[0040] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0041] like Figure 1 As shown, a riverbed water intake trash rack device includes a trash rack pipe section 3, a trash-blocking component 4 and a mounting component. The trash rack pipe section 3 and the trash-blocking component 4 are both connected to the mounting component. The trash rack pipe section 3 has a plurality of first trash-blocking holes, and the trash-blocking component 4 has a plurality of second trash-blocking holes. The first trash-blocking holes and the second trash-blocking holes are oriented in different directions. By sequentially connecting the trash rack pipe section 3, the trash-blocking component 4 and the mounting component to form a whole, and based on the structural characteristics of the first trash-blocking holes and the second trash-blocking holes oriented in different directions, water can be inletted from multiple directions, the risk of insufficient water intake due to silting of the grid is reduced, and the reliability of water intake is improved; at the same time, by providing the first trash-blocking holes and the second trash-blocking holes, the defects of the riverbed water intake trash rack in the prior art that a large number of steel bars or flat irons need to be welded when intercepting trash can be overcome, resulting in a large workload for final processing and welding, resulting in the inability to guarantee the quality of the welds, and poor structural durability.

[0042] Specifically, the trash screen pipe segments 3, the trash retaining components 4 and the installation components adopt the same coating process, which ensures the coating quality, reduces rust, improves the durability of the structure, and can reduce the breeding of shellfish.

[0043] like Figure 1 As shown, the installation component includes two steel pipe sections 2, which are respectively connected to the two ends of the trash screen pipe section 3, and the trash blocking component 4 is connected to the end of the steel pipe section 2 away from the trash screen pipe section 3. By connecting the two steel pipe sections 2 to the two ends of the trash screen pipe section 3 respectively, and connecting the trash blocking component 4 to the end away from the trash screen pipe section 3, a whole capable of multi-directional water intake and trash blocking is formed, thereby improving the efficiency of water intake and trash blocking.

[0044] like Figure 2 and Figure 4 As shown, in a preferred embodiment, the riverbed water intake trash rack device further includes a plurality of flange connectors 5, and the flange connectors 5 are connected between the trash rack pipe section 3 and the steel pipe section 2; in another preferred embodiment, the flange connectors 5 are connected between the trash retaining component 4 and the steel pipe section 2; in a further preferred embodiment, the flange connectors 5 are connected between the trash rack pipe section 3 and the steel pipe section 2 and the flange connectors 5 are connected between the trash retaining component 4 and the steel pipe section 2. The trash rack pipe section 3 and the steel pipe section 2, as well as the trash retaining component 4 and the steel pipe section 2 can be connected by the flange connectors 5, thereby improving the stability of the structure and preventing loosening; at the same time, replacement is convenient and maintenance is convenient.

[0045] like Figure 1-Figure 3 As shown, the trash screen pipe segment 3 is tubular, and the trash screen pipe segment 3 is arranged correspondingly to the steel pipe segment 2. The trash screen pipe segment 3 is arranged correspondingly to the steel pipe segment 2 to achieve a good fit between the two and improve the stability of the overall connection.

[0046] like Figure 4 and Figure 5 As shown, the dirt retaining member 4 is a grid plate, and the dirt retaining member 4 is arranged correspondingly to the steel pipe section 2 far away from the dirt retaining grid pipe section 3. The dirt retaining member 4 is arranged as a grid plate to improve the dirt discharge effect, and the dirt retaining member 4 is arranged correspondingly to the steel pipe section 2 far away from the dirt retaining grid pipe section 3 so that the two can be arranged in a close fit, thereby improving the stability of the connection.

[0047] like Figure 1As shown, the riverbed water intake trash rack device also includes a steel structure frame 1, which is provided with a plurality of longitudinal beams and a plurality of transverse beams. One end of the longitudinal beam is inserted into the riverbed, and the transverse beam is used to connect two adjacent longitudinal beams. The longitudinal beams and the transverse beams are sequentially connected to form a tic-tac-toe structure. By carrying the steel structure frame 1 and forming a tic-tac-toe structure, the whole formed by the trash rack pipe section 3, the steel pipe section 2 and the trash-blocking component 4 can be erected on the steel structure frame 1. At the same time, the tic-tac-toe structure has a relatively stable structural characteristic, which improves the overall rigidity and stability.

[0048] Specifically, the steel pipe piles can be generally implemented by a pile-driving ship on the water, and then the steel structure frame 1 is implemented by underwater operation. The trash screen pipe segment 3 and the trash blocking component 4 are connected and fixed to the steel pipe segment 2 through the flange connector 5, and are installed on the steel structure pile frame by a water hoisting ship, and can be fixed underwater by means of a clamp or the like.

[0049] like Figure 1 As shown, the length of the trash screen pipe segment 3 in the horizontal direction is less than the length of the distance between two adjacent longitudinal beams in the horizontal direction. Because the structural strength of the trash screen pipe segment 3 is weak and cannot directly contact the steel structure frame 1, by setting the length of the trash screen pipe segment 3 in the horizontal direction to be less than the length of the distance between two adjacent longitudinal beams in the horizontal direction, the trash screen pipe segment 3 is prevented from directly contacting the steel structure frame 1, so that the steel pipe segment 2 acts as a supporting medium, thereby improving the overall structural stability of the trash screen pipe segment 3, the steel pipe segment 2 and the trash blocking component 4.

[0050] like Figure 6 As shown, the size of the first and second trash-blocking holes is set to 100 mm×100 mm, the chamfer radius of the corner is 25 mm, and the net distance between the holes is 50 mm. This arrangement can improve the effect of sewage discharge.

[0051] The first trash-blocking hole and the second trash-blocking hole are both arranged in a square shape, so that the effect of draining the dirt can be improved.

[0052] Specifically, in the embodiment of the utility model, the first and second square holes of the trash grille pipe section 3 and the trash grille component 4 are pre-opened on the steel plate by a CNC cutting machine, and then the steel plate with the holes is rolled into a tube by a plate rolling machine, and welded to the flange connector 5. This method is convenient for construction. The use of CNC cutting technology and plate rolling machines can improve efficiency in the factory to reduce the production cycle, and the control of precision is more accurate, avoiding a lot of welding work, saving manpower and material resources. At the same time, the quality is guaranteed. Compared with the traditional grille bar welding process, the integrated cutting and forming structure has a more controllable construction quality, uniform holes, good flatness, and is not easy to accumulate.

[0053] A water intake head structure includes the above-mentioned riverbed water intake trash rack device, which forms a whole by connecting the trash rack pipe section 3, the trash blocking component 4 and the installation component in sequence, and based on the structural characteristics of the different orientations of the first trash blocking hole and the second trash blocking hole, realizes multi-directional water intake, reduces the risk of insufficient water intake due to grid siltation, and improves water intake reliability; at the same time, by providing the first trash blocking hole and the second trash blocking hole, it is possible to overcome the defects of the riverbed water intake trash rack in the prior art that a large number of steel bars or flat irons need to be used for welding when blocking trash, resulting in a large workload for final processing and welding, resulting in the inability to guarantee the quality of the welds, and poor structural durability.

[0054] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
