Description

Technical Field

[0001] This utility model relates to the technical field of municipal pipe well conveying tools, and in particular to a precision conveying device for small-diameter municipal pipe well water plugging airbags. Background Technology

[0002] Municipal sewage pipe networks are a massive and systematic project. Municipal sewage pipe manholes are widely distributed throughout the city. Since these manholes are the main points of connection between the sewage pipe network and the outside world, most of the silt blockages occur at these manholes during long-term sewage discharge and drainage processes. The blockage of the municipal sewage pipe openings by silt directly affects the sewage discharge and drainage functions of the subsequent sewage pipe network system. Therefore, when municipal manholes are blocked and require dredging, maintenance personnel need to go down into the manholes to carry out dredging operations. To ensure safety, the conventional practice is to use a water-blocking airbag placed inside the pipe, inflating it to block the incoming water, and then pumping water out of the manhole until the water level drops to a safe level before the personnel can enter the manhole.

[0003] Due to the complex water conditions and limited space in unblocked wells, the existing method of placing water-blocking airbags is relatively primitive. This involves workers placing uninflated water-blocking airbags directly into the target location inside the pipe from outside the well. However, since the airbags still have their own buoyancy even when they are not inflated, it is difficult to control the placement of the airbags into the well water and lower them to the target location. Furthermore, there are bends in the well pipes, resulting in poor visibility. Workers on the water surface and outside the well find it even more difficult to transport the airbags to the target location for inflation. Therefore, in order to complete the water-blocking task, workers still need to risk diving to place the airbags, which threatens their safety. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a precise delivery device for small-diameter municipal well water-blocking airbags. This effectively solves the problem of the relatively primitive method of placing water-blocking airbags in the existing well. That is, the operator directly places the uninflated water-blocking airbag into the target position inside the pipe from outside the well. However, since the airbag has its own buoyancy even when it is not inflated, it is difficult to control the airbag to be placed into the well water and lowered to the target position. In addition, there are bends between the well pipes, the visibility is poor, and it is even more difficult for the operator on the water surface and outside the well to deliver the airbag to the target position for inflation. Therefore, in order to complete the water-blocking task, the operator still needs to risk diving to place the airbag, which threatens the safety of the operator.

[0005] The technical solution provided by this utility model is to provide a small-diameter municipal well water-blocking airbag precision delivery device, including an airbag limiting cage. The bottom of the airbag limiting cage is provided with an airbag through a fixing mechanism. The top of the airbag limiting cage is provided with multiple pulleys at an incline through a limiting mechanism. One end of the airbag limiting cage is rotatably installed with a control rod through a bending joint mechanism.

[0006] Preferably, the fixing mechanism includes two electric grippers, which are symmetrically installed at the bottom of the airbag limiting cage. Two clamping blocks are symmetrically arranged on one side of the airbag, and the two electric grippers clamp one side of the two clamping blocks respectively.

[0007] Preferably, the limiting mechanism includes multiple fixing blocks, which are symmetrically installed in pairs on both sides of the top of the airbag limiting cage. A screw is rotatably installed at the central shaft of the pulley, and both ends of the screw are threaded onto one side of the two fixing blocks by nuts.

[0008] Preferably, the limiting mechanism includes two fixing plates respectively installed on both sides of the top of the airbag limiting cage. The top of each of the two fixing plates is provided with a sliding groove, and the pulley is slidably disposed in the sliding groove. Both sides of the two fixing plates are provided with screw slots. The two ends of the screw are slidably installed in the two screw slots on both sides of the fixing plates. The two nuts are respectively threaded onto the two ends of the screw, and the two nuts respectively abut against the two side walls of the fixing plates.

[0009] Preferably, the bending joint mechanism includes a positioning rod, which is installed at one end of the airbag limiting cage. A universal sleeve is installed on one side of the control rod, and a rotating ball is rotatably installed inside the universal sleeve. A sleeve is installed on the side of the rotating ball away from the universal sleeve, and the sleeve is sleeved around the periphery of the positioning rod.

[0010] Preferably, an air supply pipe is provided on one side of the airbag, and an anti-tangling component, which is a weight block, is provided on one side of the air supply pipe.

[0011] Preferably, the airbag limiting cage is provided with an anti-loss ring at one end near the control rod, and a rope is tied to the anti-loss ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses an airbag installed on an airbag limiting cage. The airbag limiting cage is then precisely transported to the target position inside the well using a control rod. Finally, the airbag is inflated through an air supply pipe to complete the water blocking operation of the sewage well from the ground. The entire process does not require workers to go down into the well, avoiding the risk of workers diving to place the airbag. It is safe, reliable, and convenient to use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1 to 2 The present invention provides a precise delivery device for airbags used for plugging water in small-diameter municipal wells, comprising an airbag limiting cage 1, a fixing mechanism, an airbag 2, a limiting mechanism, multiple pulleys 5, a bending joint mechanism, and a control rod 6.

[0024] Depend on Figures 3 to 4First, the airbag 2 is fixed on the airbag limiting cage 1 by a fixing mechanism. Specifically, the fixing mechanism includes two electric grippers 7 and two clamping blocks 8. The two electric grippers 7 are symmetrically installed on the bottom wall of the airbag limiting cage 1, and the two clamping blocks 8 are symmetrically installed on one side of the airbag 2. The two electric grippers 7 clamp and fix the two clamping blocks 8 respectively. Specifically, the airbag limiting cage 1 is a semi-circular or arc-shaped frame. The semi-circular or arc-shaped frame facilitates pushing into the manhole. The airbag limiting cage 1 temporarily fixes the airbag 2. The airbag limiting cage 1 pushes the airbag 2 into the manhole without the need for operators to go down into the manhole, avoiding the risk of operators diving to place the airbag. It also prevents the uninflated airbag 2 from deviating from the preset position due to its own buoyancy. The water blocking operation of the sewage manhole can be completed on the ground.

