Description

Technical Field

[0001] The utility model relates to a water meter, in particular to an intelligent water meter with an automatically locked protective cover. Background Art

[0002] At present, the protective covers of water meters are all manually switched and have no locking function, resulting in that most of the protective covers of water meters in daily use are not in a closed and protective state. Abnormal problems caused by the protective cover not being in a closed and protective state are as follows:

[0003] A. Due to the lack of protection of the protective cover, the meter glass is often broken by artificial knocking, resulting in abnormal water use of users and property losses caused by water leakage.

[0004] B. Due to the lack of protection of the protective cover, the water meter is exposed to the sun and dust for a long time, which easily accelerates the aging of the internal metering components of the water meter, and at the same time, it is easy to cause abnormal situations such as the growth of moss, resulting in abnormal metering and reading of the water meter.

[0005] C. Due to the lack of protection of the protective cover, some new material meter glasses (such as resin material meter glasses) are easily scratched and aged by people due to long-term exposure, resulting in abnormal meter reading of the water meter, and even abnormal situations where the meter cannot be read.

[0006] D. Due to the lack of protection of the protective cover, the anti-freezing ability of the water meter is reduced, and it is easy to have abnormalities and property losses caused by water leakage. The frozen water meter glass bursts, resulting in abnormal water use of users and property losses caused by water leakage. Content of the Utility Model

[0037] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0038] Please refer to Figure 1 and Figure 2 As shown, an intelligent water meter with an automatically locked protective cover includes a base meter 1 and a module box 2. The module box 2 is fixed on the top of the base meter 1 and internally provided with a battery pack 4 and a circuit board 5. The battery pack 4 and the circuit board 5 are electrically connected. A protective cover 3 is hinged on one side of the module box 2. A motor 6 is provided inside the module box 2, and a lock rod bin 21 is provided inside the module box 2. A lock rod 7 is slidably arranged in the lock rod bin 21. A transmission mechanism is provided between the lock rod 7 and the motor 6, so that the motor 6 can drive the lock rod 7 to slide in the lock rod bin 21. One side of the protective cover 3 away from the motor 6 is hinged to the module box 2, and a lock hole 31 is opened on the side close to the motor 6. One end of the lock rod 7 extends out of the module box 2 and is inserted into the lock hole 31, thereby locking the protective cover 3.

[0039] To prevent the staff from forgetting to lock the protective cover 3, a photosensitive device 8 is provided at a position on the outer wall of the module box 2 close to the protective cover 3. The photosensitive device 8 and the motor 6 are both electrically connected to the circuit board 5. When the protective cover 3 blocks the photosensitive device 8 (i.e., in the closed cover state), the circuit board 5 can automatically control the motor 6 to push out the lock rod 7 to lock the protective cover 3.

[0040] For convenient control, this water meter further includes a remote transmission module, which is electrically connected to the circuit board 5, enabling the water meter to upload the locking situation of the protective cover 3 to the background or lock the protective cover 3 remotely.

[0041] To further monitor the locking situation of the protective cover 3, a buzzer is also included, which is electrically connected to the circuit board 5. When the protective cover 3 blocks the photosensitive device 8 (i.e., in the closed cover state), the circuit board 5 can activate the buzzer to remind nearby personnel to avoid forgetting to lock.

[0042] In one of the embodiments, the transmission mechanism is a gear-rack structure. Specifically, a gear is fixed to the output end of the motor 6, one side of the lock rod 7 is toothed and meshes with the gear. The motor 6 controls the rotation of the gear, and through the meshing of the gear and the rack, the lock rod 7 can move back and forth to achieve unlocking and locking.

[0043] In another embodiment, the transmission mechanism is a lever structure, specifically as Figure 3 shown - an eccentric lever 9 is fixedly mounted at the output end of the motor 6, a sliding groove 71 is formed on the locking lever 7, and the end of the lever 9 is movably embedded in the sliding groove 71; when the motor 6 drives the lever 9 to move along an arc, the lever 9 moves up and down in the sliding groove 71 and drives the locking lever 7 to move left and right to realize unlocking and locking.

[0044] It is worth mentioning that a number of limiting grooves are provided on the surface of the locking lever 7, and limiting blocks adapted to the limiting grooves are provided on the inner wall of the locking lever bin 21, so that the locking lever 7 only moves back and forth in a straight line to avoid rotation and inability to cooperate with the motor 6.

[0045] It can be understood that stop blocks are provided at both ends of the locking lever 7 to prevent it from falling out.

[0046] The principle of the present utility model is as follows:

[0047] A. The water meter reading is carried out by professional personnel or users. The unlocking function of the meter protection cover 3 is only given to the meter readers and users (which can be realized through special magnetic cards, the background or secret commands, etc.). In daily situations, the meter protection cover 3 is in a locked state. When it is necessary to read the basic reading of the water meter, the authorized personnel can issue an unlocking command for the protection cover 3;

[0048] B. After the authorized personnel issue an unlocking command for the protection cover 3, the motor 6 starts to operate and drives the locking lever 7 to retract into the locking lever bin. At this time, the protection cover 3 can be opened for water meter reading;

[0049] C. After the authorized personnel unlock and read the meter, the protection cover 3 should be closed in place. At this time, the photosensitive device 8 conducts to the circuit board 5, and the circuit board 5, according to the software instruction, makes the motor 6 start to operate and drive the locking lever 7 to extend out to lock the protection cover 3. When the protection cover 3 is not in place or has not been closed for a long time (possibly damaged by humans), the circuit board 5 can give a buzzer reminder or a background alarm according to the information conducted by the photosensitive device 8.

[0050] The above are only preferred embodiments of the present utility model, and do not limit the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
