Description

Technical Field

[0001] This utility model belongs to the field of water level measurement technology in water conservancy projects, and in particular relates to a water level measurement device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. In order to ensure the safety of reservoirs and prevent floods, it is necessary to monitor the reservoir water level. In summary, the existing technology has the following problems: Radar water level monitors for water conservancy projects usually refer to radar water level gauges or radar water level monitoring stations. They are devices that use radar technology to measure water levels and have the advantages of high precision and real-time monitoring. During installation, a base needs to be pre-embedded in the ground, and then the radar water level monitor is fixed to the top of the base with bolts. The bolt installation requires professional operation to ensure that the bolt position is accurate and the tightness is moderate. Since it is installed outdoors, the bolts may loosen, corrode or be damaged, resulting in unstable installation. However, the radar water level monitors used in existing water conservancy projects do not have a more stable component for installation on the ground. Therefore, a water level measuring device for water conservancy projects is proposed to solve the above problems. Utility Model Content

[0003] To address the problems of existing technologies, this utility model provides a water level measuring device for water conservancy projects. It offers the advantage of enabling more stable installation of radar water level monitors used in water conservancy projects on the ground. This solves the problem that existing radar water level monitors for water conservancy projects, typically referring to radar level gauges or radar water level monitoring stations, are devices that use radar technology to measure water levels. While they offer advantages such as high precision and real-time monitoring, installation requires pre-embedded bases in the ground, followed by bolts to fix the radar water level monitor to the top of the base. Bolt installation requires professional operation to ensure accurate bolt positioning and appropriate tightening. Because they are installed outdoors, bolts may loosen, corrode, or become damaged, leading to unstable installation. However, existing radar water level monitors used in water conservancy projects lack components for more stable ground installation.

[0004] This utility model is implemented as follows: a water level measuring device for water conservancy projects includes a radar water level monitor and a fixed shell. The bottom of the radar water level monitor is fixedly connected to the top of the fixed shell. A fixed outer shell is movably connected to the surface of the fixed shell, and the fixed outer shell is embedded in the ground. A fixing structure is provided in the inner cavity of the fixed shell.

[0005] As a preferred embodiment of this utility model, the fixing structure includes two fixing plates. The opposite sides of the two fixing plates penetrate the fixing shell and extend to the outer side of the inner cavity of the fixing shell. Two positioning square holes are opened on the surface of the fixing plates. Two springs are fixedly connected to the opposite sides of the two fixing plates. By setting the fixing structure, when the fixing shell and the radar water level monitor move to the top of the fixing shell, the fixing structure has a limiting effect on the position of the fixing shell and the radar water level monitor.

[0006] As a preferred embodiment of this utility model, the inner cavity of the fixed shell is fixedly connected with two positioning rods that cooperate with the positioning square holes. The surface of the positioning rods is movably connected to the inner cavity of the positioning square holes. By setting the positioning rods, when the fixed plate moves, it will drive the positioning square holes to move along the surface of the positioning rods. The cooperation between the positioning square holes and the positioning rods has a limiting effect on the movement position of the fixed plate.

[0007] In a preferred embodiment of this invention, a rotating extrusion frame is movably connected to the bottom of the inner cavity of the fixed shell via a rotating shaft, and an extrusion rod that works in conjunction with the rotating extrusion frame is fixedly connected to the top of the fixed plate. The surface of the extrusion rod is movably connected to the inner cavity of the rotating extrusion frame. By setting the rotating extrusion frame and the extrusion rod, when the rotating extrusion frame rotates, it can generate extrusion force on the extrusion rod, and the extrusion rod subjected to extrusion force can drive the fixed plate to move.

[0008] As a preferred embodiment of this utility model, the surface of the rotating extrusion frame has two control holes, and the inner cavity of the fixed shell is movably connected to two control folding blocks that cooperate with the control holes. The surface of the control folding blocks is movably connected to the inner cavity of the control holes, and the opposite sides of the two control folding blocks penetrate the fixed shell and extend to the outer side of the inner cavity of the fixed shell. By setting the control holes and control folding blocks, when the control folding blocks move, they can generate extrusion force on the control holes. The cooperation between the control folding blocks and the control holes can drive the rotating extrusion frame to rotate through the rotating shaft.

