[0002] This device is a smart water meter that integrates mechanical metering, photoelectric conversion, and remote communication technologies. It is mainly used to accurately measure water consumption and realize remote data transmission.

[0003] Patent publication number CN217358631U relates to a rotary-blade dry-type electronic remote-reading photoelectric direct-reading water meter, comprising a water meter body, a pair of connecting pipes on the water meter body, and water pipes respectively installed on the pair of connecting pipes. An upper outer shell is provided at the upper end of the water meter body, and first fixing members are fixedly connected to both ends of the upper outer shell. A lower outer shell is provided at the lower end of the water meter body, and second fixing members are fixedly connected to both ends of the lower outer shell. A first observation port is opened on the upper outer shell, and a first glass plate matching the first observation port is fixedly connected to the upper outer shell. A filter layer is installed inside the water pipes. This patent, by providing an upper and lower outer shell on the outside of the rotary-blade water meter, reduces the possibility of external damage to the rotary-blade water meter, and greatly reduces the waste of water resources caused by the inlet or outlet of the rotary-blade water meter becoming detached from the water pipe.

[0004] The aforementioned patent reduces the possibility of external damage to the rotary water meter and greatly reduces the waste of water resources caused by the inlet or outlet of the rotary water meter being separated from the water pipe. When the rotary water meter needs to be repaired, the protective cover needs to be removed. Over time, the screws are prone to rust, affecting the repair efficiency. At the same time, the water pipe will continue to flow during the repair process, which may lead to problems such as water pipe leakage. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary-type photoelectric direct-reading remote water meter with an intelligent sensor to solve the problem of being difficult to open.

[0006] To achieve the above objectives, the present invention provides a rotary-blade photoelectric direct-reading remote water meter with an intelligent sensor, comprising: a base; a protective shell disposed above the base; a rotary-blade photoelectric direct-reading remote water meter body disposed on the top of the base, wherein a photoelectric direct-reading sensor is disposed on the rotary-blade photoelectric direct-reading remote water meter body, the photoelectric direct-reading sensor being used to send the read data to a remote meter reading system or cloud platform; a connecting pipe fixedly installed on the surface of the rotary-blade photoelectric direct-reading remote water meter body; and a fixing plate fixedly installed on the fixing plate.

[0007] In one or more embodiments of the present invention, a trapezoidal sliding plate is slidably mounted on the top of the protective shell, a connecting plate is fixedly mounted on the surface of the trapezoidal sliding plate, a sliding plate is slidably mounted on the top of the protective shell, a first spring is provided between the protective shell and the semi-circular sliding plate, and the semi-circular sliding plate is reset by the elastic force of the first spring, a second spring is provided between the protective shell and the trapezoidal block, and the trapezoidal block is reset by the elastic force of the second spring, a third spring is provided between the protective shell and the trapezoidal sliding plate, and the trapezoidal sliding plate is reset by the elastic force of the third spring, and a fourth spring is provided between the protective shell and the sliding plate, and the sliding plate is reset by the elastic force of the fourth spring. When the maintenance is completed and the semi-circular sliding plate needs to be closed, the trapezoidal block is pushed upward, the upward movement of the trapezoidal block will drive the limiting plate upward, and the upward movement of the limiting plate will contact the trapezoidal sliding plate.

[0008] In one or more embodiments of the present invention, the protective shell is provided with a cleaning device and a water shut-off device for cleaning the body of the rotary photoelectric direct-reading remote water meter. The cleaning device includes an elastic telescopic plate, a cleaning brush, a guide plate, and a sliding rod. Moving the semi-circular sliding plate away from the center of the protective shell will cause the elastic telescopic plate to move away from the center of the protective shell. The elastic telescopic plate is fixedly installed at the bottom of the semi-circular sliding plate, the cleaning brush is fixedly installed at the bottom of the elastic telescopic plate, the guide plate is fixedly installed on the inner wall of the protective shell, one end of the sliding rod is fixedly installed at the free end of the elastic telescopic plate, and the other end of the sliding rod is slidably installed on the inner wall of the guide plate.

[0009] In one or more embodiments of the present invention, a rotating plate is rotatably mounted on the surface of the guide plate, a fixing block is fixedly mounted on the surface of the rotating plate, a limit block is fixedly mounted on the surface of the guide plate, and a sliding rod moves upward along the groove on the inner wall of the guide plate. The upward movement of the sliding rod will cause the free end of the elastic telescopic plate to contract, and the contraction of the free end of the elastic telescopic plate will cause the cleaning brush to move upward.

[0010] In one or more embodiments of the present invention, a torsion spring is provided between the guide plate and the rotating plate, and the rotating plate is reset by the elastic force of the torsion spring itself, and the surface of the fixing block and the limiting block are in contact.

