Description

Technical Field

[0001] The invention relates to the technical field of artesian well monitoring, and in particular to an artesian well flow and water level automatic monitoring device. Background Art

[0002] An artesian well is a well that can flow groundwater on its own. When groundwater is subjected to sufficient pressure in the underground aquifer, the water will rise along the wellbore and gush out from the wellhead, and no artificial pumping equipment is needed to lift the water. In order to reasonably allocate water resources, flow monitoring equipment and water level monitoring equipment are required to monitor the flow and water level of the artesian well. Capacitive level meters and rotor flow meters are required for monitoring. Specifically, the capacitive level meter is installed above the wellhead of the artesian well and the electrode of the capacitive level meter is inserted into the artesian well. The metal rod of the capacitive level meter serves as one pole of the capacitor, and the metal wall of the artesian well serves as the electrode of the capacitor. It is the other pole of the capacitor, and the medium between the two electrodes is well water. When the liquid level rises, the total dielectric constant value between the two electrodes increases accordingly, and thus the capacitance increases. Conversely, when the liquid level drops, the capacitance decreases. The water level is detected by the change in capacitance. When the flow of an artesian well is monitored using a rotor flowmeter, the rotor flowmeter is installed in the artesian well to monitor the speed of the rotor on the rotor flowmeter. The flow of the artesian well can then be calculated, and the monitored values ​​can be wirelessly transmitted to the monitoring system to achieve automatic monitoring of the flow and water level of the artesian well, which is beneficial to the rational allocation of water resources.

[0003] When monitoring the flow and water level of an artesian well, a capacitive level meter is used to accurately monitor the water level of the artesian well, and a rotor flow meter is used to measure the flow condition of the well water in the artesian well. However, in winter, since the well water is usually at a certain depth underground, affected by the thermal insulation efficiency of the soil, its water temperature is higher than the outside air temperature. When the well water gushes upward, the higher water temperature causes part of the water in it to evaporate easily, thereby generating water vapor. During the rising process, once these water vapors come into contact with the metal rod of the capacitive level meter with a relatively low temperature, they will condense into water droplets on the surface of the metal rod. As the number of water droplets increases, a water film will eventually form on the metal rod. The presence of the water film will change the capacitance value formed by the metal rod and the surrounding environment, thereby adversely affecting the detection accuracy of the artesian well water level, resulting in deviations in the water level monitoring data, making it difficult to accurately reflect the actual water level of the artesian well. Therefore, the present application provides an automatic monitoring device for the flow and water level of an artesian well to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an automatic monitoring device for the flow and water level of an artesian well to solve the problem that in winter, because the well water is located underground and the temperature is high due to the insulation effect of the soil, the water is easily evaporated into water vapor during the upwelling process, and the water vapor will condense into water droplets and form a water film on the metal rod of the capacitive liquid level meter when it meets the low temperature.

[0009] When working, the floating plate, sealing ring and bellows are used to block the water vapor generated by the low temperature of the well water in the artesian well body, preventing the water vapor from adhering to the part of the metal rod of the capacitive liquid level meter that is exposed to the water surface.

[0010] Preferably, a plurality of arc-shaped retaining bars are commonly connected between the mounting ring and the plug, and the arc-shaped retaining bars correspond to the positions of the vertical grooves.

[0011] Preferably, a plurality of guide vertical bars are fixed on the side of the float plate, and two protrusions are provided on the side of the guide vertical bars. The side of the protrusions is slidably connected to the side of the arc-shaped baffle bar away from the vertical groove. The protrusion close to the plug is located below the liquid surface of the artesian well body, and the protrusion away from the plug is located above the liquid surface of the artesian well body.

[0012] Preferably, a raised portion is provided on one side of the protruding portion close to the vertical groove, and a recessed portion is provided on the arc-shaped baffle bar corresponding to the raised portion, and the raised portion is slidably connected to the recessed portion.

[0013] Preferably, side plates are fixed on opposite sides of the guide vertical bars, the side plates are fixed on the sides of the floating plates, and the side plates are slidably connected to the sides of the arc-shaped baffle bars.

[0014] Preferably, the top and bottom of the protruding portion located at the bottom are respectively provided with a guide surface 1 and a guide surface 2, and a drainage outlet is provided at a location on the side surface of the side plate corresponding to the guide surface.

[0015] Preferably, a second recessed portion is provided on the side of the protective sleeve, and a third guide surface is provided on the side of the side plate away from the floating plate, the center of the third guide surface coincides with the center of the arc-shaped baffle, and the position of the third guide surface corresponds to the second recessed portion.

