Description

Technical Field

[0001] The present invention relates to the field of meteorological disaster early warning, and in particular to an agricultural meteorological disaster early warning device and a use method thereof. Background Art

[0002] Agriculture is extremely sensitive to weather conditions, and meteorological disasters such as drought, floods, hail, and frost can cause serious damage to crops. In agricultural production activities, relevant meteorological disaster warning devices are often needed to monitor the temperature, humidity, and wind speed in the outdoor environment, so that farmers can get early warnings and take corresponding rescue measures. Therefore, timely and accurate meteorological disaster warnings are crucial to reducing losses.

[0003] With the advancement of science and technology, technicians in related fields have also optimized the technical means of meteorological disaster warning. In order to make a more accurate comparison, a Chinese patent with publication number CN220933587U discloses an agricultural meteorological disaster warning device, including a protective box, a motor, a screw rod, a movable plate, and a rack, etc. When it is in use, through the mutual coordination between the motor, the screw rod, the movable plate, the rack, and the half gear, when it is necessary to repair the photovoltaic power generation panel and the meteorological monitor, the mounting bracket can be tilted to reduce the height of the photovoltaic power generation panel and the meteorological monitor, so that the operator does not need to lift to a certain height to carry out the maintenance work, making the operation of repairing components such as photovoltaic power generation panels and meteorological monitors relatively simple, reducing the labor intensity of the operator.

[0004] However, when using the above-mentioned existing technologies to warn of meteorological disasters, there are still the following problems:

[0005] 1. Since the height of the meteorological monitor needs to be adjusted according to the characteristics of the corresponding area during actual use, the above-mentioned device is fixedly connected to the mounting bracket through a rotating plate, and the monitor is connected to the mounting bracket for meteorological monitoring. The sizes of the rotating plate and the mounting bracket are set to be fixed and cannot be adjusted. In actual use, the height of the installed monitor is fixed and cannot monitor the weather at different heights. The monitored data is not comprehensive.

[0006] 2. The above-mentioned device uses a protective box and an arc plate to limit the installation of the rotating plate and the mounting bracket, and the rotating plate is connected to the lower end of the mounting bracket. In actual use, the monitor usually needs to be installed at a certain height for weather monitoring, and the above-mentioned device only limits the rotating plate at the lower end of the mounting bracket when used. When used in severe weather conditions, the mounting bracket with the monitor installed is easily attacked by strong winds and blown to cause shaking, thereby causing the overall overturning of the device, affecting the normal use of the monitor.

[0007] Therefore, based on the above-stated view, there is still room for improvement in the existing technical means of providing early warning for meteorological disasters. Summary of the invention

[0008] In order to solve the above problems, the present invention provides an agricultural meteorological disaster warning device, including a mounting base and a mounting rod passing through the mounting base for connecting a monitor, and the mounting base is also connected to an adjuster for adjusting the position of the monitor in the vertical direction.

[0009] The regulator includes a plurality of adjusting links which are evenly distributed circumferentially around the mounting rod on the outside of the mounting base, the adjusting links being connected to the mounting base via a rotating seat, and driven guide plates with a telescopic structure are connected to the opposite sides of all the adjusting links, and all the driven guide plates are commonly connected to a driving screw which is inserted into the mounting base on the side away from the connected adjusting links, and the relative position between the adjusting links and the mounting base can be adjusted by the mutual cooperation between the driving screw and all the driven guide plates, thereby achieving the effect of adjusting the height of the monitor.

[0010] Preferably, the regulator also includes a limit sleeve coaxially sleeved on the outside of the mounting rod and simultaneously penetrated on the mounting base, a limit block is also connected to the side of the limit sleeve away from the mounting rod, and a compression spring located in the limit sleeve is commonly connected between the limit block and the mounting rod.

[0011] Preferably, the driving screw is inserted into the limiting sleeve and the thread passes through the limiting block.

[0012] Preferably, the outer side surface of the mounting rod is sleeved with a driven slider located in a limiting sleeve, the end of the compression spring away from the limiting block is connected to the driven slider, and both ends of the limiting sleeve are arranged in a closed shape to limit the sliding range of the limiting block and the driven slider.

[0013] Preferably, the outer side surfaces of the driven slider and the limiting block are both connected with an extension slider inserted on the inner side wall of the limiting sleeve, so as to limit the rotation of the driven slider and the limiting block.

