Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0042] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0043] Specific implementation method one: Combining Figure 1The illustration shows this specific embodiment. This embodiment uses a sealed manhole cover 3 to achieve a sealed manhole opening, preventing air from entering the manhole. Simultaneously, the composite insulation board mechanism 4 provides insulation for the manhole. The specific technical solution includes a concrete manhole body 1, a manhole cover frame 2, a sealed manhole cover 3, and a composite insulation board mechanism 4. The manhole cover frame 2 is installed at the upper end of the concrete manhole body 1, enabling the sealed manhole cover 3 to be installed in a sealed manner. The sealed manhole cover 3 is sealed to the manhole cover frame 2, achieving a seal that prevents cold air from easily entering the manhole. The composite insulation board mechanism 4 is installed on the inner wall of the concrete manhole body 1. During construction, the composite insulation board mechanism 4 is laid approximately 1.5m below the sealed manhole cover 3, or as needed based on site conditions and minimum requirements. The temperature is controlled by a composite insulation board laying mechanism 4. The concrete well body 1 includes a vertical well 1-1 and a horizontal well 1-2, which are connected. The vertical well 1-1 facilitates workers to enter the well for maintenance, while the horizontal well 1-2 can be used for pipe laying or wiring, etc. The length of the horizontal well 1-2 needs to be determined according to the site construction conditions, and the length of the horizontal well 1-2 is 3-20m. A drainage chamber 1-3 is set at the bottom of the vertical well 1-1, and a filter plate 1-5 is set at the upper end of the drainage chamber 1-3. An inspection ladder 1-6 is set on the inner wall of the concrete well body 1, which allows maintenance personnel to enter the well. A drainage pipe 1-4 is connected to the bottom of the drainage chamber 1-3, which allows drainage from the vertical well 1-1 to the drainage chamber 1-3, preventing water from accumulating and freezing in the drainage chamber 1-3. Figure 2 As shown, the filter plate 1-5 has several through drainage channels 1-51, which allow water to enter the drainage chamber 1-3.

[0044] In this specific embodiment, the vertical shaft 1-1 of the concrete well body 1 is used for workers to go down into the well for maintenance, while the horizontal shaft 1-2 can realize wiring and pipe laying, etc. When maintenance is required, the sealed well cover 3 is lifted and the maintenance ladder 1-6 is used to go down into the well for maintenance. The well body is insulated by the composite insulation board mechanism 4, so that the well body is not prone to freezing and the pipes in the well are not prone to freezing and cracking. At the same time, when there is water in the vertical shaft 1-1 or the horizontal shaft 1-2, the water will enter the drainage chamber 1-3 and be discharged through the drainage pipe 1-4 to prevent water from accumulating in the vertical shaft 1-1 or the horizontal shaft 1-2 and freezing.

[0045] Specific Implementation Method Two: Combining Figure 3The following is an illustration of this specific embodiment, which is a further limitation of Specific Embodiment 1. In this specific embodiment, the manhole cover frame 2 can be cast onto the ground. The specific technical solution is as follows: A through-hole groove 2-1 is opened in the middle of the manhole cover frame 2. A manhole cover groove 2-2 is connected to the upper side of the through-hole groove 2-1. The manhole cover groove 2-2 can seal the manhole cover 3. A manhole cover sealing gasket 2-3 is installed at the bottom of the manhole cover groove 2-2. The manhole cover sealing gasket 2-3 can seal with the manhole cover 3. Several connecting threaded holes 2-4 are opened on the outer side wall of the manhole cover frame 2. A casting rod 2-5 is connected in the connecting threaded holes 2-4. The casting rod 2-5 can cast the manhole cover frame 2 and improve the strength of the manhole cover frame 2. A fall protection net 2-6 is installed at the lower inner end of the manhole cover frame 2 through a hook. The fall protection net 2-6 can improve safety and prevent people from falling into the manhole.

[0046] In this specific embodiment, during the pouring process, the manhole cover frame 2 is placed at the manhole opening, and the upper surface of the manhole cover frame 2 is adjusted to be horizontal with the ground. The pouring rod 2-5 is installed in the connecting threaded hole 2-4 of the manhole cover frame 2. After pouring, the pouring rod 2-5 can improve the strength and stability of the manhole cover frame 2. When workers need to go down into the well, the fall protection net 2-6 needs to be removed. At this time, workers can be lowered for maintenance, and the fall protection net 2-6 can prevent pedestrians or workers from falling into the well due to accidents.

