Description

Technical Field

[0001] The utility model relates to the technical field of lake water quality detection devices, and more specifically to a lake water quality detection device. Background Technique

[0002] The water quality of lake water refers to the physical and chemical properties and dynamic characteristics of lake water. The physical properties of lake water mainly refer to water temperature, color, transparency, odor and taste. The chemical properties are determined by the gases, ions, molecules, colloidal substances, suspended solid components, microorganisms dissolved and dispersed in the lake water and the content of these substances. The main chemical components dissolved in lake water are similar to those of general natural water, and its evaluation indicators are also the same as those of natural water.

[0003] At present, when the existing lake water quality detection device is in use, the whole device is generally placed on the lake surface, so that the detection head is inserted into the lake water for detection work. However, there are still some problems in the use of the existing water quality detection device. Generally, the position of the detection head on the detection device is fixed. In this way, it is necessary to replace detection heads with different lengths according to the detection depth, resulting in inflexible use. Moreover, the disassembly and assembly operations will delay the detection time and affect the overall use effect. Therefore, a structure that can conveniently adjust the position of the detection head is needed to meet the water quality detection work at different depths. Content of the Utility Model

The detection head is electrically connected to the power supply box. A waterproof box is installed on the upper side of the floating board. A forward and reverse motor is installed inside the waterproof box. The output end of the forward and reverse motor is provided with a rotating rod passing through the floating board. The lower end of the rotating rod is provided with a lifting adjustment part connected to the detection head. A limiting plate is installed on the adjustment part of the lifting adjustment part. Limiting rods are installed on the left and right sides of the upper surface of the limiting plate, and the limiting rods penetrate through the plate wall of the floating board.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. The present utility model can conveniently supply power to the detection head through the cooperation of the solar panel and the power supply box to ensure normal operation. The setting of the floating plate can make the whole float on the lake surface, so that the detection head can be located in the lake water. According to the depth of the lake water, the lifting and adjusting member with a corresponding length can be selected. Under the cooperation of the positive and negative rotation motor, the rotating rod, the limiting plate and the limiting rod, the lifting and adjusting member can be controlled to drive the detection head to move up and down, so as to detect the water quality of the lake water at different depths. In this way, the position of the detection head can be directly adjusted in the water, saving the operation of repeatedly replacing support members with different lengths and improving the convenience of operation. The overall structure is flexibly matched, enhancing the overall use effect.

[0026] Wherein: A connection groove 13 corresponding to the rotating rod 9 is arranged at the upper end of the lifting adjustment part 10, and the rotating rod 9 and the lifting adjustment part 10 are connected by screws 14; The rotating rod 9 and the lifting adjustment part 10 can be conveniently combined through cooperation, so that the lifting adjustment part 10 with a suitable length can be selected according to the measurement needs, and the use is flexible.

[0027] Wherein: The lifting adjustment part 10 includes a threaded pipe 12, an adjustment screw rod 16 is installed in the threaded pipe 12 through internal thread 15 for limitation, a connecting plate 17 combined with the detection head 4 is arranged at the lower end of the adjustment screw rod 16, and the limiting plate 18 is fixedly connected to the rod wall of the adjustment screw rod 16; The threaded pipe 12 can be rotated under the limitation of the adjustment screw rod 16 through cooperation, so that the adjustment screw rod 16 can be controlled to move under the action of the internal thread 15, achieving the effect of lifting and adjusting the detection head 4.

[0028] Wherein: Connecting sleeves 19 screwed with the limiting rods 11 are arranged on the left and right sides of the upper side of the limiting plate 18; The position of the limiting rod 11 can be fixed by the threaded combination between the side end of the limiting rod 11 and the inner wall of the connecting sleeve 19, which is convenient for disassembling and assembling the limiting rod 11, so that the limiting rod 11 with a corresponding length can be selected according to the use needs of the lifting adjustment part 10.

[0029] Wherein: Floating blocks 20 are arranged at the four corners of the lower side of the floating board 1; The buoyancy of the floating board 1 can be enhanced through cooperation.

[0030] Wherein: Fixed plates 21 are installed on the left and right sides of the lower side of the floating board 1, a pulling rope 23 is installed on the lower side of the fixed plate 21 through a hanging ring 22, and a weight block 24 is connected to the lower end of the pulling rope 23; The stability of the floating board 1 can be increased by setting the weight block 24 through cooperation, preventing it from tipping over under the influence of wind and waves.

[0033] Working principle of the first embodiment of the present utility model: When conducting lake water quality detection, first select a lifting adjustment member 10 with an appropriate length, then combine the detection head 4 with the connecting plate 17 at the side end, and combine the limiting rod 11 with the connecting sleeve 19 on the limiting plate 18. Then, combine the connecting groove 13 at the upper end of the lifting adjustment member 10 with the rotating rod 9, and fix the connection position through the screw 14. At the same time, the limiting rod 11 passes through the floating plate 1 and the support plate 6 from bottom to top, so that the detection head 4 can be arranged below the floating plate 1. Then, connect the connecting wire of the detection head 4 to the power supply box 3, and supply power to it through the power supply box 3 to enable it to work normally. After completion, place the floating plate 1 on the lake surface at the detection position, so that the detection head 4 and the weight block 24 fall into the water. In this way, the cooperation between the floating block 20 and the weight block 24 can improve the stability of the position of the floating plate 1 and prevent it from tipping over. Then, the forward and reverse motor 8 can be started. By rotating the rotating rod 9, the threaded tube 12 on the lifting adjustment member 10 can be controlled to rotate. In this way, under the limitation of the limiting rod 11, the adjusting screw rod 16 can be controlled to move downward, so as to adjust the position of the detection head 4, enabling it to detect the water quality of lake water at different depths. Through such a structural cooperation, it is not necessary to repeatedly replace different-length support members to adjust the position of the detection head 4, which is convenient to use, effectively improves the flexibility of water quality detection operations, and has a simple structural cooperation, improving the overall use effect.
