Description

Technical Field

[0001] The invention relates to the field of leakage detection, and in particular to a mobile anti-leakage detection device. Background Art

[0002] The long-term operation of various electrical equipment in the power distribution room is affected by environmental factors, equipment aging, overload operation and other factors, which can easily lead to problems such as loose electrical connections, reduced insulation performance, and abnormally high temperatures. If these problems are not discovered and resolved in time, they may not only cause equipment damage, but also cause serious power accidents, resulting in large-scale power outages, which will have a great negative impact on social production and life.

[0003] Manual inspection mainly relies on operation and maintenance personnel to conduct inspections based on their experience and simple tools. Since different components in the transformer box need to be inspected, and inspectors cannot carry multiple large-scale inspection equipment at one time to inspect different components, and the inspection equipment needs to be replaced manually, the efficiency is low.

[0004] In the prior art, for example, the patent with publication number CN119342179A discloses a distribution station environment monitoring device based on the Internet of Things, which installs a distribution box on the bottom plate and uses an adjustable monitoring head to monitor the distribution box and the surrounding environment. The operation method is to adjust the monitoring range by adjusting the first mounting block and the second mounting block to move the two monitoring heads, and also use the circulating rail to allow the monitoring head to monitor the environment around the distribution box; however, the device has obvious shortcomings. On the one hand, the entire device is a fixed installation mode and cannot be flexibly moved to different equipment for targeted detection, which makes it difficult to meet the complex and changeable distribution room detection needs; and the device can only detect a single distribution cabinet, so if all distribution cabinets in the distribution room need to be detected, it is necessary to install multiple devices.

[0005] Moreover, the device lacks a ground wire conductive device. During the detection process of the instrument, if the distribution cabinet leaks electricity, the current cannot be promptly introduced into the earth through the ground wire, which will cause the entire device casing to be energized, indirectly causing damage to the detection instrument 16; at the same time, continuous leakage may also cause electrical fires. Due to the lack of effective grounding protection, the electric sparks generated by the leakage can easily ignite the surrounding flammable materials, thereby causing immeasurable losses to other equipment in the distribution room and the entire distribution system.

[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing anti-leakage detection equipment. Summary of the invention

DETAILED DESCRIPTION

[0038] The following combination Figures 1 to 15 Embodiments of the present invention are described in detail.

[0039] The embodiment of the present application discloses a mobile anti-leakage detection device, which is used in the process of detecting transformer boxes and internal components. It can realize flexible mobile detection, stably provide power support, and ensure detection safety. In particular, when detecting different types of components, the detection instruments can be easily switched to meet diverse detection needs. Furthermore, the present application solves the problems of equipment movement stability during the detection process, preventing detection omissions, and avoiding damage to driving components due to current.

[0040] Example 1: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a base plate 1, a moving vehicle 10, a pulley member 2, a transformer box 11, a guide rail 12, a main cylinder 13, a circular plate 14, a cross plate 15, a placement area, a detection instrument 16, a conductive component 3, a structural groove 17 and a through groove 18. A pulley member 2 is provided at the bottom of the moving vehicle 10, and a guide rail 12 is installed on the base plate 1, which is located between the transformer boxes 11 and the upper end of which is in contact with the pulley member 2. That is, the moving vehicle 10 can move on the guide rail 12 through the pulley member 2, and the guide rail 12 can limit the moving path of the moving vehicle 10 through the pulley member 2, so that the moving vehicle 10 can move around the transformer box 11.

[0041] A main cylinder 13 is rotatably disposed in the moving vehicle 10 , and a circular plate 14 is disposed on one side of the main cylinder 13 through the outer wall of the moving vehicle 10 . The main cylinder 13 can drive the circular plate 14 to rotate when driven by an external force.

[0042] A cross plate 15 is installed at the upper end of the circular plate 14, and the circular plate 14 is divided into four placement areas by the cross plate 15. Four detection instruments 16 separated by the cross plate 15 are installed on the circular plate 14. A conductive component 3 for conducting electricity to the detection instrument 16 is arranged between the pulley parts 2. A structural groove 17 corresponding to the main cylinder 13 is opened in the middle part of the cross plate 15 and the upper and lower ends of the mobile vehicle 10. One end of the conductive component 3 extends into the structural groove 17 and is located at the upper end of the cross plate 15. Four through grooves 18 corresponding to the placement areas are opened in the middle part of the cross plate 15. The detection instrument 16 is connected to the conductive component 3 with cables through the through grooves 18. The guide rail 12 serves as a conductive medium. When the external power supply is turned on, the current is transmitted along the guide rail 12.

