Description

Technical Field

[0001] The present invention relates to the field of water level measurement, and in particular to a water level measurement device based on the Internet of Things. Background Art

[0002] Compared with traditional water level measurement methods, water level measurement devices based on the Internet of Things have advantages such as real-time, accuracy, remote monitoring and flexible configuration. However, because the measuring end of the measuring device needs to be put into the water level observation hole, in actual operation, when the water level observation hole has a small aperture, large water droplets will form on the inner wall of the observation hole. At this time, when the measuring end contacts these water droplets, an alarm will be issued, giving the operator wrong instructions, which will lead to inaccurate final measurement results.

[0003] Moreover, after the measuring end contacts the water body, the dirt on the surface of the water body will clog the diversion hole at the head of the measuring end, which will not only affect the measurement results but may even make the measurement invalid. Therefore, the traditional water level measuring device requires the operator to pre-clean the water level observation hole before putting it into the water level observation hole to prevent the debris in the water level observation hole from affecting the measurement of the measuring end.

[0004] At the same time, since the immersion water level sensor measures the water level based on the static pressure of the measured liquid being proportional to the height of the liquid, when the sensor is placed vertically, it can accurately measure the height of the water level. On the contrary, if the end of the sensor is tilted, the pressure it receives on the liquid surface will no longer be completely determined by the water level, but will also be affected by the change in the gravity component caused by the tilt angle, which will cause a deviation in the corresponding relationship between the pressure value measured by the sensor and the actual water level. Therefore, the traditional water level measurement device requires the operator to adjust the measuring end in real time during the lowering process to prevent the measuring end from tilting, and to improve the accuracy of the results through multiple measurements.

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] refer to Figures 1 to 9 A water level measuring device based on the Internet of Things includes a measuring device body 1, the measuring device body 1 includes a bearing seat 4, a measuring rope 2 and a measuring end 3, one end of the measuring rope 2 is wound and connected with the rotating shaft of the bearing seat 4, and the measuring end 3 is fixedly connected with the other end of the measuring rope 2 (such as Figure 5 shown), and also includes:

[0035] The stabilization component 6 includes a protective liner 7, a waterproof shell 10 and a plurality of tightening mechanisms 30. The protective liner 7 is sleeved on the outside of the measuring end 3 and is fixedly connected to the measuring rope 2. The waterproof shell 10 is coaxially fixedly sleeved on the outside of the protective liner 7. The plurality of tightening mechanisms 30 are arranged in an array with equal angles along the circumferential direction of the waterproof shell 10. The plurality of tightening mechanisms 30 are respectively fixedly connected to the waterproof shell 10.

[0036] The tightening mechanism 30 includes two tightening wheels 38, which are respectively arranged on the sides of the protective liner 7 and can be tightened against the hole wall of the observation tube 5;

[0037] The water-drawing mechanism 40 is connected to the lower end of the protective inner liner 7, and includes a water-drawing tube 41 and an intercepting cover 43 loaded with a counterweight 45. The water-drawing tube 41 is fixedly connected to the lower end of the protective inner liner 7 and is sleeved on the outside of the measuring end 3. The intercepting cover 43 is arranged on the lower end of the waterproof outer shell 10 and is sleeved on the outside of the water-drawing tube 41.

[0038] When the device is in operation, the operator places the measuring device body 1 on the upper end of the observation tube 5, and then starts the measuring device body 1 to drop the measuring end 3 along the observation tube 5. During this process, the tightening mechanism 30 connected to the waterproof shell 10 will start and drive the corresponding tightening wheel 38 to press against the inner wall of the waterproof shell 10. At this time, the measuring end 3 can move along the observation tube 5 without deflection, thereby ensuring the accuracy of the measurement result. As the measuring end 3 moves downward, until the water body passes through the interception cover 43 and enters the water pumping tube 41, the water body contacts the measuring end 3 in the water pumping tube 41, and the measuring end 3 feeds back the signal to the controller in the measuring device body 1 (wherein the measuring end 3 is integrated with a immersion water level sensor, and the water level is measured based on the static pressure of the measured liquid being proportional to the height of the liquid). After the controller is electrically connected to the Internet of Things, it can record this data, thereby realizing the collection of water level measurement data.

