Description

Technical Field

[0001] This invention relates to the field of substation secondary equipment monitoring, and more specifically to a secondary equipment reliability monitoring device for complex substation environments. Background Technology

[0002] Traditional secondary equipment reliability monitoring is done manually, which is time-consuming and increases the workload of staff.

[0003] In the current technology, with the popularization of robots, the use of ground reliability monitoring robots to replace manual inspections is becoming increasingly common. However, due to the complex environment of substations, ground reliability monitoring robots on the market are prone to falling over, which affects normal operation. Summary of the Invention

[0004] The purpose of this invention is to provide a secondary equipment reliability monitoring device for complex substation environments, in order to solve the problem that reliability monitoring devices are prone to tipping over.

[0005] To achieve the above objectives, the present invention provides a secondary equipment reliability monitoring device for complex environments in substations, comprising a base, a support mechanism mounted on the base, a monitoring component, and a control component. The support mechanism includes support rods installed on both sides of the base and extending vertically, an auxiliary rod retractably mounted at the lower end of the support rods, and a telescopic drive component mounted on the base. The control component can detect whether the base is in a lateral tilt state. When the base is in a lateral tilt state, the control component controls the telescopic drive component to drive the support rod on the side with the lower relative height to rotate around the longitudinal axis, and the auxiliary rod extends downward relative to the support rod to support the bearing surface, thereby driving the base back to a lateral equilibrium state.

[0006] In some embodiments, the secondary equipment reliability monitoring device includes a first transmission assembly, and the telescopic drive member can drive the auxiliary rod to extend through the first transmission assembly.

[0007] In some embodiments, the first transmission assembly includes a connecting plate connected to the telescopic drive member, a first rack extending laterally and connected to the connecting plate, a first take-up roller rotatably disposed on the base, a first gear coaxially connected to the first take-up roller and meshing with the first rack, and a first connecting rope with its two ends respectively connected to the first take-up roller and the auxiliary rod. The telescopic drive member can drive the connecting plate and the first rack to move laterally, thereby causing the first take-up roller to retract or release the first connecting rope, so that the auxiliary rod retracts or extends.

[0008] In some embodiments, a first elastic element is provided between the auxiliary rod and the support rod, the first elastic element being capable of driving the auxiliary rod to extend outward.

[0009] In some embodiments, a fixed pulley is provided in the support rod, and the first connecting rope passes around the fixed pulley.

[0010] In some embodiments, the upper part of the support rod is provided with a guide groove extending along its length, the telescopic drive is connected to a mounting block, and the mounting block is provided with a sliding rod that is inserted into the guide groove.

[0011] In some embodiments, the control component includes grooves respectively disposed on both lateral sides of the base, a rolling element disposed in the grooves, and a pressure sensor. The grooves extend laterally at an angle and have a higher end and a lower end. The pressure sensor is disposed at the higher end. In a laterally balanced state, the rolling element is located at the lower end. In a laterally tilted state, the rolling element on the side of the base with a relatively lower height rolls to the higher end to trigger the pressure sensor.

[0012] In some embodiments, the lower end is provided with a fourth elastic element and a sliding plate, the fourth elastic element being located between the sliding plate and the base.

[0013] In some embodiments, the groove is formed in an arc shape.

[0014] In some embodiments, the secondary equipment reliability monitoring device includes an installation mechanism and a second transmission assembly. The installation mechanism includes a mounting plate connected to the base, a mounting seat disposed on the mounting plate, a sliding column slidably disposed on the mounting seat in a vertical direction, and a protective cover connected to the sliding column. The monitoring element is disposed on the mounting seat. The rotation of the upper end of the support rod can drive the sliding column to move downward through the transmission assembly, thereby causing the protective cover to cover the monitoring element.

[0015] In some embodiments, the second transmission assembly includes a second rack extending laterally corresponding to each of the two support rods, a push plate connected to the second rack, a second take-up roller rotatably mounted on the mounting plate, a second gear coaxially connected to the second take-up roller, a second connecting rope with its two ends connected to the second take-up roller and the sliding column respectively, and a second elastic element disposed between the mounting base and the sliding column. The support rods are capable of pushing the push plate toward the second gear, so that the rack pushes the second gear and the second take-up roller to rotate, thereby retracting the second connecting rope to drive the sliding column and the protective cover to descend.

[0016] In some embodiments, the second transmission assembly includes a third elastic element disposed between the push plate and the mounting plate.

