Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering pump station structure. Background Technology

[0002] In water conservancy pumping stations, sewage usually contains various impurities and garbage, such as plastic bags, branches, stones, etc. If these impurities directly enter the pumping station, they will not only affect the working efficiency of the pump, but may also damage the equipment or block the pipes, thus affecting the normal operation of the entire pumping station.

[0003] The existing pump station structure does not have a special device to crush or intercept large debris, which makes it easy for debris to enter the pump body, causing blockage or damage. Even with a simple filter screen, the filtered impurities are not easy to clean, and blockage will still occur after a period of use. Cleaning work is complicated and time-consuming, requiring frequent shutdowns for maintenance, which increases operating costs and time costs.

[0004] Therefore, a new type of water conservancy engineering pump station structure is needed. Utility Model Content

[0005] The technical problem this invention aims to solve is that the presence of impurities makes the pump body prone to clogging, affecting its use and making it difficult to clean. The invention provides a novel structure for water conservancy engineering pump stations.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pumping station structure for water conservancy projects, including a pumping station base, a cylinder, a reinforcing cylinder cover, a submersible sewage pump, pipelines, an inlet pipe and an outlet pipe. The cylinder is fixedly installed on the top surface of the pumping station base, and the top is sealed by the reinforcing cylinder cover. Water enters the cylinder through the inlet pipe on one side of the cylinder, is drawn by the submersible sewage pump fixed on the pumping station base, and is transferred to the outlet pipe on the other side of the cylinder for release. It also includes a pulverizing screen, a filter screen cylinder and a cleaning mechanism.

[0007] After the shredder is fixed inside the cylinder by the support rod, it is connected to one end of the water inlet pipe to shred debris and garbage in the sewage.

[0008] A safety maintenance platform is horizontally placed inside the cylinder between the inlet and outlet pipes. A filter screen is fixed on the safety maintenance platform. A connecting pipe connected to the pulverizing grid is provided on one side of the filter screen. After impurities are left inside the filter screen, they are cleaned regularly by a cleaning mechanism.

[0009] As an improvement, multiple pipelines are installed, and each pipeline is equipped with a check valve. The check valves are located above the safety maintenance platform to improve water delivery efficiency and prevent water backflow.

[0010] As an improvement, a liquid level sensor is installed on the bottom of the safety maintenance platform. The liquid level sensor is connected in conjunction with the submersible pump to prevent water from overflowing onto the safety maintenance platform and affecting the use of electrical components.

[0011] As an improvement, the cleaning mechanism includes a screw conveyor and a motor;

[0012] The filter cylinder is a cylindrical tube. The motor is mounted on the top surface of the safety maintenance platform via a support frame. The shaft is connected to a spiral conveyor rod located inside the filter cylinder. The filter cylinder is equipped with a drain port located above the safety maintenance platform. Impurities are continuously conveyed upwards by the spiral conveyor rod and released through the drain port, achieving efficient cleaning of impurities inside the filter cylinder and reducing the risk of clogging.

[0013] As an improvement, a collection frame is also included. After being placed on the safety maintenance platform, the collection frame is detachably connected to the filter cylinder and communicates with the drain outlet to collect the cleaned impurities.

[0014] As an improvement, the outer wall of the filter cylinder is provided with mounting slots, and a pair of mounting slots are mirrored. The collection frame is an arc-shaped frame that fits the filter cylinder. The inner wall of the collection frame is provided with a pair of mounting rods that fit the mounting slots. After the mounting rods are pushed into the mounting slots, the collection frame is close to the outer wall of the filter cylinder, and the drain outlet is close to the top of the collection frame, which facilitates maintenance.

[0015] As an improvement, the shredder uses a set of parallel toothed or mesh structures (i.e., bars) to intercept larger solids in wastewater. When wastewater flows through the shredder, the solids intercepted by the bars are further processed by moving blades or cutting devices on a rotating shaft. These blades or cutting devices are driven by a motor and rotate at high speed.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. By installing a shredder, large debris entering the pumping station can be effectively shredded, preventing damage to the submersible pump and pipelines;

[0018] 2. It uses a filter cylinder to filter fine particles and is equipped with an automated cleaning mechanism that can periodically and automatically clean the impurities accumulated inside the filter cylinder, making maintenance convenient and reducing the risk of clogging.

The water is then transferred to the outlet pipe 7 on the other side of the cylinder 2 through the pipeline 5 for release. There are multiple pipelines 5, and each pipeline 5 is equipped with a check valve 12. The check valve 12 is located above the safety maintenance platform 10 to improve water delivery efficiency and prevent water backflow.

[0029] With the above structure, water enters the cylinder 2 through the inlet pipe 6, is drawn by the submersible pump 4 and transmitted to the outlet pipe 7 through the pipeline 5 for use, and the check valve 12 prevents water backflow.

[0030] Example 2

[0031] Based on Example 1, combined with Appendix Figure 2 and 4 As shown in -5, it also includes a crushing screen 8; after the crushing screen 8 is fixed inside the cylinder 2 by a support rod, it is connected to one end of the water inlet pipe 6 to crush debris and garbage in the sewage.

[0032] It also includes a filter cylinder 9. Inside the cylinder 2, a safety maintenance platform 10 is horizontally placed between the inlet pipe 6 and the outlet pipe 7. A liquid level sensor 13 is installed on the bottom of the safety maintenance platform 10.

[0037] In the specific implementation of this utility model, the inlet pipe 6 is opened to allow sewage to flow into the cylinder 2. After passing through the crushing grid 8, the sewage undergoes preliminary crushing treatment. The crushed sewage continues to flow to the filter screen cylinder 9, where the remaining fine particles are further removed.
