Description

Technical Field

[0001] The invention belongs to the technical field of farmland sprinkler irrigation, and in particular relates to rice field spraying equipment, a temperature monitoring system and a method. Background Art

[0002] Dry land generally refers to arable land without irrigation facilities, which mainly relies on natural precipitation to grow drought-tolerant crops, including arable land without irrigation facilities and only relies on flood diversion and irrigation. Among my country's grain crops, crops such as dry rice and wheat can be grown in dry land. In modern agriculture, vertical pipes are often used for irrigation of dry land. At the same time, the existing vertical pipe sprinkler irrigation equipment is equipped with a rotating head on the top of the vertical pipe. At the same time, the same-direction oblique nozzles arranged on the rotating head can use the sprinkler power of the high-pressure water source to drive the rotating head to rotate, thereby realizing rotary sprinkler irrigation.

[0003] However, the nozzles of existing sprinkler irrigation equipment are mostly fixed, and the area of ​​sprinkler irrigation is limited. At the same time, rice crops near the riser cannot be effectively sprinkler irrigated. In addition, in an extremely dry and hot weather environment, only sprinkler irrigation of rice crops cannot change the temperature and humidity of the environment, which is not conducive to the growth of rice crops. For this reason, we propose a rice field spray equipment, a temperature monitoring system and a method to solve the problems existing in the prior art. Summary of the invention

[0009] The transverse connecting pipe is processed with a connected driving shell, and the driving shell is located between the second rotating drum and the first nozzle. The swing assembly includes a first water wheel, a turntable and a telescopic rod. The rotating shaft of the first water wheel is rotatably connected to the driving shell, and the blades of the first water wheel are not fixed to the inner wall of the driving shell.

The end of the second nozzle is installed and fixed to the telescopic rod. The movable end of the telescopic rod is provided with a hinge seat, and the hinge seat is rotatably hinged to the turntable.

[0010] The first connection part and the second connection part are rotatably nested, and the rotating assembly includes a second water wheel, and the blades of the second water wheel are fixed to the inner wall of the second connection part.

[0011] The locking assembly includes an annular electromagnet and an annular iron sheet for magnetic attraction. The annular electromagnet is sleeved and fixed on the outer wall surface of the first connecting part, and the annular iron sheet is installed on the outer wall surface of the second connecting part. The annular iron sheet corresponds to and matches the annular electromagnet.

[0012] A mounting frame is provided on the upper side of the water collecting cylinder, and a control box is installed on the mounting frame. The control box has a power storage module and a controller module built in. The power storage module is electrically connected to the controller module, and the power storage module is electrically connected to the first electrically controlled valve, the second electrically controlled valve and the annular electromagnet respectively.

[0013] The upper side of the vertical pipe is a partition structure, the first rotating drum is rotatably connected to the partition of the vertical pipe, and the partition of the vertical pipe is connected as a whole through a plurality of first connecting ribs arranged on the inner wall of the vertical pipe;

[0014] The side of the transverse connecting pipe close to the second connecting part is a partition structure, the second rotating drum is rotatably connected to the partition of the transverse connecting pipe, and the partition of the transverse connecting pipe is connected as a whole through a plurality of second connecting ribs arranged on the inner wall of the transverse connecting pipe.

[0015] It also includes a temperature detection system, which includes a temperature sensor and a humidity sensor. The power storage module is electrically connected to the temperature sensor and the humidity sensor, and the temperature sensor and the humidity sensor are both signal-connected to the controller module.

[0016] The present invention also provides a rice field spraying method, which includes the following spraying modes:

[0017] ①Irrigation mode (normal mode):

[0018] The controller module locks and fixes the first connection part and the second connection part through the locking component, and the first connection part and the second connection part no longer rotate, closes the first electrically controlled valve of the transverse connecting pipe and opens the second electrically controlled valve of the water inlet branch pipe, and water enters the transverse connecting pipe through the vertical pipe and the water inlet branch pipe, but does not enter the transverse connecting pipe through the vertical pipe, the water collecting cylinder, the first connection part and the second connection part.

