Description
A rapid measurement device for water output during tunnel construction Technical Field
[0001] This utility model relates to the field of tunnel construction technology, and in particular to a rapid measurement device for water output during tunnel construction. Background Technology
[0002] During tunnel construction, measuring water output is crucial for project safety management. Currently, various measurement methods are commonly used. The traditional flowmeter method is relatively direct, calculating the water output by measuring the water velocity within the tunnel and combining it with the cross-sectional area. However, it is complex to operate, and in confined, turbulent, and complex tunnel environments, instrument placement is difficult, and measurement accuracy is easily affected by turbulence. The weir method is suitable for areas with relatively stable water flow and where weirs can be constructed at the outlet. It calculates the flow rate by measuring the head above the weir. However, weir construction is time-consuming and alters the flow pattern, affecting subsequent construction. Emerging methods such as electromagnetic flowmeters and ultrasonic flowmeters utilize the electromagnetic induction or acoustic characteristics of water flow for measurement. They are easy to install and can monitor in real time, but their adaptability to sandy water flows is poor. Sediment abrasion can easily damage the probe, affecting its service life and accuracy.
[0003] In current tunnel construction practices, although there are various water output measurement technologies available, they have many shortcomings: under complex geological conditions, such as karst tunnels, water inrush points are scattered and water flow paths are varied, making it difficult to capture the water output from multiple sources simultaneously; in small and medium-sized projects, the cost of measurement equipment remains high, making it difficult to afford for projects with limited budgets.
[0004] Therefore, there is a lack of a simple measuring device that is both economical and convenient, can be quickly deployed, and can meet basic measurement needs. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a rapid measurement device for water output during tunnel construction, in response to the above-mentioned problems.
[0006] The technical solution adopted by this utility model is: a rapid measurement device for water output during tunnel construction, comprising:
[0007] The water collection umbrella assembly has a top collection port that can be scaled and adjusted to accommodate multiple dispersed water outlets at the top of the tunnel.
[0008] The water storage component is detachably located at the bottom of the water collection umbrella component. It has a water storage cavity that can communicate with the bottom of the water collection umbrella component. It is used to store the water collected by the water collection umbrella component and can adjust the preset capacity of the water storage cavity.
[0009] A timing component, located at the top outer edge of the water storage component, is used to record the water collection time.
[0010] By using the aforementioned technical means, the top collection port of the water umbrella component can be adjusted and scaled to allow the device to flexibly adapt to multiple water outlets with different spacing and distribution within a local area. This enables the same device to collect water at multiple locations, improving the coverage of dispersed water sources. The water storage component can store the water collected by the water umbrella component, and the timing component can record the water collection time. Combined with the preset capacity of the water storage cavity and the water collection time, it is convenient to quickly measure the water output during tunnel construction.
[0011] In some embodiments, the water collecting umbrella assembly includes an umbrella canopy, an umbrella pole, and umbrella cords. The top of the umbrella pole is connected to the umbrella canopy via the umbrella cords. The umbrella pole itself is telescopic and adjustable. The first end opening of the umbrella canopy is the collection port, and the second end opening of the umbrella canopy is connected to the top of the water storage assembly. The opening area of the first end opening of the umbrella canopy is larger than the opening area of the second end opening. The opening angle of the umbrella can be changed by adjusting the length of the umbrella pole, thereby adjusting the opening area of the first end opening of the umbrella canopy.
[0012] In some embodiments, the water storage assembly includes a water collection tank and a fixed support member. The water collection tank has a multi-level telescopic folding structure, with adjacent levels connected by the fixed support member. The top of the water collection tank is detachably connected to the water collection umbrella assembly via a connector. The timing component is installed on the outer edge of the top of the water collection tank, and a drain outlet is provided on the top of the water collection tank.
[0013] In some embodiments, the fixed support includes a buckle and a snap-fit post. The outer wall of the water collection tank is provided with a plurality of snap-fit posts, each of which corresponds to a folding layer. The buckle and the snap-fit post can be snapped together to achieve extended support for adjacent folding layers.
[0014] In some embodiments, the connector includes a snap-fit connection structure or a threaded connection structure.
[0015] In some embodiments, the outer wall of each folded layer of the water collection bucket is marked with the volume value of the water that layer can store.
