Description

Technical Field

[0001] The present invention belongs to the technical field of storage tank flushing and spraying equipment, and in particular relates to a 3D rotating injector. Background Art

[0002] A storage tank is a rainwater collection facility mainly used to temporarily store the peak flow of rainwater runoff. After the maximum flow rate drops, the rainwater is slowly discharged from the storage tank, achieving the purpose of avoiding rainwater flood peaks, improving rainwater utilization rate, and controlling the pollution of the initial rainwater to the receiving water body. The existing flushing of storage tanks is very inconvenient and dangerous, especially for rain and sewage storage tanks; the ventilation effect in the storage tank is poor, there is insufficient oxygen and hydrogen sulfide gas, and it is very dangerous for personnel to flush inside the storage tank. The existing methods for flushing storage tanks are as follows:

[0003] I. Manual flushing:

[0004] 1. Ventilate the storage tank and detect whether the contents of hydrogen sulfide and oxygen are normal.

[0005] 2. Arrange cleaning personnel to wear protective equipment such as long boots, gloves and raincoats.

[0006] 3. Use a high-pressure flushing machine or manual scrubbing to remove the sludge and sundries on the pool wall and bottom of the pool.

[0007] 4. Then rinse with clean water for a second time to thoroughly remove the sludge and dirty water.

[0008] Especially for large storage tanks, the cleaning is time-consuming, laborious, wasteful of manpower and financial resources and dangerous.

[0009] II. Vacuum flushing

[0010] 1. Use the water storage chamber to evacuate and store water. After the storage tank is emptied, release the vacuum degree, and the water quickly flows out from the water storage chamber to flush the storage tank or corridor.

[0011] III. Flushing door flushing

[0012] 1. Also use the water storage chamber to overflow and store water. After the storage tank is emptied, quickly open the flushing door, and the water quickly flows out from the water storage chamber to flush the storage tank or corridor. Both vacuum flushing and flushing door flushing can perform local flushing, but some parts cannot be flushed and the flushing is not thorough. Summary of the Invention

[0013] In view of the problems existing in the above background art, the present invention provides a 3D rotating injector with high flushing pressure, long range and wide flushing range.

[0014] To this end, the present invention adopts the following technical solutions: a 3D rotating injector, which is arranged in a storage tank or a culvert.

The base is fixedly installed, and a water inlet pipeline is arranged on the base and fixed by a flange. The horizontal rotating actuator is arranged on the base, the vertical rotating actuator is arranged on the horizontal rotating actuator, and the injector is connected to the tail of the vertical rotating actuator; the water inlet pipeline is connected to the horizontal rotating actuator through the base.

[0015] The present invention can achieve the following beneficial effects: The 3D intelligent rotating injector of the present invention is installed in a storage tank or a culvert.
