Description

Technical Field

[0001] The present invention belongs to the technical field of water retaining and drainage for urban flood control during flood season, and specifically is an integrated flood emergency water storage, retaining and drainage system. Background Art

[0002] With the rapid development of urbanization, the infrastructure of many cities, especially the components of underground drainage pipe systems, are aging and prone to blockage and siltation. Blocked pipes will affect the normal drainage function. When a city encounters a sudden rainstorm, it is very likely that the accumulated water cannot be discharged in time, causing the accumulated water to gather in the low-lying areas of the city, thus causing floods and affecting the safety of people's lives and property. Regarding disasters caused by floods, traditional water-blocking methods include artificial sandbags or quickly assembled water retaining boards. Traditional sandbag water-blocking, a flood control and waterlogging prevention solution that relies solely on manpower and has no systematic flood response products, is inevitably prone to poor reliability, piled sandbags are prone to leakage and collapse, subjective judgment of water-blocking timing is prone to errors, response is not timely, response to emergencies is slow, and special personnel are required to be on duty to waste human resources.

[0003] As for flood-proof products, a non-automatic floodgate is a type of floodgate that first installs the floodgate frame and base at the garage entrance. When a flood disaster occurs, the columns and baffles between the columns are quickly installed at the reserved positions on the base by manpower, and the floodgate is quickly built using quick screws to achieve the purpose of flood control. However, this method only replaces the sandbags used in traditional flood control with aluminum alloy structural parts that have been specifically designed, avoiding the leakage problem caused by unreasonable sandbag stacking, improving the reliability and safety of flood control, and avoiding sandbag stacking. Although the ground is in disarray, the essence is that manpower is needed to prevent floods when they occur. The main problems of manpower flood prevention have not been overcome. For example, when the water level rises sharply during heavy rain, the installation of flood gates will cause safety hazards and installation difficulties; the subjective judgment of dangerous situations is unreliable, resulting in waste of construction and human resources, and there will be a dilemma that the flood situation has been lifted before the baffle is installed; the disassembly and assembly of the sluice gates before and after the flood prevention requires the cooperation of many people, and there are high requirements on the quality of the installation personnel and their mutual cooperation; at the same time, because the installation takes time, the response to sudden floods will not be timely enough.

[0004] Therefore, it is particularly important to develop an automatic water retaining device that can make quick and necessary responses according to flood conditions and realize a complete set of design solutions for real-time water retaining monitoring and continuous water storage, water retaining and drainage. Summary of the invention

[0005] The present invention aims to solve the problems existing in traditional artificial water retaining and flood prevention, such as potential safety hazards, inaccurate subjective judgment on the timing of water retaining, untimely response, slow response to emergencies, and the need for dedicated personnel on duty which wastes manpower and material resources. The present water retaining scheme and a complete set of systematic methods for responding to flood situations can respond to flood situations objectively and reasonably through the rising water level and the information measured by the water gauge, and the response is rapid and reliable. The entire system is a closed-loop stable system that can automatically respond in real time. When the response is abnormal, it will alarm the central control and the relevant personnel will be responsible for maintenance.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an integrated flood emergency water storage, water retaining and drainage system, including a river simulation system, an active lifting and water retaining system and a forced drainage system, wherein the river simulation system, the active lifting and water retaining system and the forced drainage system are all designed with different mechanisms inside a square acrylic box to achieve lifting and water retaining and forced drainage simulation of actual flood conditions; The system is equipped with a rainfall simulation system, which realizes the rainfall environment of the water retaining module by controlling the manipulator valve. Initially, the water retaining system drains water outwards by natural gravity into the river channel. When the water level in the river channel rises due to the drainage situation and the water inside the module cannot be drained into the river channel by gravity, the water level inside the module will continue to rise and the water retaining module will start to work, simulating the situation in reality where the water level of ground water will continue to rise when heavy rainfall cannot be discharged well. At the same time, the water retaining mechanism can ensure that the accumulated water will not flow into the basement, subway or some low water level areas in large quantities. When the accumulated water level of precipitation in a certain environment increases to the limit value, the submersible pump in the forced drainage system starts to work and sends water from the low water level to the high water level to ensure that the water level in the water retaining module will not exceed the water retaining mechanism and cause flood disasters.

[0007] An integrated flood emergency water storage, water retaining and drainage equipment, the system is connected by a set river model and a passive water retaining system model, an active lifting and lowering water retaining model, a forced drainage system model and a pipeline model to realize a closed-loop strategy for coping with flood conditions.

[0008] Preferably, the river model consists of a first acrylic square cylinder, a first electronic water gauge, a first electric ball valve with feedback, a river inlet pipeline and a river outlet pipeline.

