When the device is in use, the device is used for construction site The lifting and lowering protection plate 33 is slidably connected to the inner wall of the protective plate 1, and the rotating rod 35 contacts the lifting and lowering protection plate 33. When the lifting and lowering protection plate 33 is raised to the top, the lifting and lowering protection plate 33 leaves the protective plate 1. At this time, the protective plate 1 releases the restriction on the rotating rod 35, and the rotating rod 35 pops out through the connecting rod 34. At the same time, the rotating rod 35 drives the connecting rod 36 and the protective net 37 to pop out, so that the protective net 37 can block the stones or waste materials falling from the construction site, preventing the pedestrians passing by from being hit by the stones falling from the construction site, protecting the safety of pedestrians, improving the safety of the device, and ensuring the normal operation of the construction site. The supporting device 4 includes a connecting rod 2 41, an outer rod 42, an inner rod 43, an inclined block 44, a protective round block 45, an elastic telescopic rod 46, and an arc-shaped protrusion 47.

When the threaded rod 32 drives the lifting protection plate 33 to rise, the lifting protection plate 33 drives the inclined block 44 to rise. When the lifting protection plate 33 rises to the top, the inclined block 44 pushes the outer rod 42 forward through the connecting rod 2 41 through the inclined surface of the surface. At this time, the protective plate 1 releases the outer rod 42 The elastic member pushes the inner rod 43 out of the inner wall of the outer rod 42, so that the inner rod 43 supports the device, improves the stability of the device, and prevents the device from being blown down by strong winds in windy and rainy weather, and hitting pedestrians and workers, causing injuries to personnel, thereby protecting the safety of pedestrians and ensuring the normal progress of construction. The surface of the outer rod 42 contacts the inner wall of the protective plate 1, and the inclined block 44 contacts the outer rod 42. A hole is opened on the surface of the outer rod 42, and the hole contacts the arc-shaped protrusion 47. An elastic member is arranged between the inner wall of the outer rod 42 and the top of the inner rod 43. When the elastic telescopic column pushes the inner rod 43 out, when the inner rod 43 moves to a limited position, the outer rod 42 releases the restriction on the elastic telescopic rod 46, and the elastic telescopic rod 46 drives the arc-shaped protrusion 47 to pass through the hole on the surface of the outer rod 42, so that the inner rod 43 is fixed in a fixed position, preventing the device from being pushed down, protecting the safety of pedestrians, enabling the construction site to work normally, and improving the stability of the device.

[0014] Working principle: When the device is in use, it isolates the construction site, keeps pedestrians away from the construction site, and protects the safety of pedestrians. The motor 31 starts to work, and the output end of the motor 31 drives the threaded rod 32 to rotate. The lifting protection plate 33 is slid upward on the inner wall of the protective plate 1 through the rotation of the threaded rod 32, so that the lifting protection plate 33 is raised, the protection area of ​​the device is increased, and its protection effect is improved. When the lifting protection plate 33 rises to the top, the lifting protection plate 33 leaves the protective plate 1. At this time, the protective plate 1 releases the restriction on the rotating rod 35, and the rotating rod 35 pops out through the connecting rod 34. At the same time, the rotating rod 35 drives the connecting rod 36 and the protective net 37 to pop out, so that the protective net 37 can block the stones or waste materials falling from the construction site, preventing passers-by from being hit by the stones falling from the construction site, protecting the safety of pedestrians, improving the safety of the device, and ensuring the normal operation of the construction site. When the threaded rod 32 drives the lifting protection plate 33 to rise, the lifting protection plate 33 drives the inclined block 44 to rise. When the lifting protection plate 33 rises to the top, the inclined block 44 pushes the outer rod 42 forward through the connecting rod 2 41 through the inclined surface of the surface. At this time, the protective plate 1 releases the restriction on the outer rod 42. At this time, the elastic member pushes the inner rod 43 out of the inner wall of the outer rod 42, so that the inner rod 43 supports the device, improves the stability of the device, and prevents the device from decreasing in stability due to the rise. In windy and rainy weather, it is blown down by strong winds and hits pedestrians and staff, causing injuries to personnel, thereby protecting the safety of pedestrians and ensuring the normal progress of construction. When the elastic telescopic column pushes the inner rod 43, when the inner rod 43 moves to the limited position, the outer rod 42 releases the restriction on the elastic telescopic rod 46, and the elastic telescopic rod 46 drives the arc-shaped protrusion 47 to pass through the hole on the surface of the outer rod 42, so that the inner rod 43 is fixed in a fixed position, preventing the device from being pushed down, protecting the safety of pedestrians, enabling the construction site to work normally, and improving the stability of the device.

