Description

Technical Field

[0001] The utility model relates to the technical field of water pump control systems, in particular to a water pump combined control system. Background Art

[0002] The riverside water pumps transport river water to surrounding units to supply production water. There are generally four pumps, which are controlled by two locations. One is to start and stop on the on-site power distribution cabinet of the pump ship, and the other is to start and stop by laying two 24-core control cables through the production water main control button box to the pump ship. Since the production water main control room is too far away from the pump ship and it has to cross the riverside road, on-site operation is very inconvenient. Daily operations are mainly started and stopped on the control box in the main control room. Due to the long distance, long lines, large pressure loss, and the capacitance of the cable, misoperation is frequent. In addition, due to the settlement of the roadbed, the buried control cable is damaged and the fault point cannot be found in a short time. People can only go to the riverside pump ship to start and stop the pump manually, which is troublesome and unsafe especially at night. In view of the above reasons, the present application proposes a remote joint control system for riverside water pumps. Summary of the Invention

[0035] like Figure 1-4 As shown, the utility model proposes a water pump joint control system, the joint control system includes a main control end and a riverside water pump control end, the main control end includes a box body 1, the front of the box body 1 is rotatably provided with a limit assembly 2, a mounting groove 11 is provided below the placement plate 13 and is located on the bottom inner wall of the box body 1, the limit assembly 2 is installed in the mounting groove 11, the mounting groove 11 includes two groups of fixing bolts 21, the limiting strips 22 are sleeved on the outer ring of the fixing bolts 21, the side surface of the limiting strips 22 away from the fixing bolts 21 is fixedly connected with a fixing block 23, the inner side surface of the limiting strips 22 is in contact with the control assembly 4 and is used to limit the placement position of the control assembly 4 on the placement plate 13, the top of the limiting assembly 2 is fixedly connected with an upper cover 3, the cross section of the upper cover 3 is an "L"-shaped structure, combined with Figure 1 As shown, the upper cover 3 is provided to cover the card slot 12 and can effectively prevent dust;

[0036] A control component 4 is installed in the box 1. The control component 4 includes a switch optical terminal body and a monitoring optical fiber body. A placement plate 13 for placing the control component 4 is fixedly installed in the box 1. A slide groove 14 is provided on the placement plate 13. A slider 16 is slidingly provided in the slide groove 14. The cross-section of the slide groove 14 and the slider 16 is a "T"-shaped structure. A spring 15 is fixedly connected to both sides of the slider 16. The end of the two sets of springs 15 away from the slider 16 is fixedly connected to the inner wall of the slide groove 14. A spring 15 for sliding on the placement plate 13 is provided for the switch optical terminal body and the monitoring optical fiber body. The limiting clamping plate 17 is installed to separate the body. By setting the limiting clamping plate 17, you can adjust the space size on both sides of it. It is used to limit the installation of equipment bodies of different sizes. The switching optical terminal is a device that converts electrical signals into optical signals and sends them out. It can convert received optical signals into electrical signals and input them into the control terminal for joint control of the start and stop of the riverside water pump. The slider 16 is fixedly connected to the limiting clamping plate 17. A limiting component 2 for limiting the control component 4 is set below the limiting clamping plate 17. The limiting component 2 includes two sets of rotatable limiting strips 22;

[0037] like Figure 2As shown, a cable limiter 5 located on the top inner wall of the box body 1 is installed above the limit splint 17, and a card slot 12 is opened at the position of the cable limiter 5 on the top of the box body 1, and the card slot 12 is used to guide and place the connecting cable. The cable limiter 5 includes a connecting rod 51 fixedly connected to the box body 1, and the connecting rod 51 is a "J"-shaped structure. By pressing the cable corresponding to the gap of the connecting rod 51, the cable is pressed inside the connecting rod 51 and is located on one side of the elastic block 53. The inner wall of the connecting rod 51 is connected to the spring 2 52, and the other end of the spring 2 52 is connected to the elastic block 53. The elastic block 53 is an arc-shaped structure. The cable is stably limited and clamped in the connecting rod 51 through the setting of the spring 2 52 and the elastic block 53, so that the cables are limited and neatly arranged.

