Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring equipment, in particular to a hydrological monitoring device with an alarm structure. BACKGROUND

[0002] The hydrological monitoring device is suitable for real-time monitoring of hydrological parameters of rivers, lakes, reservoirs, channels and underground water by hydrological departments and local guarantee departments, and the monitoring content includes water level, flow, flow rate, rainfall (snow), evaporation, sediment, ice, soil moisture, water quality, etc.

[0003] The response made according to the monitoring result includes local response and data remote transmission. The local response is generally set as follows: after the acquisition terminal acquires the monitoring value, it is determined whether to output a local alarm according to the monitoring value, and when it is determined that the local alarm needs to be executed, the alarm action is executed through the locally set sound / light alarm device. The data remote transmission is generally as follows: in order to feed back the monitoring result to the data receiving end in time, the acquisition terminal is generally set in a wireless signal coverage area, and the data is transmitted wirelessly through a GPRS base station.

[0004] In view of the above response, in the prior art, hydrological monitoring is performed on each position around the city and necessary hydrological monitoring is performed on the main stream of the river, and the characteristics of comprehensive coverage and less shielding of the base station are utilized, so that remote communication can generally be completed through the existing network coverage. In some areas without signal or with weak signal, the data remote transmission purpose can also be achieved through signal enhancement. However, in specific implementation, according to different signal enhancement methods, there are problems such as limited signal enhancement, large investment, large energy demand, high maintenance requirement, etc. In some remote mountain streams, when optical fiber repeater equipment is used for data transmission, because of factors such as construction cost, power supply, and system protection, it is not suitable to set up hydrological monitoring in these areas, which will greatly restrict the role of hydrological monitoring in mountain flood monitoring. The existing local response method has the limitation of narrow coverage range. SUMMARY

[0009] More preferably, the device frame is a door-shaped frame comprising two vertical rods and a horizontal rod, and the guide cylinder is a component part of one of the vertical rods.

[0011] More preferably, the lower end of the connecting rod is provided with a lower-end-opened cover which is invertedly buckled to the upper end of the guide cylinder, and the locking member is a locking bolt.

[0012] More preferably, the hydrological module installed on the device frame is further provided, the hydrological module serving as a collection terminal of hydrological data, the hydrological module comprising a swing shaft, a swing rod and a first floating ball, the swing shaft being fixed to the device frame, the upper end of the swing rod being hingedly connected to the device frame through the swing shaft, and the first floating ball being fixed to the lower end of the swing rod, the axis direction of the swing shaft satisfying that the first floating ball can swing from the side with the water permeable hole to the side with the through hole, and the hydrological module determining the liquid level hydrological data by monitoring the swing angle of the swing rod.

[0013] More preferably, the second float also includes a power supply module for powering the second alarm device and the control module.

[0017] The second buoy can issue alarms to the surrounding area while floating, thereby effectively expanding the alarm coverage or serving as a supplement to alarm issuance.

[0018] As the water level in the stream rises, the relative positions of the permeable holes and the through holes make it easy for the second float to escape from the guide tube, thus making the hydrological monitoring device itself highly reliable. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the embodiments, but the present invention is not limited to the following embodiments:

[0029] Example 1:

[0030] like Figures 1 to 8 As shown, a hydrological monitoring device with an alarm structure includes a device frame 1 and an alarm structure installed on the device frame 1. The alarm structure includes a guide tube 8 and a second float 13 disposed inside the guide tube 8. On a pair of opposite sides of the guide tube 8, a water-permeable hole 12 is provided on one side and a through hole 6 is provided on the other side. The size of the through hole 6 is such that the second float 13 can pass through the through hole 6. The second float 13 encapsulates a control module and a second alarm device. When the control module determines that the second float 13 has detached from the guide tube 8, it controls the second alarm device to emit an audible alarm or a visual alarm.

