Description

Technical Field

[0001] This utility model relates to a bidirectional linkage composite oil source, belonging to the field of hydraulic oil source supply technology. Background Technology

[0002] As the core supply equipment of the oil system in mechanical power systems, the oil source has been widely used in various automation fields. Currently, in shipyard applications, the side thrusters and anchor winches of ships both require the use of corresponding oil source control. In other words, the traditional single oil source cannot meet the work of two oil circuit systems at the same time. Setting up two independent oil source systems requires multiple oil tanks and corresponding sensing elements, which increases the actual configuration cost and is not conducive to lightweight configuration and cost reduction, resulting in low product market competitiveness. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bidirectional linkage composite oil source for multi-directional oil supply in a composite working oil circuit system. It can enable two or more working oil circuit systems to operate simultaneously using one oil source, thereby reducing configuration costs, simplifying control methods, and enhancing product market competitiveness.

[0004] To achieve the above objectives, this utility model employs the following technical solution: This utility model provides a bidirectional linkage composite oil source, including an oil tank. A first outlet and a second outlet are located at the bottom of the oil tank. A first control valve assembly is also provided on the oil tank. The first control valve assembly has a first inlet and a second inlet. A first working oil port is connected to the first inlet, and a second working oil port is also connected to the second inlet. The first control valve assembly also has a first check valve for controlling the opening and closing of the first working oil port and a second check valve for controlling the opening and closing of the second working oil port. The first control valve assembly also has two return oil channels, which are connected to the oil tank via return oil filters.

[0005] Specifically, the two return oil channels of the first control valve group are merged to form the main return oil channel, which is connected to the oil tank through the return oil filter.

[0006] Specifically, electromagnetic relief valves are connected to both the first working oil port and the second working oil cavity located on and inside the first control valve group.

[0007] Specifically, a second control valve group is connected to the first working oil port and / or the second working oil port of the oil tank via a connecting pipe. The second control valve group is equipped with at least an inlet / outlet oil channel and a return oil channel.

[0008] Specifically, a high-pressure filter is installed on the second control valve assembly at the pipe section located in the oil inlet / outlet channel.

[0009] Specifically, a positioning plate is installed on the oil tank, and the connecting pipes connected to the first working oil port and the second working oil port, as well as the return oil pipe of the corresponding oil circuit system, are all set on the positioning plate.

[0010] Specifically, the oil tank is also equipped with a thermometer, a level gauge, a level relay, and an air filter.

[0011] Specifically, an L-shaped pipe connected to the inside of the oil tank is installed at the bottom of the exterior of the oil tank. The L-shaped pipe extends towards the top of the oil tank, and the highest point inside the L-shaped pipe is higher than the liquid level of the oil medium inside the oil tank. One side of the L-shaped pipe is connected to an air pipe via a solenoid valve. The upper end of the L-shaped pipe is set as an opening, and an air filter element is installed at the opening. A viewing window for observing the liquid level in the pipe is provided on the side of the L-shaped pipe.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention features a specially designed first control valve group that allows for the simultaneous existence of two oil supply systems. The one-way valve configuration enables it to operate independently or simultaneously, making it suitable for various working oil circuit environments that require coordination. The simple structure eliminates the need for multiple oil sources, effectively reducing equipment configuration costs and enhancing the equipment's versatility. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0015] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0017] This utility model provides a bidirectional linkage composite oil source for multidirectional oil supply to a composite working oil circuit system. It can simultaneously enable two or more working oil circuit systems to operate using a single oil source, thereby reducing configuration costs, simplifying control methods, and enhancing product market competitiveness. To achieve the structural functions of the device, it includes an oil tank 1 for storing oil medium to be supplied to the system. A first outlet 2 and a second outlet 3 (not shown in the figure) are located at the bottom of the oil tank 1 and are respectively connected to corresponding oil pumps. The oil pumps provide oil supply power to the system. To achieve the configuration of coordinated operation of the composite oil circuit, a first control valve group 4 is also provided on the oil tank 1. Specifically, the first control valve group 4 has a first oil inlet. Port 5 and the second inlet 6 are used to receive hydraulic oil from two oil pumps. To supply these two hydraulic oil lines to different working oil circuit systems, the first control valve group 4 is equipped with a first working oil port connected to the first inlet 5, and a second working oil port connected to the second inlet 6. To facilitate individual or coordinated control of the two oil systems, the first control valve group 4 is equipped with a first check valve 9 for controlling the opening and closing of the first working oil port and a second check valve 8 for controlling the opening and closing of the second working oil port. To ensure that the oil medium from both working oil circuits can flow back to the oil tank 1 normally, the first control valve group 4 is also equipped with two return oil channels, which are connected to the oil tank 1 through a return oil filter 10. This method, through a special design of the first control valve group 4, enables it to simultaneously operate two working oil systems. It allows for the simultaneous supply of oil to different working oil circuits using a single oil source, effectively utilizing hydraulic oil while reducing configuration costs, thereby enhancing product competitiveness. In some implementations, if there are two return oil channels connected to the oil tank 1 respectively, then two return oil filters 10 need to be configured. In order to save equipment consumables, the two return oil channels of the first control valve group 4 can be combined to form the main return oil channel. In this case, the main return oil channel can be connected to the oil tank 1 through the return oil filter 10. It is preferable to configure separate check valves on the two return oil pipelines to avoid one return oil channel supplying oil to the other return oil channel, which would prevent the return oil from smoothly entering the oil tank 1.