[0014] Preferably, sliding grooves for sliding of driven guide plates are opened on opposite sides of several of the adjusting links, and extension sliding rods connected to the driven guide plates are inserted in the sliding grooves. The extension sliding rods are passed through the adjusting links and slide along the sliding grooves to extend the adjusting links.

[0015] Preferably, the end of the extending slide rod away from the connected adjusting link is configured in a conical thorn shape so as to be inserted into the ground to limit and fix the entire device.

[0016] Preferably, the outer side surface of the driving screw is also sleeved with a protective shell connected to the driven guide plate.

[0017] Preferably, a plurality of spikes are evenly connected to the lower end of the protective shell in a circumferential direction.

[0018] In addition, the present invention also provides an agricultural meteorological disaster early warning method, comprising the following steps:

[0019] S1: Install the corresponding monitoring instrument through the mounting base and the mounting rod, and then adjust the deflection angle between the connecting rod and the mounting base by controlling to adjust the installation height of the monitoring instrument.

[0020] S2: After the adjustment of the deflection angle between the adjusting link and the mounting base is completed, the end of the adjusting link away from the mounting base after deflection is limited and fixed on the ground to complete the fixed installation of the monitoring instrument.

[0021] S3: When the monitoring instrument needs to be maintained, it is only necessary to adjust the relative position between the adjusting rod and the mounting base, so that the height of the monitoring instrument installed at a higher place can be lowered, thereby facilitating maintenance by the staff.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The present invention connects a plurality of adjusting links evenly in the circumferential direction of the outer side of the mounting base, and then realizes the adjustment of the relative position between the adjusting links and the mounting base through the mutual cooperation between the driving screw and all the driven guide plates, thereby achieving the effect of adjusting the height of the monitor. At the same time, the driving screw drives the extension sliding rod to slide on the adjusting link, thereby achieving the effect of adaptively adjusting the installation height of the meteorological monitor, so that the data monitored by the monitor is more comprehensive and accurate.

[0024] 2. The present invention forms a support frame by means of the mutual cooperation between the mounting base, a plurality of adjusting connecting rods, a driven guide plate and a protective shell, which can effectively improve the stability of the monitor after installation and avoid the problem of the monitor being easily overturned by external interference after being installed at a high place.

[0025] 3. The present invention can quickly extend the mounting rod out of the limiting sleeve to install the monitor at a certain height through the mutual sliding cooperation between the driving screw and the mounting rod arranged in the limiting sleeve and through the compression spring arranged in the limiting sleeve and located between the opposite sides of the driving screw and the mounting rod. Then, when maintenance is needed, the compression spring is continuously compressed and the upward movement and reset of the mounting rod are limited by the threaded cooperation between the driving screw and the mounting rod, thereby lowering the monitor on the mounting rod to a lower height so that the staff can maintain the monitor without dismantling the entire device.

[0026] Fourth, after the present invention drives the driving screw and the protective shell to fit with the ground, the driving force applied by the compression spring makes the limit block, the driving screw, the driving end, the protective shell and the plurality of spikes tend to always move downward, thereby further increasing the stability of the device after installation.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 To Attachment Figure 8 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0038] The embodiment of the present application discloses an agricultural meteorological disaster early warning device and method, which explains that the agricultural meteorological disaster early warning device and method are mainly used in the process of early warning of agricultural meteorological disasters. In terms of technical effect, the meteorological environment in the outdoor environment can be monitored by the installed meteorological monitoring instrument, so that farmers can be warned in advance; in particular, during the installation and use of the early warning device, the extension slide rod is driven by the driving screw to slide on the adjusting connecting rod, so as to achieve the effect of adaptive adjustment of the installation height of the meteorological monitor, so that the data monitored by the monitor is more comprehensive and accurate; and the agricultural meteorological disaster early warning device also forms a stable support frame through the mutual cooperation between the installation base and a plurality of adjusting connecting rods distributed circumferentially on its outer side surface, thereby achieving the effect of improving the stability of the device when in use.

[0039] Reference Figure 1 As shown, an agricultural meteorological disaster early warning device includes a mounting base 1, a mounting rod 10 and an adjuster 2. The mounting base 1 is provided with a mounting rod 10 for connecting a monitor 11. The mounting rod 10 is also connected to a controller for controlling the monitor 11 and a solar photovoltaic panel for supplementing electric energy. The mounting base 1 is also connected to an adjuster 2 for adjusting the position of the monitor 11 in the vertical direction. When in use, the position of the mounting rod 10 connected to the mounting base 1 is adjusted by the adjuster 2, so that the height of the monitor 11 connected to the mounting rod 10 can be adjusted, so that subsequent staff can dismantle and maintain it.