[0009] In a preferred embodiment of this invention, a limiting shell is fixedly connected to one side of each of the two control blocks. The inner cavity of the limiting shell is movably connected to a limiting inner rod that cooperates with the limiting shell. The surface of the limiting inner rod is fixedly connected to the inner cavity of the fixed shell. By setting the limiting shell and the limiting inner rod, when the control blocks move, the limiting shell will move along the surface of the limiting inner rod. The cooperation of the limiting shell and the limiting inner rod has a limiting effect on the movement position of the control blocks.

[0010] As a preferred embodiment of this utility model, the left and right sides of the inner cavity of the fixed outer shell are provided with a locking plate groove for use with the fixing plate. The surface of the fixing plate is in contact with the inner cavity of the locking plate groove. By providing the locking plate groove, when the fixed shell moves to the inner cavity of the fixed outer shell, the control block is released, and the restoring force generated by the spring returning to its shape will drive the fixing plate to be locked into the inner cavity of the locking plate groove. The cooperation between the fixing plate and the locking plate groove has a limiting effect on the position of the fixed shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing radar water level monitors in water conservancy projects, which typically refer to radar water level gauges or radar water level monitoring stations, by setting up a fixed structure, a fixed plate, a positioning square hole, a spring, and a plate groove in combination. These devices use radar technology to measure water levels and have the advantages of high precision and real-time monitoring. During installation, a base needs to be pre-embedded in the ground, and then bolts are used to fix the radar water level monitor to the top of the base. The bolt installation requires professional operation to ensure that the bolt position is accurate and the tightness is moderate. Since it is installed outdoors, the bolts may loosen, corrode, or be damaged, resulting in unstable installation. However, existing radar water level monitors used in water conservancy projects do not have a more stable component for installation on the ground.

[0013] 2. By setting a fixing structure, when the long rod is moved, it will drive the two fixing plates to move closer to each other. When the fixing plates move, they will drive the positioning square hole to move along the surface of the positioning square rod. At the same time, the force generated when the fixing plates move causes the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the fixing plates to be inserted into the inner cavity of the plate slot. The fixing structure has a limiting effect on the position of the fixing shell and the radar water level monitor. Attached Figure Description

Detailed Implementation

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a water level measuring device for water conservancy projects, including a radar water level monitor 1 and a fixed shell 2. The bottom of the radar water level monitor 1 is fixedly connected to the top of the fixed shell 2. A fixed outer shell 3 is movably connected to the surface of the fixed shell 2, and the fixed outer shell 3 is embedded in the ground. A fixing structure 4 is provided in the inner cavity of the fixed shell 2.

[0022] refer to Figure 4 The fixing structure 4 includes two fixing plates 401. The opposite sides of the two fixing plates 401 penetrate the fixing shell 2 and extend to the outer side of the inner cavity of the fixing shell 2. Two positioning square holes 402 are opened on the surface of the fixing plates 401. Two springs 403 are fixedly connected to the opposite sides of the two fixing plates 401.

[0023] The above solution is adopted: by setting the fixing structure 4, when the fixing shell 2 and the radar water level monitor 1 move to the top of the fixing shell 3, the fixing structure 4 has a limiting effect on the position of the fixing shell 2 and the radar water level monitor 1.

[0024] refer to Figure 4 The inner cavity of the fixed shell 2 is fixedly connected to two positioning rods 5 that cooperate with the positioning square hole 402. The surface of the positioning rods 5 is movably connected to the inner cavity of the positioning square hole 402.

[0025] The above solution is adopted: by setting the positioning rod 5, when the fixed plate 401 moves, it will drive the positioning hole 402 to move along the surface of the positioning rod 5. The cooperation between the positioning hole 402 and the positioning rod 5 has a limiting effect on the movement position of the fixed plate 401.

[0026] refer to Figure 3 The bottom of the inner cavity of the fixed shell 2 is movably connected to the rotating extrusion frame 6 via a rotating shaft. The top of the fixed plate 401 is fixedly connected to the extrusion rod 7, which is used in conjunction with the rotating extrusion frame 6. The surface of the extrusion rod 7 is movably connected to the inner cavity of the rotating extrusion frame 6.

[0027] The above solution is adopted: by setting a rotating extrusion frame 6 and an extrusion rod 7, when the rotating extrusion frame 6 rotates, it can generate extrusion force on the extrusion rod 7, and the extrusion rod 7 subjected to extrusion force can drive the fixed plate 401 to move.

