[0029] like Figure 1 As shown, the utility model provides a water intake head box 1 component, which is composed of two water inlet boxes spliced ​​together, and the water inlet box includes:

[0030] The box body 1 has a rectangular cross-section and an open top. The upper side wall of the box body 1 is provided with a water inlet 2 and the lower side wall of the box body 1 is provided with a water outlet 3.

[0031] A water guide structure 5 having a triangular cross section and disposed at one end of the water inlet tank;

[0032] A box cover 4 is provided on the top of the box body 1;

[0033] Among them, one end of the water inlet box away from the water guide structure 5 is spliced ​​to form the water intake head box body 1 component.

[0034] In this technical solution, the length direction of the two water inlet tanks is aligned with the direction of water flow. The two water inlet tanks can be connected by overlapping a step structure with a positioning column, or by providing a positioning groove on one water inlet tank and a positioning protrusion on the other water inlet tank, with the positioning protrusion snapping into the positioning groove. The water guide structure 5 is provided at both ends of the water intake head box 1 component. The box cover 4 can be provided with a lifting ring to facilitate the lifting of the box cover 4. The water guide structure 5 is integrally formed with the box body 1. In this utility model, the box body 1, water guide structure 5, and box cover 4 are all cast from concrete.

[0035] External water enters the box body 1 from the water inlet 2 and is discharged through the water outlet pipe connected to the water outlet 3.

[0036] In another technical solution, a grille 11 is provided at the water inlet 2. The grille 11 is provided at the water inlet 2 to prevent debris from entering the box body 1 through the water inlet 2.

[0037] In another technical solution, the grille 11 comprises a plurality of baffles 12 and a plurality of curved gratings 13. The baffles 12 are arranged in parallel at equal intervals and at a 45-degree angle to the longitudinal direction of the tank 1. The curved gratings 13 are positioned between adjacent baffles 12. The baffles 12 align the water inlet direction of the tank 1 with the water flow, improving the interception of floating debris. One end of the curved grating 13 is connected to the beginning of a baffle 12, and the other end is connected to the end of an adjacent baffle 12. This helps increase the filtration area.

[0038] In another technical solution, a steel casing is provided at the water inlet 2. The provision of the steel casing facilitates connection with an external water outlet pipe.

[0039] In another technical solution, a sand settling structure is provided inside the box 1, and the sand settling structure includes:

[0040] A support edge is provided on the inner wall of the box body 1 along the length direction of the box body 1, and the support edge is provided below the water inlet 2;

[0041] The cross section of the sand retaining plate 9 is inverted V-shaped. A plurality of water inlet holes 10 are provided on the upper portion of the sand retaining plate 9 , and one end of the sand retaining plate 9 in the opening direction abuts against the support edge.

[0042] The support edge can support the sand shield 9 so that the sand shield 9 can be detachably connected. On the one hand, the sand shield 9 can play the role of settling large particles of debris so that the large particles of debris enter the accommodation space defined by the angle between the sand shield 9 and the side wall of the box body 1. On the other hand, it can increase the uniformity of water inflow into the water inlet 2 to avoid the occurrence of excessive water flow in a certain water inlet 2 that may attract aquatic organisms.

[0043] In another technical solution, the box body 1 is provided with a sludge discharge port, which is located above the support edge, and a sealing plate is provided at the sludge discharge port. The sealing plate can be fixedly connected to the box body 1 by means of bolts.

[0044] In another technical solution, the water guide structure 5 is a hollow structure. In order to reduce the weight of the component so as to facilitate lifting, the water guide structure 5 is hollow. After the lifting and installation are completed, concrete is poured into the water guide structure 5 to increase the counterweight.

[0045] In another technical solution, the bottom plate width of the box body 1 is greater than the width of the box body 1 to form an expanded bottom plate 8 on both sides of the box body 1. By adding the expanded bottom plate 8, when backfilling gravel, it presses on the expanded bottom plate 8, which can increase the stability of the component in water.

[0046] In another technical solution, the water inlet tank on the left is provided with a step joint 6 at the expanded bottom plate 8 away from the end of the water guide structure 5, and the step joint 6 is provided with a first circular hole 7. The expanded bottom plate 8 of the water inlet tank on the right is provided with a second circular hole. When the step joint 6 is overlapped on the expanded bottom plate 8 of the water inlet tank on the right, the first circular hole 7 and the second circular hole are positioned relative to each other. The step joint 6 is used to splice the water inlet tank on the left with the water inlet tank on the right, which can play an auxiliary positioning role. Specifically, two positioning piles can be installed in the foundation pit. First, the water inlet tank on the right is hoisted to the foundation pit, and the second circular hole passes through the two positioning piles. Then, the water inlet tank on the left is hoisted to the foundation pit, and the first circular hole 7 passes through the two positioning piles to achieve the splicing of the two water inlet tanks.

[0047] The method of using the present utility model is as follows: two water inlet tanks are cast with reinforced concrete on the shore, the water inlet 2, the water outlet 3 and the top of the box body 1 are sealed with steel plates, the right water inlet tank is hoisted to the foundation pit, and then the left water inlet tank is hoisted to the foundation pit, the steel plates at the water inlet 2, the water outlet 3 and the top of the box body 1 are cut off, concrete is poured into the water guide structure 5 and the bottom of the box body 1, the sand settling structure is hoisted into the box body 1, and then the cover plate is hoisted to the top of the water inlet tank, and the foundation pit is backfilled to complete the installation of the components.

[0048] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
