[0036] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0037] Please also read Figures 1 to 5 , the metering facility for underground burial provided by the utility model is now described. The metering facility for underground burial includes a first water supply pipe 10, a second water supply pipe 20 and a metering pipe 30 connected between the first water supply pipe 10 and the second water supply pipe 20, the metering pipe 30 is provided with a water meter 31 and a signal transmitter 32, the signal transmitter 32 is electrically connected to the water meter 31, and the metering facility for underground burial also includes a protective shell 40, an antenna 50 and a sleeve 60, the protective shell 40 includes a first shell 41 and a second shell 42 that are detachably connected, the outer periphery of the first shell 41 is provided with an air hole 43 and a wire hole 44, the second shell 42 and the first shell 41 are enclosed to form a columnar structure for wrapping the water meter 31 and the signal transmitter 32, the air hole 43 is used to inflate the protective shell 40; the antenna 50 passes through the wire hole 44 to connect with the signal transmitter 32, and the antenna 50 has a transmitting end for being placed on the ground; the sleeve 60 is arranged around the transmitting end and is used to be fixed on the ground.

[0038] It should be noted that an air pumping nozzle is provided on the air pumping hole 43, and a sealing cover is screwed on the air pumping nozzle, which has the same principle as the air pumping hole 43 on the tire. When the sealing cover is opened, the air pumping hole 43 will not automatically release air.

[0039] Optionally, the sleeve 60 set on the ground may be a cement sleeve 60 or a plastic sleeve 60 .

[0040] Compared with the prior art, the metering facility provided in this embodiment for underground burial is, after the first water supply pipe 10, the second water supply pipe 20 and the metering pipe 30 are assembled before construction, a protective shell 40 is installed on the periphery, and nitrogen is filled into the protective shell 40 through the air holes 43, so that the pressure in the protective shell 40 is greater than the atmospheric pressure, and then buried underground, wherein the transmitting end of the antenna 50 extends out of the ground, and a sleeve 60 is installed on the periphery of the transmitting end, the sleeve 60 can protect the antenna 50, so that when observing the indication of the water meter 31, the value of the water meter 31 can be directly observed on the display screen through the computer connected to the signal transmitter 32. The metering facilities used for underground installation in the utility model can be directly buried in the ground. When used in farmland, it will not occupy the cultivated area on the ground. When used in urban construction, there is no need to set a manhole cover on the ground. In addition, the protective shell 40 is used to protect the periphery of the water meter 31 and the signal transmitter 32, so that the water meter 31 can be prevented from being crushed when the ground is subjected to a large impact force. Since nitrogen is filled in the protective shell 40 and the pressure in the protective shell 40 is greater than the external atmospheric pressure, external moisture will not enter the protective shell 40, thereby preventing the water meter 31 from being damaged by moisture and extending the service life.

[0041] In some embodiments, an improved embodiment of the protective shell 40 can be as follows: Figure 4 See the structure shown. Figure 4 A butt flange assembly 70 is provided between the first water supply pipe 10 and the metering pipe 30, and between the second water supply pipe 20 and the metering pipe 30, and both sets of butt flange assemblies 70 are located in the protective shell 40. The two sets of butt flange assemblies 70 are located in the protective shell 40, and can be limited in the axial direction of the protective shell 40 inside the protective shell 40 to prevent the protective shell 40 from shifting when buried, thereby ensuring the protection effect of the water meter 31.

[0042] In a specific implementation, since the metering tube 30 is located inside the protective shell 40 and parts of the first water supply pipe 10 and the second water supply pipe 20 are located outside the protective shell 40, in order to prevent the first water supply pipe 10 and the second water supply pipe 20 from rusting, the first water supply pipe 10 and the second water supply pipe 20 can be made of plastic products and their structural strength must be ensured, while the metering tube 30 can be made of a metal tube.

[0043] In some embodiments, an improved embodiment of the protective shell 40 can be as follows: Figure 1 to Figure 2 , Figures 4 to 5 See the structure shown. Figure 1 to Figure 2 , Figures 4 to 5The outer periphery of the protective shell 40 is provided with an annular reinforcing rib 45, the axial direction of the reinforcing rib 45 coincides with the axial direction of the metering tube 30, and a plurality of reinforcing ribs 45 are distributed at intervals along the axial direction of the metering tube 30. The reinforcing ribs 45 on the outer periphery of the protective shell 40 can enhance its structural strength, and thus when a farming machine passes by the bottom surface directly above, it can resist the pressure applied by the top, and will not be deformed or damaged, and the protection of the water meter 31 is more reliable.

