Description

Technical Field

[0001] This utility model belongs to the field of pipeline water flow detection technology, specifically relating to a drainage pipeline water flow detection device. Background Technology

[0002] Drainage systems are a vital part of urban infrastructure, playing a crucial role in urban economic development. By detecting the flow velocity of water inside drainage pipes using monitoring devices, data analysis can reveal potential problems such as blockages and leaks within the drainage system.

[0003] Existing detection methods typically involve opening the manhole cover at the vertical shaft and lowering a detection component into the shaft to probe the drainage pipe. Related prior art, such as Chinese Patent No. CN108265816B, discloses an installation auxiliary device for pipe detection equipment. This device uses a fixed-size ring bracket to install and position the detection component, ensuring its stable placement within the vertical shaft for water flow detection in the drainage pipe.

[0004] However, in actual use, due to different regions and different needs, the corresponding shaft opening sizes are not the same (the commonly used standard opening diameters are 0.8 meters, 1.0 meters, and 1.2 meters). The fixed-size ring bracket cannot be used for shafts with different opening diameters. As a result, the detection components need to be equipped with many different types of auxiliary installation devices during installation. That is, the existing auxiliary installation devices are difficult to adapt to shafts with different diameters, which increases the difficulty of carrying, transporting and storing, as well as increasing the detection cost. Utility Model Content

[0005] The present invention aims to provide a drainage pipe water flow detection device to solve the problem mentioned above that the existing auxiliary installation devices are difficult to adapt to vertical shafts of different diameters.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage pipe water flow detection device, installed in a vertical shaft, comprising...

[0007] There are two support rods arranged horizontally, which are movably connected and distributed vertically. Universal wheels are installed at both ends of the support rods.

[0008] The control unit is installed on the support rod. The control unit includes a clamp plate and a control component. Two clamp plates are symmetrically installed on the support rod. The control component is used to control the distance between the two clamp plates. The clamp plates can abut against the wall of the shaft.

[0009] Limiting components are used to limit the position between the two rods;

[0010] The detection unit includes a detector, a sliding sleeve, and an extension rod assembly. The sliding sleeve is slidably fitted onto the support rod, the extension rod assembly is detachably installed outside the sliding sleeve, and the detector is installed at the bottom of the extension rod assembly.

[0011] The principle and effects of this technical solution:

[0012] 1. The position of the two clamping plates relative to the support rod is controlled by the control component, so that the clamping plates can be adjusted to abut against the inner wall of different vertical shaft pipe diameters. The support rod can also be stably placed on the top of the vertical shaft or the ground through the casters. The casters can also be limited by the brake pads of the casters. Through the setting of this device, the detection device can be applied to different vertical shaft pipe diameters, thus expanding its application range.

[0013] 2. The extension rod assembly and detector are connected to the support rod via a sliding sleeve, allowing the detector and extension rod assembly to be stably installed on the support rod to monitor the water flow in the drainage pipes inside the shaft. Furthermore, the use of a limiting component ensures relative stability between the two support rods, while also reducing the overall space required by minimizing the included angle, facilitating transport and carrying.

[0014] 3. The omnidirectional wheels allow the detection unit to adjust its position relative to the drainage pipe by rotating the support rod, making position adjustment convenient and quick.

[0015] The present invention is further configured such that: a mounting base is rotatably installed on the top of the lower support rod, and a rotating sleeve is fixedly fitted on the upper support rod. The rotating sleeve is rotatably installed in the mounting base, and an anti-rotation bolt is threaded into the mounting base. An anti-rotation hole is opened on the outer wall of the rotating sleeve, and the end of the anti-rotation bolt can extend into the anti-rotation hole.

[0016] The principle and effect of this technical solution: By rotating the mounting base, the angle between the upper and lower support rods can be adjusted by rotation, achieving the effect of unfolding and storing. Through the setting of the rotating sleeve and mounting base, the upper support rod can be rotated 180 degrees relative to the lower support rod, so that the projection of the upper support rod on the horizontal plane completely overlaps with the lower support rod. At this time, the universal wheel on the upper support rod flips to the top without interference from the presence of the lower support rod, further reducing the space required for folding and storage, and making it easier to carry.

