Description

Technical Field

[0001] This application relates to the field of water meter measurement, and particularly to a low-cost multi-functional dry metal water meter structure. Background Art

[0002] A water meter is an essential instrument for measuring water consumption in the water pipes of each household. Since the water meter needs to withstand a large internal water pressure and has certain requirements for external protection, copper materials are mainly used as the outer shell of dry water meters at home and abroad.

[0003] In related technologies, referring to Figure 1 , the water meter mainly consists of a counter 1, a copper middle cover 11, and a first copper shell 12. The copper middle cover 11 realizes overall sealing by pressing the counter 1 with external threads, allowing water to flow inside the first copper shell 12. Since the copper middle cover 11 and the first copper shell 12 are made of metal materials, they have high pressure-bearing performance and are durable. Since the counter 1 is also wrapped in copper parts, the consumption of copper materials increases, and the product cost is high; when passing through a liquid with a higher temperature inside the first copper shell 12, since the heat conduction performance of the copper middle cover 11 and the first copper shell 12 is better than that of the plastic counter 1, the copper middle cover 11 and the first copper shell 12 will heat the periphery of the counter 1, and there will be a certain temperature difference between the copper middle cover 11, the first copper shell 12 and the counter 1, resulting in the air on the inner wall of the counter 1 condensing and liquefying at the top of the counter 1, and then the water droplets will fall on the internal structure of the counter 1, affecting the accuracy of the reading. Summary of the Invention

[0004] In order to reduce material costs and avoid the influence of condensate water generated on the inner wall of the counter due to temperature difference on the reading accuracy, this application provides a low-cost multi-functional dry metal water meter structure.

[0005] The low-cost multi-functional dry metal water meter structure provided by this application adopts the following technical solutions:

[0006] A low-cost multi-functional dry metal water meter structure includes a counter, including a second copper shell. The counter is arranged on the second copper shell. An installation groove for placing the counter is opened on the second copper shell. A threaded retaining ring is arranged at the end of the counter located in the installation groove. The threaded retaining ring is provided with a first thread, and the installation groove is provided with a second thread. The first thread is matched with the second thread. A metering box is arranged at the end of the counter located inside the second copper shell. A pressure plate is arranged between the metering box and the counter. A rubber gasket for improving the sealing performance of the second copper shell is arranged at the end of the pressure plate close to the threaded retaining ring. A plurality of ultraviolet disinfection lamps are arranged on the metering box.

[0007] By adopting the above technical solution, a threaded retaining ring and a mounting groove are provided on the counter and the second copper shell, and the pressure-bearing copper middle cover in the related art is removed, so that there is only one copper component, i.e., the second copper shell, in the whole water meter, reducing the copper material consumption of the water meter and the failure rate. At the same time, when high-temperature liquid passes through the second copper shell, the heat on the second copper shell can only affect the vicinity of the contact point between the counter and the second copper shell. Since the counter is made of plastic, only a small part of the heat at the contact point between the counter and the second copper shell is transferred to the vicinity of the counter dial, reducing the temperature difference between the counter dial and the air and the possibility of the counter dial fogging up. The ultraviolet disinfection lamp can disinfect the water flow entering and leaving the metering box.

[0008] Preferably, an impeller for detecting the flow rate is arranged in the metering box, the impeller is connected to the counter, and a cleaning assembly for cleaning the stains on the surface of the impeller is arranged in the second copper shell. The cleaning assembly includes a cleaning rod and a mounting plate. A plurality of the cleaning rods are slidably arranged on the mounting plate. The mounting plate is provided with a first sliding groove for slidingly cooperating with the cleaning rod. The cleaning rod slidably cooperates with the inner side wall of the first sliding groove. The end of the cleaning rod away from the mounting plate can penetrate into the metering box and slidably cooperate with the impeller. A second sliding groove for slidingly cooperating with the cleaning rod is provided on the side wall of the metering box close to the mounting plate. A first driving assembly for driving the mounting plate to move towards the metering box is arranged in the second copper shell.

[0009] By adopting the above technical solution, after the counter is used for a long time, a certain amount of stains will adhere to the surface of the impeller, affecting the normal operation of the impeller. The first driving assembly drives the mounting plate to move towards the metering box. The movement of the mounting plate causes the cleaning rod to move. The cleaning rod moves and penetrates into the metering box, thereby cleaning the impeller.

[0010] Preferably, the first driving assembly includes a motor and a first lead screw. The motor is arranged on the second copper shell. The output end of the motor is fixedly connected to the first lead screw. The first lead screw penetrates into the second copper shell and is rotatably connected to the second copper shell. A connecting rod is rotatably connected to the mounting plate. The end of the connecting rod away from the mounting plate is rotatably connected to a movable sleeve. The first lead screw penetrates into the movable sleeve and is in threaded cooperation with the movable sleeve. A limiting rod is slidably penetrated through the movable sleeve. The end of the limiting rod away from the movable sleeve is fixedly connected to the inner side wall of the second copper shell.

