Description

Technical Field

[0001] The present invention relates to a water retaining device, in particular to a water retaining device for water conservancy project construction applied in the field of water conservancy projects. Background Art

[0002] Water conservancy projects refer to a series of facilities and structures built to control, regulate and utilize water resources. These projects are not only crucial to flood prevention and disaster reduction, but also related to agricultural irrigation, urban water supply, industrial water use and many other aspects. They are an important foundation for the development of human society. Among the devices built as water conservancy flood control projects to prevent and reduce flood disasters, water retaining devices are mainly used to intercept or regulate water flow, and are generally coordinated with buildings such as dams or levees to protect the safety of downstream areas.

[0003] The specification of Chinese invention patent CN114808843A discloses a water retaining device for water conservancy project construction, which belongs to the technical field of water conservancy projects and is used to solve the problems that the prior art cannot buffer, release and utilize the impact force of water waves, and it is difficult to effectively support the water retaining plate and ensure that the water retaining plate can continuously and stably retain water. Specifically, it is a water retaining device for water conservancy project construction, including a main baffle, a buffer protection seat is installed on the water-facing surface of the main baffle, an anti-impact seat is provided on the buffer protection seat, and multiple groups of buffer conversion mechanisms are installed on the anti-impact seat, a lower plug-in locking mechanism is installed on the back surface of the main baffle, and the lower plug-in locking mechanism is inserted into the ground, an inclinedly supported reinforced correction electric push rod is installed on the back surface of the main baffle, and an auxiliary adjustable baffle inserted into the inside is installed on the main baffle; the present invention effectively fixes the main baffle by the lower plug-in locking mechanism and the reinforced correction electric push rod, and can effectively buffer and utilize the impact force of water flow, which is conducive to the continuous and stable water retaining of the main baffle.

[0004] In flood control applications of water conservancy projects, similar devices in the above-mentioned water retaining devices usually rely on electric push rods to drive the supporting water retaining plates to flip and stand up, so as to cooperate with buildings such as dams or dikes to effectively intercept and regulate the water flow. Although the setting of the buffer conversion mechanism can alleviate the impact of the water flow to a certain extent and ensure the effectiveness of the water retaining device, these devices lack the ability to monitor the status of the water retaining plates in real time during operation.

[0021] It should be noted that the air pump mechanism is a mechanical structure in the prior art, which is directly quoted here without any changes to its principle and structure. Those skilled in the art can select and match it according to actual needs, and can transport and regulate air to achieve the deformation control of the regulating air bag 5. For example, the air pump mechanism includes a blower, a main conveying pipeline and a branch conveying pipeline. The output end of the blower is fixedly connected to the main conveying pipeline, the other end of the main conveying pipeline is fixedly connected to the branch conveying pipeline, and the other end of the branch conveying pipeline is fixedly connected to the diversion pipe group, which can be pneumatically regulated by water blocking. The unit controls the operation of the blower to deliver air to the diverter pipe group embedded in the dam body 1 through the main delivery pipe and the branch delivery pipe, and then controls the stop valve arranged on the air circuit branch pipe 51 through the water retaining pneumatic control unit to regulate the air in the diverter pipe group to be delivered through the air circuit branch pipe 51 to the regulating air bag 5 that needs to be regulated, thereby driving the regulating air bag 5 to produce elongation deformation. When it is necessary to produce deformation recovery effect on the regulating air bag 5, the air in the regulating air bag 5 can be released by regulating the pressure relief valve on the air circuit branch pipe 51, causing the regulating air bag 5 to produce deformation recovery effect.

[0022] Figure 1 , Figure 3 , Figure 4 and Figure 6 - Figure 8 It is shown that a plurality of electric push rods 12 are hingedly connected to the middle part of the rear end of the water retaining plate 2, and the rear end of the electric push rod 12 is hingedly installed on the dam body 1, and a vertical groove 21 is fixedly connected to the lower side of the rear end of the water retaining plate 2, and a rotating shaft 11 is rotatably connected in the vertical groove 21, and the lower end of the rotating shaft 11 is fixedly installed on the dam body 1, and the output end of the intelligent water retaining treatment unit is also connected to a support adjustment unit, and the output end of the support adjustment unit is connected to the electric push rod 12 signal, and the electric push rod 12 can effectively support the water retaining plate 2 to ensure its blocking effect on the water flow, and cooperate with the setting of the support adjustment unit to realize the automatic regulation of the electric push rod 12, and effectively dynamically adjust the water retaining angle of the water retaining plate 2, thereby ensuring the water retaining and flood prevention effect of the water retaining plate 2 while reducing the stress damage of the water retaining plate 2 caused by the continuous impact of the water flow on one position, thereby promoting its durability during the flood prevention effect.

[0023] Figure 4 - Fig.12It is shown that the rear inner wall of the buffer adjustment chamber 31 is fixedly connected with an elastic cone strip 61, the front end of the elastic cone strip 61 is fixedly connected with a pomegranate-shaped elastic bag 62, and the front end of the pomegranate-shaped elastic bag 62 is open, the front inner wall of the buffer adjustment chamber 31 is fixedly connected with a support rod 63 at a position corresponding to the pomegranate-shaped elastic bag 62, the rear end of the support rod 63 is fixedly connected with a warning trigger ball 64, and the warning trigger ball 64 is in sliding cooperation with the pomegranate-shaped elastic bag 62, the pomegranate-shaped elastic bag 62 wraps the warning trigger ball 64, and passes through the opening at the front end of the pomegranate-shaped elastic bag 62 The warning trigger ball 64 can be shaped to slide out and enter. The buffer strip 3, the elastic connecting plate 4, the regulating air bag 5, the elastic cone strip 61 and the pomegranate-shaped elastic bag 62 are all made of elastic composite materials. The cooperation of the pomegranate-shaped elastic bag 62 and the warning trigger ball 64 can effectively display the shape of the buffer strip 3, and then when it performs the flood prevention function, it can generate status feedback, and then when the buffer strip 3 is damaged abnormally, it can be maintained and repaired in time to avoid water leakage that endangers the safety of downstream areas.

