Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation manhole covers, in particular to an underground fire hydrant thermal insulation manhole cover in severe cold areas. Background Art

[0002] Underground fire hydrants play an indispensable role in firefighting, and how to ensure that underground fire hydrants are not affected by freezing in cold areas has always been the focus of firefighting engineering research. In the past, underground fire hydrants were insulated by adding a layer of wooden insulation manhole cover or a layer of rock wool manhole cover wrapped with stainless steel sheet iron. These two methods have the following problems:

[0003] 1. The wooden insulated manhole cover is made of pure wood. Since the manhole cover is soaked in water, it is easy to cause the manhole cover to freeze and swell in severe cold weather and cannot be opened quickly;

[0004] 2. Traditional insulated manhole covers are fully opened during use. In extreme weather, cold air enters the manhole chamber and freezes the fire hydrant outlet in a short period of time, causing the fire hydrant outlet to be unable to be connected normally or the outlet cover to be closed normally after use;

[0005] 3. Stainless steel iron sheet encapsulates rock wool manhole cover. If the iron sheet is too thin, the manhole cover is easy to deform, and if the iron sheet is too thick, the manhole cover is too heavy;

[0006] 4. In extremely cold regions, fire hydrant well chambers are usually very deep, and opening them all during use poses a major safety hazard. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides an underground fire hydrant insulation manhole cover for use in severe cold areas, which is not prone to frost heave and can still ensure that the fire hydrant is not prone to freezing during use.

[0008] The utility model provides an underground fire hydrant insulation manhole cover for severely cold regions, comprising:

[0009] A manhole cover body, wherein the outer surface of the manhole cover body is coated with an anti-corrosion coating and the outer periphery is provided with a coating layer;

[0010] The opening and closing part includes a first hole and a second hole opened in sequence along the central axis of the manhole cover body, and a first installation cover and a second installation cover, the first installation cover and the second installation cover are movably connected to the first hole and the second hole respectively, and the first hole and the second hole are suitable for the passage of a fire hose.

[0011] Optionally, the first opening and the second opening are respectively arranged corresponding to the center of the water outlet of the fire hydrant;

[0012] The diameter of the first hole is 10 cm, the diameter of the second hole is 15 cm, and the center distance between the first hole and the second hole is 32.5 cm.

[0013] Optionally, the manhole cover body is made of pine wood, and the thickness of the manhole cover body is 3 cm.

[0014] Optionally, the coating layer is stainless steel sheet.

[0015] Optionally, the manhole cover body includes a first semicircular manhole cover and a second semicircular manhole cover having the same diameter.

[0016] Optionally, a first handle is provided on both the first semicircular manhole cover and the second semicircular manhole cover.

[0017] Optionally, the first mounting cover and the second mounting cover are both made of pine wood, and are both 3 cm thick. The diameter of the first mounting cover is 10 cm, and the diameter of the second mounting cover is 15 cm.

[0018] Optionally, a second handle is provided on the first mounting cover and the second mounting cover, and the connection between the second handle and the first mounting cover and the second mounting cover extends to the manhole cover body to be connected to the manhole cover body.

[0019] Compared with the prior art, the technical solution provided by the embodiment of the utility model has the following beneficial effects:

[0020] The underground fire hydrant insulated manhole cover for severely cold regions provided in the present embodiment can protect the manhole cover body by coating an anti-corrosion material on the outer surface of the manhole cover body, and arrange a coating layer around the manhole cover body to ensure that the manhole cover body is not easily deformed, and by arranging a first hole and a second hole in sequence on the central axis of the manhole cover body, and the first hole and the second hole are suitable for the passage of a fire hose, thereby avoiding the need to fully open the manhole cover body when the fire hose needs to be connected. In extreme weather, cold air enters the well chamber and freezes the water outlet of the fire hydrant in a short time, making it impossible to connect the fire hydrant normally after water is discharged, or the water outlet cover cannot be closed normally after use. When the fire hydrant is not needed, the first installation cover and the second installation cover are respectively installed in the first hole and the second hole to achieve blocking of the holes, thereby ensuring the temperature in the well chamber and preventing the water outlet of the fire hydrant from freezing.

DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1 and Figure 2 As shown, this embodiment provides an underground fire hydrant insulation manhole cover for severely cold regions, comprising a manhole cover body 1 and an opening and closing portion.

