DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1-Figure 6 The present invention is a water level monitoring device for urban underground pipelines, comprising:

[0053] An intermediate column 1, which is coaxially arranged with the pipeline to be tested and is used to carry other components;

[0054] A plurality of support components are evenly distributed around the middle column 1;

[0055] The support components include:

[0056] An adjustment component is arranged on the middle column 1;

[0057] An adjustment plate 2, the adjustment plate 2 is installed on the output end of the adjustment component;

[0058] Two sliders 3, both sliders 3 are elastically slidably mounted on the adjustment plate 2;

[0059] An elastic member 4, both ends of which are fixedly connected to the two sliders 3 respectively. The elastic member 4 is a material that can undergo elastic deformation, and can be silicone, polyurethane, nitrile rubber, etc.;

[0060] When the elastic member 1 4 is pressed against the inner wall of the pipe to be tested, the two sliders 3 are driven to move in opposite directions;

[0061] It also includes a driving component, which is used to drive all the adjustment components to perform synchronous actions;

[0062] It also includes a radar level meter 5, which is installed on the adjustment plate 2 at the top;

[0063] The specific working process of the present invention is as follows: the driving component is started to drive all the adjustment components to perform synchronous actions. The adjustment component pushes the adjustment plate 2 to expand outward, so that the two sliders 3 and the elastic member 4 on the adjustment plate 2 gradually approach the inner wall of the pipe. When the elastic member 4 contacts the inner wall of the pipe, the elastic member 4 is compressed under the action of pressure to generate an elastic force. The elastic member 4 generates a reverse thrust during the compression process, so that the two sliders 3 move in the opposite direction, thereby ensuring that the elastic member 4 maintains close contact with the inner wall of the pipe. This elastic design enables the elastic member 4 to automatically adapt to pipes of different inner diameters, maintain a good contact area, and ensure the fixation and stability of the device in the pipe. After the installation is completed, the radar level meter 5 is installed on the adjustment plate 2 at the top, and the water level in the pipe is measured by the radar level meter 5. The radar level meter 5 transmits the measurement data to the external monitoring system to achieve real-time monitoring and data recording.

[0064] In order to make the slider 3 slide more smoothly and the elastic member 1 4 can return to its original state when the elastic member 1 4 is not under pressure, the present invention is further improved in that the support assembly further includes:

[0065] Two support plates 6 are fixed on both sides of the adjustment plate 2;

[0066] There are at least two optical axes 7, both ends of which are fixedly connected to two support plates 6, and two sliders 3 are slidably connected to the optical axes 7;

[0067] Elastic members 2 8, at least two in number, one end of the elastic member 2 8 is connected to the support plate 6, and the other end of the elastic member 2 8 is connected to the slider 3;

[0068] There are two limit blocks 9, both of which are fixedly connected to the adjustment plate 2;

[0069] Wherein, under the elastic force of the elastic member, the two limit blocks 9 are respectively in contact with the two sliders 3;

[0070] The specific working process of the support component is as follows: Figure 2 As shown, under the elastic force of the elastic member 2 8, the slider 3 contacts the limit block 9. When the elastic member 1 4 is subjected to pressure, the two sliders 3 are pushed to move in opposite directions along the optical axis 7. During this process, the elastic member 2 8 is compressed. When the elastic member 1 4 is not subjected to pressure, under the elastic force of the elastic member 2 8, the slider 3 contacts the limit block 9 again, and the elastic member 1 4 also returns to its initial state.

[0071] In order to keep the support member in position and prevent it from being dislocated when it is subjected to pressure or when the pressure disappears, the present invention is further improved in that the support assembly further includes:

[0072] The center rod 10 is rotatably mounted in the middle of the center rod 10 on the adjustment plate 2, and driving shafts 11 are fixed at both ends of the center rod 10. Figure 5 and Figure 6 As shown, the center rod 10 is inclined;

[0073] The bottom ends of the two sliders 3 are provided with long grooves, and the two driving shafts 11 extend into the two long grooves respectively;

[0074] When the elastic member 4 is subjected to pressure to drive the two sliders 3 to move to both sides, since the middle part of the center rod 10 is rotatably installed on the adjustment plate 2, the driving shafts 11 at both ends of the center rod 10 extend into the two long grooves respectively, and the length of the center rod 10 remains fixed. During the sliding process of the two sliders 3, it can ensure that the moving distances of the two sliders 3 are consistent and no misalignment occurs.