[0011] By adopting the above technical solution, when an operator needs to clean the impeller, the operator starts the motor, the motor drives the first lead screw to rotate, the rotation of the first lead screw causes the movable sleeve to move, the movement of the movable sleeve causes the connecting rod to move, the movement of the connecting rod causes the mounting plate to move, and the movement of the mounting plate causes the cleaning rod to move and insert into the metering box.

[0012] Preferably, a second driving component for driving the cleaning rod to move in the first chute is arranged on the mounting plate. The second driving component includes a second reciprocating lead screw and a first straight gear. The second reciprocating lead screw is rotatably installed on the side wall of the mounting plate close to the connecting rod. The second reciprocating lead screw penetrates into the end of the cleaning rod close to the connecting rod. The second reciprocating lead screw is in threaded cooperation with the cleaning rod. The first straight gear is fixedly sleeved on the end of the second reciprocating lead screw close to the connecting rod. A third driving component for driving the first straight gear to rotate is arranged in the second copper shell.

[0013] By adopting the above technical solution, the third driving component drives the first straight gear to rotate, the rotation of the first straight gear causes the second reciprocating lead screw to rotate, and the rotation of the second reciprocating lead screw causes the cleaning rod to move along the first chute on the mounting plate, so as to clean the surface of the impeller.

[0014] Preferably, the third driving component includes a crown gear and a second straight gear. The crown gear is fixedly sleeved on the end of the connecting rod close to the first straight gear. The crown gear meshes with the first straight gear. The second straight gear is fixedly sleeved on the end of the connecting rod close to the movable sleeve. A telescopic column is rotatably installed in the second copper shell. A third straight gear is fixedly sleeved at one end of the telescopic column, and a fourth straight gear is fixedly sleeved at the other end of the telescopic column. The third straight gear can mesh with the second straight gear. A sleeve is arranged on the side wall of the movable sleeve away from the connecting rod. A fifth straight gear is arranged at the end of the sleeve away from the movable sleeve. The fifth straight gear is rotatably connected with the sleeve. The fifth straight gear meshes with the fourth straight gear. A lifting plate is fixedly connected to the fifth straight gear. The lifting plate abuts against the fourth straight gear. A fixing component for clamping with the first lead screw is arranged on the fifth straight gear.

[0015] By adopting the above technical solution, after the motor drives the first lead screw to rotate and the movable sleeve moves to the highest height, during the process of the fifth straight gear following the movable sleeve, the lifting plate pushes the fourth straight gear upward so that the third straight gear meshes with the second straight gear, and the fixing component makes the fifth straight gear engage with the first lead screw. The first lead screw continues to rotate and cannot make the movable sleeve move. When the first lead screw rotates, it will make the fifth straight gear rotate. The rotation of the fifth straight gear makes the fourth straight gear rotate. The rotation of the fourth straight gear makes the telescopic column rotate. The rotation of the telescopic column makes the third straight gear rotate. The rotation of the third straight gear makes the connecting rod rotate. The rotation of the connecting rod makes the crown gear rotate. The rotation of the crown gear makes several first straight gears rotate simultaneously. Several second reciprocating lead screws rotate simultaneously, and the cleaning rod moves accordingly.

[0016] Preferably, the clamping component includes a clamping block and a first return spring. The clamping block is inserted through the fifth straight gear. A third chute for slidingly cooperating with the clamping block is formed on the fifth straight gear. The end of the clamping block located in the third chute is fixedly connected to the first return spring. The end of the first return spring away from the clamping block is fixedly connected to the inner end wall of the third chute. A clamping groove for cooperating with the clamping block is formed on the first lead screw. A slope is provided at the end of the clamping block close to the clamping groove.

[0017] By adopting the above technical solution, when the motor drives the first lead screw to rotate and the movable sleeve moves, the fifth straight gear follows the movable sleeve. When the fifth straight gear moves to the position of the clamping groove, the clamping block moves under the action of the first return spring and abuts against the inner side wall of the clamping groove. At this time, the rotation of the first lead screw can make the fifth straight gear rotate.

[0018] Preferably, a closing cover plate for closing the second chute is provided on the cleaning rod. The end of the cleaning rod away from the mounting plate is slidably engaged with the closing cover plate. A fourth chute for slidingly cooperating with the cleaning rod is formed on the closing cover plate. A limiting block is provided on the side wall of the closing cover plate away from the cleaning rod. A limiting groove for plugging and cooperating with the limiting block is formed on the inner side wall of the metering box.

[0019] By adopting the above technical solution, the closing cover can ensure the sealing of the metering box when the cleaning rod does not clean the impeller, preventing water leakage from the first chute and affecting the accuracy of the counter. When the motor drives the cleaning rod to be inserted into the metering box, the limiting block is inserted into the limiting groove. The third driving component drives the first straight gear to rotate. The rotation of the first straight gear makes the second reciprocating lead screw rotate. The rotation of the second reciprocating lead screw makes the cleaning rod move along the first chute on the mounting plate. The top end of the cleaning rod moves along the fourth chute, improving the stability of the cleaning rod.

