[0027] 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.

[0028] See also Figure 1-6 A protective device for an instrument valve group includes a protective box 1, in which an instrument valve group body 2 is installed. The instrument valve group body 2 is installed inside the protective box 1, which can effectively provide protection for the surface of the instrument valve group body 2 and reduce the probability of the instrument valve group body 2 being damaged from the outside.

[0029] The instrument valve group body 2 in the attached drawings is only for style reference and is not a specific size standard. The instrument valve group body 2 is an existing mechanism and is not the object of protection in this application. Therefore, the internal structure and working principle of the instrument valve group body 2 are not described in detail.

[0030] The inner bottom wall of the protection box 1 is fixedly connected with a fixing seat 9 , the upper surface of the fixing seat 9 is fixedly connected with two sets of fixing components 10 , and the outer surface of the instrument valve group body 2 is fixedly connected above the fixing seat 9 through the two sets of fixing components 10 .

[0031] By providing the fixing seat 9 and the fixing assembly 10 , the instrument valve group body 2 can be installed in the protection box 1 more stably, thereby improving the protection effect of the device on the instrument valve group body 2 .

[0032] An observation window 3 is installed on the front of the protection box 1 . The observation window 3 can be convenient for the staff to observe the data displayed on the instrument panel on the surface of the instrument valve group body 2 through the observation window 3 .

[0033] A wiping mechanism 4 is provided outside the observation window 3 , and the wiping mechanism 4 includes a reciprocating screw 401 rotatably sleeved on the front side of the protection box 1 , and a cleaning block 402 is threadedly connected to the outer surface of the reciprocating screw 401 .

A side of the cleaning block 402 close to the observation window 3 is provided with evenly distributed cleaning soft bristles.

[0035] By setting the guide rod 403, when the reciprocating screw 401 rotates, the two sides of the cleaning block 402 can move back and forth along the reciprocating screw 401 and the guide rod 403 respectively, so that the outer surface of the observation window 3 can be continuously cleaned by the cleaning soft hair on the surface of the cleaning block 402, thereby preventing a large amount of dust from accumulating on the surface of the observation window 3, which is conducive to observing the working condition of the instrument valve group body 2.

[0036] A heat dissipation mechanism 5 is provided inside the protection box 1 , a transmission mechanism 6 is provided between the wiping mechanism 4 and the heat dissipation mechanism 5 , and the heat dissipation mechanism 5 includes a servo motor 501 fixedly connected to the inner wall of the protection box 1 , and a first fan 502 is fixedly connected to the output shaft end of the servo motor 501 .

[0037] When the servo motor 501 is driven to work, it will drive the first fan 502 to rotate. When the first fan 502 rotates, it will blow air toward the back of the protection box 1, accelerating the rate of air circulation inside and outside the protection box 1, which is beneficial to the heat dissipation inside the protection box 1. While providing protection for the instrument valve group body 2, it can prevent the instrument valve group body 2 from working in a high temperature environment, which is beneficial to the normal operation of the instrument valve group body 2.

[0038] The inner wall of the protection box 1 is rotatably sleeved with a rotating rod 503, one end of which is fixedly connected to a second fan 504. When the rotating rod 503 rotates, the second fan 504 is driven to rotate, and wind is generated when the second fan 504 rotates.

[0039] The inner wall of the protection box 1 is fixedly connected with a bracket 505 , the outer surface of the rotating rod 503 is rotatably connected to the inside of the bracket 505 , and the first fan 502 and the second fan 504 are both located inside the protection box 1 .

[0040] The bracket 505 can make the rotating rod 503 more stable when rotating, which is beneficial to the air circulation inside the protective box 1.

[0041] First heat dissipation openings 506 are provided on both sides of the outer surface of the protection box 1 . A rear cover 7 is installed on the back of the protection box 1 . A second heat dissipation opening 8 is provided on the outer surface of the rear cover 7 .

