Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of rubber dam measurement, and in particular to a rubber dam height measurement device and a rubber dam control method. Background Art

[0002] Cascade rubber dams are usually used to intercept surface runoff and increase the utilization of river water resources. As a new type of water conservancy structure, rubber dams have little experience in corresponding flow monitoring, especially in terms of low-head and high-precision flow measurement on the dam. There are currently problems such as immature flow measurement technology, relatively single flow measurement methods, and lack of flow measurement instruments that are highly compatible with it. At present, when monitoring the flow of rubber dams, the commonly used method is to use radar ultrasonic waves to measure the surface flow velocity or determine the flow velocity through the time difference method, and then control the rise or fall of the rubber dam.

[0003] However, when the above method is used to monitor the flow of rubber dams, the following technical problems often occur:

[0004] The measurement of surface flow velocity is easily disturbed by wind speed, resulting in a larger measured flow velocity, causing the control rubber dam to rise a larger distance, which in turn leads to a smaller or even disappearing downstream water flow. When the flow velocity is determined by the time difference method, it is difficult to determine the installation position of the ultrasonic radar because the rubber dam needs to be raised and lowered, and thus the water flow velocity cannot be determined. In addition, the backwater in front of the dam pier is seriously affected by the water retaining effect of the dam body, which interferes with the flow velocity measurement.

Specifically, the reasons for the small or even disappearance of the downstream water flow and the inability to determine the water flow velocity are: the surface flow velocity is easily disturbed by the wind speed, resulting in the measured flow velocity being too large, causing the control rubber dam to rise too far, which in turn causes the downstream water flow to be small or even disappear. When determining the flow velocity by the time difference method, since the rubber dam needs to be raised and lowered, it is difficult to determine the installation position of the ultrasonic radar, and thus the water flow velocity cannot be determined. In addition, the water backflow in front of the dam pier is seriously affected by the water retaining of the dam body, which interferes with the flow velocity measurement.

Also, by measuring the coordination between the vertical rod and the horizontal rod, the current height of the rubber dam can be accurately determined, and thus the water flow rate can be accurately determined. The height of the rubber dam can be adjusted according to the water flow rate, avoiding the situation where the downstream water flow is small or even disappears, and avoiding the situation where the water flow rate cannot be determined.

[0038] Continue to refer Figure 4 , shows a process 400 of some embodiments of the rubber dam control method according to the present disclosure. The rubber dam control method is applied to Figure 1 The rubber dam height measuring device shown comprises the following steps:

[0039] Step 401, obtaining water weir parameter information.

[0040] In some embodiments, the execution body (such as a computing device) of the rubber dam control method can obtain water weir parameter information from the target database through a wired connection or a wireless connection. Among them, the above-mentioned water weir parameter information includes section width, water flow coefficient, flooding coefficient, weir flow side contraction coefficient and bank slope height. The above-mentioned section width can be the width of the cross section of the water weir. The above-mentioned water flow coefficient can be the flow coefficient of the water weir. The above-mentioned flooding coefficient can be the head loss coefficient caused by the flooding of water flow when the water flows through the gate hole. Here, there is no restriction on the setting of the flooding coefficient, and it can be a coefficient obtained through experiments on the wide-top weir part. The above-mentioned bank slope height can be the height from the bank slope to the bottom plate.

[0041] Step 402, controlling the water level monitoring device to measure the water level depth, and controlling the inclinometer to collect and measure the rotation angle of the vertical rod.

[0042] In some embodiments, the execution entity may control the water level monitoring device to measure the water level depth, and control the inclinometer to collect the rotation angle of the measuring vertical rod.

[0043] Step 403, determining the height of the rubber dam according to the height of the bank slope, the length of the vertical rod and the rotation angle.

[0044] In practice, the height of the rubber dam can be determined by the following steps:

[0045] The first step is to determine the distance between the installation position of the rotatable fixture and the top of the slope as the fixture distance.

[0046] In the second step, the difference between the bank slope height and the distance from the fixing device is determined as the fixing device height.

[0047] The third step is to determine the product of the length of the measuring vertical rod and the rotation angle as the height of the dam top fixing device.

