[0004] In the above solution, a protective layer can be pulled out from the protective device to cover the top surface of the controller and display screen for protection. A waterproof membrane is provided on top of the protective layer, which has good waterproof performance. Combined with the flexibility of the protective layer itself, the protective effect is even better. However, this solution has the following disadvantages: Since the water quality testing device operates on the water surface, rainwater, waves, or condensation can easily seep into the equipment from the gaps on the top surface of the water quality testing device, which can easily damage electronic components and sensors, thereby reducing the accuracy of the testing data. Utility Model Content

[0005] The purpose of this invention is to provide a water quality testing device with a protective structure to solve the problem that rainwater, waves, or condensate can easily seep into the device from the gaps on the top surface, causing damage to electronic components and sensors, since the water quality testing device operates on the water surface.

[0006] To achieve the aforementioned objectives, this utility model employs the following technical solution: a water quality testing device with a protective structure, comprising a mounting frame fixed to the top surface of the testing device body, a protective strip fixed to the outer wall of the mounting frame, a housing fixed to the front side of the testing device body, a waterproof membrane rotatably disposed on the inner wall of the housing, the waterproof membrane extending to the top surface of the housing, a fixing post fixed to the end of the waterproof membrane, several through holes opened on the top surface of the mounting frame, a pressing frame slidably connected to the inner wall of the mounting frame, and several... A connecting post is slidably inserted into a through hole. A spring is wound around the outer wall of the connecting post. The top end of the spring is fixed to the inner top surface of the mounting frame, and the bottom end of the spring is fixed to the top surface of the pressing frame. A pull frame is fixed to the top end of the connecting post. A receiving groove is opened on the top surface of the detection device body. The pressing frame is snapped into the receiving groove. An installation strip is fixed to the left side of the detection device body. Several connecting wires are fixed to the bottom surface of the installation strip. A detection head is fixed to the end of the connecting wire. The connecting wires and the detection heads are electrically connected to the detection device body.

[0007] Preferably, a sealing gasket is fixed to the inner bottom surface of the receiving groove.

[0008] Preferably, the bottom surface of the mounting strip is fixed with two limiting posts, the outer wall of the connecting line is slidably provided with a fixing plate, the top surface of the fixing plate is provided with two limiting holes, the limiting posts are slidably inserted into the limiting holes, and the fixing plate is fixed to the outer wall of the limiting posts by bolts.

[0009] Preferably, two floats are provided below the main body of the detection device, and a connecting plate is fixed between the two floats. The main body of the detection device is fixed to the top surface of the connecting plate.

[0010] Preferably, the left side of the connecting plate has a plurality of placement holes, and a counterweight is placed on the inner wall of the placement holes.

[0011] Preferably, the waterproof membrane is rotatably connected to the housing via a coil spring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the cooperation of the pressing frame, connecting column, spring, and pulling frame, the waterproof membrane can be stably pressed into the receiving groove, allowing it to tightly adhere to the top surface of the detection device body, forming a reliable seal. This effectively prevents rainwater, waves, or condensation from seeping into the device's interior through gaps in the top surface, avoiding damage to electronic components and sensors, and thus ensuring the accuracy of the detection data. The sealing gasket further enhances the seal between the receiving groove and the waterproof membrane, effectively preventing moisture from flowing through gaps to the top surface of the detection device body, avoiding damage to the display screen on the top surface due to moisture, thereby improving the working efficiency of the detection device body.

