Description

Technical Field

[0001] This utility model relates to the field of water body detection technology, specifically to a heavy metal detection device for water. Background Technology

[0002] Minamata disease (mercury contamination) and Itai-itai disease (cadmium contamination), both well-known illnesses, are caused by heavy metal pollution. Therefore, the prevention and control of heavy metal contamination is urgent, and water pollution is currently the most serious and pressing problem requiring a solution. The prevention and control of heavy metal contamination in water must prioritize heavy metal monitoring. In existing detection processes, when the heavy metal probe of a water monitoring device is placed in flowing water, the flowing water carries aquatic plants and impurities that interfere with the probe's normal operation. While filters are typically installed at the probe to avoid affecting its operation, the accumulation of aquatic plants on the filter obstructs water flow in the detection area, interfering with detection accuracy. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a water heavy metal detection device, which solves the problem that when existing heavy metal detection probes are placed in flowing water for detection, impurities and aquatic plants in the water obstruct the flow of water in the detection area, easily interfering with the detection accuracy.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A water heavy metal detection device includes a housing and a heavy metal detection probe extending into the inner cavity of the housing. A frustum-shaped mesh sleeve is fixedly installed at one end of the housing. A gear ring is rotatably connected to the housing. A plurality of turbine blades are evenly spaced on the outer surface of the gear ring. Under the impetus of water flow, the turbine blades can drive the gear ring to rotate. A mounting bracket is fixedly connected to the end face of the gear ring. The end of the mounting bracket away from the gear ring is rotatably connected to the end face of the frustum-shaped mesh sleeve. A blade plate is fixedly connected to the middle of the mounting bracket.

[0005] Preferably, a stepped groove is provided at the end of the housing away from the frustum mesh sleeve, and a filter plate is fixedly connected to the stepped groove.

[0006] Preferably, a connecting box is arranged on the housing through an intermediate tube, and the heavy metal detection probe extends into the inner cavity of the housing through the intermediate tube.

[0007] Preferably, a drive shaft is rotatably connected to the housing, a drive gear that meshes with the gear ring is fixedly mounted on the drive shaft, and a drive motor is drivenly connected to the end of the drive shaft away from the drive gear, and the drive motor is fixedly mounted inside the connecting box.

[0008] Preferably, the mounting bracket is provided with a groove, and the blade plate is engaged and arranged in the groove and fixedly connected to the mounting bracket by fixing screws.

[0009] (III) Beneficial Effects This utility model has the following beneficial effects: This water heavy metal detection device effectively isolates aquatic plants and impurities in the water by using a truncated cone mesh sleeve at one end of the shell, ensuring the stable operation of the heavy metal detection probe within the shell cavity. Through the installation of turbine blades and a gear ring, the gear ring rotates in a specific direction under the propulsion of the flowing water, thereby driving the mounting frame to scrape away debris or aquatic plants from the truncated cone mesh sleeve. Simultaneously, because a blade plate is fixedly connected to the mounting frame, it can cut some debris or aquatic plants, effectively preventing the accumulation of aquatic plants or debris that could clog the truncated cone mesh sleeve and affect the heavy metal detection probe's ability to detect water within the shell cavity.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1This utility model provides a technical solution: a water heavy metal detection device, including a housing 1 and a heavy metal detection probe 4 extending into the inner cavity of the housing 1. A frustum mesh sleeve 2 is fixedly installed at one end of the housing 1. A gear ring 7 is rotatably connected to the housing 1. A plurality of turbine blades 8 are arranged at equal intervals on the outer surface of the gear ring 7. Under the push of water flow, the turbine blades 8 can drive the gear ring 7 to rotate. A mounting bracket 12 is fixedly connected to the end face of the gear ring 7. The end of the mounting bracket 12 away from the gear ring 7 is rotatably connected to the end face of the frustum mesh sleeve 2. A blade plate 13 is fixedly connected to the middle of the mounting bracket 12.

[0014] Reference Figure 1 and 2 As shown, in this scheme, the cone-shaped mesh sleeve 2 arranged at one end of the housing 1 can effectively isolate aquatic plants and impurities in the water, ensuring that the heavy metal detection probe 4 works stably in the inner cavity of the housing 1; through the turbine blades 8 and the toothed ring 7, the toothed ring 7 can rotate in a direction under the push of the flowing water, thereby driving the mounting frame 12 on it to scrape away debris or aquatic plants on the cone-shaped mesh sleeve 2; at the same time, since the blade plate 13 is fixedly connected to the mounting frame 12, it can cut some debris or aquatic plants, effectively preventing the accumulation of aquatic plants or debris from clogging the cone-shaped mesh sleeve 2 and affecting the detection of water by the heavy metal detection probe 4 in the inner cavity of the housing 1.

[0015] To prevent live organisms in the water from entering the inner cavity of the shell 1 and affecting normal detection during the heavy metal detection process of the heavy metal detection probe 4 inside the shell 1, refer to Figure 2 and 3 As shown, in this embodiment, a stepped groove is provided at the end of the housing 1 away from the frustum mesh sleeve 2, and a filter plate 3 is fixedly connected to the stepped groove.

[0016] Reference Figure 2 As shown, in this embodiment, a connecting box 5 is arranged on the housing 1 through an intermediate tube 6, and the heavy metal detection probe 4 extends into the inner cavity of the housing 1 through the intermediate tube 6. The intermediate tube 6 facilitates the connection of the wires or data cables of the detection probe to the power supply, control components, or data transmission components inside the connecting box 5, effectively protecting the wires or data cables.

[0017] Because the thrust generated by the water flow to rotate the turbine blades 8 and the gear ring 7 is limited, when a large amount of aquatic plants or debris accumulates on the conical mesh sleeve 2, the gear ring 7 cannot rotate due to the impact force of the water flow. Therefore, referring to... Figure 3As shown, in this embodiment, a drive shaft 10 is rotatably connected to the housing 1. A drive gear 9, which meshes with the gear ring 7, is fixedly mounted on the drive shaft 10. A drive motor 11 is connected to the end of the drive shaft 10 away from the drive gear 9. The drive motor 11 is fixedly mounted inside the connecting box 5. In practical applications, a camera can be installed at the end of the housing 1 near the truncated cone net sleeve 2 to monitor whether there is excessive accumulation of debris or aquatic plants on the truncated cone net sleeve 2. Then, based on the detection results, the drive motor 11 can be manually and remotely started, thereby driving the gear ring 7 to rotate continuously through the drive gear 9, thus completing the cleaning of the truncated cone net sleeve 2. Alternatively, the flow rate of the water inside the housing 1 can be monitored. When the flow rate is lower than a certain threshold, the drive motor 11 can be automatically started, thereby automatically driving the gear ring 7 to rotate, thus completing the cleaning of the truncated cone net sleeve 2.

[0018] Reference Figure 4 As shown, in this embodiment, the mounting bracket 12 is provided with a groove, and the blade plate 13 is engaged and arranged in the groove and fixedly connected to the mounting bracket 12 by fixing screws 14. By using fixing screws 14 to fix the blade plate 13 to the mounting bracket 12, it is convenient to disassemble, maintain or replace the entire blade plate 13 in the future.
