Description

Technical Field

[0001] This utility model relates to the field of smart water meter technology, and specifically to a smart water meter with a telescopic structure. Background Technology

[0002] A smart water meter is a new type of water meter that combines modern electronic technology with the traditional water meter measurement principle. Its measurement principle is mainly based on the combination of mechanical measurement and electronic sensing technology. The traditional mechanical water meter part uses water flow to drive the impeller to rotate. The speed of the impeller is proportional to the speed of the water flow, thereby realizing the measurement of water volume. In a smart water meter, a sensor is added to collect the rotation information of the impeller, such as a Hall sensor.

[0003] Most smart water meters do not have antifreeze features, so many meters remain exposed to the elements in cold weather, making the water inside prone to freezing and preventing users from using water.

[0004] The prior art proposes a Chinese patent with publication number CN214748222U to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A smart water meter, belonging to the field of smart water meter technology. It includes a meter casing, a water inlet, and a water outlet; one end of the water inlet has a water inlet pipe, one end of the water inlet pipe has a first flared opening, and one end of the water inlet has a second flared opening, with a lightweight ball inside the second flared opening. A valve is installed inside the water inlet. A water meter support frame is installed inside the meter casing, and a first spring is installed between the meter casing and the water meter support frame. An impeller and a suction tube are installed inside the water meter support frame. A pressing device is installed on the meter casing, connected to the suction tube. The meter casing also includes a power module, a valve drive module, a wireless data module, a storage module, a monitoring module, and an MCU main control unit. The power module, valve drive module, wireless data module, storage module, and monitoring module are all electrically connected to the MCU main control unit. This utility model provides a smart water meter that can upload water meter data to the management system, thereby eliminating the step of manual meter reading and avoiding damage to the water meter due to cold weather. However, the structure of the smart water meter is fixed, and the lengths of its inlet and outlet pipes are fixed, which cannot adapt to the connection requirements of water pipes with different spacing, and has certain limitations. Utility Model Content

[0005] The purpose of this utility model is to provide a smart water meter with a telescopic structure to solve the problem in the background art where the smart water meter has a fixed structure, and the lengths of its inlet and outlet pipes are fixed, which cannot adapt to the connection requirements of water pipes with different spacings and has certain limitations.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A smart water meter with a telescopic structure includes a water meter body; a fixed pipe is provided at the top of the water meter body, and a connecting pipe is provided at the bottom of the water meter body. A water inlet pipe is provided at the top of the water meter body, and the bottom of the water inlet pipe extends into the interior of the fixed pipe. An anti-slip sleeve is attached to the outer surface of the water inlet pipe. The inner wall of the fixed pipe is tightly fitted with the outer surface of the anti-slip sleeve. Several fixed plates are fixedly installed on the outer side of the fixed pipe. A screw is threaded into the interior of each fixed plate. A pressure plate is rotatably installed on the inner side of each screw through the interior of each fixed plate and through a bearing. A water outlet pipe is provided at the bottom of the water meter body. The top of the water outlet pipe extends into the interior of the connecting pipe. A rubber sleeve is attached to the outer surface of the water outlet pipe. The inner wall of the connecting pipe is tightly fitted with the outer surface of the rubber sleeve. Several connecting plates are fixedly installed on the outer side of the connecting pipe. A threaded rod is threaded into the interior of each connecting plate. A pressure strip is rotatably installed on the inner side of each threaded rod through the interior of each connecting plate and through a bearing.

[0008] The smart water meter structure proposed in the background technology is fixed, with fixed lengths for the inlet and outlet pipes, which cannot adapt to the connection requirements of water pipes with different spacings, thus having certain limitations. In this application, by inserting the inlet pipe into the fixed pipe, the opening of the fixed pipe can be extended. By inserting the outlet pipe into the connecting pipe, the opening of the connecting pipe can also be extended. Furthermore, by sliding the inlet pipe inside the fixed pipe and the outlet pipe inside the connecting pipe, the water meter body can be extended and retracted. After adjustment, by rotating the screw, the pressure plate is moved, allowing the pressure plate to compress and limit the anti-slip sleeve. By rotating the lead screw, the pressure strip is moved, allowing the pressure strip to compress and limit the rubber sleeve. This allows it to adapt to the connection requirements of water pipes with different spacings, facilitating subsequent installation of the water meter body and improving installation convenience.

