[0027] It can be understood that, with reference to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the valve well sealing device of the present application comprises a well seat 100 and a well lid 200, the well seat 100 is provided with a through hole 110, the well seat 100 is provided with a mounting groove 120, the mounting groove 120 is arranged around the through hole 110, recesses 121 are arranged on both sides of the mounting groove 120, and the recesses 121 are arranged around the mounting groove 120; the lower part of the well lid 200 is fixedly connected with a sealing strip 210, the sealing strip 210 is arranged around the well lid 200, convex strips 211 are arranged on both sides of the sealing strip 210, the convex strips 211 are arranged around the sealing strip 210, the sealing strip 210 is inserted and mounted in the mounting groove 120, so that the well lid 200 blocks the through hole 110, and the convex strips 211 are located in the recesses 121, and the convex strips 211 and the recesses 121 are one-to-one corresponding.

[0028] The well seat 100 is fixed on the ground and is provided with a through hole 110, through which the components in the valve well can be easily maintained. The well seat 100 is provided with a mounting groove 120, and grooves 121 are provided on both sides of the mounting groove 120. The well cover 200 is buckled on the well seat 100 so that the sealing strip 210 can extend into the mounting groove 120, and the protrusion 211 can be snapped into the groove 121 to increase the contact area between the sealing strip 210 and the mounting groove 120, so that the well cover 200 can block the through hole 110, prevent water from entering the valve well, and improve the sealing performance of the valve well. By providing protrusions 211 on both sides of the sealing strip 210, water can be blocked from flowing along the side walls of the sealing strip 210, thereby preventing water from entering the valve well and improving reliability.

[0029] It should be noted that the width of the sealing strip 210 is greater than or equal to the width of the mounting groove 120, so that both sides of the sealing strip 210 can abut against the two side walls of the mounting groove 120, thereby enabling the sealing strip 210 and the mounting groove 120 to be tightly connected, preventing water from seeping into the gap between the sealing strip 210 and the mounting groove 120, and improving the sealing performance of the valve well sealing device.

[0030] Among them, the sealing strip 210 and the convex strip 211 can be made of silicone or rubber, so that when the manhole cover 200 is buckled on the manhole seat 100, the two side walls of the installation groove 120 can squeeze the sealing strip 210 and the convex strip 211, so that the sealing strip 210 can be accommodated in the installation groove 120, and the convex strip 211 can be accommodated in the groove 121, which facilitates the installation of the manhole cover 200 on the manhole seat 100 and improves the installation convenience of the valve well sealing device.

[0031] It is understandable that, referring to Figure 2 The shape of the ridge 211 matches the shape of the groove 121 so that the ridge 211 can fit the side wall of the groove 121, thereby making the ridge 211 and the groove 121 tightly connected, reducing the possibility of water infiltration from between the ridge 211 and the groove 121 and improving the sealing performance.

[0032] Among them, the cross-sectional shapes of the protrusion 211 and the groove 121 can both be semicircular to increase the contact area between the protrusion 211 and the groove 121, and to facilitate the protrusion 211 to squeeze into the installation groove 120, reduce the impact between the protrusion 211 and the side wall of the installation groove 120, reduce the possibility of the protrusion 211 breaking, and improve reliability.

[0033] It is understandable that, referring to Figure 1 and Figure 2The sealing strip 210 comprises a supporting part 212 and a guiding part 213, the supporting part 212 and the guiding part 213 are arranged along the axial direction of the well lid 200, the convex strip 211 is fixedly connected to the supporting part 212, and along the axial section of the well lid 200, the width of the guiding part 213 gradually decreases in the direction away from the supporting part 212. The supporting part 212 is fixedly connected to the well lid 200, the guiding part 213 is fixedly connected to the supporting part 212, the supporting part 212 and the guiding part 213 are arranged along the axial direction of the well lid 200, and the convex strip 211 is fixedly connected to the supporting part 212, so that the convex strip 211 can protrude from both sides of the sealing strip 210, the convex strip 211 can block the water flow along the supporting part 212, the sealing property of the sealing strip 210 is improved, the possibility of water entering the valve well is reduced, and the reliability is improved.

[0034] In addition, when the sealing strip 210 is inserted into the installation groove 120, the guiding part 213 can abut against the end of the installation groove 120, and by gradually reducing the width of the guiding part 213 in the direction away from the supporting part 212, the guiding part 213 can guide the movement direction of the well lid 200, so that the well lid 200 can be smoothly buckled on the well seat 100, and the installation convenience of the well seat 100 and the well lid 200 is improved.

[0035] Specifically, referring to Figure 1 and Figure 2 , along the axial section of the well lid 200, the shape of the guiding part 213 is arc-shaped. By setting the shape of the guiding part 213 as arc-shaped along the axial section of the well lid 200, when the guiding part 213 abuts against the end of the installation groove 120, the guiding part 213 can guide the sealing strip 210 to slide into the installation groove 120, and the installation convenience of the well lid 200 is improved.

[0036] In addition, by setting the shape of the guiding part 213 as arc-shaped, when the guiding part 213 slides into the installation groove 120 from the end of the installation groove 120, the side wall of the installation groove 120 can synchronously extrude the guiding part 213, so that the guiding part 213 can uniformly deform, the guiding part 213 can be conveniently extruded into the installation groove 120, and the possibility of wear and failure of the sealing strip 210 is reduced.

