Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a pond bottom sludge clearing device. Background Art

[0002] Submersible sewage pumps are generally used to remove the sludge at the bottom of the sewage pool. The outlet of the submersible sewage pump is connected to the sludge collection area through a hose. When in use, the submersible sewage pump is sunk to the bottom of the pool through a lifting device (such as a traveling crane), and the sludge at the bottom of the pool is pumped out through a hose. The movement of the submersible sewage pump in the pool is achieved by the lifting device.

[0003] Because the bottom of the pool is uneven and there are stones or soil piles, the submersible sewage pump cannot avoid obstacles and is often stuck by stones or soil piles, causing the submersible sewage pump to fail to work normally. Utility Model Content

[0004] The utility model aims to provide a pond bottom mud clearing device to improve its obstacle crossing performance.

[0005] The technical solution of the utility model is: a pond bottom mud clearing device, including a submersible sewage pump, a buoy and a traveling frame, the submersible sewage pump is arranged in the traveling frame, the traveling frame and the buoy are connected by a retractable lifting mechanism, the lifting mechanism is provided with a gravity sensor, a sliding sleeve is fixed on the top of the traveling frame, a sliding rod is installed in the sliding sleeve, the sliding rod passes through the buoy and extends to the upper outside of the buoy, at least two of the pulling points are symmetrical on the buoy, and the traveling frame and the submersible sewage pump move with the buoy.

[0006] In the above scheme, the submersible sewage pump is sunk to the bottom of the pool by a retractable lifting mechanism. If the traveling frame encounters obstacles such as stones, earth piles, etc. at the bottom of the pool or pond during its movement, the traveling frame will generate a force exceeding its own gravity to tighten the lifting mechanism. At this time, the lifting mechanism starts and lifts the traveling frame. When the gravity sensor senses that the pulling force is lower than its own gravity, the lifting mechanism stops lifting, causing the traveling frame to fall with gravity. In this way, the gravity sensor sends a signal to control the action of the lifting mechanism, so that the submersible sewage pump can overcome obstacles and ensure its normal operation.

[0007] Preferably, the buoy is provided with at least two pulling points for swinging the buoy or moving the buoy horizontally by pulling and releasing, and at least two pulling points are symmetrical on the buoy. By adding a buoy, the movement of the submersible sewage pump in water can be achieved by pulling the pulling points on the buoy without using lifting equipment.

[0008] Preferably, the buoy is provided with at least two second lifting ears for hanging nylon ropes, and the second lifting ears form the pulling points.

[0009] Preferably, the lifting mechanism includes a winch and a steel wire rope wound around the winch, the steel wire rope is connected to a traveling frame, and the winch is installed on the buoy; the gravity sensor is arranged on the steel wire rope and close to the traveling frame.

[0010] Preferably, a plurality of first lifting ears are provided on the top of the submersible sewage pump, and the first lifting ears are connected to the traveling frame via a connecting piece.

[0011] Preferably, the connecting piece is a steel wire or a pipe clamp.

[0012] Preferably, a base is provided on the walking frame, and the submersible sewage pump is placed in the base.

[0013] Preferably, universal wheels are provided at the bottom of the walking frame.

[0014] Preferably, a patch plate is provided at the bottom of the walking frame.

[0015] Compared with the related art, the beneficial effects of the utility model are:

[0016] 1. Add a buoy and swing it by pulling and releasing it, so that the buoy, the traveling frame and the submersible sewage pump can be moved in any area of ​​the pool. The movement of the submersible sewage pump in the water can be achieved by pulling the pulling point on the buoy without using lifting equipment;

[0017] Second, the submersible sewage pump is sunk to the bottom of the pool through the retractable lifting mechanism. When the traveling frame encounters obstacles such as stones and earth piles at the bottom of the pool or pond during movement, the traveling frame will generate a force exceeding its own gravity to tighten the lifting mechanism. At this time, the lifting mechanism starts and lifts the traveling frame. When the gravity sensor senses that the pulling force is lower than its own gravity, the lifting mechanism stops lifting and makes the traveling frame fall with gravity. In this way, the gravity sensor sends a signal to control the lifting mechanism, so that the submersible sewage pump can overcome obstacles and ensure its normal operation.

[0018] 3. A sliding bar is provided on the traveling frame, which not only guides the lifting and lowering of the traveling frame, but also prevents the submersible sewage pump and the traveling frame from tipping over when being dragged;

[0019] Fourth, a universal wheel is arranged at the bottom of the traveling frame, and the universal wheel can reduce the friction resistance between the traveling frame and the sludge or the bottom of the pool, so as to better ensure the follow-up movement of the traveling frame, the submersible sewage pump and the buoy.

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0023] like Figure 1 As shown, a pond bottom mud clearing device provided in this embodiment includes a submersible sewage pump 1, a buoy 2, a traveling frame 3, a lifting mechanism 4, a universal wheel 5, a sliding sleeve 6, a sliding rod 7, a gravity sensor 8 and a connecting piece 9.

