Abstract
Description
Technical Field
[0001] This application relates to the field of water level measurement technology, and in particular to a precipitation observation device. Background Technology
[0002] To prevent groundwater from flowing into the mine tunnels and causing loss of life and property, mine water hazard prevention measures include leaving water-resistant coal pillars and releasing groundwater in advance. The design of the height of the water-resistant coal pillars not only needs to take into account other waterproofing measures underground, but also needs to match seasonal rainfall. The Quaternary loose aquifer has a greater impact on the roof of the steeply inclined shallow coal mining face. The Quaternary loose aquifer is directly replenished by atmospheric rainfall, that is, the water level of the Quaternary loose aquifer is related to the amount of precipitation.
[0003] In related technologies, when using regional meteorological data to obtain precipitation data for mining areas, the calculation error is relatively large when analyzing the correlation between water inflow and precipitation in the mining area because regional meteorological data is a regional average precipitation. This can easily lead to mine personnel misjudging whether water hazards will occur in the mine. Therefore, it is necessary to obtain timely and accurate precipitation data for the mining area to determine whether water hazards will occur in the mine. Utility Model Content
[0004] The purpose of this application is to obtain the precipitation in the mining area within a preset time period in a timely and accurate manner, so as to improve the accuracy of analyzing the correlation between the water inflow and precipitation in the mining area, thereby determining whether water hazards will occur in the mine.
[0005] To achieve the above objectives, this application provides a precipitation observation device.
[0006] The precipitation monitoring device according to this application includes: a rain collection tank, wherein a water accumulation cavity is provided inside the rain collection tank, the water accumulation cavity forming an opening on the top wall of the rain collection tank, and the water accumulation cavity is pre-filled with water; a measuring element, wherein the measuring element is movably installed inside the water accumulation cavity and extends outside the rain collection tank, the measuring element floats on the water and is adapted to move relative to the rain collection tank along the height direction of the rain collection tank according to the change in the water level in the water accumulation cavity, and the outer peripheral wall of the measuring element is provided with a height indication mark; and a positioning component, wherein the positioning component is sleeved on the outer peripheral side of the measuring element, the positioning component is fixedly connected to the inner peripheral wall of the rain collection tank to limit the measuring element radially within the water accumulation cavity of the rain collection tank, and the top wall of the positioning component forms a current mark. The initial marking surface is determined by reading the height indicator mark at the same height as the current marking surface. An initial marking component is movably fitted onto the outer periphery of the measuring component and located above the positioning component. The initial marking component includes a marking ring movably fitted onto the outer periphery of the measuring component. The bottom wall of the marking ring is adapted to abut against the top wall of the positioning component. The bottom wall of the marking ring is constructed as an initial marking surface. The initial relative height position between the measuring component and the rain collection tank is determined by reading the height indicator mark at the same height as the initial marking surface.
[0007] According to the precipitation observation device of this application, rainwater in the mine area is collected by a rain collection tank. Then, the initial height position of the measuring element in the water accumulation cavity is read using the initial marker surface, and the current height position of the measuring element in the water accumulation cavity is read using the current marker surface. The difference between the two can determine the height change of the measuring element in the water accumulation cavity, and the water level change of the water accumulation cavity within a preset time can be determined. Thus, the precipitation in the mine area within a preset time can be obtained. Compared with the prior art, using the precipitation observation device of this application to observe the precipitation in the mine area and analyze the correlation between mine water inflow and precipitation can reduce the calculation error during analysis, thereby effectively preventing water hazards in the mine.

[0010] In some examples of this application, one of the first guide structure and the second guide structure is a guide rod, and the other of the first guide structure and the second guide structure is a guide hole. The guide rod extends radially along the rain collection tank and is inserted into the guide hole. The outer periphery of the guide rod is provided with an elastic element that can be elastically deformed. The elastic element is used to drive the limiting ring and the limiting bracket to move closer or further apart.
[0011] In some examples of this application, the cross-section of the guide rod is polygonal, and the cross-section of the guide rod is perpendicular to the axial direction of the guide rod.
[0012] In some examples of this application, the end of the guide rod inserted into the guide hole is provided with a stop member, which is adapted to abut against the side wall of the guide hole.

[0028] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.
[0029] like Figures 1-5 As shown in the illustration, a precipitation observation device 100 according to an embodiment of this application can be used for water hazard prevention in mining areas. However, this application is not limited to this; the precipitation observation device 100 can also be used in other scenarios that require precipitation measurement, such as construction sites and manhole construction. Furthermore, the precipitation observation device 100 of this application can also be directly used for weather forecast data statistics.