[0048] The fourth step is to determine the difference between the height of the above-mentioned fixing device and the height of the above-mentioned dam top fixing device as the height of the rubber dam.

[0049] Step 404, determining the water head height according to the water level depth and the rubber dam height.

[0050] In some embodiments, the execution body may determine the water head height according to the water level depth and the rubber dam height. In practice, the difference between the water level depth and the rubber dam height may be determined as the water head height.

[0051] Step 405: Control the flow rate sensor included in the sensor group to determine the flow rate at the crest of the rubber dam.

[0052] In some embodiments, the execution subject may control the flow velocity sensor included in the sensor group to determine the flow velocity at the top of the rubber dam. In practice, the execution subject may control the flow velocity sensor included in the sensor group in real time to determine the flow velocity at the top of the rubber dam.

[0053] Step 406, determining the flow rate of the water weir passing through the dam according to the dam top flow velocity, water head height, section width, water flow coefficient, flooding coefficient and weir flow side contraction coefficient.

[0054] In some embodiments, the water weir flow rate can be determined according to the dam top flow velocity, the water head height, the cross-sectional width, the water flow coefficient, the submergence coefficient and the weir flow side contraction coefficient. In practice, the water weir flow rate can be determined by the following formula:

[0055]

[0056] Among them, Q is the flow rate of the water weir. ε is the contraction coefficient of the weir flow side. σ is the flooding coefficient. m is the flow coefficient. B is the section width. h0 is the head height. g is the flow velocity at the dam top.

[0057] Step 407, controlling the rubber dam to perform lifting operations according to the water weir flow rate.

[0058] In some embodiments, the execution body can control the rubber dam to perform lifting and lowering operations according to the water weir flow rate. In practice, in response to the water weir flow rate being greater than or equal to a preset flow rate threshold, the execution body can control the rubber dam to rise. In response to the water weir flow rate being less than the preset flow rate threshold, the rubber dam can be controlled to descend.

[0059] In the process of adopting technical solutions to solve the above technical problems, the following problems often occur: During the operation of the rubber dam, the rubber dam will be affected by environmental factors, resulting in a reduced lifespan, which in turn leads to a decrease in the ability of the rubber dam to intercept water flow, and lower safety for downstream personnel. In response to these problems, the conventional solution is generally to adjust the rubber dam to a fixed height at a fixed time to reduce the impact of environmental factors on the rubber dam. The inventor took into account the disadvantage that when the rubber dam is adjusted to a fixed height at a fixed time, the rubber dam cannot intercept the water flow in time during the flood season, resulting in lower safety for downstream personnel. In combination with the advantages of the inventor's company, we decided to adopt the following solution.

[0060] In some optional implementations of some embodiments, the rubber dam may be controlled to perform a lifting operation through the following steps:

[0061] The first step is to obtain the rubber dam environmental information corresponding to the rubber dam and the corresponding relationship table between the water weir flow rate and the rubber dam height range. The rubber dam environmental information may include but is not limited to: temperature information, ultraviolet intensity information, sediment accumulation information, and altitude information. The corresponding relationship table may be a corresponding relationship table between the water weir flow rate and the rubber dam height range obtained through experiments, which is used to indicate that when the water weir flow rate is at a certain value, the height of the rubber dam should be controlled within a certain range.

[0062] The second step is to select the rubber dam height range corresponding to the water weir over-dam flow rate from the above correspondence table as the target height range according to the water weir over-dam flow rate. In practice, the water weir over-dam flow rate that is the same as the water weir over-dam flow rate can be selected from the above correspondence table as the target water weir over-dam flow rate, and the rubber dam height range corresponding to the target water weir over-dam flow rate is determined as the target height range.

[0063] The third step is to select the temperature information and ultraviolet intensity information corresponding to the rubber dam from the rubber dam environmental information.

[0064] The fourth step is to determine the upstream flow velocity and downstream flow velocity corresponding to the rubber dam according to the preset radar ultrasonic device group. The preset radar ultrasonic device group includes at least two preset radar ultrasonic devices, which are respectively installed upstream and downstream of the rubber dam to detect the surface water flow velocity upstream and downstream.

