[0002] A swimming pool is a place where people can swim or compete. Most swimming pools are built on the ground. They can be divided into ordinary swimming pools and heated swimming pools according to the water temperature. They can be divided into indoor, outdoor, and private swimming pools. Private swimming pools are usually built in villas.

[0003] When a swimming pool is in use, there are usually special lifeguards at public swimming pools to anticipate accidents that might happen to users while swimming. However, in order to ensure privacy during use, private swimming pools are not equipped with special lifeguards. This also results in outsiders or children not being able to be discovered immediately when they fall into the swimming pool.

However, since the swimming pool alarm needs to be monitored 24 hours a day, the use of sonar to monitor people who fall into the water has large power loss and high production costs. The sonar angle installation requirements are strict, and the monitoring range will be limited by the swimming pool environment. Therefore, it has not been widely popularized and applied in the market.

[0005] Therefore, how to provide a swimming pool alarm with a simple structure and can be widely used has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] Example 1

[0033] like Figure 1-5As shown, the utility model discloses a swimming pool alarm, which is arranged at the poolside of the swimming pool, including a shell, a monitoring mechanism, a control mechanism and an alarm mechanism. The shell is in a ╗ shape, and the shell includes an electronic component main body sealing tube 1, an L-shaped fixing clamp 2 and a swimming pool underwater main body warehouse tube 3. The electronic component main body sealing tube 1 is horizontally clamped at one end of the L-shaped fixing clamp 2, and the swimming pool underwater main body warehouse tube 33 is vertically clamped at the other end of the L-shaped fixing clamp 2, and both are fastened by bolts. The split shell structure is convenient for the installation of internal components and also convenient for mass production in the factory.

[0034] The monitoring mechanism is mainly arranged in the underwater main body warehouse pipe 3 of the swimming pool. The control mechanism and the alarm mechanism are both installed on the end plate of the electronic component main body sealed tube 1 and are located in the electronic component main body sealed tube 1. The monitoring mechanism and the alarm mechanism are both electrically connected to the control mechanism.

[0035] Specifically, the monitoring mechanism includes a magnetic conductor 4, a submersible floating float 5, a floating cover 6, a balancing sponge 7, a fixed interpenetrating hollow pipe head 8, a magnetic switch and a U-shaped card 9. The magnetic switch is arranged in the fixed interpenetrating hollow pipe head 8 through a cable. A plug-in portion is provided below the fixed interpenetrating hollow pipe head 8. A through hole is provided in the middle of the submersible floating float 5 and the floating cover 6 corresponding to the plug-in portion. The submersible floating float 5 and the floating cover 6 are slidably sleeved in the plug-in portion from bottom to top in sequence. The two ends of the plug-in portion are locked by the U-shaped card 9. More specifically, the submersible floating float 5 is a hollow round The columnar structure floats 1-2 cm underwater. The floating cover 6 is made of plastic. The cross section of the floating cover 6 is a stepped "X" shape. A through hole is provided on the top of the floating cover 6. The floating cover 6 is pressed on the submersible floating float 5 and is semi-suspended on the surface of the pool water. The magnetic conductor 4 is embedded in the submersible floating float 5. The balancing sponge 7 is cylindrical and made of EVA material. Two balancing sponges 7 are provided. The two balancing sponges 7 are symmetrically arranged in the middle of the floating cover 6. When the floating cover 6 is semi-submerged in the pool water, the lower end surface of the balancing sponge 7 just floats on the surface of the pool water.

[0036] The magnetic conductor 4 is embedded and installed in the cylindrical submersible buoy 5. If the water rises and falls, the magnetic conductor 4 of the cylindrical submersible buoy 5 will absorb the magnetic induction switch. When the magnetic induction switch is activated, it will communicate and transmit signals to give an alarm. The setting of the plastic floating cover 6 plays a role in pressing down the submersible buoy 5, adjusting the sensitivity of the monitoring mechanism, and increasing the sensing area. The increase in the buoyancy sensing area can effectively avoid false alarms caused by some slight water waves, and a water exhaust hole 10 is also reserved on the shell, which can prevent an alarm from being issued in the case of natural waves caused by natural wind and rain, thereby avoiding false alarms.

[0037] The setting of the balance sponge 7 effectively solves the problem of no water wave signal due to the far water drop point. The two balance sponges 7 are symmetrically installed in the plastic floating cover 6, which effectively increases the floating induction and improves the induction sensitivity of the water flow from underwater to upward. In this way, when the water pressure pushes upward from underwater, the buoyancy induction is more sensitive. After hundreds of tests, the utility model cleverly matches the buoyancy position of the underwater submersible sensing device, the semi-suspended sensing device, and the floating sensing device, and can accurately monitor the surface waves and the underwater upward motion water wave thrust, thereby achieving the effect of starting the alarm and avoiding the possibility of false alarms and no alarms.

[0038] As a preferred embodiment of the utility model, the monitoring mechanism also includes a waterproof fixed empty pipe 11 and a waterproof cap 12. A clamping groove is provided in the L-shaped fixed card 2 corresponding to the waterproof cap 12. The waterproof cap 12 is arranged in the clamping groove. The cable is arranged in the waterproof fixed empty pipe 11. One end of the waterproof fixed empty pipe 11 is threadedly connected with the fixed through-hole head 8. The other end of the waterproof fixed empty pipe 11 is inserted into the waterproof cap 12. The waterproof cap 12 is used for sealing the L-shaped fixed card 2 and the waterproof fixed empty pipe 11.