[0024] Fig. 9 - Fig.12 It is shown that a contraction contact block is embedded in the front end of the warning trigger ball 64, and a plurality of extension contact blocks are fixedly connected to the rear end of the warning trigger ball 64. A bottoming arc piece matching the contraction contact block is fixedly connected to the rear inner wall of the pomegranate-shaped elastic bag 62, and a plurality of mouth arc pieces matching the extension contact blocks are fixedly connected to the front inner wall of the pomegranate-shaped elastic bag 62. The cooperation of the contraction contact block and the extension contact block can effectively display data on the position of the warning trigger ball 64 in the pomegranate-shaped elastic bag 62. When the warning trigger ball 64 and the pomegranate-shaped elastic bag 62 produce deformation movements along with the buffer strip 3, data feedback can be sent to the intelligent water retaining processing unit in time, so that the intelligent water retaining control system can timely judge the state of the buffer strip 3, and can timely judge the damage of the buffer strip 3 and give a warning to it, thereby ensuring the continuous effectiveness of the flood control function of the water retaining plate 2.

[0025] Figure 2It is shown that the warning trigger feedback unit includes a contraction trigger warning module, an extension trigger warning module and a double disconnection trigger warning module. The contraction trigger warning module, the extension trigger warning module and the double disconnection trigger warning module are arranged in parallel. The input end of the contraction trigger warning module is connected to the contraction contact block signal, the output end of the extension trigger warning module is connected to the extension contact block signal, and the input end of the double disconnection trigger warning module is respectively connected to the contraction contact block and the extension contact block signal. The setting of the contraction trigger warning module, the extension trigger warning module and the double disconnection trigger warning module can effectively realize the recognition and transmission of the data displayed by the warning trigger component 6, and assist the intelligent water retaining processing unit to quickly judge the state of the buffer bar 3. While reducing the data processing burden of the intelligent water retaining processing unit, it can be quickly judged and processed when an abnormality occurs in the buffer bar 3, effectively buying time for the subsequent maintenance of the water retaining plate 2 and the buffer bar 3, ensuring the effectiveness of the flood control function, and improving the flood control effect of the water retaining plate 2 and the buffer bar 3.

[0026] Fig. 9 - Fig.12 It shows that the stiffness coefficient of the elastic cone strip 61 is smaller than the stiffness coefficient of the pomegranate-shaped elastic bag 62. When the warning trigger ball 64 moves to the right end portion of the pomegranate-shaped elastic bag 62, the elastic cone strip 61 and the pomegranate-shaped elastic bag 62 will be stretched and deformed first, and then the pomegranate-shaped elastic bag 62 will be deformed so that the warning trigger ball 64 can be separated from the pomegranate-shaped elastic bag 62, thereby maintaining the constant triggering of the elongated contact block in the early stage, so that the elastic cone strip 61 can be stretched and deformed before the pomegranate-shaped elastic bag 62, and an effective triggering time can be reserved for the elongated contact block, thereby making the deformation change of the warning trigger ball 64 in the pomegranate-shaped elastic bag 62 effectively suitable for the functionality of the buffer strip 3, thereby improving the effectiveness and accuracy of data transmission by the warning trigger component 6.

[0027] Figure 1 - Figure 3 It is shown that the input end of the intelligent water retaining treatment unit is also connected to a warning data verification unit, and the input end of the warning data verification unit is connected to the pressure probe signal arranged in the regulating air bag 5. The setting of the warning data verification unit can further promote the validity of the data for judging the state of the buffer strip 3 and the warning, avoid the problem of unnoticed damage to the buffer strip 3, and thus fully ensure the flood control effectiveness of the water retaining plate 2 and the buffer strip 3, and promote the effectiveness of safety protection in the downstream area.

[0028] Figure 4 and Figure 7It is shown that a plurality of elastic support strips 32 are fixedly connected between the front and rear inner walls of the buffer adjustment chamber 31, and the elastic support strips 32 remain in a contracted state when not acted upon by external force, and the plurality of elastic support strips 32 are all arranged between the two warning trigger components 6, and the stiffness coefficient of the elastic support strips 32 is greater than the stiffness coefficient of the elastic cone strip 61, and the plurality of elastic support strips 32 are arranged in the middle position of the buffer adjustment chamber 31, and the elastic support strips 32 in the contracted state still retain a certain contraction margin, and can continue to contract when under pressure, and the deformation direction of the elastic support strips 32 is the front-to-back direction, that is, perpendicular to the direction of the water retaining surface of the buffer strip 3, and the elastic recovery effect of the buffer strip 3 can be maintained by the setting of the elastic support strip 32, while promoting its buffering effect on the impact force of the water flow, it can also effectively assist the adjustment air bag 5 to produce a deflation effect, thereby facilitating the regulation of the water retaining surface of the buffer strip 3.

