DETAILED DESCRIPTION

[0028] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0029] Referring to Figures 1-8 .

[0030] The utility model discloses a monitoring device, including:

[0031] Camera body 1 is set up on the pole tower, and the camera body 1 is set up at the one side of cable 6 and line 7 junction, and the lens 11 direction of camera body 1 is aligned with line 7, is used for monitoring the ice and ice melting condition of line 7, and the end of camera body 1 close to lens 11 still has two oppositely arranged first chamber 12, and two first chambers 12 are arranged on the both sides of lens 11 respectively and communicate with the outside,

[0032] Protection component 2 includes convolution roller 21 arranged in each first chamber 12, and one convolution roller 21 is convoluted with protection film 22, and one end of protection film 22 extends from the corresponding first chamber 12 to the outside of camera body 1 and extends into another first chamber 12, and is convoluted on another convolution roller 21, and the side of protection film 22 close to camera body 1 contacts with lens 11, is used for blocking rain and snow and lens 11 contact, and the power unit 23 is further arranged in camera body 1, and the moving end of power unit 23 is connected with one of convolution roller 21, and further including the belt drive assembly 24 arranged in camera body 1, and one end of belt drive assembly 24 is connected with the moving end of power unit 23, and the other end is connected with the convolution roller 21 away from power unit 23, and power unit 23 is used to drive each convolution roller 21 to rotate,

[0033] Heating component 3 is arranged in each first chamber 12, and is used for heating protection film 22 convoluted on each convolution roller 21, and melting the ice and snow on protection film 22,

[0034] Cleaning component 4 is arranged at first chamber 12, and is used for cleaning protection film 22 to be entered into first chamber 12, and removing the floating snow on protection film 22 that has not frozen.

[0035] In the implementation, when the line 7 needs to be deiced, the input end of the cable 6 is connected with the deicing device, and the output end is connected with the line 7. The deicing device heats and deices the line 7 through the cable 6. At this time, the camera body 1 observes the deicing condition of the line 7, and the protective film 22 is attached to the lens 11, so as to prevent rain and snow from directly contacting the lens 11. At this time, the power unit 23 drives each convolution roller 21 to rotate through the belt transmission assembly 24, so as to move the protective film 22 from the corresponding convolution roller 21 to the other convolution roller 21. At this time, the protective film 22 moves relative to the lens 11, reducing the influence of the rain and snow attached to the protective film 22 on the lens 11. When the protective film 22 moves close to the other convolution roller 21, the cleaning component 4 scrapes the rain and snow remaining on the protective film 22, until the protective film 22 is convoluted on the corresponding convolution roller 21. At this time, the heating component 3 heats the protective film 22 on each convolution roller 21, so that the protective film 22 can be quickly dried. When the protective film 22 is wound from one convolution roller 21 to the other convolution roller 21, the power unit 23 drives each convolution roller 21 to rotate reversely, so that the protective film 22 can move reversely and be convoluted on the corresponding convolution roller 21, so that the protective film 22 can be reused.

[0036] In this way, through the cooperation between the protection component 2, the heating component 3 and the cleaning component 4, when the camera body 1 works, the protective film 22 is attached to the lens 11 and moves to the corresponding convolution roller 21, so as to prevent rain and snow from directly contacting the lens 11 and interfering with the work of the lens 11. Until the protective film 22 is convoluted on the corresponding convolution roller 21, the cleaning component 4 cleans the rain and snow remaining on the protective film 22. At this time, the heating component 3 heats the protective film 22 to accelerate the drying efficiency of the protective film 22. The power unit 23 drives the protective film 22 to be transported back and forth between the two convolution rollers 21, so that the protective film 22 can be used multiple times and protect the lens 11 for a long time, thereby ensuring the work of the camera.

[0037] It should be noted that the camera body 1 is also provided with a third chamber, and the power unit 23 and the belt transmission assembly 24 are arranged in the third chamber. The belt transmission assembly 24 includes two synchronous wheels 241 arranged on the moving end of the power unit 23 and the corresponding convolution roller 21 respectively, and a synchronous belt 242 connecting the two synchronous wheels 241. When the power unit 23 drives the corresponding convolution roller 21 to rotate, the synchronous wheel 241 arranged on the moving end of the power unit 23 drives the other synchronous wheel 241 arranged on the other convolution roller 21 to rotate through the synchronous belt 242, so as to realize the rotation of the two convolution rollers 21 driven by the power unit 23.

[0038] It should be noted that when the protective film 22 is moving, the two convolution rollers 21 can apply tension to the protective film 22 in the direction of the two convolution rollers 21, so that the protective film 22 can be effectively attached to the lens 11.

[0039] It should be noted that the temperature difference between the heating component 3 and the external air temperature is not too large, so that the protective film 22 does not fog when it is extended out of the camera body 1 and contacts the external cold air.

[0040] It should be noted that the camera body 1 and the tower can be provided with a mounting seat for positioning the camera body 1.

[0041] Preferably, the power unit 23 can adopt an existing motor.

[0042] In an embodiment, the cleaning component 4 includes two scrapers 41 rotatably arranged at one end of the camera body 1 close to the lens 11. The two scrapers 41 are oppositely arranged, and each scraper 41 is arranged on one side of a corresponding convolution roller 21. The scraping surface of each scraper 41 is in contact with the side of the protective film 22 away from the lens 11. The scraper 41 is used to remove the rain and snow attached to the protective film 22. Each scraper 41 is provided with a torsional spring (not shown in the figure) at the rotating connection with the camera body 1. The torsional spring provides a torsional force to the corresponding scraper 41 in the direction close to the lens 11.

