After detecting a leak, many systems do not drain the leak in a timely and thorough manner. Some drain devices have simple structures and unreasonable suction port designs, which cannot collect the leak quickly and effectively.

[0026] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0027] Please refer to Figures 1-6 In the embodiment of the present application, a liquid leakage self-warning and self-draining system comprises an accumulated liquid tray 1, wherein the accumulated liquid tray 1 is internally provided with a drainage pump base 5 and is fixedly connected with the accumulated liquid tray 1; the drainage pump base 5 is fixedly connected with a drainage pump 9 at the top end of which a controller 2 is fixedly connected; the drainage pump 9 is provided with a vacuum liquid suction pipe 3 and a drainage pipe 4 at both sides thereof; and the drainage pump base 5 is provided with a liquid leakage detection sensor 6 at one side thereof, and the liquid leakage detection sensor 6 is provided with a fixed assembly 7 at both sides thereof.
[0028] By adopting the above technical scheme, the fixed assembly 7 provided at both sides of the liquid leakage detection sensor 6 can ensure that the liquid leakage detection sensor 6 maintains a stable position in the accumulated liquid tray 1. The special structure of the fixed assembly 7, including the fixed plate 71, the fixed block 73 movably connected with the fixed seat 72, and the clamping block 74 threadedly connected with the fixed seat 72 through the lead screw, etc., can enable the liquid leakage detection sensor 6 to accurately detect the liquid leakage in the accumulated liquid tray 1 even if the liquid leakage detection sensor 6 may encounter vibration, shaking, etc. during the operation of the equipment. This effectively avoids the problems of inaccurate detection or missed detection caused by the displacement of the liquid leakage detection sensor 6, thereby providing reliable protection for timely detection of liquid leakage. When liquid leakage occurs, the liquid leakage detection sensor 6 detects the liquid leakage and transmits a signal to the controller 2, and the buzzer warning device connected with the controller 2 will emit an alarm sound. At the same time, the controller 2 can quickly respond and immediately start the drainage pump 9, so that the liquid leakage in the accumulated liquid tray 1 can be timely drained in the early stage of liquid leakage, thereby minimizing the damage caused by the accumulation of liquid leakage in the accumulated liquid tray 1 to the equipment, preventing the liquid leakage from corroding the equipment components and affecting the normal operation of the equipment, etc.
[0029] In the embodiment, the fixed assembly 7 comprises a fixed plate 71, the fixed plate 71 is fixedly connected with a fixed seat 72 at the top thereof, and the fixed seat 72 is provided with a recess at the top thereof, the recess is provided with a fixed block 73, and the fixed block 73 is movably connected with the fixed seat 72 through a shaft pin at one end thereof; a slot-shaped hole is formed in the middle part of the fixed block 73 and penetrates through the entire fixed block 73, and a clamping block 74 is arranged in the slot-shaped hole; and the clamping block 74 is fixedly connected with a lead screw at the bottom end thereof, and the other end of the lead screw is threadedly connected with the fixed seat 72.
[0030] By adopting the above technical scheme, one end of the fixed block 73 is movably connected with the fixed seat 72 through a shaft pin, and the rotating clamping block 73 after the installation of the liquid leakage detection sensor 6 clamps and fixes the fixed block 73; during the operation of the equipment, various vibrations are often generated, and the structure of the fixed assembly 7 can effectively absorb and disperse the influence of these vibrations on the liquid leakage detection sensor 6, the shaft pin connection allows a certain degree of relative movement, and when the vibration is transmitted to the liquid leakage detection sensor 6, the buffering effect can be achieved, and the impact of the vibration on the internal precision components of the liquid leakage detection sensor 6 is reduced; at the same time, through the fastening effect of the clamping block 74 and the screw rod, even in a vibrating environment, the sensor can also be ensured not to be displaced or loosened, the false alarm or missed alarm caused by vibration is reduced, and the stability and reliability of the detection are ensured.
[0031] In the embodiment, the bottom of the liquid leakage detection sensor 6 is provided with a screw rod and is threadedly connected with the liquid collection disc 1.
[0032] By adopting the above technical scheme, the threaded connection of the screw rod and the liquid collection disc 1 makes the installation height of the liquid leakage detection sensor 6 flexible to adjust, and the appropriate detection height may be different under different equipment working conditions and liquid leakage scenes; appropriately adjusting the position of the liquid leakage detection sensor 6 can timely trigger detection when the liquid level rises to a certain extent, and the height-adjustable feature can better adapt to diversified liquid leakage detection needs and optimize the detection effect; at the same time, the installation of the liquid leakage detection sensor 6 is also convenient, compared with some complex connection methods, the threaded connection is relatively simple and easy to operate, and the operator only needs to align the screw rod with the threaded hole on the liquid collection disc 1, and then the installation can be completed by rotating the liquid leakage detection sensor 6; and when the liquid leakage detection sensor 6 needs to be maintained, replaced or repositioned, it can also be conveniently and quickly disassembled, and the convenience of installation and disassembly can effectively save time and labor cost in the process of equipment installation, debugging and subsequent maintenance, and improve work efficiency.
[0033] In the embodiment, one side of the liquid leakage detection sensor 6 is provided with a transmission line 8 and is electrically connected with the liquid leakage detection sensor 6, and the other end of the transmission line 8 is electrically connected with the controller 2.