[0029] Figure 1 - Fig.12 It is shown that when the water retaining device is installed and applied on the dam body 1, the front end of the water retaining plate 2 and the buffer strip 3 is the water retaining surface, that is, the water flow that needs to be acted on is at the front end, and the rear end of the water retaining plate 2 is the downstream area. The water conservancy maintenance personnel set the relevant data about water retaining in the water conservancy program setting unit through the water conservancy project maintenance platform. These data include but are not limited to support angle data, air pressure control data of the air bag 5 during flood control, air pressure control data of the air bag 5 during drainage, air pressure control data of the air bag 5 during water retaining, and judgment basis of the triggering data state of the warning trigger component 6. The water conservancy program setting unit converts these data and transmits them to the intelligent water retaining processing unit. When selecting functions, the water conservancy maintenance personnel can send control instructions to the intelligent water retaining processing unit through the water conservancy project maintenance platform through the water conservancy program setting unit, so that the intelligent water retaining processing unit can act on the support control unit and the water retaining pneumatic control unit according to the control instructions to ensure the effectiveness of the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4.

[0030] During the normal water blocking effect, the intelligent water blocking processing unit will send a control instruction to the support and control unit, so that the support and control unit controls the electric push rod 12 to produce an extension action, so that the water baffle 2 produces a forward reversal action under the rotation limit of the vertical groove 21 and the rotating shaft 11, and the electric push rod 12 is made into the water baffle 2 to maintain the water blocking effect state. At this time, the buffer strip 3 maintains a continuous contraction state under the elastic support and isolation of the elastic support strip 32, and under the elastic contraction of the elastic support strip 32, the distance between the front and rear inner walls of the buffer adjustment chamber 31 is the minimum value, so the warning trigger component 6 should maintain a contraction trigger state, that is, the warning trigger ball 64 is in the pomegranate-shaped elastic bag 62 and is located at the rear inner wall of the pomegranate-shaped elastic bag 62, so that the contraction contact block is in contact with the bottoming arc sheet of the rear inner wall of the pomegranate-shaped elastic bag 62, and the contraction trigger warning module in the warning trigger feedback unit is turned on, and the contraction trigger signal is transmitted to the intelligent water blocking processing unit, so that the intelligent water blocking processing unit can judge the state validity of the buffer strip 3 according to the contraction trigger signal at this time; After receiving all the contraction trigger data, it indicates that the buffer strip 3 is in normal state; when receiving the trigger signals of the other two modules of the warning trigger feedback unit or no signal, it is judged that the buffer strip 3 is in abnormal state at this time, and then the water retaining pneumatic control unit is regulated, so that the water retaining pneumatic control unit controls the pressure relief valve on the air path branch pipe 51, and performs all the pressure relief actions on the regulating air bag 5, and through the effect of deflating the regulating air bag 5, the resistance of the regulating air bag 5 to the elastic contraction recovery of the elastic support strip 32 is reduced, so that the elastic support strip 32 drives the distance between the front and rear inner walls of the buffer regulating chamber 31 to continuously decrease, causing the warning trigger ball 64 and the contraction contact block and the bottoming arc piece on the pomegranate-shaped elastic bag 62 to continuously abut, and the contraction trigger warning module is turned on; when the intelligent water retaining processing unit receives the contraction trigger again, After the contraction signal of the warning module is received, it is judged that the pressure relief of the water retaining pneumatic control unit is effective, and the buffer strip 3 resumes its normal water retaining function state; when the intelligent water retaining processing unit still does not receive the contraction signal transmitted by the contraction trigger warning module, it is judged that the buffer strip 3 is damaged at this time, and then the warning unit controls the warning light at the rear end of the water retaining plate 2 on the buffer strip 3 to light up, and controls the alarm on the intelligent water retaining control box to start, which can timely issue warning reminders and light positioning to the on-site maintenance personnel. The warning unit will also transmit the warning data to the water retaining data feedback unit, so that the water retaining data feedback unit transmits the warning data to the water conservancy project maintenance platform through the remote signal transmitter, so that the water conservancy project maintenance platform can promptly check and maintain the abnormal buffer strip 3 to ensure the continued effectiveness of the subsequent effects of the buffer strip 3; When the buffer strip 3 maintains the water-retaining effect through the elastic force of the elastic support strip 32 itself, the water flow at the front end of the buffer strip 3 generates pressure on the front end of the buffer strip 3, and the buffer strip 3 can effectively buffer the pressure, thereby reducing direct damage to the water retaining plate 2. Moreover, due to the setting of the elastic connecting plate 4, the elastic connecting plate 4 and the water retaining plate 2 are not in contact, which can enable the elastic connecting plate 4 to further buffer the water flow pressure, thereby effectively improving the durability of the water retaining plate 2. Moreover, during the water-retaining effect, the intelligent water-retaining processing unit can also control the support adjustment unit to change the action length of the electric push rod 12, thereby changing the water-retaining angle of the water retaining plate 2, thereby effectively avoiding the water flow pressure from continuously acting on the same height position of the buffer strip 3 and the elastic connecting plate 4, thereby causing the problem of stress damage at this position, thereby effectively promoting the durability of the buffer strip 3 and the elastic connecting plate 4, and effectively promoting the intelligence level of the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4 during the water-retaining effect, thereby improving the water-retaining effect. And in the process of continuous water retaining effect, the intelligent water retaining processing unit will transmit all the data of its control data to the water retaining data feedback unit, so that the water conservancy project maintenance personnel can receive the effective data of the water retaining plate 2, buffer strip 3 and elastic connecting plate 4 in real time through the water conservancy project maintenance platform, thereby effectively promoting the effectiveness of the water conservancy project maintenance personnel's judgment on the status of the water retaining plate 2, buffer strip 3 and elastic connecting plate 4, and reducing the difficulty of maintenance.

