Description

TECHNICAL FIELD

[0001] The present application relates to the field of water body monitoring, in particular to a water quality monitoring mechanism. BACKGROUND

[0002] China vigorously promotes the construction of water quality online monitoring stations in the field of water quality monitoring of water systems. Important links such as key river basins, urban water supply, and urban drainage have successively constructed water quality online monitoring stations. The online water quality monitoring process is based on water quality online monitoring instruments and integrated systems as carriers. Real-time monitoring data is uploaded to the designated platform, so that the operator or user can observe the terminal device or mobile phone APP to learn the real-time water quality data of the corresponding river.

[0003] The existing water quality monitoring mechanism needs to be determined according to the local hydrological and geological conditions, meet the basic technical requirements, and ensure the stability of the monitoring system, the representativeness of the water sample, and the convenience of maintenance. According to different needs, different monitoring structures are selected to be arranged at the bottom of the water flow, the top of the water flow, or the middle of the water flow to monitor the water quality.

[0004] Arranging the monitoring structure at the bottom of the water flow or the top of the water flow is relatively simple. For example, the monitoring structure can be directly driven into the riverbed bottom, and the monitoring structure can be fixed on the water surface by using a floating device. The construction difficulty is relatively large in the middle of the water flow. The existing method is to arrange a rod on the shore of the water flow. The rod monitoring mechanism is inserted into the area of the required water depth to detect the water quality of the depth. Although this method can obtain real-time water flow information, a large amount of floating objects will be moved when the water flow flows. The floating objects will cause a large impact on the rod. Once the large-volume and heavy floating objects such as logs impact the rod in a high-flow state, the rod will be directly bent or even broken, so that the monitoring structure on the rod cannot normally monitor the water quality, and even is damaged. It needs to be maintained by artificial maintenance, which is relatively troublesome. SUMMARY

[0037] In order to make the embodiments of the present application, all belong to the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application.

Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts, the number of relative importance or implicitly indicated technical features. Therefore, the features with "first", "second" can be explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0039] The existing structure inserted into the middle section of the water body is mostly to insert a rod into the water bottom. Although it can indeed monitor the water quality of the water body at the required depth, once it encounters a period of fast flow such as the rainy season, the debris carried in the high-speed flow will cause a great impact on the rod, causing the rod to bend or even break, and the sensors and other monitoring structures fixed on the rod will also be damaged. The operator needs to maintain the entire structure, and during the maintenance process, the water body cannot be monitored, and in fact, the maintenance process in the middle section of the water body is relatively difficult. In order to solve the above technical problems, the technical scheme is as follows:

[0040] Referring to Figures 1-11 A water quality monitoring mechanism, comprising: a plurality of pre-buried pieces 1 pre-buried in the bottom of the water flow; a matching structure 2 movably clamped in the pre-buried piece 1; a chassis 3 for fixing the matching structure 2, the chassis 3 is provided with an anchor hook structure 31; a lower frame 4 fixed to the top of the chassis 3, the inner side of the lower frame 4 is provided with a buoyancy assembly 41; a middle frame 5 locked on the top of the lower frame 4, the inside of the middle frame 5 is provided with a plurality of reversing motors 51; an upper frame 6 locked on the top of the middle frame 5, the upper frame 6 comprises a rotating plate 61 connected with the reversing motor 51, an adjusting motor 62 locked on the rotating plate 61, an adjusting cable 63 wound on the adjusting motor 62, and a monitoring assembly 64 locked on the adjusting cable 63.

[0041] The embodiment tests the water quality in the middle of the water flow, so it is not appropriate to directly set the monitoring mechanism at the top of the water flow or the bottom of the water flow, but to set the monitoring assembly 64 in the middle section of the water flow. Since the monitoring assembly 64 is easily fluctuated due to the fluctuation of the water flow if it is set from the top of the water surface, it is difficult to maintain balance, so in this embodiment, the monitoring assembly 64 is indirectly set from the bottom of the water surface.

[0042] In this embodiment, first, the pre-buried piece 1 is driven into the bottom of the water flow, for example, when the mechanism is set in an inland river, the pre-buried piece 1 is driven into the bottom of the riverbed, then the matching structure 2 of the entire mechanism is matched with the pre-buried piece 1, thereby completing the fixed connection of the entire mechanism.

