[0019] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0020] The embodiment of the present application provides a CCD camera module to solve the problem that dust is easily present at the camera lens position of the existing CCD camera module during actual operation. The dust will cause black shadows to be produced when the camera is working and taking pictures, thereby affecting the detection work of the camera. In addition, the camera is exposed to the outside without protection and has poor stability.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model embodiment discloses a CCD camera module according to the attached Figure 1-2 As shown, it includes a first protective shell 1 and a second protective shell 2 arranged outside a camera body 5, and the first protective shell 1 and the second protective shell 2 are clamped and sealed;

[0023] The second protective housing 2 is provided with a protective glass 4;

[0024] The outer side of the second protective shell 2 is provided with a lens protective cover 3, and the lens protective cover 3 is provided with an air and water channel joint 301, which connects the air and water pipelines.

[0025] Furthermore, a docking plate 201 is provided on the second protective shell 2, and the docking plate 201 is fixed to the first protective shell 1 by bolts, so that the first protective shell 1 and the second protective shell 2 are conveniently docked, thereby facilitating the clamping and protection of the camera body 5.

[0026] Furthermore, a first sealing ring 202 is movably connected between the first protective shell 1 and the docking plate 201. The design of the first sealing ring 202 can seal the interface between the first protective shell 1 and the docking plate 201, so that the first protective shell 1 and the second protective shell 2 provide sealing protection for the camera body 5.

[0027] It is particularly disclosed that a second sealing ring 203 is movably connected between the second protective shell 2 and the lens protective cover 3, and the second sealing ring 203 is used to seal between the second protective shell 2 and the lens protective cover 3, so that the air path will not form a channel from the interface position of the second protective shell 2 and the lens protective cover 3.

[0028] Specifically, the first protective shell 1 and the second protective shell 2 are formed in one piece, the protective glass 4 is fixed to the second protective shell 2 with sealing glue, and the protective glass 4 and the second protective shell 2 are sealed, which has a good protection effect on the camera body 5.

[0029] The CCD camera module is convenient for providing sealing and protection for the camera body 5. With the design of the protective glass 4, the lens protective cover 3 and the air and water channel connector 301, the camera body 5 lens position can be automatically cleaned to prevent dust from affecting the operation of the camera body 5.

[0030] The air / water channels enter from the air / water channel joint 301, and then flush the protective glass 4 inside the lens protective cover 3. When not working, water is passed to keep the protective glass 4 moist and not easy to stick to dust. Before working, blow air to dry the protective glass 4, and then take pictures;

[0031] When the air path is connected, the cavities of the second protective housing 2 and the lens protective cover 3 are filled with air, and the air path enters the air from the position where the cross-sectional area of ​​the cavity is small, generating a Venturi effect, thereby preventing external dust and water droplets from entering the interior of the lens protective cover 3 and the second protective housing 2, thereby ensuring that the surface of the protective glass 4 remains clean;

[0032] The Venturi effect is that when a fluid contracts through a pipe or an obstacle, a high flow rate will be generated, while the flow rate will decrease when it diffuses. According to the Bernoulli equation, a low-pressure area or a high-pressure area is generated, thereby preventing external dust from entering the protective glass 4 position.

[0033] In summary, the CCD camera module adopts the first protective shell 1, the second protective shell 2 and the protective glass 4 to provide sealing and protection for the camera body 5. The camera body 5 has good stability. Then, the externally designed lens protective cover 3 and the air and water channel connector 301 are used to ensure that the lens position of the camera body 5 is provided with a cleaning function. The cleaning effect is good, and dust is prevented from sticking to the lens position of the camera body 5 to affect the work and taking pictures.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
