Description

Technical Field

[0001] The invention relates to the technical field of water meter boxes, and in particular to an antifreeze underground water meter box. Background Art

[0002] With the acceleration of urbanization, the management and protection of groundwater resources have become particularly important. As a key device connecting the underground water supply network and users, the performance of the groundwater meter box directly affects the stability and reliability of the water supply system. Especially in cold areas, the design and use of antifreeze groundwater meter boxes are particularly important.

[0003] However, traditional antifreeze underground water meter boxes have some significant problems in practical applications. These problems not only affect the service life of water meters and water pipes, but may also lead to waste of water resources. For example, traditional antifreeze underground water meter boxes usually install multiple water meters and water pipes in a closed space. When a component is damaged and causes leakage, the leaked water will not only directly damage the surrounding water meters and water pipes, but may also cause corrosion and rust of metal parts due to long-term immersion, further causing more damage. Moreover, in the early stage of leakage, due to the small amount of water, it is difficult for staff or water users to detect it in time. Once the leakage problem is not discovered and handled in time, it will lead to a large waste of water resources, increase maintenance costs and environmental burden. Summary of the invention

[0004] In view of this, the present invention provides an antifreeze underground water meter box, which can solve the problem that when water leakage occurs in the traditional antifreeze underground water meter box, it will not only damage the water meter and water pipes in the box, but may also cause corrosion and rust of metal parts due to long-term immersion, further causing more damage, and will also lead to waste of water resources, increase maintenance costs and environmental burden.

[0030] See also Figure 2 As shown, the heating mechanism includes a temperature detector 801 and a heating tube 802. The left wall of the box body 1 is provided with a temperature detector 801 for detecting the temperature; a heating tube 802 is installed at the bottom of the box cover 2, and the heating tube 802 is used to heat the inside of the box body 1.

The temperature detector 801 and the heating tube 802 are both electrically connected to the controller 12.

[0031] See also Figure 6 and Figure 7 As shown, the moving mechanism includes a waterproof motor 1301 and a screw rod 1302; the waterproof motor 1301 is symmetrically installed on the front and back of the upper right wall of the box body 1, the waterproof motor 1301 penetrates the insulation board 6 inside the box body 1, the waterproof motor 1301 is electrically connected to the battery of the power storage component 701, and the waterproof motor 1301 is electrically connected to the controller 12; the output shafts of the two waterproof motors 1301 are connected to the screw rod 1302, the left end of the screw rod 1302 penetrates the insulation board 6 inside the box body 1, and the left end of the screw rod 1302 is rotatably connected to the left wall inside the box body 1, and the movable frame 14 is threadedly connected to the two screw rods 1302.

[0032] See also Figure 6 and Figure 7 As shown, the limiting mechanism includes a rubber block 1701 and a stopper 1702; a rubber block 1701 is arranged on the right side of the bottom of the box body 1, and the rubber plate 16 on the rotating frame 15 contacts the rubber block 1701. Through the contact between the rubber plate 16 and the rubber block 1701, the rotating frame 15, the rubber plate 16 and the rubber block 1701 can block the drainage hole 101, thereby preventing the outside air from entering the box body 1 from the drainage hole 101; a stopper 1702 is connected to the left side of the bottom of the box body 1, and the stopper 1702 is located on the outside of the controller 12. The rubber block 1701 and the stopper 1702 are both used to limit the movable frame 14.

[0033] When in use, the box 1 is placed underground, and then the main pipe 3 and the branch pipe 4 are connected to the corresponding water pipes respectively, so that the water flows into the main pipe 3 and then flows out from the branch pipe 4. The water meter 5 is used to measure and record the amount of water transported through the branch pipe 4. Then, the height of the photovoltaic panel 703 is adjusted by adjusting the length of the multi-section telescopic rod 702, so that the photovoltaic panel 703 is in a position with better light. When sunlight shines on the photovoltaic panel 703, the photovoltaic panel 703 converts solar energy into electrical energy, which is stored in the battery of the power storage component 701, and is used to supply the temperature detector 801, the heating tube 802, the control valve 10, the water leakage sensing rope 11, the controller 12 and the waterproof motor 13. 01 is used, so that the temperature detector 801 can continuously detect the temperature in the box 1. When the temperature detector 801 detects that the temperature in the box 1 is lower than the preset value, the temperature detector 801 sends a signal. After receiving the signal, the controller 12 controls the heating tube 802 to heat the box 1, so that the temperature in the box 1 is increased. When the temperature detector 801 detects that the temperature in the box 1 is higher than the preset value, the temperature detector 801 sends a signal. After receiving the signal, the controller 12 controls the heating tube 802 to stop heating the box 1, so that the box 1 is within a suitable temperature range, thereby preventing the components in the box 1 from freezing in cold weather;

