Description

Technical Field

[0001] This utility model relates to a trash rack structure for an underwater water inlet. It is applicable to the field of building construction technology. Background Technology

[0002] Currently, trash racks are required in river and reservoir channels to filter larger impurities in the water flow and prevent blockages. The conventional arrangement for trash racks at water inlets involves setting up trash rack slots on both sides of the channel, lifting the trash racks using opening and closing equipment, and then securing them into the slots. However, for water intake structures in reservoirs, where the intake is located underwater, it is inconvenient to install trash rack slots at the intake, making it difficult to insert the trash racks directly into the intake. Furthermore, due to short reservoir emptying times or the inability to empty the reservoir, some trash racks cannot be installed on dry ground, necessitating underwater installation, which presents significant construction challenges. Utility Model Content

[0003] The technical problem to be solved by this utility model is: In order to solve the above-mentioned technical problem, this utility model provides a trash rack structure for an underwater water inlet.

[0004] The technical solution adopted in this utility model is: a trash rack structure for an underwater water inlet, having:

[0005] The main body of the trash rack is located inside the water inlet. Both ends of the trash rack are equipped with connecting plates, and the connecting plates have mounting holes.

[0006] The mounting plate is positioned inside the inlet and mates with the connecting plates at both ends of the trash rack body. Fixing bolts are installed on the mounting plate at positions corresponding to the mounting holes on the connecting plates, and nuts are installed on the fixing bolts passing through the mounting holes. Thus, during inlet construction, the mounting plate is fixed inside the inlet, facilitating the installation of the trash rack body at the inlet location. This allows the mounting holes on the connecting plates on both sides of the trash rack body to mate with the fixing bolts on the mounting plates on both sides of the inlet, and the trash rack body is installed at the inlet by installing and tightening the nuts on the fixing bolts passing through the connecting plates.

[0007] A first frame plate is installed between the connecting plates at both ends of the trash rack body, and a second frame plate is installed on the trash rack body at a position corresponding to the first frame plate. Reinforcing ribs are installed between the first and second frame plates. This effectively enhances the structural strength of the trash rack body.

[0008] The main body of the trash rack is welded together from at least two vertical bars and at least two horizontal bars.

[0009] The main body of the trash rack is composed of at least two trash rack units. Thus, when the inlet size is large, multiple trash rack units can be installed at corresponding positions at the inlet to form the main body of the trash rack, enabling the segmented manufacturing, transportation, and installation of the main body of the trash rack.

[0010] The fixing bolts are arranged along the axial direction of the inlet. In this way, when the trash rack body is installed in the inlet and trash-blocking operation is carried out, the fixing bolts are subjected to axial pressure and are not easily damaged.

[0011] The inlet is a concrete structure, and a first anchor bar is fixedly installed on the mounting plate. The first anchor bar can be anchored into the concrete structure. In this way, the mounting plate can be fixed to the concrete structure through the first anchor bar.

[0012] The concrete structure has a first concrete structure, in which a water supply pipe is installed at a position corresponding to the water inlet, and a second concrete structure is formed on both sides of the water inlet in the first concrete structure. A second anchor bar is arranged in the second concrete structure and is anchored into the first concrete structure.

[0013] The first concrete structure has a base plate at the bottom of the water inlet, and a third anchor bar is installed on the base plate and anchored into the first concrete structure.

[0014] A baffle is installed at the water inlet of the first concrete structure to seal the inlet. The baffle is removed after the second concrete structure and the installation plate are completed. In this way, after the first concrete structure is completed, the baffle at the water inlet can be easily sealed to prevent water from flowing into the inlet and affecting subsequent construction. Personnel can enter and carry out construction through the outlet end of the inlet.

[0015] A construction method for a trash rack structure for an underwater water inlet, using the aforementioned trash rack structure for an underwater water inlet:

[0016] During the low water level period, the construction of the first concrete structure is completed, a water supply pipe is pre-embedded at the water inlet of the first concrete structure, and a second anchor bar is pre-embedded at the location of the second concrete structure during the construction of the first concrete structure. The bottom plate with the third anchor bar installed is installed at the bottom of the water inlet and the third anchor bar is anchored into the first concrete structure.