[0016] In some embodiments, waterproof strips are provided at the gaps between adjacent folded layers of the water collection tank.
[0017] In some embodiments, the diameter of each folded layer of the water collection bucket increases sequentially from bottom to top, so as to achieve tight nesting when folding and unfolding.
[0018] In some embodiments, the timing component includes a timer, a switch button, and a timer start / stop button. The switch button and the timer start / stop button are electrically connected to the timer. The switch button, the timer start / stop button, and the timer are all installed on the top of the water storage component. The switch button is used to control the timer to turn on and off, and the timer start / stop button is used to control the start and stop of the timer.
[0019] The beneficial effects of this utility model are:
[0020] 1. By adjusting the size of the collection port at the top of the water collection umbrella assembly, the size of the collection port corresponds to multiple scattered water outlets within a localized area at the top of the tunnel. The adjusted collection port can simultaneously collect water from multiple scattered outlets, improving coverage of dispersed water sources and adapting to complex geological conditions. A water storage assembly stores the water collected by the water collection umbrella assembly. The water storage chamber of the water storage assembly can be adaptively adjusted according to different water volume scenarios. By adjusting the water collection range and space, the applicability of the device is enhanced.
[0021] 2. By detachably connecting the water collection umbrella assembly and the water storage assembly, transportation, disassembly and replacement, and rapid on-site deployment are facilitated. Using a simple timing component to record water collection time, combined with the known preset capacity of the water storage assembly and the recorded collection time, the water output per unit time within the tunnel can be quickly calculated. Replacing high-cost electromagnetic and ultrasonic flow meters with the timing component effectively reduces the cost of the device for small to medium-sized projects with limited budgets, ensuring economic practicality.

[0031] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.
[0032] Example 1:
[0033] Referring to Figures 1 to 4, this embodiment is a rapid water output measurement device during tunnel construction, including a water collection umbrella assembly 3, a water storage assembly, and a timing assembly. The water storage assembly has an opening at the top and a water storage cavity connected to the top opening inside. The water storage assembly can adjust the preset capacity of the water storage cavity. The water collection umbrella assembly 3 is detachably connected to the top of the water storage assembly. The water collection umbrella assembly 3 has an umbrella-shaped structure, and the collection port at the top of the water collection umbrella assembly 3 can be adjusted to accommodate multiple dispersed water outlets at the top of the tunnel. The water from the outlets is guided through the collection port of the water collection umbrella assembly 3 to the water storage cavity of the water storage assembly, where the collected water is stored. A timing assembly is located on the outer edge of the top of the water storage assembly to record the water collection time.
[0034] In some implementations, the water storage assembly includes a water collection tank 1 and a fixed support. The water collection tank 1 has a multi-layer telescopic folding structure, with adjacent layers connected by the fixed support. The top of the water collection tank 1 is detachably connected to the water collection umbrella assembly 3 via a connector 31. A timing component is installed on the outer edge of the top of the water collection tank 1. As shown in Figure 2, the top folding layer of the water collection tank 1 has a drain outlet 13. Water flowing from the drain outlet 13 indicates that the water collection tank 1 is full.
[0035] Furthermore, the fixing support includes a buckle 12 and a snap-fit post. The outer wall of the water collection tank 1 is provided with multiple snap-fit posts, each corresponding to a different folding layer. The buckle 12 and the snap-fit post can be snapped together to achieve extended support for adjacent folding layers under tension. Specifically, in this embodiment, the buckle 12 is made of plastic or metal, which can prevent the connection between the folding layers from failing due to the weight of the water during water measurement, thereby ensuring the structural stability of the water collection tank 1 under tension.
[0036] Furthermore, the diameter of each folded layer of the water collection bucket 1 increases sequentially from bottom to top, giving it a top-smaller, bottom-larger shape. This allows for tight nesting during folding and unfolding, reducing space usage. Simultaneously, this structural design allows for adjustment of some layers of the water collection bucket 1 to accommodate varying drainage volumes within the tunnel.
[0037] Furthermore, the outer walls of each folded layer of the water collection bucket 1 are marked with the corresponding volume value that layer can store water. Specifically, during the manufacture of the water collection bucket 1, the volume of each layer is precisely calculated, ensuring that the volume of each layer of the water collection bucket 1 is a known value, and this is clearly marked on the outside of each layer. When measuring the water output, staff only need to observe the number of layers in the water collection bucket 1 that are filled with water, and add the volumes of the corresponding layers to quickly obtain the total volume of collected water.
