Technical Field

[0001] The utility model belongs to the technical field of drip irrigation, and particularly relates to an intelligent drip irrigation device based on the Internet of Things. Background Art

[0002] Drip irrigation technology is a water-saving irrigation technology. By accurately aligning the water outlet of the drip irrigation device with the root of the plant, the water dripped by the drip irrigation device can be effectively absorbed by the plant, thereby avoiding the waste of excess water due to evaporation. With the development and progress of technology, the Internet of Things is more and more widely used in production and life. Now, drip irrigation devices can also be remotely controlled and started through the Internet of Things, and irrigation can be carried out on crops without manually controlling the water gate switch, which greatly improves the convenience of using drip irrigation devices.

[0003] Although the existing drip irrigation devices can be started by remote control, improving convenience, the amount of water dripped by the drip irrigation devices in the prior art is usually fixed. The controller usually only remotely controls the drip irrigation device to carry out drip irrigation on time, but cannot real-time monitor the environment where the drip irrigation device is located, so the amount of water dripped by the drip irrigation device cannot be adjusted appropriately. In this way, the amount of drip irrigation is often too much or too little, which is not conducive to the growth of crops.

[0004] Therefore, an intelligent drip irrigation device based on the Internet of Things is proposed, which can automatically adjust the amount of drip irrigation according to the environment where it is located. Content of the Utility Model

[0005] The purpose of the utility model is to provide an intelligent drip irrigation device based on the Internet of Things, so as to overcome the problem that the drip irrigation device in the prior art cannot automatically adjust the amount of drip irrigation according to the environment.

[0006] The specific technical solution is as follows:

[0007] An intelligent drip irrigation device based on the Internet of Things includes a housing, a connecting pipe port and a liquid dripping port. The connecting pipe port is used to connect with the water supply pipeline controlled by the Internet of Things. The liquid dripping port is located below the housing, and the liquid dripping port is communicated with the connecting pipe port for dripping liquid to irrigate crops. A regulating plate is vertically arranged inside the liquid dripping port. The bottom of the regulating plate is horizontally bent to form a shielding part for hindering the liquid from flowing into the liquid dripping port. The regulating plate is made of a two-way shape memory metal. After the regulating plate is heated, the shielding part becomes a vertical state.

[0008] Preferably, the shell is also provided with a baffle rod which is vertically slidable, one end of the baffle rod extends into the interior of the shell, and the other end is located outside the shell, the baffle rod is vertically aligned with the drip port, the diameter of the baffle rod is the same as the diameter of the drip port, and a tray is provided at one end of the baffle rod located outside the shell, a water-absorbing sponge is fixedly mounted on the tray, a return spring is wound around the baffle rod, the return spring is used to lift the tray upward, and the top of the adjustment plate is fixedly connected to the bottom of the baffle rod.

[0009] Preferably, a liquid storage cavity is provided inside the shell, and the liquid storage cavity is connected with the pipe connection port and the dripping port.

[0010] Preferably, a U-shaped cover is provided on the top of the shell, the opening of the U-shaped cover faces upward, and the tray and the sponge are both located in the U-shaped cover.

[0011] Preferably, a plurality of drainage ports are provided at the bottom of the U-shaped cover.

[0012] Preferably, an inclined guide portion is provided on the shell, and the guide portion is located below the drain outlet.

[0014] Preferably, the baffle rod is made of hollow metal, a heat conductive sheet is arranged on the top of the water absorbent sponge, the heat conductive sheet is made of metal, the area of ​​the heat conductive sheet is smaller than the area of ​​the water absorbent sponge, and the top of the baffle rod passes through the tray and the water absorbent sponge and is fixedly connected to the heat conductive sheet.