[0011] In one or more embodiments of the present invention, the water shut-off device includes a slider, a baffle, a push plate, a sliding frame, a sealing plate, a trapezoidal frame, and a ring. The sliding rod moves away from the center of the protective shell, causing the baffle to move away from the center of the protective shell. The movement of the baffle away from the center of the protective shell causes the slider and the push plate to move away from the center of the protective shell. The slider is slidably mounted on the bottom of the guide plate, the baffle is fixedly mounted on the top of the slider, the push plate is fixedly mounted on the bottom of the slider, the sliding frame is slidably mounted on the inner wall of the connecting pipe, the sealing plate is fixedly mounted on the bottom of the sliding frame, the trapezoidal frame is fixedly mounted on the top of the sliding frame, and the ring is fixedly mounted on the inner wall of the connecting pipe.

[0012] In one or more embodiments of the present invention, an L-shaped frame is fixedly installed on the surface of the sliding frame, an L-shaped plate is fixedly installed on the surface of the L-shaped frame, and a drain rod is fixedly installed at the bottom of the L-shaped plate. When the sliding frame moves downward, it will drive the L-shaped frame to move downward, the L-shaped frame to move downward, the L-shaped plate to move downward, and the drain rod to move downward.

[0013] In one or more embodiments of the present invention, a No. 5 spring is provided between the slider and the guide plate, and the slider is reset by the elastic force of the No. 5 spring itself. A No. 6 spring is provided between the sliding frame and the connecting pipe, and the sliding frame is reset by the elastic force of the No. 6 spring itself. The sealing plate is in contact with the surface of the ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention opens the top of the rotary photoelectric direct-reading remote water meter body by moving the semi-circular sliding plate away from the center of the protective shell, facilitating maintenance. The trapezoidal block resets and blocks the short plate, preventing the first spring from causing the semi-circular sliding plate to rebound and affecting normal maintenance. The trapezoidal sliding plate limits the position of the limiting plate, eliminating the need to pull the short rod with one finger, making operation more convenient. At the same time, moving the trapezoidal sliding plate away from the limiting plate will disengage it from the limiting plate, allowing the second spring's own elasticity to reset the trapezoidal block, facilitating subsequent maintenance operations.

[0015] This invention uses a cleaning brush that moves away from the center of the protective casing to push away dust from the surface of the water meter, preventing dust from adhering and affecting the observer's observation. At the same time, the retraction of the free end of the elastic telescopic plate will cause the cleaning brush to move upward. As the cleaning brush moves upward, it will detach from the water meter, preventing the dust adhering to the surface of the cleaning brush from being re-applied to the water meter and affecting the observer's observation.

[0016] This invention utilizes a push plate that moves away from the center of the protective shell to push a trapezoidal frame downwards. The downward movement of the trapezoidal frame causes the sliding frame and sealing plate to move downwards. The downward movement of the sealing plate seals the ring, preventing continuous water flow through the connecting pipe during maintenance, which could lead to water leakage during disassembly and maintenance, thus affecting normal maintenance. The downward movement of the unblocking rod unblocks the drain hole, preventing impurities from clogging the drain hole when the pipe leaks, thus preventing water from accumulating inside the protective shell and affecting drainage efficiency.

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figure 1 - Figure 7 As shown, one embodiment of the present invention is: a rotary-type photoelectric direct-reading remote water meter containing an intelligent sensor, comprising: a base 1, a protective shell 2, the protective shell 2 being disposed above the base 1; a rotary-type photoelectric direct-reading remote water meter body 3, the rotary-type photoelectric direct-reading remote water meter body 3 being disposed on the top of the base 1, the rotary-type photoelectric direct-reading remote water meter body 3 being provided with a photoelectric direct-reading sensor, the photoelectric direct-reading sensor being used to send the read data to a remote meter reading system or cloud platform; a connecting pipe 4, the connecting pipe 4 being fixedly installed on the surface of the rotary-type photoelectric direct-reading remote water meter body 3; and a fixing plate 5, the fixing plate 5 being... The base 1 and the protective shell 2 are fixedly installed on the surface; bolt 6 is threaded onto the inner wall of the fixing plate 5; a drain pipe is provided at the bottom of the base 1; a semi-circular sliding plate 7 is slidably installed on the inner wall of the protective shell 2; an L-shaped push plate 8 is fixedly installed on the top of the semi-circular sliding plate 7; a short plate 9 is fixedly installed on the surface of the L-shaped push plate 8; a trapezoidal block 10 is slidably installed on the top of the protective shell 2; a short rod 11 is fixedly installed on the top of the trapezoidal block 10; a limit plate 12 is slidably installed on the surface of the trapezoidal block 10; by moving the semi-circular sliding plate 7 away from the middle of the protective shell 2, the top of the rotary photoelectric direct-reading remote water meter body 3 is opened, which is convenient for maintenance.