[0065] The fifth step is to determine the environmental factor value according to the temperature information, the ultraviolet intensity information, the upstream flow velocity and the downstream flow velocity. In practice, first, the temperature information, the ultraviolet intensity information, the upstream flow velocity and the downstream flow velocity can be normalized to obtain normalized temperature information, normalized ultraviolet intensity information, normalized upstream flow velocity and normalized downstream flow velocity. Second, the product of the normalized temperature information and the first weight, the product of the normalized ultraviolet intensity information and the second weight, the product of the normalized upstream flow velocity and the normalized third weight, and the sum of the downstream flow velocity and the fourth weight can be used as the environmental value, and the ratio of the environmental value to the sum of the normalized temperature information, the normalized ultraviolet intensity information, the normalized upstream flow velocity and the normalized downstream flow velocity is determined as the environmental factor information. Here, there is no restriction on the setting of each weight, which can be a weight obtained through experiments.

[0066] Step 6: According to the above environmental factor values, perform the following correction steps:

[0067] The first correction step is to obtain a set of historical water consumption information of downstream users, wherein the set of historical water consumption information of downstream users in the set is the water consumption of each downstream user within a preset range on a certain day in a historical time period.

[0068] The second correction step is to determine the sequence of the total historical water consumption of the downstream users for each of the historical water consumption information groups of the downstream users in the historical water consumption information group set. In practice, for each of the historical water consumption information groups of the downstream users, the sum of the total historical water consumption of each of the downstream users in the historical water consumption information group of the downstream users can be determined as the total historical water consumption of the downstream users, and the obtained total historical water consumption of each of the downstream users can be sorted in the order of the corresponding dates.

[0069] The third correction step is to determine the daily water consumption of the downstream users according to the historical total water consumption of each downstream user included in the above-mentioned historical total water consumption sequence of the downstream users. In practice, the average of the historical total water consumption of each downstream user included in the above-mentioned historical total water consumption sequence of the downstream users can be determined as the daily water consumption of the downstream users.

[0070] The fourth calibration step is to determine whether the current time meets the preset flood season condition, wherein the preset flood season condition may be whether the current time is within the flood season.

[0071] The fifth correction step is to generate a flood season adjustment value in response to the current time satisfying the preset flood season condition. The flood season adjustment value may be a preset value. For example, the flood season adjustment value may be 1.

[0072] The sixth correction step is to correct the environmental factor value according to the daily water consumption of the downstream user and the flood season adjustment value to obtain the corrected environmental factor value.

[0073] Step 7: According to the environmental factor value, a target height that meets the second preset condition is selected from the target height range as the height adjustment value. In practice, the height adjustment value can be determined by multiplying the difference between the maximum and minimum values ​​of the target height range by the environmental factor value.

[0074] In the eighth step, the rubber dam is controlled to perform lifting operations according to the height of the rubber dam and the height adjustment value.

