The technical solution disclosed in the patent document is as follows: a fan is arranged at the bottom of the detection device housing, an inner cavity wrapped with a heat preservation layer is arranged above the fan, a heater is arranged at the bottom of the inner cavity, and an air outlet is arranged at the top of the inner cavity. However, the above solution still has the problem that the infrared signal is blocked by dust and stains when collecting. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a temperature sensing detector detection device for building fire protection facilities. One technical problem solved is that the signal of the existing mechanism is blocked by dust and stains when collecting infrared signals.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A heat detector detection device for building fire protection facilities includes a heat detector body, a rotating block is arranged at the top of the heat detector body, a series rod is fixedly connected to the side of the rotating block, a wiping cotton is fixedly connected to the bottom end of the series rod, an infrared signal receiver body is fixedly connected to the middle of the bottom end of the heat detector body, the wiping cotton rotates along the central axis of the heat detector body, and the wiping cotton is used to wipe the outer surface of the infrared signal receiver body. This can prevent dust and stains from affecting infrared sensing.

[0007] As a further improvement of the utility model, the top of the rotating block is fixedly connected with a motor, and the inner side of the series rod is fixedly connected with a sliding plate and a triangular abutment block, so that the wiping cotton can move in a circular motion.

[0008] As a further improvement of the utility model, a sliding hole is provided at the top of the temperature detector body, a sliding groove is provided at the side of the temperature detector body, and the rotating block and the sliding plate are slidably connected inside the sliding hole and the sliding groove, respectively, so as to support the wiping cotton and increase the force range.

[0009] As a further improvement of the utility model, a liquid storage ring is fixedly connected to the side of the temperature sensor body, a liquid leakage hole is opened at the bottom of the liquid storage ring, a hollow sliding plate is slidably connected inside the top surface of the liquid storage ring, and a spring 1 and a telescopic rod are fixedly connected to the top of the hollow sliding plate. Thus, the alcohol stored in the liquid storage ring can flow to the top of the wiping cotton.

[0010] As a further improvement of the utility model, the spring 1 is located inside the telescopic rod, the spring 1 and the top of the telescopic rod are fixedly connected with a pressing block, the inner wall of the hollow sliding plate is fixedly connected with a spring 2, the other end of the spring 2 is fixedly connected to the liquid storage ring, the bottom end of the hollow sliding plate is fixedly connected with a connecting rod, and the bottom end of the connecting rod is fixedly connected with a shielding plate. Therefore, alcohol can be injected into the top of the wiping cotton during its rotation.

[0011] As a further improvement of the utility model, the shielding plate is fitted with the inner wall of the liquid storage ring, so that the leakage hole can be better sealed.

[0012] As a further improvement of the present invention, the bottom material of the infrared signal receiver body is made of filter material, thereby effectively reducing the influence of visible light on the infrared sensor signal.

[0013] As a further improvement of the utility model, the wiping cotton moves in a circular motion and the top of the wiping cotton contacts the bottom surface of the infrared signal receiver body in each circular motion, so that the wiping frequency of the wiping cotton on the bottom of the infrared signal receiver body can be controlled according to the motor speed.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. After the rotating block, the series rod and the wiping cotton are connected, the motor is started to rotate the rotating block fixedly connected to the motor output shaft. Since the other end of the series rod fixedly connected to the side of the rotating block is fixedly connected to the wiping cotton, the rotation of the rotating block will drive the wiping cotton to rotate along the center. Since the circular motion trajectory of the wiping cotton will pass through the bottom of the infrared signal receiver body each time, the dust and stains at the bottom of the infrared signal receiver body can be wiped. Wiping can remove stains and dust on the surface of the infrared signal receiver body, so that the infrared signal receiver body can better receive infrared signals and improve the sensitivity and accuracy of reception. Wiping can reduce misjudgment or reception of interference signals, and improve the reliability and stability of the system. In addition, dust and stains may cause poor heat dissipation of the infrared signal receiver body. By continuous wiping, the infrared signal receiver body can be kept clean, avoiding overheating and damage caused by accumulated stains, and extending its service life.

[0016] 2. Through the triangular contact block, liquid storage ring, leakage hole and pressing block, the triangular contact block moves under the drive of the motor rotation. Since the pressing block is set on the movement trajectory of the triangular contact block, when the triangular contact block touches the pressing block under the rotation of the motor, the shielding plate blocking the top surface of the leakage hole will open, so that the alcohol inside the liquid storage ring will flow to the top of the wiping cotton, so as to achieve the effect of wiping the surface of the filter with alcohol. There may be stains and grease attached to the surface of the filter. Using alcohol to wipe can effectively remove these stains and grease, so that the filter can be restored to a clean state. If there are stains and grease on the surface of the filter, it will affect the light transmission effect, thereby affecting the working effect of the filter. Wiping can remove these substances that affect the light transmittance and improve the light transmittance of the filter, so that the infrared signal can be better received.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0025] 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.