[0017] After the first concrete structure is completed, the baffle is installed at the water inlet of the first concrete structure.

[0018] The second concrete structure is constructed at both sides of the inlet, and the second concrete structure is fixedly connected to the first concrete structure by the second anchor bar.

[0019] During the construction of the second concrete structure, the mounting plate is installed on the second concrete structure, and the first anchor bar is anchored into the second concrete structure.

[0020] The main body of the trash rack is transported to the inlet position through the water supply pipe. The main body of the trash rack is placed on the mounting holes on the connecting plates at both ends of the trash rack and the corresponding positions of the fixing bolts on the mounting plates. After the fixing bolts pass through the connecting plates, nuts are installed on the fixing bolts and tightened.

[0021] Remove the baffle at the inlet. Thus, after completing the first concrete structure and water pipe construction during the low water level period, the baffle at the inlet effectively seals it off, preventing water from flowing into the inlet after the water level rises and affecting construction inside. Personnel can then enter the inlet through the outlet of the water pipe to carry out the construction of the main body of the trash rack, achieving dry-ground installation of the trash rack.

[0022] The beneficial effects of this utility model are as follows: This utility model completes the construction of the first concrete structure when the water level in the reservoir is low, reserving an inlet, and installing a baffle at the corresponding position of the inlet on the first concrete structure. This facilitates preventing water from flowing into the inlet when the water level in the reservoir rises, thus avoiding any impact on the construction of the water supply pipe and the main body of the trash rack inside the inlet. Furthermore, by pre-embedding second anchor bars on both sides of the inlet during the construction of the first concrete structure, this utility model facilitates personnel entering the inlet position through the water supply pipe outlet to carry out the construction of the second concrete structure when the baffle blocks the inlet. During the construction of the second concrete structure, the first anchor bar on the mounting plate is embedded into the second concrete structure, thus achieving the installation of the mounting plate... The trash rack is fixedly installed at the water inlet. This invention transports individual trash rack units to the water inlet via the water outlet of a water pipe, and then installs them on the mounting plates on both sides. The fixing bolts on the mounting plates pass through the mounting holes on the connecting plates at both ends of the trash rack body, and nuts are installed on the fixing bolts extending out of the mounting holes, thus installing the trash rack unit at the water inlet. This invention also assembles multiple trash rack units at the water inlet to form the trash rack body, enabling the trash rack body to intercept trash at the water inlet. Furthermore, this invention enhances the structural strength of the trash rack body by installing a first frame plate between the connecting plates at both ends of the trash rack body and installing reinforcing ribs between the first frame plate and the trash rack body.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0031] This utility model is a trash rack structure for an underwater water inlet.

[0032] In this embodiment, a first concrete structure 1 is constructed during the low water level period of the reservoir. During the construction of the first concrete structure 1, an inlet is reserved, and second anchor bars 3 are pre-embedded at both sides of the inlet. After the construction of the first concrete structure 1 is completed, a baffle 7 is installed at the inlet position on the first concrete structure 1. In this way, water flow into the inlet can be effectively prevented after the water level of the reservoir rises during the construction process inside the inlet.

[0033] In this embodiment, the water supply pipe 2 is constructed at the water inlet of the first concrete structure 1, so that personnel can enter the water inlet location through the water supply pipe 2.

[0034] In this embodiment, installation positions for the second concrete structure 4 are reserved on both sides of the water inlet in the first concrete structure 1, and second anchor bars 3 are pre-embedded in the first concrete structure 1 at the installation positions of the second concrete structure 4. Thus, after personnel enter the water inlet position, they carry out the construction of the second concrete structure 4, and the second concrete structure 4 is fixedly connected to the first concrete structure 1 under the action of the second anchor bars 3.

[0035] In this embodiment, an mounting plate 9 is installed on the second concrete structure 4, and a first anchor bar 8 is fixedly installed on the mounting plate 9. During the construction of the second concrete structure 4, the mounting plate 9 is installed on the second concrete structure 4, so that the first anchor bar 8 is anchored into the second concrete structure 4, thereby fixing the mounting plate 9 to the second concrete structure 4. Fixing bolts 10 are fixedly installed on the mounting plate 9, and the fixing bolts 10 are arranged along the axial direction of the water inlet. When water flows in the water inlet, the mounting plate 9 can alleviate the scouring of the second concrete structure 4.

