Description

Technical Field

[0001] The utility model relates to a detection auxiliary device, in particular to an auxiliary device for power distribution network fault detection, belonging to the technical field of detection auxiliary devices. Background Art

[0002] The distribution network refers to the power grid that receives electric energy from the transmission network or regional power plants and distributes it locally or step by step according to the voltage to various users through distribution facilities. It is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid. Common distribution network faults: ground faults, busbar faults, distribution line faults, etc. In the process of distribution network fault detection, relevant auxiliary tools are needed to improve work efficiency.

[0003] Existing fault detection tools used on site include ultraviolet imagers, which can help inspectors locate specific fault points through ultraviolet imaging. However, if the working environment on site is relatively harsh or the fault point is located in a position that is difficult for some personnel to reach easily, it is difficult for the portable ultraviolet imager to perform detection work. Therefore, in response to the above problems, an auxiliary device for distribution network fault detection is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an auxiliary device for distribution network fault detection. The detection auxiliary device can realize the movement of the ultraviolet imager by a drone, instead of the detection personnel carrying the ultraviolet imager, so that the ultraviolet imager can largely ignore the influence of adverse factors of the environment and space, improve the detection efficiency, and the protective tube and elastic support foot structure can protect the flight and landing of the drone, so that the auxiliary tool can be suitable for harsh working environments, solving the technical problem that the detection auxiliary tools in the prior art have strong limitations in space and environment when used.

[0005] In order to solve the above problems, the following technical solutions are provided:

[0006] An auxiliary device for distribution network fault detection is designed, including a UAV device, wherein the outer fixed covers of the rotor structure at the four corners of the UAV device are provided with protective cylinders, elastic supporting feet are fixedly arranged at the four corners of the bottom of the UAV device, a detection box is fixedly arranged at the center of the lower end surface of the UAV device, the detection box comprises a box shell, a longitudinal partition is arranged inside the box shell, an ultraviolet imager is fixedly installed in the space inside the box shell directly in front of the longitudinal partition, a transverse partition is fixedly arranged in the space inside the box shell behind the longitudinal partition, and a working circuit board is fixedly installed on the upper end surface of the transverse partition.

[0007] The above-mentioned structural form drives the movement of the ultraviolet imager through the drone equipment, so that the ultraviolet imager can easily cross the river and reach a high place, and send the imaging information back through the working circuit board. The inspection personnel only need to control the movement of the drone equipment to carry out the inspection of various power equipment in a large range, which can effectively improve the inspection efficiency and avoid casualties. The set protective tube can protect the rotor of the drone equipment, and the elastic support foot itself can change the inclination angle by deformation to ensure the stability of the drone equipment when landing on uneven ground, and can also play a buffering and protective role.

[0008] Furthermore, a battery compartment is formed by the box shell, the longitudinal partition and the transverse partition directly below the transverse partition, and a detachable battery module is arranged in the battery compartment.

[0009] The above structural form can realize convenient and rapid replacement of the detachable battery module, thereby ensuring that the device can be used continuously for a long time.

[0010] Furthermore, the protective tube includes a tube body and is fixedly connected to the UAV equipment, and a reinforcing strip is fixedly connected between the base end of the rotor structure of the UAV equipment and the inner wall of the protective tube.

[0011] The above-mentioned structural form enables the barrel body to be firmly fixed outside the rotor structure of the UAV equipment to protect it.

[0012] Furthermore, an upper mesh cover is fixed at the opening of the upper end of the protective tube, and a lower mesh cover is fixed at the opening of the lower end of the protective tube.

[0013] The above-mentioned structural form can prevent foreign objects in the environment from being drawn into the protective tube and causing damage to the rotor when the rotor of the UAV equipment drives the air flow.

[0014] Furthermore, the upper mesh cover and the lower mesh cover are both metal mesh covers and are connected to the protective tube by means of a slot connection.

[0015] The above structural form ensures that even if the upper net cover and the lower net cover are covered at both ends of the protective tube, the flow of airflow will not be affected, and the normal flight of the UAV equipment will not be affected.

[0016] Furthermore, the elastic supporting foot includes an upper bracket, the bottom end of the upper bracket is connected to a lower leg, the upper bracket and the lower leg are hinged by a hinge shaft, a hook ring is fixedly provided on the side of the top of the lower leg close to the upper bracket, the hook ring is connected to a spring, and the other end of the spring is fixed to the upper bracket by another hook ring.

[0017] The above-mentioned structural form can support the UAV equipment when it lands. In particular, when the landing surface is uneven, the four lower legs can pull the springs to increase the corresponding length according to the size of the force to achieve the balance of the force, so that the four lower legs can independently rotate at different angles to ensure that each lower leg can provide supporting force, ensuring the stability of the UAV equipment when it lands, and the springs can also play a buffering role when landing, removing the impact force during landing, and protecting the UAV equipment.

[0018] Furthermore, a bent and upwardly tilted contact foot is fixedly connected to the bottom end of the lower leg.

[0019] The above-mentioned structural form can prevent the lower supporting leg from being subjected to the force of landing and causing it to rotate so that the bottom end thereof extends outward and abuts against the ground, thereby hindering its rotation.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] In the utility model, the ultraviolet imager is driven to move by the drone equipment, so that the ultraviolet imager can easily cross the river and reach a high place, and send the imaging information back through the working circuit board. The inspection personnel only need to control the movement of the drone equipment to carry out the inspection of various power equipment in a large range. The protective tube can protect the rotor of the drone equipment, and the elastic support feet can improve the stability of the drone equipment when it lands on uneven ground, and can also play a buffering and protective role.
