Description

Technical Field

[0001] This utility model relates to the field of water sample collection technology, specifically to a bridge water body sample collection bracket. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality status. Aquatic organism monitoring mainly studies the responses of aquatic organisms to the water environment and water pollution processes, as well as the relationship between human disturbance and ecological environment changes. It analyzes the disturbance factors and effects that cause changes in the lake ecological environment, the lake water environment, and the water quality development trend, providing a scientific basis for the restoration and reconstruction of damaged ecosystems, the coordination of the relationship between humans and nature, ecosystem protection, and sustainable development. Both water quality monitoring and aquatic organism monitoring require the collection of water samples from the rivers and lakes to be tested.

[0003] In current technology, water sample collection relies solely on water samplers. Sampling in typical rivers requires venturing into the center of the river. If the water is deep, wading is not feasible, necessitating the use of boats or sampling from bridges. However, many smaller rivers lack readily available boats, and some waterways lack suitable navigation conditions. Therefore, sampling is often conducted from the middle of bridges spanning the river. This ensures accurate sampling location but increases the difficulty of the process. Bridges are typically fencing off for safety. Generally, the fences are high and wide, and some bridges have pipelines crossing the river on both sides of the fences. When collecting water from the bridge, due to the height of the bridge, the water sampler is tied with a rope and then lowered vertically into the water from the bridge. This requires crossing these obstacles to lower the water sampler into the water, which requires leaning out of the body to lower it. Although it is possible to use a throwing method or iron bar to lower the water sampler over the obstacles into the water, it is still difficult to retrieve the water sampler smoothly when lifting it up. This requires leaning out of the body to retrieve it, which is very dangerous. Utility Model Content

[0004] The purpose of this invention is to reduce the difficulty of water sample collection on bridges in rivers, lakes, and other waterways, improve safety, reduce sampling time, and effectively improve the accuracy of sample collection results.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A bridge water body sample collection bracket includes a fixed bracket, the fixed bracket being designed in an L-shape, and also includes adjustable clamping and telescopic mechanisms connected to the fixed bracket. The two fixed brackets are distributed in parallel at intervals, and a first connecting plate and a second connecting plate that are parallel to each other are fixedly connected between the two fixed brackets.

[0007] The adjustable clamp includes a knob and an adjustment frame. The adjustment frame is movably sleeved on the fixed bracket. The knob is rotated on the outside of the second connecting plate and drives the adjustment frame to slide horizontally between the first connecting plate and the second connecting plate.

[0008] The telescopic mechanism includes hydraulic rods and a telescopic frame. The two hydraulic rods are horizontally fixed to the inner rear ends of two fixed supports through their fixed ends, and the telescopic ends of the hydraulic rods are fixed to the telescopic frame.

[0009] Furthermore, a horizontally distributed screw is fixed to the knob, the end of the screw rotates through the second connecting plate and is rotatably connected to the first connecting plate, and the adjusting bracket is threadedly connected to the screw.

[0010] Furthermore, the adjustment frame is designed as an inverted U-shaped structure, with two through holes on both sides, through which the adjustment frame is slidably fitted onto the fixed bracket.

[0011] Furthermore, the telescopic frame is configured as a horizontally distributed U-shaped structure, and the fixed bracket is provided with horizontally distributed sliding grooves, and the two ends of the telescopic frame are adapted to slide within the sliding grooves.

[0012] Furthermore, a limiting block is fixedly connected inside the sliding groove, and the telescopic frame is provided with a horizontally distributed limiting through groove that runs through the telescopic frame. The limiting block and the limiting through groove are slidably adapted to each other.

[0013] Furthermore, a mounting frame is fixedly connected to the front end of the telescopic frame, and a pulley is rotatably connected to the mounting frame.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] 1. Equipped with a telescopic mechanism, the telescopic frame is extended and retracted by a hydraulic rod, and then the rope carrying the sampler extends to the upper part of the water surface through the pulley, which facilitates the control of the sampler to descend vertically for collection. The telescopic mechanism can reduce the occurrence of accidents and greatly increase the safety of users. There is no need to stick out of the body or climb onto the bridge railing to collect water samples. The device can be safely operated from inside the bridge railing. As long as the bracket is installed, water samples can be collected safely.