[0015] Compared with the existing technology, the beneficial effects of the utility model are:

[0016] 1. The utility model is a smart drip irrigation device based on the Internet of Things. By setting an adjustment plate made of a two-way memory metal at the drip port, the shape of the adjustment plate is automatically adjusted according to the weather temperature, and then the amount of drip irrigation is automatically adjusted according to the weather temperature. In hot weather, more water can drip from the drip port to irrigate crops, while in cold weather, the amount of drip irrigation for crops is reduced, making more rational use of water resources.

[0017] 2. The utility model is designed to be an intelligent drip irrigation device based on the Internet of Things, which is also provided with a flow-blocking rod and a water-absorbing sponge. The water-absorbing sponge cooperates with the flow-blocking rod to automatically detect whether it is raining in the environment. If it rains in the environment where the drip irrigation device is located, the rainwater will be collected by the water-absorbing sponge and the weight of the water-absorbing sponge will be increased. The water-absorbing sponge will drive the flow-blocking rod to move toward the direction of the dripping port and reduce the dripping port, thereby avoiding the drip irrigation device from wasting water resources when it rains.

DETAILED DESCRIPTION

[0027] The following is a further detailed description of the embodiments of the invention in conjunction with the accompanying drawings to make the objectives, technical solutions and technical effects of the invention more clearly presented.

[0028] refer to Figures 1 to 8 , an intelligent drip irrigation device based on the Internet of Things, comprising a shell 1, a pipe connection port 2 and a dripping port 3, the pipe connection port 2 is used to be connected to a water supply pipeline controlled by the Internet of Things, the dripping port 3 is located below the shell 1, the dripping port 3 is connected to the pipe connection port 2 and is used to drip liquid to irrigate crops; an adjusting plate 4 is vertically arranged inside the dripping port 3, the bottom of the adjusting plate 4 is horizontally bent to form a shielding portion 5 for preventing liquid from flowing into the dripping port 3, the adjusting plate 4 is made of a two-way memory metal, and after the adjusting plate 4 is heated, the shielding portion 5 becomes a vertical state.

[0029] refer to Figure 5 , Figure 6 and Figure 7, the memory temperature of the two-way shape memory alloy can be selected within the temperature range of 30°C to 50°C. When the ambient temperature of the adjusting plate 4 made of shape memory alloy is below the memory temperature, the bottom of the adjusting plate 4 is in a horizontal bending state. The bottom of the adjusting plate 4 bends to the horizontal position to form a shielding portion 5, and the shielding portion 5 shields the liquid dripping port 3, and the shielding area is half of the area of the liquid dripping port 3. When the ambient temperature of the adjusting plate 4 is higher than the memory temperature, the shielding portion 5 at the bottom of the adjusting plate 4 returns to the vertical state as the upper side of the adjusting plate 4, and the shielding of the liquid dripping port 3 by the shielding portion 5 is lost. The speed of the liquid flowing through the liquid dripping port 3 will increase, and the amount of drip irrigation for the crop within the same time will be greater.

[0030] Reference Figure 6 and Figure 7 , usually, the time length for the drip irrigation device to supply water for crop drip irrigation is the same. Through the above setting of the adjusting plate 4, the drip irrigation device can drip irrigate at a fixed rate when the ambient temperature is lower than the memory temperature of the adjusting plate 4, which can not only meet the drip irrigation requirements of the crop but also avoid wasting water resources. When the ambient temperature continuously rises and exceeds the memory temperature of the adjusting plate 4, it indicates that the drought degree of the environment is more serious, and at this time, the crop's water demand will be greater. At this time, the adjusting plate 4 automatically deforms to increase the rate of the liquid dripping from the liquid dripping port 3, and the crop can obtain more water within the same drip irrigation time, so as to ensure that the crop has enough water for its growth.

