[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0027] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the X-direction in the figure is the first direction, the Y-direction is the second direction, and the Z-direction is the third direction. The sewage interception device for water conservancy projects includes a support frame 1, a sewage interception component 2, and a sewage cleaning component 3. The sewage interception component 2 includes a first driving component 21 and a plurality of grating bars 22. The first driving component 21 is arranged on the support frame 1, and the plurality of grating bars 22 are arranged at intervals along the first direction at the output end of the first driving component 21. The first driving component 21 is used to drive the plurality of grating bars 22 to move along the first direction. The sewage cleaning component 3 includes a second driving component 31 and a sewage cleaning member 32. The second driving component 31 is arranged on the support frame 1, and the sewage cleaning member 32 is arranged at the output end of the second driving component 31, and the sewage cleaning member 32 is located on one side of the plurality of grating bars 22. The second driving component 31 is used to drive the sewage cleaning member 32 to clean the sundries on the plurality of grating bars 22.

[0028] The support frame 1 has an installation space for installing a plurality of grating bars 22. Specifically, the support frame 1 includes a bottom frame, side frames, and a top frame. The top frame is arranged above the bottom frame. There are two side frames, and the two side frames are respectively arranged at both ends of the bottom frame and the top frame along the first direction, and each side frame is respectively connected to the top frame and the bottom frame, so that the bottom frame, the two side frames, and the top frame enclose the installation space.

[0029] In the sewage interception device for water conservancy projects in this embodiment, by setting the first driving component 21 to drive the plurality of grating bars 22 to move along the first direction, the sundries blocked by the grating bars 22 can be dragged and loosened. Thus, it is convenient for the sewage cleaning member 32 to clean the sundries on the grating bars 22, which is beneficial to improving the cleaning effect.

[0030] In this embodiment, the grating bar 22 has a first end and a second end along the second direction, and the second direction is orthogonally arranged with the first direction. The support frame 1 has a guide rail 11 extending along the first direction. The first ends of the plurality of grating bars 22 are all slidably arranged on the guide rail 11, and the second ends of the plurality of grating bars 22 are all connected to the first driving component 21.

[0031] Specifically, the guide rail 11 is located at the bottom of the support frame 1. The first end of the grating bar 22 is provided with a guide hole, and the guide rail 11 penetrates through the guide hole. When driving the grating bar 22 along the first direction, the guide rail 11 can guide the grating bar 22 through the cooperation of the guide hole and the guide rail 11.

[0032] It can be understood that by setting the guide rail 11 on the support frame 1 to guide the grating bar 22, the first driving component 21 can drive the grating bar 22 to move stably along the first direction.

[0033] In this embodiment, as Figures 2 to 4As shown, each second end of the grid bar 22 has a guide pin 221; the first driving member 21 includes a first driving part 211 and a driving plate 212. The first driving part 211 is arranged on the support frame 1; the driving plate 212 is arranged at the output end of the first driving part 211. A plurality of guide grooves 2121 are arranged on the driving plate 212. The guide grooves 2121 extend along the third direction and are inclined relative to the third direction. The third direction is orthogonal to the first direction and the second direction. The plurality of guide pins 221 are inserted into the guide grooves 2121 one by one and are slidable relative to the guide grooves 2121. The first driving part 211 is used to drive the driving plate 212 to move along the third direction so as to drive the grid bar 22 to slide along the guide rail 11 through the driving plate 212.

[0034] For example, the first driving part 211 can be a hydraulic cylinder or a pneumatic cylinder, etc. The specific form of the first driving part 211 can be selected according to needs and is not limited here.

[0035] Specifically, the grid bar 22 is arranged vertically, that is, the second direction is the vertical direction. The guide pin 221 is located at the top of the grid bar 22. The first driving part 211 and the driving plate 212 can be arranged at the top of the support frame 1 to facilitate connection with the guide pin 221. Further, a guiding structure can be arranged between the driving plate 212 and the support frame 1 to guide and support the driving plate 212 when the driving plate 212 moves, so as to facilitate the stable movement of the driving plate 212. The specific form of the guiding structure can be selected according to needs and will not be elaborated here.

