[0046] Embodiment 2

[0047] In one embodiment, a cementing water tank is provided. Figure 1 As shown, the cementing water tank includes a water tank body 1 and a plurality of pipelines, each of the pipelines is connected to the water tank body 1, and also includes the cementing water tank control system described in any of the above embodiments.

[0048] In this embodiment, by arranging a liquid level gauge in the water tank body 1, it is possible to realize automatic measurement of the liquid level in the water tank body 1, and then realize automatic adjustment of the liquid level in the water tank body 1 by controlling the electric valve module and the electric pump 12 through the control module, thereby effectively improving the efficiency of liquid level measurement and the efficiency of liquid level adjustment.

[0049] In one embodiment, if Figure 1 and Figure 2 As shown, the cementing water tank also includes a water storage tank 13, each of the pipelines includes a drainage pipeline 7, a discharge pipeline 8 and a water inlet pipeline 3, and each of the electric valve modules includes a first electric valve module 14, a second electric valve module 9 and a third electric valve module 11; one end of the drainage pipeline 7 is connected to the water storage tank 13, the other end of the drainage pipeline 7 is connected to the first end of the electric pump 12, the second end of the electric pump 12 is connected to one end of the water inlet pipeline 3, the other end of the water inlet pipeline 3 is connected to the water tank body 1, one end of the discharge pipeline 8 is connected to the water tank body 1, the other end of the discharge pipeline 8 is connected to the water storage tank 13, and the discharge pipeline 8 is connected to the bottom of the water tank body 1 or a position close to the bottom; the first electric valve module 14 is arranged on the drainage pipeline 7, the second electric valve module 9 is arranged on the discharge pipeline 8, and the third electric valve module 11 is arranged on the water inlet pipeline 3.

[0050] In this embodiment, the water tank 13 and the water tank body 1 are both arranged on the base 17. The first electric valve module 14 is used to open or close the drainage pipeline 7, the second electric valve module 9 is used to open or close the water discharge pipeline 8, and the third electric valve module 11 is used to open or close the water inlet pipeline 3. The water tank 13 is used to provide a water source for the water tank body 1, and is also used to recover the water of the water tank body 1, so as to replenish the water source for the water tank body 1, and to adjust the liquid level in the water tank body 1, and to realize the circulation of water. Specifically, the drainage pipeline 7 is used to realize the circulation of water between the water tank 13 and the electric pump 12, and the first end of the electric pump 12 can be used as an input end or an output end. When the first end of the electric pump 12 is the input end, the electric pump 12 draws the water of the water tank 13 into the drainage pipeline 7, and transports it to the water tank body 1 through the second end of the electric pump 12. At this time, the second end of the electric pump 12 is the output end, and the first electric valve module 14 opens the valve, and the third electric valve module 11 opens the valve. The drain line 8 is used to drain the water in the water tank body 1 to the water storage tank 13 to lower the water level in the water tank body 1. Specifically, when the second electric valve module 9 is turned on, the drain line 8 is opened. Since the drain line 8 is connected to the bottom of the water tank body 1 or a position close to the bottom, it is beneficial for the water in the water tank body 1 to be drained to the water storage tank 13 through the drain line 8. In this way, the water in the water storage tank 13 can be pumped into the water tank body 1 by the electric pump 12, and the water in the water tank body 1 can also flow back to the water storage tank 13.

[0051] In one embodiment, if Figure 1 and Figure 2 As shown, the cementing water tank also includes a circulation pipeline 4 and a fourth electric valve module 10; one end of the circulation pipeline 4 is connected to the water tank body 1, and the other end of the circulation pipeline 4 is connected to the third end of the electric pump 12; the fourth electric valve module 10 is arranged on the circulation pipeline 4.

[0052] In this embodiment, when the first end of the electric pump 12 is used as the output end, the third end of the electric pump 12 is used as the input end. The electric pump 12 draws water into the water tank body 1 through the circulation pipeline 4, and delivers it to the water storage tank 13 through the first end of the electric pump 12 and the drainage pipeline 7. In this way, the electric pump 12 delivers water to the water tank body 1 through the water inlet pipeline 3, and draws the water bucket in the water tank body 1 back to the water storage tank 13 through the circulation pipeline 4, thereby realizing the circulation of water. It should be understood that since the electric pump 12 is connected to the water storage tank 13 only through the drainage pipeline 7, the valves in the water inlet pipeline 3 and the circulation pipeline 4 cannot be opened at the same time. When the water inlet pipeline 3 is filled with water, the first electric valve module 14 opens the drainage pipeline 7, and the water in the drainage pipeline 7 flows in one direction. The water in the drainage pipeline 7 flows from the water storage tank 13 to the electric pump 12, and the fourth electric valve module 10 is closed to prevent the circulation pipeline 4 from conveying water. When the circulation pipeline 4 transports water, the first electric valve module 14 opens the drainage pipeline 7, and the drainage pipeline 7 flows in one direction. The water in the drainage pipeline 7 flows to the water storage tank 13 through the electric pump 12, and the third electric valve module 11 is closed to prevent water from being transported into the water inlet pipeline 3.

