Abstract
Description
Technical Field
[0001] The present application relates to the technical field of municipal pipe well delivery tools, and in particular to a municipal pipe well water plugging airbag precision delivery device. Background Art
[0002] At present, the municipal sewage pipe network is a huge systematic project. Municipal sewage pipe wells are widely distributed in every corner of the city. Since the municipal sewage pipe wells are the main body directly connecting the sewage pipe network with the outside world of the city, in the long-term sewage discharge and drainage process, most of the silt blockage occurs in the municipal sewage pipe wells. The blockage of the municipal sewage pipe outlet by silt directly affects the sewage discharge and drainage function of the subsequent sewage pipe network system.
[0003] In the relevant technology, when a municipal pipe well is blocked and needs to be desilted, the operation and maintenance personnel are required to go down the well to carry out the desilting operation. To ensure safety, the conventional practice is to place a water-blocking airbag in the pipe, inflate it to block the incoming water, pump water out of the well and wait until the water level in the well drops to the safety requirement before the operators can go down the well.
[0004] With respect to the above-mentioned related technologies, the inventor of the utility model believes that: due to the complex water conditions and limited space in the unplugged pipe well, the method of placing the water-plugging airbags in the related technology is relatively primitive, that is, the operating personnel directly place the uninflated water-plugging airbags into the target position in the pipe outside the well. However, since the plugging airbags have their own buoyancy even when they are not inflated, it is difficult to control the airbags to be placed in the pipe well water and lowered to the target position. In addition, there are turns between the pipe well pipelines, and the visual environment is poor. It is even more difficult for the operating personnel on the water surface and outside the well to transport the airbags to the target position and inflate them. Therefore, in order to complete the water-plugging task, the operating personnel still need to risk diving to place the airbags, which threatens the safety of the operating personnel. Utility Model Content
[0005] The purpose of the present application is to provide a precise conveying device for municipal pipe well water plugging airbags, so as to solve the problem that the plugging airbags have their own buoyancy even when not inflated, making it difficult to control the airbags to be placed in the pipe well water and lowered to the target position, and there are turns between the pipe well pipelines, resulting in poor visual environment, and it is even more difficult for operators on the water surface and outside the well to convey the airbags to the target position and inflate them. Therefore, in order to complete the water plugging task, operators still need to risk diving to place the airbags, which threatens the safety of the operators.
[0006] The municipal pipe well water plugging airbag precise delivery equipment provided in this application adopts the following technical solution:
[0007] A municipal pipe well water plugging airbag precision conveying device comprises an airbag limiting cage, in which an airbag is placed, and the airbag limiting cage is provided with a plurality of limiting members for limiting the airbag, and a propulsion mechanism is also provided between the inner bottom of the airbag limiting cage and the airbag, and the propulsion mechanism is used to pull the airbag out of the airbag limiting cage.
[0008] Furthermore, the airbag limiting cage includes a plurality of limiting U-shaped rods, both ends of the plurality of limiting U-shaped rods are symmetrically provided with limiting top rods, and the bottoms of the plurality of limiting U-shaped rods are provided with limiting bottom rods.
[0009] Furthermore, the propulsion mechanism includes a plurality of propulsion pulleys which are rotatably arranged on one side of the limiting bottom rod and the limiting U-shaped rod, a propulsion rod is slidably arranged between the plurality of propulsion pulleys, a propulsion handle is arranged at one end of the propulsion rod, and a clamping assembly is arranged between one end of the propulsion rod away from the propulsion handle and one end of the airbag.
[0010] Furthermore, the clamping assembly includes a propulsion strap connected to one end of the airbag, and a clamping groove clamped with the propulsion strap is formed at one end of the propulsion rod away from the propulsion handle.
[0011] Furthermore, the plurality of propulsion pulleys are staggered and abut against the outer side of the propulsion rod in sequence.
[0012] Furthermore, the limiting member is an opening and closing hoop, one end of which is rotatably arranged on one side of the airbag limiting cage.
