Description

TECHNICAL FIELD

[0001] The present application relates to a sand-proof rainwater inlet device, in particular to a sand-avoiding and blockage-preventing rainwater inlet device suitable for desert photovoltaic and wind power bases. TECHNICAL BACKGROUND

[0002] With the rapid development of industrialization, extreme weather has attracted widespread attention. In desert areas, especially in desert photovoltaic and wind power base construction, rainwater collection facilities can not only prevent rainwater logging from eroding power generation equipment and facilities, but also have important significance for ecological restoration. Compared with urban road rainwater inlets, rainwater inlets of desert rainwater collection pipe networks are usually set in low-lying places; otherwise it is difficult to collect rainwater. Although there is no problem of heavy vehicle crushing and tree leaves blocking the rainwater well grate (hereinafter referred to as "rainwater grate", the rainwater grate frame is referred to as "grate frame", and the rainwater grate body is referred to as "grate body"), the rainwater inlet is easy to be invaded by wind sand and rainwater flow sand (hereinafter referred to as "rain sand"). In addition, due to the low-lying position of the rainwater inlet, the slope of the rainwater pipe network is relatively gentle. The sand deposited at the lower part of the well chamber is easy to accumulate in the rainwater pipe network, causing poor water flow and even water logging. It is not only related to the safe operation of power plant equipment, but also related to the problems of rainwater collection effect and water storage facility capacity.

[0003] The "Chikungunya fever" that occurred in Foshan City and Guangzhou City of Guangdong Province this autumn is a mosquito-borne disease. There is a great relationship between mosquito breeding in rainwater inlets and rainwater ditches, and the local relevant management departments require the installation of mosquito-proof screens in rainwater inlets and rainwater ditches. The defect is that it is easy to cause blockage and water logging when heavy rain falls.

[0004] The rainwater inlet shown in the rainwater inlet atlas approved and issued by the Ministry of Housing and Urban-Rural Development of the People's Republic of China (Atlas No.: 16S518 Rainwater Inlet.pdf; Approval No.: Jianzhihan

[2016] (No. 168)) is a lower rainwater inlet pipe (hereinafter referred to as "rainwater inlet pipe") opened in the lower part of the side wall of the well body. It can be considered as a kind of lower rainwater inlet pipe. It is not only beneficial to drainage, but also can prevent mosquito-borne diseases caused by residual water after rain. Therefore, it is only suitable for use in areas with more rain. If it is set in a desert area with less rain, the wind sand falling into the well chamber and the rain sand flowing into the well chamber are easy to flow into the rainwater pipe network, causing blockage and water logging.

[0005] The defects of the sand and rain water inlet device of the invention patent application No. 202411042950.0 (application date: July 31, 2024) are: the rain water inlet pipe is located at the lower part of the well body side wall, and a water passing gap 10 is reserved between the partitions of each sand settling area (see paragraphs

[0037] to

[0039] of the specification). It can be understood that due to the large flowability of sand, water can pass through the water passing gap, and sand can also pass through the water passing gap. If the water passing gap is too small, it will affect the effect of collecting rainwater; if the water passing gap is too large, it will cause more sand and soil to flow into the rain water pipe network (see paragraphs

[0039] 8-9 and

[0044] of the specification). It only reduces the flow of sand and soil into the lower rain water inlet pipe 11. It cannot avoid the flow of sand and soil into the lower rain water inlet pipe 11. In addition, in addition to the wind sand falling into the indoor, for the part of the surface soil loose ground with poor vegetation, there is also a problem of rain sand flowing into the well chamber in heavy rain. The technical solution of the application is not found to have the corresponding technical features of intercepting rain sand. In addition, the rain water inlet does not have the functions of preventing mice and avoiding mosquitoes. Once the well chamber is filled with water, it is easy to attract mice and mosquitoes to enter and exit. SUMMARY

[0006] The purpose of the present application is to make up for the deficiencies in the background art, and to solve the problem of rain water inlet falling into wind sand and causing rain sand in the starting part of the rain water pipe network of the desert, especially the desert photovoltaic and wind power base, which leads to poor water flow in the rain water pipe network and even waterlogging. And combining with the actual need of repairing vegetation and preventing mice and mosquitoes in desert areas, a sand-avoiding and anti-blocking rain water inlet device suitable for desert photovoltaic and wind power bases is provided.

[0007] To achieve the above purpose, the sand-avoiding and anti-blocking rain water inlet device suitable for desert photovoltaic and wind power bases provided by the present application is realized by the following technical scheme.

