Description

Technical Field

[0001] This utility model relates to the technical field of integrated prefabricated pumping stations, and in particular to an integrated prefabricated pumping station with remote water-stopping and maintenance functions. Background Technology

[0002] Integrated prefabricated pumping stations are booster pumping equipment for sewage, rainwater, drinking water, and wastewater. They are manufactured and assembled in a factory and then transported to the site for installation. They consist of a cylinder system, pipe and valve system, manual bar screen, control system, and other components to meet the requirements of boosting and lifting drainage. Integrated prefabricated pumping stations are characterized by small footprint, extremely short construction period, and extremely simple installation. Currently, they are becoming a new trend in pumping station construction in the domestic municipal water conservancy industry.

[0003] For example, in the utility model patent application number CN202322228098.3, the integrated prefabricated pump station is a representative of a class of prior art. Its main structure includes reinforcing ribs, manholes, air ducts, filter caps, filter boxes, fans, and support rods. The function of the integrated prefabricated pump station is realized through the cooperation of the reinforcing ribs, manholes, air ducts, filter caps, filter boxes, fans, and support rods.

[0004] In actual use, existing integrated prefabricated pumping stations require regular maintenance by staff. During maintenance, sewage continues to flow into the pumping station through the inlet pipe, resulting in sewage remaining at the bottom of the pumping station's cylinder, hindering maintenance. Furthermore, when sewage enters the pumping station through the pipe, large suspended solids and floating debris are intercepted by a manual screen. However, after a certain period, the screen's drainage holes become clogged. When operators clean the screen through the maintenance port, the sewage, no longer blocked by the screen, still allows large suspended solids and floating debris to flow into the cylinder. When the sewage is subsequently pumped out, the presence of these large suspended solids and floating debris can cause blockages, affecting the pump's normal operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated prefabricated pumping station with remote water-stopping maintenance function. By installing a knife gate valve at the inlet of the prefabricated pumping station, operators can remotely or manually control the opening and closing of the gate valve to effectively block subsequent sewage from entering the cylinder during the maintenance of the prefabricated pumping station, thereby reducing operation and maintenance costs and improving the practicality of the equipment.

[0006] This utility model discloses an integrated prefabricated pumping station with remote water-stopping and maintenance functions, comprising a pumping station system; it also includes a lifting and conveying system, a bar screen system, a pipe and valve system, and a control system. The pumping station system is entirely constructed of high-strength fiberglass. A maintenance cover is provided on the top of the pumping station; a fixed steel ladder is located beneath the maintenance cover; an automatic coupling device is provided at the bottom of the prefabricated pumping station; the automatic coupling device is connected to a sewage and wastewater submersible pump and a pressure boosting pipeline; the pipe and valve system includes check valves, gate valves, and knife gate valves; the control system includes a liquid level detection system, a video monitoring system, and a remote control system. After the pumping station is prefabricated in the factory, it can be directly hoisted and installed on-site for immediate use. Furthermore, by adding a knife gate valve to the inlet of the integrated prefabricated pumping station, operators can remotely or manually control the knife gate valve to close during maintenance, effectively intercepting large suspended and floating solids in the sewage, reducing operating and maintenance costs, and improving the practicality of the equipment.

[0007] Preferably, in the cylindrical system, the top of the pump station is equipped with an aluminum alloy cover plate, and a fixed steel ladder is installed below the aluminum alloy cover plate. The pump station inlet is equipped with a knife gate valve, and a manual screen is installed behind the knife gate valve. The pump station is equipped with a submersible electric pump for sewage and waste. When using the pump station, after the pump station is installed in the designated position, the operator controls the knife gate valve through a hand-operated electric hoist during daily use. When the inlet knife gate valve is opened, sewage flows into the prefabricated pump station cylinder through the inlet pipe, improving the practicality of the equipment.

[0008] Preferably, the system also includes a lifting and conveying system for lifting and conveying sewage and waste. Sewage flows into the prefabricated pumping station cylinder. When the liquid level in the cylinder reaches the pump start level, the liquid level sensor outputs a pump start signal to the electrical cabinet. The electrical cabinet controls the sewage and waste submersible electric pump to start, thereby starting the lifting and conveying process and improving the practicality of the equipment.

[0009] Preferably, the pump station is equipped with an inlet pipe, and the inlet pipe is equipped with a manual screen; the manual screen intercepts large suspended solids and floating objects in the sewage, effectively preventing large suspended solids and floating objects from entering the prefabricated pump station cylinder and causing blockage of the sewage submersible pump, thus improving the practicality of the equipment.

[0010] Preferably, the inlet pipe is equipped with a knife gate valve; the knife gate valve has low resistance to sewage fluid, the sealing surface is less affected by the scouring and erosion of the medium, is unrestricted, does not cause flow disturbance or pressure reduction, and is easier to open and close. During the maintenance of the prefabricated pumping station, the knife gate valve blocks subsequent sewage from entering the prefabricated pumping station, which facilitates maintenance and improves the practicality of the equipment.

[0011] Preferably, the pump station is equipped with a guide rod and rail assembly; the guide rod and rail assembly is used for maintenance of the submersible pump, allowing operators to lift the submersible pump from the bottom of the pump station to the top for repair, thus improving the practicality of the equipment.

[0012] Preferably, the valve system consists of pressure pipelines, check valves, gate valves, and flexible connections; when the valve system is used for sewage lifting and conveying, it prevents sewage and waste backflow and improves the practicality of the equipment.

