[0029] The present invention will be described in detail below with reference to the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] An embodiment of the present invention discloses an intelligent measuring liquid level meter, including a control body 1, a liquid level meter body 5 and a power connection line 10. The power connection line 10 is installed between the liquid level meter body 5 and the control body 1. The power connection line 10 can provide power to the liquid level meter body 5. The length of the power connection line 10 is also the depth to which the liquid level meter body 5 can sink. The liquid level meter body 5 can detect the water level. After the liquid level meter body 5 is extended underwater, the liquid level meter body 5 can detect the depth of the water after entering the water.

[0031] Ginseng Figure 1~Figure 2 As shown, a display platform 2 is provided on the control body 1, and the display platform 2 is used to display the detection data detected by the liquid level meter body 5. The data detected by the liquid level meter body 5 can be transmitted to the control body 1 through the power connection line 10. The control body 1 is also provided with an Internet of Things module. The Internet of Things module can store the data transmitted by the liquid level meter body 5 in the cloud, which is convenient for storing the data. The intelligent measuring liquid level meter also includes mobile phone control software. The data stored in the cloud can be queried through the mobile phone control software, and the data detected by the liquid level meter body 5 can also be remotely observed in real time through the mobile phone control software.

[0032] Specifically, the display platform 2 is provided with a first display screen 201 and a second display screen 202. The first display screen 201 is used to observe the video data transmitted from the liquid level meter body 5, and the second display screen 202 is used to observe the water level data transmitted from the liquid level meter body 5. Both the video data and the water level data can be stored through the Internet of Things module and can be queried through the collection control software.

[0033] Ginseng Figure 1~Figure 2 As shown, the liquid level meter body 5 includes a first connecting part 6 and a liquid level meter detection body 7. The first connecting part 6 and the liquid level meter detection body 7 are snap-connected, and there is a certain degree of sealing between the first connecting part 6 and the liquid level meter detection body 7. When the liquid level meter body 5 enters the water, it is not easy for water to enter the first connecting part 6 from between the first connecting part 6 and the liquid level meter detection body 7. The first connecting part 6 is a hollow cover shape, and the liquid level meter detection body 7 is inserted into the first connecting part 6.

[0034] Specifically, Figure 1~Figure 2 Combine Figure 8 As shown, one end of the power connection line 10 is installed on the first connection part 6, and a first contact 602 is provided inside the first connection part 6. A second contact 705 matching the first contact 602 is provided on the liquid level meter detection body 7. The liquid level meter detection body 7 transmits electrical energy through the second contact 705 and the first contact 602, that is, the liquid level meter detection body 7 and the first connection part 6 power the liquid level meter detection body 7 through contacts. The first connection part 6 and the liquid level meter detection body 7 are snap-connected and powered by contacts. When the liquid level meter detection body 7 is damaged, the liquid level meter detection body 7 can be easily replaced, which can greatly reduce the time consumed in replacing the liquid level meter detection body 7 after the liquid level meter detection body 7 is damaged, and greatly improves the convenience of replacing the intelligent measuring liquid level meter. If the current liquid level meter detection body 7 cannot meet the detection requirements, the model of the liquid level meter detection body 7 can also be quickly replaced, which is convenient for improving the use scenarios of the intelligent measuring liquid level meter. Different models of liquid level meter detection bodies 7 can be replaced according to different environments to make the detection results more accurate.

[0035] Ginseng Figure 2 As shown, a plurality of first threaded holes 601 are provided on the first connecting portion 6, and a second threaded hole 701 matching the first threaded hole 601 is provided on the liquid level meter detection body 7. The first threaded hole 601 and the second threaded hole 701 are sequentially plugged with connectors 11. The top of the connector 11 is fixedly connected with a magnetic block. The magnetic block and the liquid level meter detection body 7 are magnetically connected. The magnetic block can be adsorbed with the liquid level meter detection body 7 and can fix the liquid level meter detection body 7. The connector 11 can prevent the liquid level meter detection body 7 from being easily detached from the first connecting portion 6.