[0036] It can be understood that by arranging the guide grooves 2121 on the driving plate 212, the guide pins 221 on the grid bar 22 are located in the guide grooves 2121, and the guide grooves 2121 are inclined relative to the third direction. Therefore, when the first driving part 211 drives the driving plate 212 to move along the third direction, the driving plate 212 can apply a component force along the first direction to the grid bar 22 through the guide pin 221, so as to drive the grid bar 22 to move along the first direction. When the driving plate 212 moves in the reverse direction, it can drive the grid bar 22 to move in the reverse direction.

[0037] In this embodiment, as Figure 2 shown, the plurality of guide grooves 2121 are divided into two groups along the first direction. The two groups of guide grooves 2121 are symmetrically distributed on the driving plate 212, and the inclination directions of the two groups of guide grooves 2121 are opposite.

[0038] Specifically, the guiding directions of the guiding grooves 2121 within the same group are the same, while the directions of the guiding grooves 2121 in different groups are opposite. By driving the driving plate 212 with the first driving component 21, the driving plate 212 can drive the two groups of grating bars 22 to move in different directions. When driving the two groups of grating bars 22 to move towards each other, the sundries on both sides in the first direction can be converged towards the middle to loosen the sundries. When driving the two groups of grating bars 22 to move away from each other, the sundries on both sides can be separated. Both loosening the sundries and separating the sundries are beneficial for cleaning the sundries through the cleaning component 32.

[0039] In this embodiment, the cleaning component 32 includes a bottom plate and a scraping plate. The bottom plate is arranged at the output end of the second driving component 31, and the scraping plate is arranged on one side of the bottom plate adjacent to the grating bars 22.

[0040] For example, the part of the scraping plate for scraping the sundries can be provided with an inclined surface to improve the scraping effect of the scraping plate. Teeth can also be arranged at the scraping part of the scraping plate to scrape the sundries through the teeth.

[0041] It can be understood that by setting the bottom plate, the supporting force for the scraping plate can be improved, facilitating the scraping of the sundries by the scraping plate.

[0042] In this embodiment, leakage holes are arranged on the bottom plate. The cleaning component 32 further includes side plates. The side plates are arranged on the circumferential outer edge of the bottom plate, and both ends of the side plates along the circumferential direction of the bottom plate edge are correspondingly connected to both ends of the scraping plate one by one.

[0043] By arranging leakage holes on the bottom plate, the resistance during the movement of the scraping plate can be reduced. By arranging side plates on the outer peripheral edge of the bottom plate, a cavity can be formed by the bottom plate, the side plates and the scraping plate. The sundries scraped from the grating bars 22 by the scraping plate can be accumulated in the cavity, thereby reducing the shedding of the sundries.

[0044] In this embodiment, as Figure 1 and Figure 2 shown, the second driving component 31 includes a second driving member 311, a lead screw 312 and a slider 313. The second driving member 311 is arranged on the support frame 1. The lead screw 312 is arranged vertically. One end of the lead screw 312 is connected to the output end of the second driving member 311, and the other end of the lead screw 312 is rotatably connected to the support frame 1. The slider 313 is threadedly connected to the lead screw 312 and is connected to the cleaning component 32.

[0045] For example, the second driving member 311 can be a motor, and the rotation of the output shaft of the motor can drive the rotation of the lead screw 312.

[0046] Specifically, as Figure 2As shown, the second driving component 31 further includes a guide rod 314. The guide rod 314 is arranged on the support frame 1 and is located at one end of the dirt cleaning component 32 away from the lead screw 312. The guide rod 314 slidably penetrates through the dirt cleaning component 32. While guiding the dirt cleaning component 32, it can also cooperate with the lead screw 312 to stably support the dirt cleaning component 32. Further, support blocks are arranged on both sides of the support frame 1 along the first direction. The end of the lead screw 312 is rotatably connected to one support block, and one end of the guide rod 314 is fixed to the other support block. By arranging the support blocks, it is convenient for the installation of the lead screw 312 and the guide rod 314.