[0016] Preferably, a floating block is fixed on the side of the floating plate, the floating block is fixed between two adjacent side plates, and an upward curved portion is provided on a side of the floating block away from the floating plate.

[0017] Preferably, a slope is provided on the top of the inner wall of the sealing ring.

[0018] Preferably, the bottom of the plug is a curved surface that bends downward.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above scheme, through the arrangement of the floating plate, the sealing ring and the bellows, the floating plate floats on the water surface of the artesian well body and can rise and fall with the fluctuation of the water level. The sealing ring is fitted between the floating plate and the metal rod of the capacitive liquid level gauge, effectively preventing water vapor from spreading upward from the tiny gap between the two, thereby avoiding its attachment to the metal rod part above the floating plate. At the same time, the bellows seals the metal rod above the floating plate and cooperates with the sealing ring to further enhance the resistance to water vapor and ensure the accuracy of the water level detection of the artesian well body.

[0021] Through the arrangement of the protective cover and the vertical groove, when the well water in the artesian well body continues to surge, in order to effectively buffer the impact of the surged well water on the floating plate, the floating plate is installed in the protective cover, and the vertical groove on the side of the protective cover is used to connect the inside and outside of the protective cover. When the water level of the artesian well body changes, the water level in the protective cover can respond instantly and synchronously. While realizing accurate detection of the water level of the artesian well body, it greatly reduces the interference of the surged well water on the floating plate, and effectively prevents the adverse effects on the detection accuracy of the capacitive liquid level meter caused by excessive or abnormal up and down movement of the floating plate, so that the water level measurement is always stable and accurate.

[0022] Through the setting of the arc-shaped baffle, in a rainy environment, raindrops falling on the water surface of the artesian well body will cause fluctuations in the water surface, and these fluctuations will be transmitted to the protective cover through the vertical grooves. At this time, the arc-shaped baffle blocks the water surface fluctuations transmitted from the vertical grooves, effectively reducing the interference of the water surface fluctuations on the floating plate, allowing the floating plate to work in a relatively stable environment, thereby ensuring that the accuracy of the water level measurement is not affected by changes in water surface fluctuations, and allowing the measurement data to more accurately and reliably reflect the water level status of the artesian well body.

[0023] Through the setting of the guide vertical bars, when the float moves up and down with the water level changes, the guide vertical bars will slide smoothly along the sides of the arc-shaped baffles, providing guidance for the up and down movement of the float, and when the water surface fluctuates, the guide vertical bars can effectively prevent the float from swinging due to the impact of the water flow, thereby further improving the accuracy of water level measurement.

[0024] Through the setting of the second recessed part, the fluctuation of the water surface will be transmitted to the second recessed part after being initially blocked and guided by the arc-shaped baffle. The second recessed part blocks the fluctuation of the water surface again, thereby dispersing and eliminating the energy of the fluctuation, making the water surface in the protective cover tend to be stable, creating a more stable working environment for the floating plate, thereby once again effectively ensuring the accuracy of the water level measurement.

[0025] By setting the side plates, the side plates are utilized to prevent the movement of the water surface from being transmitted to between the upper and lower protrusions on the guide vertical bars. With the help of the guide surface three of the side plates, the movement of the water surface is guided to the recessed portion two for processing, thereby further reducing the influence of the water surface movement on the floating plate and more effectively ensuring the accuracy of the water level measurement.

[0043] like Figure 1-Figure 10 As shown, an embodiment of the present invention provides an automatic monitoring device for flow and water level of an artesian well, comprising an artesian well body 1, and further comprising:

[0044] A capacitive liquid level gauge 3, a mounting frame 2 is mounted on the artesian well body 1, the capacitive liquid level gauge 3 is mounted in the mounting frame 2, a metal rod of the capacitive liquid level gauge 3 is inserted into the artesian well body 1, and the capacitive liquid level gauge 3 is used to detect the water level in the artesian well body 1;

