[0033] The grass planting well cover, also known as the grass pot well cover, concave well cover, green well cover or invisible well cover, one of the main functions of the grass planting well cover is to protect the well mouth, prevent people or objects from falling into the well and causing injury or damage to the water well equipment. Compared with the traditional well cover, the grass planting well cover can increase the urban green area by planting flowers and plants on the well cover while ensuring the safety of the well mouth. These plants can absorb carbon dioxide in the air and release oxygen, which helps to improve the urban air quality; It can also significantly improve the overall aesthetics of the urban green belt, making the well cover more visually concealed and reducing the 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 planting well cover need to be watered regularly, however, due to the usually concealed and difficult to access location of the well cover, watering work can become difficult and time-consuming; At the same time, since the roots of the plants on the grass planting well cover cannot reach deep into the earth to draw water, and the soil space for the growth of the plants on the grass planting well cover is limited, if watering is neglected, it can lead to poor growth or death of the plants, making the planting soil above the well cover exposed, affecting the aesthetics, thus requiring constant replacement of the plants on the well cover, resulting in a large workload for the staff and increasing the planting cost.

[0035] In order to improve the above technical problems to some extent, the present application provides a grass planting well cover and well mouth assembly, which can automatically water the plants according to the water content of the planting soil, so that the plants grow well, reducing the frequency of replacing the plants, thereby reducing the workload of the staff and the planting cost.

[0036] The embodiments of the present application will be described below with reference to the accompanying drawings:

[0037] Please refer to Figure 1 The present application provides a grass planting well cover 11 applied to a well mouth 12. The grass planting well cover 11 provided by 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, reducing the frequency of replacing the plants 20, thereby reducing the workload of the staff and the planting cost.

[0038] It should be noted that the structure of the grass-planting manhole cover 11 is described in the embodiments of the present application, and the working state of the grass-planting manhole cover 11 is taken as the reference, that is, the state of the grass-planting manhole cover 11 installed on the well mouth 12. The orientation description is also taken as the reference.

[0039] Please refer to Figure 1 and Figure 2 In the embodiments of the present application, the grass-planting manhole cover 11 includes a cover body 100, a planting soil 200, a water storage tank 300 and a control unit 400. The cover body 100 is used to be installed on the well mouth 12, and the cover body 100 has a receiving cavity 110. 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. The water storage tank 300 has a water storage cavity 310 and a first water outlet 311 communicating with the water storage cavity 310. The water storage cavity 310 is used to store water. The control unit 400 can communicate or separate the first water outlet 311 and the receiving cavity 110.

[0040] In the embodiments of the present application, the grass-planting manhole cover 11 includes a cover body 100, a planting soil 200, a water storage tank 300 and a control unit 400. The cover body 100 is used to be installed on the well mouth 12, and the cover body 100 has a receiving cavity 110. 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. The water storage tank 300 has a water storage cavity 310 and a first water outlet 311 communicating with the water storage cavity 310. The water storage cavity 310 is used to store water. The control unit 400 can communicate or separate the first water outlet 311 and the receiving cavity 110.

[0041] The cover body 100 is a basic component of the grass-planting manhole cover 11, which is used to provide installation and protection for at least other components of the grass-planting manhole cover 11. The cover body 100 is installed on the well mouth 12 through a support frame. The receiving cavity 110 is located in the well mouth 12, and the top of the receiving cavity 110 has an open mouth. The planting soil 200 is arranged in the receiving cavity 110, so as to be used for planting plants 20. Of course, in order to be beautiful, the top surface of the planting soil 200 is basically flush with the surrounding ground.

[0042] The water storage cavity 310 is used for water storage. The water storage in the water storage cavity 310 can be achieved in two ways. One is that a non-closed structure is arranged on the top of the water storage cavity 310. In this way, when it rains, rainwater can enter the water storage cavity 310 through the opening on the top of the containing cavity 110. Of course, the grass planting well cover 11 also comprises a filter screen 320. The top of the water storage tank 300 is open. The filter screen 320 is installed on the water storage tank 300 and covers the opening to reduce impurities entering the water storage tank 300. The other way is that a hose 150 can be arranged in the water storage cavity 310. The hose 150 extends out of the cover plate and is connected to a water source. The staff regularly supplies water to the water storage cavity 310 through the hose 150. The upper part of the water storage tank 300 can be provided with an overflow port 313 communicating with the water storage cavity 310. When the water in the water storage cavity 310 is full, the water can flow out of the overflow port 313. The lower part of the containing cavity 110 can be provided with a drain port 120 communicating with the containing cavity 110 to drain excess water.

