Description

Technical Field

[0001] The utility model belongs to the technical field of meteorological monitoring, and particularly relates to a fixing device for farmland meteorological observation instruments. Background Technique

[0002] Meteorological observation is a discipline that studies the methods and means of measuring and observing the physical and chemical properties of the earth's atmosphere and atmospheric phenomena. It mainly includes the concentration of atmospheric gases, aerosols, temperature, humidity, pressure, wind, atmospheric turbulence, evaporation, clouds, precipitation, radiation, atmospheric visibility, atmospheric electric field, atmospheric conductivity, as well as lightning, rainbow, halo, etc. From the perspective of disciplines, meteorological observation belongs to a branch of atmospheric science. It includes surface meteorological observation, upper-air meteorological observation, atmospheric remote sensing detection, and meteorological satellite detection, sometimes collectively referred to as atmospheric sounding. The meteorological observation system composed of various means can observe the atmospheric state and its changes from the ground to the upper layer and from the local area to the global area.

[0003] At present, more Internet technologies such as intelligent interconnection, Internet of Things, and big data are applied in agricultural production, which can effectively get rid of the influence of natural disasters, no longer be restricted by soil planting, and make agricultural operations more ecological, intelligent, urbanized, and liberalized. Nevertheless, the facility crops with little artificial intervention in microclimate only account for a very small part, and the vast majority of crops are still affected by the natural environment. Therefore, it is particularly important to make weather forecasts in advance and do a good job in agricultural meteorological disaster prevention and reduction in advance. At present, the number of meteorological stations officially built by the meteorological bureau is limited, and the covered areas are basically at the district and county scales. Due to factors such as terrain, climate, and altitude in some areas, the representativeness of the official weather forecast is limited, and there are large differences between the actual temperature, light, precipitation, etc. and the data measured by the meteorological station. There are deficiencies in the coverage breadth, refinement degree, etc. of agricultural meteorological observation, which has a certain impact on the prediction and prevention of local agricultural meteorological disasters.

[0004] Due to the influence of different agricultural tillage measures, different crops, and the dynamic changes of crop groups in agricultural production sites such as farmland, greenhouses, and pastures, the conditions of the farmland activity surface and various physical properties are constantly changing, resulting in changes in the components of local radiation balance and heat balance, thus forming various types of farmland microclimate characteristics. After a certain farmland microclimate is formed, as the environmental conditions for crop growth, it will directly affect the growth and development process and yield of crops. Therefore, it is necessary to install some meteorological instruments in some specific farmland environments to monitor meteorological data.

[0005] For example, a farmland meteorological station suitable for low temperature environments with a patent number application number of 2022219529125 discloses "including: a main body bracket, a first storage rod, a second storage rod, and a third storage rod; the first storage rod is horizontally welded to the top of the main body bracket through the upper surface of the main body bracket; the second storage rod and the third storage rod are both welded to the outer side wall of the main body bracket and extend in a direction away from the outer side wall; one end of the first storage rod is equipped with a solar panel, the other end is equipped with a solar radiation sensor above, and a rotatable camera is installed below through a suspension rod; a heat preservation ring surrounds the periphery of the connection between the suspension rod and the rotatable camera; the wind vane and the anemometer are both connected to the second storage rod through a heating base; a rain gauge is arranged on the third storage rod; the lower end of the main body bracket is fixedly supported on the ground through a plurality of support rods; the bottoms of the main body bracket and the support rods are both provided with bases. This farmland meteorological station can more accurately conduct refined observations of farmland meteorological information in low temperature environments." Although the above technical solution can realize the monitoring of meteorological data of farmland, it is not suitable for the transportation and installation of long meteorological equipment support columns in some mountainous areas or other special areas. Therefore, it is still a major problem to install meteorological instruments in the above-mentioned areas, and it is extremely time-consuming and laborious to transport and install the support rods of meteorological instruments.

[0006] In order to solve the above problems, we provide a fixing device for farmland meteorological observation instruments that can achieve segmented transportation of farmland in some remote areas and facilitate the installation of support rods. Utility Model Content

[0007] The purpose of the present utility model is to overcome the deficiencies existing in the prior art and provide a fixing device for farmland meteorological observation instruments.

[0008] The purpose of the present utility model is achieved in the following way: A fixing device for farmland meteorological observation instruments includes a base, a first vertical rod is arranged on the base, a second vertical rod is arranged above the first vertical rod, a connecting rod is arranged between the first vertical rod and the second vertical rod, the upper end of the connecting rod is detachably connected to the second vertical rod, and the lower end of the connecting rod is detachably connected to the first vertical rod.

[0009] Further, a first threaded rod is fixedly arranged at the lower end of the connecting rod, and a second threaded rod is fixedly arranged at the upper end of the connecting rod.

[0010] Further, the connecting rod is connected to the first vertical rod through the first threaded rod, a first threaded hole is opened at the upper end of the first vertical rod, and the first threaded rod and the first threaded hole on the first vertical rod are in threaded connection.

