Description

Technical Field

[0001] This utility model relates to the field of hydrological monitoring technology, and in particular to a hydrological information acquisition device. Background Technology

[0002] Hydrological data collection, also known as hydrological surveying, refers to the general term for the technical work of systematically collecting and processing hydrological data. In a narrower sense, hydrological data collection refers to the observation of hydrological elements, and it is the foundation of hydrology. Currently, when collecting water samples in the field, it is usually necessary to collect multiple samples at different depths from the same location. However, current sampling devices often cannot collect samples from multiple depths simultaneously, only from one depth at a time. This results in time-consuming operations, and during the insertion and extraction of the sample, water from other depths can easily mix into the sample, affecting the accuracy of the data collection. Improvements are needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hydrological information acquisition device that can collect water samples from multiple depths at the same time, and can avoid the mixing of water samples from different depths, thereby improving the sampling accuracy.

[0004] The technical solution adopted by this utility model is as follows: a hydrological information collection device is provided, including a vertically arranged installation cylinder; an adjusting rod is slidably sleeved inside the installation cylinder; a telescopic device is provided inside the installation cylinder; the fixed end of the telescopic device is connected to the upper end of the installation cylinder, and the telescopic end of the telescopic device is vertically downward and connected to the upper end of the adjusting rod; a through groove is opened vertically on the outer wall of the installation cylinder; and multiple water collection components are provided on the installation cylinder.

[0005] The water intake assembly includes a water intake box and a pressure cap correspondingly disposed above the water intake box; a first connecting sleeve is fixed to the outside of the water intake box; a second connecting sleeve is fixed to the outside of the pressure cap; both the first and second connecting sleeves are slidably fitted onto the outside of the mounting cylinder; a first set screw is screwed onto the first connecting sleeve; a second set screw is screwed onto the second connecting sleeve; the first set screw abuts and locks against the outer wall of the mounting cylinder; the second set screw passes through the through groove and abuts and locks against the outer wall of the adjusting rod.

[0006] To further optimize this technical solution, an open opening is provided at the lower end of the mounting cylinder of the hydrological information acquisition device.

[0007] To further optimize this technical solution, the outer wall of the mounting cylinder of the hydrological information acquisition device is equipped with height markings.

[0008] To further optimize this technical solution, the pressure cap of the hydrological information acquisition device is vertically connected with an insertion post; the water intake box is fixed with a guide sleeve; the insertion post and the guide sleeve are inserted and matched accordingly.

[0009] The beneficial effects of this utility model are as follows:

[0010] By sliding the first ring on the mounting cylinder, the relative height of each water sampling box can be changed. The mounting cylinder is then inserted into the water to a specified depth, allowing for simultaneous collection of water samples from multiple depths using multiple sampling boxes. The sampling boxes can be individually sealed with caps to protect the water samples.

[0011] The second set screw passes through the through groove and abuts against the outer wall of the adjusting rod to lock it in place, thus fixing the second connecting sleeve to the adjusting rod. By controlling the adjusting rod to move up and down inside the mounting cylinder through the telescopic device, the second connecting sleeve can be moved accordingly, thereby controlling the sealing and separation of the pressure cap and the water collection box. This prevents water samples from different depths before and after water collection from mixing into the water collection box, improving sampling accuracy. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, the hydrological information acquisition device includes a vertically arranged installation cylinder 1; an adjusting rod 2 is slidably sleeved inside the installation cylinder 1; an expansion joint 3 is provided inside the installation cylinder 1; the fixed end of the expansion joint 3 is connected to the upper end of the installation cylinder 1, and the telescopic end of the expansion joint 3 is vertically downward and connected to the upper end of the adjusting rod 2; a through groove 4 is opened vertically on the outer wall of the installation cylinder 1; and multiple water intake components are provided on the installation cylinder 1.

[0018] like Figure 1-3As shown, the water intake assembly includes a water intake box 5 and a pressure cap 6 correspondingly disposed above the water intake box 5; a first connecting sleeve 7 is fixed to the outside of the water intake box 5; a second connecting sleeve 8 is fixed to the outside of the pressure cap 6; both the first connecting sleeve 7 and the second connecting sleeve 8 are slidably sleeved on the outside of the mounting cylinder 1; a first set screw 9 is screwed onto the first connecting sleeve 7; a second set screw 10 is screwed onto the second connecting sleeve 8; the first set screw 9 abuts and locks against the outer wall of the mounting cylinder 1; the second set screw 10 passes through the through groove 4 and abuts and locks against the outer wall of the adjusting rod 2.

[0019] First, based on the need to collect water samples at various depths, install the corresponding number of water collection components on the installation cylinder 1. Then, by sliding the first connecting sleeve 7 and the second connecting sleeve 8, adjust the water collection box 5 and the pressure cap 6 to the appropriate height positions on the installation cylinder 1 (the height can be measured with an external measuring ruler). With the pressure cap 6 sealing the water collection box 5, tighten the first set screw 9 and the second set screw 10 respectively to lock the first connecting sleeve 7 and the second connecting sleeve 8.

[0020] Next, the installation cylinder 1 is inserted into the water. Before reaching the designated depth, the pressure cap 6 keeps the water collection box 5 sealed, preventing water samples from entering prematurely. After reaching the designated depth, the adjusting rod 2 is moved upward by the telescopic device 3. The adjusting rod 2 moves the pressure cap 6 upward through the second connecting sleeve 8, releasing the seal on each water collection box 5, allowing water samples at the corresponding depth to be poured into the water collection box 5. After the water samples are collected, the adjusting rod 2 is returned to its original position by the telescopic device 3, causing the pressure cap 6 to seal the water collection box 5 again. Then, the installation cylinder 1 is removed from the water, and no water will enter the water collection box 5 at this time.

[0021] The above process can obviously prevent water samples from different depths before and after water collection from entering the water collection box 5, thus improving the sampling accuracy.

[0022] like Figure 1 As shown, the lower end of the mounting cylinder 1 has an opening 11. The opening 11 at the bottom of the mounting cylinder 1 allows impurities in the water entering the mounting cylinder 1 to be discharged in a timely manner, preventing impurities from clogging the inside of the mounting cylinder 1 and affecting its durability.

[0023] The outer wall of the mounting cylinder 1 is equipped with a height scale (not shown in the figure). By setting its own height scale, the water depth of the mounting cylinder 1 and the height position of each water collection box 5 can be adjusted without the need for an external measuring ruler, thus improving convenience.

[0024] like Figure 2 As shown, a pin 12 is vertically connected to the side of the pressure cap 6; a guide sleeve 13 is fixed to the side of the water dispensing box 5; the pin 12 and the guide sleeve 13 are inserted into each other. By limiting the pin 12 and the guide sleeve 13, the problem of the pressure cap 6 and the water dispensing box 5 shifting and misaligning during the adjustment process, which would prevent the pressure cap 6 from sealing the water dispensing box 5 tightly, can be avoided.