[0044] In some embodiments, an improved embodiment of the protective shell 40 can be adopted as follows Figures 2 to 3 See the structure shown. Figures 2 to 3 The first shell 41 has a sealing groove 46 on its butt joint surface, and the second shell 42 has a sealing protrusion 47 that matches the sealing groove 46 on its butt joint surface. The protective shell 40 also includes a sealing ring 48 located in the sealing groove 46. After the sealing ring 48 is installed in the sealing groove 46, the first shell 41 and the second shell 42 are connected, and the sealing protrusion 47 extends into the sealing groove 46 to compress the sealing ring 48, thereby improving the installation stability of the sealing ring 48 and the sealing performance of the protective shell 40, thereby preventing the leakage of nitrogen in the protective shell 40 from affecting the protection effect of the water meter 31.

[0045] In some embodiments, an improved embodiment of the protective shell 40 can be as follows: Figures 1 to 5 See the structure shown. Figures 1 to 5 The outer edge of the joint of the first shell 41 and the second shell 42 is provided with an outward flange 49, the sealing groove 46 is located at the flange 49 of the first shell 41, and the sealing protrusion 47 is located at the flange 49 of the second shell 42. That is, a circle of flange 49 is provided on the outer edge of the joint of the first shell 41 and the second shell 42, and a circle of flange 49 is provided on the outer edge of the joint of the second shell 42 and the first shell 41. If the flange 49 is not provided, the thickness of the protective shell 40 needs to be increased in order to provide the sealing groove 46 and the sealing protrusion 47. After the flange 49 is provided, the thickness of the protective shell 40 can be reduced, thereby reducing the cost. In addition, after the flange 49 is provided, the joint area between the first shell 41 and the second shell 42 is increased, and the sealing effect is better after installation.

[0046] Specifically, see Figure 5, the flanges 49 on the first shell 41 and the second shell 42 are arranged along their outer contours, the two flanges 49 located at the two axial ends of the protective shell 40 are plane + arc surface (the arc surface is used to fit the water pipe), and the other two flanges 49 are located on both sides, and the flanges 49 on both sides are planes (one is concave and the other is convex). Since the axial length of the protective shell 40 is long and the number of bolts 90 installed is large, a narrow flange 49 can be set to ensure the connection strength, while the flanges 49 at both ends need to ensure the sealing between the first water supply pipe 10 and the second water supply pipe 20, that is, the width of the flanges 49 at both ends of the first shell 41 and the second shell 42 is greater than the width of the flanges 49 on both sides of the first shell 41 and the second shell 42, and the width of the flanges 49 at both ends is equal, and the width of the flanges 49 on both sides is also equal, which can further reduce the cost while ensuring the connection strength around the protective shell 40.

[0047] In some embodiments, an improved embodiment of the protective shell 40 can be as follows: Figures 1 to 5 See the structure shown. Figures 1 to 5 The flange 49 at one end of the first shell 41 and the second shell 42 has a first arc segment 410 that fits the outer periphery of the first water supply pipe 10, and the flange 49 at the other end of the first shell 41 and the second shell 42 has a second arc segment 411 that fits the outer periphery of the second water supply pipe 20. The first arc segment 410 and the second arc segment 411 are both provided with a reinforcing strip 412 at the outer periphery of one end away from the protective shell 40. The reinforcing strip 412 here can be combined with the reinforcing rib 45 mentioned above to increase the structural strength of the protective shell 40.

[0048] Furthermore, a sealing ring 48 may be provided between the first arc segment 410 and the first water supply pipe 10 , and between the second arc segment 411 and the second water supply pipe 20 .

[0049] The sealing ring 48 here and the sealing ring 48 in the sealing groove 46 mentioned above can both be rubber rings, and the type of the rubber ring can be full foaming, semi-foaming or non-foaming.

[0050] In some embodiments, a specific implementation of the protective shell 40 may adopt the following structure. The protective shell 40 is made of photosensitive resin and has an anti-corrosion coating on the outer surface. The protective shell 40 may be manufactured using 3D printing technology, which is convenient for production, and its material combined with the anti-corrosion coating on the outer periphery may extend the service life and avoid frequent replacement.

[0051] Optionally, the anti-corrosion coating is an anti-corrosion paint.

[0052] In some embodiments, a specific assembly method of the protective shell 40 can be as follows: Figure 5 See the structure shown. Figure 5The protective shell 40 further includes bolts 90 and nuts connected between the first shell 41 and the second shell 42, and the diameter of the bolts 90 at both ends of the protective shell 40 is greater than the diameter of the bolts 90 at both sides of the protective shell 40. The bolts 90 and nuts facilitate connection, and as mentioned above, the width of the flanges 49 at both sides is less than the width of the flanges 49 at both ends, so the diameter of the bolts 90 also decreases as the width of the flanges 49 decreases.

[0053] In some embodiments, an improved embodiment of the protective shell 40 can be as follows: Figure 4 See the structure shown. Figure 4 A desiccant 80 is also placed in the protective shell 40. Nitrogen needs to be introduced into the protective shell 40 and the pressure must be greater than the external pressure. By further arranging the desiccant 80, double protection is achieved.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
