[0023] The driving assembly 7 includes a lead screw 701 and a nut 702 . The lead screw 701 is rotatably connected to two ends of the interior of the vertical plate 4 . The surface of the lead screw 701 is threadedly connected with the nut 702 . The lead screws 701 are connected via a synchronous wheel 703 .
[0024] The push-pull assembly 8 includes a sliding base 801 and a movable base 802. The sliding base 801 is slidably connected to the surface of the side frame 5. The sliding base 801 and the movable base 802 are connected by a first connecting rod 803. A second connecting rod 804 is provided on one side of the first connecting rod 803. The upper and lower ends of the second connecting rod 804 are rotatably connected to the nut 702 and the surface of the movable base 802 respectively.
[0025] In this embodiment, Figure 3 As shown, the surface of the vertical plate 4 is connected to the servo motor 704 by bolts, and the output end of the servo motor 704 is welded to the surface of the lead screw 701 on one side, and the second connecting rod 804 forms a lifting structure on the surface of the vertical plate 4 through the nut 702; the movement of the push-pull component 8 is realized by the transmission structure of the lead screw 701 and the nut 702, and the push-pull component 8 is used to fold the protective cover 6. The push-pull component 8 is provided with two groups. Pushing at both ends of the protective cover 6 at the same time can ensure that the protective cover 6 remains balanced during the folding process, avoiding uneven deformation or tearing that may be caused by folding one side too fast or too slow.
[0026] In this embodiment, Figure 1 and Figure 2 As shown, the side frame 5 is arc-shaped, and arc-shaped slide grooves are respectively provided on the surface of the side frame 5, and the first connecting rod 803 is slidably connected to the slide groove on the surface of the side frame 5 through the second connecting rod 804; the protective cover 6 currently used for waterproofing is set on the top of the equipment, and is usually sloped to achieve effective drainage effect. The sliding base 801 slides along the arc-shaped slide groove on the surface of the side frame 5, and the arc-shaped structure of the side frame 5 can perfectly match the unfolding area of the protective cover 6, so that the protective cover 6 can fit tightly on the surface of the side frame 5 when unfolded, maximally covering the protection area and providing more effective protection.
[0027] In this embodiment, Figure 4As shown, a retractable shaft is provided inside the first connecting rod 803, and the upper and lower ends of the first connecting rod 803 are rotatably connected to the surfaces of the sliding base 801 and the movable base 802 respectively; when the second connecting rod 804 is lifted or lowered under the transmission structure of the nut 702, it will correspondingly drive the movable base 802 below and the first connecting rod 803 to be transmitted upward, and since one end of the first connecting rod 803 is connected to the sliding base 801, the sliding base 801 is correspondingly made to slide in the side frame 5, and the front end of the protective cover 6 is further unfolded while sliding, and when the nut 702 is continuously transmitted, the first connecting rod 803 and the second connecting rod 804 will turn respectively, and the telescopic structure of the first connecting rod 803 can ensure the unfolding of the protective cover 6.
[0028] In this embodiment, Figure 1 and Figure 2 As shown, one end of the protective cover 6 is glued to the surface of the vertical plate 4, and the other end of the protective cover 6 is connected to the sliding base 801 on both sides by twisting steel wires, and the protective cover 6 moves in an opening and closing state above the detector 3 through the sliding base 801; the protective cover 6 is made of polytetrafluoroethylene, which is lightweight and corrosion-resistant. The arc-shaped structure of the protective cover 6 after unfolding provides a wider field of view for the detector 3 below, and will not affect the monitoring process of the detector 3 while achieving the protective effect. The arc-shaped structure has better structural stability, which helps to reduce wind resistance and improve the stability of the cover during use.
[0029] In this embodiment, Figure 1 and Figure 2 As shown, a rain sensor is provided on the outer top wall of the detector 3, and the rain sensor is electrically connected to the controller 2 through a servo motor 704; the rain sensor (model JD-Y1.0) uses the capacitance principle to detect the moisture on the surface of an object. When rain covers the sensor surface, it changes the capacitance of the capacitor, thereby generating a detection signal which is transmitted to the controller 2, and then the servo motor 704 is driven by the controller 2 to realize the opening of the protective cover 6. The protective cover 6 can be automatically opened without human control, thereby avoiding the problem that the personnel cannot make emergency treatment of the detector 3 in time due to excessive rainfall, and also avoiding the problem that the detector 3 is damaged by rain erosion.
[0030] The use method and advantages of the utility model: When the waterproof flame detector assembly is used, the working process is as follows:
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the device is fixed by the mounting base 1 and connected with the other units for the explosion suppression system. Under normal conditions, the protective cover 6 is folded on the surface of the vertical plate 4. When it rains, the rain sensor on the surface of the detector 3 detects that there is moisture on its surface. When the rain covers the surface of the sensor, it changes the capacitance of the capacitor, thereby generating a detection signal that is transmitted to the controller 2. Then the controller 2 drives the servo motor 704, and the lead screw 701 rotates. Under the transmission of the synchronous wheel 703, another set of lead screws 701 rotates, and then the two nuts 702 are respectively transmitted on the surface of the lead screw 701, and the second connecting rod 804 rises with the nut 702, which correspondingly drives the movable base 802 below and the first connecting rod 803 to transmit upward. The up and down movement of the first connecting rod 803 will cause the sliding base 801 to slide in the side frame 5, and the sliding path of the sliding base 801 is consistent with the sliding groove on the surface of the side frame 5. During the continuous sliding process, the sliding base 801 will pull the protective cover 6 to unfold at the same time. While the nut 702 is continuously transmitting and the sliding base 801 is sliding, the first connecting rod 803 and the second connecting rod 804 will turn respectively, and the first connecting rod 803 will then stretch. In rainy weather, the unfolding of the protective cover 6 effectively protects the detector 3 to avoid damage to the equipment due to excessive rainfall. At the same time, its arc-shaped structure provides a wider field of view for the detector 3 below, and will not affect the monitoring process of the detector 3 while achieving the protection effect.
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
