Description

[Technical Field]

[0001] The present invention relates to the technical field of power detection, and more particularly to a power line voltage detector. [Background technology]

[0002] Unmanned aerial vehicles (UAVs) can carry voltage detectors to approach power lines. These detectors are primarily used to detect whether a power line is charged. Information about the line's charge status is obtained by sensing the electric field around the line or by detecting ultraviolet light generated by corona discharge. This device avoids the risk of human contact with high-voltage power lines and allows for quick and flexible detection of power lines in various locations, greatly improving the efficiency and safety of power line voltage detection. Potential power line failure risks can be detected in a timely manner, ensuring the line's normal operation. The UAVs' use of ultraviolet detectors to detect power lines utilizes the principle that when a power line is charged, corona discharges can cause ultraviolet light to be emitted. During operation, the UAV approaches the line along a preset route. The ultraviolet detector captures the ultraviolet light, converts it into a signal, and transmits it to a control station on the ground. When dust adheres to the surface of a UV detector, it absorbs and scatters UV light. If dust adheres to the surface of a UV detector after it has been used for a long time, some of the UV light's energy is absorbed by the dust before it reaches the detector's photosensitive element, reducing the intensity of the UV light that can be detected.

Forms for implementing a utility model

[0017] In order to more clearly understand the technical problems, technical solutions, and beneficial effects solved by the present invention, we will now describe the present invention in detail and completely in combination with drawings and examples. The embodiments described herein are some of the embodiments of the present invention, but not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be combined in various different configurations.

[0018] Example 1 As shown in Figures 1-6, the first embodiment of the present invention is directed to a power line voltage detector. The unmanned aerial vehicle-based power line voltage detector includes a main assembly 100, a cleaning assembly 200, and a dust collection assembly 300. The three components work together to clean dust from the lens surface.

[0019] Specifically, the cleaning assembly 200 comprises a cleaning member 201, which has a moving member 201a, a hinge member 201b, a connecting member 201c, a fixed shaft 201d and a cleaning brush 201e. Two hinge members 201b are installed, each located at both ends of the connecting member 201c. The moving member 201a is hingedly connected to one end of the hinge member 201b. The hinge member 201b is fitted onto the fixed shaft 201d, and the cleaning brush 201e is fixed to one end of the fixed shaft 201d.

[0020] When the lens 102 needs to be cleaned, the moving member 201a rotates under the action of the rotating device, the rotation of the moving member 201a moves the hinge member 201b to rotate, the hinge member 201b moves the connecting member 201c to move, the movement of the connecting member 201c moves the fixed shaft 201d to move, the movement of the fixed shaft 201d moves the cleaning brush 201e to move, and the movement of the cleaning brush 201e can remove dust from the surface of the lens 102.

[0021] Specifically, the dust collection assembly 300 is arranged on one side of the cleaning brush 201e, and has a storage box 301a, a drawer 301b and a stop block 301c, the drawer 301b is slidably arranged on the inner wall of the storage box 301a, a stop groove 301b-1 is opened in the inner wall of the drawer 301b, and the stop block 301c is arranged on the inner wall of the storage box 301a.

[0022] By moving drawer 301b, drawer 301b moves retaining groove 301b-1, and retaining groove 301b-1 moves to one end of retaining block 301c, at which point retaining block 301c engages with retaining groove 301b-1. When cleaning brush 201e is used to wipe dust at one end of storage box 301a, the dust falls onto the inner wall of drawer 301b inside storage box 301a. If it is necessary to clean the dust inside drawer 301b after cleaning is completed, retaining block 301c is moved so that retaining block 301c escapes retaining groove 301b-1, and drawer 301b is pulled out one level, allowing the dust on the inner wall to be cleaned.

[0023] Example 2

[0024] 1-6, a second embodiment of the present invention is shown, which is based on the previous embodiment.

[0025] Specifically, a fixed rod 202a is inserted into the inner wall of the cleaning brush 201e, and a support plate 202b is attached to one end of the fixed rod 202a.

[0026] The fixed rod 202a is used to support the cleaning brush 201e, the cleaning brush 201e is movably connected to the fixed rod 202a, and the support plate 202b is used to support the fixed rod 202a.

[0027] Specifically, a connecting shaft 202c is inserted into the inner wall of the support plate 202b, a moving member 201a is fitted to the outside of one end of the connecting shaft 202c, and a worm wheel 202d is fitted to the outside of the other end of the connecting shaft 202c.

[0028] By turning the worm wheel 202d, the worm wheel 202d moves the connecting shaft 202c in rotation, which moves the moving member 201a in rotation.

[0029] Specifically, a worm rod 202e is installed at the bottom of the worm wheel 202d, and an impeller 202f is installed at one end of the worm rod 202e.

[0030] The other end of the worm rod 202e is rotatably mounted on the inner wall of the protective frame 202i, and transmits wind power to the impeller 202f by the rotation of the drone's propeller. At this time, the impeller 202f rotates under the action of the wind, and the rotation of the impeller 202f rotates the worm rod 202e, which in turn rotates the worm wheel 202d.

[0031] Specifically, a blower pipe 202g is installed on the top of the impeller 202f, and two fixing rings 202h are fitted on the outside of the blower pipe 202g.

[0032] The fixing ring 202h is used to support the air duct 202g, and the air duct 202g is used to send and guide the wind power generated by the drone's propeller. As the drone's propeller rotates, the wind power is contained within the air duct 202g and transmitted to the impeller 202f through the guidance of the air duct 202g.

[0033] Specifically, a protective frame 202i is fitted around the outside of the impeller 202f.

[0034] The protective frame 202i is used to protect the impeller 202f and also to collect wind power.

