Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower, and in particular to a water level benchmark for water conservancy and hydropower. Background Technology

[0002] An existing patent (publication number: CN220729381U) discloses a water level indicator for hydropower projects, comprising a base, a support column fixedly mounted on the top of the base, a groove on the front surface of the support column, a scale plate movably mounted inside the groove, four mounting slots inside the scale plate, a return spring fixedly mounted on the inner wall of the mounting slot, a limit block fixedly mounted on the right side of the return spring, four ejection slots inside the support column, four movable holes on the inner wall of the groove, two compression springs fixedly mounted on the inner wall of the ejection slot, an ejection mechanism fixedly mounted between the right sides of the two compression springs, and a T-shaped groove on the front surface of the scale plate. However, in this device, workers observe the water level on the scale plate through an airbag, resulting in poor warning effectiveness. It cannot provide warnings when the water level is too high, hindering monitoring personnel from promptly detecting potential hazards, thus presenting drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a water level benchmark that is easy to assemble and disassemble, provides stable support, facilitates rapid and accurate reading of water level height, and can provide dynamic warnings when the water level is too high, prompting monitoring personnel to promptly detect potential dangers and implement water safety protection measures.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A water level marker for water conservancy and hydropower includes a cement base, a support block, a rotating block, a fastening plate, an indicator frame, a hollow float, a marker sleeve, and a warning disc. The marker sleeve has scale lines on both sides, and the indicator frame is connected to the outside of the marker sleeve. The indicator frame has reading ports on both sides. The support block is connected to the inside of the marker sleeve, and the support block has a recessed groove. The marker sleeve has a limiting strip that is adapted to the recessed groove and connected to it. The support block has fastening threaded grooves on both sides, the marker sleeve has sliding holes on both sides, and the indicator frame has connecting rod through holes on both sides. The connecting rod through holes, sliding holes, and fastening threaded grooves are adapted to the connecting rod. The connecting rod passes through the connecting rod through holes and sliding holes in sequence, and the inner end of the connecting rod is threaded into the fastening threaded groove. The outer end of the connecting rod is connected to the hollow float.

[0006] The present invention describes a support block with a rotating block connected to the upper part to form a placement groove. The placement groove is adapted to the fastening plate and is connected to the fastening plate. The upper side of the fastening plate has an upper retaining plate, and the rotating block has an upper retaining groove. The upper retaining plate is adapted to the upper retaining groove and is connected to the upper retaining groove. The lower side of the fastening plate has a lower retaining plate, and the support block has a lower retaining groove. The lower retaining plate is adapted to the lower retaining groove and is connected to the lower retaining groove. The rotating block is externally connected to a marker sleeve. The rotating block has an upper groove, and the upper groove is adapted to the limiting strip plate and is connected to the upper groove.

[0007] The rotating block of this utility model has a rotating rod at the bottom, which is connected to the inside of the bearing. The bearing is connected to a support block at the outside. The rotating block has a support rod at the top. The upper part of the marker sleeve has an upper through hole. The support rod is adapted to the upper through hole and passes through the upper through hole. The upper end of the support rod is connected to a warning disc. The warning disc has multiple warning rods.

[0008] The lower part of the marker sleeve of this utility model is connected to a fixed base plate. The upper part of the fixed base plate has a fixed support sleeve and a reinforcing support rod. The fixed support sleeve is connected to the outside of the marker sleeve, and the inner side of the marker sleeve is connected to the reinforcing support rod. The fixed bolts are connected to the fixed support sleeve, the marker sleeve, and the reinforcing support rod in sequence. The upper part of the cement base has an installation support sleeve, which is connected to the fixed base plate. The lower part of the fixed base plate has an installation support rod, which is connected to the installation support sleeve by a thread. Beneficial effects

[0009] This utility model adds a connecting fulcrum between the indicator frame, the marker sleeve, and the support block, and uses a hollow float to drive the indicator frame and the support block to automatically float and rise with the water level, so that the support block, the indicator frame and the water surface always maintain a uniform height. This makes it easy for workers to quickly read the water level through the reading port and scale lines, and is convenient to use.

[0010] The limiting plate inside the marker sleeve of this utility model limits the position of the supporting block and the rotating block, keeping them in longitudinal linear displacement and preventing them from rotating. This causes the warning rod to maintain axial static lifting and lowering at a reasonable water level. The highest point of the limiting plate is the water level warning height. When the hollow float moves the supporting block to the highest point of the limiting plate, the upper groove of the rotating block is disengaged from the limiting plate. At this time, the positioning fulcrum of the rotating block disappears, and under the action of wind, the static warning rod rotates with the wind, forming a dynamic warning, so as to prompt monitoring personnel to detect dangers in time and take water conservancy safety protection measures.

