Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to an electromagnetic detection device and a salvage device. Background Art

[0002] At present, China's infrastructure is developing rapidly. During construction, piling is required, and in the piling work, the impact drill bit often breaks and falls into the well. Since the well is filled with mud and it cannot be pumped out (if pumped out, it is very likely to cause a landslide).

[0003] Currently, the prior art generally uses a machine device equipped with a traditional imaging device to detect metal (iron, cobalt, nickel) objects, determine the approximate shape and position of the objects to assist the next step of construction. However, for low visibility situations, accurate guidance cannot be implemented. Therefore, for low visibility situations, manual diving salvage is mostly used, and this manual salvage method is highly dangerous. Once a danger occurs, it is difficult to carry out rescue. Summary of the Invention

[0004] The purpose of the present invention is to provide an electromagnetic detection device and a salvage device to alleviate the technical problem that in the prior art, the method of using a machine device equipped with a traditional imaging device for salvage cannot achieve accurate detection and guidance in a well with low visibility.

[0005] In a first aspect, the present invention provides an electromagnetic detection device, including: a main body frame, a walking wheel set, and a scanning device;

[0006] The walking wheel set is installed on the main body frame and is used to fit against the well wall and move along the well wall;

[0007] The scanning device is slidably connected to the main body frame. The scanning device includes an electromagnetic element and a sensor. The electromagnetic element is used to collect information of the part to be salvaged and send the information to the sensor, and the sensor is used to receive the information and send the information to a control element.

[0008] Further, a plurality of the electromagnetic elements are provided, and the plurality of electromagnetic elements are integrally arranged in a matrix form;

[0009] Each of the electromagnetic elements is correspondingly provided with the sensor.

[0010] Further, the electromagnetic element uses an electromagnet;

[0011] And / or, the sensor uses a pressure sensor;

[0012] And / or, a counter for collecting the number of rotation turns thereof is provided on the walking wheel set.

[0013] Further, the main body frame includes a first cross bar, a second cross bar, and a connecting rod fixedly connected between the two;

[0014] The scanning device is slidably connected between the first cross bar and the second cross bar.

[0015] Further, both the first cross bar and the second cross bar are telescopic rods.

[0016] Further, both the first cross bar and the second cross bar include a fixed rod and a movable rod;

[0017] The fixed rod is provided with a plurality of first connection holes along the axial direction, the movable rod is provided with one or more second connection holes along the axial direction, and any one of the second connection holes can be connected to any one of the plurality of first connection holes through a fastener.

[0018] Further, the walking wheel set includes two walking wheels, one of the walking wheels is rotatably connected to the first cross bar, and the other walking wheel is rotatably connected to the second cross bar.

[0019] Further, a level sensor is provided on the main body frame;

[0020] Both the level sensor and the walking wheel set are electrically connected to the control element. The level sensor is used to collect the deflection angle information of the main body frame relative to the horizontal plane and send the deflection angle information to the control element. The control element is used to receive the deflection angle information and control the rotation angle of the walking wheel set.

[0021] Further, both ends of the axle of the walking wheel are connected with a walking frame, and the walking frame is rotatably connected to the first cross bar or the second cross bar;

[0022] A shock absorption and buffering component is provided between the axle of the walking wheel and the walking frame.

[0023] Beneficial effects:

[0024] The electromagnetic detection device provided by the present invention has a walking wheel set installed on the main frame, and the scanning device is slidably connected to the main frame. Since the walking wheel set can be attached to the well wall and move along the well wall, the scanning device can move up or down underground under the drive of the walking wheel set. At the same time, since the scanning device is slidably connected to the main frame, the scanning device can also move along the main frame to expand the scanning area of the scanning device. Since the scanning device includes an electromagnetic element and a sensor, during actual use, the magnetic field generated by the electromagnetic element will generate an attractive force on the parts to be salvaged (made of metal). According to Newton's third law, the parts to be salvaged (made of metal) being detected will also generate a reaction force on the electromagnetic element, and the sensor will reflect the force received by the corresponding electromagnetic element to the control element in the form of an electrical signal to obtain the position of the parts to be salvaged.

