Description

Technical Field

[0001] The utility model relates to the technical field of meteorological monitoring, in particular to a weighing rain gauge with improved stability. Background Art

[0002] A rain gauge is an instrument used by meteorologists and hydrologists to measure the amount of precipitation in a certain area over a period of time. The most common types are siphon type and tipping bucket type. The working principle of a weighing rain gauge is to use a receiver to collect rainwater, use a weighing tool to calculate the weight of rainwater received by the receiver over a period of time, and then calculate the precipitation based on the change in the weight of rainwater.

[0003] However, the weighing rain gauge currently used has a poor fixing effect when placed in a water bucket. When the water bucket contains rainwater, the water in the water bucket is often affected by wind or traffic vibration, causing the water bucket to overturn, resulting in incorrect measurement of the rain gauge or even a short circuit of the rain gauge sensor. Utility Model Content

[0004] The utility model discloses a weighing rain gauge with improved stability, aiming to solve the technical problem that the weighing rain gauge currently used has poor fixing effect when placed in a water bucket, and when rainwater is received in the water bucket, the rainwater in the water bucket often surges and overturns the water bucket due to the vibration of wind or traffic, resulting in measurement errors of the rain gauge and even short circuit of a rain gauge sensor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A weighing rain gauge with improved stability comprises a shell, a tray is provided in the shell, a groove is formed on the tray, and a spring 2 is fixedly connected to the bottom of the groove, one end of the spring 2 is fixedly connected to a pressure plate, and two symmetrical sliding grooves are provided on one side of the pressure plate, two symmetrical springs 3 are connected to the sides of the two sliding grooves close to the pressure plate by bolts, and the ends of the two springs 3 on the same side away from the pressure plate are fixedly connected to the same clamping block, the upper side of the tray is fixedly connected to two symmetrical supports, the opposite sides of the two supports are fixedly connected to the same short shaft, the outside of the short shaft is surrounded by a torsion spring, one end of the torsion spring is fixedly connected to the support, and the other end is fixedly connected to a movable rod, one side of the movable rod is fixedly connected to a fixing piece, the side of the movable rod close to the pressure plate is fixedly connected to a clamp, and the outside of the clamp is fixedly connected to extrusion blocks distributed equidistantly around the circumference.

[0007] By arranging a shell, a tray, a second paralysis part, a pressure plate, a third spring, a clamp, a support, a torsion spring, a movable rod, a clamp and an extrusion block, when the water barrel is placed on the pressure plate, the weight of the antifreeze and anti-evaporation oil in the water barrel will prompt the clamp to move downward along the inclined surface of the fixing part, so that the clamp on the movable rod fits with the barrel wall and fixes the water barrel; when rainwater is collected and measured, as the weight increases with the increase of water volume, the sinking of the pressure plate will prompt the clamp to continue to move downward; the greater the overall dead weight of the water barrel, the greater the restraint of the clamp on the water barrel, thereby preventing the water barrel from being overturned by the shaking rainwater in the barrel under the influence of factors such as wind and traffic conditions, thereby ensuring the measuring ability of the rain gauge and improving the stability of the rain gauge.

[0008] In a preferred embodiment, a concrete foundation is provided below the shell, and a connecting piece equidistantly distributed around the circumference is fixedly connected to the upper side of the concrete foundation, a guide rail is provided on one side of the connecting piece, and a column foot is slidably connected in the guide rail; a rack 1 is fixedly connected to one side of the connecting piece, a rectangular groove is provided on one side of the column foot, a positioning frame is fixedly connected in the rectangular groove, a symmetrical spring 1 is fixedly connected to the inner wall of the positioning frame, one end of two springs 1 is fixedly connected to the same rack 2, and rack 2 is meshed with rack 1; a circular hole is provided on one side of the positioning frame, a pull rod is slidably connected in the circular hole, and one side of the pull rod is fixedly connected to one side of rack 2.