[0035] Example 3

[0036] 5-6, a second embodiment of the present invention is shown, which is based on the previous embodiment.

[0037] Specifically, a guide strip 302a is provided at one end of the container 301a, a supply groove 302a-1 is formed in the inner wall of the guide strip 302a, and a dustproof plate 302b is provided on one side of the supply groove 302a-1.

[0038] Dustproof plate 302b collects dust to prevent it from falling, causing it to fall into supply groove 302a-1, and then moves cleaning brush 201e to clean the dust on the surface of lens 102. When cleaning brush 201e finishes cleaning and moves to one side of storage box 301a, the dust cleaned by cleaning brush 201e falls onto guide strip 302a, then into supply groove 302a-1, and settles on the inner wall of drawer 301b.

[0039] Specifically, a fixing groove 301a-1 is drilled in the inner wall of the storage box 301a, and two support blocks 302c are installed at the bottom of each drawer 301b. A first spring 302d is fixed to one end of each support block 302c, and the other end of each first spring 302d is fixed to the inner wall of the fixing groove 301a-1.

[0040] When drawer 301b is placed in storage box 301a and dust needs to be collected, drawer 301b is pushed, causing drawer 301b to move support mass 302c against the inner wall of fixing groove 301a-1, which then moves and compresses first spring 302d. When drawer 301b moves along retaining groove 301b-1 and engages with retaining mass 301c, the installation of drawer 301b is complete, allowing dust to be collected. When dust on the inner wall of drawer 301b needs to be cleaned, retaining mass 301c is moved to separate from retaining groove 301b-1, at which point drawer 301b is ejected under the action of the repulsive force of first spring 302d.

[0041] Specifically, a support strip 302e is inserted into the inner wall of the stopper block 301c, and both ends of the support strip 302e are fixed to the inner wall of the storage box 301a. The stopper block 301c is movably connected to the support strip 302e. A second spring 302f is installed at the bottom of the stopper block 301c, and one end of the second spring 302f is fixed to the inner wall of the storage box 301a. A handle 302g is provided at one end of the stopper block 301c.

[0042] Support strip 302e is used to support stop mass 301c.

[0043] When dust on the inner wall of the drawer 301b needs to be cleaned, the handle 302g is moved, and the movement of the handle 302g moves the stopper mass 301c to separate it from the stopper groove 301b-1, and the movement of the stopper mass 301c compresses the second spring 302f. In addition, the movement of the drawer 301b applies pressure to the top of the stopper mass 301c, and at this time, the drawer 301b is ejected under the action of the repulsive force of the first spring 302d.

[0044] When the drawer 301b needs to be placed in the storage box 301a to collect dust, the drawer 301b is pushed, causing the drawer 301b to move the retaining groove 301b-1 to the edge of the retaining block 301c, at which time the retaining block 301c re-engages with the retaining groove 301b-1 under the action of the repulsive force of the second spring 302f.

[0045] Specifically, the power transmission line voltage detection device further comprises a main body assembly 100, which has an ultraviolet detector 101, a lens 102 and a mounting plate 103, the lens 102 is installed at one end of the ultraviolet detector 101, the mounting plate 103 is installed at the top of the ultraviolet detector 101, a support plate 202b is installed at the bottom of the lens 102, a fixing ring 202h is fixed to one end of the ultraviolet detector 101, a protective frame 202i is fixed to one end of the ultraviolet detector 101, and a guide strip 302a is fixed to one side of the lens 102.

[0046] The ultraviolet detector 101 is an instrument for detecting ultraviolet light. When the ultraviolet detector 101 is attached to the bottom of the drone, it can monitor the atmosphere at different altitudes. The lens 102 can adjust the ultraviolet light flux entering the detector. The mounting plate 103 is used to attach the ultraviolet detector 101 to the drone.

[0047] If lens 102 needs to be cleaned during use, drawer 301b is first placed on the inner wall of storage box 301a, and drawer 301b is then moved, causing support mass 302c to move toward the inner wall of fixing groove 301a-1, which then compresses first spring 302d. When drawer 301b moves fixing groove 301a-1 to one side of support mass 302c, support mass 302c re-engages with fixing groove 301a-1 under the action of second spring 302f, completing the installation of drawer 301b. Then, the drone is started, causing the drone's propeller to rotate. The rotation of the propeller causes air to enter the inner wall of air duct 202g, where it is sent to and guided by impeller 202f. At this time, the impeller 202f rotates under the action of wind, and the rotation of the impeller 202f rotates the worm rod 202e, which rotates the worm wheel 202d, which rotates the connecting shaft 202c, which rotates the moving member 201a, which rotates the hinge member 201b, which moves the connecting member 201c. The movement of the connecting shaft 202c moves the fixed shaft 201d, which moves the cleaning brush 201e, and the movement of the cleaning brush 201e can clean dust from the surface of the lens 102. When the cleaning brush 201e is moved to one end of the storage box 301a, the dust falls onto the guide strip 302a, which then falls into the supply groove 302a-1, and finally settles on the inner wall of the drawer 301b.

[0048] When dust on the inner wall of drawer 301b needs to be cleaned, handle 302g is moved. The movement of handle 302g moves locking mass 301c to separate it from locking groove 301b-1, and the movement of locking mass 301c compresses second spring 302f. In addition, the movement of drawer 301b applies pressure to the top of locking mass 301c. When locking mass 301c is moved to separate it from locking groove 301b-1, drawer 301b springs out under the action of the repulsive force of first spring 302d. This makes it possible to clean dust on the inner wall of drawer 301b, and then reattach drawer 301b to the inner wall of storage box 301a for next use.

Those skilled in the art can make various changes and modifications to the present invention. Any changes, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