[0043] In the whole process of making the mechanism, first, the bottom frame 3 is welded, then the lower frame 4 is welded, the welding seam between the lower frame 4 and the bottom frame 3 is tight, which can greatly avoid water entering the inside of the buoyancy assembly 41 in the lower frame 4, then the middle frame 5 is welded, the welding seam between the middle frame 5 and the lower frame 4 is tight, which makes the reversing motor 51 sealed inside, finally, the whole upper frame 6 is welded, which provides a load mechanism for each structure on the upper frame 6, and in the whole prefabrication process, the gaps between each frame are minimized to improve the water avoidance performance of the whole mechanism, so as to avoid the phenomenon of water leakage and short circuit of electrical components after long-term use.

[0044] After the above installation process is completed, the monitoring assembly 64 needs to be arranged. Since the water quality of water flow at different depths needs to be monitored, monitoring assemblies 64 at different heights need to be arranged, and the height adjustment of the monitoring assembly 64 is achieved by adjusting the forward or reverse rotation of the motor 62, so that the adjusting cable 63 rises or falls, and the monitoring assembly 64 on the adjusting cable 63 rises or falls.

[0045] Through the above adjustable means, a plurality of monitoring assemblies 64 can be arranged in the same water quality monitoring structure, for example, starting from the bottom of the water, the first adjusting cable 63 is first extended by 2m in length, the second adjusting cable 63 is then extended by 3m in length, and the third adjusting cable 63 is extended by 4m in length, so that different adjusting cables 63 are located at different heights to monitor the water quality of water bodies at different depths.

[0046] In the application stage, for example, when the water flows from the left end to the right end, the height of the monitoring assembly 64 located at the leftmost end is the lowest, and the length of the monitoring assembly 64 increases from left to right, and the height of the adjusting cable 63 continuously increases, so that the water quality at different heights can be measured from low to high along the direction of the water flow.

[0047] Although the arrangement of the monitoring assembly 64 extending upward from the bottom of the water flow avoids the influence of impurities in the water body on the monitoring assembly 64, but the branches, garbage and other impurities in the water body will be blocked by the adjusting cable 63, once they cannot pass through the adjusting cable 63 quickly, they may accumulate near the adjusting cable 63, until the adjusting cable 63 is pulled off or even broken, therefore, in order to avoid the accumulation of impurities near the adjusting cable 63, the reversing motor 51 is arranged in the middle frame 5, which will continuously drive the rotating plate 61 to rotate during rotation, and further drive the adjusting motor 62, the adjusting cable 63 and the monitoring assembly 64 on the rotating plate 61 to rotate, so that the impurities such as branches and large garbage wrapped around the monitoring assembly 64 in the water flow are taken away by the centrifugal force of the rotating adjusting cable 63, so as to separate from the adjusting cable 63, and the impurities flowing in the water flow do not affect the adjusting cable 63 in the middle of the water flow.

[0048] And since all the adjusting ropes 63 are located on the same straight line, after the adjusting rope 63 at the front end rotates to divert the sundries, the sundries will flow to other areas and will not be wound on the subsequent adjusting ropes 63, so there is no need to worry about the problem of continuous and multiple winding.

[0049] In fact, the embedded part 1 is not in a fixed connection with the multiple frames. During the replacement or maintenance of the entire water quality monitoring system, the entire frame structure can be easily suspended by the buoyancy assembly 41. Specifically, the buoyancy assembly 41 is inflated, the entire monitoring mechanism is subjected to the buoyancy force to overcome its own gravity, can float in the water, and then the anchor hook structure 31 is extended and hooked to the bottom of the water to position the entire monitoring mechanism. The clamping relationship between the cooperation structure 2 and the embedded part 1 is released, so that the entire monitoring mechanism is completely free from restraint, rapidly floats to the water surface under the buoyancy state caused by the buoyancy assembly 41, and is convenient for the staff to recycle and replace or maintain. Compared with the conventional water quality monitoring structure which is difficult to recycle after installation, it is more convenient.

