DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1 to 12 As shown, a sewer maintenance protective cover includes a central column 1, a left column 2 and a right column 3. Grooves 4 are provided on the left and right sides of the central column 1, the right side of the left column 2 and the left side of the right column 3. The front and rear sides of the inner wall of the groove 4 are fixedly connected with a first cylinder 5. The surface of the first cylinder 5 is fixedly connected with a first bearing 6. The surface of the first bearing 6 is fixedly connected with a connecting rod 7. The inner wall of the connecting rod 7 is fixedly connected with a second bearing 8. The inner wall of the second bearing 8 is fixedly connected with a second cylinder 9. The front and rear ends of the second cylinder 9 are fixedly connected with a first U-shaped plate 10. Threaded holes 11 are provided on the front and rear sides of the first U-shaped plate 10. The inner wall of the threaded hole 11 is threadedly connected with a locking bracket 12. A first locking groove 13 is provided on the side of the connecting rod 7. The inner wall of the first locking groove 13 fits with the surface of the locking bracket 12. A second locking groove 14 is provided at the bottom of the connecting rod 7.

[0033] Among them, the locking bracket 12 includes a threaded column 121, a rotating block 122 and a locking circular plate 123. The surface of the threaded column 121 is threadedly connected to the inner wall of the threaded hole 11. The front and rear ends of the threaded column 121 are fixedly connected to the surface of the rotating block 122. The surface of the threaded column 121 is fixedly connected to the inner wall of the locking circular plate 123. The surface of the locking circular plate 123 fits with the inner wall of the first locking groove 13.

[0034] It should be noted that the connecting rod 7 can rotate around the first cylinder 5 through the first bearing 6, and can rotate around the second cylinder 9 through the second bearing 8. When the user rotates the rotating block 122 on the locking bracket 12, the locking circular plate 123 can move forward or backward through the cooperation between the threaded column 121 and the threaded hole 11. When the locking circular plate 123 contacts the first locking groove 13, the connecting rod 7 cannot rotate through the cooperation between the locking circular plate 123 and the first locking groove 13, and the sewer maintenance protective cover is in an open state. When the locking circular plate 123 contacts the second locking groove 14, the connecting rod 7 cannot rotate through the cooperation between the locking circular plate 123 and the second locking groove 14, and the sewer maintenance protective cover is in a folded state.

[0035] like Figures 1 to 14As shown, the upper surface of the center column 1, the upper surface of the left column 2 and the upper surface of the right column 3 are all fixedly connected with the light-emitting component 15, and the interior of the center column 1, the interior of the left column 2 and the interior of the right column 3 are all provided with a sliding hole 16, and the inner wall of the sliding hole 16 is fitted with a pressing column 17, and the upper surface of the pressing column 17 is fixedly connected to the bottom of the light-emitting component 15.

[0036] Among them, the light-emitting component 15 includes a second U-shaped plate 151, an LED lamp 152, a battery box 153, a rechargeable battery 154 and a push switch 155. The upper surface of the central column 1, the upper surface of the left column 2 and the upper surface of the right column 3 are all fixedly connected to the bottom of the second U-shaped plate 151, the upper surface of the second U-shaped plate 151 is fixedly connected to the bottom of the LED lamp 152, the top of the inner wall of the second U-shaped plate 151 is fixedly connected to the upper surface of the battery box 153, and the rechargeable battery 154 is located inside the battery box 153. When the rechargeable battery 154 is low on power, the rechargeable battery 154 in the battery box 153 can be directly taken out of the battery box 153 and replaced. The bottom of the battery box 153 is fixedly connected to the upper surface of the push switch 155, and the bottom of the push switch 155 is fixedly connected to the upper surface of the push column 17. The push switch 155 is electrically connected to the battery box 153 and the LED lamp 152 respectively.

[0037] The upper surfaces of the central column 1 , the left column 2 and the right column 3 are all fixedly connected with internal thread rings 18 , and the inner walls of the internal thread rings 18 are threadedly connected with transparent protective covers 19 .

[0038] It should be noted that when the sewer maintenance protective cover is placed on the ground, the gravity of the sewer maintenance protective cover causes the pressing column 17 to press the pressing switch 155, and the LED light 152 is turned on by pressing the switch 155. At this time, the luminous LED light 152 allows the sewer maintenance protective cover to be clearly seen even in dim light at night. When the sewer maintenance protective cover is separated from the ground, the pressing column 17 no longer applies pressure to the pressing switch 155, and the LED light 152 is turned off by pressing the switch 155. At the same time, when the transparent protective cover 19 is screwed into the internal threaded ring 18, the light-emitting component 15 can be wrapped by the transparent protective cover 19, and the light-emitting component 15 will not be hit by hard objects.

[0039] The working principle of the present utility model is: first, by rotating the rotating block 122, the locking circular plate 123 is staggered with the connecting rod 7 under the cooperation of the threaded column 121 and the threaded hole 11, and then, by rotating the connecting rod 7, the connecting rod 7 on the first U-shaped plate 10 is in a horizontal state, and then, by rotating the rotating block 122, the locking circular plate 123 is in contact with the first locking groove 13 under the cooperation of the threaded column 121 and the threaded hole 11. At this time, through the cooperation of the first locking groove 13 and the locking circular plate 123, the connecting rod 7 cannot rotate, and the distance between the left column 2 and the center column 1, the distance between the right column 3 and the center column 1 and the distance between the adjacent center columns 1 reach the maximum value, and then, the sewer maintenance protective cover is covered at the sewer outlet, and the sewer maintenance protective cover is used to prevent pedestrians from falling into the sewer.

[0040] At the same time, when the sewer maintenance protective cover is idle, the rotating block 122 is first rotated to make the locking circular plate 123 staggered with the connecting rod 7 under the cooperation of the threaded column 121 and the threaded hole 11, and then, by rotating the connecting rod 7, the connecting rod 7 on the first U-shaped plate 10 is in a vertical state, and then, by rotating the rotating block 122, the locking circular plate 123 is in contact with the second locking groove 14 under the cooperation of the threaded column 121 and the threaded hole 11. At this time, through the cooperation of the second locking groove 14 and the locking circular plate 123, the connecting rod 7 cannot be rotated, and the center middle, left side column 2 and right side column 3 are folded together, so that the space occupied by the sewer maintenance protective cover when idle is smaller.

[0041] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