[0030] like Figures 1-5As shown, the precipitation observation device 100 according to an embodiment of this application includes: a rain collection tank 1, a measuring component 2, a positioning component 3, and an initial marking component 4. The rain collection tank 1 is provided with a water accumulation chamber 11, which has an open opening on its top wall. When using the precipitation observation device 100 in a mining area, the rain collection tank 1 can be placed on flat ground. The water accumulation chamber 11 is used to collect rainwater, which flows into the water accumulation chamber 11 through the open opening on the top wall of the rain collection tank 1. The change in water level within the water accumulation chamber 11 over a preset time is the precipitation amount within that preset time.
[0031] Measuring element 2 is movably installed inside the water collection chamber 11, with one end extending outside the rainwater collection tank 1. Measuring element 2 floats on the collected water and is adapted to move relative to the rainwater collection tank 1 along its height direction according to changes in the water level within the water collection chamber 11. Specifically, when the water level in the water collection chamber 11 rises, measuring element 2 moves upward relative to the rainwater collection tank 1 along its height direction; when the water in the water collection chamber 11 is discharged, causing the water level to drop, measuring element 2 moves downward relative to the rainwater collection tank 1 along its height direction. It should be noted that the height direction of the rainwater collection tank 1 is... Figure 2 In the vertical direction, the height direction of measuring component 2 is consistent with the height direction of rain collection tank 1.
[0032] Furthermore, the positioning component 3 is sleeved on the outer periphery of the measuring component 2, and the positioning component 3 is fixedly connected to the inner peripheral wall of the rain collection tank 1. That is to say, the positioning component 3 is supported between the measuring component 2 and the inner peripheral wall of the rain collection tank 1. The positioning component 3 is used to limit the measuring component 2 radially within the water collection cavity 11. When the measuring component 2 moves with the change of water level in the water collection cavity 11, the positioning component 3 can reduce the radial swaying of the measuring component 2 within the water collection cavity 11, thereby making it easier for staff to determine the amount of rainfall by the relative height position between the measuring component 2 and the rain collection tank 1.
[0033] Furthermore, a height indicator 21 is provided on the outer peripheral wall of the measuring component 2. In some specific embodiments, the height indicator 21 can be a size scale, which consists of multiple scale lines arranged sequentially and at intervals along the height direction of the measuring component 2. Each scale line represents a corresponding height dimension. The top wall of the positioning component 3 forms a current marking surface 31. By reading the height indicator 21 at the same height position as the current marking surface 31, the current relative height position between the measuring component 2 and the rainwater collection tank 1 is determined. Furthermore, by reading the height indicator 21 at the same height position as the current marking surface 31 at the current moment and the height indicator 21 at the same height position as the current marking surface 31 at the previous moment, and then calculating the difference between the two readings, the water level change in the water accumulation chamber 11 between the previous moment and the current moment can be obtained, thereby determining the rainfall during the time period between the previous moment and the current moment.
[0034] Of course, in the embodiments of this application, the precipitation over the time interval from the initial moment to the current moment can also be calculated to determine the water inflow in the mine area. For example... Figures 1-3 As shown, the precipitation observation device 100 obtains the initial height position between the measuring element 2 and the rain collection tank 1 at the initial moment through the initial marking component 4. The initial marking component 4 is movably sleeved on the outer periphery of the measuring element 2 and is located above the positioning component 3. The bottom wall of the initial marking component 4 forms an initial marking surface. Specifically, the initial marking component 4 includes a marking ring 43, which is movably sleeved on the outer periphery of the measuring element 2. The bottom wall of the marking ring 43 is adapted to abut against the top wall of the positioning component 3, and the bottom wall of the marking ring 43 is constructed as the initial marking surface. The initial height position of the measuring element 2 in the rain collection tank 1 is determined by reading the height indicator 21 at the same height position as the initial marking surface.
[0035] It should be understood that when the water level in the water collection chamber 11 is too low, causing the buoyancy of the water acting on the measuring element 2 to be less than the weight of the measuring element 2, the water in the water collection chamber 11 is insufficient to suspend the measuring element 2 on the water surface. During the process of the water level rising in the water collection chamber 11, the measuring element 2 will first remain stationary relative to the rainwater collection tank 1 until the buoyancy of the measuring element 2 is not less than the weight of the measuring element 2. This results in the water level change in the water collection chamber 11 measured by the measuring element 2 being less than the actual water level change. Therefore, in order to reduce the impact of the weight of the measuring element 2 on the measurement accuracy of the precipitation observation device 100, the rainwater collection tank 1 needs to be pre-filled with water before using the precipitation observation device 100 to measure precipitation. The buoyancy provided by the liquid in the rainwater collection tank 1 to the measuring element 2 at the initial water level is not less than the weight of the measuring element 2. Furthermore, the staff can read the initial water level in the rainwater collection tank 1 through the height indicator 21.