[0034] When the main pipe 3, the branch pipe 4 or the water meter 5 in the box body 1 leaks, the water leaked from the main pipe 3, the branch pipe 4 and the water meter 5 will be absorbed by the sponge cover 9 to prevent the leaked water from flowing onto the surrounding components. At the same time, as the water absorbed by the sponge cover 9 gradually increases, the water on the sponge cover 9 will gradually fall down to the bottom of the box body 1 to form accumulated water. When the leakage sensing rope 11 senses the water on the sponge cover 9, the leakage sensing rope 11 will send a signal. After receiving the signal, the controller 12 will control the corresponding control valve 10 according to the corresponding leakage sensing rope 11 to block the main pipe 3 or the branch pipe 4, so that the water in the main pipe 3 or the branch pipe 4 stops flowing, thereby preventing the main pipe 3, the branch pipe 4 or the water meter 5 from continuing to leak, so as to prevent the leaked water from submerging the components in the box body 1, and the controller 12 will send the leakage signal to the information center, so that the staff can know the main pipe 3, the branch pipe 4 and the water meter 5 in the box body 1 according to the information center. If there is a water leak in the pipe 4 or the water meter 5, the staff can promptly notify the maintenance personnel to carry out maintenance. At the same time, the controller 12 will control the waterproof motor 1301 to drive the screw rod 1302 to rotate, so that the screw rod 1302 drives the movable frame 14, the rotating frame 15 and the rubber plate 16 to move to the left, until the rotating frame 15 contacts the stop block 1702, so that the stop block 1702 limits the rotating frame 15. At the same time, as the rubber plate 16 moves to the left, the rubber plate 16 will separate from the rubber block 1701, so that the rotating frame 15, the rubber plate 16 and the rubber block 1701 no longer block the drainage hole 101, so that the accumulated water at the bottom of the box body 1 can be discharged from the drainage hole 101 to prevent the accumulated water from remaining at the bottom of the box body 1. At the same time, as the roller structure of the rotating frame 15 rolls to the left at the bottom of the box body 1, the rotating frame 15 can be rotated upward until it is blocked by the movable frame 14, so that the rubber plate 16 is separated from the bottom of the box body 1 (such as Figure 7As shown), when the rotating frame 15 continues to move to the left, the roller structure of the rotating frame 15 will slide at the bottom of the box body 1, and then wait for a period of time, so that a large amount of water on the sponge cover 9 will fall down to the bottom of the box body 1 to form accumulated water, and the accumulated water at the bottom of the box body 1 has enough time to be discharged from the drainage hole 101. After a period of time, the controller 12 will automatically control the heating tube 802 to heat the inside of the box body 1, so as to heat the sponge cover 9 and the water leakage sensing rope 11 in the box body 1, so that the sponge cover 9 and the water leakage sensing rope 11 are in a dry state. When the water leakage sensing rope 11 cannot sense the water on the sponge cover 9, the water leakage sensing rope 11 will send a signal. After receiving the signal, the controller 12 will control the heating tube 802 to stop heating the inside of the box body 1. At the same time, the controller 12 The waterproof motor 1301 will be controlled to drive the screw rod 1302 to reverse and reset, so that the screw rod 1302 drives the movable frame 14, the rotating frame 15 and the rubber plate 16 to move to the right and reset. At the same time, as the roller structure of the rotating frame 15 rolls to the right at the bottom of the box body 1, the rotating frame 15 can be rotated downward and reset, so that the rubber plate 16 contacts the bottom of the box body 1. Then, when the rotating frame 15 continues to move to the right, the roller structure of the rotating frame 15 will slide at the bottom of the box body 1. At the same time, the rubber plate 16 on the rotating frame 15 will push the accumulated water at the bottom of the box body 1 to the drainage hole 101, so that the accumulated water at the bottom of the box body 1 can be discharged through the drainage hole 101 until the rubber plate 16 contacts the rubber block 1701, so that the rubber block 1701 limits the rubber plate 16 (such as Figure 6 As shown, the controller 12 controls the waterproof motor 1301 to drive the screw rod 1302 to intermittently rotate forward and reverse for a period of time, so that the screw rod 1302 drives the movable frame 14, the rotating frame 15 and the rubber plate 16 to move back and forth, so that the rubber plate 16 can push all the accumulated water at the bottom of the box body 1 to the drainage hole 101, so that all the accumulated water at the bottom of the box body 1 can be discharged through the drainage hole 101. After a period of time, the controller 12 controls the waterproof motor 1301 to drive the screw rod 1302 to stop intermittently rotating forward and reverse, so that all the accumulated water at the bottom of the box body 1 can be discharged, so as to prevent the metal parts in the box body 1 from being corroded and rusted due to being soaked in clean water for a long time;

[0035] When the maintenance worker needs to repair the leaking main pipe 3, branch pipe 4 or water meter 5 in the box body 1, he pulls the box cover 2 to rotate it open, and then he can repair the leaking main pipe 3, branch pipe 4 or water meter 5 in the box body 1. After the leaking main pipe 3, branch pipe 4 or water meter 5 in the box body 1 is repaired, he pushes the box cover 2 to reverse and close it, and then controls the corresponding control valve 10 to restore the main pipe 3 or branch pipe 4 to be unblocked, so that the water in the main pipe 3 or branch pipe 4 can continue to flow.

