Description

Technical Field

[0001] This invention belongs to the field of water conservancy construction technology, specifically monitoring equipment for water conservancy projects. Background Technology

[0002] Water conservancy monitoring equipment is mainly used to monitor the water conservancy operation of rivers, lakes and reservoirs, and to promptly reflect the hydrological characteristics of each water area so that relevant departments can make arrangements to prevent flood disasters. Through various detectors, it detects digital information such as water temperature, humidity, wind speed, wind direction, rainfall, water quality, water flow velocity, water volume, video images or pictures, and then transmits the data to the receiving terminal via wireless transmission equipment.

[0003] For example, utility model CN217083882U discloses an intelligent water level monitoring device for water conservancy projects, relating to the technical field of water level monitoring equipment. It includes a hollow measuring rod with a floating plate that can slide up and down on its outer surface. A slider is slidably connected inside the hollow measuring rod. A laser sensor is installed on the top surface inside the hollow measuring rod. A top plate is welded to the top of the hollow measuring rod, and a measuring cabinet is installed on the upper surface of the top plate. An audible and visual alarm is installed on the right side of the measuring cabinet. The floating plate can rise and fall with changes in water level, synchronously driving the slider inside the hollow measuring rod to slide up and down. The laser sensor can monitor the distance between the laser sensor and the slider, thereby accurately measuring the water level data indirectly. The measured water level data can be displayed in real time on an LED display screen, and an audible and visual alarm can be automatically triggered when the water level reaches the warning level.

[0004] When the hollow measuring rod is inserted into the bottom of the water, the presence of underwater currents often causes the hollow measuring rod to become unstable under the impact of the currents, which is not conducive to the monitoring of the environment during water conservancy construction. Therefore, a monitoring device for water conservancy projects is proposed to solve the problems mentioned in the background art. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the problems mentioned in the background section, this invention provides a monitoring device for water conservancy projects, which solves the problem that existing water conservancy monitoring devices are unstable due to underwater current impacts.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a monitoring device for water conservancy projects, comprising a cone block, a hollow tube, a spring plate, and a spring. A ball-shaped tube is connected to the inner cavity of the cone block via a ball shaft. An intermediate shaft is movably engaged within the inner cavity of the hollow tube. Limiting rods are movably connected to both sides of the middle portion of the inner cavity of the intermediate shaft. A splined shaft is movably connected within the inner cavity of the cone block. A threaded tube is fixedly connected to the bottom of the splined shaft. A fixed roller is fixedly connected to the bottom of the threaded tube. A collar block is movably engaged at the bottom of the outer surface of the splined shaft. An annular spring plate is fixedly connected to the outer surface of the collar block. An intermediate ring block is movably engaged at the top of the inner cavity of the annular spring plate. A limiting block is movably engaged at equal angles within the inner cavity of the cone block. A shaped block is fixedly engaged at equal angles on the outer surface of the intermediate ring block. A slot is formed on the side of the shaped block away from the intermediate ring block.

[0009] Preferably, a spring is sleeved on the outer surface of the limiting rod, a water level buoyancy detection block is sleeved on the middle part of the outer surface of the intermediate shaft, spline sleeves are fixedly connected to the top and bottom of the outer surface of the hollow tube, a buoyancy block is movably engaged on the outer surface of the spline sleeve, and a convex ring block is provided in the lower middle part of the outer surface of the intermediate shaft.

[0010] Preferably, the bottom of the limiting rod is movably connected to the top of the inner cavity of the spherical tube, and the hollow tube is located directly above the cone block.

[0011] Preferably, the bottom of the outer surface of the intermediate shaft is movably connected to the inner cavity of the spherical tube. The diameter of the bottom of the intermediate shaft is equal to the diameter of the top of the spline shaft. The spline shaft is movably connected to the inner cavity of the spherical tube. It is worth noting that initially, the top of the outer surface of the spline shaft is movably engaged with the inner cavity of the spherical tube, at which point the spherical tube will be in a vertical state. This ensures that it is easy to insert the cone block into the bottom of the water initially. After the fixed roller drills into the bottom of the water, the spline shaft disengages from the inner cavity of the spherical tube, thereby resolving the spline shaft's fixing effect on the spherical tube. This allows the spherical tube to subsequently act as a buffer against the impact of the current, making the device more stable during use.

