Description

Technical Field

[0001] This utility model relates to the field of water level monitoring equipment technology, and in particular to a river water level monitoring device. Background Technology

[0002] River water level monitoring refers to the use of monitoring instruments to monitor river water levels in real time in order to obtain water level information, thereby providing data support for flood warning, water resource management, ecological environment protection and urban planning.

[0003] While existing patents CN217899374U and CN218954469U disclose a river water level monitoring device, which adds horizontal and vertical movement capabilities to the water level monitor for easy retrieval and maintenance, the direction of the lateral support arm supporting the monitor remains unchanged. This means that in scenarios such as working on slopes or embankments near the river, where the support arm extends towards the water, when the monitor moves to a support column close to the bank, a person still needs to stand on the water-adjacent side to remove it for maintenance. This requires workers to stand on slopes or embankments, risking falling into the water. Therefore, it is necessary to add a rotation function to the river water level monitoring device to reduce safety hazards during maintenance. Utility Model Content

[0032] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 4 As shown, this embodiment discloses a river water level monitoring device, including a fixed rod 11 with a cavity, a rotatable screw 1 disposed within the cavity of the fixed rod 11, the bottom of the screw 1 being connected to a drive assembly 2, and both the fixed rod 11 and the drive assembly 2 being mounted on a base 3. A threaded lifting rod 4 is sleeved on the outside of the screw 1, the top end of the lifting rod 4 being rotatably connected to one end of a support arm 7, and an ultrasonic water level gauge 8 being disposed at the other end of the support arm 7. An operating rod 9 is disposed on the end of the support arm 7 rotatably connected to the lifting rod 4, and the operating rod 9 is slidably connected to an operating panel 6. The lifting rod 4 is slidably disposed within the cavity of the fixed rod 11, the outer wall of the lifting rod 4 being square, and the inner wall of the fixed rod 11 being square to match the outer wall of the lifting rod 4.

[0034] The screw 1 is driven to rotate by the drive assembly 2, thereby causing the lifting rod 4 to rise and fall under the guidance of its square outer wall and the inner wall of the fixed rod 11. It should be noted that, to enhance the guiding effect, a guide rail can be provided on the outer wall of the lifting rod 4, and a matching sliding groove can be provided on the inner wall of the fixed rod 11. The two are slidably connected, and a sealing ring is provided at the opening where the fixed rod 11 contacts the lifting rod 4 to prevent rainwater from falling into the fixed rod 11. The operating lever 9 can rotate circumferentially on the operating panel 6. Pushing the operating lever 9 causes the support arm 7 to rotate. After rotation, the operating lever 9 and the operating panel 6 are connected together by the locking assembly 10. The ultrasonic water level gauge 8 is existing technology and will not be described here.

[0035] like Figures 3 to 5 As shown, screw 1 is rotatably connected to base 3, and a first gear 1-1 is fixedly mounted on the bottom of screw 1. The drive assembly 2 includes a motor 2-1 mounted on base 3. A third gear 2-2 is fixedly mounted on the output end of motor 2-1. The third gear 2-2 meshes with a second gear 2-3, which in turn meshes with the first gear 1-1. The second gear 2-3 is mounted on base 3. When motor 2-1 is started, the third gear 2-2 begins to rotate, which, with the help of the second gear 2-3 and the first gear 1-1, drives screw 1 to rotate. It should be noted that in this embodiment, the length of the lifting rod 4, when lowered to its lowest position, will not press against the first gear 1-1.

[0036] In one embodiment of realizing the rotational connection between the top end of the lifting rod 4 and one end of the support arm 7, a frustum 4-1 is fixedly provided at the top end of the lifting rod 4. The frustum 4-1 is connected to the inner ring of the bearing 5, and the outer ring of the bearing 5 is connected to one end of the support arm 7, thereby realizing the rotational connection between the support arm 7 and the top end of the lifting rod 4.

[0037] like Figure 6 As shown, the operating panel 6 includes a panel body 6-1, on which an arc-shaped groove 6-3 is provided. A sliding disc 6-4 is slidably connected within the arc-shaped groove 6-3. A second sliding hole 6-5 is provided on the sliding disc 6-4, and an operating lever 9 is slidably disposed within the second sliding hole 6-5. The top end of the operating lever 9 is fixedly connected to one end of the support arm 7, which is rotatably connected to the lifting rod 4. When it is necessary to adjust the rotation angle of the support arm 7, the operating lever 9 is pushed along the circumference of the operating panel 6. The operating lever 9, along with the sliding disc 6-4, rotates within the arc-shaped groove 6-3, thereby adjusting the support arm 7 to a suitable angle. Moreover, the operating lever 9 can slide up and down within the sliding disc 6-4, thus not affecting the lifting operation of the lifting rod 4.

