Description

Technical Field

[0001] This application relates to the field of fire hydrant flow detection technology, and in particular to a remote fire hydrant flow detection device. Background Technology

[0002] Fire hydrants are fixed water supply facilities connected to water supply pipelines, providing a powerful guarantee for quickly extinguishing large fires. In fire extinguishing systems, there are many types of fire hydrants, broadly divided into indoor and outdoor fire hydrants. Besides their primary function of extinguishing fires for fire trucks or other mobile firefighting equipment, outdoor fire hydrants can also provide water for municipal construction and maintenance under necessary conditions. For example, water for municipal road construction and irrigation of municipal green spaces. For municipal water supply networks, unnecessary water waste should be avoided. Water waste from fire hydrants is mainly due to improper use of fire hydrants or aging of some hydrant sealing elements, resulting in unnecessary waste of water resources.

[0003] To facilitate real-time monitoring and control of water flow in fire hydrants, intelligent flow detectors with remote transmission capabilities have emerged on the market. This type of intelligent wireless flow detector for fire hydrants mainly consists of a housing, a pipe clamp installed on the back of the housing, the main body of the intelligent wireless flow detector installed inside the housing, a sampling tube installed at the bottom of the housing, and a cover installed at the opening of the housing. In use, the sampling tube is connected to the inside of the fire hydrant, thereby using the main body of the intelligent wireless flow detector to monitor and transmit the water flow in the fire hydrant in real time.

[0004] While existing intelligent wireless flow detectors can detect the water flow in fire hydrants and transmit the results to a remote control terminal, they suffer from several drawbacks. First, installing the housing on the fire hydrant pipe wall with pipe clamps requires external tools to tighten bolts for secure fixing, making the process cumbersome and inefficient. Second, installing the cover also requires gradually tightening bolts to achieve the limited installation, further complicating the process. These issues hinder efficient installation and use of the detection device, as well as convenient maintenance and repair of the intelligent flow detector. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a fire hydrant flow remote detection device that enables efficient installation and fixation of the detection box and cover without the aid of external selection tools, facilitating the efficient use of the device.

A sampling tube is installed in the center of the bottom of the detection housing, and a connector is connected to the bottom end of the sampling tube. An installation assembly is installed on the back of the detection housing. The installation assembly includes a groove, a clamping block, a first mounting plate, a bidirectional lead screw, and a handwheel. The first mounting plate is directly welded to the detection housing. The groove is formed in the center of the side wall of the first mounting plate opposite to the detection housing.

The limiting groove is opened in the middle of the side wall of the cover. The limiting post is directly opposite the limiting groove. The pull cover is connected to the end of the limiting post that is away from the limiting groove. The limiting post passes through the second mounting plate. The first spring is installed between the pull cover and the second mounting plate.

[0008] Optionally, guide push assemblies are also installed at the four corners of the opening side of the detection box and between the box cover. The guide push assemblies include a spring, a sliding hole, and a guide post.

[0009] Optionally, there are four sliding holes, four springs, and four guide posts, and the four guide posts are respectively connected to the four corners of the back of the box cover. The sliding holes are opened at the four corners of the opening side of the detection box, and the springs are located inside the sliding holes.

[0010] Optionally, the guide post is slidably engaged with the sliding hole, one end of the second spring is welded to the sliding hole, and the end of the second spring facing the guide post is a free end.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of the existing intelligent wireless flow detector for fire hydrants will be introduced first.

[0026] The existing intelligent wireless flow detector for fire hydrants mainly consists of a housing, a pipe clamp installed on the back of the housing, the main body of the intelligent wireless flow detector installed inside the housing, a sampling tube installed at the bottom of the housing, and a cover installed at the opening of the housing. In use, the sampling tube is connected to the inside of the fire hydrant, so as to use the main body of the intelligent wireless flow detector to detect and transmit the water flow in the fire hydrant in real time.