The fixed plate 51 is fixedly connected to the front of the protective plate 1, the slide bar 52 is slidably connected to the inner wall of the fixed plate 51, the spring 53 is sleeved on the surface of the slide bar 52, the baffle 54 is fixedly connected to the top of the slide bar 52, the U-shaped rod 55 is fixedly connected to the bottom of the fixed plate 51, and the fixed shaft 56 is fixedly connected to the bottom of the slide bar 52. The cleaning device 5 also includes a telescopic plate 57, a fixed rod 58, a fixed block 59, a rotating rod 510, a rotating plate 511, and an arc block 512. The telescopic plate 57 is rotatably connected to the fixed shaft 56. On the right side, the fixing rod 58 is rotatably connected to the inner wall of the telescopic plate 57, the fixing block 59 is fixedly connected to the top of the telescopic plate 57, the rotating rod 510 is fixedly connected to the inner wall of the fixing block 59, the rotating plate 511 is rotatably connected to the surface of the rotating rod 510, and the arc block 512 is fixedly connected to the top of the rotating plate 511. When the device is working, during construction, the stones falling from the construction site will be blocked by the protective net 37, but after a long period of work, the stones will accumulate on the surface of the protective net 37. Over time, the accumulated stones will crush the protective net 37, causing harm to personnel, affecting the normal progress of construction, and making the device unable to be used normally. When the stones in the protective net 37 are gradually accumulated, the weight will increase, thereby the protective net The rotating rod 35 will be driven downward by gravity, and the rotating rod 35 will push the baffle plate 54 to move downward, and the baffle plate 54 will push the slide bar 52 to move downward, and at the same time, the spring 53 will be squeezed, and the rotating rod 35 will push the fixed shaft 56 downward, and the fixed shaft 56 will push downward and drive the telescopic plate 57 to rotate through the fixed rod 58, so that the right end of the telescopic plate 57 moves upward, and at the same time, the telescopic plate 57 drives the fixed block 59 to move upward, so that the fixed block 59 supports the protection net 37, so that the protection net 37 will not be damaged by the pushed stones, and the stones will not fall and cause injuries to personnel, thereby protecting the safety of pedestrians and improving the service life of the device. The two ends of the spring 53 are respectively connected to the fixed plate 51 and the baffle plate 54. The plate 54 is fixedly connected, and the rear part of the fixed rod 58 is fixedly connected to the front part of the U-shaped rod 55. When the fixed block 59 rises, the fixed block 59 drives the rotating plate 511 to rise. At this time, the arc block 512 moves downward because of the stones in the protection net 37. The arc block 512 pushes the rotating plate 511 downward through the rotating rod 510. At this time, the other end of the rotating plate 511 will move upward because of the rotating rod 510. The rotating plate 511 will push the protection net 37 upward, so that the stones in the protection net 37 will fall from the inside, thereby preventing the stones from crushing the protection net 37, thereby improving the service life of the device, maintaining the normal use of the device, preventing the stones from crushing the protection net 37 and falling to injure pedestrians, and improving the safety of the device.

[0016] Working principle: when the device is working, during construction, stones falling from the construction site will be blocked by the protection net 37, but after a long period of work, the stones will accumulate on the surface of the protection net 37. In the long run, the accumulated stones will crush the protection net 37, causing harm to personnel, affecting the normal progress of construction, and making the device unable to be used normally. When the stones in the protection net 37 gradually accumulate, the weight will increase, so that the protection net 37 will drive the rotating rod 35 to move downward through gravity. At this time, the rotating rod 35 will push the baffle 54 to move downward, and the baffle 54 will push the sliding rod 52 to move downward, and at the same time squeeze the spring 53, and the rotating rod 35 will push the fixed shaft 56 downward. The fixed shaft 56 pushes downward and drives the telescopic plate 57 to rotate through the fixed rod 58, so that the right end of the telescopic plate 57 moves upward, and at the same time, the telescopic plate 57 drives the fixed block 59 to move upward The fixed block 59 moves to support the protection net 37, so that the protection net 37 will not be damaged by the pushed stones, causing the stones to fall and cause harm to personnel, thereby protecting the safety of pedestrians and improving the service life of the device. When the fixed block 59 rises, the fixed block 59 drives the rotating plate 511 to rise. At this time, the arc block 512 moves downward due to the stones in the protection net 37. The arc block 512 pushes the rotating plate 511 downward through the rotating rod 510. At this time, the other end of the rotating plate 511 will move upward due to the rotating rod 510, and the rotating plate 511 will push the protection net 37 upward, so that the stones in the protection net 37 will fall from the inside, thereby preventing the stones from crushing the protection net 37, thereby improving the service life of the device, maintaining the normal use of the device, preventing the stones from crushing the protection net 37 and falling to injure pedestrians, and improving the safety of the device.
