[0022] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example: Please refer to Figures 1 to 5 The present embodiment provides a large-span anchor-spray support rock tunnel waterproofing and drainage system, including a waterproof support mechanism 1, wherein two symmetrically arranged drainage grooves 2 for drainage are arranged in the waterproof support mechanism 1. The waterproof support mechanism 1 also includes a cleaning mechanism, which is arranged in both drainage grooves 2.

[0024] In this embodiment, the cleaning mechanism includes a horizontally arranged support plate 3, which is arranged in the drainage trough 2. Grooves 4 arranged along the length direction of the drainage trough 2 are opened on both side walls of the drainage trough 2, and tooth plates 5 are arranged in the grooves 4 on both sides. A double-axis motor 6 is arranged on the top surface of the support plate 3, and gears 7 meshing with the tooth plates 5 are arranged on both side output ends of the double-axis motor 6. The double-axis motor 6 can be connected to the support plate 3 in a detachable connection manner commonly used in the prior art, such as a screw connection, so as to facilitate subsequent disassembly; a collection box 8 is arranged below the support plate 3, and the collection box 8 is slidably connected in the drainage trough 2. A shovel plate 9 is arranged on the rear side wall of the collection box 8, and the shovel plate 9 is connected to the collection box 8. The shovel plate 9 is inclined on the rear side wall of the collection box 8, and the horizontally higher end of the shovel plate 9 is fixedly connected to the collection box 8, and the horizontally lower end of the shovel plate 9 contacts the bottom wall of the drainage trough 2.

[0025] Through the above-mentioned arrangement, when it is necessary to clean the drainage trough 2, the user starts working by controlling the dual-axis motor 6. After the dual-axis motor 6 starts working, it can drive the gear 7 to rotate. After the gear 7 rotates, it can mesh with the tooth plate 5 to enable the dual-axis motor 6 to move along the groove 4. After the dual-axis motor 6 moves, it can drive the support plate 3, the collecting box 8 and the shovel plate 9 to perform corresponding movements in the drainage trough 2 in turn. At this time, the shovel plate 9 can shovel up impurities such as pebbles and soil in the drainage trough 2 by contacting the bottom wall of the drainage trough 2. As such impurities accumulate on the shovel plate 9, such impurities accumulated to a certain extent will enter the collecting box 8 for collection, thereby realizing automatic cleaning of the drainage trough 2, avoiding blockage of the drainage trough 2, and saving manpower.

[0026] In order to facilitate the impurities on the shovel plate 9 to enter the collection box 8 for collection, the collection box 8 is provided with a fixed plate 10 that is symmetrically arranged on both sides. One end of the fixed plates 10 on both sides is fixedly connected to the corresponding side box wall of the collection box 8, and the other end extends outward from the collection box 8 to the top of the shovel plate 9. A brush roller 11 is rotatably connected between the extended ends of the fixed plates 10 on both sides, and the bristles of the brush roller 11 can abut against the plate wall of the shovel plate 9. A driving motor 12 is arranged on one side of the fixed plate 10, and the electric spindle of the driving motor 12 passes through the corresponding side fixed plate 10 and is fixedly connected to the brush roller 11. Through the above-mentioned arrangement, when the driving motor 12 starts working, it can drive the brush roller 11 to rotate between the fixed plates 10 on both sides. After the brush roller 11 rotates, it can sweep the impurities accumulated on the shovel plate 9 into the collecting box 8 for collection. The arrangement of the brush roller 11 and the shovel plate 9 can enable the cleaning mechanism to clean the drain trough 2 quickly and completely, so that the drain trough 2 will not be blocked after being cleaned by the cleaning mechanism.

[0027] In order to enable the support plate 3 to smoothly follow the movement of the dual-axis motor 6 in the drainage groove 2, first slide grooves 13 are provided on both side walls of the drainage groove 2, and the layout direction of the first slide grooves 13 is arranged along the length direction of the drainage groove 2. Slide blocks 14 are provided on both left and right side walls of the support plate 3, and both side slide blocks 14 are slidably connected in the first slide grooves 13 on the corresponding sides. When the dual-axis motor 6 starts to work, the two side slide blocks 14 can follow the movement of the support plate 3 to slide in the first slide grooves 13 on both sides. At the same time, the two side slide blocks 14 can limit the support plate 3 by extending into the first slide groove 13, thereby limiting the dual-axis motor 6, so that it will not flip due to the meshing of the gear 7 and the tooth plate 5 during operation, and can only move along the drainage groove 2.

[0028] In order to facilitate the subsequent cleaning of the collection box 8, a sliding cavity 15 is provided inside the support plate 3. The sliding cavity 15 is set to pass through the left and right side walls of the support plate 3. The sliders 14 on both sides are slidably connected in the sliding cavity 15 and extend outward from the sliding cavity 15 to be slidably connected in the first slide groove 13 on the corresponding side. The side walls of the sliders 14 on both sides away from the first slide groove 13 are connected together by setting springs 16. At the same time, second slide grooves 17 are provided on the front and rear side walls of the support plate 3. The second slide grooves 17 on both sides are connected with the sliding cavity 15. Control blocks 18 are provided on the front and rear side walls of the sliders 14 on both sides. The control blocks 18 are slidably connected in the second slide groove 17 on the corresponding side and extend outward from the second slide groove 17. According to the above arrangement, by pressing the control block 18, the slider 14 on the corresponding side can be moved away from the first slide groove 13 on the corresponding side and retracted into the slide cavity 15. When the slider 14 is completely moved out of the first slide groove 13 on the corresponding side, the support plate 3 and the double-axis motor 6 can be removed, and the support plate 3 and the collection box 8 can be taken out of the drain trough 2 to clean the collection box 8. After the collection box 8 is cleaned, the slider 14 is also retracted into the slide cavity 15 by pressing the control block 18, and then the support plate 3 is placed in a suitable position and connected to the double-axis motor 6, and then the control block 18 is released. At this time, the sliders 14 on both sides will move away from the slide cavity 15 under the reset action of the spring 16, so as to be able to re-enter the first slide groove 13 on the corresponding side.

[0029] In order to prevent large foreign matter from entering the drain trough 2, both drain troughs 2 are provided with a shielding net 19 that can cover the drain trough 2, and shielding covers 20 are provided on one end of each side of the shielding net 19, and both shielding covers 20 are connected to the drain trough 2 by bolts 21. Handles 22 are provided on the top surfaces of both shielding covers 20, and anti-slip stripes 23 are provided on both handles 22. The shielding net 19 can prevent large foreign matter from entering the drain trough 2, so as to avoid the situation that the cleaning mechanism cannot clean. The shielding cover 20 cooperates with the setting of the bolts 21 to install the shielding net 19 on the drain trough 2. The setting of the handles 22 and the anti-slip stripes 23 facilitates the user to take the shielding net 19 and the shielding cover 20.