[0031] In the existing mountain hydrological monitoring operation, when monitoring the stream and mountain torrents, since the streams are mostly located in the valley and gully areas, some monitoring points of the streams cannot be effectively covered by the base station signals. The device migration method and optical fiber repeater are used to achieve wireless data connection, which has the problems of large equipment investment, long design and construction period, high requirement for post-maintenance, and poor flexibility of monitoring point layout. The relatively easy signal reflection and antenna extension technology is simple to implement, but the effect is very limited and is not suitable for all monitoring points. The active signal amplification technology also has the problems of multiple devices and high requirement for power distribution. At the same time, in the areas where there is no signal or poor signal quality at the monitoring point, even if the monitoring signal is wirelessly transmitted through various means, when the mountain torrents occur, which generally have the characteristics of rapid outbreak, the signals are transmitted to the local management department or the hydrological department, and if the warning method of sending warning through mobile phone communication is used, the coverage of the warning along the stream area may not be comprehensive, and the recipients may not read the warning in time, which may cause the warning to be invalid. The alarm device of the traditional hydrological monitoring device can respond in time according to the monitoring results, but it can only cover the surrounding area of the monitoring point. In summary, the present scheme proposes a hydrological monitoring scheme with a mobile alarm structure.

[0032] The working principle of the present scheme is as follows: before the mountain torrents occur, the guide cylinder 8 is installed by the device frame 1, one side provided with the water permeable hole 12 faces the upstream of the stream, and the other side provided with the through hole 6 faces the downstream of the stream. The height of the through hole 6 is the warning height of the stream water surface. When the stream level rises due to the occurrence of mountain torrents, the water enters the inside of the guide cylinder 8 through the water permeable hole 12, and the second floating ball 13 floats in the guide cylinder 8. When it floats to the position of the through hole 6, it escapes from the guide cylinder 8 through the through hole 6 under the action of the water flow, and then the second floating ball 13 floats on the water surface and moves to the downstream of the stream along with the water flow, and sends out sound alarm or light alarm through the second alarm device under the action of the control module, so as to remind the residents, tourists, etc. around the stream.

[0033] In the above structure design, the control module controls the work of the second alarm device and does not depend on the communication construction around the monitoring point, so that the alarm signal sent out by the second floating ball 13 is reliable and the layout point of the present hydrological monitoring device can be flexibly selected.

[0034] The second floating ball 13 can send out alarm around the surrounding area during the floating process, so as to effectively expand the alarm coverage range or serve as a supplement to the alarm release.

[0035] As the liquid level in the stream rises, due to the water permeable hole 12 and the relative position of the water permeable hole 12 and the through hole 6, the second floating ball 13 easily escapes from the guide cylinder 8, so that the present hydrological monitoring device itself has high reliability.

[0036] The skilled in the art in the implementation of the scheme, the second ball 13 encapsulated with the control module can be the whole or part of the module for controlling the second alarm device. For example, when the second ball 13 is constrained in the guide cylinder 8, under the action of water flow, that is, the rolling state, the moving state and the state without the constraint of the guide cylinder 8 are completely different, so the control module can determine whether the second ball 13 is separated from the guide cylinder 8 by monitoring the displacement state of the second ball 13. At this time, the control module is the whole module for controlling the second alarm device. It can also be set to use electromagnetic induction, and the signal receiving end and the signal transmitting end of the electromagnetic induction are located on the second ball 13 and the guide cylinder 8 respectively. When the second ball 13 is separated from the guide cylinder 8 through the through hole 6 as the liquid level in the stream rises, the signal collected by the receiving end changes. At this time, according to the setting, the second alarm device can be controlled to send an alarm.

[0037] The relative positions of the through hole 6 and the water permeable hole 12 designed as above are for: the water flow enters the guide cylinder 8 through the water permeable hole 12 and flows out of the guide cylinder 8 through the through hole 6, so that the second ball 13 can be separated from the guide cylinder 8 more quickly, ensuring the sensitivity of the device. As an optimization scheme, the water permeable hole 12 is set to be strip-shaped and parallel to the height direction of the guide cylinder 8, and on the guide cylinder 8, the projection of the through hole 6 towards the side opposite to the side where it is located intersects with the water permeable hole 12. In order to avoid a large amount of silt entering through the water permeable hole 12 from burying the second ball 13, the second ball 13 is set to be located below the water permeable hole 12 only after it is stacked at the bottom of the guide cylinder 8 under the action of gravity. In order to avoid the second ball 13 from being separated from the guide cylinder 8 unnecessarily, the second ball 13 is set to be located below the through hole 6 only after it is stacked at the bottom of the guide cylinder 8 under the action of gravity.

[0038] For the purpose of wireless remote transmission of monitoring results, a communication module can be encapsulated in the second ball 13. When the second ball 13 floats to an area that can be covered by the base station signal, the communication module is used to send an alarm signal to the hydrological department or local regulatory department. More comprehensively, the second ball 13 can be provided with a positioning module for finding the second ball 13, and the real-time moving speed is transmitted by the communication module after the moving speed is monitored, so that the remote mountain torrent situation can be determined.

