Description

Technical Field

[0001] This invention relates to the field of water level early warning devices, specifically a water level early warning device for hydrological monitoring. Background Technology

[0002] A radar level gauge, also known as a water level radar, is an electronic device that uses electromagnetic waves to detect targets. It is mainly used for water conservancy monitoring, sewage treatment, and flood warning. Its main measurement principle is that the radar level sensing antenna emits radar pulses, and the antenna receives the pulses reflected back from the water surface and records the time T. Since the propagation speed C of electromagnetic waves is a constant, the distance D to the water surface can be obtained. Its measurement accuracy is not affected by external conditions, natural environment, water body, etc. At the same time, the internal system is equipped with wind and wave filtering function, which can effectively eliminate the error caused by wind and waves to water level measurement. It has a large measurement range and is an ideal water level measurement device.

[0003] The installation environment for radar level gauges must avoid obstacles or floating objects, and must be perpendicular to the water surface, with the radar waves fully covering the water surface. Therefore, the traditional installation method involves a support frame formed by a column and a crossarm. The radar level gauge is installed at the end of the crossarm, the column is fixed to the bank, and the crossarm supports the radar level gauge, allowing it to float vertically above the water surface. However, crossarms are mostly of fixed length, resulting in a fixed distance the radar level gauge extends beyond the bank. In reality, the distance between the water surface and the bank varies depending on the measurement requirements, making a fixed-length crossarm unsuitable for different measurement environments. Furthermore, crossarms are mostly bolted to the column. When the radar level gauge malfunctions and requires maintenance, personnel must climb to a higher position to dismantle the crossarm or detach the connection between the column and the ground. Both methods are time-consuming and require multiple people working together, consuming significant manpower and resources while exhibiting low maintenance efficiency. Therefore, this paper proposes a hydrological monitoring water level early warning device. Summary of the Invention

[0004] The purpose of this invention is to provide a hydrological monitoring water level early warning device in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydrological detection water level early warning device, comprising a support assembly consisting of a mounting base and a column, and a cross frame assembly. The column is fixed to the top of the mounting base. The cross frame assembly includes a fixing unit, a rotating unit, and an extension unit. One end of the extension unit is provided with a clamping assembly. The clamping assembly is used to fix a radar water level gauge, and the cross frame assembly is used to provide support for the radar water level gauge.

The other end of the telescopic top rod is flush with the other end face of the rotating arm. The moving telescopic top rod protrudes to the other end face of the rotating arm and is pressed to achieve separation from the self-locking slot.

[0033] The pressure block is slidably connected to the inner side of the reset slide groove and is fixed perpendicularly to the horizontal through groove. The third spring is disposed on the inner side of the reset slide groove, with one end of the third spring connected to the pressure block and the other end attached to the inner wall end face of the reset slide groove but not connected.

[0040] As a further embodiment of the present invention: a top cap is fixedly connected to the top of the column, and a rotating groove for inserting the top of the threaded rod is provided on the top of the inner wall of the top cap.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. By setting up a crossbeam assembly and a drive assembly, when the drive assembly provides a downward tilting force to the crossbeam assembly, the crossbeam assembly can first retract and then rotate downward, bringing the radar level gauge closer to the ground and the column. At this time, maintenance personnel can directly stand on the ground to inspect and replace the radar level gauge. When the drive assembly provides an upward tilting force to the crossbeam assembly, the crossbeam assembly can first rotate upward and then extend, thus easily placing the radar level gauge above the water surface. The maintenance operation of the radar level gauge can be realized through the cooperation of the above multiple parts, without the need for climbing or multiple people to work together. Its operation is simple and convenient.

