Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a wireless voice alarm for detecting bad gas in bored pile operations. Background Art

[0002] Gas detection is a device that is commonly used in bored pile operations to continuously detect undesirable gases at the bottom of the hole and has a voice alarm function.

[0003] When bored piles are used for pile foundation construction, when the pile hole reaches a certain depth, gas detection equipment is needed to detect the bad gas at the bottom of the hole. After determining that the air environment at the bottom of the hole is safe, the detection equipment is taken away and the workers go down to work. The gas detection equipment on the market is usually wired. The hole mouth personnel lower the detector to the bottom of the hole with a signal transmission line to detect the gas content. After detecting that the bad gas exceeds the standard, it will emit monotonous sounds such as beeps. It cannot tell the operators which gas exceeds the standard according to different gas exceeding conditions. When the workers receive the alarm, if they do not check the display screen, they cannot understand which gas content exceeds the standard. Since the detectors are generally small in size, the screen for displaying data is generally small, and the information reading method is not friendly. Therefore, we propose a new type of wireless voice alarm for bad gas detection in bored pile operations. Utility Model Content

[0004] The utility model aims to solve the problem that the existing devices in the prior art will emit monotonous sounds such as buzzing sounds after detecting that the undesirable gas exceeds the standard, and cannot inform the operating personnel which gas exceeds the standard according to different gas exceeding the standard conditions.

[0006] Furthermore, a second voice module is internally connected to one side of the voice alarm body, and a loudspeaker is connected to the surface of the voice alarm body.

[0007] Furthermore, a display is connected to the surface of the detection alarm, and the MCU is electrically connected to an external power supply via a control switch.

[0008] Furthermore, the MCU is electrically connected to the gas sensor, the first voice module and the wireless transmission module.

[0009] Furthermore, a temperature control component is connected to the bottom of the voice alarm body, and the temperature control component includes a temperature control fan, and a frame is connected to the bottom of the temperature control fan.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1 - Figure 3 As shown, the utility model provides a wireless voice alarm for detecting bad gas in bored pile operation, including a voice alarm body 1 and a detection alarm 2, a gas sensor 3 is arranged inside one side of the detection alarm 2, a MCU4 is connected to one side of the gas sensor 3, a first voice module 5 is connected to one side of the MCU4, a wireless transmission module 6 is connected to the bottom of the first voice module 5, a second voice module 8 is connected inside one side of the voice alarm body 1, a loudspeaker 7 is connected to the surface of the voice alarm body 1, a display 9 is connected to the surface of the detection alarm 2, the MCU4 is electrically connected to an external power supply through a control switch, and the MCU4 is electrically connected to the gas sensor 3, the first voice module 5 and the wireless transmission module 6.

[0023] The effect achieved by the entire embodiment 1 is that, when in use, the detection alarm 2 is fixed to the hook of the bored pile hoisting operation, and rises and falls with the hook cycle during the operation to maintain continuous detection of the gas at the bottom of the bored pile hole. The voice alarm body 1 is then fixed near the winch at the hole mouth of the bored pile to continuously receive the underground gas content signal during the hole digging operation. Once the bad gas at the bottom of the hole exceeds the standard, the alarm information is obtained in time. When the detection alarm 2 is underground, the gas sensor 3 can detect the content of combustible gas, oxygen, carbon monoxide, and hydrogen sulfide, and the sensing output values ​​are different according to the different concentrations of each gas. These different values ​​are transmitted to the MCU4 for instruction The specified ID is sampled, analyzed and compared, the data is read out, and the concentration values ​​of each gas are displayed through the display 9. When there is an abnormal gas, its displayed value exceeds the preset value, and the MCU4 will output a signal, and the first voice module 5 will emit a voice alarm sound to prompt the bottom hole workers to evacuate immediately. When the MCU4 outputs a signal to control the detection alarm 2 to broadcast, it controls the wireless transmission module 6 to issue a command, and the command voice alarm body 1 receives the command, triggering the second voice module 8 to play the audio file, and then through the loudspeaker 7, the hole mouth workers are informed of the gas concentration at the bottom of the bored pile hole and the danger of adverse gases, so as to cooperate with the bottom hole workers to evacuate in time.

[0025] The effect achieved by the entire embodiment 1 is that the temperature-controlled fan 1001 can monitor the ambient temperature in real time through the built-in temperature sensor and intelligent control system, and automatically switch the working mode according to the set temperature value. When the ambient temperature of the voice alarm body 1 is higher than the set value, the fan will start the cooling mode and blow out cold air to lower the room temperature; when the ambient temperature is lower than the set value, the heating mode may be started to provide warm air to keep warm, thereby improving the stability of the voice alarm body 1 during use, and a filter 1005 is provided to isolate external dust, and when the filter 1005 needs to be cleaned, it can be directly pulled out of the installation slot 1004 and cleaned, and then the filter 1005 can be inserted into the installation slot 1004 and fixed by magnetic attraction through the magnetic attraction block 1003 and the magnet 1006, thereby increasing the service life of the voice alarm body 1.
