[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The core of the utility model is to provide a hydraulic power system of a deep-sea operation type ROV and a deep-sea operation type ROV, which can reduce the floor space occupied by the hydraulic power system.

[0041] For a specific embodiment of the hydraulic power system of the deep-sea operation ROV provided by the utility model, please refer to Figures 1 to 3 The deep-sea operation ROV includes a frame 11, and a partition frame 111 is provided in the middle of the frame 11 to divide the space in the frame 11 into an upper space and a lower space.

[0042] The upper space is provided with an electric control device 2, an electromagnetic reversing valve 4, and an oil tank 10, and the lower space is provided with a hydraulic pump assembly 8.

[0043] like Figure 3As shown, the electromagnetic reversing valve 4 is connected to the oil tank 10 through the first pipeline assembly 7, and the hydraulic pump assembly 8 is connected to the first pipeline assembly 7. The first pipeline assembly 7 may specifically include an oil supply pipeline 71 and an oil return pipeline 72 respectively connected between the electromagnetic reversing valve 4 and the oil tank 10, and the oil return pipeline 72 is specifically a pressure relief manifold circuit. The electromagnetic reversing valve 4 is connected to the second pipeline assembly 3 for connecting the hydraulic gripper 1. The hydraulic gripper 1 has a gripper hydraulic cylinder mechanism, and the gripper hydraulic cylinder mechanism has a rod chamber and a rodless chamber. The second pipeline assembly 3 is connected to the gripper hydraulic cylinder mechanism, so that the rod chamber and the rodless chamber alternately fill and return liquid, driving the clamping jaws of the hydraulic gripper 1 to grasp or release. The second pipeline assembly 3 may specifically include two hydraulic hoses.

[0044] The electromagnetic reversing valve 4 is communicatively connected to the electronic control device 2, and the communication connection can be wired or wireless. The electromagnetic reversing valve 4 can perform reversing action under the electronic control of the electronic control device 2, so as to alternately feed and return liquid to the rod chamber and the rodless chamber. Specifically, the electronic control device 2 is provided with buttons, knobs and other structures to perform electronic control reversing control of the electromagnetic reversing valve 4, and the electronic control device 2 can also be remotely controlled by communicating with a remote control or other terminal device.

[0045] In this embodiment, a double-layer frame 11 is used to provide two layers of space for installing components in the hydraulic power system respectively, which can improve the structural compactness of the system and reduce the footprint. In addition, the electronic control device 2 that needs to be operated is located in the upper space, which can reduce the obstruction of other equipment and facilitate the user to perform operations such as switching of the electronically controlled electromagnetic reversing valve 4.

[0046] Among them, the electromagnetic reversing valve 4 also has an operating handle that can be manually controlled for reversing, specifically a manual electromagnetic reversing valve. At this time, when the electromagnetic reversing valve 4 controls the action of the hydraulic gripper 1, the reversing of the electromagnetic reversing valve 4 can be manually controlled, or the reversing of the electromagnetic reversing valve 4 can be electronically controlled by the electronic control device 2. The flexibility of the reversing control is relatively high, and through electronic control, the convenience and efficiency of reversing can be improved.

[0047] Among them, Figure 1 As shown, a hydraulic lock 32 is also provided on the second pipeline assembly 3, so that the hydraulic gripper 1 can maintain the state after being gripped, and can maintain the state after being released, thereby improving the reliability of the use of the hydraulic gripper 1.

[0048] Among them, for the specific structure of the rack 11, such as Figure 1 and Figure 2As shown, it is a carrier of the hydraulic power system, specifically including a top plate 112, a bottom plate 113 located below the top plate 112, and a plurality of connecting rods 114 fixedly connecting the top plate 112 and the bottom plate 113. For example, there are four connecting rods 114, and the top plate 112 and the bottom plate 113 are connected to form a rectangular body frame through the connecting rods 114. The partition frame 111 is fixed to each connecting rod 114 and is located between the top plate 112 and the bottom plate 113. The space between the partition frame 111 and the top plate 112 is an upper space, and the space between the partition frame 111 and the bottom plate 113 is a lower space.