[0036] Specifically, Figure 6 As shown, a first sealing sleeve 12 is installed between the first connecting part 6 and the liquid level instrument detection body 7. A through hole 1201 matching the first threaded hole 601 is opened on the first sealing sleeve 12. The first sealing sleeve 12 is sleeved on the upper end of the liquid level instrument detection body 7 and then inserted into the first connecting part 6. The first sealing sleeve 12 can reduce the gap between the first connecting part 6 and the liquid level instrument detection body 7, and avoid water from entering the first connecting part 6 through the gap between the first connecting part 6 and the liquid level instrument detection body 7 as much as possible, thereby causing electric shock to the first contact 602 and the second contact 705.

[0037] Ginseng Figure 2~Figure 3 As shown, a second connecting part 15 is installed between the first connecting part 6 and the liquid level meter detection body 7. The second connecting part 15 includes a connecting ring 1501, a first connecting rope 1502, a second connecting rope 1503 and a third connecting rope 1504. The inner diameter of the connecting ring 1501 matches the outer diameter of the plug-in connector 11. The connecting ring 1501 can be sleeved on the inside of the plug-in connector 11. The connecting ring 1501 is first sleeved on the plug-in connector 11, and the plug-in connector 11 is inserted into 601, 1201 and the second threaded hole 701 in sequence. The connecting ring 1501 is a magnetic block. The connecting ring 1501 is located between the upper end face of the first connecting part 6 and the plug-in connector 11. The connecting ring 1501 can make the plug-in connector 11 adsorbed with the upper end face of the first connecting part 6, so that the plug-in connector 11 is not easily separated from the first connecting part 6.

[0038] Specifically, the number of the connecting rings 1501 is three, the connecting rings 1501 and the first connecting rope 1502 are fixedly connected, each connecting ring 1501 is fixedly connected to a first connecting rope 1502, the second connecting rope 1503 is located between the first connecting rope 1502 and the third connecting rope 1504, and the number of the third connecting rope 1504 is also three. Figure 7 As shown, a connecting block 20 is fixedly connected to the liquid level meter detection body 7, and the connecting block 20 is provided with the same number of connecting holes as the third connecting rope 1504. The end of the third connecting rope 1504 away from the first connecting rope 1502 is tied in the connecting hole, that is, the second connecting part 15 is installed between the connecting block 20 and the first connecting part 6. The second connecting part 15 can further fix the first connecting part 6 and the liquid level meter detection body 7, and avoid the first connecting part 6 and the liquid level meter detection body 7 from being separated as much as possible, resulting in the liquid level meter detection body 7 being unable to be retracted, causing unnecessary economic losses, and at the same time, it can also avoid the loss of data due to failure to transmit back in time.

[0039] Preferably, a data storage module can also be provided in the liquid level meter detection body 7. The data storage module can quickly store the data detected by the liquid level meter body 5. If the liquid level meter body 5 is damaged, the data may not be transmitted to the cloud through the Internet of Things module in its entirety at the first time, which may result in data loss. The storage module can largely avoid data loss. The storage module includes a memory card. The data detected by the liquid level meter body 5 can be stored in the memory card at the first time, and then transmitted to the cloud through the Internet of Things module. If the data transmitted through the Internet of Things is incomplete, the data can be read in the memory card, and then the data can be compared to make the lost data incomplete. This can largely avoid the situation where data loss is caused by damage to the liquid level meter body 5, and the situation where data loss requires re-measurement can be avoided as much as possible.

[0040] A step further, Figure 3 As shown, the second connecting part 15 is a nylon rope, which has strong toughness and is not easy to break. At the same time, it is light in weight, and the second connecting part 15 is easy to roll together for easy carrying. The first connecting rope 1502, the second connecting rope 1503 and the third connecting rope 1504 are integrally formed. A rope storage part 16 is installed on the second connecting rope 1503. The rope storage part 16 can be a small automatic telescopic hose reel for storing the second connecting rope 1503. When the first connecting part 6 and the liquid level meter detection body 7 are separated, since there is no lower end of the liquid level meter detection body 7, the second connecting part 1502 and the second connecting rope 1503 are easily rolled together. No support, after the first connecting part 6 is separated from the liquid level meter detection body 7, the liquid level meter detection body 7 will move downward due to gravity. At this time, the second connecting rope 1503 can be extended from the rope storage part 16. As the depth of the liquid level meter detection body 7 descends, the length of the second connecting rope 1503 is longer. Generally, the length of the second connecting rope 1503 is 20 meters. The length of the second connecting rope 1503 can be changed by replacing different types of second connecting parts 15. Specifically, different types of second connecting parts 15 can be used according to actual conditions.

