Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a convenient conduit unblocking / blocking identification device. Background Technology

[0002] During construction, water and electricity pipelines need to be embedded in concrete for later use in electrical wiring or underfloor heating installation. However, during concrete pouring, some concrete may flow into the embedded pipes, causing internal blockages. Although some of the concrete flowing into the pipes may not completely seal them, the uneven concrete can prevent the wires from being laid smoothly. Currently, there is a lack of effective detection methods during construction. Problems are usually only discovered when the wires cannot pass through the pipes properly during wiring, requiring temporary solutions. There is currently a lack of a device that can easily detect the patency of the conduits. Summary of the Invention

[0003] The purpose of this invention is to provide a convenient conduit unblocking / blocking identification device to solve the problems mentioned in the background art.

[0004] A portable conduit patency / blockage detection device includes a pneumatic unit. The pneumatic unit includes a gripping shell with a gas generating device inside. A connecting pipe is fixedly connected to the end of the pneumatic unit, and an indicator unit is fixedly connected to the top of the connecting pipe. The indicator unit includes an observation tube, the lower end of which is connected to the connecting pipe. The upper end of the observation tube is constricted and has a vent hole. An observation ball is disposed inside the observation tube and can slide freely within the observation tube. A conduit connector is fixedly connected to the end of the connecting pipe.

[0005] Preferably, the observation tube is a transparent tube that is thicker in the middle and thinner at both ends, the diameter of the observation ball is smaller than the inner diameter of the middle of the observation tube, and the diameter of the observation ball is larger than the inner diameter of the two ends of the observation tube.

[0006] Preferably, the grip shell is shaped like a handle, and includes a battery compartment and an air chamber inside the grip shell. The battery compartment contains a storage battery, and the air chamber contains an electric air pump. The electric air pump is electrically connected to the storage battery, and a switch is also electrically connected between the electric air pump and the storage battery. The switch is fixedly connected to the outside of the grip shell.

[0007] Preferably, the observation sphere is a hollow, lightweight sphere, and both the upper and lower ends of the observation tube are spherical cavities corresponding to the observation sphere.

[0008] Preferably, one end of the conduit connector is threaded to the connecting pipe, and the other end of the conduit connector is tapered.

[0009] Compared with the prior art, the advantages of this utility model are as follows: The starting mechanism of this utility model does not include a battery and a motor. The battery drives the motor to rotate, and a blower blade is fixedly connected to the output shaft of the motor. The motor drives the blower blade to rotate, enabling the blower blade to generate airflow. The entire motor and blower blade are housed in a relatively sealed motor compartment. When the motor rotates in the motor compartment, air is drawn in through the air inlet and exhausted into the connecting pipe. The airflow velocity in the connecting pipe increases. Due to Bernoulli's principle, the ball will be attracted to the bottom of the observation tube. When the conduit connector is connected to the pipe to be tested and the motor is turned on, if the high-speed gas generated during startup can flow out normally through the pipe to be tested, the connecting pipe will always maintain a low air pressure. During operation, the observation ball will be attracted to the bottom of the observation tube. If the pipe to be tested is blocked, preventing effective drainage, the air pressure in the connecting pipe will increase, thus lifting the observation ball to the top of the observation tube. The position of the observation ball can be used to determine the unobstructed flow of the pipe to be tested. Attached Figure Description

[0013] The following will describe specific embodiments and appendices. Figure 1-2 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0014] A convenient conduit patency / blockage detection device includes a pneumatic unit 1, a connecting pipe 2, an indicator 3, and a conduit connector 4. The pneumatic unit 1 generates gas with a certain pressure. The gas outlet of the pneumatic unit 1 is connected to the connecting pipe 2 and discharged through the connecting pipe 2. The end of the connecting pipe 2 is connected to the conduit to be tested. An indicator 3 is connected to the upper end of the connecting pipe 2. The indicator 3 can use Bernoulli's principle to show whether the pressure inside the connecting pipe 2 has changed, thereby indicating whether the conduit to be tested is blocked.

