Description

Technical Field

[0001] The present invention relates to the technical field of hydrological monitoring, and in particular to a hydrological information monitoring device. Background Art

[0002] When monitoring hydrological information of rivers and other watersheds, the monitoring content generally includes river depth, river area, water level, flow, flow velocity, sediment, water quality, pollutants, etc., and the existing technology has been adapted to a variety of dedicated sensor monitoring devices.

[0003] When monitoring sediment, it is necessary to detect data on changes in sediment accumulation thickness and sediment type information (which can be used to study water flow and sediment flow information in nearby waters). However, existing monitoring devices are not well adapted to sediment information monitoring and are mainly based on water velocity and water level monitoring. They cannot retain information on the flow changes of sediment at the bottom of the river, which is not conducive to hydrological information monitoring and research, and is not convenient for grasping the laws of changes in nearby waters.

[0004] In the prior art, the problem of not being able to well retain the flow change information of the sediment at the bottom of the river needs to be solved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a hydrological information monitoring device in view of the above-mentioned technical deficiencies, which solves the problem in the prior art that the flow change information of the sediment at the bottom of the river channel cannot be well retained.

[0006] The technical solution adopted by the present invention is to provide a hydrological information monitoring device, comprising:

[0007] The positioning pipe has a pre-buried pipe at the bottom, a vertical window arranged vertically on the middle side wall, and a top plate at the upper end. The pre-buried pipe is used to be inserted into the bottom of the river channel, and the vertical window part is located above the sediment at the bottom of the river channel; the top plate is located above the water surface of the river channel;

[0008] A lifting tube, which is lifted and lowered in the positioning tube, and a side wall of the lifting tube has a through hole, and the through hole is used to communicate with the vertical window;

[0009] There are a plurality of sand storage tanks, which are arranged in series in a vertical direction, and the upper part of the side wall of the sand storage tank is provided with a sand inlet, which is used to connect with the through hole;

[0010] A sounding plate is slidably sleeved on the outside of the positioning tube, the lifting tube is used to drive the sounding plate to rise, and the sounding plate is separated from the lifting tube and descends by gravity to abut against the upper end of the sediment at the bottom of the river channel;

[0011] The distance measuring device is arranged on the top plate and is used to detect the depth of the depth measuring plate below.

[0012] To further optimize this technical solution, it further includes:

[0013] A sleeve, slidably sleeved on the positioning tube;

[0014] A tapered tube, sleeved around the positioning tube. The lower end diameter of the tapered tube is larger than the upper end diameter. The upper end of the tapered tube is arranged at the lower end of the sleeve, and the lower end of the tapered tube is arranged on the sounding plate. There is a gap between the inner ring surface of the sounding plate and the outer surface of the positioning tube.

[0015] To further optimize this technical solution, the lifting tube acts on the sleeve to drive the sounding plate to rise. The lifting tube is rotatably arranged relative to the sleeve; there are a plurality of horizontally arranged slots and a vertically arranged communication slot on the side wall of the lifting tube. The plurality of slots are vertically spaced in an array, and the communication slot communicates with one side of the slot; it further includes:

[0016] A guide rod, arranged on the inner wall of the sleeve. One end of the guide rod slides in the slot or rises and falls in the communication slot. When one end of the guide rod is in the slot, the lifting tube drives the sounding plate to rise.

[0017] To further optimize this technical solution, the side surface of the tapered tube has an avoidance window, and the avoidance window is opposite to the position of the vertical window.

[0018] To further optimize this technical solution, it further includes:

[0019] A sand blocking ring, sleeved on the inner wall of the lifting tube. The outer wall of the sand storage tank is in sliding contact with the inner wall of the sand blocking ring. The sand blocking ring is used to block the sand inlet.

[0020] To further optimize this technical solution, the upper end of the lifting tube has a transmission platform, and the lower end of the transmission platform has an annular lifting rail; it further includes:

[0021] A slider, slidably arranged on the lifting rail;

[0022] A linear driving mechanism, arranged on the top plate. The moving end of the linear driving mechanism is arranged on the slider and is used to drive the lifting tube to rise and fall.

