Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping technology, and in particular to a hydrological surveying and mapping device for a public river basin. Background Art

[0002] River hydrological surveying and mapping is an important task, which involves the detailed measurement and recording of the river and its hydrological characteristics, aiming to provide a scientific basis for river development, regulation, water resources management, engineering construction and ecological protection. River hydrological surveying and mapping mainly measures hydrological elements such as water level, flow and water quality of the river. Therefore, when conducting hydrological surveying and mapping of the river, it is necessary to cooperate with hydrological surveying and mapping equipment to collect and summarize river information, which is conducive to subsequent development and regulation work.

[0003] A river hydrological surveying and mapping device disclosed in a patent application with reference publication number CN116698152A realizes the deformation of a linkage assembly through retained water flow, and cooperates with an adjustable baffle to limit the stroke of a guide block, thereby achieving an adjustable abnormal water level alarm without continuous power supply, and the entire process does not require continuous power supply.

[0004] At present, the water level gauges and water quality analyzers of surveying and mapping equipment are all set up separately. Affected by the changes in the water level of the river, the water quality analyzers cannot contact the river surface in real time, which easily interferes with the surveying and mapping work and reduces the accuracy of the surveying and mapping. The staff needs to make corresponding adjustments, which is time-consuming and labor-intensive and inconvenient to use. At the same time, current surveying and mapping equipment cannot complete water level measurement in a power-off state, and has great limitations. For example, the above-mentioned surveying and mapping equipment can complete water level measurement in a power-off state through structures such as liquid storage tubes. However, during actual operation, the above-mentioned surveying and mapping equipment cannot complete real-time recording of the changing state of the river water level, which is not conducive to the collection of subsequent information, and it is impossible to know the fluctuation of the river water level, which is not conducive to the stable and orderly progress of hydrological surveying and mapping work, and increases the difficulty of surveying and mapping.

The detection end completes the analysis of the river water quality, and the follow-up end is used to control the dynamic contact between the detection end and the river water area; The recording mechanism is arranged on the extension arm 3 to record the changes in the water level of the river. The recording mechanism is divided into a drawing unit, a receiving unit and an action unit. The drawing unit is connected with the follower end to complete the synchronous drawing work. The receiving unit is used to receive the drawing record of the drawing unit. The action unit is used to sense the action of the drawing unit to control the receiving unit to complete the rotation receiving operation.

[0024] Embodiment 2: Based on the water quality monitoring unit 5 provided in Embodiment 1, this embodiment provides a further technical solution of the water quality monitoring unit 5.

[0025] The detection end includes: The detection host 501 is arranged on one side of the extension arm 3 to complete the detection and analysis; The detection probe 502 is arranged below the detection host 501 and extends into the river water area, and the detection probe 502 is electrically connected to the detection host 501 to complete data transmission, and the detection host 501 is specifically a water quality analyzer host, and the detection probe 502 is specifically a water quality analyzer sensor probe; like Figure 5 , Figure 6 As shown, in the embodiment of the present invention, the follower end includes: The lifting rod 6 is slidably arranged on one side of the front end of the extension arm 3 to complete the follow-up control of the water level; The floating ball 7 is arranged at the bottom of the lifting rod 6 to dynamically sense the water level of the river. The lifting rod 6 has a circular cross section, and convex strips are symmetrically installed on both sides of the lifting rod 6. The extension arm 3 is provided with a groove that matches the convex strip, so that the lifting rod 6 can slide up and down on the extension arm 3. The lifting rod 6 is hollow in design, which is conducive to the wiring work between the detection probe 502 and the detection host 501. At the same time, in order to improve the stability of the floating ball 7, a certain amount of counterweight is added in the floating ball 7, so that the floating ball 7 can obtain stable movement; The connecting seat 8 is arranged at the bottom of the float 7 and is used to limit the detection probe 502. Specifically, the detection probe 502 is connected to the connecting seat 8 by screwing; like Figure 7 , Figure 8 As shown, the follower end also includes: The concave area 9 is provided on one side of the lifting rod 6, and a connecting rack 10 is provided at the bottom of the concave area 9; A sliding collar 11 is provided on the outside of the lifting rod 6, and the sliding collar 11 is slidably engaged with the convex strip of the lifting rod 6 to complete the guidance, and a connecting tooth plate 12 is installed on the sliding collar 11 facing the concave area 9; The control screw 13 is slidably arranged on the sliding collar 11 and is rotatably connected to the back of the connecting tooth plate 12. The control screw 13 is screwed and connected to the sliding collar 11 through a thread. A guide rod is installed on one side of the connecting tooth plate 12.

