Description

Technical Field

[0001] This utility model relates to a trash rack structure for a reservoir water intake. It is applicable to the field of water conservancy and hydropower equipment technology. Background Technology

[0002] A trash rack is a frame structure installed before the water inlet to block debris (generally referred to as sludge) such as aquatic plants and driftwood carried by the water flow. Trash racks are usually fixed at the water inlet by bolts or welding; however, this installation method makes it inconvenient to install and remove the trash rack.

[0003] In recent years, many newly constructed reservoir projects have integrated flood control, water supply, irrigation, and power generation. Taking advantage of the high water levels in these reservoirs, small hydroelectric generator units are added to provide additional power generation, in addition to flood control, irrigation, and ecological environment improvement. These small generator units typically have trash racks at their intakes to protect the units. The intakes are characterized by a small number of orifices, small orifice sizes, high water levels, and limited maintenance conditions. Conventional trash rack structures are not fully suitable for the trash rack arrangement requirements of high-head intakes for these small generator units. Utility Model Content

[0008] The locking structure is arranged on both sides of the door slot. The locking structure has a fixed beam that is fixedly installed on the door slot. A locking beam that slides with the fixed beam is installed on the fixed beam. A slot is provided on the side wall of the main body of the trash rack at the position corresponding to the locking beam.

[0009] The main body of the trash rack is composed of at least two trash rack units connected vertically. Each trash rack unit has two supporting longitudinal beams. The slot is located in the middle of the two supporting longitudinal beams. At least two supporting crossbeams are connected between the two supporting longitudinal beams. Trash rack bars arranged along the direction of the supporting longitudinal beams are connected to the supporting crossbeams. A flow straightener is welded onto the trash rack bars. Adjacent trash rack units are connected by a connecting mechanism.

[0010] The supporting longitudinal beam has a third mounting hole at both its upper and lower ends. The connecting mechanism has a first mounting plate and a second mounting plate, with corresponding first and second mounting holes on the first and second mounting plates. When the first and second mounting plates are arranged on both sides of the supporting longitudinal beams of two adjacent trash rack units, the first mounting holes on the first and second mounting plates are located at positions corresponding to the third mounting holes at the lower end of the upper supporting longitudinal beam, and the second mounting holes on the first and second mounting plates are located at positions corresponding to the third mounting holes at the upper end of the lower supporting longitudinal beam. The first mounting plate, the supporting longitudinal beam, and the second mounting plate are connected by a first bolt.

[0011] A balance beam is installed at the lower end of the grab beam. Two pairs of fourth mounting plates are installed at the lower end of the balance beam. The fourth mounting plates have fourth mounting holes. The two pairs of fourth mounting plates are located at the corresponding positions of the two supporting longitudinal beams on the trash rack unit. Each pair of two fourth mounting plates is located on both sides of the supporting longitudinal beam. When the balance beam is arranged on the trash rack unit, the fourth mounting holes on the fourth mounting plates correspond to the third mounting holes at the upper end of the supporting longitudinal beams. The supporting longitudinal beams and the fourth mounting plates are connected by second bolts.

[0012] A fifth mounting plate is installed on the balance beam, and the fifth mounting plate has a fifth mounting hole. A sixth mounting plate is installed at the lower end of the grab beam on both sides of the lifting lug, and the sixth mounting plate has a sixth mounting hole. The fifth mounting hole and the sixth mounting plate are connected by a third bolt that passes through both the fifth mounting hole and the sixth mounting hole.

[0013] A guide post is installed at the upper end of the balance beam, and a guide tube is installed at the lower end of the grab beam at the position corresponding to the guide post. When the grab beam is installed on the balance beam, the guide tube is fitted onto the guide post.

[0014] The locking structure has fixed beams fixedly installed on the ground on both sides of the grab beam along the length of the grab beam. The fixed beams have sliding grooves arranged along the length of the grab beam. Locking beams are installed on the two fixed beams. The locking beams are arranged along the width of the grab beam. At the two ends of the lower end of the locking beams, sliders that can slide and engage with the sliding grooves on the two fixed beams are respectively installed. The trash rack unit is provided with a slot that can engage with the locking block.

[0017] A mounting bracket is installed on the side wall of the balance beam, and rollers that can roll in cooperation with the side wall of the door slot are installed on the mounting bracket. A rubber pad is placed between the mounting bracket and the balance beam.

[0018] The beneficial effects of this utility model are as follows: This utility model connects the individual trash rack units together via a connecting mechanism to form the main body of the trash rack, which is then inserted into the gate slot of the reservoir intake, facilitating the assembly and disassembly of the main body at the reservoir intake. This utility model facilitates the raising and lowering of the main body of the trash rack by installing a balance beam on the main body of the trash rack, installing a grab beam on the balance beam, and connecting the grab beam to the hoist. This utility model provides support for the balance beam as it moves within the gate slot, while also preventing wear on the balance beam. This utility model provides a locking structure on the ground of the gate slot, facilitating the removal of the main body of the trash rack from the gate when needed. When removing the trash rack from the trough, the hoist drives the grab beam and each individual trash rack to move upward. Then, by operating the locking beam, it moves on the moving beam to a position where it engages with the slot on the next trash rack. At this point, the locking structure fixes the trash rack and the trash rack below it. By disconnecting the previous trash rack from the next trash rack and disconnecting the balance beam from the previous trash rack and connecting it to the next trash rack, the previous trash rack can be disassembled. Then, by moving the locking beam on the fixed beam to a position where it does not engage with the slot on the next trash rack, and by continuing to operate the hoist, the next trash rack moves upward. This cycle can be repeated to remove each trash rack. Attached Figure Description

[0031] 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.