[0025] As can be seen from the above, the method for the electromagnetic detection device to obtain the position of the parts to be salvaged does not require manual entry into the well, and there is no special requirement for the visibility in the well, that is, the position detection of the parts to be salvaged can be achieved even in a well with low visibility. In addition, it can also reduce the risk of the salvage personnel and save the lives of engineering divers.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0044] This embodiment provides an electromagnetic detection device. Referring to Figure 1 , the electromagnetic detection device includes a main body frame 100, a walking wheel set 200 and a scanning device 300; the walking wheel set 200 is installed on the main body frame 100 and is used to fit against the wellbore wall and move along the wellbore wall; the scanning device 300 is slidably connected to the main body frame 100. The scanning device 300 includes an electromagnetic element and a sensor. The electromagnetic element is used to collect information of the part to be salvaged and send the information to the sensor, and the sensor is used to receive the information and send the information to the control element.

[0045] For the electromagnetic detection device provided in this embodiment, driven by the walking wheel set, the scanning device can move up or down in the well; at the same time, since the scanning device is slidably connected to the main body frame, the scanning device can also move along the main body frame, expanding the scanning area of the scanning device. Since the scanning device includes an electromagnetic element and a sensor, in the actual use process, the magnetic field generated by the electromagnetic element will generate an attractive force on the part to be salvaged (made of metal). According to Newton's third law, the part to be salvaged (made of metal) being detected will also generate a reaction force on the electromagnetic element, and the sensor will reflect the force received by the corresponding electromagnetic element to the control element in the form of an electrical signal to obtain the position of the part to be salvaged. The method for the electromagnetic detection device of this embodiment to obtain the position of the part to be salvaged does not require manual entry into the well, and there is no special requirement for the visibility in the well, that is, the position detection of the part to be salvaged can be realized even in a well with low visibility. In addition, it can also reduce the risk of the salvage personnel and save the lives of engineering divers.

[0046] In the actual application process, in combination with the known specifications and models of the parts to be detected and salvaged, the position and shape of the metal element can also be accurately known under low visibility.

[0047] Furthermore, a plurality of electromagnetic components are provided, and the plurality of electromagnetic components are integrally arranged in a matrix form; each of the electromagnetic components is correspondingly provided with a sensor. With such an arrangement, the scanning or detection range of the scanning device can be increased at a certain time or at a specific position, and the accuracy of the detection device can be improved.

[0048] Exemplarily, the electromagnetic components can be arranged in a 100X4000 matrix, and sensors are installed at the tails of each electromagnetic component.

[0049] All the electromagnetic components are arranged in a cluster. When there is a metal part under a certain electromagnetic component, a force acts between the electromagnetic component and the metal part, and the sensor at its tail will generate a reading. Integrating the readings of the sensors and information such as position arrangement into the control element (such as the chip of the host computer) can obtain information such as the approximate shape of the metal part directly below the scanning device.

[0050] In this embodiment, the electromagnetic component can be an electromagnet. Specifically, the magnetic field generated by the electromagnet will generate an attractive force on the part to be salvaged. According to Newton's third law, the part to be salvaged being detected will generate a reaction force on the electromagnet, and the force received by the corresponding electromagnet will be reflected to the control element in the form of an electrical signal through the sensor.

[0051] Optionally, the sensor is a pressure sensor; when the electromagnet does not sense the part to be salvaged, the signal collected by the pressure sensor corresponding to the sensor can be "0"; when the electromagnet senses the part to be salvaged, the signal collected by the pressure sensor corresponding to the sensor is not "0", that is, greater than "0".

[0052] In this embodiment, a counter for collecting the number of rotations of the traveling wheel set 200 is provided on the traveling wheel set 200. The counter can be electrically connected to the control element. The counter is used to detect the number of rotations of the traveling wheel set 200 and send the number of rotations to the control element to obtain the depth of the detection device in the well, that is, the descending depth, and initially obtain the position of the part to be salvaged.

[0053] Furthermore, referring to Figure 2 , the main frame 100 includes a first cross bar 110, a second cross bar 120, and a connecting rod 130 fixedly connected between the two; the scanning device 300 is slidably connected between the first cross bar 110 and the second cross bar 120. With such an arrangement, not only can the stability and smoothness of the main frame 100 be ensured, but also the structure is relatively simple, facilitating the installation of the scanning device 300, etc.