[0009] Preferably, the ends of the inlet and outlet pipes connected to the cylinder body are both provided with flanges, and the pipes are connected to the cylinder body through the flanges, with a rubber sealing pad in the middle as a seal at the connection to prevent water leakage from the connection; The first electronic water gauge in the river channel is set with a limit value. When the water level in the river channel reaches the limit value of the electronic water gauge in the river channel, the first electric ball valve on the drainage passage to the outside of the river channel opens to discharge the water in the river channel to prevent overflow.

[0010] Preferably, the active lifting water retaining model consists of a second acrylic square cylinder, a scene terrain main component, a lifting mechanism component, a second electronic water gauge, a slide rail component, an external drain pipe, a water inlet pipe, an input pipeline control manipulator valve, an output pipeline and an output pipeline electric control ball valve.

[0011] Preferably, the scene terrain main component is processed with acrylic material, and is bonded to the cylinder body inside the cylinder body to form the main part of the scene simulation, which is mainly divided into three parts: front and rear water storage parts and the middle water-free part; The third and second electronic water gauges are respectively set in the front and rear water storage parts, and both are set with limits. When the water level in any cavity reaches the limit, the forced drainage system will be turned on to pump the water inside the module out to the river simulation system. When the module opens the hand valve, water will enter the system from the water inlet pipe, and the water level will accumulate in the first water storage tank on the right. When the water level reaches a limit, the second electronic water gauge will feed back the signal to the central control, and the control terminal will drive the motor to rotate. The motor will slowly raise the lift door through the transmission of the gear rack, and then the distance sensor will always keep the lifting height of the lift door in line with the water level and always higher than the water level. When the water level continues to rise to the maximum water retaining limit, the third electronic water gauge will transmit the information back to the central control, and the central control will turn on the forced drainage pump to pump the water inside the module into the river simulation system. A rack is installed on the main lifting water retaining plate of the module, and the motor is fixed by a motor bracket. A gear with a boss is installed on the motor output shaft, and the gear is meshed with the rack.

[0012] Preferably, the forced exhaust system model consists of a square acrylic cylinder, a forced exhaust compartment upper cover, a pipeline compartment upper cover, a second electric ball valve, a third electric ball valve, a drop-in water depth gauge, and a submersible pump; It consists of a connecting hose between the submersible pump and the first forced exhaust pipeline, a natural drainage pipeline, the first forced exhaust pipeline, the second forced exhaust pipeline and a collecting pipeline.

[0013] Preferably, the square acrylic cylinder is divided into two chambers, one of which is a water storage chamber with a built-in forced drainage submersible pump, and the chamber will be directly connected to the water storage chamber of the barrier model; When precipitation begins in the water retaining module, the water can be naturally discharged to the water storage chamber through the pipeline at the first time. The water in the water storage chamber will be discharged into the river simulation system through the natural drainage pipe first. However, as the water level inside the river continues to rise, natural drainage can no longer meet the demand. At this time, the forced discharge submersible pump will receive an instruction to start forced discharge. Before the forced discharge submersible pump is about to start, the second electric ball valve will be opened, and the third electric ball valve will be closed. The water in the water storage chamber will be pumped into the collecting pipeline through the second forced discharge pipeline by the submersible pump, and then pumped out to the river.

[0014] Preferably, the pipeline model is composed of multiple acrylic pipes, three-way joints, four-way joints, right-angle elbows, pipeline support frames, electric ball valves with feedback, manipulator valves, and single-head closed acrylic rainfall simulation tubes.

[0015] Preferably, the acrylic tubes are directly connected by pipe threads, and the acrylic tubes are directly screwed with the electric ball valve and the manipulator valve by matching threads; Among them, the pipeline model includes the main water inlet pipe, the water inlet pipe of the lifting water retaining system, the water outlet pipe of the lifting water retaining system, the spare water inlet elbows of other flip-blocking systems, the main water outlet pipe after passing through the forced discharge system, the low pipe bracket and the high pipe bracket.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The above integrated system solution for solving flood and waterlogging of the present invention has improved the background technology in many aspects and added effects that the original background technology did not have. First of all, with regard to the improvement of the background technology, the water-blocking method does not adopt the technology of temporarily installing water-blocking products, but adopts the technology of water-blocking products pre-buried in the basement of the community or at the entrance of the subway supermarket. This product technology does not affect normal traffic when there is no flood, and can respond quickly, timely and appropriately when there is a flood, without human intervention. It greatly solves the problems of inaccurate subjective judgment, untimely response, slow response to emergencies, and the need for special personnel on duty to waste manpower and material resources; with regard to the increase in background technology, in addition to water blocking, the entire system introduces a complete set of system logic methods for flood control, storage, blocking and drainage. After the front end completes water blocking, the blocked accumulated water will pass through the strong drainage part of the system and discharge the accumulated water into the river; when the water level recedes, the water blocking mechanism is reset.

