AI Technical Summary
The existing submersible pumps suffer from the problem that the motor cannot be adequately cooled when the water level is lower than the design operating level, leading to overheating and burnout.
A vertical shaft integrated non-burning pump station was designed, in which the submersible pump is enclosed in a cooling vertical cylinder. The bottom of the cooling vertical cylinder is equipped with a sealing flange plate, and the area outside the water inlet is sealed. Water is drawn into the cooling vertical cylinder through the water inlet and discharged, ensuring that the motor is always submerged in water. The motor is cooled by the water pressure increase in the cooling vertical cylinder and the discharged water flow.
It effectively prevents the motor from overheating and burning out, ensuring that the motor can still work normally in river environments with low water levels, and is suitable for river environments with low water levels.

Abstract
Description
Technical Field
[0001] This utility model relates to a vertical shaft integrated non-burning pump station, belonging to the field of submersible pump technology. Background Technology
[0002] A submersible pump is a type of pump used to extract groundwater, also known as a submersible electric pump. It mainly consists of two parts: a water pump and a motor. The motor is coaxially connected to the water pump and sealed within a pressure-resistant, waterproof casing. The water pump is located below the motor, and the entire submersible pump operates submerged in water. The working principle of a submersible pump is that the pump and motor are integrated. The motor's rotation drives the impeller, drawing water in through the inlet, pressurizing it through internal flow channels, and then discharging it through the outlet. The submersible pump relies on water cooling to ensure the motor's normal operation. If the water level is lower than the submersible pump's design operating level, such as in small ditches or rivers, the water will not adequately cover the motor, resulting in insufficient cooling. This can cause the motor temperature to rise rapidly, potentially burning out the motor. Utility Model Content
[0003] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a vertical shaft integrated non-burning pump station that can ensure heat dissipation and prevent pump burnout, which can be applied to rivers with low water levels.
[0004] The vertical shaft integrated non-fired pump station of this utility model includes a submersible pump, which is enclosed in a cooling vertical cylinder. The bottom of the cooling vertical cylinder is provided with an annular sealing flange plate. The water inlet of the submersible pump is connected to the sealing flange plate, and the sealing flange plate seals the area outside the water inlet. The cooling vertical cylinder is connected to a water outlet pipe.
[0005] During operation, the submersible pump draws water in through the inlet and discharges it into the cooling cylinder through the outlet. The water pressure in the cooling cylinder increases, and the water inside the cooling cylinder is then discharged through the outlet pipe. The submersible pump motor is located inside the cooling cylinder and is always submerged in water, so it will not burn out even if the river water level is lower than the pump motor.
[0006] The cooling vertical cylinder is fixed to the bottom of the riverbed.
[0007] Preferably, a debris-blocking cylinder is provided between the cooling vertical cylinder and the bottom of the riverbed to prevent silt, debris and other substances from entering the pump body.
[0008] Preferably, the water outlet pipe is equipped with an electric flow control valve.
[0009] Preferably, a water meter is installed on the water outlet pipe.
[0010] Preferably, the water outlet pipe is equipped with a remote pressure gauge.
[0011] The advantages of this utility model compared with the prior art are:
[0012] The vertical shaft integrated non-burning pumping station described in this utility model encloses the submersible pump inside a cooling vertical cylinder. A sealing flange at the bottom of the cooling vertical cylinder seals off the area outside the water inlet. When the submersible pump is operating, water is drawn in and discharged into the cooling vertical cylinder through the outlet, ensuring the submersible pump motor is always submerged. This effectively solves the problem of insufficient motor cooling when the water level is below the submersible pump's design operating level, thus preventing motor overheating and burnout. Due to the cooling vertical cylinder design, even in low-water-level river conditions, the submersible pump motor is adequately cooled, making this vertical shaft integrated non-burning pumping station particularly suitable for low-water-level river environments.

[0015] The present invention will be further described below with reference to specific embodiments.
[0016] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.
[0017] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.
[0018] like Figure 1 As shown, this embodiment is achieved through the following technical solution: it includes a submersible pump 1, which is enclosed in a cooling vertical cylinder 2. An annular sealing flange plate 3 is welded to the bottom of the cooling vertical cylinder 2. The water inlet 5 of the submersible pump 1 is welded together with the sealing flange plate 3, so that the sealing flange plate 3 seals the area outside the water inlet 5.
[0019] The top of the cooling vertical cylinder 2 is connected to the water outlet pipe 8 via an elbow 7. The water outlet pipe 8 is equipped with an electric flow control valve 9, a water meter 10, and a remote pressure gauge 11. The pump station is equipped with a control cabinet 12.
[0020] In this embodiment, the bottom of the cooling vertical cylinder 2 is connected to the debris-blocking cylinder 4 via a flange, and the debris-blocking cylinder 4 is fixed to the bottom of the riverbed.
[0021] During operation, the submersible pump 1 draws water in through the inlet 5 and discharges it into the cooling cylinder 2 through the outlet 6. The water pressure inside the cooling cylinder 2 increases, and the water is then discharged through the outlet pipe 8. The submersible pump motor is located inside the cooling cylinder 2 and is always submerged in water, preventing it from burning out even if the river water level is lower than the motor. Therefore, it can be used in low-lying ditches and similar waterways.
[0022] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
