The protective component is located at the bottom of the wastewater data detector to push away the floccules and solids in the wastewater to prevent the presence of solids from affecting the detection position of the wastewater data detector. At the same time, the setting of the cable guide component prevents the wastewater data detector from excessively deviating from the detection point during the descent process, affecting the accuracy of the data and colliding with the adjacent wastewater data detectors, resulting in an increase in the number of damaged wastewater data detectors;

[0043] Furthermore, the length of the weighted cable is limited to adjust the depth of the descent of the wastewater data detector. The wastewater data detector is installed in coordination with the detector protective cover and the positioning frame 1. The positioning frame 1 is coordinated with the positioning frame 2. The flow-pushing block located on the surface of the positioning frame 2 realizes the rotation of the weighted cable with the threaded rotation of the threaded buckle and the limit plate, driving the counterweight frame and the flow-pushing block to rotate. Without affecting the balance of the detection position of the wastewater data detector, the water flow inside the wastewater pool is directly pushed. At the same time, through the intermittent setting of the threaded buckle and the gap between the threaded buckles, space is provided for the self-rotation and reset of the weighted cable, so that the weighted cable can realize forward and reverse reciprocating rotation under the drive of the threaded buckle, pushing the surrounding solid objects to all sides. Due to the rotation of the positioning frame 1 and the rotating rod, the rotation fluctuation is prevented from being transmitted to the wastewater data detector, so that the wastewater data detector maintains balance during the descent process, avoids the wastewater data detector from being bumped, reduces the data detection precision and accuracy of the wastewater data detector, and provides more reliable data support for wastewater treatment.

The closing frame 18 is set as a bucket-shaped frame structure, and the closing frame 18 penetrates the top of the support frame 17, and the center line of the closing frame 18 is aligned with the rotating rod 4;

[0078] The push plate 19 is installed on one side of the truncated cone hole inside the closing frame 18, and the push plate 19 is set to a petal-shaped structure, the inner wall surface of the push plate 19 abuts against the outer wall surface of the threaded buckle 24, and the push plate 19 and the engaging push ball 20 are both made of rubber material;

[0079] The engaging pushing ball 20 is installed on the other side of the truncated cone hole inside the closing frame 18, and the engaging pushing ball 20 is symmetrically arranged with the pushing plate 19;

[0080] The weight-increasing cable 21 has one end connected to the top of the rotating rod 4, and the weight-increasing cable 21 passes through the top of the closing frame 18, and the threaded buckle 24 on the outer wall of the weight-increasing cable 21 is rotatably connected to the threaded hole in the middle of the limiting plate 11;

[0081] The electric drive rotating frame 22 has a weight-added cable 21 wound around its surface, and the electric drive rotating frame 22 is composed of a work-shaped frame and a motor;

[0082] The threaded buckle 24 is snap-connected to the outer wall of the weight-increasing cable 21, and the threaded buckle 24 is configured as a C-shaped plate structure, and the outer wall of the threaded buckle 24 is configured as a threaded shape;

[0083] A connecting wire 25 is installed on the surface of the threaded buckle 24. One end of the connecting wire 25 is rotatably connected to the surface of the traction plate 23. The traction plate 23 is set as a plate structure, and the traction plate 23 is made of metal;

[0084] In conjunction with the accompanying drawings Figure 1-10 As shown, the support frame 17 is installed at the top of the limiting frame 13, and the closing frame 18 is installed by supporting the support frame 17. The pushing plate 19 set inside the closing frame 18 cooperates with the locking pushing ball 20, and the weight-increasing cable 21 entering the opening of the closing frame 18 is locked and connected with the threaded buckle 24, as shown in FIG. Figure 2-4 As shown, the threaded buckle 24 is tilted and guided by the pushing plate 19, so that the weight-added cable 21 is buckled on the outside, and the weight-added cable 21 is spherically limited by the engaging pushing ball 20 and pushed into the C-shaped structure of the threaded buckle 24, wherein the distance between the threaded buckles 24 is installed and adjusted according to the connecting line 25, and the connecting line 25 is adjusted and installed along with the traction plate 23, and the weight-added cable 21 is pushed down along with the push of the electric drive rotating frame 22, wherein the electric drive rotating frame 22 and the traction plate 23 adjust the installation position according to the shape of the wastewater tank, and when in use, the traction plate 23 pulls the threaded buckle 24 and the connecting line 25, and ... are installed. The moving frame 22 is driven by an electric weight-added cable 21 to hang the rotating rod 4 to adjust the wastewater detection depth. After the weight-added cable 21 is connected to the internal thread of the limit plate 11 through the threaded buckle 24, the positioning frame 2 5 is rotated to drive the flow block 9 to push the liquid to the periphery. When the threaded buckle 24 passes through the gap between the limit plate 11 and the next limit plate 11, the weight-added cable 21 is affected by the rotation and twisting of the previous threaded buckle 24 and rotates in the opposite direction to reset, thereby driving the positioning frame 2 5 to rotate in the opposite direction to drive the flow block 9 to push the liquid to the periphery, thereby preventing the liquid from directly colliding with the wastewater data detector 2.

[0085] Working principle: When using the wastewater pool detector with multi-point fixed depth, first the floating plate 14 drives the detector protective cover 1 and the internal wastewater data detector 2 to the wastewater pool detection position, and the electric drive rotating frame 22 is installed through the metal frame. Under the power drive, the weight-increasing cable 21 pushes the rotating rod 4 downward along the inside of the closing frame 18, and the threaded buckle 24 is arranged on the surface of the weight-increasing cable 21 to rotate and connect with the limit plate 11, thereby driving the weight-increasing cable 21 to rotate, and synchronously drives the positioning frame 2 5 and the flow-pushing block 9 at the bottom of the rotating rod 4 to rotate, so as to block the solid objects inside the wastewater pool encountered during the descent of the detector protective cover 1 and the wastewater data detector 2. Since the threaded buckle 24 is intermittently installed on the surface of the weight-increasing cable 21, the weight-increasing cable 21 after the threaded buckle 24 passes through the limit plate 11 is affected by the rotation and rotates, so that the positioning frame 2 5 and the flow-pushing block 9 at the bottom of the rotating rod 4 rotate in the opposite direction to drive the wastewater flow, pushing and separating. Nearby solid objects are realized to protect the wastewater data detector 2 during the descent process. The silicone ball 12 arranged on the side wall of the limit plate 11 cooperates with the limit frame 13 for limit installation to prevent the weight-added cable 21 from excessively bumping against the limit plate 11 during rotation. During the descent of the weight-added cable 21, the push plate 19 symmetrically arranged inside the closing frame 18 cooperates with the push ball 20 to engage and connect the weight-added cable 21 with the threaded buckle 24. The connecting line 25 located between the threaded buckles 24 is used to limit the installation distance. The connecting line 25 cooperates with the traction plate 23 to provide traction for the weight-added cable 21, and the auxiliary floating plate 14 floats on the surface of the wastewater pool. It is installed with one end of the connecting frame 16 through the positioning hole 15 at the upper end of the floating plate 14, and multiple floating plates 14 and the wastewater data detector 2 are connected through the connecting frame 16 for multi-point detection in the wastewater pool. At the same time, the electric drive rotating frame 22 is used to adjust the depth between each wastewater data detector 2 to increase the amount of detection data.
