[0035] The present invention provides the following technical solutions: a self-generating remote water meter, comprising a housing 1, wherein a measuring unit 5, an adjusting component 11 and a rotating component 13 are arranged in the housing 1; the adjusting component 11 comprises a conical drain pipe 116, and the drain pipe 116 is used to adjust the water pressure of the water flow; through the design of the conical drain pipe 116, the water flow in the water meter is smoothly sprayed toward the driving blade 132, thereby driving the driving blade 132 to rotate and generate electricity, and when the water flow in the water meter is too small, the water flow is concentrated in one place and sprayed toward the driving blade 132 to generate electricity. The power generation operation has higher utilization efficiency. The rotating component 13 includes three driving blades 132. The driving blades 132 rotate in cooperation with the drain pipe 116 to discharge water. The top of the outer shell 1 is connected to the cylinder 6 and the protective shell 12. A power generation component 14 is arranged on one side of the protective shell 12. Rebound components 15 are arranged on the front and rear sides of the protective shell 12. The power generation component 14 includes a piezoelectric ceramic 142. The piezoelectric ceramic 142 vibrates to generate current. The rebound component 15 includes a second spring 153. The second spring 153 rebounds the piezoelectric ceramic 142.

[0036] Specifically, a water inlet 2 is provided on one side of the shell 1, and a water outlet 3 is provided on the other side of the shell 1. The water inlet 2 and the water outlet 3 are both connected to a fixing seat 4. A sealing cover 8 is rotatably connected to one side of the top of the cylinder 6. An external antenna 9 is connected to one side of the cylinder 6. The adjustment component 11 includes an annular support frame 111. An airbag 112, a first push plate 113 and a second push plate 118 are provided in the support frame 111. The first push plate 113 and the second push plate 118 are respectively connected to the two sides of the airbag 112. The other side of the first push plate 113 is connected to a first push rod 114. The other end of the first push rod 114 passes through the support frame 111 and is connected to a pressing plate 115. One end of a drain pipe 116 is connected to the pressing plate 115. The pipe 116 is located in the support frame 111, and a plurality of first springs 117 are arranged between the pressure plate 115 and the support frame 111. A plurality of second push rods 119 are connected to the other side of the second push plate 118. The other ends of the plurality of second push rods 119 pass through the other side of the support frame 111 and are rotatably connected to the rotating frame 1111. A plurality of arc-shaped baffles 1110 are arranged at the other end of the drain pipe 116. The plurality of baffles 1110 can form a conical whole. The other ends of the plurality of rotating frames 1111 are rotatably connected to one side of the plurality of baffles 1110 respectively. Through the cooperation of the limiting plate 10, the water flow entering the water meter can smoothly enter the drain pipe 116. Through the limiting of the rotating frame 1111, the plurality of baffles 1110 form a complete The water flow can be discharged at the middle position of the plurality of baffles 1110 through the limiting of the baffle 1110, so that the water flow can be ejected toward the driving blade 132 at the center position, so that the water flow can better contact the driving blade 132, driving the driving blade 132 to rotate. When the water flow in the water meter is too large, the water pressure in the drain pipe 116 becomes larger, and the impact pressure exerted by the water flow on the baffle 1110 becomes larger. At this time, due to the support of the rotating frame 1111, the drain pipe 116 and the plurality of baffles 1110 at one end are integrated as a whole, which will push the drain pipe 116 to move in the direction of the driving blade 132, drive the pressure plate 115 to move to one side of the support frame 111, and exert pressure between the pressure plate 115 and the support frame 111. The first spring 117 between the support frame 111 and the first spring 117 is squeezed to make the first spring 117 elastically deformed. When the pressure plate 115 approaches the support frame 111, the first push rod 114 is pushed to push the first push plate 113 in the support frame 111, and the air bag 112 in the support frame 111 is squeezed. The second push plate 118 is pushed evenly by the air bag 112. The second push plate 118 is evenly stressed, so that the second push plate 118 is translated in the direction close to the driving blade 132, thereby driving the second push rod 119 on the other side to slide out on the other side of the support frame 111. However, the force generated by squeezing the air bag 112 to push the second push plate 118 is much smaller than the impact force of the water flow on the drain pipe 116 itself.Therefore, the speed at which the second push plate 118 drives the second push rod 119 to extend at the other end is lower than the moving speed of the drain pipe 116 itself, and the moving distance of the second push rod 119 is shorter. The second push plate 118 is limited by the support frame 111, so the rotating frame 1111 will generate a pulling force on the baffle 1110, so that the multiple baffles 1110 are twisted on one end of the drain pipe 116 close to the driving blade 132. The baffle 1110 is a twistable rubber material. The multiple baffles 1110 twist away from each other. Through the multiple baffles 1110 moving away from each other, Thus, the inner diameter of the water conveyance is enlarged, and gaps are also generated between the multiple baffles 1110, so that drainage operation can also be performed. While the driving blade 132 is kept rotating under force, the water flow is prevented from causing a large pressure on the drain pipe 116, thereby affecting the basic function of the water meter. When the water flow decreases, the pressure on the inner wall of the drain pipe 116 is reduced, so that the force on the first push plate 114 is reduced, the air bag 112 rebounds, and the second push rod 114 is retracted. In addition, through the rebound effect of the baffle 1110 made of rubber material, the multiple baffles 1110 are brought closer to each other, restored, and reassembled. The outer shell 1 is formed into a complete cone, and the water flow is guided to facilitate full use of the water flow, and the driving blade 132 is pushed. The inner wall of the outer shell 1 is connected with an annular limit plate 10, and the limit plate 10 is located between the measuring unit 5 and the adjusting component 11. The inner diameter of the limit plate 10 gradually decreases from the side away from the adjusting component 11 to the side close to the adjusting component 11. The inner diameter of the limit plate 10 close to the measuring unit 5 is gradually reduced from the inner diameter of the limit plate 10 close to the measuring unit 5 to the inner diameter of the limit plate 10 close to the measuring unit 5. The water flow entering the water meter is guided so that the water flow can smoothly enter the drain pipe 116. In order to cooperate with the subsequent ejection of the driving blade 132, the driving blade 132 is rotated to guide the transported water flow. The rotating assembly 13 includes a rotating shaft 131, which is rotatably connected to the top of the inner wall of the shell 1. The three driving blades 132 are all connected to the surface of the rotating shaft 131 and cooperate with the water outlet end of the drain pipe 116. The top of the rotating shaft 131 passes through the shell 1 and is located in the protective shell 12. The outer surface of the rotating shaft 131 is connected to a fixing sleeve 133, and the outer surface of the fixing sleeve 133 is connected to a plurality of paddles 134, and the plurality of paddles 134 are all located in the protective shell 12;