Under the setting of the follower end, the lifting rod 6 can move up and down under the restriction of the extension arm 3, and can dynamically control the float 7. Through the design of the float 7, the float 7 and the detection probe 502 fall synchronously to the river water. In the domain, the detection probe 502 is kept in contact with the river water area. At the same time, the buoyancy of the float 7 keeps the detection probe 502 dynamically at a predetermined position, thereby improving the accuracy of water quality analysis and avoiding the problem of missing collected information. With the cooperation of the water quality monitoring unit 5 and the water level monitoring unit 4, real-time hydrological mapping of the water level and water quality of the river water area can be completed. At the same time, a velocimeter can be added to the extension arm 3 as needed, so that the flow velocity of the river water area can be monitored, enriching the hydrological mapping data. The photovoltaic panel 2 is used for power supply, which can be adapted to different installation environments and take into account the effects of energy saving and environmental protection.

[0026] Embodiment 3: Based on the recording mechanism provided in Embodiment 1, this embodiment provides a further technical solution for the recording mechanism.

[0027] like Fig.12 As shown, the drawing unit includes: The drawing arm 14 is arranged on one side of the sliding collar 11 and is connected with a detachable structure; The sliding seat 15 is arranged at the front end of the drawing arm 14 and is used to connect with the receiving unit. A recording member 16, disposed at the front end of the sliding seat 15, is used to complete a dynamic drawing operation on the receiving unit; like Fig.11 As shown, the record 16 includes: The sliding frame 161 is disposed on the sliding seat 15, and a telescopic rod 162 is slidably engaged in the sliding frame 161, and the front end of the telescopic rod 162 slides through the front end of the sliding frame 161; A drawing pen 163 is detachably mounted on the front end of the telescopic rod 162 and is used for drawing and recording. The drawing pen 163 is specifically a paint pen, a marker pen or other tools capable of completing recording. The dynamic spring 164 is arranged between the telescopic rod 162 and the sliding frame 161 to dynamically control the drawing pen 163, and the dynamic spring 164 is correspondingly sleeved on the outside of the telescopic rod 162. The dynamic spring 164 pushes the drawing pen 163 to fit closely with the receiving unit to ensure the drawing effect.