At the same time, the second nozzle is swung by the swing component, and the water sprayed by the second nozzle irrigates the rice field crops far from the vertical pipe in a large range, thereby increasing the irrigation range and keeping the rice field crops in a suitable moisture and temperature environment by means of water spray irrigation;

[0019] ②Cooling and humidifying mode (extreme weather mode):

[0020] When the temperature sensor detects that the outside atmospheric temperature is greater than the high temperature threshold, and the humidity sensor detects that the air humidity is higher than the humidity threshold in an extremely hot environment, the controller module loosens and fixes the first connection part and the second connection part through the locking assembly, and the first connection part and the second connection part can rotate, opening the first electrically controlled valve of the transverse connecting pipe and closing the second electrically controlled valve of the water inlet branch pipe, and water enters the transverse connecting pipe through the vertical pipe, the water collecting cylinder, the first connection part and the second connection part, but does not enter the transverse connecting pipe through the vertical pipe and the water inlet branch pipe. At this time, after the water passes through the rotating assembly and the swinging assembly, the horizontally pulled connecting pipe revolves around the vertical pipe and can also rotate by itself. The water sprayed by the first nozzle due to the periodic change in direction causes the transverse connecting pipe to reciprocate relative to the vertical pipe, so that the water sprayed by the first nozzle and the second nozzle can not only irrigate the paddy crops around the vertical pipe in a large range, but also spray water into the upper air to cool down and increase the air humidity under the rotation of the second connection part, so as to keep the paddy crops in a suitable moisture and temperature environment.

[0021] The present invention can comprehensively irrigate the rice field crops around the vertical pipe through the first nozzle and the second nozzle, and can irrigate a farther range through the swinging second nozzle, thereby expanding the irrigation area, and can change the direction of water flow to change the irrigation method, so that not only normal irrigation operations can be carried out, but also the temperature and humidity of the upper air around the vertical pipe can be improved.

[0038] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0039] Embodiment 1, as Figures 1 to 5 A rice field spraying device shown in the figure comprises a vertical pipe 100, a water collecting cylinder 101 rotatably connected to the upper end of the vertical pipe 100, a plurality of first connecting parts 110 arranged on the side of the water collecting cylinder 101, and a plurality of spraying mechanisms transversely connected to the first connecting part 110, the spraying mechanism comprises a second connecting part 120, a transverse connecting pipe 130, a first nozzle 140 and a second nozzle 150, the second connecting part 120 is rotatably connected to the first connecting part 110, the transverse connecting pipe 130 is transversely connected to the second connecting part 120, the first nozzle 140 is vertically installed at the rear end of the transverse connecting pipe 130 and the first nozzle 140 is obliquely arranged downward, the rear end of the transverse connecting pipe 130 is also equipped with a rotating joint 131 vertically arranged in the horizontal direction, and the second nozzle 150 is connected to the rotating joint 131;

[0040] A first rotary drum 102 is sleeved on the upper side of the vertical pipe 100, a second rotary drum 132 is arranged on one side of the transverse connecting pipe 130 close to the second connecting portion 120, a first electrically controlled valve 133 is installed on the transverse connecting pipe 130, and the first electrically controlled valve 133 is located between the second connecting portion 120 and the second rotary drum 132, a water inlet branch pipe 134 is commonly connected between the first rotary drum 102 and the second rotary drum 132, and a second electrically controlled valve 135 is installed on the water inlet branch pipe 134;

[0041] The transverse connecting pipe 130 and the second nozzle 150 are jointly provided with a swinging assembly, which utilizes water flow to drive the second nozzle 150 to swing. The second connecting part 120 is provided with a rotating assembly, which utilizes water flow to drive the second connecting part 120 to rotate. A locking assembly is also provided between the first connecting part 110 and the second connecting part 120, and the locking assembly utilizes electromagnetic attraction to fix and loosen the first connecting part 110 and the second connecting part 120.

[0042] Before use, fix the standpipe 100 to the dry ground through ground nails, and connect the external high-pressure water source to the standpipe 100, and then it can be used;

[0043] When using it, there are two ways:

[0044] ① The first electrically controlled valve 133 is closed and the second electrically controlled valve 135 is opened. At the same time, the locking assembly fixes the first connection part 110 and the second connection part 120. The high-pressure water source enters the water inlet branch pipe 134 from the vertical pipe 100 and is then introduced through the horizontal connection pipe 130. The high-pressure water source will not enter the second connection part 120. Therefore, the rotating assembly will not cause the second connection part 120 to rotate. Finally, the high-pressure water mist is sprayed out through the first nozzle 140 and the second nozzle 150.

