[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material, such as metal manhole covers, high-strength fiber-reinforced concrete manhole covers, and resin manhole covers. They are generally round. They can be used in green belts, sidewalks, driveways, docks, alleyways, etc.

[0003] For example, application number CN201710706757.6 describes a safety manhole cover, relating to the field of manhole cover technology, used to obtain the positioning location of the manhole cover and improve the safety of the manhole cover body. The main technical solution of this invention is: a safety manhole cover, comprising: a manhole cover body and a connecting module, wherein the manhole cover body has a locator, the locator is connected to the connecting module, and the locator is used to send the position of the manhole cover body to a preset terminal device through the connecting module. This invention is mainly used for sealing manhole openings.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that existing manhole covers, which cannot open automatically, are not conducive to draining water from roads during the flood season.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a flood discharge manhole cover, in order to achieve a more practical purpose. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a flood discharge manhole cover, which solves the problem that existing manhole covers, which cannot open automatically, are not conducive to draining water from roads during the flood season.

[0007] The purpose and function of this flood discharge manhole cover are achieved by the following specific technical means:

[0008] A flood discharge manhole cover, comprising:

[0009] The ring-shaped outer base and the manhole cover body located in the middle of the ring-shaped outer base, with at least two push rods at the bottom of the manhole cover body. The upper end of the push rod is fixedly connected to the manhole cover body, and the push rod is slidably connected to the ring-shaped outer base.

[0010] A water-collecting shell is located at the lower part of the annular outer base. The water-collecting shell is correspondingly set with the push rod. A float is set inside the water-collecting shell. The inner wall of the water-collecting shell and the outer wall of the float are directly provided with a space to contain liquid. The float is fixedly connected to the lower end of the push rod.

[0011] Electric valve one, one end of electric valve one is connected to the space where the ground is located, and the other end of electric valve one is connected to the water accumulation shell;

[0012] Water pressure sensor, used to detect the water pressure of water on the ground;

[0013] When the water pressure sensor detects that the water pressure is greater than the set value, the control chip sends a signal to the control chip, which then sends an opening signal to the electric valve to open the electric valve.

[0014] Furthermore, the manhole cover body is made of carbon fiber, and multiple crossbeams are installed on the inner circumferential wall of the annular outer base.

[0015] Furthermore, the push rod is equipped with a pier head, which is fixedly connected to the pontoon.

[0016] Furthermore, at least one auxiliary float is installed at the bottom of the manhole cover.

[0017] Furthermore, the upper part of the electric valve is connected to a water collection box with an upper opening, and the upper surface of the water collection box is flush with the road surface.

[0018] Furthermore, a mesh cover is installed at the opening of the water collection box.

[0019] Furthermore, the lower part of the water-accumulating shell is connected to an electric valve.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When the water pressure sensor of this invention detects that the water pressure of the surface water reaches a set value, the control chip controls the electric valve to open, allowing the accumulated water to flow into the water collection shell. As the water level in the water collection shell rises, the float pushes the push rod upward, thereby raising the height of the manhole cover and opening it. This achieves automatic opening of the manhole cover to drain the accumulated water. Attached Figure Description

[0031] Example:

[0032] As attached Figure 1 To be continued Figure 4 As shown:

[0033] This utility model provides a flood discharge manhole cover, comprising:

[0034] The annular outer base 11 and the manhole cover body 12 disposed in the middle of the annular outer base 11, wherein at least two push rods 14 are provided at the bottom of the manhole cover body 12, the upper end of the push rods 14 is fixedly connected to the manhole cover body 12, and the push rods 14 are slidably connected to the annular outer base 11.

[0035] A water-collecting shell 13 is disposed at the lower part of the annular outer base 11. The water-collecting shell 13 is correspondingly disposed with the push rod 14. A float 15 is disposed inside the water-collecting shell 13. The inner wall of the water-collecting shell 13 and the outer wall of the float 15 are directly provided with a space for containing liquid. The float 15 is fixedly connected to the lower end of the push rod 14.

[0036] Electric valve 16, one end of which is connected to the space where the ground is located, and the other end of which is connected to the water accumulation shell 13;

[0037] A water pressure sensor is used to detect the water pressure of surface water.

[0038] When the water pressure sensor detects that the water pressure is greater than the set value, the water pressure sensor sends a signal to the control chip, and then the control chip sends an opening signal to the electric valve 16 to open the electric valve 16.

[0039] In this embodiment, when the water pressure sensor detects that the water pressure of the surface water reaches the set value, the control chip controls the electric valve 16 to open, allowing the accumulated water to flow into the water accumulation housing 13.

[0040] When the water level in the water-filled shell 13 rises, the float 15 pushes the push rod 14 upward as the water level rises, thereby raising the height of the manhole cover body 12 to open the manhole cover body 12.

[0041] The manhole cover body 12 is made of carbon fiber, and the inner circumferential wall of the annular outer base 11 is provided with multiple crossbeams 18.

[0042] The manhole cover body 12 is made of carbon fiber to reduce its weight, while multiple crossbeams 18 can increase its load-bearing capacity, so as to ensure the high load-bearing capacity of the manhole cover body 12 while making it easy to open the manhole cover body 12 with less force.

[0043] The push rod 14 is provided with a support head 141, which is fixedly connected to the float 15. The support head 141 can prevent the manhole cover body 12 from floating up and detaching from the annular outer base 11.

[0044] At least one auxiliary float 19 is provided at the bottom of the manhole cover body 12. The auxiliary float 19 increases the buoyancy of the manhole cover body 12 after it is opened, thus assisting in the opening of the manhole cover body 12.

[0045] The electric valve 16 is connected to a water collection box 20 with an upper opening. The upper surface of the water collection box 20 is flush with the road surface, so as to ensure that the road surface is flat while the water can flow smoothly into the water collection box 20.

[0046] A mesh cover 201 is provided at the opening of the water collection box 20. The mesh cover 201 is designed to prevent excessively large impurities from entering the water collection shell 13 and affecting its repeated use. In practical applications, it should also be maintained regularly to ensure its long-term effective operation.

[0047] The lower part of the water-collecting shell 13 is connected to an electric valve 17. The electric valve 17 facilitates the drainage of water in the water-collecting shell 13. When the control chip detects that the water pressure (the water pressure value is determined according to the actual situation; for example, if drainage needs to be started at a water level of 0.5 meters, the water pressure setting value corresponding to 0.5 meters is 5000Pa) rises to the set value, the electric valve 16 is opened, and the electric valve 17 is closed at the same time.

[0048] The formula for calculating water pressure is p = ρgh.

[0049] The specific usage and function of this embodiment are as follows:

[0050] In use, the water collection shell 13 is fixedly buried in the roadbed, the float 15 is placed inside the water collection shell 13, and then the push rod 14 is slidably inserted into the upper part of the water collection shell 13. The lower end of the push rod 14 is fixedly connected to the float 15, and the upper end of the push rod 14 is fixedly connected to the manhole cover body 12. The annular outer base 11 is then fixed to the manhole opening, and the water collection box 20 is fixed in the channel opened next to the manhole opening, so that the upper surface of the water collection box 20 is flush with the ground. The control chip, electric valve 16, and electric valve 27 are electrically connected, and the power supply is connected.

[0051] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