[0042] By installing the back cover 7 on the back of the protection box 1, the front of the protection box 1 can be fixed and sealed, which is beneficial to the protection of the instrument valve group body 2. By setting the first heat dissipation port 506 and the second heat dissipation port 8, the circulation of air inside and outside the protection box 1 can be ensured, thereby facilitating the heat dissipation of the instrument valve group body 2.

[0043] The transmission mechanism 6 includes a first sprocket 601 and a second sprocket 602. The inner wall of the first sprocket 601 is fixedly connected to the outer surface of the output shaft of the servo motor 501. The inner wall of the second sprocket 602 is fixedly connected to the outer surface of the rotating rod 503. A chain 603 is provided inside the protective box 1. The first sprocket 601 is transmission-connected to the second sprocket 602 via the chain 603.

[0044] When the servo motor 501 is started, it can drive the first fan 502 and the first sprocket 601 to rotate. By setting the second sprocket 602 and the chain 603, the rotating rod 503 and the second fan 504 can be rotated, so that the first fan 502 and the second fan 504 can rotate and blow air at the same time.

[0045] The blown wind will carry the air inside the protection box 1 to the outside through the second heat dissipation port 8, accelerate the rate of air exchange inside and outside the protection box 1, improve the heat dissipation effect inside the protection box 1, and avoid the instrument valve group body 2 working in a high temperature environment, which is more practical.

[0046] The end of the rotating rod 503 away from the second fan 504 passes through the protective box 1 and is fixedly connected to the first bevel gear 604. The rotating shaft end of the reciprocating screw 401 is fixedly connected to the second bevel gear 605 meshing with the first bevel gear 604. The front side of the protective box 1 is fixedly connected to the protective shell 404. The first bevel gear 604 and the second bevel gear 605 are both located inside the protective shell 404.

[0047] When the rotating rod 503 rotates, the reciprocating screw 401 can be driven to rotate through the first bevel gear 604 and the second bevel gear 605, so that the cleaning block 402 can continuously wipe and clean the surface of the observation window 3 to prevent a large amount of dust from accumulating on the surface of the observation window 3, thereby avoiding affecting the work of observing the instrument panel data on the surface of the instrument valve group body 2 through the observation window 3.

[0048] Through the above description, when the servo motor 501 is driven to work, on the one hand, the rate of air circulation inside and outside the protective box 1 can be accelerated, and on the other hand, the surface of the observation window 3 can be continuously cleaned, thereby achieving the effect of facilitating the use of the instrument valve group while ensuring the protection effect of the instrument valve group body 2.

[0049] The specific implementation process of the utility model is as follows: when in use, the rear cover 7 is opened, and the instrument valve group body 2 is installed inside the protective box 1 through the two fixing components 10 inside the protective box 1, and then the instrument valve group body 2 is connected to the external equipment through the instrument valve group body 2, so that the instrument valve group body 2 can work normally, so that the surrounding of the instrument valve group body 2 can be protected, and the probability of the instrument valve group body 2 being damaged from the outside can be reduced. When the instrument valve group body 2 is working, the servo motor 501 can be driven to work. When the servo motor 501 is working, it will drive the first fan 502 to rotate, and the first sprocket 601 will also rotate. The chain 603 set will drive the rotating rod 503 and the second sprocket 602 to rotate. When the rotating rod 503 rotates, it will drive the second fan 504 to rotate. The first fan 502 and the second fan 504 rotate at the same time and generate wind, which can accelerate the circulation of air inside and outside the protective box 1 and prevent the instrument valve group body 2 from working in a high temperature environment. At the same time, the rotation of the rotating rod 503 will also drive the first bevel gear 604 to rotate. By setting the second bevel gear 605 meshing with the first bevel gear 604, the reciprocating screw rod 401 can be rotated. When the servo motor 501 rotates, the cleaning block 402 can be reciprocated along the reciprocating screw rod 401 and the guide rod 403, so that the cleaning soft hair on the surface of the cleaning block 402 can continuously clean the surface of the observation window 3, preventing a large amount of dust from accumulating on the surface of the observation window 3, and avoiding affecting the work of observing the instrument panel data on the surface of the instrument valve group body 2 through the observation window 3.