[0018] This utility model provides a bidirectional linkage composite oil source. To avoid excessive pressure in the oil circuit working system, two electromagnetic relief valves 19 are installed on the first control valve group 4. They are respectively connected to the first working oil port and the second working oil port inside the first control valve group 4. By configuring the electromagnetic relief valves 19, the system pressure can be effectively controlled and low-pressure operation can be maintained when not in operation.

[0019] This utility model provides a bidirectional linkage composite oil source. In some embodiments, considering that the actual working positions of different oil circuit systems may be far from the oil tank 1, resulting in the first control valve group 4 having a long control distance and not being able to act on the working position and make adjustments in time, a second control valve group 11 is provided here through a connecting pipe on the first working oil port and / or the second working oil port of the oil tank 1, as shown in the figure. Figure 4 As shown, the second control valve group 11 is specifically equipped with at least an inlet / outlet oil channel and a return oil channel. The inlet / outlet oil channel is used to receive hydraulic oil from the first control valve group 4 and supply it to the oil circuit at the working position. In the shipyard working system, when the oil source is far away from the anchor winch and the side thruster, the valve block size can be effectively saved, and remote control can be realized.

[0020] This utility model provides a bidirectional linkage composite oil source. In order to ensure that the oil pressure is kept low when supplying oil to the working system, a high-pressure filter 12 is installed on the second control valve group 11 and at the pipe section of the oil inlet and outlet channel. The high-pressure filter 12 is used to filter out tiny impurities and achieve fine filtration by utilizing the pressure difference of the oil pressure.

[0021] This utility model provides a bidirectional linkage composite oil source. To prevent the working oil circuits of the two systems from tangling and knotting on the oil tank 1, a positioning plate 7 is installed on the oil tank 1. The connecting pipes connecting the first and second working oil ports, as well as the return oil pipes of the corresponding oil circuit systems, are all positioned on the positioning plate 7. (Refer to...) Figure 2 The connection method shown can effectively avoid complex connections between different pipelines, thereby facilitating personnel organization and reducing the probability of human error.

[0022] This utility model provides a bidirectional linkage composite oil source. In order to improve the function of the oil tank 1 and ensure a high-quality supply of oil, the oil tank 1 is also equipped with a thermometer 13 for detecting the temperature of the oil medium, a level gauge 16 to prevent insufficient oil medium level from causing dry suction and damage, a level relay 14 to stop the oil supply in time when the oil medium level is insufficient to avoid system failure, and an air filter 15 to filter impurities contained in the gas when the gas enters and exits the oil tank 1.

[0023] This utility model provides a bidirectional linkage composite oil source. The temperature of the oil medium directly affects its viscosity. If the viscosity is too low, it will increase the system load; if the viscosity is too high, it may lead to lubrication failure. To facilitate manual observation of the oil viscosity and to confirm whether the oil source is aging or can work efficiently, the following can be referred to... Figure 1As shown, an L-shaped pipe 17, which communicates with the interior of the oil tank 1, is installed at the bottom of the exterior of the oil tank 1. Specifically, the L-shaped pipe 17 extends upwards towards the oil tank 1, and the highest point inside the L-shaped pipe 17 is higher than the liquid level of the oil medium inside the oil tank 1. The upper end of the L-shaped pipe 17 is set as an opening, and an air filter element is installed at this opening. It and the oil tank 1 form a communicating vessel, so that the oil medium inside the oil tank 1 is at the same height as the oil medium inside the oil tank 1. At this time, an air pipe 18 is connected to one side of the L-shaped pipe 17 through a solenoid valve. The air pipe 18 is used to supply air into the L-shaped pipe 17. Small air bubbles can cause significant discrepancies between the oil level in the L-shaped tube 17 and the oil level in the tank 1 when the oil viscosity is too high. Conversely, at lower viscosity, the bubbles dissipate quickly, resulting in a smaller level rise deviation. Therefore, viscosity can be easily determined by venting. A viewing window is provided on the side of the L-shaped tube 17 for observing the liquid level during venting (the same viewing window design can be used on the oil tank 1 to allow for comparison). To ensure reliable data transmission, a mesh structure (not shown in the figure) can be installed at the outlet of the venting tube 18 to separate the gas into small air bubbles. The venting tube 18 and the L-shaped tube 17 can be connected by a check valve to prevent liquid from flowing into the venting tube 18.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