[0032] Example 1 is a trash rack structure for a reservoir intake, which has the following features:

[0033] The main body 1 of the trash rack is inserted into the door slot 7 from top to bottom;

[0034] The grab beam 2 is installed at the upper end of the trash rack body 1 and is connected to the hoist. The upper end of the grab beam 2 extends out of the gate slot 7.

[0035] The locking structure 6 is arranged on both sides of the gate slot 7. The locking structure 6 has a fixed beam 6-1 fixedly installed on the gate slot 7, and a locking beam 6-3 that slides on the fixed beam 6-1. The side wall of the trash rack body 1 is provided with a slot 1-5 at a position corresponding to the locking beam 6-3. In this way, by connecting the trash rack body 1, the balance beam 3 and the grab beam 2, it is convenient to move the trash rack body 1 within the gate slot 7 when the grab beam 2 is raised and lowered by the hoist, so as to realize the installation and disassembly of the trash rack body 1 at the water intake of the reservoir. When the hoist drives the grab beam 2 and the main body of the trash rack 1 to move within the gate slot 7, and the slot 1-5 on the main body of the trash rack 1 moves to the position corresponding to the locking beam 6-3 at the opening of the gate slot 7, the locking beam 6-3 is moved on the fixed beam 6-1 to the position where it engages with the slot 1-5. At this time, the main body of the trash rack 1 is fixed by the locking beam 6-3, which makes it easy to remove the grab beam 2 from the main body of the trash rack 1.

[0036] Example 2 is a trash rack structure for a reservoir intake. Based on Example 1, in this example: the trash rack body 1 is composed of at least two trash rack units 1-1 connected vertically. Each trash rack unit 1-1 has two supporting longitudinal beams 1-2. The slots 1-5 are provided on the two supporting longitudinal beams 1-2. At least two supporting crossbeams 1-3 are connected between the two supporting longitudinal beams 1-2. Trash rack bars 1-4 arranged along the direction of the supporting longitudinal beams 1-2 are connected to the supporting crossbeams 1-3. A flow straightening plate is welded on the trash rack bars 1-4. Adjacent trash rack units 1-1 are connected by a connecting mechanism.

[0037] The upper and lower ends of the supporting longitudinal beam 1-2 are each provided with a third mounting hole 1-6. The connecting mechanism has a first mounting plate 4 and a second mounting plate 5. The first mounting plate 4 and the second mounting plate 5 are each provided with a first mounting hole and a second mounting hole at corresponding positions. When the first mounting plate 4 and the second mounting plate 5 are arranged on both sides of the supporting longitudinal beam 1-2 of two adjacent trash rack units 1-1, the first mounting hole on the first mounting plate 4 and the second mounting plate 5 are located at the position corresponding to the third mounting hole 1-6 at the lower end of the upper supporting longitudinal beam 1-2, and the second mounting hole on the first mounting plate 4 and the second mounting plate 5 are located at the position corresponding to the third mounting hole 1-6 at the upper end of the lower supporting longitudinal beam 1-2. The first mounting plate 4, the supporting longitudinal beam 1-2, and the second mounting plate 5 are connected by a first bolt 1-7. In this way, the number of trash rack units 1-1 can be adjusted according to the actual situation of the reservoir intake so that the main body 1 of the trash rack can cover the reservoir intake. When two trash rack units 1-1 are connected, the first mounting plate 4 and the second mounting plate 5 are arranged on both sides of the corresponding two support longitudinal beams 1-2 on the two trash rack units 1-1. The two trash rack units 1-1 are connected by the first bolt 1-7 passing through the third mounting hole 1-6 at the lower end of the support longitudinal beam 1-2 on the previous trash rack unit 1-1 and the first mounting hole on the first mounting plate 4 and the second mounting plate 5, and by the first bolt 1-7 passing through the third mounting hole 1-6 at the upper end of the support longitudinal beam 1-2 on the next trash rack unit 1-1 and the second mounting hole on the first mounting plate 4 and the second mounting plate 5.

[0038] After the hoist drives the grab beam 2 and each trash rack unit 1-1 to move upward, the locking beam 6-3 is moved on the moving beam to a position where it engages with the slot 1-5 on the next trash rack unit 1-1. At this time, the locking structure 6 fixes the trash rack unit 1-1 and the trash rack unit 1-1 below it. By disconnecting the previous trash rack unit 1-1 from the next trash rack unit 1-1, the balance beam 3 is disconnected from the previous trash rack unit 1-1 and connected to the next trash rack unit 1-1, which facilitates the disassembly of the previous trash rack unit 1-1. Then, by moving the locking beam 6-3 on the fixed beam 6-1 to a position where it does not engage with the slot 1-5 on the next trash rack unit 1-1, and continuing to drive the hoist to move the next trash rack unit 1-1 upward, each trash rack unit 1-1 can be disassembled in this cycle.