[0014] Second, the combination of the limiting pin and limiting hole allows operators to easily adjust the position of the fixing plate using bolts. This allows the fixing plate to limit and fix the connecting wire, effectively preventing the connecting wire from tangling due to water flow. This ensures stable water quality testing by the detection head, thereby improving the detection efficiency of the device. The float, through the connecting plate, forms a rigid structure that balances the impact of water flow, waves, and other external forces on the device, effectively preventing measurement errors or mechanical damage caused by shaking or tilting. The counterweight increases the weight of the device, making it more stable when floating on the water surface and effectively preventing it from tipping over, thus improving the overall stability of the device.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a water quality testing device with a protective structure includes a mounting frame 1, which is fixed to the top surface of the testing device body 2. A protective strip 3 is fixed to the outer wall of the mounting frame 1. A housing 4 is fixed to the front side of the testing device body 2. A waterproof membrane 5 is rotatably provided on the inner wall of the housing 4, extending to the top surface of the housing 4. A fixing post 6 is fixed to the end of the waterproof membrane 5. Several through holes 7 are opened on the top surface of the mounting frame 1. A pressing frame 8 is slidably connected to the inner wall of the mounting frame 1. Several connecting posts 9 are fixed to the top surface of the pressing frame 8. The connecting posts 9 are slidably inserted into the through holes 7. A spring 10 is wound around the wall. The top end of the spring 10 is fixed to the inner top surface of the mounting frame 1, and the bottom end of the spring 10 is fixed to the top surface of the pressing frame 8. A pull frame 11 is fixed to the top of the connecting column 9. A receiving groove 12 is opened on the top surface of the detection device body 2. The pressing frame 8 is snapped into the receiving groove 12. An installation strip 13 is fixed to the left side of the detection device body 2. Several connecting lines 14 are fixed to the bottom surface of the installation strip 13. A detection head 15 is fixed to the end of the connecting line 14. The connecting line 14 and the detection head 15 are electrically connected to the detection device body 2. A sealing gasket 16 is fixed to the inner bottom surface of the receiving groove 12.

[0022] In use, when water quality testing is required, the operator can first pull the pull frame 11, causing the pull frame 11 to drive the pressing frame 8 away from the receiving groove 12. Then, the fixing column 6 can be pulled. Through the linear movement of the fixing column 6, the waterproof membrane 5 is led out along the axis of the mounting frame 1, extending to the rear side of the mounting frame 1 and forming a temporary waterproof barrier. At this time, the traction force can be released. Relying on the energy storage characteristics of the spring 10, the pressing frame 8 is driven to apply a continuous and uniform pressing force to the waterproof membrane 5, realizing the dynamic sealing of the receiving groove 12 and pressing the waterproof membrane 5 into the receiving groove 12. Then, the pull frame 11 can be pressed, so that the pressing frame 8 is completely locked into the receiving groove 12, thereby waterproofing the top surface of the detection device body 2. Then, the detection device body 2 is deployed in the target water area through the buoyancy support structure, and the detection head 15 performs water quality testing.

[0023] During use, the waterproof membrane 5 is stably pressed into the receiving groove 12 by the cooperation of the pressing frame 8, connecting column 9, spring 10, and pulling frame 11. This ensures that the waterproof membrane 5 fits tightly against the top surface of the detection device body 2, forming a reliable seal. This effectively prevents rainwater, waves, or condensation from seeping into the device from the gaps on the top surface of the detection device body 2, avoiding damage to electronic components and sensors, and thus ensuring the accuracy of the detection data from the detection device body 2. The sealing gasket 16 further enhances the sealing between the receiving groove 12 and the waterproof membrane 5, effectively preventing moisture from flowing through the gaps to the top surface of the detection device body 2, avoiding damage to the display screen on the top surface of the detection device body 2 due to moisture, thereby improving the working efficiency of the detection device body 2.

[0024] like Figures 1-4 As shown, two limiting posts 17 are fixed to the bottom surface of the mounting strip 13. A fixing plate 18 is slidably provided on the outer wall of the connecting line 14. Two limiting holes 19 are opened on the top surface of the fixing plate 18. The limiting posts 17 are slidably inserted into the limiting holes 19. The fixing plate 18 is fixed to the outer wall of the limiting posts 17 by bolts. Two floats 20 are provided below the detection device body 2. A connecting plate 21 is fixed between the two floats 20. The detection device body 2 is fixed on the top surface of the connecting plate 21. Several placement holes 22 are opened on the left side of the connecting plate 21. A counterweight 23 is placed on the inner wall of the placement hole 22. The waterproof membrane 5 is rotatably connected to the housing 4 by a coil spring.

[0025] During use, the limiting post 17 and the limiting hole 19 allow the operator to easily adjust the position of the fixing plate 18 using bolts. This allows the fixing plate 18 to limit and fix the connecting wire 14, effectively preventing the connecting wire 14 from becoming entangled due to water flow. This ensures that the detection head 15 can stably perform water quality testing, thereby improving the detection efficiency of the detection device body 2. The float 20, through the connecting plate 21, forms a rigid structure that balances the impact of external forces such as water flow and waves on the detection device body 2, effectively preventing measurement errors or mechanical damage caused by shaking or tilting. The counterweight 23 increases the weight of the detection device body 2, making it more stable when floating on the water surface and effectively preventing it from tipping over, thus improving the stability of the detection device body 2.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
