Description
Technical Field
[0001] This utility model belongs to the field of drainage technology for grain storage facilities, and specifically relates to an intelligent drainage device for grain storage areas. Background Technology
[0002] my country is a typical monsoon climate zone with significant seasonal variations in precipitation. Rainfall during the rainy season (such as summer) can account for about 70% of the annual total, and heavy rains and storms are common during this period. This can lead to flooding in grain depots or backflow of water, directly causing grain to become damp and moldy, resulting in significant economic losses. At the same time, large amounts of rainwater are discharged without being effectively utilized, leading to water waste and environmental pollution.
[0003] As important grain storage facilities, grain depots have unique drainage requirements: most grain depots are located in remote areas and lack adequate municipal drainage conditions; the roads within the storage area are mostly paved, resulting in a high rainwater runoff coefficient and a large instantaneous drainage volume; and there are often significant water level differences between the grain depot and the external rainwater system or in the surrounding rivers, making it difficult for traditional drainage facilities to meet the demand for efficient drainage.
[0004] Existing conventional rainwater lifting devices have significant drawbacks: First, their operation is limited to a single condition, adapting only to fixed rainfall scenarios and unable to flexibly adjust drainage modes according to rainfall intensity, leading to excessive energy consumption or untimely drainage. Second, their outflow pattern is fixed, with only a single outflow direction, making it difficult to cope with varying water level differences and susceptible to backflow from external floods. Third, their automation level is low, relying on manual monitoring and operation, resulting in high maintenance costs and delayed fault response. Therefore, there is an urgent need for an integrated, intelligent, and multi-condition adaptable grain depot drainage system to solve these problems. Utility Model Content
[0005] In view of this, this utility model addresses the shortcomings of the existing technology by providing an intelligent drainage device for grain storage areas. It can adaptively adjust to multiple operating conditions based on rainfall, automatically switching drainage modes according to the amount of rainfall and the elevation of the end inspection well, maximizing the efficiency of different outflow methods, and significantly improving energy saving and drainage efficiency.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an intelligent drainage device for grain storage areas, including a concrete rainwater inspection well, an auxiliary drainage well and an early warning monitoring module. A pressurized water outlet pipe is installed between the concrete rainwater inspection well and the auxiliary drainage well. An auxiliary rainwater lifting integrated device is fixed inside the auxiliary drainage well by anchor bolts. A pump station module is installed inside the auxiliary rainwater lifting integrated device. A drainage pipe module is installed inside the concrete rainwater inspection well.

A gate valve is fixedly installed on the upper side of the Y-type filter. A pump station outlet pipe is fixedly installed on the upper side of the gate valve. The pump station outlet pipe is fixedly installed in the drain outlet B of the auxiliary drainage well.
[0009] The early warning monitoring module is communicatively connected to the control module, and the control module is controlled by the pumping station module and the drainage pipeline module. The early warning monitoring module includes water level monitoring points and road water accumulation detection cameras set in the reservoir area, used to monitor the water level in the reservoir area, identify water accumulation sections, and generate early warning signals. The early warning monitoring module also includes an intelligent management platform, which can receive real-time data from the water level monitoring points and water accumulation detection cameras, realize remote wireless data transmission, automatically generate operation reports, and provide mobile monitoring functions.

[0011] As a further improvement of this utility model, an electric gate A is installed on the upper side of the concrete rainwater inspection well via an electric gate operating valve A, and an electric gate B is installed via an electric gate operating valve B.