[0013] Furthermore, an inflation tube is provided at one end of the airbag.
[0014] Furthermore, the airbag limiting cage has an overall arc-shaped structure.
[0015] Furthermore, a transport extension rod is provided at one end of the airbag limiting cage.
[0016] Furthermore, the bottom of the airbag limiting cage is also provided with moving wheels.
[0017] Compared with the prior art, the beneficial effect of the present application lies in that by setting up a structure in which the airbag limiting cage, airbag, limiting member and propulsion mechanism cooperate with each other, not only can the uninflated airbag be accurately transported to the target position of the underground sewage pipe to complete the inflation and water plugging operation, but the entire operation can be carried out by the operators outside the ground sewage well, which is safe and convenient.

DETAILED DESCRIPTION
[0022] The following is combined with Figure 1-Figure 3 This application is described in further detail.
[0023] The present application embodiment discloses a municipal pipe well water plugging airbag precise delivery device, referring to Figure 1 In this embodiment, the conveying device includes an airbag limiting cage 1, an airbag 2, a limiting member 3 and a propulsion mechanism. The airbag 2 is placed flat inside the airbag limiting cage 1, and an inflation tube 21 is installed at the left end of the airbag 2. The airbag 2 is inflated through the inflation tube 21, so that the inflated airbag 2 can be used for water blocking operations.
[0024] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the airbag limiting cage 1 includes a limiting U-shaped rod 11, a limiting top rod 12 and a limiting bottom rod 13. The limiting U-shaped rod 11 and the limiting top rod 12 are both provided with two, and the two limiting top rods 12 are symmetrically installed between the two corresponding ends of the two limiting U-shaped rods 11, and the two limiting U-shaped rods 11 are respectively located at the two ends of the limiting top rod 12; the two ends of the limiting bottom rod 13 are respectively installed at the bottom of the two limiting U-shaped rods 11, so as to support the airbag 2, so that the airbag 2 can be placed flat in the airbag limiting cage 1.
[0025] Preferably, the airbag limiting cage 1 has an overall arc-shaped structure, specifically: the limiting top rod 12 and the limiting bottom rod 13 are both arc-shaped structures, so that the main body of the airbag limiting cage 1 can be bent smoothly to adapt to the turning point of the pipe well and the pipeline, so that the airbag limiting cage 1 can achieve the accurate transportation of the uninflated airbag 2 along the ground sewage well 8 to the target position of the underground sewage pipe 9, and then complete the inflation and water blocking operation.
[0026] At the same time, refer to Figure 1In this embodiment, a plurality of limiting members 3 are provided, and the plurality of limiting members 3 are respectively provided on one side of the airbag limiting cage 1; specifically, the limiting member 3 is an opening and closing hoop, one end of which is rotatably mounted on the limiting top rod 12 of the airbag limiting cage 1. The setting of the opening and closing hoop facilitates the top of the airbag limiting cage 1 to be firmly limited, and when transported underwater, it can prevent the airbag 2 from being separated from the outside of the airbag limiting cage 1 in advance due to its own buoyancy. The limiting member 3 can also be other limiting structures that can firmly limit the airbag 2 in the airbag limiting cage 1.
[0027] In addition, refer to Figure 1 and Figure 3 In this embodiment, the propulsion mechanism is arranged between the inner bottom of the airbag limiting cage 1 and the airbag 2, so as to pull the airbag 2 out of the airbag limiting cage 1, thereby using the airbag 2 to perform inflation and water blocking operations.
[0028] Specifically, in this embodiment, the propulsion mechanism includes a propulsion pulley 4, a propulsion rod 5, a propulsion handle 51 and a clamping assembly. Among them, there are multiple propulsion pulleys 4, and the multiple propulsion pulleys 4 are respectively installed on one side of the limiting bottom rod 13 and the limiting U-shaped rod 11. More specifically, in this embodiment, there are three propulsion pulleys 4 installed in total, two of which are installed on one side of the limiting bottom rod 13, and the remaining propulsion pulley 4 is installed on one side of the limiting U-shaped rod 11 on the right side.