[0034] By adopting the technical scheme, when the liquid leakage detection sensor 6 detects a liquid leakage, an electric signal is immediately generated, which is transmitted to the controller 2 through the transmission line 8. Since the transmission line 8 is stably and reliably electrically connected with the two, the loss and delay in the signal transmission process can be minimized. After receiving the signal from the liquid leakage detection sensor 6, the controller 2 analyzes and processes the signal according to the preset logic program. Once it is determined that there is a liquid leakage risk, a trigger instruction is immediately sent to the buzzer connected with the controller 2. Since the controller 2 and the buzzer are also electrically connected, the instruction can be instantly transmitted, so that the buzzer can quickly emit an alarm sound, and the liquid discharge pump 9 can be started to discharge the liquid leakage. This accurate triggering mechanism avoids false positives and false negatives, and ensures that the alarm is started only when the liquid leakage is actually detected, providing accurate liquid leakage warning information for the staff.
[0035] In the embodiment, the vacuum liquid suction pipe 3 is connected with the liquid accumulation disc 1 at one end and has a liquid suction opening, and the other end extends into the liquid discharge pump 9 and is fixedly connected with the liquid discharge pump 9. The liquid discharge pipe 4 is fixedly connected with the liquid discharge pump 9 at one end and extends to the outside of the liquid accumulation disc 1 at the other end.
[0036] By adopting the technical scheme, the vacuum liquid suction pipe 3 is connected with the liquid accumulation disc 1 at one end and has a liquid suction opening. This kind of design can maximize the coverage of the area where liquid leakage may occur in the liquid accumulation disc 1, ensuring that no matter where the liquid leakage occurs in the liquid accumulation disc 1, the liquid leakage can be effectively sucked in through the liquid suction opening.
[0037] The liquid discharge pipe 4 is fixedly connected with the liquid discharge pump 9 at one end and extends to the outside of the liquid accumulation disc 1, providing a clear and efficient liquid discharge path for the liquid leakage. The liquid discharge pump 9 pressurizes the liquid leakage sucked from the vacuum liquid suction pipe 3 and smoothly discharges it outside the liquid accumulation disc 1 through the liquid discharge pipe 4, preventing the liquid leakage from remaining in the liquid accumulation disc 1. This helps to keep the liquid accumulation disc 1 clean, reduces the impact of liquid leakage on the subsequent operation of the equipment, and also reduces the risk of equipment failure and safety hazards caused by residual liquid leakage.
[0038] In the embodiment, the vacuum liquid suction pipe 3 and the liquid discharge pipe 4 are made of acid and alkali corrosion resistant high polymer materials.
[0039] By adopting the technical scheme, in many industrial scenarios such as chemical industry, pharmaceutical industry, electroplating industry and the like, the composition of the liquid leakage may be various, covering various acidic, alkaline and corrosive chemicals. The vacuum liquid suction pipe 3 and the liquid discharge pipe 4 made of acid and alkali corrosion resistant high polymer materials can ensure that they are not rapidly corroded and damaged when in contact with them, ensuring that the system can still operate normally for liquid suction and discharge in complex and diverse liquid leakage environments.
[0040] In the embodiment, the connecting heads at both ends of the transmission line 8 are designed with waterproof, dustproof and anti-loosening structure.
[0041] By adopting the above technical scheme, the design avoids the erosion and damage of water and dust to the connecting head and the internal circuit of the transmission line, and the water may cause short circuit and corrosion of the circuit, and the dust may wear the insulation layer of the circuit or cause blockage of the circuit; by effectively blocking these environmental factors, the service life of the transmission line 8 can be prolonged, the frequency of replacement due to transmission line failure can be reduced, and the equipment maintenance cost can be reduced.
[0042] The working principle of the utility model is: through the fixed assembly 7 arranged on both sides of the liquid leakage detection sensor 6, the stable position of the liquid leakage detection sensor 6 in the liquid accumulation tray 1 can be ensured, the special structure of the fixed assembly 7 contains the fixed plate 71, the fixed block 73 movably connected with the fixed seat 72 and the clamping block 74 screwed with the fixed seat 72 through the lead screw, so that the liquid leakage detection sensor 6 can still accurately detect the liquid leakage in the liquid accumulation tray 1 even if it may encounter vibration, shaking and other situations during equipment operation; this effectively avoids the problem of inaccurate detection or missed detection caused by the displacement of the liquid leakage detection sensor 6, thereby providing reliable protection for timely detection of liquid leakage; when liquid leakage occurs, the liquid leakage detection sensor 6 detects liquid leakage and transmits a signal to the controller 2, and the buzzer warning device connected with the controller emits an alarm sound; at the same time, the controller 2 can quickly respond and immediately start the liquid discharge pump 9, which can timely discharge the liquid leakage in the liquid accumulation tray 1 in the early stage of liquid leakage, thereby minimizing the damage caused by the accumulation of liquid leakage in the liquid accumulation tray 1 to the equipment, preventing liquid leakage from corroding equipment components and affecting normal operation of the equipment, and the like.
[0043] The threaded connection of the lead screw at the bottom of the liquid leakage detection sensor 6 and the liquid accumulation tray 1 enables the installation height of the liquid leakage detection sensor 6 to be flexibly adjusted, and the appropriate detection height may be different under different equipment working conditions and liquid leakage scenarios; appropriately raising the position of the liquid leakage detection sensor 6 enables it to timely trigger detection when the liquid level rises to a certain extent, and this height-adjustable feature can better adapt to diversified liquid leakage detection needs and optimize detection effect; at the same time, the installation of the liquid leakage detection sensor 6 is also convenient, compared with some complex connection methods, the threaded connection is relatively simple and easy to operate, and the operator only needs to align the lead screw with the threaded hole on the liquid accumulation tray 1, and then the installation can be completed by rotating the liquid leakage detection sensor 6; moreover, when the liquid leakage detection sensor 6 needs to be maintained, replaced or repositioned, it can also be conveniently and quickly disassembled, and this convenience in installation and disassembly can effectively save time and labor costs during equipment installation, debugging and subsequent maintenance process, and improve work efficiency.