[0043] The pulley member 2 is in close contact with the conductive component 3. During the movement, the current on the guide rail 12 is stably transmitted to the detection instrument 16 to provide power support for the detection work.

[0044] The grounding terminal of the detection instrument 16 is also connected to the guide rail 12 by means of the conductive component 3. Since the guide rail 12 has a good conductive connection with the ground, a complete conductive circuit is formed. In this way, when an abnormal leakage occurs in the detection instrument 16, the current can be quickly conducted to the ground through the guide rail 12, effectively avoiding damage to the detection instrument 16 due to current overload or leakage, thereby greatly improving the safety and stability of the detection process.

[0045] Reference Figure 5 and Figure 6 As shown, the pulley member 2 is composed of a limiting cone 20 and a wheel 21 rotating in the corresponding limiting cone 20, and the limiting cone 20 is four symmetrically installed at the four corners of the bottom of the mobile vehicle 10. The wheel 21 can rotate on the limiting cone 20, so that the mobile vehicle 10 can move on the guide rail 12, and then drive the detection instrument 16 to detect each transformer box 11, realizing the mobile detection function of the present invention.

[0046] A conductive groove is provided on the inner bottom wall of the guide rail 12, and conductive plates 22 are provided on the inner walls on both sides of the conductive groove. A conductive ring 23 extending into the conductive groove is provided on the outer side of the wheel 21, and the conductive ring 23 is in contact with the conductive plate 22, that is, the outer side of the guide rail 12 is coated with insulating material to prevent people from touching the outer side of the guide rail 12 and getting an electric shock. The end of the conductive plate 22 is used to connect with an external power supply device and a ground wire conduction end (existing technology), so that the conductive plate 22 can conduct electricity or be used to connect with the ground wire respectively, and then the electric energy is transferred from the wheel 21 and the limit cone 20 to the conductive component 3 through the conductive plate 22, and then the electric energy is transferred to the detection instrument 16 through the cable through the conductive component 3. Similarly, the detection instrument 16 can be connected to the conductive plate 22 in reverse through the cable, the conductive component 3 and the wheel 21 to achieve the grounding effect.

[0047] Reference Figure 7 , Figure 8 and Fig. 9 As shown, it is used to connect with the conductive plate 22 to transfer electrical energy to the conductive component 3 on the detection instrument 16; specifically, the conductive component 3 includes a plate 1 30, a grounding tube 31, a grounding wire 32, a plate 2 33, a conductive rod 34, an arc groove 35 and a conductive wire 36. The plate 1 30 is arranged on two limiting cones 20 on one side, and the plate 1 30 is provided with a grounding tube 31 that passes through the main tube 13, and the plate 1 30 can support the grounding tube 31.

[0048] Four grounding wires 32 extending from the through slots 18 and connected to the detection instrument 16 are arranged on the outside of the grounding tube 31. The detection instrument 16 can be connected through the grounding wires 32, the grounding tube 31, the plate 30, the limiting cone 20, the wheel 21 and the conductive plate 22 on one side, thereby forming a complete grounding loop.

[0049] To ensure that during the operation of the detection instrument 16, if an abnormal situation such as leakage occurs, the current can be quickly introduced into the ground through the circuit to ensure the safety of the detection instrument 16 and the operator. At the same time, it can also effectively eliminate electrostatic interference, improve the accuracy and stability of the detection data, and provide reliable safety protection and a stable operating environment for the detection work of the transformer box 11.

[0050] The two limiting cones 20 on the other side are commonly provided with a second plate 33, and a conductive rod 34 extending into the grounding tube 31 is provided at the upper end of the second plate 33. Several arc grooves 35 corresponding to the through grooves 18 are provided on the outer side of the grounding tube 31, and several conductive wires 36 passing through the corresponding arc grooves 35 and the through grooves 18 and connected to the detection instrument 16 are provided on the outer side of the conductive rod 34. The second plate 33 can support the conductive rod 34, and the conductive rod 34 can indirectly transfer the current in the conductive plate 22 to the corresponding detection instrument 16 through the conductive wire 36, so that it can work. According to the above description, it can be known that the two conductive plates 22 are used for transmitting current and grounding respectively.

