The housing 1 has an inner cavity 11 and a transition cavity 12 that are connected to each other. The end of the transition cavity 12 away from the inner cavity 11 is provided with an opening 120 that is connected to the outside of the housing 1. The ultraviolet sensor 2 is connected to the housing 1 and is located in the inner cavity 11. The ultraviolet collecting end 21 of the ultraviolet sensor 2 is arranged toward the opening 120.

The bird-repelling component 5 includes a bird-repelling rod 50 and a driving motor 51. The driving motor 51 is connected to the shell 1 and is located in the inner cavity 11.

The bird-repelling rod 50 is spaced apart from the ultraviolet sensor 2 and one end of the bird-repelling rod 50 points to the opening 120. The driving motor 51 can at least drive the bird-repelling rod 50 to move in the direction from the inner cavity 11 to the transition cavity 12.

[0045] By making the high-voltage electrical testing device 100 include a bird-repelling component 5, and the driving motor 51 of the bird-repelling component 5 is electrically connected to the control module, so that the driving motor 51 can be controlled to start through the control module, so that the driving motor 51 can at least drive the bird-repelling rod 50 to move from the inner cavity 11 to the transition cavity 12, so that the end of the bird-repelling rod 50 pointing to the opening 120 can move toward the opening 120, so that wild birds that may stay in the transition cavity 12 can be automatically expelled through the bird-repelling rod 50.

[0046] In addition, by making the shell 1 have a connected inner cavity 11 and a transition cavity 12, the transition cavity 12 has an opening 120 for ultraviolet rays to enter, and the ultraviolet sensor 2 is arranged in the inner cavity 11, the ambient light can be shielded to a certain extent by the side wall of the transition cavity 12, so as to increase the proportion of ultraviolet rays radiated by the high-voltage circuit aimed at by the opening 120 in the ultraviolet rays collected by the ultraviolet sensor 2, thereby reducing the influence of ambient light on the detection result of the ultraviolet sensor 2 and improving the electrical testing accuracy of the high-voltage electrical testing device 100.

[0047] Furthermore, by providing a power supply 4, the high-voltage electrical testing device 100 can have the function of storing electricity, so that when the high-voltage electrical testing device 100 is difficult to obtain power supply due to an uncontrollable outdoor environment, the power supply 4 can be used to maintain the normal operation of the high-voltage electrical testing device 100, so as to better realize the function of long-term and continuous monitoring of the status of the high-voltage circuit in the high-voltage power transmission system.

[0048] Optionally, the shell 1 located at the periphery of the transition chamber 12 can be formed into a trumpet-shaped structure in which the outer diameter of the shell 1 decreases from the opening 120 to the inner chamber 11, so that the cross-sectional area where the transition chamber 12 connects to the inner chamber 11 is smaller, which can further reduce the possibility of debris entering the inner chamber 11 through the transition chamber 12. At the same time, the diameter of the opening 120 can be made larger, thereby.

[0049] Optionally, the ultraviolet sensor 2 can be fixedly connected to the housing 1 via a connecting structure, so that the relative position of the ultraviolet sensor 2 and the opening 120 can be easily kept stable, thereby making it easier for the ultraviolet sensor 2 to maintain a stable ultraviolet collection effect on the area where the opening 120 is aligned.

[0050] Please combine Figure 3 As shown, optionally, the bird-repelling component 5 includes a plurality of bird-repelling rods 50, and the plurality of bird-repelling rods 50 are arranged at intervals around the ultraviolet sensor 2, so that the bird-repelling component 5 includes a larger number of bird-repelling rods 50 to increase the effective area of ​​the bird-repelling effect of the bird-repelling component 5, thereby improving the bird-repelling effect.

[0051] Furthermore, the bird-repelling assembly 5 also includes a slide cylinder 52 and a slide rod 53.

By making multiple bird-repelling rods 50 all fixedly connected to the slide cylinder 52, the relative postures between the bird-repelling rods 50 can be made more stable, so that the bird-repelling action area of ​​the bird-repelling assembly 5 is more stable. By fixing the slide rod 53 to the side of the ultraviolet sensor 2 away from the opening 120, and making the slide cylinder 52 slidably sleeved on the slide rod 53, the movement trajectory of the bird-repelling rod 50 relative to the ultraviolet sensor 2 can be limited by the slide cylinder 52 and the slide rod 53, thereby making the bird-repelling effect of the bird-repelling rod 50 in the area near the ultraviolet sensor 2 more stable.

