Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a hydrological sediment content testing device. Background Technology

[0002] Water conservancy refers to the development of water resources and the prevention of floods. In practical water conservancy projects, the detection of sediment content in water is an essential testing item. This requires a high-efficiency water conservancy sediment content detection device to assist in the detection. Sediment content is generally the mass of dry sand contained in a unit volume of turbid water. When detecting sediment content, water and sand need to be separated into solid and liquid components. After separation, the sand is dried to determine the sediment content. However, solid-liquid separation is not precise enough, has low efficiency, and is time-consuming.

[0003] Chinese patent document CN221124186U discloses a hydrological sediment content detection device. The device features a groove on the top of the inner wall of the detection chamber, with a drying component fixedly connected inside the groove. The extrusion component includes an A motor housing, inside which an A servo motor is fixedly installed. The output end of the A servo motor is splinedly connected to an A transmission rod. Through the extrusion and filtration components, sediment is placed on the filtration component. The filtration component is then activated to perform solid-liquid separation of the sediment. During this separation process, the extrusion component is activated to repeatedly squeeze the sediment, removing excess water and accelerating the filtration speed.

[0004] The existing technology has the following problems:

[0005] First, the aforementioned device squeezes water out of the silt placed in a filter screen, and after drying, the silt is difficult to remove, making the process cumbersome. Second, when the silt is squeezed out of the device, the mud and water directly pass over the surface of the threaded rods, which, over time, will affect the normal operation of the threads.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-6 As shown, a water conservancy and hydrology sediment content detection device includes a box 1, a draining and pouring assembly 2 is movably connected to the middle of the inner wall of the box 1, and an adjusting and squeezing assembly 3 is movably connected to the top of the inner wall of the box 1.

[0030] The draining and pouring assembly 2 includes a rotating shaft 21. The front and rear ends of the rotating shaft 21 are rotatably connected to the middle of the right side of the inner wall of the box 1. A support frame 22 is fixedly sleeved on the middle of the outer wall of the rotating shaft 21. A filter screen 23 is fixedly connected to the middle of the inner wall of the support frame 22. A baffle frame 24 is fixedly installed at the upper edge of the support frame 22 outside the filter screen 23. An extension plate 25 is fixedly connected to the left side of the support frame 22. A discharge chute 26 with a matching extension plate 25 is opened through the middle of the left side of the box 1. A dryer 27 located above the baffle frame 24 is fixedly installed at the top of the right side of the inner wall of the box 1.

[0031] The adjusting extrusion assembly 3 includes two guide pillars 31. The left and right ends of the two guide pillars 31 are fixedly installed at the front and rear positions of the top of the inner wall of the box 1. The left and right sides of the outer side of the two guide pillars 31 are slidably connected to the moving plates 32. The lower middle of the two moving plates 32 is fixedly installed with a rectangular frame 33 with an open bottom. The front and rear sides of the inner wall of the two rectangular frames 33 are fixedly installed with slide rails 34. The inner walls of four adjacent slide rails 34 are slidably connected with moving frames 35 with an open top. The lower ends of the two moving frames 35 are fixedly installed with extrusion plates 36 located in the inner cavity of the baffle frame 24. The rear top of the box 1 is provided with a feed hopper 37. One end of the feed hopper 37 extending into the inside of the box 1 is located between the two extrusion plates 36.

[0032] The draining and pouring assembly 2 separates water and sand into solid and liquid components. After the sand dries, it can be discharged from the discharge chute 26 using the rotating support frame 22, facilitating subsequent weighing by workers. The squeezing assembly 3 can be adjusted to squeeze water out of the sand at the top of the filter screen 23. Combined with the draining and pouring assembly 2, it enables both convenient water discharge and adjustable material discharge. Furthermore, the drive structure for adjusting the two moving plates 32 is located at the top of the housing 1, unaffected by mud and sand, making it highly practical.

[0033] like Figure 3 and Figure 4 As shown, the front part of the outer wall of the rotating shaft 21 passes through the front part of the housing 1 and is fixedly sleeved with a worm gear 28. A worm 29 is rotatably connected to the middle part of the front right side of the housing 1. A motor 210 is fixedly installed on the front right side of the housing 1 to the left of the worm 29. The output end of the motor 210 is fixedly connected to the left end of the worm 29. The outer wall of the worm 29 meshes with the outer surface of the worm gear 28.

[0034] The output end of motor 210 can drive worm 29 to rotate. Worm wheel 28 drives shaft 21 to rotate by meshing with worm 29. Shaft 21 drives support frame 22, filter screen 23 and extension plate 25 to flip, so that filter screen 23 is in an inclined state, so that dried sand can be discharged from discharge chute 26.

[0035] like Figure 4 As shown, a pressure sensor is fixedly installed inside the extension plate 25.

[0036] The pressure sensor plays an auxiliary role, detecting the weight of the passing sand to a certain extent, which helps workers weigh and pour out the sand later. When the extension plate 25 is in a horizontal state, its upper end overlaps with the top of the inner wall of the discharge chute 26.

