Description

Technical Field

[0001] This utility model belongs to the field of conduit technology, specifically a device for air blowing and unblocking conduits after pouring. Background Technology

[0002] Pre-embedded electrical and plumbing conduits refer to the conduits that are pre-installed in the structure of walls, floors, or slabs during the construction process to facilitate the subsequent installation of electrical facilities such as wires and cables. To prevent the conduits from becoming clogged and affecting the subsequent installation of the lines, air needs to be blown through the conduits to clear any blockages after the cement is poured.

[0003] Among them, a search revealed an application with application number CN202320043051.7, which discloses a device for quickly checking for blockages in conduits. The device includes a pre-embedded conduit, with a vertically upward-facing inspection tube connected to the outer wall of the conduit. When it is necessary to check for blockages inside the pre-embedded conduit, the inspection tube, with a load-bearing ball inside, allows air to be blown from the connection point of the conduit using a blower. If the conduit is blocked, the load-bearing ball will move upwards within the inspection tube. The position of the load-bearing ball within the inspection tube can quickly determine the blockage status of the conduit, enabling timely unblocking or re-embedding of the conduit, thus avoiding delays in wiring progress. It can also be used to unblock blocked conduits and remove debris that has fallen into them, avoiding damage to completed construction surfaces and poor aesthetic quality after repairs.

[0004] However, research has revealed that while this device determines conduit blockage by observing the position of the load-bearing ball, the position of the load-bearing ball changes when the conduit is tilted, making the accuracy of determining blockage insufficient. Furthermore, the device is not convenient for marking blocked conduits and lacks a structure for sealing conduit openings, requiring the use of traditional tape sealing methods, which are cumbersome and inconvenient. Therefore, a new device is proposed to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a device for unblocking conduits by blowing air after they have been poured, in order to solve the problems of insufficient accuracy and inconvenience in judging the blockage of conduits.

[0006] The technical solution adopted by this utility model is as follows: a device for blowing air to clear blockages after the casting of a conduit, including a support frame, a storage box fixedly installed on one side above the support frame, and a sealing plug inside the storage box;

[0007] An air blowing mechanism is provided above the support frame to facilitate the removal of blockages in the conduit.

[0008] The air blowing mechanism includes an air pump, an air blowing pipe, an air guiding chamber, a sealing ball, and a fan plate. The air pump is fixedly installed in the middle of the upper part of the support frame. The air pump outlet pipe is connected to the air blowing pipe, and the outlet of the air blowing pipe is arranged in a mountain shape. An air guiding chamber is embedded in one side of the air blowing pipe, and a sealing ball is elastically connected to the air guiding chamber. A fan plate is rotatably connected to the outlet of the air guiding chamber via a rotating shaft, and the fan plate is elastically connected to the outlet of the air guiding chamber via a spring. A handle is fixedly installed in one side of the air blowing pipe, and a control switch is installed above the handle. A fixing groove is fixedly installed in the other side of the upper part of the support frame, and the air blowing pipe is placed in the fixing groove. An ink tank is embedded in one side of the outlet of the air blowing pipe, and an ink filling port is provided above it. A rubber sealing plug is installed at the ink filling port. A sealing cap is threadedly connected to the opening of one side of the ink tank, and a sponge pad is glued to the side of the sealing cap facing the ink tank.

[0009] The sealing plug has a connecting column fixedly installed at the lower center, and clamps are symmetrically and elastically connected to both sides of the connecting column. The contact area between the clamps and the inner wall of the conduit is arc-shaped. Connecting rods are elastically connected to both sides of the sealing plug and the clamps through through grooves.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] 1. In this utility model, when the inside of the conduit is completely blocked by foreign objects, the gas inside the air blowing mechanism is introduced into the air guiding chamber. The air pressure pushes the sealing ball to move, so that the gas is discharged from the outlet of the air guiding chamber. During the exhaust process at the outlet of the air guiding chamber, the fan plate is pushed into an inclined state by the airflow and extends out from the outlet of the air guiding chamber. The operator can more intuitively see the airflow being discharged from the outlet of the air guiding chamber, thereby judging that the conduit is blocked. The fan plate will not extend out from the outlet of the air guiding chamber due to the inclination of the air blowing pipe, making the judgment of the conduit blockage more accurate.

[0012] 2. In this utility model, by twisting the sealing cap, the sponge pad comes into contact with the blocked conduit, and the ink on the sponge pad is printed on the conduit, making it easy to mark the blocked conduit.

[0013] 3. In this utility model, the connecting rod of the sealing plug is inserted into the conduit. The two clamps are firmly held on both sides of the inner wall of the conduit under the action of the spring, fixing the sealing plug at the opening of the conduit and sealing the opening of the conduit. Compared with the tape sealing method, this method is more convenient to use. When installing the wiring into the conduit later, by pressing the two connecting rods, the connecting rods push the clamps to rotate away from the inner wall of the conduit, and the sealing plug can be easily removed from the opening of the conduit. The sealing plug can be reused. Attached Figure Description

[0020] 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.

[0021] In this utility model:

[0022] Reference Figure 1-5 A device for blowing air to clear blockages after the casting of a conduit includes a support frame 1, a storage box 101 fixedly installed on one side above the support frame 1, and a sealing plug 2 inside the storage box 101.

[0023] An air blowing mechanism is provided above the support frame 1 to facilitate the removal of blockages in the tubing.