[0027] Please see Figures 1-4 This application discloses a remote fire hydrant flow detection device, comprising a detection box 1, an intelligent wireless flow detector 5 installed in the center of the detection box 1, a sampling tube 3 installed in the center of the bottom of the detection box 1, a connector 4 connected to the bottom of the sampling tube 3, and an installation assembly 6 installed on the back of the detection box 1. The installation assembly 6 includes a groove 61, a clamping block 62, a mounting plate 63, a bidirectional lead screw 64, and a handwheel 65. The mounting plate 63 is directly welded to the detection box 1. The groove 61 is formed in the center of the side wall of the mounting plate 63 facing away from the detection box 1. The bidirectional lead screw 64 is installed in the groove 61, and the handwheel 65 is located outside the bidirectional lead screw 64. The exposed end has two clamping blocks 62, and the two clamping blocks 62 are respectively connected to the threaded parts with opposite directions of rotation at both ends of the bidirectional lead screw 64. A cover 2 is installed on the open side of the detection box 1. Two limiting components 7 are symmetrically installed between the cover 2 and the two long side walls of the outer side of the detection box 1. The limiting components 7 include a limiting post 71, a pull cover 72, a second mounting plate 73, a limiting groove 74, and a first spring 75. The limiting groove 74 is opened in the middle of the side wall of the cover 2. The limiting post 71 is directly opposite the limiting groove 74. The end of the limiting post 71 facing away from the limiting groove 74 is connected to the pull cover 72. The limiting post 71 passes through the second mounting plate 73. The first spring 75 is installed between the pull cover 72 and the second mounting plate 73.

[0028] Specifically, when installing the detection box 1 onto the outside of the fire hydrant pipe wall, the clamping blocks 62 are first placed between the fire hydrant pipe walls. Then, the double-acting screw 64 is rotated by the handwheel 65. After the double-acting screw 64 rotates, the two clamping blocks 62 will move closer to each other under the guidance of the threaded drive and the groove 61. This allows for quick clamping of the fire hydrant pipe wall during the process of the clamping blocks 62 moving closer together, thus achieving quick clamping and installation of the detection box 1 on the fire hydrant. This eliminates the tedious operation of using external screw-tightening tools to tighten bolts for fixing. When installing the cover 2, the pull cover 72 and the limiting post 71 are first pulled outward relative to the mounting plate 73. Then, the cover 2 is attached to the open side of the detection box 1. Then, simply loosening the pull cover 72 allows the limiting post 71 to be inserted into the limiting groove 74 in the cover 2 under the reset action of the spring 75. This achieves quick installation and limiting of the cover 2, eliminating the tedious operation of repeatedly tightening bolts for fixing, and facilitating efficient assembly and use of the device.

[0029] Please see Figure 2 , Figure 3 and Figure 5 The four corners of the opening side of the detection box 1 and the box cover 2 are respectively equipped with guide push assembly 8, which includes spring 81, sliding hole 82 and guide post 83.

[0030] In one implementation, when installing the cover 2, inserting the guide post 83 into the sliding hole 82 can ensure that the cover 2 is stably fitted on the opening side of the detection box 1 with the cooperation of the guide post 83 and the sliding hole 82. When the cover 2 contacts the opening side of the detection box 1, the spring 81 is compressed, and the limiting groove 74 on the cover 2 is exactly aligned with the limiting post 71, so that the cover 2 can be quickly limited and fixed on the opening side of the detection box 1 after the limiting post 71 is inserted into the limiting hole.

[0031] Please see Figure 2 , Figure 3 and Figure 5 There are four sliding holes 82, four springs 81, and four guide posts 83. The four guide posts 83 are connected to the four corners of the back of the box cover 2 respectively. The sliding holes 82 are opened at the four corners of the opening side of the detection box 1, and the springs 81 are located inside the sliding holes 82.

[0032] As one implementation method, the four guide posts 83 and the four sliding holes 82 work together to make the lid 2 close more smoothly towards the opening side of the detection box 1, thus avoiding any tilting.

[0033] Please see Figure 2 and Figure 3 The guide post 83 is slidably fitted with the sliding hole 82, one end of the spring 81 is welded to the sliding hole 82, and the end of the spring 81 facing the guide post 83 is a free end.