[0038] This embodiment combines Figure 3 To control the water pump, a switch optical terminal is used. This device converts electrical signals into optical signals and sends them out. At the same time, it can convert the received optical signals into electrical signals and input them into the optical terminal at the receiving end of the main control room. When the equipment is started, the relay is energized and the electrical signal is input to the switch optical terminal of the main control room, which is then output to the switch optical terminal on site through optical fiber. The switch optical terminal on site outputs an electrical signal to the on-site control box to start the riverside water pump. After the riverside water pump is started, the operating status is transmitted to the main control room in the same way, thus realizing remote control.

[0039] At the same time, when the device is in use, the limiting strip 22 is rotated synchronously by rotating the fixed block 23, so that the inner side of the limiting strip 22 is in contact with the control component 4, thereby achieving the effect of stable placement of the control component 4. Through the setting of the limiting clamp 17 and two sets of springs 15, the purpose of clamping and placing equipment of different sizes on the placement plate 13 is achieved. The connecting optical fibers and cables are arranged and limited by being clamped in the connecting rod 51, and are neatly arranged through the card slot 12, ensuring the stable connection of the equipment and the purpose of rapid maintenance.

[0040] like Figure 5 As shown in the figure, this control schematic is primarily used to control riverside water pumps, enabling the delivery of river water to surrounding units for production water supply. The system typically includes four pumps, which can be controlled from two locations.

[0041] Start and stop control of the on-site power distribution cabinet of the pump ship:

[0042] A power distribution cabinet is installed on the pump ship, and operators can start and stop the water pump directly from the cabinet. This provides convenience for on-site operations and enables quick response to actual needs.

[0043] The control components on the power distribution cabinet are connected to the electrical system of the water pump. By operating buttons, switches and other components, control signals are sent to the water pump to start or stop it.

[0044] Remote start and stop control of production water main control button box:

[0045] Two 24-core control cables are laid from the produced water main control box to the pump boat. These two cables are responsible for transmitting control signals.

[0046] Operators can remotely control the start and stop of the pumps on the pump ship from the main control button box for produced water. This remote control method allows operators to operate the pumps without having to be on the pump ship in person, improving operational convenience and safety.

[0047] Circuit components and functions

[0048] Power supply part:

[0049] There are "+24V" and "-24V" power supply labels in the figure, which provide stable operating voltage for the entire control system.

[0050] Control elements:

[0051] The components marked "K1-K8" are relays. They switch circuit states and control the flow of current.

[0052] The "SB1 T" and "SB17" components are switch buttons used to manually trigger control signals.

[0053] "KM1" and "KM3" components are contactors used to control the start and stop of the water pump motor.

[0054] The "KA5" and "KA6" components are intermediate relays used for signal conversion and amplification to enhance the reliability of control signals.

[0055] Indicating element:

[0056] "HR1", "HR2" and "HR3" in the figure are indicator lights, which are used to display the operating status, fault status and other information of the water pump, providing intuitive feedback to the operator.

[0057] Field control logic:

[0058] On the on-site power distribution cabinet of the pump ship, when the operator presses the start button, such as "SB1T", the control signal is transmitted through the contactors, relays and other components in the circuit, and finally transmitted to the water pump motor, causing it to start running. When the stop button is pressed, the corresponding control signal stops the water pump motor.

[0059] Remote control logic:

[0060] Control signals from the produced water main control box are transmitted to the pump boat via a 24-core control cable. These signals are processed by the control components in the circuit to control the start and stop of the water pump.

[0061] When the operator presses the start button on the produced water main control button box, the control signal is transmitted along the control cable to the pump boat, triggering the corresponding contactor or relay to start the water pump.

[0062] In summary, this riverside water pump control schematic diagram achieves reliable control of four water pumps at two locations through reasonable circuit design and component layout, providing effective guarantees for the transportation of river water and the supply of production water.

[0063] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
