DETAILED DESCRIPTION
[0026] 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.
[0027] In the embodiment, Figure 1-4 A water surface oil film detection sensor is provided. The utility model comprises a monitoring well pipe 1 and a detection device 2. A clamping block 3 is fixedly connected to the top of the detection device 2. A clamping seat 4 is sleeved on the top of the clamping block 3. A threaded column 11 is fixedly connected to the top of the clamping seat 4. A supporting frame 15 is fixedly connected to the top of the monitoring well pipe 1. A lifting device 16 is fixedly installed on the top of the supporting frame 15. A lifting rope 17 is fixedly connected to the winding drum of the lifting device 16. The end of the lifting rope 17 away from the lifting device 16 is fixedly connected to the threaded column 11.
[0028] The lifting device 16 includes a driving motor and a winding disk. The driving motor is started to drive the winding disk to rotate, so that the winding disk winds up the lifting rope 17, thereby achieving the purpose of adjusting the height of the detection device 2.
[0029] A connecting rod 5 is fixedly connected to the side wall of the holder 4, a sliding seat 6 is fixedly connected to the inner wall of the monitoring well pipe 1, a sliding block 7 is fixedly connected to the outside of the connecting rod 5, and the sliding block 7 is slidably connected to the inside of the sliding seat 6. The detection device 2 is limited by the connecting rod 5, so that the detection device 2 can be lifted and lowered stably, thereby improving the stability of the structure.
[0030] The interior of the clamping seat 4 is fixedly connected with a limit rod 8, the top of the limit rod 8 is fixedly connected with a first wedge block 9, the first wedge block 9 is inserted into the interior of the clamping block 3, the interior of the clamping seat 4 is slidably connected with a second wedge block 10, and the external threaded connection of the threaded column 11 is connected with a rotating pressure plate 12.
[0031] The first wedge block 9 is in contact with the second wedge block 10 at an inclined surface. There are two first wedge blocks 9. A ball 13 is embedded on the top of the second wedge block 10. The rotating pressure plate 12 presses against the top of the ball 13. When the rotating pressure plate 12 moves downward, it pushes the second wedge block 10. The second wedge block 10 squeezes and limits the first wedge block 9, so that the first wedge block 9 limits the block 3 to maintain the stability of the structure.
[0032] A return spring 14 is provided on the outer sleeve of the limit rod 8, and the end of the return spring 14 away from the base 4 is fixedly connected to the first wedge block 9. When the rotating pressure plate 12 moves upward, the second wedge block 10 cancels the limiting state of the first wedge block 9, and the first wedge block 9 is pushed away by the elastic potential energy of the return spring 14, thereby canceling the limiting state of the first wedge block 9 with the card block 3, making it easy to remove the detection device 2 for maintenance, thereby improving the convenience of use.
[0033] The detection device 2 includes a signal processing unit 18, a laser 19 is fixedly installed at the bottom of the signal processing unit 18, a laser lens 20 is fixedly installed at the bottom of the laser 19, an imaging chip 21 is fixedly installed at the bottom of the signal processing unit 18, a filter 22 is fixedly connected to the bottom of the imaging chip 21, and a camera lens 23 is fixedly installed at the bottom of the filter 22.
[0034] The laser 19 excites the light source to emit pulsed ultraviolet light downward. If the ultraviolet pulse irradiates the water area containing oil or chemicals with aromatic hydrocarbons, it will cause electron transition and generate fluorescence of a specific wavelength. The imaging chip 21, the filter 22 and the camera lens 23 cooperate to receive and distinguish and filter the external light and the fluorescence spectrum reflected by the LED itself through the integrated multi-layer optical filter and software algorithm. Only the fluorescence spectrum of the specific area is retained, and the photosensitive element and function calculation are used to determine whether an oil film appears on the water surface. If an oil film is detected, the information will be transmitted to the controller through the data cable for alarm processing.
[0035] Working principle:
[0036] Start the lifting device 16 to make the winding drum unfold the lifting rope 17, so that the detection device 2 moves downward, and the detection device 2 is limited by the connecting rod 5, so that the detection device 2 can move stably, and the laser 19 excites the light source to excite pulsed ultraviolet light downward, and the reflected fluorescence spectrum is distinguished and filtered, and it is calculated to determine whether an oil film appears on the water surface. When the detection device 2 needs to be removed for maintenance, the rotating pressure plate 12 is rotated to move it upward, and the elastic potential energy of the reset spring 14 is used to push the first wedge block 9 away, so that the first wedge block 9 cancels the limiting state with the card block 3, which makes it easy to remove the detection device 2 for maintenance, thereby improving the convenience of use.
