DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture.

[0033] Grass manhole covers, also known as grass pot manhole covers, concave manhole covers, green manhole covers or invisible manhole covers, have one of the main functions of protecting the wellhead to prevent people or objects from falling into the well and causing injury or damaging the well equipment. Compared with traditional manhole covers, grass manhole covers can increase the urban greening area by planting flowers and plants on the manhole covers while ensuring the safety of the wellhead. These plants can absorb carbon dioxide in the air and release oxygen, which helps to improve the air quality in the city; they can also significantly improve the overall beauty of the urban green belt, making the manhole cover more visually concealed and reducing damage to the urban landscape. It is an indispensable part of urban greening and municipal construction, providing a strong guarantee for the beauty and safety of the city.

[0034] The plants on the grass manhole covers need to be watered regularly. However, since the manhole covers are usually hidden and difficult to access, watering may become difficult and time-consuming. At the same time, since the roots of the plants on the grass manhole covers cannot penetrate deep into the soil to absorb water, and the soil space for the plants on the grass manhole covers to grow is limited, if watering is neglected, it may lead to poor plant growth or death, exposing the planting soil above the manhole covers, affecting the aesthetics, and thus requiring constant replacement of the plants on the manhole covers, resulting in a large workload for the staff and increased planting costs.

[0035] In order to improve the above technical problems to a certain extent, the embodiment of the present application provides a grass-planting manhole cover and a wellhead assembly, which can automatically water the plants according to the moisture content of the planting soil, so that the plants grow well, reduce the frequency of plant replacement, and thus reduce the workload of staff and planting costs.

[0036] The following is a description of the embodiments of the present application in conjunction with the accompanying drawings:

[0037] See also Figure 1 The embodiment of the present application provides a grass-planting manhole cover 11, which is applied to a manhole 12. The grass-planting manhole cover 11 provided in the embodiment of the present application can automatically water the plants 20 according to the weight of the planting soil 200, so that the plants 20 grow well, reduce the frequency of replacing the plants 20, and thus reduce the workload of the staff and the planting cost.

[0038] It should be noted that when describing the structure of the grass manhole cover 11 in the embodiment of the present application, the working state of the grass manhole cover 11, that is, the state when the grass manhole cover 11 is installed at the wellhead 12, is used as the basis, and the orientation description is also based on the working state of the grass manhole cover 11.

[0039] See also Figure 1 and Figure 2 In the embodiment of the present application, the grass-planting manhole cover 11 includes a cover body 100, planting soil 200, a water storage tank 300 and a control unit 400. The cover body 100 is used to be installed on the wellhead 12, and the cover body 100 has a receiving cavity 110, and the planting soil 200 is arranged in the receiving cavity 110 for planting plants 20; the water storage tank 300 and the control unit 400 are installed in the receiving cavity 110, and the water storage tank 300 has a water storage cavity 310 and a first water outlet 311 connected to the water storage cavity 310, and the water storage cavity 310 is used to store water, and the control unit 400 can connect or separate the first water outlet 311 and the receiving cavity 110.

[0040] In which, when the weight of the planting soil 200 is less than or equal to the first set value, the control unit 400 connects the first water outlet 311 and the accommodating chamber 110 so that the water in the water storage chamber flows into the accommodating chamber 110; when the weight of the planting soil 200 is greater than the first set value, the control unit 400 separates the first water outlet 311 and the accommodating chamber 110.

[0041] The cover 100 is a basic component of the grass-planting manhole cover 11, and is used to provide installation and protection for at least other components of the grass-planting manhole cover 11. The cover 100 is installed on the wellhead 12 through a support frame, and the accommodating cavity 110 is located in the wellhead 12, and the top of the accommodating cavity 110 has an opening, and the planting soil 200 is arranged in the accommodating cavity 110, so that it can be used to plant plants 20. Of course, for aesthetics, the top surface of the planting soil 200 is basically flush with the surrounding ground.

