Abstract

The utility model relates to a four-proof device, which comprises a shell, the upper part of the shell is a water collecting port, the four sides of the water collecting port are provided with seat stops, the middle part of the shell is a water collecting tank, and the bottom of the shell is provided with a drain port , A one-way gate is arranged on the upper part of the drain, and the gate shaft of the gate is connected with the shaft seat on the shell. The utility model collects rainwater through the water collection tank. When there is a lot of rainwater, the gate of the one-way gate is opened by the weight of the water to discharge from the drain. Closing the drain, the drain is tightly closed, blocks the passage to the outside, can prevent mosquitoes, cockroaches, rats, and deodorize, and effectively improve people's living environment.

Description

Four proofings apparatus

[technical field]

The utility model relate to a kind ofly be applicable on sewer or the irrigation canals and ditches, can mosquito-proof, anti-cockroach, anti-mouse and deodorization and take the Four proofings apparatus of unidirectional gate.

[background technology]

Sewer in the city, cloudy smelly place such as irrigation canals and ditches grows mosquito especially easily, and the breeding cockroach is concealed mouse and distributes foul smell.This problem is perplexing people always, in order to improve dwelling environment, build civilization, health, beautiful home, people try every possible means and take various means, dropped into great amount of manpower and material resources, come killing mosquito, mouse and health improvement work, but effect is all unsatisfactory, and even to this day, people are also making great efforts for this reason.

[utility model content]

In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of and is applicable on sewer or the irrigation canals and ditches, can mosquito-proof, anti-cockroach, anti-mouse and deodorization and take the Four proofings apparatus of unidirectional gate.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of Four proofings apparatus, comprise housing, described housing top is inlet, four limits of this inlet are provided with the bearing seam, the housing middle part is a catch basin, the bottom of housing is provided with outfall, is provided with unidirectional gate on outfall top, and the door-hinge of this gate and the axle bed on the housing join.

The area of described inlet is preferably 4: 1 with the ratio of the area of outfall.

The flashboard of described unidirectional gate and the bottom surface of housing form angle, and this angle is an acute angle.

Described catch basin is a cone-shaped.

The beneficial effects of the utility model are: collect rainwater by catch basin, when rainwater for a long time, the gate that unidirectional lock is opened in the deadweight of dependence water discharges from outfall, when not having rainwater,, make flashboard close outfall because unidirectional flashboard and housing bottom surface are acute angle, outfall closes, block passage outward, can play the effect of mosquito-proof, anti-cockroach, protection against rodents, deodorization, improved people's dwelling environment effectively.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a longitudinal sectional view of the present utility model

Among the figure: 1-housing, 2-inlet, 3-outfall, 4-bearing seam, the unidirectional gate of 5-, 51-door-hinge, 6-catch basin.

[specific embodiment]

Referring to Fig. 1 and Fig. 2, a kind of Four proofings apparatus comprises housing 1, described housing 1 top is inlet 2, four limits of this inlet 2 are provided with bearing seam 4, and housing 1 middle part is a catch basin 6, and this catch basin 6 is a cone-shaped, collect rainwater by this catch basin 6, the bottom of housing 1 is provided with outfall 3, is provided with unidirectional gate 5 on outfall 3 tops, and the door-hinge 51 of this unidirectional gate 5 is coupling with the axle bed on the housing 1, rely on the deadweight of water to open unidirectional gate 5, rainwater discharges from outfall 3.

The area of the utility model inlet 2 is preferably 4: 1 with the ratio of the area of outfall 3, and the bottom surface of the flashboard of unidirectional gate 5 and housing 1 formation angle, and this angle is an acute angle; When not having rainwater, because unidirectional gate 5 is an acute angle with housing 1 bottom surface, make flashboard close outfall, outfall 3 closes, and has blocked passage outward, can play the effect of mosquito-proof, anti-cockroach, protection against rodents, deodorization, improves people's dwelling environment effectively.
