Technical Field

[0001] The utility model relates to the technical field of insulator detection, in particular to a handheld contact network insulator operating state detection device. Background Art

[0002] Catenary insulators are a vital component of the electrified railway system. Their main function is to support and insulate the contact wire to ensure the safety and stability of power transmission. With the rapid development of the railway transportation industry, especially the widespread promotion of high-speed railways and urban rail transit, the detection of the operating status of catenary insulators has become particularly important. Insulators may experience a decline in insulation performance due to environmental impact and material aging during long-term operation, which is directly related to the safe operation and maintenance costs of the line. Therefore, it is crucial to quickly and accurately detect the operating status of catenary insulators and promptly discover and handle potential faults to ensure the safe operation of electrified railways.

[0003] At present, the status detection of contact network insulators mostly relies on traditional electrical measurement methods, such as handheld detection equipment using fixed probes. Although these devices can provide certain detection functions, they have many limitations. For example, the spacing of the fixed probes cannot be adjusted, which limits the applicability of the equipment to insulators of different models and sizes, and reduces the flexibility and accuracy of detection.

[0022] The utility model provides a handheld contact network insulator operating state detection device.

[0023] In the embodiment of the present utility model, Figure 1As shown, the handheld contact network insulator operating status detection device includes a housing 1 and two probes 2, the housing 1 is formed with a straight extending sliding groove 121; each of the probes 2 includes a conductive part 21 and a detection part 22 that are relatively arranged, each of the conductive parts 21 can be slidably arranged in the sliding groove 121, and each of the detection parts 22 is arranged outside the housing 1, and the two detection parts 22 are respectively used to contact the steel needle and the steel cap of the insulator to be detected, and the two conductive parts 21 can slide in the sliding groove 121 to approach or move away from each other.

[0024] Specifically, the probe 2 is made of conductive material as a whole, and the conductive portion 21 can be connected to other components through wires (not shown) to detect the insulator voltage.

[0025] There are many ways of sliding connection of the conductive part 21, such as a slide rail can be set in the sliding groove 121, and the conductive part 21 can be matched with the slide rail, or the width of the sliding groove 121 can be made smaller than the diameter of the conductive part 21, and the groove wall of the sliding groove 121 is designed to be elastically deformable, and the conductive part 21 squeezes the groove wall of the sliding groove 121 to fix the conductive part 21. When the probe 2 is pushed hard, the conductive part 21 can squeeze the groove wall of the sliding groove 121 and slide along a preset direction.

[0026] It can be understood that the design of the present application allows the two probes 2 to move closer to or farther from each other along a predetermined path in the sliding groove 121, thereby adjusting the interval between the probes 2 so that the device can adapt to insulators of different sizes and shapes. This is particularly important for the detection of contact network insulators, because contact network insulators may have different design specifications due to their position and function in the railway system. In the present application, whether it is a smaller or larger insulator, the spacing between the probes 2 can be adjusted to ensure the best contact between the steel needle and the steel cap of the insulator, thereby effectively reducing data errors caused by poor contact.

[0027] Optionally, the housing 1 includes a hand-held end 11 and a detection end 12 opposite to each other, and the sliding groove 121 is formed at the detection end 12; wherein,

[0028] A marking portion 122 is formed on the surface of the detection end portion 12 , and the marking portion 122 is used to mark the interval between the two probes 2 .

[0029] Specifically, the hand-held end 11 can be used for mounting rods of different lengths so as to be held by a user. This part is a widely used technology and will not be described in detail here.

[0030] The surface of the detection end 12 is formed with a marking portion 122 , which can be realized by a mark, color difference or scale on a plastic or metal material, and is intended to provide visual or tactile feedback so that the user can clearly identify and adjust the interval between the probes 2 .

[0031] It is not difficult to understand that this design allows the operator to easily hold the device for operation, and at the same time, the relative position and spacing between the probes 2 are clearly displayed on the detection end 12 of the device, which increases the accuracy and convenience of the operation. Specifically, the sliding groove 121 is set at the detection end 12 and the identification part 122 that helps to identify the position of the probe 2 is set on the end. The operator can quickly identify and adjust the spacing between the probes 2 to ensure that each detection can achieve the best contact and measurement effect, which greatly improves the practicality of the device and the user-friendliness of the operation.

