Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of municipal inspection wells, in particular to an anti-leakage municipal inspection well. Background Art
[0002] Inspection wells are set up for the convenience of maintenance and installation of urban underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines. They are generally located at pipeline intersections, bends, places where pipe diameters or slopes change, and at certain intervals on straight pipe sections. In order to facilitate regular inspections, cleaning, dredging, or downhole operations, inspection wells are generally made of one-piece plastic injection molding or brick-built well-shaped structures.
[0003] The Chinese utility model patent with application number: 202322163422.8 discloses a leakage-proof safe municipal inspection well, including an inspection well and an anti-leakage mechanism. The anti-leakage mechanism is installed on both sides of the inspection well, and a manhole cover is movably connected to the top of the inspection well. Through the anti-leakage mechanism, the pipeline is moved through the pipeline mouth to a suitable position, and the semicircular ring plate is flipped, and the lock buckle is driven to move at the same time, so that the lock buckle enters the locking slot. When the lock buckle contacts the pressure block, the pressure block continues to move. At the same time, the pressure block drives the movable plate and the slider to move, and the pressure block is restored to its original position through the elastic force of the spring. At the same time, the pressure block drives the slider to enter the circular slot, and the switch button of the water leakage alarm is pressed to make the water leakage alarm work normally. When water seepage occurs, the alarm will sound an alarm, and the user can inspect the water seepage place in time. Through the setting of the locking component, the user greatly reduces the possibility of the inspection well and the pipeline being separated when in use.
[0004] However, during the use of existing municipal inspection wells, the sealing sleeves gradually age and wear over time, resulting in an increasingly larger gap between the delivery pipe and the sealing sleeve, causing leakage between the delivery pipe and the sealing sleeve. The existing inspection well locking components cannot flexibly adjust the locking force between the pipeline and the inspection well, thereby compensating for the gap caused by the aging of the sealing sleeve; moreover, the existing municipal inspection wells do not have insulation devices and are easily frozen and cracked in cold places, resulting in leakage in the inspection well body.

The outer wall surface of the inspection well body 1 is provided with a main body leakage-proof structure, and the inner wall surface of the pipe connecting pipe 3 is provided with a pipe leakage-proof structure. The outer wall surface of the pipe connecting pipe 3 is provided with a plurality of guide grooves 4, and pipe locking structures are installed in the plurality of guide grooves 4, and the outer wall surface of the pipe connecting pipe 3 is provided with threads.
[0023] like Figure 1-2 As shown, the main body anti-leakage structure includes: a heat-conducting sleeve 5, a heating wire 6 and a plurality of temperature sensors 7;
[0024] The heat-conducting sleeve 5 is sleeved on the outer wall surface of the inspection well body 1 , the heating wire 6 is sleeved on the outer wall surface of the heat-conducting sleeve 5 , and a plurality of temperature sensors 7 are evenly installed on the inner wall surface of the inspection well body 1 .
[0025] When several temperature sensors 7 detect that the temperature is lower than the set value, the heating wire 6 starts to heat the thermal sleeve 5. The thermal sleeve 5 makes the inspection well body 1 heated more evenly. Until several temperature sensors 7 detect that the temperature is higher than the set value and reaches the temperature in the constant temperature zone, the heating wire 6 is turned off. This cycle is repeated to ensure that the inspection well body 1 always maintains the optimal temperature and prevents the inspection well body 1 from being frozen and cracked. The thermal sleeve 5 is made of thermally conductive metal material to improve heat transfer efficiency.

[0027] The pipeline locking structure includes: a plurality of rotating shafts 11, a plurality of connecting frames 12, and a plurality of locking blocks 13; the plurality of rotating shafts 11 are respectively installed on the inner wall surfaces of a plurality of guide grooves 4, each rotating shaft 11 is correspondingly rotatably connected with a connecting frame 12, a locking block 13 is arranged at one end of the connecting frame 12 away from the rotating shaft 11, and a clamping inclined surface is arranged at one end of the connecting frame 12 close to the threaded sleeve 10.

At the same time, the plurality of connecting frames 12 respectively drive the plurality of locking blocks 13 to lock the sealing sleeve 9 on the conveying pipe 8.