[0011] Further, the connecting rod is connected to the second vertical rod through the second threaded rod, a second threaded hole is opened at the lower end of the second vertical rod, and the second threaded rod and the second threaded hole on the second vertical rod are in threaded connection.

[0012] When the utility model is used, the vertical rod 1 is fixed on the base, and the vertical rod 2 is connected to the vertical rod 1 through the connecting rod; when connecting, the threaded rod 1 at the lower end of the connecting rod is first placed in the vertical rod 1, at this time the guide head 1 is located in the limiting groove below, and at the same time the limiting block 1 is pushed upward onto the guide head 1, and then the limiting block 1 is moved upward along the guide head 1 into the limiting groove, and the limiting groove and the limiting block fit with each other, which can prevent the limiting block and the limiting groove from rotating, and then the nut 1 is rotated to make it move upward along the vertical rod 1 until the upper end of the nut 1 squeezes and limits the limiting block, preventing the limiting block 1 from moving downward and out of the limiting groove; through the above operation, the limit between the connecting rod and the vertical rod 1 can be achieved, and rotation between the two can be prevented.

[0013] Then connect the second vertical pole to the connecting rod, that is, rotate the second vertical pole to connect it with the threaded rod 1 at the upper end of the connecting rod until the second guide head at the lower end of the second vertical pole is located in the limit groove, and the limit groove and the limit block 2 fit together to prevent the limit block 2 from rotating between the limit groove and the second vertical pole. Then rotate the second nut to move it downward along the second vertical pole until the lower end of the second nut fits with the limit block 2 to prevent the limit block 2 from moving upward and out of the limit groove. Through the above operation, the limiting connection between the connecting rod and the second vertical pole is achieved, and rotation between the two is prevented. Then install the corresponding meteorological measuring instrument on the second vertical pole and it can be used. There is no technical restriction on how to install the meteorological measuring instrument on the second vertical pole.

[0014] The above technical solution adopts a two-end structure to achieve the fixation of meteorological observation instruments. Since some remote areas or some fields are not suitable for transportation with longer supporting and fixing poles, the multi-section structure of the present application is adopted to support and fix the meteorological observation instruments, which can facilitate the transportation of the support poles and is simple and convenient to install. It can also be installed with more than two sections of vertical poles as needed. There is no specific technical restriction. The connection method between the vertical poles can adopt the connection method recorded in this application and is not limited to the above connection method.

[0015] At the same time, the present application can achieve limited fixation between the poles after connecting adjacent poles, so as to prevent them from rotating relative to each other and affecting the measurement values of the instruments fixed at the upper end; for example, in some areas with strong winds and long-term wind blowing, if the adjacent poles are only connected by threaded connections, rotation between the two will be caused, and then the instruments at the upper end will be rotated, affecting the data measurement.

[0016] Beneficial effects: The present application is a meteorological instrument fixing pole structure assembled in two or more sections, which can be easily transported, and the connection method between adjacent poles is simple and easy to operate. At the same time, rotation between the poles can be avoided after the poles are connected. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1, as Figure 1 —4 shows, the purpose of the present utility model is realized as follows: A fixing device for a farmland meteorological observation instrument, including a base, a first vertical rod 1 is arranged on the base, a second vertical rod 3 is arranged above the first vertical rod 1, a connecting rod 2 is arranged between the first vertical rod 1 and the second vertical rod 3, the upper end of the connecting rod 2 is detachably connected to the second vertical rod 3, and the lower end of the connecting rod 2 is detachably connected to the first vertical rod 1. By combining multiple vertical rods, it is convenient to transport to some places where it is not convenient to transport long vertical rods.

[0024] The lower end of the connecting rod 2 is fixedly provided with a first threaded rod 8, and the upper end of the connecting rod 2 is fixedly provided with a second threaded rod 4. The connecting rod 2 is connected to the first vertical rod 1 through the first threaded rod 8. A first threaded hole is opened at the upper end of the first vertical rod 1, and the first threaded rod 8 and the first threaded hole on the first vertical rod 1 are in threaded connection. The connecting rod 2 is connected to the second vertical rod 3 through the second threaded rod 4. A second threaded hole is opened at the lower end of the second vertical rod 3, and the second threaded rod 4 and the second threaded hole on the second vertical rod 3 are in threaded connection.

[0025] The first vertical rod 1 and the second vertical rod 3 are arranged in a cylindrical structure, and the connecting rod 2 is arranged in a non-circular structure, which is convenient for the installation and combination of the first vertical rod 1, the second vertical rod 3 and the connecting rod 2. That is, the non-cylindrical structure of the connecting rod 2 is beneficial for the tool to drive it to rotate, and the cylindrical structures of the first vertical rod 1 and the second vertical rod 3 can reduce wind resistance.

