Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water sump dredging, in particular to a water sump dredging equipment based on a dangerous area under a mine. BACKGROUND

[0002] In the operation and maintenance of coal mines and metal mine facilities, through the study of critical values, there are many dangerous areas in coal mines, and the water sump as a key sedimentation tank has long-term accumulated silt carried by the underground water. The composition of such silt is complex, so it is necessary to remove the silt underground to ensure normal drainage in the water sump and water channel.

[0003] When actually dredging the underground water channel, impurities are generally present in the underground silt, especially a large amount of long strip impurities with high winding and blocking properties, which leads to a high failure rate of the dredging equipment. The current mainstream equipment (such as centrifugal pumps, screw conveyors, and suction heads) will expose many problems when facing long strip impurities. Fibers, leftover belt sections, and hair mixed in the silt will cause the torque of the auger blade to increase sharply, and when the silt is sent into the suction pump through the auger blade, it will also cause the equipment to be blocked, resulting in poor continuity of the operation, uncontrolled maintenance costs, and serious constraints on the automation process of water sump dredging.

[0009] Preferably, the breaking mechanism comprises an arc surface carrier fixedly connected to the surface of the working vehicle body, an inclined block one is obliquely arranged on the surface of the arc surface carrier close to the side of the flexible curved surface sheet, a plurality of groups of soft hair needles are fixedly connected to the inclined block one along the length direction of the inclined block one close to the side of the flexible curved surface sheet, and an inclined block two is arranged inside the arc surface carrier close to the side of the soft hair needles.

[0010] Preferably, the carrier rod one and the carrier rod two rotate in opposite directions.

[0011] Preferably, the telescopic rod one intermittently contacts the curved surface of the trigger block in the working state, and drives the trigger block to rotate by a certain angle.

[0012] Preferably, the flexible curved surface sheet is in contact with the inclined block one through the carrier rod two in the working state.

[0013] Preferably, the flexible curved surface sheet generates a periodic motion in the working mode, and the inclined block two is axially knocked to disintegrate the sludge lumps and remove the flexible impurities attached to the surface of the flexible curved surface sheet.

[0014] Preferably, the flexible curved surface sheet is not in contact with the screw flight blades and the telescopic rod one.

[0015] Compared with the prior art, the present application has the following beneficial effects: (1) Through the setting of the stripping mechanism and the breaking mechanism, long strip-shaped impurities can be removed in time, when the flexible curved sheet is in a vertical ground posture, the accumulated thick silt layer can be effectively flattened, at the same time, the "L" shaped connecting structure composed of the rear group of flexible curved sheets and the second telescopic rod can effectively block (attach or entangle) the fiber impurities in the silt, while flattening the thick silt to optimize the collection efficiency of the auger blade, the most part of the fiber impurities is removed at the same time, thereby significantly reducing the risk of impurity entanglement, and providing more reliable protection for the auger blade; (2) Further, for the common U-shaped structure of the waterway bottom, the flexible curved sheet has excellent self-adaptive ability, can instantaneously fit the contour for effective displacement when contacting the waterway, when the second telescopic rod contacts the soft hair needle array, the active scraping of the fiber impurities is triggered immediately, at the same time, the second inclined block cooperates with the second telescopic rod: the rebound force generated after the second telescopic rod is compressed will drive it to knock the second inclined block, the impact force generated thereby can effectively shake off the long strip-shaped impurities and silt adhered to the surface, not only ensuring the smoothness of the current operation, but also realizing the self-cleaning of the key components, ensuring that the device always maintains high efficiency in continuous operation. (3) In order to solve the problem that the auger blade is difficult to fit the waterway bottom, causing difficulty in collecting thin silt, through the cooperation of the first telescopic rod and the swinging mechanism, the first telescopic rod intermittently drives the trigger block to work, through the operation of the working vehicle body, the thin silt layer on the waterway bottom is dynamically pushed to the center area to form a silt belt suitable for collection, effectively compensating for the gap between the auger blade and the U-shaped bottom, and significantly improving the conveying efficiency of the auger for thin silt layer.