[0047] It can be understood that when dirt cleaning is required, the second driving member 311 drives the lead screw 312 to rotate. The lead screw 312 drives the slider 313 to move along the lead screw 312, so as to drive the dirt cleaning component 32 to move through the slider 313. When cleaning, the dirt cleaning component 32 is driven to move from bottom to top. Thus, the sundries removed from the grid bars 22 can fall onto the dirt cleaning component 32, which is convenient for centralized treatment of the sundries.

[0048] In this embodiment, as Figure 1 and Figure 2 shown, the water conservancy project trash rack device further includes a dirt blowing component 4. The dirt blowing component 4 is arranged on the support frame 1, and the dirt blowing component 4 is used to blow high-pressure gas to the grid bars 22.

[0049] Specifically, the dirt blowing component 4 is arranged on the side of the support frame 1 away from the dirt cleaning component 32. When the dirt blowing component 4 blows high-pressure gas towards the grid bars 22, the sundries can be loosened towards the side of the dirt cleaning component 32, so that it is convenient for the dirt cleaning component 32 to remove the sundries on the grid bars 22.

[0050] In this embodiment, as Figure 1 、 Figure 2 and Figure 5 shown, the dirt blowing component 4 includes a third driving component 41, an air pipe 42 and a nozzle 43. The third driving component 41 is arranged on the support frame 1; the air pipe 42 is rotatably arranged on the support frame 1 and is connected to the third driving component 41. The air pipe 42 is connected to a high-pressure air source, and the third driving component 41 is used to drive the air pipe 42 to rotate. The nozzle 43 is arranged on the side wall of the air pipe 42 to blow air to the grid bars 22 through the nozzle 43.

[0051] For example, by arranging bearings, the air pipe 42 can be rotatably connected to the support frame 1 through the bearings.

[0052] Multiple air pipes 42 can be arranged, and nozzles 43 are correspondingly arranged on each air pipe 42. Adjacent two air pipes 42 can be connected through a transmission mechanism. For example, the transmission mechanism can be a belt transmission mechanism.

[0053] When it is necessary to remove the debris on the grid bars 22, an external high-pressure gas source is used to supply gas to the gas pipe 42. The gas in the gas pipe 42 is ejected through the nozzle 43, and the gas is blown towards the grid bars 22, so that the debris on the grid bars 22 can be blown in a direction away from the grid bars 22. Thus, it is convenient for the cleaning member 32 to clean the debris. While the nozzle 43 is blowing air, the third driving member 41 can drive the gas pipe 42 to rotate, so that the angle at which the nozzle 43 blows gas towards the grid bars 22 can be changed, and the debris on the grid bars 22 can be blown from different directions, which is beneficial to making the debris better separated from the grid bars 22.

[0054] In this embodiment, as Figure 2 and Figure 5 shown, the third driving member 41 includes a rack 411 and a gear 412. The rack 411 is arranged on the outer peripheral surface of the gas pipe 42. The rack 411 is L-shaped. One end of the rack 411 is connected to the grid bar 22, and the other end of the rack 411 meshes with the gear 412.

[0055] For example, two groups of gas pipes 42 can be provided. In each group of gas pipes 42, two adjacent gas pipes 42 are connected by a belt transmission mechanism. One of the gas pipes 42 in each group of gas pipes 42 is connected to the rack 411 through the gear 412. Each group of gas pipes 42 is respectively connected to a third driving member 41.

[0056] Specifically, one end of the rack 411 is connected to the guide pin 221 of the grid bar 22. When the guide pin 221 moves in the first direction, it can drive the rack 411 to move in the first direction.

[0057] It can be understood that by setting the L-shaped rack 411 and connecting one end of the rack 411 to the grid bar 22 and the other end to mesh with the gear 412, when the grid bar 22 drives the rack 411 to move in the first direction, the rack 411 drives the gear 412 to rotate, so that the gas pipe 42 can be driven to rotate through the gear 412.
