[0031] Embodiment 1:

[0032] As shown in Figures 1-3 A filter device for open-pit mine ditch, comprising a drainage ditch 4, a top frame 1 is arranged inside the drainage ditch 4, an adjusting column 2 is connected to the left and right ends of the top frame 1 through a limiting rod 8, a friction pad 5 is arranged on the outer wall of the adjusting column 2, the friction pad 5 is in contact with the inner wall of the drainage ditch 4, a filter screen 3 is connected inside the adjusting column 2 through a connecting rod 12, a gear 6 is fixedly connected to the rear end of the adjusting column 2, and the rear end of the gear 6 is rotatably connected to the front end of the top frame 1.

[0033] Specifically, after the limiting rod 8 is separated from the limiting groove, the angle of the adjusting column 2 can be adjusted. After the angle of the adjusting column 2 is adjusted, the limiting rod 8 is released, and the elastic potential energy of the compressed spring 9 is released, pushing the pressing plate 7 to move towards the initial position inside the top frame 1. Since the pressing plate 7 is fixedly connected to the limiting rod 8, the movement of the pressing plate 7 drives the limiting rod 8 to move together, so that the limiting rod 8 passes through the tooth gap of the gear 6 and reinserts into the limiting groove of the adjusting column 2, so that the rotation path of the gear 6 is blocked, thereby fixing the angle of the adjusting column 2. Moreover, the friction pad 5 installed at the bottom of the adjusting column 2 will be in direct contact with the inner wall of the drainage ditch 4 during this process, and the large friction of the friction pad 5 effectively increases the stability of the device in the drainage ditch 4, avoiding the impact force caused by the large water flow from causing the device to deviate. At the same time, the filter screen 3 installed on the adjusting column 2 has a certain elasticity and can be stretched according to the adjustment degree of the adjusting column 2, so as to ensure that the device will not have the problem of incomplete filtration after being installed in the drainage ditch 4.

[0034] As shown in Figure 7As shown, the top frame 1 is provided with a limiting rod 8 inside, and a pressure plate 7 is fixedly connected to the outer wall of the limiting rod 8. The top frame 1 is provided with a cavity, and the pressure plate 7 is slidably connected in the cavity. The rear end of the pressure plate 7 is connected to the inner wall of the cavity through a spring 9. The rear end of the adjusting column 2 is provided with a limiting groove, the front end of the limiting rod 8 is provided inside the limiting groove, and the rear end of the limiting rod 8 is provided with a pull ring.

[0035] Specifically, by applying a pulling force through the pull ring on the limiting rod 8, the limiting rod 8 is driven to slide along a preset track inside the top frame 1. During this process, the limiting rod 8 gradually disengages from the limiting groove on the adjusting column 2 and the teeth of the gear 6. At the same time, the pressure plate 7 tightly connected to the limiting rod 8 exerts a squeezing effect on the spring 9 connected to it as the limiting rod 8 moves, causing the spring 9 to undergo elastic deformation and store elastic potential energy. When the limiting rod 8 is completely disengaged, we can manually rotate the adjusting column 2 according to the actual shape inside the drainage ditch 4 to change its relative angle with the top frame 1, thereby achieving the purpose of adapting to different shapes of the drainage ditch 4.

[0036] Example 2:

[0037] As one of the optimized structural designs for Example 1, such as Figures 4-6 As shown, the filter screen 3 is fixedly connected to the connecting rod 12, the rear end of the connecting rod 12 is fixedly connected to the baffle 11, the outer wall of the adjusting column 2 is rotatably connected to the clamping plate 10, the surface of the clamping plate 10 is provided with a clamping groove, the connecting rod 12 is set inside the clamping groove, the surface of the adjusting column 2 is provided with a slot, and the size of the baffle 11 is adapted to the inner wall of the slot.

[0038] Specifically, by manually moving the locking plate 10 on the adjusting column 2, the locking plate 10 rotates around its connecting shaft with the adjusting column 2, thus revealing the slot on the adjusting column 2 that was originally covered by the locking plate 10. Next, we pick up the filter screen 3, align the baffle 11 on the filter screen 3 with the slot, and completely pass the baffle 11 through the slot. After the baffle 11 of the filter screen 3 has completely passed through the slot, we press the filter screen 3 tightly against the adjusting column 2. At this point, we release the locking plate 10 again, and the locking plate 10 quickly returns to its initial position under its own weight. The connecting rod 12 on the locking plate 10 then enters the corresponding snap-fit ​​groove on the filter screen 3. Through this snap-fit ​​method, the filter screen 3 is firmly installed on the adjusting column 2, thereby effectively filtering the water flow in the drainage ditch 4, intercepting various debris in the water flow, and ensuring the normal operation of the drainage system.

[0039] Working principle: first, by pulling the pull ring on the limiting rod 8, drive limiting rod 8 in the inside of the top frame 1 to move, so that the limiting rod 8 from the adjusting column 2 on the limiting slot and gear 6 between the teeth out, at the same time, the limiting rod 8 on the pressing plate 7 will be extruded on the spring 9 connected to it to change shape, so as to be able to adjust the angle of the adjusting column 2 connected to the top frame 1, in order to adapt to the different drainage ditch 4 inner wall slope, will adjust the adjusting column 2 after loosening the pull ring, under the action of the spring 9 will push the pressing plate 7 in the inside of the top frame 1 to move, thus driving the limiting rod 8 into the limiting slot to fix the adjusting column 2, and the friction pad 5 on the adjusting column 2 will be in direct contact with the inside of the drainage ditch 4, thus increasing the device in the drainage ditch 4 in the friction to avoid water flow too large and cause it to deviate, will install the device to the drainage ditch 4, then by turning the adjusting column 2 on the card plate 10, so that the installation groove on it is exposed, the baffle 11 on the filter screen 3 from the installation groove inside, the filter screen 3 close to the adjusting column 2, by loosening the card plate 10 so that the connecting rod 12 into the clamping groove on it, and then install the filter screen 3 to the adjusting column 2, so as to filter the water flow in the drainage ditch 4.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
