Description

Technical Field

[0001] The invention relates to the technical field of agricultural irrigation, and in particular to an intelligent Malchow flask with adjustable water level. Background Art

[0002] The Malpighia flask, also known as the constant pressure flask, is a measuring device based on the principle of communicating vessels that can control the water level and automatically and continuously replenish water. During use, the height of the air inlet is usually adjusted to achieve the purpose of controlling the infiltration head. The Malpighia flask is widely used to control groundwater levels and soil infiltration and evaporation tests, and is often used as a constant pressure water supply measurement system in laboratories.

[0003] However, the Martens flasks currently available on the market, such as the UMS KSAT series soil saturated hydraulic conductivity measurement system, although the KSAT system has high accuracy, the equipment cost is high, the water head adjustment takes a long time, the capacity is small, and the air tightness of the rubber plug and the capillary connection port will decrease as the connection port loosens due to long-term plugging and unplugging. It is generally only suitable for indoor tests and cannot meet the needs of field infiltration and infiltration processes with large water consumption.

[0004] In the process of adjusting the water head in the existing Martens flask, a mechanical lifting platform or a method of padding something at the bottom of the Martens flask is often used. In this method, the entire Martens flask moves up and down when adjusting the water head. When water flows out from the water outlet of the Martens flask through the hose, due to the existence of the hose water head loss, the actual water head is often lower than the set water head. Therefore, the height of the Martens flask needs to be adjusted repeatedly. In addition, for a large-capacity Martens flask filled with water, this mechanical adjustment method is unsafe and time-consuming and labor-intensive. Summary of the invention

[0038] The following is combined with Figures 1 to 8 , the specific embodiments of the present invention are described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0039] like Figure 1 As shown, an intelligent water-level adjustable Martens flask provided by the present invention comprises a bottle body 8, a telescopic air inlet pipe, a height adjustment structure 4, and a magnetic bead valve 11. A scale 7 is arranged on the bottle body 8, and a bottle cap is arranged on the upper end of the bottle body 8. An air inlet and a water inlet are provided on the bottle cap. The air inlet is arranged on a side close to the scale 7 for easy reading. A water outlet is arranged at the lower end. A sealing plug 1 is arranged at the water inlet. The sealing plug 1 is preferably a rubber plug. The water outlet is connected to the magnetic bead valve 11. The telescopic air inlet pipe is vertically arranged in the bottle body 8, and its upper end is communicated with the air inlet. The height adjustment structure 4 is arranged on the bottle body 8, and its output end is connected to the telescopic air inlet pipe for adjusting the height of the lower end of the telescopic air inlet pipe. The height adjustment structure comprises an inner tube 3. The inner tube 3 is selected as a thin hard tube and is arranged in the telescopic air inlet pipe. The telescopic air inlet pipe is extended from the upper and lower ends thereof, the lower end is connected to the telescopic air inlet pipe, and the upper end is connected to a driving mechanism for driving the inner tube 3 to move up and down.

[0040] When in use, the driving mechanism drives the inner tube 3 to move up and down, and the limiting ball 10 at the lower end of the inner tube 3 moves accordingly. When moving upward, the limiting ball 10 pushes the telescopic air inlet pipe to compress, and the lower end of the telescopic air inlet pipe moves upward to increase the water head height. When the inner tube 3 moves downward, the telescopic air inlet pipe can freely extend to the height of the limiting ball 10 under the action of its own internal pressure, thereby reducing the water head height.

[0041] like Figure 2 As shown, the telescopic air inlet pipe includes a first hard tube 5, the upper end of which is connected to a spiral plug 12, the connection method between the first hard tube 5 and the spiral plug 12 is the common connection method of a telescopic straw, the spiral plug 12 is connected to the air inlet, the lower end is connected to a bellows 6, the lower end of the bellows is connected to a second hard tube 9, and an air outlet 13 is opened on the lower end tube wall of the second hard tube 9.

[0042] Since the air outlets 13 are arranged on both sides of the second hard tube 9 and are located at the upper end of the gap between the limiting ball 10 and the inner tube 3 , the gap between the limiting ball 10 and the inner tube 3 does not affect the water head height adjustment.

[0043] like Figure 3 As shown, the lower end of the second hard tube 9 is connected with a ball groove 23, and the lower end of the inner tube 3 is connected with a limiting ball 10. The limiting ball 10 is arranged in the ball groove 23. When the limiting ball 10 moves upward or downward, it can drive the ball groove 23 to move accordingly.

[0044] like Figures 4 to 7 As shown, the driving mechanism includes a mounting seat 14, which is arranged at the air inlet at the upper end of the bottle body 8. A through hole is opened on the mounting seat 14, and the through hole is connected to the telescopic air inlet pipe. A gear 15 (such as Figure 4 As shown), a groove for mounting a gear 15 is provided on the mounting seat 14, an outer peripheral surface of the inner tube 3 is provided with an external thread, an inner wall of the gear 15 is provided with an internal thread, and the inner tube 3 is threadedly connected to the gear 15.

[0045] When in use, by rotating the gear 15, the limiting ball 10 connected to the bottom of the inner tube 3 threadedly connected to the gear 15 drives the bellows to expand and contract, causing the air inlet height on the second hard tube 9 to change, thereby adjusting the water head height change. The operation is simple and the adjustment accuracy is high.

