[0028] During the operation of the screen machine, foreign matter may adhere to the screen and need to be cleaned regularly. At present, the factory cleans the automatic screen machine manually, that is, the operator climbs onto the sewage regulating tank and manually flushes the screen. However, manual cleaning will lead to the risk of the operator being clamped by the machine and the risk of the operator falling during the operation, resulting in a high risk factor for the operator. At the same time, the manual cleaning operation is inefficient and consumes a lot of working time.

[0029] In order to solve the above problems, the utility model proposes an automatic grille 2 dirt remover, please combine Figure 1 and Figure 2 The automatic grille 2 dirt remover comprises a body 1, a grille 2 and a cleaning assembly 3. The body 1 comprises a base 11 and a frame 12. The frame 12 is used to be installed beside the water pool to be cleaned. The base 11 is installed on the frame 12 and is used to be placed in the water pool to be cleaned. The two ends of the base 11 along its extension direction are respectively a water inlet end 111 and a dirt collecting end 112. The water inlet end 111 is inserted under the water surface of the water pool to be cleaned, and the dirt collecting end 112 is exposed in the water pool to be cleaned. The base 11 is arranged to be inclined upward from the water inlet end 111 to the dirt collecting end 112. A collection box 13 is arranged at a position of the frame 12 corresponding to the dirt collecting end 112. The grille 2 is arranged on the side of the base 11 away from the collecting box 13, and the grille 2 includes a plurality of rake teeth 21 arranged in sequence along the extension direction of the base 11. The grille 2 can rotate along the extension direction of the base 11 when driven by the driving device; the cleaning component 3 includes a baffle 31, a water supply pipeline 32 and a plurality of nozzles 33. The baffle 31 is connected to the frame 12 and suspended on the side of the grille 2 away from the base 11. The water supply pipeline 32 is arranged on the side of the baffle 31 facing the grille 2. A plurality of nozzles 33 are arranged at intervals on the baffle 31 and are all connected to the water supply pipeline 32. The nozzles 33 are used to spray water onto the grille 2.

[0030] The technical solution of the utility model is to suspend a baffle 31 on the side of the grille 2 away from the base 11, and set a water supply pipeline 32 and a plurality of nozzles 33 on the baffle 31, so that water is sprayed on the rake teeth 21 on the grille 2 through the nozzles 33 to wash away the residual foreign matter on the rake teeth 21. The spraying area of ​​the plurality of nozzles 33 arranged at intervals is large, and there are no dead corners, so that the cleaning is more thorough. Through the above-mentioned arrangement, on the one hand, water can be sprayed automatically without manual cleaning, thereby improving the cleaning efficiency and avoiding the risk of personnel falling. On the other hand, the baffle 31 is also blocked in front of the rake teeth 21, so that the operator will not be clamped by the machine, thereby reducing the incidence of safety accidents and improving safety reliability.

[0031] In one embodiment, the two ends of the baffle 31 are a connecting end and an extending end, respectively, the connecting end is connected to the frame 12, the extending end extends along the extending direction of the base 11, and the baffle 31 is arranged parallel to the base. The baffle 31 is arranged parallel to the base, so that the baffle 31 and the grille 2 located on the base are also arranged parallel, ensuring that the baffle 31 can fully cover the grille 2, further reducing the possibility of the operator being caught by the grille 2, and improving safety.

[0032] In one embodiment, the baffle 31 is provided with nozzle rows arranged at intervals, and the multiple rows of nozzle rows are arranged at intervals along the extension direction of the baffle 31. Each nozzle row includes multiple nozzles 33. The multiple nozzles 33 in any nozzle row are arranged at intervals along the direction perpendicular to the extension direction of the baffle 31, and the nozzles 33 in any two adjacent rows of nozzle rows are staggered. Through the multiple rows of staggered nozzles 33, the spraying area of ​​the nozzles 33 is further increased, thereby increasing the cleaning area of ​​the grille 2 and making the cleaning more thorough.

[0033] Furthermore, the part of the grille 2 exposed to the water surface forms a spraying area, the baffle 31 completely blocks the spraying area, and the multiple nozzles 33 are arranged corresponding to the spraying area. The baffle 31 only blocks the part of the grille 2 exposed to the water surface, which can save costs and simplify the structure, and can also avoid corrosion and damage of the baffle 31 under the water surface, thereby extending the service life of the baffle 31.

[0034] Specifically, each nozzle 33 is a fan-shaped nozzle 33. The mist sprayed by the fan-shaped nozzle 33 is in a straight line shape, and the spray is uniform and has a strong impact force, which is most suitable for the cleaning industry. The straight-line mist of the fan-shaped nozzle 33 has the greatest impact force in the middle section and slightly weaker impact force at both ends. According to this feature of the fan-shaped nozzle 33, a reasonable overlapping arrangement between adjacent sprays of multiple nozzles 33 can obtain a uniform spray effect on the entire spray section, so that the impact force of the entire spray area can be uniform.

[0035] Optionally, the water pressure of the nozzle 33 is 0.4 MPa to 0.5 MPa, preferably 0.45 MPa. The water pressure within this range can save water and cost while ensuring the cleaning effect on the grille 2.

[0036] In one embodiment, the baffle 31 is a transparent baffle 31. Setting the baffle 31 as a transparent baffle 31 facilitates operators to observe the state of the grille 2 behind the baffle 31 and adjust the water pressure or other settings of the nozzle 33 in time according to the state of the grille 2.

[0037] In one embodiment, a water inlet valve is further provided at the water inlet of the water supply pipeline 32, and the water inlet valve is used to control the on-off of the water inlet. The on-off of the water inlet is controlled by the water inlet valve, thereby controlling the start and stop of the nozzle 33. When the cleaning demand is low, the nozzle 33 can be stopped from spraying water to reduce water consumption.

[0038] Furthermore, the water inlet valve is a solenoid valve, and the cleaning component 3 also includes a controller, which is electrically connected to the water inlet valve and is used to control the opening and closing of the water inlet valve. Compared with manual control, controlling the opening and closing of the water inlet through the solenoid valve and the controller is more convenient and safer, and further reduces the incidence of safety accidents.

[0039] Specifically, a first preset time and a second preset time are set in the controller, so that after every first preset time, the controller controls the water inlet valve to open and spray water, and the spraying continues for a second time, thereby further saving water.

[0040] In one embodiment, a collecting pipeline 14 is connected between the sewage collecting end 112 and the collecting box 13, and a collecting bucket 15 is provided at one end of the collecting pipeline 14 close to the sewage collecting end 112, with the large end of the collecting bucket 15 facing the sewage collecting end 112 and the small end facing the collecting pipeline 14. The collecting bucket 15 guides the garbage and foreign matter collected by the grille 2 into the collecting pipeline 14, and while guiding, the initial velocity of the garbage and foreign matter can be reduced, so as to avoid excessive impact force damaging the collecting pipeline 14, and the foreign matter can be evenly diverted.

[0041] Furthermore, a bending portion 16 is provided at one end of the collection pipe 14 near the collection box 13, and the bending portion 16 is arranged downwardly from the collection pipe 14 in a direction away from the pool to be cleaned. The arrangement of the bending portion 16 reduces the speed at which garbage and foreign matter enter the collection box 13, avoids excessive impact force to damage the collection box 13, and prolongs the service life of the collection box 13.

[0042] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
