Description

Technical Field

[0001] This invention relates to the field of conduit blockage detection technology, specifically to a conduit blockage detection device. Background Technology

[0002] Currently, during construction, within 24 hours of concrete formwork removal, exposed conduit openings are cleaned, and the conduit is cut flat (leaving 5cm under the slab and 2cm above ground). Any deformation or damage to the conduit openings is checked and marked. A Φ2.5mm steel wire or a special wire threader (with a rotating head) is used to test for blockage from both ends in both directions, recording the depth when obstruction is encountered; alternatively, manual air blowing can be used for initial blockage detection. However, these methods suffer from low testing efficiency and cumbersome operation. Utility Model Content

[0003] This invention discloses a conduit blockage detection device, the purpose of which is to improve the efficiency of conduit blockage detection and quickly determine the degree of conduit blockage.

[0004] To achieve the above objectives, the technical solution of this invention is as follows: A conduit blockage detection device includes a blower, a sleeve, a conduit connector, and a wind pressure detection device. The sleeve is fixedly connected to one end of the blower body, and the blower's air outlet extends into the sleeve. A conduit connector is connected to the end of the sleeve away from the blower. The wind pressure detection device is installed on the sleeve, and the conduit connector is used to connect to the port of the conduit to be tested.

[0005] Preferably, the sleeve has a circular tube section, one end of which gradually narrows in diameter and is fixedly connected to the conduit connector at the port, and the other end of which is sealed and fixedly connected to the housing of the blower. The air outlet pipe is coaxially arranged with the circular tube section.

[0006] Preferably, the conduit connector is a stepped tube, with the larger diameter end of the stepped tube threadedly connected to the end of the sleeve away from the blower, and the smaller diameter end fitting into the inner hole of the conduit to be tested.

[0008] Preferably, the conduit connector is available in several models based on the difference in the outer diameter of the smaller diameter end.

[0009] Preferably, the annular end face with the larger diameter end facing the smaller diameter end is further provided with an annular rubber gasket for sealing the port of the conduit to be tested.

[0010] Preferably, the wind pressure detection device is an air pressure gauge connected to the circular pipe section. The air pressure gauge is connected to the circular pipe section through a connecting pipe. The air inlet of the connecting pipe is offset from the air outlet of the air outlet pipe. The air inlet is located on the side of the air outlet away from the conduit joint.

[0011] Preferably, the wind pressure detection device includes an annular piston arranged around the air outlet pipe. The outer and inner surfaces of the annular piston are respectively damped and slidably connected to the inner wall of the circular pipe section and the outer wall of the air outlet pipe. A spring is also sleeved on the air outlet pipe. An annular pressure sensor is sleeved on one end of the air outlet pipe that is connected to the blower housing.

[0016] The following is a detailed description of the embodiments of the present invention in a step-by-step manner. This description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0017] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this invention.

[0018] Example 1: A conduit blockage detection device, such as Figure 1 , 4 As shown, the device includes a hair dryer 1, a sleeve 4, a conduit connector 5, and a wind pressure detection device. The sleeve 4 is fixedly connected to one end of the hair dryer 1. The air outlet pipe 3 of the hair dryer 1 extends into the sleeve 4. The conduit connector 5 is connected to the end of the sleeve 4 furthest from the hair dryer 1. A wind pressure detection device is installed on the sleeve 4. The conduit connector 5 is used to connect to the conduit port to be tested. When the hair dryer 1 is started, if there is a blockage inside the conduit, the wind pressure will rise. The degree of blockage is determined by the magnitude of the wind pressure increase. When there is no blockage inside the conduit, the wind pressure remains stable within a certain range.

[0019] Example 2: like Figure 1 , 4 As shown, the sleeve 4 is provided with a circular tube section 41. One end of the circular tube section 41 gradually narrows in diameter and is fixedly connected to the conduit connector 5 at the port. The other end of the circular tube section 41 is sealed and fixedly connected to the housing 2 of the blower. The air outlet pipe 3 is coaxially arranged with the circular tube section 41.

[0020] like Figure 1-4 As shown, the conduit connector 5 is a stepped tube. The larger diameter end 51 of the stepped tube is threaded to the end of the sleeve 4 away from the blower 1, and the smaller diameter end 52 is fitted with the inner hole of the conduit 7 to be tested.

[0021] like Figure 3 As shown, the outer diameter of the small-diameter end 52 is the same as the inner diameter of the tube 7 to be tested.

[0022] like Figure 1-4 As shown, the conduit connector 5 has several models based on the difference in the outer diameter of the smaller diameter end 52.

[0023] In this embodiment, when performing conduit testing, a conduit connector 5 with a suitable inner diameter is selected, and after connecting it to the sleeve thread, the smaller diameter end 52 is inserted into the conduit port, and the blower is started for testing.

[0024] Example 3: like Figure 2 , 3 As shown, an annular rubber gasket 53 is also provided on the annular end face of the larger diameter end 51 facing the smaller diameter end 52 for sealing the port of the tube 7 to be tested. After the smaller diameter end is inserted into the tube, the annular rubber gasket presses against the tube port to achieve a seal, preventing air leakage from the port from affecting the air pressure detection effect.

[0025] Example 4: Based on embodiments 1-3, the wind pressure detection device is an air pressure gauge 6 connected to the circular pipe section 41. The air pressure gauge 6 is connected to the circular pipe section 41 through a connecting pipe. The air inlet of the connecting pipe is staggered from the air outlet of the air outlet 3 to avoid the influence of air blowing from the air outlet on the air pressure gauge. The air inlet is located on the side of the air outlet away from the conduit connector 5.

[0026] Example 5: Based on embodiments 1-3, the wind pressure detection device includes an annular piston 8 arranged around the air outlet pipe 3. The outer and inner surfaces of the annular piston 8 are respectively damped and slidably connected to the inner wall of the circular pipe section 41 and the outer wall of the air outlet pipe 3 (this effect can be achieved by setting an elastic rubber layer on the inner and outer surfaces of the annular piston). A spring 9 is also sleeved on the air outlet pipe 3. An annular pressure sensor 10 is sleeved on one end of the air outlet pipe 3 connected to the blower housing. The annular pressure sensor 10 is fixedly connected to the housing. One end of the spring 9 is connected to one end of the annular piston 8 through a first spring seat (a common device, not shown in the figure). The other end of the spring 9 is connected to the annular pressure sensor 10 through a second spring seat. The annular pressure sensor 10 is connected to a display (not shown in the figure) through a wire. The display is fixedly mounted on the outer surface of the housing.

[0027] During testing, air is blown into the conduit through the conduit connector. When the conduit becomes blocked, the air pressure rises, pushing the annular piston away from the conduit connector. This compresses the spring, causing the annular pressure sensor to detect an increase in the reading. The degree of blockage is determined based on the magnitude of the increase in the reading.

[0028] As described above, this invention provides two wind pressure detection devices, Embodiments 4 and 5.

[0029] Example 6: Based on the above embodiments, this embodiment discloses that: since most of the pipes on the construction site are 20 or 25 gauge, a handheld high-volume blower with a 110,000 RPM motor and a wind speed of 65 m / s is selected to further improve the detection efficiency of pipe blockage.
