Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and in particular to a temperature monitoring structure for electrical equipment. Background Technology

[0002] Electrical equipment refers to the general term for various mechanical and electronic devices used in power systems for power generation, transmission, transformation, distribution, consumption, and power control and protection. It mainly includes core equipment such as generators, transformers, switchgear, circuit breakers, disconnectors, instrument transformers, surge arresters, cables, busbars, motors, distribution boxes, and control cabinets. These devices are responsible for the generation, transmission, transformation, distribution, and consumption of electrical energy. They are the infrastructure of modern industrial, civil, and commercial power systems, characterized by diverse voltage levels, wide power capacity ranges, complex operating environments, and stringent safety requirements. Their operating status directly affects the safety, stability, and power quality of the power system.

[0003] Traditional electrical equipment temperature monitoring devices are often fixed in place using mounting brackets, which are then bolted to the electrical equipment. However, in practice, the different pre-drilled bolt hole positions on the electrical equipment necessitate that the bolt connection method match the bolt hole positions and dimensions on both the mounting bracket and the electrical equipment to ensure compatibility. This installation method requires secondary drilling on the equipment to adjust the position of the mounting bracket when repositioning the temperature monitoring device, making the overall installation cumbersome. Furthermore, it requires that the specifications of the mounting bracket and the temperature monitoring device be identical; different specifications of temperature monitoring devices and mounting brackets cannot be directly interchanged, limiting the flexibility and adaptability of the installation.

[0004] Therefore, a temperature monitoring structure for electrical equipment is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a temperature monitoring structure for electrical equipment, which can quickly install and position the temperature monitoring meter to ensure its rapid installation on the electrical equipment, can quickly replace the temperature monitoring meter of different specifications to ensure the accuracy of monitoring, and can provide temperature measurement angles and positions in multiple locations.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An electrical equipment temperature monitoring structure includes a position adjustment component; The position adjustment assembly is equipped with a monitoring meter positioning fixture, and an electrical equipment temperature monitoring meter is detachably mounted on the monitoring meter positioning fixture. The position adjustment component includes a mounting bracket plate, two bearing seats are provided on the side of the mounting bracket plate, a threaded screw is rotatably arranged between the two bearing seats, and a screw nut is externally engaged with the threaded screw. A slider seat is sleeved on the outside of the lead screw nut, a rotary motor is mounted on the side of the slider seat, and a connecting plate is mounted on the outside of the output end of the rotary motor; The monitoring instrument positioning fixture includes a positioning plate disposed on the side of the connecting plate, and an adjustment seat is installed on the side of the positioning plate; The adjustment seat has a sliding groove on its front end face and two optical rods are installed inside it. Two clamping plates are sleeved on the outside of the two optical rods. Both clamping plates have clamping ring plates protruding from their opposite sides; The electrical equipment temperature monitoring meter is positioned between the two clamping ring plates.

[0007] Furthermore, both clamping ring plates are semi-circular and made entirely of rubber; the two clamping plates slide outside the optical rod and are symmetrically arranged.

[0008] Furthermore, a positive and negative threaded rod is rotatably arranged inside the adjusting seat, and the two clamping plates are respectively engaged with one of the threaded lines outside the positive and negative threaded rod.

[0009] Furthermore, both ends of the positive and negative threaded rods pass through the adjustment seat and are connected to adjustment handles.

[0010] Furthermore, a forward and reverse motor is mounted on the top of the mounting bracket plate.

[0011] Furthermore, the output end of the reversible motor passes through the mounting bracket plate and extends to connect with the top of the threaded screw. A bearing is installed at the connection between the mounting bracket plate and the reversible motor.

[0012] In summary, this utility model has the following beneficial effects: By coordinating multiple structures within the temperature monitoring fixture, rapid replacement and precise adaptation of temperature monitoring devices of different specifications are achieved. The synchronous counter-movement of the two clamping plates ensures uniform distribution of clamping force, allowing operators to quickly replace and reposition temperature monitoring devices in electrical equipment, reducing equipment downtime. The flexible clamping method of the semi-annular rubber clamping ring effectively avoids mechanical damage to the monitoring equipment while providing excellent vibration resistance, ensuring data stability during equipment operation.

