Detailed Description

The embodiment of the application provides a river bottom pipeline monitoring system and a generator, can detect the position condition of a river bottom pipeline in real time, realizes all-weather monitoring of the buried depth of the pipeline, and is favorable for timely protecting the pipeline when the pipeline position is abnormal.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

a river bottom pipeline monitoring system comprising: the intelligent terminal comprises a generator, a current collector and an intelligent terminal, wherein the generator is connected with the current collector, and the current collector is connected with the intelligent terminal; the main shaft of the generator is vertical to the river bed and buried at the river bottom, and the tail end of the main shaft is connected with a pipeline buried at the river bottom; the main shaft is provided with at least one group of rotating blades, when the rotating blades are completely exposed in water, the exposed rotating blades rotate under the action of water flow to drive the main shaft of the generator to rotate, so that the generator generates a current signal, and the strength of the current signal is positively correlated with the number of the rotating blade groups; the intelligent terminal is used for displaying the current intensity value of the received current signal, and the current intensity value is used for reflecting the distance between the pipeline and the current riverbed reference surface.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

In a first aspect, an embodiment of the present invention provides a river bottom pipeline monitoring system. Specifically, as shown in fig. 1, the system includes a generator 20, a current collector 40, and an intelligent terminal 60, where the generator 20 is connected to the current collector 40, and the current collector 40 is connected to the intelligent terminal 60.

Wherein, the main shaft 90 of the generator 20 is vertical to the river bed and buried in the river bottom, and the end of the main shaft 90 is connected with the pipeline 200 buried in the river bottom. In order to stabilize the main shaft 90 of the generator and prevent the main shaft 90 of the generator from deviating, the system may further include a fixing frame 10. The tail end of the main shaft 90 of the generator is fixed on the outer wall of the pipeline through the fixing frame 10, so that the main shaft 90 of the generator 20 is perpendicular to the riverbed and fixed on the outer wall of the pipeline 200, and effectiveness and accuracy of collected data are improved.

In particular, the main shaft is equipped with at least one set of rotating blades 30. The rotating blades 30 are sleeved on the main shaft 90, and can drive the main shaft 90 to rotate independently. In an initial installation state, the rotating blades are perpendicular to a river bed along with a main shaft of the generator and buried at the river bottom, are limited by covered silt and cannot rotate, and the generator cannot generate a current signal. However, the river bed is prone to erosion due to the erosion and corrosion of river water, so that the rotating blades originally buried in the river bottom are gradually exposed in the water. When the rotating blades are completely exposed in water, the exposed rotating blades rotate under the action of water flow to drive the main shaft of the generator to rotate, so that the generator generates a current signal. It can be understood that, along the depth direction of the river bed, as the river bed erodes, the at least one set of rotating blades gradually exposes from top to bottom, that is, the rotating blades gradually rotate under the action of water flow, and the intensity of the current signal generated by the generator is positively correlated with the number of the rotating blade sets.

In a specific embodiment, in order to know each stage of the riverbed being flushed and realize more comprehensive monitoring of the river bottom pipeline, a longer generator main shaft can be arranged, so that a plurality of groups of rotating blades can be arranged on the main shaft. For convenience of subsequent calculation, multiple groups of rotating blades can be arranged on the main shaft at equal intervals along the length direction of the main shaft.

Of course, in other embodiments of the present invention, the above-mentioned multiple groups of rotating blades may also adopt a method of setting at unequal intervals, and the specific setting mode may be selected according to actual situations.

In addition, for convenience of calculation, when the rotary blades 30 are provided in plural sets, the vertical distance between the rotary blade closest to the pipe and the upper surface of the pipe may be equal to the distance between two adjacent sets of rotary blades.

Of course, in other embodiments of the present invention, only one set of rotating blades 30 may be provided. For example, a set of rotating blades may be mounted on the main shaft of the generator at a predetermined distance from the surface of the pipe. The predetermined distance may be set empirically and through multiple trials. When the group of rotating blades is completely exposed and rotates, the pipeline burial depth reaches the early warning position, and the maintenance is required in time.