[0040] It should be noted that the monitor 11 is a special meteorological monitor 11, which is mainly used to monitor the temperature, humidity and wind speed in the outdoor environment. This is an existing conventional technical means and will not be elaborated here.

[0041] Reference Figure 2 As shown, the regulator 2 is used to adjust the position of the monitor 11 in the vertical direction; specifically, the regulator 2 includes an adjusting link 20, a driven guide plate 21, a driving screw 22 and a driving end 23. A plurality of adjusting links 20 are evenly connected to the outer side of the mounting base 1 with the mounting rod 10 as the axis in the circumferential direction. The adjusting link 20 is connected to the mounting base 1 through a rotating seat. The end of the adjusting link 20 close to the mounting base 1 is rotatably connected to the rotating seat. The rotating seat is fixedly connected to the mounting base 1. A driven guide plate 21 with a telescopic structure is connected to the opposite side of all the adjusting links 20. The side of all the driven guide plates 21 away from the connected adjusting link 20 is commonly connected to a driving screw 22 penetrating the mounting base 1. The end of the driving screw 22 away from the mounting base 1 is connected to the driving end 23. The driving screw 22 and all the driven guide plates 21 cooperate with each other to achieve the adjustment of the relative position between the adjusting link 20 and the mounting base 1, thereby achieving the effect of adjusting the height of the monitor 11.

[0042] When in use, the driving end 23 drives the driving screw 22 to rotate in the forward direction. After the driving screw 22 rotates, it drives all the driven guide plates 21 to slide in the direction away from the mounting base 1. At the same time, the driven guide plates 21 are extended accordingly after being away from the mounting base plate, and drive the connected adjusting links 20 to deflect at an angle with the rotating axis between the rotating seat as the central axis, so that all the adjusting links 20 are deflected and opened in the direction away from each other. After all the adjusting links 20 have formed a certain deflection angle with the mounting base 1, the end of the adjusting link 20 away from the mounting base 1 is inserted into the ground to complete the installation and limit fixation of the monitor 11 on the mounting rod 10.

[0043] It should be noted that the number of the adjustment links 20 is preferably set to three, and a stable triangular support frame is formed between the three adjustment links 20 evenly distributed circumferentially on the mounting base 1 and the mounting base 1 to improve the stability of the monitor 11 when it is installed at a higher height.

[0044] Reference Figure 2 and Figure 3 As shown, the regulator 2 also includes a limiting sleeve 24, a limiting block 25 and a compression spring 26. The outer side of the mounting rod 10 is coaxially sleeved with a limiting sleeve 24 that is inserted into the mounting base 1. The side of the limiting sleeve 24 away from the mounting rod 10 is also connected to the limiting block 25. The limiting block 25 and the mounting rod 10 are commonly connected with a compression spring 26 located in the limiting sleeve 24. It should be noted that in the initial state, that is, when the mounting rod 10 is contracted in the limiting sleeve 24, the compression spring 26 is in a compressed and contracted state.

[0045] When in use, after the restriction on the mounting rod 10 is released, driven by the elastic return of the compression spring after being compressed, the two ends of the compression spring 26 respectively drive the mounting rod 10 and the limit block 25 to slide and separate along the inner wall of the limit sleeve 24 in the direction away from each other, so that the mounting rod 10 drives the connected monitor 11 to extend upward, and the monitor 11 is installed at a predetermined height position, and the limit block 25 is driven by the compression spring 26 to fit the inner wall of the limit sleeve 24.

[0046] Further, in order to facilitate the limited installation of the mounting rod 10, refer to Figures 2 to 4 As shown, the driving screw 22 is inserted into the limiting sleeve 24 and is threadedly connected with the limiting block 25, and the driving screw 22 is also threadedly inserted into the mounting rod 10. In the initial state, when the lower end of the mounting rod 10 is retracted into the limiting sleeve 24, the compression spring 26 is compressed in the limiting sleeve 24 and is located between the limiting block 25 and the mounting rod 10, and at the same time, the driving screw 22 simultaneously passes through the limiting block 25 and is inserted into the mounting rod 10 to limit the mounting rod 10.