[0008] Further, the rainwater grate can be a sand-avoiding rainwater grate with downward protruding water dripping ribs (hereinafter referred to as "water dripping ribs") arranged on the inner vertical surface of the grate frame (referring to the inner vertical surface along the bottom surface or back rain surface of the grate frame, which is named by searching for Tencent Yuanbao, and will not be repeated hereinafter). The water dripping ribs and the inner wall of the upper part of the well body are provided with a water and sand avoiding cooperation gap (hereinafter referred to as "sand avoiding gap"), which can prevent the rain sand from the well mouth without settling from flowing directly into the upper-avoiding sand rain water inlet pipe.

After the wind and rain, the on-site full-time managers use special tools to routinely clean the damp sand in the well chamber and the sand-blocking groove cavity for seedling and grass growing or use special equipment to extract the water therein for standby.

[0010] Further, the mouth of the sand-blocking well body or the mouth of the sand-blocking funnel-shaped well body or the mouth of the funnel-shaped sand-blocking well body (Note: all are collectively referred to as the mouth of the sand-blocking groove and the well) is provided with a "sand-blocking rainwater gutter" that can intercept rain and sand or a "sand-blocking and sand-avoiding rainwater gutter" that can intercept and avoid rain and sand or a "sand-blocking and sand-shielding rainwater gutter" that can intercept and shield wind and sand.

[0011] Further, the upper part of the well body side wall of the sand-blocking well body or the sand-blocking funnel-shaped well body or the funnel-shaped sand-blocking well body and the upper part of the side wall of the sand-blocking groove or the funnel-shaped sand-blocking groove are provided with an overflow water inlet that can make the rainwater in the sand-blocking groove or the funnel-shaped sand-blocking groove flow into the well chamber or the well chamber of the funnel-shaped well body.

[0012] Further, the well chamber is movably provided with a hand-held sand-collecting well core (hereinafter referred to as a hand-held well core), which is composed of a sand-collecting well core (hereinafter referred to as a well core) whose outer shape matches the inner shape of the well chamber and a well core outer folding edge provided at the mouth of the well core and a handle.

[0013] Further, the sand-blocking groove cavity is movably provided with a hand-held sand-blocking groove core (hereinafter referred to as a hand-held groove core), which is composed of a sand-blocking groove core (hereinafter referred to as a groove core) whose outer shape matches the inner shape of the sand-blocking groove cavity and a groove core outer folding edge provided at the mouth of the groove core and a handle.

[0014] Further, a water-activated mouse and mosquito prevention valve device, such as a curtain valve (hereinafter referred to as a "curtain valve"), a floating core valve (hereinafter referred to as a "floating valve"), a water wheel valve, etc., can be movably provided between the well mouth and the rainwater gutter of the well body.

[0015] Further, a water-activated mouse and mosquito prevention valve device, such as a curtain valve (hereinafter referred to as a "curtain valve"), a floating core valve (hereinafter referred to as a "floating valve"), a water wheel valve, etc., can be movably provided between the mouth of the funnel-shaped sand-blocking well body and the sand-blocking and sand-shielding rainwater gutter.

[0016] The inventive thinking is reverse thinking. The design principle of the present application is to use the fact that the specific gravity of sand is greater than that of water. The rainwater inlet pipe is arranged on the upper part of the sidewall of the well body to avoid or say away from the sand sinking in the lower part of the well chamber.

[0017] Compared with the background art, the present application has the following beneficial effects: ①The rainwater inlet pipe of the present application is an upper-arranged sand-avoiding rainwater inlet pipe, which not only can avoid the poor water flow and waterlogging caused by the sand sinking in the lower part of the well chamber flowing into the rainwater pipe network through the rainwater inlet pipe, but also can ensure the water collection effect and facilitate the safe operation of the power generation facility; ②The sand-blocking groove attached to the outer wall of the well chamber can further prevent the rain sand from directly flowing into the well chamber and the rainwater pipe network; ③The rainwater grate is a sand-blocking and sand-avoiding rainwater grate, which can further avoid the wind sand from falling into the well chamber and prevent the rain sand from directly flowing into the rainwater pipe network; ④The well chamber can be regarded as a small water cellar, which serves as a supplement to the rainwater collection facility and promotes ecological restoration; ⑤It can prevent mice and mosquitoes from entering and exiting the rainwater inlet to spread diseases. The present application also has the advantages of simple structure, accurate effect, low cost, easy implementation, and compliance with the national green development policy.

