Description

Technical Field

[0001] This utility model relates to the field of lightning protection conduction technology, and in particular to an auxiliary tooling for testing the lightning protection conduction of UAV blades. Background Technology

[0002] In the field of lightning protection continuity testing for UAV blades, traditional testing methods have many drawbacks. For blade fixation, simple clamping or binding methods are often used, which not only make it difficult to ensure the stability of the blade during testing, but also easily cause the test position to shift due to shaking, affecting test accuracy. Furthermore, these methods have poor adaptability to different blade specifications and lack versatility.

[0003] During the adsorption and bonding process, the lack of an effective adsorption structure makes it difficult to achieve a tight and stable bond between the test component and the lightning arrester on the blade, affecting the continuity of current conduction and consequently the test results. Furthermore, during power connection and testing, the connection between the wires and the conductor is not secure enough and lacks necessary insulation protection measures, making leakage highly likely and posing a significant safety hazard to operators. Simultaneously, the metal components acting as conductors experience significant frictional wear over long-term use, leading to a decline in conductivity. This not only affects the stability of test results but also necessitates frequent replacements, increasing equipment maintenance costs. Utility Model Content

During the adsorption and bonding process, and during the power connection and testing process, the wire is connected to the metal rod through the threaded hole.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model provides an auxiliary tooling for testing the lightning protection conductivity of UAV blades, which includes as follows: Figure 1 As shown, it includes: a ground 1, a base 2 on the ground 1, a power supply 3 on the upper surface of the base 2, a wire 4 fixedly connected to the upper surface of the power supply 3, an insulating protective sleeve at the fixing structure of the wire 4, a metal rod 5 on the base 2, the outer surface of the metal rod 5 having a wear-resistant coating, the metal rod 5 penetrating the base 2, the lower surface of the metal rod 5 in close contact with the ground 1, a threaded hole 7 on the upper surface of the metal rod 5, the metal rod 5 being a conductor, the fixing structure of the wire 4 being a threaded hole 7 opened at the end of the metal rod 5, a blade 6 on the threaded hole 7, and a blade 6 having a design on the upper surface of the blade 6. A groove 13 is provided, and an adsorption connection component 11 is provided on the inner surface of the groove 13. An adhesion structure 10 is provided on the inner surface of the adsorption connection component 11. The adsorption connection component 11 is a strong magnet. The adsorption part of the adsorption connection component 11 has a device for adjusting the adsorption force. A conductive adhesive layer is provided between the adsorption part of the adsorption connection component 11 and the adhesion structure 10. The adhesion structure 10 is a flexible rubber layer provided on the surface of the strong magnet. A lightning arrester 12 is provided on the inner surface of the adhesion structure 10. A bolt 8 is threadedly connected through the inner surface of the blade 6. A nut 9 is threadedly connected to the outer surface of the bolt 8.

[0024] Specifically: Before testing, the blade 6 is placed in the threaded hole 7 at the top of the metal rod 5. A bolt 8 is passed through the blade 6 and threaded into the threaded hole 7. The bolt is then tightened with a nut 9 to secure the blade 6 firmly to the metal rod 5. The metal rod 5 acts as a conductor, with its lower surface in close contact with the ground 1, forming part of a grounding loop and providing a stable grounding environment for the test. Next, using the adsorption force of the adsorption connection assembly 11, the blade 6 is mounted on the blade 6 through the groove 13 on its upper surface, ensuring that the fitting structure 10 is in close contact with the lightning arrester 12. Since the adsorption part of the adsorption connection assembly 11 has an adjustable adsorption force device, the force can be adjusted according to the material of the lightning arrester 12. The adsorption force is adjusted according to the quality and surface condition to ensure a firm fit between the bonding structure 10 and the lightning arrester 12. At the same time, the conductive adhesive layer between the adsorption part and the bonding structure 10 can enhance the conductivity of both and ensure the smooth current conduction path. Then, the power supply 3 is connected to the threaded hole 7 at the end of the metal rod 5 through the wire 4 fixedly connected to its surface. The insulating protective sleeve at the fixing structure of the wire 4 can prevent leakage and ensure test safety. The wear-resistant coating on the outer surface of the metal rod 5 can reduce friction loss during use and ensure its stable conductivity. During the test, the current provided by the power supply 3 is transmitted to the metal rod 5 through the wire 4 in sequence. Since the metal rod 5 is a conductor and is in contact with the ground 1, it forms a ground.

[0025] Working Principle: Before testing, the blade 6 is placed in the threaded hole 7 at the top of the metal rod 5. A bolt 8 is passed through the blade 6 and threaded into the hole 7, then tightened with a nut 9 to secure the blade 6 firmly to the metal rod 5. The metal rod 5 acts as a conductor, with its lower surface in close contact with the ground 1, forming part of a grounding loop and providing a stable grounding environment for the test. Next, using the adsorption force of the adsorption connection assembly 11, the blade 6 is mounted on the blade 6 through the groove 13 on its upper surface, ensuring that the bonding structure 10 is in close contact with the lightning arrester 12. Since the adsorption part of the adsorption connection assembly 11 has an adjustable adsorption force device, the adsorption force can be adjusted according to the material and surface condition of the lightning arrester 12, ensuring a secure fit between the bonding structure 10 and the lightning arrester 12. Simultaneously, the conductive adhesive layer between the adsorption part and the bonding structure 10 enhances their adhesion. Conductivity ensures a smooth current conduction path. Then, power supply 3 connects to the threaded hole 7 at the end of metal rod 5 via a wire 4 fixedly connected to its surface. The insulating protective sleeve at the wire 4 fixing structure prevents leakage and ensures test safety. The wear-resistant coating on the outer surface of metal rod 5 reduces frictional loss during use, ensuring stable conductivity. During testing, the current supplied by power supply 3 is sequentially transmitted to metal rod 5 via wire 4. Since metal rod 5 is conductive and grounded by contact with ground 1, the current is conducted upwards along metal rod 5 to blade 6. Subsequently, the current is transmitted through the internal structure of blade 6 to lightning arrester 12, and then through bonding structure 10 and conductive adhesive layer to adsorption connection assembly 11, forming a complete current loop. By detecting the current conduction in this loop, it can be determined whether the lightning protection conductivity of the UAV blade meets the requirements.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