[0037] During hydroelectric power generation, water is generally flushed on the driving blades 132 to drive the driving blades 132 to rotate and generate electricity. However, when the water flow in the water meter is small, the driving blades 132 cannot be pushed or are pushed slowly, resulting in failure to generate electricity or low power generation efficiency. When the water flow in the water meter is too large, the driving blades 132 will be impacted and damaged. Therefore, in order to make the rotation efficiency of the driving blades 132 within the optimal range of power generation, N = A*{Q / 3 / 4D1-D2*K}, N represents the rotation rate of the driving blades 132 (the range is 550-1070 rpm), Q represents the water flow in the water meter (the maximum value of the range is the maximum water flow that the water meter can convey), and The maximum value is 0, and the minimum value is 0. At this time, there is no water flow in the water meter and power generation cannot be performed), D1 is the water inlet diameter of the drain pipe 116 (the value range is 5.5-8.3cm), D2 is the water outlet diameter of the drain pipe 116 (the value range is 2.3-4.2cm), K represents the coefficient of the second spring 153 (the value range is 20.3-35.5N / m), and A is the adjustment coefficient (the value range is 3.375-7.855). By making the water inlet diameter and the water outlet diameter of the drain pipe 116 within the value range and then cooperating with the spring, the driving blade 132 can be within the optimal rotation range, so that the efficiency of self-generation is higher; the above formula only performs numerical calculations.

[0040] Specifically, the power generation component 14 includes a mounting seat 141, the mounting seat 141 is connected to one side of the inner wall of the protective shell 12, one side of the piezoelectric ceramic 142 is connected to the mounting seat 141, the piezoelectric ceramic 142 cooperates with a plurality of paddles 134, both sides of the piezoelectric ceramic 142 are connected to terminals 143, both terminals 143 are connected to wires 144, the bottom of the inner wall of the cylinder 6 is connected to a lithium battery pack 7, the other ends of the two wires 144 pass through the protective shell 12 and are connected to the lithium battery pack 7, and the two wires 144 are provided with a converter 145, and the rebound component 15 includes a support seat 151, a support The support seat 151 is connected to one side of the inner wall of the protective shell 12. A storage groove 152 is opened on the side of the support seat 151 close to the piezoelectric ceramic 142. The second spring 153 is connected to one side of the storage groove 152. The other end of the second spring 153 passes through the storage groove 152 and is connected to the stopper 154. When the piezoelectric ceramic 142 is pushed, the stopper 154 is pushed by the second spring 153 to block the piezoelectric ceramic 142 so that the piezoelectric ceramic 142 can be reset, thereby continuing to shake and perform power generation operations. The stopper 154 cooperates with the piezoelectric ceramic 142, and a nameplate 16 is connected to the front of the shell 1.