[0047] When it is necessary to release the limit of the mounting rod 10 to install the monitor 11, the drive screw 22 is driven to rotate forward. After the drive screw 22 rotates, the mounting rod 10 slides in the direction away from the limit block 25 through the thread on the drive screw 22 until the mounting rod 10 and the drive screw 22 are out of the threaded insertion state. At this time, driven by the elastic reset force of the connected compression spring 26, the mounting rod 10 is pushed to slide upward along the inner side wall of the limit sleeve 24, and the limit block 25 is simultaneously pushed to slide downward along the inner side wall of the limit sleeve 24 and fit the bottom of the limit sleeve 24, thereby completing the effect of releasing the limit of the mounting rod 10.

[0048] Reference Figures 3 to 5 As shown, a driven slider 27 is rotatably sleeved on the outer side of the mounting rod 10 and slides in contact with the limiting sleeve 24. The end of the compression spring 26 away from the limiting block 25 is connected to the driven slider 27. Both ends of the limiting sleeve 24 are configured to be closed to limit the sliding range of the limiting block 25 and the driven slider 27, thereby avoiding the problem of the mounting rod 10 accidentally detaching from the limiting sleeve 24.

[0049] Reference Figures 3 to 5 As shown, the outer side surfaces of the driven slider 27 and the limiting block 25 are connected to an extension slider 270 slidably inserted on the inner wall of the limiting sleeve 24, which is used to limit the rotation of the driven slider 27 and the limiting block 25, and a guide groove adapted to the extension slider 270 is provided in the limiting sleeve 24 corresponding to the sliding path of the extension slider 270.

[0050] When in use, the extension slider 270 inserted on the inner side is limited by the guide groove, so as to achieve the limitation of the driven slider 27 and the limit block 25 connected to the extension slider 270. When the driving screw 22 is rotated, the driven slider 27 and the limit block 25 are restricted from being driven by the driving screw 22 to rotate, so as to achieve the effect of driving the limit block 25 and the mounting rod 10 to slide along the inner wall of the limit sleeve 24 through the rotation of the driving screw 22, thereby achieving the effect of driving the monitor 11 connected to the mounting rod 10 to adjust the height.

[0051] Reference Figures 6 to 8 As shown, sliding grooves for sliding the driven guide plate 21 are opened on the opposite sides of the several adjusting links 20, and an extension slide bar 28 connected to the driven guide plate 21 is inserted in the sliding groove. The extension slide bar 28 is passed through the adjusting link 20 and slides along the sliding groove to extend the adjusting link 20.

[0052] When in use, by driving the driving screw 22 to rotate forward, after the compression spring 26 presses the limit block 25 against the bottom of the limit sleeve 24, the compression spring 26 exerts an elastic pressing force on the limit block 25 that is always downward, and at this time, continuing to rotate the driving screw 22 forward will cause the driving screw 22 to gradually move downward and disengage from the limit block 25. After the driving screw 22 moves downward relative to the limit block 25, it drives the connected driving end 23 and all the driven guide plates 21 to move downward and extend. The driven guide plate 21 moves downward and drives the connected extension slide bar 28 to slide along the sliding groove in the direction away from the adjusting link 20, so as to extend the length of the adjusting link 20. By extending the connected adjusting link 20 with the extension slide bar 28, the monitor 11 of the mounting rod 10 can be installed at a predetermined higher height, and then all the extended extension slide bars 28 are limited or fixed to the ground to complete the installation of the monitor 11.

[0053] At this time, by controlling the downward movement distance of the driving screw 22 relative to the limit block 25, the installation height of the monitor 11 can be adjusted, so that the monitor 11 can be installed at different heights relative to the regional environment, thereby improving the monitoring effect of the monitor 11 and ensuring the accuracy and effectiveness of the data.

[0054] If the installed monitor 11 needs to be maintained at this time, as an optional implementation, when the monitor 11 needs to be dismantled as a whole for maintenance, it is necessary to first release the limit of all the extended slide bars 28 at the lower end, and then drive the drive screw 22 to rotate in the opposite direction. At this time, through the threaded cooperation between the drive screw 22 and the limit block 25, and the downward pressure applied by the compression spring 26 to the limit block 25, the drive screw 22 rotates in the opposite direction and slides upward relative to the limit block 25, and simultaneously drives the drive end 23 and the driven guide plate 21 to move upward. The upward movement of the driven guide plate 21 synchronously drives the connected extension slide bar 28 to slide along the sliding groove toward the mounting base 1, so as to achieve the effect of contracting the adjustment link 20.