[0050] During the rainy season or during the heavy rain period, the water flow of the entire river or river surface will suddenly increase, and the flow rate of the river will also suddenly increase, and the accompanying situation is that the flow rate of the sundries carried in the river also increases. Once the speed of the sundries increases, its kinetic energy will also increase, which is easy to cause damage to the entire mechanism. In order to avoid the above situation, the water quality monitoring mechanism in the embodiment further comprises a speed measurement mechanism 7 extending from the embedded part 1 to the water flow direction, and the speed measurement mechanism 7 is at least 5m away from the nearest adjacent embedded part 1. Specifically, the speed measurement mechanism 7 is 20m away from the nearest adjacent embedded part 1. After detecting the sudden increase in the flow rate of the water flow, the adjusting motor 62 drives the adjusting rope 63 to be recovered, so that the adjusting rope 63 and the monitoring assembly 64 on the adjusting rope 63 are not easily damaged. 20m is a relatively safe distance, which can reduce the height of the adjusting rope 63 and the monitoring assembly 64, so that they are not touched by the sundries in the water. If it is less than 20m, the height of the adjusting rope 63 is not enough, and the adjusting rope 63 and the monitoring assembly 64 are still at risk of being hit. If it is longer than 20m, the installation cost will be greatly increased, and the stability is difficult to guarantee.

[0051] The specific composition of the speed measuring mechanism 7 is that the speed measuring mechanism 7 includes an extension arm 71 welded outside the embedded part 1 and close to the bottom of the water flow, a sling 72 nailed on the extension arm 71, and a flow rate sensor 73 locked at the top of the sling 72. The extension arm 71 is a stainless steel structure, which is directly nailed on the river bottom through steel nails and does not need to be removed after being fixed. The spacing between the steel nails is 60 cm, which can make the extension arm 71 be fixed more stably and not easy to collapse. The sling 72 is also made of stainless steel structure to avoid rust. The flow rate sensor 73 is used to sense the flow rate of the water flow, so as to send signals to the adjusting motor 62 in time for feedback adjustment, so that the adjusting motor 62 can act in time.

[0052] The embedded part 1 is prefabricated in the factory. In order to realize the cooperation between the embedded part 1 and the cooperating structure 2, the embedded part 1 includes a solid seat 12 with an installation groove 11 inside. The inside of the installation groove 11 extends to the solid part of the solid seat 12 with a plurality of cooperating grooves 13. The cooperating grooves 13 are arranged on different planes and partially overlap in height. The solid seat 12 is filled with metal or concrete so that the entire embedded part 1 has enough weight to sink to the bottom of the water. The installation groove 11 is used to accommodate a plurality of cooperating structures 2. The number of cooperating structures 2 and installation grooves 11 can depend on the area covered by the monitoring structure. If the entire monitoring mechanism covers a large area, the number of cooperating structures 2 and installation grooves 11 should be increased accordingly. If the entire monitoring mechanism covers a small area, the number of cooperating structures 2 and installation grooves 11 can be reduced accordingly. The structure that specifically forms the limiting effect with the cooperating structure 2 is the cooperating groove 13. The cooperating groove 13 and the cooperating structure 2 are movably connected to achieve the purpose of movably connecting the embedded part 1 and the cooperating structure 2.

[0053] As mentioned above, the cooperating structure 2 and the embedded part 1 can have a cooperating structure. Specifically, the cooperating structure 2 includes a push rod motor 21, a pressure cylinder 22 nested outside the output shaft of the push rod motor 21, the pressure cylinder 22 is filled with fluid, a plurality of arc handles 23 arranged at the bottom of the pressure cylinder 22, and the arrangement position of the arc handle 23 corresponds to the cooperating groove 13. When the arc handle 23 needs to cooperate with the cooperating groove 13, the push rod motor 21 is pushed out. The push rod motor 21 directly presses the pressure cylinder 22, so that the liquid in the pressure cylinder 22 flows out, and the liquid pushes the arc handle 23 out, so that the arc handle 23 is clamped into the cooperating groove 13, and the position of the entire cooperating structure 2 and various mechanical structures on the cooperating structure 2 is fixed and positioned on the embedded part 1.

