DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] like Figure 1-4 As shown, in this embodiment, a deep foundation pit water level monitoring device for a water conservancy and hydropower project includes a main body 1 and a support assembly 2, wherein the support assembly 2 is arranged outside the main body 1;

[0025] The support assembly 2 includes a plate body 201, a hydraulic rod 203, a first connecting rod 205, a third connecting rod 207 and a pressure feedback device 209; the plate body 201 is fixedly connected to the outer side of the main body 1, and a slide groove 202 is provided on the plate body 201; the hydraulic rod 203 is fixedly arranged on the outer side of the main body 1, and the driving end of the hydraulic rod 203 is fixedly connected to a slider 204, and the slider 204 is slidably connected in the slide groove 202; the first connecting rod 205 is rotatably connected to the outer end of the slider 204, and one side of the first connecting rod 205 is rotatably connected to the second connecting rod 206, and one end of the second connecting rod 206 is rotatably connected to the plate body 201; two third connecting rods 207 are rotatably connected to one end of the first connecting rod 205 and the second connecting rod 206, one end of the two third connecting rods 207 is rotatably connected, and the connection between the two third connecting rods 207 is rotatably connected to a rotating block 208; the pressure feedback device 209 is fixedly connected to one end of the rotating block 208.

[0026] During the specific implementation, the device is hoisted into the foundation pit through the traction rope 10, and then the hydraulic rod 203 is started according to the size of the foundation pit. The hydraulic rod 203 drives the slider 204 to slide in the slide groove 202. The sliding of the slider 204 drives the first connecting rod 205 to rotate, and the first connecting rod 205 links the second connecting rod 206. The first connecting rod 205 and the second connecting rod 206 rotate, driving the two third connecting rods 207 to rotate. The rotation of the two third connecting rods 207 will drive the rotating block 208 to translate, that is, drive the pressure feedback device 209 to extend and press against the inner wall of the foundation pit. The pressure feedback device 209 is fed back to the controller by pressure. The controller controls the hydraulic rod 203 to stop operating, and the four support components 2 are divided into two relative groups. One group of support components 2 in the X-axis direction is first extended to initially press the device against the foundation pit, and then the other group of support components 2 in the Y-axis direction is started. In this way, the device can be fixed in the foundation pit. At this time, the monitor 7 can maintain a stable state and continuously monitor.

[0027] In addition, it should be noted that a controller is provided in the main body 1, and the controller, the monitor 7 and the pressure feedback device 209 are existing technologies and will not be described in detail.

[0028] Furthermore, by providing a fixing rod 3, the hydraulic rod 203 can be fixed, and by providing a first rotating shaft 4 and a second rotating shaft 5, they can act as a fulcrum to facilitate rotation, and by providing an anti-skid pad 6, the friction force can be enhanced.

[0029] Furthermore, by providing the connecting ring 8, the connecting line 9 and the traction rope 10, the supporting assembly 2 can be hoisted into the foundation pit.

[0030] Furthermore, when the foundation pit is too large and the device cannot be fixed inside it, the four support components 2 can be extended. Since the main body 1, the first connecting rod 205, the second connecting rod 206 and the third connecting rod 207 are all made of polyethylene material, the polyethylene material has a low density and high hardness and can float on the water. By unfolding all four support components 2 on the water surface, the stability can be enhanced and the sustainability effect can be improved.

[0031] Working principle: First, the device is hoisted into the foundation pit through the traction rope 10, and then the hydraulic rod 203 is started according to the size of the foundation pit. The hydraulic rod 203 drives the slider 204 to slide in the slide groove 202. The sliding of the slider 204 drives the first connecting rod 205 to rotate. The first connecting rod 205 links the second connecting rod 206. The first connecting rod 205 and the second connecting rod 206 rotate, driving the two third connecting rods 207 to rotate. The rotation of the two third connecting rods 207 will drive the rotating block 208 to translate, that is, drive the pressure feedback device 209 to extend and press against the inner wall of the foundation pit. The pressure feedback device 209 receives the pressure feedback to the controller, and the controller controls the hydraulic rod 203 to stop operating, and the four support components 2 , divided into two relative groups, one group of support components 2 in the X-axis direction is stretched out first, and the device is initially placed in the foundation pit, and then the other group of support components 2 in the Y-axis direction is started, so that the device can be fixed in the foundation pit. At this time, the monitor 7 can maintain a stable state and continuously monitor. When the foundation pit is too large and the device cannot be fixed inside it, the four support components 2 can be stretched out. Since the main body 1, the first connecting rod 205, the second connecting rod 206 and the third connecting rod 207 are all made of polyethylene material, the polyethylene material has a low density and high hardness and can float on the water surface. When all four support components 2 are deployed on the water surface, the stable state can be enhanced and the sustainability effect can be improved.
