Problems solved by technology
The device mainly has high requirements on the strength of the root of the guided wave radar, because its price is high and the maintenance cost is increased; in the process of process design, there are certain requirements for details such as reserved holes for civil installation, and at the same time, the device is used in cold winter areas. When in use, the cable freezes due to the fog, which will easily prevent the reflector from moving smoothly on the steel cable. Excessive resistance will increase the damage probability of the instrument and the instrument steel cable.

Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing.
[0018] Such as figure 1 , 4 The shown CWSBR water sail displacement measuring device adopts an ultrasonic sensor 1 installed on the water sail buoy 3, and the ultrasonic sensor 1 adopts a waterproof ultrasonic sensor with a measuring range within the usable range of 0-15 meters and a function of suppressing signal interference, such as figure 2 The ultrasonic cavity wave sensor 1 shown is fixed on the mounting plate 2, one side of the mounting plate 2 is connected with the water sail buoy 3, and the other side of the mounting plate is equipped with 2 sets of pulleys 6, and the guiding steel cable 4 passes through the two sets of pulleys 6, and passes through the The fixed pulley 7 on the pool wall is tightly connected with the spring 8, and the spring end is fixed on the pool wall 10 through the steel cable fixing frame 9. The distance between the two guiding steel cables...

The invention belongs to the field of environmental engineering water treatment and discloses a CWSBR (Constant Waterlevel Sequencing Batch Reactor) water sail displacement measurement device, wherein an ultrasonic sensor is arranged on a water sail buoy and is used for detecting a distance between the water sail buoy and a wall and inputting an ultrasonic signal into a receiving module of a far-end PLC (Programmable Logic Controller). In the invention, the ultrasonic sensor is adopted to replace a guided-wave radar sensor, and is arranged on the water sail buoy and used for measuring the distance between a buoy position (the position of an instrument per se) and the wall in a water sail floating moving process so as to determine the position of a water sail and achieve the purpose of protecting the water sail through program setting. Compared with the traditional scheme, the device disclosed by the invention has the beneficial effects that: the tensile force borne by a steel cable is transferred from the instrument per se in the water sail moving process, and the instrument damage probability is decreased, so that the input cost and the instrument maintenance cost are reduced. An added pulley part can be used for effectively decreasing the resistance of the buoy during moving, and the adverse influence caused by the iced steel cable in winter is decreased.
Description
technical field [0001] The invention belongs to the field of environmental engineering water treatment, in particular to a measuring device for the moving position of a CWSBR water sail. Background technique [0002] The CWSBR? process is a new sewage treatment process improved on the basis of the traditional SBR process. The feature of this process is that the biochemical pool is divided into three areas by its special equipment flexible water sail, and the volume of the three areas becomes The form can be adjusted to achieve the process of intermittent water intake, stirring, aeration, sedimentation and drainage of the SBR process. [0003] The water sail is a special equipment for this process, and it is made of special flexible materials. In the actual operation process, it must be effectively protected to prevent it from being damaged due to the huge tension caused by the water sail moving to the limit position. Therefore, in the project It is necessary to use the meas...
