Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically a precise water level monitoring device for water conservancy. Background Technology

[0002] The transmission is the "intelligent brain" of a car's drivetrain, achieving three core functions by adjusting gear ratios: power matching, reversing, and neutral disengagement. Different types of transmissions have different working principles, but their basic goal is to adjust the engine's output speed and torque by changing the gear ratios.

[0003] In response to the above and existing related technologies: During the construction of water conservancy projects, it is necessary to monitor the water level. Generally, radar water level gauges are used for accurate detection. However, oil and algae floating on the water surface for a long time will absorb or scatter radar waves, resulting in weakened signal strength or even failure to identify effective reflected waves, leading to data loss or measurement drift. Therefore, a precise water level monitoring device is proposed to address the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The water level precision monitoring device of this utility model includes a support rod and an isolation device. A connecting rod is fixedly connected to the surface of the support rod, and a water level gauge is fixedly connected to the side wall of the connecting rod. The isolation device is disposed on the surface of the support rod and includes a fixing frame. The fixing frame is sleeved on the surface of the support rod, and a sliding rod is slidably connected to the inner wall of the fixing frame. A frame is fixedly connected to the bottom end of the sliding rod, and a limit cover is fixedly connected to the upper surface of the frame. The frame is inserted into the water body, and part of the limit cover is located on the water surface. By setting the fixing frame, sliding rod, frame and limit cover, the influence of floating objects on the water level gauge monitoring can be reduced.

[0006] Preferably, a limiting frame is fixedly connected to the side wall of the fixing frame. The limiting frame is sleeved on the surface of the support rod. After the fixing frame is attached to the support rod, the limiting frame and the fixing frame are fixed. The position of the fixing frame can be restricted by setting the limiting frame.

[0007] Preferably, the inner walls of the fixing frame and the slide rod are threaded with positioning pins. After the slide rod moves to a suitable height, the positioning pins are rotated to the inner walls of the fixing frame and the slide rod. The positioning pins can limit the height of the slide rod.

[0008] Preferably, the slide rod has multiple positioning holes on its surface, the positioning pin passes through the inner surface of the positioning holes of the slide rod, the fixing frame has a sliding hole on its surface, and the slide rod surface and the inner wall of the sliding hole of the fixing frame are slidably connected. When the slide rod moves, the slide rod slides on the inner wall of the sliding hole of the fixing frame. The sliding hole facilitates the movement of the slide rod.

[0009] Preferably, a reinforcing frame is fixedly connected to the surface of the slide rod and the frame. When the frame is under force, the frame will transfer the force to the reinforcing frame, which can increase the strength of the connection between the slide rod and the frame.

[0010] Preferably, the bottom end of the frame is provided with a blocking device, the blocking device including a fixed frame, the fixed frame is fitted on the surface of the frame, the fixed frame and the inner wall of the frame are threadedly connected with multiple fixing pins, and the bottom end of the fixed frame is fixedly connected with a net, which will penetrate into the water. By setting the fixed frame, fixing pins and net, the contact between underwater objects and the water surface at the test location can be reduced.

[0011] Preferably, each of the four corners of the bottom of the net is fixedly connected with a connecting rope, and the bottom of the connecting rope is fixedly connected with a counterweight. When the net moves, the counterweight and the connecting rope will fall, thereby opening the net. By setting the connecting rope and the counterweight, the net can be easily opened.

[0012] The advantages of this utility model are:

[0013] 1. In this utility model, when a water level meter is needed, the fixing frame and the limiting frame are fixed to the surface of the support rod. Then, the sliding rod is pushed to slide on the inner wall of the sliding hole of the fixing frame. When the sliding rod slides, it will drive the frame and the limiting cover to move. The frame will be inserted into the water, and the limiting cover will float on the water surface. After the sliding rod slides to the appropriate position, the positioning pin is rotated to the inner wall of the fixing frame and the inner wall of the positioning hole of the sliding rod. When the frame is under force, the frame will transmit the force to the reinforcing frame. By setting the entire device, floating objects can be blocked, reducing the situation where floating objects float to the measured point and affect the water level meter monitoring.

