[0001] This utility model belongs to the field of water level measurement technology, specifically relating to a reservoir water level early warning device. Background Technology

[0002] Reservoir staff need to measure the reservoir's water level during their daily work. The obtained water level information is used for alerts and warnings. Water level measurement boats are used to measure the water level. These boats need to be manually launched into the water by staff. During launch, staff need to be close to the water's edge and even step into the water to ensure the boat is deep enough to float. Retrieving the boat also requires being close to the water's edge and even stepping into the water. However, the water's edge is slippery, and staff risk slipping and falling into the water during these processes, especially in reservoirs that utilize natural topography where the water's edge is muddy. The muddy surface becomes even more dangerous when wet. Utility Model Content

[0018] Please see Figures 1-4The present invention provides the following technical solution: a reservoir water level early warning device, comprising a small water level early warning measuring boat 1 and a water level measuring instrument 11. A drive motor 2 is installed at the bottom of the small water level early warning measuring boat 1. An adjusting screw 21 is fixedly connected to the bottom of the drive motor 2. A screw sleeve 22 is rotatably connected to the outer wall of the adjusting screw 21. A magnetic positioning plate 23 is fixedly connected to the bottom of the screw sleeve 22. A magnetic isolation cover 3 is provided on the outside of the magnetic positioning plate 23. A support rail 4 is provided on one side of the small water level early warning measuring boat 1. A boat support plate 5 is slidably connected to the top of the support rail 4. The boat support plate 5 is magnetically connected to the magnetic positioning plate 23.

[0019] In this implementation plan: the support rail 4 is installed at an angle on the reservoir bank, and the angle between the telescopic adjustment rod 44 and the turntable adjustment sleeve 43 is adjusted until the lifting angle of the small boat support plate 5 is higher than the horizontal angle. When the water level warning and measurement small boat 1 is deployed, the small boat support plate 5 is in a high position above the water surface. The staff places the water level warning and measurement small boat 1 on the top of the small boat support plate 5, and then gradually pulls the rope 42 downward. The small boat support plate 5 slides downward under the action of gravity until the water level warning and measurement small boat 1 is in the water level. After the small boat support plate 5 continues to move down a certain distance, the staff controls the water level warning and measurement small boat 1 to measure the water level of the reservoir through the remote control device. The staff can deploy the water level warning and measurement small boat 1 from a position far away from the water surface. After the water level measurement is completed, the staff moves the water level warning and measurement small boat 1 to a position close to the support rail 4 that is exposed above the water surface. Then the drive motor 2 drives the adjusting screw 21 to rotate, causing the screw sleeve 22 and the magnetic positioning plate 23 to extend downward until the bottom of the magnetic positioning plate 23. The bottom of the water level warning and measurement boat 1 is exposed. Then, the traction rope 42 is pulled to move the connecting sleeve 41 and the boat support plate 5 upward. The boat support plate 5 drags the water level warning and measurement boat 1 upward. The staff can then remove the water level warning and measurement boat 1 from the boat support plate 5. The magnetic positioning plate 23 is magnetically connected to the boat support plate 5, which can position the water level warning and measurement boat 1 and overcome the water waves generated by the movement of the boat support plate 5. This prevents the water level warning and measurement boat 1 from moving away from the corresponding position of the boat support plate 5. The staff can pick up the water level warning and measurement boat 1 from a position away from the water surface, which improves the safety of the staff using the water level warning and measurement boat 1 to measure and warn of reservoir water levels. The water level warning and measurement boat 1 does not need to be moved to the edge of the water surface, avoiding collision and damage with rocks at the edge of the water surface. During the production process, the width of the boat support plate 5 is greater than the width of the water level warning and measurement boat 1 to allow for a larger error margin and reduce the difficulty of operation for the staff.

[0020] The magnetic positioning plate 23 has a clearance groove 231 at its top, which corresponds to the size of the adjusting screw 21. By setting the clearance groove 231, the screw sleeve 22 can be made to make way, so that the magnetic positioning plate 23 can retract into the internal space of the mounting housing 31 when it is adjusted upward.

