Description

Technical Field

[0001] This utility model relates to the field of water conservancy tools technology, and in particular discloses an emergency actuator for water utilization. Background Technology

[0002] Currently, emergency actuators in water conservancy projects mostly use electric or pneumatic drives, which pose a risk of power interruption in the event of a sudden power outage or air supply failure. Furthermore, traditional mechanical structures suffer from complex operation and inconvenient maintenance. For example, existing devices lack manual emergency operation functions, and the hydraulic system does not integrate pressure monitoring and automatic pressure relief devices, resulting in a high risk of overload. Exposed transmission components are susceptible to contamination and have insufficient sealing, posing a risk of oil leakage. The oil tank design is not conducive to visualization and liquid level observation, and lacks temperature monitoring, affecting system stability. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a water utilization emergency actuator.

[0004] To achieve the above objectives, this utility model provides a water utilization emergency actuator, comprising an oil tank for storing hydraulic oil, a hydraulic motor installed inside the oil tank, a valve block assembly, and a clutch disposed outside the oil tank. The valve block assembly includes a reversing valve. The clutch is connected to the output shaft of the hydraulic motor, and the end of the clutch away from the hydraulic motor is connected to external equipment. The hydraulic motor includes an oil inlet and an oil outlet. The oil inlet communicates with the oil tank, and the oil outlet is connected to the reversing valve. The hydraulic pump delivers hydraulic oil to the oil inlet of the hydraulic motor to drive the hydraulic motor to operate. The hydraulic oil returns to the oil tank from the oil outlet of the hydraulic motor through the reversing valve, causing the hydraulic motor to stop operating. The clutch is used to disconnect the power transmission between the hydraulic motor and the external equipment.

[0005] By integrating key components such as the oil tank, hydraulic motor, valve block assembly, and clutch, the hydraulic system achieves compact and efficient operation. The hydraulic pump draws hydraulic oil from the tank, controls the flow of the hydraulic oil through a directional valve, and drives the hydraulic motor. When it is necessary to stop the hydraulic motor, the directional valve guides the hydraulic oil back to the tank. The clutch is used to disconnect the power transmission between the hydraulic motor and external equipment when necessary, ensuring the system's flexibility and safety. This design not only improves the actuator's response speed and control accuracy but also enhances the system's reliability and maintainability.

[0006] The outer side of the oil tank is detachably equipped with a protective cover for covering and protecting the clutch. The protective cover includes a first annular cover and a second annular cover that covers the first annular cover. One end of the first annular cover is hinged to one end of the second annular cover, and the other end of the first annular cover is locked to the other end of the second annular cover via a locking device.

[0007] The protective cover design of the clutch provides effective protection for the connection between the clutch and external equipment, preventing the entry of external debris or accidental damage, while also facilitating maintenance and inspection. The protective cover consists of a first annular cover and a second annular cover, hinged at one end for easy opening and closing; the other end is tightly connected by a locking device to ensure the cover's stability and sealing. This detachable design allows for easy opening of the protective cover when clutch maintenance or inspection is needed, and quick restoration to the protected state after the operation is complete, improving the equipment's practicality and safety.

[0008] A manual crank is provided on the drive shaft of the clutch outside the oil tank. A fixed cylinder is fixed on the outside of the oil tank. The clutch is slidably disposed in the fixed cylinder. One end of the manual crank is rotatably disposed on the oil tank. The middle part of the manual crank acts on the clutch. The clutch engages or disengages with the main shaft of the hydraulic motor. The other end of the manual crank is provided with a grip ball for easy holding.

[0009] The manual crank has a ring portion and a rod portion disposed on the ring portion. The ring portion is sleeved on the outside of the clutch and located inside the fixed cylinder. The lower end of the ring portion is rotatably mounted on the oil tank. The rod portion is disposed on the upper end of the ring portion. The fixed cylinder has a sliding hole for accommodating the rod portion. A grip ball is disposed on the end of the rod portion away from the ring portion.

[0010] A manual crank is installed on the clutch drive shaft. When manual control of clutch engagement or disengagement is required, the operator can directly crank the crank, which in turn drives the clutch via the drive shaft. This design ensures that the equipment can still be operated manually in the event of a power system failure or automatic control system malfunction, improving the equipment's reliability and emergency response capability.

[0011] The valve block assembly also includes an overflow valve and a pressure sensor. When the pressure sensor detects that the pressure exceeds a predetermined value, the overflow valve opens to release pressure.

[0012] The valve block assembly integrates a pressure sensor to monitor pressure changes in the hydraulic system in real time. When the pressure sensor detects that the system pressure exceeds the preset safe range, it immediately triggers the relief valve to open, allowing some hydraulic oil to flow back to the oil tank through the relief valve, thereby reducing the system pressure to a safe level. This design not only improves the stability and safety of the hydraulic system but also extends the service life of system components and reduces failures and maintenance costs caused by excessive pressure.

