The rain gauge is a traditional product, a water receiving port is made of a copper casting, and a cylinder body is formed by soldering a stainless steel plate.

The existing hydrological rain gauge is poor in dustproof effect, and when the existing hydrological rain gauge is placed in an open environment and is used for mobile phone rainwater, fallen leaves which are frequently withered fall into the rain gauge, so that the measurement effect is influenced; some add on the rain gauge and establish a dust screen, but the fallen leaves that wither and fall easily blocks up the collection mouth of rain gauge, influences the further collection of rainwater, and the rain gauge is collected data and is caused great error easily.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming the defect of prior art, the utility model aims at providing a hydrological rain gauge, the effectual current hydrological rain gauge of having solved influences the problem of measuring result because of fallen leaves easily.

The technical scheme of its solution is, the utility model discloses an upper and lower axial and upper end open-ended urceolus, the coaxial opening collecting vessel up that is equipped with of downside in the urceolus, the circular plate that is located the collecting vessel top is connected with in the urceolus dismantlement, axial cylinder pole about the circular plate upper end is equipped with, be equipped with spiral guide plate on the cylinder pole outer fringe face, the guide plate can with urceolus internal surface in close contact with, the guide plate lower extreme is equipped with vertical filter, set up a plurality of through-holes at its surface equipartition on the filter, set up the fan-shaped groove that is located the filter below.

Compared with the prior art, the beneficial effects of the utility model are that: the spiral guide plate that is equipped with can effectively reduce the influence that the fallen leaves were collected to the rainwater and are becoming, reduces measuring error, and filter and a plurality of through-hole that are equipped with can effectively prevent external article and get into the collecting vessel, and the inserted block and the baffle that are equipped with can strengthen the stability of this device, and the transparent plate that is equipped with, the staff of being convenient for know the condition of rainwater in the collecting vessel, this simple structure, the design is novel, convenient to use, the practicality is strong.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5 and give, including upper and lower axial and upper end open-ended urceolus 1, the coaxial opening collecting vessel 2 up that is equipped with of downside in the urceolus 1, the dismantlement is connected with the plectane 3 that is located the collecting vessel 2 top in the urceolus 1, axial cylinder pole 4 about the plectane 3 upper end is equipped with, be equipped with spiral guide plate 5 on the 4 outer fringe faces of cylinder pole, guide plate 5 can with 1 internal surface in close contact with of urceolus, guide plate 5 lower extreme is equipped with vertical filter 6, set up a plurality of through-holes 7 of its surperficial equipartition on the filter 6, set up on the plectane 3 and be located the filter.

In order to prevent the device from being soaked by external rainwater, the lower end of the outer cylinder 1 is provided with a fixing ring 9, and the fixing ring 9 is provided with a plurality of supporting legs 10 which are uniformly distributed along the circumferential direction of the fixing ring 9.

In order to enhance the stability of the device, the lower end of each supporting leg 10 is provided with an upper axial baffle plate 11 and a lower axial baffle plate 11, and the lower end of the baffle plate 11 is provided with a downward-pointed insertion block 12.

In order to measure rainwater in the collecting barrel 2 conveniently, the left side of the lower end of the collecting barrel 2 is provided with a liquid outlet pipe 13 in the vertical axial direction, and the lower end of the liquid outlet pipe 13 penetrates through the outer barrel 1 and is provided with a switch valve 14.

For better use effect, the collecting barrel 2 is made of transparent materials.

In order to facilitate the observation of the liquid level in the collecting barrel 2, the front end of the outer barrel 1 is provided with a rectangular groove 15 which is through from front to back, and a transparent plate 16 is arranged in the rectangular groove 15.

When the utility model is used, the device is firstly transported to the position where rainfall measurement is needed, then a plurality of inserting blocks 12 are inserted into soil, and the lower ends of a plurality of baffles 11 are contacted with the ground, thus completing the fixation of the device;

when the rain falls, rainwater at the opening of the outer barrel 1 enters the outer barrel 1 and drips to the upper end of the guide plate 5, the guide plate 5 is spiral, so that the rainwater gradually flows downwards along the upper surface of the guide plate 5, falling leaves float into the outer barrel 1 and then are positioned at the upper end of the guide plate 5, the collection of the rainwater cannot be influenced, the rainwater flows to the filter plate 6 and then flows to the circular plate 3 through the through holes 7, and then enters the collecting barrel 2 through the fan-shaped groove 8, and the filter plate 6 can effectively prevent external objects from entering the collecting barrel 2;