[0047] Specific implementation method three: Combining Figure 4 , Figure 5 The illustration shows this specific embodiment, which is a further limitation of embodiment one or two. In this specific embodiment, the sealing manhole cover 3 achieves sealing and heat preservation, and the specific technical solution adopted is as follows: A sealing gasket 3-1 is bonded to the bottom of the sealing manhole cover 3. The sealing gasket 3-1 is an HNBR hydrogenated nitrile rubber sealing gasket. The sealing manhole cover 3 includes a cast iron cover 31, a heat insulation cotton body 32, an STP vacuum insulation board cover 33, and a pressure-resistant plate 34. A groove is opened in the inner bottom of the cast iron cover 31, and the heat insulation cotton body 32 is arranged in the groove. The heat insulation cotton body 32 can achieve heat preservation. The bottom of the heat insulation cotton body 32 is provided with the STP vacuum insulation board cover 33. The bottom of the STP vacuum insulation board cover 33 is provided with the pressure-resistant plate 34, which can improve the pressure resistance.

[0048] In this specific embodiment, the sealing well cover 3 improves the sealing performance through the sealing gasket 3-1, and improves the overall strength through the cast iron cover 31. The cast iron cover 31 improves the heat insulation performance of the cover through the heat insulation cotton body 32 and the STP vacuum insulation board cover 33, making it difficult for cold air to enter the well. At the same time, the pressure-resistant plate body 34 can improve the pressure resistance and extend the strength of the cast iron cover 31.

[0049] Specific implementation method four: Combination Figure 6 , Figure 7 , Figure 8 This embodiment illustrates a further limitation of embodiment one, two, or three. In this embodiment, the insulation performance inside the well is improved through a composite insulation board mechanism 4. The specific technical solution is as follows: The composite insulation board mechanism 4 includes a composite insulation board 4-1 and a mounting frame 4-2. The composite insulation board 4-1 is inserted into the mounting frame 4-2, enabling the installation of the composite insulation board 4-1. The mounting frame 4-2 is bolted to the inner wall of the concrete well body 1. The composite insulation board 4-1 includes a reflective aluminum foil layer 4-11, a rock wool board 4-12, a polyurethane foam insulation board 4-13, and a fiberglass board 4-14. The inner wall of the rock wool board 4-12 is provided with a reflective aluminum foil layer 4-11. A polyurethane foam insulation board 4-13 is installed on the outer wall of the rock wool board 4-12, and a fiberglass board 4-14 is installed on the outer wall of the polyurethane foam insulation board 4-13. A reflective aluminum foil layer 4-11 reduces heat radiation loss. The use of rock wool board 4-12 and polyurethane foam insulation board 4-13 can improve the insulation performance, and fiberglass board 4-14 can improve the strength. The mounting frame 4-2 is I-shaped, which forms two insertion slots. Several mounting through holes 4-21 are opened at the bottom of the mounting frame 4-2. The outer side of the mounting through holes 4-21 is connected to a countersunk hole 4-22. The mounting through holes 4-21 can be used to install the mounting frame 4-2 on the inner wall of the concrete well body 1 by bolts, while the countersunk hole 4-22 can be used to insert the bolt tail.

[0050] In this specific embodiment, the mounting frame 4-2 of the composite insulation board mechanism 4 is installed on the inner wall of the concrete well body 1. At this time, the mounting frame 4-2 is installed on the inner wall of the concrete well body 1 by bolts passing through the mounting through hole 4-21. Then, adhesive is applied to the back of the composite insulation board 4-1 to achieve bonding of the composite insulation board 4-1. At the same time, the composite insulation board 4-1 is inserted into the insertion groove formed by the mounting frame 4-2, so that the composite insulation board 4-1 is doubly fixed, making it less likely for the composite insulation board 4-1 to fall off. At the same time, the composite insulation board 4-1 can improve the insulation performance.

[0051] Specific Implementation Method Five: Combining Figure 8 , Figure 9 , Figure 10The following describes a specific embodiment, which is another scheme of embodiment four. In order to improve the thermal insulation and prevent freezing, a heat tracing cable 4-15 is installed inside the polyurethane foam insulation board 4-13. Both ends of the heat tracing cable 4-15 are connected to interfaces 4-16. The interfaces 4-16 of the heat tracing cable 4-15 are connected to the interfaces 4-16 of another heat tracing cable 4-15 through connectors. A temperature sensor and an intelligent temperature control module are fixedly installed inside the concrete well body 1. The temperature sensor is connected to the input end of the intelligent control module, and the output end of the intelligent control module is connected to the heat tracing cable 4-15. The heat tracing cable 4-15, the temperature sensor, and the intelligent temperature control module are all commercially available products, and their working principle is existing technology, which will not be described in detail here.

[0052] Meanwhile, in order to enable the connector of interface 4-16 to be wired in this specific embodiment, a wire-passing groove 4-23 is provided in the middle of the mounting frame 4-2. The wire-passing groove 4-23 can enable the connector to be passed through, which facilitates wiring and enables the connection of the upper and lower heat tracing cables 4-15.

[0053] In this specific embodiment, auxiliary temperature control is achieved through the heating cable 4-15, which can be set to automatically start when the temperature drops below 5°C. At the same time, in order to reduce energy consumption, the existing solar power supply system can be used to provide power, which can save energy.
