[0002] A drainage pressure relief device is an engineering facility widely used in bridges and other structures to reduce the pressure and deformation caused by moisture, which can cause corrosion, damage or instability in the bridge structure, thereby reducing the safety and life of the structure. The main purpose of the drainage pressure relief device is to ensure that the bridge structure remains dry. Through an effective drainage system, moisture is quickly directed outside the bridge, thereby reducing the impact of moisture on the bridge structure.

[0003] When the existing drainage pressure reducing device is used to drain the road bridge, the debris and garbage on the road bridge will enter the drainage device with the water flow. Too much garbage can easily cause the drainage device to be blocked, thereby reducing its drainage efficiency. In addition, after the debris and garbage on the road enters the drainage device, it is time-consuming and labor-intensive to collect and clean it, which is inconvenient for us to collect and clean it.

[0004] For this reason, we propose a drainage pressure reducing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides an embodiment: a drainage pressure reducing device, comprising a drainage box 1, a water inlet plate 2 is fixedly connected at the middle position of the upper surface of the drainage box 1, and a water inlet 3 is opened inside the drainage box 1 below the water inlet plate 2, a protective plate 4 is installed on the upper surface of the drainage box 1 on one side of the water inlet plate 2, and a mounting groove 5 is opened inside the drainage box 1 below the protective plate 4, and a water outlet 6 is opened on one side of the drainage box 1;

[0025] A cleaning device 7, which is arranged on the inner wall of the water inlet 3 below the water inlet plate 2, and is used to clean the garbage inside the water inlet 3;

[0026] A collecting device 8, which is arranged on the inner wall of the mounting groove 5, and is used to collect the garbage cleaned out by the cleaning device 7;

[0027] Furthermore, according to the example Figure 2 As shown, the bottom of the water inlet 3 is arranged to be inclined, and the inclination direction is toward the water outlet 6. The water inlet 3 and the water outlet 6 are connected inside the drainage box 1, so that water flow will not remain inside the water inlet 3, and the water flow inside the water inlet 3 can be discharged from the device more smoothly through the water outlet 6.

[0028] Furthermore, according to the example Figure 3 As shown, the cleaning device 7 includes a bidirectional motor 71, the output end of the bidirectional motor 71 is fixedly connected to a screw 72, and the outer surface of the screw 72 is threadedly connected to a push block 73, the upper surface of one end of the push block 73 is fixedly connected to an isolation plate 74, and the bottom of one side of the push block 73 is fixedly connected to a stop block 75, a filter plate 76 is arranged below the stop block 75, and the filter plate 76 is fixedly connected to the inner wall of the water inlet 3, and the size of the filter plate 76 is set to be the same as the size of the water inlet 3, so that when the water flows inside the water inlet 3, it must be filtered by the filter plate 76 before it can continue to flow downward, which to a certain extent avoids the problem of garbage and debris blocking the water outlet 6.

[0029] Furthermore, according to the example Figure 3 As shown, the length dimension of the isolation plate 74 is set to be greater than the length dimension of the push block 73, and the width dimension of the push block 73 and the isolation plate 74 is the same as the width dimension of the filter plate 76 and the water inlet 3, so that when the push block 73 drives the isolation plate 74 to push the garbage and debris on the upper surface of the filter plate 76, the isolation plate 74 can block the water flow above the water inlet 3, thereby preventing the push block 73 from pushing too much water into the interior of the collection box 81.

[0030] Furthermore, according to the example Figure 4 As shown, the collecting device 8 includes a collecting box 81, a telescopic rod 82 is fixedly connected to one side of the upper end of the collecting box 81, and a spring 83 is sleeved on the outer surface of the telescopic rod 82, the other end of the telescopic rod 82 is fixedly connected to a baffle 84, one end of the spring 83 is fixedly connected to one side of the inner wall of the collecting box 81, and the other end of the spring 83 is fixedly connected to one side of the baffle 84, and a closing door 85 is slidably connected to one side of the bottom of the collecting box 81, the bottom surface of the collecting box 81 is arranged in an inclined shape, and a slot is provided at one end of the bottom surface of the collecting box 81, and the bottom end of the closing door 85 is inserted into the inner wall of the slot provided on the bottom surface of the collecting box 81, so that when cleaning the garbage and debris inside the collecting box 81, the garbage and debris inside the collecting box 81 can slide down the slope for easier cleaning and collection.

[0031] Furthermore, according to the example Figure 2 and Figure 4As shown, sliding grooves are provided at the four ends of the inner wall of the installation groove 5, and sliding blocks are provided at the four ends of the outer surface of the collection box 81, and the sliding blocks provided on the outer surface of the collection box 81 are snap-fitted and slidably connected to the inner wall of the installation groove 5, so that when the collection box 81 is pulled to clean the garbage and debris inside the collection box 81, the collection box 81 will not be offset or tilted.

[0032] Working principle: When the drainage pressure reducing device is used for drainage, water flows through the water inlet plate 2 into the inner wall of the water inlet 3 opened inside the drainage box 1. When passing through the water inlet 3, the garbage and debris in the water flow are filtered by the filter plate 76 in the cleaning device 7. The garbage and debris filtered by the filter plate 76 stay on the upper surface of the filter plate 76. The water flows through the filter plate 76 into the inner wall of the water outlet 6 and is discharged from the drainage box 1 through the water outlet 6. When the garbage and debris on the upper surface of the filter plate 76 accumulate to a certain extent, the bidirectional motor 71 is started, so that the bidirectional motor 71 drives the screw 72 to rotate, and the push block 73 drives the isolation plate 74 and the stop block 75 to move through the thread, and the stop block 75 pushes the baffle 84 so that the baffle 84 pushes the telescopic rod 82 to retract, and the isolation plate 74 blocks the water inlet 3, so that the water cannot flow downward, and the push block 73 pushes the garbage and debris on the upper surface of the filter plate 76 into the interior of the collection box 81. After the push block 73 moves to the top of the screw 72, the bidirectional motor 71 starts to rotate in the opposite direction, so that the screw 72 drives the push block 73 to retract and move. In the process of the push block 73 driving the isolation plate 74 and the stop block 75 to retract and move, the spring 83 uses its own elasticity to make the baffle 84 fit the stop block 75 and move until the baffle 84 is restored, and the water in the water inlet 3 continues to flow. At this time, the garbage and debris on the upper surface of the filter plate 76 are cleaned up, and the drainage device can continue to drain.

[0033] When the garbage and debris inside the collection box 81 accumulate to a certain extent, the protective plate 4 is removed from the upper surface of the drainage box 1, and the collection box 81 is pulled to slide inside the installation groove 5. When the collection box 81 moves to the top of the inner wall slide groove of the installation groove 5, the closing door 85 is opened to clear the garbage and debris inside the collection box 81. After the inside of the collection box 81 is cleared, the closing door 85 is closed, the collection device 8 is slid to the bottom of the installation groove 5, and the protective plate 4 is installed on the upper surface of the installation groove 5. At this time, the collection device 8 is installed.
