Description

Technical Field

[0001] This utility model relates to the field of power transmission and transformation engineering, and more specifically, to a wiring calibration device for power transmission and transformation engineering. Background Technology

[0002] Wiring calibration devices for power transmission and transformation projects are crucial tools in power systems to ensure the accuracy and reliability of wiring. Primarily used on-site in power transmission and transformation projects, these devices precisely calibrate the wiring of power equipment and the layout and connection of cable lines. They can measure and output various signals to detect and correct errors in the wiring process in real time, thereby ensuring the stability and security of power signal transmission. The calibration device boasts advantages such as high precision, high stability, and portability, making it adaptable to the complex and ever-changing environmental requirements of industrial sites. In power transmission and transformation projects, the use of wiring calibration devices is of great significance for improving project quality, reducing fault occurrences, and ensuring the stable operation of the power system. It is not only an indispensable part of power construction but also a vital guarantee for ensuring the safe and efficient operation of the power system.

[0003] The wiring calibration instrument's side face is equipped with multiple interfaces, which are important channels for connecting the device to the outside world. However, these interfaces lack effective dust protection measures, such as dust covers or dust filters, allowing dust to directly contact and enter the interface without hindrance. This situation is particularly serious in dusty environments. Due to the lack of special dust protection at the interfaces, dust can easily penetrate the device through interface gaps under the influence of wind, airflow, or human factors. Once dust enters the device, it may adhere to critical components, affecting their normal operation and even causing faults such as short circuits and poor contacts. Therefore, for wiring calibration devices installed in power transmission and transformation projects in dusty environments, it is essential to strengthen dust protection measures at the interfaces to ensure the stable operation and reliability of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a power transmission and transformation engineering wiring calibration device to solve the problem that the interface of the power transmission and transformation engineering wiring calibration instrument lacks dustproof measures, which easily leads to dust entering the device and affecting the normal operation of the components. Therefore, it is necessary to strengthen the dustproof treatment and make it convenient to use.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model discloses a wiring calibration device for power transmission and transformation projects, including a main unit and a switch disposed on the upper surface of the main unit. Interfaces are evenly arranged on the side end face of the main unit, and a heat sink is installed on the outer side of the interface.

[0007] Preferably, the heat sink has an internal cavity, and a partition and a lifting plate are installed inside the cavity. The partition is located on one side of the lifting plate and has a vertical structure, while the lifting plate has a horizontal structure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Combination Figure 1 This utility model discloses a power transmission and transformation engineering wiring calibration device, including a main unit 1 and a switch 2 disposed on the upper surface of the main unit 1. Interfaces 6 are evenly arranged on the side end face of the main unit 1. A heat sink 3 is installed on the outer side of the interface 6. A rotating disk 4 is disposed in the center of the outer surface of the heat sink 3. A connecting rod 5 is installed on the upper end face of the heat sink 3. The connecting rod 5 is disposed on the upper surface of the main unit 1. Dust plugs 34 are evenly installed on the inner surface of the heat sink 3. The dust plugs 34 correspond one-to-one with the interfaces 6. A pull rope 35 is movably sleeved on the surface of the dust plugs 34.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Combination Figures 2-5The heat sink 3 has a cavity 31 inside. A partition 32 and a lifting plate 33 are installed inside the cavity 31. The partition 32 is located on one side of the lifting plate 33. The partition 32 is a vertical structure, and the lifting plate 33 is a horizontal structure. The two ends of the retraction rope 35 pass around the dust plug 34 and are connected to the partition 32. The retraction rope 35 is located at the upper end of the lifting plate 33. A collar 36 is sleeved on the surface of the retraction rope 35. The collar 36 is located at the upper end of the retraction rope 35 inside the cavity 31. The inner dimension of the collar 36 is larger than the outer dimension of the retraction rope 35.

[0027] A connecting rod 37 is installed on the lower surface of the collar 36. The bottom end of the connecting rod 37 is connected to the upper surface of the lifting plate 33. A rotating rod 41 is provided in the center of the rotating disk 4. An adjusting disk 42 is installed at one end of the rotating rod 41. A pressing protrusion 43 is installed on the side surface of the adjusting disk 42. The pressing protrusion 43 abuts against the upper surface of the lifting plate 33.

[0028] In this embodiment, when the calibrator is needed, the rotating disk 4 is rotated, the rotating rod 41 drives the adjusting disk 42 to rotate, the squeezing protrusion 43 flips and squeezes the lifting plate 33, the lifting plate 33 moves down, and the lowered lifting plate 33 pulls the collar 36 down through the connecting rod 37. The collar 36 applies a downward force to the pull rope 35, and the pull rope 35, which was originally in a straight state, becomes bent. Due to the contraction force of the pull rope 35, the dust plug 34 is compressed, deformed and becomes smaller. Then, when the heat sink 3 is flipped using the hinge of the connecting bar 5, the dust plug 34 is successfully detached from the inside of the interface 6.

[0029] When the calibrator is not needed, the heat sink 3 is flipped back to its original position, and the reduced-size dust plug 34 can smoothly enter the inside of the interface 6. The rotating disk 4 is rotated, and the two ends of the lifting plate 33 are limited to the inner wall of the cavity 31 and are equipped with springs. When the pressing protrusion 43 stops pressing the lifting plate 33, the lifting plate 33 quickly rises to its original height, the collar 36 returns to its original position, and the pull rope 35 is no longer subjected to downward force. Utilizing the elasticity of the dust plug 34, the dust plug 34 fills the inside of the interface 6 again, achieving the dustproof function. Thus, it will not affect normal use and can also prevent dust from entering the inside of the interface 6 and affecting the operation of the equipment.