[0025] Depend on Figures 1 to 2 In addition, in order to better push the airbag limiting cage 1 into the well, multiple pulleys 5 are rotatably installed on the top of the airbag limiting cage 1 through a limiting mechanism. When the airbag limiting cage 1 is delivered into the well, the pulleys 5 abut against the top wall of the well. When the airbag limiting cage 1 is pushed, the pulleys 5 rotate, which facilitates the movement of the airbag limiting cage 1 in the well.

[0026] Specifically, the limiting mechanism includes multiple fixing blocks 11, nuts, and screws 12. The multiple fixing blocks 11 are symmetrically installed in pairs on the top of the airbag limiting cage 1. The screws 12 are rotatably installed at the central shaft of the pulleys 5. Both sides of the screws 12 are threadedly installed between the two fixing blocks 11 by nuts. More specifically, the multiple pulleys 5 are installed on both sides of the top of the airbag limiting cage 1 in an inverted V-shape structure. The inverted V-shape structure fits better against the top wall of the well.

[0027] Depend on Figures 5 to 6 Alternatively, the limiting mechanism may also include two fixed plates 13, two sliding grooves 14, and four screw slots 15.

[0028] Specifically, two fixing plates 13 are respectively installed on the top of the airbag limiting cage 1, two sliding grooves 14 are respectively opened through the top of the two fixing plates 13, four screw slots 15 are respectively opened on both sides of the two fixing plates 13, multiple pulleys 5 are respectively slidably installed in the two sliding grooves 14, the two ends of the screw 12 are respectively installed in the two screw slots 15 opened on both sides of the fixing plate 13, two nuts are respectively threaded on both sides of the screw 12, and the two nuts abut against the two side walls of the fixing plate 13. The pulleys 5 can slide in the sliding grooves 14 to adjust the position of the pulleys 5 on the airbag limiting cage 1.

[0029] During adjustment, loosen the nut and then push the pulley 5 to move in the sliding groove 14. The screw 12 also moves with the pulley 5 and moves in the screw groove 15. After the position adjustment is completed, tighten the nut so that the nut abuts against the side wall of the fixing plate 13.

[0030] Depend on Figures 1 to 2 Furthermore, the control lever 6 is mounted on one side of the airbag limiting cage 1 via a bending joint mechanism. The control lever 6 is used to push the airbag limiting cage 1 into the well, and can also adjust the position of the airbag limiting cage 1 in the well.

[0031] The bending joint mechanism includes a positioning rod 9, a universal sleeve 91, a rotating ball joint 92, and a sleeve 93. Specifically, the positioning rod 9 is installed at one end of the airbag limiting cage 1, the universal sleeve 91 is installed on one side of the control rod 6, the rotating ball joint 92 is rotatably installed inside the universal sleeve 91, and the sleeve 93 is installed on the side of the rotating ball joint 92 away from the universal sleeve 91, and the sleeve 93 is sleeved around the periphery of the positioning rod 9. The control rod 6 is installed on the positioning rod 9 through the sleeve 93. The sleeve 93 can be detached from the positioning rod 9 at any time. Pushing the control rod 6 can drive the airbag limiting cage 1 to move. During the movement, the angle of the control rod 6 can be adjusted through the universal sleeve 91 and the rotating ball joint 92.

[0032] An anti-loss ring 3 is provided at one end of the airbag limiting cage 1 near the control rod 6. A rope is tied inside the anti-loss ring 3. The rope makes it easy to pull the airbag limiting cage 1 out of the well, and also prevents the water flow from washing away the airbag limiting cage 1.

[0033] Depend on Figures 2 to 3 As given, finally, an air supply pipe 10 is provided on one side of the airbag 2, and an anti-entanglement component 4 is provided on one side of the air supply pipe 10. The anti-entanglement component 4 is a weight block. After the airbag 2 is placed in the predetermined position, the external air source inflates the airbag 2 through the air supply pipe 10, so that the airbag 2 expands to block water in the well. The weight block is to ensure that the air supply pipe 10 of the airbag 2 does not get entangled with the airbag limiting cage 1, and to ensure that the position of the airbag limiting cage 1 does not coincide with the position of the air supply pipe 10 when it moves.

[0034] The beneficial effects of the airbag limiting cage 1, fixing mechanism, airbag 2, limiting mechanism, multiple pulleys 5, bending joint mechanism and control rod 6 are as follows: the airbag 2 is installed on the airbag limiting cage 1, and then the airbag limiting cage 1 is accurately transported to the target position in the well using the control rod 6. Finally, the airbag 2 is inflated through the air supply pipe 10 to complete the water blocking operation of the sewage well on the ground. The entire process does not require operators to go into the well, avoiding the risk of operators diving to place the airbag 2. It is safe, reliable and convenient to use.

[0035] When using this utility model, first place the airbag limiting cage 1 inside the well, then use the control rod 6 to push the airbag limiting cage 1. When pushing, the pulley 5 will rotate on the top wall inside the well. The control rod 6 adjusts the airbag limiting cage 1 to the predetermined position inside the well. Then, use an external air source to inflate the airbag 2 through the air supply pipe 10. The airbag 2 seals the inside of the well. Finally, the electric gripper 7 releases the clamping block 8 and pulls the rope to pull the airbag limiting cage 1 out of the well.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
