Description

Technical Field

[0001] The invention relates to a muddy water camera, in particular to a muddy water camera which can replace muddy water within a certain observation range of the muddy water camera with clean water and can replace the clean water in time, belonging to the field of underwater observation and detection. Background Art

[0002] Underwater turbid water cameras are mainly used to capture images of objects in turbid water environments. The current technology is to integrate underwater cameras and underwater lighting into one, and seal a clean water tank at the front end of the underwater camera. The clean water tank is filled with clean water, and a transparent window is set in front of the observation angle of the corresponding clean water tank. The clean water tank is placed close to the object to be observed, and this method is used to collect clear images of the object.

[0003] Muddy water cameras combined with clean water tanks can be widely used in turbid water environments. Since the size design of the clean water tank is related to the field of view of the camera, the size of the clean water tank is much larger than the muddy water camera. The muddy water camera equipped with a clean water tank cannot be used in narrow spaces, such as pipelines, deep wells and other areas full of muddy water. Summary of the invention

[0004] In order to solve the above-mentioned shortcomings and defects of the prior art, the present invention aims to provide a muddy water camera that can be used in a narrow space. Specifically, it is achieved as follows:

[0005] A muddy water camera for timely replacement of clear water comprises a sealed shell, a camera movement and an LED lamp sealed in the sealed shell, and further comprises: a hanging pipe connected to the sealed shell, a watertight cable connected to the camera movement through a circuit, a mounting seat with a surrounding shape mounted on the sealed shell in front of the camera lens, and a ring on the edge surface of the mounting seat, a water-permeable isolation material mounted on the edge surface of the ring, the mounting seat, the ring and the water-permeable isolation material together form a field of view interval located in front of the camera lens, and a water pipe is connected to the mounting seat from the outside and is connected to the field of view interval through the mounting seat.

[0006] Furthermore, a circle of annular grooves is provided inwardly on the side wall of the outer opening of the mounting seat, and a plurality of water outlet holes connected to the field of view interval are opened on the annular groove. The water pipe joint is fixedly installed on the mounting seat through the water inlet screw hole provided on the ring, and the annular groove is connected to the water pipe joint fixedly connected to the mounting seat.

[0007] Furthermore, the water outlet holes are all inclined holes inclined to the corresponding radius of the center of the circle where the annular groove is located, and the inclination angles are consistent.

[0008] Furthermore, the water-permeable isolation material is an isolation foam board or an isolation sponge with water-permeable properties.

[0009] Furthermore, the mounting seat is in the form of a circular cylindrical structure, and its outer end portion and the end face of the collar are both curved surfaces or planes corresponding to and fitting against the wall of the object pool to be observed.

[0010] Furthermore, the camera movement is fixed in the sealed housing by means of a mounting bracket, the LED light is fixed on the sealed mounting plate by means of screws and is arranged isolated from the camera movement, the camera movement observes objects outside the sealed housing through a camera window that is sealed on the sealed housing, and the LED light irradiates light onto the object through a lamp head that is sealed on the sealed housing and the sealed mounting plate, thereby providing necessary lighting conditions for observation of the camera movement.

[0011] Furthermore, the camera window and the lamp head are fixed to the sealed housing through a pressure plate, the camera end cover is located on the back of the camera and is installed on the sealed housing, the circuit board is installed on the camera end cover, the camera end cover is equipped with a watertight socket, a sealing ring is installed between the camera housing and the camera end cover, a sealing ring is installed between the camera end cover and the watertight socket, a sealing ring is installed between the camera housing and the window glass, and a sealing ring is installed between the sealing mounting plate and the lamp head and the camera housing, thereby ensuring that the camera movement, LED lamp and circuit board are in a sealed space isolated from the outside world.

[0012] Furthermore, the watertight cable is vulcanized on the watertight plug through a vulcanized rubber seal and bent at 90 degrees to each other. After the watertight plug is connected to the watertight socket, power and signal transmission between the muddy water camera and the surface control host is realized.

