Description

Technical Field

[0001] The present invention relates to the field of river water detection, and particularly to a river water detection device for water conservancy projects. Background Art

[0002] Human beings are inseparable from water in their living and production activities, and the quality of water is closely related to human health. Natural water is a solution with a very complex chemical composition, containing soluble substances (such as salts, soluble organic matters, and soluble gases, etc.), colloidal substances (such as silica gel, humic acid, clay mineral colloidal substances, etc.), and suspended matters (such as clay, aquatic organisms, sediment, bacteria, algae, etc.). The salt content of surface water is relatively low, but it is easily polluted; groundwater is relatively clean, but it contains more dissolved minerals.

[0003] Currently, river water detection is mainly carried out by using a wired device, which is fixed at a certain position and detects the current position at different time intervals. However, the change rate of water is fast and the water flow environment is complex, so single-position detection cannot be representative and has a large error. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a river water detection device for water conservancy projects, aiming to solve the problem that currently, due to the fast change rate of water and the complex water flow environment, single-position detection cannot be representative and has a large error.

[0010] According to one aspect of the above technical solution, the detection mechanism includes an installation box, a push rod arranged in the installation box, and a detection rod arranged on the moving end of the push rod, and the push rod is fixedly connected to a partition plate in the installation box.

[0036] Embodiment 1

[0037] Please refer to Figures 1 - 7 , which shows the structural schematic diagram of the river water detection device for water conservancy projects provided in Embodiment 1 of the present invention. The river water detection device for water conservancy projects includes a support mechanism spanning both banks of the river, a detection mechanism 5 provided on the support mechanism, and a sampling mechanism 6 provided in the detection mechanism 5, where:

[0038] In order to achieve multi-point detection and multi-point sampling of the detection mechanism 5 and the sampling mechanism 6, the support mechanism includes support components symmetrically arranged on both banks of the river and a connecting rod 4 connecting the support components on both banks of the river. The detection mechanism 5 is arranged on the connecting rod 4 and can move along the length direction of the connecting rod 4 to achieve multi-point detection of the river water.

[0039] In order to be stably inserted into the river water, the support component includes a vertical rod 1, a moving column 3 arranged on the vertical rod 1, and a plurality of stabilizing forks 2 arranged at the bottom of the vertical rod 1. Both ends of the connecting rod 4 are fixedly connected to the moving column 3. In this embodiment, in order to enable the vertical rod 1 to stably maintain a vertical state in the river, the number of stabilizing forks 2 is three, which are evenly arranged at the bottom of the vertical rod 1 to form a stable triangular support, and the bottom of both the stabilizing forks 2 and the vertical rod 1 are sharpened to facilitate insertion into the river bottom. Among them, the moving column 3 can also move up and down along the length direction of the vertical rod 1 to adjust the detection and sampling depths of the detection structure and the sampling mechanism 6.

[0040] In order to achieve the detection function, the detection mechanism 5 includes an installation box 52, a push rod 55 arranged in the installation box 52, and a detection rod 56 arranged on the moving end of the push rod 55. In order to achieve multi-point detection, the installation box 52 is provided with a slider 51 installed on the connecting rod 4, and a box door 53 is also arranged on one side of the installation box 52. The box door 53 faces the sampling mechanism 6, so that after the sampling mechanism 6 completes sampling, the sample inside can be taken out by opening the box door 53 for further detection.

[0041] Furthermore, the interior of the installation box 52 is divided into a detection space for accommodating the detection mechanism 5 and a sampling space for accommodating the sampling mechanism 6 by setting a partition plate 54. The push rod 55 is fixed to the partition plate 54 and drives the detection rod 56 to protrude from the bottom of the installation box 52 and enter the river water through the moving end to achieve real-time detection. By electrically controlling the movement of the slider 51 on the installation box 52 on the connecting rod 4, simultaneously electrically controlling the downward movement of the detection rod 56 for detection, and controlling the movement of the moving column 3 on the vertical rod 1, multi-point and multi-depth detection of the river water is achieved, replacing the traditional single-position measurement method, making the measurement results more accurate and improving the reliability of detection.

