Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and more specifically, to a water quality testing device for municipal water supply pipelines. Background Technology

[0002] The safety of drinking water is a matter of concern to every household, and ensuring drinking water safety is of utmost urgency. The laying of water supply pipelines is long and complex, and drinking water needs to be transported over long distances and for long periods of time to reach users. During the transportation process, drinking water is easily polluted and its quality deteriorates due to various physical, chemical, and microbial effects. Therefore, it is essential to monitor and issue early warnings for water quality at key points in the water supply network in real time.

[0003] Patent document CN213236705U discloses a water quality testing device for municipal water supply pipelines, comprising a main body. Drive wheels are fixedly connected to the four lower corners of the main body. An L-shaped support plate is fixedly connected to the upper rear of the main body. Protective baffles are fixedly connected to the upper left and upper right of the main body. A telescopic controller is fixedly connected to the upper rear end of the L-shaped support plate. The output end of the telescopic controller passes through the L-shaped support plate and is fixedly connected to a telescopic structure. A rotating structure is installed inside the telescopic structure. A detection structure is fixedly connected to the lower end of the telescopic structure. This utility model's water quality testing device for municipal water supply pipelines, by incorporating the telescopic, rotating, and detection structures, increases the convenience of storage when the device is not in use. The rotating and detection structures increase the detection range and area during testing, and also increase the flexibility of the device during use.

[0004] However, in existing detection devices, the detection head is easily damaged by accidentally contacting the inner wall of the pipe when it is inserted into the pipeline. Once the detection head is damaged, it will not only directly affect the accuracy of water quality test data, but also lead to increased equipment maintenance costs, interruption of the testing process, and thus reduce overall work efficiency. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a water quality testing device for municipal water supply pipelines, which can center the testing head inside the pipeline, reduce the probability of the testing head touching the inner wall of the pipeline, protect the testing head, and ensure working efficiency.

[0006] A municipal water supply pipeline water quality testing device includes a frame, on which a first electric telescopic rod is mounted. An installation cylinder is fixedly connected to the telescopic end of the first electric telescopic rod. A positioning mechanism is provided inside the installation cylinder, which is used to center the installation cylinder and enter the municipal pipeline. A connecting frame is fixedly connected to the lower end face of the installation cylinder, and a testing head is mounted on the connecting frame.

[0007] Furthermore, the positioning mechanism includes two connecting members that slide through the mounting cylinder, and each of the two connecting members has a rolling wheel installed at one end that is far apart from each other. A second electric telescopic rod is fixedly installed inside the mounting cylinder, and a mounting block is fixedly connected to the telescopic end of the second electric telescopic rod.

[0008] Furthermore, the two connecting members are provided with a slope on the side that is close to each other.

[0009] Furthermore, a spring is fixed between the two connecting parts.

[0010] Furthermore, the frame is equipped with casters.

[0011] Furthermore, a handrail is fixedly attached to the frame.

[0012] Furthermore, a positioning ring is fixedly connected to the frame.

[0013] Furthermore, the mounting cylinder passes through the positioning ring.

[0014] Furthermore, the connecting frame includes a fixing rod fixed to the lower end face of the mounting cylinder, and a plurality of connecting rods are fixed to the peripheral side wall of the fixing rod.

[0015] Furthermore, the detection head is fixedly installed at the end of the connecting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the extension of the second electric telescopic rod causes the mounting block to contact the inclined surface, pushing the two connecting parts away from each other. This, combined with the extension of the first electric telescopic rod, causes the rolling wheel to contact the inner wall of the municipal pipeline. During the process of adjusting the mounting cylinder to be centered within the municipal pipeline by the positioning mechanism, and in conjunction with the movement of the vehicle frame, once the mounting cylinder is centered within the municipal pipeline, the detection head can then perform normal water quality testing in conjunction with the extension of the second electric telescopic rod. By setting up a positioning mechanism, the detection head is positioned centered within the pipeline, reducing the probability of the detection head touching the inner wall of the municipal pipeline, protecting the detection head, and ensuring work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0025] like Figure 1-3 As shown, a municipal water supply pipeline water quality testing device includes a frame 1, on which a first electric telescopic rod 2 is mounted. The telescopic end of the first electric telescopic rod 2 is fixedly connected to an installation cylinder 3. A positioning mechanism 4 is provided inside the installation cylinder 3. The positioning mechanism 4 is used to center the installation cylinder 3 into the municipal pipeline 5. A connecting frame 6 is fixedly connected to the lower end face of the installation cylinder 3. A detection head 7 is mounted on the connecting frame 6 for water quality testing. The detection head 7 is connected to an external display and controller (not shown in the figure, which is conventional prior art and will not be described in detail here).