[0020] Preferably, a check valve for preventing water backflow is provided at the output end of the second copper shell.

[0021] By adopting the above technical solution, when the water flow passes through the second copper shell from the input end to the output end, the blocking plate presses the second return spring, and at this time, the water flow normally passes through the second copper shell. When the water-using end stops using water, the water in the pipeline will flow back a certain distance, and the water flow flows from the output end of the second copper shell to the input end of the second copper shell. The water flow impacts the blocking plate to close the output end of the second copper shell, preventing the water flow from flowing back and affecting the reading of the counter.

[0022] Preferably, a filter screen is arranged inside the input end of the second copper shell.

[0023] By adopting the above technical solution, the filter screen is used to prevent impurities in the water flow flowing into the input end of the second copper shell from entering the metering box, thereby affecting the rotation of the impeller.

[0024] A hair electromagnet is arranged on the end of the impeller penetrating into the counter. A metal coil is arranged inside the counter. The hair electromagnet is located inside the metal coil. A storage battery is arranged inside the metering box.

[0025] When the water flow passes through the metering box and causes the impeller to rotate, the rotation of the impeller causes the hair electromagnet to rotate. The metal coil cuts the magnetic induction lines of the hair electromagnet to generate current. The storage battery is used to store the generated current to supply power to the motor, eliminating the need for an external power supply to supply power to the motor and improving the convenience of the device.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Threaded retaining rings and mounting grooves are arranged on the counter and the second copper shell, removing the pressure-bearing copper middle cover in the related art, so that there is only one copper component, the second copper shell, in the entire water meter, reducing the copper material consumption of the water meter, reducing the failure rate. At the same time, when high-temperature liquid passes through the second copper shell, the heat on the second copper shell can only affect the vicinity of the contact point between the counter and the second copper shell. Since the counter is made of plastic, only a small part of the heat at the contact point between the counter and the second copper shell is transferred to the vicinity of the counter dial, reducing the temperature difference between the counter dial and the air and reducing the possibility of the counter dial fogging;

[0028] 2. By arranging a cleaning component, the stains on the surface of the impeller can be quickly cleaned, preventing the rotation of the impeller from being affected by the accumulation of stains, thereby affecting the reading of the counter;

[0029] 3. By arranging a check component, the water flow can be prevented from flowing back and affecting the reading of the counter. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The implementation principle of a low-cost multi-functional dry metal water meter structure in an embodiment of the present application is as follows: Threaded retaining rings 13 and mounting grooves 21 are provided on the counter 1 and the second copper shell 2. The copper middle cover 11 that bears pressure in the related art is removed, so that there is only one copper component, i.e., the second copper shell 2, in the entire water meter, reducing the amount of copper material used in the water meter and the failure rate. At the same time, when high-temperature liquid passes through the second copper shell 2, the heat on the second copper shell 2 can only affect the vicinity of the contact point between the counter 1 and the second copper shell 2. Since the counter 1 is made of plastic, only a small part of the heat at the contact point between the counter 1 and the second copper shell 2 is transferred to the vicinity of the dial of the counter 1, reducing the temperature difference between the dial of the counter 1 and the air and the possibility of fogging on the dial of the counter 1.

[0056] When an operator needs to clean the impeller 25, the operator starts the motor 41. The motor 41 drives the first lead screw 42 to rotate. The first lead screw 42 rotates to make the movable sleeve 44 move. The movable sleeve 44 moves to make the connecting rod 43 move. The connecting rod 43 moves to make the mounting plate 32 move. The mounting plate 32 moves to make the cleaning rod 31 move and insert into the metering box 22. At this time, the limiting block on the closing cover plate 33 inserts into the limiting groove. At the same time, the fifth spur gear 58 rises following the movable sleeve 44. Under the action of the lifting plate 581, the fourth spur gear 57 and the third spur gear 56 rise.

[0057] When the movable sleeve 44 moves to the highest height, the motor 41 continues to rotate but will not make the movable sleeve 44 continue to move. The block 61 in the fifth spur gear 58 abuts against the card slot 612 under the action of the first return spring 62. The first lead screw 42 continues to rotate to make the fifth spur gear 58 rotate. The fifth spur gear 58 rotates to make the fourth spur gear 57 rotate. The fourth spur gear 57 rotates to make the telescopic column 55 rotate. The telescopic column 55 rotates to make the third spur gear 56 rotate. The third spur gear 56 rotates to make the second spur gear 54 rotate. The second spur gear 54 rotates to make the connecting rod 43 rotate. The connecting rod 43 rotates to make the crown gear 53 rotate. The crown gear 53 rotates to make the first spur gear 52 rotate. The second reciprocating lead screw 51 thus rotates, and the cleaning rod 31 thus moves along the length direction of the first chute 321 to clean the surface of the impeller 25.

[0058] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
