Description

Technical Field

[0001] The utility model relates to the technical field of sulfide detection in water, in particular to a fixing frame for a sulfide detection instrument in water. Background Art

[0002] Sulfides in water are mainly produced by the reduction of sulfate by bacteria under anaerobic conditions, and some are produced by the decomposition of sulfur-containing organic matter. With the rapid development of my country's industry and chemical industry, a large amount of sulfides enter the wastewater, posing a great threat to the ecological environment. As my country's requirements for environmental protection are further improved, and in order to ensure the safety of domestic water, it is very necessary to adopt appropriate methods to test domestic and production water. The sulfide content in water has a great impact on the quality of water. The determination of the sulfide content in water is of great significance to the judgment of water quality.

[0003] For example, a water sulfide detection device recorded in the patent document with patent publication number CN115753947A is a device that is configured to detect sulfides in water by setting a fixed plate with threaded holes at both ends, one end of which is threadedly connected to the edge of the hull, and the other end of which is threadedly connected to a shell assembly. The shell assembly is placed in water, and driven by the detection ship, the shell assembly is fully detected in the water area to be detected. The water samples detected are sufficient, and the detection area can also cover most areas of the water area to be detected, so that the detection results are more accurate, which is beneficial to the subsequent management and application of water resources. However, the device can only detect the surface of the water body or the water body taken out, and cannot directly detect the sulfide content in deeper water. At the same time, when installing the sulfide detection instrument, it is necessary to set a fixed plate with threaded holes at both ends, and one end of which is threadedly connected to the edge of the hull. However, this method is too troublesome to install, and the bolts may damage the hull.

[0004] Based on this, a fixing bracket for a water sulfide detection instrument is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, Figure 1-Figure 4 As shown, a fixing bracket for an instrument for detecting sulfide in water includes a fixing bracket body 1 and a sulfide detector 6. One end of the fixing bracket body 1 is provided with a fixing mechanism 2 for fixing the device on a ship, which can conveniently install the sulfide detection instrument on the hull. One end of the fixing bracket body 1 is provided with an adjustment mechanism 3 for detecting sulfide in water at different depths, which can detect sulfide in water at different depths.

[0026] In one embodiment, Figure 2As shown, the fixing mechanism 2 includes a first fixing plate 201, a threaded rod 202, a second fixing plate 203 and a turntable 204. The bottom of the fixing frame body 1 is fixedly connected to the first fixing plate 201, one end of the fixing frame body 1 is threadedly connected to the threaded rod 202, one end of the threaded rod 202 is rotatably connected to the second fixing plate 203, and the other end is fixedly connected to the turntable 204. When the sulfide detection instrument needs to be fixed on the hull, the fixing frame body 1 is placed on the hull, and the turntable 204 is rotated so that the second fixing plate 203 can be moved left and right through the threaded rod 202. One end of the second fixing plate 203 and one end of the first fixing plate 201 form a clamp, which makes it convenient to fix the sulfide detection instrument on the hull through the fixing frame body 1.

[0027] In one embodiment, Figure 2 As shown, one end of the first fixing plate 201 and the second fixing plate 203 is provided with multiple groups of protrusions, which can increase the friction between the first fixing plate 201 and the second fixing plate 203 and prevent the fixing frame body 1 from falling off the hull.

[0028] In one embodiment, Figure 3 As shown, the adjustment mechanism 3 includes a drive motor 301, a connecting rod 302, a rotating shaft 303, a gear 304 and a rack 305. The drive motor 301 is fixedly connected to the inside of one end of the fixed frame body 1, and one end of the drive motor 301 is fixedly connected to the connecting rod 302. One end of the connecting rod 302 is fixedly connected to the rotating shaft 303. One end of the rotating shaft 303 is rotatably connected to the fixed frame body 1. The surface of the connecting rod 302 is fixedly connected to the gear 304. The surface of the gear 304 is meshed and connected with multiple groups of racks 305. One end of the rack 305 is fixedly connected to the connecting plate 4. When sulfide detection is required for water at a deeper position, the drive motor 301 is started, and the drive motor 301 drives the connecting rod 302 to rotate, and the connecting rod 302 drives the gear 304 to rotate. When the gear 304 rotates, it can drive the rack 305 on the connecting plate 4 to move up and down, so that the detection mechanism 5 can be moved to waters of different depths through the connecting plate 4 to perform sulfide detection.

[0029] In one embodiment, Figure 3 As shown, the connecting rod 302 forms a rotating structure with the fixing frame body 1 through the rotating shaft 303. When the connecting rod 302 rotates, the rotating shaft 303 can support one end of the connecting rod 302 and prevent the connecting rod 302 from shaking during rotation.

[0030] In one embodiment, Figure 4As shown, one end of the connecting plate 4 is provided with a detection mechanism 5 for detecting sulfide in water, and the detection mechanism 5 includes a fixed sleeve 501, a water inlet groove 502, a lifting rod 503 and a sealing ring 504. One end of the connecting plate 4 is fixedly connected to the fixing sleeve 501, and a water inlet groove 502 is provided on the surface of the fixing sleeve 501. The interior of the water inlet groove 502 is fixedly connected with a lifting rod 503, and one end of the lifting rod 503 is fixedly connected with a sealing ring 504. A sulfide detector 6 is fixedly connected to one side of the inner wall of the water inlet groove 502. When the detection is performed, the lifting rod 503 is started, and the lifting rod 503 drives the sealing ring 504 to move up and down, and moves the sealing ring 504 to the bottom of the water inlet groove 502, so that the water in this water area can enter the water inlet groove 502, and then the water is tested for sulfide through the sulfide detector 6.

[0031] In one embodiment, Figure 4 As shown, the inner wall size of the water inlet groove 502 is consistent with the outer wall size of the sealing ring 504. When the sealing ring 504 slides inside the water inlet groove 502, the water inlet groove 502 can limit the sliding of the sealing ring 504 to prevent the sealing ring 504 from shaking inside the water inlet groove 502.

[0032] In one embodiment, Figure 4 As shown, a water quality sensor is provided at one end of the sulfide detector 6, which is based on the electrochemical amperometric principle, has a short response time, high resolution, is not affected by salinity, turbidity and color, and can well detect the sulfide content in water.

[0033] Working principle: The above embodiment discloses a fixing bracket for a sulfide detection instrument in water, wherein, when the sulfide detection instrument needs to be fixed on the hull, the fixing bracket body 1 is placed on the hull, and the turntable 204 is rotated so that the second fixing plate 203 can move left and right through the threaded rod 202. One end of the second fixing plate 203 and one end of the first fixing plate 201 form a clamp, thereby facilitating the fixing of the sulfide detection instrument on the hull through the fixing bracket body 1. When it is necessary to perform sulfide detection on water at a deeper position, the drive motor 301 is started, and the drive motor 301 drives the connecting rod 302 to rotate. When the gear 304 rotates, the connecting rod 302 drives the gear 304 to rotate. When the gear 304 rotates, it can drive the rack 305 on the connecting plate 4 to move up and down, so that the detection mechanism 5 can be moved to waters of different depths through the connecting plate 4 to perform sulfide detection. When the detection is performed, the lifting rod 503 is started, and the lifting rod 503 drives the sealing ring 504 to move up and down, and moves the sealing ring 504 to the bottom of the water inlet tank 502, so that the water in this water area can enter the water inlet tank 502, and then the water is tested for sulfide through the sulfide detector 6 (the sulfide detector 6 is a prior art and will not be described here).

[0034] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
