[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1-4As shown, this utility model provides a technical solution: an automatic pH value measuring and transmission device for wastewater from a concrete mixing plant, including a fixed box 1, a signal transmitter 2 fixedly installed at one end inside the fixed box 1, and a rapid detection and cleaning mechanism 3 fixedly installed at the end inside the fixed box 1 away from the signal transmitter 2.

[0030] The rapid detection and cleaning mechanism 3 includes an electric telescopic rod 301, a lifting frame 302, a pH meter 303, a detection electrode 304, a mounting bracket 305, an inclined liquid distribution box 306, an infusion tube 307, a connecting pipe 308, and an infusion pump 309.

[0031] An electric telescopic rod 301 is symmetrically fixedly installed inside the fixed box 1 at the end away from the signal transmitter 2. A lifting frame 302 is fixedly connected between the bottom ends of the two electric telescopic rods 301. A pH meter 303 is fixedly installed in the middle of the lifting frame 302. Detection electrodes 304 are symmetrically installed at the bottom of the pH meter 303. The signal output end of the pH meter 303 is connected to the signal input end of the signal transmitter 2. Both detection electrodes 304 movably pass through the bottom of the lifting frame 302. The two detection electrodes 304 are a glass electrode and a reference electrode, respectively.

[0032] A mounting bracket 305 is fixedly installed at the bottom of one end of the fixed box 1. An inclined liquid distribution box 306 is symmetrically fixedly installed in the middle of the mounting bracket 305. The two inclined liquid distribution boxes 306 are symmetrically distributed on both sides of the lifting frame 302. Water spray holes are equidistantly opened at both ends of the inclined surfaces of the two inclined liquid distribution boxes 306, and the water spray holes face the two detection electrodes 304. An infusion tube 307 is fixedly connected to the middle of each of the two inclined liquid distribution boxes 306. A connecting pipe 308 is fixedly connected between the ends of the two infusion tubes 307. An infusion pump 309 is fixedly installed at one end of the bottom of the fixed box 1. A water delivery pipe is fixedly connected to both the inlet and outlet ends of the infusion pump 309. One of the water delivery pipes is connected to the middle of the connecting pipe 308. The system connects to another water supply pipe, which is connected to an external water supply pipe. The height of the pH meter 303 is adjusted using an electric telescopic rod 301 and a lifting frame 302, allowing the detection electrode 304 to be quickly inserted into the wastewater for testing. After testing, the electrode can be smoothly lifted away from the wastewater. The operation and control method is simple. At the same time, the infusion pump 309 can inject cleaning water into the two inclined liquid distribution tanks 306 and spray it at an angle onto the surface of the two detection electrodes 304, which can rinse and clean the detection electrodes 304. This prevents wastewater and impurities from adhering to the surface of the detection electrodes 304 for a long time and affecting subsequent testing. Timely cleaning can keep the detection electrodes 304 clean at all times, eliminating the need for subsequent manual cleaning and maintenance.

[0033] The fixed box 1 is equipped with a convenient control mechanism 4;

[0034] The convenient control mechanism 4 includes a laser emitter 401, a connecting plate 402, a laser receiver 403, and a delayer 404;

[0035] A laser emitter 401 is fixedly installed at the top center of the lifting frame 302. A connecting plate 402 is fixedly installed at the bottom center of the fixed box 1. A laser receiver 403 is fixedly installed at the top center of the connecting plate 402. A timer 404 is fixedly installed at the top of the connecting plate 402 on one side of the laser receiver 403. The laser emitter 401 and the laser receiver 403 are located on the same vertical plane. The signal input and output terminals of the timer 404 are connected to the signal output terminal of the laser receiver 403 and the signal input terminal of the infusion pump 309, respectively. By using the cooperation of the laser emitter 401 and the laser receiver 403, the lifting position of the pH meter 303 is determined, and the information of the descent is captured to control the infusion pump 309 to start for flushing and cleaning. The timer 404 delays the control time, and the delay time is the detection time of the pH meter 303. This ensures that the infusion pump 309 will only deliver water for flushing during the ascent after the pH meter 303 has completed its descent detection. This makes the control more precise and convenient.

[0036] The working principle and usage process of this utility model are as follows: First, the fixed box 1 is fixedly installed at the corresponding position of the wastewater discharge pool of the concrete mixing plant, so that the pH meter 303 and the detection electrode 304 are both located above the wastewater pool. During the operation and production of the concrete mixing plant, a large amount of wastewater is generated. Before discharge, the pH value of the wastewater needs to be tested regularly to prevent the pH value of the wastewater from exceeding the standard. The staff can remotely control the measurement process by remotely starting the electric telescopic rod 301, which extends downward and pushes the lifting frame 302 and the pH meter 303 down. The laser emitter 401 descends synchronously and emits a laser beam. When the lifting frame 302 descends to a certain height, the laser emitter 401 and the laser receiver 403 are positioned to correspond to each other, so that the emitted laser is captured by the laser receiver 403 and the signal is transmitted to the delay timer 404. The lifting frame 302 continues to descend until the detection electrode 304 is inserted into the wastewater.

[0037] The two detection electrodes 304 are a glass electrode and a reference electrode, respectively, which can be used to detect the pH value of wastewater. The pH meter 303 will analyze the measured data and transmit it to the signal transmitter 2, which will then transmit it remotely so that staff can understand the information of the discharged wastewater in a timely manner.

[0038] After a period of time, the measurement ends, the electric telescopic rod 301 retracts upward, pulling the lifting frame 302 and pH meter 303 upward. The signal received by the delay device 404 will be transmitted to control the infusion pump 309 after a period of time, the time matching the measurement time. After the measurement ends, the pH meter 303 rises to a certain level, and the infusion pump 309 is started, injecting water supplied from the outside into the inclined liquid distribution box 306 through the connecting pipe 308 and the infusion pipe 307. The water is then sprayed obliquely from the two inclined liquid distribution boxes 306 onto the surface of the two detection electrodes 304, rinsing them during the rising process and removing wastewater impurities adhering to the surface of the detection electrodes 304, keeping the detection electrodes 304 clean.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