[0039] The alarm mechanism includes a plastic fixing plate 13, a buzzer 14 and a PCBA waterproof panel 15. The plastic fixing plate 13 is arranged at the port of the electronic component body sealing tube 1, the PCBA waterproof panel 15 is arranged on the inner side of the plastic fixing plate 13, the buzzer 14 is arranged on the PCBA waterproof panel 15, a sealing ring is arranged on the edge of the PCBA waterproof panel 15, and the buzzer 14 is electrically connected to the control mechanism.

[0040] As a preferred embodiment of the utility model, it also includes a surface cover waterproof plate, which is installed on the plastic fixing plate 13 and is used for waterproof sealing of the shell.

[0041] The control mechanism includes a battery waterproof fixing compartment 16 and a PCBA circuit board 17. The PCBA circuit board 17 and the battery waterproof fixing compartment 16 are sequentially arranged on the PCBA waterproof panel 15 from the outside to the inside. The buzzer 14 and the battery waterproof fixing compartment 16 are electrically connected to the PCBA circuit board 17, and the magnetic induction switch is electrically connected to the PCBA circuit board 17 through a cable.

[0042] As a preferred embodiment of the utility model, it also includes an LED alarm light and a transparent refractive lampshade 18. The transparent refractive lampshade 18 is arranged on the surface of the L-shaped fixing card 2, and the LED alarm light is fixed on the inner side of the transparent refractive lampshade 18. The LED alarm light is electrically connected to the PCBA circuit board 17. After the device alarms, the LED alarm light will flash synchronously to remind parents.

[0043] The utility model is used in the following way: firstly, the swimming pool alarm is installed on the deck at the edge of the swimming pool, and the underwater main body warehouse pipe 3 of the swimming pool is extended into the pool water to monitor the pool water. When a child falls into the swimming pool, the displacement of the water in the swimming pool generates a certain degree of moving water waves underwater, and the water waves reach the swimming pool alarm. Under the impetus of these moving water waves, the submersible buoy 5 cooperates with the magnetic induction switch to activate the magnetic induction switch, and detects a person falling into the water or a swimmer, so that the device emits a buzzing alarm sound and a lighted warning light to remind the child's parents.

[0044] Example 2

[0045] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the swimming pool alarm in this embodiment also includes an indoor alarm 19, and its PCBA circuit board 17 and the indoor alarm 19 are both provided with a wireless transmission module, the PCBA circuit board 17 and the indoor alarm 19 are wirelessly connected, and a display screen 20 is provided on the surface of the indoor alarm 19, which can set a monitoring mode, a swimming mode, an alarm mode, etc. When the swimming pool alarm sounds an alarm, the indoor alarm 19 will synchronously send a signal to remind indoor personnel that someone has fallen into the water, so as to avoid the situation where the person is indoors and does not hear the alarm.

[0046] As a preferred embodiment of the utility model, a magnetic switch hole 21 is provided on the PCBA waterproof panel 15, and a second magnetic switch is provided in the magnetic switch hole 21 and is also electrically connected to the PCBA circuit board 17. After the device alarms, the user can touch the magnetic induction point with a magnetic key to turn off the alarm.

[0047] Example 3

[0048] like Figure 7-9 As shown, the difference between this embodiment and embodiment 1 is that the swimming pool alarm in this embodiment further includes a leveling bracket, which is arranged on the lower end surface of the electronic component main body sealing tube 1 to ensure the horizontal installation of the alarm.

[0049] Specifically, the leveling bracket includes a bracket shell 22, a threaded pin 23, an adjustable leg 24 and a horizontal monitoring device. The bracket shell 22 is a rectangular structure. A threaded pin guide hole is provided in the middle of the bracket shell 22. The threaded pin 23 is inserted into the threaded pin guide hole. Four adjustable legs 24 are provided. The four adjustable legs 24 are respectively arranged at the corners of the bracket shell 22. The surface of the bracket shell 22 is provided with an installation groove, and the horizontal monitoring device is arranged in the installation groove.

[0050] The level monitoring device includes a level meter 25 arranged transversely and a level meter 25 arranged longitudinally.

[0051] When the swimming pool alarm needs to be installed on the swimming pool deck 26, the swimming pool alarm can be kept level by a leveling bracket and fixed to the swimming pool deck 26 by a threaded pin 23. The specific installation method is to first place the leveling bracket on the swimming pool deck 26 and adjust it to a horizontal state, and then fix one end of the threaded pin 23 to the mounting hole on the lower end surface of the electronic component body sealing tube 1, so that the threaded pin 23 passes through the threaded pin guide hole and is fixed to the swimming pool deck 26.

[0052] Example 4

[0053] like Fig.10 As shown, the difference between this embodiment and embodiment 3 is that in this embodiment, the bottom end of the adjustable leg 24 is provided with an anti-skid rubber pad, which can provide very strong adhesion, so that when the swimming pool deck 26 is made of a smooth material such as marble or tile, it can be firmly fixed on the surface of the swimming pool deck 26, thereby eliminating the need to drill holes in the swimming pool deck 26, thereby improving the applicability of the leveling bracket to different swimming pools.

[0054] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
