Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of soil physics experimental equipment, and in particular to a portable adjustable capacity water supply Marshall bottle device. Background Technology
[0002] The Marvin flask is a constant-pressure water supply device designed based on the principle of communicating vessels, widely used in experiments in hydrology, soil science, and agricultural water conservancy projects. Its core principle is to connect to the atmosphere through an internal air inlet pipe, allowing the water pressure inside the flask to be dynamically regulated by the gas input at the lower end of the inlet pipe, thus ensuring a constant water pressure at the outlet of the Marvin flask. For example, in soil infiltration experiments, the Marvin flask maintains a constant level of surface water by adjusting the height of the lower end of the air inlet pipe.
[0003] In practical applications, traditional plexiglass Marvi bottles have several shortcomings: First, traditional Marvi bottles typically employ a rigid structure with a fixed volume, severely limiting experimental flexibility. When faced with diverse experimental scenarios such as different plant water requirements, soil infiltration rates, or hydrological process simulations, they cannot dynamically adjust the water storage volume to match differentiated water supply needs. Therefore, multiple Marvi bottles of different sizes are usually required to meet experimental needs, leading to increased equipment costs and reduced experimental efficiency. Second, traditional Marvi bottles generally lack integrated mobile auxiliary structures; the bottle body... Traditional Marvi bottles are typically smooth cylinders, requiring operators to directly contact the bottle body when moving or adjusting its position. This increases the risk of slippage, causing the apparatus to tip over or spilling liquid, and poses a safety hazard during frequent repositioning. Thirdly, the fixed-length inlet tube of traditional Marvi bottles cannot be flexibly adjusted according to changes in water level or the precision required for head control during experiments. When precise control of a constant head at different heights is needed, traditional devices can only achieve this by adjusting the bottle height, leading to decreased stability and increased operational steps and time costs. This makes it difficult to meet the stringent requirements of dynamic head adjustment in high-precision experiments. In summary, traditional plexiglass Marvi bottles have certain shortcomings in durability, environmental adaptability, and ease of operation. Utility Model Content
[0004] Purpose of the utility model: In view of the above problems, the purpose of this utility model is to provide a portable adjustable capacity water supply Marshall bottle device, which optimizes the structure, makes the operation more convenient, realizes the capacity adjustment, reduces the cost, and facilitates its widespread use.
[0005] Technical solution: A portable adjustable capacity water supply Marshall bottle device includes an integrated handle, a telescopic wall, a water inlet, a detachable air inlet pipe, a water outlet valve, and a vertical scale. The telescopic wall is a hollow columnar structure with a telescopic pleated structure on its outer periphery and a barrel-shaped structure at the bottom. The integrated handle is installed on the top of the telescopic wall. The top of the telescopic wall is also equipped with a detachable air inlet pipe and a water inlet. The water outlet valve is located at the bottom of the telescopic wall, and the vertical scale is installed on the top of the telescopic wall.
[0006] Furthermore, the detachable intake pipe includes a hollow threaded cap, an upper fixed pipe, and a lower telescopic pipe. The hollow threaded cap and the upper fixed pipe are fixedly connected as an integral structure. The central area of the hollow threaded cap has a through-hole design, and its axis is coaxially aligned with the axis of the upper fixed pipe. The lower telescopic pipe passes through the top of the upper fixed pipe. The axial cross-section of both the upper fixed pipe and the lower telescopic pipe is an inverted frustum shape. The outer diameter of the upper end of the lower telescopic pipe is smaller than the inner diameter of the upper end of the upper fixed pipe and larger than the inner diameter of the lower end of the upper fixed pipe, so that the upper fixed pipe and the lower telescopic pipe can slide relative to each other.
[0007] Ideally, the top of the telescopic wall is equipped with an external threaded interface, and the detachable air intake pipe is detachably connected to the telescopic wall through the external threaded interface. The inner circumferential wall of the hollow threaded cover is threaded, and the external threaded interface and the internal thread of the hollow threaded cover form a screw-fit engagement.
