[0002] A certain amount of toxic and harmful gases are often produced during the processing of chemical raw materials. These gases not only fail to meet environmental emission requirements, but also cause serious damage to the health of workshop workers. Therefore, environmental safety testing in chemical plants is particularly important.

[0003] Existing environmental detection alarm devices are generally fixed to the installation column in the detection area and are generally not movable and transportable, which has limitations in use. In the environmental detection alarm device disclosed in the existing utility model patent with publication number CN213040239U, it uses a movable body to fix the detection alarm on the lifting mechanism. Although it can be portable and the detection alarm can be lifted to a certain height for detection, in complex workshop environments, many detection areas are relatively restricted and cannot be passed by mobile bodies. In addition, the lifting height of the detection alarm is very limited. The detection alarm is also fixed on the mobile body and cannot be removed. This device is not suitable for narrow detection areas or high detection heights. Utility Model Content

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0025] like Figures 1-4 As shown, the present invention provides an environmental detection and alarm device for a chemical plant, comprising a mobile lifting frame and a detection alarm 42. The mobile lifting frame comprises a traveling base 1 and a lifting rod 2, which is vertically mounted on the traveling base 1. The traveling base 1 is equipped with electric running wheels at the bottom to facilitate movement of the device. The lifting rod 2 can be a hydraulic lifting rod 2.

[0026] A fixing seat 3 is provided at the top of the piston rod of the lifting rod 2, and an equipment box 4 is provided above the fixing seat 3. The bottom of the equipment box 4 can be detachably mounted on the fixing seat 3. Specifically, a groove 30 is provided on the top surface of the fixing seat 3, and an inverted T-shaped connecting block 8 is fixed to the bottom of the equipment box 4. The connecting block 8 is clamped in the groove 30. A through-hole 31 is horizontally penetrated through the side of the fixing seat 3 and connected to the groove 30. A clamping block 32 is provided in the through-hole 31 for horizontal sliding. One end of the clamping block 32 cooperates with the horizontal part of the connecting block 8. The clamping block 32 is clamped above the two ends of the horizontal part of the connecting block 8, thereby locking the connecting block 8. The other end of the clamping block 32 is horizontally fixed to one end of a pull rod 33, and the other end of the pull rod 33 extends outward through the through-hole 31. A spring 34 is sleeved on the pull rod 33 in the through-hole 31. One end of the spring 34 abuts against the clamping block 32, and the other end abuts against the inner wall of the outer opening of the through-hole 31. A limiting baffle 331 is fixedly provided at the end of the pull rod 33 outside the through hole 31 . The limiting baffle 331 is used to limit the movement of the pull rod 33 and the clamping block 32 .

[0027] When the equipment box 4 needs to be removed from the mobile lifting frame, the block 32 is pulled outward by the pull rod 33, and the spring 34 is compressed, so that the block 32 is retracted into the through hole 31, so that the block 32 is in contact with the connecting block 8 and fixed, and the equipment box 4 can be removed from the mobile frame. When installing the equipment box 4, the pull rod 33 is pulled outward to retract the block 32, and the connecting block 8 is aligned with the groove 30 on the fixing seat 3 and inserted. The pull rod 33 is released, and under the elastic force of the spring 34, the block 32 and the pull rod 33 are reset, so that the block 32 can extend into the groove 30 and be fixed above the horizontal part of the connecting block 8, thereby effectively fixing the connecting block 8 and the equipment box 4, making the placement of the equipment box 4 more convenient.

[0028] The rear side of the equipment box 4 is provided with a mounting fixture 43, which is used to fix the equipment box 4 to the mounting column of the detection area. In this embodiment, the mounting fixture 43 adopts a clamp structure, which can make it easier to install and remove the equipment box 4 on the mounting column.