[0038] Furthermore, a waterproof strip is provided at the gap between adjacent folded layers of the water collection tank 1. In this embodiment, the waterproof strip is made of materials with good waterproof performance, such as rubber, which can effectively prevent water from seeping out from the gap between the folded layers and ensure the sealing of the water collection process.
[0039] In some implementations, as shown in Figure 3, the water collection umbrella assembly 3 includes an umbrella canopy 32, an umbrella pole 33, and umbrella lines 34. The top of the umbrella pole 33 is connected to the umbrella canopy 32 via the umbrella lines 34. The first end opening of the umbrella canopy 32 is a collection port, and the second end opening of the umbrella canopy 32 is connected to the top of the water storage assembly. The opening area of the first end of the umbrella canopy 32 is larger than that of the second end opening, resulting in a relatively light umbrella mass and minimal impact on stability. The umbrella pole 33 is a multi-section telescopic structure. Stretching and scaling the umbrella pole 33 can control its length. Adjusting the length of the umbrella pole 33 can change the opening angle of the umbrella canopy 32, thereby adjusting the opening area of the first end of the umbrella canopy 32 to adapt to situations where water outlets are dispersed and water flow paths are variable under complex geological conditions.
[0040] By adopting a multi-layered folding water collection tank 1, it is not only easy to carry, but also allows for flexible adjustment of the water collection space according to the actual water output. Furthermore, the water collection space can be flexibly adjusted by adjusting the folding layers to adapt to different measurement needs, avoid resource waste and unnecessary time consumption, and improve measurement efficiency.
[0041] Furthermore, in this embodiment, the umbrella surface 32 is made of waterproof fabric, which has good waterproof performance and can effectively collect water flow.
[0042] Furthermore, in this embodiment, the connector 31 includes a snap-fit connection structure or a threaded connection structure to facilitate the installation and disassembly of the umbrella surface 32 and the water collection tank 1.
[0043] In some implementations, as shown in Figure 4, the timing component includes a timer 2, a switch button 21, and a timing start / stop button 22. Both the switch button 21 and the timing start / stop button 22 are electrically connected to the timer 2. All three buttons, along with the timer 2, are mounted on the top of the water collection tank 1. The switch button 21 is used to turn the power to the timer 2 on or off, and the timing start / stop button 22 is used to control the start and stop of the timer 2. When measuring the water output, pressing the timing start / stop button 22 starts the timing. When the water collection tank 1 is full or the predetermined water collection time has been reached, pressing the timing start / stop button 22 again stops the timing. By recording the water collection time and the volume of the water collection tank 1, the water output per unit time during the tunnel construction period can be calculated.
[0044] The implementation principle of a rapid water output measurement device during tunnel construction is as follows:
[0045] The umbrella surface 32 can be flexibly adjusted to change its unfolding angle according to the distribution of water outlets on site. This not only adapts to different spatial conditions and improves environmental adaptability, but also covers multiple scattered water outlets simultaneously, enhancing the ability to capture water from multiple sources and improving water collection efficiency. The umbrella surface 32 in this device has a funnel-shaped contraction structure, which helps to concentrate the water flow into the water collection tank 1 and reduce overflow loss.
[0046] The water collection tank 1 adopts a multi-level folding structure, which saves storage and transportation space and facilitates rapid deployment on-site. The water storage capacity can be flexibly adjusted according to the actual water output by expanding to the corresponding level. The volume of each level is clearly marked on the outer wall. From a practical engineering perspective, the accuracy of water output during construction is usually not very high, but data acquisition efficiency is crucial. Therefore, this device can quickly determine the total water volume by simply accumulating the approximate number of levels that are full. In practical applications, the metering volume is controlled by selecting an appropriate combination of levels to meet the practical needs of the engineering scenario. For example, for tunnels with small drainage volumes, smaller volume levels are preferred as they are easier to fill, while for tunnels with large drainage volumes, excessively small volumes are inconvenient for time measurement. The levels are connected by snap-fit 12 to provide stable support, preventing structural collapse or deformation due to water weight.