[0026] Limiting grooves are respectively provided at the upper and lower ends of the connecting rod 2. The limiting grooves are non-cylindrical structures, which are conducive to the limitation between the limiting block and the limiting groove to prevent rotation between the two. The upper end of the vertical pole 1 and the lower end of the vertical pole 2 3 are respectively provided with a limiting block 10 and a limiting block 2 6 which can be moved up and down. The limiting block 10 and the limiting block 2 6 can be moved up and down in the limiting groove. There is a clearance fit between the limiting block 10, the limiting block 2 6 and the limiting groove, and the limiting block 10, the limiting block 2 6 and the limiting groove fit each other.

[0027] A guide head 9 is provided at the upper end of the vertical rod 1, a limit block 10 is located on the guide head 9 and can be moved up and down, and a nut 11 is threadedly connected to the vertical rod 1 below the guide head 9. The guide head 9 is rotatably located in the limit slot.

[0028] A guide head 25 is provided at the lower end of the vertical rod 3. A stopper 26 is positioned on the guide head 25 and can be moved up and down. A nut 27 is threadedly connected to the vertical rod 3 above the guide head 25. The lower end surface of the nut 27 is convex around the periphery. When the nut 27 is in contact with the stopper 26, the lower end of the nut 27 is positioned above the connecting rod 2. The outward convex portion of the lower end surface of the nut 27 covers the upper end surface of the connecting rod 2, thereby reducing the ingress of rainwater and other external factors into the connection between the connecting rod 2 and the vertical rod 3. The guide head 25 is rotatably positioned within the stopper slot. When the guide head 1 9 and the guide head 2 5 are located in the limit groove, the guide head and the connecting rod 2 can rotate relative to each other, that is, the guide head 1 9 and the guide head 2 5 cannot affect the rotation of the connecting rod 2 relative to the vertical rod when they are in the limit groove; when the connecting rod 2 and the vertical rod are rotated to the tightening position, the limit block can be moved up and down, and when the limit block moves up and down along the guide head to the limit groove, the inner side of the limit block is in contact with the guide head and cannot rotate, and the outer side of the limit block is in contact with the inner side of the limit groove and cannot rotate; thereby achieving the limitation between the vertical rod and the connecting rod 2.

[0029] When the present invention is in use, the vertical pole 1 is fixed on the base, and the vertical pole 2 3 is connected to the vertical pole 1 through the connecting rod 2; when connecting, the threaded rod 8 at the lower end of the connecting rod 2 is first placed in the vertical pole 1, at this time the guide head 9 is located in the limiting groove below, and the limiting block 10 is pushed upward onto the guide head 9, and then the limiting block 10 is moved upward along the guide head 9 into the limiting groove, and the limiting groove and the limiting block fit with each other, which can prevent the limiting block and the limiting groove from rotating, and then the nut 11 is rotated to make it move upward along the vertical pole 1 until the upper end of the nut 11 squeezes and limits the limiting block, preventing the limiting block 10 from moving downward and out of the limiting groove; through the above operation, the limit between the connecting rod 2 and the vertical pole 1 can be achieved, and rotation between the two can be prevented.

[0030] Then, connect the second vertical rod 3 to the connecting rod 2, that is, rotate the second vertical rod 3 to connect it to the first threaded rod 8 at the upper end of the connecting rod 2 until the guiding head 5 at the lower end of the second vertical rod 3 is located in the limiting groove. The limiting groove and the second limiting block 6 fit with each other, which can prevent rotation between the second limiting block 6 and the limiting groove. Then, rotate the second nut 7 to move it downward along the second vertical rod 3 until the lower end of the second nut 7 fits with the second limiting block 6, preventing the second limiting block 6 from moving upward out of the limiting groove. Through the above operations, the limiting connection between the connecting rod 2 and the second vertical rod 3 can be achieved, and rotation between the two can be avoided. Then, install the corresponding meteorological measuring instrument on the second vertical rod 3 to use it. There is no technical limitation on how to install the meteorological measuring instrument on the second vertical rod 3.

[0031] The above technical solution adopts a two-end structure to fix the meteorological observation instrument. Since some remote areas or some fields are not suitable for transporting long support fixing rods, adopting the multi-section structure of this application to support and fixedly install the meteorological observation instrument can facilitate the transportation of the support rod. At the same time, the installation is simple and convenient, and more than two vertical rods can be set for installation according to needs. There is no specific technical limitation. The connection method between the vertical rods can adopt the connection method described in this application and is not limited to the above connection method.

[0032] At the same time, after connecting adjacent vertical rods in this application, the limiting fixation between the vertical rods can be achieved, avoiding rotation between them and affecting the measurement value of the instrument fixed at the upper end. For example, in some areas with strong winds, if the adjacent vertical rods are only connected by a threaded connection for a long time under the blowing of the wind, rotation between the two may occur, and then the instrument at the upper end may rotate, affecting the determination of data.

[0033] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes.