[0032] Optionally, the identification portion 122 is a scale formed on the detection end 12 , and a plurality of scale lines 122 a of the scale are arranged at intervals in the length direction of the sliding groove 121 , and each of the scale lines 122 a extends to the periphery of the notch of the sliding groove 121 .

[0033] The scale can be implemented by laser engraving or mechanical engraving on the surface of the detection end 12 to ensure the durability and accuracy of the scale.

[0034] It is not difficult to understand that by clearly marking the scale on the detection end 12 and extending the scale line 122a to the periphery of the notch, the accuracy of the user's adjustment of the position of the probe 2 is significantly improved. This scale setting not only makes the adjustment of the probe 2 spacing more intuitive and accurate, but also helps the operator to quickly adjust according to the actual situation of the on-site insulator, thereby ensuring the accuracy and reliability of the detection. In addition, the clear visibility of the scale line 122a is of great significance for maintaining the long-term use of the equipment and reducing operating errors, and improves the overall performance of the equipment and the convenience of operation.

[0035] Optionally, in the length direction of the sliding slot 121 , the colors of the multiple scale lines 122 a are set to be gradually changed.

[0036] This design means that the scale line 122a is extended along the sliding groove 121, and the color changes according to a certain rule (such as from light to dark or from one color to another).

[0037] The color-gradient scale lines 122 a may be realized in a variety of ways, such as by printing or coating with inks of different colors or by an electronic display panel (such as an LED or an LCD).

[0038] The color gradient scale line 122a design enhances visual recognition, especially in complex working environments or under low light conditions, and can effectively guide users to quickly identify and locate measurement points. In addition, the color gradient also has an intuitive educational effect, which can help new users quickly learn and master the use of the device, thereby improving the ease of use and educational value of the device.

[0039] Optionally, a limiting wall 13 is protruding from the bottom wall of the sliding groove 121, and the limiting wall 13 divides the sliding groove 121 into two sub-grooves 121a, one conductive part 21 is slidably disposed in one sub-groove 121a, and the other conductive part 21 is slidably disposed in the other sub-groove 121a.

[0040] The limiting wall 13 is usually made of a material that is the same as or compatible with the material of the housing 1. This structural setting is achieved through mechanical processing or mold injection molding, which ensures the structural firmness and long service life.

[0041] By setting the limiting wall 13, the conductive part 21 of each probe 2 moves in the independent sub-slot 121a, which not only improves the independence and operational flexibility of the probe 2, but also significantly enhances the safety. Specifically, by physically isolating the direct contact between the probes 2, electrical connection accidents caused by the contact between the probes 2 are effectively avoided. This isolation protection measure is particularly important for high-voltage or high-sensitivity detection environments, and can prevent accidental current conduction caused by improper operation or probe 2 failure, thereby ensuring the safety of operators and the normal operation of equipment.

[0042] Optionally, the conductive part 21 is spherical, and the conductive part 21 is rotatably disposed in the corresponding sub-slot 121a;

[0043] The groove side wall of each of the sub-grooves 121a includes an end wall 121b opposite to the limiting wall 13, and each of the end walls 121b is provided with an extension hole 121c. The conductive part 21 can rotate relative to the housing 1, and has a storage position where the corresponding probe 2 extends in the same direction as the corresponding sub-grooves 121a, and a detection position where the corresponding probe 2 extends from the notch of the sub-grooves 121a. In the storage position, the detection part 22 extends from the corresponding extension hole 121c.

[0044] The conductive part 21 is configured as a sphere and can be made of metal or other conductive materials to ensure good conductivity and durability. The shape of the sphere allows it to rotate freely inside the sub-slot 121a.

[0045] The spherical design and rotatable setting of the conductive part 21 provide extremely high flexibility and operational convenience. This design allows the conductive part 21 to adjust its position more flexibly when performing insulator detection, including rotation and sliding, to adapt to various detection angles and contact requirements. Such flexibility is particularly suitable for environments that require operations in complex or narrow spaces, such as on-site detection of contact network insulators. The spherical conductive part 21 can rotate within its track, so that the probe 2 can be easily adjusted from the detection position to the storage position, or vice versa, increasing the convenience and safety of the device. For example, when the probe 2 is not needed, it can be rotated to the storage position to prevent accidental damage or damage during carrying.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