[0042] The water storage chamber 310 is used to store water. The water storage chamber 310 can be stored in two ways. One is to set a non-enclosed structure at the top of the water storage chamber 310. In this way, when it rains, rainwater can enter the water storage chamber 310 through the opening at the top of the accommodating chamber 110. Of course, the grass-planting manhole cover 11 also includes a filter 320. The top of the water storage tank 300 is open. The filter 320 is installed on the water storage tank 300 and covers the opening to reduce impurities from entering the water storage tank 300. The second is to set a hose 150 in the water storage chamber 310. The hose 150 extends out of the cover plate and is connected to the water source. The staff regularly supplies water to the water storage chamber 310 through the hose 150. The upper part of the water storage tank 300 can be provided with an overflow port 313 connected to the water storage chamber 310. When the water in the water storage chamber 310 is full, the water can flow out from the overflow port 313. A drain port 120 communicating with the accommodating chamber 110 may be disposed at the lower portion of the accommodating chamber 110 to drain excess water.

[0043] The control unit 400 can connect or separate the first water outlet 311 and the containing chamber 110, that is, when the control unit 400 connects the first water outlet 311 and the containing chamber 110, the water in the water storage chamber 310 enters the containing chamber 110 through the first water outlet 311, and supplies water to the planting soil 200 in the containing chamber 110, thereby achieving watering of the plant 20; when the control unit 400 separates the first water outlet 311 and the containing chamber 110, the water in the water storage chamber 310 cannot enter the containing chamber 110.

[0044] It is understandable that the total amount of the planting soil 200 in the accommodating cavity 110 remains unchanged, and the heavier the weight of the planting soil 200, the higher the water content, and the lighter the weight of the planting soil 200, the lower the water content. When the water content of the planting soil 200 is at the critical point between sufficient and insufficient, the weight value of the planting soil 200 at this time is the first set value. The first set value of the weight of the planting soil 200 is related to the total amount of the planting soil 200, the type of plant 20, the soil type, the climatic conditions, etc., and can be set according to the actual situation, and there is no limitation on this.

[0045] When the weight of the planting soil 200 is greater than the first set value, the water content of the planting soil 200 is relatively high and no irrigation is required. The control unit 400 separates the first water outlet 311 and the accommodating chamber 110, thereby preventing the water in the water storage chamber 310 from entering the accommodating chamber 110, thereby avoiding overwatering. When the weight of the planting soil 200 is less than or equal to the first set value, the water content of the planting soil 200 is relatively low. The control unit 400 connects the first water outlet 311 and the accommodating chamber 110, so that the water in the water storage chamber flows into the accommodating chamber 110, thereby irrigating the plant 20 and allowing the plant 20 to grow normally.

[0046] That is, the grass-planting manhole cover 11 provided in the embodiment of the present application can automatically water the plants 20 according to the moisture content of the planting soil 200, so that the plants 20 grow well, thereby reducing the frequency of replacing the plants 20 and reducing the workload of the staff and the planting cost.

[0047] In some embodiments, the control unit 400 is movably disposed in the accommodating cavity 110, and the control unit 400 has a water inlet 424 communicated with the accommodating cavity 110. The control unit 400 can move relative to the water storage tank 300 as the weight of the planting soil 200 changes, so that the water inlet 424 moves relative to the first water outlet 311;

[0048] Among them, when the weight of the planting soil 200 is less than or equal to the first set value, the water inlet 424 corresponds to and is connected to the first water outlet 311; when the weight of the planting soil 200 is greater than the first set value, the water inlet 424 is misaligned with the first water outlet 311.

