Description

Technical Field

[0001] The invention relates to the technical field of hydraulic systems, and in particular to an explosion-proof pipe device and a hydraulic system. Background Art

[0002] The current hydraulic system uses pressure detection to determine whether the hydraulic system is leaking. When the hydraulic system is working normally, the working pressure is generally within a certain range. When a leak occurs in the system, the pressure sensor detects that the working pressure is lower than the normal working set value and then issues an alarm to the hydraulic system.

[0003] It is not accurate to use pressure detection alone to determine whether there is a fluid leak in the hydraulic system. The hydraulic system itself has many components. When the pressure is low, it may be that the main pump is damaged or the pressure valve and other components are faulty, and there is no flow through the system. Therefore, there are many false alarms or inaccurate alarms in the existing hydraulic system. Summary of the invention

[0035] See also Figure 1 and Figure 2 An explosion-proof pipe device 100 provided in an embodiment of the present invention includes a flow detection component 1, a pressure detection component 2, a shell 3, a control component, an indication component 4 and a control cabinet 5.

[0036] The flow detection component 1 and the pressure detection component 2 are respectively arranged on the shell 3 and are both electrically connected to the control component. The shell 3 is used to be connected to the pipeline of the hydraulic system; the indication component 4 is arranged on the outer surface of the control cabinet 5, and the control component is arranged inside the control cabinet 5 and is used to be electrically connected to the control system of the hydraulic system.

[0037] The control component is used to receive the flow parameters of the pipeline detected by the flow detection component 1 and the pressure parameters of the pipeline detected by the pressure detection component 2, and when it is determined that the flow parameters and the pressure parameters reach the set values, control the indication component 4 to issue an alarm indication and send an alarm signal to the control system.

[0038] In this embodiment, the explosion-proof pipe device 100 of the present invention is applied to various hydraulic transmission systems, and can be used to monitor the flow and pressure of the hydraulic system in real time to detect whether the hydraulic system has a pipe explosion. If an abnormal situation such as a pipe explosion is detected, an alarm is actively issued and an alarm signal is sent to the hydraulic system, so that the control system of the hydraulic system issues an alarm or shuts down the hydraulic system to protect the safe operation of the hydraulic system.

[0039] Specifically, the housing 3 of the explosion-proof pipe device 100 is connected to the pipeline of the hydraulic system. The flow detection component 1 is arranged on the housing 3, and is used to detect the real-time flow of the liquid in the pipeline, and then send the flow parameter to the control component. The pressure detection component 2 is arranged on the housing 3, and is used to detect the real-time pressure of the liquid in the pipeline, and then send the pressure parameter to the control component.

[0040] The indicating component 4 is arranged on the outer surface of the control cabinet 5, so as to facilitate the operator to check the current operating status of the hydraulic system, such as the current flow parameter and the current pressure parameter.

[0041] The control component is arranged inside the control cabinet 5, and can provide waterproof and dustproof protection for the control component. The control component can receive the flow parameters of the pipeline sent by the flow detection component 1 and the pressure parameters of the pipeline sent by the pressure detection component 2. The control component is the core control component of the entire device, which is responsible for receiving, processing and displaying the flow and pressure signals, and making judgments and controls according to the set parameters. By setting the detection parameters of the control component, the flow and pressure real-time parameters when the pipe bursts can be set. When the control component detects that the flow parameters of the flow detection component 1 and the pressure parameters of the pressure detection component 2 do not reach the set values, it is judged that the pipe has not burst. When the control component detects that the flow parameters of the flow detection component 1 and the pressure parameters of the pressure detection component 2 reach the set values, it is judged that the pipe has burst, and the alarm will be turned on, and the signal will be transmitted to the indication component 4, and the indication component 4 indicates the alarm information, and at the same time, the alarm signal is connected to the control system of the original hydraulic system to realize the alarm or shutdown of the hydraulic system pipe burst, so as to protect the hydraulic system in time and avoid greater losses caused by the pipe burst.

[0042] Compared with the prior art, the explosion-proof pipe device 100 of the embodiment of the present invention is used in the hydraulic system, and the flow rate and pressure of the hydraulic system pipeline liquid are detected by the flow rate detection component 1 and the pressure detection component 2, so as to judge whether there is leakage through the flow rate and pressure. When the flow rate parameter and the pressure parameter reach the set value, the leakage is judged, and then an alarm is issued, and the detection and alarm are more accurate; at the same time, more accurate alarms improve the overall safety and the waste of materials caused by oil leakage. In addition, the added flow rate and pressure detection greatly reduces the maintenance time when the hydraulic system fails, and reduces labor.

[0043] In a specific embodiment, the flow detection component 1 includes a flow sensor.

[0044] In this embodiment, the flow sensor is a device for measuring fluid flow, which can convert the fluid flow signal into an electrical signal. Common flow sensors include electromagnetic, ultrasonic, vortex and other types, and their measurement principles are based on electromagnetic induction, acoustic principles, fluid mechanics principles, etc.

[0045] In a specific embodiment, the pressure detection component 2 includes a pressure sensor.

According to the test pressure type, it can be divided into a gauge pressure sensor, a differential pressure sensor, an absolute pressure sensor, etc., and is used in the explosion-proof pipe device 100 to measure the pressure of the hydraulic system pipeline liquid.

[0047] In a specific embodiment, there are plural flow sensors and plural pressure sensors.

[0048] In this embodiment, the flow sensor and the pressure sensor are redundantly configured. When one of the sensors fails, other flow sensors of the same type can still work normally, thereby ensuring the continuous monitoring capability of the explosion-proof pipe device 100 and avoiding monitoring interruption and safety hazards caused by sensor failure.

[0059] In this embodiment, when the control component receives the pipeline flow parameters sent by the flow detection component 1 and the pipeline pressure parameters sent by the pressure detection component 2, the control component controls the instrument component 7 to display the real-time flow parameters and real-time pressure parameters of the current hydraulic system in real time.

[0060] In one embodiment, the instrument assembly 7 may be a secondary control instrument.

[0061] Furthermore, in other embodiments, the display screen of the secondary control instrument can be upgraded to a touch screen to provide a more intuitive and convenient operation interface. The touch screen can be used to conveniently perform operations such as parameter setting, data query, and alarm record viewing, and can also display richer graphical information, such as flow and pressure curves, so that operators can more intuitively understand the operating status of the hydraulic system.