In order to ensure the detection accuracy, all the rotating blades are not exposed when being buried. In order to ensure that the rotary blades completely exposed in water can flexibly rotate, when the rotary blades are submerged in the river bottom, the generator and the periphery of the rotary blades can be filled with substances which are easily washed away by water, so that the fillers around the rotary blades can be easily cleaned by water flow, and the rotary blades and the generator are prevented from being interfered by obstacles such as rough stones. For example, fine sand may be used as the filler.

In this embodiment, each set of rotating blades is independent from each other, and each set of rotating blades 30 and the generator main shaft 90 are in a driving-driven relationship, that is, each set of rotating blades can drive the generator main shaft to rotate, and when the generator main shaft is driven to rotate, the other sets of rotating blades are not interfered.

As an embodiment, as shown in fig. 2, the rotary blade 30 in the present embodiment may include a collar 100, a return spring 101, and a plurality of blades 102. The lantern ring 100 is sleeved on the main shaft 90 of the generator, the return spring 101 is installed on the inner wall of the lantern ring 100, and the blades 102 are assembled on the outer wall of the lantern ring 100. The outer wall of the generator main shaft 90 is provided with a clamping groove 103 matched with the return spring 101.

Specifically, as shown in fig. 2, the return spring 101 may include a spring and a spring plate, one end of the spring is connected to the inner wall of the collar, and the other end of the spring is connected to a surface of the spring plate facing the inner wall of the collar. One end of the elastic sheet is fixed on the inner wall of the lantern ring, and the other end of the elastic sheet extends into the clamping groove on the main shaft and is matched with the corresponding clamping groove on the main shaft. When the rotary blade 30 rotates, the tail end of the spring sheet of the return spring 101 moves into the slot 103, and the main shaft 90 is driven to rotate.

Optionally, the elastic sheet may be arc-shaped, and the distance from one end connected with the lantern ring to the other end extending into the clamping groove gradually increases. Correspondingly, the groove bottom of the clamping groove to the groove top of the adjacent clamping groove can also be arc-shaped, and the distance from the outer surface of the main shaft to the inner wall of the lantern ring is gradually reduced and then is kept unchanged from the groove bottom to the groove top of the adjacent clamping groove. Therefore, the force applied to the elastic sheet of other non-rotating blades which are not completely exposed when the main shaft rotates is reduced, and the interference to other groups of rotating blades when the main shaft of the generator rotates is further reduced.

As an implementation manner, 3 return springs may be disposed on the inner wall of the collar of each group of rotating blades at equal intervals, and correspondingly, 3 slots corresponding to the 3 return springs are disposed on the outer wall of the main shaft of the generator along the circumferential direction. This is beneficial to driving the main shaft to rotate more stably. Of course, in other embodiments of the present invention, other numbers of return springs, such as 2, 4 or 5 return springs, may be disposed in each group of rotating blades, and a corresponding number of slots may be disposed therein.

Thus, when any one set of the rotating blades 30 is driven by water flow to rotate the generator main shaft, the elastic pieces of the return springs 101 of the other rotating blades can be compressed towards the inner wall of the sleeve ring 100 when being subjected to pressure applied by the generator main shaft 90, so that the other rotating blades 30 are prevented from rotating along with the rotation of the main shaft, namely, the other rotating blades 30 are prevented from being influenced by the rotation of the main shaft. Thus, the main and driven relation between each rotating blade and the main shaft of the generator can be realized.

The current collector 40 of the system is used for collecting the current signal generated by the generator and sending the current signal to the intelligent terminal 60. For example, current collector 40 may be of the ASAM-2510-8L or C-7017 type.

In a specific embodiment, the system may further include: a radio signal transmitting device 70 and a radio signal receiving device 80. The current collector 40 is connected with a radio signal transmitting device 70, the radio signal transmitting device 70 is in communication connection with a radio signal receiving device 80, and the radio signal receiving device 70 is connected with the intelligent terminal 60. The current signal collected by the current collector 40 is transmitted to the intelligent terminal 60 through the radio signal transmitting device 70 and the radio signal receiving device 80. Thereby enabling the system to achieve long-distance wireless signal transmission. For example, the radio signal transmitting device 70 and the radio signal receiving device 80 may be a laser transmitter, a microwave transmitter, a mechanical wave transmitter, and the like.

