One end of a support rod is hinged to the other side of the slider, and another end of the support rod is hinged to one side of an arc-shaped protective plate. A buffer spring is fixedly connected to one end of the slider. A telescopic rod is fixedly connected to one side of the filter screen cylinder, and a telescopic spring is sleeved on the outer wall of the telescopic rod. The end of the telescopic rod away from the filter screen cylinder is fixedly connected to the side of the arc-shaped protective plate. By providing the protective mechanism, the protective performance of the testing probe during testing inside a sewage source is improved.

[0004] Existing protective devices are difficult to disassemble and maintain during the protection of sewage level detection equipment, resulting in poor convenience for maintenance. Therefore, a protective device for sewage level detection equipment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a protective device for sewage level detection equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is a protective device for sewage level detection equipment, including a mounting plate. A fixing block is installed on the mounting plate by bolts. A protective cover is installed on the fixing block. The protective cover includes a first outer shell and a second outer shell. Tempered glass is installed on the bottom side of the first outer shell. An isolation cylinder is installed on the inner wall of the first outer shell. Multiple limiting plates are installed on the inner wall of the isolation cylinder. A probe is placed on the limiting plate. A cable is inserted into the probe. A first thread is provided on the outer wall of the isolation cylinder. A sealing ring is installed on the outer wall of the first outer shell. A second outer shell is placed on the first outer shell. A connecting cylinder is installed on the inner wall of the second outer shell. A second thread is provided on the inner wall of the connecting cylinder. A sealing plate is fixedly installed on the outer wall of the first outer shell. When disassembling the protective device, the second outer shell is rotated in the opposite direction. Then, the two second knobs and the first knob are rotated in the opposite direction respectively to achieve quick disassembly of the device. In practice, the probe needs to be maintained regularly, usually once a month. The device allows for convenient disassembly and maintenance, which is beneficial to improving the convenience of maintaining sewage level detection equipment.

[0007] Preferably, the second outer casing has a wire hole, in which two sealing semi-rings are placed. A first sealing gasket is installed on the inner wall of the sealing semi-ring, and a second sealing gasket is installed on the outer wall of the sealing semi-ring. A groove is formed on the outer wall of the sealing semi-ring. Two guide blocks are symmetrically installed on the inner wall of the connecting cylinder. The guide blocks have threaded holes, in which a first screw is fitted. A first knob is installed on the bottom side of the first screw. A lifting plate is rotatably connected to the first screw. A lifting groove is formed on the side wall of the connecting cylinder, and the lifting plate is fitted into the lifting groove. A sliding groove is formed in the lifting plate. A threaded hole is provided, and a second screw is installed in the threaded hole. A second knob is installed at one end of the second screw, and a locking block is rotatably connected to the other end of the second screw. The locking block is assembled in a sliding groove. By screwing the connecting cylinder on the second outer shell onto the isolation cylinder on the first outer shell, the second outer shell and the first outer shell are rotated and installed. When the second outer shell and the first outer shell are rotated and installed, the sealing plate on the second outer shell continuously presses the sealing ring on the first outer shell, thereby achieving a seal between the sealing plate and the first outer shell.

The device facilitates disassembly and maintenance, thus improving the convenience of maintaining sewage level detection equipment.

[0010] 2. In this utility model, the connecting cylinder on the second outer shell is screwed onto the isolation cylinder on the first outer shell. When the second and first outer shells are rotated and installed, the sealing plate on the second outer shell continuously presses the sealing ring on the first outer shell, thus achieving a seal between the sealing plate and the first outer shell. This structure can efficiently seal the probe, prevent sewage intrusion, protect the probe from the influence of sewage and other external environments, ensure the normal operation of the probe, and improve the sealing performance of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3 As shown, a protective device for a sewage level detection equipment includes a mounting plate 1. A fixing block 2 is bolted to the mounting plate 1, and a protective cover is mounted on the fixing block 2. The protective cover includes a first outer shell 3 and a second outer shell 4. Tempered glass 301 is mounted on the bottom side of the first outer shell 3. An isolation cylinder 302 is mounted on the inner wall of the first outer shell 3. Multiple limiting plates 303 are mounted on the inner wall of the isolation cylinder 302. A probe 5 is placed on the limiting plate 303, and a cable 501 is inserted into the probe 5. A first thread 304 is provided on the outer wall of the isolation cylinder 302, and a sealing ring 305 is mounted on the outer wall of the first outer shell 3. A second outer shell 4 is placed on the first outer shell 3. A connecting cylinder 401 is installed on the inner wall of the second outer shell 4, and a second thread 402 is provided on the inner wall of the connecting cylinder 401. A sealing plate 403 is fixedly installed on the outer wall of the first outer shell 3. During operation, the existing protective device is difficult to disassemble and maintain while protecting the sewage level detection equipment, resulting in poor convenience of maintenance. The sewage level detection equipment uses an ultrasonic level sensor, which is usually used to detect the sewage level. The ultrasonic level sensor model is SITRANS LUT400. The ultrasonic level sensor consists of a controller, a probe 5, and a cable 501. The cable 501 is plugged into the controller and the probe 5, and has a separate structure that can be physically separated. The principle of the ultrasonic level sensor is to send ultrasonic signals through the probe 5 and receive reflected signals, and calculate the liquid level height by measuring the time of ultrasonic waves. In practice, the probe 5 needs to be placed above the sewage to detect the sewage level. Therefore, the protective device needs to protect the probe 5.

