Description

Initial rainwater collection system

Technical Field

The utility model relates to an environmental monitoring field especially relates to an initial stage rainwater collection system.

Background

Rainwater collection is one of the important means for knowing the climate change of the area. While the rain water can be contaminated by floating dust, flying microorganisms and the like in the atmosphere in the falling process. As the time of raining becomes longer, the content of the components of the initial rainwater, the middle rainwater and the later rainwater changes greatly. The collection is troublesome when scientists need to analyze the rainwater in different periods respectively. Particularly, the collection of initial rainwater requires manual sealing operation in the rain process or remote control by using an electronic device. Since the rain environment is wet, the sealing requirements for the electronics are high, and the equipment costs are further increased. At present, no mechanical initial rainwater collecting device exists.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide an initial rainwater collection system.

The utility model relates to an initial rainwater collecting device, which comprises a box body with an open opening at the upper end and a cover body for sealing the open opening; a beaker is arranged below the open hole in the box body; one end of the cover body is hinged with the upper part of the box body through a hinge, and the other end of the cover body freely extends; a cantilever extends upwards from one side of the upper part of the box body, which is far away from the cover body, and a fixed pulley is arranged at the free end of the cantilever; a rope is spanned on the fixed pulley, one end of the rope is connected with the free end of the cover body, and the other end of the rope is connected with a bucket.

An initial stage rainwater collection system, its advantage lies in, through the total weight change of well-bucket at the rainy in-process, can stimulate the lid and seal the operation after the certain time of raining. Manual intervention in rain is not needed, and any electronic equipment is not needed. Simple structure, low cost, and is especially suitable for the suburb environment in the wilderness.

The box be equipped with a support arm below the hinge, support arm one end and box lateral wall fixed connection, the other end upwards extends and is used for preventing that the lid from crossing to turn over.

The bottom of the box body is provided with a drain hole for draining accumulated water in the box body.

The side wall of the box body far away from the hinge is higher than the horizontal position of the hinge, the length of the cover body is larger than the width of the box body, and the cover body is obliquely arranged when the open hole is closed.

Detailed Description

As shown in fig. 1, the initial rainwater collecting device of the present invention includes a box 10 having an open top and a cover 11 for closing the open top; a beaker 20 is arranged below the open mouth in the box body 10; one end of the cover body 11 is hinged with the upper part of the box body 10 through a hinge, and the other end of the cover body freely extends; a cantilever 12 extends upwards from one side of the upper part of the box body 10 far away from the cover body 11, and a fixed pulley 13 is arranged at the free end of the cantilever 12; a rope is spanned on the fixed pulley 13, one end of the rope is connected with the free end of the cover body 11, and the other end of the rope is connected with a bucket 14. The hinge generally has a certain over-turning stopping function, and in the embodiment, the hinge only needs to stop the cover body 11 from turning outwards not too much to influence the pulling of the bucket 14. The eversion angle may be 5 ° to 19 °. The cover 11 may be made of iron or plastic.

Box 10 below the hinge be equipped with a support arm 15, support arm 15 one end and box 10 lateral wall fixed connection, the other end upwards extends and is used for preventing that lid 11 from turning over excessively. The turning angle can be controlled more accurately through the combined action of the hinge and the supporting arm 15.

The bottom of the box body 10 is provided with a drain hole for draining accumulated water in the box body 10. Preventing rainwater infiltrating into the interior of the case 10 from being excessively high in level to contaminate the sample in the beaker 20.

The side wall of the box body 10 far away from the hinge is higher than the horizontal position of the hinge, the length of the cover body 11 is larger than the width of the box body 10, and the cover body 11 is obliquely arranged when the open hole is closed. The inclined condition helps to prevent rain water from seeping into the interior of the tank 10 and flowing away from the surface more quickly.

A primary rainwater collection system theory of operation as follows: an empty beaker 20 is placed in the housing 10 before it rains, and the housing 10 is then placed in the target area for sample collection. The cover 11 is opened and the cover 11 is turned inside out to an angle, for example 16, and supported by the support arms 15. Ensuring that there is no water accumulation in the bucket 14. Since the bucket 14 is empty, the total weight is not so large that the cover 11 is not pulled by the rope. When it begins to rain, the rain falls into the bucket 14 and the beaker 20, respectively. The total weight of the tub 14 is slowly increased until it is more than the weight by which the cover 11 can be pulled. The bucket 14 filled with water pulls the lid 11 through the rope and the fixed pulley 13, and the lid 11 is rotated above the beaker 20. When the cover 11 rotates in the vertical direction, the opening of the box 10 is automatically closed by the gravity of the cover, so that the box 10 can be automatically closed at the early stage of rain, as shown in fig. 2. The collection amount in the beaker 20 can be determined by the buckets 14 with different calibers, and the smaller the calibers of the buckets 14 are, the longer the time required for pulling the cover body 11 is, the more the collection amount in the beaker 20 is.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
