After the cleaning pad 9 works for a long time, more impurities can be adhered to the surface of the cleaning pad, and meanwhile, some impurities can enter the cleaning pad 9 and are difficult to clean, so that the subsequent cleaning effect of the cleaning pad 9 can be affected, at the moment, by means of the structure, when the cleaning pad 9 is dirty, the sliding rod 8 moves downwards to the position of the push switch (not shown in the figure) and is extruded by the push switch through controlling the amplitude of the rotating end cover 5, so that the electric control valve 16 is opened, and after the water flow in the diversion hole 13 flows in from the connecting hole 15, the water flow can flow out from the cleaning pad 9 from inside to outside, so that the cleaning pad 9 can be washed from inside to outside, and the cleanliness and the subsequent using effect of the cleaning pad 9 are improved. When the total station 1 is used in cold days, frost exists on the surface of the lens 2 of the total station 1, the heating wire 19 in the cavity is started at the moment, so that the heating wire 19 heats water in the cavity, when the sliding rod 8 moves with the guide block 12, the guide block 12 and the stirring block 20 are made of magnetic materials, the stirring block 20 can be adsorbed when moving, the stirring block 20 moves towards the direction of the guide block 12, the stirring block 20 can stir the water in the cavity when moving, the water in the cavity can be uniformly heated, the situation that the water around the heating wire 19 is heated and the water at a distance is difficult to heat is avoided, after the hot water in the cavity is sprayed out, the effect of quickly melting the frost on the lens 2 is achieved, meanwhile, the effect of softening the cleaning pad 9 is achieved, the condition that the frost on the lens 2 and the frozen cleaning pad 9 scratch the lens 2 are avoided, and the effect of protecting the lens 2 is achieved.

When summer weather is hot, end cover 5 is when carrying out the rotation, can take the fixture block 27 of bottom rubber material to remove together for fixture block 27 passes fixed block 24 and with draw-in groove 26 block fixed, when end cover 5 gyration again resets, can be through flexible fixture block 27 and draw-in groove 26's cooperation, take fixed block 24 and slider 23 to remove together, the puggaree 25 moves together along with fixed block 24 this moment, and then play the effect of opening puggaree 25, let puggaree 25 be in the top of camera lens 2, and then reduce the condition that sunshine damaged to the spare part in the camera lens 2, when end cover 5 continued gyration reset, rubber material's fixture block 27 can warp the increase and then break away from draw-in groove 26. When weather is hot, the elastic membrane 6 is easy to damage during long-time insolation, the water guide cotton 28 is arranged to enable the water guide cotton 28 to absorb water in the cavity, the inverted L-shaped sliding block 23 moves along with the extrusion block 30 when moving, the short arm end of the sliding block 23 pushes the sliding plate 31 to move, the sliding plate 31 pushes against the protective sleeve 29 and the water guide cotton 28 at the corresponding positions, the situation that water flows upwards when the follow-up extrusion block 30 extrudes the water guide cotton 28 at the bottom is prevented, at the moment, the extrusion block 30 can extrude the water guide cotton 28 in the chute 33, and water stored in the water guide cotton 28 is extruded, and due to the blocking effect of the extrusion block 30, the water extruded in the water guide cotton 28 can only flow out from the port at the right side of the chute 33, so that the water flows onto the elastic membrane 6 and the end cover 5, and the functions of cooling and protecting the elastic membrane 6 and the lens 2 are further played. Through installation filter screen 35, filter screen 35 makes the water droplet that drips out can be finely divided (the water smoke of subdivision can evaporate heat dissipation fast), and then avoid the water droplet that drips out too big, lead to the water droplet to be comparatively concentrated, and be difficult to evenly contact or the slow condition of heat dissipation to elastic membrane 6 and camera lens 2, when simultaneously magnetic material's extrusion piece 30 slides to the direction of cotton 28 of guide, can repel with swinging rod 34 homopolar, swinging rod 34 rotates striking filter screen 35, and then will strike vibrations once more through the water of filter screen 35, reduce the residual of moisture, avoid the water droplet that drips out too big simultaneously, and get into its inside through the gap department of total station 1, and then lead to the circumstances of the damage of the short circuit of the inside electronic components of total station 1. Because the water-guiding cotton 28 is squeezed, rivers are mostly piled up in filter screen 35 bottom for rivers refine the effect not good when flowing out or being impacted, the water-guiding cotton that filter screen 35 surface set up this moment can be with the water absorption of bottom to make its evenly distributed in each position department of filter screen 35, when making follow-up swinging arms 34 striking filter screen 35, can make evenly distributed's rivers refine the effect better, thereby make water can even and finely divided distribution in elastic membrane 6 and camera lens 2 department, the cooling effect is better.
