Abstract
Description
Technical Field
[0001] This utility model relates to the field of rainwater collection technology, specifically to an outdoor rainwater collection and sampling device. Background Technology
[0002] Environmental monitoring typically requires rainwater testing. Rainwater is collected using sampling equipment during rainfall. Current rainwater sampling equipment uses a sampling tube to collect rainwater directly for convenience. However, since it is placed outdoors, it is easy for people to throw debris into the sampling tube.
[0003] Therefore, in order to correct the above-mentioned defects, we propose an outdoor rainwater collection and sampling device. Utility Model Content
[0004] The technical problem solved by this utility model is to provide an outdoor rainwater collection and sampling device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor rainwater collection and sampling device, comprising a sampling cylinder and a collection port at the top of the sampling cylinder. The sampling cylinder consists of an upper cylinder and a lower cylinder, which are threadedly connected and interconnected. The depth of the lower cylinder is greater than the depth of the upper cylinder. The collection port is funnel-shaped, and a sphere is movably placed at the internal outlet position of the collection port. The diameter of the sphere is greater than the outlet diameter of the collection port. A pressure plate is fixed on the inner sidewall of the collection port, and the pressure plate is positioned above the sphere and maintains a distance of 5mm-10mm.
[0006] Furthermore, the pressure plate is inclined.
[0007] Furthermore, the outlet of the collection port is connected to a vertical guide pipe.
[0008] Furthermore, an inner water collection cylinder is placed inside the lower cylinder.
[0009] Furthermore, a positioning ring is installed at the bottom of the lower cylinder, and the bottom of the inner water collecting cylinder is inserted into the positioning ring.
[0010] Furthermore, the outer wall of the inner water collection cylinder is provided with scale lines.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the sampling tube in this utility model has a simple structure and does not contain a complex structure. When collecting rainwater, it can effectively isolate impurities and prevent them from entering the interior. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides a technical solution:
[0020] Please see Figure 1-4 An outdoor rainwater sampling device includes a sampling cylinder and a sampling port 3 at the top of the sampling cylinder. The sampling cylinder consists of an upper cylinder 2 and a lower cylinder 1, which are threaded together and interconnected. The depth of the lower cylinder 1 is greater than the depth of the upper cylinder 2. The sampling port 3 is funnel-shaped. A sphere 6 is movably placed at the outlet position inside the sampling port 3. The diameter of the sphere 6 is greater than the outlet diameter of the sampling port 3. A pressure plate 5 is fixed on the inner side wall of the sampling port 3. The pressure plate 5 is above the sphere 6 and maintains a distance of 5mm-10mm.
[0021] Rainwater enters the sampling tube through the collection port 3. When the rainwater enters the collection port 3, the outlet of the collection port 3 is first blocked by the sphere. When the rainwater inside the collection port 3 reaches a certain depth, the sphere 6 will start to float up. At the same time, the pressure plate 5 will press down the sphere 6, so that the sphere 6 and the outlet of the collection port 3 maintain a small gap. The rainwater seeps down through this gap, thus isolating impurities.
[0022] The pressure plate 5 is inclined, which can play a role in backflow and at the same time prevent the ball 6 from falling out of the gap between the pressure plate 5 and the other inner wall of the collection port 3.
[0023] In addition, an inner water collection cylinder 8 is placed separately inside the sampling cylinder, and the outlet of the sampling port 3 is connected to a vertical guide pipe 4, so that rainwater can directly enter the inner water collection cylinder 8 along the guide pipe 4.
[0024] The lower cylinder 1 has a positioning ring 7 installed at its inner bottom. The bottom of the inner water collecting cylinder 8 is inserted into the positioning ring 7. The positioning ring 7 is used to fix the inner water collecting cylinder 8. When the inner water collecting cylinder 8 is removed, the upper cylinder 2 can be rotated off the lower cylinder 1. The positioning ring 7 can be made of a high-density material to act as a counterweight and prevent the entire sampling cylinder from tipping over due to its top-heavy design.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