[0056] Example 1:

[0057] Figure 1 , 2 and 3 show the first embodiment of the present application "sand-avoiding and anti-blocking rainwater inlet device suitable for desert photovoltaic and wind power bases". As shown in Figure 1 and 2 The sand-avoiding and anti-blocking rainwater inlet device 7 of the present application suitable for desert photovoltaic and wind power bases is suitable for being arranged at a low-lying place 6 of a desert area, especially a desert photovoltaic and wind power base with good vegetation restoration (although the area with good vegetation restoration does not have the problem of rain and sand flowing into the well chamber, it is difficult to avoid wind and sand falling into it) for implementing the laying of the starting part of the pipe network for collecting rainwater in the desert area, otherwise it is difficult to collect rainwater. A rainwater grate 3 matched with the well body 9 is arranged on the well mouth 2 of the well body 9 (the rainwater grates of the prior art can be used). The rainwater grate 3 is composed of a grate body 4, a grate frame 5 and a connecting ear groove 11 (for anti-theft). Figure 1 in combination with Figure 2We can determine or understand that the well body 9 is a cylindrical well body. The upper part of the side wall of the well body 9 is provided with one or more sand-avoiding overhanging rainwater inlet pipes 1.0, 1.1, 1.2, 1.3. The outer port of the sand-avoiding overhanging rainwater inlet pipe (referring to the interface located on the upper part of the outer wall of the well body) can be connected through with the corresponding pipe port (which can also be said to be the interface) of the rainwater pipe network of the desert photovoltaic and wind power base (including the connection and intercommunication between adjacent rainwater inlets). The purpose is to enable the inner port of the sand-avoiding overhanging rainwater inlet pipe 1.0, 1.1, 1.2, 1.3 to avoid and be far away from the sand 10 at the lower part of the well chamber 8. After the sandstorm, the on-site full-time personnel uses special tools to routinely clean the sand 10 at the lower part of the well chamber 8. The beneficial effects are: ①When it rains, it can avoid the possible water flow obstruction or even waterlogging caused by the flow of sand 10 at the lower part of the well chamber 8 into the rainwater pipe network from the rainwater inlet pipe; ②It can improve the water collection effect; ③It can prevent the waterlogging from eroding the power generation equipment; ④It can prevent the sand from flowing into the water storage facility, affecting its capacity and causing trouble in cleaning. A seemingly extremely simple and easily thought-of problem. An impact and bondage caused by the "water flows downward, and people walk upward" and the traditional rainwater inlet structure form. The inventor could not understand it after long-term thinking. The solution to the problem comes from a dream, and the mentor teaches "be low-key in life and high-standard in work"… and the inspiration is born.

[0058] As shown in Figure 2 and 3 , relative to the rainwater grate 3, the rainwater grate 12 is a rainwater grate with narrow holes, which is mainly used for small community courtyard rainwater ditches and subway open-air entrance and exit step ladder water barriers (belonging to traditional rainwater grates), and is not intended to mean that one well mouth 2 needs to be provided with two or two kinds of rainwater grates. Instead, it means that the rainwater grate without a connecting ear groove 11 can be used to replace the rainwater grate with a connecting ear groove 3. In other words, the "rainwater grate" described in the present application includes rainwater grates with connecting ear grooves (connecting pieces) and rainwater grates without connecting ear grooves, and also includes rainwater grates with narrow holes. Because there is no problem of tree leaves blocking the rainwater wall in desert areas.

[0059] Figure 1 In combination with Figure 3 , it can be determined or understood that the well body 9 can be a square cylindrical well body, but no matter how the shape of the well body and the rainwater grate changes, the sand-avoiding overhanging rainwater inlet pipe is located at the upper part of the side wall of the well body.

[0060] Note: The setting position of the rainwater inlet, the setting part of the sand-avoiding overhanging rainwater inlet pipe, and the sand-avoiding and anti-blocking principle and beneficial effects of the sand-avoiding overhanging rainwater inlet pipe described in this embodiment will not be described again in the following embodiments.

[0061] Embodiment 2:

[0062] Figure 4 , 5 , 6 and Figure 7The second embodiment of the application "A sand-avoiding and block-preventing rainwater inlet device suitable for desert photovoltaic and wind power bases" is shown. This embodiment is an improvement of the "rainwater grate" based on the first embodiment. As shown in Figure 1 , 4 and 5, a sand-avoiding rainwater grate 14 is arranged on the well head 2 of the well body 9. The rainwater grate is composed of a downward protruding annular water dripping rib 15 arranged on the inner vertical surface of the grate frame. The annular water dripping rib 15 and the inner wall of the upper part of the well body 9 are provided with a sand-avoiding gap 13. This can avoid the rain and sand falling from the well head 2 from directly flowing into the overlying sand-avoiding rainwater inlet pipe 1.0, 1.1, 1.2, 1.3 without settling, which may cause poor water flow in the rainwater pipe network and even waterlogging. The principle is the same as that of the water dripping tile. This embodiment is suitable for use in areas with weak vegetation restoration.

