For those skilled in the art, the specific meaning of the above terms in the present application can be understood in combination with the specific circumstances.

[0028] The present application will be described below with reference to the accompanying drawings Figures 1 to 5 and in conjunction with the embodiments.

[0029] The utility model relates to a kind of water leakage detection devices for water leakage detection in heating valve well, water supply valve well, heating tunnel, water supply tunnel. Including including the main body cylinder 1 formed with inner cavity, installation shell 3 is arranged in the upper position in main body cylinder 1, motor 301 is fixedly arranged in installation shell 3, screw rod 4 is fixedly arranged at the end of motor 301, first moving block 401 is screw-connected on screw rod 4, first liquid level sensor 403 is arranged on first moving block 401, second moving block 402 is rotatably connected at the bottom end of screw rod 4, second liquid level sensor 404 is arranged on second moving block 402;Wherein, first moving block 401 and second moving block 402 are slidably connected with the inner side wall of main body cylinder 1, and a plurality of water inlet holes 101 are arranged at the interval of the side wall of main body cylinder 1.

[0030] In detail, as shown in Figure 1 And Figure 2 The main body cylinder 1 is the support base of the entire device, and its interior can be used to accommodate other components, providing a spatial basis for detecting water leakage levels. The water inlet holes 101 allow external water sources to enter the main body cylinder 1, and the first liquid level sensor 403 and the second liquid level sensor 404 on the screw rod 4 can determine the water leakage situation and liquid level height in the area. Additionally, the forward and reverse rotation of the motor 301 can drive the screw rod 4 to rotate, causing the first moving block 401 to ascend or descend on the screw rod 4, thereby adjusting the distance between the first liquid level sensor 403 and the second liquid level sensor 404 to meet different detection needs.

[0031] It should be noted that after installing the main body cylinder 1 to the measurement area, its end portion should be in abutment with the ground. When water leakage occurs, water will enter the main body cylinder 1 through the water inlet holes 101, and an alarm will be triggered when the water level reaches the first liquid level sensor 403 and the second liquid level sensor 404. In specific implementation, the water level changes at different positions may be different. By monitoring two points (i.e., the first liquid level sensor 403 and the second liquid level sensor 404), it is easier to identify the pattern of water level anomalies, thereby more accurately locating the water leakage point. The two measurement points can also be used to detect the rate of water level change, which helps to distinguish between normal water level fluctuations and rapid water level changes caused by water leakage. Adjusting the distance between the first liquid level sensor 403 and the second liquid level sensor 404 can meet the needs of different liquid level detection, making the utility model have high flexibility and accuracy, suitable for various occasions requiring water leakage detection.

[0032] Based on the above settings, to further increase the detection flexibility of the utility model, as shown in Figure 2 And Figure 5As shown, in this embodiment, the mounting shell 3 is slidably connected to the inner wall of the main body cylinder 1, the top shell 5 is fixedly provided on the top of the main body cylinder 1, and the cylinder 501 is fixedly provided inside the top shell 5. The end of the cylinder 501 extends into the main body cylinder 1 and is fixedly connected to the top of the mounting shell 3.

[0033] In this embodiment, the cylinder 501 can drive the mounting shell 3 to slide, thereby driving the screw 4 to slide up and down, thereby simultaneously adjusting the position of the first liquid level sensor 403 and the second liquid level sensor 404 in the main body cylinder 1, thus adapting to different detection requirements.

[0034] As a preferred structure in this embodiment, such as Figure 3 As shown in Figure 4, in this embodiment, a bottom cone 2 is fixedly provided at the bottom of the main body cylinder 1. The bottom cone 2 is conical in shape and its end faces downward. This configuration facilitates the insertion of the main body cylinder 1 into soft soil, makes it easier to fix the device, and prevents accidents during testing.

[0035] In this embodiment, a partition 102 is fixedly installed at the water inlet 101. The partition 102 can prevent impurities from entering the main body cylinder 1 and affecting the accuracy of the detection. Preferably, a temperature sensor 405 is also fixedly installed on the first moving block 401 and the second moving block 402. The temperature sensor 405 can detect the water temperature, thereby determining the leakage situation.

[0036] Continue as Figure 3 As shown in Figure 4, in this embodiment, in order to increase the stability of the device after installation, the side wall of the main body cylinder 1 is also provided with a support assembly. The support assembly includes a mounting sleeve 6 that is slidably fitted on the main body cylinder 1, a fixing block 601 that is symmetrically fixed on the mounting sleeve 6, a slot 602 opened in the fixing block 601, a first rotating shaft 603 whose two ends are fixedly connected to the inner side wall of the slot 602, and an upper rod 605 that is rotatably connected to the first rotating shaft 603. The bottom end of the upper rod 605 is slidably connected in the lower rod 606. A first torsion spring 604 is fitted on the first rotating shaft 603. A spring 607 is provided between the upper rod 605 and the lower rod 606. One end of the spring 607 is fixedly connected to the bottom surface of the upper rod 605, and the other end is fixedly connected to the top surface of the lower rod 606.

[0037] In practice, after the main body cylinder 1 is placed, the bottom of the lower rod 606 will contact the ground, providing support for the main body cylinder 1. The spring 607 can buffer the upper rod 605 and the lower rod 606, which is beneficial for shock absorption in case of accidents. In addition, the first torsion spring 604 also provides a certain buffering effect when the whole body shakes, increasing the overall stability. Furthermore, the mounting sleeve 6 can slide up and down on the main body cylinder 1 to adjust to the optimal support position. The mounting sleeve 6 is limited by the friction between it and the outer wall of the main body cylinder 1.

[0038] In addition, the bottom end of the lower rod 606 is provided with a placing assembly, which comprises a base 7, an inner groove 701 formed in the top, and a second rotating shaft 702 fixedly connected with the side wall of the inner groove 701 at both ends, the bottom end of the lower rod 606 is rotationally connected with the second rotating shaft 702, and a second torsional spring 703 is further sleeved on the second rotating shaft 702.

[0039] It should be further explained that the base 7 can increase the contact area of the lower rod 606 with the ground, further increasing the stability after the main body cylinder 1 is installed, in addition, the second torsional spring 703 can ensure the reset of the base 7 after adapting to the uneven ground.

[0040] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