[0039] Example 3 describes a trash rack structure for a reservoir intake. Based on Example 2, this example features a balance beam 3 installed at the lower end of the grab beam 2. Two pairs of fourth mounting plates 3-3 are installed at the lower end of the balance beam 3. Each fourth mounting plate 3-3 has a fourth mounting hole. The two pairs of fourth mounting plates 3-3 are located at corresponding positions on the two supporting longitudinal beams 1-2 of the trash rack unit 1-1. Each pair of four fourth mounting plates 3-3 is located on both sides of the supporting longitudinal beam 1-2. When the balance beam 3 is positioned on the trash rack unit 1-1, the fourth mounting holes on the fourth mounting plates 3-3 correspond to the third mounting holes 1-6 at the upper end of the supporting longitudinal beams 1-2. The supporting longitudinal beams 1-2 and the fourth mounting plates 3-3 are connected by second bolts 3-7. Thus, the connection between the balance beam 3 and the trash rack unit 1-1 is achieved by simultaneously passing the second bolts 3-7 through the third mounting holes 1-6 at the upper end of the supporting longitudinal beams 1-2 on the trash rack unit 1-1 and the fourth mounting holes on the fourth mounting plates 3-3 on the balance beam 3. Thus, the balance beam 3 is installed on the grab beam 2, and the balance beam 3 is connected to the trash rack unit 1-1 by the support longitudinal beams 1-2 arranged on both sides of the trash rack unit 1-1, so that the balance beam 3 and the trash rack unit 1-1 have higher connection strength and structural stability.

[0040] Example 4 is a trash rack structure for a reservoir intake. Based on Example 2, in this example: a fifth mounting plate 3-1 is installed on the balance beam 3, and the fifth mounting plate 3-1 has a fifth mounting hole. A sixth mounting plate 2-1 is installed at the lower end of the grab beam 2 on both sides of the lifting lug, and the sixth mounting plate 2-1 has a sixth mounting hole. The fifth mounting hole and the sixth mounting plate 2-1 are connected by a third bolt that passes through both the fifth mounting hole and the sixth mounting hole.

[0041] A guide post 3-2 is installed at the upper end of the balance beam 3, and a guide tube 2-2 is installed at the lower end of the grab beam 2 at a position corresponding to the guide post 3-2. When the grab beam 2 is installed on the balance beam 3, the guide tube 2-2 is fitted onto the guide post 3-2. Thus, the balance beam 3 and the grab beam 2 are connected by a third bolt that passes simultaneously through the fifth mounting hole of the fifth mounting plate 3-1 on the balance beam 3 and the sixth mounting hole of the sixth mounting plate 2-1 on the grab beam 2. The cooperation between the guide post 3-2 and the guide tube 2-2 guides the connection between the balance beam 3 and the grab beam 2.

[0042] Example 5 is a trash rack structure for a reservoir intake. Based on Example 2, in this example: the locking structure 6 has fixed beams 6-1 fixedly installed on the ground on both sides of the grab beam 2 along the length of the grab beam 2. The fixed beams 6-1 have sliding grooves 6-2 arranged along the length of the grab beam 2. Locking beams 6-3 are installed on the two fixed beams 6-1. The locking beams 6-3 are arranged along the width of the grab beam 2. At the two ends of the lower end of the locking beams 6-3, sliders that can slide and cooperate with the sliding grooves 6-2 on the two fixed beams 6-1 are respectively installed. The trash rack unit 1-1 is provided with a slot 1-5 that can cooperate with the locking beam 6-3.

[0043] Reinforcing ribs 6-4 are installed on both sides of the locking beam 6-3.

[0044] A handle 6-5 is installed on the locking beam 6-3. This allows personnel to operate the handle 6-5 to move the locking beam 6-3 on the fixed beam 6-1, where the slider on the locking beam 6-3 engages with the groove 6-2 on the fixed beam 6-1. When the locking beam 6-3 moves on the fixed beam 6-1 to the position where it engages with the slot 1-5 on the trash rack unit 1-1, the locking beam 6-3 effectively secures the trash rack unit 1-1, facilitating the removal of the trash rack unit 1-1 above it. The reinforcing rib 6-4 fixedly installed on the locking beam 6-3 enhances the structural strength of the locking beam 6-3.

[0045] Example 6 describes a trash rack structure for a reservoir intake. Based on Example 1, this example features: a mounting bracket 3-4 installed on the side wall of the balance beam 3; rollers 3-5 mounted on the mounting bracket 3-4 that can roll in conjunction with the side wall of the gate slot 7; and a rubber pad 3-6 placed between the mounting bracket 3-4 and the balance beam 3. This facilitates the movement of the balance beam 3 within the gate slot 7, provides support for the balance beam 3, and prevents wear on the balance beam 3.