Of course, in other embodiments of the present invention, a cable connection may also be used between the current collector 40 and the intelligent terminal 60, and is not limited herein.

It is understood that the system further comprises: and the analog-to-digital converter 50 is connected with the current collector 40 and the intelligent terminal 60 respectively. The analog signal collected by the current collector 40 is converted into a numerical signal by the analog-to-digital converter 50, and is sent to the intelligent terminal 60. And then displayed by a current intensity acquisition system of the intelligent terminal 60, the number of groups of the rotating blades 30 is judged according to the current intensity value, and the real-time distance from the pipeline to the riverbed reference surface is calculated according to the number of groups of the rotating blades 30. For example, the analog-to-digital converter may be of the type AD7948ARSZ-B or AD7948 BNZ.

Further, the current collector 40 may be configured to: when each group of rotating blades rotates, the current collector collects corresponding current signals. Therefore, the intelligent terminal can determine the number of groups of rotating blades which rotate according to the current signals.

Specifically, the intelligent terminal 60 is used for displaying the current strength value of the received current signal. The current intensity value can reflect the distance between the pipeline and the current riverbed reference surface. It will be appreciated that the greater the magnitude of the current displayed, the greater the number of sets of rotating blades which are shown to be rotating, i.e. fully exposed, and correspondingly, the smaller the distance between the pipe and the current bed datum, i.e. the shallower the pipe burial depth. Therefore, relevant workers can know the current buried depth condition of the pipeline according to experience by reading the current intensity value, and therefore whether the pipeline is in an abnormal condition or not is judged.

Specifically, the intelligent terminal 60 may employ a device having a data processing function, such as a central controller, a PC (Personal Computer), a PDA (Personal Digital Assistant), or a mobile terminal.

Further, in order to more intuitively obtain the current burial depth of the pipeline, the intelligent terminal 60 may be further configured to determine the number of sets of rotating blades that rotate according to the current intensity value of the current signal when receiving the current signal, and calculate the distance between the pipeline and the current riverbed reference surface according to the number of sets. The process may be implemented by hardware circuitry. For example, the implementation can be realized by designing a comparison circuit, a logic calculation circuit, and the like, and details are not described here.

In a specific embodiment, the process of determining the distance between the pipeline and the current riverbed reference plane according to the current intensity value of the intelligent terminal current signal may include:

and matching the current intensity value displayed by the intelligent terminal with a preset corresponding table, and determining the number of groups of rotating blades corresponding to the current intensity value, wherein the preset corresponding table comprises the corresponding relation between the number of the groups of rotating blades and the range of the current intensity value.

Specifically, when the number of groups of rotating blades is 1, two corresponding relationships exist between the number of groups of rotating blades and the range of the current intensity value, that is, when the current intensity value is zero, the number of corresponding groups of rotating blades is zero; when the current intensity value is in the range (a, b), the number of the corresponding rotating blade groups which are rotated is 1.

Assuming that the number of sets of rotating blades is 4, the preset correspondence table includes: and 4, the number of the rotating blade groups rotating is in corresponding relation with the current intensity value range. For example, when the current intensity value is zero, the number of the corresponding rotating blade sets which rotate is zero; when the current intensity value is in the range (a, b), the number of the corresponding rotating blade groups which rotate is 1; when the current intensity value is in the range (c, d), the number of the corresponding rotating blade groups which rotate is 2; when the current intensity value is in the range (e, f), the number of the corresponding rotating blade groups which rotate is 3; when the current intensity value is in the range (g, h), the number of the corresponding rotating blade groups that are rotated is 4. Therefore, the intelligent terminal can determine the interval of the current intensity value through the received current intensity value to obtain the corresponding group number of the rotating blades which rotate.

Further, after the number of the corresponding groups of the rotating blades which rotate is obtained, the worker can determine the distance between the pipeline and the current riverbed reference surface based on the number of the groups of the rotating blades which rotate according to experience, so as to judge whether the current pipeline is in an abnormal condition.

