Description

Technical Field

[0001] The invention relates to the technical field of hydrogeological monitoring, and more particularly to a cantilever automatic monitoring system for bidirectional condensation water in soil. Background Art

[0002] Condensation water refers to the condensation of atmospheric water vapor and soil pore water vapor from vapor water into liquid water in the ground and surface soil when the ground temperature and surface ground temperature reach the dew point. This condensation water is a component of soil water. Natural conditions such as drastic day and night temperature difference and relative air humidity are important factors affecting its generation. Under arid and extremely arid conditions, such as in arid areas where water resources are extremely scarce, any supplementary water resources may have a positive impact on its ecosystem. As a stable and continuous water resource, although the amount of condensation water is small, it plays a very important role in maintaining the stability of the ecosystem in arid and semi-arid areas. Condensation water is an important source of water for some plants, insects, small animals, and biological soil crusts in arid environments. It can increase the germination rate of plant seeds and effectively reduce the water loss caused by soil evaporation. In addition, as a source of moisture, condensation water also plays an important role in maintaining the stability of sand dunes.

[0003] At present, condensation water is mainly observed manually, and condensation water is mainly formed at night and in the early morning. It is difficult to observe manually in the field at night. Even in the high-altitude uninhabited areas in the northwest, there is no food and water, no communication signal or weak signal, and protected animals and wild beasts often appear. There are no conditions for manual observation, which makes it impossible to obtain long-term and continuous field observation data, and the error is large. Even though artificial observation experiments on condensation water have been carried out in different regions, although some results have been achieved, most of the observation time is short, and only the existence of condensation water and the measurement of generation time are proved. Due to the limitations of many conditions such as observation time and observation frequency, these observations are difficult to reflect the circulation law and conservation capacity of condensation water in the monitored area, resulting in relatively slow research on the efficient utilization of condensation water.

[0004] Therefore, based on the existing manual observation of condensate water, how to provide a condensate water measuring device and a real-time monitoring system suitable for no manual operation has become a problem that technical personnel in this field need to solve urgently.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See attached Figures 1 to 4 The embodiment of the present invention discloses a cantilever automatic monitoring system for two-way condensation water in soil, which can be installed on the ground 1, and includes:

[0042] Test tube 2, which is filled with in-situ soil and can be buried near the surface to measure the amount of water vapor condensation in the near-surface air and the soil below the surface;

[0043] A lifting mechanism 3, wherein the fixing portion of the lifting mechanism 3 can be vertically fixed on the ground 1;

[0044] The weighing mechanism 4 includes a cantilever platform 41 and a balance 43. One end surface of the cantilever platform 41 is connected to the lifting part of the lifting mechanism 3 to form a cantilever lifting structure. A through hole 411 is provided in the middle of the cantilever platform 41. The balance 43 is clamped on the top surface of the cantilever platform 41. A hook 44 is fixed on the bottom surface of the balance 43. The hook 44 passes through the through hole 411 and hangs the test tube 2 to weigh it.

[0045] The intelligent control mechanism 5 is fixed on the ground 1 and electrically connected to the driving motor of the lifting mechanism 3 and the balance 43. The intelligent control mechanism 5 is communicatively connected to the remote terminal to realize data collection and remote communication.

[0046] like Figure 5 and 6 As shown, the test tube 2 includes an outer tube 21 and an inner tube 22 with both ends being connected. The inner tube 22 is coaxially arranged in the inner cavity of the outer tube 21, and there is a gap between the outer wall of the inner tube 22 and the inner wall of the outer tube 21; the bottom end of the outer tube 21 is sealed by a first plastic film 211, and a circular hole arranged concentrically with the inner tube 22 is opened in the middle of the first plastic film 211, and the circular hole is covered by a first fine-mesh net 212; the bottom end of the inner tube 22 is sealed by a second fine-mesh net 221; wherein, the inner tube 22 contains the in-situ soil, and the hook 44 hangs the inner tube 22.

[0047] In actual use, the outer tube is buried in the ground, the inner tube is located in the inner cavity of the outer tube, the inner tube contains the in-situ soil, the top surface of the inner tube is flush with the ground surface, and the top surface of the outer tube is higher than the ground surface. This arrangement can prevent the influence of external wind, soil and particulate matter on the inner tube by utilizing the barrier of the outer tube.

