Description

Technical Field

[0001] The utility model belongs to the technical field of concrete foundation maintenance, in particular to a drip irrigation device for mass concrete foundation maintenance. Background Art

[0002] The investigation found that in the current construction operations, in the process of curing large-volume concrete foundations, plastic buckets or soft plastic pipes are mainly used manually to first sprinkle curing water on the large-volume concrete foundation, and then an airtight film or breathable felt cloth is laid on the large-volume concrete foundation to complete the curing of the large-volume concrete foundation.

[0003] Such extensive concrete maintenance is no longer suitable for current construction technology and engineering quality requirements, especially for large-volume concrete foundations with special requirements such as large volume, large internal and external temperature difference, and heavy equipment quality in the later stage. Under the stringent requirements of engineering excellence and quality reaching the fine craft standards, the current extensive large-volume concrete foundation maintenance method of sprinkling water and covering with film is completely unable to meet the current process quality requirements.

[0004] 1. The maintenance of large-volume concrete foundations depends entirely on construction experience. In terms of the current maintenance method of large-volume concrete foundations, which involves pouring water and covering with plastic film, water quickly flows from the surface of the concrete foundation and cannot be well absorbed by the large-volume concrete, resulting in quality problems such as cracking of the concrete foundation. At the same time, it is difficult for the maintenance personnel to judge the humidity of the concrete foundation surface, and thus they do not know when to perform maintenance by pouring water on the concrete foundation. Therefore, maintenance personnel rely entirely on construction experience to perform maintenance on large-volume concrete foundations, and are unable to scientifically determine the maintenance time.

[0005] 2. There is a large waste of water resources in the maintenance of large-volume concrete foundations. Referring to the current water consumption for the maintenance of large-volume concrete foundations, due to the large volume of the concrete foundation and the large temperature difference between the inside and the outside, the concrete will emit a large amount of heat energy when solidifying. Therefore, in the maintenance of large-volume concrete, water will be poured on the surface of the concrete foundation for many times for maintenance. The water poured on the concrete quickly flows to the ground of the foundation, and the water resources only flow through the surface of the concrete foundation, resulting in a large waste of water resources, which is more obvious in the water-scarce areas in northwest my country.

[0006] Therefore, the conventional large-volume concrete foundation maintenance method of covering with a film by splashing water often has problems in actual operations, such as substandard maintenance process, inability to judge the maintenance time well, and resulting in a large amount of water resource waste. Utility Model Content

[0007] The purpose of the utility model is to provide a large-volume concrete foundation maintenance drip irrigation device that can monitor humidity in real time to achieve precise maintenance, save water resources and meet the large-volume concrete foundation maintenance standards in response to the problems existing in the prior art; the maintenance drip irrigation device realizes drip irrigation maintenance of large-volume concrete foundations through electrical automatic control, and realizes the large-volume concrete foundation maintenance that meets the technical standards of constant humidity and the energy-saving function of water saving and environmental protection.

[0008] The purpose of the utility model is solved by the following technical solutions:

[0009] A large-volume concrete foundation maintenance drip irrigation device, characterized in that: the maintenance drip irrigation device includes a drip irrigation pipe network covering the large-volume concrete foundation, a humidity sensor arranged on the surface of the large-volume concrete foundation in the drip irrigation pipe network area, a control cabinet, a submersible pump arranged in a water tank, and a water supply main connecting the water outlet of the submersible pump and the water inlet of the drip irrigation pipe network, the humidity sensor and the submersible pump are respectively connected to the control cabinet through signal lines, and the large-volume concrete foundation surface humidity signal transmitted by the humidity sensor to the control cabinet is used as a start signal for the submersible pump.

[0010] The continuous working time of the submersible pump is set by the control cabinet.

[0011] The continuous working time of the submersible pump is a specific time value between 1 minute and 10 minutes.

[0012] The drip irrigation pipe network is composed of water supply branches that intersect each other in a cross shape, and drip holes are opened on the water supply branches.

[0013] The drip irrigation pipe network is covered with a breathable tarpaulin, which can be covered on a large-volume concrete foundation, and the drip irrigation pipe network and humidity sensor are covered on the surface of the large-volume concrete foundation to ensure that the drip irrigation concrete curing water will not be lost and evaporated quickly, and also ensure the air permeability of the large-volume concrete foundation and the outside world; the edge of the breathable tarpaulin is installed with a vertical hanging ring to prevent the breathable tarpaulin from being blown up by strong winds.