Alternatively, the distance between the pipeline and the current riverbed reference surface is obtained through simple calculation. In a particular embodiment, when the system includes multiple sets of rotating blades, the calculation may be: and obtaining the depth of the eroded riverbed based on the number of groups of rotating blades, the distance between the rotating blade closest to the riverbed and the initial riverbed reference surface and the distance between two adjacent groups of rotating blades. And (4) making a difference value between the distance from the pipeline to the initial riverbed reference surface and the riverbed depth to obtain the distance between the pipeline and the current riverbed reference surface.

Specifically, the buried depth of the pipeline may be obtained in advance by manual measurement or other means. After the main shaft is buried in the river bottom, the initial distance between the rotating blade nearest to the river bed and the reference plane of the river bed is measured. In addition, the distance between two adjacent groups of rotating blades is a preset value and is known. And obtaining the number of groups of rotating blades which rotate based on the method. And obtaining the distance between the pipeline and the current riverbed reference surface according to the data.

For example, the distance between the pipeline and the current riverbed reference plane can be calculated by the following formula:

x＝H-[h+(n-1)Δh]

wherein x is the real-time distance of the pipeline from the riverbed reference surface and is the unit m; h is the buried depth of the pipeline and the unit m; h is the distance between the rotating blade on the uppermost layer and the riverbed reference surface, and the unit is m; n is the number of groups of rotating blades; Δ h is the distance between two adjacent rotating blades in m.

Further, in a specific embodiment, the intelligent terminal may be further configured to initiate an alarm when the current signal is received and/or the displayed current intensity value exceeds a preset intensity. Therefore, the early warning is favorably carried out on abnormal events such as shallow buried depth of the pipeline, water conservation facility failure, exposed pipeline, direct suspension or floating pipe and the like.

The early warning condition may be set according to actual experience, for example, may be set as: and when the distance between the pipeline and the current riverbed reference surface is smaller than a preset distance threshold value, alarming is initiated so that related workers can perform protection treatment in time. The alarm mode can be various, and in one implementation mode, the alarm can be given through an alarm module arranged in the intelligent terminal or externally connected with the intelligent terminal. When the intelligent terminal receives the current signal and/or when the distance between the pipeline and the current riverbed reference surface reaches the early warning condition, an alarm instruction is issued to the alarm module, and the alarm module is controlled to give an alarm, such as sound, light and vibration. For example, the alarm module may include one or more of an audible and visual alarm circuit, a voice alarm circuit, a buzzer, and the like. Or, the intelligent terminal can also send alarm information to the mobile terminal of the related staff when receiving the current signal and/or when the distance between the pipeline and the current riverbed reference surface reaches the early warning condition, so that the related staff is not required to be on site and monitored all the time.

Specifically, when the rotary blade is submerged, the rotary blade can be arranged at an emergency prompting position before the pipeline is possibly abnormal, which is obtained through experiments. Because the rotating blades are buried at the river bottom in advance and are in a static state, the generator is in a stagnation state at the moment, and the current signal received by the intelligent terminal is zero. When the intelligent terminal receives the current signal, the rotating blade is in a rotating state, and the state indicates that the river bed is eroded to a pre-buried emergency prompt position. The intelligent terminal sends out an alarm to prompt the staff to timely make treatment.

Of course, the rotary blade can be arranged at other positions besides the emergency prompting position before the pipeline is possible to be abnormal, and the position can be determined according to actual conditions.

The rotating blades can be a group of rotating blades or a plurality of groups of rotating blades, and when the rotating blades are a plurality of groups of rotating blades, each group of rotating blades can be arranged at different positions from a river bed to a pipeline according to experimental experience. Therefore, the number of groups of rotating blades which rotate can be determined according to the current intensity value of the current signal, and the distance between the pipeline and the current riverbed reference surface is further obtained. When the distance from the current riverbed reference surface to the pipeline is a safe distance, the intelligent terminal normally displays the current distance condition; when the distance between the pipeline and the current riverbed reference surface reaches a preset early warning condition, the intelligent terminal gives an alarm to prompt a worker to timely perform treatment.

