Description

Technical Field

[0001] This utility model belongs to the field of water meter technology, specifically, it relates to a cat1 IoT water meter with an optimized sealing and antifreeze structure. Background Technology

[0002] The Cat1 IoT water meter is a smart water meter that uses LTE Cat1 low-power wide-area network communication technology. It can transmit data such as water consumption and equipment status in real time, and supports remote monitoring, abnormal alarms and data analysis to improve water management efficiency and help save water and reduce consumption.

[0003] Patent application CN219368838U discloses an antifreeze device for water meters. Because four nuts are threaded onto four lead screws, when the operator rotates two limiting rods 90 degrees, the two limiting rods contact the connecting plate, limiting the connection plate and making the sealing cover more secure after installation, thus improving the sealing effect. Although the device can seal the sealing cover, because the limiting seat and the limiting rods are rotatably connected via a connecting shaft, in actual use, when the water meter antifreeze component and the water meter antifreeze cover are impacted, the limiting rods will shake under the impact force. When the limiting rods shake, they will rotate. When the rotation angle of the limiting rods is large, the sealing cover cannot be fixed, easily causing it to detach, thus affecting the sealing and antifreeze effect. Utility Model Content

[0004] To address the technical problem of poor sealing and antifreeze performance of the sealing cap, this utility model provides a cat1 IoT water meter with an optimized sealing and antifreeze structure.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cat1 IoT water meter with an optimized sealing and antifreeze structure includes a water meter body; an upper insulation shell and a lower insulation shell are respectively disposed above and below the water meter body, and the water meter body is located inside the upper and lower protective shells; characterized in that:

[0007] An observation port is provided above the upper insulation shell at the position corresponding to the middle of the water meter body. A sealing port is provided above the upper insulation shell at the position corresponding to the observation port. A sealing cover is provided inside the sealing port. A storage groove is provided below the sealing cover at the position corresponding to the sealing port. A pressure plate is slidably connected inside the storage groove. A first spring is connected between the pressure plate and the sealing cover. A second insulation ring is connected to the lower surface of the pressure plate.

[0008] The upper surface of the upper insulation shell is connected to the corresponding position of the sealing cover, and a symmetrically arranged outer shell is connected to it. A wedge block is slidably connected inside the outer shell. The lower surface of the wedge block is in contact with the upper surface of the sealing cover. A second spring is connected between the wedge block and the outer shell, and a second lever is connected to the upper surface of the wedge block.

[0009] Preferably, both the inner walls of the upper and lower insulation shells are connected to insulation layers, and a first insulation ring is connected to the lower surface of the sealing cover at the position corresponding to the storage groove.

[0010] Preferably, the water meter body is connected with symmetrically arranged positioning blocks at the positions corresponding to the upper and lower insulation shells. The positioning blocks are rectangular, and positioning grooves are opened at the positions of the positioning blocks at the positions of the upper and lower insulation shells. The positioning blocks are engaged in the positioning grooves.

[0011] Preferably, the upper insulation shell has symmetrically arranged semi-circular first fixing plates on both sides, and the lower insulation shell has symmetrically arranged semi-circular second fixing plates on both sides corresponding to the positions of the first fixing plates. The first fixing plates and the second fixing plates each have a fixing groove in the middle, and a semi-circular insert is slidably connected in the fixing groove.

[0012] Preferably, the first fixing plate and the second fixing plate are arranged in a circle, and the corresponding two inserts are arranged in a centrally symmetrical manner.

[0013] Preferably, a slider is connected to the outer arc position of the two corresponding inserts at their ends that are far apart from each other. A groove is opened on the first fixed plate and the second fixed plate at the position corresponding to the slider. The slider is slidably connected in the groove. A first lever is connected to the end of the slider that is far away from the insert.

[0014] The beneficial effects of this utility model are:

[0015] Align the sealing cap with the sealing opening and insert it. During insertion, the sealing cap will contact the wedge-shaped block and compress it. The wedge-shaped block, under pressure, will slide into the outer shell. As it slides, it will compress the second spring. The second spring, after being compressed, will contract and store its restoring force. Continuing to insert the sealing cap, the pressure block will first contact the sealing opening. After contacting the sealing opening, the pressure block will stop descending. The sealing cap's continued descent will send the pressure block into the receiving slot. Once inside the receiving slot, the pressure block will compress the first spring. The first spring, after being compressed, will contract and store its restoring force. This restoring force acts on the pressure block, which then transfers it to the second insulation ring, ensuring a tight seal between the second insulation ring and the sealing opening, thereby enhancing the seal and insulation. Effects: When the sealing cover is fully inserted into the sealing opening, it no longer compresses the wedge block. After the wedge block loses its compression, it resets under the action of the second spring's restoring force, placing the wedge block above the sealing cover. Under the action of the first spring's restoring force, the sealing cover adheres tightly to the wedge block, thus strengthening the sealing cover's fixation effect, preventing it from detaching from the sealing opening, and ensuring a tight seal. When it is necessary to observe the water meter's reading, by simultaneously moving the two second levers, the wedge block enters the outer casing. Once inside, the sealing cover loses its obstruction, and under the action of the first spring's restoring force, it moves out of the sealing opening. The sealing cover can then be removed for inspection, facilitating the removal of the sealing cover and improving efficiency.