[0039] In order to supplement the specific structure of the water-drawing mechanism 40, the following features are also specifically provided:

[0040] The water-drawing cylinder 41 is formed with a plurality of water inlet holes 42 at equal angles along the circumferential direction, and the interception cover 43 is formed with a plurality of filter holes 44 at equal angles along the circumferential direction, and the plurality of filter holes 44 can intercept debris in the water body. After the interception cover 43 is put into the water body, as the water body passes through the interception cover 43 and enters the water-drawing cylinder 41, the debris in the water body will be intercepted by the filter holes 44, and then the water body will pass through the water inlet holes 42 and enter the water-drawing cylinder 41, until the water body contacts the measuring end 3, and the measuring end 3 feeds back the signal to the controller in the measuring device body 1, and the controller can record this data after being electrically connected to the Internet of Things, thereby realizing the collection of water level measurement data.

[0041] In order to supplement the specific structure of the stabilization component 6, the following features are also specifically provided:

[0042] The stabilization component 6 also includes a bearing top plate 8, a sliding support plate 11, a sliding pin 12, two first magnetic disks 13 and two second magnetic disks 14. The bearing top plate 8 is fixedly connected to the upper end of the protective liner 7. The two ends of the sliding support plate 11 are respectively slidably connected to the bearing seat 4 through slide rails. The sliding pin 12 is fixedly connected to the lower end of the middle part of the sliding support plate 11. A positioning hole 9 corresponding to the sliding pin 12 is formed on the bearing top plate 8. The sliding pin 12 can be slidably connected to the positioning hole 9 (such as Fig. 9 As shown), the two first magnetic disks 13 are symmetrically arranged on both sides of the sliding pin 12 and are respectively fixedly connected to the sliding support plate 11, and the two second magnetic disks 14 are respectively fixedly connected to the upper end of the supporting top plate 8 and are attracted to the two first magnetic disks 13 by magnetic force. When the measuring rope 2 is lowered, the first magnetic disk 13 and the second magnetic disk 14 attract each other, and the sliding support plate 11 and the supporting top plate 8 will move downward at the same time. At this time, the first magnetic disk 13 and the second magnetic disk 14 are connected under the action of magnetic force, and when the sliding support plate 11 and the supporting top plate 8 continue to move downward until the sliding support plate 11 collides with the upper end of the observation tube 5, since the stabilization component 6 connected to the supporting top plate 8 has inertia at this time, when the sliding support plate 11 and the upper end of the observation tube 5 are abutted, the two first magnetic disks 13 connected to the sliding support plate 11 stop moving, and when the inertia force of the two second magnetic disks 14 connected to the supporting top plate 8 is greater than the magnetic force between the first magnetic disk 13 and the second magnetic disk 14, the first magnetic disk 13 will be separated from the second magnetic disk 14, and at this time the sliding pin 12 and the positioning hole 9 are separated.

[0043] During this process, in order to ensure that the first disk 13 and the second disk 14 can be separated, the operator needs to control the distance between the sliding support plate 11 and the supporting top plate 8 relative to the upper end of the observation tube 5, so as to provide greater gravitational potential energy for the sliding support plate 11 and the supporting top plate 8, and ensure that when the sliding support plate 11 collides with the upper end of the observation tube 5, the supporting top plate 8 will continue to move downward at a high speed due to inertia, thereby generating a greater relative movement trend.