[0013] The connection between the hydraulic motor and the clutch is equipped with a seal.

[0014] Multiple nitrile rubber O-rings and polytetrafluoroethylene rotary shaft lip seals are added at the connection between the hydraulic motor and the clutch to form a combined sealing structure: this design ensures that the hydraulic oil leakage is ≤0.1mL / h, while preventing external moisture intrusion.

[0015] High-quality seals are installed at the interface between the hydraulic motor and the clutch. These seals fit tightly against the surface of the connection, forming an effective sealing barrier to prevent hydraulic oil from leaking out. This design not only improves the efficiency of the hydraulic system and reduces hydraulic oil loss, but also avoids environmental pollution and equipment damage caused by hydraulic oil leakage, thus ensuring the long-term reliable operation of the hydraulic system.

[0016] The side of the oil tank also has a receiving cavity and an opening and closing door that covers the outside of the receiving cavity. The valve block assembly is housed in the receiving cavity. The opening and closing door is installed on the oil tank via a hinge structure. A handle for gripping is provided on the outside of the opening and closing door.

[0017] The actuator also includes multiple sets of temperature sensors.

[0018] Multiple temperature sensors are installed on the actuator. These sensors accurately detect temperature changes in the hydraulic oil within the tank and transmit the temperature signals to the control system in real time. By monitoring the data from the temperature sensors, operators can promptly understand the hydraulic oil's temperature status, preventing system performance degradation or component damage caused by excessively high or low oil temperatures. This design not only improves the stability and reliability of the hydraulic system but also helps extend the lifespan of system components, reducing maintenance costs and downtime.

[0019] The bottom of the fuel tank is equipped with a quick-release port, and a rupture disc is installed at the port.

[0020] A quick-release port is installed at the bottom of the oil tank, connecting to the inside of the tank for rapid pressure release in emergencies. A rupture disc installed at the port is a specially designed weak point that automatically ruptures when the system pressure exceeds a set threshold, allowing hydraulic oil to drain rapidly, reducing system pressure and preventing the tank from rupturing or exploding due to overpressure. This design not only improves the safety of the hydraulic system but also reduces the risk of equipment damage and personal injury caused by overpressure accidents.

[0021] The fuel tank has viewing windows on both sides and viewing covers on the viewing windows.

[0022] The aforementioned design, featuring viewing windows on both sides of the oil tank and corresponding cover plates, facilitates visibility and maintenance of the tank's interior, ensuring the cleanliness and long-term stable operation of the hydraulic system. The viewing windows on both side walls are large enough to allow operators easy access for inspection and visualization. Cover plates are fitted to these windows, normally closed to prevent dust and debris from entering the tank. When inspection or maintenance is required, simply opening the cover plates provides easy access to the tank's interior. This design not only improves maintenance efficiency but also extends the lifespan of the hydraulic system, reducing system failures and repair costs caused by the accumulation of dirt inside the tank.

[0023] The actuator also includes a level gauge located on the outside of the oil tank.

[0024] The design of the level gauge aims to monitor the hydraulic oil level in the tank in real time, ensuring the normal operation of the hydraulic system and preventing malfunctions caused by abnormal oil levels. A level gauge is installed on the outside of the tank, connected to the inside of the tank via a transparent tube or electronic sensor, accurately displaying the hydraulic oil level. Operators can observe the level gauge to monitor the hydraulic oil level in the tank at any time and replenish the oil in a timely manner to maintain the system operating within the normal oil level range. This design not only improves the reliability and stability of the hydraulic system but also effectively avoids system performance degradation or component damage caused by insufficient or excessive hydraulic oil, reducing maintenance costs and downtime.

[0025] The actuator also includes an oil hole located at the top of the oil tank and an oil seal head for opening and closing the oil hole.

[0026] Oil seals are used to open and close oil ports, ensuring the oil tank remains sealed when oil is not being added or drained. Opening and closing the oil seals effectively prevents dust, moisture, or other contaminants from entering the oil tank, maintaining the cleanliness of the hydraulic oil.

[0027] The beneficial effects of this utility model are as follows: By integrating key components such as the oil tank, hydraulic motor, valve block assembly, and clutch, and incorporating features such as a protective cover for the clutch, a manual crank for emergency operation, an overflow valve and pressure sensor to regulate system pressure, seals to prevent hydraulic oil leakage, a accommodating cavity to house the valve block assembly, a temperature sensor to monitor oil temperature, a quick-release interface and rupture disc for safety, a viewing window and cover for convenient maintenance, a level gauge for real-time level monitoring, and an oil hole and oil seal at the top of the oil tank to maintain its seal, this utility model achieves a compact, efficient, flexible, and safe hydraulic system operation. The opening and closing function of the oil seal effectively prevents contaminants from entering the oil tank, keeping the hydraulic oil clean, improving the reliability, stability, and maintainability of the hydraulic system, reducing failure and repair costs, and extending the system's service life.