[0013] The horizontal sliding function of the position adjustment component, combined with the automatic drive of the forward and reverse motor, enables multi-angle adjustment, allowing the electrical equipment temperature monitoring meter to be adjusted at multiple angles, covering the main monitoring areas of large electrical equipment such as transformers, switchgear, and busbars. The positioning fixture, through angle adjustment of the positioning plate and connecting plate, ensures that the electrical equipment temperature monitoring meter can accurately align with key heat-generating components such as cable joints, switch contacts, and insulators, thereby achieving precise temperature monitoring.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0018] First embodiment; Reference Figure 1-4 As shown, this is a preferred embodiment of the electrical equipment temperature monitoring structure, including a position adjustment component 1; The position adjustment assembly 1 is equipped with a monitoring meter positioning fixture 2, and the monitoring meter positioning fixture 2 is detachably equipped with an electrical equipment temperature monitoring meter 3; The position adjustment component 1 includes a mounting bracket plate 11. Two bearing seats 12 are provided on the side of the mounting bracket plate 11. A threaded screw 13 is rotatably provided between the two bearing seats 12. A screw nut 14 is externally engaged with the threaded screw 13. A slider seat 15 is sleeved on the outside of the lead screw nut 14. A rotary motor 16 is mounted on the side of the slider seat 15. A connecting plate 17 is mounted on the outside of the output end of the rotary motor 16. The monitoring positioning fixture 2 includes a positioning plate 21 disposed on the side of the connecting plate 17, and an adjustment seat 22 is installed on the side of the positioning plate 21; The adjusting seat 22 has a sliding groove 23 on its front end face and two light rods 24 are installed inside it. Two clamping plates 25 are sleeved on the outside of the two light rods 24. Two clamping plates 25 are each provided with a clamping ring plate 26 protruding from their opposite sides; The electrical equipment temperature monitoring meter 3 is positioned between two clamping ring plates 26.

[0019] In this embodiment, the rapid replacement and precise adaptation of temperature monitoring instruments of different specifications are achieved through the cooperation of multiple structures within the monitoring instrument positioning fixture 2. The synchronous counter-movement of the two clamping plates 25 ensures a uniform distribution of clamping force, allowing the operator to quickly replace and reposition the temperature monitoring instrument 3 of the electrical equipment, reducing equipment downtime. The flexible clamping method of the semi-annular rubber clamping ring plate 26 effectively avoids mechanical damage to the monitoring equipment while providing excellent vibration resistance, ensuring data stability during the operation of the electrical equipment.

[0020] In a preferred embodiment, the monitoring meter positioning fixture 2 of this application can adapt to various monitoring meter probes with diameters ranging from 10-50mm, including infrared thermometers, thermocouple sensors, and fiber optic thermometers. The sliding groove 23 in the adjusting seat 22 provides ample adjustment stroke, and with the double-ended operation of the adjusting handle 28, different specifications of monitoring meters can be replaced without damage within 5 minutes, avoiding the cumbersome process of disassembly and reassembly required by traditional fixing fixtures.

[0021] Furthermore, the horizontal sliding function of the position adjustment component 1, combined with the automatic drive of the forward and reverse motor 18, enables multi-angle adjustment, allowing the electrical equipment temperature monitoring meter 3 to be adjusted at multiple angles, covering the main monitoring areas of large electrical equipment such as transformers, switchgear, and busbars. The monitoring meter positioning fixture 2, through the angle adjustment of the positioning plate 21 and the connecting plate 17, ensures that the electrical equipment temperature monitoring meter 3 can be accurately aligned with key heat-generating parts such as cable joints, knife switch contacts, and insulators, thereby achieving precise temperature monitoring.

[0022] Second embodiment; Reference Figure 1-3As shown, both clamping ring plates 26 are semi-circular and made entirely of rubber; the two clamping plates 25 slide outside the light rod 24 and are symmetrically arranged.

[0023] In this embodiment, both clamping ring plates 26 are semi-circular and made entirely of rubber. This semi-circular structure cleverly forms a closable annular clamping space, ensuring that the electrical equipment temperature monitoring meter 3 is evenly wrapped and fixed during installation, avoiding the problem of scratching or deformation of the equipment shell that may be caused by rigid clamping. The choice of rubber material further enhances the cushioning and anti-slip performance of the clamping. The rubber has a moderate elastic modulus, which can provide sufficient friction when clamped, while absorbing vibration and impact, making it particularly suitable for electromagnetic interference or mechanical vibration environments during the operation of electrical equipment.

[0024] Third embodiment; Reference Figure 1-3 As shown, a positive and negative threaded rod 27 is rotatably installed inside the adjusting seat 22, and two clamping plates 25 are respectively engaged with one of the threaded lines outside the positive and negative threaded rod 27.

[0025] In this embodiment, a forward and reverse threaded rod 27 is rotatably mounted inside the adjusting seat 22. Two clamping plates 25 are respectively engaged with one of the threads on the outside of the forward and reverse threaded rod 27. When the forward and reverse threaded rod 27 rotates, one end of the thread rotates forward, pushing one clamping plate 25 inward, while the other end rotates in reverse, pushing the corresponding clamping plate 25 inward as well, forming a uniform clamping force. This ensures that the electrical equipment temperature monitoring gauge 3 is stably fixed between the two clamping ring plates 26, avoiding the asymmetrical stress that may result from unidirectional adjustment. The meshing connection of the threaded rod 27 provides high transmission efficiency and self-locking characteristics, reducing the impact of external vibration on the clamping position, making it suitable for dynamic monitoring scenarios in high-voltage electrical environments.