[0028] refer to Figure 3 Two control holes 8 are provided on the surface of the rotating extrusion frame 6. Two control folding blocks 9 that cooperate with the control holes 8 are movably connected to the inner cavity of the fixed shell 2. The surface of the control folding blocks 9 is movably connected to the inner cavity of the control holes 8. The opposite sides of the two control folding blocks 9 penetrate the fixed shell 2 and extend to the outer side of the inner cavity of the fixed shell 2.

[0029] The above scheme is adopted: by setting control hole 8 and control folding block 9, when control folding block 9 moves, it can generate extrusion force on control hole 8. The cooperation between control folding block 9 and control hole 8 can drive the rotating extrusion frame 6 to rotate through the rotating shaft.

[0030] refer to Figure 3 Each of the two control folding blocks 9 is fixedly connected to a limiting shell 10 on one side opposite to the other. The inner cavity of the limiting shell 10 is movably connected to a limiting inner rod 11 that works in conjunction with the limiting shell 10. The surface of the limiting inner rod 11 is fixedly connected to the inner cavity of the fixed shell 2.

[0031] The above solution is adopted: by setting a limiting outer shell 10 and a limiting inner rod 11, when the control folding block 9 moves, it will drive the limiting outer shell 10 to move along the surface of the limiting inner rod 11. The cooperation of the limiting outer shell 10 and the limiting inner rod 11 has a limiting effect on the movement position of the control folding block 9.

[0032] refer to Figure 2 The left and right sides of the inner cavity of the fixed outer shell 3 are provided with card slots 12 that cooperate with the fixed card plate 401, and the surface of the fixed card plate 401 contacts the inner cavity of the card slot 12.

[0033] The above solution is adopted: by setting the card slot 12, when the fixed shell 2 moves into the inner cavity of the fixed shell 3, the control folding block 9 is released, and the restoring force generated by the spring 403 returning to its shape will drive the fixed card 401 to be inserted into the inner cavity of the card slot 12. The cooperation between the fixed card 401 and the card slot 12 has a limiting effect on the position of the fixed shell 2.

[0034] The working principle of this utility model:

[0035] When using the radar water level monitor 1 in a water conservancy project, which requires a more stable installation on the ground, the user first embeds the fixed housing 3 in the ground, and then pulls the control folding blocks 9 to one side opposite to each other. When the control folding blocks 9 move, they will cause the limiting housing 10 to move along the surface of the limiting inner rod 11. When the control folding blocks 9 move, they can generate a squeezing force on the control hole 8. The squeezing force on the control hole 8 will cause the rotating squeezing frame 6 to rotate along the surface of the squeezing rod 7 via the rotating shaft. The squeezing force generated by the rotating squeezing frame 6 on the squeezing rod 7 will cause the two squeezing rods 7 to move towards each other. When the squeezing rods 7 move, they will cause the two fixed plates 401 to move towards each other. When the two sides move closer together, the fixed plate 401 will move along the surface of the positioning square hole 402 along the positioning square rod 5. At the same time, the force generated by the movement of the fixed plate 401 will cause the spring 403 to undergo elastic deformation. When the fixed plate 401 moves completely into the inner cavity of the fixed shell 2, the fixed shell 2 will be moved into the inner cavity of the fixed outer shell 3. Then, the two control folding blocks 9 will be released. The restoring force generated by the spring 403 returning to its shape will drive the fixed plate 401 to be locked into the inner cavity of the plate slot 12. The cooperation of the fixed plate 401 and the plate slot 12 has a limiting effect on the position of the fixed shell 2 and the radar water level monitor 1. At this time, the radar water level monitor 1 used in water conservancy projects is more stably installed on the ground.

[0036] In summary, this water level measuring device for water conservancy projects, through the coordinated use of a fixed structure 4, a fixed clamping plate 401, a positioning square hole 402, a spring 403, and a clamping plate groove 12, solves the problem of existing radar water level monitors for water conservancy projects. These radar water level monitors, typically referring to radar water level gauges or radar water level monitoring stations, are devices that use radar technology to measure water levels. They offer advantages such as high precision and real-time monitoring. During installation, a base needs to be pre-embedded in the ground, and then bolts are used to fix the radar water level monitor to the top of the base. Bolt installation requires professional operation to ensure accurate bolt positioning and appropriate tightening. Since it is installed outdoors, the bolts may loosen, corrode, or be damaged, causing unstable installation. However, existing radar water level monitors used in water conservancy projects lack more stable components for ground installation.