[0041] Among them, the first connecting part 6 has a built-in radio output module, and the liquid level meter detection body 7 is installed with a radio receiving module. The first connecting part 6 can power the liquid level meter detection body 7 through a wireless mode at a certain distance, that is, the first connecting part 6 can also power the liquid level meter detection body 7 through a wireless module. When the first connecting part 6 and the liquid level meter detection body 7 are separated, the liquid level meter detection body 7 transmits detection data to the first connecting part 6 through a pulse signal. It can also be set on the control body 1 not to use pulse signals for data transmission, and directly store the data in the memory card. After the detection is completed, the memory card is taken out and the data is read.

[0042] Preferably, a plurality of movable sealing structures can be further provided in the first connection part 6, and the sealing structure divides the first connection part 6 into a plurality of enclosed spaces. When the liquid level meter detection body 7 is inserted into the first connection part 6, the gap between the liquid level meter detection body 7 and the first connection part 6 can be filled to a certain extent. When the liquid level meter detection body 7 is detached from the first connection part 6, the second contact 705 detaches from the first sealed space, and the second contact 705 enters the second sealed space. At this time, no water will enter the first sealed space. When the second contact 705 detaches from the second sealed space, there is less water in the second sealed space. The second sealed space is located at the end of the first connection part 6 away from the first contact 602, that is, the water in the second sealed space is not easy to enter the first sealed space. The first sealed space can be kept dry, that is, the first contact 602 can be kept dry, and the situation that the first contact 602 encounters water due to the detachment of the first connection part 6 and the liquid level meter detection body 7, and the electricity of the first contact 602 is conductive when it comes into contact with water, causing damage to the first connection part 6 and the liquid level meter detection body 7.

[0043] Ginseng Figure 5 As shown, a measuring probe 22 and a micro camera 23 are installed at the lower end of the liquid level meter detection body 7. The measuring probe 22 can measure parameters such as the water level. The micro camera 23 is a 360° camera. The situation near the liquid level meter detection body 7 can be observed through the micro camera 23.

[0044] Ginseng Figure 4 As shown, a protective structure is installed on the liquid level meter detection body 7, and the protective mechanism includes a second airbag 14. A second placement groove 704 is opened at the lower end of the liquid level meter detection body 7, and the second airbag 14 is installed inside the second placement groove 704. The video data detected by the micro camera 23 is transmitted through the Internet of Things, and the video can be analyzed by the computing module. When the micro camera 23 detects that there is danger approaching, such as hitting a stone, a school of fish passing nearby, etc., the second airbag 14 will explode from the lower end of the liquid level meter detection body 7, and wrap the lower part of the liquid level meter detection body 7 to protect the liquid level meter detection body 7. Since a plurality of electronic components are provided at the lower end of the liquid level meter detection body 7, as long as the lower end of the liquid level meter detection body 7 is not seriously damaged, the liquid level meter detection body 7 can be used normally.

[0045] Ginseng Figure 4As shown, the liquid level meter detection body 7 is provided with a first placement groove 703 at the upper end near the protective structure, and the first placement groove 703 is covered with a sealing cover 9, which can completely cover the first placement groove 703, and the gap at the connection between the sealing cover 9 and the first placement groove 703 has a good seal. Even if the liquid level meter detection body 7 is in water, it is not easy for water to enter the first placement groove 703 through the gap at the connection between the sealing cover 9 and the first placement groove 703. A first airbag 13 is installed inside the first placement groove 703. When the liquid level meter detection body 7 and the first connecting part 6 are separated, and the second connecting part 15 is also separated from the liquid level meter detection body 7, the first airbag 13 can be controlled to explode by controlling the body 1, and the first airbag 13 can completely When the first placement slot 703 is filled and exploded, the sealing cover 9 can be popped out, so that the sealing cover 9 is separated from the liquid level meter detection body 7, reducing the overall weight of the liquid level meter detection body 7. At the same time, the first airbag 13 is similar to a balloon, and its volume after explosion is larger than the volume of the liquid level meter detection body 7. The liquid level meter detection body 7 can float because of the first airbag 13, which can largely avoid the liquid level meter detection body 7 from continuing to sink due to gravity, resulting in the loss of data in the memory card. The liquid level meter detection body 7 can continue to float up until it surfaces with the help of the first airbag 13. After the liquid level meter detection body 7 surfaces, the memory card is taken out and the data in the memory card can be read. During the reading process, the mobile phone software can also be used to synchronize with the database data.

