[0002] The urban drainage system undertakes the important function of collecting and treating urban sewage. It is an important municipal infrastructure to safeguard people's lives, urban environment and urban safety. The safe and effective operation of the urban drainage network is also an important guarantee for the quality of the urban water environment.

[0003] When the drainage network is discharging sewage, it is necessary to monitor the liquid level in the sewage pipe to obtain accurate data for statistical sewage pipe data. Currently, the liquid level of the pipe is monitored by a liquid level monitor.

[0004] In the prior art, when monitoring the liquid level in a pipeline, a liquid level monitor is usually used to monitor the liquid level in the urban pipeline. However, most of the urban sewage pipelines are exposed outdoors and are exposed to wind and rain. Rain or dust may enter the liquid level monitor and cause damage to the liquid level monitor. The damaged monitor will not be able to provide data and needs to be disassembled for repair. Then the liquid level monitor must be installed on the urban sewage pipeline to monitor the liquid level. This situation may delay the timely collection of monitoring data, thereby greatly reducing the applicability of the monitoring device.

[0005] Therefore, in order to solve the above problems, a high-precision drainage network liquid level monitoring device is proposed. Utility Model Content

When using the device, by installing the installation pipe 1 on the urban drainage pipe, the water flow in the urban drainage pipe enters the wave-breaking tube 3 through the bottom of the wave-breaking tube 3 and the surface water inlet groove 21, and then uses the buoyancy of the floating block 6 and the floating slide bar 5 to make the floating slide bar 5 slide up and down in the sliding frame 4. The wave-breaking tube 3 reduces the impact force of the water flow, thereby affecting the floating slide bar 5 to slide up and down. The floating slide bar 5 slides up and down and drives the rack 8 to move up and down. The rack 8 drives the gear 9 to rotate. The gear 9 drives the gear 2 12 to rotate through the transmission rod, and drives the rack 8 to move up and down through the gear 2 12. The liquid level height is obtained by observing the scale plate 15 on the rack 2 11, which solves the problem that rainwater or dust enters the liquid level monitor outdoors, thereby causing the liquid level monitor to be damaged, and the damaged monitor will not be able to provide data, delaying the timely collection of monitoring data, thereby improving the applicability of the device.

[0025] Further, such as Figure 1 and Figure 4As shown, two flanges 17 are fixedly connected to the installation pipe 1, and an auxiliary component 18 is fixedly connected to one of the flanges 17; the auxiliary component 18 includes a fixing block 181; a screw 183 is rotatably connected to the fixing block 181; a fixing clamp 184 is fixedly connected to the bottom of the screw 183; a handle 182 is fixedly connected to the top of the screw 183; the fixing clamp 184 is arranged in an arc shape. By setting the auxiliary component 18, when using the device, the installation pipe 1 is transported to the installation position, and then the external pipe and the installation pipe 1 are aligned, and the screw 183 is rotated by the handle 182, and the screw 183 drives the fixing clamp 184 to move through the fixing block 181, so that the two fixing clamps 184 are firmly clamped on the external required pipe, so that the shaking generated by the installation pipe 1 during installation is reduced, thereby affecting the installation of the device, and then the flange 17 on the installation pipe 1 is fixed to the external pipe to be installed by external bolts, so that the installation is more convenient and the installation efficiency of the device is improved.

[0026] Further, such as Figure 1 and Figure 2 As shown, the mounting pipe 1 is detachably connected to a fixing plate 2; the sliding frame 4 is fixed to the mounting pipe 1 through the fixing plate 2; the sliding frame 4 is fixedly connected to a protective shell 13, and the gear 1 9, rack 1 8, transmission shaft 10, gear 2 12 and rack 2 11 are arranged in the protective shell 13; the slide bar 2 16 is slidably connected to the protective shell 13; a transparent observation plate 14 is arranged on the protective shell 13, and by arranging the protective shell 13 and the transparent observation plate 14, the movement of the scale plate 15 can be observed at all times through the transparent observation plate 14, which is conducive to observing the change of the liquid level, and the protective shell 13 reduces the dust from entering the protective shell 13, and the long-term accumulation affects the operation of the internal components.

