[0039] One side of the sector 4 is provided with a first movable groove 41, and the other side of the sector 4 is provided with a second movable groove 42. The sector 4 is provided with a first fixed block 43 and a second fixed block 44 at an end away from the center. The sector 4 is movably provided with a first fixed cleaning brush 51, a first telescopic cleaning brush 52, a second fixed cleaning brush 53, and a second telescopic cleaning brush 54.

[0040] One end of the first fixed cleaning brush 51 is rotationally connected to the first fixed block 43. One end of the first telescopic cleaning brush 52 is telescopically arranged at the other end of the first fixed cleaning brush 51.

[0042] Specifically, the bottom surface (i.e., the light emitting surface) of the lamp body 3 is evenly divided into a plurality of sector-shaped areas 4 with the center of the bottom surface of the lamp body 3 as the center. The first fixed block 43 and the second fixed block 44 in each sector-shaped area 4 are oppositely arranged. When the other end of the first telescopic cleaning brush 52 moves along the first movable groove 41 and the other end of the second telescopic cleaning brush 54 moves along the second movable groove 42, the first fixed cleaning brush 51, the first telescopic cleaning brush 52, the second fixed cleaning brush 53, and the second telescopic cleaning brush 54 can clean the sector-shaped area 4, preventing dust from accumulating in the sector-shaped area 4 and affecting the light emission of the lamp body 3.

[0043] The sports venue lamp with good protection performance provided in the embodiment has a first fixed cleaning brush 51 provided with a first strip-shaped limiting groove 55. The first telescopic cleaning brush 52 is provided with a first limiting block 56 movably arranged in the first strip-shaped limiting groove 55. The second fixed cleaning brush 53 is provided with a second strip-shaped limiting groove 57. The second telescopic cleaning brush 54 is provided with a second limiting block 58 movably arranged in the second strip-shaped limiting groove 57.

[0044] Specifically, through the above arrangement, the first telescopic cleaning brush 52 can be prevented from falling off the first fixed cleaning brush 51, and the second telescopic cleaning brush 54 can be prevented from falling off the second fixed cleaning brush 53.

[0045] The first telescopic cleaning brush 52 is connected to the other end of the first driving column 61; the first driving column 61 penetrates through the first movable groove 41; the first driving column 61 is connected to the first counterweight 62; the first counterweight 62 is slidably arranged in the first movable groove 41; the other end of the second telescopic cleaning brush 54 is connected to the second driving column 63; the second driving column 63 penetrates through the second movable groove 42; the second driving column 63 is connected to the second counterweight 64; the second counterweight 64 is slidably arranged in the second movable groove 42; the top surface of the lamp body 3 is provided with a guide inclined surface 31 at the first movable groove 41 and the first movable groove 41; from the end far from the center to the end close to the center, the guide inclined surface 31 is arranged inclined downward; the first counterweight 62 and the second counterweight 64 are each provided with an abutting inclined surface matched with the guide inclined surface 31. The base 1 is rotatably provided with a guide rail seat 7; the guide rail seat 7 includes a central column 71 arranged at the middle, a containing groove 72 arranged outside the central column 71, and a vortex groove 73 arranged at the outer periphery of the containing groove 72; when the first counterweight 62 and the second counterweight 64 are arranged at the bottom of the guide inclined surface 31, the first driving column 61 and the second driving column 63 are contained in the containing groove 72. The containing groove 72 is movably provided with an arc-shaped stopper 74; a resisting spring 75 is arranged between the arc-shaped stopper 74 and the containing groove 72; the resisting spring 75 is used to drive the arc-shaped stopper 74 to abut against the central column 71. The base 1 is provided with a motor 81; the output end of the motor 81 is connected to the middle part of the guide rail seat 7. The motor 81 and the guide rail seat 7 are provided with a fan blade 82; the fan blade 82 is coaxially driven with the middle part of the guide rail seat 7.

[0046] Specifically, when the motor 81 stops working, under the gravity of the first counterweight 62 and the second counterweight 64, the first counterweight 62 and the second counterweight 64 move to the bottom of the guide inclined surface 31, i.e. the position close to the center, under the cooperation of the abutting inclined surface and the guide inclined surface 31; and under the action of the first spring 23, the top of the first driving column 61 and the top of the second driving column 63 are contained in the containing groove 72.

[0047] When the motor 81 works and rotates at a low speed, the centrifugal force generated by the arc-shaped stopper 74 is smaller than the elastic force of the resisting spring 75 due to the slow rotating speed of the guide rail seat 7, so that the arc-shaped stopper 74 is always in abutment with the center column 71, at this time, the arc-shaped stopper 74 cannot interfere with the first driving column 61 and the second driving column 63, that is, the accommodation groove 72, the first driving column 61 and the second driving column 63 are not in contact, so that the fan blade 82 rotates synchronously in the rotating process of the guide rail seat 7, thereby being capable of dissipating heat for the lamp body 3.

[0048] When the rotating speed of the motor 81 increases, the centrifugal force generated by the arc-shaped stopper 74 is greater than the elastic force of the resisting spring 75 due to the increase of the rotating speed of the guide rail seat 7, so that the arc-shaped stopper 74 moves away from the center column 71, thereby making the arc-shaped stopper 74 sequentially contact with the first driving column 61 and the second driving column 63, and push the first driving column 61 and the second driving column 63 to contact with the inner wall of the accommodation groove 72 respectively, and in the rotating process of the guide rail seat 7 and the arc-shaped stopper 74, the first driving column 61 and the second driving column 63 are pushed into the spiral groove 73, with the rotation of the guide rail seat 7, the first driving column 61 and the second driving column 63 are driven in the spiral groove 73, thereby moving away from the center along the first movable groove 41 and the second movable groove 42, thereby being capable of cleaning the bottom surface of the lamp body 3, preventing dust from accumulating in the fan-shaped area 4 to affect the light emission of the lamp body 3; and the fan blade 82 rotates synchronously, capable of blowing out the swept dust.

[0049] When the rotating speed of the motor 81 is the largest, the fan blade 82 generates a large air flow, under the pushing of the large air flow, the lampshade 2 moves downward, thereby separating the first driving column 61, the second driving column 63 and the guide rail seat 7, so that the first driving column 61 and the second driving column 63 reset under the action of gravity.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