[0023] To further optimize this technical solution, there are a plurality of vertically arranged reinforcing plates around the embedded tube.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. After the lifting pipe drives the sounding plate to rise, the sounding plate detaches from the lifting pipe and naturally falls under its own weight, pressing on the upper end of the sediment. The sounding plate serves as a detection marker, and the ranging device can measure the depth change of the sounding plate, thereby calculating the change in the accumulation thickness of the sediment.

[0026] 2. The sediment storage tank can store the sediment at the bottom of the river channel. Several sediment storage tanks can store sediment at different time intervals, retaining sediment from different times, so as to retain information on sediment flow changes, and infer the sediment flow changes in the nearby water area based on the types and characteristics of the sediment.

[0027] 3. When the lifting pipe moves up and down, the height position of the vertical window can also be adjusted to adapt to the change in the sediment thickness. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0039] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, for the components with the same structure or function, only one of them is schematically shown, or only one of them is labeled. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0040] In this article, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0041] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0042] Such as Figures 1-9As shown in the figure, a hydrological information monitoring device includes: a positioning pipe 1, which has a buried pipe 101 at the lower part, a vertical window 102 vertically arranged on the middle side wall, and a top plate 103 at the upper end. The buried pipe 101 is used to be inserted into the inside of the river bottom. The vertical window 102 is partially above the sediment at the river bottom. The top plate 103 is above the river water surface; a lifting pipe 2, which is lifted and arranged in the positioning pipe 1. The side wall of the lifting pipe 2 has a through hole 201, and the through hole 201 is used to communicate with the vertical window 102; a sand storage tank 3, which has several. The several sand storage tanks 3 are arranged in sequence along the vertical direction. The upper part of the side wall of the sand storage tank 3 has a sand inlet 301, and the sand inlet 301 is used to be connected and communicated with the through hole 201; a sounding plate 4, which is slidably sleeved outside the positioning pipe 1. The lifting pipe 2 is used to drive the sounding plate 4 to rise. After the sounding plate 4 is separated from the lifting pipe 2 and drops by gravity, it is used to abut against the upper end of the sediment at the river bottom; a ranging device 5, which is arranged on the top plate 103 and is used to detect the depth of the sounding plate 4 below.

[0043] When in use, the positioning pipe 1 is vertically arranged. The buried pipe 101 at the lower part is buried into a relatively firm depth at the river bottom to fix the positioning pipe 1. At the same time, other auxiliary positioning devices can be added to enhance stability. Part of the vertical window 102 is exposed above the sediment at the river bottom and part is below the sediment, which is convenient for adapting to the change of sediment thickness. Generally, the sediment gradually increases, so the exposed part of the vertical window 102 can be more. The vertical window 102 has a long distance in the vertical direction to leave space for the lifting of the sounding plate 4. The sounding plate 4 is a measurement marker for monitoring the change of sediment depth, which is convenient for accurate ranging. When the sounding plate 4 lands on the upper end of the sediment, the depth of the sounding plate 4 can be measured by the ranging device 5. The lifting pipe 2 carries the sounding plate 4 to move upward, so that the sounding plate 4 is lifted a certain height away from the upper surface of the sediment and can stay for a period of time to wait for the sediment below the sounding plate 4 to level. Then the sounding plate 4 is separated from the carrying of the lifting pipe 2 and lands on the upper surface of the sediment relatively slowly under the action of gravity and water resistance, re-calibrating the depth of the sediment, and then the depth or thickness change of the sediment can be calculated.

[0044] The through hole 201 of the lifting pipe 2 is communicated with the vertical window 102, and the height is near the sediment surface layer. The sand inlet 301 of one of the sand storage tanks 3 is communicated with the through hole 201. Then the upper surface sediment can enter the sand storage tank 3 through the vertical window 102, the through hole 201 and the sand inlet 301 in sequence and be retained as a sample. After a sampling and retention period, the sand storage tank 3 moves upward, and the next sand storage tank 3 receives a new sediment sample. The depth position of the through hole 201 and the position of the sand inlet 301 of the sand storage tank 3 can be used to know the sediment surface depth obtained by the sounding plate 4, and then control the depth of the lifting pipe 2 and the sand storage tank 3 to extract sediment samples near the required depth. Initially, several sand storage tanks 3 are located below the vertical window 102, that is, inside the buried pipe 101, and gradually move upward to achieve sequential sampling and retention.