[0049] The control unit 400 can move relative to the water storage tank 300 as the weight of the planting soil 200 changes, so that the water inlet 424 moves relative to the first water outlet 311, that is, the control unit 400 realizes the connection or separation of the water inlet 424 and the first water outlet 311 by moving. When the weight of the planting soil 200 is greater than the first set value, the water content of the planting soil 200 is high and no irrigation is required. The control unit 400 moves the water inlet 424 and the first water outlet 311 to avoid the water in the water storage chamber 310 from entering the accommodating chamber 110, thereby avoiding excessive watering; when the weight of the planting soil 200 is less than or equal to the first set value, the water content of the planting soil 200 is low. The control unit 400 moves the water inlet 424 and the first water outlet 311 to align and connect, so that the water in the water storage chamber flows into the accommodating chamber 110, so that the plant 20 can be irrigated and the plant 20 can grow normally.

[0050] In some embodiments, the control unit 400 includes a first elastic member 410 and a movable plate 420, a water inlet 424 is provided on the movable plate 420, one end of the movable plate 420 contacts the inner wall of the accommodating chamber 110, and the other end contacts the water storage tank 300, so as to separate the accommodating chamber 110 into a first space 111 and a second space 112, the first elastic member 410 is provided in the first space 111 and connected to the movable plate 420, the second space 112 is provided with planting soil 200, and the water inlet 424 is communicated with the second space 112;

[0051] The movable plate 420 can move relative to the water storage tank 300 as the weight of the planting soil 200 changes, so that the water inlet 424 moves relative to the first water outlet 311 .

[0052] It is obvious that the first space 111 and the second space 112 are arranged side by side in the vertical direction. Since the planting soil 200 is arranged in the second space 112 and the planting soil 200 needs to be flush with the ground, the second space 112 is arranged above the first space 111, so that the movable plate 420 needs to support the planting soil 200. The first water outlet 311 is arranged on the side of the water storage tank 300, and the first elastic member 410 can be retracted in the vertical direction, so as to drive the movable plate 420 to move up and down, so that the water inlet 424 moves relative to the first water outlet 311.

[0053] When the water content of the planting soil 200 is high and the weight is heavy, the gravity of the planting soil 200 overcomes the elastic force of the first elastic member 410, so that the first elastic member 410 is compressed, thereby driving the movable plate 420 to move downward, so that the water inlet 424 and the first water outlet 311 are misaligned; and when the water content of the planting soil 200 is low and the weight is light, the first elastic member 410 is elastically released, overcomes the gravity of the planting soil 200, thereby driving the movable plate 420 to move upward, so that the water inlet 424 corresponds to and communicates with the first water outlet 311, so as to irrigate the plants 20. Specifically, the first elastic member 410 can be a spring.

[0054] As can be seen from the above, the movable plate 420 moves spontaneously under the change of the weight of the planting soil 200, that is, there is no need to set up electronic devices such as gravity sensors and control systems to control the movable plate 420 to move under the change of the weight of the planting soil 200, thereby making the structure of the grass planting manhole cover 11 simpler, with lower manufacturing costs and less prone to damage. Of course, the setting positions of the water inlet 424 and the first water outlet 311 need to be determined according to the gravity of the planting soil 200 and the elastic potential energy of the first elastic member 410.

[0055] It should be noted that the movable plate 420 does not completely separate the first space 111 and the second space 112. There is a connecting part between the first space 111 and the second space 112, and there is planting soil 200 in the first space 111. Of course, as the movable plate 420 moves, the volumes of the first space 111 and the second space 112 also change, and the movable plate 420 moves spontaneously due to the change in the weight of the planting soil 200 in the second space 112.

[0056] Specifically, the water tank 300 is arranged in the middle of the accommodating cavity 110, and a first water outlet 311 is provided on both sides of the water tank 300. There are two control units 400, and the two control units 400 are arranged on both sides of the water tank 300, and the water inlet 424 of the control unit 400 can be moved relative to the first water outlet 311 on the same side, so that the water tank 300 can supply water to the planting soil 200 more evenly.