[0038] In this embodiment, a second limiting block 9-1 is provided at the bottom of the operating rod 9. The second limiting block 9-1 is located below the second sliding hole 6-5. The second limiting block 9-1 is in a limiting fit with the second sliding hole 6-5 to prevent the operating rod 9 from coming out of the second sliding hole 6-5.

[0039] like Figures 6 to 7 As shown, the disc body 6-1 is provided with a first annular platform 6-6 and a second annular platform 6-2. The second annular platform 6-2 is located on the outer edge of the disc body 6-1, and the arc-shaped groove 6-3 is located between the first annular platform 6-6 and the second annular platform 6-2. It should be noted that since the support arm 7 only needs to be rotated from the water surface to the shore for maintenance, it is not necessary to achieve a 180-degree rotation effect. In this embodiment, the arc-shaped groove 6-3 is a 130-degree arc groove, which is sufficient to meet the working requirements.

[0040] The first annular platform 6-6 has multiple horizontally arranged first locking holes 6-6-1 on its circumferential surface, and the second annular platform 6-2 has multiple vertically arranged second locking holes 6-2-1.

[0041] like Figure 8As shown, the locking assembly 10 includes a U-shaped rod 10-1, with insertion ends 10-2 at both ends. The insertion ends 10-2 are inserted into the first locking hole 6-6-1. A vertical locking part 10-3 is provided in the middle of the U-shaped rod 10-1, and a third locking hole 10-4 is provided on the vertical locking part 10-3. The third locking hole 10-4 is fixedly connected to the second locking hole 6-2-1 by a bolt assembly. When the support arm 7 needs to be fixed in position after rotation, the U-shaped rod 10-1 is tightly clamped onto both sides of the operating rod 9, the insertion ends 10-2 are inserted into the first locking hole 6-6-1, and the third locking hole 10-4 on the vertical locking part 10-3 is fastened to the second locking hole 6-2-1 on the second annular platform 6-2 by a bolt assembly, thus preventing the support arm 7 from rotating. Since the screw 1 and the lifting rod 4 are connected by a threaded structure, they have a self-locking function, so there is no need to lock the lifting rod 4 in the height direction.

[0042] In this embodiment, two opposing pads 10-5 are provided on the body of the U-shaped rod 10-1, and the pads 10-5 are tightly fitted against the body of the operating rod 9. A pressing part 10-6 is provided on one side of the U-shaped rod 10-1, and one of the pads 10-5 is located on the pressing part 10-6. The pressing part 10-6 is connected to the other side of the U-shaped rod 10-1 through a fastening bolt assembly 10-7. The pressing part 10-6 is a stainless steel plate structure with a certain degree of toughness. When the operating rod 9 is locked, the pads 10-5 are stuck on both sides of the operating rod 9. The fastening bolt assembly 10-7 locks the pressing part 10-6 and the other side of the U-shaped rod 10-1. During the locking process, the pressing part 10-6 gradually presses towards the operating rod 9, so that the pads 10-5 tightly clamp the operating rod 9, ensuring that the position of the support arm 7 is fixed and cannot be rotated.

[0043] like Figures 1 to 8 As shown, the operation process of this utility model is as follows:

[0044] After installing the ultrasonic level gauge 8, start the motor 2-1. The third gear 2-2 rotates, which, with the help of the second gear 2-3 and the first gear 1-1, drives the screw 1 to rotate, thereby raising the lifting rod 4 to the required height. Remove the locking assembly 10, push the operating lever 9 to rotate. The operating lever 9, along with the sliding disc 6-4, rotates within the arc-shaped groove 6-3, thereby adjusting the support arm 7 to a suitable angle. After adjustment, the pad 10-5 of the U-shaped rod 10-1 is clamped on both sides of the operating rod 9. The insertion end 10-2 is inserted into the first locking hole 6-6-1. The third locking hole 10-4 and the second locking hole 6-2-1 are fastened together by the bolt assembly. The clamping part 10-6 and the other side of the U-shaped rod 10-1 are locked together by the fastening bolt assembly 10-7. During the locking process, the clamping part 10-6 gradually presses towards the operating rod 9, so that the pad 10-5 tightly clamps the operating rod 9, ensuring that the position of the support arm 7 is fixed and can no longer rotate.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
