Description

Technical Field

[0001] This utility model relates to the field of oil drilling and production technology and special equipment for increasing production, specifically an intelligent and safe hydraulic oil tank. Background Technology

[0002] As the "heart" of a hydraulic system, the hydraulic oil tank's importance extends far beyond that of a simple oil storage container. It plays an indispensable role in ensuring the normal operation of the hydraulic system and extending the service life of hydraulic components. However, currently available traditional hydraulic oil tanks are only equipped with basic components such as level gauges, air filters, suction filters, return filters, and drain valves. They almost entirely lack devices for detecting oil quality-related factors such as oil temperature, liquid contaminants, and solid contaminants. Maintenance is primarily performed manually on a regular basis, resulting in extremely low accuracy. Furthermore, because maintenance personnel often simply add oil, they neglect to detect contaminants and assess oil quality. This leads to the accumulation of contaminants within the hydraulic tank and system over time, causing damage to hydraulic components, frequent system failures, significantly reducing the system's lifespan, and increasing maintenance costs. Therefore, a smart and safe hydraulic oil tank needs to be designed to address these and other potential problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an intelligent and safe hydraulic oil tank, which solves the problem of excessive contaminants in the hydraulic oil causing damage to the entire hydraulic system.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an intelligent safety hydraulic oil tank, including an oil tank body and a controller. The upper part of the oil tank body is provided with a flame sensor, a return oil filter and an automatic fire extinguishing device. The side of the oil tank body is provided with a suction oil filter and a suction limit switch. The lower part of the oil tank body is provided with a temperature sensor. The rear of the oil tank body is provided with an oil level sensor, an oil water content detection sensor, a solid contaminant detection sensor and an electric pump. The controller is connected to an electronic differential pressure transmitter alarm device, a fire extinguishing alarm device, a temperature signal device, an oil level alarm device and an oil water content alarm device.

[0005] As an optimization, the oil suction limit switch is connected to a matching oil suction ball valve handle and a limit switch.

[0006] As an optimization, the electric pump receives an electrical signal transmitted from the level sensor.

[0007] As an optimization, the fuel tank body is made of stainless steel.

[0008] As an optimization, both the suction filter and the return filter are equipped with electronic differential pressure transmitters.

[0009] As an optimization, a powerful magnet is installed inside the fuel tank body.

[0010] The beneficial effects of this utility model are as follows: This utility model provides an intelligent and safe hydraulic oil tank, equipped with an electric pump, a suction limit switch, an oil level sensor, a temperature sensor, an oil cleanliness sensor, an online water content detection sensor, and a flame sensor. Both the suction filter and the return filter are equipped with electronic differential pressure transmitters. A strong magnet can attract fine iron filings in the oil; the suction limit switch determines whether the suction ball valve is open or closed; various performance parameters of the oil in the hydraulic oil tank can be displayed in real-time on the equipment control panel via sensors; and the flame sensor is linked to the vehicle's fire extinguishing system. This hydraulic oil tank provides comprehensive monitoring of the hydraulic oil status, preventing damage to the entire hydraulic system caused by excessive contaminants in the hydraulic oil. It also avoids other impacts caused by manual operation, thereby extending the service life of the hydraulic system, reducing maintenance costs, and improving equipment efficiency.

[0016] like Figure 1-2 As shown, an intelligent safety hydraulic oil tank includes an oil tank body and a controller. The upper part of the oil tank body is equipped with a flame sensor 3, a return oil filter 4, and an automatic fire extinguishing device. One side of the oil tank body is equipped with a suction filter 1 and a suction limit switch 2. The lower part of the oil tank body is equipped with a temperature sensor 6. The rear of the oil tank body is equipped with an oil level sensor 7, an oil water content detection sensor 8, a solid contaminant detection sensor 9, and an electric pump 10. The controller is connected to an electronic differential pressure alarm device, a fire extinguishing alarm device, a temperature signal device, an oil level alarm device, and an oil water content alarm device. The suction limit switch 2 is connected to a suction ball valve handle and a limit switch that cooperate with each other. The electric pump 10 receives electrical signals transmitted from the level sensor. The oil tank body is made of stainless steel. Both the suction filter 1 and the return oil filter 4 are equipped with electronic differential pressure transmitters. A powerful magnet is installed inside the oil tank body.