[0009] A further improvement of this utility model is that the anti-slip sleeve is made of rubber material, and each pressure plate has a protrusion on its inner side, and each protrusion is pressed against the outer surface of the anti-slip sleeve.

[0010] By adopting the above technical solution, by installing a protrusion, the protrusion can be made to fit against the surface of the anti-slip sleeve during the movement of the pressure plate. Furthermore, by using rubber material for the anti-slip sleeve, the protrusion can squeeze the anti-slip sleeve, causing the anti-slip sleeve to deform to a certain extent, thereby increasing the contact area between the pressure plate and the anti-slip sleeve, thus improving the limiting effect on the water inlet pipe.

[0011] A further improvement of this utility model is that: the outer side of each screw extends into the interior of the fixing plate, and a handwheel is fixedly installed on the outer surface of each screw.

[0012] By adopting the above technical solution, the contact area between the operator's hand and the screw can be increased by installing a handwheel, so as to facilitate the rotation of the screw.

[0013] A further improvement of this utility model is that the rubber sleeve is made of rubber material, and each pressure strip has a locking block on its inner side, and each locking block is pressed against the outer surface of the rubber sleeve.

[0014] In the above technical solution, by installing a locking block, the locking block can be brought into contact with the surface of the rubber sleeve during the movement of the pressure strip. By using rubber material for the rubber sleeve, the locking block can squeeze the rubber sleeve, and the inner wall of the connecting pipe is tightly fitted with the outer surface of the rubber sleeve, causing the rubber sleeve to deform to a certain extent, thereby increasing the contact area between the pressure strip and the rubber sleeve, thus improving the limiting effect on the water outlet pipe.

[0015] A further improvement of this utility model is that: the outer side of each lead screw extends into the interior of the connecting plate, and a handle is fixedly installed on the outer surface of each lead screw.

[0016] The above technical solution increases the contact area between the operator's hand and the lead screw by installing a handle, thus facilitating the rotation of the lead screw.

[0017] A further improvement of this utility model is that: several sliders are fixedly installed around the water inlet pipe at the bottom of the anti-slip sleeve, and several grooves matching the shape of the sliders are opened on the inner wall of the water meter body, with each slider slidingly connected to each groove.

[0018] By adopting the above technical solution, the contact area between the water inlet pipe and the inner wall of the fixed pipe can be increased by installing sliders and grooves, thus preventing the water inlet pipe from rotating in the horizontal direction during movement and improving the stability of the water inlet pipe extension and contraction adjustment.

[0019] A further improvement of this utility model is that: several movable blocks are fixedly installed around the water outlet pipe at the top of the rubber sleeve, and several movable grooves matching the shape of the movable blocks are opened on the inner wall of the water meter body, with each movable block slidingly connected to each movable groove.

[0020] By adopting the above technical solution, the contact area between the water outlet pipe and the inner wall of the connecting pipe can be increased by installing the movable block and the movable groove, so as to prevent the water outlet pipe from rotating in the horizontal direction during movement, thereby improving the stability of the water outlet pipe extension and contraction adjustment.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a smart water meter with a telescopic structure. By inserting the inlet pipe and outlet pipe into the fixed pipe and connecting pipe respectively, the inlet and outlet can be extended respectively. Furthermore, by sliding the inlet pipe inside the fixed pipe and the outlet pipe inside the connecting pipe, the inlet and outlet of the water meter body can be telescopically adjusted. After adjustment, the inlet and outlet pipes are squeezed and limited, so that the water meter body can adapt to the connection requirements of water pipes with different spacings during installation, which facilitates the subsequent installation of the water meter body and improves the convenience of installation.