[0036] When the measuring component 2 is at its initial relative height position, by stopping the bottom wall of the marking ring 43 and the top wall of the positioning component 3, the initial marking surface and the current marking surface 31 can be at the same height. At this time, the reading of the height indicator 21 at the same height as the initial marking surface is the initial water level height in the water accumulation chamber 11. As the water level in the water accumulation chamber 11 rises, the initial marking surface and the current marking surface 31 separate. The operator can calculate the difference between the readings of the height indicator 21 at the same height as the initial marking surface to determine the water level change value of the water accumulation chamber 11 within a preset time, thereby determining the precipitation in the mine area within the preset time. The initial marking component 4 makes it easier for the operator to view the initial water level height in the water accumulation chamber 11, thus reducing the difficulty of calculating the precipitation in the mine area within the preset time.
[0037] Therefore, rainwater in the mine area is collected by the rainwater collection tank 1. Then, the initial height position of the measuring element 2 in the water accumulation chamber 11 is read using the initial marker surface, and the current height position of the measuring element 2 in the water accumulation chamber 11 is read using the current marker surface 31. The difference between the two can determine the height change of the measuring element 2 in the water accumulation chamber 11, and the water level change of the water accumulation chamber 11 within a preset time can be determined. Thus, the precipitation in the mine area within the preset time can be obtained. Compared with the prior art, using the precipitation observation device 100 of this application to observe the precipitation in the mine area and analyze the correlation between mine water inflow and precipitation can reduce the calculation error during analysis, thereby effectively preventing water hazards in the mine.
[0038] like Figure 1 , Figure 2 As shown, in some embodiments of this application, the positioning component 3 includes a limiting bracket 32 and a limiting ring 33. The limiting bracket 32 extends radially along the rain collection tank 1, and one end of the limiting bracket 32 is fixedly connected to the inner peripheral wall of the rain collection tank 1. The inner peripheral wall of the rain collection tank 1 is provided with an installation groove, and the limiting bracket 32 is inserted into the installation groove so that the limiting bracket 32 and the rain collection tank 1 are engaged.
[0039] The limiting ring 33 is located at the other end of the limiting bracket 32. The rain collection tank 1 can provide support to the limiting ring 33 through the limiting bracket 32 to limit the movement of the limiting ring 33 relative to the rain collection tank 1. The limiting ring 33 is sleeved on the outer periphery of the measuring member 2. The inner peripheral wall of the limiting ring 33 abuts against the outer peripheral wall of the measuring member 2. The limiting ring 33 and the measuring member 2 are radially limited and matched. When the limiting ring 33 is limited to a preset position in the rain collection tank 1 by the limiting bracket 32, the limiting ring 33 can further limit the shaking of the measuring member 2 along the radial direction of the rain collection tank 1.
[0040] Furthermore, the top wall of the limiting ring 33 is configured as the current marking surface 31. In some specific embodiments, the top wall of the limiting ring 33 extends outside the rain collection tank 1, or the top wall of the limiting ring 33 is flush with the top wall of the rain collection tank 1. Compared to the top wall of the limiting ring 33 being located inside the rain collection tank 1, this design makes it easier for staff to observe the position of the current marking surface 31 and to accurately read the height indicator 21 at the same height as the current marking surface 31.
[0041] Furthermore, such as Figure 1 , Figure 2 As shown, the positioning component 3 includes multiple limiting brackets 32, which are arranged sequentially along the circumference of the limiting ring 33. The multiple limiting brackets 32 support the limiting ring 33, thereby improving the connection strength between the limiting ring 33 and the rain collection tank 1. In some specific embodiments, such as... Figure 1 As shown, two limiting brackets 32 can be configured, with the two limiting brackets 32 evenly spaced on the outer periphery of the limiting ring 33. However, this application is not limited to this; for example, three, four, or more limiting brackets 32 can also be configured. A first guide structure 34 can be provided at the end of the limiting bracket 32 near the limiting ring 33, and a second guide structure 35 can be correspondingly provided on the outer periphery of the limiting ring 33. The first guide structure 34 and the second guide structure 35 guide and cooperate to make the limiting ring 33 suitable for moving relative to the rain collection tank 1 radially.