[0047] The top folded layer of the water collection tank 1 also has a drain outlet, which is not affected by folding. When water flows from the drain outlet 13, it indicates that the water collection tank 1 is full. That is, the start of water flow from the drain outlet 13 means that the water collection tank 1 is full and the collected water volume is known. At this time, pressing the timer start / stop button 22 will obtain the time it took to collect the corresponding volume of water. By directly emptying the water in the water collection tank 1 after measurement, the water collection tank 1 can be quickly emptied, resulting in high reuse efficiency.
[0048] The water collection umbrella assembly 3 and the water storage assembly are detachably connected via a snap-fit or threaded connection structure. Assembly and disassembly can be completed on-site without tools, improving work efficiency. Both the snap-fit 12 and the threaded structure provide good locking force, ensuring structural stability during measurement.
[0049] Example 2:
[0050] This embodiment describes a method for using a rapid water output measurement device during tunnel construction, applied to the rapid water output measurement device during tunnel construction in Embodiment 1, and includes the following steps:
[0051] S1, Equipment Preparation Stage
[0052] When carrying the equipment to the tunnel construction surveying site, the water collection bucket 1 should be completely folded up. This minimizes the space occupied by the water collection bucket 1, making it easier for workers to transport and move it in the narrow and complex tunnel environment. Simultaneously, the umbrella pole 33 should be retracted to reduce obstruction during transport.
[0053] Once the measurement location is reached, the number of layers to be unfolded in the water collection tank 1 is determined based on the estimated water outflow from the tunnel. If the estimated outflow is small, only the unfolded folding layers need to be selected. The selected unfolded folding layers are pulled open one by one, and then they are firmly fixed using the buckles 12 between each layer to ensure that the folding layers will not accidentally retract during the water collection process.
[0054] Based on the distribution of water inrush points and the water flow path in the tunnel, the umbrella surface 32 in the water collection umbrella assembly 3 is adjusted. The opening angle of the umbrella surface 32 is changed by stretching or contracting the umbrella rod 33. If the water inrush points are concentrated, the opening angle of the umbrella surface 32 can be appropriately reduced; if the water inrush points are scattered, the opening angle of the umbrella surface 32 can be increased to ensure that the umbrella surface 32 can collect water to the maximum extent. After adjusting the opening angle of the umbrella surface 32, the umbrella surface 32 is connected to the water collection tank 1 using the connector 31.
[0055] If the connector 31 adopts a snap-on connection structure, align the snap 12 on the water collecting umbrella with the slot on the water collecting tank 1 and press it firmly to lock it in place; if the connector 31 adopts a threaded connection structure, screw the connecting end of the umbrella surface 32 into the corresponding threaded interface of the water collecting tank 1 until it is tightened, thus completing the installation of the umbrella surface 32 and the water collecting tank 1.
[0056] S2, Measurement Phase
[0057] Turn on the power switch 21 of timer 2 to put it into operation. Press the start / stop button 22 to start timer 2 and record the start time of water collection.
[0058] Water flows into the water collection tank 1 through the adjusted umbrella surface 32, and staff closely monitor the water collection status of the water collection tank 1. When the water collection tank 1 is full or the preset water collection time is reached, the timer start / stop button 22 is pressed again, the timer 2 stops timing, and the end time of water collection is recorded, thus accurately obtaining the time used for water collection.
[0059] S3, Calculation of water output stage
[0060] Observe the number of layers filled with water in water collection bucket 1. Based on the known volume values clearly marked on the outside of each layer, add up the volumes corresponding to the number of layers filled with water to quickly and accurately obtain the total volume of water collected.
[0061] According to the formula: Water output per unit time = Volume of water collection bucket 1 (i.e., total water collection volume) ÷ Water collection time, the water output per unit time during the tunnel construction period can be calculated.
[0062] S4. Post-measurement processing stage
[0063] After the measurement is completed, pour out the water collected in water collection bucket 1.
[0064] To remove the canopy 32, if it is a snap-on connection, press and hold the release button on snap 12 to remove the canopy 32 from the water collection tank 1; if it is a threaded connection, rotate the connecting end of the canopy 32 in the opposite direction to remove it from the water collection tank 1. Then fold up the canopy 32 of the water collection umbrella.
[0065] Fold each layer of the water collection bucket 1 in sequence to restore it to a portable state, preparing it for the next measurement.
[0066] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
