The other side of the separation frame 2 is processed to form an inclined edge, which is inclined towards the water inlet pipe 1 from top to bottom. A separation component 3 is arranged at the water inlet end of the separation frame 2. The side of the water inlet pipe 1 is installed with a collection component 4 through the separation component 3.

[0026] In this embodiment, when in use, with the partition frame 2 and the separation component 3 provided, water will flow into the water inlet pipe 1 through the partition frame 2. Meanwhile, through the separation component 3 provided, the separation component 3 will separate the garbage from the incoming water, so as to convey the water into the separation component 3, and then through the separation component 3 provided, the water will be sent into the collection component 4. Therefore, when removing the garbage, it is not necessary to disassemble the sewer. The components in the collection component 4 can be directly removed for cleaning, saving a lot of time and increasing the cleaning efficiency.

[0027] Refer to Figures 1-3 , the separation component 3 includes a separation net 5. The separation net 5 is installed at the entrance of the partition frame 2. A separation channel 6 is horizontally installed at the bottom side of the entrance of the partition frame 2. The separation channel 6 is inclined downward to the right and is connected to the top of the partition frame 2 through a fixing rod.

[0028] In this embodiment, through the separation net 5 provided and with an inclined setting, under the impact of the water flow, it will be sent into the separation channel 6 along the inclined separation net 5, thus preventing the garbage from blocking the entrance when the water enters and affecting the use of the hydraulic generator.

[0029] Refer to Figures 1-3 , a collection bin 7 is provided at the bottom end of the separation channel 6. A sealing plate 8 is installed at the top end of the collection bin 7. The sealing plate 8 is trapezoidally arranged, and a transfer pipe 9 is installed at the top end of the sealing plate 8.

[0030] In this embodiment, a submersible pump can be installed at the bottom side of the collection bin 7, and at the same time, a closed net is arranged outside the submersible pump to prevent the submersible pump from being blocked. After the screen outside the submersible pump is blocked, the submersible pump is turned off, and the garbage will automatically fall. Then, the submersible pump is made to spray water into the collection bin 7. Along with the upward flow of the water, the water in the separation channel 6 will be pushed into the transfer pipe 9, and at the same time, the garbage will be sent into the transfer pipe 9 along with the water flow, facilitating the transfer of the garbage.

[0031] Refer to Figures 1-3 , the collection component 4 includes a bottom plate 10. The bottom plate 10 is circularly arranged. The bottom plate 10 is clamped at the top end of the transfer pipe 9.

[0032] In this embodiment, through the bottom plate 10 and the annular mesh cover 11 provided, a collection container is formed, enabling the water flow and garbage in the transfer pipe 9 to be conveyed upward through the submersible pump provided, and at the same time, the garbage is sent into the annular mesh cover 11, facilitating the storage of the garbage. Therefore, when in use, the garbage collection capacity is increased, and it is ensured that the garbage will not block the entrance of the hydraulic generator.

[0033] Refer toFigures 1-3 On both sides of the top entrance of the bottom plate 10, baffles 13 are installed. Between the bottom sides of the baffles 13, a positioning shaft 14 is symmetrically rotatably installed. The positioning shaft 14 is connected to the baffle 13 through a torsion spring 16. At the top of the arc surface side of the positioning shaft 14, a closing plate 15 is fixedly installed, and the top sides of the two closing plates 15 are in mutual contact.

[0034] When in use, when the water flow is pumped upward by the submersible pump, it will push the closing plate 15, so that the closing plate 15 rotates through the arranged positioning shaft 14, thereby achieving the opening effect. At the same time, the garbage will be conveyed into the annular mesh cover 11. When not in use, the annular mesh plate is closed through the arranged torsion spring 16, preventing the garbage from flowing back, which increases the practicability.

[0035] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