[0021] A trapezoidal sliding plate 13 is slidably mounted on the top of the protective shell 2. A connecting plate 14 is fixedly mounted on the surface of the trapezoidal sliding plate 13. A sliding plate 15 is slidably mounted on the top of the protective shell 2. A first spring is provided between the protective shell 2 and the semi-circular sliding plate 7. The semi-circular sliding plate 7 is reset by the elastic force of the first spring. A second spring is provided between the protective shell 2 and the trapezoidal block 10. The trapezoidal block 10 is reset by the elastic force of the second spring. A third spring is provided between the protective shell 2 and the trapezoidal sliding plate 13. The trapezoidal sliding plate 13 is reset by the elastic force of the third spring. A fourth spring is provided between the protective shell 2 and the sliding plate 15. The sliding plate 15 is reset by the elastic force of the fourth spring. The trapezoidal sliding plate 13 limits the position of the limiting plate 12, eliminating the need to pull the short rod 11 with one finger, making operation more convenient.

[0022] In this embodiment, during operation: When maintenance is required on the rotor-type photoelectric direct-reading remote water meter body 3, the L-shaped push plate 8 is pushed away from the center of the protective shell 2. This movement causes the semi-circular sliding plate 7 to move away from the center of the protective shell 2, opening the top of the rotor-type photoelectric direct-reading remote water meter body 3 for easier maintenance. Simultaneously, the movement of the L-shaped push plate 8 away from the center of the protective shell 2 causes the short plate 9 to move away from the center of the protective shell 2. The short plate 9 then contacts the trapezoidal block 10. After the short plate 9 disengages from the trapezoidal block 10, the elastic force of the second spring causes the trapezoidal block 10 to reset. This reset of the trapezoidal block 10 blocks the short plate 9, preventing the first spring from causing the semi-circular sliding plate 7 to rebound and interfere with normal maintenance. When maintenance is complete and the semi-circular sliding plate 7 needs to be closed, the trapezoidal block 10 is pushed away from the center of the protective shell 2. When the trapezoidal block 10 moves upward, it causes the limiting plate 12 to move upward. The limiting plate 12 then contacts the trapezoidal slide plate 13, which pushes the trapezoidal slide plate 13 away from the limiting plate 12. After the limiting plate 12 disengages from the trapezoidal slide plate 13, the elastic force of the third spring causes the trapezoidal slide plate 13 to reset. The trapezoidal slide plate 13 limits the limiting plate 12, eliminating the need to pull the short rod 11 with one finger, making operation more convenient. At the same time, during the process of the L-shaped push plate 8 driving the short plate 9 to reset, it pushes the sliding plate 15 upward. The upward movement of the sliding plate 15 pushes the connecting plate 14 away from the limiting plate 12. The movement of the connecting plate 14 away from the limiting plate 12 causes the trapezoidal slide plate 13 to move away from the limiting plate 12. The movement of the trapezoidal slide plate 13 away from the limiting plate 12 causes it to disengage from the limiting plate 12, allowing the elastic force of the second spring to reset the trapezoidal block 10, facilitating subsequent maintenance operations.

[0023] Please see Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, the protective shell 2 is provided with a cleaning device and a water shut-off device for cleaning the rotor-type photoelectric direct-reading remote water meter body 3. The cleaning device includes an elastic telescopic plate 161, a cleaning brush 162, a guide plate 163, and a sliding rod 164. The elastic telescopic plate 161 is fixedly installed at the bottom of the semi-circular sliding plate 7, the cleaning brush 162 is fixedly installed at the bottom of the elastic telescopic plate 161, the guide plate 163 is fixedly installed on the inner wall of the protective shell 2, one end of the sliding rod 164 is fixedly installed at the free end of the elastic telescopic plate 161, and the other end of the sliding rod 164 is slidably installed on the inner wall of the guide plate 163. By moving the cleaning brush 162 away from the center of the protective shell 2, the dust on the surface of the water meter is pushed away, preventing dust from adhering and affecting the observation of the testing personnel.

[0024] A rotating plate 165 is rotatably mounted on the surface of the guide plate 163, and a fixing block 166 is fixedly mounted on the surface of the rotating plate 165. A limit block 167 is fixedly mounted on the surface of the guide plate 163. When the cleaning brush 162 moves upward, it will disengage from the water meter to prevent the dust adhering to the surface of the cleaning brush 162 from being re-applied to the water meter and affecting the observation by the testing personnel.