[0031] When the water retaining plate 2, buffer strip 3 and elastic connecting plate 4 are in the water retaining effect and there is a sudden increase in water flow or abnormal reception of instruction data by the water conservancy program setting unit, the water conservancy project maintenance personnel can also send emergency flood control start-up data to the emergency start-up unit through the emergency button on the intelligent water retaining control box, so that the intelligent water retaining processing unit can regulate the support control unit and the water retaining pneumatic control unit according to the received data of the emergency start-up, further promoting the effectiveness of the water retaining plate 2, buffer strip 3 and elastic connecting plate 4 in the flood control effect, providing a new start-up guarantee for the flood control effect, and promoting the role of safety protection in downstream areas.

[0032] During flood prevention, the intelligent water retaining treatment unit sends a control instruction to the water retaining pneumatic control unit, so that the water retaining pneumatic control unit sends a control instruction to the air pump mechanism, and keeps the pressure relief valve on the air branch pipe 51 closed, controls the stop valve on the upper air branch pipe 51 to open, and closes the stop valve on the lower air branch pipe 51. Then the air pump mechanism transports gas to the regulating air bag 5 located on the upper side of the elastic support strip 32 through the diverter pipe group embedded in the dam body 1 and the air branch pipe 51 on the upper side, so that the regulating air bag 5 is stretched and deformed, driving the space of the buffer regulating chamber 31 to gradually form a shape that is wide at the top and narrow at the bottom, so that the water retaining surface at the upper end of the buffer strip 3 gradually forms a forward tilted state, and in the process of the buffer strip 3 tilting forward , it will synchronously drive the elastic connecting plate 4 to tilt, further releasing the gap space between the elastic connecting plate 4 and the water retaining plate 2. In the process of the shape change of the buffer adjustment chamber 31, it will also have a regulating effect on the position of the warning trigger ball 64. Due to the increase of the upper space of the buffer adjustment chamber 31, the distance between the front and rear inner walls on the upper side of the buffer adjustment chamber 31 gradually increases, and then the warning trigger component 6 on the upper side gradually changes from the contraction trigger state to the disengagement state, that is, the warning trigger ball 64 is driven to move forward through the support rod 63, and the warning trigger ball 64 is driven to move forward in the pomegranate-shaped elastic bag 62, disconnecting the contact between the contraction contact block and the bottoming arc piece, disconnecting the conduction effect of the contraction trigger warning module, and then When the pomegranate-shaped elastic bag 62 moves to the front end of the pomegranate-shaped elastic bag 62, the closing position of the pomegranate-shaped elastic bag 62 will generate resistance to movement, causing the extended contact block on the warning trigger ball 64 to abut against the arc piece at the inner wall of the pomegranate-shaped elastic bag 62, and then the elastic cone strip 61 is extended due to the resistance at the mouth of the pomegranate-shaped elastic bag 62. During the extension of the elastic cone strip 61, the pomegranate-shaped elastic bag 62 gradually deforms, and the mouth of the pomegranate-shaped elastic bag 62 continuously expands the caliber to release the warning trigger ball 64, until the warning trigger ball 64 is completely separated from the pomegranate-shaped elastic bag 62 to form a detached state. In this process, the intelligent water retaining treatment unit will first receive the contraction signal transmitted by the contraction trigger warning module due to the abutment of the contraction contact block and the bottom-touching arc piece. , and then due to the forward movement of the warning trigger ball 64 in the pomegranate-shaped elastic bag 62, the contraction contact block and the bottom arc piece are not in contact, and the extension contact block and the mouth arc piece are still not in contact, causing the double-disconnection trigger warning module to be turned on to transmit the double-disconnection signal to the intelligent water retaining processing unit, and then the warning trigger ball 64 moves to the mouth position of the pomegranate-shaped elastic bag 62, and the extension contact block and the mouth arc piece abut against each other, and the extension trigger warning module is triggered to be turned on, so that the intelligent water retaining processing unit receives the extension signal, and finally after the warning trigger ball 64 is separated from the pomegranate-shaped elastic bag 62, the extension contact block and the mouth arc piece are disconnected without contact, and the contraction contact block and the bottom arc piece remain continuously non-contacting, and the double-disconnection trigger warning module is continuously turned on to continuously transmit the double-disconnection signal to the intelligent water retaining processing unit,The intelligent water retaining processing unit can judge the effectiveness of the tilt control function of the buffer strip 3 at this time according to the received signal data change process of the upper warning trigger component 6 (contraction signal → double disconnection signal → extension signal → double disconnection signal), and the warning trigger component 6 located at the lower side will also drive the warning trigger ball 64 to move forward through the support rod 63 through the change of the inner wall of the buffer adjustment cavity 31 during the process of the buffer strip 3 tilting forward, so that the warning trigger component 6 located at the lower side of the buffer adjustment cavity 31 will gradually change from the contraction trigger state to the extension trigger state, that is, the warning trigger ball 64 gradually moves forward in the pomegranate-shaped elastic bag 62. Move, the rear end makes the contraction contact block and the bottom arc piece not contact, and then continue to move, so that the warning trigger ball 64 moves to the mouth position of the pomegranate-shaped elastic bag 62, until the extension contact block and the mouth arc piece abut. In this process, the intelligent water retaining processing unit can receive the contraction signal of the contraction trigger warning module, and then receive the double disconnection signal transmitted by the double disconnection trigger warning module, and then receive the extension signal of the extension trigger warning module. The intelligent water retaining processing unit can judge the effectiveness of the tilt control effect of the buffer strip 3 at this time according to the received signal data change process of the lower side warning trigger component 6 (contraction signal→double disconnection signal→extension signal); After the intelligent water retaining processing unit receives the signal change process of the warning trigger component 6 located on the lower side and the signal change process of the warning trigger component 6 located on the upper side, it is judged that the forward tilting regulation of the buffer strip 3 is completed at this time, and a regulation instruction is issued to the water retaining pneumatic regulation unit. The water retaining pneumatic regulation unit promptly closes the stop valve located on the upper air path branch pipe 51 to ensure the air pressure extension effect of the regulating air bag 5 located on the upper side of the buffer regulating chamber 31, and closes the air pump mechanism to complete the regulation effect of the forward tilting water retaining surface. During floods, when the water flow continuously impacts the water retaining surface of the buffer strip 3 and the elastic connecting plate 4, the impact force can be effectively buffered by the space gap of the buffer regulating chamber 31 and the gap between the water retaining plate 2 and the elastic connecting plate 4, thereby reducing the impact damage caused by the impact force to the water retaining plate 2 and the electric push rod 12 at its rear end, improving the durability of the water retaining plate 2 and the electric push rod 12 during flood control, ensuring its flood control effect, and promoting its protection effect on the downstream area. In addition, due to the vertically distributed and forwardly tilted buffer strips 3 and elastic connecting plates 4, they