DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 13 As shown, this embodiment proposes an anti-theft protection type Internet of Things water meter, including a water meter body 1, and also includes a base frame 2, a mounting frame 3, a top shell 4, a fixing component, a mounting component, an alarm component and a locking component. The mounting frame 3 is detachably mounted on the base frame 2, and the water meter body 1 is mounted on the mounting frame 3. The top shell 4 is detachably mounted on the mounting frame 3. The fixing component is mounted on the base frame 2 for fixing the position of the base frame 2. The fixing component includes a positioning hole 5 and an expansion screw 6. A plurality of positioning holes 5 are evenly spaced at the edge of the base frame 2, and a plurality of expansion screws 6 are arranged in each positioning hole 5, wherein the observation window 34 is installed on the top shell 4.

[0023] Specifically, when installing the water meter body 1, first install the base frame 2 in the working position. After the base frame 2 is placed in the working position, screw the expansion screws 6 on the positioning holes 5 into the working positions in sequence to fix the base frame 2. Then, the mounting frame 3 is installed on the base frame 2 through the mounting assembly, and the water meter body 1 is installed on the mounting frame 3. The port of the water meter body 1 is connected to the water pipe. At this time, the water meter body 1 is in contact with the alarm assembly. Then, the top shell 4 is placed on the mounting frame 3, and the locking assembly is started to fix the position of the top shell 4. When it is necessary to observe the water meter body 1, the value on the water meter body 1 can be observed through the observation window 34. Through the setting of the mounting assembly, it is difficult for non-staff to open the top shell 4 and the mounting frame 3. At the same time, through the setting of the alarm assembly, when there are criminals stealing the water meter body 1 or modifying the water meter body 1, the possibility of the water meter body 1 being stolen or modified can be reduced.

[0024] like Figures 5 to 8 As shown, the mounting assembly is installed on the mounting frame 3 and is used to fix the position between the mounting frame 3 and the base frame 2. The mounting assembly includes mounting ears 7, fastening screws 8, a fixing portion, a locking portion and a disconnecting portion. The four corners of the mounting frame 3 are fixedly installed with mounting ears 7, and the four mounting ears 7 are threadedly provided with fastening screws 8 inside. The fixing portion is installed on the mounting frame 3 and is used to determine the position of the mounting frame 3. The locking portion is installed inside the fixing portion and is used to fix the position between the fixing portion and the mounting frame 3. The disconnecting portion is installed inside the locking portion and is used to disconnect the connection between the mounting frame 3 and the fixing portion when the mounting frame 3 is disassembled.

[0025] Specifically, when installing the mounting frame 3, place the mounting frame 3 on the base frame 2, and adjust the position of the mounting frame 3, then screw the fastening screws 8 in sequence, and firmly fix the mounting frame 3 on the base frame 2 through the mounting ears 7. At this time, the fixing part moves to the working position, and the mounting frame 3 can be fixed with the fastening screws 8 through the setting of the locking part. At this time, even if the fastening screws 8 are removed, the installation effect of the mounting frame 3 will not be affected, and the possibility of the water meter body 1 being stolen is reduced. When the water meter needs to be replaced or repaired, the disconnection part is toggled and the fastening screws 8 are removed, and the mounting frame 3 can be removed, and the water meter can be replaced or repaired.

[0026] The above, such as Figure 5 As shown, the fixed part includes a mounting plate 9, an inclined frame 10 and a first connecting plate 11. Two mounting plates 9 are symmetrically and fixedly installed on both sides of the inside of the mounting frame 3, and two mounting plates 9 are symmetrically and fixedly installed on both sides of the upper part of the base frame 2. The four mounting plates 9 correspond one to one with the four inclined frames 10, and the first connecting plate 11 is fixedly installed on the four mounting plates 9.

[0027] Specifically, when the mounting frame 3 moves to the mounting position, the mounting frame 3 drives the mounting plate 9 to move to the position of the tilting frame 10. At this time, the first connecting plate 11 is just in the opening position of the tilting frame 10. At this time, the position of the first connecting plate 11 is fixed by the second connecting plate 13, and the position of the mounting frame 3 can be fixed by the mounting plate 9.

[0028] The above, such as Figure 6 , Figure 7 As shown, the locking portion includes a sliding plate 12, a second connecting plate 13 and a first spring 14. The sliding plates 12 are slidably installed inside the four tilting frames 10. The second connecting plates 13 are fixedly installed on the four sliding plates 12. The second connecting plates 13 are adapted to the first connecting plates 11. The first springs 14 are fixedly installed on the four tilting frames 10. The four first springs 14 are fixedly connected to the four sliding plates 12 respectively.