[0046] Ginseng Figure 4 As shown, a water storage tank 702 is provided at the upper end of the liquid level meter detection body 7 near the first placement slot 703, that is, a water storage tank 702 is provided on the liquid level meter detection body 7, and the water storage tank 702 is located at the upper end of the first placement slot 703. A pair of second threaded holes 701 are provided on the liquid level meter detection body 7, and the pair of second threaded holes 701 are both located on the side wall of the water storage tank 702. The second threaded holes 701 can connect the outside with the inside of the water storage tank 702. A solenoid valve 8 is installed in the second threaded hole 701. The solenoid valve 8 is a micro solenoid valve. The specific model of the solenoid valve 8 can be SY3120. The solenoid valve 8 is installed in the second threaded hole 7 01 is located on the outside of the liquid level meter detection body 7, close to the outer wall of the solenoid valve 8, which can prevent water from entering the water tank 702 through the second threaded hole 701. The water tank 702 is a water storage tank. The more water there is inside the water tank 702, the heavier the overall weight of the liquid level meter detection body 7. If the weight of the liquid level meter detection body 7 is not enough to sink quickly, adding water to the water tank 702 can increase the weight of the liquid level meter detection body 7, making it easier for the liquid level meter detection body 7 to sink quickly. When the water tank 702 does not need to continue to sink quickly, the water in the water tank 702 can be drained to reduce the weight of the liquid level meter detection body 7.

[0047] Specifically, Figure 5As shown, a water pump 21 is fixedly connected to the water tank 702. The specific model of the water pump 21 is a Kammer peristaltic pump KEF. The water pump 21 can drain the accumulated water in the water tank 702 out of the water tank 702, greatly reducing the overall weight of the liquid level meter detection body 7, and reducing the situation where the liquid level meter detection body 7 quickly drops underwater due to being too heavy.

[0048] Ginseng Figure 8 As shown, a plurality of micro jet pumps 17 are also fixedly connected to the first connecting portion 6. Since the first connecting portion 6 and the liquid level meter detection body 7 are magnetically connected and sealed, when the micro jet pump 17 blows air upward toward the liquid level meter detection body 7, when there is enough gas between the first connecting portion 6 and the liquid level meter detection body 7, the connector 11 will be separated from the liquid level meter detection body 7, that is, the first connecting portion 6 will be separated from the liquid level meter detection body 7, and the liquid level meter detection body 7 can be fixed by the second connecting portion 15, so that the liquid level meter detection body 7 moves downward by gravity. The gravity of the liquid level meter detection body 7 can drive the second connecting rope 1503 to be pulled out from the rope storage part 16. If the liquid level meter detection body 7 stays at a certain position and the weight of the liquid level meter detection body 7 cannot pull the second connecting rope 1503 out of the rope storage part 16, the control body 1 can control the liquid level meter detection body 7 to open the solenoid valve 8, so that water is stored in the water tank 702, thereby increasing the weight of the liquid level meter detection body 7, so that the second connecting rope 1503 can be pulled out from the rope storage part 16, and then the liquid level meter detection body 7 can continue to sink, so that the liquid level meter detection body 7 can detect deeper underwater.

[0049] Preferably, a power supply can be built into the liquid level meter detection body 7, and the power supply can store a certain amount of electricity. When the liquid level meter detection body 7 is too deep underwater, it may affect the performance of wireless transmission, causing the first connection part 6 to be unable to supply power to the liquid level meter detection body 7. At this time, the backup power supply can be started to continue underwater detection. After the detection is completed, the liquid level meter detection body 7 can be directly pulled out of the water through the power connection line 10.