[0043] 2. By setting an unlocking component, when the rotating unit and the extension unit are facing downwards, the unlocking component presses against the clamping component, causing the clamping component to release its self-locking mechanism. This allows for convenient disassembly and assembly of the radar level gauge. When the rotating unit rotates to a horizontal position, the unlocking component releases its pressure on the clamping component, at which point the clamping component achieves self-locking reinforcement, ensuring the stability of the radar level gauge in daily use. The cooperation of these multiple components makes the disassembly and assembly of the radar level gauge more convenient, effectively improving the efficiency of radar level gauge disassembly and assembly.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0067] Please see Figures 1 to 13 In this embodiment of the invention, a hydrological detection water level early warning device includes a support assembly 1 consisting of a mounting base 101 and a column 102, and a cross frame assembly 2. The column 102 is fixed to the top of the mounting base 101. The cross frame assembly 2 includes a fixing unit 201, a rotating unit 202, and an extension unit 203. One end of the extension unit 203 is provided with a clamping assembly 3, which is used to fix a radar water level gauge 4. The cross frame assembly 2 is used to provide support for the radar water level gauge 4.

[0068] The fixed unit 201 is used to provide rotation support for the rotating unit 202. The rotation of the rotating unit 202 is used to make the radar level gauge 4 rotate closer to the ground, so that maintenance personnel can easily inspect and replace the radar level gauge 4.

[0069] The extension unit 203 is slidably installed inside the rotating unit 202. The movable extension unit 203 is used to adjust the distance of the radar level gauge 4 away from the shore.

[0070] The rotating unit 202 is also equipped with an unlocking component 5. The unlocking component 5 is used to unlock the clamping component 3 in the locked state, so that the clamping component 3 that rotates close to the ground can be opened, thereby realizing the disassembly and assembly of the radar level gauge 4.

[0071] The interior of the column 102 is also provided with a drive assembly 6 that extends to the outside of the column 102 and is connected to the extension unit 203. The drive assembly 6 is located to provide power for the rotation of the rotating unit 202 and the extension movement of the extension unit 203.

[0072] In this embodiment: when the rotating unit 202 and the extending unit 203 rotate downward as a whole, the clamping component 3 is close to the ground and can be easily opened and closed. At this time, maintenance personnel can directly stand on the ground to install the radar level gauge 4 inside the clamping component 3 or remove the radar level gauge 4 without climbing or multiple people working together. Its operation is simple and convenient.

[0073] After the radar level gauge 4 is repaired and replaced, the drive assembly 6 is operated using external tools. The drive assembly 6 provides power to the rotation unit 202 and the extension unit 203. The operation of the rotation unit 202 and the extension unit 203 is as follows:

[0074] At the beginning, the rotating unit 202 rotates, and the extension unit 203 rotates synchronously with the rotating unit 202. The extension unit 203 and the rotating unit 202 remain relatively stationary. This operation causes the radar level gauge 4 to be lifted up. At the same time, during this process, the unlocking component 5 separates from the clamping component 3, and the clamping component 3 achieves self-locking, thus achieving stable installation of the radar level gauge 4.

[0075] When the rotating unit 202 rotates to a horizontal state, the driving component 6 continues to run to push the extension unit 203 to extend and move. At this time, the rotating unit 202 maintains a stable horizontal state. By extending the extension unit 203, the radar level gauge 4 can be moved to the water surface, thus completing the installation of the radar level gauge 4. Furthermore, by changing the extension length of the extension unit 203, the position of the radar level gauge 4 can be adapted to different installation environments, improving the applicability of the device.

[0076] Please refer to this carefully. Figures 1 to 11 The fixing unit 201 includes an arc-shaped mounting plate 2011, an n-shaped connecting seat 2012, a rotating hole 2013, and a first limiting rail groove 2014;

[0077] The arc-shaped mounting plate 2011 is attached to the outside of the column 102 and fixedly connected to the column 102 by bolts. The n-type connecting seat 2012 is fixed to the end of the arc-shaped mounting plate 2011 away from the column 102. The rotating hole 2013 and the first limiting groove 2014 are symmetrically opened on both sides of the n-type connecting seat 2012. The first limiting groove 2014 is distributed on the outside of the rotating hole 2013.

[0078] The rotating unit 202 includes a rotating arm 2021, a rotating shaft 2022, a T-shaped slide 2023, a first locking rod 2026, a first spring piece 2027, and a fixed stop block 2028;

[0079] The rotating shaft 2022 is symmetrically fixed on both sides of one end of the rotating arm 2021. The rotating shaft 2022 is rotatably connected to the inside of the rotating hole 2013. The rotating arm 2021 is rotatably connected to the inside of the n-type connecting seat 2012 through the rotating shaft 2022.