[0021] A limiting plate 24 is fixedly connected to the outer wall of the lead screw sleeve 22, and a flexible sealing sheet 25 is fixedly connected to the top of the lead screw sleeve 22. The limiting plate 24 is a rectangular plate, and the short side of the limiting plate 24 abuts against the mounting housing 31, which can limit the lead screw sleeve 22 and prevent the lead screw sleeve 22 from rotating with the adjusting lead screw 21. By setting the flexible sealing sheet 25, water can be intercepted to prevent water from contacting the drive motor 2 and causing damage to the drive motor 2.

[0022] The inner wall of the magnetic isolation cover 3 is fixedly connected to the mounting housing 31, the limiting plate 24 is slidably connected to the inner wall of the mounting housing 31, and the flexible sealing sheet 25 is fixedly connected to the mounting housing 31; the magnetic positioning plate 23 is installed at a position away from the precision parts of the water level early warning and measurement boat 1. The magnetic isolation cover 3 can further protect the internal parts of the water level early warning and measurement boat 1 and avoid damage from the magnetic force of the magnetic positioning plate 23. The mounting housing 31 facilitates the installation of the drive motor 2.

[0023] A connecting sleeve 41 is slidably connected to the top of the support rail 4. The connecting sleeve 41 is hinged to the boat support plate 5. A traction rope 42 is fixedly connected to one side of the connecting sleeve 41. The connecting sleeve 41 facilitates the connection between the boat support plate 5 and the support rail 4, and the traction rope 42 facilitates the adjustment of the positions of the connecting sleeve 41 and the boat support plate 5.

[0024] A turntable adjustment sleeve 43 is slidably connected to the top of the support rail 4. A telescopic adjustment rod 44 is hinged to the top of the turntable adjustment sleeve 43. The telescopic adjustment rod 44 is rotatably connected to the boat support plate 5. The turntable adjustment sleeve 43 consists of a sleeve and a slotted rotating disk. The rotating disk is hinged to the telescopic adjustment rod 44. After the angle of the telescopic adjustment rod 44 is adjusted, the telescopic adjustment rod 44 is fixed to the rotating disk of the turntable adjustment sleeve 43 with fastening bolts. The telescopic adjustment rod 44 consists of an outer sleeve and an inner rod. The overall length of the telescopic adjustment rod 44 is adjusted by pulling the inner rod of the telescopic adjustment rod 44 and then fixed with bolts.

[0025] The top of the boat support plate 5 is provided with a clearance notch 51 to allow for clearance; by setting the clearance notch 51, the propeller of the water level early warning measurement boat 1 can be clearanced so that the water level early warning measurement boat 1 can fit in close to the boat support plate 5.

[0026] The working principle and usage process of this utility model are as follows: The support rail 4 is installed at an angle on the bank of the reservoir. When the water level warning and measurement boat 1 is deployed, the staff places the water level warning and measurement boat 1 on top of the boat support plate 5, and then gradually pulls the rope 42 downward. The boat support plate 5 slides downward under the action of gravity until the water level warning and measurement boat 1 is in the water. After the boat support plate 5 continues to move downward a certain distance, the staff controls the water level warning and measurement boat 1 to measure the water level of the reservoir through a remote control device. After the water level measurement is completed, the staff moves the water level warning and measurement boat 1 to a position close to the support rail 4 that is exposed above the water surface. Then, the drive motor 2 drives the adjusting screw 21 to rotate, which drives the screw sleeve 22 and the magnetic positioning plate 23 to extend downward until the bottom end of the magnetic positioning plate 23 is exposed above the bottom end of the water level warning and measurement boat 1. Then, the traction rope 42 pulls the connecting sleeve 41 and the boat support plate 5 upward. The boat support plate 5 drags the water level warning and measurement boat 1 upward, and the staff removes the water level warning and measurement boat 1 from the boat support plate 5.
