Description

Technical Field

[0001] This application relates to the technical field of liquid leakage alarms, and in particular to a liquid leakage alarm. Background Technology

[0002] Leakage alarms, as key devices for monitoring liquid leaks, are widely used in industrial pipelines, central air conditioning systems, chemical storage tanks, and laboratory piping. Their installation stability directly affects the timeliness and accuracy of monitoring. In industrial production, alarms need to be fixed to easily leaking locations such as pipe flanges and valves; in commercial buildings, they are often installed along air conditioning condensate pipes and fire protection pipelines; in laboratories, they need to be compatible with reagent pipelines of various diameters. These scenarios place diverse demands on the installation methods of alarms, requiring both robust reliability and ease of future maintenance and repositioning. Existing alarms and mounting bases are mostly integrated designs or fixed with multiple bolts. When maintenance, calibration, or replacement is required, the entire installation structure must be completely disassembled, resulting in time-consuming operations and poor practicality. Utility Model Content

[0004] The leakage alarm provided in this application adopts the following technical solution:

[0005] A leak alarm includes a mounting base and two sets of mounting components;

[0006] The mounting base is used to support and install the overall device;

[0007] The upper surface of the mounting base is provided with a leak alarm body, and the lower surface of the leak alarm body is symmetrically fixedly connected with fixing blocks, and fixing holes are opened on the opposite side of the two fixing blocks.

[0008] The upper surface of the mounting base is symmetrically provided with fixing grooves that slide with the fixing blocks. The interior of the mounting base is provided with a sliding groove, in which two sliders are slidably installed. A fixing rod is fixedly connected to the opposite side of each of the two sliders. One end of the fixing rod moves through the side wall of the sliding groove and extends into the fixing hole. The mounting base is provided with a driving component for driving the sliders to move.

[0009] Two sets of mounting components are symmetrically arranged on the lower surface of the mounting base. Each mounting component includes two arc-shaped clamping seats. Both arc-shaped clamping seats are fixedly connected to the lower surface of the mounting base and are arranged opposite to each other. A fixing bolt is provided on the side wall of the two arc-shaped clamping seats. The fixing bolt passes through the side wall of the arc-shaped clamping seat and is threadedly connected to it.

[0010] Preferably, the drive assembly includes a bidirectional lead screw and a connecting shaft. The bidirectional lead screw is rotatably mounted inside the slide groove. The bidirectional lead screw passes through two sliders and is threadedly connected to them. A worm gear is fixedly sleeved in the middle of the side wall of the bidirectional lead screw.

Compared to traditional single-plane mounting structures, it has a wider range of applications and can be stably installed in various scenarios such as industrial pipelines and laboratory piping. The drive assembly enables quick fixing and disassembly of the leak alarm body; simply turning the knob extends or retracts the fixing rod, eliminating the need for multiple bolts. This significantly reduces assembly and disassembly time compared to traditional methods, greatly improving the convenience of later maintenance and minimizing monitoring interruptions caused by maintenance.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a leak alarm. (Refer to...) Figure 1-4 A leak alarm includes a mounting base 1 and two sets of mounting components;

[0023] Mounting base 1 is used to support and install the overall device;

[0024] The upper surface of the mounting base 1 is provided with a leak alarm body 2, and the lower surface of the leak alarm body 2 is symmetrically fixedly connected with fixing blocks 6. Fixing holes 7 are opened on the opposite side of the two fixing blocks 6.

[0025] The upper surface of the mounting base 1 is symmetrically provided with fixing grooves 8 that slide with the fixing block 6. The interior of the mounting base 1 is provided with a sliding groove, in which two sliders 10 are slidably installed. The opposite sides of the two sliders 10 are fixedly connected with fixing rods 9. One end of the fixing rod 9 moves through the side wall of the sliding groove and extends into the fixing hole 7. The mounting base 1 is provided with a drive assembly for driving the sliders 10 to move.

[0026] The drive assembly includes a bidirectional lead screw 14 and a connecting shaft 11. The bidirectional lead screw 14 is rotatably mounted inside the slide groove. The bidirectional lead screw 14 passes through two sliders 10 and is threadedly connected to them. A worm gear 12 is fixedly sleeved in the middle of the side wall of the bidirectional lead screw 14. The connecting shaft 11 is rotatably mounted inside the slide groove. A worm gear 13 that meshes with the worm gear 12 is fixedly sleeved on the side wall of the connecting shaft 11. A knob 3 is fixedly connected to one end of the connecting shaft 11 after it movably passes through the side wall of the mounting base 1.

