[0009] In a preferred solution, a plurality of float switches are provided on the main pipeline. The float switches are arranged above the corresponding first branch pipeline. The position of the float switches is higher than the height of the second branch pipeline on the corresponding first branch pipeline. The float switches are used to detect whether the first branch pipeline is still in water, and the controller thereby controls the electric valve on the first branch pipeline to close.

[0010] In a preferred solution, a pressure sensor is also provided on the first branch pipeline at the bottom. The pressure sensor is electrically connected to the controller, and the pressure sensor is used to detect whether the pipe rack is in contact with the underwater bottom.

DETAILED DESCRIPTION

[0019] Example 1 See also Figure 1-5As shown, an embodiment of the present application provides a technical solution: comprising a pipe rack 11 and an aeration nozzle 101 arranged on the pipe rack 11, the pipe rack 11 comprises a main pipe 111, a clamping rod 17 is provided above the main pipe 111, a hanging ring 12 is provided above the clamping rod 17, an air intake pipe 114 is provided on one side above the main pipe 111, a plurality of layered and detachable first branch pipes 112 are provided around the main pipe 111 below the air intake pipe 114, and a plurality of detachable second branch pipes 113 are provided on the first branch pipe 112.

[0020] The aeration nozzle 101 is set on the pipe rack 11, and each bracket has it (only a part is omitted in the figure), and the main pipeline 111 is set on the center of gravity of the whole pipe rack 11, so that the pipe rack 11 is relatively stable. The first branch pipeline 112 can be set in three layers or according to the liquid level and the interval between the first branch pipeline 112. The main purpose of this setting is to improve the efficiency of the explosion. The gas is connected to the air inlet pipe 114 through a hose, and the explosion pipe and the aeration nozzle 101 can achieve the purpose of explosion. When the position of the explosion device needs to be changed or it needs to be lifted for maintenance, the aeration device can be pulled up by connecting the lifting ring 12 through an external lifting device.

[0021] By arranging multiple layers of first branch pipes and second branch pipes on the pipe rack, aeration can be performed at multiple positions in a three-dimensional height space, thereby improving the aeration efficiency of the aeration device.

[0022] In a preferred solution, an electric valve 13 is provided between the main pipeline 111 and the first branch pipeline 112 , and two sides of the electric valve 13 are threadedly connected to the first branch pipeline 112 and the main pipeline 111 , respectively.

[0023] The electric valve 13 can open or close the pipeline as needed, so that the aeration nozzle 101 on the corresponding pipeline can work.

[0024] In a preferred embodiment, a connecting piece 14 is provided between the first branch pipe 112 and the second branch pipe 113, and a first through hole 141 and a second through hole 142 which are perpendicular to each other are provided on the connecting piece 14. The first branch pipe 112 is installed in the first through hole 141, and the second branch pipe 113 is installed in the second through hole 142. A third through hole 143 connecting the second through hole 142 is also provided in the first through hole 141. At least two annular grooves 144 for installing sealing rings are provided in the first through hole 141 and the second through hole 142, and the third through hole 143 is arranged between the two annular grooves 144.

[0025] In this way, the gas on the first branch pipe 112 can enter the second branch pipe 113 through the third through hole 143 , and a sealing ring is arranged in the annular groove 144 to make the connection between the first branch pipe 112 and the second branch pipe 113 more airtight.

[0026] In a preferred embodiment, the connecting member 14 includes a first clamping member 145, a second clamping member 146 and a third clamping member 147. The first clamping member 145 is provided with a semicircle, the second clamping member 146 is provided with two semicircles perpendicular to each other, and the third clamping member 147 is provided with a semicircle. The semicircle of the first clamping member 145 and the semicircle of the second clamping member 146 form a second through hole 142, and the semicircle of the second clamping member 146 and the semicircle of the third clamping member 147 form a first through hole 141.

[0027] The first clamping member 145 , the second clamping member 146 and the third clamping member 147 are detachably connected via threads.

[0028] In the preferred solution, a plurality of float switches 15 are provided on the main pipe 111. The float switches 15 are arranged above the corresponding first branch pipes 112. The position of the float switches 15 is higher than the height of the second branch pipes 113 on the corresponding first branch pipes 112. The float switches 15 are used to detect whether the first branch pipes 112 are still in water, and the controller thereby controls the electric valve 13 on the first branch pipes 112 to close.

[0029] The float switch, a cleverly designed liquid level controller, is like a smart sentinel in the liquid world, accurately regulating the rhythm of water supply and drainage of the pump. It is not just a simple switch, but also an indispensable part of the automatic control system. Its core function is to transmit signals through buoyancy changes, guide the start and stop of the water pump, and realize intelligent management of the liquid level. The float switch can be selected from the ELICO cable float switch.

