[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 3, the present utility model provides the following technical solutions: A low-temperature anti-freeze type Internet of Things intelligent water meter, including an anti-freeze housing 1 and an Internet of Things intelligent water meter body 2. Avoidance grooves 3 are opened on both sides of the anti-freeze housing 1. The Internet of Things intelligent water meter body 2 is placed inside the anti-freeze housing 1, and both pipelines of the Internet of Things intelligent water meter body 2 penetrate through the avoidance grooves 3. A top cover 4 is also installed on the top of the anti-freeze housing 1 through bolts. Two positioning plates 5 for inserting into the inside of the avoidance grooves 3 are fixed to the bottom of the top cover 4. The bottoms of the two positioning plates 5 are in close contact with the pipelines of the Internet of Things intelligent water meter body 2. Two heating rods 18 are also fixed to the inner wall of the anti-freeze housing 1;

[0025] A perspective window 6 is also provided on the top of the top cover 4. Two symmetrically distributed L-shaped guide plates 14 are fixed to the bottom of the top cover 4. A toothed plate 7 is slidably connected to each of the two L-shaped guide plates 14. Two symmetrically distributed first gears 8 are rotatably connected to the bottom of the top cover 4. The first gears 8 are meshed with the toothed plates 7. A second gear 9 is rotatably connected to the bottom of the top cover 4 between the two toothed plates 7. The second gear 9 is meshed with the two toothed plates 7. A connecting plate 12 is also installed on the two toothed plates 7 through screws. A cleaning layer 13 is provided on the connecting plate 12. A manual turntable 10 for driving the second gear 9 to rotate is also installed on the top of the top cover 4. The cleaning layer 13 is made of sponge material; With the above solution, during actual use, when it is necessary to heat the anti-freeze housing 1, the heating rods 18 are started to release warm air flow, forming a warm barrier inside the anti-freeze housing 1, effectively resisting the invasion of the external severe cold. As the temperature gradually rises, the Internet of Things intelligent water meter body 2 can operate stably in a suitable environment, avoiding reading errors or equipment damage caused by low temperature;

[0026] However, in the face of the problem of the perspective window 6 fogging up, the user only needs to gently rotate the manual turntable 10. This simple action drives the rotation of the second gear 9, and then through the precise engagement between the gears, drives the two toothed plates 7 to slowly move along the trajectory of the L-shaped guide plates 14. During this process, the sponge of the cleaning layer 13 connected to the toothed plates 7 gently wipes the surface of the perspective window 6, removing the condensed water mist and dust one by one;

[0027] With the reciprocating movement of the cleaning layer 13, the perspective window 6 gradually restores its original clarity. The user can clearly see the reading on the display screen of the Internet of Things intelligent water meter body 2, and no longer has to worry about the observation window fogging up. This design not only improves the user experience but also reflects the attention to details and the deep understanding of user needs.

[0028] Specifically, from Figure 1 and Figure 2As shown in the figure, in this embodiment, second arc-shaped clamping plates 20 are fixedly arranged on both sides of the antifreeze housing 1 below the avoidance grooves 3, and first arc-shaped clamping plates 19 are fixedly arranged on both positioning plates 5 above the second arc-shaped clamping plates 20. During use, the two pipelines of the Internet of Things intelligent water meter body 2 can be tightly clamped, thereby increasing the stability of the Internet of Things intelligent water meter body 2 during actual use and making it not easy to shake.

[0029] Specifically, as shown by Figure 2 and Figure 3 As shown in the figure, in this embodiment, sliding grooves 15 are formed on both L-shaped guide plates 14, connecting blocks 16 are fixedly arranged at the bottoms of the two toothed plates 7 inside the sliding grooves 15, and the connecting blocks 16 have the freedom to move along the length of the sliding grooves 15. An installation plate 17 is further fixedly arranged at the bottom of the connecting block 16, and the width of the installation plate 17 is greater than the width of the sliding grooves 15. This can effectively prevent the toothed plates 7 from falling off the L-shaped guide plates 14 during the movement process, enhancing the overall stability and durability. In addition, the design of the installation plate 17 also makes the toothed plates 7 move more smoothly, reducing the noise and wear generated by friction.

[0030] Specifically, as shown by Figure 2 and Figure 3 As shown in the figure, in this embodiment, the length of the toothed plate 7 is greater than the length of the perspective window 6. This ensures that the cleaning layer 13 can fully cover and effectively clean the entire surface of the perspective window 6 without leaving dead corners. Such a design further improves the cleaning effect, enabling users to obtain a clear and unobstructed reading experience from any angle.

[0031] Specifically, as shown by Figure 3 As shown in the figure, in this embodiment, anti-slip patterns 11 are arranged on the outer wall of the manual turntable 10. This facilitates the user to firmly grasp the manual turntable 10 during rotation, preventing slipping caused by wet hands or improper force, ensuring smooth and safe operation. In addition, the design of the anti-slip patterns 11 also enhances the friction between the hand and the manual turntable 10, making the rotation action more precisely controllable and further improving the comfort and satisfaction of the user experience.

[0032] It should be noted that both the Internet of Things intelligent water meter body 2 and the heating rod 18 are commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to actual use needs. Their working principles are common knowledge well-known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated in detail herein.

[0033] The circuit connection involved in the present utility model is a common means adopted by those skilled in the art and can obtain technical inspiration through a limited number of experiments, belonging to the widely used prior art.

[0034] The components not described in detail in this article are prior art.

[0035] Working principle and usage process of the present utility model: During actual use, when it is necessary to heat the anti-freeze housing 1, start the heating rod 18 to release warm air flow, forming a warm barrier inside the anti-freeze housing 1 to effectively resist the invasion of the external severe cold. As the temperature gradually rises, the Internet of Things intelligent water meter body 2 can operate stably in a suitable environment, avoiding reading errors or equipment damage caused by low temperature;

[0036] However, in the face of the problem of the perspective window 6 fogging up, the user only needs to gently rotate the manual turntable 10. This simple action drives the rotation of the second gear 9, and then through the precise meshing between the gears, drives the two toothed plates 7 to slowly move along the track of the L-shaped guide plate 14. During this process, the sponge of the cleaning layer 13 connected to the toothed plate 7 gently wipes the surface of the perspective window 6, removing the condensed water mist and dust one by one;

[0037] With the reciprocating movement of the cleaning layer 13, the perspective window 6 gradually returns to its original clarity. The user can clearly see the readings on the display screen of the Internet of Things intelligent water meter body 2, without having to worry about the fogging of the observation window anymore. This design not only improves the user experience but also reflects the attention to details and the profound understanding of user needs.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
