Description

Technical Field

[0001] The present invention relates to the technical field of gas cabinets, and in particular to a device and method for monitoring a counterweight system of a Wiggins gas cabinet. Background Art

[0002] Wiggins gasholder, also known as rubber membrane dry gasholder or rubber membrane sealed converter gasholder, is an important equipment for converter gas recovery. It is used to store, stabilize and mix converter gas, realize the comprehensive utilization of gas, improve energy utilization efficiency, reduce energy waste and environmental pollution, and has the characteristics of good sealing performance, high safety and stable operation.

[0003] The gasholder leveling device is a crucial accessory for the normal operation of the gasholder. Its operating principle is as follows: A steel wire rope connects the piston and counterweight outside the cabinet to adjust the piston's balance. The steel wire rope guide pulley operates normally, and the counterweight does not fall out of its groove. This ensures that the piston remains level during its vertical movement, thus guaranteeing the safe operation of the gasholder. The reliable operation of the guide pulley, steel wire rope, and counterweight is crucial to the stability of the gasholder. Any deviation of the guide pulley, looseness of the steel wire rope, or fallout of the counterweight can easily lead to a serious accident.

[0004] Currently, the inspection of gas tanks is mainly carried out through manual inspections, which cannot achieve 24-hour uninterrupted monitoring. Once similar problems occur, it is difficult to discover them in time, resulting in a greater impact of the accident. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a Wiggins gas tank counterweight system monitoring device and method.

[0006] In order to solve the above technical problems, the technical solutions of the present invention are as follows: A Wiggins gas cabinet counterweight system monitoring device, comprising: A guide wheel state monitoring module is used to monitor the eccentricity of the guide wheel in real time. The guide wheel state monitoring module includes several groups of first laser ranging sensor groups. Each group of the first laser ranging sensor groups includes two first laser ranging sensors arranged on the same side of the guide wheel, and the distances between the two first laser ranging sensors and the plane where the guide wheel is located are equal. A wire rope state monitoring module, for real-time monitoring of the straightness of the wire rope, comprising a plurality of second laser ranging sensors, wherein the laser light emitted by each second laser ranging sensor is in the same plane as the adjacent straightened wire rope; And, a counterweight block height monitoring module is used to monitor the height of all counterweight blocks in real time. The counterweight block height monitoring module includes several groups of third laser ranging sensor groups. Each group of the third laser ranging sensor groups is fixedly arranged below adjacent counterweight blocks to detect the distance between adjacent counterweight blocks and the third laser ranging sensor groups.

[0007] As a preferred solution of the Wiggins gas tank counterweight system monitoring device of the present invention, the number of the first laser ranging sensor groups is equal to the number of the guide wheels.

[0008] As a preferred solution of the Wiggins gas tank counterweight system monitoring device of the present invention, each group of the third laser ranging sensor groups includes at least two third laser ranging sensors, and at least two of the third laser ranging sensors are arranged in the same horizontal plane.

[0009] As a preferred solution of the Wiggins gas tank counterweight system monitoring device described in the present invention, it also includes a main control module for receiving the monitoring data uploaded by the guide wheel status monitoring module, the wire rope status monitoring module and the counterweight block height monitoring module, and comparing the received monitoring data with the preset corresponding threshold value to determine whether the monitoring data is within the preset threshold range.

[0010] As a preferred solution of the Wiggins gas cabinet counterweight system monitoring device of the present invention, it further includes an alarm module; The main control module is further configured to transmit a control signal to the alarm module when the monitoring data is outside a preset threshold range, and the alarm module is configured to perform alarm processing after receiving the control signal transmitted by the main control module.

[0011] The present invention also provides a Wiggins gas cabinet counterweight system monitoring method, which is based on the above-mentioned Wiggins gas cabinet counterweight system monitoring device and includes: The eccentricity of each guide wheel is monitored in real time through the guide wheel status monitoring module; The wire rope status monitoring module monitors the straightness of each wire rope in real time; The height of all counterweights is monitored in real time through the counterweight height monitoring module; When one or more of the following situations occurs: the eccentricity of the guide wheel is greater than the preset threshold, the wire rope is not in a straight state, or the height difference between one or more counterweight blocks and the height of the remaining counterweight blocks is greater than the preset threshold, the main control module transmits a control signal to the alarm module, causing the alarm module to perform alarm processing.