[0013] Preferably, the control system includes a video monitoring system and a remote operating system; when the liquid level reaches the pump start-up level again, the control system automatically feeds back a signal to start and stop the sewage and waste submersible electric pump, thereby improving the practicality of the equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: After the pump station is prefabricated in the factory, it can be directly hoisted and installed on site and used immediately. Furthermore, by adding a knife gate valve to the inlet of the integrated prefabricated pump station, the operator can remotely or manually control the knife gate valve to close during the maintenance of the prefabricated pump station, effectively intercepting large suspended solids and floating objects in the sewage, reducing operation and maintenance costs, and improving the practicality of the equipment.

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] An integrated prefabricated pumping station with remote water-stopping and maintenance functions includes a pumping station system; it also includes a lifting and conveying system, a bar screen system, a pipe and valve system 12, and a control system. The pumping station system is entirely made of high-strength fiberglass. A maintenance cover 9 is provided on the top of the pumping station; a fixed steel ladder 10 is provided under the maintenance cover 9; an automatic coupling device is provided at the bottom of the prefabricated pumping station; the automatic coupling device is connected to a sewage and waste submersible electric pump 11 and a pressure lifting pipeline; the pipe and valve system 12 includes check valves, gate valves, and knife gate valves 6; the control system includes a liquid level detection system, a video monitoring system 4, and a remote control system.

[0022] After the prefabrication of pump station 1 is completed in the factory, it can be delivered to the site for direct hoisting and installation and then put into use. In addition, by adding knife gate valve 6 to the inlet of the integrated prefabricated pump station, the operator can remotely or manually control the knife gate valve 6 to close during the maintenance of the prefabricated pump station, effectively intercepting large suspended solids and floating objects in the sewage, reducing operation and maintenance costs and improving the practicality of the equipment.

[0023] The system includes a cylindrical body, with an aluminum alloy cover plate on top of the pump station 1, a fixed steel ladder 10 below the cover plate, a gate valve 6 at the inlet of the pump station 1, a manual screen 7 behind the gate valve 6, and a submersible electric pump 11 for sewage and waste. It also includes a lifting and conveying system for lifting and conveying sewage and waste. An inlet pipe 2 is installed on the pump station 1, with a manual screen 7 installed on it. The inlet pipe 2 is equipped with a gate valve 6. A guide rod and guide rail assembly is installed inside the pump station 1. The valve system 12 consists of pressure pipelines, check valves, gate valves, and flexible connections. The control system includes a 4 and a remote operating system.

[0024] When using pump station 1, after installing it in the designated location, the operator controls the knife gate valve 6 via the hand-operated electric hoist 8 during daily use. The inlet knife gate valve 6 opens, allowing sewage to flow into the prefabricated pump station cylinder through 2. When the liquid level inside the cylinder reaches the pump start-up level, the level sensor outputs a pump start-up signal to the electrical cabinet 5. The electrical cabinet 5 then controls the sewage submersible pump 11 to start, initiating the lifting and conveying process. The manual screen 7 intercepts large suspended and floating objects in the sewage, effectively preventing them from entering the prefabricated pump station cylinder and causing damage to the sewage submersible pump 1. 1. Blockage: The knife gate valve 6 has low resistance to sewage fluid, and the sealing surface is less affected by the scouring and erosion of the medium. It is unrestricted, does not cause flow disturbance or pressure reduction, and is easier to open and close. During the maintenance of the prefabricated pumping station, the knife gate valve 6 blocks subsequent sewage from entering the prefabricated pumping station, facilitating maintenance. When the guide rod and rail assembly is used for the maintenance of the submersible pump, the operator can use the guide rod and rail to lift the submersible pump from the bottom of 1 to the top of the pumping station for maintenance. When the pipe valve system 12 is used for sewage lifting and transportation, it prevents sewage and sludge backflow. When the liquid level reaches the pump start-up level again, its control system automatically feeds back a signal to realize the start and stop of the sewage and sludge submersible pump 11, improving the practicality of the equipment.

[0025] like Figures 1 to 3 As shown, this utility model discloses an integrated prefabricated pumping station with remote water-stopping and maintenance functions. During operation, after the operator installs pumping station 1 in the designated location, the gate valve 6 opens during normal use, allowing sewage to flow into the prefabricated pumping station cylinder through valve 2. Large suspended and floating objects are intercepted by valve 7. When the liquid level in the cylinder reaches the pump start level, the level sensor outputs a pump start signal to the electrical cabinet 5. The electrical cabinet 5 then controls the sewage submersible pump 11 to start, and the sewage submersible pump 11 begins lifting and conveying. When the liquid level reaches the pump stop level, the level sensor outputs a stop signal. The pump sends a signal to the electrical cabinet 5, which controls the sewage submersible pump 11 to stop, thus halting its operation. When the liquid level reaches the pump start-up level again, the control system automatically sends a signal to start and stop the sewage submersible pump 11. After a period of use, if the water passage of the manual screen 7 becomes clogged with large suspended and floating objects, the operator needs to clean it through the inspection port. Specifically, the operator closes the knife gate valve 6 remotely or manually to prevent sewage from continuing to flow into the cylinder, effectively preventing large suspended and floating objects from entering the cylinder and causing blockage of the sewage submersible pump 11, thus reducing the risk of equipment damage.

[0026] The pump station 1, video monitoring system 4, electrical cabinet 5, manual and electric dual-purpose gate opener 8, and sewage and waste submersible electric pump 11 of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0027] The main function achieved by this utility model is: by installing a knife gate valve 6 at the inlet of the prefabricated pumping station, the operator can remotely or manually control the opening and closing of the gate valve 6, so as to effectively block the subsequent sewage from entering the cylinder during the maintenance of the prefabricated pumping station, reduce the operation and maintenance cost, and improve the practicality of the equipment.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