[0017] The present invention is further configured such that: the limiting component includes a first limiting plate, a second limiting plate and a limiting bolt, the first limiting plate is fixed to the outer wall of the mounting base, the second limiting plate is fixed to the side wall of the support rod located below, the top surface of the support rod located below and the top surface of the second limiting plate are both provided with limiting holes, the limiting bolt is threaded into the first limiting plate, and the end of the limiting bolt can be inserted into the limiting hole.

[0018] The principle and effect of this technical solution: By setting the first limiting plate, the limiting bolt can be installed on the outer wall of the mounting base. By inserting the outer wall of the limiting bolt into the second limiting plate and the limiting hole on the support rod below, a horizontal rotation limiting effect can be achieved, so that the two brackets can maintain a stable position when they are unfolded or retracted, with high stability and reliability.

[0019] The present invention is further configured such that: the control component includes a control head and a bidirectional screw; the support rod has two symmetrically opened sliding grooves; the clamping plate is slidably engaged with the sliding grooves; the bidirectional screw is rotatably installed inside the support rod and passes through the sliding grooves; the clamping plate is threadedly fitted onto the bidirectional screw; one end of the bidirectional screw extends outside the support rod and is fixed to the control head.

[0020] The principle and effect of this technical solution: The rotation of the bidirectional screw can simultaneously control the two clamps on a support rod to move closer or further apart, so that the distance between the outer walls of the two clamps can be adjusted according to the pipe diameter of the shaft opening, and the abutment between the clamps and the shaft wall prevents the support rod from shifting relative to the shaft during use.

[0021] The present invention is further configured such that: ball bearings are installed on the side wall of the clamping plate, and the ball bearings abut against the wall of the vertical shaft.

[0022] The principle and effect of this technical solution: By setting the ball bearings, the contact between the clamp and the well wall can be changed from sliding contact to rolling contact. When adjusting the position by rotation, the friction is smaller and more convenient.

[0023] The present invention is further configured such that: the extension rod assembly includes multiple rods connected end to end in sequence, the top of the rod has a connecting section, the bottom of the rod has a connecting hole, and the connecting section can be threadedly adapted to the connecting hole.

[0024] The principle and effect of this technical solution: By setting up multiple rods, the overall length of the extension rod assembly can be adjusted by adding or removing rods, thereby allowing the probe's insertion depth to be adjusted according to actual conditions, making it more versatile.

[0025] The present invention is further configured such that: the detection unit also includes a limiting sleeve, a sliding seat is installed on one side of the sliding sleeve, the rod body can be slidably inserted into the sliding seat, the limiting sleeve can be threaded onto the rod body, and the limiting sleeve abuts against the top surface of the sliding seat, and an anti-slip bolt is threadedly inserted on the other side of the sliding sleeve, the end of the anti-slip bolt can abut against the outer wall of the support rod.

[0026] The principle and effect of this technical solution: By setting the limiting sleeve and the slide, the upper end of the extension rod assembly can be threaded with the limiting sleeve. The extension rod assembly is hung on the slide by the abutment between the limiting sleeve and the slide, thereby limiting the position of the extension rod assembly and the detector. Then, by the anti-slip bolt abutting against the outer wall of the support rod, the sliding limiting effect can be achieved, which can ensure the position of the slide relative to the support rod to a certain extent.

[0046] Example:

[0047] As attached Figure 1-10 As shown, this utility model discloses a drainage pipe water flow detection device, installed in a vertical shaft 101, including support rods 201, a control unit, a limiting component, and a detection unit. There are two support rods 201, both horizontally oriented, vertically distributed and movably connected. Both ends of the two support rods 201 are equipped with casters 202. Due to the different bottom heights of the two support rods 201, the caster 202 corresponding to the higher support rod 201 has a longer rod length than the caster 202 corresponding to the lower support rod 201, ensuring that all four casters 202 can contact the ground or the top surface of the vertical shaft 101. See attached figure for details. Figure 3 As shown.

