[0068] In addition, a third lubricating ring 121 is embedded in the rail groove 120 of the lower fixed rail 100a, the lower slider 320a extends into the rail groove 120 and fits against the inner wall of the third lubricating ring 121, and the lower end surface of the connecting shaft 330 fits against the upper end surface of the third lubricating ring 121.

[0069] The operating principle of the present invention is as follows:

[0070] like Figures 1 to 5 As shown, after the leachate flows into the leachate tank body 1, the entrained matter in the leachate will settle into the mud outlet trough 11 and fall into the cover body 30 through the opening of the baffle cover. When the sediment reaches a certain volume, the second drive motor 42 is started to drive the connecting disk 33 and the second sleeve 32 to rotate synchronously, that is, the cover body 30 is also driven to rotate synchronously, and the precipitated entrained matter is poured out from the opening position of the cover body. At the same time, it is necessary to start the first drive motor 41, and the first spiral blade 431 and the second spiral blade 431 push the sediment to move to the discharge port at the lower end of the mud outlet trough 11. Since the discharge port of the mud outlet trough 11 is in the middle position, the spiral directions of the two spiral blades are set in opposite directions. When rotating, the two spiral blades can achieve the purpose of gathering the precipitated entrained matter to the center, so as to quickly discharge the sediment and restore the liquid storage volume of the leachate tank body 1, thereby preventing the leachate from overflowing before reaching the liquid storage volume of the leachate tank body 1. On the one hand, it can protect the environment, and on the other hand, it can ensure the normal operation of the leachate tank body 1 and avoid safety hazards in use.

[0071] It should be noted that, as shown in Figure 2 and Figure 3 The first sealing ring 61, the second sealing ring 62 and the boss 403 are arranged to prevent seepage from the gap at the mounting position, and can play a good sealing effect; the lubricating ring 7 is connected with the connecting cone section 71, which can play a lubricating role during rotation, reduce the rotating wear of the first sleeve 31 and the second sleeve 32, prolong the service life, and reduce the maintenance cost.

[0072] Finally, as shown in Figure 1 and Figure 4 The power motor drives the rotating shaft 81 to rotate, and a cavity is formed between the adjacent two partitions. With the rotation of the rotating shaft 81, the entrained material discharged from the mud discharge chute 11 is discharged in batches and in order, which ensures the efficiency of the discharge and facilitates the orderly collection of the discharged material at the discharge port position of the box body 8.

[0073] The power motor, the first drive motor 41 and the second drive motor 42 are connected with the PLC controller for automatic and intelligent operation management, which can greatly reduce the working intensity. Since the PLC controller only involves use control and does not involve program setting, and the PLC controller is a commonly used device, the specific connection and setting of the PLC controller will not be described here.

[0074] As shown in Figure 1 , Figures 6 to 16 When the seepage liquid surface rises to the position of the discharge port of the seepage tank, the seepage liquid and the floating material move to the discharge port together. Since the floating material is accumulated, in order to avoid the accumulation affecting the discharge of the seepage liquid and causing the seepage liquid in the seepage tank to overflow from the upper opening of the seepage tank, the floating material needs to be scattered.

[0075] Specifically, as shown in Figure 6 , Figure 7 , Figures 13 to 15 The drive motor 232 is started on the PLC controller, driving the support block 233 to move along the axial direction of the guide rod 235, and the first Y-axis moving rail 220 and the second Y-axis moving rail 240 connected therewith also move synchronously. Since six first left inclined guide rails 211a and six first right inclined guide rails 212a are arranged on the first Y-axis moving rail 220, six angles α1 are formed between the first left inclined guide rails 211a and the X-axis of the first Y-axis moving rail 220, and the values of the adjacent two angles α1 gradually increase from left to right in equal difference; six angles β1 are formed between the first right inclined guide rails 212a and the X-axis of the first Y-axis moving rail 220, and the values of the adjacent two angles β1 gradually increase from right to left in equal difference.

