[0025] In addition, the expressions “first”, “second”, “third”, etc. in the terms are merely used to distinguish the description of the same or similar components, and should not be understood as emphasizing or implying the relative importance of specific components.

[0026] In addition, in the description of the embodiments of the present invention, "several", "a plurality", and "a number" represent at least 2. It can be any number such as 2, 3, 4, 5, 6, 7, 8, 9, and even more than 9.

[0027] Furthermore, in the description of the technical solutions of this utility model, unless otherwise expressly specified / defined / restricted, the terms "disposed," "installed," "connected," "connected," "provided with," "laid," and "arranged" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections. They may be welding, riveting, bolting, threading, or other commonly used connection methods in the art. Such connections may be mechanical, electrical, or communication connections; they may be direct connections, indirect connections through an intermediate medium, or internal connections between two components.

[0028] This embodiment provides a pile bottom detection system. Figure 1 The pile bottom detection system may include a control console 110, a detector 120, a data transmission cable 130, and a cable retraction device 140. The data transmission cable 130 connects the control console 110 and the detector 120. The cable retraction device 140 may include a guide bracket 141 and a reel 142. The data transmission cable 130 can be wound around the reel 142. The reel 142 can be rotated forward or reverse to retract and extend the data transmission cable 130.

[0029] See also Figure 2 The detector 120 may include a camera 121 and a liquid level sensor 122. The camera 121 and the liquid level sensor 122 are both communicatively connected to the console 110 via a data transmission cable 130. Preferably, the liquid level sensor 122 is connected to the camera 121 in a suspended manner, so that when the camera 121 and the liquid level sensor 122 move in the well, the liquid level sensor 122 is always suspended directly below the camera 121.

[0030] Preferably, the control console 110 and the cable retracting device 140 are arranged at the personnel working surface, and the guide bracket 141 is set up at the wellhead. The data transmission cable 130 can be lowered into the well through the guide bracket 141. The guide bracket 141 can be a pulley installed at the wellhead.

[0031] See also Figure 2 Preferably, the camera 121 may include a lens 101, a cylindrical housing 102, and a camera data cable 103. The lens 101 is embedded in one end of the cylindrical housing 102. The other end of the cylindrical housing 102 is connected to the console 110 via the camera data cable 103. Preferably, the camera 121 may be a panoramic camera, an ultra-wide-angle camera, or the like.

[0032] Liquid level sensor 122 may include a probe 104, a liquid level sensor data cable 105, and a mounting plate 106. Probe 104 is embedded in the center of mounting plate 106 and connected to control console 110 via liquid level sensor data cable 105. The edge of mounting plate 106 is suspended from cylindrical housing 102. Probe 104 may be a submersible liquid level sensor probe.

[0033] Preferably, the mounting plate 106 is connected to the sidewall of the cylindrical housing 102 via at least three suspension wires 107. One end of each suspension wire 107 is connected to the sidewall of the mounting plate 106, and the other end is connected to the sidewall of the cylindrical housing 102. The connection points of each suspension wire 107 are aligned on the sidewall of the cylindrical housing 102. The connection points of each suspension wire 107 are also aligned on the sidewall of the mounting plate 106.

[0034] Preferably, the data transmission cable 130 is an armored cable, which wraps the camera data line 103 and the liquid level sensor data line 105. Figure 2 The liquid level sensor data cable 105 has length redundancy, so that the part of the liquid level sensor data cable 105 not wrapped by the data transmission cable 130 is longer than the length after the camera 121 is connected to the mounting plate 106, thereby avoiding the liquid level sensor data cable 105 interfering with the suspension of the liquid level sensor 122.

[0035] Preferably, the probe 104 is involved in the center of the clamping plate 106, and the cross-sectional shape of the clamping plate 106 perpendicular to the clamping direction can be set to a circle or an equilateral polygon to facilitate suspension and leveling.

[0036] See also Figure 3 The console 110 is provided with a display screen 111 for displaying the image captured by the camera 121 and the liquid level detected by the liquid level sensor 122. The console 110 is also provided with at least three indicator lights 112 for indicating the liquid level.

[0037] See also Figure 4 Preferably, the reel 142 is provided with a handle 143. The operator can rotate the reel 142 by the handle 143 to retract or extend the data transmission cable 130. Figure 5 In another preferred embodiment, the reel 142 is connected to a motor 144. The operator can drive the reel 142 to rotate forward or reverse by the motor 144 to retract or extend the data transmission cable 130.

[0038] Preferably, the data transmission cable 130 and the cable retraction device 140 together constitute a single-line winch. The data transmission cable 130 includes a first cable and a second cable. The first cable is connected to the detector 120 at one end and to the cable retraction device 140 at the other end. The second cable is connected to the cable retraction device 140 at one end and to the control console 110 at the other end. The cable retraction device 140 is equipped with a communication converter, enabling communication between the first cable and the second cable.

[0039] The present invention combines a liquid level sensor 122 with a camera 121 to form a detector 120 for detecting pile sinking, and lowers the detector 120 through a cable retracting device 140. During the process of lowering the detector 120, the operator does not need to pay attention to the display screen 111 at all times to determine whether the detector 120 is lowered to the appropriate position. The operator can confirm whether the detector 120 is lowered into place by the indicator light 112 on the console 110.

[0040] The three indicator lights 112 include a first indicator light, a second indicator light and a third indicator light, which are used to indicate zero liquid level, a first liquid level and a second liquid level respectively.

[0041] When the level meter reading is 0, the first indicator light is on, and the second and third indicator lights are off; at this time, the detector 120 is in the process of being lowered, and the detector 120 has not yet reached the pile bottom detection position.

[0042] When the level meter reading is not 0 and does not exceed the threshold, the second indicator light turns on and the first and third indicator lights turn off; at this time, the detector 120 reaches the pile bottom detection position, and the water level at the pile bottom does not exceed the safety index, and the operator needs to check the pile bottom condition through the camera 121.

[0043] When the level meter reading exceeds the threshold, the third indicator light turns on and the first and second indicator lights turn off. At this time, the water level at the bottom of the pile exceeds the safety index and the pile bottom quality is unqualified. The operator does not need to check the pile bottom condition through the camera 121.

[0044] The utility model can confirm not only whether the detector 120 is lowered into place through the indicator light 112 on the console 110, but also whether the operator needs to check the pile bottom condition through the camera 121.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