[0013] Furthermore, the hanging tube is installed on the mounting end surface of the mounting seat, and the mounting end surface is provided with mounting screw holes, which can reliably fix the hanging tube on the mounting end surface of the mounting seat, and the mounting seat is fixed on the sealed housing of the muddy water camera by screws.

[0014] The working principle of the present invention is introduced as follows: the collar is provided with an internal thread for installation with a mounting seat, and the collar is provided with an internal thread for installation with a water pipe joint. After the water pipe joint and the water pipe are securely installed on the collar, high-pressure clean water is supplied through the water surface, so that muddy water in the camera's observation field angle can be replaced with clean water. The collar is provided with a curved surface that matches the required inner wall size of the observation pipe. After the isolation foam board is bonded to the curved surface of the collar, the isolation foam board can be closely matched with the inner wall of the pipe in the detection pipe, effectively ensuring that the replaced muddy water will not enter the camera's observation field angle again. The mounting base is provided with an annular water tank to ensure that high-pressure water enters the annular water tank through the collar. A plurality of oblique holes are provided in the annular water tank. The high-pressure water in the annular water tank enters the enclosed space formed by the muddy water camera, the mounting base, the collar and the isolation foam board through the oblique holes. The function of the oblique holes is that the high-pressure water forms a rotating water flow in the enclosed space, and the muddy water in the enclosed space can be discharged after passing through the isolation foam board, so that the clean water can be injected into the field of view in front of the camera to achieve the effect of observation in muddy water. The end face of the water inlet screw hole on the collar is provided with an installation screw hole, and the hanging pipe is fixedly installed on the collar by screws. At this time, the hanging pipe is convenient for placing the muddy water camera in the pipeline position to be observed, and the isolation foam board can also be attached to the inner wall of the pipeline through the hanging pipe. When the muddy water camera is used at a large water depth and the corresponding water supply pressure increases, the hanging pipe can ensure that the muddy water camera remains in place to provide an observation effect. There are installation screw holes on the circumference of the mounting base, and the mounting base can be fixedly installed on the sealed shell of the muddy water camera by screws. The mounting screw holes arranged around the circular ring are mainly used to enable the mounting base and the muddy water camera to maintain a relatively consistent angle, that is, the horizontal field angle direction of the camera remains perpendicular to the direction of the water inlet screw hole. When the muddy water camera is lowered into the inner wall of the pipe, the image observed by the camera movement remains consistent, making it easier to determine the position and posture of the observed object.

[0015] The beneficial effects of the present invention are as follows: by supplying high-pressure clean water on the water surface, the muddy water in the camera's observation field of view can be replaced with clean water. The collar is provided with a curved surface that matches the required inner wall size of the observation pipe. After the isolation foam board is bonded to the collar curved surface, the isolation foam board and the pipe can be closely matched, effectively ensuring that the replaced muddy water will not enter the camera's observation field of view again. The function of the inclined hole is that the high-pressure water forms a rotating water flow in the confined space, and the muddy water in the confined space can be discharged through the isolation foam board in a more integrated and parallel manner. The LED lamp is used to fill in the light for the photographed object, and the camera movement transmits the photographed picture to the water surface through a watertight cable. When the clean water area becomes muddy due to movement, the muddy water can be replenished again to discharge the turbid water body, realizing the function of replenishing clean water in real time, thereby meeting the muddy water environment in a narrow area, such as underwater exploration under a pipe and in a narrow gap. The structure is reasonable, does not occupy lateral space, and the assembly structure is convenient, easy to disassemble, assemble and ship. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Embodiment 1: A muddy water camera for timely replacement of clear water, comprising a sealed shell, a camera movement and an LED light sealed in the sealed shell, and also comprising: a hanging pipe connected to the sealed shell, a watertight cable connected to the camera movement through a circuit, a surrounding mounting seat installed on the sealed shell in front of the camera lens, and a ring on the edge surface of the mounting seat, a water-permeable isolation material installed on the edge surface of the ring, the mounting seat, the ring and the water-permeable isolation material together form a field of view interval located in front of the camera lens, and a water pipe is connected to the mounting seat from the outside and is connected to the field of view interval through the mounting seat. In actual use, the clean water injection equipment is installed on one end of the water pipe, and the other end of the water pipe is installed on the mounting seat. After the watertight cable is connected, the lifting pipe is installed on the sealed shell, and it can be placed vertically into the deep water area that needs to be explored. The equipment can be lowered, moved, turned, and other operations are achieved by controlling the lifting pipe. After reaching the predetermined depth, the collar and the permeable isolation material are brought close to and close to the pipe wall or well wall of the pipeline, and the water supply equipment is started. High-pressure water is injected from the water pipe and enters the field of view area in front of the camera through the water pipe. The original muddy water in the field of view area is discharged from the area through the permeable isolation material by the water inlet pressure of the clean water. After the field of view area is basically full of clean water, the water replacement is completed. At this time, the field of view area in front of the camera is full of clean water, which can provide a clear field of view for the camera to capture image information. When the clean water gradually becomes turbid and affects the line of sight after a period of use, it is attached to the wall again to inject clean water and discharge the muddy water, so as to achieve the effect of replacing clean water.

