[0002] Bridge deck runoff treatment mostly adopts the mode of "double pipeline", which is composed of two pipelines arranged side by side, and is respectively a pipeline special for dangerous chemicals and a bridge deck runoff collecting pipeline. The pipeline special for dangerous chemicals penetrates through the whole bridge, while the bridge deck runoff collecting pipeline is arranged in groups and in sections as "independent drainage units", and is connected in communication with the pipeline special for dangerous chemicals through a "U-shaped siphon pipe".
[0003] However, the above prior art can meet the shunting function required by the double pipeline. But when the precipitation stops, a part of the rainwater in the normal drainage pipe cannot be emptied. In addition, the bridge deck runoff collecting pipeline is a water conveying channel, and the sealing is an important link to ensure the normal operation of the system. The inverted "U"-shaped overflow device is made by combining PVC elbow pipes, three-way pipes and straight pipes in multiple sections and adjusting the positions, and then bonding with PVC glue. The device is not easy to manufacture and is inconvenient to construct, and the quality of the device cannot be guaranteed. During construction, the pipelines are pulled and twisted with each other, the PVC bonding is slightly cracked, and finally the pipeline splicing part leaks. CONTENT OF THE UTILITY MODEL

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. EMBODIMENT
[0022] Please refer to Figs. 1-3 The utility model provides the following technical scheme: to achieve the above object, the utility model provides the following technical scheme: a siphon type liquid distributor, including shell 7, liquid inlet 1, liquid outlet 6 and siphon 3 arranged on shell 7, part of siphon 3 extends into the shell, the shell 7 is equipped with partition 8, the lower part of partition 8 is equipped with water inlet hole, liquid inlet 1 and liquid outlet 6 are located on the same side of partition 8, the liquid inlet end of siphon 3 is located on the other side of the partition 8, and a gap is left between partition 8 and the part of siphon 3 extending into the shell, and a gap is formed between the liquid inlet end of siphon 3 and the top wall of shell 7 to form a siphon cavity.
[0023] In use, the siphon type liquid distributor is installed to the bridge surface runoff collection pipe 14 way connection unit, and specifically, the bridge surface runoff collection pipe 14 way connection unit includes the siphon type liquid distributor, control valve 13, collection pipe 14 and hazardous chemical special pipe 15, the collection pipe 14 is connected with the liquid inlet 1 of the siphon type liquid distributor, the hazardous chemical special pipe 15 is connected with the siphon 3 of the siphon type liquid distributor, and the control valve 13 is connected with the liquid outlet 6 of the siphon type liquid distributor for directly placing non-chemical goods. Further, in order to successfully empty the liquid in the collection pipe 14, the height of the liquid inlet end of the siphon is preferably between 50% and 80% of the fullness of the collection pipe. Further, in order to conveniently adjust the height of the liquid inlet end of the siphon 3, an adjusting structure for adjusting and limiting the length of the siphon 3 extending into the shell 7 is arranged between the siphon 3 and the shell 7, for example, the adjusting structure can be a sealing screw thread structure, as long as the two parts can be fixedly connected together after being adjusted.
[0024] When it is raining and there is no dangerous chemical, the bridge runoff is discharged through the collecting pipe 14, the liquid in the collecting pipe 14 is detected to be free of dangerous chemicals, the control valve 13 receives an opening signal, and thus the liquid in the collecting pipe 14 is discharged through the liquid inlet 1, the liquid outlet 6 and the control valve 13 on the shell 7 in sequence, so as to achieve the effect of direct discharge of the rainwater collected from the bridge into the subsequent treatment system.
[0025] Further, in order to enhance the above-mentioned direct discharge effect, the liquid inlet 1 and the liquid outlet 6 are preferably arranged oppositely to reduce the residence time and resistance in the liquid siphon distributor. When it is raining heavily, in order to ensure that the water on the bridge can be quickly collected into the pipeline of the collecting and treatment system to reduce the influence of the water on the bridge on traffic safety, when the discharge capacity of the control valve 13 is insufficient, the liquid can enter the side of the baffle 8 close to the siphon pipe 3 through the water inlet hole in the lower part of the baffle 8, since there is a gap between the baffle 8 and the part of the siphon pipe 3 extending into the shell, and there is a gap between the liquid inlet end of the siphon pipe 3 and the top wall of the shell 7, the liquid is continuously collected in the box until the liquid level is higher than the liquid inlet end of the siphon pipe 3, at this time, the liquid enters the siphon pipe 3 to form a siphon effect, and a part of the liquid is discharged through the dangerous chemical special pipe 15 connected with the siphon pipe 3, which greatly relieves the pressure of the liquid in the collecting pipe 14 discharged through the control valve 13, and can greatly solve the problem of water on the bridge. It should be noted that the pipeline connection unit scheme protected by the utility model is not within the scope of the scheme claimed by the utility model, whether the liquid of the bridge runoff contains chemicals or the treatment of the rainwater collected after being free of dangerous chemicals and the treatment of the collected liquid containing dangerous chemicals are mature technologies, and thus will not be described herein.
[0026] When the liquid of the bridge runoff contains dangerous chemicals, the liquid in the collecting pipe 14 is detected to contain dangerous chemicals, the control valve 13 receives a closing signal, and the liquid containing dangerous chemicals is directly discharged through the collecting pipe 14, the liquid inlet 1 of the siphon distributor, the water inlet hole in the baffle 8, the gap between the baffle 8 and the part of the siphon pipe 3 extending into the shell, the gap between the liquid inlet end of the siphon pipe 3 and the top wall of the shell 7, the siphon pipe 3 and finally forms a siphon effect to enter the dangerous chemical special pipe 15 for subsequent treatment.
[0027] Preferably, the siphon pipe 3 is provided with a step 4, and the step 4 is arranged close to the liquid outlet end of the siphon pipe 3. In order to connect stably, the step 4 is designed at the liquid outlet end of the siphon pipe 3, which is connected with the dangerous chemical special pipe 15 to play a limiting role and facilitate the addition of a sealing ring at the position to prevent leakage. In rainy weather, the harmfulness of the bridge runoff is not large, but the road surface leakage and tree leaves will cause the equipment to work normally, and thus the inventor sets the water inlet hole in the filter 9.
[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
