Description

Technical Field

[0001] This invention relates to the field of water quality analysis technology, specifically to a water quality analysis device. Background Technology

[0002] Coal mine water quality analysis equipment is a specialized instrument for water quality testing in mining environments. It is mainly used to quickly analyze the type of water source, chemical composition, and recharge source of underground water inrush.

[0003] However, the following drawbacks still exist: existing water quality analysis devices require water samples to be collected before being sent to the laboratory for analysis, which is inconvenient for timely testing and analysis of water samples, resulting in low accuracy of water quality analysis results. Moreover, most existing water quality analyses directly deliver water to the testing equipment for testing. During the collection or storage of water in underground coal mines, suspended particles and dissolved substances in the water may settle or stratify due to gravity. If the composition and concentration of different parts of the water sample are not kept consistent in time, it may lead to deviations in the test results. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a water quality analysis device, primarily to solve the problem that its internal filtration and purification mechanism is lacking, requiring separate purification of the separated liquid before discharge, which leads to a rather cumbersome process.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A water quality analysis device includes a base plate and a water quality analyzer. A housing is fixedly connected to the upper surface of the base plate, and a connecting pipe is fixedly connected to one side of the housing. A water pumping assembly is provided on the base plate and is connected to the connecting pipe. A stirring tank is provided inside the housing. Two fixing blocks are fixedly connected to the bottom outer wall of the stirring tank, and a rotating shaft is fixedly connected between the two fixing blocks. A T-shaped frame is fixedly connected to the inner wall of the housing, and the rotating shaft is rotatably connected to the top of the T-shaped frame. Return torsion springs are sleeved on the outer sides of both ends of the rotating shaft, and the two ends of the return torsion springs are respectively fixed to the fixing blocks and the T-shaped frame. A baffle is movably connected to one side of the mixing tank via two spring hinges. The interior of the housing is equipped with a pushing assembly that rotates the mixing tank. A threaded groove is provided on the top of the housing, and a semi-threaded screw is provided in the threaded groove. The threaded part at the bottom of the semi-threaded screw is threadedly connected to the threaded groove, and the vertical part at the top of the semi-threaded screw is gap-connected to the threaded groove. The bottom end of the semi-threaded screw extends into the housing and is fixed to a mixing frame by bolts. The top end of the semi-threaded screw passes through the housing and is fixedly connected to a limit block. A water storage tank is fixedly connected to the bottom inner wall of the housing, and the detection end of the water quality analyzer passes through the water storage tank.

[0006] Furthermore, the pumping assembly includes a fixed frame, which is fixed to the upper surface of the base plate by bolts. A cylinder is fixedly connected to the fixed frame, and a piston is movably connected inside the cylinder. A connecting shaft is fixedly connected to the top of the piston. An electric push rod is fixedly connected to the top of the fixed frame, and the extended end of the electric push rod passes through the fixed frame and is fixed to the connecting shaft. A water inlet pipe is fixedly connected to the bottom of the cylinder, and a filter screen is snapped onto one end of the water inlet pipe.

[0007] Based on the aforementioned scheme, a check valve is fixed to one end of the water inlet pipe near the bottom of the cylinder and to the connecting pipe.

[0008] As a further embodiment of the present invention, the pushing assembly includes a connecting rod rotatably connected to the inner wall of one side of the housing. One end of the connecting rod is keyed to a gear. A triangular block is fixedly connected to the outer wall of one side of the housing. A motor is fixedly connected to the upper surface of the triangular block, and one end of the motor output shaft is fixed to the connecting rod. A sliding groove is formed on the inner wall of one side of the housing. A rack is movably connected in the sliding groove, and the gear meshes with the rack. A push block is fixedly connected to the top of the rack, and the push block contacts the bottom outer wall of the mixing tank.

[0009] Furthermore, a water outlet is provided on one side of the shell, and a water outlet pipe is fixedly connected to the water outlet and connected to the water storage tank.

[0010] Based on the aforementioned scheme, a waterproof shell is detachably connected to the bottom inner wall of the housing by bolts, and the water quality analyzer is located inside the waterproof shell. An inclined block is fixed to the bottom of the water storage tank.

[0011] As a further embodiment of the present invention, the base plate is fixedly connected with multiple casters, which are symmetrically distributed. The upper surface of the base plate is fixedly connected with a handrail, and both sides of the fixing frame are fixedly connected with elastic hooks.

[0012] Furthermore, the stirring rack can extend into the stirring tank, which is located above the water storage tank, and the diameter of the limiting block is larger than the diameter of the threaded groove.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a water quality analysis device with the following advantages: 1. The mixing tank in this invention can eliminate differences in water sample concentration. By manually rotating the semi-threaded screw, the mixing rack can stir the water sample, preventing suspended particles and dissolved substances in the water from settling or stratifying due to gravity, avoiding deviations in test results due to different sampling locations, and improving the reliability of test results.