[0044] In order to supplement other structures in the stabilization component 6 when the first disk 13 and the second disk 14 are separated, the following features are also specifically provided:

[0045] The stabilization component 6 also includes a traction rack 15, a positioning bolt 16, a traction spring 17, a positioning baffle 18 and a leak-proof mechanism 19. The traction rack 15 is slidably arranged on the upper end of the bearing top plate 8. The positioning bolt 16 is horizontally fixedly connected to the side of the traction rack 15 close to the sliding pin 12. The positioning bolt 16 can abut against the sliding pin 12. One end of the traction spring 17 is fixedly connected to the traction rack 15. The positioning baffle 18 is fixedly connected to the upper end of the bearing top plate 8 and to the other end of the traction spring 17. The leak-proof mechanism 19 is arranged at the lower end of the bearing top plate 8 and is connected to the positioning hole 9. When the first magnetic disk 13 and the second magnetic disk 14 are attracted to each other, the traction rack 15 will abut against the sliding pin 12 through the positioning bolt 16. At this time, the traction rack 15 will not be displaced. When the sliding pin 12 and the positioning hole 9 are separated, the traction rack 15 will move toward the positioning baffle 18 under the action of the traction spring 17.

[0046] During this process, in order to prevent the positioning bolt 16 and the sliding pin 12 from being too tight under the action of the traction spring 17, a ball or roller should be added to the side of the sliding pin 12 close to the positioning bolt 16 according to the specific weight of the stabilization component 6 to reduce the friction between the sliding pin 12 and the positioning bolt 16, so as to facilitate the rapid separation of the positioning bolt 16 and the sliding pin 12.

[0047] In order to supplement the specific structure of the anti-leakage mechanism 19, the following features are also specifically provided:

[0048] The anti-leakage mechanism 19 also includes a lifting pin 20, an adapter cover 21, a lifting tension spring 22, a lifting frame 23, a lifting sleeve 24 and a lifting baffle 25. The lifting pin 20 is arranged at the lower end of the bearing top plate 8 and is coaxially arranged with the positioning hole 9. The lifting sleeve 24 is coaxially sleeved on the outside of the lifting pin 20, and the lifting baffle 25 is fixedly connected to the upper end of the lifting sleeve 24. The adapter cover 21 is coaxially sleeved on the outside of the lifting pin 20. The lifting baffle 25 is coaxially slidably connected with the adapter cover 21. The lifting frame 23 is sleeved on the outside of the lifting pin 20 and is fixedly connected to the bearing top plate 8. The lifting tension spring 22 is sleeved on the outside of the lifting pin 20. The upper end of the lifting tension spring 22 is fixedly connected to the bearing top plate 8, and the lower end is fixedly connected to the lifting sleeve 24. The lower end of the lifting frame 23 can be against the lifting baffle 25 after the lifting pin 20 moves upward. When the sliding pin 12 and the positioning hole 9 are separated, the lifting pin 20 will move upward under the action of the lifting tension spring 22 until the lifting pin 20 completes the blocking of the positioning hole 9. During this process, the lifting frame 23 and the lifting baffle 25 can offset each other to limit the movement range of the sliding pin 12, thereby preventing the upper end of the lifting pin 20 from extending too far out of the positioning hole 9.

[0049] In order to provide power to the tightening mechanism 30, the following features are also specifically provided:

[0050] The stabilization component 6 also includes a total driving gear 26, a transfer gear 27, a transfer gear ring 28, a tightening sleeve 39 and two tightening gear rings 29. The total driving gear 26 is rotationally connected to the load-bearing top plate 8 and meshes with the traction rack 15. The transfer gear 27 is rotationally connected to the lower end of the load-bearing top plate 8 and is coaxially fixedly connected to the total driving gear 26. The transfer gear ring 28 is rotationally connected to the lower end of the load-bearing top plate 8 coaxially. The transfer gear 27 meshes with the transfer gear ring 28. The two tightening gear rings 29 are symmetrically rotatably arranged at both ends of the protective inner liner 7. The tightening sleeve 39 is coaxially rotatably sleeved on the outside of the protective inner liner 7. The two ends of the tightening sleeve 39 are respectively coaxially fixedly connected to the two tightening gear rings 29. The tightening gear ring 29 located at the top is coaxially fixedly connected to the transfer gear ring 28. The rotation of the two tightening gear rings 29 can drive a number of tightening mechanisms 30 to start. When the traction rack 15 moves, the traction rack 15 will drive the transfer gear 27 to rotate through the main gear 26. After the transfer gear 27 rotates, it will drive the tensioning gear ring 29 located above to rotate through the transfer gear ring 28. After the tensioning gear ring 29 located above rotates, it will drive the tensioning gear ring 29 located below to rotate through the tensioning sleeve 39.

