Description

Technical Field

[0001] The utility model relates to the technical field of gas pipe networks, and specifically provides a gas pipe network drainage device. Background Art

[0002] There are often multiple water blockages in the low-pressure pipe network of a residential area, and it is difficult to determine the location of the water blockage. In the traditional drainage method, the water will be drained from the condensate tank first. If it cannot be completely drained, the clamps can be used appropriately according to the actual situation to drain the water in sections. Before draining, the valves and pressure regulating boxes near the water-blocked pipeline that are not involved in the purge should be closed. The introduced branch pipes should be checked one by one to confirm that the valves of the connected gas riser are in the closed state. A compressor is set at the high point of the gas pipeline network to pressurize the air, and multiple drain ports are set at the riser. When the compressor is pressurized to a certain pressure, the drain port is quickly opened. After repeated discharges, the accumulated water in the pipe can be discharged. When the drain port cannot drain water, a tightness test and leak detection are carried out. After passing the test, the valve is opened to resume gas supply.

[0003] In the prior art, there is also a method of draining water by combining a hose and a pump. When in use, one end of the hose is inserted from a three-way joint of the gas pipe network, and the inserted end of the hose is pushed to a low-lying part of the gas pipe network. The other end of the hose is connected to the pump, and the water accumulated in the low-lying part of the gas pipe network is pumped out by the pump. This method only requires the use of valves on the gas pipe network to separate the low-lying parts, and then the water can be pumped out by the pump and the hose. After the water accumulated in each low-lying part of the gas pipe network is pumped out, the effect of draining the gas pipe network can be achieved.

[0004] However, when draining water through a pump and a hose, one end of the hose needs to be moved to a low-lying area of ​​the gas pipe network, and the low-lying areas of the gas pipe network are at different distances from the hose insertion position. If the low-lying area is short from the hose insertion position, it is easy to push the hose to the low-lying area. If the low-lying area is long from the hose insertion position, the hose is easily blocked during movement and curled, making it difficult for the hose to reach the low-lying area, seriously affecting the pumping efficiency. Utility Model Content

[0005] The utility model provides a gas pipe network drainage device, which is used to solve the problem that when the low-lying place is far away from the insertion position of the hose, the hose is difficult to reach the low-lying place, thus affecting the water pumping efficiency.

[0006] The technical solution of the utility model is as follows:

[0007] A gas pipe network drainage device comprises a bracket, an air pump, a water pump, a hose and a nozzle, wherein a first joint is provided at one end of the hose, and the other end of the hose is connected to the nozzle, the air pump and the water pump are respectively provided with a second joint adapted to the first joint, the first joint is connected to the second joint of the air pump or the water pump, the air pump and the water pump are respectively connected to the bracket, and the nozzle is provided with an air jet hole, the air jet hole faces one side of the hose, and the air jet hole is connected to the hose.

[0008] In this solution, one end of the hose is connected to the nozzle, and the nozzle is provided with an air jet hole. When the other end of the hose is connected to the air pump, the air pump supplies gas to the hose, and the input gas is ejected from the air jet hole of the nozzle. The air jet hole of the nozzle is located on the side close to the hose. Therefore, the nozzle is subjected to a reaction force when ejecting gas, so that the nozzle moves forward, thereby driving the hose to move along the pipeline direction of the gas pipe network, and the end of the hose can be brought to the low-lying part of the gas pipe network through the nozzle. Since the hose is pulled by the nozzle, the end of the hose will not curl in the gas pipe network due to factors such as friction resistance, and the end of the hose can be quickly and efficiently moved to the low-lying part of the gas pipe network through the nozzle. At the same time, under the gravity of the nozzle, it can be ensured that the end of the hose is close to the bottom of the gas pipe network. After the nozzle moves to the low-lying place, the first joint is connected to the second joint on the water pump, and the water in the low-lying place is pumped out by the water pump. The accumulated water in the low-lying areas can enter from the jet holes, enter the inside of the nozzle from the jet holes, then enter the hose from the inside of the nozzle, and finally be pumped out by the water pump.

[0009] In order to solve the problem that it is difficult to determine the position of the nozzle and whether the nozzle has reached the low-lying part of the gas pipeline network, the hose is provided with a scale, and the scale is arranged along the axis direction of the hose.

[0010] In this solution, the length of the hose inserted into the gas network can be calculated through the scale. By comparing the distance between the low point of the gas network and the position where the hose is inserted, the position of the nozzle can be determined, so that the nozzle can be accurately moved to the low point of the gas network.

[0011] In order to solve the problem that the nozzle falls off the hose when the hose is recovered, the device also includes a safety rope, one end of which is fixedly connected to the nozzle, and the other end of the safety rope is connected to the bracket.