[0063] Figure 6 and 7 The sand-avoiding rainwater grates shown in Figs. 4, 5, 6 and 7 are alternative embodiments of the sand-avoiding rainwater grate 14. Figure 6 is to replace the annular water dripping rib 15 with an annular wavy edge water dripping rib 16. Figure 7 is to replace the annular water dripping rib 15 with a water dripping tile-shaped water dripping rib 17 corresponding to the inner opening of the overlying sand-avoiding rainwater inlet pipe 1.0, 1.1, 1.2, 1.3. By corresponding, it means that the water dripping tile-shaped water dripping rib and the overlying sand-avoiding rainwater inlet pipe are mutually matched in position. By analogy, if the water dripping rib shown in Figs. Figure 4 , 6 or 7 is arranged on the inner vertical surface of the grate frame of the rainwater grate 12 shown in Fig. 3 for sand avoidance and block prevention, it is of course also possible. Figure 3

[0064] Embodiment 3:

[0065] Figure 8 ​The third embodiment of the application "a sand-avoiding and blockage-preventing rainwater inlet device suitable for desert photovoltaic and wind power bases" is shown. This embodiment is an upgrade and improvement based on the first and second embodiments. The movable setting (meaning that it can be taken out and put back in, which will not be repeated below) in the well chamber 8 of the well body 9 has a hand-held well core that matches it. It is composed of a well core core mouth outer fold along that matches the well mouth 2 of the well body 9, a well core 20 with an outer shape that matches the inner shape of the well chamber 8 set on the inner vertical surface of the well core core mouth outer fold along, and a handle 18 set on the well core core mouth. The well core core mouth outer fold along can be placed on the well mouth 2. The upper part of the side wall of the well core 20 is provided with an overflow water inlet 19 corresponding to the inner mouth of the upper sand-avoiding rainwater inlet pipe 1.0, 1.1, 1.2, 1.3, which can make the rainwater in the well core cavity flow into the upper sand-avoiding rainwater inlet 1.0, 1.1, 1.2, 1.3. This embodiment is suitable for use in areas where vegetation restoration is relatively weak. After the wind and rain, the sand-avoiding rainwater inlet is opened, and the hand-held well core is taken out to pour out the sand and wet soil at the lower part of the well core 20 for seedling and grass planting.

[0066] It should be noted that the rainwater inlet 3 shown in Figure 2 or the rainwater inlet 12 shown in Figure 3 can replace the sand-avoiding rainwater inlet of this embodiment with the water droplet-shaped water droplet rib 17, and the annular water droplet rib 15 or the annular wave-shaped water droplet rib 16 shown in Figure 4 or Figure 6 can replace the water droplet-shaped water droplet rib 17 of this embodiment; or the hand-held well core shown in Figure 8 is set in the well chamber 8 of the first or second embodiment, which is acceptable. Further, various new embodiments can be derived. Since the described embodiments are very simple, in order to save resources, no additional drawings are provided.

[0067] Embodiment 4:

[0068] Figure 9 and Figure 10The fourth embodiment of the application "A sand-avoiding and clogging-preventing rainwater inlet device suitable for desert photovoltaic and wind power bases" is shown. One or more than one sand-avoiding rainwater inlet pipe 1.4 (only one is shown in the figure because it is a sectional view) is arranged on the sidewall of the hopper body 27 of the funnel-shaped well body 28. A sand-avoiding rainwater grate 23 that matches the funnel-shaped well body 28 is arranged on the well mouth of the funnel-shaped well body 28, and it is composed of a grate body, a grate frame, and a downwardly protruding annular wave-shaped drip rib 21 arranged on the vertical surface of the grate frame. The sand-avoiding gap 25 is arranged between the annular wave-shaped drip rib 21 and the inner wall of the hopper body 27 of the funnel-shaped well body 28. It can prevent the rain and sand falling from the well mouth from directly flowing into the rainwater pipe network through the sand-avoiding rainwater inlet pipe 1.4 without settling. A portable well core that matches the neck shoulder 26 is movably arranged on the neck shoulder 26 (hereinafter referred to as "neck shoulder". The so-called "hopper body" and "neck shoulder" are named by referring to the structure of a funnel) of the funnel-shaped well body 28, and it is composed of a well core mouth outer folding edge 24 that matches the neck shoulder 26, a well core 29 arranged on the vertical surface of the well core mouth outer folding edge 24, and a handle 22 arranged on the well core mouth. The well core 29 of the present embodiment does not need to be provided with a water inlet 19 on the sidewall of the well core 29 compared with the well core 20 shown in Figure 8 The well core mouth outer folding edge 24 can be placed and attached on the neck shoulder 26, and the purpose is to avoid the inconvenience of cleaning work caused by the sand particles in the rainwater entering the potential gap between the well core 29 and the well chamber. After the wind and rain, the on-site full-time management personnel routinely pours out the wet sand and soil in the cavity of the portable well core for seedling and grass planting.

