Abstract
Description
Technical Field
[0001] This utility model relates to the field of water body monitoring technology, specifically an automatic sediment flow monitoring device. Background Technology
[0002] Sediment testing, a type of hydrological testing, broadly refers to the observation and measurement of the form, quantity, and evolution of sediment movement with water flow in a watershed and body of water. It typically includes measurements of suspended sediment transport rate, bed sediment transport rate, riverbed sediment determination, and analysis of sediment particle size distribution. Constructing reservoirs on rivers requires consideration of sediment deposition to determine their service life; river channel regulation, levee construction, and navigation channel management all necessitate the study of river sediment transport patterns; irrigation and water diversion projects require consideration of the amount of sediment entering the canal and the hydraulic conditions to prevent erosion and siltation; and soil and water conservation projects require research into watershed sediment production processes. Sediment testing is of significant importance in many aspects of human economic activities.
[0003] Sediment analyzers are commonly used in the process of monitoring sediment. These analyzers include suspended sediment samplers, bed sediment samplers, riverbed sediment samplers, and isotope sediment analyzers. Sediment analyzers can determine the sediment content and sediment particle diameter in water bodies.
[0004] Patent document CN221280371U discloses an automatic sediment flow monitoring device, including a sediment analyzer, a mounting frame, a level sensor, a lifting assembly, and a controller. The sediment analyzer, level sensor, lifting assembly, and controller are all mounted on the mounting frame. The sediment analyzer, level sensor, and lifting assembly are electrically connected to the controller. The lifting assembly is used to move the sediment analyzer and level sensor up and down. This invention can automatically adjust the position of the sediment analyzer in the water body, reducing the workload of manual intervention.
[0005] While the existing technology allows for adjustment of the height of the sediment meter, it still requires mechanical lifting and lowering when the water level changes, which is inconvenient. Therefore, a new automatic sediment flow monitoring device is proposed to optimize the existing technology. Utility Model Content
[0006] The purpose of this invention is to provide an automatic sediment flow monitoring device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An automatic sediment flow monitoring device includes a floating disc. A guide sleeve is fixedly connected through the middle of the floating disc. A threaded rod adapted to the guide sleeve slides through the guide sleeve. A protective frame is fixedly connected to the bottom end of the threaded rod. A sediment analyzer is fixedly installed on the bottom inner side of the protective frame. The sediment analyzer is an existing commercially available product. A threaded sleeve is rotatably connected to the top surface of the guide sleeve. A worm gear is fixedly connected to the outer side of the threaded sleeve. A worm is provided on the outer side of the worm gear and engages with it for transmission. The worm is rotatably installed on the top surface of the floating disc. A handle is fixedly connected to the end of the worm.
[0009] As a further embodiment of this utility model: a sliding sleeve is fixedly connected to the circumference of the floating plate, and vertical rods slide through the sliding sleeve. The bottom ends of the vertical rods are fixedly connected to a fixing plate, which is fixed to the bottom of the riverbed.
[0010] As a further improvement of this utility model: the top of the vertical rod is fixedly connected to a top plate, and a warning light is fixedly installed on the top plate.
[0011] As a further improvement of this utility model: an ultrasonic water level monitor is fixedly connected to the bottom edge of the top plate. The ultrasonic water level monitor is an existing product that is currently on the market. The water level is monitored by measuring the distance between the ultrasonic water level monitor and the water surface.
[0012] As a further improvement of this utility model: the upper and lower parts of the side wall of the floating plate are respectively fixedly connected to air inlet and outlet pipes and water inlet and outlet pipes. Valves are installed on both the air inlet and outlet pipes and the water inlet and outlet pipes. The air inlet and outlet pipes can be pumped and inflated by connecting an external air pump.
[0013] As a further embodiment of this utility model: a keyway is provided on the threaded rod, and a convex key is fixedly connected to the inner wall of the guide sleeve. The convex key is inserted into the keyway and slidably connected with the keyway. Through the cooperation of the keyway and the convex key, the threaded rod is slidably connected in the guide sleeve and forms a rotation limit.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model uses a floating plate to mount the sand measuring instrument, so that the floating plate always stays on the water surface during the rise and fall of the water level. The sand measuring instrument stays in the water body directly with the floating plate, without the need for additional operation, making monitoring more convenient.
[0016] 2. This utility model uses a rotating handle to rotate a worm gear, which in turn drives a threaded sleeve to rotate. Under the guidance of a guide sleeve, the threaded rod is driven to rise or fall, thereby controlling the depth at which the sand measuring instrument installed in the protective frame sinks into the water body, adapting to the monitoring of sediment flow at different water depths.
[0017] 3. This utility model guides the floating disc by using a vertical rod and a sliding sleeve, effectively preventing the floating disc from drifting away from the monitoring area.