[0046] In order to reduce the resistance between the gear 15 and the mounting seat 14 and make the gear 15 rotate more smoothly, a steel ball 22 is embedded on the lower surface of the gear 15 .

[0047] Furthermore, a pull ring 2 is connected to the upper end of the inner tube 3. When in use, when the gear is not engaged with the capillary tube 3, the water level can be adjusted by pulling the pull ring up and down.

[0048] like Figure 8 As shown, the magnetic bead valve includes a tube body 17, in which a magnetic bead 20 with a magnetic pole is arranged. One end of the tube body 17 is connected to the water outlet, and a magnet 21 is rotatably arranged at the other end. The middle part of the tube body 17 is connected to the water outlet pipe 19, and the inner wall of the tube body 17 at the end away from the magnet 21 is connected to a retaining ring 16.

[0049] The intelligent water-level adjustable Martens flask of the present invention has the following assembly steps:

[0050] S1. Assemble the telescopic air intake pipe:

[0051] like Figure 2 The screw plug 12 and the first hard tube 5 are clamped by the telescopic straw principle, and the bellows is clamped between the first hard tube 5 and the second hard tube 9. The second hard tube 9 is provided with a plurality of gas outlets 13 on the bottom side, preferably two of which are provided here to speed up the speed of gas entering the water body, and at the same time, the gas outlets can be evenly balanced if they are provided on both sides;

[0052] S2. Assemble the main pipe body:

[0053] Insert the inner tube 3 into the telescopic air intake pipe, and at the same time, a thread is provided inside the lower side of the inner tube 3, and the inner tube 3 is screwed and fixed with the limiting ball 10, and then the ball groove 23 is connected to the second hard tube 9, so that the inner tube 3 and the telescopic air intake pipe form a main tube body, and a pull ring 2 is provided at the upper end of the inner tube 3. When a problem occurs in the driving mechanism, the pull ring 2 can be used to pull the inner tube 3 to move, and at the same time, other impurities in the air can be effectively prevented from entering. The main tube body is designed to be detachable. When the main tube body is damaged, the main tube body can be removed and replaced. The manufacturing process of the main tube body is simple, the raw materials are extensive, and the cost is low;

[0054] S3, assemble the Martens flask:

[0055] Insert the main pipe body assembled in S2 into the air inlet of the Martens flask. The air inlet is set at the edge of one side close to the scale 7 for easy reading. The position of the air inlet can also be adjusted as needed. Wrap the raw tape around the spiral of the screw plug 12 to prevent water leakage and air leakage. Then screw the screw plug 12 into the air inlet. Insert the sealing plug 1 of the equipment into the water inlet on the bottle cap, and connect the magnetic bead valve 11 to the water outlet at the bottom of the Martens flask. Figure 5 The left end of the magnetic bead valve is provided with a retaining ring 16 to prevent the magnetic bead 20 from moving out of the tube body 17, and the right end is provided with a rotatable strong magnetic magnet 21. The middle uses magnetic beads 20 with opposite magnetism on the left and right. The rotating strong magnetic magnet 21 drives the magnetic bead 20 to move left and right through the principle of like magnetic poles attracting each other and opposite magnetic poles repelling each other to control the opening and closing of the drain hole 18. Figure 1 The Martens flask is shown.

[0056] The present invention provides a method for using a smart water-level adjustable Martens flask, comprising the following steps:

[0057] S1, water inlet: rotating the magnet 21 drives the magnetic beads 20 to move toward one end of the bottle body 8, closing the water outlet pipe 19, removing the sealing plug 1, and adding water into the bottle body 8 from the water inlet;

[0058] S2, air tightness check: close the air inlet, and at the same time close the water inlet with the sealing plug 1, rotate the magnet 21, and the magnetic force drives the magnetic bead 20 to move away from the bottle body 8, the water outlet pipe 19 is connected with the bottle body 8, open the magnetic bead valve 11, no water flows out of the water outlet pipe 19, and water flows out of the water outlet pipe 19 after opening the air inlet, then the air tightness is normal, close the magnetic bead valve 11;

[0059] S3, water level adjustment: rotating the gear 15 to move the inner tube 3 up and down, so that the height of the air outlet 13 is flush with the preset water head height;

[0060] S4, rotating the magnet 21, the magnetic force drives the magnetic beads 20 to move in the direction away from the bottle body 8, the water outlet pipe 19 is connected with the bottle body 8, the magnetic bead valve 11 is opened, and constant pressure water supply is performed. When the soil surface water level is flush with the Malchnitz flask air outlet 13, the Malchnitz flask stops self-supplying water. When the soil surface water level is lower than the Malchnitz flask air outlet 13, the Malchnitz flask supplies water to the receiving water body again, and finally the purpose of constant pressure water supply is achieved.

[0061] To sum up, the present invention sets a driving mechanism for driving the inner tube to move up and down, and rotates the gear to make the inner tube threadably connected thereto move up and down. The limiting ball connected to the lower end of the inner tube drives the bellows to expand and contract to adjust the height of the air outlet on the second hard tube, thereby adjusting the water head height. The operation is simple and the adjustment accuracy is high.

[0062] The above disclosure is only a preferred specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
