DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-8 The present invention provides the following technical solutions: a trash rack pressure monitoring device, comprising a fixing frame 1, a trash blocking mechanism 2 is slidably connected inside the fixing frame 1, a pressure sensor 9 is arranged inside the trash blocking mechanism 2, a control mechanism 3 is arranged above the fixing frame 1, an audible and visual alarm 5 is arranged above the control mechanism 3, a rainproof top 4 is fixedly connected above the control mechanism 3 and located on the periphery of the audible and visual alarm 5, an installation component 8 is arranged between the trash blocking mechanism 2 and the pressure sensor 9, a protection component 6 is arranged below the rainproof top 4 and located on the periphery of the audible and visual alarm 5, and a sound amplification component 7 is arranged inside the protection component 6.

[0030] Specifically, the protection assembly 6 includes a top protection frame 61 and a transparent protection frame 63. The top protection frame 61 is fixedly connected to the bottom of the rainproof top 4, and the transparent protection frame 63 is arranged inside the top protection frame 61.

[0031] By adopting the above technical solution, the sound and light alarm 5 is installed on the top of the control mechanism 3 and is located between the top protective frame 61 and the transparent protective frame 63. Under the action of the top protective frame 61 and the transparent protective frame 63, the sound and light alarm 5 can be shielded and protected to prevent debris in the external environment from directly colliding with the sound and light alarm 5, thereby preventing the sound and light alarm 5 from being damaged.

[0032] Specifically, the protection assembly 6 also includes a moving frame 62, a fixing member 64 and a moving block 65. The moving frame 62 is fixedly connected to both sides of the top protection frame 61 below the rainproof top 4. The moving block 65 is fixedly connected to the side wall of the transparent protection frame 63 and located inside the moving frame 62. The fixing member 64 is provided between the moving frame 62 and the moving block 65.

[0033] By adopting the above technical solution, after the sound and light alarm 5 is installed above the control mechanism 3, the transparent protective frame 63 is moved downward, and the transparent protective frame 63 moves downward to drive the moving block 65 to move inside the moving frame 62. When the transparent protective frame 63 moves to fit the top wall of the control mechanism 3, the fixing member 64 is used to fix the moving block 65 and the moving frame 62, and then the transparent protective frame 63 can be limited and fixed to ensure the stability of the placement of the transparent protective frame 63.

[0034] Specifically, the fixing member 64 includes an external box 641, a tightening screw 642, a return spring 643, a fixing rod 644 and a fixing groove 645. The moving frame 62 and the moving block 65 are both provided with a fixing groove 645. The external box 641 is fixedly connected to the side wall of the moving frame 62 and located at the periphery of the fixing groove 645. The fixing rod 644 is slidably connected to the inside of the external box 641. The return spring 643 is fixedly connected between the fixing rod 644 and the external box 641. The tightening screw 642 is threadedly connected to the side wall of the external box 641 and located at one side of the fixing rod 644.

[0035] By adopting the above technical solution, after the transparent protective frame 63 moves to fit the top wall of the control mechanism 3, the moving block 65 then fits the inner bottom wall of the moving frame 62, and then the tightening screw 642 is rotated to make it rotate and move along the external box 641. The tightening screw 642 rotates and moves to push the fixed rod 644 to move, and the movement of the fixed rod 644 drives the reset spring 643 to stretch. When the fixed rod 644 is fully inserted into the fixed groove 645, stop rotating the tightening screw 642, and use the fixed rod 644 to plug and fix the moving block 65 and the moving frame 62.

[0036] When this embodiment is in use, after installing the sound and light alarm 5 above the control mechanism 3, lower the transparent protective frame 63. The downward movement of the transparent protective frame 63 drives the moving block 65 to move inside the moving frame 62. When the transparent protective frame 63 moves and fits against the top wall of the control mechanism 3, rotate the tightening screw 642 so that it rotates and moves along the external box 641. The rotation and movement of the tightening screw 642 push the fixing rod 644 to move. The movement of the fixing rod 644 drives the tension of the return spring 643. When the fixing rod 644 is completely inserted into the fixing groove 645, stop rotating the tightening screw 642. Under the action of the top protective frame 61 and the transparent protective frame 63, the sound and light alarm 5 can be shielded and protected, preventing debris in the external environment from directly colliding with the sound and light alarm 5, thereby avoiding damage to the sound and light alarm 5. Then, install the sewage interception mechanism 2 inside the fixing frame 1 at the water inlet position. During subsequent use, water flows out through the pores on the sewage interception mechanism 2, while the dirt in the water is blocked by the sewage interception mechanism 2. The dirt exerts pressure on the sewage interception mechanism 2. At the same time, the pressure sensor 9 can be used to monitor the pressure value on the sewage interception mechanism 2. When the pressure value monitored by the pressure sensor 9 reaches the preset threshold, the pressure sensor 9 transmits a signal to the control mechanism 3. After receiving the signal, the control mechanism 3 immediately triggers the operation of the sound and light alarm 5. The sound and light alarm 5 operates and emits a sound and light alarm to remind the staff. At the same time, the control mechanism 3 synchronously sends the alarm signal to terminals such as the water conservancy workstation to remind the staff, facilitating the staff to clean the dirt on the sewage interception mechanism 2 in a timely manner;

[0037] Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is that the sound amplification component 7 includes an arc-shaped block 71, a support ring 72, a support net 73, a loudspeaker 74, and a limiting cylinder 75. A support ring 72 is arranged inside the top protective frame 61. An arc-shaped block 71 is fixedly connected to the side wall of the support ring 72. A support net 73 is fixedly connected to the inner side wall of the support ring 72. A loudspeaker 74 is arranged above the support net 73. A limiting cylinder 75 is fixedly connected to the side wall of the support ring 72 and located outside the loudspeaker 74.

