Description

Technical Field

[0001] This application relates to the field of pipeline monitoring system technology, and more particularly to an oil pipeline monitor. Background Technology

[0002] Monitoring the state of oil in the oil circuit is mostly achieved through instruments installed on the oil pipes. Since the instruments on the oil pipes are mostly traditional mechanical structures, they work and display independently. When the pressure in the oil pipe increases, it is difficult to quickly determine which instrument is responsible for the pipeline that has a problem, which will affect the timeliness of remediation. Summary of the Invention

[0003] The purpose of this application is to provide an oil circuit monitor that is convenient for centralized monitoring.

[0004] To achieve the above objectives, this application provides an oil circuit monitor: comprising a hub board and several pipe units, each pipe unit being connected to the hub board via a signal acquisition line, one end of which is connected to a pressure sensor, the pressure sensor being located inside the pipe unit, the sensing surface of the pressure sensor being parallel to the axis of the pipe unit, the pipe unit being adapted to be connected to an oil pipeline, and the hub board being adapted to be fixedly connected to the outside of the oil pipeline via a sleeve to ensure the stability of the hub board.

[0005] As a preferred embodiment, the pressure sensor is flat, with both end faces of the pressure sensor parallel to the axis of the pipe unit. Each pipe unit has an embedded end at both ends, suitable for insertion into the oil pipeline to allow oil to pass through.

[0006] As a preferred embodiment, the side wall of the pipe unit has a through hole, and one end of the signal acquisition line connected to the pressure sensor is fitted with a sealing tube. The sealing tube passes through the through hole to form a sealing structure to prevent oil leakage.

[0007] As a preferred embodiment, the hub board has several connection ports on its side, and the other end of the signal acquisition line is connected to a plug terminal, which is suitable for plugging into the connection port to achieve electrical connection and realize centralized transmission of detection signals.

[0008] As a preferred embodiment, one end of the hub is also connected to a bus, which is electrically connected to all the wiring ports. The end of the signal acquisition line connected to the plug has a corrugated sleeve to reduce the probability of plug breakage.

[0009] As a preferred embodiment, the sleeve includes a first clamp and a second clamp, and the hub plate is fixedly connected to the outer surface of the first clamp. The first clamp and the second clamp are adapted to engage together on the outside of the oil pipeline, which facilitates the installation of the hub plate.

[0010] As a preferred embodiment, the first clamp and the second clamp are fixedly connected by a connector to facilitate disassembly and assembly.

[0011] As a preferred embodiment, the outer side of the first clamp has a first connecting plate with a first through hole, and the outer side of the second clamp has a second connecting plate with a second through hole. The connecting component includes a bolt and a nut. The bolt passes through the first through hole and the second through hole and engages with the nut, and is fixedly installed by tightening.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By installing a pressure sensor in the pipe unit that can be connected to the oil pipeline and transmitting the detection signal to the computer through the hub, the working status of the oil circuit can be centrally monitored. The problematic oil pipeline can be quickly identified through the computer monitor, which improves the efficiency of remediation.

[0014] (2) By reserving multiple connection ports on the hub, the number of oil pipes to be inspected is more flexible, and a pipe sleeve structure is set at the rear of the hub, so that the hub can be quickly installed on the spot and the configuration is more convenient.

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8The oil circuit monitor shown includes a hub board 2 and several pipe units 4. The hub board 2 contains circuitry. Each pipe unit 4 is connected to the hub board 2 via a signal acquisition line 3. The signal acquisition line 3 is used to transmit electrical signals. One end of the signal acquisition line 3 is connected to a pressure sensor 304, which can convert oil pressure into an electrical signal. The pressure sensor 304 is located inside the pipe unit 4, and the sensing surface of the pressure sensor 304 is parallel to the axis of the pipe unit 4. In this embodiment, the pressure sensor 304 is flat, and both ends of the pressure sensor 304 are parallel to the axis of the pipe unit 4. The sensing surface of the pressure sensor 304 is located on one of the end faces.

[0029] A through hole 401 is provided on the side wall of the tube unit 4, connecting the inner and outer walls of the tube unit 4. A sealing tube 303 is fitted onto one end of the signal acquisition line 3 connected to the pressure sensor 304. The sealing tube 303 passes through the through hole 401 and is in close contact with the inner wall of the through hole 401, forming a sealing surface. Because the sealing tube 303 is elastic, it achieves a good seal after interference fit with the through hole 401. Furthermore, a curing adhesive is usually applied to the outside of the sealing tube 303 to effectively ensure its stability within the through hole 401. Several connection ports 202 are provided on the side of the hub plate 2, the number of which is greater than or equal to that of the signal acquisition line 3. The signal acquisition line 3 has a connector 301 at the other end away from the pressure sensor 304, which is used to connect to the wiring port 202 for electrical connection. All signals detected by the pressure sensors 304 can flow to the hub board 2. One end of the hub board 2 is also connected to the bus 201, which is electrically connected to all the wiring ports 202 for transmitting all signals detected by the pressure sensors 304 to the external processor and display. The end of the signal acquisition line 3 connected to the connector 301 has a corrugated sleeve 302, which can improve the flexibility of the connection between the signal acquisition line 3 and the connector 301, thereby reducing the probability of breakage at the end of the connector 301.

[0030] The pipe unit 4 needs to be connected to the oil pipeline to enable the monitoring function. Each pipe unit 4 has an embedded end 402 at both ends for insertion into the oil pipeline. After the embedded end 402 is inserted from the end of the oil pipeline, a clamp is also fitted and tightened at the end of the oil pipeline. This ensures the airtightness of the pipe unit 4 after it is connected to the oil pipeline.

[0031] The hub plate 2 is adapted to be fixedly connected to the outside of the oil pipeline via the sleeve 1. Specifically, the sleeve 1 includes a first clamp 110 and a second clamp 120. The hub plate 2 is fixedly connected to the middle of the outer surface of the first clamp 110. The first clamp 110 and the second clamp 120 need to engage together on the outside of the oil pipeline. The first clamp 110 and the second clamp 120 are fixedly connected by a connector 5. The outer surface of the first clamp 110 has a pair of symmetrical first connecting plates 111. Each first connecting plate 111... Both clamps 110 and 120 are provided with a first through hole 112. The outer side of the second clamp 120 has a pair of symmetrical second connecting plates 121. Each second connecting plate 121 is provided with a second through hole 122. The connector 5 includes a bolt 501 and a nut 502. The bolt 501 passes through the first through hole 112 and the second through hole 122 and cooperates with the nut 502. By tightening, the first clamp 110 and the second clamp 120 are fixed, and the first clamp 110 and the second clamp 120 are fixed outside the oil pipeline.

[0032] Working principle: When in use, take the corresponding number of signal acquisition lines 3 and pipe units 4 according to the number of oil lines to be detected. First, number the pipe units 4 and connect them into the oil pipeline. Then, insert the plug end 301 of the signal acquisition line 3 into the wiring port 202 of the hub board 2. Then, fix the hub board 2 outside the appropriate oil pipeline. Finally, connect the bus 201 to the computer terminal. The oil pressure changes in each oil line can be monitored in real time through the same terminal.