[0016] 2. Water samples from rivers and lakes are generally collected in the middle of the river channel, where the water is less disturbed by the environment, resulting in more representative samples. However, many large rivers are wide, and the bridges spanning them are long with wide railings, making it difficult to lower the water sampler. Lifting it can also cause it to touch the pipelines along the bridge, posing a danger. With an adjustable clamp, the spacing between the adjustment frame and the fixing frame can be adjusted according to the width of different bridge railings, allowing them to be adapted to bridge railings of different widths (less than 50cm) and installed on the bridge railing.

[0026] like Figure 1-5 As shown, a bridge water body sample collection bracket includes a fixed bracket 1, which is designed with an L-shaped structure. It also includes an adjustable clamp 3 and a telescopic mechanism 2. The adjustable clamp 3 and the telescopic mechanism 2 are both connected to the fixed bracket 1. The two fixed brackets 1 are distributed parallel to each other at intervals. A first connecting plate 101 and a second connecting plate 102 are fixedly connected between the two fixed brackets 1. The first connecting plate 101 and the second connecting plate 102 are both perpendicular to the fixed bracket 1 and are distributed parallel to each other at intervals.

[0027] The adjustable clamp 3 includes a knob 304 and an adjustment frame 301. The adjustment frame 301 is sleeved on the fixed bracket 1. The knob 304 is rotatably located on the outside of the second connecting plate 102 and drives the adjustment frame 301 to slide horizontally between the first connecting plate 101 and the second connecting plate 102. The knob 304 is fixedly connected to a screw 303. The end of the screw 303 rotatably passes through the second connecting plate 102 and is rotatably connected to the first connecting plate 101. The adjustment frame 301 is threadedly connected to the screw 303. The adjustment frame 301 is designed with an inverted U-shaped structure. The adjustment frame 301 has two spaced through holes 302. The adjustment frame 301 is slidably sleeved on the fixed bracket 1 through the through holes 302. By rotating the knob 304, the adjustment frame 301 is driven to move horizontally on the fixed bracket 1, thereby adjusting the distance between the adjustment frame 301 and the vertical bar of the fixed bracket 1, thus adapting to the width of various bridge railings.

[0028] The telescopic mechanism 2 includes hydraulic rods 201 and a telescopic frame 202. Two hydraulic rods 201 are horizontally distributed in two fixed supports 1. The hydraulic rods 201 drive the telescopic frame 202 to slide horizontally at the front end of the fixed supports 1. The telescopic frame 202 is a horizontally distributed U-shaped structure. The fixed supports 1 are provided with sliding grooves 103. Both ends of the telescopic frame 202 slide within the sliding grooves 103 and are fixedly connected to the telescopic ends of the hydraulic rods 201. Limiting blocks 104 are fixedly connected within the sliding grooves 103. The telescopic frame 202... A limiting groove 203 is provided that is horizontally distributed and runs through the telescopic frame 202. The limiting block 104 is slidably adapted to the limiting groove 203 to prevent the telescopic frame 202 from sliding out of the front end of the fixed bracket 1. The front end of the telescopic frame 202 is fixedly connected to the mounting bracket 204. A pulley 205 is rotatably connected to the mounting bracket 204 to prevent wear during telescopic movement. The telescopic frame 202 is driven to extend from the front end of the fixed bracket 1 by the hydraulic rod 201, thereby causing the pulley 205 to drive the telescopic collector connected to it to move forward to the water surface, preventing the collector from colliding with the outer edge of the bridge when it descends.

[0029] In use, the fixed bracket 1 is placed on the bridge railing, with its vertical end touching the inner side of the railing. Depending on the width of the railing (less than 50cm), the knob 304 is rotated, causing the screw 303 to rotate, which in turn moves the adjusting frame 301 horizontally on the fixed bracket 1, bringing it to the outer side of the railing (the adjustable frame 301 is suitable for railing widths less than 50cm). This establishes the fixed bracket 1 on the railing. Based on the horizontal distance between the railing and the water surface, the hydraulic rod 201 drives the telescopic frame 202 forward, causing the pulley 205 to move horizontally to the vertical upper end of the water surface. Then, a collector (such as a bucket) can be lowered into the water using a rope for sampling. Finally, the telescopic frame is pulled up to collect the water sample.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