[0029] Specifically, in the process of the first connecting plate 11 moving to the connecting position, the disconnecting portion is in the connecting position, and the first spring 14 is in a compressed state. At this time, the first connecting plate 11 and the second connecting plate 13 are not in contact. After the first connecting plate 11 moves to the connecting position, the disconnecting portion is removed. Through the setting of the first spring 14, the first spring 14 pushes the sliding plate 12 to move, and the sliding plate 12 drives the second connecting plate 13 to move, until the second connecting plate 13 is moved to the position of the first connecting plate 11, at which time the first connecting plate 11 and the second connecting plate 13 are in contact, thereby fixing the position of the first connecting plate 11.

[0030] The above, such as Figure 7 , Figure 8 As shown, the disconnecting portion includes a slide groove 15 and a paddle 16. A slide groove 15 is provided on the upper part of each tilting frame 10. A paddle 16 is fixedly installed on each sliding plate 12. The paddle 16 slides with the slide groove 15. It also includes a positioning groove 17, a positioning block 18, a second spring 19 and a fixed groove 20. Positioning grooves 17 are provided on both sides of each tilting frame 10. A positioning block 18 is slidably installed inside each positioning groove 17. A second spring 19 is fixedly installed inside each positioning groove 17. The second spring 19 is fixedly connected to the positioning block 18. A fixed groove 20 is provided on each sliding plate 12, and the fixed groove 20 is adapted to the positioning block 18.

[0031] Specifically, in the process of the first connecting plate 11 moving to the connecting position, the positioning block 18 is in the fixing groove 20, and the second connecting plate 13 and the first connecting plate 11 are not in contact. When the second connecting plate 13 needs to be moved to the first connecting plate 11, the paddle 16 is held and the paddle 16 is used to move the paddle 16 until the fixing groove 20 is disengaged from the positioning block 18. At this time, the second spring 19 is compressed under the action of the positioning block 18. When the mounting frame 3 needs to be removed, the positions of the first connecting plate 11 and the second connecting plate 13 need to be disconnected. At this time, the paddle 16 is held and the fixing groove 20 on the sliding plate 12 is moved to the position of the positioning groove 17. At this time, the second spring 19 releases the pressure and presses the positioning block 18 into the fixing groove 20, thereby fixing the position of the sliding plate 12.

[0032] like Fig. 9 As shown, the alarm component is installed on the base frame 2, and the alarm component is located at the lower part of the water meter body 1, and is used to sound an alarm when the water meter is detached from the mounting frame 3. The alarm component includes a casing 21, a sliding cylinder 22, a third spring 23, a first sensor 24, a contact block 25, an alarm light 26 and a top ring 27. The casing 21 is fixedly installed on the base frame 2, and the casing 21 is located at the lower part of the water meter body 1. The sliding cylinder 22 is slidably installed inside the casing 21, the third spring 23 is fixedly installed inside the casing 21, the third spring 23 is fixedly connected to the sliding cylinder 22, the first sensor 24 is fixedly installed on the casing 21, the contact block 25 is fixedly installed on the sliding cylinder 22, the contact block 25 is adapted to the first sensor 24, the alarm light 26 is fixedly installed on the base frame 2, and a top ring 27 is fixedly installed at the lower part of the top casing 4, and the top ring 27 abuts against the water meter body 1.

[0033] Specifically, after the water meter body 1 is installed, the water meter body 1 at this time presses the sliding cylinder 22, and the bottom end of the sliding cylinder 22 contacts the inner bottom wall of the casing 21. At this time, the third spring 23 is compressed, and the contact block 25 is connected to the first sensor 24. The setting of the top ring 27 can improve the stability of the water meter body 1. When the water meter body 1 is taken out, the third spring 23 releases the pressure. At this time, the contact block 25 is separated from the first sensor 24, and the first sensor 24 is actuated. A signal transmitter is provided on the first sensor 24, and a matching signal receiver is provided on the alarm light 26. When the first sensor senses that the contact block 25 is separated from the first sensor 24, it transmits a signal to the alarm light 26, and the alarm light 26 issues a warning, thereby notifying relevant personnel and reducing the possibility of the water meter being stolen.

[0034] like Figures 10 to 12As shown, the locking assembly is installed on the top shell 4, and is used to fix the position of the top shell 4 and the mounting frame 3. The locking assembly includes a locking block 28, a lock head 29, a rotating rod 30 and a positioning portion. Locking blocks 28 are fixedly installed on both sides of the lower part of the top shell 4, and two lock heads 29 are symmetrically and fixedly installed on the mounting frame 3. The lock head 29 is located at the lower part of the locking block 28. Two rotating rods 30 are symmetrically and rotatably installed inside the mounting frame 3. The rotating rod 30 is fixedly connected to the lock core part of the lock head 29. The positioning portion is installed on the rotating rod 30 to fix the position of the top shell 4 and the mounting frame 3.

[0035] Specifically, when installing the top shell 4, place the top shell 4 on the mounting frame 3. At this time, the top shell 4 moves the locking block 28 to the locking position, and then inserts the key into the lock head 29. The key is turned, and the lock core in the lock head 29 starts to rotate. As the lock core rotates, the lock core drives the rotating rod 30 to rotate. After rotating through a certain angle, the key is pulled out. At this time, the positioning part rotates to the working position. Through the setting of the positioning part, the position of the rotating rod 30 and the top shell 4 is fixed, thereby fixing the position of the top shell 4 and the mounting frame 3.

