Description

Technical Field

[0001] The utility model belongs to the technical field of suspended sediment water sample processing, in particular to a suspended sediment water sample drainage device. Background Art

[0002] Suspended sediment testing is a key component of hydrological surveys, primarily measuring suspended sediment transport rate, sediment content, and particle size distribution in rivers. After suspended sediment sampling, samples must undergo sedimentation. According to the "Specifications for Suspended Sediment Testing in Rivers," sedimentation time must be no less than 24 hours to ensure sufficient sedimentation. After sedimentation, suspended sediment settles to the bottom of the sediment bucket, and the upper layer of clear water is discharged through a siphon. This process ensures that no sediment is aspirated from the bottom. However, in practice, using an ear bulb to siphon the upper layer of clear water requires manual operation. This requires focused attention, closely monitoring the water level inside the bucket and the flow of water outside. Furthermore, multiple operations, such as moving the drainpipe up and down, and securing it left and right, are required. This is not only time-consuming and labor-intensive, but can also easily cause disturbances that can lift sediment from the bottom, leading to failure. Especially during flood seasons, when sediment transport rate testing is frequent and requires handling a large number of suspended sediment samples, traditional siphoning methods significantly increase the workload and difficulty for test personnel.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] The utility model is a specific embodiment of a suspended sediment water sample drainage device, as shown in FIG. Figure 1-4 As shown;

[0027] A suspended sediment water sample drainage device includes a drainage pipe and a fixing fixture; the drainage pipe includes an inlet pipe 21, a connecting pipe 22 and an outlet pipe 24, and the inlet pipe 21, the connecting pipe 22 and the outlet pipe 24 are movably connected in sequence, the connecting pipe 22 is located on the fixing fixture, and the outlet pipe 24 is also provided with a siphon device; the fixing fixture includes a connecting pipe fixing groove and a position fixing clamp 16; the connecting pipe 22 is located in the connecting pipe fixing groove, and a gear 15 is installed on the connecting pipe fixing groove. A rack 221 is provided on the upper side of the connecting pipe 22, and the rack 221 is engaged with the gear 15. By rotating the gear 15, the connecting pipe 22 is moved, thereby adjusting the water inlet depth of the water inlet pipe 21.

[0028] When in use, fix the position fixing clamp 16 on the wall of the sediment bucket A containing the suspended sediment water sample after precipitation, extend the inlet end of the water inlet pipe 21 into the clear water layer after the suspended sediment water sample is precipitated, and place the outlet end of the water outlet pipe 24 in the empty water tank B. Start the siphon device to start draining. The liquid level of the clear water layer drops, and slowly rotate the gear 15 to keep the inlet end of the water inlet pipe 21 in the clear water layer, avoiding the traditional drainage pipe from being extended too quickly.

[0029] The problem of disturbing the sediment and causing it to be discharged with the water.

[0030] This solution drains water through a siphon device, and a position fixing clamp 16 is set so that the drainage pipe can be conveniently fixed on the wall of the mud bucket A. By setting a connecting pipe 22 and a gear 15 that match the gear 15, the gear 15 is rotated to slowly adjust the water inlet depth of the water inlet pipe 21, which makes operation more convenient and the depth of the water inlet pipe 21 easier to control.

[0031] As a further setting of the present invention, the position fixing clip 16 is a U-shaped clip with an opening facing downward. One side of the U-shaped clip is straight, and the other side is arc-shaped and bent outward. The convex point of the arc is tightly attached to the straight side, and the opening of the fixing clip has a gap. When in use, the straight side is located on the inner wall of the mud and sand bucket A.

[0032] Since the number of suspended water samples is large and multiple drainage is required, a U-shaped position fixing clamp 16 is provided to facilitate switching and fixing of multiple sediment buckets A.

[0033] As a further setting of the present invention, the position fixing clamp 16 is fixed to the lower part of the connecting pipe fixing groove, and the connecting pipe fixing groove includes three sections, namely a line-segment-shaped water inlet fixing groove 11, an arc-shaped fixing groove 12 and a line-segment-shaped water outlet fixing groove 13. The water inlet fixing groove 11 is inclined downward, and the inlet end of the water inlet fixing groove 11 is inclined toward the direction close to the position fixing clamp 16. The water outlet fixing groove 13 is inclined downward, and the outlet end of the water outlet fixing groove 13 is inclined toward the direction away from the position fixing clamp 16. The arc-shaped fixing groove 12 connects the upper ends of the water inlet fixing groove 11 and the water outlet fixing groove 13 in sequence.

