Description

Technical Field

[0001] The utility model relates to the technical field of gas detection equipment for construction, and more specifically, to a closed pool gas detection alarm device. Background Art

[0002] Sewage pools or biogas pools are relatively closed construction spaces, and harmful gas detection is required before construction work in the pool. For example, the Chinese patent with announcement number CN114878649A discloses a composite multi-gas detector for deep power foundation pit operations, which is provided with a detector body and a retractable lifting bracket. The retractable lifting bracket hangs the detector body by a hanging ear through a hanging rope, and the detector body changes its spatial position with the telescopic movement and lifting movement of the retractable lifting bracket. However, unlike the deep power foundation pit, the internal space of the sewage pool or biogas pool is very large, and lowering the gas detector from the reserved pool mouth position cannot detect gas at other internal space positions. Therefore, it is urgent to design a device that can extend from the pool mouth position into the internal space of the pool body for gas detection. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a closed pool gas detection alarm device, which is provided with a bracket, a horizontal swing arm, a support, a fixed seat and a sleeve to movably support the lower probe rod. The swing of the horizontal swing arm and the rotation of the sleeve enable the lower probe rod to swing up and down and left and right to adjust the front end gas detector to move in the closed pool space to perform gas detection in a larger range, thereby solving the technical problem that the prior art can only detect vertically in the well through a rope hook detector but cannot perform multi-directional and larger-range detection in the internal space.

[0004] In order to achieve these purposes of the utility model, the utility model provides a closed pool gas detection alarm device, comprising: a bracket arranged at the pool mouth of the closed pool, a horizontal swing arm arranged at the bracket, a support arranged at the front end of the horizontal swing arm, a fixed seat plugged with the support, a sleeve rotatably connected to the fixed seat, a lower probe rod slidably sleeved with the sleeve, and a gas detector arranged at the front end of the lower probe rod;

[0008] Preferably, in the closed pool gas detection alarm device, the support is vertically fixed to the front end of the horizontal arm, and the support has a plug-in portion and a limit portion.

[0009] Preferably, in the closed pool gas detection alarm device, the fixing seat has a plug-in mating portion that cooperates with the plug-in portion, and the fixing seat is inserted into the support from top to bottom and is blocked by a limiting portion located below.

[0010] Preferably, in the closed pool gas detection alarm device, a fixed shaft is provided on the fixed seat, a bearing is provided on the sleeve, and the bearing is sleeved and fixed to the fixed shaft so that the sleeve can rotate relative to the fixed seat.

[0015] The utility model at least has the following beneficial effects:

[0016] The utility model is provided with a bracket, a horizontal swing arm, a support, a fixed seat and a sleeve to movably support the lower exploration rod. The swing of the horizontal swing arm and the rotation of the sleeve enable the lower exploration rod to swing up and down and left and right to adjust the front-end gas detector to move in the closed pool space to perform gas detection in a larger range, thereby solving the technical problem that the prior art can only vertically descend the well for detection by hanging a rope and hooking the detector but cannot perform multi-directional and larger-range detection in the internal space.

[0026] The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

[0027] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0028] like Figures 1 to 6As shown, a closed pool gas detection alarm device comprises: a bracket 10 arranged at a closed pool opening 60, a horizontal swing arm 20 arranged on the bracket, a support 30 arranged at the front end of the horizontal swing arm, a fixing seat 40 plugged with the support, a sleeve 50 rotatably connected to the fixing seat, a lower probe rod 70 slidably sleeved with the sleeve, and a gas detector 76 arranged at the front end of the lower probe rod;

[0029] The lower probe rod 70 extends downward from the closed pool mouth 60 into the internal space 61 of the pool body. The horizontal swing arm 20 swings and the sleeve 50 rotates, so that the lower probe rod 70 adjusts the position of the front end gas detector 76, thereby performing gas detection on the internal space 61 of the pool body.

[0030] like Figure 1 As shown, the bracket 10 is arranged above the pool mouth 60, which plays a supporting role and facilitates the construction workers to operate the lower probe rod 70. The horizontal swing arm 20 is swingably arranged on the bracket 10 and can swing left and right, so that the lower probe rod can adjust its position left and right as needed. The support 30, the fixed seat 40 and the sleeve 50 act as a fulcrum, which can provide a movable fulcrum for the lower probe rod 70, facilitate the operation of the lower probe rod 70, and the plug-in cooperation between the support 30 and the fixed seat 40 improves the convenience of disassembly and assembly. The length of the lower probe rod 70 is selected according to the size of the internal space of the pool body, and metal pipes, metal rods, etc. are all acceptable. The front end of the lower probe rod 70, that is, the lower end, is fixed with a gas detector 76, and the rear end of the lower probe rod, that is, the upper end, is used for control. The gas detector 76 can be an all-in-one gas detector, which can realize the detection of gases such as oxygen, methane, hydrogen sulfide and carbon monoxide.

[0031] When in use, the sleeve 50 is connected to the fixing seat 40 to form a whole, and the sleeve 50 is inserted into the lower probe rod 70; after the support 30, the horizontal swing arm 20 and the bracket 10 are installed, the bracket 10 is placed at the pool mouth of the closed pool body, and then the lower probe rod is extended downward from the pool mouth into the closed pool body, and the fixing seat 40 is inserted downward into the support 30 and relatively fixed, such as Figure 4 The figure shows the assembled state. Figure 6 As shown, after the closed pool body is cast, a pool opening 60 is left to facilitate access to the internal space for demoulding, waterproofing, etc. Before construction, the construction worker manipulates the probe rod at the closed pool body opening 60 to allow the gas detector at the front end to detect gas in the closed pool body internal space 61. Figure 4 and 5 As shown, by controlling the lower probe rod to swing left and right and up and down, the detection range of the internal space of the closed pool body can be expanded.