[0030] When the float switch 15 is underwater, due to the water pressure, the float switch 15 detects that the bracket below the float switch 15 is still in the water. The float switch 15 and the number of layers of the first branch pipe 112 correspond one to one. One float switch 15 only corresponds to one layer of the first branch pipe 112. When a float switch 15 is out of water, the controller can control the closure of a layer of the first branch pipe 112 below the float switch 15.

[0031] In a preferred solution, a pressure sensor 16 is further provided on the lowest first branch pipe 112. The pressure sensor 16 is electrically connected to the controller. The pressure sensor 16 is used to detect whether the pipe rack 11 is in contact with the underwater bottom.

[0032] The pressure sensor 16 is used to detect whether the pipe rack 11 is at the bottom of the water. Since the pipe rack 11 has a certain weight which is greater than the buoyancy of water, the pipe rack 11 sinks under the action of gravity.

[0033] Example 2 Further illustrate with reference to Example 1: An aeration system includes the mobile aeration device of any one of items 1-6, and also includes a lifting device 2, the lifting device 2 includes a boom 23 and a winch 21 arranged on the boom 23, a lifting rope 211 extended from the winch 21 is connected to a lifting ring 12 on a main pipe 111, and a clamping device 3 for clamping the main pipe 111 is also provided below the front end of the boom 23.

[0034] The lifting device 2 also includes a fixed seat 24, a rotating arm 22 is provided above the fixed seat 24, the fixed seat 24 and the rotating arm 22 are connected by a slewing bearing 25, a motor 26 with a gear is provided on the rotating arm 22, and a cylinder 27 is provided between the rotating arm 22 and the lifting arm 23.

[0035] The lifting device 2 may also be other equipment such as a crane.

[0036] In the preferred embodiment, the clamping device 3 includes a parallel clamping cylinder 31 and a clamping finger 32 arranged on the parallel clamping cylinder 31. Two V-blocks 33 are arranged on the clamping finger 32 in opposite directions. When working, the lifting rope 211 and the clamping rod 17 pass between the two V-blocks 33.

[0037] In a preferred solution, a proximity sensor 34 is provided on the clamping finger 32 . The proximity sensor 34 is electrically connected to the controller. The proximity sensor 34 is used to detect whether the clamping rod 17 reaches the clamping position of the V-shaped block 33 .

[0038] When the proximity sensor 34 detects the main pipe 111, the controller controls the clamping device 3 to clamp the main pipe 111. The main function at this time is to facilitate the rapid movement of the pipe rack 11. After all, if the pipe rack 11 is moved directly with the lifting rope 211, the pipe rack 11 will shake too much, which is not conducive to the movement of the pipe rack 11. In this way, the speed of the lateral movement of the pipe rack 11 can be increased, and the lifting device 2 can be convenient for moving the pipe rack 11 from one position to another, thereby improving the overall efficiency of the explosion.

[0039] In the preferred embodiment, Example 3 Further description is given in conjunction with Examples 1 and 2: A control method for a mobile aeration device includes a pulling-up stage and a lowering stage of the aeration device. The pulling up stage includes: the winch 21 winds up the lifting rope 211, and the aeration device slowly rises. First, the pressure sensor 16 detects that the aeration device leaves the underwater bottom. Then, the uppermost float switch 15 detects that the float switch 15 is out of the water surface. The controller controls the corresponding electric valve 13 below the float switch 15 to close, and the aeration nozzle 101 on the uppermost first branch pipe 112 stops bursting air. Then, the second float switch 15 below the first float switch 15 detects that it is out of the water surface, and controls the electric valve 13 on the lower first branch pipe 112 to close, and so on. When the aeration device leaves the water surface, the aeration nozzle 101 on the lowermost first branch pipe 112 stops bursting air, and the aeration device continues to rise. When the proximity sensor 34 detects that the main pipe 111 is at the clamping position, the winch 21 stops winching, and the controller controls the clamping device 3 to clamp the clamping rod 17. At this time, the lifting device 2 can move quickly.

[0040] The lowering stage includes: the controller controls the clamping device 3 to release the clamping rod 17, the winch 21 starts to lower the suspension rope 211, and the aeration device slowly descends. When the bottom float switch 15 detects that the bottom first branch pipe 112 has entered the water surface, the controller controls to open the electric valve 13 on the bottom first branch pipe 112, and the aeration nozzle 101 on the first branch pipe 112 starts to explode. Then the float switch 15 on the upper layer detects that the corresponding first branch pipe 112 below has entered the water. And so on. After the aeration device enters underwater, the explosion device on the top first branch pipe 112 of the aeration device starts to explode. When the pressure sensor 16 detects that the aeration device has entered the bottom of the water, the winch 21 stops lowering the aeration device.

[0041] The main purpose of controlling the aeration device in this way is to improve the efficiency of aeration. If aeration is started only after the aeration device is completely inserted into or lowered to the bottom of the pool, the start time of aeration will be much slower than this method, and the efficiency of aeration cannot be improved.

[0042] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