[0023] 2. This utility model provides a smart water meter with a telescopic structure. By rotating the screw, the protrusion can be driven to fit against the surface of the anti-slip sleeve, and the protrusion can squeeze the anti-slip sleeve, causing it to deform to a certain extent, thereby improving the limiting effect on the water inlet pipe. By rotating the lead screw, the locking block can be driven to fit against the surface of the rubber sleeve, and the locking block can squeeze the rubber sleeve, causing it to deform to a certain extent, thereby improving the limiting effect on the water outlet pipe.

[0024] 3. This utility model provides an intelligent water meter with a telescopic structure. By sliding the slider inside the groove, the contact area between the inlet pipe and the inner wall of the fixed pipe can be increased, preventing the inlet pipe from rotating horizontally during movement. By sliding the movable block inside the movable groove, the contact area between the outlet pipe and the inner wall of the connecting pipe can be increased, preventing the outlet pipe from rotating horizontally during movement, thereby improving the stability of the outlet pipe telescopic adjustment.

[0034] The present invention will be further described in detail below with reference to embodiments:

[0035] Example 1

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a smart water meter with a telescopic structure, including a water meter body 1; a fixing pipe 2 is provided at the top of the water meter body 1, a connecting pipe 3 is provided at the bottom of the water meter body 1, a water inlet pipe 4 is provided at the top of the water meter body 1, the bottom of the water inlet pipe 4 extends into the interior of the fixing pipe 2, an anti-slip sleeve 12 is attached to the outer surface of the water inlet pipe 4, the inner wall of the fixing pipe 2 is tightly fitted with the outer surface of the anti-slip sleeve 12, and several fixing plates 6 are fixedly installed on the outer side of the fixing pipe 2, each fixing plate 6 is threadedly connected to a screw 14, and each screw 14... A pressure plate 7 is installed through the interior of each fixed plate 6 and rotates through the bearing on the inner side of 4. A water outlet pipe 5 is provided at the bottom of the water meter body 1. The top of the water outlet pipe 5 extends into the interior of the connecting pipe 3. A rubber sleeve 15 is attached to the outer surface of the water outlet pipe 5. The inner wall of the connecting pipe 3 is tightly fitted with the outer surface of the rubber sleeve 15. Several connecting plates 9 are fixedly installed on the outer side of the connecting pipe 3. A screw rod 17 is threaded into the interior of each connecting plate 9. A pressure strip 10 is installed through the interior of each connecting plate 9 and rotates through the bearing on the inner side of each screw rod 17.

[0037] In this embodiment, the smart water meter structure proposed in the background art is fixed, and the lengths of its inlet pipe 4 and outlet pipe 5 are fixed, which cannot adapt to the connection requirements of water pipes with different spacings and has certain limitations. In this application, by inserting the inlet pipe 4 into the fixed pipe 2, the opening of the fixed pipe 2 can be extended. By inserting the outlet pipe 5 into the connecting pipe 3, the opening of the connecting pipe 3 can be extended. Furthermore, by sliding the inlet pipe 4 inside the fixed pipe 2 and the outlet pipe 5 inside the connecting pipe 3, the water meter body 1 can be extended and retracted. After adjustment, by rotating the screw 14, the pressure plate 7 is moved, so that the pressure plate 7 can squeeze and limit the anti-slip sleeve 12. By rotating the lead screw 17, the pressure strip 10 is moved, so that the pressure strip 10 can squeeze and limit the rubber sleeve 15. Thus, it can adapt to the connection requirements of water pipes with different spacings, so as to facilitate the subsequent installation of the water meter body 1 and improve the convenience of installation.

[0038] Example 2

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, based on Embodiment 1, this utility model provides the following technical solution: Preferably, the anti-slip sleeve 12 is made of rubber material, each pressure plate 7 has a protrusion 18 on its inner side, each protrusion 18 is pressed against the outer surface of the anti-slip sleeve 12, each screw 14 extends out of the interior of the fixing plate 6, and each screw 14 has a handwheel 8 fixedly installed on its outer surface, the rubber sleeve 15 is made of rubber material, each pressure strip 10 has a locking block 19 on its inner side, each locking block 19 is pressed against the outer surface of the rubber sleeve 15, each lead screw 17 extends out of the interior of the connecting plate 9, and each lead screw 17 has a handle 11 fixedly installed on its outer surface.