[0032] Further, in another embodiment, Figure 1 and 2As shown, the bracket 10 includes: a seat plate 102 opposite to each other, a transverse plate 101 connected to the seat plate, and a suspension rod 103 connected to the transverse plate and extending downward; the length of the transverse plate 101 is greater than the width of the pool opening 60. This embodiment uses the seat plate and the transverse plate to increase the contact area with the foundation and improve stability. The suspension rod extends downward into the pool opening to provide an installation position for the horizontal swing arm 20.

[0033] Further, in another embodiment, Figure 1 and 2 As shown, the horizontal swing arm includes: a rotating drum 201 and a horizontal arm 202; the rotating drum 201 is rotatably sleeved with the suspension rod 103, and the horizontal arm 202 is horizontally welded on the rotating drum 201, so that the horizontal arm 202 can swing horizontally. Preferably, the rotating drum is obtained by cutting a steel pipe, and the suspension rod uses a steel pipe with a smaller diameter. After the rotating drum is sleeved into the suspension rod, a round plate is welded at the lower end of the suspension rod to prevent the rotating drum from detaching. The horizontal arm 202 uses a steel plate or an I-shaped steel.

[0034] Further, in another embodiment, Figure 1 and 2 As shown, the support 30 is vertically fixed at the front end of the horizontal arm 202, and the support 30 has a plug-in portion 301 and a stopper portion 302. In the figure, the support is an I-beam structure, the waist of the I-beam structure is the plug-in portion 301, and a bottom plate is welded to the bottom of the I-beam structure as the stopper portion 302. The support 30 is welded or bolted to the horizontal arm 202.

[0035] Further, in another embodiment, Figure 1 and 2 As shown, the fixing seat 40 has a plug-in fitting portion 402 that cooperates with the plug-in portion, and the fixing seat 40 is inserted into the support 30 from top to bottom and is stopped by the limit portion located below. In the example, the plug-in fitting portion 402 is obtained by opening a notch on one side of a square tube 401, and the square tube 401 is preferably provided as a pair, which is fixed to the back plate 404 by welding through a fixing plate 405. When the square tube 401 is inserted downward into the plug-in portion 301 of the I-beam structure of the support 30, the plug-in fitting portion 402 is pressed against by the limit portion 302 and clamps the I-beam structure, thereby maintaining fixation.

[0036] Further, in another embodiment, Figure 1 and 2As shown, the fixing seat 40 is provided with a fixing shaft 406, and the sleeve 50 is provided with a bearing 502, which is sleeved and fixed with the fixing shaft 406, so that the sleeve 50 can rotate relative to the fixing seat. In the example, the fixing shaft 406 is welded and fixed on the back plate 404 of the fixing seat, the sleeve is a square sleeve 501, and has a sleeve hole 503 in the center, the outer ring of the bearing 502 is welded and fixed with the sleeve 50, and the inner ring of the bearing 502 is sleeved with the fixing shaft 406 by interference sleeve fit or sleeved and then welded to be fixed to each other, so that the sleeve 50 and the fixing seat 40 form a whole.

[0037] Further, in another embodiment, Figure 3 As shown, the lower probe rod 70 includes a main arm 71 and a secondary arm 72. The main arm 71 and the secondary arm 72 are fixed at an angle of 20 to 80 degrees. The main arm 71 is slidably connected with the sleeve 50. The gas detector 76 is arranged at the front end of the secondary arm 72. The upper end of the main arm 71 is used for holding and operating to change the position of the gas detector in the internal space of the closed pool body. In the legend, a latch 77 is also arranged on the upper part of the main arm 71. After the lower probe rod 70 is connected with the sleeve 50, the latch 77 is inserted to play a limiting role, preventing the lower probe rod 70 from being separated from the sleeve 50, and preventing the lower probe rod 70 from falling off the closed pool body during the construction operation.

[0038] Further, in another embodiment, Figure 3 As shown, the front end of the lower probe rod 70 is also provided with a nozzle 75, which is connected to a blower 74 through a pipeline 73, and is used to blow air into the internal space of the closed pool body. In the legend, the nozzle 75 and the gas detector 76 are installed at the front end of the lower probe rod 70. When the gas detector 76 detects that the harmful gas exceeds the standard, the blower can be started to introduce air to eliminate hidden dangers and prepare for subsequent construction.

[0039] Preferably, Figure 3 As shown, the lower probe rod 70 is a hollow structure, the pipeline 73 is connected with the hollow structure, and the hollow structure is connected with the nozzle 75. In the example, the pipeline 73 is connected with the top of the lower probe rod, and the gas of the blower is delivered to the nozzle 75 through the pipeline 73 and the lower probe rod 70.

[0040] Further, in another embodiment, Figure 7As shown, in order to transmit the gas data detected by the gas detector remotely and give an alarm in time, the present embodiment is provided with a controller, a wireless communication module, an alarm and a terminal device connected to the gas detector. The controller sends the gas detector detection data to the terminal device in real time through the wireless communication module. When the gas detector detects that oxygen, carbon monoxide, methane or hydrogen sulfide exceeds the threshold, the controller sends a signal to the alarm through the wireless communication module to start the alarm. The alarm can be a sound alarm or a vibration alarm. The wireless communication module can be a common module such as a WiFi module or a Bluetooth module. The terminal device can be a computer or a mobile phone. As an alternative, an existing gas detector with wireless communication function and alarm function can also be used instead of the present embodiment.

[0041] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
