Description

TECHNICAL FIELD

[0001] The utility model relates to water quality monitoring device technical field, concretely relates to a new water quality monitor for rainwater pipe network. BACKGROUND

[0002] Rainwater pipe network is an important part of urban drainage system, which is specially used for collecting and discharging rainwater to prevent urban waterlogging and flood disaster and ensure the normal operation of urban drainage system. The design of rainwater pipe network aims to quickly drain rainwater to prevent road waterlogging and flood disaster, so its pipe diameter is usually large enough to accommodate a large amount of rainwater in a short time. Rainwater pipe network collects rainwater from all corners of the city through a series of pipelines and pumping stations and other facilities, and finally discharges it into natural water bodies such as rivers and lakes.

[0003] Water quality monitor is an important tool for monitoring water quality changes. It monitors various parameters in water in real time through built-in sensors, such as dissolved oxygen, pH value, turbidity, ammonia nitrogen, chemical oxygen demand (COD), etc. These parameters can fully reflect the physical, chemical and biological properties of water quality, which is of great significance for assessing water quality, warning water pollution and developing protection measures. In rainwater pipe network, water quality monitor can timely detect and handle pollutants in rainwater to prevent them from entering natural water bodies, thereby protecting the balance of aquatic ecosystems and human health.

[0004] Although water quality monitor plays an important role in water quality monitoring, there are still two major problems in the application of existing water quality monitor in rainwater pipe network: first, installation is not convenient. The existing monitor often needs complex debugging and configuration during installation, which not only increases the difficulty and time consumption of installation, but also makes it difficult to find a suitable installation location due to the complex and variable environment of rainwater pipe network, thereby affecting the monitoring effect; second, it cannot be applied to drainage pipes of different sizes. The size of drainage pipes in rainwater pipe network varies from small diameter pipes to large diameter culverts, while the existing water quality monitor usually has fixed size and shape, which is difficult to adapt to drainage pipes of various sizes, which leads to the need for customizing different monitors for different sizes of pipes in actual application, greatly increasing the cost and complexity.

[0048] Embodiment 4

[0049] As Figure 4 , Figure 5 and Figure 6As shown, on the basis of embodiment 3, the utility model provides a technical scheme: preferably, support rod assembly 43 includes main rod 431, main rod 431 is fixedly connected with limit block 433 in symmetry, main rod 431 is fixedly connected with top block 432 on the side away from limit block 433, the inner chamber of connecting pipe 42 is symmetrically provided with sliding slot 421, and the limit block 433 of the same side is connected with sliding slot 421, drive rod assembly 41 includes handle two 411, handle two 411 is fixedly connected with threaded rod 412 in symmetry, and the threaded rod 412 of the same side is connected with main rod 431, a plurality of antiskid grooves are arranged on the outer surface of handle two 411 in annular array, the end surface of top block 432 is inclined, and top block 432 is made of rubber material.

[0050] In the embodiment, when the position adjustment of the two sliding blocks 33 is completed, the distance of the two support rod assemblies 43 needs to be adjusted according to the height of the inner chamber of the drain pipe 1, the worker applies force to the handle two 411 by hand, then drives the handle two 411 to rotate, then drives the two threaded rods 412 to rotate, then drives the two main rods 431 to move away from each other through the cooperation of the threaded rods 412 and the main rods 431, then drives the limit blocks 433 to slide in the inner chamber of the sliding slot 421, then drives the top block 432 to move towards the inner wall of the drain pipe 1, and then pushes the top block 432 into contact with the inner wall of the drain pipe 1, so that the device can be fixed in the inner chamber of the drain pipe 1.

[0052] The working principle of the novel water quality monitor for rainwater pipe network is specifically described below.

[0053] As Figures 1-12As shown in the rainwater in the sewer 1 cavity monitoring, first, the data collector 71 is placed on the bearing table 61, and then the water quality sensor 72 is connected with the lower part of the box 6, and then the water quality sensor 72 is connected with the data collector 71 through the wire, and then the data collector 71 is covered by the sealing shell 5, and the data collector 71 is located in the sealing shell 5, and then the sealing shell 5 is connected with the bearing table 61 through the cooperation of the bolt and the nut;

[0054] Then the staff adjusts the distance between the two sliding blocks 33 according to the width of the sewer 1 cavity, drives the sliding block 33 to slide in the cavity of the connecting block 32 by applying force to the sliding block 33, and drives the clamping block 342 to move towards the spring 343 when the sliding block 33 slides, and then drives the spring 343 to contract, When the clamping block 342 contacts the limiting groove 331, the spring 343 will be stretched under the action of the spring force of the spring 343, and then the clamping block 342 will be pushed to the limiting groove 331, so that the position of the sliding block 33 in the cavity of the connecting block 32 can be limited, and then the staff rotates the handle 346 by operating the handle 346, and drives the threaded block 345 to rotate by the handle 346, and then changes the position of the threaded block 345 in the cavity of the shell 341, drives the connecting disc 344 to move towards the spring 343, and then applies force to the spring 343, so that the spring 343 pushes the clamping block 342 to move towards the limiting groove 331, and then the position of the sliding block 33 in the cavity of the connecting block 32 can be locked by the cooperation of the clamping block 342 and the limiting groove 331.

[0055] When the position adjustment of the two sliding blocks 33 is completed, the distance between the two support rod assemblies 43 needs to be adjusted according to the height of the sewer 1 cavity, the staff applies force to the handle 411 by hand, and then drives the handle 411 to rotate, and then drives the two threaded rods 412 to rotate, and then drives the two main rods 431 to move away from each other by the cooperation of the threaded rods 412 and the main rods 431, and then drives the limiting block 433 to slide in the cavity of the sliding groove 421, and then drives the top block 432 to move towards the inner wall of the sewer 1, and then pushes the top block 432 to contact with the inner wall of the sewer 1, so that the device can be fixed in the cavity of the sewer 1;

[0056] Since the floating plate 2 is located on the water, the water quality sensor 72 located on the lower side of the floating plate 2 is directly in contact with the rainwater, so that the rainwater can be monitored, and then the monitored data is transmitted to the data collector 71, so that the data can be saved and transmitted to the data center through the data collector 71, thereby facilitating the staff to monitor the quality of the rainwater in real time. When the water level in the inner cavity of the drain pipe 1 rises, the floating plate 2 is driven to move upward under the action of the buoyancy of the water, so that the device can be driven to move upward together through the floating plate 2, so that the sliding block 33 can slide upward in the inner cavity of the sliding rail block 31. When the water level in the inner cavity of the drain pipe 1 drops, the floating plate 2 is driven to move downward under the weight of the device, and then the sliding block 33 is driven to slide downward in the inner cavity of the sliding rail block 31, so that the water quality sensor 72 can always be located in the water, thereby improving the monitoring quality and stability. When some water accidentally flows into the inner cavity of the placing box 6, the water flows into the inner cavity of the one-way valve 621 through the water guide pipe 62, and then the water is discharged through the one-way valve 621, so as to avoid the water in the inner cavity of the placing box 6 from gathering and then damaging the electronic elements in the data collector 71.

[0057] It should be noted that the specific installation method of the data collector 71 and the water quality sensor 72 and the connection mode of the circuit and the control method are all conventional designs, which are the conventional design means of the designer.

[0058] The above has made a detailed description of the general utility model, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, without departing from the modification or improvement of the spirit of the utility model, it is within the protection scope of the utility model.