[0052] Optionally, the driving motor 51 is any motor that can output rotational motion, and the bird-repelling assembly 5 also includes a gear 54 and a rack 55. The gear 54 is arranged at the driving end of the driving motor 51, and the rack 55 is meshingly connected to the gear 54, and the rack 55 is extended along the relative directions of the inner cavity 11 and the transition cavity 12. The bird-repelling rod 50 is fixedly connected to the rack 55, so that the rotational motion output by the driving motor 51 can be converted into linear motion through the gear 54 and the rack 55, so that the bird-repelling rod 50 can be driven by the driving motor 51 to move in the direction from the inner cavity 11 to the transition cavity 12.

[0053] In other embodiments, the driving motor 51 may also be a cylinder, a linear motor, etc. that can output linear motion, so that the driving motor 51 can drive the bird-repelling rod 50 to move in the direction from the inner cavity 11 to the transition cavity 12.

[0054] In order to reset the bird-repelling rod 50 after moving in the direction from the inner cavity 11 to the transition cavity 12 , in an optional embodiment, the driving motor 51 may output a reverse rotational motion or a linear motion to drive the bird-repelling rod 50 to reset.

[0055] like Figure 4 and Figure 5 As shown, in another optional embodiment, the bird-repelling assembly 5 may further include an elastic member 56, which is connected between the rack 55 and the shell 1. The elastic member 56 can apply elastic force to the rack 55, so that the rack 55 has a tendency to move away from the opening 120, so that the drive motor 51 that does not have a self-locking function after power failure can be used. After the drive motor 51 is powered off, the rack 55 can be pushed in a direction away from the opening 120 by the elastic member 56 to drive the bird-repelling rod 50 to reset.

[0056] Optionally, the bird-repelling assembly 5 also includes a limiting slider 57 and a limiting cylinder 58, the limiting cylinder 58 is fixed to the shell 1, the limiting slider 57 is fixed to one end of the rack 55, the limiting slider 57 can be slidably matched with the inner wall of the limiting cylinder 58 along the relative direction of the inner cavity 11 and the transition cavity 12, and an elastic member 56 is connected between the limiting slider 57 and the shell 1 in the limiting cylinder 58, so that the limiting slider 57 can cooperate with the limiting cylinder 58 to limit the relative movement trajectory of the rack 55 relative to the shell 1, thereby facilitating the rack 55 to remain in a connected state meshing with the gear 54 on the one hand, and further improving the stability of the movement trajectory of the bird-repelling rod 50 on the other hand, so as to further improve the stability of the bird-repelling effect of the bird-repelling rod 50.

[0057] Optionally, the high-voltage electrical testing device 100 further includes a dust removal component 6, which includes a rotating shaft 60, a first fan blade 61, and a second fan blade 62.

When the electrical testing device 100 is used outdoors, natural wind force can be used to drive the first fan blade 61 to rotate, so as to drive the rotating shaft 60 and the second fan blade 62 to rotate through the first fan blade 61, so that the second fan blade 62 can stir the air in the inner cavity 11 to form an airflow flowing from the inner cavity 11 to the transition cavity 12 to the opening 120, thereby being able to blow impurities in the transition cavity 12 out of the interior of the shell 1, and at the same time preventing impurities outside the shell 1 from entering the transition cavity 12, so as to further reduce the impact of impurities on the ultraviolet sensor 2.

[0058] Optionally, the power source 4 may be electrically connected to an external power supply circuit, or the high-voltage electrical testing device 100 may have the function of supplying power to the power source 4 .

[0059] When the high-voltage electrical testing device 100 has the function of supplying power to the power source 4, optionally, the dust removal component 6 also includes a generator 63, the generator 63 is located in the inner cavity 11 on the side of the second blade 62 facing the first blade 61, the generator 63 includes a rotor 631 and a stator 632, the rotor 631 is fixed to the rotating shaft 60, and the stator 632 is fixed to the housing 1 and is spaced at the outer periphery of the rotor 631, one of the rotor 631 and the stator 632 includes a winding, and the other includes a magnet, and the winding is electrically connected to the power source 4, so that the natural wind force can be used to drive the first blade 61 to rotate, so as to drive the rotor 631 to rotate relative to the stator 632, so as to generate current in the winding, so as to charge the power source 4. This arrangement can improve the cleanliness of the energy used by the high-voltage electrical testing device 100, and there is no need to additionally wire the high-voltage electrical testing device 100 to be electrically connected to an external circuit, which can reduce the difficulty of installing the high-voltage electrical testing device 100.