[0012] Preferably, the bottom of the limiting rod is fixedly connected to the inner cavity at the top of the spherical tube, and the outer surface of the limiting rod is movably connected to the inner cavity at the bottom of the hollow tube.

[0013] Preferably, the outer surface of the threaded tube is threadedly connected to the inner cavity of the cone block, the end of the annular spring sheet away from the collar block is fixedly connected to the intermediate ring block, and the fixed roller is movably connected to the inner cavity of the cone block.

[0014] Preferably, the irregularly shaped block is located inside the cavity of the cone block, and the irregularly shaped block is movably connected to the cavity of the cone block.

[0015] Preferably, the irregular block and the side of the irregular block near the limiting block are inclined, and the end of the limiting block near the spline shaft is inclined, and the limiting block and the irregular block cooperate with each other.

[0016] Preferably, the inside of the slot and the end of the limiting block near the spline shaft are engaged and snapped together, and the two ends of the spring sheet are fixedly connected to the cone block and the limiting block respectively, with the spring sheet located in the inner cavity of the cone block.

[0017] Preferably, the top and bottom of the spring are fixedly connected to the hollow tube and the intermediate shaft, respectively, and the convex ring block is located below the hollow tube.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention achieves excellent fixation through the cooperation of structures such as a conical block, annular spring sheet, irregular block, and limiting block. By inserting the bottom of the conical block into the bottom of the water and then pressing down on the intermediate shaft, the spline shaft moves downward, causing the threaded tube and fixed roller to move downward as well. As the threaded tube descends, it drives the fixed roller to rotate, allowing it to penetrate into the bottom of the water. Simultaneously, the rotation of the threaded tube also drives the collar block to rotate, compressing the annular spring sheet. When the fixed roller is compressed to its limit, the annular spring sheet rotates, causing the irregular block to rotate. Due to the cooperation between the irregular block and the limiting block, the limiting block moves away from the spline shaft, allowing it to insert laterally into the soil at the bottom of the water, thus providing a stable fixation for the bottom of the device.

[0021] This invention utilizes the cooperation of structures such as springs, spline sleeves, buoyancy blocks, and convex ring blocks to provide a device that effectively prevents the impact of underwater currents and maintains stability. After the fixed roller penetrates to the bottom of the water, one end of the spline shaft will detach from the inner cavity of the spherical tube and be completely inside the inner cavity of the conical block. Simultaneously, due to the spring tension, the intermediate shaft will return to its original position. If an underwater current is encountered, the hollow tube and the spherical tube will tilt under the impact of the current. If the tilt of the hollow tube and the spherical tube is too large, the convex ring block will push the hollow tube, causing the hollow tube and the intermediate shaft to move upward, compressing the spring and thus buffering the impact of the water flow on the hollow tube. In addition, the design of the buoyancy block makes the upper and middle parts of the device more stable, keeping the hollow tube vertical, which facilitates the device's water level detection.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 6As shown, the present invention provides a monitoring device for water conservancy projects, including a cone block 1, a hollow tube 2, a spring plate 14, and a spring 16. A ball shaft 4 is connected to the inner cavity of the cone block 1. An intermediate shaft 3 is movably engaged within the inner cavity of the hollow tube 2. Limiting rods 5 are movably connected to both sides of the middle part of the inner cavity of the intermediate shaft 3. A splined shaft 6 is movably connected within the inner cavity of the cone block 1. A threaded tube 7 is fixedly connected to the bottom of the splined shaft 6. A fixed roller 8 is fixedly connected to the bottom of the threaded tube 7. A collar block 9 is movably engaged at the bottom of the outer surface of the splined shaft 6. An annular spring plate 10 is fixedly connected to the outer surface of the collar block 9. An intermediate ring block 11 is movably engaged at the top of the inner cavity of the annular spring plate 10. A limiting block 12 is movably engaged at an annular angle within the inner cavity of the cone block 1. A shaped block 13 is fixedly connected at an annular angle on the outer surface of the intermediate ring block 11. The shaped block 13 is located away from the intermediate ring block 11. A slot 15 is provided on one side; by inserting the bottom of the conical block 1 into the bottom of the water, and then pressing down on the intermediate shaft 3, the spline shaft 6 will move downward, and drive the threaded tube 7 and the fixed roller 8 to move downward. As the threaded tube 7 descends, it drives the fixed roller 8 to rotate, so that the fixed roller 8 penetrates into the bottom of the water. At the same time as the threaded tube 7 rotates, it also drives the collar block 9 to rotate, so that the annular spring plate 10 is compressed. When the fixed roller 8 is compressed to the limit, the annular spring plate 10 will rotate, thereby driving the irregular block 13 to rotate. At this time, due to the cooperation between the irregular block 13 and the limiting block 12, the limiting block 12 will move away from the spline shaft 6, so that the limiting block 12 is inserted laterally into the soil at the bottom of the water, thereby playing a stable fixing role at the bottom of the device.

