Description

Technical Field

[0001] This utility model relates to the field of hydrological surveying technology, specifically to a support frame with an adjustable function. Background Technology

[0002] Hydrological surveying is a fundamental task in water resource management, flood and drought prevention, water conservancy project design, and ecological research. Its core lies in obtaining accurate and continuous hydrological data (such as water level, flow velocity, discharge, and water quality parameters). In actual field surveys, especially in complex terrains such as mountainous areas, canyons, riverbanks, or reservoir slopes, surveyors often face challenges with steep, rugged, and unstable slopes. These areas are often critical locations where hydrological information changes drastically and has a significant impact on engineering projects.

[0003] Currently, support frames are often used in the exploration process to provide a stable and reliable support structure for the installation of various hydrological sensors (such as water level gauges, flow meters, rain gauges, water quality probes, cameras, etc.), so as to achieve accurate and continuous acquisition of hydrological element data (such as water level, flow velocity, flow rate, water quality parameters, etc.).

[0004] However, the existing support frame has limited adjustment of the support rod position. When facing steep slopes, it may result in a single support rod being suspended in the air, making it difficult for the support frame to provide stable support for the hydrological sensor. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a support frame with an adjustable function to solve the problem that the position adjustment of the support rods of the existing support frame is limited, and when facing steep slopes, a single support rod may be suspended in the air, making it difficult for the support frame to provide stable support for the hydrological sensor.

[0006] This utility model is achieved through the following technical solution:

[0007] An adjustable support frame includes a mounting base and multiple support rods. A ring-shaped sliding rod is fixedly connected to the mounting base, and a slider is slidably connected to the sliding rod. The number of sliders is equal to the number of support rods. A first locking assembly is installed between each of the sliders and the mounting base. The multiple support rods are rotatably connected to their corresponding sliders, and a second locking assembly is installed between each of the multiple support rods and their corresponding sliders.

[0008] Furthermore, the first locking assembly includes multiple connecting plates that are fixedly connected to multiple sliders respectively. Each of the multiple connecting plates has a first through hole, and a limiting rod passes through each of the multiple first through holes. The mounting base has multiple limiting holes that are adapted to the limiting rods. The multiple limiting holes are evenly distributed around the central axis of the mounting base. When the slider and the mounting base are locked, the limiting rod passes through the first through hole and the corresponding limiting hole.

[0009] Furthermore, each of the aforementioned limiting rods is fixedly connected to a handle.

[0010] Furthermore, the end of the limiting rod inserted into the corresponding limiting hole is a threaded end, and all of the multiple limiting holes are threaded holes. When the slider is locked to the mounting base, the limiting rod passes through the first through hole and is threadedly connected to the mounting base.

[0011] Furthermore, the second locking assembly includes multiple screws, which are respectively fixedly connected to the two side walls of the multiple support rods near the slider end. Each of the multiple sliders has a notch at the end near the support rod, and a second through hole communicating with the notch is formed on the side wall of each slider. The diameter of the screw is smaller than the diameter of the second through hole, and the multiple screws pass through the corresponding second through hole. A first nut is fitted on each of the multiple screws. When the slider and support rod are locked, the first nut is threadedly connected to the corresponding screw.

[0012] Furthermore, multiple connecting rods are fixedly connected to the mounting base, and the ends of the multiple connecting rods away from the mounting base are fixedly connected to the slide rod.

[0013] Furthermore, the support rod has a hollow internal structure, and the end of the support rod away from the slider is open. An adjusting rod is slidably connected inside the support rod, and a third locking assembly is provided between the adjusting rod and the support rod.

[0014] Furthermore, the third locking assembly includes a second nut sleeved on the adjusting rod. The open end of the support rod has multiple first grooves extending along its length. The open end of the support rod is cut with an external thread that matches the second nut. A protrusion is fixedly connected to the lower end of the second nut. The protrusion is annular and gradually tapers from top to bottom. When the support rod and the adjusting rod are locked, the second nut is threadedly connected to the support rod, and the protrusion presses against the side wall of the support rod, causing the first grooves to shrink.

[0015] Furthermore, a foot nail is installed at the end of the adjusting rod away from the support rod.

[0016] Furthermore, a second groove is provided at the end of the adjusting rod away from the support rod, and a rotating shaft is rotatably connected in the second groove. The end of the foot nail near the adjusting rod is fixedly connected to the rotating shaft.