[0028] like Fig. 9 , Fig.10 As shown, in an embodiment of the present invention, the receiving unit includes: The receiving chamber 17 is arranged at the front end of the extension arm 3. Sealing covers are detachably installed on both sides of the receiving chamber 17. Rotating shafts 18 are rotatably installed at the top and bottom of the receiving chamber 17. A reeling shaft 19 is detachably installed between the two rotating shafts 18. A ratchet and pawl mechanism is installed between one of the rotating shafts 18 and the receiving chamber 17 to control the reeling shaft 19 not to reverse. The release chamber 20 is arranged at one side of the receiving chamber 17, and a removable plate 21 is detachably mounted at the bottom of the release chamber 20; The release shaft 22 is rotatably mounted on the detachable plate 21 and extends into the release chamber 20. A recording roll 23 is sleeved on the outside of the release shaft 22. The release shaft 22 specifically adopts a damping shaft to provide a damping force to ensure the stable release of the recording roll 23. The recording roll 23 passes through the release chamber 20 and the receiving chamber 17 and is wound on the reel 19. The recording roll 23 specifically adopts a cloth roll, a paper roll or other tools that can complete the recording. An open area that cooperates with the recording roll 23 is provided on the side walls of the release chamber 20 and the receiving chamber 17. A guide shaft is rotatably mounted in the open area to guide the recording roll 23 so that the recording roll 23 can pass smoothly. The receiving unit also includes: The open slideway 24 is opened through the middle of the front end of the receiving chamber 17, and the open slideway 24 is slidably engaged with the sliding seat 15, and the recording member 16 extends into the receiving chamber 17 through the open slideway 24; A one-way bearing 25 is arranged on the top of one of the rotating shafts 18. A driving gear 26 is installed on the one-way bearing 25. The one-way bearing 25 controls the rotating shaft 18 to complete the one-way limited rotation. The one-way bearing 25 is arranged in cooperation with the ratchet and pawl mechanism so that the winding shaft 19 completes the rotation in a predetermined direction. like Fig.13 , Fig.14 As shown, in the embodiment of the present invention, the action unit includes: Track 27, provided on one side of the top of receiving chamber 17 for guiding work; The driving rack 28 is slidably engaged on the track 27 and meshes with the driving gear 26, and the driving control of the winding shaft 19 is completed by meshing the driving rack 28 with the driving gear 26; The action member 29 is installed on the drawing unit. Specifically, the action member 29 is connected to the sliding seat 15 through a bracket. An undulating trajectory line 30 is arranged on the side of the action member 29 facing the drawing unit. The undulating trajectory line 30 is composed of a plurality of trapezoidal bodies 301 arranged side by side in sequence. The size and number of the trapezoidal bodies 301 follow the change in the amount of water in the river channel to complete the adaptation increase and decrease work, so as to ensure the stable progress of the triggering work. The edge of each trapezoidal body 301 adopts an arc transition, so that the undulating trajectory line 30 forms a continuous wave groove. Both sides of each trapezoidal body 301 are provided with inclined surfaces 302 for completing the guidance control. The dynamic transmission of the drawing unit action is completed through the undulating trajectory line 30. When the driving rack 28 is pushed by the undulating trajectory line 30, the one-way bearing 25 is locked to complete the power transmission. When the driving rack 28 is reset by the reset spring 34, the one-way bearing 25 is unlocked and no power transmission is performed. An accelerator, arranged on the receiving chamber 17, is used to sense the dynamic movement of the undulating trajectory line 30, and triggers the driving rack 28 to complete the movement triggering through the accelerator; It is worth noting that when recording the change of the water level in the river channel: by providing a recording mechanism, when recording is required, it is only necessary to operate the control screw 13 to drive the connecting tooth plate 12 to move and mesh with the connecting rack 10, so as to complete the power connection, and when the subsequent lifting rod 6 follows the floating ball 7 to move up and down dynamically, it drives the sliding collar 11 and the drawing unit to complete the synchronous action, so as to complete the power transmission, ensure the stable operation of the recording mechanism, and complete the recording of the change of the water level in the river channel; When drawing and recording is performed specifically: by providing a drawing unit, the drawing arm 14 and the sliding seat 15 move synchronously with the lifting rod 6. When the lifting rod 6 senses a change in water level, the drawing arm 14, the sliding seat 15 and the recording member 16 move synchronously with it, and the dynamic change of the water level is recorded on the recording volume 23 of the receiving unit via the recording member 16, thereby completing the dynamic recording of the river water level. In addition, the recording member 16 adopts the design of a telescopic rod 162 and a sliding frame 161. Under the push of a dynamic spring 164, the drawing pen 163 is always in contact with the recording volume 23 of the receiving unit, thereby improving the stability of drawing and recording; When drawing and receiving specifically: a receiving unit is provided, in order to improve the intuitive effect of drawing and recording water level changes, when the drawing arm 14 moves up and down synchronously, the action member 29 also moves with it. Since the action member 29 is provided with an undulating trajectory line 30, the sensing shaft 39 is pushed by the reset spring 34 to always fit with the undulating trajectory line 30. When the action member 29 moves up, the sensing shaft 39 moves up under the guidance of the inclined surface 302 of the trapezoidal body 301 of the undulating trajectory line 30, so that the acceleration member and the driving rack 28 move forward. Since the driving rack 28 is meshed with the driving gear 26, the driving gear 26 is locked under the one-way bearing 25. 26, the rotating shaft 18 and the winding shaft 19 rotate, and stretch the recording roll 23, so that the contact surface of the recording roll 23 and the recording member 16 completes the follow-up switching, which is beneficial to the subsequent observation and recording data. Later, under the pull of the reset spring 34, when the sensing shaft 39 is separated from the highest point of the single trapezoidal body 301, the sensing shaft 39 moves toward the connection point of the adjacent trapezoidal body 301, and pulls the driving rack 28 to reset and move. Under this action, the one-way bearing 25 is unlocked, and the driving rack 28 does not move the winding shaft 19. Under the reciprocating drive of the driving rack 28 and the driving gear 26, the winding shaft 19 can be driven to rotate, which is beneficial to the recording work. Similarly, when the actuating member 29 moves downward, since inclined surfaces 302 are provided on both sides of the trapezoidal body 301 of the undulating trajectory line 30, when the water level drops, the sensing axis 39 and the accelerator can also be triggered to move, so that the driving rack 28 moves forward. With such a design, when the water level in the river fluctuates up and down, the actuating member 29 can trigger the winding shaft 19 to rotate continuously in a predetermined direction, thereby improving the recording accuracy and avoiding the problem of confusion in recorded data.

