Description

Technical Field

[0001] The present invention relates to the technical field of heat metering, and specifically relates to a heat metering device. Background Art

[0002] A heat meter is an instrument for calculating heat. The working principle of the heat meter: A pair of temperature and heat sensors are respectively installed on the upflow pipe and the downflow pipe through which the heat-carrying fluid passes. The flow meter is installed on the fluid inlet or the return pipe (the position of the flow meter installation is different, and the final measurement result is also different). The flow meter emits a pulse signal proportional to the flow rate. A pair of temperature and heat sensors give analog signals indicating the temperature level. The calculator collects the signals from the flow meter and the temperature and heat sensors, and calculates the heat obtained by the heat exchange system using the calculation formula.

[0003] However, currently, when installing a heat meter, it is generally installed in a position similar to a water meter box on the residential floor. The heating water inlet pipe of each household passes through a heat meter. The return pipe of each household is connected to one of the heat sensors on the heat meter, and the other heat sensor is connected to the inlet pipe to measure the heat for charging. The heat meter of each household is connected to the heat sensor on the corresponding return pipe through a long wire. Since there are many heat meters installed inside the meter box and the wires between each heat meter and the return pipe are long and messy, and there is no component on the heat meter for storing and fixing the connecting wires of the heat sensors of each household, it is not easy to sort out the wires when repairing the heat meter, which increases the difficulty of repairing or measuring the heat meter. The display screen of each heat meter is rotationally connected to the meter body, and the angle between the display screen and the meter body is difficult to adjust. The space inside the meter box is small and the number of heat meters is large, which is not convenient for observing the display screen for meter reading. There is no fixing component between the inlet pipe and the return pipe of the heat meter. When installing or repairing one of the pipes, the other pipe will be shaken. The two pipes are not connected as a whole, and it is easy to cause loosening and water leakage between the two pipes and the meter body during maintenance. Summary of the Invention

A top plate and a mounting plate are relatively fixedly connected to the side surface of the support plate. A mounting plate is slidably connected to the mounting plate. A pressing plate is slidably connected to the mounting plate. A first spring is clamped between the pressing plate and the top plate.

[0006] Specifically, the measuring mechanism further includes a first wire and a second wire. The display is electrically connected to the first wire and the second wire. Heat sensors are installed at the ends of the first wire and the second wire. One of the heat sensors is threadedly connected to the heat meter body.

[0007] Specifically, the limiting mechanism further includes fixed teeth and limiting teeth. Fixed teeth with an arc-shaped bottom are equidistantly fixedly connected to the bottom of the display. A limiting tooth is fixedly connected to the top of the support plate. The limiting tooth is buckled between two adjacent fixed teeth.

[0008] Specifically, the limiting mechanism further includes two sliding grooves. Two sliding grooves are opened on the fixing plate. Sliding blocks are slidably connected to both of the two sliding grooves. The tops of the two sliding blocks are respectively fixedly connected to the bottom of the support plate. L-shaped fixing frames are horizontally slidably connected between the support plate and one of the sliding blocks. Two second springs are clamped between the fixing frame and the support plate. A plurality of buckling holes are equidistantly provided on the inner wall of the fixing plate. One end of the fixing frame is buckled with the buckling hole.

[0009] Specifically, the wire winding mechanism further includes a buckling plate. A buckling plate with a wavy structure is fixedly connected to one side of the pressing plate. The top of the buckling plate is arc-shaped, and the two sides of the buckling plate are parallel.

[0010] Specifically, the conveying mechanism includes two fixed pipes. Two fixed pipes are relatively connected to both ends of the heat meter body. Conveying pipes are provided at the opposite ends of the two fixed pipes. Nuts are sleeved on both of the two conveying pipes. The two nuts are threadedly connected to the two conveying pipes respectively.