[0036] See also Figure 6-Figure 8As shown, it also includes a wiper mechanism, which includes a connecting frame 18, a rubber strip 19 and a connecting pipe 20; the connecting frame 18 is installed on the top of the movable frame 14; the rubber strip 19 is symmetrically connected to the top of the connecting frame 18, and the rubber strip 19 is used to scrape off the residual water drops on the insulation board 6 at the bottom of the box cover 2; the left and right sides of the upper part of the connecting frame 18 are provided with a water collecting trough 1801 for collecting water drops; four connecting pipes 20 are symmetrically installed on the upper side of the connecting frame 18, of which the two connecting pipes on the left side are The top of 20 is connected to the water collecting tank 1801 on the left, and the tops of the two connecting pipes 20 on the right are connected to the water collecting tank 1801 on the right. The bottom ends of the four connecting pipes 20 are all lower than the bottom of the sponge cover 9. By setting the connecting pipes 20, the water in the water collecting tank 1801 is discharged to the bottom of the box body 1, which can prevent the water in the water collecting tank 1801 from overflowing and falling on the sponge cover 9 to cause residue; grooves 21 are provided on the left and right sides of the upper part of the insulation board 6 on the inner wall of the box body 1, and the grooves 21 are used for the connecting frame 18 to be inserted.

[0037] When the heating tube 802 heats the inside of the box body 1, some water vapor may float upward and adhere to the insulation plate 6 at the bottom of the box cover 2; then when the movable frame 14 moves to the left or right, the movable frame 14 will drive the connecting frame 18, the rubber strip 19 and the connecting pipe 20 to move to the left or right synchronously, so that the rubber strip 19 can scrape off the residual water droplets on the insulation plate 6 at the bottom of the box cover 2, so as to prevent the water droplets remaining on the insulation plate 6 at the bottom of the box cover 2 from affecting the components in the box body 1, and the water droplets scraped off by the rubber strip 19 will fall down into the water collecting tank 1801 for collection, and the clean water in the water collecting tank 1801 will be discharged to the bottom of the box body 1 through the connecting pipe 20, so that the clean water will eventually be discharged from the bottom of the box body 1 through the drainage hole 101.

[0038] See also Fig. 9 As shown, a filter frame 22 is also included; the filter frame 22 is connected to the bottom of the box body 1, and the filter frame 22 is connected to the drainage hole 101. The filter frame 22 is used to collect and disperse the water discharged from the drainage hole 101.

[0039] When the drainage hole 101 is discharging a large amount of water, since a large amount of clean water infiltrates slowly in the ground, water is easily accumulated in the drainage hole 101, thereby affecting the drainage efficiency of the drainage hole 101, and making it take a long time for the accumulated water at the bottom of the box body 1 to be drained. By setting the filter frame 22, the drainage hole 101 can first discharge the clean water into the filter frame 22 for collection, and then the filter frame 22 disperses the clean water and discharges it into the ground. In this way, the drainage of the accumulated water at the bottom of the box body 1 can be accelerated to prevent the accumulated water in the box body 1 from immersing the components for a long time; and the filter frame 22 can also prevent mud from entering the drainage hole 101, to prevent the drainage hole 101 from being blocked.

[0040] See also Fig. 9As shown, a heating ring 23 is also included; a heating ring 23 is sleeved on the main flow pipe 3, the heating ring 23 is located on the inner side of the sponge sleeve 9, the heating ring 23 is used to heat the clean water in the main flow pipe 3, the heating ring 23 is electrically connected to the controller 12, and the heating ring 23 is electrically connected to the battery of the power storage component 701, so that the power storage component 701 can provide electrical energy to the heating ring 23 for use.

[0041] By setting a heating ring 23, when the temperature detector 801 detects that the temperature inside the box 1 is lower than the preset value, the temperature detector 801 sends a signal. After receiving the signal, the controller 12 controls the heating tube 802 to heat the inside of the box 1, thereby raising the temperature inside the box 1. At the same time, the controller 12 controls the heating ring 23 to heat the clean water in the mainstream pipe 3 to prevent the clean water in the mainstream pipe 3 from being too cold and freezing after flowing into the branch pipe 4; when the temperature detector 801 detects that the temperature inside the box 1 is higher than the preset value, the temperature detector 801 sends a signal. After receiving the signal, the controller 12 controls the heating tube 802 to stop heating the inside of the box 1.