[0051] It should be noted that the grounding wire 32 and the conductive wire 36 are both connected to the detection instrument 16 in a detachable manner, such as being plugged into corresponding connection ports of the detection instrument 16 .

[0052] Reference Fig.10 and Fig.11 As shown, a detection unit 4 for switching different detection instruments 16 for testing is arranged at the upper end of the conductive rod 34; specifically, the detection unit 4 includes a support strip 40, an annular ring 41, a bent plate 42, an arc plate 43, a trigger plate 44, a receiving groove 45 and a contact end 5. The support strip 40 is arranged at the upper end of the conductive rod 34, and an annular ring 41 corresponding to the detection instrument 16 is arranged at the lower end of the support strip 40, that is, the conductive rod 34 can support the annular ring 41 through the support strip 40, so that the inner diameter of the annular ring 41 can correspond to the inner wall of the detection instrument 16, and when the circular plate 14 is driven by the main shaft to rotate, the annular ring 41 will not rotate due to the indirect support limit of the conductive rod 34.

[0053] A bending plate 42 is provided on one side of the detection instrument 16, and an arc plate 43 is provided on the side of the bending plate 42 away from the detection instrument 16. A trigger plate 44 with an L-shaped cross-section is provided on the inner diameter of the annular ring 41. A receiving groove 45 is provided on the outer side of the annular ring 41. A contact terminal 5 for plugging and contacting components in the transformer box 11 is provided in the receiving groove 45. The detection instrument 16 can transmit the detection signal or detection current to the contact terminal 5 through the bending plate 42, the arc plate 43, the trigger plate 44 and the rotating circle 50. When the contact terminal 5 contacts the components of the transformer box 11, the detection instrument 16 can receive accurate data.

[0054] Considering that different types of components require different types of testing instruments 16 , the four testing instruments 16 arranged in the placement area have different functions.

[0055] For example, the first is an ammeter, which is used to detect the current of components and determine whether it is within the normal operating current range; the second is a multimeter, which can measure the resistance value to help determine whether the resistance of the components meets the standards; the third is a professional filter detector, which can detect the filtering effect in the circuit and ensure signal stability; the fourth is a leakage detector, which is specifically used to detect whether there is leakage in the transformer box 11 to ensure power safety.

[0056] When it is necessary to switch to a different detection instrument 16 for detection, the driving spindle drives the circular plate 14 to rotate, and the circular plate 14 drives the detection instrument 16 to rotate, so that the arc plate 43 corresponding to the next detection instrument 16 contacts the trigger plate 44 and is indirectly connected to the contact end 5. Then the detection instrument 16 "contacts" the component through the contact end 5 to complete the detection work.

[0057] Reference Fig.12 and Fig.13 As shown, the contact end 5 is used to plug and contact the components in the transformer box 11; specifically, the contact end 5 includes a rotating circle 50, an arc groove 51, a rectangular block 52, a support plate 53, a mounting groove 54, a T-shaped guide block 55, a swing frame plate 56, a circle block 57, a spiral line 58, a limit rod 59 and a detection needle 510. The rotating circle 50 is rotatably arranged in the accommodating groove 45, that is, the rotating circle 50 can rotate in the accommodating groove 45 when driven by an external force.

[0058] An arc groove 51 is provided in the rotating circle 50, and rectangular blocks 52 are symmetrically arranged in the arc groove 51. A T-shaped groove is provided on the rectangular block 52. A support plate 53 is also inserted in the arc groove 51 in a detachable manner. A mounting groove 54 corresponding to the T-shaped groove port is provided in the support plate 53, and a T-shaped guide block 55 is inserted between the mounting groove 54 and the T-shaped groove. A swing frame plate 56 is provided on the side of the support plate 53 away from the rotating circle 50, and two circle blocks 57 corresponding to the T-shaped guide block 55 are provided at one end of the swing frame plate 56. A spiral line 58 is provided on one side of the T-shaped guide block 55, and a limiting rod 59 inserted in the corresponding circle block 57 is provided on the side of the spiral line 58 away from the T-shaped guide block 55. A detection needle 510 located outside the circle block 57 is provided on one end of the limiting rod 59 passing through the circle block 57.