[0016] Place the upper and lower insulation layers on the outside of the water meter body, align the positioning grooves of the upper and lower insulation shells with the positioning blocks, and insert the positioning blocks into the positioning grooves to initially position the upper and lower insulation shells. After the positioning blocks are inserted into the positioning grooves, move the four sets of corresponding pairs of levers one by one. The levers move the inserts, causing the inserts in the first fixing plate to insert into the second fixing plate, and the inserts in the second fixing plate to insert into the first fixing plate. After insertion, the upper and lower insulation shells are fixed together. When maintenance is required, move the four sets of corresponding pairs of levers one by one to return the inserts corresponding to the first and second fixing plates to their respective positions, thus disconnecting the upper and lower insulation shells. The upper and lower insulation shells can then be removed from the outside of the water meter body for maintenance. This method is convenient for installing, fixing, and removing the upper and lower insulation shells, improving efficiency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 6 As shown, a cat1 IoT water meter with an optimized sealing and antifreeze structure includes a water meter body 1. An upper insulation shell 11 and a lower insulation shell 12 are respectively provided above and below the water meter body 1. The water meter body 1 is located inside the upper and lower protective shells. The upper insulation shell 11 and the lower insulation shell 12 are used to protect the water meter body 1.

[0032] The water meter body 1 is connected to symmetrically arranged positioning blocks 13 at the two ends of the upper insulation shell 11 and the lower insulation shell 12. The positioning blocks 13 are rectangular and are used to limit the installation position of the upper insulation shell 11 and the lower insulation shell 12.

[0033] Positioning grooves 14 are provided at both ends of the upper insulation shell 11 and the lower insulation shell 12 corresponding to the positions of the positioning blocks 13. The positioning blocks 13 are engaged in the positioning grooves 14. Through the cooperation of the positioning blocks 13 and the positioning grooves 14, the installation positions of the upper insulation shell 11 and the lower insulation shell 12 can be determined.

[0034] The upper insulation shell 11 is connected to two sides of a symmetrically arranged semi-circular first fixing plate 2, and the lower insulation shell 12 is connected to two sides of a symmetrically arranged semi-circular second fixing plate 21 at the positions corresponding to the first fixing plate 2. The first fixing plate 2 and the second fixing plate 21 are used to assist in connecting the upper insulation shell 11 and the lower insulation shell 12.

[0035] The first fixing plate 2 and the second fixing plate 21 are arranged in a circle. This arrangement ensures that the insert 23 can enter the fixing groove 22.

[0036] Both the first fixing plate 2 and the second fixing plate 21 have fixing grooves 22 in the middle. Semi-circular inserts 23 are slidably connected in the fixing grooves 22. The two corresponding inserts 23 are arranged symmetrically between the center. Through the cooperation of the inserts 23 and the sliding grooves 25, the inserts 23 corresponding to the upper fixing plate enter the lower fixing plate, and the inserts 23 corresponding to the lower fixing plate enter the upper fixing plate, so that the upper insulation shell 11 and the lower insulation shell 12 can be connected together.

[0037] Two corresponding insert blocks 23 are connected to sliders 24 at their outer arc positions at their far ends. The first fixing plate 2 and the second fixing plate 21 are provided with grooves 25 at the positions corresponding to the sliders 24. The sliders 24 are slidably connected in the grooves 25. The end of the slider 24 away from the insert block 23 is connected to a first lever 26. Through the cooperation between the slider 24 and the groove 25, it is ensured that the insert block 23 can slide when the first lever 26 is moved.

[0038] The first fixing plate 2 and the second fixing plate 21 are connected to symmetrically arranged stop blocks 27 at their ends corresponding to the positions of the first lever 26. The stop blocks 27 are used to block the first lever 26 and prevent the first lever 26 from moving excessively.

[0039] In practical use, the upper insulation layer 15 and the lower insulation layer 15 are placed on the outside of the water meter body 1, and the positioning grooves 14 of the upper insulation shell 11 and the lower insulation shell 12 are aligned with the positioning block 13, so that the positioning block 13 is inserted into the positioning groove 14 to initially position the upper insulation shell 11 and the lower insulation shell 12. After the positioning block 13 is inserted into the positioning groove 14, the four sets of two corresponding paddles are moved one by one. The paddles are moved to move the insert 23, so that the insert 23 in the first fixing plate 2 is inserted into the second fixing plate 21, and the insert 23 in the second fixing plate 21 is inserted into the first fixing plate 2. After they are inserted, the upper insulation shell 11 and the lower insulation shell 12 can be fixed together.