[0017] In some embodiments, the telescopic drive component is a hydraulic cylinder.

[0018] In some embodiments, the secondary equipment reliability monitoring device includes two monitoring elements symmetrically arranged in the lateral direction.

[0019] In some embodiments, the base includes a moving mechanism.

[0020] Through the above technical solution, the control component can detect whether the base is tilted. When the base is tilted, it can control the support rod to rotate outward and extend the auxiliary rod to support the ground and obtain a reaction force. The reaction force makes the base return to the equilibrium state, ensuring the safe operation of the device. Attached Figure Description

Detailed Implementation

[0029] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] In this invention, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the relative positions when the reliability monitoring device is in normal use.

[0031] This invention provides a secondary equipment reliability monitoring device for complex environments in substations. The device includes a base 10, a support mechanism 20 mounted on the base 10, a monitoring component 50, and a control component 70. The support mechanism 20 includes support rods 21 mounted on both sides of the base 10 and extending vertically, an auxiliary rod 26 retractably mounted at the lower end of the support rods 21, and a telescopic drive component 22 mounted on the base 10. The control component 70 can detect whether the base 10 is in a lateral tilt state. When the base 10 is in a lateral tilt state, the control component 70 controls the telescopic drive component 22 to drive the support rod 21 on the side with the lower relative height to rotate around the longitudinal axis, and the auxiliary rod 26 extends downward relative to the support rod 21 to support the bearing surface, thereby driving the base 10 back to a lateral equilibrium state.

[0032] The monitoring component 50 is used to monitor surrounding secondary equipment, which can be a camera or other detection sensors, such as humidity and temperature sensors.

[0033] The horizontal direction of the base 10 refers to the horizontal direction perpendicular to its forward and backward directions, or it can also be called the left and right direction.

[0034] During use, due to obstacles on the ground (or other supporting surfaces), the base 10 may tilt in the lateral direction, i.e., be in a lateral tilted state. At this time, the height of one side of the lateral side is lower than the height of the other side.

[0035] The control component 70 can detect whether the base 10 is in a lateral tilt state, and then use the support mechanism 20 to make the base 10 return to a lateral balance state (i.e., the height of both sides is consistent).

[0036] The control component 70 may include a controller and sensors mounted on the base to detect whether the base 10 is in a lateral tilt state, such as by using an accelerometer to sense changes in height on both sides. The sensors can transmit the detected signals to the controller, which then determines whether the support mechanism 20 needs to be activated based on this information.

[0037] The support mechanism 20 includes two support rods 21 on both sides. The support rods 21 are rotatably connected to the base 10, with the axis of rotation being a longitudinal direction perpendicular to the lateral direction, i.e., the front-to-back direction. When in a lateral tilted state, the lower end of the support rod 21 (located on the lateral side of the base 10 with a lower height) can be driven outward (left side to the left, right side to the right) by the telescopic drive member 22. The auxiliary rod 26 also extends outward from the lower end of the support rod 21 to extend the overall length of the support rod 21 and the auxiliary rod 26. When the auxiliary rod 26 collides with the ground or support surface, it is subjected to a reaction force, thereby causing the base 10 to return to a lateral equilibrium state.

[0038] The auxiliary rod 26 can be driven by the telescopic drive component 22 or by another drive component.

[0039] After the control component 70 detects that the base 10 has returned to the horizontal balance state, it can control the support mechanism 20 to reset, and the support rod 21 to return to the vertical extension state.

[0040] In this solution, the control component can detect whether the base is tilted. When the base is tilted, it can control the support rod to rotate outward and extend the auxiliary rod to support the ground and obtain a reaction force. The reaction force makes the base return to the equilibrium state, ensuring the safe operation of the inspection device.

[0041] The secondary equipment reliability monitoring device includes a first transmission assembly 30, through which the telescopic drive member 22 can drive the auxiliary rod 26 to extend. The power source for the extension and retraction of the auxiliary rod 26 is the telescopic drive member 22, and the transmission between the telescopic drive member 22 and the auxiliary rod 26 is realized through the first transmission assembly. The first transmission assembly 30 can be mounted on the base 10.

