[0002] In the field of sewage treatment, the sewage removal mechanism plays an important role. Generally, in the sewage pretreatment process, a sewage removal mechanism needs to be installed in a sewage pool. The sewage removal mechanism generally adopts a grid sewage removal machine. The grid sewage removal machine is used for intercepting and conveying sundries such as plastic garbage, branches and weeds, so as to ensure that the sewage in the sewage pool is preliminarily purified. Generally, the sewage removal mechanism cannot predict the amount of sundries in the sewage pool. The sewage removal mechanism can only convey and clean the sundries in the sewage pool outward according to a predetermined power. However, when the amount of sundries in the sewage pool is large, the sundries are accumulated at the front side of the lifting end of the sewage removal mechanism at the water inlet end of the sewage pool, so that the sewage cannot flow to the rear side of the lifting end, and the sewage removal mechanism cannot normally discharge the sundries, which causes the problem of sewage pool blockage, and seriously affects the efficiency of sewage treatment.

[0027] In order to make the technical scheme and beneficial effects of the present disclosure more comprehensible, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0028] As Figures 1 to 3As shown, the liquid level difference monitoring device 10 of an embodiment comprises a sewage pool 100, a decontamination mechanism 200, a first liquid level sensor 300, a second liquid level sensor 400, a data feedback system (not shown in the figure) and a stirring assembly 500. The decontamination mechanism 200 corresponds to the sewage pool 100, and the lifting end of the decontamination mechanism 200 extends into the sewage pool 100, which is used to lift the sundries in the sewage pool 100. The first liquid level sensor 300 and the second liquid level sensor 400 are both arranged in the sewage pool 100 and are sequentially arranged along the sewage flow direction of the sewage pool 100. Specifically, the sewage flow direction is from the front side of the lifting end to the rear side of the lifting end, that is, the sewage flow direction is from the side where the first liquid level sensor 300 is located to the side where the second liquid level sensor 400 is located. The lifting end is located between the first liquid level sensor 300 and the second liquid level sensor 400. The first liquid level sensor 300 is used to monitor the front side liquid level height 110 of the lifting end, and the second liquid level sensor 400 is used to monitor the rear side liquid level height 120 of the lifting end. The stirring blade 530 of the stirring assembly 500 rotates in the sewage pool 100 and is used to stir the sundries in the front side of the lifting end. The data feedback system is used for comparison and processing of the front side liquid level height 110 and the rear side liquid level height 120, and sends a front side blockage signal to the stirring assembly 500. According to the front side blockage signal, the power of the stirring assembly 500 is adjusted, so that the stirring assembly 500 speeds up the stirring of the accumulated sundries in the front side.

[0029] It can be understood that, since the first liquid level sensor 300 and the second liquid level sensor 400 are sequentially arranged along the sewage flow direction of the sewage pool 100, and the lifting end of the decontamination mechanism 200 is located between the first liquid level sensor 300 and the second liquid level sensor 400, the first liquid level sensor 300 can monitor the front side liquid level height 110 of the lifting end, and the second liquid level sensor 400 can monitor the rear side liquid level height 120 of the lifting end. When the front side liquid level height 110 is greater than the rear side liquid level height 120, and the difference between the two is greater than the preset blockage difference, that is, the value obtained by subtracting the rear side liquid level height 120 from the front side liquid level height 110 is greater than the preset blockage difference, the data feedback system sends a front side blockage signal to the stirring assembly 500, so as to ensure that the power of the stirring assembly 500 is adjusted in time to speed up the stirring and dispersion of the accumulated sundries in the front side, and ensure that the sundries in the front side can be discharged from the sewage pool 100 through the lifting end of the decontamination mechanism 200 in time, so as to avoid the blockage of the sewage pool 100, thereby improving the treatment efficiency of the sewage.