[0039] Further:

[0040] The control module includes an acceleration sensor for obtaining the motion of the second ball 13, and the control module determines whether the second ball 13 is separated from the guide cylinder 8 by the motion.

[0041] The above optimization scheme provides a technical scheme in which the second floating ball 13 itself has a disengagement state judgment capability, and the control module can be completely packaged in the second floating ball 13, which can simplify the installation and debugging of the device, and is a low-power consumption and low-implementation-cost technical scheme.

[0042] The number of the through holes 6 is multiple and arranged along the length direction of the guide cylinder 8, and the size of the through holes 6 decreases from the upper end to the lower end of the guide cylinder 8. The number of the second floating balls 13 is multiple and stacked in the guide cylinder 8, and the size of the second floating balls 13 decreases from the lower end to the upper end of the guide cylinder 8. The relationship between the through holes 6 and the second floating balls 13 is that any through hole 6 has a second floating ball 13 capable of passing through the through hole 6, and the largest second floating ball 13 can only be disengaged from the largest through hole 6 to the outside of the guide cylinder 8.

[0043] The above optimization scheme provides a scheme with hierarchical alarm when the water level continues to rise, and a scheme capable of releasing multiple second floating balls 13 during the rising of the water level to perform multiple route alarms. The working principle of the above scheme is that as the water level rises, when the water level rises to the first through hole 6 from bottom to top, the second floating ball 13 floating in the guide cylinder 8 and capable of passing through the first through hole 6 is disengaged from the guide cylinder 8, and as the water level continues to rise, the second floating ball 13 with a larger size is disengaged from the guide cylinder 8 through the through hole 6 above the first through hole 6. In specific implementation, the second floating balls 13 of different sizes can be provided with second alarm devices capable of outputting different sound and light alarms to prompt the escalation of the situation. Instead of setting the second floating balls 13 to be smaller and multiple second floating balls 13 capable of being laid flat in the guide cylinder 8, the purpose is to avoid the lateral extrusion between the second floating balls 13 and cause the second floating balls 13 to be stuck in the guide cylinder 8, resulting in that the second floating balls 13 cannot be smoothly guided out through the through hole 6. At the same time, the multiple second floating balls 13 stacked in the guide cylinder 8 have the possibility that the lower second floating ball 13 lifts the upper second floating ball 13, but such a situation can also make the lifted second floating ball 13 smoothly reach the height capable of guiding out the second floating ball 13, and the second floating ball 13 can also be smoothly guided out under the shaking of the lower second floating ball 13. Under this kind of use, the person skilled in the art only needs to calculate the effective height of the through hole 6 relative to the actual liquid surface according to the gravity and buoyancy of the second floating ball 13, etc. In this case, when the second floating ball 13 disengaged from the guide cylinder 8 is lifted by the lower second floating ball 13, the liquid surface in the stream does not reach the position of the through hole 6 capable of guiding out the second floating ball 13, but the installation height of the guide cylinder 8 can be determined by calculation, and even without calculation, the rising of the actual stream water level can also be represented after the second floating ball 13 is guided out, and the hydrological monitoring function is played.

[0044] As Figures 5 to 8 ,Figure 5 In the embodiment, the second floating ball 13 is composed of ball 1, ball 2, ball 3 and ball 4 from bottom to top, and the diameter of the second floating ball 13 decreases from ball 1 to ball 4; the through hole 6 is composed of hole 1, hole 2, hole 3 and hole 4 from bottom to top, and the diameter of the through hole 6 increases from hole 1 to hole 4; the relationship between the second floating ball 13 and the through hole 6 is that hole 1 can only pass ball 4, the diameter of hole 2 is greater than the diameter of ball 3 and less than the diameter of ball 2 and ball 1, the diameter of hole 3 is greater than the diameter of ball 2 and less than the diameter of ball 1, and the diameter of hole 4 is greater than the diameter of ball 1. In this way, when the liquid level rises, the second floating ball 13 is in the state of Figure 5 , the guide cylinder 8 discharges ball 4; when the liquid level continues to rise, the remaining second floating ball 13 is in the state of Figure 6 , the guide cylinder 8 discharges ball 3; when the liquid level continues to rise, the remaining second floating ball 13 is in the state of Figure 7 , the guide cylinder 8 discharges ball 2; when the liquid level continues to rise, the remaining second floating ball 13 is in the state of Figure 8 , the guide cylinder 8 discharges ball 1. That is, during the rising of the liquid level, the second floating ball 13 is released four times, and such a release mode can improve the probability of personnel obtaining an alarm, and by setting different alarm modes, the vigilance of personnel can be effectively improved.

