Description

The maintenance work covers aspects such as daily cleaning, regular in-depth maintenance, damage repair, and environmental control.

[0003] The ground of a gymnasium is generally made of rubber and wood. During use, due to frequent extrusion, stretching, or friction, stress concentration will occur inside the floor. When it exceeds its limit, cracking will occur.

The rolling cylinder 904 is disassembled and replaced with a water - absorbing roller 905, so that the water - absorbing roller 905 is detachably connected to the rotating connecting frame 902. Thus, the clear water in the water tank can be sprayed out from the adjustable nozzle 7, the clear water is sprayed onto the ground, and then the ground is rolled and cleaned by the water - absorbing roller 905, so that the ground can be cleaned.

[0038] The ground maintenance method includes the following steps: S1 At the maintenance station, the sports ground maintenance device is adapted to the ground cleaning work by replacing the module accessories. Specifically, the heating device 3 is replaced with a water tank 11, and the rolling cylinder 904 is disassembled and replaced with a water - absorbing roller 905. S2 The maintenance device performs the ground cleaning work under the control of the host computer. The moving platform 1 is controlled by the controller to move, and at the same time, the water in the water tank 11 is sprayed out through the adjustable nozzle 7 to clean the ground. S3 During the ground cleaning process of the maintenance device, the control module 8 collects information about the ground. S4 The infrared sensor 801 collects temperature images, and the vision sensor 802 collects ground images. S6 The host computer generates and receives the temperature images and ground images. Due to the effect of ground heat transfer, when there are cracking and gluing phenomena, gaps appear between the floor and the ground, resulting in the cracking and gluing parts being lower than the normal temperature, and cold spots will appear in the temperature images. It is detected whether there are cold spots in the temperature images. If there are cold spots, a repair path is generated according to the distribution position of the cold spots in combination with the ground images. Specifically, a repair route is constructed based on the position between the maintenance station and the distribution position of the cold spots. S7 The maintenance device returns to the maintenance station to replace the module accessories to make it suitable for the ground repair work. S8 The maintenance device repairs the ground according to the repair path.

[0039] Repair principle: First, the controller controls the heating liner 302 to heat the internal solid materials. The melted hot-melt materials flow into the bottom discharge device 2 through the discharge hole 303. At the same time, the bottom discharge device 2 sends the hot-melt materials into the repair spray head, and the materials are sprayed to the part to be repaired through the repair spray head. Then, the repair head 9 rolls over the ground. After the hot-melt materials are sprayed onto the ground, the rolling cylinder 904 rolls over the materials. Then, the scraper 903 scrapes off the excess materials. After the hot-melt materials cool down, the floor is repaired and leveled.

[0040] Thus, cracks on the ground can be identified during daily cleaning and maintenance. At the same time, the temperature at the crack is lower than the surrounding temperature, so cold spots are combined. According to the distribution position of the cold spots and the visual image, a repair path is constructed, so as to realize timely repair of the ground, making it possible to maintain large-scale stadiums and avoid the situation that the ground damage is not discovered in time due to the large maintenance area, resulting in the expansion of ground cracks.