Or when the distance from the current riverbed reference surface to the pipeline is a safe distance, the intelligent terminal sends out a prompt alarm to prompt staff to notice; when the distance between the pipeline and the current riverbed reference surface reaches a preset early warning condition, the intelligent terminal sends out an emergency alarm to prompt staff to timely process.

The river bottom pipeline monitoring method of the present application will be described in detail below with reference to specific examples:

in the specific implementation process, it is assumed that the initial distance between the rotating blade closest to the riverbed and the reference surface of the riverbed is 0.3m, the buried depth of the pipeline is 3m, and the distance between two adjacent rotating blades is 0.6m, which is measured during the initial burying. The river bed moves downwards in depth under the action of long-time erosion, when the adjacent rotating blade of the rotating blade closest to the river bed rotates, the current intensity value displayed by the intelligent terminal is 2I (assuming that I is the current intensity value generated when the rotating blade closest to the river bed rotates), and if the number n of the rotating blade groups determined by the current intensity value and rotating is 2, the real-time distance from the pipeline to the current river bed reference surface can be further calculated according to the formula as follows:

x＝3-[0.3+(2-1)×0.6]＝2.1m

the utility model provides a river bottom pipeline monitoring system, this system can realize the self-sufficient of electric power, but the buried depth condition of automatic monitoring pipeline need not on-the-spot manual operation.

According to the current intensity value displayed by the intelligent terminal, related workers can timely know the buried depth condition of the pipeline, so that whether the current pipeline is abnormal or not can be judged based on the buried depth, corresponding intervention measures can be timely taken before the pipeline is in danger of leakage, and guarantee is provided for safe operation of the pipeline.

In a second aspect, based on the same concept, the present embodiment provides a generator, as shown in fig. 3, including:

the generator comprises a generator body 301, a main shaft 302 and a plurality of groups of rotating blades 303, wherein the rotating blades 303 are assembled on the generator main shaft 302. When there is a rotating blade 303 that rotates due to an external force, the rotating blade 303 drives the main shaft 302 to rotate, so that the generator 300 generates a current signal, wherein the strength of the current signal is positively correlated to the number of rotating blades.

It should be noted that the external force may be various forces that can rotate the rotating blade, such as: wind power, water power, etc. For example, the generator can be applied to the river bottom pipeline monitoring system to realize monitoring of underwater buried pipelines. Of course, the method can also be applied to the equipment burial depth monitoring in other scenes, and is not limited here.

In practical application, when the generator is applied to monitoring the buried depth of an underwater pipeline or other underwater equipment, the main shaft of the generator can be vertically buried under a river bed, and the tail end of the main shaft is fixed on the surface of the pipeline or equipment to be detected. Therefore, when the rotating blades are completely exposed in water, the exposed rotating blades rotate under the action of water flow, the rotating blades drive the main shaft to rotate, so that the generator generates a current signal, and the burial depth of the pipeline or equipment to be detected can be obtained by detecting the current intensity value of the current signal.

In particular, the rotating blade may include a collar, a return spring, and a plurality of blades. The lantern ring is sleeved on the main shaft, the return spring is installed on the inner wall of the lantern ring, and the blades are assembled on the outer wall of the lantern ring. The outer wall of the main shaft is provided with a clamping groove matched with the return spring, and when the rotating blade rotates, the tail end of the elastic sheet of the return spring moves into the clamping groove to drive the main shaft to rotate. The elastic sheet of the return spring can be compressed towards the inner wall of the sleeve ring when the elastic sheet is subjected to pressure applied by the main shaft, so that other rotating blades are prevented from rotating along with the rotation of the main shaft.

Further, the return spring may include a spring and a resilient plate. One end of the spring is connected with the inner wall of the lantern ring, and the other end of the spring is connected with one surface of the elastic sheet, which faces the inner wall of the lantern ring. One end of the elastic sheet is fixed on the inner wall of the lantern ring, and the other end of the elastic sheet extends into the clamping groove on the main shaft and is matched with the corresponding clamping groove on the main shaft. When the rotating blade rotates, the tail end of the elastic sheet of the return spring moves into the clamping groove to drive the main shaft to rotate.
