Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a water level early warning device. Background Art

[0002] During marine construction, the tidal water level must be accurately judged to ensure the safety of the construction project. The height of the dangerous water level varies in different seasons. After the existing water level warning equipment is installed, the height cannot be adjusted, and the height of the water level monitoring and warning cannot be adjusted, so the scope of application is relatively small.

[0003] To this end, we propose a water level early warning device to solve the above problems. Summary of the invention

[0007] Preferably, the transmission mechanism comprises two sprockets, the two sprockets are coaxially fixedly connected to two threaded rods respectively, and the two sprockets are connected via a chain transmission.

[0008] Preferably, it also includes an early warning mechanism, which includes a float cavity arranged in the vertical plate, a float plate is slidably connected in the float cavity, a first metal plate is fixedly connected to the upper end of the float plate, an adjustment plate is provided in the float cavity, a second metal plate is fixedly connected to the lower end of the adjustment plate, an adjustment mechanism for adjusting the adjustment plate is provided in the float cavity, through holes are penetrated on the front and left sides of the float cavity, two pointers are slidably connected in the through holes on the front side, and the two pointers are respectively fixedly connected to the float plate and the adjustment plate, a display mechanism is provided on the vertical plate, and a depth detection mechanism is provided on the vertical plate.

[0009] Preferably, the adjusting mechanism includes a groove provided at the top inside the floating cavity. A bidirectional threaded rod is rotatably connected inside the groove. One end of the bidirectional threaded rod rotatably penetrates through the vertical plate and is coaxially and fixedly connected to a second turning handle. Two adjusting blocks are sleeved on the outer thread of the bidirectional threaded block. Both adjusting blocks are slidably connected to the inner side wall of the groove. The lower ends of the two adjusting blocks are rotatably connected to the same scissors. The lower end of the scissors is rotatably connected to two sliders. Both sliders are slidably connected to the upper end of the adjusting plate.

[0010] Preferably, threaded holes matching the bidirectional threaded rod are provided through both adjusting blocks, and the thread directions in the two threaded holes are opposite.

[0011] Preferably, the display mechanism includes a winding roller fixedly connected to the upper end of the vertical plate. A traction rope is wound around the winding roller. A pulley is fixedly connected to the lower end of the vertical plate. The lower end of the traction rope sequentially penetrates through the vertical plate, the pulley and the vertical plate and is fixedly connected to the lower end of the floating plate. A digital display meter is fixedly connected to the rear end of the winding roller. The detection shaft on the digital display meter is coaxially and fixedly connected to the winding roller. A warning horn is fixedly connected to the front end of the winding roller. The warning horn is electrically connected to both the first metal plate and the second metal plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By providing an adjusting mechanism, the first turning handle drives the two threaded rods to rotate. The two threaded rods drive the two threaded blocks to move. The two threaded blocks drive the vertical plate to rise and fall through the two connecting rods until it reaches a suitable position, so that the height of the installed water level warning device can be adjusted, and the applicable range is relatively wide;

[0017] 2. By setting up a warning mechanism, the top plate is driven to move by an electric telescopic rod until the top plate abuts against the bottom of the ocean shore. At this time, the real-time depth can be observed through the scale on the electric telescopic rod. By driving the bidirectional threaded rod to rotate with the second rotating handle, the bidirectional threaded rod drives two adjusting blocks to move relatively. The two adjusting blocks drive the adjusting plate to rise and fall through the scissors until it reaches the appropriate position. In different seasons, the height of the adjusting plate can be adjusted to adjust the dangerous warning water level, and the use effect is better. When the water level rises, the floating plate rises under the action of buoyancy. The floating plate drives the first metal plate to rise and pulls the traction rope. When the first metal plate abuts against the second metal plate, the power supply of the warning horn is connected, and the warning horn gives a warning. At the same time, the traction rope drags the winding roller to rotate, and the rotation distance of the winding roller is intuitively displayed in the digital display, which is more convenient to use.

[0018] The present invention can adjust the height of the water level warning device, has a wide range of applications and can adjust the dangerous water level, and has a good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