[0014] The water supply main is provided with a solenoid valve, which is connected to the control cabinet via a signal line and can be linked with the submersible pump.

[0015] A pressure gauge is arranged on the water supply main and is connected to the control cabinet through a signal line; the pressure gauge monitors the real-time water pressure and transmits the pressure signal to the control cabinet to determine the water pressure of the water supply main. When the solenoid valve is not opened and the water pressure is too high, or the submersible pump is not started and the pressure is too low, the pressure signal of the pressure gauge is transmitted to the control cabinet, which is determined to be a system failure and the control cabinet issues a shutdown command.

[0016] A filter is arranged on the water supply main pipe, and the filter is arranged on the outlet side of the submersible pump and outside the water tank.

[0017] In terms of the arrangement of filters, pressure gauges and solenoid valves, filters, pressure gauges and solenoid valves are arranged in sequence on the water supply main on the rear side of the submersible pump to complete the filtering treatment, pressure monitoring and switch switching of the maintenance water in the water tank, so that water can flow out to the drip holes of the water supply branch pipe to achieve the function of drip irrigation.

[0018] The control cabinet is powered by a battery pack, and a power line row is arranged in the control cabinet. Through electrical connection, the electric energy in the battery pack is distributed to the submersible pump and the solenoid valve to meet the action electric energy demand.

[0019] The battery pack and inverter are arranged in one device and the inverter is connected to the photovoltaic solar panel through a line. The photovoltaic solar panel stores the converted electric energy in the battery pack through the inverter, realizing the processing and storage of the electric energy converted by the photovoltaic solar panel to supply energy for the electrical components.

[0020] In the above device, the control cabinet is the core component of signal reception and processing. It receives the water pressure signal from the pressure gauge monitoring the water supply main and the humidity signal from the humidity sensor monitoring the humidity signal of the large volume concrete surface, and can process the received signals. According to the data processing results, it issues instructions to start and stop the submersible pump and switch the solenoid valve. At the same time, the energy conversion, water supply and distribution required for the entire drip irrigation maintenance device are realized under the control signal transmission of the control cabinet to complete the drip irrigation control.

[0021] After receiving the humidity signal from the humidity sensor placed on the surface of the mass concrete foundation, the control cabinet makes a judgment. When drip irrigation maintenance is needed, it sends an action signal to start the submersible pump and open the solenoid valve. The pressure gauge monitors the real-time water pressure and transmits the pressure signal to the control cabinet to determine whether the pressure is qualified. The water in the water tank is passed through the drip holes on the water supply main and the water supply branch pipe to perform drip irrigation on the mass concrete foundation.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] The large-volume concrete foundation maintenance drip irrigation device provided by the utility model uses a controller in a control cabinet to analyze and judge the humidity on the surface of the large-volume concrete foundation collected by a humidity sensor to determine whether it is necessary to start a submersible pump and an electromagnetic valve to provide maintenance water for drip irrigation maintenance of the concrete, thereby achieving precise control of the maintenance of the concrete foundation, breaking the current extensive maintenance method of manual water pouring maintenance based on experience, greatly improving the technicality of the concrete foundation maintenance, and achieving real-time maintenance of the large-volume concrete foundation.

[0024] The large-volume concrete foundation maintenance drip irrigation device provided by the utility model pumps water in a water tank into a water supply main pipe through a submersible pump, the water flows through a filter to filter impurities in the water to avoid clogging the drip hole, the water flows into a water supply branch pipe after passing through a switch controlled by an electromagnetic valve, the water supply branch pipe is laid on the surface of the large-volume concrete foundation so that the water in the water supply branch pipe can fall on the surface of the concrete foundation after passing through the drip hole; the breathable tarpaulin covers the top of the water supply branch pipe, and can also cover the large-volume concrete foundation to avoid rapid evaporation of the maintenance water flowing out of the drip hole, and at the same time is breathable, so that the concrete releases heat during the solidification process and is lost through the breathable tarpaulin; the four corners of the breathable tarpaulin are provided with vertical weight hanging rings to realize the function of hanging heavy objects to prevent the breathable tarpaulin or the water supply branch pipe from being blown up by strong wind; the entire water flow is controlled by a controller in a control cabinet to realize the function of drip irrigation for the maintenance of the entire large-volume concrete foundation.