[0015] The pneumatic unit 1 includes a grip shell 11, which is shaped like a "7" for easy one-handed grip. The grip shell 11 contains a battery compartment 101 and an air chamber 102. The battery compartment 101 contains a battery 12, which powers the device without the need for a power supply line, making it convenient to use and operate. The air chamber 102 contains an air-generating device, which is an electric air pump 13. The electric air pump 13 is existing technology and is electrically connected to the battery 12. A switch is also electrically connected between the battery 12 and the electric air pump 13. The switch is fixedly connected to the outside of the grip shell 11, corresponding to the index finger position when gripping the device, making it easy to use. When the operator needs to open the device for testing, they only need to touch the switch with the index finger of the gripping hand to open it. The air chamber 102 is a relatively sealed space, and several air inlets are opened on the side of the air chamber 102 to allow the electric air pump 13 to absorb air.

[0016] A connecting pipe 2 is fixedly connected to the end of the pneumatic unit 1. The connecting pipe 2 is connected to the output end of the electric air pump 13 in the pneumatic unit 1. The high-speed gas generated by the electric air pump 13 will be discharged into the connecting pipe 2.

[0017] The top end of the connecting tube 2 is fixedly connected to an indicator part 3. The indicator part 3 includes an observation tube 31 and an observation ball 32. The observation ball 32 is slidably connected inside the replacement tube. The observation tube 31 is a transparent tube with open ends. The lower end of the observation tube 31 is connected to the connecting tube 2, and the upper end of the observation tube 31 has a vent hole 33. The diameter of the observation ball 32 is slightly smaller than the inner diameter of the middle part of the observation tube 31. The two ends of the observation tube 31 are constricted. The observation tube 31 is sinusoidal in shape, thicker in the middle and thinner at both ends. The constriction at both ends allows the observation ball 32 to slide up and down inside the observation tube 31. The upper and lower ends inside the observation tube 31 are connected to the observation ball 32. The spherical cavity corresponding to 2 allows the observation tube 31 to be completely sealed when the observation ball 32 is in contact with the spherical cavity. The observation ball 32 is a hollow, lightweight ball that can float due to airflow. When there is positive pressure inside the connecting tube 2, air will flow into the observation tube 31, lifting the observation ball 32 upwards, eventually causing the observation ball 32 to suspend or remain at the top of the observation tube 31. When there is negative pressure inside the connecting tube 2, the connecting tube 2 will draw air from the observation tube 31, thereby adsorbing the observation ball 32 to the lower part of the observation tube 31. The position of the observation ball 32 during the operation of this device can be used to make corresponding judgments.

[0018] A conduit connector 4 is fixedly connected to the end of the connecting pipe 2. The connecting pipe 2 and the conduit connector 4 are connected by threads. The other end of the conduit connector 4 is a tapered connector 41, which allows the conduit connector 4 to be nested on conduits of different diameters. The conduit connector 4 is made of rubber. When the wide-mouth conduit connector 4 is inserted into the conduit, it can be tightly connected to the conduit by squeezing it, which can achieve a temporary sealing connection for unobstructed testing. The tapered design increases the applicability of this utility model.

[0019] When using this invention, the holding shell 11 needs to be held firmly, and then the conduit connector 4 should be aligned with the conduit. The tapered connector 41 easily gets stuck on the round conduit. Then, the switch is turned on, connecting the battery 12 to the electric air pump 13. The electric air pump 13 begins to deliver high-speed gas into the connecting pipe 2. The high-speed gas flows from the connecting pipe 2 to the conduit to be tested. If the conduit to be tested is not blocked, the high-speed gas easily flows out of the conduit. At this time, the observation ball 32 is located below the observation tube 31. Since the high-speed gas passes through the connecting pipe 2 at high speed, according to Bernoulli's principle, the pressure is low at the location of high flow velocity. The connecting pipe 2 is located below the observation ball 32. The air velocity inside connector 2 is high, while the air velocity above the observation ball 32 is low, and the pressure is normal atmospheric pressure. Therefore, the ball will be subjected to downward pressure, and at the same time, the ball will be subjected to gravity, keeping it at the bottom of the observation tube 31. If the test tube is blocked, the high-speed gas discharged by the electric air pump 13 cannot flow out normally through the connecting tube 2 and the test tube, which will cause the pressure inside the connecting tube 2 to rise. The air inside the connecting tube 2 will rush into the observation tube 31 and flow out through the vent 33 at the top of the observation tube 31. At the same time, the observation ball 32 in the observation tube 31 will float with the airflow. By observing the position of the observation ball 32 during use, the patency of the test tube can be determined.

[0020] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0021] In this utility model, "upper", "lower", "left", "right", "front" and "back" are relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0022] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