[0016] (4) In order to cope with the risk of overload caused by sudden increase of silt, through the setting of the third spring and the push block, in the case of excessive silt, the push block automatically retreats under the action of silt pressure, releasing additional accommodation space, buffering the pressure of excessive silt on the auger blade, reducing the risk of jamming or locked-rotor of the auger blade due to overload, and ensuring the continuity of the dredging operation and the stability of the equipment operation.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments of the application. Based on the embodiments in the application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the application.

[0020] Please refer to Figures 1-10The application provides a technical scheme: a sump dredging device based on a dangerous area under a mine, which comprises a working vehicle body 100 and further comprises a driving mechanism 200, a guide mechanism 300, a stripping mechanism 400 and a swing mechanism 500.

[0021] During use, the auger blade 302 is not completely the same length as the carrier rod 301, and a mounting interval for the trigger component is reserved, the trigger component is fixedly connected on the carrier rod 301 at equal intervals, and a plurality of groups can be arranged around the axis of the carrier rod 301.

[0022] The working vehicle body 100 is internally provided with a silt suction pump, the silt suction pump is fixedly connected at an output end with a sewage conveying pipeline 101, the other end of the sewage conveying pipeline 101 is fixedly connected with the working vehicle body 100, and the auger blade 302 is used in cooperation to suck and treat the silt.

[0023] The trigger assembly comprises a telescopic rod 310 fixedly connected to the surface of the carrier rod 301, and the telescopic rod 310 is internally provided with a spring 2.

[0024] The swing mechanism 500 comprises a curved carrier 501 rotatably connected to the surface of the working vehicle body 100, a push block 502 fixedly connected to the end of the curved carrier 501 in the direction of the gravity center of the earth, a trigger block 503 fixedly connected to the surface of the curved carrier 501 on the side close to the push block 502, a curved surface on the surface of the trigger block 503, a carrier block 504 oppositely arranged on the side of the curved carrier 501 away from the trigger block 503, a spring 3 505 fixedly connected to the surface of each carrier block 504, a fixed block fixedly connected to the end of the spring 3 505, and the fixed block is fixedly connected with the working vehicle body 100.

[0025] It should be noted that in actual use, the push block 502 is made of flexible material, and under necessary conditions, a curved surface expansion limiting device or an equivalent limiting guiding device is installed inside the two spring threes 505. On the one hand, it is to avoid deformation of the spring three 505, and on the other hand, it plays a guiding role for the spring three 505, while avoiding the situation that the spring three 505 is stuck in the gap of the threaded state due to the stone in the silt, so that it cannot work. The material of the push block 502 is to adapt to most waterways, so the bottom surface of the channel is designed as a U shape to make the water flow better. Therefore, the push block 502 can better adapt to the work of treating silt underground. See Figures 5 to 8 The working vehicle body 100 is provided with a limiting roller near the curved surface carrier 501 according to its shape and movement state. The limiting roller is shown in the figure. The purpose is to enable the curved surface carrier 501 to work more smoothly.

[0026] The breaking mechanism 600 includes an arc surface carrier 601 fixedly connected to the surface of the working vehicle body 100. An inclined block one 602 is obliquely arranged on one side of the surface of the arc surface carrier 601 close to the flexible curved surface sheet 403. A plurality of groups of soft hair needles 603 are fixedly connected to the inclined block one 602 along the length direction of the inclined block one 602 close to one side of the flexible curved surface sheet 403. An inclined block two 604 is arranged inside the arc surface carrier 601 close to the soft hair needles 603.

[0027] During use, in the water channel of the water sump, when there is a lot of garbage in the silt, a collecting chamber can be arranged on the arc surface carrier 601 below the inclined block two 604, so that the garbage sliding down the surface of the inclined block two 604 can be uniformly collected. In a small number of cases, the garbage is intercepted by the blocking net at the water channel and water sump collection place. Then, after the water sump water is finished, the garbage is uniformly salvaged.

[0028] The load rod one 301 and the load rod two 401 rotate in opposite directions.

[0029] The telescopic rod one 310 is intermittently in contact with the surface of the trigger block 503 in the working state, and drives the trigger block 503 to rotate by a certain angle.

[0030] The flexible curved surface sheet 403 is in contact with the inclined block one 602 through the load rod two 401 in the working state.

[0031] The flexible curved surface sheet 403 generates periodic motion in the working mode, and strikes the inclined block two 604 in the axial direction, which is used to disintegrate the silt block and remove the flexible impurities attached to the surface of the flexible curved surface sheet 403.