[0024] Reference Figure 1-4In this embodiment, the air blowing mechanism includes an air pump 102, an air blowing pipe 1021, an air guiding chamber 1022, a sealing ball 1023, and a fan plate 1024. The air pump 102 is fixedly installed in the middle of the upper part of the support frame 1. The outlet pipe of the air pump 102 is connected to the air blowing pipe 1021, and the outlet of the air blowing pipe 1021 is arranged in a mountain shape. The air guiding chamber 1022 is embedded in one side of the air blowing pipe 1021, and the sealing ball 1023 is elastically connected to the air guiding chamber 1022. The fan plate 1024 is rotatably connected to the outlet of the air guiding chamber 1022 via a rotating shaft, and the fan plate 1024 is elastically connected to the outlet of the air guiding chamber 1022 via a spring. A handle 1025 is fixedly installed in one side of the air blowing pipe 1021, and a control switch 1026 is installed above the handle 1025. A fixing groove 103 is fixedly installed in the other side of the upper part of the support frame 1, and the air blowing pipe 1021 is placed inside the fixing groove 103.

[0025] The device is pushed to the pre-buried location of the conduit. The air blowing pipe 1021 inside the fixing groove 103 is removed. Then, the outlet of the air blowing pipe 1021 is inserted into the opening of the conduit. The operator presses the control switch 1026 to control the air pump 102 to work. The air pump 102 blows out gas and blows the gas into the conduit through the air blowing pipe 1021 to blow out the small blockages inside the conduit and clear them. When the inside of the conduit is completely blocked by foreign objects, the gas inside the air blowing pipe 1021 is introduced into the air guide chamber 1022. The air pressure pushes the sealing ball 1023 to move, so that the gas is discharged from the outlet of the air guide chamber 1022. During the exhaust process at the outlet of the air guide chamber 1022, the fan plate 1024 is pushed into an inclined state by the airflow and extends out from the outlet of the air guide chamber 1022. The operator can more intuitively see the airflow being discharged from the outlet of the air guide chamber 1022, thereby judging that the conduit is blocked.

[0026] Reference Figure 2 , 3 5. In this embodiment, an ink trough 104 is embedded on one side of the outlet of the air blowing pipe 1021, and an ink filling port is provided above it. A rubber sealing plug is installed at the ink filling port. A sealing cover 1041 is threaded to the opening on one side of the ink trough 104, and a sponge pad 1042 is adhered to the side of the sealing cover 1041 facing the ink trough 104.

[0027] The staff unscrewed the sealing cap 1041 and brought the sponge pad 1042 into contact with the blocked conduit. The ink on the sponge pad 1042 was imprinted on the conduit, marking the blocked conduit. The conduit will then be re-buried according to the location and number of blocked conduits.

[0028] Reference Figure 2-3In this embodiment, a connecting post 201 is fixedly installed in the middle of the lower part of the sealing plug 2. Clamping plates 202 are symmetrically and elastically connected on both sides of the connecting post 201. The contact area between the clamping plates 202 and the inner wall of the conduit is arc-shaped. Connecting rods 203 are elastically connected to the sealing plug 2 at the corresponding positions of the clamping plates 202 through through grooves.

[0029] After the conduit is cleared, the sealing plug 2 is taken out from the storage box 101. The connecting post 201 of the sealing plug 2 is inserted into the conduit. The two clamps 202 are firmly clamped on both sides of the inner wall of the conduit under the action of the spring, fixing the sealing plug 2 at the opening of the conduit and sealing the opening of the conduit to prevent external impurities from entering the conduit and causing blockage. When installing the wiring into the conduit later, by pressing the two connecting rods 203, the connecting rods 203 push the clamps 202 to rotate away from the inner wall of the conduit, and the sealing plug 2 can be easily removed from the opening of the conduit. The sealing plug 2 can be reused.

[0030] Reference Figure 1-2 In this embodiment, the air pump 102 is electrically connected to an external power supply via a control switch 1026.

[0031] Working principle: First, push the device to the pre-buried conduit location, remove the air blowing pipe 1021 inside the fixing groove 103, and then insert the outlet of the air blowing pipe 1021 into the conduit opening. The operator presses the control switch 1026 to control the air pump 102 to work. The air pump 102 blows out gas, which is then blown into the conduit through the air blowing pipe 1021 to blow out and clear any small blockages inside the conduit. Next, take out the sealing plug 2 from inside the storage box 101, and insert the connecting post 201 of the sealing plug 2 into the conduit. The two clamps 202 are firmly clamped on both sides of the conduit's inner wall under the action of springs, fixing the sealing plug 2 at the conduit opening to seal the opening and prevent external impurities from entering and causing blockages. Then, continue to clear other conduits. When the inside of a conduit is completely blocked by foreign objects, the air blowing pipe 1021... Gas is introduced into the air guide chamber 1022. The air pressure pushes the sealing ball 1023 to move, causing the gas to be discharged from the outlet of the air guide chamber 1022. During the exhaust process at the outlet of the air guide chamber 1022, the fan plate 1024 is pushed into an inclined state by the airflow and extends out from the outlet of the air guide chamber 1022. The staff can more intuitively see the airflow being discharged from the outlet of the air guide chamber 1022, thereby determining that the conduit is blocked. The staff unscrews the sealing cap 1041 and contacts the sponge pad 1042 with the blocked conduit. The ink on the sponge pad 1042 is imprinted on the conduit, achieving the purpose of marking the blocked conduit. Finally, when installing the wiring inside the conduit, by pressing the two connecting rods 203, the connecting rods 203 push the clamp 202 to rotate away from the inner wall of the conduit, and the sealing plug 2 can be easily removed from the opening of the conduit. The sealing plug 2 can be reused.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