[0050] Ginseng Figure 7As described, a third sealing sleeve 19 is sleeved on the outer side of the liquid level meter detection body 7, and a second sealing sleeve 18 is sleeved between the first connecting part 6 and the liquid level meter detection body 7. The third sealing sleeve 19 and the second sealing sleeve 18 are both sealing sleeves made of rubber material, which can further enhance the waterproof effect of the liquid level meter body 5. A plurality of through holes are opened on the connecting block 20 to facilitate the leakage of the connecting block 20, the solenoid valve 8, and the sealing cover 9, thereby avoiding the situation where the electronic components and structures in the liquid level meter body 5 cannot be used normally due to the third sealing sleeve 19. At the same time, the sealing cover 9 can also increase the weight of the liquid level meter body 5. When the second connecting part 15 is used to connect the liquid level meter body 5, the sinking speed of the liquid level meter detection body 7 can be increased, thereby avoiding the situation where the liquid level meter detection body 7 cannot sink due to the light weight of the liquid level meter detection body 7.

[0051] Ginseng Figure 1~Figure 2 As shown, the display platform 2 is provided with a second control button 3 and a third control button 4. The display platform 2 is also provided with a first control button 203. Specifically, the first control button 203 can control the observation angle of the micro camera 23, and the solenoid valve 8 can be opened or closed through the third control button 4. The third control button 4 can also turn on the water pump 21, that is, the solenoid valve 8 can be controlled to fill or drain water in the water tank 702 through the third control button 4. The second control button 3 can control whether the first airbag 13 and the second airbag 14 are exploded. Pressing once will explode the first airbag 13, and clicking twice quickly will explode the second airbag 14. Whether the operation is weighing can also be observed on the first display screen 201. After pressing the button, there may be a delay or invalidity due to unstable signal transmission. It can be observed through the first display screen 201. If there is a delay or invalidity, you can click multiple times to facilitate the liquid level meter detection body 7 to receive the signal.

[0052] In the initial state, Figure 1 As shown, the power connection line 10 is installed between the liquid level meter body 5 and the control body 1, the first connecting part 6 and the liquid level meter detection body 7 are connected through the connector 11, and the solenoid valve 8, the first airbag 13, and the second airbag 14 are all installed on the liquid level meter detection body 7.

[0053] When in use, first directly throw the liquid level meter body 5 into the water, and then power on, so that the liquid level meter body 5 can detect the water. When it is necessary to detect deeper underwater, the liquid level meter body 5 can be lowered deeper underwater by continuously lowering the power connection line 10. During the descent of the liquid level meter body 5, the water will be detected, and the data will be stored and transmitted to the cloud. When the length of the power connection line 10 is not enough, the micro jet pump 17 is started to disconnect the first connecting part 6 of the liquid level meter detection body 7. The gas ejected by the micro jet pump 17 is sufficient to eject the liquid level meter detection body 7. At this time, the first connecting part 6 and the liquid The connecting rope between the level meter detection body 7 is the second connecting part 15, and the number of the third connecting ropes 1504 is three. If one of the third connecting ropes 1504 is detached from the level meter detection body 7, the other third connecting ropes 1504 can play a fixing role. The level meter detection body 7 will continue to drop due to gravity. When the micro camera 23 detects danger, the second airbag 14 will explode to protect the important electronic components in the lower half of the level meter detection body 7. The second airbag 14 can completely wrap the lower half of the level meter detection body 7, but the measuring probe 22 will still leak out, so that water can be measured normally.

[0054] If the mass of the liquid level meter detection body 7 is not enough and cannot continue to sink, the solenoid valve 8 is controlled by the third control button 4 to open the solenoid valve 8. Water enters the water storage tank 702 from the solenoid valve 8 through the second threaded hole 701. The water can increase the weight of the liquid level meter detection body 7. After the weight of the liquid level meter detection body 7 increases, it will continue to sink and detect deeper water.

[0055] If the second connecting part 15 is separated from the liquid level meter detection body 7, the first airbag 13 is controlled to explode by the second control button 3, and the water pump 21 is controlled by the third control button 4 to drain the water inside the water storage tank 702, thereby reducing the overall mass of the liquid level meter detection body 7. At the same time, the first airbag 13 is affected by the buoyancy and will drive the liquid level meter detection body 7 to float up. Finally, the liquid level meter detection body 7 floats to the surface, and then the memory card in the liquid level meter detection body 7 can be read.

[0056] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0057] The present invention enables the intelligent liquid level measuring instrument to be used in relatively deep water, can provide the intelligent liquid level measuring instrument with a longer stroke, and is not easily damaged even when the intelligent liquid level measuring instrument is used in water with relatively high pressure.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0059] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
