Description

Technical Field

[0001] The utility model relates to the technical field of underwater hydraulic control, in particular to a proportional drive valve box controlled by an underwater integrated bus. Background Art

[0002] Proportional valves are common components in industries such as industry, medical devices, food processing, and robotics. Unlike solenoid valves, which are either fully open or fully closed, proportional valves can adjust their opening. Therefore, they are often used in precise control applications, such as flow or pressure control. The actuation method for proportional valves is generally more complex than that of solenoid valves. The key to proportional valve actuation is establishing a functional relationship between the control signal (such as voltage, current, and duty cycle) and the valve opening (or its equivalent, flow rate). Because proportional valves can precisely control flow and pressure, they are widely used in underwater robotic operations and underwater oil drilling systems. Conventional underwater hydraulic system valve manifolds use independent amplifiers to drive proportional valves. Each proportional valve in the manifold requires a separate drive amplifier connected to the controller, which then communicates with an external host computer via an I / O interface. This means that each proportional valve requires a separate drive circuit and a separate controller for communication with the external host computer. The more proportional valves connected in series, the more wiring increases, the more complex the drive circuit, and the more watertight joints are required, resulting in poor overall sealing and waterproofing performance.

[0048] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Example 1:

[0050] This embodiment provides a proportional drive valve box controlled by an underwater integrated bus, such as Figure 1 As shown, it includes: a box 1, an oil circuit block 2, multiple proportional valves 3, a controller 4 and a watertight connector 5, wherein:

[0051] The oil circuit block 2 is arranged inside the box 1, and the multiple proportional valves 3 are located inside the box 1 and arranged on the oil circuit block 2, and all the proportional valves 3 are connected to the oil circuit block 2; the controller 4 is arranged inside the box 1, and all the proportional valves 3 are connected to the controller 4 through a bus. The watertight connector 5 is arranged on the box 1, and the lower end of the watertight connector 5 is located inside the box 1. The lower end of the watertight connector 5 is connected to the controller 4, and the upper end of the watertight connector 5 is located outside the box 1. The upper end of the watertight connector 5 is used to be electrically connected to an external device; the adjustment of the internal flow of the oil circuit block 2 is achieved by controlling each proportional valve 3.

[0052] The controller 4 may be a programmable logic controller (PLC).

[0053] In this embodiment, an underwater integrated bus is used to control a proportional drive valve box to serve as a transition device for transmitting oil between an upstream oil storage device and a downstream oil storage device, and to adjust the oil transmission rate between the upstream oil storage device and the downstream oil storage device. The box 1 is used to accommodate most of the components in the device and to isolate the components inside the box 1 from the outside world. Since the device provided in this embodiment needs to be used underwater, the box 1 also needs to be waterproof to prevent external water from entering the box 1 and damaging the internal components. The oil circuit block 2 is used to store oil and supply oil flow. The proportional valve 3 is used to adjust the opening of its own valve core to adjust the oil flow rate. While the oil transmission diameter remains unchanged, the oil transmission rate between the upstream oil storage device and the downstream oil storage device is adjusted.

[0054] In this embodiment, the plurality of proportional valves 3 are connected to the controller 4 via a bus. The controller 4 drives each proportional valve 3 via feedback from a pulse width modulation inverter (PWMI). The controller 4 is then electrically connected to external devices via a watertight connector 5. In this embodiment, signals can be output to the outside via a bus such as CAN, RS232, DP, or TCTIP to control each proportional valve 3 or other devices.

[0055] Compared with the prior art, each proportional valve 3 requires separate wiring and an external connector to control each proportional valve 3, resulting in too many external connectors in the drive valve box and poor overall sealing and waterproof performance. The multiple proportional valves 3 described in this embodiment are connected to the controller 4 via a bus, and the controller 4 uploads and sends data to each proportional valve 3 separately via the bus. Due to the characteristics of the bus protocol itself, the corresponding data of all proportional valves 3 are transmitted on the bus, but each data is only associated with and sent to the corresponding proportional valve 3, and the non-corresponding proportional valves 3 are shielded, thereby achieving corresponding uploading and sending of each data. At the same time, the controller 4 can achieve electrical connection with external devices through only one watertight connector 5, avoiding separate wiring and setting of external connectors for each proportional valve 3. On the one hand, this simplifies the overall circuit. On the other hand, the number of connectors on the watertight connector 5 is far less than the external connectors required to be set separately for each proportional valve 3, thereby greatly reducing the number of external connectors and improving the overall sealing and waterproof performance.

