Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a windproof rainfall sensor for meteorological monitoring. Background Art

[0002] Rainfall sensor (rain gauge) is the main equipment used for rainfall observation. It can measure the rainfall amount and rainfall intensity per unit time. Currently, the instruments and equipment used for automatic rainfall measurement are mainly tipping bucket type and weighing type rainfall sensors in terms of measurement methods.

[0003] However, in the prior art, traditional rain sensors are usually not equipped with windproof mechanisms. Therefore, during use, if there is windy weather, the accurate value of the rain sensor will be affected by the wind. In addition, traditional equipment is usually directly exposed to the outside world. Therefore, when it rains, the rain sensor will be exposed to the rain for a long time, which will cause rainwater to penetrate into the interior of the sensor, thereby damaging the sensor.

[0005] Sensor body;

[0006] A chassis, the top of which is fixedly connected to the bottom of the sensor body;

[0007] A windproof mechanism, the bottom of which is rotatably connected to the inner wall of the chassis, and the windproof mechanism is used to prevent wind from blowing onto the sensor;

[0008] An adjusting mechanism, the outer wall of which is fixedly connected to the outer wall of the windproof mechanism, and the adjusting mechanism is used to prevent rainwater from entering the windproof mechanism;

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a windproof mechanism and utilizes the wind to blow onto the windward circle, so that the windward circle turns to the wind direction.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art.

[0022] Example:

[0023] See also Figure 1 - Figure 4 The utility model provides a technical solution: a windproof rainfall sensor for meteorological monitoring, comprising:

[0024] Sensor body 1;

[0025] A chassis 2, the top of the chassis 2 is fixedly connected to the bottom of the sensor body 1;

[0026] A windproof mechanism 3, the bottom of which is rotatably connected to the inner wall of the chassis 2;

[0027] An adjusting mechanism 4, the outer wall of which is fixedly connected to the outer wall of the windproof mechanism 3;

[0028] The wind protection mechanism 3 includes a swivel 35, the top of the swivel 35 is fixedly connected to a wind shield ring 33, the top of the wind shield ring 33 is fixedly connected to a fixing plate 36, the top of the wind shield ring 33 is fixedly connected to a windward ring 31, and the outer wall of the wind shield ring 33 is fixedly connected to a rain shield ring 32. When rainwater falls on the rain shield ring 32, it will slide down along the outer wall of the rain shield ring 32, thereby preventing rainwater from falling into the wind protection mechanism 3.

[0029] The outer wall of the swivel 35 is rotatably connected to the inner wall of the chassis 2, and air holes 34 are opened in the wall of the wind shield ring 33, and the air holes 34 are linearly arrayed along the outer wall of the wind shield ring 33. The adjustment mechanism 4 includes a retaining ring 45, and the top of the retaining ring 45 is fixedly connected to a fixed block 43, the outer wall of the fixed block 43 is slidably connected to a limit block 41, and the inner wall of the limit block 41 is slidably connected to an insert block 42, which is inserted into the fixed block 43 and penetrates the limit block 41, so that the fixed block 43 is fixed on the limit block 41.

[0030] The outer wall of the retaining ring 45 is slidably connected to the outer wall of the wind shield ring 33, and the retaining ring 45 is used to block the air hole 34, thereby preventing rainwater from entering the wind protection mechanism 3 through the air hole 34. The bottom of the limit block 41 is fixedly connected to the top of the fixing plate 36, and the inner wall of the fixing block 43 is slidably connected to the outer wall of the plug block 42 through the slot 44, and the slot 44 is opened in the wall of the fixing block 43.

[0031] Working principle:

[0032] When in use, first place the chassis 2 at the meteorological monitoring point. After the position of the chassis 2 is stable, start the sensor body 1 to monitor the rainfall. While the sensor body 1 is monitoring the rainfall, the windproof mechanism 3 will protect the sensor body 1 to prevent the detection error of the sensor body 1 caused by wind factors. When the wind blows onto the windproof mechanism 3, the windward circle 31 in the windproof mechanism 3 will rotate to the wind direction, thereby forcing the wind shield circle 33 to be in the wind direction. Through the obstruction of the wind shield circle 33, the influence of the wind on the sensor body 1 can be reduced. In addition, when it is in windy and rainy weather, the position of the baffle ring 45 can be changed by the adjusting mechanism 4, so that the baffle ring 45 blocks the air hole 34 on the wind shield circle 33 to prevent rainwater from entering the interior of the windproof mechanism 3 through the air hole 34, thereby affecting the sensor body 1.

[0033] When the wind blows onto the windproof mechanism 3, resistance is generated when the wind blows onto the windward circle 31, thereby driving the windward circle 31 to rotate to the wind direction, and the wind continues to blow onto the windward circle 31, thereby maintaining the position of the windward circle 31. When the wind direction changes, the position of the windward circle 31 will also change, because the wind shielding circle 33 is fixed to the bottom of the windward circle 31. Therefore, when the windward circle 31 rotates, the position of the wind shielding circle 33 also changes with the windward circle 31. Moreover, because the shape of the wind shielding circle 33 is opposite to that of the windward circle 31, the wind blows onto the windproof mechanism 3. After reaching the outer wall of the wind shield 33, the wind will disperse to both sides of the wind shield 33 along the outer wall of the wind shield 33 to prevent the wind from blowing onto the sensor body 1. The rotating ring 35 at the bottom of the wind shield 33 is used to assist the rotation of the wind shield 33, and the air holes 34 on the wind shield 33 are used to allow breeze to pass through the wind shield 33, thereby keeping the surface of the sensor body 1 dry. A rain shield ring 32 is provided on the top of the wind shield 33. Through the blocking of the rain shield ring 32, the rainwater on the wind protection mechanism 3 can flow out along the rain shield ring 32 to prevent the rainwater from splashing onto the sensor body 1.

[0034] In windy and rainy weather, the staff can pull out the plug block 42 on the fixed block 43, so that the plug block 42 slides out of the slot 44, thereby releasing the lock on the limit block 41, and then the staff can slide the baffle ring 45 up and down to make the baffle ring 45 block the air hole 34 on the wind shield ring 33, thereby preventing rainwater from entering the wind protection mechanism 3 through the air hole 34. After the baffle ring 45 blocks the air hole 34, first keep the position of the baffle ring 45, and then reinsert the plug block 42 into the fixed block 43 along the slot 44, and pass through the limit block 41, so as to lock the fixed block 43 on the limit block 41. Because the limit block 41 is fixed on the fixing plate 36, the position of the limit block 41 is fixed and does not move. If the air hole 34 needs to be exposed again, the same operation can be used to expose the air hole 34.

[0035] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
