DETAILED DESCRIPTION
[0019] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0020] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.
[0021] like Figures 1-3 As shown, an anti-freezing structure for a power communication hand well includes a well body 1, a well cover 2, and a water inlet 6. The bottom of the well body 1 has an upward-facing protrusion 3, which is higher in the middle and lower at the edges. The edge of the protrusion 3 extends to the side wall of the well body 1. The side wall of the well body 1 has multiple drainage holes 4, arranged around the circumference of the side wall. In some cases, for uniformity, the drainage holes 4 can be evenly spaced, with the lowest edge of each drainage hole 4 coinciding with the edge of the protrusion 3. This arrangement of drainage holes 4 reduces water residue in the well body 1 once water enters, allowing the water to drain directly from the drainage holes 4. The well cover 2 is sealed to the top of the well body 1. The well cover 2, in conjunction with the drainage holes 4, reduces or even prevents water from entering the well body 1 and from draining through the drainage holes 4, thus reducing the likelihood of freezing. In addition, in order to promptly drain the water from the drain hole 4 and prevent it from reaching the outer wall of the well body 1 and causing freezing, a water receiving trough 6 is provided on the outer wall of the well body 1. The water receiving trough 6 is arranged around the side wall of the well body 1, and its height is lower than that of the drain hole 4. At the same time, a drain outlet 5 is provided on the water receiving trough 6. Water can be directed to a place further away from the well body 1 or to other locations by connecting a drain pipe to the drain outlet 5. Of course, this requires the height of the drain pipe to be lower than the height of the drain outlet 5, so that the water can be discharged by its own gravity. Alternatively, the drain pipe can be placed at a higher position, and a small water pump can be connected to the drain pipe to pump out the water.
[0022] Furthermore, in order to facilitate the drainage of water in the water receiving tank 6 and reduce water residue in the water receiving tank 6, the plane on which the water receiving tank 6 is located is an inclined plane, and the drain outlet 5 is set at the lowest position of the inclination of the water receiving tank 6. In this way, the water in the water receiving tank 6 flows towards the drain outlet 5, which facilitates the drainage.
[0023] Further, the sealing mode between the well lid 2 and the well body 1 is that a clamping groove 9 is arranged on the lower surface of the well lid 2 along a circumference thereof, and a sealing ring 10 is arranged in the clamping groove 9. Here, the sealing ring 10 is arranged in the clamping groove 9, which means that the sealing ring 10 is arranged on the bottom surface and the side surface of the clamping groove 9. The side surface includes an inner side surface and an outer side surface, and the sealing ring 10 is arranged on the inner side surface and the outer side surface to seal. The well lid 2 is clamped into the clamping groove 9, and a waterproof space is formed between the clamping groove 9 and the outer edge of the well lid 2. The well lid 2 is waterproofed not only by the waterproof space but also by the sealing ring 10 arranged in the clamping groove 9. The waterproof effect is improved by the two waterproof structures.
[0024] Further, the connection mode between the well body 1 and the well lid 2 is that a plurality of first threaded holes 14 are arranged on the upper surface of the well body 1 along a circumference thereof, a plurality of second threaded holes 13 are arranged in the clamping groove 9 along a circumference of the well lid 2, the plurality of first threaded holes 14 are aligned with the plurality of second threaded holes 13 and are threadedly connected with a threaded connecting piece 11. The threaded connecting piece 11 can be a screw or a bolt. The connecting position of the threaded connecting piece 11 is arranged at the bottom surface of the clamping groove 9 to ensure the sealing performance. After the threaded connection, the side surface of the clamping groove 9 can ensure the sealing performance.
[0025] Further, in order to avoid water stagnation on the well lid 2 and to timely guide the water on the well lid 2 out, a plurality of flow guide grooves 15 are arranged on the upper surface of the well lid 2. The plurality of flow guide grooves 15 are uniformly and spacedly arranged along the circumference of the well lid, and the plurality of flow guide grooves 15 are communicated at one end thereof.
[0026] Further, in order to reduce heat conduction, the well body 1 and the cover body are made of an organic composite material. The organic composite material includes organic resin, glass fiber and carbon fiber material, and is made by using an existing forming process.
[0027] Further, the inlet and outlet of the antifreeze are achieved by arranging an inlet and an outlet on the well body 1. Specifically, the inlet is arranged at the upper end of the well body 1 close to the cavity 12, and a first sealing head 8 is arranged at the inlet. The first sealing head 8 can be screwed on the well body 1 by using an existing thread, and the sealing performance is achieved by arranging a sealing ring, a sealing gasket or the like at the connecting position. An outlet is arranged at the lower end close to the cavity 12, and a second sealing head 7 is arranged at the outlet. The structure of the second sealing head 7 is the same as that of the first sealing head 8, and the structure of the second sealing head 7 is not described in detail. The antifreeze is poured into the cavity 12 by inserting a pipeline into the inlet. When the antifreeze needs to be replaced, the antifreeze is pumped out through the outlet or flows out by gravity.
[0028] The specific embodiments described above cannot be used as a limitation to the protection scope of the present application. Any alternative improvement or change made by the person skilled in the art to the embodiments of the present application falls within the protection scope of the present application.