[0043] The control unit 400 can communicate or separate the first water outlet 311 and the containing cavity 110. That is, when the control unit 400 communicates the first water outlet 311 and the containing cavity 110, the water in the water storage cavity 310 enters the containing cavity 110 through the first water outlet 311 to supply water for the planting soil 200 in the containing cavity 110, thereby realizing irrigation of the plants 20. When the control unit 400 separates the first water outlet 311 and the containing cavity 110, the water in the water storage cavity 310 cannot enter the containing cavity 110.

[0044] It can be understood that the total amount of the planting soil 200 in the containing cavity 110 is unchanged. The heavier the weight of the planting soil 200, the higher the water content. 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 of sufficiency and deficiency, 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 the plants 20, the type of the soil, the climate condition, etc. It can be set according to the actual situation and is not limited.

[0045] In the case where the weight of the planting soil 200 is greater than the first set value, the water content of the planting soil 200 is high at this time, irrigation is not needed, and the control unit 400 separates the first water outlet 311 and the containing cavity 110, thereby avoiding the water in the water storage cavity 310 from entering the containing cavity 110, and avoiding overwatering. In the case where 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 at this time, the control unit 400 communicates the first water outlet 311 and the containing cavity 110, so that the water in the water storage cavity 310 flows into the containing cavity 110, thereby irrigating the plants 20 and making the plants 20 grow normally.

[0046] The grass-planting well cover 11 provided by the embodiment of the present application can automatically water the plants 20 according to the water 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 arranged in the accommodating cavity 110, the control unit 400 has a water inlet 424 in communication with the accommodating cavity 110, and the control unit 400 can move relative to the water storage groove 300 with the change of the weight of the planting soil 200, so that the water inlet 424 moves relative to the first water outlet 311.

[0048] In the case that the weight of the planting soil 200 is less than or equal to the first set value, the water inlet 424 corresponds to and communicates with the first water outlet 311; in the case that 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 groove 300 with the change of the weight of the planting soil 200, so that the water inlet 424 moves relative to the first water outlet 311, that is, the control unit 400 realizes the communication 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 at this time, and irrigation is not needed, the control unit 400 is arranged in misalignment with the first water outlet 311 by moving the water inlet 424, so that the water in the water storage cavity 310 can be prevented from entering the accommodating cavity 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 low at this time, the control unit 400 is arranged in alignment with the first water outlet 311 by moving the water inlet 424, so that the water in the water storage cavity can flow into the accommodating cavity 110, thereby the plants 20 can be irrigated, so that the plants 20 grow normally.

[0050] In some embodiments, the control unit 400 includes a first elastic member 410 and a movable plate 420, the water inlet 424 is arranged on the movable plate 420, one end of the movable plate 420 is in contact with the inner wall of the accommodating cavity 110, and the other end is in contact with the water storage groove 300, so as to divide the accommodating cavity 110 into a first space 111 and a second space 112, the first elastic member 410 is arranged in the first space 111 and connected with the movable plate 420, the second space 112 is arranged with the planting soil 200, and the water inlet 424 communicates with the second space 112.

[0051] In the case that the weight of the planting soil 200 is less than or equal to the first set value, the water inlet 424 corresponds to and communicates with the first water outlet 311; in the case that 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.

[0052] Obviously, the first space 111 and the second space 112 are arranged side by side in the vertical direction, and since the planting soil 200 is arranged in the second space 112, the planting soil 200 needs to be flush with the ground, so the second space 112 is arranged above the first space 111, so 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 extended and 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, 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 is arranged in a staggered manner with the first water outlet 311; and when the water content of the planting soil 200 is low, the weight is light, the first elastic member 410 is elastically released, overcoming 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, 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, it is not necessary to control the movement of the movable plate 420 under the change of the weight of the planting soil 200 by means of electronic devices such as gravity sensors and control systems, so that the structure of the grass planting well cover 11 is simpler, the manufacturing cost is lower, and it is not easy to be damaged. 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 is not completely separated from the first space 111 and the second space 112, and there is a communication part between the first space 111 and the second space 112, and the first space 111 also has the planting soil 200, of course, with the movement of the movable plate 420, the volume of the first space 111 and the second space 112 also changes, and the movable plate 420 moves spontaneously under the change of the weight of the planting soil 200 in the second space 112.

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

[0057] In some embodiments, the movable plate 420 has a first connecting end 421, a connecting portion 422, and a second connecting end 423, the connecting portion 422 connecting the first connecting end 421 and the second connecting end 423, the first connecting end 421 and the second connecting end 423 being arranged at an angle with the connecting portion 422, the first connecting end 421 being in contact with the inner wall of the accommodating cavity 110, the second connecting end 423 being in contact with the water storage groove 300, and the connecting portion 422 dividing the accommodating cavity 110 into the first space 111 and the second space 112, the water inlet 424 being arranged at the second connecting end 423.