[0039] When this embodiment is in use, place the loudspeaker 74 on the support net 73. The support ring 72 and the support net 73 can be used to support the loudspeaker 74, and the limiting cylinder 75 can be used to limit the loudspeaker 74 to prevent the loudspeaker 74 from detaching from the support ring 72. Subsequently, the sound and light alarm emitted by the operation of the sound and light alarm 5 is amplified by the loudspeaker 74 and then spreads to the surrounding environment, facilitating the surrounding staff to obtain the sound and light alarm sound in a timely manner, and further facilitating the staff to clean the dirt on the sewage interception mechanism 2 in a timely manner;

[0040] Embodiment 3

[0041] The present embodiment is different from the first embodiment and the second embodiment in that the installation assembly 8 includes a plug-in frame 81 and a top sealing plate 86. The plug-in frame 81 is slidably connected to the interior of the dirt-blocking mechanism 2, and one end of the plug-in frame 81 is fixedly connected to the top sealing plate 86.

[0042] Specifically, a limiting block is fixedly connected on the inner wall of the dirt-blocking mechanism 2 and below the top sealing plate 86, a limiting hole is provided on the limiting block, and a limiting rod is fixedly connected inside the dirt-blocking mechanism 2 and inside the limiting hole.

[0043] By adopting the above technical solution, during the movement of the plug-in frame 81, with the cooperation of the limiting holes and the limiting rods, a guiding effect can be provided for the movement of the plug-in frame 81, thereby improving the stability of the movement of the plug-in frame 81.

[0044] Specifically, the mounting assembly 8 includes a sealing ring 82, a threaded cylinder 83, a threaded rod 84 and a pressing cylinder 85. The threaded rod 84 is fixedly connected to one side of the top sealing plate 86 above the dirt blocking mechanism 2. The threaded cylinder 83 is threadedly connected to the outer wall of the threaded rod 84. One end of the threaded cylinder 83 is fixedly connected to the pressing cylinder 85. The end of the pressing cylinder 85 close to the dirt blocking mechanism 2 is fixedly connected to the sealing ring 82.

[0045] By adopting the above technical scheme, the plug-in frame 81 is moved and plugged into the interior of the dirt-blocking mechanism 2, and the top sealing plate 86 is moved accordingly to overlap the interior of the dirt-blocking mechanism 2, and then the threaded tube 83 is rotated and screwed onto the threaded rod 84, and the clamping tube 85 is rotated and moved toward the dirt-blocking mechanism 2. The rotation of the clamping tube 85 drives the sealing ring 82 to rotate and move. When the sealing ring 82 moves and fits to the top wall of the dirt-blocking mechanism 2, the rotation of the clamping tube 85 is stopped, and the top sealing plate 86 can be clamped and fixed by the clamping tube 85, and then the plug-in frame 81 can be limited and fixed, which is convenient for the disassembly and assembly of the plug-in frame 81, and then it is convenient for the disassembly and assembly of the pressure sensor 9, and it is convenient for the operator to perform maintenance and replacement operations on the pressure sensor 9.

[0046] When this embodiment is used, the pressure sensor 9 is installed on the side wall of the plug-in frame 81, and then the plug-in frame 81 is moved and plugged into the interior of the dirt-blocking mechanism 2, and the top sealing plate 86 is moved accordingly to overlap the interior of the dirt-blocking mechanism 2, and then the threaded tube 83 is rotated and screwed onto the threaded rod 84, and the clamping tube 85 is rotated and moved toward the dirt-blocking mechanism 2. The rotation of the clamping tube 85 drives the sealing ring 82 to rotate and move. When the sealing ring 82 moves and fits to the top wall of the dirt-blocking mechanism 2, the rotation of the clamping tube 85 is stopped. The clamping tube 85 can be used to clamp and fix the top sealing plate 86, and then the plug-in frame 81 can be limited and fixed, which is convenient for the disassembly and assembly of the plug-in frame 81, and then the disassembly and assembly of the pressure sensor 9 is convenient, and it is convenient for the operator to perform maintenance and replacement operations on the pressure sensor 9.

