[0002] Water conservancy and hydropower is the field of utilizing water resources for energy development and water resources management. It involves engineering and technology that utilizes hydropower and water resources for power generation, water supply, irrigation, river management, flood control, and water resources regulation.

[0003] The water level benchmark is a reference mark for measuring water level or calibrating water level. For example, the publication number CN219328502U discloses a water conservancy and hydropower water level benchmark, including a benchmark body, a mounting base fixedly connected to the bottom end of the benchmark body, a mounting top seat fixedly connected to the top end of the benchmark body, a buzzer alarm fixedly installed in the middle of the top end of the mounting top seat, a working groove is opened in the middle of the benchmark body, and a sliding column is fixedly installed in the middle of the bottom end of the working groove. The utility model provides a water conservancy and hydropower water level benchmark. When in use, the user places the mounting base in water, and the hollow float and the hollow float rod rise and fall with the rise and fall of the water level. When the hollow float and the hollow float rod rise to the top of the benchmark body, the limit column touches the warning switch, and the warning switch controls the buzzer alarm to sound an alarm, so as to prompt the water level observer, which is safer to use. The indicator arrow on the hollow float rod is aligned with the scale line on the benchmark body, which is convenient for the water level observer to observe the water level line, and it is more convenient to use.

[0004] During the use of the above-mentioned device, due to the small diameter of the water conservancy and hydropower benchmark, the stability is not good during the vertical fixation process. Usually, a base is set at the bottom of the water conservancy and hydropower benchmark to increase the contact area between the water conservancy and hydropower benchmark and the ground to ensure its stability. In the process of moving the water conservancy and hydropower benchmark, the diameter of the base is much larger than the space of the benchmark, which affects the placement and carrying of the benchmark.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a portable water conservancy and hydropower benchmark, including a sleeve rod A1, a sleeve rod B2 and a sleeve rod C3 are all benchmark bodies, and the sleeve rod B2 and the sleeve rod C3 can be put into the sleeve rod A1 to save space and be convenient to carry. The top outer wall of the sleeve rod A1 is provided with two groups of limiting grooves B9, through which the sleeve rod B2 can be fixed when it is pulled open, and the inner wall of the sleeve rod A1 is slidably connected with the sleeve rod B2. When not in use, the sleeve rod B2 can be put into the sleeve rod A1 to save placement space and reduce volume, which is convenient to carry. The inner wall of the bottom end of the sleeve rod B2 is elastically connected with a wedge block B8 through a spring B7. When the sleeve rod B2 is pulled outward to the position of the wedge block B8 corresponding to the limiting groove B9, the wedge block B8 pops outward due to the elastic force of the spring B7 itself, and is engaged with the limiting groove B9 to fix the position of the sleeve rod B2.

[0032] Reference Figure 1-Figure 3 One end of the spring B7 is fixedly connected to the outer wall of the wedge block B8, and the other end of the spring B7 is fixedly connected to the inner wall of the sleeve rod B2. The outer wall of the wedge block B8 is slidably connected to the inner wall of the sleeve rod B2. When the sleeve rod B2 needs to be retracted, the two groups of wedge blocks B8 can be pressed inward to disengage the wedge blocks B8 from the limiting groove B9, thereby releasing the limiting of the sleeve rod B2, and the sleeve rod B2 can be retracted into the interior of the sleeve rod A1. The wedge block B8 is engaged with the limiting groove B9, and the straight surface of the wedge block B8 is in contact with the inner wall of the limiting groove B9, so that the position of the sleeve rod B2 is fixed to prevent the sleeve rod B2 from moving downward.

[0033] Reference Figure 1-Figure 3 Two groups of limiting grooves A6 are provided on the outer wall of the top end of the sleeve rod B2, and the limiting grooves A6 can be fixed when the sleeve rod C3 is pulled open. The inner wall of the sleeve rod B2 is slidably connected with the sleeve rod C3, and the sleeve rod C3 can be retracted into the interior of the sleeve rod B2 when not in use, thereby saving space. The inner wall of the bottom end of the sleeve rod C3 is elastically connected with a wedge block A5 through a spring A4. When the sleeve rod C3 is pulled upward until the position of the wedge block A5 corresponds to the limiting groove A6, the wedge block A5 pops outward due to the elastic force of the spring A4 itself, and is engaged with the limiting groove A6, so that the position of the sleeve rod C3 is fixed.

[0034] Reference Figure 1-Figure 3One end of the spring A4 is fixedly connected to the inner wall of the sleeve rod C3, and the other end of the spring A4 is fixedly connected to the outer wall of the wedge block A5. When the sleeve rod C3 needs to be retracted, the two groups of wedge blocks A5 can be pressed inward to disengage the wedge blocks A5 from the limiting groove A6, thereby releasing the limiting of the sleeve rod C3, allowing the sleeve rod C3 to move downward and retract into the interior of the sleeve rod B2. The outer wall of the wedge block A5 is slidably connected to the inner wall of the sleeve rod C3, and the wedge block A5 is engaged with the limiting groove A6. The straight surface of the wedge block A5 contacts the inner wall of the limiting groove A6, limiting the sleeve rod C3, thereby fixing the position of the sleeve rod C3.

