Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment maintenance and detection, in particular to an automatic leakage detection device. Background Art

[0002] When electrical equipment is in use, in addition to the necessary leakage protection, staff are also required to conduct manual inspections in daily or special circumstances. When staff conduct simple inspections on the equipment, they generally use a test pen or testing equipment to inspect the electrical equipment to ensure the safety of the electrical equipment.

[0003] Dust explosions are a risk factor in leakage current detection, seriously impacting the safety of electrical inspectors. The physical conditions for a dust explosion include combustible dust, oxygen, an ignition source, and a confined space. Electrical equipment maintenance personnel may encounter environments that meet dust explosion conditions during routine leakage current detection and special electrical testing. For example, when conducting leakage current detection in a distribution room that has not been cleaned for a long time, electrical equipment may be covered in dust. If leakage current is present, contact between the detection equipment and the equipment could produce sparks, leading to dust explosions or ignition. Another example is leakage current detection in distribution rooms or substations damaged by earthquakes, fires, or other disasters. Due to the large amount of dust in the room, the leakage current detection equipment is also likely to produce sparks during detection, potentially causing dust explosions.

[0004] Therefore, developing a device that can remotely complete leakage detection is extremely important for protecting the lives of power workers. Utility Model Content

[0005] In view of this, the present invention provides an automatic leakage detection device to meet the technical requirements proposed by the background technology.

[0006] To achieve the above purpose, the technical solution of this utility model is as follows:

[0007] An automatic leakage detection device, the key of which is: it includes a mobile carrier, on which a column is installed through a linear module, the linear module can drive the column to reciprocate along the length direction of the mobile carrier, the upper end of the column is installed with a swing arm that can rotate in a vertical plane and a rotary drive mechanism that drives the swing arm to rotate, the far end of the swing arm is provided with a spring extending outward, the end of the spring is connected to a leakage detector, and the far end of the swing arm is installed with a camera assembly; the mobile carrier, linear module and rotary drive mechanism can all be remotely controlled.

[0008] Preferably, the device further comprises a remote control terminal, the remote control terminal being provided with a first button group for controlling the movement of the mobile carrier, a second button group for controlling the reciprocating movement of the linear module, and a third button group for controlling the rotation of the rotary drive mechanism. The remote control terminal is provided with a display screen associated with the camera assembly.

[0009] Preferably, the leakage detector is an electric pen, and the spring is a cylindrical spring, one end of which is fixedly connected to the distal end of the swing arm, and the tail end of the electric pen is fixedly sleeved within the end of the cylindrical spring distal from the swing arm. The electric pen is provided with a pen tip probe, an indicator light, and a metal tail cap in order from front to back, and the camera assembly's imaging range covers at least the pen tip probe and the indicator light.

[0010] Preferably, the linear module is a pulley mechanism, and the lower end of the column is connected to the rotating belt of the pulley mechanism through a connecting seat.

[0011] Preferably, one end of the swing arm is rotatably mounted on the upper end of the column via a rotating shaft; the rotation drive mechanism includes a motor, a small gear fixedly mounted on the output shaft of the motor, and a large gear fixedly mounted on the rotating shaft, and the small gear is meshed with the large gear.

[0012] The beneficial effects of the utility model are:

[0013] 1. The automatic leakage detection device provided by the present invention is placed in the workplace where leakage detection is to be performed. The operator can remotely control the mobile carrier to the vicinity of the device to be tested through a remote control terminal. Subsequently, through the coordinated control of the linear module and the rotary drive mechanism, the leakage detector can be kept in contact with the device to be tested.

[0014] 2. The leakage detector is installed at the end of the swing arm through a spring. When the operator remotely controls the leakage detector to contact the surface of the device under test, the spring can automatically collapse under pressure to avoid rigid collision between the leakage detector and the surface of the device under test, thereby ensuring that the operator can more easily remotely control the leakage detector to gently contact the surface of the device under test.

[0015] 3. The horizontal reciprocating motion of the column and the rotation of the swing arm can drive the leakage detector to move nearby, enabling the leakage detector to cover any position in the space, with the technical advantage of flexible detection and use.

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0023] like Figure 1 As shown, an automated leakage detection device primarily comprises a mobile carrier 1, a column 3, a swing arm 4, a spring 6, a leakage detector 7, and a camera assembly 8. The mobile carrier 1 is a remote-controlled vehicle. The column 3 is vertically mounted on the mobile carrier 1, its lower end connected to the mobile carrier 1 via a linear module 2. The linear module 2 controls the reciprocating motion of the column 3 along the length of the mobile carrier 1. One end of the swing arm 4 is pivotally connected to the upper end of the column 3. A rotary drive mechanism 5 is also mounted on one side of the upper portion of the column 3 to drive the swing arm 4. The rotational centerline of the swing arm 4 is arranged horizontally. When the rotary drive mechanism 5 is activated, the swing arm 4 can rotate within a vertical plane. The leakage detector 7 is mounted via a spring 6 at the end of the swing arm 4 away from the column 3. Specifically, the spring 6 is mounted at the end of the swing arm 4, and the leakage detector 7 is mounted at the end of the spring 6. The camera assembly 8 is also mounted at the end of the swing arm away from the column 3.