[0045] The protective mechanism 4 includes a protective sleeve 5 which is sleeved on the metal rod of the capacitive liquid level gauge 3. The protective sleeve 5 is made of nylon and is non-conductive, thereby preventing the protective sleeve 5 from affecting the detection of the capacitive liquid level gauge 3. A mounting ring 6 is fixed on the top of the protective sleeve 5. The mounting ring 6 is detachably connected to the top of the inner wall of the mounting frame 2. The mounting frame 2 is mainly composed of a lower circular ring, a bent rod and an upper plate. The lower circular ring is sleeved on the well wall of the artesian well body 1. The side of the lower circular ring is threadedly connected with bolts, and the bolts are pressed against the well wall of the artesian well body 1 to achieve the positioning and fixation of the lower circular ring. The bent rod is used for connecting the lower circular ring and the upper plate. The mounting ring 6 fits on the bottom of the flange of the capacitive liquid level gauge 3, and the flange of the capacitive liquid level gauge 3 fits on the bottom of the upper plate. The screw on the mounting ring 6 passes through the flange and the upper plate of the capacitive liquid level gauge 3 in turn, and then the nut is tightened on the screw to achieve the installation and fixation of the mounting ring 6 and the capacitive liquid level gauge 3. When disassembling, remove the nut from the screw The capacitive level gauge 3 and the mounting ring 6 can be removed in turn by unscrewing. A plurality of vertical grooves 8 are provided on the outer wall of the protective sleeve 5. A floating plate 10 is slidably sleeved on the metal rod of the capacitive level gauge 3. The floating plate 10 is located inside the protective sleeve 5, and a sealing ring 11 is inlaid on the inner wall of the floating plate 10. The inner wall of the sealing ring 11 fits the metal rod of the capacitive level gauge 3. A bellows 27 is installed on the top of the floating plate 10. The top of the bellows 27 is fixedly connected to the bottom of the flange of the capacitive level gauge 3. The metal rod of the capacitive level gauge 3 is located inside the bellows 27. A plug 7 is fixed to the bottom of the protective sleeve 5. A rotating shaft 25 is fixed to the bottom of the plug 7. A rotor 26 is rotatably connected to the bottom of the rotating shaft 25. The rotor 26 is used to detect the flow rate of water in the artesian well body 1. A speed sensor is installed at the rotating shaft 25. The speed sensor is used to detect the speed of the rotor 26. Then, the flow rate of water in the artesian well body 1 can be calculated according to the corresponding calculation method.

[0046] During operation, the floating plate 10, the sealing ring 11 and the bellows 27 cooperate to block the water vapor generated by the low temperature of the well water in the artesian well body 1, and prevent the water vapor from adhering to the part of the metal rod of the capacitive liquid level meter 3 that is exposed to the water surface.

[0047] like Figure 3-Figure 8As shown, in the present embodiment, a plurality of arc-shaped baffles 9 are connected between the mounting ring 6 and the plug 7. The arc-shaped baffles 9 correspond to the positions of the vertical grooves 8. The arc-shaped baffles 9 are made of nylon and are non-conductive, so as not to affect the detection of the capacitive liquid level gauge 3. On rainy days, the fluctuations caused by rain drops falling on the water surface of the artesian well body 1 will be transmitted to the protective cover 5 through the vertical grooves 8. The arc-shaped baffles 9 can effectively block these fluctuations and reduce their interference with the floating plate 10, so that the water surface in the protective cover 5 where the floating plate 10 is located is relatively stable, ensuring that the floating plate 10 will not produce unnecessary shaking or displacement due to water surface fluctuations, thereby ensuring that the accuracy of the water level measurement is not disturbed by changes in water surface fluctuations, and allowing the measurement data to more accurately and reliably reflect the water level status of the artesian well body 1, especially when the water surface fluctuates frequently, to maintain stable water level monitoring performance.

[0048] like Figure 8 As shown, in this embodiment, a plurality of guide vertical bars 13 are fixed to the side of the floating plate 10, and two protrusions 14 are arranged on the side of the guide vertical bar 13. The side of the protrusion 14 is slidably connected to the side of the arc-shaped retaining bar 9 away from the vertical groove 8. The protrusion 14 close to the plug 7 is located below the liquid surface of the artesian well body 1, and the protrusion 14 away from the plug 7 is located on the liquid surface of the artesian well body 1. The guide vertical bar 13 is made of nylon and is not conductive, so it will not affect the detection of the capacitive liquid level meter 3. When the floating plate 10 changes with the water level, the water level of the floating plate 10 will not be affected. When moving up and down, the guide vertical bar 13 will slide smoothly along the side of the arc-shaped baffle bar 9, providing precise guidance for the up and down movement of the floating plate 10, preventing it from shifting or tilting during the movement, and ensuring that the floating plate 10 can accurately move with the rise and fall of the water level, thereby improving the accuracy of the water level measurement. The design of the protrusion 14 on the guide vertical bar 13 can reduce the contact area between the guide vertical bar 13 and the arc-shaped baffle bar 9, thereby reducing the friction between the two and making the movement of the guide vertical bar 13 smoother.