[0054] However, the matching structure 2 and the embedded part 1 are detachable, that is, when the whole mechanism needs to float to the water surface, the matching structure 2 needs to be separated from the embedded part 1, and in the above mechanism description, although the extension and retraction of the push rod motor 21 can cause the pressure change of the liquid in the pressure cylinder 22, when the push rod motor 21 retracts, it is obviously impossible to reset the position of the arc handle 23, so that the matching structure 2 cannot be separated from the embedded part 1, so in order to separate the two, the arc handle 23 also switches state when the push rod motor 21 extends and retracts, so the arc handle 23 includes an arc-shaped inner handle 231 fixed inside the bottom of the pressure cylinder 22, a flow-through opening 232 opened above the arc-shaped inner handle 231, a connecting block 233 slidingly connected to one side of the arc-shaped inner handle 231 pointing to the matching groove 13, a blocking block 234 provided on the other side of the connecting block 233, and a spring 235 connected between the blocking block 234 and the arc-shaped inner handle 231, that is, in the state that the push rod motor 21 is not pressed, the blocking block 234 is located in the arc-shaped inner handle 231, and when the push rod motor 21 is pressed, the flow-through opening 232 has pressure liquid flowing in, so that the connecting block 233 and the blocking block 234 slide out, the spring 235 is stretched, the blocking block 234 is embedded in the matching groove 13, and the clamping between the matching structure 2 and the embedded part 1 is completed, and when the pressure of the push rod motor 21 disappears, due to the reset of the spring 235, the connecting block 233 and the blocking block 234 will return to the original position, so that the matching relationship between the blocking block 234 and the matching groove 13 disappears.

[0055] In this embodiment, the setting position of the arc-shaped inner handle 231 is distributed in an annular array along the whole pressure cylinder 22, and correspondingly, the matching grooves 13 are also distributed in an annular array inside the solid seat 12, so that the restriction force in each direction can be more uniform, and the installation in any direction can resist the impact force of the water flow on the connection between the matching structure 2 and the embedded part 1.

[0056] The design of the connecting block 233 is that after the blocking block 234 is pushed out, the pressure liquid entering the flow-through opening 232 will not leak out of the arc-shaped inner handle 231, the connecting block 233 can be extended inside the blocking block 234, and the two are integrated structures, which are pushed out together and retracted together.

[0057] At the same time, in order to ensure the strength of the connection, the diameters of the connecting block 233 and the blocking block 234 can be appropriately adjusted according to the local water flow conditions, for example, the setting position is at the upstream stage of the river, at this time, the flow rate of the water flow is large, the impact force of the water flow is large, and the flow rate of the carried sundries is also fast, so at this time, the diameters of the connecting block 233 and the blocking block 234 need to be appropriately increased to ensure that enough matching force can be provided between the matching structure 2 and the embedded part 1.

[0058] In order to avoid other sundries in the water flow from entering the gap between the fitting structure 2 and the embedded part 1, the outer side of the pressure cylinder 22 is sleeved with a sealing cover 24, which is tightly attached to the solid seat 12 when the pressure cylinder 22 is clamped to the installation groove 11. The sealing cover 24 does not need to be manually locked. When the position of the arc handle 23 corresponds to the arc-shaped inner handle 231, the sealing cover 24 is just matched with the top of the solid seat 12, sealing the space between the solid seat 12 and the outside, so as to achieve the purpose of sealing when the fitting structure 2 is matched with the embedded part 1, and separating when the fitting structure 2 is separated from the embedded part 1. If manual locking is used, the sealing cover 24 cannot be automatically released when the fitting structure 2 is remotely separated from the embedded part 1.

[0059] When it is necessary to make the fitting structure 2 and the structure thereon float up, the buoyancy needs to be greater than the gravity. Therefore, in order to automatically complete the floating action, the floating assembly 41 includes a gas bag 411 arranged inside the lower frame 4, a gas pump 412 communicated with the gas bag 411, a plurality of gas bags 413 arranged in a rectangular shape outside the lower frame 4, a gas filling pipeline 414 connected between the gas pump 412 and the gas bags 413, and the control end of the gas pump 412 is electrically connected with the control end of the push rod motor 21. It needs to be emphasized that the action sequence of the gas pump 412 is superior to that of the push rod motor 21, that is, first, the gas pump 412 is used to inflate the gas filling pipeline 414 and the gas bags 413, so that the gas bags 413 are inflated, and the gas bags 413 bring great buoyancy to the entire mechanism to overcome the gravity of the mechanism itself. After the inflation process is completed, the push rod motor 21 is retracted to release the cooperation between the arc handle 23 and the fitting groove 13. At this time, the entire mechanism floats up under the action of the buoyancy, and the complete automatic floating action is completed.