[0080] The T-shaped slide groove 2023 is opened inside the rotating arm 2021 and passes through both ends and the bottom of the rotating arm 2021. Horizontal moving grooves 2025 are opened on both sides of the part of the rotating arm 2021 inside the n-shaped connecting seat 2012. The horizontal moving grooves 2025 are connected to the T-shaped slide groove 2023.

[0081] The first locking rod 2026 is horizontally slidably installed on the inner side of the T-shaped slide groove 2023 and passes through the horizontal moving groove 2025 and extends to the inner side of the first limiting rail groove 2014.

[0082] The fixed stop 2028 is fixed to the top of one end of the T-shaped slide groove 2023 near the n-shaped connecting seat 2012. The first spring piece 2027 is disposed between the fixed stop 2028 and the first locking rod 2026. One end of the first spring piece 2027 is fixedly connected to the first locking rod 2026, and the other end is attached to the fixed stop 2028 but not connected.

[0083] The first limiting groove 2014 is composed of a first arc groove and a first horizontal groove. When the first locking rod 2026 is located inside the first horizontal groove, it is used to lock the rotating arm 2021 in a horizontal state. When the first locking rod 2026 moves to the inside of the first arc groove, it is used to release the lock on the rotating arm 2021, so that the rotating arm 2021 can rotate.

[0084] The extension unit 203 includes a telescopic arm 2031 and a second locking rod 2032;

[0085] The telescopic arm 2031 is slidably connected to the inner side of the T-shaped slide groove 2023 and extends to the outer end of the rotating arm 2021 away from the n-shaped connecting seat 2012;

[0086] The second locking rod 2032 is symmetrically fixed on both sides of one end of the telescopic arm 2031. Horizontal sliding grooves 2024 are provided on both sides of the outer wall of the rotating arm 2021. The second locking rod 2032 is slidably connected to the inner side of the horizontal sliding groove 2024.

[0087] The n-type connector 2012 is also provided with second limiting grooves 2015 on both sides. The second limiting grooves 2015 are located outside the first locking rod 2026. The second limiting grooves 2015 are composed of a second arc groove and a second horizontal groove. The second horizontal groove passes through one end of the n-type connector 2012.

[0088] When the rotating arm 2021 is in a horizontal state, one end of the horizontal slide 2024 is flush with the second horizontal groove. The second locking rod 2032 can move into the second horizontal groove through the horizontal slide 2024. When the telescopic arm 2031 rotates synchronously with the rotating arm 2021, the second locking rod 2032 moves into the second arc groove to achieve relative locking between the telescopic arm 2031 and the rotating arm 2021.

[0089] In this embodiment, it should be noted that when the radar level gauge 4 is suspended above the water surface for water level monitoring, the first locking rod 2026 is located inside the first horizontal groove in the first limiting rail groove 2014, thus keeping the rotating arm 2021 in a stable horizontal state. When the radar level gauge 4 needs to be repaired, the drive assembly 6 can be operated with external tools. The drive assembly 6 will provide a downward tilting pulling force to the telescopic arm 2031. At this time, the operation steps of the rotating unit 202 and the extension unit 203 are as follows:

[0090] The extension unit 203 retracts: Due to the mutual cooperation and limitation between the first locking rod 2026 and the first horizontal groove, the rotating arm 2021 and the telescopic arm 2031 cannot rotate. Therefore, the telescopic arm 2031 will retract towards the rotating arm 2021 under the action of the downward inclined pulling force, so that the radar water level gauge 4 moves closer to the position of the column 102 from above the water surface.

[0091] Unlocking of rotating unit 202: As telescopic arm 2031 retracts, telescopic arm 2031 will contact and press against the first locking rod 2026. The first locking rod 2026 is pressed and moves along the horizontal moving groove 2025. Its first spring piece 2027 deforms and contracts. The first locking rod 2026 will move from the first horizontal groove to the inside of the first arc groove, thus releasing the horizontal limit on rotating arm 2021, allowing rotating arm 2021 to rotate.