[0059] When conducting the test, the tester holds the test needle 510 in his hand, and the limit rod 59 pulls out the spiral wire 58. The spiral wire 58 is an elastic spiral, and its wire body will be stretched when being pulled. Then the tester plugs the port of the test needle 510 into the component to be tested or the shell of the transformer box 11. The testing instrument 16 can indirectly detect the leakage phenomenon of the components and the shell of the transformer box 11 and whether they are damaged through the annular ring 41, the accommodating groove 45, the rotating circle 50, the arc groove 51, the rectangular block 52, the support plate 53, the installation groove 54, the T-shaped guide block 55, the swing frame plate 56, the circle block 57, the spiral wire 58, the limit rod 59 and the test needle 510.

[0060] During the detection process, if the detection position angle is relatively special, the rotating circle 50 can be driven to rotate in the accommodating groove 45 by swinging the frame plate 56 and rotating to the corresponding position, so that the detection needle 510 can extend to the detection position for detection. When the detection of the transformer boxes 11 on the corresponding sides is completed, the mobile vehicle 10 can be used to drive the device to move toward another transformer box 11, and several transformer boxes 11 can be sequentially detected. At this time, even if the operator is replaced, it can be known which transformer boxes 11 have been detected according to the parking position of the mobile vehicle 10, and the subsequent transformer boxes 11 in the forward direction of the mobile vehicle 10 can be detected.

[0061] Similarly, during the detection process, the different detection instruments 16 can be indirectly switched by rotating the driving motor 62, and at this time the detection personnel can hold the detection needle 510 all the time to continuously detect the corresponding components, thereby avoiding the detection personnel being distracted and causing missed detection.

[0062] Example 2: Reference Fig.14 As shown, on the basis of the first embodiment, in order to drive the main shaft and the wheel 21 to rotate, a driving unit 6 is provided in the mobile vehicle 10; specifically, the driving unit 6 includes a passive gear 60, a sliding block 61, a driving motor 62, a driving gear 63, a driving cylinder 64, a transmission shaft 65, a vertical shaft 66 and a transmission gear 67, the passive gear 60 is sleeved on the outer side of the main shaft located in the mobile vehicle 10, a sliding block 61 is slidingly provided on the inner wall of the mobile vehicle 10, a driving motor 62 is mounted on the sliding block 61 through a motor seat, and a driving gear 63 meshing with the passive gear 60 is sleeved on the output shaft of the driving motor 62, that is, at this time, the driving motor 62 can drive the main shaft to rotate through the cooperation of the driving gear 63 and the passive gear 60, thereby indirectly realizing the conversion between different detection instruments 16, and further, the sliding block 61 can drive the driving motor 62 to move in the left and right directions when driven by an external force, so that the driving gear 63 is no longer meshed with the passive gear 60.

[0063] A driving cylinder 64 is also provided on the inner bottom wall of the mobile vehicle 10 through a driving motor 62, and the telescopic shaft of the driving cylinder 64 is connected to the sliding block 61, that is, the driving cylinder 64 can drive the sliding block 61 to move in the left and right directions. Furthermore, a transmission shaft 65 is provided between the corresponding front and rear wheels 21 on one side, and a vertical shaft 66 is provided on the mobile vehicle 10, the first plate 30 and the second plate 33 for rotation together. The bottom of the vertical shaft 66 is connected to the two transmission shafts 65 by means of bevel gear transmission, and the vertical shaft 66 can rotate between the mobile vehicle 10, the first plate 30 and the second plate 33.

[0064] One end of the vertical shaft 66 located in the moving vehicle 10 is sleeved with a transmission gear 67, and the outer side of the transmission gear 67 corresponds to the driving gear 63, that is, when the driving motor 62 is driven by the driving cylinder 64 to be adjacent to the vertical shaft 66, the driving gear 63 will mesh with the transmission gear 67, and indirectly drive the vertical shaft 66 to rotate through the driving motor 62, and the vertical shaft 66 will drive the two transmission shafts 65 to rotate through the bevel gear transmission, so the transmission shaft 65 will drive the corresponding wheel 21 to rotate on the guide rail 12, so that the device can move.

[0065] It should be noted that the vertical shaft 66 and the transmission shaft 65 proposed in the above implementation process are made of non-conductive materials, such as plastic, to prevent the current on the wheel 21 from being indirectly transmitted to the drive motor 62 through the transmission gear 67 and the driving gear 63, causing the drive motor 62 to short-circuit and be damaged, making it unusable.