[0042] By setting a first guide structure 34 and a second guide structure 35 between the limiting bracket 32 and the limiting ring 33, the limiting ring 33 can move in a limited direction along the radial direction of the rain collection tank 1, thereby making the position of the measuring element 2 in the water accumulation cavity 11 more suitable. At the same time, during the assembly of the precipitation observation device 100, the limiting bracket 32 can first move towards the direction closer to the limiting ring 33, so that the limiting bracket 32 can more easily extend into the rain collection tank 1 from the opening of the water accumulation cavity 11. Then the limiting bracket 32 can move away from the limiting ring 33, so that the limiting bracket 32 can be more easily inserted into the mounting groove.
[0043] Specifically, such as Figure 2 As shown, one of the first guide structure 34 and the second guide structure 35 is a guide rod, and the other of the first guide structure 34 and the second guide structure 35 is a guide hole. For example, the first guide structure 34 is constructed as a guide rod and the second guide structure 35 is constructed as a guide hole, or the second guide structure 35 is constructed as a guide rod and the first guide structure 34 is constructed as a guide hole. The guide rod extends radially along the rain collection tank 1 and is inserted into the guide hole. By moving the guide rod along the guide hole, the technical effect of the limiting ring 33 moving radially relative to the rain collection tank 1 can be achieved.
[0044] Furthermore, a stop 37 is provided at the free end of the guide rod (i.e., the end of the guide rod inserted into the guide hole). The stop 37 is adapted to abut against the side wall of the guide hole, and the stop 37 is used to restrict the guide rod from coming out of the guide hole, thereby preventing the limiting bracket 32 and the limiting ring 33 from separating from each other. Further, as... Figure 2 As shown, an elastic element 36 that can be elastically deformable can be provided on the outer periphery of the guide rod. The elastic element 36 can be a helical spring. The elastic element 36 is used to drive the limiting ring 33 and the limiting bracket 32 to move closer or further apart. It should be noted that when there are multiple limiting brackets 32, the helical spring between each limiting bracket 32 and the limiting ring 33 is in the same initial state. The initial state of the helical spring includes tension, compression, or maintaining its original length.
[0045] When the limiting ring 33 moves toward the inner wall of the rain collection tank 1, part of the helical spring is compressed and the other part is stretched. The resultant force of the elastic force on the limiting ring 33 is opposite to the direction of movement of the limiting ring 33. The elastic element 36 can make the limiting ring 33 return to its initial position. Thus, when the precipitation monitoring device 100 is placed in different locations in the mine area, it can ensure that the limiting ring 33 remains in its initial position. At the same time, the elastic force provided by the elastic element 36 to the limiting bracket 32 can prevent the limiting bracket 32 from falling out of the mounting groove, thereby improving the working reliability of the precipitation monitoring device 100.
[0046] like Figure 1 As shown, in some embodiments of this application, the cross-section of the guide rod is polygonal, for example... Figure 1 The cross-section of the guide rod is square, and the cross-section of the guide rod is perpendicular to the axial direction of the guide rod. When the guide rod is inserted into the guide hole, by setting the cross-section of the guide rod to be polygonal, compared with setting the cross-section of the guide rod to be circular, this setting can restrict the rotation of the guide rod in the guide hole, and prevent the limiting ring 33 from causing the measuring element 2 to swing in the water accumulation chamber 11, thereby improving the measurement accuracy of the precipitation observation device 100.
[0047] like Figure 3 As shown, in some embodiments of this application, the initial marking component 4 further includes an elastic ring 41 and a pull rod 42. The elastic ring 41 is elastically sleeved on the outer periphery of the measuring member 2. The elastic ring 41 can be a rubber ring with good elasticity. By using the elastic force of the elastic ring 41 to press the elastic ring 41 against the outer periphery of the measuring member 2, the initial marking component 4 can be fixed to the outer periphery of the measuring member 2 by the elastic force of the elastic ring 41.
[0048] The marking ring 43 is located below the elastic ring 41. The marking ring 43 can be a rigid component, which ensures that the shape of the marking ring 43 does not change, and thus the shape of the initial marking surface does not change, thereby improving the measurement accuracy of the precipitation observation device 100.