[0069] It needs to be explained here that the sand-avoiding rainwater grate shown in Figure 4 or the sand-avoiding rainwater grate shown in Figure 7 can replace the sand-avoiding rainwater grate 23 of the present embodiment, or the annular wave-shaped drip rib 21 can be omitted or the rainwater grate 3 or 12 shown in Figure 2 , 3 can replace the sand-avoiding rainwater grate 23 for use in better vegetation restoration sections. These are all possible.

[0071] Figure 11 and Figure 12The fifth embodiment of the application "a sand-avoiding and clogging-preventing rainwater inlet device suitable for desert photovoltaic and wind power bases" is shown. The sand-blocking well body 33 is composed of a well body 34 and a sand-blocking groove 35 attached to the outer wall of the well body 34. One or more sand-avoiding rainwater inlet pipes 1.5 are arranged on the upper part of the side wall of the well body 34. The mouth of the sand-blocking well body 33 (note: the general term for the well mouth and the groove mouth of the sand-blocking groove 35) is provided with a sand-blocking rainwater grate 32 matched therewith, which is composed of a sand-blocking rainwater grate frame 30 and a sand-blocking rainwater grate body 31. The so-called sand-blocking rainwater grate refers to the fact that it can completely cover the well mouth and the groove mouth of the sand-blocking groove. After windy and rainy days, the on-site management personnel uses special tools to routinely clean the moist sand in the lower part of the well chamber and the groove cavity of the sand-blocking groove for seedling and grass growing. This embodiment is suitable for use in pot-shaped depressions with weak vegetation. When the depression is in the form of a groove, the sand-blocking groove can be arranged on one side, both sides, or three sides of the outer wall of the well body 34. In addition, due to the diversity of the natural geographical environment and landforms and the human geographical environment in desert areas, the shape of the sand-blocking groove, including the length, width, height, and number, is not particularly limited, so the sand-blocking groove is not called a sand-blocking well to distinguish it.

[0072] By analogy with the third and fourth embodiments, a portable well bladder and / or a portable groove bladder matched therewith can be added in the well chamber of the well body 34 to make routine sand cleaning work more convenient. In order to save resources, no additional drawings are provided here.

[0073] Example 6:

[0074] Figure 13 and Figure 14 The sixth embodiment of the application "a sand-avoiding and clogging-preventing rainwater inlet device suitable for desert photovoltaic and wind power bases" is shown. The sand-blocking funnel-shaped well body 45 is composed of a funnel-shaped well body 46 and a sand-blocking groove 47 attached to the outer wall of the funnel-shaped well body 46 (which can also be one side, both sides, or three sides). A portable well bladder is movably arranged on the neck shoulder of the funnel-shaped well body 46, which is composed of a well bladder mouth outer fold along matched with the neck shoulder, a well bladder 48 with an outer shape matched with the inner shape of the well chamber below the neck shoulder arranged on the inner vertical surface of the well bladder mouth outer fold along, and a handle 42 arranged at the mouth of the well bladder 48 (a hole for the hand to reach in and grab the handle). A portable groove bladder is movably arranged on the groove mouth of the sand-blocking groove 47, which is composed of a groove bladder mouth outer fold along matched with the groove mouth of the sand-blocking groove, a groove bladder 49 with an outer shape matched with the inner shape of the groove cavity of the sand-blocking groove arranged on the inner vertical surface of the groove bladder mouth outer fold along, and a handle 44 arranged at the mouth of the groove bladder 49. After windy and rainy days, the on-site full-time management personnel takes out the portable well bladder and the portable groove bladder and cleans the moist sand in the cavities for seedling and grass growing. If the sand-blocking groove is arranged on one side, both sides, or three sides of the well body 46, the portable well bladder and the portable groove bladder can be arranged on the outer wall of the well body 46 on the same side, different sides, or all sides. Figure 8 、 9The well core 20, 29, 48 and the slot core 49 are different from the sewage interception basket arranged in the municipal rainwater inlet in that the well core 20, 29, 48 and the slot core 49 are not water-permeable and not leakage. The moist sand in the chamber is very useful for ecological restoration. The funnel-shaped well body 46 is provided with one or more than one upper sand-avoiding rainwater inlet pipe 1.6 which can be connected and penetrated with the corresponding pipe orifice of the rainwater pipe network of the desert photovoltaic and wind power base. When the upper sand-avoiding rainwater inlet pipe on the side wall of the funnel-shaped well body 46 is two or more than two, it can be used for the connection and penetration of double or multiple sand-avoiding and anti-blocking rainwater inlet devices; or for the connection and intercommunication between single sand-avoiding and anti-blocking rainwater inlet devices. The sand-blocking funnel-shaped well body 45 is provided with a sand-blocking and sand-avoiding rainwater grate 40 which is matched with the sand-blocking funnel-shaped well body 45. The sand-blocking and sand-avoiding rainwater grate 40 is composed of a sand-blocking and sand-avoiding rainwater grate frame 36, a slot grate body 37, a well grate frame 38, a well grate body 41 and a ring-shaped dripping edge 39 arranged on the vertical surface of the well grate frame 38. Of course, the dripping edge shown in Figure 6 or Figure 7 can be used to replace the ring-shaped dripping edge 39. The ring-shaped dripping edge 39 is arranged between the sand-blocking and sand-avoiding rainwater grate 40 and the inner wall of the funnel-shaped well body 46. The embodiment is suitable for the weak vegetation restoration of the ground.