[0048] The outer cylinder adopts a bottomless and coverless plexiglass column with a wall thickness of 3mm and a diameter of 30cm. The height is designed according to the on-site installation requirements, and is generally controlled at 30-50cm. The inner cylinder is sealed with a second nylon mesh, which is a bottom-through inner cylinder. The specifications adopt a bottomless and coverless plexiglass column with a wall thickness of 3mm and a diameter of 10cm. The height is designed according to the monitoring requirements, and generally 5cm, 10cm, 20cm height can be selected. The first dense mesh can be a 200-mesh nylon screen, and the second dense mesh can be a 400-mesh nylon screen. When making, the aperture of the circular hole opened in the plastic film at the bottom of the outer cylinder can be slightly larger than the outer diameter of the outer cylinder. The first dense mesh is used as a water vapor permeable hole to ensure that the water vapor inside the in-situ soil can be connected with the lower soil and the near-ground air at the same time under the premise that the quality of the in-situ soil inside the inner cylinder remains unchanged, and the water vapor condensation in the near-ground air and the lower soil can be measured at the same time.

[0049] In some other specific embodiments, Figure 7As shown, the inner cylinder 22 can be sealed with a second plastic film 222. The second plastic film can ensure that the quality of the in-situ soil inside the inner cylinder remains unchanged, and there is no exchange of water vapor inside the in-situ soil with the underlying soil. Only the upper surface of the inner cylinder is connected to the near-ground air, and only the amount of water vapor condensation in the near-ground air is measured.

[0050] The combination of different forms of inner and outer tubes greatly improves the contact between the test tube and the soil, creatively solves the problem of the inability to accurately measure the condensation water in the soil, and greatly improves the reliability and availability of the data.

[0051] In this embodiment, the range of the balance 43 is 5 kg and the accuracy is 0.01 g. The use of desserts increases the measurement accuracy to 0.01 g and the test tube weighing range to 5 kg, greatly improving the accuracy and practicality of the monitoring system.

[0052] In order to further optimize the above technical solution, the intelligent control mechanism 5 includes a pole 51, an intelligent control box 52, a battery 53, a photovoltaic panel 54 and a monitoring camera 55. The pole 51 is vertically fixed on the ground 1, and the intelligent control box 52 is fixed on one side of the pole 51; the battery 53 is buried in the ground 1 and electrically connected to the intelligent control box 52; the photovoltaic panel 54 is fixed on the top surface of the pole 51 and electrically connected to the battery 53 to charge it; the monitoring camera 55 is fixed on the side of the pole 51 facing the test tube 2 to monitor the test tube 2 and the balance 43.

[0053] like Figure 2 and 4 As shown, the intelligent control box is equipped with low-consumption terminals, air switches, relays, boost modules, buck modules, wiring terminals, 4G / Beidou communication antennas, etc. The battery power line, photovoltaic panel power line, lifting motor lifting controller power line and communication line, monitoring camera power line and communication line, and 4G / Beidou communication antennas are all connected to the wiring terminals one by one. The 4G / Beidou signal antenna is fixed on the top of the intelligent control box and connected to the measurement and control acquisition terminal for remote communication.

[0054] The battery is a 120AH gel battery, installed in an underground box, wrapped with thermal insulation cotton on the outside, and then wrapped with sealed plastic, and buried next to the pole; the photovoltaic panel is a 100W fast-charging solar panel; the pole is an iron pipe with a diameter of 110cm, with a lightning rod installed on the top, about 2m high, and there are openings on the upper and lower sides to accommodate the passage of communication lines and power lines.

[0055] The vertical pole 51 is fixed to the vertical pole foundation 56 by expansion bolts. The vertical pole foundation 56 is buried in the soil. An inclined support frame is provided at the bottom of the vertical pole 51 to ensure the stability of the vertical pole 51.

[0056] In order to further optimize the above technical solution, the lifting mechanism 3 includes a fixed frame 31, a lifting motor 33, a ball screw 34 and a lifting block 35. The fixed frame 31 can be vertically fixed on the ground 1, and the lifting motor 33 is fixed on the top surface of the fixed frame 31; the ball screw 34 is rotatably connected to one side of the fixed frame 31 and one end of the ball screw 34 is transmission connected to the lifting motor 33; a threaded hole is provided on the lifting block 35 and is threadedly connected to the ball screw 34; one end of the cantilever platform 41 is bolted to the end face of the lifting block 35 away from the ball screw 34.

[0057] like Figure 3 As shown, a vertical plate 42 is vertically fixed to one end of the top surface of the cantilever platform 41 , and the vertical plate 42 and the cantilever platform 41 form an L-shaped structure. A threaded hole is opened on the vertical plate 42 and is bolted to one side end of the lifting block 35 .

[0058] The lifting mechanism uses a ball screw to convert rotational motion into linear motion of the nut. The ball screw is a commonly used mechanical transmission structure and will not be described in detail here. The cantilever platform and the vertical plate are arranged vertically to form an L shape. The top surface of the cantilever platform is covered with a 3mm thick galvanized plate. A 7cm round hole is opened in the center of the galvanized plate to facilitate the penetration of the hook. An assembly hole is opened in the middle of the lifting block and fixed to the nut on the ball screw. A limit plate is fixed on the top or bottom surface of the lifting block to limit the displacement of the lifting block sliding up and down.

