[0024] Embodiment

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a monitoring and alarm device for oil and petrochemical pumps, including a liquid inlet pipe 10, a fixing component 20 is arranged on the liquid inlet pipe 10, a monitoring component 30 is arranged on the top of the fixing component 20, and the fixing component 20 includes a pressing plate 21, a sealing gasket 22, a first connecting frame 23, a fixing shaft 24, a connecting plate 25, a second connecting frame 26, a fixing plate 27, a fixing bolt 28, a knob 29, a threaded column 210, a top plate 211 and a threaded sleeve 212;

[0026] The bottom of the pressing plate 21 is fixedly connected with a sealing gasket 22, the inner wall of the pressing plate 21 is fixedly connected with a threaded sleeve 212, the sealing gasket 22 is fixedly connected to the outer wall of the threaded sleeve 212, one side of the pressing plate 21 is fixedly connected with a first connecting frame 23, the inner wall of the first connecting frame 23 is installed with a fixed shaft 24, the outer wall of the fixed shaft 24 is rotatably connected with a connecting plate 25, one side of the pressing plate 21 is fixedly connected with a second connecting frame 26, one side of the second connecting frame 26 is fixedly connected with a fixing plate 27, the fixing plate 27 is fixedly connected to the connecting plate 25 by a fixing bolt 28, the inner wall of the connecting plate 25 is threadedly connected with a threaded column 210, the threaded column 210 is One end is fixedly connected with a knob 29, and one end of the threaded column 210 is sleeved with a top plate 211. During installation, the threaded sleeve 212 is inserted into the preset opening of the liquid inlet pipe 10, and the connecting plate 25 is rotated to make it contact the fixed plate 27. The two are fixed together by the fixing bolts 28. The threaded column 210 is driven to rotate by rotating the knob 29, so that the top plate 211 moves upward to squeeze the liquid inlet pipe 10, thereby increasing the pressure between the pressure plate 21 and the liquid inlet pipe 10, so that the sealing gasket 22 is tightly connected to the outer wall of the liquid inlet pipe 10 to prevent liquid leakage. Finally, the hydraulic sensor 31 is threadedly connected to the inside of the threaded sleeve 212 to complete the installation of the monitoring and alarm device.

[0027] During the installation operation, firstly, the threaded sleeve 212 is accurately inserted into the pre-set opening of the liquid inlet pipe 10, then the connecting plate 25 is rotated to make it just contact the fixing plate 27, and then the two are firmly fixed together by the fixing bolt 28. Next, the threaded column 210 is driven to rotate by turning the knob 29, so that the top plate 211 moves upward, thereby squeezing the liquid inlet pipe 10. In this way, the pressure between the pressing plate 21 and the liquid inlet pipe 10 will increase, prompting the sealing gasket 22 to be tightly connected to the outer wall of the liquid inlet pipe 10, effectively preventing liquid leakage. Finally, the hydraulic sensor 31 is installed inside the threaded sleeve 212 by threaded connection. At this point, the installation of the monitoring alarm device is successfully completed.

[0028] Pressure monitoring principle:

[0029] The hydraulic sensor 31 is installed inside the threaded sleeve 212. When liquid flows in the liquid inlet pipe 10, the pressure of the liquid is transmitted to the sealing gasket 22 and the pressure plate 21 through the liquid inlet pipe 10. Since the hydraulic sensor 31 is in indirect contact with the liquid inlet pipe 10 through this connection mode, it can sense the pressure change of the liquid in the liquid inlet pipe 10.

[0030] For example, if the liquid pressure in the liquid inlet pipe 10 suddenly increases or decreases, the hydraulic sensor 31 will convert this pressure change into an electrical signal. This is based on the working principle of the strain gauge or other pressure sensing elements inside the sensor. When the pressure changes, the physical properties of these sensing elements (such as resistance, capacitance, etc.) will change, thereby generating different electrical signals.