[0075] It should be noted that there are two cases, ① when the sand-blocking slot is too long, too wide or too high, more than one slot core can be placed together in the sand-blocking slot for easy removal, because the wet sand and wet soil are more obvious than the leaves in the municipal rainwater inlet sewage interception frame, so the number of slot cores in the sand-blocking slot is not particularly limited; ② if the sand-blocking rainwater grate 32 shown in Figure 11 、 12 is used instead of the sand-blocking and sand-avoiding rainwater grate 40 of the embodiment, it is of course possible.

[0076] Embodiment 7:

[0077] Figure 15 and Figure 16The seventh embodiment of the application "a sand-avoiding and clogging-preventing gutter device suitable for desert photovoltaic and wind power bases" is shown. The funnel-shaped sand-blocking well body 61 is composed of a funnel-shaped well body 64 and a funnel-shaped sand-blocking groove 63 attached to the outer wall of the funnel-shaped well body 64. The mouth of the funnel-shaped sand-blocking well body 61 (note: a general term for the well mouth of the funnel-shaped well body 64 and the groove mouth of the funnel-shaped sand-blocking groove 63) is provided with a sand-blocking and sand-preventing rainwater grate 52 that matches it. The sand-blocking and sand-preventing rainwater grate 52 is composed of a sand-blocking and sand-preventing rainwater grate frame 55, a well mouth cover plate 53 that matches the well mouth of the funnel-shaped well body 64, and a groove grate body 54 that matches the groove mouth of the funnel-shaped sand-blocking groove 63. The upper part of the funnel-shaped well body 64 is provided with an upper-arranged sand-avoiding gutter pipe 1.7, 1.8 that can be connected to the corresponding interface of the desert rainwater pipe network. The upper-arranged sand-avoiding gutter pipe 1.7, 1.8 can be used to connect and pass through between double-grate or multi-grate sand-avoiding and clogging-preventing gutter devices, or between single sand-avoiding and clogging-preventing gutter devices. The well mouth cover plate 53 can prevent wind sand from falling into the well chamber of the funnel-shaped well body 64, and can also prevent rain sand from directly flowing into the well chamber and the upper-arranged sand-avoiding gutter pipe 1.7, 1.8 from the well mouth, thus achieving sand-blocking and sand-avoiding. The neck shoulder 50 of the funnel-shaped well body 64 is movably provided with a hand-held well core, which is composed of a well core mouth outer folding edge 51 that matches the neck shoulder 50 of the funnel-shaped well body 64, and a well core 62 that is provided on the inner vertical surface of the well core mouth outer folding edge 51 and has a handle 57 at its mouth. The neck shoulder 60 of the funnel-shaped sand-blocking groove 63 is movably provided with a hand-held groove core, which is composed of a groove core mouth outer folding edge 59 that matches the neck shoulder 60 of the funnel-shaped sand-blocking groove 63, and a groove core 65 that is provided on the inner vertical surface of the groove core mouth outer folding edge 59 and has a handle 58 at its mouth. An overflow-type water inlet 56 is provided on the gap between the upper part of the funnel-shaped well body 64 and the upper part of the funnel-shaped sand-blocking groove 63 (just like the atrial septum and ventricular septum of the heart, hereinafter referred to as "the gap between the hoppers"). When the groove of the funnel-shaped sand-blocking groove 63 is full of rainwater, the rainwater will flow into the cavity of the well core 62 in the funnel-shaped well body 64 through the overflow-type water inlet 56, and then flow into the upper-arranged sand-avoiding gutter pipe 1.7, 1.8 after sand is settled again.

[0078] By analogy with the sixth embodiment, a sand-blocking groove can also be provided on the outer wall around the funnel-shaped well body 64. Since the arrangement is very simple, no separate drawing is provided here to save resources.

[0079] The three sand-avoiding and clogging-preventing lines of this embodiment are: ① preventing sand and soil in the lower part of the well chamber from flowing into the rainwater pipe network from the upper-arranged sand-avoiding gutter pipe; ② the well mouth cover plate 53 can prevent wind sand from falling into the well chamber, and can also prevent rain sand from directly flowing into the well chamber and the upper-arranged sand-avoiding gutter pipe 1.7, 1.8; ③ preventing rain sand from flowing into the well chamber.

