[0002] The role of monitoring equipment in daily life is becoming more and more important. The internal components of existing monitoring equipment are easily affected by external factors, which may affect the monitoring effect or reduce the service life of the monitoring equipment. For example, when a fire hazard occurs, it is generally accompanied by a lot of smoke and high temperature. The monitoring equipment is easily affected and stops working, making it impossible to better monitor the environment, which reduces the role of monitoring, fails to provide good feedback on dangerous situations, and is inconvenient to use.

[0020] 3. Beneficial Effects

[0021] Compared with the prior art, the present invention guides the water flow through the water flow channel on the first ring sleeve to clean the outer surface of the transparent cover, and guides the air flow through the blowing channel on the second ring sleeve to disperse the smoke and dust around the transparent cover, keeping the monitored subject in a clear monitored state through the transparent cover, achieving favorable observation of dangerous situations, improving the monitoring effect, and avoiding interference and damage to the monitored subject.

[0022] The water flow is also guided through the water flow channel, so that the water is sprayed out from the water outlet and acts on the outer surface of the transparent cover, thereby cleaning the dirt on the outer surface of the transparent cover, thereby achieving the cleaning of the transparent cover and avoiding the transparent cover being attached with dirt, which causes the monitoring line of sight of the monitoring subject to be blocked, thereby improving the monitoring effect of the monitoring subject and facilitating the observation of dangerous situations. By setting the water wheel in the water flow channel, when the water flows through the water wheel, it drives the rotation of the water wheel, and because the water wheel is fixedly connected to the fan, the rotation of the fan is driven by the action of water, and there is no need to install an additional power supply, thereby promoting the simultaneous generation of airflow and water flow, achieving the dispersion of smoke, which is conducive to the diffusion of water vapor in the smoke, improving the purification of the smoke, and ensuring that the monitoring subject has a clear observation line of sight.

[0023] Furthermore, by opening an air blowing channel and placing the air outlet directly below the transparent cover, the airflow is guided to the bottom of the transparent cover, which is beneficial to dispersing the smoke below the transparent cover. In addition, the airflow disperses the water vapor after the water flow is sprayed, which causes the water vapor to diffuse to the surroundings, thereby further effectively handling the smoke and fire. In the event of a fire disaster, it is convenient for the monitoring subject to observe the dangerous situation and to handle the smoke in the monitoring area, thereby improving the monitoring effect and the smoke treatment effect.

[0045] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] like Figure 1-Figure 6 As shown, a monitoring device with a protective function for intelligent fire protection includes a monitoring body 1 and a shell 2 for fixing the monitoring body 1, an opening is provided on the shell 2 at the monitoring end of the monitoring body 1, a transparent cover 3 is provided in the opening, a temperature sensor 4 is also fixedly provided on the outer wall of the shell 2, a first ring sleeve 5 is provided around the transparent cover 3 on the shell 2, a water flow channel 51 extending toward the outer surface of the transparent cover 3 is provided in the first ring sleeve 5, a second ring sleeve 6 is provided around the first ring sleeve 5 on the shell 2, a blowing channel 61 extending toward the bottom of the transparent cover 3 is provided in the second ring sleeve 6, and a surface cleaning mechanism 7 for removing dust contaminated on the surface of the transparent cover 3 is also provided on the outer surface of the transparent cover 3.

[0047] When using the fire fighting equipment, the monitoring body 1 is fixed in the housing 2, the housing 2 is fixed at the position to be monitored, the monitoring end of the monitoring body 1 is facing the area to be monitored through the transparent cover 3, under normal conditions, the temperature sensor 4 senses that the temperature is within the normal range, and the monitoring body 1 works normally. When a fire occurs in the monitoring area and a large amount of smoke appears, the temperature of the monitoring area rises, and the temperature sensor 4 senses that the temperature exceeds the normal range, and then water is transported to the water flow channel 51 in the first ring sleeve 5, and the water is sprayed along the water flow channel 51 to the outer surface of the transparent cover 3, and the outer surface of the transparent cover 3 is The smoke and dust on the surface can be cleaned to prevent the transparent cover 3 from being blocked by the smoke and ash, resulting in the situation that the monitoring line of sight is not blocked. Along with the spraying of water flow, the surface cleaning mechanism 7 automatically cleans the outer surface of the transparent cover 3 under the water pressure to remove the dirt attached to the outer surface of the transparent cover 3. In the process of water spraying, the blowing channel 61 in the second ring sleeve 6 will blow away the smoke and dust around the transparent cover 3 without affecting the observation of the monitoring subject 1, and will blow the water vapor to the surroundings, thereby improving the dust reduction and smoke removal effect around the monitoring subject 1, keeping the monitoring subject 1 in a normal and clear monitoring line of sight, being able to well feedback the dangerous situation, and being more convenient to use.