[0045] In this manner, since the first nozzle 140 is vertically mounted on the rear end of the transverse connecting pipe 130 and is obliquely arranged downward, when the first nozzle 140 sprays high-pressure water mist, each transverse connecting pipe 130 can drive the first connecting part 110, the second connecting part 120 and the water collecting cylinder 101 to rotate unidirectionally relative to the vertical pipe 100, and at the same time, the water inlet branch pipe 134 is connected to the vertical pipe 100 through the first rotating drum 102, so the water inlet branch pipe 134 can also rotate relative to the vertical pipe 100 without interfering with the rotation of the transverse connecting pipe 130, so that the water mist sprayed downward by the first nozzle 140 can irrigate the rice field crops near the vertical pipe 100, and at the same time, under the action of the water flow inside the transverse connecting pipe 130, the second nozzle 150 connected by the rotating joint 131 swings up and down through the swing component, so that the high-pressure water mist sprayed by the second nozzle 150 can increase the irrigation area and irrigate the rice field crops far away from the vertical pipe 100;

[0046] ② The first electrically controlled valve 133 is opened and the second electrically controlled valve 135 is closed. At the same time, the locking assembly releases the first connection part 110 and the second connection part 120. The water source enters the water collecting cylinder 101 from the vertical pipe 100, and is then introduced through the first connection part 110, the second connection part 120 and the horizontal connection pipe 130. Finally, the high-pressure water mist is sprayed out through the first nozzle 140 and the second nozzle 150.

[0047] In this mode, unlike the first mode, the water flow first passes through the rotating assembly of the second connecting part 120 and then passes through the swinging assembly. Therefore, the transverse connecting pipe 130 not only revolves around the vertical pipe 100, but the second connecting part 120 rotates automatically under the transmission of the rotating assembly and also drives the transverse connecting pipe 130 to rotate automatically. In this way, the first nozzle 140 will not only spray downward, but also rotate to spray, and can spray high-pressure water mist into the upper air. In addition, under the self-rotation of the first nozzle 140, the direction of the sprayed high-pressure water mist changes periodically, so that the transverse connecting pipe 130 drives the first connecting part 110 and the second connecting part 120 to rotate automatically. The connecting portion 120 and the water collecting cylinder 101 reciprocate and rotate relative to the vertical pipe 100. At the same time, since the water inlet branch pipe 134 is connected to the first rotating drum 102 and the second rotating drum 132, it will not interfere with the revolution of the transverse connecting pipe 130 around the vertical pipe and the self-rotation of the transverse connecting pipe 130. When the transverse connecting pipe 130 self-rotates, the second nozzle 150 that swings up and down will further rotate, so that the second nozzle 150 will also be able to spray high-pressure water mist into the upper air, thereby not only irrigating the rice field crops around the vertical pipe 100, but also improving the temperature and humidity of the upper air around the vertical pipe 100.

[0048] The present invention can comprehensively irrigate the rice field crops around the vertical pipe through the first nozzle and the second nozzle, and can irrigate a farther range through the swinging second nozzle, thereby expanding the irrigation area, and can change the direction of water flow to change the irrigation method, so that not only normal irrigation operations can be carried out, but also the temperature and humidity of the upper air around the vertical pipe can be improved.

[0049] As an illustration of the swing assembly, the rotating assembly and the locking assembly in this embodiment, Figure 3 to Figure 4 As shown, the transverse connecting pipe 130 is processed with a connected driving housing 136, the driving housing 136 is located between the second rotating drum 132 and the first nozzle 140, the swing assembly includes a first water wheel 137, a rotating disk 138 and a telescopic rod 151, the rotating shaft of the first water wheel 137 is rotatably connected to the driving housing 136, the blades of the first water wheel 137 are not fixed to the inner wall of the driving housing 136, the rotating shaft of the first water wheel 137 rotates through the driving housing 136 and the end is fixedly connected to the rotating disk 138, the end of the second nozzle 150 is fixedly installed to the telescopic rod 151, the movable end of the telescopic rod 151 is provided with a hinge seat 152, and the hinge seat 152 is rotatably hinged to the rotating disk 138;

[0050] The first connection part 110 is rotatably nested with the second connection part 120, and the rotating assembly includes a second water wheel 121, and the blades of the second water wheel 121 are fixed to the inner wall of the second connection part 120;

[0051] The locking assembly includes an annular electromagnet 111 and an annular iron sheet 122 for magnetic attraction. The annular electromagnet 111 is sleeved and fixed on the outer wall of the first connecting part 110, and the annular iron sheet 122 is installed on the outer wall of the second connecting part 120. The annular iron sheet 122 corresponds to the annular electromagnet 111.

