[0035] Unless otherwise defined, the terms used herein have the same meaning as commonly understood by those of ordinary skill in the field to which the present utility model belongs, and the terms should be understood to have a meaning consistent with the context of the related art and should not be understood in an idealized or overly formalized manner, except in cases where the present utility model is clearly defined.
[0036] As Figures 1 to 3 shown, an embodiment of a simple lake - area water - flow observation device bottom - mounted observation frame provided by the present utility model is composed of a circular chassis 1, six anti - settlement floating balls 2, an ADCP installation device 3, a bracket device 4 and two hoops 5.
[0037] The circular chassis 1 is a stainless - steel disc with a diameter of 0.8 m and a thickness of 1 cm. A number of water - passing holes 6 are evenly distributed on the circular chassis 1.
[0038] The diameter of the water - passing hole 6 does not exceed one - fifteenth of the diameter of the circular chassis 1 in proportion. During the implementation process, when the lake hydrodynamic force is very strong, the thickness of the circular chassis 1 can be appropriately increased to increase the weight and prevent the observation frame from being overturned by the water flow. When the underwater bottom is silt, the diameter of the chassis can be increased to prevent the observation frame from sinking.
[0039] The water through-hole 6 ensures direct contact between the lower mud surface of the circular chassis 1 and the water body, preventing the circular chassis 1 from being adsorbed to the mud surface under the action of underwater forces, which would otherwise require a greater force to extract the circular chassis 1 in the bottom-mounted state. At the same time, when extracting, it can also reduce the resistance of the water body.
[0040] The anti-settlement floating ball 2 is connected to the circular chassis 1 by a steel wire or a soft rope 7, and the steel wire or the soft rope can be selected according to the duration of the observation frame placed underwater. Generally, a steel wire is selected for long-term observation as it is corrosion-resistant; a soft rope is selected for short-term observation of about one week as it has a lower cost.
[0041] The anti-settlement floating ball 2 is a small spherical ball made of foam material with a central perforation. It is bound and connected through the adjacent water through-holes 6 in the circular chassis by a steel wire or a soft rope 7. There are six anti-settlement floating balls 2 in total, evenly distributed around the circular chassis 1, providing upward buoyancy, which can, to a certain extent, make the observation frame stable when placed on the bottom of the water and not easily tip over.
[0042] The center of the circular chassis 1 is fixedly connected to the ADCP installation device 3 by 2 bolts.
[0043] The ADCP installation device 3 consists of a detachable fixing device 8 and an ADCP installation cover. The detachable fixing device 8 is fixedly connected, for example, by welding, with two vertical connecting plates and a horizontal connecting plate. Among them, each end of the horizontal connecting plate is provided with a screw hole and is fixed to the circular chassis 1 by a bolt. A vertical cylindrical steel pipe with an internal thread at the upper end is welded in the middle of the two vertical connecting plates. The upper part of the ADCP installation cover is a ring distributed with 4 screw holes, and the lower end of the ring is integrally connected to two "U"-shaped stainless steel bars by welding to form an installation cover, and is connected to a vertical cylindrical steel pipe with an external thread at the lower end. Here, the connection is between a vertical cylindrical steel pipe with an internal thread and a vertical cylindrical steel pipe with an external thread, and they are rotationally docked to facilitate the replacement of the ADCP installation cover manufactured according to water flow observation devices of different sizes.
[0044] The internal thread at the upper end of the cylindrical steel pipe of the detachable fixing device 8 is connected and matched with the external thread at the lower end of the vertical cylindrical steel pipe on the ADCP installation cover. Tightening can fix the detachable fixing device 8 and the ADCP installation cover; obviously, if the upper end of the cylindrical steel pipe of the detachable fixing device 8 is provided with an external thread and the lower end of the vertical cylindrical steel pipe on the ADCP installation cover is provided with an internal thread, the cooperation of the movable connection structure can also be achieved.
[0045] The ADCP installation device 3 is suitable for installing and fixing the ADCP of the signature1000 (Jiaolong) type. The ADCP installation cover can change its size according to different device sizes, and is fixed by butt-joint of threaded pipes, which can be replaced at any time, and is very convenient and simple.
[0046] The circular chassis 1 is also connected to the bracket device 4 by 4 bolts.
[0047] The bracket device 4 is composed of two detachable fixing devices 8, two stainless steel right-angle steel pipes 41 and a semi-circular steel pipe 42. One end of each stainless steel right-angle steel pipe 41 is vertically fixed to the circular chassis 1 through a detachable fixing device 8, and the other end is fixedly connected to one end of the semi-circular steel pipe 42 by welding; the plane where the semi-circle of the semi-circular steel pipe 42 is located is parallel to the plane of the circular chassis 1. The detachable fixing device 8 is fixed by bolts passing through, and can connect steel pipes of different heights to adapt to the water flow observation at different water depths.
[0048] The hoop 5 is composed of a pair of stainless steel sheets. Each stainless steel sheet has two semi-circles of different sizes, and screw holes are respectively provided in the middle and both ends, and are connected and fixed to the circular chassis 1 by bolts, so that the small semi-circular part is fixed to the right-angle steel pipe 41 of the bracket device 4 by bolts, and the large semi-circular part is used to fix the flow measurement device (not shown in the figure for simplicity).
[0049] The structure adopted by the utility model is simple, the contact surface with the water body above the mud surface is small, the influence of the observation frame structure itself on the measured point flow field can be effectively reduced, and the effective space can be fully utilized, and multiple monitoring devices can be carried. The detachable fixing device is adopted to adapt to different application scenarios and is convenient and flexible to disassemble.
[0050] The structure of the utility model is light and simple, and it is very suitable as the installation frame of the water flow observation equipment in the low-flow lakes in the plain river network. Only two people are required for the launch and recovery operations.
[0051] The anti-settlement floating ball can effectively prevent the observation frame from being inverted in the water during the launch process, and prevent the situation that the circular chassis cannot land horizontally, and at the same time can increase the buoyancy to prevent the observation frame from settling.
[0052] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative labor. Therefore, the utility model is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the utility model should be within the protection scope of the utility model.