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] As shown in the figure, a temperature sensing detector detection device for building fire protection facilities includes a motor 201, a rotating block 202, a series rod 203, a sliding plate 204, a triangular abutment block 205 and a wiping cotton 206.

[0028] The motor 201 is started, and the output shaft of the motor 201 is fixedly connected to the rotating block 202, thereby driving the rotating block 202 to rotate. Since the serial rod 203 is fixedly connected to the side of the rotating block 202, and the bottom end of the serial rod 203 is fixedly connected with the wiping cotton 206, the rotation of the rotating block 202 will drive the wiping cotton 206 to perform a circular motion. Since the wiping cotton 206 is set in a special shape, it fits perfectly with the outside of the temperature detector body 101, and the wiping cotton 206 will touch the bottom end of the infrared signal receiver body 104 during the rotation process, thereby achieving the effect of wiping the filter on the bottom end surface of the infrared signal receiver body 104 by the wiping cotton 206. Wiping can remove stains and dust on the surface of the infrared signal receiver body 104, so that the infrared signal receiver body 104 can better receive infrared signals and improve the sensitivity and accuracy of reception. Wiping can reduce misjudgment or receiving interference signals, and improve the reliability and stability of the system.

[0029] Furthermore, before installation, alcohol is completely filled into the liquid storage ring 301, and the rotation of the rotating block 202 will drive the series rod 203 to rotate. Since the triangular interference block 205 is fixedly connected to the side of the series rod 203, the rotation of the rotating block 202 will drive the triangular interference block 205 to perform annular motion. Since the pressing block 303 located at the top of the liquid storage ring 301 is set on the annular motion path of the triangular interference block 205, when the triangular interference block 205 contacts the pressing block 303, due to the triangular interference block 205 and the pressing block 303, The inclined surfaces of the triangular contact block 205 are complementary to each other, so that the triangular contact block 205 will generate a forward and downward thrust on the pressing block 303. The downward thrust can make the pressing block 303 move downward to press the spring 1 304 and the telescopic rod 305, so that the pressing block 303 will not affect the movement of the triangular contact block 205. When the triangular contact block 205 is away from the pressing block 303, the pressing block 303 is reset by the rebound of the telescopic rod 305. The rebound of the telescopic rod 305 can simplify the mechanical structure and reduce the need for complex power sources and control systems. This method can reduce costs and maintenance complexity. Moreover, the rebound of the telescopic rod 305 can improve the reliability of the system because it does not rely on the supply of external power or other energy. This method can operate more reliably under conditions where there are not often staff inspections.

[0030] Furthermore, the forward thrust generated by the triangular friction block 205 on the pressing block 303 can drive the hollow sliding plate 306 fixedly connected to the bottom of the spring 1 304 to slide forward. Since the baffle plate 309 fixedly connected to the bottom of the hollow sliding plate 306 by the connecting rod 308 blocks the leakage hole 302, when the hollow sliding plate 306 moves, the baffle plate 309 will no longer block the leakage hole 302. At this time, since the movement is triggered by the triangular friction block 205, and the triangular friction block 205 and The wiping cotton 206 is in the same plane, so that the alcohol inside the liquid storage ring 301 flows into the wiping cotton 206. When the triangular abutment block 205 is away from the pressing block 303, the hollow sliding plate 306 will be restored under the rebound of the spring 2 307, so that the shielding plate 309 blocks the leakage hole 302 again. The filter surface is wiped by alcohol. There may be stains and grease attached to the filter surface. Wiping with alcohol can effectively remove these stains and grease, so that the filter is restored to a clean state. The automatic injection of alcohol can accurately control the injection amount and speed of alcohol, ensuring that the appropriate amount of alcohol can be obtained each time the wiping cotton 206 passes, avoiding excessive or insufficient situations. And the automatic injection of alcohol can improve production efficiency, save labor costs, and reduce the time and workload of manual operation.

[0031] The advantages of the utility model are: 1) Wiping the dust and stains at the bottom of the infrared signal receiver body 104 can remove the stains and dust on the surface of the infrared signal receiver body 104, so that the infrared signal receiver body 104 can better receive infrared signals and improve the sensitivity and accuracy of reception. 2) Wiping the surface of the filter with alcohol can remove those substances that affect the light transmittance, improve the light transmittance of the filter, and thus better receive infrared signals. 3) The rebound of the telescopic rod 305 can simplify the mechanical structure and reduce the need for complex power sources and control systems. This method can reduce costs and maintenance complexity. 4) Automated alcohol injection can accurately control the amount and speed of alcohol injection, ensuring that the right amount of alcohol is obtained each time the wiping cotton 206 passes through, avoiding excessive or insufficient situations.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