[0060] It can be understood that the generator 63 is any existing generator 63 including a stator 632 and a rotor 631, wherein when the rotor 631 includes a winding and the stator 632 includes a magnet, the generator 63 is a DC generator 63, and when the rotor 631 includes a magnet and the stator 632 includes a winding, the generator 63 is an AC generator 63.

[0061] When the bird-repellent assembly 5 also includes a slide bar 53 as described in the aforementioned technical solution, the end of the rotating shaft 60 located in the inner cavity 11 can be rotatably connected to the end of the slide bar 53 away from the ultraviolet sensor 2, so that the slide bar 53 and the rotating shaft 60 can support each other, so that the relative postures of the slide bar 53 and the rotating shaft 60 with the shell 1 are more stable.

[0062] Optionally, the high-voltage electrical testing device 100 also includes a support rod 3, one end of the support rod 3 is connected to the shell 1, and one end of the rotating shaft 60 located in the inner cavity 11 can be rotatably connected to the support rod 3, so that the support rod 3 can support one end of the rotating shaft 60 located in the inner cavity 11, so that the relative posture of the rotating shaft 60 and the shell 1 is more stable.

[0063] When the bird-repelling assembly 5 further includes a slide bar 53 as described in the aforementioned technical solution, the end of the slide bar 53 away from the ultraviolet sensor 2 can also be fixedly connected to the support bar 3, so that the relative posture between the slide bar 53 and the housing 1 can be more stable.

[0064] Optionally, the power supply 4 is located on the side of the second blade 62 facing the first blade 61, so as to avoid interference between the power supply 4 and the second blade 62, the bird-repelling assembly 5 and the ultraviolet sensor 2. When the dust removal assembly 6 also includes a generator 63 as described in the above technical solution, such an arrangement can also make the distance between the power supply 4 and the winding closer.

[0065] The present invention also provides a control method for a high voltage electrical testing device, please refer to Figure 2 and Figure 3 The control method is used to control the high voltage electrical testing device 100 as described in the above technical solution. Specifically, the control method includes:

[0066] When the control module detects that the power storage capacity in the power supply 4 is greater than a predetermined threshold, the control module controls the drive motor 51 to work; when the control module detects that the power storage capacity in the power supply 4 is less than or equal to the predetermined threshold, the control module controls the drive motor 51 to cut off power.

[0067] Therefore, when the amount of stored electricity in the power supply 4 is greater than a predetermined threshold, the control module can be used to control the drive motor 51 to operate, so that the high-voltage electrical testing device 100 can automatically drive away birds. When the amount of stored electricity in the power supply 4 is less than or equal to the predetermined threshold, the control module can be used to cut off the power supply to the drive motor 51, so that the high-voltage electrical testing device 100 can suspend the automatic bird driving operation to give priority to the power supply to the ultraviolet sensor 2, thereby ensuring the stability of the high-voltage electrical testing device 100's monitoring function of the state of the high-voltage circuit in the high-voltage power transmission system.

[0068] It can be understood that the predetermined threshold can be selected according to actual usage and design requirements. For example, the predetermined threshold can be selected as 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45% or 40% of the maximum storage capacity of the power supply 4.

[0069] In addition, the control method of the control module to control the operation of the drive motor 51 can be adapted to the specific working conditions of the drive motor 51 .

[0070] For example, as described in the above-mentioned technical solution, when the drive motor 51 drives the bird-repelling rod 50 to drive away birds and reset by alternately outputting forward and reverse rotational motion or linear motion, when the power storage amount in the power supply 4 is greater than a predetermined threshold, the control module can control the drive motor 51 to alternately output forward and reverse rotational motion or linear motion.

[0071] When, as described in the aforementioned technical solution, the bird-repellent assembly 5 also includes an elastic member 56, so that the bird-repellent rod 50 can be reset through the elastic member 56 after the drive motor 51 is powered off, when the stored electricity in the power supply 4 is greater than a predetermined threshold, the control module can control the power supply 4 to intermittently supply power to the drive motor 51, so that the drive motor 51 intermittently outputs rotational motion or linear motion, and when the drive motor 51 is powered off, the bird-repellent rod 50 can be reset through the elastic member 56.