[0025] Compared with the current large-volume concrete maintenance foundation artificial watering and covering with plastic film, the large-volume concrete foundation maintenance drip irrigation device provided by the utility model overcomes the problem that the water flow of large-volume concrete maintenance is quickly lost from the foundation surface and fails to meet the maintenance requirements, and breaks through the dilemma of large-volume concrete foundation maintenance water resources being wasted during maintenance. The humidity sensor accurately determines the surface humidity of the large-volume concrete foundation, and the controller in the control cabinet analyzes and compares the data, accurately applies water to the large-volume concrete for maintenance, ensuring that the large-volume concrete foundation is maintained within the standard humidity range in real time, and pioneering intelligent maintenance and specialized device maintenance.

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-2 As shown: a drip irrigation device for mass concrete foundation maintenance, the drip irrigation device includes a photovoltaic solar panel 1, an inverter 2, a battery pack 3, a control cabinet 4, a water tank 5, a submersible pump 6, a filter 7, a pressure gauge 8, a solenoid valve 9, a water supply main 10, a vertical weight hanging ring 11, a humidity sensor 12, a water supply branch pipe 13, and a breathable tarpaulin 14. The photovoltaic solar panel 1 stores the converted electrical energy in the battery pack 3 through the inverter 2, and the battery pack 3 supplies power to the control cabinet 4, the submersible pump 6 and the solenoid valve 9; the humidity sensor 12 monitors the mass concrete When the soil foundation needs drip water maintenance, the signal is transmitted to the control cabinet 4, and the control cabinet 4 issues a work instruction for the submersible pump 6 to work and the solenoid valve 9 to open. The submersible pump 6 starts to work, and the maintenance water in the water tank 6 passes through the water supply main 10 and the filter 7 and solenoid valve 9 thereon, the water supply branch pipe 13, and drips the large-volume concrete foundation through the drip holes on the water supply branch pipe 13; the pressure gauge 8 monitors the water pressure of the water supply main 10 in real time and feeds back the pressure information to the control cabinet 6, and the submersible pump 6 is shut down by powering off the control cabinet 4 when the solenoid valve 9 is not opened. At the same time, a layer of breathable tarpaulin 14 is covered on the large-volume concrete foundation, and vertical weight hanging rings 11 are set at the four corners and / or four sides of the tarpaulin 14 to tightly cover the water supply branch pipe 13 above the large-volume concrete foundation.

[0031] Furthermore, the electric energy stored in the battery pack 3 comes from the combined effect of the photovoltaic solar panel 1 and the inverter 2, thereby ensuring the functional requirements of the entire drip irrigation device. The battery pack 3 stores electricity when the electric energy is sufficient during the day to ensure that the drip irrigation device is powered at night. Since the large-volume concrete foundation is maintained under the cover of the breathable tarpaulin 14, the water dissipates slowly, so the humidity value monitored by the humidity sensor 12 will remain within the prescribed maintenance humidity range for a long time, that is, the time for the control cabinet 4 to start the submersible pump 6 through the signal will be shorter. At the same time, in order to avoid the humidity sensor 12 detecting the curing water just flowing out of the drip hole of the water supply branch pipe 13, judging that the humidity is qualified, and transmitting the qualified humidity signal back to the control cabinet 4, causing the control cabinet 4 to send a signal to cause the submersible pump 6 and the solenoid valve 9 to malfunction, the humidity signal monitored by the humidity sensor 12 is only used as the start signal of the submersible pump 6, not as the shutdown signal; the shutdown signal of the submersible pump 6 is set in the logic judgment module of the control cabinet 4. Under normal working conditions, the submersible pump 6 can set the continuous working time of the submersible pump according to the curing process and curing degree of the large-volume concrete foundation. The continuous working time that can be set is 1min, 2min, 3min, 4min, 5min, 8min, and 10min. The application of these functions realizes the continuous use of the drip irrigation device under different weather conditions, enumerates and solves the logical conflicts that may exist in the use of the maintenance drip irrigation device of the utility model, and greatly improves the universality of the maintenance drip irrigation device of the utility model for the curing of large-volume concrete. It can meet the curing requirements under technical standards for large-volume concrete foundations with different shapes and different weather environments.

[0032] In order to facilitate the disassembly of the drip irrigation device for mass concrete foundation maintenance, the control cabinet 4 forms the hub of the entire drip irrigation device. The battery pack 3 is connected to the control cabinet 4 through circuit connection. At the same time, the control cabinet 4 forms a signal transmission and control loop through the circuit and the signal line. The water supply main pipe 10 and the water supply branch pipe 13 are connected by threads. The water supply branch pipes 13 cross each other in a cross shape, and drip holes are opened on the water supply branch pipes 13.