[0012] As a preferred solution of the Wiggins gas cabinet counterweight system monitoring method of the present invention, the real-time monitoring of the eccentricity of each guide wheel by the guide wheel status monitoring module includes: The distance between it and the guide wheel surface is measured by two first laser ranging sensors respectively. If the difference between the distances measured by the two first laser ranging sensors is less than or equal to the first preset threshold value, it indicates that the eccentricity of the guide wheel is normal; if the difference between the distances measured by the two first laser ranging sensors is greater than the first preset threshold value, it indicates that the eccentricity of the guide wheel is abnormal.

[0013] As a preferred solution of the Wiggins gas cabinet counterweight system monitoring method of the present invention, the real-time monitoring of the straightness of each steel wire rope by the steel wire rope status monitoring module includes: The distance between it and the adjacent steel wire rope is measured by a second laser ranging sensor.

[0014] The beneficial effects of the present invention are: The present invention uses multiple laser ranging sensors distributed and installed in specific positions to measure distance values ​​in real time, and analyzes and converts the measured data to monitor abnormal conditions such as whether the gas tank guide wheel is eccentric, whether the wire rope is too loose, and whether the counterweight block is stuck due to being out of the groove. The present invention uses sensor detection, data analysis, and automatic system push to replace manual real-time monitoring of the cabinet top guide wheel and wire rope status in advance, ensuring uninterrupted monitoring of the Wiggins gas tank counterweight system and avoiding major accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0016] Figure 1 A schematic diagram of the Wiggins gas cabinet counterweight system monitoring device provided by the present invention; Figure 2 This is a flow chart of the Wiggins gas cabinet counterweight system monitoring method provided by the present invention. DETAILED DESCRIPTION

[0017] In order to make the contents of the present invention more clearly understood, the present invention is further described below in detail based on specific implementation methods in conjunction with the accompanying drawings.

[0018] This embodiment of the present application provides a monitoring device for a Wiggins gasholder counterweight system. The device includes a guide pulley status monitoring module, a wire rope status monitoring module, and a counterweight height monitoring module. These modules can respectively detect the eccentricity of the guide pulley, the tension of the wire rope, and the height of the counterweight, thereby determining whether the Wiggins gasholder counterweight system is operating normally.

[0019] Specifically, the guide pulley status monitoring module is used to monitor the eccentricity of the wire rope guide pulley in real time. The module includes several sets of first laser ranging sensors, with the number of first laser ranging sensor sets matching the number of wire rope guide pulleys. One set of first laser ranging sensors is mounted on one side of each wire rope guide pulley.

[0020] Each first laser ranging sensor group includes two first laser ranging sensors. These sensors are fixedly mounted on either side of adjacent wire rope guide pulleys. When the guide pulleys are operating normally, the lasers emitted by both sensors are perpendicular to the plane of the guide pulleys, and the distances between the sensors and the plane of the guide pulleys are equal. The two sensors measure the distance between themselves and the plane of the guide pulleys in real time. If the difference between the two measured values ​​is too large, it indicates that the guide pulleys are severely eccentric and requires prompt repair.

[0021] The wire rope condition monitoring module is used to monitor the tension of the wire rope in real time. There are multiple wire ropes attached to the guide pulley, and under normal conditions, all of them are in a straight state. The wire rope condition monitoring module includes a second laser ranging sensor, equal to the number of wire ropes. A second laser ranging sensor is fixedly mounted on one side of each wire rope. The laser emitted by the second laser ranging sensor is aimed directly at the wire rope, meaning that the laser emitted by the second laser ranging sensor is in the same plane as the adjacent, straightened wire rope. The second laser ranging sensor measures the distance between itself and the adjacent wire rope. Under normal conditions, the positions of the wire rope and the second laser ranging sensor do not change significantly, so the difference between the same set of measured data should be minimal. Any abnormal data changes (such as large differences or inability to measure data) indicate that the wire rope is too loose due to problems such as obstruction by the guide pulley or counterweight.

