Description

Technical Field

[0001] The utility model relates to the technical field of injectors, and more specifically, to an electric intelligent injector. Background Art

[0002] Electric intelligent ejector, also known as: ejector, jet vacuum pump, jet vacuum ejector, jet pump, water ejector, vacuum ejector, is a vacuum obtaining device that uses fluid to transfer energy and mass. It uses water flow with a certain pressure to eject through nozzles that are symmetrically distributed with a certain side inclination and converge at a focus. Since the jet water flow rate is particularly high, the pressure energy is converted into velocity energy, which reduces the pressure in the suction area to produce a vacuum. The working fluid of the ejector can be gas and liquid.

[0003] At present, in the regulating reservoir and other related industries, the flushing part of the regulating reservoir receiving pool is flushed by the ejector; the power is driven by a hydraulic motor to achieve plane corner flushing.

[0004] However, in actual use, firstly, since it is a hydraulic system, it requires a hydraulic pump station, a hydraulic motor, a hydraulic oil pipe, various hydraulic components, hydraulic oil, etc., which greatly increases the failure rate; secondly, the power is driven by a hydraulic motor. Since the ejector swings left and right to flush, it is always a repeated reciprocating motion, so the drive inside the hydraulic motor is always a repeated gear drive engagement, which is easy to cause damage; finally, the hydraulic oil pipes and joints are prone to leakage, causing pollution.

[0029] For further information, please refer to the attached manual. Figure 4 , 5 A support plate 9 is fixed to one side of the main frame 1, and a support assembly 10 is provided between the support plate 9 and the venturi vacuum ejector 3; the support assembly 10 includes an arc track 101 and a T-shaped bracket 102, the bottom of the T-shaped bracket 102 slides in the arc track 101, a first pulley 103 is provided at the bottom of the T-shaped bracket 102, and second pulleys 104 are provided on both sides of the T-shaped bracket 102, and the second pulley 104 is located on the upper surface of the arc track 101.

[0030] Furthermore, L-shaped push plates 105 are provided on both sides of the T-shaped bracket 102 , and the two L-shaped push plates 105 are both located inside the arc track 101 .

[0031] It should be noted that when the T-shaped bracket 102 drives the L-shaped push plate 105 to move, the L-shaped push plate 105 moves along the inner wall of the arc track 101 , which can remove impurities inside the arc track 101 and prevent the arc track 101 from being blocked.

[0032] Furthermore, the number of the first pulleys 103 is set to be multiple, and the first pulley 103, the second pulley 104 and the T-shaped bracket 102 are all connected by screws.

[0033] Furthermore, two support rods 106 are connected between the arc track 101 and the main frame 1 , and the two support rods 106 are both connected to the side surfaces of the main frame 1 .

[0034] Furthermore, an arc plate 107 is provided inside the T-shaped frame, and the arc plate 107 is fixedly connected to the T-shaped bracket 102 .

[0035] It should be noted that, since the cross section of the arc plate 107 is concave, it can fit the outer side of the Venturi vacuum ejector 3, and the gap between the Venturi vacuum ejector 3 and the T-shaped frame can be reduced.

[0036] Working principle: First, start the submersible pump 2, which sprays water through the water pipe 5, the L-shaped water pipe 7, the pressure pipe 4 and the Venturi vacuum ejector 3 to flush the inside of the pool;

[0037] Next, the amphibious explosion-proof motor 61 and the reducer 62 are started to drive the first connecting rod 114 and the first gear 112 to rotate, which can drive the second gear 113 to rotate on the second connecting rod 115, which can drive the L-shaped water pipe 7, the pressure pipeline 4 and the venturi vacuum ejector 3 to rotate, which can increase the injection range of the venturi vacuum ejector 3, and the rotation angle of the second connecting rod 115 is detected by the angle sensor 111, and then the positive and negative rotation of the amphibious explosion-proof motor 61 is controlled by the controller, so as to control the injection angle range of the venturi vacuum ejector 3;

[0038] Then, when the Venturi vacuum ejector 3 swings, it generates power for the T-shaped bracket 102, causing it to slide on the arc track 101, and driving the first pulley 103 and the second pulley 104 to move inside and above the arc track 101, respectively, which can reduce the friction between the T-shaped bracket 102 and the arc track 101. The T-shaped bracket 102 can support the Venturi vacuum ejector 3 to keep it moving horizontally, which can prevent the connection between the Venturi vacuum ejector 3 and the pressure pipeline 4 and the L-shaped water pipe 7 from being unevenly loaded and loosened, thereby avoiding damage to the Venturi vacuum ejector 3;

[0039] When the T-shaped bracket 102 moves inside the arc track 101 , it drives the L-shaped push plates 105 on both sides to move, so as to push away the impurities deposited inside the arc track 101 , thereby preventing the arc track 101 from being blocked and affecting the movement of the T-shaped bracket 102 .

[0040] The utility model is driven by an amphibious explosion-proof motor 61 to flush within a 2D space, and uses an angle sensor 111 to transmit signals so that flushing can be automatically achieved in the area responsible for each ejector; the T-shaped bracket 102 cooperates with the arc track 101 to support and protect the Venturi vacuum ejector 3.

[0041] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
