Description

Technical Field

[0001] The utility model relates to the field of sewage pump station simulation devices, in particular to a pump station simulation training platform. Background Art

[0002] Sewage pumping stations are an important part of the sewage system. During the daily operation of the pumping station, a large amount of garbage enters the pumping station along with sewage through the sewage pipe network, resulting in serious garbage blockage in the pumping station, which seriously damages the grilles and water pumps in the pumping station and other common operating failures. The rainwater and sewage pumping station plays an important role in urban flood control and drainage, and sewage transportation. However, there is a lack of professional and technical personnel in the society for the operation and maintenance of pumping stations. After further investigation, we can find that it is mainly caused by the following three reasons:

[0003] 1. Rainwater and sewage pumping stations are municipal facilities and are generally managed by relevant municipal units. There are not many such units and they belong to a niche industry, so there is a shortage of corresponding technical personnel in society.

[0004] 2. The construction cost of rainwater and sewage pumping stations is relatively high, and there is no professional practical training platform on the market, so there are few opportunities for such professional and technical personnel to learn and practice.

[0005] 3. The operation and maintenance of the rainwater and sewage pumping station involves professional equipment such as water pumps, high and low voltage power distribution systems, screen machines, valves, etc., which are highly comprehensive and professional.

[0006] In the training process of pump station maintenance personnel, new employees often have to wait until a pump station failure occurs before they can have the opportunity for practical training. Moreover, since the probability of failures varies, it takes a very long time for new employees to fully understand the types of pump station failures outside of books and actually perform maintenance.

[0007] Therefore, if a training device that simulates common faults in pump station operation can be designed, the pump station operation can be carried out, which basically covers all pump station operation operations and conventional pump station facility maintenance operations. By designing fault simulation, new employees can understand relevant knowledge firsthand during the training process, realize hands-on operation, and conduct targeted simulation assessments. Utility Model Content

[0008] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a pump station simulation training platform.

[0009] The technical solution of the utility model is as follows: a pump station simulation training platform, including a water collecting tank, a regulating water tank, a water outlet pipe, a water inlet pipe, a submersible pump, an electric gate valve and a PLC controller. The water collecting tank is provided with a partition and a grille for dividing the water collecting tank into an inlet side and an outlet side. The submersible pump is arranged on the outlet side and connected with one end of the outlet pipe, and the other end of the outlet pipe is connected with the regulating water tank. Both ends of the inlet pipe are respectively connected with the inlet side and the regulating water tank. The inlet pipe is provided with an electric gate valve, and the PLC controller controls the start and stop of the submersible pump and the electric gate valve.

[0010] By adopting the above technical solution, the submersible pump and electric gate valve are controlled by the PLC controller to start and stop, so that the water in the water collecting tank and regulating water tank simulates sewage circulation. The submersible pump pumps the water on the outlet side into the outlet pipe to the regulating water tank. The electric gate valve is started and stopped to make the water in the regulating water tank flow back to the inlet side of the water collecting tank, and the water on the inlet side enters the outlet side through the grille, completing the sewage circulation and continuously entering the pump station.

[0011] The water volume in the regulating water tank is adjusted to simulate the change in the water flow rate at the collecting tank.

[0012] The trainers conduct practical training and eliminate faults based on the fault command signals that appear during the operation of the simulated pump station.

[0014] By adopting the above technical solution, the cleaning process of the pump station is simulated through the sewage pipe. The submersible pump is turned off, and the dry sewage pump and the manual gate valve are opened to discharge the simulated sewage on the outlet side. The discharged water continues to circulate back to the regulating water tank through the outlet pipe.

[0015] The utility model is further configured as follows: the outlet pipe is provided with a one-way valve and a manual gate valve for opening and closing the outlet pipe between the sewage pipe and the submersible pump; the sewage pipe is provided with a one-way valve and a manual gate valve for opening and closing the sewage pipe.

[0016] By adopting the above technical solution, the opening and closing of different pipelines are controlled between the pump station circulation and the pump station drainage maintenance.

[0017] The utility model is further configured as follows: an electromagnetic flowmeter is arranged between the water outlet pipe and the regulating water tank, and the water collecting tank and the regulating water tank are both provided with an emptying port and a manual ball valve for opening and closing the emptying port at the upper and bottom parts.

[0018] The above technical solution is adopted to simulate the statistics of water inlet and outlet flow of the pump station, and the drain port is convenient for the overall emptying, cleaning and maintenance of the water collection tank and regulating tank.

[0019] A further configuration of the utility model is that an overflow pipe is provided between the water collecting tank and the regulating water tank.

[0020] The above technical solution is adopted to prevent the water in the regulating water tank from overflowing during the simulation operation.

[0021] A further configuration of the utility model is as follows: the platform further comprises a gantry crane arranged above the water collecting tank, and a climbing ladder is arranged on the outside of the water collecting tank.

[0022] By adopting the above technical solution, a small gantry crane is set up to enable the trainees to carry out practical training on the lifting and maintenance of submersible pumps and other equipment, and a climbing ladder is set up to facilitate the trainees to enter and exit the water collecting tank for maintenance training.

[0023] Further configuration of the utility model: a liquid level meter is arranged on the water outlet side, the grille comprises a grille frame, a plurality of gate members, and an electrically controlled driving element, the grille frame is provided with a plurality of water gates connecting the water inlet side and the water outlet side, the gate members are arranged at the water gates and are mechanically connected to the electrically controlled driving element, the PLC controller is connected to the electrically controlled driving element by signal, and drives each gate member to open and close each water gate to control the flow rate.

[0024] By adopting the above technical scheme, through the use of electronically controlled driving elements such as servo motors driving gate parts to flip and open and close the sluice gates, and cylinders driving gate parts to lift and lower and open and close the sluice gates, the situation in which the pump station grille is blocked by debris carried by sewage and the flow rate on the outlet side is reduced is simulated, so that the trainees can conduct practical training under conditions closer to the actual working conditions.

[0025] Compared with the prior art, the beneficial effects of the utility model are: the pump station simulation training platform designed in this application realizes the pump station operation simulation through the setting of equipment such as water collecting tanks and regulating tanks.