[0056] In this embodiment, in the driving valve box, the proportional valve 3 is divided into two types: a proportional solenoid valve 31 and a proportional relief valve 32. Therefore, this embodiment also involves the following designs:

[0057] like Figure 2 As shown, the plurality of proportional valves 3 include a plurality of proportional solenoid valves 31 and a plurality of proportional relief valves 32, wherein:

[0058] The plurality of proportional solenoid valves 31 and the plurality of proportional relief valves 32 are all provided on the oil circuit block 2 and are in communication with the oil circuit block 2 ; the plurality of proportional solenoid valves 31 and the plurality of proportional relief valves 32 are all connected to the controller 4 via a bus.

[0059] In this embodiment, the proportional solenoid valve 31 is used to proportionally control the flow rate of the oil in the hydraulic transmission system, enabling proportional control of the output speed of hydraulic actuators such as hydraulic cylinders and hydraulic motors. The proportional relief valve 32 is used to adjust the flow rate and pressure of the oil fluid by adjusting the size of the relief valve opening, thereby achieving precise flow and pressure control. In this embodiment, the connection between the proportional solenoid valve 31 and the proportional relief valve 32 and the oil block 2 is also additionally sealed and reinforced to prevent leakage of the oil in the oil block 2. In this embodiment, the seal reinforcement can be made of a highly corrosion-resistant material such as nitrile rubber.

[0060] Furthermore, the box body 1 needs to be provided with corresponding liquid outlets and liquid inlets, which are connected to the oil circuit block 2 for connecting to the upstream oil storage device and the downstream oil storage device respectively, thereby realizing the transmission of oil. Therefore, this embodiment also involves the following designs:

[0061] like Figure 2As shown, the underwater integrated bus controlled proportional drive valve box further includes at least one liquid inlet pipe joint 61 and multiple liquid outlet pipe joints 62, wherein:

[0062] The at least one liquid inlet pipe joint 61 is arranged on the side end face of the box body 1, and the liquid inlet pipe joint 61 passes through the side end face of the box body 1 and is connected to the oil circuit block 2. The liquid inlet pipe joint 61 is used to be connected to the upper oil storage device, and is used to transport the liquid in the upper oil storage device to the oil circuit block 2; the multiple liquid outlet pipe joints 62 are arranged on the lower end face of the box body 1, and the liquid outlet pipe joints 62 pass through the lower end face of the box body 1 and are connected to the oil circuit block 2. The liquid inlet pipe joint 61 is used to be connected to the lower oil storage device, and is used to transport the liquid in the oil circuit block 2 to the lower oil storage device.

[0063] Furthermore, when the valve box is driven to operate underwater, it is necessary to monitor the pressure inside the device in real time and compensate for the pressure inside the device in real time to ensure that the pressure inside the device is relatively stable and that all components in the device are intact and operate stably. Therefore, this embodiment also involves the following designs:

[0064] like Figure 3 As shown, the underwater integrated bus-controlled proportional drive valve box also includes a pressure compensator 7 and a pressure sensor 8, wherein: the pressure compensator 7 is arranged on the side end face of the box body 1, one end of the pressure compensator 7 is located outside the box body 1, and the other end of the pressure compensator 7 is located inside the box body 1; the pressure sensor 8 is arranged on the inner wall of the box body 1; the pressure sensor 8 is connected to the controller 4 through a bus, the pressure sensor 8 is used to monitor the pressure changes inside the box body 1, and the pressure compensator 7 is used to adjust the pressure inside the box body 1.

[0065] In this embodiment, the pressure compensator 7 can adaptively adjust the internal pressure of the box body 1 according to the internal pressure of the box body 1 and the pressure outside the box body 1, thereby ensuring that the pressure inside the device is relatively stable.

[0066] Furthermore, since the device needs to work underwater, it is also necessary to monitor the temperature and humidity inside the box 1 in real time. Therefore, this embodiment also involves the following designs:

[0067] like Figure 3 As shown, the underwater integrated bus-controlled proportional drive valve box also includes a temperature and humidity sensor 9, wherein: the temperature and humidity sensor 9 is arranged on the inner wall of the box body 1; the temperature and humidity sensor 9 is connected to the controller 4 through a bus, and the temperature and humidity sensor 9 is used to monitor the temperature and humidity changes inside the box body 1.

