However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-Figure 2 As shown, the utility model provides an integrated prefabricated pump station that can effectively prevent river pollution, including: a pump station cylinder 19, the inner bottom of the pump station cylinder 19 is fixedly connected to a self-coupling base 2, the top of the self-coupling base 2 is fixedly connected to a drain pump 1 and a sewage interception pump 20, the output ends of the drain pump 1 and the sewage interception pump 20 are fixedly connected to a pressure pipe 5, the bottom of the pump station cylinder 19 is fixedly connected to an electrical control cabinet 10, the outer surface of the electrical control cabinet 10 is provided with a rain gauge 21, the inner wall of the pump station cylinder 19 is fixedly connected to a liquid level sensor 4, a water quality detector 22 is installed inside the pump station cylinder 19, the outer surfaces of the drain pump 1 and the sewage interception pump 20 are installed with water pump guide rails 3, and the two The top of each pressure pipe 5 is fixed through the inner wall of the pump station cylinder 19 and extends to the outside. The outer surfaces of the two pressure pipes 5 are installed with the first flexible joint 6, the check valve 7, the second flexible joint 8 and the gate valve 9 in sequence from front to back. The top of the pump station cylinder 19 is fixedly penetrated by a ventilation pipe 11. The outer surface of the pump station cylinder 19 is fixedly connected to the water inlet pipe 17. The right surface of the water inlet pipe 17 is fixedly connected to the crushing grid 16. The outer surface of the crushing grid 16 is provided with a grid guide rail 14. The left surface of the water inlet pipe 17 is fixedly connected to the third flexible joint 18. The sewage interception pump 20 and the drain pump 1, the liquid level sensor 4, the rain gauge 21 and the water quality detector 22 are all connected to the electric control cabinet.

[0021] The effect achieved by the entire embodiment 1 is that the upper pressure pipe 5 of the sewage interception pump 20 is connected to the external sewage pipe network, and the pressure pipe 5 of the drain pump 1 is connected to the external river. On sunny days or rainy days, the external rainwater enters the pump station cylinder 19 through the water inlet pipe 17, and then enters the pump station cylinder 19 after being processed by the crushing grid 16, so that the water quality is tested by the water quality detector 22 at the bottom. When the water quality exceeds the standard, the electrical control cabinet 10 will receive the signal and process it, control the sewage interception pump 20 to start, and extract the water inside the pump station cylinder 19 through the pressure pipe 5 and transport it to the external sewage pipe network. Under the action of the check valve 7 and the gate valve 9, the direction and flow of the water flow can be controlled, and with the assistance of multiple flexible joints, Reduce the stress and displacement of the pressure pipe 5 due to thermal expansion and contraction, vibration or foundation settlement, thereby protecting the stable operation of the pressure pipe 5. When the external rain gauge 21 detects heavy rain around and the water quality detector 22 detects that the water quality meets the standard, the electrical control cabinet 10 will stop the sewage interception pump 20 and start the drain pump 1 to discharge the rainwater in the pump station cylinder 19 into the river through the corresponding pressure pipe 5. At the same time, when the internal liquid level sensor 4 exceeds the set threshold, the sewage interception pump 20 and the drain pump 1 will work at the same time to increase the discharge of rainwater.

[0022] Example 2, as Figure 1-Figure 2 As shown, a manhole cover 13 is provided on the top of the pump station cylinder 19, and a safety grille 12 is provided at the bottom of the two manhole covers 13 on the top of the pump station cylinder 19. A water pump guide rail 3 is fixedly connected to the inner top of the pump station cylinder 19, and the water pump guide rail 3 is matched with the drain pump 1 and the sewage interception pump 20. The bottom of the pump station cylinder 19 is stepped, and a ladder 15 is provided on the inner surface of the pump station cylinder 19.

[0023] The effect achieved by the entire embodiment 2 is that by opening the manhole cover 13 and climbing the ladder 15, one can enter the pump station cylinder 19 to inspect and repair the interior, and the safety grille 12 is used to prevent people or objects from accidentally falling into the pump station cylinder 19. At the same time, with the assistance of the autocoupler base 2 and the water pump guide rail 3, the maintenance of the drain pump 1 and the sewage interception pump 20 is made more convenient, and under the action of the ventilation pipe 11 and the external axial flow fan, it is used to maintain air circulation inside the pump station cylinder 19.

[0024] Working principle: On sunny days or rainy days, external rainwater enters the pump station cylinder 19 through the water inlet pipe 17, and then enters the pump station cylinder 19 after being processed by the crushing grid 16, so that the water quality is tested by the water quality detector 22 at the bottom. When the water quality exceeds the standard, the electrical control cabinet 10 will receive the signal and process it, control the sewage interception pump 20 to start, and extract the water inside the pump station cylinder 19 through the pressure pipe 5 and transport it to the external sewage pipe network. Under the action of the check valve 7 and the gate valve 9, the direction and flow of the water flow can be controlled, and with the assistance of multiple flexible joints, the stress and displacement of the pressure pipe 5 caused by thermal expansion and contraction, vibration or foundation settlement are reduced, thereby protecting the stable operation of the pressure pipe 5. When the external rain gauge 21 detects heavy rain around and the water quality detector 22 detects the water quality, When the standard is met, the electrical control cabinet 10 will stop the sewage interception pump 20 and start the drain pump 1 to discharge the rainwater in the pump station cylinder 19 into the river through the corresponding pressure pipe 5. At the same time, when the internal liquid level sensor 4 exceeds the set threshold, the sewage interception pump 20 and the drain pump 1 will work at the same time to increase the discharge of rainwater. The sewage interception pump 20, the drain pump 1, the rain gauge 21 and the water quality detector 22 can be used to divert the mixed rainwater and sewage pipeline. When maintenance is required inside the pump station cylinder 19, the manhole cover 13 can be opened and the ladder 15 can be used to enter the pump station cylinder 19 for internal inspection and maintenance. The safety grille 12 is used to prevent people or objects from accidentally falling into the pump station cylinder 19. At the same time, with the assistance of the autocoupling base 2 and the water pump guide rail 3, the drain pump 1 and the sewage interception pump 20 are repaired more conveniently.