[0020] By passing the cable 501 through the wire hole 404 of the second housing 4, and then placing the two sealing half-rings 405 inside the wire hole 404, the second knob 415 is rotated. The second knob 415 drives the second screw 414 to rotate and move horizontally at the same time. The second screw 414 drives the locking block 416 to move horizontally within the lifting plate 411, so that the two locking blocks 416 are locked in the locking grooves 417 of the two sealing half-rings 405. Then the two locking blocks 416 move relative to each other, pressing the two sealing half-rings 405, realizing the tight engagement of the two sealing half-rings 405, realizing the tight engagement of the two first sealing gaskets 406, realizing the tight engagement of the two first sealing gaskets 406 and the cable 501, and realizing the sealing of the cable 501 and the sealing half-rings 405.

[0021] Then, rotate the two first knobs 410 to drive the two first screws 409 to rotate. As the two first screws 409 rotate, they move downward. The two first screws 409 drive the two lifting plates 411 to move downward. The two lifting plates 411 drive the two locking blocks 416 on them to move downward. The two locking blocks 416 drive the two sealing half rings 405 to move downward. The two sealing half rings 405 press down on the two second sealing gaskets 407 on them, thus achieving the sealing of the two sealing half rings 405 and the wire hole 404.

[0022] After sealing the wire hole 404 of the cable 501 and the second housing 4, the probe 5 is inserted between the multiple limiting plates 303 of the isolation cylinder 302, thus realizing the installation of the probe 5 and the first housing 3; the plug of the cable 501 is inserted into the probe 5, thus realizing the connection between the cable 501 and the probe 5.

[0023] Then, the connecting cylinder 401 on the second outer shell 4 is screwed onto the isolation cylinder 302 on the first outer shell 3, thus achieving a fixed connection between the second outer shell 4 and the first outer shell 3. Previously, it was necessary to leave more cables 501 inside the shell and pre-twist the cables 501. When the second outer shell 4 and the first outer shell 3 are rotated and installed, the second outer shell 4 drives the cables 501 to rotate, loosening the cables 501 and preventing damage to the cables 501 during rotation. This structure does not exert much torsional force on the cables 501 and will not damage them. The above describes the assembly of the protective device. When disassembling the protective device, rotate the second outer shell 4 in the opposite direction, and then rotate the two second knobs 415 and the first knob 410 in the opposite direction to quickly disassemble the device. In practice, the probe 5 needs to be maintained regularly, usually once a month. The device allows for easy disassembly and maintenance, which helps to improve the convenience of maintaining the sewage level detection equipment.

[0024] Please see Figure 4-5As shown, the second outer casing 4 has a wire hole 404, in which two sealing half-rings 405 are placed. A first sealing gasket 406 is installed on the inner wall of the sealing half-ring 405, and a second sealing gasket 407 is installed on the outer wall of the sealing half-ring 405. A groove 417 is formed on the outer wall of the sealing half-ring 405. Two guide blocks 408 are symmetrically installed on the inner wall of the connecting cylinder 401. A threaded hole is formed on the guide block 408, and a first screw 409 is assembled in the threaded hole. A first spiral is installed on the bottom side of the first screw 409. A lifting plate 411 is rotatably connected to the first screw 409 via a knob 410. A lifting groove 412 is provided on the side wall of the connecting cylinder 401, and the lifting plate 411 is assembled in the lifting groove 412. A sliding groove 413 is provided in the lifting plate 411, and a threaded hole is provided on the side wall of the lifting plate 411. A second screw 414 is assembled in the threaded hole. A second knob 415 is installed at one end of the second screw 414, and a locking block 416 is rotatably connected to the other end of the second screw 414. The locking block 416 is assembled in the sliding groove 413. During operation, the existing... During the protection of the sewage level detection equipment, the protective device struggles to effectively seal the probe 5, resulting in poor sealing performance. The elliptical structure of the first and second outer shells 3 and 4 prevents debris accumulation. The tight interlocking of the two first sealing gaskets 406 seals the cable 501 and the sealing half-ring 405. The two sealing half-rings 405 press down on the two second sealing gaskets 407, sealing the two sealing half-rings 405 and the wire hole 404. When the connecting cylinder 401 on the second outer shell 4 is screwed onto the isolation cylinder 302 on the first outer shell 3, and the second and first outer shells 3 are rotated during installation, the sealing plate 403 on the second outer shell 4 continuously presses against the sealing ring 305 on the first outer shell 3, achieving a seal between the sealing plate 403 and the first outer shell 3. This structure provides an efficient seal for the probe 5, preventing sewage intrusion and protecting it from external environmental influences such as sewage, ensuring its normal operation and improving the device's sealing performance.

