[0002] In the daily maintenance of sewage pipeline wells, it is necessary to detect the liquid level of the sewage inside the sewage pipeline wells. The water level is the most intuitive factor reflecting the water situation of the water body.
[0003] The existing sewage pipeline water level detection devices usually directly expose the liquid level sensor outside. Since there is a lot of garbage and many hard objects in the sewage pipeline, when the sewage flows, it will drive the garbage and other objects to collide with the liquid level sensor, which not only reduces the service life of the liquid level sensor, but also easily causes damage to the liquid level sensor, so that the water level in the pipeline cannot be detected in time. Therefore, we propose a sewage liquid level detection device in a sewage pipeline well. Content of the Utility Model

[0027] Please refer to Figures 1-6As shown in the figure, the utility model relates to a sewage level detection device in a sewage pipeline well, which includes a liquid level gauge 1. A mounting plate 11 is fixedly connected to the back of the liquid level gauge 1. A protective component 12 is arranged below the liquid level gauge 1. A circular bottom plate 111 is fixedly connected to the bottom of the liquid level gauge 1. The protective component 12 includes a protective cover 121. A baffle shell 122 is fixedly connected to the outer surface of the protective cover 121. A plurality of elastic clamping blocks 211 are arranged outside the circular bottom plate 111. The plurality of elastic clamping blocks 211 are arranged in a circumferential array with the circular bottom plate 111 as the center. A plurality of threaded blocks 212 are fixedly connected to the top of the protective cover 121. Nuts 213 are threadedly connected to the outer surfaces of the plurality of threaded blocks 212. By setting the protective component 12, specifically, the protective cover 121 is inserted into the bottom of the circular bottom plate 111, then the threaded blocks 212 will be inserted into the circular bottom plate 111, and then the nuts 213 are threadedly connected to the threaded blocks 212, so that the protective cover 121 can be installed and fixed. The protective cover 121 can protect the liquid level sensor 113, avoid the collision between garbage and the like and the liquid level sensor 113, improve the service life of the liquid level sensor 113, and at the same time avoid damaging the liquid level sensor 113. A fixed pipe 112 is fixedly connected to the center of the bottom of the liquid level gauge 1. Wires are arranged inside the fixed pipe 112. A plurality of liquid level sensors 113 are fixedly connected to the outer surface of the fixed pipe 112. Wires are arranged inside the fixed pipe 112 for transmitting electricity. The fixed pipe 112 plays a role in protecting the wires. A support seat 123 is arranged inside the baffle shell 122. A motor 124 is fixedly connected to the top of the support seat 123. A gear 125 is fixedly connected to the output end of the bottom of the motor 124. Two limiting rings 214 are fixedly connected to the outer surface of the protective cover 121. A rotating ring 13 rotates on the limiting rings 214. The limiting rings 214 play a role in supporting and limiting the rotating ring 13. A rotating ring 13 is arranged below the baffle shell 122. The inner ring of the rotating ring 13 contacts the outer surface of the protective cover 121. The top and bottom of the rotating ring 13 both contact the surfaces of the two limiting rings 214. A connecting frame 131 is fixedly connected to the bottom of the rotating ring 13. A scraping blade 132 is fixedly connected to the side of the connecting frame 131 close to the protective cover 121. A gear ring 133 is fixedly connected to the top of the rotating ring 13. The gear ring 133 is meshed with the gear 125. The side of the scraping blade 132 away from the connecting frame 131 contacts the surface of the protective cover 121. By setting the rotating ring 13, specifically, the motor 124 is started to drive the gear 125 to rotate, then the gear 125 drives the rotating ring 13 to rotate through the gear ring 133. When the rotating ring 13 rotates, it will drive the connecting frame 131 and the scraping blade 132 to rotate together, and then the scraping blade 132 will clean the surface and bottom of the protective cover 121, thereby avoiding the blockage of the notch, enabling the sewage to enter the protective cover 121 more smoothly, and improving the detection effect. A plurality of notches are opened on both the outer surface and the bottom of the protective cover 121. The bottom of the elastic clamping block 211 is fixedly connected to the surface of the protective cover 121. The top of the threaded block 212 penetrates through the circular bottom plate 111 and extends to the outside.The top of the protective cover 121 contacts the bottom of the circular base plate 111. The left side of the support base 123 is fixedly connected to the surface of the protective cover 121. One side of the elastic clamping block 211 close to the circular base plate 111 is triangularly arranged. When the elastic clamping block 211 contacts the bottom of the circular base plate 111, it will be pushed. When the top of the protective cover 121 contacts the bottom of the circular base plate 111, the elastic clamping block 211 will reset under the action of elasticity, thus supporting the protective cover 121 and facilitating subsequent installation.
[0028] A specific application of this embodiment is:
[0029] During use, insert the protective cover 121 into the bottom of the circular base plate 111, then the threaded block 212 will be inserted into the circular base plate 111. When the elastic clamping block 211 contacts the bottom of the circular base plate 111, it will be pushed. When the top of the protective cover 121 contacts the bottom of the circular base plate 111, the elastic clamping block 211 will reset under the action of elasticity, thus supporting the protective cover 121. Subsequently, thread the nut 213 onto the threaded block 212 to install and fix the protective cover 121. The protective cover 121 can protect the liquid level sensor 113, preventing garbage and the like from colliding with the liquid level sensor 113, increasing the service life of the liquid level sensor 113, and at the same time avoiding damaging the liquid level sensor 113. Since a number of notches are provided on the outer surface and the bottom of the protective cover 121, sewage can smoothly enter the interior of the protective cover 121 and be detected by the liquid level sensor 113. There is an electric wire inside the fixed pipe 112 for transmitting electricity, and the fixed pipe 112 protects the electric wire. The liquid level sensor 113 mainly works based on the principle of measuring liquid static pressure. When the liquid level sensor 113 is immersed in a certain depth of the measured liquid, the pressure received by the liquid level sensor 113 on the liquid-facing surface is proportional to the height of the liquid. The pressure of the liquid is introduced into the positive pressure chamber of the sensor through a stainless steel gas guide, and the atmospheric pressure on the liquid surface is connected to the negative pressure chamber of the sensor, thus offsetting the atmospheric pressure on the back of the sensor, making the pressure measured by the sensor proportional to the liquid level height. After the protective cover 121 is installed, install the liquid level gauge 1 in the sewage pipeline through the mounting plate 11. When there is a lot of garbage and sludge attached to the surface of the protective cover 121, start the motor 124 to drive the gear 125 to rotate. Then the gear 125 drives the rotating ring 13 to rotate through the gear ring 133. The rotating ring 13 rotates on the limiting ring 214. The limiting ring 214 is used to support and limit the rotating ring 13. When the rotating ring 13 rotates, it will drive the connecting frame 131 and the scraping blade 132 to rotate together. Then the scraping blade 132 will clean the surface and the bottom of the protective cover 121, thus preventing the notches from being blocked and enabling sewage to enter the protective cover 121 more smoothly, improving the detection effect.