[0014] 2. When using the frame, the fixed frame is attached to the frame, and then the fixing pin is rotated to the fixed frame and the inner wall of the frame. When the frame moves down, the frame drives the fixed frame, the net, the connecting rope and the counterweight into the water. The counterweight will cause the net to unfold due to its own weight. By setting the whole device, the situation of objects in the water drifting below the measured point can be reduced, thereby increasing the accuracy of water level detection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5. A precise water level monitoring device includes a support rod 1 and an isolation device 4. A connecting rod 2 is fixedly connected to the surface of the support rod 1, and a water level gauge 3 is fixedly connected to the side wall of the connecting rod 2. The isolation device 4 is disposed on the surface of the support rod 1 and includes a fixing frame 41. The fixing frame 41 is fitted onto the surface of the support rod 1, and a sliding rod 42 is slidably connected to the inner wall of the fixing frame 41. A frame 43 is fixedly connected to the bottom end of the sliding rod 42, and a limit cover 44 is fixedly connected to the upper surface of the frame 43. During operation, the fixing frame 41 is fitted onto the surface of the support rod 1, and then the sliding rod 42 is pushed to move the frame 43 and the limit cover 44. The frame 43 is inserted into the water body, and part of the structure of the limit cover 44 is located on the water surface. By setting the fixing frame 41, the sliding rod 42, the frame 43, and the limit cover 44, the influence of floating objects on the water level gauge 3 can be reduced.

[0024] The side wall of the fixed frame 41 is fixedly connected to the limiting frame 45, which is sleeved on the surface of the support rod 1. During operation, the limiting frame 45 and the fixed frame 41 are fixed, and the position of the fixed frame 41 can be restricted by setting the limiting frame 45.

[0025] The inner walls of the fixed frame 41 and the slide rod 42 are threaded with positioning pins 46; during operation, the positioning pins 46 are rotated to the inner walls of the fixed frame 41 and the slide rod 42, and the positioning pins 46 can limit the height of the slide rod 42.

[0026] The slide rod 42 has multiple positioning holes 47 on its surface. The positioning pin 46 passes through the inner surface of the positioning holes 47 of the slide rod 42. The fixing frame 41 has a sliding hole 48 on its surface. The surface of the slide rod 42 and the inner wall of the sliding hole 48 of the fixing frame 41 are slidably connected. During operation, the slide rod 42 slides on the inner wall of the sliding hole 48 of the fixing frame 41. When the positioning pin 46 rotates, the positioning pin 46 will rotate to the inner wall of the positioning hole 47. The sliding hole 48 facilitates the movement of the slide rod 42.

[0027] A reinforcing frame 49 is fixedly connected to the surfaces of the slide rod 42 and the frame 43. During operation, the frame 43 transmits force to the reinforcing frame 49, which increases the strength of the connection between the slide rod 42 and the frame 43.

[0028] The bottom end of the frame 43 is provided with a blocking device 5, which includes a fixed frame 51. The fixed frame 51 is fitted onto the surface of the frame 43. The fixed frame 51 and the inner wall of the frame 43 are threadedly connected with multiple fixing pins 52. The bottom end of the fixed frame 51 is fixedly connected with a net 53. During operation, the fixed frame 51 is fitted against the frame 43, and then the fixing pins 52 are rotated to the inner wall of the fixed frame 51 and the frame 43. The net 53 will then sink into the water. By setting the fixed frame 51, fixing pins 52 and net 53, the contact between underwater objects and the water surface at the test location can be reduced.

[0029] The bottom of the net 53 is fixedly connected to four corners with connecting ropes 54, and the bottom of the connecting ropes 54 is fixedly connected to counterweights 55. When working, the counterweights 55 and connecting ropes 54 will fall, thereby opening the net 53. The net 53 can be easily opened by setting the connecting ropes 54 and counterweights 55.

[0030] Working principle: When the water level gauge 3 needs to be used, the fixing frame 41 and the limiting frame 45 are fixed to the surface of the support rod 1. Then, the sliding rod 42 is pushed to slide on the inner wall of the sliding hole 48 of the fixing frame 41. When the sliding rod 42 slides, it will drive the frame 43 and the limiting cover 44 to move. The frame 43 will be inserted into the water, and the limiting cover 44 will float on the water surface. After the sliding rod 42 slides to the appropriate position, the positioning pin 46 is rotated to the inner wall of the fixing frame 41 and the inner wall of the positioning hole 47 of the sliding rod 42. When the frame 43 is under force, the frame 43 transmits the force to the reinforcing frame 49. By setting the entire device, floating objects can be blocked, reducing the impact of floating objects on the water level gauge 3 monitoring when they float to the measured point. When using the frame 43, the fixing frame 51 is attached to the frame 43, and then the fixing pin 52 is rotated to the inner wall of the fixing frame 51 and the frame 43. When the device moves downward, the frame 43 drives the fixed frame 51, the net 53, the connecting rope 54 and the counterweight 55 into the water. The counterweight 55 will cause the net 53 to unfold due to its own weight. By setting up the entire device, the occurrence of objects in the water drifting below the measured point can be reduced, thereby increasing the accuracy of water level detection.