[0049] Specifically, Figure 1 As shown, the edges of the partition frame 111 and the top plate 112 and the adjacent connecting rods 114 form a lateral opening 115, and the electronic control device 2 is arranged near at least one lateral opening 115, so as to facilitate the operation and maintenance of the electronic control device 2. There may be multiple lateral openings 115, and different parts of the electronic control device 2 may be near the same or different lateral openings 115. In addition, the oil tank 10 may also be arranged near the lateral opening 115 for assembly and maintenance. In addition, the oil tank 10 is refueled through the oil filling port 101 on the oil tank 10, and the oil is discharged through the oil discharge ball valve 102. The oil tank 10 is provided with an oil tank cleaning flange 104 for easy cleaning, and an oil tank inspection window 116 may be provided on the top plate 112 for easy inspection of the oil tank 10.

[0050] Specifically, the frame 11 is a skid frame, which can be divided from bottom to top into a skid structure (which can be set on the bottom plate 113), a frame structure, and a lifting structure (which can be the lifting ears 117 set on the four top corners of the top plate 112), which is formed by welding the channel steel skid and the square frame. Among them, the lifting ears 117 are used for lifting, and the bottom plate 113 can be provided with forklift holes.

[0051] To prevent impurities in the oil from affecting the operation of the equipment, Figure 3 As shown, an oil suction filter 711 is also provided on the oil supply line 71 at the suction port side of the hydraulic pump assembly 8, and the oil suction filter 711 is used to filter impurities in the oil tank 10 to effectively prevent damage to the seal of the hydraulic pump assembly 8. Among them, a pump inlet ball valve 712 can be provided on the oil supply line 71 between the hydraulic pump assembly 8 and the oil suction filter 711. In addition, an oil return filter 721 is also provided at the outlet of the oil return line 72, and the oil return filter 721 is used to filter impurities in the oil return line 72 to effectively prevent impurities from entering the oil tank 10.

[0052] To avoid hydraulic oil emulsification, Figure 3As shown, a first bypass pipeline 5 is further provided on the oil supply pipeline 71 between the outlet side of the hydraulic pump assembly 8 and the oil tank 10, a water removal filter 51 is provided on the first bypass pipeline 5, and an upstream stop valve 52 and a downstream stop valve 53 are respectively provided on the oil inlet side and the oil outlet side of the water removal filter 51 on the first bypass pipeline 5. The water removal filter 51 includes a main water removal filter 511 and a standby water removal filter 512 which are provided in parallel.

[0053] When in use, when the hydraulic gripper 1 is not in use, the upstream stop valve 52 and the downstream stop valve 53 can be opened, and the hydraulic oil in the oil tank 10 circulates through the first bypass line 5. The water removal filter 51 can absorb the water in the hydraulic oil, effectively preventing the hydraulic oil from emulsification and extending the service life of the hydraulic oil. When the hydraulic gripper 1 is in use, the upstream stop valve 52 and the downstream stop valve 53 can also be closed.

[0054] To prevent the oil from overheating, a cooling device 9 is also provided on the first pipeline assembly 7. The cooling device 9 is communicatively connected to the electronic control device 2. In addition, the cooling device 9 can be started and stopped by the electronic control device 2, which is convenient to operate. Figure 3 As shown, the cooling device 9 can be arranged on the oil return pipeline 72. Of course, in other embodiments, the cooling device 9 can also be arranged on the oil supply pipeline 71.

[0055] If the hydraulic oil is continuously circulating, the hydraulic oil will generate heat under high pressure and high speed friction. If the heat cannot be effectively dissipated, the oil temperature will continue to rise, resulting in high temperature failure of the hydraulic power system, damage to the pump valve seal, and leakage of the hydraulic power system. Overheating will also shorten the service life of the hydraulic oil. In this embodiment, by adding a cooling device 9 to cool the oil, the oil temperature can be prevented from overheating.

[0056] The cooling device 9 includes an air-cooled heat exchanger, which transfers the temperature of the hydraulic oil to the normal temperature air through the heat sink, removes the excess heat, and achieves cooling. In other embodiments, a water-cooled cooling device 9 may also be used.

[0057] In order to improve the safety of equipment operation, a temperature sensor 106 and a liquid level switch are also provided in the oil tank 10 .

[0058] Among them, Figure 3 As shown, the temperature sensor 106 is communicatively connected to the electronic control device 2, and the temperature sensor 106 is installed on the oil tank 10. The temperature sensor 106 can realize real-time monitoring of the oil temperature in the oil tank 10. When the oil temperature in the oil tank 10 detected by the temperature sensor 106 is greater than the preset alarm temperature, the alarm module of the electronic control device 2 alarms. Specifically, a temperature sound and light alarm can be set on the electronic control device 2. When the oil temperature is higher than the preset alarm temperature set in the electronic control device 2, an sound and light alarm is realized to prompt that the oil temperature is too high.

