Description

Technical Field

[0001] The utility model relates to the technical field of heat energy meters, in particular to a heat energy meter with a positioning and installation function. Background Art

[0002] A heat meter is an instrument used to measure the heat absorbed or released in a heat exchange circuit. Its working principle is to calculate the heat consumption by measuring the flow rate of hot water flowing through the heat exchange system and the temperature difference between the supply and return water. The heat meter mainly consists of three parts: a flow sensor, a temperature sensor and a calculator. The flow sensor is used to measure the flow rate of hot water, the temperature sensor measures the temperature of the supply and return water respectively, and the calculator calculates the consumed heat based on the flow rate and temperature difference data. The heat meter has a wide range of applications and is often used in centralized heating systems to measure the heat use of users for reasonable charging and energy management. It helps to improve energy utilization efficiency and promote energy conservation and emission reduction.

[0003] According to a heat meter with a throttling function disclosed (publication number: CN208503491U), in the above application, when the flange and the heating pipe are actually installed, there will be other water pipes in the pipe well of the heating pipe, such as: water supply pipes, wire pipes, etc. If the pipes are sealed or complicated, it will be inconvenient to align the flange holes on the heat meter and the heating pipe, resulting in an offset in the installation, which will make the connection between the heat meter and the heating pipe loose, which will not only affect the heating but also easily cause damage to the heating pipe or the heat meter. The flange may be deformed due to the long-term heating of the heating pipe, and the flange in the above application cannot adapt to the flanges of heating pipes of different sizes, which may cause the heat meter to be unable to be tightly installed.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a heat meter with a positioning and installation function, comprising a heat meter body 1, a heating pipe 4 and a mounting pipe 3, the heat meter body 1 passes through the mounting pipe 3 and is fixedly connected, and a positioning portion 2 is provided on the surface of the mounting pipe 3, and the positioning portion 2 comprises: a telescopic tube 21, a spring 1 22, a rotating disk 23, an arc groove 24, a fixed disk 25, a movable groove 26, a sliding groove 27, a flange 28, a mounting groove 29, a T-shaped hinge block 210, a linkage rod 211, a connecting block 212, a torsion spring 213, a mounting sheet 214, a vertical rod 215, a horizontal rod 216, a contraction groove 217, a nut 218, a spring 219, a resistance block 220, and a mounting hole 221.

[0024] The telescopic tube 21 penetrates the mounting tube 3, and the telescopic tube 21 is slidably connected to the mounting tube 3. A spring 22 is fixedly connected to the right side of the telescopic tube 21. The end of the spring 22 away from the telescopic tube 21 is fixedly connected to the inner side of the mounting tube 3. The telescopic tube 21 penetrates and rotatably connects to a turntable 23. An arc groove 24 is provided on the surface of the turntable 23. The inner side of the fixed disk 25 is penetrated by the telescopic tube 21, and the fixed disk 25 is slidably connected to the telescopic tube 21. A movable groove 26 is provided on the surface of the fixed disk 25. The mounting piece 214 is connected to the T-shaped hinge through the connecting block 212. The hinged position of the connecting block 210 rotates to a certain extent, thereby forcing the mounting piece 214 to be embedded in the movable groove 26. A sliding groove 27 is provided on the inner side of the movable groove 26. A flange 28 is fixedly connected to the side of the telescopic tube 21 away from the heat meter body 1. When the heat meter body 1 is installed, the flange 28 fixedly connected to the surface of the telescopic tube 21 is aligned with the flange of the heating pipe 4, and the mounting tube 3 is pushed. The telescopic tube 21 is driven by a spring 22 to make the flange 28 fit with the flange of the heating pipe 4. A mounting groove 29 is provided on the surface of the flange 28. A T-shaped hinge block 210 penetrates and is slidably connected to the inner side of the slide groove 27. A linkage rod 211 is fixedly connected to the surface of the T-shaped hinge block 210 on one side close to the turntable 23. The turntable 23 is rotated to make the arc groove 24 opened on the surface of the turntable 23 contact the linkage rod 211. However, since the linkage rod 211 is fixedly connected to the T-shaped hinge block 210 and the T-shaped hinge block 210 is slidably connected in the slide groove 27, the linkage rod 211 slides along the slide groove 27 when it is contacted by the arc groove 24. The T-shaped hinge block 210 will drive the cross bar 216 to move toward the center of the flange of the heating pipe 4 through the mounting plate 214 and the vertical rod 215, and the linkage rod 211 penetrates the arc groove 24. A connecting block 212 penetrates and is hingedly connected to the inner side of the T-shaped hinge block 210, and a mounting plate 214 is fixedly connected to the surface of the connecting block 212. Continuing to push the mounting tube 3 will shorten the distance between the mounting tube 3 and the telescopic tube 21, and the telescopic tube 21 will be relatively retracted into the mounting tube 3, and the spring 22 will be compressed. During the contraction of the telescopic tube 21, the mounting plate 214 will be pressed, and the mounting plate 214 will rotate to a certain extent at the position where the connecting block 212 is hinged to the T-shaped hinge block 210. A vertical rod 215 is fixedly connected to the surface of the mounting plate 214 on one side away from the connecting block 212. A torsion spring 213 is fixedly connected between the connecting block 212 and the T-shaped hinge block 210. The mounting plate 214 can slide back and forth in the movable groove 26 following the T-shaped hinge block 210, so that the vertical rod 215 and the horizontal rod 216 can also move together with the mounting plate 214. The mounting plate 214 and the mounting groove 29 both have a certain length, so that the positioning part 2 can adapt to the flanges of heating pipes 4 of different sizes for connection.One end of the vertical rod 215 away from the mounting plate 214 is fixedly connected to the cross rod 216, and a contraction groove 217 is provided on the inner side of the cross rod 216. When the mounting plate 214 rotates, the vertical rod 215 and the cross rod 216 are driven to rotate together. When the cross rod 216 rotates, the inclined surface at the bottom of the abutment block 220 abuts against the flange edge of the heating pipe 4, thereby forcing the abutment block 220 to push the nut 218 to contract into the contraction groove 217. The inner side of the contraction groove 217 is penetrated and slidably connected with the nut 218. The second spring 219 is fixedly connected to the surface of the nut 218 near the contraction groove 217. When the nut 218 contracts, the second spring 219 will be compressed. If the abutment block 220 is not aligned with the flange hole of the heating pipe 4 at this time, the fixing plate 25 can be rotated first, and the second spring 219 always pushes the nut 218 so that the abutment block 220 abuts against the flange surface of the heating pipe 4. The end of the second spring 219 away from the nut 218 is fixedly connected to the inner side of the contraction groove 217. A mounting hole 221 is provided on the inner side of the contraction groove 217, and the abutment block 220 is fixedly connected to the side of the nut 218 away from the second spring 219.