[0036] In this embodiment, a trash rack body 11 is installed between the mounting plates 9 on both sides of the water inlet. The trash rack body 11 is composed of at least two trash rack units, which facilitates the transportation of the trash rack units to the water inlet position via the water supply pipe 2, and the installation of the trash rack units at the water inlet to form the trash rack body 11.

[0037] In this embodiment, connecting plates 12 are installed at both ends of the trash rack body 11, and mounting holes are made on the connecting plates 12 at positions corresponding to the fixing bolts 10. When the trash rack body 11 is arranged at the water inlet, the trash rack body 11 is fixedly installed at the water inlet by passing the fixing bolts 10 on the mounting plate 9 through the mounting holes on the connecting plate 12 and installing nuts 18 on the fixing bolts 10.

[0038] In this embodiment, the mounting plate 9 is installed on the water-facing side of the second concrete structure 4, and the fixing bolts 10 on the mounting plate 9 are arranged along the axial direction of the water inlet. Thus, when the trash rack body 11 is installed on the mounting plate 9, the trash rack body 11 is located on the water-facing side of the second concrete structure 4. Both the trash rack body 11 and the mounting plate 9 can provide erosion protection for the second concrete structure 4, and at this time, the fixing bolts 10 are only subjected to axial pressure, making them less prone to damage.

[0039] In this embodiment, a first frame plate 15 is installed between the connecting plates 12 at both ends of the trash rack body 11, and a second frame plate 16 is installed on the trash rack body 11 at a position corresponding to the first frame plate 15. A reinforcing rib 17 is installed between the first frame plate 15 and the second frame plate 16. The trash rack body 11 is welded together from at least two vertical grid bars 13 and at least two horizontal grid bars 14. This greatly enhances the structural strength of the trash rack body 11.

[0040] In this embodiment, a base plate 6 is formed at the bottom of the water inlet in the first concrete structure 1, and a third anchor bar 5 is installed on the base plate 6. The third anchor bar 5 is anchored into the first concrete structure 1.

[0041] In this embodiment, the first concrete structure 1 has a slope at the bottom of the inlet that slopes outwards. By creating the slope, the diameter of the inlet is reduced, which increases the resistance to fluid flow and can reduce the pressure in the pipe. Furthermore, when the fluid passes through the reduced diameter, the flow velocity increases, but the pressure decreases at the same time, which helps to reduce the noise generated by the fluid impacting the pipe wall.

[0042] The construction method in this embodiment is as follows:

[0043] During the low water level period, the construction of the first concrete structure 1 is completed. A water supply pipe 2 is pre-embedded at the water inlet of the first concrete structure 1. During the construction of the first concrete structure 1, a second anchor bar 3 is pre-embedded at the location of the second concrete structure 4. The bottom plate 6 with the third anchor bar 5 is installed at the bottom of the water inlet and the third anchor bar 5 is anchored into the first concrete structure 1.

[0044] After the first concrete structure 1 is completed, the baffle 7 is installed at the water inlet of the first concrete structure 1.

[0045] The second concrete structure 4 is constructed at both sides of the inlet, and the second concrete structure 4 is fixedly connected to the first concrete structure 1 by the second anchor bar 3.

[0046] During the construction of the second concrete structure 4, the mounting plate 9 is installed on the second concrete structure 4, and the first anchor bar 8 is anchored into the second concrete structure 4.

[0047] The main body 11 of the trash rack is transported to the inlet position through the water supply pipe 2. The main body 11 of the trash rack is arranged at the corresponding positions of the mounting holes on the connecting plates 12 at both ends of the trash rack 11 and the fixing bolts 10 on the mounting plate 9. After the fixing bolts 10 pass through the connecting plates 12, nuts 18 are installed on the fixing bolts 10 and tightened.

[0048] Remove the baffle at the water inlet 7.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