[0047] The structure and principle of the trash-blocking mechanism 2 composed of the side bracket, cavity, strip groove, vertical rod, cross rod, frame, vertical plate, pressure rod and connecting rod in the present invention have been disclosed in a trash rack pressure monitoring device disclosed in Chinese patent application No. 202420609714.1, and its working principle is: the inner sides of the fixed frame 1 are slidably connected with the side brackets, the two opposite end faces of the two side brackets are provided with strip grooves, the inner sides of the side brackets are provided with cavities, a plurality of cross rods are fixed between the two side brackets 170, a vertical rod is fixed between the plurality of cross rods, and a pressure sensor 9 is provided. It is installed inside the cavity, with a frame fixed between the two strip grooves, and a plurality of horizontally arranged connecting rods and a plurality of vertically arranged vertical plates are installed in the opening of the frame, and the connecting rods and the vertical plates are staggered. A plurality of pressure rods are fixed on both sides of the rear end face of the frame, and the pressure rods penetrate into the cavity and abut against the pressure sensor 9. When in use, water flows through the gap between the vertical plates and the connecting rods, and the dirt in the water flow is intercepted by the vertical plates and the connecting rods and accumulated on the front side of the vertical plates and the connecting rods. The dirt exerts pressure on the vertical plates and the connecting rods at the same time, and the pressure is transmitted to the frame and transmitted to the pressure sensor 9 through the frame and the pressure rods.

[0048] The structure and principle of the control mechanism 3 composed of a control cabinet, a controller, and a wireless signal transceiver in the present invention have been disclosed in a trash rack pressure monitoring device disclosed in Chinese patent application No. 202420609714.1, and its working principle is: a control cabinet is fixedly connected to the top of the fixed frame 1, a controller is installed on the rear side wall inside the opening of the control cabinet, and a wireless signal transceiver is provided below the controller. When in use, when the monitored pressure value reaches a preset threshold, the pressure sensor 9 transmits a signal to the controller. After receiving the signal, the controller immediately triggers the operation of the sound and light alarm 5, and the sound and light alarm 5 runs and emits a sound and light alarm to remind the staff; at the same time, the wireless signal transceiver synchronously sends the alarm signal to the water conservancy workstation and other terminals to remind the staff.

[0049] Working principle and usage process of the present invention: The pressure sensor 9 of the present invention is installed on the side wall of the plug-in frame 81, and then the plug-in frame 81 is moved and inserted into the inside of the trash interception mechanism 2. The top sealing plate 86 then moves and is placed on the inside of the trash interception mechanism 2. Then, the threaded cylinder 83 is rotated and screwed onto the threaded rod 84. The pressing cylinder 85 then rotates and moves towards the trash interception mechanism 2. The rotation and movement of the pressing cylinder 85 drive the rotation and movement of the sealing ring 82. When the sealing ring 82 moves and fits onto the top wall of the trash interception mechanism 2, stop rotating the pressing cylinder 85. The pressing cylinder 85 can be used to press and fix the top sealing plate 86, and thus limit and fix the plug-in frame 81, facilitating the disassembly and assembly operations of the plug-in frame 81, and further facilitating the disassembly and assembly operations of the pressure sensor 9, making it convenient for the operator to perform maintenance and replacement operations on the pressure sensor 9. After installing the sound and light alarm 5 above the control mechanism 3, at the same time, place the loudspeaker 74 on the support net 73. The support ring 72 and the support net 73 can be used to support the loudspeaker 74, and the limiting cylinder 75 can be used to limit the loudspeaker 74 to prevent the loudspeaker 74 from detaching from the support ring 72. Then, lower the transparent protective frame 63. The downward movement of the transparent protective frame 63 drives the moving block 65 to move inside the moving frame 62. When the transparent protective frame 63 moves and fits onto the top wall of the control mechanism 3, rotate the tightening screw 642 so that it rotates and moves along the external box 641. The rotation and movement of the tightening screw 642 push the fixing rod 644 to move. The movement of the fixing rod 644 drives the stretching of the return spring 643. When the fixing rod 644 is completely inserted into the fixing slot 645, stop rotating the tightening screw 642. Under the action of the top protective frame 61 and the transparent protective frame 63, the sound and light alarm 5 can be shielded and protected to prevent direct collision between sundries in the external environment and the sound and light alarm 5, and thus prevent damage to the sound and light alarm 5. Then, install the trash interception mechanism 2 inside the fixing frame 1 at the water inlet position. During subsequent use, water flows out through the pores on the trash interception mechanism 2, and the dirt in the water is blocked by the trash interception mechanism 2. The dirt exerts pressure on the trash interception mechanism 2. At the same time, the pressure sensor 9 can be used to monitor the pressure value on the trash interception mechanism 2. When the pressure value monitored by the pressure sensor 9 reaches the preset threshold, the pressure sensor 9 transmits a signal to the control mechanism 3. After receiving the signal, the control mechanism 3 immediately triggers the operation of the sound and light alarm 5. The sound and light alarm 5 operates and emits a sound and light alarm, which is amplified by the loudspeaker 74 and transmitted to the surrounding environment, facilitating the surrounding staff to timely obtain the sound and light alarm sound, and thus facilitating the staff to timely clean the dirt on the trash interception mechanism 2. At the same time, the control mechanism 3 synchronously sends an alarm signal to terminals such as the water conservancy work station to remind the staff, facilitating the staff to timely clean the dirt on the trash interception mechanism 2.