[0080] Note: The funnel-shaped sand-blocking well body 61 is different from the sand-blocking funnel-shaped well body 45 in that the well body, sand-blocking groove, and overall vertical section of the former are funnel-shaped, while the vertical section of the latter is funnel-shaped. Please note.

[0081] Example 8:

[0082] Figure 17 and 18 The eighth embodiment of the "sand-avoiding and anti-blocking gutter device suitable for desert photovoltaic and wind power bases" of the present application is shown. This embodiment is an improvement based on the seventh embodiment ( Figure 15 , 16 ). A curtain valve 68 (one of the specific embodiments of the water-activated rat-proof and mosquito-avoiding valve device) is movably arranged between the mouth of the funnel-shaped sand-blocking well body 61 and the sand-blocking screen gutter 52 (note: refers to the upper part of the mouth of the funnel-shaped sand-blocking well body 61 and the lower part of the sand-blocking screen gutter 52). It is composed of a curtain valve frame 70 matching the mouth of the funnel-shaped sand-blocking well body 61, a water guide groove 69 matching the funnel-shaped sand-blocking groove 63 on the inner vertical surface (the name is derived from the Tencent Yuanbao platform, which refers to the inner vertical surface along the bottom or back rain surface) of the curtain valve frame 70 (the so-called curtain valve frame refers to the common frame of the water guide groove 69 and the water falling groove 66), a water falling groove 66, and a curtain door leaf 71 arranged on the free edge of the water guide groove. The free edge of the water guide groove is located above the free edge of the water falling groove and away from the free edge of the water falling groove to form a water falling door hole 67. The curtain door leaf 71 can automatically close the water falling door hole 67 under the action of gravity to prevent rats and mosquitoes from freely entering and exiting the funnel-shaped sand-blocking groove 63. When it rains, the rainwater falling from the funnel-shaped sand-blocking groove 63 flows into the water falling groove 66 through the water guide groove 69; the curtain door leaf 71 can automatically open the water falling door hole 67 to collect rainwater under the pressure of rainwater and water flow. After the rainwater in the funnel-shaped sand-blocking groove 63 is full, it will flow into the portable well core in the well chamber 64 through the overflow water guide 56, and then flow into the upper sand-avoiding gutter pipe 1.7, 1.8 after sand is settled again. It can not only prevent sand from flowing into the rainwater pipe network, but also prevent rats and mosquitoes.

[0083] In addition, the funnel-shaped sand-blocking well body 61 can be considered as a small water cellar, which serves as a supplement to the desert rainwater collection facility and increases the capacity. The curtain valve 68 and the well cover plate 53 are equivalent to a sealing cover, which can store the humid sand and rainwater in the well chamber and the funnel-shaped sand-blocking groove 63, and prevent it from drying out for use when necessary.

[0084] Example 9:

[0085] Figure 19 and Figure 20The ninth embodiment of the application is shown. This embodiment is another form of improvement based on the seventh embodiment (see Figs. 7 and 8). Figure 15 Figure 16 The floating valve 72 is composed of a water falling groove frame 74 matched with the mouth of the funnel-shaped sand blocking well body 61, a water falling groove 73 set on the vertical surface of the water falling groove frame 74 and matched with the funnel-shaped sand blocking groove 63, a conical groove neck 76 and a floating ball 75 set in the cavity of the conical groove neck 76 and capable of floating up from the upper inlet and not falling off from the lower outlet. The use method, function and advantages are as follows: ① After the wind sand or sandstorm, the sand blocking and sand shielding rain gutter 52 is opened to take out the floating valve 72 and pour out the sand in the water falling groove 73. It can be understood that the floating valve 72 has the functions of shielding the wind sand from falling into the sand blocking groove and collecting the wind sand; ② The wet sand and wet soil in the sand blocking groove 63 and the rainwater in the well chamber of the funnel-shaped well body 64 can be stored to prevent wind drying and help ecological restoration; ③ The mice and mosquitoes can be prevented from entering and leaving the sand blocking groove 63 to spread diseases.