[0034] In one implementation, after the lid 2 is installed at the upper limit of the detection box body 1, the second spring 81 is in the compression turntable, and the free end of the second spring 81 is in contact with the guide post 83. When the fragrance of the limiting post 71 is released, the guide post 83 will be pushed out of the sliding hole 82 under the action of the second spring 81, so as to realize the convenient separation of the lid 2 and the detection box body 1.

[0035] Please see Figure 2 The bidirectional lead screw 64 is rotatably connected to the groove 61, the bidirectional lead screw 64 is welded to the handwheel 65, and the bidirectional lead screw 64 is threadedly connected to the clamping block 62.

[0036] As one implementation method, welding the bidirectional lead screw 64 to the handwheel 65 ensures that the bidirectional lead screw 64 rotates synchronously with the handwheel 65 for adjustment, while the threaded connection allows the slider to slide and adjust conveniently along the groove 61.

[0037] Please see Figure 1 and Figure 2 The clamping wall of the clamping block 62 has an arc-shaped concave structure, and the two clamping blocks 62 slide in conjunction with the groove 61.

[0038] As one implementation method, the clamping wall of the clamping block 62 is designed as an arc-shaped structure, which can ensure that the clamping block 62 has a larger contact area with the fire hydrant pipe wall, thereby achieving stable clamping and installation of the device on the outer wall of the fire hydrant.

[0039] Please see Figures 1-3 Mounting plate 2 73 has an L-shaped structure. Mounting plate 2 73 is welded to the outer wall of the detection box 1. Limiting post 71 penetrates mounting plate 2 73 and slides with mounting plate 2 73.

[0040] As one implementation method, the second mounting plate 73 is mainly used to provide an installation base for the pull cover 72 and the limiting post 71. The sliding fit installation method makes the sliding adjustment of the limiting post 71 relative to the second mounting plate 73 more convenient.

[0041] Please see Figures 1-4 The limiting post 71 passes through the spring 75. One end of the spring 75 is welded to the pull cover 72, and the other end of the spring 75 is welded to the mounting plate 73.

[0042] In one implementation, the spring 75 is mainly used to realize the automatic reset of the cover 72 after it is pulled outward, to ensure the convenient insertion of the limiting post 71 into the limiting groove 74 on the cover 2, and to realize the quick limiting of the cover 2.

[0043] Please see Figures 1-3 The limiting post 71 slides with the groove 61, and there are no fewer than three limiting posts 71 on each pull cover 72.

[0044] As one implementation method, the sliding fit installation method makes the installation of the limiting post 71 and the groove 61 more convenient, and ensures that there are no less than three limiting posts 71, which can ensure that the box cover 2 is stably limited after the limiting post 71 and the limiting groove 74 are engaged.

[0045] The specific working principle is as follows: First, the clamping blocks 62 are placed between the fire hydrant pipe walls. Then, the handwheel 65 is used to rotate the double-acting screw 64. After the double-acting screw 64 rotates, the two clamping blocks 62 move closer together under the guidance of the threaded drive and the groove 61. This allows for rapid clamping of the fire hydrant pipe wall during the process of the clamping blocks 62 moving closer together, achieving rapid clamping and installation of the detection box 1 on the fire hydrant. This eliminates the cumbersome operation of tightening bolts with external screwdrivers. After the device is installed on the fire hydrant, when installing the cover 2, first pull the cover 72 and the limiting post 71 outward relative to the mounting plate 73, then... Then, attach the cover 2 to the open side of the detection box 1. Then, simply loosen the pull cover 72, and under the reset action of the spring 75, the limiting post 71 will be inserted into the limiting groove 74 in the cover 2, thereby realizing the quick installation and limiting of the cover 2, eliminating the tedious operation of repeatedly tightening the bolts, and facilitating the efficient assembly and use of the device. After the cover 2 is installed, simply connect the connector 4 to the pre-reserved connector on the fire hydrant, and the water flow in the fire hydrant can be detected by the intelligent wireless flow detector 5, and the detection results can be transmitted to the remote control terminal, so that the remote control terminal staff can monitor the water flow in the fire hydrant in real time.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
