Description

Technical Field

[0001] The utility model relates to the technical field of water gate pressure detection, in particular to a water gate pressure detection device with self-cleaning function. Background Art

[0002] A sluice is an engineering structure used to control water flow. It is usually used in rivers, canals, reservoirs and other water bodies. The detection of sluice pressure plays a vital role in the normal operation of the sluice. Sluice pressure detection devices are usually installed at key positions of the sluice to ensure that changes in water pressure can be accurately detected. Pressure detection devices must be installed at the inlet and outlet of the sluice to monitor the pressure of water entering and leaving the sluice, and then adjust the height of the gate in time, thereby achieving the purpose of regulating the water level.

[0003] In the related art, the pressure detection device at the water inlet of a sluice gate generally detects the pressure of the upstream water flow through its positive pressure surface (water-facing surface). When water flows through the positive pressure surface of the detection device, the kinetic energy of the water will be converted into pressure. By setting a pressure detection device at this position, the pressure exerted by the water flow on the surface of the device can be measured, thereby obtaining the pressure information of the water flow. Therefore, accurate detection of the positive pressure surface of the pressure detection device is crucial.

[0004] Since the pressure detection device is arranged on the bottom wall of the sluice gate, it is usually located in the water. The environment in the water is complex, and there are often plastic bags, weeds, silt and other debris that can easily affect the detection effect of the positive pressure surface of the pressure detection device, thereby causing the sluice gate to be untimely adjusted. When cleaning these garbage in the prior art, a cleaning mechanism is usually used to clean the water-facing surface of the pressure detection device, while the surroundings of the pressure detection device are ignored, resulting in incomplete cleaning of the pressure detection device. Moreover, in the prior art, after the pressure detection device is installed on the bottom wall of the sluice gate, it is not convenient to disassemble and assemble the pressure detection device or to perform daily maintenance on the pressure detection device because the installation position is in the water. Utility Model Content

[0040] A water gate pressure detection device with self-cleaning function according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0041] like Figure 1-Figure 7As shown, a water gate pressure detection device with self-cleaning function provided in an embodiment of the present application includes a mounting plate 1 fixedly mounted on a side foundation at the water gate inlet, two sets of positioning mechanisms are connected to the mounting plate 1, a guide cover 17 is fixed to the lower part of the two sets of positioning mechanisms, and a sensor 20 for detecting the water gate pressure is installed in the guide cover 17.

[0042] The deflector 17 is cylindrical, with a side wall on the water-facing surface and an opening on the water-receiving surface. A plurality of water-permeable holes 19 are provided on the surface of the deflector 17 (the water-facing surface and the circumferential outer wall). The deflector 17 protects the sensor 20 and extends the service life of the sensor 20. At the same time, water can flow through the water-permeable holes 19, so that the sensor 20 can detect the pressure of the water flow in the sluice.

[0043] The positioning mechanism includes two groups of moving rods 5, which are respectively located at the two ends of the air deflector 17. The upper ends of the two moving rods 5 of each group are slidably connected to the mounting plate 1 (sliding connection is achieved through guide rails or rollers, etc., which will not be described in detail), and the lower ends are connected with semicircular arc clamps, and the openings of the arc clamps of the two moving rods 5 are arranged oppositely, and when closed, a clamping sleeve 6 is formed to clamp the end of the air deflector 17.

[0044] The outer walls at both ends of the air deflector 17 are provided with annular grooves 18, and a raised inner ring 8 is provided on the inner side of the arc-shaped clamp of the jacket 6. When the jacket 6 is fixed on the outside of the air deflector 17, the inner ring 8 is engaged with the annular groove 18, further improving the stability of the air deflector 17 being fixed.