[0086] Embodiment 10

[0087] Figure 21 Figure 22 The tenth embodiment of the application is shown. This embodiment is an improvement based on the third embodiment. A floating valve 77 matched with the well mouth 2 is movably arranged between the outer fold of the well gall 20 of the well mouth 2 and the rain gutter 12. The floating valve 77 is composed of a water falling groove frame 79, a water falling groove 78 set on the vertical surface of the water falling groove frame 79, a conical groove neck 81 (its shape is like a toy sand leakage bucket in a children's park sand pool) set at the bottom of the water falling groove 78 and a floating ball 80 movably arranged in the cavity of the conical groove neck 81 and capable of floating up from the upper inlet and not falling off from the lower outlet. The beneficial effects are as follows: ① The mice and mosquitoes can be prevented; ② When the wind sand falls into the water falling groove 78, the rain gutter 12 is opened to take out the floating valve 77 and pour out the sand; it can be understood that the floating valve 77 has the functions of shielding the wind sand from falling into the well chamber and collecting the sand; ③ The rain sand from the well mouth 2 can be prevented from directly flowing into the overlying sand avoiding rainwater inlet pipe 1.0, 1.1, 1.2 and 1.3, which is another structural form of shielding wind sand and avoiding rain sand; ④ The wet sand, wet soil and rainwater in the well chamber can be stored for use when necessary, which helps ecological restoration.

[0088] ​​This embodiment is an improvement based on embodiment 3. And embodiment 3 is an improvement based on embodiment 1. It can be understood that the float valve 77 in this embodiment can be set between the well mouth 2 and the rainwater gutter of the well body 9 in embodiment 1. By analogy, the float valve 77 in this embodiment can also be set on the well mouth of the funnel-shaped well body 38 in embodiment 4( Figure 9 ) for use in vegetation restoration weak sections. Further new embodiments can be derived. Since its setting method is also simple, no separate drawing is made here.

[0089] Embodiment 11:

[0090] Figure 23 、 24 This embodiment is another form of improvement based on the seventh embodiment. The mouth of the funnel-shaped sand-blocking well body 61 and the sand-blocking rainwater gutter 52 are movably provided with a water wheel valve 82 (another specific implementation form of the water-activated mouse-proof and mosquito-avoiding valve device) matched therewith to prevent mice and mosquitoes from entering the funnel-shaped sand-blocking groove 63. The water wheel valve 82 is composed of a water falling groove frame 85 matched with the mouth of the funnel-shaped sand-blocking well body 61, a water falling groove 83 provided on the vertical surface of the water falling groove frame 85 and matched with the groove opening of the funnel-shaped sand-blocking groove 63, a water wheel valve shell 86 (like the horizontally placed door wing frame of the energy-saving revolving door) provided at the bottom of the water falling groove 83, a rotating impeller 87 and a wheel shaft 88 provided in the cavity of the water wheel valve shell 86. The upper part of the water wheel valve shell 86 is provided with a water wheel valve inlet 84, and the lower part of the water wheel valve shell 86 is provided with a water wheel valve outlet 89. Since there is no problem of leaf clogging the rainwater gutter in the desert and sand has strong fluidity, the small gap between the rotating impeller 87 and the inner wall of the water wheel valve shell 86, or the narrow water wheel valve inlet and the water wheel valve outlet can all play a role in preventing mice and mosquitoes.

The drawings given are schematic drawings rather than engineering construction drawings. The above embodiments are neither a limitation on the specific embodiments of the present application nor a fixed setting method of the present application. It can be understood that some components or technical features in the above embodiments can be omitted or interchanged or disassembled and reassembled. For example, Figure 13 the well core 48 and / or the groove core 49 and / or the annular water dripping rib 39 can be omitted, and the funnel-shaped well body 46 can be replaced by a straight barrel shape. For example, Figure 15As shown, the funnel-shaped well body 64 and / or the funnel-shaped sand-trapping trough 63 can be changed to a straight cylindrical shape; the well shell 62 and / or the trough shell 65 can be omitted; the funnel-shaped sand-trapping well body 61 can be changed to a cylindrical or square (referring to the cross-section) cylindrical shape, omitting one top-mounted sand-avoiding rainwater inlet pipe or adding several more top-mounted sand-avoiding rainwater inlet pipes. For example, Embodiment 8 ( Figure 17 The curtain valve 68 shown in Example 10 is similar to that in Example 10. Figure 21 The embodiments of the float valve 77 shown in Example 11 can be interchanged. Figure 23 The water turbine valve 82 shown in Example 10 is similar to that in Example 10.

For example, in Example 3... Figure 8 ) and Example 5 ( Figure 11 As shown in the figure, a movable device such as [missing information] can be installed in the well chamber of well body 34. Figure 8 A portable well chamber, matching the shape of the well body 34, is used to collect windblown sand. An overflow outlet is provided on the upper side wall of the well chamber, corresponding to the inner opening of the upper-mounted sand-avoiding rainwater inlet pipe 1.5. And so on, these are all possible, of course. To save resources, especially review resources, the inventors have not exhaustively described all embodiments with similar structures and functions derived from this invention. Therefore, it should be noted that once those skilled in the art understand the basic concept of this invention, they can certainly make several improvements and modifications using the design principles of this invention, and undoubtedly, all of these fall within the protection scope of this invention.