[0057] In some embodiments, the movable plate 420 has a first connection end 421, a connection portion 422 and a second connection end 423, the connection portion 422 connects the first connection end 421 and the second connection end 423, the first connection end 421 and the second connection end 423 are both arranged at an angle to the connection portion 422, the first connection end 421 contacts the inner wall of the accommodating cavity 110, the second connection end 423 contacts the water storage tank 300, the connection portion 422 separates the accommodating cavity 110 into a first space 111 and a second space 112, and the water inlet 424 is arranged at the second connection end 423.

[0058] Since the connection part 422 divides the accommodating chamber 110 into the first space 111 and the second space 112, the connection part 422 can be arranged horizontally, so that the first space 111 and the second space 112 are arranged side by side in the vertical direction. The side wall of the water storage tank 300 is arranged vertically, and the inner wall of the accommodating chamber 110 is arranged obliquely, so the first connection end 421 is also arranged obliquely, and the second connection end 423 is also arranged vertically, that is, the angle between the first connection end 421 and the connection part 422 is an obtuse angle, and the second connection end 423 is arranged perpendicular to the connection part 422, so that the first connection end 421 can be attached to the inner wall of the accommodating chamber 110, and the second connection end 423 can be attached to the side wall of the water storage tank 300. When the movable plate 420 moves up and down, the first connection end 421 moves relative to the inner wall of the accommodating chamber 110, and the second connection end 423 moves relative to the side wall of the water storage tank 300, thereby providing guidance for the movement of the movable plate 420, so that the movable plate 420 moves stably.

[0059] In some embodiments, a mounting channel 113 is defined in the first space 111 , and the first elastic member 410 is disposed in the mounting channel 113 .

[0060] The first space 111 is at the bottom of the grass-planted manhole cover 11, so it is necessary to set a water-filtering geotextile 130 and a ceramsite hydrophobic layer 140 in the first space 111. The water-filtering geotextile 130 has two layers, and the ceramsite hydrophobic layer 140 is arranged between the two layers of the water-filtering geotextile 130. The planting soil 200 is arranged above the water-filtering geotextile 130 and the ceramsite hydrophobic layer 140. The water-filtering geotextile 130 is used to filter water and prevent the loss of soil in the manhole cover, thereby blocking the drainage holes and the pores of the ceramsite. The ceramsite hydrophobic layer 140 is used for hydrophobicity and breathability. First, it can absorb part of the water and replenish the soil with water through transpiration and capillary action when it is dry; second, it can add air to the bottom of the soil to prevent root rot.

[0061] That is, since the first space 111 is also provided with a water-filtering geotextile 130, a ceramsite hydrophobic layer 140 and planting soil 200, in order to prevent the expansion and contraction of the first elastic member 410 from being disturbed and affecting the movement of the movable plate 420, an independent installation channel 113 is provided in the first space 111, which is separated from the water-filtering geotextile 130, the ceramsite hydrophobic layer 140 and the planting soil 200, and the first elastic member 410 is arranged in the installation channel 113.

[0062] See also Figure 2 and Figure 3 In some embodiments, the grass-planting manhole cover 11 further includes an inspiration unit 500 and a baffle 600. The inspiration unit 500 is installed on the side of the water storage tank 300. The baffle 600 is arranged in the water storage tank 300 and connected to the inspiration unit 500. The inspiration unit 500 is located above the first water outlet 311. The water storage tank 300 also has a second water outlet 312 connected to the water storage chamber 310. The second water outlet 312 is arranged below the first water outlet 311. The baffle 600 blocks the second water outlet 312.

[0063] In which, when the weight of the planting soil 200 is less than or equal to the second set value, the movable plate 420 can move relative to the water tank 300 and touch the inspiration unit 500, so that the inspiration unit 500 drives the baffle 600 to move, so that the second water outlet 312 is connected to the second space 112, and the second set value is less than the first set value.