[0011] Specifically, the support mechanism includes two fixed disks. Fixed disks are fixedly connected to the opposite sides of the two nuts. Rotating disks are rotatably connected to the opposite sides of the two fixed disks. Fixed columns are fixedly connected to the bottoms of the two rotating disks. Sleeve members are slidably connected to the outer sides of the two fixed columns.

[0012] Specifically, the support mechanism further includes a bottom plate. Bottom plates with an arc-shaped structure are fixedly connected to the bottoms of the two sleeve members.

[0013] Specifically, the reinforcement mechanism includes two sleeve plates. Sleeve plates are slidably connected to the two fixed columns. Arc-shaped card slots are equidistantly formed on the opposite sides of the two fixed columns. The two sleeve plates are engaged with two groups of card slots, and the ends of the sleeve plates are in a U-shaped structure.

[0014] Specifically, the reinforcement mechanism further includes two screw rods. Two screw rods are threadedly connected to the opposite ends of the two sleeve plates. The threads of the two screw rods are arranged in opposite directions. A driving column with a hexagonal prism structure is fixedly connected between the two screw rods.

[0015] The beneficial effects of the present invention are as follows: (1) For a heat supply metering device according to the present invention, a wire winding mechanism is provided at the bottom of the display. When installing the entire device, the heat sensor on the wire two needs to be inserted into the return water pipe. The length of the wire two between the display and the return water pipe is relatively long, which is likely to cause messy wiring in the meter box. During installation, the wire two can be folded and wound together. Further, hold the support plate and pull the buckle on the pressing plate. At this time, the first spring contracts, and a large gap is generated between the pressing plate and the mounting plate. The wound wire two can be inserted between the pressing plate and the mounting plate. After releasing the buckle, the first spring resets, realizing the winding of the wire two, avoiding the entanglement of the wire harnesses of multiple meters in the meter box, and facilitating installation and maintenance.

[0016] (2) For a heat supply metering device according to the present invention, a limiting mechanism is provided on the support plate and the measuring mechanism. After the wire two is received into the interior of the wire winding mechanism, the support plate can be held, and the display is rotated away from the meter housing. At this time, an included angle is generated between the meter housing and the display. The slider at the bottom of the support plate is slid along the sliding groove on the fixing plate. After releasing the display, the torsion of the torsion spring presses the support plate, and the support plate can be continuously slid as needed. When sliding, the limiting teeth can automatically move and engage on the fixed teeth, realizing the fixation of the support plate, enabling the wire two to be held at the bottom of the corresponding display, avoiding the loosening and dropping of the support plate, and the fixing frame and the buckling hole further reinforce the support plate. And by pressing the fixing frame and separating the buckling hole from it, the disassembly of the support plate is realized. When the support plate is fixed, the display is also limited. By adjusting the angle of the display in this way, it is convenient to read the meter inside the meter box.

