Description

TECHNICAL FIELD

[0001] The utility model relates to a lifting tower, in particular to a seawater lifting tower. BACKGROUND

[0002] The seawater lifting tower is a relatively important work for offshore operation, which is mainly used for introducing seawater in the sea into a workbench for operation. During the operation of a ship, seawater is an important cooling medium. After the seawater acts on the ship, the seawater lifting tower lifts the seawater to a deck seawater main pipe, thereby providing seawater for the ship leaving the sea surface.

[0003] For example, a seawater lifting tower with simple structure disclosed in Chinese patent publication No. CN211596906U includes a tower, a base and a water intake mechanism. A hollow groove is formed in the middle inner side of the tower, and protective rods are installed on the front of the tower. The base is fixed to the lower side of the tower, and a lifting mechanism is installed on the outer side of the tower. The water intake mechanism is arranged above the lifting mechanism. The seawater lifting tower with simple structure is provided with protective rods arranged in a cross shape to facilitate protection of both sides of the tower. The protective rods and the tower are connected by welding, making the connection more secure. The structure of the tower and the protective rods is relatively simple.

[0004] However, in the above-mentioned scheme, the lifting tower is inconvenient for cleaning the filter screen at the bottom of the water suction end during use, which causes garbage in seawater to easily adhere to the filter screen and affect the extraction of seawater, and the convenience is not high. SUMMARY

[0005] The technical problem to be solved by the utility model is to provide a seawater lifting tower which can conveniently clean the filter screen at the bottom of the water suction end.

[0006] To solve the above-mentioned technical problem, the utility model adopts the following technical scheme:

[0007] A seawater lifting tower includes a tower body, two groups of submersible pumps are installed in the tower body, the water suction end of each group of submersible pumps is connected with a water suction pipe, and the water outlet end is connected with a drainage pipe with a second electromagnetic valve. The drainage pipe of each group of submersible pumps is connected with a water guide pipe at one end, a first electromagnetic valve is installed on the water guide pipe, and the other end of the water guide pipe is communicated with the sidewall of the water suction pipe of the other group of submersible pumps.

[0008] The water guide pipe extends into the water suction pipe and is opposite to the filter screen in the water suction head at the bottom end of the water suction pipe.

[0009] The water suction pipe is arranged in a Z shape.

[0010] The bottom opening of the water suction head is larger than the top opening.

[0011] The top plate is fixed with a U-shaped fixed plate at the lower end, a motor is installed on the top plate, the motor output shaft is freely through the top plate and is connected with a threaded rod, the other end of the threaded rod is rotatably installed at the bottom of the U-shaped fixed plate; the mounting plate is threadedly connected with the threaded rod and is attached to the side walls of the U-shaped fixed plate on both sides; two groups of submersible pumps are installed on the mounting plate.

[0012] The tower body is made of stainless steel material, and a salt-resistant and corrosion-resistant coating is sprayed on the surface of the tower body.

[0013] The flow rate sensor is installed in the drain pipe.

[0014] The seawater lifting tower has the following technical effects:

[0015] 1) By arranging two sets of water pumping devices and installing water guide pipes on the water suction pipe and the drain pipe, the filter screen in the water suction head can be cleaned, so that the garbage in the seawater is prevented from adhering to the surface of the filter screen and affecting the pumping of the seawater, and the operation is simple, convenient and fast.

[0016] 2) Since the platform ship can be lifted, the height of the platform from the water surface is different in different construction periods, so the height needs to be adjusted to pump water. The screw rod mechanism can be used for lifting and adjusting the water pumping device, so that the height of the submersible pump can be adjusted, thereby facilitating the pumping of seawater.

[0026] The height adjusting structure includes a motor 12, the motor 12 is fixedly connected on the top side wall of the top plate 11, the output shaft of the motor 12 penetrates the side wall of the top plate 11 and is in rotary connection with the top plate 11, one end of the output shaft of the motor 12 is fixedly connected with a threaded rod 9, and the threaded rod 9 is in rotary connection with the top plate 11. The bottom of the top plate 11 is fixedly connected with a U-shaped fixed plate 10, the bottom of the threaded rod 9 is rotatably connected to the inner bottom side wall of the U-shaped fixed plate 10, the outer circle side wall of the threaded rod 9 is threadedly connected with a mounting plate 8, the two side walls of the mounting plate 8 are in abutment with the two inner side walls of the U-shaped fixed plate 10, and the two submersible pumps 7 are fixedly connected to the side wall of the mounting plate 8.

[0027] By starting the motor 12, the output shaft of the motor 12 drives the threaded rod 9 to rotate, and the threaded rod 9 can drive the mounting plate 8 to move up and down when rotating, so as to adjust the height of the two submersible pumps 7, thereby facilitating the extraction of seawater at different depths.

[0028] The motor 12 is provided in a waterproof type, so as to prevent the motor 12 from being affected in use due to rust and electric leakage.

[0029] The foreign matter cleaning structure includes two water guide pipes 3, one end of each water guide pipe 3 is fixedly connected to the side wall of the corresponding drain pipe 13 and is in communication with the drain pipe 13, and the side wall of each water guide pipe 3 is provided with a first electromagnetic valve 2. One end of the left water guide pipe 3 is fixedly connected to the top side wall of the right water suction pipe 6, and one end of the right water guide pipe 3 is fixedly connected to the top side wall of the left water suction pipe 6. The two water guide pipes 3 are in communication with the corresponding water suction pipe 6, the outlets of the two water guide pipes 3 are located directly above the two filter screens 5 respectively, each of the two drain pipes 13 is provided with a flow rate sensor 15, and the upper end side wall of each of the two drain pipes 13 is provided with a second electromagnetic valve 14.

[0030] When the flow rate in the left drain pipe 13 decreases, the left submersible pump 7 is closed, the second electromagnetic valve 14 of the right drain pipe 13 is closed, and the first electromagnetic valve 2 of the left guide pipe 3 is opened, so that the seawater in the right drain pipe 13 flows into the left suction pipe 6 through the right guide pipe 3, thereby washing the filter screen 5 at the bottom of the left suction head 4, cleaning the garbage at the bottom of the filter screen 5, and preventing the garbage from affecting the pumping of seawater by the submersible pump 7.

[0033] Working principle and process:

[0034] Through the two submersible pumps 7, the seawater can be pumped out through the suction pipe 6 and discharged through the two drain pipes 13 by starting the submersible pump 7, thereby utilizing the seawater.

The flow rate sensor 15 can detect the flow rate of seawater in the drain pipe 13 when the submersible pump 7 is started.

[0036] When the flow rate in the left drain pipe 13 decreases, the left submersible pump 7 is closed, the right second electromagnetic valve 14 is closed, and the first electromagnetic valve 2 of the right guide pipe 3 is opened, so that the seawater in the right drain pipe 13 flows into the left suction pipe 6 through the right guide pipe 3, thereby washing the filter screen 5 at the bottom of the left suction head 4, cleaning the garbage at the bottom of the filter screen 5, and preventing the garbage from affecting the pumping of seawater by the submersible pump 7. After cleaning, the right second electromagnetic valve 14 is opened and the right first electromagnetic valve 2 is closed.

[0037] When the flow rate in the right side drain pipe 13 decreases, the right side submersible pump 7 is closed, the left side second electromagnetic valve 14 is closed and the left side first electromagnetic valve 2 of the side wall of the water guide pipe 3 is opened, so that the filter screen 5 at the bottom of the right side water suction pipe 6 is washed.