[0041] Working principle and use process of the present invention: When the present invention is in use, the staff can know the model of the water meter and the precautions when using it through the nameplate 16, which is convenient for the staff to perform installation operations. The staff adjusts the direction according to the water inlet end 2 and the water outlet end 3 of the water meter, connects the water inlet end 2 to the water outlet end 3 of a section of water pipe, and connects the water outlet end 3 to the water inlet end 2 of another section of water pipe. During installation, the fixing bolts are installed on the fixing seat 4 to tighten and fix them. After the seal is completed, the water meter is placed for use. When in use, the water flow in the water pipe enters the water meter through the water inlet end 2 of the water meter, and is powered by the lithium battery pack 7 in the cylinder 6, so that the measuring unit 5 in the shell 1 starts to work, and the flow rate and flow of the water flow are measured. The water after measurement The water flows through the blocking limit of the limit plate 10 and is guided into the drain pipe 116. The pressure plate 115 cooperates with the drain pipe 116 so that the water can be discharged at one end of the drain pipe 116 connected to the baffle 1110. The special design of the baffle 1110 increases the water pressure during the transportation process. The end of the drain pipe 116 with a smaller inner diameter is aligned with the driving blade 132, which is convenient for pushing the driving blade 132 to rotate in the housing 1. The rotation utilization efficiency is higher, and the water can be discharged at the middle position of multiple baffles 1110 through the limit of the rotating frame 1111, so that the driving blade 132 is sprayed, thereby driving the driving blade 132 to rotate. When the water pressure in the water meter is too high, the baffle 1110 is pressed. The applied pressure increases, pushing the drain pipe 116 to move toward the side of the driving blade 132, driving the pressure plate 115 to move toward the side of the support frame 111, squeezing the first spring 117 between the pressure plate 115 and the support frame 111, causing the first spring 117 to undergo elastic deformation. When the pressure plate 115 approaches the support frame 111, the first push rod 114 is pushed to push the first push plate 113 in the support frame 111, squeezing the airbag 112 in the support frame 111, and pushing the second push plate 118 through the airbag 112, so that the second push plate 118 moves toward the side of the driving blade 132, so that the second push rod 119 slides out from the other side of the support frame 111, and the second push plate 118 is limited by the support frame 111. The airbag 112 cooperates with the drain pipe 116 to generate a distance difference between the drain pipe 116 and the second push rod 119, thereby driving the rotating frame 1111 to pull the baffle 1110, so that the multiple baffles 1110 are away from each other, thereby expanding the inner diameter of the water conveyance, avoiding water flow blockage in the drain pipe 116, and making the driving blade 132 within the optimal rotation range, without affecting the basic conveying function of the water meter. When the flow in the housing 1 decreases, the squeezed and deformed first spring 117 rebounds and pushes the pressure plate 115 to reset. The pressure plate 115 drives the first push plate 113 to move in the opposite direction in the support frame 111, and no longer squeezes the airbag 112, so that the second push plate 118 is no longer subjected to the pressure of the airbag 112, and drives the rotating frame 1111 to reset.The plurality of baffles 1110 are reset at one end of the drain pipe 116 to limit the water flow, so that the driving blades 132 maintain working efficiency and perform power generation operation;

[0042] The driving blade 132 is impacted by the water flow, so that the driving blade 132 rotates under the continuous impact of the water flow, driving the rotating shaft 131 to rotate at the top of the inner wall of the shell 1, driving the paddle 134 to rotate in the protective shell 12, and the paddle 134 rotates. When the paddle 134 rotates to the side close to the piezoelectric ceramic 142, one paddle 134 first contacts the piezoelectric ceramic 142, and the piezoelectric ceramic 142 is pushed to move during the continuous rotation of the piezoelectric ceramic 134 until the other side of the piezoelectric ceramic 142 contacts the stopper 154, and the second spring 153 is squeezed by the piezoelectric ceramic 142, so that the second spring 153 is elastically deformed in the storage groove 152. Since one side of the piezoelectric ceramic 142 is fixed on the mounting seat 141, the piezoelectric ceramic 142 is separated from the piezoelectric ceramic during the continuous rotation of the paddle 134. Porcelain 142, after the paddle 134 is separated from the piezoelectric ceramic 142, the piezoelectric ceramic 142 is no longer subjected to the thrust, at this time, the second spring 153 generates a reverse force to push the stopper 154 to move, and the stopper 154 generates a reverse thrust on the piezoelectric ceramic 142 to push the piezoelectric ceramic 142 to reset, and during the continuous rotation of the shaft 131, the latter paddle 134 rotates to contact the piezoelectric ceramic 142, and pushes the piezoelectric ceramic 142 again, thereby reciprocating to make the piezoelectric ceramic 142 shake on the mounting seat 141, and during the shaking of the piezoelectric ceramic 142, the current passes through the terminal 143, enters the wire 144, and is converted by the converter 145 to charge the lithium battery pack 7, thereby completing the self-generation operation of the water meter, which can ensure the continuous use of the water meter and reduce maintenance operations.