[0014] After mixing is complete, the semi-threaded screw can remove the mixing rack from the mixing tank and provide auxiliary positioning, preventing it from interfering with subsequent processes and ensuring the smooth operation of the device.

[0015] 2. This invention uses an inlet pipe to penetrate deep into the water source, allowing the pumping component to extract the water sample to be tested. At the same time, the filter screen can filter out larger impurities to avoid interference with subsequent testing. Check valves are installed on the inlet pipe and connecting pipe to prevent water sample backflow, ensuring that the water sample flows along the predetermined path and maintaining stable operation of the device.

[0016] 3. This invention tilts the mixing tank by pushing the component, allowing the water sample to flow smoothly into the storage tank, making it easier for the water quality analyzer to detect it and reducing manual operation.

[0017] 4. This invention not only guides the water sample in the storage tank through the inclined block, allowing the water sample to be discharged more smoothly through the outlet pipe and improving the water sample discharge efficiency, but also protects the water quality analyzer through the waterproof shell, extending its service life and further ensuring the long-term stable operation of the testing work.

[0018] 5. This invention not only enables the device to be moved to the required location for sampling and testing, but also allows the device to perform the entire process of extracting, stirring, and testing water samples without the need for repeated handling and transfer using multiple devices, which is time-consuming, labor-intensive, and affects the testing results.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-5A water quality analysis device includes a base plate 7 and a water quality analyzer 24. The water quality analyzer 24 is a YHS5(A) intrinsically safe mining water quality analyzer. A housing 9 is bolted to the upper surface of the base plate 7. A connecting pipe 2 is fixed to one side of the housing 9. A pumping assembly is provided on the base plate 7 and is connected to the connecting pipe 2. The pumping assembly includes a fixing frame 1, which is bolted to the upper surface of the base plate 7. A cylinder 3 is bolted to the fixing frame 1. A piston 12 is slidably connected inside the cylinder 3. A connecting shaft 11 is welded to the top of the piston 12. An electric push rod 10 is bolted to the top of the fixing frame 1, and the extended end of the electric push rod 10 passes through the fixing frame 1 and is connected to the connecting shaft 11. The bottom end of the cylinder 3 is fixedly connected to a water inlet pipe 4, which extends into the water source to be tested. When the electric push rod 10 retracts, the connecting shaft 11 drives the piston 12 to slide upward along the cylinder 3, generating negative pressure until the piston 12 moves above the interface with the connecting pipe 2. At this time, water enters the cylinder 3 through the water inlet pipe 4. One end of the water inlet pipe 4 is connected to a filter screen 13, which can filter the water sample entering the water inlet pipe 4 to prevent large impurities from entering. Check valves 14 are fixed on the end of the water inlet pipe 4 near the bottom of the cylinder 3 and on the connecting pipe 2 to prevent the water sample from flowing back.

[0023] Specifically, the interior of the shell 9 is equipped with a mixing tank 19. The water sample in the cylinder 3 enters the mixing tank 19 through the connecting pipe 2. Two fixing blocks 26 are bolted to the bottom outer wall of the mixing tank 19. A rotating shaft 27 is bolted between the two fixing blocks 26. A T-shaped frame 29 is bolted to the inner wall of the shell 9, and the rotating shaft 27 is rotatably connected to the top of the T-shaped frame 29. Returning torsion springs 28 are sleeved on the outer sides of both ends of the rotating shaft 27, and the two ends of the return torsion springs 28 are respectively fixed to the fixing blocks 26 and the T-shaped frame 29. One side of the mixing tank 19 is rotatably connected to two spring hinges. Baffle 23 is sealed to housing 9 via a gasket. Housing 9 contains a drive assembly that rotates the mixing tank 19. A threaded groove is formed on the top of housing 9, housing a semi-threaded screw 17. The threaded portion at the bottom of the semi-threaded screw 17 is threaded into the threaded groove, while the vertical portion at the top of the semi-threaded screw 17 is loosely connected to the threaded groove. A stirring frame 18 is bolted into housing 9 at the bottom end of the semi-threaded screw 17. The operator manually moves the top of the semi-threaded screw 17, causing the stirring frame 18 to rotate and stir the water sample inside the mixing tank 19, eliminating concentration differences. To prevent suspended particles and dissolved substances in the water from settling or stratifying due to gravity, stirring breaks up this stratification, ensuring that the composition and concentration of each part of the water sample remain consistent. This avoids deviations in test results due to different sampling locations. After stirring, pull the semi-threaded screw 17 upwards. When the initial threaded portion of the semi-threaded screw 17 enters the thread groove, rotate the semi-threaded screw 17 to move it upwards along the thread groove until the stirring frame 18 is removed from the stirring box 19. At this point, the moved stirring frame 18 is assisted in positioning to prevent it from interfering with subsequent processes. The top end of the screw 17 passes through the housing 9 and is fixed with a limit block 16 by bolts. The limit block 16 can limit the height of the semi-threaded screw 17 to prevent it from detaching from the housing 9. The bottom inner wall of the housing 9 is fixed with a water storage tank 21 by bolts, and the detection end of the water quality analyzer 24 passes through the water storage tank 21. The push component push block pushes the bottom of the mixing tank 19, causing it to rotate upwards, and the reset torsion spring 28 deforms. At this time, the mixing tank 19 tilts, so that the water in the mixing tank 19 flows into the water storage tank 21. The water sample in the water storage tank 21 is tested by the water quality analyzer 24.

