[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example

[0034] See also Figure 1-4 The utility model is a fall prevention net with self-locking and alarm functions for an inspection port, including an fall prevention net body 1 installed at the inspection port, and the fall prevention net body 1 includes: a partition net 11 adapted to be installed at the inspection port; a base 12, fixed to the middle position of the upper side of the partition net 11; a motor 14, fixed to the middle position of the upper side of the base 12; a swing arm 15, movably arranged on the shell edge of the motor 14; a bracket 13, movably arranged on the upper side of the base 12, and matched with the output shaft of the motor 14; a traction rod 16, movably connected to the end of the swing arm 15; a self-locking plate 17, fixed to the outer end of the traction rod 16.

[0035] Specifically, the inspection opening proposed in the present application uses an anti-fall net with self-locking and alarm functions to act on the inspection opening of the water outlet well at the top of the water outlet well. The anti-fall net body 1 is set to prevent the inspection opening from falling, so that the water collected in the rainy season can be reused, which is helpful to improve the ecological environment and realize the virtuous cycle of water ecology. The partition net 11 performs preliminary filtration on rainwater to remove larger branches, leaves and other debris, and a self-locking plate 17 is set, which is opened and closed by the driving system composed of a motor 14, a swing arm 15 and a traction rod 16 to realize the penetration adjustment of the partition net 11, so as to facilitate the discharge of rainwater to the downstream rainwater well when the water storage tank is full. The overall structural design is reasonable and has high practical value.

[0036] It should be noted that: when the motor 14 is started, the output shaft of the motor 14 drives the bracket 13 to rotate relative to the base 12. During this process, since the inner end of the traction rod 16 is connected and restricted by the swing arm 15, the traction rod 16 moves in a straight line along the inside of the movable groove 18 during the rotation, thereby driving the self-locking plate 17 fixed at the end of the traction rod 16 to adjust its position relative to the partition net 11, so as to adjust the flow of the partition net 11.

[0037] Furthermore, a hanging rope 110 is connected to the middle position of the lower side of the partition net 11 , and a liquid level sensor 111 is connected to the bottom of the hanging rope 110 .

[0038] Specifically, the hanging rope 110 is used for the installation of the liquid level sensor 111, and the liquid level sensor 111 is wirelessly connected to the external management end. When the liquid level reaches the warning position, the liquid level sensor 111 will feed back the sensing signal to the management end to realize the monitoring and alarm function of the anti-fall net body 1. This technology is a relatively mature technology at present and no further restrictive description is made here.

[0039] Furthermore, an annular notch is provided on the edge of the lower side of the partition net 11, and the annular notch cooperates with the mounting ring on the inner wall of the inspection port. The self-closing locking plate 17 is fitted on the upper side of the partition net 11, and an expansion groove which is movably adapted to the self-closing locking plate 17 is provided on the inner wall of the inspection port.

[0040] Specifically, the setting of the annular notch facilitates the installation of the partition net 11 and the inspection port, and the expansion groove set on the inner wall of the inspection port provides a movable space for the self-closing locking plate 17. The structural setting of the inner wall of the inspection port is to assist the installation of the anti-fall net body 1, and it will not be further described in detail here.

[0041] Furthermore, a movable groove 18 is provided on the peripheral side of the bracket 13 and is movably adapted to the traction rod 16. A positioning groove 19 is provided on the upper side of the self-locking plate 17 and is fixedly adapted to the outer end of the traction rod 16. The single body structure of the self-locking plate 17 is arranged in a ring shape. A through groove is provided on one side of the self-locking plate 17, and a limiting protrusion is provided integrally on the other side.

[0042] Specifically, the movable groove 18 is used to maintain the moving balance of the traction rod 16, and the positioning groove 19 is used for the multi-position installation of the traction rod 16. The self-locking plates 17 arranged in four annular structures are combined with each other to form a blocking surface for the partition net 11. On the contrary, after the self-locking plates 17 are unfolded, they do not interfere with the water permeability of the partition net 11. The through grooves and limiting protrusions on the edges of adjacent self-locking plates 17 cooperate with each other to simply seal the connection between adjacent self-locking plates 17, and also to maintain the balance during separation and contraction.

[0043] In this embodiment

[0044] The anti-fall net body 1 is mainly composed of a partition net 11, a base 12, a motor 14, a swing arm 15, a bracket 13, a traction rod 16 and a self-closing plate 17. The partition net 11 is adapted to be installed at the inspection port, and its uniformly hollowed-out polygonal structure not only ensures the firmness of the net body, but also facilitates observation of the situation in the inspection port. The base 12 is fixed in the middle position of the upper side of the partition net 11, providing stable support for other components.

[0045] The motor 14 is fixed at the middle position of the upper side of the base 12, and is the power source for driving the self-locking plate 17 to open and close; the swing arm 15 is movably arranged at the edge of the housing of the motor 14, and the swing arm 15 is driven to move by the rotation of the motor 14; the bracket 13 is movably arranged at the upper side of the base 12, and cooperates with the output shaft of the motor 14 to realize the transmission of power;

[0046] The traction rod 16 is movably connected to the end of the swing arm 15. When the swing arm 15 moves, it drives the traction rod 16 to move along a certain trajectory. The self-locking plate 17 is fixed to the outer end of the traction rod 16 and opens and closes with the movement of the traction rod 16. When the edges of adjacent self-locking plates 17 are in contact with each other, the annular surface formed by the self-locking plates 17 in the retracted state can completely block the upper part of the hollow area of ​​the partition net 11, thereby preventing people or objects from falling from the inspection port.

[0047] In addition, the anti-fall net is also equipped with a liquid level sensor 111 and an alarm system; the liquid level sensor 111 has a built-in wireless sensor module and an automatic alarm module, which can monitor the liquid level in the inspection port in real time. Once an abnormal liquid level (such as water accumulation) is detected, the wireless sensor module will immediately transmit a signal to the management terminal, triggering the alarm system to sound an alarm and reminding personnel to deal with it in time;

[0048] This design not only improves the safety of the inspection port, but also reduces the cost and difficulty of manual inspection through the automated alarm system. At the same time, the design of the self-closing lock plate allows the anti-fall net to remain in a retracted state when not in use, without affecting the normal use of the inspection port;

[0049] In general, this type of anti-fall net with self-locking and alarm functions for inspection openings is a very practical and efficient safety device, which is of great significance for improving the safety performance of inspection openings.