[0017] The beneficial effects of this utility model are as follows:

[0018] This adjustable support frame allows the support rods to slide along the slide bar via a slider, making it more adaptable to steep slopes, reducing the probability of a single support rod being suspended in the air, and increasing the probability of all support rods reliably contacting the ground, thus making it easier for the support frame to provide stable support for hydrological sensors.

[0034] Please see Figure 1-7This utility model provides a technical solution: a support frame with an adjustable function, including a mounting base 1 and multiple support rods 2. A ring-shaped sliding rod 3 is fixedly connected to the mounting base 1, and a slider 4 is slidably connected to the sliding rod 3. Multiple connecting rods 16 are fixedly connected to the mounting base 1, and the ends of the multiple connecting rods 16 away from the mounting base 1 are fixedly connected to the sliding rod 3. The number of sliders 4 is equal to the number of support rods 2. A first locking assembly 5 is installed between each of the multiple sliders 4 and the mounting base 1. The multiple support rods 2 are rotatably connected to the corresponding sliders 4. A second locking assembly 6 is installed between each of the multiple support rods 2 and the corresponding sliders 4.

[0035] The first locking assembly 5 includes multiple connecting plates 7 that are fixedly connected to multiple sliders 4 respectively. Each of the multiple connecting plates 7 has a first through hole 8. Each of the multiple first through holes 8 has a limiting rod 9 passing through it. The mounting base 1 has multiple limiting holes 10 that are adapted to the limiting rod 9. The multiple limiting holes 10 are evenly distributed around the central axis of the mounting base 1. When the slider 4 is locked to the mounting base 1, the limiting rod 9 passes through the first through hole 8 and the corresponding limiting hole 10.

[0036] The end of the limiting rod 9 that is inserted into the corresponding limiting hole 10 is a threaded end. All of the limiting holes 10 are threaded holes. When the slider 4 is locked to the mounting base 1, the limiting rod 9 passes through the first through hole 8 and is threadedly connected to the mounting base 1.

[0037] The second locking assembly 6 includes multiple screws 12, which are respectively fixedly connected to the two side walls of the multiple support rods 2 near the slider 4. Each of the multiple sliders 4 has a notch 13 at the end near the support rod 2. The side walls of the multiple sliders 4 have a second through hole 14 communicating with the notch 13. The diameter of the screw 12 is smaller than the diameter of the second through hole 14. The multiple screws 12 pass through the corresponding second through hole 14. Each of the multiple screws 12 is fitted with a first nut 15. When the slider 4 and the support rod 2 are locked, the first nut 15 is threadedly connected to the corresponding screw 12.

[0038] In this design: multiple connecting rods 16 are fixedly connected to the mounting base 1, and the slide rod 3 is fixedly connected to the mounting base 1 via the multiple connecting rods 16. The slider 4 slides along the length of the slide rod 3 and is located between two adjacent connecting rods 16.

[0039] By fixing multiple connecting plates 7 to multiple sliders 4 respectively, each connecting plate 7 has a first through hole 8, and the mounting base 1 has multiple limiting holes 10 that are adapted to the limiting rod 9. The multiple limiting holes 10 are evenly distributed around the central axis of the mounting base 1 to facilitate the fixing of the slider 4 to the mounting base 1 at multiple positions. The limiting holes 10 are threaded holes. When the slider 4 and the mounting base 1 are locked, the limiting rod 9 passes through the first through hole 8 and is threadedly connected to the corresponding limiting hole 10. After the limiting rod 9 is removed from the first through hole 8 and the corresponding limiting hole 10, the slider 4 and the mounting base 1 are in an unlocked state.

[0040] By fixing multiple screws 12 to the two side walls of multiple support rods 2 near the slider 4, and opening notches 13 at the ends of the sliders 4 near the support rods 2, and opening second through holes 14 communicating with the notches 13 on the side walls of the sliders 4, the diameter of the screws 12 is smaller than the diameter of the second through holes 14, allowing the screws 12 to rotate around their central axis. The multiple screws 12 pass through the corresponding second through holes 14, and each screw 12 is fitted with a first nut 15. When the slider 4 and the support rod 2 are locked, the first nut 15 is threadedly connected to the corresponding screw 12. After loosening the first nut 15, the slider 4 and the support rod 2 are in an unlocked state, and the support rod 2 can rotate around the central axis of the screw 12.