[0029] At the same time, the propulsion rod 5 is slidably installed between the propulsion pulleys 4, and the two ends of the propulsion rod 5 extend out of the outside of the two limiting U-shaped rods 11 respectively, and the propulsion pulleys 4 are staggered and abutted against the outside of the propulsion rod 5 in sequence, which not only can effectively limit and guide the propulsion rod 5, but also can assist the movement of the propulsion rod 5, so that the propulsion rod 5 can slide more stably between the propulsion pulleys 4.
[0030] Preferably, the three propulsion pulleys 4 are located on the same straight line, so that the propulsion rod 5 can avoid being separated from the outside of the propulsion pulley 4 when sliding and propulsion. And the propulsion handle 51 is installed at the left end of the propulsion rod 5, and the propulsion handle 51 is provided to facilitate the push-pull sliding of the propulsion rod 5.
[0031] In addition, refer to Figure 1 and Figure 3In this embodiment, the clamping assembly is arranged between the end of the propulsion rod 5 away from the propulsion handle 51 and the right end of the airbag 2; specifically, the clamping assembly includes a propulsion strap 22 and a clamping slot 52. The propulsion strap 22 is installed on the end of the airbag 2 away from the inflation tube 21; the clamping slot 52 is provided on the end of the propulsion rod 5 away from the propulsion handle 51, and the propulsion strap 22 and the clamping slot 52 cooperate with each other, so that the end of the propulsion strap 22 away from the airbag 2 is clamped on the clamping slot 52.
[0032] When the airbag limiting cage 1 transports the airbag 2 to the target position in the pipeline, the operator pushes the propulsion rod 5 forward through the propulsion handle 51. With the assistance of the propulsion pulleys 4, the propulsion rod 5 completes the action of pulling the airbag 2 out of the airbag limiting cage 1 through the propulsion strap 22, thereby transporting the airbag 2 to the target position of the underground sewage pipe 9.
[0033] Therefore, by setting up a structure in which the airbag limiting cage 1, the airbag 2, the limiting member 3 and the propulsion mechanism cooperate with each other, not only can the uninflated airbag 2 be accurately transported along the ground sewage well 8 to the target position of the underground sewage pipe 9 to complete the inflation and water blocking operation, but the entire operation can be carried out by the operators outside the ground sewage well 8, which is safe and convenient.
[0034] Secondly, refer to Figure 1 and Figure 2 In the present embodiment, a transport extension rod 6 is installed on one end of the airbag limiting cage 1. The provision of the transport extension rod 6 facilitates the operator to move the airbag limiting cage 1 from the outside of the ground sewage well 8 to the inside of the ground sewage well 8.
[0035] Furthermore, since the airbag limiting cage 1 is heavy, workers outside the well need to move the airbag limiting cage 1 into the underground sewage pipe 9. Therefore, in this embodiment, moving wheels 7 are also installed at the bottom of the airbag limiting cage 1. The setting of the moving wheels 7 can provide support and facilitate movement in the underground sewage pipe 9.
[0036] The implementation principle of a municipal pipe well water plugging air bag precision conveying device in an embodiment of the present application is as follows: when it is necessary to carry out water plugging operations in an underground sewage pipe 9, the operator moves the air bag limiting cage 1 from the outside of the ground sewage well 8 to the inside of the ground sewage well 8 by carrying the extension rod 6, and uses the air bag limiting cage 1 to convey the uninflated air bag 2 to the target position in the pipe. Then the operator pushes the propulsion rod 5 forward by the propulsion handle 51, and with the assistance of the propulsion pulleys 4, the propulsion rod 5 completes the pulling out of the air bag 2 from the air bag limiting cage 1 through the propulsion strap 22, and finally inflates the air bag 2 through the inflation tube 21, thereby using the inflated air bag 2 to complete the process of water plugging operations in the underground sewage pipe 9.

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.