[0017] The lifting and lowering water retaining model in the present invention is an active water retaining method. When the rainfall is rapid and the accumulated water is not discharged in time, resulting in accumulation, the electronic water gauge in the system will communicate with the motor controlling the lifting and lowering gate according to the rising water level. When the water level reaches the limit, the driving motor will operate. At the same time, the electronic gate is also provided with a distance sensor, which will drive the motor to control the gate to follow the rising water level to ensure that the gate is always raised higher than the accumulated water level, thereby playing a water blocking role. The forced drainage system is when the water retaining system reaches the maximum water retaining position and the water level is still rising. The forced drainage system is turned on at a certain extreme value. The forced drainage system uses a submersible pump to remove the water from the water retaining system at the fastest speed. The accumulated water in the system is pumped out, and the forced drainage system is turned on when there is no natural drainage or the water level reaches the limit value, which has relieved the water blocking pressure and ensured the stability and reliability of the water retaining system, fundamentally solving the flood situation and waterlogging; the mutual cooperation and human-computer interaction between these systems are realized through the central control end; and the connection between systems, the liquid circuits of the simulated rainfall module, the drainage module, etc. are all connected and pumped out by liquid flow pipelines; the present invention combines a complete model system for responding to flood situations, such as a water retaining system, a forced drainage system, and a simulated rainfall system, and is a complete set of flood control and waterlogging solutions, which can greatly reduce the impact of floods and protect people's lives and property safety.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the present invention provides an integrated flood emergency water storage, water retaining and drainage system, including a river simulation system, an active lifting and water retaining system and a forced drainage system, wherein the river simulation system, the active lifting and water retaining system and the forced drainage system are all designed with different mechanisms inside a square acrylic box to achieve lifting and water retaining and forced drainage simulation of actual flood conditions; The system is equipped with a rainfall simulation system, which realizes the rainfall environment of the water retaining module by controlling the manipulator valve. Initially, the water retaining system drains water outwards by natural gravity into the river channel. When the water level in the river channel rises due to the drainage situation and the water inside the module cannot be drained into the river channel by gravity, the water level inside the module will continue to rise and the water retaining module will start to work, simulating the situation in reality where the water level of ground water will continue to rise when heavy rainfall cannot be discharged well. At the same time, the water retaining mechanism can ensure that the accumulated water will not flow into the basement, subway or some low water level areas in large quantities. When the accumulated water level of precipitation in a certain environment increases to the limit value, the submersible pump in the forced drainage system starts to work and sends water from the low water level to the high water level to ensure that the water level in the water retaining module will not exceed the water retaining mechanism and cause flood disasters.

[0022] An integrated flood emergency water storage, water retaining and drainage equipment, the system is connected by a set river model 1 and a passive water retaining system model 2, an active lifting water retaining model 3, a forced drainage system model 4 and a pipeline model 5 to realize a closed-loop strategy for coping with flood conditions.

[0023] like Figure 1 and Figure 2 As shown, the river model 1 is composed of a first acrylic square cylinder 1-4, a first electronic water gauge 1-3, a first electric ball valve with feedback 1-2, a river inlet pipeline 1-5 and a river outlet pipeline 1-1.

[0024] like Figure 1 and Figure 2 As shown, the ends of the pipes of the inlet pipe 1-5 and the outlet pipe 1-1 connected to the cylinder body are both provided with flanges, and the pipes are connected to the cylinder body through the flanges, and a rubber sealing pad is provided in the middle as a seal at the connection to prevent water leakage from the connection; The first electronic water gauge 1-3 in the river channel is set with a limit value. When the water level in the river channel reaches the limit value of the electronic water gauge in the river channel, the first electric ball valve 1-2 on the drainage passage to the outside of the river channel opens to discharge the water in the river channel to the outside to prevent overflow.

[0025] like Figure 3 As shown, the active lifting water retaining model 3 consists of a second acrylic square cylinder 3-1, a scene terrain main component 3-3, a lifting mechanism component 3-4, a second electronic water gauge 3-2, a slide rail component 3-5, an external drain pipe 3-6, a water inlet pipe 3-9, an input pipeline control manipulator valve 3-10, an output pipeline 3-7 and an output pipeline electric control ball valve 3-8.

