Technical field
The utility model relates to a kind of environmentally-friendly sanitary protection and PCO device, is mainly used in airtight urban sewerage and drainage, the husky well head of blow-off line, prevents the purpose of " four pests " and anti-foul smell to reach, and belongs to environmentally-friendly sanitary field articles for use.
Background technology
Now the draining blow-off line in city all has husky well head on ground, and husky well head directly connects draining, blow-off line, and husky well head adds and is stamped manhole cover, because manhole cover does not have sealing device, harmful organisms such as mouse, mosquito, cockroach, fly are often from husky well head turnover.Simultaneously, the foul smell of draining blow-off line and Sha Jingzhong also overflows from husky well head, and protection has brought suitable difficulty to urban environmental hygiene.
Summary of the invention
The purpose of this utility model is at prior art weak point in the town and country construction, provide a kind of husky well head of draining, blow-off line that is used for, to prevent " four pests " joint defence of novel environment friendly health and the PCO device of harmful organism such as mouse, mosquito, cockroach, fly and deodorization.
In order to achieve the above object, the utility model is by the following technical solutions:
Novel " four pests " joint defence device comprises that one is provided with down the supporting plate at the mouth of a river, and this time mouth of a river is provided with at least one auto-closing balance gate.
The above-mentioned mouth of a river down is provided with two auto-closing balance gates.
Above-mentioned autobalance Men Weiyi gravity auto-closing balance gate; This gravity auto-closing balance gate comprises and is hinged on the door-plate below the supporting plate and is connected gravity rod with door-plate that described door-plate and gravity rod lay respectively at the both sides of jointed shaft.
Above-mentioned autobalance Men Weiyi elastic force auto-closing balance gate; This state elastic force auto-closing balance gate comprise the door-plate that is hinged on below the jointed shaft and with the coaxial mounted torsionspring of jointed shaft, and this torsionspring one end conflict door-plate, other end conflict supporting plate.
The utility model is simple in structure, adopt the auto-closing balance gate to carry out airtight to draining, the husky well head of blow-off line, can not hinder under the situation of normal draining blowdown, prevent that effectively harmful organisms such as mouse, mosquito, cockroach, fly from often passing in and out, multiply and encroaching on from husky well head, prevent effectively simultaneously that the foul smell that draining, blow-off line and Sha Jingzhong produce from outwards overflowing, thereby improved people's life, dwelling environment.

With the specific embodiment the utility model is further described by the following examples:
The specific embodiment
Embodiment 1
Shown in Fig. 1 to 5, novel " four pests " described in the utility model joint defence device is installed on draining, the husky well head of blow-off line, to prevent mouse, mosquito, cockroach, fly and deodorization.Particularly, it is provided with down the supporting plate 1 at the mouth of a river 2 by one and two auto-closing balance gates 3 being located at down on the mouth of a river 2 are formed.Further, the supporting plate around 2 edges, the following mouth of a river is downward ramped shaped, and it is used to make the drainage guiding, shown in Figure 4 and 5.And described auto-closing balance gate 3 is a gravity auto-closing balance gate, this gravity auto-closing balance gate is made up of door-plate 31, hinge 32 and gravity rod 33, be specially, door-plate 31 is hinged on the supporting plate 1 by hinge 32, and gravity rod 33 is positioned at the jointed shaft opposite side of hinge 32 and fixedlys connected with door-plate 31.Gravity rod 33 and door-plate 31 can be around hinge 32 rotations, because the moment of the torque ratio door-plate 31 of gravity rod 33 is big, under the effect of gravity rod, two door-plates 31 can tend to upwards closed condition, gravity auto-closing balance gate reaches stress balance when door-plate 31 conflicts supporting plate 1 edge at the mouth of a river 2, two door-plates 31 are in closed condition, shown in Fig. 1,3 and 4.
Below by concrete application principle the utility model is further described:
Shown in Figure 4 and 5, on the edge that is installed in draining blow-off line 4 husky well heads by supporting plate of the present utility model, and then add a cover in the above and manhole cover 5 is installed just can have been used.When not having sewage, dirt to enter from the manhole cover mouth, the two fan door-plates of this device are in closed condition under the effect of gravity rod, thereby prevent that harmful organisms such as mouse, mosquito, cockroach, fly from going out and enter from husky well head, prevent that also the foul smell in the blow-off line from overflowing from husky well head.As sewage or dirt when husky well head enters, when the weight of sewage or dirt reaches certain degree (the common moment of sewage or dirt and the relative jointed shaft of door-plate greater than the moment of gravity rod time), two fan door-plates are opened, thereby reach the purpose of draining, blowdown.When the time spent of doing that does not have external gravity, under the effect of gravity rod, two fan door-plates are in closed condition all the time, as shown in Figure 5.
Shown in Fig. 1,2,6 and 7, novel " four pests " described in the utility model joint defence device is installed on the husky well head of draining, blow-off line, and it is provided with down the supporting plate 1 at the mouth of a river 2 by one and two auto-closing balance gates 3 being located at down on the mouth of a river 2 are formed.Further, described auto-closing balance gate 3 is an elastic force auto-closing balance gate, and this elastic force auto-closing balance gate is made up of door-plate 31, hinge 32 and torsionspring 34.Be specially, door-plate 31 is hinged on the supporting plate 1 by hinge 32, torsionspring 34 and the coaxial installation of the jointed shaft of hinge 32, and one end conflict door-plate 31, other end conflict supporting plate 1.Under the effect of torsionspring 34, two door-plates 31 are in closed condition, as shown in Figure 6.Sewage or dirt are being arranged when husky well head enters, when the weight of sewage or dirt reaches certain degree (the common moment of sewage or dirt and the relative jointed shaft of door-plate greater than the spring force of torsionspring time), two fan door-plates are opened, thereby reach the purpose of draining, blowdown, when the time spent of doing that does not have external gravity, under the effect of torsionspring, two fan door-plates are in closed condition all the time, as shown in Figure 7.
Should be noted that, novel " four pests " described in the utility model joint defence device, it is best to be to adopt two auto-closing balance gates, but it also can adopt one or more auto-closing balance gates.Simultaneously supporting plate of the present utility model is can be according to the husky well head shape of practical application different design different matched shape, as rectangle (as illustrated in fig. 1 and 2), infundibulate, circle and square etc.Above-mentioned available embodiment is all in the protection domain of the utility model.
