Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically a combustible gas leak detection and early warning device. Background Technology

[0002] Combustible gas leak detection is a technology used to monitor the concentration of combustible gases in the environment. Typically, this detection requires the use of specialized sensors to detect the concentration of combustible gases in the environment. Once the sensor detects that the concentration of combustible gases exceeds a certain threshold, it will emit an audible or visual signal to alert people. There are many types of combustible gas leak detection instruments, mainly divided into portable gas detectors and fixed gas detectors. Portable gas detectors are suitable for scenarios that require mobile detection, such as inspections, emergency rescues, and confined space operations. Fixed gas detectors are often used for long-term monitoring in fixed locations such as factory workshops, warehouses, and gas supply stations. However, portable gas detectors on the market often do not have handles or other structures. When performing detection at higher locations, it is often necessary to add an external support rod and use adhesive tape or other structures to tie the portable gas detector to the end of the support rod. This installation method is inconvenient and can easily leave adhesive tape residue on the surface of the portable gas detector. Utility Model Content

[0003] The purpose of this invention is to provide a combustible gas leak detection and early warning device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combustible gas leak detection and early warning device, including a detection and early warning instrument body, a fixed base is fixedly installed on the back of the detection and early warning instrument body, a rotating head is rotatably connected to the fixed base through a pin shaft, and a four-stage telescopic rod is fixedly installed at the bottom of the rotating head;

[0005] The four-stage telescopic rod includes a hollow rod one, the top of which is fixedly connected to a rotating head. A hollow rod two is slidably sleeved on the outside of the hollow rod one, a hollow rod three is slidably sleeved on the outside of the hollow rod two, and a hollow rod four is slidably sleeved on the outside of the hollow rod three. The hollow rod one, hollow rod two, hollow rod three, and hollow rod four are internally connected.

[0006] A U-shaped bracket is fixedly installed on the back of the detection and early warning instrument body. An elastic silicone pad is fixedly installed inside the U-shaped bracket. The hollow rod is inserted into the elastic silicone pad. An integrally formed sealing ball head is provided inside the elastic silicone pad. The sealing ball head is inserted into the air hole on the hollow rod.

[0007] Furthermore, sealing rings are provided at the parts of hollow rod 2 that are slidably connected to hollow rod 1, hollow rod 3 that are slidably connected to hollow rod 2, and hollow rod 4 that are slidably connected to hollow rod 3.

[0008] Furthermore, a battery compartment is provided on the back of the detection and early warning device, and a battery compartment cover is snapped into the battery compartment.

[0009] Furthermore, a handle is fixedly installed at the bottom of the four-stage telescopic rod, and anti-slip textures are provided on the outer wall of the handle and the outer wall of the hollow rod. An auxiliary fixing component is fixedly installed at the bottom of the handle.

[0010] Furthermore, the auxiliary fixing component includes a mounting base, with rotating seats rotatably connected to the front and rear of the mounting base via pins, a connecting rod fixedly mounted at the bottom of the mounting base, and a pin fixedly mounted at the bottom end of the connecting rod.

[0011] Furthermore, a limit stop is fixedly installed on the outer wall of the rotating seat. The rotation radius of the limit stop is greater than the rotation radius of the rotating seat, and the limit stop is perpendicular to the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The device uses a four-stage telescopic rod as the grip section. When detecting in high or hard-to-reach areas, the four-stage telescopic rod can be extended, and then the detection and warning device body can be extended to the detection area for detection. The four-stage telescopic extension length is large, and the overall size is not too large when not in use, so it will not have a significant impact on carrying.

[0014] 2. The hollow rod one is secured with an elastic silicone pad to prevent the detector body from rotating relative to the four-stage telescopic rod during use. Because the hollow rods one, two, three, and four are internally connected, the four-stage telescopic rod cannot be pulled to extend or retract under the pressure difference after the sealing ball head blocks the air hole on the hollow rod one. The four-stage telescopic rod can only be pulled to extend or retract when the sealing ball head does not block the air hole, thus achieving stepless adjustment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a combustible gas leak detection and early warning device, including a detection and early warning instrument body 1, a fixed base 3 fixedly installed on the back of the detection and early warning instrument body 1, a rotating head 4 rotatably connected to the fixed base 3 via a pin shaft, and a four-stage telescopic rod 7 fixedly installed at the bottom of the rotating head 4. The four-stage telescopic rod 7 is used as a grip section. When detecting in high or difficult-to-reach places, the four-stage telescopic rod 7 can be extended, and then the detection and early warning instrument body 1 can be extended to the detection area for detection. Moreover, the four-stage telescopic extension length is large, and the overall volume is not too large when not in use, so it will not have a significant impact on carrying.