[0059] Among them, Figure 3 As shown, the liquid level switch is communicatively connected to the electronic control device 2, and the hydraulic pump assembly 8 is an electric hydraulic pump assembly communicatively connected to the electronic control device 2. The liquid level switch can be specifically a liquid level sensor 105 installed at a preset alarm liquid level of the oil tank 10. When the oil level in the oil tank 10 detected by the liquid level switch is lower than the preset alarm liquid level, the alarm module of the electronic control device 2 alarms and controls the electric hydraulic pump assembly to stop running.

[0060] Specifically, when the hydraulic oil leaks and is lost, the oil level continues to drop until the liquid level switch is triggered, which can be discovered in time. In addition, a liquid level sound and light alarm can be set on the electronic control device 2. When the liquid is lower than the preset alarm level set in the electronic control device 2, an sound and light alarm is implemented to prompt that the oil level is too low, and the electric hydraulic pump assembly stops working. In addition, a liquid level meter 103 can also be set in the oil tank 10. The liquid level meter 103 is connected to the electronic control device 2 in communication to understand the liquid level in the oil tank 10 in real time.

[0061] To facilitate the control of the hydraulic pump assembly 8, as Figures 1 to 3 As shown, the hydraulic pump assembly 8 includes a hydraulic pump 82 and an electric motor 81 connected to the hydraulic pump 82, and the electric motor 81 is connected to the hydraulic pump 82 through a coupling. In addition, the electronic control device 2 includes an electric hydraulic pump control box 22 and a hydraulic gripper control panel 21 that is communicatively connected to the electric hydraulic pump control box 22. The electric hydraulic pump control box 22 is communicatively connected to the electric motor 81.

[0062] During operation, the start button on the electric hydraulic pump control box 22 is manually pressed, the motor 81 starts to run, the motor 81 drives the hydraulic pump 82 to rotate through the coupling, the hydraulic pump 82 obtains kinetic energy, the hydraulic pump 82 inlet absorbs the hydraulic oil in the oil tank 10, and the hydraulic pump 82 outlet discharges high-pressure hydraulic pressure, the stop button is manually pressed, the motor 81 stops running, and the hydraulic pump 82 stops working at the same time.

[0063] In addition, the electric hydraulic pump control box 22 is connected to the motor 81 of the hydraulic pump assembly 8 via a power supply cable. The hydraulic gripper control panel 21 is communicatively connected to the electromagnetic reversing valve 4. Specifically, the hydraulic gripper control panel 21 is connected to the electromagnetic reversing valve 4 via a cable.

[0064] When in use, the gripping button on the hydraulic gripper control panel 21 is manually pressed, and the control signal output by the electronic control device 2 controls the electromagnetic reversing valve 4 to make the hydraulic gripper 1 grip; the release button on the hydraulic gripper control panel 21 is manually pressed, and the control signal output by the electronic control device 2 controls the electromagnetic reversing valve 4 to make the hydraulic gripper 1 loose. In addition, the hydraulic gripper 1 may have one or more, which may be uniformly controlled by the same gripping button and release button, or may be separately controlled by different gripping buttons and release buttons.

[0065] To facilitate the adjustment of operating fluid pressure, Figure 3 As shown, a second bypass pipeline 6 is further provided between the oil supply pipeline 71 and the oil outlet pipeline, on which a pressure gauge 61 and a pressure regulating valve 62 are provided. When working, the start button on the electric hydraulic pump control box 22 is manually pressed to control the hydraulic pump assembly 8 to start running and generate hydraulic pressure output. In this process, the pressure is displayed by the pressure gauge 61, and the manual pressure regulating valve is adjusted accordingly, for example, clockwise to increase the pump output pressure, and counterclockwise to reduce the pump output pressure, so that the pressure can be conveniently adjusted as needed.

[0066] In this embodiment, the frame 11 is divided into two layers, the upper layer is mainly electronically controlled and manually operated, which is convenient for the staff to operate from the upper space of the frame 11, and the lower space is mainly used to assemble the power output device and the cooling device 9.