[0018] 4. This utility model can draw air into and inflate the floating plate through the air inlet and outlet pipes, and together with the water inlet and outlet pipes, it can create the effect of injecting water into the floating plate or discharging water outward, thereby controlling the buoyancy of the floating plate.

[0023] 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.
[0024] Please see Figures 1-3In this embodiment of the present invention, an automatic sediment flow monitoring device includes a floating plate 1. A guide sleeve 2 is fixedly connected through the middle of the floating plate 1. A threaded rod 3 adapted to the guide sleeve 2 slides through the guide sleeve 2. The threaded rod 3 has scale lines and a keyway 19. A protruding key 20 is fixedly connected to the inner wall of the guide sleeve 2. The protruding key 20 is inserted into the keyway 19 and slidably connected to the keyway 19. The cooperation between the keyway 19 and the protruding key 20 allows the threaded rod 3 to slide within the guide sleeve 2 and form a rotation limit. A protective frame 4 is fixedly connected to the bottom end of the threaded rod 3. A sand measuring instrument 5 is fixedly installed on the bottom inner side of the protective frame 4. The sand measuring instrument 5 is an existing commercially available product. A threaded sleeve 6 is rotatably connected to the top surface of the guide sleeve 2. A worm gear 7 is fixedly connected to the outer side of the threaded sleeve 6. A worm 8 meshes with the worm gear 7 on the outer side of the worm gear 7. The worm 8 is rotatably installed on the top surface of the floating plate 1. A handle 9 is fixedly connected to the end of the worm 8.
[0025] The sand measuring instrument 5 is floated by the float 1, so that the float 1 always floats on the water surface during the rise and fall of the water level. The sand measuring instrument 5 stays in the water body directly with the float 1, without the need for additional operation, making monitoring more convenient.
[0026] Rotating the worm 8 via the handle 9 drives the threaded sleeve 6 to rotate via the worm wheel 7, which in turn drives the threaded rod 3 to rise or fall under the guidance of the guide sleeve 2, thereby controlling the depth to which the sand measuring instrument 5 installed in the protective frame 4 sinks into the water body, adapting to the monitoring of sediment flow at different water depths.
[0027] A sliding sleeve 10 is fixedly connected to the circumference of the floating plate 1. Vertical rods 11 slide through the sliding sleeve 10. The bottom ends of the vertical rods 11 are fixedly connected to a fixing plate 12, which is fixed to the bottom of the riverbed.
[0028] The vertical rod 11, in conjunction with the sliding sleeve 10, guides the floating of the floating disk 1, effectively preventing the floating disk 1 from drifting away from the monitoring area.
[0029] The top of the vertical rod 11 is fixedly connected to the top plate 13, and a warning light 14 is fixedly installed on the top plate 13.
[0030] The warning light 14 serves as a warning light, making the device more easily visible and preventing collisions.
[0031] An ultrasonic water level monitor 15 is fixedly connected to the bottom edge of the top plate 13. The ultrasonic water level monitor 15 is an existing product on the market, and the water level is monitored by the distance between the ultrasonic water level monitor 15 and the water surface.
[0032] The upper and lower parts of the side wall of the floating roof 1 are respectively fixedly connected to the air inlet / outlet pipe 16 and the water inlet / outlet pipe 17. Valves 18 are installed on both the air inlet / outlet pipe 16 and the water inlet / outlet pipe 17. The air inlet / outlet pipe 16 can be pumped and inflated by an external air pump.
[0033] Air can be drawn in and inflated into the floating plate 1 through the air inlet / outlet pipe 16, and together with the water inlet / outlet pipe 17, water can be injected into or discharged from the floating plate 1, thereby controlling the buoyancy of the floating plate 1.
[0034] The sand measuring instrument 5, the warning light 14, and the ultrasonic water level monitor 15 are all externally powered and connected to external monitoring and control equipment.
[0035] The working principle of this utility model is as follows:
[0036] In use, air can be drawn in and inflated into the float 1 through the air inlet / outlet pipe 16, which, together with the water inlet / outlet pipe 17, creates the effect of injecting or discharging water into the float 1, thereby controlling the buoyancy of the float 1. Rotating the worm gear 8 through the handle 9 drives the threaded sleeve 6 to rotate via the worm wheel 7, which in turn drives the threaded rod 3 to rise or fall under the guidance of the guide sleeve 2, thus controlling the depth at which the sand measuring instrument 5, installed in the protective frame 4, sinks into the water, adapting to sediment flow monitoring at different water depths. The sand measuring instrument 5 is floated on the float 1, ensuring that the float 1 remains afloat during water level rises and falls. The sand measuring instrument 5 remains submerged in the water, directly accompanying the float 1. When the float 1 is floating, the vertical rod 11, in conjunction with the sliding sleeve 10, guides the float 1's movement, effectively preventing it from drifting away from the monitoring area.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