[0051] In order to supplement the specific structure of the tightening mechanism 30, the following features are also specifically provided:

[0052] The tightening mechanism 30 also includes two tightening gears 31, two T-shaped slide bars 32, two limit bolts 34 and two positioning blocks 35. The two tightening gears 31 are respectively arranged on the sides of the two tightening gear rings 29 and are rotatably connected to the ends of the waterproof shell 10. The two limit bolts 34 are respectively fixedly connected to the sides of the two tightening gears 31 away from the tightening sleeve 39. The two positioning blocks 35 are respectively fixedly connected to the two ends of the waterproof shell 10. The two T-shaped slide bars 32 are respectively slidably connected to the two positioning blocks 35. A strip-shaped through hole 33 is formed on the side of the T-shaped slide bar 32 close to the tightening sleeve 39. The limit bolts 34 are slidably connected to the strip through hole 33. The movement of the T-shaped slide bar 32 can drive the corresponding tightening wheel 38 to move. After the tensioning gear ring 29 rotates, the tensioning gear ring 29 will drive the limiting bolt 34 to move through the tensioning gear 31. When the limiting bolt 34 moves, it will drive the T-shaped slide bar 32 to move through the strip through hole 33. After the T-shaped slide bar 32 moves, it can drive the clamping wheel 38 to press against the inner wall of the observation tube 5 to prevent the measuring end 3 from shifting when moving along the inner wall of the observation tube 5.

[0053] In order to realize that the pressing wheel 38 is elastically pressed against the inner wall of the observation tube 5, the following features are also specifically provided:

[0054] The tightening mechanism 30 further includes a sliding bracket 36 and a tightening spring 37. One end of the sliding bracket 36 is slidably connected to the T-shaped sliding rod 32, and the other end is rotatably connected to the tightening wheel 38. The tightening spring 37 is sleeved on the outside of the sliding bracket 36. One end of the tightening spring 37 is fixedly connected to the sliding bracket 36, and the other end is fixedly connected to the positioning block 35 (refer to Figure 8 ). When the T-shaped slide bar 32 moves, the T-shaped slide rail will drive the pressing wheel 38 to press against the inner wall of the observation tube 5 through the sliding bracket 36. At this time, the pressing spring 37 will be compressed to ensure that the pressing wheel 38 and the observation tube 5 are elastically pressed against each other. It can be seen that the tension of the traction spring 17 should be greater than the elastic force of the pressing springs 37 to avoid the failure of the pressing springs 37 to complete the compression.

[0055] The working principle of this device is that the operator places the measuring device body 1 on the upper end of the observation tube 5, and then the operator starts the measuring device body 1 to let the measuring end 3 fall along the observation tube 5. During this process, a number of clamping wheels 38 will be pressed against the inner wall of the waterproof shell 10. At this time, the measuring end 3 can move along the observation tube 5 without deflection, thereby ensuring the accuracy of the measurement result. As the measuring end 3 moves downward, until the water body passes through the interception cover 43 and enters the water pumping tube 41, the water body contacts the measuring end 3 in the water pumping tube 41, and the measuring end 3 feeds back the signal to the controller in the measuring device body 1. After the controller is electrically connected to the Internet of Things, it can record this data, thereby realizing the collection of water level measurement data.

[0056] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