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

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

[0060] The first space 111 is at the bottom of the grass planting well cover 11, so it is necessary to arrange the water filtering geotextile 130 and the ceramic particle water repellent layer 140 in the first space 111. The water filtering geotextile 130 has two layers, and the ceramic particle water repellent layer 140 is arranged between the two layers of water filtering geotextile 130. The planting soil 200 is arranged above the water filtering geotextile 130 and the ceramic particle water repellent layer 140. The water filtering geotextile 130 is used for filtering water to prevent soil loss in the well cover, thereby blocking the drainage holes and the pores of the ceramic particles. The ceramic particle water repellent layer 140 is used for water repellence and air permeability. Firstly, it can absorb part of the water, and when it is dry, it can supply water to the soil through transpiration and capillary action; secondly, it can increase air at the bottom of the soil to prevent root rot.

[0061] In order to avoid the expansion of the first elastic member 410 being interfered and the movement of the movable plate 420 being affected, a separate installation channel 113 is arranged in the first space 111, which is separated from the water filtering geotextile 130, the ceramic hydrophobic layer 140 and the planting soil 200, and the first elastic member 410 is arranged in the installation channel 113.

[0062] Please refer to Figure 2 and Figure 3 In some embodiments, the grass planting well cover 11 further comprises an inspiration unit 500 and a baffle 600, the inspiration unit 500 is arranged on the side of the water storage tank 300, and the baffle 600 is arranged in the water storage tank 300 and connected with the inspiration unit 500; the inspiration unit 500 is located above the first water outlet 311, the water storage tank 300 further has a second water outlet 312 which is in communication with the water storage cavity 310 and is located below the first water outlet 311, and the baffle 600 blocks the second water outlet 312.

[0063] In the case that the weight of the planting soil 200 is less than or equal to a second set value, the movable plate 420 can move relative to the water storage 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 in communication with 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 storage tank 300 is greater than the height of the first water outlet 311, the water in the water storage tank 300 can flow into the containing cavity 110 through the first water outlet 311 when the water inlet hole is in communication with the first water outlet 311, and when the water storage tank 300 is used for a long time and water is not added in time, the water level in the water storage tank 300 will be lower than the height of the first water outlet 311, so that even if the movable plate 420 moves upward and the water inlet hole is in communication with the first water outlet 311, the water in the water storage tank 300 cannot flow out, and 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 continues to move upward and touches the inspiration unit 500, so that the inspiration unit 500 drives the baffle 600 to move, so that the second water outlet 312 is in communication with the second space 112, so that the water in the water storage tank 300 can flow into the containing cavity 110 through the second water outlet 312, and water is supplied to the planting soil 200.

[0066] Specifically, the first water outlet 311 can be arranged at the bottom of the water storage tank 300, so that the water in the water storage tank 300 can be completely discharged, thereby the water in the water storage tank 300 can be fully utilized. The second set value is set according to actual conditions, and the installation position of the heuristic unit 500 can be designed according to the set second set value.

[0067] In some embodiments, the heuristic unit 500 comprises a second elastic member 510, a first roller 520, a mounting member 530, and a connecting assembly. The mounting member 530 is mounted to the side of the water storage tank 300, the first roller 520 is rotatably arranged on the mounting member 530, the upper part of the second elastic member 510 is connected to the first roller 520, and the lower part 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 the case that 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 storage 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 can be a spring. Since the upper part of the second elastic member 510 is connected to the first roller 520, and the lower part 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 in communication with the containing cavity 110.

[0070] In some embodiments, the connecting assembly comprises a transmission rope 540, a second roller 550, and a traction rope 560. The second roller 550 is rotatably arranged in the water storage tank 300. The transmission rope 540 is in transmission connection with 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 in transmission connection with 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, so that the rotation of the first roller 520 drives the second roller 550 to rotate, and the rotation of the second roller 550 drives the baffle 600 to rise through the traction rope 560, so that the second water outlet 312 is in communication with the containing cavity 110.

[0072] In order to protect the traction rope 560, a traction sleeve 570 can also be arranged 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 arranged in the traction sleeve 570.

[0073] In some embodiments, to ensure that the water storage tank 300 has good sealing performance, rubber sealing sleeves need to be added to the first water outlet 311, the second water outlet 312, the overflow port 313 and the drain port 120, effectively preventing the exosmosis of internal moisture, thereby maintaining good air tightness and water tightness.

[0074] Based on the same inventive concept, the embodiment of the present application also provides a wellhead assembly 10, comprising a wellhead 12 and the grass-planting well cover 11 described above. The wellhead assembly 10 provided by the embodiment of the present application has the same beneficial effects as the grass-planting well cover 11 described above, and will not be described here again.
