedly installed on the upper surface of the top plate 3. By setting the push-pull handles 13 and the moving wheels 4, the moving wheels 4 can be set as universal wheels, which can facilitate the movement of the pile foundation depth detection device, thereby improving the convenience of using the device;

[0033] A control panel 14 is fixedly installed on the top of the bottom plate 1. The ultrasonic depth sounder 7 and the drive motor 503 are electrically connected to the control panel 14 through wires. The circuit connection is an existing mature technology. The specific connection method and working principle are not repeated here. The ultrasonic depth sounder 7 and the drive motor 503 can be started and stopped through the control panel 14. The ultrasonic depth sounder 7 can accurately detect the depth of the pile foundation due to its strong directionality and penetration. Its high-precision characteristics ensure that more accurate measurement results can be obtained even in complex environments. The ultrasonic depth sounder 7 is based on the reflection phenomenon of ultrasonic waves when propagating in different media. When ultrasonic waves encounter media of different densities, such as air and water or water and rock, reflection will occur. By measuring the time difference from the emission to the reception of the ultrasonic wave, combined with the propagation speed of the ultrasonic wave in the medium, the propagation distance of the ultrasonic wave can be calculated, and then the depth of the pile foundation can be obtained;

[0034] The ultrasonic transducer (probe) in the ultrasonic depth sounder 7 sends out ultrasonic signals. The signal frequency of the high-frequency transducer is generally around 200kHz, and the signal frequency of the low-frequency transducer is generally around 20kHz. Since the low-frequency signal has a long wavelength and a strong diffraction ability, it has a strong penetration ability and can penetrate a floating mud layer of a certain thickness. The ultrasonic signal propagates in the water. When it encounters the bottom of the pile foundation or other obstacles, it will be reflected. Assuming that the propagation speed of the ultrasonic wave in the water is V, and the time from the emission to the reception of the ultrasonic wave is t, the distance of the ultrasonic wave propagation is Vt. The reflected ultrasonic signal is received by the ultrasonic transducer. By measuring the time t from the emission to the reception of the ultrasonic wave, and combining the known propagation speed V of the ultrasonic wave in the water, the distance of the ultrasonic wave propagation (i.e., the water depth) can be calculated: Z=Vt / 2. At the same time, the distance between the water surface and the probe (i.e., the draft depth) can be obtained according to the scale of the fixed rod on the probe. The sum of the two is the final water depth value (pile foundation depth).

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