[0045] The lifting of the sand storage tank 3 can be driven and controlled by means of existing lifting mechanisms, and the depth can be controlled by means of existing measurement and control technologies. For example, the sand storage tank 3 can be driven to rise by a winch structure, or driven by an existing rack and pinion structure. These are all existing technologies, and those skilled in the art can select appropriate driving means, which will not be shown in this application. Similarly, the lifting of the lifting pipe 2 can also adopt existing conventional technical means, and a hydraulic driving mechanism can be used as the linear driving mechanism 9 to drive the lifting of the lifting pipe 2. When the lifting pipe 2 is lifted or lowered, the sand storage tank 3 can follow. It can be manually controlled or automatically operated after being combined with an automatic control system.

[0046] The ranging device 5 can be an existing electronic scanning ranging device. Corresponding markers are made on the sounding board 4 for accurate measurement, or it can be a ranging ruler, such as a tape measure, etc. One end acts on the sounding board 4 and the other end is located on the top plate 103. The top plate 103 can be a reference plane. By straightening the tape measure, the value can be read, and the depth change of the sounding board 4 can be obtained through manual calculation.

[0047] Furthermore, it further includes: a sleeve 401, which is slidably sleeved on the positioning pipe 1; a tapered pipe 402, which is sleeved on the periphery of the positioning pipe 1. The lower diameter of the tapered pipe 402 is larger than the upper diameter. The upper end of the tapered pipe 402 is arranged at the lower end of the sleeve 401, and the lower end of the tapered pipe 402 is arranged on the sounding board 4. There is a gap between the inner ring surface of the sounding board 4 and the outer surface of the positioning pipe 1. The side surface of the tapered pipe 402 has an avoidance window 4021, and the avoidance window 4021 is opposite to the vertical window 102 in position.

[0048] During use, the sounding board 4 is connected to the sleeve 401 through the tapered pipe 402 and slides up and down on the positioning pipe 1. The tapered pipe 402 is smaller at the top and larger at the bottom. The sounding board 4 is annular and there is an annular spaced space between the inner ring surface and the outer surface of the positioning pipe 1, which can avoid the space near the periphery of the positioning pipe 1. The obstruction of the sediment outside the positioning pipe 1 can cause a bulge to form nearby, which cannot truly reflect the actual height of the sediment.

[0049] During use, the avoidance window 4021 on the tapered pipe 402 can provide a channel for the flow of sediment, facilitating the entry of sediment into the sand storage tank 3.

[0050] Furthermore, the lifting pipe 2 acts on the sleeve 401 to drive the sounding board 4 to rise. The lifting pipe 2 is rotatably arranged relative to the sleeve 401; there are a number of horizontally arranged slots 202 and a vertically arranged communication slot 203 on the side wall of the lifting pipe 2. The number of slots 202 is arranged in a vertical interval array, and the communication slot 203 is communicated with one side of the slot 202; it further includes: a guide rod 6, which is arranged on the inner wall of the sleeve 401. One end of the guide rod 6 slides in the slot 202 or rises and falls in the communication slot 203. When one end of the guide rod 6 is in the slot 202, the lifting pipe 2 drives the sounding board 4 to rise.

