[0002] The steady-flow intelligent water distribution and constant-pressure water injection device is an advanced equipment that integrates modern control technology, sensor technology, and mechanical technology. It is widely used in oil fields, industrial or commercial fields and consists of an automatic controller, pressure gauge, valves, pressure relief valve, pipelines, frequency conversion control system, water pump unit and complete set of accessories.

[0003] When this system is used, it can monitor the pressure changes in the pipeline network in real time and feed the signal back to the automatic controller. It compares the preset pressure value with the actual pressure value and adjusts the speed of the water pump or opens and closes the valve to maintain a constant pressure in the pipeline network. In this process, multiple water pumps are required to pump the water.

[0004] According to the Chinese patent publication CN208473815U, "An Imported Constant Pressure and Stable Flow Water Injection Device," it is mainly described as a device that can be prefabricated and assembled in the factory, with a small size, simple structure, convenient on-site installation, and small footprint. Pressure and flow control parameters are set on an intelligent electronic regulator to adapt to the pressure and flow requirements of various water injection wells. The intelligent electronic regulator can communicate with the well site RTU or the station DCS to achieve digital management of water supply pressure and flow. Compared with conventional water injection flow control devices, it reduces the investment in water injection projects. However, during this process, some pipe fittings may experience dry running when connected to a centrifugal water pump, leading to cavitation.

[0005] Therefore, a steady-flow intelligent water distribution and constant-pressure water injection device is proposed to solve the problem that some pipe fittings may run dry when connected to a centrifugal water pump, leading to cavitation. Utility Model Content

[0006] The technical problem to be solved by this utility model is that some pipe fittings may run dry when connected to a centrifugal water pump, which leads to cavitation. Therefore, a steady flow intelligent water distribution and constant pressure water injection device is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a constant flow intelligent water distribution and constant pressure water injection device, including a water guide pipe, a water inlet pipe, a butterfly valve, an impeller box, and a pressure tank. A sealing plate is in contact with one side of the impeller box, and a servo motor is fixedly connected to the sealing plate. A pipe fitting is fixedly connected to the upper end of the impeller box, and a water collection pipe is fixedly connected to one end of the pipe fitting and the two pipes are internally connected. A pressure tank is fixedly connected to one end of the water collection pipe. A water distribution pipe is evenly fixedly connected to one side of the water collection pipe, and an alarm device is fixedly connected to one side of the water distribution pipe. Protruding strips are fixedly connected to the four mutually distant sides of the impeller box. A through hole is opened on the protruding strip and a spring rod is inserted into the through hole. The end of the spring rod is in contact with the sealing plate.

[0008] As a preferred technical solution of this utility model, a pressure sensor is fixedly connected to the water distribution pipe on one side of the alarm device. The pressure sensor is connected to a servo motor through a wire. The pressure sensor monitors the status of the water distribution pipe and controls the rotation of the servo motor.

[0009] As a preferred technical solution of this utility model, a connecting ring is fixedly connected to one side of the sealing plate. The connecting ring is made of rubber and corresponds to one side of the impeller box. The sealing between the sealing plate and the impeller box is achieved by setting the connecting ring.

[0010] As a preferred technical solution of this utility model, a water inlet pipe is fixedly connected to the bottom side of the impeller box, and a temporary water tank is fixedly connected to one end of the water inlet pipe. By setting up the water inlet pipe and the temporary water tank, the impeller can be prevented from running dry.

[0011] As a preferred technical solution of this utility model, an air pump is fixedly connected to the upper end of the temporary water tank. The output end of the air pump is located inside the temporary water tank. By setting the air pump, the pressure can be increased to the temporary water tank, so that the water in the temporary water tank can enter the impeller box.

[0012] This utility model has the following advantages: by setting an impeller box on the water inlet pipe and cooperating with a protrusion and a spring rod, a limiting sealing plate can be set, which facilitates the disassembly of the servo motor for maintenance. At the same time, by setting a temporary water tank, a water inlet pipe and an air pump, the water in the impeller box can be kept full when the impeller is running, thus avoiding the problem of the impeller running dry.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The illustrated intelligent water distribution and constant pressure water injection device includes a water guide pipe 1, an inlet pipe 2, a butterfly valve 3, an impeller box 4, and a pressure tank 8. A servo motor 6 drives an impeller located inside the impeller box 4. A sealing plate 5 is in contact with one side of the impeller box 4, and the servo motor 6 is fixedly connected to the sealing plate 5. A pipe fitting is fixedly connected to the upper end of the impeller box 4, and a water collection pipe 7 is fixedly connected to one end of the pipe fitting, with internal communication. The pressure tank 8 is fixedly connected to one end of the water collection pipe 7. Water distribution pipes 9 are evenly fixedly connected to one side of the water collection pipe 7, and an alarm device 10 is fixedly connected to one side of the water distribution pipe 9. Protrusions 12 are fixedly connected to the four mutually distant sides of the impeller box 4. Through holes are opened on the protrusions 12, and spring rods 13 are inserted into the through holes. The end of the spring rod 13 contacts the sealing plate 5. By pulling the spring rod 13, the end of the spring rod 13 can enter the through hole of the protrusion 12, thereby allowing the sealing plate 5 to be detached, facilitating the disassembly of the servo motor 6 for maintenance.

[0019] The servo motor 6 is connected to the pressure sensor 11 via a wire. The pressure sensor 11 is fixedly connected to the water distribution pipe 9. The alarm device 10 is a buzzer. The alarm device 10 is located on one side of the pressure sensor 11 and the two are connected by a wire. By setting the pressure sensor 11 to monitor the state inside the water distribution pipe 9, when the hydraulic pressure inside the water distribution pipe 9 is low, it can transmit a signal to the servo motor 6 and drive the impeller to rotate to supply water. At the same time, it transmits a signal to the alarm device 10, causing the alarm device 10 to sound.

[0020] The impeller box 4 is connected to the connecting ring 17 on one side. The connecting ring 17 is fixedly connected to the sealing plate 5 on one side. The connecting ring 17 is made of rubber. By setting the connecting ring 17, the sealing performance can be improved when the sealing plate 5 is connected to the impeller box 4.

[0021] The temporary water tank 15 is fixedly connected to one end of the water inlet pipe 14, and the water inlet pipe 14 is fixedly connected to the bottom side of the impeller box 4. By setting up the temporary water tank 15 and the water inlet pipe 14, water can be supplied to the impeller box 4, thus preventing the impeller from running dry.

[0022] The temporary water tank 15 is equipped with the output end of the air pump 16. The air pump 16 is fixedly connected to the upper end of the temporary water tank 15. By setting the air pump 16, pressure can be provided on the upper side of the impeller box 4, so that water can enter the impeller box 4.

[0023] Working principle: Water enters through the inlet pipe 2 from the guide pipe 1, and then, guided by the impeller, enters the pressure tank 8 and the collecting pipe 7. The water is then diverted into the distribution pipe 9. When the water pressure in the distribution pipe 9 is insufficient, the pressure sensor 11 monitors the pressure and transmits a signal to the servo motor 6 and the air pump 16. The air pump 16 then draws ambient air into the temporary water tank 15, causing the water in the temporary water tank 15 to enter the impeller box 4 through the inlet pipe 14. The servo motor 6 then drives the impeller to rotate, and water begins to enter the collecting pipe 7 and the distribution pipe 9, thus stabilizing the pressure inside the pipes. If the servo motor 6 malfunctions, the spring rod 13 can be pulled so that its end enters the through hole of the protrusion 12. At this time, the sealing plate 5 and the servo motor 6 can be disassembled for easy maintenance.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
