[0014] According to some embodiments of this application, a sheath is provided between the second through hole and the cable.

[0015] According to some embodiments of this application, a limiting member is provided on the cable. The limiting member is located in the cavity. The size of the cavity gradually decreases along the direction from the middle of the cavity to the top of the cavity, so that when the limiting member moves towards the top of the cavity, it is limited between the middle of the cavity and the top of the cavity.

[0040] The following reference Figures 1 to 2 This application describes a piping detection probe and piping detection device according to embodiments of the present application.

[0041] This application provides a piping detection probe, such as... Figure 1 As shown, it includes:

[0042] The outer shell, along the direction from the first end of the outer shell to the second end of the outer shell, the size of the outer shell gradually increases and then gradually decreases, and the first end of the outer shell is provided with a counterweight 13;

[0043] Circuit board unit 7, wherein the circuit board unit 7 is disposed within the housing;

[0044] Cable 1, the first end of which is electrically connected to the circuit board unit 7, and the second end of which extends from the first end of the housing and is electrically connected to the host computer;

[0045] A piping detection unit is disposed on the housing and electrically connected to the circuit board unit 7. The piping detection unit is used to detect piping.

[0046] In this embodiment, since a counterweight 13 is provided at the first end of the outer shell, the center of gravity of the piping detection probe is close to the bottom of the piping detection probe. The piping detection probe remains perpendicular to the bottom of the water. Along the direction from the first end to the second end of the outer shell, the size of the outer shell gradually increases and then gradually decreases, which can reduce the change in lateral force caused by water resistance during dragging. The piping detection probe is not easy to deviate from the direction perpendicular to the bottom of the water, has good stability, and improves the accuracy of piping detection.

[0047] In some embodiments of this application, the first end of the housing is the bottom end, and the second end of the housing is the top end. A status indicator light is installed on the top end of the housing. Cable 1 is a zero-buoyancy cable.

[0048] In some embodiments of this application, such as Figure 1 As shown, the outer shell is cylindrical in shape. Along the direction from the first end to the second end of the outer shell, the size of the outer shell gradually increases and then gradually decreases, that is, the surface of the outer shell is streamlined.

[0049] In some embodiments of this application, such as Figure 1 As shown, the housing includes:

[0050] The housing 8 has a circuit board unit 7 disposed inside it. A water depth and water pressure detection unit 16 is disposed on the top of the housing 8 and is electrically connected to the circuit board unit 7.

[0051] The cover 4 has its bottom fixedly connected to the top of the housing 8 to form a cavity, and the side wall of the cover 4 is provided with at least one first through hole.

[0052] In this embodiment, the bottom of the cover 4 is fixed to the top of the housing 8 by screws and bolts. When the piping detection probe is working underwater, the cavity is connected to the external water body through the first through hole, and water flows into the cavity through the first through hole. The water depth and pressure detection unit 16 on the top of the housing 8 detects the water depth and pressure and feeds back the water depth and pressure information to the host computer. The water depth and pressure detection unit 16 is located on the top of the housing 8 and inside the cavity, which can prevent underwater debris and obstacles from getting entangled.

[0053] In some embodiments of this application, the interior of the housing 8 is completely sealed with sealant, which serves to provide waterproofing, insulation, and heat dissipation.

[0054] In some embodiments of this application, the water depth and water pressure detection unit 16 may employ sensors that detect water depth and water pressure.

[0055] In some embodiments of this application, such as Figure 1As shown, a waterproof connector 5 is provided on the top of the housing 8, and the first end of the waterproof connector 5 is electrically connected to the circuit board unit 7;

[0056] The top of the cover 4 is provided with a second through hole, the first end of the cable 1 is electrically connected to the second end of the waterproof connector 5, and the second end of the cable 1 extends out from the second through hole.

[0057] In this embodiment, the top of the housing 8 is provided with a mounting hole, and the waterproof connector 5 is installed in the mounting hole. The first end of the waterproof connector 5 is electrically connected to the circuit board unit 7 inside the housing 8, and the second end of the waterproof connector 5 is connected to the first end of the cable 1, thereby making the cable 1 electrically connected to the circuit board unit 7. The second end of the cable 1 extends out from the second through hole and is electrically connected to the host computer.

[0058] In some embodiments of this application, such as Figure 1 As shown, a sheath 2 is provided between the second through hole and the cable 1.

[0059] In this embodiment, the sheath 2 protects the cable 1 from mechanical damage, and the sheath 2 can also fill the gap between the second through hole and the cable 1.

[0060] In some embodiments of this application, a limiting member 3 is provided on the cable 1. The limiting member 3 is located in the cavity. The size of the cavity gradually decreases along the direction from the middle of the cavity to the top of the cavity, so that when the limiting member 3 moves towards the top of the cavity, it is limited between the middle of the cavity and the top of the cavity.

[0061] In this embodiment, when the piping detection probe is working, cable 1 needs to be dragged. When cable 1 is dragged, the limiting member 3 moves towards the top of the cavity. As the size of the cavity gradually decreases, the limiting member 3 will be stuck between the middle and the top of the cavity. When the limiting member 3 is stuck, the tension on cable 1 due to dragging will be transmitted to the limiting member 3 and the outer shell, and will not be transmitted to the first end of cable 1, thus preventing the first end of cable 1 from being moved by force and becoming loose from the second end of the waterproof connector 5.

