[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 and Figure 2The utility model provides an embodiment: a concrete pumping pipeline blockage detection device, including a pipe body 1, a disc 3 is arranged at the left end of the pipe body 1, a movable rod 4 is arranged at the middle of the left side of the disc 3, the right end of the movable rod 4 passes through the disc 3 and is fixedly connected to a hollow frame 5, a micro motor 6 is fixedly connected to the inner bottom of the hollow frame 5, a worm 7 is fixedly connected to the output end of the micro motor 6, a rotating rod 8 is rotatably connected to the inside of the hollow frame 5, a semi-worm gear 9 is fixedly connected to the outer side of the rotating rod 8, the semi-worm gear 9 is meshed with the worm 7, and the right side of the semi-worm gear 9 A connecting rod 10 is fixedly connected, a cylinder 11 is fixedly connected to the right end of the connecting rod 10, a button 12 is fixedly connected to the output end of the cylinder 11, a buzzer alarm 16 is fixedly connected to the left end of the movable rod 4, the buzzer alarm 16 is electrically connected to the button 12, a protective frame 19 is arranged outside the buzzer alarm 16, one side of the protective frame 19 is fixedly connected to the left end of the movable rod 4, a clamping mechanism 2 is arranged inside the disc 3, scales 15 are provided on the front sides of the movable rod 4 and the cylinder 11, and the top end of the worm 7 is rotatably connected to the inner top of the hollow frame 5;

[0038] Specifically, the micro motor 6 can drive the worm 7 to rotate, and the worm 7 is meshed with the half worm gear 9. When the worm 7 rotates, the half worm gear 9 will also rotate. This rotation design cleverly realizes the up and down tilting function of the cylinder 11. The tilt angle of the cylinder 11 can be adjusted according to the shape of the pipeline to be detected, so that it can adapt to pipelines of different shapes. At this time, the cylinder 11 can drive the button 12 to move inside the pumping pipeline. The design of this button 12 is very unique. It has a certain elasticity and can be squeezed when it contacts the blocked part. Once the button 12 is squeezed, it will immediately start the buzzer alarm 16. This buzzer alarm 16 uses a highly sensitive sound sensor, which can emit a loud alarm in a very short time to remind the staff of the blocked position. This design allows the staff to quickly locate the blocked part and carry out maintenance in time.

[0039] Reference Figure 1 and Figure 3 The clamping mechanism 2 includes a through-mouth groove 201, which is opened on one side of the disc 3. The top of the disc 3 is rotatably connected with a bidirectional screw rod 202, the middle and lower parts of the bidirectional screw rod 202 pass through the through-mouth groove 201, and the upper and lower sides of the outer wall of the bidirectional screw rod 202 are both threadedly connected with movable blocks 203. Both movable blocks 203 are slidably connected to the inside of the through-mouth groove 201, and the right side of the movable block 203 is fixedly connected with an arc-shaped clamping plate 204;

[0040] Specifically, by rotating the bidirectional screw rod 202, the movable blocks 203 on both sides can be driven to move toward the middle. This design cleverly utilizes the mechanical principle, so that the arc-shaped clamping plate 204 can move accordingly, and the pipeline can be accurately limited and clamped. This limited clamping design is not only simple and easy to implement, but also very effective. It can ensure that the detection device is firmly fixed on the pumping pipeline, avoiding shaking or falling off that may occur during the detection process. This stability is crucial to ensure the accuracy of the test results, thereby facilitating the subsequent detection work of the staff.

[0041] Reference Figure 2 The right side of the button 12 is fixedly connected with a T-shaped rod 13, and a spring 14 is arranged on the outside of the T-shaped rod 13, one end of the spring 14 is fixedly connected with the left side of the T-shaped rod 13, and the other end of the spring 14 is fixedly connected with the right side of the button 12;

[0042] Specifically, the elastic potential energy of the spring 14 can drive the button 12 to rebound, thereby controlling the operation of the buzzer alarm 16 .

[0043] Reference Figure 1 and Figure 2 A switch 17 is fixedly connected to the top of the movable rod 4, and the switch 17 is electrically connected to the micro motor 6 and the cylinder 11 respectively. A protective cover 18 is provided on the outside of the switch 17, and one side of the protective cover 18 is rotatably connected to the top of the movable rod 4;

[0044] Specifically, the operation of the micro motor 6 and the cylinder 11 can be controlled by the switch 17, and the protective cover 18 can protect the switch 17 from being damaged by external factors.

[0045] Reference Figure 3 The clamping mechanism 2 further includes a rubber pad 205, and two rubber pads 205 are respectively fixedly connected to one side of the corresponding arc-shaped clamping plate 204;

[0046] Specifically, the friction between the tube body 1 and the arc-shaped clamping plate 204 can be further improved by the rubber pad 205, so that the detection device can be placed more stably.

[0047] Working principle: When using the device, first carry the detection device to the pumping pipe to be detected, and then insert one end of the button 12 into the pumping pipe. At this time, the cylinder 11 can drive the button 12 to move inside the pumping pipe until it touches the blocked part. At this time, the button 12 is squeezed to activate the buzzer alarm 16, and the buzzer alarm 16 will make a sound to remind the staff of the blockage position. Then the detection personnel determine the depth of the blockage position of the pumping pipe through the movable rod 4 and the scale 15 on the surface of the cylinder 11, so as to facilitate the fixed-point cleaning, which is simple, fast and accurate. After taking out the detection device, the spring 14 will release the squeezed potential energy and drive the button 12 to rebound to its original state to turn off the buzzer alarm 16. When the bent pumping pipe needs to be cleaned, the detection personnel will use the scale 15 on the surface of the movable rod 4 and the cylinder 11 to detect the blockage position. When the pipeline is to be inspected, the micro motor 6 can drive the worm 7 to rotate, and the half worm wheel 9 will also rotate due to the meshing with the worm 7, thereby driving the cylinder 11 to tilt up and down. At this time, the use angle of the button 12 can be adjusted according to the shape of the pipeline to be inspected, so that it can detect pipelines of different shapes, thereby improving the practicality of the device and meeting the needs of users. When using the detection device, first place the disc 3 on the left end of the pipe body 1, and then rotate the bidirectional screw 202 to drive the movable blocks 203 on both sides to move toward the middle, and the arc clamping plate 204 will move accordingly to limit the clamping of the pipeline, so that the detection device can be conveniently fixed on the pumping pipeline, thereby facilitating the subsequent detection work of the staff.