[0052] The working principle of the swing assembly is as follows:

[0053] When the high-pressure water source enters the transverse connecting pipe 130, the water flow will push the blades of the first water wheel 137 to rotate in the driving housing 136, so that the turntable 138 fixed by the rotating shaft of the first water wheel 137 rotates, and because the end of the second nozzle 150 is rotatably hinged with the turntable 138 through the telescopic rod 151 and the hinge seat 152, when the turntable 138 rotates, the second nozzle 150 will automatically swing by pulling the telescopic rod 151. At the same time, when the turntable 138 rotates, the telescopic rod 151 can also be adaptively extended and retracted to avoid being stuck;

[0054] The working principle of the rotating assembly is as follows:

[0055] When the high-pressure water source enters the first connection part 110 and the second connection part 120, the water flow will drive the blades of the second water wheel 121 fixed inside the second connection part 120 to rotate, so that the second connection part 120 can rotate relative to the first connection part 110, thereby driving the transverse connection pipe 130 to rotate.

[0056] The locking assembly works as follows:

[0057] When the annular electromagnet 111 installed on the outer wall of the first connecting part 110 is energized to generate magnetism, it can magnetically attract the annular iron sheet 122 on the outer wall of the second connecting part 120, thereby fixing the first connecting part 110 and the second connecting part 120. When the annular electromagnet 111 is powered off and demagnetized, the annular electromagnet 111 can release the magnetic attraction with the annular iron sheet 122, and the second connecting part 120 can rotate relative to the first connecting part 110.

[0058] As a further improvement to this embodiment, Figure 1 , Figure 2 as well as Figure 6 As shown, a mounting frame 103 is provided on the upper side of the water collecting cylinder 101, and a control box 104 is installed on the mounting frame 103. The control box 104 has a built-in power storage module and a controller module. The power storage module is electrically connected to the controller module, and the power storage module is electrically connected to the first electric control valve 133, the second electric control valve 135 and the annular electromagnet 111 respectively;

[0059] At the same time, it also includes a temperature detection system, which includes a temperature sensor 160 and a humidity sensor 161. The power storage module is electrically connected to the temperature sensor 160 and the humidity sensor 161, and the temperature sensor 160 and the humidity sensor 161 are both connected to the controller module signal.

[0060] The set temperature sensor 160 and humidity sensor 161 can monitor the air temperature and humidity. The power storage module is directly connected to the temperature sensor 160 and the humidity sensor 161, so that the temperature sensor 160 and the humidity sensor 161 can maintain a working state in real time. At the same time, the controller module controls the circuit between the power storage module and the first electric control valve 133, the second electric control valve 135 and the annular electromagnet 111 through the temperature and humidity information monitored by the temperature sensor 160 and the humidity sensor 161, so as to control the opening and closing of the first solenoid valve 133 and the second solenoid valve 135 and the power on and off of the annular electromagnet 111, so as to change the sprinkler irrigation mode.

[0061] As an illustration of the connection method of the first drum 102 and the second drum 132 in the above embodiment, Figure 3 and Figure 5 As shown, the upper side of the vertical pipe 100 is a partition structure, the first rotating drum 102 is rotatably connected to the partition of the vertical pipe 100, and the partition of the vertical pipe 100 is connected as a whole through a plurality of first connecting ribs 105 arranged on the inner wall of the vertical pipe 100;

[0062] The side of the transverse connecting tube 130 close to the second connecting portion 120 is a partition structure, the second rotating drum 132 is rotatably connected to the partition of the transverse connecting tube 130, and the partition of the transverse connecting tube 130 is connected as a whole through a plurality of second connecting ribs 139 arranged on the inner wall of the transverse connecting tube 130.

[0063] Embodiment 2 is a rice field spraying method proposed on the basis of Embodiment 1, and the spraying method includes the following two spraying modes:

[0064] ①Irrigation mode (normal mode):

[0065] The controller module locks and fixes the first connection part 110 and the second connection part 120 through the locking component, and the first connection part 110 and the second connection part 120 no longer rotate, closes the first electrically controlled valve 133 of the transverse connecting pipe 130, and opens the second electrically controlled valve 135 of the water inlet branch pipe 134, and water enters the transverse connecting pipe 130 through the vertical pipe 100 and the water inlet branch pipe 134, but does not enter the transverse connecting pipe 130 through the vertical pipe 100, the water collecting cylinder 101, the first connection part 110 and the second connection part 120. At this time, the water sprayed by the first nozzle 140 drives the transverse connecting pipe 130 to rotate unidirectionally relative to the vertical pipe 100, and the water sprayed by the first nozzle 140 irrigates the rice field crops near the vertical pipe 100 in all directions. At the same time, the second nozzle 150 is swung by the swing component, and the water sprayed by the second nozzle 150 irrigates the rice field crops far from the vertical pipe 100 in a large range, thereby increasing the irrigation range and keeping the rice field crops in a suitable moisture and temperature environment by water spraying irrigation;