[0017] (3) For a heat metering device according to the present invention, a turntable is rotatably connected to the fixing plates on both nuts. A fixing column is fixedly connected to the bottom of the turntable, and a reinforcement mechanism is installed between the two fixing columns. The extended lengths of the two sliding shells can be adjusted according to the distance between the delivery pipe and the return pipe, and then the sliding shells are limited by the reinforcement mechanism, so that the delivery pipe and the return pipe form a whole, avoiding water leakage caused by the shaking of the delivery pipe or the delivery pipe during maintenance. Moreover, the reinforcement mechanism between the two fixing columns can vertically fix the two fixing columns at the same time to complete the limitation of the sliding shells, further strengthening the fastening between the two nuts and avoiding loosening and water leakage between the delivery pipe and the fixed pipe.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0022] Such as Figures 1 - 11As shown in the figure, a heat metering device according to the present invention includes a heat meter body 1 and conveying mechanisms 3 installed at both ends of the heat meter body 1. Support mechanisms 4 are installed on both of the conveying mechanisms 3, and a reinforcement mechanism 5 is provided between the two support mechanisms 4. A measuring mechanism 2 is installed on the heat meter body 1, a limiting mechanism 7 is installed on the measuring mechanism 2, and a wire winding mechanism 6 is clamped between the limiting mechanism 7 and the measuring mechanism 2; the measuring mechanism 2 includes a meter housing 201. The heat meter body 1 is provided with the meter housing 201. Two lower connecting plates 207 are fixedly connected to the meter housing 201 relatively. Rotating shafts 209 are fixedly connected to both of the two lower connecting plates 207. Upper connecting plates 206 are rotatably connected to both of the two rotating shafts 209. A display 202 is fixedly connected to the two upper connecting plates 206. A torsion spring 208 is clamped between the rotating shaft 209 and the upper connecting plate 206. The wire winding mechanism 6 includes a support plate 601. The support plate 601 is clamped between the display 202 and a fixing plate 702. A top plate 602 and a mounting plate 605 are fixedly connected to the side of the support plate 601 relatively. A pressing plate 604 is slidably connected to the mounting plate 605. A first spring 603 is clamped between the pressing plate 604 and the top plate 602; the wire winding mechanism 6 further includes a clamping plate 606. A clamping plate 606 with a wavy structure is fixedly connected to one side of the pressing plate 604. The top of the clamping plate 606 is in an arc structure, and the two sides of the clamping plate 606 are arranged in parallel; after installing the heat meter body 1 of one household, since there is a certain distance between the water inlet pipe and the water return pipe, the length of the second wire 205 is relatively long. At this time, a support plate 601 can be taken, the second wire 205 is folded and stored together to change the length of the second wire 205. Further, hold the support plate 601 and pull the clamping plate 606 in the direction of the top plate 602 to make the distance between the pressing plate 604 and the mounting plate 605 larger, and the first spring 603 contracts. Place the folded second wire 205 between the pressing plate 604 and the mounting plate 605. After releasing the clamping plate 606, the first spring 603 resets. Further, the pressing plate 604 presses the stored second wire 205, and the second wire 205 is clamped between the pressing plate 604 and the mounting plate 605, avoiding the entanglement of the second wires 205 of multiple households and affecting the maintenance. Moreover, the top of the pressing plate 604 is in an arc structure, which is convenient for pressing and clamping the second wires 205 with different volumes stored.

[0023] Specifically, as shown in the figure, the limiting mechanism 7 includes a fixing plate 702, and the fixing plate 702 is fixedly connected to the watch case 201. The limiting mechanism 7 further includes a fixed tooth 701 and a limiting tooth 706. The bottom of the display 202 is fixedly connected with fixed teeth 701 with an arc-shaped bottom at equal intervals. The top of the support plate 601 is fixedly connected with a limiting tooth 706, and the limiting tooth 706 is buckled between two adjacent fixed teeth 701. The limiting mechanism 7 further includes two sliding grooves 703. Two sliding grooves 703 are formed on the fixing plate 702. Two sliders 705 are slidably connected to the two sliding grooves 703 respectively. The tops of the two sliders 705 are fixedly connected to the bottom of the support plate 601 respectively. An L-shaped fixing frame 704 is horizontally slidably connected between the support plate 601 and one of the sliders 705. Two second springs 707 are clamped between the fixing frame 704 and the support plate 601. A plurality of fastening holes 708 are equidistantly arranged on the inner wall of the fixing plate 702. One end of the fixing frame 704 is buckled with the fastening hole 708. After the redundant wire two 205 is received on the mounting plate 605, the display 202 on the watch case 201 can be pulled. At this time, the upper connecting plate 206 can rotate around the rotating shaft 209 on the lower connecting plate 207, and the torsion spring 208 is opened. An included angle will also be generated between the display 202 and the fixing plate 702. The support plate 601 can be moved along the two sliding grooves 703 to the bottom of the display 202 through the slider 705 at its bottom. The display 202 can be released. At this time, the display 202 presses on the top of the support plate 601. The fixing frame 704 on the side wall of the support plate 601 can be held as needed, and the second spring 707 contracts. Then the fixing frame 704 will not be blocked by the fastening hole 708. When the display 202 is pushed to the specified angle, the fixing frame 704 is released. At this time, the second spring 707 is reset, and the fixing frame 704 is inserted into the specified fastening hole 708 to complete the fixation of the support plate 601 and prevent it from loosening. Moreover, when the support plate 601 is moved, the fixed tooth 701 at its top can jump on the limiting tooth 706 at the bottom of the display 202. When the support plate 601 stops moving, the limiting tooth 706 will be clamped between two fixed teeth 701 to further limit the support plate 601 and increase the stability, ensuring that the wire two 205 of each household corresponds to the heat meter body 1. That is, while fixing the support plate 601, the tilt angle of the display 202 is adjusted, which is beneficial to observing the values inside the meter box for meter reading.