[0024] The submersible sewage pump 1 is an outsourced component, the bottom of which is mounted on the traveling frame 3 via a base 31 , and the top is provided with four first lifting ears 11 in a circular shape.

[0025] The buoy 2 can float on the water surface, and two or four second lifting ears 21 are symmetrically arranged on its circumference. Nylon ropes are installed on the second lifting ears 21. The buoy 2 is provided with two first through holes 22 for the slide bar 7 to pass through and one second through hole for the wire rope 42 to pass through.

[0026] The traveling frame 3 is a frame structure, which is welded by profiles such as stainless steel angle steel, channel steel or round steel. A universal wheel 5 is provided at the bottom. A base 31 is fixedly provided on the inner bottom surface of the traveling frame 3. Two third lifting ears 32 are provided on the top surface of the traveling frame 3. The first lifting ear 11 is connected to the corresponding position of the upper end of the traveling frame 3 through a connecting piece 9. The connecting piece 9 is a steel wire or a pipe clamp to prevent the submersible sewage pump 1 from rotating or finding relative displacement with the traveling frame 3 when working.

[0027] The lifting mechanism 4 includes a winch 41 and a steel wire rope 42 wound around the winch 41. The winch 41 is installed on the upper surface of the buoy 2, and the steel wire rope 42 passes through the second through hole and is connected to the third lifting lug 32 on the traveling frame 3. The winch 41 is retracted to lift or lower the steel wire rope 42, so that the traveling frame 3 and the submersible sewage pump 1 follow.

[0028] A sliding sleeve 6 is fixed on the top of the traveling frame 3, and a sliding rod 7 is installed in the sliding sleeve 6 by bolts. The sliding rod 7 passes through the first through hole 22 and extends to the upper outside of the buoy 2. The sliding rod 7 guides the up and down movement of the traveling frame 3. A patch plate 10 is provided at the bottom of the traveling frame 3. When the submersible sewage pump 1 is working, the patch plate 10 contacts with stones and soil piles, causing the traveling frame 3 to deviate, and the gravity sensor 8 senses the tension of the deflection. The patch plate 10 is located in the middle of the traveling frame 3.

[0029] The steel wire rope 42 is provided with a gravity sensor 8 , and the gravity sensor 8 is arranged close to the traveling frame 3 .

[0030] There are two slide bars 7, and the cable used by the submersible sewage pump 1 is arranged inside one slide bar 7, and the cable is fixed to the upper end of the slide bar 7 to prevent friction between the cable and the end of the slide bar 7. The cable between the control box of the winch 41 and the gravity sensor 8 is arranged inside the other slide bar 7.

[0031] When in use, a hose is connected to the outlet of the submersible sewage pump 1, and the other end of the hose is connected to the mud collection area beside the sewage pool. A nylon rope is installed on the second lifting lug 21. The nylon rope is then manually pulled to place the pool bottom mud clearing device in the corresponding position of the sewage pool. The power supply and the winch 41 are started, and the wire rope 42 is released to lower the walking frame 3 to the bottom of the pool. When the gravity sensor 8 has no gravity sensing signal output, the winch 41 is stopped. One pulling point corresponds to one operator. When one person pulls slowly, the other person slowly releases the rope, and vice versa, thereby forming a zigzag or bow-shaped back and forth pulling of the clearing device. In this way, 90% of the bottom mud within a range of 1-1.5 meters around the submersible sewage pump 1 can be extracted. When all the bottom mud in this range is extracted, the nylon rope is pulled horizontally to move the device to the next range, and the above steps are repeated until all the bottom mud is completely cleaned up.

[0032] When the patch plate 10 and / or the universal wheel 5 of the traveling frame 3 hit obstacles such as stones and earth piles at the bottom of the pool or pond, the traveling frame 3 will generate a force exceeding its own gravity to tighten the wire rope 42. At this time, the gravity sensor 8 on the wire rope 42 senses the force and sends a signal to the control box of the lifting mechanism 4, and the control box sends a command to the winch 41 to start it. The winch 41 releases the brake, rewinds the wire rope 42, and lifts the traveling frame 3. When the force sensed by the gravity sensor 8 is lower than the gravity of the traveling frame 3 itself, it sends a command to the stop winch 41 to stop the traveling frame 3 from lifting. At this time, the traveling frame 3 falls back to the bottom due to gravity. When the gravity sensor 8 outputs a weak sensing signal, the brake of the winch 41 is started, and the fixed wire rope 42 is closed again, thereby ensuring the successful obstacle crossing and normal operation of the dredging device.

[0033] When the bottom of the pool or pond is uneven, the universal wheel 5 can climb the slope, and the slide bar 7 can also be freely raised and lowered to achieve high self-adaptation. The maximum depth of the walking frame 3 descending depends on the length of the wire rope 42 adjusted when entering the water for the first time.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