[0042] Specifically, the first transmission assembly 30 includes a connecting plate 37 connected to the telescopic drive member 22, a first rack 34 extending laterally and connected to the connecting plate 37, a first take-up roller 31 rotatably mounted on the base 10, a first gear 33 coaxially connected to the first take-up roller 31 and meshing with the first rack 34, and a first connecting rope 32 with its two ends respectively connected to the first take-up roller 31 and the auxiliary rod 26. The telescopic drive member 22 can drive the connecting plate 37 and the first rack 34 to move laterally, thereby causing the first take-up roller 31 to retract or release the first connecting rope 32, so that the auxiliary rod 26 retracts or extends. (Reference) Figure 2 and Figure 3 As shown, the first take-up roller 31 is rotatably mounted on the base 10, with its axis in the longitudinal direction. A first connecting rope 32 is connected to it, and the other end of the first connecting rope 32 is connected to the auxiliary rod 26. The first take-up roller 31 is coaxially connected to a first gear 33, and a connecting plate 37 is connected to the movable part of the telescopic drive member 22, thereby driving the first rack 34 to move laterally, which in turn drives the first gear 33 and the first take-up roller 31 to rotate, so as to retract and release the first connecting rope 32. Specifically, for the left side of the base 10, when the telescopic drive member 22 on the left side extends outward, it can drive the support rod 21 to rotate outward, and at the same time drive the connecting plate 37 and the first rack 34 to move outward. The first take-up roller 31 releases the first connecting rope 32, so that the auxiliary rod 26 can extend. Conversely, when the telescopic drive member 22 retracts, the support rod 21 rotates inward, and the auxiliary rod 26 also retracts.

[0043] Additionally, a first elastic element 36 is provided between the auxiliary rod 26 and the support rod 21. This first elastic element 36 can drive the auxiliary rod 26 to extend outwards. When the auxiliary rod 26 extends outwards, the first elastic element 36 applies an elastic force to it, resulting in a greater extension speed and a stronger impact on the support surface, thus generating a greater reaction force and returning the base 10 to its equilibrium position. The auxiliary rod 26 is partially housed in the lower end of the support rod 21, and the first elastic element 36, which can be a spring or elastic rubber, is provided between its upper end and the support rod 21.

[0044] In addition, a fixed pulley 35 is provided in the support rod 21, and the first connecting rope 32 passes around the fixed pulley 35. Figure 3 In the middle, the support rod 21 is provided with a cavity to accommodate the fixed pulley 35, and has a through hole located between the fixed pulley 35 and the auxiliary rod 26 to accommodate the passage of the first connecting rope 32.

[0045] The support rod 21 has a guide groove 25 extending along its length at its upper part. The telescopic drive member 22 is connected to a mounting block 23, and the mounting block 23 has a sliding rod 24 that inserts into the guide groove 25. (Reference) Figure 2 and Figure 3 As shown, the movable part of the telescopic drive member 22 moves linearly, while the support rod 21 rotates. Therefore, the guide groove 25 on the support rod 21 slides with the sliding rod 24 to prevent the telescopic drive member 22 from locking with the support rod 21. The mounting block 23 serves as the connection medium between the telescopic drive member 22 and the sliding rod 24.

[0046] Specifically, the control component 70 includes grooves 71 respectively disposed on both lateral sides of the base 10, rolling elements 72 disposed in the grooves 71, and pressure sensors 73. The grooves 71 extend laterally at an angle and have a higher end and a lower end. The pressure sensor 73 is disposed at the higher end. In a laterally balanced state, the rolling element 72 is located at the lower end. In a laterally tilted state, the rolling element 72 on the side of the base 10 with a relatively lower height rolls to the higher end to trigger the pressure sensor 73. The grooves 71 include a higher end and a lower end, in which the rolling element 72 (e.g., a ball) is accommodated. The pressure sensor is disposed at the higher end. When the base 10 tilts, especially with a large tilt, the rolling element 72 will roll to the higher end and collide with the pressure sensor 73. The pressure sensor 73 can send an electronic signal to the controller to indicate that the base 10 is in a laterally tilted state. The controller can then control the support mechanism 20 to support the base 10 so that the base 10 returns to a laterally balanced state. Specifically, for the slide groove 71, the higher end of the slide groove 71 on the left side is located to the left of the lower end, and the higher end of the slide groove 71 on the right side is located to the right of the lower end. When the base 10 tilts to the left, the pressure sensor 73 in the slide groove 71 on the left side is triggered; of course, it can also be set up in the opposite way, so that if the base 10 tilts to the left, the pressure sensor 73 in the slide groove 71 on the right side is triggered.