[0092] The second locking rod 2032 docks with the second limiting rail groove 2015: while the telescopic arm 2031 contacts the first locking rod 2026, the second locking rod 2032 moves synchronously into the second horizontal groove along with the telescopic arm 2031, and when the first locking rod 2026 reaches the first arc groove, the second locking rod 2032 moves synchronously into the second arc groove.

[0093] Rotating unit 202 and extending unit 203 rotate downwards synchronously: When the first locking rod 2026 moves into the first arc-shaped groove, the telescopic arm 2031 completes its retraction and cannot continue to retract. At this time, the tilting force will pull the telescopic arm 2031 and the rotating arm 2021 to rotate downwards as a whole. At this time, the first locking rod 2026 moves along the trajectory of the first arc-shaped groove, and the second locking rod 2032 rotates along the second arc-shaped groove. Through this structure, during the downward rotation, the telescopic arm 2031 and the rotating arm 2021 maintain a relatively locked state, and the telescopic arm 2031 will not move outwards from the rotating arm 2021.

[0094] When the rotating unit 202 and the extending unit 203 have finished rotating downwards, the radar level gauge 4 is close to the ground and the column 102, which makes it easier to inspect and replace the radar level gauge 4.

[0095] Then, the drive component 6 is operated in reverse. Its rotation unit 202 and extension unit 203 will first rotate upward synchronously, and then the extension unit 203 will extend outward, so that the radar level gauge 4 is extended above the water surface, thus completing the stable placement of the radar level gauge 4.

[0096] Please refer to this carefully. Figures 7 to 13 The clamping assembly 3 includes a fixed clamping block 301, a rotating block 302, a rotating column 303, a torsion spring 304, a rotating clamping block 305, an arc-shaped docking block 306, a second spring piece 310, and a 7-shaped self-locking block 311.

[0097] The fixing block 301 is fixed to the end of the telescopic arm 2031 away from the rotating arm 2021, and the top of the fixing block 301 protrudes above the telescopic arm 2031.

[0098] A rotating groove is provided at the end of the fixed clamping block 301 away from the telescopic arm 2031. The rotating block 302 is rotatably installed inside the rotating groove through the rotating column 303. The torsion spring 304 is sleeved on the outside of the rotating column 303 and its two ends are respectively engaged with the outer wall of the rotating block 302 and the inner wall of the rotating groove. The rotating clamping block 305 is fixed on one side of the rotating block 302 and is symmetrically distributed with the fixed clamping block 301. The inner area formed by the fixed clamping block 301 and the rotating block 302 is used to clamp and fix the radar level gauge 4.

[0099] The fixed clamping block 301 has an arc-shaped docking groove 308 and a telescopic groove 309 inside one end near the telescopic arm 2031. The arc-shaped docking groove 308 extends through to one side of the fixed clamping block 301, and the telescopic groove 309 is perpendicular to the arc-shaped docking groove 308 and extends through to the outside of the fixed clamping block 301 near the telescopic arm 2031.

[0100] The arc-shaped docking block 306 is fixed to one side of the rotating clamping block 305 and snapped into the inner side of the arc-shaped docking groove 308 to realize the pre-connection between the fixed clamping block 301 and the rotating block 302. The top of the arc-shaped docking block 306 is provided with a self-locking groove 307.

[0101] The second spring 310 and the 7-shaped self-locking block 311 are installed inside the telescopic groove 309. The 7-shaped self-locking block 311 is connected to one end of the second spring 310 and is locked inside the self-locking groove 307 to achieve the position locking of the arc-shaped docking block 306.

[0102] Unlocking component 5 includes a horizontal through groove 501, a reset slide groove 502, a telescopic top rod 503, a pressure block 504, and a third spring piece 505;

[0103] The horizontal through groove 501 is formed inside the rotating arm 2021 and passes through both ends of the rotating arm 2021. The horizontal through groove 501 is located above the T-shaped slide groove 2023.