[0023] The four-stage telescopic rod 7 includes a hollow rod 1 701, the top of which is fixedly connected to the rotating head 4. A hollow rod 2 702 is slidably sleeved on the outside of the hollow rod 1 701. A hollow rod 3 703 is slidably sleeved on the outside of the hollow rod 2 702. A hollow rod 4 704 is slidably sleeved on the outside of the hollow rod 3 703. The hollow rods 1 701, 2 702, 3 703, and 4 704 are internally connected.

[0024] A U-shaped bracket 5 is fixedly installed on the back of the detection and early warning instrument body 1. An elastic silicone pad 6 is fixedly installed inside the U-shaped bracket 5. Hollow rod 701 is inserted into the elastic silicone pad 6. An integrally formed sealing ball head 10 is set inside the elastic silicone pad 6. The sealing ball head 10 is inserted into the air hole on the hollow rod 701. The elastic silicone pad 6 is installed and limited by the U-shaped bracket 5. The hollow rod 701 is locked by the elastic silicone pad 6. During use, the detection and early warning instrument body 1 is prevented from rotating relative to the four-stage telescopic rod 7. Because the hollow rods 701, 702, 703, and 704 are internally connected, after the sealing ball head 10 blocks the air hole on the hollow rod 701, the four-stage telescopic rod 7 cannot be pulled to extend or retract under the action of pressure difference. The four-stage telescopic rod 7 can only be pulled to extend or retract when the sealing ball head 10 does not block the air hole, which can achieve stepless adjustment.

[0025] Sealing rings 11 are provided at the parts where hollow rod 2 702 slides to hollow rod 1 701, hollow rod 3 703 slides to hollow rod 2 702, and hollow rod 4 704 slides to hollow rod 3 703. These measures increase the sealing performance of the connection and prevent air leakage. Since the main body 1 of the detection and early warning instrument has a small weight, the pressure acting on the connection is small. Therefore, only the sealing rings 11 are needed to achieve good sealing performance.

[0026] The back of the detection and warning device body 1 is provided with a battery compartment, and a battery compartment cover 2 is snapped into the battery compartment. The battery compartment cover 2 is provided to cover the battery compartment. Since the four-stage telescopic rod 7 can rotate relative to the detection and warning device body 1, when replacing the battery, the four-stage telescopic rod 7 can be rotated to separate the four-stage telescopic rod 7 from the battery compartment cover 2.

[0027] A handle 8 is fixedly installed at the bottom of the four-stage telescopic rod 7. The outer wall of the handle 8 and the outer wall of the hollow rod 704 are provided with anti-slip texture. The handle 8 and the anti-slip texture on the four-stage telescopic rod 7 and the handle 8 make it more convenient for users to hold and prevent their hands from slipping. An auxiliary fixing component 9 is fixedly installed at the bottom of the handle 8. The auxiliary fixing component 9 is used to fix the detection and early warning device on the ground.

[0028] The auxiliary fixing component 9 includes a mounting base 901. The front and rear of the mounting base 901 are rotatably connected to rotating seats 902 via pins. A connecting rod 903 is fixedly installed at the bottom of the mounting base 901. A pin 904 is fixedly installed at the bottom end of the connecting rod 903. By rotating the two rotating seats 902, the two connecting rods 903 are made to form a triangular shape. Then, the pin 904 at the bottom of the rod is inserted into the ground, thereby fixing the entire combustible gas leak detection and early warning device.

[0029] A limit stop 12 is fixedly installed on the outer wall of the rotating seat 902. The rotation radius of the limit stop 12 is greater than the rotation radius of the rotating seat 902. The limit stop 12 is perpendicular to the connecting rod 903. The limit stop 12 is set to limit the maximum rotatable angle of the rotating seat 902.

[0030] Working principle: When using this device, if it is necessary to detect objects at high places or inaccessible locations, first rotate the four-stage telescopic rod 7 to disengage the hollow rod 701 from the elastic silicone pad 6. At this time, the air vents on the hollow rod 701 are exposed. Then, pull the four-stage telescopic rod 7 to extend it. After extending to a certain length, rotate the four-stage telescopic rod 7 to rotate the hollow rod 701 back into the elastic silicone pad 6. At this time, the sealing ball head 10 blocks the air vents on the hollow rod 701, thus locking the length of the four-stage telescopic rod 7. After activating the detection and warning device body 1, you can hold the handle 8 and extend the detection and warning device body 1 into the detection area. The detection and warning device body 1 will detect the leaked gas and issue an alarm after detecting a gas leak.

[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