[0042] In order to make the detection structure more precise, a sampling mechanism 6 is equipped in the installation box 52 to facilitate river water sampling for further analysis. The sampling mechanism 6 includes a fixing plate 62 fixedly connected to the partition plate 54, a number of test tubes 68 arranged on the fixing plate 62, and a water absorption component arranged between the number of test tubes 68. The fixing plate 62 is vertically and fixedly connected to the partition plate 54 and is arranged parallel to the connecting rod 4. A number of test tubes 68 are also arranged circumferentially at the bottom of the fixing plate 62. One end of the water absorption component is arranged at the center of the fixing plate 62, and the test tubes 68 are arranged around the water absorption component. When the detection rod 56 moves downward, it drives the end of the water absorption component away from the test tubes 68 to move into the river water, thereby sampling the river water. It should be noted that a transmission piece is also arranged on the side of the fixing plate 62 away from the test tubes 68. The rotating piece 69 is sleeved on the end of the water absorption component close to the test tubes 68 and has a notch in the middle to expose the pipe orifice of one of the test tubes 68 and cover the pipe orifices of the other test tubes 68. "Exposing the pipe orifice of one of the test tubes 68" facilitates the water absorption component to inject the sampled river water into the test tube 68.

[0043] To sample the river water, the water absorption component includes a water suction pipe 63, a water pump 66 arranged on the water suction pipe 63, and an extension suction pipe 64 and a water outlet pipe 610 respectively arranged at both ends of the water suction pipe 63. The water outlet pipe 610 is arranged at the end of the water suction pipe 63 close to the test tubes 68 and is bent 180° so that the pipe orifice of the water outlet pipe 610 faces the pipe orifice of the test tube 68 not covered by the rotating piece 69. In addition, a first elastic member 67 is sleeved outside the extension suction pipe 64, and a connecting plate 65 is also arranged at the end of the extension suction pipe 64 away from the water suction pipe 63.

[0044] In order to drive the extension suction pipe 64 to move downward synchronously when the detection rod 56 moves downward, a pressing rod 61 is also arranged between the detection rod 56 and the extension suction pipe 64. The pressing rod 61 is in a "Z" shape. One end of the pressing rod 61 is arranged at the end of the detection rod 56 close to the push rod 55, and the other end is fixedly connected to the connecting plate 65. A filter screen is arranged at the end of the extension suction pipe 64 away from the water suction pipe 63. It should be noted that a track groove for the movement of the pressing rod 61 is also opened on the partition plate 54.

[0045] When the push rod 55 drives the detection rod 56 to move downward, the extension suction pipe is synchronously pulled through the pressing rod 61, and the extension suction pipe and the detection rod 56 protrude from the bottom of the installation box 52 at the same time and enter the river water. At this time, the first elastic member 67 is in a stretched state. At this time, the water pump 66 starts to work, sucks water through the extension suction pipe 64, filters out excess impurities by the filter screen, enters the water pump 66 through the extension suction pipe 64, flows through the suction pipe 63, and finally enters the test tube 68 below the outlet of the outlet pipe 610 through the outlet pipe 610 to complete the sampling. When the thrust of the push rod 55 ends, since the first elastic member 67 is in a stretched state and has a certain restoring force, the extension suction pipe 64 is pulled back by the first elastic member 67 to drive the detection rod 56 and the extension suction pipe 64 to reset.

[0046] In summary, a river water detection device for water conservancy projects proposed according to the present invention sets support components on both banks of the river, and uses the connecting rod 4 to enable the detection mechanism 5 to detect multiple locations of the river water. Moreover, since the sampling mechanism 6 moves along with the detection mechanism 5, it is possible to further perform multi-point sampling of the river water. Furthermore, the method of multi-point detection plus multi-point sampling improves the reliability of river water detection and eliminates the need for manual follow-up. Specifically, the support mechanism includes support components symmetrically arranged at both ends of the river bank and a connecting rod 4 connecting the support components on both banks, and the detection mechanism 5 is arranged on the connecting rod 4; when the detection rod 56 in the detection mechanism 5 moves, it synchronously drives the sampling mechanism 6 to move, and while realizing detection, samples the river water synchronously.