[0037] It can be understood that, referring to Figure 1 and Figure 2 , the installation groove 120 and the sealing strip 210 are filled with sealing glue 130. By filling the sealing glue 130 between the installation groove 120 and the sealing strip 210, the gap between the installation groove 120 and the sealing strip 210 is reduced, the installation groove 120 and the sealing strip 210 are closely connected, water flow is prevented from seeping from the gap between the installation groove 120 and the sealing strip 210, and the sealing property is improved.

[0038] In addition, the well seat 100 and the well cover 200 are prone to expansion or contraction when the temperature changes, the sealant 130 is elastic, so that the sealant 130 can absorb the size change of the well seat 100 and the well cover 200, so that the sealing between the installation groove 120 and the sealing strip 210 is maintained, and the valve well sealing device is mainly installed outdoors, so that the well seat 100 and the well seat 100 are prone to vibration under external force. The sealant 130 can absorb and buffer the vibration of the well seat 100 and the well cover 200, improve the connection stability of the well seat 100 and the well cover 200, avoid the separation of the well seat 100 and the well cover 200, and improve the reliability of the valve well sealing device.

[0039] It can be understood that, with reference to Figure 2 and Figure 4 , the well seat 100 is provided with a water guide block 140, and the water guide block 140 is arranged around the well seat 100, and the height of the water guide block 140 gradually decreases along the radial direction of the well seat 100. The water guide block 140 is arranged around the well seat 100, and the height of the water guide block 140 gradually decreases along the radial direction of the well seat 100, so that the water guide block 140 can guide the water flow to flow away from the well seat 100, thereby avoiding the accumulation of water flow on the well seat 100 and the well cover 200, and further reducing the possibility of water flow seeping between the well seat 100 and the well cover 200, and improving the reliability of the valve well sealing device.

[0040] It can be understood that, with reference to Figure 2 and Figure 4 , the lower end of the well seat 100 is fixedly connected with a water collecting groove 150, the water collecting groove 150 protrudes inward along the radial direction of the through hole 110, and the side wall of the water collecting groove 150 is flush with the side wall of the through hole 110. The water collecting groove 150 is fixedly connected to the lower end of the well seat 100, the water collecting groove 150 protrudes inward along the radial direction of the through hole 110, and the side wall of the water collecting groove 150 is flush with the side wall of the through hole 110. By setting the side wall of the water collecting groove 150 flush with the side wall of the through hole 110, the water collecting groove 150 can collect water flow, and slow down the direct impact of water flow on the devices in the valve well.

[0041] It should be noted that when water flows from the gap between the well seat 100 and the well cover 200 into the valve well, the water collecting groove 150 can collect the inflowing water flow, thereby delaying the water inflow of the devices in the valve well, preventing the direct flushing of the devices in the valve well by the inflowing water flow, and improving the reliability of the valve well sealing device.

[0042] In addition, the well seat 100 and the well cover 200 cooperate to isolate the outside of the valve well and the inside of the valve well, so that the water vapor in the valve well is easily condensed on the well cover 200, which is easy to cause water droplets to fall on the devices in the well, affecting the operation of the devices. By setting the water collecting groove 150, the water droplets falling from the well cover 200 can be collected, and the possibility of water inflow of the devices can be reduced.

[0043] It can be understood that, with reference to Figure 1 and Figure 3 , the upper end of the well lid 200 is provided with a pull ring 220, and the pull ring 220 is rotationally connected with the well lid 200. The pull ring 220 is rotationally connected with the well lid 200, and by arranging the pull ring 220, the force applied to the well lid 200 can be facilitated, the well seat 100 and the well lid 200 can be separated, the use convenience of the valve well sealing device is improved, and the use experience is improved.

[0044] It should be noted that the crowbar can pass through the pull ring 220, the well lid 200 can be conveniently removed from the well seat 100, and the pull ring 220 is rotationally connected with the well lid 200, which can adapt to the position of the crowbar, improve the stress of the pull ring 220, reduce the possibility of the pull ring 220 being broken, and improve the reliability.

[0045] Specifically, with reference to Figure 1 and Figure 3 , the upper end of the well lid 200 is provided with an avoiding groove 230, the depth of the avoiding groove 230 is greater than or equal to the thickness of the pull ring 220, and the pull ring 220 can be accommodated in the avoiding groove 230. By arranging the avoiding groove 230 at the upper end of the well lid 200, the pull ring 220 can be accommodated in the avoiding groove 230, so that the pull ring 220 can be prevented from being affected by external force, and the service life of the pull ring 220 is prolonged.

[0046] It should be noted that since the well lid 200 is located in an outdoor environment, the depth of the avoiding groove 230 is greater than the thickness of the pull ring 220, so that the pull ring 220 can be accommodated in the avoiding groove 230, so that the pull ring 220 can be prevented from being stepped on or crushed by vehicles, the pull ring 220 can be stably accommodated in the avoiding groove 230, the service life of the pull ring 220 is prolonged, and the reliability of the valve well sealing device is improved.