[0053] In one embodiment, the cementing water tank also includes a venting pipeline 2 and a fifth electric valve module 18, the venting pipeline 2 is connected to the water tank body 1, and the venting pipeline 2 is connected to a position near the top of the water tank body 1, and the fifth electric valve module 18 is arranged on the venting pipeline 2.

[0054] In this embodiment, the fifth electric valve module 18 is used to open or close the deflation pipeline 2, and the deflation pipeline 2 is used to discharge the air in the water tank body 1. When the water inlet pipeline 3 injects water into the water tank body 1, the fifth electric valve module 18 opens the valve, and the deflation pipeline 2 is opened, so that the air in the water tank body 1 is discharged, so that the water in the water inlet pipeline 3 can be injected into the water tank body 1. It is worth mentioning that since the deflation pipeline 2 is connected to a position near the top of the water tank body 1, the deflation pipeline 2 is not easily submerged by water, so that the deflation pipeline 2 can remain unobstructed.

[0055] In one embodiment, the cementing water tank further includes a light-transmitting tube 19 , the axial direction of the light-transmitting tube 19 is arranged along the vertical direction, and the light-transmitting tube 19 is connected to the water tank body 1 so that the liquid level in the light-transmitting tube 19 is flush with the liquid level in the water tank body 1 .

[0056] In this embodiment, the light-transmitting tube 19 may also be called a transparent tube. The light-transmitting tube 19 enables the user to observe the liquid level in the light-transmitting tube 19. Specifically, a scale is provided on the side wall of the light-transmitting tube 19. In one embodiment, the length of the light-transmitting tube 19 is equal to the length of the water tank body 1, and the head and tail of the light-transmitting tube 19 are aligned with the head and tail of the water tank body 1. In this way, since the light-transmitting tube 19 is connected to the water tank body 1, the liquid level in the light-transmitting tube 19 is flush with the liquid level in the water tank body 1. By observing the liquid level of the light-transmitting tube 19, the liquid level of the water tank body 1 can be conveniently viewed.

[0057] Embodiment 3

[0058] The present invention is realized by the following measures: A cementing water tank intelligent control system is divided into four systems, a gate valve automatic control system, a data measurement and acquisition system, a data wireless transmission system, a data control terminal and a display system.

[0059] The gate valve automatic control system can wirelessly control the opening and stopping of the five adjustable wireless controlled electric actuators and the electric explosion-proof centrifugal pump of the water tank, and can implement automatic and manual control of water inlet, water outlet, internal water circulation, exhaust and other processes.

[0060] The gate valve automatic control system is mainly based on the wireless remote control system of GPRS data transmission to control the opening and stopping of five adjustable wireless control electric actuators and electric explosion-proof centrifugal pumps. Users use mobile phones and other terminals to send start and stop instructions to the five adjustable wireless control electric actuators and electric explosion-proof centrifugal pumps through the GPRS transmission system. After receiving the instructions, the five adjustable wireless control electric actuators and electric explosion-proof centrifugal pumps perform start and stop actions and feedback the execution status to mobile phones and other terminals; the execution status also enters the central data control terminal through the GPRS transmission system, and realizes wireless remote control on the network server and its dedicated management software (cementing cloud platform).

[0061] Five adjustable wireless controlled electric actuators and electric explosion-proof centrifugal pumps organically combine the encoding units and transmitting units of each wireless transmission with the receiving units and decoding units, and organically combine the independent GPRS DTU wireless control terminals with the PLC controller. The GPRS wireless control terminal on the mobile phone can effectively realize the integrated control of GPRS remote monitoring, mobile phone control and RS485 communication with PLC, and build an integrated switch control module, which can effectively realize the remote input of input commands and the wireless transmission of output signals.

[0062] The data measurement and acquisition system can measure the real-time liquid level of the water tank through four ultrasonic level meters to obtain the water volume in each water tank, and transmit the data to the central data control terminal in real time through the GPRS wireless module, and realize wireless remote control on the network server and its dedicated management software (cementing cloud platform). If the liquid level is too low, the prompt "Warning Attention - Liquid Level Too Low" will be transmitted in real time.

[0063] The data wireless transmission system is a system that combines GPRS wireless module and PLC to remotely control the liquid level information in each water tank, five adjustable wirelessly controlled electric actuators and the real-time opening information of the electric explosion-proof centrifugal pump via GPRS.

[0064] The data control terminal and display system are operated and controlled through the user operation terminal, and can be operated and controlled in real time on mobile phones and PCs.