[0024] Specifically, as shown in the figure, the measuring mechanism 2 further includes a first wire 203 and a second wire 205. The display 202 is electrically connected to the first wire 203 and the second wire 205. Heat sensors 204 are installed at the ends of the first wire 203 and the second wire 205. One of the heat sensors 204 is threadedly connected to the heat meter body 1; the conveying mechanism 3 includes two fixed pipes 301. Two fixed pipes 301 are oppositely connected to both ends of the heat meter body 1. Conveying pipes 303 are provided at the opposite ends of the two fixed pipes 301. Nuts 302 are sleeved on the two conveying pipes 303. The two nuts 302 are threadedly connected to the two conveying pipes 303 respectively; when installing the entire device, take the entire device into the meter box on the residential floor, make the two fixed pipes 301 abut against the ends of the two conveying pipes 303 respectively, and further rotate the nuts 302 on the two conveying pipes 303 to achieve threaded connection between the two nuts 302 and the two fixed pipes 301 respectively, completing the connection between the fixed pipes 301 and the two conveying pipes 303. Hot water enters from one conveying pipe 303, passes through the heat meter body 1 and is discharged from the other conveying pipe 303. And when rotating the nut 302, since the turntable 402 is rotatably connected to the fixed disk 401, the rotation of the nut 302 will not be affected. After the pipe body is installed, threadedly connect the heat sensor 204 at the end of the first wire 203 on the display 202 to the heat meter body 1, and threadedly connect the heat sensor 204 on the second wire 205 to the return water pipe. And the return water pipe can be arranged parallel to the conveying pipe 303, which is beneficial for the bottom plate 405 to support the conveying pipe 303 and the return water pipe mutually. During measurement, the heat sensor 204 on the first wire 203 can measure the temperature when the hot water enters, and the heat sensor 204 on the second wire 205 can measure the temperature of the hot water at the discharge return water pipe. The heat meter body 1 can measure the used heat according to the temperature difference, and the value can be observed from the display 202.