[0026] like Figure 1-3As shown, the positioning mechanism 4 includes two connecting members 41 that slide through the mounting cylinder 3. Rolling wheels 42 are installed at the ends of the two connecting members 41 that are far apart from each other. The rolling wheels 42 roll against the inner wall of the municipal pipeline 5. A second electric telescopic rod 43 is fixedly installed inside the mounting cylinder 3. An mounting block 44 is fixedly connected to the telescopic end of the second electric telescopic rod 43. An inclined surface 45 is provided on the side of the connecting members 41 that is close to each other. The extension of the second electric telescopic rod 43 causes the mounting block 44 to contact the inclined surface 45, thus pushing the two connecting members 41. 1. When the two poles move away from each other, the first electric telescopic rod 2 extends, causing the rolling wheel 42 to contact the inner wall of the municipal pipeline 5. During the process of adjusting the installation cylinder 3 to be centered inside the municipal pipeline 5, the positioning mechanism 4 moves the frame 1. After the installation cylinder 3 is centered inside the municipal pipeline 5, the detection head can cooperate with the extension of the second electric telescopic rod 43 to carry out water quality testing normally. By setting the positioning mechanism 4, the position of the detection head 7 is centered inside the pipeline, reducing the probability of the detection head 7 touching the inner wall of the municipal pipeline 5, protecting the detection head 7, and ensuring work efficiency.

[0027] like Figure 1-3 As shown, a spring 46 is connected between the two connecting parts 41. The two ends of the spring 46 are fixedly connected to the adjacent connecting parts 41 respectively. By setting the spring 46, after the water quality testing is completed and the detection head 7 is pulled out of the municipal pipeline 5, the two connecting parts 41 are brought closer to each other by the retraction of the second electric telescopic rod 43 and the tension of the spring 46 restoring its deformation, and the rolling wheel 42 is retracted.

[0028] like Figure 1-3 As shown, the frame 1 is equipped with casters 8, which are used to move the device. When the positioning mechanism 4 adjusts the positioning, it is easy to move the frame 1. The frame 1 is also fixedly connected with a handle 9, which is convenient to push the device to move.

[0029] like Figure 1-3 As shown, a positioning ring 10 is fixedly connected to the frame 1, and the mounting cylinder 3 passes through the positioning ring 10. The positioning ring 10 helps the staff to initially locate the positions of the mounting cylinder 3 and the detection head 7, thereby improving the positioning efficiency.

[0030] like Figure 1-3 As shown, the connecting frame 6 includes a fixing rod 61 fixedly connected to the lower end face of the mounting cylinder 3. Multiple connecting rods 62 are fixedly connected to the periphery of the fixing rod 61. In this embodiment, four connecting rods 62 are fixedly connected. The detection head 7 is fixedly installed at the end of the connecting rod 62. Multiple detection heads 7 are provided to detect various water quality data.

[0031] like Figure 1-3As shown, two rollers 47 are rotatably connected to the mounting block 44. The rollers 47 are used to contact the inclined surface 45 to make the moving of the connecting piece 41 smoother. The upper end of the connecting piece 41 is provided with a shielding part 48. The cross-section of the shielding part 48 is inverted L-shaped. The openings of the two shielding parts 48 are close to each other. The shielding parts 48 are provided to prevent the mounting block 48 from coming off the two connecting pieces 41.

[0032] In this embodiment, all electrical devices are electrically connected to an external power source and to a control unit (not shown in the figure).

[0033] The working principle of a municipal water supply pipeline water quality testing device in this embodiment is as follows: When in use, the device is pushed above the municipal pipeline 5. The extension of the second electric telescopic rod 43 causes the mounting block 44 to contact the inclined surface 45, pushing the two connecting parts 41 away from each other. In conjunction with the extension of the first electric telescopic rod 2, the rolling wheel 42 contacts the inner wall of the municipal pipeline 5. During the process of the positioning mechanism 4 adjusting the mounting cylinder 3 to be centered inside the municipal pipeline 5, the frame 1 is moved. After the mounting cylinder 3 is centered inside the municipal pipeline 5, the detection head can then cooperate with the extension of the second electric telescopic rod 43 to perform water quality testing normally. By setting the positioning mechanism 4, the position of the detection head 7 is centered inside the pipeline, reducing the probability of the detection head 7 touching the inner wall of the municipal pipeline 5, protecting the detection head 7, and ensuring work efficiency.

[0034] 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.