[0076] Similarly, six second left-side inclined guide rails 214a and six second right-side inclined guide rails 215a are correspondingly provided on the second Y-axis movable rail 240. Six angles α2 are formed between the six second left-side inclined guide rails 214a and the X-axis line of the first Y-axis movable rail 220, and the values ​​of two adjacent angles α2 are set to be arithmetic and gradually increase from left to right. Six angles β2 are formed between the six second right-side inclined guide rails 215a and the X-axis line of the first Y-axis movable rail 220, and the values ​​of two adjacent angles β2 are set to be arithmetic and gradually increase from right to left. At the same time, a first Y-axis guide rail 213 coaxially arranged with the axis of symmetry L1 is also provided on the first Y-axis movable rail 220, and a second Y-axis guide rail 216 located directly below the first Y-axis guide rail 213 is also provided on the second Y-axis movable rail 240.

[0077] like Figure 6 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 15 and Figure 16 As shown, a connecting shaft 330 is provided between the guide rails at corresponding positions on the first Y-axis movable rail 220 and the second Y-axis movable rail 240. When the Y-axis movable rail makes linear motion along the Y-axis direction, the F generated by the connecting shaft 330 is Y+ To or F Y- The force in the direction of F X+ To or F X- The component force in the direction of the Y axis pushes the connecting shaft 330 to move linearly along the X axis, and enables the two side walls of the second side wing 322 to be stuck in the wide groove 312a of the first side wing 312 of the adjacent dredging block 310, forming a clamping action; at the same time, since the angle values ​​of the adjacent α1 and α2 and the angle values ​​of β1 and β2 are all set in equal intervals, the situation where each connecting shaft 330 is blocked due to the difference in moving distance is avoided, and the guide rails at corresponding positions are symmetrically arranged, ensuring the integrity and stability of the movement. As the drive motor 232 drives the two connected Y-axis moving rails to perform linear reciprocating motion along the Y axis, the first side wing 312 and the second side wing 322 set opposite to each other on the two adjacent connecting shafts 330 also perform reciprocating motion. The reciprocating clamping action generated by this can easily disperse the floating objects and prevent them from accumulating.

[0078] Among them, such as Figures 6 to 9As shown, during the movement of the Y-axis guide rail, the lower end face of the cover plate 34 is in contact with the upper end face of the first lubricating ring 217 embedded in the first Y-axis guide rail 213, the second lubricating ring 218 is embedded in the second left inclined guide rail 214a, the second right inclined guide rail 215a and the second Y-axis guide rail 216, the upper end groove wall of the ring groove on the connecting shaft 330 is in contact with the upper end face of the second lubricating ring 218, and the lower end groove wall of the ring groove is in contact with the lower end face of the second lubricating ring 218; the third lubricating ring 121 is embedded in the rail groove 120 of the lower guide rail 100a, the lower end face of the connecting shaft 330 is in contact with the upper end face of the third lubricating ring 121, the upper sliding block 320b extends into the fourth lubricating ring 219, and the outer wall of the upper sliding block 320b is in contact with the inner wall of the fourth lubricating ring 219, so that the stability of the connecting shaft 330 in the X direction is ensured, the moving wear is reduced, and the service life is prolonged.

[0079] It should be noted that the inner side wall of the fourth lubricating ring 219 and the inner side wall of the third lubricating ring 121 are both conical structures, and correspondingly, the outer side walls of the upper sliding block 320b and the lower sliding block 320a are also conical structures, so that the conical surfaces are more stable under the action of gravity, and the connecting shaft 330 is not easy to move.

[0080] During use, the water spray is positioned at the position of the flushing pipe 10, the block 310 is positioned at the position of the water spray, the floating residues are prevented, and when the liquid surface falls below the plane where the platform 12 is located, the driving motor 232 is closed; at the same time, when the liquid level of the seepage liquid continues to rise and the ultrasonic liquid level meter 102 detects that the liquid level is too high, a signal will be sent to the connected PLC controller, and the PLC controller sends a signal to the alarm device, so as to quickly and timely give an early warning to prevent the seepage liquid from overflowing.

[0081] The ultrasonic liquid level meter 102, the power motor, the driving motor 232, the first driving motor 41 and the second driving motor 42 are all connected to the PLC controller for automatic and intelligent operation management, which greatly reduces the working intensity. Since the PLC controller only involves use control and does not involve program setting, and the PLC controller is a commonly used device, the specific connection and setting of the PLC controller will not be described here.