[0043] In this way, when the corresponding convolution roller 21 drives the protective film 22 to extend out of the camera body 1, the torsional spring provides a torsional force to the corresponding scraper 41 in the direction close to the lens 11, so that the scraping surface of the scraper 41 is in contact with the side of the protective film 22 away from the lens 11. As the corresponding convolution roller 21 continues to rotate, the protective film 22 moves relative to the scraper 41. Before the protective film 22 is wound onto the corresponding convolution roller 21, the corresponding scraper 41 removes the rain and snow attached to the protective film 22, so that the protective film 22 does not carry the rain and snow to the corresponding convolution roller 21.

[0044] In an embodiment, the scraper 41 is composed of a scraping layer 411 and a wiping layer 412. The scraping layer 411 is arranged on the side of the wiping layer 412 away from the lens 11. The scraping layer 411 has an electric heating wire (not shown in the figure) passing therethrough. The electric heating wire heats the scraping layer 411. The wiping layer 412 is used to wipe the moisture on the protective film 22.

[0045] In this way, when the rain and snow is relatively large, the thickness of the rain and snow attached to the protective film 22 increases, at this time, the electric heating wire is powered on and heated for the corresponding scraping layer 411, before the protective film 22 is wound on the corresponding winding roller 21, the scraping layer 411 first contacts the rain and snow attached to the protective film 22, at this time, the scraping layer 411 scrapes and melts the rain and snow on the protective film 22, thereby speeding up the scraping efficiency, as the protective film 22 continues to move, the protective film 22 passes through the scraping layer 411 and contacts the wiping layer 412, at this time, the wiping layer 412 is used to wipe and absorb the excess moisture on the protective film 22, so that the protective film 22 can be wound on the corresponding winding roller 21 more dry, thereby improving the heating efficiency of the subsequent heating component 3 and improving the service life of the protective film 22.

[0046] It should be noted that the scraping layer 411 can be internally provided with a power supply for the electric heating wire, thereby ensuring the heating efficiency of the electric heating wire.

[0047] It should be noted that the wiping layer 412 can be made of cotton material or hemp material in the prior art, which has good water absorption and durability.

[0048] In an embodiment, the heating component 3 includes a heating sheet 31 arranged in each first chamber 12, each heating sheet 31 is arc-shaped and arranged on one side of the corresponding winding roller 21, and each heating sheet 31 is coaxially arranged with the corresponding winding roller 21, and the heating sheet 31 is used to heat the corresponding winding roller 21.

[0049] In this way, when the rain and snow on the protective film 22 is scraped by the corresponding scraper 41, the protective film 22 continues to move into the corresponding chamber and is wound on the corresponding winding roller 21, at this time, the heating plate heats the protective film 22 on the winding roller 21, thereby speeding up the drying speed of the protective film 22, and thereby enabling the protective film 22 to be used multiple times.

[0050] In an embodiment, the camera body 1 is also provided with two grooves 13 arranged on both sides of the moving direction of the protective film 22, and the grooves 13 are cross-distributed with the scraper 41;

[0051] The corresponding groove 13 of the camera body 1 is provided with a pressing component 5, the pressing component 5 includes a guide frame 51 arranged on one side of the groove 13, a pressing plate 52 is rotatably arranged on the guide frame 51, and a torsional spring is arranged at the rotating connection between the guide frame 51 and the corresponding pressing plate 52, the torsional spring applies a torsional force to the pressing plate 52 in the direction close to the protective film 22, the pressing plate 52 rotates in the direction close to the camera body 1, and the pressing plate 52 contacts and presses the corresponding side of the protective film 22 in the corresponding groove 13, thereby applying a pulling force to the protective film 22 in the direction close to the corresponding guide frame 51.

[0052] In this way, when the protective film 22 extends out of the camera body 1 and moves, the pressing plate 52 on each guide frame 51 rotates to the direction of the protective film 22 under the action of the torsion spring until the pressing plate 52 contacts the corresponding side of the protective film 22, and then the pressing plate 52 presses the corresponding side of the protective film 22 into the corresponding groove 13, thereby exerting a pulling force on the protective film 22 in the direction of the corresponding guide frame 51, and then the two convolution rollers 21 can exert a tension on both ends of the protective film 22, so that the protective film 22 can be rolled flat.

[0053] In an embodiment, the camera body 1 is also provided with a drainage groove 8, the water inlet of the drainage groove 8 is communicated with each first chamber 12, the water outlet of the drainage groove 8 is arranged at the bottom of the camera body 1 and communicated with the outside, and the drainage groove 8 is used for draining the water in each first chamber 12.

[0054] In this way, when each heating sheet 31 heats the protective film 22, the residual snow on the protective film 22 melts into water and drops into the corresponding first chamber 12, and then the water in each first chamber 12 flows into each drainage groove 8 and is drained out of the camera body 1, thereby avoiding the accumulation of water in each first chamber 12, and the water outlet of the drainage groove 8 arranged at the bottom of the camera body 1 can reduce the rain and snow entering the drainage groove 8 from the water outlet, thereby reducing the blockage.