[0060] Since the entire mechanism is arranged in the water, the floating assembly 41 is also arranged in the water, so the floating assembly 41 cannot draw air from the atmosphere. Therefore, the gas bag 411 is arranged in the floating assembly 41. In use, the gas pump 412 draws the gas in the gas bag 411 to inflate the gas bags 413. After floating up, the gas bag 411 can be re-inflated. In order to reduce the volume ratio of the mechanism as much as possible, the shape of the gas bag 411 can be an irregular structure, which can occupy the internal space of the mechanism as much as possible without affecting the action of the structure inside the mechanism, and at the same time, it can store slightly excessive gas as much as possible to keep the gas bags 413 at a sufficient pressure.

[0061] In order to maintain the pressure of the gas bags 413, in this embodiment, the gas bags 413 are double-layered, and the outer part of the gas bags 413 is coated with a layer of glue to ensure the pressure maintaining capacity of the gas bags 413, so as to avoid the gas bags 413 from falling to the bottom of the water after floating up to half.

[0062] When the whole mechanism floats upward under the action of buoyancy, at this time, although the floating action is completed, the floating direction is uncontrollable, and it will drift to other positions under the action of water flow. Therefore, in order to position its position, so that it can be at the predetermined point that the staff can recover after floating, the anchor hook structure 31 comprises an inner mounting frame 311 fixed in the chassis 3, a winch 312 movably connected inside the inner mounting frame 311, a rotary motor 313 inserted at one end of the axial direction of the winch 312, a rope 314 wound on the winch 312, and a boat anchor 315 tied to the outermost end of the rope 314. The control end of the rotary motor 313 is electrically connected with the control end of the push rod motor 21. The output of the rotary motor 313 is synchronized with the push rod motor 21, that is, when the push rod motor 21 retracts, the cooperation between the arc handle 23 and the matching groove 13 is released, the rotary motor 313 immediately rotates the winch 312, the boat anchor 315 is lowered through the rope 314, and the boat anchor 315 sinks and inserts into the soil at the bottom of the water. After the boat anchor 315 is fixed, the air pump 412 inflates immediately. The whole process is in the order of: push rod motor 21 retraction-rotary motor 313 forward rotation-air pump 412 inflation, so as to complete the disengagement, floating and positioning effect of the whole mechanism, so that the floating of the whole mechanism is in the controllable range of the recovery personnel, facilitating recovery and next installation.

[0063] As mentioned above, the adjusting motor 62 needs to drive the monitoring assembly 64 to move, and when the speed measuring mechanism 7 detects that a large flow rate of water flow arrives, the adjusting motor 62 needs to respond quickly. Therefore, in order to avoid the interference of water algae and other mayfly parasites in the water body, the upper frame 6 further comprises a water curtain assembly 65 arranged at the intersection of the diagonals of the four adjusting motors 62. The water curtain assembly 65 comprises a water pump 651, and a flushing pipe 652 connected with the water pump 651 and pointing to the four adjusting motors 62. The water pump 651 can extract water in the water flow to flush the area near the adjusting motor 62 through the flushing pipe 652, so that the water algae and other mayfly parasites cannot stay and avoid attaching to the adjusting motor 62 and the adjusting cable 63.

[0064] In order to reduce energy consumption and reduce the loss of the water pump 651, a time control circuit can be arranged in the water pump 651 to start and stop at intervals, for example, the water pump 651 can be started at intervals at a time period of 5 minutes or 8 minutes to ensure the flushing efficiency and reduce energy consumption.

[0065] When laying the power line, the cable can be laid along the continental shelf along the bottom of the water, and then connected with each electrical appliance on the mechanism to ensure normal power supply. Since it is a special cable for the bottom of the water, there is no need to worry about the problem of electric leakage.

[0066] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