[0049] like Figure 6 and Figure 8 As shown, in the present embodiment, a protrusion 15 is provided on one side of the protrusion 14 close to the vertical groove 8, and a recessed portion 16 is provided at the arc-shaped baffle bar 9 corresponding to the protrusion 15, and the protrusion 15 is slidably connected to the recessed portion 16, and the protrusion 15 is slidably connected to the recessed portion 16, which further enhances the connection stability between the guide vertical bar 13 and the arc-shaped baffle bar 9, so that when the floating plate 10 moves up and down with the water level, the guide vertical bar 13 can slide along the arc-shaped baffle bar 9 more tightly and stably, thereby ensuring the smoothness and continuity of the movement of the floating plate 10.

[0050] like Figure 6 , Figure 8 , Fig. 9 and Fig.10As shown, in this embodiment, side plates 18 are fixed on opposite sides of the guide vertical bar 13, the side plates 18 are fixed on the side of the floating plate 10, and the side plates 18 are slidably connected to the side of the arc-shaped baffle bar 9. The side plates 18 are fixed on the side of the floating plate 10 and slidably connected to the side of the arc-shaped baffle bar 9 to prevent water surface fluctuations from being transmitted to between the upper and lower protrusions 14 on the guide vertical bar 13.

[0051] like Fig. 9 and Fig.10 As shown, in the present embodiment, the top and bottom of the protrusion 14 located at the bottom are respectively provided with a guide surface 19 and a guide surface 20, and a drainage port 22 is opened on the side of the side plate 18 corresponding to the guide surface 19. When the floating plate 10 moves upward due to the influence of the water level, the protrusion 14 located at the bottom on the guide vertical bar 13 is driven to move upward. The design of the guide surface 19 is used to reduce the resistance of the protrusion 14 located at the bottom to move upward in the water, so that the movement of the guide vertical bar 13 is smoother. When the floating plate 10 moves downward due to the influence of the water level, the protrusion 14 located at the bottom is driven to move downward. The design of the guide surface 20 is used to reduce the resistance of the protrusion 14 located at the bottom to move downward in the water, so that the movement of the guide vertical bar 13 is smoother, so that the movement of the floating plate 10 is smoother and it can sensitively follow the change of the water level to rise and fall.

[0052] like Figure 6 and Figure 7 As shown, in the present embodiment, a recessed portion 21 is provided on the side of the protective cover 5, and a guide surface 3 21 is provided on the side of the side plate 18 away from the floating plate 10, the center of the guide surface 3 21 coincides with the center of the arc-shaped baffle 9, and the guide surface 3 21 corresponds to the position of the recessed portion 17. The guide surface 3 21 of the side plate 18 guides the water surface fluctuation to the recessed portion 17 of the protective cover 5 for dispersion and elimination, thereby making the water surface in the protective cover 5 more stable, providing a stable working environment for the floating plate 10, and effectively ensuring that the accuracy of the water level measurement is not affected by the water surface fluctuation and the impact of the water flow.

[0053] like Figure 8 As shown, in this embodiment, a float block 23 is fixed on the side of the float plate 10, the float block 23 is fixed between two adjacent side plates 18, and an upper curved portion 24 is provided on the side of the float block 23 away from the float plate 10, the float block 23 is used to increase the contact area between the float plate 10 and the water surface, and the influence of the water surface movement on the float plate 10 is further reduced through the cooperation of the float block 23 and the upper curved portion 24, thereby further ensuring the detection accuracy of the capacitive liquid level meter 3.

[0054] like Figure 4 As shown, in this embodiment, a slope 12 is provided on the top of the inner wall of the sealing ring 11, and the slope 12 is used to reduce the contact area between the sealing ring 11 and the metal rod on the capacitive liquid level gauge 3, thereby reducing the friction between the sealing ring 11 and the capacitive liquid level gauge 3, making the movement of the floating plate 10 smoother.

[0055] like Figure 3 As shown, in this embodiment, the bottom of the plug 7 is a downward curved surface, which reduces the impact on the well water flowing through the plug 7, ensures the smooth flow of the well water, reduces the impact of the plug 7 on the water flow, and thus ensures the detection accuracy of the rotor 26.