[0027] Two sets of mounting components are symmetrically arranged on the lower surface of the mounting base 1. The mounting components include two arc-shaped clamping seats 4. Both arc-shaped clamping seats 4 are fixedly connected to the lower surface of the mounting base 1 and are arranged opposite to each other. The side walls of the two arc-shaped clamping seats 4 are provided with fixing bolts 5. The fixing bolts 5 pass through the side walls of the arc-shaped clamping seats 4 and are threaded to them. The side walls of the fixing bolts 5 are provided with nuts 15 for pressing against the arc-shaped clamping seats 4. The arc-shaped clamping seats 4 are made of elastic material.

[0028] The implementation principle of a leak alarm in this application embodiment is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. When installing the overall device, according to the specifications of the pipe or bracket at the location to be monitored, the arc-shaped clamping seat 4 on the lower surface of the mounting base 1 is aligned with the target location. The arc-shaped clamping seat 4, being made of elastic material, can adapt to pipes of different diameters. Then, the fixing bolt 5 is inserted through the side walls of the two opposing arc-shaped clamping seats 4, and the nuts 15 are tightened to bring the two arc-shaped clamping seats 4 closer together and clamp the mounting surface, thus firmly fixing the mounting base 1 and preventing loosening in a vibrating environment. When installing the leak alarm body 2, the fixing block 6 on its lower surface is aligned with the fixing groove 8 on the upper surface of the mounting base 1 and inserted, ensuring a tight fit between the fixing block 6 and the fixing groove 8. Rotating the knob 3 drives the connecting shaft 11 to rotate, and the worm gear 13 on the connecting shaft 11 rotates accordingly. Because the worm gear 13 meshes with the worm wheel 12 on the bidirectional lead screw 14, it can drive the bidirectional lead screw 14 to rotate within the slide groove. A bidirectional lead screw 14 passes through and is threadedly connected to two sliders 10. Because the threads of the bidirectional lead screw 14 are opposite in direction, rotation causes the two sliders 10 to move away from each other within the groove, thereby pushing the fixing rod 9 out and inserting it into the fixing hole 7 of the fixing block 6, thus fixing the leak alarm body 2 to the mounting base 1. When it is necessary to disassemble the leak alarm body 2 for maintenance or replacement, the knob 3 is rotated in the opposite direction, causing the connecting shaft 11 to drive the worm gear 13 to rotate in the opposite direction, causing the bidirectional lead screw 14 to rotate in the opposite direction. The sliders 10 move closer together, and the fixing rod 9 is pulled out from the fixing hole 7, allowing the leak alarm body 2 to be removed from the mounting base 1. This operation is convenient and does not require disassembling the mounting base 1.

[0029] In this process, the installation assembly, which uses an arc-shaped clamp 4 in conjunction with fixing bolts 5 and nuts 15, can adapt to pipes of different diameters or cylindrical mounting surfaces. The elastic arc-shaped clamp 4 can fit tightly against the mounting surface, ensuring a firm fixation. Compared to the traditional single-plane mounting structure, it has a wider range of applications and can be stably installed in various scenarios such as industrial pipelines and laboratory pipelines. The drive assembly enables quick fixing and disassembly of the leak alarm body 2. Turning the knob 3 completes the extension and retraction of the fixing rod 9, eliminating the need for multiple bolts. This shortens the assembly and disassembly time compared to traditional methods, greatly improving the convenience of later maintenance and reducing monitoring interruption time caused by maintenance.

[0030] Here, the thread between the bidirectional lead screw 14 and the slider 10 can achieve self-locking. The self-locking condition depends on the helix angle, the coefficient of friction, and the load applied. The self-locking condition can be calculated using the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. When the lead angle (λ) of the worm 13 is less than the friction angle (φ) of the contact surface between the worm wheel 12 and the worm 13, the transmission system between the worm wheel 12 and the worm 13 can achieve self-locking. Through an external power device, the worm 13 can be driven to rotate clockwise and counterclockwise, thereby achieving clockwise and counterclockwise rotation of the worm wheel 12. The above content is all prior art. In practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here.