[0025] A torsion spring is provided between the guide plate 163 and the rotating plate 165. The rotating plate 165 is reset by the elastic force of the torsion spring itself, and the fixed block 166 contacts the surface of the limiting block 167.

[0026] In this embodiment, during operation: the semi-circular sliding plate 7 moves away from the center of the protective shell 2, causing the elastic telescopic plate 161 to move away from the center of the protective shell 2. This movement of the elastic telescopic plate 161 further away from the center of the protective shell 2 causes the cleaning brush 162 to move away from the center of the protective shell 2, pushing away dust from the water meter surface and preventing dust from affecting the observer's observation. Simultaneously, the movement of the elastic telescopic plate 161 away from the center of the protective shell 2 causes the sliding rod 164 to slide along the guide plate 163. During this sliding process, the sliding rod 164 contacts the rotating plate 165, pushing the rotating plate 165. When the rotating plate 165 is rotated downwards, after it disengages from the sliding rod 164, the elastic force of the first torsion spring will cause the rotating plate 165 to reset. The reset of the rotating plate 165 will limit the sliding rod 164, and at the same time, the limiting block 167 will limit the fixing block 166. When the semi-circular sliding plate 7 resets, the sliding rod 164 will move upwards along the groove on the inner wall of the guide plate 163. The upward movement of the sliding rod 164 will cause the free end of the elastic telescopic plate 161 to retract. The retraction of the free end of the elastic telescopic plate 161 will cause the cleaning brush 162 to move upwards. The upward movement of the cleaning brush 162 will disengage from the water meter, preventing the dust adhering to the surface of the cleaning brush 162 from being re-applied to the water meter and affecting the observation by the testing personnel.

[0027] The water shut-off device includes a slider 171, a baffle 172, a push plate 173, a sliding frame 174, a sealing plate 175, a trapezoidal frame 176, and a ring 177. The slider 171 is slidably mounted on the bottom of the guide plate 163, the baffle 172 is fixedly mounted on the top of the slider 171, the push plate 173 is fixedly mounted on the bottom of the slider 171, the sliding frame 174 is slidably mounted on the inner wall of the connecting pipe 4, the sealing plate 175 is fixedly mounted on the bottom of the sliding frame 174, the trapezoidal frame 176 is fixedly mounted on the top of the sliding frame 174, and the ring 177 is fixedly mounted on the inner wall of the connecting pipe 4. This device prevents continuous water flow through the connecting pipe 4 during maintenance, which could lead to water leakage during disassembly and maintenance, thus affecting normal maintenance.

[0028] An L-shaped frame 178 is fixedly installed on the surface of the sliding frame 174. An L-shaped plate 179 is fixedly installed on the surface of the L-shaped frame 178. A drain rod 1710 is fixedly installed at the bottom of the L-shaped plate 179. The drain rod 1710 moves downward to the drain hole to clear the blockage. This prevents the drain hole from being blocked by impurities when the pipe leaks, which would cause water to accumulate inside the protective shell 2 and affect the drainage efficiency.

[0029] A No. 5 spring is provided between the slider 171 and the guide plate 163. The slider 171 is reset by the elastic force of the No. 5 spring. A No. 6 spring is provided between the sliding frame 174 and the connecting pipe 4. The sliding frame 174 is reset by the elastic force of the No. 6 spring. The sealing plate 175 is in contact with the surface of the ring 177.

[0030] The sliding rod 164 moves away from the center of the protective shell 2, causing the pusher baffle 172 to move away from the center of the protective shell 2. This movement of the baffle 172 further away from the center of the protective shell 2 causes the slider 171 and pusher plate 173 to move away from the center of the protective shell 2. The pusher plate 173's movement away from the center of the protective shell 2 pushes the trapezoidal frame 176 downwards. This downward movement of the trapezoidal frame 176 causes the sliding frame 174 and sealing plate 175 to move downwards. The downward movement of the sealing plate 175 then moves the ring 177 downwards. The system is sealed to prevent continuous water flow through the connecting pipe 4 during maintenance, which could lead to water leakage during disassembly and maintenance, affecting normal maintenance. At the same time, when the sliding frame 174 moves downward, it will drive the L-shaped frame 178 to move downward. The downward movement of the L-shaped frame 178 will drive the L-shaped plate 179 to move downward. The downward movement of the L-shaped plate 179 will drive the drain rod 1710 to move downward. The downward movement of the drain rod 1710 will clear the drain hole, preventing the drain hole from being blocked by impurities when the pipe leaks, which would cause water to accumulate inside the protective shell 2 and affect drainage efficiency.