[0035] Reference Figure 4 The outer wall of the bottom end of the sleeve rod A1 is provided with two groups of limiting grooves C10, which are engaged with the wedge blocks C16 through the limiting grooves C10, so that the sleeve rod A1 can be fixed on the base 11 conveniently and quickly. The outer wall of the bottom end of the sleeve rod A1 is provided with a quick release mechanism, which includes a base 11. The inner wall of the base 11 is plugged with the bottom of the sleeve rod A1. The base 11 can be fixed to the ground by bolts, etc. When water level measurement is required, the sleeve rod A1 can be installed on the base 11, and the sleeve rod B2 and the sleeve rod C3 can be pulled apart for use. A slide groove 12 is provided on the inner wall of the base 11. The inner wall of the slide groove 12 is rotatably connected with two groups of rotating wheels 13. When the traction rope 14 is pulled, the rotating wheel 13 can change the force direction of the traction rope 14, so that the traction rope 14 drives the two groups of wedge blocks C16 to move outward at the same time. The inner wall of the slide groove 12 is slidably connected with the traction rope 14, and the traction rope 14 is wound around the outer wall of the rotating wheel 13.

[0036] Reference Figure 4 One end of the traction rope 14 is fixedly connected to the outer wall of the partition 17, and the other end of the traction rope 14 is fixedly connected to the outer wall of the wedge block C16. The operator can pull the partition 17 to drive the traction rope 14 to move, and drive the wedge block C16 to move at the same time, thereby releasing the limit of the sleeve rod A1 and taking the sleeve rod A1 out of the base 11. The inner wall of the slide groove 12 is elastically connected with the wedge block C16 through the spring D15. One end of the spring D15 is fixedly connected to the outer wall of the wedge block C16, and the other end of the spring D15 is fixedly connected to the inner wall of the slide groove 12. When the sleeve rod A1 is installed, the sleeve rod A1 can be moved downward along the inner wall of the base 11, so that the outer wall of the bottom end of the sleeve rod A1 contacts the arc surface of the wedge block C16, and the wedge block C16 moves inward under force.

[0037] Reference Figure 4The outer wall of the wedge block C16 is slidably connected to the inner wall of the slide groove 12, and the wedge block C16 is engaged with the limit groove C10. When the sleeve rod A1 moves to the position corresponding to the wedge block C16 and the limit groove C10, the wedge block C16 pops outward due to the elastic force of the spring D15 itself and contacts with the limit groove C10, fixing the sleeve rod A1. The outer wall of the base 11 is fixedly connected to the handle 18, and the outer wall of the handle 18 is slidably connected to the partition 17. The operator can hold the handle 18 and pull the partition 17 by gripping force to conveniently and quickly release the limit of the sleeve rod A1.

[0038] Working principle: When it is necessary to use the water conservancy and hydropower benchmark to measure the water level, the sleeve rod A1 can be inserted downward along the inner wall of the base 11, so that the outer wall of the bottom end of the sleeve rod A1 contacts the arc surface of the wedge block C16, and the wedge block C16 is forced to move inward. When the sleeve rod A1 moves to the position where the wedge block C16 corresponds to the limit groove C10, the spring D15 drives the wedge block C16 to pop outward due to its own elastic force, and engages with the limit groove C10 to fix the position of the sleeve rod A1. Then the operator can pull the sleeve upward to Rod B2, when the sleeve rod B2 moves to the position corresponding to the wedge block B8 and the limit groove B9, the spring B7 drives the wedge block B8 to pop out due to its own elastic force and engages with the limit groove B9 to fix the position of the sleeve rod B2, and then the sleeve rod C3 can be pulled upward, and when the sleeve rod C3 moves to the position corresponding to the wedge block A5 and the limit groove A6, the spring A4 drives the wedge block A5 to pop out due to its own elastic force and engages with the limit groove A6 to fix the position of the sleeve rod C3, and the installation of the sleeve rod A1 is completed.

[0039] When it is not needed, the two groups of wedge blocks A5 can be pressed inward to release the limit on the sleeve rod C3, and the sleeve rod C3 can be moved downward to the inside of the sleeve rod B2. Then, the two groups of wedge blocks B8 can be pressed inward to disengage the wedge blocks B8 from the limit groove B9, and the limit of the sleeve rod B2 can be released. The sleeve rod B2 can be retracted into the interior of the sleeve rod A1. Then, the handle 18 can be held and the partition 17 can be pulled by the gripping force to make the partition 17 drive the traction rope 14 to move, and the direction of the force on the traction rope 14 can be changed by the rotating wheel 13, so that the traction rope 14 drives the wedge block C16 to move outward and disengage from the inner wall of the limit groove C10, and the limit of the sleeve rod A1 can be released. Then, the sleeve rod A1 can be removed from the inner wall of the base 11. Since the sleeve rod B2 and the sleeve rod C3 are retracted into the interior of the sleeve rod A1, space can be saved, making it more convenient for the operator to carry the sleeve rod A1.