[0025] Specifically, as shown in the figure, the support mechanism 4 includes two fixed disks 401. Fixed disks 401 are fixedly connected to the opposite sides of the two nuts 302. Rotating disks 402 are rotatably connected to the opposite sides of the two fixed disks 401. Fixed columns 403 are fixedly connected to the bottoms of the two rotating disks 402. Sleeve 404 is slidably connected to the outside of the two fixed columns 403. The support mechanism 4 further includes a bottom plate 405. Bottom plates 405 with an arc-shaped structure are fixedly connected to the bottoms of the two sleeves 404. The reinforcement mechanism 5 includes two sleeve plates 501. Sleeve plates 501 are slidably connected to the two fixed columns 403. Arc-shaped card slots 504 are equidistantly arranged on the opposite sides of the two fixed columns 403. The two sleeve plates 501 are engaged with the two groups of card slots 504, and the ends of the sleeve plates 501 are in a U-shaped structure. The reinforcement mechanism 5 further includes two screw rods 502. Two screw rods 502 are threadedly connected to the opposite ends of the two sleeve plates 501. The threads of the two screw rods 502 are arranged in opposite directions. A driving column 503 with a hexagonal prism structure is fixedly connected between the two screw rods 502. After the entire device is installed, the return water pipe is installed at the bottoms of the two conveying pipes 303. Since the return water pipe and the conveying pipes 303 are arranged in parallel, the two bottom plates 405 can contact the return water pipe. The two rotating disks 402 can be rotated to move the two sleeves 404 to a position opposite to the return water pipe. The two sleeves 404 can be pulled according to the distance between the conveying pipe 303 and the return water pipe to make the bottom plate 405 contact the return water pipe. The two sleeve plates 501 are moved to the tops of the two sleeves 404. At this time, the sleeve plates 501 will correspond to the card slots 504 on the side walls of the fixed columns 403. Then, the driving column 503 between the two sleeve plates 501 is rotated. Since the threads on the two screw rods 502 are arranged in opposite directions, when the driving column 503 is rotated, the two screw rods 502 drive the two sleeve plates 501 to move relatively. Then, the two sleeve plates 501 will be engaged into the card slots 504 on the side walls of the two fixed columns 403, realizing the vertical limit of the sleeve 404. At this time, the return water pipe, the conveying pipe 303, the sleeve 404 and the fixed column 403 form an I-shaped structure, increasing the stability between the conveying pipe 303 and the return water pipe, avoiding shaking when one of them is repaired, affecting the other one and causing loosening and water leakage. And rotating the driving column 503 realizes the simultaneous movement of the two sleeve plates 501, realizing the horizontal fixation of the two fixed columns 403. At this time, the two nuts 302 will also be relatively squeezed, increasing the sealing performance between the fixed pipe 301 and the conveying pipe 303, avoiding water leakage.

