The water outlet pipe 7 is located below the water inlet pipe 3, so that there is a height difference between the water outlet pipe 7 and the water inlet pipe 3, which is convenient for discharging filtered water.

[0045] A shunt pipe 4 is fixedly connected to the inside of the filter box 2, one end of the shunt pipe 4 is connected to the water inlet pipe 3, and the other end of the shunt pipe 4 is a closed end. In this embodiment, the closed end of the shunt pipe 4 is fixed to the side wall of the filter box 2 by welding, threaded connection or other methods, which are not specifically limited here. The end of the shunt pipe 4 connected to the water inlet pipe 3 is in the shape of a flared cone.

[0046] The shunt pipe 4 is connected with a plurality of fixing boxes 5 along its axial direction. The bottom of the fixing box 5 is located above the bottom of the filter box 2, so that there is a distance between the fixing box 5 and the bottom of the filter box 2, which is convenient for discharging the debris in the fixing box 5. The shunt pipe 4 is provided with a plurality of shunt holes, which are respectively connected with the plurality of fixing boxes 5. Figure 3 As shown, a filter screen is connected to the fixed box 5, and the filter screen is located at the lower part of the fixed box 5. A filter water pipe connected to the cavity below the filter screen is provided on the fixed box 5. In this embodiment, the bottom wall of the fixed box 5 is arranged in a wedge shape, and the bottom wall of the fixed box 5 is inclined toward the filter water pipe, so that the filtered water can be discharged from the filter water pipe to the greatest extent, reducing the residual water in the fixed box 5.

[0047] In this embodiment, one side of the fixed box 5 is an open end, and the open end of the fixed box 5 is detachably mounted with a plywood 6. In this embodiment, a seal 86 is connected to the side of the plywood 6 facing the fixed box 5. In this embodiment, the seal 86 is bonded and fixed to the plywood 6. A sealing groove matching the shape of the seal 86 is provided on the side of the fixed box 5 facing the plywood 6. When the plywood 6 closes the fixed box 5, the seal 86 is located in the sealing groove for sealing, that is, when the plywood 6 abuts against the open end of the fixed box 5, the fixed box 5 is sealed by the seal 86, thereby improving the sealing of the connection between the plywood 6 and the fixed box 5. By moving the plywood 6, the plywood 6 is moved away from or close to the open end of the fixed box 5, thereby realizing the opening or closing of the fixed box 5.

[0049] In this embodiment, the push plate 87 and the clamping plate 6 are fixedly connected with the control rod 84, and the control rod 84 and the fixed box 5 are horizontally slidably matched, that is, the control rod 84 passes through the through holes on the push plate 87 and the clamping plate 6 and is fixed by welding, bonding, etc., and the clearance between the control rod 84 and the through holes on the fixed box 5 is matched, so that the control rod 84 can move in the through hole of the fixed box 5. The output end of the telescopic drive unit 8 is connected to one end of the control rod 84. In this embodiment, when the clamping plate 6 is connected to the fixed box 5 and the fixed box 5 is in a closed state, the push plate 87 is close to the closed end of the fixed box 5 (i.e., the side away from the open end of the fixed box 5), so that when the clamping plate 6 is away from the fixed box 5, the push plate 87 can push out the debris in the fixed box 5. In this embodiment, by setting the control rod 84, the push plate 87 and the clamping plate 6 can be controlled to move, so that the clamping plate 6 moves away from the fixed box 5 and the debris in the fixed box 5 can be pushed out, so as to achieve the purpose of cleaning the debris filtered inside the fixed box 5.

[0050] In this embodiment, arc grooves matching the shape of the shunt tube 4 are provided on the tops of the fixing box 5 and the clamping plate 6. The shunt tube 4 is located in the arc groove and is welded or bonded to the arc groove on the top of the fixing box 5. The shunt tube 4 is gap-fitted with the arc groove on the top of the clamping plate 6, so that the clamping plate 6 can move axially along the shunt tube 4.

[0051] The telescopic drive unit 8 in this embodiment is a telescopic rod. Specifically, in this embodiment, the telescopic drive unit 8 is an electric telescopic rod 82. Figure 1 and Figure 2 As shown, in this embodiment, a mounting block 81 is connected to the outer side of the filter box 2, and the mounting block 81 is connected to the outer side of the filter box 2 by screws or welding. The fixed part of the electric telescopic rod 82 is installed on the mounting block 81, and the output end of the electric telescopic rod 82 extends into the interior of the filter box 2 and is coaxially connected to the control rod 84, and the output end of the electric telescopic rod 82 is slidably matched with the side wall of the filter box 2, that is, the output end of the electric telescopic rod 82 can telescopically move along the side wall of the filter box 2, and the electric telescopic rod 82 is threadedly connected or pinned or connected in other ways to the control rod 84, which belongs to the prior art and will not be repeated here.