[0032] The flexible curved surface sheet 403, the auger blade 302, and the telescopic rod one 310 do not contact each other. Working principle: When the silt blockage occurs at the water channel where the water sump is collected, the working vehicle body 100 is operated to enter the water channel before the water sump is collected, the driving mechanism 200 is driven towards the silt, the working vehicle body 100 starts to move, the driving mechanism 200 starts to work at this time, the stripping mechanism 400 first contacts the silt, the flexible curved sheet 403 starts to work under the driving of the second telescopic rod 402, the rotating direction of the second carrier rod 401 is the circumferential rotation direction towards the inclined block 602, the second telescopic rod 402 and the flexible curved sheet 403 contact the silt part and rotate into the silt, the long strip-shaped material with high entanglement and blockage in the silt is excavated, the long strip-shaped material is attached to the surface of the second telescopic rod 402 and the flexible curved sheet 403, the flexible curved sheet 403 is curved, when the flexible curved sheet 403 contacts, the flexible curved sheet 403 and the second telescopic rod 402 form a Z-shaped structure, the hair and fiber are attached to the Z-shaped structure, the Z-shaped structure is designed as a curved surface, which increases the contact probability and makes the attachment better, the intersection provides a winding point for the fiber, then the second telescopic rod 402 rotates towards the inclined block 602 inside the arc surface carrier 601, when the flexible curved sheet 403 contacts the large stone in the water channel or the U-shaped bottom surface of the water channel for better flow, the shape of the flexible curved sheet 403 actively avoids the large stone, the curved surface contact makes the avoidance more smooth, when the flexible curved sheet 403 first contacts the arc surface carrier 601, the flexible curved sheet 403 does not contact the arc surface carrier 601, but when it gradually approaches the inclined block 602, it moves towards the shaft of the second carrier rod 401, when it contacts the inclined block 602, the flexible curved sheet 403 is slowly retracted through the second telescopic rod 402, when it passes through the soft hair needle 603, the soft hair needle 603 scrapes the fiber and other long strip-shaped materials that are wound around the flexible curved sheet 403 and the second telescopic rod 402 close to the flexible curved sheet 403, when the flexible curved sheet 403 does not contact the inclined block 602, referring to Figure 5 , a gap is left between the inclined block 602 and the inclined block 604, at this time, the second telescopic rod 402 drives the flexible curved sheet 403 to hit the inclined block 604, referring to the principle of stamping feet, the inertia and impact force work together, the impact force causes the flexible curved sheet 403 to instantaneously deform and vibrate, this rapid deformation and vibration loosens the impurities and silt, so that the impurities leave the flexible curved sheet 403 and the second telescopic rod 402 and slide down the slope of the inclined block 604, at this time, the impurities can be processed in time or washed away by the water flow; In this case, the long strip impurities in the sludge have been basically removed, and the sludge moves towards the carrier bar one 301 direction along with the propulsion of the working vehicle body 100. When the carrier bar one 301 rotates, the carrier bar one 301 will drive the auger blade 302 and the telescopic rod one 310 to work, and the sludge moves towards the suction end of the sewage pipe 101. At the same time, with the rotation of the carrier bar one 301, the telescopic rod one 310 rotates towards the trigger block 503 direction. During the dredging process, some problems may occur, such as sludge over-penetration. The auger blade 302 in the prior art cannot completely adhere to the ground, and the waterway is mostly U-shaped. The telescopic rod one 310 will intermittently contact with the trigger block 503 during rotation. Referring to Figure 7 When contact occurs, the trigger block 503 will first drive the push block 502 to move towards the opposite direction of the working area. At this time, the working vehicle body 100 will move a certain distance. When the telescopic rod one 310 is not in contact with the trigger block 503, the push block 502 will move towards the sludge direction through the spring three 505, arching the sludge to increase the thickness of the sludge. When the sludge is sent into the suction end of the sewage pipe 101 by the auger blade 302, the sewage pipe 101 sucks the sludge into the working vehicle body 100 through the dredging pump. At this time, personnel can choose to clean up in time or store in the working vehicle body 100. After the dredging is completed, the sludge is taken out uniformly, and the above-mentioned dredging operation is completed.

[0033] The contents not described in detail in the description belong to the prior art known to those skilled in the art. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