[0066] ②Cooling and humidifying mode (extreme weather mode):

[0067] When the temperature sensor 160 detects that the outside atmospheric temperature is greater than the high temperature threshold, and the humidity sensor 161 detects that the air humidity is higher than the humidity threshold in an extreme dry and hot environment, the controller module loosens and fixes the first connection part 110 and the second connection part 120 through the locking assembly, and the first connection part 110 and the second connection part 120 can rotate, the first electric control valve 133 of the transverse connecting pipe 130 is opened, and the second electric control valve 135 of the water inlet branch pipe 134 is closed, and water enters the transverse connecting pipe 130 through the riser 100, the water collecting cylinder 101, the first connection part 110 and the second connection part 120, and does not pass through the riser 100 and the water inlet branch pipe 134. When the water enters the transverse connecting pipe 130, after passing through the rotating assembly and the swinging assembly, the transverse connecting pipe 130 can rotate by itself while revolving around the vertical pipe 100. The water sprayed by the first nozzle 140 can rotate back and forth relative to the vertical pipe 100 due to the periodic change in direction, so that the water sprayed by the first nozzle 140 and the second nozzle 150 can not only irrigate the rice field crops around the vertical pipe 100 in a large range, but also spray water into the upper air to cool it down and increase the air humidity under the rotation of the second connecting part 120, so as to keep the rice field crops in a suitable moisture and temperature environment.

[0068] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.

The power storage module is electrically connected to the temperature sensor and the humidity sensor, and the temperature sensor and the humidity sensor are both signal-connected to the controller module.

8. A rice field spraying method, comprising a rice field spraying device as claimed in any one of claims 1 to 7, characterized in that: The spray method includes the following spray patterns: ①Irrigation mode (normal mode): The controller module locks and fixes the first connection part and the second connection part through the locking component, and the first connection part and the second connection part no longer rotate, closes the first electrically controlled valve of the transverse connecting pipe and opens the second electrically controlled valve of the water inlet branch pipe, and water enters the transverse connecting pipe through the vertical pipe and the water inlet branch pipe, but does not enter the transverse connecting pipe through the vertical pipe, the water collecting cylinder, the first connection part and the second connection part. At this time, the water sprayed by the first nozzle drives the transverse connecting pipe to rotate unidirectionally relative to the vertical pipe, and the water sprayed by the first nozzle irrigates the rice field crops near the vertical pipe in all directions. At the same time, the second nozzle is swung by the swing component, and the water sprayed by the second nozzle irrigates the rice field crops far from the vertical pipe in a large range, thereby increasing the irrigation range and keeping the rice field crops in a suitable moisture and temperature environment by means of water spray irrigation; ②Cooling and humidifying mode (extreme weather mode): When the temperature sensor detects that the outside atmospheric temperature is greater than the high temperature threshold, and the humidity sensor detects that the air humidity is higher than the humidity threshold in an extreme dry and hot environment, the controller module loosens and fixes the first connection part and the second connection part through the locking assembly, and the first connection part and the second connection part can rotate, opening the first electrically controlled valve of the transverse connecting pipe and closing the second electrically controlled valve of the water inlet branch pipe, and water enters the transverse connecting pipe through the vertical pipe, the water collecting cylinder, the first connection part and the second connection part, but does not enter the transverse connecting pipe through the vertical pipe and the water inlet branch pipe. At this time, after the water passes through the rotating assembly and the swinging assembly, the horizontally pulled connecting pipe revolves around the vertical pipe and can also rotate by itself. The water sprayed by the first nozzle due to the periodic change in direction causes the transverse connecting pipe to reciprocate relative to the vertical pipe, so that the water sprayed by the first nozzle and the second nozzle can not only irrigate the paddy crops around the vertical pipe in a large range, but also spray water into the upper air to cool down and increase the air humidity under the rotation of the second connection part, so as to keep the paddy crops in a suitable moisture and temperature environment.