[0031] like Figure 1 ,picture, Figure 3 , Figure 5As shown, a spring 16 is sleeved on the outer surface of the limiting rod 5, a water level buoyancy detection block 17 is sleeved on the middle part of the outer surface of the intermediate shaft 3, a spline sleeve 18 is fixedly connected to the top and bottom of the outer surface of the hollow tube 2, a buoyancy block 19 is movably engaged on the outer surface of the spline sleeve 18, a convex ring block 20 is provided in the lower middle part of the outer surface of the intermediate shaft 3, the top and bottom of the spring 16 are fixedly connected to the hollow tube 2 and the intermediate shaft 3 respectively, and the convex ring block 20 is located below the hollow tube 2; after drilling to the bottom of the water through the fixed roller 8, at this time one end of the top of the spline shaft 6 will detach from the inner cavity of the ball tube 4 and be completely inside the inner cavity of the cone block 1, and so on. Due to the tension of spring 16, the intermediate shaft 3 will return to its original position. If an underwater current is encountered, the hollow tube 2 and the spherical tube 4 will tilt under the impact of the current. If the tilt of the hollow tube 2 and the spherical tube 4 is too large, the convex ring block 20 will push the hollow tube 2, causing the hollow tube 2 and the intermediate shaft 3 to move upward, compressing the spring 16. This buffers the impact of the water flow on the hollow tube 2. At the same time, in conjunction with the design of the buoyancy block 19, the upper part of the device becomes more stable, keeping the hollow tube 2 vertical, which facilitates the device's detection of the water level.

[0032] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the bottom of the limiting rod 5 is movably connected to the top of the inner cavity of the ball tube 4, the hollow tube 2 is located directly above the cone block 1, the bottom of the outer surface of the intermediate shaft 3 is movably connected to the inner cavity of the ball tube 4, the diameter of the bottom of the intermediate shaft 3 is equal to the diameter of the top of the spline shaft 6, the spline shaft 6 is movably connected to the inner cavity of the ball tube 4, the bottom of the limiting rod 5 is fixedly connected to the inner cavity of the top of the ball tube 4, and the outer surface of the limiting rod 5 is movably connected to the inner cavity of the bottom of the hollow tube 2; through the design of the limiting rod 5, the connection between the ball tube 4 and the hollow tube 2 is achieved.

[0033] It is worth noting that initially, the top of the outer surface of the spline shaft 6 is engaged with the inner cavity of the ball tube 4, at which point the ball tube 4 will be in a vertical position. This ensures that the cone block 1 can be easily inserted into the bottom of the water initially. After the fixing roller 8 is inserted into the bottom of the water, the spline shaft 6 disengages from the inner cavity of the ball tube 4, thus resolving the fixing effect of the spline shaft 6 on the ball tube 4. This allows the ball tube 4 to subsequently act as a buffer against the impact of the hollow tube 2 on the current, thereby making the device more stable during use.