[0048] like Figure 4 and Figure 5 As shown, the outer shell 2 has a cavity 21 for water to enter, the outer wall of the first ring sleeve 5 has a water inlet 511 connected to the cavity 21 and the water flow channel 51, the inner wall of the first ring sleeve 5 has a water outlet 512 connected to the water flow channel 51, and the top of the outer shell 2 is provided with a pipe joint 22 connected to the cavity 21.

[0049] When the temperature sensor 4 senses that the temperature exceeds the normal range, it transmits a signal to the electric control valve of the external water pipe. The water pipe is connected to the shell 2 through the pipe joint 22, and the water flows into the cavity 21 of the shell 2, and then enters the water flow channel 51 through the water inlet 511 of the first ring sleeve 5, and reaches the water outlet 512 along the water flow channel 51 and is sprayed out, acting on the outer surface of the transparent cover 3, thereby cleaning the outer surface of the transparent cover 3.

[0050] like Figure 4-Figure 6 As shown, the lower extension end of the blowing channel 61 in the second ring sleeve 6 has an air outlet 611 connected thereto, and the air outlet 611 is oriented directly below the transparent cover 3. An annular fan 62 is provided around the second ring sleeve 6 in the blowing channel 61, and the fan 62 can rotate in the blowing channel 61. A bearing 621 is connected between the fan 62 and the outer shell 2.

[0051] When the fan 62 rotates in the blowing channel 61, the airflow is discharged through the air outlet 611 along the blowing channel 61. Since the air outlet 611 is directed directly below the transparent cover 3, the blowing of the airflow disperses the smoke below the transparent cover 3, so that the monitoring line of sight of the monitoring body 1 is not blocked, and the contact between the smoke and the outer surface of the transparent cover 3 is further avoided, reducing the generation of dirt on the outer surface of the transparent cover 3, which is beneficial to the monitoring of the monitoring body 1.

[0052] like Figure 5 , Figure 6 and Fig. 9 As shown, a ring-shaped water wheel 52 is provided at the lower end of the outer shell 2 and is located in the cavity 21 around the first ring sleeve 5. The water wheel 52 is rotatably arranged on the outer shell 2. The outer wall of the outer shell 2 is provided with a surrounding opening for rotatably installing the water wheel 52. The blades on the water wheel 52 extending into the cavity 21 are deflected in a direction. The rotation axis of the water wheel 52 is parallel to and coaxial with the rotation axis of the fan 62. A collar 53 is fixedly provided on the outer ring of the fan 62. A connecting rod 531 is fixedly provided between the collar 53 and the outer ring of the water wheel 52.

[0053] When the water flows along the water flow channel 51, the water flows through the water wheel 52. Since the water wheel 52 is rotatably arranged on the outer shell 2, and the blades of the water wheel 52 are deflected in the water flow channel 51, the water wheel 52 will drive it to rotate around the first ring sleeve 5 when passing through the water wheel 52. Since the water wheel 52 and the fan 62 are fixedly connected, the rotation of the water wheel 52 drives the rotation of the fan 62, and the rotation of the fan 62 drives the flow of air. The airflow flows out from the starting port along the blowing channel 61, forming an effect of blowing air at the same time as the water flow, which effectively treats the smoke.

[0054] like Figure 5 and Fig. 9 As shown, the inner circle of the fan 62 has spoiler blades 622 extending to the lower half of the blowing channel 61.

[0055] When the fan 62 rotates, since the inner ring of the fan 62 has the spoiler blades 622 extending to the lower half of the blowing channel 61, the airflow can follow the blowing channel 61 and be discharged from the air outlet 611, ensuring that the airflow can be discharged from the air outlet 611 normally, avoiding the situation where the fan 62 is unable to lead out the airflow or the airflow discharge volume is too low at the air inlet of the blowing channel 61, increasing the air volume, which is beneficial to the dispersion of the smoke under the transparent cover 3 by the airflow.

[0056] like Figure 7 As shown, the top end of the second ring sleeve 6 is provided with an end cover 63 fixed thereto around the outer shell 2 , and the end cover 63 is provided with an air inlet 631 communicating with the blowing channel 61 .

[0057] When the fan 62 rotates, since the end cover 63 at the top of the second ring sleeve 6 is provided with an air inlet 631 , the fan 62 can guide the external airflow into the blowing channel 61 , thereby improving the airflow guiding effect of the fan 62 .

[0058] like Figure 8 and Fig.10 As shown, the surface cleaning mechanism 7 is provided with a first arc piece 71, the transparent cover 3 is an arc-shaped structure, the first arc piece 71 surrounds the outer surface of the transparent cover 3, the inner wall of the first arc piece 71 contacts the outer surface of the transparent cover 3, and the first arc piece 71 can move on the surface of the transparent cover 3. When the first arc piece 71 is at the edge of the transparent cover 3, the water outlet 512 of the water channel 51 is in a state of being shielded by the first arc piece 71.