[0048] A mounting base 501 is rotatably mounted on the top of the middle section of the lower support rod 201 (i.e., the mounting base 501 can rotate horizontally relative to the support rod 201, specifically through a rotating shaft or other connecting parts). This arrangement allows the included angle between the projections of the two support rods 201 onto the horizontal plane to be adjusted by rotation. A rotating sleeve 502 is fitted and fixed in the middle of the upper support rod 201, and the rotating sleeve 502 is rotatably mounted within the mounting base 501. This arrangement allows the upper support rod 201 and its corresponding caster wheels to be rotatably mounted. 202, clamping plate 301, etc. can be rotated 180° so that when the projections of the two support rods 201 on the horizontal plane are completely overlapped, the clamping plate 301 and caster wheel 202 corresponding to the upper support rod 201 will not be interfered with by the presence of the lower support rod 201. The caster wheel 202 has a brake pad (not shown in the figure). The mounting base 501 is threaded with an anti-rotation bolt 503. The outer wall of the rotating sleeve 502 has two anti-rotation holes 504 symmetrically opened. The end of the anti-rotation bolt 503 can extend into the anti-rotation hole 504.

[0049] The limiting assembly includes a first limiting plate 601, a second limiting plate 602, and a limiting bolt 603. The first limiting plate 601 is fixed to the outer wall of the mounting base 501, and the second limiting plate 602 is fixed to the side wall of the lower support rod 201. Limiting holes 604 are provided on the top surface of both the lower support rod 201 and the top surface of the second limiting plate 602. The limiting bolt 603 is threaded into the first limiting plate 601, and its end can be inserted into the limiting hole 604. That is, when unfolded, the limiting bolt 603 can be inserted into the limiting hole 604 of the lower support rod 201; when retracted, the limiting bolt 603 can be inserted into the limiting hole 604 of the second limiting plate 602.

[0050] Each support rod 201 is equipped with a control unit, which includes a clamping plate 301 and a control component. Two clamping plates 301 are symmetrically installed on the support rod 201. The control component includes a control head 303 and a bidirectional screw 302. Two sliding grooves 203 are symmetrically opened on the support rod 201. The clamping plate 301 slides in the sliding groove 203. The bidirectional screw 302 is rotatably installed in the support rod 201 and passes through the sliding groove 203. The clamping plate 301 is threaded onto the bidirectional screw 302. One end of the bidirectional screw 302 extends to the outside of the support rod 201 and is fixed to the control head 303. A ball bearing 304 is installed on the side wall of the clamping plate 301. The ball bearing 304 abuts against the wall of the vertical shaft 101.

[0051] The detection unit includes a detector 401, a sliding sleeve 402, a limiting sleeve 404, a sliding base 403, and an extension rod assembly. The sliding sleeve 402 is slidably fitted onto the support rod 201 (as shown in the attached drawing; the sliding sleeve 402 is square-tube shaped, and its bottom has a clearance opening to allow space for the clamping plate 301). The extension rod assembly includes multiple rods 701 connected end-to-end. Each rod 701 has a connecting section 702 at its top and a connecting hole 703 at its bottom. The connecting section 702 is threaded into the connecting hole 703. The detector 401 is installed at the bottom of the extension rod assembly and can extend into the shaft 101. At the bottom of the lowest pole 701, the detector 401 is a water flow velocity detector. This is an existing product structure, and it can be equipped with a power supply or other components inside the pole 701 for extended operation. In this case, the pole 701 can be a hollow structure (although the attached diagram shows a solid structure, this is for reference only and not as a limitation. Appropriate sealing and waterproofing measures are required inside the pole 701 with the water flow velocity detector 401 installed; these are existing technologies and will only be briefly described here. The hollow design also reduces the device's weight, making it easier to carry, retrieve, and install). In use, the detector 401 can enter the bottom of the vertical shaft to detect the water flow in the horizontally placed drainage pipe.

[0052] A sliding block 403 is installed on one side of the sliding sleeve 402. The rod body 701 is slidably inserted into the sliding block 403. The limiting sleeve 404 is threaded onto the rod body 701 and abuts against the top surface of the sliding block 403. In use, after the number of rod bodies 701 is determined, the limiting sleeve 404 is installed on the upper rod body 701. Under the weight of the rod body 701, the limiting sleeve 404 is hooked onto the sliding block 403. An anti-slip bolt 405 is threaded into the other side of the sliding sleeve 402. The end of the anti-slip bolt 405 can abut against the outer wall of the support rod 201. The extension rod assembly is detachably installed outside the sliding sleeve 402. The detector 401 is installed at the bottom of the extension rod assembly and can extend into the vertical shaft 101.

[0053] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0054] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.

[0055] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