[0029] A retractable opening is provided on the front side of the equipment box 4, and a support cover 41 is movably provided at the retractable opening, and a detection alarm 42 is fixedly installed at one end of the inner side of the support cover 41; a connecting rod assembly and a motor 5 are provided in the equipment box 4, and the motor 5 is power-connected to the connecting rod assembly. The connecting rod assembly is connected to the other end of the support cover 41 away from the detection alarm 42. The movement of the connecting rod assembly can drive the support cover 41 to snap into place at the retractable opening or extend the support cover 41 horizontally outward. Specifically, the connecting rod assembly includes a first connecting rod 61, a second connecting rod 62, a third connecting rod 63 and a fourth connecting rod 64. The first connecting rod 61 is arranged above the second connecting rod 62. One end of the first connecting rod 61 and the second connecting rod 62 are on the same vertical plane and are both rotatably connected to the inner wall of the equipment box 4 through corresponding rotating shafts; the other end of the first connecting rod 61 is rotatably connected to the lower end of the support cover 41, one end of the third connecting rod 63 is rotatably connected to the middle of the first connecting rod 61, and the fourth connecting rod 64 is arranged parallel to the first connecting rod 61. One end of the fourth connecting rod 64 is rotatably connected to the middle of the support cover 41, and the other end of the second connecting rod 62, the other end of the third connecting rod 63 and the other end of the fourth connecting rod 64 are rotatably connected together; the motor 5 is installed on the equipment box 4, and its output shaft is concentrically fixed to the rotating shaft of the rotation connection of the first connecting rod 61 on the equipment box 4.

[0030] like Figure 2 and 3 As shown, when the motor 5 drives the first connecting rod 61 to rotate counterclockwise via the rotating shaft, the second connecting rod 62 will swing clockwise. Since the fourth connecting rod 64 is arranged parallel to the first connecting rod 61, the third connecting rod 63 and the fourth connecting rod 64 can support and link the support cover 41, causing it to extend outward while also swinging clockwise until the support cover 41 rotates to a horizontal position, thereby allowing the detection alarm 42 to extend from the equipment box 4 and be placed in the detection area. When the detection is completed, the motor 5 can be used to drive the first connecting rod 61 to rotate in the opposite direction. The second connecting rod 62, the third connecting rod 63 and the fourth connecting rod 64 can then be used to rotate the support cover 41 counterclockwise to snap it into the retractable opening, allowing the detection alarm 42 on the support cover 41 to be retracted into the equipment box 4. This prevents the detection alarm 42 from being contaminated and corroded by corrosive gases, dust and other debris in the chemical workshop, thereby significantly improving the service life and detection accuracy of the detection alarm 42.

[0031] Due to the rotary connection relationship of the four connecting rods, the support cover plate 41 cannot be recovered to the vertical state, and the receiving and releasing opening on the front side of the equipment box 4 is upwardly inclined, so that the support cover plate 41 can be effectively matched with the receiving and releasing opening. Moreover, after detecting the state of the support cover plate 41 overturning the recovery detection alarm 42, the receiving and releasing opening is upwardly and rightwardly inclined, so that the top surface of the equipment box 4 can effectively shield the top to avoid that the liquid and other sundries falling from the gap between the support cover plate 41 and the receiving and releasing opening enter the inside of the equipment box 4. In addition, the four peripheral edges of the support cover plate 41 are provided with sealing rings matched with the receiving and releasing opening, so that the sealing performance between the support cover plate 41 and the equipment box 4 can be obviously improved.

[0032] The inside of the equipment box 4 is provided with the battery pack 7, so that stable power supply can be provided for the motor 5 and the detection alarm 42.

[0033] When the utility model is used, the equipment box 4 can be fixedly connected to the fixing seat 3 above the lifting rod 2 through the connecting block 8, the support cover plate 41 is opened by the motor 5 driving the connecting rod assembly, the detection alarm device is placed outside the equipment box 4, and then the height of the lifting rod 2 is lifted to cooperate with the movement of the walking base 1 to move in the detection area. When fixed-point detection is needed or narrow impassable areas and detection areas that the height of the lifting rod 2 cannot reach are encountered, the connecting block 8 can be separated from clamping by pulling the pull rod 33 to drive the clamping block 32 to move, so that the equipment box 4 can be quickly taken off from the fixing seat 3, the equipment box 4 is fixed in the detection area through the mounting fixing part 43, the detection alarm 42 is stretched out from the equipment box 4 by the motor 5 driving, and effective environmental protection safety detection can be realized.

[0034] Obviously, the above-described embodiments are only some embodiments of the present application, not all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing specific embodiments, or equivalently replace some technical features therein. Any equivalent structure made by using the contents of the specification and drawings, directly or indirectly applied to other related technical fields, is also within the patent protection scope of the present application.