[0030] As shown in the figure, the liquid level difference monitoring device 10 of an embodiment comprises a sewage pool 100, a decontamination mechanism 200, a first liquid level sensor 300, a second liquid level sensor 400, a data feedback system (not shown in the figure) and a stirring assembly 500, the decontamination mechanism 200 corresponds to the sewage pool 100, and the lifting end of the decontamination mechanism 200 extends into the sewage pool 100, which is used to lift the sundries in the sewage pool 100. The first liquid level sensor 300 and the second liquid level sensor 400 are both arranged in the sewage pool 100 and are sequentially arranged along the sewage flow direction of the sewage pool 100. Specifically, the sewage flow direction is from the front side of the lifting end to the rear side of the lifting end, that is, the sewage flow direction is from the side where the first liquid level sensor 300 is located to the side where the second liquid level sensor 400 is located. The lifting end is located between the first liquid level sensor 300 and the second liquid level sensor 400. The first liquid level sensor 300 is used to monitor the front side liquid level height 110 of the lifting end, and the second liquid level sensor 400 is used to monitor the rear side liquid level height 120 of the lifting end. The stirring blade 530 of the stirring assembly 500 rotates in the sewage pool 100 and is used to stir the sundries in the front side of the lifting end. The data feedback system is used for comparison and processing of the front side liquid level height 110 and the rear side liquid level height 120, and sends a front side blockage signal to the stirring assembly 500. According to the front side blockage signal, the power of the stirring assembly 500 is adjusted, so that the stirring assembly 500 speeds up the stirring of the accumulated sundries in the front side. Figure 1As shown in the drawings, in one of the embodiments, the first liquid level sensor 300 is an ultrasonic liquid level sensor, and the second liquid level sensor 400 is an ultrasonic liquid level sensor. In the embodiment, the detection end of the ultrasonic liquid level sensor can not be directly contacted with the sewage, and the detection accuracy of the liquid level height of the sewage is higher, which ensures the accuracy of the first liquid level sensor 300 detecting the front side liquid level height 110 of the lifting end of the decontamination mechanism 200 and the second liquid level sensor 400 detecting the rear side liquid level height 120 of the lifting end of the decontamination mechanism 200, thereby improving the accuracy of monitoring the liquid level difference of the sewage.

[0031] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in one of the embodiments, the stirring assembly 500 includes a motor 510, a stirring rotating shaft 520, and stirring blades 530. The motor 510 is arranged outside the sewage tank 100, the stirring rotating shaft 520 is rotatably arranged in the mounting hole 101 of the sewage tank 100, and a part of the stirring rotating shaft 520 is located in the sewage tank 100. The driving end of the motor 510 is connected to one end of the stirring rotating shaft 520, the other end of the stirring rotating shaft 520 is connected to the stirring blades 530, and the stirring blades 530 are arranged towards the decontamination mechanism 200. In the embodiment, the motor 510 transmits power to the stirring rotating shaft 520, thereby driving the stirring blades 530 to rotate. Since the stirring blades 530 are arranged towards the decontamination mechanism 200, i.e., the stirring blades 530 are arranged towards the lifting end of the decontamination mechanism 200, and the stirring blades 530 are located at the front side of the lifting end, it is ensured that the stirring blades 530 can stir the sundries accumulated at the front side of the lifting end, so that the sundries at the front side can be lifted and discharged out of the sewage tank 100 in time, thereby avoiding the blockage of the sewage tank 100.

[0032] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in one of the embodiments, the stirring assembly 500 further includes a waterproof sealing ring 540, which is sleeved on the inner wall of the mounting hole 101, and the stirring rotating shaft 520 is rotatably arranged in the waterproof sealing ring 540. In the embodiment, since the stirring rotating shaft 520 is rotatably arranged in the mounting hole 101 of the sewage tank 100, the waterproof sealing ring 540 is additionally arranged, which can ensure that the stirring rotating shaft 520 can rotate in the waterproof sealing ring 540, and can prevent the sewage from leaking out of the gap between the mounting hole 101 and the stirring rotating shaft 520.

[0033] As shown in the drawings, Figure 1 and Figure 2As shown in the drawings, in one embodiment, the dirt removal mechanism 200 includes a dirt lifting body 210 and a dirt discharging machine 220, one end of the dirt lifting body 210 is located at the bottom of the sewage tank 100, the dirt lifting body 210 is formed with a lifting conveying channel 211, the dirt discharging machine 220 is arranged on the sewage tank 100, the other end of the dirt lifting body 210 is connected with the dirt discharging machine 220, the dirt discharging machine 220 is formed with a discharging channel 221, the lifting conveying channel 211 and the discharging channel 221 are communicated, the lifting conveying channel 211 is used for lifting the dirt, and the discharging channel 221 is used for discharging the dirt. In this embodiment, since the lifting conveying channel 211 of the dirt lifting body 210 is communicated with the discharging channel 221 of the dirt discharging machine 220, the dirt can be transported to the discharging channel 221 through the lifting conveying channel 211, so that the dirt can be discharged from the sewage tank 100 in time.

[0034] As shown in the drawings, Figure 1 In one embodiment, the liquid level difference monitoring device 10 further includes a deodorizing cover 600, which is arranged on the sewage tank 100 and covers the dirt discharging machine 220. In this embodiment, since the discharged dirt produces odor gas, the deodorizing cover 600 is arranged on the dirt discharging machine 220 to avoid the odor gas of the dirt from overflowing outward, thereby avoiding pollution of the external air.

[0035] Further, in one embodiment, the liquid level difference monitoring device 10 further includes an adsorption layer (not shown in the drawings), which is arranged on the inner wall of the deodorizing cover 600 and is used for adsorbing the odor gas emitted by the discharged dirt.