[0012] In this solution, a safety rope is connected to the nozzle. When the hose is recovered, the hose and the safety rope are pulled at the same time to reduce the force between the hose and the nozzle. The safety rope is used to share the resistance when the nozzle moves, thereby preventing the nozzle from detaching.

[0013] In order to solve the problem that the safety rope is easy to slip when being pulled manually, a winch mechanism is provided on the bracket, and the safety rope is stored in the winch mechanism.

[0014] In this solution, the safety rope is recovered by a winch mechanism, which can prevent the safety rope from slipping and ensure recovery efficiency.

[0015] In order to solve the problem that the nozzle rotates continuously during movement, causing the hose to bend and deform due to rotation, thereby further causing the hose to be unable to transport accumulated water, an eccentric block is provided in the nozzle to shift the center of gravity of the nozzle to one side of the axis.

[0016] In this solution, since the center of gravity of the nozzle is offset, the probability of the nozzle rotating during movement can be greatly reduced, thereby reducing the rotation of the hose, avoiding the hose from being squeezed and deformed due to rotation, and preventing the hose from being unable to transport accumulated water.

[0017] In order to solve the problem that the jet hole is located on the upper side of the axis of the nozzle, resulting in a high water pumping position, the jet hole and the eccentric block are located on the same side of the axis of the nozzle.

[0018] In this solution, the jet hole and the eccentric block are located on the same side. After the nozzle stops, the eccentric block is located on the lower side of the axis of the nozzle. At this time, the jet hole is also located on the lower side of the axis of the nozzle, ensuring that the jet hole is located low, thereby ensuring that the jet hole can extract water accumulated at a lower position.

[0019] In order to solve the problem that the nozzle is blocked by scaling and other substances in the pipeline, the end of the nozzle away from the hose is tapered.

[0020] In this solution, the scaling material will contact the conical part, the surface of the conical part is a conical surface, and under the guidance of the conical surface, the nozzle will tilt downward, and then pass over the scaling material under the force formed by the jet from the jet hole, thereby improving the passability of the nozzle in the pipeline.

[0021] The nozzle will continue to be subjected to the force generated by the jet from the jet hole during the movement. At this time, the position of the eccentric block of the nozzle may change, causing the center of gravity of the nozzle to tilt. In order to solve the problem that the eccentric block cannot be rotated to the lower side of the axis after the nozzle stops moving forward, the middle part of the nozzle is cylindrical.

[0022] In this solution, the middle part of the nozzle is set to be cylindrical. When the eccentric block is not located directly below the axis of the nozzle, the nozzle can rotate under the gravity of the eccentric block, so that the eccentric block is located directly below the axis of the nozzle.

[0023] In order to solve the problem of difficulty in carrying the device, casters are arranged at the bottom of the bracket.

[0024] In this solution, after the casters are provided, the device can be pushed manually, which reduces the difficulty of transportation.

[0025] In order to solve the problem that the device is easy to move when in use, the casters are provided with a locking structure.

[0026] In this solution, a locking structure is provided to lock the casters, and after the casters are locked, the device can be prevented from moving.

[0027] Beneficial effects of the utility model:

[0028] The utility model has a nozzle at the end of the hose, and the nozzle is moved by the air pump. The movement of the nozzle pulls the hose to move, so that the hose can be quickly moved to the low-lying part of the gas pipe network. Regardless of whether the distance between the hose insertion position and the low-lying part is close or far, the problem of the hose end being curled in the pipeline due to friction resistance can be solved, and the placement efficiency of the hose can be improved, and the efficiency of water accumulation treatment can be improved.

[0034] In conjunction with the accompanying drawings, the technical solution of the present utility model is clearly and completely explained through the specific implementation methods of the embodiments of the present utility model.

[0035] Embodiment 1.

[0036] like Figure 1As shown, the first embodiment provides a gas pipe network drainage device, including a bracket 1, on which an air pump 5 and a water pump 3 are installed, the output end of the air pump 5 is provided with a second connector 4, and the input end of the water pump 3 is provided with another second connector 4. The second connectors 4 on the air pump 5 and the water pump 3 are both used to connect with the first connector 6, and the first connector 6 is provided on a hose 8. One end of the hose 8 is connected to the first connector 6, and the other end of the hose 8 is provided with a nozzle 9, and the nozzle 9 is provided with an air jet hole 93, and the air jet hole 93 is located on a side close to the hose 8. In other words, the hose 8 can be connected to the air pump 5 or the water pump 3. When the hose 8 is connected to the air pump 5, the air pump 5 delivers air into the hose 8. After the air is delivered to the nozzle 9, it is ejected from the air jet hole 93 of the nozzle 9. When the air jet hole 93 ejects air, a force acting on the nozzle 9 is generated to push the nozzle 9 to move. The moving direction of the nozzle 9 is opposite to the jet direction of the jet hole 93. During the movement of the nozzle 9, the hose 8 will be pulled forward, thereby pulling the hose 8 to the low-lying part of the gas pipe network. The position of the nozzle 9 can be determined by estimating the length of the hose 8 entering the gas pipe network and then comparing the distance of the low-lying part of the gas pipe network at the position where the hose 8 is placed. When it is determined that the nozzle 9 has moved to the low-lying part of the gas pipe network, the first connector 6 is connected to the second connector 4 of the water pump 3, and the water pump 3 pumps out the accumulated water in the low-lying part of the gas pipe network through the hose 8. The accumulated water enters the nozzle 9 from the jet hole 93, then enters the hose 8 from the nozzle 9, and is finally pumped out by the water pump 3.