[0045] The device frame 1 is a door-shaped frame including two vertical rods and a horizontal rod, and the guide cylinder 8 is a component part of one of the vertical rods.

[0046] The above optimization scheme provides a technical scheme that not only has a simple structure, but also facilitates reliable installation of the device at a monitoring point: the guide cylinder 8 is adapted to be a long rod, so that the guide cylinder 8 itself serves as a structural member to provide door-shaped support for the device, so that the device has two fixed points to improve the resistance to lodging.

[0047] The bottom of each vertical rod is provided with a frame body that is detachable relative to the vertical rod, the guide cylinder 8 is connected to the horizontal rod through a connecting rod 11, the connecting rod 11 and the horizontal rod are assembled in a relationship that the horizontal rod is provided with a through hole extending in the vertical direction, the connecting rod 11 passes through the horizontal rod through the through hole and can slide along the length direction of the through hole relative to the horizontal rod, the horizontal rod is further provided with a locking member 10 for fixing the connecting rod 11 to the horizontal rod, and the lower end of the connecting rod 11 is connected to the guide cylinder 8.

[0048] The above optimization scheme provides a technical scheme that can utilize the stone blocks existing around the streams in mountainous areas, fill the stone blocks in the frame body to make the frame body serve as a counterweight at the bottom of the vertical rod, and facilitate installation of the device. The detachable mode is provided to improve the transportation convenience of the device, and the connecting rod 11 is further provided to facilitate installation site selection and improve installation convenience. Figure 1After the installation of the vertical rod on the side of the first frame 3 is completed, the relative height of the bottom support surface of the first frame 3 and the bottom support surface of the second frame 4 cannot be controlled. Thus, in order to support the horizontal rod by the guide cylinder 8, the second frame 4, the guide cylinder 8 and the connecting rod 11 can form the vertical rod on the side of the second frame 4 by sliding the connecting rod 11 in the through hole. Then, the vertical rod on the side of the second frame 4 and the horizontal rod can be fixedly connected by the locking member 10, thereby forming the stable door-type device frame 1. Therefore, the length of the connecting rod 11 determines the adaptability to the height, so that the device does not need to be processed too much on the support base during installation.

[0049] The lower end of the connecting rod 11 is provided with a lower-end-opened cover 9, the cover 9 is invertedly buckled on the upper end of the guide cylinder 8, and the locking member 10 is a locking bolt.

[0050] The above optimization scheme provides a technical scheme that the device frame 1 is very convenient to install. In the above optimization scheme, Figure 1 After the bottom support of the guide cylinder 8 is completed, the connecting rod 11 embedded in the through hole is released, the connecting rod 11 moves from top to bottom, the cover 9 is invertedly buckled on the top of the guide rod, and then the connecting rod 11 is locked on the horizontal rod by the shrink bolt, thereby obtaining the stable device frame 1. In the above structure, the installation of the connecting rod 11 and the installation of the guide cylinder 8 are independent of each other and are not hindered by the already installed horizontal rod. After the connecting rod 11 cooperates with the through hole, the position of the cover 9 can be used to correct the position of the guide cylinder 8. In the process of correcting the position of the guide cylinder 8, the guide cylinder 8 can be adjusted in position very conveniently after the cover 9 is removed from the guide cylinder 8.

[0051] The hydrological module is also installed on the device frame 1, the hydrological module is used as a collection terminal of hydrological data, the hydrological module comprises a swing shaft 7, a swing rod 14 and a first floating ball 5, the swing shaft 7 is fixed on the device frame 1, the upper end of the swing rod 14 is hingedly connected with the device frame 1 through the swing shaft 7, and the first floating ball 5 is fixed on the lower end of the swing rod 14. The axis direction of the swing shaft 7 satisfies that the first floating ball 5 can swing from the side of the water-permeable hole 12 to the side of the through hole 6. The hydrological module determines the liquid level hydrological data by monitoring the swing angle of the swing rod 14.