[0052] The specific implementation process is as follows:

[0053] When it is necessary to use a filtering device for circulating water inside a foundation pit in the present invention, firstly, the filtering device for circulating water inside the foundation pit is moved to the position where it is needed by using a mobile trolley 1, and then the water inlet pipe 3 is connected to the foundation pit drainage pipe, so that the water to be filtered can enter the fixed box 5 inside the filter box 2 through the water inlet pipe 3 and the diversion pipe 4, and after the water to be filtered passes through the filter net in the fixed box 5, it flows out to the filter box 2 through the filter water pipe on the fixed box 5, and finally is discharged through the outlet pipe 7 for use.

[0054] When it is necessary to take out the debris inside the fixed box 5, the electric telescopic rod 82 on the mounting block 81 is started to extend the output end of the electric telescopic rod 82 so that the control rod 84 drives the push plate 87 and the closing plate 6 to move away from the fixed box 5. The closing plate 6 moves away from the fixed box 5, and the fixed box 5 is in an open state. During this process, the push plate 87 can push out the debris inside the fixed box 5, thereby achieving the purpose of cleaning the debris inside the fixed box 5.

[0055] Example 2

[0056] The difference between this embodiment and embodiment 1 is that: Figure 1 , Figure 2 and Figure 4 As shown, the inner bottom wall of the filter box 2 is provided with a first slide groove horizontally arranged with the control rod 84, a shift plate 83 is connected to one side of the control rod 84, and a first slider 85 is connected to the bottom of the shift plate 83. The first slider 85 is connected to the bottom of the shift plate 83 by welding, threaded connection, or screw connection, and the first slider 85 slides in cooperation with the first slide groove.

[0057] In this embodiment, the inner bottom wall of the filter box 2 is provided with a second chute, and the first chute and the second chute are respectively arranged near the two sides of the filter box 2, and the end of the control rod 84 away from the moving plate 83 is connected to the stabilizing plate 88, and the bottom of the stabilizing plate 88 is connected to the second slider 89, and the second slider 89 is connected to the bottom of the stabilizing plate 88 by welding, threading, screwing, etc., and the second slider 89 is slidably matched with the second chute. In this embodiment, the upper parts of the moving plate 83 and the stabilizing plate 88 are both welded, bonded, threaded, or connected in other fixing ways to the control rod 84, and the output end of the electric telescopic rod 82 is welded, threaded, or fixedly connected to the upper part of the moving plate 83, thereby realizing the connection with the control rod 84.

[0058] In this embodiment, under the action of the shift plate 83 and the stabilizing plate 88, the stability and alignment of the control rod 84 during movement can be guaranteed, the certainty and accuracy of the moving positions of the clamping plate 6 and the push plate 87 can be improved, and the matching accuracy between the push plate 87, the clamping plate 6 and the fixed box 5 can be improved.

[0059] Example 3

[0060] The difference between this embodiment and embodiment 2 is that: Figure 1 As shown, in this embodiment, a collecting unit 9 is provided at the bottom of the filter box 2. The collecting unit 9 is located directly below the plurality of fixing boxes 5. Figure 5As shown, the collection unit 9 in this embodiment includes a first collection box 91 and a second collection box 93. The first collection box 91 and the second collection box 93 are slidably matched along the axial direction of the control rod 84. By setting the first collection box 91 and the second collection box 93, the cleaned debris can be collected, thereby facilitating the disposal of the debris.

[0061] In this embodiment, a connecting plate 92 is provided between the second collection box 93 and the first collection box 91. Specifically, one end of the connecting plate 92 is connected to the second collection box 93, and the other end of the connecting plate 92 is slidably matched with the first collection box 91 along the axial direction of the control rod 84. In this embodiment, one end of the connecting plate 92 is fixed to the second collection box 93 by welding or screws. A sliding groove for accommodating the connecting plate 92 is provided in the first collection box 91. The end of the connecting plate 92 away from the second collection box 93 is inserted into the sliding groove of the first collection box 91 and slidably matched with the sliding groove, thereby realizing a sliding matching relationship between the first collection box 91 and the second collection box 93. In this way, the area for collecting debris formed between the first collection box 91 and the second collection box 93 can be expanded or reduced by sliding the second collection box 93. By providing the connecting plate 92, the first collection box 91 and the second collection box 93 can be connected, so that the second collection box 93 can move closer to or away from the first collection box 91 while ensuring the connection between the two, thereby facilitating the collection of debris cleaned from the fixed box 5.