[0031] Signal transmission and processing

[0032] The electrical signal generated by the hydraulic sensor 31 will be transmitted to a monitoring system connected to it (not mentioned in the text, but such a system is usually present). This monitoring system generally includes a signal processing unit, which amplifies and filters the received electrical signal.

[0033] For example, the signal may be boosted by an amplifier to ensure that the signal can be accurately recognized by subsequent devices. At the same time, filtering can remove interference components in the signal, such as electromagnetic interference, to make the signal purer.

[0034] Alarm triggering mechanism:

[0035] The processed signal is then sent to a comparator or controller (which may be a microprocessor or dedicated control circuit in the monitoring system), where it is compared to a pre-set pressure threshold.

[0036] The normal working pressure range of the liquid transported by the liquid inlet pipe 10 is within a certain interval. When the pressure value corresponding to the signal transmitted by the hydraulic sensor 31 exceeds this normal interval (for example, too high pressure may indicate pipeline blockage, and too low pressure may indicate pipeline leakage), the comparator or controller will trigger an alarm signal. The alarm signal can be an audible alarm, which sounds an alarm through a connected speaker; or it can be a light alarm, which makes the connected indicator light flash, thereby reminding the staff that an abnormal situation has occurred in the liquid inlet pipe 10.

[0037] In this embodiment, specifically: the monitoring component 30 includes a hydraulic sensor 31, and the hydraulic sensor 31 is threadedly connected to the inner wall of the threaded sleeve 212. When inspecting and maintaining the petroleum and petrochemical pump monitoring and alarm device, the installation and disassembly operations of the monitoring component 30 can be completed by rotating the hydraulic sensor 31. The operation is simple and convenient, which saves time and improves the inspection and maintenance efficiency of the petroleum and petrochemical pump monitoring and alarm device.

[0038] In this embodiment, specifically: a probe 32 is installed at the bottom end of the hydraulic sensor 31, and the probe 32 hydraulically monitors the pipeline pressure of the petroleum and petrochemical machine pump.

[0039] In this embodiment, specifically: a control panel 33 is installed on the top of the hydraulic sensor 31 .

[0040] In this embodiment, specifically, the signal input end of the control panel 33 is signal-connected to the signal output end of the hydraulic sensor 31. The hydraulic sensor 31 sends hydraulic data to the control panel 33 to prevent abnormal pressure in the pipelines of petrochemical pumps.

[0041] In this embodiment, specifically, an audible and visual alarm 34 is installed on the top of the control panel 33. The audible and visual alarm 34 is used to give an audible and visual alarm to the nearby area to remind the staff to handle abnormal situations in time.

[0042] In this embodiment, specifically, a display screen 35 is installed on the top of the control panel 33. The display screen 35 facilitates the staff to observe the monitored data.

[0043] In this embodiment, specifically, operation buttons 36 are evenly installed on the top of the control panel 33. The operation buttons 36 facilitate the quick operation of the control panel 33.

[0044] Working principle or structural principle: During installation, insert the threaded sleeve 212 into the preset opening of the liquid inlet pipe 10, rotate the connecting plate 25 to make it contact the fixed plate 27, and fix the two together with the fixing bolt 28. Drive the threaded column 210 to rotate by rotating the knob 29, so that the top plate 211 moves upward, extruding the liquid inlet pipe 10, thereby increasing the pressure between the pressing plate 21 and the liquid inlet pipe 10, making the sealing gasket 22 closely connected to the outer wall of the liquid inlet pipe 10 to prevent liquid leakage. Finally, thread-connect the hydraulic sensor 31 inside the threaded sleeve 212 to complete the installation of the monitoring and alarm device. When overhauling and maintaining the petrochemical pump monitoring and alarm device, rotating the hydraulic sensor 31 can complete the installation and disassembly operations of the monitoring component 30. The operation is simple and convenient, saving time and improving the overhaul and maintenance efficiency of the petrochemical pump monitoring and alarm device.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