[0104] The reset groove 502 is located at the top of the rotating arm 2021 and is connected to the horizontal through groove 501;

[0105] The telescopic top rod 503 is slidably installed on the inner side of the horizontal through groove 501, and one end of the telescopic top rod 503 protrudes from the outer end of the rotating arm 2021 and is located in the n-type connecting seat 2012. The other end of the telescopic top rod 503 is flush with the other end face of the rotating arm 2021. The moving telescopic top rod 503 protrudes to the other end face of the rotating arm 2021 and presses the 7-shaped self-locking block 311 to realize the separation of the 7-shaped self-locking block 311 from the self-locking slot 307.

[0106] The pressure block 504 is slidably connected to the inner side of the reset slide groove 502 and is fixed perpendicularly to the horizontal through groove 501. The third spring piece 505 is disposed on the inner side of the reset slide groove 502, and one end of the third spring piece 505 is connected to the pressure block 504, while the other end is attached to the inner wall end face of the reset slide groove 502 but not connected. The third spring piece 505 is used to provide reset power for the movement of the horizontal through groove 501.

[0107] In this embodiment, it should be noted that: the inner sides of the fixed clamping block 301 and the rotating clamping block 305 are formed with polygonal grooves, which match a section of the polygonal outer wall on the radar level gauge 4. During the use of the radar level gauge 4, the arc-shaped docking block 306 is locked inside the arc-shaped docking groove 308, and the bottom vertical part of the 7-shaped self-locking block 311 is locked in the self-locking slot 307. The top horizontal part of the 7-shaped self-locking block 311 protrudes to one end of the fixed clamping block 301 and is flush with the outer end face of the fixed clamping block 301. This allows the fixed clamping block 301 and the rotating clamping block 305 to maintain a stable closed state. The clamping assembly 3 can form a stable clamp on the radar level gauge 4.

[0108] During the process of retracting and rotating the cross frame assembly 2 driven by the drive assembly 6, when the telescopic arm 2031 is fully retracted into the rotating arm 2021, the fixed clamping block 301 is close to the end face of the rotating arm 2021, and the top horizontal part of the 7-shaped self-locking block 311 is aligned with the telescopic top rod 503. However, at this time, the telescopic top rod 503 does not press the top horizontal part of the 7-shaped self-locking block 311, that is, at this time, the clamping assembly 3 maintains a stable self-locking state.

[0109] Subsequently, when the rotating arm 2021 and the telescopic arm 2031 rotate downwards, the end of the telescopic rod 503 protruding outside the rotating arm 2021 will contact the top of the inner wall of the n-type connecting seat 2012. The telescopic rod 503 will be subjected to a compressive force, which will push the telescopic rod 503 closer to the fixed clamping block 301. At the same time, the telescopic rod 503 will compress the third spring 505 through the pressure block 504 to deform and contract. The moving telescopic rod 503 will compress the transverse part of the top of the 7-shaped self-locking block 311. The 7-shaped self-locking block 311 will retract into the telescopic groove 309 and squeeze the second spring 310 to deform and retract. When the rotating arm 2021 and the telescopic arm 2031 have completed their downward rotation, the vertical part at the bottom of the 7-shaped self-locking block 311 will be completely separated from the self-locking groove 307, thus releasing the lock on the arc-shaped docking block 306. (It should be noted that the telescopic top rod 503 and the horizontal part at the top of the 7-shaped self-locking block 311 are misaligned with the arc-shaped docking block 306 and will not interfere with the movement of the arc-shaped docking block 306.)

[0110] At this point, the rotating clamp 305 can be loosened and rotated to open it, so that the radar level gauge 4 can be taken out. It should also be noted that the torque of the torsion spring 304 can keep the rotating clamp 305 and the fixed clamp 301 in a close fit. In this way, when there is no external force to rotate the rotating clamp 305, the radar level gauge 4 can be fixed between the rotating clamp 305 and the fixed clamp 301 and will not fall off.

[0111] When the rotating arm 2021 returns to the horizontal state, the telescopic top rod 503 will be reset under the action of the third spring plate 505, so that the 7-shaped self-locking block 311 is reset to the left and right of the second spring plate 310 and locked inside the self-locking slot 307, thus ensuring the clamping stability of the radar level gauge 4 during daily use.