[0032] Embodiment 2: Based on Embodiment 1, a muddy water camera for timely replacement of clear water includes a sealed housing, a camera end cover, a camera movement, a mounting bracket, an LED lamp, a circuit board, a sealed mounting plate, a lamp head, a camera window, a pressure plate, a watertight socket, a watertight plug and a watertight cable. The camera movement is fixedly mounted in the sealed housing through the mounting bracket, the LED lamp is fixed to the sealed mounting plate through screws, the camera movement observes objects outside the sealed housing through the camera window sealedly mounted on the sealed housing, the LED lamp irradiates light onto the object through the lamp head sealedly mounted on the sealed housing and the sealed mounting plate, and provides necessary lighting conditions for the camera movement to observe, the circuit board provides power supply, signal control and video signal processing for the camera and the lighting lamp, and the camera window and the lamp head are fixed to the sealed housing through the pressure plate. A sealing ring is installed between the camera housing and the camera end cover, a sealing ring is installed between the camera end cover and the watertight socket, a sealing ring is installed between the camera housing and the window glass, and a sealing ring is installed between the sealed mounting plate and the lamp head and the camera housing, so as to ensure that the camera movement, the LED lamp and the circuit board are in a sealed space isolated from the outside. The watertight cable is vulcanized on the watertight plug through vulcanized rubber sealing. After the watertight plug is connected to the watertight socket, power and signal transmission between the muddy water camera and the surface control host is realized.

[0033] In one of the embodiments, the camera core is fixedly mounted inside the sealed housing via a mounting bracket, and the LED light is fixedly mounted outside the sealed housing via a sealed mounting plate.

[0034] With the above-mentioned design structure, the camera core and the LED light are arranged in isolation, which can ensure that the LED light inside the sealed housing will not reflect back into the camera core lens, affecting the camera's shooting effect. The camera core is directly installed on the sealed housing, which can ensure that the center of the camera lens is concentric with the center of the sealed housing, and ensure that the camera's captured image can be displayed in the center of the display screen. Multiple evenly arranged LED lights are installed outside the sealed housing, and the light can be evenly irradiated onto the object being photographed after being scattered by the lamp head, providing a good shooting effect.

[0035] In one of the embodiments, the watertight cable and the watertight plug are vulcanized into a 90-degree elbow, and after the watertight plug and the watertight socket are installed, the direction of the elbow and the watertight cable can be upward.