[0056] Working principle: The capacitive level meter 3 is installed in the mounting frame 2 of the artesian well body 1, and its metal rod is inserted into the well. When the water level in the artesian well body 1 changes, the capacitive level meter 3 changes the capacitance value according to the different lengths of the metal rod immersed in the water, thereby detecting the change in the water level and realizing the monitoring of the water level in the artesian well body 1;

[0057] The protective sleeve 5 is sleeved on the metal rod of the capacitive liquid level gauge 3, and the plug 7 at the bottom seals the bottom of the protective sleeve 5. The vertical groove 8 on the outer wall of the protective sleeve 5 ensures that the water level inside the protective sleeve 5 is connected with the water level inside the artesian well body 1, so that the water level in the protective sleeve 5 can change synchronously with the water level of the artesian well body 1. The floating plate 10 is slidably sleeved on the metal rod of the capacitive liquid level gauge 3, and the sealing ring 11 on its inner wall fits with the metal rod to prevent the water vapor generated by the low temperature of the well water from spreading upward from the gap between the floating plate 10 and the metal rod to the part of the electric metal rod exposed to the water surface, and cooperates with the bellows 27 to prevent the condensation of water vapor from affecting the detection accuracy of the capacitive liquid level gauge 3;

[0058] When the well water in the artesian well body 1 rises, the protective cover 5 provides a buffer space for the floating plate 10, and the vertical groove 8 enables the water level in the protective cover 5 to respond to the external water level change in time, and reduces the direct impact of the rising well water on the floating plate 10 through the protective cover 5, avoiding the floating plate 10 from abnormal up and down movement due to excessive impact, thereby stabilizing the position of the floating plate 10, so that the capacitive liquid level meter 3 can accurately detect the water level according to the position change of the floating plate 10;

[0059] The arc-shaped retaining strip 9 connected between the mounting ring 6 and the plug 7 corresponds to the position of the vertical groove 8 of the protective cover 5. On rainy days, when the fluctuations caused by rain drops falling on the water surface of the artesian well body 1 are transmitted through the vertical groove 8, the arc-shaped retaining strip 9 can block these fluctuations and reduce their interference with the floating plate 10, so that the water surface in the protective cover 5 where the floating plate 10 is located is relatively stable, ensuring that the floating plate 10 will not produce unnecessary shaking or displacement due to water surface fluctuations, thereby ensuring the accuracy of water level measurement;

[0060] The guide vertical bar 13 on the side of the floating plate 10 slides along the side of the arc-shaped baffle 9 when the floating plate 10 rises and falls with the water level, providing guidance for the up and down movement of the floating plate 10 to prevent it from being offset or tilted during the movement. The protrusion 14 on the guide vertical bar 13 is slidably connected with the recessed portion 16 of the arc-shaped baffle 9, further enhancing the stability of the guidance. At the same time, the side plate 18 is fixed to the side of the floating plate 10 and slidably connected to the side of the arc-shaped baffle 9 to prevent water surface fluctuations from being transmitted between the upper and lower protrusions 14 on the guide vertical bar 13. The guide surface 21 of the side plate 18 guides the water surface fluctuations to the recessed portion 17 of the protective cover 5 for dispersion and elimination, thereby making the water surface in the protective cover 5 more stable, providing a stable working environment for the floating plate 10, and effectively ensuring that the accuracy of water level measurement is not affected by water surface fluctuations and water flow impact.

[0061] When the floating plate 10 is affected by the water level and moves upward, the protrusion 14 located below the guide vertical bar 13 is driven to move upward, and the design of the guide surface 19 is used to reduce the resistance of the protrusion 14 located below to move upward in the water, so that the movement of the guide vertical bar 13 is smoother. When the floating plate 10 is affected by the water level and moves downward, the protrusion 14 located below is driven to move downward, and the design of the guide surface 20 is used to reduce the resistance of the protrusion 14 located below to move downward in the water, so that the movement of the guide vertical bar 13 is smoother, so that the movement of the floating plate 10 is smoother and can be sensitively raised and lowered following the change of the water level.

[0062] The rotating shaft 25 at the bottom of the plug 7 at the bottom of the protective sleeve 5 is rotatably connected to the rotor 26. When water flows in the artesian well body 1, the water impacts the rotor 26, causing it to rotate around the rotating shaft 25. The rotation speed of the rotor 26 is detected by a speed sensor installed on the rotating shaft 25, and the flow rate in the artesian well body 1 can be calculated according to the corresponding calculation method.

[0063] The present invention encompasses any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