[0054] Specifically, the main frame 100 is generally in an "H" shape. The scanning device 300 is installed on the slide rail of the "H"-shaped main frame 100. Horizontally, it is driven by a high-precision servo motor so that the main frame 100 can slide on the slide rail. After outputting information at one position, it is driven by the motor to transfer to the next detection position, and continue to output signals at the next position. According to this process, the area directly below the entire scanning device frame can be scanned and imaged.

[0055] In this embodiment, both the first cross bar 110 and the second cross bar 120 are telescopic rods. With such a setting, the lengths of the first cross bar 110 and the second cross bar 120 can be adjusted according to the size of the well, so that the traveling wheel set 200 can better fit the well wall. During construction, different models of the main frame 100 can be selected for installation according to different usage environments, so as to detect underwater metal parts more comprehensively and accurately.

[0056] Specifically, referring to Figure 3 , both the first cross bar 110 and the second cross bar 120 include a fixed rod and a movable rod; the fixed rod is provided with a plurality of first connection holes along the axial direction, and the movable rod is provided with one or more second connection holes along the axial direction. The second connection hole can be connected to any one of the plurality of first connection holes through a fastener.

[0057] Please continue to refer to Figure 3 , the first cross bar 110 includes a first fixed rod 111 and a first movable rod 112; the second cross bar 120 includes a second fixed rod 121 and a second movable rod 122.

[0058] In other embodiments, both the first cross bar 110 and the second cross bar 120 are fixed rods. With such a setting, it can be adapted to the detection work with a fixed well size.

[0059] On the basis of the above embodiments, referring to Figure 2 and Figure 3 , the traveling wheel set 200 includes two traveling wheels 210. One of the traveling wheels 210 is rotatably connected to the first cross bar 110, and the other traveling wheel 210 is rotatably connected to the second cross bar 120.

[0060] Furthermore, a horizontal sensor (not shown in the drawings) is provided on the main frame 100; both the horizontal sensor and the traveling wheel set 200 are electrically connected to the control element. The horizontal sensor is used to collect the deflection angle information of the main frame 100 relative to the horizontal plane, and send the deflection angle information to the control element. The control element is used to receive the deflection angle information and control the rotation angle of the traveling wheel set 200.

[0061] After the detection device is placed in the downhole mud, the level of the detection surface can be finely adjusted by adjusting the traveling wheels 210 at the end of the main frame 100 according to the level sensor installed on the main frame 100, so as to achieve a more accurate detection purpose for metal parts. In addition, with such a setting, the entire detection device also has a certain obstacle avoidance ability during downhole detection. If there are obstacles on the lowering path of the detection device, the detection device can rotate in the horizontal plane through the traveling wheels 210, which can avoid obstacles to a certain extent and improve the efficiency of the detection construction.

[0062] It should be noted that since the length of the "H"-shaped main frame 100 is telescopically adjustable, when installing the detection device, the length of the main frame 100 can be adjusted according to the environment where the detection device is lowered, so that the traveling wheels 210 at the end of the main frame 100 are in contact with the wall surface of the well pit. After the contact, the position of the detection device can be adjusted by the rotation of the traveling wheels 210 and the detection device can be kept level according to the data fed back by the level sensor. At the same time, the traveling wheels 210 can rotate radially along the axis, so as to realize the rotation of the detection device in the plane. The rotation in the plane can greatly increase the scanning area of the detection device and improve the device efficiency.

[0063] Please continue to refer to Figure 3 , both ends of the axle 220 of the traveling wheel 210 are connected with a traveling frame 230, and the traveling frame 230 is rotatably connected to the first cross bar 110 or the second cross bar 120; a shock absorption and buffering component is arranged between the axle 220 of the traveling wheel 210 and the traveling frame 230. With such a setting, it can play a role of buffering and shock absorption for the main frame 100, reducing or even avoiding the damage to the main frame 100 caused by excessive impact force.

[0064] This embodiment also provides a fishing device, which includes the aforementioned electromagnetic detection device. The fishing device provided in this embodiment includes the aforementioned electromagnetic detection device. Therefore, the technical advantages and effects that the fishing device can achieve also include the technical advantages and effects that the electromagnetic detection device can achieve, which will not be elaborated here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