[0036] When the above structure is adopted, the length of the vulcanized head of the watertight plug and the watertight cable is minimized, which enables the muddy water camera to be applied to pipelines with narrower spaces, expanding the use environment of the muddy water camera. The watertight cable is oriented upward, which can also reduce the bending radius of the watertight cable in the pipeline, preventing the watertight cable from being bent during long-term use and reducing its service life.

[0037] like Figure 1 and Figure 2As shown, the muddy water camera includes a watertight cable 1, a water pipe joint 2, a water pipe 3, and a hanging pipe 4, wherein the watertight cable 1 is vulcanized on a watertight plug 24, the watertight plug 24 is mounted on a watertight socket 23 of a camera end cover 5, and the watertight cable 1 is used to supply power to an underwater lighting lamp and a camera and to transmit signals. The water pipe 3 is mounted on the water pipe joint 2, and the water pipe 3 is used to supply clean water to an underwater closed space through high-pressure water on the water surface. The water pipe joint 2 is fixedly mounted through a water inlet screw hole 152 provided on a collar 15, and an isolation foam plate 16 is bonded to the collar 15. After the high-pressure water on the water surface enters the mounting screw hole 144, the clean water enters the annular groove 141 provided on the mounting seat 14, and then enters the muddy water in the closed area through a plurality of inclined holes 142 provided on the mounting seat 14, and the muddy water is discharged through the isolation foam plate 16. At the same time, the pressure maintained in the closed area prevents the muddy water from entering the closed space again, thereby achieving the replacement of clean water. The hanging pipe 4 is mounted on the mounting end face 143 of the mounting seat 14, and the mounting end face is provided with a mounting screw hole 144, so that the hanging pipe 4 can be reliably fixed on the mounting end face 143 of the mounting seat 14. The mounting seat 14 is fixedly mounted on the sealed housing 6 of the muddy water camera by screws. The camera movement 8 is mounted inside the sealed housing 6 through the mounting bracket 7, the camera window 12 is assembled in the hole of the sealed housing 6, the LED lamp 10 is mounted outside the sealed housing 6 through the sealed mounting plate 9, the lamp head 11 is assembled on the sealed mounting plate 9 and the sealed housing 6, the lamp head 11 and the camera window 12 are fixed on the sealed housing 6 by screws 19 through the pressing plate 13, and the circuit board 20 is mounted on the camera end cover 5 for power supply and signal conversion of the camera and the lighting lamp. A sealing ring 20 is provided between the camera window 12 and the sealed housing, and between the sealed mounting plate 9 and the lamp head 11 and the sealed housing 6 to ensure that the camera movement 8 and the LED lamp 10 are in a waterproof space. The sealing shell 6 is fixedly connected to the camera end cover 5 by means of screws 22 , and a sealing ring 21 is installed between the sealing shell 6 and the camera end cover 5 to ensure waterproof isolation between the sealing shell 6 and the camera end cover 5 .

[0038] like Figure 3 , 4 As shown in Figure 5, in this embodiment, an annular groove 141 is provided at the connection between the mounting seat 14 and the collar 15. The clean water entering through the water inlet screw hole 152 of the collar 15 fills the inside of the annular groove 141 of the mounting seat 14. A plurality of water outlet inclined holes 142 are also provided inside the annular groove 141 of the mounting seat 14. The clean water enters the closed space through the inclined holes 142. The arrangement of the inclined holes 142 is to facilitate the quick removal of the muddy water on the outermost side of the closed space. At the same time, the plurality of inclined holes 142 form a closed arc vortex, and all the muddy water in the closed space is removed through the isolation foam plate 16, so that the observation angle of the muddy water camera is all clean water.

[0039] like Figure 6As shown, in this embodiment, the mounting seat 14 is provided with a mounting end face 143, and the mounting end face 143 is provided with a mounting screw hole 144, and the hanging pipe 4 is fixedly mounted on the mounting seat 14 through the mounting screw hole 144. Through the hanging pipe 4, the muddy water camera is placed at the pipeline position to be observed and the position and posture of the muddy water camera in the pipeline are maintained.

[0041] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