[0033] Furthermore, the above-mentioned control cabinet 4 is connected to the battery pack 3. On the one hand, the battery pack 3 supplies energy to the components and working modules in the control cabinet 4. On the other hand, it is divided in the control cabinet 4 in the form of electrical circuit output lines, one way is connected to the submersible pump 6 in the water tank 5 to complete the control function of the submersible pump 6, and the other way is connected to the solenoid valve 9 through the relay. During operation, the control cabinet 4 issues an action command, and the relay in the control cabinet 4 is actuated after receiving the command, and the energy supply to the submersible pump 6 is connected. The submersible pump 6 starts working and flows the maintenance water in the water tank 5 into the water supply main 10; the solenoid valve 9 also operates synchronously, and another power supply of the control cabinet 4 is connected to the solenoid valve 9 through the relay. When the action command to start the submersible pump 6 is issued, the command to open the solenoid valve 9 is also issued synchronously in the control cabinet 5. After the signal current flows through the corresponding relay, the relay is actuated to make the electrical circuit connected to the solenoid valve 9 conductive, and the solenoid valve 9 is energized and actuated, and the valve of the solenoid valve 9 is opened synchronously, opening a channel for the maintenance water flow drawn from the water tank 5 by the submersible pump 6, so that the maintenance water can smoothly pass through the water supply main 10 and the water supply branch pipe 13.

[0034] In terms of logic control, in order to avoid component failure or control logic errors during operation, we have made the following enumerations and provided corresponding solutions one after another.

[0035] First, after the control cabinet 4 issues an action command, the submersible pump 6 does not start, or the maintenance water in the water tank 5 is completely exhausted, resulting in the submersible pump 6 starting empty. At this time, the pressure gauge 8 located on the water supply main 10 will detect that the water pressure of the water supply main 10 is 0, and transmit the water pressure signal to the control cabinet 4 through the sensor. After obtaining such a pressure signal, the control cabinet 4 analyzes and determines that it may be due to the submersible pump 6 not working or the water in the water tank 5 being exhausted. The control cabinet 4 then issues a shut-down current signal, so that the submersible pump 6 loses power and does not operate, and the solenoid valve 9 changes from the original open state to the closed state, and the first fault indicator light of the control cabinet 4 will be always on to indicate that the maintenance drip irrigation device provided by the utility model has a fault.

[0036] Second, the control cabinet 4 issues an action command, and the relays of the submersible pump 6 and the electromagnetic valve 9 are energized at the same time, so that the submersible pump 6 starts working, but the electromagnetic valve 9 is not opened and locked. At this time, due to the operation of the submersible pump 6, the water in the water tank 5 is pumped to the node position where the electromagnetic valve 9 is installed on the water supply main 10. At this time, the water column forms a blocked state in the water supply main 10, and the pressure of the pressure gauge 8 on the water supply main 10 continues to increase. The pressure sensor on the pressure gauge 8 detects an abnormally large pressure value and immediately transmits it to the control cabinet 4. After analysis by the control cabinet 4, it is determined that the electromagnetic valve 9 is faulty, and the control cabinet 4 sends a shut-down current signal, so that the submersible pump 6 loses power and does not operate, and the electromagnetic valve 9 does not operate from the original closed state, and the second fault indicator light of the control cabinet 4 is always on, to indicate that the maintenance drip irrigation device provided by the utility model has a fault.

[0037] Third, when the maintenance water flows out to the surface of the large-volume concrete foundation through the drip holes on the water supply branch pipe 13, the humidity sensor 12 arranged on the surface of the concrete foundation will immediately monitor the humidity value at this time. Since the water flows on the concrete surface area during drip irrigation, the humidity is high. After the humidity sensor 12 transmits the humidity value at this time to the control cabinet 4, the analysis module will definitely analyze that the humidity is qualified. In fact, shortly after this set of maintenance drip irrigation device was put into operation. In order to avoid the situation that the control cabinet 4 sends a signal to shut down the submersible pump 6 and the solenoid valve 9 due to differences in actual maintenance conditions, this set of drip irrigation maintenance device introduces maintenance time setting. Maintenance personnel can set different drip irrigation times according to the different water requirements of the large-volume concrete foundation during the entire maintenance process. For example, in the early stage of maintenance of the large-volume concrete foundation, the maintenance water demand is large, and a longer drip irrigation time can be set to ensure that the large-volume concrete foundation is fully watered; in the later stage of maintenance of the large-volume concrete foundation, the maintenance water demand is small, and a shorter drip irrigation time can be set to ensure that water resources are not wasted in large quantities. This will enable economical, environmentally friendly and green large-volume concrete foundation maintenance operations.