[0037] like Figure 3 and Figure 4 As shown, a telescopic rod 211 is rotatably connected to the lower left side of the extension plate 25, and the bottom of the telescopic rod 211 is rotatably connected to the bottom left side of the box 1.

[0038] The telescopic rod 211 provides guidance and support for the rotation of the extension plate 25.

[0039] like Figure 4 As shown, a bidirectional lead screw 38 is rotatably connected to the top of the inner wall of the housing 1 between two guide posts 31, passing through the left side of the housing 1. A second motor 39 is fixedly installed on the top left side of the housing 1. The output end of the second motor 39 is fixedly connected to the left end of the bidirectional lead screw 38. The inner walls of the middle part of the two moving plates 32 are threadedly connected to the left and right parts of the outer wall of the bidirectional lead screw 38.

[0040] The output end of motor 39 can drive the bidirectional lead screw 38 to rotate. The two moving plates 32 move relative to each other through threaded connection with the bidirectional lead screw 38, so that the pressing plates 36 at the bottom of the two moving frames 35 can approach each other and press the mud and sand between them.

[0041] like Figure 5 and Figure 6 As shown, a hydraulic rod 310 is fixedly installed on the top of the inner wall of the right rectangular frame 33, and the output end of the hydraulic rod 310 is fixedly connected to the bottom of the inner wall of the right movable frame 35.

[0042] The output end of the hydraulic rod 310 can drive the right movable frame 35 to rise and fall in the right rectangular frame 33. The right movable frame 35 drives the left movable frame 35 to rise and fall through the receiving sleeve 311, connecting rod 312 and slider 313, so that the two extrusion plates 36 can rise and fall through the two movable frames 35, which can avoid affecting the discharge of dry sand.

[0043] like Figure 6 As shown, a Z-shaped receiving sleeve 311 is fixedly installed on the bottom left side of the right movable frame 35, and a Z-shaped connecting rod 312 is fixedly installed on the bottom right side of the left movable frame 35. A slider 313 is fixedly installed on the right end of the connecting rod 312, and the outer wall of the slider 313 is slidably connected to the inner wall of the receiving sleeve 311.

[0044] When the two movable plates 32 move relative to each other, the connecting rod 312 moves in the receiving sleeve 311 through the slider 313. When the hydraulic rod 310 is activated, the connecting rod 312 and the slider 313 can connect to each other, which facilitates the synchronous movement of the two movable frames 35.

[0045] like Figure 3 As shown, trapezoidal guide seats 4 are fixedly installed on the left and right sides of the bottom of the inner wall of the box 1. Several water outlet pipes 5 are fixedly installed through the middle of the lower end of the box 1 and are arranged linearly between two guide seats 4. Valves are fixedly installed at the bottom of the inner cavity of the several water outlet pipes 5.

[0046] After the solid-liquid separation of mud and sand, the mud and water are concentrated at the top of several outlet pipes 5 because of the two guide seats 4. When draining water later, the valve connected to the outlet pipe 5 can be opened.

[0047] The working principle of this utility model is as follows: During use, a measured amount of mud and sand is poured into the housing 1 from the feed hopper 37. At this time, the mud and sand are located on the filter screen 23 and between the two extrusion plates 36. The filter screen 23 separates the solid and liquid components of the mud and sand. The sand is located at the upper end of the filter screen 23, while the muddy water is concentrated at the top of several outlet pipes 5 due to the two guide seats 4. The motor 39 starts, and its output can drive the bidirectional lead screw 38 to rotate. The two moving plates 32 move relative to each other through a threaded connection with the bidirectional lead screw 38, thereby allowing the extrusion plates 36 at the bottom of the two moving frames 35 to approach each other and extrude the mud and sand between them, further squeezing out the water in the sand. The dryer 27 is an existing structure that dries the sand, reducing residual moisture. When the moisture content of the sediment is tested later, the dry sand needs to be discharged. The hydraulic rod 310 is started, and its output end can drive the right moving frame 35 to rise and fall in the right rectangular frame 33. The right moving frame 35 drives the left moving frame 35 to rise and fall through the receiving sleeve 311, connecting rod 312 and slider 313, so that the two extrusion plates 36 can rise and fall through the two moving frames 35, which can avoid affecting the discharge of dry sand.

[0048] Then, motor 210 is started, and its output can drive the worm gear 29 to rotate. The worm wheel 28, through meshing with the worm gear 29, drives the rotating shaft 21 to rotate. The rotating shaft 21 causes the support frame 22, filter screen 23, and extension plate 25 to flip, so that the filter screen 23 is in an inclined state, which facilitates the discharge of dried sand from the discharge chute 26. The pressure sensor plays an auxiliary role, which can detect the weight of the sand passing through to a certain extent, which helps the workers to weigh and pour out the sand later.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