[0065] like Figure 1 and Figure 2 As shown, the water tank includes a water tank 1, a venting pipeline 2, a water inlet pipeline 3, a circulation pipeline 4, an ultrasonic liquid level meter 5 / 6 / 15 / 16, a drainage pipeline 7, a drain pipeline 8, a drain pipeline regulating wireless control electric actuator 9, a circulation pipeline regulating wireless control electric actuator 10, a water inlet pipeline regulating wireless control electric actuator 11, an electric explosion-proof centrifugal pump 12, a water storage tank 13, a drainage pipeline regulating wireless control electric actuator 14, a base 17, a venting pipeline regulating wireless control electric actuator 18, and an external transparent pipeline 19.

[0066] The existing technology cannot realize the real-time display of the water tank liquid level on the wireless terminal, nor can it experiment with the automatic switching of the remotely controlled electric pump and the five adjustable wirelessly controlled electric actuators, and cannot meet the requirements of automation, visualization and intelligence in future cementing projects.

[0067] According to the above requirements, the electric explosion-proof centrifugal pump 12 , the water storage tank 13 , and the water tank 1 in the present invention are all fixed on the base 17 .

[0068] The bleed line 2 is provided with a bleed line regulating wireless control electric actuator 18 .

[0069] A drainage pipeline regulating type wireless control electric actuator 14 is installed on the drainage pipeline 7 .

[0070] A water discharge line regulating wireless control electric actuator 9 is installed on the water discharge line 8 .

[0071] A water inlet pipeline regulating type wireless control electric actuator 11 is installed on the water inlet pipeline 3 .

[0072] A circulating pipeline regulating type wireless control electric actuator 10 is installed on the circulating pipeline 4 .

[0073] The venting pipeline regulating wireless control electric actuator 18, the drainage pipeline regulating wireless control electric actuator 14, the drain pipeline regulating wireless control electric actuator 9, the water inlet pipeline regulating wireless control electric actuator 11, and the circulation pipeline regulating wireless control electric actuator 10 installed on the water inlet pipeline 3 can realize three control modes: remote control, on-site control, and bus-type centralized control. The remote valve opening and closing signals can receive three valid signals: DC24V, AC220V, and AC380V. The electric actuator control module receives the control signal from the remote control room and transmits it to the main control CPU after photoelectric isolation and anti-shake processing. The CPU monitors and collects the actuator status signal in real time, controls the motor to drive the controlled valve, and continuously collects the valve position signal in real time through the high-precision potentiometer or JUE value encoder to achieve precise control of the valve. At the same time, the real-time data is transmitted to the remote control end. The electric actuator control module has advanced principles, comprehensive functions, long-term stability and reliability, high integration, low heat generation, convenient loading and unloading, and simple maintenance. It can be quickly and non-intrusively set up via the infrared remote control or the operation panel buttons.

[0074] A pair of lifting lugs are installed on the top of the water tank 1. There are 4 ultrasonic level meters on the top of the water tank 1 that can realize wireless data collection, which can collect the liquid level data in the water tank in real time. Transparent plastic tubes are fixed on the bottom and outside of the water tank 1 to observe the liquid level position in real time for calibrating the water volume data in the tank.

[0075] The venting pipeline 2 and the venting pipeline regulating wireless control electric actuator 18 can realize remote or manual control of valve switching. When water needs to be added, drained or released in the tank, it needs to be opened remotely or manually to realize the above functions.

[0076] The water inlet pipeline 3 and the water inlet pipeline regulating wireless control electric actuator 11 can realize remote or manual control of valve switching. When water needs to be added to the tank, it needs to be opened remotely or manually to realize the above function.

[0077] The circulation pipeline 4 and the circulation pipeline regulating wireless control electric actuator 10, in cooperation with the drainage pipeline 7 and the drainage pipeline regulating wireless control electric actuator 14, the drain pipeline 8 and the drain pipeline regulating wireless control electric actuator 9, can realize remote or manual control of the circulation pipeline regulating wireless control electric actuator 10, the drainage pipeline regulating wireless control electric actuator 14, and the drain pipeline regulating wireless control electric actuator 9 switches, so as to realize the internal circulation function of the water in the tank remotely or manually controlled.

[0078] The drainage pipeline 7 and the drainage pipeline regulating wireless control electric actuator 14, the drain pipeline 8 and the drain pipeline regulating wireless control electric actuator 9 can remotely or manually control the switches of the drainage pipeline regulating wireless control electric actuator 14 and the drain pipeline regulating wireless control electric actuator 9 to realize the function of remotely or manually controlling the discharge of water in the tank.

[0079] The present invention relates to an intelligent control system for cementing water tanks. It can realize remote or manual control of the gate valves of cementing water tanks during the entire cementing process, accurately measure the amount of water in cementing water tanks, and directly display the amount of water in each water tank on mobile phones and computer terminal systems, thereby achieving the purpose of automated visualization.
