Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction of clay tennis courts, in particular to a leveling device for the construction of clay tennis courts. Background Technique
[0002] A clay tennis court refers to a ground made of natural clay or processed clay. More precisely, it is a "soft court", which is a porous and water-permeable tennis court. The most typical representative of clay courts is the French Open. Clay courts belong to sand courts, and it is the most typical representative of sand courts. In addition, various common green earth and muddy ground can be called sand courts. The elasticity of clay courts is higher than that of hard courts and grass courts, and it can bounce the ball above the player's shoulders, so it also slows down the rhythm of the game. Therefore, some people call clay courts slow courts, while hard courts can only bounce the ball to the height of the waist or even the knees, and the game rhythm is fast, so they are called fast courts. For players who are good at hitting looping balls, playing on clay courts is more advantageous. In addition, standing a little further back is also the secret to winning on clay courts. On the contrary, in fast court games, players like to play net shots more, which is more advantageous for players with quick reactions and rapid movements.
[0003] When building a clay tennis court, in order to keep the levelness of the court consistent, a leveling device is usually needed for measurement. Leveling means making an object on the same horizontal plane. In building construction, it means that bricklayers build walls and carpenters plane wood to make the uneven surfaces flat. Leveling is generally used in building construction. As the name implies, it uses some equipment, such as a level, a theodolite and other instruments, to make the surface and side of the masonry or construction object look flat without slope. Leveling is a ground construction process. Leveling: Taking the horizontal control line on the wall column and the leveling pier as the signs, check the flatness, shovel off the high parts, fill the concave parts, scrape flat with a horizontal scraping bar, and then rub flat the surface with a wooden trowel. For those with slope requirements, the slope should be made according to the design requirements.
[0004] For the current measurement method, a straightedge is usually placed on the road surface, and then workers observe the gap height between the straightedge and the road surface. Multiple measurements are required during measurement, which is extremely time-consuming and laborious, and the efficiency is extremely low.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-4 , in the present invention, a leveling device for the construction of a red clay tennis court includes a base 1. The bottom surface of the base 1 is fixedly connected with a support wheel 2. The bottom surface of the base 1 is fixedly connected with a shrinkage cylinder 3. The inner wall of the shrinkage cylinder 3 is fixedly connected with an inductor 4. A spring 5 is fixedly connected inside the shrinkage cylinder 3. Two limit grooves 6 are opened inside the shrinkage cylinder 3. A cross plate 7 is slidably connected in common inside the two limit grooves 6. The upper surface of the cross plate 7 is fixedly connected with the bottom end of the spring 5. The bottom surface of the cross plate 7 is fixedly connected with a detection wheel 8. One end of the detection wheel 8 away from the cross plate 7 penetrates through the shrinkage cylinder 3 and extends below the shrinkage cylinder 3.

[0025] The working principle of the present utility model is as follows:
[0026] When the detection wheel 8 comes into contact with the ground, the spring 5 will be stressed, and while driving the detection wheel 8 to expand and contract, it will contact the ground. When pushing the device to move, if the ground is uneven, the spring 5 will drive the cross plate 7 and the detection wheel 8 to expand and contract through its elasticity. The sensor 4 continuously detects whether there is a distance change in the cross plate 7. When there is a distance change in the cross plate 7, it will convey information to the warning sound 10. After receiving the signal, the warning sound 10 will play a warning sound to the staff, thereby completing the detection of whether the ground flatness is consistent.