[0017] The suction filter 1 and the return filter 4 are equipped with an electronic differential pressure transmitter alarm device: when the filter element is blocked by contaminants or the system oil temperature is too low, the flow pulsation or other factors cause the pressure difference inside the filter to be too large, the electronic transmitter will generate an electrical signal and transmit it to the equipment control panel to trigger the alarm. Oil suction limit switch 2: The state of the ball valve is determined by whether the oil suction ball valve handle is in contact with the contact point: When the ball valve handle is in contact with the limit switch contact point, the moving contact and stationary contact inside the switch are closed, the contacts in the circuit are closed, and the change of the contacts in the circuit generates a switching signal, which is transmitted to the equipment control panel to display the ball valve switching state. If the ball valve is in the closed state, the engine will not be allowed to start. Flame sensor 3: Its main working principle is to identify and monitor specific wavelengths generated by flames. When the thresholds of both infrared (IR) and ultraviolet (UV) channels are detected simultaneously, an alarm is triggered. After detecting a fire, it outputs a current signal to the equipment controller, and the fire extinguishing system is activated manually or by a preset program in the controller. Automatic fire extinguishing device 5: After the flame sensor 3 triggers the alarm, the automatic fire extinguishing device 5 receives the sensor signal and drives the valve core inside the fire extinguishing device to work and release the fire extinguishing agent; at the same time, in an emergency, the fire extinguishing can be forced through the physical button. Temperature sensor 6: Achieves thermal equilibrium through conduction, thereby generating a temperature signal, which is transmitted to the equipment control panel via circuitry to monitor the hydraulic oil temperature in real time, preventing excessively high oil temperature from accelerating oil deterioration and causing a decrease in system efficiency; Oil level sensor 7: It measures the oil level by utilizing the difference in dielectric constant between oil and air, and outputs a current signal to the control module. The oil level changes are displayed in real time on the equipment control panel. At the same time, an alarm threshold can be set, and an alarm will be triggered when the value is lower than the set alarm threshold. Oil water content detection sensor 8: Its main principle is to output an electrical frequency signal based on the difference in capacitance value between hydraulic oil and water due to the difference in dielectric constant. The magnitude of the current in the detection circuit can reflect the dielectric constant in the hydraulic oil, thereby calculating the water content in the hydraulic oil and feeding it back to the control module. When the water content exceeds the alarm threshold, an alarm prompt will be triggered on the equipment control panel. Solid pollutant detection sensor 9: Its main principle is to monitor and calculate the pollution level by utilizing the absorption and blocking of laser beams by solid particles. When hydraulic oil flows through the sensor's detection area, it absorbs some light. At this time, the sensor calculates the concentration of pollutants by the light transmittance and feeds it back to the control module. When the concentration exceeds the alarm threshold, an alarm will be triggered on the equipment control panel. Electric pump 10: The electric pump can receive electrical signals transmitted from the liquid level sensor. When the liquid level sensor issues a low-level alarm, the control module of the electric pump will send a signal, and the electric pump will start working to automatically replenish the hydraulic oil tank to prevent the hydraulic pump from sucking in air due to the low oil level. At the same time, the operator can also manually start replenishing oil according to the liquid level.

[0018] A smart safety hydraulic oil tank monitors the hydraulic oil status in real time, provides early warning of potential hydraulic oil faults, enables predictive maintenance, extends the service life of the hydraulic oil, reduces cost losses caused by hydraulic issues, and improves equipment efficiency.