[0026] like Figure 3 and Figure 4 As shown, the scene terrain main component 3-3 is processed with acrylic material and bonded with the cylinder body inside the cylinder body to form the main part of the scene simulation, which is mainly divided into three parts: the front and rear water storage parts and the middle water-free part; The front and rear water storage parts are respectively provided with a third electronic water gauge 3-11 and a second electronic water gauge 3-2, both of which are provided with limits. When the water level in any cavity reaches the limit, the forced drainage system will be activated to pump the water inside the module out to the river simulation system. When the module opens the hand valve 3-10, water will enter the system from the water inlet pipe 3-9, and the water level will accumulate in the first water storage tank on the right. When the water level reaches a limit, the second electronic water gauge 3-2 will feed back the signal to the central control, and the control terminal will drive the motor 3-4-3 to rotate. The motor 3-4-3 slowly raises the lifting door through the transmission of the gear rack 3-4-4, and then the distance sensor is used to always keep the lifting height of the lifting door in line with the water level and always higher than the water level. When the water level continues to rise to the maximum limit of water retaining, the third electronic water gauge 3-11 will transmit the information back to the central control, and the central control will turn on the forced discharge pump to pump the water inside the module to the river simulation system. A rack is installed on the main lifting water retaining plate 3-4-1 of the module, and the motor 3-4-3 is fixed by the motor bracket 3-4-5. The motor output shaft is installed with a gear with a boss, and the gear is meshed with the rack; The lifting door is controlled to rise and fall by the reciprocating motion of the motor. At the same time, the water baffle 3-4-1 is also connected to the two slide rail assemblies 3-5 to ensure that the vertical movement direction of the lifting door is not offset. A groove is set between the lifting door and the lifting door slide, and the sealing strip 3-4-2 is buried and firmly bonded with strong glue, so that when the door is reciprocating, the gap of relative movement can be guaranteed to be watertight. When the water is first poured into the rear water storage cavity by accident, the second electronic water gauge 3-2 will first drain the water forward by natural drainage. When the water level is getting higher and higher and the natural drainage cannot meet the requirements, the second electronic water gauge 3-2 also has a water level limit. When the water level reaches this limit, the forced discharge system will also be triggered to pump the water inside the rear water storage cavity into the river through the front water storage cavity to alleviate the harm caused by the continuous accumulation of water level.

[0027] like Figure 5 As shown, the forced exhaust system model 4 consists of a square acrylic cylinder 4-8, a forced exhaust compartment upper cover 4-1, a pipeline compartment upper cover 4-9, a second electric ball valve 4-5, a third electric ball valve 4-10, a immersion depth measuring instrument 4-12, and a submersible pump 4-2; The submersible pump 4-2 is connected to the first forced drainage pipeline 4-4 by a connecting hose 4-13, a natural drainage pipeline 4-11, the first forced drainage pipeline 4-4, the second forced drainage pipeline 4-6 and a collecting pipeline 4-7.

[0028] like Figure 5As shown, the square acrylic cylinder 4-8 is divided into two chambers, one of which is a water storage chamber with a built-in forced drainage submersible pump 4-2, and the chamber will be directly connected to the water storage chamber of the blocking model; When precipitation begins in the water retaining module, water energy will be naturally discharged to the water storage chamber through the pipeline at the first time. The water in the water storage chamber will be discharged into the river simulation system through the natural drainage pipe first. However, as the water level in the river continues to rise, natural drainage can no longer meet the demand. At this time, the forced drainage submersible pump 4-2 will receive an instruction to start forced drainage. Before the forced drainage submersible pump is about to start, the second electric ball valve 4-5 will be opened, and the third electric ball valve 4-10 will be closed. The water in the water storage chamber will be pumped into the collection pipeline 4-7 through the second forced drainage pipeline 4-6 through the submersible pump 4-2, and then pumped out to the river; When the submersible pump continues to work and the continuous precipitation in the water retaining module stops, the water in the water storage chamber of the forced drainage system will become less and less, and the water level will drop rapidly. When the water level measured by the immersion depth meter is lower than a certain limit, the forced drainage system will be shut down. At this time, the forced drainage pump 4-2 is closed, the second electric ball valve 4-5 is closed, and the third electric ball valve 4-10 is opened to restore the gravity natural drainage system.

[0029] like Figure 6 As shown, the pipeline model 5 is composed of multiple acrylic pipes, three-way joints, four-way joints, right-angle elbows, pipeline support frames, electric ball valves with feedback, manipulator valves, and single-head closed acrylic rainfall simulation pipes; The acrylic tubes are directly connected by pipe threads, and the acrylic tubes and electric ball valves and manipulator valves are matched with threaded direct screws; This connection method makes the assembly and disassembly of the entire device more convenient; Among them, the pipeline model 5 includes the main water inlet pipe 5-1, the water inlet pipe 5-3 of the lifting water retaining system, the water outlet pipe 5-5 of the lifting water retaining system, the spare water inlet elbow 5-4 of other flip-blocking systems, the main water outlet pipe 5-9 after passing through the forced discharge system, the low pipe bracket 5-7 and the high pipe bracket 5-8.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