[0022] The counterweight height monitoring module is used to monitor the height of all counterweights in real time. The counterweights are distributed along the sides of the gas tank. Steel wire ropes of the same length and specification connect the weights to the pistons via guide pulleys, ensuring proper balancing of the pistons. The counterweight height monitoring module includes several sets of third-party laser ranging sensors, each matching the number of counterweights. Each set consists of two third-party laser ranging sensors, fixed below adjacent counterweights to detect the distance between the two third-party laser ranging sensors and the counterweights. Under normal operation, the counterweights are at the same height. If a weight is out of its slot, it will be blocked by a bracket and unable to follow the piston's upward and downward motion, oscillating out of the same plane as the other normally operating pistons. If the data measured by one or more third-party laser ranging sensor sets differ significantly from that measured by other sets, this indicates that the counterweights adjacent to that set of third-party laser ranging sensors are out of their slots and require immediate emergency attention.

[0023] In this embodiment, the first laser ranging sensor, the second laser ranging sensor and the third laser ranging sensor are all explosion-proof laser ranging sensors, three-wire system, 24V power supply, and the measurement signal is 4-20ma output.

[0024] In addition, the Wiggins gas tank counterweight system monitoring device also includes a main control module and an alarm module. Among them, the main control module is used to receive the monitoring data uploaded by the guide wheel status monitoring module, the wire rope status monitoring module and the counterweight block height monitoring module, and compare the received monitoring data with the preset corresponding threshold value to determine whether the monitoring data is within the preset threshold range. If the monitoring data is outside the preset threshold range, a control signal is transmitted to the alarm module. The alarm module is used to perform alarm processing after receiving the control signal transmitted by the main control module, reminding the operator that there is an abnormality in the Wiggins gas tank counterweight system and it needs to be processed as soon as possible.

[0025] In this embodiment, the data transmission of the laser ranging sensor adopts wireless networking, that is, the 485 communication signal output by the laser ranging sensor is connected to the wireless collector, and the 485 signal output by the centralized controller is converted into a TCP / IP protocol signal using a Modbus gateway for transmission. All laser ranging sensor signals are connected to the centralized control room and centralized control alarm system based on the EMS energy network, and the on-site laser ranging data in the area are collected and networked.

[0026] In addition, the present application also provides a Wiggins gas cabinet counterweight system monitoring method, which is based on the Wiggins gas cabinet counterweight system monitoring device described above. The method specifically includes the following steps: Step S101: Monitor the eccentricity of each guide wheel in real time through the guide wheel status monitoring module.

[0027] Specifically, the distance between it and the guide wheel surface is measured by two first laser ranging sensors respectively. If the difference between the distances measured by the two first laser ranging sensors is less than or equal to the first preset threshold value, it indicates that the eccentricity of the guide wheel is normal; if the difference between the distances measured by the two first laser ranging sensors is greater than the first preset threshold value, it indicates that the eccentricity of the guide wheel is abnormal.

[0028] Step S102: Monitor the straightness of each steel wire rope in real time through the steel wire rope status monitoring module.

[0029] Specifically, the distance between it and the adjacent steel wire rope is measured by the second laser ranging sensor. If the distance measured by the second laser ranging sensor is within the second threshold range, it indicates that the steel wire rope is in a straight state; if the distance measured by the second laser ranging sensor is outside the second threshold range or no data is measured, it indicates that the steel wire rope is in a non-straight state.

[0030] Step S103: monitoring the heights of all counterweights in real time through the counterweight height monitoring module.

[0031] Step S104: When one or more of the following occurs: the eccentricity of the guide wheel is greater than the preset threshold, the wire rope is not in a straight state, or the height difference between one or more counterweight blocks and the height of the remaining counterweight blocks is greater than the preset threshold, the main control module transmits a control signal to the alarm module, causing the alarm module to perform alarm processing.

[0032] Therefore, the technical solution of the present application uses multiple laser ranging sensors distributed and installed in specific positions to measure distance values ​​in real time, and analyzes and converts the measurement data to monitor whether there is eccentricity in the gas tank guide wheel, whether the wire rope is too loose, whether the counterweight block is stuck due to being out of the groove, and other abnormal conditions. The method of using sensor detection, data analysis, and automatic system push replaces manual real-time monitoring of the cabinet top guide wheel and wire rope status in advance, ensuring uninterrupted monitoring of the Wiggins gas tank counterweight system and avoiding major accidents.

[0033] In addition to the above embodiments, the present invention may also have other implementation methods; any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