[0064] It can be understood that when the water level in the water tank 300 is greater than the height of the first water outlet 311, the water in the water tank 300 can flow into the accommodating chamber 110 through the first water outlet 311 when the water inlet hole is connected to the first water outlet 311. When the water tank 300 is used for a long time and water is not added in time, the water level in the water tank 300 will be lower than the height of the first water outlet 311. In this way, even if the movable plate 420 moves upward so that the water inlet hole is connected to the first water outlet 311, the water in the water tank 300 cannot flow out and cannot supply water to the planting soil 200. Therefore, the water content in the planting soil 200 will continue to decrease, so that the movable plate 420 continues to move upward.

[0065] Since the inspiration unit 500 is located above the first water outlet 311 and the second water outlet 312 is located below the first water outlet 311, the movable plate 420 will touch the inspiration unit 500 when it continues to move upward, so that the inspiration unit 500 drives the baffle 600 to move, thereby connecting the second water outlet 312 with the second space 112. In this way, the water in the water storage tank 300 can flow into the accommodating chamber 110 through the second water outlet 312, thereby supplying water to the planting soil 200.

[0066] Specifically, the first water outlet 311 can be set at the bottom of the water storage tank 300, so that the water in the water storage tank 300 can flow out completely, thereby making full use of the water in the water storage tank 300. The second setting value is set according to actual conditions, and the installation position of the inspiration unit 500 is designed according to the set second setting value.

[0067] In some embodiments, the inspiration unit 500 includes a second elastic member 510, a first roller 520, a mounting member 530 and a connecting assembly, wherein the mounting member 530 is mounted on the side of the water storage tank 300, the first roller 520 is rotatably disposed on the mounting member 530, the upper portion of the second elastic member 510 is connected to the first roller 520, and the lower portion is suspended, one end of the connecting assembly is connected to the first roller 520, and the other end is connected to the baffle 600;

[0068] In which, when the weight of the planting soil 200 is less than or equal to the second set value, the movable plate 420 can move relative to the water tank 300 and compress the second elastic member 510, so that the second roller 550 can rotate under the elastic action of the second elastic member 510 to drive the baffle 600 to move through the connecting assembly.

[0069] The second elastic member 510 may be a spring. Since the upper portion of the second elastic member 510 is connected to the first roller 520 and the lower portion is suspended, when the movable plate 420 moves upward, the second elastic member 510 is compressed, so that the second roller 550 can rotate under the elastic action of the second elastic member 510, thereby driving the baffle 600 to move upward through the connecting assembly, so that the second water outlet 312 is connected to the accommodating chamber 110.

[0070] In some embodiments, the connecting assembly includes a transmission rope 540, a second roller 550 and a traction rope 560. The second roller 550 is rotatably disposed in the water storage tank 300. The transmission rope 540 is connected to the first roller 520 and the second roller 550. One end of the traction rope 560 is connected to the second roller 550, and the other end is connected to the baffle 600.

[0071] Since the transmission rope 540 is connected to the first roller 520 and the second roller 550, one end of the traction rope 560 is connected to the second roller 550, and the other end is connected to the baffle 600, the rotation of the first roller 520 will drive the second roller 550 to rotate, and the rotation of the second roller 550 will drive the baffle 600 to rise through the traction rope 560, so that the second water outlet 312 is connected to the accommodating chamber 110.

[0072] In order to protect the traction rope 560 , a traction sleeve 570 may be further provided in the water storage tank 300 . The traction sleeve 570 is fixedly connected to the water storage tank 300 , and the traction rope 560 is provided in the traction sleeve 570 .

[0073] In some embodiments, in order to ensure that the water storage tank 300 has good sealing performance, it is necessary to add rubber sealing sleeves to the first water outlet 311, the second water outlet 312, the overflow port 313, and the drain port 120 to effectively prevent the infiltration of internal moisture, thereby maintaining good air tightness and water tightness.

[0074] Based on the same inventive concept, the embodiment of the present application further provides a wellhead assembly 10, including a wellhead 12 and the above-mentioned grass-planted manhole cover 11. The beneficial effects of the wellhead assembly 10 provided in the embodiment of the present application are the same as those of the above-mentioned grass-planted manhole cover 11, which will not be repeated here.

[0075] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0076] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