[0031] Reference Figure 2 and Figure 5 , a flow blocking rod 6 is vertically slidably arranged on the outer shell 1. One end of the flow blocking rod 6 extends into the interior of the outer shell 1, and the other end is located outside the outer shell 1. The flow blocking rod 6 is vertically aligned with the liquid dripping port 3, and the diameter of the flow blocking rod 6 is the same as the diameter of the liquid dripping port 3. A tray 7 is arranged at one end of the flow blocking rod 6 located outside the outer shell 1. A water-absorbing sponge 8 is fixedly installed on the tray 7. A return spring 10 is wound around the flow blocking rod 6, and the return spring 10 is used to push the tray 7 upward. The top end of the adjusting plate 4 is fixedly connected to the bottom of the flow blocking rod 6.

[0032] Reference Figure 5 and Figure 8, the water-absorbing sponge 8 is used to detect whether it is raining in the environment where the drip irrigation device is located or whether it has rained recently. If it has rained in the environment where the irrigation device is located, the rainwater will be absorbed by the water-absorbing sponge 8. After the water-absorbing sponge 8 absorbs the rainwater, its weight will increase. Under its own gravity, the water-absorbing sponge 8 will drive the flow-blocking rod 6 to move downward. At this time, the return spring 10 begins to be compressed under force. After the flow-blocking rod 6 moves downward, the end face of the flow-blocking rod 6 will get closer and closer to the port of the liquid dripping port 3. The flow-blocking rod 6 will reduce the rate at which the liquid flows to the liquid dripping port 3, reduce the drip irrigation efficiency of the liquid dripping port 3, avoid over-irrigating the crops after rain and causing damage to the crops, and at the same time can save water and avoid waste. If the rainwater absorbed by the water-absorbing sponge 8 is enough, the bottom end of the flow-blocking rod 6 will directly extend into the liquid dripping port 3 to directly close the liquid dripping port 3. At this time, even if the connection port 2 supplies water to the liquid dripping port 3, no water droplets will drip out at the liquid dripping port 3. It is worth mentioning that in the case of rain, even if the environmental temperature becomes higher and the shielding part 5 on the adjusting plate 4 becomes vertical, the liquid dripping port 3 will also be affected by the flow-blocking rod 6 and the liquid dripping amount will be reduced, that is, the priority of the flow-blocking rod 6 to adjust the liquid dripping port 3 is higher than the priority of the adjusting plate 4 to adjust the liquid dripping port 3, ensuring that the crops will not be over-irrigated.

[0033] After the sky clears, as the water inside the water-absorbing sponge 8 is evaporated, the mass of the water-absorbing sponge 8 will become lighter and lighter. Under the action of its own elastic force, the return spring 10 drives the water-absorbing sponge 8 and the flow-blocking rod 6 to move upward. As the water inside the sponge is evaporated, the flow efficiency of the liquid dripping port 3 will also be restored accordingly, ensuring that after the sky clears and the rainwater is evaporated, the crops can have enough water sources for growth.

[0034] Reference Figure 5 , a liquid storage cavity 9 is arranged inside the outer shell 1. The liquid storage cavity 9 communicates with the connection port 2 and the liquid dripping port 3. When it rains, if the rain is heavy enough or lasts long enough, when the water-absorbing sponge 8 absorbs the rainwater and drives the flow-blocking rod 6 to move downward to block the liquid dripping port 3, at this time, if the connection port 2 supplies water to the liquid dripping port 3 regularly, the water supplied by the connection port 2 to the liquid dripping port 3 will be temporarily stored in the liquid storage cavity 9 first. When the water inside the water-absorbing sponge 8 is evaporated and the return spring 10 drives the flow-blocking rod 6 to gradually move upward, it means that the moisture in the land where the crops are planted is also gradually evaporated. When the flow-blocking rod 6 is gradually lifted upward, when the liquid dripping port 3 is opened again, the water inside the liquid storage cavity 9 will flow downward from the liquid dripping port 3 and drip onto the land at the root of the crops, and the dripping speed will increase as the evaporation speed of the water inside the water-absorbing sponge 8 increases. It will neither over-supply water to damage the growth of the crops nor can continuously supply water effectively to the crops for the growth needs of the crops.