[0027] Further, such as Figure 2 As shown, a plurality of water inlet grooves 21 are provided on the wave-breaking cylinder 3; filter screens 22 are provided at the bottom of the water inlet grooves 21 and the bottom of the wave-breaking cylinder 3. By providing the filter screens 22 and the water inlet grooves 21, the water inlet grooves 21 assist the water flow to enter the interior of the wave-breaking cylinder 3, so that the water flow quickly enters the interior of the wave-breaking cylinder 3, and the filter screens 22 reduce the impurities or debris in the water from entering the interior of the wave-breaking cylinder 3, thereby affecting the monitoring of the liquid level.

[0028] Further, such as Figure 2 and Figure 3As shown, the installation pipe 1 is connected with a water flow monitor 19; the water flow monitor 19 is arranged between the protective shell 13 and the flange 17; the transmission shaft 10 is rotatably connected with a fixed bracket 23; the fixed bracket 23 is arranged in the protective shell 13. By arranging the water flow monitor 19, when using the device, it is possible to detect whether there is water flowing through the installation pipe 1 and the speed of the water flow, so that the staff can understand the water flow situation of the installation pipe 1 when monitoring the liquid level, thereby improving the practicality of the device.

[0029] Further, such as Figure 1 As shown, a fixed base 20 is fixedly connected to the bottom of the installation pipe 1; two anti-skid pads 24 are connected to the fixed base 20. By providing the fixed base 20 and the anti-skid pads 24, when installing the device, the friction between the anti-skid pads 24 and the ground is increased through the anti-skid pads 24, thereby reducing the large-scale movement of the device during installation. The fixed base 20 improves the bearing capacity of the device, making the device more stable during installation.

[0030] Working principle: when working, by installing the installation pipe 1 on the urban drainage pipe, the water flow of the urban drainage pipe enters the interior of the wave-breaking tube 3 through the bottom of the wave-breaking tube 3 and the surface water inlet groove 21, and then uses the buoyancy of the floating block 6 and the floating slide bar 5 to make the floating slide bar 5 slide up and down in the sliding frame 4.

The floating slide bar 5 slides up and down to drive the rack 18 to move up and down, and the rack 18 drives the gear 19 to rotate. The gear 19 drives the gear 2 12 to rotate through the transmission rod, and drives the rack 18 to move up and down through the gear 2 12. By observing the scale plate on the rack 2 11 15, and then the liquid level height is obtained, which solves the problem that rain or dust enters the liquid level monitor outdoors, causing the liquid level monitor to be damaged, and the damaged monitor will not be able to provide data, delaying the timely collection of monitoring data, thereby improving the applicability of the device. When using the device, by transporting the installation pipe 1 to the installation position, and then aligning the external pipe and the installation pipe 1, the screw 183 is rotated by the handle 182, and the screw 183 drives the fixed clamping block 184 to move through the fixed block 181, so that the two fixed clamping blocks 184 are firmly clamped on the required external pipe, so that the shaking of the installation pipe 1 is reduced during installation. The movement of the protective shell 13 and the transparent observation plate 14 can be observed at any time through the transparent observation plate 14, which is conducive to observing the change of the liquid level. The protective shell 13 reduces the dust from entering the protective shell 13, and the long-term accumulation affects the operation of the internal components. The filter screen 22 and the water inlet trough 21 are provided, and the water inlet trough 21 assists the water flow to enter the wave-breaking tube 3, so that the water flow quickly enters the wave-breaking tube 3. The filter screen 22 reduces the amount of impurities or debris in the water that enter the wave-breaking tube 3, thereby affecting the monitoring of the liquid level. By providing a water flow monitor 19, when the device is used, it is possible to detect whether there is water flowing through the installation pipe 1 and the speed of the water flow, so that the staff can understand the water flow conditions of the installation pipe 1 when monitoring the liquid level, thereby improving the practicality of the device. By providing a fixed base 20 and an anti-skid pad 24, when installing the device, the friction between the anti-skid pad 24 and the ground is increased, thereby reducing the large-scale movement of the device during installation. The fixed base 20 increases the bearing capacity of the device, thereby making the device more stable during installation.