[0045] The two groups of moving rods 5 are respectively installed in two positioning mechanisms, and the two positioning mechanisms are fixedly connected by a connecting plate 2. A bidirectional screw rod 4 is installed in each positioning mechanism, and two sections of reverse threads of the bidirectional screw rod 4 are respectively threadedly connected with the two moving rods 5 in the positioning mechanism. When the bidirectional screw rod 4 is rotated in one direction, the two moving rods 5 are closed with the jacket 6 to achieve stable clamping of the air deflector 17. When the bidirectional screw rod 4 is rotated in the other direction, the two moving rods 5 are opened with the jacket 6. When the sensor 20 needs to be repaired, the air deflector 17 and the sensor 20 are disassembled and assembled. In order to facilitate operation, either end of the bidirectional screw rod 4 can be exposed to a distance from the positioning mechanism during installation.

[0046] In order to clean the deflector 17 and ensure the accuracy of the sensor 20 in detecting the water flow pressure, a cleaning component is installed on the fixing mechanism in this embodiment, and the cleaning component cleans the outer wall of the deflector 17.

[0047] like Figure 5As shown, the cleaning assembly includes a limit rod 9, an arc brush 7 and a movable screw 9. In the arc clamps connected by two groups of movable rods 5, the limit rod 9 and the movable screw 9 are installed in parallel between the two arc clamps with the same opening direction. The arc brush 7 is installed in a sliding connection with the limit rod 9 and is threadedly connected with the movable screw 9. The bristles on the inner side of the arc brush 7 fit the outer wall of the air guide cover 17. The movable screw 10 is driven by a micro motor. The micro motor is installed inside the protrusion of the upper end of the arc clamp away from the gear 11, and is sealed to effectively isolate the influence of water flow on the micro motor. After the movable screw 10 is driven by the micro motor, the arc brush 7 slides on the limit rod 9 to clean the circumferential surface of the air guide cover 17, and the micro motor can rotate forward and reverse, prompting the movable screw 10 to rotate forward and reverse, so that the arc brush 7 moves back and forth.

[0048] Furthermore, the two movable screw rods 10 are connected to the gear 11 at one end close to the water-facing surface of the air deflector 17, and the second slide rail 12 is provided on one side of the two movable rods 5 close to the gear 11. The two second slide rails 12 are slidably connected with a rack 14, which is meshed with the gear 11. The lower side of the rack 14 is connected to a brush rod 16, which is located on the water-facing side of the air deflector 17. When the movable screw rod 10 drives the gear 11 to rotate, the rack 14 drives the brush rod 16 to move up and down to clean the water-facing surface of the air deflector 17 to prevent garbage from clogging the water permeable hole 19, thereby affecting the accuracy of the detection.

[0049] Considering that the rack 14 is easily separated from the second slide rail 12 when moving, a slide groove 13 is opened on one side of the second slide rail 12, and a protrusion 15 is set on one side of the rack 14. The protrusion 15 slides in the slide groove 13, and the rack 14 is restricted by the slide groove 13, so that the rack 14 can slide stably.

[0050] The self-cleaning water gate pressure detection device provided in this embodiment can be set on any side or both sides of the water gate water inlet, and its working process is: through the rotation of the bidirectional screw rod 4, the two groups of moving rods 5 are respectively closed with the corresponding two jackets 6, and the two ends of the deflector 17 are clamped and fixed, so that the sensor 20 is stably installed at the bottom of the water gate to stably detect the pressure of the water gate. When garbage is hooked on the surface of the deflector 17 after long-term use, the moving screw rod 10 is driven by a micro motor, and the two semicircular arc brushes 7 slide on the limit rod 9 through the rotation of the moving screw rod 10, and the water permeable holes 19 opened on the surface of the deflector 17 are cleaned by the arc brush 7. When the moving screw rod 10 rotates, the gear 11 is driven to rotate, and the gear 11 and the rack 14 are meshed, so that the rack 14 moves up and down with the brush rod 16, and the water guide surface of the deflector 17 is cleaned, thereby achieving comprehensive cleaning of the deflector 17.

[0051] The above are only embodiments of the present application and are not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0052] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
