[0001] The utility model relates to the technical field of sewage treatment, in particular to a water level early warning device for urban domestic sewage treatment plants. Background Technique

[0002] In the process of developing planting and livestock breeding industries in towns, the development of agriculture has been promoted, the living standards of residents have been improved, and at the same time, the urban water environment has been seriously polluted; it not only pollutes the living environment of residential areas, but also pollutes water bodies such as rivers and lakes in the region, affects the ecological environment, and even threatens the safety of drinking water quality.

[0003] After retrieval, the publication (announcement) number: CN220773722U discloses a river water level early warning device, which relates to the technical field of river water level early warning devices, including a bottom plate. The upper surface of the bottom plate is fixedly connected with a rectangular seat. The upper surface of the rectangular seat is fixedly connected with a hydraulic rod. One end of the hydraulic rod is fixedly connected with a rack. The outer surface of the rack is slidably connected with a limiting frame. The design structure of this utility model is reasonable. It can, through the cooperation between the bottom plate, the hydraulic rod, the first gear and the toothed plate, when the hydraulic rod is started, the hydraulic rod drives the first gear to rotate through the rack and the teeth, and the first gear drives the second gear to rotate, so that the toothed plate slides up and down in the limiting frame, changing the height of the early warning device, and solving the problem that the existing river water level early warning device is inconvenient to adjust the height of the river water level early warning device after installation, has a small application range, low practicability, and reduces the application range of water level detection and early warning.

[0004] Although the above solution solves the problem that the existing river water level early warning device is inconvenient to adjust the height of the river water level early warning device after installation, most water level early warning devices use a floating plate to judge the water level, and garbage or water plants in the sewage are easy to entangle the floating plate and affect its lifting, thus affecting the early warning accuracy of the water level early warning device. For this reason, we propose a water level early warning device for urban domestic sewage treatment plants. Content of the Utility Model

When the driving motor 204 drives the threaded shaft 201 to rotate, the moving member 202 can drive the U-shaped connecting rod 203 to move up and down along the threaded shaft 201;

[0030] As Figure 3 shown, the warning unit 3 includes an alarm 301 installed at one end of the U-shaped connecting rod 203 away from the moving member 202, a limit cylinder 302 installed at the bottom of the alarm 301, a first conduction sheet 303 installed at the bottom of the alarm 301 and located in the limit cylinder 302, and a warning member 304 arranged in the limit cylinder 302. When the warning member 304 is in conduction with the first conduction sheet 303, the alarm 301 can be triggered to issue an alarm.

[0031] As Figure 1 shown, the main body unit 1 includes a fixed seat 101, a mounting seat 102 installed on the side wall of the fixed seat 101, and a mounting hole 103 opened on the mounting seat 102. The setting of the mounting seat 102 facilitates the convenient movement of the entire device.

[0032] As Figure 3 shown, the adjustment unit 2 further includes a limit washer 205 installed on the inner side wall of the fixed seat 101, and the limit washer 205 is sleeved on the circumferential side of the threaded shaft 201. The setting of the limit washer 205 avoids the contact and collision between the moving member 202 and the inner side wall of the fixed seat 101 during the up and down movement of the moving member 202 along the threaded shaft 201.

[0033] As Figure 3As shown, the filter unit 4 includes a cylinder 401 installed at the bottom of the limiting cylinder 302 and filter holes 402 opened on the surface of the cylinder 401. The setting of the filter holes 402 facilitates the sewage to enter the limiting cylinder 302 through the cylinder 401.

[0034] like Figure 3 and Figure 5 As shown, the fixing seat 101, the mounting seat 102, the limiting cylinder 302, the warning member 304 and the cylinder 401 are all made of insulating, anti-corrosive and high-temperature resistant materials, which reduces the erosion of sewage on the early warning device.

When the driving motor 204 drives the threaded shaft 201 to rotate, the moving member 202 can drive the U-shaped connecting rod 203 to move up and down along the threaded shaft 201;

[0038] like Figure 3 As shown, the warning unit 3 includes an alarm 301 installed at one end of the U-shaped connecting rod 203 away from the moving part 202, a limiting cylinder 302 installed at the bottom of the alarm 301, a first conductive sheet 303 installed at the bottom of the alarm 301 and located in the limiting cylinder 302, and a warning member 304 arranged in the limiting cylinder 302. When the warning member 304 is connected to the first conductive sheet 303, the alarm 301 can be triggered to sound an alarm.

[0039] like Figure 1As shown, the main body unit 1 includes a fixed seat 101, a mounting seat 102 installed on the side wall of the fixed seat 101, and a mounting hole 103 opened on the mounting seat 102. The setting of the mounting seat 102 facilitates the convenient movement of the entire device.

[0040] As Figure 3 shown, the adjusting unit 2 further includes a limit washer 205 installed on the inner side wall of the fixed seat 101, and the limit washer 205 is sleeved on the circumferential side of the threaded shaft 201. The setting of the limit washer 205 prevents the moving part 202 from coming into contact and collision with the inner side wall of the fixed seat 101 during the up and down movement along the threaded shaft 201.

When the floating plate 3043 moves upward under the buoyancy force, it can drive the second conduction sheet 3042 to move upward synchronously through the conduction rod 3041.

[0042] As Figure 3 shown, the filtering unit 4 includes a cylinder 401 installed at the bottom of the limit cylinder 302, and filter holes 402 opened on the surface of the cylinder 401. The setting of the filter holes 402 facilitates the sewage to enter the limit cylinder 302 through the cylinder 401.

[0043] As Figure 3 With Figure 5 shown, the materials of the fixed seat 101, the mounting seat 102, the limit cylinder 302, the warning part 304 and the cylinder 401 are all insulating, anti-corrosive and high-temperature resistant materials, which slow down the erosion of the sewage on the warning device.

[0044] When the water level rises, since the cylinder 401 is immersed in water, according to the principle of communicating vessels, water will enter the inside of the cylinder 401 through the filter holes 402 on the cylinder 401 until the water surface heights inside and outside the cylinder 401 are the same and then stop. During the rising process of the water level, the floating plate 3043 drives the second conduction sheet 3042 to move upward through the conduction rod 3041. When the second conduction sheet 3042 contacts the first conduction sheet 303, it is electrified, thereby triggering the alarm 301 to issue an alarm.