[0026] When the present invention is in use, first, when installing the entire device, the entire device is taken inside the meter box on the residential floor. The two fixing pipes 301 are respectively abutted against the ends of the two conveying pipes 303. Further, the nuts 302 on the two conveying pipes 303 are rotated to achieve the threaded connection between the two nuts 302 and the two fixing pipes 301 respectively, completing the connection between the fixing pipe 301 and the two conveying pipes 303. Hot water enters from one conveying pipe 303, passes through the heat meter body 1, and then is discharged from the other conveying pipe 303. When rotating the nut 302, since the rotating disc 402 is rotatably connected to the fixed disc 401, the rotation of the nut 302 will not be affected. After the pipe body is installed, the heat sensor 204 at the end of the wire one 203 on the display 202 is threadedly connected to the heat meter body 1, and the heat sensor 204 on the wire two 205 is threadedly connected to the return water pipe. The return water pipe can be arranged parallel to the conveying pipe 303, which is beneficial for the bottom plate 405 to support the conveying pipe 303 and the return water pipe mutually. During measurement, the heat sensor 204 on the wire one 203 can measure the temperature when the hot water enters, and the heat sensor 204 on the wire two 205 can measure the temperature of the hot water at the discharged return water pipe. The heat meter body 1 can measure the used heat according to the temperature difference, and the value can be observed from the display 202; Then, after installing the heat meter body 1 of one household, since there is a certain distance between the water inlet pipe and the return water pipe, the length of the wire two 205 is relatively long. At this time, a support plate 601 can be taken, and the wire two 205 is folded and stored together to change the length of the wire two 205. Further, hold the support plate 601 and pull the buckle 606 in the direction of the top plate 602 to make the distance between the pressing plate 604 and the mounting plate 605 larger, and the first spring 603 contracts. Place the folded wire two 205 between the pressing plate 604 and the mounting plate 605. After releasing the buckle 606, the first spring 603 resets. Further, the pressing plate 604 presses the stored wire two 205, and the wire two 205 is clamped between the pressing plate 604 and the mounting plate 605, preventing the wire two 205 of multiple households from being wound together and affecting the maintenance. Moreover, the top of the pressing plate 604 is in an arc structure, which is convenient for pressing and clamping the wire two 205 with different volumes during storage; Next, after the redundant wire two 205 is received on the mounting plate 605, the display 202 on the watch case 201 can be toggled. At this time, the upper connecting plate 206 can rotate around the rotating shaft 209 on the lower connecting plate 207, and the torsion spring 208 expands. An included angle will also be generated between the display 202 and the fixing plate 702. The support plate 601 can be moved along the two sliding grooves 703 towards the bottom of the display 202 through the slider 705 at its bottom. The display 202 can be released. At this time, the display 202 presses on the top of the support plate 601. The fixing frame 704 on the side wall of the support plate 601 can be held as needed, and the spring two 707 contracts. Then, the fixing frame 704 will not be blocked by the buckle hole 708. When the display 202 is pushed to the specified angle, the fixing frame 704 is released. At this time, the spring two 707 resets, and the fixing frame 704 is inserted into the interior of the specified buckle hole 708 to complete the fixation of the support plate 601 and prevent it from loosening. Moreover, when the support plate 601 is moved, the fixing teeth 701 on its top can jump on the limit teeth 706 at the bottom of the display 202. When the support plate 601 stops moving, the limit teeth 706 will be engaged between the two fixing teeth 701 to further limit the support plate 601 and increase stability, ensuring that the wire two 205 of each household corresponds to the heat meter body 1. That is, while fixing the support plate 601, the tilt angle of the display 202 is adjusted, which is beneficial for observing the values inside the meter box for meter reading; Finally, after the installation of the entire device is completed, install the return pipe at the bottom of the two delivery pipes 303. Since the return pipe and the delivery pipes 303 are arranged in parallel, the two bottom plates 405 can abut against the return pipe. Rotate the two turntables 402 to move the two sliding sleeves 404 to a position opposite to the return pipe. Pull the two sliding sleeves 404 according to the distance between the delivery pipe 303 and the return pipe to make the bottom plate 405 abut against the return pipe. Move the two sleeve plates 501 to the tops of the two sliding sleeves 404. At this time, the sleeve plates 501 will correspond to the card slots 504 on the side walls of the fixed columns 403. Then rotate the drive column 503 between the two sleeve plates 501. Since the threads on the two lead screws 502 are arranged in opposite directions, when the drive column 503 is rotated, the two lead screws 502 drive the two sleeve plates 501 to move relatively. Then the two sleeve plates 501 will be clamped into the internal of the card slots 504 on the side walls of the two fixed columns 403, realizing the vertical limit of the sliding sleeve 404. At this time, the return pipe, the delivery pipe 303, the sliding sleeve 404 and the fixed column 403 form an I-shaped structure, increasing the stability between the delivery pipe 303 and the return pipe, avoiding shaking when one of them is repaired and affecting the loosening of the other and causing water leakage. And rotating the drive column 503 realizes the simultaneous movement of the two sleeve plates 501, realizing the horizontal fixation of the two fixed columns 403. At this time, the two nuts 302 will also be relatively squeezed, increasing the sealing performance between the fixed pipe 301 and the delivery pipe 303, avoiding water leakage; Since the delivery pipes 303 are all made of metal, the upper half of the whole device is connected to the incoming hot water inlet pipe, that is, the two delivery pipes 303 fix the whole device for the first time. The installation is the fixation. Then, the delivery pipe 303 on the right part, that is, the water outlet position, will be connected to the return water pipe. The return water pipe can be connected to the delivery pipe 303 through an elbow to form an L shape. Then a part of the return pipe will be parallel to the delivery pipe 303. Adjust the length of the sliding sleeve 404 to make the bottom plate 405 abut against the return pipe. This is the second fixation of the whole device. There is a repulsive expansion force between the heat meter body 1 and the bottom plate 405, so no matter which pipe, shaking can be avoided.