[0059] In order to further optimize the above technical solution, two support plates arranged at intervals are vertically fixed to the side wall of the fixed frame 31, and the ball screw 34 is rotatably connected between the two opposite panels of the two support plates, and the lifting motor 33 is fixed on the top surface of the support plate located on the upper layer. The lifting motor is electrically connected to the lifting controller in the intelligent control box to control the forward or reverse rotation of the lifting motor, thereby realizing the lifting block driving the cantilever platform to move up and down along the ball screw. Through the movement of the lifting block, the inner cylinder can be better cleaned, or the in-situ soil can be refilled in the inner cylinder.

[0060] In order to further optimize the above technical solution, a slide rail 32 is further included. The slide rail 32 is fixed to a side wall of the fixing frame 31 and is located between two supporting plates. One side end of the lifting block 35 is slidably connected to the slide rail 32 .

[0061] like Figure 4 As shown, the two ends of the slide rail are bolted with an origin limiter and an end limiter, and the limit installation position can be controlled by tightening the screws. The origin limiter and the end limiter are communicatively connected to the lifting controller to further limit the displacement of the lifting block sliding up and down.

[0062] In order to further optimize the above technical solution, it also includes a balance protection cover 6; the top surface of the cantilever platform 41 is fixed with four angle steels 7 arranged in an inner and outer double layer, wherein the four angle steels 7 arranged in the inner layer are clamped with the four corners of the balance 43, and the balance protection cover 6 is clamped between the four angle steels 7 in the inner and outer layers.

[0063] like Figure 1 As shown in the figure, the balance protection cover is a uncovered plexiglass cuboid slightly larger in length, width and height than the balance. It is made of highly transparent material and 3mm thick. The balance protection cover is buckled on the cantilever platform, and the edge is stuck in the middle of the two layers of angle steel on the cantilever platform to ensure that the balance protection cover does not slide inside and outside. The side wall of the balance protection cover has holes to allow communication lines and power lines to pass through. At the same time, the gap is sealed with butyl waterproof tape to ensure waterproof effect.

[0064] In order to further optimize the above technical solution, a fixing frame protection cover 8 is further included. The fixing frame protection cover 8 is buckled with the fixing frame 31. A sliding groove is opened on the side of the fixing frame protection cover 8 facing the cantilever platform 41, and the lifting block 35 can slide up and down along the sliding groove.

[0065] The fixing frame 31 is welded by square tubes and angle irons. The fixing frame 31 is fixed to the ground through a fixing frame foundation 36. The fixing frame foundation 36 is buried in the soil. The fixing frame protective cover 8 can prevent the fixing frame 31 from being eroded by rainwater, thereby ensuring the continuity and stability of the operation of the lifting mechanism 3.

[0066] The present invention is mainly used for automatically collecting and transmitting the changes in soil condensation water quality. The system converts the rotation operation into linear operation through a ball screw and then controls the lifting and lowering of a high-precision balance. The balance is a bottom-weighing balance, and the bottom-through inner cylinder or the bottom-sealed inner cylinder is weighed regularly through a hook; the test cylinder is an independently designed inner and outer combined sleeve, and the specifications and dimensions can be set according to requirements.

[0067] The intelligent control box is integrated with a real-time acquisition and transmission system, which can remotely collect, transmit, store, view and download data, and can remotely control the weighing frequency and the weighing start and stop process; the system has its own battery and photovoltaic panel, which can be charged in real time; the system has its own remote monitoring camera and early warning program, which can issue early warning reminders when the equipment is abnormal, and the operation of the balance and test cylinder can be viewed in real time through the monitoring camera; the present invention greatly saves manpower and material resources, and can obtain accurate and continuous monitoring data in unmanned areas that are difficult to complete manually; the cantilever-type weighing platform is combined with the inner and outer test cylinders, and the design method of the special protective cover can make the test cylinder fit the soil more accurately, and the data weighing accuracy can reach 0.01g, which can more accurately measure the bidirectional condensation amount; the design size of the outer cylinder meets the lifting requirements of the inner cylinder, which can not only meet the precise weighing, but also does not affect the dissipation of soil moisture; the data collection time can refer to 1 hour / time, and the weighing results of each time are collected and transmitted, and downloaded and analyzed on the data platform.

[0068] The present invention improves the measurement accuracy to 0.01g and the test tube weighing range to 5kg, greatly improving the accuracy and practicality of the equipment. At the same time, the system greatly improves the contact degree between the test tube and the soil, solves the problem that the condensation water part of the soil cannot be accurately measured, and greatly improves the reliability and availability of the data. The intelligent control mechanism matched with this system can realize indoor remote control of the low-consumption terminal in the field intelligent control box, and can be combined with the real-time monitoring effect of the monitoring camera, thereby realizing the remote control of the working and stopping status of the equipment to cope with sudden weather.