[0051] During use, the sounding board 4 can be connected to the lifting pipe 2 through the sleeve 401 and rise together. After being disconnected, the sounding board 4 freely descends. The detachable connection between the sleeve 401 and the lifting pipe 2 can be realized through existing structures such as electric plug structures and magnetic attraction. It can also be realized by the cooperation of the guide rod 6 and the slot 202 and the communication slot 203, without the need to set up electric control components underwater. A horizontal guide rod 6 is arranged on the inner wall of the sleeve 401, and a slot 202 is arranged on the side wall of the lifting pipe 2 opposite to the position of the vertical window 102. A plurality of slots 202 are arranged at intervals in the vertical direction, and one side of the slot 202 is communicated through a vertical communication slot 203. The slot 202 is located above the through hole 201. When the guide rod 6 is in the slot 202, the sleeve 401 can rise or fall following the lifting pipe 2. The lifting pipe 2 rotates and is arranged vertically and movably in the positioning pipe 1. When the lifting pipe 2 rotates relative to the sleeve 401, the guide rod 6 slides into the communication slot 203 from the slot 202. In the communication slot 203, the sleeve 401 and the sounding board 4 can freely descend.

[0052] When the lifting pipe 2 rotates, the sand storage tank 3 inside can rotate accordingly. And through the setting of the length of the slot 202, when the communication slot 203 moves to the position of the guide rod 6, the through hole 201 and the sand inlet 301 turn to the inner wall of the lifting pipe 2 and are not communicated with the vertical window 102. At this time, the rise of the water flow caused by the rise of the sounding board 4 can be reduced to bring out the samples retained in the sand storage tank 3, and the influence is relatively small when the sounding board 4 descends and can be ignored.

[0053] The vertical window 102 on the positioning pipe 1 can be arranged to penetrate along the diameter direction, so there are two opposite vertical windows 102. At the same time, two groups of slots 202 and communication slots 203 can be arranged relatively on the lifting pipe 2, and multiple guide rods 6 are correspondingly arranged on the sleeve 401, making the lifting more stable.

[0054] Furthermore, it further includes: a sand blocking ring 7, sleeved on the inner wall of the lifting pipe 2, the outer wall of the sand storage tank 3 is in sliding contact with the inner wall of the sand blocking ring 7, and the sand blocking ring 7 is used to block the sand inlet 301.

[0055] During use, the sand blocking ring 7 can be arranged along the inner wall of the lifting pipe 2 while avoiding the through hole 201. The sand blocking ring 7 can be made of elastic material or flexible material, as long as it can block the sand inlet 301, and sealing is not required.

[0056] Furthermore, the upper end of the lifting pipe 2 has a transmission platform 8, and the lower end of the transmission platform 8 has an annular lifting rail 801; it further includes: a slider 802, slidably arranged on the lifting rail 801; a linear driving mechanism 9, arranged on the top plate 103, and the moving end of the linear driving mechanism 9 is arranged on the slider 802 for driving the lifting pipe 2 to rise and fall.

[0057] In use, the lifting pipe 2 rotates and is arranged for lifting inside the positioning pipe 1. The lifting pipe 2 can be driven to lift or lower by a linear driving structure such as a hydraulic component. The moving end of the linear driving mechanism 9 is slidably connected to the transmission platform 8 through a slider 802. When the transmission platform 8 rotates following the lifting pipe 2, it does not affect the operation of the linear driving mechanism 9. The rotation of the lifting pipe 2 can be driven by a motor and a gear structure. The motor can be arranged on the top plate 103, and the gear is sleeved on the lifting pipe 2. The gear transmission structure allows axial relative movement within a certain range, that is, the axial length of the gear sleeved on the lifting pipe 2 is relatively long. When the lifting pipe 2 lifts or lowers, the gear transmission can still be maintained. Or the motor can also follow the lifting pipe 2 to lift or lower on the top plate 103. These are all conventional technical means and can be achieved by those skilled in the art.

[0058] Furthermore, several vertically arranged reinforcing plates 1011 are provided on the periphery of the embedded pipe 101.

[0059] In use, the embedded pipe 101 extends deep into the ground at the bottom of the river. The fixing stability can be improved through the reinforcing plates 1011. The positioning pipe 1 can also be fixed stably by means of diagonal bracing. The embedded pipe 101 also leaves space for the downward movement of the lifting pipe 2 and the sand storage tank 3. In the drawings, the length of the embedded pipe 101 does not represent the actual length or scale, and an appropriate length can be set according to different river bottom environments to achieve greater stability.

[0060] It can be understood that the present invention is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present invention, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