[0035] Reference Figures 1 to 5, a U-shaped cover 11 is provided at the top of the outer shell 1. The opening of the U-shaped cover 11 faces upward, and both the tray 7 and the sponge are located inside the U-shaped cover 11. After the U-shaped cover 11 surrounds the water-absorbing sponge 8 and the release plate, it avoids the situation where the water-absorbing sponge 8 is knocked off the tray 7 by sundries, ensuring that the device can stably detect rainwater automatically and adjust the dripping speed of the dripping port 3 automatically. It improves the stability and service life of the device during operation. The upward opening of the U-shaped cover 11 can ensure that the water-absorbing sponge 8 can absorb rainwater immediately when it rains.

[0036] Reference Figure 5 , a plurality of drain ports 12 are provided at the bottom of the U-shaped cover 11. The drain ports 12 prevent rainwater from accumulating inside the U-shaped cover 11 during rain, avoid the reset spring 10 from rusting and aging due to long-term soaking in rainwater, and improve the service life of the device. In addition, it can also prevent rainwater from occupying the space between the tray 7 and the bottom of the U-shaped cover 11 and hindering the downward movement of the tray 7, ensuring that the flow-blocking effect of the flow-blocking rod 6 on the dripping port 3 can take effect stably, and improving the use stability of the device.

[0037] Reference Figure 3 and Figure 5 , an inclined diversion part 13 is provided on the outer shell 1. The diversion part 13 is located below the drain port 12. The diversion part 13 diverts the rainwater discharged from the drain port 12 around the outer shell 1, so that the rainwater discharged from the drain port 12 can flow down the side wall of the outer shell 1 to irrigate the land below, avoiding the rainwater discharged from the drain port 12 from accumulating on the outer shell 1 and being directly evaporated by the sun and wasted. It helps to further improve the irrigation effect on crops and avoid waste of water resources.

[0038] Reference Figure 5 , the tray 7 is made of plastic. Compared with being made of metal, the plastic tray 7 is cheaper and lighter in weight, which helps to reduce the difficulty of resetting the reset spring 10 and improve the reaction sensitivity of the flow-blocking rod 6.

[0039] Reference Figure 5 , the flow-blocking rod 6 is made of hollow metal. A heat-conducting sheet 14 is provided at the top of the water-absorbing sponge 8. The heat-conducting sheet 14 is made of metal, and the area of the heat-conducting sheet 14 is smaller than the area of the water-absorbing sponge 8. The top of the flow-blocking rod 6 penetrates through the tray 7 and the water-absorbing sponge 8 and is fixedly connected to the heat-conducting sheet 14 by welding or by bolt connection. When the heat-conducting sheet 14 is fixedly connected to the flow-blocking rod 6, it is ensured that the heat-conducting sheet 14 is in direct contact with the flow-blocking rod 6, ensuring good heat conduction between the heat-conducting sheet 14 and the flow-blocking rod 6.

[0040] The choke rod 6 made of hollow metal can further improve the response sensitivity of the return spring 10. The heat conducting sheet 14 is arranged on the top of the water absorption sponge 8 to more intuitively sense the ambient temperature. Subsequently, the heat conducting sheet 14 conducts the temperature to the choke rod 6 and the adjusting plate 4, enabling the adjusting plate 4 to better detect the ambient temperature and making the adjusting plate 4 more sensitive to the ambient temperature, improving the response speed of the device, and thus enhancing the usage effect of the device. In addition, the heat conducting sheet 14 is located on the top of the water absorption sponge 8, which can also effectively prevent the situation where the water absorption effect of the water absorption sponge 8 decreases due to debris squeezing the water absorption sponge 8 after the debris falls on the top of the water absorption sponge 8, improving the usage stability of the device.

Any equivalent changes, equivalent substitutions or modified changes completed within the technical spirit and principles disclosed by the present invention shall be included within the scope of patent protection covered by the present invention.