[0011] The fastening plate of this utility model has an upper clamping plate and a lower clamping plate that are embedded and plugged into the rotating block and the supporting block, respectively, increasing the connection fulcrum between the two. This ensures that the two always maintain synchronous lifting and lowering, while limiting the position of the rotating block. This allows it to rotate axially while maintaining a constant longitudinal relative height with the supporting block, preventing it from separating from the supporting block and causing misjudgment of the water level height, thus improving structural stability.

[0012] This utility model features a cement base that is fixed to the bottom of the river, providing a positioning fulcrum for the installation of the marker sleeve. The mounting rod and mounting sleeve are screwed together, facilitating easy assembly and disassembly and improving the efficiency of water level marker installation and disassembly operations in water conservancy and hydropower projects. The reinforcing rod and fixing sleeve on the upper part of the fixed base plate clamp and support the inner and outer sides of the marker sleeve, increasing the support strength at the bottom of the marker sleeve and ensuring it remains vertical, preventing tilting and thus avoiding errors in water level readings.

The support block 10 is connected to the inside of the marker sleeve 29, and the support block 10 has a lower groove 09. The marker sleeve 29 has a limiting strip 07 that is adapted to the lower groove 09 and connected to the lower groove 09. The support block 10 has fastening threaded grooves 26 on both sides, the marker sleeve 29 has sliding holes 27 on both sides, and the indicator frame 23 has... The connecting rod through hole 28, the sliding hole 27, and the fastening threaded groove 26 are adapted to the connecting rod 25. The connecting rod 25 passes through the connecting rod through hole 28 and the sliding hole 27 in sequence. The inner end of the connecting rod 25 is connected to the fastening threaded groove 26 by a thread. The outer end of the connecting rod 25 is connected to the hollow float 24. The connecting rod 25 adds a fulcrum between the indicator frame 23, the marker sleeve 29, and the support block 10. At the same time, the hollow float 24 drives the indicator frame 23 and the support block 10 to float and rise automatically with the water level. This ensures that the support block 10, the indicator frame 23 and the water surface are always at the same height, which makes it easy for the operator to quickly read the water level through the reading port 21 and the scale line 20. It is convenient to use.

[0027] Example 2:

[0028] The supporting block 10 of this utility model has a rotating block 11 connected to its upper part to form a placement groove 15. The placement groove 15 is adapted to the fastening plate 14 and is connected to the fastening plate 14. The fastening plate 14 has an upper retaining plate 16 on its upper side, and the rotating block 11 has an upper retaining groove 17. The upper retaining plate 16 is adapted to the upper retaining groove 17 and is connected to the upper retaining groove 17.

The lower retaining plate 18 is adapted to the lower retaining groove 19 and is connected to the lower retaining groove 19. The rotating block 11 is externally connected to a marker sleeve 29. The rotating block 11 has an upper groove 08, which is adapted to the limiting strip 07. The limiting strip 07 is connected to the upper groove 08. The fastening plate 14 has an upper clamping plate 16 and a lower clamping plate 18 that are respectively embedded and inserted between the rotating block 11 and the supporting block 10, increasing the connection fulcrum between the two, so that the two always maintain synchronous lifting and lowering, while limiting the position of the rotating block 11, so that it can rotate axially while maintaining a constant longitudinal relative height with the supporting block 10, preventing it from separating from the supporting block 10 and causing misjudgment of the water level height, thus improving the structural stability.

[0029] Example 3:

[0030] The rotating block 11 of this invention has a rotating rod 13 at its lower part, which is connected to the inside of the bearing 12. The bearing 12 is connected to the outside of the support block 10. The rotating block 11 has a support rod 30 at its upper part. The upper part of the marker sleeve 29 has an upper through hole 31. The support rod 30 is adapted to the upper through hole 31 and passes through the upper through hole 31. The upper end of the support rod 30 is connected to a warning disc 32. The warning disc 32 has multiple warning rods 33. The limiting strip 07 provided inside the marker sleeve 29 limits the position of the support block 10 and the rotating block 11, so that they maintain longitudinal linear displacement. To prevent the two from rotating, the warning rod 33 maintains a static axial rise and fall at a reasonable water level. The highest point of the limiting plate 07 is the water level warning height. When the hollow float 24 drives the supporting block 10 to move up to the highest point of the limiting plate 07, the upper groove 08 of the rotating block 11 is disengaged from the limiting plate 07. At this time, the positioning fulcrum of the rotating block 11 disappears, and under the action of wind, the static warning rod 33 rotates with the wind to form a dynamic warning, so as to prompt the monitoring personnel to discover the danger in time and take water conservancy safety protection measures.

[0031] Example 4:
