DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] In sewage treatment or water environment surveys, various detection equipment is often used to monitor water data. For example, in sewage treatment systems, it is necessary to test the pH value and dissolved oxygen of sewage water. These detection instruments all have detection heads. When used, the detection heads need to be placed in the water body to allow the water body to fully contact the detection heads to obtain accurate data. Whether the data obtained by the detection head is accurate depends on whether the detection head is in full contact with the water body. If the detection head is covered or blocked by pollutants in the water body, the accuracy of the data obtained by the detection head will be greatly reduced, or even the detection head will not be able to obtain data. However, in sewage treatment systems, the water body contains solid suspended matter such as activated sludge. As the detection head is used for a longer time, suspended matter such as activated sludge adheres to the detection head, hindering the contact between the detection head and the water body, affecting the accuracy of the data obtained by the detection head.

[0030] Generally, the detection equipment is permanently installed, so the detection head is often fixed in the water. If the detection head is clogged by suspended matter, it is necessary to stop the sewage treatment first and then clean the detection head, which will bring a lot of inconvenience.

[0031] Reference Figure 1 As shown, an underwater environment detection head air washing device of an embodiment of the utility model includes a protective cover 100 and a jet assembly 200. A receiving cavity is provided in the protective cover 100, and a flow passage 110 is provided on the side wall of the protective cover 100. The flow passage 110 connects the receiving cavity with the outside of the protective cover 100. The protective cover 100 is used to cover the detection head and place the detection head in the receiving cavity; the jet assembly 200 is arranged on the protective cover 100, and the air outlet of the jet assembly 200 faces the receiving cavity. The underwater environment detection head air washing device of the utility model embodiment can quickly and effectively wash the detection head, while reducing the possibility of pollutants covering the detection head.

[0032] The shield 100 is used to be connected to the detection head, and the detection head is placed in the accommodating chamber inside the shield 100. Since the shield 100 is provided with a flow passage 110, the water flow can enter the accommodating chamber through the flow passage 110 and contact the detection head, so the shield 100 will not affect the contact between the water body and the detection head. Furthermore, the size of the flow passage 110 can be adjusted during the design, and a suitable flow passage 110 can also prevent suspended matter in the water body from entering the accommodating chamber, reducing the possibility of pollutants covering the detection head. In some embodiments, the flow passage 110 can be a grille slot, which is mainly used to block oversized pollutants.

[0033] The jet assembly 200 is arranged on the shield 100, and its gas outlet faces the accommodating cavity in the shield 100. That is, after the detection head is installed in the accommodating cavity, the jet assembly 200 can spray gas of appropriate pressure to the detection head, so as to quickly and effectively flush the detection head.

[0034] It can be understood that the jet assembly 200 includes a base 210, a nozzle 220 and a connector 230. The base 210 is connected to the shield 100. The base 210 is provided with an air chamber. The nozzle 220 is detachably mounted on the base 210, and the nozzle 220 is communicated with the air chamber. The nozzle 220 faces the accommodating cavity. The connector 230 is arranged on the base 210, and the connector 230 is communicated with the air chamber. The connector 230 is used to connect the air supply device.

[0035] The detachable connection between the base 210 and the shield 100 is convenient for the production of the underwater environment detection head air washing device, and for its installation and connection. After use, it is convenient to disassemble the base 210 to maintain the nozzle 220. The connector 230 is used to connect the air pipe, which is connected to the external air supply device. Preferably, compressed air can be provided by a fan, and an air tank is provided, and an air pipe is connected between the air tank and the connector 230. It should be understood that the air pipe can be a pressure-resistant and corrosion-resistant hose or hard pipe.

[0036] In some embodiments, a pressure reducing valve may be further provided between the gas storage tank and the connector 230. The pressure reducing valve is used to adjust the outlet pressure of the gas storage tank so that the air pipe pressure meets the pressure requirement of the nozzle 220. Preferably, the pressure reducing valve is provided at one end close to the gas storage tank, or at the outlet of the gas storage tank.

[0037] In some embodiments, a solenoid valve may be further provided between the gas storage tank and the connector 230, and the time for gas flushing the detection head may be controlled by controlling the on and off of the solenoid valve.

[0038] Reference Figure 2 As shown, it can be understood that the nozzle 220 is provided with a jet channel 221, one end of the jet channel 221 is connected to the air chamber, the end of the jet channel 221 close to the air chamber is the air inlet end, and the other end is the air outlet end. Along the direction from the air inlet end to the air outlet end, the inner diameter of the jet channel 221 first shrinks and then expands, and the inner diameter of the jet channel 221 at the end face of the air inlet end is larger than the inner diameter at the end face of the air outlet end.

[0039] It should be understood that the nozzle 220 needs to eject gas, and a jet channel 221 must be provided. This embodiment further improves the structure of the jet channel 221. The inner diameter of the jet channel 221 is first reduced and then expanded. When the gas passes through the front end of the jet channel 221, due to the reduction of the inner diameter of the jet channel 221, according to the Bernoulli principle, the flow rate of the gas will increase. At the rear end of the jet channel 221, the inner diameter continues to expand, and the flow rate of the gas will decrease. After the gas is accelerated once at the front end of the jet channel 221, it will be appropriately decelerated at the rear end. In addition, the inner diameter of the end face of the outlet end of the jet channel 221 is smaller than the inner diameter of the end face of the inlet end, so the speed of the gas when it is finally ejected is greater than the speed when it is inlet. The faster flow rate of the gas has a better cleaning effect on the detection head. The gas is appropriately decelerated at the rear end of the jet channel 221 to prevent the gas from damaging the detection head.

[0040] It can be understood that the nozzle 220 is provided with a plurality of jet channels 221 , and the plurality of jet channels 221 are parallel and spaced apart.

[0041] The multiple jet channels 221 can disperse the gas so that the gas covers a wider area of ​​the detection head and improves the cleaning effect.

[0042] Reference Figure 3 As shown, it can be understood that the shield 100 is cylindrical, and a plurality of strip grooves 111 are opened on the side wall of the shield 100. The strip grooves 111 are parallel to the axis of the shield 100, and the plurality of strip grooves 111 are distributed along the circumference of the shield 100, and the plurality of strip grooves 111 form a flow channel 110.

[0043] The width of the strip groove 111 can be adjusted during design, and a suitable width can be selected for different water environments. A wider strip groove 111 can allow water to enter the receiving chamber more smoothly, but it is also easier to entrain large-diameter suspended matter.

[0044] Generally, the activated sludge in the sewage treatment system appears in a mass, so the strip groove 111 can well prevent the activated sludge from entering the receiving chamber and blocking the detection head. However, there may be small-diameter activated sludge or other suspended matter entering the receiving chamber. If the suspended matter covers the detection head, the jet assembly 200 needs to be used to flush the detection head.

[0045] It can be understood that the base 210 is detachably connected to the shield 100. In some embodiments, the base 210 is inserted into one end of the shield 100, and a first connecting bolt is provided between the base 210 and the shield 100. The first connecting bolt passes through the side wall of the shield 100 and is screwed into the base 210. In the above structure, the side wall of the shield 100 is correspondingly provided with a through hole for the first connecting bolt to pass through, and the base 210 is correspondingly provided with a threaded hole for the first connecting bolt to be screwed into.

[0046] Reference Figure 4 As shown, it can be understood that the nozzle 220 is provided with an outer edge portion 222 along the circumferential direction, the base 210 is provided with a groove 211, the nozzle 220 is installed on the base 210 and the outer edge portion 222 is placed in the groove 211, a second connecting bolt is provided between the outer edge portion 222 and the groove 211 and the surface of the outer edge portion 222 is tightly attached to the bottom surface of the groove 211.

[0047] In the above structure, the nozzle 220 and the base 210 can also be detachably connected. In different water environments or for different detection heads, the jet pressure can be adjusted by replacing the nozzle 220, or the size of the jet coverage can be adjusted. The jet pressure or the jet coverage can be differentiated by adjusting the internal structure of the nozzle 220. In order for the second connecting bolt to pass through the outer edge 222, the outer edge 222 is pre-arranged with a through hole, and correspondingly, the groove 211 is correspondingly provided with a threaded hole for the second connecting bolt to be screwed in. After the nozzle 220 is installed, the surface of the outer edge 222 is tightly attached to the bottom surface of the groove 211 to achieve sealing. Preferably, a sealing gasket or other components can be arranged between the outer edge 222 and the groove 211 to improve the sealing.

[0048] It can be understood that the shield 100 is provided with a clamping assembly 300 , and the clamping assembly 300 is located at an end away from the base 210 , and the clamping assembly 300 is used to fix the shield 100 .

[0049] The shield 100 is conveniently fixed to the installation position of the detection head by using the clamping assembly 300. It is understandable that in some embodiments, the clamping assembly 300 includes a pair of clamping plates 310, both of which are connected to the ends of the shield 100, and the two clamping plates 310 are relatively spaced apart, and a third connecting bolt is inserted between the two clamping plates 310, and the third connecting bolt is used to adjust the distance between the two clamping plates 310.

[0050] Generally, the detection head is also fixedly mounted on a column or a rod. Taking a rod as an example, the detection head is set at the end of the rod, and after the shield 100 is sleeved on the outside of the detection head, the two clamping plates 310 can just be on the side of the rod, and by adjusting the third connecting bolt, the two clamping plates 310 are brought close to each other and clamped on the rod, and the third connecting bolt is continuously applied with torque, so that the clamping plates 310 can be stably connected to the rod.

[0051] It can be understood that the two opposite surfaces of the two clamping plates 310 are respectively provided with arc-shaped portions 311 , and the two arc-shaped portions 311 surround a clamping position.

[0052] When the clamping assembly 300 is connected to a rod or a column, the arc portion 311 provided on the clamping plate 310 can increase the contact area between the clamping plate 310 and the rod or the column, which can not only reduce the stress exerted by the rod or the column on the clamping plate 310, but also improve the stability of the clamping of the clamping plate 310.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