[0025] Working principle: Existing protective devices are difficult to disassemble and maintain when protecting sewage level detection equipment, resulting in poor maintenance convenience. Sewage level detection equipment uses ultrasonic level sensors, typically SITRANS LUT400 models. These sensors consist of a controller, probe 5, and cable 501. Cable 501 is plugged into the controller and probe 5, forming a separate structure that can be physically separated. The ultrasonic level sensor works by sending ultrasonic signals through probe 5 and receiving reflected signals, calculating the liquid level by measuring the duration of the ultrasonic waves. In practice, probe 5 needs to be placed above the sewage to detect the level; therefore, the protective device needs to protect probe 5. This is achieved by passing cable 501 through the wire hole 404 in the second housing 4, placing two sealing half-rings 405 inside the wire hole 404, and then rotating the second knob 4. 15. The second knob 415 drives the second screw 414 to rotate while moving horizontally. The second screw 414 drives the locking block 416 to move horizontally within the lifting plate 411, so that the two locking blocks 416 are locked in the slots 417 of the two sealing half-rings 405. Then, the two locking blocks 416 move relative to each other, pressing the two sealing half-rings 405, realizing the tight engagement of the two sealing half-rings 405, realizing the tight engagement of the two first sealing gaskets 406, realizing the tight engagement of the two first sealing gaskets 406 and the cable 501, and realizing the sealing of the cable 501 and the sealing half-rings 405. Then, the two first knobs 410 are rotated, driving the two first... As the screw 409 rotates, the two first screws 409 move downwards simultaneously. The two first screws 409 drive the two lifting plates 411 to move downwards, which in turn drive the two locking blocks 416 on them to move downwards. The two locking blocks 416 then drive the two sealing half-rings 405 to move downwards, pressing down on the two second sealing gaskets 407 on them, thus sealing the two sealing half-rings 405 and the wire hole 404. After sealing the wire hole 404 of the cable 501 and the second housing 4, the probe 5 is inserted between the multiple limiting plates 303 of the isolation cylinder 302, thus achieving the installation of the probe 5 and the first housing 3. The plug of cable 501 is inserted into probe 5, thus connecting cable 501 and probe 5. Then, the connecting sleeve 401 on the second housing 4 is screwed onto the isolation sleeve 302 on the first housing 3, thus fixing the second housing 4 and the first housing 3. Previously, more cables 501 needed to be left inside the housing and the cables 501 were pre-twisted. When the second housing 4 and the first housing 3 are rotated and installed, the second housing 4 drives the cables 501 to rotate, loosening the cables 501 and preventing damage to the cables 501 during rotation. This structure does not exert much torsional force on the cables 501 and will not damage the cables 501.The above describes the assembly of the protective device. When disassembling the protective device, rotate the second outer shell 4 in the reverse direction, then rotate the two second knobs 415 and the first knob 410 in the reverse direction respectively to achieve quick disassembly. In practice, the probe 5 needs regular maintenance, usually once a month. The device allows for convenient disassembly and maintenance, improving the ease of maintenance for wastewater level detection equipment. Existing protective devices struggle to effectively seal the probe 5 during the protection of wastewater level detection equipment, resulting in poor sealing performance. The elliptical structure of the first outer shell 3 and the second outer shell 4 prevents debris accumulation. The tight engagement of the two first sealing gaskets 406 effectively seals the cable 5. The sealing of the 01 and sealing half-rings 405 is achieved by pressing the two sealing half-rings 405 downwards onto the two second sealing gaskets 407, thus sealing the two sealing half-rings 405 and the wire hole 404. When the connecting cylinder 401 on the second outer shell 4 is screwed onto the isolation cylinder 302 on the first outer shell 3, and the second outer shell 4 and the first outer shell 3 are rotated for installation, the sealing plate 403 on the second outer shell 4 continuously presses against the sealing ring 305 on the first outer shell 3, achieving a seal between the sealing plate 403 and the first outer shell 3. This structure can efficiently seal the probe 5, preventing sewage intrusion and protecting the probe 5 from the influence of sewage and other external environmental factors, ensuring the normal operation of the probe 5 and improving the device's sealing performance.