[0029] like Fig.15 As shown, in an embodiment of the present invention, the acceleration component includes: A first rack 31 is arranged at one side of the receiving chamber 17. A moving area 32 is formed through the first rack 31. A moving block 33 is slidably engaged in the moving area 32. A return spring 34 is installed between the moving block 33 and the moving area 32. The second rack 35 is arranged at the rear of the driving rack 28; A first fixing frame 36 is arranged on the shifting block 33, and an acceleration gear 37 is rotatably mounted on the first fixing frame 36, and the acceleration gear 37 is meshed and arranged between the first rack 31 and the second rack 35; The second fixing frame 38 is arranged on one side of the first fixing frame 36, and a sensing shaft 39 is rotatably mounted on the second fixing frame 38. The sensing shaft 39 is in close contact with the undulating trajectory line 30, and the sensing shaft 39 is pushed by the reset spring 34 to move in close contact with the undulating trajectory line 30. The one-way triggering action of the reeling shaft 19 of the receiving unit is completed by the close contact between the sensing shaft 39 and the undulating trajectory line 30; It is worth mentioning that in order to increase the extension of the rotation amount of the winding shaft 19 by the driving rack 28, an acceleration member is provided. When the sensing shaft 39 is squeezed and moved by the trapezoidal body 301, the No. 1 fixing frame 36 and the acceleration gear 37 are first pushed to move via the No. 2 fixing frame 38. Since the acceleration gear 37 is meshed with the No. 1 rack 31 and the No. 2 rack 35, a rotation amount is superimposed on the amount of the acceleration gear 37 pushed forward by the No. 2 fixing frame 38, so that the formation of the No. 2 rack 35 is extended, and the movement amount of the driving rack 28 connected to the No. 2 rack 35 is extended, so that the winding shaft 19 can obtain stable rotation, avoid the problem of mutual interference between adjacent recorded data, facilitate subsequent observation of the data, and improve the surveying and mapping effect.

[0030] The present invention provides a hydrological surveying and mapping device for a public river basin, and the specific working principle is as follows: first, a column 1 is fixed on the bank of the river basin, and then a photovoltaic panel 2 is assembled on the top of the column 1, and then the photovoltaic panel 2 is electrically connected to the photovoltaic controller, waiting for subsequent wiring to the water level monitoring unit 4 and the water quality monitoring unit 5 to complete power supply, and then the position of the extension arm 3 on the column 1 is adjusted according to the height of the river, and then the extension arm 3 is fixed to the column 1 through a clamp, and then the water level monitoring unit 4 is assembled on the extension arm 3 to complete water level monitoring.

At the same time, a recording mechanism is added, which follows the water quality monitoring unit 5 to complete the follow-up cooperation. The water quality monitoring unit 5 can sense the change of river water level during the water quality monitoring. With the assistance of the drawing unit and the action unit, the change of river water level can be sensed and triggered, and the real-time recording is completed through the receiving unit. Dynamic continuous drawing operations can be completed in the absence of electricity, avoiding the problem of missing river water level changes when electronic equipment such as the water level monitoring unit 4 fails, enriching the drawing data, improving the accuracy of river hydrological drawing, reducing the error rate, and providing a guarantee for river water level surveying and mapping.