[0041] How to use:

[0042] Step 1: Loosen the first nut 15, the slider 4 and the support rod 2 are in the unlocked state, and the multiple support rods 2 are opened to a suitable angle.

[0043] Step 2: Remove the limiting rod 9 from the first through hole 8 and the corresponding limiting hole 10. The slider 4 and the mounting base 1 are in the unlocked state. Move the multiple support rods 2 around the length direction of the slider 3 so that they rotate around the central axis of the mounting base 1 to a suitable position.

[0044] Step 3: The first nut 15 is threadedly connected to the corresponding screw 12, so that the slider 4 and the support rod 2 are locked. The limiting rod 9 is then threadedly connected through the first through hole 8 to the corresponding limiting hole 10, so that the slider 4 and the mounting base 1 are locked.

[0045] Compared to existing technologies, the sliding adjustment of the support rod along the slide bar 3 by the slider 4 can better adapt to steep slopes, reduce the probability of a single support rod 2 being suspended in the air, increase the probability of all support rods 2 reliably contacting the ground, and make the support frame more likely to provide stable support for the hydrological sensor.

[0046] In this embodiment, handles 11 are fixedly connected to each of the multiple limiting rods 9.

[0047] In this design, handles 11 are fixedly connected to multiple limiting rods 9. This increases friction, facilitates the rotation and removal of the limiting rods 9, and improves operational efficiency.

[0048] In this embodiment: the support rod 2 has a hollow structure inside, the end of the support rod 2 away from the slider 4 is open, an adjusting rod 17 is slidably connected inside the support rod 2, and a third locking component is provided between the adjusting rod 17 and the support rod 2.

[0049] The third locking assembly includes a second nut 18 sleeved on the adjusting rod 17. The open end of the support rod 2 has multiple first grooves 19 extending along its length. The open end of the support rod 2 is cut with an external thread 20 that matches the second nut 18. The lower end of the second nut 18 is fixedly connected to a protrusion 24. The protrusion 24 is annular and gradually tapers from top to bottom. When the support rod 2 and the adjusting rod 17 are locked, the second nut 18 is threadedly connected to the support rod 2. The protrusion 24 presses against the side wall of the support rod 2, causing the first grooves 19 to contract.

[0050] In this design: the support rod 2 is hollow, with an open end away from the slider 4. An adjusting rod 17 is slidably connected inside the support rod 2, and a second nut 18 is fitted onto the adjusting rod 17. Multiple first grooves 19 extending along the length of the open end of the support rod 2 are formed. An external thread 20 adapted to the second nut 18 is cut into the open end of the support rod 2. A protrusion 24 is fixedly connected to the lower end of the second nut 18. The protrusion 24 is annular and gradually tapers from top to bottom. When the support rod 2 and the adjusting rod 17 are locked, the second nut 18 is threadedly connected to the support rod 2, and the protrusion 24 presses against the side wall of the support rod 2, causing the first grooves 19 to contract.

[0051] In use, first loosen the second nut 18 to unlock the support rod 2 and the adjusting rod 17. Pull the adjusting rod 17 to the ground, then thread the second nut 18 onto the support rod 2. The protrusion 24 presses against the side wall of the support rod 2, causing the first groove 19 to contract. This locks the support rod 2 and the adjusting rod 17.

[0052] Each support rod 2 can be independently adjusted in length to handle rugged terrain with significant height differences (such as boulders or stepped riverbanks). This further reduces the probability of a single support rod 2 becoming suspended or the platform tilting due to uneven ground.

[0053] In this embodiment, a foot nail 21 is installed at the end of the adjusting rod 17 away from the support rod 2.

[0054] The adjusting rod 17 has a second groove 22 at the end away from the support rod 2. A rotating shaft 23 is rotatably connected in the second groove 22. The foot nail 21 is fixedly connected to the rotating shaft 23 at the end near the adjusting rod 17.

[0055] In this design: a second groove 22 is provided at the end of the adjusting rod 17 away from the support rod 2, and a rotating shaft 23 is rotatably connected in the second groove 22, with foot nails 21 fixedly connected to the rotating shaft 23.

[0056] When in use, rotate the foot spike 21 so that the tip of the foot spike 21 is outside the second groove 22 and inserted into the ground, improving the stability of the adjusting rod 17 with respect to the ground. After the exploration is completed, rotate the foot spike 21 so that the tip of the foot spike 21 is inside the second groove 22, reducing the probability of the foot spike 21 accidentally scratching personnel during transportation.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