[0037] The nozzle 9 is cylindrical in shape as a whole, and the end of the nozzle 9 away from the hose 8 is conical. That is, the end of the nozzle 9 away from the hose 8 is formed with a conical surface, which can facilitate the nozzle 9 to pass over obstacles in the pipeline. For example, when there are scale and other substances in the pipeline of the gas network, the conical surface can play a guiding role, so that the nozzle 9 tilts upward to pass over the obstacle.

[0038] like Figure 2 As shown, the nozzle 9 is provided with an air jet hole 93, and an eccentric block 95 is provided inside the nozzle 9. The eccentric block 95 and the air jet hole 93 are arranged on the same side of the axis of the nozzle 9. Under the gravity of the eccentric block 95, the center of gravity of the nozzle 9 is offset to one side of the eccentric block 95. Therefore, when the nozzle 9 is placed in the pipeline, the eccentric block 95 will always be located directly below the axis of the nozzle 9. Therefore, the position of the air jet hole 93 located on the same side as the eccentric block 95 is also located at the lowest position that the air jet hole 93 can reach, so that the air jet hole 93 can extract water at a lower water level.

[0039] The eccentric block 95 is a block structure with a density greater than that of the nozzle 9, for example, a metal cuboid with a higher density can be used. The eccentric block 95 can be fixed to the nozzle 9 by fasteners such as screws, or can be welded to the nozzle 9. When installing the eccentric block 95, a mounting groove 94 can be opened on the side of the nozzle 9, and the eccentric block 95 can be installed in the mounting groove 94. The mounting groove 94 can also be opened on the end surface of the nozzle 9, and the eccentric block 95 can be installed in the groove.

[0040] The nozzle 9 is preferably provided with one jet hole 93. If multiple jet holes 93 are provided, all the jet holes 93 need to be located at the same height when the eccentric block 95 is located directly below the axis of the nozzle 9. Otherwise, when pumping water, one jet hole 93 is located above the liquid surface, making it difficult to form a negative pressure in the hose 8, and thus it is difficult to pump out the accumulated water. Therefore, the preferred embodiment of the nozzle 9 is to only provide one jet hole 93.

[0041] When the eccentric block 95 is located directly below the axis of the nozzle 9, the jet hole 93 is tilted downward, so that the jet outlet of the jet hole 93 is located at a lower position, and the accumulated water at a lower position can be extracted.

[0042] The nozzle 9 is provided with a tubular joint 92 , and the hose 8 is sleeved on the tubular joint 92 and fixed to the tubular joint 92 via a clamp.

[0043] The nozzle 9 is also provided with a pull ring 91, and the bracket 1 is provided with a safety rope 7, one end of the safety rope 7 is fixed to the bracket 1, and the other end of the safety rope 7 is connected to the pull ring 91. After the water extraction work is completed, the hose 8 and the nozzle 9 need to be taken out. When the hose 8 is pulled and the nozzle 9 is taken out by the hose 8, if the nozzle 9 is separated from the hose 8 due to resistance, the nozzle 9 cannot be taken out. Therefore, by connecting the safety rope 7 to the nozzle 9, the nozzle 9 can be pulled out through the safety rope 7. The safety rope 7 can also reduce the force exerted on the hose 8 by the nozzle 9 to prevent the hose 8 from being separated from the nozzle 9.

[0044] The support 1 is provided with a hoisting mechanism 10, and the safety rope 7 is connected to the hoisting mechanism 10. The safety rope 7 is retracted and released by the hoisting mechanism 10, so that the safety rope 7 can be prevented from slipping when manually pulled.

[0045] A caster 2 is provided at the bottom of the bracket 1. The caster 2 can be a universal wheel in the prior art to facilitate the steering of the bracket 1. A universal wheel with a locking structure in the prior art can also be selected. The universal wheel can be locked by the locking structure during operation to prevent the bracket 1 from moving.

[0046] The bracket 1 may be a frame structure formed by welding profiles. The air pump 5 and the water pump 3 are fixed to the bracket 1 by bolts and other fasteners. The water pump 3 may be a hand pump to reduce the weight of the entire device. The bracket 1 may also be equipped with a battery for the air pump 5, and the battery is used to power the air pump 5.