[0049] A pull rod 42 connects the elastic ring 41 and the marking ring 43. The pull rod 42 also drives the elastic ring 41 to expand elastically along the radial direction of the measuring element 2. That is, the pull rod 42 can be used as a connector between the elastic ring 41 and the marking ring 43. When the operator drives the pull rod 42 to pull the elastic ring 41 radially outward along the measuring element 2, the elastic ring 41 undergoes elastic deformation and separates from the outer peripheral wall of the measuring element 2. This allows the operator to adjust the relative position between the initial marking component 4 and the measuring element 2, so that the initial marking component 4 can accurately record the initial water level height in the water accumulation chamber 11. After the relative position between the initial marking component 4 and the measuring element 2 is adjusted, the operator no longer drives the pull rod 42 to pull the elastic ring 41. The elastic ring 41 recovers its deformation and presses against the outer peripheral wall of the measuring element 2 again, thus fixing the initial marking component 4 to the outer peripheral side of the measuring element 2.
[0050] like Figure 2 , Figure 4 As shown, in some embodiments of this application, the measuring element 2 includes a measuring element body 22 and a suspension element 23. The measuring element body 22 extends along the height direction of the rainwater collection tank 1, and a height indicator mark 21 is provided on the outer peripheral wall of the measuring element body 22. A cavity 24 is formed inside the measuring element body 22, and the suspension element 23 is disposed on the bottom wall of the measuring element body 22. By providing a cavity 24 inside the measuring element 2, the average density of the measuring element 2 can be reduced, making it easier for the measuring element 2 to suspend on the rainwater collected in the water collection chamber 11.
[0051] The suspending element 23 can be made of a lightweight material, such as polyethylene or foamed polypropylene. Furthermore, the outer diameter of the suspending element 23 is larger than that of the measuring element body 22. The suspending element 23 increases the contact area between the bottom wall of the measuring element 2 and the water in the water accumulation chamber 11, making it easier for the measuring element 2 to float on the water. In addition, this arrangement improves the stability of the suspending element 23 and prevents it from tipping over.
[0052] Furthermore, the measuring component body 22 is constructed as a transparent component. In this case, the measuring component body 22 can be made of plastic, glass, or resin. The measuring component body 22 is translucent, and, as... Figure 4 , Figure 5As shown, the inner wall of cavity 24 is provided with fluorescent strips 26. When staff use the precipitation observation device 100 to collect precipitation data at night, the fluorescent strips 26 can maintain their luminescence for a period of time after absorbing light. The fluorescent strips 26 can illuminate the altitude indicator 21, making it easier for staff to read the reading of the altitude indicator 21 at the same height as the current marker surface 31. Furthermore, multiple fluorescent strips 26 can be provided, with multiple fluorescent strips 26 spaced apart along the circumference of the measuring element body 22 on the inner wall of the measuring element body 22. This can increase the fluorescence coverage of the measuring element body 22, making the altitude indicator 21 clearer.
[0053] Furthermore, such as Figure 4 , Figure 5 As shown, a slot 25 is formed within the measuring element body 22. The slot 25 is formed on the inner wall of the cavity 24 and extends along the height direction of the measuring element 2. The fluorescent strip 26 is inserted into the slot 25. The slot 25 allows the fluorescent strip 26 to adhere to the inner wall of the cavity 24 without the aid of fasteners or adhesives, thereby reducing the installation difficulty of the fluorescent strip 26. In some preferred embodiments, the measuring element body 22 can be a measuring cylinder with a cavity 24 and graduations on its outer peripheral wall. Using a measuring cylinder as the measuring element body 22 can reduce the production cost of the precipitation observation device 100. It should be noted that when using a measuring cylinder as the measuring element body 22, in order to prevent rainwater from entering the cavity 24 and affecting the measurement accuracy of the measuring element 2, the top opening of the measuring cylinder needs to be sealed with a rubber stopper or other sealing material.
[0054] like Figure 1 , Figure 2 As shown, in some embodiments of this application, the bottom wall of the rain collection tank 1 may be provided with multiple support legs 5, which are arranged sequentially and at intervals along the circumference of the rain collection tank 1. The rain collection tank 1 can be supported on the ground by the support legs 5. The support legs 5 enable the rain collection tank 1 to adapt to the ground surface of the mine area, preventing the gravel on the mine surface from affecting the stability of the rain collection tank 1. This can prevent the rain collection tank 1 from shaking and affecting the actual water level in the water accumulation chamber 11, thereby further improving the accuracy of the precipitation measurement device 100 in obtaining precipitation data.
[0055] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
