[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1, by Figure 1 The present invention relates to a water supply pipe leak detection device, including a pipe body 1, the number of which is two, the two pipe bodies 1 are fixed by a flange, and a leak detection mechanism 2 is provided below the connection between the two pipe bodies 1.

[0026] Specifically, by Figure 2-5The leak detection mechanism 2 includes a positive bucket 201, with a negative bucket 202 located at the center of its inner side. The negative bucket 202 is positioned directly below the connection between the two pipe bodies 1. Two guide rods 2010 are symmetrically and fixedly connected between the positive bucket 201 and the negative bucket 202. Guide rings 2014 are movably sleeved on the outer sides of each guide rod 2010. Connecting round rods 2015 are fixedly connected to the outer sides of each guide ring 2014. A float plate is fixedly connected between the two connecting round rods 2015. 204. A float plate 204 is located between the inverted bucket 202 and the upright bucket 201, and is positioned between two guide rods 2010. A pressure rod 2012 is fixedly connected to the top of the float plate 204. A pressure sensor 2013 is fixedly installed on the inner top wall of the inverted bucket 202, directly above the pressure rod 2012. A mounting base 207 is fixedly installed on the outer side of the upright bucket 201. An alarm 208 and a controller 209 are located on the outer side of the mounting base 207. Device 2013 is electrically connected to controller 209, and controller 209 is electrically connected to alarm 208. A drain pipe 205 is fixedly connected to the bottom of the bucket 201. A valve 206 is installed on the drain pipe 205, which can be opened to allow water in the bucket 201 to drain out. An annular groove 2016 is provided on the inner side of guide ring 2014. Multiple balls 2017, each abutting against the outer wall of guide rod 2010, are provided at equal angles on the inner side of the annular groove 2016. The ball bearing 2017 prevents the guide ring 2014 from directly contacting the guide rod 2010, reducing the friction force on the guide ring 2014 when it slides on the outside of the guide rod 2010, thus facilitating the smooth raising and lowering of the float 204. Two support rods 2011 are symmetrically fixedly connected to the bottom of the bucket 202. The ends of the two support rods 2011 away from the bucket 202 abut against the bottom of the float 204. By setting the two support rods 2011, the float 204 can be supported.

[0027] In operation, when leakage occurs at the connection between the two pipe bodies 1, water flows into the main bucket 201 through the guiding effect of the inverted bucket 202. When the water level in the main bucket 201 rises, it pushes the float 204 upward. Through the two connecting round rods 2015, the two guide rings 2014 slide upward along the two guide rods 2010 respectively. At the same time, the pressure rod 2012 rises. When the pressure rod 2012 squeezes the pressure sensor 2013, the pressure sensor 2013 transmits an electrical signal to the controller 209. The controller 209 controls the alarm 208 to start the alarm, so that the staff can discover and deal with it in time during the inspection.

[0028] Specifically, by Figure 6As shown, the top of the bucket 201 is symmetrically fixedly connected to two columns 2020, the top of each column 2020 is fixedly connected to a top plate 2019, the outer sides of each of the two tube bodies 1 are fixedly sleeved with collars 203, the bottom of each collar 203 is fixedly connected to a bottom plate 2018, the two bottom plates 2018 abut against the two top plates 2019 respectively, bolts 2021 are installed between the bottom plates 2018 and the top plates 2019, a positioning rod 2022 is fixedly connected to the outer side of the bottom plate 2018, and the top plate 2019 is sleeved on the outer side of the positioning rod 2022;

[0029] In use, first, the two top plates 2019 are respectively placed on the outside of the two positioning rods 2022, so that the two top plates 2019 abut against the two bottom plates 2018 respectively. Then, the two top plates 2019 are fixed to the two bottom plates 2018 respectively by two bolts 2021, thereby fixing the two columns 2020 to the two collars 203 respectively. Finally, the installation and fixing of the bucket 201 is completed.