[0008] Furthermore, the vertical scale also includes a fixing plate, a knob, a rotating shaft, a measuring tape groove, a measuring tape, and a counterweight. The fixing plate is made of two symmetrical pieces of plexiglass material, which are bolted together and horizontally fixed to the top of the telescopic wall and located on one side of the integrated handle. One end of the fixing plate is suspended relative to the top of the telescopic wall. The measuring tape groove is rotatably connected to the suspended end of the fixing plate through the rotating shaft. The knob is installed on one end of the rotating shaft. The measuring tape is wound around the measuring tape groove. The starting end of the measuring tape has a through hole, and the counterweight is suspended at the through hole so that the measuring tape is kept vertical by gravity during use.
[0009] Ideally, the telescopic wall should be made of silicone and / or environmentally friendly PP materials, with a maximum stretch angle of 75° for its main telescopic pleated structure.
[0010] Ideally, the one-piece handle should have an arc or U-shaped structure and a non-slip texture on the surface.
[0011] Ideally, the water injection port adopts a hexagonal bolt structure, which forms a detachable screw-in connection with the top of the telescopic wall through a screw-in threaded pair.
[0012] Beneficial effects: Compared with the prior art, the advantages of this utility model are:
[0013] This invention employs a retractable pleated structure design, made of silicone and / or PP environmentally friendly materials, solving the problem of fixed volume in traditional Marshall bottles and their inability to adapt to different experimental water supply needs, thus achieving dynamic adjustment of water storage volume. An integrated U-shaped anti-slip handle addresses the inconvenience of moving traditional devices and their tendency to tip over due to slippage, allowing for convenient hand operation and movement by the operator. A detachable air inlet pipe (including a hollow threaded cap, an upper fixed pipe, and a lower telescopic pipe, forming a sliding sleeve structure through interference fit) solves the problem of non-adjustable air inlet pipe length and frequent device replacement, enabling a single device to adapt to different pressure heads. The screw-fit between the external threaded interface and the hollow threaded cap solves the problem of easy leakage and air leakage in traditional devices, ensuring reliable container sealing. A vertical scale with a counterweight allows for dynamic reading of the liquid level within the retractable wall.
[0014] In summary, this portable adjustable Marshall bottle device effectively solves the problems of fixed volume, inconvenient movement, cumbersome air inlet pipe adjustment, easy leakage, and insufficient reading accuracy of traditional Marshall bottles. It achieves the advantages of dynamic adjustment of water storage volume, convenient operation, flexible water head adaptation, reliable sealing, and accurate measurement. Attached Figure Description

[0022] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0023] A portable, adjustable-capacity water supply Marshall bottle device, such as Figures 1-7As shown, it includes an integrated handle 1, a telescopic wall 2, a water inlet 3, a detachable air inlet pipe 4, a water outlet valve 5, and a vertical scale 6.
[0024] The main body of the telescopic wall 2 adopts a telescopic pleated structure design, specifically made of silicone and / or PP environmentally friendly materials through injection molding, extrusion and other processes to form a pleated structure; the maximum stretching angle of the pleated structure is 75°; the top of the telescopic wall 2 is equipped with an external threaded interface 21; the pleated structure is evenly distributed on the wall, and the water storage volume of the device can be dynamically adjusted by the extension and contraction of the pleated structure, and the water storage volume can be increased by up to 200% to adapt to the water supply needs of different experiments.
[0025] The top of the telescopic wall 2 is equipped with an integrated handle 1, a detachable air inlet pipe 4, a water inlet 3, and a vertical scale 6; the integrated handle 1 has an arc or U-shaped structure and an anti-slip texture on the surface, which makes it easy for operators to hold and move the bottle, improving the ease of use.
[0026] The detachable air intake pipe 4 includes a hollow threaded cap 41, an upper fixed pipe 42, and a lower telescopic pipe 43. The hollow threaded cap 41 and the upper fixed pipe 42 are fixedly connected as an integral structure. The central area of the hollow threaded cap 41 has a through-hole hollow design, and its axis is coaxially aligned with the axis of the upper fixed pipe 42. The lower telescopic pipe 43 is installed through the top of the upper fixed pipe 42. The outer diameter of the upper end of the lower telescopic pipe 43 is slightly larger than the inner diameter of the lower end of the upper fixed pipe 42. Through an interference fit, a relatively sliding and fixed-position sleeve structure is formed, so that the entire pipe body has the function of telescopic adjustment. Through the relative sliding of the upper fixed pipe 42 and the lower telescopic pipe 43, the length of the pipe body can be flexibly adjusted to adapt to the needs of water head control conditions at different heights.