[0038] When the large-volume concrete foundation maintenance drip irrigation device of the utility model is used, the control switch in the control cabinet 4 is started to start the maintenance drip irrigation device, and the control cabinet 4 receives the humidity signal on the surface of the large-volume concrete foundation from the humidity sensor 12 for analysis and judgment. When the control cabinet 4 determines that the humidity of the concrete surface is within the prescribed range of the maintenance humidity, no action is taken; when the control cabinet determines that the humidity of the concrete surface is not within the prescribed range of the maintenance humidity and maintenance is required, the action signal of the submersible pump 6 and the action signal of the solenoid valve 9 are synchronously sent out, so that the submersible pump 6 is powered on and started, and the solenoid valve 9 receives the signal to control the valve to open, and the maintenance water in the water tank 5 is passed through The water supply main pipe 10 and the water supply branch pipe 13, the drip holes on the water supply branch pipe 13 drip the maintenance water onto the surface of the large-volume concrete foundation, so that the large-volume concrete foundation can be maintained with water; the photovoltaic solar panel 1 converts light energy into electrical energy after receiving it, and stores the generated electrical energy in the battery pack 3 through the inverter 2. The battery pack 3 is connected to the terminal block in the control cabinet 4 through the line, and the power supply is connected to the submersible pump 6 and the solenoid valve 9 respectively through the control cabinet 4 branch line. At the same time, the receiving signal module in the control cabinet 4 can receive the water pressure signal from the pressure gauge 8 to monitor the water supply main pipe 10 in real time and the humidity sensor 12 to monitor the humidity signal of the large-volume concrete surface in real time, and can store and analyze it.

[0039] When the large-volume concrete foundation maintenance drip irrigation device of the utility model is used, the pressure gauge 8 can monitor the water pressure signal of the water supply main 10 in real time and transmit the signal value to the model acquisition module in the control cabinet 4; when the maintenance drip irrigation device is not performing drip irrigation, the submersible pump 6 is not in operation, the water supply main 10 has no water pressure, and the solenoid valve 9 is in a closed state. At this time, the control cabinet 4 monitors that the pressure signal is 0, and it is determined that the maintenance drip irrigation device is not in operation; when the maintenance drip irrigation device is in operation, the submersible pump 6 is started, and the solenoid valve 9 is synchronously started to open the valve, and the submersible pump 6 pumps out the water in the water tank 5, and completes the maintenance water supply to the large-volume concrete foundation through the pipeline; when any of the water supply branch pipe 13, the water supply main 10 or the solenoid valve 9 fails, the water pressure monitored by the pressure gauge 8 will increase sharply. At this time, the water pressure signal is transmitted to the control cabinet 4, and it is determined that the maintenance drip irrigation device has a special situation. The control cabinet 4 will immediately act to shut down the submersible pump 6, so that the maintenance drip irrigation device stops working.

[0040] Compared with the machines on the market, the large-volume concrete foundation maintenance drip irrigation device of the utility model overcomes the problem that the water flow of the large-volume concrete water curing quickly flows away from the foundation surface and fails to meet the maintenance requirements, and breaks through the dilemma of large-volume concrete foundation maintenance water resources being wasted during the maintenance period. Through the humidity sensor 12, the humidity of the large-volume concrete foundation surface is accurately determined, and the controller analyzes and compares the data, and accurately applies water to the large-volume concrete for maintenance, ensuring that the large-volume concrete foundation is maintained in the standard humidity range in real time, opening up intelligent maintenance and specialized device maintenance. The future maintenance direction based on automatic control reduces the labor cost caused by timely watering maintenance in the maintenance of large-volume concrete foundations, improves the technical support for concrete foundation maintenance, and provides a specialized maintenance device for the maintenance of large-volume concrete foundations of power equipment. It solves a series of problems in the maintenance of large-volume concrete foundations of traditional power equipment, which requires manual maintenance at irregular intervals and wastes a lot of water resources, such as low efficiency, uneconomical, high labor intensity, and large waste of water resources. On the basis of realizing the maintenance of large-volume concrete foundations, it expands the area of ​​saving water resources, automatic control, reducing labor intensity and economic profitability. It has the characteristics of reasonable design and easy use, broad practical application prospects, and is suitable for popularization and use.

[0041] The above embodiments are only for illustrating the technical idea of ​​the utility model, and cannot be used to limit the protection scope of the utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the utility model shall fall within the protection scope of the utility model; any technology not involved in the utility model can be realized by existing technology.
