Problems solved by technology

But for civil buildings, the trickle is usually the main body, so ignoring the measurement of the trickle is inaccurate and incomplete data, which cannot be used for experiments and research, as well as the basis for decision
Another problem in measuring sewage is that most of the traditional water flow metering equipment are designed for clear water or water flow with relatively uniform impurities. However, there are a large number

Example Embodiment

[0017] Example one:

[0018] This embodiment is an intermittent flow monitoring equipment, including: a water inlet pipe 1, a measuring box 2 installed below the water inlet pipe, a drain pipe 7 is arranged on the bottom side of the measuring box, and a tipping bucket is arranged in the measuring box. The tipping bucket includes a container 4 for receiving the liquid flowing out of the water inlet pipe and a hinge 5 connecting the container with the measuring box. The empty center of mass 402 of the container is located at one side of the hinge, and the empty center of mass keeps the container horizontal. The full-filled center of mass 401 in the fully-filled state of the container is located on the other side of the hinge, and the full-filled center of mass makes the tipping bucket tilt and flip, and the tipping bucket also includes a counter 6 that records the number of tilt and flips of the container, such as figure 1 Shown.

[0019] The working principle of this embodiment is: ...

Example Embodiment

[0033] Embodiment two:

[0034] This embodiment is an improvement of the first embodiment, and is a refinement of the hinge in the first embodiment. The hinge described in this embodiment is arranged at the bottom of the container.

[0035] The location of the hinge installation on the container is very important, and it is the key to whether the container can be flipped correctly and restored to balance. In this embodiment, the hinge is installed on the bottom of the container. In this case, relying on the weight of the container itself, there is no help of any balancing device when the container is empty, except for some special positions, which can keep the container in a horizontal equilibrium position. Therefore, in order to maintain balance when the container is empty, a balancer needs to be installed at a certain position.

Example Embodiment

[0036] Example three:

[0037] This embodiment is an improvement of the second embodiment, and is a refinement of the second embodiment regarding the balancer. The measuring box described in this embodiment is also provided with a balancer 3.

[0038] There are many options for the balancer. A balance block can be set on the side wall of the measuring box, so that one side of the container leans against the side wall of the measuring box to maintain balance. It is also possible to set up a stand in the measuring box to hold up the container and maintain balance.

Abstract

The invention relates to monitoring equipment of intermittent flows. The monitoring equipment comprises a water inlet pipe, a measuring tank and a draining pipe. A tipping bucket is disposed in the measuring tank. The tipping bucket comprises a container for receiving liquid flowing out of the water inlet pipe and a hinge connecting the container with the measuring tank. The empty mass center of the empty container is located on one side of the hinge. The empty mass center allows the container to keep horizontal. The full mass center of the full container is located on the other side of the hinge. The full mass center allows the tipping bucket to incline and turn over. The tipping bucket further comprises a counter for recording the inclining and turning over times of the container. The monitoring equipment has the advantages that tipping bucket measuring is used, intermittent flow measuring which cannot be continuously performed is changed into measuring of the inclining and turning over times of the tipping bucket, and precise sewage measuring is achieved; the measuring of the inclining and turning over times of the tipping bucket can be easily digitalized, so that sewage amount calculation is quite convenient and accurate; due to the fact that the tipping bucket is of a quite simple mechanical structure, fault probability is reduced, and the problem of impurity blocking can be well avoided.

Description

technical field [0001] The invention relates to a monitoring device for intermittent flow, which is a metering device, and is an instrument suitable for monitoring the discharge of sewage in drainage pipes of buildings in the field of urban water circulation. Background technique [0002] In recent years, urban water consumption has shown a trend of high intensity and rapid growth. The intuitive definition of water consumption is: the difference between water supply (including local precipitation) and drainage. In the process of quantitative calculation of displacement, especially in the field of urban water cycle to monitor the discharge of sewage in drainage pipes in various buildings (residential, office, shopping malls, factories, etc.), traditional flow measuring instruments (such as water meters) ) cannot meet the monitoring of intermittent flow in water pipes. The sewage drainage flow in the building is a very unstable water flow, and it is a kind of intermittent wat...