[0026] Fourth embodiment; Reference Figure 1-3 As shown, both ends of the positive and negative threaded rods 27 pass through the adjusting seat 22 and are connected to the adjusting handle 28.

[0027] In this embodiment, the operator can apply torque by holding the adjustment handle 28 from the side to rotate the lead screw 27 clockwise or counterclockwise, thereby synchronously driving the two clamping plates 25 to move inward or outward, and precisely controlling the tightness of the clamping ring plate 26 on the electrical equipment temperature monitoring meter 3.

[0028] Fifth embodiment; Reference Figure 4 As shown, a forward and reverse motor 18 is mounted on the top of the mounting bracket plate 11, and the mounting bracket plate 11 is provided with a number of positioning holes for matching bolt parts.

[0029] In this embodiment, the forward and reverse rotation function of the forward and reverse motor 18 allows the rotation of the lead screw 13 to achieve precise linear displacement of the slider seat 15 and the connecting plate 17 by driving the screw 13 through commands, thereby adjusting the position of the monitoring positioning fixture 2, which is suitable for electrical equipment inspection tasks that require frequent position switching.

[0030] Sixth embodiment; Reference Figure 4 As shown, the output end of the forward and reverse motor 18 passes through the mounting bracket plate 11 and extends to connect with the top of the threaded screw 13. A bearing is installed at the connection between the mounting bracket plate 11 and the forward and reverse motor 18.

[0031] In this embodiment, the output end of the forward and reverse motor 18 passes through the mounting bracket plate 11 and extends to connect with the top of the threaded screw 13. A bearing is installed at the connection between the mounting bracket plate 11 and the forward and reverse motor 18. This through-type connection ensures the directness and efficiency of power transmission. The bearing reduces friction loss, absorbs axial load, and maintains the smooth rotation of the screw 13, thus avoiding accuracy drift caused by the transmission of motor vibration to the bracket structure.

[0032] Specific implementation process: Step 1: By using bolts to align the positioning holes on the mounting bracket plate 11, the mounting bracket plate 11 is installed on the electrical equipment. Then, the operator starts the forward / reverse motor 18 on top of the mounting bracket plate 11. Its output end passes through the mounting bracket plate 11 and connects to the top of the threaded screw 13. The rotation direction of the threaded screw 13 is controlled by the forward / reverse rotation of the motor. The threaded screw 13 rotates between two bearing seats 12, driving the externally engaged screw nut 14 to move axially along the threaded screw 13. The slider seat 15 sleeved on the outside of the screw nut 14 then achieves precise linear displacement, thereby completing the coarse adjustment positioning of the monitoring gauge positioning fixture 2 in the vertical or horizontal direction. Step 2: After coarse positioning, the system enters the angle adjustment stage. The rotary motor 16 mounted on the side of the slider seat 15 starts working, and the connecting plate 17 mounted on the outside of its output end drives the entire monitoring instrument positioning fixture 2 to rotate, realizing the angle adjustment of the electrical equipment temperature monitoring instrument 3 in the horizontal plane. At the same time, in the adjusting seat 22 mounted on the side of the positioning plate 21 on the side of the connecting plate 17 in the monitoring instrument positioning fixture 2, the positive and negative threaded rods 27 start to rotate under the operation of the adjusting handles 28 at both ends. Since the positive and negative threaded rods 27 have two threads with opposite thread directions, the two clamping plates 25 respectively mesh with one of the threads. When the positive and negative threaded rods 27 rotate, the two clamping plates 25 will move closer or further away from the center at the same time, realizing the precise adjustment of the clamping distance. Step 3: The two clamping plates 25 slide symmetrically along the two smooth rods 24 within the sliding grooves 23 on the front end face of the adjusting seat 22. The clamping ring plates 26, which are protruding from opposite sides of the two clamping plates 25, gradually tighten. Since the clamping ring plates 26 are semi-circular and made entirely of rubber, they can gently and firmly clamp the cylindrical shell of the electrical equipment temperature monitoring meter 3, avoiding damage to the monitoring meter 3 while ensuring the reliability of the clamping. After the electrical equipment temperature monitoring meter 3 is securely set between the two clamping ring plates 26, the entire monitoring structure completes the entire workflow from coarse positioning and angle adjustment to precision clamping. At this point, the monitoring meter 3 is accurately located at the target temperature measurement point of the electrical equipment under test and can begin to perform temperature monitoring tasks.