[0047] The lower end is provided with a fourth elastic element 75 and a sliding plate 74, with the fourth elastic element 75 located between the sliding plate 74 and the base 10. When the base 10 is in a lateral equilibrium state, the rolling element 72 remains in contact with the sliding plate 74. When the base 10 experiences a slight vibration, the rolling element 72 will also vibrate accordingly. The fourth elastic element 75 can absorb the vibration energy, preventing the rolling element 72 from vibrating too violently and reaching the higher end.

[0048] The groove 71 is formed in an arc shape. (Reference) Figure 6As shown, the groove 71 extends from the horizontal direction to the vertical direction in an arc-shaped trajectory, forming a smooth turn. This means that when the base 10 is tilted at a large angle, the rolling element 72 will roll from the horizontal direction to move upward in the vertical direction, while at a smaller tilt angle, the rolling element 72 will not reach the higher end.

[0049] Additionally, the secondary equipment reliability monitoring device includes a mounting mechanism 40 and a second transmission assembly 60. The mounting mechanism 40 includes a mounting plate 41 connected to the base 10, a mounting seat 42 disposed on the mounting plate 41, a sliding column 43 slidably disposed on the mounting seat 42 in a vertical direction, and a protective cover 44 connected to the sliding column 43. The monitoring element 50 is disposed on the mounting seat 42. The rotation of the upper end of the support rod 21 can drive the sliding column 43 to move downward through the transmission assembly, thereby causing the protective cover 44 to cover the monitoring element 50. The mounting plate 41 is located on the upper side of the base 10 and can be connected to the base 10 through a connecting column. The mounting seat 42 is disposed on the mounting plate 41, and the monitoring element 50 can be disposed on the mounting seat 42. The mounting base 42 forms a vertical hole to accommodate the sliding column 43. When the upper end of the support rod 21 rotates inward (its lower end rotates outward), the sliding column 43 can be pushed downward by the second transmission assembly 60, thereby protecting the monitoring element 50 through the protective cover, that is, covering the monitoring element 50 when lateral tilting occurs.

[0050] Specifically, the second transmission assembly 60 includes a second rack 63 extending laterally corresponding to each of the two support rods 21, a push plate 66 connected to the second rack 63, a second take-up roller 61 rotatably mounted on the mounting plate 41, a second gear 64 coaxially connected to the second take-up roller 61, a second connecting rope 62 with its two ends connected to the second take-up roller 61 and the sliding column 43 respectively, and a second elastic member 65 disposed between the mounting base 42 and the sliding column 43. The support rods 21 can push the push plate 66 toward the second gear 64, so that the rack pushes the second gear 64 and the second take-up roller 61 to rotate, thereby retracting the second connecting rope 62 to drive the sliding column 43 and the protective cover 44 to descend. (Reference) Figure 4 and Figure 5 As shown, the second transmission assembly 60 includes two second racks 63 and two push plates 66. The support rod 21 can push the second racks 63 inward through the push plates 66, thereby driving the second gear 64 and the second take-up roller 61 to rotate, so as to retract the second connecting rope 62, thereby pulling the sliding column 43 downward. The central axis of the second take-up roller 61 extends longitudinally. The two second racks 63, the two push plates 66, the second take-up roller 61, and the second gear 64 can be arranged in the mounting cavity 45 of the mounting plate 41.

[0051] Additionally, the second transmission assembly 60 includes a third elastic member 67 disposed between the push plate 66 and the mounting plate 41. For example... Figure 4 As shown, a third elastic element 67 is provided in the mounting plate 41, which can apply an outward force to the push plate 66, for example, applying a leftward elastic force to the push plate 66 on the left side.

[0052] The telescopic drive component 22 is a hydraulic cylinder. The telescopic drive component 22 can also be other forms, such as an electric cylinder or a pneumatic cylinder. The hydraulic cylinder includes a cylinder body and a piston rod, which drives the support rod 21 to rotate.

[0053] refer to Figure 1 and Figure 4 The secondary equipment reliability monitoring device includes two monitoring elements 50 symmetrically arranged in the lateral direction. The monitoring elements 50 are oriented towards both sides, that is, outwards respectively.

[0054] The base 10 includes a moving mechanism 11. The moving mechanism 11 can drive the base 10 to move on the ground or a supporting surface, and the moving mechanism 11 may include tracks.

[0055] The second elastic element 65, the third elastic element 67, and the fourth elastic element 75 can be springs or elastic rubber, etc.

[0056] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the inventive concept, various simple modifications can be made to the technical solutions of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