[0024] It should be noted that the pushing component includes a connecting rod 32, which is rotatably connected to the inner wall of one side of the housing 9. A gear 34 is keyed to one end of the connecting rod 32. A triangular block 31 is fixed to the outer wall of one side of the housing 9 by bolts. A motor 6 is fixed to the upper surface of the triangular block 31 by bolts, and one end of the output shaft of the motor 6 is fixed to the connecting rod 32. A sliding groove 30 is provided on the inner wall of one side of the housing 9. A rack 33 is slidably connected in the sliding groove 30, and the gear 34 meshes with the rack 33. A push block is fixed to the top of the rack 33 by bolts, and the push block contacts the bottom outer wall of the mixing tank 19. When the motor 6 rotates, the connecting rod 32 drives the gear 34 to rotate, thereby causing the rack 33 to move upward along the sliding groove 30. At this time, the push block on the rack 33 pushes the mixing tank 19 upward.

[0025] In this invention, a water outlet is provided on one side of the housing 9, and a water outlet pipe 25 is fixedly connected to the water outlet and connected to the water storage tank 21. A waterproof shell 22 is detachably connected to the bottom inner wall of the housing 9 by bolts, and the water quality analyzer 24 is located inside the waterproof shell 22, which can protect the water quality analyzer 24. An inclined block 20 is fixed to the bottom of the water storage tank 21, which can guide the water sample in the water storage tank 21, so that the water sample can be discharged more smoothly through the water outlet pipe 25. Multiple casters are fixed to the bottom plate 7 by bolts. 5. Multiple casters 5 are symmetrically distributed, and two of the casters 5 have a self-locking function, which not only facilitates the movement of the device, but also makes it easy for the staff to position the device in the required position. The upper surface of the base plate 7 is fixed with a handrail 8 by bolts, which makes it easy for the staff to push the device. Both sides of the fixed frame 1 are fixed with elastic hooks 15 by bolts. The elastic hooks 15 can be used to hang related tools or accessories for easy access. The mixing rack 18 can extend into the mixing box 19, which is located above the water storage tank 21. The diameter of the limiting block 16 is larger than the diameter of the threaded groove.

[0026] The working principle of this embodiment is as follows: When water quality testing is required, the universal wheels 5 are used to assist the operator in moving the device to the required testing position, so that the inlet pipe 4 is inserted into the water source to be tested. Then, the electric push rod 10 is activated, and the electric push rod 10 retracts, causing the connecting shaft 11 to drive the piston 12 to slide upward along the cylinder 3, forming a negative pressure until the piston 12 moves above the interface with the connecting pipe 2. At this time, water enters the cylinder 3 through the inlet pipe 4 and the filter screen 13, and then enters the mixing tank 19 through the connecting pipe 2. Then, the operator manually rotates the top of the semi-threaded screw 17, causing the mixing frame 18 to rotate and stir the water sample in the mixing tank 19, eliminating concentration differences and preventing suspended particles and dissolved substances in the water from settling or stratifying due to gravity. After stirring is completed, the semi-threaded screw is pulled upward. 17. When the initial threaded portion of the semi-threaded screw 17 enters the threaded groove, rotate the semi-threaded screw 17 to move it upward along the threaded groove until the stirring frame 18 moves out of the stirring box 19. At this time, the moved stirring frame 18 is assisted in positioning. Then, start the motor 6. The rotation of the motor 6 causes the connecting rod 32 to drive the gear 34 to rotate, thereby causing the rack 33 to move upward along the slide groove 30. At this time, the push block on the rack 33 pushes the bottom of the stirring box 19, causing it to rotate upward, and the return torsion spring 28 deforms. At this time, the stirring box 19 tilts, causing the water in the stirring box 19 to flow into the water storage tank 21. The water sample in the water storage tank 21 is tested by the water quality analyzer 24. The tested water sample is discharged through the outlet pipe 25 along the slope of the inclined block 20.