[0040] When maintenance is required, by moving the four sets of two corresponding levers one by one, the inserts 23 corresponding to the first fixing plate 2 and the second fixing plate 21 are returned to the first fixing plate 2 and the second fixing plate 21 respectively, thereby disconnecting the upper insulation shell 11 and the lower insulation shell 12. The upper insulation shell 11 and the lower insulation shell 12 can then be removed from the outside of the water meter body 1, so that the parts that need maintenance can be repaired. The installation, fixing and removal of the upper insulation shell 11 and the lower insulation shell 12 are more convenient and can improve efficiency.

[0041] Both the upper insulation shell 11 and the lower insulation shell 12 are connected to an insulation layer 15. The insulation layer 15 is used to keep the upper insulation shell 11 and the lower insulation shell 12 warm, so as to prevent the upper body from freezing in winter.

[0042] An observation port 3 is provided above the upper insulation shell 11 at the position corresponding to the middle of the water meter body 1. The observation port 3 is used to observe the value of the water meter body 1.

[0043] A sealing opening 31 is provided above the upper insulation shell 11 at the position corresponding to the observation port 3. The sealing opening 31 is used to place the sealing cover 32.

[0044] A sealing cover 32 is provided inside the sealing port 31. The sealing port 31 and the sealing cover 32 cooperate to block the observation port 3.

[0045] A storage groove 33 is provided below the sealing cover 32 at the position corresponding to the sealing port 31. A pressure plate 34 is slidably connected in the storage groove 33. A first spring 35 is connected between the pressure plate 34 and the sealing cover 32. The first spring 35 is used to reset the pressure plate 34 and press the second heat insulation shell tightly at the sealing port 31.

[0046] A first heat-insulating ring 36 is connected to the lower surface of the sealing cover 32 at the position corresponding to the storage groove 33, and a second heat-insulating ring 37 is connected to the lower surface of the pressure plate 34. Both the first heat-insulating ring 36 and the second heat-insulating ring 37 are in contact with the sealing opening 31. Through the cooperation of the first heat-insulating ring 36 and the second heat-insulating ring 37, the sealing opening 31 can be insulated.

[0047] The upper surface of the upper insulation shell 11 is connected to the outer shell 4 symmetrically arranged at the position corresponding to the sealing cover 32. A wedge block 41 is slidably connected inside the outer shell 4. The lower surface of the wedge block 41 is in contact with the upper surface of the sealing cover 32. The wedge block 41 is used to block the sealing cover 32 and prevent the sealing cover 32 from falling out of the sealing port 31.

[0048] A second spring 42 is connected between the wedge block 41 and the outer casing 4. The second spring 42 is used to reset the wedge block 41.

[0049] A second lever 43 is connected to the upper surface of the wedge block 41. The second lever 43 is used to move the wedge block 41 so that the wedge block 41 enters the outer casing 4.

[0050] The outer casing 4 has a movable groove 44 at the position corresponding to the second lever 43. The second lever 43 is slidably connected in the movable groove 44. Through the cooperation of the movable groove 44, the second lever 43 can drive the wedge block 41 to move.

[0051] In specific use,

[0052] When the sealing cap 32 is aligned with the sealing opening 31, it is inserted. During insertion, the sealing cap 32 will contact the wedge block 41 and press the wedge block 41. The wedge block 41 will slide into the outer shell 4 under pressure. During the sliding process, the wedge block 41 will press the second spring 42. After being pressed, the second spring 42 will contract and store the restoring force. During the continued insertion of the sealing cap 32, the pressure block will first contact the sealing opening 31. After contacting the sealing opening 31, the pressure block will stop descending. The sealing cap 32 will continue to descend and send the pressure block into the storage groove 33. After entering the storage groove 33, the pressure block will press the first spring 35. After being pressed, the first spring 35 will contract and store the restoring force. The restoring force acts on the pressure block, and the pressure block will transfer the restoring force to the second insulation ring 37, so that the second insulation ring 37 is tightly attached to the sealing opening 31, thereby enhancing the sealing and heat preservation effect.

[0053] When the sealing cap 32 is fully inserted into the sealing opening 31, the sealing cap 32 no longer presses against the wedge block 41. After the wedge block 41 is no longer pressed, it will reset under the action of the restoring force of the second spring 42, so that the wedge block 41 is above the sealing cap 32. Under the action of the restoring force of the first spring 35, the sealing cap 32 will be tightly attached to the wedge block 41, thereby strengthening the fixing effect of the sealing cap 32, preventing the sealing cap 32 from detaching from the sealing opening 31, and ensuring the sealing performance.

[0054] When it is necessary to observe the value of the water meter body 1, by simultaneously moving the two second levers 43, the wedge block 41 is moved into the outer casing 4. After the wedge block 41 is moved into the outer casing 4, the sealing cover 32 is no longer obstructed. Under the action of the restoring force of the first spring 35, the sealing cover 32 will move out from the sealing port 31. The sealing cover 32 can be removed for inspection, which facilitates the removal of the sealing cover 32 and improves efficiency.