can effectively The water flow impacting on the water retaining surface is drained, so that it can effectively pass through the shielding and guidance of the water retaining surface and the drainage between the water retaining plate 2 and the elastic connecting plate 4, and maintain the retention effect at the front end of the water retaining plate 2, thereby promoting the flood control effect of the water retaining plate 2, and effectively avoiding the situation where water seeps backward from the upper end of the water retaining plate 2 due to excessive water flow, further promoting the effect and strength of flood control, and in the process of the buffer bar 3 tilting forward and regulating, the intelligent water retaining processing unit can judge the effectiveness of the buffer bar 3 according to the process of the signal change of each module in the received warning trigger feedback unit. When the triggering process is abnormal, it is judged that the regulating air bag 5 or the buffer bar 3 is abnormal, and the warning lamp and the alarm are activated by the warning unit to remind and locate the abnormality, and the warning unit sends warning data to the water retaining data feedback unit, so that the water retaining data feedback unit transmits the warning data to the water conservancy project maintenance platform, which is convenient for the water conservancy project maintenance personnel to timely perform maintenance and inspection on the buffer bar 3 and the regulating air bag 5, to ensure the effectiveness of the flood control effect and fully ensure the safety of the downstream area; During the process that the water retaining pneumatic control unit acts on the regulating air bag 5, the pressure probe in the regulating air bag 5 will transmit the pressure data to the intelligent water retaining processing unit through the warning data verification unit, so that the intelligent water retaining processing unit can judge whether the abnormal deformation of the regulating air bag 5 causes the abnormality in the signal transmission change process of the warning trigger component 6 according to the pressure change in the regulating air bag 5, and further assist the water conservancy project maintenance personnel to judge the cause of the abnormality, thereby improving the efficiency of subsequent abnormal processing and ensuring the effectiveness of subsequent flood prevention; and in the process of continuous flood prevention, the water flow continuously impacts the water retaining surface of the buffer strip 3 and the elastic connecting plate 4, and the impact force of the water flow will cause the buffer strip 3 to have a certain contraction effect, and the contraction deformation of the buffer strip 3 will make The pressure in the upper and lower regulating air bags 5 produces a certain synergistic change. Since the entire water retaining surface of the buffer strip 3 is subjected to impact, the pressure in the upper and lower regulating air bags 5 will increase when impacted by the water flow. When the water flow impact ends, the pressure recovery change occurs. The intelligent water retaining processing unit can effectively judge the intensity of the flood water flow through the pressure data transmitted by the warning data verification unit, and can further assist the water conservancy project maintenance personnel to judge the flood control role at this time. It can judge the flood state according to the change of the impact force of the flood water flow, and timely regulate the subsequent flood control measures. Then, it can promote the effective promotion of flood control through digitalization and intelligentization, and improve the effectiveness of the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4. When the buffer strip 3 is partially damaged, the integrity of the water retaining surface of the buffer strip 3 is destroyed, and the elongation of the regulating air bag 5 on the upper side cannot be effectively transmitted to the water retaining surface of the buffer strip 3 on the lower side, thereby causing the elastic support strip 32 to drive the inner wall surface of the buffer regulating cavity 31 on the lower side to produce a certain elastic contraction and recovery effect, and thus the impact force of the water flow cannot be effectively transmitted, resulting in unrelated changes in the pressures in the regulating air bags 5 on the upper and lower sides. In addition, due to the damage to the integrity of the water retaining surface of the buffer strip 3 and the elastic support strip 32 driving the inner wall surface of the buffer regulating cavity 31 on the lower side to produce a certain elastic contraction and recovery effect, the front and rear surfaces of the buffer regulating cavity 31 on the lower side are The force of the two inner walls acting on the warning trigger component 6 is released, so that the elongated state of the warning trigger component 6 located on the lower side is destroyed, that is, the warning trigger ball 64 moves backward in the pomegranate-shaped elastic bag 62. The state at this time can be based on the amount of local damage to the buffer strip 3. The warning trigger ball 64 is not in contact with the rear inner wall and the inner wall of the mouth of the pomegranate-shaped elastic bag 62, and then the contraction contact block and the bottom arc piece are not in contact, and the extension contact block and the mouth arc piece are also not in contact. The double-disconnection trigger warning module is turned on and transmits a double-disconnection signal to the intelligent water retaining treatment unit, or the warning trigger ball 64 directly contacts the rear inner wall of the pomegranate-shaped elastic bag 62, so that the contraction contact block and the bottom arc piece are in contact, and the contraction contact block and the bottom arc piece are in contact. The contraction trigger warning module is conducted to transmit a contraction signal to the intelligent water retaining processing unit, and the warning trigger component 6 is restored to the contraction trigger state, so that the intelligent water retaining processing unit can judge the damage of the buffer strip 3 according to the pressure data transmitted by the warning data verification unit and the contraction signal transmitted by the contraction trigger warning module or the double disconnection signal transmitted by the double disconnection trigger warning module, and send out a warning signal and a positioning signal through the warning unit, and transmit the warning data to the water conservancy maintenance platform through the water retaining data feedback unit, so that the water conservancy project maintenance personnel can promptly perform maintenance and protection on the damaged buffer strip 3, or further protect the water retaining plate 2 at that position to ensure the retaining The water plate 2 can improve the sustainability and effectiveness of the flood control effect, and can buffer the impact of water flow during the flood control effect, while promoting the durability of the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4. It can also continuously monitor the status data of the buffer strip 3 through intelligent data monitoring, and can obtain data in time when damage abnormalities occur. While reducing the difficulty of maintenance and inspection during the flood control effect, it can also effectively realize the intelligent protection effect, play a timely and effective warning and reminder role, promote the sustained effectiveness of the water retaining effect of the water retaining plate 2 and the buffer strip 3 during the flood control effect, strive for effective time for flood control maintenance, ensure the intensity of flood control effects, and promote the role of ensuring the safety of downstream areas; During the entire flood prevention process, the intelligent water retaining processing unit will also transmit all the data of its control data to the water retaining data feedback unit, so that the water conservancy project maintenance personnel can receive the effective data of the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4 in real time through the water conservancy project maintenance platform, thereby effectively promoting the effectiveness of the water conservancy project maintenance personnel's judgment on the status of the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4, reducing the difficulty of maintenance, and can also analyze the flood status according to the data, and can timely and effectively process the water flow, fully ensuring the effectiveness of the flood prevention effect and promoting the role of ensuring the safety of the downstream areas.

