The water-gas two-phase flow ejected has the characteristics of high speed, high energy, strong impact force, and long range. It can be effectively applied to storage tanks of different sizes and shapes. The water power provided by the intelligent ejector can simultaneously control the two functions of stirring and cleaning the storage tank: when the water level in the pool is high, the intelligent ejector uses the high-speed water flow ejected by the jet tube to strongly mix and stir the liquid in the pool, so that the sediment in the pool is suspended again; when the water level in the pool is low, the main function of the intelligent ejector is flushing, and the high-speed jet water is used to thoroughly flush and clean the sediment at the bottom of the pool.

DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0017] like Figure 1 The intelligent ejector with an angle control device shown in the figure comprises a submersible sewage pump 1, a bracket 2, a main shaft 3, a jet pipe assembly 4, a hydraulic motor 5, an angle control device 6, and a rotary joint 7. The jet pipe assembly 4 comprises a pressure pipeline 41 and a venturi tube 42.

[0018] The bracket 2 includes a pipeline fixing part 21 and an angle controller connecting part 22. The output port of the submersible sewage pump 1 is connected to a conduit 8, which is arranged on the pipeline fixing part 21 and communicated with the main shaft 3. The jet tube assembly 4 is fixedly connected and communicated with the main shaft 3. The main shaft 3 is connected to the conduit 8 through the rotary joint 7. The hydraulic motor 5 is arranged on the angle controller connecting part 22. The hydraulic motor 5 is connected to the main shaft 3 and can drive the main shaft 3 to drive the jet tube assembly 4 to rotate. The angle control device 6 is arranged on the angle controller connecting part 22 and is connected to the main shaft 3 and can control the rotation angle of the main shaft 3.

[0019] like Figure 2-3As shown, the angle control device 6 includes a driving gear 61, a driven gear 62, an angle sensor 63, a magnetic head 66, a bearing seat 64, and a pin 65. The driving gear 61 is connected to the main shaft 3 through a flat key sleeve. The angle sensor 63 is arranged on the upper plane of the angle controller connection part 22. The bearing seat 64 is connected to the lower plane of the angle controller connection part 22. The pin 65 has a L-shaped cross section and has a bearing seat connection part 651 and a driven gear connection part 652. The pin 65 is connected to the bearing seat 64 through the bearing seat connection part 651. The magnetic head 66 is connected to the top of the bearing seat connection part 651 and is correspondingly arranged with the angle sensor 63. There is a sensing gap between the magnetic head 66 and the angle sensor 63. The driven gear 62 is sleeved on the pin 65 and connected to the upper plane of the driven gear connection part 652. The driven gear 62 is arranged corresponding to the driving gear 61 and can rotate under the action of the driving gear 61, thereby driving the pin 65 to rotate.

[0020] The submersible sewage pump 1 and the conduit 8 , the conduit 8 and the rotary joint 7 , the main shaft 3 and the rotary joint 7 , the main shaft 3 and the pressure pipeline 41 , and the pressure pipeline 41 and the venturi tube 42 are all connected via flanges 9 .

[0021] The working principle of the intelligent injector with angle control device is as follows:

[0022] Start the equipment, the hydraulic motor 5 drives the main shaft 3 to drive the jet tube assembly 4 to rotate, and the submersible sewage pump 1 sequentially transmits high-speed water flow to the venturi tube 42 through the conduit 8, the main shaft 3, and the pressure pipeline 41. When the water level in the pool is high, the high-speed water flow sprayed by the venturi tube 42 strongly mixes and stirs the liquid in the pool, so that the sediment in the pool is suspended again; when the water level in the pool is low, the high-speed water flow sprayed by the venturi tube 42 flushes and cleans the sediment at the bottom of the pool.

[0023] At the same time, the driving gear 61 connected to the main shaft 3 rotates with the main shaft 3, thereby driving the driven gear 62 to rotate, the pin shaft 65 rotates with the driven gear 62, and the magnetic head 66 connected to the top of the bearing seat connecting part 651 of the pin shaft 65 rotates accordingly, and feeds back the position signal to the angle sensor 63 to obtain the angle information.

[0024] The feedback signal obtained can display the rotation angle of the intelligent injector in real time in the control system, and the device can be controlled to run at a fixed angle and time by manually setting the angle, so that long-term fixed-point flushing can be achieved for some areas with thicker deposits.