[0024] Please refer to the attached Figure 2The detection device is equipped with a remote control terminal A, which is equipped with a first button group a for controlling the movement of the mobile carrier 1, a second button group b for controlling the reciprocating movement of the linear module 2, and a third button group c for controlling the rotation of the rotary drive mechanism 5. After placing the automatic leakage detection device at the workplace to be detected, the staff can use the remote control terminal A to remotely control the mobile carrier 1 to move to the vicinity of the device to be tested. Subsequently, through the coordinated control of the linear module 2 and the rotary drive mechanism 5, the leakage detector 7 can be brought into contact with the device to be tested. Finally, the camera component 8 can be used to remotely detect whether the corresponding device has leakage, thereby avoiding the need for power workers to enter the detection environment. Even if an explosion or deflagration occurs during the leakage detection, the safety of the power workers will not be affected. In order to more visually observe the leakage situation, a display screen d associated with the camera component 8 can also be integrated into the remote control terminal A.

[0025] like Figure 5 As shown, in this embodiment, the linear module 2 is an electrically controlled pulley mechanism, consisting of a rotating belt 2a and a belt motor 2b that drives the rotating belt 2a. The lower end of the column 3 is provided with a transfer seat 3a, which is slidably mounted along the length of the mobile carrier 1 and connected to the rotating belt 2a of the pulley mechanism. Based on this, the belt motor 2b drives the rotating belt 2a forward and reverse, thereby controlling the reciprocating motion of the column 3. Figure 6 As shown, one end of the swing arm 4 is rotatably mounted on the upper end of the column 3 via a rotating shaft 4a, and the rotary drive mechanism 5 includes a motor 5a, a small gear 5b fixed on the output shaft of the motor 5a, and a large gear 5c fixed on the rotating shaft 4a, and the small gear 5b is engaged with the large gear 5c. Based on this, the operation of the motor 5a can drive the swing arm 4 to swing and rotate. The horizontal reciprocating motion of the column 3 and the rotation of the swing arm 4 can both drive the leakage detector 7 to move, and such a control method can enable the leakage detector 7 to cover any position in the space, with the technical advantage of flexible detection and use. In addition, the leakage detector 7 is mounted on the end of the swing arm 4 by a spring 6. The spring 6 can absorb the collision force and can avoid the leakage detector 7 from rigidly colliding with the surface of the device to be tested, thereby ensuring that remote control can more easily achieve contact between the leakage detector 7 and the surface of the device to be tested.

[0026] In this embodiment, the transmission ratio between the small gear 5b and the large gear 5c in the rotary drive mechanism 5 is greater than 1, and is preferably set to 2.5. Such a design can form a reduction transmission, which helps to accurately control the rotation of the swing arm.

[0027] In this embodiment, please refer to the attached Figure 4Spring 6 is a cylindrical spring, one end of which is fixedly attached to the distal end of swing arm 4. The leakage detector 7 is an electric pen. The pen is equipped with, from front to back, a tip probe 7a, an indicator light 7b, and a metal tail cap 7c. The tail end of the pen is securely mounted within the end of the cylindrical spring facing away from the swing arm 4. The operator first rotates the swing arm 4 until the pen's tip probe 7a is aligned with the device under test 9. Then, the operator moves the column 3 so that the tip probe 7a gently strikes the surface of the device under test 9 to establish contact. To ensure proper operation of the electric pen, a ground wire e is connected to the metal tail cap 7c. This ground wire e is fixed to the swing arm 4 and column 3, with the other end of the ground wire e freely dropping to the ground. This ensures that when the pen's tip probe 7a contacts the metal surface of the device, an indicator light indicates whether there is leakage. There are many different types of electric pens available on the market, and any commercially available one can be used.

[0028] When operating the electric pen to contact the surface of the device 9, it can be completed under the guidance of the camera assembly 8 and the display screen d. To achieve this purpose, the shooting range of the camera assembly 8 must at least cover the pen tip probe 7a and the indicator light 7b.

[0029] Ginseng and Atractylodes Figure 4 For ease of installation, camera assembly 8 includes a bracket 8a fixedly mounted on the upper side of the end of swing arm 4. A camera 8b is provided on the side of bracket 8a, facing the pen tip probe 7a and indicator light 7b. An LED light can also be provided on the side of bracket 8a to facilitate detection in dark environments.

[0030] In this embodiment, remote sensing between the remote control terminal A and the mobile carrier 1, linear module 2, and rotary drive mechanism 5 is achieved via a wireless transmission module. Remotely controlling the mobile carrier 1, linear module 2, and rotary drive mechanism 5 via a wireless transmission module is a mature technology in the field of industrial automation and will not be discussed in detail here.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