[0062] In this embodiment, the stabilizing plate 88 is connected to the second collecting box 93. Specifically: Figure 1 and Figure 5 As shown, a first curved plate 94 is fixedly connected to one side of the second collecting box 93 close to the water outlet pipe 7, the first curved plate 94 is welded or screwed to one end of the second collecting box 93, a second curved plate 95 is welded or screwed to the lower part of the stabilizing plate 88, threaded holes are provided on the first curved plate 94 and the second curved plate 95, a connecting screw 96 is inserted between the threaded holes of the first curved plate 94 and the threaded holes of the second curved plate 95, and the first curved plate 94 and the second curved plate 95 are connected via the connecting screw 96.

[0063] By setting the connecting screw 96, the first arc plate 94 and the second arc plate 95 can be connected. By setting the first arc plate 94, the second arc plate 95 and the connecting screw 96, the movement of the second collecting box 93 can be automatically controlled by the movement of the stabilizing plate 88. When the stabilizing plate 88 moves and drives the closing plate 6 to open the fixing box 5, the stabilizing plate 88 will drive the second collecting box 93 to move away from the first collecting box 91. At this time, the connecting plate 92 slides in the first collecting box 91, thereby expanding the collection area of ​​the entire collecting unit 9, so that the debris cleaned out of the fixing box 5 can be collected to prevent the debris from falling into the filter box 2, which makes it inconvenient to clean the filter box 2.

[0064] Working principle: when it is necessary to use the filtering device for circulating water inside the foundation pit, first move the filtering device for circulating water inside the foundation pit to the position where it is needed by moving the trolley 1, and then connect the water inlet pipe 3 to the drainage pipe in the foundation pit, so that the water to be filtered can enter the fixed box 5 inside the filter box 2 through the water inlet pipe 3 and the diversion pipe 4 for filtration. After the water to be filtered is discharged into the filter box 2 through the filter water pipe on the fixed box 5, it is discharged through the water outlet pipe 7.

[0065] When it is necessary to take out the debris inside the fixed box 5, the electric telescopic rod 82 on the mounting block 81 is started, which drives the shifting plate 83 to make the first slider 85 slide on the surface of the first slide groove on the filter box 2. At the same time, the push plate 87 and the closing plate 6 are driven by the control rod 84 to move away from the fixed box 5. At this time, the push plate 87 pushes out the debris in the fixed box 5, thereby completing the cleaning of the fixed box 5. During the movement of the control rod 84, the stabilizing plate 88 fixedly connected to the control rod 84 is also driven to slide along the surface of the second slide groove on the filter box 2 under the action of the second slider 89. In the present invention, by providing a seal 86, the sealing performance of the connection between the clamping plate 6 and the fixed box 5 can be improved. By providing a push plate 87 and a control rod 84, when it is necessary to remove the large particles of debris filtered out between the fixed box 5 and the clamping plate 6, the clamping plate 6 can be controlled to move away from the fixed box 5. At the same time, the push plate 87 pushes the large particles of debris to move away from the fixed box 5 and drop onto the collecting unit 9, thereby completing the cleaning of the large particles of debris, avoiding the obstruction of the shunt pipe 4 during the process of removing the large particles of debris, and facilitating the cleaning of the debris.

[0066] When it is necessary to remove the large particles of debris on the collecting unit 9, first move the first collecting box 91, the connecting plate 92 and the second collecting box 93 to the inside of the filter box 2, adjust the position of the second collecting box 93, so that the first curved plate 94 moves close to the second curved plate 95, and rotate the connecting screw 96 to connect the two, so that when the stabilizing plate 88 moves, the first curved plate 94 can be driven to move by the second curved plate 95, thereby improving the effect of the second collecting box 93 and the first collecting box 91 in collecting debris. By setting the collecting unit 9, large particles of debris can be collected in the process of taking out large particles of debris, and large particles of debris can be avoided from falling into the filter box 2 as much as possible, thereby avoiding the situation where the filter box 2 is cleaned due to large particles of debris falling into the filter box 2 as much as possible.