[0075] The conventional telescopic mechanism itself occupies a relatively large size. In order to accommodate more pipes, the present invention is further improved in that the adjustment component includes:

[0076] There are two telescopic components, and the two telescopic components move on different vertical planes;

[0077] The telescopic components include:

[0078] A rotating shaft 12 is rotatably mounted on the middle column 1;

[0079] A rotating rod 13, one end of which is fixedly connected to the rotating shaft 12;

[0080] A second rotating rod 14, one end of the second rotating rod 14 is rotatably connected to the other end of the first rotating rod 13 to form a V-shaped structure, and the other end of the second rotating rod 14 is rotatably connected to the adjustment plate 2;

[0081] The specific working process of the adjustment component is as follows: since there are two telescopic components, the two telescopic components operate on different vertical planes, so the adjustment plate 2 can only move radially along the middle column 1 under the action of the two telescopic components. When the distance of the adjustment plate 2 needs to be adjusted, the driving component is operated to make all the rotating shafts 12 rotate in the same direction, thereby driving the rotating rod 13 fixedly connected to the rotating shaft 12 to rotate. Since one end of the rotating rod 14 is rotatably connected to the other end of the rotating rod 13 to form a V-shaped structure, and the other end of the rotating rod 14 is rotatably connected to the adjustment plate 2, when the rotating shaft 12 rotates, the distance between each adjustment plate 2 and the middle column 1 changes. In this process, the angle formed by the rotating rod 13 and the rotating rod 2 14 also changes.

[0082] If the rotating shaft 12 is not synchronized, the intermediate column 1 cannot be adjusted to a position coaxial with the pipeline. Further, the present invention is improved in that the driving assembly includes:

[0083] The disc 15 is coaxially rotatably mounted on the middle column 1;

[0084] A plurality of connecting rods 16, each connecting rod 16 corresponds to a rotating shaft 12 in a telescopic assembly, the connecting rod 16 is fixedly connected to the rotating shaft 12, and the connecting rod 16 is provided with a strip hole along its length direction;

[0085] A plurality of fixed shafts 17, each fixed shaft 17 corresponds to a strip hole, and the fixed shaft 17 passes through the strip hole;

[0086] The specific working process of the driving assembly is as follows: when the adjustment assembly needs to be activated, the disc 15 is rotated to drive the fixed shaft 17 fixedly connected to the disc 15 to rotate. Since the fixed shaft 17 passes through the bar hole on the connecting rod 16, and the connecting rod 16 is fixedly connected to a rotating shaft 12 in the telescopic assembly, the fixed shaft 17 can push the connecting rod 16 and the rotating shaft 12 to rotate around the axis of the rotating shaft 12 when rotating, thereby driving all the rotating shafts 12 to rotate in the same direction, making the movement of each adjustment plate 2 consistent, thereby improving the convenience of use.

[0087] If the disc 15 does not use a locking device, it is easy to become loose after long-term use. Further, the present invention is improved in that the drive assembly also includes:

[0088] The worm gear 18 is coaxially fixed on the disc 15;

[0089] The worm 19 is rotatably mounted on the intermediate column 1, and the worm wheel 18 is meshed with the worm 19;

[0090] When the disc 15 needs to rotate, the rotating worm 19 drives the worm wheel 18 to rotate. Since the worm wheel 18 is fixedly connected to the disc 15, the disc 15 is driven to rotate. Since the worm wheel 18 and the worm 19 are used, the meshing of the worm wheel 18 and the worm 19 has a self-locking effect, which means that when the worm 19 stops rotating, the worm wheel 18 cannot rotate by itself. This self-locking feature ensures that the disc 15 will not loosen due to external interference after it stops rotating, thereby improving the stability and reliability of the device.

[0091] In order to facilitate the rotation of the worm 19, the present invention is further improved in that an operating part is provided at the end of the worm 19. The operating part can be a hand wheel or a hexagonal groove opened at the end of the worm 19, which can conveniently rotate the worm 19, thereby driving the rotation of the worm wheel 18 and the disc 15, ensuring that the intermediate column 1 can be aligned with the coaxial line position of the pipeline, thereby improving the convenience of operation.

[0092] If the middle column 1 directly faces the flowing water, the middle column 1 will be subjected to a greater impact force. Furthermore, the present invention has an improvement in that a conical section 20 is provided on one side of the middle column 1. The design of the conical section 20 enables the water flow to bypass the middle column 1 more smoothly, reducing the force of the water flow directly impacting the middle column 1. At the same time, the conical section 20 can effectively disperse the impact force of the water flow, reduce the direct pressure of the water flow on the middle column 1, and thus protect the middle column 1 from damage.

[0093] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
