[0028] Please refer to Figures 1-3 , the present invention provides a technical solution: a rotary reverse flushing type grille movable auxiliary grille reset device, including the main body 1 of the dirt removal machine;
[0029] A protective device is provided on the main body 1 of the dirt removal machine;
[0030] The protective device includes a square tube 15, a fixing plate 12, a limiting plate 8 and a rubber block 13. The fixing plate 12 is fixedly connected inside one end of the sewage cleaner main body 1. The outer wall of the rubber block 13 is fixedly connected inside the groove formed on the upper outer wall of the fixing plate 12. The two ends of the square tube 15 are respectively rotatably connected to the corresponding inner walls on both sides of one end of the sewage cleaner main body 1 close to the fixing plate 12. Limiting plate grooves 9 are provided on the outer walls on both sides of one end of the sewage cleaner main body 1 close to the fixing plate 12. The outer walls on both sides of the limiting plate 8 are respectively slidably connected to the inside of the corresponding limiting plate grooves 9. Fixing bolts 10 are threadedly connected to the outer walls on both sides of one end of the sewage cleaner main body 1 close to the limiting plate 8. Fixing bolt grooves 14 are provided on the outer walls on both sides of the limiting plate 8. One end of each of the two fixing bolts 10 close to the fixing bolt grooves 14 threadedly extends into the inside of the fixing bolt grooves 14. An underwater movable auxiliary grid 3 is installed on the outer wall of the square tube 15. A first limiting groove 4 is provided on the outer wall of one end of the limiting plate 8 close to the sewage cleaner main body 1. A protective pad 11 is slidably connected to the inside of the first limiting groove 4. The upper outer wall of the underwater movable auxiliary grid 3 is in contact with the outer wall of the protective pad 11.
[0031] Among them, a main grid 2 is installed inside the upper end of the sewage cleaner main body 1. A pushing block groove 5 is provided on the upper outer wall of the limiting plate 8. A pushing block 6 is slidably connected to the inside of the pushing block groove 5. The pushing block 6 is in an "L" shape. Five reset springs 7 are arranged inside the pushing block groove 5. The two ends of the five reset springs 7 are respectively fixedly connected to the inner wall of the corresponding pushing block groove 5 and the outer wall of the pushing block 6. A limiting block groove 16 is provided on the outer wall of one end of the protective pad 11 close to the pushing block 6. One end of the lower part of the pushing block 6 close to the limiting block groove 16 slidably extends to the outer wall of the limiting plate 8 and is in contact with the inner wall of the limiting block groove 16.
[0032] Further, when using this device, it is started by connecting an external power supply. First, the square tube 15 adopts a solid structure to increase the overall gravity of the underwater movable secondary grid 3. The solid square tube 15 increases the torque at the hinge points of the solid part limiting plate 8 and the underwater movable secondary grid 3, improving the automatic reset ability of the underwater movable secondary grid 3. Then, the main body 1 of the sewage cleaner is started to operate the main grille 2. The side of the square tube 15 close to the main grille 2 is tilted by the generated force, driving the underwater movable secondary grid 3 to tilt. Then, there is a rubber block 13 at the contact between the fixing plate 12 and the square tube 15. Next, when the underwater movable secondary grid 3 abuts against the fixing plate 12, the rubber block 13 is deformed by the extrusion force of the underwater movable secondary grid 3 and the square tube 15. When the underwater movable secondary grid 3 automatically resets, the force generated by the deformation and recovery of the underwater movable secondary grid 3 can give a force to the underwater movable secondary grid 3 to assist in its reset. At the same time, when the underwater movable secondary grid 3 resets, the outer wall of the underwater movable secondary grid 3 contacts the outer wall of the protective pad 11, and the protective pad 11 absorbs the force generated by the reset of the underwater movable secondary grid 3, effectively protecting the underwater movable secondary grid 3. Then, when it is necessary to remove the protective pad 11, push the push block 6 in the opposite direction of the main grille 2 to drive the reset spring 7 to contract while the other end of the reset spring 7 disengages from the inside of the limit block groove 16. Then, pull the protective pad 11 to remove it from the limit plate 8. Next, turn the fixing bolt 10 to rotate so that the other end disengages from the inside of the fixing bolt groove 14. Then, pull the limit plate 8 to remove it from the main body 1 of the sewage cleaner.
[0033] When the underwater movable secondary grid 3 in the protection device automatically resets, the force generated by the deformation and recovery of the underwater movable secondary grid 3 can give a force to the underwater movable secondary grid 3 to assist in its reset. At the same time, when the underwater movable secondary grid 3 resets, the outer wall of the underwater movable secondary grid 3 contacts the outer wall of the protective pad 11, and the protective pad 11 absorbs the force generated by the reset of the underwater movable secondary grid 3, effectively protecting the underwater movable secondary grid 3. This avoids the collision of the underwater movable secondary grid 3 with the fixed structure during reset, effectively improving the service life of the underwater movable secondary grid 3. By pushing the push block 6 in the opposite direction of the main grille 2 to drive the reset spring 7 to contract while the other end of the reset spring 7 disengages from the inside of the limit block groove 16, and then pulling the protective pad 11, the protective pad 11 can be removed from the limit plate 8. This facilitates the removal of the protective pad 11, making it convenient for the staff to maintain and repair the protective pad 11, and at the same time improving the practicality and flexibility of the equipment.
[0034] Working principle: First, the square pipe 15 adopts a solid structure to increase the overall gravity of the underwater movable auxiliary grid 3. The solid square pipe 15 increases the torque at the hinge points of the solid part limiting plate 8 and the underwater movable auxiliary grid 3, improving the automatic reset ability of the underwater movable auxiliary grid 3. Then, start the main body 1 of the sewage cleaner to operate the main grille 2. The generated force causes the side of the square pipe 15 close to the main grille 2 to tilt, driving the underwater movable auxiliary grid 3 to tilt. Then, there is a rubber block 13 at the contact between the fixed plate 12 and the square pipe 15. When the underwater movable auxiliary grid 3 contacts the fixed plate 12, the rubber block 13 deforms under the extrusion force of the underwater movable auxiliary grid 3 and the square pipe 15. When the underwater movable auxiliary grid 3 automatically resets, the force generated by the deformation and recovery of the underwater movable auxiliary grid 3 can give the underwater movable auxiliary grid 3 a force to assist in its reset. At the same time, when the underwater movable auxiliary grid 3 resets, the outer wall of the underwater movable auxiliary grid 3 contacts the outer wall of the protective pad 11. The force generated by the reset of the underwater movable auxiliary grid 3 is absorbed by the protective pad 11, effectively protecting the underwater movable auxiliary grid 3. Then, when it is necessary to remove the protective pad 11, push the push block 6 to move in the opposite direction of the main grille 2, driving the reset spring 7 to contract and at the same time making the other end disengage from the inside of the limit block groove 16. Then, pull the protective pad 11 to remove it from the limit plate 8. Then, turn the fixing bolt 10 to rotate so that the other end disengages from the inside of the fixing bolt groove 14. Then, pull the limit plate 8 to remove it from the main body 1 of the sewage cleaner.

However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