[0009] By providing a concrete foundation, a connecting piece, a guide rail, a column foot, a rack 1, a positioning frame, a spring 1, a rack 2 and a pull rod, the position of the column foot and the connecting piece can be fixed by the guide rail on the connecting piece, thereby ensuring the stability of the connection; through the cooperation of the rack 1 and the rack 2, when installing the column foot, it is only necessary to engage the rack 2 on the column foot with the rack 1 on the connecting piece, so that the column foot can be quickly installed, thereby saving the time of the staff and improving the work efficiency.

[0010] In a preferred solution, the upper sides of the column bases are fixedly connected with vertical rods that are evenly spaced around the circumference, a T-shaped support is slidably connected inside the vertical rods, and a fine hole is opened on one side of the vertical rods, a threaded rod is arranged inside the fine hole; the upper sides of the T-shaped supports are fixedly connected with the same fixing ring, and a plurality of blades that are evenly spaced around the circumference are fixedly connected inside the fixing ring.

[0011] By arranging the vertical rod, the T-shaped support, the fixing ring and the blades, and by the cooperation between the fixing ring and the blades, the rain gauge can effectively capture snowfall, so that the rain gauge expands the measurement types and improves the convenience.

[0012] In a preferred embodiment, a base is fixedly connected to the upper side of the concrete foundation, a power box is fixedly connected to the outside of the base, and a flat plate is fixedly connected to the upper side of the base, circular holes are opened on the flat plate, fixed leveling bolts are arranged in the circular holes, the upper sides of the fixed leveling bolts are fixedly connected to the same base, the upper side of the base is connected to the bottom of the outer shell by a buckle, a sensor is fixedly connected to the upper side of the base, the upper side of the sensor is fixedly connected to the bottom of the tray, the upper side of the outer shell is fixedly connected to the water receiving port, and a water bucket is arranged on the upper side of the pressure plate.

[0013] A base, a power box, a flat plate, a fixed leveling bolt, a pedestal, a sensor, a water receiving port and a water bucket are provided. By adjusting the fixed leveling bolt, the base can be kept level, thereby ensuring the accuracy and reliability of the sensor in the shell and improving the working efficiency of the rain gauge. The edge of the water receiving port is in the shape of a built-in outer circular blade, which can effectively prevent raindrops from splashing and the bucket mouth from deforming, thereby ensuring the stability and safety of the device.

[0014] As can be seen from the above, the utility model provides a weighing rain gauge with improved stability. When a water barrel is placed on a pressure plate, the weight of the antifreeze and anti-evaporation oil in the water barrel will prompt the clamping block to move downward along the inclined surface of the fixing part, so that the clamp on the movable rod fits with the barrel wall to fix the water barrel. When rainwater is collected and measured, as the weight increases with the increase in water volume, the sinking of the pressure plate will prompt the clamping block to continue to move downward. The greater the overall dead weight of the water barrel, the greater the restraint of the clamp on the water barrel. This avoids the water barrel being overturned by the shaking rainwater in the barrel under the influence of factors such as wind and traffic conditions, thereby ensuring the measuring ability of the rain gauge and improving the technical effect of the stability of the rain gauge.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The utility model discloses a weighing rain gauge with improved stability, which is mainly applied to the situation that the currently used weighing rain gauge has poor fixing effect when placed in a water bucket.

When rainwater collection and measurement is performed, as the weight increases with the increase in water volume, the sinking of the pressure plate 25 will prompt the block 27 to continue to move downward. The greater the overall dead weight of the water barrel 16, the greater the restraint of the clamp 31 on the water barrel 16, thereby preventing the water barrel 16 from being overturned by the shaking rainwater in the barrel under the influence of factors such as wind and traffic conditions, thereby ensuring the measurement ability of the rain gauge and improving the stability of the rain gauge.

