Embodiment 1

[0030] Such as Figure 1-3 As shown, a self-sealing manhole cover for underground engineering construction based on the principle of thermal evaporation includes a base 1 and a cover body 2. The lower edge of the base 1 extends inward to form a support seat, and the upper edge extends outward to form a snap seat. Specifically, the lower end of the cover body 2 is provided with an annular groove, and the support seat of the base 1 is provided with a limit ring 11 corresponding to the annular groove; the edge of the cover body 2 fits the base 1 so that the base 1 and the cover The degree of fit between body 2 is higher, and under load-bearing conditions, the two are less likely to deviate, which improves stability.

[0031] The cover body 2 is provided with: a plurality of drain holes 21, the upper end of the drain hole 21 is arranged on the upper surface of the cover body 2, the lower end of the drain hole 21 is arranged on the inner side wall of the lower end of the cover body...

Embodiment 2

[0041] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the heat conduction plate 24 includes a spherical plate 241 and an annular reflector 242, the spherical plate 241 is fixedly connected to the center of the liquid storage box 23, and the annular reflector 242 is fixedly connected to the Outside the spherical plate 241 , the upper surface of the annular reflector 242 is a concave surface with a focus on the spherical plate 241 .

[0042] In this embodiment, the annular reflector 242 focuses on the spherical panel 241 after receiving light, which can make the spherical panel 241 heat up rapidly, making the evaporating liquid easier to be heated and vaporized; The downward depression makes it easier to collect rainwater and make the evaporative liquid more likely to be liquefied when it is cold. Therefore, the sensitivity of the entire device to the weather is greatly improved, so that it has a faster response speed.

Abstract

The invention belongs to the field of underground engineering construction equipment, and particularly relates to a self-sealing well cover for underground engineering construction based on the heat evaporation principle. The self-sealing well cover comprises a base and a cover body, the lower edge of the base extends inwards to form a supporting seat, and the upper edge of the base extends outwards to form a clamping seat; the edge of the cover body is attached to the base, and the cover body is provided with a plurality of drainage holes, a mounting groove, a liquid storage box and a heat conducting plate, wherein the upper ends of the drainage holes are formed in the upper surface of the cover body, the lower ends of the drainage holes are formed in the inner side wall of the lower endof the cover body; the mounting groove is formed in the center of the upper surface of the cover body; the liquid storage box is fixedly mounted in the mounting groove, a plurality of vertically-arranged supporting strips are distributed in the liquid storage box in an arrayed mode, and the liquid storage box is filled with low-boiling-point evaporation liquid; and the heat conducting plate is fixedly connected to the upper end of the liquid storage box. The upper ends of the drainage holes can be sealed by arranging arc-shaped sealing blocks, thus the drainage holes are prevented from being blocked by small stone or mud blocks, unobstructed drainage is kept in rainy days, and it is ensured that a large amount of accumulated water is avoided on a construction site.

Description

technical field [0001] The invention belongs to the field of underground engineering construction equipment, in particular to a self-sealing manhole cover for underground engineering construction based on the principle of thermal evaporation. Background technique [0002] During the construction of underground projects, the excavated earthwork needs to be transported away in time. During the transportation process, due to the fact that mud or small stones are prone to rolling, and the road surface of the construction site is potholed, it is easy for the transport vehicle to move during the transportation process. Sprinkle mud or small stones on the ground. These small stones or mud will easily roll down to the inspection well cover with the wheels and block the drainage holes of the inspection well cover. As a result, when it rains, the inspection well cover cannot discharge rainwater in time. , It is easy to form ponding, affecting construction and transportation. In additi...