[0036] The above, such as Fig.11 , Fig.12 As shown, the positioning portion includes a locking groove 31, an elliptical protrusion 32 and an arc groove 33. The locking groove 31 is opened at the lower part of the locking block 28, and the elliptical protrusion 32 is fixedly installed on the rotating rod 30. Arc grooves 33 are opened on both sides of the locking groove 31, and the arc groove 33 is adapted to the elliptical protrusion 32.

[0037] Specifically, the rotating rod 30 drives the elliptical protrusion 32 to rotate. When the elliptical protrusion 32 enters the arc groove 33, the rotation of the rotating rod 30 can be stopped. At this time, the relative position between the elliptical protrusion 32 and the arc groove 33 remains fixed, and the position of the mounting frame 3 and the top shell 4 can be fixed.

[0038] In summary, when installing the water meter body 1, first install the base frame 2 at the working position. After placing the base frame 2 at the working position, screw the expansion screws 6 on the positioning holes 5 into the working position in sequence to fix the base frame 2, and then install the mounting frame 3. When installing the mounting frame 3, place the mounting frame 3 on the base frame 2, and adjust the position of the mounting frame 3, and then screw the fastening screws 8 in sequence to firmly fix the mounting frame 3 on the base frame 2 through the mounting ears 7. At this time, the mounting frame 3 drives the mounting plate 9 to move to the position of the tilting frame 10. At this time, the first connecting plate 11 is just at the opening position of the tilting frame 10. In the process of the first connecting plate 11 moving to the connecting position, the positioning block 18 is in the fixing groove 20, and the second connecting plate 13 and the first connecting plate 11 are not in contact. When the second connecting plate 13 needs to be moved to the first connecting plate 11, the paddle 16 is held and the paddle 16 is used to move the paddle until the fixing groove 20 is disengaged from the positioning block 18. After the first connecting plate 11 moves to the connecting position, the first spring 14 is set to push the sliding plate 12 to move, and the sliding plate 12 drives the second connecting plate 13 to move, until the second connecting plate 13 is moved to the position of the first connecting plate 11, and the first connecting plate 11 and the second connecting plate 13 are in contact, thereby fixing the first connecting plate 11. The plate 11 is positioned, and the mounting bracket 3 is fixed with the fastening screws 8. At this time, even if the fastening screws 8 are removed, the installation effect of the mounting bracket 3 will not be affected, thereby reducing the possibility of the water meter body 1 being stolen. When the water meter needs to be replaced or repaired, the mounting bracket 3 needs to be removed, and the position of the first connecting plate 11 and the second connecting plate 13 needs to be disconnected. At this time, hold the paddle 16 and move the fixing groove 20 on the sliding plate 12 to the position of the positioning groove 17. At this time, the second spring 19 releases the pressure and presses the positioning block 18 into the fixing groove 20, thereby fixing the position of the sliding plate 12. At this time, the first connecting plate 11 and the second connecting plate 13 are detached, and the fastening screws 8 are removed, and the mounting bracket 3 can be removed, and the water meter can be replaced or repaired.

[0039] After the water meter body 1 is installed, the water meter body 1 at this time presses the sliding cylinder 22, and the bottom end of the sliding cylinder 22 contacts the inner bottom wall of the casing 21. At this time, the third spring 23 is compressed, and the contact block 25 is connected to the first sensor 24. The setting of the top ring 27 can improve the stability of the water meter body 1. When the water meter body 1 is taken out, the third spring 23 releases the pressure. At this time, the contact block 25 is separated from the first sensor 24, and the first sensor 24 is actuated. A signal transmitter is provided on the first sensor 24, and a matching signal receiver is provided on the alarm light 26. When the first sensor 24 senses that the contact block 25 is separated from the first sensor 24, a signal is transmitted to the alarm light 26, and the alarm light 26 issues a warning, thereby notifying relevant personnel and reducing the possibility of the water meter being stolen.

[0040] Then install the top shell 4. When installing the top shell 4, place the top shell 4 on the mounting frame 3. At this time, the top shell 4 moves the locking block 28 to the locked position, and then insert the key into the lock head 29. Turn the key, and the lock core in the lock head 29 starts to rotate. As the lock core rotates, the lock core drives the rotating rod 30 to rotate, and the rotating rod 30 drives the elliptical protrusion 32 to rotate. When the elliptical protrusion 32 enters the arc groove 33, the rotation of the rotating rod 30 can be stopped and the key can be pulled out. At this time, the relative position between the elliptical protrusion 32 and the arc groove 33 remains fixed, which can fix the position of the mounting frame 3 and the top shell 4, thereby fixing the position of the top shell 4 and the mounting frame 3.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