[0066] Example 3: Continue to refer to Fig.14 and Fig.15 As shown, on the basis of the first and second embodiments, in order to ensure that the wheel 21 will not be pushed and cause the mobile vehicle 10 to move when the personnel are inspected, a limiting component 7 for limiting the vertical axis 66 is provided on the telescopic shaft of the driving cylinder 64 to indirectly limit the wheel 21. Specifically, the limiting component 7 includes a limiting frame 70, a limiting groove 71 and a limiting block 72. The limiting frame 70 is arranged on the outside of the telescopic shaft of the driving cylinder 64, and the vertical axis 66 is located in the limiting frame 70. A plurality of limiting grooves 71 distributed along the axis center are provided on the outside of the vertical axis 66, and The inner wall of one side of the limit frame 70 is provided with several limit blocks 72 located in the limit groove 71. When the driving cylinder 64 indirectly drives the driving motor 62 to drive the active gear 63 to mesh with the passive gear 60, that is, at this time the transformer box 11 is to be tested, the mobile vehicle 10 cannot move. At this time, the limit frame 70 can move with the telescopic shaft of the driving cylinder 64, driving the limit block 72 to be inserted into the corresponding limit groove 71, and the vertical axis 66 is limited by the limit groove 71, which indirectly limits the wheel 21, so that the mobile vehicle 10 will not move when driven by external force.

[0067] When the sliding block 61 indirectly drives the driving gear 63 to mesh with the transmission gear 67, the driving gear 63 needs to indirectly drive the wheel 21 to rotate, and the limit frame 70 will drive the limit block 72 to no longer be inserted in the limit slot 71, and the vertical shaft 66 can continue to rotate.

[0068] During operation: the first step is to turn on the external power supply, the current is transmitted along the guide rail 12, the pulley 2 is in close contact with the conductive component 3, and the current on the guide rail 12 is stably transmitted to the detection instrument 16. At the same time, the grounding end of the detection instrument 16 is connected to the guide rail 12 with the help of the conductive component 3 to form a complete conductive circuit.

[0069] In the second step, according to the type of components to be detected, the driving motor 62 in the driving unit 6 drives the main shaft to rotate through the cooperation of the driving gear 63 and the passive gear 60, and the circular plate 14 rotates accordingly, switching to the appropriate detection instrument 16.

[0070] In the third step, the driving cylinder 64 in the driving unit 6 drives the sliding block 61 and the driving motor 62 to move, so that the driving gear 63 is meshed with the transmission gear 67, and the driving motor 62 drives the vertical shaft 66 to rotate. The vertical shaft 66 drives the transmission shaft 65 to rotate through the bevel gear transmission, thereby driving the wheel 21 to rotate on the guide rail 12, and the mobile vehicle 10 moves to the position of the transformer box 11 to be tested.

[0071] In the fourth step, the limit assembly 7 takes effect. When the driving cylinder 64 indirectly drives the driving motor 62 to drive the active gear 63 to engage with the passive gear 60, the limit frame 70 drives the limit block 72 to be inserted into the limit groove 71 of the vertical shaft 66 to limit the vertical shaft 66, indirectly limiting the rotation of the wheel 21 and preventing the mobile vehicle 10 from moving during detection.

[0072] In the fifth step, the inspector holds the inspection needle 510 of the contact end 5, pulls the limit rod 59 out from the spiral wire 58, and after stretching the spiral wire 58, plugs the port of the inspection needle 510 into the component to be inspected or the shell of the transformer box 11. The inspection instrument 16 performs leakage and damage inspection on the components and the shell of the transformer box 11 through a series of components. If the inspection position angle is special, the rotating circle 50 can be driven to rotate in the accommodating groove 45 by swinging the frame plate 56 to adjust the position of the inspection needle 510.

[0073] Step 6. After completing the inspection of the current transformer box 11, the driving cylinder 64 drives the limit frame 70 to make the limit block 72 disengage from the limit groove 71. The driving motor 62 drives the wheel 21 to rotate, and the mobile vehicle 10 moves to the next transformer box 11 to continue the inspection. The operator can know the inspection progress according to the parking position of the mobile vehicle 10.