[0033] Second implementation method: Figure 1 - Fig.16 A water retaining device for water conservancy project construction is shown, wherein the intelligent water retaining processing unit includes a water retaining data receiving module, the output end of the water retaining data receiving module is connected to an intelligent data processing module, and the output end of the intelligent data processing module is connected to a water retaining mode control module, a flood control mode control module, a drainage mode control module and a data output control module; The input end of the water retaining data receiving module is respectively connected to the water conservancy program setting unit, the warning trigger feedback unit, the emergency start unit and the warning data verification unit signal; the output ends of the water retaining mode control module, the flood control mode control module and the drainage mode control module are all connected to the water retaining pneumatic control unit signal; the output end of the data output control module is connected to the water retaining data feedback unit, the warning unit and the support adjustment unit signal; The water retaining mode control module, the flood control mode control module and the drainage mode control module are arranged in parallel, and form a mutual exclusive control on the water retaining pneumatic control unit. Control is a mechanism that ensures that only one operation can access shared resources at any given time. In this embodiment, during a control program, only one of the water retaining mode control module, flood control mode control module and drainage mode control module can transmit and act on the water retaining pneumatic control unit to ensure the accuracy and effectiveness of the water retaining pneumatic control unit's control and avoid the problem of poor execution due to command disorder, which affects the water retaining and flood control effects. Through the setting of the water retaining mode control module, the flood control mode control module and the drainage mode control module, while promoting the degree of automation and intelligence in the application process of the water retaining plate 2 and the buffer strip 3, the functionality of the water retaining plate 2 and the buffer strip 3 can be increased, which can be suitable for water conservancy engineering applications with different needs, increase the economic benefits of the water retaining plate 2 and the buffer strip 3, and can also improve the rapid control of the buffer strip 3 shape according to different application needs, reduce the control difficulty and shorten the control time, and promote the portability of the water retaining plate 2 and the buffer strip 3.