[0055] After the driving screw 22 moves up and contacts the mounting rod 10, the driving screw 22 and the mounting rod 10 are restored to the plug-in state through the threaded cooperation between the driving screw 22 and the mounting rod 10, and the compression spring 26 is compressed and reset again, thereby completing the overall dismantling and extension of the monitor 11, so that the staff can carry out dismantling and maintenance.

[0056] If the entire monitor 11 does not need to be dismantled for maintenance, it is only necessary to lower the height of the monitor 11 at the upper end. At this time, it is only necessary to apply a downward pressure force to all the adjustment links 20 at the same time, so that the adjustment links 20 move downward relative to the connected extension slide bar 28. The downward movement of the adjustment links 20 drives the mounting base 1, the limiting sleeve 24 and the mounting rod 10 to move downward, while the extension slide bar 28 and the driving screw 22 have not yet moved, and the limiting block 25 connected to the end of the compression spring 26 away from the mounting rod 10 is held by the driving screw 22. The mounting rod 10 is limited in position, so at this time, due to the downward movement of the mounting rod 10, the connected compression spring 26 is compressed again until the lower end of the mounting rod 10 conflicts with the driving screw 22. At this time, the driving screw 22 is rotated to be threadedly connected with the mounting rod 10. The threads between the driving screw 22 and the mounting rod 10 are matched to limit the upward movement and reset of the mounting rod 10, so that the monitor 11 on the mounting rod 10 is lowered to a lower height so that the staff can maintain the monitor 11 when the entire device is dismantled.

[0057] Reference Figure 6 As shown, the end of the extended slide rod 28 away from the connected adjustment link 20 is configured in the shape of a conical spur 290 so as to be inserted into the ground to limit and fix the entire device.

[0058] Reference Figures 6 to 8 As shown, the outer side of the driving screw 22 is also sleeved with a protective shell 29 connected to the driven guide plate 21. When the driving screw 22 slides along the axial direction of the limiting sleeve 24, it synchronously drives the connected driving end 23 and the protective shell 29 to move, and the movement of the protective shell 29 drives the driven guide plate 21 to move, so as to drive the extension slide bar 28 to extend or retract. After the overall installation of the monitor 11 is completed, the driving end 23 is protected by the protective shell 29 to prevent the driving end 23 from being eroded by external water vapor or debris.

[0059] Reference Figure 6 As shown, the lower end of the protective shell 29 is evenly connected with a number of spikes 290 in the circumferential direction, and the stability of the device after installation is further increased by the cooperation between the triangular support frame constructed by the mounting base 1, the adjustment link 20 and the extension slide rod 28 on the outside, and the spikes 290 on the middle protective shell 29 inserted into the ground.

[0060] It should be noted that, in the specific implementation process, since the compression spring 26 in the limiting sleeve 24 is in a compressed state, after pushing the mounting rod 10 and the driven slider 27 to fit against the top of the limiting sleeve 24, and pushing the limiting block 25 to abut against the bottom of the limiting sleeve 24, it is still not fully extended and has a driving force on the mounting rod 10 and the limiting block 25 connected at both ends to always protrude from the limiting sleeve 24. Therefore, after driving the driving screw 22 and the protective shell 29 to fit against the ground, the driving force applied by the compression spring 26 causes the limiting block 25, the driving screw 22, the driving end 23, the protective shell 29 and the plurality of spikes 290 to always have a downward tendency, thereby further increasing the stability of the device after installation.

[0061] In addition, the present invention also provides an agricultural meteorological disaster early warning method, comprising the following steps:

[0062] S1: Install the corresponding monitor 11 through the mounting base 1 and the mounting rod 10, and then control and adjust the deflection angle between the connecting rod 20 and the mounting base 1 to adjust the installation height of the monitor 11.

[0063] S2: After the adjustment of the deflection angle between the adjusting link 20 and the mounting base 1 is completed, the end of the deflected adjusting link 20 away from the mounting base 1 is limited and fixed on the ground to complete the fixed installation of the monitoring instrument 11.

[0064] S3: When the monitor 11 needs to be maintained, it is only necessary to adjust the relative position between the adjusting link 20 and the mounting base 1, so that the monitor 11 installed at a higher place is lowered, thereby facilitating maintenance by the staff.

[0065] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0066] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
