Low merits are required.

Description

floating pumping station

technical field

The utility model belongs to the field of general machinery, in particular to a pumping station for a floating boat.

Background technique

When pumping water in the existing floating boat pumping station, the water inlet pipe is generally vacuumed first with a vacuum pump, and then pumped; or a water diversion pump is used to pump water, but it needs to be filled with water and vented in advance, otherwise it will not work because it cannot absorb water.

And because the inlet pipeline of the pontoon pumping station is long, there is no air in the inlet pipe before pumping water, so the requirements for the tightness of the pipeline are relatively high, and the inlet bottom valve is required to have no leakage, otherwise cavitation will easily occur.

Therefore, not only the water cannot be supplied in time due to structural problems, and it is inconvenient to use, but also it is more prone to failure due to high system requirements.

Simultaneously, the pontoon of existing pontoon pumping station is generally the structure that adopts metal material, and its environmental adaptability is poor, often rusts because of contacting with water, especially in seawater environment, often corrodes seriously, and service life is short; And , The structure of the pontoon is complicated, and disassembly and assembly are particularly inconvenient.

Utility model content

In view of the above problems, the utility model aims to provide a floating pumping station with simple structure and convenient installation and maintenance. The floating pumping station can quickly pump water immediately after starting without vacuuming or filling in advance.

The technical scheme for solving the problem of the utility model is: a floating boat pumping station, including a floating boat supporting the whole pumping station, at least one vertical pump is installed on the floating boat, its impeller is a wet pit type, and the pumping working parts of the vertical pump are inserted into the water Next, the outlet of the vertical pump is connected with an outlet pipe, and a check valve and a shut-off valve are arranged between the outlet of the vertical pump and the outlet pipe.

The pontoon is spliced by buoys made of high molecular polyethylene material;

Moreover, a control cabinet for transmitting monitoring information is also provided on the floating boat.

The vertical pump includes an impeller, a guide vane body, a main shaft connecting the hydraulic components in series, an intermediate coupling, a suction bell, an external pipe, and a discharge elbow; the lower end of the main shaft at the suction bell is equipped with a The supporting guide bearing is connected to the main shaft through a bushing.

In order to avoid "water hammer effect", the check valve is an anti-hammer valve; the stop valve is used for convenient maintenance.

In the above technical solution, a sunken maintenance platform is provided at the position where the pump and the pipeline are arranged on the upper surface of the pontoon to facilitate maintenance.

For the convenience of maintenance, a lifting device for maintenance is provided on the pontoon.

The beneficial effects of the utility model are:

1. Since the pump for pumping water is replaced by a vertical pump, the floating pumping station can quickly pump water immediately after starting without vacuuming or filling water in advance, which saves the step of exhausting air in the traditional technology and makes the operation easier Simpler and more productive.

2. The structure of the pontoon is designed as a splicing of high molecular polyethylene buoy materials. The modular components make the disassembly and assembly of the pontoon more convenient and quick. To expand the area of the pontoon and increase the buoyancy, it only needs to be assembled on the basis of the original pontoon. In addition, the pontoon is resistant to ultraviolet radiation and corrosion, especially seawater corrosion, and has a longer service life.

3. Since there is no need to exhaust air, the requirements for the sealing of the inlet pipe of the system are not high, and the inlet bottom valve is also omitted, which reduces the cost accordingly.

4. The setting of the control cabinet can monitor the operation of the floating pumping station in real time and provide timely feedback information, which is conducive to timely resolution of faults and control of equipment status.

5. The vertical pump used in the utility model is designed with a support guide bearing to prevent the pump from shaking. When the pontoon swings, it can avoid the pump shaking and will not affect the work of the pump group.