[0029] Among them, the outer surface of the manhole cover body 1 is coated with anti-corrosion paint, and a coating layer 2 is arranged on the outer periphery. The opening and closing part includes a first hole 3 and a second hole 4, and a first installation cover 5 and a second installation cover 6, which are opened in sequence along the central axis of the manhole cover body 1. The first installation cover 5 and the second installation cover 6 are movably connected to the first hole 3 and the second hole 4 respectively. The first hole 3 and the second hole 4 are suitable for the passage of fire hoses. Specifically, an anti-corrosion material is coated on the outer surface of the manhole cover body 1 to protect the manhole cover body 1, and a coating layer is arranged around it to ensure that the manhole cover body 1 is not easily deformed. The first hole 3 and the second hole 4 are arranged in sequence on the central axis of the manhole cover body 1, and the first hole 3 and the second hole 4 are suitable for the passage of the fire hose, so as to avoid the need to fully open the manhole cover body 1 when the fire hose needs to be connected. In extreme weather, cold air enters the well chamber and freezes the water outlet of the fire hydrant in a short time, making it impossible to connect the fire hydrant normally after water is discharged, or the water outlet cover cannot be closed normally after use. When the fire hydrant is not needed, the first installation cover 5 and the second installation cover 6 are respectively installed in the first hole 3 and the second hole 4 to achieve the blocking of the holes, thereby ensuring the temperature in the well chamber and preventing the water outlet of the fire hydrant from freezing.

[0030] Further, see Figure 2 As shown, the first hole 3 and the second hole 4 are respectively arranged corresponding to the center of the water outlet of the fire hydrant; the diameter of the first hole 3 is 10 cm, the diameter of the second hole 4 is 15 cm, and the center distance between the first hole 3 and the second hole 4 is 32.5 cm. Specifically, the first hole 3 and the second hole 4 are respectively arranged corresponding to the two water outlets of the underground fire hydrant, and the first hole 3 and the second hole 4 have different diameters, which can be suitable for fire hoses of different diameters to pass through, thereby improving the applicability of the thermal insulation manhole cover.

[0031] In order to reduce the weight of the manhole cover body 1, the material of the manhole cover body 1 is pine wood, and the thickness of the manhole cover body 1 is 3 cm.

[0032] Since wooden manhole covers are easily soaked in water, they may freeze and swell in severe cold weather and become unable to be opened quickly. The manhole cover provided in this embodiment is provided with a coating layer 2 on the outer periphery of the manhole cover body 1. The coating layer 2 is made of stainless steel sheet iron. The stainless steel sheet iron sheet is used for edging reinforcement to reduce the impact of the frost heave of the manhole cover body 1.

[0033] Reference Figure 1 and Figure 2 As shown, the manhole cover body 1 includes a first semicircular manhole cover 101 and a second semicircular manhole cover 102 with the same diameter. Specifically, the manhole cover body 1 is formed by splicing two identical semicircles to facilitate the opening and closing of the insulation manhole cover. Of course, the manhole cover body 1 can also be a full circle.

[0034] Continue to refer to Figure 1As shown, the first semicircular manhole cover 101 and the second semicircular manhole cover 102 are both provided with a first handle 8. Specifically, by providing the first handle 8 on both semicircular manhole covers, it is convenient for construction workers to take and place the first semicircular manhole cover 101 and the second semicircular manhole cover 102.

[0035] To ensure the integrity of the thermal insulation manhole cover, the first installation cover 5 and the second installation cover 6 are both made of pine wood, and the thickness is 3 cm, the diameter of the first installation cover 5 is 10 cm, and the diameter of the second installation cover 6 is 15 cm. Specifically, the first installation cover 5 and the second installation cover 6 are made of the same material and thickness as the manhole cover body 1, and the diameters of the first installation cover 5 and the second installation cover 6 are respectively the same as the diameters of the first opening 3 and the second opening 4, so as to ensure that the first installation cover 5 and the second installation cover 6 can be installed in the first opening 3 and the second opening 4, so that the manhole cover body 1 forms a plane.

[0036] Reference Figure 2 As shown, the first mounting cover 5 and the second mounting cover 6 are both provided with a second handle 7, and the connection between the second handle 7 and the first mounting cover 5 and the second mounting cover 6 is extended to the manhole cover body 1 to be connected to the manhole cover body 1. Specifically, by providing the second handle 7 on the first mounting cover 5 and the second mounting cover 6, it is convenient to take and place the first mounting cover 5 and the second mounting cover 6, and at the same time, both ends of the second handle 7 are extended to the manhole cover body 1, so that the second handle 7 can be fixed to the manhole cover body 1, and the first mounting cover 5 and the second mounting cover 6 are fixed to the manhole cover body 1.