[0075] The above-mentioned first step to the eighth step, as an inventive point of an embodiment of the present disclosure, solves the technical problem mentioned in the background technology that "during the operation of the rubber dam, the rubber dam will be affected by environmental factors, resulting in a reduction in its lifespan, which in turn leads to a decrease in the ability of the rubber dam to intercept water flow, and the safety of downstream personnel is relatively low". The reasons for the low safety of downstream personnel are as follows: during the operation of the rubber dam, the rubber dam will be affected by environmental factors, resulting in a reduction in its lifespan, which in turn leads to a decrease in the ability of the rubber dam to intercept water flow, and the safety of downstream personnel is relatively low. If the above-mentioned factors are solved, the effect of improving the safety of downstream personnel can be achieved. In order to achieve this effect, the present disclosure first obtains the rubber dam environmental information corresponding to the above-mentioned rubber dam and the correspondence table between the water weir over-dam flow and the rubber dam height range. In this way, the surrounding environment of the rubber dam can be determined in real time. Second, according to the above-mentioned water weir over-dam flow, the rubber dam height range corresponding to the above-mentioned water weir over-dam flow is selected from the above-mentioned correspondence table as the target height range. In this way, the range in which the rubber dam can be adjusted can be determined. Third, the temperature information and ultraviolet intensity information corresponding to the rubber dam are selected from the rubber dam environmental information; the upstream flow velocity and downstream flow velocity corresponding to the rubber dam are determined according to the preset radar ultrasonic equipment group; the environmental factor value is determined according to the temperature information, the ultraviolet intensity information, the upstream flow velocity and the downstream flow velocity. Thus, the adjustment value of the environment for the rubber dam can be determined. Fourth, according to the environmental factor value, the following correction steps are performed: the downstream user historical water use information group set is obtained; for each downstream user historical water use information group in the downstream user historical water use information group set, the downstream user historical total water use sequence is determined. Thus, the total water use of the downstream user per day in the historical time period can be determined. Fifth, according to the historical total water use of each downstream user included in the downstream user historical total water use sequence, the downstream user's daily water use is determined; it is determined whether the current time meets the preset flood season condition; in response to the current time meeting the preset flood season condition, a flood season adjustment value is generated; according to the downstream user's daily water use and the flood season adjustment value, the environmental factor value is corrected to obtain the corrected environmental factor value. Thus, the environmental factor value can be corrected by the daily average water consumption of downstream users and the flood season, thereby avoiding the situation where the water flow is too small or even dried up due to the high adjustment of the rubber dam height, or the water flow is large during the flood season due to the low adjustment of the rubber dam height, which affects the safety of downstream personnel. Sixth, according to the corrected environmental factor value, the target height that meets the second preset condition is selected from the target height range as the height adjustment value. Thus, a more accurate rubber dam height adjustment value is selected. Seventh, according to the rubber dam height and the height adjustment value, the rubber dam is controlled to perform lifting and lowering operations. Thus, the safety of downstream personnel is improved by real-time collection of the rubber dam environment, and by adjusting the height of the rubber dam according to the water consumption of downstream personnel and flood season factors.

[0076] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the rubber dam control method of some embodiments of the present disclosure, the downstream water flow is prevented from being small or even disappearing, and the water flow velocity cannot be determined. Specifically, the reason for the small or even disappearance of the downstream water flow, or the inability to determine the water flow velocity, is that the measured surface flow velocity is easily disturbed by the wind speed, resulting in a large measured flow velocity, causing the control rubber dam to rise a large distance, which in turn causes the downstream water flow to be small or even disappear. When the flow velocity is determined by the time difference method, it is difficult to determine the installation position of the ultrasonic radar because the rubber dam needs to be raised and lowered, and the water flow velocity cannot be determined. In addition, the backwater in front of the dam pier is seriously affected by the water retaining of the dam body, which interferes with the flow velocity measurement. Based on this, the rubber dam control method of some embodiments of the present disclosure, first, obtains the water weir parameter information. Thus, the parameter information of the water weir can be determined. Secondly, the water level monitoring equipment is controlled to measure the water level depth, and the angle meter is controlled to collect the rotation angle of the measuring vertical rod. Thus, the water level depth and the degree of rotation of the measuring vertical rod caused by the current rubber dam height can be determined. Then, the height of the rubber dam is determined according to the bank slope height, the length of the measuring vertical rod and the rotation angle. Thus, the current height of the rubber dam can be determined. After that, the head height is determined according to the water level depth and the height of the rubber dam; the flow rate sensor included in the sensor group is controlled to determine the dam top flow rate of the rubber dam. Thus, the parameters required for measuring the water flow can be determined. Then, the water weir over-dam flow is determined according to the dam top flow rate, the head height, the cross-sectional width, the water flow coefficient, the flooding coefficient and the weir flow side contraction coefficient. Thus, the water weir over-dam flow can be determined. Finally, according to the water weir over-dam flow, the rubber dam is controlled to perform lifting and lowering operations. Thus, the height of the rubber dam can be regulated by the size of the water weir over-dam flow, thereby avoiding the downstream water flow being small or even disappearing, and avoiding the inability to determine the water flow rate.