[0068] In this embodiment, the temperature and humidity sensor 9 can send the monitored temperature and humidity values ​​inside the box 1 to the controller 4 in real time through the bus, and the controller 4 then uploads the corresponding data to the host, thereby realizing real-time acquisition of the temperature and humidity inside the box 1; and since the temperature and humidity sensor 9 is connected to the controller 4 through the bus, the temperature and humidity sensor 9 can also be connected to external devices using a watertight connector 5, avoiding the need for the temperature and humidity sensor 9 to be routed separately and the need to set up a separate external connector on the box 1, resulting in an increase in the number of external connectors of the entire device, affecting the sealing and waterproof properties of the device.

[0069] Furthermore, considering that the device may need to stop the transmission of oil in some cases when it is normally performing the function of transmitting oil, that is, to stop the flow of oil in the oil circuit block 2, this embodiment also involves the following designs:

[0070] like Figure 3 As shown, the underwater integrated bus-controlled proportional drive valve box also includes a hydraulic lock 10, wherein: the hydraulic lock 10 is arranged on the oil circuit block 2 and is connected to the oil circuit block 2, and the hydraulic lock 10 is connected to the controller 4 through a bus.

[0071] In this embodiment, the hydraulic lock 10 is used to lock the circuit for transmitting oil in the oil circuit block 2, so that the flow of oil in the oil circuit block 2 stops. It should be noted that the docking position between the hydraulic lock 10 and the oil circuit block 2 is sealed to prevent oil leakage.

[0072] In this embodiment, for the sake of device assembly, the box 1 needs to be disassembled or assembled in a suitable form. Therefore, this embodiment also involves the following designs:

[0073] like Figure 4 and Figure 5 As shown, the box body 1 includes an upper box body 11 and a lower box body 12, wherein: the upper box body 11 is arranged at the upper end of the lower box body 12, the upper box body 11 and the lower box body 12 are connected to each other and form an accommodating space inside, and the oil circuit block 2, multiple proportional valves 3 and controller 4 are all located in the accommodating space.

[0074] The lower end surface of the upper box 11 is located at the first docking platform 111, and the upper end surface of the lower box 12 is located at the second docking platform 121. When the upper box 11 and the lower box 12 are connected, the lower end surface of the first docking platform 111 and the upper end surface of the second docking platform 121 are in contact and fixed. The docking position between the upper box 11 and the lower box 12 is sealed and fixed by a sealing ring.

[0075] In this embodiment, the sealing ring can be sealed in the form of static sealing. In this embodiment, an O-ring can be selected. Considering that underwater operations need to ensure the corrosion resistance of the sealing ring, the sealing ring in this embodiment can be made of nitrile rubber material.

[0076] Furthermore, in order to more reasonably plan the layout of the components in the box 1, this embodiment also involves the following designs:

[0077] like Figure 4 and Figure 5 As shown, the underwater integrated bus-controlled proportional drive valve box also includes a bracket 14, wherein: the bracket 14 includes a plurality of supporting legs 141 and a supporting platform 142, and the supporting platform 142 is arranged on the upper ends of the plurality of supporting legs 141; the plurality of supporting legs 141 are arranged on the inner lower end surface of the box body 1, and the plurality of supporting legs 141 are distributed on both sides of the oil circuit block 2, the supporting platform 142 is located above the plurality of proportional valves 3, and the controller 4 is arranged on the upper end surface of the supporting platform 142.

[0078] like Figure 6 and Figure 7 As shown, it is a schematic diagram of the driving valve of the proportional driving valve box controlled by the underwater integrated bus. The controller 4 obtains the signals collected by each monitoring device, such as 4mA-20mA current, 0V-5V voltage and resistance, so as to monitor the pressure and flow in the box 1. The controller 4 drives each proportional solenoid valve 31 through the bus to adjust the flow of the oil. Two DC24V power supplies plus two shielded twisted pair communication cables can be used to connect with external devices, thereby reducing external interference. On this basis, a watertight connector 5 is used for quick plugging.

[0079] In this embodiment, the underwater integrated bus-controlled proportional drive valve box functions as a standalone device unit. Internally, it can be directly controlled by input and output signals from a controller 4, with external wiring consisting of power and communication cables. The operation of the device's solenoid valves is controlled by an external host, reducing the number of components. Control logic and functions are implemented through internal software editing, and specific control methods can be referenced in the prior art.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