[0034] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the outer surface of the threaded tube 7 is threadedly connected to the inner cavity of the cone block 1. The end of the annular spring plate 10 away from the collar block 9 is fixedly connected to the intermediate ring block 11. The fixed roller 8 is movably connected to the inner cavity of the cone block 1. The shaped block 13 is located in the inner cavity of the cone block 1 and is movably connected to the inner cavity of the cone block 1. The side of the shaped block 13 near the limiting block 12 is inclined. The end of the limiting block 12 near the spline shaft 6 is also inclined. The limiting block 12 and the shaped block 13 cooperate. The inside of the slot 15 and the end of the limiting block 12 near the spline shaft 6 are engaged and snapped together. The two ends of the spring plate 14 are respectively connected to the cone block 1 and the limiting block 12. The block 12 is fixedly connected, and the spring plate 14 is located in the inner cavity of the cone block 1. Through the cooperation between the threaded tube 7 and the inner cavity of the cone block 1, the threaded tube 7 has a tendency to rotate while moving downward, so that the fixed roller 8 is more easily and more stably fixed when drilling into the bottom of the water. At the same time, through the cooperation between the limiting block 12 and the irregular block 13, the irregular block 13 is squeezed against the limiting block 12 when rotating, so that the end of the limiting block 12 near the spline shaft 6 is inserted into the groove 15, thereby fixing the limiting block 12. Finally, the limiting block 12 plays a role in increasing the stability of the cone block 1 in the vertical direction.

[0035] It is worth noting that: since the threaded tube 7 needs to rotate multiple times when it moves downward, but the shaped block 13 does not need to rotate multiple times, the design of the annular spring plate 10 will compress the annular spring plate 10 by rotating the spline shaft 6 and the collar block 9. Thus, when the elastic force of the annular spring plate 10 after being compressed is greater than the elastic force of the spring plate 14, the annular spring plate 10 will drive the shaped block 13 to rotate and squeeze the restricting block 12 to move outward.

[0036] Working principle and usage process of this invention:

[0037] First, the operator inserts the device into the water, so that the bottom of the cone block 1 is inserted into the bottom. Then, the operator presses down on the intermediate shaft 3, which causes the spline shaft 6 to move downward, and drives the threaded tube 7 and the fixed roller 8 to move downward. At this time, due to the cooperation between the cone block 1 and the threaded tube 7, the threaded tube 7 will rotate as it descends, which in turn drives the fixed roller 8 to rotate as it descends, so that the fixed roller 8 penetrates into the bottom of the water. At the same time as the threaded tube 7 rotates, it will also drive the collar block 9 to rotate, which will compress the annular spring plate 10. When the fixed roller 8 is compressed to its limit, the annular spring plate 10 will rotate, which will drive the irregular block 13 to rotate. At this time, due to the cooperation between the irregular block 13 and the limiting block 12, the limiting block 12 will move away from the spline shaft 6, so that the limiting block 12 is inserted laterally into the soil at the bottom of the water, thereby playing a stable fixing role for the bottom of the device.

[0038] After the fixed roller 8 penetrates to the bottom of the water, the top end of the spline shaft 6 will detach from the inner cavity of the ball tube 4 and be completely inside the inner cavity of the cone block 1. At the same time, due to the tension of the spring 16, the intermediate shaft 3 will be reset. If an underwater current is encountered, the hollow tube 2 and the ball tube 4 will tilt under the impact of the current. If the tilt of the hollow tube 2 and the ball tube 4 is too large, the convex ring block 20 will push the hollow tube 2. At the same time, with the limiting action of the limiting rod 5, the hollow tube 2 and the intermediate shaft 3 will move upward, causing the spring 16 to be compressed, thus buffering the impact of the water flow on the hollow tube 2. In addition, with the design of the buoyancy block 19, the upper part of the device becomes more stable, keeping the hollow tube 2 in a vertical state, so as to facilitate the detection of the water level.