[0023] In a preferred embodiment, a concrete foundation 2 is provided below the shell 1, and the upper side of the concrete foundation 2 is connected with connecting members 17 distributed equidistantly around the circumference by bolts, a guide rail 18 is provided on one side of the connecting member 17, and a column foot 5 is slidably connected in the guide rail 18; a rack 19 is connected to one side of the connecting member 17 by bolts, a rectangular groove is provided on one side of the column foot 5, a positioning frame 20 is connected in the rectangular groove by bolts, and a symmetrical spring 1 21 is connected to the inner wall of the positioning frame 20 by bolts, one end of the two springs 1 21 is fixedly connected to the same rack 23, and the rack 23 is meshed with the rack 19; a circular hole is provided on one side of the positioning frame 20, a pull rod 22 is slidably connected in the circular hole, and one side of the pull rod 22 is connected to one side of the rack 23 by bolts; by pulling the pull rod 22, the rack 23 offsets the elasticity of the spring 1 21, so that the column foot 5 can be released from the lock with the connecting member 17, and the column foot 5 can be quickly disassembled and assembled, thereby improving convenience.

[0024] In a preferred embodiment, the upper side of the column base 5 is connected to vertical rods 6 that are evenly distributed around the circumference by bolts, a T-shaped support 7 is slidably connected inside the vertical rod 6, and a fine hole is opened on one side of the vertical rod 6, and a threaded rod is arranged in the fine hole; the upper side of the T-shaped support 7 is connected to the same fixing ring 8 by bolts, and the inside of the fixing ring 8 is connected to a plurality of blades 9 that are evenly distributed around the circumference by bolts; the T-shaped support 7 effectively provides a stable connection for the fixing ring 8 to prevent the fixing ring 8 from falling off, and the T-shaped support 7 can also be vertically adjusted on the vertical rod 6 to ensure that the windproof effect of the device is optimal.

[0025] In a preferred embodiment, the upper side of the concrete foundation 2 is connected to the base 3 by bolts, the outside of the base 3 is fixedly connected to the power box 4, and the upper side of the base 3 is connected to the plane plate 11 by bolts, the plane plate 11 is provided with equidistantly distributed circular holes, and the circular holes are provided with fixed leveling bolts 12, and the upper sides of the fixed leveling bolts 12 are fixedly connected to the same base 13, the upper side of the base 13 is connected to the bottom of the shell 1 by a buckle, the upper side of the base 13 is connected to the sensor 14 by bolts, the upper side of the sensor 14 is connected to the bottom of the tray 15 by bolts, the upper side of the shell 1 is connected to the water receiving port 10 by bolts, and the upper side of the pressure plate 25 is provided with a water bucket 16; through the cooperation of the tray 15 and the sensor 14, the tray 15 does not need to contact the shell 1, thereby avoiding the shell 1 being disturbed by wind or other factors to affect the measurement, thereby improving the measurement accuracy and efficiency of the rain gauge.

[0026] Working principle: When in use, the base 3 and the power box 4 are installed on the concrete foundation 2, the flat plate 11 and the base 13 are connected by fixing the leveling bolts 12, and then the sensor 14 is fixed on the base 13, and the tray 15 is installed on the sensor 14, and the water bucket 16 is placed on the pressing plate 25, and a proper amount of antifreeze and anti-evaporation oil are poured into the water bucket 16. Under the influence of gravity, the pressing plate 25 descends, prompting the block 27 to move downward along the inclined surface of the fixing member 32, so that the clamp 31 on the movable rod 30 fits with the bucket wall, and the water bucket 16 is placed on the pressing plate 25. The bucket 16 is fixed. When rainwater is collected and measured, as the amount of water increases and the weight increases, the sinking of the pressure plate 25 will prompt the block 27 to continue to move downward. The greater the overall weight of the water bucket 16, the greater the restraint of the clamp 31 on the water bucket 16. Then the shell 1 is connected to the base 13, and finally the column foot 5 connected to the vertical rod 6 is inserted into the connecting piece 17 on the concrete foundation 2.