[0027] The external threaded interface 21 is located on the top of the telescopic wall 2, forming a screw-fit with the internal thread of the hollow threaded cap 41. The threaded engagement allows for quick installation, removal, and length adjustment of the telescopic tube. Simultaneously, the sealing structure of the threaded mating surface prevents liquid leakage, ensuring container sealing and ease of operation. The water injection port 3 uses a hexagonal bolt structure, forming a detachable screw-fit connection with the top of the telescopic wall 2 through a screw-in threaded pair, enabling rapid water injection and sealing. During use, the threaded mating surface effectively prevents gas leakage, ensuring reliable sealing.
[0028] The vertical scale 6 comprises a fixed plate 61, a knob 62, a rotating shaft 63, a measuring tape groove 64, a measuring tape 65, and a counterweight 66. The fixed plate 61 is made of two symmetrical pieces of plexiglass material, which are bolted together and fixed to the left side of the integrated handle 1 to form a stable support base. The measuring tape groove 64 is located on the left side of the fixed plate 61 and is rotatably connected to the rotating shaft 63. The knob 62 is fixedly connected to the top of the rotating shaft 63, and the rotation state of the measuring tape groove 64 is controlled by operating the knob 62. The measuring tape 65 is wound around the measuring tape groove 64 and rotates with it to achieve retraction and extension. The starting end of the measuring tape 65 has a through hole, and the counterweight 66 is suspended at the through hole to keep the measuring tape 65 vertical during use, so as to realize dynamic reading of the liquid level in the telescopic wall.
[0029] The method of use and working principle of this utility model are as follows:
[0030] Before use, install the vertical scale 6 on the left end of the integrated handle 1, fix the measuring tape 65 on the measuring tape groove 64, turn the knob 62 to drive the rotating shaft 63 and the measuring tape groove 64, so that the measuring tape 65 is wound around the measuring tape groove 64, hang the counterweight 66 at the bottom through hole of the measuring tape 65, so that the measuring tape 65 is vertically and freely stretched to the bottom of the telescopic wall 2, and record the height of the telescopic wall 2. According to the required water storage volume for the experiment, press down or stretch the telescopic wall 2 along the height direction, and use the elastic deformation characteristics of its wavy pleated structure to adjust the water storage volume inside the bottle to the target value by compressing or stretching the pleats. Subsequently, adjust the upper fixed tube 42 and the lower telescopic tube 43 in the detachable air inlet tube 4, stretching or compressing the lower telescopic tube 43 axially until its lower end face is aligned with the outlet end face of the water outlet valve 5, forming a telescopic tube length that matches the current height of the telescopic wall 2; tighten the hollow threaded cap 41 to vertically fix the entire telescopic tube inside the telescopic wall 2, ensuring the stability of the tube structure. Then, unscrew the water inlet cap 3 and fill with water; observe the water level changes inside the telescopic wall 2 during the water filling process, fill the bottle to full, complete the water filling operation, and reinstall the water inlet cap 3 back in its original position. After water filling, check the sealing of each connection part; once confirmed to be correct, the experiment can proceed to the usage stage.
[0031] In summary, the portable adjustable-capacity Marviate flask device provided by this invention effectively addresses the shortcomings of traditional acrylic Marviate flasks in terms of durability, environmental adaptability, and ease of operation. Its core features include a telescopic wall with pleats evenly distributed along the height of the flask. The expansion and contraction of these pleats dynamically adjusts the water storage volume (up to 200%), flexibly adapting to the water storage needs of different experimental scenarios. The integrated handle on top significantly enhances the device's portability. The detachable air inlet tube not only allows for quick and leak-proof sealing through a screw-on operation but also allows for flexible adjustment of the tube length by stretching or retracting the telescopic tube, precisely adapting to different head control conditions. A vertical scale facilitates clear recording of water usage by the experimenter. Overall, this device combines advantages such as compact structure, convenient operation, strong adaptability, and economical cost, providing a more efficient tool option for hydrological, soil science, and agricultural water conservancy engineering experiments.
