[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0023] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] refer to Figures 1 to 4 This embodiment provides a device for treating water accumulation in an underground cable trench in a beach area, comprising a water collection well 2 arranged beside a cable trench 1, the water collection well 2 being connected to the cable trench 1 through a pipe 11, and a water level monitoring mechanism, a drainage mechanism and a control cabinet 3 being arranged in the water collection well 2. By setting up the water collection well 2, the accumulated water in the cable trench 1 can be discharged to the water collection well 2 through the pipe 11 in time, thereby ensuring the safe operation of the cable. The control cabinet 3 can select an STM-32 series single-chip microcomputer or a PLC controller to communicate with each electronic component, and perform signal input, output, conversion and calculation on each electronic component, thereby realizing intelligent control of the overall device.

[0025] The water level monitoring mechanism includes an ultrasonic level meter 4, which is arranged at the top of the water collection well 2, and the measuring end of the ultrasonic level meter 4 is facing the bottom of the water collection well 2. The ultrasonic level meter 4 realizes non-contact measurement of the water level in the water collection well 2, effectively avoiding the problem that the traditional level switch may be buried due to the accumulation of silt in the water, thereby failing to automatically start and stop drainage, and ensuring the accuracy and reliability of water level monitoring.

[0026] The drainage mechanism includes a submersible pump 5 and a drainage pipe 51 connected to the output port of the submersible pump 5 ; the water inlet of the submersible pump 5 is connected to an anti-blocking mechanism 6 .

[0027] The ultrasonic level meter 4 and the submersible pump 5 are both electrically connected to the control cabinet 3 .

[0028] The anti-blocking mechanism 6 includes a tube body 61 and a filter plate 62 and an anti-blocking plate 63 arranged in the tube body 61, the filter plate 62 is arranged in front of the anti-blocking plate 63, the anti-blocking plate 63 includes an outer ring 631 and a plurality of ribs 632, the ribs 632 coincide with the diameter of the outer ring 631, and the two ends of the ribs 632 are fixedly connected to the inner side wall of the outer ring 631; a plurality of filter holes 621 are evenly arranged on the filter plate 62, and a plurality of inserts 64 matching the filter holes 621 are arranged on the anti-blocking plate 63, the front end of the inserts 64 is conical, and the anti-blocking plate 63 is connected to the reciprocating drive mechanism. The anti-blocking mechanism 6 solves the problem that the water inlet of the submersible pump 5 is easily blocked by silt. The filter plate 64 is used to filter the debris and larger silt particles in the water when pumping water to prevent them from entering the submersible pump 5 and causing blockage. The fine silt and impurities will be extracted with the water flow. When the surface of the filter plate 64 is blocked, the anti-blocking plate 63 is driven to reciprocate by the reciprocating drive mechanism, and the insertion strip 64 on the anti-blocking plate 63 will be inserted into the filter hole 621 accordingly, thereby effectively clearing the filter plate 62 and ensuring the normal operation of the equipment.

[0029] The reciprocating drive mechanism includes a motor 65, a rectangular frame 66, a limit frame 67, a half gear 68 and a connecting rod 69. The limit frame 67 and the motor 65 are fixedly connected to the inner wall of the tube body 61, and the motor 65 is electrically connected to the control cabinet 3. The rectangular frame 66 is slidably arranged in the limit frame 67, and the top and bottom of the inner wall of the rectangular frame 66 are provided with tooth blocks 661. The output shaft of the motor 65 is fixedly connected to the half gear 68, and the half gear 68 is located in the moving frame, and the half gear 68 is meshed with the tooth block 661. The front end of the rectangular frame 66 is fixedly connected to the connecting rod 69, and the front end of the connecting rod 69 is fixedly connected to the anti-blocking plate 63. When work is required, the motor 65 is started, and the motor 65 drives the half gear 68 to rotate through the output shaft, and the half gear 68 will alternately mesh with the tooth blocks 661 at the top and bottom of the inner wall of the rectangular frame 66, so that the rectangular frame 66 reciprocates.

[0030] In this specific embodiment, the left and right inner walls of the limit frame 67 are provided with sliding grooves 671, and a sliding block 662 is slidably arranged in the sliding grooves 671, and the sliding block 662 is fixedly connected to the rectangular frame 66. The setting of the sliding grooves 671 and the sliding block 662 can limit the rectangular frame 66, ensuring that the movement trajectory of the rectangular frame 66 is a horizontal reciprocating motion.

[0031] In this specific embodiment, a water pressure sensor 7 is also installed at the water inlet of the submersible pump 5, and the water pressure sensor 7 is electrically connected to the control cabinet 3. The water pressure sensor 7 can monitor the water pressure at the water inlet of the submersible pump 5. If the water pressure decreases when the submersible pump 5 is working, it means that the submersible pump 5 may be blocked.

[0032] In this specific embodiment, a solar panel 8 and a battery 9 are further provided above the water collection well 2, and the battery 9 is electrically connected to the solar panel 8 and the control cabinet 3 respectively. The solar panel 8 can make full use of the solar energy in the beach area and save energy.

[0034] The working principle of the utility model is as follows:

[0035] When water accumulates in the cable trench 1, it will immediately enter the water collection well 2 through the pipe 11; the ultrasonic level meter 4 on the top of the water collection well 2 monitors the water level in the water collection well 2 in real time. When the water level in the water collection well 2 reaches the preset value, the signal is transmitted to the control cabinet 3, and the control cabinet 3 controls the submersible pump 5 to start working; when the submersible pump 5 is in working state, the water pressure sensor 7 detects that the water pressure value is small, which indicates that the water inlet of the submersible pump 5 is blocked, and the anti-blocking mechanism 6 is controlled to start working: the control cabinet 3 controls the motor 65 to start, and the motor 65 drives the half gear 68 to rotate through the output shaft. The half gear 68 will alternately mesh with the tooth blocks 661 at the top and bottom of the inner wall of the rectangular frame 66, so that the rectangular frame 66 performs horizontal reciprocating motion. The rectangular frame 66 drives the anti-blocking plate 63 to reciprocate through the connecting rod 69, and the insert 64 on the anti-blocking plate 63 will be correspondingly inserted into the filter hole 621, thereby effectively dredging the filter plate 62 to ensure the normal operation of the submersible pump 5.