[0059] When water flows out from the water outlet 512, since under normal conditions, the first arc piece 71 is on the surface of the transparent cover 3 and blocks the position of the water outlet 512, as the water flows out, under water pressure, the first arc piece 71 is pushed to move along the surface of the transparent cover 3. Since the inner wall of the first arc piece 71 contacts the outer surface of the transparent cover 3, the movement of the first arc piece 71 will scrape off the dirt on the outer surface of the transparent cover 3, and under the impact of the water flow on the transparent cover 3, the outer surface of the transparent cover 3 is cleaned, which is beneficial to the effective monitoring of the monitoring body 1 and avoids the line of sight being blocked by dirt.

[0060] like Figure 8 As shown, the surface cleaning mechanism 7 is further provided with a second arc piece 73, which is symmetrically arranged on the outer surface of the transparent cover 3 relative to the first arc piece 71. When water flows out of the water outlet 512, the first arc piece 71 and the second arc piece 73 are in a relatively active state on the surface of the transparent cover 3.

[0061] When the water flows out from the water outlet 512, the second arc piece 73 is also pushed by the water pressure to move along the outer surface of the transparent cover 3 until the first arc piece 71 and the second arc piece 73 are in contact. The first arc piece 71 and the second arc piece 73 are in the middle position of the transparent cover 3, and the dirt on the outer surface of the transparent cover 3 is scraped off. The continuous spraying of water further rinses the outer surface of the transparent cover 3, and is conducive to the dispersion of water vapor by the airflow, thereby achieving purification of the flue gas.

[0062] like Figure 8 and Fig.10 As shown, the inner walls of the first arc piece 71 and the second arc piece 73 that are in contact with the outer surface of the transparent cover 3 are provided with a brush 711 for brushing off dirt on the outer surface of the transparent cover 3 .

[0063] When the first arc piece 71 and the second arc piece 73 move along the outer surface of the transparent cover 3, since the inner walls of the first arc piece 71 and the second arc piece 73 have brushes 711, the first arc piece 71 and the second arc piece 73 can scrape off the dirt on the outer surface of the transparent cover 3, and the setting of the brushes 711 will not scratch the outer surface of the transparent cover 3, thereby ensuring a clear observation line of sight for the monitoring body 1.

[0064] like Figure 8 and Fig.10 As shown, a return spring 74 is connected between the first arc piece 71 and the second arc piece 73. When the first arc piece 71 and the second arc piece 73 are respectively located on both sides of the transparent cover 3, the return spring 74 is in a normal state.

[0065] When the first arc piece 71 and the second arc piece 73 come into contact under the pressure of the water flow, the return spring 74 is in a compressed state. When the water flow stops, the return spring 74 returns to a normal state, and the first arc piece 71 and the second arc piece 73 return to their original positions to continue to shield the water outlet 512, thereby preventing water droplets from dripping along the water outlet 512 when there is no danger, and also ensuring that the first arc piece 71 and the second arc piece 73 continue to clean the outer surface of the transparent cover 3 under the next water flow impact.

[0066] like Figure 8 and Fig.10 As shown, guide rods 72 for guiding the moving directions of the first arc piece 71 and the second arc piece 73 are provided on the first ring sleeve 5 and on both sides of the transparent cover 3. The guide rods 72 are in an arc-shaped structure and are coaxial with the transparent cover 3. Guide openings sleeved on the guide rods 72 are provided on the first arc piece 71 and the second arc piece 73.

[0067] When the first arc piece 71 and the second arc piece 73 move along the surface of the transparent cover 3 , the guide rod 72 guides them, and prompts the brushes 711 on the first arc piece 71 and the second arc piece 73 to move along the surface of the transparent cover 3 .

[0068] like Figure 8 and Fig.10 As shown, there are two return springs 74 , and the two return springs 74 are respectively located on one side of the first arc piece 71 and the second arc piece 73 close to each guide rod 72 .

[0069] When the first arc piece 71 and the second arc piece 73 move along the surface of the transparent cover 3, the return spring 74 returns the first arc piece 71 and the second arc piece 73 to their original positions. The return spring 74 is arranged on both sides of the transparent cover 3 so as not to hinder the monitoring body 1 from observing the outside through the transparent cover 3.

[0070] In this embodiment, the water flow is guided by the water flow channel 51 on the first ring sleeve 5, so that the outer surface of the transparent cover 3 is cleaned, and the air flow is guided by the blowing channel 61 on the second ring sleeve 6, so that the smoke and dust around the transparent cover 3 are dispersed, so that the monitoring body 1 is kept in a clear monitoring state through the transparent cover 3, thereby improving the monitoring effect and avoiding interference and damage to the monitoring body 1.

[0071] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