[0025] Based on the above embodiment, when the heat meter body 1 is installed, the flange 28 fixedly connected to the surface of the telescopic tube 21 is aligned with the flange of the heating pipe 4, and the mounting tube 3 is pushed. The spring 1 22 drives the telescopic tube 21 to make the flange 28 fit with the flange of the heating pipe 4. The mounting tube 3 is pushed further, which shortens the distance between the mounting tube 3 and the telescopic tube 21, and relatively shrinks the telescopic tube 21 into the mounting tube 3, compresses the spring 1 22, and presses the mounting piece 214 during the shrinkage of the telescopic tube 21, and the mounting piece 214 is hinged to the T-shaped hinge block 210 through the connecting block 212. The mounting plate 214 is rotated to a certain extent, thereby forcing the mounting plate 214 to be embedded in the movable groove 26. When the mounting plate 214 rotates, the vertical rod 215 and the horizontal rod 216 are driven to rotate together. When the horizontal rod 216 rotates, the inclined surface at the bottom of the abutment block 220 abuts against the flange edge of the heating pipe 4, thereby forcing the abutment block 220 to push the nut 218 to retract into the retraction groove 217. When the nut 218 retracts, the spring 219 is compressed. If the abutment block 220 is not aligned with the flange hole of the heating pipe 4 at this time, the fixing plate 25 can be rotated first, and the spring 219 always pushes the nut 218 to make the abutment block 220 abut against the heating pipe 4. If the abutment block 220 is still not aligned with the flange hole of the heating pipe 4 after one rotation, the turntable 23 can be rotated to make the arc groove 24 on the surface of the turntable 23 abut the linkage rod 211. However, since the linkage rod 211 is fixedly connected to the T-shaped hinge block 210, and the T-shaped hinge block 210 is slidably connected in the slide groove 27, the linkage rod 211 slides along the slide groove 27 when it is abutted by the arc groove 24, and the T-shaped hinge block 210 drives the cross bar 216 to move toward the center of the flange of the heating pipe 4 through the mounting piece 214 and the vertical rod 215, so as to adjust the distance between the abutment block 220 and the flange of the heating pipe 4 The fixing plate 25 is rotated until the abutment block 220 is aligned with the flange hole of the heating pipe 4, and the compressed spring 219 pushes the nut 218 to insert the abutment block 220 into the flange hole of the heating pipe 4, and then the bolt is screwed into the mounting hole 221 to connect with the nut 218, and the bolt is screwed into the mounting groove 29 and the mounting plate 214 to install the telescopic tube 21 and the mounting pipe 3 and the flange of the heating pipe 4. By pushing and rotating the mounting pipe 3, the heat meter body 1 can accurately position and connect the flange of the mounting pipe 3 and the heating pipe 4 in some spaces where pipes are densely packed.

[0026] In addition, the mounting plate 214 can slide back and forth in the movable groove 26 following the T-shaped hinge block 210, so that the vertical rod 215 and the horizontal rod 216 can also move together with the mounting plate 214, and the mounting plate 214 and the mounting groove 29 both have a certain length, so that the positioning part 2 can adapt to the flanges of heating pipes 4 of different sizes for connection, and has a wider range of applications.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
