The utility model relates to an unpowered opening and closing odor-resistant sundry-resistant gutter inlet, which has the following working period that: standby time, operation preparation time, operation time, and standby preparation time.

The unpowered open-close odor-resistant sundry-proof gutter inlet provided by the utility model is in a non-rainfall period during standby. At the moment, the rainwater collection well (1) of the rainwater automatic control opening and closing deodorization sundry-preventing rainwater inlet has no water inside, the external pressure of pistons at two ends of a hydraulic control system (5) related to the rainwater collection well (1) and the rainwater well (6) is equal to the atmospheric pressure, a certain height difference is formed between the upper edges of a power piston (12) and a working piston (13), and a deodorization sundry-preventing device (10) just covers the rainwater well (6) and the lower edge of a rainwater grate (7) to play roles of preventing odor from emitting and preventing external sundries from falling.

The unpowered open-close odor-resistant sundry-proof gutter inlet provided by the utility model is prepared during the beginning period of rainfall. At the moment, as the rainwater grate (7) is sealed by the deodorization and sundry prevention device (10), when runoff is generated on the ground, rainwater in a corresponding catchment area converges to the position near a rainwater automatic control opening and closing deodorization and sundry prevention rainwater port, the rainwater can firstly flow into the rainwater collection well (1) through the rainwater collection port (2), and the bottom of the rainwater collection well (1) and the side wall of the upper edge of the power piston (13) are connected with the drain pipe (3). In the time period of low rainfall intensity and small ground runoff, the rainwater amount flowing into the rainwater collecting well (1) is less than or equal to the drainage amount of the drain pipe (3), and at the moment, the rainwater is directly drained into the rainwater well (6) from the drain pipe (3) after being blocked by the grating (12). With the continuous increase of rainfall intensity, the ground runoff is also gradually increased, when the rainwater amount flowing into the rainwater collection well (1) is larger than the drainage amount of the drain pipe (3), redundant rainwater starts to collect in the rainwater collection well (1), the water level gradually rises, the mass of the rainwater in the well is continuously increased, and the gravity of the rainwater acting on the power piston (13) is also increased. According to the Pascal law, the balance of forces on two sides of the hydraulic control system (5) is broken when in standby; the power piston (13) is caused to descend because of continuously receiving the continuously increased gravity from the water in the rainwater collection well (1), rainwater in the rainwater collection well (1) does work on the working piston (14), the working piston (14) pushes the deodorization and sundry prevention device (10) to leave the upper part of the rainwater well (6) under the action of force and enter the protection plate (9), and the upper part of the rainwater well (6) is unsealed. At this time, the preparation time ends, the working time starts, and the drainage of rainwater on the ground starts.

The unpowered open-close odor-resistant sundry-proof gutter inlet provided by the utility model is operated in a rainfall process period. Due to the continuity of rainfall and the unpowered control opening and closing stinking-proof sundries-proof rainwater inlet setting point which is the lowest point in the corresponding catchment area, even when the rainwater collector works, rainwater can continuously flow into the rainwater collection well (1) through the rainwater collection port (2); at the moment, the rainwater amount of the rainwater collecting well (1) is larger than the drainage amount of the drain pipe (3), the water level in the rainwater collecting well (1) gradually rises until the rainwater fills the rainwater collecting well (1), so that the gravity of the rainwater acting on the power piston (13) is kept constant, the constant force with basically unchanged magnitude is acted on the working piston (14) through the hydraulic control system (5), and the constant force is transmitted to the deodorization and sundry prevention device (10) by the working piston (14) to be stably fixed in the protection plate (9). Therefore, the possibility of mistakenly closing the deodorization sundries-preventing device (11) can not occur during the work.

The unpowered open-close odor-resistant sundry-proof gutter inlet provided by the utility model is prepared in a standby mode and occurs in a rainfall ending period. After the rainfall is finished, the ground runoff is slowly finished, no ground rainwater flows into the rainwater collecting well (1), rainwater in the rainwater collecting well (1) slowly flows into the rainwater well (6) through the drain pipe (3) at the moment, the water level in the rainwater collecting well (1) continuously descends, the rainwater amount acting on the power piston (13) is gradually reduced, and the gravity descends. According to the Pascal law and the force balance principle, the external force of the power piston (13) disappears gradually, so that the power piston (13) can rise slowly, the power piston (13) returns to the original position until rainwater in the rainwater collection well (1) is drained completely, the working piston (14) is connected to return to the original position, the deodorization sundries prevention device (10) is dragged to leave the protection plate (9), and finally the deodorization sundries prevention device is covered on the rainwater well (6) and below the rainwater grate (7) completely to play roles of preventing odor from diffusing and preventing external sundries from falling into the rainwater collection well again. Therefore, the gutter inlet of the utility model finishes standby preparation and starts standby.

The utility model relates to an unpowered opening and closing odor-resistant sundry-resistant rainwater inlet, which is characterized in that a rainwater collecting well (1), a water drain pipe (3) and a hydraulic control system (5) are the technical core of the utility model. The rain collecting well (1) and the water drain pipe (3) automatically control the four working states of the gutter inlet to alternately operate by utilizing the basic fluid mechanics principle and the characteristics of dynamic change and balance of collected water quantity. The basic principle of the hydraulic control system (5) is the Pascal law, the characteristic that the pressures of pistons on two sides of a hydraulic oil cylinder (16) are equal is utilized, and the power piston (13) and the working piston (14) are designed to have different areas and different masses, so that the two sides of the piston have a certain height difference during standby balance, and the stress balance of the normal operation of the hydraulic control system is met. In addition, the volume of the rain collecting well (1) plays a role of safe buffer volume, namely if someone tries to open the deodorization and sundries prevention device (10) to dump garbage in sunny days, enough water must be dumped into the rain collecting port (2), the dumped water volume is continuous and larger than the drainage volume of the drain pipe (3), and general people cannot obtain corresponding water sources nearby; in terms of actual life, in order to dump garbage once, a large amount of water is firstly poured into the rain collecting well (1) to open the deodorization and sundry prevention device (10) in a linkage manner, which is inconvenient.

The unpowered open-close odor-resistant sundry-resistant gutter inlet has the beneficial effects that: the whole system has simple principle, no complex mechanical structure and convenient production and construction; the alternating operation of the unpowered rainwater drainage working condition and the deodorization and sundry falling prevention working condition is realized without human participation; the rainwater safety drainage in rainy days is guaranteed, the health of residents is guaranteed, and the service efficiency of the rainwater inlet is improved; the core design idea of the rain collecting well (1) effectively prevents people from maliciously irrigating water and conspiring to open the deodorization and sundry-prevention device (10) to dump garbage.