[0047] Embodiment 2

[0048] Please refer to Figures 8 - 9 , which shows the switching mechanism 7 proposed in Embodiment 2 of the present invention. The switching mechanism 7 acts on the outlet pipe 610 and is used to drive the outlet pipe 610 to rotate when the extension suction pipe 64 moves upward, so as to use a plurality of test tubes 68 to hold the sampled river water.

[0049] Specifically, the switching mechanism 7 includes a fixing rod 71 connected to one end of the extension suction pipe 64 away from the test tube 68, a sliding rod 72 that moves synchronously with the fixing rod 71, a sleeve 76 provided at one end of the sliding rod 72 away from the extension suction pipe 64, a fixing member 73 provided on the fixing plate 62, a rotating member 74 provided on the fixing member 73, and a threaded column 75 provided on the rotating member 74. The sleeve 76 is sleeved on the threaded column 75, and a compression member 77 is also provided on the threaded column 75. It should be noted that a "Z"-shaped thread is provided on the threaded column 75, and a moving ball is provided in the sleeve 76, and the rotating member 74 is clamped on the outlet pipe 610.

[0050] When the detection rod 56 drives the extension suction pipe 64 to take a sample, the fixed rod 71 and the moving rod are synchronously driven to move downward. At this time, the moving rod drives the sleeve 76 to move downward, and the moving ball moves downward along the "Z"-shaped thread. At this time, the compression member 77 is compressed downward. The moving ball moves to the bottom of the threaded column 75. As the extension suction pipe 64 resets, the sleeve 76 moves upward. Due to the trajectory of the "Z"-shaped thread, the rotating member 74 integrated with the threaded column 75 rotates within the fixed member 73. Since the rotating member 74 is clamped on the water outlet pipe 610, the water outlet pipe 610 and the rotating piece 69 are finally driven to rotate on the fixing plate 62. The notch of the rotating piece 69 is aligned with the next test tube 68, and the sampled river water is then injected into the empty test tube 68.

[0051] Embodiment III

[0052] Please refer to Figures 10 - 13 , as shown in the cleaning mechanism 8 proposed in Embodiment III of the present invention. The cleaning mechanism 8 is disposed within the detection space of the installation box 52 and on one side of the detection mechanism 5.

[0053] The cleaning mechanism 8 includes a fixed shell 81 disposed on the connecting rod 4, a rotating rod 83 meshed with the fixed shell 81, a reciprocating lead screw 85 movably connected to the rotating rod 83, a lifting frame 88 disposed on the reciprocating lead screw 85, an extension rod 89 disposed on the lifting frame 88, a second elastic member 811 sleeved on the extension rod 89, and a sponge ring 810 disposed at one end of the extension rod 89 away from the lifting frame 88. The sponge ring 810 is sleeved on the detection rod 56.

[0054] It should be noted that the fixed shell 81 is disposed on the connecting rod 4, and a rack 82 is provided on one side of the fixed shell 81. A gear 84 is provided at one end of the rotating rod 83 away from the reciprocating lead screw 85. The gear 84 is meshed with the rack 82. A flat belt 87 is further provided at one end of the rotating rod 83 away from the gear 84, and a pulley 86 is provided at one end of the reciprocating lead screw 85. When the gear 84 rotates on the rack 82, the gear 84 drives the rotating rod 83 to rotate, and then drives the pulley 86 to rotate through the flat belt 87. The pulley 86 drives the reciprocating lead screw 85 to rotate, so that the extension rod 89 drives the sponge ring to move along the length direction of the detection rod 56 to wipe the river water on the detection rod 56 and prevent it from interfering with the next detection. When the sponge ring 810 moves downward, the second elastic member 811 is pulled. When the sponge ring 810 moves to the bottom, the second elastic member 811 pulls back the sponge ring 810 to prepare for the next cleaning.