[0030] The early warning monitoring module is communicatively connected to the control module, and the control module is controlled by the pumping station module and the drainage pipeline module. The early warning monitoring module includes water level monitoring points and road water accumulation detection cameras set in the reservoir area, used to monitor the water level in the reservoir area, identify water accumulation sections, and generate early warning signals. An electric gate A104 is set on the upper side of the concrete rainwater inspection well 101 through an electric gate operating valve A, and an electric gate B109 is set through an electric gate operating valve B203. The electric gate A104 is installed in conjunction with the pressureless drainage pipe 103, and the electric gate B109 is installed in conjunction with the pressurized water outlet pipe 108.
[0031] like Figure 1As shown, a hook A204 is installed at the bottom of the concrete rainwater inspection well 101, and a level gauge A205 is installed on the hook A204. A hook B206 is fixedly installed at the top of the auxiliary drainage well 105, and a level gauge B207 is installed on the hook B206. A grid 111 is installed at the end of the pressureless drainage pipe 103 located inside the auxiliary drainage well 105. A ventilation pipe assembly 202 is installed on the upper side of the auxiliary drainage well 105.
[0032] like Figure 1 , 2 As shown, the early warning monitoring module also includes an intelligent management platform. The intelligent management platform can receive real-time data from water level monitoring points and water accumulation detection cameras, realize remote wireless data transmission, automatically generate operation reports, and provide mobile monitoring functions. A control cabinet 301 is installed on the upper side of the auxiliary drainage well 105. The control cabinet 301 is used to receive early warning signals from the early warning monitoring module and liquid level information from water level monitoring points, and control the start and stop of the water pump and the opening and closing status of electric gate A and electric gate B according to preset parameters.
[0033] Water level monitoring points (liquid level gauges) are set up in low-lying areas of the reservoir and inlet wells of pumping stations through an early warning monitoring module to collect liquid level data in real time; high-definition water accumulation detection cameras are installed on the main roads of the reservoir to identify the depth and range of water accumulation; rain sensors are installed on roofs to monitor rainfall intensity; all monitoring data are transmitted to an intelligent management platform, which supports remote data viewing, fault alarms and mobile APP monitoring.
[0034] Two submersible sewage pumps 112 (one in use and one on standby) are used. The submersible sewage pump 112 is a self-coupling vertical wet-installation, integrated with the inlet well in the same reinforced concrete well cylinder. A steel maintenance platform is set inside the well cylinder, and a control panel is set on the ground for easy equipment maintenance.

The pipe diameter is determined according to the drainage flow rate. The pipeline layout is laid along the edge of the storage area road to reduce interference with the storage area. The electric gate A104 and the electric gate B109 are both made of stainless steel. The electric gate A104 is linked to the pressureless drainage pipe 103, and the electric gate B109 is linked to the pressurized outlet pipe 108.
[0036] The control cabinet 301 is an outdoor floor-standing type. The shell is welded from 304 stainless steel with an IP65 protection rating.

It can automatically receive signals from the liquid level gauge and sensor and execute control commands.
[0037] Workflow:
[0038] During system operation, the early warning monitoring module collects real-time data on reservoir liquid level, rainfall, and water accumulation, and transmits this data to control cabinet 301. Control cabinet 301 automatically switches to the following three operating conditions based on the elevation of the concrete rainwater inspection well 101 and the early warning signal:
[0039] Operating Condition 1 (Small to Medium Rainfall Scenario): When the elevation of the concrete rainwater inspection well 101 is lower than the small to medium rainfall level, and the roof rainwater sensor and road water accumulation sensor do not issue a warning, the control cabinet 301 controls the electric gate A104 and electric gate B109 to open simultaneously. The rainwater in the reservoir area is discharged through a combination of gravity flow and equipment lifting, and the auxiliary rainwater lifting integrated equipment 1069 is started to quickly discharge the accumulated water.
[0040] Operating Condition 2 (Medium to Heavy Rainfall Scenario): When the elevation of the concrete rainwater inspection well 101 is between the level of medium to heavy rainfall and the level of torrential rain, and the sensor issues a low water level warning, the control cabinet 301 controls the electric gate A104 to open and the electric gate B109 to close. Rainwater is discharged only by gravity, and the submersible sewage pump 112 stops operating to reduce energy consumption.
[0041] Operating Condition 3 (Rainstorm and Backflow Scenario): When the elevation of the concrete rainwater inspection well 101 is higher than the rainwater level and the sensor issues a high water level warning, the control cabinet 301 controls the electric gate A104 to close, and the electric gate B109 and the submersible pump 112 to open. Rainwater is discharged through the full power of the equipment, and the external backflow path is blocked by the full start of the submersible pump 112.
[0042] When the pump station liquid level reaches the preset opening threshold, the control cabinet 301 automatically starts and stops the electric gate A104, electric gate B109 and submersible sewage pump 112, and repeats the cycle to achieve automated drainage.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