[0112] Please refer to this carefully. Figures 1 to 5 The drive assembly 6 includes a threaded rod 601, a first bevel gear 602, a second bevel gear 603, an external end post 604, a lifting ring seat 605, a connecting block 606, a second rotating seat 607, and a linkage arm 608.

[0113] The interior of the column 102 is provided with a transmission groove 104 and a lifting groove 105 that extend to the top of the column 102. The lifting groove 105 extends to the outside of the column 102 and is flush with the telescopic arm 2031.

[0114] The threaded rod 601 is rotatably mounted inside the transmission groove 104. The first bevel gear 602 is fixed to the bottom outer wall of the threaded rod 601. The external end post 604 extends from one side of the bottom of the post 102 into the transmission groove 104. The second bevel gear 603 is fixed to one side of the external end post 604 and meshes with the first bevel gear 602.

[0115] The lifting ring seat 605 is slidably installed on the inner side of the transmission groove 104 and threadedly connected to the threaded rod 601. The connecting block 606 is fixed to one end of the lifting ring seat 605 and passes through the lifting groove 105 to the outside of the column 102. The second rotating seat 607 is fixed to one end of the connecting block 606. The two ends of the linkage arm 608 are rotatably connected to the second rotating seat 607 and the first rotating seat 2033, respectively. The lifting ring seat 605, which moves up and down, provides power for the rotation and extension of the cross frame assembly 2 through the transmission of the linkage arm 608.

[0116] In this embodiment, it should be noted that: the outer end post 604 is provided with a polygonal hole at one end outside the column 102, which is used for inserting external tools to rotate the outer end post 604. The rotation of the outer end post 604 can drive the threaded rod 601 to rotate through the transmission between the second bevel gear 603 and the first bevel gear 602. The rotation of the threaded rod 601 can cause the lifting ring seat 605, the connecting block 606, and the second rotating seat 607 to move up and down as a whole.

[0117] When the second rotating seat 607 moves downward, it can provide a downward pulling force to the telescopic arm 2031 through the transmission of the linkage arm 608 and the first rotating seat 2033, thus providing power for the retraction and downward rotation of the cross frame assembly 2.

[0118] When the second rotating seat 607 moves upward, it can provide an upward thrust to the telescopic arm 2031, thus providing power for the upward rotation and extension of the crossbeam assembly 2.

[0119] Please refer to this carefully. Figures 1 to 4 The inner wall of the lifting groove 105 is provided with T-shaped slots 106 on both sides. A sealing strip 107 is installed on the inner side of the T-shaped slot 106. The width of the connecting block 606 is smaller than the width of the inner wall of the lifting groove 105. The sealing strip 107 is used to protect the port of the lifting groove 105.

[0120] A control cabinet 108 is fixedly installed on the outside of the mounting base 101. A through hole 2016 is opened inside the arc-shaped mounting plate 2011. The control cabinet 108, the through hole 2016 and the lifting groove 105 are aligned. The data wire of the radar level gauge 4 passes through the through hole 2016 and the inside of the lifting groove 105 and extends into the control cabinet 108 to be electrically connected to the data processor inside the control cabinet 108.

[0121] In this embodiment: the sealing strip 107 can prevent external dust from entering the transmission groove 104. The structure of the connecting block 606 with a width smaller than the inner wall width of the lifting groove 105 provides space for the shrinkage of the sealing strip 107 and the installation of the data wire of the radar level gauge 4.

[0122] Please refer to this carefully. Figures 1 to 3A top cap 103 is fixedly connected to the top of the column 102. The top of the inner wall of the top cap 103 is provided with a rotating groove for the top of the threaded rod 601 to be inserted.

[0123] In this embodiment: the top cap 103 can shield and protect the top of the transmission groove 104 and the lifting groove 105, and at the same time, the top cap 103 can provide support and limit the top of the threaded rod 601 to ensure the rotational stability of the threaded rod 601.

[0124] It should also be noted that in actual use, this device will also be equipped with supporting equipment such as rain gauges and solar panels on the outside of the column 102.