[0062] In some embodiments of this application, when the limiting member 3 is locked, the portion of the cable 1 between the limiting member 3 and the waterproof connector 5 is long enough to allow that portion of the cable 1 to be in a slack state.

[0063] In some embodiments of this application, such as Figure 2 As shown, the limiting member 3 includes:

[0064] The column 31, the cable 1 is wound around the column 31, and the column 31 is provided with a third through hole;

[0065] A first clamping member 32 and a second clamping member 33 are respectively disposed on both sides of the column 31. The first clamping member 32 is fixedly connected to the second clamping member 33 for fixing the cable 1 on the column 31. The inner wall of the first clamping member 32 is provided with a first insertion hole, and the inner wall of the second clamping member 33 is provided with a second insertion hole. The first insertion hole and the second insertion hole correspond to each other.

[0066] A pin 34, one end of which is inserted into the first socket, and the other end of which passes through the third through hole and is inserted into the second socket.

[0067] In this embodiment, the pin 34 passes through the third through hole of the column 31, one end of the pin 34 is inserted into the first insertion hole on the first clamping member 32, and the other end of the pin 34 is inserted into the second insertion hole on the second clamping member 33, so that the column 31 is fixed between the first clamping member 32 and the second clamping member 33. The first clamping member 32 and the second clamping member 33 are connected to each other by screws, thereby clamping the cable 1 wrapped on the column 31. The cable 1 will not cause the column 31 to rotate due to dragging, nor will it unwrap.

[0068] In one embodiment of this application, the piping detection unit includes:

[0069] The three-component surge current abnormal field measurement metal sub-unit is electrically connected to the circuit board unit 7.

[0070] In this embodiment, a three-component surge current anomaly field measurement metal subunit receives the current signal in the water. This current signal is used to analyze whether a surge exists in the water, thereby achieving the purpose of surge detection. Compared with the single-component detection method, this greatly improves the detection accuracy.

[0071] In one embodiment of this application, the transmitter forms a current loop through the aluminum sheet electrodes on the water-facing side and the water outlet, and emits a pseudo-random current signal into the water area. The current signal in the water is sensed by the metal sub-unit of the three-component surge current anomaly field measurement.

[0072] In some embodiments of this application, such as Figure 1 As shown, the three-component surge current abnormal field measurement metal subunit includes:

[0073] Two first-component surge current abnormal field measuring metal plates 9 are installed in the middle of the housing and are electrically connected to the circuit board unit 7.

[0074] Two second-component surge current abnormal field measuring metal plates 10 are installed in the middle of the housing and are electrically connected to the circuit board unit 7.

[0075] Two third-component surge current abnormal field measuring metal plates 6 are respectively installed at the first end and the second end of the housing, and both third-component surge current abnormal field measuring metal plates 6 are electrically connected to the circuit board unit 7.

[0076] In this embodiment, the first component surge current anomaly field measuring metal plate 9 is an X-component surge current anomaly field measuring metal plate, the second component surge current anomaly field measuring metal plate 10 is a Y-component surge current anomaly field measuring metal plate, and the third component surge current anomaly field measuring metal plate 6 is a Z-component surge current anomaly field measuring metal plate. The large electrode spacing between the two Z-component surge current anomaly field measuring metal plates results in higher sensitivity for measuring the critical vertical electric field.

[0077] In some embodiments of this application, two first component surge current abnormal field measuring metal plates 9 are installed at the front and rear ends of the middle of the housing, and a second component surge current abnormal field measuring metal plate 10 is installed at the left and right ends of the middle of the housing.

[0078] In some embodiments of this application, the third component surge current abnormal field measuring metal plate 6 at the first end of the housing is connected to a copper stud 62 through a copper screw 63, thereby mounting it on the housing. The copper stud 62 is electrically connected to the circuit board unit 7 through the acquisition signal line inside the housing, which solves the waterproof sealing problem and facilitates installation and disassembly. Similarly, as Figure 2 As shown, the first component surge current abnormal field measuring metal plate 9 and the second component surge current abnormal field measuring metal plate 10 are also connected to the copper stud 62 by copper screws 63 passing through the outer shell, so as to achieve electrical connection with the circuit board unit 7. The counterweight 13 is provided with a through fourth hole from bottom to top to facilitate wiring.

[0079] In some embodiments of this application, such as Figure 1 As shown, it also includes:

[0080] Distance detection unit 15 is disposed at the first end of the housing and is electrically connected to the circuit board unit 7.

[0081] In this embodiment, the distance detection unit 15 detects the distance between the first end of the outer casing and the bottom of the water to prevent the piping detection probe from touching the bottom when controlling the cable 1's reeling in and out. The distance detection unit 15 can be an ultrasonic ranging sensor.

[0082] In addition, embodiments of this application provide a piping detection device, including the piping detection probe as described above.

[0083] The piping detection device provided in this application embodiment can realize the various processes implemented in the above circuit embodiment and achieve the same beneficial effects. To avoid repetition, it will not be described again here.

[0084] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