[0034] Figure 1 - Fig.16It is shown that during the operation of the intelligent water retaining and control system, the water retaining data receiving module in the intelligent water retaining processing unit is able to receive the setting data and control instructions transmitted by the water conservancy program setting unit, receive the conduction signals of each module in the warning trigger feedback unit, receive and convert the pressure data transmitted by the warning data verification unit and the emergency start-up instruction transmitted by the emergency start-up unit, and then transmit it to the intelligent data processing module, so that the intelligent data processing module processes and classifies the data for transmission, transmits the water retaining action instructions and related control programs to the water retaining mode control module, transmits the flood control action instructions and related control programs to the flood control mode control module, and transmits the drainage action instructions and related control programs to the drainage mode control module. The water retaining mode control module, the flood control mode control module and the drainage mode control module can directly control the water retaining pneumatic control unit according to the instructions and control data, effectively improve the control efficiency, reduce the control difficulty, promote the efficiency of the deformation of the buffer strip 3, promote the timeliness of the adjustment of the flood control effect, and improve the flood control effect and safety. Then the water retaining pneumatic control unit controls the air pump mechanism, the pressure relief valve on the air branch pipe 51 and the stop valve on the air branch pipe 51 according to the instructions and data. In addition, since the water mode control module, the flood control mode control module and the drainage mode control module are arranged in parallel and mutually exclusive control is formed on the water retaining pneumatic control unit, the effectiveness of the water retaining pneumatic control unit in receiving the instruction data can be effectively improved. The effectiveness and timeliness of the execution of the command data, at the same time, the intelligent data processing module will judge the data transmitted by each module of the warning trigger feedback unit, judge the pressure data transmitted by the warning data verification unit, and judge each data in combination with the data of the control command, and then transmit the control command data to the support control unit through the data output control module, so that the support control unit controls the electric push rod 12 to ensure the effectiveness of the water retaining, flood prevention and drainage functions of the water retaining plate 2. The data output control module will also transmit the abnormal warning data to the warning unit, and control the warning light and the alarm through the warning unit. The warning unit transmits the warning data to the water retaining data feedback unit. The data output control module will also transmit the intelligent data processing module to the support control unit. The control data of the water retaining mode control module, the flood control mode control module or the drainage mode control module is transmitted to the water retaining data feedback unit, and displayed to the water conservancy project maintenance platform through the remote signal transmitter, which can effectively promote the water conservancy project maintenance personnel to judge the application status of the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4, effectively judge the water flow data, and timely regulate, maintain and inspect the water retaining plate 2, the buffer strip 3 and the elastic connecting plate 4. It can not only effectively reduce the operating burden of the intelligent water retaining control system, reduce operating costs, and improve its data processing efficiency, but also effectively ensure the durability of the water retaining device during the application process and the continuity of its safety function, and can further ensure the safety of the downstream area.

[0035] During the drainage action, the water retaining data receiving module receives the drainage instruction transmitted by the water conservancy program setting unit, and then transmits it to the intelligent data processing module. The intelligent data processing module transmits the drainage instruction and the control data of the drainage action to the drainage mode control module. The drainage mode control module transmits the control data to the water retaining pneumatic control unit, so that the water retaining pneumatic control unit regulates the buffer strips 3 on the multiple water retaining plates 2 according to the drainage direction. At this time, according to the amount of data set for the water retaining plate 2, the elongation deformation data of the buffer strips 3 on the water retaining plate 2 can be uniformly regulated by adjusting the air bag 5, or the elongation deformation data of multiple buffer strips 3 on the same water retaining plate 2 can be individually regulated, as long as the water retaining surface formed by the buffer strips 3 and the elastic connecting plates 4 between the multiple water retaining plates 2 in the top-down perspective is formed into an inclined regulation parallel to the drainage direction, that is, in the top-down perspective, the water retaining surface formed by the buffer strips 3 and the elastic connecting plates 4 is close to the deformation position of the water retaining plate 2 in the drainage direction, and the water retaining surface formed by the buffer strips 3 and the elastic connecting plates 4 is far away. The water retaining pneumatic control unit starts the air pump mechanism to keep the upper pressure relief valve and the non-passing valve of the air branch pipe 51 in the buffer strip 3 on the water retaining plate 2 close to the drainage direction closed. For the air branch pipe 51 in the buffer strip 3 on the water retaining plate 2 away from the drainage direction, keep the upper pressure relief valve closed and the non-passing valve open, and the upper and lower air branch pipes 51 in the same buffer strip 3 are closed. The stop valves on 1 are opened and closed at the same time, so that the buffer strip 3 can form an overall uniform deformation effect, and then the length of time the stop valve on the air branch pipe 51 is closed is controlled according to the drainage direction to control the deformation size of the buffer strip 3, and then the buffer strip 3 and the elastic connecting plate 4 are linked to form a tilt control effect on the water retaining surface in a top view through the linkage effect. After the control is completed, the stop valves on the air pump mechanism and the air branch pipe 51 are closed to maintain the pressure in the air bag 5 at this time to complete the drainage control effect; During the drainage effect, since the buffer strip 3 is deformed under the action of the upper and lower regulating air bags 5, the warning trigger components 6 located on the upper and lower sides of the buffer regulating cavity 31 generate the same trigger signal transmission, and the water retaining data receiving module transmits the data signals transmitted by each module of the warning trigger feedback unit to the intelligent data processing module, so that the intelligent data processing module is based on the signal change data of the two warning trigger components 6 in the same buffer regulating cavity 31, that is, the warning trigger component 6 in the buffer strip 3 close to the drainage direction, because the warning trigger ball 64 is continuously located in the pomegranate-shaped elastic bag 62, the contact between the contraction contact block and the bottom arc piece is maintained, so that the contraction trigger warning module is turned on to generate the transmission of the contraction signal; then, the warning trigger component 6 gradually moves away from the drainage direction, and the regulating air bag 5 acts on the buffer strip 3 to gradually generate deformation. Due to the forward extension of the buffer regulating cavity 31, the warning trigger ball 64 gradually moves forward in the pomegranate-shaped elastic bag 62, and the contraction contact block and the bottom arc piece are not in contact, and the extension contact block and the mouth are When the arc pieces are not in contact, the double-disconnection trigger warning module transmits a double-end signal to the water retaining data receiving module; when the warning trigger ball 64 continues to move forward and moves to the mouth position of the pomegranate-shaped elastic package 62, the extension contact block on the warning trigger ball 64 contacts the arc piece at the mouth, so that the extension trigger warning module is turned on to transmit the extension signal to the water retaining data receiving module; after the buffer strip 3 continues to extend and deform, so that the warning trigger ball 64 is separated from the pomegranate-shaped elastic package 62, the contraction contact block and the bottom arc piece are not in contact, and the extension contact block and the arc piece at the mouth are restored to be out of contact, then the double-disconnection trigger warning module is turned on, and continues to transmit the double-disconnection signal to the water retaining data receiving module; then the intelligent data processing unit receives this signal data, judges the signal state in multiple buffer strips 3 according to the drainage direction, and judges the effectiveness of the regulation of the buffer strip 3. When it is judged that the signal change of the warning trigger component 6 in the buffer strip 3 conforms to the change law of the drainage direction, the regulation of the buffer strip 3 is effective at this time, and the buffer strip 3 remains in a normal and lossless state, which can effectively cope with the impact of water flow during drainage;When it is determined that the signal change of the warning trigger component 6 in the buffer strip 3 has a change rule that does not conform to the drainage direction, it is determined that the buffer strip 3 at this time has a control abnormality or its own damage abnormality, and then the abnormal data is verified according to the pressure data in the regulating air bag 5 transmitted by the warning data verification unit to determine whether the buffer strip 3 is abnormal. The intelligent data processing module transmits the judgment data to the data output control unit. When there is no abnormality, the control data is directly transmitted to the water conservancy project maintenance platform through the water retaining data feedback unit. When there is an abnormality, the data is transmitted to the warning unit so that the warning After the unit starts the warning light on the corresponding position water retaining plate 2 and starts the alarm on the intelligent water retaining control box, the warning unit also transmits the warning data to the water conservancy project maintenance platform through the water retaining data feedback unit, so that the water conservancy project maintenance personnel can deal with the abnormality in a timely and effective manner, thereby effectively ensuring the effectiveness of the drainage of the buffer strip 3 and the elastic connecting plate 4 water retaining surface, and can make timely and effective feedback according to the judgment data, improve the rate of drainage, reduce the water flow impact on the water retaining plate 2 and the electric push rod 12 during the drainage action, and promote the durability of the water retaining plate 2 and the electric push rod 12. ;