[0040] In this embodiment, by installing the protrusion 18, the protrusion 18 can be brought into contact with the surface of the anti-slip sleeve 12 during the movement of the pressure plate 7. Furthermore, by using rubber for the anti-slip sleeve 12, the protrusion 18 can compress the anti-slip sleeve 12, causing it to deform to a certain extent, thereby increasing the contact area between the pressure plate 7 and the anti-slip sleeve 12, thus improving the limiting effect on the water inlet pipe 4. Installing the handwheel 8 expands the contact area between the operator's hand and the screw 14, facilitating the rotation of the screw 14. Installing the locking block 19... During the movement of the pressure strip 10, the locking block 19 can be brought into contact with the surface of the rubber sleeve 15. By using rubber material for the rubber sleeve 15, the locking block 19 can squeeze the rubber sleeve 15, and the inner wall of the connecting pipe 3 is tightly fitted with the outer surface of the rubber sleeve 15, causing the rubber sleeve 15 to deform to a certain extent, thereby increasing the contact area between the pressure strip 10 and the rubber sleeve 15, thus improving the limiting effect on the water outlet pipe 5. By installing the handle 11, the contact area between the operator's hand and the screw 17 can be expanded, so as to facilitate the rotation operation of the screw 17.

[0041] Example 3

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, based on Embodiment 2, the present invention provides the following technical solution: Preferably, a plurality of sliders 13 are fixedly installed around the water inlet pipe 4 at the bottom of the anti-slip sleeve 12, and a plurality of grooves matching the shape of the sliders 13 are opened on the inner wall of the water meter body 1. Each slider 13 is slidably connected to each groove. A plurality of movable blocks 16 are fixedly installed around the water outlet pipe 5 at the top of the rubber sleeve 15, and a plurality of movable grooves matching the shape of the movable blocks 16 are opened on the inner wall of the water meter body 1. Each movable block 16 is slidably connected to each groove.

[0043] In this embodiment, by installing the slider 13 and the groove, the contact area between the water inlet pipe 4 and the inner wall of the fixed pipe 2 can be increased, preventing the water inlet pipe 4 from rotating in the horizontal direction during movement, thereby improving the stability of the extension and retraction adjustment of the water inlet pipe 4; by installing the movable block 16 and the movable groove, the contact area between the water outlet pipe 5 and the inner wall of the connecting pipe 3 can be increased, preventing the water outlet pipe 5 from rotating in the horizontal direction during movement, thereby improving the stability of the extension and retraction adjustment of the water outlet pipe 5.

[0044] The working principle of this smart water meter with a telescopic structure is explained in detail below.

[0045] like Figures 1-7As shown, when the water meter body 1 needs to be installed, the operator can insert the slider 13 into the sliding groove, and then insert the inlet pipe 4 into the inside of the fixed pipe 2 to extend the inlet of the fixed pipe 2. Then, the movable block 16 is inserted into the movable groove, and then the outlet pipe 5 is inserted into the inside of the connecting pipe 3 to extend the opening of the connecting pipe 3. Furthermore, depending on the actual installation requirements, the operator can move the inlet pipe 4 and the outlet pipe 5 to adjust the position of the inlet of the fixed pipe 2 and the outlet of the connecting pipe 3. After adjustment, the operator can turn the handwheel 8, which in turn drives the screw 14 to rotate, thereby driving the pressure plate 7 to approach the anti-slip sleeve 12, so that the protrusion 18 and the anti-slip sleeve 12 press against each other. Then, turn the handle 11, which in turn drives the lead screw 17 to rotate, thereby driving the pressure strip 10 to approach the rubber sleeve 15. The inner wall of the connecting pipe 3 is tightly fitted with the outer surface of the rubber sleeve 15, so that the locking block 19 and the rubber sleeve 15 press against each other, thereby limiting and fixing the inlet pipe 4 and the outlet pipe 5, so that the water meter body 1 can adapt to the water pipe connection requirements of different spacing.

[0046] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