[0052] The above scheme provides a sustainable monitoring device installation point position liquid level technical scheme, at the same time for a kind of to the reliability of monitoring result favorable scheme.According to monitoring means, similar to the above scheme, in the prior art, hydrological monitoring flow rate monitoring can use sinker, sinker is connected with trigger device by pull rope;Hydrological monitoring flow rate monitoring can use floating ball, floating ball is connected with measuring device by pull rope, the measuring device is used to measure the tension on the pull rope.And for liquid level monitoring, the prior art has the way of using measuring cylinder and floating ball, the liquid level in the measuring cylinder changes with the surrounding liquid level, by measuring the position of floating ball in the measuring cylinder, the purpose of measuring liquid level is achieved.However, this scheme needs to fix the measuring cylinder in space, when used in mountain stream level measurement, stones, wood, weeds and other things in mountain flood will directly collide with the measuring cylinder, and some floating objects will also adhere to the measuring cylinder after collision, causing the measuring form of the measuring cylinder to be not suitable for these areas.In the above preferred scheme, the first floating ball 5 rises with the rise of liquid level, due to the constraint relationship between the swing rod 14 and the swing shaft 7, the first floating ball 5 swings around the swing shaft 7 during the rising process, and the specific swing amplitude is determined by the change amount of liquid level, so this scheme can reflect the liquid level hydrological data through the swing angle of swing rod 14;In the specific structure design, the axis mode of swing shaft 7 is limited, so that: when the water permeable hole 12 is installed towards the upstream of water flow and the through hole 6 is installed towards the downstream of water flow, the axis of swing shaft 7 is perpendicular to the direction of water flow, so that after the water flow acts on the first floating ball 5, the swing shaft 7 limits the swing direction of swing rod 14, and by reasonable installation, the swing sensitivity can be controlled: generally installed in the middle of the stream width direction where the flow rate is maximum, the corresponding force can make the swing rod 14 swing very sensitively to improve the reliability and sensitivity of the device, and since there is no structure arranged underwater, and when the first floating ball 5 and swing rod 14 hook floating objects, the thrust of floating objects on the first floating ball 5 can make the swing rod 14 further swing to make the floating objects separate from the blockage of the first floating ball 5 and the like on the lower side of the first floating ball 5, and after the floating objects float away, the first floating ball 5 automatically falls back, and the sudden change of swing angle can be determined as the maximum swing angle caused by the floating object, which makes this scheme not only accurately reflect the hydrological data, but also has self-protection function;Unlike using pull rope instead of swing rod 14, the realization of the function of this scheme is not affected by flow rate and the position of first floating ball 5 (because pull rope is flexible, first floating ball 5 can move to various positions around, such as staying in water flow back bay, so the angle of pull rope or the tension thereon cannot be used to accurately reflect the measured value), so the reliability is high.When the device is upgraded, the swing rod 14 can be hollow, and the first floating ball 5 is fixed at the bottom end of the swing rod 14 by a pull rope passing through the hollow structure. In this way, because the pull rope can only pass out from the lower end of the swing rod 14, when the first floating ball 5 is attached to the bottom end of the swing rod 14 in a free state, the flexibility of the pull rope cannot make the first floating ball 5 float to a far position. At the same time, when the flow rate of the water flow increases, the tension on the pull rope increases accordingly. By using the proportional relationship between the tension and the flow rate, the flow rate can be reliably monitored. In this way, by using the swing rod 14, the situation that the floating ball may float to a position where the flow rate cannot be measured when the pull rope is used in combination with the floating ball for flow rate monitoring can be avoided.

[0053] The second floating ball 13 is also provided with a power supply module for supplying power to the second alarm device and the control module. The power supply module includes a battery, and the battery is packaged in the second floating ball 13. The cover plate can be detachably assembled on the second floating ball 13.

[0054] The above scheme is a low-cost implementation scheme, which is very suitable for areas where the device can be easily maintained.

[0055] The second floating ball 13 is also provided with a power supply module for supplying power to the second alarm device and the control module. The power supply module includes a battery, and the battery is packaged in the second floating ball 13. The cover plate can be detachably assembled on the second floating ball 13.

[0056] The above scheme is a very suitable scheme for areas where the device is not easy to maintain.

[0057] The hydrological module is also installed on the device frame 1. The hydrological module serves as a hydrological data collection terminal. The device frame 1 is also fixed with the first alarm device 2. The first alarm device 2 is in data connection with the hydrological module, and the first alarm device 2 sends out sound alarms or light alarms according to the monitoring results of the hydrological module.

[0058] The above scheme is a technical scheme that can complete local alarm in a monitoring setting point.