[0036] After the drainage and flood prevention functions are completed, the water retaining data receiving module receives the instruction data transmitted by the water flow program setting unit, converts it and transmits it to the intelligent data processing module, so that the intelligent data processing module transmits the instruction to the water retaining mode control module and the data output control module, so that the water retaining mode control module opens the pressure relief valves on all the air branch pipes 51 through the water retaining pneumatic control unit, discharges the air in the regulating air bag 5, and relieves the pressure on the regulating air bag 5, so that the regulating air bag 5 no longer drives the buffer strip 3 to stretch and deform, and under the coordinated elastic recovery effect of the buffer strip 3 itself and the elastic contraction recovery effect of the elastic support strip 32, the buffer strip 3 produces a backward shape recovery effect, so that the warning trigger component 6 in the stretched state and the warning trigger component 6 in the detached state gradually recover to the warning trigger component 6 in the contracted state, that is, the pomegranate-shaped elastic bag 6 is located. The warning trigger ball 64 at the mouth position moves backward in the pomegranate-shaped elastic bag 62 through the action of the support rod 63 under the recovery action of the front end of the buffer adjustment chamber 31, so that the warning trigger ball 64 contacts the rear inner wall of the pomegranate-shaped elastic bag 62, and the contraction contact block and the bottom-touching arc piece resume the abutment action; the warning trigger ball 64 located outside the pomegranate-shaped elastic bag 62 gradually approaches the opening position of the pomegranate-shaped elastic bag 62 under the recovery deformation of the buffer adjustment chamber 31 and the driving of the support rod 63, and then the warning trigger ball 64 squeezes the elastic cone strip 61 and the pomegranate-shaped elastic bag 62, causing the opening of the pomegranate-shaped elastic bag 62 to deform, that is, forming the warning trigger component 6 in the reset state, and then the warning trigger ball 64 enters the pomegranate-shaped elastic bag 62 through the deformation action of the pomegranate-shaped elastic bag 62, and continuously moves backward, so that the warning trigger ball 64 contacts the rear inner wall of the pomegranate-shaped elastic bag 62, and the contraction contact block and the bottom-touching arc piece resume the abutment action;The water-blocking data receiving module synchronously transmits the signal data it receives to the intelligent data processing module. The intelligent data processing module determines whether the warning trigger component 6 has recovered to the contracted state according to whether the contraction signal transmitted by the contraction trigger warning module is received, and then determines the recovery state of the buffer bar 3 at this time. After receiving the contraction signal, it is determined that the buffer bar 3 has recovered to normal. When the contraction signal is not received and the pressure data transmitted by the warning data verification unit is used to adjust the air bag 5 to have been completely depressurized, it is determined that the buffer bar 3 has recovered abnormally at this time, and a signal is sent to the warning unit through the data output control module, and the warning light and the alarm generate a positioning signal and a warning signal At the same time, the water retaining data feedback unit outputs a warning signal to the water conservancy project maintenance personnel through the water conservancy project maintenance platform according to the warning data transmitted by the warning unit, so that the water conservancy project maintenance personnel can timely maintain and repair the abnormal buffer strip 3 to ensure the effectiveness of the subsequent water retaining effect, the durability of the water retaining plate 2 and the electric push rod 12, and the effectiveness of the subsequent flood control and drainage effect regulation. At the same time, the data output regulation module will also control the support regulation unit to continuously adjust the support angle of the electric push rod 12 to avoid stress damage caused by continuous action on the same position during the water retaining effect, and extend the service life of the buffer strip 3 and the elastic connecting plate 4. ;
