Description

Technical Field

[0001] The utility model belongs to the technical field of water level monitoring equipment, in particular to a water level monitoring equipment for a water conservancy project which is easy to adjust. Background Art

[0002] Water level monitoring equipment for water conservancy projects is a special instrument and equipment used to measure and monitor the water level height of water bodies in water conservancy projects. These devices can obtain water level data in real time and accurately, and can also help prevent natural disasters such as floods and droughts, as well as assess the status of water bodies such as rivers, lakes, and reservoirs. Water level monitoring equipment provides an important basis for the operation and management of water conservancy projects, flood control scheduling, and water resources management.

[0003] When using existing water level monitoring equipment, most of them directly fix the radar level meter on the outside of the rod body, which makes the radar level meter difficult to move. The working principle of the radar level meter is to measure the water level by emitting microwave signals and receiving reflected signals. However, since different water bodies have different water level variation ranges, adjusting the height of the radar level meter can ensure that the level meter can effectively work within the entire water level variation range. If the radar level meter is installed at an inappropriate height, measurement errors may occur, thereby affecting the accuracy of the data. Therefore, a water level monitoring device for a water conservancy project that is easy to adjust is proposed to solve the problems raised in the background technology. Utility Model Content

[0007] Preferably, a protrusion is provided at a 180-degree angle on the bottom end of the round rod, and the protrusion is movably engaged with the bottom of the guide groove in an initial state.

[0008] Preferably, the first bevel gear is meshed with the second bevel gear, the second bevel gear rotates around the rotating shaft, and the end of the threaded rod away from the second bevel gear penetrates the outer wall of the rod body and extends to the outside of the rod body.

[0009] Preferably, one end of the threaded rod is provided with a block that moves inside the rotating shaft, and the inner wall of the rotating shaft is provided with a cross groove for limiting the block. When the threaded rod rotates, the threaded rod slides inside the cross groove and drives the rotating shaft to rotate at the same time.

[0010] Preferably, when the rotating drum rotates, it drives the round rod to move upward along the track of the guide groove. When the round rod drives the supporting rod to move upward, the connecting rod drives the slider to move toward the round rod.

Then, the first bevel gear is meshed with the second bevel gear, thereby driving the rotating drum to rotate through the first bevel gear, and then the protrusion drives the round rod to move upward along the trajectory of the guide groove.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, the utility model provides a water level monitoring device for a water conservancy project that is easy to adjust, including a rod body 1, a solar cell panel 2 is provided in the middle of the outer wall of the rod body 1, a round rod 7 and a rotating drum 8 are movably connected inside the rod body 1, the top of the round rod 7 is fixedly connected to a support rod 3, and the end of the support rod 3 away from the rod body 1 is fixedly connected to a radar level gauge 4, a slider 5 is movably sleeved on the outer surface of the support rod 3, a connecting rod 6 is hinged to the bottom of the slider 5, a guide groove 9 is opened in an annular manner at 180 degrees on the inner wall of the rotating drum 8, a first bevel gear 10 is fixedly connected to the bottom of the rotating drum 8, a second bevel gear 11 is movably connected to the inside of the rod body 1, a rotating shaft 12 is fixedly connected to the middle of the second bevel gear 11, and a threaded rod 14 is threadedly connected to the outer wall of the rod body 1.

[0021] The above scheme is adopted: the threaded rod 14 is limited by the cross groove 13, so that when the threaded rod 14 rotates, the rotating shaft 12 and the second bevel gear 11 are driven to rotate, and then the first bevel gear 10 is engaged with the second bevel gear 11, so that the rotating drum 8 is driven to rotate through the first bevel gear 10, and then the protrusion drives the round rod 7 to move upward along the trajectory of the guide groove 9. When the round rod 7 moves upward, it drives the support rod 3 and the radar level meter 4 to move, thereby facilitating the adjustment of the height of the radar level meter 4, thereby improving the measurement accuracy of the water level monitoring equipment.

[0022] like Figures 1 to 4 As shown, the end of the support rod 3 away from the round rod 7 passes through the outer wall of the rod body 1 and extends to the outside of the rod body 1, the end of the connecting rod 6 away from the slider 5 is hinged to the outer wall of the rod body 1, and the bottom end of the round rod 7 is provided with a protrusion in a ring shape at 180 degrees. In the initial state, the protrusion is movably engaged with the bottom of the guide groove 9, the first bevel gear 10 is meshed with the second bevel gear 11, and the second bevel gear 11 rotates around the rotating shaft 12 as the axis, and the end of the threaded rod 14 away from the second bevel gear 11 passes through the outer wall of the rod body 1 and extends to the outside of the rod body 1.

[0023] The above solution is adopted: through the design of the connecting rod 6, its function is to form a triangular structure between the connecting rod 6 and the support rod 3, and the triangle has stability in the geometric structure. This stable structure can provide more reliable support for the support rod 3, thereby enhancing the overall stability of the device.

[0024] like Figures 2 to 4 As shown, the threaded rod 14 is provided with a block movable inside the rotating shaft 12 at one end close to the second bevel gear 11, and a cross groove 13 is provided on the inner wall of the rotating shaft 12 for limiting the block. When the rotating drum 8 rotates, it drives the round rod 7 to move upward along the trajectory of the guide groove 9. When the round rod 7 drives the support rod 3 to move upward, the connecting rod 6 drives the slider 5 to move toward the direction of the round rod 7. A limiting block is provided in the middle of the outer wall of the round rod 7, and a straight slot 15 is provided on the inner wall of the rod body 1 to cooperate with the limiting block. The straight slot 15 is used to circumferentially limit the round rod 7 when the rotating drum 8 rotates.

[0025] The above solution is adopted: through the design of the cross groove 13, its function is that when the threaded rod 14 rotates, the cross groove 13 limits the block of the threaded rod 14, so that the threaded rod 14 slides inside the cross groove 13 and drives the rotating shaft 12 to rotate.

[0026] When the support rod 3 moves upward, the slider 5 slides outside the support rod 3. Figure 2 It can be seen that a triangular geometric relationship is formed between the rod body 1, the support rod 3 and the connecting rod 6. After the support rod 3 moves upward, the angle of the triangle will change. At this time, the slider 5 slides on the outside of the support rod 3 to adapt to the length change between the support rod 3 and the connecting rod 6, thereby ensuring the stable operation of the device.

[0027] The working principle and use process of the utility model are as follows: when the liquid level range to be measured changes, the operator rotates the threaded rod 14 and limits the threaded rod 14 block through the cross groove 13, so that the rotating shaft 12 rotates along with the threaded rod 14. When the rotating shaft 12 rotates, it drives the second bevel gear 11 on its outer wall to rotate, and the second bevel gear 11 is engaged with the first bevel gear 10, thereby driving the rotating drum 8 to rotate through the first bevel gear 10. When the rotating drum 8 rotates, it drives the protrusion at the bottom end of the round rod 7 to move along the track of the guide groove 9. The threaded rod 14 stops rotating, and the position of the support rod 3 and the radar level gauge 4 is fixed, so that the height of the radar level gauge 4 can be easily adjusted. At the same time, the support rod 3 is supported by the connecting rod 6, so as to ensure the stability of the support rod 3 and the radar level gauge 4 when moving.