[0034] By setting a three-section connecting pipe fixing groove, the linear water outlet fixing groove 13 can prevent the teeth of the upper rack 221 of the connecting pipe 22 from being bent and squeezed, thereby facilitating the engagement of the rack 221 with the gear 15; the water inlet fixing groove 11 is inclined toward the position fixing clamp 16, so that the water inlet part of the water inlet pipe 21 can be attached to the inner wall of the sediment bucket A, which is not easy to shake, thereby avoiding the disturbance of the sediment caused by shaking; the arc-shaped fixing groove 12 can reduce the bending amplitude of the connecting pipe 22, thereby facilitating the movement and drainage of the connecting pipe 22.

[0035] As a further feature of the present invention, the bottom of the connecting pipe fixing groove is an upwardly directed arcuate groove, and arcuate fixing pieces 14 are provided at least at the two ends of the connecting pipe fixing groove and on both sides of the curved portion. The bottom of the arcuate fixing pieces 14 is fixedly engaged with the arcuate groove, and the distance between the corresponding arcuate fixing pieces 14 is greater than the width of the rack 221. The rack 221 is positioned between the corresponding arcuate fixing pieces 14, allowing the connecting pipe 22 to move within the connecting pipe fixing groove. If the water inlet fixing groove 11, the arcuate fixing groove 12, or the water outlet fixing groove 13 is too long, more arcuate fixing pieces 14 should be provided to strengthen the fixation of the multiple connecting pipes 22.

[0036] This arrangement facilitates the fixing and removal of the connecting tube 22 .

[0037] As a further configuration of the present invention, the gear 15 is located on the water outlet fixed groove 13; two triangular fixing frames 151 are provided at the same position on both sides of the water outlet fixed groove 13, and the bottom sides of the triangular fixing frames 151 are fixedly overlapped with the two sides of the water outlet fixed groove 13, and a threaded hole is provided on the top of the triangular fixing frame 151, through which a bolt passes through the threaded hole and the gear 15, and the gear 15 is fixed to the triangular fixing frame 151 in conjunction with a nut.

[0038] The triangular fixing frame 151 makes the gear 15 more stable relative to the water outlet fixing groove 13. By rotating the gear 15, the water inlet depth of the water inlet pipe 21 is slowly adjusted, which is more convenient to operate and accurately control, and reduces sediment disturbance.

[0039] As a further configuration of the present invention, the top of the position fixing clamp 16 is fixedly connected to the end of the water inlet fixing groove 11 and the bottom of the water outlet fixing groove 13 where the gear 15 is located.

[0040] Since the gear 15 is the main part for manual operation and the main force point, the top of the position fixing clip 16 is fixedly connected to the bottom of the water outlet fixed groove 13 where the gear 15 is located, which is not easy to be damaged and increases the service life; and the end of the water inlet fixed groove 11 is fixedly connected to the position fixing clip 16, which can reduce the deformation of the water inlet fixed groove 11 and prevent the tilt direction from changing.

[0041] As a further setting of the present invention, the siphon device includes a siphon ball 231 and a Y-shaped tee 232. The two upper ends of the Y-shaped tee 232 are respectively connected to the water outlet end of the connecting pipe 22 and the siphon ball 231, and the lower end of the Y-shaped tee 232 is connected to the water inlet end of the outlet pipe 24.

[0042] By providing the siphon ball 231 , when the pressure difference is insufficient, the air can be exhausted and the pressure can be reduced in time to prevent drainage interruption; by providing the Y-shaped tee 232 , the discharged water can be prevented from flowing into the siphon ball 231 .

[0043] As a further configuration of the present invention, a one-way outward exhaust valve 2311 is provided on the siphon ball 231 , and a one-way water stop valve 233 for one-way water discharge to the outlet pipe 24 is provided at the lower end of the Y-shaped tee 232 .

[0044] By providing a one-way exhaust valve 2311, a pressure difference can be quickly formed; by providing a one-way water stop valve 233, water backflow can be prevented.

[0045] As a further configuration of the present invention, a small hole is provided on the side wall of the water inlet end of the water inlet pipe 21 .

[0046] By setting small holes, at the end of drainage, the siphon pressure in the water pipe is slowly released through the small holes, effectively avoiding the situation where the siphon pressure in the water pipe is suddenly released and causes sediment sedimentation disturbance.

[0047] It should be noted that the water inlet pipe, connecting pipe and outlet pipe are all conventional hoses; the rack is bendable and can be made of cow tendon; the rack can be glued to the connecting pipe; and the siphon ball is made of an extrudable material.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
