Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings, and specific embodiments will be given.

As shown in fig. 1 and 2, the workshop discharge port includes an open channel 10, the open channel 10 is rectangular and is provided with a channel for circulating workshop waste water, the upper end of the open channel 10 is open, and when the open channel 10 is installed at a lower position, a worker can directly sample waste water from the opening at the upper end of the open channel 10. The open channel 10 is made of steel, and can be integrally formed by bending a steel plate during specific processing, or formed by welding a plurality of steel plates in a seamless manner.

The two sides of the open channel 10 are respectively provided with a water inlet 11 and a water outlet 12 which are communicated with the channel, the channel is internally provided with a water inlet section 2, a connecting section 3, a measuring section 7 and a water outlet section 5 which are sequentially communicated along the direction from the water inlet 11 to the water outlet 12, the water inlet section 2 is provided with a still water well 9, and the length and the width of the inner wall of the still water well 9 are equal to the width of the channel of the open channel 10. The lower extreme of stilling well 9 is less than the lower extreme of linkage segment 3, water inlet 11 and stilling well 9 intercommunication, and the upper end of water inlet 11 and the lower extreme parallel and level of linkage segment 3, the degree of depth of stilling well 9 is greater than the internal diameter of water inlet 11, the lower extreme position height of stilling well 9 is less than the lower extreme of water inlet 11 promptly, in actual processing, the lower extreme of stilling well 9 is less than about 50mm of water inlet 11 lower extreme can, the setting of stilling well 9 lower extreme is less than water inlet 11 and linkage segment 3, it is sunken form to be the stilling well 9 lower extreme promptly, form the water retaining bay, waste water is after discharging through open channel 10, when open channel 10 no longer crosses water, this department can leave certain deposit water sample detection to this department in 24 hours after waste water discharges.

The length of the connecting section 3 is greater than 5 times the channel width of the open channel 10 so that the flow of wastewater has a sufficiently flat section in the connecting section 3 to allow stable flow of water into the marshall tank 4.

The measurement section 7 is internally provided with the Parshall tank 4, the Parshall tank 4 is the Parshall tank 4 in the prior art, the Parshall tank 4 is arranged in the measurement section 7, when the measurement section is fixed, according to the material (generally, the material of the glass fiber reinforced plastics) of the Parshall tank 4, the glass fiber reinforced plastics can be lined in the open channel 10, and then the Parshall tank 4 is directly bonded in the measurement section 7, so that the installation is simple and convenient. The distance is arranged between the water outlet end of the Parshall tank 4 and the water outlet section 5, and during actual processing, the distance of about 50mm can be set, and through the arrangement of the distance, the wastewater can be buffered after passing through the Parshall tank 4, so that the influence of the water dropping immediately after the wastewater leaves the Parshall tank 4 on the water flow state in the Parshall tank 4 is avoided.

The water outlet 12 is communicated with the water outlet section 5, and the lower end of the water outlet 12 is lower than the lower end of the water inlet 11, so that a certain water level difference is ensured between inlet water and outlet water, the outlet water of wastewater is smooth, and the lower end of the water outlet 12 is flush with the lower end of the water outlet section 5, so that the wastewater can be completely discharged through the water outlet 12. The internal diameter of delivery port 12 is greater than the internal diameter of water inlet 11, and is concrete, and water inlet 11 communicates

inlet tube

1, and 1 internal diameter of inlet tube equals 11 internal diameters of water inlet, and delivery port 12 communicates

outlet pipe

6, and 6 internal diameters of outlet pipe equal to 12 internal diameters of delivery port, and inlet tube 1, outlet pipe 6 all select standard system pipe fitting for use, and the pipe diameter of outlet pipe 6 compares the pipe diameter of inlet tube 1 and needs enlargies two numbers, and delivery port 12 internal diameter sets up great, avoids the harmony water, guarantees to go out.

The intercommunication has sampling pipe 8 on outlet pipe 6, and when open channel 10 mounted position was higher, sampling pipe 8 can set up longer to the staff samples through sampling pipe 8.

Workshop waste water passes through in water inlet 11 gets into still water well 9, the upper end of water inlet 11 and the upper end parallel and level of linkage segment 3, therefore the unable direct access linkage segment 3 of waste water, and waste water receives the fender effect that returns of still water well 9 lateral walls, and the flow direction changes, and then reduces the kinetic energy of intaking for the rivers that workshop waste water got into in the linkage segment 3 are more steady. The workshop wastewater flows straightly to the measuring section 7 in the connecting section 3, and the water flow stably enters the Parshall tank 4 to measure the wastewater flow. The waste water enters the water outlet section 5 and is discharged through the water outlet 12.

In another embodiment of the present invention, as shown in fig. 3, a telescopic bracket is installed on the outer wall of the open channel 10, when the open channel 10 is installed in a workshop, the installation height of the open channel 10 is adjusted by the telescopic bracket, and the telescopic bracket can be a conventional bracket which has a telescopic function and can support the open channel 10. In this embodiment, telescopic bracket includes backup pad 15, fixed connection is at backup pad 15 a plurality of telescopic leg 14 all around and fix at the brace table 13 of telescopic leg 14 lower extreme, telescopic leg 14 optional electric telescopic handle, backup pad 15 upper end is equipped with the mounting groove that supplies open channel 10 card to go into, when the installation, open channel 10 card is in the mounting groove, place on telescopic bracket, can be comparatively convenient regulation open channel 10's mounting height through telescopic bracket, in some workshops, open channel 10 also can be followed telescopic bracket and taken off, directly place and install on the workshop subaerial.

The utility model discloses a further embodiment, sampling pipe 8 can be dismantled and connect on outlet pipe 6, and sampling pipe 8 is close to the one end of outlet pipe 6 and is fixed with the screen cloth, and in this embodiment, 8 threaded connection of sampling pipe are on outlet pipe 6, through the setting of screen cloth, avoid impurity in the waste water to get into sampling pipe 8 in, regularly dismantle sampling pipe 8 and can clear up the screen cloth.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
